Analyses of phase change materials’ efficiency in warm-summer humid continental climate conditions
2017
The usage of phase change materials (PCMs) is a way to store excess energy pro- duced during the hot time of the day and release it during the night thereby reducing the overheating problem. While, in Latvian climate conditions overheating is not a big issue in traditional buildings since it happens only a couple of weeks per year air conditioners must still be installed to maintain thermal comfort. The need for cooling in recently built office buildings with large window area can increase signi cantly. It is therefore of great interest if the ther- mal comfort conditions can be maintained by PCMs alone or with reduced maximum power of installed cooling systems. Our initial studies show tha…
Experimental testing of phase change materials in a warm-summer humid continental climate
2019
Abstract The construction industry (and buildings) is one of the largest energy consuming and CO2 emitting sectors in the world. To counter this, more lightweight structures are being used and energy saving applications are being developed. Phase change materials (PCM) are materials that can be considered to tackle these new challenges. It has been proven that PCMs can be passively used to improve the thermal mass of lightweight structures, which improves thermal comfort and reduces peak cooling and heating loads and therefore provides energy savings. To use these materials in an active way, they should be used together with ventilation, cooling or heating equipment, and collectors to accum…
5-(4-Fluoro-phen-yl)-4-(4-pyrid-yl)-1,3-oxazol-2-amine.
2010
In the crystal structure of the title compound, C14H10FN3O, the plane of the isoxazole ring makes dihedral angles of 35.72 (9) and 30.00 (9)°, respectively, with those of the 4-fluorophenyl and pyridine rings. The plane of the 4-fluorophenyl ring makes a dihedral angle of 45.85 (8)° with that of the pyridine ring. The crystal structure is stabilized by intermolecular N—H...N hydrogen bonding. The two types of hydrogen bonds result in two chains, extending along the a axis, which are related by centres of symmetry.
N-{4-[3-(4-Fluorophenyl)pyrido[2,3-b]pyrazin-2-yl]-2-pyridyl}isopropylamine
2009
In the crystal structure of the title compound, C21H18FN5, the pyridopyrazine ring system forms dihedral angles of 33.27 (7) and 48.69 (9)° with the 4-fluorophenyl and pyridine ring, respectively. The dihedral angle of the 4-fluorophenyl and pyridine rings is 57.45 (8)°. The crystal packing is characterized by an intermolecular N—H...N hydrogen bond.
Electromagnetic Hyperthermia — Foundations and Computer Modelling
2006
The usage of heating power as a healing system has been well-known for long time. A completely new motivation, however, came up when heat treating was recognized as a new and promising form of cancer therapy. It was found that cancer growth was stopped at temperature higher than about 42 C. It created new subject of research in the area of application of electromagnetic fields in medicine. In the paper the two main methods of heating have been described and two kinds of devices have been presented. Some advantages and drawbacks of the methods are discussed.
Intuitive eating: A novel eating style? Evidence from a Spanish sample
2020
Contains fulltext : 217000.pdf (Publisher’s version ) (Closed access) Intuitive eating is defined as an adaptive way of eating that maintains a strong connection with the internal physiological signs of hunger and satiety. It has four elements: unconditional permission to eat whenever and whatever food is desired, eating for physical rather than for emotional reasons, reliance on hunger and satiety cues to determine when and how much to eat, and body-food choice congruence. In this study, we assessed the differences and similarities between intuitive eating, as measured with the Intuitive Eating Scale-2, and eating styles (restrained, emotional, and external eating), as assessed with the Du…
Sleep-time physiological recovery is associated with eating habits in distressed working-age Finns with overweight: secondary analysis of a randomise…
2021
Background Association of physiological recovery with nutrition has scarcely been studied. We investigated whether physiological recovery during sleep relates to eating habits, i.e., eating behaviour and diet quality. Methods Cross-sectional baseline analysis of psychologically distressed adults with overweight (N = 252) participating in a lifestyle intervention study in three Finnish cities. Recovery measures were based on sleep-time heart rate variability (HRV) measured for 3 consecutive nights. Measures derived from HRV were 1) RMSSD (Root Mean Square of the Successive Differences) indicating the parasympathetic activation of the autonomic nervous system and 2) Stress Balance (SB) indica…
Tratamiento de la imagen corporal en los trastornos de la conducta alimentaria desde la terapia online
2019
La insatisfacción corporal es uno de los factores predisponentes de los trastornos de conducta alimentaria (TCA) y las distorsiones perceptivas del tamaño corporal es un criterio diagnóstico de estos. Actualmente, se han desarrollado intervenciones online para reducir los factores de riesgo de los TCA. El objetivo de este trabajo es llevar a cabo una revisión de la literatura científica sobre el tratamiento de la imagen corporal en los TCA desde la terapia online y poner de manifiesto los avances generados. Se realizó una búsqueda en las bases de datos PsycNET, Scopus y Web of Science. La búsqueda se centró en revisar los programas de intervención para TCA con TIC en el tratamiento de la im…
Inhibition of imidazolidinone intermediate formation in the aldol reactions catalyzed by zinc–prolinamide complexes
2011
Abstract The use of zinc salts as cocatalysts in aldol condensations catalyzed by single prolinamide (and in the extension by other more complex prolinamides) can prevent the formation of the parasitic intermediate imidazolidinone, with faster and also more stereoselective reactions than those catalyzed by the free amine. This new finding, together with this ion’s already known properties, make zinc salts highly suitable additives for aldol reactions catalyzed for prolinamide derivatives.
Chemoselective heterogeneous iridium catalyzed hydrogenation of cinnamalaniline
2020
International audience; Selective hydrogenation of unsaturated imines over heterogeneous catalysts is an ecologically feasible and effective way to produce commercially valuable saturated imines and unsaturated amines under mild conditions, avoiding the utilization of toxic halides. The liquid-phase hydrogenation of a model imine, cinnamalaniline, over Ir, Ru, Pd and Au catalysts was studied in polar protic (methanol, 2-propanol), polar aprotic (methyl tert-butyl ether) and non-polar aprotic (toluene) solvents at 40-80°C under atmospheric hydrogen pressure. Different metal oxides (Al 2 O 3 , ZrO 2 , SiO 2) and carbon composites based on carbon nitrides synthesized by pyrolysis of ethylenedi…
