One of the primary flaws with current digital signature technology is that a digital signature does not “feel” or resemble a traditional seal or personal signature to the human observer; lacking a sense of visualisation and changing each time it is applied. This paper reviews the historical value of seals in Eastern and Western cultures to provide a basis to enhance global acceptability of exis...

OBJECTIVE The aim of this study was to the determine impact of severe esophageal anastomotic leak (SEAL) upon long-term survival and locoregional cancer recurrence. BACKGROUND The impact of SEAL upon long-term survival after esophageal resection remains inconclusive with a number of studies demonstrating conflicting results. METHODS A multicenter database for the surgical treatment of esoph...

OBJECTIVES To evaluate in vitro the effect of cavity preparation with microburs and diamond-coated ultrasonic tips on the microleakage and marginal fit of six end-root filling materials. STUDY DESIGN. The following materials were assessed: amalgam (Amalcap), zinc oxide eugenol (IRM), glass ionomer (Vitrebond), compomer (Cavalite), mineral particle aggregate (MTA) and composite (Clearfil). Cavit...

An ultrasonic testing method employing the pulse-echo inspection technique was developed to assess the integrity of annular seals surrounding casings (i.e.. instrument tubes or well casings). This nondestructive testing method permits testing aseal from inside acasing without disturbing the casing, seal. or formation. Seals constructed with cement-based and bentonite-based sealants surrounding ...

Recently, there has been increasing concerns over bifacial PV (BPV) modules the conventional monofacial (MPV) owing to their potential add extra electrical energy from rear-side irradiance. However, adding irradiance front-side results in increased nonlinearity of BPV compared MPV modules. Such makes methods unable accurately extract module parameters. In this context, precise determination par...

The carrying capacity of the French Frigate Shoals (FFS) region for the endangered Hawaiian monk seal was appraised using an updated version of the original FFS Ecopath model (Polovina 1984). Model parameters were updated using recent literature, and data from surveys of the seal population and its bottom-associated prey. Together they produced a static mass balance model for 1998 when the prey...

Security and reliability are the main focus of annular metal seal assembly. It is concluded that the factors influence sealing performance of annular metal seal assembly most in view of working conditions of annular metal seal assembly. Taking major influencing factors with response surface method (RSM) analysis, and determining coefficient of regression analysis with finite element method (ANS...

In this paper we summarize the status of bifacial photovoltaics (PV) and explain why move to bifaciality is unavoidable when it comes e.g., lowest electricity generation costs or agricultural PV (AgriPV). Bifacial modules—those that are sensitive light incident from both sides—are finally available at same price per watt peak as their standard monofacial equivalents. The reason for solar cells ...
