Published: August 2021

Em uma perspectiva contemporânea a nanociência tem crescido nas questões ambientais, diante deste cenário vamos incluir o estudo desta ciência aos alunos do Ensino Médio de escolas públicas do Estado de São Paulo. É importante que todos saibam o quão a ciência vem se desenvolvendo nos últimos anos, e que a nossa realidade no cotidiano escolar não está dispare dessas evoluções pois a nanotecnologia está em nossas vidas de maneira intrínseca e pouco observada pela sociedade de maneira geral. Por fim, é importante valorizar as questões ambientais independentemente dos estudos, pois o princípio de desenvolvimento sustentável está amarrado nos pilares da ciência, tecnologia e meio ambiente. Representando o tema Energia, meio-ambiente e sociedade, eu escolhi essa matéria do correio brasiliense que se refere as plantas bioiluminecentes, através de nanotubos, que caracterizam bem o tema, segue o resumo: Pesquisadores inserem nanotubos em folhas e aumentam a capacidade de fotossíntese de vegetais, que, no futuro, poderão ser usados como biossensores ambientais e fontes de iluminação em estradas

Authors: DOS SANTOS CAETANO FARIAS LUCIANA
Published: August 2021

Para ser professor de Educação Infantil deve se ter um olhar instrumentalizado e potencializado para perceber na escuta um “canal” que, se bem exercido, poderia dar voz e vez às crianças e aos bebês e mostrá-los como seres potentes, únicos e protagonistas do próprio aprendizado. Dessa forma, o objetivo desse artigo é refletir sobre a segurança afetiva na creche e desenvolvimento saudável de bebês e crianças pequenas enquanto instrumento metodológico que colabora para o protagonismo infantil e que, inclusive, ajuda revelar a visão de infância do docente. A metodologia usada consiste em pesquisa bibliográfica. Uma escuta a partir das demandas infantis e atuação junto aos bebês e crianças. O estudo permite concluir que é fundamental que esses atores não sejam marcados pela concepção de um “vir a ser”, que a escuta está implicada nessa dinâmica e é um ponto crucial nesse processo.

CONTRIBUIÇÕES DA PSICOPEDAGOGIA A LUZ DA PSICANÁLISE SOBRE AS CRIANÇAS QUE NÃO LÊEM E NÃO ESCREVEM
Authors: MENDES DE OLIVEIRA LOPES MIRIAM
Published: August 2021

Este artigo traz como temática algumas reflexões acerca dos processos educativos, nomeadamente a não aprendizagem de leitura e escrita sob o olhar psicanalítico. Versará sobre a identificação das angústias e medos presentes nessa relação ora objetiva ora subjetiva. Permeará sobre a importância da história pessoal e da compreensão dos significados e motivos, conscientes e inconscientes, inerentes a todos os percalços que geram a falta, o concebimento deste ser, por hora não desejante por ler e escrever. Nosso ápice é procurar entender o problema de aprendizagem decorrente da falta de desejo da criança em aprender a leitura e escrita. Visto que a escola é o primeiro canal formal em que os conhecimentos de leitura e escrita são colocados em maior grau de evidência. Teremos como aporte teórico a Psicanálise com base em Freud, Leda Barone Alicia Fernandez, Sara Pain uma vez que a Psicopedagogia irá procurar interpretar o significado da situação traumática que está escondida por trás do significado simbólico. Ela irá garantir espaços para a manifestação simbólica dos significados inconscientes. Também, tentará compreender a lógica que mobiliza a formação da estrutura sintomática enquanto linguagem, possibilitando que o sujeito se constitua enquanto autor capaz de desfrutar do prazer de pensar. O estudo e compreensão do papel motivações e intenções foram contributos significativos destes autores. Em todos eles é comum a preocupação com uma abrangência do desenvolvimento do sujeito, a busca da totalidade e do sentido individual, a valorização das experiências subjetivas, a necessidade do estabelecimento de relações e a importância das experiências intersubjetivas. Conclui-se, que a abordagem psicanalítica tem muito a acrescentar aos estudos da Psicopedagogia, uma vez que propõe um trabalho no âmbito da subjetividade, devendo ir além da escola, na oportunidade de se possibilitar um espaço para que a criança possa pensar, ou seja, um espaço de autoria de pensamento.

A IMPORTÂNCIA DAS BRINCADEIRAS NA EDUCAÇÃO INFANTIL
Authors: MONTÓRIO DA SILVA REYES ROSANA
Published: August 2021

A brincadeira é uma linguagem natural da criança e é relevante que esteja presente na escola desde a educação infantil para que a criança possa se conduzir e se manifestar através de atividades lúdicas – considerando-se como atividades lúdicas as brincadeiras, os jogos, a música, a arte, a expressão corporal, ou seja, tarefas que mantenham a espontaneidade das crianças. O brincar é fundamental na construção do conhecimento do sujeito com o objeto. Por meio das atividades lúdicas, a criança exterioriza seus sentimentos desde a relação concreta que ele estabelece com o meio em que vive até a interação com os outros. Com o gesto lúdico, a criança constrói um mundo de imaginação a partir do mundo real: o seu mundo de faz de conta. Esse mundo nada mais é do que a aprendizagem do modo do ser humano em um essencial estágio de sua existência: a infância.

Published: August 2021

Neste artigo pretendeu-se traçar, por meio de revisão bibliográfica e análise qualitativa, um paralelo entre o desenvolvimento infantil e a música, fazendo um estudo sobre os conceitos de ambos e de como a música contribui de maneira lúdica e significativa para o desenvolvimento infantil em todos os seus aspectos. Ao discorrer sobre a música e a sua trajetória dentro do currículo escolar, percebe-se que, apesar de sua inquestionável importância para o desenvolvimento, ainda é uma área pouco valorizada, uma vez que é possível verificar uma tendência de que a prática da utilização do recurso musical na Educação Infantil se dá de maneira informal e pouco subsidiada por fundamentações teóricas, efetivada por ações individuais e experimentalistas.

The Role of Alcohol Consumption and Smoking Habits in Increasing the Diabetes Mellitus Risk in Adult Men and Women with Central Obesity in Indonesia
Authors: Setyaji Diyan Yunanto , Purnawijayanti Hiasinta Anatasia
Published: August 2021

Central obesity is more predictive of measuring the risk of type 2 diabetes compared to anthropometric indicators of general obesity. The results of previous studies are still inconsistent and the causal relationship that had not been well explained between the determinant factors and the increasing incidence of diabetes mellitus. This study aims to determine the relationship between alcohol consumption and smoking habits in increasing the risk of diabetes mellitus in adult males and females who are central obesity in Indonesia. The analysis presented in this study was based on the data from a population-based, cross-sectional, nationally representative survey (Indonesian Basic Health Research 2018/RISKESDAS 2018). In total, 12726 men and 18637 women aged 18–65 years were enrolled. A validated questionnaire, smoking card, and alcohol card were used for the assessments. There was a significant difference (p <0.000) in the proportion of diabetes mellitus incidence between men and women in both age groups who consumed less than 1 pack of cigarettes or more than 1 pack per day. The age difference for the sexes did not show a statistically significant association with alcohol consumption of either under 5 servings or above 5 servings per day for the incidence of diabetes mellitus. Women with central obesity had an adjusted prevalence ratio of 1.7 times higher for diabetes mellitus than men. There were negative multiplicative interactions between sexes and smoking status (interaction PR = 0.685; 95% CI = 0.52-0.88) and cigarette exposure (0.65; 0.52-0.80) in women. The effects of alcohol consumption and their interactions with sex did not have a significant relationship. There is an increased risk of diabetes mellitus especially in women with central obesity. Alcohol consumption by people with central obesity has an interaction with gender in an increased risk of diabetes mellitus which is higher in women than men.
Toen en nu: heeft het gevangeniswezen de middelen om zijn doelen te bereiken?

Then and now: Does the Dutch prison system have the means to achieve its goals?

Starting point in this article is the classical work of Herman Franke on the history of the Dutch prison system. Franke showed how policymakers and other people who influence prison policy and practice tried to reduce criminal behavior in the past two centuries. These attempts had various backgrounds, among which religious, sociological and biological, and varied greatly in scientifical substantiation. Every new prison policy elicited high hopes, but in practice criminal behavior was rarely pushed in the desired direction. The means of the prison system, among which staff, buildings and regime regulations, showed to be much later realized than the formulated goals established by law. Another problem that came up more than once in history was that the urge and compulsion mechanism of a new prison policy lacked support base and (agogical) skills among prison staff. Recommendations are formulated for the (near) future in favor of more successfull prison policy implementations.

Alteration of TGFB1, GDF9, and BMPR2 gene expression in preantral follicles of an estradiol valerate-induced polycystic ovary mouse model can lead to anovulation, polycystic morphology, obesity, and absence of hyperandrogenism
Authors: Asghari Reza , Shokri-Asl Vahid , Rezaei Hanieh , Tavallaie Mahmood , Khafaei Mostafa , Abdolmaleki Amir , Majdi Seghinsara Abbas
Published: August 2021

Objective: In humans, polycystic ovary syndrome (PCOS) is an androgen-dependent ovarian disorder. Aberrant gene expression in folliculogenesis can arrest the transition of preantral to antral follicles, leading to PCOS. We explored the possible role of altered gene expression in preantral follicles of estradiol valerate (EV) induced polycystic ovaries (PCO) in a mouse model.Methods: Twenty female balb/c mice (8 weeks, 20.0±1.5 g) were grouped into control and PCO groups. PCO was induced by intramuscular EV injection. After 8 weeks, the animals were killed by cervical dislocation. Blood serum (for hormonal assessments using the enzyme-linked immunosorbent assay technique) was aspirated, and ovaries (the right ovary for histological examinations and the left for quantitative real-time polymerase) were dissected. Results: Compared to the control group, the PCO group showed significantly lower values for the mean body weight, number of preantral and antral follicles, serum levels of estradiol, luteinizing hormone, testosterone, and follicle-stimulating hormone, and gene expression of TGFB1, GDF-9 and BMPR2 (p<0.05). Serum progesterone levels were significantly higher in the PCO animals than in the control group (p<0.05). No significant between-group differences (p>0.05) were found in BMP6 or BMP15 expression. Conclusions: In animals with EV-induced PCO, the preantral follicles did not develop into antral follicles. In this mouse model, the gene expression of TGFB1, GDF9, and BMPR2 was lower in preantral follicles, which is probably related to the pathologic conditions of PCO. Hypoandrogenism was also detected in this EV-induced murine PCO model.
Predictive Modeling in Marketing: Ensemble Methods for Response Modeling
Authors: Alves Werb Gabriela , Schmidberger Martin
Published: August 2021

Ensemble methods have received a great deal of attention in the past years in several disciplines. One reason for their popularity is their ability to model complex relationships in large volumes of data, providing performance improvements compared to traditional methods. In this article, we implement and assess ensemble methods’ performance on a critical predictive modeling problem in marketing: predicting cross-buying behavior. The best performing model, a random forest, manages to identify 73.3 % of the cross-buyers in the holdout data while maintaining an accuracy of 72.5 %. Despite its superior performance, researchers and practitioners frequently mention the difficulty in interpreting a random forest model’s results as a substantial barrier to its implementation. We address this problem by demonstrating the usage of interpretability methods to: (i) outline the most influential variables in the model; (ii) investigate the average size and direction of their marginal effects; (iii) investigate the heterogeneity of their marginal effects; and (iv) understand predictions for individual customers. This approach enables researchers and practitioners to leverage the superior performance of ensemble methods to support data-driven decisions without sacrificing the interpretability of their results.
Robo Advisory Customer Groups: Who Requires Advice?The authors wish to thank Anselm Hüwe, Andreas Pfingsten (the editor), and an anonymous reviewer for their comments, suggestions, and valuable feedback.
Authors: Blaschke Justus , Kriebel Johannes
Published: August 2021

Prior literature has often investigated how robo advisors can broaden their customer base. This study is based on the observation that some customers value the risk elicitation of robo advisors (guidance customers), whereas others value other aspects such as the simplicity and convenience of these services. Based on empirical robo advisory data, we build machine learning models to identify guidance customers. The models make predictions based on the financial knowledge of customers to a large extent. The age of a customer, the amount invested, income, and available assets are further important determinants.

Impacts of Real-Time Transit Information on Bus Passengers’ Travel Choices Based on Travel Behaviour Survey
Authors: Deng Yajuan , Chen Mingli
Published: August 2021

Real-time transit information (RTI) service can provide travellers with information on public transport and guide them to arrange departure time and travel mode accordingly. This paper aims to analyse travellers’ choices under RTI by exploring the relationship between the related variables of RTI and passengers’ travel choice. Based on the stated preference (SP) survey data, the ordinal logistic regression model is established to analyse the changing probability of passengers’ travel behaviour under RTI. The model calculation results show that travellers getting off work are more likely to change their travel choice under RTI. When data from the control and experimental groups are compared, the differences in route selection are significant. Specifically, passengers with RTI have a more complex route selection than those without, including their changes of travel mode, departure time, vehicles, and stop choices. The research findings can provide insights into the optimisation of intelligent transit information systems and the strategy of RTI. Also, the analysis of passengers’ travel choice under RTI in the transit network can help to improve network planning.
Megaregional Passenger Transportation Hub Location Problem Considering Congestion Effects
Authors: Yan Huang , Zhang Xiaoning
Published: August 2021

The need to make effective plans for locating transportation hubs is of increasing importance in the megaregional area, as recent research suggests that the growing intercity travel demand affects the efficiency of a megaregional transportation system. This paper investigates a hierarchical facility location problem in a megaregional passenger transportation network. The aim of the study is to determine the locations of hub facilities at different hierarchical levels and distribute the demands to these facilities with minimum total cost, including investment, transportation, and congestion costs. The problem is formulated as a mixed-integer nonlinear programming model considering the service availability structure and hub congestion effects. A case study is designed to demonstrate the effectiveness of the proposed model in the Wuhan metropolitan area. The results show that the congestion effects can be addressed by reallocating the demand to balance the hub utilisation or constructing new hubs to increase the network capacity. The methods of appropriately locating hubs and distributing traffic flows are proposed to optimise the megaregional passenger transportation networks, which has important implications for decision makers.
Cephalopod species identification using integrated analysis of machine learning and deep learning approaches
Authors: Tan Hui Yuan , Goh Zhi Yun , Loh Kar-Hoe , Then Amy Yee-Hui , Omar Hasmahzaiti , Chang Siow-Wee
Published: August 2021

Background

Despite the high commercial fisheries value and ecological importance as prey item for higher marine predators, very limited taxonomic work has been done on cephalopods in Malaysia. Due to the soft-bodied nature of cephalopods, the identification of cephalopod species based on the beak hard parts can be more reliable and useful than conventional body morphology. Since the traditional method for species classification was time-consuming, this study aimed to develop an automated identification model that can identify cephalopod species based on beak images.

Methods

A total of 174 samples of seven cephalopod species were collected from the west coast of Peninsular Malaysia. Both upper and lower beaks were extracted from the samples and the left lateral views of upper and lower beak images were acquired. Three types of traditional morphometric features were extracted namely grey histogram of oriented gradient (HOG), colour HOG, and morphological shape descriptor (MSD). In addition, deep features were extracted by using three pre-trained convolutional neural networks (CNN) models which are VGG19, InceptionV3, and Resnet50. Eight machine learning approaches were used in the classification step and compared for model performance.

Results

The results showed that the Artificial Neural Network (ANN) model achieved the best testing accuracy of 91.14%, using the deep features extracted from the VGG19 model from lower beak images. The results indicated that the deep features were more accurate than the traditional features in highlighting morphometric differences from the beak images of cephalopod species. In addition, the use of lower beaks of cephalopod species provided better results compared to the upper beaks, suggesting that the lower beaks possess more significant morphological differences between the studied cephalopod species. Future works should include more cephalopod species and sample size to enhance the identification accuracy and comprehensiveness of the developed model.
IdentPMP: identification of moonlighting proteins in plants using sequence-based learning models
Authors: Liu Xinyi , Shen Yueyue , Zhang Youhua , Liu Fei , Ma Zhiyu , Yue Zhenyu , Yue Yi
Published: August 2021

Background

A moonlighting protein refers to a protein that can perform two or more functions. Since the current moonlighting protein prediction tools mainly focus on the proteins in animals and microorganisms, and there are differences in the cells and proteins between animals and plants, these may cause the existing tools to predict plant moonlighting proteins inaccurately. Hence, the availability of a benchmark data set and a prediction tool specific for plant moonlighting protein are necessary.

Methods

This study used some protein feature classes from the data set constructed in house to develop a web-based prediction tool. In the beginning, we built a data set about plant protein and reduced redundant sequences. We then performed feature selection, feature normalization and feature dimensionality reduction on the training data. Next, machine learning methods for preliminary modeling were used to select feature classes that performed best in plant moonlighting protein prediction. This selected feature was incorporated into the final plant protein prediction tool. After that, we compared five machine learning methods and used grid searching to optimize parameters, and the most suitable method was chosen as the final model.

Results

The prediction results indicated that the eXtreme Gradient Boosting (XGBoost) performed best, which was used as the algorithm to construct the prediction tool, called IdentPMP (Identification of Plant Moonlighting Proteins). The results of the independent test set shows that the area under the precision-recall curve (AUPRC) and the area under the receiver operating characteristic curve (AUC) of IdentPMP is 0.43 and 0.68, which are 19.44% (0.43 vs. 0.36) and 13.33% (0.68 vs. 0.60) higher than state-of-the-art non-plant specific methods, respectively. This further demonstrated that a benchmark data set and a plant-specific prediction tool was required for plant moonlighting protein studies. Finally, we implemented the tool into a web version, and users can use it freely through the URL: http://identpmp.aielab.net/.
Establishment of a ferroptosis-related gene signature for prognosis in lung adenocarcinoma patients
Authors: Cai Jingjing , Li Chunyan , Li Hongsheng , Wang Xiaoxiong , Zhou Yongchun
Published: August 2021

Objective

Lung cancer is the most common malignancy worldwide and exhibits both high morbidity and mortality. In recent years, scientists have made substantial breakthroughs in the early diagnosis and treatment of lung adenocarcinoma (LUAD), however, patient prognosis still shows vast individual differences. In this study, bioinformatics methods were used to identify and analyze ferroptosis-related genes to establish an effective signature for predicting prognosis in LUAD patients.

Methods

The gene expression profiles of LUAD patients with complete clinical and follow-up information were downloaded from two public databases, univariate Cox regression and multivariate Cox regression analysis were used to obtain ferroptosis-related genes for constructing the prognos tic risk model, AUC and calibration plot were used to evaluate the predictive accuracy of the FRGS and nomogram.

Results

A total of 74 ferroptosis-related differentially expressed genes (DEGs) were identi fied between LUAD and normal tissues from The Cancer Genome Atlas (TCGA) database. A five-gene panel for prediction of LUAD prognosis was established by multivariate regression and was verified using the GSE68465 cohort from the Gene Expression Omnibus (GEO) database. Patients were divided into two different risk groups according to the median risk score of the five genes. Based on Kaplan-Meier (KM) analysi, the OS rate of the high-risk group was markedly worse than that of the low-risk group. We also found that risk score was an independent prognostic indicator. The receiver operating characteristic ROC curve showed that the proposed model had good prediction ability. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional analyses indicated that risk score was prominently enriched in ferroptosis processes. Moreover, at the score of immune-associated gene sets, significant differences were found between the two risk groups.

Conclusions

This study demonstrated that ferroptosis-related gene signatures can be used as a potential predictor for the prognosis of LUAD, thus providing a novel strategy for individualized treatment in LUAD patients.

Materials and Methods: The Cross-sectional (retrospective) study was conducted on 21 patients, that presented to the study institute with accidental ingestion of Indian sandbur. The data belonged to a period from January 2020 to December 2020. The medical records of the patients were analysed and data were collected using a structured questionnaire. The questionnaire included information such as age, sex, anatomical lodgement of foreign body, signs, and symptoms, duration of lodgement before confirmation and removal. Results: The mean (SD) age of patients was 33.47(17.41) years. Majority of the patients were males (66%). The most common site of impaction was vocal cords of the larynx, seen in seven (33.33%) patients. The most common presenting symptom was foreign body sensation. In all cases, the foreign body was successfully removed either under local (11 cases) or General Anaesthesia (GA) (10 cases). In the postoperative period, persistence of hoarseness of voice was observed in three patients. Conclusion: Bhurut should be suspected in patients presenting with foreign body ingestion, associated with a desert region. Removal of the bhurut under local or GA achieves good results.

COVID-19 is a virus of the species of the Family coronaviridae known as as SARS-COV-2. This virus is easily contracted and/transmitted from an infected person to another healthy individual and has continued to spread rapidly. The aim of this review is to identify laboratory methods used in the diagnosis of COVID-19 infection. COVID-19 test are aimed at detecting active infection, or past infection, or an immunization so as to treat and curb the further spread of the virus. The initial viral detection is typically carried out with the upper respiratory tract (URT) sample. Repeated testing is particularly helpful and essential if a patient has a clinical appearance of viral pneumonia, radiographic results consistent with pneumonia and/or a history of potential exposure. The Centre of Disease Control and Prevention, CDC recommends the collection of specimens from the lower respiratory tract, upper respiratory tract, and the blood. The lower respiratory tract sample includes; the sputum, broncheoalveolar lavage, bronchial wash, tracheal aspirate, and pleural fluid.  The upper respiratory tract specimens include; the nasopharyngeal swab, and oropharyngeal swab (NP/OP swabs). Some laboratory techniques developed and in use for the detection of Covid-19 are; nucleic acid amplification tests (NAATs), antibody detection, and viral antigen detection. The role of the laboratory assay in diagnosis of COVID-19 infection or disease cannot be                            under-estimated, timing and site of specimen collected must be followed by adequate                 professional training to ensure result accuracy. This review provides information on available laboratory techniques for the diagnosis of the viral infection and their potential merits and           limitations.

The purpose of the study was to optimize the sowing date and nitrogen level in early maturing rice (Pusa basmati 1509) under temperate climate for realizing higher yield. The experiment was conducted on silty clay loam soil, neutral in reaction, low in available nitrogen, medium in available phosphorus, potassium and organic carbon. Treatments included three sowing dates viz 20th April, 30th April, and 10thMay and five nitrogen levels viz 0, 30, 60, 90 and 120 kg N ha-1 laid out in split plot design with three replications. Among the sowing dates, 20th April took maximum no. days to reach different phenological stages and maturity. The GDD (1431) and HTU (15161 oC d-1 hr-1) requirement to reach maturity was maximum for 20th of April sowing. Significantly higher grain yield, higher HUE (2.90 kg ha-1 oC-1 d-1) and HTUE (0.273 kg ha-1 oC-1 hr-1) was realized form 1st date of sowing i.e., 20th of April. Higher doses of 120 kg N ha-1resulted in slightly more number of days to reach different phenological stages and maturity that was also reflected in higher accumulation of more GDD 1403° and HTU (14987 °C d-1 hr-1) at maturity.  Highest HUE (1.42 kg ha-1 oC-1 d-1) and HTUE (0.133 kg ha-1 °C-1 hr-1) was realized at 120 kg N ha-1. Further among the sowing dates, 20th April and 30th April had significantly higher growth parameters viz. plant height, leaf area index, tillers m-2, dry matter accumulation, leaf area index and SPAD reading as compared to 10th May. Most of the growth and yield parameters were found significantly higher at nitrogen level of 120 kg ha-1. However, most of them were at par with followed by nitrogen level of 90 kg ha-1.

The surface water resources of Bodo/Bonny communities in Rivers State suffers regular pollution of its ecosystem due to increase in crude oil exploration, refining and activities of other industrial establishments operating within the coastal areas of the Ogoniland of the Niger Delta region of Nigeria.  This have resulted in the wide scale contamination of most of its creeks, swamps and rivers with hydrocarbons and dispersant products resulting in the alteration of the ecological integrity of fragile aquatic systems, bioaccumulation of chemical contaminants by zoobenthos, sediment enrichment, and smothering or asphyxiation of the organisms in water by oil coating, thereby causing death. These conditions have resulted in serious threat to public health and the ecosystems. The study was aimed at determining the physico-chemical characteristics of Bodo/Bonny coastal waters impacted by crude oil spills and their effect on the marine ecosystems. Surface water was collected from 5 stations (BBW1, BBW2, BBW3, BBW4 and LFPW5) with LFPW5 serving as control. Physico-chemical parameters were investigated following standard methods. The results of the physicochemical characteristics of the various sampling points in the dry season showed that pH, TDS and Electrical conductivity values showed statistically significant differences at   P < 0.005. pH was slightly acidic in all sampling locations except for the Link fish pond, the values ranged from 6.20–6.40 which was below DPR Limit of 6.5-8.5 for potable water, TDS recorded 43175–57075 mg/L above DPR permissible Limit of 5000mg/L. Electrical Conductivity (EC) values ranged from 54050 -57050 µS/cm. The Dissolved Oxygen, Biological Oxygen Demand, Turbidity, Chloride recorded in this study varied significantly at P< 0.05. Results of the physicochemical parameters of surface water in the wet season fell within the standard limits except for the conductivity that was above the permissible limits. Comparatively the mean pH value of surface river water with Linked fish pond water which served as the control revealed that the Link fish pond water had the highest pH value of 7.9 than the surface river water samples with a pH of 6.4, TDS (60,200 mg/L), Electrical Conductivity (EC) (µS/cm3) followed a similar pattern with the mean EC value of 55,800 mg/L as against 750mg/L for the Link Fish pond water. Temperature recorded 310C as against 300C for the link fish pond while the Salinity (mg/L) of the surface river water was 31.63 mg/L. Dissolved Oxygen was  2.3 mg/L, Biochemical Oxygen Demand values for the surface river water was 0.49 mg/L while the Link fish pond water had 0.3mg/L. These values obtained in this study shows that the spilled oil in the water could impact on species abundance and biomass by depleting and depriving the fishes from available O2 for survival thus resulting in asphyxiation.
