Vietnam - India defense cooperation since 2007: reality and prospect

Author: 
Nguyen Huu Quyet
Abstract: 

This paper examines Vietnam-India defense cooperation since the two countries elevated their bilateral relations to the strategic partnership in 2007. The paper gives an insight into the reality of the bilateral defense partnership highlighted by high-level exchange visits, an annual security dialogue, naval port visits, military training and maritime capacity building as well as assistance in maintaining military equipment, and arms transfer. The new height of Vietnam-India partnership is arguably an indispensable result not only due to the long-standing relations of amity and the elevation of the strategic partnership, but also, more importantly, due to both countries’ increasingly converging strategic interests in the past decade. The new achievements in Vietnam-India defense and security cooperation will lay a sound ground for both countries to forge ahead comprehensive and authentic cooperation in the coming years to bid for a greater role and position in the region and in the context of a rising and increasingly assertive China, particularly in territorial claims. This study is conducted employing qualitative method with data drawn from published party documents, policy papers, international journal articles, and particularly domestic and international media outlets that covered debates on foreign policy related issues and reviews of the Ministry of Defense and the Ministry of Foreign Affairs.

Abstract: 

Introduction: The endothelial dysfunction is one of the most difficult forms of vascular malformation. The dominant ferment, that provides the synthesis NO in the blood-making stream, is the endothelial NO-synthase, that is produced on the endothelium and plays an important role in the basic level NO support (Erdei et al., 2014; Cwynar et al., 2015). It is proved that the reduction of the activity еNOS leads to the decrement NO production and is one of the key elements of pathogenesis coronary heart disease (CHD) (Zaremba, 2012).
The aim of the research: to estimate the influence of the additional usage of L-arginine hydrochloride on the factors of vasodilation and the clinical data, complicated with cardiac decompensation with impaired and reserved ejection fraction of the left ventricle that patients with stable CHD have.
Materials and methods: To achieve the aim of the research the full medical observation with 40 CHD patients was held (28 men and 12 women, the average age is 68,80±0,90 years), who were in the heart disease department for the patients with rhythm disturbance Vinnytsya regional cardiovasculare pathology centre (Ukraine).
Results: After the comparing the levels of the vasodilatation factors of the healthy people (the control group) with the information that the patients with the stable CHD, complicated with HF with impaired and reserved LV EF, the certain difference between the markers of the levels еNOS, nitrites and nitrates in the blood serum (p<0.01), that deposes the increasing of the endothelial dysfunction. Similar results were obtained in patients 2 groups. , the patients with the decreasing LV EF and the progressing HF had the certain decreasing of the level еNOS, nitrites and the nitrates in the blood serum, that deposes the negative difficulties of the endothelial function. The analogical information got after the standard complex therapy HF during 10 days with the additional usage L-arginine hydrochloride at a dose 100 ml 4,2 % intravenous, the patients of the first group have the following level еNOS 664,80±85,68 pg/ml, the patients of the second group – 837,81±49,98 pg/ml (p<0.01), that deposes the positive effect of the additional usage of L-arginine hydrochloride. After the complex standard treatment during 10 days tolerance to the physical work in the patients І and ІІ groups increased. The results of the research proves that the patients with the stable CHD, complicated with HF with decreased and reserved LV EF after the usage of “Tivortin” 100 ml 4,2 % intravenous during 10 days influenced the increasemnet of FC HF.
Conclusions: After the comparing the levels of the vasodilatation factors of the healthy people with the information that the patients with the stable CHD, complicated with cardiac decompensation with impaired and reserved fracture of the left ventricle, the certain difference between the markers of the levels еNOS, nitrites and nitrates in the blood serum, that deposes the increasing of the endothelial dysfunction. After the treatment heart failure during 10 days with the additional usage L-arginine hydrochloride at a dose of 100 ml 4,2 % intravenous, the level of the vasodilatation increased, particucar the endothelial NO-synthase not only in the patients with stable CHD, with impaired and reserved fracture of the left ventricle. The results of the research proves that the increasing levels of vasodilators in the blood serum influences the decreasing of the clinical symptoms heart failure, that deposes the effectiveness of the following therapy.

Behavior of 3d RC frames with varying proportion of opening in masonry infills subjected to dynamic loading

Author: 
Jayaramappa, N. and Arunkumar Sagar
Abstract: 

Masonry Infills, which generally have high stiffness and strength, play a crucial role in reinforced concrete frame buildings during earthquakes but these are normally considered as non-structural elements and their stiffness contributions are generally ignored in practice, such an approach can lead to an unsafe design. The Masonry infill (MI) though constructed as secondary elements behaves as a constituent part of the structural system and determines the overall behaviour of the structure especially when it is subjected to seismic loads. The proportions of opening in MI play a major role in the seismic analysis of RC frames. In this seismic analysis, 3D RC frames by varying the number of store’s, proportions of opening in MI and soft storey is considered. The MI is represented by equivalent diagonal strut and the proposed openings are considered with aspect ratio of the opening to that of the infill. Finite Element Analysis is adopted in modeling, equivalent static and response spectrum analyses are used. The results such as natural time period, mode shapes, base shear for static and dynamic loading, storey displacement and storey drift are presented.

Author: 
Linda Appiah Boamah, Ernest Kusi and Ampaw Kofi Nyarko
Abstract: 

Population growth, urbanization and economic development are some factors contributing to an increase in waste quantities and diversification. Characterization and quantification of waste enhances efficient comparisons of different waste management systems .This study sought to investigate the quantity and characterization of land filled waste. Questionnaires, interviews, site visits and hand/manual sorting were done to obtain primary sources of information. This was substantiated with secondary data from books, journals and internet. Information for waste characterization study was obtained using recording sheet developed by Flint off. Three landfill sites (Kpone landfill, Abokobi dump and Nkanfoa dump sites) were selected. Twelve 240 L waste bins were filled with the waste from the landfill. A bin was weighed and its contents were sorted into organic, paper, metals, glass, textiles, plastics and rubber, residues and inert matter. The mass of the sorted fractions were measured with a mass balance and recorded. Average masses were calculated after the process was repeated for the other eleven bins. Organic component which was the highest waste stream in landfilled wastes accounted for about 51.90%, whiles residues had the lowest component (3.22%). Waste sorting and recycling would reduce the amount of waste that end up at the landfill sites.

Abstract: 

The pri Pesticides have become integrated into transport and degradation processes that characterize soil ecosystems. Although, pesticides are anticipated to protect crops, they may affect non-target organisms and pollute soil environment which might result in alteration in the equilibrium of soil processes for shorter or longer periods. Eleven fungal species like Aspergillus flavus, A.niger, A.oryzae, Curvularia lunata, Fusarium oxysporum, F.solani, Penicillium aurentiogriseum, P.chrysogenum, P.frequentans, Rhizopus stolonifer and Trichoderma harzianum were selected for the study. Three commercial insecticides i.e; Dimethoate, Profenofos and Chlorpyriphos were used to study their effects on soil fungi. The study was conducted to determine the effects of insecticides application on soil fungal populations, at different application rates ranging from ½litre, 1litre and with the control soil samples having no insecticide injection. A total of 282 colonies of 11 species were isolated from the control plates examined in 3 different crops (Rice, Black-Gram and Ground-Nut) of Narasannapeta Mandal, in Srikakulam District. 230 and 158 colonies were isolated from the soils treated with ½ and 1 Lt Dimethoate. From the use of Dimethoate none of the species were extinct. 215 and 144 colonies were isolated from soils treated with ½ and 1 Lt Profenofos, and finally a total of 194 and 125 colonies were obtained from soils treated with ½ and 1 Lt of Chlorpyriphos, thus confirming Chlorpyriphos as the more destructive among the insecticides used. Application of Profenofos and Chlorpyriphos yielded similar results leading to the extinction of F.oxysporum, F.solani and T.harzianum. The results revealed that insecticide applications caused reduction in microbial population present in the soils when compared with the control.

Computational analysis of catalyst light-off temperature in exhaust system of an IC engine

Author: 
Vijaygouda M. Hiregoudar, Srivatsa S and Praveenkumar B. S.
Abstract: 

Catalytic converter of an engine becomes operational at a temperature of around 200 to 225˚C. During cold conditions engine components take more time to warm up, similarly the catalytic converter also takes more than usual time to reach light-off temperature, which means exhaust gases will escape untreated. In these situations the placement of the catalytic converter plays an important role, i.e. if it is placed too near to head of exhaust, time required to reach light-off temperature will be less and if it is too far, time taken will be large. In our work we have analyzed the exhaust gas flow and studied the variation of temperature with time and optimize the location of catalytic converter. We have used Pro-E Wild fire-5 for geometry modeling and ANSYS FLUENT and CFD for analysis purpose.

Abstract: 

Diabetes Mellitus is one of the most challenging chronic illnesses these days. Poor knowledge and wrong perception of this disease and its management often results in poor control, severe complications and increased incidence of morbidity and mortality among its sufferers. This descriptive study was to assess knowledge and perception of diabetes mellitus and its management among diabetic patients in Federal Medical Centre, Yenagoa, Bayelsa State. Purposive sampling technique was used to select 150 patients using the rule of thumb and a structured questionnaire was used for data collection. A copy of the questionnaire was presented to clinicians, research experts and a statistician for review and necessary inputs and was pre -tested on 10 patients at Niger Delta University Teaching Hospital Okolobiri yielding a Pearson correlation coefficient of 0.89. Data obtained was presented in tables, figures; pie and bar charts and formulated hypotheses tested using Chi-square (X2). Ethical approval was sought and obtained and all respondent were duly assured of confidentiality during the period of study. Findings revealed high knowledge as well as positive perception of diabetes mellitus and its management among participants. Cost of treatment, lack of awareness to seek care, educational status, and cultural beliefs were identified as factors influencing participants’ perception of diabetes and its management. A significant relationship was observed between perception of respondents and their knowledge of diabetes mellitus and its management. Nurses were advised to ensure that diabetic patients have knowledge and positive perception of the disease condition and its management through continuous patient education.

Author: 
Saraswathi Gopal, K., Naveen Kumar.B and HarshaVardhan, B.G.
Abstract: 

Introduction: Scientific Advancements come as a boon to mankind. Mishaps bring doom. In mass disasters such as aircraft crashes or bomb blasts where there is gross mutilation of bodies, there has always been a search for the ideal clue which can help in individual identification. There is a demand that the remains be high temperature resistant and can directly point out to the individual without too much hassles. This retrospective study investigates one such valuable evidence- Implants
Aim: To retrospectively correlate Radiographic images of implants with their shapes and designs in catalogues, and Identify Implant Brand with which Person identification can be deciphered from the implant database
Method: 40 implant images will be correlated on basis of implant shapes, size and designs with the implant catalogue/ Library tool, and the implant brand will be recognized.
Result: Out of 40 implant images assessed, a positive correlation was seen in 33 cases. The study found that dental implants could be radio graphically differentiated by company type.

In this paper, the faulty signals of the Machines were carried out using Lab VIEW Signal Express 2012. The Accelerations and frequencies of two motors were measured. The techniques of vibration analysis, i.e. Acceleration and frequency measurement were investigated to detect both healthy and fault related signals of rotating machineries.

Total reduction of leakage power through combined effect of sleep stack and variable body biasing technique

Author: 
Md.Kamaruzzaman
Abstract: 

Leakage power consumption has become a major concern for VLSI circuit designers. Leakage power will become dominant by the year 2020 as per the report of ITRS. I propose the new approach, named sleepy stack with variable body biasing (SSVBB), which reduces the leakage current thereby saving the state of art. It uses traditional sleep transistors which are placed parallel to PMOS/NMOS between the pull up/pull down device and VDD/GND. Dual Vth can be also be applied to reduce sub threshold leakage current. It achieves exact same power reduction as zigzag approach along with saving the logic state of the circuit. Based on the experiments with the inverter as the benchmark circuit, it is found that there is 48% of reduction in delay but with the sacrifice of area. For the application which requires long idle/standby time while maintaining the logic state, the stack sleep with variable body biasing can be used.
