Modeling climate change impact on dryland wheat production for increased crop yield in the Free State, South Africa, using GCM projections and the DSSAT model
Authors: Ajilogba Caroline F. , Walker Sue 
Published: July 2023

Introduction: The impact of climate change on food production in South Africa is likely to increase due to low rainfall and frequent droughts, resulting in food insecurity in the future. The use of well-calibrated and validated crop models with climate change data is important for assessing climate change impacts and developing adaptation strategies. In this study, the decision support system for agrotechnology transfer (DSSAT) crop model was used to predict yield using observed and projected climate data.Materials and Methods: Climate, soil, and crop management data were collected from wheat-growing study sites in Bethlehem, South Africa. The DSSAT wheat model (CROPSIM-CERES) used was already calibrated, and validated by Serage et al. (Evaluating Climate Change Adaptation Strategies for Disaster Risk Management: Case Study for Bethlehem Wheat Farmers, South Africa, 2017) using three wheat cultivar coefficients obtained from the cultivar adaptation experiment by the ARC-Small Grain Institute. The model was run with historical climate data for the eastern Free State (Bethlehem) from 1999 to 2018 as the baseline period. To determine the effects of climate change, the crop model simulation for wheat was run with future projections from four Global Climate Models (GCM): BCC-CSM1_1, GFDL-ESM2G, ENSEMBLE, and MIROC from 2020 to 2077.Results: The average wheat yield for the historic climate data was 1145.2 kg/ha and was slightly lower than the highest average yield of 1215.9 kg/ha from GCM ENSEMBLE during Representative concentration pathways (RCP) 2.6, while the lowest yield of 29.8 kg/ha was produced during RCP 8.5 (GCM GFDL-ESM2G). Model GFDL-ESM2G produced low yields (29.8–47.74 kg/ha) during RCP 8.5 and RCP 6.0, respectively. The yield range for GCM BCC-CSM1_1 was 770.2 kg/ha during RCP 2.6 to 921.68 kg/ha during RCP 4.5 and 547.84 kg/ha during RCP 8.5 to 700.22 kg/ha during RCP 2.6 for GCM MIROC.Conclusion: This study showed a declining trend in yield for future climate projections from RCP2.6 to RCP8.5, indicating that the possible impacts of higher temperatures and reduced rainfall in the projected future climate will slightly decrease wheat production in the eastern Free State. Adaptation measures to mitigate the potential impact of climate change could include possible changes in planting dates and cultivars. Using a crop model to simulate the response of crops to variations in weather conditions can be useful to generate advisories for farmers to prevent low yield.

за последние 100–120 лет изучения механизмов возникновения и генерации биопотенциалов мозга, нервов, мышц сложилось твердое убеждение, что биопотенциалы могут описываться в рамках стохастических подходов. Вместе с тем открытие эффекта Еськова–Зинченко (статистической неустойчивости выборок любых параметров гомеостатической системы) существенно подрывает возможности стохастики в электрофизиологии. Отметим, что для описания биопотенциалов мы можем взять в качестве первой фазовой координаты x1 (t) величину этих биопотенциалов, а в качестве второй — x2=dx1/dt — скорость их изменения. В таком двумерном фазовом пространстве состояний мы вводим аналог принципа неопределенности Гейзенберга (на вариационные размахи ∆x1 и ∆x2 ) и тем самым приближаем электрофизиологию к аппарату квантовой механики. В работе представлены различия и сходства между квантовой механикой и электрофизиологией гомеостатических систем. Вместо статистических функций f(x) предлагается рассчитывать параметры псевдоаттракторов в двумерном фазовом пространстве состояний (биопотенциалов) вектора x (t) = (x1,x2)T.
for the last 100-120 years of studying the brain, nerves, muscles biopotential generation they were described as stochastic processes. The discovery of the Eskov–Zinchenko effect (stochastic instability of any homeostatic system sample datasets) makes it impossible to apply stochastic laws to electrophysiology. We can define biopotentials with their magnitude x1 as the first phase coordinate and their variation rate x2=dx1/dt as the second coordinate. In such a 2D phase space, we defined an analog to the famous Heisenberg uncertainly principle (for ∆x1 and ∆x2 variation ranges). We also present the similarities between electrophysiology and quantum mechanics. We suggested to estimate the properties of pseudo-attractors in the 2D phase space of biopotentials (for the x (t) = (x1,x2)T vector) instead of the statistical f(x) functions.
THE CONVECTIVE FLOW OF MAXWELL FLUID DRIVEN BY TWO ROTATING AND SPINNING DISKS
Authors: Singla Tanvi , Sharma Sapna , Kumar Bhuvaneshvar 
Published: July 2023

The present work addresses the axisymmetric flow of Maxwell fluid between two stretchable and rotating disks with porous regime. The influence of velocity slip and convective heat transfer are considered to govern the flow. The energy equation is modeled using Cattaneo-Christov heat flux model. The resulting mass, momentum and energy PDE’s are converted to ODE’s by using the Von Karman similarity transformations. Successive linearization method is implemented for numerical solution. The tangential velocity of the fluid increases with the rotating speed of the disks. The enhancement in the convective heat transfer of lower disc results in the rise of temperature profiles whereas temperature falls with the rise in Biot number of the upper disk.

Published: July 2023

In this study, kiwifruit slices were osmotically dehydrated in different hypertonic sucrose solutions and assisted with or without ultrasound. Sucrose concentrations (in three levels of 20, 30, and 40 °Brix), sonication power (in three levels of 0, 75 W, and 150 W), and treatment time (in 8 time intervals: 10, 20, 30, 40, 50, 60, 70, and 80 min) were the factors investigated concerning colour parameters including a* (redness: green to red), b* (yellowness: blue to yellow), L* (lightness), and ?E (total colour difference), and also surface area changes of the kiwifruit slices during osmotic dehydration (OD). As the sonication power (40 kHz) increased from 0W to 150W, the lightness index values of kiwifruit slices reduced from 64.8 to 60.6 (30°Brix). Also, with increasing sucrose solution concentration from 20°Brix to 40°Brix the lightness index values of kiwifruit slices decreased from 61.8 to 59.3 (power=150W). The results showed that the mean of ?E index values of dehydrated kiwifruit slices increased during OD period. The highest ?E index (8.03) and lowest surface area (8.64 cm2) values were for the kiwifruit slices treated by the lowest ultrasound power (0W) and the highest sucrose solution (40°Brix). The average surface area of fresh kiwifruit slices, dehydrated samples, hot-air drying samples, and rehydrated samples were 9.50 cm2, 9.05 cm2, 6.44 cm2, and 7.82 cm2, respectively. The results illustrated that the MMF (Morgan-Mercer-Flodin) equation was the best equation to explain the ?E index changes of untreated and treated kiwifruit slices during OD (the average R2=0.995, the average SSE=0.171, and the average RMSE=0.177).

AbstractBackgroundSkeletal muscle‐secreted myokines widely participate in lipids metabolism through autocrine, paracrine and endocrine actions. The myokines represented by FGF21 and Irisin can promote the browning of adipocytes and serve as promising targets for treating obesity. Although recombinant myokines replacement therapy and AAV (adeno‐associated virus)‐based myokines overexpression have shown a definite effect in ameliorating obesity, novel myokine activation strategies with higher efficacy and safety are still in pressing need. This study aimed to evaluate the therapeutic potential of a novel CRISPR‐based myokines activation strategy in obesity treatments.MethodsIn this study, we used lentivirus and a single AAV vector containing dCas9‐VP64 with a single‐guide RNA to selectively activate Fgf21 and Fndc5 expression in skeletal muscles both in vitro and in vivo. The activation efficacy of the CRISPRa system was determined by qRT‐PCR, Western blotting and ELISA. The treatment effect of CRISPR‐based myokines activation was tested in 3T3‐L1‐derived adipocytes and diet‐induced obese (DIO) mice (male C57BL/6 mice, induced at 6‐week‐old for 10 weeks).ResultsThe virus upregulates myokines expression in both mRNA and protein levels of muscle cells in vitro and in vivo. Myokines secreted by muscle cells promoted browning of 3T3‐L1‐derived adipocytes. In vivo activation of myokines by AAVs can reduce body weight and fat mass, increase the adipocytes browning and improve glucose tolerance and insulin sensitivity in DIO mice.ConclusionsOur study provides a novel CRISPR‐based myokines activation strategy that can ameliorate obesity by promoting adipocytes browning.
Values and Laws

Published: July 2023

AbstractHuman rights and the rule of law are integral to value debates in Europe. But value debates are rarely connected with discourses about the law and legal practice. So far, we know only little of the role of value concepts in legal discourse and how personal attitudes and value conceptions shape legal practice. This chapter aims to show how legal debates and conflicts provide us with the chance to understand the circumstances and contingencies of value and norm creation.
Solidarity: A European Value?
Authors: Quandt Markus , Lomazzi Vera 
Published: July 2023

AbstractSolidarity is considered essential for the sustainability of societies, both at the level of individual contributions to society and as an aspect of cooperation between countries. As such, solidarity is often called upon by politicians in a declarative way. In contrast to most prior work, we investigate an attitudinal perspective on solidarity, not behavioural or policy-preference perspectives. We look at questions such as the prevalence of solidarity attitudes among European populations, the degree to which the declared norm is shared among these populations, and whether solidarity attitudes have changed with consecutive crises in Europe. We also discuss possible antecedents of solidarity levels. Distinguishing solidarity by close and universal scopes, we find that both are associated with the identification of citizens with communities at different levels. In country and time comparisons, European societies display a good degree of homogeneity and stability. Close solidarity is more pronounced than universal solidarity, and this may have even increased over consecutive crises. There are clear differences in relation to socio-historical region, but only modest associations with the religious composition of countries in terms of denominations. One role of religiosity might be that of an identity marker, where more heterogeneity comes with lower levels of solidarity.
A Novel Ship Domain-oriented Parameter of Ship Collision Risk Considering the Ship Maneuverability and Encounter Situation
Authors: Yang Tianyu , Wang Xin , Liu Zhengjiang 
Published: July 2023

AbstractThe identification of ship collision risks is an important element in maritime safety and management. The concept of the ship domain has also been studied and developed since it was proposed. Considering the existing trend that the ship domain is increasingly widely used in collision risk-related research, a new domain-oriented collision risk factor, i.e., the current state of domain (CSD), is introduced in this paper, which can effectively reflect the current state and show a certain predictability of collision risk from the perspective of the ship domain. To further prove the rationality of the CSD, a series of different simulations consisting of three typical encounter scenarios were conducted, verifying the superiority of the proposed parameter.
