Ruchika Nandha,Mahinder K. Chhabra
International Journal of Basic & Clinical Pharmacology , 2013, DOI: 10.5455/2319-2003.ijbcp20130110
Abstract: Background: Chronic headache is as much as a problem in India as elsewhere in the world with a rising trend in young adults which negatively affects the quality of life of the affected person. In current scenario of increasing prevalence of headache in students, most of them have been found to practice self medication leading to inappropriate management and sometimes analgesic overuse causing treatment refractoriness. Methods: A questionnaire based survey was done on undergraduate dental students at a tertiary care dental teaching hospital in Northern India. Severity of headache was assessed by Numeric Rating Scale. Data collected was analyzed to assess the prevalence, pattern & triggering factors of headache along with awareness of dental students regarding treatment. Prevalence and characteristics of migraine were also assessed along with the therapeutic strategies opted by students. Results: Our study (n=186) demonstrated headache prevalence of 63.9% which was higher in females (74.3%) as compared to males (32.6%). Headache experienced by majority of student population was bilateral (36.13%), sharp stabbing (38.65%) and of moderate intensity (57.98%). Common associated symptoms were nausea/ vomiting (24.36%) and scalp tenderness (22.68%). Stress (82.3%) &irregular sleep (81.5%) were the most common triggering factors. Prevalence of migraine was 13.44% with female preponderance (87.5%). Practice of self medication was reported by 88.2% of students. Most commonly used drugs were paracetamol (36.76%), aspirin (26.47%) and combination of ibuprofen and paracetamol (25%). Specific medication use in migraineurs was found to be low (25%) showing inadequate management of migraine headache in our study population. Conclusions: The results in this study demonstrate high headache prevalence in dental students with self medication being practiced by the majority. [Int J Basic Clin Pharmacol 2013; 2(1.000): 51-55]

Kavita Sekhri,Sangeeta Bhanwra,Ruchika Nandha
International Journal of Basic & Clinical Pharmacology , 2013, DOI: 10.5455/2319-2003.ijbcp20130114
Abstract: Background: As herbal therapies are increasingly being used around the world because they are perceived to be free of side effects, it is important that prescribers should be made aware of their possible harm or herb-drug interactions. In this context present study was undertaken among dental students to assess their knowledge and attitude towards the use of herbal products as medicines. Methods: A detailed questionnaire having both open and close-ended questions to assess students’ perception, awareness and usage of herbal medication was given to 90 second year students in a teaching dental hospital. Data was expressed as counts and percentages. Results: A total response rate of 93.3% was observed. 60.77% of respondents had used herbal medication for various ailments. Highest frequency of the use was recorded for ginger (37.5%) followed by neem (16.66%), turmeric (15%) and tulsi (13.33%). Elders at home (86%) was cited the most common source of herbal product information. Students were familiar with the use of clove, aloe vera, turmeric and neem but St. John's wort and Gingko biloba are ones that were generally not known to them. 67.64% indicated unawareness about safety concerns and herb-drug interactions. Most (68.65%) agreed that they did not tell their physician about taking herbal products. 58.73% preferred herbal products over allopathic medicine. Conclusions: There is a need to impart knowledge to the students about the usage of herbal products as these are frequently used to treat various health problems. Students should be sensitized about their safety concerns and potential drug interactions. [Int J Basic Clin Pharmacol 2013; 2(1.000): 71-76]

Physics , 2013,
Abstract: Some Beyond the Standard Model theories predict new particles that decay predominantly into top-antitop quark pairs. A search for top-antitop quark resonances that decay into the lepton plus jets final state is carried out with the ATLAS experiment at the LHC using 14 fb$^{-1}$ of $\sqrt{s}$ = 8 TeV proton-proton collisions. The search considers both cases where all of the final state jets are isolated and where some or all of the top quark decay products are merged into a single jet. Mass exclusion limits at a 95% credibility level are set for two benchmark models, one predicting leptophobic topcolor Z' bosons and the other predicting Randall-Sundrum Kaluza-Klein gluons.

International Journal of Organic Chemistry (IJOC) , 2013, DOI: 10.4236/ijoc.2013.31010
Abstract: A novel mediatorless reusable glucose biosensor with a remarkable shelf life has been fabricated on electrodeposited film of chemically synthesized nanostructured polyaniline (NSPANI) on indium tin oxide (ITO) coated glass plates using cyclic voltammetry. Glucose oxidase has been covalently immobilized on electrodeposited NSPANI film to fabricate a glucose bioelectrode (GOx/NSPANI-SDS/ITO). The results of linear sweep voltammetry and the high value of heterogeneous rate constant as obtained using Laviron equation indicates that GOx/NSPANI-SDS/ITO bioelectrode can detect glucose in the range of 0.5 to 10.00 mM with high sensitivity of 13.9 μA?mM?1 with a fast response time of 12 seconds. The linear regression analysis of bioelectrode reveals standard deviation and correlation coefficient of 6 μA and 0.994, respectively. The low value of Michaelis-Menten constant (Km) estimated as 0.28 mM using Lineweaver-Burke plot indicates high affinity of glucose oxidase enzyme to glucose and transfer rate. The GOx/NSPANI-SDS/ITO bioelectrode exhibits uniform activity for 12 weeks under refrigerated conditions; however the study is further going on. Attempts have been made to utilize this electrode for estimation of glucose in blood serum and results are found to be within 11% error. The unique features of this novel electrode lie on its reusability, real time monitoring, reproducibility and remarkable shelf life apart from the wide linear range, high sensitivity, low K
An Efficient Data Collection Protocol in Wireless Networks
Nandha kumar.R,P.Varalakshmi
International Journal of Ad Hoc, Sensor & Ubiquitous Computing , 2012,
Abstract: The basic idea is to implement distribute scheme in wireless sensor networks. Each node in sensor networks are deployed in a random way, so that each node will cover all the patterns related to their region. In order to increase the lifetime of the networks node with similar range which cover similar patterns are grouped into single cluster, which can interchangeably share their resource with their neighbor for overhead reduction and load balancing. Due to energy drain in sensor nodes are grouped into similar cluster and all the cluster head communicate together to form a global aggregation among sensor nodes. These in turn decrease the energy usage for short transmission to reach the centre node with estimated contact probability.

International Journal of Research in Pharmaceutical Sciences , 2010,
Abstract: A sensitive HPLC method has been developed and validated for the determination of 5-Fluorouracil (5-FU) and related substances in a novel topical formulation. The highly polar molecule requires aqueous mobile phase for the elution and separation of 5-Fluorouracil and its impurities (Impurity A, B and C official in EP). The developed method is found to be specific, reproducible, and stability indicating. The Phenomenex Synergi Polar RP 250×4.6mm 4μ column was used and mobile phase consisted of 0.1M potassium di hydrogen phosphate (KH2PO4) buffer to achieve good resolution and retention of the analyte and its impurities. The detector linearity was established from concentrations ranging from 0.01 μg/ml to 500 μg/ml for 5-Flurouracil and from 0.01 μg/ml to 0.08 μg/ml for related substances with a correlation co-efficient of 0.999. The relative response factor (RRF) values of impurity A, impurity B and impurity C determined from linearity plots were 1.9, 0.9 and 1.4 respectively. The limit of detection (LOD) and limit of quantification (LOQ) found to be in a range of 0.004μg/ml and 0.014μg/ml for 5-Fluorouracil and related substances respectively. The molecule was stable in all the stress conditions such as acid, base, oxidation, heat and photolysis as per the recommendations of ICH guidelines. The method was proved to be robust with respect to changes in flow rate, pH and column temperature. The proposed method is found to be sensitive, precise, rapid, reproducible, and offers good column life.

Gesture Technology: A Review
Aarti Malik,Ruchika
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: Body language comprises of two main parts- postures and gestures where the literal meaning of posture is static positions or poses and gestures is dynamic hand or body signs. The traditional input devices have limitations especially for those users who are uncomfortable with them. So a way out of this problem is gesture based interaction system. The main goal of gesture recognition is to create a human interaction based system which can recognize specific human gestures and use them to convey information or for device control. This paper presents a review of the introduction, types of gestures and identifies trends in technology, application and usability.
