Resumen

Abstract. Pollution aerosols strongly influence the composition of the Western Mediterranean basin, but at present little is known on their optical properties. We report in this study in situ observations of the single scattering albedo (ω) of pollution aerosol plumes measured over the Western Mediterranean basin during the TRAQA (TRansport and Air QuAlity) airborne campaign in summer 2012. Cases of pollution export from different source regions around the basin and at different altitudes between ∼ 160 and 3500 m above sea level were sampled during the flights. Data from this study show a large variability of ω, with values between 0.84–0.98 at 370 nm and 0.70–0.99 at 950 nm. The single scattering albedo generally decreases with the wavelength, with some exception associated to the mixing of pollution with sea spray or dust particles over the sea surface. The lowest values of ω (0.84–0.70 between 370 and 950 nm) are measured in correspondence of a fresh plume possibly linked to ship emissions over the basin. The range of variability of ω observed in this study seems to be independent of the source region around the basin, as well as of the altitude and aging time of the plumes. The observed variability of ω reflects in a large variability for the complex refractive index of pollution aerosols, which is estimated to span in the large range 1.41–1.77 and 0.002–0.097 for the real and the imaginary parts, respectively, between 370 and 950 nm. Radiative calculations in clear-sky conditions were performed with the GAME radiative transfer model to test the sensitivity of the aerosol shortwave Direct Radiative Effect (DRE) to the variability of ω as observed in this study. Results from the calculations suggest up to a 50 and 30 % change of the forcing efficiency (FE), i.e. the DRE per unit of optical depth, at the surface (−160/−235 W m−2 τ−1 at 60° solar zenith angle) and at the Top-Of-Atmosphere (−137/−92 W m−2 τ−1) for ω varying between its maximum and minimum value. This induces a change of up to an order of magnitude (+23/+143 W m−2 τ−1) for the radiative effect within the atmosphere.

Resumen

This study describes the reproductive biology of the Japanese threadfin bream, Nemipterus japonicus (Bloch, 1791) captured from the Southern Java Waters (FMA-RI 573). Fish monthly sampling collection was conducted from July to December 2022 at three fish landing ports: PPI Ciwaru, PPN Palabuhanratu, and PPI Binuangeun. Overall, 951 individuals consisting of 469 males (49.32%) and 482 females (50.68%), with a size range of 92-300 mm and a weight range of 10–344 g were collected. The sex ratio is balanced (1:1.10), with fecundity ranging from 10,079 to 82,650 eggs. The length at first maturity is 146 mm for males and 141 mm for females. The Japanese threadfin bream is a total spawner. Spawning occurs throughout the sampling period, with a peak in October-November. The length-based spawning potential ratio (LBSPR) measures the sustainability of fish stocks, indicating that Japanese threadfin bream in southern Java is in an overexploited condition.

Resumen

Objectives: To determine symptomatology, clinical class, and topographic patterns of varicose veins in a consecutive series of patients with venous complaints. Methods: We performed clinical examination and duplex scanning of 498 lower limbs in 317 patients with obvious varicose veins for whom no previous treatment had been undertaken. Results: Classes of chronic venous insufficiency (CVI) in 498 legs: grade 0: 117 (23.5%); gr 1: 310 (62.2%); gr 2: 47 (9.4%); gr 3: 24 (4.8%). Duplex-detected venous reflux was found in the greater saphenous vein territory (junction or trunk or related perforator or main tributary) in 423 limbs (85.3%) the sapheno-femoral junction was incompetent in only 342 legs (68.7%). Reflux was found in the lesser saphenous vein territory in 100 limbs (20.1%) and in sapheno-popliteal junction in 92 (18.5%). Strictly non saphenous origin of varicosities was found in 31 limbs (6.2%). Deep venous incompetence was found in 48 legs (9.6%). Conclusions: These findings yield data on the distribution and occurence of lower limbs venous lesions in patients with varicose disease.

Resumen

The influence of prior pack boriding on the microstructure and properties of nanobainitised X37CrMoV5-1 hot-work tool steel was investigated in the present work. Pack boriding was conducted at 950 °C for 4 h. Nanobainitising consisted of two-step isothermal quenching at 320 °C for 1 h, followed by annealing at 260 °C for 18 h. A combination of boriding with nanobainitising constituted a new hybrid treatment. The obtained material exhibited a hard borided layer (up to 1822 ± 226 HV0.05) and a strong (rupture strength 1233 ± 41 MPa) nanobainitic core. However, the presence of a borided layer decreased mechanical properties under tensile and impact load conditions (total elongation decreased by 95% and impact toughness by 92%). Compared with borided and conventionally quenched and tempered steel, the hybrid–treated material retained higher plasticity (total elongation higher by 80%) and higher impact toughness (higher by 21%). It was found that the boriding led to the redistribution of carbon and silicon atoms between the borided layer and substrate, which could influence bainitic transformation in the transition zone. Furthermore, the thermal cycle in the boriding process also influenced the phase transformations during subsequent nanobainitising.

Resumen

Background: Primary hypertension is the most common (almost 95%) and it can easily be controlled through lifestyle modification by regular exercise and controlled diet plan. Magnesium and zinc supplementation can alleviate essential hypertension. Methods: 73 hypertensive patients were recruited. Thrice in a row with interval of 5 minutes, twice a day for 7 days high BP monitoring was done and ensured daily intake of Mg (300 mg) and Zn (10 mg) for 4 weeks. Thereafter again 4th week home Blood pressure monitoring was done. Study was done from 25 April 2023 to 24 April 2024. Secondary hypertension was excluded after proper radiological and pathological investigations. Results: Decrease in SBP by 6.9 mmHg, pre SBP 141±11.3 SD and post SBP 134±9.6 SD and DBP by 4.8 mmHg, pre DBP 91±7.8SD and Post DBP 86±73, observed after 4 weeks supplementation. In 30 medicated patients, antihypertensive showed decrease in SBP by 4.6 mmHg, pre SBP 137±11.5 SD and post SBP 132±9.6 SD with and DBP by 4.7 mmHg, Pre DBP 89.6±9.2SD and post DBP 84.9±8.7. Whereas, in a group of 43, without any medicine exhibited decline in SBP by 8 mmHg (Pre SBP 144±10 SD and Post SBP 136±9.5 and DBP by 5 mmHg, pre DBP 92±6.8 SD and post DBP 87±0.6.3 SD.

Resumen

In conditions of vegetative trial carried out against selective backgrounds in 2017-2019 the response of 27 flax samples to a decrease in soil acidity to neutral pHKCl was studied. The scheme of the experiment was as follows: variant I (control) − pHKCl 5.3-5.5, P2O5 − 320-340 mg/kg, K2O − 81-92 mg/kg; variant II − pHKCl 6.2, P2O5 − 312-345 mg/kg, K2O − 84-98 mg/kg. It has been shown that during the «herringbone» phase in the majority of studied flax genotypes against the background of pH 6.2, the symptoms of “physiological oppression” of flax were observed: small spots developed on the upper leaves, the plants stopped growing, the stems thickened, and the tops of severely affected plants died off. As a result, at the beginning of the growing season at plant height of 7-10 cm, most of the samples were severely affected (from 69 to 100 %). The exceptions were varieties of fibre-flax Hermes (France), Vega 2 (Lithuania), Atlant (Russia) and linseed genotypes No. 3896 (Russia) and Norlin (Canada), which had a weak and medium degree of affection (8.3-45.5 %). Moreover, these genotypes showed a high level of both biological (75-90 %) and agronomic (77.3-85.6 %) resistance in the phase of "early yellow ripeness". The identified flax collection samples can be used as sources of resistance to flax «physiological oppression» caused by stressful edaphic factors in a neutral environment. On the basis of the analysis of the main elements of fiber productivity in studied flax genotypes, it has been established that against the background of pH 6.2 the reduce in plant height was from 11.4 to 52.1 % relative to the control, weight of the technical part of the stem − from 7.2 to 83.4 % , fiber mass − from 9.6 to 85.1 %. For the first time, on the basis of hybridological analysis, an assumption was done as to the pres-ence of a strong dominant gene, controlling the resistance to high soil pH values in the Hermes (France) flax variety and the linseed line No. 3896 (Russia).

Resumen

Abstract In the late summer or autumn of the year 384, the Urban Prefect Q. Aurelius Symmachus forwarded from Rome to Milan a relatio requesting the restoration of the Altar of Victory to the senate-house and the renewal of imperial subsidies for Rome’s priestly colleges. Although the position of the emperor Valentinian II (375-92) was insecure-his elder brother, Gratian (367-83), had been killed at Lyon the year before and the usurper Magnus Maximus (383-8) now controlled Gaul and Spain-Milan’s forceful bishop, Ambrose, persuaded Valentinian to deny the prefect’s request.1 Three years later, in the summer of 387, Maximus led his army from Gaul into northern Italy and Valentinian’s court took refuge with the emperor Theodosius I (379-95) in the east. The following summer, Theodosius himself marched west, defeated Maximus, and reinstated Valentinian. Theodosius then stayed on in Italy for three years, not returning east until mid-391.

Resumen

ЦЕЛЬ: оценить структуру и распространенность сердечно-сосудистых и метаболических заболеваний среди пациентов с первичным гиперпаратиреозом. МАТЕРИАЛЫ И МЕТОДЫ: двухэтапное исследование включало изучение данных Всероссийского регистра пациентов с ПГПТ, внесенных в онлайн базу на 01.12.2022, а также одноцентровое одномоментное сравнительное исследование больных, пролеченных в ФГБУ «НМИЦ эндокринологии» Минздрава России с января 2017 г. по декабрь 2021 г. РЕЗУЛЬТАТЫ: в первую часть исследования вошли 4892 пациента с ПГПТ, среди них 4318 (92,3%) женщин и 374 (7,6%) мужчины в возрасте 66 [58; 73] лет. Медиана длительности заболевания составила 5 лет. Медиана кальциемии составила 2,74 [2,62; 2,90] ммоль/л, ПТГ - 143,9 [97,8; 231,6] пг/мл. 2308 (47,2%) пациентов имели различные сердечно-сосудистые заболевания. В общей выборке частота АГ составила 96,1%, при этом гипертрофия левого желудочка выявлена у 5,8% пациентов. ИБС в анамнезе диагностирована у 20,1%, кальцификация структур сердца и/или сосудов - у 2,7%. Пациенты с бессимптомным ПГПТ были значимо моложе и отличались от лиц с манифестной формой более низкими концентрациями ПТГ, общего и ионизированного кальция, фосфора, более высокой СКФ. При мягком течении заболевания частота ССЗ в целом, и АГ и ИБС в частности была статистически значимо ниже, чем в группе с манифестным ПГПТ. Во второй части исследования участвовали 842 пациента с ПГПТ, среди них 779 женщин (92,5%) и 63 мужчины (7,5%). Частота АГ, ИБС, ХСН и атеросклероза БЦА была выше среди пациентов старшей возрастной группы (66 лет и старше), достигая 79%, 11%, 8% и 84%, соответственно. Факторами повышенного риска ССЗ у лиц с ПГПТ являются возраст >56 лет (AUC=0,782), СКФ <92 мл/мин/1,73 м2 (AUC=0,714) и ИМТ >28,3 кг/м2 (AUC=0,682). ОШ присочетании всех трех факторов составило 4,11 (95% ДИ: 2,99-5,79). ВЫВОДЫ: по данным всероссийского регистра, среди пациентов с ПГПТ различных возрастных групп частота АГ варьирует в пределах14,5-52,5%, ИБС – 0,5-14% случаев. CCЗ у пациентов с ПГПТ ассоциированы с такими “классическими” ФР, как возраст, снижение СКФ и избыточная масса тела. Однако, у пациентов с ПГПТ значимое повышение риска ССЗ (более чем в 4 раза) возникает уже при начальных изменениях указанных параметров (СКФ < 92 мл/мин/1,73м2, ИМТ >28,3 кг/м2) и в относительно молодом возрасте (старше 53 лет).

Resumen

Abstract To develop a low formation damage clay stabilizer, a kind of organic polyether amine clay stabilizer (OPACS) was synthesized. Compared with the commercial clay stabilizers, the application performance of the OPACS was investigated. OPACS was synthesized with 1, 2-propanediol, 2-(chloromethyl)oxirane and ammonia as main raw materials. The molecular structure of OPACS were characterized by FTIR and NMR, and its anti-swelling performance was tested by centrifugation. Other performance, including its temperature resistance, acid and alkali resistance, elution resistance and etc., were also researched. Different permeability cores were used to test the formation damage of OPACS, and its anti-swelling mechanism was studied by SEM. The FTIR and NMR spectra showed that the expected product structure was synthesized. When the clay stabilizer was adding with 2.0 wt.%, the anti-swelling rate of OPACS was over 90% which was better than the commercial clay stabilizers (about 80%) we bought. At the temperature range of 20 °C-120 °C and the pH range of 2-12, the anti-swelling rate of OPACS changed less than 2.5%. In the long-term efficacy test, the elution recovery rate of OPACS was higher than 92% within the concentration between 0.5 wt.%-3.0 wt.%. Natural cores with different permeability were selected for core flow experiments. The test results showed that the permeability recovery rate of cores were more than 95% treated with OPACS, which meant the formation damage value was less than 5%. From the SEM of clay treated with different clay stabilizers, we could find out the structure of clay treated with OPACS was more compact than those treated with other stabilizers we bought. These results have shown that OPACS can effectively inhibit the water absorption swelling of clay and recovery formation damage, which are helpful to the EOR and friendly to the environment.

Resumen

ЦЕЛЬ: оценить различия в мочевой экскреции коллагена I и IV типа у больных сахарным диабетом 2 типа (СД2) и различными вариантами хронической болезни почек (ХБП). МАТЕРИАЛЫ МЕТОДЫ: обследовано 140 больных СД2 длительностью ≥10 лет, 48 мужчин и 92 жен- щины. Пациенты c длительностью СД более 10 лет были разделены на подгруппы: 1) больные СД без ХБП (ХБП–, N=35); 2) нормоальбуминурическая ХБП (НА-ХБП): скорость клубочковой фильтрации (СКФ) по CKDEPI <60 мл/мин, отношение альбумин/креатинин мочи (АКМ) <3,0 мг/ммоль (N=35); 3) альбуминурия без снижения СКФ (А-ХБП–): рСКФ ≥60 мл/мин, АКМ ≥3,0 мг/ммоль (N=35); 4) альбуминурическая ХБП (А-ХБП+): рСКФ <60 мл/мин, АКМ ≥3,0 мг/ммоль (N=35). Контроль составили 20 человек без нарушений углеводного обмена. Мочевая экскреция коллагена I и IV типов исследована методом ИФА и нормирована на концен- трацию креатинина мочи. РЕЗУЛЬТАТЫ: больные СД2 характеризовались достоверным увеличением мочевой экскреции кол- лагена IV типа (в 1,7 раза, p=0,002) и тенденцией к увеличению экскреции коллагена I типа (в 1,3 раза, p=0,11). Увеличение экскреции коллагена I и IV типа было достоверным в группах больных с альбумину- рией (А-ХБП− и А-ХБП+). В группе А-ХБП− наблюдалось увеличение экскреции коллагена I типа в 2,3 раза в сравнении с группой НА-ХБП (p=0,006) и увеличение экскреции коллагена IV типа в 1,8 раза в сравнении с контролем (p=0,03). В группе А-ХБП+ было выявлено увеличение экскреции коллагена I типа в 2,5 раза в сравнении с контролем и группой ХБП− (p=0,02 и p=0,008, соответственно) и в 3,1 раза в сравнении с группой НА-ХБП (p<0,001). В группе А-ХБП+ отмечалось увеличение экскреции коллагена IV типа в 2,1 раза в сравнении с контролем (p=0,002). В группах ХБП− и НА-ХБП изменения экскреции коллагена I и IV типа в сравнении с контролем были недостоверными (все p>0,05). Коллаген I и IV типа показали положительные корреляционные связи с АКМ (r=0,49, p<0,001 и r=0,34, p<0,001, соответственно). Экскреция коллагена I типа, в отличие от коллагена IV типа, положительно коррелировала с суточной протеинурией (r=0,36, p<0,001 и r=0,19, p=0,03, соответственно). Данные маркеры не были ассоциированы с величиной СКФ (r=−0,05, p=0,50 для коллагена I типа и r=−0,09, p=0,28 для коллагена IV типа). Экскреция коллагена I типа, в отличие от коллагена IV типа, была достоверным фактором, ассоциированным с альбуминурией у боль- ных СД2, в многофакторной модели, учитывающей пол, возраст, ИМТ, длительность СД и HbA1c (ОШ=1,16, 95% ДИ 1,01–1,32 пг/ммоль, p=0,03 для альбуминурии, ОШ=1,43, 95% ДИ 1,03–2,00 пг/ммоль, p=0,03 для группы А-ХБП+). Оба исследованных маркера не были ассоциированы со снижением СКФ<60 мл/мин в многофакторных моделях. ВЫВОДЫ: полученные данные свидетельствуют об ассоциации экскреции коллагена I и IV типа с аль- буминурическими вариантами ХБП у больных СД2. При этом экскреция коллагена I типа в сравнении с экс- крецией коллагена IV типа демонстрирует более значимые связи с альбуминурическими вариантами ХБП.

Resumen

In platelets exposed to chelating agents at 37°C and recalcified, aggregation to ADP, adrenaline, collagen and thrombin were either abolished or markedly reduced (1). This phenomenon has been suggested to be caused by disruption, by Ca2+ deprivation, of the fibrinogen receptor (glycoprotein lib Ilia complex) on the surface of the platelet (2). This effect was dependent on the exposure time of Ca2+ chelators and was reduced at lower temperatures. We have investigated the effect of exposure of human platelets to EGTA upon aggregation to a range of agonists at both 37 and 25°C. EGTA (5 mM) was incubated with citrated (12.9 mM) whole blood for either 0, 1, 5, 15 or 30 min. One minute following recalcification (5 mM CaCl2), full aggregation concentration-response curves were constructed to ADP and adrenaline (0.1 to 3 μM), PAF (3 to 100 nM), collagen (0.1 to 4 μg/ml) and U46619 (0.03 to 1 μM), using a platelet counting technique (3). At 25°C, EGTA produced little or no significant loss of sensitivity to any agonist. At 37°C marked rightward shifts of the ADP, adrenaline and PAF aggregation curves occurred which were related to the time of incubation with EGTA (e.g. ADP concentration ratios (CR) of 2.0 (0.8-4.8), 4.7 (2.1-10.7), › 186.6 (135.2-257.6) (95% confidence intervals n=4) obtained at 1, 5 and 15 min respectively). Following 30 min incubation aggregation to all three agonists was abolished (up to ADP 300 pM; adrenaline 100 μM; PAF 10 μM). In contrast, whilst collagen and U46619 concentration-effect curves were displaced to the right following 30 minutes exposure to EGTA (CR =13.6 (6.1-30.4) and 9.0 (4.3-18.7) respectively, n=4) full aggregation curves could still be established. Furthermore, a 60 min incubation with EGTA caused little further effect. Our findings suggest platelet agonists such as collagen and U46619, but not ADP, adrenaline and PAF, can evoke expression of a population of fibrinogen receptor sites involved in platelet aggregation that are inaccessible to EGTA.(1) Zucker, MB & Grant, RA (1978).

Resumen

ЦЕЛЬ: изучить диагностические возможности разработанного мобильного приложения с точки зрения оценки вариабельности гликемии и времени в целевом диапазоне глюкозы крови. МАТЕРИАЛЫ И МЕТОДЫ: с целью оптимизации самоконтроля пациентов с сахарным диабетом (СД) разработано мобильное приложение для мониторинга глюкозы крови «Dialog GM» (Русанов А.Н., Родионова Т.И.; свидетельство о регистрации ПрЭВМ №2022665169, 11.08.2022). Мобильное приложение используется совместно с глюкометром и рассчитывает следующие параметры гликемического контроля: средние значения гликемии, параметры вариабельности гликемии (SD, CV, MAGE), показатели нахождения в различных диапазонах глюкозы крови (TIR, TAR, TBR). В рамках пилотного исследования проведен анализ историй болезни пациентов, проходивших непрерывный мониторинг глюкозы (НМГ) крови с помощью системы Medtronic iPro2 в ГУЗ Саратовская ГКБ №9. Критерии включения: СД 1 типа, продолжительность НМГ – 6-7 дней, ежедневный контроль гликемии глюкометром 7 и более раз в день на фоне НМГ. Данные дневников самоконтроля пациентов были оцифрованы и загружены в программное обеспечение (ПО) Dialog GM для дальнейшего анализа данных. Полученные результаты сравнивались с аналогичными па- раметрами, рассчитанными на основании НМГ с помощью ПО Medtronic CareLink iPro (эталонный метод). Статистический анализ данных проведен с помощью программы IBM SPSS Statistics, v.26. Чувствительность и специфичность выявления дисгликемии оценивались с учетом критериев Международного консенсуса по НМГ. РЕЗУЛЬТАТЫ: в исследование включено 30 пациентов со следующими характеристиками: возраст – 34,3±9,1 лет; длительность СД – 9,7±7,7 лет; уровень гликированного гемоглобина – 8,5±2,1%; женщины – 70%, мужчины – 30%. Проведен анализ 1653 измерений с помощью глюкометра (7,6±1,0 измерений/ сутки) и 53266 измерений с помощью НМГ. Результаты анализа с применением ПО Dialog GM: средняя глюкоза крови – 8,8±2,3 ммоль/л; SD – 3,3±1,0 ммоль/л; CV – 38,4±10,6%; MAGE – 6,1±2,1 ммоль/л; TIR – 57,0±20,8%; TAR – 35,1±23,4%; TBR – 7,9±7,6%. Результаты анализа на основании данных НМГ: средняя глюкоза – 8,8±2,1 ммоль/л; SD – 3,0±0,9 ммоль/л; CV – 34,1±9,9%; MAGE – 5,8±1,7 ммоль/л; TIR – 60,2±21,6%; TAR – 33,8±23,9%; TBR – 6,1±5,9%. При сопоставлении измерений с помощью двух методов были выявлены статистически значимые различия по уровню SD (p<0,05) и CV (p<0,05), при оценке остальных параме- тров значимых различий не выявлено (p>0,05). Коэффициент корреляции Пирсона (r) для показателей, рассчитанных исследуемым и эталонным методами: средняя глюкоза крови – 0,97; SD – 0,87; CV – 0,92; MAGE – 0,77; TIR – 0,89; TAR – 0,95; TBR – 0,79 с уровнем p<0,05 для всех параметров. ПО Dialog GM позво- лило диагностировать нарушенные показатели гликемического контроля с соответствующими уровнями чувствительности и специфичности: SD – 94% и 77%; CV – 93% и 80%, MAGE – 95% и 71%, TIR – 94% и 70%, TAR – 92% и 75%, TBR – 76% и 86%. ВЫВОДЫ: разработанное мобильное приложение Dialog GM, примененное совместно с глюкометром, может оказаться доступным, высокочувствительным методом исследования вариабельности гликемии и времени в целевом диапазоне глюкозы крови. Планируется дальнейшее исследование и совершенство- вание разработанных методик мониторинга гликемии.

Resumen

Engaging students in research is a high impact practice known to increase underrepresented students’ persistence in Science, Technology, Engineering, and Mathematics (STEM) fields and improve their graduation rates. For broad impact, research infusion can be implemented through careful redesign of courses or through the adoption of research modules to supplement class instruction and existing student training programs. In this paper, we present data on a program for the integration of research-infused curriculum in major courses across a variety of disciplines in STEM. Specifically, the program's goal is to have faculty engage in a redesign of the class to exemplify how specific disciplines engage in research. The course redesign can be in the form of activities for in-person education or as interactive activities for online learning. Fourteen courses were included in this analysis. Anonymous surveys were administered at the end of the fall or spring semester to 864 students in the 14 courses from Fall 2020 to Spring 2023. A total of 643 students (74% response rate) participated in the evaluation.Gains in research skills: Students indicated how much they gained in various skills (on a scale of 1: no Gain to 5: Great Gain) as a result of the course. Overall, a high percentage of students (92-96%) reported gains of some kind, while only about 4% of students reported no gains, though a slightly higher proportion reported no gains in understanding what everyday research work is like (8%). Results suggest that on average, students reported moderate to good gains (Ms ranged from 3.36 to 3.70) for all items. Most students felt they had good gains in problem-solving, understanding the relevance of research, understanding research reports, and interpreting results, and moderate gains in comfort discussing research concepts and confidence in ability to do well in research courses. Course Redesign Goals: Students also indicated high levels of agreement about three redesigned course goals: Understanding research-related ethical issues, effective communication of research, and stimulating research interest on a scale ranging from 1 (Strongly Disagree) to 4 (Strongly Agree). Most students agreed/strongly agreed that due to the course, they were able to effectively communicate research information to different audiences (80% Mode=3). Although most students agreed/strongly agreed that the course stimulated interest in research (71%, Mode=3) and helped them understand research ethics (73%; Mode=3), close to one-third of students disagreed (17-23%) or strongly disagreed (3-7%) with these statements.Intention to Pursue Research: More than half of students in the redesigned course indicated that they increased their likelihood of exploring research careers (62%), joining a research/lab training program (64%), and pursuing research-focused courses (62%).Effects of Course Modality: When examining differences by the modality of the course, there were no statistically significant differences between courses that were virtual and courses that were face-to-face for gains in research skills, (X2(1)=0.22, p=.641), research intentions X2(1)=1.30, p=.254, research career perceptions (X2(1)=2.05, p=.152), or course redesign goals, X2(1)=0.08, p=.778.Faculty who received the award found it helpful in redesigning courses to make them more interactive, problem- and research- focused. One awardee shared, “through this program, I can see more underrepresented students more interested in machine learning, data science and artificial intelligence.” Overall, the redesigned courses had a large impact on student’s research skill gains. Students reported moderate to good gains in understanding relevance of research in their discipline and skills important to research like problem solving, understanding research papers, and interpreting research results. The modality of the course (virtual vs. face-to-face) had little impact. Thus, research-focus activities intentionally embedded in courses strengthening the research foundation of students and should be encouraged as a high-impact practice.

Resumen

We investigate seismic attenuation characteristics of the Lower St. Lawrence seismic zone in southeastern Quebec. This zone is located ~400 km downstream from Quebec City and is between the Quebec North Shore and the Lower St. Lawrence. We used earthquake recordings from 5 broadband and 5 short period seismograph stations of the Canadian National Seismic Network (CNSN) across the region. Our dataset is comprised of 847 earthquakes recorded between 1985 and 2022 with magnitudes ranging from 2.0 to 5.1, depths from 0 to 30 km and epicentral distances of 5 to 100 km. This gives a total of 446 high signal-to-noise (S/N) traces (S/N?5.0) useful for QC calculation (with a maximum ellipse parameter, a2, of 100) across the region. Coda windows were selected to start at tc = 2tS (two times the travel time of the direct S wave), and were filtered at center frequencies of 2, 4, 8, 12 and 16 Hz. Our study reveals a consistent pattern. We find that the lowest overall average of Q0 (Q at 1 Hz) values are at the three stations (GSQ, ICQ and SMQ) within 100 km of a moderate earthquake of mN 5.1 in 1999 (e.g., Q0 of 81, 88 and 80, respectively). We determined temporal variations in attenuation following the 1999 earthquake. The overall average of Q0 decreased from 87 (before the mainshock) to 77 (GSQ, D=96 km), from 92 to 85 (ICQ, D=69 km) and from 88 to 82 (SMQ, D=73 km). These results are in agreement with global studies that show a decrease in Q0 following a significant earthquake, (e.g., M &gt; 5) likely the result of increased fracturing and fluids in the epicentral region. An average for all the data results in a Q relationship of QC = 86f1.07 for the frequency band of 2 to 16 Hz for the entire region.
