Implantation of the modified endocapsular bending ring in pediatric cataract surgery using a viscoadaptive viscoelastic agent.
1999
Cataract surgery and intraocular lens (IOL) implantation in pediatric eyes remain controversial. Using a viscoadaptive viscoelastic agent, we implanted a modified capsular bending ring (CBR) as well as an acrylic IOL with a sharp-optic-edge design in the capsular bag. All operated eyes demonstrated a low postoperative inflammatory reaction and a clinically well-centered IOL. The band-shaped, sharp-edged CBR facilitates the creation of a sharp, discontinuous bend in the equatorial capsule, which prevents anterior and posterior capsule opacification. Combining the viscoadaptive viscoelastic agent and the CBR enhances the safety of primary and secondary posterior chamber IOL implantation in pe…
Going beyond histology. Synchrotron micro-computed tomography as a methodology for biological tissue characterization: from tissue morphology to indi…
2009
Current light microscopic methods such as serial sectioning, confocal microscopy or multiphoton microscopy are severely limited in their ability to analyse rather opaque biological structures in three dimensions, while electron optical methods offer either a good three-dimensional topographic visualization (scanning electron microscopy) or high-resolution imaging of very thin samples (transmission electron microscopy). However, sample preparation commonly results in a significant alteration and the destruction of the three-dimensional integrity of the specimen. Depending on the selected photon energy, the interaction between X-rays and biological matter provides semi-transparency of the spe…

Wiadomości o rudzkim opactwie cystersów – na podstawie dokumentu fundacyjnego z kapsuły czasu kościoła w Stanicy z 1802 r
2019
12 grudnia 2017 r. zdjęto krzyż z kulą z wieży kościoła parafialnego pw. św. Marcina w Stanicy – ostatniej świątyni zbudowanej przez opactwo cystersów w Rudach przed jego kasatą w 1810 r. W kapsule czasu znajdował się okolicznościowy zapis, sporządzony 20 września 1802 r. W oparciu o lekturę odkrytego dokumentu oraz dostępne opracowania na temat rudzkiego opactwa, autor omawia sytuację opactwa na początku burzliwego XIX w., a także charakteryzuje stan osobowy rudzkiego konwentu. W dalszej kolejności opisuje główne etapy budowy kościoła św. Marcina w Stanicy na kanwie dramatycznych dziejów zawieruchy napoleońskiej, posiłkując się kronikarskim zapisem ostatniej części odnalezionego dokumentu,…
Modelling of EM glass convection
2008
PurposeTo develop the mathematical model, which allows predicting the temperature and flow distribution of an opaque glass melt with the temperature‐dependent properties in case it is generated by electromagnetic and thermal convection. Analysis has been done for geometry of the model crucible with the immersed rod electrodes. Numerical analysis is used as a tool for finding out the parameters of the system, which allow getting desiderated homogeneity of temperature field by EM action.Design/methodology/approachANSYS CFX software is implemented for coupling of EM, thermal and HD processes in the modelled system. Usability of non‐inductive approximation is shown using a full harmonic analysi…
Modeling X-ray emission from stellar coronae
2008
By extrapolating from observationally derived surface magnetograms of low-mass stars we construct models of their coronal magnetic fields and compare the 3D field geometry with axial multipoles. AB Dor, which has a radiative core, has a very complex field, whereas V374 Peg, which is completely convective, has a simple dipolar field. We calculate global X-ray emission measures assuming that the plasma trapped along the coronal loops is in hydrostatic equilibrium and compare the differences between assuming isothermal coronae, or by considering a loop temperature profiles. Our preliminary results suggest that the non-isothermal model works well for the complex field of AB Dor, but not for the…
Opacity of young businesses: Evidence from rating disagreements
2008
Abstract A conventional wisdom in the contemporary corporate finance literature argues that small and medium-sized enterprises (SMEs) are informationally opaque. We use data from two credit information companies and in particular their disagreements over the creditworthiness of SMEs to study the empirical relevance of this often invoked assumption. Our panel data analysis shows that once unobserved firm-effects are controlled for, the disagreements (i.e., rating splits) are inversely related to the age of firms. We are not able to document such a robust relationship between the disagreements and the size of firms. This finding holds a lesson for empirical corporate finance researchers who n…

Making white spots disappear! Do minimally invasive treatments improve incisor opacities in children with molar-incisor hypomineralisation?
2022
BACKGROUND Children with molar incisor hypomineralisation (MIH) frequently seek aesthetic treatment for incisor opacities. Surprisingly few studies have evaluated the clinical success of such interventions. AIM To quantify the effectiveness of minimally invasive treatments in reducing enamel opacity visibility in children with MIH. DESIGN This in-vitro study used digital clinical images of 23 children aged 8-16 years with MIH who underwent microabrasion and/or resin infiltration for management of incisor opacities. Standard images were taken pre- and six-months post-treatment. Image software (Image-Pro Plus®V7) was employed to convert 24-bit RGB images to 16-bit grey-scale and 45% magnifica…
