Light, medium and heavy earmuffs’ amplitude frequency response was measured using transmission loss technique with a microphone placed in subject’s ear (MIRE – microphone in real ear) and on an artificial test fixture (ATF). Measurements were conducted in frequency range up to 9 kHz employing maximum length sequence (MLS). This method shows details of earmuffs’ amplitude frequency response, in ...

OBJECTIVE Pedicle screw fixation for spine arthrodesis is a useful procedure for the treatment of spinal disorders. However, instrument failure often occurs, and pedicle screw loosening is the initial step of a range of complications. The authors recently used a modified transpedicular polymethylmethacrylate (PMMA) screw augmentation technique to overcome pedicle screw loosening. Here, they rep...

We present the first testate amoeba-based palaeohydrological reconstruction from the Swiss Alps, and the first depth to the water table (DWT) calibration dataset for this region. Compared to existing models, our new calibration dataset performs well (RMSEP1⁄4 4.88), despite the length of the Faculty of Physics, Adam Mickiewicz University, Poznań, Poland water table gradient covered (53 cm). The...

We have used surgical gauze under the prepuceal skin as a pack in 20 cases prior to marking incision for circumcision. The prepuceal adhesions were first dissected and seperated. The method allows a stable, well-supported prepuceal surface for marking incisions and avoids injuries to the glans. Because the prepuceal surface is taut and stable, hemostasis is easier and quicker and the operating ...

Surgical technique of total laryngectomy is well presented in many surgical textbooks. Essentially, it has remained the same since Gluck an Soerensen in 1922 described all its details. Generally, it stresses the U shape skin incision with releasing laryngeal structures and removing larynx from up to down. Further, pharyngeal reconstruction is performed with different kinds of sutures in two or ...

Purpose The aim of the study was to quantify the isolated tear film adhesion error in a Goldmann applanation tonometer (GAT) prism and in a correcting applanation tonometry surface (CATS) prism. Methods The separation force of a tonometer prism adhered by a tear film to a simulated cornea was measured to quantify an isolated tear film adhesion force. Acrylic hemispheres (7.8 mm radius) used a...

The objective of this paper is to assess increase and decrease of forest area and estimate shrub encroachment between 1997 and 2002 in open mire land using CIR-aerial images, DSMs derived from it and LiDAR data. The present study was carried out in the framework of the Swiss Mire Protection Program, where changes of forest area are a key issue. The study area is located in the Pre-alpine zone o...

AIM to develop a modification to hybrid phacoemulsification (PE) that would involve the use of femtosecond laser. MATERIAL AND METHODS Modified hybrid PE was performed in 225 patients (267 eyes) with grade II-IV lens nuclei in terms of their density. Conventional PE was performed in 237 patients (278 eyes). RESULTS By utilizing the suggested technique of PE, one can avoid certain problems o...
