Improving the Accuracy of Prayer Times and Calculating Their Change with Geographical Latitudes during the Year 2021 AD

       The entry time of the prayer in Islam is a prerequisite condition for performing obligatory prayers, and prayer times to be performed in Islam coincides with the time changes of the position of the sun. The elliptical and equatorial coordinates of the sun were calculated for different latitudes. The prayer times for the city of Baghdad were calculated at (latitude = 33.34º N, longitude = 44.43 E) with high accuracy for the year 2021 AD. The results showed that all prayer times are affected by latitude according to each region except (Dhuhr prayer (, it changes with the change of the equation of time, because the equation of time does not depend on latitude, but rather on the sun’s declination, which depends on date. We also made improvements to the accuracy of calculating prayer times, where the disappearance of evening twilight (Isha prayer) was calculated when the sun was below the western horizon at an angle of (170 ) and for )Fajr prayer( at an angle of (180) below the eastern horizon. Minutes were added to enable entering the time for )Dhuhr prayer( (5 minutes) and )Asr prayer( (3 minutes).

The results show that the shadow of the meridian varies every day of the year from one point to another on the surface of the globe, so it is non-existent if the sun is perpendicular to the earth at the time of the meridian, and it has a specific length if the latitude of the place exceeds the value (23.50) the Tropic of Cancer or the Tropic of Capricorn), and its length increases as we move towards higher latitudes.

In addition, the results of our program were compared with the program of the Islamic project for all prayer times for the cities of Baghdad and Mosul for one year, and it showed a good match for the results, with a difference in some times and days of no more than one minute due to the modifications we added to calculate the effect of altitude above sea level. Practical observation was also conducted to check the times of the Dhuhr, Asr and Maghrib prayers for several days during the year 2021 AD, and the results were identical with our theoretical results.

IMPROVING THE ANTIBACTERIAL ACTIVITY BY THE COMBINATION OF ZIRCONIUM OXIDE NANOPARTICLES (ZrO2) AND CEFTAZIDIME AGAINST KLEBSIELLA PNEUMONIAE

Klebsilla pneumoniae is one of must opportunistic pathogens that causes nosocomial infection, UTI, respiratory tract infections and blood infections. ZrO2 nanoparticles have antimicrobial activity against some pathogenic bacteria and fungi. Ceftazidime is one of third generation cephalosporins groups of antibiotecs, characterized by its broad spectrum on bacteria in general and particularly on Enterobacteriaceae family like Klebsiella spp. Method: Diverse clinical samples of Klebsilla pneumoniae were isolated from several hospitals in Baghdad – Iraq and ZrO2 nanoparticles was investigated against it. Ceftazidime was also investigated against K. pneumoniae. Both of ZrO2 nanoparticles and ceftazidime were mixed together and investigated aga

An Evolutionary Algorithm for Improving the Quantity and Quality of the Detected Complexes from Protein Interaction Networks

One of the recent significant but challenging research studies in computational biology and bioinformatics is to unveil protein complexes from protein-protein interaction networks (PPINs). However, the development of a reliable algorithm to detect more complexes with high quality is still ongoing in many studies. The main contribution of this paper is to improve the effectiveness of the well-known modularity density ( ) model when used as a single objective optimization function in the framework of the canonical evolutionary algorithm (EA). To this end, the design of the EA is modified with a gene ontology-based mutation operator, where the aim is to make a positive collaboration between the modularity density model and the proposed

The effectiveness of change and transformation of formal displacement in the internal space (historical passenger stations as a model)

Intellectual and material displacement is one of the design strategies through many mechanisms and means, and depends on the idea of changing the shape within the internal spaces at times and has concepts related to the transformation at other times. And represented by the boxes for travelers, the research problem emerged through the following question: (What is the effectiveness of displacement in the formal structures in the interior design of historical sites), and the aim of the study is to reveal the reality of the use of historical internal spaces and to determine the formal displacement that occurs as a result of change and transformation, and it included two topics, the first topic Transformation and the effectiveness of formal d

The Constitutional and Legal Basis of National Human Rights Institutions in Iraq and their Compatibility with International Standards

The issue of human rights has become an international obligation of States, and the mere recognition of these rights by States, no matter how clear and precise, does not constitute a guarantee in itself. The state shall assume its status to respect human rights and fundamental freedoms. The national protection mechanisms are diverse. They are either constitutional, judicial or political. Human rights in Iraq, as each institution or body to be able to exercise its powers, must be based on a legislative basis, whether legal or constitutional basis, In order to achieve its goal of promoting and protecting human rights.

Experimental Study on Double-Pass Solar Air Heater with and without using Phase Change Material

In this paper, an experimental study was conducted to enhance the thermal performance of a double-pass solar air heater (SAH) using phase change material (PCM) for thermal storage at climatic conditions of Baghdad city - Iraq. The double-pass solar air heater integrated with thermal storage system was manufactured and tested to ensure that the air heating reserved after the absence of the sun. The rectangular cavity filled with paraffin wax was used as a latent heat storage and incorporated into the lower channel of solar air heater. Experiments were carried out to evaluate the charging and discharging characteristics of two similar designed solar air collectors with and without using phase change material at a constant

Accuracy and safety of CT guided transthoracic needle biopsy

Background:Image guided transthoracic needle biopsy (TTNB) has great diagnostic value for the definitive characterization of lung lesions and is an established primary procedure to diagnose pulmonary nodules. It is traditionally performed as an outpatient procedure. It is safe, accurate, sensitive, and can obviate surgical procedure.
Objective: to assess the accuracy and safety of CT-guided TTNB in Baghdad Teaching Hospital 
Patients & Methods: From December 2009 to September 2011, we conducted a prospective study of 43 consecutive outpatient and inpatient lung biopsies. An informed consent was obtained from the patients. No sedation is required. All biopsies were performed using CT guidance withou

Study the Effect of Using Microwave Radiation and H-Donors on Improving Heavy Oil

The present research has investigated the effect of microwave energy on improving the flow properties of heavy crude oil. The fragmentation of crude oil molecules was carried out with and without using 1 and 10 wt. % concentration of various types of H-donors like tetralin, cyclohexane, and naphtha.  Microwave power of 320, 385, and 540 W and radiation time 1-9 min, and temperature were studied. The kinematic viscosity and asphaltene content were measured for evaluation the improving of heavy crude oil.

   Results show that viscosity of crude oil decreased with increase H-donor concentration, a maximum percentage of viscosity reduction was10.63 % for tetralin at 6 min radiation time, while 8.67%, and 7.34% for cycl

Improving the Moisture Damage Resistance of HMA by Using Ceramic Fiber and Hydrated Lime

The Moisture damage is considered as one of the main challenge for the experts in the field of asphalt pavement design. The aims of the present study is to modify moisture resistance of the asphalt concrete by utilizing ceramic fibers as a type of reinforcement incorporated with hydrated lime. For this purpose, a penetration grade of the asphalt cement (40-50) was utilized as a binder with an aggregate of the maximum nominal size of 12.5mm and mineral filler limestone dust. A series of specimens has been fabricated by utilizing 0.50, 1.0, 1.5, and 2.0 percentages of ceramic fibers. For each of these contents, another subsequent group of specimens with hydrated lime with 0.0, 1.0, 1.5, and 2.0 percentages were moulded. For the additi
