Giant cell tumor of the flexor tendon sheath of the hand
Mazheruddin Ali Khan,Mohammed Mateen
Journal of Medical and Allied Sciences , 2012,
Abstract: Giant cell tumor of the tendon sheath (GCTTS) is a slowly progressing benign tumor arising from synovial cells of tendon sheaths. We report a case of GCTTS of the right ring finger in a forty year old female patient. Radiograph shows soft tissue globular swelling of the right ring finger with scalloping of the middle phalanx and irregular cortical outline with extrinsic soft tissue impression of the proximal phalanx due to pressure effect by the tumor. No evidence of soft tissue calcification is seen. Biopsy confirmed the diagnosis of Giant cell tumor of tendon sheath.

Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.37062
Abstract: Environmental degradation and unethical human intervention in the natural system has increased the concern for the betterment of healthy living. The deterioration of aquatic system is commonplace in the developing world. The present paper shows the trace elements (Ni, Zn, Fe, Pb, Cd, Co, Cu and Mn) concentrations in the drinking water of Aligarh city and their possible effect on the health of the inhabitants. The higher concen- tration of some elements in the drinking water and the poor health of inhabitants are found correlated. The statistical analysis of the data shows positive correlation between some elements. The principal component analysis of the data gives four factors with significance level of 42%, 29%, 15% and 12% respectively.

Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.79063
Abstract: A quantitative analytical data from the alluvial aquifers of Ganga-Sot Sub-Basin (GSSB) is subjected to multivariate statistical analysis in order to ascertain the groundwater quality characterization depending on the top soil/physiographic divisions. The matrix consists of ten variables of 34 groundwater samples collected from evenly spaced locations. The Hierarchical cluster analysis resulted in six clusters. Each cluster group is individually subjected to Principal component analysis (PCA). PCA of group A explains cumulative variance of 83%, and 95% of group of B, 82% of group C, 91% of group of D. Dissimilarity among the clusters is due to anthropogenic influence on the groundwater regime. The PCA is done for the groundwater quality data of the whole area and on the data of sub-divided area. The PCA of the whole area resulted in five components with cumulative variance of 69.19%. The area is sub divided on the basis of soil type/physiography and data falling in each sub-division is subjected to PCA. The PCA of clay loam soil/Ganga Mahwa low land resulted in five PCs explaining cumulative variance of 91%. The PCA of sandy soil/central upland data extracted four PCs with 80% of cumulative variance. The PCA of loam type of soil/Sot plain extracted three PCs explaining cumulative variance of 91.751%. The three physiographic units of the alluvium setting reflect distinct groundwater quality as manifested by the PCA. From this study it can be ascertained that PCA can be used for the characterization of groundwater quality information.

Huzoor H. Khan, Rifaqat Ali
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.29155
Abstract: In this paper we have generalized some results of Rahman [1] by considering the maximum of |f(z)| over a certain lemniscate instead of considering the maximum of|f(z)|, for |z|=r and obtain the analogous results for the entire function |f(z)|=Σpk(z) [q(z)]k-1 where q(z) is a polynomial of degree m and pk(z)is of degree m-1. Moreover, we have obtained some inequalities on the lover order, type and lower type in terms of polynomial coefficients.

Syed Ahmad Ali, Nazia Khan
Open Journal of Modern Hydrology (OJMH) , 2013, DOI: 10.4236/ojmh.2013.31004
Abstract:

Land and water resources are generally depleting due to rapid increase in population, urbanization and industrialization. The demand has increased tremendously for these resources; hence optimal utilization of them is essential for sustainable development. In the present study, detailed morphometric parameters of the Banas river basin has been carried out. The river Banas originating from the Khamnor hills of the Aravalli ranges (about 5 kms from Kumbalgarh) is one of the major rivers of the state which, in its entire course, flows through Rajasthan. It flows from Kumbalgarh towards the south upto Gogunda plateau and after cutting the Aravalli ranges at right angles, it flows through Nathdwara, Rajsamand and Railmagra. The total area of the Banas river basin is 702.55 km2. Detailed drainage map was prepared from SOI (Survey of India) toposheets (45h/5 and 45h/9) and was updated using IRS-P6, LISS-III (Precision geocoded) data of 7th May, 2010 using ARC GIS software. For detailed study, Shuttle Radar Topographic Mission (SRTM) was used for delineating watershed boundary using SAGA GIS software. GIS techniques has been used for assessing various morphometric characteristics of the drainage basin, as they provide a flexible environment and a powerful tool for the manipulation and analysis of spatial information particularly for the feature identification and extraction of information for better understanding. In the present study, the GIS analysis techniques were used to evaluate linear and areal morphometric parameters of the basin. Drainage patterns are mainly dendritic to sub-dendritic with fifth order drainage. Banas river basin possess high drainage density which is indicative of less permeable material, sparse vegetative cover and moderate to high relief.

Abstract:

Cauliflower is popular vegetable in Pakistan and it is severely attacked by Pieris brassicae (L). There are different cauliflower cultivars available in this area. The aim of this study was to determine the developmental response of Pieris brassicae on ten cauliflower cultivars. An experiment was conducted during 2012-13 at the Entomology section of the Agriculture Research Institute Tarnab Peshawar under laboratory conditions of 20°C ± 2°C, 50% ± 5% RH and 12:12h photoperiod. Pieris brassicae eggs were collected from a cauliflower field ARI Tarnab and the larvae placed after hatching on fresh leaves often cauliflower cultivars. The results showed that the larval development of P. brassicae was short (35 days), longer larval length (32.41 mm), larval mortality was low (6.6%) and pupal weight was high (0.50 g) on Clima cultivar. On the other hand, a longer larval developmental period (37 days), higher larval mortality (86.66%), shorter larval length (24.55 mm) and lower pupal weight (0.42 g) were recorded on cultivar AX-2034.

Communications and Network (CN) , 2014, DOI: 10.4236/cn.2014.63020
Abstract:

The trend in businesses is moving towards a single browser tool on portable devices to access cloud applications which would increase portability but at the same time would introduce security vulnerabilities. This resulted in the need for several layers of password authentications for cloud applications access. Single Sign-On (SSO) is a tool of access control of multiple software systems. This research explores the effects and implications of SSO solutions on cloud applications. We utilize a new framework of different attributes developed by acquiring IT experts’ opinions through extensive interviews to expand significant strategic parameters at the workplace. The framework was further tested using data collected from a sample of 400+ users in the UAE.
