The forensic application of barefoot morphology involves the study of the physical features of feet and the impressions they make. This type of examination is used in cases when either an impression has been made at the scene of a crime or when the wearer of a shoe needs to be determined. However rare the application, in instances where it is needed to answer a question in a criminal case, bare...

The dynamics of a compound vesicle (a lipid bilayer membrane enclosing a fluid with a suspended particle) in shear flow is investigated by using both numerical simulations and theoretical analysis. We find that the nonlinear hydrodynamic interaction between the inclusion and the confining membrane gives rise to new features of the vesicle dynamics: The transition from tank treading to tumbling ...

conclusions within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. however, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions. background dental impressions often carry microorganisms that may cause cross-infection from patients to d...

introdouction: infection control procedures are essential fordentists. oral and dental impressions can act as carriers of contaminants that can increase the risk of infections while being transferred from the laboratory to the dental office. therefore, the aim of this study was to evaluate the knowledge and practice of dentists regarding disinfection of impressions sent to the laboratory. mater...

objectives: this study aimed to assess the effect of storage time and temperature on dimensional stability of impressions made with cavex outline zinc oxide impression paste. materials and methods: a round stainless steel mold with five grooves (three horizontal and two vertical) was used in this in-vitro experimental study. cavex outline impression paste was prepared according to the manufactu...

3 The purpose of this study was to quantify how vegetation influences the flow and sediment processes 4 relevant for the design and management of environmental compound channels. Therefore, we conducted a 5 two-year field investigation in a cohesive two-stage channel, focusing on the flow resistance and net 6 deposition in five sub-reaches with different floodplain vegetation conditions. In the...

In areas that are occasionally inundated by floods, it is essential to know the quantity and density of vegetation that can be allowed while avoiding flooding beyond the intended floodplains. An unsteady flow model was developed for a channel with vegetated floodplains, to take into account the retention effects of the vegetated areas on flood wave conveyance. A one-dimensional (1D) unsteady fl...

Impression procedure forms the basis of a successful Removable Partial Denture however, in distal extension bases the residual ridge must be recorded in functional form and the remaining natural teeth in an anatomic form. Zinc oxide eugenol impression paste is a material of choice for functional impression whilst irreversible hydrocolloid is suitable for an anatomic impression. Therefore two-pa...
