Window frame material has significant impact on the thermal performance of the window. Moreover, with sustainable design becoming a necessity, window frame materials need to have higher levels of environmental performance to be considered sustainable. As a result, a holistic performance metric is needed to assess window frame material. Three similar frames were considered, manufactured from alu...

In order to realize the fault diagnosis of the polyvinyl chloride (PVC) polymerization kettle reactor, a rough set (RS)–probabilistic neural networks (PNN) fault diagnosis strategy is proposed. Firstly, through analysing the technique of the PVC polymerization reactor, the mapping between the polymerization process data and the fault modes is established. Then, the rough set theory is used to t...

The objective of this study was to evaluate the influence different packaging on storage milk candy in tablets by means moisture, ash, lipid, protein, colour and texture profile analysis. were used: Expanded polystyrene wrapped with polyvinyl chloride film (PVC), polypropylene (PP) low-density polyethylene (PEBD) bags. experiment conducted a completely randomised design, evaluations carried out...

OBJECTIVES To investigate types of cancer caused by occupational exposure to vinyl chloride monomer (VCM) and the temporal mortality trends of these cancers in workers from polyvinyl chloride (PVC) manufacturing factories in Taiwan, with follow-up of the cohort extended by 15 years, from 1980 to 2007. Methods A retrospective cohort study of workers from six PVC factories in Taiwan was conducted...

Scanning electron microscopy revealed that the rpoS-deficient cells of E. coli K-12 BW25113 (ΔrpoS) increased the number of flagella on the cell surfaces. However, the quantitative analysis of cell colonization showed that the increased number of flagella on ΔrpoS cell surfaces did not cause the enhancement of cell colonization on the surfaces of polyvinyl chloride (PVC), polypropylene (PP) and...

Steam disinfection is a trusted method of decontamination and leave no residues, but yet has not been commonly applied for hospitals environment decontamination, hence we aimed to evaluate whether steam mop an effective device against pathogens on natural contaminated hospital floors (polyvinyl chloride, PVC) artificially (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Acineto...

The objective of this research was to study phenol degradation in anaerobic fluidized bed reactors (AFBR) packed with polymeric particulate supports (polystyrene PS, polyethylene terephthalate – PET, and polyvinyl chloride PVC). The reactors were operated with a hydraulic retention time (HRT) of 24 h. The influent phenol concentration in the AFBR varied from 100 to 400 mg L, resulting in phenol...

BACKGROUND Stylets are the most frequently used devices for tracheal intubation, but can be a source of postoperative pharyngeal pain or hoarseness. In this study, we evaluated extraction forces between polyvinyl chloride (PVC) and stannum (Sn) stylets with various lubricants. FINDINGS Using a manikin, we compared extraction forces between PVC and Sn stylets under four different conditions: w...

This paper provides a methodology for the structural integrity assessment of tubular beams containing U-notches, and particularises analysis to case cantilever through thickness U-notches. The is based on combined use Failure Assessment Diagrams Theory Critical Distances, with BS7910 as reference fracture document. results, obtained in Al6060 PVC (Polyvinyl chloride) beams, demonstrates that pr...
