The optimal planning of condition-based maintenance strategy based on the degradation process is of great concerned in the past few years. A lifetime delayed degradation process with heterogenous degr...
Background: A formula low-energy diet (LED) reduces weight effectively in obese patients with knee osteoarthritis, but the role of LED in long-term weight-loss maintenance is unclear.

Background: Studies that examined dietary energy requirements (DERs) of patients undergoing maintenance hemodialysis (MHD) have shown mixed results. Many studies reported normal DERs, but some describ...
At the adult frog neuromuscular junctions (Rana pipien and Rana catesbiana), F-actin microfilaments are enriched in the nonrelease domains of nerve terminals, outside the vesicle-rich release sites. T...
The way in which the sex of an organism is determined may require lifelong maintenance, finds new research from the University of Minnesota. According to the study published today in the journal Devel...
The diapycnal flux of nitrate from the deep water provides a limit on new production in the subsurface chlorophyll maximum (SCM) during summer in stratified shelf seas. Here we estimate t...
This study was conducted to evaluate the protein requirement for maintenance of 2-year-old female Korean spotted deer. In the course of the experiment, each of three hand-reared female spotted deer wa...
Hydraulic stopple plugging machine is composed of plugging head, connecting box and hydraulic cylinder etc, which is an important equipment for oil and gas pipeline maintenance under pressure. The plu...
Connecting backtracking search with arc consistency is one of the most powerful techniques for solving distributed constraint satisfaction problems (DisCSPs) [11]. Recently, it has been considered tha...
The authors developed a prototype of a warship maintenance system. The process started by defining the maintenance requirements of warship equipment. Next, a planning scheme was development for a main...
In the process of high expansion of drainage systems and land cultivation, most natural watercourses in Lithuania were converted into drainage channels. They were deprived of all natural riparian ve...
Water quality data for the Nant Tanilwyth stream, Plynlimon (an acidic upland stream, the waters of which are of such low ionic strength that measurement is difficult), has been recorded using a new i...
Coincident measurements of chlorophyll a (Chl a) and temperature microstructure from Monterey Bay, California, U.S.A., are used to investigate the dynamics of a phytoplankton thin layer in the contex...
Two conceptual models of a two-layered frontal system are presented to study the wintertime shelf-slope front. The first model examines the geostrophic adjustment over a step topography after the fall...
