Nitrogen Cycling in the Americas : Natural and Anthropogenic Influences and Controls
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere. The anthropogenic production of NR has been especially high in developed countries of the temperate zone, such as the USA and Canada, where severe eutrophication of estuaries and coastal zones, acidification of lakes and streams, loss of biodiversity, and reduced forest productivity have become common environmental problems associated with increasing nitrogen loads to ecosystems. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
New Vision of Multiblesclerosis
"There is an evidence that both the multiple sclerosis increased prevalence and incidence rate of over the last few decades. Therefore, the goal of our study is to highlight the causes and the risk factors of such neurological disease in order to raise the public awareness for its early symptoms to be able to treat the patients as early as possible and to have the best outcome. The symptoms of this disease are similar to some extent to other diseases so we will design a table and a test for differential diagnosis with such diseases because there is not a specific diagnostic test also taking into consideration to include in our current project A new promising medication (Radicava)which was first approved by FDA in 2015 in Japan 20 years after all old mentioned medications in this study and we started communication with a brilliant neurological doctor to plan using it first time ever in our country. Beside that we will recommend some important diet to follow for patients and some advises to avoid some risk factors which can develop this disease."
New Vision of Metformin in treating cancer
The anti-diabetic drug metformin is rapidly emerging as a potential anticancer agent. Metformin is a biguanide that is effective in treating type 2 diabetes and the insulin resistance syndromes, improves insulin resistance by reducing hepatic gluconeogensis and by enhancing glucose uptake by skeletal muscle. Metformin can reduce the incidence of cancers and can reduce the mortality from cancers, increase the response to treatment cancer cells when using radiotherapy and chemotherapy, reduce the likelihood of relapse. Diabetes can be a factor in the occurrence of various types of cancer, and develop a variety of cancers such as colo-rectal, pancreas and liver cancers, compared to non-diabetic patients. Incidence of various cancers is high among patients of T2DM due to insulin resistance and mitogenic effects caused by hyperglycemia.
New Techniques in Solid-State NMR
After the discovery of nuclear magnetic resonance, [1, 2] the new spectroscopy was used for the study of 1 H nuclei in liquids, but then the signal from copper in the receiver coil itself, the first observation of NMR in the solid state, was found.“Wide-line NMR”, named thus because of the line-broadening effects of dipolar interaction and chemical shift anisotropy, was not far behind, and soon led to significant advances through the analysis of spectral lineshapes. Inthis way Richards and Smith [3] demonstrated the presence of H3O+ cations in solid hydrates of strong acids, while Andrew and Eades [4] investigated the details of molecular motion in three solid benzenes. Even now, 50 years later, it is difficult to think of a technique which would provide a more convincing demonstration of the reality of these effects.

Neuroendocrine cells and peptidergic innervation in human and rat prostrate
Introduction The prostate causes a signi?cant number of medical problems in the adult male, and the lower urinary tract symptoms are accepted as an unavoidable consequence of male aging. Most of these symptoms are mainly due to clinical benign prostatic hyperplasia (BPH), which is the most frequent benign tumor in the male, in- pendent of race or culture. On the other hand, cancer of the prostate shows an increasing incidence, being the second leading cause of death in men, after lung cancer.

Mute people aiding application
Communication is an essential tool for human survival. It is a fundamental and effective method of sharing thoughts, needs, feelings, and opinions. However, a large portion of the world's population lacks the ability to communicate with others. Such as the ones suffering from hearing loss, speech disability, or even both. Those disabilities have a significant impact on their lives in terms of work and relationships. The majority of these people are sometimes unable to support themselves financially due to the lack of job opportunities. Given these difficulties, we have decided to develop an application to help them overcome the obstacles they may encounter in their daily lives. After consulting with two deaf and mute people we customized an application that works in two ways. One of which is to translate their sign language in real time by using mobile camera and recognizing hand motion. The other works by converting text-to-voice, and accurately expressing the user’s emotions with the help of the facial emotion recognition.
