International Journal of Green Pharmacy , 2010,
Abstract: The three chilli (Capsicum frutescens L.) cultivars viz. chilli DARL 210, Chilli Long Black and Sartoria were grown in middle hill climatic conditions of western Himalayas at an altitude of 5,500 feet above the sea level. The variation in total capsaicinoids (Capsaicin and dihydrocapsaicin) was studied from budding to full maturity stage of fruits. The fruits were harvested at every fifteen days interval from flower budding (stage zero) to full maturity stage (stage seven). The total capsaicinoids were evaluated with the help of HPLC. It can be concluded from the study that, to achieve maximum pungency (total capsaicinoids) in these cultivars, the chilli cv. DARL 210 should be harvested at the stage of full maturity (after 105 days). Whereas, Chilli long black should be harvested after 75 days and cultivar Sartoria in between 60 to 90 days from flower budding stage. As far as pungency among these cultivars is concerned DARL 210 was the most pungent followed by Chilli Long black, while Sartoria was found least pungent cultivar.

International Journal of Computer Science Issues , 2011,
Abstract: To implementation of mobile ad hoc network wave propagation models are necessary to determine propagation characteristic through a medium. Wireless mobile ad hoc networks are self creating and self organizing entity. Propagation study provides an estimation of signal characteristics. Accurate prediction of radio propagation behaviour for MANET is becoming a difficult task. This paper presents investigation of propagation model. Radio wave propagation mechanisms are absorption, reflection, refraction, diffraction and scattering. This paper discuss free space model, two rays model, and cost 231 hata and its variants and fading model, and summarized the advantages and disadvantages of these model. This study would be helpful in choosing the correct propagation model.

International Journal of Computer Science Issues , 2011,
Abstract: Color based image retrieval is an important research area in digital image processing and Color is the useful property of the image. The challenging task is to find an efficient and accurate color images similar value and some limitations between two different types of image are matching such as compressed color image and RGB color image, RGB image and HSV color image, color image and 90 degree rotate color image but this matching technique remove these problems. This paper Proposed, a new matching technique to find the similar value between query color image and database color image using histogram, spatiogram and bins . This method uses RGB and HSV color space. This is a new matching technique based on histogram and spatiogram, spatiogram is a generalization of histogram.
Towards more effective strategies for management of diabetes in Mauritius  [PDF]

Abstract: Over the past 2 decades, the prevalence of diabetes in Mauritius has remained one of the highest in the world with no recent significant improvement. Mauritius ranked 2nd in 2002 and 4th in the world in 2009 with nearly one in five of its adult population above the age of 30 years being affected. Nearly half of those affected do not know that they have the disease and this adversely influences quality of life, risks of complications as well as morbidity and mortality. Despite the availability of free health services, over 50% of diabetes patients are poorly controlled and the risk of complications from diabetes such as cardiovascular diseases, renal failure, blindness, peripheral vascular and neurological diseases leading to lower limb amputations, remain very high. Despite continued efforts from the Ministry of Health and Quality of Life (MOH & QOL) to provide easily accessible diabetes care to all patients, the outcome remains poor. Most of the outpatients and primary health care centres are overcrowded and the set-up does not provide optimal care and attention. Diabetes care is very much medical-orientated and the health promotion campaigns have had little impact so far. Prevention and control of diabetes must become a priority. There is an urgent need for enhanced heath promotion and education, as evidence suggests that a change in diet and lifestyle can bring about significant improvement in the incidence and prevalence of diabetes. This paper examines some of the key actions/ proposals with respect to: evaluation of actions taken, health promotion campaigns, attitude and behavioural change, focused leadership and commitment, marketing strategies, effective segmentation and targeting.
Evolutionary Development of Molecular Tools in the Diagnosis of Mycobacterium tuberculosis: A Review
Rahul Shrivastava,Ram Prakash Punde,Hemant Pandey,R.M. Samarth
Journal of Medical Sciences , 2010,
Abstract: Nucleic acid amplification technologies such as PCR are revolutionizing the detection of infectious pathogens such as tuberculosis (TB). Amplification technology offers the potential for the diagnosis of TB in a few hours with a high degree of sensitivity and specificity. However, molecular assays neither replace nor reduce the need for conventional smear and culture, speciation and antibiotic sensitivity assays. It is likely that future detection systems may be sufficiently sensitive to detect small numbers of pathogens without any amplification. Whatever the format and instrumentation for the assays, the impact of molecular testing on patient care will be substantially greater in the future.
A Note on Convergence of a Sequence and Its Applications to Geometry of Banach Spaces  [PDF]
Hemant Kumar Pathak
Advances in Pure Mathematics (APM) , 2011, DOI: 10.4236/apm.2011.13009
Abstract: The purpose of this note is to point out several obscure places in the results of Ahmed and Zeyada [J. Math. Anal. Appl. 274 (2002) 458-465]. In order to rectify and improve the results of Ahmed and Zeyada, we introduce the concepts of locally quasi-nonexpansive, biased quasi-nonexpansive and conditionally biased quasi-nonexpansive of a mapping w.r.t. a sequence in metric spaces. In the sequel, we establish some theorems on convergence of a sequence in complete metric spaces. As consequences of our main result, we obtain some results of Ghosh and Debnath [J. Math. Anal. Appl. 207 (1997) 96-103], Kirk [Ann. Univ. Mariae Curie-Sklodowska Sec. A LI.2, 15 (1997) 167-178] and Petryshyn and Williamson [J. Math. Anal. Appl. 43 (1973) 459-497]. Some applications of our main results to geometry of Banach spaces are also discussed.
Spatial and Temporal Variability of Soil Moisture  [PDF]
Vanita Pandey, Pankaj K. Pandey
International Journal of Geosciences (IJG) , 2010, DOI: 10.4236/ijg.2010.12012
Abstract: The characterization of temporal and spatial variability of soil moisture is highly relevant for understanding the many hydrological processes, to model the processes better and to apply them to conservation planning. Considerable variability in space and time coupled with inadequate and uneven distribution of irrigation water results in uneven yield in an area Spatial and temporal variability highly affect the heterogeneity of soil water, solute transport and leaching of chemicals to ground water. Spatial variability of soil moisture helps in mapping soil properties across the field and variability in irrigation requirement. While the temporal variability of water content and infiltration helps in irrigation management, the temporal correlation structure helps in forecasting next irrigation. Kriging is a geostatistical technique for interpolation that takes into account the spatial auto-correlation of a variable to produce the best linear unbiased estimate. The same has been used for data interpolation for the C. T. A. E. Udaipur India. These interpolated data were plotted against distance to show variability between the krigged value and observed value. The range of krigged soil moisture values was smaller than the observed one. The goal of this study was to map layer-wise soil moisture up to 60 cm depth which is useful for irrigation planning.

Hemant Kumar Singh, Brijendra Singh
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.57057
Abstract: In very short time today web has become an enormously important tool for communicating ideas, conducting business and entertainment. At the time of navigation, web users leave various records of their action. This vast amount of data can be a useful source of knowledge for predicting user behavior. A refined method is required to carry out this task. Web usages mining (WUM) is the tool designed to do this task. WUM system is used to extract the knowledge based on user behavior during the web navigation. The extracted knowledge can be used for predicting the users’ future request when user is browsing the web. In this paper we advanced the online recommender system by using a Longest Common Subsequence (LCS) classification algorithm to classify users’ navigation pattern. Classification using the proposed method can improve the accuracy of recommendation and also proposed an algorithm that uses LCS method to know the user behavior for improvement of design of a website.

Abstract: Malignant brain tumors consist of high-grade primary brain tumors such as malignant gliomas[1], and metastatic lesions to the brain from peripheral cancers such as lung, breast, renal, gastrointestinal tract, and melanoma[2,3]. Glioblastoma, the highest grade of malignant glioma, is the most common high-grade primary brain tumor in adults[4,5]. Overall, metastatic brain tumors are the most common brain tumors in adults, as 10% to 20% of patients with a malignant peripheral tumor develop brain metastases[2,3,6]. Even though malignant gliomas are generally treated with a combination of surgery, radiotherapy and systemic chemotherapy[7,8], and metastatic brain tumors with a combination of surgery and radiotherapy [9-11], the overall long-term prognosis of patients with these tumors, whether primary or metastatic, remains poor. Patient median survival times typically range between 3 and 16 months [12-16], and the percentage of patients alive at 5 years ranges between 3% and 10%[12,13,16,17]. In the treatment of both malignant gliomas and metastatic brain tumors, surgery and radiotherapy are more effective when used in combination[7-11,18-20]. In the treatment of malignant gliomas, there some minimal additional benefit of systemic chemotherapy[8,15,20-27]; and in the treatment of metastatic brain tumors, it remains unclear as to if there is any additional benefit of systemic chemotherapy[9,10,28-31].Systemic chemotherapy consists of small molecule chemotherapy drugs[8,32] that are drugs of molecular weights (MW) less than 1 kDa and diameters less than 1 to 2 nm. These small molecule chemotherapy drugs include traditional drugs that target the cell cycle, for example, DNA alkylating drugs, and newer investigational drugs that target cell surface receptors and associated pathways, for example, tyrosine kinase inhibitors[8,32]. The ineffectiveness of these chemotherapy drugs in treating malignant brain tumors has been attributed to the blood-brain barrier (BBB) being a sign
