Opencast Mining

S.K. Chaulya, G.M. Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016 Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of

Unbanked American households hit record low numbers in 2021

20221025The number of American households that were unbanked last year dropped to its lowest level since 2009, a dip due in part to people opening accounts to receive financial assistance during the

Reverse osmosis

In 1977 Cape Coral, Florida became the first municipality in the United States to use the RO process on a large scale with an initial operating capacity of 11.35 million liters (3 million US gal) per day.By 1985, due to the rapid growth in population of Cape Coral, the city had the largest low-pressure reverse-osmosis plant in the world, capable of producing 56.8

Carbon capture and storage

Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO 2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia.Usually the CO 2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an

Ocean thermal energy conversion

Ocean Thermal Energy Conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.OTEC can operate with a very high capacity factor and so can operate in base load mode.. The denser cold water masses, formed by

Casemate

The term casemate wall is used in the archaeology of Israel/Palestine and the wider Near East, having the meaning of a double wall protecting a city or fortress, with transverse walls separating the space between the walls into chambers. These could be used as such, for storage or residential purposes, or could be filled with soil and rocks during siege in order to raise the

Definitions of coastal terms

This article gives an overview of terminology frequently used in the Coastal Wiki. The focus is on terms related to physical coastal processes and engineering.A complementary list of definitions related to the living environment is given in the article Definitions of marine ecological terms.. Many definitions in this glossary are derived from Mangor et al. 2017 and from the USACE

VTOL Drone

26.09.2022Advantages Disadvantages: VTOL vs Fixed-Wing. VTOL drones have several advantages over fixed-wing unmanned aircraft. They require much less space to launch and recover, as they do not need to use a runway. They are suited to applications such as inspection and monitoring where the drone must maintain a fixed position for a

Coal is made up of decomposed trees and plants that have been hardened by pressure and fire for millions of years. It is the most abundant fossil fuel

Earth shelter

Due to its density, compacted earth acts as thermal mass, meaning that it stores heat and releases it again slowly. Compacted soil is more of a conductor of heat than an insulator. Soil is stated as having an R-value of about 0.65-R per centimeter (0.08-R per 1 inch), or 0.25-R per 1 inch. Variations in R-value of soil may be attributed to different soil moisture

What is waterlogging? Effects, Causes, Prevention

An efficient drainage system should be provided in order to drain away from the stormwater and the excess irrigation water. A good drainage system consists of surface drains as well as subsurface drains. Improving the natural drainage of the area. To reduce percolation, it is necessary that water is not allowed to stand for a longer period.

Nuclear Waste Disposal

The types of radioactive nuclear waste that are suitable for each method along with the corresponding advantages and disadvantages will be discussed. Furthermore, conceptual methods of nuclear waste disposal will be studied to explore the feasibilities and/or constraints related to each idea.

Bioremediation Techniques for Polluted Environment:

2020127Environmental pollution has been rising in the past few decades due to increased anthropogenic activities. Bioremediation is an attractive and successful cleaning technique to remove toxic waste from polluted environment. Bioremediation is highly involved in degradation, eradication, immobilization, or detoxification diverse chemical

Pit latrine

Definitions. Depending on the region, the term pit latrine may be used to denote a toilet that has a squatting pan with a water seal or siphon (more accurately termed a pour-flush pit latrine – very common in South East Asia for example) or simply a hole in the ground without a water seal (also called a simple pit latrine) – the common type in most
