background: personal protection equipments (ppes) should be easily accessible to decrease contact with infecting factors and also should be used purposefully to effectively keep the health care personnel in a safe distance from the patient blood and body fluid which can easily infect the operating rooms personnel. this study aimed to find the operating rooms' personnel compliance with standards...

[1] A cloud masking algorithm based on the spatial variability of reflectances at the top of the atmosphere in visible wavelengths was developed for the retrieval of aerosol properties by MODIS. It is shown that the spatial pattern of cloud reflectance as observed from space, is very different from that of aerosols. Clouds show a very high spatial variability in the scale of hundred meters to f...

abstract this study aims to examine the use of religion heritage and application of the prophet job’s character mask. one of the important masks that have been used by contemporary poets is the prophet’s masks, especially the job of which the story exists in the quran. this character is a symbol of patience. darvish and sayyab are the most important poets who used the mask of this character.  e...

The effects on the inner surface temperatures of the upper and lower eyelids of four commercial heat therapies were compared for an individual with recalcitrant meibomian gland dysfunction. Three therapies (Bruder mask, Blephasteam, and MiBoFlo) involved the application of heat to the external lid surface, and the fourth (LipiFlow) applied heat to the internal lid surface. Only LipiFlow was eff...

One of the important evidence in a crime scene that is normally overlooked but very important evidence is shoe print as the criminal is normally unaware of the mask for this. In this paper we use image processing technique to process reference shoe images to make it index-able for a search from the database the shoe print impressions available in the commercial market. This is achieved first by...

Illusory continuity is known as a psychoacoustical phenomenon in hearing; i.e. an intermittent pure tone may be perceived as if it was continuous, when it is padded with enough large white noise. There are many researches related to this issue in monaural listening. It is said that such illusory continuity is observed when there is no evidence of discontinuity and level of the white noise is la...

BACKGROUND Studies of visual backward masking have frequently revealed an elevated masking threshold in schizophrenia. This finding has frequently been interpreted as indicating a low-level visual deficit. However, more recent models suggest that masking may also involve late and higher-level integrative processes, while leaving intact early bottom-up visual processing. OBJECTIVE To test the ...

This paper presents a hybrid watermarking technique which mixes additive and multiplicative watermark embedding with emphasis on its robustness versus the imperceptibility of the watermark. The embedding is performed in six wavelet sub-bands using independently three embedding equations and two parameters to modulate the embedding strength for multiplicative and additive embedding. The watermar...

Three tachistoscopic tasks were employed to assess whether survivors of severe closed head injury (CHI) exhibit a disturbance of information processing within peripheral and/or central visual pathways. Twelve survivors of severe CHI and 12 individually matched control subjects completed a recognition threshold (no mask) task, a monoptic, forward masking by visual noise task (to assess processin...
