Substrate, organic matter content, land use and cover may strongly affect soil properties having effect on soil water regulation services in ecosystems. Soil water holding capacity is function of specific physical, chemical, and biological soil parameters. The aim of this research was to understand the risks posed to soils and their water-holding capacities, in the face of changes in land use, land management and vegetation cover. This study was conducted in 2015, at two study sites, Tajov (TA on Haplic Cambisol) ...

Machinery from all industries is subject to aging processes. For economic and time reasons, damage cannot be repaired by replacing worn or damaged parts, but the product must be reconditioned. One of the most used reconditioning technologies in the industry is welding. Reconditioning technologies are credible, when samples are tested standardized. In most cases, welded structures have undergone various types of destructive tests: tension, compression, torsion and fatigue.[1] Since fatigue tests cannot be made duri...

In the automotive industry, but also in other sectors, since the 80s one of the most used methods of reconditioning is welding. In this way, various technologies have been developed for each batch taking into consideration their characteristics and use. To observe and determine the correctness and economic impact of these technologies, the samples must be checked by different types of destructive and non-destructive standard tests.The most demanding destructive testing on samples is the fatigue test with alternati...

Widespread use of electronic regulators, in order to correlate the working parameters at sprinkling machines imposes making a study to assess the performances of the regulation process in working conditions. To achieve this objective were pursued the following aspects: adequate choice of system components; the achievement in own conception of a electronic regulator for automatic correlation of liquid flow with displacement velocity; choosing and preparing a sprinkling machine on which will be installed the achieve...
