Diagnosis of hypertensive encephalopathy largely relies on exclusion of other neurological emergencies. We review the extensive causes of PRES and its imaging characteristics. Management strategies have not changed substantially in the past decade, though newer calcium channel blockers simplify the approach to blood pressure reduction. While this alone may be sufficient for treatment of hypertensive encephalopathy in most cases, management of PRES also depends on modification of other precipitating factors. Hypertensive encephalopathy and PRES are overlapping disorders for which intensive blood pressure lowering is critical. Further research is indicated to both in diagnosis and additional management strategies for these critical conditions.

Azoles such as benzotriazole and benzimidazole are used as corrosion inhibitors, particularly for copper. The purpose of this work is to further illuminate the bonding and film growth for benzimidazole-like structures. The interaction of imidazole, benzimidazole, 2-methylbenz-imidazole and benzotriazole with copper surfaces is studied with a quartz crystal oscillator microbalance and with X-ray photoelectron spectroscopy. The copper surface is etched by imidazole in water and in CH30H and by benzimidazole in CH30H. A very thin film, probably a monolayer or less, is left behind after etching. Thicker films, 500 to 1000% are formed by benzimidazole in water and by 2-methylbenzimidazole in both water and CH30H. Mechanisms of bonding and film formation for the thin and the thick films are discussed.

The study of this work is to highlight the key metrics of various topologies in terms of output power, Fill Factor (FF), Mismatch Losses (ML) and efficiency. The idea behind this work is to analyze and obtain the performance of different topologies under various shading patterns. The major problem which comes across the path of Photovoltaic (PV) system performance is partial shading. The solution to this problem is to reconfigure the panels to achieve better results under shading conditions. For this, different configurations such as Series Parallel (SP), Total Cross Tied (TCT), Physical Relocation of Module with Fixed Electrical Connections (PRM-FEC), SuDoKu and Magic Square (MS) has been discussed, analyzed and compared using MATLAB/SIMULINK. Simulation approach is used to describe the working and evaluation of all configurations. By the results obtained, it is clearly visible that MS method have achieved largest output power of 2877 W, highest efficieny of 10.24 %, FF is 0.481 and lowest ML of 772 W among all the configurations under Long Narrow (LnN) pattern.
