21. Factors influencing rehabilitation in patients with head and neck cancerIrena Hočevar-Boltežar, Alojz Šmid, Miha Žargi, Avgust Župevc, Igor Fajdiga, Janez Fischinger, Ana Jarc, 2000, original scientific article Abstract: Purpose. The purpose of the prospective study was to identify the factors adversely influencing the post-treatment rehabilitation in patients with head and neck cancer. Patients and methods. One hundred and ten patients with oral cavity, pharyngeal and laryngeal cancer were examined before surgical treatment in order to find unfavorable factors: hearing loss, defective teeth,impaired pulmonary function, and speech disorders. The patients evaluated the success of their rehabilitation 12 months after the treatment. The influence of possible unfavorable factors, tumor site, and type of surgeryon speech, swallowing and reintegration competence was determinated. Results. The site of the tumor and the type of surgery did not influence the quality of rehabilitation in general. Defective teeth influenced the ability of swallowing but not the speech. Hearing loss impaired the patient's reintegration in their home environment. Impaired pulmonary function did not affect patient's speech. Speech was the poorest in laryngectomized patients. However, about two thirds of the patients were satisfied with their capabilityof speech, swallowing and their rehabilitation in general. Conclusions. Early identification of unfavorable factors, and individually planned rehabilitation can ensure a suitable quality of life for patients thathave undergone surgery for head and neck cancer.

22. How reliable is classic chest radiography in the diagnosis of small pleural effusionIgor Kocijančič, Ksenija Kocijančič, 1999, original scientific article Abstract: Purpose. To evaluate the usefulness of expirium lateral decubitus views in theradiological diagnosis of small pleural effusions. Materials and methods. Patients referred to abdominal sonography for different reasons were routinelychecked for possible pleural effusion. From November 1994 till May 1996, 36 such patients were found to have pleural effusion not exceeding 15 mmand were included in the study. Patients were examined radiologically in erect PA and lateral projections and, after 5 min. in decubitus position, in inspiratory-expiratory lateral decubitus projections with 10 hip elevation andcentral beam on the lateral chest wall. Results. In 22 out of 36 patients (61 %), the pleural fluid was not visible on erect PA and lateral chest radiogram. However, the fluid was visible in 35/36 patients (97%) in expirium from lateral decubitus view. The average thickness of fluid from lateral decubitus views in inspirium and expirium was 4.3 and 7.9 mm, respectively. In31 out of 36 patients (86%), the thickness of the fluid layer as measured inexpirium and inspirium was different. In 16%, the fluid was not visible on inspirium lateral decubitus projections. Conclusions. Radiography turned out to be almost as sensitive as sonography in detection of small pleural effusions. Lateral decubitus views taken in expirium contributed essentially to the diagnostic sensitivity in our study.

23. Experimental and numerical investigation of restrained shrinkage of concreteLucija Hanžič, Jurij Karlovšek, Tomaž Hozjan, Sabina Huč, Zhongyu Xu, Igor Planinc, Johnny Ching Ming Ho, 2020, published scientific conference contribution Abstract: To promote the understanding of shrinkage related behaviour of concrete used for tunnel linings the experimental and theoretical investigation including numerical and analytical approach was performed on ring-shaped specimens. Overall one analytical (an.) and two numerical models, namely (i) and (ii) were also developed. Models (an.) and (i) considered the restraining steel ring to be rigid, thus not exhibiting any deformation. Numerical model (ii) considered the steel ring to be deformable. The experimental set-up consisted of a large concrete ring with an inner diameter of 120 cm, an outer diameter of 160cm and 20 cm in height. The restraining steel ring was 5.5 cm thick. Two concrete rings were made, namely R1 with a low compressive strength of ~26MPa and the other, R2, with medium compressive strength of ~40 MPa. The strain was measured in the hoop direction on the inner circumference of the steel ring and on the outer circumference of the concrete ring. Concrete rings were subjected to circumferential drying. Numerical model (ii) predicted critical time to the formation of the first crack to be between 13 and 14 days. The experimentally determined critical time is found to be 11 to 13 days with cracks gradually opening over several days. This was indicated by changes in measured concrete and steel strain. Modelled concrete strain just before cracking was between -20 and -30 % 10-6 m m-1 however, measured concrete strain was ~150 % 10-6 m m-1. Modelled steel strain was between -30 and -40 % 10-6 m m-1 while measured steel strain was between -10 and 20 % 10-6 m m-1. These discrepancies, in particular the positive steel strain obtained in experiments, require further investigation and improvements of the experimental set-up.

24. Long term follow-up after radiosynovectomy with yttrium 90 in patients with different rheumatic diseasesMojca Golja, Nataša Budihna, Igor Batagelj, 1997, original scientific article Abstract: The aim of the retrospective study was to evaluate the efficacy of radiosynovectomy (with yttrium 90) mainly in patients with rheumatoid arthritis, less with some other rheumatic diseases. The evaluation period varied from half to nine years. The procedure was performed in 273 patients (225 females, 48 males) or in 463 joints (402 knees, 61 shoulders and ankles).The effects was evaluated by change in degree of morning stiffiness, pain and swelling (score from 0 to 9). Very good results were obtained in 69 (15%), good in 142 (30.5%), moderate in 197 (42.5%) and no effect in 55 (12%) joints. Six months after the procedure 38 joints (8%), half to two years after221 joint (48%) were in good remission, after 3 to 4 years 95 joints (20%), after 5 to 6 years 57 joints (12%) were well, 7 to 9 years later 52 joints (11%) showed no signs of arthritis. Joint pain and swelling were the most frequent procedure complications (5.6%). In two patients with additional immunomodulating therapy chronic myeloid and lymphocityc leukaemia were diagnosed. Radiosynovectomy is considered to be an effective and safe treatment for synovitis indifferent rheumatic diseases.

26. Transverse Dinaric zone of increased compression between the Kraški rob and Hrušica Regions, NE MicroadriaLadislav Placer, Igor Rižnar, Ana Novak, 2023, original scientific article Abstract: The Kvarner fault divides the Microadria (Adria microplate, the Adria stable core) into the Po and Adria segments. The Istra block, which is sandwiched between the right-lateral Kvarner Fault and the left-lateral Sistiana Fault lies at the extreme eastern edge of the Po segment. Both faults run transversely to the Dinarides and reach their thrust boundary in the east. The Microadria has been moving towards the Dinarides since the Middle Miocene. The movement of the Istra block is exposed in relation to the neighbouring blocks, so an extensive pushed area (the Istra Pushed Area) was formed in the External Dinarides, which is bent towards the northeast. It is defined by two flexural zones, one lying in the extension of the Sistiana Fault and the other in the extension of the Kvarner Fault. The structure of the Dinaric thrust border on the north-eastern side of the Istra block is complex. Its prominent structural element is the Črni Kal Anomaly, due to which a zone of increased compression developed within the Istra Pushed Area and transversely to the Dinarides (Kraški rob – Hrušica Traverse), which lies between the Sistiana and Kvarner Flexural Zones. In terms of kinematics, it differs greatly from these two, and various geomorphologically responsive deformations have occurred within it. Mt. Vremščica (1027 m), which represents a transpressive anticline within the wider zone of the Raša Fault is the most prominent. In order to understand the genesis of the Classical Karst relief, it is important to know that the Mt. Vremščica ridge rose from the levelled karst surface.
