Dumond, Mark, David Dumond, Cheryl Cook, Brett Duffner e Julie Laribee. "A Clinical Evaluation of the Correlation and Reprodicibility Of Three Automated Devices For Measurement of Activated Clotting Times". Journal of ExtraCorporeal Technology 22 (1990): 27–29. http://dx.doi.org/10.1051/ject/199022s027.
Abstract (sommario):
The Activated Clotting Time (ACT) assumes an important role in documentation of adequacy of perfusion. Therefore, it is important to document the correlation and reproducibility of automated systems currently available to measure the ACT value. During surgical procedures of 37 patients requiring cardiopulmonary bypass a blood sample was drawn in a single syringe and ACT values obtained using four Hemotec ACTs (T-ACT), four Hemochron ACTs (M-ACT), and two Sonoclot ACTs (S-ACT). Sample points with the mean of two of the three sets of ACTs exceeding 650 were excluded and the values were divided into heparinized (ACTH) (n=44) and nonheparinized (ACTN) (n=58) groups. Group Mean Value Avg. Std. Dev. r 2/T-ACTN r w/H-ACTN r w/T-ACTH r w/H-ACTH T-ACTN 104 3 - .638 - - H-ACTN 128 5 .638 - - - S-ACTN 138 11 .663 .580 - - T-ACTH 551 48 - - - .224 M-ACTH 514 69 - - .224 - S-ACTH 768 98 - - .041 .244 The very poor correlation of the three systems raises doubts as to interchangeability of ACT values from each system. The reproducibility (based on the size of the STD. DEV.) of the Hemotec system is significantly better than the Sonoclot.

Barr, Emma, Judith Neubauer e Celine Gelinas. "516 LinkedIn Marketing Strategies to Drive NJ ACTS Regulatory Core Engagement". Journal of Clinical and Translational Science 6, s1 (aprile 2022): 106. http://dx.doi.org/10.1017/cts.2022.310.
Abstract (sommario):
OBJECTIVES/GOALS: Our purpose is to promote traffic toward the NJ ACTS Regulatory Cores recently launched website and increase investigator engagement through marketing strategies on LinkedIn. Landscaping to characterize the profiles of researchers on LinkedIn was also completed to estimate the feasibility of engaging with a target population on LinkedIn. METHODS/STUDY POPULATION: Insight gathering was performed to analyze what percentage of researchers possessed a LinkedIn profile and actively used their accounts. A sample population consisting of 284 NJ ACTS members were analyzed to summarize the type of researchers on LinkedIn, and their likelihood of responding to LinkedIn marketing campaigns. Efforts to launch a company LinkedIn page and collect followers were completed. Different methods of promotion were evaluated, including direct vs. mass email outreach to over 600+ researchers at Rutgers. Effectiveness of our platform was measured by comparing/overlaying Regulatory website traffic with LinkedIn traffic, as well as tracking the metrics of LinkedIn posts. RESULTS/ANTICIPATED RESULTS: Among 284 NJ ACTS members, 76% (n=215) possess a LinkedIn profile, but only 21% (n=59) are actively interacting with material on LinkedIn, such as creating, commenting, or sharing posts. Among the NJ ACTS LinkedIn users, 27% of individuals (n=57/215) responded to a direct outreach. Retention of the created organizational page was strong, as most users who visited the Regulatory Core page were likely to become followers. Massive email outreach to 600+ researchers within RBHS did not yield a strong LinkedIn following, however it did result in strong signals of website traffic during the days after the promotion was sent. Engagement with posts on LinkedIn can also be amplified and messaging proliferated when colleagues reshare Regulatory posts on their personal feeds. DISCUSSION/SIGNIFICANCE: 3/4 of academic researchers are likely to be on LinkedIn but may not be active users of the platform. The most effective outreach is through direct messaging as opposed to broader, less individualized tactics (including mass email outreach). Evidence suggests potential to utilize LinkedIn to proactively engage in regulatory-related activities.

"Echocardiographic Findings of Covid-19 Patients in Canton Sarajevo During the Third Wave of the Covid-19 Pandemic". Materia Socio Medica 35, n. 4 (2023): 290. http://dx.doi.org/10.5455/msm.2023.35.290-294.
Abstract (sommario):
Background: Increasing evidence indicates that COVID-19 may result in cardiac issues in certain individuals, such as myocarditis, arrhythmias, and heart failure. Ongoing research on echocardiographic manifestations is still limited.Objective: To investigate the incidence and patterns of left and right ventricular dysfunction in COVID-19 patients. Methods: This study retrospectively observed COVID-19 patients admitted to the Clinical Center of University of Sarajevo during the third wave, with a particular focus on cardiac evaluations.Results. Our patients, predominantely male 155 (72.4%), with a mean age of 66.2±11.4, having hypertension 86 (40.1%), diabetes mellitus 61 (28.5%), hyperlipidemia 144 (67.3%), were active smokers 87 (40.6%), had family history of cardiovascular diseases 123 (57.5%) and were COVID-19 positive 95 (44.4%), presented because of chest pain 78 (36.4%), dyspnea 103 (48.1%), palpitations 67 (31.3%), fatigue 106 (49.5%) and peripheral oedema 30 (14.0%). COVID-19 patients reported much higher symptoms of dyspnea (65 (68.4%) vs 38 (31.9%)) and fatigue (73 (76.8%) vs 33 (27.7%)) than COVID-19 negative patients. On the initial laboratory report, COVID-19 patients had a significantly (p<0.05) higher mean score of C-reactive protein (24.0±4.8 vs. 6.0±2.1), D-dimer (1.6±2.5 vs 0.8±0.6), ALT (94.8±17.2 vs 36.5±19.9) and creatinine (128.0±80.8 vs. 93.4±40.1) when compared to COVID-19 negative patients. COVID-19 patients had enlarged left atrium diametes (31.6±5.6 vs 27.5±5.3), enlarged left ventricular diameter both in systole (27.9±18.1 vs 23.3±16.3) and diastole (39.3±24.1 vs 34.9±22.7), reduced left ventricular ejection fraction (53.5±9.2 vs 59.8±4.3) and elevated right ventricular systolic pressure (37.0±16.4 vs 35.1±8.6). Conclusion. COVID-19 patients had enlarged left atrium, enlarged systolic and diastolic left ventricular diameter, reduced left ventricular ejection fraction and elevated right ventricular systolic pressure.

Poole, S. G., M. J. Dooley e D. Rischin. "Calculating carboplatin doses using the 4-variable modification of diet in renal disease (4-v MDRD) estimate of glomerular filtration rate (GFR) in the Calvert formula". Journal of Clinical Oncology 25, n. 18_suppl (20 giugno 2007): 2521. http://dx.doi.org/10.1200/jco.2007.25.18_suppl.2521.
Abstract (sommario):
2521 Background: The dose of carboplatin is usually calculated using the Calvert formula, with various bedside estimates utilized rather than directly measured GFR. The 4-v MDRD equation (Levey AS, et al. Ann Intern Med 2006; 145: 247–254) is now advocated as the routine method of estimating renal function from serum creatinine in all patients. Adoption in clinical practice is occurring despite lack of validation in oncology patients. The aim of this study was to compare carboplatin doses derived from the Calvert formula using measured GFR and the estimates of the 4-v MDRD equation and other established estimates. Methods: GFR was determined using technetium-99m diethyl triamine penta-acetic acid (Tc99mDTPA) clearance. Serum creatinine (Jaffe method) was measured and GFR estimates calculated using 4-v MDRD, Cockcroft and Gault formula (CGF), Wright, Martin, and Jelliffe (JF) formulae. Carboplatin doses were calculated using the Calvert formula, targeting an area under the curve of 7mg.ml- 1.min-1. Results: GFR was measured in 510 adult oncology patients (323 male, 187 female, mean age 63 years, range 17–87 years, mean GFR 84 mL/min, range 16–205 mL/min). The mean (range) carboplatin dose was 765 mg (287–1,610 mg), 681 mg (237–1,306 mg), 674 mg (249–2,044 mg), 721 mg (261–1,536mg), 741 mg (261–2,128mg), 620 mg (244- 1,329 mg) for measured GFR, 4-v MDRD, CGF, Wright, Martin, and JF formulas respectively. The accuracy (% within 20% of ‘true’ dose) was 58%, 63%, 73%, 72% and 49% for 4-v MDRD, CGF, Wright, Martin, and JF formulas respectively. Carboplatin doses derived using the 4-v MDRD estimate of GFR become increasingly less accurate with increasing GFR (see table ). All other formulas performed similarly. Conclusions: The 4-v MDRD equation resulted in an imprecise estimation of carboplatin doses with the degree of variability dependant on the level of renal function.

Abstract (sommario):
Objective: 10-Year survival (10YS) after radical surgery for non-small cell lung cancer (LC) patients (LCP) (T1-4N0-2M0) was analyzed. Methods: We analyzed data of 768 consecutive LCP (age=57.6±8.3 years; tumor size=4.1±2.4 cm) radically operated (R0) and monitored in 1985-2021 (m=660, f=108; upper lobectomies=277, lower lobectomies=177, middle lobectomies=18, bilobectomies=42, pneumonectomies=254, mediastinal lymph node dissection=768; combined procedures with resection of trachea, carina, atrium, aorta, VCS, vena azygos, pericardium, liver, diaphragm, ribs, esophagus=193; only surgery-S=618, adjuvant chemoimmunoradiotherapy-AT=150: CAV/gemzar + cisplatin + thymalin/taktivin + radiotherapy 45-50Gy; T1=320, T2=255, T3=133, T4=60; N0=516, N1=131, N2=121, M0=768; G1=194, G2=243, G3=331; squamous=417, adenocarcinoma=301, large cell=50; early LC=214, invasive LC=554; right LC=412, left LC=356; central=290; peripheral=478. Variables selected for 10YS study were input levels of 45 blood parameters, sex, age, TNMG, cell type, tumor size. Survival curves were estimated by the Kaplan-Meier method. Differences in curves between groups of LCP were evaluated using a log-rank test. Multivariate Cox modeling, analysis, clustering, SEPATH, Monte Carlo, bootstrap and neural networks computing were used to determine any significant dependence. Results: Overall life span (LS) was 2244.9±1750.3 days and cumulative 5-year survival (5YS) reached 72.9%, 10 years – 64.3%, 20 years – 43.1%. 502 LCP lived more than 5 years (LS=3128.7±1536.8 days), 145 LCP – more than 10 years (LS=5068.5±1513.2 days).199 LCP died because of LC (LS=562.7±374.5 days). AT significantly improved 10YS (52.4% vs. 27.7%) (P=0.00002 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 10YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time, weight, color index (P=0.000-0.039). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 10YS and PT early-invasive LC (rank=1), thrombocytes/CC (rank=2), PT N0—N12(rank=3), segmented neutrophils/CC (4), healthy cells/CC (5), lymphocytes/CC (6), erythrocytes/CC (7), stick neutrophils/CC (8), eosinophils/CC (9), leucocytes/CC (10), monocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0). Conclusions: 10-Year survival of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) anthropometric data; 10) surgery type. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Abstract (sommario):
A disc is considered as part of shell of a hallow sphere and used as soil working tool with tillage implement. Detailed information about the effect of disc geometry specially disc diameter with varying concavity is not available. A single disc tool carrier was designed to mount and test the performance of disc of different diameter and concavity. A total of nine discs in the diameter range of 510-610 mm and concavity within 51-95 mm were tested under field conditions for their draft requirement and work performance. The results showed that draft increased consistently with increase in diameter of the disc but the range of variation was low. The draft range in unploughed soil for 510, 560 and 610 mm disc was observed as 177-194,192-204 and 176-227 kg respectively. The increase in draft for higher diameter disc was mainly due to increase in width of cut. Disc concavity showed a pronounced effect on draft. Over the three levels of diameter, the concavity variation of 17,14 and19mm caused draft variations of 14,18 and 43 kg, respectively, in the same order.

"Development of Eco-Friendly Mortars Produced with Kaolin Processing Waste: Durability Behavior Viewpoint". Sustainability 13, n. 20 (15 ottobre 2021): 11395. http://dx.doi.org/10.3390/su132011395.
Abstract (sommario):
This study presents the development of new eco-friendly mortar compositions containing kaolin residues (KR) and assesses their durability behavior. Firstly, the natural and calcinated kaolin residues (600 °C, 650 °C, 700 °C, 750 °C, and 800 °C) were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA), granulometric analysis, and surface area. The kaolin residue calcinated at 800 °C was chosen to be added to new compositions of mortar because it presented the best pozzolanic performance. The aging tests accomplished in internal (Ei) and external (Ee) environments were applied in mortars with a mass proportion of 1:2:6 (cement + KR: lime: sand), in which the KR, calcinated at 800 °C, replaced the cement in the mass fraction of 0%, 5%, 10%, 15%, 20%, and 30%. The Ei was performed for 30, 60, 90, 180, and 360 days, and the Ee for 90; 210; 360; and 512 days. After the aging tests were completed, the mortar compositions containing KR were evaluated to determine their mineralogical phases (XRD), compressive strength (CS), and thermal behavior (DTA and thermogravimetry). In summary, the KR addition to the mortar compositions decreases the mechanical resistance to compression; however, mortars with a substitution of 10% and 20% presented resistance values within the minimum limit of 2.4 MPa established by ASTM C 270.

Abstract (sommario):
ObjectiveTo determine the effect of erenumab, a human anti-calcitonin gene-related peptide receptor monoclonal antibody, in patients with chronic migraine and medication overuse.MethodsIn this double-blind, placebo-controlled study, 667 adults with chronic migraine were randomized (3:2:2) to placebo or erenumab (70 or 140 mg), stratified by region and medication overuse status. Data from patients with baseline medication overuse at baseline were used to assess changes in monthly migraine days, acute migraine-specific medication treatment days, and proportion of patients achieving ≥50% reduction from baseline in monthly migraine days.ResultsOf 667 patients randomized, 41% (n = 274) met medication overuse criteria. In the medication overuse subgroup, erenumab 70 or 140 mg groups had greater reductions than the placebo group at month 3 in monthly migraine days (mean [95% confidence interval] −6.6 [−8.0 to −5.3] and −6.6 [−8.0 to −5.3] vs −3.5 [−4.6 to −2.4]) and acute migraine-specific medication treatment days (−5.4 [−6.5 to −4.4] and −4.9 [−6.0 to −3.8] vs −2.1 [−3.0 to −1.2]). In the placebo and 70 and 140 mg groups, ≥50% reductions in monthly migraine days were achieved by 18%, 36% (odds ratio [95% confidence interval] 2.67 [1.36–5.22]) and 35% (odds ratio 2.51 [1.28–4.94]). These clinical responses paralleled improvements in patient-reported outcomes with a consistent benefit of erenumab across multiple measures of impact, disability, and health-related quality of life. The observed treatment effects were similar in the non–medication overuse subgroup.ConclusionsErenumab reduced migraine frequency and acute migraine-specific medication treatment days in patients with chronic migraine and medication overuse, improving disability and quality of life.Clinicaltrials.gov identifierNCT02066415.Classification of evidenceThis study provides Class II evidence that erenumab reduces monthly migraine days at 3 months in patients with chronic migraine and medication overuse.

Abstract (sommario):
Several times a year companies publish business reports to openly account for their business activities. This thesis examines the effect of those business reports on stock prices of businesses in the German automotive industry. Different statistical methods such as Event Coincidence Analysis and Superposed Epoch Analysis are used to examine possible negative and positive reactions of stock prices before and after the disclosure of business reports. It shows that there seems to be a stronger influence of a negative business report on the daily abnormal rate of return than of a positive business report. Furthermore the thesis confirms the hypothesis of Roeder that the information from a business report is processed not only on the day of publication but also on the day after.

Abstract (sommario):
Horseradish roots, due to the content of many valuable nutrients and substances with healing and pro-health properties, are used more and more in medicine, food industry and cosmetics. In Poland, the cultivation of horseradish is considered minor crops. In addition, its limited size causes horseradish producers to encounter a number of unresolved agrotechnical problems. Infectious diseases developing on the leaves and roots during the long growing season reduce the size and quality of root crops. The small range of protection products intended for use in the cultivation of horseradish generates further serious environmental problems (immunization of pathogens, low effectiveness, deterioration of the quality of raw materials intended for industry, destruction of beneficial organisms and biodiversity). In order to meet the problems encountered by horseradish producers and taking into account the lack of data on: yielding, occurrence of infectious diseases and the possibility of combating them with methods alternative to chemical ones in the years 2012–2015, rigorous experiments have been carried out. The paper compares the impact of chemical protection and its reduced variants with biological protection on: total yield of horseradish roots and its structure. The intensification of infectious diseases on horseradish leaves and roots was analyzed extensively. Correlations were examined between individual disease entities and total yield and separated root fractions. A very important and innovative part of the work was to learn about the microbial communities involved in the epidemiology of Verticillium wilt of horseradish roots. The effect was examined of treatment of horseradish cuttings with a biological preparation (Pythium oligandrum), a chemical preparation (thiophanate-methyl), and the Kelpak SL biostimulator (auxins and cytokinins from the Ecklonia maxima algae) on the quantitative and qualitative changes occurring in the communities of these microorganisms. The affiliation of species to groups of frequencies was arranged hierarchically, and the biodiversity of these communities was expressed by the following indicators: Simpson index, Shannon–Wiener index, Shannon evenness index and species richness index. Correlations were assessed between the number of communities, indicators of their biodiversity and intensification of Verticillium wilt of horseradish roots. It was shown that the total yield of horseradish roots was on average 126 dt · ha–1. Within its structure, the main root was 56%, whereas the fraction of lateral roots (cuttings) with a length of more than 20 cm accounted for 26%, and those shorter than 20 cm for 12%, with unprofitable yield (waste) of 6%. In the years with higher humidity, the total root yield was higher than in the dry seasons by around 51 dt · ha–1 on average. On the other hand, the applied protection treatments significantly increased the total yield of horseradish roots from 4,6 to 45,3 dt · ha–1 and the share of fractions of more than 30 cm therein. Higher yielding effects were obtained in variants with a reduced amount of foliar application of fungicides at the expense of introducing biopreparations and biostimulators (R1, R2, R3) and in chemical protection (Ch) than in biological protection (B1, B2) and with the limitation of treatments only to the treatment of cuttings. The largest increments can be expected after treating the seedlings with Topsin M 500 SC and spraying the leaves: 1 × Amistar Opti 480 SC, 1 × Polyversum WP, 1 × Timorex Gold 24 EC and three times with biostimulators (2 × Kelpak SL + 1 × Tytanit). In the perspective of the increasing water deficit, among the biological protection methods, the (B2) variant with the treatment of seedlings with auxins and cytokinins contained in the E. maxima algae extract is more recommended than (B1) involving the use of P. oligandrum spores. White rust was the biggest threat on horseradish plantations, whereas the following occurred to a lesser extent: Phoma leaf spot, Cylindrosporium disease, Alternaria black spot and Verticillium wilt. In turn, on the surface of the roots it was dry root rot and inside – Verticillium wilt of horseradish roots. The best health of the leaves and roots was ensured by full chemical protection (cuttings treatment + 6 foliar applications). A similar effect of protection against Albugo candida and Pyrenopeziza brassicae was achieved in the case of reduced chemical protection to one foliar treatment with synthetic fungicide, two treatments with biological preparations (Polyversum WP and Timorex Gold 24 EC) and three treatments with biostimulators (2 × Kelpak SL, 1 × Tytanit). On the other hand, the level of limitation of root diseases comparable with chemical protection was ensured by its reduced variants R3 and R2, and in the case of dry root rot, also both variants of biological protection. In the dry years, over 60% of the roots showed symptoms of Verticillium wilt, and its main culprits are Verticillium dahliae (37.4%), Globisporangium irregulare (7.2%), Ilyonectria destructans (7.0%), Fusarium acuminatum (6.7%), Rhizoctonia solani (6.0%), Epicoccum nigrum (5.4%), Alternaria brassicae (5.17%). The Kelpak SL biostimulator and the Polyversum WP biological preparation contributed to the increased biodiversity of microbial communities associated with Verticillium wilt of horseradish roots. In turn, along with its increase, the intensification of the disease symptoms decreased. There was a significant correlation between the richness of species in the communities of microbial isolates and the intensification of Verticillium wilt of horseradish roots. Each additional species of microorganism contributed to the reduction of disease intensification by 1,19%.

In Les parlers urbains africains au prisme du plurilinguisme : description sociolinguistique, 281–303. Observatoire européen du plurilinguisme, 2020. http://dx.doi.org/10.3917/oep.kosso.2020.01.0281.
Abstract (sommario):
Le nouchi, ou mélange de langue, traité d’ “argot abidjanais” au début des années 80 (Kouadio, 1992 :178) s’est imposé progressivement comme style d’expression populaire en Côte d’Ivoire. Dans sa pratique, cette variété est diversement interprétée par les chercheurs. Pour les uns, c’est le signe de l’appropriation réussie du français par les locuteurs ivoiriens (Aboa, 2011 : 53). Pour d’autres, le nouchi est la volonté de reconnaissance, d’identification de certains jeunes (Lafage 2002 ; 35 ; Kouadio, 2008) qui le revendiquent comme moyen d’affirmation de leur esprit créateur et de leur volonté de liberté et d’autonomie (Cissé, 2015). En marge de ces différentes prises de positions théoriques qui rendent compte de sa mutation, le nouchi reste encore attaché à son statut marginal, servant de codes et de tactiques criminelles aux rebuts sociaux et autres déviants pour couvrir leurs activités criminelles, alimentant ainsi l’insécurité urbaine. C’est le cas pour le trafic de drogues. Une criminalité en pleine expansion à Abidjan qui résiste aux politiques et actions de lutte informelles et Etatiques (MDM, 2014 ; RAIDH, 2015 ; DPSD, 2016) et dont les acteurs sont fortement imprégnés de cette technique d’expression. L’objectif de cet article est de montrer l’incidence du nouchi sur la lutte contre le trafic de drogues à Abidjan. Au plan méthodologique, l’étude s’est déroulée à Abidjan dans le quartier d’Adjamé, centre commercial qui regorge des fumoirs et des marchés de drogues et à Yopougon wassakara. Elle a porté sur 60 enquêtés composés de trafiquants de drogues (33), de sujets parlant le nouchi (05), des agents des forces de l’ordre (15), des commerçants de médicaments prohibés, des usagers (07), choisis à partir d’un échantillonnage en boule de neige. Il s’est agi d’identifier les expressions utilisées par les acteurs du trafic de drogues, d’en saisir les sens et d’appréhender leurs rôles dans le développement des trafics. A travers ses codes, expressions et symboles, à la fois variés, diversifiés et polysémiques, le nouchi sert de tactiques criminelle aux délinquants. Il contribue d’une part à dissimuler les activités de vente, tromper la vigilance des acteurs sociaux et réduire les risques d’interpellation et de saisies des drogues. D’autre part, à travers des appellations qui vantent les effets des produits, il favorise l’usage des drogues et l’état de toxicomanie.

Abstract (sommario):
An efficient method for allylation of a sterically hindered alcohol in the presence of base-sensitive functionality (cf. 1 to 2) has been developed (Tetrahedron Lett. 2012, 53, 1319) by Richard B. Silverman at Northwestern University. Mark S. Taylor at the University of Toronto found (J. Am. Chem. Soc. 2012, 134, 8260) that borinic acid 4 catalyzed the monofunctionalization of diols and carbohydrates such as 3. The selective functionalization of unprotected peptides can be challenging, but Man-Kin Wong at Hong Kong Polytechnic University and Chi-Ming Che at the University of Hong Kong have shown (J. Am. Chem. Soc. 2012, 134, 2589) that selective N-terminal functionalization can be achieved with the alkynyl ketene 7, which allows for subsequent derivitization of the acylated products (e.g., 8) via click reactions with azides. To formylate amines such as morpholine (9), an N-heterocyclic carbene (e.g., 10) catalyzed procedure that utilizes CO2 and polymethylhydrosiloxane (PMHS) has been developed (J. Am. Chem. Soc. 2012, 134, 2934) by Thibault Cantat at the CEA in France. For the protection of acyclic amino acid derivatives, Eiji Tayama at Niigata University has reported (Tetrahedron Lett. 2012, 53, 1373) a new protecting group, 1,2-dimethoxy-4,5-dimethylene, that is installed by double alkylation and can be removed with, for example, ethyl chloroformate to produce the corresponding carbamate (e.g., 12 to 13). As far as protecting groups go, ethers can be especially challenging to remove; however, a new procedure for the oxidative cleavage of glycol ethers, including dioxane, has been developed (Org. Lett. 2012, 14, 3218) by Zhong-Quan Liu at Lanzhou University. This copper-catalyzed procedure employs carboxylic acids such as 14 and produces alkoxymethoxy esters 15. The cleavage of unactivated ethers such as dibutyl ether as a means to alkylate sulfonamides (cf. 16) has been reported (Synlett 2012, 595) by Wei Zeng at South China University of Technology. Protecting groups that are thermally labile offer the ability to achieve deprotection without added reagents. A new thermolabile protecting group has been developed (Tetrahedron Lett. 2012, 53, 666) by Marcin K. Chmielewski at the Polish Academy of Sciences based on 2-pyridyl-N-(2,4-difluorobenzyl)aminoethyl carbonates.

Abstract (sommario):
Abstract β-Toxins are responsible for the life hazard constituted, in Central and South America, by scorpion stings. They are qualitatively and quantitatively the most important polypeptides of the venom. They are made of one single polypeptide chain of 60 to 66 amino acid residues crosslinked by four disulfide bridges (Possani et al. 1981; Bechis et al. 1984; Martin-Eauclaire et al. 1987; Ceard et al. 1992; Zamudio et al. 1992). The structure of variant 3 from Centruroides sculpturatus Ewing has been deter¬ mined at high resolution by X-ray crystallography (Fontecilla-Camps et al. 1980). This protein although poorly active on mouse has an amino acid sequence very close to that of the most potent β-toxins: it shows a common structure made up of one a-helix and one triple stranded β-sheet maintained in position by two conserved disulfide bridges (Cys-25 and Cys-51, Cys-29 and Cys-53). Two more disulfide bridges link in one hand loops protruding from this region (Cys-16 and Cys-41) and, on the other hand, the (-terminal end of the chain to the N-terminal region (Cys-12 and Cys-72). On one side of the molecule, a hydrophobic surface exists, which has been implicated in the high affinity binding of β-toxins to their pharmacological target (Fontecilla-Camps et al. 1980). β-Toxins were defined as those toxins which behave like toxin II of Centruroides Suffusus suffusus (Css II): they bind to site 4 of the voltage-dependent sodium channel present in rat brain synaptosomes (Jover et al. 1980) modifying the activation process and inducing repetitive firing on frog myelinated nerve on voltageclamp conditions (Couraud et al. 1982; Martin-Eauclaire and Couraud 1995).

Abstract (sommario):
La participation citoyenne, nommée également engagement citoyen (Pattie et al., 2003), est une sous-catégorie du concept plus large de participation sociale (Misztal, 1977). En sciences sociales, elle apparait comme une dimension incontournable pour analyser la société civile. L’objectif de cet article est de tenter de répondre à trois questions principales : 1. Quel est le niveau général de participation citoyenne de la population habitant dans les zones rurales en Pologne et en France à la fin de a deuxième décennie du XXIe siècle et quelle est l’ampleur des variations de participation entre ces deux pays ? 2. Quels modèles de participation citoyenne dominent dans les populations des zones rurales en Pologne et en France ? 3. Lequel des modèles suivants visant à expliquer la variation de la participation citoyenne (le modèle du statut socio-économique, le modèle du capital social ou le modèle de l’attachement) convient le mieux pour expliquer la variation de la participation de la population européenne. Des données issues de la neuvième édition de l’Enquête sociale européenne menée dans 29 pays européens en 2018, auprès de 49 519 participants permettront de répondre à ces questions. Seules les données concernant 1352 personnes vivant dans des zones rurales en Pologne (664 individus) et en France (688 individus) ont été utilisées dans le cadre de notre analyse.

Abstract (sommario):
Energy is one of the most basic parts of the framework, and very essential for the national growth and economic development, of any country. The sustainable new sources of energy reproduction from traditional mediums like coal, lignite, petroleum, hydro, and nuclear capacity to non-traditional medium like wind, solar, agriculture, and home waste. Energy interest in the nation was prolonged very fast and is relied upon to rise further in the years to come. To fulfill the expanding need for energy, solar- or sun-based energy will play a real job in helping to this interest. The current scenario indicates that 60 GW of conventional power/energy capacity has been add over the last three years, which is believed to be the highest addition so far. As of April 2021, India has a thermal installed ability of 234 GW, and 53% of the part is covered by coal, diesel, and natural gas. The private sector produces 47.4% of thermal energy, although states and centres generate 27.1% and 25.5% individually. As of now, solar energy in India is exceptionally good.

Abstract (sommario):
Abstract In BICS 18 (1971), 53-68 Mr Peter Parsons published with a commentary a new fragment of a Greek satirical novel, which will now appear as P. Oxy. 30m; further valuable work on the papyrus by Professor Merkel bach came out in ,?,PE 11 (1973), 81-rno. From these discussions the following plot emerges. At the beginning someone learns arcane knowledge from a gallus, which he is to teach in his turn to a certain Iolaus. He then does so. His teaching is a catalogue of what he knows, which seems to comprise both information about what Iola us has done or intends to do and revelations granted to the speaker as an initiate. _In this catalogue are found (line 29) the word ava-\vow q,aa,v, followed by the letters Ka1ToK01TTJP,, which, as Mr Parsons suggests (art. cit. 60), may refer to the a1ToK01T or self-mutilation of the galli. This note concerns the interpretation of ava-\va,v <f,aa,v.

Abstract (sommario):
Matthias Beller of the Universität Rostock developed (Angew. Chem. Int. Ed. 2014, 53, 6477) a Rh catalyst for the acceptorless dehydrogenation of an alkane 1 to the alkene 2. Bhisma K. Patel of the Indian Institute of Technology Guwahati effected (Org. Lett. 2014, 16, 3086) oxidation of cyclohexane 3 and 4 to form the allylic benzoate 5. Justin Du Bois of Stanford University devised (Chem. Sci. 2014, 5, 656) an organocatalyst that mediated the hydroxylation of 6 to 7. Vladimir Gevorgyan of the University of Illinois, Chicago hydrosilylated (Nature Chem. 2014, 6, 122) 8 to give an intermediate that, after Ir-catalyzed intramolecular C–H functionalization followed by oxidation, was converted to the diacetate 9. Sukbok Chang of KAIST used (J. Am. Chem. Soc. 2014, 136, 4141) the methoxime of 10 to direct selective amination of the adjacent methyl group, leading to 11. John F. Hartwig of the University of California, Berkeley effected (J. Am. Chem. Soc. 2014, 136, 2555) diastereoselective Cu-catalyzed amination of 12 with 13 to make 14. David W. C. MacMillan of Princeton University accomplished (J. Am. Chem. Soc. 2014, 136, 6858) β-alkylation of the aldehyde 15 with acrylonitrile 16 to give 17. Yunyang Wei of the Nanjing University of Science and Technology alkenylated (Chem. Sci. 2014, 5, 2379) cyclohexane 3 with the styrene 18, leading to 19. Bin Wu of the Kunming Institute of Botany described (Org. Lett. 2014, 16, 480) the Pd-mediated cyclization of 20 to 21. Similar results using Cu catalysis were reported (Angew. Chem. Int. Ed. 2014, 53, 3496, 3706) by Yoichiro Kuninobu and Motomu Kanai of the University of Tokyo and by Haibo Ge of IUPUI. Jin-Quan Yu of Scripps La Jolla constructed (J. Am. Chem. Soc. 2014, 136, 5267) the lactam 24 by γ-alkenylation of the amide 22 with 23, followed by cyclization. Philippe Dauban of CNRS Gif-sur-Yvette prepared (Eur. J. Org. Chem. 2014, 66) the useful crystalline chiron 27 by asymmetric amination of the enol triflate 26 with 25. Matthew J. Gaunt of the University of Cambridge showed (J. Am. Chem.

Abstract (sommario):
Huanfeng Jiang at the South China University of Technology developed (J. Am. Chem. Soc. 2013, 135, 5286) the palladium-catalyzed dehydrogenative aminohalogenation of methyl acrylate with aniline 1. A 1,3-hydrogen shift/ chlorination catalyzed by an iridium complex was reported (Angew. Chem. Int. Ed. 2013, 52, 6273) by Belén Martín- Matute at Stockholm University. Robert M. Waymouth discovered (J. Am. Chem. Soc. 2013, 135, 7593) the chemoselective oxidation of polyol 5 by a cationic palladium species. A ruthenium(II) hydride was found to catalyze the conversion of alcohols such as 7 to carboxylic acids using water as the oxygen source as disclosed (Nature Chem. 2013, 5, 122) by David Milstein at the Weizmann Institute of Science in Israel. Susan K. Hanson at the Los Alamos National Laboratory in New Mexico reported (Org. Lett. 2013, 15, 650) the acceptorless dehydrogenation of alcohols catalyzed by cobalt complex 12 to form imines such as 13 upon reaction with an amine. A collaboration led by Pedro J. Pérez at the University of Huelva in Spain studied (J. Am. Chem. Soc. 2013, 135, 3887) the oxidation of alkanes under catalysis with copper complex 15, primarily yielding alcohols and ketones, such as in the conversion of cyclohexane (14) to cyclohexanol (16) and cyclohexanone (17). A remarkable symmetry-breaking Wacker oxidation of diene 18 to produce 19 was the key step in the total synthesis of (+)-obolactone reported (Org. Lett. 2013, 15, 1294) by Reinhard Brückner at the University of Freiburg in Germany. Kiyotomi Kaneda at the University of Osaka found (Angew. Chem. Int.

Abstract (sommario):
This paper describes a novel, non-intrusive thermal imaging system based on the fluorescence properties of an europium-doped lanthanum oxysulfide (Eu+3:La2O2S) thermographic phosphor. In this system the phosphor coating on a test surface is excited by a pulsed Nd:YAG laser. The resulting fluorescent emission of the temperature-sensitive 512 nm transition, along with that of the relatively temperature independent 620 nm transition, is acquired using an image-intensified charged coupled device (ICCD) camera. The ratio of the 512- and 620-nm emissions, integrated over a set gating period, is then correlated with temperature. Quality data obtained from a calibration procedure have demonstrated that the present approach can be more advantageous than many existing thermal imaging techniques. The system has been specifically designed to provide two-dimensional temperature measurements with high accuracy and exceptional spatial resolution. Because of the extremely short fluorescent lifetimes of various thermographic phosphors (∼μs), applicability of the technique to fast-moving or rotating surfaces is very promising.

Abstract (sommario):
Nationwide surveys of hereditary platelet function disorders in Japan were carried out in 1976, 1981, and 1986. Information on 271 cases received in the 1986 survey was analyzed with that for 103 other cases reported in earlier surveys but not in 1986, making a total of 374 cases. The mortality rate was 6.8% of 162 cases in 1976, 6.6% of 213 cases in 1981, and 5.9% of 374 cases in 1986. Bleeding symptoms appeared at age 12 years in 56.8% of patients and the most common were epistaxis and purpura. Of the 295 cases 49.5% were isolated cases, 20.3% had siblings with confirmed bleeding tendencies, and 30.2% had other kin with bleeding tendencies, suggestings autosomal tnansmission. Consanguineous marriage was reported by 11.9% of patients.Of the 374 cases in 1986, 59.4% were thrombasthenia (TA), 11.5% Bernard-Soulier symdrome (BSS), 22.5% release abnormalities (PRA), 1.3% other, and 5.3% unclassified. Of the 84 cases of PRA, 60 were storage pool deficiency, 18 release mechanism abnormalities, and 6 undecided between the two types. The resultsof laboratory tests were as follows .

Abstract (sommario):
Introdução: Segundo a OMS temos cerca de 6 milhões de indivíduos infectados pelo parasito Trypanosoma cruzi no mundo. O mecanismo de transmissão vetorial continua sendo de grande importância na epidemiologia da doença, sendo, portanto, o alvo dos programas de controle. No Brasil observou-se uma notável diminuição de novos casos da infecção após a implementação das campanhas de controle vetorial. Objetivo: Avaliar a vigilância entomológica da DCh nos municípios da jurisdição da Superintendência Regional de Saúde de Governador Valadares (SRS/GV) nos anos de 2014 a 2019. Métodos: A área estudada corresponde a 51 municípios da mesorregião do Vale do Rio Doce, no Leste de Minas Gerais. Os dados foram disponibilizados pelo laboratório de referência em entomologia da SRS/GV. Os insetos capturados pelos moradores e enviados foram avaliados quanto ao hábito alimentar, estádio evolutivo, local de captura, espécie do triatomíneo e presença ou ausência de infecção pelo T. cruzi. Resultados: Foram encaminhados à SRS/GV 1.704 insetos, sendo 1.491 hematófagos, 107 fitófagos e 99 predadores. Avaliando os insetos hematófagos quanto ao estádio evolutivo constatou-se que 1.425 (95,6%) eram adultos e 66 (4,4%) eram ninfas, sendo a maioria capturados no intradomicílio (1.083/1.491). Foram examinados 1.225 insetos, sendo constatado a infecção pelo T. cruzi em 514 exemplares, revelando assim uma taxa de infecção natural de 42%. Dentre os insetos infectados, 407 (79,5%) exemplares foram capturados no intradomicílio, 96 (18,5%) no peridomicílio e 11 (2%) em locais não identificados. As seguintes espécies de triatomíneos foram identificadas na região: Triatoma vitticeps (936), Panstrongylus megistus (284), Panstrongylus diasi (244), Rhodnius neglectus (11) e Panstrongylus geniculatus (1). Foi constatado a presença de triatomíneos infectados em 46 municípios, com destaque para Conselheiro Pena (64), Tarumirim (48), Sobrália (46), Capitão Andrade (44), Itanhomi (36) e José Raydan (30). Conclusão: Os dados nos permitem afirmar que T. vitticeps é a espécie predominante na região, sendo capturados frequentemente insetos adultos no intradomicílio e com consideráveis taxas de infecção natural pelo T. cruzi. Vale ressaltar ainda o encontro de ninfas no intradomicílio que caracteriza um processo de colonização e reforça a necessidade de aprimoramento das ações de vigilância entomológica na região atendida pela SRS/GV.

Abstract (sommario):
Abstract. Solid waste management is the biggest challenge due to population growth. Lack of awareness about onsite processing of solid waste implies production of huge quantity of solid waste which is unmanageable. In this study an attempt is made to utilize the degraded solid waste called compost which is collected from municipal site and is used as a filler material in concrete. Compost is replaced for fine aggregate with 5%, 10%, 15% and 20% in conventional concrete. The compressive strength results at the age of 28 days are 30.5, 19.8, 16.8 and 18.2 N/mm2 respectively. Result indicates 5% replacement of compost is effective in concrete. The concrete specimen made with compost (CVC) and conventional concrete (CC) are exposed to an elevated temperature of 200°C, 400°C, 600°C and 800°C respectively. Result indicates the conventional concrete shows 5.3%, 6.1%, 15% and 24% compressive strength loss whereas 5% compost replaced specimen shows 10%, 11 %, 23.2% and 58.2% respectively. At an elevated temperature, both conventional concrete and compost-based concrete lost its strength. The reason could be thermal incompatibility between the aggregates and concrete. However, the loss of compressive strength is almost double in CVC than CC. The possible reason could be volatile compounds may evaporate in CVC at high temperature. The weight lost is observed in CC varies from 2.4 % to 4.5 % whereas CVC shows 6% to 7% from 200°C to 800°C. Weight lost is 3% more in CVC specimen than CC specimen.

Abstract (sommario):
Abstract Plasma generated by an SG-100 torch was applied to a spray suspension formulated with the use of ZrO2+8 wt% Y2O3 (8YSZ) solid phase. The solids had a mean size of about 4.5 μm and were obtained by milling of commercial Metco 204 NS powder. The suspension was formulated with 20 wt% solid phase, 40 wt% water and 40 wt% ethanol. The plasma spray parameters were optimized with the electric power equal to 40 kW, working gases composition Ar 45 slpm and H2 5 slpm, spray distance varying from 40 to 60 mm, and torch scan linear speed varying from 300 to 500 mm/s. Coatings with thicknesses ranging from 51 to 106 μm were sprayed onto stainless steel substrates. The porosity of the samples was found from the image analysis of metallographically prepared cross-sections of the samples to be in the range of 8 to 12%. Thermal diffusivity was measured with the use of the commercial NanoFlash system in the temperature range from room temperature to 523 K. The measurements were made with the use of the coatings sprayed on the substrate, and a 2-layer numerical model was developed to determine thermal diffusivity of the coatings. The diffusivity was in the range from 0.196 × 10-6 to 0.352 × 10-6 m2/s in room temperature depending on the spray parameters. The obtained data were then associated with the literature data of density and specific heat and experimental porosity to find thermal conductivity, which was in the range of 0.47 to 0.86 W/(mK) at room temperature, depending on the spray run.

Abstract (sommario):
Previous immunochemical studies have demonstrated that the introduction of a chain crosslinks by Factor XIII begins immediately after fibrin aggregation. While there area data to indicate that regions Aα #241-476 and Aα #518-584 are specifically involved in this early crosslinking process, identification of the exact glutamine and lysine residues that participate in the reaction remains to be determined. In this study monoclonal antibodies, whose specificity for these two regions has been defined (anti-Aα #259-276, F-105; anti-Aα #540-554, F-102), were used to isolate preparations of partially degraded fibrinogen molecules which could then be characterized for C00H-terminal Aα chain heterogeneity and crosslinking capacity to obtain a more precise localization of residues involved in early crosslinking. In order to assess the relative contribution of sites within the COOH-terminal region that includes 1 potential GLN at Aα #565 and 4 potential LYS at Aα #556, 562, 580 and 585, fibrinogen molecules that were missing these residues were isolated from preparations of purified fibrinogen using F-102-Sepharose immuno-affinity adsorption. Characterization of the partially degraded material (i.e., non-binding) by Western Blotting using F-102 and F-105 confirmed the presence of Aα remnants (29K-66K) that shared the structure Aα #1-276 but differed in the extent to which regions between ∼#276 and ∼#559 were preserved. When the crosslinking capacity of these partially degraded molecules was examined, using Western Blotting to monitor the appearance of crosslinked a chains during in vitro clotting, effective formation of early crosslinked species ( ∼100K, ∼ 200K) as well as eventual accumulation of a polymers, could be demonstrated. These findings indicate that at least one early a chain crosslink involves activity on the part of LYS and GLN residues located proximal to Aα #540. While these data do not rule out the existence of additional crosslinking sites situated more distally (i.e., within Aα #540-584), they do indicate that degraded fibrinogen molecules, circulating under pathophysiologic conditions, may undergo adequate fibrin stabilization despite a loss of at least 70 COOH-terminal Aα chain residues.

In AM-EPRI 2016, a cura di J. Parker, J. Shingledecker e J. Siefert. ASM International, 2016. http://dx.doi.org/10.31399/asm.cp.am-epri-2016p0125.
Abstract (sommario):
Abstract The reasonable procedures for estimation of 100,000 h creep rupture strength have been investigated for Alloy 617 and Alloy 740 for A-USC power plants by Larson Miller method. The creep rupture data of longer duration than 500 h in the temperature range between 593 and 816 °C and between 600 and 850 °C were used for the analysis on Alloy 617 and Alloy 740, respectively. The data were obtained by Special Metals. In these temperature ranges, Ni3Al-γ’ can precipitate in Alloy 617 and Alloy 740 during creep. The maximum time to rupture was 40,126.7 and 24,066 h for Alloy 617 and Alloy 740, respectively. The rupture data for Alloy 617 exhibit large scattering, especially at 760 °C, showing a split into two groups. After eliminating the shorter time to rupture data at 760 °C, the regression analysis using the second order equation of Larson-Miller parameter gives us the Larson-Miller constant C of 12.70 and the 100,000 h creep rupture strength of 100 MPa at 700 °C. The regression analysis underestimates the constant C and corresponding 100,000 h creep rupture strength of Alloy 617, as shown by the regression curves locating below the rupture data at long times, while those locating above the rupture data at short times. The underestimation of constant C is caused by large data scattering. The linear extrapolation of log tr versus reciprocal temperature 1/T plot to 1/T = 0 at constant stresses gives us the constant C of 18.5, which is much larger than that by the regression analysis. Using an appropriate constant C of 18.45, the 100,000 h creep rupture strength of Alloy 617 is estimated to be 123 MPa at 700 °C. On the other hand, the rupture data for Alloy 740 exhibit only a little bit scattering. The regression analysis gives us C = 18.45, which agrees very well with that by the linear extrapolation of log tr versus 1/T plot to 1/T = 0. The 100,000 h creep rupture strength of Alloy 740 is estimated to be 214 and 109 MPa at 700 and 760 °C, respectively.

Abstract (sommario):
Solar thermal power plants are a promising option for future solar electricity generation. Their main advantage is the possibility to utilize integrated thermal storage capacities, allowing electricity generation on demand. In state of the art solar thermal power plants, two-tank molten-salt thermal energy storages are used. Significant cost reductions are expected by using thermocline thermal energy storage by storing the liquid storage material inside a single tank when compared to a two tank storage system. By embedding a low cost solid filler material inside the storage tank further cost reductions can be achieved. In earlier studies [1, 2] several potential filler materials have been investigated. In these study quartzite turned out to be a promising candidate due to its satisfying thermal stability and availability. At a temperature of approx. 573°C the crystal structure of quartzite changes from trigonal α-quartz phase to the hexagonal β-quartz phase [3]. This quartz conversion results in a volume change [4] that may cause cracking of the quartzite crystals due to weight loads in a packed bed. Since these thermal tests of the study mentioned were limited to 500°C this dunting was not considered. Thus, despite of the published studies there is a need for further, more detailed analysis. One trend in today’s development of solar thermal power plants is to use molten salt as storage material and heat transfer fluid at operating temperatures of 560°C and above. Accordingly, the quartz inversion might limit the applicability of quartzite as a filler material at elevated operating temperatures. Due to this concern, an investigation has been started to investigate the utilizability of natural rocks as low cost filler materials. In the first phase of this investigation a comprehensive literature survey was conducted. Based on this study, magmatic and sedimentary rocks turned out to the most promising rock classes for this application. For the further investigation, basalt was chosen as a suited representative for magmatic and quartzite for sedimentary rocks. In lab-scale tests, these candidate materials were investigated with respect to their: • Calcite content • Thermal stability up to 900°C in air • Thermal stability up to 560°C in molten salt • Cyclic stability between 290°C and 560°C in molten salt • Specific heat capacity up to 600°C In this paper the results of these investigations are presented and future activities are outlined.

Abstract (sommario):
The May 2016 surveys of expectations conducted by Central Banks with inflation targeting regimes indicate that simple average growth expectations for 2016 for the eight countries covered by REVELA have remained constant at 1.7% compared to the previous month. Similarly, the GDP weighted average growth expectations remained stable at -0.7%. Also inflation expectations for 2016 remained stable in May compared to previous month both on the simple average basis at 5.3% and on the GDP weighted average basis at 5.5%. At the individual country level, growth expectations remained constant in six countries: Guatemala at 3.7%, Paraguay at 3.0%, Colombia at 2.9%, Mexico at 2.4%, Chile at 1.7% and Uruguay at 0.3% and decreased by 0.1% in both Brazil and Peru. Inflation expectations fell in Mexico by 0.1%, remained constant in Uruguay at 10.1%, in Colombia at 6.0%, in Paraguay at 4.8%, and in Chile and Peru at 3.5%. Finally, they increased in Paraguay by 0.2% and in Brazil and Guatemala by 0.1% in both countries. Expected growth for the region is as low as -3.9% for Brazil and as high as 3.7% in Guatemala, while expected inflation ranges from 3.1% in Mexico to 10.1% in Uruguay.

Abstract (sommario):
In this study, we examine potential temporal changes in coda Q values for two significant Canadian earthquakes in different tectonic environments: the 2017 (Mw 5.9) Barrow Strait earthquake along Canada's northern margin and the 2012 (Mw 7.8) Haida Gwaii subduction earthquake on Canada's west coast. Waveforms from 124 earthquakes (2.0 &lt;/= M &lt;/= 4.6) for ~30 years prior to the January 8, 2017 Barrow Strait earthquake and 66 events (mainly aftershocks of M 2.0-5.3) in about 4 years after the mainshock recorded by the closest seismic station (RES) of the Canadian National Seismograph Network (CNSN) were utilized in this study. Based on our analysis, overall average of Q0 (Q at 1 Hz) decreased from 92 (before the mainshock) to 81. The most significant decrease in the frequency range between 2 and 16 Hz is observed for areas corresponding to ellipse parameter a2 of 50, 70 and 80 mainly related to aftershock activity. Precursory Q changes could not be evaluated before the mainshock due to the lack of reported seismicity within 100 km of the recording seismic station for almost 2 years from April 2015 to January 2017. Coda Q values before and after the October 28, 2012 Haida Gwaii earthquake in British Columbia show a similar pattern. Waveforms from 249 earthquakes (2.0 &lt;/= M &lt;/= 4.9) in 2 years before the mainshock and 498 events (2.5 &lt;/= M &lt;/= 6.3) in 2 years after the mainshock recorded by the three closest seismic stations of the CNSN were utilized. Overall average of Q0 decreased from 89 (before the mainshock) to 69 (station BNB), from 90 to 79 (station DIB) and from 86 to 78 (station VIB). In general, these results are in agreement with other global studies that show a decrease in Q0 following a major earthquake, likely the result of increased fracturing and fluids in the epicentral region.

Tapia, Carlos, Nora Sanchez Gassen e Anna Lundgren. In all fairness: perceptions of climate policies and the green transition in the Nordic Region. Nordregio, maggio 2023. http://dx.doi.org/10.6027/r2023:5.1403-2503.
Abstract (sommario):
The survey presented in this report reveals that Nordic citizens are concerned about climate change. Many people are willing to increase efforts to fight climate change, even if this entails a personal contribution in terms of higher taxes or behavioural change. The survey shows that different social groups perceive the impacts of climate change and climate mitigation policies in different ways. In general, attitudes towards climate policies and perceptions regarding their fairness are conditioned by socio-demographic factors such as gender, age, employment status, type of housing and transport behaviour. General attitudes towards climate change and climate policies The first part of this report explores general attitudes towards climate change and climate policies. This section shows that seven in ten (71%) respondents think that climate change is a serious or very serious problem, particularly among the youngest age group (18-29 years). Three in four (74%) interviewed persons in this group share this view. Those with a university degree are more concerned about climate change (83%) than those with primary or secondary education (57% and 62%, respectively). Approximately half (48-51%) of respondents in all age groups agree that more financial resources should be invested in preventing climate change, even if this would imply an increase in taxes. The survey results show that women in the Nordic Region are more concerned about climate change than men (79% compared to 64%). It also reveals that people living in urban areas are more worried about climate change (82%) than those who live in towns and suburbs (68%) or in rural areas (62%). Urban dwellers are also more positive about investing more resources in preventing climate change (59%) than those who live in rural areas (39%) and in towns and suburbs (46%). More than half of the respondents (52%) agree that taking further action on climate change would be beneficial for the economy. Students, unemployed and retired people are more likely to agree with this view (55%, 57% and 55%, respectively) than those currently in employment, including the self-employed (50%). Those employed in carbon-intensive sectors are less positive about the expected economic impact of climate policies than those who work in other economic sectors (41% compared to 55%). They are also more concerned about the risk of job losses during the transition to a low-carbon economy than those employed in sectors with lower carbon intensity (37% compared to 24%). Concerns about this issue are also higher among those who live in rural areas (31%) or towns and suburbs (30%) compared to those who live in cities (22%). Present and future effects of climate change mitigation policies on individuals and households The central part of the survey explores perceptions regarding the present and future impacts of climate policies. Such challenges are perceived differently depending on specific sociodemographic conditions. Nearly one fourth (23%) of respondents state that high energy costs mean they are struggling to keep their homes at a comfortable temperature. Those living in houses report being more impacted (27%) than those living in apartments (18%), and those using fossil fuels to heat their homes are most affected (44%). The risk of energy poverty is also higher among non-EU immigrants to the Nordic Region. Those who say they are struggling to keep their homes at a comfortable temperature range from 23% among Nordic-born citizens to 37% among non-EU immigrants. Nearly three in ten respondents (28%) have modified their transportation behaviour during the last year due to high fuel costs. This proportion is substantially greater among those living in towns and suburbs (32%) compared to those who live in rural areas (29%) or cities (23%). The majority of the Nordic population (52%) states that current climate policies have a neutral effect on their household economies. However, 28% of respondents say they are negatively impacted by climate policies in economic terms. Men report being negatively affected more frequently than women (33% vs 22%, respectively). People who live in houses are more likely to claim they are being negatively impacted than people who live in apartments (31% and 23%, respectively). Nearly half (45%) of the respondents in the Nordic Region agree that climate initiatives will improve health and well-being, and half of the respondents (50%) think that climate change initiatives will lead to more sustainable lifestyles in their area. However, half (51%) of the Nordic population expect to see increases in prices and the cost of living as a consequence of climate policies, and those who believe that climate policies will create jobs and improve working conditions in the areas where they live (31% and 24%, respectively) are outnumbered by those who believe the opposite (35% and 34%, respectively). Fairness of climate policies The last section of the report looks at how the Nordic people perceive the fairness of climate policies in distributional terms. In the survey, the respondents were asked to judge to what extent they agree or disagree that everyone in their country or territory is equally affected by initiatives to fight climate change regardless of personal earnings, gender, age, country of origin and where they live – cities or rural areas. The results show that the Nordic people believe climate change initiatives affect citizens in different ways depending on their demographic, socioeconomic and territorial backgrounds. More than half of the respondents (56%) disagree that everyone is equally affected by initiatives to fight climate change regardless of earnings. Only 22% agree with this statement. Younger age groups are more pessimistic than older age groups on this point (66% in the 18-29 age group compared to 41% in the 65+ group). Almost half of respondents (48%) agree that climate policies are fair from a gender perspective, while 25% disagree with this statement and 23% are neutral. Roughly one in three (30%) respondents in the Nordic Region agree that people are equally affected by climate change initiatives regardless of age, 41% disagree with this statement and 25% are neutral. More than one third (35%) of the Nordic population agree that everyone is equally affected by initiatives to fight climate change regardless of the country of origin, while 34% of them disagree. More than half of respondents (56%) think that the impact of climate initiatives differs between rural and urban areas, while only 22% think that all areas are equally affected. Respondents who live in cities are more likely to respond that climate policy impacts differ between rural and urban areas (60%) than respondents who live in rural areas (55%) and towns and suburbs (53%). One third (33%) of respondents in the survey think that the Sámi population is affected by climate change initiatives to the same extent as the rest of the population. In Greenland, a majority of the population (62%) agrees that the indigenous population in Greenland is equally affected by measures to combat climate change. The results from this survey conducted in the autumn of 2022, show that the population in the Nordic Region perceive the impacts of climate mitigation policies in different ways. These results can raise awareness and stimulate debate about the implementation of climate mitigation policies for a just green transition.
