Another possibility to increase renewable material content in PU foam and elastomer production is to apply lignin as co-polyol or/and filler. Lignin (from Latin lignum which means wood) isolated from the waste biomass is a natural polyol of a polyphenolic structure available in the form of a dark brown powder that is partially soluble in organic solvents. From chemical point of view, lignin is composed of car- bon, hydrogen and oxygen in different proportions; lignin contains hydroxyl, mehoxyl, car- bonyl and carboxyl functional groups in various amounts depending on its botanic origin. Hydroxyl groups and free positions in the aromatic ring determine reactivity of lignin and make it applicable in macromolecular chemistry [1]. The aim of this study was to varify applicability of lignin as a co-polyol in a solvent free production of castor oil based PU elastomers and tall oil amide based rigid PU foams. Tensile strength, toughness and surface hardness of PU elastomers and correlation between lignin content and closed cell content, density and compressive strengths for rigid PU foams were investigated Experimental In this work we studied the potential applicability of lignin (OH# = 120 mg KOH/g, A.V. = 74.2 mg KOH/g) (CIMV, France) as a co-polyol in a solvent free production of castor oil (OH# = 150 mg KOH/g, A.V. = 1.7 mg KOH/g) based PU elastomers and tall oil amide ((OH+NH)# = 286 mg KOH/g; A.V. = 4.4 mg KOH/g; H2O = 0.14 wt. %) based rigid PU foams. Prior to the synthesis we first prepared fine dispersion of powdery Kraft lignin in cas- tor oil and tall oil amide. Then we diluted the prepared up to 50 % dispersions in excessive amount of corresponding oil polyol and amide and in case of the foam preparation we added surfactants, catalysts and blowing agents. For foam production we made mixtures with differ- ent lignin content (0-50 wt. % in tall oil polyol) and reacted with polymeric 4,4'-

Understanding urban inequality and scaling law: A human mobility perspective Qi-Li Gao∗1, Yikang Wang†1 and Chen Zhong‡1 1Centre for Advanced Spatial Analysis, University College London GISRUK 2023 Summary Existing research mainly examined the urban scaling laws of social inequality based on income variable. Other forms of socio-spatial inequalities and their relationship with population size have not been well understood. Because of the powerful ability of human mobility in revealing socio-spatial inequality and the availability of data sources, this study extends the literature by introduced three types of mobility indicators (i.e., number of activity points, radius of gyration and self-containment). The results show that different characterisation of inequality present different spatial patterns and lead to different scaling laws. Overall, the inequalities in terms of the examined mobility dimensions don’t scale super-linearly with the population size, suggesting the complex nature of urban systems and the social phenomenon. KEYWORDS: urban inequality, scaling law, human mobility, gini. 1 Introduction Socio-spatial inequality, describing unequal access to urban resources and opportunities, has been an essential concern for urban policies. An increased inequality has been witnessed worldwide with social polarization and globalisation (Tammaru et al., 2020). Reducing inequality has become one of the key Sustainable Development Goals (SDG 10). It is believed that inequality is particularly high in large cities. For example, a positive relationship between city size and income inequality was observed (Baum-Snow and Pavan, 2013). The evidence mainly came from income based on census data and the Gini coefficient. Due to the limited fine-grain data, the other forms of socio-spatial inequalities and urban scaling theories have not been extensively studied. In this study, we aim to answer three key questions to fill the above-mentioned gaps. • How to measure urban inequality from the human mobility perspective. ∗qili.gao@ucl.ac.uk †yikang.wang.21@ucl.ac.uk ‡c.zhong@ucl.ac.uk

Finland Academic Research Science Publishers ISSN: 2945-4492 (online) | (SJIF) = 8.09 Impact factor Volume-12| Issue-12| 2024 Published: |22-12-2024| 630 Publishing centre of Finland ETHERIFICATION, OXIDATION, ALKYLATION AND SKELETAL TRANSFORMATIONS OF ECDYSTEROIDS https://doi.org/10.5281/zenodo.14527081 Soatboyeva Mukhayyo Master, Karakalpak State University, Nukus, Karakalpakstan Abstract Phytoecdysteroids (PEs) are naturally occurring polyhydroxylated compounds with a structure similar to that of insect molting hormone and the plant hormone brassinosteroids. PEs have a four-ringed skeleton composed of 27, 28, 29, or 30 carbon atoms (derived from plant sterols). The carbon skeleton of ecdysteroid is known as cyclopentanoperhydrophenanthrene and has a β-sidechain on C-17. ECs are polar steroids, and their solubility is identical to that of sugar molecules; thus, they are lipophilic and soluble in aqueous mediums. However, mammalian steroidal hormones are relatively non-polar and have variable structures. Keywords phytoecdysteroids, ecdysteroids, etherification, ecdysone, 20- hydroxyecdysteroid. 1. Introduction The name ecdysteroids (ECs) originates from the Ancient Greek word ecdysis, which means ―stripping‖, ‗‗the shedding of an exoskeleton in insects‖. Butenandt and Karlson [1] isolated the first EC—ecdysone—from silkworm pupae. Later, its structure was reported via X-ray crystallography [2]. ECs are steroidal hormones initially found in animals that control insect molting or ecdysis and other important metamorphotic processes in arthropods [3]. ECs have a polyhydroxylated four- ringed skeleton bearing 27–30 carbon atoms derived from cholesterol or other sterols. Depending on the natural source, ECs are subdivided into three groups: phytoecdysteroids (PEs), zooecdysteroids, and mycoecdysteroids. The naturally occurring ECs found in plants are differentiated from the ECs found in animals. However, 20-hydroxyecdysone (20-HE) is the most common and widely used [4,5,6,7]. Many ECs are present in plants and animals, such as 20-HE, ecdysone, ajugasterone C, polypodine B, and cyasterone (Figure 1).

A partir de una visión paradigmática en educación, se realiza una medición cuantitativa a poblaciones de diversos niveles educativos para verificar las condiciones de aprendizaje propuestas por dos teorías rivales ante un escenario de crisis de conocimiento diagnosticado por Enkvist en la transición de la escuela sueca, la cual estaba organizada por un modelo de aprendizaje riguroso hacia un modelo de educación de gobernanza igualitaria. Se advierte que el diagnóstico de la autora no toma en cuenta las nuevas necesidades del mercado de talentos dirigido por el Estado y propiciado por los acuerdos internacionales. Palabras clave: epistemología, paradigma, conocimiento, inteligencias, alfabetización Abstract. Starting from a paradigmatic vision in education, a quantitative mediation is carried out on populations of different educational levels to verify the learning conditions proposed by two rival theories in the face of a knowledge crisis scenario diagnosed by Enkvist in the transition from the Swedish school, the which was organized by a rigorous learning model towards an egalitarian governance model of education. It is noted that the author's diagnosis does not take into account the new needs of the state-directed talent market fostered by international agreements.

Searching for Quasi Periodic Pulsations in flares from low mass stars using TESS data Gavin Ramsay (Armagh, UK); Dmitrii Kolotkov (Warwick, UK); Gerry Doyle (Armagh); Lauren Doyle (Warwick) QPPs from Solar observations Solar Flare observed using Solar Dynamic Observatory NASA/SDO QPPs have been seen in Solar Flares at optical, X-ray and radio wavelengths and enables physical conditions in the flare region to be determined and the nature of flare to be better understood. QPPs from low mass stars Using TESS 2 min data from Cycles 1 & 2 we searched the light curves of 15437 low mass stars for high (>0.5 mag) amplitude flares. We identified candidate QPPs from 11 flares from 7 low mass stars. We show the stars position in the Gaia HRD below. Abstract: We have searched the light curves of low mass stars with TESS 2 min cadence data in Cycles 1 & 2 for Quasi Periodic Pulsations (QPPs). We identified 11 flares from 7 stars which have QPPs with periods ranging from ~10 min to 70 min. We use several methods for determining the loop length of the flares and find they can extend to a handful of stellar radius. Based on scaling relationships we determine the magnetic field strength in the coronal loops and compare the loop lengths to distance to the habitable zone for the host star.

Matusz Hübner, MA Institute for the History of Science Polish Academy of Sciences STANISŁAW MICHALSKI THE FOUNDING FATHER OF THE SCIENCE OF SCIENCE INTRODUCTION Stanisław Michalski (1865–1949), Polish educational and scientific activist, believed that theoretical reflection, which is considered as a part of – as he called it – “knowledge of science” (1923) or “science of science” (1929), should be undertaken simultaneously to the working practices for the development of science. He presented this program in the yearbook “Nauka Polska Jej Potrzeby, Organizacja i Rozwój” [“Polish Science: Its Requirements, Organization and Development”] (1918– 1947), founded and edited by him, which was a forum for the science of science.
