Experimental setup for labyrinth seals: Pressure, temperature, mass flow rate, rotation velocity, and pressure drop simultaneous measurement.

Labyrinth seals (LSs) in turbomachinery are used to minimize leaks. This study presents an experimental setup designed to test and validate LS designs. The test bench (TB) described in this paper can evaluate different LS designs obtained through various methods to find better solutions to mitigate greenhouse gas (GHG) emissions.

Late-onset vitamin K deficiency presenting as haemorrhagic shock and severe multi-system organ failure.

Vitamin K is an essential dietary cofactor required for the synthesis of active forms of vitamin K-dependent procoagulant proteins. Vitamin K deficiency, particularly late-onset deficiency occurring between 1 week and 6 months of age, can cause a life-threatening bleeding disorder. An exclusively breastfed, full-term, 6-week-old infant male presented with severe haemorrhagic shock and multi-system organ failure related to caregiver refusal of intramuscular vitamin K after birth.

The Effects of Hospital-Based School Lessons on Children's Emotions, Distress and Pain.

Lessons conducted in hospitals ensure school continuity for hospitalized children unable to attend regular school. Hospital-based school (HS) provides a tailored experience that ensures normality for children through education. The objective of this study is to evaluate the effects of the proposed lessons in reducing negative emotions, distress, and pain in children, as well as fostering positive affects.

Camera trap surveys of Atlantic Forest mammals: A data set for analyses considering imperfect detection (2004-2020).

Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land-cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity hotspot, especially for medium to large-sized species.
