Abstract
Currently, soil erosion is the major environmental problem in the Blue Nile, Hangar watershed in particular. This study aimed to estimate the spatially distributed mean annual soil erosion and map the most vulnerable areas in Hangar watershed using the revised universal soil loss equation. In this model, rainfall erosivity (R-factor), soil erodibility (K-factor), slope steepness and slope length (LS-factor), vegetative cover (C-factor), and conservation practice (P-factor) were considered as the influencing factors. Maps of these factors were generated and integrated in ArcGIS and then the annual average soil erosion rate was determined. The result of the analysis showed that the amount of soil loss from the study area ranges from 1 to 500 tha−1 yr−1 with an average annual soil loss rate of 32 tha−1 yr−1. Considering contour ploughing with terracing as a fully developed watershed management, the resulting soil loss rate was reduced from 32 to 19.2 tha−1 yr−1. Hence, applying contour ploughing with terracing effectively reduces the vulnerability of the watershed by 40%. Based on the spatial vulnerability of the watershed, most critical soil erosion areas were situated in the steepest part of the watershed. The result of the study finding is helpful for stakeholders to take appropriate mitigation measures.
Modification of the Thomas model for predicting unsymmetrical breakthrough curves using an adaptive neural-based fuzzy inference system

Published: January 2019

Abstract
The Thomas equation is a popular model that has been widely used to predict breakthrough curves (BTCs) when describing the dynamic adsorption of different pollutants in a fixed-bed column system. However, BTCs commonly exhibit unsymmetrical patterns that cannot be predicted using empirical equations such as the Thomas model. Fortunately, adaptive neural-based fuzzy inference systems (ANFISs) can be used to model complex patterns found in adsorption processes in a fixed-bed column system. Consequently, a new hybrid model merging Thomas and an ANFIS was introduced to estimate the performance of BTCs, which were obtained for Cd(II) ion adsorption on ostrich bone ash-supported nanoscale zero-valent iron (nZVI). The results obtained showed that the fair performance of the Thomas model (NRMSE = 27.6% and Ef = 64.6%) improved to excellent (NRMSE = 3.8% and Ef = 93.8%) due to the unique strength of ANFISs in nonlinear modeling. The sensitivity analysis indicated that the initial solution pH was a more significant input variable influencing the hybrid model than the other operational factors. This approach proves the potential of this hybrid method to predict BTCs for the dynamic adsorption of Cd(II) ions by ostrich bone ash-supported nZVI particles.

Published: January 2019

AbstractIn this study, a low cost carbon adsorbent was prepared from date seeds. Their surface was modified with potassium hydroxide for use as an adsorbent for the removal of synthetic dye (methyl orange (MO)) from aqueous solutions. The effects of initial MO concentration, adsorbent dosage and temperature were studied. A two-cubed (23) factorial design was carried out on the experimental data, with two replications for the process optimization. The results showed that all three factors and their interactions up to the third order were significant for the removal efficiency of MO. Maximum equilibrium adsorption capacity was 66.26 mg/g at 318 K.

Published: January 2019

AbstractThe UV spectroscopic properties of the principal inorganic ionic species in natural waters were investigated at 25 °C in the wavelength range 195 to 280 nm. All absorbing species were identified and the corresponding molar absorptivities were determined experimentally. No cations were found to influence the UV spectrum. Relatively high molar absorptivities were observed for iodide, bromide and nitrate. The UV spectra of natural waters were calculated using the molar absorptivities and compared with observed signals from synthetic samples. This enabled the dominant components to be determined. Both bromide and nitrate have significant influence on the UV spectrum of natural waters. The study results can be used to predict the UV spectra of ionic solutions and thus evaluate the suitability of UV spectroscopy for given measurement projects.

Abstract
With less than 5% sewerage coverage and abysmal greywater management, Ghana's environment could be highly polluted, especially water resources. The few sewered communities may be guilty of pollution from greywater discharge into stormwater drains. In this study, Asafo, Ghana, was used as a case study to assess greywater characteristics in the major drains in a sewered community. The approach involved desk study reviews and laboratory analysis of greywater samples. The findings showed some inhabitants discharge greywater into neighbourhood drains instead of sewers. Most greywater sources from reviews and sampled drains failed the discharge limits for major contaminants including turbidity (39.4–2,880 NTU), BOD5 (64–700 mg/L), COD (207–2,308 mg/L), TSS (70–4,720 mg/L), TDS (420–2,860 mg/L), nutrients – TKN, NH3-N, NO3−-N, NO2−-N (0–218.5 mg/L), total P and PO43−(1.24–26.18 mg/L), elemental species – Na, K, Mg, etc (0–1.6 mg/L), and microbiological – total and faecal coliforms, and E. coli (2.95–10.4 log CFU/100 ml). High strength greywater accounted for odour emissions where flows stagnated. Greywater characteristics are highly variable but have potential for biological treatment as the BOD5:COD ratios ≥0.5. Ghanaian greywater, including flows from a sewered community, is untreated and polluted, and our environment is unsafe.
Sistema tributário brasileiro: análise da percepção dos operadores do direito tributário à luz dos conceitos de eficiência e justiça fiscal
Authors: Felicio Raphael Maleque , Martinez Antônio Lopo 
Published: January 2019

Objetivo: Analisar a percepção dos operadores do direito tributário quanto à eficiência, à equidade e à complexidade do sistema tributário brasileiro, bem como verificar se na opinião dos mesmos os tributos brasileiros causam mudanças de comportamento do contribuinte, incentivam a prática de planejamento tributário tendente a diminuir o débito tributário ou se geram desigualdade.
Metodologia: A pesquisa adotou uma abordagem quantitativa, utilizando-se de um plano de pesquisa descritivo, mediante aplicação de questionário auto administrado, de perguntas fechadas, a operadores do direito tributário brasileiro.
Resultados: Os resultados mostram que a percepção dos respondentes é de que o sistema tributário brasileiro é considerado regressivo, com forte incidência sobre o consumo, onerando os mais pobres e a classe trabalhadora; ineficiente, já que a percepção foi de que o Fisco tem se preocupado apenas com o combate à corrupção, à medida que a legislação incentiva o planejamento tributário; e complexo, tendo como principais causas a deficiência na redação da legislação e a sua contínua modificação. No geral, é unânime entre os respondentes que há uma necessidade de uma reforma global no sistema tributário nacional.
Contribuições do Estudo: Conhecer a percepção dos operadores do direito tributário brasileiro pode contribuir para a identificação de eventuais questões tributárias para além do texto escrito, que demandariam melhorias quanto aos seus efeitos e aplicabilidade, que podem ser promovidas na legislação, de modo a tornar o sistema cada vez menos complexo, mais eficiente e justo para a sociedade brasileira.

Published: January 2019

Objetivo: O estudo objetivou identificar se existe diferença estatística na percepção dos alunos de diferentes cursos de graduação de uma instituição federal de ensino superior sobre o processo de ensino-aprendizagem das disciplinas na área de contabilidade de custos.
Metodologia: Aplicou-se um instrumento elaborado por Paswan e Young (2002) que analisaram características acadêmicas que influenciam a percepção dos discentes, por meio dos construtos: envolvimento do professor; envolvimento do estudante; interação estudante-professor; demandas do curso e; organização do curso em estudo. Assim, através da análise das assertivas definidas nesses construtos foi possível verificar a percepção dos alunos em relação à disciplina, ao professor e seus comportamentos. É, portanto, uma pesquisa descritiva, de abordagem quantitativa, utilizando-se de testes estatísticos e quanto aos procedimentos adotou-se o survey com aplicação de questionário.
Resultados: Foi evidenciado que mesmo analisando cursos que possuem áreas divergentes de atuação e que apresentam perfis diferentes de alunos, todos os cursos apresentaram discentes que percebem positivamente as variáveis. Destacou-se que existem problemas não só com relação às demandas de disciplinas da área de contabilidade de custos, mas também aos aspectos de dedicação dos alunos quanto ao seu envolvimento e dedicação ao estudo, ressaltando, ainda, a relutância dos discentes em assumir responsabilidades e realizar esforços. Ademais, diferenças nas percepções apontadas nos resultados indicam que, no que concerne aos construtos analisados, há necessidade do aprimoramento da educação contábil.
Contribuições do Estudo: O estudo contribui para que docentes e gestores acadêmicos tomem conhecimento de possíveis fragilidades de métodos de ensino na área analisada a fim de que ocorra orientação para melhorias no ensino, visto que é uma disciplina que está presente nas matrizes curriculares de diferentes cursos de ensino superior e com índices elevados de reprovação.

Published: January 2019

Purpose: The research This work aimed to analyze the influence of organizational complexity on the measurement of biological assets in the public companies listed in B3.
Methodology: To do so, a descriptive, documental and quantitative research was carried out by means of a document, with data obtained through the Economática® database and also in the electronic site of B3. The sample consisted of a set of all the companies listed in B3, however, the sample refers only to the companies that have disclosed biological assets of short or long term in their statements in the balance sheet.
Results: The results show that there is an influence of the organizational complexity for the measurement of the biological assets. The multiple regression model explains that 54% of the changes in the measurement records of the companies' total biological assets can be explained by the variable Log_At total according to the predictive model: (Y = 0.654Xi + 0.281x - 0.115 xi + ei). It was verified that, although regarding the form of measurement of the biological assets, the companies of the sample revealed that 72% carry out the valuation of these based on the criteria of the discounted cash flow.
Contributions of the Study: Considering the normative nature of CPC 29 and its impacts on the criteria of evaluations of biological assets and agricultural products, the research produced a predictive model capable of explaining and clarifying that aspects of organizational complexity influence the classification of the criterion of measurement of total biological assets and the predictive model can be very useful to produce information for decision making on the aspects investigated, besides offering an additional theoretical contribution for the advancement of studies related to the identification of the organizational complexity and the criteria of measurement of the biological assets.

Authors: Jalloul Darin , Al Abdullah Jamal , Alaffif Hesham 
Published: January 2019

Background:Attention was paid to the chemical properties of bioactive materials, and the reaction that could occur on their surface.Objective:The evaluation of the chemical properties includes the solubility, water sorption, pH changes and calcium release of two dental materials (BD and GIC). In addition, the morphological structure of each material was studied after its immersion in two different solutions,i.e.deionized water and phosphate solution.Methods:The chemical study was carried out for two sets of samples; 28 samples of each material. Samples were immersed in 10 mL of deionized water and stored at 37 °C for different times. The morphological structure and elemental analysis of BD and GIC samples were studied after immersion in the two solutions for 1, 7, 14 and 28 days.Results:Solubility of BD increased with time reaching a maximum value after 60 days (13.63 ± 2.08%). The solubility of GIC was negatively correlated with time, with a maximum value of 4.11 ± 0.47% for 3 h. The released Ca+2ions varied between 1.0 ± 0.3 mg (3 h) and 5.3 ± 0.8 mg (60 days) for BD. However, calcium was not detected in the GIC samples. The formation of calcium hydroxy-fluorapatites and strontium-fluoro-alumino-silicate, on the surface of BD and GIC, respectively, was clarified for the first time in this study.Conclusion:A comparative study was carried out revealing the difference in the chemical properties and the morphological structure between the two studied materials. The results confirmed the biointeractivity and the bioactivity of BD and GIC.
