This paper reported the marketing of wooden doors in Abeokuta Metropolis. Data were collected through the use of structured Questionnaire administered to the traders in identified locations in Abeokuta metropolis. Descriptive statistics and budgetary techniques were used for the analysis of data collected. The results showed that marketing and trade in this product is male dominated and involved people in their active age of 26-35 years (59%). Majority of the respondents were married and most of them had formal education, at least up to secondary level. Most of the respondents were fulltime marketer and some of the marketer purchase wooden doors from Ijebu-ode and Ibadan at wholesale price. The common wood species used for doors are Gmelina aborea, Tectona grandis, Mansonia altisima, mahogany (khaya spp), Cordia millenii, Nauclea diderrichii. Majority of the respondent started the trade as apprentices. The analysis of cost and returns showed that the marketing of wooden doors is a very profitable business, the rate of returns on investment as a producer was (36.08%) and it was (16.20%) as a wholesaler/retailer. The results of Pearson chi-square showed that age, marital status, other occupations, source of capital, years of experience were the major factors by which variation in monthly profit can be explained and predicted; they were significant at 5% level. It can be concluded from this study that trade in wooden doors is a profitable venture and can provide fulltime employment. However, as the marketers depend on trees planted by the government, they might soon run out of business when the plantations are exhausted. Informed suggestions were offered towards the sustainable management of forest plantation and continued availability of raw materials for production.

Inhibition of C-steel corrosion by metal-organic frameworks containing heterocyclic ligand of Ag (I) in 1 M HCl was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) measurements. The inhibition efficiency increased with increase in inhibitor concentration but decreased with rise in temperature. The thermodynamic parameters of corrosion and adsorption processes were determined and discussed. The adsorption of these inhibitors was found to obey Temkin’s adsorption isotherm. Whereas thermodynamic suggested that a physisorption process occurred.The surface morphology of carbon steel sample was investigated by scanning electron microscopy (SEM).

SHG is the best-root for triggering IGPs in rural and tribal areas and especially areas not properly connected to mainstream living. Coined with the multi-pronged objectives of development and empowerment of weaker section of the society, the strategy and methodology adopted to address the issues are taking care of the need of the marginalized at different economic strata’s through creating enabling environment for addressing the issues. The study is broadly measuring the level and impact of micro credit interventions, functionality and viability of institutions to management the credit, Micro Credit Plans for Self-help Groups as well as the sustainability of the initiatives following a peoples approach.

This paper deals with effect of plants an element of landscape on micro-climate inside aluminum powder producing industry. With the objective to bring micro-climate conditions within or near comfort zone and also create better health condition to benefit health of workers in industry. The experiments were conducted with increase in density of plants in shortlisted experimental area. Identification and adoption of plants with glossy foliage for aluminium powder industry of grade (PAG-4C) is crucial for optimum results. The outcome has shown encouraging results to facilitate architectural intervention towards creating conducive work environment within the industry.

In this paper, a Hybrid approach has been developed by combining Taguchi Method, grey relational analysis method and fuzzy logic, to reap their advantages in the drilling process. Using hybrid approach a single hybrid grade is determined for multiple response characteristics. Drilling experiments has been performed on Al6061 material with coated and uncoated HSS tools under Minimum Quantity Lubrication (MQL) condition. The controllable parameters such as speed, feed, lubricant, tool material and point angle which influence the responses like power, temperature, Burr height, surface roughness are identified. The responses are analyzed using this hybrid approach and optimum controllable parameter combination is identified.

Thermal energy can be stored as latent heat in which energy is stored when a substance changes from one phase to another by either melting or freezing. Paraffin wax has been widely used for latent heat thermal energy storage system applications due to large latent heat and desirable thermal characteristics. Paraffin wax has lower heat transfer rates during melting/freezing processes due to its inherent low thermal conductivity. This paper reviews and summaries the recent experimental and theoretical works on the thermal conductivity enhancement of paraffin wax.
