Yellow Fever

Yellow Fever is a disease that is most common in Africa and South America that causes severe discomfort and has a high mortality rate, of the estimated over 200,000 cases of Yellow Fever, 30,000 cases end in death. Since it is so dangerous, it is important to know how to prevent and treat it if someone ever wanted to travel to either of those places. The disease is relatively easy to avoid, all someone really need to do is avoid mosquitoes either by wearing protective clothing or by avoiding high density mosquito areas. If one were get Yellow Fever, they would surely regret it, since the side effects include head and muscle aches, fever, vomiting blood, yellow skin and eyes, seizures and the possibilities of a coma or even death (University of Maryland Medical Center, 2015)

Children as Bushfire Educators - 'Just be Calm, and Stuff Like That'

The limited evidence about disaster education programs for children indicates that they can increase disaster resilience, family based preparedness activities and reduce child fear and anxiety. However there are still gaps in the literature, including qualitative studies to provide insights into children’s experiences of disaster education programs, and follow up with children who are impacted by actual disasters. This paper reports on a pilot study in Victoria, Australia of a ‘Survive and Thrive’ bushfire education program delivered by the local Fire Brigade and incorporated into the school curricula for upper primary school children in Anglesea, a coastal town with very high bushfire risk. A mix of longitudinal qualitative methods captures the child experience and the program impacts including impact on child agency. The results show the children enjoyed the program and valued the life skills acquired. They demonstrated knowledge and skills gained in monitoring environmental risks and bushfire behaviour, and more nuanced understanding of the differential roles of adults and children in responding to a bushfire in different contexts. Faced with the reality of a nearby bushfire in the summer holidays, children demonstrated their capacity to apply their knowledge and to contribute to family response.

Comparison of Joint Moments and Joint Contributions to Total Support Moment during the Propulsive Phase of a Triple Hop Task between Healthy and ACL Reconstructed Females

Recent research suggests that individuals might use compensatory movement patterns in their ACL-reconstructed (ACLR) limb when performing a triple hop (TH) to overcome quadriceps weakness. The purpose of this study was to determine if ACLR females exhibit differences in TH performance compared to previously uninjured females. Nineteen females with ACLR and 19 without completed three THs during which hop distance was recorded and lower extremity biomechanics assessed. Hip, knee, and ankle joint extensor moment impulses, total support moment impulse (TSM), and joint contributions to TSM during the propulsive phase of the first hop were calculated and the influences of previous ACL injury, joint, and their interaction on the outcome variables was assessed. Previous history of ACLR did not influence hop performance, TSM, or individual joint impulse magnitudes or contributions to TSM. However, irrespective of group, the ankle, rather than the knee, produced the greatest joint moment impulse and was the largest contributor to TSM. This suggests that the previously reported lack of association between quadriceps function and single leg TH performance is not the result of compensatory strategies following ACLR, but most likely results from the ankle and not the knee being the primary contributor to propulsion

Accountable authentication with privacy protection: The Larch system for universal login

Credential compromise is hard to detect and hard to mitigate. To address this problem, we present larch, an accountable authentication framework with strong security and privacy properties. Larch protects user privacy while ensuring that the larch log server correctly records every authentication. Specifically, an attacker who compromises a user's device cannot authenticate without creating evidence in the log, and the log cannot learn which web service (relying party) the user is authenticating to. To enable fast adoption, larch is backwards-compatible with relying parties that support FIDO2, TOTP, and password-based login. Furthermore, larch does not degrade the security and privacy a user already expects: the log server cannot authenticate on behalf of a user, and larch does not allow relying parties to link a user across accounts. We implement larch for FIDO2, TOTP, and password-based login. Given a client with four cores and a log server with eight cores, an authentication with larch takes 150ms for FIDO2, 91ms for TOTP, and 74ms for passwords (excluding preprocessing, which takes 1.23s for TOTP).Comment: This is an extended version of a paper appearing at OSDI 202

Carbonate : an alternative dopant to stabilize new perovskite phases ; synthesis and structure of Ba3Yb2O5CO3 and related isostructural phases Ba3Ln2O5CO3 (Ln = Y, Dy, Ho, Er, Tm and Lu)

In this paper we report the synthesis of the new layered perovskite oxide carbonate, Ba3Yb2O5CO3. This phase is formed when 3BaCO(3):1Yb(2)O(3) mixtures are heated in air at temperatures 1000 degrees C, while above this temperature the carbonate is lost and the simple oxide phase Ba3Yb4O9 is observed. The structure of Ba3Yb2O5CO3 was determined from neutron diffraction studies and consists of a tripled perovskite with double Yb-O layers separated by carbonate layers, the first example of a material with such a structure. Further studies showed that analogous Ba(3)Ln(2)O(5)CO(3) phases could be formed for other rare earths (Ln = Y, Dy, Ho, Er, Tm and Lu). The results highlight the ability of the perovskite structure to accommodate carbonate groups, and emphasise the need to consider their potential presence particularly for perovskite systems prepared in lower temperature synthesis routes
