hearing loss can affect physical, mental and social health of deaf adults and lead cause depression, anxiety, isolation, suspicion and stress. this study was aimed to compare mental health in the hearing-impaired elderly with hearing aid and hearing-impaired elderly without hearing aids referring to ahvaz imam khomeini hospital. in this cross- sectional study, the participants included 72 heari...

conclusions the two key requirements of the first aid and transportation courses are practicality and managerial engagement. we developed and provided specific guidance of fat curriculum by using the study findings. this curriculum is recommended for educating fat staffs, paramedics, emergency technicians, and military nurses. results study participants’ experiences of wartime first aid and tra...

in the current study, the efficiency of starch and plantago ovata extract as coagulant aids is compared in water turbidity removal. the coagulant is ferric chloride and the experiments are run in two ranges of ph 7 and 8. the achieved results of turbidity removal in different turbidity levels of 100, 50 and 20 ntu caused by different concentrations of starch and p.ovata as coagulant aids besid...

a palatal defect may result from surgical resection, and its consequences could include difficulty in speech and nasal regurgitation of food and liquids. an obturator combined to speech aid prosthesis can improve nasal emission during speech,  and  assist  in  preventing  nasal  regurgitation  of  food.  this  article presents a clinical report of the reconstruction of palatopharyngeal function...

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...

Two-phase single-case designs, including baseline evaluation followed by an intervention, represent the most clinically straightforward option for combining professional practice and research. However, unless they are part of a multiple-baseline schedule, such designs do not allow demonstrating a causal relation between the intervention and the behavior. Although the statistical options reviewe...

In Sub-Saharan Africa, 40% of the burden of disease and injury can potentially be addressed by emergency care. Adequate pre-hospital care is vital, but often unavailable in Sub-Saharan Africa. Initial help and emergency transport often depends on basic first responders. The World Bank identified first aid training as cost-effective way to save lives in Sub-Saharan Africa. Although well-intentio...

The methods used at the Clinical Research Centre, Northwick Park Hospital, to treat wounds potentially infected with neurotropic viruses are outlined. Emphasis is laid on first aid and on surgical attention. Patients should remain under medical supervision for at least four weeks after the injury, the need for specific post-exposure treatment depending on the nature of the exposure.

We calculate momentum transport from tearing fluctuations in a reversed field pinch with sheared flow, considering both the effect of a single tearing mode (through quasilinear theory and MHD computation) and multiple tearing modes (through nonlinear MHD computation). A single tearing mode transports momentum, via Maxwell and Reynolds stresses, more rapidly than classical viscous forces. Moreov...

BACKGROUND Anecdotal evidence reported an outbreak of symptoms on Fraser Island during the late 1990 s similar to those expected from exposure to dermotoxins found in the cyanobacterium L. majuscula. This coincided with the presence of a bloom of L. majuscula. METHODS Records from the Fraser Island National Parks First aid station were examined. Information on cyanobacterial blooms at Fraser ...
