Desalination and water reuse technologies are critical for solving water problems. Unlocking water resources through the minimization of reverse osmosis (RO) concentrate volume offers sustainable opportunities to meet the challenge. A pellet softening lime intermediate concentrate chemical stabilization (ICCS) reactor and a conventional lime softening ICCS for the treatment of RO concentrate we...

References 595 CONTENTS Policies adopted to mitigate global warming will have implications for specific sectors, such as the coal industry, the oil and gas industry, electricity, manufacturing, transportation and households. A sectoral assessment helps to put the costs in perspective , to identify the potential losers, and the extent and location of the losses, as well as to identify the sector...

The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel combustion and land use change necessitates identification of strategies for mitigating the threat of the attendant global warming. Since the industrial revolution, global emissions of carbon (C) are estimated at 270F 30 Pg (Pg = petagram= 10 g = 1 billion ton) due to fossil fuel combustion and 136F 55 Pg due to...

This study analyzes the relationship between energy production from fossil fuels, low-carbon sources, and renewable sources inflation in Kazakhstan 2000 to 2021, using VAR method within framework of Taylor rule. Energy is categorized under two headings, namely fuels other sources. While examining inflation, interest rate GDP growth rate, which affect were also included model as control variable...

Perth will run out of available sustainable natural water resources by 2015 if nothing is done to slow usage rates, according to a Western Australian study [1]. Alternative water technology options need to be considered for the long-term guaranteed supply of water for agricultural, commercial, domestic and industrial purposes. Seawater is an alternative source of water for human consumption, be...

Radiocarbon samples taken over Mexico City and the surrounding region during the MILAGRO field campaign in March 2006 exhibited an unexpected distribution: (1) relatively few samples (23%) were below the North American free tropospheric background value (57±2‰) despite the fossil fuel emissions from one of the world’s most highly polluted environments; and (2) frequent enrichment well above the...

The growth of renewable energy actively takes part in decarbonizing the fossil-fuel-based system. It reduces carbon emissions, footprint, and greenhouse gas emissions increases clean energy. usage resources solves several problems, such as increasing temperature, waste. Every sector contributes to above-mentioned factors environment. One main reasons for this biodegradation climate change is re...

Also known as... ancient DNA. The New Shorter Oxford Dictionary offers the precise explanation of ‘ancient’ as ‘belonging or pertaining to the period before the fall of the Western Roman Empire in AD 476.’ DNA can be recovered from fossils much older than 1500 years, but the inevitable time-dependent decay of the DNA structure due to oxidation and hydrolysis makes retrieval increasingly difficu...

Over the last three decades, the fossil record of spiders has increased from being previously biased towards Tertiary ambers and a few dubious earlier records, to one which reveals a much greater diversity in the Mesozoic, with many of the modern families present in that era, and with clearer evidence of the evolutionary history of the group. We here record the history of palaeoarachnology and ...
