AIMS To determine the long-term (20 years from presentation) outcome of brittle type 1 diabetes characterized by recurrent episodes of ketoacidosis (DKA). METHODS The cohort studied was a group of brittle diabetic patients from various parts of UK originally identified between 1979 and 1985. Patients were traced, where possible, via their diabetic clinics and/or general practitioners. Data on...

the new non-conventional cutting process by the use of thermal shock is a convenient procedure for cutting the brittle materials such as glasses and ceramics. this method is based on the application of localized thermal shock to brittle materials by the use of hot air jet, which induces thermal stresses at the tip of an existed pre-crack. due to the thermo-elastic behavior of materials, the pre...

Owing to a lack of microstructure, glassy materials are inherently strong but brittle, and often demonstrate extreme sensitivity to flaws. Accordingly, their macroscopic failure is often not initiated by plastic yielding, and almost always terminated by brittle fracture. Unlike conventional brittle glasses, metallic glasses are generally capable of limited plastic yielding by shear-band sliding...

We used sea floor photography to estimate brittle star abundance in Young Sound, NE Greenland and the adjacent shelf. From photos covering a total area of 78 m2 and spanning a depth range from 20 to 310 m we found maximum average densities of >400 ind. m–2 at 40 to 80 m depth. Ophiocten sericeum was the dominant species. However, gradual changes in species and size composition with depth were o...

BACKGROUND The aim was to describe the prevalence and characteristics of difficult to manage dyskinesia associated with subthalamic nucleus (STN) deep brain stimulation (DBS). A small subset of STN DBS patients experience troublesome dyskinesia despite optimal programming and medication adjustments. This group of patients has been referred to by some practitioners as brittle STN DBS-induced dys...

We propose a new model for the brittle-to-ductile transition based on the Kosterlitz-Thouless concept of dislocation screening. In this model, thermal fluctuations assisted by the applied stress drive the spontaneous generation of dislocations and the instability occurs well below the melting temperature. In the limit of zero stress, our model reduces to the Kosterlitz-Thouless theory of the me...

There are numerous and important coral reefs in the Mexican Pacific, but scarce studies of brittle stars conducted in these ecosystems. In this regard, this work provides the first annotated checklist of brittle stars associated with coral communities and reefs in the Mexican Pacific and an illustrated key to identify the species. We also provide taxonomic descriptions, spatial and bathymetric ...
