Analiza metoda za kvantifikaciju suše

Extreme climatic events such as drought, in many parts of the world are causing great damage to the economy and even wider. An analysis of this event is of great importance to all those who are exposed to its influence. Drought indices seem to be the simplest tool for its analysis. Four drought indices were used: De-Martonne drought index, Standardised Precipitation Index, Standardised Precipitation-Evapotranspiration Index and Rainfall Anomaly Index. The analysis was conducted for the meteorological station Rimski Šančevi, over the period 1971-2014. The results indicate shifting of dry and wet years, and the correlation shows to what extent these indices can represent each other's alternative.Ekstremne klimatske pojave poput suše, u mnogim delovima sveta nanose velike štete privredi, pa i šire. Analiza ove pojave je od velikog značaja za sve one koji su izloženi njenom uticaju. Indeksi suše se čine najjednostavnijim alatom za njenu analizu. U radu su korišćena četiri indeksa suše: De-Martonne-ov indeks suše, standardizovani indeks padavina, standardizovani indeks klimatskog vodnog bilansa i indeks anomalija padavina. Analiza je sprovedena za meteorološku stanicu Rimski Šančevi, za period od 1971-2014. godine. Rezultati ukazuju na smenjivanje sušnih i vlažnih godina, a korelaciona analiza pokazuje u kojoj meri ovi indeksi mogu predstavljati jedan drugome alternativu

Seed Dormancy in Sugar Beet (Beta vulgaris)

Abstract RAJIC, M., B. MARINKOVIC and Milica RAJIC, 2006. Seed dormancy in sugar beet (Beta vulgaris). Bulg. J. Agric. Sci., Studied in this paper was how germination energy, germinability and absolute 1000-seed mass of sugar beet seeds was affected by ten different growing locations and seed storage in controlled and uncontrolled conditions for 150 days following harvesting. Over the three study years, significant differences were obtained within each of the factors studied, with no interaction among the factors. The uncontrolled conditions of seed storage in silos produced a highly significant positive difference in seed quality relative to the controlled conditions of laboratory storage. The same difference was obtained with the storage times of December, November and September relative to July. Highly significant differences were found among most of the growing locations, while in a smaller number of them the differences were not significant The significant differences consisted in increased germination energy and germinability and decreased absolute seed mass

Hollis Croft, Sheffield, South Yorkshire: Old site and new connections

In 2017, a team from the Wessex Archaeology Sheffield office investigated a site, Hollis Croft (NGR 434990 387580), prior to the construction of a multi-million pound commercial and student housing development. Hollis Croft is one of many Sheffield’s sites where well-preserved industrial archaeology survives beneath the modern buildings. Historic building recording was followed by a watching brief, a scheme of archaeological evaluation trenching and then strip, map and sample excavations, which revealed substantial 18th-/19th-century remains of steel conversion furnaces (both cementation and crucible, constructed by Burgin and Wells and W. Fearnehough Ltd respectively). We also discovered metres of entwined brick-built flues (likely related to later steelmaking methods such as the Siemens-Martin open hearth process or Bessemer process), traces of two pubs (The Cock and The Orange Branch) and a wide range of finds – all indicative of the industrial processes and the everyday lives of the workers. Apart from the discovery of a crozzle layer covering the entire interior of the furnace (not just its base as previously thought), and the detailed impressions of the ferrous bars visible in the surface of the crozzle layer, the remains were very familiar for Sheffield and industrial archaeology. The post-excavation processes were carried out as usual following industry standards. All our findings have been brought together in a final report held in the digital archive and the physical archive (including the finds) was subsequently deposited with Museums Sheffield under SHEFM:2019.13 and Sheffield Archives. This publication is based on that final report, but edited and updated, so there are some minor differences between the documents. But, inspired by a great deal of public interest during the excavations (and Mili's love for comics), a comic book has also been created and is published here alongside what would otherwise be a more traditional offering

Hollis Croft, Sheffield, South Yorkshire. Archaeological Excavation (OASIS ID: wessexar1-309354)

The remains of two well-preserved mid- to late-19th century cementation furnaces were recorded. The refractory chambers ('chests') of the furnaces had been replaced, probably due to an inadequate provision of flues in the original design. Details of the furnaces were recorded, including the stoke hole entrance doors and the arrangement of 'fire bars' upon which fires were set in the underlying ash pits of the furnaces. Metallurgical analysis supported the view that the refractory lining of the chests (the 'crozzle') was derived from 'wheelswarf' produced by edge tool grinding. For the first time, it was confirmed that this crozzle extended up the interior sides of the refractory chamber. Another apparently new observation is that of the impression of the ferrous bars in the surface of the crozzle layer. Two crucible furnaces were identified. The crucible furnaces could not be closely dated. The cementation furnaces and crucible furnaces were part of separate works and there is no evidence to relate them. To the north of the cementation furnaces was an area of slightly later development characterised by the use of black ash mortar rather than lime mortar. This area included extensive cellars supporting a network of flues. Domestic housing and public houses were also investigated. The pottery assemblage was unusually broadly dated for Sheffield and represents a significant result. The clay tobacco pipe assemblage was of interest and examples of pipes were illustrated. A medieval penny was also recovered from a 19th century context. This archive contains a final report, two interim reports and three written schemes of investigation. The original site records have been scanned and are included alongside the record photographs and CAD survey of the excavations. The original paper archive has been deposited with Museums Sheffield (accession number SHEFM:2019.13) alongside the artefact collection. A retention and selection policy for artefacts was agreed by Wessex Archaeology and Museums Sheffield
