Early Holocene sea level in the Canadian Beaufort Sea constrained by radiocarbon dates from a deep borehole in the Mackenzie Trough, Arctic Canada

Field: Earth and Planetary Sciences (Physical Sciences)

Deglacial and Holocene relative sea level ( RSL ) in the Canadian Beaufort Sea was influenced by the timing and extent of glacial ice in the Mackenzie River corridor and adjacent coastal plains. Considerable evidence indicates extensive ice cover in this region of northwestern Canada during the Late Wisconsinan. However, no absolute ages exist to constrain maximum RSL lowering before the late Holocene (4.2–0 ka). In 1984, the Geological Survey of Canada drilled an 81.5‐m‐deep borehole in the western Mackenzie Trough at 45 m water depth ( MTW 01). The lower 52.5 m of the borehole was interpreted as a deltaic progradational sequence deposited during a period of rising sea level. The upper 29 m was described as foraminifer‐bearing marine sediments deposited after transgression of the site, when RSL rose above ~−74 m. Here, we present radiocarbon measurements from MTW 01, acquired from benthic foraminifera, mollusc fragments and particulate organic carbon in the >63 μm fraction ( POC >63 μm ) in an attempt to constrain the chronology of sediments within this borehole and date the timing of transgression. The deepest carbonate macrofossil was acquired from 8 m above the transgressive surface (equivalent to 21 m b.s.l.), where mollusc fragments returned a date of 9400 +180–260 cal. a BP (2σ). This provides the oldest constraint on Holocene sea‐level lowering in the region, and implies that transgression at this site occurred prior to the early Holocene. Ages obtained from the lower 52.5 m of the borehole are limited to POC >63 μm samples. These indicate that progradational sediments were deposited rapidly after 24 820 +390–380 cal. a BP (2σ). Due to the incorporation of older reworked organic matter, the actual age of progradation is likely to be younger, occurring after Late Wisconsinan glacial ice retreated from the coast.
Morphological variation among Sticherus flabellatus (Gleicheniaceae) populations of the Sydney region

Field: Agricultural and Biological Sciences (Life Sciences)

The morphological variation among 14 natural populations of the horticulturally important species, Sticherus flabellatus was assessed by using a set of quantitative whole-plant (sporophyte) and frond characters, and photosynthetic pigments. Of the 14 populations, 11 were located within or on the periphery of the Sydney region, and three populations were outside this region (two north, one south) to represent most of the species’ New South Wales range. Univariate and multivariate statistical analyses revealed significant differentiation of all 14 populations. Discrimination of the populations was based on a subset of whole-plant and frond characters, with photosynthetic pigment ratios exhibiting the greatest variation between populations. These traits exhibited sufficient variation to be useful as markers for population identification and discrimination. The distribution of morphological variation revealed two broad ecotypes; closed forest and open forest. These local adaptations could not be partitioned into geographic regions. The distribution of variation in this species has implications for the horticultural industry and the conservation of natural populations.
Between the external and internal world. Globalization and the discomfort of emotions

Field: Social Sciences (Social Sciences)

This paper calls for the launch of a reflection on the relationships and reciprocal interactions between the ‘external world’ and the ‘internal world’ based on how, socially and culturally, the reality of these two spaces are configured in the era of late-capitalist globalization. A globalization that is marked by the intensification of the processes of the financialisation of the economy, of the decomposition and division of labour, and of the de-localisation and de-territorialisation of production, which results in an increasingly marked lack of distinction among the \nmany spheres of existence in our subjectivities. \nThis work traces a path that moves from the solicitations offered by the \ncontemporary debate in geography - from David Harvey’s fundamental body of work to Doreen Massey’s relational approach - to then focus on the contributions of Paolo Virno, and of Toni Negri and Michael Hardt. The attempt to comprehend how and if the fine border between the external world and the internal world has today been transformed and constituted leads to the connection of a critical reading of the processes of the accumulation of capital in the contemporary world to the important psychoanalytic contributions of René Kaes, which are dedicated to the analysis of changes in subjective psychic formations. If the internal world (of emotions and the unconscious) appeared to be more differentiated in the diverse systems of cultural and ethical values before the ‘crisis of modernity’, at the time of late-capitalism the inner discomfort appears to grow indistinctively, as reflected in the symbolic and immaterial universe of communication that colonises our lives and characterises the present condition of postmodernity.
Chair-side surface treatment method for inducing hydrophilicity in titanium dental implant

Field: Dentistry (Health Sciences)

Titanium (Ti) has been widely used for dental implant due to great biocompatibility and bonding ability against natural alveolar bone. A lot of titanium surface modification has been introduced in dentistry and, among them, methods to introduce micro/nano-roughened surface were considered as clinically approved strategy for accelerating osseointegration of Ti dental implant. To have synergetic effect with topography oriented favors in cell attachment, chair-side surface treatment with reproducibility of micro/nano-topography is introduced as next strategy to further enhance cellular functionalities. Extensive research has been investigated to study the potential of micro/nano-topography preserved chair-side surface treatment for Ti dental implant. This review will discuss ultraviolet, low level of laser therapy and non-thermal atmospheric pressure plasma on Ti dental implant with micro/nano-topography as next generation of surface treatment due to its abilities to induce super-hydrophilicity or biofunctionality without change of topographical cues.
Effectiveness Of Medication Reviews In Identification And Management Of Medication Related Problems By Clinical Pharmacist

Field: Health Professions (Health Sciences)

Medication related problems (MRPs) are any preventable events that lead to inappropriate medication use or patient harm. Clinical pharmacist plays a key role in various clinical activities of hospital and contributes to improve the quality of medication use and patient safety with an aim to provide better patient outcome. Hence our aim in this study is to identify, classify and develop management strategy of various MRPs in a tertiary care teaching hospital and report them to concerned doctors to modify the drug therapy accordingly. Out of total collected cases; prescribing errors (21%) and adverse drug reaction (ADR) (35%) were most common, followed by drug duplication (11%), improper drug selection (8%), untreated indication (7%), double dosing (6%), wrong dose (5%) were frequently repeated drug related issues. Other MRPs were inappropriate dose, omission error, drug without indication and drug insufficiency with very minimal appearance which also satisfy the PCNE categorization of drug related problems. We found that Anticonvulsants and Antibiotics were frequently identified prescription medicine to develop MRPs.. Cerebrovascular accidents and Epilepsy were mostly involved in disease where MRPs were seen frequently. Standard management guidelines were also described to the doctors for individual MRP cases. Certain MRPs were frequently appearing and clinical pharmacists should be alert enough to address them with proper management strategy. Our study highlights the significant role of clinical pharmacist’s intervention in identification of MRPs, which generally remain unidentified unless harm occurs. This study also shows a new avenue of drug therapy optimization by providing proper medication information to overcome identified MRP issues to enhance patient safety and care. Our role was highly accepted and appreciated by various doctors.

Storytelling from the Colonial Margins of the Academy: Urban Mixed Ancestry Indigenous experience in and around social work classrooms of T’karonto

Field: Social Sciences (Social Sciences)

This is an Indigenous research journey. This journey focuses on the stories of the lived experiences of Urban Mixed Ancestry Indigenous students in T’karonto while attending post-secondary social work classrooms where they received Indigenous focused or indigenized curricula. Using a Mohawk approach to research (that includes traditional teachings from an Elder and a storytelling approach), this paper explores the impact this curriculum has on Urban Mixed Ancestry Indigenous social work students as they express their stories of attending university and their social work program in T’karonto - through paintings. It also explores the colonial, societal and institutional factors that cause Urban Mixed Ancestry Indigenous students to question their Indigenous identity within post-secondary social work classrooms. These stories provide knowledge on how to move forward in a good way when implementing Indigenized curricula within non-Indigenous and settler-colonial classrooms.

Computation of generalized stress intensity factors for bonded elastic structures

Field: Mathematics (Physical Sciences)

We consider coupled structures consisting of two different linear elastic materials bonded along an interface. The material discontinuities combined with geometrical peculiarities of the outer boundary lead to unbounded stresses. The mathematical analysis of the singular behaviour of the elastic fields, especially near points where the interface meets the outer boundary, can be carried out by means of asymptotic expansions with respect to the distance from the geometrical and structural singularities. The coefficients in the asymptotics which are called generalized stress intensity factors play an important role in classical fracture criteria. In this paper we present several formulas for the generalized stress intensity factors for coupled elastic structures. The formulas have the form of scalar products or convolution integrals of the given data or the unknown displacement field and the so-called weight functions, similar to Maz'ya/Plamenevsky functionals introduced in [13, 14] for elliptic boundary value problems. The weight functions are non-energetic elastic fields, which admit a decomposition into a known singular part and a more regular one, which is computed by boundary element domain decomposition methods.

Weekly versus every-three-weeks platinum-based chemoradiation regimens for head and neck cancer

Field: Medicine (Health Sciences)

Background The majority of chemoradiation (CRT) trials for locally advanced head and neck squamous cell carcinoma (HNSCC) have relied on platinum-based chemotherapy regimens administered every-3-weeks. However, given the increased utilization of weekly platinum regimens, it remains unclear how different chemotherapy schedules compare regarding efficacy and toxicity. Methods We retrospectively identified 212 patients with HNSCC who were treated at a single academic medical center with concurrent platinum-based CRT given weekly ( N = 68) or every-three-weeks ( N = 144). JMP version 10 (SAS Institute) was used for statistical analysis. Discrete variables were compared with the chi-square test and differences in the medians were assessed using the Wilcoxon test. Survival curves were constructed using the Kaplan-Meier method and significance was assessed using the log rank test. For univariate analysis and multivariate analysis, we used Cox proportional hazard or logistic regression models to compare differences in survival or differences in categorical variables, respectively. Results Patients receiving weekly platinum regimens were more likely to be older (median age 61.4 vs. 55.5 y; P < .001), have high or very high Charlson comorbidity index (45.6% vs. 27.8%; P = .01), and receive carboplatin-based chemotherapy (6.3% vs. 76.5%; P < .001). Weekly and every-3-week platinum regimens had similar locoregional control (HR 1.10; 95% CI 0.63–1.88; P = .72), progression-free survival (HR 1.13; 95% CI 0.75–1.69; P = .55), and overall survival (HR 1.11; 95% CI 0.64–1.86; P = .71). Every-3-weeks platinum regimens were associated with increased days of hospitalization (median: 3 days vs. 0 days; P = .03) and acute kidney injury (AKI) during radiotherapy (50.0% vs. 22.1%; P < .001). On multivariate analysis, AKI was significantly associated with every-3-weeks regimens (OR: 24.38; 95% CI 3.00–198.03; P = .003) and high comorbidity scores (OR: 2.74; 95% CI 2.15–5.99; P = .01). Conclusions Our results suggest that every-3-weeks and weekly platinum-containing CRT regimens have similar disease control but weekly platinum regimens are associated with less acute toxicity.
Mitigating gaseous losses of nitrogen from pasture soil with urease and nitrification inhibitors

Field: Agricultural and Biological Sciences (Life Sciences)

Addition of nitrogen (N) to soil from various sources (i.e., animal excreta, farm effluents, synthetic fertilizers, crop residues and biological fixation), results in release of gaseous N such as nitrous oxide (N2O) and ammonia (NH3). In grazed pasture soils, mitigation options need to focus on limiting the loss of N directly from animal excreta, farm effluents and synthetic fertilizers, and the indirect loss caused by leaching and (NH3) volatilization. One such approach is the use of urease (UI) and nitrification inhibitors (NI). Urease inhibitors retard the hydrolysis of urea N in urea-based fertilizers and urine, thereby decreasing the concentration of ammonium (NH4+) in soil solution and the subsequent NH3 volatilization. Whereas NIs specifically retard the oxidation of NH4+ to nitrite (NO2-), thereby decreasing the concentration of nitrate (NO3-) and the subsequent leaching and denitrification. However, strategies to reduce emission of one gas may affect the emission of the other. Therefore, abatement strategies require simultaneous measurements of NH3 and N2O emissions. In a joint project, Massey University and Landcare Research are attempting various approaches for the abatement of gaseous N emissions. This paper reports the impacts of UI (N-(n-butyl) thiophosphoric triamide; Agrotain) and NI (Dicyandiamide; DCD) on the emissions of NH3 and N2O from urine and urea applied to intact pasture soil cores. Our results indicate that the addition of UI Agrotain delayed the onset and reduced NH3 emissions by 27% and 23% from urea and urine, respectively. Urease inhibitor also reduced N2O emissions significantly from urine. DCD applied at 25 kg/ha to urea in the presence and absence of UI Agrotain reduced the amount of N2O emissions by 68% and 74% respectively. However, DCD did not cause any significant change in NH3 emissions. Our results suggest that there is a considerable scope for reduction of N2O emissions by applying (DCD) both in the presence and absence of Agrotain.
Low molybdenum status of serpentine soils of western North America

Field: Environmental Science (Physical Sciences)

Surface samples of 33 serpentine soils and 22 non-serpentine soils from a wide range of locations In the North Coast Range of California, in southwestern Oregon and in western Washington State, were analysed for availablemolybdenum (Mo) using the Mulder Aspergillus niger assay, and about 20 of these soils were tested by the Grigg oxalic acid extraction method. Most of the soils were neutral or slightly alkaline. Among the serpentine soils, 27 tested deficient' or very deficient' in available Mo, and only six were in the slightly deficient' or not deficient' categories. Among the non-serpentine soils, five were deficient', 11 were slightly deficient', and six were not deficient'. Since the analyses were made on the < 1 mm fraction, the gravelly/stony nature especially of the serpentine soils would make the available Mo levels in rhizospheres even lower. Agreement was good between results of the Mulder and Grigg methods of assay. Recovery from visible Mo-deficiency symptoms in lettuce and tomato plants grown on two of the serpentine soils was obtained with Mo fertilization. Analyses for total Mo in a few of the soils did not show exceptionally low values, suggesting that the low available Mo status of the serpentine soils is probably due to adsorption or fixation of this element, and possibly also due to leaching of available forms of Mo.
Hospital-acquired conditions: predictors and implications for outcomes following spine tumor resection

Field: Medicine (Health Sciences)

OBJECTIVE Hospital-acquired conditions (HACs) significantly compromise patient safety, and have been identified by the Centers for Medicare and Medicaid Services as events that will be associated with penalties for surgeons. The mitigation of HACs must be an important consideration during the postoperative management of patients undergoing spine tumor resection. The purpose of this study was to identify the risk factors for HACs and to characterize the relationship between HACs and other postoperative adverse events following spine tumor resection. METHODS The 2008–2014 American College of Surgeons’ National Surgical Quality Improvement Program database was used to identify adult patients undergoing the resection of intramedullary, intradural extramedullary, and extradural spine lesions via current procedural terminology and ICD-9 codes. Demographic, comorbidity, and operative variables were evaluated via bivariate statistics before being incorporated into a multivariable logistic regression model to identify the independent risk factors for HACs. Associations between HACs and other postoperative events, including death, readmission, prolonged length of stay, and various complications were determined through multivariable analysis while controlling for other significant variables. The c-statistic was computed to evaluate the predictive capacity of the regression models. RESULTS Of the 2170 patients included in the study, 195 (9.0%) developed an HAC. Only 2 perioperative variables, functional dependency and high body mass index, were risk factors for developing HACs (area under the curve = 0.654). Hospital-acquired conditions were independent predictors of all examined outcomes and complications, including death (OR 2.26, 95% CI 1.24–4.11, p = 0.007), prolonged length of stay (OR 2.74, 95% CI 1.98–3.80, p < 0.001), and readmission (OR 9.16, 95% CI 6.27–13.37, p < 0.001). The areas under the curve for these models ranged from 0.750 to 0.917. CONCLUSIONS The comorbidities assessed in this study were not strongly predictive of HACs. Other variables, including hospital-associated factors, may play a role in the development of these conditions. The presence of an HAC was found to be an independent risk factor for a variety of adverse events. These findings highlight the need for continued development of evidence-based protocols designed to reduce the incidence and severity of HACs.
