designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied together with design and build a low-speed wind tunnel. a specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. there are generally three regi...

aorta is formed in a dynamic environment which gives rise to imbalances between many forces that tend to extend the diameter and length. furthermore, internal forces tend to resist this extension. impedance tomography can show this imbalance to stimulate the stenosis of aortic valve, growth of the elastic, collagen and to effectively reduce the stresses in the underlying tissue. in blood flow, ...

conclusions our study obtained some evidences on the association of micro albuminuria with diastolic dysfunction in obese normotensive no diabetic individuals. nonetheless, more assessment is necessary for obtaining a causal relationship between micro albuminuria and diastolic dysfunction. background recently, an association between impaired diastolic function and increased urinary albumin excr...

introduction: several supra spinal areas such as rostral ventrolateral medulla (rvlm) area are involved in basic cardiovascular regulation. the kolliker— fuse nucleus (kf) is located in pons and is heavily connected with rvlm. the cardiovascular effect of kf nucleus has been shown and it is suggested that kf is involved in sympathetic vasomotor tone and basic cardiovascular regulation. therefor...

conclusions the application of dn produces an improvement in ilf and clf can be prescribed for subjects with mtp in ut muscles. results statistical analysis (paired t-test) revealed significant increase in neck lateral flexion range of motion in contra-lateral side after treatment sessions in control and experimental group compared with pre-treatment score (p < 0.05). however, only dry needling...

introduction blood pressure (bp) is one of the important vital signs that need to be monitored for personal healthcare. arterial blood pressure is estimated from pulse transit time (ptt). this study uses two pulse sensors to get ptt. the aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. materials and m...

the aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. thermal efficiency is defined as a function of unknown variables (fluid pressure and vapour ...

the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

this paper presents a simplified approach to estimate the resultant force, which should be provided by a retention system, for the equilibrium of unstable slopes. the results were obtained with a developed algorithm, based on limit equilibrium analyses, that assumes a two-part wedge failure mechanism. design charts to obtain equivalent earth pressure coefficients are presented. based on the res...
