We study the boundary behaviour of the Fefferman--Szegö metric and several associated invariants in a $C^\infty$-smoothly bounded strictly pseudoconvex domain.

This study aims to investigate the influence of yeast fermentation and inoculation methods on the quality of coffee across 3 different coffee cultivars. Fermenting Sacchoromyces cerevisiae SafAle s-33 on Coffea arabica cv. Caltimor via bucket inoculation outperforms spray inoculation across all aspects including microbial cell adhesion, the chemical profile, reducing sugar content and sensory analysis conducted by a Q-grader. The PCA analysis revealed distinct profiles of organic acids and volatile compounds in roasted beans in yeast fermentation and natural fermentation of all 3 coffee varieties. Particularly, volatile compounds such 1-(4-Methoxyphenyl)octan-1-one, 8-Oxabicyclo[3.2.1]oct-6-en-3-one and 5,6-Dimethoxy-2-(2-hydroxyethyl-1-thio)-3 trimethylsilyl methyl-1,4-benzoquinone and, furfuryl ethyl ether and 5-methyl furfural were detected only in yeast fermented bean. The malic acid also contained a higher amount in roasted coffee beans from the yeast fermentation of all 3 coffee varieties than the natural fermentation. Those compounds present a notably positive influence on the sensory aspects of the coffee i.e. sweet caramel, dry fruit, vanilla and hazelnut-like flavors. In addition, roasted beans from the yeast fermentation of C. arabica cv. Caltimor and C. canephora cv. Robusta displayed higher sensory scores when compared to those from natural fermentation, conversely in C. arabica cv. Bourbon, beans from both yeast fermentation and natural fermentation displayed similar quality levels. Our study concluded that the commercial yeast strain within the beer and wine industry proved to be an alternative source for coffee fermentation. Nevertheless, the selection of the coffee variety plays a crucial role when utilizing S. cerevisiae SafAle s-33 as a starter.

The COVID-19 pandemic has caused significant disruptions to healthcare student placements worldwide, including already challenged rural areas in Australia. While accounts are emerging of student experiences in larger centers and from a student perspective, there is a need for in-depth exploration of student supervisor experiences in rural areas at the onset of the pandemic. This study aims to address this gap through 23 individual, semi-structured interviews with healthcare workers from ten health professions who were either direct student supervisors or in roles supporting student supervisors A reflexive thematic analysis approach was used to develop four themes, namely compounding stress, negative impacts on student learning, opportunity to flex and innovate, and targeted transitioning support strategies. The findings indicate that healthcare workers with student supervision responsibilities at the onset of the pandemic experienced high levels of stress and wellbeing concerns. This study sheds light on the importance of supporting student supervisors in rural areas, and the need for implementing targeted support strategies for new graduates whose placements were impacted by the pandemic. This is not only essential for supporting the rural healthcare workforce but is also imperative for addressing inequalities to healthcare access experienced in rural communities.

Let U be the closed unit disc in C. We show that there is no continuous map F:U-->U^2, holomorphic on Int(U) and such that F(bU) = b(U^2).

It is founded the sufficient condition of Holder continuity of the ring $Q$-homeomorphisms in $\mathbb{R}^n, n\geq 2$ with respect to $p$-modulus at $n-1<p<n$.

We obtain growth estimates for the logarithmic derivative $B'(z)/B(z)$ of a Blaschke product as $|z| \to 1$ and $z$ avoids some exceptional sets.

Cartwright-type and Bernstein-type theorems, previously known only for functions of exponential type in $\C^n$, are extended to the case of functions of arbitrary order in a cone.

We give an example of a bounded Stein domain in $\mathbb{C}^n$, with smooth boundary, which is not Runge and whose intersection with every complex line is simply connected.
