The frozen elephant trunk procedure is a well-established technique for the repair of type A ascending aortic dissection and complex aortic arch pathology. The ultimate shape created by the repair ...may have consequences in long-term complications. The purpose of this study was to apply a machine learning technique to comprehensively describe 3-dimensional aortic shape variations after the frozen elephant trunk procedure and associate these variations with aortic events.
Computed tomography angiography acquired before discharge of patients (n = 93) who underwent the frozen elephant trunk procedure for type A ascending aortic dissection or ascending aortic arch aneurysm was preprocessed to yield patient-specific aortic models and centerlines. Aortic centerlines were subjected to principal component analysis to describe principal components and aortic shape modulators. Patient-specific shape scores were correlated with outcomes defined by composite aortic event, including aortic rupture, aortic root dissection or pseudoaneurysm, new type B dissection, new thoracic or thoracoabdominal pathologies, residual descending aortic dissection with residual false lumen flow, or thoracic endovascular aortic repair complications.
The first 3 principal components accounted for 36.4%, 26.4%, and 11.6% of aortic shape variance, respectively, and cumulatively for 74.5% of the total shape variation in all patients. The first principal component described variation in arch height-to-length ratio, the second principal component described angle at the isthmus, and the third principal component described variation in anterior-to-posterior arch tilt. Twenty-one aortic events (22.6%) were encountered. The degree of aortic angle at the isthmus described by the second principal component was associated with aortic events in logistic regression (hazard ratio, 0.98; 95% confidence interval, 0.97-0.99; P = .046).
The second principal component, describing angulation at the region of the aortic isthmus, was associated with adverse aortic events. Observed shape variation should be evaluated in the context of aortic biomechanical properties and flow hemodynamics.

U radu su prikazani rezultati trogodišnjih istraživanja gospodarskih svojstava dviju komercijalnih (Désirée i Colomba) i dviju tradicijskih sorata krumpira (Poli i Brinjak) u sjeverozapadnoj ...Hrvatskoj. Istraživanje je provedeno tijekom 2020., 2021. i 2022. godine na pokušalištu Agronomskoga fakulteta Sveučilišta u Zagrebu u uvjetima bez navodnjavanja. Značajno najveći prinos gomolja (33,10 t ha-1) ostvaren je u 2020. godini, u kojoj je tijekom vegetacije palo najviše oborina (583,6 mm). U trogodišnjem prosjeku, signifikantno najveći prinos gomolja ostvarile su sorte Désirée (27,37 t ha-1) i Poli (26,17 t ha-1). Najveći udio suhe tvari utvrđen je kod sorata Poli (23,37 %) i Brinjak (23,26 %), a najmanji kod sorte Colomba (17,39 %). U 2020. godini, koja je za krumpir bila vremenski povoljna, najveći udio u prinosu gomolja imala je frakcija > 55 mm, a u nepovoljnim godinama frakcija 35 – 55 mm. Unutar frakcije > 55 mm, najveći udio gomolja imala je sorta Désirée, a unutar frakcije 35 – 55 mm sorte Poli i Brinjak. U prosjeku, najveći udio sitnih gomolja (manjih od 35 mm) imala je sorta Poli, a najveći udio krupnih gomolja (većih od 55 mm) sorta Colomba. Najveći broj gomolja po biljci utvrđen je kod sorte Poli, a najveća masa gomolja po biljci kod sorte Désirée. Iako su tradicijske sorte krumpira u nekim svojstvima inferiorne u odnosu na komercijalne, nužno ih je ozdraviti od virusa i očuvati (on-farm) radi održavanja bioraznolikosti i raznolikosti u gastronomskoj ponudi.
Pšenica je po proizvodnji druga najvažnija ratarska kultura u Republici Hrvatskoj. Uvođenjem Kodeksa otkupa žitarica i uljarica, pored uroda zrna, sve veća važnost poklanja se parametrima kvalitete ...zrna pšenice, prvenstveno sadržaju proteina i hektolitarskoj masi, koji direktno utječu na cijenu pšenice prilikom otkupa. Genetski potencijal sorte kao i okolinski uvjeti izravno utječu na navedene parametre. Trogodišnjim istraživanjem provedenim na lokaciji Staro Topolje na 12 sorti ozime pšenice, uzgajanim pri tri različite razine gnojidbe dušikom, procijenjen je utjecaj godine, sorte i tretmana dušičnim gnojivom na sadržaj proteina, hektolitarsku masu i masu 1000 zrna. Prema dobivenim rezultatima utvrđen je signifikantan utjecaj godine, sorte i tretmana dušičnim gnojivom na sadržaj proteina. Najveći utjecaj na ovo svojstvo imala je godina, zatim tretman dušičnim gnojivom, a najmanji sorta. Signifikantan utjecaj godine i sorte utvrđen je i za hektolitarsku masu, dok tretman dušičnim gnojivom nije signifikantno utjecao na ovo svojstvo, uz činjenicu da je utjecaj godine bio znatno veći u odnosu na sortu. Također je utvrđeno da su sve testirane sorte jednako reagirale na tretman dušičnim gnojivom. Prosječni sadržaj proteina pri najnižoj količini primijenjenog dušičnog gnojiva iznosio je 11,08 %, pri srednjoj 11,95 %, a pri najvišoj 12,89 %.
Wheat is the second most important crop in the Republic of Croatia. With the introduction of the Code of the purchase of grains and oilseeds, in addition to grain yield, increasing importance is attached to the parameters of wheat grain quality, primarily protein content and test weight, which directly affect the wheat price at purchase. The genetic potential of the variety as well as the environmental conditions directly affect the stated parameters. Three-year research conducted at the location of Staro Topolje on 12 winter wheat varieties grown under three different levels of nitrogen fertilization, evaluated the effect of year, variety and treatment with nitrogen fertilization on protein content, hectolitre mass and thousand seed weight. For protein content significant effects of the year, variety and treatment with nitrogen fertilizer were determined. The year had the greatest effect on this trait, then treatment with nitrogen fertilizer, and the variety had the smallest effect. Significant effects of year and variety were also found for hectolitre mass, while treatment with nitrogen fertilizer did not significantly affect this trait, with the effect of year being considerably higher as compared to the effect of variety. It was also observed that all tested varieties responded equally to nitrogen fertilizer treatment. The average protein content at the lowest amount of applied nitrogen fertilizer was 11,08%, at the medium 11,95%, and at the highest 12,89%.

Istraživanje je obavljeno na stablima maslina sorte Maurino starosti 7 godina. Precjepljivanje je obavljeno sa sortama Buža, Istarska bjelica i Pendolino krajem travnja 2011., stavljanjem plemki pod ...koru. U nasadu su se tijekom vegetacije obavljale sve potrebne agrotehničke mjere, od međuredne obrade tla do zaštite od bolesti i štetnika. Tijekom vegetacije smo pratili primitak cijepljenja i mjerili vegetativni porast izboja na plemkama po sortama. Također smo pratili utjecaj grana “hraniteljica”, od kojih smo neke i prstenovali, na postotak primitka cijepljenja, kao i na vegetativni porast novih izboja. Tijekom jednogodišnjeg praćenja i mjerenja, ustanovili smo da je sorta glavni čimbenik koji utječe na dužinu porasta novih izboja. Postotak primitka je bio 95%. Kod stabala s ostavljenim granama “hraniteljicama” bilo je manje izboja na primarnim granama i deblu precjepljivanih stabala
Posljednjih deset godina svjedoci smo klimatskih promjena uslijed djelovanja različitih štetnih utjecaja na okoliš. U poljoprivrednoj proizvodnji rješenja se sve više traže u ekološkoj proizvodnji ...koja se temelji na korištenju metoda koje ne ometaju prirodne zakone te ne djeluju štetno na agroekološki sustav kao ni na zdravlje ljudi. S obzirom na velike troškove sadnje novog sortimenta prilikom prelaska na ekološku proizvodnju, cilj ovog istraživanja je bio utvrditi osjetljivost standardnih sorti na glavnu bolest jabuke, mrljavost lista i krastavost ploda (Venturia inaequalis), u sustavu ekološke zaštite u usporedbi s kontrolom tj. ne tretiranim djelom pokusa. Drugi cilj je bio utvrditi učinkovitost ekološkog tretmana na otpornom ili tolerantnom sortimentu jabuke. Dvogodišnji rezultati istraživanja pokazali su da su sorte 'Elshof' i 'Elstar' pokazale najmanju osjetljivost plodova na krastavost u ekološkom tretmanu ali i u usporedbi sa svim ostalim standardnim sortama u istraživanju. Od tolerantnih sorti najvišu otpornost je pokazala sorta 'Enterprise'. Sorta 'Priam' se također pokazala kao pogodna sorta za ekološki uzgoj i zadržala je stabilnost priroda u obje istraživane godine.
During the last decade, we are witnessing climate change, occurring due to the various impacts harmful to the environment. In agricultural production, solutions are sought in organic production. The goal of organic production is to achieve high productivity and quality of the products by relying on the use of methods that do not interfere with natural equilibrium and do not have negative affect on agro-ecological system as well as human health. Considering the high cost of new planting when switching to organic production, the aim of this study was to determine the susceptibility of standard varieties to apple scab (Venturia inaequalis), the most important disease of apple, in organic pest control programme compared with control. Another goal was to determine the effectiveness of organic pest control programme on tolerant apple varieties compared to control. This research was conducted at the Agricultural Institute Osijek, Department for Fruit Growing and it lasted for two years (2011 - 2012). A total of 29 apple varieties were included in the study. Two-year research results showed that ‘Elshof’ and ‘Elstar’ varieties were the most resistant to the disease in organic treatment compared to control, but also compared to all the other standard varieties in the study. Among tolerant varieties, the best result was recorded for ‘Enterprise’ variety, while ‘Priam’ variety showed a good result within the organic pest control programme and maintained the stability of the yield in both investigated years.

U trogodišnjim poljskim ispitivanjima utvrđen je utjecaj godine, tretmana navodnjavanja i sorte na visinu biljaka i urod zrna soje u uvjetima istočne Hrvatske. Statistički vrlo značajan utjecaj ...(P=0,01) na visinu biljaka soje pokazuju sva tri ispitivana faktora, kao i njihove interakcije, izuzev interakcije navodnjavanja i sorte koja je bila značajna na razini P=0,05. Na urod zrna soje ispitivani faktori, kao i sve njihove interakcije, utječu na razini značajnosti P=0,01. Dobivene vrijednosti uroda zrna soje tijekom istraživanja (uglavnom veće od 3000 kg ha-1), ukazuju na važnost odabira sorte i tretmana navodnjavanja u prilagodbi proizvodnje soje nepovoljnim vremenskim utjecajima godine.
