In Sub-Saharan Africa, effective social landscape governance necessitates a certain amount of social capital, including trust and agreed-upon standards. Climate-smart landscapes are key to successful soil and water management but little effort have been made to critically improve effective soil and water resources. The study was guided by the specific objectives, which include examining equitable climate-smart landscapes and finding out the major challenges facing the implementation of climate-smart landscapes. Using \"landscape governance\" AND \"climate smart landscape,\" 31 papers (31) were obtained from the Web of Science (WOS) and twenty-nine (27) from the Scopus databases using search engines from (1992-2022). On equitable climate-smart landscapes, it was found that multi-stakeholder participation in landscape management is an iterative and changing process that can assist in addressing and resolving disputes as well as facilitating fair negotiation procedures for underrepresented and minority groups. Proper planning and the implementation of a comprehensive planning framework that links various planning activities and decision-making processes are required for landscape approaches to be successful. The major challenges included policies and institutions, financial difficulties in the conservation of natural resources, and socio-economic issues. The novelty from this study is to inform policy makers on climate-smart landscape approaches to ease soil and water management.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"28 5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77950544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Land formation for irrigation face many constraints (ensuring proper slopes, prevention of flood, ensuring canal water command over the field, optimizing earthwork, minimizing truck travel distances, proper equipment utilization). Design engineers traditionally, perform site formation design manually by plane shape, least squire or linear programming methods. Such methods are with different characteristics. The main objective this study is to select and compare performance of these three design methods for proper land leveling design. Consequently, the basic theory of these alternative design methods are reviewed and their performance using data surveyed from five fields in Khartoum North-Sudan, each with different soil surface topographic configurations, is analyzed. The statistical analysis revealed that the linear programming method is the most appropriate design method. Employing the linear programming design method revealed that design slopes in row and cross row directions are within the acceptable range (0.1 to 0.5, the ratio of Cut/fill volumes is within the recommended range (1.1 to 1.3), uniformity of distribution of design elevations of grid points are acceptable and within the target limits (80%), while their deviation is at 80% of grid points around the mean before leveling.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82518747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, a sustainable production flow system, deemed to be effective is proposed in this paper. The production data of each section was collected alongside the manpower and pollution control data. The data were analyzed mathematically using the models developed in this study. From the results obtained, pollution control was least in melting section with pollution control index of 33.8%, and highest in heat treatment with index of 51.9%. Comparatively, pollution control was least (37%) in plant A and highest (50.6%) in plant F. Also, manpower was least (32.4%) in plant A and highest (44.6%) in plant E. Mechanization was least (55.4%) in plant E and highest (73.2%) in plant B. Findings further indicated that melting section was running almost full capacity in Plant E (348 against 350 tons per day) and Heat treatment section was also running almost full capacity (342 against 350 tons per day in Plant C). The rest were running much below their design capacities.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88747735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A completely vacuum opened angle of the device (30°), Six vacuum opening angles (5°, 10°, 15°, 20°, 25° and 30°) and different angles set up on rows (4°, 7°, 10° and 30° through row 1,2,3, and 4, respectively) were separately examined at six rotating speeds. Results revealed that under same speed and same vacuum opening angle, an increase in vacuum provided more consistent rows pick-up, while increase in angle increased rows pick-up coupled with the increase in their variation. Row1 and row4 generally tend to have the highest and lowest seed pick-up, respectively, under most of investigated angles and speeds. Rows consistency CV declined under the increase of both opening angle and velocity. Results of different rows angles set up were found to be better than those of the same angle. Different rows angles resulted in better rows CV value of 2.01%, 1.78%, 1.89%, 1.34%, 1.77% and 2.45% at speed of 5, 10,15,20,25 and 30 r.min-1, respectively.

Besides the concrete material, fiber concrete is applied more popular in the slab foundations. Determining the ultimate load of the slab foundations is a complex problem due to the relation of the soil-structure interaction (SSI) problem, which depends on both the structures and the subsoil characteristics. ANSYS is a finite element software which is a reliable and effective technique to simulate the structure model. This paper aims to determine the ultimate load of the fiber-reinforced concrete slab on the ground subjected to the concentrated load by ANSYS software. The nonlinear material of the structure and the subsoil will be considered in this work. The validation test of the numerical model will be through the experiment data. This study has shown that the numerical model is reliable for the structure design.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73554410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Literature searches were performed using the Science Direct database, Google Scholar search engine, and the professional network ResearchGate using keywords. Land degradation, soil resilience, and natural resources from 2000 to 2019. 120 publications were searched, including journal articles, reports, and book chapters. Of these, 68 were considered more relevant and all were read and considered in writing this review. Climate change, food insecurity, and land degradation have been established to be major challenges for developing countries leading to the loss of genetic diversity. Our results show that the loss of proper habitat may allow fast-growing invaders to occupy the remaining limited resources. Therefore, alien species may accelerate invasion under human-induced land-use changes during times of global change. The time lag between range expansion and habitat loss has been thwarted.

In the first scheme a parallel RL impedance is connected between the supply and the stator coils, in the second scheme a parallel RL impedance is added in the rotor circuit, and in the third scheme the two impedances are connected simultaneously. Transient performance is simulated and the results of the three schemes are compared. Also, the effect of each proposed scheme on the steady state values of the SERD currents, voltages, and electric torque is studied and demonstrated. Lower current and voltage transients, and lower torque oscillations resulted in all schemes, with optimum transient performance observed when adding the two impedances simultaneously.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"58 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72559175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
