Nezgode pri delu gozdarskih podjetij v Sloveniji pred in po letu 1993
No full textNezgode pri delu v gozdu so pogoste. Gozdarstvo tako spada v svetu in v Sloveniji med najbolj tvegane dejavnosti, kjer je varnosti pri delu vedno premalo. S primerjavo dveh daljših obdobij (1984 - 1992 in 1993 - 2005) so analizirali kdaj, komu, kako in zakaj so se nezgode pripetile, kakšne so bile posledice in kaj so bili vzroki zanje. Leta 1993 je stopil v veljavo Zakon o gozdovih, ki je na področje slovenskega gozdarstva vnesel kar nekaj novosti. Število zaposlenih v gozdarskih podjetjih se je skozi celotno obdobje 1984 - 2005 močno zniževalo. Rezultati analize kažejo na zmanjšanje skrbi za varstvo delavca pred nezgodami pri delu, saj sta glavna kazalnika varstva pri delu (pogostost in resnost nezgod) po letu 1993 bistveno večja kot v predhodnem obdobju. Ukrepi za zmanjšanje števila nezgod bi morali biti usmerjeni v izobraževanje tako mladih kot tudi starejših delavcev, v dopolnilno izobraževanje delodajalcev in vodij del. Pogosteje bi bilo potrebno opozarjatina nevarnosti, ki pretijo pri delu v gozdu, povečati nadzor dela gozdarskih podjetij ter preverjati znanje o varstvu pri delu vseh delavcev.Work accidents in forest are very common. Forestry is one of the most risky activities as well in the world as in Slovenia, where there is never enough safety at work. By comparison of two longer periods (1984 - 1992 and 1993 - 2005) they analysed when, to whom and why accidents occurred, what were their consequences and what caused them. In 1993 Forest Act came into force and brought a lot of novelties. The number of employees in forestry companies has been on decrease throughout the whole period from 1984 to 2005. The results show the decrease in care for protection of worker before accidents. The main indicators of safety at work (frequency, severity) are much higher after 1993 compared to the previous period. Measurements for decreasing the number of accidents should be directed into education of both younger and older workers,additional education of employers and supervisors. Warnings about dangers of working in the forest should be more frequent, the control over forestry companies should be increased and the knowledge of all workers about safety at work should be examined
The influence of wood loading on its changes of acoustical properties
No full textNa šestih izbranih lesnih vrstah (smreka, jesen, bukev, oreh in češnja) smo med navlaževanjem in sušenjem preizkušancev proučevali spremembe modula elastičnosti, frekvenčni odziv in koeficient dušenja. Uporabili smo resonančno metodo z impulzivnim % elastičnim mehanskim vzbujanjem. Ugotovili smo, da je hitrost spremembe modula elastičnosti pri procesu sušenja dvakrat hitrejša kot pri navlaževanju. S povečevanjem vlažnosti se je koeficient dušenja zmanjševal, vendar so zveze statistično nezanesljive. Najmanjše dušenje zvoka smo zasledili pri jesenovini, smrekovini in češnjevini. Sprememba modula elastičnosti je bila v linearni odvisnosti od povprečne vlažnosti medtem, ko je bil odziv dušenja zvoka hitrejši, kar pripisujemo nastalemu vlažnostnemu gradientu.On a six selected species of wood - spruce, ash, oak, beech, walnut and cherry- all test specimens were moistened and dried, we investigated changes in the following modules: fundamental frequency, sound damping and elasticity. The method used was resonance with elastic mechanical excitation. We came to conclusion, that modulus of elasticity in drying process changed two times faster than in the moistening process. With moisture increasing, the sound damping coefficient was decreasing, but changes have not been proved statistically important. Lowest sound damping was detected in spruce, cherry and ash. The change in modulus of elasticity was in linear dependency with average moisture content, while response of sound damping was faster. We concluded, that this is due to the moisture gradient
Analysis of factors affecting the price and quality of guitars
No full textKupci kitar imajo velikokrat težavo, kako oceniti realno vrednost inštrumenta. Zanimalo nas je, kateri so najpomembnejši dejavniki, ki vplivajo na kakovost in ceno kitar. Z anketo smo ugotovili, da so za kupce najpomembnejši: zvok, les trupa in vratu ter nekoliko manj blagovna znamka. S pomočjo AHP metode smo ugotovili, da je najpomembnejši kriterij pri oceni kitare izdelava samega inštrumenta, na samo ceno pa najbolj vpliva ubiralka kitare.The guitar buyers are often faced by dilemma on how to assess the real value of an instrument. Therefore, in my research assignment, I have focused on determining the most influential factors with an impact on quality and price of a guitar. Using the poll method we have come to the conclusion that customer opinions place the highest value on guitar sound and on quality of wood, consisting guitar neck and bodybrand of a guitar is less important to potential customers. The applied AHP method has pointed out the process of guitar making as the key criteria in assessing the guitar qualityguitar fingerboard dictates the height of the price

No full textThe Analysis of a selection of Polish and Slovak unconventional replies based on homonymy, polysemy or rhyme
No full textMagistrsko delo z naslovom Analiza izbranih poljskih in slovaških nekonvencionalnih replik, ki temeljijo na homonimiji, polisemiji ali rimi predstavlja analizo, ki je nastala na podlagi anketnih raziskav o poljskih in slovaških nekonvencionalnih replikah, ki temeljijo na homonimiji, polisemiji ali rimi. Magistrska naloga opisuje žanr nekonvencionalne replike z ozirom na širši kontekst frazeologije in paremiologije ter povzema predhodno ukvarjanje s tem žanrom v slovanskem jezikoslovju. Delo raziskuje delovanje, načine realizacije in produktivnost homonimije, polisemije in rime v nekonvencionalnih replikah v poljskem in slovaškem jeziku. Poleg analize in kategorizacije pojavljanja izbranih jezikovnih sredstev in drugih mehanizmov v nekonvencionalnih replikah naloga predstavi tudi rezultate dveh spletnih anket, s katerima smo preverjali ustaljenost in poznanost določenih enot med poljskimi in slovaškimi govorci. Ob analizi izbranih nekonvencionalnih replik magistrsko delo prikazuje tudi spremembe jezikovnih sredstev in drugih mehanizmov v variantah, pridobljenih z anketama, in potrjuje soobstoj nekaterih enot v različnih oblikah in sorodnih žanrih. V prilogah so zbrane tudi dodatne nekonvencionalne replike, pridobljene s spletnima anketama.The Master\u27s Thesis titled The Analysis of a selection of Polish and Slovak unconventional replies based on homonymy, polysemy or rhyme represents an analysis that is a result of survey conduction. It concerns Polish and Slovak unconventional replies built around homonymy, polysemy or rhyme. The thesis describes the genre of unconventional reply while taking into consideration the wider context of phraseology and paremiology. It summarizes previous dealings with this genre in Slavic linguistics as well. The thesis explores the functioning, ways of realisation and productivity of homonymy, polysemy and rhyme in unconventional replies in the Polish and Slovak languages. Besides the analysis and categorisation of the occurrences of selected linguistic means and other mechanisms in unconventional replies, the thesis also relates the outcome of two online surveys. These were used to investigate the stability and familiarity of certain units among Polish and Slovak speakers. Alongside the analysis of unconventional replies, the thesis also shows the changes in linguistic means and other mechanisms in variants gained through survey conduction. It confirms the coexistence of some units in different forms and related genres. The appendices list the additional unconventional replies obtained through online survey conduction

No full textAn unusual finding of Sepietta oweniana egg clutch at 544 m depth is described within an updating study of the reproductive aspects of the species in Sardinian waters. Egg species identity was determined by genetic analysis and morphological and biometrical data of the eggs, embryos and one newly hatched specimen are reported and discussed. Illustrations of the eggs, spermatophores and spermatangia by photographic material are also included. Data on bathymetric distribution and sexual maturity are reported and compared with data already available for the species in other geographical areas of distributio
An Outline Of The Biology of the Squid Illex Coindetii in the Sicilian Channel (Central Mediterranean)
No full textThe genus Illex is likely to constitute a large portion of the annual world ommastrephid squid catches (Roper et al, 1984), even though specific official statistics are difficult to obtain. The broad-tail short-fin squid Illex coindetii is a widespread species ranging from the western to the eastern Atlantic (Roper et al., 1984) and east through the whole Mediterranean Sea (Mangold & Boletzky, 1987). Usually a by-catch of important fisheries, it is caught mainly by trawlers. Although its economic value is lower than that of other squid species (i.e. Loligo spp.), in the Sicilian Channel Illex coindetii may represent a valuable resource due to its abundance. In Italian waters, the available statistics (Cingolani et al., 1986) report that 2680 tonnes of ommastrephid squid were landed in 1982 (0.5% of the total landed catch). The main component of these was landed in Sicily (2183 tonnes), a consistently large part of which was no doubt Illex coindetii (Ragonese & Jereb, 1992). The catches came mainly from southern Sicilian waters (Sicilian Channel) where one of the major Mediterranean landing places is in Mazara del Vallo. Large trawlers (up to 200 gross tonnage) usually carry out long fishing trips (15–20 d), and Illex coindetii is caught mainly by those targeting Parapenaeus longirostris and Merluccius merluccius (Jereb & Ragonese, 1991)
Anomalies in Sepiolinae hectocotylization
No full textFour cases of anomalies of the copulatory arm in Sepiolinae (Cephalopoda: Sepiolidae) are reported. In one case (Sepietta oweniana), both dorsal arms were modified resulting in double hecocotylization. In another specimen probably of the same species the copulatory apparatus was formed by two fleshy multilobed formations situated on the dorsal and ventral side of the arm base. In one specimen of Rondeletiola minor the copulatory apparatus was inversely positioned on the arm base, and in one Sepiola intermedia specimen the inner free portion of the wrinkled tubercle was markedly enlarged
