Abstract Designing laboratory activities is a real challenge for those working in higher education. There often an acknowledged frustration with the status quo, but lack of clear guidance on what strategies might be useful considering redesign. This article aims to address question: considerations should taken into account when designing activity? To it, we first describe overarching framework learning, describing it as complex learning environment. The reason this that two guidelines emerge...

Rice husk-based activated carbon was prepared with the help of zinc chloride using microwave and electrical dual-mode heating. The pore characteristics chemical properties rice (RH-AC) were characterized by BET, XRD, Raman spectra, FTIR pHIEP (pH isoelectric point). specific surface area RH-AC is 1719.32 m2/g a total volume 1.05 cm3/g. performance for removing Cr(VI) from aqueous solution examined considering variation contact time (0–120 min), pH value (2.0–9.0), adsorbent dose (0.5–3.0...

Matching material degradation with host remodeling, including endothelialization and muscular is important to vascular regeneration. We fabricated 3D PGS-PCL grafts, which presented tunable polymer components, porosity, mechanical strength, degrading rate. Furthermore, highly porous structures enabled patterning of conjugated heparin-binding peptide, dimeric thymosin β4 (DTβ4), played key roles in antiplatelets, fibrinogenesis inhibition, recruiting circulating progenitor cells, thereafter...

Abstract Developing a self‐expanding hemostatic sponge with high blood absorption and rapid shape recovery for noncompressible hemorrhage remains challenge. In this study, 3D‐printed cuttlefish bone elastomeric (CBES) is fabricated, which combined ordered channels porous structures, presented tunable mechanical strength, memory potentials. The incorporation of powder (CBp) plays key roles in concentrating components, promoting aggregation red cells platelets, activating makes CBES show...

Stem cells derived extracellular vesicles (EVs) conceive cues essential for tissue repair. Mammalian cartilaginous matrix (cECM) may not be optimally inductive tracheal regeneration because of the granulomatous, instead regenerative, responses in injured adult mammalian tracheas. Given high regenerative capacity gingiva, it is hypothesized human gingival mesenchymal stem EVs (gEVs) can induce epithelia regeneration. Coculturing chondrocytes with GMSCs produce abundant "matrix bound gEVs...

In bipolar SiC devices, which are promising under ultra-high voltage operation, the carrier lifetime is a highly influential parameter for device performance. Surface recombination one of limiting factors lifetime, and quantitative values surface velocities required design development fabrication processes devices. this study, we observe at various temperatures Si- C-faces n- p-type 4H-SiC samples a- m-faces n-type with treatment chemical mechanical polishing or reactive ion etching by using...

NCN pincer six-membered NHC palladium complexes were synthesized, characterized and used in Heck reaction of aryl bromides with olefines.

Abstract Regenerating nonthrombotic and compliant artery, especially in the aging body, remains a major surgical challenge, mainly owing to inadequate knowledge of cell sources contributing arterial regeneration insufficient bioactivity delivered peptides grafts. Ultrathin nanofibrous sheaths stented with biodegrading elastomer present opening channels reduced material residue, enabling fast recruitment host remodeling, while incorporating offering developmental cues are challenging. In this...

The advent of modern light-emitting diode (LED) techniques enables us to develop novel lighting systems with numerous previously unavailable features. Specifically, by using the fixtures for both illumination and interrogate space, source-to-sensor communication becomes possible at very low cost. In this paper, we present a framework estimate occupancy distribution in an indoor space color-controllable LED (the same providing illumination, simultaneously) sparsely distributed non-imaging...

Liver cancer is a major healthcare problem and one of the leading causes cancer-associated mortality in world. To date, chemotherapy remains common method for treating cisplatin most widely used chemotherapeutics. However, owing to drug resistance side effects, it imperative identify novel approach improve anticancer effect cisplatin. Auxiliary drugs with minor toxicity normal cells may represent strategy therapy. Previous studies have indicated that ginkgol C17:1 exhibits effects liver...

In this paper, we present a framework to roughly reconstruct the 3D occupancy scenario of an indoor space using color-controllable light and distributed color sensors. By applying randomly generated perturbation patterns onto input LED fixtures, measuring changes sensor readings, are able recover transport model (LTM) room. Then variant inverse Radon transform is applied on LTM scene. The reconstructed scene by our algorithm can faithfully reveal space, while preserving privacy human...

Clinically, arterial injuries are always accompanied with perivascular tissue damage, which may contribute to high failure rate of vein grafts due intimal hyperplasia and acute thrombosis. In this study, a "perivascular (PVT) deprivation" animal model is constructed mimic clinical scenarios identify the contribution PVT success grafts. Proteomics analysis suggests that depriving exacerbate reactive oxygen species (ROS)-induced endothelial apoptosis by up-regulating inflammation response...

In traditional vision systems, high level information is usually inferred from images or videos captured by cameras, depth sensors. These images, whether gray-level, RGB, depth, have a human-readable 2D structure which describes the spatial distribution of scene. this paper, we explore possibility to use distributed color sensors infer information, such as room occupancy. Unlike camera, output sensor has only few variables. However, if light in controllable, can outputs multiple under...

Psychological stress is closely related to the mental and physical health of soldiers. We explored relationships between stress, optimistic intelligence, emotion regulation in Chinese Navy personnel ( N = 452), who completed General Information Questionnaire, Stress Self-Evaluation Test, Adult Optimistic Intelligence Quotient Emotion Regulation Questionnaire this cross-sectional study. Results show that was negatively correlated with perceived happiness ability respond positively negative...

Abstract Currently, the successful healing of critical-sized calvarial bone defects remains a considerable challenge. The immune response plays key role in regulating regeneration after material grafting. Previous studies mainly focused on relationship between macrophages and marrow mesenchymal stem cells (BMSCs), while dural were recently found to play vital healing. In this study, series 3D elastomers with different proportions polycaprolactone (PCL) poly(glycerol sebacate) (PGS)...

William Somerset Maugham is a famous British novelist and playwright, known for his expertise in portraying characters depicting the complexity of human nature. The novel Painted Veil, one Maugham's representative works, focuses on experience heroine Kitty her changes state mind. It explores process female spiritual awakening from ignorance to independence, with distinct feminist features. At time novel's creation, Western women's liberation movement was full swing. wave liberating women...
