This study aimed to evaluate the chemical composition, fractionation of nitrogen compounds and carbohydrates, digestibility parameters, gas production kinetics and ruminal fermentation of fruit seed cakes. The experiment was conducted in a completely randomized design with three fruit seed cakes (treatments) and four replications. The cakes were made of seeds of custard apple (Annona squamosa), soursop (Annona muricata) and passion fruit (Passiflora edulis), which were collected in a biodiesel plant. The passion fruit seed cake presented the highest content of dry matter, neutral detergent fibre crude protein (NDFcp), acid detergent fibre (ADF), lignin and total carbohydrates (P<0.05). The custard apple seed cake presented high proportions of crude protein, condensed tannins and digestible energy (P<0.05). The soursop seed cake presented higher values for ether extract and total digestible nutrients (P<0.05). For potential degradability, the authors detected a difference between the custard apple, soursop and passion fruit seed cakes. The total volume of gases was higher for custard apple and soursop seed cakes. Custard apple seed cake presented higher proportions of in vitro degradation parameters (P<0.05). Thus this cake could provide greater nutrient levels when supplied in ruminant diets, followed by soursop seed cake and passion fruit seed cake.

The presence of dragonflies and damselflies may be taken as an indication of good ecosystem quality. The greatest numbers of species are found at sites that offer a wide variety of microhabitats. A survey of Odonata fauna inhabiting the University of Lagos, Akoka Lagos, south-west Nigeria was carried out between July and December 2014, with a view of determining its diversity and distribution. Four study sites used were Distance Learning Institute (DLI), Lagoon, Faculty of Science, and High Rise Area. Data collected were subjected to inferential statistics and analysis of variance (ANOVA). Diversity indices were used to compare the odonate species in the study sites. Seven hundred and fifty (750) individuals representing 39 species in 22 genera and four families (Aeshnidae – 3%, Coenagrionidae – 13%, Libellulidae – 81% and Calopterygidae – 3%) were recorded. Orthetrum (18%) was the most dominant genus, followed by Ceriagrion (10%) while Palpopleura and Trithemis (8%) were the least dominant genera. The site with most diverse Odonata fauna (H’ = 2.70, E = 0.27), was High Rise Area while the least was the Lagoon Area (H’ = 1.97, E = 0.27). Odonata in High Rise Area were significantly lower (p>0.0128) than those in DLI and Science Area which were not significantly different from each other (0.00039 and 0.00368 respectively). The paucity of species with narrow range of adaptation at the university especially at Lagoon Area where they were expected to occur is an indication that the forested part of the campus is under considerable human disturbance. Urgent measures are needed to preserve the natural the natural habitats of these Odonata species.

Effects of bottom-up and top-down interactions on the productivity of Iyieke Lake, Afikpo North, Ebonyi State, south-east Nigeria
Authors: Nwonumara G.N. , Idumah O.O. 
Published: June 2020

The bottom-up and top-down interactions of the abiotic and biotic components of Iyieke Lake were studied for eleven months covering a pre-flood, flood and post-flood periods. During the study, some water quality parameters were measured while plankton samples were collected for identification in the laboratory using standard method. The results of the water quality parameters measured showed that water temperature was highest (35.00R”C) in February. pH (7.10) and transparency (0.98 m) were highest in August. Highest TDS (28.0 mg/L) and conductivity (56.00 μS/cm) were recorded in March (pre-flood period) while dissolved oxygen level was lowest (4.00 mg/L) in the pre-flood period (February and March). Nitrate (0.18 mg/L) was highest in August (flood period) and phosphate (0.25 mg/L) at the two extreme periods (pre-flood and post flood). The depth of the lake was highest (3.2 m) in August which was the period of inundation. The phytoplankton (Bacillariophyta, Chlorophyta, Cyanobacteria) and zooplankton (Rotifera, Cladocera, Copepoda) of the lake were made of three divisions and taxa each, respectively. Bacillariophyta dominated among the phytoplankton while Rotifera was the most abundant among the zooplankton. The study revealed that nutrients and zooplankton grazing were the major factors that affected phytoplankton abundance and biomass during the study.

Published: June 2020

Snappers are highly recommended as choice seafood and as viable candidate for cage culture in the brackish water and marine environments. However, very limited data exists on biological parameters of the snappers, Lutjanus species throughout their distribution range. Hence, the present study sought to improve knowledge on Length-Weight Relationship (LWR) and relative condition factor (Kn) of the Gorean snapper, Lutjanus goreensis (Valenciennes, 1830) sampled between December 2008 and December 2009 in the coastal zone of Lagos, Nigeria. Specimens were collected from landings of artisanal fisheries and inshore trawl fisheries. A total of 822 unsexed estuarine (7.90 to 34.90 cm and 9.51-695.60 g) and 377 sexed marine (21.90 to 56.10 cm and 156-2 975 g) specimens were analyzed. The overall value of the slope, b for the LWR indicated negative allometric growth for unsexed estuarine (2.860); marine male (2.856) and female (2.917) specimens, respectively. The relative condition factor, Kn did not vary significantly from 1. Sex-wise variations of b values and Kn were not significant either. The present study presents, for the first time, baseline information on the length-weight relationship parameters and condition of L. goreensis in the marine waters of Nigeria and in the Eastern Atlantic Ocean. The results are useful indicators to assess the well-being of wild Gorean snapper populations in Lagos coastal zones for management and under culture conditions.

Published: June 2020

The need to screen new rice genotypes for resistance to stored product insect pests is important to boost production and availability of rice for food security. Therefore, thirteen rice genotypes and varieties included ten interspecific rice genotypes from two crossed parents Oryza sativa (WAB 56-104) and Oryza barthii (IRGC 106107), the two parents and NERICA8 variety were collected from Africa Rice Center, International Institute of Tropical Agriculture (IITA) Ibadan, to examine their resistance level to infestation by Sitophilus oryzae L. and Rhyzopertha dominica F. The resistance of the varieties were assessed by artificial infestation with 12 unsexed adults each in 10 g of the rice varieties in four replicates under laboratory conditions of 26 ± 2oC temperature and 75 ± 5% relative humidity in a completely randomized design. Number of adult insect emergent, per cent grain damage, percent weight loss of infested samples and index of susceptibility were determined. Correlation analysis between nutritional contents of the varieties and infestation variables were also obtained. Results indicate differential responses of the two insects on the rice genotypes/varieties. The O. barthii parent was resistant, while the O. sativa parent was moderately resistant using the susceptibility index. Of the ten rice genotypes, G4, G3, G1, G7, G2, G10 and G9 were resistant in descending order, while G5 and G6 were moderately resistant, whereas only G8 was susceptible. NERICA8 was also found to be susceptible to infestation. In addition, the resistant grains had lower ash content. Modification in genetic variations and nutritional contents of new rice varieties may be a critical factor in insect resistant genotype pro-grammes to reduce post-harvest losses incurred by farmers.

Authors: Badejo Omobola Olufunto 
Published: June 2020

At the rise of the twentieth century, armed with the success of natural sciences, the school of naturalism argued that the appropriate methodology for all disciplines, including social sciences, is that of natural science. The paper argued that social sciences cannot be naturalised and has its own appropriate methodology. The paper examined the arguments for naturalism and non-naturalism of the method of philosophy of social sciences. The paper employed both primary and secondary sources of data. Data collected were subjected to critical analysis and philosophical argumentation. The results showed that the nature of social sciences is such that it cannot be subjected to only scientific methods. The paper concludes that there is a need for a methodology that understands the subject matter of social sciences to address issues in social sciences. The paper addressed some key issues in philosophy of social sciences.

Editorial: Knowledge democracy for a transforming world
Authors: Hall Budd , Tandon Rajesh 
Published: June 2020

The past five decades have seen enormous, worldwide growth in, and appreciation of, knowledge democracy – the discourse which we have found best contains the various theoretical approaches, values and practices within which participatory research exists. This Introduction outlines our understanding of knowledge democracy, which can be expressed by a number of principles: (1) Recognition of a multiplicity of epistemologies and ways of knowing; (2) Openness to assembling, representing and sharing knowledge in multiple forms (including traditional academic formats and all manner of social and arts-based approaches); (3) Recognition that knowledge emerging from the daily lives of excluded persons is an essential tool for social movements and other transformational strategies; and the (4) Requirement to carefully balance the need to protect the ownership of communities’ knowledge with the need to share knowledge in a free and open access manner. We are pleased to present five articles from around the world that broaden and deepen our understanding of knowledge democracy – from a theoretical perspective, a practice perspective, an ontological perspective, and an action or political perspective.

Authors: Gandžalová Lucia , Pacalajová Nikola 
Published: June 2020

The centre of main interests is the key concept of Regulation (EU) 2015/848 of the European Parliament and of the Council of 20 May 2015 on insolvency proceedings. Its significance lies in the fact that this concept constitutes the sole determinant for establishing international jurisdiction for the opening of the main insolvency proceedings. The paper deals with the analysis of the concept of COMI, including the presentation of the case-law of the Court of Justice of the European Union.

The Aftermath of the Achmea Case
Authors: Profeldová Tereza 
Published: June 2020

The paper deals with the implications arising from the Achmea judgment which are far reaching not only for the arbitration community. With regard to investment arbitration, the decision controversially excluded the possibility of arbitration agreements in BITs concluded between EU Member States. The lack of proper reasoning concerning individual arguments used by the CJEU is discussed. The judgment is also being taken as example of increasing practice where decisions are being made based on political needs rather than as a result of legal assessment.

Published: June 2020

Soil fertility depletion due to soil erosion and nutrient leaching caused by heavy and continuous rainfall is one of the major causes for declining of soil productivity and crop yields in Masha district of south-western Ethiopia. Soil Hence, a field experiment was conducted in Belg and Meher seasons at Abelo area, Masha district, south-western Ethiopia, to determine the effect of combined application of cattle manure (CM) with inorganic nitrogen (N) and phosphorus (P) on potato tuber yield, and selected soil physico-chemical characteristics. The treatments comprised of combinations of three rates (2.5,5, 7.5 t ha-1) of CM with 25%, 50% and 75% of recommended rates of mineral NP, respectively. In addition, 100% recommended rate of mineral NP (165 kg N ha-1 and 137 kg P2O5 ha-1) and zero rates were used for comparison. The experiment was laid out in a randomized complete block design with three replications. The results revealed that applying 7.5 t ha-1 CM combined with 75% mineral NP gave significantly highest potato total tuber yield of (40 and 34 t ha-1), the same rate increased tuber yield by 55.9% and 43.45% in Belg and by 51.19%, and 36.64% in Meher over the control and the application of 100% recommended rate of NP fertilizers, respectivelysoil pH (5.15 and 4.94), Organic carbon (21.1and 12.7 g kg-1 ), total N (1.71 and 1.51 g kg-1), available P (7.55 and 6.27 mg kg-1), CEC (22.04 and 23.96 cmol (+) kg-1 ), exchangeable Ca+2 (8.36 and 8.28 cmol (+) kg-1), exchangeable Mg+2 (3.14 and 2.06 cmol (+) kg-1), total porosity (51.1 and 54.97%) more over the treatment decreases exchangble acidity (2.32 and 2.08 cmol+kg-1) and exchangble aluminum (1.46 and 1.41 cmol(+) kg-1), bulk density (1.07and 1.30g cm-3) in Belg and Meher seasons, respectively. Therefore, it can be concluded that the use of combined application of 7.5 t of ha-1 CM together with 75% of recommended rates of inorganic N (123.75 kg N ha-1) and P (103.05 kg P2O5 ha-1). can significantly increase potato tuber yield and improve the soil properties and reduces soil acidity.

Published: June 2020

Some physico-Chemical parameters of Manatee habitat along river Benue were conducted. The river was divided into four segments; Makurdi, Abinsi, Gbajimba and Gbaji. In each srgment, ten (10) sample points were chosen and the following parameters ; Temperature, dissolved solid (D0), pH, Total dissolved solid,(TDS) Electrical conductivity (EC) and Biological oxygen demand (BOD) were measured. Data collected was subjected to statistical analysis. The result indicated that there were significant differences in the pH, Electrical conductivity, and Biological oxygen demand (BOD) among the four study areas. The mean pH ranged between 6.94 to 7.09, EC ranged between 47.76 µs/cm -55.91 µs/, dissolved oxygen was between 15.82Mg/L in Makurdi to 18.50Mg/L in Abinsi, mean Temperature moved between 29.27oC in Makurdi to 34.33oC in Gbaji, the total dissolved solids ranged from 44.46 Mg/l in Abinsi to 56.74Mg/L in Gbajimba while Biological Oxygen demand (BOD) was least at Gbajimba( 3.03 Mg/L) and Makurdi with 5.49Mg/L It is therefore suggested that continuous monitoring of the water health of the river be sustained for the survival of the west African manatee.
THE USE OF ENRICHED ORGANIC FERTILIZER TO REDUCE ORGANIC AND INORGANIC FERTILIZER APPLICATION AND INCREASE POTATO YIELDS IN THE HIGHLANDS OF INDONESIA
Authors: Hilman Yusdar 
Published: June 2020

The use of Enriched organic fertilizer to Reduce organic and Inorganic Fertilizer Application and Increase the Potato Yields in the Highlands of Indonesia. Experiment was conducted at Experimental Station of Indonesian Vegetable Research Institute (the elevation of this site is 1250 meters above sea level) from June to November 2017. The objective of the experiment is to obtain an efficient technology of nutrient management in terms of organics and biological fertilizers and to obtain appropriate technology of potato tuber. The implementation of the reseach was preceded by making compost manure using Bio-decomposer for one month and enriched by using Bio-Phosphate and benficial Micro-organism, dolomite, ash husk and rock phosphate, then continued with its application in the field with potato as an indicator plant. The treatments were arrange in a randomized complete block design (RCBD) with four replications. The treatments included the use of organic fertilizer in terms of horse manure enrichment at a rate of 20 and 40 t/ha and inorganic fertilizer at a rate of 0, 500 and 1000 kg NPK and horse manure 40 t/ha + 1000kg NPK/ha as control plants (farmer's practice). Results of the experiments indicated that the use of horse manure enriched by microorganism can reduce a rate of hord=se manure from 40 ton/ha to 20 t/ha to produce growth and yield of potato. Enriched horse manure can also reduce the use of inorganic fertilizers by half rate ( 500 kg NPK / ha). Combination of enriched horse manure 20 t / ha + 500 kg NPK / ha is more efficient to increase yield of potato tubers. The use of enriched horse manure does not seem to affect the improvement of soil fertility, especially for the availability of soil P and soil biological activity. Keywords: Solanum tuberosum, horse manure, decomposer microbes, inorganic fertilizers, tuber yields.
