Blood self-sampling devices: innovation, interpretation and implementation in total lab automation
Authors: Poland Dennis C.W. , Cobbaert Christa M. 
Published: June 2024

Abstract
The introduction of the vacuum tube in 1949 revolutionized blood collection, significantly improving sample quality and patient comfort. Over the past 75 years, laboratory diagnostics have evolved drastically, from manual to automated processes, reducing required test volumes by over 1,000 times. Despite these advancements, venous blood collection presents logistical challenges, including centralized scheduling and a large volume of biological waste due to the imbalance between the needed blood volume (often very little) and the collected volume (often in excess). The COVID-19 pandemic further emphasized the need for decentralized healthcare solutions and patient empowerment. Capillary blood collection, widely used in point-of-care testing, offers a promising alternative, particularly for patients facing frequently, or difficulties with, venous sampling. The Leiden University Medical Center in the Netherlands experienced a 15 % reduction in volume of laboratory tests during and after the pandemic, attributed to patient preference for local blood collection and testing. To address these challenges, self-sampling devices are emerging, empowering patients and streamlining sample logistics. However, challenges such as cost, transportation regulations, and sample volume adequacy persists. Robust devices tailored for total lab automation and sustainable practices are crucial for widespread adoption. Despite hurdles, the integration of self-sampling into diagnostic processes is inevitable, heralding a shift towards patient-centered, proactive healthcare. Practical recommendations include robust device design, ease of use, affordability, sustainability, sufficient quality and acceptability by seamless integration into laboratory workflows. Although obstacles remain, self-sampling represents the future of laboratory diagnostics, offering convenience, cost-effectiveness, interoperability and patient empowerment.
Fast analysis approach for instability problems of thin shells utilizing ANNs and a Bayesian regularization back-propagation algorithm
Authors: Nguyen T. N. , Zhang Dongsheng , Singhatanadgid Pairod 
Published: June 2024

AbstractThis research develops a data-driven methodology for structural instability problems with highly nonlinear, difficult, noisy, and small data. A fast analysis and prediction (FAP) approach for instability problems of thin shells is first proposed. This approach contains two phases: the fast numerical analysis and the pure prediction utilizing artificial neural networks (ANNs) incorporated with the Bayesian regularization (B-R) algorithm as follows: (1) in Phase 1 (the fast numerical analysis), post-buckling analysis is conducted utilizing a minor amount of load steps. The load–displacement relation achieved from Phase 1 is not exact because of the small number of load steps utilized; (2) in Phase 2 (the prediction), the loads and deflections achieved from Phase 1 were employed as the data for training ANNs. The trained networks, including the load and displacement networks, were employed to fast predict loads and deflections at any step of the post-buckling analysis. After utilizing Phase 2, a smooth, complete and exact load–displacement curve was achieved. In Phase 1, the available formulation for post-buckling analysis of thin shells in the literature was utilized. Five popular types of instabilities chosen to confirm the effectiveness and exactness of the FAP were snap-through, snap-back, softening–hardening, kink instabilities, and delamination buckling and post-buckling of composites. The high exactness and effectiveness of the FAP were confirmed in the numerical verification section. The present approach saves a huge computation compared to the other ones. It was found that ANNs incorporated with the B-R algorithm have notable advantages compared to numerous neural networks. The proposed approach is applicable to simulations or experiments where data are “expensive”, highly nonlinear, difficult, and limited. Utilizing the proposed approach for these fields can dramatically save time and money.

Abstract
Traditional food packaging coated paper is not environmentally friendly, and there have been many studies on oil- and water-resistant paper for food packaging. However, preparing oil- and water-resistant paper that is plastic-free, fluorine-free, and environmentally friendly is still a significant challenge. In this study, oil- and water-resistant paper for food packaging are prepared by layer-by-layer assembly and mixing coating methods. The layer-by-layer assembly coated paper exhibits excellent water resistance (Cobb 60 value of 20.5 g/m2, water contact angle value of 132°). The mixed coated paper not only has good water resistance (Cobb 60 value of 27.1 g/m2, water contact angle value of 131°), but also has excellent oil resistance (kit rating value of 8/12). The oil-resistant and waterproof mechanism of the coated paper is confirmed through scanning electron microscopy. In addition, the mechanical performance and coating adhesion of the mixed coated paper are the best, with an increase in the tensile index of 73.1 %. This study provides a feasible strategy for preparing biodegradable, plastic-free, and fluorine-free food packaging oil- and water-resistant paper, which is beneficial for reducing plastic pollution.

Published: June 2024

Abstract
The aim of this study is to energy harvesting and modeling from a soft and flexible nanogenerator based on nanofibers (PVDF/ZnO-RGO) on the arm of a multi-rotor UAV. The nanogenerator modeling was done to improve the usability of piezoelectric nanogenerators to provide part of the electric energy required by drones. Tests were conducted on the experimental setup and practical flight conditions. In each test and a period of 30 s, the vibration signals of the UAV arm were stored, and the vibration data extracted in the time domain and the electrical voltage of the nanogenerator were obtained through the vibrations of the drone, and its values were recorded in each experiment. After signal processing, the best vibration features were used for modeling. In the modeling process, some data were considered for training and testing in ANFIS network. The ANFIS inputs included the selected vibration features and the outputs included the stored voltage. The modeling results were analyzed based on increasing the amplitude of vibrations and the duration of exposure of the nanogenerator to vibration led to higher voltage generation. The maximum voltage recorded during the 30-s flight time of the tested UAV was 64 mV at 3.54, 49.8, and 0.48 Hz along the x, y, and z axes, respectively. The results showed that the application of energy harvesting on different vibration systems could be improved through modeling. It can be used to predict the amount of electric energy produced according to the vibrations of the drone in the future.

Published: June 2024

Abstract
In this study, three starch hydrogels composite prepared using different ratios of starch, citric acid, acrylamide, and MgO nanoparticles (referred to as St1-g-(CA-AM), St2-g-(CA-AM), and St3-g-(CA-AM) MgO). These materials were assessed using FT-IR, SEM, and EDX. The adsorption of 134Cs(I) and 60Co (II) onto these materials studied using radiometric analysis. The investigation focused on how temperature, contact duration, initial metal ion concentration, and pH of the solution affected the sorption efficiency. It is found that a pH value of 7 optimized the adsorption reaction, reaching equilibrium after 40 minutes. The kinetics of the adsorption followed a pseudo-second order model. The Langmuir model adequately explained the sorption mechanism, supported by the analysis of isotherm models. The monolayer adsorption capacities for 60Co (II) and 134Cs (I) were 113.38 and 100.2 mg g−1, respectively. The thermodynamic study indicated that the sorption process is both endothermic and spontaneous.

На основании изучения фауны и микрофоссилий возраст тургинской свиты в обнажении Миддендорфа определен как конец баррема-начало апта. Состав комплексов фауны и палиноморф позволяет коррелировать тургинскую свиту с формацией Yixian и низами формации Jiufotang Северо-Восточного Китая. Результаты петрографического и геохимического анализов, а также изучения микрофоссилий показали, что отложения накапливались в мелководном озере со спокойной гидродинамикой, иногда в условиях дефицита кислорода. По составу спорово-пыльцевых комплексов восстановлены климатические условия (умеренно теплый климат, переходный к субтропическому) и тип растительности (хвойные леса с примесью лиственных пород).
The age of the Turga Formation in the Middendorf’s outcrop is determined as latest Barremian-earliest Aptian based on fauna and microfossil assemblages. The composition of the fauna and palynomorph assemblages allows correlations between the Turga Formation and the Yixian Formation and lower part of the Jiufotang Formation of Northeast China. Results of the petrographic and geochemical analysis as well as microfossil studies showed that sediments accumulated in a shallow lake with low-energy hydrodynamics, sometimes under low-oxygen conditions. Climate features (warm temperate climate transitional to subtropical) and type of vegetation (coniferous forests with admixture of hardwoods) are reconstructed taking into consideration the composition of spore-pollen assemblages.

Published: June 2024

Путь к ярусному расчленению венда должен лежать через составление полного сводного геологического разреза этого отрезка земной коры - последовательности геологических тел, каждое из которых отражает определенное состояние экосистем. В качестве основы ярусной шкалы венда предлагается использовать сводный разрез венда Сибирской платформы, представляющий собой последовательность геологических тел регионального и субглобального масштаба, каждое из них отражает определенное состояние либо однонаправленное изменение геосистемы, обусловленные периодическим проникновением на шельф обстановок, относительно насыщенных кислородом, в перерывах между широкомасштабными океанскими событиями аноксии и эвксинизации. Вариации окислительно-восстановительных условий должны были сопровождаться переменной доступностью питательных веществ, что не могло не сказаться на общем характере макроэволюционных и макроэкологических процессов. Геологическая летопись венда Сибирской платформы также свидетельствует о периодическом ощелачивании Мирового океана. В сводном разрезе венда Сибирской платформы различаются, по крайней мере, пять таких событий, с которыми связывается ощелачивание. Предлагается гипотеза, согласно которой событийное ощелачивание могло стать причиной наблюдаемой периодичности в появлении и исчезновении специфических осадочных текстур в карбонатных отложениях, дискретного характера раннедиагенетической цементации алюмосиликокластических осадков и фоссилизации остатков мягкотелых организмов в венде.
The way towards the stage subdivision of the Vendian starts with the assemblage of a complete composite geological section of this interval of the Earth’s history, a succession of geological bodies each reflecting a certain ecosystem state. A Vendian composite section of the Siberian Platform, which is a succession of regional to sub-global scale geological bodies reflecting particular states or unidirectional transformations determined by episodic expansion of relatively oxygen-rich environments onto the shelf and alternating with large-scale oceanic anoxia and euxinia events is proposed as a reference for constructing the stage subdivision of the Vendian. The redox instability had to be accompanied by changes in nutrient availability and could not but affect the course of macroevolution and macroecology. The geological record of the Vendian of the Siberian Platform is also marked by episodic increase in alkalinity of the World Ocean. At least five such alkalinity events could be provisionally identified in the composite section of the Vendian of the Siberian Platform. A hypothesis is proposed suggesting that the alkalinity events could control the appearance and disappearance in the geological record of a distinctive suite of sedimentary structures in carbonates, the discrete nature of early diagenetic cementation of aluminosilicoclastic sediments, and fossilization of soft-bodied organisms in the Vendian.

Laut Timor adalah salah satu perairan strategis yang penting untuk kegiatan pelayaran kapal selam. Informasi akurat tentang nilai densitas di perairan Laut Timor masih sangat terbatas dan sulit dilakukan secara tepat. Penelitian ini menggunakan 6 stasiun observasi yang dianggap mewakili daerah penelitian untuk melihat karakteristik sekitar daerah penelitian. Penelitian ini bertujuan untuk mengestimasi nilai densitas air laut di Laut Timor dengan regresi linear menggunakan data model Copernicus Marine Environment Monitoring Service (CMEMS) sebagai variable independent dan data in situ World Ocean Database (WOD) sebagai variable dependent di lapisan permukaan, lapisan thermocline dan lapisan dalam. Komputasi yang digunakan untuk menentukan nilai densitas menggunakan persamaan TEOS-10 UNESCO yang telah diinstall di Ocean Data View (ODV) dan hasilnya digunakan untuk pembangunan persamaan regresi menggunakan modul Analysis Toolpak yang telah diinstall di Microsoft excel. Data yang digunakan meliputi posisi, kedalaman, salinitas, suhu pada kedalaman tertentu, kemudian dilakukan forecasting model secara statistika untuk memprediksi densitas air laut di Laut Timor selama 12 hari di lapisan permukaan, lapisan Termoklin dan lapisan dalam. Penelitian ini penting karena nilai densitas laut yang akurat sangat diperlukan dalam mendukung pelayaran kapal selam, terutama dalam hal navigasi dan keseimbangan hidrostatik. Hasil penelitian ini berupa nilai forecasting estimasi nilai densitas pada 3 lapisan kedalaman pada lapisan permukaan nilai tertinggi 1.021,8 kg/m³ dengan nilai rata-rata MAPE 0,25% dan lapisan Termoklin densitas tertinggi 1.024,79 kg/m³ dengan nilai rata-rata MAPE 1,65% dan laut dalam densitas tertinggi 1.032,30 kg/m³ dengan nilai rata-rata MAPE 0,021%. Diharapkan bahwa penelitian ini dapat memberikan kontribusi positif dalam pengembangan ilmu pengetahuan -oseanografi di Laut Timor.

Понятие и структура уголовно-организационных отношений
Authors: Bushtets Nikita 
Published: June 2024

В настоящей статье автор предпринимает попытку на основе теоретических разработок общей теории права об организационных нормах и дискуссии отечественных правоведов об уголовно-процессуальных отношениях выделить в системе уголовного процесса особый вид норм и отношений, именуемых уголовно-организационными . Задача таких норм заключается в создании организационных условий для эффективного функционирования уголовно-процессуальных институтов . В связи с этим автор подвергает рассмотрению предпосылки, способствующие выделению уголовно-организаци-онных отношений в системе уголовного процесса . Далее автор рассматривает функциональное предназначение уголовно-организационных норм и отношений в системе действующего законодательства, исследует их внутреннюю структуру и предлагает к применению соответствующий понятийный аппарат для выделенных элементов отношений . В частности, выделяются такие понятия, как «организация уголовного про-цесса», «уголовно-организационные нормы уголовно-процессуального права», «объект уголовно-организационных отношений», «субъекты уголовно-организационных отношений», «уголовно-организационные отношения в уголовном судопроизводстве» как в широком, так и узком смысле . Далее автор формулирует круг вопросов, относящихся к сфере уголовно-организационных отношений, а также выделяет основные направления их теоретического и практического развития . В заключение автор фор-мулирует ряд предложений по совершенствованию российского уголовного процесса с учетом роли уголовно-организационных отношений . Делаются выводы о том, что уголовно-организационные отношения выступают надстройкой к базовому институту и уголовному судопроизводству в целом, позволяя наладить его должную работу в соответствии с замыслом законодателя . В связи с этим автор предлагает выделить уголовно-организационные отношения как разновидность правовых отношений, обладающих рядом особенностей, которые требуют отражения при изложении законов и других нормативных правовых актов, т .е . внедрить новые правила законодательной техники . Исходя из этого предлагается обособить уголовно-организационные нормы в самостоятельный раздел законодательного акта (УПК РФ), что, по мнению автора, значительно упростит правоприменительную практику и будет способствовать качественному улучшению работы уголовно-процессуальных институтов и уголовного судопроизводства как такового .Для цитирования: Буштец Н.В.
