The exploitation of biologically active secondary metabolites for useful applications, including therapeutic drugs, is far from new. Since ancient times, nature has been recognized as an important source of potential drugs; examples of early uses and benefits of natural products for human can be found in most major civilizations (Newman et al., 2000; Constantino et al., 2004). The use of natural products for medical purposes slowly developed into the scientific field of pharmacogenosy. However, this was not until the early 1800’s when the active principles from plants were isolated and characterized. Among the first active principles isolated were morphine atropine, colchicines and caffeine (Newman et al., 2000). Morphine, atropine, and caffeine are today listed as core medicines in the World Health Organization’s “Essential Drugs List”, which is a list of minimum medical needs for basic health care systems (WHO, 2005).

Pure and 0.1 mole % L-aspartic acid doped Ammonium Dihydrogen Phosphate (ADP) have been grown by solvent slow evaporation technique at room temperature. The grown crystals were characterized by powder X-ray diffraction, Uv-visible, FTIR and Raman FTIR analysis. The doping of L-aspartic acid was confirmed by FTIR spectrum and Raman FTIR. The Nonlinear optical property (SHG) of L-aspartic acid doped ADP was increased than the Pure ADP. Thermally stable for both pure and L-aspartic acid doped ADP crystal. Micro hardness studies were carried out on the grown crystal.

Wireless body area sensors network technology provides ef?cient communication Solution to Omnipresent health-care system. Here the system is taking care of diabetes patient through the WBASN even when the patients is mobile and preserving his all test reports and prescribed medicine at server side .This system provide early detection of abnormal condition and prevention of acute consequences as well as ECG of the patient. The produced android application send alert message with his present location to the doctor as well as family simultaneously if there is any sudden ?uctuation in patients body.

Soil and Tailing samples in Dan-Kande gold mining environment were analysed with the aid of X-Ray Fluorescence technique. The long period of artisanal mining exercises in the environment calls for investigation for health benefits of critical group. Of the detected elements, It was observed that Mn, Fe, Ni, Cu, and as occurs in raised concentrations at many folds above USEPA regulatory benchmarks at the café and residential areas. There is a close correlation between the raised values obtained from the House and café samples indicating that minerals are being taking into various houses for processing. This is a potential health bomb due to explode.

The paper reports key issues associated with recent incidences of heavy metals pollution in Nigeria. Factors such as poor government policies, poverty, ignorance and inappropriate prevention and control measures are the key reasons responsible for the problem. Different diseases and subsequent deaths have been documented. For example, Zamfara lead poisoning that claimed the lives of over 500 children, and left thousands in severe health situations in 2010, is the worst of its kind in the global record of the year. To address the issue complete phasing-out of leaded gasoline and policies against illegal mining are necessary. Environmental education (especially in the rural areas) and effective poverty alleviation programmes are required to ensure good understanding of the gravity of the problem and compliance with applicable laws. Adequate funding of health sector is essential to promote training of health personals and good treatment of affected people.

A multitude of studies have been conducted to assess volatility. Since the work of Mandelbrot (1963) and Fama (1965), researchers have been designing several volatility calculation models. However, the ARCH process of Engle (1982) and GARCH of Bollerslev (1986) are the most important initiatives. Our empirical validation has studied the evolution of covariance between volatilities of U.S. indices on the one hand, and non-US indices, on the other hand, over eleven years. We found changes in covariance marked by amplifications during periods of crises. These show transmissions of excess volatility between markets, where a contagion phenomenon prevails.

In this paper, the application of homotopy perturbation method (HPM) is applied to solve nonlinear fuzzy volterra integral classes equation. Comparison are made between the exact solution and solution of homotopy perturbation method, also we proved the convergence of the solution for the nonlinear fuzzy volterra integral classes equation with high computational and complexity to find the solution by using analytical method, so we describable this solution by using Homotopy perturbation method , in Banach fixed point theory for existence and uniqueness. Numerical examples are given to represent the efficiency and the accuracy of the method and all of the results reveal that the homotopy perturbation method is very effective and simple to solve our problem . Finally using the MAPLE program version (18).

This study investigates that how corporate social responsibility affect the overall consumer behavior, that is, loyalty, repurchase intentions, and word of mouth. Authors purposed that CSR generates trust and then loyalty, repurchase intentions, and word of mouth are generated. Perceived service quality affects the relationship of CSR and trust. Results support the purposed relationships, as CSR adds up to customer’s trust and then customer become loyal to the company and repurchase intentions and positive word of mouth are also generated. The test results show no impact of perceived service quality on CSR and trust’s direct relation.

The present article discuses the problems of new Unitary Quantum Theory in its applications to the different aspects of the reality. There are spectacular examples of such applications.

Language is the means of communication among people. Gilaki language is an ancient and living Caspian language, and a member of the northwestern Iranian language branch, spoken in Iran’Gilan province. Gilaki is one of the branches of Pahlavi Ashkani language i.e. Parti, which is spoken in the north of Iran and the south parts of the Caspian Sea. Gilaki language and English language are included in the Indo-European branch of languages in language classifications. In this paper similar vocabularies in Gilaki and English languages are investigated. Among found vocabularies, some are completely similar both in terms of phonetic and semantic; some are semantically similar but phonetically different and some are phonetically similar but semantically different. And finally some words have slight differences both phonetically and semantically.
