Stress?Strain response of sands focusing sand’s shearing stress, angle of shearing resistance, dilatancy and contraction during volumetric changes etc. is of highly research interest due to its application in soil modelling and prediction of soil hazards even in a case of soil liquefaction. In this research paper, grain size and state of compactness (loosest and densest) influence on the stress?strain response of 8 (eight) different and specific sized granular sand grain have been researched by analyzing the results of a digital direct shear test corresponding to a constant strain rate of 0.5 mm / minutes and increasing normal load (5 kg, 10 kg and 15 kg). In a bird’s eye view of the results, shearing stress (irrespective of compaction state) increases only 4 % from smaller to larger grain whereas approximately 30 % increase is discernible in dense grain than that of loose grain (irrespective of grain size). Larger sized grain possesses approximately 1.5 times more angular shear resistance than smaller size but in densest state it is about 2 times more. Authors have opined that, Though both the grain size and state of compactness (loosest and densest) affects the stress?strain response, state of compactness reveals more significant influence. In a dilation?contraction region, a loose grain contracts (18 %) while a dense grain contracts initially (15 %) but finally dilates (21 %) for an increase of size during plastic volumetric deformation of the grain.

In the context of today's socially-networked-society and the rise of social media applications like Facebook , new perspectives need to be considered. The present research explored social media by examining their potential as new venues for political participation. This research seeks how using social media (e.g Facebook) for free time affects political participation (in Chandigarh, Panchkula, Mohali and Zirakpur areas). A sample of 200 males who were staying with and away from their families in the age group of 19-23 years were administered scales of Facebook usage and political participation. Correlation and descriptive analysis were applied. Results revealed a negative correlation between Facebook usage for free time and political participation. Significant difference also emerged between the males staying with and staying away from families on using Facebook for free time.

One of the most important concerns in arid and semi-arid areas of Iran is water erosion and sediment transport. Several experimental models were used for predicting the erosion severity and sediment yield in a sub-catchment area. These models are often developed for different regions than those in which they are applied. Therefore more field data should be gathered for model calibration and, ultimately, a better evaluation of method should be undertaken. However because of insufficient and less reliable sediment yield data in Iran the objective of this study is to evaluate the output results of PSIAC model in five small catchments, Semnan Province, Iran using reliable sediment yield data deposited in reservoir constructed in the outlet of these catchments. Correlation analysis showed that Upland erosion is closely related to Specific Sediment Yield (r2= 0.86). Comparison of the amount of PSIAC predicted and observed reservoir sediment SSY indicate that model was predicted lower than observed values in one catchment (Amrovan) and higher in four other catchments but these differences are not considerable in catchment scale.

Mechanical low back pain is one of the major 21st century adversity, and 2nd leading cause of disability. Back pain is a common health problem, with more than 50% of adults bothered by it each year and 70% to 80% of adults afflicted by it at some time in their lives. Yoga offers a holistic approach to health and is now considered a form of mind-body medicine within complementary and alternative medicine. Physiotherapists are beginning to recognize yoga as a form of treatment for musculoskeletal and cardio respiratory conditions. The objective of the study was to compare effectiveness of yoga and exercise therapy in the management of mechanical low back pain. Total 60 subjects with mechanical low back pain were devided in to two groups. Yoga group and exercise group. Yoga group underwent yogic counselling, asanas, and instant relaxation technique and exercise group underwent educational talk, strengthening exercises, and supine rest. Subjects evaluated for disability and flexibility with Roland Morris Disability Questionnaire and sit and reach box test respectively. Data was collected at baseline and at 4th& 8th week. Yoga and exercise therapy both showed a significant reduction in disability and improvement in back flexibility. Yoga and exercise therapy both are effective in the management of mechanical low back pain.

Sunlight based vitality frameworks have developed as a suitable wellspring of renewable vitality in the course of the last a few decades, and are currently generally utilized for an assortment of mechanical and household applications. Such frameworks depend on a sun oriented gatherer, intended to gather the sun's vitality and to change over it into either electrical power or warm vitality. When all is said in done, the power created in such applications depends on a very basic level upon the measure of sun powered vitality caught by the authority, and along these lines the issue of creating following plans equipped for taking after the direction of the sun over the span of the day on a year-round premise has gotten huge scope in this paper. In Aden city (Yemen), the change in the execution of a sun oriented cooker amid summer was observed to be as much as 40% for higher height edge and 70% for lower rise edge, in view of the created following calculations. Besides, it was demonstrated that the measure of sun based vitality caught by a tilted gatherer could be expanded by more than 40% by modifying the tilt point on a regular premise. Two LDRs are utilized to screen the sun powered light condition. These LDR yield is interfaced to Microcontroller through transistor. The controller consistently checks the voltage level of the LDRs and works the engine to confront the board to most extreme level of force. The day/night condition is additionally checked by these two LDRs to handicap the following in night condition. The engine is driven by H connect. This paper utilizes controlled 12V, 500mA power supply. 7805 three terminal voltage controller is utilized for voltage direction. Connect sort full wave rectifier is utilized to amend the air conditioner output of optional of 230/12V stage down transformer.

This paper investigates the technical efficiencies of rubber product manufacturing industry in Malaysia. We employed Stochastic Frontier Analysis (SFA). Secondary data from 313 firms that manufacture rubber product was obtained from the Annual Survey Of Manufacturing Industries 2004 by Department of Statistics Malaysia. Variables that are included in this are such as capital (RM), labor, and energy. Results clearly show that the mean technical efficiency of manufactured rubber product industry in Malaysia is 0.70328 or 70.33 percent. Majority of the firms are also fairly efficient in the use of available resources. Some technical assistance such as training programs for the proprietors of the firms and financial support such as subsidies could be offered to boost their production level as rubber is indeed an important component of the manufacturing industry in Malaysia.

Most Ghanaian foods are made from maize. Unfortunately, certain diets made from the cereal cannot be produced without processing the maize into flour. The corn mill has been the most efficient and often used tool for grinding legumes, cereals, nuts and spices. Maize is milled either dried or soaked. Dry maize is usually milled over and over again for about four times to retain a smooth texture. It is used to prepare many delicacies in different parts of Ghana. However, soaked maize is milled only once and it is ready for use. The work was conducted to find the levels of Cd, Al, Ni, Cu, Mg and Zn in the processed flour using instrumental neutron activation analyses at the Ghana Research reactor-1 Facility. As the grinding plates of the corn mills rub against each other, there is friction as well as wear and tear. This could introduce toxic metals into the corn flour. Results showed that the corn mills had no negative effects on the corn flour as the level of the elements recorded were below the required limits. Al values in the sample ranged from 1.8 ± 0.27 mg/kg to 5.40 ± 0.81 mg/kg. Cu, Cd, Zn and Mn also recorded concentration values of ranges 0.70 ± 0.11 mg/kg to 1.50 ± 0.23 mg/kg, 4.80 ± 0.72 mg/kg to 6.40 ± 0.96 mg/kg, 0.52 ± 0.08 ?g/kg and 0.90 ± 1.35 mg/kg to 4.10 ± 0.62 mg/kg respectively. No particular process recorded consistent peak value concentrations for the heavy metals. Ni recorded concentrations within the range 26.18 ± 3.23 mg/kg to 46.42±2.53 mg/kg. However, continuous consumption could lead to accumulation of these elements that could affect the body adversely.

Collocation is one of the most problematic areas in second language learning and it seems that if one wants to improve his/her communication in another language the collocational competence should be improved. The purpose of this study was to examine the effect of applying Collins Collocation Dictionary as a concordancing tool on learning lexical collocations of Iranian EFL university students. After selecting 30 students randomly, they were divided into 2 groups: experimental group and control group. A pretest was taken from both groups at the same time. In the following week concordancing practice (task1) was given to the students in the experimental group and they were asked to work with10 lexical collocations and identify (mis)collocations. At the same time students in control group received some texts and they were asked to notice the lexical collocations. Then, posttest1 was given to the students in both groups. In the next week, the same procedure with 10 other lexical collocations was repeated and posttest 2 was administered. The results showed that the experimental group performed better on lexical collocations than the control group and their results were significant.
