For routine toxicity testing of composts and growing media, two different types of assays are usually applied. One approach is the use of growing trials in pots with various mixtures of the material. In extract-based tests, seeds are germinated in petri dishes and exposed to an exudate from the material to be tested. In this study, one of these methods, the Phytotoxkit microbiotest, was compare...
INTRODUCTION Bipolar disorder is an often disabling mental illness with a lifetime prevalence of 1%-2%, a high risk of recurrence of manic and depressive episodes, a lifelong elevated risk of suicide and a substantial heritability. The course of illness is frequently characterised by progressive shortening of interepisode intervals with each recurrence and increasing cognitive dysfunction in a ...
The High-Intensity-Discharge Lamps (HID), consisting of a broad range of gas discharge lamps, are notable for their high luminous efficacy, good color rendering, and long l ife. Metal halide lamps have the best combination of the above properties and are considered the most ideal light sources. Recently, there has been an emerging demand to replace the conventional halogen headlamps with the ne...
Evolutionary psychology seeks to synthesize fundamental principles of evolutionary biology with modern psychological theories, leading to testable hypotheses about the design of the human mind. This synthesis has proved useful in guiding the discovery of previously unknown phenomena, generating new predictions not produced by prior psychological models, and providing cogent theories about entir...
We have isolated an unusual heme peptide containing 27 amino acid residues and two heme groups from the variant heme protein, RHP, of the obligate photoanaerobe, Chromatium, strain D. This protein has been obtained in pure form and characterized previously (1) as a compound with molecular weight of 36,000 containing two functional heme groups. The heme peptide mixture, obtained by the peptic di...
Introduction Root hairs are specialized epidermal cells that play an important role in uptake of water and nutrients from rhizosphere. Each hair is a long, tubular, non-dividing cell characterized by tip growth, i.e. by deposition of new membrane and cell wall precursors at a cell-growing tip. Several root hair mutants have been isolated and genetically characterized in Arabidopsis thaliana (Pa...
For mechatronic systems, accurate frequency response data (FRD) can be obtained at low cost. Controller design techniques exist that can be applied directly to FRD, e.g. classical loop-shaping. However, loop-shaping can not guarantee that the designed controller is optimal in the sense of closed-loop norm speci cations, and the closed-loop pole locations cannot be computed directly. Besides ana...
Les travaux d’inventaire des perroquets sont rares au Cameroun. Pour inventorier les perroquets, déterminer leurs relations avec la végétation et menaces qu’ils rencontrent, 10 transects en lignes parallèles mesurant 2 km de long espacés 30 ont été choisis hasard dans zone d’étude (4°10 – 5°20 N ; 10°30 11°50 E), constituée du site Mbam Inoubou à prédominance savane Kim forestière. simultanémen...
The dyadic assessment framework – studying the strategies animals use to gather information during one-on-one contests, and how this drives contest behaviors outcomes can be fruitfully adapted intergroup contests: those between stable social-living groups.Heterogeneity among group members groups cohere make effective decisions are unique features of social living that add complexity assessment....
