BACKGROUND Nursing students have to deal with many different clinical and practical aspects of knowledge to become skilled professionals. Student perception may be considered an indicator of teaching quality, since positive perception of students is strictly related to their effective professional learning. The Clinical Learning Environment and Supervision plus Nurse Teacher (CLES+T) scale is c...

AIMS To determine roles of cortex lytic enzymes (CLEs) in Bacillus megaterium spore germination. METHODS AND RESULTS Genes for B. megaterium CLEs CwlJ and SleB were inactivated and effects of loss of one or both on germination were assessed. Loss of CwlJ or SleB did not prevent completion of germination with agents that activate the spore's germinant receptors, but loss of CwlJ slowed the rel...

Personal Learning Environments (PLEs) and Cloud Learning Environments (CLEs) have recently encountered a rapid growth, as a response to the rising demand of learners for multi-sourced content and environments targeting their needs and preferences. This paper introduces a semantic knowledge base that utilises a multi-layered architecture consisting of learning ontologies customized for certain a...

We present the results of comparing three different implementations of the microscopic diffusion process in the stellar evolution codes CESAM and CLES. For each of these implementations we computed models of 1.0, 1.2 and 1.3 M⊙. We analyse the differences in their internal structure at three selected evolutionary stages, as well as the variations of helium abundance and depth of the stellar con...

BACKGROUND A clinical learning environment is an "interactive network of forces within the clinical setting that influence the students' learning outcomes". International research indicates the Clinical Learning Environment and Supervision plus Nurse Teacher scale (CLES+T) as the gold standard to assess a good clinical learning environment. AIM This study aims to evaluate the psychometric pro...

Clostridial spore germination requires degradation of the spore's peptidoglycan (PG) cortex by cortex-lytic enzymes (CLEs), and two Clostridium perfringens CLEs, SleC and SleM, degrade cortex PG in vitro. We now find that only SleC is essential for cortex hydrolysis and viability of C. perfringens spores. C. perfringens sleC spores did not germinate completely with nutrients, KCl, or a 1:1 chel...

In the last few decades, scientists have learned how to manipulate the basic components of life, how to design biomolecular networks, how to evolve biomolecules with unique characteristics, and how to direct and control cellular processes at the molecular level. Using this knowledge as a foundation, it is theoretically possible to conceive of designing biological constructs, which we refer to a...
