SUMMARYA field experiment was conducted at Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bangalore to study the effect of irrigation regimens on the biomass accumulation, canopy development, light interception and radiation use efficiency of sunflower. The treatments includes irrigating the plants at 0.4, 0.6, 0.8 and 1.0 cumulative pan evaporation. The results indicated that the aboveground biomass, canopy development, radiation interception and radiation use efficiency were influenced favorably by the irrigation regimens. Irrespective of the irrigation regimen, the radiation use efficiency of sunflower increased from 15 DAS to 75 DAS and then tended to decline. The decrease in RUE after anthesis is coupled with decrease in leaf nitrogen content. In general the RUE of sunflower ranged from 0.49 g MJ-1 to 1.84 g MJ-1 at different growth stages. The light transmission within the canopy increased exponentially with plant height and the canopy extension coefficient is found to be 0.8.

SUMMARYDuring the rainy season of 1998, a field experiment was established in Cocula, Guerrero (hot subhumid climate, Awo) and in Montecillo, México (semiarid climate, BS1), to evaluate the effect of nitrogen (0, 10 and 20 g m-2) and environment on phenology, yield and its components, water use efficiency (WUE), and crop evapotranspiration (ETc) and heat units (HU) accumulated during the growth cycle of sunflower (Helianthus annuus L.) cv. Victoria. The crop was planted on June 1 at a density of 7.5 pl m-2 in both climates. In Cocula, maximum and minimum temperatures were more extreme and rainfall was more intense, while soil was poor in total nitrogen, compared with Montecillo. Crop growth, yield and its components, and water use efficiency were affected significantly by the environment, nitrogen and the interaction environment * nitrogen. The crop cycle in the hot environment was 36 days shorter, with a greater accumulation of HU and ETc. Yield and its components and water use efficiency were significantly higher in Cocula. Nitrogen positively affected the evaluated variables. The interactive effect of environment * nitrogen was observed clearly, since in Cocula there was response to the application of nitrogen in most of the variables evaluated, while in Montecillo there was not.

SUMMARYThe objective of this work was to determine the number of reproductive structures in relation to the vascularization of sunflower capitulum in three sectors: outer, middle and center, and in four development stages: E2 (early floral button), E4 (late floral button), F3.2 (beginning flowering) and M0 (end flowering) according to the CETIOM code.Seeds of Dekalb G100 sunflower hybrid were sown at 72.000 pl/ha density and the capitula gathered at the indicated stages.At each stage, significant increases were noticed in the reproductive structures number from the outer sector to the center of capitulum. The number of vascular bundles per unit of surface showed a significant decrease from the outer sector to the center at E2 and E4 stages and a tendency to become stable at F3.2 and M0. The obtained values of surface covered by phloem per cm2 of capitulum, decreased remarkably from the outer sector to the center at E4 stage while at F3.2 and M0 minor but still important decreases were observed.The statistical analysis made on reproductive structures number in relation to vascular bundles number and surface covered by phloem showed low and insignificant correlations, respectively.
Experimental validation of the reaction mechanism models of dechlorination and [Zn] reclaiming in the roasting steelmaking zinc-rich dust process
Authors: Wang Hongyang , Dong Kai , Zhu Rong 
Published: April 2020

AbstractThe reaction mechanism models of dechlorination and [Zn] reclaiming in the roasting steelmaking zincrich dust process are studied. The dust collected from a steelwork contains 63.8% zinc and 3.18% chlorine (mass percent), of which, almost all zinc elements exist in ZnO and ZnCl2forms, and all the chlorine elements are stored in ZnCl2. When the dust is roasted at above 732∘C in an air atmosphere, the ZnCl2in the steelmaking zinc-rich dust is volatilized into steam and then oxidized into ZnO. Finding the position where the chemical reaction occurs is the key to determining the reaction mechanisms of dechlorination and [Zn] reclaiming. In this study, two groups of thermal experiments are designed and executed for roasting in different atmosphere environments and at different roasting temperatures. Based on the experiment results, the mechanism model is discussed and built, and the reaction of dechlorination and [Zn] reclaiming is shown to be a multi-step process. Because O2from the air cannot transmit into the dust particle interior or dust bed effectively, the chemical reaction of [Zn] reclaiming occurs in the external gas environment outside of the dust, where the [Zn] recalcining reaction should be limited by the dynamics of new nucleation of ZnO solids.
On the strain gradient bending deformations
Authors: Lazopoulos Konstantinos A. , Lazopoulos Anastasios K. 
Published: April 2020

AbstractBending deformations are reviewed in the context of strain gradient linear elasticity, considering the complete set of strain gradient components. It is well understood that conventional bending deformations depend on the collective uniaxial extension of axial fibers resulting in the dependence on the curvature of the neutral geometry of various (linear or surface) structures. Nevertheless, the deformation of each fiber depends not only on the local curvature of the neutral geometry but also on the distance of the fiber from the neutral axis. Hence, the strain gradient tensor of the conventional bending strain should include not only components along the neutral axis but also those on the transverse direction. The problems of bending and buckling, along with geometrically non-linear and post-critical behavior, are reviewed in the context of strain gradient elasticity considering not only conventional bending strain but also the complete components of the strain gradient.
Size effects in nanostructured Li-ion battery cathode particles
Authors: Natarajan Sundararajan , Aifantis Katerina 
Published: April 2020

Abstract
Cathode materials for Li-ion batteries exhibit volume expansions on the order of 10% upon maximum lithium insertion. As a result internal stresses are produced and after continuous electrochemical cycling damage accumulates, which contributes to their failure. Battery developers resort to using smaller particle sizes in order to limit damage and some models have been developed to capture the effect of particle size on damage. In this paper, we present a gradient elasticity framework,which couples the mechanical equilibrium equations with Li-ion diffusion and allows the Young’s modulus to be a function of Li-ion concentration. As the constitutive equation involves higher order gradient terms, the conventional finite element method is not suitable, while, the two-way coupling necessitates the need for higher order shape functions. In this study, we employ B-spline functions with the framework of the iso-geometric analysis for the spatial discretization. The effect of the internal characteristic length on the concentration evolution and the hydrostatic stresses is studied. It is observed that the stress amplitude is significantly affected by the internal length, however, using either a constant Young’s modulus or a concentration dependent one yields similar results.

Published: April 2020

Abstract
This paper improves on the issues of extreme data points and heterogeneity found in the linear programming data envelopment analysis (DEA) by presenting a cluster-adjusted DEA model (DEA with cluster approach). This analysis, based on efficiency, determines the number of clusters via Gap statistic and Elbow methods. We use the December quarterly panel data consisting of 122 U.S agricultural banks across 37 states from 2000 to 2017 to estimate the cluster-adjusted DEA model. Empirical results show differences in the estimated DEA efficiency measures with and without a clustering approach. Furthermore, using non-parametric tests, the results of Ansari-Bradley, Kruskal Wallis, and Wilcoxon Rank Sum tests suggest that the cluster-adjusted DEA model provides statistically better efficiency measures in comparison to the DEA model without a clustering approach.

AbstractProgenitor cells at the basal layer of skin epidermis play an essential role in maintaining tissue homeostasis and enhancing wound repair in skin. The proliferation, differentiation, and cell death of epidermal progenitor cells have to be delicately regulated, as deregulation of this process can lead to many skin diseases, including skin cancers. However, the underlying molecular mechanisms involved in skin homeostasis remain poorly defined. In this study, with quantitative proteomics approach, we identified an important interaction between KDF1 (keratinocyte differentiation factor 1) and IKKα (IκB kinase α) in differentiating skin keratinocytes. Ablation of either KDF1 or IKKα in mice leads to similar but striking abnormalities in skin development, particularly in skin epidermal differentiation. With biochemical and mouse genetics approach, we further demonstrate that the interaction of IKKα and KDF1 is essential for epidermal differentiation. To probe deeper into the mechanisms, we find that KDF1 associates with a deubiquitinating protease USP7 (ubiquitin‐specific peptidase 7), and KDF1 can regulate skin differentiation through deubiquitination and stabilization of IKKα. Taken together, our study unravels an important molecular mechanism underlying epidermal differentiation and skin tissue homeostasis.
Protein phosphatase PP2A regulates microtubule orientation and dendrite pruning in Drosophila

Published: April 2020

AbstractPruning that selectively eliminates inappropriate projections is crucial for sculpting neural circuits during development. During Drosophila metamorphosis, ddaC sensory neurons undergo dendrite‐specific pruning in response to the steroid hormone ecdysone. However, the understanding of the molecular mechanisms underlying dendrite pruning remains incomplete. Here, we show that protein phosphatase 2A (PP2A) is required for dendrite pruning. The catalytic (Microtubule star/Mts), scaffolding (PP2A‐29B), and two regulatory subunits (Widerborst/Wdb and Twins/Tws) play important roles in dendrite pruning. Functional analyses indicate that PP2A, via Wdb, facilitates the expression of Sox14 and Mical prior to dendrite pruning. Furthermore, PP2A, via Tws, governs the minus‐end‐out orientation of microtubules (MTs) in the dendrites. Moreover, the levels of Klp10A, a MT depolymerase, increase when PP2A is compromised. Attenuation of Klp10A fully rescues the MT orientation defects in mts or pp2a‐29b RNAi ddaC neurons, suggesting that PP2A governs dendritic MT orientation by suppressing Klp10A levels and/or function. Taken together, this study sheds light on a novel function of PP2A in regulating dendrite pruning and dendritic MT polarity in sensory neurons.
tRIP‐seq reveals repression of premature polyadenylation by co‐transcriptional FUS‐U1 snRNP assembly

Published: April 2020

AbstractRNA processing occurs co‐transcriptionally through the dynamic recruitment of RNA processing factors to RNA polymerase II (RNAPII). However, transcriptome‐wide identification of protein–RNA interactions specifically assembled on transcribing RNAPII is challenging. Here, we develop the targeted RNA immunoprecipitation sequencing (tRIP‐seq) method that detects protein–RNA interaction sites in thousands of cells. The high sensitivity of tRIP‐seq enables identification of protein–RNA interactions at functional subcellular levels. Application of tRIP‐seq to the FUS‐RNA complex in the RNAPII machinery reveals that FUS binds upstream of alternative polyadenylation (APA) sites of nascent RNA bound to RNAPII, which retards RNAPII and suppresses the recognition of the polyadenylation signal by CPSF. Further tRIP‐seq analyses demonstrate that the repression of APA is achieved by a complex composed of FUS and U1 snRNP on RNAPII, but not by either one alone. Moreover, our analysis reveals that FUS mutations in familial amyotrophic lateral sclerosis (ALS) that impair the FUS‐U1 snRNP interaction aberrantly activate the APA sites. tRIP‐seq provides new insights into the regulatory mechanism of co‐transcriptional RNA processing by RNA processing factors.
Desgaste superficial de adoquines: implementación y ajustes en la normativa ecuatoriana
Authors: Realpe Rivadeneira Guillermo Ricardo 
Published: April 2020

El control de calidad de los adoquines en el Ecuador ha permanecido invariable desde 1987, utilizando como criterio de calidad y durabilidad el valor de la resistencia a la compresión del bloque bajo el concepto de indicador global. Supone este indicador que al cumplir la especificación de resistencia, cubrirá exigencias tal como el desgaste superficial, por tanto la expectativas de la vida útil de la capa de rodadura. Sin embargo en los últimos años se ha verificado de manera general un deterioro temprano de las superficies de los adoquines a pesar del cumplimiento de los requerimientos de compresión establecidos en la norma ecuatoriana. En estas condiciones la Universidad, la industria de la construcción y el Instituto de normalización ecuatoriana decidieron dar origen a una nueva norma de control en el que se desglosa el indicador en varios parámetros físicos y mecánicos, empleando como documento base la norma europea EN 1338. Entre los parámetros, la cuantificación y valoración del desgaste superficial se constituyó en de mayor interés, tanto por el desconocimiento de la capacidad de desgaste superficial de la mayor parte de la producción en el país, así como el método de ensayo a utilizarse. El presente artículo, sobre la base de un tradicional análisis estadístico de 516 ensayos de desgaste superficial por medio del método de la banda ancha (EN 1338) realizados en el laboratorio de Materiales de Construcción de la Pontificia Universidad Católica del Ecuador entre los años 2010 a 2015, verificó el comportamiento de distribución normal simétrico en los dos lotes en el que fueron clasificados los datos; uno correspondientes a fábricas que mantienen procesos de control de calidad y otro a fábricas sin control además, cuantificó el valor de huella característico según el método de ensayo de desgaste en el período de análisis. Por medio de la información obtenida se ha justificado la necesidad del control del desgaste superficial así como la recomendación de establecer una especificación para el Ecuador, diferente a la establecida en la norma europea.

Absztrakt:
A krónikus limfoid leukémia (CLL) a leggyakoribb felnőttkori leukémia a fejlett
országokban. A CLL egy indolens lefolyású, gyógyíthatatlan betegség, mely a
kezelést követő relapszusokkal járhat, emiatt a betegek folyamatos követése
szükséges. Az elmúlt évek bővülő terápiás lehetőségei (pl.: alemtuzumab,
venetoclax) lehetővé tették a daganatos sejtek mennyiségének tartós és
drasztikus csökkenését, ezért szükségessé vált a visszatérő betegség minél
érzékenyebb detektálása. Erre nyújt lehetőséget a minimális, újabban mérhető
reziduális betegség (minimal residual disease: MRD)
meghatározása áramlási citometriai és molekuláris genetikai vizsgálati
módszerekkel. Az MRD-szint és a túlélés összefüggését vizsgáló klinikai
tanulmányok egyértelművé tették, hogy az alacsonyabb MRD-szint hosszabb
túléléssel jár együtt. Bár az MRD meghatározása jelenleg nem a klinikai rutin
része, amennyiben a jelenleg még futó klinikai vizsgálatok eredményei indokolttá
teszik meghatározását, áramlási citometriai módszeren alapuló vizsgálata a rutin
diagnosztika része lehet majd.

The living standard of people is constantly improving and the service industry is developing rapidly. In order to improve the competitiveness of enterprises in China, this paper mainly studies the behavioral characteristics of consumers when they buy products or services. Through the theory of planned behavior and the model of technological acceptance, the perceived value is taken as an important factor to reflect the characteristics of consumers' subjective purchasing behavior. Moreover, the EASI model is used to analyze the influence of service personnel on consumers' purchasing behavior in the service industry. Finally, this paper puts forward reasonable suggestions to enterprises.</p>
Narrating Emotions: Towards Deeper Understanding
Authors: Coetzee Jan K. 
Published: April 2020

Qualitative research aims at unwrapping the ordinary and the exceptional in order to bring us closer to a complete description and interpretation of life. People’s narratives are particularly effective in revealing deeper dimensions of experience and of meaning. Narratives always need to be read against the background of the empirical reality in which they are embedded. Most of the narratives referred to in this article are situated against the empirical reality of South Africa as a society in transition, still marred by inequality and inequity. One narrative, from a project conducted in the Czech Republic, shares some contextual characteristics with the South African examples—the Czech Republic is also a society in transition, previously employing institutional violence to suppress political dissent.
An important aspect when dealing with intense political and social transformation is the presence of highly charged feelings and emotions. As part of the contextualization for this article I briefly argue that the South African Truth and Reconciliation Commission (1996-1998) in many ways did the groundwork for a new appreciation of the sharing of emotional accounts and revelations pertaining to atrocities, injustices, and suffering. This Commission’s work prepared the way for recognition of the potential of such sharing to create a better understanding of the experience of life in a deeply divided context.
In the article, I argue for the establishment of a social encounter—a concept frequently used in the micro-sociological writings of Randall Collins—between researcher and research participant in an attempt to come to deeper levels of understanding. During episodes of emotional sharing of experiences and feelings a research participant often reveals deeper levels of social interaction—these revelations have the potential to open the way for a hermeneutical process towards understanding. Dramatic recall can lead to reconstructing a story that contains all the elements of what was originally heard, seen, and felt.
The article uses five examples of narratives containing moments of high levels of emotion—each example opening the way for better understanding of the experiences of the research participants.
