The Enskog kinetic theory for moderately dense gas-solid suspensions under simple shear flow is considered as a model to analyze the rheological properties of the system. The influence of the environmental fluid on solid particles is modeled via a viscous drag force plus a stochastic Langevin-like term. The Enskog equation is solved by means of two independent but complementary routes: (i) Grad...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...

Modified Newtonian dynamics, a successful alternative to the cosmic dark matter model, proposes that gravitational field deviates from the Newtonian law when the field strength g is weaker than a critical value g0. We will show that the dynamics of MOND can be derived from an induced gravity model. New dynamics is shown to be compatible with the spatial deformation of scalar fields coupled to t...

In the very beginning stage of the lung changes are Perivascular, capillary wall edema, thickening of the interstitial, lymph and vascular dilatation.  In the late stage of the shock the following changes will occuree  Microthromboses of the lung capillary, polynulcear in­filtration into the interstitial, the existence of polynu­clear in the alveoli, proliferation of interstitial mesenchy­ma,...

The aim of this study was to assess the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) for the differentiation of peritoneal thickening of undetermined origin. This retrospective study included 103 patients (44 men and 59 women, age 59.2 ± 14.8 years) who had undergone 18F-FDG PET/CT for the evaluation of peritoneal thickening of undetermined o...

Shear-Thickening Fluids (STFs) are a special Non-Newtonian Fluid that act like a solid when they experience a force. A simple example of this is a mixture of cornstarch and water. In this experiment, I text this mixture’s STF properties by using a ball drop to simulate an impact. By varying the ball drop height (and thus the force upon impact), and observing the bounce height, I determined wher...

Thickening of basal lamina' (BL) which occurs with advancing age (1) and various diseases (4, 7, 10) is most common and severe in patients with diabetes mellitus (2, 8, 6, 12, 14) . The reasons, for. and the mechanism of this thickening have thus far escaped satisfactory explanation . In this communication, we wish to provide new evidence which elucidates the development of thick BL and which d...

Ultrasound has been used to measure diaphragm thickness (Tdi) in the area where the diaphragm abuts the rib cage (zone of apposition). However, the degree of diaphragm thickening during inspiration reported as obtained by one-dimensional M-mode ultrasound was greater than that predicted by using other radiographic techniques. Because two-dimensional (2-D) ultrasound provides greater anatomic de...

This paper presents a new interpretation of the geometry of Triassic alignment of J. Sidi Mahdi –J. Zitoun in Medjerda Valley Plain (Northern Tunisia) based on detailed analysis of gravity and seismic reflection data. The main results of gravity analysis do not show a distinguish gravity anomaly over Triassic evaporites bodies. The positive gravity anomaly seems to be related to the entire stru...

Mixtures of powder and liquid are ubiquitous in nature as well industries exhibit complex flowing deforming behaviors, including sol to gel transition under shear stress. In order better understand the characteristic features this type mixture, we observed behavior a mixture colloidal silica particles water model system vibration. The showed different states, from powder-like viscous fluid-like...
