Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas–metal arc welding using p
coli strains overexpressing the c-di-GMP-hydrolyzing phosphodiesterases, PdeC or Dos, contain more glycogen22. However, the mechanism by which this regulation occurs is unknown. Indeed, in contrast to the defined role of cAMP in the regulation of glycogen breakdown in humans, there is a big ...
The rise of the highly lethal severe acute respiratory syndrome-2 (SARS-2) as corona virus 2019 (COVID-19) reminded us of the history of other pandemics that happened in the last century (Spanish flu) and stayed in the current century, which include Severe-Acute-Respiratory-Syndrome (SARS)...
With the development of pharmaceuticals and the high pursuit of efficacy, the medical community has conducted further development and research on the enhancement of the absorption efficiency of active ingredients in natural medicines through the application of NDDS technology, which has resulted in notable...
Quartz Arenite Jodhpur sandstone Angular to subroundedMaximum: 640 μm, Minimum: 11 μmAverage: 234 μm Silica-cemented Well sorted Marginal marine environment The X-ray diffraction (XRD) analysis of the sandstone suggested the presence of quartz as the dominant mineral phase. In addition to qu...
1. Identify the Options: - Option A: Glass - Option B: Water gas - Option C: CNG (Compressed Natural Gas) - Option D: Plaster of Paris 2. Analyze Each Option: - Option A: Glass: Glass is primarily made of silica (SiO2) and may contain other components, but it is generally conside...
silica sand in window glass, What is minerals and its types? Minerals are classified into two types:Metallic and non-metallic. Metallic Minerals: They are further sub-divided into ferrous and non-ferrous. Ferrous minerals: They contain iron. Examples are iron ore, manganese ore, chromite, pyrit...
Geomorphologically, the Namibian and southernmost Angolan KC components are located within the watershed of the Kunene River, which created a rugged topography and excellent bedrock exposure. In contrast, north of the town of Oncócua, the KC forms part of the Huila Plateau – a flattened surface...
We introduce the refractiveindex.info database, a comprehensive open-source repository containing optical constants for a wide array of materials, and describe in detail the underlying dataset. This collection, derived from a meticulous compilation of data sourced from peer-reviewed publications, manufact...
Concrete has been one of the main materials that are used in almost all structures. The concrete industry causes some environmental problems such as global warming, natural resource depletion, air pollution, and waste. Cement, which is the major component of concrete, is a main producer of CO2...
