Authors: Jimoh M.O. , Ogunmoyela O.A.B. , Ogabi O.N. 
Published: August 2020

The increasing demand for roasted plantain has brought about recent interest to upgrade the local method of roasting to be more user-friendly, hygienic and versatile. The objective of this work was to design, fabricate and evaluate the performance of a low cost and affordable multi-heat source plantain roaster and to determine the effects of different heat sources (charcoal, gas and electricity) on the proximate and micronutrients composition of the roasted plantain. Heat supplied to each compartment and medium of transfer was determined. The roasted products from different heat sources were evaluated for moisture, crude protein, ash, crude fat, crude fibre and total carbohydrate contents of the samples. Potassium, magnesium and vitamin B6 were also determined. The proximate and micronutrient composition analyses were carried out. The results show that the average capacity and efficiency of the machine is 3.74 kg/h and 96.32% respectively. Moisture content of the fresh plantain is 58.27% while that of roasted plantain using gas, electricity and charcoal are 46.26%, 45.94% and 39.59% respectively. Ash content of fresh plantain is 5.89% while that of roasted plantain using gas, electricity and charcoal are 7.45%, 8.30% and 7.00% respectively. Crude fibre content of fresh plantain is 2.83% while that of roasted plantain using gas, electricity and charcoal are 3.27%, 3.41% and 3.43% respectively. Carbohydrate content of fresh plantain is 23.80% while that of roasted plantain using gas, electricity and charcoal are 33.41%, 32.35% and 43.02% respectively.

Elucidation of Sodium Hydroxide Catalyst and Solids Loading for Thermochemical Liquefaction of <i>Tetraselmis sp</i>. Microalga
Authors: Eboibi B.E. 
Published: August 2020

The production of biocrude with and without sodium hydroxide catalyst (Na2CO3) through hydrothermal liquefaction of Tetraselmis sp. microalga at different organic solids loading was investigated. The HTL experimental study was conducted at reaction temperatures of 310oC, 330oC, 350oC and 370oC at 5 min fixed reaction time with organic solids loading of 10%w/w, 15%w/w, 20%w/w, 25%w/w, 30%w/w, and at 40%w/w. The results of the study showed that organic solids loading above 20%w/w had no substantial changes on biocrude yield. The catalyst had very little effect on the yield of biocrude but substantially enhanced its quality when compared with non-catalysed reactions. Although, Na2CO3 catalyst may be used for HTL of Tetraselmi sp. in laboratory-scale studies, it is highly unnecessary for commercial-scale. Thus potentially reducing the production cost in future commercialization of HTL-alga-biorefinery.

Investigating Cervical Lesion and Human Papillomavirus in Apparently Healthy Religious Women in Benin City, Nigeria
Authors: Odigie E.B. , Bolaji-Osagie S.O. 
Published: August 2020

Pathological abnormalities observed in cells or tissues obtained from the uterine cervix of women are collectively referred to as cervical lesions. The condition is gradually becoming a menace as it can affect different category of women. It is more worrisome as religious women particularly are not spared from the deadly scourge. This study was to investigate cervical lesion and human papillomavirus in relatively healthy religious women attending Pentecostal churches in Benin City, Nigeria. A cross-sectional investigation of the participants using structured questionnaire and the liquid-based cytology from January to July 2017 was used as the data and sample collecting tools. Majority of religious women that participated in the survey (n=429) cut across 47 Pentecostal churches. The mean age of the respondents was 48.46years (±2SD) with the highest number of participants being age group (36-45years) 131/429(31%), and ≥66years 13/429(3%). HPV infection was 9/429(2.1%), and the worst hit was among age group (26-35years) 5/429(1.2%) followed by 3/429(0.7%) amongst age group 36-45years, and 1/429 (0.2%) from age group 46-55years. 51/429(11.89%) was cervical lesion positive, while cytopathology revealed inflammatory smears (acute and chronic cervicitis), atypical glandular cells (AGC), low-grade squamous cell intraepithelial lesions (LSIL), and atypical squamous cells of undetermined significance (ASCUS). Cervical lesion and subsequent HPV infections are prevalent within the study population. However, to avert the impending dangers (cervical cancer) posed by cervical lesions in the society, modesty in sexual exploitation and decent lifestyles are highly imperative.

Deconstructing Denominationalism in Igboland: A Liturgy of Bitterness
Authors: Nmah Patrick Enoch 
Published: August 2020

This research work aimed at examining the effects of denominationalism in Igboland. The study revealed bitterness, antagonism, rivalry, moral barrenness, and spiritual bankruptcy that are dangers associated with denominationalism. Findings showed also the strengths and weaknesses of this narrow-minded party spirit in the area under review. The work recommended effective ecumenical-dialogue, exchange of programme, and inter-denominational communication as panacea to the challenges of party spirit. Methods of approach are historical and phenomenological methods coupled with the review of related extant materials. It concluded that shying away from engaging in inter-denominational relations through media for the purposes of Christian unity and evangelization amounts to playing the ostrich which has dire consequences. This paper assessed the challenges of worshipping God with bitterness among Igbo Christians. The problem is not planting Christianity in Igboland, but the method of evangelization which depends basically on denominationalism characterized by bitterness, envy, hatred, jealousy, wickedness and covetousness by which many Igbo Christians practice their faith. This in turn has adverse effect on the moral, social, intellectual and spiritual growth of the society. The bitterness is often within and without the denominations. The antagonistic attitude is seen among denominations such as Roman Catholic, Anglican, Methodist, Presbyterian, Seventh Day Adventist, Assemblies of God Church among others (Nmah, 2008).

Electoral Illiteracy and Democratic Citizenship in Zimbabwe
Authors: Zembere Monicah 
Published: August 2020

This paper argues that electoral processes in Africa with special focus on Zimbabwe are never fair due to rampant electoral illiteracy. In this paper, illiteracy is far beyond the inability to read and write but encompasses a high degree of ignorance from not reading. The theory informing arguments in the paper is democratic citizenship. This is a qualitative research where data has been gathered through interviews and observation. Zimbabwe’s election processes of 2008, 2013 and 2018 had been used as case studies to substantiate the findings of this study. The major findings are that besides electoral illiteracy, factors such as intimidation, fear, manipulation (vote buying), partisan and hero worshipping also compromise the credibility of elections in Zimbabwe. The other finding is that as long as citizens are not familiar with electoral process of their country, the levels of participation of such people will remain low. In the light of these findings, this research recommends effective active citizenship if electoral crisis in Zimbabwe is to be addressed.

Music as Art and Science: An Evaluation
Authors: Ibekwe Eunice. U. 
Published: August 2020

Music is presented in this discourse as a coin with two sides –thus as an Art also as a science. Looking at music as an Art draws one’s attention to the artistic features and characteristics of music such as styles and skills of performances as in dancing, singing, playing instrument and its position in other related areas with similar attributes. On the other hand, seeing music from the perspective of a science, the study of acoustics, sound productions, mathematical relationships and intervallic applications are evident. Art involves creative thinking and inspiration to achieve an expected goal or a set objective. Science on its own employs knowledge interaction and inquiries to produce new scientific discoveries. Music co-habits these two complex entities in a seemingly integrative association. This paper therefore is a critical examination and evaluation of musical potency that qualifies it as an art as well as science. The argument is anchored on qualitative evaluation of materials drawn from related literatures and sources. It finally draws the conclusion that since music fits in properly, and performs creditably as an art, as well as maintains great affinity with science, it should be treated as a bicameral discipline.

La pielonefritis aguda es una infección frecuente que puede progresar a absceso o pielonefritis enfisematosa (PE) la mayoría de los casos se produce por Escherichia coli. La presentación clínica puede oscilar desde síntomas leves hasta septicemia. La posibilidad de bacteremia depende de factores del huésped: pacientes que gravemente enfermos, inmunocomprometidos, con obstrucción del tracto urinario y mayores de 65 años. Más del 90% de PE se presenta en pacientes con diabetes. La nefritis intersticial afecta el intersticio renal, puede ser aguda o crónica, la mayoría de las veces debido a AINES o antibióticos. Ambas patologías son predominantes en mujeres.

Authors: Ribeiro de Souza Costa Cleonilde 
Published: August 2020

O presente estudo tem como corpus de pesquisa cinco poemas publicados na obra Cuia de Gedeão: poemas e autos sacramentais sertanejos (1982), de Pedro Casaldáliga. Constatou-se nessa seleção de textos uma estrutura imagética “Nós/Povo” estabelecida a partir da junção das vozes líricas obtidas no decorrer das análises dos poemas. O projeto imagético parte da ideia de “minoria”, canto solitário/solidário e se transforma no arquétipo maior, a “Grande minoria gedeônica”, o novo jeito de olhar as relações socioculturais de países imersos em lutas, em guerras em meados da década de 1970 e 80.

Migración intrapélvica (cut-in) en un clavo Gamma. Caso Clínico
Authors: Cañellas Trobat A. , Soucheiron Serra L. , Alcaide Matas F. , Cañellas Ruesga A. 
Published: August 2020

Una de las complicaciones de los clavos intramedulares es sin duda la implantación central del tornillo cérvico-cefálico. Aún así, la confluencia de diversos factores (osteoporosis, trazo de la fractura, reducción insuficiente del foco, motorización reiterada, etc.) pueden precipitar la salida de éste (cut-out) que viene a evidenciar una prevalencia del 2 al 4% de las diversas series y, ulterior aflojamiento del montaje. La presencia del cut-in, supone una eventualidad muy ocasional por debajo del 0,3% de la literatura. En este caso se ilustra una consolidación definitiva afortunada, tras un abanico de factores mecánicos y estructurales que encaminaron a una doble cirugía terapéutica. Se analizan los factores biomecánicos implicados en la génesis del cut-in.
One common complication of intramedullary nails is the central implantation of the cervico-cephalic screw. However, the confluence of some factors (osteoporosis, fracture line, inadequate focus reduction, repeated motorizing, etc.) can hasten a cut-out, showing a prevalence of 2 to 4% of the diverse series, and further assembly loosening. The presence of cut-in is an infrequent eventuality under the 0.3% of literature. The present case illustrates a fortunate definite consolidation, after a range of mechanical an structural factors leading to a double therapeutic surgery. The biomechanical factors affecting the cut-in origin are analysed.

Published: August 2020

La caracterización de biomateriales se sirve cada vez más técnicas no destructivas de obtención de imágenes. Estás técnicas pueden ser aplicadas tanto in vitro como in vivo con una resolución que depende del tamaño de la muestra y de la técnica utilizada. Una de las técnicas más utilizadas, por su alta resolución, es la micro tomografía axial computerizada (μ-TAC).
El objetivo de este estudio fue caracterizar andamios para ingeniería de tejidos óseos en términos de su arquitectura y porosidad usando reconstrucciones computacionales a partir de microtomografía y generar mallas tridimensionales para modelos de elementos finitos. Imágenes de dos materiales con morfología diferente fueron utilizadas. Un andamio de cemento de fosfato de calcio y un andamio de vidrio biodegradable poroso fueron escaneados con una resolución de 7,8 x 7,8 x 12,2 μm, para realizar posteriormente una recontrucción informática tridimensional y un mallado para análisis con el método de los elementos finitos. Se calculó la porosidad y se evaluó la interconectividad visualmente.
No se encontraron grandes diferencias entre los dos andamios al calcular la porosidad y la interconectividad (18% para el cemento y 23% para el vidrio), sin embargo en las reconstrucciones tridimensionales se observaron grandes diferencias en la distribución de los poros dentro de los andamios.
The characterization of biomaterials employs increasingly non-destructive imaging techniques. These techniques can be applied both in vitro and in vivo, with a resolution dependent on the size of the sample and the employed technique. One of the most used techniques, due to its high resolution, is the axial computer microtomography (μ-CT).
The objective of this study was to characterize scaffolds for tissue engineering in terms of its architecture and porosity using computer reconstructions from microtomography and to generate 3D meshes for finite element modeling. Images of two materials with different morphology were utilized. A scaffold of calcium phosphate cement and a scaffold of porous biodegradable glass were scanned with a resolution of 7.8 x 7.8 x 12.2 μm, to carry out subsequently a 3D computer reconstruction and meshing. The porosity was calculated and the interconnectivity was evaluated visually.
No relevant differences were found between the two scaffolds upon calculating the porosity and the interconnectivity (18% for the cement and 23% for the glass), nevertheless in the three-dimensional reconstructions large differences in the distribution of the pores inside the scaffolds were observed.
Los polímeros tipo elastina y su utilización como tags para la purificación de proteínas
Authors: Fernández-Colino A. , Girotti A. , López M.I. , Arias F.J. , Rodríguez-Cabello J.C. 
Published: August 2020

Actualmente, una de las técnicas más ampliamente utilizadas en la purificación de proteínas recombinantes es la cromatografía de afinidad. Sin embargo, esta técnica es costosa, requiere de equipo especializado y es difícil de escalar. Por tanto, es deseable el desarrollo de métodos más económicos y técnicamente más sencillos. Uno de estos métodos está basado en aprovechar las características termosensibles y el comportamiento inteligente de los polímeros tipo elastina (ELP) para purificar una proteína de interés. El bajo coste que esta metodología requiere permitiría disminuir el precio de diversas proteínas de interés biomédico en el mercado, con las consiguientes repercusiones que ello conlleva a la hora de su aplicación en clínica.
Por tanto, el presente artículo pretende indagar en la utilización de los ELP como tags para la purificación proteica, gracias al diseño y la producción de construcciones de fusión compuestas por la proteína diana de interés unida al tag elastomérico. Además se resaltarán otros efectos colaterales positivos que la presencia del ELP puede aportar a la proteína quimérica.
Currently, chromatography is one of the most commonly used techniques to achieve protein purification. Nevertheless, such technique requires specialized equipment and is difficult to scale-up. Therefore, the development of new, simpler and broadly applicable purification methods to circumvent these problems is desirable. One such approach takes advantages of the thermo-sensitive and smart behavior of the elastin like polymers (ELP) to purify the target protein. The low-cost of carrying out such methodology may permit us to decrease the price of diverse biomedical useful proteins, with the consistent impact that such fact entails when applying in clinic.
Therefore, the aim of this article is to clarify some aspects related to the use of the ELP as protein purification tags. For such use, it is necessary to design and produce fusion constructs between the target protein and the elastomeric tag. Moreover, apart from protein purification, further effects of the presence of the ELP in the fusion construct would be described.
