The challenging synthesis of a fused C3-symmetric trilactam (1) was executed in racemic and enantiomerically pure form. The rigidity, symmetry and high density of hydrogen bonding motifs make 1 an attractive candidate for self-assembly study, which revealed different hydrogen bond patterns in the crystals of rac-1-d3 and (+)-(SSS)-1.

Biodiversity is in decline due to human-induced pressures on ecosystems around the world. To be able to counteract this alarming trend, it is paramount to closely monitor biodiversity at global scales. Because this is practically impossible with traditional methods, the last decade has seen a strong push for new solutions. In aquatic ecosystems, the monitoring of species from environmental DNA (eD

Construction of subway line intersection stations will become more and more popular in the future. Research on the deformation characteristics in the construction process is the best way to ensure the safety of the foundation pit itself, the surrounding buildings, and adjacent subway stations. In this paper, the deformation characteristics of a T-shaped subway foundation pit during construction ar

cBN-based materials are well known for their high chemical inertness and high performance. The variation of binder phase type and amount enable improvement of performance even more. Comprehensive investigation of the influence of type of niobium compound (NbC and NbN) as a binder phase for cBN-based materials were done. Samples were prepared by high pressure high temperature (HPHT) sintering under

Tillit till människors omdöme är grundläggande i demokratin och avgörande för att organisationer och samhällen ska bli framgångsrika. Särskilt viktig är tilliten till de medborgare och professioner som möts i kärnuppdraget. Genom att utgå från behoven i medborgarmötet, i stället för att detaljstyra på långt avstånd, kan den offentliga sektorn förbättra kvalitet, effektivitet och arbetsmiljö. Detta

Pretreatment by reversible electroporation followed by resting (storage under saturated moisture at 21 ± 2 °C) was evaluated for modification of the properties of dried and rehydrated Thai basil leaves. The treated leaves were dried by convection at 40 °C or in a vacuum at room temperature. The results showed that vacuum drying provoked more cell damage and tissue collapse than convective air dryi

Magnesium metal and its alloys are lightweight and environment-friendly with tunable complex of structural and functional properties. However, significant gaps in understanding and assessing the degradation of these materials still remain, largely due to the limitations of existing experimental methods. Our novel laboratory-scale instrument combining isothermal calorimetry with pressure measuremen

Priority effects occur when the order of species arrival affects subsequent ecological processes. The order that pollinator species visit flowers may affect pollination through a priority effect, whereby the first visitor reduces or modifies the contribution of subsequent visits. We observed floral visitation to blueberry flowers from honeybees, stingless bees or a mixture of both species and inve

Injectable bioelectronics could become an alternative or a complement to traditional drug treatments. To this end, a new self-doped p-type conducting PEDOT-S copolymer (A5) was synthesized. This copolymer formed highly water-dispersed nanoparticles and aggregated into a mixed ion-electron conducting hydrogel when injected into a tissue model. First, we synthetically repeated most of the published

Due to their wide utilization and low thermodynamic efficiency, there is a large interest in designing more efficient high-pressure homogenizer valves. Drop breakup in these devices is by turbulent interaction downstream of the gap exit. However, recent investigations in scaled systems suggest that the drops can be ‘primed’ for breakup by elongation upstream of the gap entrance. This study uses hy

Sedan 70-talet har antalet separationer i Sverige ökat med många ombildade familjer till följd. Människor i alla åldrar möter nya partners vilket ofta innebär att också den nya partnerns familjerelationer blir del av ens liv och skapar komplexa familjerelationer i flera led. Nästan hälften av alla frånskilda svenskar är idag i åldrarna 60+ och många av dem lever i, eller har någon gång levt i, omb

BackgroundThere has been an increased focus on clinical practice that may reduce severe perineal trauma due to awareness of the associated morbidity. Knowledge regarding the best practice to reduce these injuries is limited. Collegial midwifery assistance during the second stage of labour that involves an additional midwife being present has recently been implemented into many Swedish birth units
