Taxi service is an important mode of modern public transportation. However, operated by a large number of selfcontrolled and profit-driven taxi drivers, taxi systems are quite in efficient and difficult to analyze and regulate. While there has been some work on designing algorithms for improving taxi system efficiency, the state of the art algorithm, unfortunately, cannot scale up efficiently. ...

enterococci are gram positive and catalase- negative cocci that are found in the gastrointestinal tract of mammals and birds, and are readily isolated from soil, surface and waters. the aim of this study was to discriminate between enterococcus isolates based on repetitive element sequence based –pcr (rep-pcr) with the boxa2r primer and their antibiotics profile. enterococci isolates were obtai...

soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. fifty soil samples were collected from various areas of forests and farmyards at golestan province in the north part of iran to determine the prevalence of keratinophilic fungi and dominant species. a total of 357 fungal colonies including 13 genera ...

according to changes in the surface of respiratory epithelial cells and host immunity as well as virulence of hospital acquired pathogens, oropharyngeal colonization enhance in hospital admitted patients. patient admission in hospital, due to changes of oropharyngeal flora and colonization of virulent germs such as staphylococcus aureus and gram negative bacilli can be a serious problem for dev...

introduction: nosocomial infections affect nearly 10% of hospitalized patients. the majority of nosocomial infections are transmitted by contact, primarily by hands of health care workers. the micro-organisms on the hand can be divided into transient, resident and infectious flora. transient flora is the main cause of nosocomial infection which acquired primarily by contact and loosely attached...

background: normal bacterial flora of the conjunctiva, which inhibits growth of opportunistic organisms, has an important role in the prevention of ocular infections. if resident flora is inhibited by disease or long-term application of antibiotics, opportunistic pathogens overgrow, leading to disease. objectives: the aim of this study was to investigate the effects of ophthalmic chloramphenico...

conclusions the results showed that although the human gut microbiome plays a pivotal role in health in a normal concentration, fluctuation in their number (increase or decrease) is a possible factor in the appearance of major diseases. context the composition and function of the gut microbiota develop with their host from birth. the human microbiome, especially the gut microbiota, plays a crit...

The Italian endemic vascular flora is composed of 1,286 specific and subspecific taxa. From the critical analysis of "Chrobase.it", 711 of them (about 55%) have been studied from a karyological point of view. These taxa belong to 52 out of 56 families and 204 out of 284 genera. These data suggest that endemic species are more studied than the flora as a whole. Mean chromosome number for Italian...
