OBJECTIVE To evaluate the behavior of oxygen saturation curves throughout the six-minute walk test (6MWT) in patients with COPD. METHODS We included 85 patients, all of whom underwent spirometry and were classified as having moderate COPD (modCOPD, n = 30) or severe COPD (sevCOPD, n = 55). All of the patients performed a 6MWT, in a 27-m corridor with continuous SpO2 and HR monitoring by telem...

BACKGROUND Endoscopic ultrasonography (EUS) is a valuable imaging tool for evaluating subepithelial lesions in the stomach. However, there are few studies on differentiation between gastrointestinal stromal tumors (GISTs) and benign mesenchymal tumors, such as leiomyoma or schwannoma, with the use of EUS. In addition, there are limitations in the analysis of the characteristic features of such ...

Temperature rise is a concern for future agriculture in different regions of the globe. This study aimed to reveal changes and variabilities minimum temperature (Tmin) maximum (Tmax) monthly, seasonal, annual scale over Bangladesh using 40 General Circulation Models (GCMs) Coupled Model Intercomparison Project Phase 5 (CMIP5) two radiative concentration pathways (RCPs, RCP4.5 RCP8.5). The stati...

The primary objective of the paper was to characterize climatic conditions in winter season Poland years 1966/67–2019/20. study based on daily values minimum (Tmin) and maximum air temperature (Tmax), snow cover depth. showed an increase both Tmin Tmax winter. most intensive changes were recorded north-eastern northern regions. coldest winters first half analyzed multiannual period, exceptional...

A statistical model based on canonical correlation analysis (CCA) was used to explore climatic associations and predictability of June–August (JJA) maximum and minimum surface air temperatures (Tmax and Tmin) as well as the frequency of Tmax daily extremes (Tmax90) in the central and western United States (west of 90°W). Explanatory variables are monthly and seasonal Pacific Ocean SST (PSST) an...

Self-pierce riveting (SPR) is a major joining method used in the automotive industry. However, there still lacks fast and easy-to-use joint quality prediction tool available for engineers. In this study, simple but effective regression analysis was applied to quickly predict SPR quality. Two models were developed of interlock minimum remaining bottom sheet thickness (Tmin). The accuracy validat...

Trends in seasonal mean values of maximum and minimum temperature are analysed the Spanish mainland from new MOTEDAS_century database. This data set has been developed combining digitalized archives Meteorological Agency (AEMET) with information retrieved Annual Books published by former dating back to 1916, covers period 1916–2015. In all four seasons, (Tmax) (Tmin) increased. The raising occu...

The extreme temperature has become more frequent and intense due to global warming, particularly in dry regions, causing devastating impacts on humans ecosystems. transboundary Amu river basin (ARB) is the most vulnerable region Central Asia (CA) weather linked climate change. This study aimed project warm cold extremes ARB for four Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0 SS...

Records from 7 studies conducted during 1999 to 2005 were utilized to assess the effects of environmental factors on daily water intake (DWI) of finishing cattle. Data from unshaded feedlot pens (up to 24 pens utilized per study; 6 to 9 animals·pen(-1)) containing predominantly Angus crossbred cattle were obtained by dividing total water intake by the number of animals utilizing that waterer. E...
