Highlights

Banking industry plays an important role in any country. They provide different types of loans and offer different types of deposits. If banks are weak, they are unable to provide loans. So this is may impact countries economy. To become banks weak so many reasons are there. One of the main reasons is non-performing assets. Non-performing assets refer to people are unable to pay the loans, at that time they become NPAS to the banks. When NPAS arise in banks; they show their impact on banks. Banks net profits are decrease. They are unable to provide loans to different sectors. So banks destruction shows so much impact on different sectors.

Highlights

The first Air conditioners and refrigerators employed toxic or flammable gases such as Chloro Fluoro Carbons (CFC’s), Hydro Chloro Fluorocarbons (HCFC’s), Hydro Fluoro Carbons (HFC’s) and ammonia that could result in fatal accidents when they leaked into the atmosphere. In an automobile, the AC system increases fuel consumption of the vehicle, which uses around 4HP (i.e. 3 kW) of the engine's power. Most refrigerants used for AC system contribute to global warming, and may also destroy the ozone layer. CFC’s, HCFC’s, and HFC’s are poisonous greenhouse gases when they are leaked to the atmosphere and 100 gm of HFC’s destroy 0.5 tons of O3 molecules. In recent years, demand for small size active cooling equipment has increased which includes TEC and water cooled heat sink. While on the other hand the passive cooling system includes heat sink and fan which is not effective enough to cope with task of cooling various electronic components. The active cooling system using TEC can be used where precise control of temperature is required. The energy conversion process which is carried out by active cooling system to absorb the heat from the surface to be cooled and reject that heat to the surrounding. Our project objective is testing and validation of TEC1-12706 and evaluating its capacity, limitations and performance to be used to produce cooling effect in R&AC system. Authors are presenting performance curve enabling the user to design the optimum number of thermoelectric module (TEM) for any required cooling system. In order to find out the capacity of single TEC we have made a prototype in which the existing refrigerants are replaced by newly emerging TEC which works on Peltier effect in AC system. TEC can be used as a generator to generate electricity by applying reverse engineering.

Highlights

Today, woman entrepreneurs represent a group of women who have broken away from the beaten track and are exploring new avenues of economic participation. Among the reasons for women to run organized enterprises are their skill and knowledge, their talents and abilities in business and a compelling desire of wanting to do something positive. Women plays prominent role for the development of economy. In India the situation is different certain superstitions, controls on women in kept in back. Women success is there in all areas like house wife, teacher, professor, lawyer, engineer, doctor, pilot, scientist, technocrats, economists, etc.., in fact, women can manage the home efficiently, and why cannot she manage the business in an efficient manner. Women entrepreneurs may be defined as, “women or group of women who initiate, organize and run business enterprises”. A research conducted in Visakhapatnam district on women entrepreneurs revealed that they are found in micro scale of operation in the trades of tailoring, beauty clinic, fancy stores petty shops, food based products readymade garments, etc.

Highlights

Metoprolol tartrate (MPT) is a selective β1 receptor blocker drug mostly administered in cardiovascular diseases. Due to the highly probable over dosage, a rapid and easy to perform method for the quantitative determination of MPT in biological matrices would be useful in its therapeutic monitoring as well as in intoxication cases. The study presents a validated method for the U.V.-VIS quantitative assay of MPT in bulk and tablet formulations at λmax of 625 n.m. with molar absorptivity of 1.705 × 103 L. mole-1 cm-1. The parameters targeted for the validation were: linearity, sensitivity, accuracy and precision. The presence of secondary amine group in MPT molecule is the basis for the proposed visible spectrophotometric method. Cobalt Thiocyanate (CTC) has been proved to be a valuable chromogenic reagent for the detection and determination of amino compounds. The coloured species formed is the coordination complex of the drug and the central metal atom of CTC, which is extractable into nitrobenzene from aqueous solution. Formation of blue coloured complex when MPT is treated with CTC due to the presence of secondary amine group in it is the basis in the present investigation. The developed method is more selective, sensitive, reproducible, rapid, cheap and simple than in most of the analogous methods. For these reasons, it can be used in routine analysis and can be applied for the determination of MPT in pharmaceutical formulaions and biological samples.

Highlights

Fluid power actuators play a vital role in the field of mechatronics. The controlling of electrohydraulic actuation system is important in the view of nonlinearity characteristics of hydraulic valves. In order to control the operation of valves, the controller should be designed as well as identification of the system is necessary to know the behavior of the system. This paper provides the derivation of transfer function for a electrohydraulic servo system by using transient response of the cylinder with respect to different set point with different loads .The performance of the system is analyzed using open loop without load, open loop with load, closed loop with load and it is observed that the performance of the system works better using closed loop. Also, in this paper the identification of the electrohydraulic servo system is done using transient response parameters and using Bode plot. It has been found that the poles & zeros of the system determined by the transient response & Bode’s Plot are nearly equal. For the transfer function derived from different conditions such as open loop, closed loop, with variable loads, the PID controller is also designed and the performance characteristics hold good with theoretical aspects.

Highlights

The major purpose of this research was to assess the security challenges in telecommunication networks, and the mechanism used by Airtel Telecommunication Company in Tanzania to protect its information. The case study research design was used because a case study is a comprehensive description and analysis of a single situation or a number of specific situations. A self-designed structured questionnaire was used to collect data from 150 respondents selected randomly from Information Technology (IT) experts, end users of the system and customers of Airtel Tanzania. The researcher collected 150 completed questionnaires. Data were analyzed using percentage, frequency and statistics. The findings showed that cultural and legal practice when dealing with security across international borders is a complex challenge in security of information system in Airtel Tanzania, and standard mechanisms used to control and protect information system of the telecommunication were Password policy system and user Authentication. It is therefore recommended by the researcher that the standard security measures such as Intrusion Detection systems (IDSs) and Biometrics should be used to deter threats to the system. The researcher also recommend that the company should extensively conduct staff training on how to use the mechanism to protect the information system of Airtel company Tanzania. The use of secure supported applications should be implemented as a mechanism to prevent accidental and intended data loss.

Highlights

Drug discovery and development from natural products are gaining highly. Organic compounds from terrestrial and marine plants have extensive past and present use in the treatment of many diseases and serve as compounds of interest both in their natural form and as templates for synthetic modification. It is known that drug is developed from various compounds extracted from medicinal plants. But the medicinal value prepared from a plant of specific region is different from that plant of other regions. The study of variation in the medicinal value obtained from these plants is a computationally intensive task. It is observed that the medicinal value is a function of molecular sequence of the plant. The DNA sequence analysis reveals that the medicinal value depends on the structure of DNA. Understanding the functions of genes is a major post-genomics challenge. Analysis of gene expression becomes necessary for better understanding of molecular mechanisms, providing clues about regulatory mechanisms, biochemical pathways and broader cellular function. The gene expression profile of a cell determines its phenotype, function and response to the environment. This seems to be a new area of research, known as herbal bioinformatics. Here a review on bioinformatics studies that have contributed to medicinal plants research has been extensively made and seen that advanced signal processing tools and computational intelligence techniques can be adopted for the analysis of DNA sequence of representative medicinal plants to draw any conclusion.
