Published: October 2022

Climate change alters hydrological processes in cold regions. However, the mechanisms of runoff component variation remain obscure. We implemented a WEP-N model to estimate monthly runoff in the Songhua River Basin (SRB) between 1956 and 2018. All flow simulations were accurate (NSE > 0.75 and RE < 5%). The annual runoff was attenuated in 1998, and the hydrological series (1956–2018) was divided into base and change periods in that year. Relative to the BS (base scenario), annual production flow reduction was −28.2% under climate change and water use. A multifactor attribution analysis showed that climate change and water use contributed 77.0% and 23.0% to annual runoff reduction, respectively. Decreases in annual surface and base flow explained 62.1% and 35.7% of annual production flow reduction, respectively. The base flow increased by 8.5% and 6.5% during the freezing and thawing periods, respectively. Relative to the BS, groundwater recharge increased by 9.2% and 4.1% during the freezing and thawing periods, respectively, under climate change conditions. Climate change was the dominant factor attenuating production flow. The change in production flow occurred mainly during the non-freeze-thaw period. The decrease in total production flow in the SRB was caused mainly by the decrease in the surface flow, where the reduction in base flow accounted for a relatively small proportion. Production flow attenuation aggravated water shortages. The utilization rate of groundwater resources is far below the internationally recognized alarm line. Therefore, attention should be directed towards certain areas of the SRB and other regions with minimal groundwater exploitation.

Published: October 2022

The Xiong’an New Area is one of the areas with the richest geothermal resources in the east-central part of China. However, the genesis of the geothermal water in Jixianian carbonate reservoirs in this area is still unclear. This study conducted systematical geochemical and isotopic analyses of the geothermal water in the Jixianian carbonate reservoirs in the Rongcheng geothermal field and summed up the genetic mechanisms of geothermal fluids in deep geothermal reservoirs. The results are as follows: the geothermal water in the study area has a hydrochemical type of Cl·HCO3-Na and originates from meteoric water in the Taihang Mountains. The age of the geothermal water increases from 22 ka in the west to 45 ka in the east, and its transport rate is approximately 1.02 m/a. The Sr concentration and 87Sr/86Sr ratio of the geothermal fluids increase along their runoff direction and are related to the dissolution and filtration of minerals such as dolomite and gypsum and the decay of 87Rb in the Earth’s crust. The geothermal water is involved in deep circulation and occurs in a closed system. These results are consistent with those obtained using the PHREEQC inverse model. The reverse hydrogeochemical simulation results exhibited the precipitation of gypsum and halite, the dissolution of anorthite and quartz, and desulfurization. The geothermal reservoir temperatures were estimated to be 92–113 °C using a SiO2 geothermometer, and the thermal groundwater may have undergone deep circulation, with a prolonged retention time. Moreover, the groundwater occurs in a closed environment, strong water-rock interactions occur between the groundwater and related minerals, and the groundwater absorbs the heat from the deep heat source, thus forming geothermal water.

Published: October 2022

This work presents an empirical and scaling-up study of the degradation and mineralization of amoxicillin (AMX) from expired pharmaceutical formulations by O3-based processes. A set of UV–ozone-based experiments was used to model the kinetics of AMX degradation, considering several chemical/photochemical mechanisms (hydrolysis, direct ozonation, radical reactions, and photolysis). Finally, the modeling data were used for scaling-up purposes, considering CAPEX and OPEX costs on the US Gulf Coast basis. In terms of experimental results, the amoxicillin (AMX) pharmaceutical effluent was successfully degraded by ozone technology at high pH values. The semi-batch ozonation process was effective after 60 min of treatment in all experimental conditions, producing degradation intermediates recalcitrant to O3 oxidative process. From the bench-scale kinetics, scaling-up simulations indicate that the gain provided by adding a UV unit does not compensate for the increase in capital and operational costs of adding irradiation equipment. It suggests ozonation at high pH as the best cost-effective approach to degrade AMX. The figures-of-merit electric energy consumption per order (EEO) corroborates the scaling-up simulations. EEO results indicate no-UV ozonation as the best option to degrade AMX at high pH values. The EEO of the present work showed a lower energy consumption system than previous papers from the literature.

Published: October 2022

A proper management of fresh groundwater lenses in small islands is required in order to avoid or at least limit uncontrolled saltwater intrusion and guarantee the availability of the resource even during drought occurrences. An accurate estimation of the freshwater volume stored in the subsoil is a key step in the water management decision process. This study focused on understanding the hydrogeological system behaviour and on assessing the sustainable use of the groundwater resource in Nauru Atoll Island (Pacific Ocean). A first phase, concerning the hydrogeological characterization of the island, highlighted the occurrence of few drought-resilient freshwater lenses along the seashore. The second part of the study focused on the characterization of a freshwater lens found in the northern coastal area and identified such area as the most suitable for the development of groundwater infrastructures for water withdrawal. The characterization activities allowed quantifying the freshwater lens thickness and volume in order to assess the capability to satisfy the population water demand. A geo-electrical tomography survey was carried out, and a 3D density-dependent numerical model was implemented in SEAWAT. The model results demonstrated that in small islands freshwater can unexpectedly accumulate underground right along the seashore and not in the centre of the island as is commonly believed. Furthermore, the model can constitute a useful tool to manage the groundwater resources and would allow the design of sustainable groundwater exploitation systems, avoiding saltwater intrusion worsening.

Published: October 2022

The braking system is one of the most important components of a vehicle. In general, the brakes will generate heat due to the braking process. The heat generated must be released into the environment to maintain braking performance at optimal conditions. In extreme conditions, braking will fail. The braking system can be developed as a braking support system is a non-contact braking system. One form of the non-contact braking system is the eddy current brake (ECB). ECB is an electric braking system with the principle of eddy current. In the ECB, overheating will result in decreased performance. The approach that can be taken to determine braking performance during heat generation is the modeling process using FEM. This study uses FEM to analyze the heat generated during braking. In addition to using FEM, research was carried out using experiments as a comparison. Analysis of heat generation in braking is needed to determine whether braking with ECB can be a backup and its potential as a substitute for friction brakes. The results show that the ECB heat generation event that affects the temperature rise reduces the braking torque performance. Research indicates that when overheating occurs, braking performance will decrease by up to 10% when the disk surface temperature rises more than 20 °C. It shows the importance of managing heat that occurs in the ECB.

Published: October 2022

The improvement of both the stability and economy of the four in-wheel motor drive (4IWMD) electric vehicle under complex drive cycles is currently a difficult problem in this field. A torque distribution method with the comprehensive goals of optimal torque distribution and energy efficiency, considering economy through energy efficiency for the 4IWMD electric vehicle, is proposed in this paper. Each component of the 4IWMD electric vehicle is modelled. The dynamic programming (DP) control algorithm is utilized for torque distribution between the front and rear in-wheel motors to obtain optimal torque distribution and energy efficiency in the 4IWMD electric vehicle. The simulation is performed on a co-simulation platform with the software of AVL Cruise and MATLAB/Simulink, considering a straight road. Compared to the fuzzy logic control algorithm, the simulation results are very promising, as the energy consumption of the electric vehicle was reduced by 22.68%, 20.73% and 21.84% under the WLTC, NEDC and customized IM240 driving cycle conditions, respectively, with the proposed DP control algorithm. The hardware-in-the loop (HIL) experimental results also indicate that the effectiveness of the proposed DP algorithm is verified under the NEDC, WLTC and IM240 driving cycles, when a straight road is considered. The proposed DP control algorithm not only reduces the vehicle energy consumption and guarantees the optimization of torque distribution, but also increases the driving range of the vehicle.
Novel Machine-Learning-Based Stall Delay Correction Model for Improving Blade Element Momentum Analysis in Wind Turbine Performance Prediction
Authors: Syed Ahmed Kabir Ijaz Fazil , Gajendran Mohan Kumar , Ng E. Y. K. , Mehdizadeh Amirfarhang , Berrouk Abdallah S.
Published: October 2022

Wind turbine blades experience excessive load due to inaccuracies in the prediction of aerodynamic loads by conventional methods during design, leading to structural failure. The blade element momentum (BEM) method is possibly the oldest and best-known design tool for evaluating the aerodynamic performance of wind turbine blades due to its simplicity and short processing time. As the turbine rotates, the aerofoil lift coefficient enhances, notably in the rotor’s inboard section, relative to the value predicted by 2D experimentation or computational fluid dynamics (CFD) for the identical angle of attack; this is induced by centrifugal pumping action and the Coriolis force, thus delaying the occurrence of stall. This rotational effect is regarded as having a significant influence on the rotor blade’s aerodynamic performance, which the BEM method does not capture, as it depends on 2D aerofoil characteristics. Correction models derived from the traditional hard computing mathematical method are used in the BEM predictions to take into account stall delay. Unfortunately, it has been observed from the earlier literature that these models either utterly fail or inaccurately predict the enhancement in lift coefficient due to stall delay. Consequently, this paper proposes a novel stall delay correction model based on the soft computing technique known as symbolic regression for high-level precise aerodynamic performance prediction by the BEM process. In complement to the correction model for the lift coefficient, a preliminary correction model for the drag coefficient is also suggested. The model is engendered from the disparity in 3D and 2D aerofoil coefficients over the blade length for different wind speeds for the NREL Phase VI turbine. The proposed model’s accuracy is evaluated by validating the 3D aerofoil coefficients computed from the experimental results of a second wind turbine known as the MEXICO rotor.

Published: October 2022

Voluntary HIV counselling and testing (VHCT) is a successful intervention for fostering early HIV detection, which is essential for the management of the disease. This study sought to determine the prevalence and factors that influence the utilization of VHCT services among young people. In this study, young people in the Tema Metropolis were cross-sectionally surveyed. The simple random sampling method was used to select the participants. The majority (60%) of the participants were unaware of VHCT, and 83% did not know of any VHCT centre. The majority (72%) of the participants indicated that VHCT was important, and 81% were willing to test for HIV if VHCT services were available in schools. Young people who knew that parental consent was not a requirement during VHCT were about two times more likely to have been tested for HIV (COR = 1.96; 95% CI: 1.05–3.63) compared to their counterparts. Additionally, young people who were willing to test in youth-friendly clinics (AOR = 2.87; 95% CI: 1.09–7.51) had higher odds of testing for HIV compared to their counterparts. The utilisation of VHCT services among young people in Tema was found to be very low. Additionally, young people’s knowledge of VHCT services was below expectations.
Curriculum Proposal for Social Justice Education: A Case Study within High School and College in Japan
Authors: Ozeki-Hayashi Reina , Nakazawa Eisuke , Akabayashi Akira
Published: October 2022

During the COVID-19 pandemic, the socially vulnerable were placed in an even more difficult position. High school and college liberal arts education on social justice is needed to address the possible emerging and re-emerging infectious disease pandemics. A desirable educational curriculum to actualize this should include (1) Basic Theory of Ethics and Social Justice—justice and goodness, justice in Ancient Greece, deontology, utilitarianism, and the principle of inequality—, (2) Social Justice Theories—liberal egalitarianism, communitarianism, and social structural approach, (3) Psychology and Behavioral Economics—social intuitionist model, implicit association test, and nudge—, and (4) Advocacy—racism and xenophobia, elderly, disabilities, women, gender and justice—. The curriculum on social justice aims to help students understand the value of social justice, recognize inequality and disparity in society, and acquire the ability to address the widening social gap and inequality. The concept of justice is internationally diverse. Thus, extracting “social justice” in the context of each country’s culture and adding it to the social justice education curriculum is important.

Published: October 2022

Climate change has contributed to changes in disease transmission. In particular, zoonoses such as tick-borne diseases are occurring in areas previously unsuitable for tick survival, with spread to non-endemic areas rising. Ophthalmic manifestations of tick-borne diseases are rare. Often overlooked, diagnosis requires awareness and a high level of suspicion, which may delay treatment. This review provides a comprehensive overview of ocular disease associated with ticks so that management protocols for patients can be designed and implemented. A narrative literature review was conducted. The current literature includes case series, case reports, and literature reviews. Ocular manifestations of tick-borne diseases include adnexal manifestations, conjunctivitis, keratitis, cranial nerve palsies, optic nerve disease, uveitis, exudative retinal detachment, and panophthalmitis, which may occur in isolation or as part of a systemic process. As there is no one constellation of ocular symptoms and signs diagnostic of tick-borne eye diseases, a systematic approach is recommended with particular attention to significant travel and exposure history. In this review, we identify significant risk factors and propose management strategies for afflicted patients to improve treatment outcomes while maintaining cost-effectiveness. Ophthalmologists and generalists will benefit from increased awareness of ocular manifestations of tick-borne diseases in the age of modern travel and climate change.
Cyprinids as a Valuable Source of Essential Fatty Acids for Human Health: A Review
Authors: STEFFENS W. , WIRTH M.
Published: October 2022

Cyprinids are important objects of world aquaculture production. Many contain high levels of essential fatty acids of the n-6 and especially the n-3 series which have anti­atherosclerotic efficacy. Phytoplankton is the original source of these fatty acids, and the fatty acid composition of the fish is markedly influenced by the lipid pattern of the food. Freshwater fish such as cyprinids are able to desaturate and elongate greater quantities of dietary C 18 n-6 and n-3 polyunsaturated fatty acids (PUFA) to C 20 and C 22 desaturates. Cyprinids feeding on plankton, e. g., silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis), are rich in eicosapentaenoic acid 8.nd docosahexaenoic acid. But lipids of grass carp (Ctenopharyngodon idella) and common carp (Cyprinus carpio) are also characterized by considerable contents of n-3 PUFA. Clinical tests hve proven that consumption of cyprinids has beneficial effects on human health, especially for persons with cardiovascular diseases.
Bioenergetics of Nile Tilapia, Oreochromis niloticus: Effects of Food Ration Size on Metabolic Rate
Authors: XIE S.
Published: October 2022

The metabolic rate of Nile tilapia (Oreochromis niloticus) was determined at 30°C in relatively large respirometers. Fish were fed at five ration levels (2, 4, 6, 8 and 10% body weight per day). The weight of fish ranged from 5.0 to 7.9 g. Both total and feeding (total minus fasting) metabolic rates increased linearly with increased rate of food consumption. As ration increased from 2 to 10%, the proportion of food energy spent in feeding metabo­lism decreased from 32.33 to 16.43%, and that spent in total metabolism decreased from 61.80 to 23.19%.
Observations on the Seed Production of the Tilapia Oreochromis spilurus (Gunther) under Different Spawning Conditions and with Different Sex Ratios
Authors: RIDHA M.T. , CRUZ E.M.
Published: October 2022

Two experiments were conducted to compare the seed production of the tilapia Oreochromis spilurus (Gunther) under ambient and controlled (water temperature of 30.0 :I: 1.0 °C and photoperiod of 14 h day·1) conditions. Twelve 2.0 x 2.0 x 0.5 m fiberglass tanks were used and six tanks were assigned to each spawning condition. In Experiment 1, each tank was stocked with 30 females. Males were added to ob­tain male to female sex ratios of 1:3, 1:4 and 1:5. Each sex ratio in each spawning condi­tion was duplicated and the experiment lasted for 14 months. In Experiment 2, twelve breeders were stockerl per tank at 1:3 male to female sex ratio with two tanks per sex ratio. The experiment lasted for 10 months. In both experiments, seed collection was car­ried out every two weeks. Results showed that sex ratios have no significant effect (P>0.05) on the seed produc­tion of 0. spilurus under both breeding conditions. In both experiments, daily mean seed production under ambient conditions reached its lowest levels during the coldest (Decem­ber-January) and warmest (August) months of the year while, under controlled conditions, it was significantly higher (P<0.05) during the same months. Seed production was more evenly spread throughout the year. No significant difference (P>0.05) was observed in the overall seed composition (eggs, yolk-sac fry and swim-up fry) of females under both breed­ing conditions. The results of this study indicate the potential of extending the restricted six-month spawning season of 0. spilurus in Kuwait to a year with controlled water temperature and light duration.

Authors: BALASUBRAMANIAN C.P. , SUSEELAN C.
Published: October 2022

Reproductive biology of the potentially commercial deepwater crab Charybdis smithii was studied. Samples were obtained during exploratory cruises made in Indian seas by the Fishery Oceanographic Research Vessel Sagar Sampada. Samples were obtained from both pelagic and benthic realms. Five stages of sexual development, namely, immature, early maturing, late maturing, ripe and spent, were distinguished based on morphological and histological examination of the ovary. Size at first maturity at 50% level for females was 48.7 mm carapace width (cw). However, the smallest ovigerous female encountered was 45 mm cw. Individual fecundity was relatively low (1,343-42,209) compared to other brachyuran crabs but eggs were larger. The crab population occupying the pelagic realm was exclusively in non-breeding phase, whereas breeding stock were found only at the bottom.
Effect of Protein Level in Supplemental Diets on the Growth of Cage-Cultured Nile Tilapia in the East Lake, P.R. China
Authors: XIE S.
Published: October 2022

Five diets containing different protein levels from 15.8% to 35.6% were fed to Nile tilapia (Oreochromis niloticus) reared in net cages in the eutrophic East Lake in Wuhan, Hubei, P.R. China, to investigate the protein requirement in the supplemental diet. After the 87- day feeding trial, the results shows that specific growth rate of tilapia fed the diets containing 15.8-25.5% and 25.5-36.5% protein were not significantly different. It was suggested that 15.8-25.5% dietary protein in the supplemental diet was sufficient for the optimum growth of cage-cultured tilapia in a eutrophic water body like the East Lake. This requirement is much lower than the level determined from laboratory studies. Fish body dry matter decreased with increased dietary protein levels while crude protein, crude fat, ash or energy content was not significantly affected.

Pengaruh Penerapan IFRS (PSAK 50/55) terhadap Price to Book Value Saham-Saham Perbankan di Indonesia
Authors: Muchlis Muchlis
Published: October 2022

Implementation of IFRS (PSAK 50/55, accounting standards for financial instruments) in the Indonesian banking industry, has changed the assets valuation from historical cost to fair value method, that increases the value of banks' assets. The increase in asset value due to accounting changes, without any increase in economic value banks' assets, may result in a decrease in Price to Book Value (PBV) of banks' stock in Indonesia. This research shows that the implementation of IFRS has caused a decreasing of PBV of banks' stocks in Indonesia, after controlling Return on Equity (ROE), Leverage and Assets Size, the three factors that are previously known for effecting the PBV. Meanwhile, for manufacturing companies, the implementation of IFRS is presumed not to cause a decrease of PBV, because manufacturing companies have a very small portion of financial assets compared to fixed assets. The implementation of IFRS on fixed assets (PSAK 16) still allows manufacturing companies to choose between historical cost and revaluation method in recognizing their fixed assets. This research shows that the implementation of IFRS does not cause decreasing in PBV of manufacturing companies' stock, because many manufacturing companies may still use the previously used historical cost method, instead of moving to the revaluation method.
