background: to identify the fasciolid species by morphometric and molecular methods in zanjan, north­west of iran. methods : adult fasciola worms (n=584) were obtained from cattle and sheep in zanjan slaughterhouse in 2007. living flukes were washed, then worms' images were taken by 3ccd camera and finally apical zone of each worm was obtained. morphometric values such as body length, body widt...

The purpose of this study was to investigate the influence of superhydrophilic treatments of titanium on the behavior of osteoblastlike cells. Superhydrophilic specimens were prepared with sandblast and acid-etching (DW), oxygen plasma (Plasma) and ultraviolet light (UV), and were stored in distilled water for 3 days immediately after these treatments. Specimens stored in air for 3 weeks were u...

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The sp...

Thirty-four calf and five infant fecal specimens were tested for the neonatal calf diarrhea virus (NCDV) and for the reovirus-like infantile diarrhea agent; respectively. The procedures used were the fluorescent virus precipitin test and immune electron microscopy. Fourteen of the calf stools contained detectable NCDV, and four of the five infant stools contained the reovirus-like human agent. ...

The precise occurrence of Opisthochis viverrini infection in humans, who were positive for Opisthorchis-like eggs in a stool examination, was determined using the potassium permanganate staining method. In the 68 specimens examined, there were more individual O. viverrini eggs (38.24%) than singular Haplorchis taichui eggs (29.41%). One-fourth of the total specimens contained a mixed infection ...

range of techniques Hooke could not possibly have imagined. Some of these techniques, like transmission electron microscopy and atomic force microscopy, can resolve individual atoms, while others, like environmental scanning electron microscopy, can image biological specimens at high resolution in something close to their natural state. As well as providing incredibly detailed images, modern mi...

With the shift during the 1980s from a human-great ape ultimately to an orangutan-(gorilla-(human-chimp)) theory of relatedness, the search for chimpanzee-like features in early hominids intensified. Reconstructions of early hominids became caricatures of chimpanzees, not only in soft tissue features (e.g. the nasal region), but in supposed bony structures (e.g. an anteriorly and especially sup...

Museum technology is perpetually changing due to current requirements and added inventions for our comfort and furbished display of specimens. Hence numerous methods of specimen preservation have been put on trial by diverse people in the medical feld as are the inventions. But only few have caught people's interest and are popularized today. This part provides unique insights into specialized ...

In a recent article, Alex Levine raises a paradox. It appears that, given some relatively uncontroversial premises about how a species term comes to refer to its species, a type specimen belongs necessarily and contingently to its species. According to Levine, this problem arises if species are individuals rather than natural kinds. I argue that the problem can be generalized: the problem also ...
