Abstract. This study explores the potential to retrieve aerosol properties with the GRASP algorithm (Generalized Retrieval of Atmosphere and Surface Properties) using as input measurements of zenith sky radiance (ZSR), which are sky radiances measured in the zenith direction, recorded at four wavelengths by a ZEN-R52 radiometer. To this end, the ZSR measured at 440, 500, 675 and 870 nm by a ZEN-R52 (ZSRZEN), installed in Valladolid (Spain), is employed. This instrument is calibrated intercomparing the signal of each channel with coincident ZSR values simulated (ZSRSIM) at the same wavelengths with a radiative transfer model (RTM). These simulations are carried out using the GRASP forward module as RTM and the aerosol information from a collocated CE318 photometer belonging to the AERONET network (Aerosol and Robotic Network) as input. Dark signal and the signal dependence on temperature are characterized and included in the calibration process. The uncertainties on each channel are quantified by an intercomparison with a collocated CE318 photometer, obtaining lower values for shorter wavelengths; between 3 % for 440 nm and 21 % for 870 nm. The proposed inversion strategy for the aerosol retrieval using the ZSRZEN measurements as input, so-called GRASP-ZEN, assumes the aerosol as an external mixture of five pre calculated aerosol types. A sensitivity analysis is conducted using synthetic ZSRZEN measurements, pointing out that these measurements are sensitive to aerosol load and type. It also assesses that the retrieved aerosol optical depth (AOD) values in general overestimates the reference ones by 0.03, 0.02, 0.02 and 0.01 for 440, 500, 675, 870 nm, respectively. The calibrated ZSRZEN measurements, recorded during two and half years at Valladolid, are inverted by GRASP-ZEN strategy to retrieve some aerosol properties like AOD. The retrieved AOD shows a high correlation with respect independent values obtained from the collocated AERONET CE318 photometer, with a determination coefficient (r2) about 0.86, 0.85, 0.79 and 0.72 for 440, 500, 675 and 870 nm, respectively, and finding uncertainties between 0.02 and 0.03 with respect to the AERONET values. Finally, it is studied the goodness of other retrieved aerosol properties like aerosol volume concentration for total, fine and coarse modes.

Authors: Lewis Clare , Smyth Tim , Neumann Jess , Cloke Hannah
Published: June 2023

Abstract. Atmospherically generated coastal waves labelled as meteotsunami are known to cause destruction, injury and fatality due to their rapid onset and unexpected nature. Unlike other coastal hazards such as tsunami, there exists no standardised means of quantifying this phenomenon which is crucial for understanding shoreline impacts and to enable researchers to establish a shared language and framework for meteotsunami analysis and comparison. In this study, we present a new 5-level Lewis Meteotsunami Intensity Index (LMTI) trialled in the United Kingdom (UK) but designed for global applicability. A comprehensive dataset of meteotsunami events recorded in the UK was utilised and the index's effectiveness was evaluated, with intensity level and spatial distribution of meteotsunami occurrence derived. Results revealed a predominant occurrence of Level 2 moderate intensity meteotsunamis (69 %) in the UK, with distinct hotspots identified in Southwest England and Scotland. Further trial implementation of the LMTI in a global capacity revealed its potential adaptability to other meteotsunami prone regions facilitating the comparison of events and promoting standardisation of assessment methodologies.

Published: June 2023

Abstract. The South China Sea Throughflow (SCSTF) connects the South China Sea (SCS) with neighboring seas and oceans, transferring surface water of the global thermohaline circulation between the Pacific and Indian oceans. A high resolution (4 km, 50 vertical levels) configuration of the SYMPHONIE ocean model is implemented over this region, and a simulation is performed over a 10 year period (2009–2018). An online computation of each term of the water, heat and salt budgets over the SCS (surface, lateral, and river fluxes and internal variations) is moreover developed. Comparisons with in-situ and satellite data show that the model reproduces correctly the spatial and temporal (from seasonal to interannual) variability of the surface water characteristics and circulation over the SCS, and the vertical distribution of water masses. The added value of an online computation compared to an offline one of water, heat and salt budget is quantitatively demonstrated. Important discards are obtained when computing heat and salt lateral fluxes offline (relative bias of respectively 31 % and 52 % and NRMSE of 32 % and 8 %, for the net heat and salt annual fluxes through the SCS). Considerable differences are also obtained for lateral incoming and outgoing fluxes, with relative biases of 41 %, 38 % and 41 % and NRMSE of 352 %, 226 % and 338 % for annual lateral inflows and outflows of water, heat and salt, respectively.
Modelling ice mélange based on the viscous-plastic sea-ice rheology
Authors: Kahl Saskia , Mehlmann Carolin , Notz Dirk
Published: June 2023

Abstract. Ice mélange, which is a mixture of sea ice, bergy bits and icebergs, can have a strong influence on the sea-ice–ocean interaction. So far, ice mélange is not represented in climate models as numerically efficient realizations are missing. This motivates the development of an ice-mélange model based on the viscous-plastic sea-ice rheology, which is currently the most commonly used material law for sea ice in climate models. Starting from the continuum mechanical formulation, we modify the rheology so that icebergs are represented by thick, highly compact pieces of sea ice. These compact pieces of sea ice are held together by a modified tensile strength in the material law. In this framework, the ice mélange is considered as one single fluid, where the icebergs are tracked by a volume in fluid method. Using idealized test cases, we demonstrate that the proposed changes in the material law are crucial to represent icebergs with the viscous-plastic rheology. Similar to the viscous-plastic sea-ice model, the ice-mélange model is highly nonlinear. Solving the model at the resolution needed to represent the typical size of icebergs in ice mélange (< 300 m) is therefore challenging. We show that the ice-mélange formulation can be approximated efficiently with a modified Newton method. Overall, the simple extension of the viscous-plastic sea-ice model is a promising path towards the integration of ice mélange in climate models.

Das neue Volk Gottes in Hispanien. Die Bibel in der christlich-iberischen Historiographie vom 8. bis zum 12. Jahrhundert
Authors: Marschner Patrick S.
Published: June 2023

Mit dem Untergang des Westgotenreiches im Zuge der Umayyadischen Invasion der Iberischen Halbinsel im Jahre 711 begann eine in vielerlei Hinsicht transkulturell geprägte Epoche in Hispanien. Die Araber und später nordafrikanische Dynastien übten eine Fremdherrschaft über weite Teile des früheren Westgotenreiches aus - ein Zustand, den zeitgenössische christliche Autoren auf vielfältige Weise zu verstehen versuchten. Eine Art der geistigen Auseinandersetzung mit dieser Fremdherrschaft offenbart die christliche Geschichtsschreibung, die seit dem achten Jahrhundert in die Spätzeit des Westgotenreiches und die Folgezeit zurückblickte und auf ihre Weise versuchte, die Geschichte zu interpretieren. Die christlichen Chronisten bedienten sich für die Darstellung ihrer Geschichte zahlreicher biblischer Elemente (Zitate, Paraphrasen, Vergleiche etc.). Die vorliegende Arbeit untersucht erstmals die Rolle der Bibel in den christlich-iberischen Chroniken vom achten bis zum zwölften Jahrhundert und leistet so einen Beitrag zum Verständnis der Bibel sowie der Identifikationsstrategien in Bezug auf die kulturell-religiös "Anderen" im transkulturellen Mittelalter der Iberischen Halbinsel.

Published: June 2023

The aim of the work is to analyze the operation of a hybrid heat pump that simultaneously uses the heat of the return network water and outdoor air for heating multi-storey buildings. To achieve this goal, the following tasks are solved: the influence of influences on the temperature of the return network water, air temperature and their compensation on the operation of the product is considered, intermediate circuits at the evaporator and gas cooler are considered for transferring a variable heat load to the heat pump and from the heat pump. The most significant results are the hydraulicaerodynamic scheme of the heat pump, the schemes of the intermediate circuits before the evaporator and the gas cooler. The significance of the results obtained lies in the establishment of such technical solutions for the CHP - heat pumps system, which allow saving gas consumption at the CHP, the cost of heat consumers to pay bills. The use of a working fluid cooler before the gas cooler of the heat pump to control the temperature of the direct network water of the heating system of the building allows you to select such a compressor pressure at which the amount of heat given off by the heat pump to the building will correspond to the temperature curve. In this case, it is desirable to install an air-torefrigerant heat exchanger after the compressor before the gas cooler. It has been established that a PI controller can be used to control the temperature at the outlet of the gas cooler through the inlet air channel.of various parameters, including solar radiation, ambient temperature, compressor speed and initial water temperature, have been simulated and analyzed on the thermal performance of the system.

The growing interest in the world for research on microwave processing technologies of raw materials is shown. It has been established that information in available sources is only about laboratory-scale equipment, and theoretical information (models, mechanisms, calculation methods) is practically absent. The aim of the work is to conduct systematic studies in the “extractor — dehydrator — plant material” scheme. To achieve the goal, these electrodynamical systems are presented with parametric, mathematical, and experimental models. The most significant result of the work is that the concept of a “hybrid” process is introduced to explain the mechanism of interaction between the electromagnetic field and the raw material. Using the first law of thermodynamics, it is shown that the “hybrid” process performs work to move the solution from the volume of the material to its surface. As a result, sluggish diffusion processes are accompanied by powerful flows, the driving force of which is the pressure difference in the capillary of the material and the environment. The importance of the work is that new effects are established: mechanodiffusional and vapordynamical. Mechanodiffusional allows obtaining polyextracts in one extractor, and vapordynamical allows the dehydration of the solid phase in the form of two parallel streams — vapor and juice. Experiments were conducted with rosehip fruits, soybeans, tomato squeezes, and sunflower meal. It is shown that electrodynamical dehydrators are characterized by stable performance indicators of vapor generation up to concentrations of 85°brix, at low levels of energy consumption. The results of chemical studies of the obtained samples in electrodynamical devices are presented.

Published: June 2023

Density functional theory (DFT) is employed to research three carbon tubes (CNTs), SWCNT, N-NiCNT, and N-CoCNT. The first two structures synthesized by other groups and N-NiCNT has better sodium storage properties as sodium-ion battery (SIB) anode than SWCNT, the last one is a designed structure. Here, the intrinsic cause why N-NiCNT has better performance than SWCNT has been located at molecular and atomic levels, meanwhile the potential of N-CoCNT as anode candidate is predicted. The researched properties that determine the electrochemical performances involve in structure stability, frontier molecular orbital, partial density of state analysis, and sodiation barrier comparison. The results indicate that the lower sodiation barrier, expanding transfer space, more stable structure stability of N-NiCNT should be responsible for its better sodium storage performance, which consists with the experimental results. In addition, the designed N-CoCNT anode is a promising candidate as SIB anode owing to better stability, lower barrier, and strong N-Co interaction than N-NiCNT

The reaction of β-dicarbonyl compounds as ethyl acetoacetate with hydrazines is a well-established route for the creation of pyrazole derivatives. In this research, 4-hydrazinoquinazoline (4) reacted with ethyl acetoacetate in boiling ethanol it gives ethyl 3-oxobutanoate quinazolin-4-yl-hydrazone (5). Cyclization of the compound (5) in the presence of glacial acetic acid is passed to form 4-(5-hydroxy-3-methyl-1H-pyrazol-1-yl)quinazoline(6). Furthermore, the reaction of phenylisothiocyanate compounds with hydrazines is a well-established way for the synthesis of tetrazinoquinazoline (8). The new compounds are confirmed by elemental analysis, nuclear magnetic resonance, infrared, and mass spectra. In-vitro anti-tumor evaluation of the new compounds across three cell lines HepG2 (liver carcinoma), HCT-116 (colon carcinoma), and MCF-7 (breast carcinoma) indicats high anti-tumor activity. In addition, antimicrobial activity of specific synthesized compounds are screened against four bacterial species. Amongst four, two Gram-negative are Escherichia coli, Pseudomonas aeuroginosa and gram-positive as Staphylococcus aureus and Bacillus subtilis. The antibacterial activity of Compounds (5) and (6) are greater comparing to standard drug (Amphicillin).

Role of Government in Promoting Real Sector Development in Sub-Saharan Africa: The Nigerian Experience
Authors: M. Thankgod , O. Vivian
Published: June 2023

This paper investigated the role of government in promoting real sector development in sub-Saharan Africa with a focus on the Nigerian economy. The government’s role was measured using fiscal and monetary policy variables such as total government expenditure, broad money supply and interest rate, while the ratio of manufacturing value added to GDP formed the basis for measuring real sector development. Time series data on the variables were sourced from the Central Bank of Nigeria Statistical Bulletin and analysed using econometrics tools of error correction mechanism (ECM) and Granger causality test. The unit root test results revealed that all the variables are first difference stationary. It was also found from the cointegration test that variables have a long-run relationship. It was found from the parsimonious ECM that broad money supply and rate of interest are statistically insignificant in influencing manufacturing output. The results further reveal that the second and third leg of the government expenditure ratio to GDP significantly impacts manufacturing output. 1 percent increase in the first leg of government expenditure increases manufacturing output by 5.962 percent. Similarly, with a percentage in the second lag of government expenditure, manufacturing output increases by 3.182 percent. Additionally, the pairwise Granger causality test results reveal that unidirectional causality flows from the ratio of government expenditure to manufacturing output. Overall, the results indicate that fiscal policy, especially government expenditure, can be relied upon in predicting changes in manufacturing output. Thus, it is recommended for proper monitoring of fiscal policy measures, especially public expenditures, to ensure they are accounted for holistically and effectively utilised in fostering real sector development.

Factors Affecting Access to Healthcare Systems for Children under Five Years with Disability in Low Resource Setting: A Case Study of Wajir County Referral Hospital, Kenya
Authors: L.W. Kivuti-Bitok , N.C. Kiprop
Published: June 2023

Background: Children with disabilities face inequalities in accessing healthcare systems, particularly in low-resource settings. The situation is particularly dire in Kenya, where disability is still widely viewed as a curse or a punishment, and where many traditional healers claim to have the ability to cure disabilities. As a result, many children with disabilities in Kenya frequently have unmet special healthcare needs. Understanding the challenges faced by differently-abled children under five years old in accessing healthcare in low-resource settings is crucial to developing more responsive and effective healthcare systems for this population. Methods: In this hospital-based cross-sectional study, we aimed to investigate the factors affecting access to healthcare for disabled children under five years old in Wajir County, Kenya. We used a simple random sampling technique to recruit 69 caregivers of disabled children, who were interviewed using an interviewer-administered questionnaire. Ethical approval was granted by the KNH/UON Ethical Committee. We used descriptive and inferential statistics, including chi-square tests, to analyze the data using SPSS version 25.0. Results: The majority of the caregivers were women (75.4%). We found that several factors were significantly associated with healthcare accessibility, including the belief that disability was caused by demon possession (p=0.019), reliance on traditional healers for the treatment of disabilities (p=0.034), accessibility of healthcare facilities (p=0.034), distance to the health facility (p=0.042), perceived differential treatment of disabled children (p=0.047), medical costs (p=0.028), lack of access to physiotherapist services (p=0.008), and difficulty in getting appointments suitable for the child (p=0.015). Conclusion: Our findings suggest that children with disabilities in Wajir County face significant barriers in accessing healthcare services, which are compounded by socio-cultural beliefs and economic challenges. A more coordinated, collaborative, and multidisciplinary approach is needed to improve healthcare access for this vulnerable population. Policymakers, healthcare providers, and caregivers should work together to address the identified barriers and ensure that disabled children under five years old have access to the healthcare services they need to thrive.

Classroom practices form an array of integrated teaching and learning strategies conducive to the real world. Lesser is known about the classroom practices experiences among the students belonging to the informal settlements in private schools of India. The paper presents a brief insight into barriers to classroom practices with a self-prepared assessment tool, namely Classroom Practice Position (CPP). It can aid teachers in prioritising practices for balancing participation in the classroom. The measure will help to determine the placement of classroom routine activities. The paper highlights the data from the perspectives of 58 students in Rourkela (a city in the State of Odisha, India) through a sequential exploratory method and data analysis with SPSS v.20. The CPP tool indicates that peer support from the well-performing students helps in mitigating stereotypes, in completion of classwork, identity and familiarity with teachers.

Published: June 2023

The COVID-19 pandemic forced the closure of educational institutions worldwide and put academic schedules in danger. Most educational institutions have turned to online learning platforms to maintain academic activities. But the issues surrounding the readiness, design, and effectiveness of e-learning remain unclear. It is still not precisely understood, especially for a developing nation like India, where technological challenges like device appropriateness and bandwidth availability present significant difficulties. Through an online survey of 152 students, this study aims to investigate how students perceive and enjoy online learning. To create an efficient online learning environment, we also investigated the variables affecting students' motivation levels for online classes. According to the students, while internet connectivity challenges in rural locations make it difficult to take advantage of online learning programs, the flexibility and convenience of online classes make them an appealing option. The insights from this article can help build the curriculum for the new normal in agricultural education systems, where switching totally to online mode may not be practical and a hybrid medium is advised.

However, their career progression in the academic hierarchy appears to be slow. They tend to remain concentrated toward entry-level positions. The present study aims to identify the perceived 'Glass Ceiling' barriers hindering the career advancement of women faculty members at higher education institutions (HEIs). Secondly, this study attempts to find the impact of perceived 'Glass Ceiling' barriers on the career advancement of women faculty members at HEIs. Using a purposive sampling method, responses from 252 women faculty members designated as assistant professors, associate professors, and professors at HEIs of Jaipur City (Rajasthan, India) were collected through a structured questionnaire. Exploratory factor analysis has been applied to identify the 'Glass Ceiling' barriers, followed by a structural equation model using AMOS to study the impact of the barriers on career advancement. The findings of the study exhibit barriers recognized as gender stereotypes, attitudinal aversions, family and organizational factors which create a 'glass ceiling' effect for women and restrict them to rise in their career progression. The identification of multiple barriers offers a substantial contribution to the policymakers of Indian HEIs.

Authors: Tung Nguyen Thanh , Van Luong Van
Published: June 2023

This paper aims to investigate the impact of vehicle velocity on the rollover stability of a fully loaded tractor semi-trailer during lane changes and turning. Specifically, the study focuses on velocities ranging from 30 km/h to 60 km/h. The investigation found that vehicle velocity is a critical parameter that can affect the potential for rollover during lane changes or turning. The results showed that to ensure the vehicle moves steadily and does not roll over during these maneuvers, the steering angle must be controlled and kept within certain limits. The study provided specific recommendations for maximum steering angles at different velocities. For instance, to ensure stability when the vehicle is moving at 60 km/h, the maximum steering angle should be less than 4 degrees. Similarly, at 50 km/h, the maximum steering angle is recommended to be less than 6 degrees, and at 44 km/h, it should be less than 8 degrees. At lower speeds, the recommended maximum steering angle increases, with the maximum recommended angle at 36 km/h being 12 degrees. These findings highlight the importance of carefully controlling vehicle velocity and steering angle to minimize the risk of rollover accidents. By providing specific recommendations for different velocities, this study can inform the design and safety testing of vehicles to improve their stability and safety during lane changes and turning.

This paper describes an experimental program developed to investigate non-bearing spliced composite short column connections made of Glass Fiber Reinforced Polymer (GFRP) that are subjected to axial loading. This study provides aspects such as the load-bearing capacity of the connection, failure modes, load distribution in the connection, displacement in the joint, stiffness, and compressive strength. The design of the joint in this study that connects two 350mm GFRP H-sections to form a short column connection is based on euro codes BS EN 1990 and BS EN 1991, which are used to design steel splicing connections for beams and columns. Four design specifications models are made depending on the positioning of the cover plates in the inner flange, outer flange, and web region of the H-sections to examine the requirement of a specific cover plate, and the H-sections are bolted to each other using M8 8.8 grade steel bolts. The samples tested in this study indicated a dominant failure in the flange region, with model-4 providing 92.83% compressive strength when compared to an uncut GFRP short column.
The Glutamate Dependence Hypothesis May Explain Overeating Browned Food Only and the Worldwide Heart Disease Pandemic
Authors: Cocores James A
Published: June 2023

The following study tried to determine whether Maillard reaction end product-embodied food is significantly more alluring, rewarding, addictive, and cardiovascular taxing than Maillard reaction end product-free meals. As importantly, does Maillard end product-containing fare exhibit more tolerance measured by increased total calorie consumption per day, progression measured by rising amounts of overweight, and withdrawal measured by more frequent urges to snack and dine than Maillard reaction end product-free provisions? The data presented here suggests an intimate association between dietary Maillard-reaction end product-induced glutamate dependence, overeating browned food only, and cardiovascular disease. Phosphorous and glutamate-prompted redox imbalance, hyperlipidemia, immune system activation, chronic inflammatory disease, vascular calcification, hypertension, ischemic heart disease, atrial fibrillation, and stroke may be symptoms of Glutamate dependence.

Published: June 2023

Rise in cost for higher education have been causing less privilege and self-financed students who wanted to further their studies in tertiary education unable to do so due to the less affordability and lack of availability of financial assistance. However, waqf is the most effective ways that have been used to solve the problem. This study aims to examine how universities established their own waqf or endowment fund to help students that are in dire need of financial assistance and at the same time becomes an alternate supply of funds to finance academic activities in university. The study also explained the challenges facing by universities’ waqf bodies. For that, two public universities have been chosen in this study i.e., Universiti Teknologi Malaysia (UTM) and International Islamic University Malaysia (IIUM). This research uses a qualitative approach by applying interviews and library research in the process of collecting data. The finding has shown that waqf undoubtedly offers a great benefit in ensuring the opportunity and access to education at both universities – IIUM and UTM. The challenge, however, is that it requires the continuous societal support in order for it to sustain its operation
