It is found from the literature survey that very few comprehensive reviews exist on the Performance and emission characteristics of a diesel engine using isobutanol–diesel fuel blends. Some of the important reviews on fish oil with Isobutonal as an additive, diesel with different percentages blend with Isobutonal, butonal- gasoline blends effects on the combustion process in a SI engine have been reviewed. Different Isobutonal blends with base fuels experimental performances including both diesel engine and gasoline engines have been reviewed. An attempt is being made to identify best performing methods from the literature reviewed; this will be a reference for further research. This paper deals with updated review of the literature on performance and emission analysis with Isobutonal blends with diesel and biodiesel under the resource constrained.

Driven by the desire to probe into the craze for Nigerian video films among youths, this study sets out to investigate the uses to which youths in the conflict-ridden Port Harcourt city put the social and environmental elements that are transmitted by Nigerian video films and the differential levels of gratifications that they derive from these film portrayals. To accomplish this objective, the thrust was on determining the influence of the environment, conflicts, time, setting and the ambience of a youth’s habitation, on video film usage and gratifications. Using the cluster sampling technique, a sample of 500 subjects was drawn from the population of youths across public Senior Secondary Schools and tertiary institutions in Port Harcourt city and Obio-Akpor LGAs of Port Harcourt metropolis, estimated to be over 40, 000, to participate in the study.The data gathered were analyzed with frequency tables and percentages, pie and bar charts, histogram and frequency polygon as well as chi-square. The findings show, among other things, that certain conflict situations in Port Harcourt were expected by the youths to be reflected in home video films; some social and environmental factors informed the preferences of youths in viewing home video films; the most important use and gratification of home video among Port Harcourt youths was entertainment and relaxation; Port Harcourt youths’ most preferred setting and time for watching films were the family and in the evening respectively; the youths’ places of residence determined their views on home video uses and gratifications; and that the setting of the youth’s exposure to films influenced their choice of films. The study concluded that the social milieu, conflict situations and the ambience of the youths’ habitation influenced their exposure to films. It was, therefore, recommended that since youths prefer watching films in the evenings with members of their family, parents and guardians should see these periods of watching films together as an auspicious avenue to propagate socially sanctioned values and proffer strong reasons against their exposing themselves to immoral and criminal transmissions. Key Words: Analysis, Nigerian youths, Social and environmental factors, Differential gratifications, Nigerian video films

The aim of this paper is to study the flow of visco-elastic fluid of Rivlin-Ericksen and Walters type through a porous media bounded by a rectilinear pipe of uniform cross section in the presence of a transverse magnetic field. The flow takes place under the action of transient and periodic pressure gradients. Using integral transform technique, the exact solution for velocities have been obtained in case of visco-elastic Rivlin-Ericksen fluid and Walters fluid. Finally various cases of permeability of the porous media have been discussed for both the fluids.

Wealth is a major factor in any economy in the comity of nations. It is of necessity that TVET (Technical and Vocational Educational and Training) leads in this aspect of harnessing the abundant human resources of a nation. TVET stands for Technical and Vocational Education and Training. In this case, people are offered education, training, vocational and technical skills. This paper therefore examines in details its role in the creation of wealth.

Recently, the synthesis of furoinoxime, furoinhydrazone, furoinphenylhydrazone, furoinsemicarbazone were synthesized by the interactions of furoinbenzoin with hydroxylamine hydrochloride, hydrazine hydrate, phenyl hydrazine and semicarbazide hydrochloride in presence of aqueous sodium hydroxide in DMF-water (80%) medium respectively. The synthesis of furoinbenzoin were carried out by the known literature method. The structure of all the synthesized compounds were justified on the basis of chemical characteristics, elemental and I.R. and NMR spectral analysis. Keywords :- Sodium hydroxide, DMF-water (80%) medium, substituted benzoinoximes, furoinbenzoinoximes.

The adsorption and inhibition efficiency effect of antipyrine derivatives on the c-steel alloy in 1M HCl were investigated using electrochemical techniques (potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM)). The inhibition efficiency of the inhibitors increased with increasing the concentration of the derivatives and increased also with increasing the temperature. Polarization curves revealed that these compounds are chemical type inhibitors. The adsorption of these compounds follows Langmuir adsorption isotherm. Some thermodynamic parameters of activation and adsorption processes were also determined and discussed.
