abstract backgrounds: subacromial impingement is a common cause of shoulder pain and many patients with this condition recover with conservative management. the most commonly used modalities of nonoperative treatment include activity modification, anti-inflammatory medication and subacromial injection of steroid and ultrasound and physical therapy programs. this study assessed the value of phys...

in this paper, we use petrov-galerkin elements such as continuous and discontinuous lagrange-type k-0 elements and hermite-type 3-1 elements to find an approximate solution for linear fredholm integro-differential equations on $[0,1]$. also we show the efficiency of this method by some numerical examples

‎in this paper, we discuss about existence of solution forintegro-differential system and then we solve it  by using the petrov-galerkin method. in the petrov-galerkin method choosing the trial and test space is important, so  we use alpert multi-wavelet as basisfunctions for these spaces. orthonormality is one of theproperties of alpert multi-wavelet which helps us to reducecomputations in the...

background & aim : ventilator associated pneumonia (vap) is the most common infections in critical care units, which leads to more length of hospital stay, costs, and high mortality. therefore, prevention is a priority according to clinical guidelines. the aim of this study is determine the effects of passive versus active implementation of vap guidelines on nurses’ performance in critical care...

Most statistical methods for censored survival data assume there is no dependence between the lifetime and censoring mechanisms, an assumption which is often doubtful in practice. In this paper we study a parametric model which allows for dependence in terms of a parameter delta and a bias function B(t, theta). We propose a sensitivity analysis on the estimate of the parameter of interest for s...

Thematic structure, an important factor for textual metafunction, plays a significant role in inspecting and promoting the textual coherence. With a theoretical statement of Thematic theory and TP patterns, this paper proposes the feasibility of the Thematic Operational Approach in the teaching of college English writing. This approach is proved to not only strengthen students’ application awar...
