Organizational culture in logistics companies and its impact on employee satisfaction
The aim of this research was to analyze organizational culture and the impact of different types of organizational cultures on employee satisfaction in the Slovenian logistics sector. Logistics is a service-oriented sector and therefore the impact of employee satisfaction on the quality of logistics service is even more important than in general. For the purpose of research, we conducted a quantitative survey, which combined the OCAI survey for the determination of organizational culture and the survey of employee satisfaction. The research results showed that organizational culture in Slovenian logistics sector has an impact on employee satisfaction. We can also confirm that type of organizational culture influences the satisfaction of employees. The clan and hierarchical type of organizational culture are dominant in Slovenian logistics sector. Employees prefer the clan culture which, accordingly, also leads to more employee satisfaction. It can be argued that employees in Slovenian logistics sector are the most dissatisfied with the type of market culture
Strateška lega zgornje Pivke
Zgornja Pivka je že večkrat v zgodovini odigrala pomembno vlogo prav zaradi svoje strateške lege. Nazadnje se je to pokazalo po prvi svetovni vojni, ko je z uveljavitvijo Rapallske pogodbe pripadla Italiji in tako postala mejno ozemlje. Prek meje se je vzpostavil kontrabant. Čez Pivško kotlino je potekala druga linija Alpskega zidu, mogočnega obrambnega sistema, ki naj bi branil vzhodno mejo pred Jugoslavijo. Naravni prehod v smeri sever-jug, dobra preglednost nad kotlino ter dobri pogoji za oskrbo vojaških enot so bili glavni razlogi za izgradnjo utrdb na Primožu, kjer je bil hkrati komandni center za okoliške bunkerje. Za vojaške potrebe so zgradili vodne zbiralnike, ceste, mostove, smodnišnico, letališče, regulirali strugo reke Pivke in pogozdili burji izpostavljene predele. Vojska je trenirala na Petelinjskem in Palškem jezeru. Tu sta bila vojaška poligona že iz časa Avstro-Ogrske. Na jezerih je izvajala vojaške manevre tudi Jugoslovanska ljudska armada, ki je za razliko od italijanske vojske povzročila veliko večjo škodo. Dno Palškega jezera so 1990. leta sanirali in lastnikom zemljišč izplačali odškodnino, medtem ko najdemo na Petelinjskem jezeru še vedno luknje od granat, topovska gnezda in strelski jarek. Its strategic position has given Upper Pivka (Zgornja Pivka) an important role in history on several occasions. The last of these occurred after the implementation of the Rapallo Treaty at the end of the First World War, when the area was annexed to Italy and turned into borderland. Across the border the ‘Kontrabant’ developed. Through the Pivka Basin (Pivška kotlina) ran the second line of the Alpine Wall, which was a mighty defence system build to protect Italy’s eastern border with Yugoslavia. The natural north-east passage, a good view of the valley, and good conditions for supplying military units were the main reasons for building fortifications on the Primož hill. The command centre for the nearby bunkers was also located there. For military purposes, water reservoirs, roads, bridges, a powder magazine, and an airfield were built; the bed of the Pivka river was regulated, and the parts most exposed to strong winds (“burja”) were forested. Lakes Petelinjsko jezero and Palško jezero were used as training fields by the army. The two military fields had already been in service in Austro-Hungarian times. The Yugoslav People’s Army also used the lakes for its manoeuvres and did much more damage to them than the Italian army had done previously. The bottom of Palško jezero was reconstructed in 1990, and the owners were compensated. On Petelinjsko jezero, however, bomb craters, gunnests, and a trench can still be seen.
Trapping mechanisms of carnivorous plants
Iako nam se biljke na prvi pogled čine vrlo statičnima, one se zapravo mogu gibati, a neka od tih gibanja su vrlo brza. Primjer takvih brzih gibanja je zatvaranje stupica kod karnivornih biljaka rodova Aldrovanda, Utricularia i Dionaea. Mehanizmi tih gibanja su složeni. Karnivorne su biljke te mehanizme razvile zbog prilagodbe na okolišne uvjete i manjak potrebnih nutrijenata. Kod venerine muholovke u mehanizam zatvaranja uključene su aktivna biokemijska komponenta i pasivna elastična komponenta, međutim nijedna nije u potpunosti objašnjena. Još uvijek nije razjašnjen točan prijenos K+ iona preko membrana stanica kao ni način na koji venerina muholovka „pamti“ dva uzastopna podražaja koji se dese u vremenskom razmaku od 20 s. Mjehurasta vodena stupica ima mehanizam zatvaranja u koji je prilikom savijanja uključeno samo središnje rebro. Po tome se najviše razlikuje od mehanizma zatvaranja stupice kod venerine muholovke. Zašto se razlikuju, iako potječu od zajedničkog terestičkog pretka, još uvijek nije u potpunosti jasno. Kod vrsta roda Utricularia plijen biva uhvaćen usisavanjem. Unutar mjehurate stupice nađeni su različiti
mikroorganizmi, međutim ne zna se koji su mutualistički, a koji biljka hvata i razgrađuje da bi iz njih uzela potrebne minerale. Nije razjašnjeno ni zašto dolazi do povremenog zatvaranja stupice bez ikakvog podražaja. Sudeći po svim pitanjima koja ostaju neodgovorena u vezi različitih mehanizama zatvaranja stupica, to područje biologije ostaje otvoreno za mnoga istraživanja.When observing plants, they seem relatively immobile, but if we carefully watch them, it is clear that plants do provide movements, and sometimes even rapid ones. Trapping mechanisms of carnivourus plants in the genera Aldrovanda, Utricularia and Dionaea, are some of examples. These mechanisms are very complex, and are developed as an adaption to environmental conditions and lack of nutrients. Trapping mechanisms of the Venus flytrap include active biochemical component and passive elastic component, but none of them are completely understood. Exact transport of K+ ions through the cell wall, and the way Venus flytrap „memoryizes“ two stimulus within 20 s, are not clear enough. The waterwheel plant deforms only her midrib during closure. That is the main diference between trapping mechanism of the Venus flytrap. Even though they originate from the same ancestor, it is still not fully understood why their mechanisms are different. All species of the genus Utricularia have suction traps. In their traps there are various microorganisms but it is not understood yet which of them are microorganisms living as commensals and which are prey used for absorption of mineral nutrients. Spontaneous firings without any apparent cause are also not yet fully clear. Many questions regarding the different mechanisms of closing traps remain unanswered leaving this field of biology with wide range of possible research

The effect of lead on photosynthetic efficiency and pigments in the lichens Flavoparmelia caperata (L.) Hale and Evernia prunastri (L.) Hale
Lišajevi su kozmopolitski organizmi i izvrsni bioindikatori zagađenja zraka. Sposobni su
bioakumulirati teške metale, a toksičnost metala ovisi o kemijskim i fizikalnim faktorima. Cilj
istraživanja je bio odrediti osjetljivost vrsta Evernia prunastri (L.) Ach i Flavoparmelia
caperata (L.) Hale na izlaganje olovu te utvrditi kako pH vrijednost otopine (4 i 6) i vrsta
otopine (destilirana voda ili Hoaglandova otopina), modificiraju učinak olova nakon 1., 7. i
14. dana. U obje vrste tretman olovom je snizio QYmax (maksimalni kvantni prinos
fotosustava II) nakon 1., 7. i 14. dana, što ukazuje na smanjenu učinkovitost fotosinteze. U
vrste E. prunastri Hoaglandova otopina smanjila je negativan učinak olova osobito pri pH
vrijednosti 6, dok je u vrste F. caperata Hoaglandova otopina smanjila negativan učinak
olova tek nakon 14. dana. U obje vrste lišajeva tretman olovom je uglavnom snizio
koncentraciju klorofila a i klorofila b te karotenoida tek nakon 14 dana tretmana. Niži
koeficijent feofitinizacije ukazuje na degradaciju klorofila a uslijed tretmana olovom.
Hoglandova otopina smanjila je negativan učinak olova na pigmente ali u vrste E. prunastri to
se očitovalo kod pH vrijednosti 6, a u vrste F. caperata pri pH vrijednosti 4. U obje vrste lišaja
tretman olovom je povisio razinu lipidnih peroksida osobito pri pH vrijednosti 6.
Hoaglandova otopina pH vrijednosti 6 smanjila je negativan učinak olova na oštećenje
membrana. Na temelju rezultata može se zaključiti da su obje vrste lišaja osjetljive na
tretman olovom osobito pri pH vrijednosti 6 što je posljedica bolje dostupnosti olova pri toj
pH vrijednosti. U obje vrste prisutnost iona iz Hoaglandove otopine smanjila je negativan
učinak olova ali je efikasnost ovisila o pH vrijednosti otopine koja je bila različita za svaku
vrstu.Lichens are cosmopolitan organisms and great bioindicators of air pollution. They
bioaccumulate heavy metals whose toxicity depends on chemical and physical factors. Aim
of this research was to determine sensitivity of Evernia prunastri (L) Ach and Flavoparmelia
caperata (L) Hale to lead exposure and to determine if changes in pH value (4 or 6) and
solution composition (Hoaglnd solution or destilled water) modulate lead toxicity after 1., 7.
and 14. days of exposure. Both species showed lower QYmax (the largest light quantum
efficiency of photosystem II) when tretated with lead after 1., 7. and 14. days of exposure
which indicates decrease in photosynthetic efficiency. Hoagland solution reduced negative
effect of lead especially at pH value 6 in E. prunastri, while in F. caperata it reduced negative
effect of lead only after 14. days of exposure. In both species lead treatment mainly
decreased chlorophyll a, chlorophyll b and carotenoid concentrations only after 14. days of
treatment. Decreased phaeophytinization coefficient indicates chlorophyll a degradation
due to lead treatment. Hoagland solution decreased negative effect of lead on pigments, in
E. prunastri at pH value 6 and in F. caperata at pH value 4. In both species lead tretment
increased concentration of lipid peroxides especially at pH value 6. Hoagland solution at pH
value 6 decreased negative effect of lead on membrane damage. These results confirmed
sensitivity of both lichen species to lead treatment, most notably at pH value 6 when lead
availability is the highest. In both species availability od ions from Hoagland solution
decreased negative effect od lead, but it depended on the pH value of solution and was
different for each lichen species
