Prostorna analiza tala i utjecaj na produktivnost u gospodarskoj jedinici Mužljanski rit
The paper presents analysis of soil spatial distribution and productivity of Populus x euramericana I-214 forest cultures in forest management unit (hereinafter: FMU) Muzljanski rit. Soil cover in the FMU is heterogeneous in relation to position and altitude in floodplain. Analysis were conducted on eugley and humogley soil types. Eugley, soil type, was delineated according to physiologically active soil depth as α, β or β/γ gley soils and humogley was delineated as one soil unit. Cultures of the poplar clones Populus x euramericana I-214 are found on at least two but usually more different site types within the same forest management section (18.43 %). Single forest management section is a by definition a single forest spatial unit having similar ecologic factors. Aim of our research was to enable consistent forest section delineation, based on the interaction of soil productivity properties and distribution as well as Populus x euramericana I-214 productivity dataset. Based on our anaysis (spatial analysis of raster layers of soil systematic unit distribution-soil subunit, digital elevation model and productivity according to inner delineation of FMU Muzljanski rit), the resuts show eugley share in lower systematic soil unit. The results show contribution of lower systematic units of eugley in forest managemet section/culture. We found a raising trend of α and β-gley, as well as humogley. On one side the higher contribution of this sistematic units indicates reduction in the forest culture yield. On the other side higher contribution of β/γ gley indicates an increase of culture yeald. The Populus x euramericana I-214 cultures are spatialy concentrated, extending over soil units with different characteristics, pointing in alternative economicaly justified section delineation, based on the soil types.Razumijevanje produktivnosti drveÄa u gospodarskim jedinicama vezano je za poznavanje viÅ”e staniÅ”nih Äimbenika. U radu se prikazuju istraživanja s obzirom na rasprostranjenost tala, dajuÄi im veÄu važnost u odnosu na izbor klona, vodni režim, klimatske ekstreme, kao i postupak obnove nasada. Opravdanost navedenog pristupa je vezana za viÅ”e provedenih istraživanja, u kojima je jedan od osnovnih Äimbenika tip tla, a s njime i odgovarajuÄa vrsta drveÄa.Pregled prostorne rasprostranjenosti tala omoguÄeno je razvojem programskih paketa za prostornu analizu geoinformacijskih podataka. U radu je prikazana analiza prostorne raspodjele tala i produktivnosti nasada Populus x euramericana I-214 gospodarske jedinice (GJ) Mužljanski Rit. Definiranju rasprostranjenosti tala u GJ Mužlјanski rit prethodila je izrada modela terena. Model terena napravljen je na bazi osnovne državne karte (R 1:5000) za definiranje mikrorelјefa. Svaka poznata toÄka je osim vrijednosti na x i y osi, dobila vrijednost i na z osi. U programskom paketu ArcGIS je izvrÅ”ena interpolacija, a rezultat je 3D model terena u GJ Mužljanski rit na povrÅ”ini od približno 1820 ha. Na ovaj naÄin je omoguÄena analizirati ekvidistance na 10 cm na prostoru gospodarske jedinice. Prostornom analizom su prema Klasifikaciji zemlјiÅ”ta Jugoslavije (Å koriÄ i sur., 1985) determinirani razliÄiti tipovi i niže sistematske jedinice tala. Prethodno navedena klasifikacija je nadopunjena podjelom na fizioloÅ”ki aktivnu dubinu profila prema Wildeu (1940), zbog pretpostavljene razliÄite produktivnosti tala ovisno o vrsti stabala koja Äe se tamo uzgajati. Postupak je na ovaj naÄin definirao podruÄja niza i greda na prostoru Äitave GJ, te je poslužio kao osnova za daljnje analize. Mrežom pedoloÅ”kih profila su definirani tipovi tala. Rezultati istraživanja ukazuju da je pokrov tla u istraživanoj GJ heterogen, te su kao tipovi tla determinirani euglej i humoglej. Podjela na niže sistematske jedinice kod eugleja je vezana za fizioloÅ”ki aktivnu dubinu profila i to na α, β ili β/γ glej (ograniÄavajuÄi Äimbenik je stagnacija podzemne vode u profilu). Posljedica je 18,43% nasada Populus x euramericana I-214 koji se nalazi na dvije ili viÅ”e razliÄitih vrsta sustavnih jedinica tala, unutar istog odsjeka, u dijelu Å”ume koja tvori glavnu prostornu jedinicu sa sliÄnom ekologijom. PoveÄanje ili smanjenje udjela sustavne jedinice tla dovodi do postizanja razliÄite produktivnosti. U radu je utvrÄena potreba podjele eugleja kao tipa tla na niže sistematske jedinice. Rezultati istraživanja ukazuju da trendovi poveÄanja udjela α i β-gleja u tlu, kao i humogleja, utjeÄu na smanjenje prinosa nasada Populus x euramericana I-214, dok udio β/γ-gleja (u statistiÄkoj znaÄajnosti od 0,3745) pozitivno korelira s volumenom nasada Populus x euramericana I-214. Iz rezultata je takoÄer vidljivo da je mali udio α gleja (do 10%) dovoljan po povrÅ”ini odsjeka da bi doveo do smanjenja produktivnosti nasada Populus x euramericana I-214, dok je taj udio kod β-gleja neÅ”to veÄi te ne bi trebao prelaziti 20%, odnosno najviÅ”e 30%. Nasadi Populus x euramericana I-214 prostorno su koncentrirani, Å”to ukazuje na alternativnu ekonomski održivu podjelu na temelju karakteristika tala uz izbor odgovarajuÄe vrste drveÄa. Na podruÄju niza je u najveÄoj mjeri zastupljen euglej (fizioloÅ”ki α i β glej) i potrebno ih je izbjegavati, buduÄi da i mali udio navedenih sustavnih jedinica zemljiÅ”ta bitno utjeÄe na produktivnost, a posljediÄno i na sortimentne strukture nasada Populus x euramericana I-214. U najveÄem broju sluÄajeva, kao zamjenska vrsta na humoglejevima i fizioloÅ”ki pliÄim sustavnim jedinicama bio bi hrast lužnjak kao stabilna i vitalna vrsta. Na osnovi prostornog rasprostranjenja tala to se vrlo jasno može definirati, a u konaÄnici se i ispunjavaju ostale funkcije Å”uma
The Possibilities and Limitations of Direct Digital Radiography, Ultrasound and Computed Tomography in Diagnosing Pleural Mesotelioma
The goal of this study was to compare the possibilities and limitations of direct digital radiography of the chest (DDR), the use of ultrasound of the chest (US) and single slice computed tomography of the chest (CT) in diagnosing pleural mesothelioma. The study was conducted during the course of one year, on 80 patients who were successively referred to a specialized institution, under clinical suspicion of mesothelioma. The method of investigation was the comparison of findings, obtained by the reviewed methods of examination, with the pathohistologic results of a biopsy performed on each patient. The findings that were obtained by the enumerated methods were classified according to the radiologic signs that were found in each individual patient. We evaluated following radiological findings (signs), on each of the investigated methods: plaques, localized and generalized pleural thickenings, calcifications of the pleura, pleural effusions, parapneumonic effusions, pleural empyema, (round) atelectasis, pneumothorax, tumor mass or node, inflammatory infiltrate, elevation of the hemidiaphragm and osteolysis. The results of these were compared with pathohistologic findings and analyzed by means of standard statistical methods. The highest sensitivity was found for CT (94.4 %), followed by US (92.6%), and by DDR (90.7%). The highest specificity was obtained with DDR (46.2 %), followed by CT (35.5%) and US (23.8%). The comparison of these methods showed 90% diagnostic accuracy for DDR in relation to CT. CT as an individual method best satisfied most of the criteria for diagnosing mesothelioma. No pathognomonic radiologic sign for mesothelioma was found

Stenotic occlusive lesions of internal carotid artery in diabetic patients
Diabetes deteriorates atherosclerotic changes in the arteries. The aim of the study was to assess the prevalence and localization of stenotic atherosclerotic lesions of the internal carotid artery (ICA) in patients with diabetes. A prospective analysis of angiography findings was carried out in 150 diabetic and 150 non-diabetic patients with symptoms of cerebral ischemia using double-blind angiogram readings by two independent investigators. The degree of stenosis was determined using the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Stenoses of the proximal arterial segment accounted for the majority of extracranial ICA stenoses, being more frequent in diabetic (left ICA 50.7%, right ICA 58.0%) than in the non-diabetic patients (left ICA 29.3%, right ICA 32.7%). Diabetic patients revealed a more significant rate of unilateral tandem ICA stenoses (14.0-21.3%), as well as a statistically significantly higher prevalence of intracranial ICA stenoses (left ICA 24.0% and right ICA 17.3%) than did non-diabetic patients (left and right ICA 3.3% each). Our results confirm that there is a morphological basis in ICA for increased incidence of ICA lesions in patients with diabetes as compared to those without it. Data on the incidence of stenotic ICA lesions in diabetes suggest the importance of assessing overall ICA status using digital subtraction angiography. Such an assessment is a precondition for an optimal therapeutic approach, especially in diabetic patients who are at an increased risk of cerebrovascular disease
