The Rouse formula and its variants have been widely used to describe the vertical distribution of sediment concentration in sediment-laden flows equilibrium. Han’s extends non-equilibrium regimes, where diffusive flux is still assumed be Fickian. turbulent flow suspension regimes downstream a mega-reservoir, e.g., Three Gorges Reservoir, usually exhibit fractal unsaturated properties, respectiv...

The Flow through saturated-unsaturated porous media is extremely important in various natural and industrial based applications. While the Darcy's law with various modifications are used to model the flow through a porous media, the flow through unsaturated porous media is largely based on conservation of mass and modified Darcy's law where non-linear relationship exists between the p...

A graph is Ramsey unsaturated if there exists a proper supergraph of the same order with the same Ramsey number, and Ramsey saturated otherwise. We present some result concerning both Ramsey saturated and unsaturated graph. In particular, we show that a cycle Cn and a Jahangir Jm Ramsey unsaturated or saturated graphs of R(Cn,Wm) and R(Pn, Jm), respectively. We also suggest an open problems.

A mild and metal-free regiodivergent addition of carbon nucleophiles to α,β-unsaturated electrophiles was developed. Total 1,2-regioselectivity was observed in the addition of nitrobenzyl chloride derivative 1 to α,β-unsaturated aldehydes 2 in the presence of TDAE. Moreover, the reaction between p-nitrobenzyl chloride 1a and α,β-unsaturated iminium salts 4 led to the formation of the 1,4-adduct...

A current challenge in unsaturated soil mechanics is the need to estimate ground heave and associated shallow foundation movements expansive soils due water content changes. Such estimation should be simple for geotechnical engineering practitioners provide reliable designs through quantifying risk with heave. The difficulties generalizing a method are related several variables influencing beha...

[1] This paper presents a class of analytical solutions for transient flow into unsaturated rock matrix. These analytical solutions are derived using specially correlated, physically meaningful relative permeability and capillary functions. The transient flow processes in unsaturated rock matrix blocks are generally described by the Richards’ equation. The analytical solutions describe the full...

The relative amounts of unsaturated fatty acids in the serum lipids of 14 patients who have undergone small bowel resection have been investigated. These results are compared with those from control subjects and also from patients suffering from cancer of the oesophagus. Both groups of patients showed patterns of unsaturated fatty acids suggesting essential fatty acid deficiency. In the resecti...

A convenient synthetic approach to α,β-unsaturated γ-butyrolactones and α,β-unsaturated γ-butyrolactams is developed. The reaction proceeds via decarboxylative iodination of paraconic acids and β-carboxyl-γ-butyrolactams, employing 1,3-diiodo-5,5-dimethylhydantoin (DIH) under irradiation, followed by dehydroiodination of β-iodo-γ-butyrolactones and γ-butyrolactams providing good yields of α,β-u...

abstract         background and objective: the relationship between diabetes mellitus and increased risk of cardiovascular diseases has been demonstrated. the aim of this study was to determine the fatty acid profile of epicardial adipose tissue in diabetic and non-diabetic patients with cardiovascular disease.          methods: in this study, 28 diabetic and 40 nondiabetic patients were evalua...
