We document trends in affective polarization during the coronavirus pandemic. In our main measure, is relatively flat between July 2019 and February 2020, then falls significantly around onset of Three five other data sources display a similar downward trend, with two showing no significant change. A survey experiment shows that priming respondents to think about pandemic reduces polarization.

As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact with crude oil and is co-produced with it as well. Considering that asphaltene molecules are pol...

In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...

One hundred patients with chronic airway obstruction, 50 in Chicago and 50 in London, were studied by standardized techniques in 1961. The results of the initial studies, previously reported, showed that the patients in the two cities were similar; using clinical and physiological criteria based on pathological studies, the patients were divided into three types-emphysematous type A, bronchial ...

Introduction: Raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. The aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging. Materials and Methods: In this descriptive study, the facial CT scans were obta...

Four cases of polyarthritis concomitant with active tuberculosis is reported. In three patients pulmonary tuberculosis was confirmed by identification of Mycobacterium tuberculosis in the sputum and bronchoalveolar lavage specimens, and in another one tuberculous lymphadenitis was confirmed by excisional biopsy. In all patients arthritis resolved by tuberculosis treatment and did not recur ...
