MPIGA – Multipath Selection Using Improved Genetic Algorithm

The Wireless Multimedia Networks (WMNs) have developed due to the extensive applications of wireless devices and increasing availability of lower cost hardware. The WMNs are used to transmit the multimedia content like audio and video streaming and they can be deployed within a lower budget. These networks can also be used in real-time data applications that demand energy-efficient management and awareness of Quality of Service (QoS). The energy resources are limited in the wireless devices that lead to the significant threats on the QoS for WMNs. An energy-efficient routing technique is needed to handle the dynamic topology of WMN that includes a vital resource as energy. The energy-efficient routing method was proposed in this work for the purpose of data communication based on a cluster head selection from each cluster in addition to the multipath route selection to reduce the network overhead and energy consumption. The cluster heads for each cluster are selected based on Node Coverage & average residual energy parameters.In this work, the proposed energy efficient routing algorithm uses improved genetic algorithm (IGA)based on a cost function for dynamic selection of the best path. The proposed cost function uses link lifetime &average link delay parameters to estimate the link cost. The proposed algorithm’s performance compared with other previous routing methods based on extensive simulation analysis. The results showed that the proposed method achieves better performance over three other routing techniques

Os(VIII) catalysed oxidation of phenyl styryl ketone and substituted phenyl styryl ketones by periodate: Interactive free energy relationship

351-354Kinetics of Os(VIII) catalysed oxidation of phenyl styryl ketone and its substituted analogues by periodate has been investigated in acetic acid + dichloromethane + water medium in the temperature range 298-313 K. The rates are found to be enhanced by electron releasing substituents and retarded by electron withdrawing substituents both in benzaldehyde and acetophenone rings. However, the effect of substituents is more pronounced when they are present in benzaldehyde ring. The magnitude of PX(Y) value obtained from the slope of Hammett's plot for various substituents in benzaldehyde moiety decreases with the introduction of electron withdrawing groups in acetophenone moiety and vice versa. A linear plot is obtained between PX(v) and sy, (substituent constant for substituent in acetophenone moiety) with a slope of 0.36 ± 0.01. The plot of Py(x) (obtained from Hammett's plot for various substituents in acetophenone moiety) versus sx (substituent constant for substituent in benzaldehyde moiety) is also linear with a slope of 0.41 ± 0.01. The results have been analysed in terms of interactive free energy relationship

Intravitreal live adult Brugian filariasis

Human ocular infestation by live filarial worm is a rare occurrence and has been reported mostly form South-East Asia. It involves the eyelids, conjunctiva, cornea, anterior chamber and uvea. No case of intravitreal Brugian microfilaria / adult worm has been found by Medline search. Here we report a case of live intravitreal adult Brugian filaria, where the parasite was successfully removed by pars plana vitrectomy. Identification of the worm was done by light microscopy and confirmed by immuno chromatographic test

Rhabdomyolysis induced acute renal failure secondary to statins

Rhabdomyolysis is a syndrome characterized by muscle necrosis and the release of intracellular muscle contents into the systemic circulation. We report a patient with chronic kidney disease who had deterioration of renal function due to combination of risk factors like hypothyroidism and interaction of amlodipine and clopidogrel with statins

An Approach Toward the Synthesis of Β-hydroxy Sulfones on Water

Various β-hydroxyl sulfones are prepared by regioselective ring opening of epoxides with sodium salt of sulfinate on water. This is an efficient protocol which avoids hazardous and moisture sensitive catalysts. © 2009 Elsevier Ltd. All rights reserved

Climate change analysis in southern Telangana region, Andhra Pradesh using LARS-WG modelWeather-generating models are widely used for study ing the climate change over longer periods. LARS-WG model was evaluated for southern Telangana region (Hayathnagar, Yacharam and Rajendranagar). A 30- year base weather data (1980–2010) was used to gene rate the long-term weather series from 2011 to 2060. The results of t and F tests at probability of 5% for comparing means and standard deviations of monthly rainfall and air temperatures indicated that the observed and predicted series for the base period are within acceptable limits. The statistics of model effi ciency indicates that mean monthly rainfall and daily air temperature are close to the predicted series over the base period. The model efficiency was highest in the case of Rajendranagar (98.75%). The root mean square error and sum of square error varied from 0.4 to 1.3 mm and 615 to 1745 mm respectively. The model predicted the maximum increase in average annual rainfall of 5.16% in 2030 and 9.5% in 2060 for Yacharam compared to Hayathnagar and Rajendrana gar over the normal annual rainfall of the base period (1980–2010). However, the model predicted increase in average seasonal rainfall for Hayathnagar (6.2% in 2030 and 8.8% in 2060). In case of air temperature, the model predicted increase in maximum temperature in the range 1–1.53% and 2.5% for 2030 and 2060 re spectively, for these locations whereas minimum tem perature decreased in the range 3.7–10.2% and 6.3– 11.7% respectively, for 2030 and 2060. The perform ance of LARS-WG model was ranked high with maximum model efficiency in all selected mandals of Ranga Reddy district in southern Telangana. This model can be replicated in other mandals of southern Telangana as climate characteristics of the present mandals are similar to other districts in the region.Not Availabl
