Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...

Several studies have been performed to evaluate the desertification in Iran andother countries which led to present national and regional models. One of them is IMDPAmodel. This model was used as a case study in Taraz Nahid, Saveh, Iran. In this study, fivefactors including climate, soil, vegetation, irrigation, and socioeconomic ones wereevaluated. According to the region conditions for each c...

to evaluate genetic variation and to study of dry matter remobilization towards seed, 64 bread wheat genotypes were examined in two separated experiments using alpha-latic design of 2 replications during 2002–2003. significant differences observed for most traits in normal and drought conditions. there were considerable variations among genotypes for independent parameters of dry matter remobil...

landmark based geometric morphometrics and comparison of meristic characters was used to understand potential differences between populations of waspi in mashkil and mokran basins. 97 specimens of waspies were caught (64 from mashkil river and 33 from sarbaz river). 14 landmarks were digitized on pictures taken from left side of specimens and meristic characters were counted. data were analyzed...

This is a follow-up of our recent article Deng et al. (2004). In Deng et al. (2004), we derive some local geometric conditions on vortex filaments which can prevent finite time blowup of the 3D incompressible Euler equation. In this article, we derive improved geometric conditions which can be applied to the scenario when velocity blows up at the same time as vorticity and the rate of blowup of...

Human movement has been found to have positive effects on learning performance. This study examined the effects of using Dynamic Geometry Software (DGS) CABRI to manipulate geometric properties of triangles or observing those manipulations made by an instructor on learning geometric properties with DGS-CABRI. Participants were 60 year 5 students, who received instructions on geometric problems ...

We demonstrate that the internal magnetic states of a single nitrogen-vacancy defect, within a rotating diamond crystal, acquire geometric phases. The geometric phase shift is manifest as a relative phase between components of a superposition of magnetic substates. We demonstrate that under reasonable experimental conditions a phase shift of up to four radians could be measured. Such a measurem...

This paper describes an optimized method for factorizing multivariate polynomials over algebraic extension fields. The proposed method is applied to solving several selected problems in automated geometry theorem proving, decomposition and implicitization of geometric objects, and verification of geometric conditions. Some performance comparisons between this and other related methods are repor...

twenty five durum wheat lines were evaluated under drought stress and non-stress conditions employing randomized complete block design of 4 replications. significant differences were observed among the lines for most traits in either stress or non-stress conditions. correlation analysis under non-stress conditions indicated that grains per spike and number of spikes per m2 and while under stres...
