Description
Oceanography and Marine Biology: An Annual Review remains one of the most cited sources in marine science and oceanography. The ever-increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative refereed reviews summarizing and synthesizing the results of recent research. For more than 50 years, OMBAR has been an...

Description
Dendrimers represent a distinct class of polymers—highly branched and uniform, with a relatively small size when compared to their mass. They are composed of the core, from which branched polymeric dendrons diverge and they are end‐capped with selected terminal groups. Recently, dendrimers have attracted considerable attention from medicinal chemists, mostly due to their well‐defined and easy‐to‐modify structure. This chapter aims to compile...

With the growing participation of natural gas (NG) in power generation industry, a global worry about the effects of chemical composition changes on the behavior of gas turbines. A comparison of fossil fuels consumption used in power industry is shown in Figure 1 [1]. This figure represents a projection for the years 2003-2013 according to what is expected by the Mexican electric industry. - from Introduction

In this chapter, four natural polyhydroxy alcohols (polyols), including xylitol, sorbitol, adonitol, and erythritol were selected as the subject of study on phase change materials for thermal energy storage application. The thermodynamic study on these polyols was performed by adiabatic calorimetry (AC), differential scanning calorimetry (DSC), and thermogravimetric analysis (TG). The heat capacities of these polyols were measured in the temperature...

The electric field of a charged particle passing through or near an optical fiber induces a transient charges and currents in the fibrer medium (1; 2). These charges and current radiates electromagnetic waves, both outside the fiber (free light) and inside (guided light). This chapter is devoted to the guided light, which will be referred to as PIGL, for Particle Induced Guided Light.
If the fiber radius is large enough and the particle passes trough...

Autophagy is an evolutionarily conserved intracellular system that selectively eliminates protein aggregates, damaged organelles, and other cellular debris. It is a self-cleaning process critical for cell homeostasis in conditions of energy stress. Autophagy has been until now relatively overlooked in skeletal muscle, but recent data highlight its vital role in this tissue in response to several stress conditions. The most recognized sensors for autophagy...

Anomalous Transient Photocurrent
In summary, we analysed the anomalous transient photocurrent in the BDTDA photocells
based on a double-layer model. Resuts indicate that the dielectric property of organic
materials will strongly influence the anomalous behaviour. For instance, a large dielectric
constant will induce a larger anomalous photocurrent. This was confirmed in equivalent
devices, such as ITO/PVDF or polystyrene/ZnPc:C60/Al, in which the...

This study explored the best operating conditions for a novel electrocoagulation (EC) reactor with the rotating anode for textile wastewater treatment. The influence of operating parameters like interelectrode distance (IED), current density (CD), temperature, pH, operating time (RT) and rotation speed on the removal efficiency of the contaminant was studied. A comparative study was done using conventional model with static electrodes in two phases...

The predatory exploitation techniques used for the supply of protein resources have been systematically causing the decrease in seafood. The solution was sought in the form of marine farms, for the purpose of production of fish and seafood. Brazil created an incentive production of seafood in order to increase seafood production. In 1998, the state governments joined the project, encouraging the creation of marine farms without an assessment of the...

Description
Natural gas (NG) is an environment-friendly energy source. NG is of gas state in the environmental condition and it is liquefied to LNG at temperature of about −162°C for transportation and storage. Electric energy of 292–958 kWh is consumed when one ton of LNG is produced. Before being used, LNG must be regasified to NG again at the receiving site, and this process will release a great deal of energy, which is called cold energy. It’s very...

Assessment of the Vulnerability Potential for an Unconfined Aquifer in Konya Province, Turkey
An extensive sampling and in situ conductivity measurements of a large number of water
wells have been carried out in the study area. Based on this data, the elemental
concentration contour maps showed that the solid waste site has adversely influenced the
ground water quality severely, contaminating the nearby zone. The contamination will get
worse unless...

Climate changes have already been noted all over the world. The reasons for these changes are complex and there are disagreements in the scientific community about the causes. Some scientists believe that changes are part of natural variability while others point to human activity as the cause of increasing atmospheric concentrations of green house gases (GHGs) and the key driver of climate changes. Many scientific studies come to the conclusion that...

The challenge of agricultural land depletion as a result of the pressure driven by the ever-growing population has brought about a renewed focus on the need for sustainable practices in agricultural production. Biochar is the solid carbonaceous product obtained when plant and/or animal biomass is subjected to pyrolysis. This chapter reviews the properties of biochar and its impacts when incorporated into the soil. Relative to its original organic...

The aim of this work is to design newer material for food packaging applications and to valorize the Moroccan marine wastes using chitosan (CS) prepared from exoskeletons of shrimps. Biodegradable and uniform nanocomposite films developed from sodium bentonite nanoparticles dispersed in chitosan matrix were carefully studied. The montmorillonite is used as nanofiller, and aqueous acetic acid solution is employed as a medium for dissolving and dispersing...

Heavy metals have always been defined as elements with a density higher than 5 g/cm3. They are regarded as serious wastewater contaminants with detrimental effect to human and environment. Their removal from wastewater poses a serious challenge as they require cost-effective reagent and treatment technique. About 200 mL solution of acid mine drainage (AMD) collected from the Western decant in Krugersdorp, South Africa was poured into five 500 mL glass...

This study is aimed at investigating the potentials of oil palm wastes as an alternative to fossil fuels (coal) for domestic heat generation via briquettes (solid fuels) production. In this study oil palm wastes such as empty fruit bunches (EFB), mesocarp fiber (MF) and palm kernel shell (PKS) were pyrolyzed at temperatures of 400°C for 120 min and a heating rate of 10°C min−1. The biochar and bio-oil obtained were blended in the ratio of 60:40...
