Unlike the contiguous windthrows, the diffuse windthrows occurred as a result of wind gusts of lower speed (100-140 km/h) than in the first case (>140 km/h) are much more difficult to detect due to their much lower areas and due to their very large number, of several hundreds in the wooded mountain massifs. The objective of this research is to present a rapid procedure for the detection of the diffuse windthrows based on low cost, Landsat type images, knowing that certain sensors cannot be accessed without significant investments. Our application is based on the study of effects caused by the Xynthia storm in the Vosges Mountains in the North-East of France, on 28 February 2010. Thus, based on two sets of Landsat satellite images, we used the “dark object” approach and the Disturbance Index, as well as a classification of the images before and after the storm, resulting in a change map. Following the detection process, 257 scattered polygons were detected, totalling 229 ha. For validation purposes, high-resolution images and orthophotoplans taken before and after storm were used. The error matrix was calculated, achieving an overall accuracy of 86%, which confirms the quality of our analysis and supports this procedure for detecting diffuse windthrow based on low cost resources.

Abstract The floods that Algeria has experienced in recent years are among the most significant natural disasters recorded by the country. These disasters, whose amplitude and frequency have tended to become increasingly irregular in space and time, in the current context of global climate change, encourage us to improve our flood management and forecasting strategies, notably through the re-evaluation of protection structure capacities, designed on the basis of hydrological data analyzed by statistical adjustment of past rainfall hazards. The objective of this study is to develop a minimalist conceptual numerical model for flood forecasting and management under GIS environment for the north-east region of Algeria. This model was developed by analyzing hydrographic data that can be adapted to climate data collected in real time, to predict short-term flood hydrographs in all segments of the hydrographic network, based on the Sokolovsky model for construction of synthetic hydrographs, combined with the Horton architecture for basin discretization. We obtained accuracy on past rainfall hazard simulations around 65.2% for peak flow amplitudes and 88.3% for surface runoff base times. This low-cost simple model opens the way to more possibilities in flood management, and can be improved through better spatialization and calibration with more field data.

Taxonomic Studies

In 1996 a sponge was found in a well studied area in the Ria of Etel, Brittany, France, that had never been recorded there before. This sponge was later described as a new species and genus,Celtodoryx girardaeby Perezet al.(2006), who concluded that it is probably an invasive species. Over several yearsC. girardaewas found to occur successively in the Gulf of Morbihan, France, and Oosterschelde estuary, Netherlands. This sponge is characterized by an extensive spatial broading and therewith it rates today among the dominant benthic megafauna in the shallow waters of the Gulf of Morbihan and Dutch inshore waters. During our recent survey of the Chinese Yellow Sea sponge fauna, we found an abundant species with close morphological similarities toC. girardae. Further taxonomic studies have revealed that both the Chinese and European sponges are in fact conspecific withCornulum ciocalyptoidesdescribed by Burton (1935) from Posiet Bay, Sea of Japan and later recorded from other localities of the North West Pacific (e.g. Koltun, 1971; Sim & Byeon, 1989). In this paper we transfer the species of Burton fromCornulumtoCeltodoryxand consequently it becomes the senior synonym ofC. girardae. Furthermore, we conclude thatCeltodoryx ciocalyptoideswas introduced to the North East Atlantic from the North West Pacific with aquaculture of the Pacific oysterCrassostrea gigasas the probable vector. This is probably the first case recorded so far of a sponge species being transferred from one ocean to another by human activity.

The Thamirabarani River is one of the prominent sources of water for Kadamba Tank. Thamirabarani river is the perennial river in the South Tamil Nadu. Apart from that, which can store water during the North-East Monsoon period. The water user association members are getting money from duck rears and allowing duck into the agriculture fields after the harvest. The agriculturist is saying that after the first harvest if the water is not sufficient for the next crop such as paddy, farmers can go for the crop such as zero water consumption crops like green gram, black gram. Because of duck farming, agriculturists are not able to get benefited from low-cost crops. Indeed, water is the scarcity of resources in Tamil Nadu; irrigation water should not be charged more. Like other places in Tamil Nadu, in Kadamba Kulam agriculture basin, also collecting charges (ayakatu) for water usage by the association. The nonavailability of water throughout the year, the agricultural labors are moved from native and employed in the industrial sector. Tamil Nadu is a water tense state that lingers to experience water shortages which are expected to exacerbate in future due to the political pressure and money laundering, Justices A. Selvam and P. Kalaiyarasan dismissed the petitions on several grounds, including the State government’s submission that only 43 mc ft out of 5,049 mcf of surface water that goes waste into the sea was being supplied to the two industries. The court said that such supply did not affect either irrigation or drinking water needs of the people in any way.

The six months following the Anglo-Irish treaty of 1921 saw an appalling level of violence in Belfast and on the border, which threatened the stability of the newly formed Northern Ireland government. Official figures for the period between 6 December 1921 and 31 May 1922 listed seventy-three protestants and 147 catholics killed in Belfast and eight protestants and twenty-two catholics killed in the six counties outside Belfast. In that period two wide-ranging agreements aimed to reform the northern government and security system: they became known, somewhat inaccurately, as the Craig-Collins pacts, of 21 January and 30 March 1922. This article discusses the motivation behind the pacts and the reasons for their failure in a wide context, by giving equal weight to the attitudes of the British government and to opinion on both sides of the Irish border.The Northern Ireland government was established in 1920–21. It was unrecognised by the dáil government in the south and by much of the northern catholic minority. The province developed against a background of violence and upheaval, including the expulsion of catholic shipyard workers from their work in the summer of 1920; the dáil retaliated by boycotting Belfast goods. The period also saw increasing I.R.A. activity in the north during the latter stages of the Anglo-Irish war, and the five-month truce that followed it. Though the northern government was not a party to the treaty negotiations, only reluctantly accepting the granting of dominion status to the south, the months before and after the settlement greatly increased tensions in the north-east.

Independent component analysis (ICA) is one of the most effective approaches in extracting independent signals from a global navigation satellite system (GNSS) regional station network. However, ICA requires the involved time series to be complete, thereby the missing data of incomplete time series should be interpolated beforehand. In this contribution, a modified ICA is proposed, by which the missing data are first recovered based on the reversible property between the original time series and decomposed principal components, then the complete time series are further processed with FastICA. To evaluate the performance of the modified ICA for extracting independent components, 24 regional GNSS network stations located in North China from 2011 to 2019 were selected. After the trend, annual and semiannual terms were removed from the GNSS time series, the first two independent components captured 17.42, 18.44 and 17.38% of the total energy for the North, East and Up coordinate components, more than those derived by the iterative ICA that accounted for 16.21%, 17.72% and 16.93%, respectively. Therefore, modified ICA can extract more independent signals than iterative ICA. Subsequently, selecting the 7 stations with less missing data from the network, we repeatedly process the time series after randomly deleting parts of the data and compute the root mean square error (RMSE) from the differences of reconstructed signals before and after deleting data. All RMSEs of modified ICA are smaller than those of iterative ICA, indicating that modified ICA can extract more exact signals than iterative ICA.

ABSTRACTBackgroundWe evaluated how effective an advertising campaign that was piloted by Cancer Research UK in January/February 2018 was at promoting quit attempts by increasing awareness of the relative harms of e-cigarettes compared with smoking.MethodsAdults (≥16 years, n = 2217) living in Greater Manchester (campaign region) and Yorkshire & Humber and the North East of England (control regions) completed cross-sectional surveys immediately before and after the campaign period. Surveys measured socio-demographics, perceptions and use of e-cigarettes, and motivation and attempts to quit smoking. We tested interactions between time (pre, post) and region (campaign, control).Results36.7% (95% CI 33.0% – 40.6%) of those in the intervention region recognised the campaign. In the general population, interactions were non-significant for all outcomes except for perception of e-cigarettes as effective cessation aids, with smaller increases from pre-to post-campaign in the campaign (49.9% to 54.0%) compared with the control region (40.5% to 55.0%; OR = 0.66, 95% CI 0.45 – 0.98). Among smokers, motivation to quit increased in the intervention region (44.0% to 48.0%) but decreased in the control region (40.5% to 21.5%; OR = 2.97, 95% CI 1.25 – 7.16), with no other significant differences between regions over time. A Bayesian analysis confirmed that non-significant results were inconclusive.ConclusionsCompared with the control region, the campaign was associated with an increase in smokers’ motivation to quit but a smaller increase in adults’ perception of e-cigarettes as an effective cessation aid. There was insufficient evidence to determine whether the campaign affected other outcomes.

The COVID-19 pandemic has affected millions of people, and some researchers postulate that a mental health crisis will follow. The immediate effects of the COVID-19 pandemic on children’s mental health are now starting to be published, and results appear to be mixed. There is no research, to the authors’ knowledge, that empirically examines the functioning of young people following intervention from Child and Adolescent Mental Health Services (CAMHS) Crisis Teams in the UK during the COVID-19 pandemic. This service evaluation aims to do this using data from an NHS trust that supports 1.4 million people in the North East of England. We compared functioning, as measured by the Outcome Rating Scale (ORS), before and after treatment for young people discharged from the CAMHS Crisis Team between December 2019 and December 2020. ORS scores were significantly higher at the end of treatment (t(420) = −57.36, p < 0.001) with a large effect size (d = −1.56). Fifty eight percent of patients exhibited significant and reliable change (i.e. functioning improved to a ‘healthy’ level). No patients significantly deteriorated in functioning after accessing the crisis service.

AbstractBackgroundThe goal of the present prospective study was to assess health-related quality of life in children and adolescents with CHD before and after cardiac catheter treatment.MethodsThe study enrolled 96 children/adolescents with CHD from the north-east of China who underwent cardiac catheter intervention treatment between March, 2013 and January, 2014. The health-related quality of life at 24 hours before treatment, 1 month after treatment, and 6 months after treatment was evaluated using Pediatric Quality of Life Inventory Measurement Models 4.0 (PedsQLTM 4.0) generic core scales, and the scores were further compared.ResultsBefore treatment, each HRQOL domain score and the total score were obviously decreased than the post-treatment scores (1 month and 6 months). The total score and the scores in physical functioning and psychological functioning components were further increased 6 months after treatment than the scores 1 month after treatment.ConclusionThe present study suggests that cardiac catheter interventional treatment improves the life quality of children or adolescents with CHD as time increases after the intervention.

Territorial Organization

With the conquest of the Iberian Peninsula by the Roman Empire, the different societies in the north, north-west, north-east, east, and centre were grouped into the same province, Hispania Tarraconensis. This article sets out to assess whether this new, Roman, territorial organization affected previous animal husbandry and hunting practices. The taxonomic and osteometric study of faunal remains from ninety-four sites dated between the fifth century bc and third century ad provides an overview of animal husbandry and hunting before and after the Roman conquest. It shows that important changes took place and that this province was differentially exploited in terms of animal husbandry.
