A small and lightweight signal conditioning unit for use with strain-gage transducers is described. The unit provides bridge-balancing, amplification, and filtering for three channels of Wheatstone bridge circuits. The electronics are housed with a 4.5 cm x 3.0 cm x 2.5 cm box that allows connection to a transducer and to a cable that extends to power supplies and a data storage facility. Evalu...

We introduce a new class of edge labelings for locally finite lattices which we call SB-labelings. We prove for finite lattices which admit an SB-labeling that each open interval has the homotopy type of a ball or of a sphere of some dimension. Natural examples include the weak order, the Tamari lattice, and the finite distributive lattices.

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...

A newborn female infant presented at birth with a congenital, 33 · 25 · 25-mm mass located on the nasal bridge and protruding along the left nasopalpebral region (Fig. 1). The lesion had never bled and there were no problems associated with feeding or breathing. Physical examination revealed a round, solid, nonpulsating, painless tumor covered by erythematous skin with superficial telangiectasi...

OBJECTIVE To analyze patterns and frequency of recurrences of squamous cell carcinoma (SCC) of the vulva after wide local excision (WLE) and superficial inguinal lymphadenectomy with separate incisions and to identify prognostic factors for the development of recurrences. METHODS Between January 1985 and December 1999, all 125 consecutive patients with primary SCC of the vulva, treated with W...

BACKGROUND Considering the common origin of skin and peripheral nervous system, a tube of dermal layer of skin hypothetically can be an ideal conduit for nerve reconstruction. An experimental study performed to evaluate the nerve regeneration of efficacy into a dermal tube. METHODS Sixty male Wistar rats were used. A 10 mm gap was produced in right sciatic nerves. In group A the autogenous ne...

BACKGROUND Psoriasis is a chronic inflammatory skin disorder involving marked immunological changes. IL-17-targeting biologics have been successful in reducing the disease burden of psoriasis patients with moderate-to-severe disease. Unfortunately, the stratum corneum prevents penetration of large molecule weight proteins, including monoclonal antibodies. Thus, for the majority of psoriasis pat...

OBJECTIVE To study the effects of an oronasal interface (OI) for noninvasive ventilation, using a three-dimensional (3D) computational model with the ability to simulate and evaluate the main pressure zones (PZs) of the OI on the human face. METHODS We used a 3D digital model of the human face, based on a pre-established geometric model. The model simulated soft tissues, skull, and nasal cart...
