    Tulbure C., Duduman G., 2012. A conversion method of young hornbeam coppices and its possible impact on future stand structural attributes. Ann. For. Res. 55(2): 281-296, 2012. Abstract. The paper analyse the substitution of hornbeam coppice stands and conversion into high forest stands, formed by species that better valorise the site conditions. An improved alternative for the method of substitution in corridors is presented. The main goal of this new substitution-conversion alternative is to gradually conduct the actual structure of the coppice stands towards the target structure imposed by the forest management objectives, without a total elimination of the species that will be substituted. Two plot areas were selected in order to put into practice the proposed method. Bands were created for reducing the effective costs of the substitution process. 450 respectively 468, small seedlings (of beech, pedunculate oak and sessile oak) per hectare were planted in the created bands. The planting scheme took into account the shadow tolerance of the species from the target composition. Based on the field data and using the yield tables, the evolution of the stands in the two selected plots was simulated. In this respect, the forest treatments were parameterized according to the Romanian forest rules regarding the application of thinning and regeneration cuttings. The substitution-conversion process started from an almost pure hornbeam coppice and, simulating the application of the proposed method for 120 years, it was predicted that the method allows directing the actual stand structure to the target structure. The dynamics of species and structural diversity were assessed and the results of 120 years simulation indicate an important increase of both the species (the Shannon species index increases from 0.203 to 1.073) and structural diversity (the Gini structural index increases from 0.032 to 0.200)

    Department of Obstetrics and Gynecology, Nicolae Testemitanu State Medical and Pharmaceutical UniversityFetal intrauterine growth retardation (IUGR) represents one of the most important problems in contemporary obstetrics and perinatology. IUGR represents an polyetiologic condition, frequently being observed the association of various genesis factors. One of the leading causes of this pathological process is structural and functional changes in the placental complex, which involves alterations in utero-placental and feto-placental circulation. The study was performed on a sample of 610 cases of patients diagnosed with IUGR. It aims to highlight the influence of placental complex changes on the pathological process.Задержка внутриутробного развития плода (ЗВРП) представляет собой одну из самых важных проблем в области современного акушерства и перинатологии. ЗВРП является полиэтиологическим процессом при котором часто наблюдается ассоциация факторов различного генезиса. Oдна из главных причин ведущих к проявлению патологического процесса представленна структуральными и функциональными изменениями плацентарного комплекса, что способствует изменению в маточно-плацентарном и фето-плацентарном кровотоках.

    Department of Obstetrics and Gynecology, Nicolae Testemitsanu State University of Medicine and Pharmacy, Chisinau, the Republic of MoldovaBackground: The birth of children with extremely low weight (500-1000 g) is an important problem, which is caused by the combination of numerous ethiopathogenetic factors. In 35% of cases the genesis is difficult to be assessed. In these situations it is extremely important to diagnose and prevent a prematurity in order to prolong the pregnancy and decrease the perinatal risk indicators. Material and methods: The study has been conducted on a total of 331 cases, including the research of some aspects of diagnosis and conduct of children with extremely low birthweight. The following diagnostic steps have been taken: screening for TORCH complex infections, the analysis of bacteriological discharges from vagina and of urine, ultrasound examination (cervical length, fetal biometry and placental complex condition), macroand microscopic examination of placenta. Results: The women, who have given biths to the children with birth weight of 500-1000 g, had the pregnancy complicated by exacerbation of somatic diseases, TORCH complex infections, bacterial vaginosis, hypertensive conditions, the premature rupture of membranes and fetal and placental pathology. Conclusions: The ultrasound assessment of the cervical length along with the clinical expression of imminent termination of the pregnancy are important diagnostic and prognostic markers, allowing the inclusion of pregnant women into the risk group and the determination of the potential risk of delivering children with the birth weight of 500-1000 g. The authors have analyzed the influence of extremely low birth weight on perinatal indicators, its influence on the degree of prematurity, the connection of the birth weight and maternal and/or fetal concomitant pathology. An important aspect is the involvement of doctors in the process of the delivery of children with the birth weight of 500-1000 g, so that all suspected cases can be considered, a step that will prevent the excessive expectations concerning the perinatal indicators and will allow the survival of children with subsequent high potential of life quality

    Preconceptional care: opportunities and challenges

    Get PDF
    The aim of the study was to identify the opportunities required for straightening of preconceptional health and care, according to medical literature. Benefits and potential risks were mentioned. Some international experiences related to preconceptional care management were analyzed, by making references especially to those from US, including the actions initiated by Centers for Disease Control and Prevention (CDC). In this article the WHO position is mentioned which develops a global consensus on preconceptional care to reduce maternal and childhood mortality and morbidity, proving a "menu of interventions" which lists the health problems, behavioral problems and risk factors in thirteen domains, evidence-based interventions to address them and mechanisms of delivering them. A special section is dedicated to some controversies in preconceptional care management, priority at the medical primary care. The WHO recommendations and the international experience represent a good support for health care systems from different countries to improve the access to the care before getting pregnant and overcoming inequalities. In this context, authors consider that the improving of preconceptional care in each country depends, first of all, on the wish of governors and health care providers. In conclusion, the hypothesis to review the family planning concept is suggested, considering that it has equally to include two main components - contraception and preconceptional care. It will provide real opportunities for people to achieve their reproductive life plan to have not only wanted, but also healthy children

    Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

    Get PDF
    This paper presents measurements of the W+μ+νW^+ \rightarrow \mu^+\nu and WμνW^- \rightarrow \mu^-\nu cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

    Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

    Get PDF
    A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

    Data on lithofacies, sedimentology and palaeontology of South Rifian Corridor sections (Morocco)

    Get PDF
    We provide lithological, sedimentological and micropalaeontological descriptions of 39 sections and boreholes crossing the upper Miocene deposits of the Rifian Corridor. These deposits represent the sedimentary remnants of the marine gateway that connected the Atlantic to the Mediterranean in the late Miocene. Results from these 39 sites were adopted to reconstruct the palaeogeographic evolution of the gateway presented in the associated research article (Capella et al., 2018) [1]. For each outcrop we present a synthesis of field observations, lithofacies, key sedimentological features, planktic and benthic assemblages

    Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

    Get PDF
    Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
