    Academic Stress and Its Effect on Physical and Mental Health among Adolescent Girls
    (2014) Thilakam, M R
    Academic Stress refers to the pressure to perform well in examinations, which is generally manifested in a variety of psychological and behavioral problems. As a result physical and mental health has been declining among school students in recent years. Reports indicated tliat even sub-clinical symptoms of anxiety and depression can negatively influence their satisfaction and performance in life . Hence the prime objective is to study ’•''ACADEMIC STRESS AND ITS EFFECT ON PHYSICAL AND MENTAL HEALTH AMONG ADOLESCENT GIRLS'- . Purposive sampling technique was adopted among 30 students studying in Higher Secondary schools in Chennai. A structured questionnaire pertaining to the objectives of the study was framed and used. The results analysed through percentage analysis showed that majority (80%) of students faced mental symptoms of stress due to absence of sense of humour almost daily and many of them felt as if nobody is there to care for them (67%), whereas about the half the respondents (47%) had poor memory and 40 percent of the selected students could not pay attention in class due to tiredness almost daily. Nearly 47 percent of students sometimes felt lack of self confidence and poor concentration. On considering the physical symptoms o f stress , it is apparent that majority (87%) o f the selected students have revealed heart palpitations and diarrhoea /'constipation , selected students felt chest pain almost daily (83%). More than three fourth of the students (77%) had nausea/vomiting, fainting and frequent urination almost daily, and 73 percent of the selected students almost daily had breathing problems and trembling (70%). Identifying real potential with proper usage of time and energy along with strong supportive netw'ork consisting of parents at home and teachers in school could effectively bring down the symptoms of stress and promote well being among students.

    Accomplishment of highly porous-lithium lanthanum titanate through microwave treatment
    (2016) Nalini, B
    Perovskite structured (ABO,) lithium lanthanum titanate (LLTO) is a successful electrolyte reported by several scientists in the recent past. It is believed that intercalation and de-intercalation of Li ions inside solid electrolyte can be improved by increasing the porosity of the material. Hence in this research work, an attempt is made to increase the porosity of the LLTO electrolyte by rapid-microwave synthesis route. The microwave prepared LLTO is compared with the sol-gel synthesized LLTO. The prepared samples are analyzed with XRD, SEM, PL and cyclic Voltammetry studies. Morphological analysis proves that microwave synthesized LLTO contains much pores compared to the Sol-gel LLTO. A remarkable difference in its electrochemical property is also demonstrated and analysed with cyclic voltammetric studies and the results are presented.

    Acoustic Signal based Feature extraction for Vehicular Classiflcation
    (2010) Shanmugapriya, D
    Acoustic signal classification consists of extracting the features from a sound, and of using these features to identify classes the sound is liable to fit.. Different types of noise coming from different vehicles mix in the environment and identifying a particular vehicle is a challenging one. Feature Extraction is done to identify the characteristic of the vehicle. The characteristic of each vehicle will be used to detect its presence and classify its type. Six different features of the vehicle acoustic signals are calculated and then further utilized as input to the classification system. These features include Signal Energy, Energy Entropy, Zero-Crossing Rate, Spectral Roll-Off, Spectral Centroid and Spectral Flux. All these features are extracted from each and every acoustic signal of the vehicles.

    ANTHROPOMETRIC INDICES AS PREDICTIVE FACTOR FOR OBESITY AMONG FEMALE INDIGENOUS ADULT POPULATION OF PENINSULAR MALAYSIA
    (2014) Sylvia Subapriya, M
    Background : Obesity is an urban phenomenon that has spread to the rural community at an alarming rate. The study assessed the prevalence of obesity mainly among female adult indigenous community of Peninsular Malaysia. Material and Methods : A total of 222 female aboriginal adults (age >19 years) representing nine (9) villages from four districts of Perak region participated in the study. Demographic, socio- economic and education background were collected using validated, pre-tested questionnaire. Anthropometric measurements for height, weight, waist/hip circumference were taken. Body Mass Index (BMI) and Waist-to- hip ratio (WHR) were used as indices for measuring obesity. Results : Based on the cut-off point for BMI by WHO for Asian population 22.5% (n=50) were overweight and 56.8% (n=126) were obese. The presence of abdominal obesity as measured by WHR reveals 58% of the aboriginal women to have abdominal obesity. The prevalence of obesity and overweight was visibly high among the middle age group (36- 50 years) with 59% and 8% respectively followed by the age group of 51 - 65 years with 24% and 10% for obesity and overweight. There was a marked decline in obesity after 65 years. Intake of starchy foods and physical inactivity contribute to the escalating overweight and obesity among the indigenous female adult population. Conclusion : One in two women were found to be obese. Early intervention, proper dietary practices and increased physical activity have to be planned and implemented to curb this serious threat among the marginalized community.

    Anthropometric Measurements of Garment Manufacturing Workers of Tirupur, Tamilnadu
    (2013) Padmini, D S
    Anthropometric data are used for proper design of workstation, equipment, furniture and many more in order to decrease awkward postures and stresses on human body due to improper design. Mismatch between anthropometric dimensions and consumer products may cause health problems such as musculoskeletal disorders, concentration deficit, and similar problems. Anthropometric data were collected fi-om 50 male and 50 female stitching machine operators aged 18-50 years enployed in garment manufacturing units. Mean and standard deviation age o f the male workers were 29.8±7.9 years and female 29±8.1 years. Twelve anthropometric measurements for sitting posture were recorded. Body dimensions such as sitting height, eye height, mid-shoulder height, elbow rest height, upper lumbar, lower lumbar and popliteal height between both genders were found to be highly significant. All the body dimensions were found to be highly correlated with age o f the workers except for lower lumbar and hip breadth as non significant. The anthropometry data of the present study was compared with studies carried out by Gite et al. (2009), Parimalam et al. (2007) and Kabir and Ahmed (2003). It was found to be significant for majority of the parameters.

    Anticancer Activity of Methanol Extract of Green Tea against Cervical Cancer
    (2016) Santhy, K S; Geetha, B
    Identification and development of natural products used for cancer prevention have attracted a lot of attention globally. Herbal extracts with their proven potential and less side effects in therapeutics have replaced the synthetically derived drugs in modern allopathic medication system. In a low resource country like India, an inexpensive dietary chemopreventive intervention would be an attractive adjunct to existing cervical cancer prevention programs. It is observed that the studies on the relationship between cervical cancer and green I tea are limited, and the observational data are very rare. Hence, in this study an attempt was made to find out the efficacy of methanol extract of green tea against cervical cancer cells (HeLa) by in vitro model systems; and to study the DNA repair capacity of green tea extracts on cultured lymphocytes of cervical cancer patients. It was found that the green tea decreased k cell viability in malignant cells in a concentration dependent manner and the IC50 value of green tea extract was found to be 111.9 ygfml. Chromosomal aberration studies indicate that methanolic extract of green tea showed a reduction in the number of Chromatid Type Aberration i (CTA) in the experimental samples when compared to control samples. Hence, it may be concluded that since green tea could cause cell death in HeLa cells and reduce the DNA damage in cultured lymphocytes of cervical cancer patients it can be considered as a potent anticancer agent against cervical carcinogenesis.

    (2016) Santhy, K S; Srividya, M
    Cancer is a disease that knows no geographic boundaries. Despite decades of basic and finical research and trials of promising new therapies, cancer remains a major cause of jrbidity and mortality. The post genomic era has now opened new avenues in cancer treatment, vhich is contemplated to be more effective and specific for tumor cells using various methods uailablefor the assessment ofDNA damage and repair in cancer patients such as the bacterial \mes test, the scoring of chromosome aberration (CA), micronuclei and sister chromatid Exchange (SCE) in proliferating cell populations although the frequency of cells with structural iromosomal aberrations in peripheral blood lymphocytes is the first biomarker for rotoxicity that shows an association with overall cancer risk. The present investigation icompasses Single Cell Gel Electrophoresis (SCGE)/Comet assay as an alternative for {togenetic test to assess the extent ofDNA damage in breast cancer patients undergoing ferent modalities of treatment viz., chemotherapy, chemotherapy + surgery, chemotherapy Ifadiotherapy and chemotherapy + surgery + radiotherapy. The present study also comprises • reduction in chromosomal damage by the addition of pomegranate extracts to peripheral ood lymphocyte culture as a biomarker tool for DNA repair capacity of test substance. ?refore, the DNA repair capacity of Pomegranate Fruit Extract (PEE) in cultures of human ripheral blood lymphocytes of breast cancer patients was examined.

    Artifact Removal from EEG using Spatially Constrained Independent Component Analysis and Wavelet Denoising with Otsu’s Thresholding Technique
    (2012) Geethalakshmi, S N
    This paper presents a novel technique for removing the artifacts from the ElectroEncephaloGram (EEG) signals. EEG signals are influenced by different characteristics, like line interference, EOG (electro-oculogram) and ECG (electrocardiogram). The elimination of artifact from scalp EEGs is of substantial significance for both the automated and visual examination of underlying brainwave actions. These noise sources increase the difficulty in analyzing the EEG and obtaining clinical information related to pathology. Hence it is crucial to design a procedure to decrease such artifacts in EEG records. This paper uses Spatially-Constrained Independent Component Analysis (SCICA) to separate the Independent Components (ICs) from the initial EEG signal. As the next step. Wavelet Denoising (WD) is applied to extract the brain activity from purged artifacts, and finally the artifacts are projected back and subtracted from EEG signals to get clean EEG data. Here, thresholding plays an important role in delineating the artifacts and hence a better thresholding technique called Otsu’, thresholding is applied. Experimental results show that the proposed technique results in better removal of artifacts.

    Ayurvastra Revival of Holistic Science
    (2016) Ratna, U; Sudharsana Devi, R
    In the present day world, hygiene is headline news and consumers are very conscious o f textiles that are hygienic. Good hygiene is an aid to health, comfort and social interactions. It directly aids in disease prevention or disease isolation. For that revive Ayurvastra. the branch of Ayurveda medical science in clothing which is completely free of synthetic chemicals, toxic irritants and thus avoids global warming. The Ayurvedic herbs have various medicinal properties and when thev are dyed with the fabric , it gives a cooling and efficient effect. In contact with clothing, the skin absorbs medicinal qualities o f herbs. .Dveing of textiles with medicinal plants is a promising area which needs to be explored scientifically and systematically for p>uducing diversified value products. Cloth infused with herbs o f traditional Indian medicine is becoming increasingly po/nilar as the country's stressed urban workers see cures for conditions such as insomnia and eczema. Globally, as many countries have been enforcing a ban on textiles that have been coloured using chemical dyes, at the same time, textile dyed using natural vegetable dyes, especially medicinal plants, have been commanding a huge market due to their obvious advantages. The herbal textiles like yoga wear, inner wear, face towels and hand towels are available in market and have huge demand .but apart from that the technology steps forward to produce herbal finish in sports textile and that is a promising area for better environmental wellness. Rising interest o f the consumers around the globe in sustainable development, environment friendly products and nat- U f a ! healing is creating an increased demand for safe and healthy organic clothes. Encouraged by naturalists and allergy-sufferers in its infancy, the organic textile market is expanding as consumers demand products that are not only earth-friendly but hitman-friendly as wall. Because the process to manufacture textiles requires treatments that can leave chemical residue on the finished producl, just using organic fibres is not enough. The entire production process must be considered to concentrate on waste water management and by reducing pollution caused by textile dyeing using chemicals.
