Recently, ultrafast lasers exhibiting high peak powers and extremely short pulse durations have created a new paradigm in materials processing. The precision and minimal thermal damage provided by ultrafast lasers in the machining of metals and dielectrics also suggests a novel application in obtaining precise cross-sections of fragile, combustible paint layers in artwork and cultural heritage ...

A double-blind, randomized, vehicle-controlled, parallel-group trial was performed to compare the efficacy and tolerability of tazarotene 0.1% gel and vehicle gel in 31 patients with fingernail psoriasis. Patients were randomized to receive tazarotene or vehicle gel, which they applied each evening for up to 24 weeks to 2 target fingernails, one under occlusion and one unoccluded. The tazaroten...

This multiple single case study contrasted left hemisphere stroke patients (N = 6) to healthy age-matched control participants (N = 15) on their understanding of action (e.g., holding, clenching) and motion verbs (e.g., crumbling, flowing). The tasks required participants to correctly identify the matching verb or associated picture. Dissociations on action and motion verb content depending on ...

The sources and mechanisms of soluble salt uptake by porous limestone and the associated degradation patterns were investigated for the life-sized 15th century "entombment of Christ" sculpture group located in Pont-à-Mousson, France, using a multi-isotope approach on sulphates (δ(34)S and δ(18)O) and nitrates (δ(15)N and δ(18)O). The sculpture group, near the border of the Moselle River, is wit...

The images shown here 1 explore inside the 30 km exclusion zone surrounding the Chernobyl Power Plant. Evacuated with 24 hours notice after the 1986 melt down of one of its three nuclear reactors, the zone now stands as a symbol of the dangers inherent within the nuclear process. Empty villages strewn with the reminders of their former populations are scattered throughout the zone and at its ce...

AIM This paper presents a discussion of the current state of joint chair or clinical chair positions in nursing. Background.  Joint chair positions in nursing or midwifery have been popular approaches to developing clinical research and to bridging the 'theory-practice gap'. Recent personal observations and commentaries in the literature suggest that the service-academy consensus that underpinn...

HANDMADE PAPER OF THE Middle Ages and earlier, housed in the rare book rooms of libraries, is often in excellent condition. The machinemade paper of the last 150 years, in the general collection, is as often brittle and crumbling. The failure of machine-made paper to endure has been a disaster for the records of this civilization. Recently, however, methods of making long-lasting paper on the p...

Abstract Much stone sculptural and architectural heritage is crumbling, especially in intense tropical environments. This exemplified by significant losses on carvings made of tuff at the Classic Maya site Copan. Here we demonstrate that Copan primarily decays due to stress generated humidity-related clay swelling resulting spalling material loss, a damaging process appears be facilitated micro...

Purpose: This is to analyze the level of knowledge government's COVID-19 stimulus package among SMEs in Cape Coast Metropolitan area. Research methodology: Quantitative and descriptive approaches were used investigation. Purposive sampling was sample 234 SMEs; a structured questionnaire gather data; inferential statistics used; SPSS version 20 enter, transform, data. Results: The result indicat...

Studies indicate that about 23 percent to 28 percent of the physicians working and residing in the United States, Canada, Australia, the UK and New Zealand were born and trained in the low-income countries, areas suffering from critical shortages of physicians and other health workers. In the US alone, the preponderance of the foreign physicians hails from South Africa, Philippines, India, Paki...
