water erosion causes severe soil damage in northern forests of iran which is associated with different rut depths in skid trails. the aim of this study was to assess rutting and soil displacement on skid trails to mitigate water erosion. therefore the research was carried out in eight parcels of district no 3 of shafarood forest in the north of iran. in order to evaluate the amount of erosion i...

Previous measures of aggressive personality have focused on direct aggression (i.e., retaliation toward the provoking agent). An original self-report measure of trait displaced aggression is presented. Exploratory and confirmatory factor analyses provided support for a 3-factor conceptualization of the construct. These analyses identified an affective dimension (angry rumination), a cognitive d...

PURPOSE To report the management of a patient, with unilateral vocal cord paralysis, undergoing thyroplasty, under general anesthesia. CLINICAL FEATURES A 25-yr-old man developed hoarseness and occasional episodes of pulmonary aspiration, caused by unilateral vocal cord paralysis. He was scheduled for thyroplasty, in an attempt to ease phonation and to decrease or prevent further episodes of ...

The coherent x-ray diffraction (CXD) method is particularly attractive for understanding structures that can be represented as phase objects. Diffraction from a crystal acquires a phase whenever atoms are displaced from lattice sites, even by small fractions of an angstrom, so CXD measured around a Bragg peak is ideal for studying strain. We have succeeded in using these coherent beams to study...

in this paper we define the notions of ultra and involution ideals in bck-algebras. then we get the relation among them and other ideals as (positive) implicative, associative, commutative and prime ideals. specially, we show that in a bounded implicative bck-algebra, any involution ideal is a positive implicative ideal and in a bounded positive implicative lower bck-semilattice, the notions of...
