Začetki načrtnega zbiranja trav in metuljnic segajo v 50 leta prejšnjega stoletja, ko so iz zbranega materiala kasneje požlahtnili prve slovenske sorte trav in metuljnic. V prispevku je poleg ...zgodovine prikazano sedanje delo genske banke krmnih rastlin in nekateri rezultati vrednotenja genskih virov v zadnjem desetletju. Za najprimernejši način zbiranja genskih virov so se pokazale večdnevne odprave, katerih cilj so lahko travniki ali kmetije, ki še pridelujejo lokalne populacije oziroma stare sorte kmetijskih rastlin. Trenutno v genski banki hranimo 761 vzorcev krmnih rastlin, od tega je 281 metuljnic, 352 trav, 73 travniških zeli in 55 krmnih poljščin. Večina krmnih rastlin je tujeprašnih, kar otežuje množenje vzorcev zaradi potrebe po prostorski izolaciji. Obnova starih vzorcev je in bo v prihodnje velik izziv tudi naše genske banke. Pri ocenjevanjih travniškega mačjega repa (Phleum pratense), navadne pasje trave (Dactylis glomerata L.), plazeče detelje (Trifolium repens L.), navadne nokote (Lotus corniculatus L.) in navadne turške detelje (Onobrychis viciifolia Scop.) smo med posameznimi ekotipi ugotovili dokaj veliko morfološko raznolikost. Ekotipi se med seboj razlikujejo tudi po kemijski sestavi, krmni vrednosti in drugih agronomskih lastnostih.

Authoring a collaborative, interactive Mixed Reality (MR) tour requires flexible design and development of various software modules for tasks such as managing geographically distributed participants, ...adaptable travel and virtual camera techniques, data logging for assessment of the incorporated techniques, as well as for evaluating the Quality of Experiences (QoE). In most cases, authors might have to develop all these software modules, instead of focusing only on the virtual environment design. In this article, we propose SCeVE, a component-based framework that supports flexible design and authoring of interactive MR tours by offering ease of access to four major design choices: (i) S ynchronization, (ii) C ollaborative e xploration, (iii) V isualization, and (iv) E valuation. Based on tour requirements, an author can access one or more components (or software libraries) of design choices via SCeVE’s API (Application Programming Interface) services , as demonstrated by the two case studies on group travel in a plant walk MR tour. SCeVE framework is innovative in the sense that it facilitates group travel in virtual environments involving “live” models of participants from geographically distributed sites. SCeVE empowers authors to focus only on the design of the required virtual environments. They can quickly build a diverse set of collaborative MR tours by utilizing the flexibility of SCeVE in terms of the various available options for traveling, rendering on multiple devices, and virtual camera viewpoint computation strategies. By providing data logs of various components, SCeVE facilitates performance evaluation of the various strategies used as well as the user experience in collaborative MR tours. SCeVE is designed in an extensible manner, allowing authors to add devices and software services as additional components.
Od svibnja do listopada 2011. godine na području sjevernoistočne Slovenije (Rakičan, 46°65‘21‘‘ s.g.š., 16°19‘13‘‘ v.g.d., 188 m n.v.) izveli smo pokus u kojem smo istraživali značajke tri vrste ...trava i četiri mješavine trava na srednje intenzivno uzgojenom travnjaku poslije dvije godine rasta. Pokus je bio postavljen u rujnu 2009. godine po metodi slučajnog redosljeda pokusnih jedinica u četiri ponavljanja. Veličina osnovne pokusne jedinice bila je 10 m2. Količina sjemena za sjetvu bila je 250 kg na hektar. Pokus smo gnojili s 200 kg N na ha (u 7 prihrana), 60 kg P2O5 na ha i 120 kg K2O na ha. U pokusu smo ocjenjivali i određivali: boju travnjaka, brzinu rasta, prazna mjesta, gustoću trave, zakorovljenost, otpornost na sušu, otpornost na bolesti, utjacaj vremenskih uvjeta i prinos suhe tvari na ha pojedine mješavine. Analiza rezultata pokusa je pokazala da se mješavina trava 3, sastavljena od trstikaste vlasulje(Festuca arundinacea) – sorta ‚Arid 3‘ (50 %) i dvije sorte engleskog ljulja (Lolium perenne L.) – sorte ‚Panderosa‘ (25 %) i sorte ‚Mondial‘ (25 %) značajno isticala, po ocijenjenim parametrima od ostalih vrsta trava i mješavina trava iz pokusa
From May to October 2011, a field experiment was conducted in the north eastern Slovenia (Rakičan, 46°65’21’’ N, 16°19’13’’ E, 188 m s.l.), where we studied the properties of three grasses and four grass mixtures appropriate to create a medium- intensive ornamental lawn after the second year of growth. The experiment was designed in September 2009 as randomized blocks with four repetitions. The size of the basic plot was 10 square metres. For sowing 250 kg of seeds per hectare were used. The treatments were fertilized with 200 kg N ha -1 (in seven fertilizations), 60 kg P2O5 ha -1 and 120 kg K2O ha -1.In the experiment, we assessed and evaluated turf colour, growth rate, bare spots, turf density, weeds, drought resistance, and turf resistance to disease, the impact of weather conditions and dry matter yield of each mixture. The results obtained in the experiment indicated that the grass mixture No. 3, composed of tall fescue (Festuca arundinacea) – cv. ‘Arid 3 (50%) and perennial ryegrass (Lolium perenne L.) – cv. ‘Panderosa’ (25%) and cv. Mondial’ (25%), significantly differed from the remaining grasses and grass mixtures according to the observed parameters.
Integrated data of calcareous plankton and benthic foraminifers from the pre-evaporitic interval of Trave section (Central Italy) allowed the reconstruction of surface and bottom-water conditions in ...the Central Mediterranean during the interval from 7.61 to 6.33
Ma, preceding the Messinian Salinity Crisis.
Our data point out a three-step paleoenvironmental evolution. During the first stage (7.61–7.02
Ma) benthic foraminiferal assemblages depict stable, well-oxygenated and ventilated bottom-water conditions, while the surface water records variable temperature and high nutrient conditions, probably associated with strong seasonality. The second stage (7.02–6.70
Ma) points to unfavourable bottom-water condition, triggered by deep-sea stagnation. This is witnessed by a significant decrease in oxygen concentration and biotic diversity, and by the presence of stress-tolerant taxa. A general warming of the surface water and a strongly stratified water column, characterized by an expanded mixed layer, are also recorded.
From 6.70
Ma onwards (third stage), a prominent change to more restricted, low-oxygenated, hypersaline conditions at the sea floor is testified by the total disappearance of deep-dwelling planktonic foraminifers and the increasing abundance of stress-tolerant species. Calcareous plankton reflects high instability of the surface water in terms of nutrients, temperature and salinity. During this stage the environmental deterioration reaches intermediate depths in the water column.
The initial change toward a step-wise isolation of the Central Mediterranean bottom-waters is probably related to a general warming, responsible for a first slowing-down of the vertical circulation, favouring stratification of surface and intermediate waters and stagnation of bottom-waters. This warming is related to the restricted connection between the Mediterranean Sea and the Atlantic Ocean, which occurred since 7.146
Ma.
In the Trave section, the isolation of bottom-waters most likely occurred at the same time as in other Mediterranean sections. However, due to the presence of a hiatus it cannot be excluded that it occurred with a delay of ~
100
kyr, probably related to the shallower paleodepth of the basin.
The bright example of John the Baptist Lalangue proves that Croatia has been an integral part of Europe for centuries. A dynamic exchange of people and ideas has taken place ever since Croats were ...baptised. The paper deals with one such foreigner from Western Europe who not only healed sick people, but through his writings also strived to increase the level of enlightenment among common people. His pharmacopeia is very simple even from the perspective of the then medical science. It comprises medicinal plants and other medicinal substances that are easily available to everyone. This paper highlights the original description of certain medicinal herbs and is written in today’s language in order to facilitate the reading. The paper also contains an appendix listing the most important dictionaries and recipes by our older authors. The proportion of included pharmacopeia indicates the extent to which people living in a certain period of time were familiar with plants and their healing properties. Even though Lalangue wrote his enlightenment booklets, translated by Croatian Franciscans, originally in Latin, he nevertheless gained the honourable title of the father of Croatian medical literature.
Based on the great classic, Best Dives of the Caribbean, this publication zeroes in on the best dives of Belize. Includes the latest and best dive and snorkel sites, each rated for visual excellence ...and marine life. The author's knowledge of the Caribbean sites is unparalleled. From sunken planes and snorkel trails to blue holes, the best destinations beneath the waves are covered. Also covered are the best places to stay & eat, activities, sightseeing and all practical details needed for visitors. "I have bought both editions of this book, mostly because the first edition got so dog-eared that I wanted a clean one for vacation last year. The book is a marvelous source of information for both the snorkeler and the diver. The authors divide the book into chapters on individual islands, starting out with a brief but interesting history of the island, a topographical description, relative location map, best time to go, weather, and proximity to other islands. They then rate the island's diving locations, awarding from 1 to 5 stars, and provide another larger map visually locating the sites. Each site is described in detail, with info on depth, sea life, currents, visibility, photo ops and difficulty level. As if that weren't enough, they include some (but not enough!) beautiful photos, and end each chapter with yet more info on dive operators (detailed), beaches, other activities, dining, accommodations (with rates, addresses and phone numbers), medical facilities, documentation requirements, currency, driving, local customs, departure taxes, etc. I've been exploring the Caribbean for almost a decade now; I take this compact book with me everywhere. My only complaint: I wish they covered more islands!" -- (Suziekew) "The new, 2006, third edition of Best Dives of the Caribbean is packed full of dive-vacation planning information. It tells what time
of year to go, the most popular dive sites with details on what to expect, depths, average sea conditions-- I get seasick if it's rough and prefer diving where the sites are ten minutes or less by boat, or better yet accessible from the beach. Indeed, some of the other one-desination guides are more suitable for the coffee table, but they don't tell me anything about the dive resorts, the cost. I would not consider planning a dive-vacation to the Caribbean without consulting this gem of a travel guide. The dive resort write ups are detailed and give rates and package deals. Any, the author gives an email for additional questions." -- Janice Brink Diver-friendly resorts and hotels are featured, along with many recommended outfitters for learning, improving and mastering your diving skills. A list of decompression chambers is given. Landlubbers will appreciate the sightseeing sections. Color photos enhance the text. Maps show dive site locations. A must-have for divers, snorkelers, or those who just love to float in liquid turquoise. -- Brenda Fine, Travel Editor, NY Law Journal Don't plan a dive without it! Concise and informative... one of the few bargains of the decade. -- Wendy Canning Church, Divers Exchange International It's super! A great reference and we love it. -- Dive Travel Magazine The bible of Caribbean dive-travel. I highly recommend it. -- Chris Lofting, The Travel Show, WOR Network Radio When I'm thinking about where to go diving next, I always thumb through this gem... It's a trustworthy publication. -- In Depth/Undercurrent Magazine "I thought this was one of the best books for the travelling diver that I have ever read. A recent trip to Aruba proved it. Recommendations are still right on the mark." -- C. Harmon.
