391. Innovative technology for cyanobacterial bloom control : LIFE Stop CyanoBloomMaja Zupančič Justin, Marko Gerl, Gorazd Lakovič, Bojan Sedmak, Tinkara Rozina, Neža Finžgar, Maja Čič, Mario Marinovič, Luka Teslić, Jošt Grum, Maša Čater, Tina Eleršek, Andrej Meglič, Andrey Yakuntsov, Lovro Pokorn, Tomaž Kralj, Matjaž Berčon, Branko Hamiti, 2017, final research report Abstract: Despite the efforts invested into measures to prevent water eutrophication, like prevention and treatment of point and dispersed discharges, the eutrophication still occurs. One of the unwanted consequences of eutrophic water state is the occurrence of excessive cyanobacterial blooms. Mass occurrence of cyanobacteria is a significant health risk related to surface waters in EU and worldwide since most of the cyanobacterial genera produce cyanotoxins. Besides toxicity, cyanobacterial blooms cause an increase in the turbidity of water and create taste and odour problems. All mentioned represents substantial economic losses in sectors like aquaculture, tourism, drinking water facilities and indirect losses due to increased healthcare expenditures and environmental degradation. It is, therefore, necessary to find appropriate solutions for rapid detection and also in-lake prevention of bloom occurrence despite, for example, existing high eutrophic conditions in the water body. The proposed project represents such a solution.
In the frame of the LIFE Stop CyanoBloom project, we have designed two solar powered robotic vessels for the in-lake detection and control of cyanobacterial proliferation. Each vessel is capable of three-dimensional localisation of cyanobacteria by measuring fluorescence of pigments involved in the process of photosynthesis. The vessels are additionally equipped with electrochemical cells using boron doped diamond electrodes fixed on board, producing short-lived hydroxyl radicals, which prevent cyanobacterial proliferation as well as cyanotoxins inactivation. Hydroxyl radicals cause different levels of damages to cyanobacterial cells as well as stress, that may also result in phage induced cyanobacterial lysis. Natural control of cyanobacterial density by lytic cyanophages is known for several years. The mixing of water during the electrolytic cell operation also increases the potential contacts of cyanobacteria with cyanophages, disturbs cyanobacterial buoyancy and generates additional nutrients for nontoxic phytoplankton population. Additional newly developed equipment of the vessel allows advanced automated navigation (automatic docking, avoiding obstacles, maintaining the position in windy conditions, etc.), sampling from different depths, real-time data transfer, statistical analysis and graphical presentation using the adequate software.

393. Detection, Interpretation and Reporting on the presence of authorised and unauthorised genetically modified materialsIlaria Ciabatti, Jana Žel, 2017, final research report Abstract: Genetically modified organisms (GMOs) and products derived thereof have been commercialised on the food and feed market for more than twenty years. Many countries in the world have introduced legislative requirements for the authorization, traceability and labelling of GMOs, but the regulatory framework may differ from country to country. Various factors, including commercial interests, drive the request of developing companies for the authorisation and marketing of GMOs in specific areas of the world. This leads to the situation where a certain GM event may have different authorisation statuses in different countries (what is sometimes referred to as “asynchronous GMO approval”).

394. On G-Drazin partial order in ringsGregor Dolinar, Bojan Kuzma, Janko Marovt, Dijana Mosić, 2024, original scientific article Abstract: We extend the concept of a G-Drazin inverse from the set $M_n$ of all $n \times n$ complex matrices to the set ${\cal R}^D$ of all Drazin invertible elements in a ring ${\cal R}$ with identity. We also generalize a partial order induced by G-Drazin inverses from $M_n$ to the set of all regular elements in ${\cal R}^D$, study its properties, compare it to known partial orders, and generalize some known results.
Keywords: Drazin inverse, core-nilpotent decomposition, partial order, annihilator, ring

396. Terensko kartiranje morskih habitatnih tipov Natura 2000 v slovenskem morju : končno poročiloLovrenc Lipej, Borut Mavrič, Milijan Šiško, Domen Trkov, Martina Orlando-Bonaca, 2018, final research report Abstract: Namen javnega naročila “Kartiranje morskih habitatnih tipov Natura 2000 v slovenskem morju” je pridobivanje kakovostnih podatkov o habitatnih tipih v sklopu Natura 2000 v slovenskem delu Jadranskega morja. V okviru naloge je bilo zastavljeno kartiranje habitatnih tipov HT 1110 (peščeno in detritno dno pravega obalnega pasu – sandbanks slightly covered with water all the time), HT 1120 (podmorski travnik s pozejdonko – Posidonia beds) in HT 1170 (morski grebeni - reefs) na 4 območjih in sicer pred rtom Ronek in pred Debelim rtičem, na predelu peščin na Debelem rtiču, na območju med Žusterno in Izolo ter na predelu med Strunjanom in Fieso. Ti podatki bodo uporabni za poročanje v skladu z Direktivo 92/43 EGS o habitatih. Za dosego tega cilja smo izbrali standardne in uveljavljene metode, ki smo jih kombinirali z modernimi tehnikami.
V faznem poročilu smo poročali o obsegu opravljenega kartiranja in preliminarnih rezultatih ter navedli osnutek metodologije za kartiranje morskih habitatov in habitatnih tipov. V tem poročilu pa poročamo o končnih rezultatih kartiranja habitatnih tipov, navajamo predloge za izbor deskriptorjev in vzorčevalnih metod ter podajamo nekatera priporočila za učinkovito spremljanje stanja.

397. Sodobna dognanja : 8. šola o ginekološkem raku2024, not set Abstract: Raki rodil predstavljajo pomemben zdravstveni izziv za ženske po vsem svetu. So raznovrstna skupina bolezni katere preživetje se močno razlikuje glede na prizadetost organa, razširjenost
bolezni, odgovora na zdravljenje in psihofizičnega stanja bolnice.
V zadnjih letih smo priča izjemnim napredkom na področju medicinske obravnave in zdravstvenih raziskav, ki so privedla do bistvenih izboljšav pri obravnavi bolnic z ginekološkim rakom. Sodobne metode zdravljenja ne le povečujejo možnosti za preživetje, temveč bistveno prispevajo k višji kakovosti življenja onkoloških bolnic. Z vlaganjem v raziskave in izobraževanje lahko dosežemo nove preboje, ki bodo koristili prihodnjim generacijam žensk.

399. Varstvo hrošča puščavnika v Krajinskem parku Tivoli, Rožnik in Šišenski hrib : monitoring puščavnika (Osmoderma eremita) v letih 2018 in 2019Al Vrezec, Špela Ambrožič Ergaver, Andrej Kapla, 2019, final research report Abstract: V letih 2018 in 2019, smo spremljali učinek naravovarstvenega ukrepa za puščavnika, na območju saniranih dreves v mestnem parku Tivoli. Izvedli smo tudi prvo in drugo ponovitev razširjenega monitoringa puščavnika na celotnem območju Krajinskega parka Tivoli, Rožnik in Šišenski hrib. V letu 2018 smo potrdili en osebek puščavnika, na območju saniranih dreves v mestnem parku Tivoli, prav tako v letu 2019. Iz pridobljenih rezultatov je razvidno, da je bil v letih 2018 in 2019 populacijski minimum. V sklopu razširjenega monitoringa puščavnika, na celotnem območju krajinskega parka, smo vrsto v letu 2018 potrdili na eni lokaciji na območju Šišenskega hriba. Na območju Krajinskega parka Tivoli, Rožnik in Šišenski hrib je to prva najdba puščavnika izven mestnega parka Tivoli.

400. Strokovna izhodišča za oblikovanje varstvenih ukrepov za visokogorska jezera v Triglavskem narodnem parku : zaključno poročiloAnton Brancelj, final research report Abstract: V letu 2019 je bilo opravljeno ponovno fotografiranje jezer iz zraka v Triglavskem narodnem parku. Zadnje je bilo narejeno l. 2011, v približno istem obdobju (sredina oktobra).
Na podlagi posnetkov iz zraka in predhodnih analiz na terenu je bila opravljena analiza sedanjega ekološkega stanja jezer ter predlagane smernice za upravljanje v naslednjem upravljalskem obdobju (2020-2025).
Jezera nad gozdno mejo so v dobrem ekološkem stanju, vendar so se v večini od njih pojavili makrofiti (lasastolista vodna zlatica) in tudi nitaste zelene alge. Človeški dejavnik za spremembe je malo verjeten. Glavni vzrok je višanje povprečnih letnih temperatur, s tem krajše obdobje ledu in taljenje pemafrosta pod gruščem in tudi v jamah. Stanje jezer je kljub temu označeno kot zelo dobro ekološko stanje.
Tri jezera, ki v katera so bile v preteklosti naseljene ribe (Krnsko jezero, Dupeljsko jezero in Črno jezero) ne kažejo večjih sprememb in se jih lahko uvrsti v jezera s dobrim ekološkim stanjem.
V slabem ali zelo slabem ekološkem stanju je Dvojno jezero in Jezero na Planini pri jezeru. Na obeh jezerih so predvideni omilitveni ukrepi (izboljšanje delovanja MKČN in izlov rib), ki pa po ocenah ne bodo prinesli kratkoročnih učinkov. Lahko pa omilijo oz. upočasnijo slabšanje stanja jezer.
