Biodiversity of epiphytic lichens and air pollution in the town of Siena (central Italy)
No full textThe results of a biomonitoring survey carried out in the town of Siena (central Italy) using the biodiversity of epiphytic lichens as indicator of air pollution are reported. The general picture was rather good, with more than 60% of the study area being in the categories "semi-natural" or "natural" according to a calibrated scale of environmental naturality/alteration. Compared with the situation of 1995, ameliorating conditions were found as a result of an improvement in air quality over time

Full text linkWe present new data on the distribution of five orchid species in the Batova
Valley Protected Area BG 0000102, part of the European ecological network Natura 2000.
Although these orchid species are not new to the floristic region of Northeastern Bulgaria, we report new habitats in Batova River Valley Protected Area. Three of the species are reported for the first time, for the other two species, this is the second report in the study area. All described orchid species are subject to protection by various national and international documents

Study of the current status of traditional knowledge about herbs and their use among the population of THE Northern Bulgarian Black sea coast
No full textRecent ethnobotanical studies in different parts of the world indicate a trend of gradual reduction of the folk knowledge about herbs and their use. The aim of our study was to examine the current state of that knowledge and the attitude to traditional methods of treatment among the population of the Northern Bulgarian Black sea coast. The study was carried out in different cities and villages from April to June 2015 using the interview technique face to face. Respondents were men and women of different social status and of different age groups, randomly selected.Descriptive statistical procedures and χ2 test were used for the analysis of results. The impact of demographic characteristics on the attitudes of respondents to the herbs and their use was examined by the correlation coefficient of Pearson.Positive attitude to herbs and their uses were established for 96.85% of respondents, and only 4.32% were indifferent. Among the demographic characteristics only age and gender were ones that affected the answers. The highest percentage of negative responses to the question „What is your attitude to herbal preparations compared to those of conventional medicine,“ was given by people from younger age categories, which outlined the trend of reduced interest to herbs and herbalism among the younger generation. The majority of respondents - 76.68% preferred combined therapy with herbs and synthetic drugs. Relatively large was the share of those who replied entirely on herba treatment - 29.19%. The results indicated consistent positive attitude of the local population of Northern Bulgarian Black sea coast to medicinal plants and to the traditional methods of treatment. Along with this the impact of modernization of the society on the use of herbs is proven
Dobri teolog Galileo Galilei
Full text linkThe article focuses on Galileo’s understanding of the relationship between revealed and natural truth. In his Letter to Castelli Galileo argued for the separation of theology and natural philosophy. But in the very same letter and in Letter to Dini he appears to use the Bible as a scientific authority, in support of his Copernican views, and thus he seems to contradict his own hermeneutical principles. The author argues that Galileo’s Copernican interpretation of Psalm 18 in Letter to Dini should be understood against the background of Galileo’s argumentation in Letter to Castelli in which Galileo also interpreted a passage from Joshua and that both letters cannot be properly understood without knowledge and understating of the context of their genesis. Galileo’s position is not contradictory but consistent. The second aim of the article is to underline the fact that in these two letters Galileo develops a specific philosophy of nature in order explain his telescopic observations and discoveries on a more fundamental philosophical level.Članek se osredotoča na Galileijevo razumevanje razmerja med razodeto in naravoslovno resnico. Galilei je v Pismu Castelliju zagovarjal ločevanje med teologijo in naravoslovnim raziskovanjem, vendar pa je v tem istem pismu in Pismu Diniju Biblijo bral kot kopernikansko besedilo in tako – vsaj na prvi pogled – nasprotoval svojim lastnim načelom in hermeneutičnim postulatom. Avtor zagovarja tezo, da je treba Galileijevo kopernikansko interpretacijo Psalma 18 v Pismu Diniju razumeti na podlagi argumentacije, ki jo je razvil v Pismu Castelliju, v katerem je tudi interpretiral pasus iz Jozuetove knjige, obe pismi pa je nemogoče razumeti brez poznavanja in razumevanja konteksta, v katerem sta nastali. Ta pa ni samo teološki, temveč predvsem naravosloven. Po avtorjevem mnenju Galileijevo stališče in argumentacija nikakor nista protislovna, temveč konsistentna. Drugi cilj članka je opozoriti na dejstvo, da Galilei v teh dveh pismih razvije zametek specifične filozofijo narave, s katero skuša svoja teleskopska odkritja pojasniti na bolj temeljni filozofski ravni
