Skolefritidsordning (SFO)/fritidshem har sitt ursprung i den nordiska modellen där utbildning ansågs vara en förutsättning för rättvisa, likvärdighet, social inkludering och demokratiskt deltagande. Den modellens enhetsskola kom skymundan under 2000-talet samband med konkurrensstatens kunskapsskolans inträde ett ökat fokus på nyttoorienterad kunskap, mätbara resultat individuellt ansvar. Mot ba...

Magnetic nanocomposites (NCs) are extremely appealing for a wide range of energy-related technological applications, specifically as building blocks next-generation permanent magnets. The design such nanostructures requires precise chemical synthesis methods, which will permit the fine-tuning magnetic properties. Here we present an in-depth structural, morphological and characterization ferrite...

Aims: The use of simple, low cost, high -efficiency extraction methods for sample preparation in the forensic toxicology has been considered. Nowadays, the chemometrics technique can be used to determine the influencing factors on the response to optimize extraction methods. The aim of this study was to design and optimize a dispersive liquid-liquid microextraction (DLLME) method for extraction...

Tlle paper describes the results of a comparison of two annotation systems for isstoslal;ion, the tone-based ToBI al)proach and the 1;unebased api)roach proposed by Systemic Functi(mal Grammar (SFO). The goal of this comparison is to detine a mapping between the two systems tbr the purpose of concept-to-speech generation of English. Since ToB: is widely used in Sl)eech synthesis and SFG is wide...

A new, simple, rapid, sensitive and environmentally friendly ultrasound-assisted emulsification dispersive liquid–liquid microextraction (UAE-DLLME) has been developed for trace nickel Ni(II) separation preconcentration in environmental samples prior to spectrophotometric determination. The proposed method based on using non-ionic water-soluble surfactant Triton X-114 (TX-114) as a disperser so...

Rice bran, a by-product of the rice milling process, has emerged as functional food and being used in formulation healthy drinks. However, bran is often contaminated with numerous mycotoxins. In this study, method to simultaneous detection aflatoxins (AFB1, AFB2, AFG1, AFG2), ochratoxin A (OTA), deoxynivalenol (DON), fumonisins (FB1 FB2), sterigmatocystin (STG), T-2 toxin, HT-2 diacetoxyscirpen...

Installation of distribution generation (DG) in the system gains many technical benefits. To obtain more benefits, location and size DG must be selected with appropriate values. This paper presents a method for optimizing based on enhanced sunflower optimization (ESFO) to minimize power loss system. In which, operational mechanisms original (SFO), mutation technique is added updating best plant...

For the analysis of trimethoprim medication in its pure form and pharmaceutical formulations, precise accurate microextraction techniques with UV-Vis measurement have been developed confirmed. In this study, LLE DLLME procedures were utilized for separation, pre-concentration, evaluation preparations by spectroscopy at 390 nm. The method was validated applied to formulations. Several experiment...

Dispersive Liquid-Liquid Microextraction / Thermal Lens Microscopy (DLLME/TLM) was developed as a new combination method for preconcentration and determination of Cd. Thermal Lens Microscopy is suitable for the determination of analyte after DLLME because of the low volume of the remained phase after DLLME and increasing of the enhancement factor for the nonpolar organic solvents. Some effe...
