Two sequential experiments examined the effects of abrasive grit on seedlings of grass weeds and young shoots of perennial weeds. First, four types of grit derived from agricultural residues (bone meal, eggshell, hazelnut shell, and sugar beet pulp) were tested under high air pressure in a controlled environment for their abilities to abrade seedlings of an annual grass, Setaria faberi Herrm., and the perennials Festuca arundinacea Schreb., Poa pratensis L., and Elymus repens (L.) Gould. Differing grit particle sizes and amounts, as well as weed seedling stages, were examined for efficacy after abrasion by each type of grit. Second, hazelnut shell grit was used to control P. pratensis and Taraxicum officinale Weber in field trials with aronia (Aronia melanocarpa [Michx.] Elliott), which is a new, shrubby, berry crop in the midwestern USA. Grit weeding was compared to two other treatments: manual weeding (hand-hoeing + hand-pulling) and no weed control (weedy check) over two years. In the grit comparison experiment, control of S. faberi was highest for egg-shell grit (63–100% across grit particle sizes, rates, and seedling stages) and least for sugar beet pulp (17–97%). The former grit had the highest bulk density of all grits, and the latter had the lowest bulk density. For damage to perennial weeds, egg-shell grit performed best (17–80% control) and bone meal least (10–47% control). Elymus repens was controlled better than other perennial grasses, especially by eggshell grit (up to 73% control) and hazelnut shell grit (up to 67% control) with particle sizes of 1–2 mm. In the aronia experiment, both grit abrasion and manual weeding achieved comparable levels of weed suppression (≥87%) and required similar amounts of cumulative seasonal time spent weeding (3–4 min per shrub). Thus, applications of abrasive grit derived from agricultural residues are potential alternatives for non-chemical management of weeds in aronia and, perhaps, in other high-value perennial crops.

The American crocodile Crocodylus acutus occurs across the Americas, with its northernmost distribution being in South Florida, USA. This species has undergone severe declines across its range and is categorized globally as Vulnerable on the IUCN Red List and as Threatened on the U.S. Federal Endangered Species List. Long-term monitoring studies in the USA have documented a shift in American crocodile nesting activity and an expansion of its range throughout the southern and eastern coasts of South Florida. However, no successful American crocodile nests have been recorded until now on the west coast of South Florida. Here we document the American crocodile nest monitoring conducted during 1997–2021 at Rookery Bay National Estuarine Research Reserve and the first successful nest from the west coast of South Florida for C. acutus. Marco Airport and McIlvane Marsh are the two main American crocodile nesting areas identified at the Reserve, with 92 nests and 3,586 eggs recorded during 1997–2021. We found most nests at Marco Airport (95.7%) and only four nests (4.3%) at McIlvane Marsh. To date, none of the nests found at Marco Airport have produced successful hatchlings. In contrast, hatchlings have been produced at McIlvane Marsh since nests were first documented there in 2020. We discuss the implications of our findings in terms of the future conservation of the species.

Background
Disruptive behavior disorders (DBD) are heterogeneous at the clinical and the biological level. Therefore, the aims were to dissect the heterogeneous neurodevelopmental deviations of the affective brain circuitry and provide an integration of these differences across modalities.
MethodsWe combined two novel approaches. First, normative modeling to map deviations from the typical age-related pattern at the level of the individual of (i) activity during emotion matching and (ii) of anatomical images derived from DBD cases (n = 77) and controls (n = 52) aged 8–18 years from the EU-funded Aggressotype and MATRICS consortia. Second, linked independent component analysis to integrate subject-specific deviations from both modalities.
ResultsWhile cases exhibited on average a higher activity than would be expected for their age during face processing in regions such as the amygdala when compared to controls these positive deviations were widespread at the individual level. A multimodal integration of all functional and anatomical deviations explained 23% of the variance in the clinical DBD phenotype. Most notably, the top marker, encompassing the default mode network (DMN) and subcortical regions such as the amygdala and the striatum, was related to aggression across the whole sample.
ConclusionsOverall increased age-related deviations in the amygdala in DBD suggest a maturational delay, which has to be further validated in future studies. Further, the integration of individual deviation patterns from multiple imaging modalities allowed to dissect some of the heterogeneity of DBD and identified the DMN, the striatum and the amygdala as neural signatures that were associated with aggression.

Summary
This chapter synthesises insights from the Deep Decarbonisation Pathways Project (DDPP), which provided detailed analysis of how 16 countries representing three-quarters of global emissions can transition to very low-carbon economies. The four ‘pillars’ of decarbonisation are identified as: achieving low or zero-carbon electricity supply; electrification and fuel switching in transport, industry and housing; ambitious energy efficiency improvements; and reducing non-energy emissions. The chapter focuses on decarbonisation scenarios for Australia. It shows that electricity supply can be readily decarbonised and greatly expanded to cater for electrification of transport, industry and buildings. There would be remaining emissions principally from industry and agriculture, these could be fully compensated through land-based carbon sequestration. The analysis shows that such decarbonisation would be consistent with continued growth in GDP and trade, and would require very little change in economic structure of Australia’s economy. Australia is rich in renewable energy potential, which could re-enable new industries such as energy-intensive manufacturing for export

The WISSARD (Whillans Ice Stream Subglacial Access Research Drilling) traversable hot-water drill system was designed to create various-diameter ice boreholes to a depth of >800 m, with most major components being controllable from a single user interface. The drill control system operates four low-pressure pumps for water generation and circulation, two hot-water generation units containing a total of six diesel burner modules with integrated high-pressure pumps, three winches (one with independent level-wind motor), a four-motor linear traction drive, and a large number of analog and digital sensors to monitor system performance and cleanliness. Due to development time constraints the control system design focused on utilizing commercial off-the-shelf components, while being highly modular, easily expandable and rapidly deployable. Additional emphasis was placed on providing redundant manual operator controls and maintaining a low degree of system automation to avoid dependence on software control loops for first-season deployment. The result of this design paradigm was a control system that was taken from concept to full operation in <6 months, successfully performing in the field without insurmountable problems.

A new, clean, hot-water drill system (HWDS) was developed by the Science Management Office, University of Nebraska-Lincoln, for use in the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project to gain access to Subglacial Lake Whillans beneath ∼800 m of ice in West Antarctica. One primary borehole was drilled into the basal ice environment of Subglacial Lake Whillans during the initial field season in 2012/13. This paper describes the process of designing, fabricating, assembling, shipping, testing, commissioning and traversing the WISSARD HWDS leading up to the first scientific use of the system.

Analysis of response and recovery efforts to disasters over the past 2 decades has identified a consistent gap that plagues the nation in regard to persons with access and functional needs. This gap can be highlighted by Hurricane Katrina, where the majority of those killed were a part of the access and functional needs population. After a disaster, many individuals with access and functional needs require assistance recovering but often have difficulty accessing services and resources. These difficulties are due to a combination of issues, such as health problems and the disruption of community support services. We sought to help bridge this gap by focusing on strategic and operational methods used while planning for the whole community. This article highlights the many partnerships that must be fostered for successful whole-community planning. These partnerships include, but are not limited to, local government departments, health agencies, nonprofit and nongovernmental organizations, and other volunteer organizations. We showcase these methods by using a developmental Post-Disaster Canvassing Plan to highlight planning methods that may aid jurisdictions across the United States in disaster planning for the whole community.

Accurate estimates of body mass in fossil taxa are fundamental to paleobiological reconstruction. Predictive equations derived from correlation with craniodental and body mass data in extant taxa are the most commonly used, but they can be unreliable for species whose morphology departs widely from that of living relatives. Estimates based on proximal limb-bone circumference data are more accurate but are inapplicable where postcranial remains are unknown. In this study we assess the efficacy of predicting body mass in Australian fossil marsupials by using an alternative correlate, endocranial volume. Body mass estimates for a species with highly unusual craniodental anatomy, the Pleistocene marsupial lion (Thylacoleo carnifex), fall within the range determined on the basis of proximal limb-bone circumference data, whereas estimates based on dental data are highly dubious. For all marsupial taxa considered, allometric relationships have small confidence intervals, and percent prediction errors are comparable to those of the best predictors using craniodental data. Although application is limited in some respects, this method may provide a useful means of estimating body mass for species with atypical craniodental or postcranial morphologies and taxa unrepresented by postcranial remains. A trend toward increased encephalization may constrain the method's predictive power with respect to many, but not all, placental clades.

Introduction
Emergency medicine point-of-care ultrasonography (EM-PoCUS) is a core competency for residents in the Royal College of Physicians and Surgeons of Canada and College of Family Physicians of Canada emergency medicine (EM) training programs. Although EM-PoCUS fellowships are currently offered in Canada, there is little consensus regarding what training should be included in a Canadian EM-PoCUS fellowship curriculum or how this contrasts with the training received in an EM residency.
ObjectivesTo conduct a systematic needs assessment of major stakeholders to define the essential elements necessary for a Canadian EM-PoCUS fellowship training curriculum.
MethodsWe carried out a national survey of experts in EM-PoCUS, EM residency program directors, and EM residents. Respondents were asked to identify competencies deemed either nonessential to EM practice, essential for general EM practice, essential for advanced EM practice, or essential for EM-PoCUS fellowship trained (‘‘expert’’) practice.
ResultsThe response rate was 81% (351 of 435). PoCUS was deemed essential to general EM practice for basic cardiac, aortic, trauma, and procedural imaging. PoCUS was deemed essential to advanced EM practice in undifferentiated symptomatology, advanced chest pathologies, and advanced procedural applications. Expert-level PoCUS competencies were identified for administrative, pediatric, and advanced gynecologic applications. Eighty-seven percent of respondents indicated that there was a need for EM-PoCUS fellowships, with an ideal length of 6 months.
ConclusionThis is the first needs assessment of major stakeholders in Canada to identify competencies for expert training in EM-PoCUS. The competencies should form the basis for EM-PoCUS fellowship programs in Canada.

The aim of this meeting was to obtain a consensus on what constitutes good research practice in posttraumatic stress disorder (PTSD). Objectives were to review relevant parameters of trials, such as the patients recruited, the means of assessing PTSD at baseline, and the change in symptomatology in response to treatment, and to reach a consensus on the most appropriate parameters to use in future research. The bases for the discussion were the 1995 National Institute of Mental Health (NIMH) and the National Center for PTSD consensus on the assessment of PTSD, results of drug treatment trials, and information on the assessment scales used in PTSD research.

Summary
Executive summary
Nature of the problem
Farms represent operational units which determine N-use efficiency and incorporation into products and, collectively, at the wider scale, determine the extent of environmental losses from agriculture.
The basic principles and objectives of using N, from whatever source, pertain to different systems across the wide range of farming types across Europe.
In addition to managing external inputs (fertilisers), there is much opportunity to improve N transfers within the farm. Mineral fertilisers are added to balance supply/demand for crops. Some systems rely on legume-N which, once incorporated into farm cycles, behaves in the same way as other N forms.
Approaches
Farm N cycles, their constituent parts and controlling influences are described and generalised principles identified.
Farm budgets for a range of systems, focussing on typical practice in NW Europe are shown which illustrate some general, important differences between farming systems.
Key findings/state of knowledge
Benefits of using N effectively are far reaching with immediate impact in promoting production. Use of N also provides an effective and flexible management tool for farmers.
Crop N requirements are determined from response curves and economic optima. Advice is supplied to farmers from various sources but the extent to which it is taken depends on many factors. New technologies are available to improve N-use efficiency. The basis of good N management is to optimise efficiency of added and soil N by increasing the temporal and spatial coincidence between availability and uptake of N.

Significant shifts of the frequency of the Raman spectra of the tangential mode of single walled carbon nanotubes (SWNTs) and fluorinated tubes (FSWNTs) in composites of polybutadiene (PB) were observed relative to the pristine SWNTs indicative of the interaction between the polymer and the SWNTs. Proton NMR line width measurements demonstrate partial suppression of polymer segmental motion for both types of nanotube composites and spin-lattice relaxation results indicate that short time-scale localized motions are also affected by SWNT inclusion, more so for FSWNTs. Hardness measurements as a function of wt% SWNTs and FSWNTs in the polymer show larger enhancements of hardness in the composite with the fluorinated tubes.

Our activities are focused upon the experimental demonstration of deep nulling in the mid-IR over a wide bandpass. Specifically, our near-term goal is demonstrating a contrast of 10$^{-6}$ at 10 $\mu$m with a 25% spectral bandwidth. To meet this goal, several areas of technology development are required. These include: single-mode infrared fibers, bright infrared sources, laser path-length and tip/tilt metrology, and improvements to detection sensitivity. Progress in each of these areas of technical development will be reviewed as well as their impact on the overarching technical milestones.

Processing and measurement of 200 biomedical samples has provided an opportunity to better understand the characteristics of accelerator mass spectrometry (AMS) analysis of such samples. We have utilized established procedures (Vogel 1992) and developed new methods for handling various biological samples. We have included secondary standards of known isotope ratio for all assays. A method of determining maximum precision for each unknown sample value is also reported. The presented data are an update of the ongoing radiocarbon AMS biomedical program at Purdue University.
