dairy goat farms: a cross-sectional study. Vet Rec 2019; doi: 10.1136/vr.105346
Die Pseudogravidität gehört zu den wichtigen Fortpflanzungsstörungen der Milchziege. Hierbei kommt es bei
vorliegendem Corpus luteum zu einer Ansammlung aseptischer Flüssigkeit im Uteruslumen ohne Frucht- oder
Plazentaanteile und zu einer Azyklie. Die Menge der intrauterinen Flüssigkeit kann zwischen weniger als 100 ml bis
hin zu mehr als 8 l variieren. Die ätiologisch nicht vollständig geklärte Erkrankung tritt unabhängig von der
Zuchtsaison auf und lässt sich mittels Sonografie diagnostizieren. Ziel dieser Studie war, Daten zu Häufigkeit und
potenziellen Risikofaktoren der Pseudogravidität sowie angewendeten Therapien in der niederländischen
Milchziegenhaltung zu sammeln und auszuwerten.

Abstract
Objective In human medicine, contrary to bovine medicine, close monitoring of risk pregnancies is an integral part
of obstetrics. A prerequisite for this is the knowledge of the normal findings during pregnancy.
Material and methods For this purpose serial transrectal sonographic examination of the placentomes, uterine wall,
and fetal membranes were carried out in 24 healthy (mean age 8.1 ± 3.7 years, Brown Swiss [n = 21], Red Holstein [n =
2], Simmental [n = 1]) cows from week 6 to 43 of gestation. An 8-MHz linear transducer was used to assess the thickness
and appearance of the endometrium and myometrium, the height and width of placentomes, the thickness of the uterine wall
including the adjacent chorion laeve (combined thickness of uterus and placenta, CTUP), and the echogenicity of the
fetal fluids. The uterine wall and the placentomes were measured in 4 different zones of both uterine sides including a
zone near the cervix, at the corpus near to the bifurcation, at the middle, and near the tip of the uterine horn.
Results Placentome height and width were closely correlated with gestational age (height: r = 0.78; width: r =
0.83; both p < 0.0001). Placentome size increased progressively in all uterine zones until week 27, after which time
their growth slowed until week 31 and then plateaued until parturition. Placentomes in the fetus-bearing horn were
larger than in the non-fetus-bearing horn (p < 0.01) and were significantly smaller (height and width) near the tip
of the horn than in the other 3 zones (p < 0.001 to < 0.01). The mean thickness of endometrium and myometrium,
myometrium at the base of the placentome, and the mean CTUP did not change significantly during gestation. The
echogenicity of the allantoic fluid did not change, but the amniotic fluid became more echogenic during gestation (p
< 0.0001).
Conclusion and clinical relevance Sonographic examination of placentomes and amniotic fluid are a promising
diagnostic tool for the estimation of the duration of bovine pregnancies and for diagnosing possible complications.

Authors: Reisdorf Sven 
Published: December 2019

ZusammenfassungMachine Learning stellt insbesondere dann eine sinnvolle Alternative dar, wenn eine Datenanalyse mit wissensbasierten analytischen Methoden sehr aufwendig und schwierig ist. In solchen Fällen bietet sich auch eine Kombination aus analytischen Methoden und empirischen Methoden mittels künstlicher Intelligenz (KI) an. Die Entwicklung verschiedener Auswertefunktionen des Corvis ST ist hierfür ein konkretes Beispiel. In diesem Beitrag wird die Entwicklung dreier Screening-Parameter mittels KI beschrieben. Der Artikel zeigt, wie diese Entwicklungen im Bereich der Erkennung von klinischem und subklinischem Keratokonus sowie Glaukom-Screening klinisch hilfreich sind.

lymphoma masses treated with surgical mass resection (2005–2015). Vet Surg 2019; 48: 1218–1228
Das gastrointestinale Lymphom (GIL) ist die am häufigsten diagnostizierte anatomische Form dieser Neoplasie bei der
Katze. Systemische Chemotherapie stellt derzeit die Standardtherapie beim felinen intermediär- bzw. großzelligen GIL
dar, wobei die Prognose stark variiert und die mediane Überlebenszeit zwischen 3 und 6 Monaten schwankt. Eine
therapeutische chirurgische Intervention wurde bisher nur in Fällen mit lymphombedingter Obstruktion oder
Perforation eingesetzt, die darüber hinausgehende therapeutische Bedeutung der Chirurgie ist derzeit noch unklar.
Ziel der vorliegenden Studie war, den Verlauf von Katzen mit intermediär- bzw. großzelligem GIL nach chirurgischer
Resektion auszuwerten.

Kälbern unter Stallbedingungen. Schweiz Arch Tierheilk 2019; 161 (10): 649–658
Die Thermografie kommt in der Veterinärmedizin in unterschiedlichen Bereichen zum Einsatz, beispielsweise bei der
Euter- und Klauendiagnostik oder der Früherkennung von Infektionskrankheiten. Dieses Diagnostikinstrument unterliegt
internen und externen Einflussfaktoren wie z. B. Stress, bestehenden Erkrankungen bzw. Alter der Tiere (intern) oder
Umweltfaktoren wie Haltungsbedingungen, Belüftung und Umgebungstemperatur (extern). Da Fellverschmutzungen an der
Messstelle die Ergebnisse verfälschen können, bieten sich haarlose Körperregionen wie Flotzmaul oder Mundschleimhaut
an. Bei Messungen in anderen Regionen sollte der Bereich zuvor geschoren werden, um diesen Einflussfaktor zu
minimieren. Ziel der Studie war, Einflussfaktoren auf die Thermografie an verschiedenen Körperregionen beim Kalb zu
erfassen, um dieses potenzielle Diagnostikum im Bereich Kälbergesundheit zu validieren.

Beim Sehnenstelzfuß (SSF), auch als Neuromyodysplasia congenita oder „congenital articular rigidity“ bezeichnet,
handelt es sich um eine unphysiologische Beugung der Gliedmaßengelenke aufgrund einer Muskelkontraktur der
Zehenbeuger. Diese Muskelkontraktur tritt in unterschiedlichen Schweregraden (Grad 1–3) auf und vermittelt dabei
eine scheinbare Verkürzung der Beugesehnen an der betroffenen Gliedmaße. Die weltweit vorkommende Erkrankung besteht
meist von Geburt an. Erworbene Formen kommen als Komplikation anderer Grunderkrankungen mit verlängerten
Liegephasen, in Verbindung mit Mangelzuständen (Mangan, Selen) oder nach intrauterinen Virusinfektionen vor. Die
Ursache des kongenitalen SSF ist nicht genau geklärt, eine genetische Komponente wird vermutet.

Abstract
Objective Postpartum hemorrhage (PPH) is the most common cause of maternal mortality and morbidity worldwide, most of which occurs in resource-poor settings. Placement of a uterine balloon may be life-saving in uncontrolled PPH. The Every Second Matters for Mothers-Uterine Balloon Tamponade (ESM-UBT) device is an ultra-low-cost uterine balloon designed for global access. The purpose of this study was to evaluate the mechanical properties of the ESM-UBT device.
Study design Intraluminal pressures, diameters, and burst volumes of condom uterine balloons and Foley catheter balloons of ESM-UBT devices were measured in open air and inside uterus models. Condom uterine balloons were tested with uterus model sizes of 100, 250, and 500mL. The condom-catheter O-ring attachment tensile strength was also evaluated.
Results All 28 samples of ESM-UBT condom uterine balloons maintained their integrity for at least 3 hours when subjected to pressures of 200 mm Hg or greater across each of the tested uterine volumes. No Foley catheter balloons burst after instillation of 30mL, O-rings withstood forces of 15.4 ± 2.1 N, and condom uterine balloons stretched to 35.8 ± 2.1 cm without loss of integrity.
Conclusion The mechanical properties of the ESM-UBT device make it attractive for scale across resource-poor settings.

Role of Biomarkers in Guiding Cure of Viral Hepatitis B
Authors: Buti Maria , Riveiro-Barciela Mar , Rodríguez-Frías Francisco , Tabernero David , Esteban Rafael 
Published: December 2019

AbstractChronic hepatitis B (CHB) virus infection is a global public health threat affecting approximately 257 million individuals worldwide. Hepatitis B surface antigen (HBsAg) loss has been the classic endpoint to define functional cure and decrease the large pool of individuals with CHB. Current treatments with nucleos(t)ide analogues persistently suppress hepatitis B virus (HBV) deoxyribonucleic acid in most CHB patients, but rarely achieve functional cure. New viral biomarkers, such as quantitative HBsAg, hepatitis B core-related antigen, and HBV ribonucleic acid, and combinations of these markers have the potential role of guiding HBV cure by enabling selection of the best candidates for therapy, identifying individuals with a higher likelihood of achieving HBsAg loss, and helping in the design of studies with new drugs. However, some of the assays used to analyze these markers require standardization and improvements in the level of detection. Analysis of host biomarkers to assess the host immune response to HBV is also important, as the natural course of CHB is determined by the interplay between viral replication and the immune response. These biomarkers are, however, in an early phase of development.
Linking insect pest models with climate change scenarios to project against future risks of agricultural insect pests.

Published: December 2019

Abstract
The linking of climate projections and insect pest models is an important step for determining effective management and counter-measures. There is an urgent need to link pest models and climate change projections for a better understanding of the outcomes of climate change-inflicted variations in future pest status. The present review aims to summarize the insect pest models that have been linked with global circulation model-based climate change scenarios and also provide a reference for future risk evaluation of agriculturally and horticulturally important insect pests. Further, discussions are also included on linking of climatic pattern matching function and process-based climatic response-type models with climate change scenarios for understanding the impact of model selection on pest status. Most simulation models use projected temperature as the main driver to run for pest risk. A total of 29 climatic pattern matching and 19 phenology-based simulation studies for insect pest risk, mainly available from USA, China, Australia, India, New Zealand and Slovenia, met the criterion of linking pest models with climate change projections. Most of the studies considered only one or few GCM-based climate change projections. No study has been simulated with an option of management components. The present review suggests that insect pest modelling for future pest risk should include more GCMs with several climatic factors by also considering the cropping systems of a particular area.

The key comparison CCQM-K137 was aimed at evaluating the level of compatibility of laboratories' preparative capabilities for gravimetric nitrogen monoxide/nitrogen primary reference mixtures at mole fractions of 30 μmol mol-1 and 70 μmol mol-1.
The comparison was organised by the BIPM. It consisted in the simultaneous comparison of a suite of 2n primary gas standards, two standards to be prepared by each of the n participating laboratories at the nominal values of 30 μmol mol-1 and 70 μmol mol-1. Two independent analytical methods were used by the BIPM to analyse the amount fraction of nitrogen monoxide (NO) in nitrogen; UV spectrophotometry and chemiluminescence (CLD). The agreement between the results obtained with the two main techniques served to highlight possible issues in the preparation of the standards. During this comparison, standards prepared by two participants appeared to result in a larger bias between the analysers than observed for others. These observations were explained by the analysis of all standards by Fourier Transform Infrared Spectroscopy (FTIR) which identified the presence of a larger amounts of water vapour (H2O), nitrous oxide (N2O) and nitrogen dioxide (NO2) in these standards, which are the three main impurities which can appear in mixtures of NO in nitrogen.
The above observations were used to underpin the selection of standards (at each nominal NO mole fraction) which can be considered as a consistent set, allowing the calculation of a calibration line by a Generalised Least-Square regression. Key Comparison Reference Values were then proposed for all participants as predicted values from the calibration lines. Interferences caused in the response of the CLD analyser by impurities (verified by FTIR measurements) led to only the results from the UV analyser being proposed for the KCRV and Degrees of Equivalence calculations. Good agreement was observed between all participants who could prepare their standards with minimum levels of impurities.
The key comparison CCQM-K137 is considered to present an analytical challenge at both nominal mole fractions and therefore considered as a Specialised (Track C) comparison in the CCQM nomenclature.

Abstract
There is little information on the radiation dose levels of returnees to areas once designated as legal no-go zones, after evacuation orders were lifted subsequent to the 2011 Fukushima Daiichi nuclear power plant incident. This study used individual radiation dosimeter monitoring and a location history survey to conduct the most recent dose assessment of external exposure among returnees to former no-go zones. We specifically determined correlation and agreement between external doses and the air dose rate in residential areas and quantified both uncertainty and population variability of the observed data using Monte Carlo (MC) simulation methods. A total of 239 voluntary participants across ten municipalities were analysed; their representativeness of all affected municipal populations was confirmed in terms of air dose rate distribution in residential areas. We found that individual doses were statistically significantly correlated with the air dose rate based on government airborne monitoring. This implies that airborne monitoring can provide sufficient information for understanding dose levels among such returnees. The MC simulations demonstrated that the mean of the annual dose in 2019 (including natural background doses) was 0.93 (95% uncertainty interval 0.53–1.76) mSv, with limited variation between municipalities. As of 2019, this implies that doses from external exposure were very low among returnees and would be associated with a very low likelihood of physical effects according to current scientific consensus. However, these results should be taken with caution due to several study limitations, including selection and participation biases. Regardless, its findings will enhance societal debates about how both individual-dose and government airborne monitoring practices should operate in the future and how the government can improve the public outlook for radiation doses in incident-affected areas.

Abstract
The steel target evaporation and the gas-dynamic processes were calculated, thenfollowed by the plasma creation on in the metal vapor under the influence of nanosecond pulses were calculated. Mathematical model based on the Euler equations for the inviscid gas flow in conjunction statement with the radiation transfer equation in the diffusion multi-group approximation and the heat equation in solid metal was formulated. Nonlinear evaporation, depending on the energy entering to the target surface, was calculated using analytical expressions for the Knudsen layer. The structures of gas-dynamic flows with the formation of shock waves in an ambient gas (air) in the active vaporization mode and during plasma formation are were studied, also the thermal state of the target is was determined in the one-dimensional formulation. The comparison of the efficiency of energy transfer to the target is was made in both cases, : from laser radiation directly and when plasma appearsappeared, by means of thermal radiation. The significant increase in the adsorption coefficient of energy in the case of the appearance of plasma is shown.
Deformation and acceleration-induced fragmentation of the liquid drops in the gradient air flow
Authors: Boiko V M , Poplavski S V , Pivovarov A A , Samsonova I V 
Published: December 2019

Abstract
The regimes of aerodynamic destruction of a falling drop of a low-viscosity liquid in a falling accelerating air flow were experimentally studied. This model formulation allows us to study the behaviour of a drop when the direction of the aerodynamic force is reversed. The experiments showed a large deformation and rather high instantaneous drop acceleration at a moderate velocity gradient. The results confirmed that a change in the sign of aerodynamic force increases the effect of Rayleigh-Taylor instability.

Authors: Klinkov S V , Kosarev V F , Shikalov V S 
Published: December 2019

Abstract
The paper presents the results of investigation of dependence of substrate temperature upon nozzle traverse velocity under cold spray conditions. A model is proposed for prediction of substrate temperature. Experimental and simulated data were obtained in the typical range of change in the nozzle traverse speed (1-400 mm/s) and air stagnation temperatures (200-600°C), encountered in the practice of cold spraying. The simulated data are in good agreement with experimental. An approximate analytical equation is proposed for estimation of substrate temperature during cold spraying in a wide range of gas stagnation temperatures and nozzle traverse velocities.

Published: December 2019

Abstract
The three-dimensional transient problem of the interaction of artificial space debris particles (steel bolt M12) with a spacecraft model reactor is solved. Two cases of interaction are considered, the first is the reactor filled with water, and the second is the empty reactor. The calculations show that the impact of a high-speed steel bolt on the reactor with water at a speed of 11.17 m/s leads to the reactor failure. A water-free reactor obtains catastrophic damage to the hull shell and fuel cells.
