Ramaswami, N.,Chaudhary, L.C.,Agarwal, N.,Kamra, D.N. Asian Australasian Association of Animal Productio 2005 Animal Bioscience Vol.18 No.8

To study the effect of feeding lactic acid producing bacteria on the performance of cattle calves, twenty four, day old male crossbred cattle calves (Bos indicus${\times}$Bos taurus), were distributed into two groups of 12 animals each. The animals were fed on calf starter containing wheat bran and green berseem ad libitum and milk as per requirement upto 8 weeks of age. The diet of calves of Group 2 was supplemented with 500 ml culture of Lactobacillus acidophilus-15. Total duration of the experiment was 31 weeks. There was no significant difference in intake and digestibility of dry matter (DM), organic matter (OM), neutral detergent fibre (NDF), acid detergent fibre (ADF) and crude protein (CP) between the groups. The rumen pH, protozoa numbers, concentration of volatile fatty acids (VFA), ammonia nitrogen ($NH_3-N$), trichloroacetic acid precipitable nitrogen (TCA-ppt N) and activity of microbial enzymes (carboxymethylcellulase, xylanase, amylase and protease) were not affected due to probiotic supplementation. Average live weight gain of the calves was improved (about 10%) and feed:gain ratio was reduced (about 5%) in the animals given Lactobacillus culture. The data indicated that crossbred calves could be reared on a diet devoid of cereal grain and addition of Lactobacillus culture in the diet resulted in an added advantage in growth performance of the animals.

Risk and resilience factors for substance use among street adolescents: Assessment and development of an integrative model

Ramaswamy Dhanasekara Pandian,Govindappa Lakshmana 한국사회복지학회 2017 Asian Social Work and Policy Review Vol.11 No.3

In this study, risk and protective factors for substance use were explored to develop an intervention program and test its efficacy among male street-based adolescents. Twenty expert interviews and key informant interviews were conducted. In addition, 30 street adolescents (15 substance-users and 15 non-users) participated in four focus group discussions for needs assessment, wherein risk and protective factors were discussed. Based on the identified needs, an intervention package was developed and validated by experts. The package was implemented in a natural environment of 50 street adolescents. After the intervention, about 60% of the respondents quit or cut down on their substance use substantially, and approximately 40% of the respondents agreed to reunite with their respective families, while 20% did not change their substance use habits. The results showed that if several protective factors were present, there was a lower risk of substance use. Many factors contribute to substance use and protective factors need to be strengthened in order to make interventions effective.

Pod and Seed Traits in Candidate Plus Trees of Pongamia pinnata (L.) Pierre from Southern Peninsular India in Relation to Provenance Variation and Genetic Variability

Hosalli Ramaswamy Pavithra,Balakrishna Gowda,Kuthi Thammaiah Prasanna,Manchanahally Byrappa Shivanna 한국작물학회 2013 Journal of crop science and biotechnology Vol.16 No.2

Provenance variation and genetic variability in pod and seed traits were carried out with 232 candidate plus trees of Pongamia pinnata collected from selected agro-ecological zones of southern peninsular India during February-March 2008 to 2010. Significant variation (P < 0.01) for pod and seed traits across zones and provenances within zones was recorded. The southern dry and transition zone of Karnataka showed the highest mean value for all the pod and seed traits. A significant negative (P < 0.05) correlation and positive correlation was recorded for latitude with 100-seed weight and seed germination, respectively. Altitude positively correlated with 100-pod weight and negatively correlated with oil content. Phenotypic co-efficient of variation was higher than the genotypic co-efficient of variation indicating the influence of environment. Central dry zone and eastern dry zone of Karnataka showed high heritability and genetic advance for 100-pod weight, 100-seed weight, and seed germination. Positive significant (P < 0.05) genotypic correlation of co-efficient was recorded between seed thickness and oil content (0.211). Germination percentage showed significant positive correlation with seed weight and oil content. Path analysis revealed that seed thickness contributed directly to oil content (0.272). Based on D2 analysis, pongamia accessions could be grouped into seven clusters. Maximum diverse Clusters I and VII were identified based on inter-cluster distance (40.19). Thus on the basis of the present findings, it might be suggested that accessions from these clusters could be most suitably used for hybridization and in situ germplasm conservation

Preparation of barium sulphate nanocrystals in ethanol - water mixed solvents

V. Ramaswamy,R. M. Vimalathithan,V. Ponnusamy 한양대학교 세라믹연구소 2011 Journal of Ceramic Processing Research Vol.12 No.2

Precipitation of nanoparticles is an important production procedure in industry to receive nano materials that are widely used in many fields. The product properties are strongly dependent on the properties of the particles i.e., average size, size distribution and morphology. The specific properties and applications of barium sulphate nanoparticles have attracted intensive investigation. There are numerous tedious techniques for synthesis of nano particles. However, in this study, barium sulphate nanoparticles were successfully synthesized using an ordinary chemical precipitation technique. Barium sulphate nanoparticles were synthesized using barium chloride and ammonium sulphate as reagents by an ordinary precipitation process in the presence of ethanol/water mixed solvents. Different compositions of ethanol/water mixed solvents were taken for this synthesis process. Precipitated samples were characterized using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and X-ray diffraction (XRD) techniques. The size and morphology were determined using XRD and SEM techniques respectively. From the XRD results, the sizes of the particles ranged from 85nm to 54nm. The particle sizes are decreased when the vol.% of ethanol is increased.

India’s Logistics Exchange Memorandum of Agreement (LEMOA): A dysphoria in disguise

Mahesh Ramaswamy,Asha Shivaswamy 한국외국어대학교 국제지역연구센터 2018 International Area Studies Review Vol.21 No.3

The adage ‘big stick policy’ (in the sense of ‘speak softly but carry a big stick’, advocated by Theodore Roosevelt, 26th President of the USA), though buried by political scientists, is fast returning to the arena of international politics, with savvy moves being made by the new government of India. With the aim of neutralizing the influence and power of China in Asia, India is making swift changes under the govern of Narendra Modi to harness anti-Chinese waves. To substantiate this, there has been a flip-flop in traditional foreign policy. Globalization is facilitating a newfound synergy for India. The USA, which swayed under Chinese tempest during the last decade, is reasserting its ‘numero uno’ position now that its economy is in recovery mode. Naturally, India is the USA’s ally in alien Asia; however, India comprehends the USA’s perception of it’s growth story.

A Randomised Clinical Trial Pilot: Effect of Internal Biliary Stent on Biliary Complications in Living Related Liver Transplantation

( Vasudevan Ramaswamy ),( Manoj Gupta ),( Aneela T ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

Aims: Wether internal biliary stenting can alter the occurrence of biliary complications and overall outcome in living donor liver transplantation (LDLT) is not clear. There are no randomised studies to suggest if stenting helps, in the current literature. Methods: Aim Describe our technique of placing the stent Assess impact of stent on biliary complications and overall outcome Methods: 30 consecutive recipients were randomized to biliary anastomosis with and without intraductal stent. Stent: 6F infant feeding tube, cut to15 cm, extending across anastomosis into duodenum & was placed before securing the corner knot on the posterior wall. Biliary anastomosis was performed using interrupted PDS 6-0 sutures. Stent was passed into the smaller duct when two ducts were anastomosed. Sten removal: endoscopically at six weeks, earlier in case of problems. Exclusion criteria: ABO incompatible transplant, retransplantation and hepaticojejunostomy Results: Demographic features & characteristics were similar in both groups. Right lobe without MHV was the commonest graft used, 2 patients in group B had right posterior sectoral graft. 60% of patients in both groups had bile duct diameter ≤ 4mm. Hospital & ICU stay was not statistically different between the groups (P=0.89). Incidence of biliary complications: 26.6% (8/30), 10% bile leak, 16.6% stricture. Group A: No Stent (%) Group B: Stent (%) Two duct to duct anastomosis 40 26.6 Biliary Complications 33.3 20 (p=0.49) Bile leak 6.6 13.3 Stricture 13.3 20 3 & 12month survival 93 100 18month survival 93 93 All patients with bile leaks in group A developed late strictures. There were no complications attributable to the stent or stent removal process. Conclusions: Use of internal biliary stent is safe and potentially beneficial in LDLT, quantum of which needs to be clarified by the full study.

Finite element analysis of shear critical prestressed SFRC beams

Ananth Ramaswamy,Job Thomas 한국계산역학회 2006 Computers and Concrete, An International Journal Vol.3 No.1

This study reports the details of the finite element analysis of eleven shear critical partially prestressed concrete T-beams having steel fibers over partial or full depth. Prestressed concrete T-beams having a shear span to depth ratio of 2.65 and 1.59 and failing in the shear have been analyzed using 'ANSYS', The 'ANSYS' model accounts for the nonlinear phenomenon, such as, bond-slip of longitudinal reinforcements, post-cracking tensile stiffness of the concrete, stress transfer across the cracked blocks of the concrete and load sustenance through the bridging of steel fibers at crack interface. The concrete is modeled using 'SOLID65?eight-node brick element, which is capable of simulating the cracking and crushing behavior of brittle materials. The reinforcements such as deformed bars, prestressing wires and steel fibers have been modeled discretely using 'LINK8'-3D spar element. The slip between the reinforcement (rebar, fibers) and the concrete has been modeled using a 'COMBIN39" non-linear spring element connecting the nodes of the "LINK8' element representing the reinforcement and nodes of the 'SOLID65' elements representing the concrete. The "ANSYS' model correctly predicted the diagonal tension failure and shear compression failure of prestressed concrete beams observed in the experiment. The capability of the model to capture the critical crack regions, loads and deflections for various types of shear failures in prestressed concrete beam has been illustrated.
