صخلملا A total of 48 fresh water fishes, belonging to four species of the family Cyprinidae (Capoeta trutta, Chalcalburnus mossulensis, Cyprinion macrostomum and Leuciscus lepidus) were collected from Darbandikhan lake, southwest Sulaimaniya city, Kurdistan region, in the north of Iraq, from March to the end of July 2008. The inspection of gills revealed the infection of these fishes with four ...

It is an effective way to improve the flexural behavior of reinforced concrete (RC) members by externally bonded carbon fiber reinforcement polymer (CFRP) laminates on the soffit of the members. However, there is little investigation on flexural performance of RC beam flexurally strengthened by side-bonded FRP laminates. To investigate the flexural behavior of RC beams side-bonded CFRP laminate...

Overproduction of nitric oxide (NO) by inducible NO synthase contributes toward refractory hypotension, impaired microvascular perfusion, and end-organ damage in septic shock patients. Tetrahydrobiopterin (BH4) is an essential NOS cofactor. GTP cyclohydrolase 1 (GCH1) is the rate-limiting enzyme for BH4 biosynthesis. Under inflammatory conditions, GCH1 activity and hence BH4 levels are increase...

This paper reports the effects of carbon fiber-reinforced polymer (CFRP) length on the failure process, pattern and crack propagation for a strengthened concrete beam with an initial notch. The experiments measuring load-bearing capacity for concrete beams with various CFRP lengths have been performed, wherein the crack opening displacements (COD) at the initial notch are also measured. The app...

Basalt fiber is a low cost materiel obtained from the rock earth, and it can be divided into small pieces to form fiber. In this paper dealing with manufacturing, property of composites application are reviewed. The results indicate that as compared glass fibers, carbon fibers armide fiber, basalt possesses excellent machine driven properties such wave permeability, electrical properties, non-c...
