Proteus 170O - TEQ insecticide was subjected through rigorous testing over years (2005 to 2008) at four concentrations 0.15% (9 mls/10L.H20), 0.31% (18 mls/10L.H2O), 0.46% (27 mls/10L.H2O) and 0.61% (36 mls/1... Proteus 170O - TEQ insecticide was subjected through rigorous testing over years (2005 to 2008) at four concentrations 0.15% (9 mls/10L.H20), 0.31% (18 mls/10L.H2O), 0.46% (27 mls/10L.H2O) and 0.61% (36 mls/10L.H2O). Each concentration was replicated three times in the field. The mortality rates of mirids on exposure to the various concentrations of Proteus and Standard miricide in the laboratory were similar at 0.46% concentration as both gave a 100% kill ofmirids at the 40th minute. The first year field mortalities of mirids recorded 24 hours after the initial and residual applications at the Ibadan, Owena and Ikom at 0.46% active ingredient concentration gave 100% kill of mirids. The mortalities of mirids recorded 24 hours after the second year field initial and residual treatments at the lowest concentration of 0.15% active ingredient ranged between 70.2% and 100%. In the third year, the insecticide at 0.31% concentration compared favourably with the Standard. The residues of thiacloprid in the analyzed cocoa bean samples were below the Limit of Quantitation (LOQ) of 0.01 mg/kg. Spraying of mature and fruiting cocoa farms at application rate of 0.46% was found adequate and recommended. 展开更多

The concept of justice is a complex phenomenon which has been subjected to various legal, social, and philosophical interpretations. In other words, for the concept to make meaning to analysts and various intellectual communities, it has to undergo a process of concept conceptualization and operationalisation. It is therefore this lack of univocal definition of justice that one can philosophically assert that there is no theory of justice but theories of justice. The purpose of this article is not to delve into the various analyses of theories, meanings, definitions, and/or explanations of justice but to examine John Rawls' Difference Principle of justice in the context of the Nigerian Quota System. In order to make this writing less nebulous and less ambiguous and more explicit and clear, I shall examine the definitions of the concepts of both justice and Quota System. In addition, evaluation of the philosophical and theoretical assumptions of the Rawls' theory and the Quota System will be made with a view to revealing their applicability and relevance in our real economic socio-political system (in Nigeria). 展开更多
