Specific aspects of engineering-geological models in Croatian karst terrain

The experiences of developing engineering geological models in karst areas for designing and construction purposes prove the necessity of considering at least three basic submodels: sedimentological, structural-tectonic and the weathering one. The research presented here deals with very important and frequently neglected segments in each of the submodels. Therefore, particular attention should be directed to: better understanding of carbonate sediment deposition, determination of environment and diagenetic processes, study of the 3D anisotropy of discontinuity frequency, and differentiation of weathering zones. The given data and examples elaborate and justify such an approach, which enables a more realistic detailed engineering model, more reliable evaluations of the engineering geological/geotechnical parameters and real site conditions

Poduzetnički mitovi (ili stvarnosti) i poduzetničke namjere

The development of modern entrepreneurship research began some 50 years ago. In the meantime, various definitions of entrepreneurship led to different interpretations of its scope, and subsequently, the entrepreneurial myths emerged. This topic was studied quite intensively in the 1980s and 1990s, and numerous results succeeded in demystifying most of the entrepreneurial myths. Despite that, the entrepreneurial myths persist and regularly appear on the web portals, media, and bloggers’ articles. On the other side, contemporary entrepreneurship textbooks include entrepreneurial myths as a lesson which could eliminate some obstacles for the nascent entrepreneurs. This study revealed that the entrepreneurial myths are somewhat present among younger examinees, nonentrepreneurs in Croatia, who have a low or medium level of education. Still, not even these demographic groups view those myths as realities. Further analysis pointed out that there is a statistically significant, although negative and weak correlation between the perception of entrepreneurial myths as myths (not as realities) and a higher level of entrepreneurial intentions.Razvoj suvremenih istraživanja u području poduzetništva započeo je prije pedesetak godina. U međuvremenu, ponuđene su različite definicije poduzetništva koje su dovele do raznolikih interpretacija obuhvata poduzetništva te naposlijetku do nastanka poduzetničkih mitova. Ova tema je intenzivno istraživana 1980-ih i 1990-ih te su brojni rezultati uspješno demistificirali većinu poduzetničkih mitova. Usprkos tome, poduzetnički mitovi opstaju i redovito se pojavljuju na web portalima, u medijima i člancima blogera. S druge strane suvremeni udžbenici poduzetništva uključuju poduzetničke mitove kao lekciju koja može eliminirati neke prepreke za nove poduzetnike. Ovim istraživanjem utvrđeno je da su poduzetnički mitovi ponešto prisutni među mlađim, niže obrazovanim, ispitanicima ne-poduzetnicima u Hrvatskoj. Ipak, niti ove skupine ispitanika u prosjeku ne drže poduzetničke mitove, realnošću. Daljnja analiza je istaknula da postoji statistički značajna, ali slaba i negativna povezanost između percepcije poduzetničkih mitova kao mitova (ne kao realnosti) i više razine poduzentičkih namjera

Hemangiopericitom ili hemangiopericitomu nalik tumor jednjaka: prikaz slučaja i pregled literature

Hemangiopericytoma is a rare malignant vascular tumor deriving from pericytes. It usually occurs in the extremities and retroperitoneum, and extremely rarely in the gastrointestinal tract. A case of hemangiopericytoma in the gastroesophageal region is reported. A 56-year-old man was treated with H2-receptor antagonist for dyspeptic symptoms that had occurred three months before. Therapy failed to prove successful and gastroendoscopy was performed in March 2001 to reveal slightly reddish ventricular mucosa with normal rugal folds and a sessile, polypoid, grayish mass of rough surface located at the gastroesophageal junction. Histopathologic examination of polypoid mass samples revealed a vascular tumor covered with squamous epithelium. The hallmarks of the tumor were numerous branching, slit-like capillary channels with "staghorn" appearance, and large gaping sinusoidal spaces enclosed within nests of ovoid cells. Vascular invasion, mitotic activity, giant cells and necrosis were not found. Immunohistochemical analysis showed diffuse and strong reactivity for vimentin and focal, low or moderate reactivity for actin, S-100 and smooth muscle actin. Proliferation index measured by PCNA and Ki-67 ranged from 2% to 13% (median 11.2%) and from 5% to 18% (median 7.6%), respectively. A diagnosis of hemangiopericytoma with low malignant potential was made. Almost two years of the intervention, the patient is alive and free from any signs of tumor spread.Hemangiopericitom je rijedak maligni vaskularni tumor koji potječe od pericita. Najčešće je javlja na ekstremitetima, te u području peritoneuma, a iznimno rijetko ga se nalazi u probavnom sustavu. Opisuje se slučaj hemangiopericitoma nađenog u gastroezofagusnom području. Bolesnik star 56 godina liječen je tri mjeseca antagonistima H-2 receptora zbog dispeptičnih problema. Preporučena terapija nije pokazala očekivani rezultat, pa je učinjena gastroskopija. Nađena je sesilna polipozna tvorba veličine novčića, sivkaste boje i neravne površine u gastroezofagusnom području. Histopatološki je odstranjena tvorba bila građena od razgranatih kapilarnih prostora tipa "staghorn", okruženih gnijezdima ovalnih stanica koje su tvorile solidan uzorak. Nekroze, vaskularna invazija, velike stanice i mitoze nisu nađene. Tumorske stanice su pokazivale difuznu, izrazito pozitivnu imunoreakciju na vimentin, dok je reakcija na aktin, S-100 i glatkomišićni aktin bila žarišna i slabog intenziteta. Proliferacijska aktivnost tumora iznosila je između 2% i 13% (medijan 11,2%) mjerena pomoću PCNA, te između 5% i 18% (medijan 7,6%) mjerena pomoću Ki-67. Postavljena je dijagnoza hemangiopericitoma niskog malignog potencijala. Skoro dvije godine nakon postavljene dijagnoze bolesnik je bez znakova bolesti

Statistical Analysis and Interpretation of Building Characterization, Indoor Environmental Quality Monitoring and Energy Usage Data from Office Buildings and Classrooms in the United States

Three independent tasks had been performed (Stetzenbach 2008, Stetzenbach 2008b, Stetzenbach 2009) to measure a variety of parameters in normative buildings across the United States. For each of these tasks 10 buildings were selected as normative indoor environments. Task 1 focused on office buildings, Task 13 focused on public schools, and Task 0606 focused on high performance buildings. To perform this task it was necessary to restructure the database for the Indoor Environmental Quality (IEQ) data and the Sound measurement as several issues were identified and resolved prior to and during the transfer of these data sets into SPSS. During overview discussions with the statistician utilized in this task it was determined that because the selection of indoor zones (1-6) was independently selected within each task; zones were not related by location across tasks. Therefore, no comparison would be valid across zones for the 30 buildings so the by location (zone) data were limited to three analysis sets of the buildings within each task. In addition, differences in collection procedures for lighting were used in Task 0606 as compared to Tasks 01 & 13 to improve sample collection. Therefore, these data sets could not be merged and compared so effects by-day data were run separately for Task 0606 and only Task 01 & 13 data were merged. Results of the statistical analysis of the IEQ parameters show statistically significant differences were found among days and zones for all tasks, although no differences were found by-day for Draft Rate data from Task 0606 (p>0.05). Thursday measurements of IEQ parameters were significantly different from Tuesday, and most Wednesday measures for all variables of Tasks 1 & 13. Data for all three days appeared to vary for Operative Temperature, whereas only Tuesday and Thursday differed for Draft Rate 1m. Although no Draft Rate measures within Task 0606 were found to significantly differ by-day, Temperature measurements for Tuesday and Thursday showed variation. Moreover, Wednesday measurements of Relative Humidity within Task 0606 varied significantly from either Tuesday or Thursday. The majority of differences in IEQ measurements by-zone were highly significant (p<0.001), with the exception of Relative Humidity in some buildings. When all task data were combined (30 buildings) neither the airborne culturable fungi nor the airborne non-culturable spore data differed in the concentrations found at any indoor location in terms of day of collection. However, the concentrations of surface-associated fungi varied among the day of collection. Specifically, there was a lower concentration of mold on Tuesday than on Wednesday, for all tasks combined. As expected, variation was found in the concentrations of both airborne culturable fungi and airborne non-culturable fungal spores between indoor zones (1-6) and the outdoor zone (zone 0). No variation was found among the indoor zones of office buildings for Task 1 in the concentrations of airborne culturable fungi. However, airborne non-culturable spores did vary among zones in one building in Task 1 and variation was noted between zones in surface-associated fungi. Due to the lack of multiple lighting measurements for Tasks 13 and 0606, by-day comparisons were only performed for Task 1. No statistical differences were observed in lighting with respect to the day of collection. There was a wide range of variability by-zone among seven of the office buildings. Although few differences were found for the brightest illumination of the worksurface (IllumWkSfcBrtst) and the darkest illumination of the worksurface (IllumWkSfcDrkst) in Task 1, there was considerable variation for these variables in Task 13 and Task 0606 (p < 0.001). Other variables that differed by-zone in Task 13 include CombCCT and AmbCCT1 for S03, S07, and S08. Additionally, AmbChromX1, CombChromY, and CombChromX varied by-zone for school buildings S02, S04, and S05, respectively. Although all tasks demonstrated significant differences in sound measurements by zone, some of the buildings within each task did not appear to differ in sound quality. Hence, post-hoc tests were not appropriate and individual zones were not compared for these buildings. It is interesting to note that sound measurements in some buildings were widely varied with most zone comparisons and other buildings varied between only a few zones
