The present work is aimed at assessing the Physico-chemical characteristics of Back Water and Flow Water of Saradgi Barrage and the Water Quality Index (WQI) of both the water of Bhima River near Saradgi village of Taluka-District Kalaburgi, Karnataka State, India. Surface water samples were collected at two sampling points, S1 upstream side of barrage saradgi, and S2 downstream side of village saradgi. The samples are subjected for physico-chemical analysis and eleven parameters have been considered for study namely; pH, Total Dissolved Solids, Total Hardness, Chloride, Nitrate, Sulphate, DO, BOD, Alkalinity, Phosphate, Electrical Conductivity.................

Today corruption as a phenomenon represents one of the serious threats to every country. It means that instead of law and its norms, individuals govern managed by selfish goals and interests. It is a form of the law within which dominates egotism and is accompanied by inciting (most often business) interests. It is a situation that socially and in practice negatively affects the total development of the country, slowing economic processes, aggravating the social security and undermining the notions and believes in the value of principles, especially the principles of legality, parity, equality and freedom. Corruption is established in a form of hidden and illegitimate redistribution, and abuse of power and authority.................

In this study applications and potential uses of 3D printing in the plastic thermoforming industry are studied. Additive manufacturing has revolutionized the modern manufacturing process and engineering design process. Thermoforming is widely used in plastic manufacturing industries to produce a range of polymer products such as products in the packaging industry. Thermoforming moulds are mostly produced using conventional mould building technologies and are made of steel. These mould are robust but only suitable for mass production and take some time to fabricate. 3D printing can find use in thermoforming industry in creating.................

In this research, Finite Element Modeling (FEM) using SYSWELD was carried out to predict thermal cycles, residual stresses in type X70 oil and gas pipeline sheet weld joint made by TIG welding process. Residual stress were measured using ultrasonic technique (UT) and validated by simulated residual stress profiles. The simulated thermal cycles were validated by thermal cycles measured using thermocouples fitted at 4, 6 and 8 mm from weld line. For modeling, arc voltage, welding current, welding speed, type of thermal source were considered as input parameters and residual stresses and thermal distribution.................

The objective of this experimental study is to investigate fatigue and impact strength dissimilar weld of MONEL 400 to AISI 304 joints by TIG welding. Five independent input parameters of TIG welding viz., welding current, V grove angle of joint, filler rod material, filler rod diameter and welding speed have used to explore the influence on fatigue strength and impact strength of joint. The regression equation, and ANOVA have developed using the experimental data and graphs were plotted to investigate the effect of process variables on response characteristics by using response surface methodology. It has observed that Fatigue Strength of welding joint is increases by increase both joint angle and welding current. The Impact Strength of welding joint is decrease by increasing diameter of filler rod.

The concepts of using fibres in order to reinforce matrices weak in tension is more than 4500 years old.since Portland cement concrete started to be used widely as a construction material attempts were made to use fibres for arresting cracks enhance the strength etc. The development of fibre reinforcement for concrete was very slow before 1960's. Fibers are generally used as resistance of cracking and strengthening of concrete. In this project we are going to compare the compressive strength of 3, 7 and 28 days of aramid fibres to the ordinary concrete and fibre reinforced concrete i.e. glass fibres and steel fibres. The concrete is design for M20 grade of concrete. According to various research papers, it has been found that steel fibers give the maximum strength in comparison and glass fibre is used for crack.................

In the development of engineering science, material engineering plays a pioneering role. In the use of material, the proper use of the structure also brings to the great efficiency. Composite materials, especially composite sandwich panels have shown outstanding advantages in many fields in engineering, therefore, the calculation to determine their mechanical behavior is very necessary. There have been many authors suggesting methods for calculating sandwiches, but with large and unsymmetrical sandwich panels, these methods are still very difficult. In this paper, we present a method to build an equivalent model (2D) that can be used to determine mechanical behavior of sandwich panels and replaces to original model (3D)..................

Barium oxalate crystals have been grown by gel method using agar gel as a media of growth at ambient temperature using single diffusion technique. Best results were obtained when a gel was set by mixing a solution of different concentration and quantity of ammonium chloride as an additive. A single crystal of about 10 times larger than the crystal obtained in various other methods at the interstitial in a tube associated 8.5 mL NH4Cl additive solution. Various polarization mechanisms such as atomic polarization of lattice.................

BThe Schiff base complexes Co(II), Ni(II) and Cu(II) of salicylaldehyde and 1 naphthyl amine were synthesized and characterized by elemental analysis, conductivity measurements, electronic, infrared, SEM, spectral measurements and antibacterial studies. The conductance measurements indicate that all the complexes are non-electrolytes. The results indicate that the metal complexes of Ni(II), Co(II) and Cu(II) are hexacoordinated and have moderate antibacterial activity.
