WINE PRODUCTION FROM AFRICAN STAR APPLE (CHRYSOPHILLUM ALBIDUM) USING SACCHAROMYCES CEREVISIAE TYPE STRAIN ISOLATED FROM PALM WINE

Postharvest losses of our indigenous fruits due to our tropical condition and apparent lack of preservation facilities are worrisome. It therefore becomes germane to produce wines which are more shelf stable from these fruits to reduce economic losses and moreover encourage the growth of wine production industries locally. Production of wine from African star apple (Chysophillum albidum) was carried out using a genetically-identified yeast strain, Saccharomyces cerevisiae-(GPR1 5`RACE 250bp). The results of the cherry fruit juice analysis before fortification showed that the specific gravity was 1.023 ; sugar level of 60Brix and pH of 4.2 while the result of juice analysis after fortification with sucrose sugar was 1.050 specific gravity, 150Brix sugar and pH of 5.1.  The result of the physicochemical analysis of the wine sample showed that the specific gravity, %alcohol (v/v), total acidity (as acetic acid), pH and residual sugar content were 0.9850, 10.5%V/V, 0.07%, 3.8 and 5.50Brix, respectively. The results of bacteriological analysis showed the presence of Lactobacillus and Acetobacter species. The result of the organoleptic evaluation of the wine sample after one-month storage using analysis of variance (ANOVA) of the mean scores at 95% confidence level showed that the appearance and taste of the wine sample ranked more than its aroma and it was generally accepted at 95% confidence level (P ≤ 0.05). The overall results have shown that wine of acceptable qualities can be produced from African star apple fruits especially when fortified with sucrose sugar prior to fermentation.

LEACHING BEHAVIOUR OF NIGERIAN ILMENITE ORE IN ACID MEDIUM (HYDROCHLORIC ACID)

This study was carried out to investigate the effect of hydrochloric acid on the dissolution of titanium present in ilmenite ore. The X-ray diffraction characterization of the ore reveals that it consists of iron, titanium and silicon oxide phases. Alkaline pretreatment of Nigeria ilmenite ore was carried out using 1.5M of sodium hydroxide. Leaching of the pretreated Nigeria ilemnite was carried out using hydrochloric acid (HCl) concentration of 2, 4 and 6moles, leaching temperature of 50,85,100, fixed leaching time of 150 minutes, fixed particle size of <0.5μm and fixed solid-liquid ratio of 0.1g/ml. Leaching of ilmenite ore with hydrochloric acid, the optimum leaching condition for ilmenite ore was at 6 M hydrochloric acid, leaching time of 150 minutes, solid-liquid ratio of 0.1gm/l, particle size of <0.5μm and leaching time of  85 °C, under these conditions, the optimum dissolution of   Ti  81.01% was obtained.

COBALT COPPER PHOSPHATE THIN FILMS FOR HIGH-PERFORMANCE HYBRID SUPERCAPACITORS: THE IMPACT OF COBALT/COPPER VARIATION

In this work, cobalt copper phosphate thin films with a range of Co/Cu compositions are synthesized on a stainless steel (SS) substrate through a simple hydrothermal technique to be utilized as binder-free cathode electrodes in a hybrid supercapacitor. In contrast to conventional asymmetric supercapacitors, the cobalt copper phosphate thin film used as the cathode and reduced graphene oxide (rGO) used as the anode in the aqueous/all-solid-state design offers a wide working potential window of 1.6 V. The aqueous asymmetric device had a maximum specific capacitance of 128 F g-1 at a current density of 1 A g-1 and a power density of 1.65 kW kg-1, and it had an energy density of 45.7 Wh kg-1 and a power density of 1.65 kW kg-1. This is in addition to having an energy density of 45.7 Wh kg-1 and a power density of 1.65 kW kg-1. Furthermore, in a polymer gel (PVA-KOH) electrolyte,  asymmetric supercapacitor device seems to have a specific capacitance of 37 F g-1 at 1 A g-1, an energy density of 13.3 Wh kg-1, and a power density of 1.64 kW kg-1, all of which are significant improvements above previous findings. In addition to its long cyclic life (87 and 84 percent after 6000 cycles, respectively), the solid-state device’s practical demonstration (the lighting of an LED lamp) suggests that cathode materials may be used to develop stable energy storage devices with high energy density in the future.  This discovery paves the way for further research into phosphate-based materials, as a new class of supercapacitor materials, particularly in light of global warming is challenges.

IMPROVING PRODUCTION CAPACITY IN MANUFACTURING COMPANIES USING FAILURE MODES AND EFFECTS ANALYSIS, FMEA

Failure Modes and Effects Analysis (FMEA) is a technique for the systematic analysis of failures. It is a major tool in reliability analysis. FMEA exists in system, process and design. The term failure connotes the frequency of failure occurrence. In this paper, a functional beverages manufacturing company which operates as a brewery is considered. The methodology comprises the analysis criteria, ranking for the occurrence probability, severity and detection of failures. The risk assessment matrix (RAM) was developed to show how severity relates with occurrence. Three-line production plants were considered: Returnable Glass Bottle (RGB) Line One, Poly Ethylene Tricilicate (PET) Line Two and RGB Line Three. Different failure prone units were analyzed. These were, for RGB Lines One and Three, Uncaser, Bottle Transport Conveyor (BTC), Bottle Washer, Filler and Coding Machine. For PET Line Two, BTC, Filler, Coding Machine, Labeler and Shrink Wrapper were analyzed. The Risk Priority Numbers (RPNs) were calculated. The analysis results showed that production capacity in the company can be improved by redesigning its production process in line with the findings especially in accordance with the different values of the RPNs.

It is a flammable liquid with density of about 0.9 g/kg rendering the fuel efficiency in standard diesel engine of 2021 Shevrolet Silverado on the highway at ~35 mpg, and at ~24 mpg driving in the city.  We discuss the potential of the diesel fuel replacement nationally for the truck transportation vehicles and also suitability of its use for the air jets in the airplane transportation.  We have discussed briefly the problem of the air CO2 accumulation, and its solution using our proprietary carbon negative technologies.

SEMANTIC VARIATION BETWEEN NIGERIAN ENGLISH AND BRITISH ENGLISH/AMERICAN ENGLISH

Although the semantic variation in Nigerian English (NigE) is the object of numerous publications, none has based its discussion on entries from dictionaries of Nigerian English. This paper fills this gap by using data from two dictionaries of NigE with the aim of showing that the socio-cultural milieu and experiences of Nigerians influence the meanings of some English words resulting in extension or outright differences in the meanings of some English words as entered in native English dictionaries. The semantic variations affirm that the socio-cultural realities of Nigeria converge against the idea of having the British or the American variety as the standard for measuring Nigerians competence in English. The paper stresses that these semantic variations are marks of creativity, dynamics of socio-cultural acculturation and nativization that result in linguistic variation among varieties of English and awareness and acceptance of the semantic variations in NigE as variant forms would result in

ODUAL AND NEMBE-BRASS RELATIONS IN THE NIGER DELTA; 1850-1996

Abstract

Odual and Nembe-Brass are two ethnic groups in the Niger Delta situated within the Eastern Niger Delta and Northern Niger Delta Fringe of Rivers and Bayelsa states. The two groups have had friendly and hostile economic, political and socio-cultural relations since the pre-colonial era. This paper examined the relationship between Odual and Nembe-Brass from 1850-1996 with emphasis on the impact of the “legitimate trade” and the establishment of Oluasiri settlement on both groups. The relationship between Odual and Nembe people has promoted trade, political ties, marriage contracts, religious interactions, educational activities amongst others. To generate data for the study, the researcher employed the use of primary and secondary sources of information. Oral Information and written documents were generated from the field and libraries. The interdisciplinary approach was also employed and knowledge from other disciplines was used to augment the historical data. In the analysis, the qualitative approach was used and all the materials were cross-examined to ensure validity. The findings revealed that Odual and Nembe-Brass have had long years of relations and that the period between 1850 and 1996 was very significant as it promoted trade between the two groups. The study established that the “legitimate trade” and the establishment of Oluasiri settlement promoted economic, political and socio-cultural ties between the two groups. The study further revealed that Oluasiri settlement has over the years served as a major centre of intergroup relations between the groups but not without disputes. The study recommended peaceful co-existence and harmonious relations devoid of dominance and marginalization between the two groups as a panacea for sustainable development and peace.
