The aim of this study was to prepare a novel dental restorative material (NDRM) and to understand its cell viability behavior. The hydroxyapatite (HA) nanopowder was synthesized using a wet chemical precipitation method using calcium hydroxide and orthophosphoric acid as precursors. The as-prepared HA nanopowder was annealed at different temperatures

Using the methane energy potential to produce electrical energy or as biofuel could reduce GHG emissions by up to 258 and 812%, respectively, and the cost
The daily based erosion model incorporates vegetation cover changes for estimating interception and evapotranspiration. Effective rain is estimated by subtracting interception from daily rain. The runoff fraction is based on the available daily storage of the effective hydrological depth. Soil moisture depends on daily rain, soil physical

Soil erosion by water is serious global problem. In Africa, about 5 Mg ha −1 of productive topsoil is lost to lakes and oceans each year. This study was conducted at the Kianjuki catchment in central Kenya to predict annual soil loss using the Revised Universal Soil Loss Equation (RUSLE Version 1.06) to determine the erosion hazard in the area
The TP concentration in the wetland is a matter of concern for wetland health as it has crossed the limit of hyper-eutrophication which is 100 μg L −1 (OECD, 2014). The WQI reflected the state of water quality of the wetland. The wetland''s high and severely deteriorated zones (21%) are closely associated with orchards and built-up areas.
Following Ismaiel et al. [] technique, each plant species had an endophytic fungus isolated.Plant materials (leaf and stem) were subjected to a process of surface sterilization that started with a thorough washing under running water for five minutes to remove dust and debris, followed by air drying, immersion in 70% ethanol for one minute,

A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to statewide government monopolies.
Herein, the maximum energy balance value, the ratio of energy to mass, and the kinetic constants μmax and K of anaerobic digestion of WAS were −33.44 kJ·day–1, −5.72 kJ·VS–1·day–1
Television. Television ( TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set, rather than the medium of transmission.
Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate
Hydrogels are compelling materials for emerging applications including soft robotics and autonomous sensing. Mechanical stability over an extensive range of environmental conditions and considerations of sustainability, both environmentally benign processing and end-of-life use, are enduring challenges. To make progress on these challenges, we
Polymeric ionogels are polymer networks swollen with ionic liquids (i.e., salts with low melting points). Ionogels are interesting due to their unique features such as nonvolatility, high thermal and electrochemical stability, excellent ionic conductivity, and nonflammability. These properties enable applications such as unconventional
Most of the mapping studies are however conducted at the regional (10 3 -10 5 km 2 ) and national (10 5 -10 6 km 2 ) levels (Malinga et al., 2015;Martínez-Harms & Balvanera, 2012) and with

Polymers based on 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) attract significant attention due to their large water absorption capacity when swollen in water. Poly(AMPS) (PAMPS) hydrogels are usually synthesized via free-radical cross-linking copolymerization of AMPS and a chemical cross-linker in aqueous solutions. Owing to

Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive (especially from intermittent power sources such as renewable electricity from wind power, tidal power and solar power) or when demand is low
- R&D offshoring to India has grown significantly since 2002 and is now a $5.83 billion industry, with software product development being the largest segment at $3.15 billion. - The top locations for R&D centers in India are Bangalore, NCR and Pune, which together account for about 80% of the 594 total centers.
