Experimental study on the combustion characteristics of blends of sugarcane bagasse, Nanning meager-lean coal and petroleum coke
Authors: Xiong Ge , Zhang Yong , Jin Baosheng 
Published: December 2022

Abstract
Multi-fuel operation of the coal-fired boiler is considered as a promising option for boiler reformation to reduce carbon emissions while recycling solid waste. In this work, co-combustion characteristics of sugarcane bagasse, Nanning meager-lean coal and petroleum coke under different conditions were investigated in detail. And the interaction between raw materials was analyzed. Finally, the kinetic parameters were estimated by using the first-order response model. The results show that differences in petroleum coke content affect the appearance of weight loss peaks in the DTG curve. When the proportion of sugarcane bagasse is between 40 and 60%, the ignition and burnout characteristic indexes are particularly sensitive to variations in sugarcane bagasse content. Additionally, the interaction between the three raw materials is promoted as the proportion of petroleum coke is less than 40%. The kinetic analysis suggests that the increase of heating rate is conducive to the precipitation of volatiles, but there is an optimal heating rate for the fixed carbon combustion stage. The change of particle size combination has little effect on the activation energy of the volatile fraction combustion stage. This study provides a reference to ensure the stable and high-efficient operation of the coal-fired boilers during the multi-fuel combustion.
„Von dem einigen mitler Jhesu Christo“. Was man von Andreas Osianders Häresie noch lernen könnte
Authors: Sparn Walter 
Published: December 2022

Abstract
The first part of this contribution is devoted to my recollection of Christoph Schwöbel; both of us were pupils of Carl Heinz Ratschow, albeit at different times and in different roles. However, we both have been following a twofold counsel of our teacher, first not to restrict theology to value judgments but to strive for an ontology of Christian belief and second to work with a “Trinitarian definition of Christology”. Part two recounts the turmoil around Andreas Osiander in a turbulent time of a crisis of authority around 1550. He was in the end judged to be heretic and was excluded from “true” Lutheranism in the Formula of Concord 1577. Indeed, his doctrine of justification, influenced by humanistic Neoplatonism and even the Kabbala was contrary to the predominant position of the Wittenberg school. However, the crucial point was Osiander’s constellation of Soteriology, Christology and Trinitarian concept of God on a strictly exegetic basis. Part three offers a sketch of the interrelation of Osiander’s soteriological model of the believer’s ascension to God, his Christology of a mediator, and his concept of the divine Logos. In his time, Osiander in a way fulfilled Ratschow’s twofold counsel, in opposition to Christological functionalism and theological positivism. Even today, in view of the ecumenical debate on the doctrine of justification, his thought might give useful hints for revising the aforementioned tasks in fundamental theology.
Hegel’s Camel. From the History of Reconciliation to the Theory of Atonement
Authors: Saarinen Risto 
Published: December 2022

Abstract
The paper discusses the relationship between “atonement” and “reconciliation” in systematic theology, claiming that Hegel’s concept of reconciliation (Versöhnung) continues to influence contemporary English-speaking theology. It is argued that the so-called theories of atonement often tacitly assume “Hegel’s camel”, an idea consisting of three propositions as follows: (i) atonement is a consistent umbrella concept that pertains to the systematic explanation of the entire work of Christ, (ii) atonement contains both an overarching rational insight and a moral code of conduct that provide an apology for the truth of Christian faith, (iii) Anselm of Canterbury has seminal importance when this rational atonement is explained. The paper complements the author’s historical-critical discussion of “reconciliation” undertaken in St. Andrews Encyclopedia of Theology.
Welche Metaphysik braucht die Theologie? Mit einem Deutsch-Skandinavischen Rückblick
Authors: Aarhus Svend Andersen 
Published: December 2022

Summary
The critique of C. H. Ratschow and Knud E. Løgstrup against the existential theology of Bultmann serves as starting point for asking the question about the possibility of thinking metaphysically within theology. Various forms of critique of metaphysics are mentioned, in particular the one of Jürgen Habermas, who’s characterisation of Martin Luther’s theology as „fideistic“ is rejected. After a short presentation of the concept of time in Luther’s De servo aritrio the creation philosophy of Løgstrup is presented as a plausible theological metaphysics.
Wie ist die Welt zu erklären, wenn sie einer Erklärung bedarf?
Authors: Hermanni Friedrich 
Published: December 2022

Abstract
The essay explores in four steps the question of whether the world needs an ex­planation and how it is to be explained in the case of its need for explanation. The first step argues that the principle of sufficient reason is valid and may be applied to the world as a whole. The three following steps examine different possibilities of explaining the world. It is shown that neither an immanent nor an axiogenetic explanation is possible, but that only an ontotheological explanation has a chance of success.
Fabrication of high strength and functional GO/PVA/PAN ternary composite fibers by gel spinning

Published: December 2022

Abstract
Polyacrylonitrile (PAN) fiber is soft and comfortable, but its poor strength compared to other synthetic fibers has limited it wide range of applications. This study effectively improved the strength of PAN fibers by adding graphene oxide (GO) and polyvinyl alcohol (PVA) during PAN spinning. The composite fibers were prepared via gel spinning and subsequent hot drawing process. The results show that the PVA molecular chains embedded into the PAN molecular chain significantly improved the mechanical properties of the hybrid fiber. At the same time, the defect reduced the UV resistance and thermal stability of the hybrid fibers only when the PVA molecular was introduced in the PAN. Surprisingly, after the recomposition of GO in the above mixed polymer system, the interaction between the GO and matrix not only improved the mechanical properties of the fiber, but also enhanced the UV resistance and thermal stability. In addition, when the amount of GO was 0.3 wt%, the crystallinity of the GO/PVA/PAN composite fiber reached the maximum and the tensile strength was the highest. This strategic approach suggests an effective method to prepare graphene-based ternary composites fibers with high strength and novel functional characteristics.
China’s Official Finance in the Global South: Whatʼs the Literature Telling Us?
Authors: Ahmed Salma 
Published: December 2022

Abstract
In the last two decades, there have been exponential increases in Chinese loans and grants, particularly flowing to the Global South. The subsequent growth effects in the South have led to speculation about China’s development models that govern its official finance and the overall macroeconomic effects. Consequently, a considerable body of research has investigated how different Chinese development policies affect the allocation patterns and outcomes in the Global South. This paper critically reviews related scholarly works, emphasising empirical literature. It identifies that the One China Policy is unanimously the most important strategy in explaining Chinese funding, although this policy tool may not be linked to trade with China and its humanitarian assistance. Chinese finance undermines efforts to promote good governance and contributes to political extortion and environmental degradation in recipient countries by not imposing governance reform conditionality on official financing. However, this argument must be carefully weighed against the positive impact of Chinese finance on health and economic growth, among other benefits. Despite intense research efforts, further research is still needed to understand vulnerabilities associated with China’s development models. The information conveyed by the review will be of interest to foreign aid spectators seeking to learn from China’s experience.

Published: December 2022

Abstract
With the proposal of a dual carbon goal in China, shallow geothermal energy as a kind of clean energy has been gradually promoted and applied. At the same time, more and more geotechnical workers have gradually paid attention to the influence of temperature on the mechanical characteristics of rock and soil mass. Existing experimental research has shown that the thermodynamic behavior for cohesive soil such as clay and silt is relatively mature but is relatively less mature for noncohesive soil, especially for sand. Based on the hollow cylinder triaxial specimen, a series of temperature-controlled triaxial tests have been carried out on saturated Fujian sand under different initial relative density and temperature conditions to capture the change of axial and volumetric strains for saturated sand specimen with increasing temperature. In addition, a bulk volumetric coefficient of thermal expansion of the sand specimen has been put forward, and the relationship between this coefficient and initial relative density also has been established. Then, the thermal deformation mechanism of saturated sand specimen has been revealed. After that, based on the test data during undrained shearing, the stress–strain relationship, deviatoric stress, and pore water pressure at peak state for loose and medium-dense saturated sand specimens have been explored, which can be used to provide some theoretical guidance for shallow geothermal energy and other temperature-related engineering applications.

Foods that contain high levels of fat can cause hyperlipidemia, which is one of the triggering factors for non-alcoholic fatty liver disease. Neem leaves contain flavonoids, alkaloids and tannins which have the ability to act as hepatoprotectors. This study aimed to determine the Liver Histopathology of Rats Induced by High-Fat Feed After Giving Neem Leaf Ethanol Extract. Twenty-four the male white rats (Rattus norvegicus L.) were divided into 6 treatment groups, namely: normal control (P0); negative control (P1: given high-fat diet); P2 treatment (P1+ 8 mg/200gBW simvastatin); and P1+ the dose of neem leaf ethanolic extract of 75; 100; and 125 mg/200gBW (P3; P4; and P5). Fixation process with 10% Neutral Formalin Buffer (NFB) solution. Liver histopathological preparations were made by paraffin method and Hematoxylin-Eosin staining, histopathological observations with a 400x magnification microscope. Liver histopathology was analyzed descriptively, homogeneous and normally distributed data of liver weight and hepatocyte diameter were analyzed statistically using ANOVA followed by Duncan's test with a significance level of 5% using SPSS 16.0 software. The results showed that the administration of ethanolic extract of neem leaves could improve the liver histology structure. From this study it was concluded that the ethanolic extract of neem leaves can be used as an alternative hepatoprotector.

Nepenthes mirabilis (Lour) Druce is a rare ornamental plant and has high economic value so it needs to be preserved. This study aimed to analyze effect of sucrose and BAP concentrations and their optimal interactions in the in vitro multiplication of Nepenthes mirabilis. Explants in the form of in vitro plantlets from Laboratory of Plant Tissue Culture, Department of Biology, Semarang State University. The treatment was carried out by adding sucrose and BAP to murashige skoog (MS) media with various concentrations. The treatments were arranged in two factor completely randomized design with four replications. Plantlets were planted in the treatment medium for 10 weeks, then every week the growth of shoots and leaves of N. mirabilis was observed. The data were analyzed by two-way analysis of variance and Duncan's test. The results showed that concentration of sucrose, BAP, and their interactions affected the growth of explants. Plantlets grown on media with sucrose concentration 20 g/l produced the highest number of shoots, media with concentrations BAP 3 and 2 ppm produced the highest number of shoots and number of leaves. Medium ½ MS with varying concentrations of sucrose 20 g/l with 3 ppm BAP and sucrose 20 g/l with 2 ppm BAP resulted in the highest growth in the number of shoots and number of leaves. The composition of this medium can be used for the multiplication of N. mirabilis.

Published: December 2022

Whole-cell biocatalysis using Antarctic bacteria is presently hampered by a lack of genetic information, limited gene tools and critically, a poor range of cultivation conditions. In this work, biological engineering strategy was employed for developing Pseudomonas extremaustralis, a metabolically-versatile and biopolymer-producing Antarctic bacterium, as a new whole-cell biocatalytic host. For this purpose, gene cloning and plasmid construction were carried out for overexpression of furfural reductase (FucO), an industrially-important enzyme for degradation of toxic furfural compound commonly found in lignocellulosic biorefinery. FucO gene from Escherichia coli BL21 was cloned in pJM105 plasmid and transformed into competent cells of P. extremaustralis to generate a biologically-engineered pFucO strain. For functional characterization of the enzyme, furfural reductase activity was assayed, where the P. extremaustralis pFucO strain exhibited increased furfural reductase activity of about 15.6 U/mg, an 18.8-fold higher than empty plasmid-carrying control pJM105 strain (0.83 U/mg). Furfural detoxification activity using whole cells was also determined by which the overexpression of FucO led to increased tolerance and cell growth with an OD600 value of 5.3 as compared to the control pJM105 strain that was inhibited with 10 mM furfural during 48-hour cultivation. Therefore, the findings obtained in this study successfully demonstrated the development of P. extremaustralis as biocatalytic host for the production of recombinant furfural reductase. The bioengineering would serve as a modular biotechnological platform for polar strain and bioproduct development tailored towards industrial biotechnology applications.

Background. Persistently high incidence of cervical cancer in Russia and significant number of cases detected in the late stages necessitate the improvement of secondary prophylaxis of this disorder.Aim. To assess risk factors for recurrent high-grade cervical intraepithelial neoplasia (CIN2+) (high grade squamous intraepithelial lesions, HSIL) after cervical conization.Materials and methods. This study included 62 patients with recurrent HSIL treated in Novosibirsk Regional Clinical Oncology Dispensary, E. N. Meshalkin National Medical Research Center, “Zdorovye” LLC, “Avismed” LLC, Tomsk National Research Medical Center of the Russian Academy of Sciences, and Federal Research and Clinical Center for Specialized Medical Care and Medical Technologies, Federal Biomedical Agency of the Russian Federation in 2017–2021. We analyzed patients’ human papillomavirus (HPV) status, performed repeated examination of excised tissue specimens to evaluate the severity of lesions and resection margins, as well as immunohistochemical examinations. We found that mean time to cytologically confirmed recurrent HSIL was 16.0 ± 5.6 months. All patients were HPV-positive. Repeated histological examination demonstrated that 18 samples had positive resection margins or endocervical crypt involv ement. Fifty-seven samples had positive staining for p16 at immunohistochemical examination; 46 samples had Ki-67 >30 %, which indicated high risk of recurrence. Treatment of patients with recurrent HSIL included repeated excision up to healthy cervical tissues, followed by intravaginal therapy with Cervicon-DIM 100 mg twice a day (for 3 months). Follow-up examinations after 18.0 ± 6.2 months on average showed no HPV persistence and no HSIL recurrence.Conclusion. Endocervical crypt involvement along the primary resection margin, underestimated severity and depth of lesions (at the first surgery), and persistence of HPV infection are the main risk factors for recurrent cervical dysplasia or carcinoma in situ. Combination treatment that includes additional excision with a subsequent course of Cervicon-DIM is sufficient and effective.

Approximating Constant-Q Seismic Wave Propagations in Acoustic and Elastic Media Using a Cole–Cole Model

Published: December 2022

ABSTRACT
Seismic wave propagation in the Earth’s interior inevitably encounters attenuation and dispersion effects, which usually can be represented by a constant-Q model. However, solving the constant-Q wave equations formulated by fractional Laplacians is computationally intensive. Alternatively, the Cole–Cole model provides an optimal description of seismic attenuation. Because of the fractional time derivatives of both stress and strain in the expression, this method exhibits good adaptability and flexibility. In this article, we investigate the performance of the Cole–Cole model to approximate constant-Q behaviors with different fractional orders in acoustic and elastic media. The phase velocity and quality factor are compared to determine an optimal fractional order. After that the Cole–Cole model can be easily represented by the other three parameters (i.e., relaxed modulus, minimum angular frequency, and minimum quality factor), which are similar to the constant-Q theory (reference modulus, reference angular frequency, and frequency-independent quality factor). The first-order viscoacoustic and viscoelastic wave equations are derived to implement seismic wavefield simulations by combining conservation equation and stress–displacement relation. Furthermore, a time-domain algorithm is developed to solve the wave equations based on the Grunwald–Letnikov approximation and finite-difference scheme. Numerical modeling results calculated by our proposed method have good consistencies with the reference solutions from the constant-Q theory, suggesting that a small fractional order can well approximate the constant-Q outputs in a broad frequency band.
