Microwave-Assisted One-Pot Synthesis of Novel Polyarylpyrrole Derivatives of Expected Anticancer Activity
(Journal article, 2017)An efficient synthesis of Novel pyrrolederivatives was achieved via solventless reaction of chalcones 1(a-e) with different aldehydes 2(a-e) and ammonium acetate in the presence of sodium cyanide in one-pot under microwave ... -
Mimicking orchids lure bees from afar with exaggerated ultraviolet signals
(Peer reviewed; Journal article, 2023-01)Flowers have many traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well-known for attracting bees at close proximity (e.g., <1 m). While striking UV signals have been thought to ... -
A multiple-source air quality control model achieving a standard, defined by a vector-valued function
(Conference object, 2009-07)Earlier papers by Gustafson, Kortanek, Sweigart and others describe models for controlling air pollution, consisting of chemically inert pollutants like sulphur dioxide. It was assumed that the concentration contributions ... -
Natural peptides with antioxidant activity from Atlantic cod and Atlantic salmon residual material
(Journal article; Peer reviewed, 2016-03)Summary. Water-soluble peptides/proteins with molecular weight below 10 kDa were isolated from residual material of cod (liver, skin, and cod mix i.e. skin, frames, and viscera), and salmon (skin, and salmon mix i.e. skin, ... -
Note on the invariant classification of vacuum type D spacetimes
(Journal article; Peer reviewed, 2009-12)We illustrate the fact that the class of vacuum type D spacetimes which are I-non-degenerate are invariantly classified by their scalar polynomial curvature invariants. -
On computational linear semi-infinite programming

On high-order perturbative calculations at finite density
(Journal article; Peer reviewed, 2017-02)We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ... -
On the algebraic classification of pseudo-Riemannian spaces
(Journal article; Peer reviewed, 2011-12)We consider arbitrary-dimensional pseudo-Riemannian spaces of signature (k, k + m). We introduce a boost-weight decomposition and define a number of algebraic properties (e.g. the Si- and N-properties) and present a ... -
On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017-02)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ... -
Optimization of acid catalyzed transesterification of jatropha and rapeseed oil with 1-butanol
(Peer reviewed; Journal article, 2014-08)The acid catalyzed transesterification of rapeseed and jatropha oil with 1-butanol was studied by varying temperature, reaction time, butanol/triglyceride ratio and the amount of sulfuric acid. A full factorial design ... -
Photochemical oxidative cyclisation of stilbenes and stilbenoids : the Mallory-reaction
(Journal article; Peer reviewed, 2011-06-14)After Mallory described in 1964 the use of iodine as catalyst for the photochemical cyclisation of stilbenes, this reaction has proven its effectiveness in the synthesis of phenanthrenes, other PAHs and phenacenes with a ... -
Photochemical synthesis of chrysenols
(Peer reviewed; Journal article, 2008-08)Chrysenols are formed together with other metabolites when chrysene is metabolized in living organisms. The principal metabolites are needed as pure compounds for reference materials and standards to study various aspects ... -
PLATINUM SENSITIVE 2 LIKE impacts growth, root morphology, seed set, and stress responses
(Journal article; Peer reviewed, 2017-07)Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes ... -
Primordial Gravitational Waves with LISA
(Journal article; Peer reviewed, 2017)Primordial Gravitational Waves are the next target of modern cosmology. They represent a window on the early Universe and the only probe of the physics and microphysics of the inflationary period. When the production of ... -
Pseudo-Riemannian VSI spaces
(Journal article; Peer reviewed, 2011)In this paper we consider pseudo-Riemannian spaces of arbitrary sig- nature for which all of their polynomial curvature invariants vanish (VSI spaces). We discuss an algebraic classification of pseudo-Riemannian spaces ... -
Pseudo-Riemannian VSI spaces II
(Journal article; Peer reviewed, 2012)In this paper we consider pseudo-Riemannian spaces of arbitrary signature for which all of the polynomial curvature invariants vanish (VSI spaces). Using an algebraic classification of pseudo-Riemannian spaces in terms of ... -
Regiospesific synthesis of dimethylphenanthrenes
(Peer reviewed; Journal article, 2017-05)The dimethylated phenanthrenes 2,3-dimethylphenanthrene (4a), 2,7-dimethylphenanthrene (4b), 2,6-dimethylphenanthrene (4c) and 1,7-dimethylphenanthrene (4d) have been prepared in gram-quantities by a short sequence of ... -
A review of the monophyly and composition of the Bengaliinae with the description of a new genus and species, and new evidence for the presence of Melanomyinae in the Afrotropical Region (Diptera, Calliphoridae)
(Book; Peer reviewed, 2011)Mafikengia ciliata gen. nov., sp. nov. is described from South Africa and assigned to the subfamily Bengaliinae of the Calliphoridae. It is recognisable by its small size (4 mm), mostly yellow body, and a number of peculiar ... -
Revision of the Afrotropical species of the Bengalia peuhi species-group, including a species reassigned to the B. spinifemorata species-group (Diptera, Calliphoridae), with notes on the identity of Ochromyia petersiana Loew, 1852 (Diptera, Rhiniidae)
(Book; Peer reviewed, 2012)Eleven Afrotropical species of Bengalia Robineau-Desvoidy, ten in the Bengalia peuhi species-group and one reassigned to the Bengalia spinifemorata species-group, are revised. The male genitalia of all, and the ovipositor ... -
