Overgrazing is the destruction of a grassland ecosystem; desertification is the destruction of a desert ecosystem.

Overgrazing results in barren exposed soil; if erosion continues, it contributes to desertification.

Overgrazing is brought about by livestock operations; desertification is brought about by crop cultivation.

Overgrazing and desertification are both a result of the introduction of non-native species coupled with extended droughts.

Question 13

Sustainable forestry:

seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture.

due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments.

approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions.

is all of the above.

Extra Solar Planets Lab

Extra Solar Planets Lab

  1. There are two types of planets in the solar system, terrestrial planets (like the Earth) and gas giants (like Jupiter). How do the mass, radius, and densities of these planetary types differ?
  2. Let’s say you discover a planet that’s 50 times the mass of the Earth.Even without visiting the planet, what might you presume about the planet (what will its general characteristics be)?
  3. How do the distances from the Sun differ for terrestrial and Jovian planets?
  4. Go to the Web site for the Extrasolar Planet http://exoplanet.eu/  Look through the page. How many planets have been discovered to date?

Click on the “Catalog” icon. Choose Candidates detected by Radial Velocity from the pull down Planet menu.  Look through many of the discoveries.  Are these planets similar in mass or are they all very different? (Note that masses are given in Jupiter Masses, thus a 1 value is equal to Jupiter’s mass.)

The masses of the planets detected by radial velocity seem to flucuatte greatly. They are not all similar.

Why do we mainly see only mass values?  (Think about the Radial Velocity detection method and what information it gives us about a planet.)

Choose Candidates detected by “Transiting Planets”.  Do these planets seem to be any different from the “radial velocity” planets?

Why do we see both mass and radius on many of these?  (Talk about the detection method.)

Click on the Diagrams button from the very top nav bar. You will see scatter plots or histograms of the properties of the candidates (for example, the numbers of objects in given ranges of mass).Select the Histogram Plot mode (near top right).  Select various properties to plot from the pull down menu and observe the results (e.g. orbital period, planet radius, planet mass, etc.). You don’t need to change any other settings.

Answer the following questions:

1.      Are most of the planets found using this method more massive or less massive than Jupiter?  Note again that the unit “MJ” means “Jupiter masses”.

2.      Do most of these planets have orbital periods that are shorter or longer than a year?

3.      Are most of the planets closer to or farther from their stars than the Earth is to the Sun?

4.      Now select the Scatter plot mode (top right).  Here you can look at the relationship between different planetary and stellar parameters for ALL planets that have been found.Inspect (see question below) the plot for PLOT 1: “Semi-Major Axis” versus “Planetary Mass,”;  using a linear scale for both axes (change the range of the x-axis to better see the data in certain areas of the plot, like min= 0, max = 10, and then max = 5, max = 2, and so on).

PLOT 2: “Semi-Major Axis” versus “Orbital Eccentricity,” choose x-axis min= 0, max = 10;

PLOT 3a: “Planetary Mass” versus “Planetary Radius” choose x-axis min= 0, max = 5, notice that our Jupiter would be found at (1,1) on the plot.  How are these planets different from our Jupiter?

PLOT 3b: keeping the variables the same, change the x-axis min= 0, max = 1, these are all the planets equal to or smaller than Jupiter.  How do these planets compare to the ones in our Solar System?

PLOT 3c: keeping the variables the same, change the x-axis min= 0, max = .1, these are all the planets similar to Earth-size, Earth would be at the point (.003,.09), very near the bottom left corner.  How do these planets compare to the terrestrial planets in our Solar System?

5.      Do you notice any patterns or clumps? What does this tell us about the planets we’ve found?  Describe patterns for each plot listed above, be sure to label your answer to each plot.

6.      Research what the “Habitable Zone” is for a star and define it in your own words(provide your reference).

 

a.       Where is the Habitable Zone in our own Solary System?

 

b.      What kind of life would we expect to be in this “Habitable Zone” around other stars?

 

 

c.       What would it take for life to survive outside of a planet’s Habitable Zone? Explain. (What physical processes might be going on?)

 

d.      Are there places in our own Solar System outside the Habitable Zone where we theorize life might exist?  Explain, try to be specific in your locations.

Write a summary that includes a short comparison between the properties of the planets in our Solar System that you studied above to the properties of the extrasolar planets you studied here.  What conclusions can you draw about Earth-sized planets, are they rare or numerous?

 

Make sure to include all references.

Unit Lesson Industrial hygienists require at least a basic knowledge and understanding of a number of scientific disciplines. Toxicology is one of the more important disciplines for the industrial hygienist. A primary mission of industrial hygiene is to prevent injuries and illnesses by reducing the risks associated with hazards. Toxicology data are valuable tools for accomplishing that mission. Many students have never really given the field of toxicology that much thought, or if you took a class in your studies, you may have come to the conclusion that toxicology is either too difficult or boring. However, if shown the following picture, most would automatically say “Poison,” so there is at least some recognition of toxicology.

UNIT II STUDY GUIDE

How an Understanding of Toxicology Helps in the Industrial Hygiene Practice

 

 

 

MOS 6301, Advanced Industrial Hygiene 2

UNIT x STUDY GUIDE

Title

As your textbook has pointed out, the most common definition of toxicology is the study of poisons (Fuller, 2015). This should automatically bring up several questions for the aspiring industrial hygienist. How can toxicological data be used to help you with your job? Where can you find the data that can help you? How can you translate this stuff into something you can understand? This lesson will not make you an expert on toxicology. You will have to take the advanced toxicology class for your master’s degree, and that class will go in depth much more than this one unit. However, this lesson is designed to help you understand where you can obtain data to assist you with industrial hygiene work and some basic understanding of what the data mean. A basic saying in toxicology is “the dose makes the poison.” Loosely, this means that at a low enough exposure, chemicals will not cause harm, but as the exposure increases, the risk of harm also increases. You can reach an exposure level where harm actually occurs. In controlling risk, it would be nice if we could identify that point and make sure no workers were ever exposed to a chemical at that level. One objective of toxicology studies is to identify the dose below which harm does not occur. A common way that data is displayed is the dose-response curve. An example of a dose-response curve can be seen on page 79 of the textbook (Fuller, 2015). Dose-Response The textbook calls the point at which some response occurs (for Figure 4-2 the response is percent of liver hypertrophy) the threshold dose (Fuller, 2015). Some more commonly used terms in toxicology are lowest observed adverse effect level (LOAEL) and no observed adverse effect level (NOAEL). The LOAEL represents the lowest exposure at which some response was recorded (typically from animal studies). The NOAEL represents the highest dose at which no response was seen. This appears to make it fairly simple to just say, let’s keep the workers’ exposures less than the NOAEL and then no one will get sick! However, it is not quite that simple. First, most NOAELs are generated based on animal studies. Results from animal studies do not translate directly to humans for various reasons including differences in body sizes (weight) and differences in body functions (hormones, etc.). Second, there can be wide variations in how individual workers react to an exposure to a chemical. Differences in gender, weight, age, and even a person’s genetic sequences can alter the concentration at which they would react and the level of the reaction (Wheeler, Park, Bailer, & Whitaker, 2015). For this reason, organizations that establish occupational exposure limits (OELs) typically apply a safety factor. The level of the safety factor will depend on how serious the health effect may be.

Toxicology is the study of poisons. (Brutlag, n.d.)

 

 

 

MOS 6301, Advanced Industrial Hygiene 3

UNIT x STUDY GUIDE

Title

The dose-response curve can inform us of the level of toxicity compared to other compounds and the size of the safety factor that must be applied. When you look at dose-response curves, you will see many different slopes to the curves. Some are quite steep, while others are rather shallow. If you think about this, it should indicate to you that the compounds with a relatively steep slope only take a small increase in dose to greatly increase the response, while compounds with a shallow curve require a much greater increase in dose to cause a significant increase in the response. Other terms that can be important for an industrial hygienist trying to assess the risk to a health hazard include the LD50 and LC50. These terms represent the dose at which 50 percent of an exposed population die. LD50 is used when the exposure occurs by ingestion or dermal exposure. LC50 is used when the exposure is by inhalation. Both of the terms represent acute exposures, meaning they are short-term exposures with acute effects. In other words, they are not used for chronic exposures resulting in chronic diseases like cancer. Other results that are not reported as often in safety data sheets (SDS) are TCLo, TC50, TDLo, and TD50. These terms are quite similar to the LD50 and LC50 except they identify the dose or concentration where 50 percent of the subjects show some toxic response or the lowest dose or concentration where any subject shows the toxic response. Target Organs Another piece of information that can be important to the industrial hygienist is the target organ. Many compounds will exert a toxic effect to one or more specific organs of the body. Knowing which organ a compound could affect can help in determining the best protective measures to use. For example, if a compound is known to primarily be a lung toxin, reducing personal exposures by inhalation would be somewhat important. Some compounds are immunotoxins. These compounds can cause unique problems for the industrial hygienist. Some compounds, after repeated exposures, can cause a sensitization reaction (allergic response) in a small percentage of exposed workers. These workers will exhibit future responses to much lower concentrations of the chemical. The response can be either a respiratory reaction or a dermal reaction. Some of the common chemicals used in industrial settings that can be immunotoxins are formaldehyde, some of the isocyanates, some metal fumes, and bisphenol A (BPA). Some plants have had to move workers to other areas of a facility because of these reactions. Chronic Health Effects Another important consideration is whether a compound can cause chronic health effects. Most workers are highly concerned about a compound’s ability to produce cancer. Compounds that can cause cancer are called carcinogens. Some cancers start as changes in the DNA called mutations. Chemicals that can cause these mutations are called mutagens. Not all mutations result in cancer. All humans suffer some mutations during their lifetime. For the most part, the mutations are benign and are eliminated as the body turns over cells in a process called apoptosis. However, sometimes the mutations result in an uncontrolled growth of cells resulting in cancer. Also, not all cancers start with a mutation. Asbestos is a good example of a carcinogen that is not a mutagen. There are several organizations that rate the carcinogenicity of compounds the industrial hygienist may see. The two that most industrial hygienists refer to the most are the Occupational Safety and Health Administration (OSHA) and the American Conference of Governmental Industrial Hygienists (ACGIH). You can generally find the carcinogenic ratings of compounds in Section 11 of the SDS. Finally, the industrial hygienist should also consider a chemical’s ability to affect reproductivity (reproductive toxins) or the development of a fetus (teratogens). In some settings, this can be rather important to protect workers. For example, most of the anti-neoplastic drugs used in chemotherapy are also reproductive toxins and teratogens. There are numerous published studies showing spontaneous abortions in females working in oncology clinics due to exposures to these drugs. An industrial hygienist working in an oncology clinic would need to set up a rigorous program to reduce the risk associated with handling these drugs.

PART II: CASE STUDY

Directions: Review “The Case of Chung Ming” on page 44 of the text. Develop a treatment plan for Chung Ming. Your final document should be at least 2-3 pages and adhere to APA standards, including in text citations. Please visit the Academic Resource Center for concise APA guidelines.
Chung Ming is a teenager,14 years old,and he
is ethnic Chinese. His parents immigrated
from China when Ming was roughly 9 years
old. Ming’s parents have not yet mastered the
English language and in some cases, he has
had to translate for his family. Lately, Ming
has been skipping school and he has been
hanging out with a group of other Asian
(mostly Chinese) youth that have established
a small gang.
Ming’s parents are humiliated by his
behavior and do not act as if they are really ready
to conduct counseling. They express that they
are very troubled by Ming’s behavior and even
that he brings dishonor on his family. Ming, on
the other hand, is much more Westernized than
his parents and he notes that many of his friends
have forsaken much of their Chinese views
for those more consistent with mainstream
American society.
Ming seems indifferent as you watch him
while his parents talk, noting that Ming stays
out late,drinks at age 14,and he has even stolen small items from various stores in the neigh-
borhood.You can tell by observing that Ming’s
father has difficulty with English and is a bit
withdrawn. The mother is also withdrawn and
does not offer anything to the conversation
throughout most of the session.
Ming is on juvenile probation and he
seems to meet the requirements of his supervi-
sion. The mere fact that he is on probation is
problematic with his parents and is also a
source of shame for all members of the family.
After the session, you are fairly sure that
Ming is still engaged in illegal activities with his
prior gang. You make it a point to ultimately
contact his probation/parole officer during the
next week.
Given the dynamics of this traditionally
Chinese family, Ming’s advanced acculturation
in Western culture, and the lack of concern
that Ming has, you realize that there are many
more factors at play than Ming’s simple misbe-
havior.You consider the cultural dynamics and
begin to develop a plan

Why is Manhattan Beach one of most expensive neighborhood in Brooklyn? It is not close to the city or public transportation. Yes, it is by the water just like many other areas in New York. But what have made it this way? By looking at the maps there are weren’t much going on. Only few things and Temple. Such as US public hospital and Air force reservation. How come those became unnecessary and million dollar land came along. Did all the workers and fisherman leave and left the land behind which became available for Russian and Jewish emigrants? If so why land on Brighton broader doesn’t coast as much as it is on Manhattan beach.

Another look to a Emmons Avenue Creek which was originally built for easier access and quite space for fishing. Back then there were no housing from Sheepshead Bay or Manhattan beach side. When did this all became irrelevant and deconstruct itself into Holocaust memorial with annual events and gathering. Fresh seafood now turns into too many sushi bars within one block and boat parties during a summer while Manhattan beach resents barely use public transportation. Why would you want to live here if you can afford a penthouse on the island? Dangerous flooding zone have been proved by recent Sandy and yet this neighborhood is the hottest spot for real estate agents.

Focus The Creek between Sheepshead Bay and Manhattan beach. Including Holocaust Memorial Park. The purpose to focus on use of creek that starts of Manhattan Beach.The canal itself haven’t change thought the years but population of the neighborhood definitely have. The Kingsborough Community College is built on part on the land that been extended with extra rocks which means whoever had idea of this school wasn’t deepened on taking the space of Manhattan Beach. They were extending it and building at the same time.

1. So here is my helpers and inspirations for this topic. At first I have looked at Historic aerials website and have seen how the area changed thought seventy years. This were I have learned about attached stones as platform for Kingsborogh college and US air force factory.

2,3. I found a great use of different pictures that I’m planning to attached my final version of paper from Brooklyn Historical Society and Brooklyn Public Library.

4,5. Local newspapers like sheepsheadbaybites.com and brooklyndaily.com have a little bit of information.

6. GILLMAN, LUCY P.. “CONEY ISLAND”. New York History 36.3 (1955): 255–290. This article doesn’t only cover history of Coney island and its developments but mentions the demography of immigrant population. But before that the hotels were most of buildings on the Manhattan beach area! Hotels are now apartment buildings!

7. Wildsam Field Guide Brooklyn. Wildsam Field Guides, 2015. Print. It have been purchased for the love of Brooklyn and became useful. It’s a collection of essays and Brooklyn guides by different authors. So like how Sheepshead bay fishing was shut down because of pollution. And mentions one of oldest Sheepshead Bay families that still operates since 1918.

8. The Weekly Nabe http://theweeklynabe.com/2012/08/27/sheepshead-bay-brooklyn-history/

Its interesting and just inspiring source how to organize the final version of my paper.

Ideally I will also find those two and review them as well . Merlis, Brian, Lee A. Rosenzweig, and I. Stephen. Miller. Brooklyn’s Gold Coast: The Sheepshead Bay Communities. Brooklyn: Sheepshead Bay Historical Society, 1997. Print.and Lines, Ruth L. The Story of Sheepshead Bay, Manhattan Beach and the Sheepshead Bay Library. Brooklyn, NY: Publisher Not Identified, 1949. Print.
