the growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (md) process, as a promising separation technology, has recently gained more attention. the md process is a non-isothermal membrane-based separati...

We compute the scattering amplitude in Wilson Chiral Perturbation Theory for two flavors. The lattice spacing effects due to the explicit chiral symmetry breaking are kept through O(a2), and we consider the regime where the quark mass m is of order aΛQCD. Analytic expressions for the scattering lengths in different isospin channels are given. As a result of the O(a2) terms the scattering length...

We study the classical cosmic string solution in a theory with dynamical U(1) symmetry breaking. We calculate the energy per unit length of the string and compare it to that obtained in a model with a fundamental Higgs. We find that the predictions of the standard Abelian Higgs model are quite stable towards the addition of higher dimension operators expected in the effective Lagrangian for the...

The Direct Anterior Approach for Total Hip Arthroplasty By E. Marc Mariani, MD, and Michael H. Bourne, MD Background The direct anterior approach to total hip arthroplasty offers several advantages, including utilization of the supine position, use of anatomical intervals for soft-tissue preservation, and use of intraoperative fluoroscopy for verification of acetabular and femoral prosthetic po...

We apply the theoretical formalism developed by us earlier @M. Vergeles and G. Szamel, J. Chem. Phys. 110, 6827 ~1999!# to study density, temperature, and bond-length dependence of the dynamic friction on a molecular bond. We show that the theory reproduces all the trends seen in molecular dynamics ~MD! simulations. The theoretical predictions agree reasonably well with the results of MD simula...

Matrix-free nanocomposites made from polymer-grafted nanoparticles (PGN) represent a paradigm shift in materials science because they greatly improve nanoparticle dispersion and offer greater tunability over rheological mechanical properties comparison to neat polymers. Utilizing the full potential of PGNs requires deeper understanding how polymer graft length, density, chemistry influence inte...

Marek's disease (MD) is the most common lymphoproliferative diseases of chickens; During the last year the incidence of MD was  investigated among slaughter houses and suspected broiler farms, located in  Isfahan (Iran) as the region of  highest density of poultry husbandry by histopathology,  For subclinical MD investigation, in  total 1550 chickens originated  from slaughter houses  were exam...

The influence of operating variables [viz: temperature 55-85°C, process time 30-120 min, pH 9-11,peraceticacid concentration 0.5-3.5% oven dried pulp (o.d.p.)., and sodium perborate concentration 1-5% o.d.p.] on the bleached pulp characteristics [viz: viscosity (VI), brightness (BR), kappa number (KN)], and resulting paper sheets properties [viz: breaking length (BL), stretch (ST), tear (TI), a...
