The Impacts of Crude Oil Exploitation on Soil in Some Parts of Ogoni Region, Rivers State, Southern Nigeria

Inah Eteng Okon, Chima Okoko Ogba
The study examined the impacts of crude oil exploitation on the soil environment of Ogoni region and also identified action plans for the future management of the region. Composite soil samples were collected at two depths: 0 - 15 cm (surface soils) and 15 - 30 cm (subsurface soils) along different positions of landscape in the four study locations. Samples were analysed in the laboratory within 5 days of collection. ANOVA was use

Adoption and Effect of Vetiver Grass (Vetiveria zizanioides) on soil Erosion in Somodo Watershed, South-Western Ethiopia

Gizaw Tesfaye, Yalemtsehay Debebe, and Tesfaye Yakob
Soil erosion is an important cause of land degradation and consequent to soil fertility which reduces land productivity and production. This problem aggravates in developing countries like Ethiopia. To minimize this challenge, soil and water conservation with proper design is the first choice. The aim of this study was to assess the adoption and effect of Vetiver grass on soil erosion in Somodo watershed. Community mobiliz

Change Detection: Estimating the Footprint of the Kribi Agro-Industrial and Urban Port Complex (Cameroon) from Landsat Imagery

Jean Megope Foonde
In the coastal South region of Cameroon, 26.000 ha of land once covered by forest is doomed by the development of a significant infrastructure: the Kribi Agro-Industrial and Urban Port Complex. Important earthwork was undertaken to set-up this “structuring project” which is presented as the ultimate propeller for the industrialization of the entire Central Africa region. This paper is the firs

Salinity Variations over Zhejiang Province Waters, China

Xiaohui Zhao, Feng Gui, Venkata Subrahmanyam Mantravadi, Liuzhu Wang
In this article, we analyzed the monthly, seasonal and annual salinity variations and their relations with sea surface temperature (SST), rainfall over the Zhejiang province from 2005 to 2017. SST and rainfall were chosen as the main influence factors. There is an inverse relationship between rainfall and salinity. And the SST has a positive relation with salinity, showing slightly seasonal difference. The vertical variation is ch

Technical Feasibility of Hermetia illucens in Integrated Waste Management, Renovated with Sewage Water, an Overview

Atun Roy Choudhury, Ashok Kumar Natarajan, Srinivas Kesavarapu, Arutchelvan Veeraraghavan, Sandeep Kumar Dugyala, Koteswara Rao, Krishna Rao Thota
In last one decade, numerous researches have been performed on the Black Soldier Fly (BSF) larvae to establish the optimal breeding condition in con-tradiction of the computational temperature, wide sort of substrates and sub optimized feeding ratio. Even though the considerable number of methods has been already established and supervised, there have been a technical lagging always been predominantly in the form of egg hatching r

Application of PSCF and CWT to Identify Potential Sources of Aerosol Optical Depth in ICIPE Mbita

Misiani Zachary, Lun Yin, Mwai Zacharia
This paper evaluates the effects of long-range transport patterns of air trajectories arriving at a rural ground based station, ICIPE Mbita 1125 meters above mean sea level. Mass concentration data of fine mode AOD, coarse mode AOD and fine mode fraction AOD were combined with back-trajectory cluster analysis. The Potential Source Contribution Function (PSCF) model and Concentration-Weighted T

Sustainable Procedure for Using Waste of Date Seeds as a Reinforcement Material for Polymeric Composites

Ali I. Al-Mosawi, Shaymaa Abbas Abdulsada, Abbass A. Hashim
In this article, particles of date seeds as a natural strengthening of the polyester resin and reinforcing percentages (1, 2, 3) wt% were used. For the purpose of comparison with the properties that were obtained in these composite materials reinforced by date seeds, particles have been manufacturing a composite material of the same resin reinforced particles calcium carbonate industrial, the same reinforcing percentages above.

Aerosol Optical Depth Pathways and Sources; Lake Victoria Basin*

Misiani Zachary, Lun Yin, Mwai Zacharia
The air mass back-trajectory clustering analysis was combined with Aerosol Optical Depth (AOD) of fine mode, coarse mode and fine mode fraction in order to evaluate the long-range effects of transportation patterns of trajectories for the ground based station at ICIPE Mbita which is located on longitude and latitude of 34.2°E, 0.417°S respectively at 1125 meters above sea

An Assessment of Jeddah’s Hydraulic Protection and Management Systems of Flood

Atef Belhaj Ali, Faouzi Ameur
Located in the South-west of Saudi Arabia, Jeddah is more than a harbour. It is Saudi Arabia’s biggest Red Sea city and second only to Riyadh the capital. During summer, this metropolis becomes a political capital and a tourist resort for foreigners and Saudis alike. The city of Jeddah was affected by serious and unexpected floods; two great ones took place in 2009, and in 2011. The human and material tolls were considerable, sinc

The Importance of Geothermal Energy Resources in Turkey

Oyku Bilgin
Turkey is located on an active tectonic zone as geological location and the country has a lot of rich in terms of geothermal energy resources. Geothermal energy which is an alternative energy resource has advantages such as low-cost, safe, natural and clean resource. Geothermal energy is defined as hot water and steam which is formed by heat that accumulated in various depths of the Earth’s crust; with more than 20℃ temperature an
