An experimental and theoretical study was undertaken for three ether glycols (mixtures of isomers). The present paper, being the first part a complex study, reports using static apparatus, namely, vapor–liquid equilibria dipropylene glycol methyl (DPM), n-butyl (DPnB), propylene (PnB), their pseudo-binary mixtures composed (PnB + DPM), (DPM DPnB), aqueous solutions each ether. explored temperat...

An experimentally obtained polarization curve for the hydrogen evolution reaction on silver in a 0.5 mol dm−3 solution was investigated using an electrochemical curve technique named the differential polarization method (DPM). The exchange current density estimated by the Tafel extrapolation method (TEM) and the DPM were compared and assessed from points of simple and more accurate handling. It...

Pavlovian olfactory learning in Drosophila produces two genetically distinct forms of intermediate-term memories: anesthesia-sensitive memory, which requires the amnesiac gene, and anesthesia-resistant memory (ARM), which requires the radish gene. Here, we report that ARM is specifically enhanced or inhibited in flies with elevated or reduced serotonin (5HT) levels, respectively. The requiremen...

The aim of the study was to conduct an analysis of the main symptoms of deep pectoral myopathy (DPM) in broiler chickens, which is manifested by changes in colour and texture of the affected muscle. The research was conducted on Ross508 chicken broilers, at an age of 35-42 d. The lesions were assessed through macroscopic inspection, using colour parameters as well as texture analysis. Furthermo...

BACKGROUND It is a challenge to assess children's dietary intake. The digital photographic method (DPM) may be an objective method that can overcome some of these challenges. OBJECTIVE The aim of this study was to evaluate the validity and reliability of a DPM to assess the quality of dietary intake from school lunch sandwiches brought from home among children aged 7-13 years. DESIGN School...

Dual-task practice has been previously shown to enhance motor learning when both primary and secondary tasks engage similar cognitive processes. In the present study, participants practiced a finger sequence task with the non-dominant hand under a single-task condition (i.e. without a probe task) or a dual-task condition in which a probe choice reaction time (CRT) task was presented during the ...
