Os autores fazem o relato de três casos clínicos: Papilomatose florida, Epitelioma cuniculatum e Condiloma gigante Buschke Lowenstein, considerados como representativos entidades que compõem grupo das Papilomatoses pseudo-carcinomatosas. São favoráveis à conceituação pseudo-carcinomatosas apoiando-se na semelhança clínica, histopatológica, evolutiva da terapêutica a ser instituída. Discutem, ai...
In this paper, we present the results of mercury concentration in soils, buds and leaves of maple (Acer platanoides-Ap) and linden (Tilia platyphyllos-Tp) collected in four periods of the growing season of trees, i.e. in April (IV), June (VI), August (VIII) and November (IX) in 2013, from the area of Poznań city (Poland). The highest average concentration of mercury for 88 samples was determine...
In this paper, we study the theory of pseudo knots, which are knots with some missing crossing information, and introduce tied links knotoids. particular, first present a braiding algorithm for then L-moves in that setting, use formulate sharpened version analogue Markov theorem braids. Then, links, generalize notion exploit relation between singular links. We an L-move braid equivalence monoid...
چکیده: به منظور بررسی روند، میزان و موقعیت تخریب گستره جنگل در یک دوره 50 ساله تحقیقی در قسمتی از جنگل های کاکارضای شهرستان خرم آباد با مساحت 65/5090 هکتار انجام گرفت. برای مدلسازی احتمال تخریب و کاهش گستره جنگل با عوامل فیزیوگرافی شامل شیب، ارتفاع و جهت دامنه و متغیرهای اقتصادی- اجتماعی شامل درصد باسوادی، میزان جمعیت، نوع معیشت، و فاصله از جاده، رودخانه، روستا، مناطق جنگلی و غیرجنگلی از رگرسی...
To assess potential forest compositional responses to exchangeable soil calcium (Caexch) and aluminum (Alexch), we characterized light-dependent growth and mortality of tree seedlings under amendments of CaCl2 and AlCl3 at Hubbard Brook Experimental Forest (HBEF), New Hampshire, U.S.A. Seedlings of Acer saccharum Marsh., Fagus grandifolia Ehrh., Betula alleghaniensis Britton, Abies balsamea (L....
Montane forests in the northeastern United States have experienced symptoms of declining vigor, such as branch dieback and increased mortality, over the last half-century. These declines have been attributed to the cumulative impacts of acid deposition, but reconstructing these declines from tree-ring records has proved difficult because of confounding factors that affect low-frequency growth p...
Crown encroachment by trees surrounding newly formed gaps reduces their size, a fact that may cause error in area-based analyses of rate of gap formation and disturbance intensity. Generally, an estimate of proportional area occupied by age classes within a stand of trees can be obtained by determining the age of a selected canopy tree nearby each of randomly or uniformly located sample points....
