Effects of partial lignin extraction on rheological characteristics and combustion performance of high solids bamboo kraft black liquor
Authors: Guo Kangkang , Xu Yongjian , Chen Xin , Yin Xuefeng 
Published: September 2024

Abstract
This study investigates the impact of lignin extraction on the rheological and combustion properties of high-solids bamboo kraft black liquor (BKBL), focusing on viscosity reduction and silicon interference mitigation. Lignin was extracted from BKBL using CO2 acid precipitation. The effects on viscosity, silicon content, calorific value, and Volumetric Isothermal Expansivity (VIE) were systematically analyzed. Extracting 25 % of lignin reduced the apparent viscosity of BKBL and achieved a 33 % desilication rate. However, this extraction also led to a proportional decrease in calorific value and VIE, with a 15 % extraction resulting in approximately 11 % and 13 % reductions, respectively. An extraction rate of 15–25 % is recommended to balance viscosity reduction and silicon removal with minimal impact on boiler combustion efficiency. This study provides practical insights into optimizing lignin extraction from BKBL, offering significant operational, economic, and environmental benefits for the bamboo kraft pulping industry.

Abstract

Introduction
Microplastics (MPs) have emerged as one of the global principal marine environmental problems in many countries, including Indonesia. However, fewer studies have been conducted on the MP impact on aquatic organisms. Thus, the present case study aimed to investigate the presence of MPs in mangrove sediments and coral reef fish in Biawak Island, West Java, Indonesia.

Materials and methods
The present study used a case study in which samples were collected at specific locations and time. Fish (15 individuals of three family taxa) and sediments were collected from three sampling stations (A, B, and C) at Biawak Island, West Java Province, Indonesia, in February 2023. The types and numbers of MPs were investigated under a monocular microscope.

Results
MPs were found in all samples of sediments and the digestive tract of coral reef fish. In sediments, MP abundances were recorded at 1,422 particles kg−1 dw sediment at station A, 1,185 particles kg−1 dw sediment at station B, and 59.8 particles kg−1 dw sediment at station C. The MPs in the fish digestive tracts were 726.17 particles kg−1 fish in station A, 827.99 particles kg−1 fish in station B, and 1670.42 particles kg−1 fish in station C.

Conclusion
MPs have contaminated sediments on Biawak Island, with higher abundances in areas of greater mangrove coverage. Also, coral reef fish from all three families were ingesting MPs, of which Lutjanidae was identified as the largest amount in their digestive tract.

Abstract
Connectives are a central means for creating a coherent discourse. The relationships between specific connectives, coherence relations and syntactic relations are complex for children to acquire. In this paper, we systematically compare the use of clause-initial connectives in written narratives by German-speaking children in fourth grade (10-year-olds, N = 32) and adults (N = 52). The overall use of connectives, the types of syntactic relations and coherence relations expressed and the connective types used as well as the relationships between syntactic relations, coherence relations and connective types are analysed. The results show that the groups expressed coherence relations with connectives equally often. Additive relations were the most frequent in both groups, but the children expressed temporal relations more often than the adults, who showed a larger diversity in the types of coherence relations. There was no difference in the overall use of subordination and coordination, but the adults expressed temporal relations more frequently with subordination. The children used adverbs to a greater extent than the adults. The connective da ‘then’ played an important role in the children’s expression of temporal relations, whereas the adults used a wider variety of different connectives to express different types of temporal relations. The results suggest that children in the fourth grade have not yet fully acquired an adultlike use of connectives in written narratives.

Актуальность исследования обоснована стратегической целью и практической важностью экономической кооперации и интеграции, развития культурного и политического сотрудничества в трансграничных регионах. В статье на основе анализа основных индикаторов социально-экономического развития приграничных территорий проведено районирование российско-казахстанского трансграничного региона. Выполненное исследование имеет комплексный характер и может служить основой для выявления различных рисков в сфере приграничной безопасности и анализа устойчивости российско-казахстанской границы. В результате исследования на пространстве российско-казахстанского трансграничного региона выделено четыре социально-экономических района: Западный, Центральный, Северный и Восточный, каждый из которых имеет свою специфику. При этом Западный и Северный районы вошли в группу с преобладанием более развитых регионов, тогда как Центральный и Восточный оказались менее освоенными и бедными территориями. Одновременно была выявлена закономерность: в более развитых социально-экономических районах наблюдается существенная асимметрия в показателях развития сопредельных приграничных территорий, при этом в менее развитых районах такая асимметрия практически отсутствует. В итоге полученные данные продемонстрировали высокую степень дифференциации социально-экономического развития территории российско-казахстанского трансграничного региона.
The study's relevance is substantiated by the strategic goal and practical significance of economic cooperation and integration, as well as the advancement of cultural and political collaboration between neighboring states. The research involves analyzing socioeconomic data of cross-border territories and zoning the Kazakhstan-Russia border area. This comprehensive study can serve as a foundation for detecting border security risks and examining the stability of the Kazakhstan-Russia border. The findings reveal the existence of four socioeconomic regions within the Kazakhstan-Russia cross-border area: Western, Central, Northern, and Eastern, each with its specifics. The Western and Northern regions are identified as having predominantly developed territories, whereas the Central and Eastern ones exhibit lower levels of development and economic prosperity. Interestingly, a consistent pattern emerged, indicating significant developmental asymmetry between adjacent border areas in the more developed territories, whereas such disparities were minimal in the less developed regions. Overall, the research findings demonstrate notable differences in socioeconomic parameters across the Kazakhstan-Russia cross-border region.

Published: September 2024

В статье предложен ряд многофакторных циклических моделей: для формирования вариантов макроэкономических параметров на уровне страны в целом; для трансляции макроэкономических параметров на уровень макрозон и регионов; для определения динамики и структуры ключевых показателей развития регионов (ВРП, инвестиции, денежные доходы населения и др.) в их взаимосвязях. Методологической основой для их построения послужили приемы когнитивного моделирования в сочетании с моделями тройной спирали. Предложена комплексная методика совместного использования этих моделей, направленная на обоснование приемлемых компромиссов в формировании ключевых параметров макроэкономического сценария и распределении результатов экономической деятельности между регионами в соответствии с его установками. Исследована когнитивная модель циклических взаимодействий в системе «регионы - федеральный центр - бизнес-структуры», позволяющая изучать отношения ее участников в системе прямых и обратных связей. Предложены схемы сводной оценки вклада каждого участника в общий поток трансакций между ними. Построены алгоритмы корректирования входных и выходных трансакций акторов в направлении сближения сводных оценок их активности. Результаты экспериментальных расчетов по модели подтверждают обоснованность отдельных предложений экспертного сообщества о желаемых изменениях в отношениях между регионами, федеральным центром и бизнес-структурами.
The article introduces a series of multifactor cyclical models aimed at achieving several objectives: shaping macroeconomic parameters on a national scale, translating these parameters to macrozones and regions, and outlining the dynamics and structure of key indicators of regional development (such as GRP, investment, and population income) in their interconnectedness. The construction of these models is underpinned by a methodological fusion of cognitive modeling techniques and triple helix models. The proposed comprehensive methodology combines these models, seeking to establish well-founded compromises in establishing key parameters for the macroeconomic scenario and the equitable distribution of economic results among regions based on predefined settings. Moreover, the study delves into a cognitive model of cyclic interactions within the “regions - federal center - business structures" system. This model allows for an examination of relationships among its participants within forward and backward linkages. It further suggests schemes for summarily assessing the contributions made by each participant to the overall transaction flow between them. We then develop algorithms for adjusting the input and output transactions of stakeholders to converge summary assessments of their activities. The experimental calculations conducted on this model validate certain suggestions from the expert community regarding desirable modifications in the relations between regions, the federal center, and business structures.
RUSSIA’S “CONTACT ZONE” WITH THE ASIA-PACIFIC REGION: THE FAR EAST
Authors: ИЗОТОВ Д.А. 
Published: September 2024

Дальний Восток России выполняет для национальной экономики функцию «контактной зоны» со странами АТР. При прочих равных условиях эффективная реализация потенциала российского Дальнего Востока возможна при снижении различных барьеров, сдерживающих торгово-экономические взаимодействия этого макрорегиона с зарубежными рынками. В текущих обстоятельствах увеличения экзогенных барьеров для национальной экономики в целом создаются предпосылки для отклонения торговых потоков Дальнего Востока России в пользу КНР, что генерирует негативные эффекты вынужденной привязки к одному зарубежному рынку.
The Russian Far East functions as a “contact zone" connecting the national economy with Asia-Pacific nations. Other things being equal, to fully unlock the potential of this region, it is essential to minimize the obstacles hindering its trade and economic engagement with foreign markets. Given the rising external barriers faced by the entire national economy, there is a growing possibility that the Far East of Russia may increasingly redirect trade toward China. This could lead to adverse consequences, as it would create an overreliance on a single foreign market.

Introduction. Postoperative hernias occur in 10–15% of patients. Considering the increase in the incidence of complications with the number of operations it is crucial to choose the optimal surgical technique in order to control the complications rate. This literature review summarizes previous studies on the treatment of postoperative hernias with mesh, comparing complication and recurrence rates according to surgical technique and mesh position. Methods. A thorough search was conducted on the PubMed database to retrieve literature on recurrence, chronic pain, haematoma, seroma, and surgical site infections rates. The results were meticulously summarised and used to confidently compare open and laparoscopic surgical techniques, as well as “sublay” and “onlay/inlay” mesh positions in more than 5-year follow-up. Results. The analysis was conducted on five publications that met the selection criteria. The results showed that laparoscopically treated hernias had lower recurrence and chronic pain rates, but more frequent haematomas. The presence of wound infections, BMI >30, treatment of recurrent postoperative hernias, multiple fascia lesions, enterotomy, larger abdominal wall defect and longer operative time were observed to be associated with higher recurrence rates. The position of the sublay mesh is associated with less frequent seromas, surgical infections, and recurrence compared to the onlay/inlay position. Studies have reported the superiority of large-pore lightweight polypropylene multifilament mesh over the same heavyweight mesh in managing postoperative hernias. Lightweight mesh is linked to a lower risk of hernia recurrence and higher compliance with the abdominal wall. Conclusion. Laparoscopic surgery is associated with lower rates of recurrence and chronic pain, but a higher frequency of haematomas. The sublay mesh position is associated with lower rates of seromas, surgical infections, and recurrence.
