The current IT cloud computing is playing a vital role in most of the areas such as Education, Research, Health care, etc. The cloud computing technology involving in sensor networks embedded system and IOT (Internet of Things). At present scenario, the sensors collected the information from the particular environment, where the sensors are fixed and transfer the collected information to cloud storage, here the challenge is the data transmission i.e. data that traverse from sensor to cloud environment are the big issue and maximum number of data loss is very high especially in dynamic routing environment. If data loss is identified in any routing path then automatically the information will transfer to alternate routing path. In this paper, we introduce a new algorithm for automatic routing path selection that can be integrated with cloud technology. This algorithm supports when data loss is found in the particular path of a network, then it selects an alternate route to transfer the data. The proposed model is comparatively more efficient than the prior methodologies. The implementation of the proposed work is done on NS3 simulator, and the performance metric is analyzed.

Polymer blends have been obtained in the form of dimensionally stable and free standing films and their properties were characterized by different techniques. FTIR analysis and Raman spectroscopic analysis cleared the hydrogen bonding intermolecular interaction between –CONH2 groups in Poly Acrylamide (PAM) and C-O-C and –CH2OH group in Poly Ethylene Oxide (PEO). From Differential Scanning Calorimeter (DSC) the study shows that crystallinity is increasing with PEO wt%. From polymer interaction parameter we also show that the polymer blend is miscible. Thermal stability of films is investigated by Thermo Gravimetric Analysis (TGA) and derivative Thermo Gravimetric Analysis (DrTG). From UV-Vis absorption spectra, absorption band edge, direct/ indirect band gap and optical activation energy have been calculated.

A capacity building program on drip irrigation (TNDRIP) was undertaken in certain regions of the Indian State of Tamil Nadu during 2009-2010. An assessment of the impact of the program in terms of effective use of drip irrigation and increased crop yields was made in 2011 by applying double difference method (a combination of both with and without and before and after approaches). The results had indicated that the drip capacity building program resulted in a yield increase of 2.5 t/ha for Banana 1, 1.9 t/ha for Banana 2, 3.3 t/ha for sugarcane and 0.3 t/ha for turmeric. The conventional method using the before and after situations had shown a yield increase of 4.3 t/ha for Banana 1, 12.1 t/ha for Banana 2, 40.6 t/ha for sugarcane and 2.6 t/ha for turmeric. The conventional approach is highly upward biased in estimating the impact of the drip capacity building program and thus the double difference method will be an appropriate method to evaluate the impact of the programs that involve both with and without as well as before and after situations.

在养禽业,益生菌作为饲料添加剂的使用,因其对宿主肠道健康和抗病力有深远的影响,已经获得了巨大的价值。益生菌添加剂可替代抗生素生长促进剂来预防家禽的坏死性肠炎。研究目的是对比益生菌(克洛生)和抗生素生长促进剂(AGP)对商业肉鸡生产性能的效果,试验地点选在易爆发坏死性肠炎的Kolkata加尔各答。试验分为2组,试验周期为40 d,试验1组7 500只肉鸡使用AGP[选用的是亚甲基双水杨酸杆菌肽(BMD)和维吉尼亚霉素];试验2组7 465只肉鸡使用克洛生。评估指标为体重、饲料转化率(FCR)、死亡率、欧洲效率因子(EEF)、肠道内容物梭菌含量及肉鸡肠道的健康状况。试验结果表明,与AGP组相比,益生菌(克洛生)组在肉鸡体重,饲料转化率和EEF方面显著提高,并显著降低了死亡率,在试验期间没有爆发坏死性肠炎。通过检测肉鸡肠道内梭菌数量表明,益生菌(克洛生)组比AGP组的肠道内梭菌降低了一个数量级,同时益生菌组肉鸡的肠道比AGP组的更健康。研究结果表明,益生菌(克洛生)在肉鸡生产性能方面具有优于促生长型抗生素的效果。

Hydrographical parameters and phytoplankton assemblages were determined along the Pondicherry, Parangipettai and Nagapattinam coastal waters, southeast coast of India. All the hydrographical parameters such as sea surface temperature, salinity, p H, total alkalinity, dissolved oxygen and nutrients like nitrate, nitrite, inorganic phosphate and reactive silicate, chlorophyll a and phytoplankton assemblages were studied for a period of five months(May, August, September 2010, March and November 2011). Over 121 species of phytoplankton represented by 93 species of diatoms, 16 species of dinoflagellates, 9 species of blue-green algae, 2 species of greens and 1 species of silicoflagellate were recorded. High phytoplankton species diversity was found in March 2011 when salinity and nitrate concentrations were low and reactive silicate and inorganic phosphates were moderate. Species diversity was low during May 2010 when increased sea surface temperature, salinity and low nutrients availability were observed. Coscinodiscus centralis, Diatoma vulgaris and Proboscia alata were dominant, especially Coscinodiscus sp. distributed in all stations whereas Skeletonema costatum, Odontella sinensis and Ditylum brightwellii were abundant in August and September 2010. From principal component analysis and multiple regression analysis, it is evident that variables like sea surface temperature and dissolved oxygen are the most important factors influencing the seasonal pattern of phytoplankton population.

Pure and Molybdenum (Mo) doped Potassium Titanyl Phosphate (KTP) inorganic crystals were grown by high temperature solution growth (HTSG) from poly phosphate (K6P4O13) flux using different KTP/Flux ratios. The pure and doped KTP crystals of size 20x13x5 mm3 and 7x5x2.5 mm3 respectively were grown successfully by spontaneous nucleation. The grown crystals were characterized by XRD, UV, FTIR and Hardness studies. Micro hardness studies show that the pure crystals are harder than the Mo doped crystals.

AIM: To evaluate whether there is a threshold sensitization level beyond which benefits of chronic steroid maintenance(CSM) emerge. METHODS: Using Organ Procurement and Transplant Network/United Network of Organ Sharing database, we compared the adjusted graft and patient survivals for CSM vs early steroid withdrawal(ESW) among patients who underwent deceased-donor kidney(DDK) transplantation from 2000 to 2008 who were stratified by peak-panel reactive antibody(peak-PRA) titers(0%-30%, 31%-60% and > 60%). All patients received perioperative induction therapy and maintenance immunosuppression based on calcineurin inhibitor(CNI) and mycophenolate mofetil(MMF).RESULTS: The study included 42851 patients. In the 0%-30% peak-PRA class, adjusted over-all graft-failure(HR 1.11, 95%CI: 1.03-1.20, P = 0.009) and patientdeath(HR 1.29, 95%CI: 1.16-1.43, P 60% peak-PRA class, adjusted overall graft-failure(HR 0.90, 95%CI: 0.76-1.08, P = 0.25) and patientdeath(HR 0.92, 95%CI: 0.71-1.17, P = 0.47) risks were similar and death-censored graft-failure risk lower(HR 0.84, 95%CI: 0.71-0.99, P = 0.04) for CSM(n = 4966)vs ESW(n = 923).CONCLUSION: In DDK transplant recipients who underwent perioperative induction and CNI/MMF maintenance, CSM appears to be associated with increased risk for death with functioning graft in minimally-sensitized patients and improved death-censored graft survival in highly-sensitized patients.
