Published: February 2022

This study aims to see the effect of intellectual intelligence and emotional intelligence on employee performance with experience as a moderating variable. This research was conducted at the Public Works Department of Malang City. The type of research used is a quantitative approach research model using data in the form of numbers. The sample used as many as 122 respondents with the technique of taking census research. Two regression tests were carried out; the first was the independent variable test without the moderating variable, the second was carried out on all independent variables and the moderating variable. This study indicates that in the first test simultaneously or partially, all intellectual and emotional intelligence influence employee performance. After being moderated with work experience variables in the second test, intellectual and emotional intelligence variables become insignificant on employee performance. Thus, the moderating variable of work experience is only a moderating predictor variable.

Consistent Multipath Dynamic Source Routing Protocol for Mobile Ad hoc Network
Authors: Lutimath Nagaraj Mallikarjun
Published: February 2022

Mobile Ad hoc Network consists of a large number of mobile nodes that communicate with each other without any infra-structure. Utilizing efficient energy of the nodes and selection of routes from the primary and secondary caches plays an important role. We propose a consistent multipath dynamic source routing protocol (CM-DSR) for mobile ad hoc network by selecting consistent route from cache. The results are simulated using NS-2 simulator. The observations show that our proposed protocol performs better in selection of routes in terms of average residual energy, average transmission per unit time for given density of nodes in the topology, which increases the data transmission from each node to other nodes in the network.

Published: February 2022

Metal Inert Gas welding (MIG) is a widely used welding method for mild steel (low carbon steel) in industry due to its high weld quality, good penetration and comparatively low investment. It is an arc welding process wherein coalescence is produced by heating the job with an electrical arc struck between a filler rod and the job. A Shielding gas (argon, carbon dioxide) is used to avoid atmospheric contamination of the molten weld pool. A filler material is added for joining the work piece by MIG welding. Many researchers investigated on different welding process parameters on mechanical & microstructural characteristics. Some researchers used the welding speed, welding current welding voltage, number of welding passes & work peace thickness for stainless steel, naval grade steel & aluminum. But the shielding gas flow rate & gas mixture also important factor which affects mechanical properties of mild steel. For this study, process parameters such as welding current, gas flow rate and gas combination used in the range 170-210A, 13-17 Lit/min & 0-100 % of CO2 respectively. The material used E-250 grade mild steel with 12 mm thickness. The effect of the welding parameter is investigated by designing the experiments using central composite matrix.

Authors: Chikwado Ugwu Kenneth , Omoruyi A.
Published: February 2022

ABSTRACTThe ethanol extractor was design, fabricated and its performance was evaluated. It comprises of two plastic containers (fermentation and separating tanks) each of which is 41.2 litters in capacity and a steam boiler of 10.6 liters in capacity which was mounted on an electric heater and the temperature was controlled by a thermostat. Aluminum pipe was used to connect the steam boiler by the top side in which gaseous ethanol flows to the water jacket of 15.3 liters in capacity to condense the ethanol to liquid which is collected at the bottom side of the water jacket. Thermometer was mounted on the steam boiler to read the temperature of the mixture inside the steam boiler. Continuous flow of water is ensured in the water jacket to enhance the rate of condensation. The performance test was carried out using four different feed rates of cassava starch at two different durations of extraction which include 500g, 1000g, 1500g and 2000g at 180minutes and 200minutes.  Each one was replicated five times. The results showed that the quantity of alcoholic extracted depends on quantity of starch used. The high the quantity of cassava starch will lead to high durations of extraction that produced high volume of ethanol. The Analysis of Variance (ANOVA) for the effect of feed rates and time on the efficiency of the machine confirms that these factors are important parameters that significantly affect the performance and the volume of ethanol extracted by the machine.

Aspen Hysys simulator was used to determine hydrate formation temperature based on gas field composition and operating pressure by using Peng-Robinson equation. Similar simulations were carried out with the injection of chemical inhibitors such as methanol, ethylene glycol, diethylne glycol and triethylene glycol. The chemical inhibitors prevents hydrate formation by reducing hydrate formation temperature, thereby mitigating against hydrate formation and ensuring constant flow and production of fluid with methanol been the most effective chemical inhibitor based on the hydrate formation temperature reduction trends and analysis.

“Off-shore floating nuclear power plant (OFNP)” is a new concept in the era of secured electric power generation process though the concept of “Floating Nuclear Power Plant” and “Off-shore Power Plant” is not a new concept. We have tried to give a view of the OFNP concept to immune the effect of earthquake, tsunami on the nuclear power plant for Bangladesh. A group of researchers throughout world is also doing project on this. Sitting on two mutual technology:  “light-water nuclear reactors” and “offshore oil and gas drilling platform”, this concept has a lot of aspects to reduce the effect of natural disaster. This concept describes simplified construction, low environmental impact, safety of the nuclear reactor, specialized facility of decommissioning, reliable cooling system, safely transmission of the electric power. As the demand of electricity is increasing in Bangladesh due to increased number of population, the government of Bangladesh is trying to introduce the new mode of electricity generation; Nuclear power. The concept of the OFNP might be best choice in this sector due to different factors and facilities. This paper shows the prospect of OFNP in Bangladesh.

Three geological sediments, namely, the Upper Coal Measures (UCM), the Ajalli Sandstones (AS), and the Lower Coal Measures (LCM), underlie 100% of the landscape of the Idah-Ankpa Plateau (IAP) of the Anambra Basin, Nigeria. The total number of gullies in occurrence on the IAP formation has been estimated at 740, 100, and 1 for AS, UCM and LCM respectively. A total of 34 samples were randomly collected from gully side walls at a depth range of 0 – 15 cm. At sites where gullies did not exist, sampling pits were dug up to a depth of 15 cm within which samples were collected. Fifteen samples were collect from the AS, 14 from the UCM, and 5 from the LCM. Particle size distribution was determined by the hydrometer method, and the dry bulk density was computed from undisturbed cores after weighing, drying at 105oC, and reweighing. The two sets of data were analyzed using descriptive statistics. Results show that the AS had a mean % sand plus %silt = 95, %clay = 5, and a mean dry bulk density = 1.31 g/cm3; the UCM had values of 80, 20, and 1.57 g/cm3; and the LCM 61, 39, and 1.71 g/m3 respectively. The data indicate that the AS sediments are the most prone to detachment and transport, followed by the UCM. Therefore, the vulnerability of the sediments to erosion can be ranked as AS>UCM>LCM, and this can be attributed to their wide variations in particle size distribution and dry bulk density. The findings also agree with the order of proliferation of gullies on the IAP. Activities that trigger accelerated erosion on the AS should be controlled.

Poly vinyl chloride (PVC) is widely used in high and medium voltage cables insulation due to its low dielectric losses and its ability to improve cables properties in high temperatures. This paper aims to improve PVC electrical properties (dielectric strength) for high voltage and medium voltage cables in respect of mechanical characteristics by adding ethylene propylene diene monomer (EPDM). Blends of PVC with EPDM were prepared with 0%, 20%, 35%, 50%, 65%, 80%, and 100% by weight percentages concentration. The dielectric strength of the blends was tested in several conditions such as dry, wet and salty wet condition. Tensile strength test was applied to check mechanical properties of the blends. Results were analyzed using least square method in a way to determine the optimum percentage of mixing PVC/EPDM blend, which gives the best of electrical and mechanical properties under different conditions.

Published: February 2022

The paper examined the use of yam peel to develop an adsorbent material with good surface characteristics for the removal of chromium (vi) from waste water. Activated carbons were produced from yam peel under varying conditions; temperature, time and preparation sequence in order to determine the optimum conditions. It's efficiency on the adsorption of chromium from waste water was investigated through batch adsorption studies using direct reading spectrophotometer. Samples of yam peels, 100g each were carbonized under varying temperatures of 100, 200, 300, 400, and 500ºC ,with varying carbonization time of 20, 30, 40, 50 and 60 minutes. The result revealed that 80% of chromium was removed at 200ºC  and 40 minutes as the optimum carbonization temperature and time respectively. Effect of preparation sequence was equally evaluated, i.e. raw (powdered form), carbonization without activation, activation with (ZnCL2) before carbonization and activation after carbonization with (ZnCL2)  and their adsorbing capacities under an initial concentration of 0.05mg/l were obtained to be 20, 100,100 and 60% respectively. Further increase in concentration results in 100% chromium removal for activation before carbonization and 80% for carbonization without activation. Hence, yam peel activated carbon is recommended for the removal of chromium from wastewater using activation before carbonization procedure at the above optimum conditions.

Published: February 2022

It is well known that rapid growth of population and population augmented industrialization has become a horrible threat for our environment causing the decline of forestry resources. We propose a mathematical model to study the effect of population and population density dependent industrialization on forestry resources. It is assumed that the industrialization grows logistically but its growth is further enhanced due to over population. It is shown that if the population and associated industrialization increase, the density of forestry resources decreases. Numerical simulation has also been conducted to support the analytical findings.

Nigeria has a large number of remote areas that are not being electrified, this is because the power generated is less than the demand of the country. Garundole village is a typical example, with a population of about 270 is not connected to the main grid. Currently load shedding is being practiced by the Power Holding Company of Nigeria (PHCN) to dispatch the power being generated. Moreover, majority of the people leaving in these remote villages depend mostly on diesel power generator. Thus, there is a need to have an independent generating station for such kind of remote village to ease the living conditions of its inhabitants. This paper therefore, reports the economic assessment of PV/diesel/battery hybrid off-grid energy system as an alternative solution to these remote villages. In this regard, three different system configurations is being be studied and analyzed using HOMER optimization software to carry out the economic analysis of the systems and its technical feasibility. The systems include; standalone diesel generator, hybrid PV/diesel with battery storage and hybrid PV/diesel without battery storage.  The result obtained from the study shows that a hybrid PV/diesel with a backup battery has the potential capabilities of replacing diesel powered generator used by individual households independently.
