Intrinsic limitations of load‐shifting response dynamics: preliminary results from particle hopping models of homogeneous density incompressible loads
Authors: Carvalho Pedro M.S. , Ferreira Luís A.F.M.
Published: February 2019

In this study, end‐use storage loads with elasticity constrained by a time window are modelled by a particle hopping cellular automaton. The automaton model is introduced and parameterised to obtain results on the ideal load‐shifting response. Simulation is used to analyse the intrinsic limitations of load‐shifting ramping capabilities. New concepts are introduced: load particle velocity and particle density. These concepts are used to advance formal hypotheses on the ramping limitations. Hypotheses are tested against experimental results to conclude about the underlying potential of load‐shifting demand response.
Carbonaceous nano-dust emission in proto-planetary discs: the aliphatic-aromatic components
Authors: Boutéraon T. , Habart E. , Ysard N. , Jones A. P. , Dartois E. , Pino T.
Published: February 2019

Context. In the interstellar medium, carbon (nano-)grains are a major component of interstellar dust. This solid phase is more vulnerable to processing and destruction than its silicate counterpart. It exhibits a complex, size-dependent evolution that is due to interactions within different radiative and dynamical environments. Infrared signatures of these carbon nano-grains are seen in a large number of discs around Herbig HAeBe stars.

Aims. We probe the composition and evolution of carbon nano-grains at the surface of (pre-)transitional proto-planetary discs around Herbig stars.

Methods. We present spatially resolved infrared emission spectra obtained with the Nasmyth Adaptive Optics System (NAOS) Near-Infrared Imager and Spectrograph (CONICA) at the Very Large Telescope (VLT) in the 3–4 μm range with a spatial resolution of 0.1′′, which allowed us to trace aromatic, olefinic, and aliphatic bands that are attributed to sub-nanometer hydrocarbon grains. We applied a Gaussian fitting to analyse the observed spectral signatures. Finally, we propose an interpretation in the framework of the The Heterogeneous dust Evolution Model of Interstellar Solids (THEMIS).

Results. We show the presence of several spatially extended spectral features that are related to aromatic and aliphatic hydrocarbon material in discs around Herbig stars, from ~10 to 50–100 au, and even in inner gaps that are devoid of large grains. The correlation and constant intensity ratios between aliphatic and aromatic CH stretching bands suggests a common nature of the carriers. Given their expected high destruction rates through UV photons, our observations suggest that they are continuously replenished at the disc surfaces.
WeanNet: Das Netzwerk pneumologischer Weaningzentren
Authors: Schönhofer B.
Published: February 2019

Die invasive Beatmung mit dem endotrachealen Tubus als Beatmungszugang ist Therapie der Wahl der akuten respiratorischen Insuffizienz. Multifaktoriell bedingt steigt die Zahl der Patienten, die länger dauernd vom Beatmungsgerät abhängig sind. Die prolongierte Entwöhnung von der mechanischen Beatmung (engl. „Weaning“ oder „Liberation“) hat daher eine zunehmende Bedeutung.

Seit den 90er-Jahren des vergangenen Jahrhunderts wurden in pneumologischen Kliniken Weaningeinheiten etabliert. Mit dem Ziel, in diesen Weaningzentren eine möglichst hohe Behandlungsqualität zu erreichen, wurde im Jahr 2007 innerhalb der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin (DGP) das Netzwerk „WeanNet“ gegründet. Die Struktur-, Prozess- und Ergebnisqualität der Weaningzentren wird im Rahmen eines Zertifizierungsverfahrens überprüft. Bis zum Stand Oktober 2018 wurden 53 Weaningzentren zertifiziert.

Wichtige Aussagen und Empfehlungen zu Behandlungsstrategien im prolongierten Weaning wurden im Jahr 2014 in der S2k-Leitlinie „Prolongiertes Weaning“ unter Federführung der DGP erstellt.

Erstmals wurden 2016 von der WeanNet-Study Group Daten zum Outcome von 6899 Patienten mit prolongiertem Weaning aus dem WeanNet-Register veröffentlicht. Die Mehrzahl der Patienten (62 %) konnte erfolgreich vom Respirator entwöhnt werden. Eine nicht invasive Beatmung nach prolongiertem Weaning war in ca. 19 % der Patienten aufgrund einer chronisch ventilatorischen Insuffizienz erforderlich.

Wegen zunehmender Patientenzahl und damit verbundenen Herausforderungen im Bereich der intra- und extrahospitalen Beatmungsmedizin steht „WeanNet“ dem Gesundheitswesen als zukunftsorientierter Gesprächspartner zur Verfügung.
The treatment of migraine patients with triptans – is there a need for further Rx-to-OTC switches?
Authors: Schneider-Ziebe Anissa , May Uwe
Published: February 2019

Objective The disease migraine affects a large share of the German population and is linked to a high economic potential in terms of direct and indirect sickness costs. Triptans are the recommended treatment in the case of an acute migraine attack. Both, the disease and its appropriate treatment are of interest in the context of self-medication and Rx-to-OTC switch efforts. Therefore, a survey was carried out with the intention to collect data among migraine patients regarding the use of analgesics in general and of triptans specifically. This data can be the basis for further health economic considerations.

Methods By an online survey among 206 migraine patients, different data regarding patients suffering from migraine, the frequency and sort of symptoms and the use of analgesics in general as well as triptans specifically was collected and analysed. A special focus was on symptoms affecting patients’ productivity, their use of triptans and their satisfaction with the current supply situation with triptans.

Results The survey revealed among other findings that most patients suffer from symptoms which limit their productivity or their ability to work and make an immediate treatment necessary. Most patients know well about their disease and feel able to treat themselves in the context of self-medication once they are diagnosed by a physician. In this context a demand for further triptans available without a prescription could be identified. This is specifically, because patients respond differently to various triptans. Therefore, a larger variety of prescription free triptans would increase the number of patients with access to OTC triptans significantly.

Conclusion Most survey respondents know well about their disease and the appropriate treatment and feel able to treat themselves within the scope of self-medication. Nevertheless, they mostly respond to one triptan only. In the case of an acute migraine attack an immediate treatment is required, ideal is an intake of triptans as soon as first symptoms occur. In this context pharmacies play an important role as fast and low-threshold access point to medications. Because only a limited number of patients responds to the already prescription free available triptans, there is a demand for further Rx-to-OTC switches of triptans among migraine patients which should be considered in further switch efforts in Germany.
Digital Analysis of Nasal Airflow Facilitating Decision Support in Rhinosurgery
Authors: Brüning Jan , Lamecker Hans , Zachow Stefan , Heppt Werner , Schmidt Nora , Goubergrits Leonid , Hildebrandt Thomas
Published: February 2019

Successful functional surgery on the nasal framework requires reliable and comprehensive diagnosis. In this regard, the authors introduce a new methodology: Digital Analysis of Nasal Airflow (diANA). It is based on computational fluid dynamics, a statistical shape model of the healthy nasal cavity and rhinologic expertise. diANA necessitates an anonymized tomographic dataset of the paranasal sinuses including the complete nasal cavity and, when available, clinical information. The principle of diANA is to compare the morphology and the respective airflow of an individual nose with those of a reference. This enables morphometric aberrations and consecutive flow field anomalies to localize and quantify within a patient’s nasal cavity. Finally, an elaborated expert opinion with instructive visualizations is provided. Using diANA might support surgeons in decision-making, avoiding unnecessary surgery, gaining more precision, and target-orientation for indicated operations.
The Healthy Nasal Cavity—Characteristics of Morphology and Related Airflow Based on a Statistical Shape Model Viewed from a Surgeon's Perspective
Authors: Hildebrandt Thomas , Schmidt Nora , Lamecker Hans , Heppt Werner , Zachow Stefan , Goubergrits Leonid , Brüning Jan
Published: February 2019

Functional surgery on the nasal framework requires referential criteria to objectively assess nasal breathing for indication and follow-up. This motivated us to generate a mean geometry of the nasal cavity based on a statistical shape model. In this study, the authors could demonstrate that the introduced nasal cavity's mean geometry features characteristics of the inner shape and airflow, which are commonly observed in symptom-free subjects. Therefore, the mean geometry might serve as a reference-like model when one considers qualitative aspects. However, to facilitate quantitative considerations and statistical inference, further research is necessary. Additionally, the authors were able to obtain details about the importance of the isthmus nasi and the inferior turbinate for the intranasal airstream.

Objective To describe physician perceptions of the potential goals, characteristics, and content of the electronic problem list (PL) in pediatric trauma.

Methods We conducted 12 semistructured interviews with physicians involved in the pediatric trauma care process, including residents, fellows, and attendings from four services: emergency medicine, surgery, anesthesia, and pediatric critical care. Using qualitative content analysis, we identified PL goals, characteristics, and patient-related information from these interviews and the hospital's PL etiquette document of guideline.

Results We identified five goals of the PL (to document the patient's problems, to make sense of the patient's problems, to make decisions about the care plan, to know who is involved in the patient's care, and to communicate with others), seven characteristics of the PL (completeness, efficiency, accessibility, multiple users, organized, created before arrival, and representing uncertainty), and 22 patient-related information elements (e.g., injuries, vitals). Physicians' suggested criteria for a PL varied across services with respect to goals, characteristics, and patient-related information.

Conclusion Physicians involved in pediatric trauma care described the electronic PL as ideally more than a list of a patient's medical diagnoses and injuries. The information elements mentioned are typically found in other parts of the patient's electronic record besides the PL, such as past medical history and labs. Future work is needed to evaluate the optimal design of the PL so that users with emergent cases, such as pediatric trauma, have access to key information related to the patient's immediate problems.

Authors: Tasman Abel-Jan
Published: February 2019

The reconstruction of the nasal dorsum after a hump resection is challenging if narrowing of the nose is to be avoided, the nasal skin is very thin, and the nasal bones are short. This report describes the replacement of the bony and cartilaginous nasal dorsum after resection with an anatomically shaped dorsal replacement graft of diced cartilage in fibrin glue. The technique is illustrated with a clinical case and sonographic morphometry of the nasal dorsum and tip. A modification of the diced cartilage glue graft for thin-skinned patients is presented.
Dexmedetomidine to Treat 3, 4-Methylenedioxymethamphetamine-Induced Agitation in a 13-Month-Old Infant: A Case Report and Literature Review
Authors: Sanders Patricia J. L. T. , Hanot Jan
Published: February 2019

We report a 13-month-old infant who accidentally ingested a tablet of 3, 4-methylenedioxymethamphetamine (MDMA) and was brought to the emergency department with tachycardia, seizures, mydriasis, and altered mental status. The patient received multiple doses of benzodiazepines to treat the seizures and developed respiratory insufficiency needing intubation. After extubation, the patient developed hyperactivity, myoclonic, and choreoathetoid movements which were unresponsive to benzodiazepines. Dexmedetomidine was started with good response. The patient made a full clinical recovery. This is the first case that illustrates the possibility to treat MDMA-induced agitation with dexmedetomidine in a 13-month-old infant.
Homozygous Deletion of the CFTR Gene Caused by Interstitial Maternal Isodisomy in a Peruvian Child with Cystic Fibrosis
Authors: Vásquez Sotomayor Flor , Abarca-Barriga Hugo Hernán
Published: February 2019

We report the first case in Peru of cystic fibrosis caused by a homozygous deletion of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. A 10-month-old child who presented with meconium ileus and pancreatic insufficiency was tested for cystic fibrosis. Both parents of the child are of Peruvian background, are nonconsanguineous, and have no personal or family history of the disease. Chromosome microarray analysis revealed a homozygous deletion of the CFTR gene on chromosome 7 (7q31.2) within a maternally derived 12.8-Mb region of loss of heterozygosity with deletion of a region that includes the CFTR gene. Parental testing confirmed this finding. This case highlights the great importance of molecular testing and the study of chromosomal rearrangements in reaching a correct diagnosis and providing proper genetic counseling to the affected families.

Published: February 2019

We present a superconducting micro-resonator array fabrication method that is scalable and reconfigurable and has been optimized for high multiplexing factors. The method uses uniformly sized tiles patterned on stepper photolithography reticles as the building blocks of an array. We demonstrate this technique on a 101-element microwave kinetic inductance detector (MKID) array made from a titanium-nitride superconducting film. Characterization reveals 1.5% maximum fractional frequency spacing deviations caused primarily by material parameters that vary smoothly across the wafer. However, local deviations exhibit a Gaussian distribution in fractional frequency spacing with a standard deviation of 2.7 × 10−3. We exploit this finding to increase the yield of the BLAST-TNG 250 μm production wafer by placing resonators in the array close in both physical and frequency space. This array consists of 1836 polarization-sensitive MKIDs wired in three multiplexing groups. We present the array design and show that the achieved yield is consistent with our model of frequency collisions and is comparable to what has been achieved in other low temperature detector technologies.
A high pressure cell using metallic windows to investigate the structure of molecular solutions up to 600 MPa by small-angle neutron scattering
Authors: Annighöfer Burkhard , Hélary Arnaud , Brûlet Annie , Colas de la Noue Alexandre , Loupiac Camille , Combet Sophie
Published: February 2019

We report on a high pressure (HP) cell designed for the determination of the structure of molecular solutions by small-angle neutron scattering (SANS). The HP cell is fitted up with two thick metallic windows that make the device very resistant under hydrostatic pressures up to 600 MPa (or 6 kbar). The metallic windows are removable, offering the possibility to adapt the HP cell to a given study with the pressure desired on an appropriate spatial range to study the structure of various molecular solutions by SANS. In this context, we report the absorption, transmission, and scattering properties of different metallic windows. Finally, we describe, as a proof of principle, the solution structure changes of myoglobin, a small globular protein.

Published: February 2019

In this work, structural, magnetic, and local properties of GdIn(NixCu1−x)4 (0.00 ≤ x ≤ 1.00) samples synthesized via the flux method are investigated by means of X-ray, magnetization, specific heat, and electron spin resonance measurements. The analysis of X-ray powder diffraction data taken at room temperature reveals that all samples belong to the cubic space group (Cl5b-type structure) with lattice parameters, a, ranging from 7.08 < a < 7.23 Å. Interestingly, the analysis of both T-dependence magnetic susceptibility and MvsH loops indicates a gradual transition from antiferromagnetic to ferromagnetic ground states as a function of the Ni-doping. The transition temperatures are confirmed via specific heat measurements. Finally, electron spin resonance data taken in the temperature range of 100 ≤ T ≤ 300 K show a single Dysonian line shape, which is characteristic of a metallic environment. A nearly T-independent g-value was observed and the value was concentration independent. Besides, the doped samples show an increase of the residual linewidth, which can be linked with the chemical disorder introduced by the Ni-doping. Our results are discussed considering the bottleneck and multiple band effects on the Gd3+ spin dynamics in this series and their implication in the magnetic frustration observed in these materials.
Operators in quantum machine learning: Response properties in chemical space
Authors: Christensen Anders S. , Faber Felix A. , von Lilienfeld O. Anatole
Published: February 2019

The role of response operators is well established in quantum mechanics. We investigate their use for universal quantum machine learning models of response properties in molecules. After introducing a theoretical basis, we present and discuss numerical evidence based on measuring the potential energy’s response with respect to atomic displacement and to electric fields. Prediction errors for corresponding properties, atomic forces, and dipole moments improve in a systematic fashion with training set size and reach high accuracy for small training sets. Prediction of normal modes and infrared-spectra of some small molecules demonstrates the usefulness of this approach for chemistry.

Published: February 2019

Hydrogenated diamond MOSFETs with self-oxidized alumina as a gate dielectric are fabricated. The diamond MOSFETs show a high maximum drain current density of 466 mA/mm at VGS = −6 V, a transconductance of 58 mS/mm, and an off-state breakdown voltage of −53 V. The maximum output power density reaches 745 mW/mm at 2 GHz continuous wave, which is the highest reported value for diamond transistors measured at 2 GHz. The output power value measured is lower than that estimated. Pulse I-V analysis shows that the main factor that affects the output power of the diamond MOSFETs is the traps in the channel.
Phase separation of a ternary lipid vesicle including n-alkane: Rugged vesicle and bilayer flakes formed by separation between highly rigid and flexible domains
Authors: Hishida Mafumi , Yanagisawa Ryuta , Yamamura Yasuhisa , Saito Kazuya
Published: February 2019

We investigate the phase separation of a ternary lipid bilayer including n-alkane and construct the ternary phase diagram. When a certain proportion of a long n-alkane is mixed with a binary mixture of lipids, which exhibit the disordered liquid-crystalline phase and the ordered gel phase at room temperature, we observed the characteristic morphology of bilayers with phase separation. The ordered bilayer forms flat and rigid domains, which is connected or rimmed with flexible domains in the disordered phase. The asymmetric emergence of the phase separation region close to the ordered phase side is interpreted based on the almost equal distribution of the n-alkane to the ordered and disordered phase domains.
High-sensitivity plasma density retrieval in a common-path second-harmonic interferometer through simultaneous group and phase velocity measurement
Authors: van Tilborg J. , Gonsalves A. J. , Esarey E. , Schroeder C. B. , Leemans W. P.
Published: February 2019

Precise measurements of the plasma density in ionized gas cells and discharged capillaries are critical to the design and operation of plasma-based accelerators, active plasma lenses, and plasma-based radiation sources. In this manuscript, a spectral-domain common-path second-harmonic interferometer is upgraded with the simultaneous measurement of the group and phase velocity, allowing for high-sensitivity density characterization (from the phase velocity advance) without the need for phase tracking from zero-density (enabled by the group velocity delay). The technique is applied to 1.5-cm-long plasma structures, without density ambiguity in parameter scans with >2π phase jumps. The single-shot sensitivity in phase retrieval is demonstrated at 63 mrad, equivalent to a density-length product of 1.8·1015 cm−2. This is an improvement of ×45 compared to group velocity analysis alone.
Validation of a three-dimensional depth-semi-averaged model
Authors: Antuono M. , Valenza S. , Lugni C. , Colicchio G.
Published: February 2019

The present work completes the validation of the depth-semi-averaged model defined in Antuono et al. [“A depth semi-averaged model for coastal dynamics,” Phys. Fluids 29, 056603 (2017)] providing a numerical implementation in three spatial dimensions. In particular, the model is aimed at describing a wide variety of phenomena typical of the coastal region, as for example nonlinear interaction between waves and the bottom bathymetry (diffraction/refraction phenomena), dispersion effects, and beach inundation. To this purpose, the proposed scheme is tested against benchmark experimental data available in the literature for wave propagation problems in both intermediate and shallow water conditions. A final simulation is carried out by considering a tsunami wave running over a prototype bathymetry resembling a bay-promontory coastline. Different widths of the bay have been considered, describing their influence on the run-up dynamics.
Computing collision stress in assemblies of active spherocylinders: Applications of a fast and generic geometric method
Authors: Yan Wen , Zhang Huan , Shelley Michael J.
Published: February 2019

In this work, we provide a solution to the problem of computing collision stress in particle-tracking simulations. First, a formulation for the collision stress between particles is derived as an extension of the virial stress formula to general-shaped particles with uniform or non-uniform mass density. Second, we describe a collision-resolution algorithm based on geometric constraint minimization which eliminates the stiff pairwise potentials in traditional methods. The method is validated with a comparison to the equation of state of Brownian spherocylinders. Then we demonstrate the application of this method in several emerging problems of soft active matter.
Bidirectional spin filter in a triple orbital molecule junction by tuning the magnetic field along a single direction
Authors: Xiong Yong-Chen , Luo Shi-Jun , Zhou Wang-Huai , Li Wei , Zhang Chuan-Kun
Published: February 2019

Metal-molecule-metal junction is considered the basing block and key element of molecular spintronic devices, within which to generate spin polarized currents is one of the most fundamental issues for quantum computation and quantum information. In this paper, by employing a parallel triple orbital molecule junction with large inter-orbital tunneling couplings, we propose theoretically a bidirectional spin filter where both spin-up and spin-down currents could be obtained by simply adjusting the external magnetic field to different regimes along a single direction, and the filtered efficiencies could reach almost 100%. The Zeeman effect and the occupancy switching for the bonding and anti-bonding states are found to be responsible for the spin selective transport. We demonstrate that our scheme is robust for large parameter spaces of the orbital energy level, except the particle-hole symmetric point, and is widely suitable for the strong-, weak-, and non-interacting cases. To implement these problems, we use the Wilson’s numerical renormalization group technique to treat such systems.
Quantum dynamics and spectroscopy of dihalogens in solid matrices. II. Theoretical aspects and G-MCTDH simulations of time-resolved coherent Raman spectra of Schrödinger cat states of the embedded I2Kr18 cluster
Authors: Picconi David , Cina Jeffrey A. , Burghardt Irene
Published: February 2019

This study presents quantum dynamical simulations, using the Gaussian-based multiconfigurational time-dependent Hartree (G-MCTDH) method, of time-resolved coherent Raman four-wave-mixing spectroscopic experiments for the iodine molecule embedded in a cryogenic crystal krypton matrix [D. Picconi et al., J. Chem. Phys. 150, 064111 (2019)]. These experiments monitor the time-evolving vibrational coherence between two wave packets created in a quantum superposition (i.e., a “Schrödinger cat state”) by a pair of pump pulses which induce electronic B Πu30+⟵XΣg+1 transitions. A theoretical description of the spectroscopic measurement is developed, which elucidates the connection between the nonlinear signals and the wave packet coherence. The analysis provides an effective means to simulate the spectra for several different optical conditions with a minimum number of quantum dynamical propagations. The G-MCTDH method is used to calculate and interpret the time-resolved coherent Raman spectra of two selected initial superpositions for a I2Kr18 cluster embedded in a frozen Kr cage. The time- and frequency-dependent signals carry information about the molecular mechanisms of dissipation and decoherence, which involve vibrational energy transfer to the stretching mode of the four “belt” Kr atoms. The details of these processes and the number of active solvent modes depend in a non-trivial way on the specific initial superposition.
Stability of CHIKV infection models with CHIKV-monocyte and infected-monocyte saturated incidences

Published: February 2019

We study the global stability of within-host Chikungunya virus (CHIKV) infection models with antibodies. We incorporate two modes of infections, attaching a CHIKV to a host monocyte, and contacting an infected monocyte with an uninfected monocyte. The CHIKV-monocyte and infected-monocyte incidence rates are given by saturation. In the second model we consider two classes of infected monocytes, latently infected monocytes and actively infected monocytes. The global stability analysis of the equilibria are established using Lyapunov method. We support our theoretical results by numerical simulations.

To reduce the manufacturing cost of liquid crystal (LC) panels, we examine the potential of an ion-beam-treated indium tin oxide (ITO) film as an LC alignment layer as well as a transparent electrode. In this study, thus, an ITO film in an LC panel is developed to serve as an LC alignment layer as well as an electrode. To determine if they can be utilized for liquid crystal display (LCD) applications, we investigate the anchoring strength of ITO alignment layers according to ion beam conditions through the roll pattern in electroconvection of LCs. In the optimized ion beam condition of our experiment, the azimuthal surface anchoring strength of the ITO alignment layer is approximately 3.1 × 10−6 N/m, which corresponds to that of polyvinyl alcohol (PVA) and is ten times higher than that of rubbed ITO alignment layers. To further enhance the anchoring strength of the ITO film by the synergistic effect of alignment methods (rubbing + ion beam treatment), we perform ion beam treatment after rubbing on the ITO film, after which the azimuthal surface anchoring strength of the ITO alignment layer is approximately 1.7 × 10−5 N/m, which is four times higher than that of rubbed PVA, thus achieving an appropriate value for LCD applications. As a result of the electro-optical characteristics of twisted nematic LC cells with rubbed and ion-beam-treated ITO alignment layers, we obtained good dark and bright states as verified by the voltage vs. transmittance curves.
Wildlife on Farms

Published: February 2019

Many landowners are interested in the native animals that live on their farms or once occurred there. In particular they want to know why particular species are present (or absent), what they can do to encourage them to visit, and what they might do to keep them there.
Wildlife on Farms outlines the key features of animal habitats—large flowering trees, hollow trees, ground cover, understorey vegetation, dams and watercourses—and describes why landholders should conserve these habitats to encourage wildlife on their farms. It shows how wildlife conservation can be integrated with farm management and the benefits this can bring.
The book presents 29 example species—mammals, birds, reptiles and amphibians—that are common to a large part of southern and eastern Australia. Each entry gives the distinguishing features of the animal, key features of its required habitat, and what can be done on a farm to better conserve the species.
Predators with Pouches
Authors: Jones Menna , Dickman Chris , Archer Mike
Published: February 2019

Predators with Pouches provides a unique synthesis of current knowledge of the world’s carnivorous marsupials—from Patagonia to New Guinea and North America to Tasmania. Written by 63 experts in each field, the book covers a comprehensive range of disciplines including evolution and systematics, reproductive biology, physiology, ecology, behaviour and conservation.
Predators with Pouches reveals the relationships between the American didelphids and the Australian dasyurids, and explores the role of the marsupial fauna in the mammal community. It introduces the geologically oldest marsupials, from the Americas, and examines the fall from former diversity of the larger marsupial carnivores and their convergent evolution with placental forms.
The book covers all aspects of carnivorous marsupials, including interesting features of life history, their unique reproduction, the physiological basis for early senescence in semelparous dasyurids, sex ratio variation and juvenile dispersal. It looks at gradients in nutrition—from omnivory to insectivory to carnivory—as well as distributional ecology, social structure and conservation dilemmas.
Soil Physical Measurement and Interpretation for Land Evaluation
Authors: McKenzie Neil , Coughlan Keppel , Cresswell Hamish
Published: February 2019

Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides:

practical guidelines on the soil physical measurements across a range of soils, climates and land uses;
straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and
guidelines on the interpretation of results and integration with land resource assessment.

Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.
Landscape and Building Design for Bushfire Areas
Authors: Ramsay Caird , Rudolph Lisle
Published: February 2019

Shortlisted in TAFE Vocational Education category in the 2004 Australian Awards for Excellence in Educational Publishing.
The devastation wreaked by bushfires on Australian homes and landscapes is an all too familiar scenario. Yet, why do we often see one house burn, whilst an apparently similar house on an adjacent block can endure? Research has shown that many factors affect the chances of a building surviving a bushfire. If you are designing landscapes and buildings in bushfire areas you need to be aware of these factors so that the chances of losses to life and property can be minimised.
Landscape & Building Design for Bushfire Areas integrates the latest scientific knowledge about buildings and bushfires with a flexible design approach.
The book contains two main sections:
1) Provides a clear description of what happens in a bushfire. It describes the environment in which bushfires occur, how a fire attacks, and how buildings are ignited and destroyed.
2) Sets out a practical design approach to the design of buildings and their immediate surroundings. It presents a range of options for designing the various elements of both landscapes and buildings in bushfire-prone areas.
This book encourages design for bushfire to be included as a normal part of designing in bushfire-prone areas, rather than as an undesirable add-on. It will assist planning and building regulatory authorities to improve and administer regulatory requirements and guidelines.
