Thermodynamic assessment of evaporation during molten steel testing onboard the International Space Station.

Evaporation control is a critical facility resource during solidification experiments that limits processing time and must be tracked to ensure facility health. A thermodynamic analysis was performed on a ternary FeCrNi sample processed onboard the International Space Station (ISS) using ESA Electromagnetic Levitation (EML) facility in a microgravity environment. A non-ideal solution-based mathematical model was applied for the overall sample mass loss prediction during this study.

Lean Six Sigma Methodologies to Reduce the Cardiac Troponin Turnaround Time in the Core Laboratory.

Objective: Measurement of cardiac biomarker troponin T plays a vital role in the diagnosis of myocardial infarction. A quick turnaround time (TAT) for cardiac troponin T is crucial in managing patients in the emergency department and critical care unit. The goal of the study was to implement Lean Six Sigma methods to improve stat troponin T TAT compliance rate (the time specimen received in the laboratory to the reporting of results through the laboratory information system [LIS]) from 86% to 95% in an 8-month period.

Isolated Metastasis to the Brain From Upper Tract Urothelial Carcinoma.

Isolated brain metastasis from cancers of urothelial origin are rare, especially after a long recurrence-free interval with few reports in the literature. We herein present the case of a 62 year old male with history of recurrent bladder cancers treated in 2004 and 2005 and a left distal ureteral high grade pT3aN1M0 urothelial cancer treated with distal ureterectomy and reimplant followed by adjuvant chemotherapy in 2014 who presented after a 5 year recurrence-free interval with tonic-clonic seizure. Further workup revealed an isolated 12.

Acute abdomen with bones in the spleen.

Introduction: A 28-year old female presented with a non-radiating persistent left upper quadrant pain and tenderness for 5 weeks.

Methods: A preliminary CT scan displayed bony structures in the spleen. A delayed scanning subsequently showed the bones to have changed position, consistent with a life fetus.
