1. Exploring the mesoscale connectivity of phytoplankton periodic assemblages' succession in northern Adriatic pelagic habitatsIvano Vascotto, Fabrizio Bernardi Aubry, Mauro Bastianini, Patricija Mozetič, Stefania Finotto, Janja Francé, 2024, original scientific article Abstract: An appropriate model for phytoplankton distribution patterns is critical for understanding biogeochemical cycles and trophic interactions in the oceans and seas. Because phytoplankton dynamics in coastal waters are more complex due to shallow depth and proximity to land, more accurate models applied to the correct spatial and temporal scales are needed. Our study investigates the role of the atmosphere and hydrosphere in pelagic habitat by modelling phytoplankton assemblages at two Long Term Ecological Research sites in the northern Adriatic Sea using niche-forming environmental variables (wind, temperature, salinity, river discharge, rain, and water column stratification). To study the synchronization between the phytoplankton community and these environmental variables at the two LTER sites, we applied current linear and nonlinear numerical methods for ecological modelling. The aim was to use periodic and/or non-periodic properties of the environmental variables to classify the phytoplankton assemblages at one LTER site (Gulf of Trieste - Slovenia) and then predict them at another LTER site 100 km away (Gulf of Venice - Italy). We found that periodicity played a role in the explanatory and predictive power of the environmental variables and that it was more important than non-periodic events in defining the common structure of the two pelagic habitats. The non-linear classification functions of the neural networks further increased the predictive power of these variables. We observed partial synchronization of communities at the mesoscale and differences between the original and predicted assemblages under similar environmental conditions. We conclude that mesoscale connectivity plays an important role in phytoplankton communities in the northern Adriatic. However, the loss of periodicity of niche-forming variables due to more frequent extreme meteorological and hydrological events could loosen these connections and affect the temporal succession of phytoplankton assemblages.

3. Pozicioniranje in kontrola kakovosti mamogramaZvonko Krajnc, Miljeva Rener, Alenka Rataj, Patricija Rusjan, Gregor Novak, Katja Čebulj, 2004, published scientific conference contribution Abstract: Izhodišča. Pravilno pozicioniranje je predpogoj za zagotavljanje kakovosti mamografskih slik. Zato je pomembno, da dobro poznamo anatomijo in tehnike pozicioniranja, slikanja in razvijanja. Zaključki. Da bi dosegli optimalen prikaz tkiv, rnorarno pravilno nastaviti nosilec kasete in kompresorij ter izkoristiti premakljivost dojk, pomembna pa je tudi pravilna uporaba aparatur.Ob izvajanju mamografije moramo nujno upoštevati kriterije za kontrolo kakovosti. Pri tem nam pomaga pravilnik o pogojih, ki jih morajo izpolnjevati primarni centri za dojke v Republiki Sloveniji, ter evropske smernice. S kontrolo kakovosti bomo u Sloveniji zvišali kvaliteto in s tem prispevali k čirn zgodnejšemu odkrivanju sprememb na dojkah.

4. Ciljana kompresija in povečavaPatricija Špeh, Andreja Kokot, Brigita Hudales, 2001, published professional conference contribution Abstract: Ciljano kompresijo in povečavo uporabljamo, kadar želimo razjasniti sumljive nepravilnosti, ki so vidne na osnovnih mamogramih. Ciljana kompresija nam omogoči razmik tkiva, medtem ko povečavo največkrat uporabljamo za boljši prikaz mikrokalcinacij. Včasih pa obe kombiniramo.

5. Dodatne projekcije (cleveage, tangencialna projekcija, slikanje vsadkov, moška dojka)Andreja Kokot, Brigita Hudales, Patricija Špeh, 2001, published professional conference contribution Abstract: V prispevku so opisana specialna slikanja, ki jih uporabljamo pri mamografijah. Mednje sodijo: cleavage, tangencialna projekcija, slikanje vsadkov in moške dojke. Z natančno tehnično izvedbo teh preiskav marsikdaj lahko rešimo nadaljno diagnostiko in operativno obdelavo.

6. ML, LM, XCC, rolled-on projekcijeBrigita Hudales, Andreja Kokot, Patricija Špeh, 2001, published professional conference contribution Abstract: V poglavju opisujem dodatne projekcije za slikanje dojke, med katere spadajo naslednje projekcije: - stranska mediolateralna projekcija ML - stranska lateromedialna projekcija LM - pretirano medialna projekcija XCCM - pretirano lateralna projekcija XCCL - rolled-on ali zavrtena projekcija V praksi med opisanimi projekcijami največkrat izvajamo ML projekcijo, sledita obe XCC projekciji. Pred izvajanjem projekcije vedno pripravimo kaseto ustreznega formata (18x24 ali 24x30), namestimo rentgensko cev v ustrezen položaj in izberemo ustrezno ekspozicijo. Dojko poskušamo vedno dobro komprimirati. Pri projekcijah sta posebej pomembna natančnost in seveda tudi sodelovanje pacientke, kajti le obojestranski trud da rezultat- kakovosten in diagnostičnouporaben rentgenogram; to pa je zelo pomembno za zgodnje odkrivanje sprememb na dojkah.
