This chapter challenges traditional views on Iron Age dress. Recent research has greatly enhanced our understanding of how textiles were manufactured in Iron Age Europe. The variety of qualities, textures, techniques, raw materials, colours, and cuts give insights into the detailed knowledge of the craftspeople involved. Textiles used for dress, blankets, or furniture fittings were appreciated not only for their appearance, but also for the quality of the work. In everyday life, their optical qualities were used to express and signal gender, social roles and status, while the labour expended on textiles found in wealthy burials underlines both the status of the deceased and the extent of conspicuous consumption in funerary rituals—for instance, for wrapping grave furniture and goods. The chapter also looks at experimental data showing how labour-intensive textile production was, and the types of clothing and accessories found in different archaeological contexts or depicted in visual representations.

Dogs have the tendency to bark at loud noises that they perceive as an intruder or a threat, and the hostile barking can often last up to hours depending on the duration of such noise. These barking sessions are unnecessary and negatively impact the quality of life of the others in your community, causing annoyance to your neighbors [1]. Having the rights to file noise complaints to the Home Owners Association, potentially resulting in fines or even the removal of the pet [2]. In this paper, we will discuss the development of an algorithm that takes in audio inputs through a microphone, then processes the audio and identifies that the audio clip is dog barks through machine learning, and ultimately sends the notification to the user. By implementing our application to the everyday life of dog owners, it allows them to accurately determine the status of their dog in real-time with minimal false reports.

Both the availability and the quality of covariance data improved over the last years and many recent cross-section evaluations, such as JENDL-4.0, ENDF/B-VII.1, JEFF-3.3, etc. include new covariance data compilations. However, several gaps and inconsistencies still persist. Although most modern nuclear data evaluations are based on similar (or even same) sets of experimental data, and the agreement in the results obtained using different cross-sections is reasonably good, larger discrepancies were observed among the corresponding covariance data. This suggests that the differences in the covariance matrix evaluations reflect more the differences in the (mathematical) approaches used and possibly in the interpretations of the experimental data, rather than the different nuclear experimental data used. Furthermore, “tuning” and adjustments are often used in the process of nuclear data evaluations. In principle, if adjustments or “tunings” are used in the evaluation of cross-section then the covariance matrices should reflect the cross-correlations introduced in this process. However, the presently available cross-section covariance matrices include practically no cross-material correlation terms, although some evidence indicate that tuning is present. Experience in using covariance matrices of different origin (such as JEFF, JENDL, ENDF, TENDL, SCALE, etc.) in sensitivity and uncertainty analysis of vast list of cases ranging from fission to fusion and from criticality, kinetics and shielding to adjustment applications are presented. The status of the available covariance and future needs in the areas including secondary angular and energy distributions is addressed.

For more than half a century, the use of plastic in agriculture has given farmers opportunities for growing fruits and vegetables regardless of the season, and at the same time achieving better quality compared to open-field cultivation. The use of plastics, through various specific techniques, helps reduce the consumption of various resources such as water, energy, fertilizers or pesticides.We could say that without these plastics a significant amount of cultivated fruits and vegetables could not be harvested in early conditions and could not be preserved and conditioned in controlled parameters.Plastic is a very important material for economy but also in everyday life. The use of plastic in agriculture has increased from year to year, thus contributing to both the increase of agricultural production and the improvement of the quality of food.Plastics are a wide range of synthetic or semi-synthetic materials that are used for various purposes. In the plastic industry, are used raw materials, such as cellulose, coal, natural gas, salt and, of course, crude oil. Plastics are extremely versatile materials and are ideal for a wide range of applications for industry as well as for consumers.

Abstract This paper conceptualizes affective urbanism as both research framework and praxis, engaging professionals and concerned publics alike in the insurgent making of cities. With its focus on affect and bodily encounters, it taps into the rich knowledge of practices of improvising and inventing in everyday life, which tend to fall outside the realm of discursive and visual representations. An analysis of spatial practices of the collective Plataforma de Afectados Por La Hipoteca in Barcelona illustrates how a mobilization of affects fosters not only individual, but first and foremost a collective capacity to negotiate belonging, appropriate space and contest alienated conditions of everyday life. The argument rests on the hypothesis that affect implicates the ethical engagement with people at places of everyday life, thus producing a medium and means for transgressing socio-spatial divides and challenging practices of exclusion, othering and dispossession. The value of this kind of work does not necessarily lie in the quality of conceived or materialized design, but rather in enacting an inclusive and empathic design praxis which connects to people’s multiple lived spaces and cultivates lived space of deep and caring social relations.

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

The article presents two letters from V.A. Musin-Pushkin which he wrote to his bride shortly before the wedding in 1828 (the letters are kept in the Russian State Archive of Ancient Acts). The text of the letters reflects the context of the time and everyday life, the system of views and the peculiarities of the worldview of a young aristocrat, the specific features of intra-family interaction in the field of feelings, marriage, human relations which inevitably turn out to be associated with the concepts of the family honor, family duty, the need to preserve the status of a noble family. The author traces how the power hierarchy is manifested at the level of relations within a close circle of relatives, as well as how traditional patterns are combined with new elements. Vladimir Alekseevich Musin-Pushkin, the youngest son of the archaeographer Count A.I. Musin-Pushkin, was arrested in connection with the case of the Decembrists, transferred from the Guards to the army and exiled to serve in Finland, where he met his future wife, Emilia Karlovna Shernval von Wallen. The article provides details of the family life of this married couple, as well as private facts from the biography of some other members of the Musin-Pushkin family.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.
