Authors: Li Wei-Qin , Quan Mei-Ping , Li Qin
Published: December 2019

Chemical composition of the essential oil from Qiancao roots was analyzed by gas chromatography-mass spectrometry (GC-MS), and 43 components were identified in the paper. Mollugin (30.58%) was found to be the major component, followed by 3-methyl-2-cyclopenten-1-one (10.55%), 4-tert-butyl-2-phenyl-phenol (8.64%) and eugenol (6.30%). The antibacterial activity of essential oil against selected food-borne pathogens was evaluated. The results showed that the sensitivity to essential oil were different for different tested bacteria and the essential oil had a strong antibacterial activity against B. cereus with the lowest minimum inhibitory concentration (MIC) and minimum bactericide concentration (MBC) values of 0.0625 and 0.125 mg/mL, respectively. In addition, microbial growth curve assay also showed that the essential oil had a significant effect on the growth rate of surviving B. cereus. The data of this study suggests that the essential oil from Qiancao roots has great potential for application as a natural antimicrobial agent to preserve food.

Authors: Talabi Abel O.
Published: December 2019

Background Objective: River Ose has flowing water throughout the year that can serve for irrigation and domestic purposes. This study examined the hydrochemistry, water quality indices and coliform counts of River Ose Water, Nigeria with a view to ascertain its suitability for drinking and irrigation.Materials and Method: For this purpose, 15 water samples were collected along the flowing river channel and subjected to physico-chemical and e-coli determination using standard methods. Water quality index (WQI) and Irrigation parameters (Sodium adsorption ratio (SAR), Percentage sodium (%Na), Residual sodium bicarbonate (RSBC), Kellyâ€™s ratio (KR), Permeability index (PI) and Magnesium absorption ratio (MAR)) were calculated from the chemical data obtained from the analyses.Results: Results of the analyses revealed that pH (9.7 pHÂ of the water samples were of alkaline nature with all the water samples exceeding approved standard for drinking water. Drinking alkaline water may deactivate pepsin but it could lead to gastrointestinal problems and metabolic alkalosis. Electrical conductivity (ÂµS/cm), Total dissolved solids (mg/L) as well as Total hardness of all analyzed water samples fell in the category of fresh water. HCO3- and Cl- were the dominant anions while Na+ and K+ constitute the dominant cations in the water chemistry. The abundance of major ions revealed Na+> K+ >Mg2+>Ca2+ and HCO3->Cl->SO42->NO3- trend. The dominant hydrogeochemical facies was mixed Ca2+-Na+-HCO3- (93%) with few mixed Ca2+-Mg2+-Cl- (7%) while calculated WQI was 89.44. All samples tested positive to e-coli count ranging from 1.71*101 â€“ 8.100*103.Conclusion: The analyzed physico-chemical parameters in all River Ose water samples were well within approved desirable limits except for the pH. However, the water was not potable as all samples tested positive to e-coli counts. In addition, WQI calculation revealed that the water has very poor drinking quality. Sources of ions in the River were predominantly from rainfall and minor weathering from the bedrocks. Irrigation quality parameters (SAR, %Na, RSBC and KR) indicated that River Ose water was good for irrigation. However, applying the water on salt sensitive plants is not advisable as irrigation evaluation employing PI and MAR showed that the water was not suitable for irrigation.

Published: December 2019

The flow behavior of liquid-solid particles in mixing tanks using a modified Rushton impeller, called a Rushton V-cut impeller, was studied. Both the Rushton and Rushton V-cut impellers were compared at a 300 rpm stirring speed and a 10 % wt solid concentration. Hydrodynamic behaviors, such as solid volume fraction, velocity, pressure, and shear stress, in both the Rushton and Rushton V-cut impellers were investigated. Computational fluid dynamics (CFD) software able to understanding of hydrodynamics of stirring liquids which contain solid particles. CFD programme was to predict the mixing flow of the highly viscous system. Therefore, the present work was carried out using CFD software with the Eulerian-Eulerian approach with a turbulent k-Îµ model. The simulation of mixing tanks was consisted of moving and stationary zones by using moving references frame method or MFR. The results were observed that Rushton V-cut can dramatically reduce pressure up to 20% and the shear stress up to 64.38% while keeping the liquid-solid mixing at a considerable degree. Therefore, this design can reduce the power consumption.
Degradation of GNSS Accuracy by Multipath and Tree Canopy Distortions in a School Environment
Authors: Uzodinma Victus N. , Nwafor Uchechukwu
Published: December 2019

Accurate position determination with GNSS technology requires unimpeded view of the sky. It has however been noticed that control stations established with GNSS technique for surveying/research projects no longer yield the desired accuracy after some years. This could be as a result of environmental features (buildings, fences, trees, etc) sprouting around them due to infrastructural development and urbanization. This paper investigates the extent of degradation of accuracy at fifteen such stations located within a school environment. The study was done by comparing GNSS fixes of those stations with their corresponding positions determined in a total station (electronic tacheometer) survey. The latter was used as study control because it is not affected by the environmental features and factors monitored. The study showed that some of the stations are no longer suitable for the GNSS technique (GDOP is too high (171.6)); while for others, their GNSS-derived positions differed from those of total station by as much as 5.7m. All the controls were therefore reclassified in accordance with national and international accuracy standards. We also recommend that once in a while such checks and reclassification should be done for existing controls.

Published: December 2019

Fractional Polynomial regression is a form of regression analysis in which the relationship between the independent variable and the dependent variable is modelled as a 1/nth degree polynomial. Thus, this work is used to propose an extension of Fractional Polynomial Regression (FPR) term Lagged Fractional Polynomial Regression (LFPR) which is an alternative method to traditional techniques of analysing the pattern and degree of relationship between two or more continuous non-linear data. The coefficients of the proposed method were estimate using Maximum Likelihood Estimation method. From the results, the LFPR model indicated that for a unit increase in Evaporation, Humidity and Temperature there will be an increase in the millimeter of rainfall series on yearly basis. The value of coefficient of variation (R2) for the LFPR and FPR were 99% and 77%. While the value of adjusted Coefficient of Variation (R2) for LFPR and FPR were 96% and 75% respectively. Hence, the proposed method outperformed and adequately explained the variation in the dependent variable better than Fractional Polynomial Regression based on the values (R2) and adjusted (R2).
Human Resources Development and Sustainable African Development: A Reconsideration of Some Fundamental Issues
Authors: Nwakpa Paul
Published: December 2019

The ambition of this paper was to examine the role of human resources in sustainable African development. It argued that the nexus between human resources development and sustainable development cannot be over-emphasized. It observed that during colonial rule, the policy on human resources development was discriminatory to the disadvantage of Africans. It further argued that the place of intellectuals in the development of human resources could not be ignored as their role is a sacred one and blamed poor human resources development record in Africa on bad leadership. It lamented the inability of government to make good use of recommendations of intellectuals during seminars, workshops and conferences. The paper concluded that a holistic approach should be adopted which would place human beings at the centre of development and recommended among others that poverty should be reduced while people should be made to have access to education and health.

Published: December 2019

The objective of this study was to analyze the teachers' view on the importance and the use of a medicinal garden in a public school in a city in northeastern Brazil. It was analyzed how this resource can contribute as a didactic material for the interdisciplinary practice in basic education. The school garden was planted in the second half of 2014, through an intervention project promoted by the University of Pernambuco's Program of Initiation to Teaching (PIBID) Program, linked to the Coordination of Improvement of Higher Education Personnel of the Government of Brazil (CAPES). A semi structured questionnaire was applied to thirteen teachers at the school. The results obtained in the interviews showed the teachers' lack of interest regarding the use of the school garden. Even so, most teachers recognize the importance of the school garden as a didactic resource. With this study it was possible to observe that any project of intervention in the schools requires that the teachers are ready to use it. It is necessary to create a teacher training plan. Alternative teaching tools show themselves as stimulating actions in learning and as an efficient didactic resource in modern school.

Published: December 2019

The direct measurement of body composition using innovative non-or minimally-invasive technologies such as stable isotope technique, despite its reliability and precision remains a significant challenge. Â This study was designed to develop predictive equations for estimating the percentage body fat of Nigerian women using isotope dilution (ISD) or gold standard technique (as in IAEA procedure) as reference and validated by bioelectrical impedance technique.The percentage body fats (% BF) of 173 Nigerian women (aged 18-55 yrs) were estimated using isotope dilution (ISD) or gold standard technique (as in IAEA procedure) as reference and validated by bioelectrical impedance technique. The skinfold thicknesses (mm) such as biceps, triceps, subscapular, suprailiac and abdominal were measured using skinfold langre callipers while body circumferences such as forearm, wrist, waist, abdominal and hip were measured using standard tape rule and in accordance with WHO guidelines.Â  The subjectsâ€™ percentage body fat (%BF) ranged from 8.0 to 48.5. Generally, at 0.01 level of significance (Using Statistical Package for Social Scientists (SPSS), higher positive significant correlations were obtained between % BF by ISD and body circumferences (r=0.503-0.874) than skinfold thicknesses (r=0.503-0.739). Using forward selection regression procedure, three sex-specific based predictive equations for estimating %BF (incorporating subjectsâ€™ weight and body circumferences such as hip, abdominal and waist) were developed based on the subjectsâ€™ ethnic groups (Yoruba, Hausa and Ibos) with high R2 (0.853, 0.953 & 0.867) and low Pure errors (3.316, 2.791 & 2.324) respect. These equations provide easy way of measuring percentage body fat and are recommended for use in clinical or epidemiological settings in populations with similar ethnic background and in lieu of isotope dilution method.

Evaluation of the Efficacy of a Field Isolate of Eimeria Oocysts Immunization in Two Breeds of Chickens - Demystifying use of Coccidiosis Vaccines
Authors: Ngongeh Lucas Atehmengo , Nwaiwu Felix Ezuchukwu , Fakae Barineme Beke
Published: December 2019

Immunization efficacy of a field isolate of unattenuated sporulated Eimeria oocysts in broiler and Nigerian indigenous chickens (NIC) was investigated. Both breeds of birds were grouped and inoculated with varying dose levels (750, 1500 and 3000) of the oocysts per bird. Â The immunizing infections were truncated with an anticoccidial drug following detection of patency evident by presence of Eimeria oocysts in the faeces of inoculated birds on day 4 of inoculation. Â Immunized birds were then given challenged infections of 10,000 oocysts of the same Eimeria isolate per bird and an additional group that did not receive the immunizing infections was also challenged with 10,000 oocysts to serve as the unimmunized-challenged control while another group remained as uninfected-unchallenged control. Â Immunized birds were found to be protected against the challenge infections evident by having significantly less severe gross lesion scores (0 to 1) in contrast to the unimmunized-challenged control birds (which had lesion scores of 2 to 4 and 1 to 2 in broiler and indigenous chickens respectively). Â The infection was more severe in broiler chickens in contrast to the indigenous chickens judged by more severe lesion scores and significantly higher oocysts counts in the broilers. Â Broilers also had significantly lower PCV (P < 0.05) in comparison to their indigenous counterparts. Â Infected birds generally suffered infections more in contrast to the uninfected control birds judged by the significantly higher body weights and PCV of the uninfected birds (P < 0.05). Â The results showed that the protection of birds against coccidiosis by immunization with the Eimeria isolate is feasible and this can therefore serve as a premise for the recommendation of immunization against coccidioisis in eastern Nigeria where the practice is extremely low or unknown by poultry farmers and hardly recommended to poultry producers by veterinarians and their allies in spite of the endemicty and severity of the disease in the area. Â All the dose levels tried in this study were protective with no obvious differences between the dose levels and we recommended the use of 750 oocysts of such isolates to minimize the risk clinical coccidiosis. Local isolates of Eimeria would also have the added advantage in that they are likely to contain multiple Eimeria species that could provide full protection against the entire spectrum of Eimeria that occur in the area.Â Â

Published: December 2019

Acute Myocardial Infarction (AMI) is a manifestation of acute myocardial ischemia and is generally caused by the rupture of atherosclerosis and thrombus in the coronary blood vessels. Rupture causes an inflammatory process that leukocytes which acts as a marker of inflammation increases. Heart muscle damage that occurs also resulted in levels of troponin I as one of the markers of increased cardiac examination. Based on that research aims to determine the correlation between the levels of troponin I and the number of leukocytes in patients with suspected AMI.This research method is analytical observation with a data sample of 100 patients with suspected AMI diagnosis by doctors as well as examine the levels of troponin I and the number of leukocytes in dr. Abdulmadjid Chasbullah Bekasi. The correlation between the levels of troponin I and leukocyte counts were analyzed using Spearman's test. Data studied consisted of 52 people (52%) men and 48 (48%) of women. By age group, age range 46-65 years become the largest age group into patients with suspected AMI is 55 people (55%). Obtained 34 (34%) of patients with suspected AMI who had higher levels of troponin I and normal leukocyte count, and 39 (39%) of patients with suspected AMI who had troponin I levels and elevated leukocyte count. On Spearmanâ€™s test seen the correlation between levels of troponin I with the total of leukocytes in patients with suspected AMI (p = 0.000 and r = 0.50). This shows an increase in troponin I, which runs parallel with the increase in the total of leukocytes. Suggested for further research to see the difference increased levels of troponin I and the total of leukocytes between 3-5 hours and 14-18 hours after myocardial injury

Published: December 2019

The study examined the interrelationship among economic growth, environmental pollution and human health for Sustainable Development (SD) in Nigeria. This was to contribute to the dynamic debate of how human and economic activities relate and interrelate with environmental pollution in measuring sustainable development in Nigeria. This study further sought to verify the Environmental Kuznet Curve Hypothesis in Nigeria.The study employed the Vector Error Correction Model (VECM) to investigate linear and interrelationship mainly among life expectancy at birth, economic growth and environmental pollution in Nigeria from 1970-2015. Since the variables have unit root and revealed that there is at least a cointegrating equation in the model, the VECM become a more appropriate model for the study.The VECM Impulse Response Function (IRF) result indicated that economic growth increased environmental degradation in the long run and environmental degradation on the other way round reduced economic growth in most of the period of the study. The VECM system conditional forecast of 10%, 20% and 26% from 2000 to 2015 periods showed that a 10%, 20%, and 26% reduction forecasts of environmental pollution led to a consistent increased economic growth and life expectancy at birth of the country in the study. This indicated that a reduction in environmental pollution will improve the health of Nigerians and also enhance a sustainable development in the country.The study concluded that environmental degradation reduces economic growth while economic activities in the country increases environmental degradation in the country. From the conditional forecast, the study further concluded that efforts in reducing environmental pollution through policies and better environmental friendly economic activities will improves economic growth for sustainable development in the country.

Published: December 2019

SrTiO3 is a dielectric material of considerable interest. However, the relationships between microstructure and dielectric properties have not been studied in detail. Hence, we have undertaken an extensive experimental work to study the evolution of the dielectric properties against morphological changes of SrTiO3. SrTiO3 was prepared using the mechanical alloying method and samples with nano-sized starting powder were obtained. The milled powder was pressed into pellets and sintered at various temperatures ranging from 500 Â°C to 1400 Â°C. XRD studies showed that these ceramics completely formed a perovskite phase at 900 Â°C. FeSEM studies show the presence of small grain sizes ranging from 120 to 600 nm. Dielectric constant (Îµrâ€™) and dielectric loss tangent (tan Î´) were measured as a function of frequency and correlated with the microstructure. Îµrâ€™ and tan Î´ against frequency show a falling trend at the lower frequency region due to the changing interfacial effect. For sintering temperatures 1000 Â°C to 1100 Â°C, grain size and XRD peak data show a significant increase with the corresponding increase in Îµrâ€™, suggesting a sudden increase in the polarizability due to significant increase in crystallinity. With increasing sintering temperature, Îµrâ€™ increased proportionally with XRD peak and grain size increases, further confirming polarizability and crystallinity relationship. tan Î´ correlation with microstructure does not have a common trend.

Published: December 2019

Because of the significant role of Cyber-Physical Systems (CPSs) in our lives, the security of these systems is of paramount importance. Due to the complexity of inside CPSs components, current methods need special skills to understand their workflow. The approach available in this regard, more than comfortability, have the ability to adapt to the network conditions. In this research, we present the secure routing problem of CPSs as a multi-objective optimization model and then solve it through three Evolutionary Algorithms (EAs). The main reason four using EA is that it allows satisfying the time constraints in the routing. Multi-objective optimization produces optimum values for objectives simultaneously.

Published: December 2019

Â Â Â Â  The effect of garlic supplementation on egg traits and productive performance of laying chickens have been widely studied but little information is available on the basis of strains while the issue of level of inclusion is an ongoing debate. This study investigated the effect of garlic supplementation on the productive performance and egg traits of Isa-brown, a specific strain of laying hen. Forty eight Isa Brown layers were randomly selected and allocated to four dietary treatments; each treatment had twelve layers consisting of three in a cage compartment and in four replicates. The treatments consisted a control, 0.5, 1 and 2 % garlic powder supplemented diets and fed to the layers for twelve weeks. Data were collected on growth parameters, egg traits and cholesterol contents. The dietary treatments significantly (p<0.05) reduced the body weight, feed intake, egg weight and hen-day egg production to the least values at the 2 % level of garlic powder inclusion but the feed efficiency was not affected. Garlic supplementation significantly (p<0.05) increased the albumen index, shell index, shell weight, Haugh unit and yolk cholesterol. The 1% garlic inclusion level gave the highest albumen index and Haugh unit while the highest shell index at 2 % garlic supplementation was due to significant (p<0.05) reduction in shell weight. Garlic significantly (p<0.05) decreased the egg yolk cholesterol but did not affect the yolk index and the yolk weight. Garlic supplementation in Isa Brown layersâ€™ diet should not exceed 1 % inclusion in order to avoid reduced productive performance and egg quality.

Soil-Transmitted Helminthiasis is caused by nematode worm infections, namely Ascaris lumbricoides (round worm), Trichuris trichiura (whipworm) and Necator americanus or Ancylostoma duodenale (hookworm). At present, the prevalence of Soil-Transmitted Helminthiasis in Indonesia is still high. To reduce the prevalence of Soil-Transmitted Helminthiasis in Indonesia, the Ministry of Health of the Republic of Indonesia holds a mass worm treatment program for pre-school age children and school-aged children. The drug given is albendazole 400 mg single dose. This study aimed to determine the effectiveness of a single dose of albendazole 400 mg against infections of Ascaris lumbricoides and Trichuris trichiura. This study used a Pre-Experiment research design (One Group Pretest-Posttest). The research subjects were 66 people. Subjects positive for Ascaris lumbricoides were 37 people (mild infection 67.57%, moderate infection 27.03% and severe infection 5.41%). After giving a single dose of albendazole 400 mg to 37 people who were positive for Ascaris lumbricoides, 37 people had not found eggs of Ascaris lumbricoides on faecal examination after treatment. Positive subjects Trichuris trichiura were 54 people (mild infections 51.85%, moderate infections 44.44% and severe infections 3.73%). After giving a single dose of albendazole 400 mg to 54 positive people Trichuris trichiura, in severe infections, the percentage of eggs dropped was 100%. In moderate infections, the percentage of the number of eggs dropped is 95.83%. In mild infections, the percentage of total recovery was 7.14%, and the percentage of eggs dropped was 39.29%. The results of the Wilcoxon test on Ascaris lumbricoides obtained a significance value of <0.05, which means that there are significant differences in the examination before treatment and after treatment. The results of the Wilcoxon test on Trichuris trichiura obtained a significance value of 0.05, which means there were no significant differences in the results of the examination before treatment and after treatment. Albendazole 400 mg single dose is effective against Ascaris lumbricoides infection and is not effective against Trichuris trichiura infection.

Published: December 2019

The purpose of this study is to find the characteristics that affect social entrepreneursâ€™ level of social contribution, and what should be done to empower social entrepreneurs with the observed characteristics to fulfill the needs of social welfare in Indonesia. In total, 106 valid units-of-research from a survey with a base response number of 5,620, provided by the GEM report of 2015, are analyzed, using a multiple linear regression method to find the characteristics of the social entrepreneurs. Previous literature is used to provide suggestions for practical implication. Based on the Five Social Entrepreneurial Characteristics, it is found that the only characteristic which significantly affects social entrepreneursâ€™ level of social contributions is perseverance. To nurture this attribute, social entrepreneurs could be driven to develop active partnerships with NGOs. Active partnerships would make social entrepreneurs develop not only perseverance, but also become more competent in contributing to social issues. This research is very specific for social entrepreneurs in Indonesia, and points to the possibilities of resorting to social entrepreneurs for fulfilling the demand of social welfare support rather than only depending on the government or NGOs. In addition, instead of encouraging the establishment of more social entrepreneurs, this research aims to foster their potential.
