Comparison Of Three Numerical Methods For Estimating Weibull Parameters Using Weibull Distribution Model In Nigeria
Authors: Oyewole J.A. , Aweda F.O. , Oni D.
Published: July 2020

There is a crucial need in Nigeria to enhance the development of wind technology in order to boost our energy supply. Adequate knowledge about the wind speed distribution becomes very essential in the establishment of Wind Energy Conversion Systems (WECS). Weibull Probability Density Function (PDF) with two parameters is widely accepted and is commonly used for modelling, characterizing and predicting wind resource and wind power, as well as assessing optimum performance of WECS. Therefore, it is paramount to precisely estimate the scale and shape parameters for all regions or sites of interest. Here, wind data from year 2000 to 2010 for four different locations (Port Harcourt, Ikeja, Kano and Jos) were analysed and the Weibull parameters was determined. The three methods employed are Mean Standard Deviation Method (MSDM), Energy Pattern Factor Method (EPFM) and Method of Moments (MOM) for estimating Weibull parameters. The method that gave the most accurate estimation of the wind speed was MSDM method, while Energy Pattern Factor Method (EPFM) is the most reliable and consistent method for estimating probability density function of wind.

Published: July 2020

This study investigated the hypoglycemic and hypolipidemic effect of the oral administration of methanol extract of Hibiscus sabdariffa seed in alloxan induced diabetic albino rats. Two different doses (200 and 400 mg/kg) of the methanol extract of Hibiscus sabdariffa seed were administered daily to two groups of diabetic rats for a period of two weeks. Metformin (250 mg/kg) was given as the reference standard drug. Phytochemical, acute toxicity, fasting blood glucose, body weight, cholesterol, triglycerides and lipoproteins levels were determined using standard methods. Acute toxicity of methanol extract of Hibiscus sabdariffa seed was estimated to be greater than 5000 mg/kg body weight. There was an initial decrease in the body weight of the experimental animals after induction of diabetes which increased significantly (p<0.05) by the second week of treatment. The fasting blood glucose levels of the treated diabetic rats were significantly decreased at the second week of treatment with the group that received 400 mg/kg of extract recording the lowest fasting blood glucose level. The cholesterol, triglycerides and low density lipoproteins levels of the diabetic treated rats were significantly reduced while the high density lipoproteins level significantly increased. It can therefore be concluded that Hibiscus sabdariffa seed has the ability to lower blood sugar and maintain a stable lipid level.

A Bayesian Approach for Validation of Election Results
Authors: Ogundeji R.K. , Onyeka-Ubaka J.N.
Published: July 2020

Election process and results in many countries have resulted in both political and economic instability of that country. Fair and credible election process and results must be evidence-based and statistical proven. This study employed a Bayesian procedure for the validation of election results. Based on Nigerian 2011 and 2015 presidential election results, Bayesian credible intervals were obtained to assess the credibility of Nigeria presidential election results. The study explores Bayesian methods using a Bayesian model called beta-binomial conjugate model to compute posterior probability of electoral votes cast and confirm if these votes are within Bayesian credible intervals. The results obtained showed that election outcomes for the two major political parties in Nigeria 2011 presidential election are not within Bayesian credible bounds while 2015 presidential election results are within computed Bayesian credible bounds. Also, in contrast to frequentist approach, applied Bayesian methodology exhibited smaller variance which is an indication that Bayesian approach is more efficient. Thus, for election to be fair, credible and acceptable by the electorates, Bayesian approach can be used to validate electoral process and results.

Authors: Oriolowo O.B. , John O.J. , Abubakar D.S. , Jonah T.M. , Ismaila D.
Published: July 2020

Honey is sought globally for nutritional and therapeutic purposes because of the several chemical constituents that are abound in it. Some of these chemicals such as the anti-nutrients are defensive metabolic byproducts of plants from which bees obtained the nectars for honey production. This study was undertaken to determine the cyanide, oxalate, phytate, tannin and saponin compositions of honey samples from four North Central States of Nigeria. Anti-nutrients were analyzed following the Standards of Association of Official Analytical Chemists protocol for anti-nutrient compositions. Data obtained were compared using One-Way Analysis of Variance (ANOVA) and the means were separated using Fischer’s Least Significance Difference (LSD). The results showed that cyanide, phytate and tannin were present in all the four honey samples while oxalate and saponin were only present in two of the honey samples, though at varying concentrations each of them. All anti-nutrient except cyanide are within tolerable limit for human consumption. There were significant differences (p<0.05) in each of the anti-nutrient’s concentrations across the honey samples. The study showed that location and geographical region significantly influence honey’s anti-nutrient compositions as well as their concentrations.

Keywords: Honey, Anti-nutrients, Tannin, Saponin, Cyanide, Oxalate, Phytate.

The genus Acacia has been known to be a rich source of many secondary metabolites. This study was carried to isolate chemical constituents present in the stem bark of Acacia auriculiformis. The dichloromethane extract of the stem bark of Acacia auriculiformis was obtained by maceration. The extract obtained was subjected to silica gel column chromatography and preparative TLC. The isolated compounds were identified by spectroscopic analysis. This led to the isolation of ferulic acid ester (I), along with a steroid (II) and a triterpenoid (III). The structure of compound I was established using spectroscopic analysis (UV, IR, NMR and mass spectrometry) and identified to be dodecyl-4-hydroxy-3-methoxy-trans-cinnamate (I), compounds II and III were found to be á-spinasterol and lupenol respectively, based on the comparison of their spectral data NMR and MS with literature report. Compound I is being reported for the first time in the genus Acacia.

Published: July 2020

The study investigated persistence of urinary schistosomiasis and geohelminthiasis during MDA of anthelminthics. Information on supply and utilization of the anthelminthics from 2014 to 2017 were obtained from Ebonyi State Ministry of Health, Abakaliki, and from Ezza North LGA headquarters respectively. Urine and stool specimens were collected from 200 pupils from selected schools in Ezza North LGA. The specimens were examined using standard parasitological techniques. A total of 389,064 and 725,443 tablets of praziquantel and albendazole respectively were supplied to the study-area from 2014 to 2017. The percentage utilization of the regimen was 57.03% and 63.88% respectively. Age-dependent prevalence of schistosomiasis among the pupils indicated a total of 10.5%. Age group 9-11 years had least prevalence (6.15%) in comparison with others, with significant difference (p=0.044). Though the males were infected more than the females (11.96% vs 9.26%), no significant difference (p=0.535) was observed in prevalence of S. haematobium infections. Gender-related prevalence of soil-transmitted helminthiasis indicated no significant difference (p=0.224). Infection prevalence with respect to taxa of geohelminths indicated that hookworms had higher prevalence (24.50%) than A. lumbricoides (5%) and Trichuris trichiura (2.5%). Prevalence of the helminths were still high, despite appreciable levels of supply and utilization of the regimens. Surveillance for drug resistance is recommended.

Helminth parasitic infections of leaf litter frogs (Arthroleptis and Phrynobatrachus spp.) from cocoa plantations in southern Nigeria
Authors: Edo-Taiwo O. , Aisien M.S.O.
Published: July 2020

The endohelminths parasitizing leaf litter frogs (LLFs) at Ojo Camp, Ugboke, Ovia South West Local Government Area of Edo State, Nigeria were investigated. The frogs were collected from cocoa plantations (CPs) exposed to pesticides and from the village settlement (VS) located outside the pesticide use environment, for 15 months, using the Visual Acoustic Encounter Surveys method and disturbance searches. Two genera of LLFs were encountered: Arthroleptis (A. poecilonotus, A. variabilis, and six other undetermined Arthroleptis spp.) and Phrynobatrachus (P. auritus, P. plicatus, P. natalensis and Phrynobatrachus sp.). The overall prevalence of infection in LLFs from the CPs and VS were 37.4% and 50.0%, respectively but thedifference was not significant (p>0.05). The most parasitized LLF in the CPs was the unidentified Phrynobatrachus sp. (64.7%); in the VS infections were only recorded in A. poecilonotus (50%, n=4) and the single specimens of Arthroleptis sp. 2 collected from this habitat. The helminth parasites recovered included four cestodes (two adults: Cylindrotaenia jaegerskioeldi and Ophiotaenia sp.) and two larvae (two unidentified Proteocephalus spp.), three digenetic trematodes (two unidentified Mesocoelium spp. and a strigeoid larva) and eight nematode species (Amplicaecum sp.,  Aplectana sp., Cosmocerca ornata, Cosmocerca sp., Foleyellides sp., Physaloptera sp., Rhabdias sp. and an Ascaridida sp.). Although the cocoa plantations had very high species richness and diversity of parasites (15 parasite species), the intensity of infection was low. This generally low infection intensity reflects the inhibitory effects of the pesticide-contaminated environment of the CPs on parasite larval development and  transmission.

Intestinal helminth infection and malnutrition among public primary school children in Ibadan, Nigeria
Authors: Nnolim C. , Adekeye T.A. , Awobode H.O.
Published: July 2020

Intestinal helminthiasis associated with malnutrition in children remains endemic in developing countries despite considerable efforts at control. This study was carried out to determine the current prevalence status and the risk factors associated with intestinal helminth infections among primary school children in Ibadan. A cross-sectional study was undertaken among 5-16 year old pupils, from 7 primary schools in Ibadan, Oyo State. Microscopic examination of stool for ova was carried out using a formol-ether concentration technique. Predisposing risk factors were determined from questionnaire data while anthropometric indices consisting of weight, height and age were the measured indicators of the nutritional status. Of the 485 pupils examined, 187(38.6%) had helminth infections and the parasites identified were Ascaris lumbricoides (35.9%), Strongyloides stercoralis (12.4%), hookworm (8.5%), Enterobius vermicularis (4.9%), Schistosoma mansoni (3.5%) and Trichuris trichiura (0.4%). More male pupils (52.9%, p = 0.05) than females (47.1%) had infections. Pupils aged between 9-12 years (p = 0.02) had highest (49.2%) infection rates. Infections were recorded in 13(18.57%) of 70 pupils treated with levamisole by the local health centres 2 weeks prior to this study. Wearing of footwear, parent’s occupation, drinking water sources, family size and toilet type were risk factors significantly associated (p<0.05) with infection in this study. The  overall prevalence of wasting, stunting and underweight were 24.4%, 28.8% and 7.8% respectively, there was however, no statistical relationship (p>0.05) between the prevalence of infection and malnutrition. Intestinal helminthiasis is still prevalent in schoolchildren despite targeted  chemotherapy. It is therefore suggested that chemotherapy should include all children in the communities along with continuous enlightenment to ensure the disruption of parasite transmission.

Behaviour and stress in three breeds of laying hens kept in the same environment
Authors: Rozempolska-Rucińska I. , Czech A. , Kasperek K. , Zięba G. , Ziemiańska A.
Published: July 2020

The aim of the study was to determine whether birds of different breeds, with different preferences for environmental elements and kept in identical conditions, would exhibit different behaviour and stress levels. The research material consisted of 50 laying hens of the Green-legged partridge (Zk), Polbar (Pb), and Leghorn (Lg) breeds. The birds were provided with identical environmental conditions. They were kept on litter in separate boxes, with 25 individuals of one breed per box, in the same building. An open field test was used in determining the behaviour of the birds. Levels of cortisol in serum and corticosterone in feathers were evaluated, and haematological and biochemical analyses of blood were performed. Leghorns proved to be a highly excitable and active breed whose needs cannot be fully satisfied in the standard conditions of large farms. Based on a differential leukocyte count, their hyperactivity was associated with increased stress. The Green-legged partridge exhibited the lowest stress levels. Birds kept in the same environmental conditions were found to differ significantly in the level of stress, probably because of differences in their behavioural needs and the possibilities of satisfying them. To reduce stress levels and improve the welfare of hens, it is necessary to verify their preferences first. Stress indicators are elevated in highly excitable birds, and the conditions on large farms are not conducive to meeting their behavioural needs.

Published: July 2020

AbstractThe objective of this study was to assess the nutrient contents and in vitro true digestibility (IVTD) of parts of the corn plant. The corn used in the study was P2088, a variety that is grown widely in Turkey. It had matured and was harvested 140 days after planting. Four replicate plants were separated into nine parts, namely lower stalk, central stalk, upper stalk, corn ear stalk, corn ear shuck, kernels, corn cob, leaf, tassel, plus the entire plant. The samples were dried and ground for analysis. Nutritional values were determined in the laboratory and in vitro digestibility was assessed. Significant differences in nutrient content were observed among parts of the corn plant. The highest crude protein (CP) content was found in the leaf (12.41%), followed by the grain (12.37%). Dry matter (DM) varied from 91.25% to 96.07%. The highest ether extract (EE) was in the grain (2.84%), and the upper stalk contained the least EE (0.29%). The parts also differed in their contents of crude cellulose (CS) and crude ash (CA) (P <0.001). Most organic matter (OM) was found in the corn cup (94.27%). The highest in vitro dry matter digestibility (IVDMD) was in the kernels (79.06%) and the lowest was in the lower stalk (38.13%). In terms of in vitro true organic matter digestibility (OMD) values of the corn plant and its 9 parts, the highest values were found in the kernels and the lowest in the lower stalk.Keywords: crude nutrients, in vitro true digestibility, parts of corn plant

Published: July 2020

The effect of dietary genistein on performance, intestinal morphology, caecal Lactobacillus spp. count, and tibia composition in broiler chickens after 21 and 37 days of feeding was investigated. A total of 360 Cobb 500 broiler chickens (21 days old) were randomly allocated to five treatments with six replicates of 12 birds each. They were fed a basal diet (C) or a basal diet supplemented with 200 (T1), 400 (T2), 600 (T3) and 800 (T4) mg genistein/kg of feed. Genistein supplementation did not affect feed intake, but improved bodyweight, weight gain and feed conversion ratio (FCR) after 21 days, while 600 mg/kg led to a significant increase in FCR after 37 days of feeding. Plasma triglyceride level decreased with dietary genistein after 21 days, while increases were found in T3 and T4 groups after prolonged supplementation. Significantly improved duodenal and jejunal villus length and width, crypt depth and villus/crypt ratio were observed after the first and the second finishing periods, respectively, while adverse effects were found in the ileum for both periods. At 42 days old, greater spleen and heart weights were measured in broilers fed diets with 800 mg/kg than in other broiler groups. The shorter genistein supplementation period (21 days) of 200 and 400 mg/kg had a positive effect on tibia wet weight, ash and calcium (Ca) content, while 37 days of the higher genistein doses administered to the T2, T3 and T4 birds significantly increased caecal lactic acid bacteria (LAB) counts. Thus, recommended doses should not exceed 400 mg/kg.

Published: July 2020

The aim of this study was to evaluate the influence of dietary linseed oil and antioxidants on the quality of fresh and frozen pork neck stored at -20 °C for six and 12 months. Polish Landrace x Duroc pigs were fed a standard diet (C), a diet supplemented with 3% linseed oil (L1), or a diet with 3% of linseed oil, 1 mg organic selenium (SE)/kg, and 100 mg vitamin E/kg (L2). Chemical components, fatty acid profile and vitamin E content were determined in the fresh meat. Colour, pH and change in the profiles of certain volatile compounds (alcohols, aldehydes, ketones, and esters) were monitored during frozen storage. An electronic nose technique, which was based on ultra-fast gas chromatography, was used to evaluate changes in the profiles of the volatile compounds. After six months of frozen storage, oxidative processes were slower and similar in groups L1 and L2, but less so in meat from C. In pork that was stored for six months, lipid oxidation was not affected by supplementation only with linseed oil (L1). After 12 months of frozen storage, a reduced rate of increase in alcohols, aldehydes and ketones was observed in pork from L2 relative to L1 and C. Lipid oxidation processes in long-stored frozen pork neck were inhibited by the addition of antioxidants to L2. However, a total colour change (ΔE*) of the pork from L1 and L2 was found during storage, which might influence consumers’ decisions to purchase the product.Keywords: colour, fatty acids, freezing, meat quality, volatile components

Este trabajo analiza el desempeño relacional como dimensión clave para medir la calidad de vida en prisión. Se entiende por dicho desempeño el que se desprende de la valoración que los internos hacen de las relaciones y el trato dispensado por el centro penitenciario y su personal en conjunto, y del proporcionado en particular por el personal de vigilancia y el personal de tratamiento. Se ha realizado una encuesta entre 2017 y 2018 a una muestra de 102 personas que cumplen condena en el Centro Penitenciario Sevilla II. El cuestionario utilizado es una adaptación al contexto español del Measuring Quality of Prison Life (MQPL) desarrollado por Alison Liebling desde el Prison Research Center. Los resultados confirman que en la valoración de la calidad de vida que hacen los presos resultan determinantes el trato que se recibe y sus relaciones con los funcionarios de vigilancia, por un lado, y el personal de tratamiento, por otro.

Recovered and Restored? Abducted Women in 1947 Partition Narratives
Authors: Aslam Saiyma
Published: July 2020

During the Partition of India in 1947, communal riots triggered unspeakable acts of horror against women of rival communities. A large number of women were abducted; some were later recovered and returned to their families. The trauma suffered by these abducted women and survivors extends all proportions. This paper analyses the dislocation, pain and trauma of abducted women, as depicted in two short stories: The Lost Ribbon by Shobha Rao (2016) and Banished (1998) by Jamila Hashmi originally published in Urdu as Banbas (exile) in Aap-Beeti, Jag-Beeti (1969). I consider the abducted women’s plight in view of the distinction Giorgio Agamben made of zoè (bare life) and bios (political life as a citizen) in Homo Sacer: Sovereign Power and Bare Life (1998) and The Use of Bodies (2015). I analyse how Partition reduced women to bare life, despite offering them hopes of life as a citizen of their respective independent countries. In this regard, I discuss their sufferings and trauma due to double dislocation, first stemming from rape, abduction and captivity in the wake of communal violence, and second due to the nature of the states’ intervention in their recovery and rehabilitation.  My analysis also shows that recovery of abducted women should not be taken as synonymous with restoration because restoration of a traumatised human being to her pre-abduction state of mind and life is not possible.
Drug Addiction and Alcoholism Among Sexually Abused Women in Pakistan
Authors: Ali Sheraz , Tariq Muhammad
Published: July 2020

The study aims to identify factors which contribute to the prevalence of alcoholism and drug addiction among sexually abused women in an ultra-conservative society. A qualitative research design is used in conjunction with interviews from women and physicians, categories which included both psychiatrists and sexologists, across six districts of Khyber Pakhtunkhwa. The phenomena of drug addiction and alcoholism were more pronounced in victims working for the commercial sex sector. The findings suggest Post-Traumatic Stress Disorders (PTSD) as a driving factor of alcoholism and drug abuse, which in turn cascades into secondary and tertiary levels of trauma. Sexual victimization and re-victimization, familial rejection, stigmatisation and social degradation were contributing factors to relentless stress. Drugs in vogue among victims were Valium-two (Diazepam) and Lexotanil that contained Bromazepam. Hashish and alcohol were consumed sparingly by victims, while the use of cocaine and heroin was absent due to severe masculine perceptions and addiction. The study contributes to a better understanding of a socially-excluded, economically-disadvantaged and stigmatised group by taking a pro-feminist stance to advocate for the rights of victims.
ASSESSMENT OF HEAVY METALS LEVELS IN SOIL AND VEGETABLES IN THE VICINITY OF UNLINED WASTE DUMPSITE IN NNEWI, ANAMBRA STATE NIGERIA
Authors: Aralu C.C. , Okoye P.A.C.
Published: July 2020

Unlined waste dumpsites are known to generate pollutants in the environment where they are located. This study investigates the pollutant load of unlined dumpsite by assessing the heavy metals levels of soil and vegetables in and around the waste dumpsite. 16 samples (study samples and control) for each soil and vegetable samples (Telfairia occidentalis, Talinum triangulare and Amaranthus hydridus) were collected respectively during wet season. The levels of 10 heavy metals were analysed using Atomic Absorption Spectrophotometric method. The highest and lowest heavy metals concentrations in the study sample site for vegetables ranged from 11.5 mg/kg – 0.01 mg/kg, while 7.79 mg/kg - 0.00 mg/kg was analysed for control site. The soil heavy metals values ranged from 13.1 mg/kg – 0.28 mg/kg for study samples, while 7.45 mg/kg – 0.02 mg/kg for control site. The study samples heavy metal results for vegetables and soil were higher than the control samples, which was attributed to high mobility of metal ions as a result of its closeness to the dumpsite through leaching. The total transfer factors ranged from 3.89 – 3.01 for study samples and 3.46 – 2.75 for control samples. The study samples were higher than the control site due to high levels of soil contaminations. The vegetables samples showed high levels of heavy metals, which were above WHO/FAO limits. The risk index range of 16.015 – 14.551 for study samples, and 6.821 – 5.761 for control samples from the extrapolated vegetable results, revealed that the vegetables collected from both sites were above the critical value of 1. The vegetables are unfit for human consumption and can cause non-cancer health risks to the populace who consume them. A proper refuse disposal system in and around the residential areas should be adopted. Routine monitoring of heavy metals in such plants to prevent excessive accumulation of the metals in the food chain is also advocated.
Biosorption of Pb(II), Ni(II) and Cd(II) ions from aqueous phase by Ceaser weed (Urena Lobata) bark, a low cost biosorbent.
Authors: Amadi O. K. , Okoyeagu A. , Akoh O. U.
Published: July 2020

In this study, an effective biosorbent was developed from Urena Lobata for removing Pb2+, Ni2+, and Cd2+ from its aqueous solution. Different experiments were conducted in a batch system to determine the effects of the system variable such as biosorbent dosage, initial metal concentration range of 10 to 50 mg/L, and temperature. The uptake capacity and distribution coefficients (Kd) were determined for the adsorption system as a function of sorbate concentration. The equilibrium adsorption data were analysed by the Langmuir, Freundlich, Tempkin, and Dubinin Radushkevich (DKR) isotherm models but Dubinin–Radushkevich best interprets the experimental data. The maximum adsorption capacity of Ni(II), Pb(II), and Cd(II) are 0.00 mg/g,333.33 mg/g and -52.63 mg/g respectively. Different thermodynamic parameters, like Gibbs free energy (∆G), enthalpy (∆H), and entropy (∆S) of the adsorption process have also been evaluated. The negative value of G indicates the feasibility of the process. The positive value of H: 21026.11, 6927.23, and 6815.82 J/mol for Ni(II), Cd(II) and Pb(II) ions respectively confirms the endothermic nature of adsorption. Moreover, the positive value of S: 87.55, 59.65, and 6.90 J/mol for Ni(II), Cd(II), and Pb(II) ions respectively observed for the adsorption of metal ion molecules suggested the increased randomness at the solid-solution interface during the adsorption process. According to the equilibrium studies, the selectivity sequence is given as Pb2+ > Ni2+ > Cd2+. These results show that Urena Lobata holds great potential to remove cationic heavy metal species from industrial wastewater.
Gerçeğin Yeniden İnşasında Tiyatroda Gündelik Dilin Kullanımı
Authors: KARABULUT Tufan
Published: July 2020

Antik Yunan tiyatrosundan başlayarak 18. yüzyıla kadar uzanan süreçte, tiyatronun dili şiirsel ve ölçülüdür. Tragedyaların düzyazı diliyle yazılması gerektiğine dair ilk ciddi tartışmalar Fransa’da Trublet, Fontenelle ve La Motte gibi yazarlar tarafından ortaya atılır. Ama bu konuda asıl büyük etkiyi İngiliz oyun yazarı George Lillo’nun 1731’de yazdığı The London Merchant (Londra Taciri) adlı eseri yapar. Lillo’nun bu girişimi, Diderot ve Lessing’in çabalarıyla Kıta Avrupası’nda harekete geçirici bir etkiye sahip olur. Dram sanatındaki bu düşünsel ve yazınsal dönüşümün temelinde burjuva sınıf bilincinin gelişimi yatar. Orta sınıf seyirci tiyatroda üstün trajik kahramanları izlemek yerine kendi yaşamından günlük olayları ve sıradan kişileri görmeyi daha gerçekçi bulur. Böylelikle tiyatro sanatında kendine özgü yeni bir biçim ve anlatım tarzı yaratan burjuva sınıfı, oyun yazımında da gündelik dilin kullanılmasıyla tiyatroya farklı bir gerçeklik algısı kazandırır. 19. yüzyıla gelindiğinde realizmin ve natüralizmin etkisiyle tiyatronun hakîm dilinin düzyazı olduğu görülür. Bu makalede, öncelikle, oyun yazımında koşuk dilinden düzyazı diline geçişin tarihsel süreci incelenmiş, ardından da tiyatroda gündelik dilin kullanımının gerçeklik algısına katkıları değerlendirilmiştir. Son olarak, diyalog yazımının geçirdiği bu değişimle düzyazı dilinin tiyatro-edebiyat ilişkisine kazandırıp kaybettirdikleri üzerinde durulmuştur.

Também foi notável o desenvolvimento de habilidades cognitivas extremamente necessárias para se viver em um mundo digitalizado como o momento atual além de desenvolver competências fundamentais para a cidadania.
O ensino de nutrição e metabolismo energético a partir de um jogo de tabuleiro denominado Sobrevivência “Versão 1.0”
Authors: Vasconcelos Thyago Santos , Da Poian Andrea Thompson
Published: July 2020

O estudo de nutrição e metabolismo energético no ensino médio depende de uma série de conceitos da química orgânica, que somente será trabalhada no último ano pelo professor de Química. A grande dificuldade dos professores de Biologia é introduzir esses conceitos químicos paralelamente a esse conteúdo. Cremos que apenas as aulas expositivas não sejam suficientes para despertar o interesse dos alunos. Partindo dessa premissa, acreditamos que seja muito relevante o desenvolvimento de novos materiais educacionais com o intuito de melhorar a aprendizagem. “Sobrevivência” é um jogo de tabuleiro de caráter investigativo/cooperativo sobre nutrição e metabolismo energético. Usado como uma estratégia lúdica, ele foi desenvolvido como material pedagógico para auxiliar os professores a revisar conceitos sobre o tema.

Authors: Moura Francisco Nunes de Sousa , Leite Raquel Crosara Maia , Bezerra José Arimatéa Barros
Published: July 2020

Considerando a relevância de discussões voltadas à Educação Alimentar e Nutricional (EAN), objetivou-se neste trabalho averiguar as produções relacionadas à alimentação saudável em vieses de currículo escolar, formação de professores e estratégias didáticas no Ensino de Ciências/Biologia. Para isso, realizou-se uma revisão de literatura nas edições do Encontro Nacional de Ensino de Biologia e da Revista de Ensino de Biologia, visto os seus protagonismos em discussões no campo das Ciências Naturais. Dos quarenta artigos identificados, teve-se publicações voltadas ao currículo escolar (1), à formação de professores (11) e a estratégias didáticas (28), remetendo a EAN em diversos contextos. Assim, tal temática tem sido discutida na educação em ciências, propiciando uma melhor formação dos sujeitos escolares – licenciandos, professores e alunos.
Entre encontros e ensino de biologia e gêneros e sexualidades: sopros e insurgências de uma biologia menor

Published: July 2020

Este artigo apresenta dados de uma pesquisa cartográfica que se interessou pelasressonâncias das experiências de pessoas transaos territórios da educação em Biologia e que se materializou num caminhar entreos emaranhados do campo oficial do ensino de Biologia. Nesse contexto, temos como objetivo apresentar as potencialidades e as insurgências de um mapeamento dos movimentos efetuados nos ENEBIO’s e EREBIO’s. O sopro dos encontros nos convocaram ao agenciamento “Experiências de pessoas trans – Ensino de Biologia” que nos abriu espaços para pensarmos a educação em biologia enquanto territórios constituídos por linhas de diferentes naturezas, ritmos e direções, e, em que os gêneros e as sexualidades ecoam e funcionam na sua constituição, produzindo planos que coexistem em oscilações maiorese menores.

Published: July 2020

O artigo apresenta e discute uma iniciativa promovida pela Regional 2 (RJ/ES) da Associação Brasileira do Ensino de Biologia (SBEnBio) para compreensão das práticas de ensino de Ciências e Biologia desenvolvidas por docentes durante o isolamento social determinado pela pandemia de COVID-19 no período compreendido entre março e abril de 2020. Aplicamos um questionário on-line a 187 respondentes. Os resultados indicam que demandas metodológicas sobre planejamento, avaliação e estratégias didáticas constituíram os principais desafios nesta conjuntura. Destaca-se também o aumento da carga de trabalho e as dificuldades de acesso à internet de seus estudantes. Concluímos que é um momento árduo para a maioria dos docentes, mas que associações como a SBEnBio podem criar espaços para reflexão sobre essas práticas.

Authors: Perroni Gasull Candela , Sago Herrador Emilia , Belén Martín Rocío
Published: July 2020

El siguiente trabajo es abordado desde un enfoque etnográfico, y tiene como propósito conocer aspectos relevantes del aprendizaje co-construido a través de prácticas agrícolas en el contexto informal de una huerta, ubicada dentro del territorio de una universidad nacional de Argentina, configurada de forma autónoma y horizontal. A través del análisis de las narrativas de los huerteros que participaban con regularidad en la huerta, se elaboraron categorías de análisis sobre los rasgos predominantes del aprendizaje agroecológico, a saber: (1) trayectorias de los participantes, (2) aprendizaje como práctica comunitaria, (3) aspectos personales del aprendizaje, (4) prácticas generadoras de aprendizaje y (5) dimensión política-social.
OS MEIOS INOVADORES E A TERRITORIALIDADE

Published: July 2020

O presente artigo pretende analisar mediante revisão bibliográfica das principais teorias, a relação entre as nuances dos meios inovadorescomo ferramenta de promoção do desenvolvimento, sua correspondênciacom as teorias endógenas e exógenas de desenvolvimentoregional e sua capacidade de contribuir/inibir as potencialidades produtivasde território. Buscar entender os meios inovadores como formade encontrar alternativas de promoção do espaço sem se submeter aomainstream das correntes econômicas hegemônicas. Para determinar alinha norteadora desse estudo, parte-se da hipótese que não existe inovaçãoque não esteja ancorada em práticas e, portanto, que não estejasituada no espaço. Nos estudo visualizou-se que as dinâmicas territoriaissão amplamente afetadas pela lógica produtiva, lógica essa que quandoorganizada pela dinâmica funcional, tende a gerar mais desequilíbrio entreos territórios, pois exigem atributos que esses espaços não possuem,desencadeando um processo de dominação de caráter homogeneizante.A alternativa seria a busca por uma dinâmica embasada em uma sériede arranjos endógenos capazes de inovar e através desta promover umsistema de competição via diferenciação.

Published: July 2020

This study was carried out among pupils of three primary schools in Dawakin Kudu Local Government Area of Kano State, Nigeria between May and July, 2018. Three hundred and twenty (320) pupils were examined for the presence of schistosome eggs in urine. Out of the 320 pupils examined only 34 (10.6%) were found to be infected with S haematobium. Males have higher prevalence of 26 (12.1%) compared to females 8(7.6%). The age group 8-10 years has the highest infection rate 13 (15.85%) while the age group 5-7 the least with 1(4.6%). Although sample sizes were not equal, among the communities Fallau with 65 has the highest infection rate with a prevalence of 11(16.9%), Gano with 135 has 14 (10.4%) followed by Danbagina, 120 with a prevalence of 9(7.5%). All infections were light (<50eggs/10ml of urine).There was a significant difference in infection among the different villages examined χ2= 8.94, df = 2, p<0.05.Statistically there was also a significant difference in infection among the different age groups χ2= 2.9356, df = 3, p<0.05. It was concluded that S. haematobium is present in these study areas and unless health education on the mode of transmission of the disease, provision of safe and adequate water supply and sanitation which will help in curtailing the infection is provided, there is the likelihood of a rise in infection rate. This is the first time this type of study was carried out in these study areas.

Published: July 2020

The study was conducted to evaluate the principal component analysis of phenotypic attributes of West African Dwarf (WAD) goat. Data collected on the live body weight and twelve morphometric traits of the goats which were categorised into four age groups based on their dentition. The age groups were: less than 2years old, 2- 3years old, 3-4 years old and 4 years old. The data were subjected to a PCA and Cluster analyses using the multivariate procedure components of SAS (2003). Result revealed that highest values of morphometric traits were obtained in goats that of 4 years old. The rate of increase in body weight and other morphometric traits was high in age group of ˂2 years to age 2-3years compared to differences observed in others across the age group. Heart Girth had the highest correlation with body weight. Foreleg, neck, ear and hind leg lengths; wither height and rump height were weakly correlated with the body weight of the goats. Result revealed that two Principal components were retained in the first age group (age group˂2years) which accounted for 72.99% of the total variation. The first PC alone accounted for 63.13% of the total variation while PC2 accounted for the remaining 9.86%. From this study, it was concluded that there is interdependence among body weight and morphometric traits and that morphometric traits can be used in predicting live weight of WAD goats; PCA and Cluster could be exploited in breeding and selection programmes to acquire highly coordinated animal bodies using fewer measurements.

Published: July 2020

Traditional housing fabrics are an obviously valuable heritage to be reviewed and analyzed, as they present the right pattern for native architecture because it is considered the main core in the creation of cities, as well as the architectural elements and buildings located in them. The objective of this study is to review and recognize the physical and social behavior patterns of these buildings to improve these valuable fabrics and save them from their presence of unusual buildings. First, this study would review the key problems on the design of patterns in the architecture of the house, obtaining an analytical-descriptive point of view; This research first reviews the key issues of the patterns in the architecture of the house, and then identifies the physical components that are effective in traditional buildings, contrasting with the theoretical foundations obtained. The next step has been the identification and physical review using the field research method to physically identify and review the case study buildings in the historical fabric. After the analysis, the most effective physical components would be prioritized by hierarchical method. Finally, considering the results obtained, not only the principles of native architecture are identified, but also some approaches are introduced to improve the relationship between physical behavior environments in the Niakie neighborhood in Amol.

Published: July 2020

Globalization, accompanied by a continuous increase in competition, complicates the conditions for the development of market relations in the Russian Federation. The priority development territories should have functioned as a tool for industrial and productive reform. These territories and their special economic zones should have become territorial centers of innovative and industrial development. However, it does not happened. The article analyzes some of the main reasons for this situation in Russia.
Illegal economic phenomena in the Russian agricultural sector
Authors: Yarkova Tatyana M.
Published: July 2020

The current unstable market situation in Russia forces undesirable measures to be taken, mainly in the field of tax legislation for economic entities in the agricultural sector. This becomes a prior factor for the development of economic crime and the development of illegal phenomena. In recent years, there has been an increase in these crimes in the country. The agricultural sector of the Russian economy, as well as other countries, requires the availability of state financial support. However, during almost the entire post-Soviet period, a partial theft of state funds allocated to support and develop agricultural sectors can be observed under free market conditions. Such a problem exists everywhere in Russia. Existing methods of supervision and control over the use of budget allocations do not give the expected effect. In the context of such a negative situation, there is a need to develop effective methodological tools to assess the effectiveness and integrity of the use of budget funds for the agricultural sector, the algorithm of which is quite accessible and involves the use of scientific and practical methods, experience and knowledge of experts in the field of agriculture. This article aims to identify patterns of economic crime in agricultural and livestock production, and to propose methods for the evaluation and monitoring of public funds to Russian agricultural entities.
Visión y revisión de artículos científicos sobre temática agrícola en la Revista Amazonía Investiga
Authors: Arbeláez-Campillo Diego Felipe , Rojas-Bahamón Magda Julissa
Published: July 2020

En las economías globalizadas el desarrollo del agro constituye una pieza clave dentro de las estrategias para superar la pobreza, minimizar el latifundio y reducir la conflictividad social, en un marco de política públicas que fomentan el uso y explotación racional de los recursos naturales. Por estas razones, la producción de artículos arbitrados en una perspectiva multidisciplinaria en el ámbito temático de la agricultura, ocupa un sitial destacado en las revistas científicas de alto impacto de mayor difusión internacional. El objetivo de esta investigación es revisar una muestra de la producción científica sobre agricultura publicada en la revista Amazonia Investiga en el periodo 2019-2020. Para procesar la información recabada se optó por la metodología documental y por la técnica del balance bibliográfico, como condición de posibilidad para develar lo que se ha escrito y como se ha escrito sobre la materia. A modo de conclusión, se evidencia que se producen saberes sobre el agro desde disciplinas tan diversas como: el derecho, la economía, la ciencia política y la agronomía, entre otras, lo que demuestra que se trata de un tema multidimensional que no puede ser abordado en todo su alcance desde una única perspectiva disciplinar, teórica o metodológica.
