Design Architecture-Based on Web Server and Application Cluster in Cloud Environment

Cloud has been a computational and storage solution for many data centric organizations. The problem today those organizations are facing from the cloud is in data searching in an efficient manner. A framework is required to distribute the work of searching and fetching from thousands of computers. The data in HDFS is scattered and needs lots of time to retrieve. The major idea is to design a web server in the map phase using the jetty web server which will give a fast and efficient way of searching data in MapReduce paradigm. For real time processing on Hadoop, a searchable mechanism is implemented in HDFS by creating a multilevel index in web server with multi-level index keys. The web server uses to handle traffic throughput. By web clustering technology we can improve the application performance. To keep the work down, the load balancer should automatically be able to distribute load to the newly added nodes in the server

ENSURING RIGHT TO FREEDOM OF SPEECH AND EXPRESSION ON CYBER SPACE AS AGAINST STATE INTERVENTION - INDIAN EXPERIENCE

While Internet has been extremely advantageous in connecting people and providing a platform for expression of  one’s views and opinions, on the other hand it has even at times lead to abuse of this platform by some necessitating legal regulation. Freedom of speech and expression being a fundamental right is legally enforceable even against the State and its agencies but the same can be legally restricted under certain ‘reasonable grounds’. This paper aims to analyse the existing law framework in this regard, with the object of identifying legal provisions which on one hand protects freedom of speech and expression on cyber space and on the other hand, the legal restrictions imposed for such freedom. Though the paper makes a brief assessment of the concerned legal aspect from international perspective in brief, it focuses largely on Indian law framework in this regard

The influence of soil properties and lime upon nutrient content and yield of alfalfa and lespedeza

Application of lime to acid soils as a part of soil management has probably been practiced for 3000 years at least. Edmund Ruffin, a practical farmer from Virginia, was perhaps the pioneer in the application of lime in this country. In the humid regions of the advanced countries in the world, liming has been accepted today as one of the essential practices in the profitable farming and efficient soil management. A large amount of work has been conducted on this topic, many data have been accumulated and countless numbers of articles, research papers and other publications have been written on this vitally important subject. Considerable progress has also been made in the techniques used for estimating the lime requirement for various soils. The most primitive methods like the use of litmus paper and other similar tests have given place to the modern procedures like the use of pH meters, buffer solutions and other refined techniques which are more precise and at the same time are sufficiently rapid for use on mass scale. The concept of the cause of soil acidity has undergone modification during the past few years and the significance of exchangeable aluminum as a major cause of acidity has been brought to the forefront. In spite of the fact that soil acidity is a problem of agriculture and not withstanding the large magnitude of research carried out on the subject, it is so complex that the exact nature of the whole situation is still not understood. Considerable amount of research is needed before predictions can be made precisely and with considerable rapidity as to the exact requirement of lime for a particular crop under a specified set of soil and management conditions. This study was undertaken with the following objectives in mind: 1. To characterize selected soils and evaluate the influence of certain soil properties on the lime requirement of these soils. 2, To determine the effects of the rate of lime application on the yield and composition of alfalfa and lespedeza on the selected soils

Green cement based material optimization for additive manufacturing in construction

The rapid growth of 3D printing technology has led to the development of large-scale 3D printers that can print concrete. The process of 3D printing in concrete does not use formwork and thus gives increased flexibility to designers, saves the cost of labour and materials and reduces waste. These printers have been used to construct structural elements and full-scale buildings which have been the focus of a new age of 3D printers in the construction industry. The materials are an important part of the printing process, aiming to obtain a particular mix satisfying all the requirements of cementitious material. There is interest to broaden the focus on waste from construction industries and involving these wastes in 3D printing for sustainable construction, blending technology with the construction process. In this work, stone sludge was used as raw material in the mortar, having the objective to do 3D printing in a cost-effective and affordable way. The mortar was printed using a robotic arm with an extrusion printing process. Six mortars with different proportions of stone sludge and admixtures were tested in a systematic way to determine the printable properties of mortar. The bending and compressive strength of printed or casted samples were measured and compared

A methodology to model physical contact between structural components in NASTRAN

Two components of a structure which are located side by side, will come in contact by certain force and will transfer the compressive force along the contact area. If the force acts in the opposite direction, the elements will separate and no force will be transferred. If this contact is modeled, the load path will be correctly represented, and the load redistribution results in more realistic stresses in the structure. This is accomplished by using different sets of rigid elements for different loading conditions, or by creating multipoint constraint sets. Comparison of these two procedures is presented for a 4 panel unit (PU) stowage drawer installed in an experiment rack in the Spacelab Life Sciences (SLS-2) payload

Chlorpyrifos Induced Region Specific Vulnerability in Rat CNS and Modulation by Age and Cold Stress: An Interactive Study

Chlorpyrifos (CPF)​, an organophosphorus insecticide is known to cause ill health in non-​target animals by inducing oxidative stress. In this study influence of cold stress (15°C and 20°C) and age as modulating factors on CPF induced oxidative stress was addressed to assess age-​related differences and vulnerability in central nervous system of rats. The results indicated an interaction with age and cold exposure resulting in marked decreased activity levels of SOD (P < 0.05)​, CAT (P < 0.05)​, GPx (P < 0.05)​, GST (P < 0.05) followed by increased MDA (P < 0.05) and decreased GSH levels (P < 0.05)​. The ANOVA and Post-​hoc anal. showed that antioxidant enzymes decreased significantly (P < 0.05) on CPF exposure. Moreover synergistic action of CPF and cold stress at 15°C caused higher inhibition on comparison with CPF and cold stress alone and together at 20°C indicating the extent of peroxidative damage in discrete regions of CNS. Further this study showed young individuals to be more sensitive than adults

Changing trends in the incidence of caesarean section after a district hospital became medical college teaching hospital at Karwar, a coastal city in Karnataka-an eleven years retrospective audit

Background: Caesarean section (C-section) delivery has well established risks and adverse consequences. Every health care sector should look into the standards of maternal services it is providing. This audit look into the standards we have been providing at KRIMS Karwar with a comparison to national standards.Methods: This is a retrospective audit conducted by obstetrics and anaesthesia departments at KRIMS Karwar, Karnataka. Objectives were to look into incidence of C-sections, kind of anaesthesia used and maternal mortality. In addition, to look into any change in the obstetric care/outcome after Karwar district general hospital upgraded to a medical college teaching hospital. WHO guidelines for obstetrics care were set as standards. Retrospective data for the period between January 2007 and December 2018 has been collected and analysed.Results: Total number of pregnant women admitted for labour was 13431 with an average of 1221 per year. Proportion of caesarean delivery per hundred labouring women was 16.8 % in 2007 with significant increase to reach 51% in 2012. This has decreased in subsequent years to reach 23.5 in 2018. 99.9% of the C-sections have been done under spinal anaesthesia. There was one death of the mother subjected for C-sections in 2009.Conclusions: Incidence of C-sections was alarmingly high. Implementation of the uniform protocol has significantly reduced the C-sections rate. This reduction could be attributed to the upgrading the Karwar district hospital to a medical college teaching hospital. Protocol based practice will be continued and measures to improve overall maternity services will be implemented as per the WHO guidelines
