Abstract

Objective: To investigate occupational hazards in waste incineration power generation enterprises. Methods: From May 2016 to September 2018, four garbage incineration power generation enterprises in different regions and scales were selected as the survey objects. Investigated and analyzed the types of occupational hazards, workplace distribution and occupational disease prevention facilities and the concentration (intensity) of major types of work and workplace occupational hazards were also improved Line detection and analysis. Results: Silica dust could be seen in slag tank, slag sorting and crusher operation position. The concentration of silica dust in each workplace fluctuates within 0.3-1.1 mg/m(3). Both the concentration of silica dust in the workplace and the time weighted average allowable concentration (C-TWA) of dust exposure of dust exposed workers were detected, but none of them exceeds the requirements of the national occupational exposure limit. Carbon monoxide, ammonia, nitrogen dioxide, hydrogen sulfide, non methane total hydrocarbon, formaldehyde, hydrogen fluoride, hydrogen cyanide, hydrochloric acid, sodium hydroxide and ozone were detected, but all meet the requirements of national occupational exposure li...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
