Redeeming memories : a visual investigation into the lives of convict women
Creators: name: Henri, CJ
Publisher: name: University Of Tasmania
Year: 2023

description: This research explores the artist's role as an instigator, facilitator and advocate. By inviting members of the community to participate in an art project, the research project investigates art's potential for generating significant community engagement and facilitating shared cultural experience. In focusing on the subject of convict women, community participants have both reflected on and raised awareness of a history shrouded by a veil of amnesia. The project has involved the development of a large-scale installation, entitled Departures and Arrivals, individual components of which have been created by members of the public. The installation has been presented in general community settings in cities and towns around Tasmania and in Sydney. The sites chosen have been historic convict sites or art galleries, with the majority of the settings being outdoors. The subject-matter of Departures and Arrivals concerns the convict women of 19th century Van Diemen's Land and the extremely high death-rate, even for the time, among the babies of these women within the Cascades Female Factory at South Hobart. A combination of historical research and community involvement in art production has served to encourage reflection on the tragedy of the scores of deceased babies, the grief of their incarcerated mothers and the grim system to which they were all subjected - and the 'forgetting' that ensued through subsequent generations. The project has been informed by the philosophies and strategies of various contemporary artists whose work involves community engagement. Some, such as Vivienne Binns and Olafur Eliasson, involve members of the community in actual creative production. Others, whose work derives from socio-cultural concerns and who present their art in a variety of settings outside the formal gallery situation, include Julie Gough, Anne Ferran, Christian Boltanski, Sue Lorraine, Catherine Truman and Julie Blyfield. Traditional cotton is the principal medium employed in Departures and Arrivals. Consequently, artists have been studied who, likewise; have utilised cloth of various kinds as expressive media. These include Christo and Jeanne-Claude, Ann Hamilton and Kim Sooja. The thesis exhibition presents the major component of the installation, Departures and Arrivals: namely, some 1500 'bonnets'. It also includes documentation of the entire project as it has been undertaken in its various locations and lists of names, both of convict mothers and of their lost babies. As an objective of the exhibition is to encourage reflection and contemplation of particular local-historical events, it includes provision for public response, in particular feedback from individuals whose own family backgrounds may connect with those documented through the project. The research project has demonstrated the considerable potential of artist/community collaborations in addressing issues of a community's past: in this case, a painful and hitherto largely unknown aspect of Tasmania's convict history.

Semi-empirical formulation of multiple scattering for Gaussian beam model of heavy charged particles stopping in tissue-like matter
Creators: name: Kanematsu, Nobuyuki
Publisher: name: arXiv
Year: 2008
Subjects: subject: Medical Physics (physics.med-ph)
subject: FOS: Physical sciences

description: Dose calculation for radiotherapy with protons and heavier ions deals with a large volume of path integrals involving a scattering power of body tissue. This work provides a simple model for such demanding applications. There is an approximate linearity between RMS end-point displacement and range of incident particles in water, empirically found in measurements and detailed calculations. This fact was translated into a simple linear formula, from which the scattering power that is only inversely proportional to residual range was derived. The simplicity enabled analytical formulation for ions stopping in water, which was designed to be equivalent with the extended Highland model and agreed with measurements within 2% or 0.02 cm in RMS displacement. The simplicity will also improve the efficiency of numerical path integrals in the presence of heterogeneity.

Production values : re-discovering the hand in making
Creators: name: Mardon, S
Publisher: name: University Of Tasmania
Year: 2023

description: The versatility of clay lends itself to many applications and therefore, modes of ceramic production. With applications ranging from tableware, to sculpture and architecture, its history is deeply rooted in both tradition and industry. As a material, ceramic presents itself as the ideal medium with which to open up a discourse between these two areas, with particular focus on the qualities and corresponding values of the hand-made and machine-made object. The industrial revolution marked the separation of the hand from the making process. The changes in the method, scope, and scale of production are reflected in the objects and structures in our manufactured environment. In comparison, the hand-produced object is different from the industrial product, differently conceived, differently made, differently used. The values associated with the hand-made and hand skills have also changed in line with advances in technology. While industry may de-value the hand in making, there are qualities that resonate with us us they are inherently human. The questions underlying this research respond to the perceived loss of these qualities through a diminished relationship to materials and the making process. As consumers, we are also removed from the process due to systems of manufacture that are invisible to us, and through the removal of any visible character of the material or sign of the hand. The process is visible in the hand-made, however, in the traces left by the hand. This provides a connection to the object through an understanding of how it is made. The research involves a theoretical and practical investigation of ideas relating to the production of both hand and machine made objects. These ideas will be presented within a conceptual framework, with consideration towards functional applications. The practical component of the research explores the potential translation of hand-made qualities to the manufactured object. The outcomes suggest that we can reconnect the hand and mind with object making, by bringing attention to the 'material' qualities inherent in objects, and the sign of the hand, or machine, as an indication of process.

description: With increasing feasibility, long-read metagenomics can enable high-resolution taxonomic analysis in a range of applications from diagnostics to forensics. The ease of access via portable long-read platforms (e.g. MinION) is in contrast to the need for significant memory resources when classifiers try to provide precise reads assignments (to strain or sub-strain level) or identify a wider set of organisms (e.g. large eukaryotes). To address this, memory-efficient taxonomic classifiers are an active area of research, with methods based on compact indexes providing various tradeoffs between memory usage and speed.

Here we present a general-purpose strategy (PLoT-ME) that leverages the information in k-mer frequency (3-5bp) spectrums of long-reads to pre-classify them, allowing existing classifiers to further assign them against subsets of the reference database.

Evaluation on mock communities (real reads) shows that PLoT-ME’s fast K-means classifier provides a scalable, compact approach to rapidly pre-classify long error-prone reads (PacBio, Oxford Nanopore) without loss in classification performance. PLoT-ME was found to be robust to a range of read lengths (500bp-10kbp) and provides up to an order-of-magnitude reduction in memory requirements. We envisage that with further improvements in long-read metagenomic classifiers, this approach will enable a general-purpose strategy for high-resolution, low-memory microbiome analysis.
Spatial equilibrium analysis for Canadian apple production
Creators: name: Gilmor, Gary
Publisher: name: University of British Columbia
Year: 2011

description: The main purpose of this study was to examine aspects of interregional competition in fresh apple production in Canada. Two spatial equilibrium models, namely the transportation model and the supply-distribution model were used in establishing interregional trade patterns for fresh apples under given efficiency criteria, with major reference to the period July 1st. 1965 to June 30th 1966. The area studied included all of Canada which was disaggregated into supply and demand regions each having a representative point of origin. The transportation model comprised 9 domestic supply points, allowing for import points of entry, and 10 domestic demand points. The supply-distribution model utilized the four major apple producing regions in Canada together with three United States supply points, while maintaining the same 10 domestic demand points. The results of the study indicate that the Canadian fresh apple industry tends to be oriented around two distinct domestic market areas, one composed of the western provinces and the other the eastern provinces. Hence, British Columbia as a producing region for fresh apples can be identified mainly with all demand regions in the west as far as Winnipeg. In the east, the three major apple producing areas: Nova Scotia, Quebec and Ontario can be identified mainly with their own regional demand centres. With the inclusion of the three United States supply points in the analysis, the overall trading pattern did not undergo any significant change. Under two situations tested, no recommendation was made for shipment of fresh apples from a United States supply point to a Canadian demand point. Under the conditions assumed, therefore, production of fresh apples in the United States was not shown as meeting the competition in Canada from domestic producers. While the model incorporates several simplifying assumptions, the study produces new information on the competitive structure of Canadian fresh apple production. Furthermore, it would appear to exhibit methodological value in the sense that additional data accumulation and refinement would permit an even more penetrating analysis of interregional competition using the type of models already applied.
Building a text mining pipeline to retrieve literature to study stress response in Arabidopsis

description: Environmental stress factors, such a drought and heat, severely affect crop yield. Plants produce a wide variety of responses to endure environmental stress, such as change in rate of photosynthesis. Given the importance of this topic in agriculture, the number of studies is increasing, and so are the publications. Automatically mining information on plant genes and stress could greatly assist biologists conducting research in plant tolerance to stress. Thus, we have established a pipeline to integrate text mining methods to efficiently retrieve information on stress genes and their relation to function and processes in Arabidopsis. For this pipeline, we used Textpresso, ePMC annotations for gene ontology and GenRIF, and annotations provided by PubTator and pGenN. Upon initial review of 428 abstracts related to Arabidopsis genes and stress, we were able to identify 215 genes and related GO term biological processes from 197 of these. This exercise revealed pain points in the pipeline that need to be improved. In the future, we would like to extend this pipeline to plants in general and present the data in iTextMine to enable integration with relation extraction tools that may help highlight interesting aspects of the underlying biology.

description: Motivation: To facilitate biomedical text mining research on COVID-19, we have developed an automated, comprehensive named entity annotation and typing system CORD-NER. The system generates an annotated CORD-NER dataset based on the COVID-19 Open Research Dataset, covering 75 fine-grained types in high quality. Both the system and the annotated literature datasets will be updated timely.
Results: The distinctive features of this CORD-NER dataset include (1) it covers 75 fine-grained entity types: In addition to the common biomedical entity types (e.g., genes, chemicals and diseases), it covers many new entity types specifically related to the COVID-19 studies (e.g., coronaviruses, viral proteins, evolution, materials, substrates and immune responses), which may benefit research on COVID-19 related virus, spreading mechanisms, and potential vaccines; (2) it relies on distantly- and weakly-supervised NER methods, with no need of expensive human annotation on any articles or sub-corpus; and (3) its entity annotation quality surpasses SciSpacy (over 10% higher on the F1 score based on a sample set of documents), a fully supervised BioNER tool. Our NER system supports incrementally adding new documents as well as adding new entity types when needed by adding dozens of seeds as the input examples.

description: We derive the structural relations between nested harmonic sums and the corresponding Mellin transforms of Nielsen integrals and harmonic polylogarithms at weight {\sf w = 6}. They emerge in the calculations of massless single--scale quantities in QED and QCD, such as anomalous dimensions and Wilson coefficients, to 3-- and 4--loop order. We consider the set of the multiple harmonic sums at weight six without index $\{-1\}$. This restriction is sufficient for all known physical cases. The structural relations supplement the algebraic relations, due to the shuffle product between harmonic sums, studied earlier. The original amount of 486 possible harmonic sums contributing at weight {\sf w = 6} reduces to 99 sums with no index $\{-1\}$. Algebraic and structural relations lead to a further reduction to 20 basic functions. These functions supplement the set of 15 basic functions up to weight {\sf w = 5} derived formerly. We line out an algorithm to obtain the analytic representation of the basic sums in the complex plane.

description: We report the realization of superconductivity by 5d element Ir doping in LaFeAsO, a prototype parent compound of high-temperature iron based superconductors. X-ray diffraction patterns indicate that the material has formed the ZrCuSiAs-type structure with a space group P4/nmm. The systematic evolution of the lattice constants demonstrated that the Fe ions were successfully replaced by the Ir. Both electrical resistance and magnetization measurements show superconductivity up to 11 K in LaFe1-xIrxAsO. The superconducting transitions at different magnetic fields were also measured yielding a slope of -dHc2/dT = 6.7 T / K near Tc, and the upper critical field at zero K is found to be about 55 T. This is the first example of bulk superconductivity induced by replacing the Fe sites with higher d-orbital electrons in FeAs-1111 family, which should add more ingredients to the underlying physics of the iron-based superconductors.

Ce phénomène suscite un intérêt particulier chez les professionnels de santé qui ont à cœur de savoir comment les pères traversent ces moments de vie si particuliers afin de pouvoir répondre au mieux à leurs besoins. Objectifs : Le but de ce travail est, d’une part, de nous aider à comprendre ce que vivent les pères durant la grossesse de leur compagne, la naissance de leur enfant et le retour à domicile. Et d’autre part, il sensibilise les professionnels de santé sur les besoins des pères durant toute cette période périnatale et sur la meilleure façon d’y répondre. Méthodologie : Ce travail de Bachelor s’inscrit dans le cadre du projet de recherche « Naissance d’un père ». Il consiste à transcrire l2 entretiens vidéos. Un code book est ensuite établi afin de classer les données recueillies. Puis ces dernières sont analysées par le biais d’une méthode d’analyse thématique. Résultats et Conclusion : Tous les pères s’accordent à dire que l’arrivée d’un enfant dans un couple est un immense bouleversement, tant sur le plan personnel, que social ou professionnel. Tous ont su s’adapter aux changements, chacun à leur manière. C’est pour cela que les professionnels de santé doivent être vigilants quant aux ressentis des pères afin qu’ils puissent vivre cette délicate période le plus sereinement possible.

description: This work focuses on the fabrication and use of a Biological Micro-ElectroMechanical System (BioMEMS) for TeraHertz (THz) detection and characterization of enzymatic catalysis reactions. The fluidic microdevice was fabricated using traditional lithographic techniques. It was then functionalized by reactive amine functions using plasma polymerized allylamine (pp-allylamine), followed by enzyme immobilization inside the microchannels. The enzymatic reaction was controlled by fluorescent microscopy before being analysed by sub-THz spectroscopy in the frequency range 0.06--0.11 THz. The preliminary results show the feasibility of terahertz monitoring of the biocatalysis reaction.
Barotropic dynamic modelling of the Southern Indian Ocean : application to altimetry
Creators: name: Maraldi, CML
Publisher: name: University Of Tasmania
Year: 2023

description: The advent of satellite altimetry over the past decades has allowed global observation of the ocean with unique spatial and temporal coverage. These satellite data have had a profound impact on studies of the Southern Ocean, which is less well understood than other major oceans in the world. To allow the full exploitation of altimetric observations, any high frequency contribution has to be correctly accounted for. Tidal effects are the major component of the sea surface variability at high frequen-cies. Most of the ocean tide models are now consistent in the deep ocean at the centimetre level (LE PROVOST (2001)). The challenges for the new ocean tide models are to provide accurate solutions in shelf and coastal areas and at high latitudes, and especially beneath ice shelves, where large discrepancies between models still remain. The accurate know-ledge of the barotropic response of the ocean to the atmospheric forcing comes within the same scope of altimeter data investigation. The accuracy of high-frequency models depends essentially on the bathymetry, the model forcing terms and the temporal and spatial discretization of the model equations. With the aim of better characterizing the elevations due to high-frequency forcing, of better understanding the ocean model dynamics generated via these processes in the Southern Ocean region, especially beneath ice shelves, and of studying the impact of high-frequency dynamics on biological processes, we have put in place a regional model-ling study in the Southern Ocean. This region displays various geographical configura-tions : large plateaus open to the ocean, coastal areas, and the Amery Ice Shelf (AIS) cavity.

description: We present 24 new dense lightcurves of the near-Earth asteroids (3103) Eger, (161989) Cacus, (2100) Ra-Shalom and (12711) Tukmit, obtained with the Instituto Astrofísico Canarias 80 and Telescopio Abierto Remoto 2 telescopes at the Teide Observatory (Tenerife, Spain) during 2021 and 2022, in the framework of projects visible NEAs observations survey and NEO Rapid Observation, Characterization and Key Simulations. The shape models and rotation state parameters ($P$, $λ$, $β$) were computed by applying the lightcurve inversion method to the new data altogether with the archival data. For (3013) Eger and (161989) Cacus, our shape models and rotation state parameters agree with previous works, though they have smaller uncertainties. For (2100) Ra-Shalom, our results also agree with previous studies. Still, we find that a Yarkovsky - O'Keefe - Radzievskii - Paddack acceleration of $\upsilon = (0.223\pm0.237)\times10^{-8}$ rad d$^{-2}$ slightly improves the fit of the lightcurves, suggesting that (2100) Ra-Shalom could be affected by this acceleration. We also present for the first time a shape model for (12711) Tukmit, along with its rotation state parameters ($P=3.484900 \pm 0.000031$ hr, $λ= 27^{\circ}\pm 8^{\circ}$, $β= 9^{\circ} \pm 15^{\circ}$).

description: We present the recent results on non-photonic electron (NPE) yields from RHIC run8 p+p collisions. The $e/π$ ratio as a function of $p_T$ in run8 with a factor of 10 reduction of the inner detector material at STAR is found to be consistent with those results from run3 taking into account the NPE from charm leptonic decay and the difference of photonic electron yield from photon conversion in detector material. \Jpsi spectra in \pp and \cucu collisions at \sNN = 200 GeV with high sampled luminosity \Jpsi spectrum at high-\pT follows $x_T$ scaling, but the scaling is violated at low \pT. $J/ψ$-hadron correlations in \pp collisions are studied to understand the \Jpsi production mechanism at high $p_T$. We observed an absence of charged hadrons accompanying \Jpsi on the near-side, in contrast to the strong correlation peak in the di-hadron correlations. This constrains the $B$-meson contribution and jet fragmentation to inclusive \Jpsi to be ${}^{

description: We study a (1+1)-dimensional directed polymer in a random environment on the integer lattice with log-gamma distributed weights. Among directed polymers, this model is special in the same way as the last-passage percolation model with exponential or geometric weights is special among growth models, namely, both permit explicit calculations. With appropriate boundary conditions, the polymer with log-gamma weights satisfies an analogue of Burke's theorem for queues. Building on this, we prove the conjectured values for the fluctuation exponents of the free energy and the polymer path, in the case where the boundary conditions are present and both endpoints of the polymer path are fixed. For the polymer without boundary conditions and with either fixed or free endpoint, we get the expected upper bounds on the exponents.

В результате проведенной инженерно-технической экспертизы установлено, что трансформация микроструктуры стали в зоне термического влияния сварного соединения соответствует изменению температурного поля от нагретых кромок полосы при индукционной сварке трубной заготовки. Результаты механических испытаний свидетельствуют о равнопрочности основного металла и сварного соединения, которое подвергалось высокотемпературному нагреву и пластической деформации обжатием трубной заготовки при изготовлении баллона.
Disk masses in the embedded and T Tauri phases of stellar evolution

description: (Abridged). Motivated by a growing concern that masses of circumstellar disks may have been systematically underestimated by conventional observational methods, we present a numerical hydrodynamics study of time-averaged disk masses () around low-mass Class 0, Class I, and Class II objects. Mean disk masses (\overline{M}_d}) are then calculated by weighting the time-averaged disk masses according to the corresponding stellar masses using a power-law weight function with a slope typical for the Kroupa initial mass function of stars. Two distinct types of disks are considered: self-gravitating disks, in which mass and angular momentum are redistributed exclusively by gravitational torques, and viscous disks, in which both the gravitational and viscous torques are at work. We find that self-gravitating disks have mean masses that are slowly increasing along the sequence of stellar evolution phases. More specifically, Class 0/I/II self-gravitating disks have mean masses \overline{M}_d=0.09, 0.10, and 0.12 M_sun, respectively. Viscous disks have similar mean masses (\overline{M}_d=0.10-0.11 M_sun) in the Class 0/I phases but almost a factor of 2 lower mean mass in the Class II phase (\overline{M}_d,CII=0.06 M_sun). In each evolution phase, time-averaged disk masses show a large scatter around the mean value. Our obtained mean disk masses are larger than those recently derived by Andrews & Williams and Brown et al., regardless of the physical mechanisms of mass transport in the disk.

Gauge Field Theory of Horizontal Symmetry Generated by a Central Extension of the Pauli Algebra

description: The standard model of particle physics is generalized so as to be furnished with a horizontal symmetry generated by an intermediary algebra between simple Lie algebras $\mathfrak{su}(2)$ and $\mathfrak{su}(3)$. Above a certain high energy scale $\breveΛ$, the horizontal gauge symmetry is postulated to hold so that the basic fermions, quarks and leptons, form its fundamental triplets, and a triplet and singlet of the horizontal gauge fields distinguish generational degrees of freedom. A horizontal scalar triplet is introduced to make the gauge fields super-massive by breaking the horizontal symmetry at $\breveΛ$. From this scalar triplet, there emerge real scalar fields which do not interact with fermions except for neutrino species and may give substantial influence on evolution of the universe. Another horizontal scalar triplet which breaks the electroweak symmetry at a low energy scale $Λ\simeq 2\times 10^2$GeV reproduces all of the results of the Weinberg-Salam theory, produces hierarchical mass matrices with less numbers of unknown parameters in a unified way and predicts six massive scalar particles, some of which might be observed by the future LHC experiment.

Neonatal exposure to ultraviolet radiation : implications for development and function of the skin immune system
Creators: name: McGee, Heather Margaret
Publisher: name: University Of Tasmania
Year: 2023

description: Exposure to environmental stimuli, including viruses, bacteria and chemicals, during in early life has the capacity to influence the development of disease in adulthood. Presumably exposure to ultraviolet radiation would represent another of these environmental influences. Evidence for this comes from the observation that childhood exposure to sunburning doses of ultraviolet radiation is linked to an increased incidence of melanoma. Recently, laboratory studies have confirmed this relationship, but have been unable to elucidate the mechanism by which melanoma is increased. While numerous studies have demonstrated the significant impact that ultraviolet radiation has on function of the immune system in adults few studies have assessed its effects during the dynamic developmental state of the neonate. This thesis examines the short and long term effects of ultraviolet radiation on the development and function of the neonatal skin immune system. Initial experiments demonstrated a significant alteration in development of the Langerhans cell network of mice following one single exposure to ultraviolet B radiation. In addition, Langerhans cell function was altered, with a consequent skew in immunity away from the cell-mediated response required for tumour immunity. As such, this area warranted further study. A second model was devised in which Cleo Natural lamps emitting solar simulated ultraviolet radiation were utilised. One single exposure to the radiation from these lamps resulted in an arrest in Langerhans cell network development, despite a completely absent inflammatory response. When the contact hypersensitivity response was assessed eight weeks after exposure, there was a significant reduction in the ability to induce an effective response in mice irradiated as neonates. As such, exposure to either ultraviolet B radiation, or solar simulated ultraviolet radiation have the capacity to alter development of the immune response in mice. Remaining experiments focussed on identifying the mechanism by which the immune response was altered. Phenotypic studies identified an altered balance of lymph node cells in irradiated mice, with an increase in the number of T regulatory cells and altered B cell subsets. Functional studies suggested that these T regulatory cells were not the classical ultraviolet radiation induced T regulatory cells, but instead were likely to represent natural T regulatory cells. Results from this thesis have demonstrated a significant alteration in the structure and function of the immune system of mice, following one single exposure to ultraviolet radiation. This contributes to the existing literature, confirming the importance of the neonatal period in establishing immune function in adult life.

description:    Στην εργασία αυτή εξετάζεται το ζήτημα της ύπαρξης μεταποιητικών και μεταπαραγωγικών διαδικασιών στην αρχιτεκτονική και καλλιτεχνική σύνθεση. Σε μια εποχή ταχείας και συνεχούς παραγωγής πληροφορίας και εικόνας, κρίνεται αναγκαία η διαδικασία επανεξέτασης, επανερμηνείας του καλλιτεχνικού και αρχιτεκτονικού έργου με σκοπό την μεταπαραγωγή του, σε μια προσπάθεια διερεύνησης νέων νοημάτων, εικόνας και επικοινωνίας, αλλά και κατανόησης της σύγχρονης πραγματικότητας. Για την επίτευξη αυτού απαιτείται η χρήση τεχνικών μεταπαραγωγής, οι οποίες αντιτίθενται στην πολυτέλεια της αυτοματοποίησης της μαζικής παραγωγής και επανεξετάζουν το «ασήμαντο» και το «φτωχό» στοιχείο στην καλλιτεχνική και αρχιτεκτονική σύνθεση.
   Οι «φτωχές» τεχνικές, δεν είναι παρά ο συνδυασμός της αντίδρασης στην τυπική μορφή-ιδέα και της μεταποιητικής διαδικασίας. Αυτές εντοπίζονται στο έργο πολλών καλλιτεχνών από τον 19ο αιώνα έως και σήμερα, με επίκεντρο τις δεκαετίες ’60 και ’70.
   Με βάση τα παραπάνω αναλύεται το έργο και οι ιδέες του Ριζοσπαστικού Σχεδιασμού και της Φτωχής Τέχνης στον ιταλικό αρχιτεκτονικό και καλλιτεχνικό χώρο αυτών των δεκαετιών. Επιπλέον, παρουσιάζονται κοινές θεματικές των δύο αυτών κινημάτων, όπως η χειροτεχνία - crafting, η αντικουλτούρα - counterculture, το D.I.Y - «do it yourself» πνεύμα της εποχής, ο πρωτογονισμός καθώς και η οικολογία. Στην συνέχεια παρουσιάζεται η περίοδος 1970-1975, η οποία συγκεντρώνει καλλιτέχνες και αρχιτέκτονες της «φτωχής τεχνικής», που παράγουν έργο δημιουργώντας ένα είδος αντι-σχολής μέσα από εφήμερες δράσεις και κατασκευές.
   Μέσα από αυτές τις αναλύσεις παρουσιάζεται η άλλη όψη του ιταλικού design, δηλαδή του σχεδιασμού ως παράγωγο της κατασκευής και της τεχνικής και όχι αποκλειστικά της μηχανής. Συνολικά στόχος της εργασίας είναι να προβληθεί η σημασία των φτωχών τεχνικών στην συνθετική σκέψη και πράξη.
Fermentation of milk by Lactobacillus bifidus.
Creators: name: Brown, Charles Dwight
Publisher: name: University of British Columbia
Year: 2011

description: Bacteria, belonging to the Lactobacillus bifidus group, were isolated from rectal swabs obtained from healthy babies receiving breast milk. The fermentation properties of these bacteria in cow's milk were studied. Strains potentially suitable for fermentation in a food product were selected according to their ability to produce lactic acid and no gas from lactose, as well as adhering to characteristics common to the bifidus group (Gram positive, catalase negative and blanching morphology). The five strains chosen for intensive study produced 1.14 to 1.25% lactic acid and less than 0.05% volatile acid. The latter organisms could be cultured readily and coagulated milk in less than 24 hr when using a 5% inoculum. Repeated subculture resulted in a change from the branched to the unbranched bacterial morphology. This transformation, which is not unusual among bifid bacteria, was accompanied by a change in ability to produce lactic acid, but no gas was produced by branched or unbranched strains. A great deal of variability in morphology, growth consistency, and acid production was observed among the more than 500 bacterial strains isolated. However, the bifid populations from Caucasian babies was not noticeably different from those of native Indian babies. All of the five strains selected utilized inulin, dextrin, mannitol, and melezitose. A 24 hr culture of fermented milk yielded a product with a mild pleasant natural flavour which could conceivably be altered, if desired, by adding sweeteners or flavouring agents
