Three cases of cables fire experiments with different ventilation rate in real scale electronic cabinet have been carried out. In each experiment, five cables with 14mm in out diameter and four copper conductors with 1650mm in length were used. the insulation and cover of the cables was combustible .Temperature of the fire cables, CO ,O2as well as temperature in different location in the center of the cabinet in the fire cabinet were measured as a function of time. The key role of the ventilation rate on the temperature in the center of the cabinet and the concentration of CO and O2were clearly shown, but the influence on fire spread of cable fire was not so much significantly.

Aiming at the problem of fire risk of the traditional scaffold construction scheme, a new type of scaffold construction scheme was proposed. In the vertical layout of scaffold board, this scheme alternately arranged to take the "two layers of bamboo fence one layer steel fence". In order to verify the feasibility of the prevention of the spread of fire about the new scaffold construction scheme, three groups of fire experiments were designed. By the analysis of experimental phenomena and data results, it is concluded that the steel fence boards used as isolation layers in the new scaffold construction scheme can effectively mitigate the risk of fire spreading upward or downward along the burning scaffold.

In this study, a real scale fire experiment was conducted to analyze the characteristics of the flame that is ejected from an opening. The experiment was conducted by setting mattresses and wood cribs in compartments sized 2.4 (L) × 3.6 (W) × 2.4 (H) m and using heptane as an ignition source, and changes in external heat flux and temperature were measured during the experiment. In the experiment, openings of two sizes: small [2.2 (L) × 1.0 × 1.0 (H) m] and large [2.2 (L) × 2.0 × 2.0 (H) m], were used. The results showed that the maximum decrease of 40.7 kW/㎡ and 31.7 kW/㎡ was measured in small and large openings, respectively, at the distance of 0.5 m from the top of the opening. As a test result, securing the separation distance of the upper and lower openings can greatly affect the prevention of vertical spread of the flame, and if sufficient separation distance is not secured, it is considered that an additional fire diffusion prevention method is necessary.

<p></p><p>In the present experimental study different interaction ‘modes’ those took place between a psychologist and a child were tested for the role of these towards health recovery of the child? Following were the interaction modes, a) presenting a flower with smile plus inquiring about health, b) offering a blessing plus inquiring about health, c) making an indifferent presence plus inquiring about health with flat tone, d) inquiring about health with providing precautions about prognosis. It was assumed that all modes would differently influence health outcomes? 100 hospitalized children located in child wards of different hospitals with randomized pre-post block design interacted. One each from four interaction modes was used for a group of 25 participants each. Actual ward discharge was compared with anticipatory estimated by each ward in-charge to calculate effect of mode on outcome. Face Pain Scale, The Children Happiness Scale and a Demographic Sheet were also used. Results reflected ‘modes’ relationship with outcomes. More studies would clarify further.</p><br><p></p>

Misinformation often continues to influence people’s cognition even after corrected (the ‘continued influence effect of misinformation’, the CIEM). This study investigated the role of information relevance in the CIEM by questionnaire survey and experimental study. The results showed that information with higher relevance to the individuals had a larger CIEM, indicating a role of information relevance in the CIEM. Personal involvement might explain the effects of information relevance on the CIEM. This study provides insightful clues for reducing the CIEM in different types of misinformation and misinformation with varying relevance.

This study addresses respiratory and motor impairments in an experimental reserpine-induced model of parkinsonism in rats. The role of chronic hypoxia due to diminished ventilation in the development and course of neurodegeneration is addressed. An attempt was made to distinguish between central and peripheral dopamine pathways in the mechanisms of neurodegeneration. A dissociation of putative mechanisms of respiratory and motor impairments is tackled as well. Although this purely experimental study cannot be directly extrapolated to human pathophysiology, the corollaries have been drawn concerning the potential repercussions of the respiratory and motor impairments for the physiotherapeutic procedures in the management of chronic neurodegeneration.

ABSTRACT Whistleblowing reports, if properly investigated, facilitate the early detection of fraud. Although critical, investigation-related decisions represent a relatively underexplored component of the whistleblowing process. Investigators are responsible for initially deciding whether to follow-up on reports alleging fraud. We report the results of an experimental study examining the follow-up intentions of highly experienced healthcare investigators. Participants, in the role of an insurance investigator, are asked to review a whistleblowing report alleging billing fraud occurring at a medical provider. Thus, participants are serving as external investigators. In a between-participant design, we manipulate the report type and whether the caller previously confronted the wrongdoer. We find that compared to an anonymous report, a non-anonymous report is perceived as more credible and follow-up intentions stronger. We also find that perceived credibility fully mediates the relationship between report type and follow-up intentions. Previous confrontation is not significantly associated with either perceived credibility or follow-up intentions. Data Availability: Data are available upon request.
