The objective of this study was to compare single-needle arthrocentesis with distension of the upper compartment of the temporomandibular joint (TMJ) with the conventional two-needle arthrocentesis. Twenty-six patients with articular disc displacement without reduction (DDWOR) were included in the study and assigned to two groups (n = 13): single-needle arthrocentesis with distension of the upp...

BACKGROUND This study evaluated dynamic changes in eyebrow position related to aging. METHODS Female participants were recruited and separated into two groups aged 20-30 years (the younger group, n=20; mean age, 24.8 years) and 50-70 years (the older group, n=20; mean age, 55.8 years). Photogrammetry was used to determine the eyebrow position at the medial canthus (MC), lateral limbus, latera...

In this paper a method for detection of microcalcifications (MCCs), which appear at the beginning stages of breast cancer, is presented by using mathematical morphology. This method consists of four steps. At the first step the contrast of suspicious regions on the image is enhanced by contrast stretching. In the next step a morphological filtering process is applied by using six different stru...

A 2-dimensional, elastic-plastic finite element model has been developed to simulate plasticity induced crack closure in slanted and deflected cracks growing outside the small scale yielding (SSY) regime. The finite element model allows for contact between deformable surfaces to capture the complex contact interaction between the crack faces. Coulomb’s friction law has been used to model fricti...

Third-party reviews play an important role in many contexts in which tangible attributes are insufficient to enable consumers to evaluate products or services. In this paper, we examine the impact of professional and amateur reviews on the box office performance of movies. Using a simple diffusion model, we establish an econometrics framework to control for the interaction between the unobserva...

Morphological openings and closings form the cornerstones of a rich set of nonlinear operators in signal processing. In this paper, we show how a new morphological operator can be constructed that serves as an approximation to openings and closings for images corrupted by low levels of noise. 2001 Elsevier Science B.V.

The discovery and subsequent study of microquasars lead to major progress in our understanding of: 1) the nature of relativistic jets seen elsewhere in the universe, and 2) the connection between the accretion onto compact objects and the formation of collimated jets. A detailed account of the major progress accomplished until present was published in Annual Review of Astronomy & Astrophysics (...

Determination of stomatal densities of the banana peel (Musa acuminata L. var Hort. Valery) by microscopic observations showed 30 times fewer stomates on fruit epidermis than found on the banana leaf. Observations also showed that peel stomates were not laid down in a linear pattern as on the leaf.It was demonstrated that stomatal responses occurred in banana fruit. Specific conditions of high ...

UNLABELLED The aim of the study was to estimate the effect of arthrocentesis in the treatment of osteoarthritis of the temporomandibular joint (TMJ), evaluate and compare cytological and biochemical findings in the synovial fluid (SF) as well in venous blood samples and to determine the effectiveness of arthrocentesis with regard to TMJ pain intensity and mandibular movement.
