Published: August 2021

Data on Crustacea from underground waters accessed through wells are limited in Poland. A recent study was undertaken to determine diversity and factors influencing the crustacean communities inhabiting wells drilled in three bedrocks, Jurassic limestone, Cretaceous marls and flysch. A total of 23 crustacean species and subspecies were recorded belonging to Copepoda, Ostracoda, Amphipoda and Bathynellacea. Only four species of low abundance, however, were stygobionts. Our studies showed that abundance and species number of Copepoda and Ostracoda were affected by bedrock geology (with higher abundances and species richness in wells of Cretaceous marls), and in the case of copepods, also by sampling season. Furthermore, this paper lists all species of Crustacea recorded from inland groundwater habitats of Poland based published over the last 133 years. The most species-rich group was Copepoda with 43 representatives (four stygobites), followed by Ostracoda and Amphipoda with a total of 37 and 12 species, respectively (each with nine stygobites). In addition, two species of Isopoda (one stygobite) and one Bathynellid appear in the checklist. The checklist identifies geographical (and environmental) gaps which require further research.

This study focused on the monitoring and assessment of aquatic ecosystem functioning based on the abiotic and biotic features of Lake Nasser in the post-flood and pre-flood periods as the last ones before water storing behind the Grand Ethiopian Renaissance Dam. The physicochemical parameters, distribution and structure of biotic communities, including bacteria, phytoplankton, zooplankton, macrophytes, epiphytes and fish were analyzed at 15 sites. The values of most parameters (primarily temperature, total suspended solids, pH, orthophosphates, carbonates, sulphates and some cations) were higher in the pre-flood period, whereas higher values of conductivity, total dissolved solids, total solids, nitrites, nitrates, chemical oxygen demand, bicarbonates and chlorophyll a were recorded in the post-flood period. Cyanobacteria-dominated phytoplankton and total coliform bacteria were more abundant in the pre-flood period, and especially at sites 10–15, whereas higher abundances of zooplankton were recorded in the post-flood period. All these changes in parameters were significantly differentiated, and only the concentrations of dissolved oxygen, biochemical oxygen demand, ammonium and silicates were at similar level in both periods. The study also indicated that environmental factors had affected the macrophyte distribution and the adaptation of the invasive species Myriophyllum spicatum to thrive under different environmental factors in the lake. Besides, macrophytes provided the habitat to other aquatic organisms, especially epiphytes, and also helped maintaining the good water quality, nutrient cycling and stabilizing rivers’ and lakes’ banks. Generally, these conditions were rather favorable for biological processes and fish production.

Published: August 2021

Chronic salpingo-oophoritis (CSO) is one of the most common diseases among the entire gynecological pathology, the frequency of which reaches 65-68%. Despite the progress made in the treatment of CSO, there is a serious problem due to the steady growth and complications leading to infertility, ectopic pregnancy and the development of chronic pelvic pain syndrome, which significantly reduces the quality of life of patients. In this regard, the development of promising pharmaco-physiotherapeutic methods with pronounced analgesic, anti-inflammatory, immunomodulatory and bacteriological effects to increase the therapeutic effectiveness and improve the quality of life of patients with salpingo-oophoritis is an important task of modern gynecology and physiotherapy. Objective: To study in a comparative aspect the effect of the combined use of transvaginal electrophoresis of the collagenase complex and pulsed magnetic therapy and their mono-effects on the quality of life of patients with chronic salpingo-oophoritis. Materials and research methods. The study included 77 patients aged 18 to 42 years (median age was 26,7±2,8 years) with a diagnosis of chronic salpingo-oophoritis of non-specific etiology. More than half of the patients (59,7%) were women under 25 years of age. All patients were divided into three groups that were comparable according to the main clinical and anamnestic data, somatic and obstetric-gynecological status: group 1 — the main group — included 28 patients who received a course of combined application of transvaginal electrophoresis of the collagenase complex and pulsed magnetic therapy; group 2 — comparison group 1 — included 25 patients who received acourse of transvaginal electrophoresis of the collagenase complex; group 3 — comparison group 2 — included 24 patients who received a course of pulsed magnetic therapy. The quality of life was assessed by the indicators of the Quality of Life Index (QOL), which takes into account the three most important and informative aspects of patients’ lives: physical condition and its dynamics, mental (psychological) health and daily functioning. The results of the study. Based on the obtained results, it was proved that the most pronounced results were achieved in patients of the main group who received a course of transvaginal electrophoresis of the collagenase complex in combination with pulsed magnetic therapy, where the quality of life improved by 89,3% according to the QOL index, compared to the monotherapy with transvaginal electrophoresis and pulsed magnetic therapy — 75,7% and 73,1%, respectively.

This study is devoted to assessing the effect of a single simultaneous exposure to a low-frequency electrostatic field and transcranial magnetic therapy on non-specific systemic adaptation mechanisms. Objective: to evaluate the effect of a single combined exposure to a low-frequency electrostatic field and transcranial magnetic therapy on the stress-realizing and stress-limiting systems of the human body. Material and methods of research. The study involved 83 male volunteers aged 25 to 38 years (the average age was 31,4±0,33 years), who did not have any chronic diseases and risk factors for their development (the first health group), who were divided into four groups by simple fixed randomization. The first group (control group, 21 people) received placebo treatment (imitation of physiotherapy treatment with the device turned off). In the second group (main group 1, 20 people), the volunteers were singly exposed to transcranial magnetic therapy with traveling magnetic field (TMT TMF) using the device «Amo-Atos» with the attachment «Headband» (RU from 18.11.2011 №FSR 2011/12325). In the third group (main group 2, 21 people), the volunteers were singly exposed to low-frequency electrostatic field (LFESF) using the multifunctional therapeutic system «Khivamat-200» (RU from 12.04.2017 №RZN 2017/5597). To assess the stress-realizing and stress-limiting systems of the body, an analysis of heart rate variability (HRV) was performed, which allows determining the tone of the sympathetic and parasympathetic parts of the autonomic nervous system (ANS). Blood levels of ACTH, cortisol, glucagon, LPO products (malondialdehyde (MDA) and Schiff base (SB)), as well as insulin and the activity of antioxidant enzymes (SOD and catalase) were measured. The study was carried out three times: in the initial state, after 30 minutes, and a day after the end of the single exposure to the complex of physiofactors. The results obtained allow concluding that the criteria for the optimality of a combined single exposure to physiotherapeutic factors is a stable activation of stress-limiting mechanisms against the background of an initial moderate increase and gradual diminishment of stress-realizing manifestations. The dynamics of the estimated indicators observed a day after the exposure indicates the increasing adaptive capabilities of the body to minimize stress-damaging effects. A single simultaneous application of physiotherapy factors demonstrated the possibility of targeted implementation of the strategy of adaptation and control of the severity of physiological, hormonal and metabolic changes within the framework of a non-specific stress response, which opens up new opportunities for optimizing the treatment process.

Authors: Mohammed Matrood Mustafa , Ahmed Nassar Ameen
Published: August 2021

The purpose of this research is to control a quarter car suspension system and also to reduce the fluctuated movement caused by passing thevehicle over road bump using modified PID (Proportional Integral and Derivative) controller. The proposed controller deals with dual loopfeedback signals instead of single feedback signal as in the conventional PID controller. The structure of the modified PID controller wascreated by moving the proportional and derivative actions in the feedback path while remaining the integral action in the forward path. Thus,high accuracy results were obtained. Firstly, modelling and simulation of linear passive suspension system for a quarter car system wasperformed using Matlab – Simulink software. Then the linear suspension system was activated and simulated by using an active hydraulicactuator to generate the necessary force which can be regulated and controlled by the proposed controller. The performance of whole systemhas been enhanced with a modified PID controller.
Experimental Study on Shear Strengthening of Reinforced Concrete Beams Using Different Techniques of Concrete Jacketing
Authors: F. Ojaimi Mohammed
Published: August 2021

A large number of RC structures or at least some of their members need strengthening or rehabilitation. Among the typical failure modes, the shear failure is more dangerous and less predictable, because of usually brittle behavior and sudden collapse. Therefore, there are necessities for upgrading the shear capacity and the local ductility of reinforced concrete beams. In this study, four different techniques of concrete jacketing were used to improve the behaviors of the shear deficiencies beams. The four techniques used in this study to enhance the behavior of the beams were by using a Self-Compacted Fiber Reinforced Concrete jacket without stirrups (S.-J. + Steel Fiber), a concrete jacket of Self Compacted Concrete with stirrups (S.-J. + Stirrups), a concrete jacket of ferrocement jacket (S.-J. + Ferrocement), and a concrete jacket of ferrocement jacket with external steel reinforcing bars (S.-J. + Ferrocement + R). These techniques contributed to enhancing the load-carrying capacity and delaying the appearance of the first crack in tested beams compared with the control beam by a percentage of (35, 59, 30, 6) % and (18, 35, 81, 80) %, respectively. The specimen (S.-J. + Stirrups) showed the best performance in comparison with the other used strengthening techniques used in this study in terms of stiffness and the ultimate load-carrying capacity. The ferrocement jacket (S.-J. + Ferrocement) was found to be the most suitable jacketing system used to enhance the shear capacity in terms of cracking load.

Published: August 2021

the possibility of obtaining structural and thermal insulation foam concrete of non-autoclave hardening with improved construction and technical characteristics for the device of a thermal insulation layer in the con-struction of road pavement due to three-dimensional dispersed reinforcement with polypropylene fiber is theoretically justified and experimentally confirmed. Based on the results of studies of the influence of technological factors on the properties of foam concrete, the optimal content (up to 0.25% of the cement mass) and the length (12 mm) of reinforcing polypropylene fibers have been established, which allows ob-taining high strength indicators of dispersed-reinforced cement stone for bending (an increase of 12-20%) and compression (an increase of 6-12%) compared with non-reinforced cement stone of non-autoclaved foam concrete. The analysis of the process of structure formation of dispersed reinforced foam concrete from the standpoint of a systematic approach based on multifactorial polynomial models of the influence of the ratio of filler and binder, as well as the number of dispersed reinforcing fibers, which is determined by the optimal conditions for the distribution of solid and gas phases, as well as the reinforcement of adjacent interstitial partitions of foam concrete, linking them into one asociate, which ensures the joint work of the material under various external influences. A method was developed to increase the durability of the road surface and eliminate the influence of the frost heaving effect on the quality of the road surface by intro-ducing the necessary amount of effective thermal insulation layer into the road surface design. The analysis of the regularity of the heat transfer process in the soil mass of the roadbed and multilayer road pavement is carried out. Based on the analysis, the values of the necessary resistance to heat transfer of road pavement for the natural and climatic regions of the country are determined and a method for calculating the value of the thermal insulation (frost-proof) layer of road pavement is proposed. A method was developed for calcu-lating the value of the thermal insulation layer using monolithic fibre foam concrete and a nomogram to de-termine the required value of the thermal insulation layer made of monolithic non-autoclaved structural and thermal insulation fibre foam concrete of classes D600-D1000.

Entendiendo como "usos" de Foucault no solo a las citas directas, sino más bien sus diferentes recepciones, significaciones y reelaboraciones de sus pensares por otres, para ser puestos en juego en diversas redes de problemas acerca de la educación y el cuerpo. De este modo analizamos el contexto y la producción académica de Foucault, y su posterior resignificación en el campo de la Educación, tanto en el mundo anglosajón, como en Latinoamérica. Partiendo precisamente de la producción académica que realizaron diversos autores que hacen "usos" de Foucault, en este campo y en múltiples contextos de análisis. Junto a su resignificación en el campo de la Educación Física en general, tanto en Argentina como en Brasil, y donde finalmente realizamos una investigación detallada acerca de cómo fueron situados, resignificados, y contextualizados los usos de Foucault en el Profesorado Universitario en Educación Física (PUEF) de la UNLP.

Published: August 2021

Indoor Positioning system (IPS) is the technology that is used to locate smart phones, people or other objects inside a building where Global Positioning System (GPS) doesn’t work or lack precision such as airports, underground locations, parking, multi-storey buildings etc…There is no fixed standard for implementing IPS rather it could be customized according to the location chosen. IPS in turn uses a number of technologies such as Wi-Fi, Bluetooth, Beacons, magnetic positioning, dead reckoning etc…Among the various technologies available studies prove that Magnetic localization provides a most efficient solution for Indoor positioning. Our paper focuses on building an indoor navigation mobile application for a retail store that allows users to search for a product and navigate them to the particular aisle in which the product is located. There by enabling the application to be location sensitive and context aware. In order to collect magnetic fingerprints and convert the obtained data into latitude and longitude values we make use of an API called IndoorAtlas, which helps in locating smart phones inside a building using the accelerometer, gyroscope, magnetometer and Bluetooth in a mobile. Magnetic localization is the concept where deflections of magnetic field from the steel structures inside the building will be captured by the magnetometer and other sensors within a mobile and that will be used to locate a smart phone inside a building. The same application could be utilized for various use cases such as Supermarkets & Hypermarkets, museums & galleries, Libraries, Hospitals, Airports & stations, Shopping malls, Exhibition and Conferences.

Published: August 2021

Hospital is one of the most important and beneficial public services in the world, therefore, these facilities should be located in a rational manner. Increasing the population of countries particularly developing countries and remote areas leads to the demand for new public health facilities and hospitals. No matter who provides the healthcare facilities, the most important issue is where to locate a new hospital to provide, both facility location and attractiveness. Hospital proper site selection has a vital role in hospital construction and management. From the aspect of the government and healthcare organization, appropriate hospital site selection will help optimize the allocation of medical resources, matching the provision of health care with the social and economic demands. From the aspect of the investors and operators of the hospital, optimum hospital site selection will definitely be cost-saving on capital strategy. On the other hand, establishing a hospital in urban districts has its own positive and negative consequences. The positive impacts of establishing a hospital in an area are that it increases property value in the neighboring periphery as well as improving healthrelated accessibility for the residents of that urban district. The negative impacts of establishing a hospital in an area are negative side-effects such as environmental contamination and inducing new waves of traffic flow. Then, the adjacent community is impacted by forms of increased traffic flow, increased emergency vehicle usage in residential areas. Therefore, in hospital site selection should be tried to reduce the negative impacts. Then, main aim of this paper is to select a site for the building of a new hospital in Iskandar Malaysia using GIS-based Multi-Criteria Analysis (MCA) with consideration of various factor criteria, and constraint criteria in order to balance the medical resource there.

A Topology Identification Method to Enhance the Linear Estimation of Generator Rotor Speeds
Authors: Gotti Davide , Ledesma Pablo , Amaris Hortensia
Published: August 2021

This paper proposes a methodology to avoid biased estimations of generator rotor speeds under network topology changes. The algorithm is based on deep neural networks and executes topology processing considering the relevant branches for rotor speed estimations. The proposed technique uses the measurements from the same phasor measurement units (PMUs) needed to carry out generator rotor speed estimations; thus, it does not imply an additional cost for the transmission system operator. The proposed methodology is demonstrated with a centralized and distributed approach, using a modified version of the New England test system and the IEEE 118-bus test system, respectively. The numerical results on both test systems demonstrate the reliability and the low computational burden of the proposed algorithm.

An analytical description of the process of making helical surfaces with a disk tool with a substantiated definition of the objective function is proposed. By analogy with coordinate metrology, it is proposed to adopt a minimum tolerance zone as an objective function. This allows to specify the required solution error and eliminates the need to use normal lines or tangents to the profiles. An example of calculating the profile of a helical groove of a twotoothed end mill, performed with an error of 0.05 mm is presented.
Keywords: helical surface, disk tool, computer support, optimization, minimum tolerance.

Published: August 2021

The hydraulic drive of a construction machine is a complex dynamic system that is subjected to many dynamic loads of a variable nature and operates under conditions of variable external influences caused by various factors. During operation, these loads cause failure of the hydraulic transmission elements. To prevent these malfunctions, technical diagnostics should be applied by determining their current technical condition and remaining service life. The article assesses the working condition of hydraulic cylinders using a mathematical model. Using matlab/simulink software to simulate the hydraulic cylinder and hydraulic piston speed when changing the hydraulic cylinder clearance. The simulation results are presented.

The article shows that in comparison with hydraulic and electric auxiliary braking systems, the engine brake has a simpler design, several times lower weight and cost. It can be installed in the exhaust pipe of almost any car, and its application gives a significant socio-economic effect. A mathematical model has been developed for the theoretical study of the power of motor brakes with a constant choke and with an electro-magnetic valve. A theoretical study of the ZMZ-406 engine with a motor brake with a constant choke and an electromagnetic valve has been carried out. The analysis of the research results showed that a motor brake with an electromagnetic valve provides a greater braking power of the internal combustion engine, and, consequently, a better vehicle braking efficiency.

Our Bangladesh education system has been worse after the covid 19 pandemics as today’s world is highly interconnected. The severe risk is the outbreak of this virus is not limited to the national border rather worldwide. It has created extreme unfavorable pressure regardless of education level, gender or income. In this research paper, our main objective was to discover the condition of the Bangladesh education system before and after the pandemic. In our country, after the surge of covid 19, the outcome of the unemployment problem, Cost of education, academic performance, Quality of teaching, has been altered undoubtedly. The data was collected from students of Dhaka and Chittagong cities. In our study, 52% of respondents were male, and 48% were male. The age proportion of the majority of the students (57%) is from 20-30. The education level of 85% of respondents is Graduation and Post-graduation. 48% of respondents are satisfied current education system of Bangladesh, but 40% of respondents are not satisfied as they perceive that the current education system of Bangladesh needs to be changed. Independent variables have been selected for this research. Our prominent was to identify how the variables impacted Bangladesh education system In Chittagong city, 57% of respondents believe that after the COVID pandemic, the Cost of education has been decreased.
On the other hand, in Dhaka city, 67% of respondents convince that the Cost of education was declined. In the lockdown period, 50% of students of Chittagong city had spent most of the valuable time developing skills, whereas 34% of students in Dhaka city spent their time developing skills.
For descriptive statistics, Bar chart, column chart, pie chart, etc., was used. For inferential statistics, Minitab and Excel were used. All of the three variables are categorical. A Chi-square test was performed to estimate the relationship between variables Bangladesh education systems.

In the current research, advanced studies on the effect of transition metal doped Iridium (IV) Oxide (IrO2) nano thin films in cancer cells, tissues and tumors under synchrotron and synchrocyclotron radiations is investigated. The calculation of thickness and optical constants of Iridium (IV) Oxide (IrO2) advanced studies on the effect of transition metal doped Iridium (IV) Oxide (IrO2) nano thin films in cancer cells, tissues and tumors under synchrotron and synchrocyclotron radiations produced using sol-gel method over glassy medium through a single reflection spectrum is presented. To obtain an appropriate fit for reflection spectrum, the classic Drude–Lorentz model for parametric di–electric function is used. The best fitting parameters are determined to simulate the reflection spectrum using Levenberg-Marquardt optimization method. The simulated reflectivity from the derived optical constants and thickness are in good agreement with experimental results.

I feel the need to divide that into two categories; formal relationships and informal relationships. In this case, formal relations are based on politics and military, that is, relationships that were built in the 16th century. The farther away the year, the more cryptic the sources will be. But since the 1530s, Acehnese envoys began to appear in Istanbul, and they were involved in Aceh-Ottoman cooperation. They came to ask for military assistance to fight Portuguese colonialism in the region. By conducting literature study, verification, and interpretation, the author returns to the description of a brief history through the sources written when the Ottoman Turks were still standing. In Muhamad Farid Beik's work, which tells the Ottoman Turkish Government sent a complete fleet to the Archipelago complete with the crew and others. This means that formal relations were established before 1530 AD. After that, there had been diplomatic and military relations between the two sultanates. Turkish cannons that were brought to Aceh are still in the Dutch museum. The relationship between the Ottoman Turks and the Nusantara was not only based on benefit but also based on panic Islamism in facing the same enemy, namely the Portuguese colonialists. When Indonesia faced the Dutch, the Ottoman Turks still provided informal assistance through volunteers due to Western pressure, mainly the British.
