No full textThe effect of massage on the subjective feelings of volleyball players
No full textDiplomska naloga obravnava vpliv masaže po treningu na počutje, regeneracijo in športno učinkovitost odbojkarjev. Namen raziskave je bil ugotoviti, ali redna masaža prispeva k hitrejši regeneraciji, boljšemu subjektivnemu počutju in višji športni formi. V raziskavi je sodelovalo več odbojkarjev, razdeljenih v eksperimentalno skupino (ki je redno prejemala masaže) in kontrolno skupino (ki masaž ni prejemala). Podatki so bili zbrani s pomočjo vprašalnika in primerjalne analize.
Rezultati so pokazali, da masaža večini športnikom pomaga pri sprostitvi, hitrejši regeneraciji in manjši mišični napetosti. So pa se med posamezniki kazale razlike, nekateri so masažo doživeli kot zelo pozitivno, pri drugih pa je bil učinek manj izrazit. Kljub temu se masaža kaže kot koristen dodatek trenažnemu procesu.
Raziskava je pokazala, da bi lahko redna masaža v okviru treninga pozitivno vplivala na telesno pripravljenost in psihično počutje športnikov.The thesis examines the effect of post-training massage on the well-being, regeneration, and athletic performance of volleyball players. The purpose of the research was to determine whether regular massage contributes to faster regeneration, better subjective well-being, and higher sports performance. Several volleyball players participated in the study, divided into an experimental group (which received regular massages) and a control group (which did not receive massages). Results were measured by survey questionnaire.
Results showed that massage helps most athletes relax, recover faster, and reduce muscle tension. However, there were differences among individuals, with some experiencing the massage as very positive, while others had a less pronounced effect. Despite this, massage appears to be a useful addition to the training process.
Research has shown that regular massage as part of training can have a positive effect on the physical fitness and mental well-being of athletes

Model zdravja gozdov v Sloveniji
No full textV disertaciji predstavljamo model za ocenjevanje zdravja gozdov v Sloveniji. Model je prostorski z ločljivostjo 1 km * 1 km in ga sestavlja več kot 20.000 celic. Zdravje gozdov ocenjujemo s pomočjo sanitarnega poseka, in sicer v zvezni spremenljivki kot delež lesne zaloge v celici modela. Model smo zgradili s pomočjo metode strojnega učenja M5\u27, ki gradi regresijska odločitvena drevesa. V razvoj modela gozdov Slovenije je bilo vključenih 245 spremenljivk. Model je bil izračunan za tri scenarije podnebnih sprememb in 12desetletnih obdobij, t. j. za obdobje 1981-2100. Z modelom za ocenjevanje zdravja gozdov smo preskušali tri hipoteze: (1) zdravstveno stanje gozdov v Sloveniji se bo zaradi podnebnih sprememb poslabšalo(2) gozdovi s spremenjeno drevesno sestavo so labilnejši, tako v obdobju 1995-2005 kot v podnebnih spremembah(3) zdravje gozda v Sloveniji se bo zaradi podnebnih sprememb v gozdovih s spremenjeno drevesno sestavo bolj poslabšalo kot v gozdovih z ohranjeno drevesno sestavo. Vse tri hipoteze so potrjene. (1) Povečal se bo povprečni delež potencialne sanitarne sečnje v lesni zalogi (povprečno 0,02-0,05 % lesne zaloge na 10 let) in povečala se bo potencialna površina, kjer se lahko pojavi sanitarna sečnja (povprečno 72-111 km2 na 10 let). Hipotezo (2) preskušamo s pomočjo enostavne analize variance, kjer je odvisna spremenljivka povprečni delež sanitarne sečnje v lesni zalogi in faktor stopnja ohranjenosti drevesne sestave. S tveganjem, manjšim od 0,05, trdimo, da obstaja statistično značilna razlika vsaj med dvema povprečnima sanitarnima sečnjama po stopnjah ohranjenosti drevesne sestave tako v obdobju 1995-2005 kot v podnebnih spremembah. Hipotezo (3) smo preskušali z intervalomzaupanja za razliko povprečij in t-preskusom. V gozdovih s spremenjeno drevesno sestavo bo povprečni sanitarni posek pri 95 % zaupanju za2,05-3,38 % lesne zaloge večji kot v gozdovih z ohranjeno drevesno sestavo, če privzamemo Smolejevo klasifikacijo ohranjenosti drevesne sestave. Rezultat disertacije so tudi modeli za ocenjevanje potencialne sanitarne sečnje zaradi žuželk, žleda, dela v gozdu in drugih vzrokov (po klasifikaciji sanitarne sečnje Zavoda za gozdove Slovenije), katerih projekcije so bile izračunane za tri scenarije podnebnih sprememb do konca 21. stoletja. Potencialnih sanitarnih sečenj zaradi žuželk bo predvidoma več, zaradi žleda in dela v gozdu manj, in zaradi drugih vzrokov drastično več.In this dissertation, a model for assessing forest health in Slovenia is presented. The model is spatial with a resolution of 1 km * 1 km, consisting of over 20,000 cells. Forest health is assessed with the help of sanitary felling as a dependant variable of the wood stock portion in a model cell. Themodel was built with the M5\u27 machine learning method that builds regressiontrees. Altogether, 245 variables were included at the model development. The model was computed for three climate change scenarios and 12 ten-year periods, i.e. for the period 1981-2100. Three hypotheses were tested with the model: (1) Forest health conditions in Slovenia will deteriorate because of climate change impacts(2) Forests with altered tree species composition are more labile, as in the period 1995-2005 and in future climate change(3) Forest health in Slovenia will deteriorate more in forests with altered tree species composition than in forests with preserved tree species composition because of climate change impacts on forests. All three hypotheseshave been proven to be true. (1) The average portion of potential sanitary felling at wood stock will increase (in average 0.02-0.05 % of wood stock per ten years) and the potential area sensitive for sanitary felling will increase (in average 72-111 km2 per ten years). Hypothesis (2) is tested with analysis of variance, where a dependant variable is the average portion of sanitary felling at wood stock and a factor is the index of species composition alternation. We affirm that there is a statistically significant difference between the mean sanitary felling from one level of the species composition alternation index to another at a 95 % confidence level as in period 1995-2005 and in climate change. Hypotheis (3) is tested with confidence interval for the difference between the means and t-test. The mean sanitary felling in the forests with altered tree species composition is likely to be greater for 2.05-3.38 % of wood stock at 95 % confidence than in the forests with preserved tree species composition, when Smolej\u27s classification of tree species composition is taken. The results of the dissertation are also models for assessing potential sanitary felling because of insects, freezing rain, work in forest and other causes (after Slovenia Forest Service\u27s classification of sanitary felling). For these models, the projections were calculated for three climate change scenarios until the end of 21st century. There will be probably more sanitary felling because of insects, because of freezing rain and work in forests there will be less sanitary felling, and because of other causes, there will be a drastic increase in sanitary felling

REVERSIBLY STABLE THIOPOLYPLEXES FOR INTRACELLULAR DELIVERY OF GENES
No full textNovel polyaspartamide non-viral carriers for gene therapy were synthesized by introducing, on the same polymer backbone, positively charged
groups, for electrostatic interactions with DNA, and thiol groups for the formation of disulfide bridges between polymer chains. The introduction
of thiols was aimed to have a vector with low redox potential sensitivity: disulfide crosslinking in fact, being stable in extracellular environment,
allowed either to have stable complexes in plasma, that can protect DNA from metabolism, or to be reduced inside the cell, where the excess of
glutathion in reduced form maintains a low redox potential. The consequent destabilization of the complex after disulfide cleavage can release
DNA selectively inside the cells.
α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide (PHEA) was used as starting polymer being a highly water-soluble synthetic polymer, already
proposed with success as therapeutic carrier by our group. In this study, PHEA was firstly functionalised with ethylendiamine, obtaining a well
defined copolymer with pendant primary amine groups (PHEA-EDA), to which N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP) and 3-
(carboxypropyl)trimethyl-ammonium chloride (CPTA) were linked in two subsequent steps, allowing the introduction of thiol and cationic groups
respectively. Finally DTT treatment lead to the final PHEA-EDA-SH-CPTA thiopolycation, named PESC.
The present work describes the synthesis and characterization of the thiopolycation PESC. 1H NMR spectroscopy detected the derivatization
molar degrees in SPDP and CPTA; the formation of DNA complexes (thiopolyplexes), their stability in the presence of polyanions and the ability
to release DNA under reductive conditions were studied by agarose gel electrophoresis. DNase II degradation study was carried out to detect the
ability of thiopolyplex to stabilize DNA towards enzymatic metabolism. Thiopolyplexes were then characterized by Dynamic Light Scattering
(DLS) and Zeta Potential analysis. Finally, in vitro toxicity profile (MTT) and gene transfer efficiency (Luciferase assay) were carried out to
evaluate thiopolyplex biocompatibility, safety and efficacy to be used as gene delivery system.

First Report of Diplodia fraxini and Diplodia subglobosa Causing Canker and Dieback of Fraxinus excelsior in Slovenia
No full textIn recent decades the vitality and productivity of European ash trees in Slovenia have been reduced by the onset of canker and dieback disease symptoms on young and old trees, identified primarily as ash dieback caused by Hymenoscyphus fraxineus. Given the limited information available about the etiology of this emerging disease, a study was carried out to isolate, identify, and characterize the fungal species involved in the observed ash symptoms. Field surveys were conducted in five forest sites where 50 symptomatic branch samples were collected. All samples were inspected and used for fungal isolation. Based on morphology, colony appearance, and DNA sequence data of the internal transcribed spacer region, 125 fungal colonies belonging to five species were isolated and identified. Only a few symptomatic ash samples yielded colonies of H. fraxineus, whereas Botryosphaeriaceae species were isolated with a high frequency, with Diplodia fraxini as the dominant species. A pathogenicity test proved that all isolated species were pathogenic on European ash, causing bark lesions and wood discoloration. All Botryosphaeriaceae species isolated in this study are reported for the first time on European ash in Slovenia

No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
NOVEL BIOCOMPATIBLE CATIONIC COPOLYMERS BASED ON POLYASPARTHYLHYDRAZIDE BEING POTENT AS GENE VECTOR ON TUMOR CELLS
No full textIntroduction. The reaction between !,"-poly(aspartylhydrazide) (PAHy), a water soluble synthetic
polymer and 3-(carboxypropyl)trimethyl-ammonium chloride (CPTACl) produced copolymers bearing
permanent positive charges (PAHy–CPTA) with molecular weight of 10 kDa and PAHy–CPTA
copolymers differing in positive charge amount (18–58%) were chosen for biological investigations.
Materials and methods. Biophysical properties of DNA/PAHy–CPTA polyplexes were evaluated in
terms of DNA condensation, zeta potential and size distribution. Cytotoxicity studies on Neuro2A
murine neuroblastoma cells evidenced absence of toxicity of these copolymers up to 300 2g/ml unlike
linear polyethylenimine (LPEI) that was highly toxic already at 20 2g/ml.
Results and Discussion. PAHy–CPTA copolymers did not induce any erythrocyte aggregation up to
1 mg/ml. Cellular interaction studies of PAHy–CPTA polyplexes evidenced a faster binding of these
polyplexes with cells compared to DNA/LPEI polyplexes. The in vitro transfection ability of PAHy–
CPTA polyplexes was strongly affected by experimental conditions reaching about 10% of the
transfection efficiency of optimized LPEI polyplexes.
Conclusions. Finally, in vivo application studies confirmed the biocompatibility of PAHy–CPTA
copolymers. With LPEI, clear signs of microvesicular fatty liver were observed and with LPEI
polyplexes significant weight loss. In strong contrast, PAHy–CPTA did not induce histopathological
changes or weight loss
