Objective: To evaluate the ameliorating effects of Raphanus sativus leaves(RSL)against sodium arsenite(Sa)-induced adverse effects through mice experiments.Methods: Swiss albino mice were divided into four equal groups: control, Sa, RSL,RSL + Sa. Sa(10 mg/kg body weight/day), and powder form of RSL(50 mg/kg body weight/day) were provided as food supplement orallty. Blood indices were measured using commercially available kits through colorimetric methods.Results: It was observed that lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase activities were significantly(P < 0.05)higher in Sa-treated mice than those in the control group. RSL significantly reduced Sainduced elevation of the activities of these enzymes in serum significantly(P < 0.05).Serum butyrylcholinesterase activity and high density lipoproteins cholesterol levels in Satreated mice were significantly(P < 0.05) lower than the control group, and the food supplementation of RSL could significantly(P < 0.05) prevent the reduction of Sa-mediated serum butyryl cholinesterase activity and high density lipoproteins cholesterol levels. RSL could also reduce the Sa-induced elevation of serum urea level significantly(P < 0.05).Conclusions: Results of this study suggest the protective or ameliorating effects of RSL on Sa-induced perturbation of blood indices are related to the hepatic, cardiovascular and kidney dysfunction. Therefore, RSL may be useful to reduce arsenic toxicity in human in the future. 展开更多

We chose a definition of heatwaves (HWs) that has ~4-year recurrence frequency at world hot spots. We first examined the 1940-2022 HWs climatology and trends in lifespan, severity, spatial extent, and recurrence frequency. HWs are becoming more frequent and more severe for extratropical mid- and low-latitudes. To euphemize HWs, we here propose a novel clean energy-tapping concept that utilizes the available nano-technology, micro-meteorology knowledge of temperature distribution within/without buildings, and radiative properties of earth atmosphere. The key points for a practical electricity generation scheme from HWs are defogging, insulation, and minimizing the absorption of infrared downward radiation at the cold legs of the thermoelectric generators. One sample realization is presented which, through relay with existing photovoltaic devices, provides all-day electricity supply sufficient for providing air conditioning requirement for a residence (~2000-watt throughput). The provision of power to air conditioning systems, usually imposes a significant stress on traditional city power grids during heatwaves. 展开更多

It is imperative to choose some low cost, available and effective ameliorants to correct soil acidity in southern China for sustainable agriculture. The present investigation dealt with the possible role of industrial byproducts, i.e., coal fly ash (CFA), alkaline slag (AS), red mud (RM) and phosphogypsum (PG) in correcting acidity and aluminum (Al) toxicity of soils under tea plantation using an indoor incubation experiment. Results indicated that CFA, AS and RM increased soil pH, while PG decreased the pHs of an Ultisol and an Alfisol. The increment of soil pH followed the order of RM 〉 AS 〉 CFA. All the industrial byproducts invariably decreased exchangeable Al and hence increased exchangeable Ca, Mg, K and Na and effective cation exchange capacity. RM, AS and lime decreased total soluble Al, exchangeable Al and organically bound Al. Formation and retention of hydroxyl-Al polymers were the principal mechanism through which Al phytotoxicity was alleviated by application of these amendments. In addition, the heavy metal contents in the four industrial byproducts constituted a limited environmental hazard in a short time at the rates normally used in agriculture. Therefore, the short-term use of the byproducts, especially AS and RM, as amendments for soil acidity and AI toxicity in acid soils may be a potential alternative to the traditional use of mined gypsum and lime. 展开更多

This paper is related to the advancement of the inventory models for ameliorating items and focused on the real-life business situation as with the time the deterioration rate of ameliorating items is increased.In the global world,every supply chain entities as suppliers/manufacturers/retailers want to increase the consumption of their goods without any losses.For this,he/she tries to lure manufacturer/retailers by offering some discounts,i.e.credit period for settling the account.The problem states that the manufacturer purchases the ameliorating items from the supplier,where the supplier offers his/her credit period to settle the account.The manufacturer purchases ameliorating items(like pigs,fishes,ducklings,etc.)and take those items as rawmaterial;when the livestock matures the manufacturer sells it to the retailer and offer credit time for settling the account.Reason to propose the model is when the quantities of livestock become larger,then the manufacturer faces difficulty in maintaining all the livestock.In such a situation,the traditional method(without offering credit period)fails to provide the maximum profit to the manufacturer.Therefore,in order to get maximum profit,the manufacturer needs some more realistic scientific outlook for making decisions.The proposed model provides a more realistic assumption of business markets,by offering credit policy.In the introduced model,manufacturer faces amelioration and deterioration rate simultaneously due to the growth and the death of livestock.The amelioration and deterioration rates are assumed as theWeibull distribution type.Shortages allowed only for the retailer,which is partially backlogged.The main goal of this paper is to minimize the total relevant inventory cost for both the manufacturer and the retailers,by finding the optimal replenishment policy.Themathematical formulation with optimal solutions for manufacturer and retailers are given.Convexity and existence of the proposed model via numerical examples and graphical representations are explained.Finally,the conclusions with some future research direction are discussed. 展开更多

Pyroptosis plays an important role in hemorrhagic stroke.Excessive endoplasmic reticulum stress can cause endoplasmic reticulum dysfunction and cellular pyroptosis by regulating the nucleotide-binding oligomerization domain and leucine-rich repeat pyrin domain-containing protein 3(NLRP3)pathway.However,the relationship between pyroptosis and endoplasmic reticulum stress after intraventricular hemorrhage is unclear.In this study,we established a mouse model of intraventricular hemorrhage and found pyroptosis and endoplasmic reticulum stress in brain tissue.Intraperitoneal injection of the selective GPR120 agonist TUG-891 inhibited endoplasmic reticulum stress,pyroptosis,and inflammation and protected neurons.The neuroprotective effect of TUG-891 appears related to inhibition of endoplasmic reticulum stress and pyroptosis activation. 展开更多

Amelioration of saline-sodic soils through land preparation with three tillage implements (disc plow, rotavator and cultivator) each followed by application of sulfuric acid at 20% of gypsum (CaSO4-2H2O) requirement or no sulfuric acid application during crop growth period was evaluated in a field study for 2.5 years at three sites, i.e., Jhottianwala, Gabrika (Thabal), and Thatta Langar, in Tehsil Pindi Bhattian, Hafizahad District, Pakistan. Within 2.5 years, there was a decrease in the salinity parameters measured (electrical conductivity, pH, and sodium adsorption ratio), with a gradual increase in rice and wheat grain yields. It was observed that the disc plow, which not only ensured favorable yields but also helped improve soil health at all the three sites, was the most effective tillage implement. Also, application of sulfuric acid resulted in higher yields and promoted rapid amelioration of the saline-sodic soils. 展开更多

Large areas of Artemisia ordosica Krasch., Caragana korshinskii Kom., and Caragana intermedia Kuang and H. C. Fu plantations were established on moving sand dunes in the Gonghe Basin (northeastern Tibetan Plateau) for vegetation restoration. Elevating our understanding of the changes in soil characteristics after the establishment of different plantation types can be useful in the context of combating deserdfication. To assess the effects of these plantation types on the restoration of sandy land, we measured soil physical-chemical properties at four depths (0-5, 5-10, 10-20, and 20-50 cm) in each of the three plantation types and also in non-vegetated moving sand dunes (as control sites). Generally, the establishment of A. ordosica, C korshinskii and C intermedia plantations on sand dunes has greatly ameliorated soil quality in the Gonghe Basin. Specifically, relative to the moving sand dunes, shrub plantation has increased the silt and clay contents, total porosity and water holding capacity, soil organic matter, total nitrogen, total phosphorus and total potassium contents. The calculated soil quality index suggested that in the Gonghe Basin, C. intermedia is the best choice for soil amelioration. In all the three plantation types, soil amelioration mainly occurred in the shallow depths. 展开更多

The safe recycling of fly ash (FA) and sewage sludge (SS) in the agricultural processes comprises an important environmental technology on waste management. Soils amended with FA and SS may change their ability to adsorb heavy metals due to either increase of soil pH or decomposition of sludge-borne organic matter. Thus, Cd and Pb sorption was investigated by 1-month incubation under soil moisture content at field capacity and room temperature with an acidic Typic Haploxeroalf from central Greece amended with varying amounts of FA and SS. Batch experiments were conducted by equilibrating the soil samples with CaCl2 solutions containing 0-400 mg Pb L-1 or 0-100 mg Cd L-1. The results showed that the Freundlich equation described well the Cd and Pb sorption. Distribution coefficient (Kd) values of Pb were higher than those of Cd in all the treatments of this study. Application of FA increased Kd values for Cd and Pb to 8.2 and 2.3 times more than the controls, respectively. Simultaneous applications of FA and SS caused a Kd increase of 3.8 and 2.1 times compared to the treatments that received only SS for Cd and Pb, respectively. Treatment of SS alone did not significantly change Cd and Pb sorption compared to the controls. The sorption reactions seemed to be mainly affected by soil pH, which was revealed by the significant correlations of Cd and Pb sorption with soil pH. These suggested that fly ash was very useful as a low-cost adsorbent for Cd and Pb and could be used as an ameliorant for biosolid-amended acidic soils. 展开更多

Some environmental problems, especially soil salinity hinder the regional sustainable development of eastern China coastal region. Salinity mainly comes from tide weave, seawater flooding and seawater intrusion. Over exploitation of groundwater, which is the result of unfitful land use systems, leads to seawater intrusion and salt concentration increase. Agroforestry systems can enrich soil fertility and prevent soil salinization, furthermore help maintain biodiversity and enhance productivity. For the intergrated multiple ecosystems the most critical issue is to select optimum tree species and rationally arrange these plants. The basics of this multiple ecosystem is that different plants will occupy variable ecological niches within an area, both in space and in soil depth. Shelterbelts and trees intercropping with agricultural crops are major types of the multiple ecosystem. Shelterbelts can reduce wind speed and consequently lessen evaporation and erosion of the soil, increase pasture growth by up to 60% on exposed sites, increase crop yields by up to 25%. Besides intercropping with jujube, other agroforestry multiple ecosystem such as forestry plus agriculture, forestry plus agriculture plus fishery, and forestry plus animal husbandry are the most appropriate ways to utilise land resource in this region. 展开更多

In order to ameliorate saline-alkaline soil, EM Bokashi has been applied to rice production in conjunction with subdrainage in Ningxia Autonomous Region and Zhejiang Province. The preliminary results can be summarized as follows: EM Bokashi can increase soil organic matter content, improve soil porosity and permeability, and raise the soil's levels of available nutrients; and EM Bokashi combined with subdrainage treatment is more effective in controlling secondary soil salinization and raising the grain yield and quality than other treatments. The results suggest that EM Bokashi can reduce the necessary amount of chemical fertilizer application, thereby improving the agricultural environment, and that the introduction of EM Bokashi into systems of secondary soil salinization control systems has resulted in significant benefits. 展开更多

A long-term field study was initiated during 1995 at Central Soil Salinity Research Institute, Regional Research Station, Lucknow (26047'58" N and 80°46'24" E) to analyze the effect of agroforestry systems on amelioration of alkali soils. Three agroforestry systems (pas- toral, silvipastoral and silvicultural) were compared with the control where no agroforestry system was introduced. Tree-based silvicultural and silvipastoral systems were characterized by tree species Prosopis juliflora and Acacia nilotica along with grass species Leptochloafusca, Panicum maximum, Trifolium alexandrium and Chloris gayana. Growth of ten-year-old Prosopis juliflora and Acacia nilotica planted in combi- nation with grasses was significantly higher over the silviculture system with the same species. Tree biomass yields of P. juliflora (77.20 t·ha-1) and A. nilotica (63.20 t·ha-1) planted under silvipastoral system were significantly higher than the sole plantation of (64.50 t·ha-1 and 52.75 t·ha-1). Fodder yield under the pastoral system was significantly higher than the silvipastoral system during initial years but it was at par with that of silvipastoral systems after eight years of plantation. The microbial biomass carbon in the soils of silvipastoral systems was significantly higher than in soils under sole plantation of trees and control systems. The Prosopis-based silvipastoral system proved more effective in reduc- ing soil pH, displacing Na+ from the exchange complex, increasing or- ganic carbon and available N, P and K. Improvement in soil physical properties such as bulk density, porosity, soil moisture and infiltration rate was higher in the Prosopis-based silvipastoral system than in the silviculture system or control On the basis of biomass production and improvement in soil health due to tree + grass systems, silvipastoral agroforestry system could be adopted for sustainable reclamation ofhighly alkali soils. 展开更多

Biochar(BC)is widely applied in agricultural production for its multiple uses such as carbon sequestration.However,application of BC alone has limited effect on soil fertility and crop yield,especially alkaline soil.Therefore,a pot experiment on Chinese cabbage(Brassica rapa var.glabra)was carried out in this study to investigate the effect of BC applied with organic fertilizer(OF)on alkaline soil properties and crop yield.To be specific,BC and OF were respectively applied at 0,1%,2%,and 3%,and Chinese cabbage was transplanted and cultivated for 2.5 months.Results showed that BC and OF increased the content of both organic matter and available P in alkaline soil(P<0.05).Moreover,the application of OF alone decreased the pH value but raised available N content of alkaline soil,and the application of only BC demonstrated the contrary effect(P<0.05).OF significantly improved crop yield(P<0.05),but the effect of BC was insignificant.Crop yield was the highest under the treatment of 1%BC and 3%OF.Thus,BC had limited effect on alkaline soil fertility and crop yield,but the application with OF was a good option for ameliorating alkaline soil and raising crop yield. 展开更多
