The tropics of Malaysia have plenty to offer when it comes to its biodiversity. In the animal kingdom, snakes play a crucial role and form a large component in the ecosystem, with human envenomation being a fairly common problem. From 1965 to 1971, there were 5203 reported cases of venomous snake bites throughout Malaysia, 18 of which being fatal cases. Symptomatology varies, ranging from mild local symptoms on one end of the spectrum to life threatening systemic manifestation on the other end. ...

The negatively charged coordination groups on the structure of these biomolecules, which is the main components of extracellular polymeric substances (EPS), have good adsorption efficiency for heavy metals. In this paper, EPS form Proteiniphilum acetatigenes PSB-W which was extracted by EDTA method, and the effects of pH, EPS dosage, adsorption time and initial metal concentration on the adsorption regularity of Cu2 and Pb2 ions on EPS structure were studied respectively, as well as the adsorp...

At present, a cost-effective selection of parameters for Chemical Oxygen Demand (COD) and turbidity reduction is of great importance for wastewater treatment. Like most water treatment processes, the coagulation treatment process may sound simple but is considered as an important method for wastewater treatment as it helps to remove COD and other pollutants found in wastewater. Poly aluminum chloride (PAC) with Poly ammonia (PA) coagulants was used to study the performance of the coagulation pro...

The use of water resources is ineffective although Turkey has insufficient freshwater resources. Dry farming is practiced in a large part of agricultural land. This land due to insufficient precipitation throughout the country is left to fallow once in two years. Agricultural drought is becoming a severe challenge for agriculture and food security, and it may also impact the wealth of farmers by agriculture income. So, it causes widespread concern among the rural population. There is a close rel...

Urban ecological management in the context of big data space is an objective need for urban development. The ecological environment of a city is a comprehensive group of various ecological factors and ecological relationships that people in urban areas rely on for survival, development, and evolution. Geographic information is performed on the effective management of system technical means. Predictive decision-making and analysis can be made by processing urban spatial data, urban resources, and...

The energy resources diversification has been increased with the energy crisis, in particular, the renewable energies and optimal management have become essential in the context of sustainable development. The conventional auto-thermal gasification processes burn part of the carbonaceous compound in order to supply the energy necessary to enhance gasification reactions. This energy could be provided as well by a nuclear reactor of IV generation. The nuclear heat is transferred from the VHTR to a...

During the last three decades, the electrocoagulation (EC) process has known an exemplary renaissance in the field of water and wastewater treatment. Sev-eral researchers focused on applying this electrochemical technology in re-moving diverse pollutants such as pathogens. During EC method, the coagulant is furnished via solubilizing sacrificial electrodes upon an applied electric field. The easiness of the technology and the side phenomena involving the genera ...

In this study, a certain zone of Libra oil field of the pre-salt region was se-lected to be analyzed for didactic purposes in order to simulate AVO re-sponses. The region was modeled using seismic data, setting up a typical oil system with source rock (shale), reservoir rock (sandstone), and seal rock (salt). Thus, a set of parameters such as seismic wave velocity, density and Poisson’s ratio for the studied zone w ...

Reforestation management goes through the knowledge of the tired out evolution after a forestry rest. The aim of this study was to assess biodi-versity concerning Terminalia superba Engl. & Diels and its undergrowth, and then quantify sequestered carbon stocks to appreciate the impact of reforestation on forest recovery and the enhancement of carbon stocks. The study was conducted at Bilala artificial forest in southeastern Re ...
