The impact of the Covid-19 pandemic on college students with marginalized identities.

This study sought to examine whether college students with marginalized identities have been disparately impacted by the Covid-19 pandemic with regard to perceived stress, social isolation, and pandemic-related concern, and whether this relationship was moderated by self-reported experiences of prejudice and/or discrimination. Nine hundred eighty three college students from 38 of the United States completed an online survey. Results showed that college students who were born after 1997 (i.

Understanding how college students characterise and cope with chronic pain: a thematic analysis of expressive writing samples.

College students who experience chronic pain are a frequently overlooked population. This research attempts to provide insight into the language that college students use to describe their experiences with chronic pain, challenges they face and coping strategies they use. Over the course of 4 consecutive days, participants responded to an expressive writing prompt asking them to reflect on their emotions and thoughts related to being a college student with chronic pain.

Young adults' stigmatizing perceptions about individuals with skin cancer: the influence of potential cancer cause, cancer metaphors, and gender.

This study examined the influence of three potential predictors of stigmatising cancer perceptions: the controllability of the cancer cause, metaphors used to describe the cancer experience, and the target's gender. 306 undergraduates (age = 20) were recruited via subject pool, balancing males and females. Participants read a fictitious post by a patient/blogger with skin cancer that described different potential causes for their cancer varying with respect to its controllability, used varying types of commonly invoked cancer metaphors, and indicated their gender with names.

Direct Measurements of the Volume Flow Rate and Emissions in a Large Naturally Ventilated Building.

The direct measurement of emissions from naturally ventilated dairy barns is challenging due to their large openings and the turbulent and unsteady airflow at the inlets and outlets. The aim of this study was to quantify the impacts of the number and positions of sensors on the estimation of volume flow rate and emissions. High resolution measurements of a naturally ventilated scaled building model in an atmospheric boundary layer wind tunnel were done.

Impact of roof height non-uniformity on pollutant transport between a street canyon and intersections.

This paper presents an extension of our previous wind-tunnel study (Nosek et al., 2016) in which we highlighted the need for investigation of the removal mechanisms of traffic pollution from all openings of a 3D street canyon. The extension represents the pollution flux (turbulent and advective) measurements at the lateral openings of three different 3D street canyons for the winds perpendicular and oblique to the along-canyon axis.

Wind tunnel measurement of turbulent and advective scalar fluxes: a case study on intersection ventilation.

The objective of this study is to determine processes of pollution ventilation in the X-shaped street intersection in an idealized symmetric urban area for the changing approach flow direction. A unique experimental setup for simultaneous wind tunnel measurement of the flow velocity and the tracer gas concentration in a high temporal resolution is assembled. Advective horizontal and vertical scalar fluxes are computed from averaged measured velocity and concentration data within the street intersection.

Esophageal prosthesis and its most common complications.

Plastic prostheses of our own modification introduced under endoscopic control, have been successfully used in 46 patients with advanced malignant or scarred stenosis of the esophagus. Despite maximum care, their introduction is associated with a certain risk of complications and incidents. In our series, the introduction of a prosthesis was complicated by perforation of the canceromatous esophageal wall in 2 patients (0.

[Indications and limitations of esophagoscopy with flexible fiberoptics (author's transl)].

The authors evaluate the results of 241 diagnostic esophagoscopies with fiberoptics performed in the years 1973/74. The fiberoptics were successfully used in 208 patients (86%) suffering of inflammatory processes of the esophagus, hiatus hernias, carcinomas and spontaneous or traumatic bleeding of the esophagus. In 33 cases (14%) the fiberoptics were not sufficient in establishing a diagnosis and had to be followed by a classical esophagoscopy.
