Simulation of piston and piston ring dynamics

, 2019
Piston group is the main contributor to friction with an amount of 40%-50% of the total IC engine friction. The market is looking for efficient friction reduction methods without drawbacks in durability and NVH. In light of this, efficient parameter studies and optimization processes in multibody dynamics simulation are becoming increasingly important ...

Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

Effects of flow‐controlled expiration on oxygenation and early recovery in horses undergoing general anaesthesia

Equine Veterinary Journal, EarlyView.
Abstract Background FLow‐controlled EXpiration (FLEX) has been shown to significantly enhance oxygenation in horses under clinical and experimental conditions. Objectives To compare pulmonary gas exchange during early recovery following general anaesthesia in horses ventilated with FLEX compared with conventional intermittent positive pressure ...

Warmed intravenous fluid administration attenuated a reduction in body temperature in anaesthetised horses

Equine Veterinary Journal, EarlyView.
Abstract Background Peri‐anaesthetic hypothermia is a well‐documented complication of general anaesthesia and is associated with prolonged recovery, impaired wound healing, and delayed coagulation. Fluid warmers can be used to mitigate heat loss, but there is little evidence supporting their effectiveness in equine anaesthesia.

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,
