Sophisticated three-dimensional animation and video compositing software enables the creation of complex multimedia instructional movies. However, if the design of such presentations does not take account of cognitive load and multimedia theories, then their effectiveness as learning aids will be compromised. We investigated the use of animated images versus still images by creating two version...

Lack of drinking water is a global problem and especially in overdeveloped countries. this why many research laboratories are focused on solving problem. one the simplest, economical, environmental methods use conventional solar stills. Sand from city Illizi southern Algeria was used our to see how it affected distillation. So, with dimension (0.50 x 0.50 m), two identical stills were evaluated...

Background: Crohn’s disease is an inflammatory bowel disease that can affect any part of the gastrointestinal (GI) tract including the mouth. Bowel symptoms are predominant. Oral involvement may precede the GI symptoms. This case report presents a patient affected by Crohn’s disease with oral onset. Case presentation: We present a 30-year-old pregnant woman complaining of chronic, ...

the association of hla and disease varies in different populations. we have . studied the association of hla class i in iranian psoriatic patients, in order to compare this association with other reports. fifty-one iranian patients with psoriasis were hla typed. the frequency of hla antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and provocat...

Expressions for water and glass temperatures, hourly yield and instantaneous efficiency for both passive and active solar distillation systems have been derived. The analysis is based on the basic energy balance for both the systems. A computer model has been developed to predict the performance of the stills based on both the inner and the outer glass temperatures of the solar stills. In the p...

Systems for still-to-video face recognition (FR) seek to detect the presence of target individuals based on reference facial still images or mug-shots. These systems encounter several challenges in video surveillance applications due to variations in capture conditions (e.g., pose, scale, illumination, blur and expression) and to camera inter-operability. Beyond these issues, few reference stil...

Nowadays freshwater needs were covered by fossil fuel-based desalination systems in many areas over the world. However, fuels’ excessive burning results rapid depletion and pollution of local environment as well threat to life sustainability. Therefore, through last few decades scientific community focused on relying solar energy seawater a clean alternative. Stepped stills, which convert requi...

The association of HLA and disease varies in different populations. We have . studied the association of HLA class I in Iranian psoriatic patients, in order to compare this association with other reports. Fifty-one Iranian patients with psoriasis were HLA typed. The frequency of HLA antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and prov...
