Authors: Bedada Alemayehu Ginbo , Riddle Elijah Wade , Eshetu Alemayehu Bekele , Azzie Georges
Published: September 2020

Cecal perforation following blunt abdominal trauma is an uncommon and challenging injury. We report a 19-year-old HIV-positive woman who presented with abdominal pain after a high-speed motor vehicle crash. Abdominal exam revealed a seatbelt sign with evidence of peritonitis; Focused Assessment with Sonography for Trauma showed free intraperitoneal fluid. After fluid resuscitation and antibiotics, the patient was taken for urgent laparotomy. Intraoperatively, we discovered hemoperitoneum and an isolated rupture of the cecum. A right hemicolectomy with end-to-end ileo-transverse colon anastomosis was performed. Her only significant postoperative complication was a superficial wound infection. We review the epidemiology of hollow viscus injury in blunt trauma and discuss important considerations in diagnosis and treatment.

Published: September 2020

Burn injuries come with enormous challenges and devastation to the victims. The consequences get worse when multiple members of a family are involved. Social supports are necessary, especially where health financing is mainly through out-of-pocket expenditure. The use of Medical Social Workers (MSW) in burn care in our region is limited, and their roles are poorly or inadequately reported. This study appraises the role of MSW in the multidisciplinary management of burn patients. We report the management of an impoverished family of five who sustained varying degrees of burn injuries, and the role MSW played in their care. Beyond being a routine discharge planner, the MSW provided social support, psychotherapy and rallied community support, which translated to an improved outcome for the patients. Involving MSW in burn care provides great benefit to patients. Burn surgeons are therefore encouraged to use the added value of MSW on their teams.

Numerical solution of singularly perturbed self-adjoint boundary value problem using Galerkin method
Authors: Salih Murad Hussein , Duressa Gemechis File , Debela Habtamu Garoma
Published: September 2020

This paper presents numerical solution of second order singularly perturbed self-adjoint boundary value problems using weighted residual method of Galerkin type. First, for the given problem, the residue was computed using appropriate approximated basis function which satisfies all the boundary conditions. Then, using the chosen weighting function, integrating the weighted residue over the domain and the given differential equation is transformed to linear systems of algebraic equations. Further, these algebraic equations were solved using Galerkin method. To validate the applicability of the proposed method, two model examples have been considered and solved for different values of perturbation parameter and with different order of basis function. Additionally, convergence of error bounds has been established for the method. As it can be observed from the numerical results, the present method approximates the exact solution very well. Moreover, the present method gives better accuracy when the order of basis function is increased and it also improves the result of the methods existing in the literature.

Keywords: Singularly perturbed problems, Self-adjoint problem, Galerkin method, Boundary value problems.
Pectoral muscle deletion on a mammogram to aid in the early diagnosis of breast cancer
Authors: Vagssa Pascal , Doudou Nafissatou Mallam , Jolivo Tchoning , Videme Olivier , Kolyang Dina Taïwé
Published: September 2020

Mammograms are the images used by radiologists to diagnose breast cancer. In this diagnosis, the pectoral muscle appears in mammograms in  oblique mediolateral views (MLO) of the right breast and another in the left breast appears in cranio-caudal views which are marked with (CC). Considering that the pectoral muscle has the same density as the small, suspicious masses in the image, its presence in the image being processed could also require detection procedures. In this paper, we present a new general framework for pectoral muscle suppression which is the first work in the analysis of a mammography image. As a result, we proceed to four stages of image processing. The first step is to orient the image if necessary, then use a pre-processing which is to enhance the contrast of the image, and remove the digital lines of the image by morphological filters, apply a filter median. The third step involves segmenting all of the pectoral muscles, which involves threshold the entire image. The final step is to perform a pectoral muscle removal according to the orientation of the muscle in the image, which will be based on the development of the Hough transform for the recognition of borderline detections of the pectoral muscle. Some results obtained on the different images are discussed and compared with other methods (risk assessments). Evaluation of our method shows a significant improvement in performance in removing the pectoral muscle.

Cascaded single-phase, PWM multilevel inverter with boosted output voltage
Authors: Nnadi D.B.N. , Oti S.E. , Odeh C.I.
Published: September 2020

Splitting of a dc voltage source with two capacitors has been the approach in generating 5-level output voltage with single- and three-phase full-bridge circuits and added bidirectional switch. Associated with this configuration is the problem of voltage imbalance between the splitting capacitors. In addition, the inverter output voltage magnitude is obviously limited to the value of the split input voltage source. Presented in this paper is a unit topology for single-phase 5-level multilevel inverter, MLI. It simply consists of a full-bridge circuit, a capacitor, charge-discharge unit and a dc source. The charge-discharge unit with the capacitor is the interface between the full-bridge and the dc source. The proposed unit cell can generate a 5-level output voltage waveform whose peak value is twice the input voltage value. For higher output voltage level, a cascaded structure of the developed unit cell is presented. Comparing the proposed inverter with CHB inverter and some recent developed MLI topologies, it is found that the proposed inverter configuration generates higher output voltage value, at reduced component-count, than other topologies, for a specified number of dc input voltages. For two cascaded modules, simulation and experimental verifications are carried out on the proposed inverter topology for an R-L load.

Groundwater depletion in the upper aquifer of the chad formation, Chad basin, North-Eastern Nigeria
Authors: Adamu S. , Sadiq H. M. , Kodomi M.G. , Wulo I.B.
Published: September 2020

This paper examines the present groundwater level changes in the Upper aquifer of Chad Formation in Borno basin measured in the year 2007, 2008, 2009, 2011 and 2012. The study involved collection of topographic maps of scale 1:500,000 on Nigerian sheet 4 covering the study area. Previous published literatures on the basin were also collected. Hand dug wells and their elevation were located and measured with satellite navigator. Findings from the results shows that, the Upper aquifer is a phreatic aquifer separated by thin clay layer into “A” sub-zone with depth ranging from 1 to 10 m, “B” sub-zone with depth ranging from 10 to 60 m and “C” sub-zone with depth ranging from 60 to 100 m. From the study, it can be deduced that, the C sub-zone is not recharging from seasonal infiltration of meteoric water or from the horizontal stream flow, it rather shows a depleting groundwater level. It was proved that rain of wet seasons do not recharge Upper C sub-zone to the previous wet season level, and thus the water table in the Upper C zones will be exhausted if the aquifer is not recharged at the present level of abstraction.

Keywords: Groundwater, Chad Basin, Phreatic aquifer, Depletion level and Upper aquifer.
Phytochemical screening and antibacterial activity of Garcinia kola (hackel) and Cola nitida (vent) extracts
Authors: Afolabi B.T. , Agu G.C. , Onajobi I.B.
Published: September 2020

This study was designed to evaluate the phytochemical and antibacterial properties of Garcina kola (Orogbo) and Cola nitida (Obi) extracts. Fresh seeds of Cola nitida and Garcinia kola were collected from Ago-Iwoye market, Ogun State. The ethanolic and aqueous extracts of the test plants were used against selected test organisms, Streptococcus pneumonia, Staphylococcus aureus, Salmonella typhi, Pseudomonas euriginosa and Escherichia coli. Disc diffusion method was adopted to test for susceptibility of the selected test bacteria to the extracts. Minimum inhibition concentration (MIC) and Minimum bactericidal concentration (MBC) were determined. Bioassay data were statistically analyzed using two-way ANOVA. The result of the phytochemical screening confirmed the presence of flavonoid, phenol, alkaloid, saponins, tannins and phlobatanins. The result of the antibacterial activity showed that the ethanolic extract of the test plants recorded highest antimicrobial activity against test isolates compared to aqueous extracts. The tested plant seeds of both plants posses reasonable antibacterial activity but to varied zones of inhibition, with Staphylococcus aureus isolate having the highest inhibitory zones (21.33) mm while Pseudomonas aeuruginosa had the least inhibitory zone (6.00) mm. The antibacterial activity were however found to be concentration dependent (Fvalue= 3.996, Pvalue= < 0.05). All tested organisms were found to have definite MIC and MBC activities which ranges between 125 and 1000μg/ml for MIC except for Kola nitida that has no definite MBC below 1000μg/ml. The result confirms the potential of antibacterial activity of Garcinia kola and Cola nitida extracts.

Power energy distribution and consumption in Nigeria: The way forward for sustainable industrial and commercial development
Authors: Okpare A.O. , Okreghe C. O.
Published: September 2020

The wasteful, non-efficient way and manner in which the small, available power energy in Nigeria is distributed and consumed especially by residential consumers, is such that it cannot grow the country sustainably. The result is that Nigeria will continue to remain a developing economy with the associated features. This paper examines the current electricity distribution and consumption scenario in Nigeria and also discusses the myriads of problems associated with the distribution and consumption of power energy in the country. Available data and findings presented in this paper show that distribution of electricity is bedeviled with high losses and is corruption ridden while consumption is wasteful and non-efficient. The paper makes some suggestions on the way forward for Nigeria to grow sustainably. The paper concludes that unless the current electricity distribution and consumption patterns are reversed and re-patterned, industrial and commercial advancement will continue to elude the nation. The paper recommends the way forward on how to re-position the power energy sub sector of the economy so as to achieve sustainable national development.

Water infrastructure maintainability – issues and challenges in the coastal regions of Akwa Ibom State
Authors: Okon B.B. , Okon V.E. , Udom E. J.
Published: September 2020

In this study, incessant collapse of water infrastructure along with shortage of water supply from public mains due to poor maintenance culture within the coastal areas of Akwa Ibom State are the key issues and challenges associated with the performance of water infrastructure in the area under consideration. These indices have been of great concern to building services engineers, estate managers and other stakeholders within the built environment. With the option of continuous (periodic) and practical maintenance culture as a panacea, effective water supply is guaranteed. This study has established better ways of tackling these problems (indicative risks) concerning maintainability of water infrastructure for optimum service delivery. Qualitative analyses were performed on air and water samples collected within the affected water infrastructure environment. In this case, concrete water stanchions (CWS) and steel water stanchions (SWS) along with the mechanical systems: submersible pumps, control valves performance were also evaluated to ascertain the level of environmental damages meted on the water works over a period of time upon  commissioning and use. From the achievable tests, it is evident that the pH (-) results are higher in the investigated CWS than SWS except the turbidity results which are at par. These results have demonstrated that CWS is preferable to SWS for ease of periodic maintenance.

Authors: Zhang Lei , Li Zhicheng , Yang Tianliang , Yang Ping
Published: September 2020

Large-scale constructions of urbanization increase the impervious areas of city, leading to the urban hydrological effects such as urban waterlogging and rainwater runoff pollution. To this end, China proposed to adopt the measure to build sponge cities. However, the existing green soil cannot meet the comprehensive needs of sponge city. In order to quickly evaluate the comprehensive performance of the soil in sponge city, a comprehensive evaluation criterion was designed, which is related to the characteristics of greening soil permeability, porosity, pH, salinity and fertility. Based on the criterion, a new type of composite green soil was obtained with the silt soil: medium sand: sawdust ratio of 72.5%: 20%: 7.5%. Finally, compared with the existing soil, the new green soil not only meets the comprehensive performance requirements of the green soil's fertility, pH, permeability and other factors, but also has higher permeability and water retention. It was proved that the new green soil has apparent advantages in the control of rainwater.

Las organizaciones tienen características muy diferentes de cómo operar dentro del ámbito laboral, cómo seguir creciendo día con día y uno de los principales pilares es el factor humano en el que tienen una fortaleza muy importante para el éxito. La competencia entre lasorganizaciones y particularmente los avances tecnológicos han provocado cambios muy importantes, que se ven incluso en la forma de administrar las empresas, lo que ha empujado a estas últimas a tener asesores en su plantilla laboral que les ayuden en el área del comportamiento humano de su personal. La cultura de una organización incorpora sus valores, creencias y actitudes, y es la fuerza impulsora de esta conducta.

Este artículo expone aquellas posturas teóricas que permitan comprender el quehacer de la administración de los recursos humanos y su relación coyuntural con el clima organizacional para el buen manejo. Ofrece al administrador y al directivo organizacional una comprensión de la dinámica humana del trabajo y de la productividad de las personas, distinta de la visión que ofrecen los modelos prescriptivos gerencial eso las tradiciones empresariales y, por tanto, más ajustada al saber científico desarrollado en el contexto cultural del propio país y región.

Published: September 2020

El programa de Licenciado en Derecho, se rediseñó, desde su última reforma, bajo un modelo por competencias, diferenciadas en aquellas competencias genéricas o transversales y específicas para la abogacía; así, el programa educativo comprende a la flexibilidad con las competencias del saber, hacer, ser, adaptable a las condiciones de empleabilidad, de la formación integral para el manejo de los conocimientos, de su adaptabilidad, de la toma de decisiones a partir de los contextos, y de su permeabilidad en los escenarios que ofrece la sociedad del conocimiento. Estructuralmente, en la malla curricular del programa de derecho se aplicó esta flexibilidad, en la eliminación en lo más posible de los aparentes “candados” de seriación de materias, suprimiendo los requisitosprevios y dejando a la capacidad electiva del alumno la construcción de su carga curricular, inclusive para la prestación de las prácticas profesionales. Esta construcción que prioriza la flexibilidad, ha provocado condiciones de inconsistencia en la trayectoria académica, una situación primaria de cimentar áreas cognitivas y disciplinares básicas se deja a la disposición del alumno generando así problemas de debilidades formativas, se elevan los grados de complejidad temática y competencial, incluso de la secuencia de contenidos del derecho sustantivo y adjetivo; además de la ampliación de la flexibilidad a la supresión de requisitos en prácticas profesionales y la diversificación de opciones de titulación. En la presente aportación se plantea como hipótesis que:el concepto de flexibilidad de la propuesta del modelo educativo institucional para la licenciatura en derecho se ha aplicado en forma excesiva, provocando complicaciones a los actores del proceso enseñanza aprendizaje, debilitando el andamiaje cognitivo y formativo.

Published: September 2020

Introduction: Obesity is a global public health problem with negative impact on health. Therefore, effective treatments options are needed. Objective: to evaluate the responses of a supervised functional training program on physical fitness and functional capacity of women with obesity. Methods: a prospective and controlled study was conducted with twenty-four women, BMI >30 and <55 kg/m² and age between 20 and 59 years. The evaluation consisted of anthropometric measurements and physical fitness tests that assessed the cardiorespiratory fitness and functional capacity [6-minute step test (ST6min)], the indirect strength of the lower limbs [sit-to-stand test (STS)] and the flexibility [sit and reach test (SR)]. After the baseline evaluations, the volunteers were allocated in two groups: individualized training group (ITG) (n=13), which consisted of aerobic and strength training, for three months, three times a week, 60 minutes per session; and the control group (CG) (n=11) which did not participate in any regular physical exercise program during the same period. At the third month the two groups were reassessed. Results: it was observed significative reductions in waist circumference, hip and neck measurements; all with p<0.01; and increase in VO2max, in the number of movements of STS and in distance reached in the SR test, all with p<0.01 for the ITG. The ITG showed superiority over CG for all exercise test variables studied. Conclusion: The training program improved the distribution of body fat, cardiorespiratory fitness, muscular strength, flexibility and functional capacity. These are indicatives that the strategy is feasible for women with obesity.

An Empirical Study of Some Driving Factors of CO2 Emissions: Evidence from Quantile Regression
Authors: KEHO Yaya
Published: September 2020

A growing body of research has examined the determinants of CO2 emissions. This literature has used mean-based regression methods in which only the mean effects of covariates are estimated. In this paper, we use the quantile regression methodology for a panel of 45 countries to investigate whether or not the factors that drive pollution do so in the same way for high and low pollution countries. The Environmental Kuznets Curve is confirmed and the positive effect of economic development is larger in low pollution countries. Energy consumption and financial development increase CO2 emissions and their effects are larger in countries with lower levels of pollution. Industrialization increases pollution especially in countries with higher level of pollution. Openness to trade and urbanization are negatively related to emissions in low pollution countries. All these findings suggest that pollution control policies should be tailored differently across low and high pollution countries.
Some reflections on the importance of ‘how to rule”
Authors: Lagi Sara
Published: September 2020

The present article proposes some reflections on the issue of “how to rule” as crucial to think about politics in terms of limits on government and thus in terms of preservation of fundamental freedoms. By referring to some of the most prominent thinkers of European Liberalism, the article examines the principle of “how to rule” in relation to that of “who rules” in order to stress how just the latter can imply – if isolated from the former – potentially dangerous elements for the guarantee of a free and civic coexistence. In the last part, the article recognizes the relevance of Liberal-democratic tradition of thought as a compromise between the two principles.

Totalitarismo em The Handmaid’s Tale: entre manipulação e programação
Authors: Resende Natália Silva Giarola de , Mendes Conrado Moreira
Published: September 2020

Neste trabalho, com base nos regimes de interação e sentido da teoria sociossemiótica (LANDOWSKI, 2014), temos como objetivo compreender como se constitui o regime totalitário de Gilead, nação fictícia da série distópica The Handmaid’s Tale, com base na análise do primeiro episódio, intitulado Offred. A partir da articulação entre os fundamentos teóricos – totalitarismo (ARENDT, 2012; NEUMANN, 1969; TURPIN, 2012) e sociossemiótica – e das reflexões resultadas da análise, verificamos que tanto o regime da manipulação quanto o da programação legitimam a conservação do Estado totalitário.
An analysis on paradoxical gender equality+ policies and the violence in Brazil
Authors: de Souza Renan
Published: September 2020

Brazil records alarming rates of epidemic violence against women and LGBTQ+. According to statistics, the country ranks as the fifth most violent for women and the deadliest in the world for homosexuals. On the other hand, progressive policies to support both groups have been implemented by different public administrations in the last decades generating remarkable milestones. Despite being considered as cutting-edge, those actions have not necessarily translated into a reduction of violence. One explanation for these paradoxes between progressive policies to protect women, LGBTQ+ and the frequent violence against these groups, might be found in historical, cultural, and religious roots. This article highlights that, notwithstanding that some progress was made in Brazil, the rise of conservative and far-right groups may undermine all the advancement reached in the last decades, which could lead to the aggravation of the gender-based violence in the country
