V zadnjih dvajsetih letih je zeliščarstvo postalo večfunkcijska proizvodno-storitvena dejavnost, v kateri se prepletajo podjetništvo, tradicionalno znanje, kmetijstvo, varovanje naravnega okolja in ...sodoben način življenja. Ključni, relativno nov akter slovenskega zeliščarstva, so zeliščarji-podjetniki, ki na tržišče vstopajo z različnim znanjem in trženjskimi pristopi. S kvalitativno analizo polstrukturiranih intervjujev z zeliščarji-podjetniki smo za vsako podjetje izdelali kvalitativni profil in shematiziran prikaz podjetniških in trženjskih značilnosti (raznovrstnost ponudbe, prodajni kanali, možnost za širitev ponudbe, promocija, povezovanje in mreženje ter razpoložljivost delovne sile in vprašanje nasledstva). Le-te so močno odvisne od značilnosti nosilca dejavnosti, in sicer njegove starosti, zaključene formalne stopnje izobrazbe, starosti podjetja in podjetniških izkušenj ter razlogov za ustanovitev podjetja. Za uspešno delovanje zeliščarjev-podjetnikov so ključne njihove povezave z lokalnim in širšim (poslovnim) okoljem.
Background. Spontaneous miscarriage isn’t an unexpected complication either in early spontaneous or in ART pregnancy. Previous studies showed that incidence of SM was slightly increased in ART ...pregnancies in comparison with spontaneous ones after adjusting for maternal age and previous SM. Our objective was to examine the relationship between SM and embryo quality after transfer of one or two blastocysts. Materials and methods. The total of 1433 stimulated IVF and ICSI cycles achieved in our center in the period from 2001 to 2002 after SBT or DBT were retrospectively analyzed. Of these, in the final analysis we included only cases with positive βhCG for which complete data on pregnancy outcome were available – 418 cycles in total. Results. The mean age of patients was 32.2 ± 4.5 years. IVF was performed in 133 cases and ICSI was performed in 285 cases, SBT in 69 and DBT in 349. After SBT, SM rate was 11.6 % and after DBT it was 12.0 %. In SBT group we didn’t find significant relationship between embryo quality and SM (logistic regression: c2 = 0.88; p > 0.05). In this groups, using standard statistical tests, we also couldn’t find significant difference in SM rate between subgroups where optimal or suboptimal quality blastocyst was transferred (Yates corrected c2 test: p > 0.05, Student’s t-test: p > 0.05). In DBT group, we found a strong relationship between embryo quality and SM (logistic regression: c2 = 10.12; p < 0.01). After standard analysis, we confirmed significant difference between subgroups with different combinations of blastocyst quality: after transfer of both optimal blastocysts SM rate was 8.5 %, after transfer of optimal and suboptimal blastocyst SM rate was 10.1 % and after transfer of both suboptimal blastocyst SM rate was 25.4 % (Kruskal-Wallis test: p < 0.001; one-way ANOVA: p < 0.001). We confirmed strong relationship between age of the patients and SM (logistic regression: c2 = 14.57; p < 0.0001). Conclusions. In our study SM rate was 11.9 % which was lower than in previous reports; it was even at the lower limit of expected SM rate in general population. This discrepancy was probably the consequence of longer selection period of blastocysts in in vitro conditions. We didn’t find a significant relationship between SM and blastocyst quality after SBT, which was probably due to the small sample size. A strong relationship between SM and blastocyst quality after DBT was proved. We also confirmed a strong relationship between age of the patients and SM.

Background. Multiple pregnancy can be prevented by an elective single blastocyst transfer. The aim of this prospective study was to evaluate the effect of blastocyst development and morphology on the ...outcome of single blastocyst transfer. Methods. In this study 157 women with single blastocyst transfer were included; their mean age was 33.6 years, range 20–42. Embryos were cultured to the blastocyst stage and evaluated using the Gardner’s classification. An elective single blastocyst transfer was performed in 83 women although 2 or more blastocysts developed (Group 1) and in 74 with only one developed blastocyst (Group 2). Results. In Group 1 (2 or more blastocysts) the pregnancy rate was a significantly higher than in Group 2 (1 blastocyst only) (39.8 % vs. 23.0 %; P < 0.05). After the transfer of a single expanded blastocyst no statistical difference in the pregnancy rate between the two groups was observed (45.5 % vs. 44.6 %). A significantly higher pregnancy rate was found after the transfer of one expanded blastocyst with a good embryoblast and trophoblast morphology compared to the transfer of a single early blastocyst (45.6 % vs. 7.1 %, P < 0.05). Conclusions. After single blastocyst transfer, the likelihood of achieving a pregnancy is higher in women with 2 or more blastocysts developed. And also the likelihood of achieving a pregnancy is higher with an expanded blastocyst transferred with good embryoblast and trophoblast morphology. The blastocyst development is the main predictor of pregnancy, which may reflect the embryonic genetic status.
The paper will present the implementation of a hybrid power supply for telecommunication and corresponding measuring equipment of remote measuring stations, which are an integral part of the flood ...protection system. Solar power is the primary energy source during the day, while in night conditions it is actually used as a distribution network (which also supplies street lighting). The power system is implemented with two controlled MPPT chargers (mains and solar), 12V / 110Ah battery bank and associated monitoring system. The paper will present key experimental results obtained during the release of a concrete realized measuring station and associated telecommunication equipment, on the Ub River, Ub Municipality.
Idiomatic expressions play an important role in communication. They are widely used in both spoken and written discourse and are often one of the indicators of native-like proficiency. This paper ...discusses Chinese idioms chengyu in foreign language education, presents some observations regarding the scope of idioms predicted for the advanced level of Chinese, and introduces conceptual gaps between L1 and L2 as possible reasons for learners’ mistaken usages. This study argues that equipping students with skills and knowledge needed for reaching contextually appropriate use of idioms should be the main goal in the teaching/learning process and provides a set of practical suggestions as to which aspects of teaching idioms should be considered thoroughly.
Članek predstavlja prvi izsek raziskovalnega dela pri ciljnem raziskovalnem projektu Priložnosti in možnosti za ohranjanje oziroma revitalizacijo slovenščine med slovensko manjšinsko skupnostjo v ...sosednjih državah, namenjenem preučevanju stanja slovenskega jezika v Beneški Sloveniji. V kontekstu globalizacijskih procesov, evropskih integracijskih procesov, ugodnejših in trdnejših zakonskih podlag (t. i. zaščitnega zakona) ter predvsem zaradi prisotnosti dvojezične šole lahko oblikujemo hipotezo, da v Beneški Sloveniji obstajajo ugodne okoliščine za jezikovno revitalizacijo in deasimilacijo mlajših generacij, kar vključuje tudi ponovno učenje slovenščine med generacijami, pri katerih je medgeneracijski prenos jezika zastal. Iz zbranih podatkov je mogoče izluščiti, da je v prejšnji generaciji medgeneracijski prenos jezika pogosto zastal z začetkom šolanja oz. vstopom v vrtec, ki je zaznamoval prehod na italijanski jezik. Tudi zato je dvojezično šolanje za Beneško Slovenijo pomemben dosežek, vendar samo po sebi še ni zadosten pogoj za ohranjanje ali oživitev medgeneracijskega prenosa jezika. Potrebni so še drugi ukrepi jezikovnega načrtovanja in jezikovne politike. Ob tem gre poudariti, da se ti procesi razvijajo v okolju, ki je bolj naklonjeno slovenščini in dvojezičnosti, kot je bilo v preteklosti.
Epidemija covida-19 (angl. coronavirus disease 2019), ki jo povzroča virus SARS-CoV-2 (angl. SARS coronavirus 2), je bila v Sloveniji razglašena v sredini marca 2020 in je znatno spremenila ...zdravstveno obravnavo. S ciljem zajeziti širjenje covida-19 so bile potrebne prilagoditve v zdravstvenih ustanovah, tudi v otorinolaringoloških. Prilagodila se je tudi avdiovestibulološka obravnava (tj. obravnava bolezni sluha in ravnotežja) ter otokirurška obravnava (tj. kirurška obravnava bolezni ušes in temporalne kosti), ki predstavljata visoko tveganje za prenos virusa SARS-CoV-2. Virus se namreč v največji meri prenaša preko zgornje aerodigestivne cevi, pomembni pa so tudi drugi načini prenosa. Pri otokirurških posegih nastaja aerosol, ki lahko vsebuje virus SARS-CoV-2. Poleg tega je otorinolaringolog med avdiovestibulološko in otokirurško obravnavo večinoma v neposrednem bližnjem stiku s potencialno kužnimi izločki bolnika. Namen tega prispevka je predstaviti posebnosti avdiovestibulološke in otokirurške obravnave v času epidemije covida-19, ki so nastala na osnovi naših izkušenj v terciarni otorinolaringološki ustanovi, in tudi tuje literature. V prispevku so navedene indikacije za avdiovestibulološko in otokirurško obravnavo ter opisane nekatere prilagoditve otokirurških tehnik, ki temeljijo na poznavanju možnih načinov prenosa virusa SARS-CoV-2.
This work is focused on a quantitative procedure for estimating the generally unfavourable effects that incorrectly drilled holes, characterized by the initial clearance between a rivet and a hole, ...have on the fatigue life of riveted joints. The solution is based on an analytical approach using the stress-severity-factor concept. An experimental programme with riveted-joint specimens characterized by low-load transfer factors was realized in the Czech Aerospace Research Centre (VZLU) test lab under constant amplitude loading. The holes for rivet joints with 4-mm diameters were prepared with the clearance in a range of 0.0–0.16 mm. Force-controlled riveting was applied using a constant pressure force to form the driven head. To prevent fretting events between the joined parts, their anodized contact surfaces were lubricated with MOLYKA, plastic grease with molybdenum disulphide and graphite. The experimental data showed that the load-transfer factor and the fatigue life depend on the initial clearance between a rivet and a hole. The presented procedure introduced the hole-filling factor, integrated in the stress-severity-factor concept as a function of the initial clearance between a rivet and a hole.
Nacionalne vlade in mednarodne ustanove v zadnjih desetletjih iščejo načine, kako bi odpravile razlike med posameznimi regijami in revitalizirale tiste, katerih razvoj zaostaja za drugimi. Zamisli o ...najučinkovitejših načinih za doseganje teh ciljev in njihovi primeri izvirajo iz različnih krajev po svetu, njihov vpliv pa se običajno širi tudi drugam. Zato so procesi, povezani s prenosom politik, izjemno pomembni za regionalni razvoj. Avtor te procese v članku proučuje na primeru japonskega otoka Hokaido, in to v obdobju po drugi svetovni vojni, pri čemer posebno pozornost namenja vlogi treh mednarodnih strategij: modelu, ki ga je razvilo javno ameriško podjetje Tennessee Valley Authority, teoriji polov rasti in teoriji industrijskih grozdov. Z izsledki raziskave opozori na veliko pestrost akterjev, ki sodelujejo pri prenosu politik, analizira procese vključevanja zunanjih zamisli v politiko regionalnega razvoja in pokaže na široko paleto virov, iz katerih se akterji lahko učijo.
