background: we studied the possible advantages of feed-forward control nursing model in the treatment of placenta previa. methods: we enrolled 60 pregnant women who were receiving treatment for expectant placenta previa between january 2010 and january 2016 and randomly divided them into the control group and the observation group with 30 cases in each group. in the control group, we offered sp...

in this paper, a new method is introduced for improving the efficiency of the residue number system, which uses both binary and residue representations in order to represent a number. a residue number system uses the remainder of the division in several different modules. conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

background: rounded shoulder posture is a common abnormal posture in upper quarter. kinesiotape is a new intervention that recently used in rehabilitation. there are no studies have examined the effect of kinesiotape on rounded shoulder posture. therefore the purpose of this study was to determine the effect of scapular kinesiotaping and pectoralis minor stretching exercise on forward shoulder ...

considering the importance of cd and u as pollutants of the environment, this study aims to predict the concentrations of these elements in a stream sediment from the eshtehard region in iran by means of a developed artificial neural network (ann) model. the forward selection (fs) method is used to select the input variables and develop hybrid models by ann. from 45 input candidates, 13 and 14 ...

Datalog-based systems often materialise all consequences of a datalog program and the data, allowing users’ queries to be evaluated directly in the materialisation. This process, however, can be computationally intensive, so most systems update the materialisation incrementally when input data changes. We argue that existing solutions, such as the wellknown Delete/Rederive (DRed) algorithm, can...

Background. Performing skilful movement patterns during sport practice sessions and real competition can cause negative adaptations in the musculoskeletal system. Objectives. The aim of this study was to investigate the incidence of postural abnormalities of the spine and shoulder girdle among professionals practising Sanda in Mazandaran province. Methods.
