INTRODUCTION In this in-vitro study, we aimed to investigate the predictability of the expected amount of stripping using 3 common stripping devices on premolars. METHODS One hundred eighty extracted premolars were mounted and aligned in silicone. Tooth mobility was tested with Periotest (Medizintechnik Gulden, Modautal, Germany) (8.3 ± 2.8 units). The selected methods for interproximal ename...

The cross sections for the stripping of two correlated nucleons from light and medium-mass nuclei are considered. Such reactions are of interest both as a means for populating and identifying low-lying excited states of very exotic nuclear species and as a potential direct spectroscopic probe of two-nucleon correlations in such systems. A calculation scheme that combines the full shell model tw...

Two experiments were conducted to compare techniques to maximise the amount of milk harvested mechanically from Poll Dorset ewes. The treatments were double cupping, machine stripping, Sagi hook, a negative control (no extra stripping applied) and a positive control (residual milk withdrawn after injecting 5 IU of oxytocin). In the first experiment it was shown that the amount of milk collected...

The relative importance of neutron transfer and breakup process in reaction around Coulomb barrier energies have been studied for the $^{7}$Li+$^{124}$Sn system. Coupled channel calculations performed to understand one stripping pickup cross sections along with systematics two striping $^7$Li projectile on several targets show an approximate universal behaviour that explained by a simple model....

Superficial temporal artery-middle cerebral artery (STA-MCA) has been used for the treatment of occlusive cerebrovascular disease including moyamoya disease. The effect of STA-MCA bypass depends not only on the patency of anastomosis, but also on integrity and functional capacity of the donor artery. In the present prospective study, we investigated the effect of extensive stripping STA adventi...

OBJECTIVES Saphenous nerve injury is the most common complication after surgical treatment of varicose veins. The aim of this study was to establish its frequency at great saphenous vein long stripping when four methods of surgery were applied. METHODS Eighty patients were divided into four groups depending on different stripping methods. Sensory transmission in saphenous nerve and sensory pe...

The main objective of this study is to investigate the personal or area exposure of organic solvents during paint stripping and paint spraying. Three aircraft paint stripping/spraying workplaces in Taiwan were selected, and the Council of Labor Affairs and NIOSH recommended sampling/analytical methods used in this study. Activated charcoal tubes were used to investigate the personal and area ex...

OBJECTIVES To compare the long-term results of stripping vs. haemodynamic correction (Ambulatory Conservative Haemodynamic Management of Varicose Veins, CHIVA) in the treatment of superficial venous incompetence resulting in chronic venous disease (CVD). DESIGN Randomised comparative trial. PATIENTS 150 patients affected by CVD, CEAP clinical class 2-6, were randomised to saphenous strippin...
