Advantages of the application of hydraulic oil filtration on barbot pumps

Due to the need of companies to reduce expenses and increase productivity, the study is based on analyzing the effectiveness of the use of filter pumps to improve the useful life of parts, components and hydraulic fluids of application in industrial slip pumps. Samples of the hydraulic oil used in the process were collected, studied and analyzed in order to demonstrate the cost benefit of the application of filter pumps.

Microcosm to macrocosm calculated with one equation, (from the variable size of elementary particles to the observation of our galaxy)

It is always speculated about the expanding of the universe because of the observable red shift. On the other hand no paper deals with the missing blue shift as a consequence of the contracting Milky Way. What is explained with the law of the inverse square of the distance, that also applies to the charge radius of atomic nuclei in the microcosm. The shrinking proton has already been reported, in 2014 for the first time in Germany (1). The scientific community was at a loss, because until then elementary particles, such as the proton in size, were handled as a constant in nature.

Statistical analysis of weld repair length in aerospace pressure vessels

Welding is a governing process in realization of aerospace pressure vessels. In defence and aerospace industry, ultrahigh strength materials viz maragingsteel is being used for realization to meet the mission requirements. The fracture based design is adopted for pressure vessels. The quality of welding is ensured by qualifying the welding process, through procedure qualification, use of qualified welders and Non-destructive testing. Weld joints are inspected using Non destructive testing such as Radiography testing, Ultrasonic testing, Die penetrant testing etc.

Characterization of court decisions for crimes committed in a context of domestic violence after the maria da penha law

Importance: The Maria da Penha Law (Federal Law 11340/2006) is an important legal instrument which institutionalized the issue of domestic and family violence against women in Brazil, conceptualizing and giving visibility to the hidden violence within the family environment, and acknowledged the responsibility of all people, and mainly the State’s, in guaranteeing and protecting women rights, with the creation of mechanisms to restrain and prevent all forms of violence against them.

Expert optimization and prediction of bead volume of mild steel butt welded joint

The volume of weld bead deposit on a welded joint, has a lot to say about the integrity of the weldment during its service life.Residual stresses, cracks etc can be greatly initiated with large weld bead. In this study, central composite design matrix was employed using Design Expert 7.01 software. A total of 20 sets of experiments were produced, the weld specimen was mild steel plate measuring 60mm x 40mm x 10mm.

Effective minimization of construction waste in Maharashtra

The project is based on the recycling of the rapidly increasing construction and demolition waste. Through this process we want to take a step ahead, the idea of stopping illegal sand mining, earth excavation and ultimately save our mother Earth from destruction. The cost of recycled sand and aggregates is lower than conventional aggregates and sand, resulting in reduction of overall construction cost.

The bacterial flora of the medical leech (hirudo verbana, carena, 1820) in karagöl (kahramanmaraş)

This study embraces the bacterial flora of medicinal leeches in Karagöl (Kahramanmaraş). For this purpose, we took samples of blood, stomach, intestine and mouth from the leeches (Hirudo verbana), which were captured in the autumn and winter of 2016 and spring and summer of 2017 in Karagol, at the laboratory. For the isolation of the bacteria; Tryptic Soy Agar (TSA) and Brain Heart Infusiyon Agar (BHIA) was used. These media were incubated in an incubator at 24°C for 48 hours.

Study of amphibia fauna of bundelkhand region with special reference to Damoh District

The pollutants and drastic environmental variation have also adversely effected and changed water qualities i.e. colour, hardness, turbidity , alkalinity, pH. COD, BOD and TDS etc. Aquatic life, thus, also is affected. Changes in morphology of amphibian, like- colour, pigmentation, length, weight mass, etc. may occur. This can not be ignored that the afore-mention variation may be responsible to develop new varieties or sub species. Unfortunately, negligible work is done in relation to amphibian fauna of the area in recent-past.

Biochemical and anthropometric profile of wistar rats treated with palm oil (Elaeis guineenses)

Obesity is considered a pandemic and is associated with numerous health risks such as dyslipidemia, hypertension, overweight/obesity and metabolic syndrome, which are risk factors for cardiovascular diseases (CVD). The bioactive compounds present in fruits, vegetables and oilseeds have biological effects on glycemic control, cholesterol levels, body weight, and therefore on CVD prevention. Elaeisguineenses is a palm of African origin, and from its fruits, it is possible to extracted oil. The fruits have an excellent repertoire of phytochemicals, carotenoids, tocopherols, and tocotrienols.

Human resources in the technological innovation of farming systems for sheep production in the west of Mexico

Technology in farming systems has been considered an element for agricultural development, needed to increase the competitiveness. Nevertheless, it’s study has ignored the human resources role in technological innovation. The study’s goal was to determine the human resources’ influence in technological innovation in sheep production systems in the towns of Epitacio Huerta and Contepec, Michoacan, Mexico. The information was gathered from 47 production units and the data was analyzed by frequency analysis and Rho correlation from Spearman.
