Because of the complex nature of structural characteristics, damage detection in honeycomb sandwich structures inherently carries many challenges. In the study, effects of debonding on leaky guided wave propagation in honeycomb sandwich structures are first studied by using the finite element method. A surface-bonded piezoelectric wafer actuator/sensor network is used for elastic-guided wave pr...

Abstract Aim Parastomal hernias are frequent and highly recurrent. The sandwich technique (ST) (Berger et al. [2007]) uses a double intraperitoneal mesh, whereas the retromuscular (RMT) (Pauli [2016]) dissects space, releases transversus muscle, lateralizes stoma to place mesh. aim was evaluate results of these interventions. Matherial & Methods Observational retrospective study patients wi...

The three-dimensional structure of TNF has been determined at 0.29 nm using the technique of X-ray crystallography. Published data on site-directed mutagenesis and antibody binding may now be assessed in the light of the structure, thus the links between structure and function for TNF may be addressed. TNF is a compact trimer composed of three identical subunits of 157 amino acids. The main-cha...

Diagnosis of larval migrans (LM) is usually done by immunodiagnostic methods. These methods, however, simply show the presence or absence of antibody but not the active infection of the patients. Therefore, we aimed to establish a diagnostic method for detecting circulating Toxocara canis antigen using a sandwich, ELISA. Monoclonal antibodies (MAb) were produced against the excretory-secretory ...

Despite many attractive hypotheses, neonatal necrotising enterocolitis (NNEC) remains a disease of unknown aetiology. By means of the immunofluorescent direct sandwich technique we have demonstrated immune complex deposition in the small vessels of the diseased bowel wall. We believe this is the first report of evidence of an immunological reaction occurring in this disease.

The applicability of a hapten-antihapten sandwich technique incorporating a monoclonal antihapten bridge antibody to localisation of tissue antigen is described. The results show that the method is both versatile and selective and has the potential of being even more sensitive than currently used immunoperoxidase methods.

The chain graph sandwich problem asks: Given a vertex set V , a mandatory edge set E1, and a larger edge set E2, is there a graph G= (V ,E) such that E1 ⊆ E ⊆ E2 with G being a chain graph (i.e., a 2K2-free bipartite graph)? We prove that the chain graph sandwich problem is NP-complete. This result stands in contrast to (1) the case where E1 is a connected graph, which has a linear-time solutio...

This study deals with the applications of a trigonometric shear deformation theory considering the effect of the transverse shear deformation on the static flexural analysis of the soft core sandwich beams. The theory gives realistic variation of the transverse shear stress through the thickness, and satisfies the transverse shear stress free conditions at the top and bottom surfaces of the bea...

PURPOSE Composite restorations are more frequently being placed with margins apical to the cementoenamel junction. However, margins within dentin are prone to microleakage. The purpose of this in vitro study was to evaluate various restorative procedures in terms of their ability to reduce microleakage in posterior composite restorations with gingival margins within dentin. We also examined the...
