BACKGROUND Up to 70% of hospitalized older people experience a deterioration of their functional capacity during the course of hospital stay. This change has a dismal effect of quality of life and prognosis. AIM To assess the change in functional status of older people during the course of hospitalization in a geriatric unit. MATERIAL AND METHODS Review of medical records of 83 patients wit...

It is generally accepted that the electrochemical discharge capacity of a hydrogen storage alloy is closely related to its crystal characteristics. From our experiment, the discharge capacity of AB type Laves phase hydrogen storage alloy ZrCr Mn V Ni 2 0.4 0.2 0.1 1.3 21 21 decreased sharply from 324 mAh g to 25 mAh g after amorphization by mechanically milling the crystalline (as-cast) alloy w...

OBJECTIVE To investigate the time-courses of lung function and respiratory muscle pressure generating capacity after spinal cord injury. DESIGN Multi-centre, prospective cohort study. SUBJECTS One hundred and nine subjects with recent, motor complete spinal cord injury. METHODS Lung function and respiratory muscle pressure generating capacity were measured at first mobilization, at discha...

Here, we report a facile hydrothermal approach for synthesizing anatase TiO2 hierarchical mesoporous submicrotubes (ATHMSs) with the aid of long-chain polymer as soft template. The TiO2 nanocrystals, with sizes of 6-8 nm, are well interconnected with each other to build tubular architectures with diameters of 0.3-1.5 μm and lengths of 10-25 μm. Such highly porous structures give rise to very la...

A SnO/SnO2/GNS composite with controlled oxidation states and composition has been prepared through simple one-pot reduction of an EG suspension of SnCl2 and graphene oxide. The as-prepared composite was characterized by XRD, FT-IR, XPS, SEM, TEM and BET. SnO and SnO2 nanoparticles are uniformly distributed on the surface of the graphene. Taking advantage of the high electron conductivity of gr...

In spite of recent progress, there is still a lack of reliable organic electrodes for Li storage with high comprehensive performance, especially in terms of long-term cycling stability. Herein, we report an ideal polymer electrode based on anthraquinone, namely, polyanthraquinone (PAQ), or specifically, poly(1,4-anthraquinone) (P14AQ) and poly(1,5-anthraquinone) (P15AQ). As a lithium-storage ca...

Abstract Climate change has caused the inefficient operation of a significant number old weirs to pass large discharges. Therefore, this study aims increase discharge capacity labyrinth weir. A new approach was proposed by modifying weir structure. The data obtained from quarter-round crest and different sidewall angles ranging 8 35°. conventional used for comparison. results showed that percen...
