The control-volume discrete-fracture (CVDF) model is extended to incorporate heterogeneity in rock and in rock-fluid properties. A novel algorithm is proposed to model strong water-wetting with zero capillary pressure in the fractures. The extended method is used to simulate: (1) oil production in a layered faulted reservoir, (2) laboratory displacement tests in a stack of matrix blocks with a ...

The jamming scenario of disordered media, formulated about 10 years ago, has in recent years been advanced by analyzing model systems of granular media. This has led to various new concepts that are increasingly being explored in in a variety of systems. This chapter contains an introductory review of these recent developments and provides an outlook on their applicability to different physical...

We propose a simple phenomenological model for wet granular media to take into account many particle interaction through liquid in the funicular state as well as two-body cohesive force by a liquid bridge in the pendular state. In the wet granular media with small liquid content, liquid forms a bridge at each contact point, which induces two-body cohesive force due to the surface tension. As th...

background: many azoospermic patients with non obstructive azoospermia (noa) are candidate for testicular sperm extraction (tese) and in vitro fertilization. because sperm might be present in some but not all parts of the testes of such men, multiple sampling of testicular tissue are usually necessary to increase the probability of sperm finding. sperm finding can be done by two methods: 1) cla...

Experimentos do fluxo da água usando um meio poroso não saturado compoto por diferentes sistemas de aalumina molhada não-saturada indicam que a carga superficial da partícula diminuiu com o aumento da água movimentada. O movimento máximo de água ocorreu quando a carga superficial era zero. O movimento da água foi afetado pela espessura da dupla camada elétrica no pH em que as partículas têm car...

The demand for pakcoy continues to increase as more people must be aware of their nutritional needs. One important factor in cultivation is the use planting media. main objective was find out best media combination and frequency apply fertilizers efficiency intensive growing. research conducted Cikabayan, IPB Bogor using RAL Factorial with six treatment three replications. first (rice husk, coc...

Abstract A saturation–capillary pressure relationship is proposed that applicable for all wettabilities, including mixed-wet and oil-wet or hydrophobic media. This formulation more flexible than existing correlations only match water-wet data, while also allowing saturation to be written as a closed-form function of capillary pressure: we can determine explicitly from saturation, vice versa. We...

BACKGROUND Active and passive surveillance for avian influenza virus (AIV) and Newcastle disease virus (NDV) is widespread in commercial poultry worldwide, therefore optimization of sample collection and transport would be valuable to achieve the best sensitivity and specificity possible, and to develop the most accurate and efficient testing programs. A H7N2 low pathogenicity (LP) AIV strain w...
