Early-phase transmission of Yersinia pestis by cat fleas (Ctenocephalides felis) and their potential role as vectors in a plague-endemic region of Uganda In recent decades, the majority of human plague cases (caused by Yersinia pestis) have been reported from Africa. In northwest Uganda, which...
(Ar) may be used as a carrier gas. In some cases, oxygen (O2) may also be included as carrier. The etch rate and the etch selectivity depend on the etchant gas, etchant flow rate, power, pressure, and substrate temperature. The buffer layer330may serve as an etch stop layer to ...
of thermal expansion (CTE) variations of a few ppb/° C. In some cases, striae have been found to impact surface finish at an angstrom root mean rms level in reflective optic elements made from the glass. Extreme ultraviolet lithographic elements require finishes having a very low rms level....
Extreme Contractions on Real Hilbert Spaces - Grzaslewicz - 1982 () Citation Context ...aracterise the extreme contractions from `p2 to ` q 2 and obtain their closure. The technique used is similar to [34]. In the process, we reestablish relevant special cases of the results obtained in...
(respectively) during three consecutive years when replicated in the lab, such that no sex ratio biases were detected that could be attributable to year-to-year differences in the source of eggs or incubator performance (Chi2(df=1) > 3.84, P > 0.05 in all cases), all other ...
Tests were performed with uniform limestone gravels of different sizes. Materials M1 and M2 had median sizes, D50, of 12.6 and 35.0 mm, respectively. The coefficients of uniformity, Cu, were 1.55 and 1.58, respectively. The porosity of the packed material was n=0.41 in both cases (void ra...
a. In extreme cases, people suffering from CTE have even committed suicide or homicide. The majority of people who develop these issues are athletes who participate in popular high-impact sports, especially football. Although new sports regulations and improvements in helmet technology can help protec...
The acquired mathematical models are generalized for the cases of vector derivatives of higher orders. The presented models are of systematic nature and are universal, i.e., they can be applied in formation of any polynomial spline curves given extreme vector derivatives. The paper provides a ...

12 March 2016 Abstract: Operation of an α-hemolysin nanopore transduction detector is found to be surprisingly robust over a critical range of pH (6–9), including physiological pH = 7.4 and polymerase chain reaction (PCR) pH = 8.4, and extreme chaotrope concentration, including 5 M urea. ...
