A state of the art review of hydroforming technology
Authors: Bell Colin , Corney Jonathan , Zuelli Nicola , Savings David 
Published: December 2019

AbstractHydroforming is a relatively new metal forming process with many advantages over traditional cold forming processes including the ability to create more complicated components with fewer operations. For certain geometries, hydroforming technology permits the creation of parts that are lighter weight, have stiffer properties, are cheaper to produce and can be manufactured from fewer blanks which produces less material waste. This paper provides a detailed survey of the hydroforming literature of both established and emerging processes in a single taxonomy. Recently reported innovations in hydroforming processes (which are incorporated in the taxonomy) are also detailed and classified in terms of “technology readiness level”. The paper concludes with a discussion on the future of hydroforming including the current state of the art techniques, the research directions, and the process advantages to make predictions about emerging hydroforming technologies.

Abstract
Background
Psychological distress and inappropriate or excessive weight gain are common in pregnancy and are associated with adverse maternal and offspring outcomes. Psychological well-being and weight status of women during pregnancy might be interrelated. We aimed to examine whether psychological distress during pregnancy is associated with gestational weight gain.

Method
In a population-based cohort of 3393 pregnant women, information about psychological distress, depressive and anxiety symptoms was assessed at 20 weeks of gestation using the Brief Symptom Inventory questionnaire. Weight was repeatedly measured during pregnancy and obtained by questionnaire before and after pregnancy. Linear regression and multinomial logistic regression models were used. Weight gain in the second half of pregnancy, total weight gain, and the risks of inadequate and excessive total weight gain were the main outcome measures.

Results
In total, 7.0% of all women experienced psychological distress. Overall psychological distress and anxiety were associated with lower weight gain in the second half of pregnancy (differences − 1.00 kg (95% confidence interval (CI) − 1.62, − 0.37) and − 0.68 kg (95% CI - 1.24, -0.11), respectively). These associations fully attenuated into non-significance after taking account for socio-demographic variables. Similar results were observed for total weight gain. Only women with anxiety symptoms had, independently of potential confounders, a lower risk of excessive weight gain (odds ratio (OR) 0.61 (95% CI 0.48, 0.91)).

Conclusions
In this large prospective cohort study, the observed associations of psychological distress with weight gain during pregnancy seem to be largely explained by common socio-demographic factors.

Abstract
Objective
Describe the two-phase validation process for a taxonomy of skills learned through mindfulness practice.

Methods
Phase I (development) utilized 11 subject matter experts (SMEs) over 5 months. Phase II (judgment) enrolled 60 international SMEs from 116 invited through snowball sampling. They were mostly white (80%) or Asian (15%) women (70%) with longstanding personal mindfulness practices (M = 20 years; SD = 9.6) and extensive mindfulness teaching experience (M = 11 years; SD = 6.7); 59% > 50 years; 88% had graduate degrees. SMEs rated relevance and clarity to calculate Individual Content Validity Indices (I-CVIs) for each category per tier and average CVIs (ave-CVIs) for entire tiers. Participation rate was 52% and 42 SMEs rated secondary tiers.

Results
I-CVIs ranged from 0.57 to 0.97, suggesting the removal of one category from the primary tier, leaving an ave-CVI for relevance of 0.92 (range 0.73–0.97). Clarity ratings for the primary tier (ave-CVI = 0.75; range of I-CVI = 0.52–0.88) necessitated exploration of the subcategories of Awareness (second tier; N = 42) to refine description (ave-CVI = 0.80 for clarity; range 0.64–0.93) while showing excellent content validity for both relevance and fit (ave-CVI = 0.95; range 0.88–1.0 for both).

Conclusions
The eMindful Mindfulness Classification Construct™ (eMCC™) is a validated, atheoretical taxonomy of skills learned through mindfulness practice, created to support development of more precise mindfulness-based interventions (MBIs) that target skill deficits associated with clinical conditions. Further research will validate subcategories, associate specific practices per category, and assess MBIs designed to target specific skills from the eMCC™.

AbstractObjectivesMindfulness training (MT) guidelines recommend that trainers have familiarity and knowledge of the training group as well as extensive MT expertise. Herein, a “train-the-trainer” (TTT) dissemination model was investigated for military service members whose access to MT is threatened by a scarcity of qualified trainers.MethodsUS Army Master Resilience Trainer-Performance Experts (PEs), who had extensive familiarity with soldiers but no prior MT experience, participated in an MT practicum, and then delivered a 4-week MT program (Mindfulness-Based Attention Training, MBAT) contextualized for military personnel. Soldiers (n = 180) undergoing intensive military field training over the study interval were recruited as participants. MBAT was delivered to soldiers by PEs (n = 89) or by a trainer with extensive MT experience (Mindfulness Expert; ME,n = 45) but no military familiarity. The remaining participants served as no-training controls (NTC,n = 46). Soldiers’ performance on sustained attention and working memory (WM) tasks was assessed before (week 0, T1) and after MBAT delivery (week 5, T2), and again 4 weeks later (week 10, T3).ResultsFor all participants, sustained attention and WM performance declined over the high-demand field training interval (p < 0.001). Yet, the PE group declined significantly less in attentional (p = 0.040) and WM (p < 0.001) performance relative to the other groups.ConclusionsThese results suggest that TTT delivery of short-form MT by context-familiar trainers may be an expeditious route by which to increase access to MT in the service of promoting cognitive resilience in high-demand groups.

Published: December 2019

AbstractThe prediction of contaminant transport in porous media is an important problem in order to prevent the pollution propagation in groundwater. The present model is developed by coupling two mesh-free approaches in order to overcome the restrictions of mesh-dependent methods. In this model, the ground water flow model is developed by analytic-element method and the contaminant transport model is developed by point collocation method in an unconfined aquifer. The model was developed and implemented by Python object-oriented programming language. A particle swarm optimization algorithm has been also utilized to calibrate the model. The model was applied for contamination transport in Astaneh-Kuchesfahan groundwater in north of Iran. Comparison of the model results with the observed data represents a reasonable agreement and capability of the present model in contaminant transport modeling. Moreover, the calculated value for coefficient of determination (R2 = 0.89) indicates that the calibrated parameters are acceptable.

Published: December 2019

AbstractAqueous solubility of an active pharmaceutical ingredient (API) is a determining factor that has a direct impact on formulation strategies and overall bioavailability. Fabrication of nanoemulsions of poorly soluble drugs is one of the widely utilized approaches to overcome this problem. However, thermodynamic instability and tedious manufacturing processes of nanoemulsions limit their clinical translation. Therefore, this study was focused on circumventing the abovementioned hurdles by utilizing the polymer as an oil phase, instead of conventional oils. The nanoemulsion was prepared via a facile low-energy nanoprecipitation method using renewable poly(δ-decalactone) (PDL), as an oil phase and Pluronic F-68 as surfactant. The prepared nanoemulsions were characterized in terms of size, drug encapsulation efficiency, stability, and toxicity. Five different hydrophobic drugs were utilized to evaluate the drug delivery capability of the PDL nanoemulsion. The prepared nanoemulsions with sizes less than 200 nm were capable to enhance the aqueous solubility of the drugs by 3 to 10 times compared with the well-established Pluronic F-68 micelles. No phase separation or significant changes in size and drug content was observed with PDL nanoemulsions after high-speed centrifugation and 3 months of storage at two different temperatures (20 °C and 50 °C). PDL nanoemulsions were found to be non-heamolytic up to concentrations of 1 mg/mL, and the cell cytotoxicity studies on MDA-MB-231 and MEF cells suggest a concentration and time-dependent toxicity, where the PDL polymer itself induced no cytotoxicity. The results from this study clearly indicate that the PDL polymer has a tremendous potential to be utilized as an oil phase to prepare stable nanoemulsions via a facile methodology, ultimately favouring clinical translations.
Removal of sulfur contaminants from biogas to enable direct catalytic methanation
Authors: Dannesboe Christian , Hansen John Bøgild , Johannsen Ib 
Published: December 2019

AbstractIn the near future, renewable energy sources will replace fossil energy. To allow full carbon utilization of renewable biomass, we have demonstrated a possible integration between a biogas reactor, an electrolysis unit, and a catalytic methanation reactor. Stringent removal of all sulfur contaminants in raw biogas is required to enable this integration. We demonstrate how existing bulk sulfur removal solutions, like a biotrickling filter loaded with Acidithiobacillus thiooxidans and impregnated activated carbon, are unable to meet this requirement. Only the main sulfur contaminant hydrogen sulfide (H2S) can effectively be removed. Contaminants carbon disulfide (CS2), dimethyl sulfide (DMS), and carbonyl sulfide (COS) will leak through the carbon filter, long before hydrogen sulfide can be detected. Utilization of surplus oxygen from the combined system is proven problem free and allows sulfur removal without introducing contaminants. Provided that a recommended sulfur guard is included, the proposed design is ready for full-scale implementation.

Published: December 2019

Abstract
Introduction
Release of the 2015 European Society of Cardiology (ESC)/European Respiratory Society (ERS) guidelines put increased emphasis on using combination therapy, either as upfront or sequential therapy among patients with pulmonary arterial hypertension (PAH). However, with these recommendations and the therapy advances made in the last several years, little is known on the real-world treatment patterns among patients with PAH, particularly before and after publication of the 2015 ESC/ERS guidelines.

Methods
This was a retrospective study of adult commercial and Medicare Advantage with Part D (MAPD) enrollees with at least one claim for a PAH-related medication from January 01, 2012 to March 31, 2017, at least one medical claim with a pulmonary hypertension diagnosis, and continuous health plan enrollment at least 6 months prior to and at least 12 months following the date of the first pharmacy claim for PAH-related therapy (index date). Patients were divided into cohorts based on prescription of monotherapy or combination therapy and index date category (2012–2013, January 2014–July 2015, and August 2015–March 2017).

Results
Out of 1878 patients, 90.8% initiated with monotherapy and 9.2% initiated with combination therapy. The percentage of patients with index combination therapy increased from 5.7% in 2012–2013 to 13.0% in August 2015–March 2017. Patients with index combination therapy had better persistence (11.6 months versus 10.3 months) and adherence (0.95 versus 0.85). Overall, the discontinuation rate was 40% and was higher in monotherapy versus combination therapy patients (42.8% versus 12.2%). Approximately 30.2% of patients had a second regimen, of which 50% were combination regimens. The time to combination therapy initiation decreased from 10.5 months in 2012–2013 to 3.4 months in August 2015–March 2017.

Conclusions
The majority of patients initiated monotherapy treatment for PAH, most often a phosphodiesterase 5 inhibitor (PDE5i). Patients with upfront combination therapy increased following publication of the 2015 ESC/ERS guidelines, indicating that physicians responded to the guideline’s option of prescribing upfront combination therapy.
When Less Is More: On the Use of Historical Yield Data with Application to Rating Area Crop Insurance Contracts
Authors: Liu Yong , Ker Alan P. 
Published: December 2019

AbstractCrop insurance is the cornerstone program of domestic farm policy in most developed countries. Although most countries’ rating methodology corrects for time-varying movements in the first two moments, it is unclear whether using the entire yield series remains appropriate. We use distributional tests and an out-of-sample retain-cede rating game to answer whether governments/insurers should historically trim yields in estimating their premium rates. Despite small sample sizes and the need to estimate tail probabilities, the historical data appear to be sufficiently different such that trimming is justified.

AbstractThis study provides insights about the diversity, prevalence and distribution of alpine wild galliformes gastrointestinal parasite community, trying to fill a gap in the scientific information currently available in scientific literature. The analysis included three host species: 77 rock partridge (Alectoris graeca saxatilis), 83 black grouse (Tetrao tetrix tetrix) and 26 rock ptarmigan (Lagopus muta helveticus) shot during the hunting seasons 2008–2015. Parasites isolated wereAscaridia compar, Capillaria caudinflataand cestodes. The rock ptarmigan was free from gastrointestinal parasites, whereas the most prevalent helminth (37%) wasA. comparin both black grouse and rock partridge.C. caudinflataoccurrence was significantly higher in black grouse (prevalence = 10%, mean abundance = 0.6 parasites/sampled animal) than in rock partridge (prevalence = 1.20%, mean abundance = 0.01 parasites/sampled animal). Significant differences were detected among hunting districts.A. comparwas found with a significant higher degree of infestation in the hunting districts in the northern part of the study area whereas cestodes abundance was higher in Lanzo Valley. Quantitative analysis of risk factors was carried out using a generalized linear model (GLM) only on the most common parasite (A. compar). Latitude was the only factors associated with infestation risk (OR = 52.4). This study provides information on the composition and variability of the parasite community in the alpine Galliformes species.
Diagnostik von ICT Literacy: Messen Multiple-Choice-Aufgaben und simulationsbasierte Aufgaben vergleichbare Konstrukte?
Authors: Senkbeil Martin , Ihme Jan Marten 
Published: December 2019

Zusammenfassung. ICT Literacy legt eine performanzbasierte Erfassung mit simulierten und interaktiven Testaufgaben nahe. Der vorliegende Beitrag untersucht, ob mit Multiple-Choice (MC)-Aufgaben ein vergleichbares Konstrukt wie mit Simulationsaufgaben erfasst wird. Hierfür wurden die Testergebnisse zweier Instrumente aus aktuellen Large-Scale-Studien gegenübergestellt, die an N = 2 075 Jugendlichen erhoben wurden: der auf MC-Aufgaben basierende ICT Literacy-Test für Klasse 9 des Nationalen Bildungspanels (National Educational Panel Study, NEPS) und der simulationsbasierte Kompetenztest der internationalen Schulleistungsstudie ICILS 2013 (International Computer and Information Literacy Study). Die Analysen unterstützen die Gültigkeit der Konstruktinterpretation des MC-basierten Tests in NEPS. Im Sinne der konvergenten Evidenz korrelieren die MC-Aufgaben substanziell mit den computer- und simulationsbasierten Aufgaben in ICILS 2013 (.68 ≤ r ≤ .90). Weiterhin ergeben sich positive und für beide Tests vergleichbar hohe Korrelationen mit ICT-bezogenen Schülermerkmalen (z. B. Selbstwirksamkeit). Weiterführende Analysen zum Zusammenhang mit allgemeinen kognitiven Fähigkeiten zeigen zudem, dass ICT Literacy und kognitive Grundfähigkeiten distinkte Faktoren repräsentieren.
Sources, Transport, and Transformation of Dissolved Organic Matter in a Large River System: Illustrated by the Changjiang River, China

Published: December 2019

AbstractThe sources, transport, and transformation of terrestrial dissolved organic matter (DOM) in large river systems are of great interest due to their importance in the regional and global carbon cycles. However, knowledge of these factors is limited, especially for different DOM compositions coupling with hydrodynamics at the basin scale. To investigate the dynamics of different DOM compositions in a large river system, we characterized the dissolved organic carbon (DOC), chromophoric DOM (CDOM), and dissolved lignin at both moderate (September–October 2009) and high (August 2012) discharges in the Changjiang River basin. We found that extensive soil erosion resulted in the increased DOC concentration in the middle to lower reaches in 2012. In 2009, the transformation of DOM was dominated by flocculation and photo degradation due to the low flow velocity and depressed particle suspension. In 2012, the degradation of CDOM and dissolved lignin was coupled and dominated by microbial degradation and photo degradation. In 2012, CDOM (absorbance and fluorescence) and dissolved lignin concentrations were positively correlated, demonstrating the potential of using CDOM to quantitatively estimate dissolved lignin. Mass balance estimations of the DOM fluxes further confirmed that 17.0% (6.1%) of DOC, 24.2% (32.3%) of dissolved lignin, and 14.5% (0.8%) of CDOM were degraded at high (moderate) discharge. This study reveals contrasting transformation processes of DOM compositions with different sources and reactivities along the Changjiang River under different hydrological conditions, and it provides new insights into the linkage between the chemical and optical properties of DOM in large river systems.
Global Carbon Sequestration Is Highly Sensitive to Model‐Based Formulations of Nitrogen Fixation

Published: December 2019

AbstractBiological nitrogen fixation (BNF) is the largest nitrogen (N) input pathway in natural terrestrial ecosystems at present, fueling the drawdown of atmospheric CO2 in vegetation and soil on decadal to century time scales. Here, we use a global land‐surface model (CABLE) with three different approaches for estimating the responses of BNF to CO2, climate, and N deposition through Year 2100, particularly the linear versus nonlinear dependence of BNF on C investment and the temperature dependence of BNF. From 1900 to 2100, the cumulative rise in BNF varied from 1.6 to 3.0 Pg N, translating to an increase in terrestrial carbon (C) storage between 33 and 68 Pg C. This range reflects the different approaches used to model BNF (i.e., C‐limited vs. resource optimization approaches), indicating major uncertainties in C‐climate‐N interactions in Earth system model forecasts. The differences among different approaches were most significant at high or low latitudes. At high latitudes, accounting for temperature dependence of BNF resulted in 53% and 79% additional BNF increases and 14% and 21% additional land C accumulation in evergreen needle leaf forest and tundra, respectively, from 1901 to 2100. At low latitudes, resource optimization approaches using linear dependence of BNF on C investment estimated more rapid increase in BNF and therefore greater C accumulation than the C‐limited approach using nonlinear dependence. The difference in the estimated additional C accumulation due to varying BNF was as much as 24% for deciduous broadleaf forest. Our findings highlight the need for more field measurements of BNF, particularly at high latitudes to better constrain the projected BNF under future conditions, and also the fundamental importance of BNF in determining the pattern, response, and magnitude of terrestrial C accumulation through 2100.

Published: December 2019

AbstractThe utility of a high‐resolution snow‐hydrologic model to derive climatological indices that describe the variability in radial growth of four conifer species in two Sierra Nevada sites is presented herein. Nine annual indices associated with radial growth were developed to represent the winter dormancy, characteristics of the snowpack and soil water content, and the duration of the seasons. Site chronologies of earlywood (EW) and latewood (LW) ring widths were developed for mountain hemlock (Tsuga mertensiana), red fir (Abies magnifica), white fir (Abies concolor), and ponderosa pine (Pinus ponderosa) at two sites on leeward and windward slopes. The signal strength for annual climatological indices derived from model output was tested with correlation and regression, in combination with principal components analysis. Results show significant snow‐related climate signal in the tree‐ring data, with substantial differences between species and between EW and LW. Dependence on previous year's snow and soil moisture (a lagged response) were found for EW of hemlock and red fir. The primary EW‐LW signal contrast for those species is a shift toward dependence on current‐year moisture conditions for LW, especially for red fir. Lagged climate response was less evident for white fir and ponderosa pine. Regression of tree‐ring series on principal components of climatological indices showed a stronger average signal in EW (R2 = 0.48) than in LW (R2 = 0.35). Differences in tree‐ring hydrologic signal at the two sites are attributed to microclimate and contrasts in snow regime. Results attest to the hydrologic model usefulness for investigating temporal relationships between tree rings and local climate.
