Calcification in cerebral infarcts has been reported as an uncommon finding. CT hyperdensity in an infarct can also be due to hemorrhagic transformation and in MRI can be mimicked by cortical laminar necrosis seen as gyriform T1 hyper and T2 hypointensities. Susceptibility-weighted imaging (SWI) with phase image has been reported to differentiate calcification and hemorrhage. We report 2 cases of cerebral infarcts with a review of the literature. The first patient showed early gyriform calcification 10 days after the onset and showed partial resolution of the calcification on follow-up. The second patient showed plaque-like calcification within perisylvian infarct that was confirmed by SWI phase imaging.

Adsorption cooling system is an unconventional technique of refrigeration that uses heat to drive the system. This method is employed in remote areas wherever electricity is out of stock. The system refrigerant consists of 2 key elements refrigerant and sorbent material. During this work we tend to square measure mistreatment R134a and carbon simply accessible materials as refrigerant and adsorbent. R134a has low warming potential than alternative refrigerant. The cooling system conjointly consists of surface assimilation bed, condenser, and evaporator section. During this system we tend to square measure specializing in construction and performance analysis of thermal surface assimilation cooling system. In vapor compression cooling system refrigerants square measure compressed automatically instead of thermally. The system is in a position to bring down temperature of current water by quite 10oC that is encouraging compared to according literature., {"references":["Ahachad, M., Almers, A., Mimet, A., & Draoui, A.

The fundamental extent of this work is to configuration, create a vertical axis wind turbine for power generations applications in rural territories. Vertical Axis Wind Turbines were chosen to harness the energy from wind through the drag forces. It has a good starting torque and independent of the wind direction .In this project the fabrication of prototype of Savonius type Vertical Axis Wind Turbine (VAWT) is made using easily available materials like, plywood, sheet metal and bearing. This project is to design and fabricate a roof- mounted vertical axis wind turbine (VAWT) system. Natural concerns have been a significant issue in the engineering field. Wind turbines are the type of renewable energy source that will support the earth. Our venture result will create a product that will have the option to support nature and make society progressively self-manageable. This should be possible by making society progressively autonomous from utilizing fossil fuels. Our project is helping the succession of this idea and broadening the capability of turbine to reduce carbon footprints.The fundamental extent of this work is to configuration, create a vertical axis wind turbine for power generations applications in rural territories.

BACKGROUND Intensive care has developed over the past four decades in treating critically-ill patients. The cost of providing the intensive care services are also squaring up to astronomical levels. Risk scoring systems can be used to focus on quality of care provided to patients at ICU setup as they help in comparative audit that is comparison of actual and expected outcome for group of patients that can be used to compare different providers. The aim of the study is to1. Study the usefulness of ICU scoring systems (APACHE II, APACHE IV and SAPS III) developed in the west in an Indian ICU. 2. Calculate scores of patients admitted in our ICU as per various ICU scoring systems (APACHE II, APACHE IV and SAPS III). 3. To document the observed mortality among these patients. 4. To compare the observed mortality with mortality predicted by scoring systems (APACHE II, APACHE IV and SAPS III) to see if these ICU scoring systems developed in the West can predict mortality in an Indian ICU. MATERIALS AND METHODS The study was a prospective study over a period of one year (2011-2012) and patients are enrolled as per inclusion criteria. Sample size was set to be a minimum of 100. The physiological parameters, lab investigations, surgical status, chronic health condition including the demographic details as needed by scoring systems (APACHE II, APACHE IV, SAPS III) were recorded at the time of admission to ICU. Patients were followed up till the time of discharge and mortality among the study patients were documented. Statistical Analysis- Statistical analysis is done by using SPSS software. RESULTS This prospective study of 115 ICU patients evaluated the three ICU scoring systems namely, APACHE II, APACHE IV and SAPS III in ICU of a tertiary care corporate hospital shows there is a linear correlation between the scores and observed mortality with increasing scores, the observed mortality progressively increases. This suggests that the scoring systems are valid and can accurately predict mortality in Indian setting also the observed mortality in our cohort of patients is 40%. However, the predicted mortality as per APACHE II, APACHE IV, and SAPS III is only 33.51%, 33.5% and 28.53%. The risk of death for a given patient in our ICU with mean predicted mortality (SMR) is 1.2, 3.61 and 1.4 times that of the mortality predicted by scoring systems APACHE II, APACHE IV, and SAPS III, respectively. After obtaining the score for individual patients, the mortality predicted by the scoring systems should be multiplied by the above factor. Different ICU will have different SMR for any given scoring system depending on the standard of care of that particular ICU. So, individual intensive care units should establish their own SMR for any particular scoring system. SAPS III admission scoring in predicting mortality risk stands good as it is recorded within one hour of ICU admission and other scoring systems may be influenced by treatment. The limitations of the study are that the number of patients in the study is small to establish statistical significance. In addition, our study evaluated predominantly medical patients and may not be applicable to other types of ICU patients. CONCLUSION There is a linear correlation between the predicted scores and observed mortality with increasing scores, the observed mortality progressively increases. This suggests that the scoring systems are valid and can accurately predict mortality in Indian setting also.

Angiomyolipoma is a benign mesenchymal tumor occurring in about 0.3 % of the general population. Angiomyolipoma of the adrenal gland is a rare entity, and only 5 cases have been reported so far in English literature. Sarcoidosis is a systemic illness of unknown etiology characterized histologically by non-caseating epithelioid granulomas in the affected tissues. Angiomyolipoma of the adrenal occurring in sarcoidosis is an unusual association with no prior published reports. We describe a case of adrenal angiomyolipoma in a 60 year old female with sarcoidosis. (Sarcoidosis Vasc Diffuse Lung Dis 2017; 34: 81-84)
