THE INCIDENCE OF NEW ECOSYSTEMS (EE – EMERGING ECOSYSTEMS) IN THE KARST BIOSPHERE RESERVE : GROUP PROJECT, FINAL REPORT
Klemen Cotič, Matej Pogorelc, Matjaž Reya, Barbara Šavli, Nika Feigina, Merisa Kapić, Ӧzkan Karaçam, Mariya Perepelytsya, 2017, druge monografije in druga zaključena dela

Opis: The need of wood for building and heating, the extensive grazing and population growth in the 18th and 19th centuries led to turning the Karst area in Slovenia into a bare land. In the 19th century organised reforestation started which was successfully performed with Black pine (Pinus nigra J. F. Arnold). Later on, the reforestation was replaced by the process of spontaneous afforestation. The successfulness of reforestation with Black pine also made it possible for the native tree species to grow. The abandoning of the use of agricultural land also contributes to the spontaneous afforestation. In this project we determined the changes in forest cover through time. We used aerial photographs from the years 1957, 1975, 1985 and 2015. By drawing polygons on the maps in the QGIS programme on the areas that are covered with forests, are overgrown or are used for agricultural purpose we compared the areas from the maps of different years. We found out that the area covered with forest had increased by more than 50 % from the year 1957 to 2015. The increase in the area of forest cover due to afforestation provides new habitats for fauna and flora to live in.

Zaprtozančno vodenje več-conske peči za kaljenje jeklenic
Matej Gabrijelčič, 2016, magistrsko delo

Opis: Več-conske peči za kaljenje jeklenic se v jeklarstvu uporabljajo za izboljševanje mehanskih lastnosti jeklenic. Peč je sestavljena iz več con, v teh spreminjamo temperature z odprtostjo ventilov dovoda energenta za ogrevanje in tako sledimo predpisanim temperaturam iz diagrama procesa kaljenja. Če odprtost ventila za ogrevanje posamezne cone peči vodimo ročno, se lahko zaradi zunanjih motenj pojavi problem pri medsebojnem vplivu sprememb temperatur v conah. To povzroči slabe mehanske lastnosti jeklenic, strošek segrevanja peči se poveča, ob tem pa imamo zagotovljeno tudi slabo varnost ročno vodenega procesa. Opisane slabosti ročno vodenega procesa rešimo z avtomatsko regulacijo. Izbrali in ovrednotili smo metodo vodenja več-conske jeklarske peči za kaljenje jeklenic in pokazali ekonomsko upravičenost avtomatske regulacije. Ugotovili smo, da avtomatsko voden proces sledi zahtevam po ustrezni temperaturi v posamezni coni peči − glede na diagram kaljenja jeklenic −, je varnejši od ročno vodenega, strošek njegove vpeljave pa se povrne v kratkem časovnem obdobju. Zaključimo lahko, da je ustrezno voden proces zanesljiv in velikokrat ponovljiv, predstavlja tisti proces, ki pošilja ustrezne informacije regulatorju procesa preko povratne zanke o tem, kaj se dogaja v posamezni coni peči za kaljenje jeklenic.

Poljedelsko društvo kolonov in malih posestnikov v Fojani
Matej Debenjak, 2016, diplomsko delo

Opis: Kolonat se je v Goriških brdih ohranil do konca štiridesetih let 20. stoletja. Koloni so pripadali starim fevdalnim družinam, slovenskim in italijanskim veleposestnikom, župnijam, cerkvam, premožnim kmetom in drugim meščanom. Koloni so bili na gospodarje vezani s kolonskimi pogodbami; zemljo so imeli v zakupu. V začetku 20. stoletja je imela skoraj vsaka briška vas kolone. Poseben primer sta bili Fojana in Barbana. Tam je grof Silverio de Baguer imel v lasti skoraj celotni vasi. Njegovo zemljo je obdelovalo kar 38 kolonskih družin. Te so s pomočjo dr. Henrika Tume leta 1922 od grofa odkupili zemljo in ustanovili prvo zadrugo v Goriških brdih: Poljedelsko društvo kolonov in malih posestnikov v Fojani. Kljub začetnim težavam, morali so kupiti orodja in odplačevati posojila, so se novi zadružniki prebijali se skozi težke čase. Tudi nenaklonjena italijanska oblast in leta pod prisilno upravo jih niso prestrašila. Zadruga je delovala do leta 1949, ko so jo ukinili. Za naslednico prve zadruge lahko imenujemo Kmetijsko delavsko zadrugo, ki je v Fojani nastala leta 1948. Njeni prvi člani so postali takratni cerkveni koloni iz Fojane, kasneje pa so se ji pridružili tudi člani prve zadruge.

Biogas production from brewery yeast in an EGSB reactor
Gregor Drago Zupančič, Milenko Roš, Miran Klemenčič, Matej Oset, Romana Marinšek-Logar, 2016, strokovni članek

Opis: Experience over a five-year period of full throughput using anaerobic co-digestion of brewery yeast for biogas production is described in this contribution. The brewery, with a total amount of available yeast (0.7 v/v %), had a 26.2 % increase in COD load and a 38.5 % increase in biogas production resulting in an increase in the biomethane/natural gas substitution ratio in the brewery from 10 % to 16 %.

Opis: Im vorliegenden Beitrag soll die fünfjährige Erfahrung mit der Co-Vergärung von Brauereihefe für die Erzeugung von Biogas im industriellen Maßstab vorgestellt werden. Der Betrieb mit den gesamten, in der Brauerei anfallenden Heferückständen (0,7 Vol.-%) brachte eine Steigerung der CSB-Fracht von 26,2 Prozent und der Biogaserzeugung von 38,5 Prozent. Infolgedessen erhöhte sich die substitutionsquote Biomethan/Erdgas in der Brauerei von 10 auf 16 Prozent.

Radioactive isotopes in ground waters of Slovenia
Katarina Kovačič, 2015, doktorska disertacija

Opis: Within the duration of three projects (J7-0363, L1-0437, L1-4280), in the period from 2008 to 2013, measurements of tritium (3H), 40K and γ-ray emitters of uranium (238U, 226Ra and 210Pb) and thorium (228Ra and 228Th) decay series in groundwaters of Slovenia were carried out. Tritium was also measured in precipitation at selected locations. Groundwater sampling sites were selected in order to cover the most representative lithological units that are found in Slovenia and were at the same time evenly distributed throughout the country. In total, 281 samples were measured from 120 different locations. Measurements in the period 2009-2013 have shown that tritium concentrations in precipitation in Ljubljana are for about 30% lower compared to those in Vienna, however they are in line with seasonal fluctuations observed in Vienna. This was an important information in the process of the reconstruction of past tritium concentrations in precipitation in Ljubljana (tritium curve) for the missing period between 1953 and 1981. Tritium curve represents the input data when determining the average age of water. In determining the influence of various parameters on the final interpretation of the groundwater age it has been found that the greatest uncertainty contribute the measurements of the tritium curve and the measurements of tritium in groundwater samples. Also, the interaction of other factors (continental effect, rainfall regime, infiltration) and the lack of knowledge of them may have a major impact on the misinterpretation of groundwater age. Based on tritium concentration, groundwaters were divided into 4 major categories, into groundwaters that are older than 100 years (tritium concentration was below the detection limit), groundwaters, where the older component prevails (concentration of tritium was between 0 and 2.5 TU), groundwaters with the age between 30 and 60 years (the concentration of tritium was on average 8 TU) and recent groundwaters with age up to 15 years (tritium concentration of about 6 TU). The natural background of γ-ray emitters was determined for each lithological unit. The most represented radionuclide was 40K with concentrations always above the detection limit. A dependency of 40K concentrations on nitrate was observed, especially in the recharge areas, where limestone prevailed. Other γ-ray emitters revealed some dependence on nitrate concentration, especially both radium isotopes (226Ra and 228Ra). The concentration of 210Pb in groundwaters is mainly due to the connection with the surface and consequently with atmospheric 210Pb. The highest concentrations of 238U and 228Ra were measured in groundwaters from recharge areas in clastic rocks with a clay component. In contrast to the expected, concentrations for all γ-ray emitters (except 210Pb) were the lowest or even not detectable, in groundwaters from recharge areas in igneous and metamorphic rocks. Among γ-ray emitters and categorization based on tritium concentrations, elevated concentrations of 238U were observed in groundwaters with prevailing older component. Elevated concentrations of 40K were also observed in them. The largest scattering of 210Pb and 40K concentrations was observed in recent waters, which indicates a connection with the surface and application of fertilizers.
Ključne besede: Groundwaters, Slovenia, tritium input curve, natural gamma-ray emitters background.
