Tuning glycerol plasticization of chitosan with boric acid.

Chitosan-based bioplastics are attractive biodegradable alternatives to petroleum-derived plastics. However, optimizing the properties of chitosan materials to fit a particular application or obtain a desired property is not a trivial feat. Here, we report the tunability of glycerol-plasticized chitosan films with the addition of boric acid.

Research to Translation: The Healthy Schools Toolkit and New Approaches to the Whole School, Whole Community, Whole Child Model.

Background: The Whole School, Whole Community, Whole Child (WSCC) model is an evidence-based comprehensive framework to address health in schools. WSCC model use improves health and educational outcomes, but implementation remains a challenge.

Methods: Working with 6 schools in 2 districts in the Midwest, we used a mixed-methods approach to determine the people, systems, and messages needed to activate WSCC implementation.

Email phishing and signal detection: How persuasion principles and personality influence response patterns and accuracy.

Phishing is a social engineering tactic where a malicious actor impersonates a trustworthy third party with the intention of tricking the user into divulging sensitive information. Previous social engineering research in a real-world setting has shown an interaction between the personality of the target and the persuasion principle used. This study investigated whether this interaction is present in the realm of email phishing.

Multiple Shape Coexistence in ^{110,112}Cd.

From detailed spectroscopy of ^{110}Cd and ^{112}Cd following the β^{+}/electron-capture decay of ^{110,112}In and the β^{-} decay of ^{112}Ag, very weak decay branches from nonyrast states are observed. The transition rates determined from the measured branching ratios and level lifetimes obtained with the Doppler-shift attenuation method following inelastic neutron scattering reveal collective enhancements that are suggestive of a series of rotational bands. In ^{110}Cd, a γ band built on the shape-coexisting intruder configuration is suggested.

Who's the real expert here? Pedigree's unique bias on trust between human and automated advisers.

Objective: We assessed the effects of source type bias (human or automation) on adviser trust in a dual adviser decision-making task.

Background: Source type and reliability's effects on adviser trust have been studied in a dual-adviser context, but the influence of pedigree (perceived expertise) across source types lacked robust investigation. As situations with two decision-aids of uneven pedigree can easily arise, it is critical to understand how operators are biased towards a decision-aid of a certain source type and pedigree.

High-precision half-life measurement for the superallowed β+ emitter ²⁶Al(m).

A high-precision half-life measurement for the superallowed β+ emitter 26Al(m) was performed at the TRIUMF-ISAC radioactive ion beam facility yielding T 1/2 6346.54 ± 0.46(stat) ± 0.

Internal gamma decay and the superallowed branching ratio for the beta(+) emitter (38)K(m).

The branching ratio for the superallowed beta(+) decay of (38)K(m) was measured at TRIUMF's ISAC radioactive ion beam facility. The M3 internal transition between the isomer and the ground state of (38)K(m) was observed with a branching ratio of 330(43) ppm. A search for the nonanalogue beta-decay branch to the first excited 0(+) state in (38)Ar was also performed and yielded an upper limit of < or =12 ppm at 90% C.

Precision branching ratio measurement for the superallowed beta+ emitter 62Ga and isospin-symmetry-breaking corrections in A>or=62 nuclei.

A high-precision branching ratio measurement for the superallowed beta+ decay of 62Ga was performed at the Isotope Separator and Accelerator radioactive ion beam facility. Nineteen gamma rays emitted following beta+ decay of 62Ga were identified, establishing the dominant superallowed branching ratio to be (99.861+/-0.

Daily changes in nitrate influx, efflux and metabolism in maize and pearl millet.

Maize (Zea mays L.) and pearl millet (Pennisetum americanum (L.) Leeke) seedlings were exposed to [(15)N]nitrate for 1-h periods at eight times during a 24-h period (16-8 h light-dark for maize; 14-10 h for millet).

The effect of waterlogging on the growth and ethylene content of Eucalyptus robusta Sm. (Swamp Mahogany).

When waterlogged over a period of 80 days plants of Eucalyptus robusta Sm. showed symptoms of leaf chlorosis, epinasty and premature abscission, reduction of stem elongation, stem hypertrophy and formation of adventitious shoots; chlorophyll content was reduced and soluble protein content of the upper leaves increased. Waterlogging doubled the rate of release of ethylene from roots and stems within 6 days, but had no effect on the ethylene concentration of leaves.

Litter fall and litter layer decay in coastal scrub at Sydney, Australia.

Seasonal litter fall and changes in dry weight and minerals within the litter layer were sampled throughout one year. The annual total litter fall was 4.9 t per hectare of which 70% was leaf fall.

Minerals and dry matter in coastal scrub and grassland at Sydney, Australia.

Two adjacent coastal ecosystems, dry sclerophyll scrub and introduced grassland, were sampled two (grassland) or three (scrub) times throughout one year to estimate total and component dry matter and mineral contents. The soil was the major mineral pool in both ecosystems and contained at least 60% of all minerals except potassium. The scrub live plus dead biomass amounted to 150 t ha of which half was below ground.

Daily changes in nitrate uptake and metabolism in Capsicum annuum.

The diurnal pattern of nitrate uptake by Capsicum annuum L. cv. California Wonder in a constant environment is described by a Fourier harmonic, with the maximum uptake in the middle of the photoperiod and the minimum in the middle of the dark period.

Photosynthate translocation in Capsicum annuum.

The leaves of Capsicum annuum L. cv. California Wonder function as efficient carbon exporting organs for a large part of their life span.

Daily changes in carbon-dioxide exchange and photosynthate translocation of leaves of Vicia faba.

Net carbon-dioxide exchange and loss of photosynthate-(14)C from leaves of Vicia faba L. were estimated throughout a day (16/8 h light/dark periods) by infrared gas analysis and Geiger-Müller-tube monitoring, respectively. Net photosynthesis reached 95% of the mean maximum rate within 1 h of the start of the photoperiod, and thereafter remained relatively constant before declining during the last 2-4 h of the photoperiod.
