Sedimento logical analysis methods to study historical events and environmental sections of these dimentary basins of the natural sciences is common. Analysis of sedimentary sections particularly Quaternaryse dements can be revealed climatic and environmental conditions of the area and uncover favorable view of the environmental conditions. The purpose of this study is Analysis of Bayazeh sediments and Chopanan sediments and explanation of their formation environment. In this study the physical properties of these diments containing Granulometry, Analysis, Calcimetry, Transparent rate, rounding rate and chemical properties, including the amount of lime, pH, EC were compared and the results indicated that Chopanan sediments were aeolian sediments and deposited in dry environment and Bayazeh sediments deposits in an aquatic environment. This causes indicate that in the past era there was a local pond in the Bayazeh.

The -expansion method is predominant and useful mathematical tool for constructing exact traveling wave solutions to nonlinear evolution equations interweaved in mathematical physics, engineering, and physical sciences. In this article, we investigate solutions to the Korteweg-de Vries (KdV) equation and the (2+1)-dimensional Zakharov-Kuznetsov (ZK) equations through the -expansion method. Abundant exact traveling wave solutions with arbitrary parameters have successfully been obtained by this method which are articulated in terms of trigonometric, hyperbolic, and rational functions.

Using fuzzy logic controller automatic braking system for automobiles is proposed. The response of the system will be simulated by using Fuzzy Logic Toolbox in MATLAB. The purpose of this controller is to brake a car when the car approaches for an obstacle at a specific range. For this, the Fuzzy Logic Controller is design using the Fuzzy Logic Toolbox in MATLAB. The system uses six rules and three membership function. The two parameters such as distance and speed will be observed. Output of the controller will determine the force of the car brake. Then PIC microcontroller is used to control servo motor based on detection pulse information to push pedal brake to brake the car and reduce the speed to maintain the safety distance between the front vehicles.

The infant feeding decision is complex and involves the influence of psychological, social, and economic factors, and health care system. This study was examining a hypothesized model of relationship between social support, knowledge, attitude, self-efficacy in influencing breastfeeding practice. Methodology: This was a cross-sectional study which measuring all variables using questionnaires. All of the scales were translated into Indonesian language and the internal consistency reliability scores (Cronbach’s alpha) were found to be above 0.7 for all scales. A total of 173 nonworking mothers with babies between 0-6 months who joined the mother support group (MSG) program participated in this study. Hierarchical multiple regression test was used to assess the influence of social support, knowledge, attitude, and self-efficacy on breastfeeding. In order to test the hypothesized model of relationship between social support, knowledge, attitude, self-efficacy, and breastfeeding practice, structural equation modeling (SEM) was used for. Results: The results showed that only knowledge has significant influence on breastfeeding practice among the non working mothers (beta= .21, p= .01). Conclusions and implications: For nonworking mothers who joined MSG program, there was only knowledge that has significant influence on breastfeeding practice. MSG may be a suitable method to promote breastfeeding among Indonesian mothers.

The research paper represents a brief analysis of physico-chemical characteristics of three different water bodies viz. earthen pond, cemented pond and lake located at Bhimtal, Nainital, Uttarakhand during winter season. Air temperature, water temperature, pH, DO, free CO2, total alkalinity, total hardness, total nitrogen, nitrite, nitrate, phosphate, ammonium and silicate were the physico-chemical parameters observed during the experimental period.

Current anticancer drug development strategies involve identifying novel molecular targets which are crucial for tumourigenesis. The molecular chaperone heat shock protein (HSP) 90 is of interest as an anticancer drug target because of its importance in maintaining the conformation, stability and function of key oncogenic client proteins involved in signal transduction pathways leading to proliferation, cell cycle progression and apoptosis, as well as other features of the malignant phenotype such as invasion, angiogenesis and metastasis. HSP90 inhibitors geldanamycin, geldanamycin derivatives and radicicol exert their antitumour effect by inhibiting the intrinsic ATPase activity of HSP90, resulting inactivation, destabilization and degradation of HSP90 client proteins. HSP90 is new therapeutic target attack on all of the hallmark traits of cancer such as self – sufficiency in growth signals, evading apoptosis, sustained angiogenesis, limitless replictive potential, tissue invasion, insensitivity to anti-growth signals. Clinical activity has been seen with 17-AAG in breast and prostate cancer. Hsp90 inhibitors have entered Phase II and III clinical trials, and have shown therapeutic activity in several types of cancer.

Mobile Ad-hoc Networks (MANET) is the self organizing collection of mobile nodes. The Optimized Link State Routing (OLSR) protocol was designed to improve scalability of Mobile Ad-Hoc Networks (MANETs). OLSR protocol implements Multipoint Relay (MPR) nodes as a flooding mechanism for distributing control information. Nevertheless, OLSR was designed without security measures. There-fore, a misbehaving node can affect the topology map acquisition process by interrupting the flooding of control information or disturbing the MPR selection process.

Economic effects of human beings have been always focused on how to obtain the best results b using the least possibilities and factors available, such tendency can be called "attainment of higher efficiency and productivity". Productivity is a comprehensive concept encompassing efficiency an increase in which is taken into account by politic and economic authorities continuously in order to promote standard of living of, welfare of, and relaxation and peace of people. Some consider survival and persistence of a politico-economic system dependent on productivity. One way to increase productivity is privatization and free trade. Present research focuses on effects of these 2 variables on each other. Subject of this research is to study effects of privatization on total productivity of production factors in in Mellat Bank and its aim is to analyze productivity after Mellat Bank was privatized in order for resulting outcomes to create clearer outlook and wider perspective in front of managers. Considering research aim and subject, this research used descriptive-analytical method. In present research, inputs and outputs of 48 Mellat Bank of Kermanshah province were studied in 2 time intervals: one related to pre-privatization time (2005-2007) and other to post-privatization time (2009-2011) of Mellat Bank. This research inputs include personnel, administrative, and operational costs while outputs include volumes of deposits, facilities, and services provided. Data was analyzed by using MalmQuist index and data coverage analysis with EMS and GAMS software. Then, hypotheses were tested by SPSS software. Research results indicate that, following privatization, total productivity index and human force productivity increased significantly and it was found that technological changes relate directly to the level of productivity so that enhanced technology level can increase productivity level.

Spices show potential health benefits, as they possess antioxidant activity. Ginger and turmeric are major spices used in Indian cooking. Effects of cooking processes on the levels of antioxidants in ginger and turmeric extracts were studied. Water and acetone extracts of raw, boiled and roasted ginger and turmeric were analyzed using FRAP assay. In the case of ginger, antioxidant activity was found to be lower in extracts prepared after boiling and higher after roasting. The antioxidant activities in turmeric extracts prepared after boiling as well as roasting were higher.

Carbonate sequence of Lar formation (Upper Jurassic) have been studied in three subsurface sections in the north east of Iran. This formation is formed of two separated units, white limestone in the upper and gray dolomite in the Lower part. This formation is overlain by yellow detrital sediments of Miocene units and underlain by siliciclastic Shemshak formation disconformably. Thirteen microfacies from mudstone to grainstone and boundstone were found in this formation. They were deposited in four facies environments; open marine, shoal, lagoon and tidal flat. Facies analysis and the absence of slump and sliding structures, reefal facies, gradual facies changes and widespread tidal flat deposits indicate that Lar formation was deposited in a shallow carbonate platform as ramp.
