In the ancient American Southwest, use of the bow developed relatively rapidly among Pueblo people by the fifth century AD. This new technology replaced the millennia-old atlatl and dart weaponry system. Roughly 150 years later in the AD 600s, Pueblo socioeconomic organization began to evolve rapidly, as many groups adopted a much more sedentary life. Multiple factors converged to allow this se...

This paper presents a broadband and compact planar quasi-Yagi antenna for multi-band 3G/4G applications. The proposed quasi-Yagi antenna consists of a modified bow-tie driver to increase the bandwidth, a passive reflector and two passive directors to enhance the directivity at the lower and higher ends of the operating band, respectively. A microstrip-to-slotline transition feed is used to achi...

Objective To reduce unnecessary orthopedic referrals by developing a protocol for managing physiologic bow legs in the primary care environment through the use of a noninvasive technique that simultaneously tracks normal varus progression and screens for potential pathologic bowing requiring an orthopedic referral. Methods Retrospective study of 155 patients with physiologic genu varum and 10...

Bingham and Souza have presented an evolutionary theory that specifies a causal relationship between the advent of powerful projectile weapons such as the bow and radical rearrangements in social relations and histories. They propose that the acquisition of weapons that permitted humans to kill at ever-increasing distances provided the coercive means to suppress conflicts of interest among nonk...

conclusions the frequency of rls among our patients was remarkable and we conclude that all patients who are undergoing hemodialysis should be screened for rls, which can assist in providing proper attention and treatment. results according to our results, 54.5% of patients were diagnosed with rls, and of those 65.2% and 42.9% were women and men, respectively. rls is seen more often among patie...

a total of 150 day old female chickens (ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. the two experimental treatments were: 1) chicks that reared under normal temperature (nt) and 2) chicks that reared under cold tempe...
