To comply with upcoming legal restrictions concerning hazardous substances the contact material cadmium oxide (Ag/CdO) must be replaced in many applications. This paper deals with house-wiring switches for domestic and industrial applications. The tests were performed on commercial house-wiring switches with silver/nickel (Ag/Ni) on the fixed contact and Ag/CdO on the movable contact. A variety of silver-based contact materials such as Ag/Ni, silver/tin oxide (Ag/SnO 2 ) and silver/zinc oxide (Ag/ZnO) were tested in place of the Ag/CdO on the movable contact, applying lamp loads as well as capacitive loads with a rated current of 16 A at 250 V AC. While Ag/Ni as the movable contact led to welding problems, it was found that Ag/ZnO 92/8 with silver tungstate (Ag 2 WO 4 ) additive performed particularly well with regard to service life as well as anti-welding behavior and over temperature properties. The switching results are discussed in terms of the arc – contact material interaction and contact material micro sections after service life.
Removal of Pyrethrin from Aqueous Effluents by Adsorptive Micellar Flocculation

The equilibrium adsorption of pyrethrin onto aggregates formed by the flocculation of micelles of the surfactant sodium dodecyl sulphate (SDS) with aluminium sulphate is reported. The experimental results were analysed using different adsorption isotherms (Langmuir, Freundlich, Redlich-Peterson, Sips, Radke-Prausnitz, Temkin, linear equilibrium, and the Dubin-Radushkevich isotherms). The Freundlich and linear equilibrium isotherms best describe the adsorption of pyrethrin onto SDS micellar flocs, with the Freundlich adsorption constant, , and the mass distribution coefficient, , of 64.266 ((mg/g)(L/mg)1/n) and 119.65 L/g, respectively. Applicability of the Freundlich adsorption model suggests that heterogeneous surface adsorption affects the adsorption. The mean free energy value estimated using the Dubinin-Radushkevich isotherm was 0.136 kJ/mol indicating that physisorption may be predominant in the adsorption process.

Metamaterial structures provide innovative ways to manipulate electromagnetic wave responses to realize new applications. This paper presents a conformal wideband metamaterial array that achieves as much as 10: 1 continuous bandwidth. This was done by using interelement coupling to concurrently achieve significant wave slow-down and cancel the inductance stemming from the ground plane. The corresponding equivalent circuit of the resulting array is the same as that of classic metamaterial structures. In this paper, we present a wideband Marchand-type balun with validation measurements demonstrating the metamaterial (MTM) array’s bandwidth from 280 MHz to 2800 MHz. Bandwidth reconfiguration of this class of array is then demonstrated achieving a variety of band-pass or band-rejection responses within its original bandwidth. In contrast with previous bandwidth and frequency response reconfigurations, our approach does not change the aperture’s or ground plane’s geometry, nor does it introduce external filtering structures. Instead, the new responses are realized by making simple circuit changes into the balanced feed integrated with the wideband MTM array. A variety of circuit changes can be employed using MEMS switches or variable lumped loads within the feed and 5 example band-pass and band-rejection responses are presented. These demonstrate the potential of the MTM array’s reconfiguration to address a variety of responses.
A review of the dissociative disorders : from multiple personality disorder to the posttraumatic stress

Título: Una revisión de los trastornos disociativos: de la personalidad múltiple al estrés postraumático. Resumen: Este trabajo trata la idea de disociación, los trastornos disociativos y su relación con los procesos de conciencia. Se centra en el trastorno de personalidad múltiple y el trastorno de estrés postraumático, desde la perspectiva del diagnóstico y del tratamiento. Ambos grupos de trastornos polarizan el debate sobre las categorías diagnósticas con síntomas disociativos. Se revisan las ideas sobre disociación, hipnosis y suicidio asociadas a estos trastornos. Parece darse una falta de consenso en cuanto a la naturaleza misma de la disociación con implicaciones teóricas, empíricas y clínicas. Completa esta revisión la comparación desde sus inicios, hace poco más de un siglo, con el panorama actual y las nuevas tendencias en las investigaciones que desde las neurociencias están relacionando los procesos cognitivos con los fenómenos y trastornos disociativos. Palabras clave: trastornos disociativos; trastorno de personalidad múltiple; trastorno de estrés postraumático; fenómenos disociativos; hipnosis; ideación suicida. Abstract: In this paper we review the idea of dissociation, dissociative disorders and their relationship with the processes of consciousness. We will deal specifically with multiple personality disorder and posttraumatic stress disorder. Both polarize the discussion of diagnostic categories with dissociative symptoms. This review compares the initial ideas (one century old) with the current scenario and emerging trends in research, which are relating cognitive processes and dissociative phenomena and disorders from a neuroscientific approach. We discuss the ideas on dissociation, hypnosis and suicide associated with these disorders. There seems to be a lack of consensus as to the nature of dissociation with theoretical, empirical and clinical implications.
Training Techniques for Presence-Only Habitat Suitability Mapping with Deep Learning

The goal of habitat suitability mapping is to predict the lo-cations in which a given species could be present. This is typically accomplished by statistical models which use envi-ronmental variables to predict species observation data. The relationship between the environmental characteristics of a location and the species that live there is likely to be quite complex, so deep learning models would seem natural to use. In practice, there are biases in the training data which present obstacles to standard deep learning approaches. First, large-scale species observation collections typically consist of presence-only data, which means we only have locations where a species has been observed (not where it has been confirmed to be absent). Second, the class distribution tends to be long-tailed. In this work we examine training tech-niques to mitigate these challenges: (i) a method for sharing species information between nearby observations and (ii) a curriculum learning strategy to reduce class imbalance early in training. These methods enable us to outperform state-of-the-art results on the GeoLifeCLEF 2020 dataset and suggest fruitful directions for future work.
Solution structures of methyl aldopyranosides revealed by vacuum-ultraviolet electronic circular-dichroism spectroscopy

Vacuum-ultraviolet (VUV) electronic circular-dichroism (ECD) spectra of methyl β-D-glucopyranoside (methyl β-D-Glc), methyl α -a ndβ-D-galactopyranosides (methyl α -a ndβ-D-Gal), and methyl α -a ndβ-D-xylopyranosides (methyl α -a ndβ-D-Xyl) were measured down to 163 nm in aqueous solution using a synchrotron-radiation VUV-ECD spectropho- tometer. Five methyl aldopyranosides exhibited characteristic ECD spectra depending on the gauche (G) and trans (T) con- formations of the hydroxymethyl group at C-5 and the α-/β-anomer configurations of the methoxy group at C-1. To elucidate the contributions of these structures to the spectrum, the ECD spectra of three rotamers (GT, GG and TG) of methyl β-D-Glc, methyl α-D-Gal and methyl β-D-Gal were calculated using a time-dependent density functional theory and molecular dynam- ics simulations. These theoretical spectra were very similar to those observed experimentally, indicating that the GT and GG rotamers show negative and positive ECD around 170 nm, respectively, and that the α -a ndβ-anomers exhibit negative and positive ECD around 160 nm, respectively. These spectral differences between the two rotamers and between the two anomers were attributable to changes in steric configurations, including the intramolecular hydrogen bond around the ring oxygen and the methoxy oxygen, respectively. These relationships were supported by the ECD spectra experimentally observed for methyl α-D-Xyl and methyl β-D-Xyl, demonstrating that the VUV-ECD spectroscopy is a powerful technique for characterizing the structures of saccharides in aqueous solution.
Quality Matters and Not Quantity: Evidence on Productivity Impacts of Extension Service Provision in Ethiopia

This paper contributes new empirical evidence and nuanced analysis on the gender difference in access to extension services and how this translates to observed differences in technology adoption and agricultural productivity. We employ a cross-sectional instrumental-variable regression method using a regionally-representative dataset of more than 7,500 households and 32,000 plots in four major regions in Ethiopia that was collected during the 2010 main season. Results suggest that female heads of households and plot managers are less likely to get extension services and less likely to access quality services than their male counterparts after controlling for plot, household, and village level characteristics. Receiving advice from development agents (DAs) is strongly and positively related to adoption of improved seed and fertilizer for both females and males, as hypothesized. However, beyond their influence through fertilizer and improved seed use, visits by or advice from DAs are not significant in all productivity models estimated for females and males, which is in contrast to past studies. In some crop-specific productivity models estimated, it is the perceived quality of DA visits and access to radio that appear to be strongly and positively significant in explaining productivity levels for both female and male farmers. Our results highlight the need for productivity models that are stratified by gender and crop.
Stratosphere-troposphere exchange in the vicinity of a tropopause fold

Abstract. Transport of air masses from the stratosphere to the troposphere along tropopause folds can lead to peaked ozone concentrations at ground level and hereby influence the long-term trend of tropospheric ozone. To improve the understanding of responsible processes and preferred regions of exchange, transient and reversible exchange processes in the vicinity of a tropopause fold are analysed on the basis of a case study. The global and regional atmospheric chemistry model system MECO(n), which couples the limited-area atmospheric chemistry and climate model COSMO-CLM/MESSy to the global model ECHAM5/MESSy for Atmospheric Chemistry (EMAC) is applied. Using similar process parametrisations in both model instances, the system allows for very consistent, simultaneous simulations at different spatial resolutions. Simulated ozone enhancements at ground level, caused by descending stratospheric air masses, are evaluated with observational data. Because of the coarse resolution of the global model, the observed ozone enhancements are not captured by the global model instance. However, the results of the finer resolved, regional model instance coincide well with the measurements. Based on the combination of Eulerian and Lagrangian analysis methods it is shown that stratosphere-troposphere-exchange (STE) in the vicintity of the tropopause fold occurs in regions of turbulence and diabatic processes. Within the framework of a Lagrangian study the efficiency of mixing along a tropopause fold is quantified, showing that almost all (97 %) of the air masses originating in the tropopause fold are transported into the troposphere during the following two days.

: We construct invariant sets for the 2d-dimensional generalization of the sawtooth map which are semi-conjugate to any incommensurate rotation vector. When d $. 2 we show that these are Cantor sets. These invariant sets are hyperbolic, and we give a structural stability argument to show the existence of cantori for a non-trivial class of smooth symplectic maps.

Comparison of different staining methods for coffee proteomic analysis.

Proteomic methods, such as bidimensional electrophoresis (2-DE) and mass spectrometry, have been extensively used for the study of protein differential expression in several plants including Arabidopsis thaliana, rice and wheat. Specifically in the 2-DE method, deep attention must be given to the protein staining technique, which often involves silver nitrate or Coomassie Brilliant Blue (CBB). Silver staining is usually preferred over CBB due to the higher sensitivity obtained. Nevertheless, silver-staining resolution could significantly vary according to the studied organism and more specifically to the researched tissue. In Coffea spp. , 2-DE analysis has been rarely employed. Some studies of protein expression have been reported in this culture mainly involving the biosynthesis of caffeine and metabolism during seed germination. The study of the global protein expression in coffee plants in response to biotic stress conditions had not been reported until now. Phytonematode infection can be considered one of the most important biotic stresses that affect coffee production and Meloidogyne paranaensis is one of the major nematode species that infects coffee plants. In this report, the protein expression of infectedand non-infected roots of coffee (Coffea canephora) were analyzed and the protein pattern determined by 2-DE. Gels were stained with silver nitrate or CBB, in order to obtain an optimized method for proteomic analysis of plant-nematode interaction. The 2-DE analysis revealed an enhanced number of protein spots, as well as differentially expressed proteins, when CBB was used. A total of approximately 70 and 100 spots were observed in silver and CBB stained gels, respectively. Moreover, 18 differentially expressed proteins were observed in CBB gels, and only 8 in the silver stained gels. This report showed that the staining method was crucial for an optimized protein analysis of coffee. Similar results were obtained for cotton roots and therefore these results may be extended to other plant species in order to better understand the host-pathogen interaction.
Transparency in Information Acquisition: A Bargaining Experiment

We analyze how transparency affects information acquisition in a bargaining context, where proposers may chose to purchase information about the unknown outside option of their bargaining partner. Although information acquisition is excessive in all our scenarios we find that the bargaining outcome depends crucially on the transparency of the bargaining environment. In transparent games, when responders can observe whether proposers have acquired information, acceptance rates are higher. Accordingly, in transparent bargaining environments information is more valuable, both individually and socially.
Direction finding using minimum redundancy MIMO radar

An augmented covariance matrix, which has the characteristics of Hermitian and Toeplitz, is constructed for minimum redundancy (MR) multiple-input multiple-output (MIMO) radar to implement direction finding using Capon algorithm. A diagonal loading technique is employed to avoid non-positive definite of the covariance matrix. The diagonal loading level is adjusted adaptively according to the eigenvalues of the covariance matrix. The proposed method not only expands the system degrees-of-freedom (DOFs), but also has robust spatial spectrum estimation performance. In addition, the method requires no priori knowledge of the number of targets. Simulation results showing the performance improvement of the proposed method is presented. (4 pages)
Triggered fault slip on June 17, 2000 on the Reykjanes Peninsula, SW‐Iceland captured by radar interferometry

Dynamically triggered seismicity followed shortly after a Ms 6.6 earthquake in Iceland on June 17, 2000. Smaller earthquakes occurred on the Reykjanes Peninsula up to 100 km from the mainshock rupture. Using interferometric analysis of Synthetic Aperture Radar images (InSAR), we measure crustal deformation associated with three triggered deformation events. The largest of these occurred at Lake Kleifarvatn, 85 km west of the mainshock epicenter. Modeling of the InSAR data reveals strikeslip on a north‐striking fault, with a geodetic moment of 6.2 × 1017 Nm, equivalent to magnitude Mw 5.8 earthquake. A seismological estimate of the moment is not yet available, because the seismic signature of this event is partly hidden by the mainshock waveform. The paucity of aftershocks on the triggered rupture plane suggests some aseismic slip there, compatible with a thin seismogenic crust, high heat‐flow, hydrothermal alteration and the presence of fluids in the area.
Effect of Bit Line Voltage Stress on Half-Selected Device in 1T1R Array

Resistive random access memory (RRAM) becomes one of the solutions of embedded memory under advanced technology node. In this paper, we investigate the program disturb issues for the half-selected cell in 1T1R array. By utilizing the stress testing and RTN measurement, we conclude that the high source-drain voltage induced excess defects in the oxide layer is the main reason for the degradation of the FinFET. Therefore, the program voltage applied on BL of 1T1R array needs to be controlled to guarantee the reliability. Keywords: 1T1R, FinFET, half-selected cell, disturbance
Title Aging and Property Prices : A Theory of Very Long Run Portfolio Choice and Its Predictions on Japanese Municipalities in the 2040 s

This paper investigates the effect of aging population on property (land) prices. A theory of very long run portfolio choice is developed for a transition economy from young and growing to rapidly aging population and applied to estimate property price inflation in Japanese municipal markets. The results are stunning. The simulation results in which income factors are assumed to be fixed at the 2005-2010 growth level suggest that the average residential property price (land price) in the Japanese municipalities may decrease as much as 19 percent from the present to 2020, 24 percent to 2030, and 32 percent to 2040.

INTRAOPERATIVE EVALUATION OF ACHIEVED BONY RESECTIONS DURING TKA IS IT CAOS SYSTEM-DEPENDENT?

IntroductionComputer-assisted orthopaedic surgery (CAOS) has been shown to help achieve accurate, reliable and reproducible prosthesis position and alignment during total knee arthroplasty (TKA) [1]. A typical procedure involves inputting target resection parameters at the beginning of the surgery and measuring the achieved resection after bone cuts. Across CAOS systems, software/hardware design, mechanical instrumentation, and system-dependent work flow may vary, potentially affecting the intraoperative measurement of the achieved resection. This study assessed the cumulative effect of system-dependent differences between two CAOS systems by comparing the alignment deviation between the measurement of the achieved resection and the targeted parameters.Materials and MethodsTKA resections were performed on 10 neutral whole leg assemblies (MITA knee insert and trainer leg, Medial Models, Bristol, UK) by a board-certified orthopaedic surgeon (BH) using System I (5 legs, ExactechGPS®, Blue-Ortho, Grenoble, FR.
The LEP G-2548A Polymorphism is not Associated with Breast Cancer Susceptibility in Obese Western Mexican Women

Breast cancer incidence and the prevalence of obesity have considerably increased in Mexican women. The LEP G-2548A polymorphism has been associated with obesity and breast cancer risk in several ethnic populations. We hypothesize that G-2548A LEP polymorphism could be associated with breast cancer risk in women Mexican population. A total of 319 women were included in this study, 130 breast cancer patients and 189 control women. The data collected included anthropometric measurements and menopausal status, and a blood sample was obtained to evaluate SNPs using a PCR-RFLP analysis. No statistically significant associations were identified between breast cancer risk and the LEP G-2548A polymorphism in obese or normal-weight subgroups regardless of menopausal status. Our findings suggest that the LEP G-2548A polymorphism is not associated with breast cancer risk in obese western Mexican women. Our results indicate that, for western Mexican women, the LEP G-2548A polymorphism does not affect breast cancer susceptibility in obese or normal-weight subgroups regardless of menopausal status.
Identification of Potential Sites for Harvesting Rainwater Using Geospatial Techniques

Rain Water harvesting (RWH) is a need of current research and due to growing water crisis in the world, it is expected that two third of the world population will be exposed to water scarcity by 2025. Rainwater Harvesting (RWH) is the best technique which can be used effectively to collect the unutilized surface runoff and increase the groundwater recharge. But these structures have to be located at places where water is available in excess and conditions are favorable for enhanced infiltration. Therefore, the research objective of the presented work is to identify rainwater harvesting potential site using Multi Criteria Analysis (MCA) integrated with Hydrological Modeling (HM), Geographical Information System (GIS) and Remote Sensing (RS) in Prayagraj District, South-Eastern part of Uttar Pradesh, India. We have utilized thematic layers such as Slope, Soil, Land Use Land Cover maps, Drainage Network and Curve Number to evaluate potential zones of RWH. From the obtained results, it is found that potential zones for harvested rainwater could play a critical role to establish check dams for RWH and to prevent water scarcity in next few decades.
