Effect of Perineal Urethrostomy on the Length of the Urethra of the Cat: A Cadaveric Study

open access: yesAnimals, 2023
Perineal urethrostomy in cats is indicated for urethral pathologies located distal to the bulbourethral glands. The description of the bulbourethral glands as the cranial landmark when performing a PU is based on the increased urethral diameter at this ...

Study of the passage of low-frequency ultrasonic vibrations through heterogeneous biological media during ultrasonic sanitation of urological catheters [PDF]

open access: yesОмский научный вестник, 2022
The purpose of this article is to study the features of the passage of ultrasonic vibrations through inhomogeneous biological media. To achieve the goal, a mathematical model for the propagation of ultrasonic vibrations in heterogeneous media has been

Influence of Gradually Inflated Obstructions on Flame Propagation in a Tube Closed at One End

open access: yesFire, 2023
Rapid suppression is a must in the mitigation of ventilation air methane (VAM) explosions. Flame suppression proves to be much more challenging than prevention of flame initiation due to the small physics timescale (~1 s).

Improving the efficiency of sanitation of urological catheters with various types of exposure to ultrasound emitters [PDF]

open access: yesОмский научный вестник, 2022
The purpose of the article is to determine rational modes for safe and effective ultrasound exposure in order to sanitation urological catheters. It is shown that using an amplitude-modulated or pulsed power supply mode, it is possible to achieve an ...

Gastric outlet obstruction from duodenal lipoma in an adult

open access: yesNigerian Journal of Surgery, 2013
The duodenum is a rare site for gastrointestinal lipoma with less than 230 cases reported in the literature. Although, peptic ulcer disease remains the most common benign cause of gastric outlet obstruction (GOO), duodenal lipomas remain a rare, but ...

The age grading and the Chen-Ruan cup product [PDF]

open access: yes, 2008
We prove that the obstruction bundle used to define the cup-product in Chen-Ruan cohomology is determined by the so-called `age grading' or `degree-shifting numbers'. Indeed, the obstruction bundle can be directly computed using the age grading.

Antegrade pressure measurement of urinary tract in children with persistent hydronephrosis

open access: yesInternational Brazilian Journal of Urology, 2012
INTRODUCTION: Dilation of urinary tract occurs without the presence of obstruction. Diagnostic methods that depend on renal function may elicit mistaken diagnosis.

Gastric transcatheter chemoembolization can resolve advanced gastric cancer presenting with obstruction

open access: yesFrontiers in Surgery, 2022
BackgroundGastric transcatheter chemoembolization (GTC) is an interventional minimal invasive method, which has never been mentioned in the previous literature for advanced gastric cancer with obstruction.

Comparing descent obstruction and Brauer-Manin obstruction for open varieties

open access: yes, 2018
We provide a relation between Brauer-Manin obstruction and descent obstruction for torsors over open varieties under a connected linear algebraic group or a group of multiplicative type is given.

A slicing obstruction from the 10/8 theorem [PDF]

open access: yes, 2016
From Furuta's $\frac{10}{8}$ theorem, we derive a smooth slicing obstruction for knots in $S^3$ using a spin $4$-manifold whose boundary is $0$-surgery on a knot.
