OBJECTIVE This study aimed to compare the effects of two different perfusion techniques: conventional cardiopulmonary bypass and miniature cardiopulmonary bypass in patients undergoing cardiac surgery at the University Hospital of Santa Maria--RS. METHODS We perform a retrospective, cross-sectional study, based on data collected from the patients operated between 2010 and 2013. We analyzed th...

Advanced thermoelectric microdevices integrated into thermal management packages and low power, electrical power source systems are of interest for a variety of space and terrestrial applications. By making use of macroscopic film technology, microgenerators operating across relatively small temperature differences can be conceptualized for a variety of high heat flux or low heat flux heat sour...

Considerable interest has been focused on miniature biofuel cells (BFCs) because of their portability and possibility to be implantable. Origami devices with hollow channels will provide novel insight into the assembly methods of miniature BFCs. Herein a miniature origami BFC has been fabricated from a MnO2-graphite flake consumed solid-state cathode. For further practical applications, miniatu...

Stingless bees may produce both large queens and "miniature" queens, but the adaptive significance of this is uncertain. Using biometry and statistical analysis we determined the proportion of miniature queens in Plebeia remota that were either mated (14%) or virgin (45%). Mated queens were mostly normalsized which indicated that they were more successful. Nevertheless, the presence of miniatur...

The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...

This thesis focuses on the design and characterisation of miniature bioreactors and evaluates their potential as a scale-down device for microbial cultivation processes. Miniature bioreactors, such as the one detailed in this work, have been developed by many research groups and companies, and seek to increase throughput at the early stages of bioprocess development. Power input was measured in...

ultrasonography is a relatively easy, safe and non-invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations. as there has been no collated study undertaken on the normal measurements of ocular structures in caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye ...

hojatt-ol hagh hakim abolfath-e omar ibn-e ebrahim known as khayyam or khayyami, was a philosopher, mathematician, astrologer, and poet of late fifth-early sixth century a.d. for long he was famous for his scientific features, however, later on his stanzas, were introduced to the world, the west in particular, through the translations provided by the nineteenth century british poet fitzgerald. ...
