    The present study aims to convert obsidian rocks into spongy gravel for the use in the production of lightweight and heat insulating concrete. The rocks were burned at 960°C to achieve maximum swelling of the samples, then broken into gravel and sand sizes. For comparison purposes, two other types of aggregates were used, namely pumice and basalt. The main physical tests, such as specific gravity, bulk density, porosity, and water absorption were performed. For testing the resistance of samples to alkalinity, KOH and Na OH solutions were used. The results showed that the obsidian sample gave the best specifications, where its specific gravity was 0.33, while the values were 1.1 for pumice and 2.7 for basalt, with the

Background & Objective: Breast cancer (BC) is the most prevalent disease among women around the world, considered the world's leading cause of death (15% of the total cancer deaths) in women in 2018. β-catenin is a multifunctional protein located in the cytoplasm and/or nucleus of the cell. Several studies suggested that β-catenin expression plays a critical role in cancer invasion and metastasis. This research sought to examine β-catenin expression in breast cancer and its associations with clinico-pathological features (such as histopathological types, grade, and invasion depth of tumor as well as lymph node involvement) and breast cancer patient survival. Methods:

Two hundred urine samples were collected from patients infected with acute and
chronic urinary tract infection, 85 bacterial isolate were isolated from these samples
and were diagnosed using biochemical tests and kit API test, most of them identified
E.coli (23.5%) K.pneumoniae rate (17.6%). Isolates were selected E.coli and
K.pneumoniae according to their isolation rate from urinary tract infection cases and
their antibiotic resistance. The inhibition effect of the purified catechin from the
green tea was studied when the isolates were grown in the following concentrations
(25, 50,75, 100) mg/ml. The concentration of 100 mg/ml showed a high action
against the two species. The combination effect of

Anti-Toxoplasma gondii seropositive status among obese and diabetic patients has recently attracted substantial attention. The objective of this study was to assess the seropositive rate of T. gondii and its relation to high body mass index (BMI), diabetes, and metabolic syndrome among participants (n=100) who attended Al-Kadhimiya Teaching Hospital, Baghdad-Iraq. An observational analytical study was conducted from October 2019 to March 2020. Participants were divided into three groups based on their BMI; obese (n=38), overweight (n=32) and normal (n=30). In addition, they were divided into diabetic (n=45) and non-diabetic (n=55) based on clinical examination, laboratory examination, and medical interview. Another clas

The current investigation aimed to test the alterations of the levels of obestatin hormone, lipid profile and cardiac function markers in relation to hyperglycemia in patients with non-insulin diabetes mellitus. The study included 118 diabetic subjects (56 males, 62 females) and 60 healthy non-diabetic subjects (30 males, 30 females). Diabetic and healthy subjects were age-matched. Serum levels of obestatin, lipid profile markers including total cholesterol (STC), triglycerides (STG), low and high density lipoproteins (LDL-C and HDL-C), as well as cardiac function markers including, creatine kinase and lactate dehydrogenase enzymes were determined in all subjects. The findings revealed a remarkable decrease in the level of serum obestati

Writing with Arabic characters is a very sensitive operation because some characters are vertically nested and written in multiple ways. The infinite variety of font styles and sizes poses many challenges when designing Arabic recognition systems. In this article, we used deep learning to build an Arabic recognition system that could recognize dotted letters. Our dataset contains 3000 color images for ten letters ( م ,و ,ل ,ع , ,ص ,س,ح ,و ,ط ,ر د ). The training stage was achieved through 2250 images (10 classes) of this data, and 750 images were used for the validation stage. The classification accuracy of our proposed model is 98.67 percent. Experimental results show that Arabic font styles (Diwani, Hacent Dalal, Times New R

     Epilepsy is a central nervous system disease which is characterized by a recurrent seizure that distinguishes it from other similar diseases. Epilepsy may occur due to defects in genes that encode some receptors in the brain. For this reason, this study aimed to understand the association between Synapsin-2 (SYN2) gene and susceptibility to epilepsy. Blood samples were collected from 40 volunteers, including 30 patients suffering epilepsy with an age range of 26-49 years old and 10 healthy individuals with an age range of 25-53 years old. The study sample involved 16 males and 14 females with epilepsy along with 6 males and 4 females healthy subjects.  DNA was isolated from the volunteers for PCR-RF

Apple vinegar has many uses that include burn and wound healing and as an antimicrobial agent against different microorganisms, but not as a solvent. Therefore, this study aimed to use commercial apple vinegar as solvent to the plants of  roselle (Hibiscus sabdariffa), green tea (Camellia sinensis), and clove (Syzygium aromaticum). The effects of apple-vinegar extracts of these plants were compared with those of aqueous and ethanolic extracts against biofilm formation by Candida genus. Clove vinegar extract demonstrated antibiofilm activity against C. albicans, alone (2.4907± 0.382) or in combination with the antifungal agents fluconazole (1.689±0.33), nystati

The main goal of this work, is to study new classes of bornological semi group with respect to S-bounded maps, S*-bounded maps and S**-bounded maps. This manuscript would be useful to give the theoritical solution for problems in bounded and limatation by restrict the condition of boundedness.

The main objectives of the present research are of two goals; first, to define and
locale the main cover types (components) of AL-Hawizeh Marshes, and second, to
track and detect the changes encountered in these cover types (components) during
the last three decades time episodes To fulfill these goals, LANDSAT and MODIS
images were applied. The LANDSAT images (MSS-1973, TM-1990 and ETM+
2002) were used to determine the Marshlands cover types before, during and after
the Marsh destruction (marshes dehydrations). One MODIS image was selected to
cover the main changes that have been happened in 2010. Programming; Supervised
classifications (minimum distance classification) were applied for monitoring

Digital tampering identification, which detects picture modification, is a significant area of image analysis studies. This area has grown with time with exceptional precision employing machine learning and deep learning-based strategies during the last five years. Synthesis and reinforcement-based learning techniques must now evolve to keep with the research. However, before doing any experimentation, a scientist must first comprehend the current state of the art in that domain. Diverse paths, associated outcomes, and analysis lay the groundwork for successful experimentation and superior results. Before starting with experiments, universal image forensics approaches must be thoroughly researched. As a result, this review of various met

Several heterocyclic compounds bearing an imidazo(1,2a)pyridine moiety have been synthesized in this work, including triazole, thiazol, and thiazolone. This was done by condensation of 2-aminopyridine with 2-aminopyridine with 4-bromophencyl bromide or 4-phenylphencyl bromide to produce 2-substituted phenyl imidazo(1,2a)pyridine compounds 1 and 2. The Vilsmeier-Haak reaction was used to create the aldehyde group at position 3 of the 2-substituted phenyl imidazo(1,2a)pyridine ring (3 and 4). The reaction of compounds 3 and 4 with thiosemicarbazide afforded thiosemicarbazone derivatives 5 and 6 in 66 and 70% yields, respectively. These derivatives (5 and 6) were then subjected to three different cyclization reactions to obtain 1,3-thiazolo

Buddy system algorithm is dynamic memory control which is usually embedded in
the memory management unit, which is a part of the most widely use modern operating
systems. Dynamic memory management is an important and essential part of computer
systems design. Efficient memory allocation, garbage collection and compaction are
becoming increasingly more critical in parallel, distributed and real-time applications
using object-oriented languages like C++ and Java. In this paper we present a technique
that uses a Binary tree for the list of available memory blocks and show how this method
can manage memory more efficiently and facilitate easy implementation of well known
