Cultivating cultural capitals in introductory algebra-based physics through reflective journaling.

At a large, diverse, hispanic-serving, master's-granting university, the Alma Project was created to support the rich connections of life experiences of science, technology, engineering, and mathematics (STEM) students that come from racially diverse backgrounds through reflective journaling. Utilizing frameworks in ethnic studies and social psychology, the Alma Project aims to make learning STEM inclusive by affirming the intersectional identities and cultural wealth that students bring into STEM classrooms. Approximately once per month students who participate in the Alma Project spend 5-10 min at the beginning of class responding to questions designed to affirm their values and purpose for studying STEM in college.

[Idiopathic pulmonary hemosiderosis with dendriform pulmonary ossification].

Pulmonary ossification is a rare and usually asymptomatic finding reported as incidental in lung biopsies. Similarly, idiopathic pulmonary hemosiderosis is a rare cause of pulmonary infiltrates. We report the case of a 64-year old man with chronic respiratory symptoms in whom these two histopathological findings converged.

Microwave assisted extraction for the determination of ethyl glucuronide in urine by gas chromatography-mass spectrometry.

Alcohol is the most frequently abused 'addictive substance' that causes serious social problems throughout the world; thus alcoholism is of particular interest in clinical and forensic medicine. Ethyl glucuronide (EtG) is a marker of recent alcohol consumption that detects alcohol use reliably over a definite time period. The present paper describes a new method for the determination of EtG in urine.

Antimicrobial activity of nisin adsorbed to surfaces commonly used in the food industry.

The adsorption isotherms of nisin to three food contact surfaces, stainless steel, polyethyleneterephthalate (PET), and rubber at 8, 25, 40, and 60 degrees C, were calculated. For all surfaces, the increase in temperature led to a decrease in the affinity between nisin and the surface. The rubber adsorbed a higher amount of nisin (0.
