The article deals with the issues of operational diagnostics of reclamation systems, which allow timely prevention of negative phenomena on the system and planning measures to improve its functioning and protect the environment. Operational management of irrigation is carried out in the process of implementing the operational modes of irrigation of agricultural crops in order to consistently ensure optimal soil moisture to obtain maximum yield by optimizing the timing and rates of irrigation based on current and forecast weather, agrotechnical, organizational and economic factors. The operational management of irrigation is most effective if it is based on the use of technical means for the rapid collection and processing of the necessary information in the presence of an appropriate technological service. Systematic (daily) accounting of weather and organizational and economic factors makes it possible to predict soil moisture reserves for the next 5-10 days and adjust the timing and rates of irrigation, taking into account the state of soil moisture in each field. The controlled subsystem is designed to supply and drain water, as well as regulate the reclamation regimes of agricultural lands. The control subsystem provides operational management of water flows in the reclamation system, reclamation regimes of agricultural lands, technical condition of the reclamation system. It makes decisions and transmits control signals or commands to the controlled subsystem, and also receives incoming information about the state of the control object. The general tasks of the indicated operation services are the issues of rational distribution of irrigation water among the relevant parts of the system and water user farms, including irrigation fields; organization of commercial and operational accounting of irrigation water with the mandatory determination of the amount of waste and collector-drainage water; control over the use of irrigation water and the ameliorative state of lands and the natural environment; carrying out maintenance and repair work; implementation of measures to improve systems and increase their technical level; implementation of operational diagnostics on systems and farms.

The article considers the problem of effective use of irrigation water in the cultivation of fodder crops on irrigated lands of the Saratov Trans-Volga region. The main costs in the cultivation of crops fall on the supply of water, so its efficient use becomes one of the main tasks in irrigation reclamation. The possibility of cultivation in this natural and climatic zone of a large number of various forage crops is shown, the features of their cultivation on irrigated lands are considered. Data on the distribution of fodder crops by species are given, the possibility of more efficient use of irrigated lands by introducing intermediate crops into crop rotations is shown, which will allow obtaining a greater yield of fodder units per irrigated hectare. The issue of methodology for conducting water-balance studies on irrigated lands and the determination of individual elements of the water balance equation is considered in detail, their relative values are given. The irrigation regimes for alfalfa, Sudanese grass and sorghum are considered, irrigation norms are given for the years of cultivation, as well as the number of irrigations. The difference in irrigation regimes is substantiated, both for different crops and for different years of research, depending on the natural moisture supply. The values of coefficients of water consumption and use of irrigation water for the considered fodder crops are calculated according to the values of productivity and irrigation norms. In conclusion, a conclusion was drawn about the most rational choice of crops for cultivation in this natural and climatic zone, while maintaining a favorable ecological and reclamation state of irrigated lands and efficient use of irrigation water.

Vital signs are an important component of monitoring the adult or child patient's progress during hospitalization, as they allow for the prompt detection of delayed recovery or adverse events. Vital signs are measured to obtain basic indicators of a patient's health status. The most common intervention performed in hospital medicine is a measurement of vital signs, and these traditionally consist of blood pressure, temperature, pulse rate, and respiratory rate. Advanced monitoring systems incorporate a balanced combination of clinical and technological aspects to give an innovative healthcare outcome. Remote patient monitoring systems are rapidly becoming the core of healthcare deliveries. The paradigm shifted from traditional and manual recording to computer-based electronic records and further to smartphones as versatile and innovative healthcare monitoring systems. This research aims to design a Vital Sign Monitoring device for BPM and SpO2 Parameters with Notifications through the IoT-Based Telegram application. This device can monitor vital signs, especially BPM and SPO2, wherever the patient is and whenever so that doctors or health workers and patients can find out their health condition. This display can be viewed via web thinger.io, then forwarded to telegram if an abnormal patient condition is found, and there is an indicator light that will light up differently for each condition. This study uses the MAX30100, which is a digital sensor to detect oxygen saturation and heart rate. The results of this study have succeeded in displaying data on the IoT web and sending notifications to the Telegram application. And also, the resulting data has an error that does not exceed the allowable limit according to each parameter. The difference between heart rate readings and oxygen saturation values ​​on the device and patient monitor is 0.015% for heart rate and 0.01% for oxygen saturation. This study indicates that it is time to monitor vital signs that can be seen remotely and have a system that is an inexpensive and easy-to-operate device for health workers without interfering with activities of daily living.

Published: March 2022

The increase in the number of patients infected with the Covid-19 virus from day to day shows a fluctuating number. Meanwhile, the spread of the COVID-19 virus is spreading rapidly in various ways and is difficult to predict. Therefore, mapping the spread of the COVID-19 virus is needed. Currently, the existing deployment maps are offline maps that are updated one or more times a day. It does not show real-time deployment and so rapid prevention is not possible. This study aims to develop a mapping system for the spread of the COVID-19 virus in real-time. For this reason, in this study, an Android-based COVID-19 spread monitoring application was developed in real-time using the Prototype Development Model method. The application is developed with an easy user interface to receive it well. The results of the created application show that users who use this application can connect in real-time with the developed map. Furthermore, the location of users who are exposed to or suspected of being exposed to the COVID-19 virus can be displayed in real-time on the developed map. With the map of the COVID-19 spread, it is hoped that early prevention of the spread of the virus and the introduction of patterns of virus spread can be carried out.

Published: March 2022

The basic requirement that must be met in the construction of a bridge is the resilience. This resilience depends upon the supporting of bridge when the load that passes over the bridge. Loading condition on bridge is generally in the form of dynamic which ​​can vary according to crossing conditions on it. This reason validates in difficulties in estimation the lifetime of the bridge. In order to maintain the good condition of the bridge the estimation of overloading condition and its effects of over loading on bridge need to evaluate to keep the bridge durable for that a bridge load measuring detector is needed. The aim of this research is to design an automatic load detector to test the strength of the bridge at dynamic loading conditions. The load detector designed through an Arduino-based load cell sensor. The detector equipped with I2C LCD display mechanism which can display the load on bridge and buzzer switch with warning alarm which can alert when bridge is over loaded. The total sensor mechanism was tested on a miniature wooden bridge with selected loads. During testing, the detector load cell sensors placed at the bottom of the bridge surface with a running load, the readings are considered recorded for several load cells at dynamic loading conditions. In the research work was carried out on the bridge using various load ranges from 100 grams to 25 kilograms on load cells at various positions. From the experimentation it has been noticed that, the load cell has displayed the smaller value as compared with the actual value due to the load distribution over the bridge structure. From the experimental data it is noticed that the average error rate 4.67%, hence the developed sensor system more suitable for practical application to evaluate the damage of the bridge. It also concluded that, the detector is more effective in evaluation of dynamic loading condition to prevent damage of bridge.

Published: March 2022

The majority of Indonesia's population is Muslim, including more than 13,000 people with hearing impairments. In carrying out congregational prayers, the Deaf find it difficult to follow the instructions of the Imam's movement. The presence of hearing aids cannot be used by all persons with hearing impairments, and hearing aids often cause a buzzing sound, thus disturbing concentration. Therefore, in this study, a gyroscope bracelet will be made to assist people with hearing impairments in following the instructions of the Imam's movement when carrying out congregational prayers. The bracelet worn by the Imam will send a code in the form of a change in angle to the bracelet used by the Deaf congregation. The Z angle is a vertical angle in the gyroscope where the Z angle has an angular velocity of 360 degrees per second. The control system uses Arduino nano FT232RL FTDI FT232. The communication module uses HC-12 SI4463, with a wireless frequency of 433.4 - 473.0 MHz. The sensor for detecting changes in motion is the MPU6050 gyroscope sensor, the vibration indicator uses a micro vibrator motor. The bracelet used by the deaf will read the code from the Imam's device, with a notification in the form of a different vibration on every change in prayer movement. After experimenting with 30 people, the percentage of success was 84% ​​for all prayer positions. Thus, the gyroscope bracelet tool for prayer guides for the Deaf can help the Deaf community in carrying out congregational prayers.

Published: March 2022

Recent years, advances in the internet and communication technology have enabled the proliferation of digital medical devices with innovations in health applications, including for visual acuity examination. However, the validity of these applications remains unclear. The limited mobility and health service during the COVID-19 pandemic underscores the urgent need to conduct research that validates these electronic device-based applications. Thus, this study aims to critically analyze whether the electronic device-based application can provide a valid and high-quality visual acuity examination. A systematic review was conducted through studies searching PubMed, MEDLINE, Springer, and Cochrane Library using specific keywords. After the studies were selected through inclusion and exclusion criteria, extraction was carried out. Publications from 2011 to the end of 2021 were reviewed, yielding in 1409 studies, of which 19 were included. The results showed a lower systematic bias for distance visual acuity testing with electronic device-based applications than standard reference tests with a mean difference of -0.08 to 0.10 logMAR. The validity of the near visual acuity examination with the application shows better results than the distance examination, which is marked by smaller 95% limits of agreement range. The results of the analysis of Bland-Altman plots in all the studies reviewed showed that the accuracy of the examination results tended to increase in patients who had better visual acuity. In practice, the use of electronic device-based applications for visual acuity examination can increase the work effectiveness of medical personnel and the proliferation of digital medical devices. It can also be one of the breakthroughs in remote medical services and support the implementation of telemedicine policies.

A Survey on Metaverse: Fundamentals, Security, and Privacy
Authors: wang yuntao , Su Zhou , Zhang Ning , xing rui , Liu Dongxiao , Luan Tom H. , Shen Xuemin
Published: March 2022

Metaverse, as an evolving paradigm of the next-generation Internet, aims to build a fully immersive, hyper spatiotemporal, and self-sustaining virtual shared space for humans to play, work, and socialize. Driven by recent advances in emerging technologies such as extended reality, artificial intelligence, and blockchain, metaverse is stepping from science fiction to an upcoming reality. However, severe privacy invasions and security breaches (inherited from underlying technologies or emerged in the new digital ecology) of metaverse can impede its wide deployment. At the same time, a series of fundamental challenges (e.g., scalability and interoperability) can arise in metaverse security provisioning owing to the intrinsic characteristics of metaverse, such as immersive realism, hyper spatiotemporality, sustainability, and heterogeneity. In this paper, we present a comprehensive survey of the fundamentals, security, and privacy of metaverse. Specifically, we first investigate a novel distributed metaverse architecture and its key characteristics with ternary-world interactions. Then, we discuss the security and privacy threats, present the critical challenges of metaverse systems, and review the state-of-the-art countermeasures. Finally, we draw open research directions for building future metaverse systems.

Published: March 2022

This research was conducted on a degraded Ultisol at the Eastern farm of the Michael Okpara University of Agriculture, Umudike during 2014 and 2015 planting seasons, to study the effect of sawdust and poultry manure combinations on soil exchangeable properties. The treatments comprised of sawdust (SD) at five levels namely 0, 2, 4, 6 and 8 t/ha and poultry manure (PM) at five levels namely 0, 5, 10, 15 and 20 t/ha, which were combined to produce 25 treatment combinations. The treatment combinations were laid out in Randomized Complete Block Design (RBCD) and replicated three times in a factorial experiment. The interactions of poultry manure and sawdust significantly (p<0.05) improved soil bulk density and total porosity with the lowest value obtained with 0t/ha SD + 8t/ha PM in both 2014 and 2015. The result showed that the interactions of poultry manure and sawdust significantly (p<0.05) increased the leaf area with the highest value obtained with 20t/ha SD + 8t/ha PM in both 2014 and 2015. Also, only the various rates of treatment applied significantly (p<0.05) increased the number of leaves, plant height, leaf area and cocoyam yield with the highest value obtained with 20t/ha SD + 8t/ha PM. Also, the various rates of treatment application significantly (p<0.05) increased the cocoyam yield (weight of corms and cormels) with the highest value obtained with 20t/ha SD + 8t/ha PM. Improvement in growth and yield of cocoyam resulted from the improved nutrient status of the soil as a result of the amendments applied.

Published: March 2022

Soil aggregate stability is a vital indicator for improving soil quality and controlling soil losses. This study aimed to assess the effect of fallow forage legumes and fertilizer application on wet and dry stability aggregate and soil organic carbon on Alfisols of Guinea Savanna, Nigeria. The study was conducted at the Institute for Agricultural Research (IAR) experimental field, Samaru Zaria. Treatment consisted of 3 plots (Centrosema pascuorum (Cp planted), Macrotyloma uniflorum (Mu planted) and control-natural vegetation regrowth). The soil samples collected were dried at room temperature and then separated into six aggregate fractions. Aggregate stability assessment results showed that dry stable aggregate fraction was significantly influenced by fallow management practice where Cp planted fallow recorded the highest amount in soil aggregate sizes of 2000 μm (0.99 g kg-1). Concerning wet stable aggregate, the proportion of 2000 μm sized aggregate fraction had the highest value (0.22 g kg-1) under treatment Cp. However, 0 kg N ha-
1 -1
produced the highest quantity in 2000 μm (0.23 g kg ) sized stable aggregates, and there was no significant difference in Nitrogen and Phosphorus application rates. The wet mean weight diameter (MWD) was significantly affected by forage legume with Mu planted fallow having the highest value (0.40 g kg-1) while the dry MWD aggregates with Cp recorded the best value (1.37 g kg-1). Cp planted fallow sequestered more carbon (0.65 g kg-1) in the 500 µm aggregates fraction. NVR contributed the highest carbon (0.80 g kg-1) under 50 µm sized aggregates. For carbon content in <50 µm sized aggregates, Mu produced the highest carbon (0.72 g kg-1) in the fraction. Conclusively, the type of management practices affects the soil aggregation size fractions, which increased soil organic carbon sequestered.

The study investigated the soil chemical properties of Nworie river watershed prone to erosion in Owerri- Imo State, Southeast Nigeria. The study area was divided into Upstream, Midstream and downstream. Five Major gullies were used for the study. Soil samples were collected from the walls of the gullies beginning from down to up according to apparent horizon differentiation. Soil profile pit was dug 100m away from the degraded area, and this served as the control. Soil data collected were subjected to statistical analysis. The soils of the watershed were acidic. The results of some chemical properties for soil quality evaluation were matched with the FAO standard to assess the degree of degradation. The soil nitrogen content of the watershed ranged from 0.01% to 0.02%, Potassium ranged from 0.16cmol/kg to 0.31cmol/kg, available phosphorus ranged from 1.64Mg/kg to 6.13Mg/kg, Base Saturation ranged from 61.5% to 81.5%, ESP ranged from 2.37% to 9.42%, while organic matter content ranged from 0.30% to 2.09%. Based on the degree of degradation; the watershed was found to be very highly degraded (VHD) due to the low content of organic matter. Erosion within the watershed was more pronounced at the upstream and midstream compared to the downstream.

Introduction: Chronic rhinosinusitis (CRS) is a common and persistent illness that otorhinolaryngologists encounter commonly. It is an important cause of morbidity and accounts for major loss of income. Anatomical variations of the lateral wall of the nose have been reported which can predispose to CRS. The aim of the present study was to determine the percentage of concha bullosa in patients with CRS and to ascertain its relationship with chronic rhinosinusitis. Aim of the study: To determine the percentage of concha bullosa in patients with chronic rhinosinusitis and to determine the relationship between concha bullosa and chronic rhinosinusitis. Methods: This was a hospital based prospective one-year study done during the period from June 2019 to December 2020 was conducted at the outpatient department of ENT, Shaheed Monsur Ali Medical College and Hospital, Uttara, Dhaka, Bangladesh. Sample size in this study were selected 57 patients. Result: Of the 57 patients in our study, 21 were males and 36 were females (Figure-1). Of these 36.84% male patients 21 showed concha bullosa and of the 63.84 female patients 326 showed concha bullosa on CT nose and PNS and DNE. The most common age group showing concha bullosa was 21-30 years 23(40.35%) (Table 1). The most common symptom found in our study was headache in 57(100.00%). The next commonly occurring symptom was nasal block 51(89.47%) followed by nasal discharge or nasal purulence 48(84.21%). DNE and CT scan of nose and paranasal sinuses (coronal and axial) were studied for the evaluation of concha bullosa in our patients of CRS. Concha bullosa was noted in 33(57.89%) patients having unilateral and bilateral presentations. Conclusion: Concha bullosa is one of the most common anatomical variations of the lateral wall of the nose. The presence of concha bullosa plays a significant role in the development of chronic rhinosinusitis particularly in chronic maxillary sinusitis.

Published: March 2022

Exporting companies survive in an increasingly volatile and unpredictable environment, characterized by technological development and acute competition linked to the globalization of economic activities. Exporting has a positive impact on the trade balance of countries, especially in times of crisis, on the level of employment and on the improvement of the standard of living in general. The challenges faced by exporting companies and the actions they need to take in order to be more successful must be systematically addressed. The authors of this article have highlighted the key factors that can help companies to be more competitive and successful in exporting, based on theoretical approaches carried out in this field. The MICMAC method was used to identify the determining factors that can influence the performance of companies in exporting. The variables used in this research were identified based on the review of existing literature. 21 variables were collected and classified into 7themes. The results of the structural analysis were prioritized by performing a sensitivity analysis to prioritize the key factors. It was found that three factors condition the export performance of firms: strategic factors, management profile, commitment and international experience were found to be related to the export performance of the firm. The results of this research were used to develop recommendations for business leaders, practitioners and policy makers. The authors hope that this advice would help Tunisian firms' export performance in the future.

The Numerical Simulation of Properties with High Angular Speed & Low Angular Acceleration in Three & Five Freedoms of Robotic Arm I
Authors: Xu Run
Published: March 2022

In robot design and application the force and angle with angular speed is important so this study will model numerical simulation and discuss detail data to investigate their property. The force may increase as arm 1 angle increases whilst it may increase if angular speed increases in three freedoms. Meantime it will decrease if angular acceleration increases. It is found that with the angular speed increasing all three forces may increase whilst the angular acceleration will cause its increase too in five freedoms. From this value it is observed that F2 is prior one to ensure the strength and fatigue life then F2 is second one to estimate its strength whilst F3 may be neglected. The force may increase as arm 1 angle increases whilst it may increase if angular speed increases in three freedoms. Meantime it will decrease if angular acceleration increases. There is big distance to attain 5KN between the conditions. The effective factor turn to the force is F1>F3>F2 in three freedoms. The force may increase from 15N to 15KN and 18KN with F3, F2 and F1 in five freedoms. Among them F3 is the least one and F1 is the biggest one. The effect factor turn is F1 >F2 >F3. so the F1 and F2 is important one while F3 is neglected.
