Intentionally looking bad at work is a type of impression management in which employees purposefully attempt to convey unfavorable impressions. Drawing on the employment experiences of 162 individuals, we documented five forms of such behavior: decreasing performance, not working to potential, withdrawal, displaying a bad attitude, and broadcasting limitations. Motives for managing poor impress...

A range of chemical techniques were utilised for the enhancement of footwear impressions deposited on a variety of fabric types of different colours with urine as a contaminant. A semi-automated stamping device was used to deliver test impressions at a set force to minimise the variability between impressions; multiple impressions were produced and enhanced by each reagent to determine the repe...

--Many watermarking methods for protecting the intellectual property right and authenticating multimedia data have been proposed in recent years. It is possible to guarantee the authenticity of data using readable and fragile watermarking. In this paper, we propose a visible watermarking technique using verifiable digital seal image that is based on the concept of fragile watermarking. Seal ima...

Since the introduction of mechanical seals in nuclear boiling water reactor (BWR) feed pumps operating with high drive ratings, keeping mechanical seal reliability high became a challenge. A problem also encountered in fossil feed pump applications using similar electrically low conductive feed water, referred to as Combined Water Treated (CWT) feed water operation. After a short number of oper...

The heat-seal strength and failure modes of laminated films with Linear Low Density Polyethylene (LLDPE) and Low Density Polyethylene (LDPE) as the sealant materials were investigated. Heat-seal strength increases with platen temperature for all samples. The maximum achievable heat-seal strength for laminated film using LDPE and LLDPE as sealant material is 0.598 N/mm and 4.02 N/mm, respectivel...

Purpose: The objective of the present study was to evaluate the effect of ultraviolet ray combined with immersion method on the disinfection of silicone impression materials. Methods: Forty eight silicone impressions were rinsed by flushing water and then completely dried. Impressions were randomly divided into A and B groups (n=24). In group A, serum sample with positive hepatitis B virus was ...

abstract statement of the problem: dental prosthesis is usually made indirectly; therefore dimensional stability of the impression material is very important. every few years, new impression materials with different manufacturers’ claims regarding their better properties are introduced to the dental markets which require more research to evaluate their true dimensional changes. objectives: the ...

Enhancement of footwear impressions, using ninhydrin or ninhydrin analogues is not considered common practice and such techniques are generally used to target amino acids present in fingermarks where the reaction gives rise to colour and possibly fluorescence. Ninhydrin and two of its analogues were used for the enhancement of footwear impressions in blood on various types, colours and porositi...
