Biotechnology, with its knowledge-intensive nature and tremendous economic potential, has emerged as one of the rapidly-growing sectors of the Indian knowledge economy today. Focusing on the practical use of biological systems to produce goods and services, biotechnology has made significant achievements in the growth and its application in the areas of agriculture, healthcare, environment, etc through R & D projects and infrastructure creation. Biotechnology seemed to have improved the conditions of Living but the way information has been communicated and the way decisions are made; affect perception and public support or opposition to a new technology. Biotechnology is not a system of farming; It reflects no specific philosophy nor is it guided by a set of principles or performance criteria. It is a bag of tools than can be used for good or evil, and lots in between. Hence, the debate over the value of biotechnology in the society is polarized and impassioned. This paper clearly evaluates the rewards of this field into the society and its disfavours from the public.

Communication is a dynamic and wide process with its ever changing roles of sending and receiving information, ideas, emotions and the working of mind. Communication is not only a word but a term in itself with multiple interpretations. Out of a number of forms, there are two very important kinds of communication, verbal and non-verbal and the relation between them is inseparable. Non-verbal communication keeps the major portion of the periphery occupied and in absence of it communication can never happen. In the era of caveman, just using nonverbal communication could help to understand the other person, but in the complex society of today both verbal and non-verbal forms of communication are needed to fully understand each other. We start taking lessons in nonverbal communication from the very starting of our life from parents and the society in which we are surviving. There is a very common perception among people that for understanding any oral message we have to concentrate and subsequently be able to understand the nonverbal elements, but in reality nonverbal communication is not as easy to understand as it seems to be. Often it is misinterpreted and because of that wrong message is understood by the receiver. Another widely accepted fact states that by focusing upon the body language of a person we can predict how he/she feels about any situation. But all that varies from context to context, from culture to culture. Studies in the field of nonverbal communication have well illustrated the fact. Since nonverbal behavior arises from our cultural common sense, we use different systems of understanding gestures, postures, and silence, emotional expressions, touch, physical appearance, and other nonverbal cues including personality. This paper focuses mostly upon the basic understanding required to be taken into consideration while understanding non verbal elements along with verbal elements in different cultural settings.

Transition metal complexes are cationic, anionic or neutral species in which transition metal is coordinated by ligands. Metals can play an important role in modifying the pharmacological properties of known drugs after coordinating with it. Stability constants of complexes also have an important role in the design of drugs for alleviation of metal poisoning. In the present study levofloxacin is used as a ligand for complexation. It is a member of fluoroquinolones group of antibiotics which is very active against aerobic Gram negative microorganism. The object of the present work is a physicochemical investigation of the interaction of bivalent metal ion [Mn(II)] with levofloxacin antibiotics and is aimed at understanding the mechanism of inhibitory or lethal effect of antibiotics against fixed types of microorganisms. The stability constants data can also be used for determination of various thermodynamic parameters such free energy (ΔG0), enthalpy (ΔH0), and entropy ΔS0. From these parameters important information about mechanism of interaction can be deduced.

India is amongst the largest irrigator countries in the world today. There is however, increasing concern about some of the irrigation potential created not brought into the functional use. System performance monitoring evaluation and diagnostic analysis are keys to appreciate the improvement or inefficiency in our irrigation projects. Therefore, exercise of performance evaluation of an irrigation system, whether a minor irrigation system or a medium/major irrigation project, requires proper understanding of the problems and potentials of that project. The potential utilization of Lift Irrigation Project Barbour Sahib is less than the average of District Una and even that of State of Himachal Pradesh.

Nanotechnology has captured the imaginations of Scientists, Engineers and Economists not only because of the explosion of discoveries at nanoscale, but also because of the potential societal implications. Nanotechnology promises to be a dominant force in our society in coming decades in roads. Today, nanotechnology is still in its infancy and only rudimentary nanostructures can be created with some control. The science of atoms and simple molecules, a one end, and the science of matter from microstructures to larger scale, on the other, is generally established. The remaining size related challenge is at the nanoscale roughly between 1and 100 molecules diameters where the fundamental properties of materials are determined and can be engineered. A revolution has been occurring in science and technology, based on the recently developed ability to measure, manipulate and organize matter on this scale. Recently discovered organized structures of matter (such as Carbon Nanotubes, molecular motors, DNA-based assemblies, quantum dots and molecular switches) and new phenomenous are scientific breakthrough that merely hints at possible future developments. However formidable challenges remain in fundamental understanding of the systems on this scale before the potential of nanotechnology can be realized.

ABSTRACT: The current study was focused and stressed on the measurement and estimation of conductivity. The conductivity of the membrane was examined at different temperature ranges (25-50 ± 0.1°C) and electrolyte concentration ranges (0.01 c (M)  0.5) using multi-meter respectively. The selectivity of membrane behaviour was inferred on the basis of conductometric studies which had a particular characteristic. Absolute reaction rate theory was applied and conducted to investigate the mechanism of transport of simple metal ions through the specific membrane. The parameters of thermodynamic parameters such as activation energy, enthalpy, entropy, and free energy were calculated using the appropriate method. The membrane resistivity for 1-1 electrolyte solutions was found to decrease in the order such that Li+ > Na+ > K+, which is in accordance with an increase in the size of cation. The activation energy increases with an increase in concentration of the electrolyte as it us directly proportional to each other. The membrane was weakly charged and the ionic species retain their hydration shell, at least partially while diffusing through the membrane pores in a gentle manner. All the values of G, H, and S were found to be positive in nature and there is an increases with an increasing temperature in the order likely to be as such K+ > Na+ > Li+.

ABSTRACT: No country can have a healthy economy without a sound and effective banking system. The Banks always remain the main participants of the financial system in any country. The Banking sector offers several facilities and opportunities to their customers and, therefore, it should be able to meet the new challenges posed by technology and other internal and external factors. With the establishment of the first Bank in India by British, the Banking sector has made rapid progress in various phrases. Before the establishment of banks, the financial activities were handled by money lenders and individuals and due to that people had to suffer a lot because of ignorance and many other reasons. So as to overcome such problems the organized banking sector was established which was fully regulated by the government. In India, Reserve Bank of India (RBI) is the main governing authority and has been bestowed with extensive powers to work as Central banking authority. The Reserve Bank of India was established on April 1, 1935 in accordance with the provisions of the Reserve Bank of India Act 1935. As it is evident that most of Indian population resides in rural areas therefore banking sector had to make a number of reforms in its working in order to survive for its existence. As from the origin of banking sector in India, continuously growth is quite evident. Nowadays Indian banking system is working very efficiently in the country. In this paper, an attempt has been made to know the history and growth of banking sector by dwelling upon its growth in various phases. This paper is a small contribution to the existing vast knowledge of banking industry and will be useful for bankers, Industrialist, policy maker and researchers. Keywords: Nationalization Movement, Liberalization, Banking Structure in India, Government policy, Growth of Banking, Regulations, RBI & functions, IBA & functions, HRM & retention of employees and customers, social, ethical and environmental aspects.

ABSTRACT: Copper is a heavy metal that can harm the human’s body through water if present in excessive amount. The presence of metal in drinking water is of special concern because of its persistence and toxicity. The elimination of copper from water is important to protect public health. Different low cost adsorbents are used to remove copper from water. The strict environmental regulation and enforcement of discharge limits require effective decontamination and purification methods for copper removal. The adsorbents proved to be beneficial because of cost effectiveness. In present review paper, copper contamination, its toxicity and its removal from drinking water using different adsorbents is depicted. Keywords: Adsorption, Adsorbents, Copper Water, Toxic.

ABSTRACT: A pot experiment was employed to examine the impact of Arbuscular Mycorrhizal (AM) fungi (Glomus mosseae and Acaulospora laevis) along with Trichoderma viride on Mentha spicata after 45 and 90 days of inoculation. Soil microbes’ effect on different physiological parameters was determined. The maximum stomatal conductance (morning and evening) was observed in the plants inoculated with G.mosseae plus T.viride after 45 and 90 days (102.3±0.45, 114.0±2.52; 134±2.00, 154.16±0.95). Likewise, higher phosphorus content in root and shoot was reported in inoculated plants over control. The total chlorophyll content was also found to increase in the plants treated with A.laevis (1.628±0.04) and G.mosseae (3.491±0.06) after 45 and 90 days respectively. The finding in the present work concludes that AM fungi along with T.viride influence the concentration of different physiological parameters.

ABSTRACT: The temperature dependence of bulk modules was given by Q. Liu & Q. He13 using fundamental thermodynamic relations. The assumption in this theory was that volume thermal expansion coefficient is quadratic function of temperature. The new expressions and formulations were also derived by Tallon14. In the present study temperature of elastic constants is based on the combination of above mentioned formulations. A method to estimate the temperature dependence of bulk modules is developed with the approximation that coefficient of volume thermal expansion depends linearly on temperature. This approximation is valid only for small expansions in low temperature range. Keywords: Elastic Constant, Temperature Dependence and Bulk Modulus.

ABSTRACT: Elastic properties of solids are closely related to many fundamental properties such as EOS, thermal expansion, interatomic potentials etc. The relatively strong covalent bonding between the constituents of intermetallic compounds like LiBC, MgB2 and TiB2 gives high Bulk Modulus in the range 150-220 GPa at high melting point nearly 3000K. This behaviour makes these compounds very interesting for studies under high pressure and high temperature. In the present study, pressure-volume relationship at different temperatures for three intermetallic compounds is given. For the low compressions the increase in pressure is low but the rate of increase of pressure increases faster as we approach the high compression region. At higher temperature, the bulk modulus decreases and, therefore, the pressure required for producing same amount of compression becomes less and less. Keywords: Intermetallic compounds, pressure, Bulk Modulus, Isotherm, parameter.
