Published: July 2015

Aim of the study: The objective of this study was to evaluate recent technological improvements to forest bundlers: a new cutting device with shears and a mechanism which allows the bundling pressure to be changed by the driver.Area of study: eucalyptus plantations in Northern Spain.Material and Methods: Several time studies were performed in order to compare and calculate productivity depending on the machine: John Deere bundler working with the traditional chainsaw and Monra bundler equipped with the technological improvements of shears and adjustable bundling pressure.Research highlights: Significant differences were found between cutting devices (shears and chainsaw) and between the Monra working at maximum pressure and at lower pressure. Shears were shown to be a more robust and reliable cutting device, with 1.02 cutting attempts per bundle compared to 1.55 with chain saw. The use of shears made the loading more efficient as it eliminates the need to shake the residues before feeding the bundler. A great advantage of this technological improvement is that it can be incorporated into other machines and thus improve bundling efficiency.In spite of this, working at standard bundling pressure, the productivity of the Monra bundler is only 3.2 per cent higher than that of the John Deere due to the fact that in the latter bundling is faster and it produces bundles with significantly more dry mass.For the Monra bundler, the option of producing lighter bundles further reduced productivity compared to when standard weight bundles are produced. However, it would be of interest to study the effect of the machine working at various pressures in order to optimize the work system. It is possible that working at higher pressures would have advantages in terms of increasing transport efficiency.Keywords: bundler; time study; shear; cutting device; slash collection; forest biomass.
La métaphysique de la nature à l’Académie de Berlin
Authors: Leduc Christian 
Published: July 2015

Dans le présent article, je montre que Maupertuis et Euler proposent une conception contrastée de la métaphysique de la nature. Il s’agit principalement pour eux de repositionner la cosmologie par rapport aux sciences de la nature. Au lieu de considérer la métaphysique comme étant au fondement des théories scientifiques, comme le supposent Descartes, Wolff et, d’une certaine manière, Kant, ou simplement d’interdire l’idée même d’une cosmologie, comme le stipulerait à la même époque d’Alembert, Maupertuis et Euler, renversent l’ordre des disciplines pour donner aux sciences physiques une primauté sur la métaphysique. Ce repositionnement entraîne évidemment plusieurs questions : d’abord, de quelle manière les théories scientifiques peuvent-elles valider ou infirmer un principe métaphysique ? Plus important encore, quel rôle incombe à la métaphysique de la nature, étant donné que les sciences possèdent non seulement une autonomie théorique, mais même une priorité sur les réflexions ontologiques. Il semblerait d’ailleurs que la métaphysique se réduise, pour ces deux philosophes, au seul domaine du cosmologique, en particulier aux questions qui concernent la force et le principe de moindre action, au statut ontologique de l’espace et du temps et aux déterminations de la matière que sont l’étendue, l’inertie, l’impénétrabilité et le mouvement.
Iliac Crest Herniation Secondary to Autogenous Bone Grafting Found on Osteopathic Examination

Published: July 2015

Abstract
Surgical repair of difficult or nonunion fractures is frequently performed with autogenous bone grafts, most commonly from the iliac crest. Complications from this procedure may include vessel injury, nerve injury, pelvic instability, bowel herniation, and ileus. The authors report a case of iliac crest herniation in a patient presenting with a small-bowel obstruction 2 years after anterior iliac crest graft harvest for an open reduction and internal fixation repair of a right humeral shaft fracture. An emergency operation revealed that the right colon had herniated through an opening in the right iliac crest. The appendix had adhered to new osseous bone formed postoperatively, requiring an appendectomy. The hernia defect was successfully repaired with polypropylene mesh. A high index of suspicion for graft site herniation is needed for patients with a history of iliac crest bone grafting who present with symptoms of abdominal pain, flank or hip pain, ileus, or small-bowel obstruction.

Abstract

There is a rapid, global push for wind energy installation. However, large numbers of bats are killed by turbines each year, raising concerns about the impacts of wind energy expansion on bat populations. Preventing turbine blades from spinning at low wind speeds, referred to as curtailment, is a method to reduce bat fatalities, but drawing consistent inference across studies has been challenging.

We compiled publicly available studies that evaluated curtailment at six wind energy facilities in North America across 10 years. We used meta‐regression of 29 implemented treatments to determine fatality reduction efficacy as well as sources of variation influencing efficacy. We also estimated species‐specific fatality reduction for three species that comprise most fatalities in North America: hoary bat (Lasiurus cinereus), eastern red bat (Lasiurus borealis) and silver‐haired bat (Lasionycteris noctivagans).

We found that curtailment reduced total bat fatalities by 33% with every 1.0 ms−1 increase in curtailment wind speed. Estimates of the efficacy for the three target species were similar (hoary bats: 28% per ms−1, 95% CI: 0.4%–48%, eastern red bats: 32% per ms−1, 95% CI: 13%–47% and silver‐haired bats: 32% per ms−1, 95% CI: 3%–53%).

Across multiple facilities and years, a 5.0 ms−1 cut‐in speed was estimated to reduce total bat fatalities by an average of 62% (95% CI: 54%–69%). Mortality reductions at individual facilities in any given year were estimated to fall between 33%–79% (95% prediction interval). Inter‐annual differences rather than inter‐site or turbine characteristics accounted for most of the variation in efficacy rates. Species‐specific average mortality reduction at 5.0 ms−1 curtailment wind speed was 48% (95% CI: 24%–64%) for hoary bats, 61% (95% CI: 42%–74%) for eastern red bats and 52% (95% CI: 30%–66%) for silver‐haired bats.

Practical implication. curtailment reduced bat mortality at wind turbines in this North American study. Efficacy increased proportionally as curtailment speed is raised, and patterns and rates of efficacy were similar across species. This indicates that curtailment is an effective strategy to reduce bat fatalities at wind energy facilities, but exploration of further refinements could both minimize bat mortality and maximize energy production.

AbstractScintillators can convert the ionizing radiation into visible light and are crucial in X/γ‐ray detectors. Commercial detectors often use multiple scintillators with photodetector arrays, where optical crosstalk can degrade the performance. Chiral scintillators, emitting circularly polarized light, offer a promising solution for regulating the direction of light propagation to enhance X‐ray detecting merits. Here novel chiral metal‐organic polymers have been developed via photopolymerization, using chiral polymeric monomers and 0D Mn(II)‐based organic‐metal halide hybrid scintillators, achieving luminescence dissymmetry factors (glum) of 5.823 × 10−2 and −2.877 × 10−2. Two such scintillators, (atpp)2MnCl4·0.5H2O (MnCl4−1) and (atpp)2MnBr4 (MnBr4−2), exhibit excellent X‐ray scintillation rooted in tetrahedral [MnX4]2− crystal field. Compound MnBr4−2, with heavier bromine atoms, shows superior performance with a detection limit of 0.117 µGyair s−1, compared to 0.330 µGyair s−1 of MnCl4−1, both surpassing the medical diagnostic standard of 5.50 µGyair s−1. The chiral metal‐organic polymer film derived from MnBr4−2 has achieved a resolution up to 14.84 lp mm−1, exceeding medical standards for dental (2.0 lp mm−1) and breast cancer (10.0 lp mm−1) imaging. These advancements in chiral scintillators hold significant promise for high‐resolution X‐ray medical imaging applications.

AbstractAn efficient and stable electrocatalyst is key for the production of green hydrogen using water electrolysis. However, the weak dissociation ability of Pt‐based catalysts, resulting in slow kinetics severely hampers its applications in alkali medium. Herein, a simple “coincident reduction” strategy is reported to grow highly dispersed Ru‐Pt heterogeneous bimetallic nanoparticles on reduced graphene oxide (RuxPty@rGO) for efficient pH‐universal hydrogen evolution. RuxPty@rGO has superior catalytic activity at all pH values due to the synergistic effect between Ru and Pt and the ultra‐small nanoparticle. In particular, the catalyst with 13.6 wt% of noble metal (Ru1Pt2@rGO) has low overpotentials of 9, 6, and 36 mV at 10 mA cm−2 in 1 m KOH, 0.5 m H2SO4 and 1 m phosphate buffer solution (PBS), respectively, which outperformances monometallic counterparts and comparable to the best bimetallic catalysts ever reported. The catalyst is highly stable because of the strong bonding between the bimetallic nanoparticle and rGO. Mechanism studies show that Ru1Pt2@rGO has a faster Volmer–Tafel mechanism in alkali, high‐efficient H+ transfer and increased H adsorption ability in acid, resulting in superior reaction kinetics. This work provides a new route for mass production of high‐performance catalysts for practical applications at all pH values.

AbstractSkin is the largest organ in the human body, and it is also the most important natural barrier. However, some accidents can cause skin damage. Bacterial infections and inflammatory reactions can hinder wound healing. Therefore, eliminating bacterial infections and regulating oxidative stress are essential. The use of antibiotics is no longer sufficient because of bacterial resistance. The development of new nanomaterials provides another way of thinking about bacterial drug resistance. In this study, bismuth selenide is modified with polyethylpyrrolidone to obtain a 2D nanomaterial with negligible toxicity and then added to a sodium polyacrylate hydrogel, which is nontoxic and has strong tissue adhesion and a weak antibacterial effect. To further enhance antibacterial performance, photothermal therapy is a good strategy. Under near‐infrared light, Bi2Se3/PAAS shows a strong bactericidal effect. Bi2Se3/PAAS hydrogels also have certain antioxidant effects and are used to remove excess free radicals from wound infections. The effective therapeutic effect of Bi2Se3/PAAS/NIR on methicillin‐resistant Staphylococcus aureus (MRSA) infection is further verified in animal models. Transcriptome analysis reveals that the Bi2Se3/PAAS hydrogel improves the function of vascular endothelial cells, regulates glucose and lipid metabolism, and promotes the healing of infected wounds.

Published: August 2024

AbstractCu‐doped ZnO nanoparticle‐loaded cellulose nanofiber membranes are investigated for their potential photocatalytic and antibacterial properties. ZnO nanoparticles, both undoped and doped with copper, are synthesized by the co‐precipitation process, afterward immobilized onto cellulose nanofibers through the utilization of a dip‐coating technique. Methylene blue (MB) removal is evaluated to inspect the effectiveness of photocatalysts in both UV and Xenon lighting conditions. The morphology and structure of the composite cellulose nanofibers loaded with photocatalysts are then examined using FE‐SEM, TEM, XRD, FTIR, and UV–vis characterizations. Under visible light, the self‐cleaning effects of organic compounds are measured, presenting more than 50% of discoloration for various organic stains. The antibacterial activity is assessed using the Kirby–Bauer disc diffusion method and the plate counting method against the gram‐positive Staphylococcus aureus (S. aureus) and gram‐negative Escherichia coli (E. coli) bacteria. The current study shows that cellulose nanofibers coated with Cu‐doped ZnO nanoparticles exhibited excellent photocatalytic and antibacterial activities.

AbstractRational designing of multicomponent selenide‐based composites such as Co9Se8/Ni3Se4/Cu2Se (CNCD) is synthesized through a simplistic hydrothermal method. Several standard characterization techniques are utilized to study the structural, morphological and elemental features of the obtained samples with varying selenide content. Both electrochemically and photocatalytic performance are amplified at an optimized selenide content denoted as CNCD‐0.5 due to its favourable characteristics and morphology. From the electrochemical measurements, the battery‐type performance of the CNCD‐0.5 is established from the well‐distinguished redox peaks. For practical utility, the assembled CNCD‐0.5 (+) // AC (−) device delivered an energy density of 35.97 Wh kg−1 at a power density of 1210.86 W kg−1 with a capacity retention of 91% for 5000 cycles of uninterrupted charge–discharge. Further, the photo‐Fenton‐based degradation experiments are assessed by demineralization of cationic RhodamineB (RhB) and anionic Tartrazine (Tz) dye using H2O2 with the minimal dosage of catalyst (0.3 g L−1). At an optimized concentration of H2O2, CNCD‐0.5 can degrade 97.14% of RhB (40 mg L−1) and 94.77% of Tz (40 mg L−1) for 120 min of visible‐light illumination. Such designing of multinary metal selenides‐based nanocomposites holds promising potential for multifunctional applications due to the synergistic advancement in the composite properties.

Published: August 2024

AbstractBismuth (Bi) has attracted widespread attention for sodium storage due to its high electronic/ionic conductivity, suitable reaction potential, and theoretical capacity (386 mAh g−1). However, Bi electrodes have a relatively high volumetric expansion ratio, which constrains their high capacity and affects the battery's cycle performance. Herein, a highly dispersed Bi atomic cluster is controllably prepared anchored on a porous TiO2 substrate through in situ segregation from Bi4Ti3O12 (TiO2/BiAC). The highly dispersed Bi clusters can serve as an “Ionic sponge” and accommodate more Na+ without causing excessive stress. Additionally, it aids in the decomposition of NaPF6, leading to the formation of a durable solid‐electrolyte interphase (SEI) layer rich in inorganic components. As expected, TiO2/BiAC exhibits excellent sodium storage performance in terms of cycling stability (346 mAh g−1 after 1000 cycles@ 1A g−1) and rate capability (231 mAh g−1 @ 100 A g−1). The pouch cell is further assembled and exhibits a specific capacity of 1.2 Ah after 200 cycles. This discovery presents a new method for developing efficient anode materials and is essential for steering the advancement of anode materials with fast charge–discharge capabilities.

AbstractBackgroundGiven the importance of the standardized letter of evaluation (SLOE) for application to emergency medicine (EM) residency, it is important that SLOE developers and authors understand how reviewers determine SLOE competitiveness. To inform SLOE design and authorship, the authors set out to build a novel theory to explain how faculty holistically interpret SLOE competitiveness.MethodsThe authors used constructivist grounded theory to explore how EM faculty determine SLOE competitiveness. They used purposive sampling to recruit EM faculty participants with at least 1 year of experience in scoring SLOEs. One author conducted hour‐long, semistructured interviews over Zoom between August 2023 and March 2024. Two authors iteratively coded the data to develop the initial codebook, organize codes into categories, and build connections to construct the resulting theory.ResultsThe authors interviewed 11 EM faculty from throughout the United States. Participants described a complex process to determine SLOE competitiveness. They began by contextualizing the SLOE to determine its trustworthiness and value before using various components of the SLOE to stratify and refine their understanding of competitiveness. Finally, when participants noted the inconsistency between different aspects of the SLOE, they used various methods to reconcile discordances and determine competitiveness.ConclusionsThis study illuminates the framework used by EM faculty to determine applicant competitiveness based on the SLOE and highlights several factors that SLOE authors should consider to ensure the accurate and efficient transfer of information.

AbstractBackgroundA retrospective cohort study was conducted to estimate associations between an ultrafine aluminum powder, McIntyre Powder (MP), and cardiovascular disease incidence in a cohort of mine workers from Ontario, Canada. Disease outcomes included ischemic heart disease (IHD), acute myocardial infarction (AMI), congestive heart failure (CHF), and strokes and transient ischemic attacks (STIA).MethodsUsing work history records from the Ontario Mining Master File (MMF) mine workers were followed for disease incidence in administrative health records. The analysis included 25,813 mine workers who were exposed to MP between 1943 and 1979 and followed for cardiovascular disease (CVD) diagnoses between 2006 and 2018. Cardiovascular disease cases were ascertained using physician, hospital, and ambulatory care records. Poisson regression models were used to estimate age and birth‐year adjusted incidence rate ratios (RR) and 95% confidence intervals (CI) for associations between MP exposure and CVD outcomes.ResultsEver‐exposure to MP was positively associated with modest increases in the incidence rate of IHD, AMI, and CHF, but not STIA, using both assessment approaches. Duration of self‐reported MP exposure was positively associated with monotonically increasing rates of IHD and AMI compared to never‐exposed miners, with the greatest association observed among miners with >20 years of exposure (for IHD: RR 1.24, 95% CI: 0.91–1.68; and for AMI: RR 1.52, 95% CI 1.01–2.28).ConclusionMine workers ever‐exposed to MP had modestly elevated rates of CVD. The rate of CVD diagnoses appeared to increase with longer duration of exposure when assessed by both self‐reported exposure and through historical records.

Published: August 2024

Key points
The study found a higher incidence of chronic rhinosinusitis (CRS) and recalcitrant CRS in cadaveric organ transplant recipients compared to those receiving living donor transplants. Recipients of cadaveric transplants were 1.32 times more likely to develop CRS and 1.68 times more likely to develop medically recalcitrant CRS.
Living kidney transplants significantly reduced the risk of developing CRS (OR = 0.12) and recalcitrant CRS (OR = 0.11), highlighting a potentially protective effect against these conditions. In contrast, cadaveric liver transplants were associated with an increased risk of CRS and medically recalcitrant CRS.
Kaplan–Meier survival analysis indicated a significant difference in time to CRS onset between cadaveric and living donor transplants. Median time to CRS onset was longer for living donor recipients (21.1 months) compared to cadaveric recipients (15.6 months). This study underscores the need for transplant teams and otolaryngologist to consider donor type during transplant follow‐up due to differing risks of CRS development.

AbstractPaleophysiology is an emergent discipline. Organismic (integrative) approaches seem more appropriate than studies focusing on the variation of specific features because traits are tightly related in actual organisms. Here, we used such an organismic approach (including lifestyle, thermometabolism, and hunting behavior) to understand the paleobiology of the lower Jurassic (Toarcian) thalattosuchian metriorhynchoid Pelagosaurus typus. First, we show that the lifestyle (aquatic, amphibious, terrestrial) has an effect on the femoral compactness profiles in amniotes. The profile of Pelagosaurus indicates that it was amphibious, with a foraging activity in shallow marine environments (as suggested by the presence of salt glands) and thermoregulatory basking behavior in land (as suggested by the presence of osteoderms with highly developed ornamentation). As for the thermometabolism, we show that the mass‐independent resting metabolic rate of Pelagosaurus is relatively high compared to the sample of extant ectothermic amniotes, but analysis of vascular canal diameter and inferences of red blood cell size refute the hypothesis suggesting incipient endothermy. Finally, the foraging behavior was inferred using two proxies. Pelagosaurus had a mass‐independent maximum metabolic rate and an aerobic scope higher than those measured in the almost motionless Iguana iguana, similar to those measured in the sit‐and‐wait predator Crocodylus porosus but lower than those quantified in the active hunter Varanus gouldii. These results suggest that Pelagosaurus may have had a hunting behavior involving a slow sustained swimming or a patient waiting in shallow waters, and may have caught preys like gharials, using fast sideways sweeping motions of the head.
