objective about 1 % of infants are of very low birth weight. however, they comprise about 50% of infant mortality. we compare the effects of continuous versus intermittent feeding on physical growth, gastrointestinal tolerance and macronutrient retention in low birth weight infants (methods a prospective randomized trial clinical trial was performed from 2004-2005. very low birth weight neonate...

The strongly spin-dependent absorption of neutrons in nuclear spin-polarized (3)He opens up the possibility of polarizing neutrons from reactors and spallation sources over the full kinematical range of cold, thermal and hot neutrons. This paper gives a report on the neutron spin filter (NSF) development program at Mainz. The polarization technique is based on direct optical pumping of metastab...

In view of the working principle a swashplate axial piston pump, simulation model pump was built in AMESim and its output flow pulsation characteristics were simulated analyzed. We mainly analyzed influence speed prime mover, angle, diameter piston, port plate structure on pump. The result this research shows that structure, mover have an important order to effectively reduce generated by noise...

The first roller pump was patented in 1855 by Porter and Bradley and was hand operated. A modification first named "surgical pump", designed and manufactured by E. E. Allen in 1887, was intended for direct blood transfusion. Truax, who also distributed and promoted the Allen pump with one roller, developed the first double roller pump in 1899. In the following decades, several researchers, incl...

INTRODUCTION As part of a reconsideration of coverage policy, the Centers for Medicare and Medicaid Services requested a systematic review of the evidence on the use of pneumatic compression devices in the home environment for treatment of chronic venous insufficiency (CVI) and venous ulcers. METHODS Articles were found with a systematic literature search of MEDLINE, EMBASE, and AMED (Allied ...

An 81-year-old male with an implanted DDD pacemaker reported fluctuating edema accompanied by pain and paresthesia affecting the hand arm on side had been implanted. These symptoms, which developed several weeks after procedure, were more pronounced in morning resolved during day. Venography showed axillary vein compression, whose severity varied different positions. Changing location of pocket...
