Enzyme

description: Natural products produced by microorganisms and plants provide a rich source of novel and diverse chemical entities. Understanding the biosynthetic pathways of these natural products and the chemical mechanisms of the enzymes involved has been essential for modern drug discovery and development. This dissertation describes studies on the biosynthetic pathways of natural products with atypical chemical motifs. Part I describes biosynthetic studies of the lincosamides and albomycins, which are two groups of thiosugar-containing natural products. Lincosamides such as lincomycin A and celesticetin share a thioglycoside core linked to a proline residue but contain different substituents on the sulfur center at C1. It will be demonstrated that three stand-alone nonribosomal peptide synthetase domains are responsible for conjugation between the proline residue and the thiosugar core. In addition, the pyridoxal 5′- phosphate-dependent enzymes LmbF and CcbF are shown to be key enzymes that lead to bifurcation of the lincosamide biosynthetic pathway and differential modification of lincomycin A versus celesticetin. Albomycins are 4′-thiofuranose-containing nucleosides that are conjugated with a ferrichrome-type siderophore through a serine linker residue. It will be shown that AbmM catalyzes formation of the sulfur-bridged furanose core via a radical-mediated mechanism. In addition, it will also be demonstrated that the resulting 4′-thiofuranosyl nucleotide is matured into SB-217452, which is the active antibiotic component of albomycins, via reactions catalyzed by AbmG, AbmH, AbmD, AbmK, AbmF, and AbmJ. Part II describes mechanistic studies of hyoscyamine 6β-hydroxylase (H6H). H6H catalyzes hydroxylation and subsequent oxidative cyclization to form an epoxide ring from an ethylene group during scopolamine alkaloid biosynthesis. Studies using substrate analogues indicate that substrate conformation correlates with selectivity between the dihydroxylation and epoxidation activities of H6H. Based on kinetic analysis, it will also be shown that the presence of a hydroxyl group in the substrate significantly affects the regioselectivity of H atom abstraction during H6H-catalyzed oxidation reactions.

description: This paper presents a novel approach to create an RDF based e-version of the correspondence network by connecting author-centric digital editions platforms without centeralizing data silos. Through one single platform that presents the network, researchers can perform advanced metadata and asynchronous full-text queries over the entire network to find resources for their research inventory and directly access the data. The advanced search tools of the platform, allow researchers to channel their expertise into the analysis of the resources and their relations rather than a quest for them. Based on this work, this paper introduces a new research method, The Network Method, to study the historical data as a graph. It also argues that visualization of the RDF based network of correspondence as web-based interactive 3D force-directed graphs empowers relational thinking by depicting the connections between resources and drawing the researcher's attention to the connection between the atoms of knowledge, data distribution, irregularities, etc. Furthermore, this paper presents a new feature that adds the time-dimension to the visualization of the correspondence data which enables researchers to study the change in the topic of correspondence over time.

description: A metric that describes a collapsing star and the surrounding black hole geometry accounting for quantum gravity effects has been derived independently by different research groups. There is consensus regarding this metric up until the star reaches its minimum radius, but there is disagreement about what happens past this event. The discrepancy stems from the appearance of a discontinuity in the Hamiltonian evolution of the metric components in Painlevé-Gullstrand coordinates. Here we show that the continuous geometry that describes this phenomenon is represented by a discontinuous metric when written in these coordinates. The discontinuity disappears by changing coordinates. The discontinuity found in the Hamiltonian approach can therefore be interpreted as a coordinate effect. The geometry continues regularly into an expanding white hole phase, without the occurrence of a shock wave caused by a physical discontinuity.

description: Fire resistance of timber structures is mainly investigated by ISO 834 standard fire resistance tests. In the tests, specimens are heated in accordance with prescribed standard time-temperature curve and the time to failure is measured, but no information is available with regard to the behaviours during post-heating period. In case of timber constructions, post-heating behaviour is important because the self-burning continues during cooing period. To investigate the behaviour during cooling period, fire resistance tests of larch GLT (Glue Laminated Timber) walls were carried out. The wall thickness was 100mm. The walls were heated in accordance with ISO 834 for 60 minutes. After heating, the furnace was supplied with fresh air at various rates. By changing the air supply rate, 8 experiments were carried out. Behaviours, such as self-burning, were observed and recorded by video. Heat release rates by self-burning was measured by the oxygen consumption technique. Time-dependent temperature and water content values were measured at internal points of the specimen. As a result, the post-heating self-burning behaviour depended on the rate of air supply. In case of large air supply rate, self-burning was intense right after the end of heating. However, the self-burning ceased fairly quickly because the furnace was cooled down rapidly due to the large amount of supplied air. In case of small air supply rate, self-burning was relatively mild because the oxygen is not enough. However, the decrease of furnace temperatures was slow because the air supply rate was small. As a result, charring of specimen was deeper as the air supply rate was smaller.

description: The Haldane model on the honeycomb lattice is a paradigmatic example of a Hamiltonian featuring topologically distinct phases of matter. It describes a mechanism through which a quantum Hall effect can appear as an intrinsic property of a band-structure, rather than being caused by an external magnetic field. Although an implementation in a material was considered unlikely, it has provided the conceptual basis for theoretical and experimental research exploring topological insulators and superconductors. Here we report on the experimental realisation of the Haldane model and the characterisation of its topological band-structure, using ultracold fermionic atoms in a periodically modulated optical honeycomb lattice. The model is based on breaking time-reversal symmetry as well as inversion symmetry. The former is achieved through the introduction of complex next-nearest-neighbour tunnelling terms, which we induce through circular modulation of the lattice position. For the latter, we create an energy offset between neighbouring sites. Breaking either of these symmetries opens a gap in the band-structure, which is probed using momentum-resolved interband transitions. We explore the resulting Berry-curvatures of the lowest band by applying a constant force to the atoms and find orthogonal drifts analogous to a Hall current. The competition between both broken symmetries gives rise to a transition between topologically distinct regimes. By identifying the vanishing gap at a single Dirac point, we map out this transition line experimentally and quantitatively compare it to calculations using Floquet theory without free parameters. We verify that our approach, which allows for dynamically tuning topological properties, is suitable even for interacting fermionic systems. Furthermore, we propose a direct extension to realise spin-dependent topological Hamiltonians.

description: In this work we apply the density matrices approach to orbital ordering (OO) in order to study the OO of the spinel vanadates AV$_{2}$O$_{4}$ (A $\equiv$ Zn, Cd and Mg), which is normally believed to be responsible for the structural transition from cubic to tetragonal phase observed in these compounds. The density matrices of vanadium atoms are obtained by using {\it state-of-the-art} full-potential linearized augmented plane wave method based GGA+U calculations. In the absence of spin-orbit coupling, the present study shows the existence of anti-ferro OO in the global (local octahedral) coordinate system where $d_{xz}$ and $d_{yz}$ ($d_{xz}$+$d_{yz}$ and $d_{xz}$-$d_{yz}$) orbitals are mainly occupied at the neighboring V sites for all the compounds.

description: MeV nuclear de-excitation lines serve as a unique tool to study low-energy cosmic rays (CRs), containing both spectral and elemental information of the interacting material. In this paper, we estimated the possible nuclear de-excitation lines from the young supernova remnant Cassiopeia A. Given different CR spectral shapes and interacting materials, we found the predicted fluxes of strong narrow line emissions from the remnant are highly model-dependent, ranging from about $1\times10^{-10}\,{\rm \,cm^{-2}\,s^{-1}}$ to $1\times10^{-6}\, {\rm \,cm^{-2}\,s^{-1}}$ for the 4.44 MeV narrow line and from about $4\times10^{-11}\,{\rm \,cm^{-2}\,s^{-1}}$ to $2\times10^{-7}{\rm \,cm^{-2}\,s^{-1}}$ for the 6.13 MeV narrow line, respectively. Based on the new estimation, we also discussed the detection probability of these line emissions against the MeV diffuse Galactic background under different assumptions of instrument response functions.

INSERTION (CO)POLYMERIZATION OF OLEFINS CATALYZED BY FIRST ROW TRANSITION METAL COMPLEXES
Creators: name: ZANCHIN, GIORGIA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: Since polyolefins are an integral part of everyday life and given the ever-growing global demand for these polymers, the insertion polymerization of olefins is one of the most industrially relevant synthetic reaction, widely investigated also in academia. It is in this context that this PhD project is located. The developed research activity was aimed at synthesizing new catalytic systems capable of stereochemically drive the polymerization of various (di)olefins, in particular cyclic olefins such as norbornene and its derivatives. The investigated catalysts are made up of two components: the organometallic complex (pre-catalyst) and an aluminum alkyl compound (co-catalyst or activator). Among the series of the organometallic complexes, during my PhD, complexes of the first row transition metals, i.e., titanium, vanadium, and chromium, bearing nitrogen and phosphorous based ligands were investigated. They were later applied as catalysts for the homopolymerization of ethylene, cyclic olefins (norbornene, dicyclopentadiene and norbornene derivatives) and 1,3-butadiene, and the copolymerization of ethylene with various cyclic olefins. Depending on the employed catalyst and the polymerization conditions, we obtained oligomers or high-polymers. All the products were carefully characterized with different techniques, in order to get more information on the properties of the obtained (co)polymers as well as on the polymerization mechanism. Norbornene and dicyclopentadiene oligomers were mainly obtained from titanium and chromium catalysts, activated by Et2AlCl and methylalumoxane (MAO), respectively, while cyclic olefin copolymers were obtained from the copolymerization of ethylene with cyclic olefins promoted by vanadium based catalysts. In addition, we demonstrated that some vanadium and chromium complexes, in combination with MAO, were active in the polymerization of 1,3-butadiene, affording poly(1,3-butadiene) with different microstructure (cis-1,4, trans-1,4 or 1,2) and stereospecificity (i.e., iso- or syndiotactic polymers), depending on the type of ligand. This study allowed to understand the correlations between the catalyst?s features and the polymerization outcome in terms of activity, regio- and stereoselectivity. Moreover, particular emphasis has been devoted to the study of the catalyst stability over the polymerization time and temperature. At the same time, particular interest has been developed toward the post?polymerization functionalization, as a strategy to modify some polymer properties (e.g., solubility and processability) and thus to obtain polymers hardly obtainable by direct (co)polymerization with polar (co)monomers. This PhD dissertation reports the results achieved during the three-year research activity, together with the main difficulties encountered and the actions put in place trying to overcome them.

description: Angiogenesis involves the formation of new blood vessels by sprouting or splitting of existing blood vessels. During sprouting, a highly motile type of endothelial cell, called the tip cell, migrates from the blood vessels followed by stalk cells, an endothelial cell type that forms the body of the sprout. To get more insight into how tip cells contribute to angiogenesis, we extended an existing computational model of vascular network formation based on the cellular Potts model with tip and stalk differentiation, without making a priori assumptions about the differences between tip cells and stalk cells. To predict potential differences, we looked for parameter values that make tip cells (a) move to the sprout tip, and (b) change the morphology of the angiogenic networks. The screening predicted that if tip cells respond less effectively to an endothelial chemoattractant than stalk cells, they move to the tips of the sprouts, which impacts the morphology of the networks. A comparison of this model prediction with genes expressed differentially in tip and stalk cells revealed that the endothelial chemoattractant Apelin and its receptor APJ may match the model prediction. To test the model prediction we inhibited Apelin signaling in our model and in an \emph{in vitro} model of angiogenic sprouting, and found that in both cases inhibition of Apelin or of its receptor APJ reduces sprouting. Based on the prediction of the computational model, we propose that the differential expression of Apelin and APJ yields a "self-generated" gradient mechanisms that accelerates the extension of the sprout.

description: Previous theoretical works using the pre-merger orbital evolution of coalescing neutron stars to constrain properties of dense nuclear matter assume a gravitational wave phase uncertainty of a few radians, or about a half cycle. However, recent studies of the signal from GW170817 and next generation detector sensitivities indicate actual phase uncertainties at least twenty times better. Using these refined estimates, we show that future observations of nearby sources like GW170817 may be able to reveal neutron star properties beyond just radius and tidal deformability, such as the matter composition and/or presence of a superfluid inside neutron stars, via tidal excitation of g-mode oscillations. Data from GW170817 already limits the amount of orbital energy that is transferred to the neutron star to <2x10^47 erg and the g-mode tidal coupling to Qmode<10^-3 at 50 Hz (5x10^48 erg and 4x10^-3 at 200 Hz), and future observations and detectors will greatly improve upon these constraints. In addition, analysis using general parameterization models that have been applied to the so-called p-g instability show that the instability already appears to be restricted to regimes where the mechanism is likely to be inconsequential; in particular, we show that the number of unstable modes is <<100 at <~100 Hz, and next generation detectors will essentially rule out this mechanism (assuming that the instability remains undetected). Finally, we illustrate that measurements of tidal excitation of r-mode oscillations in nearby rapidly rotating neutron stars are within reach of current detectors and note that even non-detections will limit the inferred inspiralling neutron star spin rate to <20 Hz, which will be useful when determining other parameters such as neutron star mass and tidal deformability.

description: The present paper features the adaptation of an existing Big Five questionnaire with a rating scale (RS) response format into a measure using a multidimensional forced choice (MFC) response format. Rating scale response formats have been criticized for their proneness to intentional and unintentional response distortions. Multidimensional forced choice response formats were suggested as a solution to mitigate several types of response sets and response styles by design. The Big Five Inventory of Personality in Occupational Situations (B5PS) is a situation-based questionnaire designed for personnel selection and development purposes which would benefit from fake-proof response formats. MFC response formats require special effort during test construction and calibration which will be laid out here. Changing the response format has severe consequences on item design and scoring. An inherent issue with MFC formats derives from their inability to yield interpersonal comparative results from standard (sum) scoring. This issue can be solved with item response theory (IRT)-based calibration during test construction. The Thurstonian IRT approach (TIRT) was developed by Brown and Maydeu-Olivares (2011), and aspects of MFC item design and TIRT calibrations are explored in this paper. Evidence on structural and construct validity are presented alongside recommendations on the test development processes. The results support the feasibility of the concept of MFC test construction with TIRT calibration in a contextualized and situation-based item format.

description: Integrable systems are derived from inelastic flows of timelike, spacelike, and null curves in 2- and 3- dimensional Minkowski space. The derivation uses a Lorentzian version of a geometrical moving frame method which is known to yield the modified Korteveg-de Vries (mKdV) equation and the nonlinear Schrodinger (NLS) equation in 2- and 3- dimensional Euclidean space, respectively. In 2-dimensional Minkowski space, timelike/spacelike inelastic curve flows are shown to yield the defocusing mKdV equation and its bi-Hamiltonian integrability structure, while inelastic null curve flows are shown to give rise to Burgers' equation and its symmetry integrability structure. In 3-dimensional Minkowski space, the complex defocusing mKdV equation and the NLS equation along with their bi-Hamiltonian integrability structures are obtained from timelike inelastic curve flows, whereas spacelike inelastic curve flows yield an interesting variant of these two integrable equations in which complex numbers are replaced by hyperbolic (split-complex) numbers.

description: Optical flow and disparity are two informative visual features for autonomous driving perception. They have been used for a variety of applications, such as obstacle and lane detection. The concept of "U-V-Disparity" has been widely explored in the literature, while its counterpart in optical flow has received relatively little attention. Traditional motion analysis algorithms estimate optical flow by matching correspondences between two successive video frames, which limits the full utilization of environmental information and geometric constraints. Therefore, we propose a novel strategy to model optical flow in the collision-free space (also referred to as drivable area or simply freespace) for intelligent vehicles, with the full utilization of geometry information in a 3D driving environment. We provide explicit representations of optical flow and deduce the quadratic relationship between the optical flow component and the vertical coordinate. Through extensive experiments on several public datasets, we demonstrate the high accuracy and robustness of our model. Additionally, our proposed freespace optical flow model boasts a diverse array of applications within the realm of automated driving, providing a geometric constraint in freespace detection, vehicle localization, and more. We have made our source code publicly available at https://mias.group/FSOF.

Même s’il est illusoire de penser qu’il serait possible d’éviter toute transmission d’informations erronées, il est du devoir de l’enseignant d’éviter ces cas de figure au maximum. L’analyse critique d’informations et de données, des tests pratiques, mais aussi le suivi des avancées de la science peuvent permettre la détection d’informations scientifiques fausses et ainsi éviter que ces dernières ne soient transmises par l’enseignement. Les enseignants, peuvent discuter de leurs interrogations et débattre au sein de la file (de biologie). Ils peuvent parler entre collègues et profiter des spécialités de chacun, chercher à valider une « théorie » en cherchant avec les élèves, proposer ces thèmes comme travaux personnels ou travaux de maturité, mais aussi utiliser la ressource des universités à proximité Par une analyse de la situation actuelle des représentations qui existent sur la carte de la langue (carte du goût), il en est ressorti qu’une majorité des élèves et étudiants-enseignants pensent que la carte de la langue telle que créé à partie des travaux de Boring (Boring, 1942) est correcte. Alors même que dès 1974 (et confirmé par d’autres travaux plus tard), il a été établi que cette information était fausse (Collings, 1974). De plus, même après avoir été informés pendant un cours à propos des idées ou informations fausses en sciences avec une partie de cours (à la HEP Vaud) dédié à la carte de la langue, les sujets gardent pour une majorité la conviction que la carte de la langue avec des zones exclusives (ou presque) des goûts donnés serait correcte.

Diese Menschen kommen in verschiedenen Kontexten mit Sozialtätigen in Berührung. Die vorliegende Bachelor-Arbeit mit dem Titel «Unterstützung der Integration von geflüchteten Menschen mit psychischen Leiden durch die Soziale Arbeit» verfolgt anhand von Fachliteratur das Ziel, Sozialtätige auf die Thematik der psychischen Gesundheit im Integrationsprozess von geflüchteten Menschen zu sensibilisieren und auszurüsten. Die gewonnen Erkenntnisse zeigen, dass die Integration von Geflüchteten mit psychischen Störungen durch einige Risiken erschwert werden. Zum einen besteht das Risiko, dass Symptome von psychischen Störungen von den beteiligten Personen übersehen, missverstanden oder verharmlost werden. Zum anderen können Symptome zwar von den Beteiligten erkannt und einigermassen richtig eingeordnet werden, allerdings kann trotzdem das Risiko bestehen, dass die Thematik durch zu wenige Ressourcen nicht angegangen wird. Laut der Autorin Franziska Pinto Ramos können Störungssymptome und Betreuungsbedarf bei Erkennung durch Sozialtätige zu Gunsten der Integration mit Hilfe der Sozialen Diagnostik, medizinischen und psychotherapeutischen Fachpersonen, traumasensiblen Grundprinzipien und Fachkenntnissen zu den spezifischen Störungsbildern in der Arbeit der Sozialtätigen bearbeitet werden.

description: The degree spectrum of a countable structure is the set of all Turing degrees of presentations of that structure. We show that every nonlow Turing degree lies in the spectrum of some differentially closed field (of characteristic 0, with a single derivation) whose spectrum does not contain the computable degree 0. Indeed, this is an equivalence, for we also show that every such field of low degree is isomorphic to a computable differential field. Relativizing the latter result and applying a theorem of Montalban, Soskova, and Soskov, we conclude that the spectra of countable differentially closed fields of characteristic 0 are exactly the jump-preimages of spectra of automorphically nontrivial countable graphs.
Hochsensibilität im Kontext der Sozialen Arbeit: Bedeutung von prekären Arbeitsbedingungen und des betrieblichen Gesundheitsmanagements in stationären Institutionen

description: Fachpersonal in stationären Institutionen ist mit psychischer Belastung konfrontiert. Es ist Bindungsmustern, welche von der Norm abweichen, und traumatischen Übertragungen ausgesetzt, welche zu Sekundärtraumatisierungen führen können. Burnout und Depression sind weitere Folgen von psychischer Belastung, wenn diese nicht frühzeitig erkannt werden. Institutionen sind aufgefordert, die Gesundheit ihrer Mitarbeitenden zu wahren. Im historischen Kontext der Sozialen Arbeit hat die Vernachlässigung der Gesundheit der Fachpersonen zu Missständen und schwarzer Pädagogik geführt. Prekäre Arbeitsbedingungen beeinflussen die Gesundheit der Arbeitnehmenden in einem Betrieb. Dies äussert sich negativ bei der Arbeit mit einer traumatisierten Klientel, die auf eine sichere Umgebung angewiesen ist. Traumapädagogische Werte und Haltungen dienen dazu, eine Klientel mit negativen Lebenserfahrungen, welche sich traumatisierend auf sie ausgewirkt haben, zu stabilisieren. Für diese Arbeit sind gesunde Fachpersonen zwingend notwendig. In dieser Arbeit wird die Bedeutung prekärer Arbeitsbedingungen und eines positiven betrieblichen Gesundheitsmanagements für hochsensibel-begabte Fachpersonen in stationären Settings aufgezeigt. Aspekte auf Mikro- und Mesoebene verdeutlichen Diskrepanzen in Bezug auf die Professionalität von Fachpersonen, wenn sie durch prekäre Arbeitsbedingungen gesundheitlich negativ beeinflusst werden. Wie in der Traumapädagogik ist eine sichere Umgebung für die positive Entwicklung der Klientel essenziell. Betriebliches Gesundheitsmanagement bildet ein Fundament, um eine solche Umgebung zu schaffen. Dieses Fundament ist Grundlage für traumapädagogische Arbeit.

description: The launch of NASA's Kepler space telescope in 2009 revolutionized the quality and quantity of observational data available for asteroseismic analysis. While Kepler was able to detect solar-like oscillations in hundreds of main-sequence and subgiant stars, the Transiting Exoplanet Survey Satellite (TESS) is now making similar observations for thousands of the brightest stars in the sky. The Asteroseismic Modeling Portal (AMP) is an automated and objective stellar model-fitting pipeline for asteroseismic data, which was originally developed to use models from the Aarhus Stellar Evolution Code (ASTEC). We briefly summarize an updated version of the AMP pipeline that uses Modules for Experiments in Stellar Astrophysics (MESA), and we present initial modeling results for the Sun and several solar analogs to validate the precision and accuracy of the inferred stellar properties.

description: The Loewner equation provides a correspondence between continuous real-valued functions $λ_t$ and certain increasing families of half-plane hulls $K_t$. In this paper we study the deterministic relationship between specific analytic properties of $λ_t$ and geometric properties of $K_t$. Our motivation comes, however, from the stochastic Loewner equation (SLE$_κ$), where the associated function $λ_t$ is a scaled Brownian motion and the corresponding domains $\mathbb{H} \backslash K_t$ are Hölder domains. We prove that if the increasing family $K_t$ is generated by a simple curve and the final domain $\mathbb{H} \backslash K_T$ is a Hölder domain, then the corresponding driving function has a modulus of continuity similar to that of Brownian motion. Informally, this is a converse to the fact that SLE$_κ$ curves are simple and their complementary domains are Hölder, when $κ< 4$. We also study a similar question outside of the simple curve setting, which informally corresponds to the SLE regime $κ> 4$. In the process, we establish general geometric criteria that guarantee that $K_t$ has a Lip$(1/2)$ driving function.

description: L’évaluation sommative ne représente qu’une étape dans le processus d’apprentissage et d’évaluation des élèves, mais elle est lourde en termes d’enjeux pédagogiques. En effet, la sélection opérée par les institutions scolaires s’opère principalement sur la base de notes attribuées aux élèves à travers de telles évaluations. Au vu de l’actuelle omniprésence de cellesci dans le parcours des jeunes en formation, on peut aisément comprendre comment celles-ci peuvent devenir si anxiogènes. Elles finissent alors par faillir à leur mission, servir de prises d’informations permettant de favoriser les apprentissages, au profit de leur fonction de classement et de sélection. Le travail de recherche présenté ici vise à offrir un premier tour d’horizon des pratiques évaluatives implémentées en biologie au postobligatoire. Il concerne les évaluations sommatives distribuées aux élèves inscrits en Ecole de maturité et en Ecole de culture générale, lors de leur première année de biologie au postobligatoire. Cette analyse tente d’apporter des éléments de réponse quant à l’influence du type de classe, de l’enseignant et du sujet sur la complexité de travaux écrits récoltés auprès des enseignants d’un gymnase du canton de Vaud, ainsi que sur les types de consignes contenus dans leurs énoncés. Au terme de ce travail, il semble être possible d’affirmer que les élèves sont évalués de façon relativement homogène dans les trois types de classes inclus dans l’analyse, tant au niveau de la complexité des tâches évaluatives qui leur sont son proposées que des types de consignes retenus dans les énoncés, du moins en ce qui concerne les enseignants ayant participé à l’étude. En revanche, le sujet évalué semble avoir une incidence non négligeable sur la complexité des questions posées, alors que les types de consigne retenus semblent dépendre fortement du style personnel de l’enseignant qui a rédigé le travail écrit.

description: Buildings generate nearly 40% of global carbon dioxide (CO2) emissions. Embodied carbon accounts for roughly a quarter of that. Innovations in engineered timber products present opportunities for designers to use timber for larger structures now. Such buildings need to be both safe and sustainable. Small- and medium-scale compartment experiments conducted to date have shown that exposed mass timber results in larger external flaming. Empirical correlations, first developed by Law and O’Brien in the 1970s, exist for predicting the characteristics of such flames. The correlation is reproduced in Eurocodes 1 and 3 (to allow designers to calculate heat transfer to external unprotected structure) and BR 187 (to allow external fire spread radiation assessments from external flames to relevant boundaries). However, the correlation does not consider structural fuel load. This paper presents external temperature data from three large-scale (352 m2 floor area) compartment fire experiments; the CodeRed experimental series. External temperature data from CodeRed and two other experimental programmes (RISE and Épernon) is compared with predictions made using the Law and O’Brien correlation. The correlation underpredicts temperature along the flame axis. This paper therefore highlights the need for a modified approach, taking account of the structural fuel load, to enable designers to estimate external flame characteristics from exposed mass timber compartments.
