Back ground: Knowledge about the causes of death in children is important to evaluate health system progress and provide what is needed for an efficient design of health care delivery system. Objective: To find out the main causes of death in children under 5years & evaluate the effects of different variables like: age, gender, body weight, residency, and months of year for the causes of death. Patient& Method: This is a retrospective study which was carried out in order to find out the main causes of death among admitted children younger than 5 year in Sulaymani Pediatrics Teaching Hospital for the period of 5 years from of January 1st 2001 to December 31st 2005 included. The total numbers of admitted cases was 137,739 out of which 1455 had died. We obtained the information from case files of the deceased patients. Results: The incidence of death among admitted patients was (1.06%), the rate was higher in male gender (59.3%), while in female it was (40.7 %), with a P-value of <0.05 which is significant statistically with male to female ratio 1.48:1. Deaths were mainly in neonates (61.8 % of all age groups in the study) with a p-value of <0.05. Death was mainly in those with body weights <2.5kg, which accounts for (42.1%). The main cause of death in neonate was prematurity (54.7%) while diarrhea and Acute Respiratory Infections (ARI) were main causes during infancy (57.4%, 15.9%) respectively. Seasonal variation of died cases showed that were two peaks of death, one in June and another in November with a p-value of <0.05. The percentage of death in the rural and urban area were (64.5%, 35.5 %) respectively, with a p-value of <0.05 which is also significant. Conclusion: This study has revealed that prematurity was the main cause of death among neonate while diarrhea and acute respiratory diseases were the main causes of death during infancy. Malignancy was the least common cause of death. Deaths were mainly in neonates. There was a significant association between deaths and gender, body weight, residency& the months of the year. Key words: mortality rate, death cause, children under five.
Concrete columns with hollow-core sections find widespread application owing to their excellent structural efficiency and efficient material utilization. However, corrosion poses a challenge in concrete buildings with steel reinforcement. This paper explores the possibility of using glass fiber-reinforced polymer (GFRP) reinforcement as a non-corrosive and economically viable substitute for steel reinforcement in short square hollow concrete columns. Twelve hollow short columns were meticulously prepared in the laboratory experiments and subjected to pure axial compressive loads until failure. All columns featured a hollow square section with exterior dimensions of (180 × 180) mm and 900 mm height. The columns were categorized into

Now-a-days the Flexible AC Transmission Systems (FACTS) technology is very effective in improving the power flow along the transmission lines and makes the power system more flexible and controllable. This paper deals with the most robust type of FACTS devices; it’s a Unified Power Flow Controller (UPFC). Many cases have been taken to study how the system behaves in the presence and absence of the UPFC under normal and contingency conditions. The UPFC is a device that can be used to improve the bus voltage, increasing the loadability of the line and reduce the active and reactive power losses in the transmission lines, through controlling the flow of real and reactive power. Both the magnitude and the phase angle of th

Massive multiple-input multiple-output (massive-MIMO) is considered as the key technology to meet the huge demands of data rates in the future wireless communications networks. However, for massive-MIMO systems to realize their maximum potential gain, sufficiently accurate downlink (DL) channel state information (CSI) with low overhead to meet the short coherence time (CT) is required. Therefore, this article aims to overcome the technical challenge of DL CSI estimation in a frequency-division-duplex (FDD) massive-MIMO with short CT considering five different physical correlation models. To this end, the statistical structure of the massive-MIMO channel, which is captured by the physical correlation is exploited to find sufficiently
