Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Since ...

Adult Hippocampal neurogenesis has often been associated with hippocampus-dependent learning memory. The whole process of neuron development is highly and differently susceptible to various factors and conditions that affect its survival, as well as functionality. Various prior researches have indicated that spatial training occurring 6-10 days after an injection of bromodeoxyuridine (BrdU), which is a DNA synthesis marker, increased the cell’s survival rate in male rats. However, sex differences has been reported in spatial cognition and hippocampal neurogenesis, hence developing difficulties in understanding whether spatial training would affect males and females hippocampal neurogenesis similarly.
Therefore, the article by ...

Definition and reaction to video

Epigenetics refers to the study of changes in organisms where those changes are caused by modifications of gene expression and not alterations of the genetic code. The video on “PBS Nova ScienceNOW Epigenetics” from YouTube, gives the numerous ways in which epigenetics is manifest in the lives of identical twins. It uses real life cases of numerous twins from diverse ages to assert that differences that exist between identical twins especially on behaviour and mannerisms are a result of epigenetics.

Sjogren Syndrome(SS) is an autoimmune disease that causes lymphocytic infiltration of exocrine glands, primarily lachrymal and salivary glands. Simply put, it is a chronic immune disorder in which white blood cells of the patient attack saliva and tear glands. At times, glands that keep the vagina moist are also attacked resulting in vaginal dryness.
In normal cases, humans' immune system generates antibodies to attack harmful material as virus and bacteria. Putting the cart before the horse, the immune system in SS patients starts producing autoantibodies and autoreactive cells that start attacking those very body parts that they are ...

Caffeine is a compound that has a molecular formula of C8H10N4O2 and is commonly known as methylxanthine [1]. The systemic name of caffeine is either 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione or 1,3,7-trimethyl xanthine. Other names that are used to refer to caffeine include mateine, theine, coffeine, and guaranine. It is a chiral molecule and has no stereoisomers. The caffeine compound has two groups of amide that predominantly exist as zwitterionic resonance structures. In these structures, the atoms of nitrogen and carbon are bonded through a double bond to one another making the two nitrogen atoms are basically planar. This results in a ...
