Developing a LCA software in Hungary

In Hungary the first steps of LCA application can be observed. The objectives of the project are to establish a fundamental online database of LCA compatibility with international software. This database can help designing from the aspect of environment and can be used in education and research. We have classified the domestic power plants on the basis of applied technology and energy sources. But data collection presents some difficulty. Complex analysis of electric- and electronic equipment would be another important scope of the system. And we would like to popularize the LCA application for the small and medium sized enterprises

Az év vadvirága 2014-ben: a szibériai nőszirom (Iris sibirica L.) = The Wildflower of the Year 2014 in Hungary: Siberian flag (Iris sibirica L.)

Abstract – In this paper a review of the nomenclature, etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, application possibilities and conservation status of Siberian flag (Iris sibirica L.) can be found. Leaf traits, phenological data, seed-set, thousand-seed weight, germination, growth rate and soil characteristic data are published based on original observations: • Leaf area is between 25,3 and 52,9 cm2, its dry mass is 232 and 272 mg/g, specific leaf area is 14,5 and 15,0 m2/kg; based on measurement of 5–5 leaves of I. sibirica, collected from Tapolca and Létavértes (Hungary) in May of 2014. • Based on herbarium dataset, blooming of I. sibirica begins at the end of April and lasts to early-July, contrary to the literature data (May–June). • Capsules contain (0–)58–76(–121) fertile seeds. (20–)60–80(–90)% of ovules develops to (seemingly) viable seeds, meanwhile the other ovules remain as aborted ones or develop to infertile seeds (probably because of absence of resources); based on fruits collected from Regéc (Hungary) in 2014 and 2015. • Thousand-seed weight of I. sibirica is 8,8298–11,2914 g (based on 3×100–100 seeds collected from Regéc and Tapolca in 2014 and 2015), which is lower value than the literature data. • In our germination test (50–50 seeds sowed to wet soil, after different treatments) 14% of scarified seeds, 6% of scalded seeds, 4–4% of imbibed and control seeds, 0–0% of cooled and refrigerated seeds are germinated. Scarified seeds germinated in the 8–26th days, imbibed seeds 15–19th days, control seeds 16–20th days, scalded seeds 20–23th days after sowing. It seems that scarification stimulates, meanwhile temperature-treatments inhibit the germination. Until 18 weeks the seedlings grow to 30 cm (in mean) and develop 5–7 leaves (in mean). After the 14th week, the first and littlemost lateral leaves are necrosed. • Analyses of soil samples collected from 17 locations of I. sibirica in Hungary, suggest that the species prefers highly acidic to slightly alcalic, lime-free to highly calcareous soils with generally high amount of humus and clay, different amount of phosphorus, potassium and nitrogen and low concentration of salt.

Accident-Induced absence from work and wage growth

How do short absences from work affect workers’ labor trajectory? We use linked employer-employee administrative data from Hungary, with rich administrative health records, and use unexpected and mild accidents with no permanent labor productivity losses as exogenous drivers of short absences. Our Differencein-Differences results show that, relative to the counterfactual of no accident, even short (3–6-months long) periods of absence due to accidents decrease wages for up to two years by 1.5 percent, and workers end up with lower-paying firms. Missed opportunities to move to higher-paying firms account for 7–37 percent of the wage loss over a two-year period

An annotation tool for academic literature processing

In this paper, we present our annotation tool that facilitates research and annotation work by quick, yet efficient literature processing. Our tool helps users create a unique and refined collection of linked information, which can lead to more effective and faster decisions in research. The tool is currently optimized for biomedical domain, but it can adapted to other academic fields with minimal efforts

Pótlások Magyarország edényes növényfajainak elterjedési atlaszához III.

Jelen közleményünk annak a sorozatnak a harmadik része, melynek célja a Magyarország edényes növényfajainak elterjedési atlasza térképeinek kiegészítése, főként aktuális előfordulási adatokkal. Ezúttal 558 edényes taxon előfordulási adatait közöljük az ország szinte egész területéről (mintegy 186 flóratérképezési kvadrátból), de legnagyobb számban az Északi-középhegységből. Az adatok között ritkább őshonos taxonok (például Marsilea quadrifolia, Salicornia prostrata, Stellaria palustris, Potentilla patula, Althaea cannabina, Lythrum tribracteatum, Ajuga laxmannii, Plantago schwarzenbergiana, Alisma gramineum, Gagea bohemica, G. szovitsii), ritka, vagy legalábbis adathiányos idegenhonos fajok (például Chorispora tenella, Thladiantha dubia, Senecio vernalis) mellett országosan elterjedt, de többé-kevésbé alulreprezentált fajok (például Scleranthus annuus, Vicia hirsuta, V. lathyroides) esetében is közöljük az Atlasz térképeihez képest újnak bizonyuló lelőhelyeket. A legközönségesebb fajok esetében a lelőhelyek részletezése nélkül csupán KEF-kódokat adunk meg.</jats:p

Changes in Total Polyphenol Content and Antioxidant Capacity of Stinging Nettle (Urtica dioica L.) from Spring to Autumn

Total polyphenol content and antioxidant/reducing capacity of stinging nettle (Urtica dioica L.) leaves and roots collected from wild-grown plants were investigated during the vegetation period. From both fresh and dried samples of leaves and roots, water extracts were prepared by brewing at 60, 80 and 100 °C for 3 hours, and ethanolic extracts of 20 % (v/v) and 70 % (v/v) by extracting at room temperature for 72 hours. The total polyphenol content was determined spectrophotometrically with Folin-Cioceltau reagent and the antioxidant capacity was measured by ferric reducing ability of plasma (FRAP) assay. Our results showed that the optimal harvest time is in the spring (April). Water extracts had the highest total polyphenol content and antioxidant capacity in this period. The amount of valuable compounds released increased by higher extraction temperature in both plant parts. In water extracts of nettle leaves, two times higher polyphenol content was obtained than in that of roots. Both kind of ethanolic extractions resulted in a higher polyphenol content in the leaves harvested in the spring period. For the roots, it was higher for samples collected in the autumn, which is also reflected in the values of antioxidant capacity. Water extracts of fresh leaves harvested in April had more than twice higher total polyphenol content than in October. For dried samples, raising the temperature did not cause a significant change in the total polyphenol content, however, it has resulted in increased antioxidant capacity both for the dried leaf and root samples
