Air Pollution Control Devices for Stationary Sources: Stationary sources of air pollution emissions, such as power plants, steel mills, smelters, cement plants, refineries, and other industrial processes, release contaminants into the atmosphere as particulates, aerosols, vapors, or gases. These emissions are typically controlled to high efficiencies using a wide range of air pollution control devices. The selection of the appropriate control technology is determined by the pollutant collected, the stationary source conditions, and the control efficiency required. In some cases, pollutant emissions can be reduced significantly through process modifications and combustion controls. Questions (Five points each) Based on the different Philippine Regulations such as the Philippine Clean Air Act of 1999 (RA 8749) and the DENR Administrative Order (DAO) 2007-22, Identify what type of pollution control devices that are applicable for the following major industries and why? Name at least TWO and EXPLAIN YOUR SELECTION Criteria. 1. Fossil-fueled Plant over 10Meg awatt Capacity 2. Petroleum refinery/Petrochemical Plant 3. Steel plant/Ferro alloy Smelters 4. Cement Manufacturing Plant
1. Fossil-fueled Plant over 10 Megawatt Capacity: Electrostatic precipitators (ESPs) and flue gas desulfurization (FGD) systems. ESPs remove particulate matter (PM), and FGD systems control sulfur dioxide \(So_{2}\) emissions.
2. Petroleum refinery/Petrochemical Plant: Catalytic converters and thermal oxidizers. Catalytic converters reduce volatile organic compound (VOC) emissions, while thermal oxidizers control hazardous air pollutants (HAPs) and VOCs.
3. Steel plant/Ferro alloy Smelters: Baghouses and scrubbers. Baghouses capture particulate matter (PM), and scrubbers control sulfur dioxide (\(So_{2}\)) and acidic gas emissions.
4. Cement Manufacturing Plant: Fabric filters (baghouses) and selective non-catalytic reduction (SNCR) systems. Fabric filters control particulate matter (PM) emissions, and SNCR systems reduce nitrogen oxide (NOx) emissions.
Fossil-fueled Plant over 10 Megawatt Capacity:
a. Flue Gas Desulfurization (FGD) System: FGD systems are applicable to fossil-fueled plants over 10 Megawatt capacity to control sulfur dioxide (\(So_{2}\)) emissions. These systems use various methods like wet scrubbing or dry sorbent injection to remove \(So_{2}\) from flue gas. The selection criterion for FGD systems depends on factors such as the sulfur content of the fuel, flue gas temperature, and desired \(So_{2}\) removal efficiency. FGD systems are effective in reducing \(So_{2}\) emissions, ensuring compliance with air quality regulations and minimizing the environmental impact of fossil-fueled plants.
b. Electrostatic Precipitators (ESPs): ESPs are commonly used in large fossil-fueled plants to control particulate matter (PM) emissions. These devices utilize an electrostatic charge to attract and capture PM from the flue gas. ESPs can achieve high collection efficiencies and are suitable for handling large volumes of gas. The selection criteria for ESPs consider factors such as gas velocity, particulate size distribution, and electrical characteristics. ESPs help in maintaining air quality standards by removing harmful particles from the emissions.Petroleum Refinery/Petrochemical Plant:
a. Catalytic Converters: Catalytic converters are effective pollution control devices for reducing volatile organic compound (VOC) emissions in petroleum refineries and petrochemical plants. These converters utilize catalysts to promote chemical reactions that convert VOCs into less harmful substances. The selection of catalytic converters depends on factors such as the types of VOCs present, operating conditions, and desired conversion efficiency. Catalytic converters play a crucial role in minimizing VOC emissions and improving air quality in these industries.b. Thermal Oxidizers: Thermal oxidizers are another suitable option for controlling emissions in petroleum refineries and petrochemical plants. These devices use high temperatures to oxidize and break down VOCs and hazardous air pollutants (HAPs) into carbon dioxide (\(Co_{2}\)) and water vapor. The selection criteria for thermal oxidizers consider factors like the types and concentrations of pollutants, temperature requirements, and residence time. Thermal oxidizers provide efficient destruction of VOCs and HAPs, ensuring compliance with emission standards and protecting the environment.For more such question on Fossil-fueled

How do the common phrases, “high brow”, “low brow” and “well-rounded” have roots in Phrenology?
The common phrases "high brow," "low brow," and "well-rounded" have roots in Phrenology, which is a pseudoscience that involves the study of the shape and size of the skull in order to determine a person's character, intelligence, and other traits.
What are the phrases about?Phrenologists believed that the brain was divided into different regions, each responsible for specific mental faculties, and that the size and shape of the skull reflected the size and development of these regions. They believed that certain regions of the skull were associated with intelligence, morality, and other positive traits, while others were associated with negative traits such as aggression or criminal behavior.
Based on this belief, Phrenologists categorized people into different groups based on the shape and size of their skulls.
Therefore, These terms were later used in a metaphorical sense to describe people's general characteristics and intellectual pursuits, rather than their physical characteristics.

Which of the following is NOT true about oxidative enzyme response to aerobic training?
a) phosphorylase and phosphofructokinase activities are particularly high
b) it can also be stimulated by high-intensity interval training
c) activity increases even after VO2 max has plateaued
d) it exerts a glycogen-sparing effect in muscle
Which states that phosphorylase and phosphofructokinase activities are particularly high in response to aerobic training. This statement is not true as these enzymes are primarily involved in anaerobic glycolysis, which is not the primary energy pathway during aerobic exercise.
The correct answer to the question is option A
On the other hand, options B, C, and D are all true statements about oxidative enzyme response to aerobic training. High-intensity interval training (HIIT) has been shown to increase oxidative enzyme activity in muscle cells, leading to improved endurance performance. Additionally, oxidative enzyme activity continues to increase even after VO2 max has plateaued, indicating that other adaptations are occurring to support aerobic metabolism.
Finally, oxidative enzyme activity exerts a glycogen-sparing effect in muscle, which means that the body is better able to use fat as a fuel source during exercise, preserving glycogen stores for later use. This is a key adaptation that occurs with aerobic training and can improve endurance performance.

The US government pays for all of its citizens’ medical care.
A.
True
B.
False
The statement "the US government does not pay for all of its citizens' medical care" is false.
In the United States, healthcare is primarily funded through a combination of private health insurance, employer-sponsored plans, and government programs such as Medicare and Medicaid.
Medicare is a federal program that provides health insurance for individuals aged 65 and older, as well as certain younger individuals with disabilities. It is funded through payroll taxes and premiums paid by beneficiaries.
Medicaid, on the other hand, is a joint federal and state program that provides health coverage to low-income individuals and families. It is funded by both the federal government and individual states.
While the government does play a role in providing healthcare coverage through these programs, it does not cover all citizens or all medical expenses. Many individuals in the US obtain health insurance through their employers, while others purchase private health insurance plans on their own.
It's important to note that the US healthcare system is complex and involves a mix of public and private funding. Access to healthcare and coverage varies among individuals based on their insurance status, income, and other factors.

How quickly a drug enters your bloodstream also depends on_______
A. The amount of food eaten
B. The active ingredients in the drug
C. The time of day the drug was taken
D. Inhaling
Answer: The amount of food eaten.
Explanation: Drug absorption is the process by which a drug enters the bloodstream after administration. The rate and extent of drug absorption depend on various factors, such as the physicochemical properties of the drug, the formulation, and the route of administration.
One of the factors that can affect drug absorption is the amount of food eaten before or after taking a drug. Food can influence drug absorption by altering gastric emptying, gastrointestinal motility, pH, bile secretion, and blood flow. Food can also interact with drugs directly or indirectly by affecting their solubility, stability, or metabolism.
The effect of food on drug absorption can be either positive or negative, depending on the drug and the type of food. For example, some drugs are better absorbed when taken with a high-fat meal, such as griseofulvin, saquinavir, and cyclosporine. Other drugs are better absorbed when taken on an empty stomach, such as penicillin, tetracycline, and levodopa. Some drugs have variable absorption depending on the type of food, such as warfarin, which can be affected by vitamin K-rich foods.
Therefore, the amount of food eaten can affect how quickly a drug enters the bloodstream and how much of it reaches the systemic circulation. This can have implications for the efficacy and safety of drug therapy. It is important to follow the instructions on how to take a drug with respect to food intake to optimize its absorption and avoid adverse effects.
