Phase transition study of ferroelectric copolymers by infrared spectroscopy in the submillimetric region

The infrared submillimetric technique is used to study phase transitions in Poly(vinylidene fluoride) and in Poly(vinylidene fluoride-trifluorethylene) copolymers. Copolymerization presents two important effects on the chain polarizability and thus on the submillimetric absorption spectra:The reduction of the chain polarizability linked to the introduction of TrFE units (less polar than the VDF ones); -From 20% to 40% in mole TrFE the copolymers present the TT conformation, more polar than the TG+TG- one presented for lower comonomer contents.The observed variations of the absorption coefficient (α) and of the imaginary part of the dielectric constant (ε“) are typically a combination of these effects associated to the presence of crystalline absorption bands.

Molecular Dynamics Simulations to Study Protein Folding and Unfolding

Proteins in solution fold in time scales ranging from microseconds to seconds. A computational approach to folding that should work, in principle, is to use an atom-based model for the potential energy (force field) and to solve the time- discretized Newton equation of motion (molecular dynamics, MD [1]) from a dena- tured conformer to the native state in the presence of the appropriate solvent.

Quantifying the sweetness intensity and impact of aroma in honey from four floral sources

Abstract Unlike many commercial sweeteners for which sweetness dose‐response curves have been constructed, honey's sweetness has yet to be quantified. Honey differs from most commercial sweeteners in that it has a robust aroma; this aroma may impact its perceived sweetness. This study quantified the sweetness intensity and the impact of aroma on the perceived sweetness of four different honey varieties (clover, wildflower, alfalfa, and orange) compared to sucrose. Each sweetener evaluated was diluted to six concentrations in water ranging from 12.5 g/L to 125 g/L. Panelists ( n = 55) rated the sweetness intensities with and without aroma, in replicate, on the Global Sensory Intensity Scale. Additionally, the volatile organic compounds in the honey samples were profiled using gas chromatography‐mass spectrometry (GC/MS) analysis. Honey and sugar were equivalently sweet at a given concentration (g/L), with aroma present ( p = 0.251). Additionally, honey and sugar were not equivalently sweet without aroma; aroma significantly increased sweetness intensities for all sweeteners ( p = 0.042) and especially honeys. In a 100 g/L solution, the aromas in honey increased its sweetness by 23%–43%, depending on the floral source. Compounds with sweet aroma characteristics were identified at high concentrations in all honey samples using GC/MS analysis, including furfural, benzaldehyde, benzene acetaldehyde, and dimethyl sulfide. Additionally, (S)‐limonene and toluene were present in high quantities in the orange and alfalfa samples. This study can inform appropriate honey usage levels and identify major volatiles that may enhance sweetness. Practical Application Honey sweetness has not been determined quantitatively, despite the widespread use of honey among consumers and product formulators. Sweetness enhancement by honey aroma volatiles may support a reduction in added sugars while maintaining sweetness intensity.

A Sequence Component Based Continuation Power Flow Model for Electric Power Grid Considering Transmission and Distribution System

Integration of Inverter Based Resources (IBRs) in the distribution grid and bulk grid has posed new challenges to the long-term voltage stability of the integrated electric Transmission and Distribution (T&D) system. The main challenges include, but are not limited to, IBR variability and intermittence, the effect of a large number of DERs, distribution grid unbalances, the effect of load types, and the interaction of controllable devices such as voltage regulators. This paper proposes a new three-sequence integrated T&D continuation power flow (SI-CPF) model for analyzing the voltage stability of the power grid considering, grid and load unbalance, various load types, and renewable energy variations, in a combined T&D simulation that consider all the phases of transmission and distribution network. Results show that SI-CPF can provide the weak phase voltage stability margin of the power grid more efficiently and accurately considering a three-phase integrated T&D network.

Aggressive Surgical Management for Metastatic Liver Tumors From Squamous Cell Carcinomas: Report of Three Cases

The use of hepatectomy for the treatment of metastatic liver tumors (MLTs) arising from squamous cell carcinomas (SCCs) has not been well investigated. The use of hepatectomy for MLTs from SCCs, especially in advanced cases, needs further investigation. Three patients with SCC-derived MLTs underwent hepatectomy. On clinicopathologic examination, the primary lesions were found to be oral cancer, lung cancer, and oropharyngeal cancer, with synchronous metastasis in 2 patients and metachronous metastasis in 1 patient. One case also involved adrenal metastasis, and another involved direct invasion of the diaphragm and lung. In all cases, surgery was performed to eliminate any residual tumor tissue. After the hepatectomy, 1 patient died (22 months postoperatively) of an unrelated disease, 1 remains alive (30 months postoperatively) with a recurrent tumor, and 1 remains alive (60 months postoperatively) without recurrence. For the patients with solitary MLT derived from SCC, hepatectomy gives a chance for a cure. Thus, aggressive hepatectomy is an important modality in the multidisciplinary approach for controlling SCC-derived MLTs.

A reaction-diffusion model for the production of autowaves

There are many examples of natural processes in which a substance must travel a trajectory, avoiding obstacles to reach an objective, using a mechanism for orientation and navigation. Such mechanism can be implemented using attraction by autowaves. The linear theory [1],[3],[6] lets to predict the conditions in which a reaction-diffusion system [1]–[12] has a raising oscillating behavior in the initial phase. In this paper a model is described for the production of autowaves [2],[4],[7]–[10], in agreement with the linear theory. Some results of simulation obtained with the model are shown.

Introduction to electrocardiogram interpretation: part 2

Twelve-lead electrocardiograms (ECGs) record 12 different views of cardiac electrical activity, or leads. They therefore provide more information than bedside monitors, which usually record one or sometimes two leads. Many acutely ill patients have 12-lead ECGs recorded either on admission to hospital, before undergoing operations or when specific cardiac concerns have arisen. Traditionally, ECGs have aided clinical diagnoses and, by learning how to understand and interpret them, nurses will know when they need to summon expert help. This article describes what each of the 12 leads represents, outlines the main indications for recording 12-lead ECGs and identifies likely causes of error in interpreting them.

A Perfect Plastic Material for Studies on Self-Propelled Motion on the Water Surface

We describe a novel plastic material composed of camphene, camphor, and polypropylene that seems perfectly suited for studies on self-propelled objects on the water surface. Self-motion is one of the attributes of life, and chemically propelled objects show numerous similarities with animated motion. One of important questions is the relationship between the object shape and its motility. In our paper published in 2019, we presented a novel hybrid material, obtained from the solution of camphor in camphene, that allowed making objects of various shapes. This hybrid material has wax-like mechanical properties, but it has a very high tackiness. Here, we report that a small amount of polypropylene removed this undesirable feature. We investigated the properties of camphor–camphene–polypropylene plastic by performing the statistical analysis of a pill trajectory inside a Petri dish and compared them with those of camphor-camphene wax. The plastic showed the stable character of motion for over an hour-long experiment. The surface activity of objects made of plastic did not significantly depend on the weight ratios of the compounds. Such a significant increase in usefulness came from the polypropylene, which controlled the dissipation of camphor and camphene molecules.

Risk factors for recurrence of borderline ovarian tumors in France: A multicenter retrospective study by the FRANCOGYN group

Background: Borderline ovarian tumors (BOTs) although rare, have shown an increase in the incidence worldwide. Although the survival rate is high, the recurrence rate is estimated to be between 5% and 34%. The objective of this study was to identify risk factors for recurrence of BOTs. Methods: This retrospective multicenter study included 493 patients treated surgically for BOT between January 2001 and December 2018. Results: Thirty-seven patients showed recurrence (group R, 7.5%), while 456 did not (group NR, 92.5%). With an average follow-up of 30.5 months (1-276), the overall recurrence rate was 7.5%. Recurrence rates for the BOT and invasive types were 5.7% (n=28) and 1.4% (n=7), respectively. The mean time to recurrence was 44.1 (3-251) months. Univariate analysis showed that age at diagnosis, type of surgical procedure, histological type, and FIGO stage were factors influencing recurrence. Multivariate analysis showed that the risk factors for recurrence of BOT were conservative treatment (OR=7 [95% CI 3.01-16.23]; p<0.05) and advanced FIGO stage (OR=5.86 [95% CI 2.21-15.5]; p<0.05). Conclusion: To the best of our knowledge, this multicenter study was one of the largest studies on the risk factors for BOT recurrence. Conservative treatment and advanced FIGO stage were identified as risk factors for BOT recurrence. These results reinforce the need for restaging of patients who did not have an optimal initial surgical staging so as not to avoid missing a tumor in the advanced stage. Referral to a surgical oncology center is suggested to optimize overall patient management.

Radiation Proctitis in Patients With Locally Advanced Cervical Cancer Treated by Chemoradiation

Objectives: Radiation proctitis is a misunderstanding complication of chemoradiation in locally advanced cervical cancer. The objective of our study is to provide a detailed description and analysis of predictive factors associated with radiation proctitis in a retrospective cohort of patients treated by chemoradiation for locally advanced cervical cancer. Methods: All patients treated by exclusive chemoradiation or chemoradiation followed by brachytherapy for locally advanced cervical cancer from 2011 to 2017 were included in the study. A bivariate analysis was conducted to establish correlations between the occurrence of radiation proctitis and various clinical and technical variables. Results: A total of 128 patients were included in the study. The mean dose (SD) to the planning target volume was 47.1 Gy (6.2). Fifty-nine (46.1%) patients underwent brachytherapy. Sixteen patients (12.5%) developed radiation proctitis, grade 2 or higher in 12 patients (9.3%). In univariate analysis, anticoagulant or antiplatelet treatments ( P =0.039), older age ( P =0.049), rectal volume irradiated at 40 Gy ( P =0.01) and 30 Gy ( P =0.037) were significantly associated with the occurrence of a grade ≥2 radiation proctitis. The delivered dose to 2 cm 3 of rectum (D2cm 3 ) showed a potential association with the occurrence of radiation proctitis of all grades ( P =0.064). Conclusions: This study highlights clinical and technical factors that should be considered in assessing the risk of radiation proctitis. These results contribute to a better understanding of this complication.

Conductivity and Relaxation Phenomena in Proton and Anion Exchange Membranes by Broadband Electric Spectroscopy

Understanding of the relationship existent between structure and ion conduction mechanisms is crucial in order to trigger the development of new high performing proton and anion conducting membranes for applications in fuel cells [1].&#13;\nIt has been suggested that conductivity in ion conducting materials occurs via a number of different processes. The main conductivity processes are correlated to: a) the charge migration events of ions between coordination sites in the host materials; [2-5] and b) the relaxation phenomena involving the dynamics of the host materials [2-5]. Ions “hopping” to new chemical environments can lead to successful charge migration only if ion-occupying domains relax via reorganizational processes [2-5], which are generally coupled with relaxation events associated with the host matrix. A useful technique to study and understand ion conducting mechanisms and to correlate this to the morphology of the electrolytes is Broadband Electric Spectroscopy (BES).&#13;\nIn this presentation, an overview of the application of BES in the study of the charge transfer mechanisms in pristine and hybrid inorganic-organic proton-conducting and anion-conducting membranes is provided. Furthermore, the models adopted for the interpretation of BES results as well as some case studies of conductivity mechanisms are elucidated. &#13;\nAcknowledgements: The authors thank the StrategicProject “From materials for Membrane electrode Assemblies to electric Energy conversion and SToRAge devices” (MAESTRA) of the University of Padova for funding this activity. &#13;\nReferences&#13;\n[1]\tPolymer Electrolytes: Fundamentals and Applications; Sequeira, C.; Santos, D., Eds.;Woodhead Publishing Limited: Oxford, 2010. &#13;\n[2]\tDi Noto, V.

Active portfolio management: The power of the Treynor-Black model

Abstract: The performance of active portfolio methods critically depends on the forecasting ability of the security analyst. The Treynor-Black model provides an efficient way of implementing active investment strategy. Despite its potential benefits, the Treynor-Black model appears to have had little impact on the financial community, mainly because it has been believed that the precision threshold of alpha forecasts used as inputs to the model is too high. We seek to lower the threshold of forecast precision needed to beat a passive-portfolio strategy by improving the econometric methods used in constructing portfolios from security analyst forecasts. We apply shrinkage estimation to beta coefficients and to discount functions for forecasts of stock abnormal returns. OLS estimates, Least Absolute Deviations (LAD) estimates and shrinkage LAD estimates are compared by contribution to portfolio performance. Despite correlations between forecasts and realizations of abnormal returns as low as 0.04, the shrinkage LAD methodology yields superior performance in outof-sample experiments.

ANTAGONISM BY DIBUTYRYL ADENOSINE CYCLIC 3',5'-MONOPHOSPHATE AND TESTOSTERONE OF CELL ROUNDING REACTIONS

In an attempt to understand further the mechanism of the morphological and functional "reverse transformation" of CHO-K1 cells induced by dibutyryl adenosine cyclic 3',5'-monophosphate (cAMP) and testosterone, the kinetics of variation in the susceptibility of cells to rounding after the addition or deletion of dibutyryl cAMP and testosterone have been investigated. Changes in susceptibility to cell rounding upon removal of divalent cations or pulse exposure to concanavalin A were complete within 0.5–1 h after addition or deletion of drug. In comparison, the gross conversion of CHO-K1 cells from epithelial- to fibroblast-like morphology after drug treatment or the converse change after drug removal required 8 or 4 h, respectively. The effects on cell rounding are not caused by an effect of dibutyryl cAMP upon cell growth rate. Inhibitor experiments indicate that the changes investigated do not require continued RNA or protein synthesis and are not prevented by agents which depolymerize microtubules.

Analytical and Numerical Approach to the Romanian Medieval Church Structures

Whenever interventions on medieval churches are necessary, they must be approached as a whole, based on a numerical analysis of the load-bearing structure, especially if exceptional actions, like seismic ones, are present. Numerical analysis results can be successfully used in the assessment of quantitative elements for timber load-bearing structures. Nonetheless, masonry load-bearing subunits are more difficult to design and assess, results of the calculations made in case of elastic behaviour of the masonry structure being valid only until the first cracks. Numerical analysis can indicate, from a qualitative viewpoint, the behaviour of load-bearing structures of church buildings.. This paper presents the modelling principles of various types of load-bearing structural units belonging to medieval churches, which are subjected to dead loads and non-gravity actions, including Lutheran Church in Bistrita, Reformed Church in Aiud, Lutheran Church in Drauseni. , drafted within the Built Heritage Conservation Research and Design Centre – Utilitas, Cluj-Napoca City. It applies to three case studies, displaying their structural behaviour and contributing to the selection of appropriate strengthening methods
