Na podstawie analogii struktur budowli podziemnych – warszawskiego Elizeum i wielu obiektów fortecznych z XVIII-XIX w., artykuł podejmuje próbę zestawienia historycznych metod zabezpieczania ich ...wnętrz przed wilgocią przenikającą z nasypów, kondensacyjną, podciąganą kapilarnie lub dyfundującą z gruntu. Sposoby zabezpieczania przeciwwilgociowego w fortyfikacji nowożytnej zostały wypracowane w ciągu 4 wieków jej rozwoju (XVI-XIX), w wyniku stopniowego gromadzenia doświadczeń i wiedzy inżynierskiej. Ważnymi elementami tych zabezpieczeń były okładziny z gliny/iłu oraz korytarze obiegające pomieszczenia podziemne o funkcji nie tylko komunikacyjnej, ale również otuliny izolacyjno-wentylacyjnej. Budowle podziemne, poprawnie zaprojektowane na skrajnie niekorzystne warunki użytkowania, mogą trwać dzięki delikatnej równowadze, którą bardzo łatwo naruszyć. Pierwszym warunkiem równowagi jest utrzymanie właściwego reżimu wentylacji i ogrzewania wnętrz podatnych na kondensację. Na zakończenie zaproponowano działania pielęgnacyjno-eksploatacyjne mające na celu zahamowanie postępującej degradacji obiektu oraz zakreślono wskazania do programu badań i założeń przedprojektowych do przyszłych, niezbędnych prac remontowych i konserwatorskich.
V prispevku so zajete naravnogeografske značilnosti Rakovško-Unškega polja, ki leži v Notranjskem podolju. Poleg geoloških in reliefnih značilnosti so obravnavane tudi druge naravne sestavine te ...pokrajinske enote. Večji poudarek je posvečen vodnim in podnebnim razmeram ter prstem. Večletna zbiranja podatkov so pokazala, da Rakovško-Unško polje ni suho polje, saj po večji količini padavin izvira voda v več izvirih, teče po polju in ponika v ponikalnicah. Merjenja zračnih temperatur v mirnem zimskem anticiklonalnem vremenu so pokazala, da tudi na tem polju nastopa temperaturni obrat. Za prsti je značilno, da so s pedogenezo na robnih delih polja nastale na dolomitni kamnini, na dnu polja pa po vsej verjetnosti na glinasti matični podlagi. Na samem dnu polja naravne vegetacije ni več, razprostira se antropogena raba in z njo povezano rastlinstvo. Robne dele polja poraščajo travišča in gozd bora s trirobo košeničico.
In this paper, a preliminary analysis of the landslide inventory is presented for the wider area of the municipalities of Glina and Dvor, within Sisak-Moslavina County in Croatia, where LiDAR ...scanning for 45.85 km2 was conducted. Landslide polygons were outlined based on the visual interpretation of HRDEM derivates. In total, 477 landslides were contoured with an average landslide density of 9.85 per km2. Most of the landslides are characterised as moderate, shallow, and not recent. The spatial relationship between landslides and geological units is expressed with the landslide index. Subsequently, the geological units were grouped into four engineering geological units representing different susceptibilities to landslides. The geological units most prone to landslides are the Eocene, Oligocene, Palaeocene and Jurassic sandstones. Even though all geological units were analysed here, the majority of landslides are within sandstones. A particular emphasis was on landslide occurrence in metamorphic and igneous rocks of the ophiolite sequence, a distinctive characteristic of the research area where less susceptibility to landslide processes was observed. Moreover, to further distinguish the differences between the units in the area a morphometric characteristic (relief) and drainage network was also analysed. The purpose of this analysis was to additionally confirm the landslide susceptibility assessment and the division of geological units into engineering geological units, which again implied the different behaviours between landslides in igneous and metamorphic rocks compared to sandstones. Because the research area is poorly studied regarding landslide susceptibility, relief, and drainage networks, these findings will be a step forward in recognising the relationship between them and creating a base for the development of a landslide susceptibility map for this area.
The Glina-type flanged axes were acknowledged as such in 1975 by Alexandru Vulpe. Seventeen artefacts of this type exist up to the present moment, distributed in south-eastern Transylvania and south ...of the Carpathians, mainly in the Olt and Argeș basins. The finds here suggest the presence of several typological variants, while their inclusion in one main type is indicated by their general aspect and proportions. All are cast in closed bivalve moulds with the metal poured through the butt. Some were subjected to compositional analyses, such as the axe from Râșnov (cat. no. 14) with 5% Sn. In the case of two artefacts, the conditions of discovery are unknown, three are isolated finds, two are part of a hoard alongside a shaft-hole axe, and the remaining nine originate from various occupation contexts. Geographically-wise, two finds from south-eastern Transylvania come from Schneckenberg or Jigodin-type contexts and seven artefacts recovered south of the Carpathians originate from Glina-type settlements. We may thus conclude that the Glina-type flanged axes represent a consistent group, well individualised in time and space. They constitute one of the arguments (alongside the Dumbrăvioara-type shaft-hole axes, the Runcuri-type pottery etc.) for the very close links between the Glina-type communities and those on the Upper Olt Basin, within a chronological horizon dated, most probably, between 2700 and 2500 BC.

Proizvodi na bazi kaolinske gline sve više se koriste u proizvodnji voća, a posebice onoj ekološkoj. Posljednjih godina prisutan je trend značajnog smanjenja broja dozvoljenih konvencionalnih ...sredstava za zaštitu bilja od štetnih organizama, što za posljedicu ima i postupni prijelaz s konvencionalne na ekološku proizvodnju voća. U ovom radu prikazane su mogućnosti korištenja proizvoda na bazi kaolinske gline u voćarstvu. Predstavljene su mogućnosti korištenja kaolinske gline u zaštiti od štetnika i bolesti, smanjenju ekološkog stresa uzrokovanog visokim temperaturama, zaštiti od ožegotina, povećanju uroda, poboljšanom obojenju i kvaliteti ploda. Kaolinska glina ima velike mogućnosti za unaprjeđenje voćarske proizvodnje u Republici Hrvatskoj, napose u ekološkoj proizvodnji, gdje zbog svoje široke primjene i učinkovitosti postaje praktički nezaobilazna.
Kaolin clay-based products are increasingly used in fruit growing, especially in organic farming. In recent years, the emphasis has been on a significant reduction in the number of conventional protective measures against diseases and pests. The gradual transition from conventional to organic fruit production is also noticeable. This paper presents the possibilities of using kaolin-clay based products in fruit growing. The possibilities of using kaolin clay to protect against pests and diseases, reduce environmental stress from high temperatures, protect against burns, increase yield, improve color and fruit quality are presented. Kaolin clay has great potential for improving fruit production in the Republic of Croatia, especially in organic farming, where its wide application and efficiency make it practically unavoidable.
This monograph presents the fundamentals of the mineralogy and geology of clays. The chemical or isotopic composition and the crystalline structure of clays is based on some relatively simple laws. ...Abundant illustrations help to understand the subject and can be used in courses. The organization of the book follows a logical structure. From the representation of the structure of minerals, the determination of their crystalline state by using X-ray diffractometer measurements (and other techniques) the thermodynamic and kinematic conditions of their formation is reconstructed. Then the genesis and alteration of the clays at their natural occurrences is discussed. In the last chapter it is stressed that clay minerals can form in variety of different environments: meteorites, lavas, subduction zones for example.
The book is aimed for graduate students and scientists (geologists, geographers, engineers, environmental and soil scientists) who want to get a comprehensive introduction in the topic.
U radu se navode i analiziraju obilježja povijesno-prostornog razvoja Gline od njezina osnutka tridesetih godina 18. stoljeća izgradnjom bastionske utvrde na ušću rijeke Maje u Glinu, do sredine 19. ...stoljeća, kada je formirana osnovna urbana struktura mjesta sa svim svojim vrijednostima na kojima počiva kulturnopovijesni i prostorni identitet današnjega grada. Razvoj Gline prati se na temelju poznatih i nekoliko dosad neobjavljenih kartografskih izvora.
In this contribution the author presents a batch of stone curved knives from the settlement of Glina-La Nuci, Ilfov County. They belong to the old collections of National Museum of Antiquities and ...are a part of a larger effort to recover unpublished data and artefacts from this settlement investigated by known figures of Romanian archaeology such as Ion Nestor, Mircea Petrescu-Dâmboviţa or Eugen Comşa. In addition to the description of the artefacts, the origin, distribution and possible functions of this type of object are briefly discussed.
The article describes the circumstances that led to the revival of sports events in the territory of the Republic of Srpska Krajina in the second half of 1992, temporarily interrupted due to the war. ...First competitions started in football, by far the most popular sport. After the first part of the competition had ended according to the regional principle, the winners of the five regional competitions met at the final tournament in Glina at the beginning of August 1993. The title of the first champion of RSK was taken by the host team, Banija from Glina, ahead of Šparta from Beli Manastir. The paper was written on the basis of press and publications from Krajina and sports press from Serbia, relevant literature, material from Croatian archives and published memories.
Cohesive soils are found all over the world and can cause significant harm to infrastructure and structures. Many innovative ways to improve the strength of cohesive soils are being explored to ...decrease the negative qualities and make them appropriate for construction applications. The availability of novel materials, in addition to traditional procedures, has boosted the area of soil reinforcement. In the realm of soil stabilisation, the inclusion of nanomaterials is one of the newest creative ideas. In geotechnical engineering, nanotechnology could be viewed as dual methods: the composition of the soil can be found at the nanoscale, and soil modification can be accomplished at the atomic and molecular levels. The goal of this research is to see if it is possible to stabilise cohesive soil using two distinct nanomaterials and to look at the changes in geotechnical parameters. Nanocrystalline magnesium oxide and nano zinc oxide is included in the soil with (0.25, 0.5, 0.75 and 1) w/% and trials were executed to evaluate the optimal percent and strength properties of the mixtures.
