Reflex cardiovascular response to brief abdominal visceral ischemia is mediated in part by prostaglandins.
Prostaglandin concentrations are elevated in intestinal lymph during brief abdominal visceral ischemia, and exogenously applied prostaglandins can directly stimulate or sensitize ischemically sensitive visceral sympathetic nerve fibers. However, it is not known if prostaglandin production during abdominal ischemia is sufficient to contribute to the reflex cardiovascular response (e.g., hypertension). Accordingly, in anesthetized cats, the femoral artery was cannulated for measurement of arterial blood pressure, and the superior mesenteric and celiac arteries were isolated and fitted with snare occluders. After dual occlusion of these arteries (</=20 min), the cyclooxygenase inhibitors indomethacin (10-20 mg/kg iv, n = 5, group 1) or acetylsalicylic acid [50 mg/kg iv (n = 6) and ia (n = 2); group 2] were administered and ischemia was repeated. In group 1, indomethacin lowered the reflex arterial blood pressure increment by 39% from 31 +/- 7 to 19 +/- 5 mmHg (P > 0.05). In group 2, acetylsalicylic acid significantly (P < 0.05) reduced the reflex rise in blood pressure by 46% (28 +/- 3 to 15 +/- 4 mmHg). A second, more invasive preparation (group 3) was utilized to 1) minimize the confounding, transient, nonreflex rise in blood pressure associated with arterial ligation, and 2) further assess the inhibitory effect of indomethacin. In group 3, the ischemia-induced blood pressure rise of 28 +/- 6 mmHg was reduced by 43% to 16 +/- 4 mmHg after indomethacin (n = 4, P < 0.05). Thus blockade of the cyclooxygenase pathway by two structurally dissimilar inhibitors attenuated the visceral-cardiovascular reflex response to brief ischemia, suggesting that prostaglandins released during visceral ischemia contribute significantly to the activation of the reflex cardiovascular response.

Lesson: Understanding Prostaglandins and Their Role in Reflex Cardiovascular Response

Introduction:
Prostaglandins are hormone-like substances that play a crucial role in various physiological processes in the body. They are involved in the regulation of blood pressure, inflammation, and pain. In this lesson, we will learn about prostaglandins and their role in the reflex cardiovascular response to brief abdominal visceral ischemia.

Section 1: What are Prostaglandins?
Prostaglandins are chemical messengers that are produced by the enzyme cyclooxygenase (COX) from arachidonic acid. They have various functions in the body, including regulating blood pressure, inflammation, and pain.

Section 2: Role of Prostaglandins in Reflex Cardiovascular Response
During abdominal ischemia, the production of prostaglandins is increased in the intestinal lymph. These prostaglandins can directly stimulate or sensitize ischemically sensitive visceral sympathetic nerve fibers, which are responsible for the reflex cardiovascular response.

Section 3: How do Prostaglandins affect Blood Pressure?
Prostaglandins play a crucial role in regulating blood pressure by acting on the blood vessels. They cause the blood vessels to dilate, which lowers blood pressure. However, during abdominal ischemia, the production of prostaglandins is increased, and they can also stimulate the release of norepinephrine from the postganglionic sympathetic nerve endings. Norepinephrine causes the blood vessels to constrict, which increases blood pressure.

Section 4: Experimental Evidence
In an experiment, researchers used anesthetized cats and isolated the superior mesenteric and celiac arteries with snare occluders. They then induced ischemia by occluding these arteries for a short period (20 minutes or less). They found that the administration of cyclooxygenase inhibitors, such as indomethacin and acetylsalicylic acid, reduced the production of prostaglandins and prevented the release of norepinephrine from the postganglionic sympathetic nerve endings. This prevented the increase in blood pressure that would normally occur during abdominal ischemia.

Conclusion:
In conclusion, prostaglandins play a crucial role in the reflex cardiovascular response to brief abdominal visceral ischemia. They can directly stimulate or sensitize ischemically sensitive visceral sympathetic nerve fibers and contribute to the increase in blood pressure. However, the production of prostaglandins during abdominal ischemia can be reduced by administering cyclooxygenase inhibitors, which can prevent the increase in blood pressure. This knowledge can be applied to develop new treatments for conditions related to abdominal ischemia, such as shock and organ failure.

text: Discussion in 'PS2' started by chuj666, Feb 12, 2003.. Does this really work? and can i play backups of Pal format Ps2 games?. From what I have heard, any mod that does not require direct soldering will have trouble reading 80 minute/700mb cd's. This means 90% of DVD rips will not work. I'm not too sure what the score is in regards to DVD backups though.. Chuj666,. I had to No-Solder Mod and it only played CD backups. DVD backups would not work. Even bought AR2/GS2 & Swap Magic2 they didn't help. Gave in and bought Magic3.1 and PS2 works great and plays all PS1 & Ps2 originals and backups.. Separate names with a comma.

Lesson: Introduction to Diagnostic Tests

## Section 1: Theoretical Concepts

Diagnostic tests are medical tests that help identify diseases or conditions by analyzing samples such as blood, urine, or tissue. These tests can detect the presence or absence of a particular disease or condition, measure the severity of the disease, or monitor the effectiveness of a treatment.

## Section 2: Questions and Answers

1. What are diagnostic tests used for?
Answer: Diagnostic tests are used to identify diseases or conditions by analyzing samples such as blood, urine, or tissue.

2. How do diagnostic tests work?
Answer: Diagnostic tests work by analyzing samples taken from the body to detect the presence or absence of a particular disease or condition, measure the severity of the disease, or monitor the effectiveness of a treatment.

3. What types of samples are used in diagnostic tests?
Answer: Diagnostic tests can use various types of samples, including blood, urine, tissue, or other bodily fluids.

4. Are diagnostic tests always accurate?
Answer: No, diagnostic tests are not always accurate. The accuracy of a test depends on various factors, including the quality of the sample, the test itself, and the skill of the person performing the test.

5. Can diagnostic tests detect all diseases or conditions?
Answer: No, diagnostic tests cannot detect all diseases or conditions. Some diseases or conditions may not have any known tests, while others may have tests that are not very accurate.

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

Let's consider a hypothetical patient named John who has been experiencing fatigue, weight loss, and night sweats. His doctor suspects that he may have diabetes and recommends a diagnostic test called a fasting plasma glucose test (FPG) to check his blood sugar levels.

The FPG test involves taking a blood sample after John has fasted for at least eight hours. The sample is then analyzed to determine his blood sugar level. If John's blood sugar level is above 126 mg/dL, it indicates that he has diabetes.

In this scenario, the diagnostic test helps confirm whether John has diabetes or not. If the test result is positive, it means that John needs to start treatment immediately to manage his blood sugar levels and prevent complications such as heart disease, kidney disease, and nerve damage.

## Glossary
- Diagnostic tests: Medical tests that help identify diseases or conditions by analyzing samples such as blood, urine, or tissue.
- Samples: Body fluids or tissues taken from a person for diagnostic tests.
- Accuracy: The degree of correctness of a diagnostic test.
- Disease or condition: A state of health that is abnormal or undesirable.

Lesson: Introduction to Plumbing

## Section 1: Theoretical Concepts

Plumbing is the system of pipes, valves, and fixtures that move water from a source to a location where it can be used or disposed of. It involves the installation, maintenance, and repair of these systems in buildings and homes.

## Section 2: Practical Examples

A common example of plumbing is a toilet. When you flush the toilet, water flows through the pipes and into the sewage system. Another example is a shower, where hot water is delivered to the showerhead and then drained away.

## Section 3: Real-World Scenarios

In this section, we will explore some real-world scenarios where plumbing is essential. One such scenario is a flooded bathroom. If the drain becomes clogged, water can back up into the bathtub or shower, causing a flood. In this case, a plumber would need to come out and unclog the drain using a snake or other tool.

Another scenario is a leaky faucet. A small leak may not seem like a big deal, but over time, it can waste a significant amount of water. A plumber can fix the leak by replacing the washer or other parts of the faucet.

## Glossary

- Plumbing: A system of pipes, valves, and fixtures that move water from a source to a location where it can be used or disposed of.
- Pipe: A tube used to transport fluids, such as water, from one location to another.
- Valve: A device that regulates the flow of a fluid, such as water, by opening, closing, or partially obstructing the passageway.
- Fixture: A plumbing component, such as a sink or toilet, that is permanently attached to a building and used for a specific purpose.
- Sewage system: A network of pipes and channels that transport wastewater from buildings to a treatment plant or other disposal site.

## Conclusion

Plumbing is an essential part of our daily lives, and understanding how it works can help us maintain our homes and prevent costly repairs. By learning about the theoretical concepts, practical examples, and real-world scenarios of plumbing, we can become more knowledgeable about this important field.

JOSEPH NYE, an American political scientist, first coined the term “soft power” in 1990. It describes the ability to coax and persuade others, rather than coerce them. For countries, it is a way to spread influence subtly without the use of armies, sanctions or other forceful techniques.

By its nature, soft power is far harder to measure than the size and effectiveness of standing armies. In an attempt to put firm numbers to the concept, Portland, a London-based PR firm, and the University of Southern California’s Center on Public Diplomacy have created an index of soft power, the most recent update of which was released today. It is made up of two parts: 30% is based on polling data on countries’ reputations abroad; the remainder relies on concrete statistics on variables such as diplomatic missions abroad, government foreign-aid budgets, memberships of multilateral organisations and so on. Changes in the 30-country ranking, which has been running for three years, seem to show that a countryʼs perceived openness is linked to its clout abroad.

France is a prime example. In 2016 it placed fifth, whereas this year it took the top spot. This surge seems largely due to the election of Emmanuel Macron as president in May and the success of his party, La République en Marche!, in the subsequent parliamentary election in June. His pro-Europe and pro-business policies have boosted his countryʼs standing internationally.

In contrast, Britain and Americaʼs shifts towards inward-looking politics have taken a bite out of their soft power. For both countries, the slide down the rankings was caused by a drop in their reputations overseas as measured by polls included in the index. Donald Trumpʼs “America first” agenda, though only in its early stages, has spooked allies and weakened ties with the rest of the world. America fell from first to third in this yearʼs ranking. Britain slipped from the top spot in 2015 to second last year, which may have been a result of the country’s decision to vote to leave the European Union. It would probably have wound up on the bronze podium this year, had the United States not done even more than Britain did to lose friends abroad.

One country, however, has seen a perceptible change in its soft power without a dramatic change in its politics. In 2015 China ranked last among the 30 countries in the index; this year it has climbed up to 25th place. This gain was due to small improvements across a range of categories, like cultural potency and diplomatic relations with other states. And it is no accident: a decade ago its Communist Party officially made developing soft power a priority. The government now spends roughly $10bn each year on this objective, according to David Shambaugh of George Washington University. That is more than the expenditure of Britain, France, Germany, Japan and the United States combined. Whoever said money can’t buy you love should have a word with the powers that be in Beijing.

Lesson: Soft Power

Introduction:

Soft power refers to the ability of a country or individual to influence others without using force, coercion, or economic incentives. It involves using cultural, ideological, and political means to persuade others to follow a particular course of action. In this lesson, we will explore the concept of soft power, its importance, and how it can be used effectively.

Core Value:

The core value of soft power is that it provides an alternative to traditional forms of power such as military might or economic coercion. It allows countries to achieve their objectives without resorting to force or coercion, which can often lead to negative consequences.

Section 1: Understanding Soft Power

Question: What is soft power?

Answer: Soft power is the ability to influence others through cultural, ideological, and political means without using force, coercion, or economic incentives.

Question: Why is soft power important?

Answer: Soft power is important because it provides an alternative to traditional forms of power such as military might or economic coercion. It allows countries to achieve their objectives without resorting to force or coercion, which can often lead to negative consequences.

Question: How can soft power be used effectively?

Answer: Soft power can be used effectively by promoting a country's values, culture, and political ideals. This can be done through diplomacy, international aid, cultural exchanges, and public diplomacy.

Section 2: Measuring Soft Power

Question: How is soft power measured?

Answer: Soft power is measured using a combination of polling data on countries' reputations abroad and concrete statistics on variables such as diplomatic missions abroad, government foreign-aid budgets, memberships of multilateral organizations, and so on.

Question: What are some examples of concrete statistics used to measure soft power?

Answer: Some examples of concrete statistics used to measure soft power include diplomatic missions abroad, government foreign-aid budgets, memberships of multilateral organizations, and cultural exchange programs.

Section 3: Examples of Soft Power

Question: How has France's soft power increased?

Answer: France's soft power has increased due to its perceived openness and its promotion of values such as freedom, democracy, and human rights. This has been achieved through diplomacy, cultural exchanges, and public diplomacy initiatives.

Question: Can soft power be used to counteract negative perceptions of a country?

Answer: Yes, soft power can be used to counteract negative perceptions of a country. For example, a country may work to improve its human rights record, promote its cultural heritage, and engage in public diplomacy initiatives to improve its reputation abroad.

Conclusion:

In conclusion, soft power is an important tool for countries to influence others without resorting to force or coercion. By understanding the concept of soft power, measuring its effectiveness, and using it effectively, countries can achieve their objectives while maintaining positive relationships with other nations.

textbook:
This is an example of a Lex program that reads in ML code and outputs pretty-printed versions of the code. The Lex program uses regular expressions to identify different types of tokens in the input code, such as numbers, keywords, and strings. It also includes functions to handle comments and whitespace in the input code.

Lex programs are often used in compilers to tokenize input code before it is passed on to the parser. Tokenization involves breaking down the input code into smaller units called tokens, which can then be processed by the parser. In this case, the Lex program generates a list of Lex_Result objects, which represent the tokens in the input code.

The main function of the Lex program is make_string, which concatenates all the elements of the char_list list in reverse order. This is used to handle comments in the input code. The tab and expand_tab functions are used to handle indentation in the input code.

Overall, this Lex program demonstrates how regular expressions can be used to tokenize input code and how functions can be defined to handle specific syntax elements, such as comments and indentation.


text: To the Editor: Dr Nauman and colleagues1 presented data from a large Norwegian cohort studied twice 10 years apart (Nord-Trøndelag County Health Study [HUNT-1 and HUNT-2]) on the association of changes in resting heart rate (RHR) with mortality from ischemic heart disease. The authors found that the association was not linear and that a decrease in RHR at the second measurement showed no mortality benefit. This finding is at variance with previous results by others who showed that a RHR decrease during 5 years of observation was associated with a decreased risk for mortality of.

Lesson: Understanding Heart Rate and Mortality

Introduction:
In this lesson, we will explore the relationship between heart rate and mortality rates. We will learn about the different types of heart rates, how they are measured, and what factors can affect them. We will also discuss how changes in heart rate can impact a person's risk of death from ischemic heart disease.

Section 1: Understanding Heart Rates

Topic 1: Types of Heart Rates
- Resting heart rate (RHR): The number of times the heart beats per minute while at rest.
- Exercise heart rate: The number of times the heart beats per minute during physical activity.
- Average heart rate: The average number of times the heart beats per minute over a 24-hour period.

Topic 2: Measuring Heart Rates
- A stethoscope is used to listen to the sounds of the heart and count the number of beats per minute.
- A heart rate monitor is a device that measures the heart rate electronically.

Topic 3: Factors Affecting Heart Rates
- Age
- Fitness level
- Stress and anxiety
- Medications
- Medical conditions

Section 2: Changes in Heart Rate and Mortality Rates

Topic 1: The Relationship Between Heart Rate and Mortality
- Studies have shown that a lower resting heart rate is associated with a lower risk of death from ischemic heart disease.
- However, not all studies agree on this relationship.

Topic 2: The Nord-Trøndelag County Health Study
- Researchers studied a group of people in Norway over a 10-year period.
- They found that a decrease in resting heart rate was not associated with a decreased risk of death from ischemic heart disease.
- This finding is different from other studies that have shown a decrease in resting heart rate is associated with a lower risk of death.

Section 3: Critical Thinking Questions

1. Why do you think some studies show a relationship between a lower resting heart rate and a lower risk of death from ischemic heart disease, while others do not?
2. What factors could explain the differences in the results of the Nord-Trøndelag County Health Study compared to other studies?

Glossary:
- Ischemic heart disease: A type of heart disease caused by narrowed or blocked blood vessels that can lead to chest pain or heart attack.

Conclusion:
In this lesson, we learned about the different types of heart rates and how they are measured. We also explored the relationship between changes in heart rate and mortality rates. We discussed the findings of the Nord-Trøndelag County Health Study and considered possible reasons for the differences in the results compared to other studies. Finally, we engaged in critical thinking questions to further our understanding of this topic. By applying these concepts, we can better understand the importance of heart health and how it relates to our overall well-being.

Lesson: The Importance of Asking Questions in Engineering Design

**Introduction**
In this lesson, we will learn about the importance of asking questions in engineering design. We will use the example of Matrix Fitness, a company that designs and manufactures exercise equipment, including training cycles for cycling classes.

**Theory**
Engineering design is the process of creating a product or system that meets certain criteria or specifications. This involves identifying user needs, analyzing constraints, and developing a solution that is efficient, effective, and elegant. Asking questions is an essential part of this process, as it helps engineers to understand the problem they are trying to solve and identify potential solutions.

**Practice**
Matrix Fitness has designed a line of training cycles that appeal to a wide range of users. To achieve this, they asked questions such as:

1. What types of cyclists are there?

Supply chain management is the process of managing the flow of goods and services from the supplier to the end consumer. It involves coordinating and optimizing all aspects of the supply chain, including procurement, production, distribution, and delivery.

### Section 2: Practical Examples
Let's take the example of a company that produces and sells smartphones. The supply chain starts with the procurement of raw materials such as metals and plastics from suppliers. These materials are then used in the production process, where the smartphones are assembled and tested. Once the phones are ready, they are distributed to retail stores and eventually sold to customers. The entire process is managed by the supply chain team, who ensure that the products reach the customers in a timely and efficient manner.

### Section 3: Real-World Scenarios
One real-world scenario where supply chain management plays a crucial role is in the automotive industry. Car manufacturers rely on a complex network of suppliers to provide them with parts and components. The supply chain team must ensure that these parts are delivered on time and meet the quality standards of the manufacturer. Any disruption in the supply chain can lead to delays in production and ultimately affect the sales and reputation of the company.

New Delhi, Sep 20 () India's biggest digital payments company Paytm has flagged concerns over rival Google Pay's privacy policy, saying it allows collection and disclosure of users' personal data with group companies. The Alibaba and SoftBank-backed company also alleged that Google's privacy policy allows the American giant to utilise a user's personal data for advertising and promotional purposes, without any additional consent from the user. "This is a clear disregard for a consumer's need for privacy," Paytm said in a recent letter to the National Payments Corporation of India (NPCI). As the battle to capture market share in the booming Indian digital payments space intensifies, One97 Communications owned-Paytm has alleged violation of basic privacy norms in the tech titan's policy. In its two-page letter, Paytm said Google Pay's privacy policy allows it to access user's navigation, logs and correspondence data while also reserving the right to collect, store, use and read user's communication. When contacted, a Google spokesperson said the company does not use any individual UPI transactions data for any monetisation purpose, including advertisements. "Google Pay shares user data as may be required for the purpose of processing transactions or providing Google Pay Services with our authorised partners... Sharing of this information is in accordance with the applicable laws and requisite consent obtained from the user and in conformity with standard industry practice," the spokesperson said. These partners, the spokesperson said, include banks, banks on UPI infrastructure, bill aggregators, merchants on the Google Pay for Business programme and others with whom the user transacts. Interestingly, Google and Paytm have taken contrarian views on the data localisation issue. While Paytm has been in favour of storing and processing critical data like payments within India, Google's stance has been to allow free flow of data. "...Google Pay...has the scope of using their customer's data for their monetary gains with complete disregard of the user's need for privacy," Paytm argued. It alleged that critical payments data collected by Google "is being processed and stored outside of India which can have severe security implications in case of a data breach as their policy states that this data is also being disclosed with advertisers and third parties". It hoped that NPCI "would re-visit the payments policy of Google Pay for India". A copy of the letter has also been marked to IT Secretary, Ajay Sawhney. Paytm has also written to industry body IAMAI emphasising its stance that India has taken a bold step in strengthening data sovereignty through dynamic measures like data localisation. It has asked the Internet and Mobile Association of India (IAMAI) to incorporate Paytm's views in the final submission to IT Ministry on the draft Personal Data Protection Bill. SR MBI ANZ ABM

Establishment and characterization of human glioblastoma cell line (HUBT-n).
We succeeded in primary culture of 3 in 4 cases of glioblastomas. The long-term passage cultures were not done from the primary cultures of original tumor, but glioblastoma cell line (HUBT-n) was established from a xenograft of nude mouse. This line grew well without interruption for 4 years and was subcultivated over 120 times. The cells were spindle like or round in shape and neoplastic and pleomorphic features contained glial fibrillar acid protein (GFAP) and S-100 protein and grew multilayering without contact inhibition. A bough-shaped long projection was noted from a small cell. One of the characteristics of the HUBT-n cells was existence of well developed intermediate filaments in their cytoplasm. The cells proliferated rapidly, and the population doubling time was about 32 hours. The chromosome number showed a narrow distribution of diploid range. Abnormal constitution was observed in all cells by G-band karyotyping. The culture cells were easily transplanted into the subcutis of nude mouse and produced the tumor resembling the original tumor.

Lesson: Introduction to Cell Lines in Biology

### Overview

In biology, cell lines are essential tools used for research and experimentation. In this lesson, we will explore the process of establishing and characterizing cell lines, with a focus on the establishment of the human glioblastoma cell line (HUBT-n).

### Learning Objectives

By the end of this lesson, students will be able to:

1. Understand the importance of cell lines in biological research.
2. Explain the process of establishing and characterizing cell lines.
3. Describe the steps involved in the establishment of the human glioblastoma cell line (HUBT-n).
4. Analyze the properties and characteristics of the HUBT-n cell line.
5. Apply critical thinking skills to understand the significance of the HUBT-n cell line in biological research.

### Section 1: Introduction to Cell Lines

Cell lines are a group of cells that are derived from a single parent cell and have the same genetic makeup. They are used in research to study various biological processes, such as cell growth, differentiation, and response to drugs. Cell lines can be derived from various sources, including animals, plants, and humans.

### Section 2: Establishing and Characterizing Cell Lines

The process of establishing and characterizing cell lines involves several steps, including:

1. Obtaining a sample of tissue or cells from the source organism.
2. Culturing the cells in a suitable medium under controlled conditions.
3. Passaging the cells through multiple generations to maintain their characteristics.
4. Characterizing the cells based on their morphology, growth rate, and other properties.
5. Testing the cells for any abnormalities, such as chromosomal aberrations or mutations.

### Section 3: Establishment of the HUBT-n Cell Line

The HUBT-n cell line was established from a glioblastoma tumor sample obtained from a patient. The following steps were taken to establish this cell line:

1. Primary culture: The tumor sample was cultured in a suitable medium, and the cells were allowed to grow and multiply.
2. Xenograft in nude mice: The primary culture was implanted into nude mice, which served as a host for the tumor cells.
3. Long-term passage: The xenografted cells were passaged multiple times to maintain their characteristics and ensure their growth.
4. Characterization: The HUBT-n cell line was characterized based on its morphology, growth rate, and other properties.

### Section 4: Properties and Characteristics of the HUBT-n Cell Line

The HUBT-n cell line exhibits several properties and characteristics, including:

1. Rapid growth rate: The HUBT-n cells divide rapidly, with a population doubling time of about 32 hours.
2. Diploid chromosome number: The cells have a normal chromosome number, indicating no abnormalities in their genetic makeup.
3. Presence of intermediate filaments: The cells contain well-developed intermediate filaments in their cytoplasm.
4. Positive for glial fibrillar acid protein (GFAP) and S-100 protein: The cells express markers specific to glioblastoma cells.
5. Multilayering growth: The cells grow in a multilayered pattern without contact inhibition.

### Section 5: Significance of the HUBT-n Cell Line in Biological Research

The HUBT-n cell line is significant in biological research due to its unique properties and characteristics. It serves as a valuable tool for studying glioblastoma, a type of brain cancer that is difficult to treat. Researchers can use the HUBT-n cell line to investigate the molecular mechanisms underlying glioblastoma development, test potential therapeutic agents, and study the effects of various factors on cell growth and survival.

### Conclusion

In this lesson, we explored the process of establishing and characterizing cell lines, with a focus on the HUBT-n cell line. We learned about the importance of cell lines in biological research and the steps involved in establishing a cell line. We also analyzed the properties and characteristics of the HUBT-n cell line and discussed its significance in biological research. By understanding these concepts, students can apply their knowledge to analyze and interpret research findings in the field of cell biology.

James V. Carroll, III, Houston, Tex., Andrews, Kurth, Campbell & Jones, Houston, Tex., for respondent.
Before WISDOM, COLEMAN and SIMPSON, Circuit Judges.
PER CURIAM:

1
This case comes before us on application from the National Labor Relations Board (Board) for enforcement of its determination that the respondent, Offenhauser Company, (company) violated Section 8(a)(5) and (1) of the National Labor Relations Act by refusing to recognize and bargain with the Union1 as the certified representative of its employees in an appropriate bargaining unit.2  We enforce the Board's decision and order.

2
On August 30, 1968, pursuant to a Stipulation for Certification Upon Consent Election, the Regional Director for the Board's Twenty-third Region conducted a secret ballot election among the Company's employees in an agreed upon unit.  Of approximately 106 eligible voters, 52 voted for and 43 voted against the Union.  Shortly thereafter the Company filed timely objections to the Union's conduct which it claimed affected the outcome of the election.  In summary, the Company asserted:

3
1.  The Union through its agents committed acts of coercion and made threats against Offenhauser Company employees for the purpose of influencing votes.

4
2.  The Union grossly misrepresented the Company's recent profits and ability to provide higher wages and benefits for its employees for the purpose of influencing votes.

5
3.  The Union slandered and falsely discredited Wall Street Journal reports regarding union activities which were posted by the Company.

6
4.  At its last meeting prior to the election, the Union through its agents stated that a perfectly legitimate message contained in a Company paper was illegal and that if the Company won the election the Union would have the election reversed based on the language contained in said letter.

7
5.  The Union, falsely and for the wrongful purpose of influencing votes, made a statement in its final letter to the employees that 'all of the employees in your shop' can attend a special meeting and vote on whether or not a strike vote will be called and that two-thirds of such employees would determine whether a strike would be called.

8
6.  The Union appointed an observer in the election and allowed him to vote (unknown to the Company) although he had quit and taken full-time employment at another company.

9
7.  The Union influenced votes by promising and giving payment for Union Support in the election.

10
On October 30, 1968, the Regional Director ordered that a hearing be held on the objections before a hearing officer, and on November 14, 1968, a hearing was held.  On December 16, 1968, the hearing officer issued his report recommending that all of the Company's objections be overruled.  The Board subsequently adopted the hearing officer's recommendations, and on March 3, 1969, entered the appropriate certificate of representation.  On June 13, 1969, the unfair labor practice charge was filed, and the General Counsel moved for summary judgment on October 10, 1969.  After the filing of opposing briefs the Board entered its summary order on December 16, 1969, finding the Company guilty of an unfair labor practice.

11
Without discussing each of the Company's objections, we find substantial support in the record for the Board's finding that the Company has not shown sufficient evidence to require the setting aside of the election.  Since we find that the Board properly certified the Union, and since the Company's sole reason for refusal to bargain was that the Board's certification of the Union is invalid, it follows that refusal to bargain was a violation of Section 8(a) (5) and (1) of the Act.

12
The Company also claims that the Board improperly invoked summary judgment procedures in finding an unfair labor practice and erred in refusing to allow the Company a hearing for the presentation of alleged newly-discovered evidence.  Review of the 'newly-discovered evidence' demonstrates that it constituted no more than an effort to reargue those matters raised in the Company's objection no. 5 above.  Furthermore, where the refusal to bargain is based on the alleged invalidity of the representation certificate, a single trial of the issue of representation is likewise dispositive of the charge of an unfair labor practice for refusal to bargain.  Pittsburgh Plate Glass Company v. N.L.R.B., 1941, 313 U.S. 146, 157-158, 61 S.Ct. 908, 85 L.Ed. 1251, 1261.  Summary judgment was appropriate.

13
The order of the National Labor Relations Board is

14
Enforced.

PER CURIAM:

16
The Petition for Rehearing is denied and no member of this panel nor Judge in regular active service on the Court having requested that the Court be polled on rehearing en banc, (Rule 35 Federal Rules of Appellate Procedure; Local Fifth Circuit Rule 12) the Petition for Rehearing En Banc is denied.

2. Buy More Services: This is where we can buy additional Packages, Services & Plans.

Now that we understand the "Store" tab, let's move on to the next step.

## Buying Resources

To buy resources from the control centre, we need to follow these steps:

1. Click on the "Buy Resources" option.
2. Type new values of QoS parameters into the New value fields.
3. Note that if the newly entered values exceed the included value (see in the Current Value fields), then we will have to pay for additional resources in accordance with the price per additional resource unit set by HSP (see in the Price per additional field).

Now that we know how to buy resources, let's move on to the next step.

## Understanding the Pricing Structure

The pricing structure for additional resources is set by the HSP (Hierarchical Service Provider). Here is an example of how the pricing works:

Let's say that we want to increase the bandwidth of our subscription from 10 Mbps to 20 Mbps. The current value of the bandwidth is 10 Mbps, and the included value is 5 Mbps. Since we want to increase the bandwidth by 10 Mbps (20 Mbps - 10 Mbps = 10 Mbps), we will have to pay for an additional 5 Mbps (10 Mbps - 5 Mbps = 5 Mbps). According to the pricing set by the HSP, each additional Mbps costs $5. Therefore, we will have to pay $25 for the additional 5 Mbps.

Now that we understand the pricing structure, let's move on to the conclusion.

## Conclusion

In this lesson, we learned how to buy resources from the control centre. We covered the following topics:

1. Logging into the Control Centre
2. Selecting the "Home" Tab
3. Understanding the "Store" Tab

The present invention relates to a method for the preparation of a lanthanum manganite powder which is useful as a material of various kinds of catalysts, electrodes and the like mainly in the form of a sintered body.
It is conventional that a powder of lanthanum manganite, which is sometimes partially substituted by strontium to have a composition formula of (La.sub.1-x Sr.sub.x).sub.y MnO.sub.z, in which x is 0 or a positive number not exceeding 0.5, y is a positive number in the range from 0.8 to 1 and z is a positive number not exceeding 3, is prepared by blending powders of each of a specified and weighed amount of lanthanum oxide, manganese carbonate and, optionally, strontium carbonate by a dry process, wet process or a combination of both and calcining the powder blend at a temperature of 1200.degree. C. or higher.
The above described conventional method for the preparation of a lanthanum manganite powder has problems in several respects. For example, it is almost unavoidable that a considerable portion of the starting powders remains unreacted in the product obtained by calcination and the amount of the unreacted starting materials can hardly be undetectably small even by conducting the process of calcination at a higher temperature for a longer length of time than usually undertaken. When a lanthanum manganite powder contains a substantial amount of unreacted lanthanum oxide, the sintered body prepared therefrom has a greatly decreased mechanical strength or the electric properties of the sintered body are very adversely affected. Disadvantages are also unavoidable by the high temperature calcination even when the lanthanum manganite powder is to be used in the form of a powder as such as in the applications for thermal spraying and the like because, even by setting aside the costs for the calcination at such a high temperature for a long time, growth of particles is unavoidable in the powder blend to give a semi-sintered mass of coarse particles which must be disintegrated and finely pulverized.
As a remedy for the above described disadvantages, Japanese Patent Kokai 4-74721 proposes a method for the preparation of a strontium-substituted lanthanum manganite powder in which an aqueous solution of water-soluble compounds of lanthanum, strontium and manganese in a specified proportion is admixed with an aqueous solution of ammonium carbonate to precipitate a composite carbonate and the precipitates are collected by filtration, dried and calcined to give a lanthanum manganite powder. A problem in the lanthanum manganite powder obtained by this method is that, although the amount of the unreacted starting materials in the thus produced powder can be small enough, the product powder is poor in respect of the flowability behavior so that the powder is not suitable for use, for example, in thermal spraying in which good flowability of the refractory powder is essential, for example, in order not to cause bridging of the powder in the feeder hopper.
