Spatial characterization and interpolation of precipitation data

Being able to accurately predict point or a real precipitation data at unsampled locations or areas using measured precipitation data is important in the work of agriculturists, hydrologists, climatologists, engineers, and others. Precipitation phenomenon is a complicated process due to the spatial variability, uncertainty, and complexity of the meteorological processes underlying its formation.

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.

Electronic biomedical dynamometer for measurement, analysis and registration of palmar force and force information in time

The developed electronic biomedical dynamometer was able to measure palmar grip strength and varying forces over time in people whose physical capacity ranges from 0 N up to 1400 N. The mechanical structure is composed of two cylindrical PVC rods, two steel supports, one finger backing, other backing for the palm of the hand and a dynamometric ring containing resistive extensometers.

Telomers and the effect of the practice of physical exercises in their course

This article aims to explore the effect of telomerases on the shortening of telomeres in people who perform physical activities in high, medium and low intensities and to diagnose what would be the best results obtained in them. It is known that the telomeres are the ends of the cellular structure of the DNA that, as its aging, its ends are shortening and degenerating, causing in the senescence of the cell.
