Benue - Congo languages
endangered languages
Opis:: Àhàn and Àyèré are two endangered languages spoken respectively in Nigeria. This paper describes the process of genitive construction in the two languages showing how close they are to some Benue – Congo languages in the derivation of genitive. Findings show that genitive marker in both Àhàn and Àyèré is / ólí / as found in some Benue-Congo languages such as Yorùbá, Igede, Èbìrà and Ukaan. The paper further reports that Àyèré has another marker /óní/ that appears to perform the function of deriving genitive ,however the marker, along with the nominal prefix /a/, derive a form that has the semantic coding of “a person who does a particular thing”.

Opis:: The potential of rice husks powder (RHP), for the removal of Congo red dye from aqueous solution was investigated. Batch adsorption studies were conducted and various parameters such as contact time, adsorbent dosage, initial dye concentration, pH and temperature were studied to observe their effects in the dye adsorption process. The optimum conditions for the adsorption of CR onto the adsorbent (RHP) was found to be: contact time (100 min) pH (10.0) and temperature (303 K) for an initial dye concentration of 50 mg/l and adsorbent dose of 1.0 g respectively. The experimental equilibrium adsorption data fitted best and well to the Freundlich Isotherm model for both dyes adsorption. The maximum adsorption capacity was found to be 33.88 mg/g for the adsorption of CR dye. The kinetic data conformed to the pseudo second order kinetic model. Thermodynamic quantities such as Gibbs free energy (ΔGº), enthalpy (ΔHº) and entropy (ΔSº) were evaluated and the negative values of ΔGº, ΔHº and ΔSº obtained indicate the spontaneous and exothermic nature of the adsorption process.

Tytuł:: President Trump’s threats in coltan supply chain due diligence stunt Congo’s 2020 nation branding vision

Nation branding
The 2010 Dodd-Frank Act
Opis:: The DR Congo is one of the African countries rich in minerals ranged from amblygonite to Zinc. However, only three African countries namely Botswana, Namibia and South Africa are known as mineral-dependent economies which do not suffer from “the curse of minerals”. In 2006 Atalli predicted the collapse of the DR Congo owing to various reasons including large scale corruption in the coltan supply chain. Thus, the 2010 Dodd-Frank Act requiring any company that might be using conflict minerals to register with the US Securities and Exchange Commission and then disclose its supply chain was introduced. As such, the Act curbed the fate of the “curse of minerals in the DR Congo”. However, the problem is that president Trump’s executive order to review the Dodd-Frank Act in effort to allow US companies to profit from armed-conflicts minerals threatens existing due diligence framework in coltan supply chain. That review has the potentials to fuel armed-conflicts, creates opportunism, erode relational norms, trust; thus undermines the country’s 2020 nation branding vision as emerging business destination. The study objective is to evaluate the impact of Trump’s Dodd-Frank Act revision in the coltan supply chain in the DR Congo and the country’s 2020 nation banding vision. The study focused only on the implications of Trump’s threats in coltan supply chain in the DR Congo; thus alternatively excludes other type of minerals. Hence, it contributes to the body of knowledge by providing new insights into nation branding theory and Congolese coltan supply. The study adopted a case study approach which was grounded in the theoretical framework of nation branding. The nature of study dictated qualitative and quantitative methodologies combined. Survey questionnaire and focus group techniques were used. The sample size N=74 respondents from coltan buying organisations was used. Non-probability purposive sampling method was employed.

Opis:: Drought poses one of the most important environmental constraints to plant survival and productivity and by implication-food insecurity in the tropics. Pigeon pea (Cajanus cajan) has the potential of fertilizing the soil thereby improving agricultural production and ensure green environmental and ecosystem stability. Despite the ability of the plant to improve soil fertility and promote greening environment, it has not attracted adequate awareness as a soil improvement plant. This paper highlights the information on the plant in order to intensify awareness for its widespread adoption to achieve the much desired sustainable resource use for greening our economy and environmental management. The successful widespread adoption of the plant will translate to effective drought, desertification and sustainable climate change mitigation approach in Nigeria.
