Published: July 2021

Recent technological advancements have made things in an efficient manner. This paper presents the overall design of Dual-tone multi-frequency (DTMF) signaling with little cost and establishes a new pattern for home automation developments. The benefits of a DTMF system is that it may be controlled remotely from afar, effectively saves energy, minimizes human stress. One of the most developing trends in home appliance control innovation is DTMF-based home automation technology using Arduino. In order to make this project work, an Arduino Uno was used. This is primarily about the ATmega328 microcontroller (MCU). It comprises of 14 digital output/input pins, analogue inputs of about 6 ports, a USB port for programming the onboard microcontroller, an ICSP header, a power jack, and a reset button. DTMF can be realized using numerous approaches for example, Discrete Fourier Transform (DFT), and Genetic Algorithm (GA). These techniques are generally analyzed using MATLAB, GUI, and FPGAs. DFT procedure has the shortcoming of power overwhelming and necessitates supplementary hardware. The system design in this project work was implemented with C++ programming languages on the Arduino IDE software. The circuit diagrams were modeled using the use of Proteus software.

Authors: Sundararajan Raghul Suraj , Tariq Iqbal M.
Published: July 2021

The dynamic modelling of a solar energy system with vehicle to home (V2H) and vehicle to grid (V2G) options for Newfoundland conditions is discussed in this paper. A site (13 Polina Road) was chosen in St. John's, Newfoundland, Canada. An optimized system was built for the chosen site using BEopt, Homer, and MATLAB software’s to meet the house's energy demand. Furthermore, smart current sensors installed in the house are used to incorporate the V2H and V2G concepts. The Nissan Leaf's battery is used to supply household loads in V2H operation mode when the power supplied by the PV panel and the storage energy in the inhouse battery is less than the load's energy demand. In V2G mode, the vehicle is only linked to grid. Along with the simulation results, detailed system dynamic modelling is also presented. There are nine different system control modes that are proposed and simulated.

Authors: Elsiragy M. N. Massoud
Published: July 2021

— Structure’s systems are subjected to additional loads due to earthquakes that may be produces progressive failures. The building illustrates dissimilar categories of failure mechanism for the minor to major earthquake conditions. These structures categorized to the most susceptible type of building has experienced serious hazard or even full failure for the period of seismic activities, therefore their investigation is a complex thing to do. Consequently, this research aims at studying the behaviour of large-scale model of structures constructed with and without brick walls under seismic conditions. The effect of building walls on the performance of the structure during earthquake loading is investigated numerically using PLAXIS 3D software. An eight story building with basement designed on a mat foundation is simulated as three-dimensional model in case of brick walls existing and without brick walls case. The effect of existence such wall building on the stability of foundation soil system is discussed in the form of lateral, horizontal deformation, and foundation acceleration. The studied showed that the reduction of extreme horizontal displacement and bending moment for building foundation with brick walls reached to 43%, and 68% respectively compared to the building without walls. The consideration of wall as filling for super structure significantly reduce the foundation acceleration by as much as 72% of its initial value, which lead to considerable effect of increasing the foundation stability.

The increasing of employee salary is one of the mechanisms to maintain the good employee performance. The decision of periodic additional salary for a certain employee is the difficult task even in some cases this is a sensitive issue. To minimize such as those problems, the fair additional salary computation performed by system can be chosen as the way out. The study presents the application of fuzzy inference system (FIS) to determine the additional salary computation. This study uses the real dataset collected from a local drinking water distribution company. The experiment results confirm that the method is feasible to be applied for this purpose. This feasibility conclusion is supported by the little deviation between manual computation results compared to FIS. For almost all cases, the FIS provides more detail results.

Published: July 2021

The purpose of this research work is to comparatively study the oil recovery factor from two major aquifer geometry (Bottom and Edge water aquifer) using water aquifer model owing to the fact that most if not every reservoir is bounded by a water aquifer with relative size content (Most Large). These aquifers are pivotal in oil recovery factor (percent%), Cumulative oil produced (MMSTB) as well as overall reservoir performance the methodology utilized in this study involves; Identification of appropriate influx models were utilized for aquifer characterization. The characterizes of the Niger Delta reservoir aquifer considered include aquifer permeability, aquifer porosity etc. Estimation of aquifer properties is achieved by using regressed method in Material Balance Software (MBAL). This approach involves History Matching of average reservoir pressure with computed pressure of the reservoir utilizing production data and PVT data. The computed pressure from model is history matched by regressing most uncertain parameters in aquifer such as aquifer size, permeability, and porosity. Historic production data was imputed into the MBAL Tank Model, the production data was matched with the model simulation by regressing on rock and fluid parameters with high uncertainty. The match parameters were recorded as the base parameter and other sensitivity on aquifer parameters using the Fetkovich model for the bottom and edge water drive. The average percentage increase in oil cumulative volume was 0.40% in fovour of bottom water drive. Further sensitivity on cumulative oil recovered showed the increase in reservoir size with increasing aquifer volumes increases oil production exponentially in bottom water drive whereas edge water drive increased linearly. Aquifer volume, aquifer permeability showed linear relationship with bottom and edge water drive.

Published: July 2021

The housing stock in Port Harcourt municipality has over the years experienced incremental deterioration from neglect to change of use, paucity of funds and sometimes misappropriation of resources. The study assessed existing housing stock within Port Harcourt municipality with the objective to ascertain the physical condition of the housing stock in some planned and unplanned neighbourhoods in Orije layout-Orominike (D/Line), Port Harcourt Township and Diobu (Mile1 and Mile 2) and some waterfront settlements. Twenty-five (25) communities were identified from the entire study area. Some indicators such as habitable space, physical condition, availability of basic social infrastructure and services and environmental quality of the housing unit were measured. The sample was drawn purposively as 4 distinct neighbourhoods were studied. A multi-stage sampling technique was deployed, Taro Yamane formula was applied to determine the sample size of 156, as the number of questionnaires to be administered and stratified simple random sampling technique was employed to select respondents with household 5 persons per household of which 148 questionnaires were retrieved. Data from the field were analysed using Statistical Package for Social Sciences (SPSS), aimed at comparing the nature of substandard housing found across the neighbourhoods studied. The result indicates that the housing stock in the indigenous enclaves within the Diobu neighbourhood has a high occupancy ratio and lacked basic public utilities and services in addition to houses being constructed with substandard materials. Residents often experience periodic flooding after rainfalls. The study recommends that to further improve the standard of housing conditions in line with the global UN standards, the provision of basic social infrastructural services alongside periodic and consistent urban renewal processes should be constantly carried out to reduce the housing deficit within the municipality.
Dynamic Deformation Characteristics of Soil in the Tasks of Seismic Micro Zoning
Authors: Kendzera Oleksandr , Semenova Yuliia
Published: July 2021

The article discusses a technique for determining the nonlinear characteristics of the layers of computational models of the soil profile for the equivalent linear and nonlinear modeling of its response to seismic effects. The results of studying the factors influencing the curves of the strain-dependent shear modulus G (γ) and damping ratio D (γ) are analyzed. Based on the results of the analysis, the main parameters have identified that control the shape of the curves and allow you to quickly select the corresponding curves from the existing database with acceptable accuracy for each layer of the soil profile model. For clayey rocks: this is the plasticity index PL and the depth of occurrence; for sandy rocks: particle size, percentage, and depth. The paper presents the results of studying the effect of relative errors that arise when choosing the curves G (γ) and D (γ) for the soil layers of the computational seismic-geological model on the parameters of the frequency response of the soil, calculated using the equivalent linear modeling of ground vibrations during earthquakes. It was found that errors in determining the strain characteristics of soil layers in the calculation model lead to a shift in the maxima of the amplitude-frequency characteristic, to a change in the amplification factors of oscillations, as well as to the appearance of "false" maxima at high frequencies.

The methodological approach to the formation of computational seismic-geological models of soil strata, by introducing the curves G (γ) and D (γ), which reflect the nonlinear properties of the soil, makes it possible to improve the computational methods for determining the resonance properties of soils under construction sites. The most accurate values of the frequency characteristics of the soil strata under construction sites are necessary for the development of effective measures to ensure the seismic resistance of the designed and existing facilities.

As a result, the validity and accuracy of determining the quantitative parameters of seismic hazard at the construction and operational sites under study are increased.

Published: July 2021

The speed of propagation of electromagnetic waves in the Earth’s atmosphere differs from the speed of their propagation in a vacuum, which is one of the main factors that have a significant impact on the accuracy of long distance measurement. This influence is taken into account in long distance measurement with the correction for the mean integral group refractive index of air, which depends on such meteorological parameters as temperature, atmospheric pressure and relative air humidity.
The purpose of this work is to compare the accuracy requirements for equipment designed to measure temperature, pressure, and relative humidity required to determine the above correction by the gradient method using the Euler-Maclaurin quadrature formula (hereafter, the Euler-Maclaurin method) and the formula based on Hermite interpolation polynomials (hereafter, the Hermite method). The requirements for the uncertainty of measurements carried out with the sensors of meteorological parameters, allowing to find the mean integral group refractive index of air, providing length measurements of the baselines of up to 5 km with an expanded uncertainty of not more than 1 mm, are established.

SI-2019 and prospects for improving the accuracy of electrical measurements
Authors: Pavlenko Iurii , Kolbasin Alexander , Vаsileva Olena
Published: July 2021

Increasing requirements for the accuracy of measurements have led to the need to revise the existing International System of Units (SI). The important element of the SI-2019 reform is “the establishment of the SI base units through seven defining constants, the numerical values of which are fixed”.

The approach to the establishment of the measurement units has fundamentally changed. If earlier a definition was given of how the unit is realized, now only the exact numerical values of the fundamental constants are fixed, and their values are expressed in the corresponding SI units. Measurement units are determined on the basis of known physical laws, which include certain fundamental constants.

The article analyzes the changes in SI-2019 related to electrical measurements, and also discusses the prospects for the development of accurate electrical measurements.

Published: July 2021

The article describes the method of conducting representative research to determine the effect of pure gaseous hydrogen and a mixture of hydrogen and natural gas (methane) on the performance and metrological characteristics of household gas meters. The experimental research has been carried out in two stages. 84 membrane and rotary meters have been selected for research. The main aspect of the need for such research is the safety of meters. Before the start of the tests and after each stage, the metrological characteristics of all gas meters on the reference prover are determined. At the first stage, a set of static tests is performed, according to which the internal and external short-term and long-term (42 days) tightness of gas meters are checked. A prototype of the installation layout has been developed to conduct experiments on determining the tightness. The second stage is to conduct a dynamic series of tests. Gas meters are assembled according to the developed scheme and installed for testing on the model of the gas distribution network system. It is recommended to use a drum-type meter as a reference gas meter. The criterion for determining the effect of hydrogen and gas meter is the established change in metrological characteristics after the study.

DA SOBERANIA JURÍDICA À NACIONALIDADE: DA LOCALIZAÇÃO ESTATAL À DESLOCALIZAÇÃO ESPORTIVA
Authors: Negócio Ramon
Published: July 2021

Este trabalho objetiva analisar como conceitos de soberania, cidadania e nacionalidade – tradicionalmente do direito público – são ressignificados pelo direito desportivo. O artigo parte da premissa de que a globalização já transformou a nossa forma de ver o Estado. O Estado e a sua estatalidade passam a conviver também com atores privados. A percepção sobre território, povo e monopólio da sanção ganham novos atores de controle. Com isso, se faz necessário diferenciar soberania jurídica da soberania política para explicar a validade das decisões de estruturas globais privadas, tal como a lex sportiva. Pautada na autonomia privada, a ordem desportiva consegue ser efetiva por causa de seu caráter associativo e de sua hierarquia. A partir de casos concretos e pesquisa bibliográfica, o Tribunal Arbitral do Esporte consegue aplicar dentro de sua lógica interna a ideia de soberania jurídica, cidadania e nacionalidade para garantir a igualdade desportiva. As conclusões apontam que alguns conceitos tradicionais do direito público não dão mais conta para explicar a atuação de atores privados globais, necessitando, assim, de uma reatualização.
Perlindungan Hukum oleh Pemerintah di Masa Pandemi Covid-19
Authors: Wahyuni
Published: July 2021

Pentingnya perlindungan hukum oleh pemerintah di masa pandemi Covid-19 saat ini semakin dirasakan oleh masyarakat sebagai unsur yang terdampak baik secara langsung maupun tidak langsung. Berdasarkan data-data yang dirilis oleh Kementerian Kesehatan Republik Indonesia tentang melonjaknya persebaran Covid-19 membuat pemerintah semakin didudukan pada posisi yang paling bertanggung jawab atas perlindungan hukum terhadap hak-hak rakyatnya. Dengan kondisi yang tidak biasa seperti ini, tentunya pemerintah perlu melakukan upaya luar biasa dalam kedaruratan penularan Covid-19 dengan menetapkan bentuk-bentuk peraturan perundang-undangan maupun keputusan. Kewenangan pemerintah dalam mengeluarkan kebijakanpun dirasakan semakin massif tatkala fakta-fakta dilapangan menunjukkan kondisi penolakan-penolakan serta sikap acuh tak acuh oleh masyarakat. Kondisi inipun yang akhirnya menggugah penulis untuk melakukan analisis secara hukum normatif-empiris dengan menggunakan bahan-bahan hukum serta data lapangan dengan kemudian menyimpulkan secara deskriptif. Berbagai upaya dan langkah hukum telah dilakukan oleh pemerintah baik oleh pemerintah pusat maupun pemerintah daerah untuk menanggulangi kedaruratan wabah Covid-19, namun demikian bagaimanapun upaya perlindungan hukum yang diberikan tanpa adanya peran dan kesadaran dari masyarakat maka upaya tersebut tidak akan memberikan hasil yang efektif. Hal yang kita hindari adalah ketika kemudian pemerintah mengambil langkah tegas dengan menerapkan sanksi bagi yang tidak koperatif, dengan upaya untuk meningkatkan kesadaran hukum seluruh masyarakat atas bahaya dari virus ini sehingga mereka benar-benar melakukan tindakan yang sejalan dengan upaya penanggulangan Covid-19

Authors: Adongbede Erute Magdalene , Aduralere Israel Temitope
Published: July 2021

Mushrooms have bioactive compounds that have antimicrobial, anti-cancer and antioxidant activities among other medicinal benefits. In the present study, we examined the anti-cell proliferation activities of mushrooms from eight genera obtained from the wild in Nigeria. Saccharomyces cerevisiae was used as a model organism to screen mushroom extracts for anti-cell proliferation activity. Polyphenols, high molecular weight polysaccharides and low molecular weight compounds from aqueous extracts were obtained from the test mushrooms using methanol and water respectively. The extracts were screened in vitro at different concentrations of extracts with the CyQuant cell proliferation assay. The high molecular weight polysaccharides from tested mushrooms reduced cell proliferation (96.79% inhibition in Ganoderma multipileum Ding Hou to 66.71% inhibition in Coltricia perennis (L.) Murrill at 10.00mg/ml). Percentage inhibition caused by low molecular weight compounds varied from 94.22% (Ganoderma multipileum) to 76.19% (Coltricia perennis) at 10mg/ml. Percentage of inhibition with the polyphenols varied from 94.12% (Microporus xanthopus Fr) Kuntze) to 79.82% (Coltricia perennis) at high doses. High molecular polysaccharides, low molecular weight compounds and polyphenols from mushrooms have anti-cancer properties. The CyQUANT assay proliferation kit was a very efficient tool for screening extracts from wild mushrooms for anti-cell proliferation activities. Medicinal mushrooms in Nigeria show a lot of promise as a reservoir for drug discovery particularly in the area of cancer research.

Sixteen soil samples were collected from wheat, barley and yellow corn rhizosphere in Abu-Ghraib, Aqraqof, Latifieh,Tarmiah, Jadriya and  of Agriculture in Baghdad university/ Baghdad city. The results found nine phosphate solubilizing bacteria (PSB) isolates (Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8, Y9), formed clear zones on National Botanical Research Institute's (NBRIP) agar. The solubility index (SI) of PSB isolates ranged from 2.00 to 3.66. Y4 have the highest SI (3.66) followed by Y3 and Y6 (3.33). Phosphate solubilization abilities varying from (20.10-39.00 Î¼g.ml-1), Y4 was the highest (39.00 Î¼g.ml-1) followed by Y3 (37.00Î¼g.ml-1). The results of hydrolytic enzymes production showed that almost all nine isolates are able to produce protease and pectinase, while Y1 and Y2 showed negative results in cellulase production. Maximum ability for hydrogen cyanide (HCN) and indole acetic acid (IAA) production were showed byY3 and Y4 isolates. The isolate Y4 was found to be the most efficient isolate, so it was selected identified as Bacillus cereus using biochemical tests confirmed by VITEC 2 compact system. The results of High performance liquid chromatography (HPLC) revealed that Bacillus cereus produce oxalic acid (2.996), citric acid (9.117) and malic acid (3.734). Bacillus cereus (Y4) enhanced the growth of mung bean plants. A significant increase in branches number (12.33), plant length (83.0cm), fresh weight (27.25 g) and dry weight (1.427g) were obtained compared with control treatments. The main objective of this study is to isolate PSB and evaluate their roles in plant growth promotion. The results showed the high phosphate solubilization efficiency of PSB isolates and the identified isolates was found to be good enough for plant growth promoting.

Published: July 2021

Owing to high antibacterial resistance of Pseudomonas aeruginosa, it could be considered as the main reason behind the nosocomial infections. P. aeruginosa has a well-known biofilm forming ability. The expression of polysaccharide encoding locus (pelA gene) by P. aeruginosa is essential for this ability. The purpose of the current research was to determine the biofilm formation in P. aeruginosa isolated from clinical samples and to evaluate the role of the selected PelA gene in biofilm formation using PCR method in Iraqi patients. Results revealed that 24 (96%) isolates were found to have the ability to form biofilm that was remarkably related to gentamicin resistance. Moreover, the pelA gene was found in all biofilm-producers. In conclusion, the results of the current study revealed that the P. aeruginosa biofilm-producer isolates were resistant to the antibiotics in question. Likewise, because of wide spreading, it appears that the pelA gene is related to biofilm formation.

Published: July 2021

Prostate cancer is one of the most common types of cancer in men. A total of 110 Iraqi Arab individuals were included in this study; 60 individuals of them had prostate cancer with increased levels of TPSA (patients group); their age range 52-90 years. They were referred for diagnosis and treatment to the National Al-Amal Hospital for oncology in Baghdad during the period from July 2017 to October 2017. While the other 50 apparently healthy subjects were the control group, their age range similar to patients group. Sera and blood samples were collected from all patients and controls than used to assess for the level of IL-18 and DNA extraction, respectively. The polymorphisms were analyzed using polymerase chain reaction-single specific primer (PCR-SSP), at the position -137 G\C (rs187238) in the promoter of IL18 gene. The genetic polymorphism of the IL18 gene promoter -137G/C (rs187238) was determined and presented with three genotypes (GG, GC, and CC) in prostate cancer patients and controls. Testing for Hardy-Weinberg (H-W) equilibrium revealed that Prostate cancer patients showed insignificant variation in the distribution of IL-18 -137 genotypes (P> 0.05). While the control samples showed significant variation (p â‰¤0.05) between the observed and expected. Comparing patients with controls indicated that IL-18-137 alleles or genotypes showed no association with the risk of prostate cancer development in Iraqi Arab population or protection against them. Serum level of IL-18 was highly significant (P â‰¤ 0.001) increased in patients compared to control. The IL-18 serum levels differences in GG and GC genotypes was significant (p <0.05) between patients and control. While there were no significant differences between the three IL-18 -137 genotypes inpatient or in controls.

Authors: Ali Alya'a R. , Dhannoon Ban N.
Published: July 2021

Faces blurring is one of the important complex processes that is considered one of the advanced computer vision fields. The face blurring processes generally have two main steps to be done. The first step has detected the faces that appear in the frames while the second step is tracking the detected faces which based on the information extracted during the detection step. In the proposed method, an image is captured by the camera in real time, then the Viola Jones algorithm used for the purpose of detecting multiple faces in the captured image and for the purpose of reducing the time consumed to handle the entire captured image, the image background is removed and only the motion areas are processed. After detecting the faces, the Color-Space algorithm is used to tracks the detected faces depending on the color of the face and to check the differences between the faces the Template Matching algorithm was used to reduce the processes time. Finally, thedetected faces as well as the faces that were tracked based on their color were obscured by the use of the Gaussian filter. The achieved accuracy for a single face and dynamic background are about 82.8% and 76.3% respectively.

Published: July 2021

The liver diseases can define as the tumor or disorder that can affect the liver and causes deformation in its shape. The early detection and diagnose of the tumor using CT medical images, helps the detector to specify the tumor perfectly. This search aims to detect and classify the liver tumor depending on the use of a computer (image processing and textural analysis) helps in getting an accurate diagnosis. The methods which are used in this search depend on creating a binary mask used to separate the liver from the origins of the other in the CT images. The threshold has been used as an early segmentation. A Process, the watershed process is used as a classification technique to isolate the tumor which is cancer and cyst.

 The test images are taking five for cancer case and five for the cyst, the geometrical and statistical features are calculated for both cases to identify the identity for each case. The statistical features are obtained from the gray level co-occurrence matrix which is contrast, homogeneity, correlation and energy. The geometrical features are the area of the tumor, the circumference and irregularity. The irregularity tends to lose one of the cyst cases than for cancer because of its shape in more regular than cancer.
Campanian Calciturbidites from Northeast Iraq, Kurdistan Region: Insight into Paleogeography and Source Areas of the Shiranish Formation
Authors: Kamil Anhar I. , Al-Dulaimi Salam , Karim Kamal Haji
Published: July 2021

Calciturbidites are similar to siliciclastic turbidites in structure, texture, basin physiography and processes of deposition; nevertheless, their clasts (grains) are carbonate minerals. Turbidity currents transport carbonate grains from carbonate source areas and coastal areas to the deep basins after passing the shelf (peri-platform). These currents are triggered by short-lived catastrophic events, such as tsunamis, earthquakes, marine slides, and typhoons. The Late Cretaceous Zagros Foreland and Hinterland in NE-Iraq (Kurdistan Region) was an active source for the shedding of voluminous sediments to the deep basin of Zagros Foreland Basin. During late Campanian, Shiranish Formation was deposited in the foreland basin; it occurs in the most famous oil fields in the Middle East and represents hemplagite facies (much diluted turbidite facies). Previous studies have not broached the origins of Shiranish Formation, neither in detail or briefly. Conversely, the present study focused on linking the calciturbidite system to the origin of the deposition of the Shiranish Formation via derivation from main carbonate source areas. Along long distance, the sediments crossed the marginal slope, scoring submarine channels and depositing coarse detrital carbonates before reaching the basin plain. On the plain, mostly the fine fractions have settled down and mixed with pelagic sediment. The calciturbidite evidence could be tracked for more than 40 km in the studied area from the slope and outer shelf (present Thrust Zone) to the basin plain (High Folded zone). In several places, channelized detrital laminated limestones are found inside Shiranish Formation and in the most proximal area near Qaladiza town. Bouma sequences are clearly observable with erosional base and A, B, and C divisions. These calciturbidites are keys for picturing Campanian paleogeography and nature of the source area which was consisted of limestone.

Alterations of Obestatin, Cardiac Markers and Lipid Profile Levels in Type 2 Diabetes Mellitus
Authors: Balaky Hazhar M. , Kakey Ismail S.
Published: July 2021

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 obestatin in both diabetic males and females with both age ranges (40-59 and 60-80 years). On the other hand, the results showed that serum STC, LDL-C, and STG levels were statistically significantly elevated, while that for HDL-C was significantly decreased in diabetic males and females with both age ranges. Concerning the cardiac markers, the results found out that the levels of CK-MB and LDH were significantly increased in type 2 diabetic males and females with both age ranges. The results suggested that a low concentration of obestatin is a significant risk factor for type 2 DM, with a key role for this hormone in the pathogenesis. Accordingly, altered levels of obestatin could be used as an important indicator for type 2 DM. The current study also suggests a direct relationship between lipid profiles, except for HDL, the decreased obestatin level, the increased cardiac function markers, and hyperglycemic status in type 2 DM.
