Determination of cropping pattern is essential to decide whether the agriculture is subsistence or sustainable. The present study was conducted to find the cropping pattern and its determinants in the semi-arid zone of southern Tamilnadu (Thirumangalam block, Madurai district). The survey was carried out to know the existing agricultural practices and it was correlated with rainfall, temperature, irrigation facility, market prices and socio-economic conditions of the cultivators. The study revealed that sorghum was suitable crop for rainfed area and paddy was appropriate crop for irrigated area. The Olericulture (vegetable cultivation) had market support and provided promising economic profitability for the farmers of this area.Keywords

Three new, simple and sensitive visible spectrophotometric methods (A, B and C) have been developed for the determination of Mosapride Citrate in bulk drug and pharmaceutical formulations. Method A is based on the condensation of Mosapride Citrate with salicylaldehyde to form schiff's base, which was a yellow colored chromogen exhibiting λmax at 410 nm. Method B is based on the formation of pink colored chromogen obtained when Mosapride Citrate was diazotized with nitrous acid followed by coupling with α-naphthyl amine, exhibiting λmax at 520 nm. Method C is based on the oxidation of Mosapride Citrate with Fe (III) and the estimation of Fe (II) produced after chelation with potassium ferricyanide, which was a bluish green colored chromogen, exhibiting λmax at 770 nm. The Beer's law was obeyed in the concentration range of 4-20, 10-40 and 4-24 μg/ml for methods A, B and C respectively. The results of the proposed methods have been validated statistically and by recovery methods.

Three new spectrophotometric methods (A, B and C) for the determination of Cephalosporins (Cefditoren Pivoxil and Cefdinir) have been proposed. These methods are based on the oxidation of the drug with Fe (III) and the estimation of Fe (II) produced after chelation with either 1,10- Phenanthroline or 2,2’-Bipyridyl or Potassium Ferricyanide at 510, 525, 730 nm (for Cefditoren Pivoxil) and at 512, 510, 700 nm (for Cefdinir). The Beer’s law was obeyed in the concentration range of 4-20, 4-20, 2-10 μg/ml (for Cefditoren Pivoxil) and 2-8, 8-24, 4-12μg/ml (for Cefdinir) for methods A, B and C respectively. Thus results of the proposed methods were validated statistically and applied successfully to the determination of Cefditoren Pivoxil and Cefdinir in bulk and its pharmaceutical formulations without any interference from excipients.

Network diagnosis, an essential research topic for traditional networking systems, has not received much attention for wireless sensor networks (WSNs). Existing sensor debugging tools like sympathy or EmStar rely heavily on an add-in protocol that generates and reports a large amount of status information from individual sensor nodes, introducing network overhead to the resource constrained and usually traffic-sensitive sensor network. We report our initial attempt at providing a lightweight network diagnosis mechanism for sensor networks. We further propose PAD, a probabilistic diagnosis approach for inferring the ischolar_main causes of abnormal phenomena. PAD employs a packet marking scheme for efficiently constructing and dynamically maintaining the inference model. Our approach does not incur additional traffic overhead for collecting desired information. Instead, we introduce a probabilistic inference model that encodes internal dependencies among different network elements for online diagnosis of an operational sensor network system. Such a model is capable of additively reasoning ischolar_main causes based on passively observed symptoms. We can implement the PAD prototype in our sea monitoring sensor network test-bed.Keywords

Menstrual disorders are common sources of morbidity among adolescent girls and often cause anxiety for these girls and their families. To determine the patterns of menstruation as well as the prevalence of menstrual disorders among adolescent girls in south Chennai. The study employed a descriptive cross-sectional design. The data were collected from 300 adolescent girls from Out-patient clinic and In-patients of Gynaecology department, Sree Balaji Medical College and Hospital and also from schools and colleges from south Chennai. Data was collected by adopting a structured questionnaire on prevalence of menstrual irregularity among adolescent girls in the age group of 13-19 years. 300 adolescent girls completed the questionnaires in the age between 13 and 19 years. Among which 66% were from urban and 34% from rural. Girls were from socio economic status I to V and maximum in the lower middle group. The mean age of menarche was 12.3 years. BMI is significantly associated with menstrual disorders. The most common menstrual problem seen in adolescent girls is dysmenorrhea (38%) followed by HMB (27%), oligomenorrhea (21%), and polymenorrhea (11%) and hypomenorrhea of 3%. Among 300 girls,36% of girls had awareness about menstruation before menarche and 64% were unaware of it. The prevalence of menstrual disorders among adolescents girls in south Chennai is high, so, steps to be undertaken for early diagnosis and prompt treatment.Health education among adolescents and their mothers about menstrual disorders and to mitigate their effects on the social and academic lives of these adolescents should be made.Keywords

A simple, rapid and sensitive reverse phase high performance liquid chromatographic method has been developed for the determination of Mesalamine in bulk drug and pharmaceutical dosage forms. It was carried out using a mobile phase of methanol and 0.025 M potassium dihydrogen phosphate buffer (65:35 v/v) on a kromosil C18 column (250 X 4.6 mm, 5μm) in an isocratic mode at a flow rate of 1.0 ml/min. with detection at 250 nm using a UV detector. The linearity was obtained in the concentration range of 20 –100 μg/ml. The developed method was found to be accurate for the determination of Mesalamine in tablet dosage forms.Keywords
