Abstract: nanocrystalline nickel samples with the grain size of ~25 nm were prepared via direct current electrodeposition andaluminized for different durations by pack cementation method at 500 means of SEM, EDS and XRD techniques. According to results, short time aluminizing resulted in the formation of asingle aluminide layer whereas at long duration two distinct aluminide layers were formed....

A Simple Approach to Treatment Effects on Durations When the Treatment Timing is Chosen When a treatment unambiguously defines the treatment and control groups at a given time point, its effects are usually found by comparing the two groups’ mean responses. But there are many cases where the treatment timing is chosen, for which the conventional approach fails. This paper sets up an ideal causa...

Abstract This study aimed to examine intra-individual differences in both duration and passage of time (PoT) judgments, the relationships between them, for a wide range durations going from few hundred milliseconds several minutes. Participants performed with within-subjects design (200–400 ms), seconds (2–4 s), tens (20–40 s) minutes min) ranges. For results revealed individual temporal accura...

Neural tuning to different sound durations may be a useful filter for identification of certain sounds, especially those that are biologically important. The auditory midbrains of mammals and amphibians contain neurons that appear to be tuned to sound duration. In amphibians, neurons are tuned to durations of sound that are biologically important. The purpose of this study was to characterize r...

OBJECTIVES Clinical-diffusion magnetic resonance imaging (MRI) mismatch (CDM) in patients with anterior circulation occlusions is an optional method used to select patients for recanalisation outside the 3-h time window. A similar concept has not been reported with posterior circulation occlusions. METHODS CDM was defined as a Glasgow Coma Scale (GCS) score <8 with DWI lesions not located in ...

results overall, 3 (15%) subjects achieved svr, 10 cases (50%) relapsed after treatment cessation and 7 (35%) patients did not clear hdv during the treatment. conclusions hdv coinfection with hbv had very low response rate to high doses and long durations of ifn α-2b therapy. objectives we aimed to determine the efficacy of ifn α-2b therapy in patients with hbv/hdv coinfection. patients and met...

Forty-three US Geological Survey gauges with records greater than 15 yrs located in watersheds less than 250 km were used to model the effects of suburbanization on streams in semi-arid southern California. The watersheds spanned a gradient of urban development, ranging 0–23% total impervious area in 2001. With little flow control at the subdivision scale, most impervious area in the region is ...
