The global demand for ultralow-temperature (ULT) refrigeration units gets greatly promoted, for storage, transportation, and distribution of COVID-19 vaccines. In this work, a ULT freezer is developed with a cascade refrigeration system (CRS) utilizing environmentally friendly refrigerants R290 and R170. The performance of the ULT freezer is experimentally evaluated under different ambient tempera
The taxonomy, diversity, evolutionary lineages, and stratigraphical distributions of Middle and early Late Triassic conodonts are reviewed and re-evaluated. Twenty-five genera are recognized in the Middle and early Late Triassic, including a new genus cited in open nomenclature. Of these, 24 genera are assigned to two families and seven subfamilies. The family Gondolellidae consists of the subfami
Pedestrian dynamics is concerned with understanding the movement patterns that arise in places where more than one person walks. Relating theoretical models to data is a crucial goal of research in this field. Statistical model fitting and model selection are a suitable approach to this problem and here we review the concepts and literature related to this methodology in the context of pedestrian
Among the numerous point vapor sources, microsecond-pulsed spark ablation at atmospheric pressure is a versatile and environmentally friendly method for producing ultrapure inorganic nanoparticles ranging from singlets having sizes smaller than 1 nm to larger agglomerated structures. Due to its fast quenching and extremely high supersaturation, coagulational growth already begins at the atomic sca
Drug abuse became a big social problem in Sweden during the 1960’s when the youth’s use of narcotics started to expand. The Swedish drug policy stands for total prohibition. All thing related to narcotics are illegal, to use, to smuggle, to produce, to hold and to buy. The aim of this study was to examine the Swedish drug policy and to examine how the members of the internet forum Flashback discus
This thesis studies hallandic hillforts through both field research and computer analysis. The research questions concern morphology, classification, cultural landscape, and regional variation. The purpose of this thesis is to create a more developed and nuanced image of the hill forts, starting by mentioning them as enclosures (hägnadsanläggning) instead of hill fort (fornborg). By dividing the e
Cluttering is a fundamental problem in 3D city model visualization. In this paper, a novel method for removing cluttering by typification of linear building groups is proposed. This method works. in static as well as dynamic visualization of 3D city models. The method starts by converting building models in higher Levels of Details (LoDs) into LoD1 with ground plan and height. Then the Minimum Spa
The role of informal venture capital in entrepreneurial process and economic development is increasingly recognized by scholars and policy-makers around the world. Much of the attention that this form of financing has received during the last couple of decades is due to its potential to bridge the regional equity gap. This study is concerned with regional distribution of informal venture capital a
Popular Abstract in Swedish Ägglavarna, släktet Candelariella, är ett relativt litet släkte omfattande ungefär 50 kända arter i världen. Släktet är ansett som en problematisk grupp med få karaktärer som är användbara för att skilja arterna åt. Enbart ett fåtal studier har tidigare behandlat arterna och den mest omfattande är en avhandling av Rainar Hakulinen från 1954, vilken i första hand behandlThe lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated. Nine new species are proposed and in total twenty-one species are recognized from the region
The European Society of Organ Transplantation (ESOT) strives to promote equity, diversity, and inclusion (EDI) across all its activities. We surveyed the transplant community’s experiences and perspectives regarding EDI within ESOT as an organization and its educational activities, and research in general. A total of 299 respondents completed the questionnaire. About half agreed that ESOT’s Execut
Starting from the premise that English negative modal contractions constitute partly variable patterns of associations that include both the preceding subject and the following verb infinitive, the study sets out to investigate distributional differences between can’t, shouldn’t, and won’t and their corresponding uncontracted parent forms. Given that some configurations are assumed to correlate wi
We performed a comprehensive study of the charge carrier diffusion in the CsMAFA perovskite, one of the state-of-the-art perovskites for photovoltaic applications, starting from the diffusion of hot carriers to the eventual trapping at the surfaces and grain boundaries. We discovered evidence of non-ambipolar diffusion by using ultrafast transient reflectance spectroscopy: by comparing the transie

Popular Abstract in Swedish Nygjuten betong innehåller överskottsfukt som avges till omgivningen under uttorkningen. Om uttorkningen får fortsätta i en konstant luftfuktighet antar betongen så småningom samma fuktighet. Eftersom betong är ett tätt material tar det lång tid, ofta flera år, innan så har skett. Tills detta har inträffat sker en fukttransport från de inre delarna ut till ytan. En delThere were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. Residual moisture in screeded concrete slabs may be redistrib
