The aqueous extract of leaves of Parkia biglobosa (Pb) is used in Africa to cure hypertension or for the treatment of immunocompromised individuals. To avoid intoxication of consumers, our study was carried out to evaluate the action of the extract on the level of glucose and liver enzymes [Akaline phosphatase (ALP), Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT)]. Two sets...

There is a need to shield from the wind improve pedestrian comfort in urban environments. Perforated windbreaks, such as fences, vegetation or textile nets, have proven be an efficient solution, whereas knitted textiles not yet been explored. The purpose of this study was evaluate capacity windbreaks reduce velocities, inform further research and promote wider architectural applications. Five c...

anatomical vascular variations are rare causes of carpal tunnel syndrome. an aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. this article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radial...

Women with mammary hypertrophy who present for reduction mammaplasty have several well-described musculoskeletal complaints, but a high prevalence of carpal tunnel syndrome has not been reported. We identified 151 patients from a plastic surgery practice who underwent reduction mammaplasty from 1994 to 1996. To this group we added a convenience sample of 64 women volunteers with relatively smal...

This paper deals with full face excavation of large size tunnels in rock masses of very poor quality which exhibit squeezing problems. Three different time dependent constitutive models of increasing complexity (a viscoelasticplastic model, an elastic-viscoplastic model, and an elastic-plastic-viscoplastic model) are used to analyze the tunnel response during excavation of the Saint Martin La P...

Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

High speed wind tunnels are widely used in the study of fluid flow behavior around various objects. The air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. To arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. ...

The similar material plays an important role in Geo-mechanical model test, and the proportion influences the test results directly. According to the physical and mechanical properties of the prototype, the cementitious material with good elastic-plastic for iron crystal sand (ISBM) was chosen as the similar material for the research on failure mechanism of surrounding rock under the environment...

The safety factor of rock mass surrounding tunnel can be determined using the strength reduction method (SRM), furthermore, it is very important to solve criterion critical state. For stability estimation tunnel, there need discuss that preferable use same criteria for slope stability, such as non-convergence finite element calculation, penetration plastic strain and sudden change horizontal di...
