In this paper, we consider 2D and 3D Darcy-Stokes interface problems. These equations are related to Brinkman model that treats both Darcy’s law and Stokes equations in a single form of PDE but with strongly discontinuous viscosity coefficient and zerothorder term coefficient. We present three different methods to construct uniformly stable finite element approximations. The first two methods a...

Avian reoviruses (ARVs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. Tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. In this study, the molecularcharacteristics of ARVs in some broiler breeder flocks were investigated in...

The flow field associated with the passage of the turbulent spot in a 3–D duct with streamline divergence under zero pressure gradients was investigated and displayed as contour plots of the velocity perturbation in plan and elevation view of the spot. It suggests that, streamline divergence has no strong effect on the internal structure of the spot and eddies and their propagation in the downs...

Herein, we extend Joule-Thomson expansion to the low-dimensional regime by considering rotating Ba\~nados-Teitelboim-Zanelli (BTZ) metric in ($2+1$)-dimensional space-time. Specifically, properties of three important aspects expansion, including coefficient, inversion curve, and isenthalpic curve were studied. The divergence point coefficient zero Hawking temperature investigated. curves $T--P$...

In this paper, an audio-book, in which a professional voice talent performs multiple characters, is exploited to investigate the expressiveness of speech. The expressive speech space of the sole speaker is explored by finding the distances between acoustic models of multiple characters and the perceived proximity between their speech utterances. Using the speech of ten characters as test data, ...

this study utilizes a decade long (2005-2014) monthly data of total column tropospheric ozone (tcto) in dubson units to evaluate the spatial and temporal trend of lao over some major cities of west africa, namely lagos, accra, niamey, abuja, bamako, dakar, agadez, conakry, kano, and ouagadougou which are either capital cites or major commercial hubs, where the population ranges from 0.09 millio...

Ground penetrating radar (GPR) with a suspended 1 GHz horn antenna was deployed for measurement of soil water contents and dwatj wheat canopy reflections over bare and electrically terminating sutjaces. Sutjace reflection (SR) magnitudes and propagation times (PI) were used to independently calculate bulk soil dielectric constant and soil water contents. Measurements over wheat canopy shows tha...

A large number of calculations of the absorptive partitioning of organic compounds have been made using a number of methods to predict the component vapour pressures, p0, and activity coefficients, γi , required in the calculations. The sensitivities of the predictions in terms of the condensed component masses, volatility, O:C ratio, molar mass and functionality distributions to the choice of ...

The present study represents a comprehensive molecular assessment of some family of freshwater fishes in Iran. We analyzed cytochrome oxidase I (COI) sequences for five genus of cypriniform fishes from Iran. The present investigation provides data on genetic structure of some species of Nemachilidae including Paraschistura bampurensis, Oxynoemacheilus kiabii and Turcinemacheilus saadii and Leuc...
