High corrosion resistance 21%Cr-0.4%Cu ferritic stainless steel contributing to resource conservation

With prices for metal resources such as nickel and molybdenum soaring,there is a heightened sense of crisis concerning resource scarcity.While Type304,the most common stainless steel,offers excellent corrosion resistance,its price is affected significantly by the cost of nickel because of its 8%nickel content.The stainless steel that has the same corrosion resistance as that of Type304 and does not contain nickel and molybdenum has been required.JFE Steel Corporation has developed a new 21%Cr-0.4%Cu stainless steel,the world's first ferritic stainless steel,which offers equivalent corrosion resistance to Type304 while containing absolutely no nickel or molybdenum,two rare metals.The newly developed steel contains 21%chromium with the addition of 0.4% copper.The development of the steel is based on a new discovery that the passive films of stainless steels could be strengthened by the synergy effect of high chromium content and copper addition.Copper addition enriches the chromium content in passive films after field exposure.Newly developed 21%Cr-0.4%Cu stainless steel is adopted for many applications as a substitution for Type304,including commercial kitchenware,building materials and industrial machinery.The steel is expected to be a new standard of a ferritic stainless steel as a substitution for Type304.

Saving Resources for Future Demands-The Role of Instruction,Cognitive Load and Metacognition

Two studies test the hypothesis of conserving resources while performing depleting physical tasks and the modifying role of metacognitive self(MCS).A total of 216 undergraduate students performed two types of physical tasks(a body support on forearms―the first experiment;and a cold water test―the second experiment)in anticipation vs.no anticipation of the future task conditions.Among individuals with high-MCS much weaker persistence could be observed than among those with low-MCS.These results support theories of adaptive goal disengagement suggesting that how individuals apply their resources may stem from other reasons than ego depletion.

The Role of Sports Diplomacy in Advancing Environmental Security in Africa: Case of Forest Conservation in Kenya

Environmental security remains a key challenge in the late 19th through to the 21st century,whose solution has attracted a number of initiatives.Sports diplomacy has achieved great strides in achieving international,regional,and local unity.However,the use of sports diplomacy in achieving environmental security has received much less research attention.This research examines the role of sports in diplomacy in achieving environmental security in Kenya.This study was anchored on the soft power theory and Conservation of Resources(COR)theory which offer frameworks for explaining the role of sports diplomacy in advancing environmental security.The study adopted exploratory research design.The target population was diplomats,marathoners,coaches,environmentalists,conservationists and government officials,academia as well as Water Resources Authority(WRA).The primary data were obtained through open and closed structured questionnaire.The collected data were analyzed through the use of frequency distribution,and thematic analysis.The study established that sports diplomacy advanced environmental security in Kenya,which was better for athletics and volleyball.Environmental security was also enhanced through training,sensitization,conservation efforts,and environmental education.Sport events also allowed a contact-platform for interaction between various groups involved in environment and forest conservation.This study recommends that sports diplomacy should be used in most of the regions in Kenya experiencing environmental perturbations and the current strategies should be applied in the sports diplomacy and environmental conservation as well as security.Further,the government is also encouraged to appoint more sports ambassadors with proper environmental knowledge to help in environmental management.The role of academicians in sports diplomacy and environmental security was found to be minimal where academicians should be at the forefront as the 21st century diplomats are incorporated into sports to be local ambassadors.Perceiving the significance of sports diplomacy and environmental security,there is need for coordination between various county governments to coordinate their efforts and in the process they should bring on board even the non sports actors to boost the role of sports in diplomacy and environment.

Environmental Issues of a Marine Protected Area in a Tectonic Estuary in the Tropical Eastern Pacific:Uramba(Malaga Bay Colombia):Context,Biodiversity,Threats and Challenges

The environmental protection of tropical marine and coastal areas faces different challenges due to the diversity of aspects related to these areas, which include natural, social and economical issues. Despite these challenges, efforts for the protection of these areas are urgent nowadays because of the dramatical increase of human related threats like habitat destruction and population growth. Malaga Bay (MB) is a tectonic estuarine system located in Panama Bight (central region of the Colombian Pacific coast), which due to its origin shows important environmental characteristics of few sites in the Tropical Eastern Pacific (TEP) match. For these reasons, the government of Colombia declared in 2010, the bay’s marine area as a Marine National Natural Park in order to preserve its unique estuarine marine biodiversity. Despite this measure, MB presents several conditions that make environmental protection a very difficult task. In this paper, we present the geographical context, biodiversity and natural resources, environmental threats, the complexity of economic and social context, and the institutional and legal context of MB, to exemplify the difficulty that the protection of marine areas face in the TEP.

Triple bottom-line consideration of sustainable plant disease management:From economic,sociological and ecological perspectives

Plant disease management plays an important role in achieving the sustainable development goals of the United Nations(UN)such as food security,human health,socio-economic improvement,resource conservation and ecological resilience.However,technologies available are often limited due to different interests between producers and society and lacks of proper understanding of economic thresholds and the complex interactions among ecology,productivity and profitability.A comprehensive synergy and conflict evaluation of economic,sociological and ecological effects with technologies,productions and evolutionary principles as main components should be used to guide sustainable disease management that aims to mitigate crop and economic losses in the short term while maintaining functional farm ecosystem in the long term.Consequently,there should be an increased emphasis on technology development,public education and information exchange among governments,researchers,producers and consumers to broaden the options for disease management in the future.

Reduction in COVID-19 related resource loss and decline in prevalence of probable depression in Chinese adults:an application of the Conservation of Resource Theory

Background The levels of resource losses due to coronavirus disease 2019(COVID-19)and mental distress may change during the pandemic period.Based on the Conservation of Resource(COR)Theory,this study investigated such changes and the mediation between survey time(Round 2 versus Round 1)and depression via resource losses.Methods Two serial random population-based telephone surveys interviewed 209 and 458 Hong Kong Chinese adults in April 2020 and May 2021,respectively.Probable depression was defined as 9-item Patient Health Questionnaire(PHQ-9)score≥10.The validated Conservation of Resources Scale for COVID-19(CORS-COVID-19)scale was used to assess resource losses due to COVID-19.Multivariable logistic regression analysis,hierarchical logistic regression analysis,and structural equation modeling(SEM)was conducted to test the association,interaction,and mediation hypotheses,respectively.Results The prevalence of probable depression declined from 8.6%to 1.0%over time,together with reductions in losses of financial resource(Cohen’s d=0.88),future control(Cohen’s d=0.39),social resource(Cohen’s d=0.60),and family resource(Cohen’s d=0.36)due to COVID-19.All the overall scale/subscales of the CORS-COVID-19 were positively and associated with probable depression[adjusted odds ratio(aOR)ranged from 2.72 to 42.30].In SEM,the survey time was negatively associated with the latent variable of resource loss(β=−0.46),which in turn was positively associated with probable depression(β=0.73).In addition,the direct effect of survey time on probable depression was statistically non-significant(β=−0.08),indicating a full mediation effect of resource losses.Conclusions The lessening of the resource losses might have fully accounted for the significant decline in probable depression from Month 3 to 15 since the first COVID-19 outbreak in Hong Kong,China.The level of depression might have increased during the first phase of the pandemic,but might decline in the later phases if resources losses could be lessened.All stakeholders should hence work together to minimize individuals’COVID-19-related resource losses to prevent depression in the general population,as COVID-19 might be lasting.

The centrality of water resources to the realization of Sustainable Development Goals(SDG).A review of potentials and constraints on the African continent

Africa is endowed with vast water resources including but not limited to lakes,rivers,swamps and underground aquifers.However,the way of life in Africa does not reflect this kind of wealth owing majorly to degradation and underutilization of these water resources.This review discusses the centrality of water resources in Africa's pursuit of the Sustainable Development Goals(SDGs).Following the Sustainable Development Model,the paper thematically examines and synthesizes the importance and potentials of water resources to Africa's development through exploring their contributions and limitations to the various economic sectors namely;agricultural and livestock production,energy,manufacturing and processing,tourism,health,fisheries,trade and other institutional mechanisms such as payment for ecosystem services(PES),mutual cooperation and economic cooperation.Data were collected by review of online peer-reviewed and grey literature published between the year 2000 and 2015.It is observed that sustainable management of water and sanitation for all(SDG 6)will be central to the attainment of all the other SDGs(particularly SDG 1(No poverty),2(No hunger),3(Good health),14(life below water)and 15(life on land))across Africa.African states should therefore increase their commitment to water conservation and management as this will significantly decide Africa's future development paths.

Optimization of pelleting parameters for producing composite pellets using agricultural and agro-processing wastes by Taguchi-Grey relational analysis

Agricultural and agro-processing sector produces large stream of by-products that are either discarded or are underutilized.Lignocellulosic biomass especially crop residues’potential to green energy development has been investigated.Material conditions as process variable was made a centerpiece of investigation in the present study since several parameters in the feedstock mixture come into interplay during pelletization.Moisture,binders,blending ratio,particle size,and principle feedstock material were the parameters of our interest in finding their effect on physical and thermochemical characteristics.It is also an endeavor to investigate low cost binder options in producing composite pellets of high quality.A Taguchi L9 orthogonal array experimental design was employed and Taguchi based Grey relational analysis was performed to determine the best combinatorial optimization of factor levels settings for producing best pellets.The optimal parameter level settings for pelletization was determined to be 3.18 mm wheat feedstock material blended with pine shavings at 60/40 ratio.An analysis of variance(ANOVA)was conducted to identify the contribution of each parameter.The magnitude of the significant impacts of parameters on performance characteristics were in the order of binder>blend ratio>grind>feedstock material.Results also showed that the physico-chemical characteristics of the pellets were concomitant with the proportion of ingredients or recipes in a blend.
