The anhamtonic effective pair potentials ~(u)=au~~+~u~/3!+yu~/4! in K& and CsBr have been investigated at room temperature by the EXAFS technique. In the parameter fitting, we have directly carried out the numerical integration of EXAFS function and evaluated the anharmonic effective pair potential. The Griineisen parameters y, were calculated from the obtained values of a and 6 as 1.65 for KBr...

The isobaric heat capacity of solid eutectic mixtures LiCl-KCl-CsCl, LiBr-CsBr and LiBr-KBr-CsBr was investigated from room temperature up to melting point. molar all under study found be close the additive sum that pure salts. accumulated is directly dependent on

We define and investigate a structure incorporating what is true, what is known and what is believed by a rational agent in models of the S4.2 logic of knowledge. The notion of KBR-structures introduced, provides a fine-grained modal analysis of an agent’s epistemic state, actually one that differentiates knowledge from belief and accounts for an agent without full introspective power (concerni...

Optical absorption spectra of KBr:Tl + (0.01mol%) single crystals shows A, B and C bands around 258, 220 and 210nm respectively. An additional absorption bands are observed in KBr-KI: Eu 2+ , Tl + (0.05, 0.01mol %) mixed crystals. These additional absorption spectra are attributed to the presence of Eu 2+ aggregates and complex centers involving both Eu 2+ and Tl + ions. Inclusion of Tl + ions ...

The knock-down, mortality and 'irritancy' effects of three synthetic repellents (DEET, IR3535 and KBR 3023) on Aedes aegypti (L) (Diptera: Culicidae) were evaluated in the laboratory in the absence of animal bait. Filter paper tests were carried out to assess the knock-down effect (KDt(50) and KDt(95)) and mortality (LC(50) and LC(95)) induced by each repellent. 'Irritancy' tests were carried o...

The gravity field maps of the satellite gravimetry missions GRACE (Gravity Recovery and Climate Experiment) Follow-On are derived by means precise orbit determination. key observation is biased inter-satellite range, which measured primarily a K-Band Ranging system (KBR) in Follow-On. satellites additionally equipped with Laser Interferometer (LRI), provides measurements lower noise compared to...

We conducted laboratory tests to assess the sensitivity to the insect repellent 1-piperidinecarboxylic acid, 2-(2-hydroxyethyl)-, 1-methylpropylester (known as KBR 3023 or Picaridin, trade name Bayrepel) of West African strains of the yellow fever mosquito Aedes aegypti and of malaria vectors of the Anopheles gambiae complex, in comparison with the standard repellent N,N-diethyl-3-methyl-benzam...
