This document refers to the non-stationary heat conduction through transparent thermal insulators. Non-stationary heat transfer means that temperature varies in time, in all points of the thermal field. Temporal and spatial distributions of the temperature inside of the sample are experimentally determined.

Unfortunately on May 14th, 2015 our colleague and friend Assa Reichert lost his battle against his difficult disease. Assa, Reichert, our very long time member of Board and Council of European Federation for Medical Informatics (EFMI), was our a true friend. He devoted to his family, his country, his friends, his profession and EFMI, IMIA and Medical informatics, generally. As Medical informatics expert and scientist he was “elder statesman” (how one of our colleagues defined him) and has been a person with great treasure of warmth and experiences and man carrying a peaceful vision of the world. He would be right person from whom always you can ask some advice for solving some difficult problems or situations. During all EFMI events Assa has showed his true commitment to the Medical Informatics field. Especially he inspiring the young scientists with his always charming, witty and thoughtful remarks. He always supported people who invested their time and efforts to produce himself as a little interface for the ultimate human EFMI network like “Key success-factor” as Jacob Hofdijk mentioned in his memory letter. MIE 2009 Conference in Sarajevo organized by myself Assa promoted and supported by great influence on important decision makers in our country and abroad. Assa Reichert directed the first computer department in the Israel Ministry of Health. He was assistant director of Sheba Medical Centre, the largest in Israel, and VP of COMET, an Israeli-American software house specializing in medical institution management and Electronic Medical Record’s software. He served as consultant to the Ministry of Health. Assa achieved a BA in Life sciences and a MA in Life sciences and Computer sciences from Bar-Ilan University, Israel. Assa served as President of the European Federation for Medical Informatics (EFMI) during a period 20022003, and served as Vice-President of the International Medical Informatics Association (IMIA) during a period 2004-2005. During STC EFMI Conference in Reykjavik, Iceland, Assa received the medal as Honorary Fellow of EFMI. We will remember him for all his contributions and commitment in the different roles he has held during his time in EFMI. All of us in EFMI and IMIA lost one of prominent personality. His voice and his deep thoughts for best and most reasonable solutions in critical situations during our Council meetings will persist in our minds. His way of discussing about important problems was typical. He was straight, but always in a fair way. The best way to keep his memory is to continue his plans and to follow his example. His “presence” in our minds will not be felt and will touch every EFMI and IMIA friend’s soul and heart. Assa was living on the edge with his dedication to his motorbike and his endless (business) travels around the world, and survived many near miss accidents, always returning with a smile, never complaining, but fight against lung cancer he couldn’t won, unfortunately. Everybody of us will miss his friendship, honesty and his ethos. We will remember Assa with deepest admiration, compassion and desolation.

HEINZ ZEMANEK (1920-2014) Heinz Zemanek was born January 1, 1920 in Vienna, Austria. He was Austrian computer scientist who developed the MAILUFTERL computer, and while director of the IBM Laboratory in Vienna. He directed the development of formal programming language descriptors (1). He studied low-voltage technology at the Technical University of Vienna, and was appointed as an assistant at the Institute for Low-Voltage Technology where he received his PhD in engineering. Heinz Zemanek graduated at Technical University of Vienna in 1944. He earned PhD (Dr. Techn., engineering) at Technical University of Vienna in 1951.

The celebration at the Technical Museum of Vienna was also the occasion to present the Heinz Zemanek Award to a young Austrian computer scientist.

Total atrioventricular (AV) block is inconvenient and serious complication of open heart surgery. Permanent total AV block requires the implantation of permanent pacemaker in order to allow normal hemodynamics and patient’s survival. In infancy additional challenge is the surgical approach, the selection of electrodes and PM, as well as place of implantation. We are publishing case report of successful double-chamber DDD pacemaker implantation at an infant born with Fallot tetralogy and with low birth weight due to complete AV block after primary surgical correction of these congenital defects.

Introduction. Urolithiasis is a multifactorial disease. Changes in social and economic living conditions have generated changes in chemical composition of urolith too. Although calcium is a predominant crystalline constituent of kidney stones in 80% of cases, metabolic disorders are not the main reason for their formation. Hyperparathyroidism may be a cause of occurrence of calcium lithiasis, however, the biggest number of its occurrence is not a consequence of elevated values of parathormone. Acid uric has a pervasive presence in all body fluids. The serum level of acid uric is determined by its rate of synthesis, rate of excretion by kidney and gastrointestinal tract, and metabolism. Goal. The goal of our study is to determine a correlation of calcium lithiasis of the upper part of the urinary tract with the parathormone values and the concomitant values of acidum uricum. Material and methods. The study was prospective and included 120 patients with calcium lithiasis of the upper part of urinary tract, divided in three age categories, 20-40 years, 40-60 years and older than 60 years. The diagnosis of calcium lithiasis of the upper part of the urinary tract was made on the basis of urinary tract ultrasonography, and kidney-ureter-bladder radiography (KUB) /intravenous urography (IVU), urine culture and chemical analysis of stone with patients who had a spontaneous emission of stone or following some of the methods for active removal of stone; with some patients non-contrast (NCCT) was carried out too. All patients were subjected to the laboratory analysis of the serum level of acidum uricum and parathormone. Results. With observed 120 patients suffering from calcium urolithiasis, who belonged to adult population, no patient had an elevated value of parathormone, while three patients (2.5%) had the values of acidum uricum higher than the reference values. The average value (for both parameters) was the lowest with the youngest patients and vice versa, and only in the group of 40 to 60 years of age there were patients whose values of the acidum uricum parameter was outside the interval of reference values; the other age groups did not have such values. Based on the analysis of the variance, as a statistical method, it was determined that the average values of acidum uricum in different age groups were statistically significantly different, which is not the case for the parameter parathormone. (p>0,05). Conclusion. The biggest number of nephrolithiasis is not a consequence of elevated values of parathormone. Hyperuricosemia may be present with calcium urolithiasis, without participation in forming kidney stones, most probably as an indirect sign of the existence of the initial insulin resistance and metabolic disease.

Introduction: The purpose of the current study was to estimate the biocompatibility of endodontic sealers with different bases on L929 mouse fibroblasts permanent cell line using Multiscan EX Spectrophotometer. Materials and Methods: Endodontics sealers used in this study were GuttaFlow (Roeko) silicone based sealer, AH plus (De Tray-DENTSPLY) epoxy resin based, Apexit (Vivadent) calcium hydroxide based and Endorez (Ultradent) methacrylate based sealer. Sealer were tested trough time, freshly mixed 24 h, 48h and 7 days after setting. Biocompatibility was determinate on permanent cell lines L929 mouse fibroblasts trough cytotoxicity using MTT assay. Level of absorption was measured with multi scan EX spectrophotometer on length 420-600 nm. Results: Sealer based on calcium hydroxide Apexit Plus, GuttaFlow silicone based sealer and AH plus epoxy resin based sealer, have shown a low cytotoxicity through the all periods of time on culture of L292 mouse fibroblasts. Methacrylate based sealer, Endorez showed moderate cytotoxicity when freshly mixed and after 7 days. After 24 hours the visibility of the cells was 74,0% and after 48 hours 65,1%. which is slightly cytotoxic. Conclusions: According to results of this study there is a statistically significant difference among the groups p<0,05 for all the tested sealers. Apexit Plus, GuttaFlow and AH plus can be considered as biocompatibile. EndoREZ sealer which is based on methacrylate, after 7 days shows 50,1% of visible live cells which is considered as moderate cytotoxicity.
