Evaluation of residual stress in the weld toe region is of critical importance. In this paper, the residual stress distribution both near the surface and in depth around the weld toe was investigated using neutron diffraction, complemented with X-ray diffraction. Measurements were done on a 1300 MPa yield strength steel welded using a Low Transformation Temperature (LTT) consumable. Near surfac...

Laser tonsillotomy (LTT) represents a useful, less invasive alternative to tonsillectomy as a treatment for symptomatic tonsillar hyperplasia in children, and is associated with greatly reduced risks. The main characteristics that distinguish this procedure from tonsillectomy are a significantly reduced risk of secondary bleeding, a shorter recovery, reduced pain and the fact that it can be per...

IFN-a: interferon alfa LTT: lymphocyte transportation test TNF-a: tumor necrosis factorealfa T umor necrosis factor alfa (TNF-a) antagonists are commonly used to treat inflammatory disorders and are considered particularly effective in the treatment of moderate to severe psoriasis. Paradoxically, however, new-onset occurrence orworsening of psoriasis has been increasingly recognized among patie...

The paper proposes a new method of linear text segmentation based on lexical cohesion of a text. Namely, first a single chain of disambiguated words in a text is established, then the rips of this single chain are considered as boundaries for the segments of the cohesion text structure (Cohesion TextTiling or CTT). The summaries of arbitrarily length are obtained by extraction using three diffe...

A logic-enriched type theory (LTT) is a type theory extended with a primitive mechanism for forming and proving propositions. We construct two LTTs, named LTT0 and LTT ∗ 0, which we claim correspond closely to the classical predicative systems of second order arithmetic ACA0 and ACA. We justify this claim by translating each second-order system into the corresponding LTT, and proving that these...

OBJECTIVES Chronic low-level metal exposure may result in metal sensitization and undesirable side-effects. The main sources of metal exposure are from the environment or from corrosion of dental metal alloys. Affected patients are routinely diagnosed with the epicutaneous (patch) test. However, such testing may induce false-positive (irritative) reactions and may in itself sensitize or exacerb...

BACKGROUND Heart failure is a common complication of diabetes characterized by an elevation in left ventricular filling pressures (LVF) that often develops in the absence of clinical symptoms. Diastolic dysfunction in the setting of low total testosterone (LTT) occurs through changes in the regulation of peripheral hemodynamics. LTT is highly prevalent among individuals with type 2 diabetes. Th...

This study is a synthesis between experimental work and theoretical modelling aiming to understand the mechanism of the sub-threshold oscillations (STOs) observed in the neurons of the inferior olive (IO) nucleus. The model was constructed in a bottom-up approach: it started from the construction of a detailed model of physiologically and morphologically reconstructed IO neurons, progressed to ...

We present a series of detailed band calculations on the various structural phases of doped lanthanum cuprate: HTT, LTO, and LTT. The LTO distortion is shown to have little effect on the electronic density of states (DOS). A fit to the pressure dependence of the superconducting transition temperature indicates that only 2.5% of the DOS is affected by the HTT→ LTO transition. The LTT distortion ...
