Indian Forester, Vol 137, No 2 (2011), Pagination: 175-183Abstract
Soil resources of the coastal region of Cuddalore district of Tamilnadu were evaluated to assess the productivity rating for field crops, pastures, agroforestry, forestry and other tree crops. The soil resources were inventoried using remote sensing approach. The IRS 1D PAN merged LISS III data at 1:50,000 scale was used for pre-field interpretations. The soils mapped were evaluated for its productivity for agricultural, pasture, agroforestry, forestry and other tree crops. The texture of the soils varied from sandy to clayey due to the coastal sand dune landforms (72%). Loam (Arasanatham, Srinivasapuram and Mangadu series) and clay soil (Kondal series) occupied 16 and 3%, respectively which falls under alluvium landform. The mean pH of the soils ranged from 6.79 to 8.29. The neutral soil phase (6.5 to 7.5) was recorded in Mahabalipuram, Vandiyampalayam, Padugai, Pulavanur and Arasanatham series which occupied 58% (4905 ha) of the study area. The remaining soil series exhibited alkaline pH ranging from 7.85 to 8.29 (3688 ha; 42%). The study revealed that 71, 16 and 3 % of the area falls under Entisols, Inceptisols and Veritsols, respectively.Keywords

This research work was aimed to study the spatial and temporal changes in groundwater quality of the coastal region of Cuddalore district, Tamil Nadu. The study was conducted during 2006 for which the coastal area was divided in to three zones based on 1.5 km spatial distance from sea. The groundwater was collected from 27 representative shallow wells for the whole year with three-month interval representing different seasons. The water samples collected were characterized for its chemical composition as well as electro-che mical properties. Based on the chemical composition, different quality parameters were arrived. The results revealed that 88 per cent of the wells recorded for slightly alkaline pH ranging from 7.6 to 7.9 with electrical conductivity varying froml.l to 4.0 dS m-1. The sodium and magnesium hazard was higher in most of the wells. Seawater intrusion is the key factor, which decides the quality of groundwater in this coastal zone. Natural rainfall is the next most important factor which balances the negative effects of seawater intrusion. In total, the grolIDdwater quality of this coastal zone was poor during swnm.er and optimum during monsoon and post monsoon seasons which necessitates that sufficient care may be taken when using this water for agricuJtura1/agroforestry/fOrestry/other land use purposes.Keywords

In the last two decades, many efficient algorithms and architectures have been introduced for the design of low complexity bit-parallel multiple constant multiplications (MCM) operation which increases the complexity of many digital signal processing systems. Multiple constant multiplications (MCM) is an efficient way of implementing several constant multiplications with the same input data. The coefficients are expressed using shifts, adders, and subtracters. On the other hand, little attention has been given to the digit-serial MCM design that offers alternative low complexity MCM operations. In this paper, we address the problem of optimizing the gate-level area in digit-serial MCM designs.Keywords

Neural interfacing is a powerful means, which can develop a robust bridge between humans and machines. In this paper we emphasize on neural interfacing as an evolving trend in wireless communications by taking into account one of its important application i.e. cyborgs. In the next half of the paper we discuss the operational features of cyborgs. In an attempt to promote greater interaction between humans and computers, companies that develop cybernetic technologies participate in a variety of seductive strategies that embody the cyborg discourse. Some of these strategies persuade individuals to concede to particular philosophies, such as the argument that technical artifacts and instrumental reasoning are necessary for effective social development. With the experiments conducted and proposed to be conducted in future, and in the process given a brief description of the advantages and disadvantages of this technology.- Speaker Identification using a Novel Prosody with Fuzzy based Hierarchical Decision Tree Approach

Meaning in life is defined as the extent to which people comprehend and see significance in their lives as well as the degree to which they perceive themselves to have a purpose or overarching aim in life (Steger, 2009). According to Baumeister 1991 in our life we do face many complexities, adversity and unexpected and unpredictable situations yet many people find this experience as enriching and maintain that they have achieved their meaning in life. Frankl argued that humans are characterized by a “Will to meaning”, an innate drive to find significance in their lives and failure leads to psychological distress. Meaning in life is an indicator of well-being and facilitator of adaptive coping. The Indian armed forces is responsible for safeguarding our nation from the attacks on land and for this purpose the soldiers are constantly deployed on border and high altitude regions. They are constantly exposed to stressful environment, hence meaning in life is considered as an important psychological trait that can help them cope with this prolonged exposure to extremities so that they continue to be engaged in their work without distress. In this paper data was collected from 95 army officers and their meaning in life was gauged in terms of the dimension presence and search for meaning based on Steger's questionnaire and the influence of hierarchy, posting , marital status and birth order was statistically ascertained. Result will be discussed in the paper.Keywords

International Journal of Scientific Engineering and Technology, Vol 4, No 3 (2015), Pagination: 136-140Abstract
The main aim of our research is to design a Muffler for four stroke diesel engine. Muffler is a device which is used for reducing the amount of noise emitted by the exhaust of an internal combustion engine.In this research baffle arrangement are used to resist the flow of the exhaust from the engine. An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with carbon monoxide or other poisonous exhaust gases if they are not properly vented to the outdoors. Also, the gases from most types of machine are very hot;the pipe must be heat resistant and it must not pass through or near anything that can burn or damaged by the heat. A chimney serves as an exhaust pipe in a stationary structure. For the internal combustion engine it is important to have the exhaust system "tuned" optimal efficiency.
Mufflers are installed within the exhaust system of most internal combustion engines, although the muffler is not designed to serve any primary exhaust function. The muffler is engineered as an acoustic soundproofing device designed to reduce the loudness of the sound pressure created by the engine by way of acoustic quieting. The majority of the sound pressure produced by the engine is emanated out of the vehicle using the same piping used by the silent exhaust gases absorbed by a series of passages. And chambers lined with roving fibre glass insulation and/or resonating chambers harmonically tuned to cause destructive interference where in opposite sound waves cancel each other out. An unavoidable side effect of muffler use is an increase of back pressure which decreases engine efficiency. This is because the engine exhaust must share the same complex exit pathway built inside the muffler as the sound pressure that the muffler is designed to mitigate.

A field experiment was conducted in theri soils of Tamil Nadu to study the effect of various organics and inorganic fertilizers on the yield and quality of groundnut. Six different organics viz., raw coir pith (RCP), composted coir pith (CCP), goat manure (GM), farm yard manure (FYM), poultry manure (PM) and bio-digested press mud (BDP) were utilized using groundnut var VRI 2 as a test crop. The result indicated that application of recommended NPK+BDP @ 7.5 t ha-1 produced the maximum pod yield. The highest oil yield was recorded in the treatment receiving recommended NPK+PM @ 5 t ha-1. The BDP application in combination with recommended NPK significantly improved the quality of groundnut oil compared to other organics applied. The significant increase in soil available nitrogen, phosphorous and potassium was observed in all treatments that received organics and inorganic fertilizers. There was no significant improvement in organic carbon as well as physical properties of the soil whereas physico-chemical properties such as soil reaction and electrical conductivity were significantly influenced by various INM treatments.Keywords

Meeting the food grain demand of ever growing global population is the big challenge to agriculture sector. Plant disease significantly reduces the production of food crops besides affecting the quality adversely. Losses associated with plant diseases in yield reduction ranging from slight to catastrophic depending upon varying factors. Literature review highlighted that an average yield loss of 42% from the six most important food crops. It is vital to manage plant diseases to avoid the yield loss, which helps to meet the food grain demand in simple means. In other way, disease management is helping us to meet the food grain demand of increasing population under shrinkage of cultivable area.- Practices and Awareness of the Paediatricians Regarding Syrups and Sugar Free Medicines in Chennai City

The demand of medical devices has risen globally, especially in Europe. The devices regulated in Europe must ensure the safety and effectiveness of these products. There are various principles to approve the medical devices in the European market. The biggest companies are in Germany (27%), UK (11%), Italy, Switzerland, Spain and France (16%). The Europe has very good gobal impact in medical device marketing. The classification is based upon risk management, the medium and high risk requires the conformity assessment (CE marking) done by Notified bodies. There are four levels of classification of devices. Various EU directives that has impact on medical devices. International medical device regulatory forum (IMDRF), is followed by regulatory department of countries like Austrila, Brazil, Canada, China, EU, Japan, the United States, and WHO. The approved medical devices in European market must ensure the best protection of patient health. The development timelines for Noval drug and chemical entity take much longer time compared to medical devices. There are about 500,000 life supporting machines in which 20,000 are of generic group. Various rules on clinical evaluation and clinical investigation help in strengthening the regulatory system in Europe. To explore in marketing level premarket testing and postmarked vigilance is required.Keywords

Background: Procrastination is considered problematic when it affects normal day-to-day functioning. It can serve as a deterrent among undergraduate dental students both for their academic and career growth. Behaviour modifications are required to change this negative behaviour and Sense of Coherence is one such approach. Aim: To assess the relationship between Sense of Coherence and Procrastination among a group of undergraduate dental students in Chennai city. Material and Methods: A cross sectional questionnaire study was conducted among 358 undergraduate dental students. Thirteen item Sense of Coherence scale and Lay’s Procrastination scale were used to collect data about Sense of Coherence and Procrastination among undergraduate dental students respectively, using google forms. One-way ANOVA and Independent T test were used to test for difference in mean scores between groups based on year of study and gender, respectively. Pearsons correlation coefficient followed by Simple Linear Regression was performed to test for association between Sense of Coherence and Procrastination. Results: The overall mean Sense of Coherence score of the study participants was 49.52 ± 8.13. The overall mean Procrastination score of the study participants was 56.58 ± 10.02. Pearson’s Correlation Coefficient revealed a negative correlation (r = -.255) between Sense of Coherence and Procrastination (p = .000) indicating that with an increase in Sense of Coherence, Procrastination decreases. In tandem, the third year students with lowest Sense of Coherence score showed highest procrastination. Conclusion: Procrastination is negatively associated with Sense of Coherence and hence behaviour modification interventions based on Sense of Coherence are required, to be customized and incorporated in dental curriculum to reduce procrastination among undergraduate dental students.Keywords

Hyperlipidemia is characterized by excessive levels of lipids (cholesterol and triglycerides) in the blood. Elevated plasma concentrations of distinct lipid and lipoprotein fractions are key risk factors for Cardiovascular Disease (CVD). Natural ingredients have long been used to treat and prevent cardiovascular issues. Much research on natural compounds that are effective against hyperlipidemia has been done in recent decades as of interest. PubMed, Science Direct, Google Scholar, and Scopus are the search engines used to collect information. We picked anti-hyperlipidemia, atherosclerosis, and therapeutic plants as search terms. The goal of this article is to offer a rapid summary of herbal treatments used to treat and prevent atherosclerosis based on anti-hyperlipidemic action. This research aimed to analyze the anti-hyperlipidemic effectiveness of medicinal plants that have been scientifically demonstrated to be helpful.
