Published: July 2021

AbstractBasilar skull fractures in horses can occur at any age, although young horses are particularly prone to this type of injury. This manuscript describes two foals with a basisphenoid bone fracture, with clinical presentations ranging from mild neurological signs up to severe neurological compromise. The absence of neurological signs does not exclude a fracture of this bone, as lethargy and retropharyngeal swelling may be the only clinical signs. Radiography can help define skeletal trauma involving the basilar region of the head, but superimposition of complex skull anatomy limits its use. Endoscopy of the guttural pouches region can be also helpful, but it does not provide enough evidence for a diagnosis. Thus, computed tomography is the optimal imaging technique for a rapid and straightforward diagnosis, as it is superior to radiography defining the type of fracture and the location of the fragments as well as the soft tissue involvement.
Medial patellar luxation in a chondrodysplastic Alaskan Malamute
Authors: Chong Wye Li , Michelsen Jacob 
Published: July 2021

AbstractA 14‐month‐old Alaskan Malamute with chondrodysplasia (dwarfism) presented for progressive bilateral hindlimb lameness. A diagnosis of bilateral medially luxating patellae was made based on clinical and radiographic findings. The chondrodysplasia in this case was atypical in its hindlimb skeletal deformity along with atypical osteopaenia. The case was successfully managed with trochlear sulcoplasty and tibial tuberosity transposition; due to reduced bone quality, the tibial tuberosity was secured with a locking plate (ALPS; Kyon, Inc, Zurich, Switzerland). To the authors’ knowledge, treatment of patellar luxation in chondrodysplastic Alaskan Malamutes has not been previously reported.
Seismic signatures reveal persistence of soil compaction

AbstractA well‐developed soil structure is a key attribute of a productive and functioning soil. Evidence shows that subtle changes in the spatial arrangement and binding of soil constituents impart large changes in soil mechanical and hydraulic properties and associated ecological services. However, these features remain difficult to quantify at spatial scales relevant for agricultural management. In this work, we propose a pedophysical model to interpret macroscopic seismic properties in terms of soil structure. The model captures subtle soil mechanical traits accounting for soil plastic deformation due to compaction. In order to evaluate the model, we use data from field monitoring at an experimental site that revealed elevated seismic velocities in plots that were compacted 5 yr prior to our measurements. Our results show that P‐wave velocities carry a strong imprint of soil compaction and are well predicted by the proposed model. The model infers contact areas between aggregates that are nearly threefold larger for compacted than for non‐compacted soils, indicating that soils have not recovered from compaction. The study illustrates the potential of seismic methods to identify chronic compaction at field scale.

AbstractAlthough cosmic‐ray neutron sensing (CRNS) is probably the most promising noninvasive proximal soil moisture measurement technique at the field scale, its application for hydrological simulations remains underexplored in the literature so far. This study assessed the use of CRNS to inversely calibrate soil hydraulic parameters at the intermediate field scale to simulate the groundwater recharge rates at a daily timescale. The study was conducted for two contrasting hydrological years at the Guaraíra experimental basin, Brazil, a 5.84‐km², a tropical wet and rather flat landscape covered by secondary Atlantic forest. As a consequence of the low altitude and proximity to the equator low neutron count rates could be expected, reducing the precision of CRNS while constituting unexplored and challenging conditions for CRNS applications. Inverse calibration for groundwater recharge rates was used based on CRNS or point‐scale soil moisture data. The CRNS‐derived retention curve and saturated hydraulic conductivity were consistent with the literature and locally performed slug tests. Simulated groundwater recharge rates ranged from 60 to 470 mm yr–1, corresponding to 5 and 29% of rainfall, and correlated well with estimates based on water table fluctuations. In contrast, the estimated results based on inversive point‐scale datasets were not in alignment with measured water table fluctuations. The better performance of CRNS‐based estimations of field‐scale hydrological variables, especially groundwater recharge, demonstrated its clear advantages over traditional invasive point‐scale techniques. Finally, the study proved the ability of CRNS as practicable in low altitude, tropical wet areas, thus encouraging its adoption for water resources monitoring and management.
Factorization and transverse phase-space parton distributions
Authors: Wu Bin 
Published: July 2021

Abstract
We first revisit impact-parameter dependent collisions of ultra-relativistic particles in quantum field theory. Two conditions sufficient for defining an impact-parameter dependent cross section are given, which could be violated in proton-proton collisions. By imposing these conditions, a general formula for the impact-parameter dependent cross section is derived. Then, using soft-collinear effective theory, we derive a factorization formula for the impact-parameter dependent cross section for inclusive hard processes with only colorless final-state products in hadron and nuclear collisions. It entails defining thickness beam functions, which are Fourier transforms of transverse phase-space parton distribution functions. By modelling non-perturbative modes in thickness beam functions of large nuclei in heavy-ion collisions, the factorization formula confirms the cross section in the Glauber model for hard processes. Besides, the factorization formula is verified up to one loop in perturbative QCD for the inclusive Drell-Yan process in quark-antiquark collisions at a finite impact parameter.

Published: July 2021

ZusammenfassungDie gezielte Therapie epileptischer Ereignisse und im Speziellen des Status epilepticus (SE) setzt das sichere Erkennen der Krankheitsbilder voraus, wofür gerade bei Formen mit vorwiegend nichtmotorischen Symptomen klinische und elektroenzephalographische Expertise notwendig ist. Die im Jahr 2020 erfolgte Fortschreibung der deutschen Leitlinie zur Behandlung des SE hält an der streng stufengerechten Therapie fest, die eskalierend die Anwendung von Benzodiazepinen, spezifischen Antiepileptika und Anästhetika vorsieht. Bisher ist die Eingrenzung eines in den allermeisten Fällen wirksamen sowie zugleich sicheren und interaktionsfreien Antiepileptikums nicht gelungen. Individuelle Vorerkrankungen und aktuelle Begleitumstände gehen daher genauso wie Erfahrungen des Behandlerteams in die differenzierte Behandlung des SE ein. Insbesondere bei therapierefraktären Formen des SE erweist sich die Therapie als durchaus kompliziert und hat regelhaft intensivmedizinische Implikationen. Mithin ergeben sich im Zuge der modernen SE-Behandlung zahlreiche interdisziplinäre Schnittstellen. Zukünftige wissenschaftliche Fragstellungen werden sich u. a. mit der optimalen Therapie des nonkonvulsiven SE und hier v. a. dem Ausmaß und dem Zeitpunkt von adäquaten Therapieschritten sowie mit assoziierten ethischen Fragen einer Therapieeskalation beschäftigen.
Microstructure, hardness, and wear resistance of AZ91 magnesium alloy produced by friction stir processing with air-cooling
Authors: Iwaszko Józef , Kudła Krzysztof 
Published: July 2021

AbstractFriction stir processing (FSP) was used to modify the surface layer of the AZ91 magnesium alloy. The treatment was carried out using a jet cooling nozzle, generating a stream of cold air and enabling intensive cooling of the friction stir processed (FSPed) zone. Single-pass FSP was carried out using a tool rotational speed of 500 rpm and travel speed of 30 mm/min. The treatment was conducted using a truncated cone-shaped tool with a threaded side surface. Strong grain refinement and microstructural changes typical for FSP were found in all the samples. Very fine, equiaxed recrystallized grains dominated in the stirring zone. In the samples modified with the jet cooling nozzle, greater grain refinement was obtained than in the case of naturally cooled material. The average grain size in the surface part of the stirring zone was 1.4 μm and 9 μm in the samples with air-cooling and with natural cooling, respectively. Both the naturally cooled specimen and air-cooled specimen were characterized by a distinctly higher hardness than the base material. The average Vickers hardness in the stirring zone was 91 HV0.1 in the FSPed sample with the air-cooling system and 85.5 HV0.1 with natural cooling, respectively. The average Vickers hardness of the as-cast alloy was 64 HV0.1. Slightly higher wear resistance of the FSPed samples using a jet cooling nozzle was found in relation to the naturally cooled sample. Based on the conducted research, high efficiency of the jet cooling nozzle in cooling the modified zone during friction stir processing was found.
Leaching Rate of Polychlorinated Biphenyls (PCBs) from Marine Paint Chips

Published: July 2021

AbstractPolychlorinated biphenyls (PCBs) were added to certain marine vessel bottom paints as a plasticizer to improve the adhesion and durability of the paint. The most common PCB formulation used to amend such paints was Aroclor 1254. Fugitive Aroclor-containing paint chips generated from vessel maintenance and repair operations represent a potential source of PCB contamination to sediments. Limited published studies indicate that Aroclor-containing paint is largely inert and exhibits low PCB leaching into water; however, the rate and degree of leaching of PCBs from paint chips have not been directly studied. This laboratory-based study evaluated the rate and extent of leaching of PCBs from paint chips into freshwater. The results of this investigation demonstrate that the rate of PCB dissolution from paint chips decreased rapidly and exponentially over time. Based on this study, it is estimated that the rate of leaching of PCBs from paint chips would cease after approximately 3 years of exposure to water. When all leachable PCBs were exhausted, it is estimated that less than 1% of the mass of PCBs in the paint chips was amenable to dissolution. The results of this experiment suggest that Aroclor-containing paint chips found in sediments are likely short-term sources of dissolved-phase PCB to pore or surface waters and that the majority of the PCBs in paint chips remain in the paint matrix and unavailable for partitioning into water.

Sclerochronology in the Southern Ocean
Authors: Roman Gonzalez Alejandro 
Published: July 2021

AbstractThis manuscript aims to provide a comprehensive review of the work done by Antarctic sclerochronology research across different taxa (arthropods, bivalves, brachiopods, bryozoans, cephalopods, hard and soft corals, gastropods, echinoderms and teleost fish), provide an analysis of current challenges in the discipline and start a discussion of what sclerochronology can offer for Antarctic research in future. The Southern Ocean ecosystem remains largely unstudied in part for its remoteness, extreme climate and strong seasonality. This lack of knowledge, some of it even on basic biological information, it is especially worrying due to ongoing climate-driven changes that the Southern Ocean ecosystem is experiencing. Lack of long-term in situ instrumental series has also being a detriment to understand long-term feedbacks between the physical environment and the ecosystem. Sclerochronology, the study of periodic accretional patterns in the hard body structures of living organisms, has contributed to a wide range of Antarctic research disciplines (e.g. paleoclimate reconstructions, population structure analysis, environmental proxies). This review highlights a disparity in research focus by taxa with some groups (e.g. bivalves, teleost fish) attracting most of the research attention, whereas other groups (e.g. gastropod) have attracted much little research attention or in some cases it is almost non-existent (e.g. echinoderms). Some of the long-lived species considered in this review have the potential to provide the much-needed high-resolution eco-environmental proxy data and play an important role in blue carbon storage in the Sothern Ocean. Another issue identified was the lack of cross-validation between analytical techniques.

AbstractTo improve soil health and to aid in climate change mitigation, the quantity of soil organic matter (SOM) should be maintained or increased over the long run. In doing so, not only the total quantity of SOC but also the stability of SOC must be considered. Stability of SOC increases as a function of resistance to microbial decomposition or microbial substrate use efficiency through chemical, biological, and physical mechanisms including humification, hydrophobic moieties, molecular diversity, and formation of macroaggregates. One of the mechanisms that enhance stability confers changes in the distribution of C functional groups of SOM. To better understand and quantify how these changes are influenced by agricultural management practices, we collected 670 pairwise data from the body of literature that has evaluated changes in the distribution of C functional groups of SOM measured by solid-state 13C NMR spectroscopy. The types of agricultural managements discussed herein include (1) fertilization, (2) tillage, (3) crop rotation, (4) grazing, and (5) liming practices. Our meta-analyses show that these practices modify the distribution of C functional groups of SOM. Fertilization practices were associated with increased O-alkyl groups. Tillage resulted in increases in the SOC consisted of aromatic and carbonyl groups. Crop rotations, especially legume-based rotations, were found to increase the proportion of aromatic groups. Although there are fewer publications on tillage and crop rotation than on fertilization practices, the distribution of C functional groups may be more influenced by crop rotation and tillage practices than fertilization management—and should be a focus of future research.
Best Fit Bin Packing with Random Order Revisited
Authors: Albers Susanne , Khan Arindam , Ladewig Leon 
Published: July 2021

AbstractBest Fit is a well known online algorithm for the bin packing problem, where a collection of one-dimensional items has to be packed into a minimum number of unit-sized bins. In a seminal work, Kenyon [SODA 1996] introduced the (asymptotic) random order ratio as an alternative performance measure for online algorithms. Here, an adversary specifies the items, but the order of arrival is drawn uniformly at random. Kenyon’s result establishes lower and upper bounds of 1.08 and 1.5, respectively, for the random order ratio of Best Fit. Although this type of analysis model became increasingly popular in the field of online algorithms, no progress has been made for the Best Fit algorithm after the result of Kenyon. We study the random order ratio of Best Fit and tighten the long-standing gap by establishing an improved lower bound of 1.10. For the case where all items are larger than 1/3, we show that the random order ratio converges quickly to 1.25. It is the existence of such large items that crucially determines the performance of Best Fit in the general case. Moreover, this case is closely related to the classical maximum-cardinality matching problem in the fully online model. As a side product, we show that Best Fit satisfies a monotonicity property on such instances, unlike in the general case. In addition, we initiate the study of the absolute random order ratio for this problem. In contrast to asymptotic ratios, absolute ratios must hold even for instances that can be packed into a small number of bins. We show that the absolute random order ratio of Best Fit is at least 1.3. For the case where all items are larger than 1/3, we derive upper and lower bounds of 21/16 and 1.2, respectively.
The Integration of People Convicted of a Sexual Offence Into the Community and Their (Risk) Management
Authors: McCartan K. F. , Richards K. 
Published: July 2021

AbstractPurpose of ReviewWe are reviewing recent research into the community integration of men convicted of a sexual offence and their (risk) management. This is a high-profile political issue that binds together research in psychology, criminology, politics, health, public health, and policy studies. The review will demonstrate that a multi-disciplinary, life course, EpiCrim-oriented approach is the most effective way of reducing re-offending and promoting desistance in this population.Recent FindingsResearch demonstrates that life course development, especially from psychology and criminology, has an impact on whether people sexually offend or not. Therefore, to understand sexual offending behaviour, we need to look at the aetiology of said behaviour from a nature and a nurture perspective. Therefore, we need to use an Epidemiological Criminology (a marriage of Public Health and criminology) approach that works at all four stages of the Socio-Ecological Model (SEM) (individual, interrelationship, community, and societal). The research encourages a person first approach, that we look at Adverse Childhood Experiences and past trauma in the lives of men who sexually offend and use this, in conjunction with strength-based approaches, to inclusively integrate them into society.SummaryThe prevention of sexual offending, both first time offending, and relapse prevention require a multi-level, multi-disciplinary approach. Successful desistance from sexual offending is as much about the community and society as it is about the individual.
Mental Health Outcomes of Unaccompanied Refugee Minors: a Rapid Review of Recent Research
Authors: Bamford Jordan , Fletcher Mark , Leavey Gerard 
Published: July 2021

Abstract
Purpose
To examine mental health outcomes of unaccompanied refugee minors during global policy shift. Additionally, to consider mental health service delivery and placement type for this group.

Methods
A rapid systematic search of research published since 2018 which related to mental health outcomes of unaccompanied refugee minors. Data extracted, risk of bias assessed and outcomes reviewed qualitatively.

Research Findings
We found 181 papers, of which 14 met inclusion criteria. This review found consistently high levels of PTSD and PTSS among URMs in various contexts. Exposure to trauma, being unaccompanied (compared to accompanied), being female and being older are associated with poor outcomes. Depression and anxiety were consistently high among URMs and associated with discrimination, limited language attainment and daily hassles.

Summary
High rates of mental illness and symptoms among unaccompanied refugee minors were consistent across national and settlement contexts but the quality of the evidence is variable with significant heterogeneity of assessment. We relate persistence of poor mental health outcomes with problems accessing mental health services and discuss the role of key post-migration factors influencing outcomes—in particular placement type and the use of detention centres.
Nimesulide Determination on Carbon Black-Nafion Modified Glassy Carbon Electrode by Means of Adsorptive Stripping Voltammetry
Authors: Łysoń Marcelina , Górska Anna , Paczosa-Bator Beata , Piech Robert 
Published: July 2021

AbstractAdsorptive Stripping Voltammetric method for Nimesulide (NIM) determination was developed. As a working electrode, glassy carbon electrode (GCE) modified with carbon black and Nafion (CB-Nafion GCE) was used. All measurements were carried out in 0.1 M acetate buffer (pH 4.6). Conducted experiments allowed to optimize differential pulse voltammetry (DPV) instrumental parameters: sampling and waiting time ts = tw = 10 ms, step potential Es = 4 mV, and pulse amplitude ΔE = 50 mV. The best results were obtained for preconcentration potential and time equal to 400 mV and 20 s, respectively. Limit of detection was calculated and was equal to 0.14 µM for 20-s preconcentration time and 0.06 µM for 40-s preconcentration time. In order to prove the applicability of the developed method, concentration of nimesulide in pharmaceutical products was determined. Calculated recoveries were in the range 94–99%, which indicates that the method might be assumed as accurate. Coefficient of variation was equal to 5.0% (n = 7, NIM concentration 1 µM) Obtained results of NIM determination were in good agreement with the content declared by producers.
