We investigated cpDNA sequence and nuclear microsatellite variation among populations of the wild daffodil Narcissus triandrus to examine the role of historical vs. contemporary forces in shaping population structure, morphological differentiation and sexual-system evolution. This wide-ranging heterostylous species of the Iberian Peninsula is largely composed of two allopatric varieties (vars. ...

A gene encoding a RING zinc finger ankyrin repeat protein (MjXB3), a putative E3 ubiquitin ligase, is highly expressed in petals of senescing four o'clock (Mirabilis jalapa) flowers, increasing >40,000-fold during the onset of visible senescence. The gene has homologues in many other species, and the Petunia homologue is strongly up-regulated in senescing Petunia corollas. Silencing the express...

Morphological instabilities play a key role in the evolution of form and function growing biomaterials. Spatially varying differential growth, particular, leads to residual stresses that for soft materials or slender geometries are favourably relieved by out-of-plane buckling wrinkling. While onset instability biomaterials has been studied extensively, post-critical regime remains poorly unders...

Innovations are an essential factor of competition for manufacturing companies in technical industries. Patent information plays an important role within innovation-processes and for human innovators working on innovations. Innovation-processes support the combination of cross-organisational spread information and resources from patent databases and digital libraries is necessary in order to ga...

‘Golden Rice’ is a variety of rice engineered to produce bcarotene (pro-vitamin A) to help combat vitamin A deficiency1, and it has been predicted that its contribution to alleviating vitamin A deficiency would be substantially improved through even higher b-carotene content2. We hypothesized that the daffodil gene encoding phytoene synthase (psy), one of the two genes used to develop Golden Ri...

The interaction of a series of synthetic, branched trisaccharides with five D-mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl alpha-D-mannotrioside, alpha-D-Manp-(1----3)-[alpha-D-Manp-(1----6)]-alpha-D-Man pOMe, the best inhibitor of the Con A-Dextran interaction, was 42 times more potent than alpha-D-ManpOMe, and 3-6 times more potent than the two t...

Objective. We examined the bibliometric characteristics of 3616 Bangladesh’s publications on Covid-19 during 2020-2023. For this purpose, we used quantitative and qualitative indicators.
 Design/Methodology/Approach. Bangladesh 2020-2023 were retrieved using Scopus database. From each record, data title, author, organizations, journal, publication type source, country, collaboration, fundi...

Two experimental studies were undertaken to investigate the processes of reincorporation and redistribution of trace evidence on garments when worn by a suspect or a victim (reincorporation) or after the garments have been seized and packaged for subsequent forensic analysis (redistribution). The first experiment utilised UV powder, an established proxy for geoforensic trace particulates and th...
