background and aims. there are many edentulous people with severely resorbed residual ridges and non-resilient lining mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. the aim of this study was to evaluate the effe...

to evaluate the effect of intrauterine cephapirin on treatment of endometritis 39 holstein dairy cows that affected with postpartum endometritis were selected and randomly assigned to two experimental designs. in experiment 1, 6 out of 14 cows were 25 to 30 days after parturition were treated by intrauterine oxytetracycline. another 8 cows were treated by intrauterine cephapirin (metri-care). i...

background and aims. reactive hyperplasias (rhs) are common oral mucosal lesions caused by irritation of the mu-cosa. the aim of this study was to evaluate the frequencies of various types of oral rhs in a university clinic. materials and methods. oral rh cases, undergone biopsy in a four-year period, were studied retrospectively. data including age and gender as well as the location and clinic...

Duration Calculus (DC) is a real-time logic with measurement of duration of propositions in observation intervals. It is a highly expressive logic with continuous time behaviours (also called signals) as its models. Validity checking of DC is undecidable. We propose a method for validity checking of Duration Calculus by reduction to a sampled time version of this logic called well sampled Inter...

The aim 1. To examine the prevalence of chronic rhinitis among glassblowers (experimental group) and control group based on objective findings at nasal mucosa. 2. To examine using appropriate statistical methods whether or not chronic rhinitis have higher prevalence in group of glassblowers. 3. To examine whether or not prevalence of chronic rhinitis depends on duration of exposure to noxious f...

Long-duration consistently Escherichia coli O157:H7 culture-positive cattle were euthanized and necropsied. Tissue and digesta from along the gastrointestinal tract (GIT) were cultured for the bacteria and examined histologically for lymphoid character. E. coli O157:H7 was detected only at the rectoanal junction mucosa and not at any other GIT location.

oral lichen planus (olp) is a chronic inflammatory disease of the oral mucosa which is considered by the world health organization (who) as a premalignant condition. one step in malignant development is so called epithelial mesenchymal transition (emt), a process whereby epithelial cells acquire mesenchymal characteristics. a factor known to induce emt is the transforming growth factor-β (tgf-β...

We generate space-time coupled attosecond pulse trains with a 1.8 μm wavelength laser pulse using the ‘attosecond lighthouse’ technique. We show low divergence, spatially well-separated beamlets from low ionization potential gas media. We also find that there is little long trajectory contribution—only the short trajectory contribution is clearly visible for any beamlet. These results open a ne...

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
