Bacterial spores are robust and dormant life forms with formidable resistance properties, in part, attributable to the multiple layers of protein that encase the spore in a protective and flexible shield. The coat has a number of features pertinent to the emerging field of nanobiotechnology including self-assembling protomers and the capacity for engineering and delivery of foreign molecules. T...

This article deals with the development of an original sample preparation method for transmission electron microscopy (TEM) using focused ion beam (FIB) micromachining. The described method rests on the use of a removable protective shield to prevent the damaging of the sample surface during the FIB lamellae micromachining. It enables the production of thin TEM specimens that are suitable for p...

Introduction: To present and assess a newly designed autoclavable, reusable tube shield for an endotracheal tube (ETT) during laser laryngeal surgery.   Materials and Methods: This study included patients scheduled for endolaryngeal laser surgery. A carbonated stainless-steel hemisphere shield (~1.5×0.6 mm) connected to a silk thread passing through a hole in its middle near upper edge was ...

Daguerreotypes are sharply defined, highly reflective, one-of-a-kind photographs on silver-coated copper plates, packaged behind glass and kept in protective cases. Introduced in 1839 by Louis-Jacques-Mandé Daguerre, the daguerreotype process was the first commercially successful photographic process, and is distinguished by a remarkable clarity of pictorial detail. Daguerreotypes were popular ...

The present study aimed to investigate the interaction among grade dropping and reflective thinking abilities of the participants and to also check if action research enhances learners’ reflective thinking. A cyclic action research was run for 8 sessions. Kember et al.’s (2010) reflective thinking questionnaire and three in-term quizzes were administered. Students also made questions based on t...

Dentists are one of the professions most at risk infection transmission because dental care potentially produces many infectious aerosols for bacterial transmission. Using personal protective equipment and aerosol suction that meets standards dentists is vital to prevent cross-infection in patients practice. This study aims determine effect distance on orthodontic patient bracket brushing proce...

The present study is aimed at investigating the relationship among Iranian EFL teachers’ reflective teaching, reflective thinking and classroom management ability. To this purpose, 102 male and female EFL teachers, aged between 25 and 40, with different academic background who were teaching at different levels, were chosen to fill in three questionnaires on reflective thinking, reflective teach...

The aerobic gram negative bacterium Pseudomonas aeruginosa is an opportunistic pathogen responsible for life threatening acute and chronic infections in humans. As part of chronic infection P. aeruginosa forms biofilms, which shield the encased bacteria from host immune clearance and provide an impermeable and protective barrier against currently available antimicrobial agents. P. aeruginosa ha...
