Aquatic organism passage barriers have been identified as one of the key impediments to recovery of salmonids and other migratory aquatic organisms in the Pacific Northwest of the United States. As such, state and federal agencies invest millions of dollars annually to address passage barriers. Because many barriers function as ad hoc grade control structures, their removal and/or replacement c...

First, second, and third grade readers were asked to pick the item that “looked more like a word” from a pair of letter strings. The items to be discriminated differed in terms of a rule-governed description of orthographic structure. Task performance improved with school experience, averaging 58, 69, and 79% correct for first, second, and third grade readers, respectively. More importantly, re...

background: screening of students ´ health problems could lead to timely prevention and control of many health disorders. this study aimed to determine the nationwide prevalence of common disorders through school health screening program in iran methods: this cross-sectional national screening program was conducted in 2007-2008 among first- and third-grade- stu­dents in primary schools, first- ...

introduction: side weir structures are extensively used in hydraulic engineering, irrigation and environmental engineering, and it usually consists of a main weir and a lateral channel. side weirs are also used as an emergency structure. this structure is installed on one side or both sides of the main channel to divert the flow from the main channel to the side channel. lateral outflow takes p...

Objective- Bone regeneration is a multifactorial phenomenon which contributed to several factors. It is reported that risedronate is effective for musculoskeletal diseases. The current study was to determine effectiveness of the risedronate-loaded nano capsules for calvaria healing in rabbit.Design- Experimental study.Procedures- 15 white adult male New Zealand rabbits were used. Fo...

The bond strength by three point bending strength of two metal substrates (commercially pure titanium or grade II, and Ti-6Al-4V alloy or grade V) combined to three distinct low-fusing ceramic systems (LFC) and the nature of porcelain-metal fracture by scanning electron microscopy (SEM) were evaluated. The results were compared to a combination of palladium-silver (Pd-Ag) alloy and conventional...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...
