Abstract:
The use of an old fuel in a new form has progressed at a rapid space for the last couple of years, due to its several advantages. The fuel in question is natural gas and, its new form, is liquefied natural gas designated as LNG. LNG transported in cryogenic vessels offers several advantages over pipe line transport of natural gas when the gas consuming areas are far away from the gas producing areas. Moreover, LNG as an automobile fuel has also a definite edge over other fuel. However, the LNG age in India is of very recent origin and, only in January, 2004, the first LNG cargo had reached an

Civil Engineering is the study of planning, construction, and maintenance of physical structures such as bridges, buildings, and roads. These include sub-fields such as geotechnical, structures, transportation, hydraulics and environmental management. Civil engineers also study ways to manage natural and environmental resources used in construction projects Civil engineering can be used in eco-green environmental analysis. One example is in the planning and construction of green buildings, which are buildings that are designed and constructed in an environmentally friendly way. Civil engineeri

Background: Environmental issues and health problems related to global climate change are becoming increasingly serious. An effective eco-friendly strategy is required to reduce medical waste and greenhouse gas emissions caused by anesthesia in hospitals.Current Concepts: Inhalation anesthetics are very strong greenhouse gases in the order of desflurane, isoflurane, nitrous oxide, and sevoflurane. Anesthetics with high global warming potential and long atmospheric lifetimes should be used with caution. Only the minimum required dose of an anesthetic drug with a low persistence bioaccumulation

Activities of oil and gas exploration continuous to post serious challenges to the environment. Recognizing this, the current study examines the effect of eco-efficiency on the performance of oil and gas companies and the impact of firm size on the relationship. The sample includes listed oil and gas companies in Nigeria. The data utilized were extracted from the annual report data stream for period of ten years from 2011 to 2020. Multiple regression through ordinary least square was employed to analyse the data. The study shows a positive association between eco-efficiency and firm financial

Abstract Making a palatable complete feed formulation has a good effect on ruminant productivity, and eco-friendly feed is a solution step in sustainable livestock production. The aims of this study were to evaluate the quality of complete feed based on forage sorghum-Indigofera on the in-vitro of gas production and nutrient digestibility value. Three feed compositions consisting of forage silage of sorghum, Indigofera hay, and rice bran were mixed as SI feed and field grass (FG) as control. All the experimental feeds were replicated five times, then gas production and nutrient digestibility w

Abstract:
The upcoming autonomous vessel voyage is promising future in the maritime sector. However, so far, the contemporary route decision making technologies rely on human intervention. Therefore, this manuscript proposes the two newly developed speed algorithms: the modified fixed speed control and the wave feed forward speed control in the route decision making procedure for the autonomous vessels. These two algorithms can control the vessel’s speed without human intervention in eco-friendly and economic manner. The first algorithm is the wave feed forward speed control that can predict the speed c

Abstract:
As nitrogen is nonreactive and non-flammable, it can provide a quick and simple medium of cooling and environment protection. One disadvantage of nitrogen cooling is its lower heat transfer coefficient than water. Despite its lower cooling capacity, nitrogen cooling can produce cleaner products, thereby eliminating the need to wash the parts and dispose of the contaminated water. In this study, an innovative nitrogen cooling system was developed for an accelerated and eco-friendly cooling of metallic parts.

The use of refrigerants with a global warming potential (GWP) greater than 150 is banned in small and medium-sized refrigerators in accordance with the European F-Gas policy. Therefore, the suitability of retrofitting an existing refrigerator using a low GWP working fluid (R152a), as a replacement for the usual refrigerant (R134a) that is harmful to the environment, was investigated experimentally in this paper. In this study, close trend and similarities have been observed between the retrofit refrigerant (R152a) and the traditional refrigerant (R134a) in terms of their thermophysical propert

In recent years, lithium compounds have been seen as energy materials of great commercial value as the global energy industry develops. The use of lithium-ion batteries (LIBs) in electric vehicles (EVs) is driving the global demand for lithium resources. While many studies have shown that EVs have environmental benefits over internal combustion engine vehicles, the impact of battery production is still uncertain. We need to dramatically reduce greenhouse gas (GHG) emission from the LIBs manufacturing process and raw battery material production. Typically, lithium compounds have been produced f

Abstract:
The growing increase in greenhouse gases, especially carbon dioxide (CO2), by anthropogenic activities can be linked to extreme climate events, such as intensive droughts, floods, or hurricanes, and has led to several studies focused on reducing the concentration of this greenhouse gas in the atmosphere. Some technologies, such as carbon capture and storage (CCS), can potentially sequester billions of tons of CO2 per year. One of the promising methods is the use of carbon mineralization as a CCS methodology. For this approach, some minerals can be investigated, such as wollastonite, which can
