BACKGROUND Significant numbers of people are exposed to tetrachloroethylene (perchloroethylene, PCE) every year, including workers in the dry cleaning industry. Adverse health effects have been associated with PCE exposure. However, investigations of possible cumulative cytogenetic damage resulting from PCE exposure are lacking. METHODS Eighteen dry cleaning workers and 18 laundry workers (un...

The paper describes the electrical plant response to mechanical stimulation monitored with the help of conducting polymers deposited on cotton fabric. Cotton fabric was coated with conducting polymers, polyaniline or polypyrrole, in situ during the oxidation of respective monomers in aqueous medium. Thus, modified fabrics were again coated with polypyrrole or polyaniline, respectively, in order...

Newfangled vinylsulfone (VS) based fiberreactive dyes were synthesized and applied to mill desized, bleached and mercerized textile fabric (100% cotton). Padthermosol dyeing method was utilized due to less hazardous environmental affects and high dye fixation to optimize dyeing quality parameters i.e. salt concentration, pH, dyeing time and dyeing temperature. The pretreated and dyed cotton fab...

Laser removal of particles from solid surfaces was investigated both theoretically and experimentally. A cleaning model was established for laser-induced removal of particles from solid surfaces by taking Van der Waals force, capillary force and cleaning force into account. Laser cleaning forces are induced by fast thermal expansion of particles and/or solid surfaces irradiated by laser for dry...

In view of the poor effectiveness existing potato cleaning methods in China and reflecting findings a research analysis basic sizes types impurities on tubers, gradient method for based multi-step dry-cleaning wet operation was proposed. The mainly consists cleaning. stage, which combines vibration brushing, could effectively remove such as residual rhizomes, peeled skin, large pieces soil crus...

Let us stipulate at the outset that “omission” refers to any action or event that doesn’t occur. In contrast, one might use “omission” to denote exclusively intentional failures (my refraining from picking up the dry cleaning), exclusively agent-involving failures (the gardener’s failure to water the plant), or failures with an explicitly normative dimension (as in Billy not following through o...
