Water-miscible metalworking fluids (MWFs), commonly used in metal forming operations, are lubricants that must be safe for direct human contact. The proper selection of materials in a new metalworking fluid, while being environmentally friendly, helps to

Organizational Fairness Perceptions, Employee Representation, and Firm Performance
ABSTRACT From a theoretical perspective, employees' fairness perceptions play a vital role in explaining the effect of employee representation on individual and firm‐level outcomes. However, the fairness argument has not been scrutinized in empirical studies yet. Using German longitudinal linked employer‐employee data, we show that particularly central

Purification of semi-synthetic metalworking fluids by microfiltration
Since the early 2000s, industries have faced rising costs to acquire, manage, and dispose of metalworking fluids, as well as increased concern about pathogenic bacteria growing in metalworking processes.

An analysis method using simple instrumentation was developed to investigate isothiazolinones in cosmetic and household products in patch test investigations. Analysis showed that concentrations of benzisothiazolinone can be several orders of magnitude higher than those of chloromethylisothiazolinone/methylisothiazolinone in products to which skin ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere. Results

Early immunopathological events in acute model of mycobacterial hypersensitivity pneumonitis in mice
Prolonged exposure to antigens of non-tuberculous mycobacteria species colonizing industrial metalworking fluid (MWF), particularly Mycobacterium immunogenum (MI), has been implicated in chronic forms of hypersensitivity pneumonitis (HP) in machinists ...

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst
Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...
