A parallel reactor setup in combination with a spatially resolving Fourier transform infrared focal plane array detector (FTIR-FPA) system in rapid scan mode has been developed which is capable of analyzing simultaneously the specific surface area of 15 copper catalysts. The system allows the reliable determination of copper surface areas with an error of about +/-1 m(2)/g. Problems are encount...

We present an experimental realization of an autonomous Maxwell's demon, which extracts microscopic information from a system and reduces its entropy by applying feedback. It is based on two capacitively coupled single-electron devices, both integrated on the same electronic circuit. This setup allows a detailed analysis of the thermodynamics of both the demon and the system as well as their mu...

Groups of six to nine Merino Summary lambs were weaned in September (May drop) and December (September drop) on to three types of irrigated perennial pastureperennial ryegrass (Lolium perenne), Ladino white clover (Trifolium repens) and lucerne (Medicago sativa), and one irrigated annual pasture-subterranean clover ( Trifolium subterraneum) . The weight gain of the weaners on white clover was s...

the effect of ca, zn and b spray application on preharvest fruit drop, sugars, calcium, zinc, and boron concentrations and as well on some physicochemical fruit properties of five commercial asian pear cultivars (‘ks’7, ‘ks’8, ‘ks’11, ‘ks’12 and ‘ks’14) was investigated under tehran province,s environmental conditions. trees were sprayed one month past fruit set until harvest within two week in...

BACKGROUND To determine the impact of body-mass factors (BMF) before radiotherapy and changes during radiotherapy on the magnitude of setup displacement in patients with head and neck cancer (HNC). METHODS The clinical data of 30 patients with HNC was analyzed using the alignment data from daily on-line on-board imaging from image-guided radiotherapy. BMFs included body weight, body height, a...

in this paper, the study deals with the lead time and setup reduction problem in the vendor-purchaser integrated inventory model. the cost of capital (i.e., opportunity cost) is one of the key factors in making the inventory and investment decisions. lead time is an important element in any inventory system. the proposed model is presents an integrated inventory model with controllable lead tim...

• High-speed imaging and DIC are used to track damage progression during impact test A proposed 3D FE model allows predicting the behavior of laminate composites [0/90] 3s laminates failed due fiber breakage at high compression impacted region [±45] exhibited matrix cracking delamination caused by tension The aim this paper is describe dynamic biaxial glass reinforced under low velocity through...

We deal with a solid manifold block and a laminated manifold block that are used for connecting hydraulic components. They are useful for reducing the space and weight of hydraulic systems. We investigate pressure drops of their pipe flow with computational fluid dynamics (CFD) and compare those of two types. The majority of all pressure drops in both types is pressure drop at corners. In solid...
