Adhesively bonded joints are commonly used in airframe structures due to their superior strength to weight ratio, lower maintenance cost, and longer service life. The bonded joint reliability is affected by the environmental conditions, such as moisture, temperature, and service environment. In this study, the role of contamination during the bonding process on the joint mechanical integrity is...

A bi-stable switching energy harvester made from a buckled steel structure mounted with uniaxially poled piezoelectric polyvinylidene fluoride and 3D printed polylactic acid components is constructed and tested. A data collection system and frequency sweeping program is built to drive the device using a custom compression rig fitted with an accelerometer. The energy harvester is tested with the...

Abstract Introduction The recent BASKETSMALL2 trial demonstrated safety and efficacy of drug coated balloon (DCB) angioplasty for de novo small vessel disease. Registry data have that DCB is safe; however, the majority these studies are limited due to long recruitment time number patients with compared eluting stents (DES). Our aim was investigate if DCB-only strategy safe incorporate in routin...

Misunderstanding of driver correction behaviors (DCB) is the primary reason for false warnings of lane-departureprediction systems. We propose a learning-based approach to predicting unintended lane-departure behaviors (LDB) and the chance for drivers to bring the vehicle back to the lane. First, in this approach, a personalized driver model for lanedeparture and lane-keeping behavior is establ...

The biochemical analysis of cellulose biosynthesis by plants has been a difficult problem due to the lack of a reliable assay procedure for cellulose synthase activity. Recently, the celA1 gene was cloned from cotton fiber, and this gene was identified from the rsw1 mutant of Arabidopsis as a catalytic subunit of cellulose synthase (Arioli et al. 1998). The cloning of these genes enables us to ...

where A,B ⊂ B(H), and the distance between A⊗Mn and B ⊗Mn is measured in B(H) ⊗ Mn ∼= B(H). We also investigate the consequences of “complete closeness”, i.e. what can be said when dcb(A,B) is small? For example, if dcb(A,B) is small, then any projection p ∈ A ⊗ Mn can be suitably approximated by a projection q ∈ B ⊗ Mn, leading an isomorphism K0(A) → K0(B) which maps [p]0 to [q]0. This strateg...

Calcineurin, a Ca(2+)/calmodulin-dependent Ser/Thr phosphatase (protein phosphatase 2B), plays a critical role in IL-2 production during T cell activation. It has been previously reported that IL-2 release in activated Jurkat T requires caspase-like activity (Posmantur et al. (1998) Exp. Cell. Res. 244, 302-309). We report here that the 60-kDa catalytic subunit of calcineurin A (Cn A) was parti...

(2005) Fracture behavior of polyetherimide (PEI) and interlaminar fracture of CF/PEI laminates at elevated temperatures. Abstract To investigate effects of environmental temperature on fracture behaviour of a polyetherimide (PEI) thermoplastic polymer and its carbon fibre (CF/PEI) composite, experimental and numerical studies were performed on compact tension (CT) and double cantilever beam (DC...

The mechanical behavior of electrically conductive adhesive joints exposed to elevated temperature and relative humidity conditions has been investigated, and failure mechanisms of conductive adhesive joints have been determined. Three model, silver-filled, epoxy-based adhesive systems have been studied in conjunction with printed circuit board (PCB) substrates with metallizations of Au/Ni/Cu a...
