Published: January 2022

Abstract
Pre-drying prior to freezing may reduce several freezing drawbacks. Nevertheless, drying may cause nutritional quality losses. Instant Controlled Pressure Drop process has been proposed to intensify pre-drying process. This research is dedicated to study the evolution of the main bioactive compounds (total phenolics, flavonoid, and tannins contents) of quince dehydrofrozen fruits. Fresh samples were subjected to air drying at 40 °C and 3 m s−1 air velocity down to a final water content of 0.3 g g−1 db. Pre-dried samples were Instant Controlled Pressure Drop (DIC) treated under different conditions, i.e. saturated steam pressure (P) and treatment time (t), following a 2-factor/5-level Experimental Design. Treated fruits were frozen at –30 °C then were thawed at 20 °C in order to study the impacts of DIC on phenolic compounds. Response Surface Methodology (RSM) confirmed that pressure was the most influencing parameter in terms of polyphenol, flavonoid, and tannins contents. Finally, DIC pre-treatment allowed the improvement of phenolic content retention compared to untreated DIC samples.

Background. The study of anemia causes in children born prematurely remains the urgent problem due to the continuous search for effective ways to prevent and treat it.Objective. The aim of the study is to study the anemia severity in premature infants, peripheral blood test results (MCV, MCH, MCHС), serum iron, and ferritin at different gestational periods.Materials and methods. 82 medical records of preterm infants were analyzed. 12 children were extremely premature (EР), 36 were very premature (VP), 27 were moderately premature (MP), and 7 were late premature (LP). The frequency of anemia, its severity, and laboratory indicators of iron metabolism were studied.Results. In EР infants, anemia developed in 100% (severe and moderate form in 16.7%, mild in 66.6%), in VP — in 94.6% (of which severe form in 5.6%, moderate — 22%, mild — 67%). Severe forms were not detected in children over 32 weeks of gestation. In infants with ЕР, the iron level at 2 weeks Me (median) 10.6 μmol/l [8.8–12.1], which is lower than in the comparison groups: VP — 15.9 [12.3–18.9] (p = 0.007), MP — 18,7 [15.8–20.5] (p = 0.0002), LP — 14,0 [16.2–23.8] (p = 0.011). Serum ferritin in the EР group is 58.4 μg/l [52.8–71.7], lower than the level in children with OH — 165.5 μg/l [77.3–195] (p = 0.03). The indicators MCV, MCH did not reflect the etiology of anemia, MCHC is reduced in all groups. With oral subsidization of 3-valent iron, its level increase in EР: before treatment — 10.65 μmol/l [8.2–12.1], after 2 weeks — 21.95 μmol/l [17.8–23,9] (p = 0.011).Conclusion. Severe and moderate degrees of early anemia of prematurity are diagnosed in the EР and VP groups. Significant deficiency of serum iron was detected in EР at the age of 2 weeks. MCHC less than 33.1% was registered in all gestational periods, it can be the marker of early anemia of prematurity. Iron supplement is required for EР.

W niniejszej pracy zbadano możliwości wykorzystania technik chromatografii gazowej GC-FID oraz GC-MS wspomaganych klasyczną chromatografią cieczową LC do badania składników biooleju pochodzącego z pirolizy biomasy stałej. Badania biomasy i produktów jej przerobu mają na celu rozwój technologii paliw proekologicznych i/lub zawierających frakcje otrzymywane z biomasy lub surowców odpadowych. Celem tych działań jest stopniowe zwiększanie wykorzystania źródeł energii pochodzących z surowców odnawialnych przy jednoczesnym ograniczaniu zastosowania surowców kopalnych. Jest to jedno z działań, których efektem ma być ograniczenie emisji GHG. Działanie to jest związane z wytycznymi dyrektyw Unii Europejskiej nakazujących wzrost udziału odnawialnych źródeł energii w transporcie oraz energetyce. Są to dyrektywy 2003/30/WE oraz 2009/28/WE, dotyczące promowania użycia biopaliw lub innych paliw odnawialnych w transporcie oraz wzrostu udziału pozyskiwania energii ze źródeł odnawialnych w różnych sektorach krajów Wspólnoty Europejskiej. Energetyczne wykorzystanie biomasy to jeden z głównych obszarów zainteresowania polityki energetycznej Polski, zbieżnej z celami polityki wyznaczonymi przez Unię Europejską. W niniejszym artykule dokonano przeglądu literatury w zakresie rodzajów biomasy występującej w Polsce oraz zastosowania technik chromatografii gazowej i cieczowej (Py-GC, GC-MS, GC-FID) w badaniu ciekłych produktów procesu pirolizy biomasy. Opracowano warunki chromatograficzne badania produktów ciekłych pirolizy biomasy stałej przy wykorzystaniu reaktora mikrofalowego do pirolizy jako elementu aparatury umożliwiającego badania technikami chromatograficznymi. Przy zastosowaniu dobranych warunków analitycznych wykonano badania ciekłych produktów pirolizy biomasy: miskantu olbrzymiego, słomy, trocin sosnowych, łusek słonecznika i ziaren kawy. Zidentyfikowano składniki biooleju pochodzącego z pirolizy biomasy i zaproponowano metodę oznaczania ilościowego składników biooleju. Wykazano możliwość jednoczesnego zastosowania różnych technik chromatografii gazowej w celu poznania składu chemicznego biooleju pochodzącego z pirolizy mikrofalowej różnego rodzaju biomasy stałej.

Abstract
There are abundant limestone resources in Weibei area. However, under the influence of a complex geological environment and harsh external environment, they often suffer from various types of serious geological disasters, which seriously threaten the safety of the people in the mining area and the development of mining resources. Therefore, it is urgent to carry out relevant governance. Firstly, combined with the field engineering geological data of a typical limestone quarry slope in Weibei, this paper makes a detailed geological survey of the study area. Then, the geometric model of the limestone mine slope is established to analyze the stress relationship between each block and its failure mode. Finally, a deep Newtonian force monitoring and early-warning system is set up in the dangerous area of large deformation of the slope to carry out the early warning treatment of reinforcement. The results show that (1) limestone is the main component of the mine, followed by mudstone, with developed joints and fissures, broken rock mass, and high hidden danger of engineering geological disasters; (2) in addition to bending and toppling failure on the surface of the mine slope, there are three failure modes: toppling failure along the joint surface, combined failure along the joint and plane, and failure along the outward structural plane; and (3) the NPR anchor cable is used to strengthen the slope, and the real-time monitoring of the slope force changes is realized, which has a particular reference significance for the study of similar significant deformation failure mechanisms of the slope and imminent slide warning.
‘You molded me like clay’: David Almond’s Sexualised Monsters
Authors: Sawers Naarah 
Published: January 2022

Monsters and the Gothic fiction that creates them are therefore technologies, narrative technologies that produce the perfect figure for negative identity. Monsters have to be everything the human is not and, in producing the negative of the human, these novels make way for the invention of human as white, male, middle-class, and heterosexual. (Halberstam, 1995, p.22).
Something unusual is happening in some of the most well-regarded, contemporary British children’s fiction. David Almond and Neil Gaiman are investing their stories with a seemingly contemporary feminist agenda, but one that is profoundly troubled by psychoanalytic discourses that disrupt the narratives’ overt excursions into a potentially positive gender re-acculturation of child audiences. Their books often show that girls can be strong and intelligent while boys can be sensitive, but the burgeoning sexual identities of the child protagonists appear to be incompatible with the new wave of gendered equity these stories ostensibly seek. In a recent collaborative essay with two of my colleagues teaching children’s literature at Deakin University, Australia, we considered the postfeminism of ‘other mothers’ and their fraught relationships with daughters in Neil Gaiman’s stories Coraline and The Mirror Mask (forthcoming). While Almond’s Skellig(1998) and Clay (2006) ostensibly tell very different fantastic tales, the differences, on closer inspection, seem only to relate to the gender of the protagonists. Gaiman’s girls and Almond’s boys undertake an identical Oedipal quest for heteronormative success, and in doing so reverse the politically correct bids for gender equality made on their narrative surfaces. When read through a psychoanalytical lens, the narratives also undo all the potential transformations of gendered politics made possible through the authors’ employment of magical realism that could offer manifold ways to disrupt binary oppositions. Indeed, that all four stories rely on the blurring of fantasy and reality might be more telling still about the ambivalence with which feminism is tolerated and/or advanced in a progressive nation like Britain. In such a culture the theoretical premise of equality is acceptable, but strange fantasies emerge in response, and gender difference is rearticulated.
Tiny Leaf Men and Other Tales From Outer Suburbia: Re-Presenting the Suburb in Australian Children’s Literature.
Authors: Oliver Kelly 
Published: January 2022

This paper explores how, through word and image, Tan’s Tales From Outer Suburbia challenges stereotypical representations of the suburban. Typically, suburban spaces have been represented as aesthetically bland, mundane, and ornamental. Tan takes these tropes and ironically re-deploys them anew, and in doing so undermines anti-suburban sentiment, which has dominated Australian literary and popular culture.
Although the notion of anti-suburbanism in Australian fiction has been well documented, its presence in children’s literature has received far less attention. As a case study, Tales From Outer Suburbia, signals the ability of children’s literature to present more positive representations of suburbia because of its inherent commitment to the socialisation of children, which is prioritised over the tradition of anti-suburbanism.
