Abstract. Windstorms are natural disturbance agents in forests playing a role in natural forest regeneration. In Finland, the most severe individual windstorms have commonly damaged 2–4 million m3 of timber. In addition to financial losses caused to forest owners, windthrown trees have in many cases seriously disrupted the functionality of the national power grid. Communicating windstorm risks in duty forecasting is difficult. In this study, we aimed at developing windstorm impact estimates for forest damage in Finland to help the forecaster to improve communication of the risks of windstorms. We have compared the volume of forest damage caused by the most intense windstorms in Finland during the recent decade to the observed maximum inland wind gust speeds associated with the same windstorms. It was found out that the volume of forest damage follows approximately a power relation as a function of wind gust speed with a power of ∼10. This is a tentative estimate because of a short time series and small number of inspected windstorms. Moreover, also wind direction, location of the affected area and soil properties among other factors have an impact to the amount of damage as illustrated in our inspection. Despite the shortness of the time series, we believe that our results demonstrating the steep increase in the impacts of windstorms with an increasing windstorm intensity are valuable. However, more detailed investigations with longer time series are needed in order to more specifically communicate the windstorm risks and their impacts in boreal forests.

Information on the historical background of the present forest conditions is needed for proper decisions on forest management. Disturbances play a major role in the formation of forest structure and composition. This paper compares the present break-up of mountain spruce stands in the Bohemian Forest (in the Šumava Protected Landscape Area) with conditions during their initiation using dendrochronological techniques. On three selected localities we established two study plots within relatively old stands of unknown origin. Stands were recently broken up by a windstorm. The present situation was described by diameter and decay class distribution. To describe the situation at the stand initiation, we cored at least 40 stems on each plot to get the age structure and growth series of trees. Disturbances were marked by discovering synchronous releases on tree-ring series. Main population waves were initiated in association with severe disturbances during a relatively short period, leading to the establishment of relatively even-aged, homogeneously looking stands. The disturbances were synchronized between plots and accounted for by historically known windstorms or bark beetle outbreaks; notwithstanding, logging as a disturbance factor is also particularly possible.

"Return levels of extreme European windstorms, their dependency on the North Atlantic Oscillation, and potential future risks". Natural Hazards and Earth System Sciences 23, n.º 12 (18 de dezembro de 2023): 3845–61. http://dx.doi.org/10.5194/nhess-23-3845-2023.
Texto completo da fonteResumo:
Abstract. Windstorms are the most damaging natural hazard across western Europe. Risk modellers are limited by the observational data record to only ∼ 60 years of comprehensive reanalysis data that are dominated by considerable inter-annual variability. This makes estimating return periods of rare events difficult and sensitive to the choice of the historical period used. This study proposes a novel statistical method for estimating wind gusts across Europe based on observed windstorm footprints. A good description of extreme wind speeds is obtained by assuming that gust speed peaks over threshold are distributed exponentially, i.e. a generalised Pareto distribution having a zero shape parameter. The threshold and tail scale parameter are estimated at each location and used to calculate estimates of the 10- and 200-year return levels. The North Atlantic Oscillation (NAO) is particularly important for modulating lower return levels and modulating the threshold, with a less detectable influence on rarer extremes and the tail scale parameter. The length of historical data required to have the lowest error in estimating return levels is quantified using both observed and simulated time series of the historical NAO. For reducing errors in estimating 200-year return levels of an independent 10-year period, a data catalogue of at least 20 years is required. For lower return levels the NAO has a stronger influence on estimated return levels, and so there is more variability in estimates. Using theoretical estimates of future NAO states, return levels are largely outside the historical uncertainty, indicating significant increases in risk potential from windstorms in the next 100 years. Our method presents a framework for assessing high-return-period events across a range of hazards without the additional complexities of a full catastrophe model.

For almost six and a half centuries, the wardens (and later the Deans) of St George's Chapel have been lodged in the extreme north-east corner of the Lower Ward at Windsor Castle. From fairly modest beginnings, the house developed into a much grander building, after the construction of a huge new chapel in the late fifteenth century. After the Elizabethan settlement it developed further and was a childhood home of Sir Christopher Wren, before being vandalized in the Commonwealth period. Following the Reformation, it was reconstructed and then given a grand new front in 1710 for the first of a series of aristocratic Deans. The final major rebuilding was carried out in 1831 immediately after the demise of George IV, and the house was used by Queen Victoria as a sort of ‘confessional’ and very private access to the royal pew after her widowhood. Today it is still a fine house after being reduced in size for twentieth-century Deans who do not have large families and many servants. Its rendered south front can still be seen immediately behind the buttressed east end of the Albert Memorial Chapel (fig. 1).

Post-Brexit Northern Ireland occupies a unique position in the internal market of the United Kingdom due, primarily, to the Protocol on Ireland / Northern Ireland, or Windsor Framework. Agreed as part of the UK-EU Withdrawal Agreement, the Protocol/Windsor Framework provides that EU Single Market rules concerning the free movement of goods, customs, VAT, state aid and energy markets, continue to apply in Northern Ireland, despite it having formally left the EU along with the rest of the UK. To allow for the domestic implementation of the novel arrangements for post-Brexit Northern Ireland, set out in the Protocol/Windsor Framework, the UK Internal Market (UKIM) Act 2020 includes a series of specific provisions that except goods entering and leaving Northern Ireland from the ‘market access principles’ established by the UKIM Act 2020 in certain circumstances. This commentary introduces the UKIM Act 2020 then presents a review of its provisions that are specifically dedicated to post-Brexit Northern Ireland. Written in September 2023 the analysis then provides an assessment of the implications of measures agreed between the UK and EU laid down in the Windsor Framework texts which were published in February of this year. Based on the analysis of the UKIM Act 2020 set against the backdrop of the Protocol, then Windsor Framework, the commentary argues that the position of Northern Ireland post-Brexit is not only newly unique but also newly consequential for those both inside and outside its borders.

Abstract: This article reviews evaluation research on community policing (CP) in the City of Windsor, including the Windsor Police Service’s utilization of evaluation evidence. It examines five studies of the initial year of two CP patrol units, one beginning in 1990 and the other in 1992. The studies included surveys of the CP-related attitudes and experiences of constables, community residents, and managers of small business, as well as time series analyses of crime trends. The results provided favourable process and outcome evidence. By 1995, more than half the city population was serviced by CP units, and follow-up time series analyses reconfirmed the earlier encouraging crime trends findings. However, in contrast to the positive beginnings, a 1997 survey of the service’s membership revealed no strong support for CP, including an apparent division among management in attitudes about CP. Recent CP developments in the service are considered.

AbstractIntroduction:For patients who suffer out-of-hospital cardiac arrest, the time from collapse to initial defibrillation is the single most important factor that affects survival to hospital discharge. The purpose of this study was to compare the survival rates of cardiac arrest victims within an institution that has a rapid defibrillation program with those of its own urban community, tiered EMS system.Methods:A logistic regression analysis of a retrospective data series (n = 23) and comparative analysis to a second retrospective data series (n = 724) were gathered for the study period September 1994 to September 1999. The first data series included all persons at Casino Windsor who suffered a cardiac arrest. Data collected included: age, gender, death/survival (neurologically intact discharge), presenting rhythm (ventricular fibrillation (VF), ventricular tachycardia (VT), or other), time of collapse, time to arrival of security personnel, time to initiation of cardiopulmonary resuscitation (CPR) prior to defibrillation (when applicable), time to arrival of staff nurse, time to initial defibrillation, and time to return of spontaneous circulation (if any). Significantly, all arrests within this series were witnessed by the surveillance camera system, allowing time of collapse to be accurately determined rather than estimated. These data were compared to those of similar events, times, and intervals for all patients in the greater Windsor area who suffered cardiac arrest. This second series was based upon the Ontario Prehospital Advanced Life Support (OPALS) Study database, as coordinated by the Clinical Epidemiology Unit of the Ottawa Hospital, University of Ottawa.Results:The Casino Windsor had 23 cases of cardiac arrests. Of the cases, 13 (56.5%) were male and 10 (43.5%) were female. All cases (100%) were witnessed. The average of the ages was 61.1 years, of the time to initial defibrillation was 7.7 minutes, and of the time for EMS to reach the patient was 13.3 minutes. The presenting rhythm was VF/VT in 91% of the case. Fifteen patients were discharged alive from hospital for a 65% survival rate. The Greater Windsor Study area included 668 cases of out-of-hospital cardiac arrest: Of these, 410 (61.4%) were male and 258 (38.6%) were female, 365 (54.6%) were witnessed, and 303 (45.4%) were not witnessed. The initial rhythm was VF/VT was in 34.3%. Thirty-seven (5.5%) were discharged alive from the hospital.Conclusion:This study provides further evidence that PAD Programs may enhance cardiac arrest survival rates and should be considered for any venue with large numbers of adults as well as areas with difficult medical access.

In this paper the concept of a fractal and its dimension is presented. The fractal dimension of the horizontal component of several wind speed time series is determined by the variation method. It is concluded that the fractal dimension D=1.60 can be used to describe the wind both at Windsor, MA, and Altamont, CA. The fractal dimension is related to the universal estimate of the decay rate of turbulent kinetic energy in the wind.

Texto completo da fonteResumo:
Abstract Carboniferous sedimentation in the southern Gaspé Peninsula has fossilized a paleosurface which is now gradually being exhumed by erosion. Part of the surface was horizontally cut by a major peneplanation event that took place between 290 Ma (Permian) and 200 Ma (Jurassic). Exhumation of the surface below the peneplanation line must also have started by Jurassic time in response to the en bloc uplift of the evolving Atlantic Ocean's passive margins. Some geomorphic features of the exhumed paleosurface bring clues regarding Carboniferous paleoenvironments and tectonics. A planation surface limited by a scarp, which is leading to a higher planation surface occupied by the same rock formations, is here interpreted as a paleo- wave-cut platform (associated to the Windsor transgression) for it cannot be explained by differential erosion, fault movement or "etchplanation". A series of fault scarps cutting through planation surfaces are interpreted as being the result of post-Acadian fault activity. The preservation of limestone hogbacks on the exhumed paleosurface, which are interpreted as having evolved under an arid climate, is believed to be either related to a pre-Windsor clastic fossilization or to post-Windsor lateral displacement. The tightly embanked river system, which is still currently dissecting the Peninsula's main planation surface, and the karstic systems of both that surface and the exhumed paleosurface, are interpreted as having evolved since Jurassic Time, except for a few cases of river antecedence in the north-central highlands which are interpreted as representing even older river routes.

In 1946, W.H. Auden began a series of weekly lectures on Shakespeare's plays at New York's New School for Social Research. Arriving at The Merry Wives of Windsor, he pronounced it ‘a very dull play indeed’. Nevertheless, he allowed, ‘We can be grateful for its having been written, because it provided the occasion of Verdi's Falstaff, a very great operatic masterpiece’. Having nothing to say about The Merry Wives, he played a recording of the opera for the duration of the class.

Texto completo da fonteResumo:
The Supreme Court's 1997 decision in Amchem Products, Inc. v. Windsor struck down the most ambitious settlement class action ever attempted. The settlement was, however, the logical outgrowth of the federal judiciary's efforts in the early 1990s to resolve a "disaster" of "critical proportions." Many factors, not least the Supreme Court's decision in Amchem, turned the tide against this trend. Ironically, however, the post-Amchem world has come to look a lot like Amchem. The settlement's central feature-deferral of unimpaired claims to assure the availability of resources to compensate the sick-was subsequently incorporated (either by statute or through judicial decision) into the law of most states with heavy asbestos caseloads. Similarly, the bankruptcy of nearly all of the defendants whose cases would have been settled created a series of administrative claims-processing regimes similar to the Amchem settlement. This Article suggests that the Amchem settlement should be understood as a triumph of judicial statesmanship, and the reaction that took place in the late 1990s had tragic consequences. It also surveys what lessons we might learn from the Amchem experiment as we think about facilitating resolution of other mass torts in the future.

In the 1880s, the southwestern region of Ontario, including Essex County and Pelee Island, became home to a series of pioneering winemakers. While the story of the winemakers of Pelee Island has been told, far less has been written about the vineyards of the Windsor border region. Jules Robinet, emerged as a successful winemaker at the turn of the 20th century after a series of hardships wiped out most of his competition. In time, Robinet`s business flourished with the enactment of Prohibition laws in Canada and the United States. An immigrant from Rougemont, France, Robinet served as a key link in the migration chain of French labourers and grape growers who settled in and around the Town of Sandwich. For French immigrants, he emerged as an employer, business associate, and advocate for the community that found its roots in the very same region of France.

Texto completo da fonteResumo:
Four granitoid suites are recognized in the region of the Cape Ray Fault Zone of southwestern Newfoundland. The two oldest (Ordovician–Silurian (?)) suites represent partial melts of their enclosing host rocks. The Port aux Basques granite is modelled as a partial melt of the gneissic component of its host, Port aux Basques Complex. The Cape Ray granite forms a dominantly tonalitic terrane derived by partial melting of ophiolitic material. The Red Rocks granite and a megacrystic phase of the Cape Ray granite form coherent lines of geochemical descent from the parental tonalite but show evidence of some continental crust contamination.The Late Devonian Windowglass Hill granite is a subvolcanic equivalent of felsic volcanic rocks in the Windsor Point Group. Both units were derived as partial melts of continental crust.The post-tectonic, Late Devonian to Early Carboniferous Strawberry and Isle aux Morts Brook granites constitute the youngest granitoid suite in the region. These A-type granitoids were derived as partial melts of an underlying depleted granulitic (felsic) crust. The depleted nature of the source may have resulted from previous generation of the Windowglass Hill granite and Windsor Point Group. The only possible protolith for the granulitic source is Precambrian Grenvillian gneiss. The presence of this gneiss beneath the Cape Ray Fault Zone of southwestern Newfoundland implies that the complete series of lithologies is allochthonous.

Abstract. During the last decades, several windstorm series hit Europe leading to large aggregated losses. Such storm series are examples of serial clustering of extreme cyclones, presenting a considerable risk for the insurance industry. Clustering of events and return periods of storm series for Germany are quantified based on potential losses using empirical models. Two reanalysis data sets and observations from German weather stations are considered for 30 winters. Histograms of events exceeding selected return levels (1-, 2- and 5-year) are derived. Return periods of historical storm series are estimated based on the Poisson and the negative binomial distributions. Over 4000 years of general circulation model (GCM) simulations forced with current climate conditions are analysed to provide a better assessment of historical return periods. Estimations differ between distributions, for example 40 to 65 years for the 1990 series. For such less frequent series, estimates obtained with the Poisson distribution clearly deviate from empirical data. The negative binomial distribution provides better estimates, even though a sensitivity to return level and data set is identified. The consideration of GCM data permits a strong reduction of uncertainties. The present results support the importance of considering explicitly clustering of losses for an adequate risk assessment for economical applications.

The paper aims to assess the impact of deforestation due to windstorms on runoff in small mountain river basins. In the Boca and Ipoltica River basins, changes in forested areas were assessed from available historical and current digital map data. Significant forest losses occurred between 2004 and 2012. During the whole period of 1990–2018, forested areas in the Boca river decreased from 83% to 47% and in the Ipoltica River basin from 80% to 70%. Changes in runoff conditions were assessed based on an assessment of changes in the measured time series of the hydrometeorological data for the years 1981–2016. An empirical hydrological model was used to determine the design peak discharges before and after significant windstorms were estimated for different rain intensities and return periods. The regional climate scenario for the period 2070–2100 was used to assess the current impact of climate change and river basin deforestation on predicted changes in design floods in the coming decades. The effect of deforestation became evident in the extreme discharges, especially in future decades. In the Boca River basin, the estimated design floods increased by 59%, and in the Ipoltica River basin by 172% in the case of the 100-year return period.

Abstract. Studying changes in storm-induced forest damage in Finland has not been possible previously due to the lack of continuous, long series of impact data. We overcome this by combining emergency rescue data from the Finnish rescue services "PRONTO" (2011-) with ERA-Interim reanalysis data of wind gusts and soil temperatures to define exceedance thresholds for potential forest damage days. These thresholds were applied as a proxy for the period 1979–2013 in order to study the spatial and decadal characteristics of forest damage in Finland due to windstorms. The results indicated that the area most impacted by potential forest damage was the south-western part of Finland along the coast, with 1–10 damaging storm cases per year. A decadal examination highlighted a lull period in the number of potential forest damage days during the 1990s compared to the 1980s and 2000s, albeit no trend was evident. The inclusion of emergency rescue data allowed us for the first time to estimate the spatial distribution and decadal variations of potential forest damage days due to windstorms in Finland. The results achieved will encourage further development of thresholds for potential forest damage by including additional data sources and applying them to future climate scenarios.

This article considers the political impact of a series of billboards that appeared at the Windsor–Detroit border and the Tijuana–San Ysidro border between 1991 and 2007. While there is a significant asymmetry between the political tensions on the northern and southern borders of the United States, there are remarkable parallels and relays between events that have taken place in major cities on these borders that indicate that generalized border anxiety has spread far beyond the localized territory of the southern borderlands. In this heightened climate of border insecurity, artists and community groups have seized on the geopolitical confusion that has emerged in mainstream American media where issues such as terrorism and illegal migration have often been folded into the same discourse. While border regions are tightly controlled spaces, these projects have served to highlight contradictory narratives of globalization and security, unmasking national insecurities that have been submerged through the bureaucratic discourses of the North American Free Trade Agreement and the more recent Smart Border agreements.

AbstractDamages by wind and by European spruce bark beetle (I. typographusL.) were compared on the basis of the reports about the occurrence of harmful forest agents for the period 1964−1991 across former regional state forest directorates. In the given period, the quantity of salvage logging (70 million m3) was more than five times that of sanitation felling (13 million m3). Damage intensity increased over the decades. Using a cross-correlation function between the time series, an increase in the abundance ofI. typographusdue to windfall was demonstrated with a delay of 1–3 years. Wind damage was also shown to arise as a result of disturbed stand stability after sanitation felling with a stochastic delay of 1−5 years. Thus, disturbance of static stability of forest stands may be considered as one of the main harmful consequences of bark beetle outbreaks for the near future. Consequences for forest management are discussed.

Mapping forest disturbances is an essential component of forest monitoring systems both to support local decisions and for international reporting. Between the 28 and 29 October 2018, the VAIA storm hit the Northeast regions of Italy with wind gusts exceeding 200 km h−1. The forests in these regions have been seriously damaged. Over 490 Municipalities in six administrative Regions in Northern Italy registered forest damages caused by VAIA, that destroyed or intensely damaged forest stands spread over an area of 67,000 km2. The present work tested the use of two continuous change detection algorithms, i.e., the Bayesian estimator of abrupt change, seasonal change, and trend (BEAST) and the continuous change detection and classification (CCDC) to map and estimate forest windstorm damage area using a normalized burned ration (NBR) time series calculated on three years Sentinel-2 (S2) images collection (i.e., January 2017–October 2019). We analyzed the accuracy of the maps and the damaged forest area using a probability-based stratified estimation within 12 months after the storm with an independent validation dataset. The results showed that close to the storm (i.e., 1 to 6 months November 2018–March 2019) it is not possible to obtain accurate results independently of the algorithm used, while accurate results were observed between 7 and 12 months from the storm (i.e., May 2019–October 2019) in terms of Standard Error (SE), percentage SE (SE%), overall accuracy (OA), producer accuracy (PA), user accuracy (UA), and gmean for both BEAST and CCDC (SE < 3725.3 ha, SE% < 9.69, OA > 89.7, PA and UA > 0.87, gmean > 0.83).

The paper investigates weather-related fatalities over the territory of the Czech Republic in the 100-year period from 1921 to 2020. The unique database, created from documentary evidence (particularly newspapers), includes, for each deadly event, information about the weather event, the fatality itself, and related circumstances. A total of 2729 fatalities were detected during the 100-year period and were associated with various weather categories including frost (38%), convective storms (19%), floods (17%), fog (11%), snow and glaze ice (8%), windstorms (5%), and other inclement weather (2%). A detailed analysis was performed for each individual category. Fatalities occurred throughout the country, with a main maximum in winter (January) and a secondary maximum in summer (July), corresponding to the occurrence of extreme weather. Deaths were mainly interpreted as direct, caused by freezing to death/hypothermia or drowning, and occurred in the afternoon and at night in open countryside or on rivers and water bodies. Males outnumbered females, and adults outnumbered children and the elderly. Hazardous behavior was more frequent than non-hazardous behavior among victims. The information on fatalities and the structure of their characteristics strongly reflects historical milestones of the country, political and socioeconomic changes, as well as changes in lifestyle. Although important weather effects were observed on the deadliest events, the character of the data did not allow for clear evidence of the effects of long-term climate variability.

Texto completo da fonteResumo:
On 10 August 2020, a series of intense and fast-moving windstorms known as a derecho caused widespread damage across Iowa’s (the top US corn-producing state) agricultural regions. This severe weather event bent and flattened crops over approximately one-third of the state. Immediate evaluation of the disaster’s impact on agricultural lands, including maps of crop damage, was critical to enabling a rapid response by government agencies, insurance companies, and the agricultural supply chain. Given the very large area impacted by the disaster, satellite imagery stands out as the most efficient means of estimating the disaster impact. In this study, we used time-series of Sentinel-1 data to detect the impacted fields. We developed an in-season crop type map using Harmonized Landsat and Sentinel-2 data to assess the impact on important commodity crops. We intersected a SAR-based damage map with an in-season crop type map to create damaged area maps for corn and soybean fields. In total, we identified 2.59 million acres as damaged by the derecho, consisting of 1.99 million acres of corn and 0.6 million acres of soybean fields. Also, we categorized the impacted fields to three classes of mild impacts, medium impacts and high impacts. In total, 1.087 million acres of corn and 0.206 million acres of soybean were categorized as high impacted fields.

Texto completo da fonteResumo:
Abstract Extreme wind event in November 2004 caused spacious destruction of slope forests in the Tatra National Park, Slovakia. Relevant changes of land cover motivated researchers to investigate damaged forest ecosystem and its response to different environmental conditions. Surface ozone (O3) is a minor but not negligible compound of the ambient air. Control strategies for the reduction of O3 precursor emissions have been applied in Europe during the last two decades. In spite of these reductions, air quality indices for O3 suggest that highland sites are more vulnerable to health and environmental risk than lowlands where mostly emissions from road transport and industry are produced. Both anthropogenic sources and biogenic precursors (BVOC) from forest vegetation play a relevant role in the tropospheric photochemistry, especially at mountainous and rural locations. The parameters of air quality are measured at background station Stará Lesná in the High Tatras region since 1992 in frame of an European project EMEP. Long-term data series (1992-2013) of O3 concentrations obtained for site Stará Lesná provide specific opportunity to investigate the response of BVOC reduction on O3 variability after windstorm 2004. Evaluation of these data indicates moderate increase of annual, monthly and hourly O3 means for the period from 2005 to 2013 in comparison with the previous period 1992-2004. Temporal interpolation shows evident changes of O3 concentrations, especially ~30% increase for night hours in spring season and on the contrary ~15% decrease for daylight afternoon hours in summer season. Statistically significant changes were identified for spring months (April and May, 0-6 hours) and summer months (July, 12-20 hours). Increasing O3 values in the night may be associated with the absence of BVOC for ozonolysis reaction that is one of the mechanism for O3 depletion. On the other hand, the decline of daylight O3 values in summer suggests lower O3 production via photochemical mechanism.

Abstract Introduction. Among many problems present in studies evaluating associations between health conditions and exposure to ambient air pollution, there is the correlation between environmental factors. These issues are usually resolved by providing a correlation matrix for the parameters of interest. Aim. To explore correlations between environmental factors. Material and methods. As sample data we use environmental factors presented in Milan mortality data (Italy, 1980-1989) and emergency department visits for asthma in Windsor (Canada, 2004-2010). Here, we propose to use a series of quantile regression evaluations to emphasize and identify dependency among environmental factors. Results. This presentation outlines an important role to investigate the potential correlations among ambient air pollutants, weather factors, and the values of the Canadian Air Quality Health Index (AQHI). In environmental epidemiology studies, these components are usually used in a common statistical model. Their correlations affect the values of the estimated relative risks, odds ratios or other estimated health effects. The presented approach examines associations among the factors as well as changes in correlations along quantiles. The examples used in this study explain various environmental phenomena; for example, the negative relationship between ambient ozone and nitrogen dioxide. Conclusions. By a consequence, this work can aid in further developing policies aimed at reducing the health impacts of air pollution as it allows to identify highly correlated factors in the constructed models.

Wind and gravity both impact trees in storms, but wind loads greatly exceed gravity loads in most situations. Complex behavior of trees in windstorms is gradually turning into a controversial concern among ecological engineers. To better understand the effects of nonlinear behavior of trees, the dynamic forces on tree structures during periods of high winds have been examined as a mass-spring system. In fact, the simulated dynamic forces created by strong winds are studied in order to determine the responses of the trees to such dynamic loads. Many of such nonlinear differential equations are complicated to solve. Therefore, this paper focuses on an accurate and simple solution, Differential Transformation Method (DTM), to solve the derived equation. In this regard, the concept of differential transformation is briefly introduced. The approximate solution to this equation is calculated in the form of a series with easily computable terms. Then, the method has been employed to achieve an acceptable solution to the presented nonlinear differential equation. To verify the accuracy of the proposed method, the obtained results from DTM are compared with those from the numerical solution. The results reveal that this method gives successive approximations of high accuracy solution.

Extreme weather events can arrive unannounced and cause immense harm for communities. Especially in cities where many people live in close proximity, events like flash flooding, windstorms or even heat waves can cause property damage, overworking of the emergency infrastructure and death. Unfortunately, because climate change continues to alter weather patterns, from subtle local variations to changes in global factors like ocean currents, these events are occurring with increased frequency. There is a great need for accurate monitoring and prediction systems that can help forecast these catastrophes. Monitoring overall changes in the patterns of these events will also help governments and citizens better adapt and plan measures to protect themselves from climate change's inevitable impact. Professor Tomoko Matsui is an expert in the field of statistical spatial-temporal modelling. Matsui is heading up an international team of researchers at the Institute of Statistical Mathematics in Tokyo, Heriot-Watt University in UK and the National Institute for Environmental Studies in Tsukuba to find ways for using a variety of data including low-resolution surface meteorological observation, time-series measurements of ground surface temperature by high-resolution satellite and social media.

Texto completo da fonteResumo:
Viséan clastic units and structures at the northwest margin of the upper Paleozoic Maritimes Basin provide information on tectonic events that are only poorly recorded in more central parts of the basin. These continental units are time equivalent to marine sediments of the Windsor Group of Nova Scotia. They are herein assigned to the new Percé Group, which includes the La Coulée and Bonaventure formations, as well as a new unit, the Cap d'Espoir Formation. The latter unit unconformably underlies the Bonaventure Formation in a small but thick sub-basin of the Ristigouche Basin in eastern Quebec. It is characterized by a succession of sandstone and mudstone rhythmites that contrast with the coarse alluvial fan deposits of the overlying Bonaventure Formation. The Cap d'Espoir Formation was sourced from a broad area of subdued topography occupied by the Viséan La Coulée Formation and underlying units. Erosional remnants of the La Coulée Formation are unconformably overlain by the Bonaventure Formation in marginal parts of the Ristigouche Basin, whereas these units are separated by the Cap d'Espoir Formation in more central areas of the basin. The La Coulée and Cap d'Espoir formations underwent tilting and erosion during a normal faulting event that preceded deposition of the fault-controlled Bonaventure Formation. This series of events is interpreted to represent different steps in the reactivation of a pre-Carboniferous dextral strike-slip system in response to northwestsoutheast compression during the Viséan in Gaspésie.

Texto completo da fonteResumo:
Suspended Particulate Matter (SPM) plays an important role in controlling water quality, particularly in turbid estuaries. SPM may be impacted by changes in weather and climate, including potential changes in the frequency or intensity of extremes. Yet, the linkages between extreme events in wind and river discharge, and particularly the role these have on local dynamics and spatial patterns of estuarine SPM are, to date, largely unknown. This study investigates the effects that wind and river discharge have on SPM in a turbid estuary. It uses atmospherically corrected remotely sensed reflectances from Landsat-5, -7, and -8. From these data, we establish a 37-year-long time series, from 1984 to 2020, of satellite-derived SPM for the Scheldt Estuary. SPM was estimated using an algorithm applied to the near-infrared band and subsequently compared to in situ SPM data. Additionally, a time series of river discharge and wind speed were used to assess the frequency and severity of extreme events of wind speed and river discharge. In general, statistically significant but weak relationships between SPM and river discharge and between SPM and wind speed were observed. SPM correlated with river discharge and wind in large parts of the estuary, indicating the important role of these drivers in the entire estuarine system. Our study demonstrates how synoptic satellite snapshots can be combined with in situ time series of drivers, such as river discharge and wind, to capture where these drivers relate to (and likely affect) SPM within an estuary. However, our study demonstrates an inability to capture SPM during windstorms both from in situ and satellite data. We discuss the challenges and limitations of assessing the effects of extreme events from satellite and in situ SPM. We recommend the deployment of complementary moored turbidimeters for continuous observations at two strategic locations, as indicated by our spatial study, to improve the ability to capture the effects of extreme events in both space and time.

Texto completo da fonteResumo:
While the closure of theatres across Canada and around the world when the pandemic hit in March 2020 caused widespread feelings of loss amongst theatre practitioners and educators, the institutional pressures to find ways to survive and move on prevented many from processing their grief. This article examines The Stream You Step In (TSYSI), a series of four original Zoom plays co-produced by Outside the March and the University of Windsor in 2020, through the intersecting perspectives of pedagogy and grief. TSYSI was a response to grief on different levels: graduating students’ grief for their mainstage roles, which they had been working towards since entering the program but which they lost when the pandemic forced the cancellation of their planned theatre season; theatremakers, educators, and audiences’ collective grief for the loss of live theatre and the community it creates; and the grief experienced by society at large for the loss of Black and Indigenous lives, magnified in summer 2020 by the global outrage in response to the death of George Floyd and many others. Through reflection on two TSYSI plays, Karen Hines’s The River of Forgetfulness and David Yee’s good white men, this article stresses the importance of making space for grief within pedagogy. It argues that a grief-led creative process can honour what was lost, create and strengthen community, and foster opportunities to make new meaning. As theatres and educational and training institutions continue to face uncertainty, this article’s provocations contribute to ongoing conversations around ethics, representation, and collaboration in Zoom theatre.

The urban atmospheric boundary layer (UABL) is complex due to the heterogeneous underlying city surface. The nine anemometers installed at different heights along the 325 m meteorological tower provide an opportunity to carry out a refined study of wind properties in the UABL in central Beijing, China. Based on the recent 5-year high-resolution measured data, in total, 229,488 10-min length segments of wind records related to each anemometer are reliable for further analyses. Accordingly, the statistical properties of the wind speed and direction are first analyzed to present the local wind climate in a comprehensive way. Moreover, the pattern of the wind profiles related to two typical synoptic intense events are illustrated in order to give a preliminary perspective, then the statistical properties corresponding to a series of intense windstorms are described. Here, the deviations in the wind direction occur between 200 m and 280 m of the atmosphere, which might be due to the existence of an Ekman spiral; besides this, the laws of wind profiles based on open terrain are not suitable for the UABL, and the aerodynamic characteristic parameters of the UABL based on vertical stratified structures have to be considered. The results contribute to the establishment of revised models for the wind profile and are useful for the further understanding of the structure of UABL wind.

Abstract. After an overview of existing methods, we present a novel method of "event-adjusted" evaluation of extremeness of weather and climate events. It is based on optimization of both the considered area and the time duration for every event. The method consists of three steps: (i) estimation of return periods of a representative variable at individual sites, performed separately for various time windows; (ii) spatial interpolation of the point return period data; and (iii) searching the area and the time window in which the extremeness of the event was maximum. The extremeness is quantified as the common logarithm of the spatial geometric mean of the return periods multiplied by the radius of a circle of the same area as the one over which the geometric mean is taken. The maximum product is referred to as the weather extremity index (WEI). Two precipitation events, which affected the Czech Republic in May and in August 2010, were evaluated by the WEI for illustration. Validation of the method on sufficiently long data series is still needed. Moreover, the WEI is generally applicable regardless of the studied phenomenon (heavy rains, heat waves, windstorms, etc.). This makes it possible to study various weather and climate extremes from the viewpoint of possible recent and future changes in their frequency, seasonal distribution, and circulation conditions accompanying them.

Texto completo da fonteResumo:
The occurrence of extreme windstorms and increasing heat and drought events induced by climate change leads to severe damage and stress in coniferous forests, making trees more vulnerable to spruce bark beetle infestations. The combination of abiotic and biotic disturbances in forests can cause drastic environmental and economic losses. The first step to containing such damage is establishing a monitoring framework for the early detection of vulnerable plots and distinguishing the cause of forest damage at scales from the management unit to the region. To develop and evaluate the functionality of such a monitoring framework, we first selected an area of interest affected by windthrow damage and bark beetles at the border between Italy and Austria in the Friulian Dolomites, Carnic and Julian Alps and the Carinthian Gailtal. Secondly, we implemented a framework for time-series analysis with open-access Sentinel-2 data over four years (2017–2020) by quantifying single-band sensitivity to disturbances. Additionally, we enhanced the framework by deploying vegetation indices to monitor spectral changes and perform supervised image classification for change detection. A mean overall accuracy of 89% was achieved; thus, Sentinel-2 imagery proved to be suitable for distinguishing stressed stands, bark-beetle-attacked canopies and wind-felled patches. The advantages of our methodology are its large-scale applicability to monitoring forest health and forest-cover changes and its usability to support the development of forest management strategies for dealing with massive bark beetle outbreaks.

BACKGROUND Congenital duodenal webs are rare in adults and can lead to various symptoms such as nausea, vomiting, and postprandial fullness. The treatment for this disease is mostly surgical. Endoscopic treatment techniques have been developed and attempted for this disease. Endoscopic radial incision and cutting (RIC) techniques are reportedly very effective in benign anastomotic stricture. This case report highlights the effectiveness and safety of endoscopic RIC as a minimally invasive treatment for adult congenital duodenal webs. CASE SUMMARY A 23-year-old female patient with indigestion was referred to a tertiary hospital. The patient complained of postprandial fullness in the epigastric region. Previous physical examinations or blood tests indicated no abnormalities. Computed tomography revealed an eccentric broad-based delayed-enhancing mass-like lesion in the second portion of the duodenum. Endoscopy showed an enlarged gastric cavity and a significantly dilated duodenal bulb; a very small hole was observed in the distal part of the second portion, and scope passage was not possible. Gastrografin upper gastrointestinal series was performed, revealing an intraduodenal barium contrast-filled sac with a curvilinear narrow radiolucent rim, a typical "windsock" sign. Endoscopic RIC was performed on the duodenal web. The patient recovered uneventfully. Follow-up endoscopy showed a patent duodenal lumen without any residual stenosis. The patient reported complete resolution of symptoms at the 18-month follow-up. CONCLUSION Endoscopic RIC may be an effective treatment for congenital duodenal webs in adults.

AbstractA vortex in a wind field is an important aspect of a weather system; vortices often result in hazardous weather, such as rainstorms, windstorms, and typhoons. As the availability of numerical meteorological data increases, traditional manual analysis no longer provides an efficient means of timely analysis of observed and predicted atmospheric vortices. Therefore, a method was proposed to automatically characterize flow patterns of vortices and to detect the centers of vortices in complex wind fields generated from numerical weather prediction (NWP) models. First, a statistical feature was developed to preliminarily filter regional wind data to obtain (anti)cyclonic vortices. Second, flow patterns of ideal axisymmetric wind fields were extracted by analyzing circular data related to wind directions. Third, for actual vortices in a complex wind field, a series of rules and deformation degree indices were constructed to retrieve the provisional centers of vortices. Fourth, the Ward hierarchical clustering algorithm was used to cluster these provisional centers, which were filled up by a dilation operation to cover the core region of the vortex. Finally, the vortices were classified as either cyclones or anticyclones based on their analyzed vorticity, and their global centers were precisely located. Experimental results show that the proposed preprocessing method was more effective than the traditional filtering method and that the features of the flow pattern were stable regardless of the variety in the resolution and scale. It was also proven that the proposed method can be further extended and applied to detecting typhoon centers, for which it was more effective than other currently used methods.

The North American Derecho of 29–30 June 2012 exhibits many classic progressive and serial derecho features. It remains one of the highest-impact derecho-producing convective systems (DCS) over CONUS since 2000. This research effort enhances the understanding of the science of operational forecasting of severe windstorms through examples of employing new satellite and ground-based microwave and vertical wind profile data. During the track of the derecho from the upper Midwestern U.S. through the Mid-Atlantic region on 29 June 2012, clear signatures associated with a severe MCS were apparent in polar-orbiting satellite imagery, especially from the EPS METOP-A Microwave Humidity Sounder (MHS), Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager Sounder (SSMIS), and NASA TERRA Moderate Resolution Imaging Spectroradiometer (MODIS). In addition, morning (descending node) and the evening (ascending node) METOP-A Infrared Atmospheric Sounding Interferometer (IASI) soundings are compared to soundings from surface-based Radiometrics Corporation MP-3000 series microwave radiometer profilers (MWRPs) along the track of the derecho system. The co-located IASI and MWRP soundings revealed a pre-convective environment that indicated a favorable volatile tropospheric profile for severe downburst wind generation. An important outcome of this study will be to formulate a functional relationship between satellite-derived parameters and signatures, and severe convective wind occurrence. Furthermore, a comprehensive approach to observational data analysis involves both surface- and satellite-based instrumentation. Because this approach utilizes operational products available to weather service forecasters, it can feasibly be used for monitoring and forecasting local-scale downburst occurrence within derecho systems, as well as larger-scale convective wind intensity associated with the entire DCS.

Introduction Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Several methods have been proposed for repairing a distal penile erosion. We present our preliminary experience in “Distal corporoplasty” technique. Methods We enrolled 18 consecutive patients whose underwent a distal corporoplasty with simultaneous reimplantation of an “AMS 700 inflatable penile prosthesis (LGX)” from January 2013 to November 2015 at our hospital. All procedures were performed by a single surgical team. Intraoperative and postoperative complications have been classified and reported according to Satava6 and Clavien-Dindo (CD) system.7 Mean values with standard deviations (±SD) were computed and reported for all items. Results Mean age of the patients was 53.61 (±11.90) years. Mean body max index (BMI) was 24.22 (±2.51). Mean operative time was 85.2 (±13.1) minutes. Blood losses were minimal. No intraoperative complications are reported according to Satava classification. Four out of 18 patients (22.22%) experienced postoperative complications according to CD system. All patients had sexual intercourse for the first time postsurgery after a mean of 59.11 ± 2.08 days. Mean follow-up was 22.11 (±9.95). Discussions Distal extrusion of cylinders is a potential complication of the penile prosthesis implantation. Distal corporoplasty was first described by Mulcahy. He reported a series of 14 patients with a follow-up of about 2 years with optimal functional outcomes. Moreover, distal corporoplasty resulted in shorter operative time, better function, less pain, and fewer recurrences than Gortex windsock repair.10 In our experience, distal corporoplasty is a simple and safe procedure in the treatment of distal cylinders extrusion when the prosthetic material is not exposed to the exterior.

Abstract On 22 May 2008, a strong tornado—rated EF3 on the enhanced Fujita scale, with winds estimated between 136 and 165 mi h−1 (61 and 74 m s−1)—caused extensive damage along a 55-km track through northern Colorado. The worst devastation occurred in and around the town of Windsor, and in total there was one fatality, numerous injuries, and hundreds of homes significantly damaged or destroyed. Several characteristics of this tornado were unusual for the region from a climatological perspective, including its intensity, its long track, its direction of motion, and the time of day when it formed. These unusual aspects and the high impact of this tornado also raised a number of questions about the communication and interpretation of information from National Weather Service watches and warnings by decision makers and the public. First, the study examines the meteorological circumstances responsible for producing such an outlier to the regional severe weather climatology. An analysis of the synoptic and mesoscale environmental conditions that were favorable for significant tornadoes on 22 May 2008 is presented. Then, a climatology of significant tornadoes (defined as those rated F2 or higher on the Fujita scale, or EF2 or higher on the Enhanced Fujita scale) near the Front Range is shown to put the 22 May 2008 event into climatological context. This study also examines the communication and interpretation of severe weather information in an area that experiences tornadoes regularly but is relatively unaccustomed to significant tornadoes. By conducting interviews with local decision makers, the authors have compiled and chronicled the flow of information as the event unfolded. The results of these interviews demonstrate that the initial sources of warning information varied widely. Decision makers’ interpretations of the warnings also varied, which led to different perceptions on the timeliness and clarity of the warning information. The decision makers’ previous knowledge of the typical local characteristics of tornadoes also affected their interpretations of the tornado threat. The interview results highlight the complex series of processes by which severe weather information is communicated after a warning is issued by the National Weather Service. The results of this study support the growing recognition that societal factors are just as important to the effectiveness of weather warnings as the timeliness of and information provided in those warnings, and that these factors should be considered in future research in addition to the investments and attention given to improving detection and warning capabilities.

Theoretical basis This case has three primary objectives. First, it allows students to think through a conceptual cost and benefit analysis associated with the decision-making process in line with basic economic thinking. Students will revisit core concepts of marginal benefit vs marginal cost, the notion of opportunity costs and the role of sunk costs in this type of analysis, while also highlighting the nature of market structure, oligopolies and competition across firms in an industry. The second goal of this case is to consider the role of business ethics in the DC-10 case: specifically, to consider the potential influence of moral awareness and moral disengagement in unethical decisions made by McDonnell Douglas. Students will develop an understanding of these concepts and solidify their learning by applying them to the case and engaging in active discussion. Finally, the third goal of the case allows students to explore organizational culture and specifically offer recommendations for organizations thinking about the link between decision-making, the role of ethics and culture. Research methodology The technical reports released by the National Transportation Safety Board along with secondary data such as available public data such as news reports were used to round out the synopsis of the case study. Case overview /synopsis This case explores the accidents of two McDonnell Douglas DC-10s in the early 1970s at the onset of the jumbo jet race between Boeing, Lockheed and McDonnell Douglas. It explores the series of events during the “Windsor Incident” in 1972 and the subsequent accident over Paris in 1974. It explores the reasons why the cargo door on the DC-10 was faulty and subsequently why the door was not fixed. It examines the interplay of industry suppliers such as McDonnell Douglas and how they interact with oversight authorities such as the Federal Aviation Authority. The Teaching Note focuses on the economic thinking at McDonnell Douglas, behavioral ethics and organizational culture. Complexity academic level This case is best explored over a 90 min session but could be expanded to take up one 3 h session. The authors have used this case format in an undergraduate organizational behavior class, an MBA Leadership and Organizational Change class, and an MBA Economics of Managers class. It works particularly well in the MBA setting, as students with work experience can see the links between the mistakes made by McDonnell Douglas and their workplaces.
