Não verás ciência alguma: educação na ditadura militar brasileira
Authors: Rodriguez Adalberto Diehl
Published: August 2019

A partir da denúncia literária contida em um trecho do romance Não Verás País Nenhum, de Ignácio de Loyola Brandão, o artigo, como objetivos, aponta as estratégias da ditadura militar brasileira para negar a ciência como objeto possível da Educação e identifica os efeitos na formação e desenvolvimento da ciência no contexto dos anos de chumbo. Os objetivos são cumpridos a partir da pesquisa bibliográfica como metodologia. O trabalho argumenta que o silêncio e a desconstrução quanto às possibilidades de uma formação discursiva da ciência foram estratégias adotadas pelo Regime Militar para negar a ciência como objeto educacional; que dessas estratégias resultaram o esvaziamento do nicho profissional do cientista, o fechamento de institutos, a criação de organismos prioritariamente técnicos, o fomento ao Brasilianismo face ao declínio das atividades da intelligentsia nacional. O artigo conclui que o regime ditatorial institucionalizou uma pedagogia na qual o ser humano é apropriado como capital em um processo de ensino tecnicista restrito às habilidades para um mercado de trabalho recrutador de profissionais básicos num saber fazer. Palavras-chave: Educação. Ciência. Ditadura Militar. Universidade brasileira. YOU WILL NOT SEE ANY SCIENCE: EDUCATION IN BRAZILIAN MILITARY DICTATORSHIP   Abstract: From the literary denunciation in an excerpt from the novel Não Verás País Nenhum, by Ignacio de Loyola Brandão, this article points out as  main goals the strategies of the Brazilian military dictatorship to deny science as a possible object of education, and identifies the effects that result in destitution of science in the educational context of the anos de chumbo. The objectives are met through the bibliographical research as a methodology. The paper argues that the silence and the deconstruction of the possibilities of a discursive formation of science were strategies adopted by the military regime to deny science as educational purpose; that these strategies resulted diminishing the professional niche scientist, closing institutes, the creation of primarily technical bodies, fostering Brasilianism to face the decline of the activities of the national intelligentsia. The article concludes that the dictatorial regime institutionalized a pedagogy in which human capital is suitable as a process restricted to the technicalities teaching skills to a labor market in a professional recruiter basic know-how.

A contemporaneidade da crise da educação no pensamento de Hannah Arendt
Authors: Belinaso Guimarães Rodrigo
Published: August 2019

Resumo: A escola pública é o local principal dos questionamentos deste artigo. Nele, a sala de aula é vista como um espaço de aprendizagem significativo e onde ainda podem ocorrer encontros fundamentais para a constituição do mundo na perspectiva de Hannah Arendt (2002). Atualmente, os sintomas da crise na educação fazem com que a sala de aula se converta num espaço de angústias e frustrações, assim, jovens e professores podem ter uma relação muitas vezes marcada pelo desinteresse, pelo isolamento, pela opressão, pela violência, que impede qualquer abertura para o vir a ser. Assim, pergunto-me sobre a forma como posso dotar de sentido minha prática de professor e pesquisador, diferenciando-me dos papéis que não quero assumir. Em outras palavras, questiono neste artigo sobre a possibilidade de abdicar de pronunciar aos jovens como deve ser o vir a ser do mundo em que habitam. Para isso, parto de um sentimento de crise, vivenciado nas dificuldades de aprendizagem e nos encontros interditos em sala de aula, que me convidam a um repensar constante sobre minha prática educativa. Dessa forma, procuro sintetizar alguns conceitos fundamentais de Hannah Arendt sobre a crise da educação, percorrendo seu pensamento para, por fim, relacioná-los com a contemporaneidade das minhas vivências. Palavras-chave: Educação. Estudos Culturais. Ensino Médio. Crise na Educação.

In it, the classroom is seen as a significant learning space and where can still occur important meetings for the foundation of the world in the Hannah Arendt’s perspective (2002). Nowadays, the symptoms of the crisis in education makes the classroom becomes an area of anguish and frustration, thus, youth and teachers can have a relationship often marked by indifference, isolation, oppression, violence, obstructing any opening to become to be. So, I wonder about how I can give direction to my practice teacher and researcher, differentiating me from the papers that do not want to take. In other words, I question in this article about the possibility of giving up to pronounce for the young people how must to be the world they to live. For this, I start of a sense of crisis; it has lived in the difficulties of learning and banned gatherings in the classroom, which invites me to a constant rethinking about my educational practice. In this way, I try to summarize some Hannah Arendt’s concepts about the education crisis, covering their thinking to finally compare them to the contemporary nature of my experiences.

Published: August 2019

Resumo: Este artigo analisa a forma e os desafios de inserção das Tecnologias de Informação e Comunicação (TIC) na formação inicial de professores de Física. O objetivo geral é investigar os cursos de formação de professores, em nível de graduação, quanto aos conhecimentos referentes às TIC em sua base curricular, assim como compreender quais são os desafios desses cursos para proporcionar tal formação com qualidade. Partimos da hipótese de que os cursos de formação de professores de Física estão proporcionando poucos momentos que possibilitam problematizar as TIC durante a formação do educador, o qual não estaria percebendo a importância desses recursos e dos conhecimentos inerentes a eles, bem como a contribuição que possibilitam à prática educativa. Desse modo, essa investigação está focada na formação do futuro professor de Física da Educação Básica para o uso das TIC. Para isso, focalizamos a investigação nos cursos de licenciatura em Física de cinco universidades federais do RS, analisando os projetos pedagógicos desses cursos e realizando entrevistas com professores formadores dessas instituições. Esta pesquisa confirmou a necessidade de pensarmos em uma estrutura formativa menos fragmentada, em que as TIC – e não só elas – sejam discutidas em diferentes contextos e ambientes, de forma a permear todo o curso de formação. Palavras-Chave: Formação de Professores. Ensino de Física. Tecnologias de Informação e Comunicação. PEDAGOGICAL AND TECHNOLOGICAL INNOVATION IN TEACHERS’ INITIAL FORMATION Abstract: This article looks at the way and the challenges of integration of Information and Communication Technologies (ICT) in Physics teachers initial training. The overall objective is to investigate teacher training courses at the undergraduate level, as the knowledge related to ICT in their curriculum base, as well as understand what are the challenges for these courses provide such training quality. Our hypothesis is that the Physics teacher initial training courses are providing few moments that make it possible to question the ICT during the formation of the educator, which would not realize the importance of these resources and inherent knowledge as well as the contribution that enable the educational practice. Thus, this research is focused on the training of future Physics teachers in Basic Education in order to use ICT. Then, we focus on research in undergraduate Physics courses in five Federal Universities of the state of Rio Grande do Sul, in order to analyze the educational projects of these courses and to conduct interviews with teachers trainers of these institutions. This research confirmed the need to think of a less fragmented structure training in ICT - and not only them – will be discussed in different contexts and environments in order to permeate the whole training course.

Como questionamos a ditadura nas aulas de Geografia
Authors: Batista Bruno Nunes
Published: August 2019

Resumo: Este texto compartilha experiências pedagógicas desenvolvidas em turmas de Ensino Médio, nas aulas de Geografia, a partir da temática relacionada à ditadura midiática-civil-militar no Brasil. Fazendo alusão aos cinquenta anos do golpe militar, em 1964, elaborou-se um conjunto de sequências didáticas associando a globalização ao período dos “anos de chumbo”. Nossa construção didática esteve amparada na sociologia crítica da mídia de Edgar Morin, Juremir Machado da Silva e Pedrinho Guareschi. Desse modo, as atividades privilegiaram a interpretação da influência da grande mídia no apoio ao golpe e na estabilidade política da ditadura. Foram empregados recursos didáticos diversificados, como a análise de reportagens históricas, a compreensão de programas audiovisuais da época e o trabalho com imagens. Durante as aulas, destacamos a inseparabilidade entre os conceitos de espaço e tempo no ensino de Geografia. Com efeito, ao compreenderem a contemporaneidade sociopolítica brasileira como corolário de uma historicidade, os sujeitos envolvidos nos processos de ensino e aprendizagem podem operar qualitativamente na sociedade da informação, instituindo um olhar crítico sobre os meios de comunicação; logo, formando uma teia própria de conhecimento. Palavras-chave: Ensino de Geografia. Ditadura na escola. Crítica da mídia. Aprendizagem.  HOW CAN WE QUESTION DICTATORSHIP IN GEOGRAPHY CLASSES Abstract: This paper aims at sharing pedagogical practices developed in high school Geography classes. Their main subject was media-civil-military dictatorship in Brazil. The fiftieth anniversary of 1964 Brazilian military coup d’état motivated the production of a set of educational activities which associate globalization with the so called “anos de chumbo” (plumb years). Our theoretical framework relies on the works of media critical sociology of Edgar Morin, Juremir Machado da Silva and Pedrinho Guareschi. Thereby, the activities focused on interpretation of great media and communication's role on supporting the coup d’état and dictatorship maintenance. Diverse educational resources were employed, varying from historical materials analysis, image observation and audiovisual programs discussion from that political period. In class, we tried to stress the necessity of connecting geographical concepts of time and space. From that, we would argue that students who understand Brazilian social-political contemporary elements as a historical process are able to look critically at the information society media; therefore spinning their own knowledge web.

Authors: Al-Wakeel Ahmed , Zahran Eman , Hafez Elsayed , Hamed Mohamed , Zaki Viola
Published: August 2019

Objective: This study was undertaken to evaluate the potential role of Mannan oligosaccharides (MOS) on growth performance, liver and intestine tissue morphology, and gut microbiota of Nile tilapia (Oreochromis niloticus).
Design: Controlled study.
Animals: Three groups of Nile tilapia.
Procedures: Three diets were formulated to contain 0 % of MOS 500 (MOS) as control (control), 0.05% of MOS plus adding MOS into water as well at level of 12.5 mg/l (MOS (feed +water), and the third group MOS was added only to water (MOS water) at the same level, and fed to Nile tilapia for 6 weeks.
Results: Simultaneous water and feed additives with (MOS feed+water) at (0.05% of feed + 12.5 mg/l water) caused a significant increase in growth parameters (initial and final weight, weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and condition factor (k), when compared to both MOS added only in tank water (MOS water) and control groups. In addition, MOS in both treatment types increased survival rates significantly compared to the control. Polymerase chain reaction and denaturing gradient gel electrophoresis (PCR-DGGE) analysis showed that a single species or species that contained chemically equivalent DNA dominated the intestinal tract of all Nile tilapia regardless of dietary treatment. While MOS had no adverse effect of intestinal histology, an increase in the villi length was recorded.
Conclusion and clinical relevance: Collectively, our results indicate that MOS added to feed and water could be used to enhance the growth performances, increase the survivability and exert beneficial effects on the gut microbiota of Nile tilapia.

A Pareto Optimal Solution for Environmental/Economic Power Dispatch
using Multi-objective Genetic Algorithm
Authors: Talaq Jawad
Published: August 2019

The aim of this paper is to apply genetic algorithm (GA) to the solution of the environmental economic power dispatch problem. The environmental economic power dispatch is a multi-objective optimization problem. Fuel cost is considered as one of the objectives. The other objective is emissions such as SO2 or NOx or a combination of both. A trade-off relation between fuel cost and emissions can be formed through a pareto optimal front. Valve point opening and prohibited operating zones add non-smoothness and non-convexities to the objective functions. Evolutionary algorithms can efficiently solve such non-smooth and non-convex problems. Solutions need to be diversified and distributed among the whole range of the pareto optimal front. This allows operators to trade-off between fuel cost and emissions in feasible optimal regions. Applying genetic algorithm with diversity enhancement proves its effectiveness. Application of the algorithm on three and six unit systems is demonstrated

Authors: Chukwu M. N. , Kadafur S. J.
Published: August 2019

The study examines the strength of environmental education in Lekki-Lagos and its impact on community and grass-root development by considering a targeted sample population comprising some respondents that are living or working in Lekki community in Lagos. A qualitative survey was conducted using participatory observation, interviews, and a structured questionnaire. The questionnaire was validated through peer review and pilot testing. Data collected were summarized and computed using descriptive statistics while a paired t-test and Turkey’s HSD test were used for further analysis. Results showed that 92% of the respondents affirmed that environmental education impacted positively on the community attracting the government, non-governmental and private organizations to help in developing the area through construction of roads, pedestrian bridges, drainages and sea embankments thus reducing flooding, man hour loss due to traffic jam and rate of pollution. There was also a decrease in loss of lives and properties. Investors were attracted to Lekki, reducing poverty and social imbalance thus increasing community development. There is a significant difference between the state of Lekki now and before the intervention of public-private practice in developing the area (P< 0.05). It is recommended that the government and other stakeholders should collaborate on a higher scale to enhance developing the unreached communities.
Evaluating Competition Constraint on Land Accessibility by Urban Crop Farmers in Lagos
Authors: Odudu C. O.
Published: August 2019

The study evaluated the constraint of competition on urban crop farming in Lagos with a view to identifying issues that must be resolved to facilitate practitioners’ land accessibility in the metropolis. Crop farmers in seven out of ten communities where urban crop farming was found to be thriving within the metropolis were selected through multi-stage sampling which involved both purposive and simple random samplings and were administered with structured questionnaires. All the farming communities were delineated by the Lagos State Agricultural Development Authority (LSADA). Data collected were analysed using descriptive statistics while linear regression analysis was used to test the formulated research hypothesis. The study showed that farmers were forced out (19.5%) of their locations, 10.3% vacated voluntarily, 1.4% left due to high rents, 2.9% unidentified and 67.8% were missing values. Urban farmers in the study area were, however, found not to be affected by competition and high rents as they were occupying marginal lands that did not attract other competing uses. The regression analysis showed that competition constraint accounted for 3.5% of farmers’ productivity establishing that competition with other uses significantly affected urban farmers’ productivity as they were consigned to marginal lands. The study therefore concluded that government should support/promote the activity by providing agricultural lands in designated areas of the metropolis for urban farming.

Authors: Isagba E. S. , Kadiri S. , Ilaboya I. R.
Published: August 2019

This paper investigated the use of yam peel as a natural adsorbent for the removal of Copper (Cu) and Manganese (Mn) from waste water. The yam peels were thoroughly washed with distilled water, dried, pulverized and carbonized. The carbonized yam peel was then characterized for its particle sizes, moisture content, ash content, volatile matter, Methylene Blue number, Iodine number. The raw yam peels were prepared using the same procedure, but was not carbonized. The adsorption of Mn(II) and Cu(II) ions were investigated using adsorption experiment at room temperature. The effect of contact time, metal ion concentration and dosage were evaluated. The residual concentrations of the metal ions were determined by Atomic Absorption Spectrophotometer (AAS). Experimental data obtained were analyzed using Kinetic models and Isotherms such as Pseudo- First order kinetic models, Pseudo-second order kinetic models, Langmuir isotherms and Freundlich isotherm. The analysis showed that the pseudo-second order kinetic model best described the adsorption of the metal ions; ( Cu; r2 = 0.991 for RYP and r2 = 0.834 for AYP) and (Mn; r2 = 0.958 for RYP and r2 = 0.896 for AYP) and the experimental data best fit the Freundlich model; (Cu; r2 = 0.564 for RYP and r2 = 0.871 for AYP) and (Mn; r2 = 0.685 for RYP and r2 = 0.736 for AYP). Finally, optimum removal efficiencies of 30.54% for Mn(II) and 39.62% for Cu(II) were obtained for AYP at concentrations of 50mg/l and mass dosage of 1.0g, 120 minutes contact time and a pH of 6.8.

Authors: Olayinka D. N. , Irivbogbe H. E.
Published: August 2019

This study discusses the assessment and analysis of areas vulnerable to flooding in Eti-Osa and Lagos Island Local Government areas of Lagos state, using Geographic Information System (GIS), LIDAR and spatial modelling techniques. These areas require quality assessment of their level of vulnerability to floods, in order to take adequate measures and develop programs that will help prevent the impacts of flooding. A set of indicators influencing flooding, which are elevation, slope, flow accumulation and land use, were identified and used in the study. A vulnerability scale of (1 – 3) was developed, where 1 represents ‘low’, 2 represents ‘moderate’ and 3 represents ‘high’. The indicators identified were reclassified in the vulnerability scale. The flood vulnerability maps, in three different case scenarios, were created using the weighted overlay of the reclassified indicators identified. The weights used are determined by a Pairwise comparison method (Analytical Hierarchical Approach (AHP). The mapping method was implemented in ArcGIS environment. The vulnerability mapping results show that for a normal case scenario, 27.15% of the area have high vulnerability, 49.79% have moderate vulnerability and 23.06% have low vulnerability. However, for a worst-case scenario, 60.01% have high vulnerability, 37.71% have moderate vulnerability and 2.28% have low vulnerability. Buildings at risk and the extent of areas at risk were determined and relevant recommendations were made.

Authors: Edokpia R. O. , Oladeinde M. H.
Published: August 2019

The focus of this study is the use of the Cobb-Douglas’ production function to evaluate the productivity of a manufacturing firm. In order to achieve our aim, secondary data of the production line of the firm, were used. These data include the production output data and cost data, which covered a period from 1991to 2010. A production frontier was established for every manufacturing year using the production function. Business cycle was also used to analyze the deviation between the actual production and the production frontier. The results indicated that for 80 percent of the years under study, the firm operated above the production frontier, and therefore considered technically efficient for those years, with the exception of the years 1994, 2005, 2007 and 2008 where the firm operated below the production frontier. Also the deviation between the actual production and the production frontier followed the business cycle. The trend of actual production curve showed that there is a tendency of low productivity in the future.

Authors: Epuh E. E. , Ufot A. I. , Orji M. J.
Published: August 2019

Over the years, the oil and gas industries have been engaging in traditional practices and procedures in their mode of operation in pipeline management. This has brought some draw backs in terms of planning and mapping of pipeline facilities. Several challenges in terms of natural disaster, equipment failure, and human error could not be averted because the traditional methods could not produce survey maps and plans required for “real time “applications. The advent of Geographic Information System (GIS) technology in the oil and gas industries has brought about rapid changes and improvements in the activities of the oil and gas industries in terms of exploration, production and transmission of products from the field to the end users. In this research, digital maps showing oil and gas pipelines as well as other relevant features such as terrain, vegetation and settlements within the study area were generated. A relational database model was developed using pipeline attributes such as; the pipeline diameter, date of installation, pressure, coating and soil type. Queries on the database provided the required information such as; the required date of maintenance of pipes, areas prone to sabotage, areas with specific pipe diameters in various sections, previous spillages and the affected areas.

Authors: Ogirigbo O. R. , Inerhunwa I.
Published: August 2019

In this study, two slags of different chemical compositions were blended with a CEM I 52.5R-type Portland cement at 30% wt. replacement ratio. Various tests such as strength, water and chloride ion permeability test were carried out at a high temperature of 38°C. The performances of the slag blends were measured against that of a CEM I 42.5R-type Portland cement. The results obtained showed that the performances of the slag blends were better than that of the CEM I 42.5R cement. In comparing the performances of the slags, the blend prepared from slag 1 had higher strengths and better transport properties than that prepared from slag 2, and this was attributed to the higher basicity and alumina content of slag 1. The findings of the study suggest that in tropical/ high temperature environments, the chemical composition of the slags play an important role in determining their performance.
Maintenance Practice and Occupant’s Satisfaction in Public Housing Estates: An Osobgo, Nigeria Perspective
Authors: Ige V. O. , Binuyo O. P. , Jimoh D. A.
Published: August 2019

The paper appraises the maintenance practice and residents’ satisfaction of public housing estates in Osogbo, Nigeria with a view to encouraging best practices and adequate maintenance strategies in a proposition to preserving the existing housing stock and enhanced maintenance of public estates in the study area. One Hundred and Five (105) questionnaires were distributed among the residents of two (2) residential estates and 97 questionnaires were retrieved, representing 92.40%. Opinion of the Estate Surveyors and Valuers was also sought on the factors affecting maintenance in public housing estate. Analysis was carried out through the use of mean, severity index, cross-tabulation and Chi-Square test of association. It was discovered that there is no statistically significant relationship between maintenance practice and public services alongside infrastructures in the estates. Although, there is a significant relationship between occupants’ level of satisfaction with maintenance of public services and infrastructures; the Phi and Cramer's V tests revealed a very weak strength in the association. The paper therefore suggests an integrated maintenance approach for effective upkeep of public estates infrastructures and facilities.
Comparison between Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and Landsat 8 Operational Land Imager (OLI) Assessment of Vegetation Indices
Authors: Makinde E. O. , Obigha A. D.
Published: August 2019

The Landsat system has contributed significantly to the understanding of the Earth observation for over forty years. Since May 2013, data from Landsat 8 has been available online for download, with substantial differences from its predecessors, having an extended number of spectral bands and narrower bandwidths. The objectives of this research were majorly to carry out a cross comparison analysis between vegetation indices derived from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and Landsat 8 Operational Land Imager (OLI) and also performed statistical analysis on the results derived from the vegetation indices. Also, this research carried out a change detection on four land cover classes present within the study area, as well as projected the land cover for year 2030. The methods applied in this research include, carrying out image classification on the Landsat imageries acquired between 1984 – 2016 to ascertain the changes in the land cover types, calculated the mean values of differenced vegetation indices derived from the four land covers between Landsat 7 ETM+ and Landsat 8 OLI. Statistical analysis involving regression and correlation analysis were also carried out on the vegetation indices derived between the two sensors, as well as scatter plot diagrams with linear regression equation and coefficients of determination (R2). The results showed no noticeable differences between Landsat 7 and Landsat 8 sensors, which demonstrates high similarities. This was observed because Global Environmental Monitoring Index (GEMI), Improved Modified Triangular Vegetation Index 2 (MTVI2), Normalized Burn Ratio (NBR), Normalized Difference Vegetation Index (NDVI), Modified Normalized Difference Water Index (MNDWI), Leaf Area Index (LAI) and Land Surface Water Index (LSWI) had smaller standard deviations. However, Renormalized Difference Vegetation Index (RDVI), Anthocyanin Reflectance Index 1 (ARI1) and Anthocyanin Reflectance Index 2 (ARI2) performed relatively poorly because their standard deviations were high. the correlation analysis of the vegetation indices that both sensors had a very high linear correlation coefficient with R2 greater than 0.99. It was concluded from this research that Landsat 7 ETM+ and Landsat 8 OLI can be used as complimentary data.

Several computer based hydrological models have been developed and used in simulating runoff in various watersheds in different parts of the world and in water resource studies. This study focuses on the combination of Geographic Information System (GIS) with Hydrologic Engineering Center –Hydrologic Modelling System (HEC-HMS) hydrological model to simulate runoff process of the adjoining areas of the Lagos Island and Eti-Osa Local Government Areas (LGAs). The study makes use of LIDAR Digital Elevation Model (DEM), drainage data and land use map for catchment delineation and hydrological modelling, using HECGeoHMS and ArcGIS 10.2. In HEC-HMS 4.2.1, the delineated catchment with all hydrological parameters and average daily rainfall data, are used to simulate and compute rainfall runoff volume, peak discharges for 10 months (between Jan to October) and a total of three years (2012, 2015 and 2017) were considered. Direct runoff volume and depth estimation for the years under review were determined. Results show that the peak discharge occurred on the 2nd of July 2012 at a rate of 14m3/s with an estimated runoff volume at the basin outlet of 39,669.70 x 103m3 (this date tallies with the severe flood events that occurred in that year). The study shows that estimating hydrological outputs is possible with the use of HEC-HMS and GIS. It recommends the application of such technologies in the prediction and development of basic flood warning systems for the area.

This paper presents the findings of the existing university infrastructural facilities (i.e. water supply, electricity supply, office facilities, faculty buildings, laboratory facilities and toilet/convenience facilities) in a representative sample of staff satisfaction with workplace facilities in the School of Environmental Technology, Federal University of Technology, Akure Nigeria. Published literatures have been analysed to review knowledge areas pertaining to workplace facilities and their contributions to organisational high productivity. Various workplace facilities evaluated in this study have been analysed to identify major areas of challenges for the faculty staffs’ satisfaction. A user satisfaction survey was developed to obtain the staffs’ qualitative feedback on their experience and satisfaction with the facilities provided in the faculty. The findings of the survey were analysed and reported to describe the level of satisfaction with the identified performance requirements for the workplace facilities. The main purpose of conducting the study was to determine whether or not the facilities provided at the workplace by the organisation provides the needed satisfaction to the working staff for optimum performance. This paper is of practical value to employers of labour whether private or public sectors, educational institutions, staff and students whose performance of duties are tied to the available facilities. University administrators involved in the provision of infrastructural facilities in the workplace should ensure that the provision and up-keep of the workplace enhancement requirements presented in this paper are properly addressed in the system.
Determination of Conversion Constant between Lagos Datum and Niger Delta Mean Lower Low Water Datum and their Horizontal and Vertical Accuracy Standards using GNSS Observations

With the use of Global Navigation Satellite System (GNSS) technology, it is now possible to determine the position of points in 3D coordinates systems. Lagos datum is the most common Mean Sea Level used in most parts of Nigeria. In Niger Delta, for instance Warri and its environs, the most commonly used datum for height determination is the Mean Lower Low Water Datum. It then becomes necessary to determine a constant factor for conversion between the two datum when the need arises as both are often encountered during Geomatics Engineering field operations. In this paper, the constant to be applied in converting between both datum was determined. The constant was found to be 17.79m. The horizontal and vertical accuracy standard was also determined as well as the stack maps.

The study examined the dynamic nature of water balance parameters over Kano town, a semi-arid environment and impact of Linacre derived potential evapotranspiration method on the supplementary irrigation water needs of selected crops. Monthly Rainfall and Temperature data were collected from the Nigerian Meteorological Agency, Lagos for the period 1953-2012. The study observed that there is a steady decline in annual precipitation over Kano from the first decade (1953-1962) to the fifth decade (1993-2002), after which there was a sign of weak recovery in the last decade (2003-2012). For water loss through potential evapotranspiration, there was a steady rise from the first decade (1953-1962) to the fifth decade (1993-2002), and then followed by a sudden decline in the last decade (2003-2012). The total average of water storage on the other hand, first experienced a rise between the first two decades (1953-1962) and (1963-1972), followed by a steady decline, up until the fifth decade (1993-2002) and finally a rise in the last decade (20032012). The total average of soil water deficit experienced a steady rise between the first and the fifth decades (1953-1962) to (1993-2002), this was followed by a decline in the last decade (20032012). Finally, the total average of water surplus experienced a steady decline between the first and the fifth decades. The observed decline in precipitation, storage, and water surplus, and the rise in water loss from potential evapotranspiration and soil water deficit, suggests that there have been changes in the climatic pattern over Kano and this could be seen in the supplementary irrigation water needs of Tomato/Cabbage/Carrot.

The study assessed heavy metals in the soil and subsequent accumulation in plants at an industrial site at Enyimba city, Abia State, Nigeria. Soil and medicinal plant samples were analyzed for zinc (Zn), lead (Pb) and cadmium (Cd). The highest concentration of Zn (142.06 ± 2.91 mg/kg), Pb (18.06 ± 1.30 mg/kg) and Cd (27.055 ± 2.468 mg/kg) were obtained at the sampling points of 2, 7 and 5, respectively. The highest concentrations of Zn (27.09 ± 1.44 mg/kg) and Cd (2.000 ± 0.156 mg/kg) were accumulated by Azadiractha indica while the highest concentration of Pb (4.58 ± 0.51 mg/kg) was accumulated by Mangifera indica. The levels of Zn and Cd in soil were 13.77 ± 1.35 to 142.06 ± 2.91 and 0.695 ± 0.106 to 27.055 ± 2.468, and their concentrations in Azadiractha indica were 5.06 ± 0.35 to 27.09 ± 1.44 and 0.002 ± 0.001 to 2.000 ± 0.156 mg/kg, respectively. The concentrations of Zn and Cd in soil and Cd in Azadiractha indica reflected a state of pollution relative to Dutch criteria for soil and the FAO/WHO Codex Alimentarius Commission for soil and herbal plants.
Reflexivity and the Codification of Legal Ethics. Remarks on the Basis of Paul Ricoeur’s “Little Ethics” Theory
Authors: Pieniążek Marcin
Published: August 2019

Codes of legal ethics encounter constant waves of criticism. It is pointed out that their disadvantage is, on the one hand, the excessive casuistry, limiting the possibility of taking independent decisions in cases of ethical and professional conflicts, and, on the other hand, the exaggerated declarative character of perfectionist ethical and professional virtues. The gap between the abovementioned perspectives, easily perceived in such codes, results in a dysfunctionality of professional ethics in the actions undertaken by members of the legal profession. The article, apart from the critical-comparative part, includes a proposal of reading and interpreting the content of the codes in a way that transgresses the above opposition. The theoretical basis of the presented position is provided by the concept of “little ethics” formulated by Paul Ricoeur in his work Oneself as Another. The ethical theory developed by Ricoeur combines the elements of Aristotelian ethics of virtues with Kantian ethics of duty. For this reason, it sets a uniform perspective for opposing elements, namely: subordination to the norm of the code and pursuit of ethical and professional self-improvement by legal professionals. The proposed solution belongs to the “reflexive” paradigm of the lawyer’s professional ethics proposed on the basis of Ricoeur’s onto-ethical theory.
