What Does Starvation Do To The Body?

We all know what hunger feels like, but what happens to our bodies if we stop eating? What exactly is the science behind starvation?

How Long Can a Person Survive Without Food?
http://www.scientificamerican.com/article/how-long-can-a-person-sur/
“The duration of survival without food is greatly influenced by factors such as body weight, genetic variation, other health considerations and, most importantly, the presence or absence of dehydration. For total starvation in healthy individuals receiving adequate hydration, reliable data on survival are hard to obtain.”

The Psychology of Hunger
http://www.apa.org/monitor/2013/10/hunger.aspx
“In November 1944, 36 young men took up residence in the corridors and rooms of the University of Minnesota football stadium. They were not members of the football team. Rather, they were volunteers preparing for a nearly yearlong experiment on the psychological and physiological effects of starvation. Known as the Minnesota Starvation Experiment, the study was a project of the newly established Laboratory of Physiological Hygiene at the University of Minnesota, an interdisciplinary research institution with an emphasis on nutrition and human biology.”

Brain Foods: The Effects of Nutrients on Brain Function
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2805706/
“It has long been suspected that the relative abundance of specific nutrients can affect cognitive processes and emotions. Newly described influences of dietary factors on neuronal function and synaptic plasticity have revealed some of the vital mechanisms that are responsible for the action of diet on brain health and mental function. Several gut hormones that can enter the brain, or that are produced in the brain itself, influence cognitive ability.”

Chemistry Dissertation Help: Chemistry is subject which needs a sound attention to complete any kind of work like dissertation. A mere class is not sufficient to teach or guide the students how to make a perfect dissertation. Because there is only one teacher for many students so only few students can able to catch the topic. What about the rest of the students? Those pupils who are unable to understand a topic in the class? Here is the solution, Chemistry Dissertation Help.  Chemistry Dissertation Help provides chemistry based Dissertation for school level to college level. If the students posses a personal computer, internet connection, headphone or microphone they can access this online tutorial service.

What Is Dissertation? Dissertation is the cluster of documents on which students have made their research on a particular subject. This is a scientific method based and formal write ups and lots of references and also a particular format of writing. So it needs special attention and care at the time of making. But often it seems that students cannot meet the desired standard or writing because of lacking proper research on the topic and lacking of proper guidance of teachers. But if the students start relies on the chemistry dissertation help, they never will be disappointed with the standard of their dissertation.

What Is Chemistry Dissertation? There are some differences between chemistry dissertation and any other dissertation. The dissertation of any arts based subject needs only paper work and research and normal write ups. But chemistry dissertation needs a completely research based write ups, practical class with chemical elements, scientific method based format and also write ups on experiment of various chemicals. So it becomes an impossible matter to the students to make that complete. Their parents are also busy in their own work so they sent their children to the private coaching centers but the scenario is the same there are also only teacher for many students.

Online Tutors of Chemistry Dissertation Help: Chemistry Dissertation Help can read the mind of the students so they recruit the best academically expertise for making dissertation. The tutors are always busy in researching that how to present new kind of chemistry based dissertations for the students. Sometimes they communicate with the students through video conference regarding the chemistry based dissertation. Students can contact with the tutors any time whenever they felt any kind of problem to understanding the dissertation.

Conclusion:Chemistry Dissertation is one such service provider that can easily meet your expectations levels as compared to other service providers. This is the reason why they make it a point to thoroughly check for level of knowledge and education in Chemistry that prospective tutors possess and also their levels of communication and psychological skills that will aid in providing better tutorial services. The aim is to always submit and meet targeted deadlines to avoid any inconvenience to students. Pricing too is structured bearing in mind concerns that students, parents and guardians share regarding value for money for services rendered.

If you own a laptop computer, chances are very very good that it is probably powered by a lithium-ion (Li-ion) battery. This battery type has found application in a wide variety of consumer electronics, including PDAs and cell phones. They have gained widespread popularity due to economic and technical reasons, particularly their high charge to weight ratio.

Lithium-ion batteries have replaced the nickel-cadmium (NiCd) batteries that were first used to power laptop computers and the nickel-metal hydride (NiMH) batteries that superseded the NiCd laptop battery technology. They have dominated today’s rechargeable battery market for laptop computers because they are much lighter than the other types of laptop batteries, they retain their charge longer than the other technologies and because they do not suffer from the memory effect phenomenon. A typical lithium-ion battery has two times the energy density of a standard nickel cadmium battery. Additionally, lithium-ion batteries have a single cell voltage of 3.6 volts as compared to 1.2 volts per cell of nickel-cadmium batteries.

However, the disadvantages associated with lithium-ion batteries include: the possibility that a failed battery pack can ignite under adverse conditions, they are more sensitive to high temperature environments than the other battery technologies in their ability to retain their charge, they may fail if they are completely discharged, and the inherit chemistry of the battery leads to degradation with age as opposed to the stronger correlation between battery failures and charge/discharge cycles of the older battery chemistries. Lithium-ion computer batteries also require that protection circuitry be incorporated into the battery pack to monitor the battery charge and to provide safe voltage and current levels, as well as ensuring that the temperature of the battery remains in a safe operating range.

Cylindrical lithium-ion battery cells are generally tubular in shape, much like the shape of standard alkaline batteries. Several cells are enclosed in a plastic housing and the individual cells are connected in a manner to provide the proper output voltage and to maximize storage capacity (rated in milliamp-hours). Prismatic shaped lithium-ion cells are also available, but they are much smaller and are typically used in devices such as cell phones where weight and space is a prime consideration.

There are several things that affect the life of a lithium-ion laptop battery. Battery degradation is hastened by heat, so storing the battery in a cool environment will prolong its life. Manufacturers typically recommend a storage temperature of approximately 60°F for the long-term storage of lithium-ion batteries. These batteries, as stated previously, do not retain a memory from partial discharge cycles, so full discharge cycles are not required. In fact, partial cycling of the battery will help extend its life. Lithium-ion batteries do have a limited lifetime like the older battery technologies, but this is relatively independent of their charging cycles and is chiefly related to their age. A typical battery will last only 2 to 3 years. This is true even if the battery remains unused so it is important not to purchase a replacement laptop battery until it is ready to be put into service.

The author has established a website for replacement laptop batteries that provides tips and buying advice regarding cheap laptop batteries. An in-depth article on laptop battery ratings discusses the voltage and milliamp-hours specifications that are two of the chief considerations in the choice of a replacement laptop battery.

Organic chemistry is a branch within chemistry which deals with the study of chemical compounds containing carbon; their formation, their processes, properties, reactions and structure. Formerly, it was popular belief that it was very difficult to artificially synthesize compounds from living organisms. When it was realized later, that even those compounds could be treated in ways similar to the inorganic ones, in laboratories and through artificial processes, organic chemistry gained momentum.

Organic compounds are usually covalently bond which allows it to form unique structures in the form of long chains and rings. As opposed to inorganic compounds, organic compounds melt, decompose, sublime below 300 degrees. Solubility of organic compounds depends on solvent type and on functional groups. Perkin’s attempt to manufacture quinine which resulted in organic dye generated a lot of interest in organic chemistry.

Life depends on inorganic chemistry as well, and it is not always that organic compounds can be related to all the life processes taking place.

The production of organic molecules may include processes not including life. These include those enzymes that require other metals, like iron, rather than carbon. Elemental carbon and a few classes of carbon compounds are also considered inorganic. Organic compounds can be put to many uses in a number of applications. They are used in products like paints, plastics, foods, explosives and also form the basis of many natural and earthly life processes. They may even act as catalysts in biochemical reactions, owing to their varying reactivity.

The petrochemical industry was created by the discovery of petroleum and its separation into fractions. Conversion of compounds using different chemical processes also gave a boost to the petrochemical industry. To explain classification, in organic chemistry it is required that the relative arrangement of atoms within a molecule must be added for a full description. In short, organic substances are classified on the basis of their molecular arrangement and other constituents.

Compounds have been divided into functional groups and have further been distributed into sub classes. There are two major categories of compounds; namely the aliphatic compounds and the cyclic compounds.
The aliphatic compounds are further divided into 3 groups, homologous series, paraffin alkenes without any double or triple bonds or olefins alkenes with the a single or double bond and acetylenes alkenes with triple bonds. Aliphatic compounds may either be straight chained or branch chained ones which further affects characteristics like octane number or cetin number in petroleum chemistry.

Cyclic compounds maybe saturated or unsaturated. The cyclic hydrocarbons can be divided into two groups namely; salicylic and aromatics. The former type exists in the form of large rings while aromatics contain conjugated double bonds e.g. benzene.

In organic chemistry, carbon is believed to have the capability of forming certain compounds whose molecules can form a network by attaching themselves to each other. This process is known as polymerization and the chain that is formed is called polymers while monomer remains the source compound. Polymers can be artificially produced and are called industrial polymers while those occurring naturally or synthetic polymers are referred to as biopolymers e.g. Teflon, polythene, nylon etc. All these may be present in different varieties varying on the basis of compositions used to produce them.

Another important area of study that falls within organic chemistry is the bi molecular chemistry. It is of particular interest to biochemists. Biochemistry involves the study of the long chains bio polymers and amino acids, carbohydrates etc., basically, the multi-functional group molecules in living organisms. Animal biochemistry contains small molecule intermediates required to produce energy with the use of common hydrocarbons found in animals.

Fullerenes are among those compounds which have electronic properties due to their spherical structure. Organic compounds containing bonds of carbon along with nitrogen, oxygen and halogen are also classified within organic chemistry.

Organic reactions are chemical reactions which involve organic compounds and the reactions the compounds undergo are determined by the functional groups. Organic chemistry encompasses the study of all such reactions and is an applied science used in many areas of study, especially to design synthesis, analyze and put it to practical use.

Segun Olowookere recently started his own clothing company called Lowooke who speciallise in designing, producing and distributing a range of clothing aimed at the urban and youth market. The apparel that Lowooke sell is produced using organic materials that have been ethically sourced. You can view their range of Urban Clothing London at http://www.lowooke.com/shop/

Food fraud often boils down to politics or semantics. Something labeled parmesan cheese may not come from Parma, for instance. But sometimes food producers try to feed us cheap fillers and other lies. In this episode of Speaking of Chemistry, Sophia Cai explains how scientists, regulators, and food makers are relying on chemistry to make sure consumers get what they pay for.
