Biomolecule derivatives are transversally used in nanotechnology. Deciphering their aggregation behavior is a crucial issue for the rational design of functional materials. To this end, it is necessary to build libraries of selectively functionalized analogues and infer general rules. In this work we enrich the highly applicative oriented collection of steroid derivatives, by reporting a rare exam
The requirements on increasing functionality, quality, and, customisation, while reducing cost has lead to the introduction of an architecture centred development process for electronic systems at Volvo Cars. This process enables better control of system integration and achieving non-functional requirements, such as reusability, understandability, etc. The result of the process is a reference arch
Lipase from Candida rugosa immobilized on Celite was employed as the biocatalyst in order to examine the effect of the reaction medium upon enzymic activity and selectivity. As the model reaction, transesterification between tributyrin and pentan‐2‐ol in iso‐octane (2,2,4‐trimethylpentane) was chosen. A small amount of water (0.05%, v/v) was added to the reaction medium. Enhanced transesterificati
Emerging nonlinear optical spectroscopies enable deeper insight into the intricate world of interactions and dynamics of complex molecular systems. 2D electronic spectroscopy appears to be especially well suited for studying multichromophoric complexes such as light-harvesting complexes of photosynthetic organisms as it allows direct observation of couplings between the pigments and charts dynamic
Three different SPE sorbents (weak cation exchange, mixed cation exchange, and hydrophobic-lipophilic balance polymers) were compared in terms of recovery, precision, and the effect of matrix components on analyte response for the determination of fluoroquinolones antibiotics. The influence of ethylenediaminetetraacetic acid disodium salt (Na(2)-EDTA) was as well tested. Two of the sorbents, hydro
OBJECTIVE: To describe the sonographic characteristic of squamous cell cancer (SCC) and adenocarcinoma (AC) of the cervix using transvaginal ultrasound. METHODS: Women with early stage cervical cancer undergoing transvaginal ultrasound examination prior to surgery were prospectively included. The sonographic characteristics were assessed with regard to tumor morphology, vascularization, size, exte
GABA is the major inhibitory neurotransmitter in the CNS and changes in GABAergic neurotransmission affect the overall activity of neuronal networks. The uptake of GABA into synaptic vesicles is mediated by the vesicular GABA transporter (VGAT), and changes in the expression of the transporter directly regulate neurotransmitter release. In this work we investigated the changes in VGAT protein leve
The hot erosion of turbine tip and the maintenance of tip reliability and service times have always been great challenges for researchers. This work presents a novel design of a tip wall with the internal surface fitted with delta-winglet vortex generator pairs (DVGP). Various spacing of DVGP is considered to study the influence of spacing on the internal tip heat transfer and flow behavior in the
Single motherhood has long been a feature of European family systems, but its meaning and determinants have changed substantially over time. Using longitudinal individual-level data from the Scanian Economic and Demographic Database (SEDD), covering southern Sweden between 1905 and 2015, we examine the changing demography of single motherhood from a long-term life course perspective. We analyze ho
Abstract – There is a growing interest in the genomic and developmental basis of discrete or multimodal phenotypes governed by genetic polymorphisms. Recent research has uncovered the genomic basis of such polymorphisms and their maintenance through balancing selection such as negative frequency-dependent selection (NFDS). Such polymorphisms often originate through structural genomic changes or th
1,2-butadiene (1,2-C4H6) is one of four C4H6 isomers that could appear during pyrolysis and oxidation of heavier hydrocarbons and/or contribute to the formation of aromatic species in flames. However, it is seldom included in detailed kinetic mechanisms due to a lack of studies of its combustion characteristics. In this work, laminar burning velocities (LBV) of 1,2-butadiene flames have been measu
Background: Small bowel neuroendocrine tumours often present with locally advanced or metastatic disease. The aim of this paper is to provide evidence-based recommendations regarding (controversial) topics in the surgical management of advanced small bowel neuroendocrine tumours. Methods: A working group of experts was formed by the European Society of Endocrine Surgeons. The group addressed 11 cl
We present the results of the commissioning of a 28-pole 2 T Hybrid Wiggler at the electron storage ring of the Brazilian Synchrotron Light National Laboratory (LNLS). The wiggler will be used mainly for protein crystallography and was optimized for the production of 12 keV photons. We describe the effects of the insertion device on the storage ring lattice, such as the correction of the linear tu
The first ICDRG (International Contact Dermatitis Research Group) classification of patch test reactions was published in 1970. With this classification, many weak reactions were classified as allergic reactions. A second classification was therefore implemented one decade later on behalf of the ICDRG and the North American Contact Dermatitis Group. This classification was adopted by the European
Background: Happiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings and emotions) and judgements of a self-imposed ideal (i.e., the cognitive dimension: life satisfaction). Recent research has established these two dimensions as primary parts of a higher order factor. Ho
This chapter explores the relevance of the Christian tradition to contemporary debates on solidarity in international law and human rights. It positions the genealogy of solidarity within early Christian writings in which the western theological concepts of suffering, love, and salvation are detailed. Linking the Pauline doctrine and writings of early theologians to the processes of modernity – of
