Natural Resources are available in plenty and widely spread over different regions of the world, some of them discovered and many still to be discovered. Man is impatient to consume the available natural resources without counting the cruelty and consequences of doing so. World over natural resources are depleting, and there is inadequate perception and very little action to prevent such irresponsible act. There is a very urgent need to create awareness among countries and people about the depleting resources and the need to prevent over consumption and depletion of resources. The efforts to regenerate natural resources are lacking and before long human beings will realize their folly – but will it be too late? World over politics has taken over the destiny of humans and the commonsense has become most uncommon among the people of this planet. The present research paper is to focus attention on this important human problem with the fond hope that creative solutions will be forthcoming from all parts of the planet for the benefit of human civilization. For the purpose of the current research paper specific objectives have been identified to have a better focus.

Color images are an important digital type,  they are used in many vital applications which require a high speed processing, so creating a color image features is a an excellent issue. In this research paper we will study famous methods of features extraction, we will implement them, and the obtained experimental results will be compared, efficiency parameters such as extraction time and throughput will be obtained and a speedup of each method will be calculated. Image histogram will be used to improve the efficiency and make the extraction method insensitive to the image rotation.

China’s economic evolution over the past year, two decades has generated Ripple effects in the world economy particularly in African continent .China-Africa relations are one that have been ongoing for centuries transcending to present day, however their investment and trade have mushroomed over the last 10 years. it’s economic impact to the region is both huge and far fetching especially in the sub Saharan Africa with its biggest investments made in Nigeria, South Africa, Sudan and Angola. Chinese investment abroad though Foreign Direct Investment ( FDI ) and Angola Mode has subsequently increased especially in natural resources to satisfy it’s growing demand of industrialization ,the trade between China and Africa totaled to more than 50 billion in 2006 with Chinese companies importing oil from Angola and Sudan ,Timber from Central Africa and copper from Zambia, this particular kind of assistance has not been received well by the western politicians as they are worried China is conducting a new form of imperialism in Africa, however Chinese aid bares no political influence or pressure for political change, thus makes more lucrative deal. The growing mutual benefits have prompted the development of a new and stable partnership by offering aid without preconditions. China has therefore presented an attractive alternative to that of conditional western aid. In this context, it is of great importance to explore China’s Foreign Direct Investment in Angola with the objective of understanding the barriers, regulation and economic environment of Angola and understand the impact of these historical phenomenon .The study analyzed the impact of Chinese foreign direct investment on Angola economic growth over the period of 2003- 2017. The Ordinary Least Square (OLS) of multiple regression method is the estimation technique that is being employ in this study to determine the relationship between Chinese FDI and Angola’s GDP growth, the findings revealed that Angola economic growth is directly related to Chinese foreign direct investment and it is also statistical significant at 99% level which implies that foreign direct investment is an engine of economic growth. The paper recommended that government should liberalize the foreign sector in Angola so that all barriers to trade such as arbitrary tariffs; import and export duties and other levies should be reduced so as to encourage investors.

Constructing distribution substations is capital intensive and hence is the best practice in order to obtain optimum profit. Nevertheless, most power distribution companies in Eastern part of Nigeria operate within the substations with equipment and materials that cannot restrict the targeted projected lifespan of the equipment. This study however investigates critically the actual cost of building a typical substation using Eastern part of Nigeria as a case study. The substations consist of New Haven, Abakaliki, Nkalagu, Onitsha, GCM, Awka, Agu Awka, Oji, etc. To determine the cost effective management of these substations, so many questions were raised and analysed in SPSS environment., Z-test was also carried out using Pearson’s approach and the result gave no significant difference since the calculated z-values of 0.52 and 1.07 were less than the critical value of 1.96, hence two formulated hypotheses were found satisfactory
