The field experiment on the influence of three legumes (groundnut, cowpea and soybean) on the agricultural yield and monetary income of an association of six crops (cassava, plantain, sweet potato, maize, rice and/or groundnut, cowpea, soybean), was conducted during two successive cropping seasons in a forest region of the DRC (Bengamisa). The results show that: - The crop association with cowpea numerically improved the agricultural yield of the components, the overall agricultural yield of the association and induced a better overall LER compared to the association with groundnut and soybean. - The crop association with groundnut, on the other hand, yielded a much higher gross margin of $2645.4/Ha, compared to the gross margin achieved by the association with cowpea ($1872.4/Ha) and that with soybean ($1847.6/Ha). - In the crop associations in this environment, cowpea is considered to be a factor in improving crop yields, while groundnuts are considered to be a factor in improving cash income.

The global financial meltdown has propelled the leading Indian IT giants towardsinnovative management strategies. This paper examines the way Infosys Technologies Ltd. is able to withstand impact of GFM by adopting innovative management practices. The paper makes an attempt to enumerate some of the best management practices do adopted by Indian IT giant. The continuous downward moving  bottom-line of IT companies has made most of them to initiate various measures which mainly comprises of uncalled for measures such as lay off, reduced pay package, etc. Such undesirable measures could be detrimental to the employees, corporate image, productivity and efficiency and society at large. The innovative practicesadopted by Infosys Technologies Ltd are tabulated under different areas of decision making which comprises of Pricing, Human Resource Management, Customer Services, Marketing, Innovation & Transformation, Cost Cutting, etc. The above said practices can be a ways to beat economic downturn and may be of tremendous help in enhancing and building business competencies for future growth. The study is descriptive in nature, which fundamentally aims at studying innovative management practices adopted by Infosys Technologies Ltd, and to draw conclusion aboutinnovative management practices. Based on conclusion drawn suggestions have been made.

This work focused onan integrated approach of solutions to improve the combustion of Jatropha oil in an indirect injection Diesel engine (Lister type). The improvements were assessed using combustion parameters, especially cyclic dispersion.The Jatropha oil was preheated to 100°C and the Diesel engine has receivedchanges in fuel injection timing and injection pressure variation. The overall engine performance (specific fuel consumption, thermal efficiency and exhaust gas temperatures), cyclic dispersion, ignition delays obtained with Jatropha oil and Diesel fuel were compared. The results show that for the performance, the injection timing of 20 Crank Angle (CA) Before Top Dead Center (BTDC) and the injection pressure of 170 bars are the settings adapted for both fuels to the different engine loads. The results also show that cyclic dispersion could be used as a very good tool for assessment of adequateoperating conditions of this type of engine, even at low loads. The cyclic dispersion is low with coefficients of variation of the indicated mean effective pressure (COVIMEP) whose values are less than 10%. The lowest values of the COVIMEP are obtained when the injection settings are 20 CA BTDC and 170 bars.

Digital elevation model (DEM) is used to determine the drainage networks involving the size, length, slope and similar features of the basin and sub basin features related to the water resource. Most importantly the hydrological analysis to be effective if the slope, area, direction, flow length, runoff length could be better reached through DEM. Scattered hydrological models clearly suggest the spatial variability of the physical properties of the basins. In this study, the characteristics of the Kottakarai Aru water shed located in Ramanathapuram district nearer to the Bay of Bengal are explained through the digital elevation model (DEM)for a detailed study of the drainage networks.

The present paper pinpoints on not-so-very-important activity in today’s competitive era i.e. free play. There is a tremendous amount of change seen in today’s child in comparison to children almost a decade ago. Most importantly, the population for whom the paper is emphasized is children, which are particularly invaluable as they transit from one stage to another and that too so swiftly that their play time has declined, and how this lack of play affects their cognitive, physical and emotional development, eventually leading to rise of anxiety, depression and problems of attention and self control. Hence, there is a need for parents, child psychologists, paediatrics as well as school management to play a pro-active role in extending the time spend on play i.e. simply free play in order to produce effects such as cohesion, harmony and well-being among children.

Glomus tumors are rare benign tumors, they represent 1 to 4.5% of hand tumors developing from Masson's glomus, a neuromyo-vascular structure of the body that participates in thermal regulation. Delay in diagnosis is frequent, because this tumor can’t give an elementary lesion, and only manifest itself by a throbbing paroxysmal pain, which misleads the practitioners, thus referring the patients in psychiatry The definitive diagnosis is based on the pathological examination. The aim of our retrospective study was to assess the value of MRI in the diagnostic management of digital glomus tumors.

Well-being includes many aspects such as happiness, energy, leisure, peace with oneself, contentment and sensitivity to the environment. It is a sense of balance between different aspects of life - from physical to emotional to spiritual and the much researched psychological well-being. The domain of the psychological well-being lies in the everyday experiences of people. To say the Internet is an important component of human life is a statement that is not exaggerated. Typically the human race would come to a standstill or become non-existent without the usage of internet, be it in mobile /computer to surf and check Facebook, Whatsapp, and other social media. A report by UK’s chartered institute of IT (BCS) found that 35,000 people who use the internet reported that it made them feel happier and better about their lives (BCS, 2010). Happiness is a gregarious feeling and is usually multiplied with better communication channels and robust interaction among people leading to an integrated well-being in individuals. Technology in the form of Internet helps in a large amount of communication and interaction, which can happen in a minuscule time. The purview of the present research is to analyse the relationship between Internet Addiction and Happiness in relation to Well-being. The sample consists of 150 Internet users both male and female. Internet Addiction Test (IAT; 1998) by Dr. Kimberly Young and The Oxford Happiness Questionnaire (OHQ; 2002) by Peter Hills, Michael Argyle were used to measure Internet addiction and Happiness respectively. The results thus obtained were subjected to statistical analysis.

In this manuscript we will show what are the Laplace transforms. What is their relationship to differential equations? Where we will explain some general examples of this relationship through a brief explanation of some applications. This will be clarified through the articles of the manuscript as below.

In the current study, thermoplasmonic characteristics of Moscovium nanoparticles with spherical, core–shell and rod shapes are investigated. In order to investigate these characteristics, interaction of synchrotron radiation emission as a function of the beam energy and Moscovium nanoparticles were simulated using 3D finite element method. Firstly, absorption and extinction cross sections were calculated. Then, increases in temperature due to synchrotron radiation emission as a function of the beam energy absorption were calculated in Moscovium nanoparticles by solving heat equation. The obtained results show that Moscovium nanorods are more appropriate option for using in optothermal human cancer cells, tissues and tumors treatment method.

Experimental and numerical investigation of the thermal conductivity in particulate filler filled (wood dust) epoxy composites have been studied in the present work. The thermal conductivity of particulate filled polymer composite is calculated experimentally using guarded heat flow meter method in accordance with ASTM-E 1530 standard. This study shows that the incorporation of wood dust results in reduction of conductivity of epoxy resin and there by improves its thermal insulation capability. Further the thermal conductivity of particle filled composites has been calculated numerically using the microstructure images by identifying each pixel with a finite difference equation and accompanying appropriate image processing. It has been observed that numerical results, experimental values and all other models are close to each other at low particulate content. On comparison, it has been found that the errors associated with the numerical values with respect to experimental ones lie in the range of 3.4 to 14.8%, the same results from Rules-of- mixture and Maxwell’s correlations lie in the ranges of 3.4 to 29.2% and 4.2 to 46.7% respectively. The incorporation of glass fibre in wood dust filled epoxy resin reduces the thermal conductivity further. With addition of 6.5vol%, 11.3vol%, 26.8vol% and35.9vol%of wood dust and 9.6vol% glass fibre the thermal conductivity of epoxy resin dropped by about 43.6%, 47.5%, 60.3% and 62.8% respectively.
