nowadays “design” is considered as an independent discipline which is neither a science, nor an art, but an interdiscipline with strong relations with both art and science. therefore, this new understanding demands reidentifying all design sub-disciplines. “space” as one of this sub-disciplines, has a pivotal role in shaping form in both design and architecture. while concrete understanding of ...

December 2004 • Journal of Forestry Historically, many issues in US forest policy have involved heated exchanges between timber interests and environmental groups over the future of the nation’s national forests. Debate about whether national forests should produce timber and rural economic opportunities, or pursue other objectives such as ecological restoration and recreation, generally ignore...

planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

100 patients (93 females and 7 males) in ages ranging between 23 and 65 years were subjected to laparoscopic cholecystectomy for biliary colic (92 pts), acute cholecystitis (7 pts) or asymptomatic gallstones (1 pt). none had a history of icterus and in every case choledocholithiasis was excluded by means of serum alkaline phosphatase assessment and sonography (in addition to ercp in 3 pts). 3 o...

mohammed, north, and ashton find that decentralization in fiji shifted health-sector workloads from tertiary hospitals to peripheral health centres, but with little transfer of administrative authority from the centre. decisionmaking in five functional areas analysed remains highly centralized. they surmise that the benefits of decentralization in terms of services and outcomes will be limited....

The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...

New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...
