Constraints on an annihilation signal from a core of constant dark matter density around the Milky Way center with H.E.S.S.
(American Physical Society, 2015)
An annihilation signal of dark matter is searched for from the central region of the Milky Way. Data acquired in dedicated on-off observations of the Galactic center region with H.E.S.S. are analyzed for this purpose. No ...
Effects of host injury on susceptibility of marine reef fishes to ectoparasitic gnathiid isopods
(Springer, 2018)
The importance of the role that parasites play in ecological communities is becoming increasingly apparent. However much about their impact on hosts and thus populations and communities remains poorly understood. A common ...
A comparison of the mathematical knowledge and skills of first-year student cohorts from a transmission and an outcomes-based curriculum
(Taylor & Francis, 2015)
The traditional transmission-based school curriculum in South Africa has been replaced by an outcomes-based school curriculum since 1998. In this article we report on a comparative study on the mathematical knowledge and ...
Factors that affect the accuracy of text–based language identification
(Elsevier, 2012)
The classification accuracy of text-based language identification depends on several factors, including the size of the text fragment to be identified, the amount of training data available, the classification features and ...
Simple forms and invariant subspaces of H-expansive matrices
(Elsevier, 2015)
In this paper we consider a simple form for pairs of matrices (A,H)(A,H), where H is a real symmetric invertible matrix, and A is a real H -expansive matrix, that is, ATHA−HATHA−H is positive semidefinite. For such pairs ...
Reaction of a fluorine atom with methanol: potential energy surface considerations
(American Chemical Society, 2015)
There are several experimental studies of the F + CH3OH reaction but very little in the way of reliable theory. Here reported are aug-cc-pVQZ CCSD(T) computations for two different reaction pathways. The more exothermic ...
Effect of ozone on photosynthesis and seed yield of sensitive (S156) and resistant (R123) Phaseolus VulgarisL. genotypes in open-top chambers
(Springer, 2013)
Rising tropospheric ozone (O3) concentrations have been identified as a significant threat to crop production. In the present study two snap bean (Phaseolus vulgaris L.) genotypes with known difference in sensitivity to ...
Spectral, thermal stability and antibacterial studies of copper, nickel and cobalt complexes of N-methyl-N-phenyl dithiocarbamate
(Taylor & Francis, 2015)
Copper(II), cobalt(II) and nickel(II) bis(N-methyl-N-phenyl dithiocarbamate) complexes having the general
formula [M{S2CN(MePh)}2] (where M = Cu, Co and Ni) have been prepared and characterized
by spectral and thermal ...
Investigating the effectiveness of mandatory integration of health impact assessment within environmental impact assessment (EIA): a case study of Thailand
(Taylor & Francis, 2018)
The effectiveness of the integration of health impact assessment (HIA) and environmental impact assessment (creating an environmental and health impact assessment’ (EHIA) process) is investigated, drawing on an example of ...
Modeling the pulse profiles of millisecond pulsars in the second LAT catalog of γ-ray pulsars
(AIP, 2012)
Significant γ-ray pulsations have been detected from ∼40 millisecond pulsars (MSPs) using 3 years of sky-survey data from the Fermi LAT and radio timing solutions from across the globe. We have fit the radio and γ-ray pulse ...
