In general, renting out boarding rooms is a component of the corporate world, which is expanding significantly across all industries. The purpose of this study is to ascertain the regularity of boarding room rentals. Find out how muamalah fiqh analysis relates to the practice of renting daily boarding rooms in Mekar Baru Village, Kota Kisaran Barat District, Asahan Regency is the formulation used in this research. In addition, a review of muamalah fiqh regarding the practice of renting boarding rooms that are still in the first party tenancy period in Mekar Baru Village, Kisaran City District, and a problem formulation regarding the status of boarding room utilization factors during the rental period in Kota Kisaran Barat District, Asahan Regency are addressed in this research Asahan Regency, West.All data or references that have been collected are analyzed and rearranged, and in this case, rental practice uses a descriptive analytical approach.  The study's findings suggest that it is against Islamic law and the terms of the ijarah contract for certain locations in Mekar Baru Village, Kota Kisaran Barat District, Asahan Regency, to rent out boarding rooms to outside parties. Practices that take place between the owner and the third-party tenant, or second tenant, do not adhere to the principles, requirements, or aspects of ijarah. Since the original renter still has the right to rent the room, the owner of the boarding room rental should pay the first tenant after being open and honest with them about any transactions they do with other parties.

Development of a New Lunar Regolith Simulant using an Automated
Program Framework
Authors: Kwon GyeongRok , Kim Kyeong Ja , Yi Eungseok
Published: June 2024

Nowadays, the trend in lunar exploration missions is shifting from prospecting
lunar surface to utilizing in-situ resources and establishing
sustainable bridgehead. In the past, experiments were mainly focused on rover
maneuvers and equipment operations. But the current shift in trend requires more
complex experiments that includes preparations for resource extraction, space
construction and even space agriculture. To achieve that, the experiment
requires a sophisticated simulation of the lunar environment, but we are not yet
prepared for this. Particularly, in the case of lunar regolith simulants,
precise physical and chemical composition with a rapid development speed rate
that allows different terrains to be simulated is required. However, existing
lunar regolith simulants, designed for 20th-century exploration paradigms, are
not sufficient to meet the requirements of modern space exploration. In order to
prepare for the latest trends in space exploration, it is necessary to innovate
the methodology for producing simulants. In this study, the basic framework for
lunar regolith simulant development was established to realize this goal. The
framework not only has a sample database and a database of potential simulation
target compositions, but also has a built-in function to automatically calculate
the optimal material mixing ratio through the particle swarm optimization
algorithm to reproduce the target simulation, enabling fast and accurate
simulant development. Using this framework, we anticipate a more agile response
to the evolving needs toward simulants for space exploration.

Water use of Guinea grass as affected by rainfed local conditions and practices in Sub-Saharan Africa
Authors: Ahmed Shamseddin , M. Ishag Hussein , M. Deifalla Adil
Published: June 2024

Ongoing efforts are currently being made to rehabilitate drought-affected pastures in Sub-Saharan Africa. One approach being explored is the introduction of non-native grass species, such as Megathyrsus maximus (Guinea grass). This study aims to investigate the water use of Guinea grass in semi-arid environments under rainfed conditions. Additionally, it aims to a better understanding of the variability of water use in Guinea grass through the utilization of the Bagging machine learning algorithm. Split-plot field experiments were carried out over two consecutive rainy seasons (2020-2021). The treatments included two in-situ rainwater harvesting practices, RWH (ridging plus terracing and terracing alone), three seeding rates, SR (1.5, 2.5, and 3.5 kg ha-1), and two soil nitrogen fertilization rates, SF (95 kg N ha-1 and 0 kg N ha-1). These treatments were compared to a control plot that involved zero-tillage, no fertilization, and no rainwater harvesting. The collected datasets were analyzed using R, SPSS 15, and spreadsheets. The results showed significant differences in plant indices and soil moisture content among the treatments. However, the treatments had insignificant effects on seasonal actual crop evapotranspiration (ETa), which ranged from 1.93 to 3.29 mm day-1. The interactions between SR and RWH were found to have significant impacts on water use. The Bagging algorithm revealed that the variability in ETa could be attributed to SR (42%), RWH (31%), and SF (26%), respectively. The implementation of rainwater harvesting practices resulted in a significant reduction in water usage, saving 86% of the green water used with a water footprint of 0.25 m3 kg-1, compared to 1.7 m3 kg-1 for no adoption of RWH conditions. The water use of rainfed Guinea grass was also found highly sensitive to dry spells. Further detailed studies using multiple-layer models are recommended to gain a better understanding of the non-linear interactions in semi-arid environments.
More than employment: Belonging and boundary construction among immigrants in rural Finland
Authors: Enbuska Marja
Published: June 2024

Rural communities frame immigrants’ belonging experiences in various ways. In this article, I examine: 1) how do immigrants produce belonging in their speech through symbolic boundaries in rural areas, and 2) what kinds of belonging do those boundary constructions create? This study contributes to the discussion about belonging in rural areas by highlighting immigrants’ own voices in the process. The empirical data is based on twenty-three semi-structured interviews of immigrants living in rural areas in Finland. As a conclusion, the interviewees created belonging in relation to the safety and stagnancy of rural places, the experience of being (not) understood, and within religion and value systems. Within these three frames, the interviewees highlighted the meaning of employment, language, and social relations with Finnish people as aspects that promoted their sense of belonging. However, rural areas’ structural order offers different opportunities for these three elements of belonging to materialise.

Abstract. In times of growing concern about the impacts of air pollution across the globe, lower-cost sensor technology is giving the first steps in helping to enhance our understanding and ability to manage air quality issues, particularly in regions without established monitoring networks. While the benefits of greater spatial coverage and real-time measurements that these systems offer are evident, challenges still need to be addressed regarding sensor reliability and data quality. Given the limitations imposed by intellectual property, commercial implementations are often “black boxes”, which represents an extra challenge as it limits end users' understanding of the data production process. In this paper we present an overview of the QUANT (Quantification of Utility of Atmospheric Network Technologies) study, a comprehensive 3-year assessment across a range of urban environments in the United Kingdom, evaluating 43 sensor devices, including 119 gas sensors and 118 particulate matter (PM) sensors, from multiple companies. QUANT stands out as one of the most comprehensive studies of commercial air quality sensor systems carried out to date, encompassing a wide variety of companies in a single evaluation and including two generations of sensor technologies. Integrated into an extensive dataset open to the public, it was designed to provide a long-term evaluation of the precision, accuracy and stability of commercially available sensor systems. To attain a nuanced understanding of sensor performance, we have complemented commonly used single-value metrics (e.g. coefficient of determination, R2; root mean square error, RMSE; mean absolute error, MAE) with visual tools. These include regression plots, relative expanded uncertainty (REU) plots and target plots, enhancing our analysis beyond traditional metrics. This overview discusses the assessment methodology and key findings showcasing the significance of the study. While more comprehensive analyses are reserved for future detailed publications, the results shown here highlight the significant variation between systems, the incidence of corrections made by manufacturers, the effects of relocation to different environments and the long-term behaviour of the systems. Additionally, the importance of accounting for uncertainties associated with reference instruments in sensor evaluations is emphasised. Practical considerations in the application of these sensors in real-world scenarios are also discussed, and potential solutions to end-user data challenges are presented. Offering key information about the sensor systems' capabilities, the QUANT study will serve as a valuable resource for those seeking to implement commercial solutions as complementary tools to tackle air pollution.
Temporal dynamics and environmental controls of carbon dioxide and methane fluxes measured by the eddy covariance method over a boreal river
Authors: Vähä Aki , Vesala Timo , Guseva Sofya , Lindroth Anders , Lorke Andreas , MacIntyre Sally , Mammarella Ivan
Published: June 2024

Abstract. Boreal rivers and streams are significant sources of carbon dioxide (CO2) and methane (CH4) to the atmosphere.  Yet the controls and the magnitude of these emissions remain highly uncertain, as current estimates are mostly based on indirect and discrete flux measurements. In this study, we present and analyse the longest CO2 and the first ever CH4 flux dataset measured by the eddy covariance (EC) technique over a river. The field campaign (KITEX) was carried out during June–October 2018 over the River Kitinen, a large regulated river with a mean annual discharge of 103 m3 s−1 located in northern Finland. The EC system was installed on a floating platform, where the river was 180 m wide and with a maximum depth of 7 m.  The river was on average a source of CO2 and CH4 to the atmosphere. The mean CO2 flux was 0.36 ± 0.31 μmol m−2 s−1 and the highest monthly flux occurred in July. The mean CH4 flux was 3.8 ± 4.1 nmol m−2 s−1 and it was also highest in July. During midday hours in June, the river acted occasionally as a net CO2 sink. In June–August, the nocturnal CO2 flux was higher than the daytime flux. The CH4 flux did not show any statistically significant diurnal variation. Results from a multiple regression analysis show that pattern of daily and weekly mean fluxes of CO2 are largely explained by partial pressure of CO2 in water (pCO2w), photosynthetically active radiation (PAR), water flow velocity and wind speed. Water surface temperature and wind speed were found to be the main drivers of CH4 fluxes.
Updates and evaluation of NOAA’s online-coupled air quality model version 7 (AQMv7) within the Unified Forecast System

Abstract. Air quality forecasting system is an essential tool widely used by environmental managers to mitigate adverse health effects of air pollutants. This work presents the latest development of the next generation regional air quality model (AQM) forecast system within the Unified Forecast System (UFS) framework in the National Oceanic and Atmospheric Administration (NOAA). The UFS air quality model incorporates the U.S. Environmental Protection Agency (EPA)’s Community Multiscale Air Quality (CMAQ) model as its main chemistry component. In this system, CMAQ is integrated as a column model to solve gas and aerosol chemistry while the transport of chemical species is processed by UFS. The current AQM version 7 (AQMv7) is coupled with an earlier version of CMAQ (version 5.2.1). Here we describe the development of the updated AQMv7 by coupling to a ‘state-of-the-science’ CMAQ version 5.4. The updates include improvements in gas and aerosol chemistry, dry deposition processes, and structural changes to the Input/Output (IO) interface, enhancing both computational efficiency and the representation of air-surface exchange processes. A simulation was conducted for the period of August 2023 to assess the effects of these updates on the forecast performance of ozone (O3) and fine particulate matter (PM2.5), two major air pollutants over the continental United States (CONUS). The results show that the updated model demonstrates a significantly enhanced capability in simulating O3 over the CONUS by reducing the positive bias during both day and night, leading to a reduction of the mean bias by 50 % and 72 % for hourly and the maximum daily 8-hour average O3, respectively. Spatially, the updated model lowers the positive bias of hourly O3 in all of the ten EPA regions, particularly within the Great Plains. Similarly, the updates induce uniformly lower fine particulate matter (PM2.5) concentrations across the CONUS domain, reducing the positive bias in the northeast and central Great Plain and exacerbating the negative bias in the west and south. The updated model does not improve model performance for PM2.5 in the vicinity of fire emission sources as compared to AQMv7, thus indicating a focal point of model uncertainty and needed improvement. Despite these challenges, the study highlights the importance of the ongoing refinements for reliable air quality predictions from the UFS-AQM model, which is the future replacement of NOAA’s current operational air quality forecast system.
An updated aerosol simulation in the Community Earth System Model (v2.1.3): dust and marine aerosol emissions and secondary organic aerosol formation

Published: June 2024

Abstract. Aerosols constitute important substance components of the Earth's atmosphere and have a profound influence on climate dynamics, radiative properties, and biogeochemical processes. Here we develop updated emission schemes for dust, sea-salt, and marine primary organic aerosols (MPOA) and augment formation reactions for secondary organic aerosol (SOA) by introducing updated parameterizations within the Community Earth System Model (CESM; version 2.1.3). The modified scheme shifts the original hotspot-like dust emission to a more continuous distribution, improving the dust aerosol optical depth (DAOD) simulations at stations in North Africa and Central Asia. Also, it results in shorter dust residence time, necessary for enhancing concentration simulations downwind of dust source regions. Modifications in the sea-salt emission scheme include an update to sea surface temperature (SST) modulation and the introduction of a relative-humidity-dependent correction factor for sea-salt particle size. The effect of SST is much more significant compared to that of relative humidity. We then extend to incorporate emissions of marine primary organic aerosols (MPOA) as externally mixed with sea-salt aerosols, coupled offline with ocean component Parallel Ocean Program (POP2). The influence of phytoplankton species on modeling MPOA emissions is profound, highlighting the significance of biological diversity in shaping aerosol emissions. In addition to these emission scheme improvements, we also refine the chemical mechanisms in the model. The irreversible aqueous uptake of dicarbonyl compounds is added as a new pathway for the SOA formation in the model. These improvements enrich the capability of the CESM by using ESM’s intricate linkage between different spheres of the Earth system, thereby enabling a more comprehensive description of natural aerosol emission and chemical processes and their impacts.

Abstract. Waves have the potential to increase the power output of a floating wind turbine by forcing its rotor to move against the wind. Starting from this observation, we use four multi-physics models of increasing complexity to investigate the role of waves and platform movements in the energy conversion process of four floating wind turbines of 5–15 MW in the Mediterranean Sea. Progressively adding realism to our simulations, we show that large along-wind rotor movements are needed to increase the power output of a floating wind turbine; however, these are prevented by the current technology of spar and semi-submersible platforms. Wind turbulence is the main cause of power fluctuations for the four floating wind turbines we examined and is preponderant over the effect of platform motions due to waves. In a realistic met-ocean environment, the power curve of the floating wind turbines we studied is lower than that obtained with a fixed foundation, with reductions in the annual energy production of 1.5 %–2.5 %. The lower energy production is mainly ascribed to the platform mean tilt, which reduces the rotor's effective area.

Published: June 2024

The article considers the method of synthesis of an optimal UAV flight path and an algorithm of the flight control system. The system and algorithm are designed for four-dimensional (4D) trajectory-based operations (TBO) in the context of the CNS/ATM and PBN concepts, which will increase the operational efficiency of the UAV navigation and piloting processes. The paper presents a mathematical model of the control object and algorithms for forming a time-optimal flight path. An assessment of the proposed methodology is also presented by verifying and validating the system software using simulation modeling. The results obtained demonstrate the functional capabilities of the control system to create time-optimal profiles of trajectories that meet operational requirements.
AIRCRAFT FLIGHT SAFETY MANAGEMENT SYSTEM WITH A BASIC BUILT-IN SYSTEM OF AUTOMATIC TOLERANCE CONTROL OF THE HYDRAULIC SYSTEM AND FAILURE MONITORING AND FORECASTING SYSTEMS
Authors:   Moscow State Technical University of Civil Aviation, Bobrin Mihail A
Published: June 2024

This paper considers an integrated tolerance control system with failure monitoring and prediction subsystems for aircraft safety management system (ASMS), which is relevant nowadays. The paper deals with the operational component of hydraulic system (HS) tolerance zones. The internal measured parameter is pressure, so it was necessary to find an algorithm that reflects its dependence on operating conditions, its coefficient of kinematic viscosity of the fluid, its temperature, operating time, ambient temperature and flight stage. The operational component of the tolerance zone can be derived from the obtained expression for the pressure by substituting the boundary values of the parameters included in this dependence. While polling the sensors of the automatic control system it is necessary each time to calculate the range of variation of the parameter for the given stage of flight and other conditions with the help of algorithms for calculating the tolerance zone obtained in the paper. Moreover, the control system has to process a large amount of information using artificial intelligence (AI) methods which allows the safety of aircraft flight (SAF) to be managed.

Assessing the technical condition of glazing elements in the cockpits of operational-tactical aircraft still remains the most important task in ensuring flight safety. To increase the efficiency of operations for non-destructive testing of glazing elements using the speckle structure method of optical radiation, the authors propose to use neural network technologies to automatically identify controlled areas in the cockpit. Artificial intelligence technologies have been used to realise this task. They are based on algorithms of semantic segmentation, classification and detection of monitored areas according to the established markers on the cabin due to the application of convolutional neural network on YOLOv8. The application of machine vision technology have made it possible real-time measurement of the glazing exit from the termination when overpressure has been created inside the cabin. This reduces the time for technical condition assessment by at least 10 times. The use of machine vision technologies have made it possible to measure the value of the glazing outlet from the sealing in real time when creating excessive pressure inside the cabin and thereby reduce the time to assess the technical condition by at least 10 times. The authors have established the reason for the discrepancy between the results of using the speckle-structure method of optical radiation in determining the value of glazing yield from the termination and the "tape" method and developed recommendations to reduce measurement errors.

Conflict detection and resolution is one of the key tasks in ensuring the safety and efficiency of air transport. In Trajectory Based Operation (TBO), aircraft are given greater flexibility in planning trajectories along the route and greater responsibility for self-separation from each other, so the pilot will need assistance to safely and efficiently perform the task of decentralized conflict resolution during the en-route flight. In this work, we develop a method for identifying and resolving conflict situations in cruising phase based on four-dimensional grid nodes (4D-grid) and the A-star shortest path search algorithm (A* for short) to form an optimal four-dimensional trajectory (4D-trajectory) bypass all airspace obstacles. This new approach helps to avoid false warnings about potential conflicts due to the ability to early detect them and accurately determine the distance from aircraft to areas of dangerous proximity (prohibited zones (PZ), zones of bad weather, other aircraft) and then autonomously form a time-spatial trajectory to bypass them. In order to demonstrate the effectiveness of the proposed method, we conduct three experiments in different airspace conditions (with and without the areas of dangerous proximity). The results of the experiments prove that potential dangerous proximities of aircraft in flight are effectively identified and resolved using the proposed methodology.

The research program examined previous research into cognitive function during exercise-induced heat strain, explored hormonal contraceptive use and menstrual symptoms in a general population of adult women, assessed the influence of female sex hormones on the reliability of a cognitive battery, and investigated the combined effects of thermal strain, progressive dehydration, and exercise on cognitive performance in naturally menstruating women. The findings of the thesis seek to provide greater insight into conducting female-specific research, particularly within occupational and sporting settings.
The relationship between faith in God, resilience and overall mental health outcomes among university students in Australia
Authors:   , Metry Shereen
Published: June 2024

This study surveyed over 500 university students to investigate whether the meaning of life, hope, and resilience help explain why faith in God affects the mental health of university students, specifically looking at depression, anxiety, and stress. The findings show that believing in God, feeling like life has meaning, and having hope are linked to stronger resilience and fewer mental health problems among university students. These findings suggest that university counselling programs aiming to boost resilience might encourage students to reflect on their beliefs on faith, hope, and the meaning of life to help improve the mental well-being of students.
