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.

This Magnetic Braking Systems (MBS) project summary is written to explain the importance and needs of product development of MBS for vehicle (motorcycle) and MBS Learning tools by utilizing the Project Based Learning (PjBL) via eSOLMS of producing innovative product (automotive). This concept aims to improve the braking system by using magnetic concept. Its focus on 3 aspects; 1) to producing alternative product for vehicle braking system (motocycle brake system), 2) to producing learning tools in advance automotive focus on magnetic braking system, 3) to developt self-regulation of engineering students (automotive) for producing an innovative product (MBS) focus on PjBL:eSOLMS concept. This project was focus on both automotive project development and 21 century e-learning process in nature. The product producing data was analyzed using standard engineeing forms or automotive lab sheet collection data. A total of 2 product; MBS for motocycle and MBS learning tool will intering 18-25 weeks for pilot test. The finding will shows the important and needs of product research and development of MBS in future. On the other hand, the result of lab/workshop measurement and observation on the usage for the MBS on vihacle and using MBS as learning tool hopefully effected on the development of engineering students’ self-regulation. It is hoped that the MBS concept can be further developed and implemented in the engineering advance automotive and Outcome Based Education (OBE) system of Malaysia.

Assignment problem is an important subject discussed in real physical world. We endeavor in this paper introduce by using Min Max Zero Suffix Method (MMZS) is Symmetric.This method o?ers signi?cant advantages over similar methods, in the process, ?rst we de?ne the assignment matrix, apply the transpose for original assignment problem then by using determinant representation we obtain a reduced matrix which has at least one zero in each row and columns. Then by using Min Max Zero Suffix Method (MMZS), we obtain an optimal solution for assignment problem by assigning zeros to each row and each column. The Min Max Zero Suffix Method (MMZS) is based on creating some zeros in the assignment matrix and then try to ?nd a complete assignment to their Zeros.The proposed method is a systematic procedure, easy to apply and can be utilized for all types of assignment problem with maximize or minimize objective functions

The medical device industry is one of the most dynamic fields of medical progress with thousands of new products marketed every year among other revolutionized technologies. The USFDA’s Center for Devices and Radiological Health (USFDA/CDRH) governs the Regulatory oversight of the medical devices. This article presents a summary of the Warning Letters issued for medical devices by USFDA from 2011 to 2016 and a trend analysis and statistics were made, which demonstrates a clear picture of the number of Warning Letters issued for 10 categories of Medical Devices. This was done to highlight the special issues that were observed. By comparing this data to that of the recent fiscal years, Pharmaceutical and Medical Devices manufacturing firms can gain a fair picture of the FDA enforcement trends and their probable impact on both Business and industry. The study found that the implementation of quality improvement strategies such as Six sigma, Quality by Design (QbD), Total Quality Management (TQM) can minimize the number of deviations and defects which leads to reduction in 483 observations and FDA Warning Letters.: It was found that739 Warning Letters for medical devices were issued by USFDA for FYs 2011 to 2016, wherein the FY 2012 (171) issuance was more and least in 2016 (43). Adulteration and failure to implement CAPA were the major deficiencies for which the Warning Letters were issued and the number has declined by 2016.
