Determination of Magnitudes and Orientation of the Paleostress of Bekhme Structure in Shaqlawa area, Northerneastern Iraq
Authors: AL- Hachem Atheer E. K. , Hassan Shatha
Published: May 2021

This study presents the determination of the paleostress magnitudes and orientation of Bekhme Structure in Shaqlawa area, northeastern Iraq. Paleostress analysis of slip-fault measurements is performed using Right dihedral, Lisle diagram, and Mohr Circles methods. Depending on Mohr Circles, Bott law, and vertical thickness, the magnitudes of the paleostress at the time of the tectonic activity were determined. Firstly, Georient Software was used to estimate the orientation of the paleostresses (σ1, σ2, and σ3). Secondly, using the rupture –friction law, taking into account the depth of the overburden and the vertical stress (σv),the magnitudes of the paleostresses were calculated (σ1=4500 bars, σ2=1900 bars and σ3=700 bars).  The high magnitudes of the principal stress axes may be attributed to the active tectonic events which led to the deformation of the area during the Cretaceous and Tertiary periods. The study area shows that the poles of the measured faults lie in the reactivated area of Mohr circles. This indicates the instability of the study area.  The study area is estimated to have high importance, due to the possibility of the existence of deposited hydrocarbons. Fold- Thrust belt marks the deformation fronts of the major orogeny that forms from the collision of the Arabian Plate with the Turkish and Iranian Plates.
The Use of Parametric and Nonparametric Methods to Study the Effects of Smoking on High-Density Lipoprotein Cholesterol
Authors: Ahmed Layla A.
Published: May 2021

Analysis of variance (ANOVA) is one of the most widely used methods in statistics to analyze the behavior of one variable compared to another. The data were collected from a sample size of 65 adult males who were nonsmokers, light smokers, or heavy smokers. The aim of this study is to analyze the effects of cigarette smoking on high-density lipoprotein cholesterol (HDL-C) level and determine whether smoking causes a reduction  in this level, by using the completely randomized design (CRD) and Kruskal- Wallis method. The results showed that the assumptions of the one- way ANOVA are not satisfied, while, after transforming original data by using log transformation, they are satisfied. From the results, a significantly decreased level of HDL-C in smokers as compared to non-smokers is indicated.

A study on Soft Pre-Open Sets using γ Operation
Authors: Jamil Jamil Mahmoud
Published: May 2021

The concept of strong soft  pre-open set was initiated by Biswas and Parsanann.We utilize this notion to study several characterizations and properties of this set. We investigate the relationships between this set and other types of soft open sets. Moreover, the properties of the strong soft  pre-interior and closure are discussed. Furthermore, we define a new concept by using strong soft  pre-closed that we denote as locally strong soft  pre-closed, in which several results are obtained. We establish a new type of soft pre-open set, namely soft  pre-open. Also, we continue to study pre-  soft open set and discuss the relationships among all these sets. Some counter examples are given to show some relationships obtained in this work.

Authors: Abdul-Kareem Shaymaa Amer , Abdulkareem Ahmed Amer , Abdul-Kareem Yusra Amer
Published: May 2021

The concept of closed quasi principally injective acts over monoids is introduced ,which signifies a generalization for the quasi principally injective as well as for the closed quasi injective acts. Characterization of this concept is intended to show the behavior of a closed quasi principally injective property. At the same time, some properties of closed quasi principally injective acts are examined in terms of their endomorphism monoid. Also, the characterization of a closed self-principally injective monoid is given in terms of its annihilator. The relationship between the following concepts is also studied; closed quasi principally injective acts over monoids, Hopfian, co Hopfian, and directly finite property. Ultimately, based on the results obtained, the conditions on subacts to inherit a closed quasi principally injective property were shown. Part of this paper was dedicated to studying the relationship between the classes of closed quasi principally injective acts with some generalizations of injectivity. Conclusions and future remarks of this work are given.

Authors: Murad Mohammed Ali , Abdulhadi Ahmed M.
Published: May 2021

The peristaltic transport of power-law fluid in an elastic tapered tube with variable cross-section induced by dilating peristaltic wave is studied. The exact solution of the expression for axial velocity, radial velocity, stream function, local shear stress, volume of flow rate and pressure gradient are obtained under the assumption of long wavelength and low Reynolds number. The effects of all parameters that appear in the problem are analyzed through graphs. The results showed that the flux is sinusoidal in nature and it is an increasing function with the increase of  whereas it is a decreasing function with the increase of . An opposite behavior for shear strain is noticed compared to pressure gradient.  Finally, trapping phenomenon is presented to explain the physical behavior of various parameters. It is noted that the size of the trapping bolus increases with increasing  whereas it decreases as  increases. MATHEMATICA software is used to plot all figures.

Authors: Hashim Asaad Noori , Al-Khalidy Roaa Razaq
Published: May 2021

Iris recognition occupies an important rank among the biometric types of approaches as a result of its accuracy and efficiency. The aim of this paper is to suggest a developed system for iris identification based on the fusion of scale invariant feature transforms (SIFT) along with local binary patterns of features extraction. Several steps have been applied. Firstly, any image type was converted to  grayscale. Secondly, localization of the iris was achieved using circular Hough transform. Thirdly, the normalization to convert the polar value to Cartesian using Daugman’s rubber sheet models, followed by histogram equalization to enhance the iris region. Finally, the features were extracted by utilizing the scale invariant feature transformation and local binary pattern. Some sigma and threshold values were used for feature extraction, which achieved the highest rate of recognition. The programming was implemented by using MATLAB 2013. The matching was performed by applying the city block distance. The iris recognition system was built with the use of iris images for 30 individuals in the CASIA v4. 0 database. Every individual has 20 captures for left and right, with a total of 600 pictures. The main findings showed that the values of recognition rates in the proposed system are 98.67% for left eyes and 96.66% for right eyes, among thirty subjects.

Published: May 2021

This paper aimed to determine the Optimal Reliable Frequency (ORF) that can maintain certain connection link between different transmitter/receiver stations laid over the Iraqi territory. Three different transmitting sites were chosen as tested stations located in the northern, central, and southern regions of Iraq. These sites are Mosul, Baghdad, and Basra, respectively. In this study, the years 2009 and 2014, which represent the minimum and maximum years of solar cycle 24, were chosen to examine the effect of low and high solar activity on the determined ORF. The datasets of the Best Usable Frequency (BUF) were calculated using the ASAPS international communication model. An analytical study was made on the generated BUF parameter dataset of the annual time for the adopted years. Also, an analytical simulation was made for the suggested ORF parameter depending on the BUF parameter datasets. The results of this simulation showed that the suggested ORF parameter can be represented by polynomial equation of different orders. The suggested formula was determined depending on different tested parameters (path length, bearing, time (day) and BUF values). For this purpose, a certain program was built using a visual basic programing language (VB6). The suggested ORF parameter was investigated for the annual time for the three sites of the years 2009 and 2014.

Published: May 2021

Background: In recent years consumers, due to the growing interest for functional foods, have put particularly attention on products enriched with probiotic lactic acid bacteria for their ability to give human benefit by their assumption. Microorganisms to be considered as probiotic should be able to survive to gastrointestinal juices and colonize the intestinal tract to provide benefits to human health. The aim of the study consisted of the in vitro investigation of novel LAB strains, isolated during cheesemaking and ripening of Caciocavallo cheese, and on their probiotic potential for food application. Methods: In order to select potential probiotic bacteria, LAB isolates were preliminarily screened for their survival to simulated gastro-intestinal transitand assayed for other activities of probiotic and functional interest. Thanks to promising attitude as potential probiotics, four strains were tested to evaluate their adhesion ability on Caco-2 cell lines used as intestinal cell model. Microbiological data were analysed by one-way analysis of variance (ANOVA). Comparisons of means were carried out using post-hoc Tukey’s test. For vitro adhesion experiments, statistical significance was evaluated by Kruskal-Wallis test for equal medians. Results: Twenty-five LAB, presumptively identified as Lactobacillus spp., were isolated from cheese during 60 days of ripening and screened for their survival to simulated gastrointestinal transit. Sixteen isolates that showed a survival rate ≥85% were identifiedas 10 different profiles of Lb. paracasei subsp. paracasei. The 10 strains tolerated high concentration of bile salts by Minimal Inhibitory Concentration and growth rate assays and showed susceptibility or moderate susceptibility against antibiotics of human and veterinary importance, except for the resistanceto the class of aminoglycoside antibiotics. Eight out 10 strains showed in vitro cholesterol-lowering ability, whereas all strains showed antioxidant activity of their cell-free supernatants. Moreover, the four strains with highest survival to simulated gastrointestinal transit showed the ability to adhere to Caco-2 cells. Conclusion: The results suggest that some strains may be effective probiotics to be use as tool to design probiotic dairy products after confirmation probiotic activities in further in vivo studies. Findings of the present study suggest that four strains showed good or strong adherent ability on Caco-2 cell monolayer, that is one of prerequisite that probiotic bacteria must have to perform their functional properties. Keywords: adhesion, antioxidant activity, bile salts, cholesterol assimilation, dairy products, gastrointestinal resistance, probiotic lactobacilli.
Six Meta-analyses on Treatments for Femoroacetabular Impingement Syndrome in a Year and Readers Are None the Wiser: Methods Advice for Researchers Planning Meta-analysis of Data From Fewer Than 5 Trials

Published: May 2021

Synopsis

In 2020, 6 meta-analyses comparing arthroscopic hip surgery to physical therapy were published. All included the same 3 randomized controlled trials, and none used methods suitable for the analysis of fewer than 5 studies. When there are fewer than 5 studies and heterogeneity, a random-effects model with the Hartung-Knapp-Sidik-Jonkman adjustment for a maximally conservative estimate should be employed; if reliable prior information is available, a Bayesian random-effects meta-analysis should be employed. Our re-analysis, which employed the appropriate model, found that there is currently insufficient evidence to conclude that surgery is superior to physical therapy for femoroacetabular impingement (FAI) syndrome. Further randomized controlled trials are required to resolve the clinical question of what the best treatment approach is for FAI syndrome. We provide readers with tools to conduct appropriate meta-analysis of fewer than 5 trials. J Orthop Sports Phys Ther 2021;51(5):201–203. doi:10.2519/jospt.2021.0107

[ID] Permasalahan banjir merupakan permasalahan pengelolaan air yang sering terjadi di Indonesia. Untuk mengatasi permasalahan tersebut dibuat sebuah struktur yaitu waduk yang berfungsi sebagai pengendali banjir. Namun seiring waktu tampungan waduk akan semakin menurun akibat adanya akumulasi sedimen yang terbawa oleh air sungai yang masuk ke dalam waduk dan mengendap. Sehingga diperlukan evaluasi kinerja tampungan waduk tersebut, Permasalahan ini juga dialami oleh Waduk Selorejo yang terletak di Kabupaten Malang. Untuk melakukan evaluasi kinerja tampungan waduk digunakan bantuan perangkat lunak HEC-HMS yang dapat mensimulasikan debit banjir yang masuk beserta elevasi tampungan waduk. Berdasarkan hasil analisis tampungan Waduk Selorejo mampu untuk mengendalikan banjir periode ulang desain awal nya yaitu periode ulang 1000 tahun. Selain itu Waduk Selorejo juga mampu menampung debit banjir Probable Maximum Flood (PMF) apabila muka air awal waduk diturunkan sampai elevasi +605 m.

[EN] Flood problem is a water management problem that often occurs in Indonesia. To overcome this problem, a structure is created, namely DAM that functions as a flood controller. However, over time the reservoir storage will decrease due to the accumulation of sediment carried by river water that enters the reservoir. So it is necessary to evaluate the performance of the Rervoir storage. This problem is also experienced by the Selorejo DAM which is located in Malang Regency. To evaluate the performance of the reservoir storage, the help of HEC-HMS software is used which can simulate the incoming flood discharge along with the elevation of the reservoir. Based on the analysis, the Selorejo DAM is able to control the flood of  its initial design period which is the 1000-year return period. In addition, the Selorejo Reservoir is also able to accommodate the Probable Maximum Flood (PMF) flood discharge if the initial water level of the reservoir is lowered to an elevation of +605 m.

A comprehensive study of digitalization is of fundamental importance for the development of the national economic system – an assessment of the features of the development of the digital economy in the regions of the Russian Federation. In order to identify the competitiveness of Russian Federation in terms of digitalization, the authors performed international comparisons on the values of various digitalization indices. In order to study the level of development of the digital economy in the regional context, the authors formed a system of indicators. The article highlights groups of indicators that characterize the readiness of the population, organizations, and public administration. The paper gives the characteristics of the fluctuation of the values of indicators that characterize the level of development of the digital economy in the subjects. According to the results of comparing the indicators that characterize the readiness for the digital economy in the federal districts in 2018 with the average Russian value, the authors identified the leading and lagging federal districts. The study performed the ranking of federal districts according to the values of indicators characterizing the development of the digital economy, as a result of which, received conclusions regarding the uniformity of the development of the considered components of the digital economy. The paper systematizes recommendations for the implementation of multidimensional groupings of regions both in individual areas and in the entire set of indicators proposed for analysis. Based on the results of grouping by the method of cluster analysis, the authors formulate key conclusions for groups of subjects of the Russian Federation.

The analysis made it possible to see not only the differentiation of the subjects of Russian Federation in terms of the level of development of the digital economy, but also the “weak points” of digitalization in different regions. The results obtained in the study can be useful for statisticians and economists when conducting research on the degree of informatization of the population and the economy both in the country as a whole and in its territories.

The article provides a brief overview of the emergence of the legal market of online cinemas in Russia. The paper reveals that the Governments of many countries have a national policy that is aimed at maintaining internal programming on traditional video platforms. Such policies range from licensing, which requires serving the “public interest” and defines rules for the distribution of certain types of content produced domestically, to requiring content distributors to contribute to the financing of the production of domestic content. The authors investigate that during the implementation of these rules, the Russian government decided on the allocation of limited resources. There was also regulation on whether platforms can solely decide what content to offer their users, or whether viewers should also participate directly. The study concludes that the transition from traditional platforms to online distribution can reduce the effectiveness of existing regulatory regimes and deprive traditional platforms of audience and revenue.

The world and Russian experiences of using the Internet prove that today modern information and telecommunications technologies can contain real threats to the violation of fundamental rights and freedoms of citizens, as well as to question the security of society and the state. The only exceptions are progressive or innovative areas related to the provision of new services and the expansion of opportunities for socio-economic development.

As a result of the study, the paper identified four problems of Russian film distribution on digital platforms. The authors chose piracy as the first problem of online cinemas. Pirate sites not only illegally copy content from online movie theaters, but they also create copies of their own services to transfer their servers to another platform in case of blocking. The second problem was highlighted by the requirement for foreign owners. The third problem was highlighted by the high cost of online movie theater subscriptions. The authors consider the fourth problem the lack of financial support from the state.

The area of research presented in the article are digital platforms. The platform approach, the platform economy, which primarily ensures the interaction of market participants, is gaining an increasing number of participants and is becoming more widespread in various industries: from trade to the hotel business and education.

The article analyses the impact of the platform approach on the business model of the organization, namely, on the ability to create consumer value and deliver it to its customers, using the advantages of this approach. The ongoing transformation is more based on information technology, human capital, analytical decision-making tools, and business process flexibility. The paper also analyses the experience related to the implementation of the platforms in various countries and organizations.

The study gives a possible business model of a platform organization and a University that has implemented platform solutions. The authors note that the mistakes made during the implementation of the platform are mostly due to the human factor: employees may not be ready for changes or are not technically educated enough. The indifference of managers also plays a role, because the risks arising from this are neutralized worse than others. To reduce the risks, the authors defined the directions of further research.
