Least dilatation of pure surface braids
… classes is a unique algebraic number called its dilatation or ``stretch-factor"". In this thesis, we build on work of Penner who introduced the study of the minimal dilatation of pseudo-Anosovs in subgroups of the mapping class group. We prove upper and lower bounds on the minimal dilatation of …

Continuous measurement of cervical dilatation during labour
… for the continuous measurement of cervical dilatation is described. The principle of operation, being that of mutual inductance, utilises two coils, one on the posterior lip of the cervix and the other on the anterior, the axes of these coils being kept parallel by a flexible linkage. A …

Ballon-Dilatation subglottischer Stenosen insbesondere bei Granulomatose mit Polyangiitis
… Zudem wurde die Anzahl der notwendigen Ballondilatationen dokumentiert, der Stenosegrad gemessen und nach Myer Cotton bestimmt. Ergebnisse Vier PatientInnen, die nur eine Intervention mit dem Ballon benötigten, zeigten eine bessere präinterventionelle Atemfunktion sowie eine höhere subjektive …

Low dilatation pseudo-anosovs on punctured surfaces and volume
For a pseudo-Anosov homeomorphism f on a closed surface of genus g greater of equals to 2, for which the entropy is on the order 1/g (the lowest possible order), Farb-Leininger-Margalit showed that the volume of the mapping torus is bounded, independent of g. We show that the analogous result fails …

Pneumatic balloon dilatation versus laparoscopic Heller's myotomy in idiopathic achalasia
… Heller's myotomy (LHM) and pneumatic balloon dilatation (PBD) are widely used in the management of achalasia, but there is still no clarity as to which of these interventions is the best treatment for patients with the condition. Methods Newly diagnosed achalasia patients were randomised into …

Intra-operative Prophylactic Pyloric Balloon Dilatation During Oesophagectomy to Prevent Early Delayed Gastric Emptying
… anastomotic leak and pneumonia. Pyloric balloon dilatation (PBD) is a recognised treatment of this complication. Preventative measures such as pyloroplasty, pyloromyotomy and pyloric Botox® injection have all been employed. Recent data however suggest none of these treatments have a significant …

Prescribing Dilatations in Space
On this domain, we define the dilatation from the transformation matrix A = UDVT of an affine mapping in R3 . Let B = ATA = VD2VT = [ bij]. Define the dilatation m&ar; as m&ar;=1M b11b22-b2 12 b11b33-b2 13 b22b33-b2 23 , where M2 = b 11b22 -- b212 + b11b33 -- b213 + b22b33 -- b223 + lambda (det …

ΣΥΜΒΟΛΗ ΕΙΣ ΤΗΝ ΜΕΛΕΤΗΝ ΤΗΣ ΟΞΕΙΑΣ ΓΑΣΤΡΙΚΗΣ ΔΙΑΤΑΣΕΩΣ
ACUTE GASTRIC DILATATION IS MAINLY A POSTOPERATIVE COMPLICATION. THE PRESENT STUDY AIMS AT THE INVESTIGATION OF THOSE FACTORS WHICH CONTRIBUTE TO THE DEVELOPMENT OF ACUTE GASTRIC DILATATION AND OF THE ESTABLISHMENT OF THOSE PROOPERATIVE, OPERATIVE AND POSTOPERATIVE MEASURES, WHICH DIMINISH THE …

The performance of cross-linked acellular arterial scaffolds as vascular grafts; pre-clinical testing in direct and isolation loop circulatory models
… off-the-shelf grafts resistant to thrombosis, dilatation and calcification. To test this hypothesis, we decellularized porcine renal arteries, stabilized elastin with pentagalloyl glucose and collagen with carbodiimide/activated heparin and implanted them as trans- position grafts in the …

Delayed gastric emptying in Ivor Lewis Gastro-oesophagectomy
… DGE patients had repeated test after pyloric dilatation. Analyses of gut hormones(GH): glucagon-like-peptide-1(GLP-1) and peptide tyrosine tyrosine(PYY), were conducted based on DGE status and treatment. Post-operative DGE-related symptoms(PODRS) were assessed using a modified questionnaire. …
