Thousands of workers are employed in textile industries under different job categories including dyeing, printing, finishing, cutting, weaving and spinning. The textile industry workers are exposed to a number of chemicals including dyes, solvents, optical brighteners, finishing agents and numerous types of natural and synthetic fibre dusts which affect their health. In this paper an attempt ha...
The aim of this study is to develop methodologies suitable for conducting multiple organic solvent exposure assessments for workers in the plastic material printing industries. By reviewing the existing sampling and analytical methods for the seven organic solvents used in the industry (including isopropyl alcohol, 2-butanone, ethyl acetate, methyl isobutyl ketone, toluene, n-butyl acetate, and...
In Rajasthan 21,000 workers are engaged in hand processing textile industries (process gray/raw cotton cloth). They are exposed to hazards of the textile industries besides the harsh conditions of the desert which contributes to adverse effects on their health. To explore the occupational health problems of the desert textile workers and their association with nutrition and environmental factor...
Costs for workers’ compensation benefits in California have increased sharply in recent years, following periods of decline and stability. California was already one of the most expensive states for total costs per injured worker and for a number of types of testing and treatment in the midto late 1990s. For example, a series of multi-state studies revealed that California has the second highes...
Background: Today, the prevention of work-related musculoskeletal disorders (MSDs) is considered as a vital issue and one of the highest national priorities. This study was conducted with the aim of evaluating occupational postures and the prevalence of MSDs among porcelain industry workers of the city of Rasht, Iran. Materials and Methods: This cross-sectional study was done in 2015 on 66 w...

3D Printing In article number 2208365, Rihan Hai, Cheng Sun, and co-workers report a method for printing the key optical optomechanical components of miniature accommodating microscope in 50 min less than $4. Synergizing built-in voice-coil-motor compliant optomechanics facilitates focus stacking functionality extending imaging depth. enables digitized component manufacturing, part-count reduct...
Volumetric 3D Printing In volumetric printing, the whole object is developed simultaneously (i.e., volume-at-once) by means of light-induced crosslinking a (rotating) liquid resin, as reported Sandra Van Vlierberghe and co-workers in article number 2210136. The 3D-structure illustrated image based on chemical network structure thiol–ene crosslinked poly(caprolactone) (PCL) network, which can be...
printing and packaging industries make three phases of solid, liquid and gaseous contaminants which can cause very dangerous problems. the presence of alcohols, inks, and cleaners can result in massive range of industrial pollutants. always respiratory problems, fatigue, dizziness, weakness, abnormal behavior, memory impairment, insomnia, loss of appetite, and impaired vision and hearing and ca...
Printing and Annealing In article number 2207447, Weiwei Li, Manzhang Xu, Jiuwei Gao, Xuewen Wang, Wei Huang, co-workers demonstrate how MoS2 patterns can be directly synthesized on polymer substrates using a printing-and-annealing strategy. These patterned layers exhibit exceptional mechanical durability chemical stability, which contribute to the realization of flexible sensing electronic dev...
