Prema službenoj se evidenciji tikvenjače u Hrvatskoj uzgajaju na 5 000 do 7 000 hektara. Znatno dominira uzgoj uljne buče (cca 70%) i lubenice (cca 10%). Korovi su važan ograničavajudi čimbenik ...proizvodnje. Izbor je herbicida ograničen. Ovisno o vrsti tikvenjače, registrirani su samo S-metolaklor, petoksamid, pendimetalin, napropamid, klomazon i cikloksidim. Kemijske se mjere borbe zbog ograničena izbora herbicida i nepotpuna spektra djelovanja uobičajeno u praksi kombiniraju s mehaničkim mjerama (međuredna kultivacija, okopavanje) te, kod manje zastupljenih vrsta, s uzgojem na foliji. Nekemijske mjere (živi i mrtvi malč, slijepa sjetva i dr.) treba istražiti u hrvatskim pedo-klimatskim uvjetima.
Uljna buča (Cucurbita pepo L.) ima dugu tradiciju uzgoja u Hrvatskoj, a zbog isplativosti proizvodnje povedava se interes za njezinim uzgojem. Prinosi sjemenaka uljne buče variraju u velikom rasponu ...od 500 do 1200 kg suhog sjemena po hektaru, u čemu veliku ulogu ima i uspješnost suzbijanja korova. U radu je opisana botanička pripadnost, morfologija i biologija te tehnologija uzgoja uljne buče. Prikazani su najčešdi korovi i njihov utjecaj na prinos i komponente prinosa u usjevu uljne buče, kritično razdoblje zakorovljenosti te čimbenici koji na njega utječu.
ÖZ: Az gelişmiş ve gelişmekte olan ülkelerdeki kırdan kente göç olgusu, kentsel alanlarda birçok mekânsal, sosyal, ekonomik ve kültürel değişimi meydana getirmiştir. Türkiye’de 1950'li yıllarda öne ...çıkan gecekonduların sayıları, sonraki on yıllarda artmış ve birçok gecekondu mahallesi oluşmuştur. İzmir, söz konusu dönemde gecekondu mahallelerinin yaygınlaştığı metropol kentlerden birisidir. Gecekondular başlangıçta kent merkezine yakın mahallelerde oluşturulurken, zamanla kentin dışına doğru yayılım göstermiştir. İzmir’in Buca ilçesindeki Kuruçeşme Mahallesi, iç göçlerle oluşmuş eski bir gecekondu mahallesidir. Mahallede son yıllarda, kentsel dönüşüm uygulaması adı altında yıkılan gecekondu ve eski binaların yerini yeni inşaatlar ve binalar almıştır. Bu çalışmanın amacı, metropol kentin çeperindeki eski bir gecekondu mahallesindeki dönüşüm dinamiklerini ve ortaya çıkan çelişkileri analiz etmektir. Buca, kentleşme ve gecekondulaşma sorunlarının öne çıktığı yoğun nüfuslu bir yerleşim yeri olmasına rağmen, bu konuda bilimsel çalışmalar sınırlıdır. Dolayısıyla bu çalışmanın literatüre önemli bir katkısının olması hedeflenmektedir. Sahadan elde edilen bulgulara dayanan betimleyici bu çalışmada; nicel ve nitel araştırma yöntemleri ve bu yöntemlerin teknikleri bir arada kullanılmıştır. Çalışma kapsamında, Kuruçeşme Mahallesi’ndeki 350 haneye yapılandırılmış soru kâğıdı uygulanmış ve 20 kişiyle de yarı yapılandırmış derinlemesine görüşmeler gerçekleştirilmiştir. Eski bir gecekondu mahallesi olan Kuruçeşme Mahallesindeki dönüşüm, konut piyasası üzerinden şekillenen ranta dayalı birikim rejiminin, kentin çeper bir yerleşiminde de yaşama geçirildiğini göstermektedir. Bu dönüşümün mekâna, nüfusa, sosyal ve ekonomik ilişkilere etkisi ve de çelişkileri, araştırmanın bulguları ışığında analiz edilmiştir. ABSTRACT: The phenomenon of rural-urban migration in underdeveloped and developing countries, have brought about many spatial, social, economic and cultural changes in urban areas. Number of prominent slums in the 1950s in Turkey, have increased in the next decades, and many slums has occurred. Izmir was one of the metropolitan cities where slums became widespread during that period. While slums were initially created in neighborhoods close to the urban center, over time, they spread out of the urban. Kuruçeşme Neighborhood in Buca district of Izmir is a former slum neighborhood formed by internal migration. In recent years, the slums and old buildings that were demolished under the name of "Urban Transformation" practice, have been replaced by new constructions and buildings. The aim of this study is to analyze the transformation dynamics and emerging contradictions in a former slum neighborhood on the periphery of the metropolitan city. Although Buca is a densely populated settlement where urbanization and squatting problems stand out, scientific studies on this subject are limited. Therefore, this study is aimed to make an important contribution to the literature. In this descriptive study based on the findings obtained from the field; quantitative and qualitative research methods and the techniques of these methods were used together. Within the scope of the study, a structured questionnaire was applied to 350 households in Kuruçeşme Neighborhood and semi-structured in-depth interviews were conducted with 20 people. The transformation in Kuruçeşme which is a former slum neighborhood, shows that rent-based accumulation regimeshaped over the housing market was also implemented in a peripheral settlement of the city. The effects and contradictions of this transformation on space, population, social and economic relations have been analyzed in the light of the findings of the research.
During the Quaternary several glaciations occurred in the mountain regions around the Mediterranean and, in recent years, new ages have better constrained their timing. However, this is not the case ...for the Apuan Alps, a high-rainfall mountain chain adjacent to the Mediterranean Sea. Here, in spite of the widespread evidence for glaciers, the complete lack of geochronological information hinders our understanding of glaciation history. In this paper, we utilize speleothem ages to better constrain the timing of these glacial features. We re-examine 293 uranium‑thorium ages from 19 speleothems collected in five caves at different elevations. After a period of very low growth between 160 and 132 ka, the analysed speleothems grew almost continuously to ~75 ka, this period was followed by intermittent growth with lower deposition rate and presence of hiatuses until ~12.5/12 ka. This is consistent with an ice coverage persisting over the Apuan Alps, inhibiting or interrupting the growth of speleothems via the limited availability of groundwater and the scarcity/absence of soils. This interval is much greater than the time interval that has previously been attributed to the existence of glaciers on the Apuan Alps, which has been assumed to be restricted to Marine Isotope Stage (MIS) 2. Instead, ice cover probably also appeared in the Apuan Alps during MIS 4. The phase of restarting of growth, which may implies the definitive or substantial glacier melts seem to predate the Holocene.

•Trace element incorporation into pyrite is facilitated by enrichment of antimony.•As pyrite recrystallizes, trace element contents vary based on element availability.•Retrograde ...cooling and annealing causes liberation of trace elements from pyrite.•Trace elements released from pyrite form sulfosalts sometimes mobilised as melts.•More than 250 tons of thallium may have been released from pyrite in some ores.
Several small pyrite ± baryte ± iron-oxide orebodies (Buca della Vena, Canale della Radice, Fornovolasco, Monte Arsiccio and Pollone) are hosted in the metamorphic rocks of the southern Apuan Alps, northern Tuscany, Italy. These deposits are exceptionally thallium-rich, expressed in part by assemblages comprising rare Tl-sulfosalts. Using a variety of techniques including laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) on fifty-four samples, the textural and trace element evolution of pyrite during greenschist facies metamorphism has been described. Five generations of pyrite have been recognised. Pyrite-1 (py1) and pyrite-2 (py2) (framboidal and colloform pyrite, respectively) likely represent pristine generations and are rich in trace elements. Pyrite-3 (py3) forms fine-grained disseminations often aligned with the metamorphic fabric and likely formed during the earliest stages of deformation associated with metamorphism. Pyrite-4 (py4) forms coarse, euhedral, inclusion-rich crystal clusters and likely formed as pristine pyrite generations began to recrystallize. Pyrite-5 (py5) is typically coarse, relatively ‘clean’ and often euhedral. It is interpreted to be the end-product of pyrite recrystallization, with grain size increasing and micro-inclusions being expelled late on the prograde path, then granoblastic annealed textures forming during retrograde cooling. Pyrite (especially primary pyrites; py1 and py2) is particularly rich in As (up to 17,400 ppm), Sb (up to 5100 ppm) and Tl (up to 4200 ppm), while Ni, Pb and Mn may be present above 1000 ppm, and Hg, Co, Cu, Zn, Mo, Bi and Ag may all be present above 100 ppm. Some trace elements, particularly As, Ni and Co, are commonly zoned in late metamorphic pyrite overgrowths. The incorporation of some trace elements into pyrite seems to have been facilitated by the presence of Sb in a similar way that As generally facilitates Au incorporation. Concentrations of most trace elements decrease from py3 to py4 at Fornovolasco and Monte Arsiccio, while in the other deposits the opposite trend is observed. Concentrations of most trace elements drop significantly from py4 to py5, where recrystallization of pyrite liberates a large proportion of As, Sb, Tl, Pb, Hg, Cu, Zn, Ag and Mn, likely during retrograde cooling and annealing. The release of these elements from pyrite during metamorphic recrystallization has directly facilitated the formation of late-stage sulfosalts, especially at Monte Arsiccio, where textural evidence suggests sulfosalt assemblages intimately associated with py5 were mobilised as melts during greenschist facies metamorphism. At Monte Arsiccio, around 75% of Tl hosted in early recrystallized pyrite is released upon complete recrystallization. As such, mass balance calculations show that all Tl contained in Tl-sulfosalts could be supplied from locally recrystallizing pyrite, and that in total, more than 250 tons of Tl could potentially have been liberated from the pyrite orebody at Monte Arsiccio during metamorphism. This study highlights the significant quantities of Tl and other metals that may be hosted in pyrite, and also the potential role that metamorphic recrystallization may play in mobilising and (re)-concentrating (or indeed dispersing) metals in a pyrite-dominant ore system.
Bohuslavite, Fe3+4(PO4)3(SO4)(OH)(H2O)10·nH2O, was first described from the Buca della Vena mine (Apuan Alps, Tuscany, Italy) and from the Horní Město deposit (northern Moravia, Czech Republic). Its ...full characterization was a difficult task, owing to the very low diffraction quality of available material. Notwithstanding a physically reasonable structural model, some issues remained uncertain. A new intensity data collection on a sample from the Buca della Vena mine allowed us to improve our knowledge of the crystal structure of bohuslavite. This mineral is triclinic, P1, with unit-cell parameters a = 13.3722(15), b = 13.3488(18), c = 21.585(3) Å, α = 92.345(6), β = 90.153(8), γ = 120.34(2)°, V = 3321.2(11) Å3, Z = 4. The crystal structure of bohuslavite has been refined to R1 = 0.1498 on the basis of 19,578 unique reflections with Fo > 4σ(Fo) and 773 refined parameters. The actual (SO4) distribution is clarified, as well as the role of some H2O groups, whereas some minor details remain to be solved.
