Transport of Antarctic stratospheric strongly dehydrated air into the troposphere observed during the HALO-ESMVal campaign 2012
2015
Abstract. Dehydration in the Antarctic winter stratosphere is a well-known phenomenon that is annually observed by satellites and occasionally observed by balloon-borne measurements. However, in situ measurements of dehydrated air masses in the Antarctic vortex are very rare. Here, we present detailed observations with the in situ and GLORIA remote sensing instrument payload aboard the German aircraft HALO. Strongly dehydrated air masses down to 1.6 ppmv of water vapor were observed as far north as 47° S in an altitude between 12 and 13 km in the lowermost stratosphere. The dehydration can be traced back to individual ice formation events above the Antarctic Peninsula and Plateau, where ice…
Skolotāja valoda angļu valodas stundās pozitīvu attiecību veidošanai klasē
2017
Pētījums aplūko kā skolotāju klases valoda palīdz veidot pozitīvas savstarpējās attiecības klasē, jo pozitīvai atmosfērai klasē ir nozīmīga loma svešvalodu apguvē. Aptaujā – pētījumā tika izmantotas šādas datu ieguves metodes: anketas piekto līdz divpadsmito klašu skolēniem, angļu valodas stundu novērošanas pieraksti, intervijas ar angļu valodas skolotājiem. Iegūtie dati atklāj skolēnu viedokli par angļu valodas skolotājiem un angļu valodas stundām, norādot, ka skolotājiem ir nepieciešams vairāk domāt par visu skolēnu iesaistīšanu mācību stundā, skolotāja lietotās valodas sarežģītību un runas ātrumu, kā arī vienādu attieksmi pret visiem skolēniem. Novērojot angļu valodas stundas, autore pie…
Priming effect increases with depth in a boreal forest soil
2016
Abstract Climate warming increases labile carbon (C) inputs to soil through increased photosynthesis and C allocation belowground. This could counterintuitively lead to losses of soil C via priming effects (PE): the stimulation of soil organic matter (SOM) decomposition caused by labile C addition. Systematic quantification of PEs in different ecosystems is needed. We measured PEs of free-living soil microbes in different layers of a boreal forest soil, and found that the relative magnitude of the PE increased with soil depth. The relationship between relative PE and the added glucose amount also depended on the soil layer. Our results indicate that the decomposition of SOM in deeper soil l…
Closed tank pneumatic press application to improve Sauvignon Blanc wine quality and nutraceutical properties
2019
The machines used in the winemaking process directly affect the quality of wine and its nutraceutical properties. Grapes-pressing is a very important step in winemaking as it may promote the presence and/or absence of enzymatic processes on the must, leading to the creation of different products in terms of chemical composition, starting from the same grapes. The aim of the study was to compare two different pressing systems of Sauvignon Blanc grapes using an innovative pneumatic discontinuous closed tank press in two operating modes: the traditional pressing mode in presence of oxygen and the inert pressing mode, performed through grapes pressing under inert gas with nitrogen recovery. Che…

'I Show Off, Therefore I Am': The Politics of the Selfie
2016
International audience; Named word of the year by the OED in 2013, the “selfie” is a worldwide phenomenon. Many see these digital self-portraits as markers for the spread of narcissism or signs of the blurring of limits between the public and private spheres. Initially popular with young people, selfies were soon adopted by politicians who, in a mediatized society, are eager to adhere to new vogues and use digital trends to self-promote. Like “digital natives”, they attempt to go viral by turning their cellphones on themselves and tweeting. Contrary to more formal images (official portraits, campaign posters) where politicians are clearly packaged and marketed, self-snapped photos taken on …
Florence Nightingale as a Victorian career woman
2016
The chapter focuses on the role of Florence Nightingale (1820-1910) in turning nursing into a trained profession and a viable and respectable career option for Victorian women seeking employment outside of the home. Nightingale's accomplishments and her thoughts on women's lot in life as expressed in her essay "Cassandra", are presented against the backdrop of the ideology of separate spheres which circumscribes women within the domestic domain. The chapter discusses Nightingale's work in British military field hospitals during the Crimean War, her successful efforts to reform the ways in which such hospitals were run, and the establishment of the Nightingale School and Home for Nurses and …
