Overview of the Branches of Chemistry

Overview of the Branches of Chemistry There are several branches of chemistry. Here is a list of the main branches of chemistry, with an overview of what each branch of chemistry studies. Types of Chemistry Agrochemistry - This branch of chemistry may also be called agricultural chemistry. It deals with the application of chemistry for agricultural production, food processing, and environmental remediation as a result of agriculture. Analytical Chemistry - Analytical chemistry is the branch of chemistry involved with studying the properties of materials or developing tools to analyze materials. Astrochemistry - Astrochemistry is the study of the composition and reactions of the chemical elements and molecules found in the stars and in space and of the interactions between this matter and radiation. Biochemistry - Biochemistry is the branch of chemistry concerned with the chemical reactions that occur inside living organisms. Chemical Engineering - Chemical engineering involves the practical application of chemistry to solve problems. Chemistry History - Chemistry history is the branch of chemistry and history that traces the evolution over time of chemistry as a science. To some extent, alchemy is included as a topic of chemistry history. Cluster Chemistry - This branch of chemistry involves the study of clusters of bound atoms, intermediate in size between single molecules and bulk solids. Combinatorial Chemistry - Combinatorial chemistry involves computer simulation of molecules and reactions between molecules. Electrochemistry - Electrochemistry is the branch of chemistry that involves the study of chemical reactions in a solution at the interface between an ionic conductor and an electrical conductor. Electrochemistry may be considered to be the study of electron transfer, particularly within an electrolytic solution. Environmental Chemistry - Environmental chemistry is the chemistry associated with soil, air, and water and of human impact on natural systems. Food Chemistry - Food chemistry is the branch of chemistry associated with the chemical processes of all aspects of food. Many aspects of food chemistry rely on biochemistry, but it incorporates other disciplines as well. General Chemistry - General chemistry examines the structure of matter and the reaction between matter and energy. It is the basis for the other branches of chemistry. Geochemistry - Geochemistry is the study of chemical composition and chemical processes associated with the Earth and other planets. Green Chemistry - Green chemistry is concerned with processes and products that eliminate or reduce the use or release of hazardous substances. Remediation may be considered part of green chemistry. Inorganic Chemistry - Inorganic chemistry is the branch of chemistry that deals with the structure and interactions between inorganic compounds, which are any compounds that arent based in carbon-hydrogen bonds. Kinetics - Kinetics examines the rate at which chemical reactions occur and the factors that affect the rate of chemical processes. Medicinal Chemistry - Medicinal chemistry is chemistry as it applies to pharmacology and medicine. Nanochemistry - Nanochemistry is concerned with the assembly and properties of nanoscale assemblies of atoms or molecules. Nuclear Chemistry - Nuclear chemistry is the branch of chemistry associated with nuclear reactions and isotopes. Organic Chemistry - This branch of chemistry deals with the chemistry of carbon and living things. Photochemistry - Photochemistry is the branch of chemistry concerned with interactions between light and matter. Physical Chemistry - Physical chemistry is the branch of chemistry that applies physics to the study of chemistry. Quantum mechanics and thermodynamics are examples of physical chemistry disciplines. Polymer Chemistry - Polymer chemistry or macromolecular chemistry is the branch of chemistry the examines the structure and properties of macromolecules and polymers and finds new ways to synthesize these molecules. Solid State Chemistry - Solid state chemistry is the branch of chemistry that is focused on the structure, properties, and chemical processes that occur in the solid phase. Much of solid state chemistry deals with the synthesis and characterization of new solid state materials. Spectroscopy - Spectroscopy examines the interactions between matter and electromagnetic radiation as a function of wavelength. Spectroscopy commonly is used to detect and identify chemicals based on their spectroscopic signatures. Thermochemistry - Thermochemistry may be considered a type of Physical Chemistry. Thermochemistry involves the study of thermal effects of chemical reactions and the thermal energy exchange between processes. Theoretical Chemistry - Theoretical chemistry applies chemistry and physics calculations to explain or make predictions about chemical phenomena. There is overlap between the different branches of chemistry. For example, a polymer chemist typically knows a lot of organic chemistry. A scientist specializing in thermochemistry knows a lot of physical chemistry.

A Thanksgiving Guide for College Students

A Thanksgiving Guide for College Students Thanksgiving break, for many college students, is an oasis in the middle of fall semester. Its a chance to return home and recharge. You can take a break from midterms and papers. For a lot of students, it might be their first chance to get some good food and spend time with old friends. Lots of students go home for Thanksgiving, but some stay on campus. Others head to a friend or roommates house to celebrate the holiday. No matter your situation, though, there are things you can do to make sure you squeeze every last drop out of the long weekend. Friends, Family, and Relationships Thanksgiving is nearly always about friends and family. And while every college student has a unique situation when it comes to their nearest and dearest, nearly everyone needs a little love around the holidays. Some families are less supportive than others. If you find being back home stressful, try planning to see friends or a trip to your favorite coffee shop. For many students, its the first chance they have to visit with friends from high school. If you had a large circle of friends, getting to see everyone you wanted to see might be hard. After all, the Thanksgiving break is only a few days, and most people will have some family obligations as well. Because of this, it is wise to try to plan group activities where you can spend time with as many of your old friends as possible. Dealing With Change If Thanksgiving is the first time youve been home since the start of college, you may have a hard time adjusting to being back. After months of the freedom to come and go as you please, having a curfew again might be hard to swallow. Things around your town have probably changed, too. You may have new interests and hobbies that you didnt have before, which your family may or may not approve of. Dealing with change isnt easy for anyone, including your parents. Try to approach the differences with an open mind. College is about moving from childhood to your adult life and its a process which is why you still have to follow your parents rules- but it wont be like that forever. Be patient when your parents start treating you like youre back in high school; they need time to adjust to their child growing up. When you start getting frustrated remind yourself its just a long weekend, youll be back at school before you know it. Dealing With Politics Its not uncommon for students to return home with new ideas or insight into the politics of the world. If your politics no longer align with your families, it could lead to some unpleasant conversations. Many people attempt to avoid discussing politics during the holiday but if thats not an option, view it as a learning experience. Ask your family members to explain their political beliefs to you. Even if you dont agree, allowing others to feel like theyve been heard can ease tensions. Its also easier to explain your beliefs when you have shown that you respect the other person enough to hear what they have to say. Heading Home Thanksgiving is one of the busiest travel times of the year, so knowing what to expect can prevent a fun trip home from turning into a travel nightmare. Knowing what to pack when heading home for Thanksgiving is half the battle. The other half is planning your route home. If youre in charge of purchasing your airline ticket, youll want to book it at least six weeks in advance. The Wednesday before Thanksgiving is one of the biggest travel days of the year, so youll want to avoid it if you can. If you have a class scheduled that day, talk to your professor about ways to accommodate your absence so you can leave earlier in the week. Dont worry if you forgot to buy your ticket home; there are ways to find last-minute student travel deals. If you do have to leave on Wednesday, leave early and be prepared to deal with travel delays and crowds. Staying on Top of Your Academics For most students, Thanksgiving falls either right before or right after midterms. So just because youre relaxing and hanging out with people over the break doesnt mean you can let your academics slide. While staying on top of your coursework is challenging, it isnt impossible. Thanksgiving is your first real chance to get to learn how to manage homework over a college break. Even if your professors didnt assign you anything over the break, you probably have a larger project or paper that you can work on. Remember, the end of the semester is really only a few weeks away. The time will pass faster than you think and saying you have to study is a great excuse to get out of an awkward conversation with extended family members.

Unemployment Benefits and Financial Difficulty Essay

Unemployment Benefits and Financial Difficulty - Essay Example Unemployment is not something that can be easily explained, especially considering that people who find themselves unemployed do not fall into one distinct group. There are a number of causes and reasons why one person finds himself unemployed with structural unemployment, frictional unemployment and seasonal unemployment being the most common types. Francine, on the other hand, is affected by seasonal unemployment which refers to individuals who hold jobs for a distinct period of time such as the job she had at the ski resort and which ended because the winter season is over. Her type of unemployment is hard to define since she is only available for a period of time for a specific kind of work (Tucker 172). However, she does not qualify for unemployment benefits since it is clear that she is not undergoing any type of financial difficulty being as she has stated she is not interested in working until the next winter season. Beauvoir, on the other hand, is affected by structural unem ployment where the skill set that she has no longer matches with the requirements of her place of work. This is a major problem that is occurring in the present time as the world becomes more technologically oriented. Another problem with this type of unemployment is the fact that it can last for a long period of time simply because firms are not willing to retrain their workers as a result of cost or the time involved (Tucker 172). Because Beauvoir was a full-time employee and did have the skills that were needed to carry out her job up to the time that the firm became upgraded, she does deserve the unemployment benefits to keep her going as she looks for a way to enhance on her computer skills.

Broken Rules

The first discussion in this essay will focus on the reasons why institutional policies are broken; should those policies ever be broken; and discuss possible solutions that could eliminate the need to break these rules, which would lessen the pressure employees felt when the policies of the organization were not followed. The second discussion will be about the violent behavior in school-aged children and explore possible solutions to dealing with the explosive rage exhibited toward childcare workers. A problem with breaking rules during the flu and cold season puts not only other children’s health at risk, but the staff’s also.The cleaning schedule for childcare facilities should be on a daily schedule. Many organizations keep a spray bottle of bleach and water to wipe down tables, chairs, desks, and play areas. Others dip all of the toys in a bucket of bleach water at the end of the day to sterilize them, but this does not clean toys that are handled and played with amongst the children before the end of the shift. Facilities hold policies that if the children are running a fever, coughing, sneezing, and have runny noses, the parents should keep the child home or find alternative care while the child recuperates.Many of the organizations realize that in today’s world extended families could be located thousands of miles apart; and finding trustworthy alternative childcare is difficult. Thus, many facilities break their own policies in taking the sick children into their care to help the families, knowing that parents must go to work. The facilities also realize a financial loss in their economic budget when parents hire alternative childcare during the times that the children are ill. And ideal situation in childcare would be to recognize and implement childcare through all the ups and downs that families experience.I propose that childcare facilities create an area away from the main rooms of bustling activities for the ill child or chi ldren. The separate wing would be a quieter place with subdued lighting to induce restful activities while the child recuperates from their compromised physical conditions. The instructor/teacher/worker, who is assigned to that area for the shift, can initiate quiet activities and instruction time. This separate area allows for more nap times in a less busy environment; extra hydration can be given to the ill child without hindrance from the other children.Having assigned personnel to take care of the sick children and keeping them isolated from the main population of the facility, would do more in restricting the spread of the flu and cold viruses to the rest of the children and staff. Parents would not have to struggle with finding alternative childcare, and the facilities would be able to maintain a stable income by taking care of ill children. Most childcare facilities are considered small businesses; therefore, they would be eligible for certain grants to merge these two types of care packages for the parents’ choice of options.Or the facility could charge an extra fee for that month to the child’s family to offset the extra expense in tending to an ill child. The second position of this essay deals with the problems of explosive rage in children towards classmates and staff. Alarming rates in acts of violence have increased dramatically in lower elementary grades. â€Å"Elementary school principals and safety experts say they're seeing more violence and aggression than ever among their youngest students, pointing to what they see as an alarming rise in assaults and threats to classmates and teachers.† 1 Working with the parents to control the unacceptable behavior of their children has failed, so facilities have approached the problem with stricter discipline to get the attention of the children and the parents. It is rare to see full time counselors or social workers in the elementary grades. Many schools districts have opted to sha re these positions to ease the budget demands. Police have to be called in to subdue parents upset with the disciplining of their child.For instance, Minnesota has had to suspend nearly 4,000 kindergartners for violent behavior in 2004 to 2006. This is counterproductive to the classroom environment and hinders students from learning. To gain control of the classroom or childcare area, I propose that priorities be re-evaluated to obtain a higher budget level for implementing full time counselors and security positions. Ongoing certification classes for educators and childcare workers should place emphasis on what constitutes effective treatment for violent children.It is not just a gift to be able to work with difficult children, it takes the philosophy of the teacher/worker that they can make a difference, for the good, in the children’s attitudes. I believe that full time social workers or counselors in the childcare institutions can keep track of the nutrition, health, and sleep patterns of the child that exhibits aggressive behavior. Unions of childcare workers can unite to press Congress for more active research, comparing pre-natal care as it relates to aggression in children. Communities can work along with the schools or other children’s facilities with after school programs.Many ideas can be implemented for the prevention of juvenile delinquency; it only takes someone or some group to initiate and facilitate them.

Importance of Obeying Traffic Laws Essay - 1555 Words

The Importance of Obeying Traffic Laws Traffic laws are designed to protect you and other drivers on the road. If we do not follow them we are not only putting ourselves at risk but also innocent bystanders and drivers. By knowing the rules of the road, practicing good driving skills and generally taking care as a road user, you help play a vital role in preventing a crash. You will also be making road safety policies more effective. Many factors play a role in road safety including following the speed limits that are posted and making sure safety equipment is properly installed and used. I will also discuss the skills that are expected and needed to be an efficient driver including the ability to act responsibly, the ability to†¦show more content†¦Basically the higher the speed of a vehicle, the more difficult collision avoidance becomes and the greater the damage if a collision does occur. Speeding is defined as the act or an instance of driving, especially a motor vehicle, faster than is allowed by law. Speeding is often one component of aggressive driving which is defined as committing a combination of moving traffic offenses so as to endanger other persons or property. There are strong direct relationships between the speed at which we drive and the risk of crash involvement and the injuries sustained if a crash results. The probability of injury and the severity of those injuries increases exponentially with vehicle speed. Even small increases in speeds result in a large increase in the forces experienced by the vehicle occupants or other road users. Put simply, the faster you drive, the harder you hit and the more severe the injuries you or someone else are likely to suffer. Traveling over the speed limit can be especially dangerous in bad weather conditions.
