Existence theory for nonresonant singular boundary value problems
(Cambridge University Press (CUP), 1995-10-01)
We present some existence results for the ''nonresonant'' singular boundary value problem 1/pq(py')'+ mu y = f(t, y) a.e. on [0,1] with lim(t-->0) + p(t)y'(t)=y(1)=0. Here mu is such that 1/pq(pu')'+mu u=0 a.e. on [0,1] ...
Altered thermoregulatory responses to clonidine in streptozotocin-diabetic rats
1 The effects of streptozotocin (STZ) treatment on alpha(2)-adrenoceptor regulation of body temperature were studied by monitoring the response of colonic temperature to administration of clonidine. 2 A dose-dependent fall ...
Resonant singular boundary value problems
(Rocky Mountain Mathematics Consortium, 1995-12-01)
Existence theory is developed for the ''resonant'' singular problem (1/(pq))(py')' + lambda(0)y = f(t,y,py') almost everywhere on [0, 1] with lim(t-->0+) p(t)y'(t) = ay(1) + blim(t-->1-) p(t)y'(t) = 0. Here lambda(0) ...
Neuroendocrine response to clonidine and 8-oh-dpat in rats following chronic administration of desipramine or sertraline
1 Rats were administered either desipramine (DMI) or sertraline daily at doses 7.5 mg kg-1 or 10 mg kg-1, i.p., respectively and the effects on the functional state of hypothalamic neuroendocrine control mechanisms assessed ...
Existence theorems for certain classes of singular boundary value problems

An evaluation of preoperative ca 15-3 measurement in primary breast carcinoma
(Springer Nature, 1995-06-01)
In this study of 500 patients with breast carcinoma, we have prospectively assessed the role of preoperative CA 15-3 as a marker of disease burden over a 7 year period. CA 15-3 levels at presentation correlate with stage ...
Preparation of imidazo[1,2-c]pyrimidinones from a chloropyrimidine and an electron poor ω-allylic amine
(Royal Society of Chemistry (RSC), 1998-01-01)
Synthesis of the title ring system by a sequential intermolecular nucleophilic displacement and intramolecular 'conjugate' addition has been achieved both as a one pot and as a stepwise procedure; an X-ray structure ...
The influence of operator changes on orthodontic treatment times and results in a postgraduate teaching environment
(Oxford University Press (OUP), 1998-04-01)
There is some concern that patients treated by postgraduate students during their speciality training may be disadvantaged in the quality of treatment result and subject to longer treatment times if they are treated by ...
A germline taqi restriction fragment length polymorphism in the progesterone receptor gene in ovarian carcinoma
(Springer Nature, 1995-03-01)
Clinical outcome in ovarian carcinoma is predicted by progesterone receptor status, indicating an endocrine aspect to this disease. Peripheral leucocyte genomic DNAs were obtained from 41 patients with primary ovarian ...
