a growing body of research has indicated that students of esl/efl are reticent and unwilling to be engaged in oral activities in english lessons. communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. however, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. the pres...

We present a theory of spino¤s in which workers generate productive ideas and possess private information concerning their quality. Because quality is privately observed, by the standard adverse-selection logic, the market can at best o¤er a price that re‡ects the average quality of ideas sold. This gives the holders of above-average-quality ideas the incentive to spin o¤. We show that only wor...

With flexure-based micro-positioning stages (MPSs) being in high demand for high-precision applications, the performance and cost of MPSs are two issues that urgently need to be addressed. In addition, current developed toward complex spatial configurations, which further precludes monolithic fabrication. To address aforementioned issues, modular using designed standardized modules introduced t...

Introduction. Mucopolysaccharidoses (MPSs) represent a group of rare lysosomal storage diseases, associated with the decline in life expectancy and impairing it’s quality. Despite prolonged evaluation effectiveness pathogenic therapy, patient-reported outcomes are poorly defined. The aim study. To describe impact enzyme-replacement therapy (ERT) on quality MPS children, using parent-completed v...

Our recent article opened a valuable discussion on the safety of miniaturized perfusion systems (MPSs) with respect to the risk of gaseous microemboli (GME) [1, 2]. We would like to comment on this. Although the clinical advantages of MPSs are well known, it is still important to focus on avoiding possible side effects in order to increase patient safety [3]. In our study, we observed excessive...

Abstract. In this work, new particle formation events (NPFs) occurring at two locations in southern Italy, the urban background site of Lecce (ECO station) and coastal Lamezia Terme (LMT station), are identified analyzed. The study aims to compare properties NPF sites, located 225 km away from each other characterized by marked differences terms emission sources local weather dynamics. Continuo...
