Hydrological regionalization of streamflows for the Tocantins River Basin in Brazilian Cerrado biome
Authors: Rodrigues Jéssica Assaid Martins , Viola Marcelo Ribeiro , Mello Carlos Rogério de , Morais Marco Antônio Vieira 
Published: November 2021

The Brazilian Cerrado biome is the largest and richest tropical savanna in the world and is among the 25 biodiversity hotspots identified worldwide. However, the lack of adequate hydrological monitoring in this region has led to problems in the management of water resources. In order to provide tools for the adequate management of water resources in the Brazilian Cerrado biome region, this paper develops the regionalization of maximum, mean and minimum streamflows in the Tocantins River Basin (287,405.5 km2), fully located in the Brazilian Cerrado biome. The streamflow records of 32 gauging stations in the Tocantins River Basin are examined using the Mann-Kendall test and the hydrological homogeneity non-parametric index-flood method. One homogeneous region was identified for the estimate of the streamflows Qltm (long-term mean streamflow), Q90% (streamflow with 90% of exceeding time), Q95% (streamflow with 95% of exceeding time) and Q7,10 (minimum annual streamflow over 7 days and return period of 10 years). Two homogeneous regions were identified for maximum annual streamflow estimation and the Generalized Extreme Value distribution is found to describe the distribution of maximus events appropriately within the both regions. Regional models were developed for each streamflow of each region and evaluated by cross-validation. These models can be used for the estimation of maximum, mean and minimum streamflows in ungauged basins within the Tocantins River Basin within the area boundaries identified. Therefore, the results provided in this paper are valuable tools for practicing water-resource managers in the Brazilian Cerrado biome.

Removal of nutrients from aquaculture residual water: A review
Authors: Cargnin Jéssica Mendonça Ribeiro , João Jair Juarez 
Published: November 2021

Aquaculture plays an important role in providing protein-rich foods, meeting the growing demand for fish. However, aquaculture is a potentially polluting activity, especially with regard to water pollution, due to the improper disposal of wastewater from the production process. Aquaculture wastewater is rich in nutrients (ammonia, nitrate, nitrite and phosphorus) and organic matter, and is commonly discharged into the environment without proper treatment. This can cause a series of environmental impacts and aggravate the current water crisis. Due to the importance and need to reduce environmental impacts, plan the use of water resources and achieve an efficient and sustainable production process, many researchers have focused their studies on effluent treatment techniques designed to remove these nutrients. This article therefore presents an updated review of the main physicochemical and biological techniques used in the removal of nutrients, which can mitigate environmental problems arising from aquaculture activities and contribute to the sustainability of the activity.
Keywords: biological removal, nitrogen compounds, sustainable activity.
Physicochemical characteristics and green microalgae composition of selected rivers in Ogun State, Nigeria
Authors: Shokunbi O. S. , Badaru A. A. , Adesalu T. A. 
Published: November 2021

The river system is the most complex of the freshwater bodies in the world and is prone to pollution especially from anthropogenic activities and the quality of water, as partially determined by physicochemical properties, is very crucial for primary productivity in the aquatic environment. This study determined the physicochemical characteristics and green microalgae of water collected from Majopa, Ogunpa and Uren rivers in Ogun State, Nigeria. Surface water samples were collected from three different rivers using direct collection method into the labelled bottles for physicochemical characteristics determination, culturing and ecological studies. Water samples for ecological studies were fixed in 4% unbuffered formalin while sample for culturing were not fixed but growth stimulated using Bold Basal Medium (BBM) and Blue- Green Medium (BG-11). The physicochemical parameters varied widely with the profile of water sample from Ogunpa River being the most favourable for widest diversity of green microalgae of all three. The pH of the water samples were slightly acidic ranging between 6.3 and 6.5 for the rivers, while the lower dissolved oxygen (2.61-3.01 mg/L) recorded pointed to a stressed environment which probably accounted for lower number of microalgae taxa observed, especially in Majopa River. The ecological studies showed the presence of ten taxa from the division Chlorophyta with nine taxa from Ogunpa River and Scenedesmus sp. being dominant genus across the rivers. The microalgae diversity of the river water was Ogunpa River˃Uren River˃Majopa River. BBM supported growth of the microalgae much better. The physicochemical properties portrayed Majopa and Ogunpa River water as unfit for drinking, while that of Uren River is relatively fit for drinking. It is highly recommended that the microalgae reported therein be further characterised for various possible economic benefits.

In-vitro antifungal activity of leaf, stem bark and root extracts of Irvingia gabonensis against fungi associated with its seed deterioration
Authors: Gbadamosi I. T. , Obanubi O. T. , Sobowale A. A. 
Published: November 2021

Irvingia gabonensis (Aubry-Lecomte ex O'Rorke) Baill seeds are often contaminated in storage by postharvest spoilage fungi. This study investigated the nutritional contents of the seeds, phytochemical contents and antioxidant activity of different parts of the plant as well as their antifungal effects against fungi isolated from the deteriorated seeds. Proximate, mineral and phytochemical analyses were carried out using standard laboratory techniques. The antioxidant activity was against DPPH radicals. Ethanol extracts (100 and 200 mg/ml) of the various parts were screened against the isolates using pour plate method in Potato Dextrose Agar (PDA) plates. The plates were examined for growth daily for 10 days. Data were statistically analysed. The healthy seeds contained higher protein (13.73%), fat (58.73%) and fibre (2.50%), whereas, higher content of moisture (10.17%) and carbohydrate (15.47%) were observed in the spoilt seeds. The leaf had highest contents of alkaloids (1228.3 mg/100 g), flavonoids (1345.9 mg/100 g), tannins (1345.9 mg/100 g), saponins (578.3 mg/100 g) and carotenoids (2348.3 μg/100 g). The antioxidant activity of the leaf (50.30%) was the highest. Fungi isolated from the deteriorated seeds were Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus and Curvilaria lunata. The leaf was most effective against A. niger, A. flavus and C. lunata whereas the stem bark extract was most effective against A. fumigatus. The F-values were significant for model, treatment, concentration and number of days for the leaf and root. This study confirmed the antifungal activity of extracts of various parts of the plant against isolates implicated in the deterioration of its seeds. The extracts could be used as preservative to enhance the shelf-life and nutritional quality of the seeds.

The use of smoking kiln for drying catfish is on the increase in Nigeria due to its effectiveness in reducing moisture and contamination with toxic compounds during smoking. Chemical properties of kiln-smoked catfish in selected locations in Ilorin metropolis were determined in this study. Kiln-smoked catfish were obtained from four major locations (Oyun, Asa-Dam, Tanke and Agbo-Oba) in Ilorin, Nigeria. The samples were subjected to chemical and polycyclic hydrocarbon content analyses. Dried catfish from all the locations had low moisture and crude fibre contents. There were no significant differences (p>0.05) in the crude fibre contents of the kiln-smoked catfish. Protein contents ranging from 53.72-56.49% were obtained for the kilnsmoked catfish samples. Fat contents ranged from 9.92-11.77% while the carbohydrate contents ranged from 19.02-23.59%. Potassium was the most abundant mineral in the samples with no traces of lead and cadmium. Agbo-Oba samples contained the highest pyrene (2983.215 ng/ml) and total polycyclic hydrocarbon (PAHs) (3349.090 ng/ml). Data on steroid fractions indicated that 17b-estradiol was significantly greater in quantity than those recorded from other steroid fractions. Microbial analyses of the samples revealed the presence of the following pathogenic organisms: Klebsiella spp, Salmonella spp, Shigella spp, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, Vibrio spp, Aspergillus niger, penicilium spp, Trichoderma spp which are harmful to man. The use of smoking kiln method improved the nutrients and reduced PAHs in catfish.

Appearance of phenotypic plasticity of leaves in psammophyte Corynephorus canescens during flooding
Authors: Nedukha Olena 
Published: November 2021

The results of the study of the leaf structure in psammophyte Corynephorus canescens, which grew under controlled conditions and flooding using the methods of light microscopy, scanning electron microscopy, and laser confocal microscopy, are presented. This study revealed common and distinctive signs of morphological and anatomical parameters of C. canescens leaves in the phase of vegetative growth. Among the common features were the shape and size of the leaf laminas, hypostomatic type of the leaf, isolateral structure of the parenchyma, the thick-walled epidermis, and the bilayered hypodermis. Among the distinctive features were the signs of the destruction of cells in the photosynthetic parenchyma, change in their shape with the formation of protuberances at the cells’ poles, and almost doubling area of the aerenchyma in C. canescens leaves under flooding conditions. Scanning electron microscopy showed the similarity of ultrastructure and density of trichomes on the adaxial surface, excepting the formation of cuticular wax structures on the epidermal surface of the leaves in flooded plants. The subcellular localization of silicon inclusions was studied for the first time. The presence of amorphous and small crystalline silicon inclusions in the periclinal walls of the main epidermal cells and amorphous silicon inclusions in leaf trichomes was established. An increase in the relative silicon content along the trichomes in the leaves’ epidermis after flooding was revealed. It was assumed that the phenotypic plasticity of C. canescens, is realized through the increasing area of aerenchyma in leaves and increasing silicon content in trichomes. Such plasticity helps to optimize both the oxygen balance of plants and water balance in flooded plants, thus increasing the species’ resistance to prolonged flooding.

DILEMA DISTRIBUTIVO DAS PETROFEDERAÇÕES: COMO ESCAPAR DA MALDIÇÃO DOS RECURSOS NATURAIS?
Authors: Natalino Enrique 
Published: November 2021

O trabalho se propõe é analisar o problema da Maldição do Petróleo sob a perspectiva dos petro-Estados e das petrofederações, abordando as diversas experiências de Estados que possuem economias voltadas, em maior ou menor grau, à exploração do petróleo, bem como os diversos arranjos institucionais e distributivos existentes. A existência de uma relação entre a instabilidade econômica e política de nações que exportam petróleo e a existência de instituições fracas é um tema estudado pela literatura da Economia Política há várias décadas. Tanto a estruturação do Estado quanto os arranjos políticos distributivos construídos sob a égide de um modelo dependente do petróleo teriam enrijeceriam as possibilidades de escolhas de escolhas desses países, ajudando a explicar as suas trajetórias. Utilizando abordagens neoinstitucionalistas (KARL, 1997; ROSS, 2015), procura-se mostrar como a administração de problemas econômicos nos petro-Estados dependeu de um conjunto de incentivos e regras que balizaram os atores políticos, afetando decisivamente os resultados alcançados. Nesse sentido, o paper buscou analisar o impacto da redistribuição das rendas do petróleo em federações como Brasil, Argentina, México, Canadá, Estados Unidos, Rússia, Índia, Nigéria e Austrália para entender se a maior descentralização ajudaria a combater ou agravaria os problemas advindos da Maldição dos Recursos Naturais. Ao invés de crescimento econômico e distribuição de renda, ao serem mal administrados e distribuídos, os recursos do petróleo levariam a padrões rentistas de comportamento, ao descontrole fiscal, à redução da diversificação econômica, agravando a desigualdade, a corrupção e podendo levar, no limite, a saídas autoritárias e a conflitos armados.

Core Assumptions and the Competitive Advantage among Commercial Banks in Kenya
Authors: Waithaka Paul 
Published: November 2021

Purpose: This paper sought to examine the effect of verification of core assumptions on the competitive advantage among commercial banks in Kenya.
Methodology: The target population for the study were directors or managers in-charge of planning or strategy in each of the forty banks in the country. Primary data was collected using a semi structured questionnaire. The questionnaire was tested for both validity and reliability and was found to meet the required threshold. . Data was analyzed using both descriptive and inferential statistics. Analysis was done with the assistance of SPSS computer packages.
Findings: A response rate of 77.5% was achieved in the study and this was adequate for analysis. The study found that verification of core assumptions has a β =0.472 and a p-value of 0.000 which indicates that it has a significant effect on the ability of banks to sustain competitive advantage. The study therefore concluded that verification of core assumptions must be carried out continuously to track their validity on which the company’s strategies are grounded upon.
Unique Contributions to Theory, Practice and Policy: The study therefore recommends that banks should raise the level of use of competitive intelligence in monitoring the competitive landscape to enable early verification of core assumptions. The study further recommends that banks should continuously monitor the various core assumptions that were considered during strategy formulation to verify their validity to enable the bank rapidly change the strategy, should the core assumption on which it was grounded on be found to be no longer valid.
