Functional connectivity underlying hedonic response to food in female adolescents with atypical AN: the role of somatosensory and salience networks.

Atypical anorexia nervosa (AN) usually occurs during adolescence. Patients are often in the normal-weight range at diagnosis; however, they often present with signs of medical complications and severe restraint over eating, body dissatisfaction, and low self-esteem. We investigated functional circuitry underlying the hedonic response in 28 female adolescent patients diagnosed with atypical AN and 33 healthy controls. Participants were shown images of food with high (HC) or low (LC) caloric content in alternating blocks during functional MRI. The HC > LC contrast was calculated. Based on the previous literature on full-threshold AN, we hypothesized that patients would exhibit increased connectivity in areas involved in sensory processing and bottom-up responses, coupled to increased connectivity from areas related to top-down inhibitory control, compared with controls. Patients showed increased connectivity in pathways related to multimodal somatosensory processing and memory retrieval. The connectivity was on the other hand decreased in patients in salience and attentional networks, and in a wide cerebello-occipital network. Our study was the first investigation of food-related neural response in atypical AN. Our findings support higher somatosensory processing in patients in response to HC food images compared with controls, however HC food was less efficient than LC food in engaging patients' bottom-up salient responses, and was not associated with connectivity increases in inhibitory control regions. These findings suggest that the psychopathological mechanisms underlying food restriction in atypical AN differ from full-threshold AN. Elucidating the mechanisms underlying the development and maintenance of eating behavior in atypical AN might help designing specific treatment strategies

Waste immobilization and environmental sustainability in glass-ceramics glazes development

The current work investigated the formulation of glazes using recycled CRT (Cathode Ray Tube) waste glass powder mixed with basalt, kaolin and other additives. New glaze compositions can be crystallized in order to improve the mechanical and chemical properties of fast-fired glazed tiles. These glazes are characterized by high resistance to abrasion

Influence of temperature and humidity on the spectrophotometric properties of the coated glasses

W artykule omówiono charakterystykę i rolę powłok stosowanych w oszkleniach budowlanych. Przedstawiono warunki starzeniowe, którym poddano szkło z powłoką przeciwsłoneczną. Wyznaczono parametry świetlne i energetyczne szkła powłokowego nie poddanego działaniu wysokiej i niskiej temperatury i wilgotności, oraz po procesie starzenia. Porównano otrzymane charakterystyki spektrofotometryczne szkła powłokowego przed i po działaniu czynników symulujących przyspieszone starzenie. Określono pierwiastkowy skład chemiczny powierzchni szkła powłokowego przed i po starzeniu metodą mikroskopii skaningowej. Dokonano analizy otrzymanych wyników, oraz oceny stopnia degradacji powłoki po działaniu wysokiej i niskiej temperatury i wilgotności.The article discusses the characteristics and role of the coatings used in construction glazing. The conditions aging which were subjected to antireflection coating glass were presented. The light and energy parameters of coating glass that were not exposed to high and low temperature and humidity and coating after aging were determined. The obtained spectrophotometric characteristics of coating glass before and after aging were compared. Elemental composition of the coating surface of the glass before and after aging by scanning microscopy method was determined. The analysis of the results and assess the degree of degradation of coatings after exposure to high and low temperature and humidity was performed

Coloured glasses for small producers of art glass

Technologia produkcji szkieł kolorowych barwionych w masie znana jest od dawna. Szkła te różnią się na tyle składem chemicznym, że nie możemy ich łączyć w dowolny sposób bez zwrócenia uwagi na ich parametry fizykochemiczne. Producenci szkieł kolorowych wykorzystywanych komercyjnie nie udostępniają składów produkowanych szkieł z uwagi na konkurencję, dlatego przeprowadzono próbę opracowania alternatywnych i tanich szkieł kolorowych umożliwiających dowolne połączenia kolorystyczne, wykorzystując surowiec zastępczy, jakim jest stłuczka szklana z recyklingu.The production technology of coloured glasses is known for a long time. The aforementioned glasses differ in chemical composition to such a degree, that we cannot combine them in any way, without having in mind their physical and chemical parameters. Manufacturers of coloured glasses, which are widely used commercially, do not provide compositions of the produced glasses. The project was to create an alternative and cheap coloured glasses, which allow any colour combinations, using waste material, in particular glass cullet from recycling
