The propagation of spiral waves in two-dimensional reactive–diffusive media subject to a velocity field with straining is studied numerically. It is shown that, depending on the magnitude of the strain rate, the effects of straining on wave propagation can be classified in three regimes: the no break-up, the transitional and the break-up regimes. In the no break-up regime, the spiral wave prese...

OBJECTIVE To evaluate a multidisciplinary Hong Kong treatment programme for patients with constipation. DESIGN Pilot study. SETTING A joint collaboration among the departments of surgery, physiotherapy, and dietetics in a regional hospital in Hong Kong. PATIENTS Thirty-one constipated patients with normal colonic transit and pelvic floor dyssynergia. INTERVENTION Multidisciplinary treat...

A full termed local ewe with the history of continuous straining with labored breathing for last 24 hours was presented. The animal was disinclined to move with tense and round abdomen which developed rapidly during last two weeks. Caesarean section revealed hydrallantois accompanied by multiple fetal congenital abnormalities. The ewe was under observation for four weeks. Metritis developed 12 ...

the historical documents are the important traces of the history. Historical documents carry the information about the tradition, religion, science, literature, war strategies of the ancient times, which are very useful to understand the life and culture of the ancient civilizations. These historical documents are usually recovered from the archaeological findings. Historical documents are usua...

This paper studies the effects of frequency, pre-strain and electrode types on the dielectric property of a commercially available and most widely used acrylic elastomer, VHB 4910. The acrylic VHB film is pre-stretched in biaxial directions with the help of an in-house developed biaxial stretching device. The stretched film has been sandwiched between two card board frames to prepare samples of...

The present work is focused on a comparative study of the effect Ti-Al interlayers and Ta alloying mechanical behavior Ti1−xAlxN coatings under normal contact pressure in-plane straining. loading samples was carried out by scratch testing, while tensile straining performed uniaxial tension coated steel substrates. Ti0.45Al0.55N Ti0.43Al0.45Ta0.12N monolithic as well Ti0.45Al0.55N/Ti0.45Al0.55 m...

the focus of this study was to determine if early detection of mutant p53 accumulation may be an early indicator of tumor aggressiveness and transformation to invasive breast cancer. for this purpose, the p53 content of 100 human breast biopsies classified as ductal carcinoma (dcis), was evaluated by immunohistochemical method. all specimens were microscopically classified into histologic types...
