In this paper we suggest new method to estimate the missing data in bivariate normal distribution and compare it with Single Imputation method (Unconditional mean and Conditional mean) by using simulation.

Abstract:
Objective (s): This study aims to assess nurses' knowledge and practice regarding physiotherapy protocol at intensive care units
Methodology: descriptive cross-sectional study design executed at the ICU in the city hospitals of AL- for the time of 13th October/ 2021 to 7th April /2022. Questionnaire filled by 75 nurses who work in ICU who had chosen by non-probability (purposive) selection collected the data. Then the researcher used an observational checklist to evaluate nurses’ practice. The data was analyzed using descriptive statistics and SPSS.
Results: the study found a deficit in nurses’ knowledge and pra

Show MoreIn this study, Titanium Dioxide Nanoparticles were synthesized by an easy and eco-friendly technique (green synthesis) using green tea leaves (Camillia sinensis), Nanoparticles were analyzed using structural and optical analysis, the X-ray pattern showed that Titanium Dioxide NPs had a tetragonal structure with (Face Centered Tetragonal) FCT crystal structure, the UV-visible recorded an absorbance peak near 350 nm and calculated energy band gap was 3.5 eV, all measurements were proved the purity and Nano size of prepared Nanoparticles. Biochemical parameters evaluation also mentioned in this research, these analyzes showed that Titanium Dioxide nanoparticles in particular dose (50 mg/kg) have the ability to reduce blood glucose
... Show MoreNonparametric methods are used in the data that contain outliers values. The main importance in using Nonparametric methods is to locate the median in the multivariate regression model. It is difficult to locate the median due to the presence of more than one dimension and the dispersion of values and the increase of the studied phenomenon data.The genetic algorithms Minimum Weighted Covariance Determinant Estimator (MWCD), was applied and compared with the multilayer neural network Back propagation to find the estimate of the median location based on the minimum distance (Mahalanobis Distance) and smallest specified for the variance matrix. Joint Minimum Covariance Determinant (MCD) as one of the most nonparametric methods robust. The stud

Show MoreThe study of cuneiform texts is very important for finding out the ancient history of Iraq and its civilization, as well as the close relation among languages, especially Semitic, the mother language to which both Akkadian and Arabic belong, the matter that clarifies the linkage among them. The Akkadian language is among these Jazri (a Semitic branch) languages, besides Arabic. It is the most ancient one. It consisted of a lot of genuine linguistic rules derived from the mother Jazri language. Contrastive Akkadian studies approved these linguistic rules. Due to the close linkage that relates Akkadian language to its sister Arabic , as they both relate to the same family, the researcher an verbs and compared them with studied aspects and moo

... Show MoreThis semiotic analytical study has shown that there is a wide diversity in the aesthetic systems and the ranges of reception for the rhetoric and the discourse. The fertility of this semiotic conceptual system monitored this new mature, innovative and advanced level of this new critical analytical method with its different technical and theoretical foundations. Thus, it opened the door wide to new discoveries in the laws, which motivate different artistic texts. Finally, the research is just a start. Can the linguistic methods read the artistic works outside the linguistic authorities? Is it possible to capture the structural transformation in Picasso drawings? Semiotically another researcher in another method (such as deconstruction) ca

The aim of this study is to investigate the pull-out tests to check the interfacial strength of the polymer composite in two cases, with activation NiTinol wire and without activation. In this study, shape memory alloy NiTinol wire 2 mm diameter and linear fully annealed straight shape were used. The study involved experimental and finite element analysis and eventually comparison between them. This pull-out test is considered a substantial test because its results have a relation with behavior of smart composite materials. The pull-out test was carried out by a u

The aim of research is to know the effect of using various exercises in developing endurance of strength and effect in developing two skills. dragging of defense and movement of defender player. The two researchers proposed that there are differences that have statistic function between post-test and pre-test for two experimental and control groups. The experim
