He asserts that tiny variation of her hand make &nbsp;the first trajectory different from the second one.</p> <p>Now let us ask what happened in Jurassic Park? Dr Malcolm attributes this unpredictability to chaos. He said that many times when he saw that the events of the film evolve in unpredictable way.&nbsp; He use his mathematics to grantee that the park will be out of the control of its manager. Of course he is correct, but is it truth that the Chaos is the cause of the chaos of Jurassic Park. Let us know what Chaos is and then answer this question.</p> Ali Hasan Abdul Khaleq, Eman S.

The speech for the purpose of authentication is commonly used. Recognition of the speaker is the method that can check and recognize the speaker. The scheme of speech recognition is distinct from the scheme of speaker recognition. Recognition of speakers is commonly used in sectors, hospitals, laboratories, etc. Its benefits are safer, easier to implement, more user-friendly. Speaker identification method is one of the most commonly used techniques for the region where safety is very crucial. This article presents an overview of various methods that can be used to recognize speakers’ systems, the feature extraction techniques such as Linear Predictive Coding (LPC), Linear Predictive Cepstral Coefficients (LPCC), Unique Mapped Real Transform (UMRT), Real Cepstral Coefficients (RCC), “Mel-frequency Cepstrum” (MFCC), in addition to &nbsp;various classification techniques such as “Gaussian mixture model (GMM)”, “Dynamic Time Warping (DTW)”, Support Vector Machine (SVM), Neural Network (NN), “Vector Quantization” (VQ). The primary purpose of is to explain the common speaker recognition methods. The obtained results are that, MFCC is chosen for high efficiency and low complexity. and GMM is helpful in classifying less memory and less planning and efficient test results.</p> Sahar Adil Kadhum, Ahmed Badri Muslim, Ali Yakoob Al-Sultan Copyright (c) 2020 Journal of University of Babylon Tue, 15 Dec 2020 00:00:00 +0000 Evaluation of Different Methods of Curing Bacterial Plasmids <p>Plasmids play an important role in the spread of antibiotic resistance among bacterial strains that pose a threat to global health. Traditional methods of curing plasmid rely on the development of bacterial strains under inappropriate conditions, such as high temperature or the addition of intruding agents that interfere with the structure of DNA synthesis during the replication of plasmids. Other methods rely on the phenomenon of plasmid compatibility based on the principle of competition between identical plasmids but require accurate knowledge of the mechanism of multiplying the target plasmid, in addition to the subsequent treatment of the interfering plasmid. With the advent of Crispras9, which simulates natural bacterial defense against plasmid and latex infiltrators, this technique has been used as an accurate tool for targeting places specializing in plasmid DNA. In this review, we will address the most important methods of removing and deleting plasmids from bacterial cells.</p> Dalal. M.R. Al-Shuailiyah, Zahraa M. AL-Taee , Raflaa S.H.

Furthermore, inverse force/source problem comes from splitting wave equation, which is unstable while adding noise under the right end boundary condition. Numerical algorithm is based on finite different method (FDM) combine with separation variable. L-curve method and min norm is applied to reach regularization parameter where zeroth order Tikhonov regularization is proposed. Figures in section 3 are shown how accurate this unusual condition working in the wave equation.&nbsp;</p> <p>&nbsp;</p> S.O.

COVID-19 is spread by droplets or direct contact and, in most cases, infects the respiratory tract leading to pneumonia and, in around 15% of cases, to acute respiratory distress syndrome (ARDS). Mortality in COVID-19 patients has also been linked to the existence of the virus-induced cytokine storm. Excessive pro-inflammatory cytokine production contributes to the aggravation of ARDS and significant damage to tissues, leading to multi-organ failure and death. The cytokine storm's pathogenesis is very complex. Much data suggests that the extreme worsening in several patients was directly linked to the cytokine storm in their bodies during the COVID-19 epidemic. This article discusses the cause of incidence and management methods of the inflammatory storm caused by the COVID-19 virus to offer useful clinical treatment advice without using drugs.</p> Rojan G.M.

About 80 percent of these cases are thought to be directly associated with the formation of aerosols during the lab. works with potentially infectious samples. Small liquid or solid particles of aerosols suspended in the air for a while or spread over a wide range of distances and then inhaled easily. However, they can be settled rapidly on surfaces such as skin and ventilation systems if the diameters of particles are higher than 5 microns. Effective steps should regularly be used to protect staff and the environment, or to reduce the extent of the aerosols production. Measures containing the aerosol are to be applied where physical containment at practice 2(P2) and above levels is needed for the research operation.</p> <p>In most cases the safely equipment’s and precautions must be available in all time in the lab. and comply with the required level of Biosafety for any type of the laboratory work (including the relevant biological agents, SARS-CoV-2 in this case). Staff who working with suspected or confirmed specimens of COVID-19 or of SARS-CoV-2 should be completely protected from such infectious materials. Good biosafety practices have been recognized to avoid or mitigate the spread of infection (i.e., SARS-CoV-2). Standard precautions expected to be already used by laboratories as stated in the general guidelines and they should follow standard laboratory practices. Practices related with these biosafety requirements must be proceed when dealing with samples/specimens from SARS-CoV-2. This involves microbiological as well as clinical laboratories conducting routine serum, blood, sputum (respiratory) and other sample diagnostic, analytical, or other research-related studies.</p> Zeena Hadi Obaid Alwan, Rafal Ahmed AL-Gelawi, Suad Ghali Kadhim Al-Ahmed Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Ventriculosubgaleal shunt versus External Ventricular Drain in the treatment of Acute Hydrocephalus in Adults <p>Hydrocephalus is caused by subarachnoid hemorrhage (SAH), intraventricular hemorrhage (IVH), Infection or by a tumor compressing the CSF passages is mostly temporary and can resolve with treatment. We have many methods to assure cerebrospinal fluid (CSF) diversion, no method is considered more preferable than others; so, to choose a method depends on the causes or other factors.</p> <p>Ventriculosubgaleal shunt (VSGS) is one of those temporary ways in which we can assure a simple and rapid CSF decompression method and not causing electrolytes or nutritional losses.</p> <p>To study the effectiveness of using VSGS compared to external Ventricular Drain (EVD) in adult hydrocephalus for temporary CSF conversion and to find out the results that help us avoid putting a permanent shunt, and last, to find the possibility of occurrence of complications.</p> <p><strong>&nbsp; </strong>A retrospective observational study.</p> <p><strong>Materials and Methods</strong>: The data were taken from Hospital Admission notes of fifty patients with acute hydrocephalus: 26 caused by IVH, 10 from ruptured aneurysm, 8 post-traumatic, and 6 were due to infection. In all the patients we did CSF conversion in Hospital Queen Elizabeth II, Sabah, Malaysia, from 2012 to 2015. The patients’ follow-up started from the date of surgery till the hydrocephalus is treated completely Parameters used are the dependency to the shunt and the occurrence of complications.</p> <p>&nbsp;&nbsp;Statistical Packages for the Social Sciences Version 22.0. Chi squared test, Fisher’s exact test.</p> <p><strong>Results</strong>: A total of 21 (42%) patients, EVD inserted and 29 (58%) VSGS inserted. Thirty-seven (74%) patients did not need a permanent shunt; 24 (64.8%) of them were from the VSGS group (P = 0.097). EVD patients developed more complications (44.1%) in comparison to VSGS (23.5%), with a statistically significant difference P = 0.026.</p> <p><strong>Conclusions</strong>: VSGS is a safe and a dependable way for adult hydrocephalus patient’s treatment, with the ability to continue the treatment for such patients in non-neurosurgical centers or even discharge the patient home, as compared to patients with EVDs. This method does not have a statistical difference to avoid putting a ventriculoperitoneal shunt, VSGS has a significant less complications than EVD.</p> Salah Mahdi Jaddoa, Husham Majeed Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Applications of Silver Nanoparticles as Antibiotics for Pathogenic Organisms: Bacteria, Fungi ,Viruses and Algae <p>Silver nanoparticles are used in the medical and engineering fields and are still of interest to scientists, possibly due to their small size compared to their efficiency. Previous research has demonstrated the efficacy of silver nanoparticles in inhibiting microbes as they are used as reducing agents. Silver nanoparticles are manufactured in a variety of chemical or physical ways that may have environmental hazards due to their potential toxicity, or they are manufactured in biological, environmentally friendly and non-toxic ways.</p> <p>In this review, we first present the properties of nanoparticles and their synthesis methods and then discuss their role as inhibitors of bacteria, fungi, viruses and algae.</p> Huda Abbas Mohammed, Lubna Abdul Muttalib Al-Shalah Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Jacobi Weighted Moduli of Smoothness for Approximation by Neural Networks Application <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;Moduli of smoothness are intended for mathematicians working in approximation theory, numerical analysis and real analysis.

Zubair Formations was deposited within Mesopotamian Zone during the Barremain stage which belong to the Early Cretaceous epoch.</p> <p>The major component of Zubair succession is sandstone which classify as quartz arenite (also known as orthoquartzite) has about 92% or more quartz grains. While a rock having &gt;25% lithic fragments and subordinate feldspars are lithic arenites; those with clay content &gt;25% and subordinate lithics is a gray wacke</p> <p>Five major lithofacies within two groups of rock dominance are recognized in this succession as follow:- Quartz arenite well sorted-subrounded Lithofacies, Quartz arenite poorly sorted sub-angular Lithofacies and graywacke poorly sorted Lithofacies within the sand dominated rock; and Sandy claystone and Shale Lithofacies within clay dominated rocks. Three facies associations are distinguished in studied succession, they are: delta plain, delta front and back-shore. The microfacies analysis and reconstructed the paleoenvironments for the Barremain basin in the studied area has contributed to determine three stages matching with the observable units.</p> <p>&nbsp;Main composed of the lower unit is shale with thin beds and lenses of sandstone to divided this unit into two parts, the upper most is sandstone and the lower part is consisting of shale in the south part of studied area. This sequence is interpreted to form in a delta plain deposits was common in the north and south part of the studied area (WQ-13, WQ-1 and WQ-356), while the middle part of this area (WQ-60 and WQ-15) was closed to shore face environment. The middle unit is the thickest and characterized by alternative of shale and sand beds as Three laterally heterogeneous cycles. These three-cycle appeared clearly in the southern part of studied area, while to the north became two cycle. In the central of studied area the middle part is represented by one cycle of quartz arenite well sorted-subrounded lithofacies as a delta front and shoreface association facies. The delta plain is common association in the WQ-13 and WQ-148 as a successive of lithofacies 3, 4 and 5, while this association is alternative with back shore association to the north direction (WQ-15, 1 and 356). Upper unit is composed of sandstone as quartz arenite well sorted-subrounded lithofacies. This refer to deposition in the delta front and shore face to mark the sea level rise in all studied well except WQ-60, which represent the delta plain association facies. This cycle was marked the end of Zubair deposition during the transgression stage.</p> Rusul Hakim Ali , Aiad Ali Hussien Al-Zaidy Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 The Biological and Medical Applications of Laser Light Abstract <p>The process of rapidly developing laser technology with the presence of the latest laser devices, which are constantly being introduced has become important in a variety of biological and medical fields.

This bacterium produces many virulence factors that participate in the mechanics of injury. The battle between human host and bacterial pathogen is extremely complex. Each side tries to outpace the other in the race for survival. Particularly in the innate immune system in humans, the complementary immune system acts as the first line of defense against invading pathogens during the course of evolution, however, the pathogen has developed multiple strategies to counter the host complement system and colonization, for survival and sustainability within the host. One of these pathogens is Streptococcus (pneumococcus), which are Gram-positive bacterial pathogens that often coexist in the human respiratory system. Depending on the host's sensitivity, pneumococcus can transform into an infectious agent that spreads within the human host and causes diseases ranging from mild to severe and potentially life-threatening diseases. This transition from the symbiont to the infectious agent is a very complex process and an understanding of this mechanism is essential in controlling pneumococcal disease. Using its complex arsenal of weapons such as surface adhesions as well as pneumococcal recruitment recruit the host's immune system. This review discusses the biological activity of several pneumococcal virulence agents and describes C1q, the first subunit of the classic complement pathway, and its role in antimicrobial reactions, as pneumococcus exploits C1q as a molecular bridge that facilitates the attachment of this bacterium to the cell surfaces of the host.</p> Hawraa Mohammed Ridha , Zahraa M.

It has become important to protect this information and find the best and most secure way to transfer and it to protect it from piracy attempts and common attacks on the Internet. In this paper, the encryption and steganography techniques are used to secure a transmitted through unsecure network. In this paper, we proposed a method for encryption images using second-order equations, then the encrypted image is embedded in the vide. The image is embedded according to the equations rather than embedding it sequentially in order to increase the security layer. The experimental results suggest that the approach proposed is achieves a high embedding ability. In addition, encryption and non-sequential selection of frames and locations for bit hiding increases the safety and robustness of the proposed system when compared to other methods of hiding information.</p> Hawra’a Razzak Radhi, Majid Jabbar Jawad Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Biostratigraphy of Qamchuqa Formation in Jambur Oil Field in Kirkuk Area <p>The Qamchuqa Formation has been studied in three wells ( Ja-15, Ja-20, Ja-22) within Jambur oil field, North East of Iraq .

A number of monotectic Al-rich binary alloys having limited solubility in the solid state have been pointed up as desirable for many industrial applications, e.g., self-lubricated bearings, electronic materials, superconductors and optical components. Monotectic alloys undergo an invariant reaction at the monotectic temperature, in which a liquid phase, L<sub>1</sub>, is decomposed into a solid phase, S<sub>1</sub>, and a liquid phase, L<sub>2</sub>. During cooling, the minority liquid phase forms discontinuous and isolate droplets or fibers within the Al-matrix. The competition between the growth of the minority phase and the rate of displacement of the solidification interface will determine if the prevalent morphology will be formed by droplets or fibers. Chill-block melt spinning technique was used to examine the possibility of casting Al-Bi monotectic alloys with possible homogeneous microstructure. The resulting microstructure was analysed by scanning electron microscopy and X-ray diffraction. The electrical resistivity, thermal parameters, internal friction, thermal diffusivity, elastic moduli and hardness of the melt-spun ribbons have been investigated as a function of composition. The results reveal that several combinations of strength, hardness, enthalpy, entropy change, resistivity and internal friction can be generated from the alloys to meet the needs of antifriction applications.</p> Sanaa Razzaq Abbas, Mohammed S.

In the other hand, since secret communications and development of multimedia contents, stenography of the techniques&nbsp; reflect important roles. In based are reflected stegnography system, the quality of stego image and the capacity of the cover image are important side of the image, evaluate performance and comparison of&nbsp; techniques are depending on these parameters in steganography system. There are existing embedding techniques that aim to protect information, and a higher bit embedding rate is an important challenge in designing a steganographic system. &nbsp;This paper highlights a literature review of the classification spatial domain (beads on pixel value) approach&nbsp; of image steganography; include, (i) LSB steganography, (ii) PVD based steganography, (iii)GLM based steganography, (iv) PPM based steganography. The goal of this paper is to supply a comprehensive summary of&nbsp; existing works in terms of ideals, and to highlight the strong and weak points of current&nbsp; techniques.</p> Sura I.

This study aims to compare the efficacy and safety of pizotifen with topiramate; one of the most-widely used drugs in migraine prevention. Methods: This was a single blind, randomized, parallel-group study. After a 4-week baseline evaluation, patients with episodic migraine were randomly assigned to get either to piramate or pizotifen for a period of 12 weeks. Patients were asked to fill a headache diary through the study. Headache characteristics and the possible side effects were evaluated throughout and at the end of trial. Results: Sixty patients aged 20 to 49 were recruited to the study. With both drugs, the frequency, intensity and duration of headaches were significantly reduced (p &lt; 0.05). Except for headache duration, pizotifen was significantly superior to &nbsp;topiramate in the headache parameters assessed. Total reported side effects were initially higher inpatients who received pizotifen (37 vs. 22; P= 0.038); however, persistent side effects were lower for pizotifen (6 vs. 10; P= 0.22).Conclusions: The results of this study suggest that pizotifen is a safe and effective drug in migraine prevention.</p> Mazin M Mohsin Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Study Molding of Vortex state in the Atmosphere <p>The Earth's atmosphere as a whole has a very complex system of movements that changes over time. The main features of these movements are repeated from year to year and are well displayed on average and climatic maps, which are the starting point for conclusions about the general circulation of the atmosphere. So it is known that the movement of the atmosphere has a vortex character. There are basic states of three-dimensional vortex motion, in which low pressure convergence leads to an upward motion, and high pressure divergence leads to a downward flow in a vortex motion (tornado). These states of the three -dimensional velocity field can be described using the expansion of the convection velocity in terms of stream and potential functions, which describe the spiral structures of this movement. In this paper, simple partial differential equations are introduced that satisfy the ground state of three-dimensional vortex motion. It is also shown that when Re → ∞, the vortex motion degenerates into geostrophic wind, and the corresponding state of vortex motion is replaced by the geostrophic state.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> Qasim S.

Behaviors can include lack of activity, physical activity, drug use, dietary patterns and other types of exposure. Additional contributing factors include environment of physical activity, skills, food, food marketing, and promotion.</p> <p>Obesity is dangerous because it linked to worse outcomes for mental health and lower quality of life. In the United States and around the world, obesity also linked to the leading causes of death, including diabetes, heart disease stroke, and some types of cancer. Obesity is a disorder of excess fats in the body. It is a chronic condition with a complex interaction between environmental and genetic factors. It related to high blood cholesterol levels, high blood pressure, fatty acid levels, insulin hypersensitivity and the accumulation of excess fat mass. More than one billion adults are overweight and 300 million of them at least are obese. More than a billion adults are overweight and at least 300 million are obese. It determined by the BMI and further estimated by the percentage of body fat and total body fat.&nbsp; Obesity is a danger for many secondary conditions such as cardiovascular disorders, retinopathy, neuropathy, pathological insulin resistance and cancer. Multiple factors that alter the incidence of obesity involve sex, age, and smoking, levels of growth hormone and metabolism of skeletal muscle.</p> Shaima Ahmed Rahim, Manar Mohammad Hasan AL-Murshidi Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 A Anatomical Study of Fruits for Some Genera of Fabaceae Family Grown in Makhoul Mountain–Salah Al-Din – Iraq <p>The fruits of six species belonging to four genera of the Fabaceae family were studied. Wild species of dicotyledons that grow in the study area and in the foothills of Makhoul Mountain in Salah al-Din governorate were studied.&nbsp; The fruiting layer between them, and the shape of the cells that made up each layer, all fruits consisted of three layers, the exocarp, the mesocarp, and the endocarp.&nbsp; The thickness of each layer was different in all species. It was found that the fruiting envelope is thicker in the type Medicago polymorpha L, as the average thickness of the coat reaches (342) micrometers, and the thickness of (146.9) micrometers was recorded in the type M. monspeliaca.&nbsp; As for the shapes of cells and their types, remarkable variations were recorded, as they had several shapes (oval, spherical, elliptical, semi-oval, elongated) and this makes them of taxonomic significance even between the phenotypically close types, which confirmed the current study, in addition to&nbsp; Lack of anatomical studies of the fruits of wild species in Iraq.</p> Mohammed Adnan Hashem Al-Blesh, Ibrahim Jassim Sultan Al-Dulaimi Copyright (c) 2020 Journal of University of Babylon Thu, 31 Dec 2020 00:00:00 +0000 Some Generalized Difference Cesàro Double Sequence Space of Fuzzy Real Number Defined by Double Orlicz Function <p>In this paper we introduce some generalized difference Cesàro double sequence space of fuzzy real number by using double orlicz function . and we study their different properties like completeness , solidity, symmwtricity etc. .
