an integrated model for magnetoencephalography (meg) and functional magnetic resonance imaging (fmri) is proposed. in the proposed model, meg and fmri outputs are related to the corresponding aspects of neural activities in a voxel. post synaptic potentials (psps) and action potentials (aps) are two main signals generated by neural activities. in the model, both of meg and fmri are related to t...

introduction: diabetes is the most common disease related to metabolism disorders with long term complications. it needs lifelong specific self-care, as it causes a promotion in quality of life and decreases disease costs. the health belief model (hbm) is a psychological model that attempts to explain and predict health behaviors. this is done by focusing on the attitudes and beliefs of individ...

background hiv/aids is one of the major public health problems and a barrier to the progress of human civilization that is considered as a big concern for people all around the world. premarital sexual abstinence is introduced as the most effective way to avoid hiv/aids. this study aimed to determine associated factors in the preventing behaviors of hiv/aids among young people using the extende...

The thin film used for the NASA Ultra Long Duration Balloons (ULDB) shows considerable time-dependent behaviour. Furthermore, experiments on scaled ULDB balloons have revealed that wrinkles are present over a wide range of pressures. A numerical model has been developed describing the nonlinear anisotropic viscoelastic material behaviour by means of a Schapery-type model and this model has been...

Mounting evidence of chemical disequilibria in the Venusian atmosphere has heightened interest search for life within planet’s cloud decks. Balloon systems are currently considered to be superior class aerial platform extended atmospheric sampling clouds, providing highest ratio science return risk. Balloon-based designs depend heavily on payload mass and target altitudes. We present options co...

It is generally recommended that an esophageal balloon-catheter possess an adequate frequency response up to 15 Hz, such that parameters of respiratory mechanics may be quantified with precision. In our experience, however, we have observed that some commercially available systems do not display an ideal frequency response (<8-10 Hz). We therefore investigated whether the poor frequency respons...

Due to significant spatial and temporal changes in the cosmic radiation field, radiation measurements with advanced dosimetric instruments on board spacecrafts, aircrafts and balloons are very important. The Hungarian CoCoRAD Team was selected to take part in the BEXUS (Balloon Experiment for University Students) 12&13 project. In the frame of the BEXUS programme Hungarian students from the Bud...
