SCIENTIFIC AND SPIRITUAL SIGNIFICANCE OF ADVANCED IRRIGATION TECHNOLOGY FOR INCREASING THE FERTILITY AND BIOLOGICAL ACTIVITY OF LOW LAND SLOPES OF THE SMALL CAUCASUS (As an example of the Garabagh region)

The article has been proven by the comparative analysis of long-term research results in the Karabakh region in the lowlands of the Lesser Caucasus, as well as comparative analysis of current research, as well as to the extent that these areas have been subjected to various forms of erosion. The productivity of self-cultivated agricul-tural crops has adversely affected the quality indicators and reduced productivity. At the same time, the complex physical and geographical conditions of the area, ever-increasing exogenous and anthropogenic pressures create favorable conditions for the development of all types of erosion processes in a wide range. The scientific and practi-cal application of advanced microstructure technology, as well as traditional backwatering, as well as traditional wetland irrigation, along with other complex measures in irrigated soil erosion soils, to improve fertility in erosional soils.

Influence of the Shaping Microstructure Technology and Properties of AlMgSi Alloys on Microcracks Formation under an Influence of Static Compression Loads

Endeavours were undertaken to assess metallographically AlMgSi alloys, (containing 0.58 wt% of Mg, and 0.58 wt% or 6.5 wt% of Si) in their primary states as well as after applying external loads in the Static Compression Test. During the first stage of the study the primary microstructures of the investigated samples were assessed. Samples originated from two technological processes: after strain hardening, in a form of rods (φ 9.5 mm and φ 4.0 mm) gravity casting, rolling, homogenisation and precipitation hardening; and after gravity casting in sand moulds of shaped plates 100 mm x 100 mm x 4 mm of a primary structure and after the precipitation hardening. During the second stage of investigations, microstructures of analysed samples (of various technological history) were compared - after applied external loads - in order to obtain information in what way such diversified primary structure and which of its stereological parameters (amount, shape, size and placement) are essential in initiation of microcracks under static loads.

Low-cost Rolled X-ray Prism Lenses to increase photon flux density in diffractometry experiments

At the Institute of Microstructure Technology (IMT) of the Karlsruhe Institute of Technology (KIT), a new type of refractive X-ray optics has been developed. Owing to its comparably easy fabrication method and the large aperture, the so-called Rolled X-ray Prism Lenses (RXPL) have the potential to be used with X-ray tubes in an industrial environment as a low-cost alternative to existing optics. The lens itself is built out of a micro-structured foil which is cut into shape and rolled around a winding core to form a refracting element for X-rays. The resulting refractive structure can be used as illumination optics. Diffractometry experiments with an NIST 1976a sample were performed and showed up to an 18-fold enhanced integrated intensity compared to that acquired with a steel tube collimator.
