Reagiranje flue-cured duhana na dubinu oranja i gnojidbu dušikom istraživano je u stacioniranom poljskom pokusu u Žankovcu (Vinkovci) na eutr9ično smeđem tlu od 1983-1985. godine. Dubina oranja povećala je prinos duhana u prosjeku za 15, 98 do 16, 98 % i prosječnu cijenu za 10, 59 %. Gnojidba dušikom je povećala prinos za duhana za 6, 53 do 11, 64 % i sadržaj nikotina za 6, 16 - 24, 7 %. Istovremeno je primjenom dušika i ishrani flue-cured duhana sadržaj reducirajućih šećera opao za 20, 01 - 42, 07 % i prosjećna cijena za 3, 66 - 14, 64 %. Nadalje, autori ističu da je zbog povećane zbijenosti podoraničnog sloja istraživano tlo potrebno dublje orati a u gnojidbi flue-cured duhana primijeniti maksimalno 20 kg/ha dušika.

Tests to use metallized pellets of pyrite residue were carried out in a 40-(metric)-tonne electric-arc furnace of 12,000-kVA power.The pellets were added in quantities of 15 to 45 per cent of the total charge, which was loaded with baskets.It can be stated that, despite the lesser degree of metallization and the lower FeMet content in the metallized pellets of pyrite residue, the production of the steel proceeded without any difficulties, conversion and carbon boil were normal, and the yield of the steel produced was satisfactory.The mechanical properties (strength, ductility, expansion. contraction) of these steels made from pellets were found to be the same as or superior to those of steels made from scrap alone. Resume Des essais utilisant des boulettes metallisees de residus de pyrites ont ete realises dans un four a arc electrique de 40 tonnes (metriques) et d'une puissance de 12000 kva.Les boulettes ont ete ajouees dans des proportions allant de 15 a 45 pour cent de la charge totale, cette ...

We treated 60 patients with cisplatin-based combination chemotherapy before definitive surgery and/or radiation. All had squamous cell tumors of the head and neck, stages II to IV, M0. Twelve patients (20%) achieved a complete remission after chemotherapy. Eight of these patients showed no histologic evidence of residual disease after biopsy or surgery. Definitive local therapy with surgery and/or radiation was carried out on almost all patients regardless of the extent of the response to preceding chemotherapy. Chemotherapy-induced complete responders have had an improved survival rate in comparison with patients achieving a partial response or less. The extent of primary tumor correlates inversely with a complete response to chemotherapy.

We are comparing - through both online and offline observations - peculiarities and common features among a web students’ community and pro public water citizen’s movements in Bologna. Observing the students’ activity in a Laboratory on 2.0 territorial marketing we inferred that the communities who lives and discuss in the medium are, in turn, influenced by it. The pro public water movements rose up recently to promote their instances during a referendum, however after their obtained a great success in terms of participation and final result, the sense of belonging weakened quickly. These observations are common to both cases and let us suppose that individuals may identify with more than one community contemporaneously, as well as serially, changing affiliations with great fluidity. The second common feature we highlighted is the need that catalyzes the interest in becoming part of an online community. Both the students and people participating to online and offline forum where interested in obtaining, sharing or producing information lacking in mainstream media. In this research paper we describe laboratory’s and water movements’ participants' acquisition of new skills and expertise, as well as the practices that emerged in their communities. We suppose a shift from the classical two-steps-communication flow to a form of scattered clouding steps flow of communication where opinion leaders at the same time are spread in the network and they can quit or be dismissed from this role quickly, possibly unregretfully.

Die Untersuchung der Kinetik der Alkaliverflüchtigung aus Primär- und Sekundärhochofenschlacken unterschiedlicher chemischer Zusammensetzung unter definierten Laborbedingungen und die Bestimmung der Alkalioxidaktivität von Hochofenschlacken ist Gegenstand der vorliegenden Arbeit. Bei den kinetischen Untersuchungen waren der Einfluss der Temperatur und der chemischen Zusammensetzung der Schlacke (CaO/SiO2, Al2O3, MgO) sowie der Einfluss der Gasatmosphäre, der Schwefel- und Graphitzugaben von Interesse. Außerdem wurden die primären Hochofenschlacken untersucht. Für die primären Laborschlacken wurde in dieser Arbeit außer Temperatur und Basizität auch der FeO-Gehalt als Einflussgröße betrachtet. Im thermodynamischen Teil der Arbeit wurde eine Methode zur Bestimmung der Alkalioxidaktivität in den flüssigen Schlacken, insbesondere den Hochofenschlacken, entwickelt und optimiert. Die Na2O-Aktivität der Zwei- und Dreistoffschlacken wurde gemessen. Das Schlackenmodell nach Gaye zur Bestimmung der Alkalioxidaktivität wurde erfolgreich getestet und kann zur Voraussage des Einflusses auf den Alkaliaustrag mit der Hochofenschlacke angewendet werden. Mit den Ergebnissen dieser Arbeit können quantitative Maßnahmen zur Verbesserung des Alkaliaustrags über die Abstichschlacken des Hochofenbetriebes eingeleitet werden.

Nakana teksta je promotriti djelić srednjovjekovlja grada Ptuja. Na temelju analize dijela njegova inventara sadržana u velikom groblju na redove, koji se prostire na zapadnoj zaravni Grada, na tzv. Turnirskom trgu, nastojimo prikupiti elemente za proučavanje vremena nastanka i trajanja posjedanja jednog dijela ovog ukopišta.
