Modeling and Optimization of Adsorption of Heavy Metal Ions onto Local Activated Carbon

Heavy metal ions such as copper, iron, nickel, lead, etc. in the environment are of major concern due to their toxicity to many life forms. Unlike organic pollutants, which are susceptible to biological degradation, metal ions do not degrade into any harmless end products (Mohammadiet al., 2010) and tend to accumulate causing several diseases and …

Zoning Model on Conservation in the Ecosystem Islands Southeast Aru

Ecosystem conservation was an effort to protect, to preserve, and to utilize the ecosystem function as the supporting habitat for the living of fish resources either for recent or future days (Adams et al, 2004). Indeed, ecosystem conservation was realized through the protection of habitat and population of the fish, the research and development, the …

Vescular Arbuscular Mycorrhiza Diversity and Morphotypes, from Different Land Use of the Serengeti National Park, Tanzania

Vesicular arbuscular mycorrhizas (VAM) are extremely successful fungi that form mutualistic symbioses with about two thirds of all plant species (Smith & Read 1997). VAM fungi are of great ecological importance since arbuscular mycorrhizae are the most widespread plant symbiosis that often improves plant productivity (Fedderman et al., 2010). The main advantage of mycorrhizae to …

A Hot-topic based Distribution and Notification of Events in Pub/Sub Mobile Brokers.

The future Internet of Things (IoT) demands a closer breach between fixed and mobile envi- ronments in the content plane; so, even if devices are loose coupled the information they produce should be available from end-to-end. In this context, the Publish/Subscribe (Pub/Sub) paradigm [1] has emerged as an attractive communication model for exchanging content be- …

Production, Proximate and Sensory Evaluation of Rhynchophorus Phoenicis (F) Larva Paste

Insects are used as human food in many parts of the world. In some developing countries, it is viewed with aversion but elsewhere, it is seen as a wise utilization of natural resources because insects form a greater part of the phylum arthropods which dominates the animal kingdom. The larva of the beetle Rhynochophorus phoenicis …

Effect of Freezing on Some Plant Toxins and Micronutrients in the Leaves of Amaranthus Cruentus

Amaranthus cruentus is an important leafy vegetable, grown throughout the temperate and tropical regions of the world. It is an herbaceous annual leafy vegetable that can be produced for fresh market in 4 – 6 weeks after planting (Schippers, 2000). The vegetable can be produced all the year round depending on the availability of water. …

Evaluation of Smart Grid Simulation System with Power Stabilization by EV

Recently, the scarcity of natural resources and rapid increases in energy demands have been raised as worldwide problems; thus, it has become necessary to promote renewable energy generation as a means of energy conservation. As a result, power plants of renewable energies draw attentions such as solar power, wind power, geothermal power, and so on. …

Green Communications and Networking

Global warming and climate change have been a growing worldwide concern. Six sources, i.e., transportation, power, buildings, industry, agriculture and forestry, and land use, have been identified as major contributors to the rise of global carbon dioxide (CO2). The mobile industry is seen as a potential enabler to reduce greenhouse gases contributed by these six …

Macrozoobenthos Soft Soils of the Far Eastern Marine Biosphere Reserve

Composition and distribution of the benthic fauna of the soft soils of the Far Eastern Marine Biosphere State Nature Reserve are still not sufficiently explored. In 1963, the hydrobiological monitoring in this area were conducted only in waters of the bays Sivuch’ya and Kalevala (Mikulich & Biryulina, 1970). Expedition of the Pacific Research Institute of …

Experimental Verification of Formulae for Natural Seiche Frequencies in a Two-layer Fluid with the Free Surface

A seiche is a standing wave in an enclosed or partially enclosed body of water (http://en.wikipedia.org/wiki/Seiche). Seiches generate significant horizontal and vertical velocities of water movements. It is unpleasant for ships and is essential for ecology. Both surface and internal seiches exist in water with stable density stratification. There are the explicit theoretical formulae for …
