Introduction: Since the removal of caries in Atraumatic restorative treatment (ART) is performed with hand excavation, its survival would increase if more bacteria could be inhibited under restoration. The use antibacterial agents such as Chlorhexidine gluconate (CHX) was found to hinder growth restorations, reducing risk recurrent caries. Objective: Evaluate effectiveness CHX a cavity disinfec...

This study focuses on the investigation of cavitating flow around benchmark INSEAN E779A model propeller with main aim further improving computational efficiency tip vortex cavitation (TVC) modelling by using a commercial CFD solver. Also, effects various key parameters including, numerical modelling, grid size, timestep, water quality and boundary layer resolution, TVC formation its extension ...

Studies were undertaken to investigate the effect of different modified atmospheric packaging (MAP) gaseous combinations on Campylobacter and the natural microflora on poultry fillets. Skinless chicken fillets were stored in gaseous mixtures of 10%, 30%, 50%, 70% and 90% CO2 balanced with N2, 80:20% O2:N2 and 40:30:30% CO2:O2:N2 and control conditions (air) at 2 °C. Samples were analysed period...

AIMS To examine the effect of subatmospheric steam treatment on total viable counts (TVCs) on bovine hide and on the quality of derived leather. METHODS AND RESULTS Pieces of bovine hide were heated to 75 degrees C (+/-2 degrees C) (n = 3) or 80 degrees C (+/-2 degrees C) (n = 3) for periods of 1, 10 or 20 s by the application of steam at subatmospheric pressure in a laboratory scale apparatu...

The conventional chorioallantoic membrane (CAM) phenotype assay was conducted using 11-day-old embryonatic eggs of white Leghorn strains, each inoculated with 0.2 ml of subgroup A Rous sarcoma virus (RSV) and subgroup C RSV separately containing 10(3)pfu ml(-1). Eggs were further incubated for hatching. Harvesting of CAMs for counting of pocks and monitoring chicks for liver tumour (LT) mortali...

Background: Melanomas arise from multipotent neural crest derivative, the melanocytes. At the tumor-stroma interphase, melanoma cells show organized neural differentiation forming tumor-vascular complexes. The present study explores the sequence of neurogenesis from aurophilic radial glial like cells in relation to angiogenesis, utilizing the tumor-vascular-complex (TVC) as a 3D model. Methods:...

The processes underlying motion-induced blindness (MIB) are widely debated. Ultimately, however, they must reduce to a sensitivity drop and/or to an upward shift of the decision criterion. The first possibility was tested by assessing the detection threshold for a contrast (or luminance) increment applied to the MIB target under its visible and suppressed phases. This was performed over a whole...
