The accurate production of a rainfall environment similar to natural rainfall by a rainfall simulator (RS) is a crucial and challenging task in rainfall instrument testing or calibration. Although the spatial uniformity of rainfall accumulation is a key parameter of an RS, the spatial uniformity comparison between simulated rainfall and natural rainfall, and the spatial uniformity improvements ...

system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...

PURPOSE Image non-uniformity may cause substantial problems in magnetic resonance (MR) imaging especially when a 3-T scanner is used. We evaluated the effect of image non-uniformity correction in gadolinium ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MR imaging using a 3-T scanner. METHODS Two commercially available methods for image non-uniformity correction, surf...

BACKGROUND Spiromax(®) is a novel dry powder inhaler for patients with asthma or chronic obstructive pulmonary disease (COPD). The studies presented here provide further data on attributes (in vitro dosing consistency with budesonide-formoterol (DuoResp) Spiromax; flow rates through empty versions of the Spiromax and Turbuhaler inhaler) of importance to patients with asthma or COPD. METHODS D...

CD-PEB temperature experiments show that post-exposure bake (PEB) temperature non-uniformity (both in steady-state and transient phases) impacts across-wafer CD uniformity [1]. Continued improvement in CD uniformity requires across-wafer temperature uniformity for the entire PEB cycle. This poses new challenges for the design of PEB thermal modules. This paper proposes a novel PEB thermal modul...

BACKGROUND Atropine sulfate is an anticholinergic agent for treatment of hypertrophic pyloric stenosis and is orally administrated as a triturate with lactose hydrate. Because of the low safety margin of atropine sulfate, triturate uniformity is a key safety factor. In this study, we assessed the uniformity of atropine sulfate in 1000-fold triturates prepared by wet mixing and dry mixing method...

The uniformity requirements of direct-drive targets are <tringent. The requirements on both sphericity and wall thickness uniformity are of the order of less than 1%. In the past, dualbeam interference microscopy has been used at LLE to characterize the wall thickness and uniformity of transparent targets.' With this technique, an interference pattern is formed between one beam that passes thro...

Imposing an extensional uniformity condition on a non-uniform circuit complexity class C means simply intersecting C with a uniform class L. By contrast, the usual intensional uniformity conditions require that a resource-bounded machine be able to exhibit the circuits in the circuit family defining C. We say that (C,L) has the Uniformity Duality Property if the extensionally uniform class C∩L ...
