This paper describes an experimental investigation into the seismic behavior and efficiency of steel frames with special bracing infills. Cold formed steel studs (CFSS), typically used in nonstructural partition walls, were studied to determine if they could be used to laterally restrain braces against buckling and thus enhance their seismic performance. Four specimens were ductile designed and...

The steel frame-reinforced concrete core tube structural system is widely used in mid-rise and high-rise buildings due to its good seismic behaviour high construction efficiency. Since the frame reinforced are supposed deform synergistically under earthquake action, beam-concrete wall joint (SBCW for short) will be subjected a significant pull-out force. Therefore, pulling resistant capacity of...

Steel–ultra-high-performance concrete (UHPC) composite beams offer numerous advantages, such as structural self-weight reduction, bending stiffness improvement, and tensile cracking limitation in slabs. However, few studies have focused on the shear performance of short stud connectors steel–UHPC structures. To this end, push-out tests were carried out to evaluate effect slab thickness, diamete...

BACKGROUND In the last few years stud farms have experienced increasing problems with Parascaris equorum infections in foals despite intensive deworming programs. This has led to the question as to whether the anthelmintic drugs used against this parasite are failing. This study aimed to investigate the efficacy of ivermectin, fenbendazole and pyrantel on the faecal output of ascarid eggs of fo...

of pulmonary histoplasmosis as well as blastomvcosis, aspergillosis and other fungus diseases. The characteristics of cavities in pulmonary tuberculosis have long been studied by various methods including the transthoracic introduction of a contrast medium. This is a studs’ of cavities and bronchi in pulmonary fungus diseases. The findings are compared with those in previous studies” of tubercu...

A nail gun is a powder-actuated tool used widely in the construction industry. It uses powder charges to fire a variety of nails and studs into steel , wood, or concrete. Numerous injuries to the body with several deaths from the use of this tool have been reported. Twenty craniocerebral injuries have been reported in the world literature [1-13]; however, cerebral angiography has not been descr...

Abstract Reinforced concrete as the most important construction material suffers from long-term deterioration due to different exposure conditions. Fire attack is a critical condition it can lead complete collapse of structure. On other hand, repair and strengthening existing structures have become necessary both technically financially. Moreover, since high-performance concretes (HPCs) are ext...

Ovaries of 17 adult, pleuriparous, and lactating one-humped she-camels (Camelus dromedarius) were examined per rectum for uterine involution and for presence of follicles (>/=1.0 cm diameter) by real-time ultrasonography at the National Research Centre on Camel at Bikaner, India at 30, 45, 60, 75, and 90 days postpartum. Involution was completed from 25 to 30 days postpartum and follicles (>/=1...
