characteristic directions of remanent magnetization of 38 samples from Upper silurian series (Hanxia Formation) along the Hexi corridor passed fold test at a 99% confidence level. The corresponding paleopole is located at 45.1°N, 5.5°E (A_(95)= 4.7°, κ=25.1), close to the Late Permian pole for this area (41.4°N, 358.6°E; A_(95)= 4.3°, κ=26.6). However, there appears an obvious difference between paleolatitudes for these two stages (6°±). Based on paleomagnetic data, it can be deduced that the Hexi corridor had probably been the western extension of the North china Block by the time of Late silurian and kept being tectonically mobile compared with the principal parts of the North china Block. In addition, paleomagnetic data reveal that the Hexi corridor experienced a southward displacement of about 600 km during the Late Paleozoic Era.

The contemporary stress field in the earth＇s crust is important and provides insights into mechanisms that drive plate motions. In this study, elastic plane stress finite element modeling incorporating realistic rock parameters was used to calculate the stress field, displacement field, and defor- mation of the plate interactions in the eastern Mediterranean. Modeled stress data for the African- Arabian-Anatolian plate interactions with fixed European platform correlate well with observed contemporary stress indicator from the world stress map （WsM） and focal mechanism of earthquakes; while displacement field agrees qualitatively well with GPs vectors and sense of motion indicated by focal mechanisms for large crustal earthquakes （Ms〉6） and plate motion models. Modeling result shows the direction of maximum horizontal compressive stress （σHmax） toward the direction of absolute motion of these plates. Large perturbations in σHmax orientations are shown to occur in and around tectonic boundaries between those plates. It is observed that, although the African plate acts mostly as indenter, which transmits the collisional motion from the Arabian plate to the Anatolian plate, in the current situation, the far-field stress, probably from the subduction in Aegean Arc, is needed to satisfy the contemporary stress field in Anatolia.

One of the very important ways to save electrical energy in the distribution system is network reconfiguration for loss reduction. Distribution networks are built as interconnected mesh networks; however, they are arranged to be radial in operation. The distribution feeder reconfiguration is to find a radial operating structure that optimizes network performance while satisfying operating constraints. The change in network configuration is performed by opening sectionalizing （normally closed） and closing tie （normally opened） switches of the network. These switches are changed in such a way that the radial structure of networks is maintained, all of the loads are energized, power loss is reduced, power quality is enhanced, and system security is increased. Distribution feeder reconfiguration is a complex nonlinear combinator- ial problem since the status of the switches is non- differentiable. This paper proposes a new evolutionary algorithm （EA） for solving the distribution feeder reconfiguration （DFR） problem for a 33-bus and a 16- bus sample network, which effectively ensures the loss minimization.

Objective\ The objective of the study was to evaluate toxicity, anti_stress activity and hepato_protective properties of Kombucha tea. Method\ Kombucha tea was fed orally for 15 days using three different doses i.e. normal dose, five and ten times the dose. Rats were then sacrificed and various biochemical, and histological parameters were estimated. Anti_stress activity was evaluated either by 1) by exposing animals to cold and hypoxia and estimating the levels of malondialdehyde and reduced glutathione in plasma/ blood or 2) by subjecting the animals to restraint stress and recording faecal output. Hepato_toxicity was induced by challenging the animals to an acute dose of paracetamol (1 gm/kg) orally and determining the plasma levels of sGPT, sGOT and MDA. Results\ The effect of oral administration of different doses of K_tea to albino rats was examined and the results indicate that K_tea has no significant toxicity as revealed by various biochemical and histopathological parameters. K_tea has been found to prevent lipid peroxidation and fall in reduced glutathione level when rats were exposed to cold and hypoxia in simulated chamber. Further, K_tea has also been found to decrease the Wrap_restraint faecal pellet output in rats. K_tea has also been found to decrease paracetamol induced hepatotoxicity significantly. conclusion\ The study shows that K_tea has anti_stress and hepato_protective activities.

Microsurgical training is imperative for urologists and clinical andrologists specializing in male infertility. success in male infertility microsurgery is heavily dependent on the surgeon＇s microsurgical skills. Laboratory-based practice to enhance microsurgical skills improves the surgeon＇s confidence, and reduces stress and operating time, benefiting both the patient and the surgeon. This review provides guidelines for setting up a microsurgical laboratory to develop and enhance microsurgical skills using synthetic and animal models. The role of emerginE techniaues, such as robotic-assisted microsureerv, is also discussed.

A genuine neurotic condition is experienced when some blood constituents accumulate on the wall of the artery get withdrew from the wall, again join the circulatory system and coagulation occur. Role of copper nanoparticles and inclined magnetic field on the peristaltic flow of a nanofluid in an annular region of inclined annulus is *** represent the clot model by considering the small artery as an annulus whose outer tube has a wave of sinusoidal nature and inner tube has a clot on its walls. Lubrication approach is used to simplify the problem. close form solutions are determined for temperature and velocity profile. Impact of related parameters on pressure rise, pressure gradient,velocity and streamlines are interpreted graphically. comparison among the pure blood and copper blood is presented and analyzed. One main finding of the considered analysis is that the inclusion of copper nanoparticles enlarges the amplitude of the velocity. Therefore, the considered study plays a dominant role in biomedical applications.

The paper presents the theoretical background for new approaches for achieving high accuracy in finish turning with slender tools. The approaches are developed especially for high-accuracy turning with vibrations- damped boring bars with a length-to-diameter ratio up to 14. The approaches are based on established force models of turning operations and utilize a three-pass scheme where the deflection of the boring bar is calculated and compen- sated for in the final passes. Very good results are achieved in practical machining tests for a great variation of cutting conditions. Experiments show that the typical diameter error is 0.01 mm, even in situation where the tool deflection is 0.3 mm.

Affordable and easy-to-use methods for assessing biomass and leaf area index （LAI） would be of interest in most breeding programs. Here, we describe the evaluation of a protocol for photographic sampling and image analysis aimed at providing low-labor yet robust indicators of biomass and LAI. In this trial, two genotypes of triticale, two of bread wheat, and four of tritordeum were studied. At six dates during the growing cycle, biomass and LAI were measured destructively, and digital photography was taken on the same dates. several vegetation indices were calculated from each image. The results showed that repeatable and consistent values of the indices were obtained in consecutive photographic samplings on the same plots. The photographic indices were highly correlated with the destructive measure-ments, though the magnitude of the correlation was lower after anthesis. This work shows that photographic assess-ment of biomass and LAI can be fast, affordable, have good repeatability, and can be used under bright and overcast skies. A practical vegetation index derived from pictures is the fraction of green pixels over the total pixels of the image, and as it shows good correlations with all biomass variables, is the most robust to lighting conditions and has easy interpretation.
