Enhanced Rainfall‐Induced Shallow Landslide Activity Following Seismic Disturbance—From Triggering to Healing

Evidence suggests that following earthquakes, landslide activity, and susceptibility remain elevated for months to years after cessation of shaking. In landslides constrained within the soil mantle, enhanced post‐seismic activity may be attributed to persistence of progressive failure surface development that results in delayed triggering. With subsequent post‐seismic hydrologic disturbance, a commensurate decay in activity over time reflects evacuation of damaged hillslope materials and mechanical healing of colluvial media and vegetation recovery. In this study, we propose a hydromechanical model for representing the interplay of these processes including trends in timing and magnitude of post‐seismic shallow landslide activity. The hydromechanical model considers seismic or hydrologic disturbances as drivers for failure surface development in the soil mantle over a hillslope with commensurate weakening through accumulation of internal compression, shear softening, and loss of root strength. In the absence of well‐instrumented post‐seismic landslide measurement of evolving stress conditions and deformation, predictions were made against a unique field case study where hydrologically induced hillslope failure kinematics and internal compression were measured. The model accounts for seismic disturbances, demonstrating that certain peak ground accelerations directly reduce subsequent rainfall‐induced landslide‐triggering thresholds relative to undisturbed hillslopes. The model framework can be used to describe progressive, post‐seismic landslide activity, demonstrating that consideration of root or soil healing may suppress subsequent landslide triggering and contribute toward recovery to pre‐seismic disturbance levels of strength. Factors such as shear softening, vegetation, and healing are explored in the context of the temporal evolution of landslide rates after a seismic event. The results of this paper show mechanistically how (1) progressive development or cessation of a failure surface in active, post‐seismic landslides may describe elevated post‐seismic landslide rates and (2) that hillslope healing plays a modest role in the magnitude and timescale of attenuated landslide activity.
“I’ve had a magical journey”: understanding how international sports coaches learn through cross-sport boundary encounters

ABSTRACT Recent approaches to facilitating coach development place considerable emphasis on social interaction aimed at enhancing participants’ learning through collaboration and discussion. This investigation examined the usefulness of utilising the Landscapes of Practice (LoP) framework to better understand such “social” learning, specifically focussing on boundary interactions experienced by international coaches. Having recently undertaken a cross-sport development programme, 14 coaches from 11 sports were interviewed and a thematic structure was subsequently established featuring four categories: (a) confidence, openness and authenticity, (b) sense making, (c) reflection and mentoring and (d) reconceptualising and reframing. This investigation found strong support for the usefulness of the LoP framework. Furthermore, knowledgeability and boundary interactions were insightful concepts to better understand how coaches learnt through interactions within, and beyond, the programme. For example, cross-sport interactions enabled some coaches to learn more effectively because they felt less encumbered by peers’ judgements when compared to other environments.
Thermal and Spectral Dielectric Properties of Polypyrrole/Polymethylmethacrylate Composites

ABSTRACT Thermal properties of polypyrrole/polymethylmethacrylate (PPy/PMMA) composites were analyzed by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). A decrease in the glass transition temperatures with PPy concentration reveals the increase of segmental motion. The dielectric properties of these composites were studied for several weight concentrations of PPy in the frequency range between 500 Hz and 0.2 MHz, over the temperature range 23–110°C. Jonscher's phenomenological model has been used for modeling the dielectric response of the composite materials. This study shows that the results obtained for the dielectric response are in good agreement with the results of TGA and DSC measurements.
Thyroid lobectomy in patients with differentiated thyroid cancer: an analysis of the clinical outcomes in a nationwide multicenter study.

Background Total thyroidectomy is the standard initial surgery for differentiated thyroid carcinoma (DTC), but the extent of the thyroidectomy remains controversial. Thyroid lobectomy (TL) has been widely used in eastern countries; however, its use has not been generalized in western countries, including Spain. Our aims were to analyse the clinical outcome of a multicentre nation-wide cohort of DTC patients treated by TL and to assess the proportion of patients who required completion of the thyroidectomy and who presented disease recurrence. Methods We retrospectively analyzed patients who underwent TL for DTC and were followed-up for ≥12 months. We collected demographic, clinical, and histopathological data. Dynamic risk stratification (DRS) was performed at 12 months and at last visit. Results One hundred and sixty-four patients (128 women, mean age 50.8 years, median follow-up 45.4 months) from 9 hospitals were included. There were 158 cases of papillary and 6 of follicular thyroid carcinoma (FTC). Remission of the disease (excellent response) was shown in 71.6% of the patients at 12 months and in 74.4% at the end of follow-up. At that time, there were 34 patients (20.7%) with indeterminate response, 6 (3.7%) with biochemical incomplete response, and 2 (1.2%) with structural incomplete response. Completion of the thyroidectomy was necessary in 8 patients (4.9%), but only 3 of them (1.8%) had disease recurrence. Conclusions These results, obtained in real clinical practice, suggest that TL is a safe operative option for selected patients with DTC and that the intensity of the treatment must be tailored according to the presurgical tumor-associated risk, in line with a personalized medicine.
A Deep-Learning-Based Bearing Fault Diagnosis Using Defect Signature Wavelet Image Visualization

A new method is established to construct the 2-D fault diagnosis representation of multiple bearing defects from 1-D acoustic emission signals. This technique starts by applying envelope analysis to extract the envelope signal. A novel strategy is propounded for the deployment of the continuous wavelet transform with damage frequency band information to generate the defect signature wavelet image (DSWI), which describes the acoustic emission signal in time-frequency-domain, reduces the nonstationary effect in the signal, shows discriminate pattern visualization for different types of faults, and associates with the defect signature of bearing faults. Using the resultant DSWI, the deep convolution neural network (DCNN) architecture is designed to identify the fault in the bearing. To evaluate the proposed algorithm, the performance of this technique is scrutinized by a series of experimental tests acquired from a self-designed testbed and corresponding to different bearing conditions. The performance from the experimental dataset demonstrates that the suggested methodology outperforms conventional approaches in terms of classification accuracy. The result of combining the DCNN with DSWI input yields an accuracy of 98.79% for classifying multiple bearing defects.

Cooperation and coordination in green supply chain with R&D uncertainty

Abstract Considering the uncertainty of environmental R&D, we investigate a two-echelon supply chain consisting of a manufacturer who invests in green manufacturing to generate a probability of R&D success and a retailer who exerts green marketing to disclose information on the successful R&D outcome to consumers. We explore cooperation issues in green operations by analysing two modes: Decentralized mode where the two firms do not cooperate in green operations, and Cartelization mode where they cooperate as an integrated system to set their individual green decision. We find Cartelization mode increases the profitability for the whole supply chain and the manufacturer but not the retailer. Compared with Decentralized mode, the green supply chain in Cartelization mode cannot be Pareto-improved unless the manufacturer efficiently motivates the retailer to cooperate. Furthermore, we discuss coordination issues under these two modes and find the revenue-sharing contract has more flexibility when coordinating the cartelized supply chain.
Intramolecular electronic relaxation and photoisomerization processes in the isolated azabenzene molecules pyridine, pyrazine and pyrimidine

For the three azabenzenes pyridine, pyrazine and pyrimidine, quantum yields for fluorescence and intersystem crossing have been measured in the vapour phase as a function of the excitation energy, ranging from the zero-point level of S1(n, π*) to the higher vibrational levels of S2(π, π*). The picosecond fluorescence lifetimes have also been measured by exciting the molecules at various wavelengths. For all three azabenzenes a particularly fast non-radiative decay channel has been found. The appearance of this new decay channel has also been demonstrated by direct measurement of the picosecond lifetime. In the lower excitation-energy region of the S1â†�S0 transition the intersystem-crossing process is dominant, whereas above the excitation-energy threshold the non-radiative transition is governed by this decay channel. These new decay channels in azabenzenes may be related to photoisomerization processes, which are known to proceed by irradiation of u.v. light corresponding to the S2â†�S0 absorption transition. The discussion is developed in relation to “channel three” in the parent hydrocarbon, benzene.
Comparative supercapacitance performance of CuO nanostructures for energy storage device applications

In the present study, three different morphologies of copper oxide (CuO) nanostructures; bud-, flower- and plate-shaped CuO structures were synthesized by a simple chemical method. Binder-included pseudocapacitor electrodes were prepared using bud- and flower-shaped CuO structures whereas, directly grown CuO-nanoplates on Ni foam were used as a binder-free electrode in a three-electrode setup for electrochemical studies. Remarkably, the binder-free CuO nanoplates electrode exhibited excellent specific capacitance of 536 F g−1 at a current density of 2 A g−1, whereas the binder-included electrodes of bud- and flower-shaped CuO exhibited 230 F g−1 and 296 F g−1, respectively, at a current density of 0.7 A g−1 in a 6 M KOH electrolyte. The cycling retention test and charge/discharge stability for the binder-free CuO nanoplates electrode showed 94% capacity retention after 2000 cycles and capacitance loss of only 11.3% over ∼1000 cycles at a current density of 4 A g−1 from charge/discharge measurements. Also, the binder-free CuO electrode showed higher energy and power densities of 29.4 W h kg−1 and 12.7 W kg−1, respectively, at 1.96 A g−1 in an asymmetrical device, when compared to the binder-included electrode of flower-shaped CuO.

De hecho, el debate está más que nunca vivo, las nuevas tecnologías se han insertado, cada vez más, en el ámbito educativo, durante el COVID-19, que ha implicado incluso la suspensión de actividades docentes presenciales que han conllevado el uso de las nuevas tecnologías en el aula de forma inmediata.
Frações de fósforo acumuladas em Latossolo argiloso pela aplicação de fosfato no sistema plantio direto

Increased phosphorus availability in the top soil layer of no-tillage systems can lead to a higher transformation from inorganic into organic phosphorus fractions of different labilities. The preferential phosphorus accumulation forms and fractions under the application of soluble phosphate rates in a no-tillage system were determined. During five and a half years, the following accumulated P2O5 rates: 0, 130, 180, 260, 360, 540, 720, 980, and 1.240 kg ha-1 of P2O5, were applied in the winter and/or summer, whereupon samples of the 0-10 cm layer of a clayey Rhodic Hapludox (Oxisol) were collected. Total, organic, inorganic, and microbial phosphorus, as well as six inorganic and three organic phosphorus fractions were determined in a decreasing lability sequence. The observed alterations in the total phosphorus content under phosphate addition were restricted to the inorganic fractions. The moderately labile fraction was the major sink for the applied phosphorus. The importance of labile phosphorus fractions increased in direct relation to the phosphate application rates. Labile and moderately labile organic phosphorus fractions in the soil were as important as the respective inorganic fractions, especially under low phosphate application rates.
Energy Levels of One‐ and Two‐Dimensional Anharmonic Oscillators

The energy levels of the one‐dimensional and the linear two‐dimensional Morse oscillators have been calculated by the method of Harris, Engerholm, and Gwinn in the harmonic‐oscillator representation. The method compares favorably with diagonalization of the exactly calculated Hamiltonian matrix. In the one‐dimensional case the calculations can be improved by using displaced basis functions.
Enteric Methane Emissions of Dairy Cattle Considering Breed Composition, Pasture Management, Housing Conditions and Feeding Characteristics along a Rural-Urban Gradient in a Rising Megacity

Greenhouse gas emissions from livestock farming and in particular enteric methane (CH4) from ruminants are criticized for being one of the main contributors to climate change. Different breeding, feeding and management strategies are tested to decrease these emissions, but a status quo analysis is also relevant to implement such measures. The present study aimed to analyze the concentration of CH4 in air exhaled by dairy cows along a rural-urban gradient of Bangalore, India. Urban, mixed and rural areas were defined based on a survey stratification index (SSI) comprising build-up density and distance to the city center. Using a laser methane detector (LMD), CH4 concentration was determined in 2-min spot measurements of exhaled air of 448 cows at three equally spaced visits between June 2017 and April 2018. Mean, maximum and CH4 concentration per duration of the overall measurement, eructation and respiration bouts were calculated. For the overall mean and respiration bouts, CH4 concentration was higher in cows from urban areas, which had also higher milk yield than cows from mixed and rural areas. Although no differences were found in terms of the intake level of fibrous diet components, the type of measurement location (indoor, half-outdoor or outdoor) and pasture access had an impact on CH4 concentration. To our knowledge, this is the first study using the LMD on-farm and in an urbanizing environment. The LMD measurements show variations in enteric CH4 emissions along the rural-urban gradient of Bangalore that reflect differences in dairy husbandry systems governed by the social-ecological context.
Response of Dry Bean to Nitrogen Fertilization and Inoculation with Rhizobium Tropici and Azospirillum Brasiliensis

ABSTRACT The dry bean (Phaseolus vulgaris L.) has significant economic importance in Brazil and is one of the most important sources of income, especially for small producers. This study aimed to evaluate the response of dry bean to different nitrogen (N) sources, using a completely randomized design, with five replicates. Treatments comprised five N sources [ammonium sulfate [(NH4)2SO4], calcium nitrate [Ca(NO3)2], potassium nitrate (KNO3), ammonium nitrate (NH4NO3), and urea] applied at 300 mg kg−1 N plus three additional treatments (inoculation with Rhizobium tropici, inoculation with R. tropici plus Azospirillum brasiliensis, and the control without N and inoculation). The yield components [grain yield (GY), shoot dry weight yield (SDWY), number of pods per pot (NPP), number of grains per pot (NGPt), pod weight (PW), and number of grains per pod (NGP)], and physiological components [water use efficiency (WUE), photosynthetic rate (A), and stomatal conductance (gs)] were evaluated. Inoculation with R. tropici and R. tropici plus A. brasiliensis did not induce significant effects on yield components when compared to those of the control. (NH4)2SO4 did not change the performance of most quantified yield components, whereas NH4NO3 showed increases in GY, SDWY, NPP, NGP, and PW as well as in WUE. KNO3 and Ca(NO3)2 resulted in increased performance of GY, SDWY, NPP, A, and gs compared to that in the control treatment and the isolated inoculant and its combination with A. brasiliensis. The amide source via urea showed the greatest increase in GY, with 56.5% more than that in the control.
Organic and Mineral Fertilization: Effects on Physical Characteristics and Boron Dynamic in an Agricultural Soil

Abstract The mineral and organic fertilizations on lettuce (Lactuca sativa L.) cultivation were investigated to understand the correlations between soil physical and mechanical indexes and boron (B) dynamic (adsorption, desorption, fractions) in soil. The fertilization with compost (derived by wine‐producing residues) and integrated fertilization (compost plus ammonium nitrate) increased the soil workability, as do the extent of aggregation, the water retention, and the cation exchange of the soil. The physical (colloids index, Ic) and mechanical (shear resistance, τ) properties showed a significantly higher value in compost and integrated fertilization plots. The biomass application to the soil influences the sorption B behavior, which is related to the soil shear strength and the compaction susceptibility; the Langmuir maximum adsorption for B was positively related with plastic deformation (De) and dry bulk density (Db) and negatively related to water infiltration (Wi), τ, and compressibility index (Cs). The B desorption was not modified by the variation on soil mechanical resistance; no correlation was found between B desorption index and physical–mechanical parameters of the soil. The B fractions, not readily available for plants, occluded in aluminium (Al) and iron (Fe) oxyhydroxides (Ox‐B) and organically bound (OM‐B), were negatively correlated with colloid index (Ic), Wi, τ, and moisture content (U), and were positively correlated with De, Db, and compressibility index (Cp, related to organic‐matter content of the soil).
