Sand dunes are found in a wide variety of shapes in deserts and coasts, and also on the planet Mars. The basic mechanisms of dune formation could be incorporated into a continuum saltation model, which successfully reproduced the shape of the barchan dunes and has been also applied to calculate interaction of barchans in a field. We have recently extended our dune model to investigate other dun...

INTRODUCTION The interpretation of the Mantoux test, as well as knowledge of factors that affect the test's induration size, is significant for the early diagnosis of tuberculosis in children. AIMS To determine the Mantoux test induration cut-off size which distinguishes between positive and negative results in Macedonian children suffering from tuberculosis. To find whether there is any corr...

We report a new case of postvaccination morphea profunda (MP) in a child and discuss its different clinical presentations, prognosis, and therapy and its relationship with "solitary morphea profunda." A 2-year-old healthy girl presented with an induration of the anterior aspect of the left thigh of 9 months duration. The lesion had appeared 3 months after a third dose of diphtheria-tetanus-pert...

A progression of induration, erosion, and redeposition of transverse and networked transverse aeolian ridges (TARs) has been documented in the Medusae Fossae Formation (MFF), Mars. Cratered and eroded aeolian bedforms are rarely observed on Mars, indicating that those found in the MFF have been inactive for much longer than those found elsewhere. Indurated TARs are observed to grade into facete...

Induration is a characteristic feature of delayed-type hypersensitivity skin reactions and is the usual measure of their intensity. The precise basis of induration has not been established, although activation of the clotting system with consequent fibrin deposition has been clearly implicated. In this study, two subjects with congenital afibrinogenemia, a genetic defect in fibrinogen synthesis...

OBJECTIVE To determine the response of stubborn psoriatic plaques to the 308-nm excimer laser. DESIGN Controlled study with a before-after design. SETTING A university-based clinical research center. PATIENTS Adult subjects with recalcitrant plaque psoriasis that have not responded to other therapies for at least 2 months. INTERVENTIONS Selected psoriatic plaques were treated with the 3...
