THE JOURNAL OF PROSTHETIC DENTISTRY 113 The most commonly used molds in the subspecialty of facial prosthetics are made of dental plaster and stone. The molds’ material advantages are that they are economical, time efficient, and easy to fabricate. The disadvantages are wear with repeated use for prosthesis fabrication, they must be thoroughly dry before processing with moisture sensitive facia...
As a candidate for the next generation lithography technology, nanoimprint lithography (NIL) has demonstrated its strong potential to fabricate high resolution (sub-10 nm) patterns with high throughput and low cost. One of its challenges for the acceptance of the industry is related to the mold life time that significantly affects cost of ownership and manufacturing reproducibility. Nowadays, m...
BACKGROUND Computed tomography pulmonary angiography (CTPA) may improve the diagnostic capabilities of CT imaging for invasive mold disease, but its performance relative to other signs (ie, halo sign, hypodense sign, pleural effusion, reversed halo sign) is unknown. METHODS We prospectively compared the diagnostic performance of CTPA vs other CT imaging findings in 100 patients with hematolog...
A linear perturbation method is used to solve two-dimensional heat conduction problem in which a liquid becomes solidified by heat transfer to a plane mold of finite thickness. Heat flux drawn from the lower surface of the mold is approximately uniform, but contains a small sinusoidal perturbation in one space dimension. Numerical results are obtained for the consequent sinusoidal perturbation ...
BACKGROUND Multiple studies have linked fungal exposure to asthma, but the link to severe asthma is controversial. We studied the relationship between asthma severity and immediate type hypersensitivity to mold (fungal) and non-mold allergens in 181 asthmatic subjects. METHODS We recruited asthma patients aged 16 to 60 years at a University hospital and a nearby General Practice. Patients wer...
Objectives. The study's objective was to examine the relation between mold/dampness exposure and mold sensitization among residents of Greater New Orleans following Hurricane Katrina. Methods. Patients were recruited from the Allergy Clinic of a major medical facility. Any patient receiving a skin prick test for one of 24 molds between December 1, 2005 and December 31, 2008 was eligible for the...
Simulation and modeling of macro and micro components produced by powder injection molding: A review
During the recent years powder processing technologies have gained much attention due to the less energy consumption and recyclable powders. Manufacturing of complicated parts by the conventional powder metallurgy (PM) method is hard due to the uniaxial pressure, which leads to the low design flexibility. In order to prevail these constraints, powder injection molding (PIM) process, which inclu...
