Assessing photosynthesis rates with remote sensing is important for tracking the physiological state of plants. The photochemical reflectance index (PRI) is a good estimator of short-term light-use efficiency (LUE) at the leaf scale but its responses to environmental factors are poorly understood. In this study, we assessed changes in the responses of the PRI to ozone exposure and to an increas...

The active form of vitamin D3 and some of its related compounds show neuroprotective effects in various models of neuronal damage, however, mechanism of their anti-apoptotic action has not been elucidated. Therefore, the present study was designed to investigate the effects of 1,25-dihydroxyvitamin D3 and its low-calcemic analogues, PRI-2191, PRI-1890 and PRI-1901 on staurosporine-induced apopt...

Modern pedestrian bridges tend to be long and slender in form, usually leading to a structural design with relatively low frequency primary modes of vibration. This type of structure can be excited to a nearly resonant response by various types of synchronized crowd activities and added damping is often required to prevent excessive structural motions and loadings. The three Spring Mountain Roa...

Pedestrians are the most vulnerable road users. For evaluating and modifying pedestrian safety in unsignalized crosswalks,the first important issue is to identify and explore factors affecting the interaction behavior of pedestrians andvehicles in conflict areas. By analyzing those factors and determining how they affect road user's behavior, we canrepresent the plans and proc...

Far from the world, island is world: The ecotones of Indian Ocean between creolisation and liquid borders. Due to their specific geography plural histories, societies south-western are characterised by a considerable anthropological cultural complexity. Colonial regimes migratory diasporic phenomena have strongly marked these territories on oceanic borders as well social construction particular...

Sky island scorpions shelter under rocks and other surface debris, but, as with other scorpions, it is unclear whether these species select retreat sites randomly. Furthermore, little is known about the thermal preferences of scorpions, and no research has been done to identify whether reproductive condition might influence retreat site selection. The objectives were to (1) identify physical or...

Sashka’s Technique applied to pFBP The key step in Sashka and Russel’s technique to prove lower bounds for pFBT was to prove that for each path p of length l, PrI [S(I) ⊢ PSp | I ⊢ PIp] ≤ 1 f . We extend this to a technique for pFBP. The key step is to prove that for each node v at depth l, PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ 1 f . My intuition was that PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ maxp∈v PrI [S(I) ⊢ ...

To counter the threat of insect resistance, Bacillus thuringiensis (Bt) maize growers in the U.S. are required to plant structured non-Bt maize refuges. Concerns with refuge compliance led to the introduction of seed mixtures, also called RIB (refuge-in-the-bag), as an alternative approach for implementing refuge for Bt maize products in the U.S. Maize Belt. A major concern in RIB is cross-poll...

Movable refuge chambers are a new kind of rescue device for underground mining, which is believed to have a potential positive impact on reducing the rate of fatalities. It is likely to be hot and humid inside a movable refuge chamber due to the metabolism of trapped miners, heat generated by equipment and heat transferred from outside. To investigate the heat stress experienced by miners trapp...

Introduction. Few studies have examined the association between the PR interval (PRi) and subclinical cardiovascular disease measures. Methods and Results. The Multiethnic Study of Atherosclerosis (MESA) is a population-based study of 6814 men and women aged 45-84 years without clinical cardiovascular disease and 4962 had complete baseline data on cardiac magnetic resonance imaging measures of ...
