Litho-Structural and Metallotectic Context of the Mineralization of the Tondabo Gold Prospect (Brobo, Center of Côte d’Ivoire, West Africa)| Chapter 7 | Current Advances in Geography, Environment and Earth Sciences Vol. 7

 Rhyodacite and mafic volcanics are the principal hosts of achievement mineralization at the Tondabo prospect, which is situated in the northern portion of the Oume-Toumodi-Fettekro greenstone belt (easily upset or inspired lavas and volcanoclastites). These rocks met with a hydrothermal alteration that was characterised by quartz veins and veinlets holding carbonates, sericite, epidote, and sulphide crystals. By silicifying, chloritizing, carbonating, and sericitizing the feldspars, this hydrothermal change brought about a ever-present alteration of the nearby carcasses. Pyrite is governing in the metalliferous paragenesis, but pyrrhotite and chalcopyrite are rare. This mineralization desires that lithological control is present at the Tondabo gold potential. To further appreciate the features of the Tondabo mineralization, our work connects results from lithostructural analysisand gold reasonings. The mineralized deposits are mainly affected by a S1 schistosity familiarize mainly N000-010◦ and youth N040-050◦ with a comprehensive dip of 60◦- 80◦ to the West; however accompanying excellent N-S orientations with a dip of 60◦- 80◦ to the orient. Drilling intervals tell that the quartz-carbonates veins and veinlets that are found in the well deformed zones that comprise local clip zones are associated with the best gold concentrations.

Determination of Poultry Manure on Growth and Fruit Yield of Selected Pepper Species in Nigeria | Chapter 1 | Research Highlights in Agricultural Sciences Vol. 1

 

 The objective of the study is to assess the growth and yield of pepper varieties under different application rates of poultry manure and storage qualities of pepper under different storage structures. The production of pepper is low due to decrease in fertility of soil and inadequate storage structures. Pepper contributes substantially to the Nigerian diet. It is a main constituent of soups and stews. Tatase was reported to contain more minerals than others common peppers in Nigeria. A field experiment was carried out at Department of Agronomy, University of Ibadan between November, 2017 and April, 2018 growing season. Two pepper types (Capsicum annum and Capsicum frutescens) were employed in this study, with four different treatments consisting of various quantities of poultry manure. In a totally randomised design, controls of 0 g of poultry manure (T1), 12.5 g (T2), 25 g (T3), and 37.5 g (T4) were spread out and reproduced four times. In June 2018, a storage experiment was conducted in the Department and at the Nigeria Stored Products Research Institute (NSPRI) in Ibadan. The storage experiment comprised of four treatments with ambient condition (open shelf), wet basket, Evaporative Coolant Structure (ECS/Pot-in-pot), and plastic crates used as storage structures, laid out in a completely randomised design and replicated three times. The physical parameters obtained in days in storage (DIS) included weight loss (%), firmness, freshness, among others. Data observed were subjected to analysis of variance (ANOVA) and means separated using least significant difference (LSD) at p>0.05. The result obtained showed that pepper growth was enhanced using Capsicum frutescens under 25 g poultry manure application rate which resulted to superior pepper yield. Increase in the amount of PM applied significantly improved the crude protein, crude fibre and ash content, but did not influence the dry matter. Poultry Manure did not influence dry matter of pepper for the different levels applied. Within two weeks of storage, the combination of pot-in-pot and sawdust as storage structures improved the storage properties of pepper fruits. Although the various manure treatments had no significant effect on pepper postharvest quality, the ECS can be effectively used in the storage of pepper fruits to improve postharvest quality, lengthen shelf life, and increase the commodity's affordability in all seasons.

Introduction of BIM Methodology in Structural Engineering Education | Chapter 2 | Technological Innovation in Engineering Research Vol. 4

The technique BIM, or building information modelling, has been adopted by the construction industry as a whole. Understanding which components of the project can change with the deployment of BIM is crucial since the structural design is a component of a construction project. There is still considerable opposition to the structural project, which is understandable given the tools for structural assessments and BIM modeling's imperfect compatibility. The research shows how BIM may be used on structural projects to enable the creation of the three necessary sequential stages: the creation of the structural model, the production of the analytical model to conduct the structural analyses, and the detail of the reinforcement. Several readily accessible programmes were utilised to assess the compatibility of BIM systems, including ArchiCAD, ETABS and Revit. The goal of this study is to evaluate the degree of trust in data transmission procedures. This study highlights the primary technique of using BIM-based tools, the primary benefits of using the methodology, and some of the drawbacks mostly brought on by the lack of effective interoperability. The paper outlines the methods used to develop two projects based on actual instances. The purpose of the study is to further the use of BIM in structural projects.
