Some preliminary results regarding average values of the upper and lower bounds of the foF2 variability over Europe are reported. Their dependence on time of day and season is shown. It is inferred that a quantitative description of the ionospheric variability although difficult, is however essential for modern terrestrial and satellite communications applications.

This paper presents the preliminary results of an empirical study aimed at exploring the effect of previous preparation in the performance of simultaneous interpreting of specialised speeches, carried out with advanced undergraduate interpreting students. Simultaneous interpretation may be the most frequent modality of interpretation used in multilingual specialised and technical conferences, including international scientific conferences. The linguistic and extra-linguistic characteristics of specialised speeches impose additional demands on comprehension processing. Previous preparation is here understood as an instance of acquisition of prior topic knowledge, which has been observed to support the comprehension of scientific discourse. A within-subject design was used to test the effect of an instance of previous preparation on neutral and difficult segments of a scientific speech. Ear-voice-span (EVS), translation accuracy and percentage of omissions were measured as dependent variables on which previous preparation had a significant effect.

Abstract  

Preliminary testing of dissolved air flotation (DAF) for wastewater treatment is presented. A combined coagulation-flocculation/DAF column system is used to remove oil and 60Co from nuclear industry wastewater. In this work, operational conditions and coagulant/flocculant concentrations are optimized by varying pH. Determinations of air-solids ratio (G/S), retention time (θ), pressure (P), volume of depressurized air–water mixture (V), turbidity and 60Co concentrations are reported. The effect of the treatment on the efficiency of separation of oily residues is also discussed. The results establish that the coagulant/flocculant system, formed by a modified polyamine (25 mgL−1) and a slightly cationic polyacrylamide (1.5 mgL−1), under specific operational conditions (pH = 7, mixing intensity Im1 = 300 s−1 and Im2 = 30 s−1), allowed the destabilization of colloidal matter, resulting in resistant flocs. It was concluded that by using G/S = 0.3, θ = 15 min, P = 620 kPa and V = 0.0012 m3, the greatest percentage removals of oil, turbidity, total cobalt and 60Co were obtained. These preliminary results then show that dissolved air flotation represents a good alternative for treatment of nuclear industry wastewater contaminated with radionuclides.

Summary

During rescue excavations carried out near the vicus at Kempraten (municipality of Rapperswil-Jona, St. Gallen, Switzerland) in advance of a private construction project, a Mithraeum measuring approximately 8 by 10 m was unexpectedly discovered in the summer of 2015 and subsequently excavated and investigated in detail. This paper presents the preliminary results of the excavation, which was completed less than a year ago, and pays particular attention to the interdisciplinary approach used in the excavation. These included intense sampling of the features for the purposes of micromorphology and archaeobiology. Three construction phases with intermittent conflagrations were identified. The question as to whether there was an ante-chamber remains unanswered. The external areas are also quite difficult to interpret, at least for the time being. The rich assemblage of finds, which included numerous coins, pottery, animal bones and a range of religious artefacts (e.g. altars and a half relief), will only be dealt with in a cursory manner here. According to the range of coins, the Mithraeum undoubtedly dated from the late 3rd to the late 4th or early 5th centuries. The site will be analysed by an interdisciplinary team and preliminary work is already underway.

The potential of the most recent membrane technology is still unaccounted for in many respects. Combining fermentation with up-to-date membrane technology building a membrane bioreactor allows the adjustment of the cell count on a high level, increasing yield per volume and time. Applied to beer manufacturing, main fermentation times of less than 20 h seem possible, avoiding the disadvantages of already known accelerated fermentation processes operated on a continuous basis. Although module design was adapted and backwash procedure altered to gas-jet, maintaining a sufficient membrane flux over time still poses a major problem. Nevertheless, preliminary results in respect of beer quality look promising.

In order to define the normal composition of canine amniotic fluid and to detect differences between surviving and non-surviving newborn puppies, the present study determined the uric acid, glucose, lactate and creatinine concentrations and the lactate to creatinine ratio in amniotic fluids collected during elective Caesarean section from small-sized purebred bitches. The possible relationship between newborn survival and the studied parameters, as well as the effects of maternal parity, fetal gender and Apgar score were assessed. The study enrolled 27 small-sized purebred bitches submitted to elective Caesarean section at term. After opening the fetal membranes, amniotic fluid samples were collected aseptically from the amniotic sac of each fetus. The data obtained from 74 amniotic fluid samples collected from 27 bitches showed that amniotic glucose concentration was lower (P < 0.05) in non-surviving than in surviving puppies. Within the normal, surviving puppies, amniotic glucose concentration was higher (P < 0.05) in male than in female newborns, and the lactate/creatinine ratio was significantly higher in multiparous than in primiparous bitches (P < 0.05). These preliminary results demonstrate the relevance of amniotic glucose, but not of uric acid, lactate, creatinine and the lactate to creatinine ratio for detecting puppies at risk of death immediately after birth.

Bevezetés: Nemzetközi és hazai kutatások egyaránt igazolják, hogy a pszichoszociális stressz mentális megbetegedések kockázati tényezője. Célkitűzés: Jelen tanulmány célja az Országos Munkahelyi Stresszfelmérés előzetes eredményeinek feldolgozása a depressziós tünetegyüttes és a stresszterhelés kapcsolatának vonatkozásában. Módszer: Keresztmetszeti kérdőíves vizsgálat magyar munkavállalók körében (n = 1058, 27,5% férfi, 72,5% nő, átlagéletkor 37,2 év, SD = 11). A pszichoszociális tényezőket a COPSOQ II (Koppenhágai Kérdőív a Munkahelyi Pszichoszociális Tényezőkről II), míg a depressziós tünetegyüttest a rövidített Beck Depresszió Kérdőívvel mértük fel. A pszichoszociális tényezők és a depresszió kapcsolatát korrelációval, illetve bináris logisztikus regresszió analízissel vizsgáltuk. Eredmények: A minta negyede közepesen súlyos vagy súlyos depressziós tünetekről számolt be. Az eredmények igazolják a depressziós tünetegyüttes (BDI≥19) összefüggését a munka–család konfliktussal (OR = 2,21, CI: 1,82–2,68), a fejlődési lehetőségekkel (OR = 0,76, CI: 0,59–0,97), a munka értelmességével (OR = 0,69, CI: 0,59–0,89) és a munkahely iránti elkötelezettséggel (OR = 0,60, CI: 0,47–0,78). Következtetések: A munkavállalók mentális egészségének védelme szempontjából az eredmények felvetik olyan szervezeti szintű intézkedések szükségességét, amelyek lehetővé teszik a pszichoszociális stressz csökkentését.

A tanulmány célja, hogy bemutassa a Rövid Stressz Kérdőív kifejlesztésének első lépéseit, valamint a kérdőívvel kapcsolatos előzetes eredményeket. A kérdőív fejlesztésének célja az volt, hogy gyors, néhány perc alatt kitölthető, a hétköznapi stressz mértékének szűrővizsgálati jelleggel való becslésére alkalmas mérőeszközt hozzunk létre. A kérdéseket részben a Rahe-féle Stressz és Megküzdés Kérdőív rövidített változata egyes kérdéseinek felhasználásával, részben 156, stresszkezelő tréningen vagy egyéni tanácsadáson részt vett személlyel készült félig-strukturált interjú alapján állítottuk össze. Előzetes eredmények: A kérdőívvel kapcsolatos előzetes tapasztalataink biztatóak, a kérdőív belső konzisztenciája magas (Cronbach-alfa 0,82), a depressziós és szorongásos tünetekkel mért korrelációja a diszkriminációs érvényesség mellett szól, amely alapján feltételezhető, hogy a kérdőív nem pusztán a szorongásos és depressziós tüneteket, vagy azok következményeit méri, hanem önálló konstruktum. Következtetések: a Rövid Stressz Kérdőív ígéretes eszköz lehet a jövőben a hétköznapi stressz szűrésére, pontos használhatóságát azonban a jelenleg folyamatban lévő, nagyobb elemszámú további vizsgálatok hivatottak igazolni.
