Wine making in small quantities
This publication aims to guide the amateur wine maker producing small quantities of wine from fresh grapes. It does not explain the changes that occur when grape juice is fermented into wine, nor does it discuss the technology required to make commercial quantities of wine.https://researchlibrary.agric.wa.gov.au/bulletins/1257/thumbnail.jp
Visual art inspired by the collective feeding behavior of sand-bubbler crabs
Sand--bubblers are crabs of the genera Dotilla and Scopimera which are known
to produce remarkable patterns and structures at tropical beaches. From these
pattern-making abilities, we may draw inspiration for digital visual art. A
simple mathematical model is proposed and an algorithm is designed that may
create such sand-bubbler patterns artificially. In addition, design parameters
to modify the patterns are identified and analyzed by computational aesthetic
measures. Finally, an extension of the algorithm is discussed that may enable
controlling and guiding generative evolution of the art-making process
Introduction : translingual work.
This issue both reflects and builds on the efforts prompted by the 2011 College English essay âLanguage Difference in Writing: Toward a Translingual Approach,â by Bruce Horner, Min-Zhan Lu, Jacqueline Jones Royster, and John Trimbur. Contributions to this symposium contextualize the emergence of a translingual approach, explore the tension and interconnections between a translingual approach and a variety of fields, and explore the viability of a translingual approach in light of existing academic structures
Chemoresistive Gas Sensor based on SiC Thick Film: Possible Distinctive Sensing Properties Between H2S and SO2â
Commercially available nanosized powder of silicon carbide (named SiC), was thermally, morphologically and structurally characterized. After that, it was screen-printed onto alumina substrates in order to obtain thick films to be tested as functional material for conductometric gas sensors. Samples were exposed to SO2 and H2S, gases with high importance in many application fields, with the aim of verifying its capability of distinguishing between them. The characterization highlighted that this semiconductor type is selective for sulphur dioxide (SO2), in concentrations within the ppm range. This interesting result was found at high temperatures (600-800°C), useful for harsh environmental, and the measurements proved to be completely free from humidity interference. Applications of such a sensor could span many fields, since SO2 plays an important role in air pollution, industrial processes and wine making monitoring
Effect of plasma activated water (PAW) on rocket leaves decontamination and nutritional value
Plasma Activated Water (PAW) obtained by exposing water to cold atmospheric pressure plasma, has recently emerged as a promising alternative for food decontamination, compared to the use of traditional chemical sanitizers. The aim of the study was to evaluate the efficacy of PAW treatments for rocket salad decontamination. Washing with PAW for 2, 5, 10 and 20 min was assessed against different endogenous spoilage microorganisms and compared to untreated water and hypochlorite solution. The chemical composition of PAW as a function of treatment and delay time was characterized and the effect on product quality and nutritional parameters was evaluated. Results showed that PAW allowed an average reduction of 1.7â3 Log CFU/g for total mesophilic and psychrotrophic bacteria and Enterobacteriaceae following 2â5 min washing with minimal variation of qualitative and nutritional parameters. Overall, experimental results highlighted the potentiality of PAW treatments as a promising alternative to chlorine having the advantage of a minor adverse impact on environment and consumers' health. Industrial relevance: To meet consumers demand, the minimally processed fruit and vegetable industry needs to find sustainable solutions as alternative to the use of traditional chemical sanitizers that allow to increase product shelf-life and preserve safety, qualitative and nutritional characteristics. Plasma activated water represents a promising strategy for food decontamination, but its effects on foods have been only limitedly investigated. The present research is the first study on the use of plasma activated water on fresh rocket leaves, providing new and important information on microbial inactivation and quality of the fresh cut product
Understanding Interorganizational Learning Based on Social Spaces and Learning Episodes
Different organizational settings have been gaining ground in the world economy, resulting in a proliferation of
different forms of strategic alliances that translate into a growth in the number of organizations that have started
to deal with interorganizational relationships with different actors. These circumstances reinforce Crossan, Lane,
White and Djurfeldt (1995) and Crossan, Mauer and White (2011) in exploring what authors refer to as the
fourth, interorganizational, level of learning. These authors, amongst others, suggest that the process of
interorganizational learning (IOL) warrants investigation, as its scope of analysis needs widening and deepening.
Therefore, this theoretical essay is an attempt to understand IOL as a dynamic process found in
interorganizational cooperative relationships that can take place in different structured and unstructured social
spaces and that can generate learning episodes. According to this view, IOL is understood as part of an
organizational learning continuum and is analyzed within the framework of practical rationality in an approach
that is less cognitive and more social-behavioral
Articulating practice through the interview to the double
The paper aims to realise the critical potential of the practice lens by contributing to the
development of a coherent set of methodologies for investigating work and
organisational activity. It does so by introducing and critically assessing the "interview
to the double" as a method to articulate and represent practice.
After briefly illustrating its history and usage, the paper analyses in depth the setting
generated by this unusual interview method. It argues that the nature of the encounter
produces narratives that are often morally connoted and idealised in character. As a
consequence the method is especially useful to capture the going concerns which orient
the conduct of the members and the normative and moral dimension of practice. The
paper also shows that because it mimics familiar instruction-giving discursive practices,
the method constitutes an effective textual device to convey this moral and normative
dimension in a way which remains faithful to its situated and contingent nature of
practice
Redefining innovation processes: The digital designers at work
As design in digital innovation has become a thing, we highlight the inconclusive concepts that describe design activity in innovation processes. Proposing an alternative theoretical lens - a sociomaterial practice lens - we claim that this view can reveal the contribution of digital designers to the work of innovation. This paper draws on a research study with digital designers in the UK. At the same time as we begin to reconceptualise the ways digital design activity can be described, we also illustrate a theoretical framework based on 1) action and knowing as ordered by collectively produced objects, 2) sociomateriality and the configuration of human bodies and materials in action, 3) the co-emergence of objects and sociomaterial configurations where each is the condition of the other. This alternative way of looking at design activity may pose some challenges to the theoretical traditions in the field. We however believe that it contains immense potential too
IL-12 and GM-CSF in DNA/MVA Immunizations against HIV-1 CRF12_BF Nef Induced T-Cell Responses With an Enhanced Magnitude, Breadth and Quality
In Argentina, the HIV epidemic is characterized by the co-circulation of subtype B and BF recombinant viral variants. Nef is an HIV protein highly variable among subtypes, making it a good tool to study the impact of HIV variability in the vaccine design setting. We have previously reported a specific cellular response against NefBF with low cross-reactivity to NefB in mice. The aim of this work was to analyze whether the co-administration of IL-12 and GM-CSF, using DNA and MVA vaccine vectors, could improve the final cellular response induced. Mice received three DNA priming doses of a plasmid that express NefBF plus DNAs expressing IL-12 and/or GM-CSF. Afterwards, all the groups were boosted with a MVAnefBF dose. The highest increase in the magnitude of the NefBF response, compared to that induced in the control was found in the IL-12 group. Importantly, a response with higher breadth was detected in groups which received IL-12 or GM-CSF, evidenced as an increased frequency of recognition of homologous (BF) and heterologous (B) Nef peptides, as well as a higher number of other Nef peptide pools representing different viral subtypes. However, these improvements were lost when both DNA cytokines were simultaneously administered, as the response was focused against the immunodominant peptide with a detrimental response towards subdominant epitopes. The pattern of cytokines secreted and the specific-T-cell proliferative capacity were improved in IL-12 and IL-12+GM-CSF groups. Importantly IL-12 generated a significant higher T-cell avidity against a B heterologous peptide
