Functional Magnetic Resonance Imaging (fMRI) is a technique for measuring brain activity that directly measures the blood flow in the brain. This is an important concept in medical field to detect the tumors. Tumors is an abnormal tissue which is grouped together to form into lumps. Tumor cells are grouped according to their growth of cells which has been graded by World Health Organisation. To detect the tumor we take an fMRI using various techniques. K means algorithm is introduced in this field to cluster together the different regions of the brain according to the interaction between various regions. These results are compared to original image to get the exact location of the brain tumor rather than the region surrounding the tumor cells.Keywords

Organizational Politics (OP) is a phenomenon that exists in society, and although people are seldom aware of it, it proclaims its ubiquitous presence. An insight into Organizational politics focuses on understanding the progress of Organizational politics. A simple OP Model illustrates how it springs from fundamental differences in perception and ideas and summits in the detrimental, illegitimate stage. Understanding the etiology of Organizational politics leads to a positive approach so that this powerful tactic can be leveraged for benefits. Organizational politics is all pervading. It is wiser to accept its ominous presence and guard oneself from its fangs. The factors indicative of politics are listed for this benefit. Finally, the impact of organizational politics on ethics and its major influence on society is highlighted.
The authors have developed a model to elucidate the etiology of Politics in an Organization. It stems from fundamental differences in perception, and ideas. It contributes a positive approach to the versatile tool of politics and advices on how to use it for benefits. Light is thrown on dangers of politics and to identify indicators of politics.

A simple, precise, rapid, selective and economical high performance thin layer chromatographic (HPTLC) method has been established for simultaneous analysis of Esomeprazole and Domperidone in capsule dosage forms. The chromatographic separation was performed on precoated silica gel 60 GF254 plates with Acetonitrile: Chloroform: Ammonia (12:7. 5:0. 5)(v/v/v)as a mobile phase. The drugs on the plate were scanned at 222 nm. The drugs were satisfactorily resolved with Rf 0. 31 for domperidone and 0. 48 for esomeprazole. The method was validated for linearity, accuracy, precision, and specificity. The calibration plot was linear between 200-1000 ng/spot for esomeprazole and domperidone. The limit of detection and quantification for esomeprazole was 85. 07 and 255. 21ng/spot and domperidone was 79. 07 and 237. 23 ng/spot. The percent recovery study was done by standard addition method found in the range of 98. 7% and 99. 1% respectively. The proposed HPTLC method is economic, sensitive, and less time consuming than other chromatographic procedures.
