The continuation of historical value is enduring: Spirit of culture value is the regenerative power of heritage architecture
In this thesis, it describes that spirit is the regenerative power in heritage design, and explained how it was inherited from past and still remain alive nowadays. A certain kind of method will be approached to help with the research on this topic. Since heritage design is the re-design based on the existing building, historical research places an important role during the architectural research. It shows the memory of the site. However, besides historical value and age value, other values such as use value, newness value and rarity value should also be considered in the value assessment, which makes decisions between demolishing, reserving or redesigning more convincing. Furthermore, the value assessment encourages architects reflect on history and find strategies for new design fit for the nowadays and look to the future. The value assessment can help find out the spirit of the heritage and the spirits of the can help to bring building into new life.Acciona, 2018 SUSTAINABLE BUILDING MATERIALS, Retrieved Spetember 17, 2019 from https://www.activesustainability.com/construction-and-urban-development/sustainable-building-materials/https://www.activesustainability.com/construction-and-urban-development/sustainable-building-materials/ Fermacell, 2019 Special solutions Underfloor heating, Retrieved October 15, 2019 fromhttps://www.fermacell.nl/nl/vloersystemen HNS Aluminium, . 2018, The weight of double and triple glass unit, Retrieved Nov. 23, 2019 from https://www.hnsaluminium.co.uk/the-weight-of-double-and-triple-glass-units/ ,Petzet, M.

Lipopolysaccharides promote pulmonary fibrosis in silicosis through the aggravation of apoptosis and inflammation in alveolar macrophages
Alveolar macrophages (AMs) play an important defensive role by removing dust and bacteria from alveoli. Apoptosis of AMs is associated with lung fibrosis; however, the relationship between this apoptotic event and environmental factors, such as the presence of lipopolysaccharides (LPSs) in the workplace, has not yet been addressed. To investigate whether exposure to LPS can exacerbate fibrosis, we collected AMs from 12 male workers exposed to silica and incubated them in the presence and absence of LPS for 24 h. We show that the levels of cleaved caspase-3 and pro-inflammatory cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha were increased in these AMs following LPS treatment. Moreover, we demonstrate that LPS exposure aggravated apoptosis and the release of inflammatory factors in AMs in a mouse model of silicosis, which eventually promoted pulmonary fibrosis. These results suggest that exposure to LPS may accelerate the progression of pulmonary fibrosis in silicosis by increasing apoptosis and inflammation in AMs
Examining a Sequential Mediation Model of Chinese University Students’ Well-Being: A Career Construction Perspective
Despite career construction theory attends to individual subjective career and provides a useful lens to study well-being, extant research has yielded limited insights into the mechanisms through which career construction variables influence individual well-being. To address this important gap, the present study examined a mediation model that links indicators of career adaptivity (big-five personality and approach/avoidance traits) to psychological well-being (psychological flourishing and life satisfaction) through career adaptability and in sequent meaning of life (presence of life meaning and search for life meaning) among a sample of Chinese university students (N = 165). The results of a two-wave survey study showed that career adaptability and presence of life meaning mediated the effects of openness to experience, consciousness, approach trait, and avoidance trait on individual well-being in sequence. The results also showed that approach trait’s effect on presence of meaning was partially mediated by career adaptability; career adaptability’s effect on psychological flourishing was partially mediated by presence of meaning. These findings advance understanding of antecedents to individual well-being from a career construction perspective, and carry implications for career education and counseling practices
Investigation of the toxicity of the ionic liquid 1-butyl-3-methylimidazolium chloride to Saccharomyces cerevisiae AY93161 for lignocellulosic ethanol production
Ionic liquid (IL) pretreatment of lignocellulosic materials has provided a new technical tool to improve lignocellulosic ethanol production. To evaluate the influence of the residual IL in the fermentable sugars from enzymatic hydrolysis of IL pretreatment of lignocellulosic materials on the subsequent ethanol fermentation, the toxicity of the IL 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) to Saccharomyces cerevisiae AY93161 was investigated. Firstly, the morphological structure, budding and metabolic activity of Saccharomyces cerevisiae AY93161 at different [BMIM]Cl concentrations were observed under an optical microscope. The results show that its single cell morphology remained unchanged at all [BMIM]Cl concentrations, but its reproduction rate by budding and its metabolic activity decreased with the [BMIM]Cl concentration increasing. The half effective concentration (EC50) and the half inhibition concentration (IC50) of [BMIM]Cl to Saccharomyces cerevisiae AY93161 were then measured using solid and liquid suspension culture and their value were 0.53 and 0.39 g.L-1 respectively. Finally, the influence of [BMIM]Cl on ethanol production was investigated. The results indicate that the [BMIM]Cl inhibited the growth and ethanol production of Saccharomyces cerevisiae AY93161. This toxicity study provides useful basic data for further development in lignocellulosic ethanol production by using IL technology and it also enriches the IL toxicity data
A Centimeter-Scale Dielectric Metasurface for the Generation of Cold Atoms
The
single-beam magneto-optical trap (MOT) based on the diffractive
optical element offers a new route to develop compact cold atom sources.
However, the optical efficiency in the previous single-beam MOT systems
is usually low and unbalanced, which will affect the quality of the
trapped atoms. To solve this issue, we developed a centimeter-scale
dielectric metasurface optical chip with dynamic phase distributions,
which was used to split a single incident laser beam into five separate
ones with well-defined polarization states and uniform energy distributions.
The measured diffraction efficiency of the metasurface is up to 47%.
A single-beam MOT integrated with the metasurface optical chip was
then used to trap the 87Rb atoms with numbers ∼1.4
× 108 and temperatures ∼7.0 μK. The proposed
concept in this work may provide a promising solution for developing
ultracompact cold atom sources
