A mineralogical-petrographical study of evaporites from Mali Kukor, Vranjkovići and Slane Stine quarry (Upper Permian evaporites from Dalmatia, Croatia)

The evaporite deposits examined in this study are located in the central part of middle Dalmatia, Croatia. In this region, Upper Permian evaporite sediments were deposited under favourable conditions onto the Variscan basement around the northern margins of Gondwana. These sediments can be subdivided into three members, a lower evaporite unit (an anhydrite member), a middle evaporite unit (a gypsum member), and an upper unit (a clastic member), and are mainly comprised of secondary gypsum that formed via the hydration of precursor anhydrite rocks. The middle evaporite unit comprises beds of gypsum as well as early diagenetic dolomites that contain gypsum sequences, extending up to 60 m maximum thickness, and overlying clastic sequences that themselves are up to 20 m thick. These Upper Permian evaporite sediments contain horizontal, irregular, gypsum lithofacies that exhibit pronounced enterolithic and boudinage structures. The characteristics of these sediments are indicative of deposition in supratidal and sabkha settings (i.e., early diagenetic dolomites and evaporites) within a shallow epicontinental marine environment with highly varied coastlines, bays, and lagoons. The secondary gypsum seen within this Upper Permian middle evaporite unit displays alabastrine and porphyroblastic secondary textures and includes corroded anhydrite relics; associated minerals include muscovite, chlorite, potassium (K)-feldspar, quartz, and amphibole. The Upper Permian evaporite sediments discussed in this study are composed of irregular, locally brecciated secondary gypsum that probably formed as a result of multiple synsedimentary collapse of pre-existing soluble mineralsand/or synsedimentary and post-sedimentary tectonics.</p

Uticaj tretiranja semena suncokreta insekticidima na posetu oprašivača i štetnih insekata

Sunflower yield is related to many factors and one of those factors is insecticide seed treatment. Aim of this research was to analyze the influence of insecticide seed treatment on pollinator and harmful insect visit, as well as on yield. Research was conducted at Rimski Šančevi, during 2008. using a commercial sunflower hybrid NS-H-111. Impact of six different insecticides was tested throughout total number of plants, number of plants damaged by insects, pollinator visit and seed yield. Among pollinators, honeybees were much more frequent than bumblebees, hoverflies and solitary bees. Harmful insects were present very rarely and leaf surface damage intensity was low, not more than 10%. Derived results show that insecticide seed treatment did not significantly influence pollinator visit. To fully understand the impact of insecticide seed treatment on pollinators, insecticide concentrations in pollen and nectar should be measured and determine the influence on pollinators.Prinos suncokreta zavisi od niza faktora, a jedan od često prisutnih je i tretman semena insekticidima. Cilj ovog istraživanja je provera uticaja tretmana semena insekticidima na posetu oprašivača i štetnih vrsta insekata, kao i njihov uticaj na prinos semena. Istraživanje je vršeno na lokalitetu Rimski Šančevi, tokom 2008. godine na hibridu suncokreta NS-H-111. Testiran je uticaj šest različitih insekticida i određivan je ukupan broj biljaka, broj biljaka oštećenih od insekata, poseta oprašivača i prinos semena. Od prisutnih oprašivača najčešće su bile pčele koje su dominirale u odnosu na bumbare, muve lebdilice i solitarne pčele. Štetni insekti su bili slabo prisutni i stepen oštećenja lisne mase nije prelazio 10%. Dobijeni rezultati upućuju na zaključak da tretmani insekticidima ne utiču značajno na posetu oprašivača. Da bi se u potpunosti sagledao uticaj insekticida na oprašivače potrebno je odrediti koncentracije insekticida u polenu i nektaru i odrediti njihov uticaj na oprašivače

Dostignuća u oplemenjivanju NS hibrida uljane repice

The increased production of oilseed rape (Brassica napus L.) is evident on a global scale, but also in Serbia in the last decade. Rapeseed is used primarily for vegetable oil and processing industry, but also as a source of protein for animal feed and green manure. Following the cultivation of varieties, breeding and cultivation of hybrid rapeseed started in the 1990's, to take advantage of heterosis in F1 generation, while protecting the breeder's rights during seed commercialization. The breeding of hybrid oilseed rape requires high quality starting material (lines with good combining abilities) for introduction of male sterility. Ogura sterility system is primarily used at the Institute of Field and Vegetable Crops, Novi Sad, Serbia. To use this system, separate lines are modified with genes for cytoplasmic male sterility (cms female line - mother line) and restoration of fertility (Rf male lines - father line). In order to maintain the sterility of the mother line it is necessary to produce a maintainer line of cytoplasmic male sterility. Creation of these lines and hybrids at the Institute of Field and Vegetable Crops was successfully monitored with intense use of cytogenetic laboratory methods. The structure and vitality of pollen, including different phases during meiosis were checked so that cms stability was confirmed during the introduction of these genes into different lines. Rapeseed breeding program in Serbia resulted in numerous varieties through collaboration of researchers engaged in breeding and genetics of this plant species. So far, in addition to 12 varieties of winter rapeseed and two varieties of spring rapeseed, a new hybrid of winter rapeseed NS Ras was registered in Serbia. NS Ras is an early-maturing hybrid characterized by high seed yield and oil content. Average yield of NS Ras for two seasons and three sites was 4256 kg ha-1 of seed and 1704 kg ha-1 of oil. Three promising winter rapeseed hybrids are in the process of registration in the Republic of Serbia and one in the EU. While addressing many challenges in breeding, especially resistance to biotic and abiotic stress, in addition to classical breeding, it is necessary to apply the cytogenetic and molecular analysis to increase the efficiency of producing competitive rapeseed genotypes.Porast proizvodnje uljane repice (Brassica napus L.) evidentan je u svetskim razmerama, a poslednje decenije i u Srbiji. Uljana repica se koristi prvenstveno za dobijanje ulja za ishranu i prerađivačku industriju, ali i kao izvor proteina za ishranu domaćih životinja i zelenišno đubrivo. Nakon gajenja sorti počelo se 90-ih godina prošlog veka sa oplemenjivanjem i gajenjem hibrida uljane repice, kako bi se iskoristio efekat heterozisa u F1 generaciji, uz istovremenu zaštitu prava oplemenjivača prilikom prometa semena. U oplemenjivanju hibrida uljane repice neophodno je u kvalitetan početni materijal (linije dobrih kombinacionih sposobnosti) uneti svojstvo muške sterilnosti. U Institutu za ratarstvo i povrtarstvo, Novi Sad koristi se prvenstveno Ogura sistem sterilnosti. Korišćenje ovog sistema obuhvata unošenje citoplazmatske muške sterilnosti (cms linije majke) i gena za restauraciju fertilnosti (Rf linije oca). Da bi se sterilnost linije majke održala neophodno je proizvesti i liniju održivača citoplazmatske muške sterilnosti. Prilikom stvaranja ovih linija, hibrida i u semenskoj proizvodnji u Institutu za ratarstvo i povrtarstvo intenzivno i vrlo uspešno su korišćene citogenetske laboratorijske metode. Analizirana je građa i vitalnost polena, kao i različite faze tokom mejoze i utvrđena stabilnost svojstava prilikom unošenja ovih gena u različite linije. U oplemenjivanju uljane repice u Srbiji postignuti su značajni rezultati kroz saradnju istraživača koji se bave genetikom i oplemenjivanjem ove biljne vrste. Do sada je pored 12 sorti ozime i dve sorte jare repice u Srbiji registrovan hibrid ozime uljane repice NS Ras. NS Ras je ranostasni hibrid koji se odlikuje visokim prinosom zrna i ulja. Prosečan prinos u dve sezone za tri lokaliteta je bio 4256 kg ha-1 semena i 1704 kg ha-1 ulja. Još tri perspektivna ozima hibrida uljane repice nalaze se u postupku registracije u republici Srbiji i jedan u EU. U rešavanju mnogih izazova u oplemenjivanju, prvenstveno otpornosti na biotski i abiotski stres, pored klasičnog oplemenjivanja neophodno je primeniti, citogenetske i molekularne analize za povećanje efikasnosti oplemenjivanja uljane repice

CANCER PATIENTS FOLLOW-UP – CROATIAN SOCIETY OF MEDICAL ONCOLOGY CLINICAL GUIDELINES Part II: renal cell cancer, urinary bladder cancer, prostate cancer, testicular cancer

Liječenje onkoloških bolesnika mora se temeljiti na multidisciplinarnom pristupu, a provodi se u specijaliziranim onkološkim centrima. Nakon završetka specifičnog onkološkog liječenja daljnje praćenje uglavnom provode onkolozi, ali je uloga liječnika primarne zdravstvene zaštite (PZZ) sve važnija i potrebno ju je jasno definirati. Trenutačno se većina preporuka za praćenje ne temelji na prospektivnim studijama, već se zasniva na stručnim mišljenjima pojedinih onkoloških centara ili specijalista. Hrvatsko društvo za internističku onkologiju (HDIO) ovim preporukama želi standardizirati i racionalizirati dijagnostičke postupke u praćenju onkoloških bolesnika nakon završetka primarnog liječenja, u bolesnika s ­rakom bubrega, rakom mokraćnog mjehura, rakom prostate i rakom testisa.The treatment of oncological patients must be based upon multidisciplinary approach, and takes place in specialized oncological centers. By the end of a specific oncological treatment further follow-up is being managed mostly by the oncologists, but the role of the general practitioners becomes more important every day and therefore should be precisely defined. Nowadays, most of the existing follow-up guidelines are not based on prospective studies, but on the experts opinion of individual oncological centers or specialists. The aim of the Croatian Society of Medical Oncology (CSMO) with these recommendations is to standardize and rationalize the diagnostic procedures algorithm in the follow–up of ­oncological patients after primary treatment, in patients with renal cell cancer, urinary bladder cancer, prostate cancer and testicular cancer

Cancer is the second most important cause of death in our country, immediately after cardiovascular diseases. With the assumption that cancer incidence and mortality will increase in the next years, projections show that the costs of diagnosis and treatment of cancer will be significantly increased, both due to the introduction of new diagnostic techniques and innovative medicines and treatment methods. Consequently, the imperative of making optimal use of financial resources, available personnel and techniques is all the more necessary in or-der to ensure the continuity of adequate diagnosis and treatment. Optimal use of diagnostic methods can pre-vent unnecessary processing delay, waste of financial resources and unnecessary burden on healthcare work-ers, and shorten waiting lists. HDIO has made these guidelines with the aim of overcoming these problems, rationalizing and standardizing diagnostic procedures in everyday clinical practice. Guidelines should help us to select, from the entire range of diagnostic procedures available, those which are most relevant to a particular localization and clinical extension of the disease

GeoERA Raw Materials Monograph : the past and the future

ABSTRACT: GeoERA Minerals projects have produced data aimed at supporting Europe’s minerals sector and to assist the European Commission to realise its goals for raw materials. Data has been compiled on mineral occurrences and mineral provinces across Europe, in particular, areas with potential to host Critical Raw Materials. Anecdotal evidence from the minerals sector provides an indication of the likelihood of exploration leading to mine development. For every 1,000 mineral showings examined, only 100 may receive further exploration work and of those 100, only 10 may warrant more detailed sampling either through trenching, drilling or other means and of those 10 only 1 may proceed to an evaluation through a full feasibility study which itself has only 50% chance of being positive. Following this, any project for which a mine proposal is made must undergo a full evaluation and permitting by authorities including full public consultation. The proposal may or may not pass this scrutiny. In terms of a schedule, the generally accepted minimum time frame from discovery to production is 10 years and usually much more, up to 20 years.info:eu-repo/semantics/publishedVersio

GEOCHEMICAL AND MINERALOGICAL CHARACTERISTICS OF UPPER PERMIAN EVAPORITE SEDIMENTS FROM CENTRAL DALMATIA

Pojave i naslage evaporita te njihovih pratećih naslaga u središnjoj Dalmaciji razvijene su na većem broju lokaliteta. Evaporitne naslage u kontinentalnom dijelu središnje Dalmacije su izdvojene kao jedinstvena cjelina gornjopermske starosti. Sedimenti se sastoje od evaporitih, karbonatnih i klastičnih naslaga te su uglavnom sastoje od sekundarnog gipsa koji je formiran hidratacijom anhidritnih stijena. Sedimentološka opažanja, u kombinaciji s rezultatima mineraloških i geokemijskih istraživanja, obuhvatila su gornjopermske evaporitne u ležištima gipsa Mali Kukor, Vranjkovići i Slane Stine i klastične sedimente u njihovim obližnjim lokalitetima u središnjem dijelu Dalmacije. Geokemijskim istraživanjima utvrđene su karakteristike proučavanih evaporitnih sedimenata, dopuštajući tako pobližu rekonstrukciju uvjeta taloženja, trošenja, reckliranja te tektonskih okoliša i provenijencija. Na istraživanim ležištima gipsa, a na osnovu sedimentoloških promatranja, utvrđeni su litofacijesi evaporitnih sedimenta: evaporitni sedimenti s horizontalnom laminacijom, evaporitni sedimenti s valovitom i nepravilnom laminacijom, gipsno-dolomitne breče, masivni sekundarni gips te budine (boudinage) strukture. Mikroskopska istraživanja ukazuju da većina gipsnih mikrofacijesa gornjopermskih evaporita predstavljaju rezultat hidratacije iz ishodišnog anhidrita. Na ležištima gipsa najčešće su zabilježena dva tipa mikrofacijesa. Jedan tip je alabasterski do granoblastični sekundarni gips, dok je drugi tip porfiroblastično sekundarni gips. Gornjopermski platformski evaporitni sedimenti talože se u epikontinentalnim morima u velikim područjima kontinenta prekrivenog morskom vodom. Evaporitni i karbonatni sedimenti se talože na muljnim ravnicama u okolišima koji se prostiru na nekoliko stotina kvadratnih kilometara.The occurrences and deposits of evaporites and their accompanying deposits in central Dalmatia have been developed on a number of localities. The evaporate deposits in the continental part of middle Dalmatia are separated as Upper Permian evaporite sediments. Sediments consists of evaporite, carbonate and clastic deposits. Sedimentological observations, combined with the results of mineralogical and geochemical studies, included Upper Permian evaporite in the Mali Kukor, Vranjkovići and Slane Stine deposits and clastic sediments in their nearby locations in the central part of Dalmatia. Geochemical studies have determined the characteristics of the studied evaporite sediments, allowing more closely the reconstruction of precipitation, weathering, recycling and tectonic environments and provenances. In the investigated deposits of gypsum, and on the basis of sedimentological observations, litofacies of evaporite sediments were identified: evaporite sediments with horizontal lamination, evaporite sediments with wavy and irregular lamination, gypsum-dolomite breccia, massive secondary gypsum and boudinage structure. Microscopic studies indicate that most of the gypsum microfacies of Upper Permian evaporites are the result of hydration via the hydration of precursor anhydrite rocks. Two types of microfacies are most commonly found on gypsum deposits. One type is alabastrine to granoblastic secondary gypsum, while another type is porphyroblastic secondary gypsum. Upper Permian platform evaporite sediments collapse in epicontinental seas in large continents covered with sea water. Evaporite and carbonate sediments are deposited on salient plains in environments extending over several hundred square kilometers
