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.

Different organic solvent and aqueous extracts of leaf, stem bark and root bark of Annona squamosa L. were subjected separately to test their antibacterial activity by in-vitro methods like Disc diffusion method, agar well diffusion method and Minimum Inhibitory Concentration method. The extracts of Annona squamosa L. shows a wide spectrum of antibacterial activities. The chemical compounds present in the experimental plant are biologically active and inhibit the growth of human pathogenic bacteria. Four species of bacteria were selected for the present study. Among them one is gram negative (Escherichia coli) and other three are gram positive (Bacillus subtilis, Bacillus megatherium, Bacillus cereus). The experimental results obtained justified the folk use of this species as a cicatrizant and vulnery agent.

This proposed antenna is used for GSM, satellite and wireless communication in, L Band. Achieved 63% reduction of geometrical area of the antenna for L –Band, achieved 57% -10dB impedance bandwidth of L Band.

Tree height-diameter relationship can be used as an important input component in forest growth and yield models and description of stand dynamics. Five non-linear growth functions were fitted to tree height-diameter data of 21 years old Gmelina arborea plantation in Ibadan, South west Nigeria. The data consisted of three sets: 2004, 2008 and 2011 on total tree height and diameter at breast height (dbh). According to the model statistics, the five growth functions fitted the data equally well, but resulted in different asymptote estimates. Modified exponential fit was observed to give the best fit for the three data sets based on least square error, coefficient of determination and significance. The models are: Ht = (R2 = 36.21%), Ht = (R2 = 37.53%) and Ht = (R2 = 34.74%) for 2004, 2008 and 2011 data sets. The predicted values follow the same nonlinear pattern and formed close to the line of best fit without much outlier. The result of this study revealed that the ability of dbh in determining height is not strong enough based on the model’s goodness of fit and the model’s ability for predictive purposes. Hence, more variables such as age, crown area and soil fertility were recommended to be incorporated in future prediction of the tree height in the study area. Also, the potential tree height-diameter equations should be evaluated and validated for their predictive capabilities across a range of tree diameters. This useful information can help forest researchers and managers to select and apply the appropriate models.
