The title Diels-Alder reaction gave a mixture of enantiomerically pure adducts with complete norbornane-type monoterpene skeletons. The exo/endo ratio of the products changed from approximately 4:1 at 5° to 2:1 at 165°
PEPCRE is an interactive computer graphics program for the rapid construction, manipulation and display of oligopeptides. Essentially any desired conformation of an oligopeptide can be constructed in a simple and straightforward manner. The program provides various display and output possibilities. It is user-friendly and is written in FORTRAN 77 for use on inexpensive, monochrome graphics termina
The 2-deoxy (7), 6-O-methyl (15), 6-deoxy (22), and 6-deoxy-6-fluoro (31) derivatives of methyl β-d-galabioside (1) have been synthesised. Thus, 7 was prepared by xanthate reduction using tributyltin hydride, whereas 22 was obtained by catalytic hydrogenation of a 6-deoxy-6-iodogalabioside. Regioselective mono-fluorination of methyl 2,3-di-O-benzoyl-β-d-galactopyranoside with Et2NSF3 and subsequen
Two new furanocembranoid diterpenes, crematofuran [(1R∗,11R∗,12R∗)-6,19:11,12-bisepoxycembra-3,6,8(19),15-tetraene] (1) and isocrematofuran [(1R∗,3S∗,4S∗)-3,4:6,19-bisepoxycembra-6,8(19),11,15-tetraene] (2), have been isolated from the Dufour gland secretion of the Brazilian ant Crematogaster brevispinosa rochai. Their structures, including the relative configuration, have been determined by a com
The structures of two fungal norsesquiterpenes containing a diepoxide functionality, isolated from cultures of the basidiomycete Resupinatus leightonii, were elucidated by a combination of X-ray analysis, NMR spectroscopy and molecular mechanics calculations.
In this study, the authors develop knowledge and insights on how the perception of interestingness influences the structure and focus of conversations in entrepreneurial education (EE) research. In particular, the authors elaborate on what is perceived as interesting among different subgroups of EE researchers, and not least, how EE researchers can identify and engage in scholarly conversation wit
Corporate decision-makers form their intention to adopt new technology for their venture based on their perception of its usefulness and ease of use. However, the formation of this intention might be influenced by the fear of missing out (FOMO), making decision-makers fear losing their relatedness with fellow managers and leading to decisions based on irrational considerations. We draw on and exte
Although there are many technological solutions and policy approaches for transitioning to a fossil-free society, effective action is still lacking. We need a new way to address the issue, one that inspires and attracts the widest possible group of society. Against this background, the aim of this paper is to explore citizens' political agency in influencing transport policy, and the inner and out
The population is getting increasingly older, and old age is correlated with decreased functional capacity. In society, continuous improvements in accessibility of public environments is apparent. Together, these two factors contribute to the trend that the people that are expected to perform self-evacuation today are more diverse in abilities than ever. Functional capacity refers to the abilities
Purpose: Gender dysphoria is commonly conceptualized as a mental disorder in gender-diverse people who do not identify with the gender assigned to them at birth. Direct support for well-being tends to be delegated to the field of mental health (MH), whereas speech-language pathology (SLP) practice is charged with modifying gender-diverse people's voice and communication in the belief that well-bei
Vi spenderar en tredjedel av våra liv sovandes och sömn är en avgörande faktor för god hälsa och välbefinnande. Men det är även viktigt att erkänna sömnens komplexitet, eftersom det är flera faktorer som kan påverka sömnen. Både biologiska, kontextuella och psykosociala faktorer har inverkan på ungdomarnas sömn. Otillräcklig sömn, sömnproblem och symptom på insomni är vanligt hos ungdomar. SömnlösInsufficient sleep, sleep problems and insomnia are common in adolescents, and insomnia and insufficient sleep are public health concerns that can impact adolescents’ mental and physical health. There are several different treatments for sleep problems and insomnia, and there is a great focus on the problem when it has already arisen. However, since this is a public health problem, it is important
Accurate precipitation data are crucial for hydrological modelling and rainwater runoff management. Precipitation variability exists through a wide range of spatial and temporal scales and cannot be captured well using sparse rain gauge networks. This limitation is further emphasised for urban and mountainous catchments, especially under global warming, causing an increased frequency of extreme ev
The purpose of this study is to look into patronage effects of extended supply outside peak hours on regional public transport services. Previous studies have shown that the service frequency is an attribute of great importance for regional passengers, but little is known about the details regarding peak and off-peak frequencies or service hours. The present study addresses this knowledge gap, dep
The market for ready-to eat vegetables is increasing, but unfortunately so do the numbers of food-borne illness outbreaks related to these products. A previous study has identified bacterial strains suitable for biocontrol of leafy green vegetables to reduce the exposure to pathogens in these products. As a tentative safety evaluation, five selected strains (Rhodococcus cerastii MR5x, Bacillus coa
