Atmospheric gravity waves (GWs) perturb minor species involved in the chemical reactions of airglow emissions in the mesopause region of the earth's atmosphere. The so-called 'Cancellation Factor' (CF) is defined as a transfer function relating the amplitude of airglow brightness fluctuation to the amplitude of GW-induced fluctuation in temperature [Swenson and Gardner, 1998]. This transfer fac...

TO THE EDITOR: We followed with great interest the recent exchanges between Drs. Teppema and Berendsen (4) on one hand and Dr. Swenson on the other hand regarding the mechanisms of effects of acetazolamide (AZ) in the prevention of Acute Mountain Sickness (AMS) (3). One of the essential questions raised by both parts is the action of AZ on central and peripheral chemosensitivity, respectively. ...

Objective To investigate different outcomes and long-term efficacy of transanal Soave or Swenson surgery in treatment for neonates with Hirschsprung's disease (HD). Methods In the present study, a total of 29 neonatal patients were included, with 20 patients undergoing the Soave procedure and nine patients undergoing the Swenson procedure. Data collected from the patients included basic demog...

CONTEXT Swenson's pull-through is one of the standard operations for the treatment of children with Hirschsprung's disease. Complications arising from the operation are difficult to treat because of fibrosis in the pelvis. The posterior sagittal approach may be a safer alternative. AIMS The aim of this paper is to highlight our experience with the use of the posterior sagittal trans-sphincter...

In 1959 Swenson and Rathauser described three patients with an unusual dilatation of the colon. Each case had been referred to the hospital with a diagnosis of Hirschsprung's disease (congenital aganglionic megacolon), and on the whole the histories were consistent with this diagnosis. Histological examination of a pre-operative rectal biopsy specimen and a specimen taken during operation, howe...

Susceptibility to diseases of economically important grapes is critical the evaluation germplasm recommended for commercial production and development sustainable systems. In 2018–2019, cold-hardy grape cultivars including ‘Brianna’, ‘Crimson Pearl’, ‘Itasca’, ‘Louise Swenson’, ‘Marechal Foch’, ‘Marquette’ ‘Petite ‘St. Pepin’, ‘Verona’ were evaluated on non-treated vines susceptibility downy mi...
