Introduction: According to the Covid-19 epidemic, quality of services in medical centers are importance. Therefore, the present study was conducted to investigate the status of improving the quality of diagnostic services in corona pandemic conditions in medical centers using the Parasuraman model. Methods: The present applied research is a descriptive correlation. The statistical population...
Noise, Vibration and Harshness (NVH) is a critical consideration in the design of automotive and aerospace vehicles for comfort, and fatigue of components arising from interior structural and acoustic pressure fluctuations due to external structural or acoustic loading. In the low to mid frequency range, current NVH models, obtained by direct, unsymmetric, coupled Eulerian Finite Element discre...
Nowadays, huge volumes of Web data are organized or exported in tree-structured form. Popular examples of such structures are product catalogs of e-market stores, taxonomies of thematic categories, XML data encodings, etc. Even for a single knowledge domain, name mismatches, structural differences and structural inconsistencies raise difficulties when many data sources need to be integrated and...
Several characterizations of weak cotype 2 and weak Hilbert spaces are given in terms of basis constants and other structural invariants of Banach spaces. For finite-dimensional spaces, characterizations depending on subspaces of fixed proportional dimension are proved.
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...
let r be a right gf-closed ring with finite left and right gorenstein global dimension. we prove that if i is an ideal of r such that r/i is a semi-simple ring, then the gorensntein flat dimensnion of r/i as a right r-module and the gorensntein injective dimensnnion of r/i as a left r-module are identical. in particular, we show that for a simple module s over a commutative gorensntein ring r, ...
Two new polymeric compounds of cadmium acetate using two isomers of pyridine hydrazide ligands have been synthesized and characterized by X-ray diffraction analysis. Structural analysis shows that both compounds were crystallized in monoclinic crystal system with P21/c space group. Coordination polymer [Cd(OAc)2(L1H)]n (1) which L1H is para pyridine hydrazide, has two dimensional sheets with re...
this study focused on the effect of teaching collocations on the awareness of two affective dimensions, evaluation and potency dimensions, of deep vocabulary knowledge as well as the general vocabulary knowledge of efl students. sixty intermediate efl female adult learners participated in this study; they were chosen among 90 students through the pet and a general vocabulary knowledge test. the...
