Dredge Volume Calculation Using Grid Volume Model at Sharm Obhur, Red Sea—A Case Study

V. R. Shamji
Calculation of dredging volume is very critical for project estimation and implementation. Many methods are available to compute the dredging volume and most of them are complex and expensive too. This paper pro-poses a simple grid volume numerical model to calculate the dredging volume. A case study conducted at Sharm Obhur, the Red Sea, using the grid volume model and quantitative analysis, was carried out. The study pointed out

Effect of Cadmium Repartition on Nitrogen Metabolism in Tobacco Seedlings

Houda Maaroufi Dguimi, Khulud Alshehri, Chokri Zaghdoud, Ali Khalaf Albaggar, Mohamed Debouba
Thirty-day-old tobacco seedlings (Nicotiana tabaccum, Bureley v) were subjected during one week to increasing cadmium (Cd) concentrations (0, 10, 20, 50 and 100 μM CdCl2). Increasing Cd stress led to a gradual decrease of dry weight (DW) production, water and nitrate contents. More than the half of Cd accumulated per plant was sequestered in the oldest lea

The Implications of the Shift towards Standard Financial Reporting Specialist for Small and Medium-Sized Companies to Attract Foreign Investment in the Iraqi Environment

Sadeq Musdeq Hassan ALasdy, Baker Ibrahim Mahmoud
Small and medium-sized entites (SMEs) are the main backbone of the economy of any country, whether developed or developing, where these companies are characterized by their high capacity to provide jobs, and are the main drivers of further technological innovations and are therefore considered one of the main engines of the growth of the economy. Given the importance of the role played by small and medium-sized entites (SMEs), the

Hungry for Styrofoam: Mealworm’s Solution to the Great Pacific’s Garbage

Cameron A. Stewart
Polystyrene, a recyclable material, used in packaging, drinking containers, and to-go boxes are linked to 30% of the materials in landfills. How do we cost effectively to solve this problem? Why is nothing being done about this? Will polystyrene ever become obsolete?

How Should We Manage China’s National Parks? A Comparative Analysis between National Parks in China and the US

Linghong Kong, Yangcui Ning, Long Chen
This paper analyses the differences between policies in Chinese and American national parks, including the role of communities, the permitting and reservation system, and camping. It also describes additional recom-mendations related to developing community-based tourism, the e-commerce market, and data statistics tools. What is the best way to support communities economically at the boundaries of national parks? The American expe

Case Study of Baiyun and Caohai Lakes Implies How to Implement Wetland Restoration/Creation

Lin Xiao, Qun Zhang, Guifeng Wei, Sixi Zhu, Fanyang Yu, Boping Han
This work discusses how to implement wetland restoration/creation from the viewpoint that wetland aquatic plants are divided into four life forms: emergent, submergent, floating and floating leaf plants. Caohai Lake and Baiyun Lake were selected to discuss the difference of the species richness changes during the creation/restoration process. Baiyun Lake and eight surrounding wetlands have been selected to discuss how the species

Seasonal Variability in Aerosol Microphysical Properties over Selected Rural, Urban and Maritime Sites in Kenya

Geoffrey W. Khamala, Jared O. Odhiambo, John W. Makokha
Atmospheric aerosols are posing a great threat to the already stressed climate with the effects being felt more on African continent. Their presence and interaction with the clouds contribute to the strongest uncertainty in aerosol characteristics and Earth’s energy budget hence; calling for a long term assessment to be done. The present study analyses long term spatiotemporal microphysical aerosol characteristics (namely: effecti

Methane Gas Emissions: Methods of Improving the Efficiency of the Biggest Landfill Gas Waste to Energy Project in the Middle East Installed in Amman, Jordan

Constantine Hadjidimoulas
In a world of increasing population and consumption, there is a pressing need to use our resources in the best possible way. This involves reducing the generation of waste, achieving high-quality recycling and efficient use of the residual waste for highly productive clean energy generation. A waste-to-energy facility may generate a range of energy outputs such as electricity, district heating, steam for industrial processes and m

Optical Characterization of Atmospheric Aerosols via Airborne Spectral Imaging and Self-Organizing Map for Climate Change Diagnostics

John W. Makokha, Jared O. Odhiambo
Self-Organizing Map (SOM) analysis is used to perform optical characteri- zation of both Aerosol Optical Depth (AOD) and Angstrom Exponent (AE) retrieved from Moderate-resolution Imaging Spectroradiometer (MODIS) in relation to Precipitation Rate (PR) from Tropical Rainfall Measurement Mission (TRMM) over selected East African sites from 2000 to 2014 and further diagnose climate change over the region if any. SOM reveals a marked

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
