Šiame darbe tiriami polihidroksiliai alkoholiai sacharozė bei glicerolis, kaip ligandų alternatyvos cheminio variavimo sistemoms su reduktoriumi formaldehidu. Tai yra ekologiškos, biologiškai lengvai suyrančios medžiagos. Šiame darbe atlikti šių medžiagų kompleksų pusiausvyros skaičiavimai, eksperimentai parodantys sacharozės bei glicerolio praktinį pritaikomumą cheminio variavimo sistemose. Ultragarso poveikio cheminėms sistemoms dėsningumai dar nėra vienareikšmiškai ištirti ir suprasti.

Abstract:

This work investigates polyols – glycerol and sucrose – as an alternative ligand for electroless copper plating systems with reducer formaldehyde. Natural polyols are environmentally friendly, easily bio-degradable materials, but has not been studied enough for suitability for copper plating systems. In order to increase of the efficiency, the electroless copper plating was investigated in ultrasonic milieu to observe how ultrasound impacts the copper plating rate and properties of the obtained coatings. Studies have shown that sucrose and glycerol can be used as ligands in solutions for elect

Abstract:

The work is focused on the analysis of data on sugar composition of honey coming from beekeepers in the Czech Republic. The database includes a number of years and several hundred locations. The aim is to test the hypothesis that sucrose content in honeys vary in individual years in connection with the course of the weather, especially the sufficiency or deficiency of rainfall, so that in rare cases it can even unadulterated honeys sucrose content exceed the limit specified standard. It will formulate recommendations for action at the findings of the high sucrose content of genuine honeys to p

Este trabajo de tesis constituye un recorrido por la trayectoria artística y una propuesta de interpretación de la obra de la pintora Olga Sacharoff (Tiflis 1881 - Barcelona 1967) quien, aparte de algunos textos en catálogos de exposiciones, todavía no contaba con un estudio más completo. A comienzos del siglo XX la artista se trasladó a París donde, hasta la Segunda Guerra Mundial, desarrolló una pintura enmarcada en los lenguajes de vanguardia. Atendiendo a los espacios donde expuso y a los círculos artísticos que frecuentó, este trabajo -a partir de la documentación encontrada-, propone

Abstract:

Invert syrup is a liquid sweetener, which is produced by sucrose hydrolysis to form fructose and glucose. Important qualitative parameter of invert syrup is the sucrose inversion – weight percentage of invert sugar (sum of fructose and glucose) in invert syrup dry mass. This diploma thesis presents a possibility of sucrose inversion determination by polarimetry in combination with refractometry in invert syrups of 70–78 % dry mass produced at 80 °C and pH 2,4. New relationship describing the sucrose inversion as a function of polarization and refractometric dry mass was determined. The results
