Q:

Select case mess in JFreeChart

I have a Column(cliente_x_hora, a numeric field) i put in a interval and count the number in each interval.I have 3 textfields(number of intervals,value between intervals and initial value). When I select the two first(with 5 intervals and 1000 value), the query run flawless and generate the expect barchart.
Query(with two select textfields):
SELECT INTERVAL, COUNT(*) TOTAL FROM (
SELECT CASE WHEN CLIENTE_X_HORA>0 AND CLIENTE_X_HORA<=1000.00 THEN '0<CLIENTE_X_HORA>  <=1000.00'
WHEN CLIENTE_X_HORA>1000.00 AND CLIENTE_X_HORA<=2000.00 THEN '1000.00<CLIENTE_X_HORA><=2000.00'
WHEN CLIENTE_X_HORA>2000.00 AND CLIENTE_X_HORA<=3000.00 THEN '2000.00<CLIENTE_X_HORA><=3000.00'
WHEN CLIENTE_X_HORA>3000.00 AND CLIENTE_X_HORA<=4000.00 THEN '3000.00<CLIENTE_X_HORA><=4000.00'
ELSE '4000.00<CLIENTE_X_HORA'  END   INTERVAL, CLIENTE_X_HORA  FROM SGD_CAUSA)
GROUP BY INTERVAL ORDER BY TOTAL

The barchart is
The problem is when I select the last field(initial value with, per example 2000), my barchart go crazy(i believe is adding up the discarded values below 2000):

That ELSE(>6000) should be much smaller than is showing.How can I solve that?
Best Regards,
  DDias
CLARIFICATION from OP:
The query is the same as above but begins in 2000:
SELECT CASE WHEN CLIENTE_X_HORA>2000 AND CLIENTE_X_HORA<=3000.00... and ends in 6000:ELSE '6000.00<CLIENTE_X_HORA' END INTERVAL, CLIENTE_X_HORA FROM SGD_CAUSA) GROUP BY INTERVAL ORDER BY TOTAL

put the result in table form is impractical(we are talking about over 87 thousand rows) That happens always when i give an initial value different than ZERO.

A:

Your ELSE is just that. It includes everything that is not matched by specific WHENs.
So if you do not start from zero, that last column will include everything below a lowest limit in addition to greater than highest limit.
So if you do not want this behavior, do not use ELSE at all. Use WHEN CLIENTE_X_HORA > 6000.00 (or whatever your highest limit is) as the last condition.
EDIT:

In your internal query filter out (with WHERE) the values that are below the lowest limit.
Since we no longer have unneeded low range, you no longer need the HAVING clause we added and you can even go back to using ELSE.
If your lowest limit is zero, then you will be filtering everything below 0, which I assume is nothing.

Lesson: How to use SQL to group data by interval

Introduction:
In this lesson, we will learn how to use SQL to group data by interval. We will use a sample query that groups data by interval based on a numeric field called "cliente_x_hora". We will also learn how to use case statements in SQL to create intervals and count the number of rows in each interval.

Prerequisites:
Students should have a basic understanding of SQL and how to write simple queries.

Instructions:
1. Start by explaining what intervals are and why they are useful in data analysis. Use an example to illustrate the concept.
2. Introduce the sample query used in this lesson and explain the structure of the query.
3. Explain how the case statement works in SQL and how it can be used to create intervals. Provide an example of how to use a case statement to create intervals.
4. Explain how to use the group by clause in SQL to group data by interval. Provide an example of how to use the group by clause to group data by interval.
5. Explain how to use the order by clause in SQL to order the results by the total number of rows in each interval. Provide an example of how to use the order by clause to order the results by the total number of rows in each interval.
6. Finally, provide a real-world scenario where intervals can be used to group data and analyze it.

Conclusion:
In this lesson, we learned how to use SQL to group data by interval using case statements and the group by and order by clauses. We also learned how to use intervals to analyze data and make informed decisions. We can apply this skill to various scenarios in data analysis, such as analyzing customer behavior or tracking sales trends.

Contribution of a tyrosine-based motif to cellular trafficking of wild-type and truncated NPY Y(1) receptors.
The human NPY Y(1) receptor undergoes fast agonist-induced internalization via clathrin-coated pits then recycles back to the cell membrane. In an attempt to identify the molecular determinants involved in this process, we studied several C-terminal truncation mutants tagged with EFGP. In the absence of agonist, Y(1) receptors lacking the last 32 C-terminal amino acids (Y(1)Δ32) are constitutively internalized, unlike full-length Y(1) receptors. At steady state, internalized Y(1)Δ32 receptors co-localize with transferrin, a marker of early and recycling endosomes. Inhibition of constitutive internalization of Y(1)Δ32 receptors by hypertonic sucrose or by co-expression of Rab5aS34N, a dominant negative form of the small GTPase Rab5a or depletion of all three isoforms of Rab5 indicates the involvement of clathrin-coated pits. In contrast, a truncated receptor lacking the last 42 C-terminal amino acids (Y(1)Δ42) does not constitutively internalize, consistent with the possibility that there is a molecular determinant responsible for constitutive internalization located in the last 10 amino acids of Y(1)Δ32 receptors. We show that the agonist-independent internalization of Y(1)Δ32 receptors involves a tyrosine-based motif YXXΦ. The potential role of this motif in the behaviour of full-length Y(1) receptors has also been explored. Our results indicate that a C-terminal tyrosine-based motif is critical for the constitutive internalization of truncated Y(1)Δ32 receptors. We suggest that this motif is masked in full-length Y(1) receptors which do not constitutively internalize in the absence of agonist.

Lesson: Cellular Trafficking of Receptors

Introduction:
Cellular trafficking is the process by which cells transport materials and substances within themselves. One example of this is the movement of receptors on the cell surface. Receptors are proteins that bind to specific molecules and trigger a response in the cell. In this lesson, we will learn about the cellular trafficking of NPY Y(1) receptors, a type of receptor involved in various cellular processes.

Core Value:
The core value of this lesson is understanding the process of cellular trafficking and its role in the function of receptors.

Section 1: Overview of Cellular Trafficking

Topic 1: What is cellular trafficking?
Cellular trafficking is the movement of substances within cells. This process is essential for the proper functioning of cells and the organism as a whole.

Topic 2: Types of cellular trafficking
There are several types of cellular trafficking, including endocytosis, exocytosis, and recycling. These processes allow cells to take in nutrients, expel waste products, and transport materials between different parts of the cell.

Section 2: Cellular Trafficking of NPY Y(1) Receptors

Topic 1: The NPY Y(1) receptor
The NPY Y(1) receptor is a type of receptor that binds to neuropeptide Y (NPY). This receptor plays a role in various cellular processes, including metabolism, appetite regulation, and pain sensation.

Topic 2: Fast agonist-induced internalization of NPY Y(1) receptors
When NPY binds to the Y(1) receptor, it triggers a process called internalization. This means that the receptor is taken into the cell, away from the cell surface. This process is called agonist-induced internalization and is a type of endocytosis.

Topic 3: Recycling of NPY Y(1) receptors
After internalization, NPY Y(1) receptors are recycled back to the cell surface. This process is called recycling and is a type of cellular trafficking.

Section 3: Truncated NPY Y(1) Receptors

Topic 1: Truncated NPY Y(1) receptors
In some cases, the NPY Y(1) receptor may be truncated, meaning that it is shorter than normal. These truncated receptors can still bind to NPY, but they may also have different properties.

Topic 2: Constitutive internalization of truncated NPY Y(1) receptors
Truncated NPY Y(1) receptors may be more likely to undergo internalization even in the absence of agonist binding. This process is called constitutive internalization.

Section 4: Conclusion

In this lesson, we learned about the process of cellular trafficking and its role in the function of receptors like the NPY Y(1) receptor. We also learned about the importance of understanding the properties of truncated receptors and their potential impact on cellular processes. By understanding these concepts, we can better appreciate the complex nature of cellular trafficking and its role in the function of receptors and other cellular components.

Self Leadership

Self leadership is a crucial aspect of leading well. It is surprising to discover how many leaders spend so little time investing in their own leadership development. Some leaders who are “naturally” gifted seemingly get away with little or no development, while others plateau almost immediately. It is important for all leaders to realize that unless they are investing in their own development they are doomed to plateau or worse, crash!

The Principle of Self Leadership is that you should spend about 50% of your leadership time on Self Leadership. I know what you are thinking: where will I find the time? The question of whether I continue to bail water or plug the hole is perennial, but in Self Leadership the answer is always plug the hole. You must decide whether you want to be an effective leader in a progressive and ongoing manner, or whether where you are today is as effective and as far as you are willing to go.

Ever notice when traveling on an airline how the pre-flight safety lecture always involves special instruction that “in the event of an emergency” parents are to first secure their own oxygen mask before tending to any children? It is not out of lack of care for the precious children aboard any flight, it is a sober acknowledgement that without adults who are alive those children don’t stand a chance.

How much time do you spend on Self Leadership?

Long Room

The Long Room is a notable, historic room at Lord's cricket ground, in St John's Wood, London.

Described by Lawrence Booth as "the most evocative four walls in world cricket", the Long Room is situated in the Pavilion.

Function

Players walk through the Long Room on their way from the dressing rooms to the cricket field; this walk is notoriously long and complex at Lord's. On his Test debut in 1975, David Steele got lost "and ended up in the pavilion's basement toilets".

Members of MCC and their guests have free access to the room (there are windows with views of the ground) and will often greet Australian batsmen with "witticisms ... like 'See you soon'". On this point, Australian Justin Langer, described walking through the Long Room like "being bearhugged by an invisible spirit".

As a result of the Pakistan cricket spot-fixing scandal, news of which broke on the last morning of the 2010 Lord's Test match, the presentation ceremony at the end of the match (and series) was held in the Long Room, rather than on the pitch.

The Long Room has recently been made available on a private hire basis for events such as weddings and conferences.

Decor

The Long Room is lined with paintings of famous cricketers and administrators, from the 18th century to the 21st. For contemporary or overseas players to have their portrait placed here is a considerable honour and very few have been awarded this distinction. For example, only four Australian cricketers have ever been honoured in this way: Sir Donald Bradman, Keith Miller, Victor Trumper and Shane Warne, the only one of the four to have played international cricket in the last 60 years.

Lesson: Understanding Trout Fishing Regulations in Victoria

**Introduction**

Trout fishing is a popular activity in Victoria, and Fisheries Victoria has recently consulted with recreational anglers to improve trout fishing in the region. In this lesson, we will learn about the proposed changes to trout fishing regulations in lakes and rivers, and how they complement record trout stocking underway.

**Section 1: Understanding Trout Fishing Regulations**

Trout fishing regulations are rules that govern the taking of trout in Victoria's lakes and rivers. These regulations aim to protect trout populations while providing opportunities for recreational anglers to enjoy the sport. Some of the proposed changes to trout fishing regulations in Victoria include:

- A minimum size for trout in several waters, which delivers on the state government's Target One Million commitment.
- A 45-centimeter minimum size and reduced bag limit of three fish a day for Lake Toolondo.
- Changes to improve the quality of fishing in premier trout lakes, promote iconic trout streams, and create new and exciting winter fisheries in south-west Victoria.

**Section 2: Understanding the Benefits of Trout Fishing Regulations**

The proposed changes to trout fishing regulations in Victoria have several benefits for both the environment and recreational anglers. By implementing a minimum size for trout in several waters, Fisheries Victoria aims to protect smaller trout from being caught and eaten by larger fish. This helps to maintain a healthy trout population, ensuring that there are more fish for anglers to catch in the future.

Additionally, reducing the bag limit in Lake Toolondo to three fish a day encourages anglers to practice selective fishing, which helps to preserve the largest trout for future generations. Finally, creating new and exciting winter fisheries in south-west Victoria provides anglers with more opportunities to enjoy trout fishing throughout the year.

**Section 3: Applying Trout Fishing Regulations**

Understanding trout fishing regulations is important for all anglers, as it helps to ensure that we can continue to enjoy this sport for years to come. When fishing in Victoria, be sure to familiarize yourself with the current regulations and follow them carefully. This includes paying attention to minimum size limits, bag limits, and other rules that are in place to protect trout populations.

**Glossary**

- **Trout:** A species of fish that is commonly targeted by recreational anglers.
- **Regulation:** A rule or law that governs the taking of trout in Victoria's lakes and rivers.
- **Bag limit:** The maximum number of trout that an angler may keep per day.
- **Minimum size:** The smallest size that a trout may be legally kept.

**Conclusion**

By understanding the proposed changes to trout fishing regulations in Victoria, we can play an active role in protecting trout populations while enjoying this popular sport. By practicing selective fishing and following the rules, we can help to ensure that there are plenty of trout for future generations to enjoy.

Reversible protein kinase C activation in PC12 cells: effect of NGF treatment.
Although protein kinase C (PKC) is a key enzyme in the signal transduction process, there is little information on the mechanism leading to PKC activation in living cells. Using a new fluorescence imaging method, we studied this mechanism and correlated PKC conformational changes with intracellular Ca2+ concentration. PC12 cells were simultaneously loaded with Fura-2-AM and Fim-1, two fluorescent probes, which recognize Ca2+ and PKC, respectively. KCl and carbachol (an agonist to muscarinic receptors) applications induced dose-dependent increases of fluorescence for both probes. Both Ca2+ and PKC responses were observed within seconds following KCl or carbachol application, and were reversible upon stimulus withdrawal. PKC activation kinetics was slightly more rapid than the Ca2+ response after KCl application. After nerve growth factor (NGF) treatment of the cells, the amplitude of the KCl-induced PKC responses was larger indicating an increase in the activated PKC-pool in these cells. This difference between control and NGF-treated cells was not observed following carbachol application, suggesting the involvement of different PKC pools. While the Ca2+ response uniformly occurred in the cytosol, the PKC response displayed a patch pattern with higher intensities in the peripheral zone near the plasma membrane. This heterogeneous distribution of PKC activation sites was similar to the immunocytological localization of Ca2+-dependent and independent PKC isoforms, which suggested that at least several PKC isoforms interacted with intracellular elements. Upon repeated stimulation, the PKC response rapidly desensitized.

In the design of reactor core and fuel assemblies for most types of nuclear power reactors, it is important to conduct tests to characterize the thermal-hydraulic condition at which the departure from nucleate boiling (DNB) phenomenon occurs in the fuel assembly. The tests require identification of both lateral and longitudinal locations of the DNB events in a fuel assembly. The DNB phenomenon, sometimes referred to as Boiling Crisis, limits the operation margins of a particular reactor fuel design and must be well studied.
For decades, reactor component designers have used electrically heated rods as simulated nuclear fuel. The coolant for the simulated fuel bundles is water and large amounts of electricity are consumed. Other low boiling point refrigerants such as freon may be used as the simulated coolant to minimize the electrical consumption, while retaining the basic physical phenomenon. Each electrically heated rod consists of a thin wall tube of high resistivity metal, such as inconel or monel, as the heated section, an unheated upstream section, and an unheated downstream section for flow development. The unheated sections are made of a low resistivity metal, such as nickel. The rod diameter and inter-rod spacing are set to be the same as those in an actual fuel rod assembly.
In order to achieve a realistic thermal-hydraulic condition in the reactor fuel rod assembly, electrically heated rods are arranged into a configuration such as a 3.times.3, 4.times.4, 5.times.5, 6.times.6, 7.times.7 square, or other hexagonal bundles. A 5.times.5 square bundle requires a total of 25 rods. All 25 rods are commonly bused (or electrically tied together) at two electrodes, a cathode on one end and an anode on the other, to allow electric current to pass through the rod bundle. In addition to DNB studies, electrically heated rod bundles may also be used to investigate other thermal-hydraulic phenomena of a reactor core, such as multiphase instability and post-accident reflood heat transfer.
Due to longitudinal thermal expansion and potential buckling, the individual heater rods cannot be rigidly anchored to both electrodes at the same time. Normally, one end of all heater rods may be rigidly tied to a common electrode which is made of a highly conductive metal, such as nickel. The opposite ends of all rods are left free to enable expanding or sliding. As a consequence, the free expanding ends of the heater rods need to be individually connected to a braided/flexible cable. All braided cables are then joined to the other common electrode.
This approach, as traditionally practiced in most DNB or other rod bundle heat transfer test facilities to counter the buckling problem, suffers from the tedious electrical connection (and disconnection) procedure and crowded cabling, particularly when the number of rods is large. In addition, the consistency and reliability of electrical contact in this type of connection may be compromised, which can result in undesirable arcing and local fusing.
Accordingly, it is an object of this invention to provide an improved flexible electrical connection that exhibits a low resistance.
It is another object of this invention to provide an improved flexible electrical interconection that is easily configured and exhibits a consistent low resistance interconnection.

Lesson: Understanding the Departure from Nucleate Boiling (DNB) Phenomenon in Nuclear Reactors

Introduction:
The departure from nucleate boiling (DNB) phenomenon is an important factor in the design of reactor cores and fuel assemblies for most types of nuclear power reactors. It is crucial to understand the thermal-hydraulic conditions that lead to DNB because it limits the operation margins of a particular reactor fuel design. In this lesson, we will learn about the DNB phenomenon, its significance in nuclear reactors, and the methods used to study it.

I. What is the Departure from Nucleate Boiling (DNB) Phenomenon?
- DNB is a boiling crisis that occurs when the heat flux at the surface of a heated object becomes so high that it exceeds the critical heat flux (CHF).
- CHF is the maximum heat flux that a coolant can handle without causing a significant increase in temperature.
- DNB is a critical event because it marks the beginning of the transition from convective boiling to nucleate boiling, which can lead to a rapid increase in temperature and potential damage to the reactor core.

II. Why is DNB Important in Nuclear Reactors?
- DNB is significant because it affects the safety and efficiency of nuclear reactors.
- It is essential to understand the thermal-hydraulic conditions that lead to DNB so that the reactor core and fuel assemblies can be designed to prevent it from occurring.
- DNB can also impact the overall performance of the reactor, as it limits the operation margins of a particular fuel design.

III. How is DNB Studied in Nuclear Reactors?
- Researchers use various experimental techniques to study DNB in nuclear reactors.
- One common method involves using electrically heated rods as simulated nuclear fuel.
- The coolant for the simulated fuel bundles is either water or a low boiling point refrigerant such as freon.
- The electrically heated rods consist of a thin wall tube of high resistivity metal, such as inconel or monel, as the heated section, an unheated upstream section, and an unheated downstream section for flow development.
- The unheated sections are made of a low resistivity metal, such as nickel, to ensure that the heated section reaches a high temperature.
- By varying the heat flux and flow conditions, researchers can identify the lateral and longitudinal locations of DNB events in a fuel assembly.

IV. Conclusion:
Understanding the DNB phenomenon is crucial for the safe and efficient operation of nuclear reactors. By studying DNB using electrically heated rods and various experimental techniques, researchers can identify the thermal-hydraulic conditions that lead to DNB and design reactor cores and fuel assemblies to prevent it from occurring. This knowledge can also be applied to new reactor designs and problem-solving in the field of nuclear engineering.

Glossary:
- Nucleate boiling: A type of boiling where bubbles form on the heated surface and rise due to the Marangoni effect.
- Critical heat flux (CHF): The maximum heat flux that a coolant can handle without causing a significant increase in temperature.
- Departure from nucleate boiling (DNB): A boiling crisis that occurs when the heat flux at the surface of a heated object becomes so high that it exceeds the CHF.

Lesson: Introduction to Abstract Algebra

## Section 1: Theoretical Concepts

Abstract algebra is the branch of mathematics that deals with the study of algebraic structures, such as groups, rings, and fields. It is used to solve problems in various areas of mathematics and science. In this lesson, we will introduce some of the basic concepts of abstract algebra.

1. Groups: A group is a set of elements that is closed under a binary operation, which means that the operation is defined for all elements in the set. The set must also be closed under the identity element (e) and have an inverse element (a^(-1)). For example, the set of integers (Z) under addition is a group.

2. Rings: A ring is similar to a group, but it does not require the existence of an inverse element. Instead, it requires that the operation be closed under the identity element. For example, the set of integers (Z) under multiplication is a ring.

3. Fields: A field is a special kind of ring where every non-zero element has an inverse element. For example, the set of rational numbers (Q) under addition and multiplication is a field.

## Section 2: Questions and Answers

1. What is the difference between a group and a ring?
Answer: The main difference between a group and a ring is that a group requires an inverse element, while a ring does not.

2. What is the difference between a group and a field?
Answer: The main difference between a group and a field is that a field requires every non-zero element to have an inverse element, while a group only requires the identity element and its inverse.

3. How are groups, rings, and fields used in mathematics and science?
Answer: Groups, rings, and fields are used in various areas of mathematics and science, such as number theory, geometry, and physics. They provide a framework for understanding and solving complex problems.

## Section 3: Practical Examples and Real-World Scenarios

1. The set of integers (Z) under addition is an example of a group. It is used in various applications, such as computer science (e.g., hashing functions) and cryptography (e.g., public-key encryption).

2. The set of integers (Z) under multiplication is an example of a ring. It is used in various areas of mathematics and science, such as number theory and algebra.

3. The set of rational numbers (Q) under addition and multiplication is an example of a field. It is used in various areas of mathematics and science, such as calculus and physics.

## Glossary
- Group: A set of elements that is closed under a binary operation and has an identity and inverse element.
- Ring: A set of elements that is closed under a binary operation and has an identity element but not necessarily an inverse element.
- Field: A set of elements that is a ring and every non-zero element has an inverse element.

## Conclusion
In this lesson, we introduced the basic concepts of abstract algebra, including groups, rings, and fields. We also provided practical examples and real-world scenarios that demonstrate the importance of these concepts in various areas of mathematics and science. By understanding these concepts, students can develop a deeper understanding of mathematics and its applications in the real world.

I never was much of a game console nut. My video game crazes mostly played out on the PC. But I did play the Atari in the 70s, the C64 in the 80s and the NES and SNES in the early 90s, when I wrote for Nintendo mags and borrowed the hardware from my employers. The SNES was the last console I paid any attention to.

11-y-o Junior loves all kinds of video games, particularly on-line multiplayer ones like Roblox and Runescape. But he’s also installed emulator software on the PC and played a lot of old games that originally ran on machines he’s never actually seen. He’s got a Wii which allows him to download and play old Nintendo games cheaply. In fact, he’s so into the old stuff that he subscribes to Retro Gamer magazine. This is a mag where you’ll find long interviews with the people behind Spyhunter and Arkanoid. So now we’ve made an agreement to sell his disused Nintendo DS and its cartridges and put some of the money into a certain really old game console. It arrived today. It’s a SNES made in 1994.

Junior can get all the games he likes for this machine for free over the net and play them on the PC with an emulator. But somehow he feels that running real cartridges on a real SNES makes for a better experience. So tonight it’s been Super Mario World for him.

Do you remember Intellivision? My dad thought ATARI was too much fun, that we’d never go outside. So he compromised and bought Intellivison. Nobody ever wanted to play baseball with me, so I had to play both teams at the same time, which added fun to an otherwise slow game. I could’ve played against the machine, but I always lost and there’s no fun if you KNOW you’re going to lose all three innings before you even go up to bat. Hey, I was really young, and it was a little demoralizing. But I did like the card games – got really good at black jack. It’s a wonder I didn’t end up with a gambling addiciton…. Nintendo DS released NAMCO Museum, where you have PacMan, Galaga, Xevious, etc… Fun, but annoying to use the up-down side-to-side keys – joysticks are way better. Those games got me all stressed out too – they play so quickly and I’m a slow, smell-the-roses kinda gal. I’m such an old lady! So, I’m playing logic puzzles and the likes instead. Trying to keep the cranial muscle in shape, while the rest of me falls apart… 😉

Oh yes, I forgot about the Intellivision. My friend Göran had it, must have been around 1981, 82 maybe? We played the aquarium game and Treasure of Tarmin and tennis and, I believe, Burgertime. The controls had these plastic covers that slid into place to tell you what the buttons would do for each game, and they quickly wore out.

Lesson: Introduction to Emulators and Retro Gaming

## Section 1: Theory

An emulator is a software program that allows a computer or a video game console to imitate another computer or video game console's behavior. This means that you can use an emulator to play games that were designed for a different system on your own computer or video game console. Retro gaming refers to playing old video games from previous generations of consoles and computers.

## Section 2: Practice

1. What is an emulator?
   - An emulator is a software program that allows a computer or a video game console to imitate another computer or video game console's behavior.

2. Why do people use emulators?
   - People use emulators to play games that were designed for a different system on their own computer or video game console.

3. What is retro gaming?
   - Retro gaming refers to playing old video games from previous generations of consoles and computers.

4. How do emulators work?
   - Emulators work by translating the code of the original game and adjusting the graphics and sound to match the target system.

5. What are some popular emulators?
   - Some popular emulators include Nestopia, VisualBoyAdvance, and Dolphin.

## Section 3: Practical Examples

Let's say you want to play a game that was originally released on the Super Nintendo Entertainment System (SNES) but you only have a PlayStation 4. You could use an emulator like SNES9X to play the game on your PS4. The emulator will translate the code of the original SNES game and adjust the graphics and sound to match the PS4's capabilities.

Alternatively, let's say you have an old SNES console lying around but you don't have any games for it. You could use an emulator on your computer to play games from other systems, like the Sega Genesis or the Nintendo 64. This would allow you to play games from multiple systems on one device.

Glossary:
- Emulator: A software program that allows a computer or a video game console to imitate another computer or video game console's behavior.
- Retro gaming: Playing old video games from previous generations of consoles and computers.

Conclusion:
Emulators and retro gaming offer a fun way to play old games on new systems. By understanding how emulators work and the benefits of retro gaming, you can enjoy classic games from multiple systems on one device.

(a) Field of the Invention
A conductive ink composition, a method for manufacturing the same, and a method for manufacturing a conductive thin film using the same are provided.
(b) Description of the Related Art
In the existing semiconductor process, a circuit board is a board wherein a circuit pattern for electrically connecting a circuit device is formed on an insulation substrate formed of bakelite or synthetic resin, and the manufacturing method is largely divided into a subtractive method and an additive method.
The subtractive method is a method of removing parts excluding a required circuit pattern by etching and the like after wholly forming a conductive thin film on a substrate, and the additive method is a method of directly forming a circuit pattern on a substrate by plating or printing.
At present, most circuit boards are manufactured by etching, which is a representative subtractive method. According to the etching, a copper foil is laminated on an insulation substrate to form a laminate, an acid resistant material (resist) is coated only on a part corresponding to a circuit pattern on the surface of the laminate, and then parts other than the circuit pattern are dissolved to remove them, thereby forming a circuit pattern.
However, when a circuit board is manufactured by etching, since a complicated processes including formation of a laminate, resist coating, resist etching and washing, and the like should be conducted, a lot of time is consumed for the manufacturing process and production cost may increase.
Further, a discharged solution generated during the manufacturing process causes environmental problems, and to prevent this, treatment such as neutralization and the like is essentially involved, which also causes a cost increase.
The additive method is an alternative for solving the drawbacks of the circuit board manufacturing process by etching, and is a method of directly printing conductive ink on a substrate by printing such as inket printing to embody a circuit pattern, thus easily and inexpensively manufacturing a circuit board.
Since the additive method may print with a desired thickness at desired position, simplify the manufacturing process, reduce production cost, and does not cause environmental problems, the application range is being broadened.
In the additive method, ink sintering may be largely divided into heat sintering and laser sintering.
However, since commercially available heat sintering and laser sintering methods require high energy and a long sintering time, problems such as cost increase are raised.
Accordingly, the inventors studied a conductive ink composition suitable for an additive method (e.g., inket printing method), a manufacturing method of the same, and a method for effectively sintering a pattern formed using the ink.

Lesson: Introduction to Solar Pool Heating
## I. Theoretical Concepts
Solar pool heating is a method of heating a swimming pool using energy from the sun. This method is becoming increasingly popular as people look for ways to reduce their energy bills and carbon footprint. In this lesson, we will explore the benefits of solar pool heating, how it works, and how to calculate its efficiency.
## II. Practical Examples
To understand how solar pool heating works, let's consider a simple example. Suppose we have a swimming pool that measures 20 feet by 40 feet and has a depth of 6 feet. The pool is surrounded by a solar collector that absorbs energy from the sun and transfers it to the pool water. The collector is designed to capture as much sunlight as possible and convert it into heat.
Let's assume that the collector is 100% efficient, meaning that it captures all the sunlight that falls on it. We will also assume that the collector is facing south, which is the best direction for maximum sunlight exposure. Finally, we will assume that the pool is covered with a solar blanket when not in use, which helps to retain the heat.
Using these assumptions, we can calculate the efficiency of the solar pool heating system. First, we need to determine the amount of energy that the collector can capture. We can do this by multiplying the area of the collector by the amount of sunlight that falls on it.
Area of collector = 20 ft x 40 ft = 800 square feet
Assuming an average of 4 hours of sunlight per day, the collector captures 4 x 365 x 800 = 1,168,000 kWh of energy per year.
Now, let's assume that the pool loses 5 degrees Fahrenheit per night. To maintain a comfortable temperature, we need to add enough heat to offset this loss. Assuming that we want the pool to be 78 degrees Fahrenheit during the day, we need to add enough heat to raise the temperature from 73 degrees Fahrenheit (the temperature after accounting for the overnight loss) to 78 degrees Fahrenheit.
This means that we need to add 5 degrees Fahrenheit x 24 hours = 120 degrees Fahrenheit of heat per day. Since there are 365 days in a year, we need to add 120 x 365 = 43,800 BTUs of heat per year.
Using the efficiency of the collector, we can calculate the amount of energy that we need to add to the pool. Assuming a coefficient of performance (COP) of 2.0 for the collector, we need to add 2.0 x 43,800 = 87,600 BTUs of energy from another source.
## III. Practical Examples
In practice, the efficiency of a solar pool heating system is typically lower than 100%. This means that we need to add more energy to the pool than the collector captures. However, even with this additional energy, solar pool heating can still save money on pool heating costs.
For example, suppose that we have a pool that measures 20 feet by 40 feet and has a depth of 6 feet. The pool is surrounded by a solar collector that absorbs energy from the sun and transfers it to the pool water. The collector is designed to capture as much sunlight as possible and convert it into heat.
Let's assume that the collector is 90% efficient, meaning that it captures 90% of the sunlight that falls on it. We will also assume that the collector is facing south, which is the best direction for maximum sunlight exposure. Finally, we will assume that the pool is covered with a solar blanket when not in use, which helps to retain the heat.
Using these assumptions, we can calculate the efficiency of the solar pool heating system. First, we need to determine the amount of energy that the collector can capture. We can do this by multiplying the area of the collector by the amount of sunlight that falls on it.
Area of collector = 20 ft x 40 ft = 800 square feet
Assuming an average of 4 hours of sunlight per day, the collector captures 4 x 365 x 800 = 1,168,000 kWh of energy per year.
Now, let's assume that the pool loses 5 degrees Fahrenheit per night. To maintain a comfortable temperature, we need to add enough heat to offset this loss. Assuming that we want the pool to be 78 degrees Fahrenheit during the day, we need to add enough heat to raise the temperature from 73 degrees Fahrenheit (the temperature after accounting for the overnight loss) to 78 degrees Fahrenheit.
This means that we need to add 5 degrees Fahrenheit x 24 hours = 120 degrees Fahrenheit of heat per day. Since there are 365 days in a year, we need to add 120 x 365 = 43,800 BTUs of heat per year.
Using the efficiency of the collector, we can calculate the amount of energy that we need to add to the pool. Assuming a coefficient of performance (COP) of 2.0 for the collector, we need to add 2.0 x 43,800 = 87,600 BTUs of energy from another source.
## IV. Glossary
- Solar Collector: A device that captures energy from the sun and converts it into heat.
- Coefficient of Performance (COP): A measure of how efficiently a solar collector captures energy from the sun.
- BTU: British thermal unit, a measure of heat energy.
## V. Conclusion
Solar pool heating can be an effective way to reduce pool heating costs. By capturing energy from the sun and converting it into heat, a solar collector can help to maintain a comfortable pool temperature while reducing energy bills. In this lesson, we explored the benefits of solar pool heating, how it works, and how to calculate its efficiency. By understanding the basic principles of solar pool heating, we can make informed decisions about whether it is right for us and how to maximize its benefits.
