Abstract The mismatch between illumination and traffic safety brightness in tunnels leads to much-wasted lighting energy problems. Effective control of tunnel can be achieved by on demand reducing consumption. This paper uses the curve fitting linear interpolation methods optimize luminance reduction factor K proposed Highway Tunnel Lighting Rules. It constructs a multi-zone division speed, flo...

Numerous factors may contribute to high-severity crashes in highway work zones. Identifying these factors and then alleviating their impact is a challenging task that traffic engineers and researchers have to confront. In this study, the work zone risk factors that could increase the probability of causing fatalities when severe crashes occur were examined using a comprehensive approach. The re...

Neural stem cells in the subventricular zone (SVZ) continue to generate new neurons in the adult brain. SVZ cells exposed to EGF in culture grow to form neurospheres that are multipotent and self-renewing. We show here that the majority of these EGF-responsive cells are not derived from relatively quiescent stem cells in vivo, but from the highly mitotic, Dlx2(+), transit-amplifying C cells. Wh...

Whereas neurons of the lower layers (VI-V) of the cerebral cortex are first born from dividing precursors at the ventricular zone, upper layer neurons (II-IV) subsequently arise from divisions of intermediate neuronal precursors at the subventricular zone (SVZ). Little is known about mechanisms that control the proliferation of SVZ neuronal precursors. We herein report that the restricted expre...

and school staff. therefore, it is essential to pay continuous and specific attention to safety problems in schools. we identified 20 critical success factors (csfs) in the current study based on previous researches in order to achieve effective school safety. then these factors validated by 33 governmental high school administrators. this survey was conducted in tehran, among 96 governmental h...

Factor XIII deficiency (FXIIID) is an extremely rare hemorrhagic disorder with a prevalence of 1/3-5 million. Management of disease is performed by fresh frozen plasma (FFP), Cryoprecipitate (CP) or FXIII concentrate (Fibrogammin P®). Our objective was to assess safety and effectiveness of Fibrogammin P® in patients with FXIIID. For this purpose we designed this long-term follow up study on a l...
