Shape changes in Au/Ag bimetallic nanoparticles have been studied under continuous oil bath heating at 150 ^oC in ethylene glycol (EG) on the basis of TEM, TEM-EDS, and UV-Vis spectral data of products. When a mixture of polygonal Au and spherical Ag particles was heated for 10-60 min, they melted each other and became spherical Au/Ag alloys with an average diameter of 207\pm 35 nm. When polygonal Au seeds were added to AgNO_3/EG/PVP solution heated at 150 ^oC for 10-60 min, a significant shape changes in products were observed. After continuous heating for 30 min, Au@Ag core shell particles attached to Ag rich Ag/Au alloy nanowires and after 60 min heating they are turned to excentered Au@Ag/Au nanoparticles with an average diameter of 414\pm92nm. The new type excentered Au@Ag/Au nanoparticles consist of a small spherical Au component and Ag rich Ag/Au alloy component.

Though cow is a sacred animal in India, is dying an unnatural death in India. The quest is who is responsible for the unnatural death of cow progeny in India, dairying practices, veterinary services, vaccination with substandard vaccines, veterinary administration involved in vaccine and drug quality monitoring or anyone else. Diseases including foot and mouth disease (FMD), hemorrhagic septicemia (HS), black leg/ black quarter (BQ), anthrax and John's disease (JD) are the common killers prevailing since ages in India despite the availability of vaccines and other measures to control and stamp out these.

Axone, a fermented soybean food of Nagaland, is a common side dish in North-East India and neighbouring countries. In the study 191 samples of axone collected from 7 tribes (44 Angami, 12 Ao, 36 Chakesang, 3 kuki, 62 Lotha, 2 Pochury and 32 Sema) were analyzed. The pH of matured axone (5.7 to 8.62) was significantly (p<0.001) higher than fresh (4.56 to 7.54) and dried axone (5.58 to 8.54). The pH of Sema axone (8.02) was significantly (p, 0.001) higher than average pH of axone of other tribes. Total aerobic mesophilic plate count (TAMPC) of axone ranged between 6.44 Log10 cfu/g and 12.98 Log10 cfu/g. The aerobic endospore count (AEC) in axone (5.6Log10 to 10.55 Log10 cfu/ g) had strong correlation with TAMPC (r, 0.41) and was the major constituent of it. Of the twelve species of Bacillus identified in axone five most common were B. coagulans (55.5%), B. pantothenticus (12.4%), B. subtilis (11.5%), B. stearothermophilus (8.4%) and B. lentus (6.3%). About one third (31.4%) axone samples were positive for coliforms... more

In the study except a strain of Dermatophilus congolensis isolated from a dog blood suffering from pyrexia, all bacterial isolates from diseased animals were resistant to discs containing 2 microL sage oil. The only sensitive strain of D. congolensis also showed narrow zone (8 mm) of growth inhibition while the sensitive reference strain of E. coli-382 had 10-12 mm zone of growth inhibition around SEO discs. The MIC for the reference E. coli strain was 0.64 microL/ ml while for D. congolensis strain it was 1.28 µl/ ml with all three methods (agar dilution, broth dilution and agar well methods) of MIC determination. Sage oil MIC for four Streptococcus species strains was 2.56 µl to 5.12 microL/ ml while for three strains of Pasteurella canis and four strains of Plesiomonas shigelloides was 5.12microL / ml. For screening purpose, disc diffusion assay for antimicrobial activity appeared useful tool. The study revealed that MIC of sage oil could be determined using any of the three (broth dilution, agar dilution or agar well) methods without any significant variation among results... more

Integrated farming is popular in India but little is understood about circulation of multi-host pathogens under the emerging farming systems (IFS). Circulation of Edwardsiella a pathogen of public health importance has been studied in IFS. Gill swabs of fish (8), pond water (8), rectal swabs of pig (36) and cloacal swabs of duck (32) from an IFS and 24 samples each of rectal swabs of pigs and cloacal swabs of ducks from the down colony (300 m on down side from the farm) were analyzed for the presence of edwardsiellae and heterogeneity among the isolates. A total of 24 E. tarda and 6 E. hoshinae were isolated. No E. hoshinae was isolated from the IFS. We isolated both E. tarda and E. hoshinae from ducks but no E. tarda in down colony pigs. Though 55% E. tarda from the IFS were multi-drug-resistant (MDR) type, no MDR strain was detected in the down colony. Plasmid(s) were detected in E. tarda but not in E. hoshinae isolates. The study concluded that E. tarda may be detected in all components of the IFS but E. tarda from different sources may not be of similar type... more

Objective: The study was conducted with single objective, to understand effect of foot and mouth disease (FMD) on secondary sex ratio (SSR) in dairy animals including cattle (Bos indicus, Tharparkar; Bos indicus + Bos taurus, Vrindavani) and Murra buffalo (Bubalus bubalis) maintained at Indian Veterinary Research Institute, Izatnagar. Design: Retrospective data for six years of IVRI, Izatnagar Dairy farm having an average population of about 1000 livestock was analyzed for sex-specific calf birth, abortions, still births and mortality were assessed with reference to the FMD outbreak years and non-FMD outbreak years. In the study period, two FMD outbreaks were recorded one in 2010 June (due to FMD virus type"O") and other in January 2016 (due to FMD virus type "A"). Results: In years of FMD outbreak (2010-11 and year 2015-16), there were no biases of the disease towards sex and breed of the affected animals. However, FMD lesions were more apparent in calves and young stocks of Vrindavani strain. In years of FMD outbreaks on the farm male calf births were significantly more than female calf births (in 2010-11, male: female:: 1... more

Mobile cloud computing platforms represent a more secure way for provisioning applications and online services to users over mobile networks. Mobile cloud provisioning takes advantage of the inherent benefits of cloud computing for monitoring, security detection and malware prevention capabilities to protect its mobile users. Security and privacy preservation in is the main expectation of the cloud users in Mobile based cloud servicing. In this project, cloud based secure mobile health care model with feedback decision support is proposed. This mainly aims to improve the quality of the health care with reduced complexity and no compromise in security. This paper also mentions the difficulty imposed on client privacy and monitoring the service provider. To protect the client privacy, Boneh-Franklin Identity based encryption is proposed to reduce the decryption complexity due to the use of IBE (Identity based encryption) technique. To protect mobile Health (m-Health) service providers programs, the branching tree is expanded by random permutation and the decision thresholds used at the decision branching nodes are also randomized... more

Ag-Au alloy nanoparticles with tunable shape and composition were prepared by a replacement reaction between Ag nanoparticles and chloroauric acid at one hundred and fifty degree celsius temperature under oilbath heating. The replacement reaction between silver nanostructures and chloroauric acid solution has recently been demonstrated as a versatile method for generating Au-Ag alloy nanostructures via galvanic reaction. Here we describe the results of a systematic study detailing the morphological, structural, compositional involved in such a heterogeneous reaction on the nanoscale. This method leverages upon the rapid interdiffusion of Ag and Au atoms in the reduced dimension of a nanoparticle in the replacement reaction. This method of preparation has several notable advantages: (1) independent tuning of the shape, size and composition of alloy nanoparticles; (2) production of alloy nanoparticles in high concentrations; (3) general utility in the synthesis of alloy nanoparticles that cannot be obtained by the co-reduction method.

Axone (Akhuni), a homemade Nagamese fermented soybean product, is known for its umami flavor and taste and eaten as a delicacy in North Eastern India. Incorporation of Axone (1% w/w) in commercial poultry feed significantly improved growth rate (weight gain) both in piglets (p, 0.01) and grower pigs (p, 0.039). However, in grower pigs, growth rate was hampered in first week of experiment (p, 0.045) probably due to smelliness of Axone, feed was not consumed in required quantity by pigs. The study revealed that addition of Axone in pig feed might be significantly effective to get better production and can boost the profit of pig farmers.
