Objective: To assess the nutritional status of hemodialysis patients.
Methodology: A descriptive quantitative cross sectional study was effectuated in hemodialysis centers from
February 2011 to September 2011. A purposive "non-probability" sample of (70) male and female hemodialysis
patients in al-Najaf al-Ashraf Governorate from those who have spent more than six months on maintenance
hemodialysis schedule. Data collected through using of a well-designed questionnaire consist of five parts, part
one consists of sociodemographic contain (9) items, and part two consists of medical data contain (8) items, and
part three consists of health and nutrition behavior contain (12) items plus (8) items of anthropometric
measurements, and part four consists of food frequency contain (5) major items, and part consist of laboratory
investigation contain (9) items. In addition to food diary (24 hour dietary recall) used for validating the food
frequency part. Data collected by direct interview method with ESRD on maintenance hemodialysis patients’ also
by anthropometric measurement method and blood sample for laboratory investigation. Reliability of the
questionnaire was determined through pilot study and validity determined through a panel of experts consists of
(18) experts. Data was analyzed by using of descriptive data analysis (frequencies, percentages, mean, standard
deviation and relative sufficiency) and by using of inferential analysis (correlation coefficient, t- test and χ²).
Results: The study results indicates that the majority of study sample suffer from moderate malnutrition
according to several indicators including anthropometric measurements, laboratory investigations and (type and
quality) of food. Most of study sample was illiterate, and the sample divided between male and female with
invisible variance between percentages, the majority of study sample was nutritionally instructed but they don’t
reflect the desired compliance.
Recommendations: The study recommends with the necessity of establish a nutritional health style for
hemodialysis patients including several dialogist like calibrating of dietary intake, increase physical exercise as
tolerated, control body weight and enrich the list of laboratory investigations. Workout anew studies about the
studied phenomenon, activate the role of dietician (doctor and nurse) in hemodialysis centers, hemodialysis
malnutrition alert day and initiate a proper financial support through establish a hemodialysis malnutrition
foundation work for improvement of socioeconomic status and nutritional status through study subjects

Bipedal robotic mechanisms are unstable due to the unilateral contact passive joint between the sole and the ground. Hierarchical control layers are crucial for creating walking patterns, stabilizing locomotion, and ensuring correct angular trajectories for bipedal joints due to the system’s various degrees of freedom. This work provides a hierarchical control scheme for a bipedal robot that focuses on balance (stabilization) and low-level tracking control while considering flexible joints. The stabilization control method uses the Newton–Euler formulation to establish a mathematical relationship between the zero-moment point (ZMP) and the center of mass (COM), resulting in highly nonlinear and coupled dynamic equations.

Little is known about hesitancy to receive the COVID‐19 vaccines. The objectives of this study were (1) to assess the perceptions of healthcare workers (HCWs) and the general population regarding the COVID‐19 vaccines, (2) to evaluate factors influencing the acceptance of vaccination using the health belief model (HBM), and (3) to qualitatively explore the suggested intervention strategies to promote the vaccination.
This was a cross‐sectional study based on electronic survey data that was collected in Iraq during December first‐19th, 2020. The electronic surve

Background: The best material for dental implants is polyetherketoneketone (PEKK). However, this substance is neither osteoinductive nor osteoconductive, preventing direct bone apposition. Modifying the PEKK with bioactive elements like strontium hydroxyapatite is one method to overcome this (Sr-HA). Due to the technique's capacity to provide better control over the coating's properties, RF magnetron sputtering has been found to be a particularly useful technique for deposition.
Materials and methods : With specific sputtering conditions, the RF magnetron technique was employed to provide a homogeneous and thin coating on Polyetherketoneketone substrates.. the coatings were characterized by Contact angle, adhesion test, X-ray dif

Software-defined networks (SDN) have a centralized control architecture that makes them a tempting target for cyber attackers. One of the major threats is distributed denial of service (DDoS) attacks. It aims to exhaust network resources to make its services unavailable to legitimate users. DDoS attack detection based on machine learning algorithms is considered one of the most used techniques in SDN security. In this paper, four machine learning techniques (Random Forest, K-nearest neighbors, Naive Bayes, and Logistic Regression) have been tested to detect DDoS attacks. Also, a mitigation technique has been used to eliminate the attack effect on SDN. RF and KNN were selected because of their high accuracy results. Three types of ne
