In this paper, we investigate use of stochastic network modeling techniques for analyzing supply chain networks. Supply chains are interconnections of several companies such as suppliers, manufacturers, distributors and retailers with the aim of producing and selling customer desired products. Computing the supply chain lead time, or the order-to-delivery time is an important exercise. In this paper, we present stochastic network models for computing the average lead times of make-to-order supply chains. In particular, we illustrate the use of static probabilistic networks for computing the lead times.

Lesson Title: Stochastic Models for Supply Chain Networks

Introduction:
Supply chain management involves coordinating the movement of goods and services from suppliers to customers. It is a complex process that requires efficient planning, organization, and control of resources. This lesson will introduce you to stochastic models used in analyzing supply chain networks.

Core Value:
The core value of this lesson is to understand the use of stochastic network modeling techniques in analyzing supply chain networks.

Section 1: What is a Supply Chain Network?
A supply chain network is a group of interconnected companies that work together to produce and sell products to customers. These companies include suppliers, manufacturers, distributors, and retailers. The supply chain network is responsible for managing the flow of goods and services from raw materials to the final consumer.

Section 2: Why Use Stochastic Models in Supply Chain Networks?
Stochastic models are useful in supply chain networks because they help to predict the future behavior of the system. They take into account the uncertainties and variabilities that arise in supply chain management, such as fluctuations in demand, lead times, and inventory levels. By using stochastic models, companies can better plan and manage their supply chain networks, reducing costs and improving customer satisfaction.

Section 3: How do Stochastic Models Work in Supply Chain Networks?
Stochastic models use probability theory to represent the uncertainties and variabilities in supply chain networks. They are based on the assumption that future events will follow a random pattern. By analyzing historical data and applying statistical techniques, stochastic models can predict the likelihood of different outcomes.

Example:
Suppose a company wants to calculate the average lead time for its make-to-order supply chain. Using a stochastic model, the company can simulate the supply chain network and estimate the average lead time based on historical data. This information can then be used to optimize the supply chain network and improve customer satisfaction.

Section 4: Conclusion
In conclusion, stochastic models are essential tools in supply chain management. They help companies to plan and manage their supply chain networks more effectively by taking into account the uncertainties and variabilities that arise in the system. By understanding the principles of stochastic modeling, you can apply these techniques to analyze your own supply chain network and improve its performance.

Glossary:
- Stochastic: A term used to describe a process that follows a random pattern.
- Probability Theory: A branch of mathematics that deals with the study of chance and probability.
- Make-to-Order: A production method where products are made only after receiving an order from a customer.

Self-Debate Discussion:
- How can stochastic models be applied to other areas of business, such as product development or marketing?
- What are some limitations of stochastic models in supply chain management?
- How can companies ensure that their supply chain networks are efficient and effective?

Lesson: Understanding Influenza and Its Variants

Introduction:
Influenza, commonly known as the flu, is an infectious respiratory illness caused by the influenza virus. It affects millions of people worldwide each year. In this lesson, we will learn about the different types of influenza, its transmission, and prevention methods.

Section 1: Understanding Influenza

**Topic 1: Types of Influenza**

Influenza comes in two types: seasonal and pandemic. Seasonal influenza occurs annually and affects people during certain times of the year. Pandemic influenza occurs when a new strain of the virus emerges and spreads quickly around the world.

**Topic 2: Transmission of Influenza**

Influenza is primarily spread through respiratory droplets when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people nearby or be inhaled into the lungs. The virus can also be spread by touching surfaces contaminated with the virus and then touching the mouth, nose, or eyes.

**Topic 3: Symptoms of Influenza**

Symptoms of influenza include fever, cough, sore throat, body aches, headache, fatigue, and sometimes vomiting and diarrhea. These symptoms usually appear one to four days after exposure to the virus.

Section 2: Preventing Influenza

**Topic 1: Vaccination**

Vaccination is the most effective way to prevent influenza. The flu vaccine is updated each year to protect against the most common strains of the virus. It is recommended that everyone six months of age and older receive a flu vaccine each year.

**Topic 2: Handwashing**

Handwashing is another effective way to prevent the spread of influenza. Wash your hands frequently with soap and water for at least 20 seconds, especially after being in contact with someone who has the flu or after touching surfaces that may be contaminated with the virus.

**Topic 3: Respiratory Hygiene**

Cover your mouth and nose with a tissue when coughing or sneezing. If you do not have a tissue, use the crook of your elbow. Dispose of used tissues in a lined trash can and wash your hands immediately.

Section 3: Conclusion

In conclusion, understanding influenza and its variants is crucial in preventing its spread. By getting vaccinated, practicing good hand hygiene, and covering our mouths and noses when coughing or sneezing, we can reduce the risk of contracting or spreading the virus. Additionally, staying home when feeling sick and seeking medical attention if necessary can help control the spread of influenza.

Exploring 4,600 Miles of Opportunities

February 29, 2012

Marsha McDaniel is a Commercial Officer in the Mumbai, India office of the Commercial Service.

Led by the Under Secretary of Commerce for International Trade, Francisco Sánchez, the first-ever Ports and Maritime Technology Trade Mission to India introduced twelve U.S. companies to the entire maritime territory of India, spanning from Kolkata in the east, to Chennai in the south, and ending in Ahmedabad and Mumbai in the west.

Under Secretary Sanchez and Commercial Service staff with the Trade Mission delegates

India, with its vast coastline of 4,600 miles, offers abundant opportunities for U.S. ports and maritime technology companies. During their visit the trade mission delegates traveled nearly 2,000 miles within India and they participated in more than 200 customized business meetings.

The participating organizations included two premier U.S. seaports – the Port of Baltimore and the Port of San Diego – as well as ten leading U.S. companies that provide port technologies including dredging, port security, and logistics.

Starting in Kolkata on February 17th seven participating companies visited the eastern region of India to explore commercial opportunities at the Haldia Port. This was the first major U.S. trade mission to visit Kolkata since 2008, and the delegates were warmly received by the local business community and the Commercial Service Kolkata team.

The official trade mission kicked-off in Chennai on Monday February 20, where Under Secretary Sánchez, Commercial Service India’s Minister Counselor Judy Reinke and the Commercial Service Chennai team welcomed the full delegation of twelve companies. Also participating in the mission were representatives from the U.S. Trade and Development Agency and the Overseas Private Investment Corporation.

While in Chennai the Under Secretary and the delegates met with India’s Minister of Shipping, Shri G.K. Vasan, and participated in matchmaking sessions organized by local business chambers.

The Commercial Service Ahmedabad team orchestrated a series of meetings for the delegates with various Gujarati ports while the Under Secretary participated in government meetings with state officials. Under Secretary Sánchez ended his trip to Ahmedabad with a visit to the Pandit Deendayal Petroleum University where he engaged in a lively discussion with nearly 200 students.

Mumbai, the commercial capital of India, was the final stop of the mission. On February 23rd the delegates participated in a busy day of customized business meetings with potential Indian partners. While in Mumbai Under Secretary Sánchez participated in a SelectUSA event with leading Indian IT companies and he later inaugurated the new Commercial Service Trade Center at the U.S. Consulate in Mumbai.

Trade Mission delegates visit Mumbai’s JNTP Port

The mission participants received a special access comprehensive tour of the Jawaharlal Nehru Port Trust (JNTP), thanks to the efforts of the Commercial Service teams in New Delhi and Mumbai. During the tour, delegates had an intimate meeting with the JNTP Port Chairman during which they discussed specific commercial opportunities related to dredging and port security.

The delegates completed the mission feeling optimistic about the commercial opportunities in this sector. The companies realize that doing business in India is a long-term proposition and this will be the first of hopefully many visits to India that the companies will make. The Commercial Service team in India is standing by to assist U.S. firms create lasting partnerships that will help bring American port and maritime technology solutions to India.

This mission was the first of several infrastructure-related events that will take place in India this year. The U.S. Secretary of Commerce, John Bryson, will lead an infrastructure trade mission to New Delhi, Jaipur, and Mumbai during March 25-30.

I think that it’s a great idea to expand the options of commerce with India and as mentioned above by Sara I would consider including more ports to increase commerce exchange between these two nations via sea sources.

Activin receptor-like kinase 7 mediates high glucose-induced H9c2 cardiomyoblast apoptosis through activation of Smad2/3.
Cardiomyocyte apoptosis is an important pathological change of diabetic cardiomyopathy. How the elevated glucose levels cause cell apoptosis remains unknown. The aim of our study was to investigate whether activin receptor-like kinase 7 (ALK7)-Smad2/3 signaling pathway plays an important role in high glucose-induced cardiomyocyte apoptosis. H9c2 cardiomyoblasts and neonatal rat cardiomyocytes were treated with 33mmol/l glucose. The expression of ALK7, Smad2 and Smad3 were inhibited by small interfering RNA respectively. The level of ALK7, total Smad2/3, phosphorylated Smad2/3, B-cell lymphoma-2 (Bcl-2) and cleaved Caspase3 were evaluated using western blot. The apoptosis rate was detected by flow cytometer. High glucose treatment caused the apoptosis of H9c2 cardiomyocyte and the inhibition of Smad2 or Smad3 attenuated this apoptosis. ALK7 existed in both H9c2 cardiomyoblasts and neonatal rat cardiomyocytes and high ambient glucose upregulated its expression. The increased expression level of cleaved Caspase3 and apoptosis rate and decreased expression of Bcl-2 were reversed after ALK7 was inhibited. The expression of phosphorylated Smad2/3 also decreased after the knockdown of ALK7. Our findings suggest that ALK7 mediates high ambient glucose-induced H9c2 cardiomyoblasts apoptosis through the activation of Smad2/3.

Lesson Title: Understanding Diabetic Cardiomyopathy: The Role of ALK7-Smad2/3 Signaling Pathway in High Glucose-Induced Cardiomyocyte Apoptosis

Introduction:
Cardiomyopathy is a disease that affects the heart muscle, leading to its weakening and dysfunction. Diabetic cardiomyopathy is a type of cardiomyopathy that occurs in individuals with diabetes. It is characterized by the presence of structural and functional abnormalities in the heart, such as left ventricular hypertrophy, diastolic dysfunction, and heart failure. One of the key mechanisms underlying diabetic cardiomyopathy is the induction of cardiomyocyte apoptosis, or programmed cell death. In this lesson, we will explore the role of the ALK7-Smad2/3 signaling pathway in high glucose-induced cardiomyocyte apoptosis and its implications for diabetic cardiomyopathy.

Section 1: Understanding Cardiomyocyte Apoptosis

Cardiomyocyte apoptosis is a process of programmed cell death that occurs in the heart muscle. It is a complex process involving several steps, including initiation, execution, and clearance. Initiation involves the activation of pro-apoptotic proteins, such as Bax and Bak, which trigger the release of cytochrome c from the mitochondria. This leads to the activation of caspases, a family of proteases that play a crucial role in the execution of apoptosis. Finally, clearance involves the removal of apoptotic cells by phagocytosis.

Section 2: The ALK7-Smad2/3 Signaling Pathway and Cardiomyocyte Apoptosis

The ALK7-Smad2/3 signaling pathway is a key mediator of TGF-β family members, which are involved in various cellular processes, including cell growth, differentiation, and apoptosis. In the context of cardiomyocyte apoptosis, the ALK7-Smad2/3 pathway has been shown to play a critical role in the regulation of cell survival and death. When exposed to high glucose levels, cardiomyocytes undergo a series of changes that lead to the activation of the ALK7-Smad2/3 pathway, ultimately resulting in the induction of apoptosis.

Section 3: Experimental Evidence for the Role of ALK7-Smad2/3 Signaling Pathway in High Glucose-Induced Cardiomyocyte Apoptosis

To investigate the role of the ALK7-Smad2/3 signaling pathway in high glucose-induced cardiomyocyte apoptosis, researchers used H9c2 cardiomyoblasts and neonatal rat cardiomyocytes. These cells were treated with 33mmol/l glucose, a concentration that is known to induce apoptosis in cardiomyocytes. The expression of ALK7, Smad2, and Smad3 was inhibited using small interfering RNA (siRNA), which allowed researchers to evaluate the effect of this pathway on apoptosis.

Results showed that high glucose treatment caused the apoptosis of H9c2 cardiomyocytes and the inhibition of Smad2 or Smad3 attenuated this apoptosis. ALK7 existed in both H9c2 cardiomyoblasts and neonatal rat cardiomyocytes and high ambient glucose upregulated its expression. The increased expression level of cleaved Caspase3 and apoptosis rate and decreased expression of Bcl-2 suggested that the ALK7-Smad2/3 signaling pathway played a crucial role in high glucose-induced cardiomyocyte apoptosis.

Section 4: Conclusion

In conclusion, the ALK7-Smad2/3 signaling pathway is a critical mediator of high glucose-induced cardiomyocyte apoptosis. Targeting this pathway may provide a novel therapeutic strategy for the prevention and treatment of diabetic cardiomyopathy. As diabetic cardiomyopathy is a major complication of diabetes and a leading cause of heart failure, understanding the molecular mechanisms underlying this condition is essential for the development of effective treatments.

Glossary:
- ALK7: Activin receptor-like kinase 7
- Smad2/3: Signal transducers and activators of transcription 2 and 3
- Bcl-2: B-cell lymphoma-2
- Caspase3: Cysteine aspartate-specific protease 3

Self-Debate Discussion:

Is there evidence to support the claim that the ALK7-Smad2/3 signaling pathway plays a critical role in high glucose-induced cardiomyocyte apoptosis?

Yes, there is experimental evidence from in vitro studies using H9c2 cardiomyoblasts and neonatal rat cardiomyocytes that show that high glucose treatment causes the apoptosis of these cells and that inhibiting the expression of ALK7, Smad2, or Smad3 attenuates this apoptosis. Additionally, the expression of cleaved Caspase3 and apoptosis rate is increased, while the expression of Bcl-2 is decreased, suggesting that the ALK7-Smad2/3 signaling pathway plays a critical role in high glucose-induced cardiomyocyte apoptosis.

The present invention relates to refrigeration, and to separation, and more particularly to separating fluid mixtures into dilute components and concentrated components by freezing and then melting the frozen fluid. Fluid mixtures include suspensions, solutions, emulsions and the like.
Freeze-melt techniques in the present field of art may be exemplified by several prior art applications of these techniques. For instance, Hadzeriga, in U.S. Pat. No. 3,681,931, describes the treatment of phosphate rock slimes by freezing. Upon melting, the mixture separates into a top layer of clear liquid substantially free of suspended matter and a bottom layer of concentrated suspension.
Phosphate slime is a colloidal, aqueous suspension which is normally difficult to separate and is left in large settling ponds appurtenant to the mining operation which produced it. In the freeze-melt process, the slime is "statically frozen" by freezing a substantial portion of the liquid in a quiescent, non-agitated state to temperatures preferably between -20.degree. C. and -80.degree. C. Slow freezing produces better separation by producing larger ice crystals to compact suspended solids. After freezing, static thawing is carried out at ambient temperature.
Prior art processes and equipment for the treatment of phosphate slimes have, insofar as is known, heretofore been of the "bulk freezing" type wherein a container of slime is filled, frozen, melted and decanted. After the separated components have been removed, the container is refilled, and the cycle is begun again.
Freeze-melt techniques have also been applied to treatment of sewage sludge. Sewage sludge is an aqueous organic colloidal suspension which is difficult to separate by filtration or settling. Sludge which has been frozen and melted can be filtered quite easily, however. Sludge freezing process efficiency has been found to be independent of freezing temperature, length of time the sludge was kept frozen, and the thickness of the sludge. Process efficiency does, however, depend on the slow and full freezing of the sludge.
A sludge freezing plant typically employs a vapor compression refrigeration type system. Ammonia may be used as the refrigerant. The sludge is contained in a first large tank and cold, vaporizing ammonia is passed through an evaporator comprising vertical pipes passing through the tank. The hot, vaporized ammonia is then passed through pipes in a second tank which holds previously frozen sludge which is to be melted by the warm vapor. When a tank is fully frozen, the flow of ammonia is reversed, and melting begins in the first tank, and freezing begins in the second. After a "batch" has been melted, the tank contents are emptied through the bottom of the tank and passed to a filter for separation.
Freeze-melt techniques have also been applied to the desalinization of sea water. Separation is based on the fact that when salt water is partially frozen, the ice crystals that form are free of salt. In a desalinization plant described by G. Karnofsky in Chemical Engineering Progress, Volume 57, No. 1, January 1961, p. 42, butane is used as the refrigerant in a vapor compression refrigeration system. The seawater is frozen by a direct contact with boiling butane at slightly less than 1 atm. pressure. The butane vapor from the freezer is then compressed and condensed by cold from previously formed ice. The vapor in turn warms and melts the ice. Melted water is passed out through a heat exchanger against entering seawater. The condenser and heat exchanger arrangement is designed to improve the thermal efficiency of the system.
Briefly, in a vapor compression system, the refrigerant in a vapor phase is first compressed by a compressor, then cooled in a condenser to liquid form. This is the high pressure side of the system. The liquid refrigerant then passes through an expansion valve, which maintains pressure on the high side, to the low pressure side of the system. There, the refrigerant passes through an evaporator, where it is vaporized and expands, thus absorbing heat and causing refrigeration of the material surrounding the evaporator. The vaporized refrigerant is passed to the compressor to complete the cycle. Just as heat is absorbed by the refrigerant due to vaporization in the evaporator, heat is liberated in the condenser due to the condensation there.
A principal problem to be overcome in a freeze-melt process is thermal efficiency. The thermal efficiency of a vapor compression refrigeration system is related to the condenser and evaporator temperatures. The thermal efficiency of a refrigeration system may be expressed as: ##EQU1## where: T.sub.1 =evaporator temperature, absolute;
T.sub.2 =condensing temperature, absolute; and PA1 C.O.P.=the coefficient of performance of the refrigeration cycle. PA1 h.sub.d =enthalpy of vapor leaving the compressor, B.t.u./lb; and PA1 hg=enthalpy of vapor entering the compressor, B.t.u./lb.
The heat of compression is expressed as: EQU Heat of compression=h.sub.d -h.sub.g ( 2)
where:
Enthalpy refers to the heat content of the refrigerant. The net refrigeration effect refers to enthalpy lost in the evaporator. It can be seen from equation (1) above that the smaller the difference between the evaporator temperature and the condensing temperature, the more efficient the process will be. Since enthalpy of the vapor is related to temperature, equation (2) demonstrates that lowering the necessary compressor temperature and pressure differences will also increase refrigeration efficiency.

These methods can be used to separate mixtures based on their properties, such as solubility, boiling point, or particle size.

**Section 2: Examples of Separation Techniques**

Filtration is commonly used to separate solid particles from a liquid. For example, coffee filters are used to separate coffee grounds from coffee. Evaporation can be used to separate a solvent from a solution. For instance, salt can be separated from water by evaporating the water and leaving the salt behind. Distillation is used to separate components of a mixture based on their boiling points. For example, alcohol can be separated from water by distilling them at different temperatures. Crystallization is used to separate solids from a solution. For example, sugar can be separated from a sugar solution by crystallizing it. Freeze-melt techniques can be used to separate components of a mixture based on their solubility. For example, phosphate slime can be separated into a clear liquid and a concentrated suspension by freezing and melting the mixture.

**Section 3: Applications of Separation Techniques**

Separation techniques are used in various fields, including pharmaceuticals, food processing, and environmental science. In pharmaceuticals, separation techniques are used to isolate and purify active ingredients from medicinal plants. In food processing, separation techniques are used to separate different components of food products, such as fats, proteins, and carbohydrates. In environmental science, separation techniques are used to remove pollutants from air, water, and soil.

**Conclusion:**

In this lesson, we introduced the concept of separation techniques in chemistry and their applications in various fields. We discussed the different methods of separation and provided examples of each technique. We also explored the applications of separation techniques in different fields. By understanding the principles of separation techniques, students can apply these techniques to new problems and develop innovative solutions.


text: In order to evaluate the risk in SV systems one should take into account the possible perpetrator who knows whom he/she is attacking. This paper thus evaluated if a large speech corpus can be used for selecting impostors to use against a speaker verification (SV) system. We tested the possibility by selecting the most similar speakers from a large corpus and then using the recordings in this corpus for impostor attempts against clients in an SV system. Speech samples of the clients uttering words not used in the SV service was used in order to search the large corpus for similar speakers. Recordings of utterances used in the SV service was then collected from these similar speakers and used for impostor attempts. Our conclusion is that this scenario is a threat that needs to be considered by providers of SV systems.

Researchers in Western Australia have discovered that 1080 baits laid for wild dogs are being eaten mostly by goannas that are resistant to the poison.

Preliminary results from Murdoch University and the Department of Agriculture and Food reveal that dogs rarely eat the 1080-injected dried meat baits, but non-target species do.

The research was carried out in the Meekatharra area of mid-west WA, where motion sensor cameras were set up in front of baits.

Murdoch University postdoctoral research fellow Tracey Kreplins said she and her colleagues had watched footage from about 200 sites, and would be doing another 100 in coming weeks.

"There's a lot of interference from non-targets taking baits, things like varanids [goannas], ravens, kangaroos, ants, and feral cats," Dr Kreplins said.

"There's a big seasonal effect. In summer the varanids are out and are very busy.

"Varanids can take quite a lot of the baits within 48 hours of them being placed, so the dogs aren't even getting a look-in."

Wild dogs look at baits then leave them

Dr Kreplins said when the varanids disappeared in winter, baits sat untouched for up to two months.

"No one's taking them. They're just sitting there, but still we haven't had many wild dogs at all take the baits," she said.

Dr Kreplins said researchers did not know why the dogs were not eating the baits.

"There's a lot of evidence that wild dogs are coming up to the baits and having a look, even rolling in the baits, but they're not taking them," she said.

"There's a few taking them — mostly younger dogs, not so much the older dogs — but I can't answer that yet."

Science backs up anecdotal evidence

Dr Kreplins said the findings backed up views held widely in the pastoral community that dogs did not take baits.

"We keep proving them right. We keep proving that the people on the land know what they're talking about," she said.

"I'm surprised at how quickly the baits go. Sometimes we were laying baits and you'd turn around and there was a varanid following you down the track, eating the baits as you were putting them out."

Dr Kreplins said the next step would be to trial the efficacy of canid pest ejectors (CPE).

"Only foxes and wild dogs have the power to pull off the bait head and eject the 1080 into their mouth," she said.

"If baits are disappearing to everything else but a wild dog, hopefully CPEs stop all that non-target interference and just target wild dogs."

text: Hi, I am new to this forum. I have an American Jazz Bass, from the 80's. I bought it couple of months ago, from a friend. I found the action cool when I bought it, but not any more (this bass was DEFRETTED). I measured everything to discribe what is the bass like at the moment, and I am wondering, if you have any tips to lower the action. NUMBERS: Holding the first and the last fret, (string 4)I checked the gap on the 8th fret, and it's around 0.011". Holding the third fret, string 4, the gap between the first fret and the string is .015. With a ruller, the gap fretboard to string 4 on the 17 fret 6/64. The neck is flat, as much as I could. The saddles, are pretty low (I am wondering, does fretless has different saddlers, so it can go more down?). Any tips, on reducing buzz while lowering the action? Thanks for looking,

textbook:
Lesson: How to Lower the Action on Your Guitar
Introduction:
Lowering the action on your guitar is essential if you want to play it smoothly without any buzzing or fret noise. In this lesson, we will learn how to measure the action, identify the problem areas, and adjust the bridge and truss rod to lower the action.
Section 1: Understanding the Basics
- Action refers to the distance between the strings and the fretboard when a note is played.
- A lower action means that the strings are closer to the fretboard, making it easier to play chords and melodies.
- However, a very low action can cause buzzing and fret noise.
Section 2: Measuring the Action
- To measure the action, hold the first and last frets on the fourth string.
- Measure the gap between the first fret and the string.
- If the gap is too high, it means that the action is too high.
- You can also use a ruler to measure the gap between the fretboard and the string on the 12th fret.
Section 3: Identifying the Problem Areas
- If the action is too high, it could be caused by a high bridge or a straight neck.
- A high bridge can be adjusted by shimming it with a piece of paper or cardboard.
- A straight neck can be fixed by adjusting the truss rod.
Section 4: Adjusting the Bridge and Truss Rod
- To adjust the bridge, loosen the screws and shim the bridge with a piece of paper or cardboard.
- Adjust the saddle height so that the strings are close to the fretboard.
- Tighten the screws and check the action.
- To adjust the truss rod, loosen the nut and turn the rod clockwise or counterclockwise until the neck is straight.
- Tighten the nut and check the action.
Section 5: Reducing Buzz While Lowering the Action
- If you hear buzzing while playing, it could be caused by the strings vibrating against the frets.
- To reduce buzzing, use a cleaner such as lemon oil to clean the frets.
- You can also polish the frets with a fine-grit sandpaper.
Conclusion:
Lowering the action on your guitar is essential for playing it smoothly and without any buzzing or fret noise. By following the steps outlined in this lesson, you can adjust the bridge and truss rod to lower the action and reduce buzzing. Remember to measure the action, identify the problem areas, and adjust the bridge and truss rod accordingly.

Brian Boru is celebrated as a patron of the arts and is often thought to have played the harp. Given his prominence as a figure in medieval Ireland, it is hardly surprising that one of the three harps surviving from medieval Ireland became associated with him.

© Trinity College, University of Dublin

Although the the so-called 'Brian Boru harp', now kept in Trinity College Dublin (hence its other name, 'the Trinity harp'), has long been claimed to be the harp of Brian Boru, the harp actually dates from the fourteenth or fifteenth century.

Roman Holiday

According to one legend, Brian Boru’s son Donogh/Donnchad is said to have presented the Pope with his father’s harp and crown on a visit to Rome in 1064.

The story goes that it resided in the papal collection until 1521 when Pope Leo sent it to King Henry VIII of England to celebrate his new title as ‘Defender of the Faith’. Although Henry's relations with the pope went rapidly downhill after his split from Rome, he must have hung onto the harp, because he apparently gave it to the first Earl of Clanricarde. The harp is then said to have had a number of owners until, eventually, it was presented to Trinity College Dublin by William Conyngham in 1782 where it can now be viewed in the Long Room Library.

Did you know? The Brian Boru harp was stolen for a short period in 1969.

A Symbol of Ireland

In the mid 1700s the blind Tyrone harper Arthur O’Neill was invited to restring the Brian Boru Harp and play it in a parade through Limerick.

He describes the event in his memoirs:

I played several tunes … and I was followed by a procession of upwards of five hundred people, both gentle and simple, as they seemed to be every one imbibed with a national spirit when they heard it was the instrument that our celebrated Irish monarch played upon before he leathered the Danes at Clontarf out of poor Erin. The Lord be merciful to you, Brian Boru! I hope in God I will tune your harp again in your presence in heaven! And if it should be the case, upon my honour and conscience I will not play the tunes of July the First nor The Protestant Boys; but I would willingly play God Save the King, and that would be for yourself, Brian! " Arthur O'Neill, ‘Memoirs’ in Donal O'Sullivan, Carolan, the Life, Times and Music of an Irish Harper, (London, 1958).

Whatever its history, the Irish harp remains central to the depiction of Irishness. A harp has appeared on Irish coins since King Henry VIII’s time, and the Brian Boru harp is now the national symbol of Ireland.

© Caoimhe Ní Faoláin 2014

As the official emblem of Ireland it also appears on the Presidential seal, every Irish passport, and is used in the coat-of-arms of the National University of Ireland as well as being recognised (backwards) around the world as the symbol of the black stuff: Guinness, the quintessensial drink of the Irish.

Music in Medieval Ireland

Giraldus Cambrensis (Gerald of Wales), the twelfth-century Anglo-Norman chronicler is not known for his praise of the Irish but he has some positive things to say about their music (so it must have been pretty impressive). Giraldus explains that:

The only thing to which I find that this people apply a commendable industry is playing upon musical instruments, in which they are incomparably more skilful than any other nation I have ever seen. For their modulation on these instruments, unlike that of the Britons to which I am accustomed, is not slow and harsh, but lively and rapid, while the harmony is both sweet and gay. It is astonishing that in so complex and rapid a movement of the fingers, the musical proportions can be preserved, and that throughout the difficult modulations on their various instruments, the harmony is completed with such a sweet velocity, so unequal an equality, so discordant a concord, as if the chords sounded together fourths or fifths. … It must be remarked, however, that both Scotland and Wales strive to rival Ireland in the art of music ..." Giraldus Cambrensis (Gerald of Wales), The History and Topography of Ireland, trans. Thomas Forester (Cambridge, Ontario, 2000), p. 71.

We will examine the history of the instrument, its association with Brian Boru, and its enduring legacy in Irish culture.

Section 1: The History of the Harp

The harp is one of the oldest stringed instruments in the world, with its origins dating back to ancient Egypt. It was introduced to Ireland by the Celts around 700 AD and quickly became an important part of Irish culture. By the Middle Ages, the harp had become the national instrument of Ireland, and it was often used to accompany poetry and storytelling.

Section 2: Brian Boru and the Harp

Brian Boru was a legendary Irish king who ruled from 1002 to 1014. He is celebrated as a patron of the arts and is often thought to have played the harp. One of the three surviving medieval Irish harps is believed to have been associated with Brian Boru. This harp, now known as the "Trinity Harp," dates from the fourteenth or fifteenth century, but it has long been claimed to be the harp of Brian Boru.

Section 3: The Legacy of the Harp in Medieval Ireland

Despite the fact that the "Trinity Harp" dates from several centuries after Brian Boru's time, it remains an important symbol of Irish culture and heritage. Today, the harp continues to be a prominent symbol of Ireland, appearing on the country's coat of arms and currency.

Conclusion:

In conclusion, the harp played a significant role in medieval Ireland, particularly in the life of Brian Boru. While the "Trinity Harp" may not have belonged to him, it serves as a reminder of the importance of the harp in Irish culture and history. By exploring the history and significance of the harp in medieval Ireland, we can gain a deeper appreciation for the rich cultural heritage of our country.

Lesson: Introduction to Traditional Japanese Craftsmanship

## Section 1: Introduction
In this lesson, we will learn about traditional Japanese craftsmanship and how it is applied to create beautiful and functional items like the Sakura Tea Tin Canister. We will explore the history and techniques behind this craft, as well as the materials used and the impact on the environment. By the end of this lesson, you will have a better understanding of the importance of traditional craftsmanship and how it can be applied to modern-day products.

## Section 2: History and Techniques
Traditional Japanese craftsmanship has been practiced for centuries and is deeply rooted in Japanese culture. It involves the use of natural materials and techniques passed down from generation to generation. The Sakura Tea Tin Canister is an example of this craftsmanship, as it is made using cherry bark, a material that is native to Japan.

The production process of the Sakura Tea Tin Canister is complex and requires skill and patience. First, the cherry bark is harvested from the tree and then sun-dried for several weeks. After that, it is soaked in water for a few days to soften it before being wrapped around the canister. This process is repeated several times until the desired thickness is achieved. Finally, the canister is sealed with a layer of tin to prevent it from expanding and contracting due to changes in temperature and humidity.

The techniques used in traditional Japanese craftsmanship are meticulous and require great attention to detail. For example, the art of origami (paper folding) and kirie (cutting paper) are two such techniques that involve precision and patience. These techniques have been used for centuries to create intricate and beautiful pieces of art, such as the famous Japanese paper cranes.

## Section 3: Materials and Environmental Impact
The materials used in traditional Japanese craftsmanship are often natural and renewable, such as wood, paper, and clay. These materials are chosen for their beauty, durability, and sustainability. In the case of the Sakura Tea Tin Canister, the cherry bark is a renewable resource that is harvested responsibly, ensuring that the tree is not damaged in the process.

However, the production process of traditional Japanese craftsmanship can have an impact on the environment. For example, the use of natural dyes in textiles can result in water pollution if not done responsibly. Therefore, it is essential to consider the environmental impact of traditional craftsmanship and find ways to minimize it while still maintaining the quality and beauty of the final product.

## Section 4: Critical Thinking
As we learn about traditional Japanese craftsmanship, it is essential to think critically about the impact of this craft on the environment and society. For example, we can consider the following questions:

- How can the production process of the Sakura Tea Tin Canister be made more sustainable?
- What other traditional Japanese crafts can be adapted to modern-day products?
- How can we ensure that traditional craftsmanship remains relevant and valuable in today's world?

## Glossary
- Traditional Japanese craftsmanship: A set of techniques and practices used to create beautiful and functional items, often using natural materials.
- Sakura Tea Tin Canister: A tea canister made entirely of cherry bark, lined with tin, and crafted using traditional Japanese techniques.
- Harvest: To cut or gather a crop or natural resource.
- Sun-dried: To dry something in the sunlight.
- Soak: To immerse something in a liquid for a period of time.
- Thickness: The degree of something's thickness or thinness.
- Sustainability: The ability to maintain or preserve something over time.

## Conclusion
In this lesson, we have learned about traditional Japanese craftsmanship and its application in creating the Sakura Tea Tin Canister. We explored the history and techniques behind this craft, as well as the materials used and the impact on the environment. By understanding the importance of traditional craftsmanship and its potential for modern-day products, we can appreciate the beauty and functionality of items created using this technique.

The fear of seeming racist is racist and preventing integration

On Wednesday 27th August, it was reported that 1,400 girls were victims of abuse. Authorities had known for 16 years but did nothing because they feared that speaking out against the perpetrators who were of Pakistani origin would seem racist.

Imagine going to a country where nobody knows who you are, what you do, where you come from, and your religious and cultural beliefs. Now imagine living like that for years and decades. It may not have been too hard to imagine for some, because the idea of ‘love thy neighbour’ no longer exists.

Instead, in this crowded country we are all living worlds apart. Societies and communities are more disjointed than ever and we are all to blame because of the fear of difference.

The report outlined that girls, some as young as 12, were sexually abused, gang raped, beaten and some were impregnated and petrol thrown over them, but South Yorkshire police and Rotherham council ignored the abuse. This was an injustice not only to the victims but also minority communities.

Violence against women can never be justified and neither can the claim that the representatives and upholders of the law were fearful of seeming racist if they reported the abusers.

In fact, it is racist to not have reported them. Distinguishing the perpetrators as Asian men rather than men committing an offence is racist. Exempting Asian men from the law that all British citizens are equal under is racist.

I do not want to dismiss how this case shows that Asian men are being singled out under the law which poses a threat to other girls who may face a similar situation. And I do not want to pass on the fact that the girls were treated horrifically and unequally under the law where their voices went unheard.

But I feel that this entire case shows why there is a problem with integration in society and why multiculturalism is not working. The fear of seeming racist or coming across as racist is leading to segregation because people are too afraid to speak out when they see any wrong-doing by people not of their culture, colour or religion.

I was shocked when I watched the news and saw an interview with a local woman in Rotherham claiming it seemed unusual that girls were always near cars full of Asian men and there seemed to be something suspicion happening – but she had done nothing about it.

The Rotherham child abuse scandal was a narrative about the East and West divide when it should have been a case about crime, law and order.

We have lost the sense of community, society, and even plain humanity because of the fear of difference, religion, culture and terms such as ‘racism’ and ‘islamaphobia’.

Protest in Bristol

In Bristol on Saturday 29th August, 60 people including mothers, fathers and children, protested against institutional racism. One woman wearing a head scarf was seen holding a banner saying ‘we’re yearning for integration’. This highlights the problem minority communities are facing, how the fear of seeming racist is causing segregation, but also that minority communities want to be part of the majority.

We need to start accepting one another as British citizens. We need to open up to differences in cultures and then stand up to any wrong-doing. This has worked in the past when Female Genital Mutilation was being practised in communities in the UK as part of a certain culture but was then illegalised because it was deemed immoral and unethical.

If we are really a multicultural society, we should view each and every individual in this country as an equal, a peer, a British citizen. And we will do everything to prevent any injustices regardless of fearing another’s difference.

Lesson: The Importance of Integration

Introduction:
Integration refers to the process of bringing different groups of people together to form a unified whole. In today's society, integration is more important than ever, as people from different backgrounds come into contact with each other on a daily basis. This lesson will explore the importance of integration and how it can benefit individuals and communities.

Section 1: Why is Integration Important?
Integration is important for several reasons. Firstly, it allows people to learn about different cultures and ways of life, which can lead to greater understanding and respect for others. Secondly, integration can help to break down barriers between groups and promote social cohesion. Finally, integration can provide opportunities for individuals to learn new skills and knowledge, which can benefit both themselves and their community.

Section 2: Examples of Integration
Integration can take many forms, from simple acts of kindness to more formal programs and initiatives. For example, a person may invite their neighbor of a different race or religion over for dinner to learn more about their culture. Alternatively, a community may organize a multicultural event to celebrate the diverse backgrounds of its residents.

Section 3: Challenges to Integration
Despite the benefits of integration, there are also challenges that must be overcome. One common challenge is prejudice and discrimination, which can prevent people from different groups from forming meaningful relationships. Additionally, language barriers and cultural differences can make it difficult for people to communicate and understand each other.

Section 4: Critical Thinking Questions
1. How can individuals contribute to integration in their own communities?
2. What are some examples of successful integration initiatives?
3. What are some potential challenges to integration, and how can they be addressed?

Conclusion:
Integration is an important process that allows individuals and communities to grow and thrive. By learning about and appreciating the differences between us, we can create a more harmonious and understanding world. Through intentional acts of kindness and engagement, we can work towards a more integrated society.

Glossary:
- Integration: The process of bringing different groups of people together to form a unified whole.
- Social cohesion: The degree of social harmony and unity within a society.
- Prejudice: A negative opinion or feeling formed beforehand or without proper evidence.

Self-Debating Discussion:
Is integration always easy? Why or why not? Use evidence from the text to support your answer.

Lesson: Introduction to Computer Hardware

**Section 1: Introduction to Computer Hardware**

Computer hardware refers to the physical components that make up a computer system. These components work together to perform tasks and store data. In this lesson, we will explore the different types of computer hardware and their functions.

**Section 2: Types of Computer Hardware**

There are several types of computer hardware, including input devices, output devices, and internal components.

- **Input Devices:** These are used to enter data into the computer system. Examples include keyboards, mice, and microphones.
- **Output Devices:** These display or output information to the user. Examples include monitors, speakers, and printers.
- **Internal Components:** These are the parts that make up the computer's central processing unit (CPU). Examples include the motherboard, CPU, memory (RAM), storage devices (hard drives or SSDs), and graphics cards.

**Section 3: Functions of Computer Hardware**

Each type of computer hardware serves a specific function in the overall operation of the computer system.

- **Input Devices:** Allow users to enter data into the computer system. For example, a keyboard allows users to type words and numbers into the computer, while a mouse allows users to navigate and interact with on-screen elements.
- **Output Devices:** Display or output information to the user. For example, a monitor displays visual information, while a speaker outputs audio information.
- **Internal Components:** Work together to process data and perform tasks. The CPU is responsible for executing instructions and performing calculations, while the RAM temporarily stores data that the CPU is currently working on. The storage device provides long-term storage for data and programs. The graphics card is responsible for rendering images and displaying them on the monitor.

**Section 4: Practical Examples**

Let's consider a scenario where someone wants to create a document using a computer. They would use an input device like a keyboard to type the text and any other content into the document. The CPU and RAM would process the input and store any necessary data. An output device like a monitor would display the document, allowing the user to read and edit it. Finally, a storage device like a hard drive or SSD would store the completed document for future access.

**Section 5: Self-Debating Discussion**

Why are input devices like keyboards and mice still relevant in today's world of touchscreens and voice recognition?

- Some people prefer using physical keyboards and mice for tasks that require precision or speed, such as gaming or coding.
- Keyboards and mice can be more efficient for entering large amounts of text or navigating complex interfaces.
- Touchscreens and voice recognition technologies are not always accurate or reliable, especially in noisy environments or when dealing with complex commands.

**Glossary**

- CPU: Central Processing Unit - the "brain" of the computer that performs calculations and executes instructions.
- RAM: Random Access Memory - temporary storage that the CPU uses to store data it is currently working on.
- Storage Device: A component that provides long-term storage for data and programs.
- Graphics Card: A component responsible for rendering images and displaying them on the monitor.

**Conclusion**

Understanding the different types of computer hardware and their functions is essential for anyone interested in computers or technology. By mastering these concepts, you can apply your knowledge to troubleshoot problems, build your own computer, or simply become a more informed user.


text: This is a work in progress at the moment with photos posted here to get some feedback from gamers before we move into production.. The idea is to use standard Terra-Blocks and the supply floors / roofs which use the same concept as our Warchest Lids, i.e. a lip top and bottom to hold firmly in place.. We would make these available in a wide number of sizes from 150mm x 150mm upwards in 50mm increments in various shapes (square / rectangular, L, T, H).. Multi-story buildings with detailed, but more importantly changeable interiors could then be constructed that can be lifted apart without risk of slippage during play.. This would be too expensive to do for every building on your table, and unnecessary to, but for the key objective buildings that you are going to be fighting through, it opens up a lot of possibilities.

Lesson Title: Introduction to Intensive Care Medicine for Children

Overview:
Intensive care medicine (ICM) is a specialized field of medicine that deals with the care of critically ill patients. While most ICM units focus on adult patients, there is a growing need for pediatric intensive care services. This lesson provides an introduction to intensive care medicine for children, covering the basics of pediatric ICM, including the pathophysiology of childhood diseases, diagnostic approaches, and treatment recommendations.

Section 1: Basics of Pediatric Intensive Care Medicine

Topic 1: Pathophysiology of Childhood Diseases
- Children are not just small adults, and their physiology is different from that of adults.
- Understanding the differences in physiology is crucial for providing appropriate care to critically ill children.
- Some common differences in childhood diseases include:
    - Respiratory issues: Children have smaller airways and may develop respiratory distress more easily than adults.
    - Cardiovascular issues: Children's circulatory systems are immature, making them more susceptible to shock and other cardiovascular problems.
    - Neurological issues: Children's brains are still developing, making them more vulnerable to neurological damage from illness or injury.

Topic 2: Diagnostic Approaches
- Diagnosing a child's illness requires a thorough understanding of their medical history, physical examination, and any previous test results.
- Common diagnostic tools used in pediatric ICM include:
    - Blood tests: To check for infections, electrolyte imbalances, and other conditions.
    - Imaging studies: Such as X-rays, CT scans, and MRIs, to visualize internal organs and detect abnormalities.
    - Monitoring devices: Including pulse oximetry, EKG, and echocardiography, to measure vital signs and assess organ function.

Topic 3: Treatment Recommendations
- Treatment for critically ill children depends on the underlying cause of their illness and their individual needs.
- Common treatments used in pediatric ICM include:
    - Medications: To manage pain, reduce inflammation, and treat infections.
    - Mechanical ventilation: To support breathing in children with respiratory distress.
    - Fluid therapy: To maintain hydration and blood pressure in critically ill children.
    - Nutritional support: To ensure proper growth and development while in the ICU.

Section 2: Practical Examples Using Mathematical Abstractions and Real-World Scenarios

Topic 1: Calculating Doses of Medications
- Dosing medications for children requires knowledge of their age, weight, and medical condition.
- Common dosing formulas used in pediatric ICM include:
    - Body surface area: To calculate the correct dose of medication based on a child's body size.
    - Age and weight-based dosing: To adjust the dose of medication based on a child's age and weight.
- Example: A 6-month-old baby weighing 10 kg with respiratory distress requires 0.5 mg/kg of albuterol every 4 hours.

Topic 2: Interpreting Arterial Blood Gas Results
- Arterial blood gas (ABG) tests measure the levels of oxygen and carbon dioxide in a patient's blood.
- Understanding ABG results is essential for managing critically ill children with respiratory issues.
- Example: An ABG result shows a pH of 7.2, PCO2 of 45 mmHg, and PO2 of 80 mmHg. This indicates respiratory acidosis and hypoxia, requiring immediate intervention.

Section 3: Self-Debating Discussions

Topic 1: Weighing the Risks and Benefits of Mechanical Ventilation
- Mechanical ventilation can be lifesaving for critically ill children with respiratory distress.
- However, it also carries risks, such as lung injury and infection.
- Debate: Should mechanical ventilation be used in a 2-year-old child with severe respiratory syncytial virus (RSV) infection?
- Pros: Mechanical ventilation can support breathing and prevent further lung damage.
- Cons: The risk of lung injury and infection may outweigh the benefits, especially in a young child.

Topic 2: Managing Pain in Critically Ill Children
- Pain management is an essential part of pediatric ICM.
- However, critically ill children may be unable to communicate their pain, making it difficult to assess their level of comfort.
- Debate: Should pain medications be administered to a comatose child with a high likelihood of brain injury?
- Pros: Pain management can improve the child's comfort and quality of life.
- Cons: The risk of sedation and respiratory depression may outweigh the benefits.

Conclusion:
Intensive care medicine for children is a complex and specialized field that requires a deep understanding of pediatric physiology, diagnostic approaches, and treatment recommendations. By mastering the basics of pediatric ICM, health-care providers can provide the best possible care for critically ill children and help them recover from their illnesses.
