newcastle disease (nd) is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. in this experiment nd virus (ndv) was inactivated by two different chemicals binary ethylenimine (bei) and formaldehyde. formaldehyde was used at 0.1%, while bei was used at concentrations of 1 to 4 mm. ndv inact...

Circumbinary disks are considered to exist in a wide variety of astrophysical objects, e.g., young binary stars, protoplanetary systems, and massive binary black hole systems in active galactic nuclei (AGNs). However, there is no definite evidence for the circumbinary disk except for some in a few young binary star systems. In this Letter, we study possible oscillation modes in circumbinary dis...

density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (dea) and methyl diethanolamine (mdea) with water have been measured at different temperatures from 288.15 k to 323.15 k at atmospheric pressure. also, this study presents the effects of mixture composition and temperature upon these thermo- physical properties. to measure the density and refractive i...

in order to the enhancement of the quality of speech corrupted by additive noise, a speech enhancement method has been put forward based on the combination of spectral subtraction and binary masking. spectral subtraction is a powerful method for removing noise from speech and binary masking provides essential elements to be used in monaural speech segregation. in the proposed combined method, f...

Abstract. Consider a fluid composed of two species of particles, where the interparticle pair potentials u11 = u22 6= u12. On confining an equal number of particles from each species in a cavity, one finds that the average one body density profiles of each species are constrained to be exactly the same due to the symmetry, when both external cavity potentials are the same. For a binary fluid of...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

The purpose of this qualitative study was to examine the value of different methods of making meaning in music therapy improvisations. Six research participants met with the researcher and created solo and duo improvisations. Each improvisation was subjected to four methods of meaning-making: participant journals, researcher journals, dialogues, and musical analysis using the Improvisation Asse...

How can dangerous interference with the climate system be avoided? Science can help decision-makers answer this political question. Earlier publications have focused on the probability of keeping global mean temperature change below certain thresholds by stabilizing greenhouse gas concentrations at particular levels. We compare the results of such ‘‘stabilization profiles’’ with a set of ‘‘peak...

This is a descriptive, quantitative, and hypotheses testing study conducted on entrepreneurial and professional CEOs. This study has a particular interest in small medium enterprises (SMEs) because it constitutes the core of our economy and is a major factor of social composition. The purpose of present study is to investigate and explore differences on the motivational profile of Pakistani ent...
