Authors: OREŠNIK Andrej , LAVRENČIČ Andrej , STOPAR Jože 
Published: December 2023

V letu 1997 smo na različnih parcelah iste površine v štirih košnjah in v različnih razvojnih fazah rastlin zbrali po 10 vzorcev črne detelje (Trifolium pratense) in mnogocvetne ljuljke (Lolium multiflorum) ter po 8 vzorcev mačjega repa (Phleum pratense), trpežne ljuljke (Lolium perenne), travniške bilnice (Festuca pratensis), rdeče bilnice (Festuca rubra) in pasje trave (Dactylis glomerata). Največjo povprečno vsebnost mangana v suhi snovi smo ugotovili v vzorcih pasje trave (215,3 ± 54,9 mg kg-1 SS) in v vzorcih rdeče bilnice (55,7 ± 7,8 mg kg-1 SS). Druge trave in črna detelja so vsebovale statistično značilno manj mangana v suhi snovi (od 33,1 mg do 42,0 mg kg-1 SS). Pri travah z manjšo vsebnostjo mangana in pri črni detelji je bila ob prvi košnji vsebnost mangana največja v fazi bilčenja (25,2 mg do 61,6 mg kg-1 SS) in najmanjša v fazi cvetenja (16,6 mg do 47,8 mg kg-1 SS). Pri pasji travi pa je vsebnost mangana v suhi snovi z zorenjem rastline v prvi košnji naraščala (od 145,5 mg na 179,5 mg kg-1 SS). Najmanjša povprečna koncentracija mangana je bila pri vseh travah in pri črni detelji v vzorcih prve košnje (od 21,0 mg do 53,0 mg kg-1 SS) in največja jeseni ob četrti košnji (od 42,2 mg do 68,7 mg kg-1 SS), pri pasji travi pa je bila ob prvi košnji 160 mg, ob drugi 272,0 mg in se je v tretji in četrti košnji zmanjšala na 209,6 mg oziroma 215,4 mg kg-1 SS.

Authors: ACCETTO Tomaž , AVGUŠTIN Gorazd 
Published: December 2023

Twenty-nine strains belonging to four species of the anaerobic bacterial genus Prevotella were tested for deoxyribonuclease activity against the nonmethylated l phage DNA and circular plasmid pBR322 DNA. The rate of DNA degradation when comparing different species and even strains within the tested species showed large variation. The strains of the species P. brevis and P.bryantii (with exception of the strain TC1-1) all exhibit high activity and completely degraded l DNA after 30 seconds. No DNase activity could however be detected with 14 of the 29 tested strains. The survey of the DNase activities confirmed the validity of the recent reclassification of rumen bacteria from the genus Prevotella. A simple method allowing the screening of DNase activities of anaerobic rumen microorganisms on agar plates is described too.

Published: December 2023

Z metodami molekularne biologije smo pripravili odseka DNA seva LF221 z zapisom za acidocin LF221 A oziroma acidocin LF221B. Na 0,9 kb dolgem odseku BamHI/HindIII, ki ima zapis za acidocin LF221 A, smo ugotovili prisotnost dveh bralnih okvirjev (ORF) ter del tretjega. Za OrfA2 se je izkazalo, da nosi zapis za strukturni gen za acidocin LF221 A (Acd221A), medtem ko OrfA3 nosi zapis za peptid, dolg 90 aminokislinskih ostankov, ki ima zelo verjetno vlogo proteina imunosti (Aci221A). OrfA1, za katerega je trenutno znanih 37 aminokislin, pa je najverjetneje komplementarni peptid (Acd221α) acidocina LF221 A. Z analizo 1,8 kb dolgega odseka EcoRI/HindIII (ima zapis za acidocin LF221 B) smo potrdili prisotnost štirih zaključenih ORF in enega nepopolnega. OrfB3, OrfB4 in OrfB5, ki nosijo zapis za komplementarni peptid (Acd221β) acidocina LF221 B, aktivni peptid (Acd221B) acidocina LF221 B oziroma protein imunosti (Aci221B), se nahajajo na istem operonu. Iz rezultatov analiz genskega zapisa acidocinov in sosednjih genov smo zaključili, da gre za dva različna, dvo-peptidna bakteriocina seva LF221.
Kalivost oluščenega in obrušenega semena pire (Triticum aestivum L. var. spelta) v primerjavi s kalivostjo plevnatega semena
Authors: KOCJAN AČKO Darja 
Published: December 2023

Kmetje, ki sejejo oluščeno ali oluščeno in obrušeno seme pire (Triticum aestivum L. var. spelta) ugotavljajo slab vznik, zapleveljenost redkega posevka, pridelek pa je manjši od pričakovanega. V postopku luščenja plevnatega semena in brušenja oluščenega semena pire lahko nastanejo poškodbe, zaradi katerih seme ne kali ali le deloma kali. Da bi ugotovili razlike med različno obdelanimi semeni in da bodo kmetje, ki ne kupijo deklariranega semena, posejali seme pire s čim večjo kalivostjo, je bila z laboratorijskimi testi kalivosti po metodiki ISTA preučena kalivost plevnatega, oluščenega in obrušenega semena pire sorte 'Ostro' iz pridelka na isti njivi v letih 2002 in 2003 pri štirih pridelovalcih. Luščenjenje in brušenje je potekalo na različnih aparatih v lasti pridelovalcev ali služnostno drugje. V primerjavi s povprečno 96,4-odstotno kalivostjo plevnatega semena pire pri vseh pridelovalcih v obeh letih, je bila povprečna kalivost oluščenega semena 80,5-odstotna, kalivost obrušenega semena pa le 37,8-odstotna. Na podlagi rezultatov kalivosti je za setev najbolj ustrezno plevnato seme pire. Oluščeno seme posejano z žitno sejalnico ima prednost pred plevnatim semenom le pri dovolj veliki kalivosti. Med štirimi vzorci oluščenega semena je bila obe leti preučevanja kalivost nad 90 % samo pri vzorcu od enega pridelovalca. Obrušeno seme pire je zaradi premajhne kalivosti neprimerno ne le za setev, ampak tudi za pripravo kalčkov, na kar velja še posebej opozoriti uporabnike. V kolikor semena za setev ali kalčkov ne spremlja semenska deklaracija, naj uporabniki izvedejo test kalivosti po metodi med papirjem (BP), ki ima zaradi enostavne izvedbe prednost pred drugimi metodami, s katerimi se ugotavlja laboratorijska kalivost semena.
Influence of foliar-applied phosphorus and potassium on photosynthesis and transpiration of ‘Golden Delicious’ apple leaves (Malus domestica Borkh.)
Authors: VEBERIČ Robert , VODNIK Dominik , ŠTAMPAR Franci 
Published: December 2023

The influence of foliar-applied phosphorus (P) and potassium (K) on leaf photosynthesis, transpiration and water use efficiency during the season was studied in Malus domestica ‘Golden Delicious’. The research was carried out on 14-year-old trees on M9 rootstocks. Trees were either sprayed with PK (Hascon M 10 AD), P (Radicon) or K fertiliser (Krad) or left unsprayed (control). PK spraying improved leaf potassium content and postponed the seasonal decrease in leaf potassium concentration. In other treatments, on the other hand, fertilizers were less effective in terms of leaf nutrient concentration enhancement. In general P, and to a lesser extent PK, spraying resulted in reduced leaf photosynthesis and transpiration to the K and control treatments. High leaf photosynthetic and transpiration rates were measured in the control. Trees sprayed with PK showed the highest water use efficiency during the summer period, which could be a benefit in response to water stress, frequently experienced under given climate.
Prediction of chemical composition and energy value of hay by near-infrared reflectance spectroscopy (NIRS)
Authors: ŽNIDARŠIČ Tomaž , VERBIČ Jože , BABNIK Drago 
Published: December 2023

One hundred and fifty-eight hay samples with known chemical composition and in vitro determined concentration of net energy for lactation (NEL) were scanned over the wavelength range from 1100 to 2500 nm at 8 nm intervals. Calibration equations for the prediction of dry matter (DM), crude protein (CP), crude fibre (CF), crude fat, ash and NEL were developed by the use of principal component analysis. NIRS demonstrated high predictive ability for CP (R2 = 0.98), CF (R2 = 0.95) and ash (R2 = 0.94). Only moderate accuracy was characteristic for DM (0.87) and crude fat (R2 = 0.75). With exception of ash deviations from reference methods are comparable to those which are expected by the use of the same reference methods in different laboratories. NIRS has a high ability to predict in vitro assessed NEL concentration (R2 = 0.89). More than 95% of samples lied within acceptable limits of ± 0.3 MJ NEL kg–1 dry matter (DM). Despite suboptimal sample distribution, i.e. small number of samples in classes below 4.4 and above 5.6 MJ NEL kg–1 DM, the deviations of NIRS predicted values from reference values were not related to concentration of NEL. It was concluded that NIRS is rapid and reliable technique for determination of chemical composition and energy value of hay.
Navidezna prebavljivost surovih beljakovin in surovih maščob pri linijah miši selekcioniranih na višji oziroma nižji odstotek telesnih maščob
Authors: TREBUŠAK Tina , PIRMAN Tatjana , HORVAT Simon 
Published: December 2023

Debelost in naraščanje indeksa telesne mase (ITM) predstavljata v današnjem času velik zdravstveni problem pri ljudeh, prekomerna zamaščenost pa je prav tako nezaželena pri reji domačih živali, saj poslabšuje gospodarnost prireje. V naši raziskavi smo preučevali vpliv debelosti laboratorijskih miši na navidezno prebavljivost surovih beljakovin in surovih maščob zaužite krme. V dveh prebavljivostnih poskusih smo uporabili dve selekcijski liniji miši, linijo F (višji odstotek telesnega maščevja) in L (nižji odstotek telesnega maščevja). V prvem poskusu smo uporabili 21 samcev obeh linij (11 linije F in 10 linije L), starih od 9,0 do 18,6 tednov, v drugem pa 23 samcev (11 linije F in 12 linije L), starih od 9,6 do 11,0 tednov. V času poskusa (5 zaporednih dni) smo živali dnevno tehtali, merili količino zaužite krme in zbirali blato. Po postopkih weendske analize smo v vzorcih določili vsebnost surovih beljakovin in surovih maščob v krmi in blatu. Rezultati so pokazali, da med linijama F in L obstajajo statistično značilne razlike v navidezni prebavljivosti surovih beljakovin in surovih maščob. Pri zauživanju krme ni bilo statistično značilnih razlik med linijama, so se pa pokazale statistično značilne razlike pri zaužiti krmi na g telesne mase. Linija L je bolje prebavila tako surove beljakovine (79,6 %), kot tudi surove maščobe (91,8 %), v primerjavi z linijo F, pri kateri je bila navidezna prebavljivost v povprečju 77,1 % oziroma 87,0 % za surove beljakovine in surove maščobe. Glede na dobljene rezultate sklepamo, da z razlikami v navidezni prebavljivosti beljakovin in maščob krme ne moremo razložiti velikih fenotipskih razlik med linijama.
Nekateri pristopi za izkoriščanje heteroze pri navadni pšenici (Triticum aestivum L.)
Authors: TITAN Primož , MEGLIČ Vladimir 
Published: December 2023

Heterozo najpogosteje povezujemo s superiornostjo prve filialne generacije nad parentalno. Z gospodarskega stališča pa je še posebej pomembno, da se lahko ta superiornost izraža kot višji produktivni potencial sorte. Zaradi počasne rasti višine povprečnega pridelka zrnja navadne pšenice (Triticum aestivum L.) na svetovni in državni ravni, je uporaba hibridov pri tej gospodarsko pomembni poljščini vedno bolj pomembna. Pogoj za pridelavo hibridnega semena je tujeprašnost, ki jo je pri navadni pšenici možno doseči z indukcijo moške sterilnosti. V preteklosti so bili za indukcijo moške sterilnosti v materni komponenti hibridne sorte predlagani pristopi, kot je uporaba moško sterilne citoplazme (CMS sistem) prenesene iz Triticum timopheevi Zhuk.. Zaradi svoje kompleksnosti se pristopi na genetski osnovi v praksi niso nikoli dovolj uveljavili. Danes omogočajo sredstva za kemično hibridizacijo razvoj hibridnih sort, ki presegajo pridelek zrnja standardnih linijskih sort tudi za več kot dvajset odstotkov. Alternativo kemični indukciji moške sterilnosti predstavljajo transgeni pristopi. Pridelava hibridnega semena navadne pšenice je tehnološko zahteven postopek o gospodarski upravičenosti katerega odločajo raven heteroze, višina pridelka hibridnega semena na enoto površine in prodajna cena pšenice.

Published: December 2023

Zbirka fižola, ki jo v okviru Slovenske rastlinske genske banke hranimo na Kmetijskem inštitutu Slovenije, obsega 1035 genskih virov, ki so bili v zadnjih 25ih letih zbrani na območju Slovenije. V zbirki imamo tudi 61 genskih virov, ki smo jih pridobili v okviru sodelovanja v mednarodnih ekspedicijah v tujini ter 39 virov, ki smo jih za potrebe raziskovalnega dela pridobili iz drugih genskih bank v Evropi in svetu. Večina slovenskih virov predstavlja navadni fižol (Phaseolus vulgaris L.), manjši del pa je laškega, turškega fižola (P. coccineus L.). Za vse shranjene vzorce imamo na voljo osnovne podatke. Vsako leto določeno število vzorcev razmnožimo in naredimo osnovno karakterizacijo. Del zbirke smo podrobneje ovrednotili z uporabo morfoloških, biokemijskih in molekulskih markerjev. Rezultati so pokazali, da se je v več stoletjih pridelovanja v Sloveniji oblikovala raznolika dednina, ki jo je vredno ohraniti. Obsežneje smo ovrednotili odpornost na glivo Colletotrichum lindemuthianum, ki povzroča fižolov ožig. Vzorce, shranjene v genski banki, uporabljamo za različne raziskave, med katerimi prevladujejo raziskave sušnega stresa. Prav tako pa jo uporabljamo v žlahtniteljskem procesu za žlahtnjenje novih sort ter za reintrodukcijo starih sort.
Zbirka samoniklih virov rukole v Slovenski rastlinski genski banki
Authors: UGRINOVIĆ Kristina , ŠKOF Mojca 
Published: December 2023

Med vrstami, ki jim s skupnim imenom pravimo rukola, v Sloveniji samoniklo rastejo le tri vrste iz rodu dvoredca (Diplotaxis tenuifolia, Diplotaxis muralis in Diplotaxis viminea), medtem ko vrste iz rodu rukvice (Eruca) v naravi niso prisotne. V Genski banki kmetijskih rastlin pri Kmetijskem inštitutu Slovenije je zbranih in shranjenih 19 avtohtonih virov iz različnih predelov Slovenije. Pri vseh smo ocenili nekatere morfološke in agronomske lastnosti. Pri večini virov so prisotni različni tipi rastlin, nekateri viri pa so tudi mešanica različnih vrst. Razmnoževanje v izolaciji se je pokazalo za težavno in ne prav uspešno. Pri različnih virih je bila oploditev v izolaciji različno dobra, iz česar lahko sklepamo, da imajo različno samoinkompatibilnost. V prihodnje bi bilo zbirko potrebno dopolniti z viri iz še nepregledanih predelov Slovenije, vire še podrobneje oceniti in proučiti razmnoževanje v izolaciji.
Investigation on voltage stability evaluation indicators and algorithms for power systems based on neural network algorithms
Authors: Cai Xi , Quan Chaoyang , Chen Yuanyuan 
Published: December 2023

Abstract
In order to avoid the occurrence of unstable phenomena in the Power Grid (PG), it is necessary to have a thorough understanding of the current operating status of the PG. Research on voltage stability evaluation indicators and algorithms in the power system can assist power system operators in making effective decisions. In this paper, an improved continuous power flow scheme based on Lagrange quadratic interpolation was adopted. Secant method and Lagrange quadratic interpolation method were used for prediction comparison, and Newton method was used to correct the predicted results. This article utilized an online voltage safety assessment and warning model to ensure the safe operation of the PG and reduce the occurrence of faults. To ensure the integrity and accuracy of network dynamic information, a least squares fitting method based on orthogonal functions was adopted to improve the fitting accuracy without increasing communication volume. As the step size increases from 2 to 3, the number of power flow solutions decreased and the solution time increased. The effectiveness of the voltage stability evaluation algorithm in this paper was verified through simulation of two node systems: New England 39 and IEEE118.

Paracompactness and Open Relations
Authors: Gutev Valentin 
Published: December 2023

ABSTRACT
The countably paracompact normal spaces were characterised by Dowker and Katětov in terms of an insertion property. Dowker also described them by normality of their product with the closed unit interval. Michael used the Dowker-Katětov insertion property to motivate his selection characterisation of these spaces. Morita extended in a natural way Dowker’s product characterisation to all τ-paracompact normal spaces. In this paper, we look at these results from the point of view of open relations. Insertions and selections are equivalent for such relations. Furthermore, we obtain a natural characterisation of τ-paracompact normal spaces in terms of selections for convex-valued open relations. Based on this, we give simple alternative proofs of the above mentioned results. Other applications are obtained as well.

Published: December 2023

Water-borne acrylic resin has attracted much attention thanks to its environmetally friendly, high weather stability, good mechanical properties, high toughness. It is widely used in coatings, ships, bridges, locomotives, etc. In this work, the effect of ZrO2 nanoparticles content which were modified with (3-glycidyloxypropyl)triethoxysilane (GPTS) on the weather resistance of the acrylic emulsion coatings was tested and discussed. The change in functional groups, carbonyl index value, gloss, weight and morphology of the coatings before and after accelerated weathering test was investigated. The obtained results showed that the GPTS modified ZrO2 nanoparticle content had a significant effect on the characteristics of acrylic emulsion coatings. The 2 wt.% content of GPTS modified ZrO2 nanoparticles exhibited a highest efficiency in improvement of weather resistance of acrylic emulsion coatings. This result indicated that acrylic emulsion coating filled by the GPTS modified ZrO2 nanoparticles is potential for outdoor applications.

Published: December 2023

Aim. To demonstrate the efficacy of minimally invasive surgery for bile duct injuries.Materials and methods. The results of combined minimally invasive treatment of 52 patients with fresh bile duct injuries from 2006 to 2023 were analyzed. Bile duct injuries diagnosed within 1–10 days after the operation were referred to as “fresh”. Intraoperative detection of bile duct injury was the criterion of exclusion from the analysis. In 80.8% of observations, combined minimally invasive interventions were performed in the form of percutaneous operations under ultrasound and radiography control. In 19.2% of observations, antegrade percutaneous and retrograde endoscopic access was used.Results. The algorithm for conducting minimally invasive procedures for bile duct injuries and strictures should be selected depending on the terms of injury and the character of injury and complications. In the majority of fresh bile duct injuries, a two-stage algorithm of duct patency restoration was applied. This prevented additional complications and allowed the patient to be prepared for stent biliary drainage after analyzing the primary data of fistula cholangiography. In all observations, minimally invasive procedures of bile duct patency restoration were completed with stent biliary drainage. Complications were noted in eight patients (15.4%).Conclusion. In fresh bile duct injuries, combined minimally invasive methods are an effective alternative to conventional reconstructive surgeries.

Aim. To evaluate the immediate results of robot-assisted liver resections in locally advanced intrahepatic cholangiocarcinoma.Materials and methods. The research methodology involved the analysis of intraoperative and direct results of robotassisted liver resections from 2015 to June 2023.Results. Total of 89 patients with intrahepatic cholangiocarcinoma underwent surgery. Open liver resection was performed in 59 cases (66.3%), laparoscopic resection – in 22 cases (24.7%), robot-assisted resection – in 8 cases (8.9%). The share of massive liver resections accounted for 83%. The average duration of robot-assisted liver resection amounted to 545 (327–640) minutes, blood loss volume – 300 (100–750) ml, number of resected lymph nodes – 7 (5–11), resection margin width – 6 (5–14) mm. All patients underwent extensive resection with elements of vascular or biliary resection. Severe complications developed only in half of the patients. No deaths or liver failures were reported. The average duration of hospital stay after surgery amounted to 11 (6–15) days.Conclusion. Robot-assisted liver resections expand the indications for minimally invasive surgeries in intrahepatic cholangiocarcinoma due to patients with locally advanced forms. Satisfactory immediate results justify further accumulation and evaluation of the experience of such interventions.
