Legal constructed as a tool of social change for the people, especially when the mechanisms of social control other can not function properly, the benefit for the community and provide services that justice so that they can create their order, security and peace (social order), as one of the working device social system, should be able to accommodate the needs of the society. As a means of social control, the law is not only constructed, in development at this time, but the law also constructed as a tool for social change (a tool of social engineering), that the law as a system that has a component substantive (rules) with the conception that looks and structural and cultural components (rules and customs or traditions) provide direct legal function and active as a tool of social engineering that could impose changes in society. Rapid urbanization and unsustainable development process, leading to the city have been greatly influenced by the planning and implementation of urban growth has led to a decrease in urban quality. This occurs in Sawahlunto city is a mining town

Lopatin method of the time-temperature index (TTI) and vitrinite reflectance were used for evaluating the hydrocarbon maturity level in parts of the eastern Niger Delta sedimentary basin. The TTI values were computed from the burial and thermal history of the basin while the vitrinite reflectance was computed from bottom hole temperature logs of oil wells in the area. The time-temperature index analysis was carried out for five horizons; A, B, C, D, and E in the basin. The results show that horizons A and B are immature (TTI < 15). Horizon C has just attained the maturity level (TTI 15) at a depth of 3200 metres. Horizons D and E are mature and are both oil (TTI > 150) and gas (TTI >165) producing. The values of the vitrinite reflectance show that oil generation starts from a depth of about 3000 metres. The results of both TTI and vitrinite reflectance show that hydrocarbon generation start from about 25 Ma upwards. The maturation level obtained from the TTI values agree with that obtained from the vitrinite reflectance.

Analysis of students’ information and their academic records are as important as examination result computation. Out of different computer programs in different tertiary institutions for computing examination results and those published, none of them has proffered the analysis of the multi-level aggregated data of student’s result with some iota of research model to the best of our knowledge. In this paper, students’ result processing software was developed with analysis on the course unit load balancing at the end of an examination period. A deterministic Finite Automata (DFA) mode lis used in the assignment of students ‘grade for each score posted. Personal Home Page Pre-Processor (PHP) with My Structured Query Language (MySQL) were used as programming tools in the development of Students’ Result Processing Software (SRPS). The reports of the students’ result records presented in this paper satisfies the needs of the students, the course advisers, the department, the faculty and the institution. Ultimately, the model employed in this paper provides a more proficient information and analysis for decisions on student(s) records in tertiary institutions.

The inhibitive action of the seed extract of Afzelia Africana on mild Steel corrosion in 2M HCl solutions was investigated using Phytochemical Screening, Weight loss and theoretical analysis. The results obtained at room temperature indicate that the Afzelia Africana seed (AAS) extracts functioned as good corrosion inhibitor in 2M HCl solutions. Inhibition efficiency was found to increase with extracts concentration but decreases with time. The inhibition efficiency increases gradually reaching a maximum value of 86.01% within the first 24 hours after which its inhibitory potency decreases with time. The kinetic study shows that the inhibitory action is a first order kinetics with the concentration of the seed extract of Afzelia Africana which is in tandem with the langmuir adsorption isotherm. Quantum studies revealed that inhibition was due to adsorption of active molecules leading to formation of a protective layer on surface of mild steel. Quantum chemical parameters such as highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO) energy levels, HOMO–LUMO energy gap and electronic density were virtually identified. Quantum analysis demonstrated reactive centres of electrophilic and nucleophilic attack and strong inhibition properties of bioactive molecules of Afzelia Africana seed extract.

This study examined the performance of the mathematics students and microbiology students on three major general studies courses (GST) using the Hotelling’s T2 approach. The objectives of the study includes: to compare the average performance of students in Microbiology and Mathematics departments on general studies courses (GST), to determine the average score of the students on these courses for Microbiology and Mathematics departments, and to ascertain where significant difference exist between the performance of students on these courses for Microbiology and Mathematics departments. The data for the study was secondary data collected from the Examination and Records Department of Imo State University, Imo State, Nigeria. The exam scores of the students were tested for multivariate normality based on skewness and kurtosis. The findings showed that the data obtained were multivariate normally distributed for microbiology and mathematics respectively. Hence, the data satisfies the required assumption to apply a parametric multivariate method such as the Hotelling’s T2 method. The average performance of the two sets of students using their mean scores showed that the Microbiology Department out -performed the Mathematics Department with a mean score of 59.68% across the three GST courses considered in this study. The performances of the two departments on the selected general courses were found to be significantly different assuming a 95% confidence level.

Platonic solids are 3-dimensional solids that have been a subject of interest to mathematician for years due to their natural unique and regular properties. Euclid (300BC) showed that there are only 5 such solids; tetrahedron, cube, octahedron, dodecahedron and icosahedron. Robert moon in the 20th century expanded the link between the platonic solids and the physical world to the electron shell model in chemistry. To delve into this area, this study deals with the action of rotational symmetry groups of the platonic solids on their respective vertices. The action is showed to be transitive, primitive and semi-regular. The sub-degrees of the action of rotational symmetry group of a tetrahedron on its vertices are 1((1))and1((3)). The rank is 2.

Let E be a separable Banach space and S,T:Ω×Y→E be a nonself random commuting mappings defined on arbitrary Y satisfying generalized random φ- contractive-like operator ∥T(ω,x)-T(ω,y)∥≤δ∥S(ω,x)-S(ω,y)∥+φ(∥S(ω,x)-T(ω,x)∥), with T(ω,Y)⊆S(ω,Y) and S(ω,Y) a complete subspace of E,0≤δ<1,φ:R^+→R^+ with φ(t)>0∀t∈(0,∞) and φ(0)=0. It is shown in this paper, that a stochastic version of hybrid iterative algorithm called a modified random Jungck-Mann hybrid iterative algorithm is introduced and is used to approximate the unique common random fixed point of S and T for a generalized random φ-contractive-like operators in a separable Banach space. Strong convergence results for random Picard-Mann, random Picard iterative schemes for single map T are deduced as corollaries. Stability results are proved and an example is provided to demonstrate the applicability of the hybrid scheme.

This experiment was conducted to investigate the effects of priming on regeneration of plantlets and early vegetative growth of a local variety of sweet potato (Ipomoea batatas L). The local variety, Ex-Igbariam, was primed by soaking medium sized cut tubers (12cm x10cm or 100g) in 10% coconut water, 10% orange juice, and in 10% coconut water and 10% orange juice mixture with water as control for 12 hours before planting. Each treatment was replicated three times. The time taken to regenerate plantlets was recorded. Three weeks after planting, single regenerated plantlets were transplanted into perforated plastic containers and “hardened” under sunlight. Six weeks after planting, the number of plantlets, leaves, nodes and vine length were recorded. Data were analysed by analysis of variance (ANOVA) in a completely randomised design (CRD) at P = 0.05 and means were compared by use of the least significant difference (LSD) at P = 0.05. There was no significant difference in time taken for new plantlets to regenerate. Coconut water had significantly higher number of plantlets than other treatments. There were no significant differences in number of leaves, nodes and vine length of plantlets primed with coconut water, orange juice, and the mixture of coconut water and orange Juice. Water (control) produced significantly fewer leaves, nodes and shorter vines than other treatments. This study has shown that cut medium sized tubers primed with 10% coconut water, could double the number of healthy plantlets and thus provide more planting materials for farmers.

Non- wheat composite flour was prepared using yellow maize (YM), soybeans (SB) and jackfruit seed (JF). The ratio of YM:SB:JF was used in the formulation of the flours. The control was 80:20 (sample A), 75:20:5 (sample B), 70:20:10 (sample C), 65:20:15 (sample D), 60:20:20 (sample E), 55:20:25 (sample F). Proximate composition, functional properties, and selected minerals and vitamins, of the flour blends were determined. The proximate composition of flour blends sample showed that the ash content ranged from (1.08-2.05%), moisture (8.89-9.11%), crude fibre (1.10-1.53%) and carbohydrate (69.64-73.72%) respectively. The proximate composition parameters increased significantly (P<0.05) with increasing substitution of the yellow maize flour and soybean flour with jackfruit seed flour with exception of protein content (9.77-7.30%) and fat content (9.52-6.29%) which decreased significantly (P<0.05) with increase in jackfruit seed flour. The functional properties of the flour samples showed that the bulk density varied from 0.57-0.68 g/cm3, viscosity 97.80- 114.67 mPa.S), swelling capacity (6.05-8.84), water absorption capacity (5.09-9.04g/g) and oil absorption capacity (1.36-2.26g/g) respectively. There were significant differences (p <0.05) in all the values. The result of mineral contents of flour blends showed that iron varied from 0.50-0.65, zinc (1.45-3.55mg/100), calcium (4.13-6.67 mg/100), and phosphorus (4.21-8.01 mg/100. The result of vitamins contents of the flour blends showed that Vitamin A ranged from 12.72-24.30 (mg/100), B1 (10.85-16.81mg/100), B2 (4.51- 7.57mg/100) and Vitamin C (80.43- 113.33mg/100). All the vitamins increased with corresponding increase in the level of yellow maize flour and jackfruit seed flour while the soya bean flour remained constant at 20%. The composite flour produced had increased micronutrients and improved functional properties and could be used in food systems including baked and extruded goods.

This study was carried out to ascertain the level of adoption of aquaculture management techniques in Igabi Local Government Area of Kaduna State. Data were collected from 53 respondents in Airforce Base and National Eye Centre fish farming sites in Igabi LGA of the sate by use of a well structured questionnaire. Descriptive statistics such as percentage, frequency distribution, mean and multiple regression analysis were used to analyze the data. It was found that 56.60% of the fish farmers adopted Monoculture, 39.60% of the fish farmers also adopted concrete pond and 35.8% adopted polyculture system. On management of the ponds; liming of pond and pH check, disease treatment, supplmenetary feeding and fertilization of pond had the highest adoption percentage scores that is 62.26%, 50.90%, 49.10% and 41.51% respectively. Weed control, checking pond temperature, use of Net/Siene net, checking of oxygen content recorded low adoption score. None of the eight independent variables showed any significant contribution to adoption of aquaculture techniques using the regression analysis. However, gender, income level, fishing experience, contact with extension agent and number of pond owned positively influenced adoption of aquaculture management techniques in the study area. The major constraints to fish famring were; inadequate credit facilities (64.15%), fish poaching/theft (49.05%)t, fingerling mortality due to poor handling(45.15%), expensive fish feed (45.28%), inadequate fishery extension service (45.28%) and water supply problem (43.39%). The study noted that a key aspect of addressing malnutrition problem in Igabi LGA is the promotion of fish farming as a source of protein. The study also recommended that farmers should form themselves into cooperative society so that they can pool their resources and knowledge together in solving most of the problems identified in this study.

The antibiotic sensitivity profile of bacteria isolated from IyiUba spring water in Udi local government area of Enugu State, Nigeria was investigated. Bacterial species were isolated on Nutrient Agar and a set of selective diagnostic media. The sensitivity of the isolates to 10 different antibiotics selected was ascertained on Muller Hinton Agar using the Kirby- Bauer disc diffusion method. The zone of inhibition of the isolates was measured in mm and the values were interpreted using the Clinical Laboratory Standard International (CLSI). Isolates were identified as Staphylococcus sp, Bacillus sp, Pseudomonas sp, Escherichia coli, Klebsiella sp, Shigella sp and Vibrio sp. The total heterotrophic bacterial count and total coli form count ranged from 4.45±0.07to 5.30±0.00 Log10cfu/ml and 4.35±0.07 to 4.70±0.14Log10cfu/ml respectively. Total Shigella count and Vibriod count ranged from 1.95±2.26a to 4.70±0.00Log10cfu/ml and 1.95±2.76 to 4.90±0.00 Log10cfu/ml respectively. The isolates were resistant to most of the antibiotics used in the study. The highest level of bacteria resistance were as follows; Staphylococcus sp., 100% to Cloxacillin and Cetriaxone, Bacillus sp., 66.67% to Cloxacillin and Erythromycin, Pseudomonas sp., 50% to Chloramphenicol, Cefuroxime and Streptomycin, E. coli 75% to Chloramphenicol, Klebsiella sp., 100% to Chloramphenicol and Streptomycin, Shigella sp., 100% to Amoxicillin, and Vibrio sp., 100% to Cefuroxime. The results showed that the spring water was contaminated and poses a threat to public health. The treatment of the spring water before consumption is therefore advocated. The isolates also exhibited multidrug resistance which poses a great threat to the management of public health.

Aimed at meeting the needs of reservoir simulation, estimates of the wetting phase relative permeability for a sandstone reservoir in the Niger Delta region were made by analysing variables obtained from well logs. Analysis was carried out for two reservoirs (RESERVOIR I and RESERVOIR II), one shallower than the other, within the study area by applying an empirical model (that related relative permeability to fractional water saturation and saturation exponent) to resistivity data obtained from the available well logs. The results showed that the wetting phase relative permeability had estimated values ranging from 0.000 to 0.113 and 0.000 to 0.202, for RESERVOIRS I and II respectively. Further analysis showed that the estimated wetting phase relative permeability was affected by the wettability and pore structure of the reservoirs of interest.

The super alloys having high hardness, toughness and impact resistance are being developed mechanical industry. The super alloys are used in Marine, Aerospace, Nuclear industries etc. Such materials are difficult to be machined by traditional machining process. This paper outlines an experimental study to optimize the process parameters of Wire Electrical Discharge Machining (Wire EDM) for Incoloy 825 super alloy. The objective of optimization is to attain minimum Surface Roughness (Ra) and maximum Material Removal Rate (MRR) individually and simultaneously. In this study, Incoloy 825 super alloy of 20 mm thickness is used as a work piece. Four parameters were chosen as process variables Viz., pulse on time, pulse off time, wire tension, and spark gap voltage. The experiments are conducted based on Taguchi’s L27 orthogonal array (OA), for each experimental run Ra was calculated by using Talysurf, MRR was calculated by using mathematical relationship. The best relationship for process variables were identified by using Grey- Taguchi analysis. By using Genetic algorithm optimization technique the optimal setting is obtained for Ra and MRR individually and finally, Pareto optimal sets are obtained by using NSGA algorithm provides suitable combination of process variables for achieving minimum surface roughness and maximum MRR simultaneously.

The hydrocarbon volume in the Akos field in the Niger Delta has been computed from eight geophysical well logs and depth structural maps. Two reservoirs (A and B)were delineated from the lithology logs. The lithologies observed from the gamma-ray log are sand, shale and sandy shale. The average petrophysical parameters computed for Reservoir A are 28.68%, 43.35%, 30.55% and 253.1797md for porosity, net-to-gross, water saturation, and permeability respectively. Similarly, Reservoir B has an average porosity (24.56%), net-to-gross (44.59%), water saturation (36.65%) and permeability (162.7688 md). Comparing the computed petrophysical properties with standard values, the result shows that both reservoirs have very good porosity, water saturation, permeability and moderate net to gross. The estimated hydrocarbon in Reservoirs A and B are 23.33x106m3 and 72.22x106m3 Stock Tank Barrels (STB) respectively.The results of this study have shown the effectiveness of petrophysical evaluation as a tool for understanding the spatial distribution of reservoir properties and it can be used as a guide for evaluating future performance and production behavior of reservoirs

The effects of different inoculum levels (0, 500, 1000, 1500 egg mass/juveniles) of Meloidogyne javanica on indigenous (Derica) and exotic (F1 Cobra 26) Solanum lycopersicum varieties were studied with the zero (0) group serving as the control. There were 3 replicates of each treatment, laid out in a complete randomized block design. Plants were grown in a screened house using perforated bags. The reproduction rate of the nematodes was monitored at 30 and 60 days after inoculation (DAI). The result obtained from the study showed that there was a significant difference (p<0.05) in the population of M. javanica at 30 and 60 DAI respectively in both cultivars. Both cultivars showed high increase in endophytic nematode population in the 1500 inoculum level (il) 60 DAI. At 60 DAI, F1 Cobra 26 had 400 (44.9%) root nematodes in 1ml of aliquot while the Derica had 370(41.6%) endophytic nematodes. No nematodes were recovered from the roots and soil samples of the control groups 60 DAI. The study also revealed a significant difference (p<0.05) in the root weight of both cultivars as inoculum increased within the 60 day interval. The root weight of Derica cultivar declined as inoculum levels increased from 0 il (14.4g) to 1500 il (13.9g) while the root weight of F1 Cobra 26 increased as inoculum level increased from 0 il (14.2g) to 1500 il (14.6g). There was a significant difference (p<0.05) in the apical growth of both cultivars. At 60 DAI, F1 Cobra 26 cultivar showed more apical competence (90.7cm) than the Derica cultivar (89.8cm) at the treatment groups. The control groups showed the Derica cultivar to have more apical competence than F1 Cobra 26 cultivar 60 DAI.

Aminu et al (2016) defined a Γ1- non deranged permutation group which is a subgroup of symmetric group of prime length. In this paper, we partition Γ1- non deranged permutations (w ∈ ) into its ascent and descent blocks and then define a mapping AI : -> Ω pwhich takes permutation form Γ1- non deranged permutation group to weighted Motzkin path in with respect to both ascent and decent blocks. We then investigate the motzkin polynomial of () An enumeration was formulated for generating Motzkin polynomial of ().

This experiment was conducted to evaluate relationship between flowering of tetraploid maternal (seed) parents and diploid paternal (pollen) parents and the effects on seed set in a polycross mating scheme. The two experimental polycross blocks consisted of four maternal tetraploid plantain hybrids TMPx 2796-5, TMPx 5511-2, TMPx 1658-4 and TMPx 7152-2, and three paternal diploid hybrids TMP2x 2829-62 (plantain), and TMB2x 5105-1 and SH 3362 (bananas). Experimental design was an RCB replicated 2 times. Data collected included time to flowering (TTF), duration of flowering (DOF), synchrony /flowering overlap of paternal and maternal parents, number of bunches and number of seeds of maternal parents over 3 crop cycles. Data were subjected to analysis of variance (ANOVA) and significant effects were tested at P ≥ 0.05. Means were compared using LSD at (P ≥ 0.05). Correlation analysis was used to estimate relationships. There was floral synchrony between some paternal and some maternal parents in the plant crop; in ratoon 1, and in ratoon 2. Flowering overlap occurred between SH3326 plant crop and one maternal parent of ratoon 1. Generally, seed set was highest in ratoon 1 and lowest in ratoon 2. Cumulatively TMPx 2796-5 had significantly (P > 0.05) the highest number of seeds set followed by TMPx 1658-4 with TMPx 7152-2 having the lowest. Significant positive correlations occurred in TTF between maternal TMPx 2796-5 and paternal TMP2 x 2829-62 in ratoon 1; and between TMPx 7152-2 and TMP2x 2829-62 and also between TMPx 7152-2 and SH 3362 in ratoon 2. There was positive significant correlation between TTF of maternal parent TMPx 7152-2 and seed set in ratoon 1. There was positive significant correlation between TTF of paternal TMP2x 2829-62 and seed set of TMPx 7152-2 and between paternal TMB2x 5105-1 and seed set of TMPx 2796-5.

This paper is to study the contributions, analyze the professional handling of patients needs by the globally recognized European, non governmental organization Médecins Sans Frontiéres MSF-Spain, on Nurse Scheduling, through the most less cost effective and workload sharing techniques, in former Boko Haram stronghold that was formally declared as the insurgents headquaters referred as the Caliphate on the 7th August, 2014 by their Leadership. This hospital is located in central area of the local government called Gwoza General Hospital. The most difficult and highly volatile, risk area in Borno State Northeast-Nigeria, that was classified as a red zone by the security intelligence reports. The task of Nurse Scheduling to meet up with the community counseling, traumatized patients by the armed gunmen, hetherto the hectic and herculean task patients needs when considered the services rendered during the crisis period at the peak of the insurgency, Military hostility and subsequent Government declaration and pronouncement of curfew on all sorts of movements sometimes between the 1600hours to 0700hours without any provision for alternative arrangement for the special health-care workers. We proposed a model to improve both the process and the quality of scheduling techniques. The objective is to maximize the fairness of the schedule among personnel. A numerical illustration and example of workload scheduling for a maximum of 8 hours is obtained and solved by correct simplex method, through Gauss-Jodan elementary row operation, the hospital needs a minimum of professional nurses to meet up with the patients needs to be more effective and efficient.

Statistical distributions are very crucial in describing and predicting real world phenomena. Although many distributions have been developed, there are always rooms for developing distributions which are either more flexible or for fitting specific real world scenarios. In this study we transform the Exponential-Gamma distribution using the technique that generates T-X family of distributions and we hope that this new T-X family of distributions will provide more channels for generalizing more flexible family of probability distributions.

A large proportion of online comments present on public domains are usually constructive, however a significant proportion are toxic in nature. Dataset is obtained online which are processed to remove noise from the dataset. The comments contain lot of errors which increases the number of features manifold, making the machine learning model to train the dataset by processing the dataset, in the form of transformation of raw comments before feeding it to the Classification models using a machine learning technique known as the term frequency-inverse document frequency (TF-IDF) technique. The logistic regression technique is used to train the processed dataset, which will differentiate toxic comments from non-toxic comments. The multi-headed model comprises toxicity (severe-toxic, obscene, threat, insult, and identity-hate) or Non-Toxicity Evaluation, using confusion metrics for their prediction.
