This study presents the results of a landslide susceptibility analysis applied to Vrancea-Buzău seismogenic region in Carpathian Mountains, Romania. The target area is affected by large diversity processes. Slopes are made-up various types rocks, climatic conditions can be classified as wet, and seismically active one. All this contributes observed high hazard. paper analyses spatial component ...
In the face of environmental change, species can evolve new physiological tolerances to cope with altered climatic conditions or move spatially to maintain existing physiological associations with particular climates that define each species' climatic niche. When environmental change occurs over short temporal and large spatial scales, vagile species are expected to move geographically by track...
Climatic extreme events can cause the shift or disruption of plant-insect interactions due to altered plant quality, e.g. leaf carbon to nitrogen ratios, and phenology. However, the response of plant-herbivore interactions to extreme events and climatic gradients has been rarely studied, although climatic extremes will increase in frequency and intensity in the future and insect herbivores repr...
Knowledge of the relationships between environmental forcing and demographic parameters is important for predicting responses from climatic changes and to manage populations effectively. We explore the relationships between the proportion of sea cows (Dugong dugon) classified as calves and four climatic drivers (rainfall anomaly, Southern Oscillation El Niño Index [SOI], NINO 3.4 sea surface te...
حوضه آبخیز سیاهرود در بخش رحمت آباد شهرستان رودبار گیلان قرار دارد. که مساحت این حوضه 110 کیلومتر مربع است. هدف از این تحقیق بررسی پتانسیل زمین لغزش و پهنه بندی آن به روش ahp در سطح حوضه می باشد که با استفاده از عکس هوایی، نقشه های زمین شناسی و توپوگرافی و پیمایش صحرایی پراکنش زمین لغزش ها در گستره ی مورد مطالعه مشخص می گردد. از این رو در این تحقیق نقشه های مربوط با استفاده از سیستم gis تهیه و ...
the present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in ghana. heavy metal concentrations in all samples were generally within the who safe limits with the average activity concentrations of 238u, 232th, and 40k in water being respectively 0.42±0...
introduction: the majority of leukemia patients are acute leukemia patients, so that about 70.8% lymphoblastic leukemia were acute lymphoblastic leukemia (all) patients and 66.4 % of myeloid leukemia patients were acute myeloid leukemia (aml) in tehran metropolitan. during the last two decades, intensification of therapy by the use of high-dose cytarabine allogeneic stem cell transplantation in...
admitted that this was true in the case of many of our foreign stations. Thus, the death-rate of the British soldier in India averaged (up to 1855) 69 per 1,000, the rate at home being 9 per 1,000 among men at the soldier's age. But when the causes of this high mortality were enquired into, it was found that by far the largest number of deaths were due to a few diseases of the zymotic class; so...
This work develops Artificial Neural Networks (ANN) models applied to predict the consumption forecasting considering climatic factors. It is intended to verify the influence of climatic factors on the electricity consumption forecasting through the ANN. The case study is applied in the Campinas city, Brazil. This work used Perceptron and Backpropagation ANN models. The specific goal is compari...
We are limited in our ability to predict climate-change-induced range shifts by our inadequate understanding of how non-climatic factors contribute to determining range limits along putatively climatic gradients. Here, we present a unique combination of observations and experiments demonstrating that seed predation and soil properties strongly limit regeneration beyond the upper elevational ran...
