Authors: Pylypenko Ihor , Kovalchuk Iryna , Tsyba Mykola 
Published: December 2023

The object of research is granular composites based on zirconium-iron alginates and laponite. The task of research is to determine the influence of the Zr:Fe ratio on the structure of granular composites and efficiency of uranium (VI) removal from aqueous solutions. The influence of the zirconium and iron ratio on the parameters of the material's pore structure has been established, particularly on the change in the content of micropores within the matrix. The specific surface area of the materials ranges from 86 to 112 m²/g. The sorption properties of the composites regarding uranium (VI) have been investigated. The impact of the charge of surface groups and the form of uranium (VI) presence in sulfate solutions on their sorption characteristics has been demonstrated. The maximum adsorption capacity reaches 265.1 µmol/g at pH 6. It is shown that an elevated electrolyte content positively affects the efficiency of uranium (VI) removal in neutral and alkaline medium. It has been established that structural changes in the materials occur due to the intensive interaction of iron ions and alginate molecules, resulting in the formation of a dense gel-like structure. The mechanism of uranium (VI) removal is associated with the formation of surface complexes in the presence of electrolytes. The synthesized granulated composites exhibit improved removal efficiency of uranium (VI) under conditions of high mineralization of solutions, making them attractive for potential use as sorbents. The obtained results can be utilized in the development of effective methods for purifying water environments from uranium (VI) in high mineralization conditions, which is a relevant issue in the field of nuclear energy and the removal of radioactive substances from water systems

The object of research is the production of C9 hydrocarbon resins by oligomerization of oil refining by-products.
In the technology of hydrocarbon resins by free radical oligomerization, there is a disadvantage in the use of high temperatures and a long reaction time. The resulting products have a dark color, which limits their use in paints and varnishes.
The technology of hydrocarbon resins, which consists in the suspension oligomerization of hydrocarbons of the C9 fraction in an aqueous medium, at low temperatures and stirring, was studied.
N-substituted amino peroxides, which are characterized by a low temperature of use, were used as initiators. The raw materials used were C9 fractions of liquid gasoline pyrolysis products with an unsaturated compound content of 54.7 %.
The optimal conditions were established: temperature – 364 K, time – 180 min, Re=10120, initiator concentration – 0.064 mol/l, the share of C9 fraction in the reaction mixture – 25 %. Under these conditions, a light hydrocarbon resin with a color index of 20 mg I2/100 ml and a softening point of 352 K was obtained.
The use of amino peroxide initiators allows for the suspension oligomerization of the hydrocarbon fraction C9 at low temperatures (303–353 K) and within a short reaction time (180 min). This oligomerization technology makes it easy to remove excess heat and maintain isothermal conditions in the reaction zone. This prevents the development of side oxidation reactions that cause darkening of the product.
The research results make it possible to improve the process of oligomerization of the hydrocarbon fraction using new initiators and obtain light-colored hydrocarbon resins. This will reduce energy costs for production and improve the characteristics of hydrocarbon resins

Published: December 2023

Aim: to study the histological structure and histomorphometric parameters of the thyroid gland in rats in the period after the completion of the 60-day administration of tartrazine and the creation of a through defect in the tibiae.Material and methods. One hundred and fifty white male rats were divided into five groups: groups T1 and T2 - 60 days of exposure to tartrazine at a dosage of 750 and 1500 mg/kg; group K+D – 60-day administration of saline solution and infliction of a defect in the tibiae; groups T1+D and T2+D – 60-day exposure to tartrazine at a dosage of 750 and 1500 mg/kg and causing a defect in the tibia. The histological structure and histomorphometric parameters of the thyroid gland were studied on days 3, 10, 15, 24 and 45.Results. In the T1+D and T2+D groups, mainly small follicles, lined with cuboidal shaped cells, and in some of them - a flat or columnar shaped cells were detected in the center of the gland from days 3 to 15. Many thyrocytes had a vacuolated cytoplasm and an intensely stained nucleus. The heterogeneous colloid partially filled or was practically absent in the follicles cavity, anemia of the capillaries between them was determined. Singly areas of the organ parenchyma with a significant accumulation of lymphocytes were detected. Histomorphometric study showed a decrease in the internal diameter of the follicles, lumen-epithelial index and nucleo-cytoplasmic ratio and the raise in the height of the follicular epithelium and the area of the cytoplasm of follicular cells.Conclusion. Sixty-day administration of tartrazine to rats and artificial traumatic bone injury leads, in comparison with the data of control groups, to a more pronounced change in the histological picture and morphometric data of the thyroid gland. The intensity and duration of changes are dosedependent: in the T1+D group, most of the qualitative and quantitative changes are smoothed out by 45 days, and in the T2+D group, many of them remain, and the body does not adapt to them.

Как автомобили подорвали мобильность
Authors: Маркс Пэрис 
Published: December 2023

Будущее, ориентированное на пригородные автомобили, открывало рыночные возможности для автомобильных компаний, застройщиков и производителей потребительских товаров. Их совокупного влияния в сочетании с блестящей маркетинговой кампанией оказалось достаточно, чтобы заставить политических лидеров откликнуться на их требования и направить значительные ресурсы на реализацию их видения будущего.
Перестроив способы общения, развлечения, покупки товаров и многое другое, компании, процветающие благодаря распространению интернета во всех уголках земного шара, теперь обращают свой взор на физическую среду, уделяя особое внимание транспортной системе. Однако после столетия жизни в городах, построенных для автомобилей, мы должны с осторожностью относиться к принятию масштабных генеральных планов, в которых не учитываются все последствия того, как элитные предложения могут отразиться на остальных людях.
В следующей главе автор доказывает, что нам нужна более совершенная транспортная система и, как следствие, более совершенные города. Автор обращается к истории автомобилестроения, чтобы проиллюстрировать, как транспортные системы — как в городах, так и за их пределами перестраивались на протяжении ХХ века, чтобы освободить место для автомобиля, и как эти изменения не были востребованы обществом, а скорее осуществлялись вопреки его желанию капиталистическими интересами.
Аргументация автора не сводится к тому, что современным городам не нужна существенная перестройка транспортной системы, равно как и не нужно переосмысливать подходы к городскому планированию. В последние годы все чаще обсуждается необходимость отказа от ориентированного на автомобили развития в пользу приоритета пешеходов, велосипедистов и общественного транспорта для создания более плотных, экологичных и прогулочных сообществ. Однако прогресс идет слишком медленно, учитывая вред и несправедливость существующей системы. Там, где изменения все же происходят, нередко они приносят пользу только богатым, исключая бедных и рабочий класс.
The origin, age, and conservation, of an ‘elevated platform’, Yarwondutta Rock, north-western Eyre Peninsula, South Australia
Authors: Twidale Charles Rowland 
Published: December 2023

Yarwondutta Rock is a dimpled platform that was shaped at ground level by soil moisture but subsequently elevated, not because of local tectonism, but by the erosional lowering of the surrounding pedimented plains. Concave or flared slopes fashioned in the erstwhile piedmont were revealed during this erosional phase which took place in the earlier Pleistocene. The elevated platform is now buttressed against dissection by the calcreted surrounding pediments.
It is concluded that in technical terms, Yarwondutta Rock appropriately can be referred to as an ‘elevated platform’.

Published: December 2023

Relevance. Long periods of development of steeply dipping deposits necessitate multiple adjustments of mining and technical system throughout an open pit life cycle. The decisions made determine the development strategy of a mining enterprise for a long period. The complexity of making such strategic decisions depends on numerous influencing parameters. These parameters have a different impact, have a variety of units of measurement, target values, and are not only quantitative but also qualitative. There is a need for new approaches to the choice of development strategy of the mining and technical system of an open pit, as well as its main subsystem – the opening-up of an opencast system. It is proposed to base these approaches on multi-criteria decision-making methods that consider many influencing parameters. Aim. Development of a methodology for choosing a strategy for sustainable development of the deep open pit mining and technical system based on multi-criteria decision-making methods and assessment of the opening system parameters. Objects. Mining enterprise, mining and technical systems, opening system. Methods. Literature review, system analysis, multi-criteria decision making. Results. The authors have determined the main strategies for development of the mining and technical system for deep open pits. These strategies aim at achieving the sustainable development of the mining and technical system: adjustment of the current stage mining parameters; transition to a new stage of mining; transition to a combined open-underground mining; mine closure. The key role of the opening system in the structure of the mining and technical system is substantiated to ensure its sustainable development. The authors systematized the main parameters for evaluating the pit opening system and set target values for each parameter. A review of the main multi-criteria decision-making methods used to solve various problems in the mining industry is made. A rank coefficient is proposed for choosing the mining and technical system development strategy. The calculation of this coefficient is based on a combination of the fuzzy AHP and CRADIS multi-criteria methods. A method was developed for selecting a strategy for sustainable development of the mining and technical system of deep open pits. A case study was conducted on the conditions of the Maly Kuibas open pit. The obtained results strongly suggest that the best strategy with the highest ranking is the transition to the combined development method.
