During the past decade sugar alcohols have been extensively studied for thermal storage purposes. One of recent focuses research has in improving their heat charge and discharge rate by enhancing conductivity with different types additives. However, current literature shows a vast discrepancy measured values alcohols. This work presents an experimental study on seven The aim is to find out reas...

A total of 1752 strains of osrnophilic yeasts were isolated from honey and po]]ens. Fody-three strains Gf esmophilic yeasts produced po]yols, among whieh 6 strains produced erythritol in good yields. On the other hand, 52 osmophilic yeasts converted sucrose te fin]etooligosaccharides, among which 8 strains produced both extra and intracel]ular P-fructofuranosidase, which conyerted sucrose to fr...

Production of luteoskyrin, a hepatotoxin synthesized by Penicillium islandicum Sopp., was studied with various fermentation methods. Best results were obtained in static fermentations on glutinous rice at 30 degrees C. The isolated yield of pure luteoskyrin was approximately 400 mg per kg of rice. Also produced were skyrin, islandicin, iridoskyrin, rubroskyrin, chrysophanol, mannitol, and eryth...

Latent heat storage in district cooling systems (DCS) offers advantages such as energy efficiency, load shifting, and flexibility. It optimizes utilization by storing thermal during off-peak hours using it peak periods. This results cost savings, a reduced environmental impact, the enhanced reliability of system. In present study, novel system consisting phase-change material (PCM) tank coupled...

The title compound, C(15)H(28)O(4), was prepared by the condensation of pivalaldehyde with penta-erythritol. In the crystal, the two halves of the mol-ecule are related by a crystallographic twofold rotation axis passing through the central spiro-C atom. The two non-planar six-membered heterocycles both adopt chair conformations with the two tert-butyl groups both located in the equatorial posi...

The midge, Belgica antarctica Jacobs, is subjected to numerous environmental stressors during its 2-year life cycle on the Antarctic Peninsula, and in response it has evolved a suite of behavioral, physiological, and life-cycle modifications to counter these stressors, but thus far only a limited number of biochemical adaptations have been identified. In this study, we use a metabolomics approa...
