TL;DR: In this paper, the difference between the near-IR spectra of palygorskites and sepiolites is attributed to the dioctahedral nature of the polygonal structure of the sepiolite and the Mg3(OH and Mg2(OH) units.

TL;DR: A strain-driven 90° lattice rotation is found in the magnetic VSSe monolayer with an extremely high reversal strain, indicating an intrinsic ferroelasticity and the combination of piezoelectricity and valley polarization make magnetic 2D Janus VSSe a tantalizing material for potential applications in nanoelectronics, optoelectronic, and valleytronics.
Abstract: Inspired by recent experiments on the successful fabrication of monolayer Janus transition-metal dichalcogenides [Lu, A.-Y.; Nat. Nanotechnol. 2017, 12, (8), 744 and ferromagnetic VSe2 [Bonilla, M.; Nat. Nanotechnol. 2018, 13, (4), 289], we predict a highly stable room-temperature ferromagnetic Janus monolayer (VSSe) by density functional theory methods and further confirmed the stability by a global minimum search with the particle-swarm optimization method. The VSSe monolayer exhibits a large valley polarization due to the broken space- and time-reversal symmetry. Moreover, its low symmetry C3v point group results in giant in-plane piezoelectric polarization. Most interestingly, a strain-driven 90° lattice rotation is found in the magnetic VSSe monolayer with an extremely high reversal strain (73%), indicating an intrinsic ferroelasticity. The combination of piezoelectricity and valley polarization make magnetic 2D Janus VSSe a tantalizing material for potential applications in nanoelectronics, optoelec...

Journal ArticleDOI
TL;DR: This article explored the relationship between, and psychological predictors of, frequency of mobile phone use and mobile phone involvement conceptualized as people's cognitive and behavioural interaction with their mobile phone. And they found that only self-identity and validation from others were explored as predictor of both types of behaviour.
Abstract: The present research was a preliminary examination of young Australians' mobile phone behaviour. The study explored the relationship between, and psychological predictors of, frequency of mobile phone use and mobile phone involvement conceptualised as people's cognitive and behavioural interaction with their mobile phone. Participants were 946 Australian youth aged between 15 and 24 years. A descriptive measurement tool, the Mobile Phone Involvement Questionnaire, was developed. Self-identity and validation from others were explored as predictors of both types of mobile phone behaviour. A distinction was found between frequency of mobile phone use and mobile phone involvement. Only self-identity predicted frequency of use whereas both self-identity and validation from others predicted mobile phone involvement. These findings reveal the importance of distinguishing between frequency of use and people's psychological relationship with their phone and that factors relating to one's self-concept and ...

TL;DR: There is no set prescription and total weekly dosage that would be considered evidence-based for all cancer patients, so targeted exercise prescription is needed to ensure greatest benefit in the short and longer term, with low risk of harm.

TL;DR: In this article, the effects of removing peripheral IV catheters when clinically indicated compared with removing and re-siting the catheter routinely were evaluated in seven trials with a total of 4895 patients.
Abstract: Background: US Centers for Disease Control guidelines recommend replacement of peripheral intravenous (IV) catheters no more frequently than every 72 to 96 hours. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection. Catheter insertion is an unpleasant experience for patients and replacement may be unnecessary if the catheter remains functional and there are no signs of inflammation. Costs associated with routine replacement may be considerable. This is an update of a review first published in 2010. Objectives: To assess the effects of removing peripheral IV catheters when clinically indicated compared with removing and re-siting the catheter routinely. Search methods: For this update the Cochrane Peripheral Vascular Diseases (PVD) Group Trials Search Co-ordinator searched the PVD Specialised Register (December 2012) and CENTRAL (2012, Issue 11). We also searched MEDLINE (last searched October 2012) and clinical trials registries. Selection criteria: Randomised controlled trials that compared routine removal of peripheral IV catheters with removal only when clinically indicated in hospitalised or community dwelling patients receiving continuous or intermittent infusions. Data collection and analysis: Two review authors independently assessed trial quality and extracted data. Main results: Seven trials with a total of 4895 patients were included in the review. Catheter-related bloodstream infection (CRBSI) was assessed in five trials (4806 patients). There was no significant between group difference in the CRBSI rate (clinically-indicated 1/2365; routine change 2/2441). The risk ratio (RR) was 0.61 but the confidence interval (CI) was wide, creating uncertainty around the estimate (95% CI 0.08 to 4.68; P = 0.64). No difference in phlebitis rates was found whether catheters were changed according to clinical indications or routinely (clinically-indicated 186/2365; 3-day change 166/2441; RR 1.14, 95% CI 0.93 to 1.39). This result was unaffected by whether infusion through the catheter was continuous or intermittent. We also analysed the data by number of device days and again no differences between groups were observed (RR 1.03, 95% CI 0.84 to 1.27; P = 0.75). One trial assessed all-cause bloodstream infection. There was no difference in this outcome between the two groups (clinically-indicated 4/1593 (0.02%); routine change 9/1690 (0.05%); P = 0.21). Cannulation costs were lower by approximately AUD 7.00 in the clinically-indicated group (mean difference (MD) -6.96, 95% CI -9.05 to -4.86; P 0.00001). Authors' conclusions: The review found no evidence to support changing catheters every 72 to 96 hours. Consequently, healthcare organisations may consider changing to a policy whereby catheters are changed only if clinically indicated. This would provide significant cost savings and would spare patients the unnecessary pain of routine re-sites in the absence of clinical indications. To minimise peripheral catheter-related complications, the insertion site should be inspected at each shift change and the catheter removed if signs of inflammation, infiltration, or blockage are present.
