Climate change is one of the greatest challenges worldwide. Its most severe impacts may still be avoided if efforts are made to transform current energy systems. The notion of climate change mitigation refers to the reduction of the rate of climate change via management of its causal factors such as the emission of greenhouse gases from fossil fuel combustion, agriculture, land use changes, cem...

This paper addresses the relationship between climate change and aquaculture sector through comparing the contribution of developed and developing countries in gas emission (CO2) and aquaculture production. As long as aquaculture industry is vital source of food and revenue for most developing countries, their livelihood presumably would be affected negatively by global warming. Examining data ...

The objective of this paper is to prospect and analyse the main challenges faced when defining and building virtual reality workspaces for Exploration & Production oil & gas activities. Initially, we classify and describe the different challenges. Then, we present the main activities in the oil & gas industry that use this technology.

Due to easy availability of cheaper raw material and increase in new applications, the use of polyolefins in various industries is becoming a major priority. The Middle East region, on account of its vast oil and gas reserves has, in the last decade or so, been developing many new petrochemical complexes with their expansion into colossal polyolefin production capacities. The predictions are th...

This paper presents the results of study nickel-based coatings fabricated by cold gas spraying. In this study, compositions based on Ni, Ni–Cu, Ni–Zn, and Ni–Al2O3/TiC applied to low-alloyed steel bases were investigated. The composition, type powder (mechanical mix or mechanically alloying), thickness varied choose optimal characteristics for recovery, repair procedures, specific applications ...

Genetic algorithms (GAs) have proven to be a valuable method for solving a variety of hard combinatorial optimization problems. In this paper, we develop a pair of GAs to solve a layout problem in the fashion industry. Over the past years, a number of integer programming (IP) models have been constructed that are capable of solving small, real life layout cases in an acceptable amount of time. ...

a solid – liquid – gas, multiphase reactor, called inverse fluidized bed bioreactor (ifbbr) was used in this study for the treatment of starch industry wastewater of high organic content and acidic nature. mixed culture obtained from the sludge, taken from starch industry effluent treatment plant, was used as microorganisms. experiments were carried out in an inverse fluidized bed bioreacto...
