“…Administration of OBS-E at a concentration of 50 or 200 mg/kg BW once a day for 14 weeks was well-tolerated and no abnormal signs or significant changes in body weight changes were observed, thus indicating that the administration schedule and doses were safe. These results are consistent with those of a previous report which reported that O. biennis administration is not associated with any toxicity issues [ 20 ]. Significant differences were observed in all parameters measured for the UVB-irradiated control group compared with those for the non-irradiated control group, demonstrating that our UVB irradiation process induced damage in the mice.…”

Most of the studies on common evening primrose (Oenothera biennis L.) are focused on its oils (isolated from seed, root, and stem tissues). We aimed to investigate the effect of the oral administration of OBS-E on the improvement of skin function in skin-damaged hairless mice exposed to excessive ultraviolet B (UVB) radiation owing to the preliminary in vitro findings regarding the antioxidant, anti-wrinkle, and skin moisturizing activities of OBS-E. OBS-E administration for 14 weeks did not significantly affect the body weight or clinical signs. Significant reductions were observed in wrinkle parameters (area, number, length, and depth, and metalloproteinase levels) in OBS-E-administered mice compared with those in UVB-irradiated control mice. OBS-E significantly increased skin elasticity and hyaluronic acid content, but it significantly decreased transepidermal water loss. Histomorphometrical analysis revealed that OBS-E significantly reduced the epidermal thickness, area of the collagen-occupied region, and number of microfolds and inflammatory and mast cells. These results demonstrate that OBS-E can effectively enhance skin functions in terms of ameliorating wrinkle formation, promoting skin-moisturization, enhancing skin barrier function, and inhibiting inflammatory reactions. The obtained results provide good starting point for the continuation in the process of developing new inner beauty products based on OBS-E.

“…Additionally, our study only captured bumble bee choice for plant species visited during the period of 10:00-16:00, eliminating observations of visits to species that specialize in attracting pollinators outside these hours. For example, Mimulus ringens (Christopher et al, 2021) and Tradescantia ohiensis (Parrish & Bazzaz, 1979) receive most visits before 10:00, while Oenothera opens late in the day (Steckel et al, 2019). Therefore, a strong knowledge of the natural history of individual plant species should inform planting decisions.…”

Regionally specific flower preference data are needed to optimize conservation habitat plantings for at-risk pollinators such as bumble bees (Bombus spp.).Current tools for selecting flowers for plantings rely on raw bee flower visits, which can be biased toward abundant flowers. To assist in planning habitat enhancements for bumble bees, we quantified genus-and species-level floral preferences using a selection index that accounts for floral availability. Through 477 h of observation in Ohio, USA during the summers of 2017 and 2018, we recorded 22,999 observations of eight Bombus species visiting 96 flowering plant taxa. As a genus, Bombus selected flowers nonrandomly; the most strongly preferred plants included Asclepias spp., Cirsium spp., Convolvulaceae, Dipsacus spp., Echinacea purpurea, Monarda fistulosa, Penstemon digitalis, and Silphium spp. Only a few Fabaceae were highly selected (Baptisia spp., Trifolium pratense, and Vicia spp.), while some were preferred only during their peak bloom (Securigera varia), and others were not preferred by bumble bees (T. hybridum and Melilotus spp.). Diets differed among habitats, and in restored meadows, bumble bees selected for native planted species such as Monarda fistulosa, Asclepias syriaca, Echinacea purpurea, Penstemon digitalis, and Silphium spp. Diets and preferences shifted over the season, largely driven by changes in plant phenologies (e.g., in June, Penstemon was strongly selected, in July, Asclepias, and in August, Verbena). For the three most common Bombus (B. impatiens, B. griseocollis, and B. bimaculatus), rarefaction analysis indicates that we were able to detect almost all plants in their summer diets. However, for five less common species, even our extensive sampling was insufficient to fully characterize their diets. The common Bombus species differed in their feeding niches, perhaps reducing interspecific competition. In contrast, we found high diet overlap between three rarer species-B. vagans, B. fervidus, and B. pensylvanicus, suggesting that these at-risk species might benefit from different floral communities than would the common species.

“…An example is now given to illustrate the object selection process. First, an Oenothera biennis, also known as the common evening-primrose (Steckel et al 2019), represents dusk and therefore the time when the lights should be turned on. Conversely, the user decides to use a sunflower (Kutschera and Briggs 2016) to represent dawn and thus the time when the lights should be turned off.…”

The English language is but one of many languages globally in use, yet it seems to dominate the world of automation in its application to computer programming. Our research considers a programming environment in which the written word is not relevant; instead of text, we consider the use of physical objects to represent simple computer programs. This paper presents a reality in which artefacts, based on culturally significant objects, are chosen and arranged by the layperson in order to control the behaviour of light bulbs in a domestic environment. This work incorporates aspects of Gestalt theory and visual perception theory. We give an overview of prior work and conclude with an example.
