Engineered bamboo has recently received lots of attention of civil engineers and professional researchers due to its better mechanical performance than that of softwood timber. Parallel strand bamboo is one important part of engineered bamboo for its excellent durable performance compared to the laminated veneer bamboo. The required curing temperature in hot-pressing process is usually higher than
Theorizing embeddedness requires sensitivity to the dynamic and multi-layered contexts that entrepreneurship is situated within. Social or network embeddedness offers explanation for how both social and for-profit entrepreneurs can leverage resources within their local environment. Institutional embeddedness is concerned with how the environment for entrepreneurship is shaped by social structures,
On February 18, 2021 NASA's Perseverance rover landed in Jezero crater, located at the northwestern edge of the Isidis basin on Mars. The uppermost surface of the present-day crater floor is dominated by a distinct geologic assemblage previously referred to as the dark-toned floor. It consists of a smooth, dark-toned unit overlying and variably covering light-toned, roughly eroded deposits showing
increased amounts of starch and sugar have been added to the diet in the Western world during the last decades. undigested carbohydrates lead to bacterial fermentation and gas production with diffusion of water, causing abdominal bloating, pain and diarrhea. Therefore, dietary advice is the first line of treatment of irritable bowel syndrome (IBS), a disease characterized by abdominal pain and alt
Material scientists are in need of experimental techniques that facilitate a quantitative mechanical characterization of mesoscale materials and, therefore, their rational design. An example is that of thin organic films, as their performance often relates to their ability to withstand use without damage. The mechanical characterization of thin films has benefited from the emergence of the atomic
Fe-based composite coatings were fabricated on Q235 steel substrate by plasma cladding. B4C particles were injected at the center and edge of the melting pool as strengthening phase. Scanning electron microscopy and pin-on-disc tribometer were applied to study the microstructure and wear resistance of the coatings. The results showed that the central injected B4C particles dissolved during plasma
We investigated the water sorption properties of macroporous cryogels of gelatine (Gel) and dextran dialdehyde (DDA) prepared via cryogelation at 260 K and following the freeze drying processes. Water vapour sorption isotherms for aerogels were studied at 293 K by two inde-pendent methods: static-gravimetric and dynamic vapour sorption (DVS) over a water activity range of 0.11–1.0. Experimental da
During the early months of the COVID-19 pandemic, there was an unusually high submission rate of scholarly articles. Given that most academics were forced to work from home, the competing demands for familial duties may have penalized the scientific productivity of women. To test this hypothesis, we looked at submitted manuscripts and peer review activities for all Elsevier journals between Februa
Personal cooling garments (PCGs) can represent an adaptation solution to counteract heat strain and to improve worker's health and productivity (especially for some outdoor work activities as in agriculture and in the construction industry). The cooling effect of a ventilation jacket was preliminarily investigated carrying out “dry” tests in a climatic chamber on a thermal manikin. A standardized
The reliable detection of neutrons in a harsh gamma-ray environment is an important aspect of establishing non-destructive methods for the characterization of spent nuclear fuel. In this study, we present results from extended in-situ monitoring of detector systems consisting of commercially available components: EJ-426, a 6Li-enriched solid-state scintillator material sensitive to thermal neutron
SPRINT (Systolic Blood Pressure Intervention Trial) showed that intensive lowering of systolic blood pressure to <120 mm Hg was beneficial, as compared with standard treatment in which systolic blood pressure is lowered to <140 mm Hg. The proposal that the results of SPRINT were mainly driven by the reduction of heart failure events has undermined the main conclusion of the study. Therefore, this
Background: Patent false lumen has been shown to have a negative impact on prognosis after surgery for acute type A aortic dissection (ATAAD). We aimed to assess the effect of postoperative anticoagulation on false lumen patency and clinical outcomes in relation to false lumen status. Methods: Postoperative computed tomographies of 156 patients undergoing ATAAD DeBakey type I surgery were retrospe
Background and aim: Whether long-term oxygen therapy (LTOT) improves survival in interstitial lung disease (ILD) is unclear. A recent study reported similar survival in ILD patients with severe hypoxemia on LTOT vs. moderate hypoxemia without LTOT, and proposed that LTOT could be indicated in ILD already at moderate hypoxemia. The aim of this study was to compare survival by severity of hypoxemia
OBJECTIVE: To analyze changes in primary care utilization as a result of the Covid-19 pandemic. Swedish national register data from 2019 to 2020 on utilization of services were used to compare overall utilization levels and across types of contacts and patient groups. A specific objective was to assess the extent to which remote types of patient consultations were able to compensate for any observ
Background: According to the “brain-reserve hypothesis” in Alzheimer’s disease (AD), patients with more years of education are expected to have higher cognitive status during adulthood. Hence, they might have a relatively larger burden of AD pathology and a more advanced level of the disease when dementia is clinically evident. Higher educated people would also be expected to perform better on sta
The earless, nose-horned agamid lizard Pseudocophotis sumatrana is only represented by a few specimens in collections worldwide. We discovered a historical publication from 1855 by van der Hoeven where the species was described as Calotes nasicornis before the currently accepted original description by Hubrecht in 1879. In order to uphold nomenclatural stability, we provide proof that Calotes nasi
