Design and operating parameters of diesel engine were optimized in the present work with respect to performance, combustion and emission parameters. The goal is to reduce brake specific fuel consumption (BSFC), exhaust gas temperature (EGT), ignition delay (ID), emissions (CO, NOx, HC) and to increase peak pressure (PP), brake thermal efficiency (BTHE), heat release (HR) simultaneously with least number of experimental runs. The objective was accomplished through experimental investigations, design of experiments, Taguchi method and Grey Relational Analysis. Four parameters viz. injection timing (IJT), injection pressure (IP), compression ratio (CR) and load were varied at four levels and the (nine) responses were recorded. Taguchi approach was applied to individual response and observed that optimal factor settings for various responses are different.

The present study has been conducted in Serampore, West Bengal. The health of geriatric population is a present as well as future concern. This poses mounting pressures on various socio-economic fronts of the state, including pension outlays, health care expenditures, saving levels etc. This makes it necessary to look into the various aspects of their problems: Health, social rejection, economic, psychological and other allied aspects. In the traditional joint families, infirmities were taken care of by the individuals, immediate circle of relations and family members. Older people enjoyed a sense of honour and authority and had the responsibility in decision-making. However, in recent times, as a result of changing circumstances due to demographic transition, rapid pace of industrialization and urbanization, disintegration of joint family structures into unitary ones, the older people become more vulnerable to physical disabilities as a result of different morbidities and poor health seeking behaviour. This study will prove to be useful for the planners and policy makers in Government and private organizations and will help in enhancing the understanding of the problems of elderly people in the state.

The recently introduced Market Dynamics method demonstrates parallelisms between security price indicators and their physical counterparts. Specifically, the security price is viewed as a potential energy density, and events such as earnings releases as forces that affect security prices. This dynamic representation of security price movements is extended and applied towards developing an event driven approach for measuring security price movements and the associated price charts. A conservation of capital principal further underlines the central role of capital flow in the formation of support levels. This classical approach to security price movements enables access to a vast pool of existing scientific knowledge and opens new insights into analyzing security price movements with potential applications in the fields of finance and investment management.

The paper will be aimed at addressing the analysis of value chain of Sudan Dairy industry. Sudan has been facing plenty of challenges in terms of their dairy industry, it being the core earning source for their people. This importance is evident in the quantity and representation of value chain components represented by producers and industry that they are specific, without considering the distributors. The integration of markets and governmental support for the country would create an increasing standardization of demands consumers, the spread of productive activity around the world. The systematic transition in the dairy industry would begin to develop international strategies focusing on the specifics of different regions in which they operate. Therefore, a better and improved value chain procedure would positively complement the Sudan dairy industry, endowing their people with better employment opportunities too. The research approach used in the paper is based on secondary qualitative design. This approach enabled the researcher to extract relevant information regarding the topic, efficiently.

The study was conducted on The status of an Ethiopian endemic plant Vepris dainellii, in Arba Minch Natural forest, Southern Ethiopia, to determine the population status, population structure and regeneration status of the species. Systematic sampling method was used to collect data from 80 quadrats (20m x 20m) established along transects. Analysis on the structure of the species indicated that the species was under good regeneration status. Anthropogenic activities carried out in the area such as cattle overgrazing, cutting of species for fire wood, charcoal and house construction were the major threats to the species. Therefore, it is recommended that timely measures should be taken by all stakeholders to sustain utilization of the species of the study area.

When the states and properties of microscopic particles were described by linear SchrÖdinger equation the quantum mechanics had a lot of difficulties, which cause a centenary controversy in physics and have not a determinate conclusions till now. Thus we used a nonlinear SchrÖdinger equation to replace the linear SchrÖdinger equation and to depict and study in detail the states, properties and rules of motion of microscopic particles. Concretely speaking, we here investigated the properties and rules of wave-particle duality of microscopic particles and its stability, the invariances and conservation laws of motion of particles, the classical rule of motion, Hamiltonian principle of particle motion, corresponding Lagrangian and Hamilton equations for the microscopic particle, the mechanism and rules of particle collision in different nonlinear systems, the uncertainty relation of position and momentum of particles, the features of reflection and transmission of the particles at interfaces as well as the eigenvalue and eigenequations of the particles, and so on. The results obtained from these investigations show clearly that the microscopic particles described by the nonlinear SchrÖdinger equation have exactly a wave- particle duality, motions of its centre of mass meet not only classical equation of motion but also the Lagrangian and Hamilton equations, its mass, energy and momentum and angular momentum satisfy corresponding invariances and conservation laws, their collision has the feature of collision of classical particles, the uncertainty of position and momentum of the particles has a minimum, it is a bell-type solitary wave contained envelope and carrier wave, which but differs from not only KdV solitary wave but linear wave, its eigenvalues and eigenequations obey Lax principle and possess plenty of unusual peculiarities. The above natures and properties of the particles are different completely and in essence from those described the linear SchrÖdinger

M-learning systems have become the order of the day for universities in countries like Uganda to conduct studies to their students. The main attention towards M-learning is the increase in the number of mobile devices such as mobile phones, PDAs, Smart Phones, laptops, and iPads as well as enhancements in the technological capabilities of these devices. The purpose of this study was to develop a model to enhance students’ intention to adopt and use mobile learning. A number of factors have hindered the adoption and use of M-learning. Various solutions have been put forward but they have not adequately addressed the issue of adoption and use of M-learning in Ugandan Universities. In developing countries, M-learning adoption and use is also constrained by lack of information about its requirements. The need therefore remains, to determine requirements and customize existing M-learning adoption models to suit the needs of universities in developing countries.

The Genetic risk prediction strategies found in practice for coronary artery disease are not significant to estimate the scope of adverse cardiovascular events such as unstable angina and myocardial infarction. Hence in regard to this objective, this manuscript contributed a metaheuristic approach to predict coronary artery disease and the scope of unstable angina and myocardial infarction. The proposed metaheuristic is built from the gene expression data of blood samples collected from patients with coronary artery disease diagnosed, unstable angina and Myocardial Infarction. The data also includes gene expression data collected from the blood samples taken from the people clinically proven as salubrious (healthy). The relation between genes and gene expressions are considered as the state of input to devise the metaheuristic. In order to find the confidence of the relation between gene and gene expression a bipartite graph is built between them. The experimental study evincing that the prediction performance of the proposed model is substantial that compared to other benchmarking models.
