Background The changes in corneal biomechanical properties after LASIK remain an unknown but important topic for surgical design and prognostic evaluation. This study aims to observe the postoperative corneal biomechanical properties one month after LASIK with amount of corneal cutting (ACC) greater than 50% of the central corneal thickness (CCT). Methods FS-LASIK was performed in 10 left rab...

OBJECTIVE To examine the effects of the length and timing of nighttime naps on performance and physiological functions, an experimental study was carried out under simulated night shift schedules. METHODS Six students were recruited for this study that was composed of 5 experiments. Each experiment involved 3 consecutive days with one night shift (22:00-8:00) followed by daytime sleep and nig...

Three monoclonal antibodies MT1, L60 (Leu-22), and DF-T1, were reported independently as recognising human T cells in routinely processed, paraffin wax embedded tissue. The present study was performed to compare these three reagents in terms of their immunocytochemical reactions and target molecule(s). On Western blotting of white cell extracts the three antibodies reacted with antigens of the ...

In total, 20 multiparous Holstein-Friesian dairy cows received one of four diets in each of four periods of 28-day duration in a Latin square design to test the hypothesis that the inclusion of lucerne in the ration of high-yielding dairy cows would improve animal performance and milk fatty acid (FA) composition. All dietary treatments contained 0.55 : 0.45 forage to concentrates (dry matter (D...

A collection of typical examples shows the exotic behaviour of numerical methods when applied to singular perturbation problems. While standard meshes are used in the first six examples, even on layer-adapted meshes several surprising phenomena are shown to occur. AMS subject classification (2000): 35 L10, 35 L12, 35 L60

This paper examines whether receipt of an RSA grant has a causal impact on plant TFP. To tackle the problem of self-selection into the treatment group, propensity score matching is employed. In order to control for the endogeneity of other variables in the model, estimations are performed using the system GMM estimator. The results show that for low technology manufacturing, receipt of an RSA g...

This paper argues that multinational companies can impact positively on the survival of plants in the host country through technology spillovers. We study this effect empirically by estimating a Cox proportional hazard model on plant level data for Irish manufacturing. Our results show that, ceteris paribus, the presence of multinationals has a life enhancing effect on indigenous plants in high...

Theoretical calculations for magnetic moments of T=O collective states in N = 2 nuclei are compared with recent experimental results. The J"= 2 + and 3 states considered all have 0.49 < gtheor < 0.5 1 if the wavefunctions have pure T= 0 isospin. Isospin mixing increases the calculated l60 3-g factor by 9%, consistent with experiment, but has a much smaller effect on the 2' states. A reported ne...
