Abstract
Biogas production from sewage sludge can be valued in different scenarios of energy usage such as the electricity, heating, and transportation system. Improving the energy production value is the main reason for using different ways such as alkaline pretreatment and nanoparticles (NPs). This investigation uses life cycle assessment (LCA) for evaluating the biomethane production from co-digestion of sewage sludge and wheat straw in the presence of polypyrrole Fe3O4 nanoparticles (0, 20, 40, 60, and 80 mg) and NaOH alkaline pretreatment (0 and 5 mg) at mesophilic anaerobic digestion along with optimization for sustainable biomethane production. Results indicated that retention time (RT) and NaOH concentration had a significant effect on biomethane production. But, the effect of NP concentration on biomethane production was not significant. Also, the maximum biomethane production was obtained by NP40Na0 (about 50% higher than the control). On average, adding the NaOH and NPs improved the biomethane yield by about 25–40% vs in comparison with the control. The maximum biogas production yield was related to NP40Na0 with an enhancement of about 35% in comparison with the control. On average, adding nanoparticles and NaOH alkaline pretreatment improved the biogas production by about 10–20% in comparison with the control. Sustainable biomethane production can be obtained at an NP concentration of 50.24 mg and NaOH concentration of 24.04 mg, which increased the biomethane production by about 198%, and reduced human health, ecosystem quality, climate change, resources, and economic cost by about 87, 86, 92, 95, and 87%, respectively, in comparison with the control.

Abstract
Manual harvesting of sugarcane requires skilled labourers, as improper harvesting leads to a significant loss of yield. Therefore, it is necessary to move towards designing a system capable of harvesting sugarcane on smallholdings, with high harvesting efficiency. This study aims to determine some physico-mechanical properties of sugarcane stalks related to harvester by making a comprehensive analysis of the compressing, bending, and shearing properties of sugarcane stalks. These properties were measured at three moisture content levels at three positions (base, middle, and top) of the stalk with three sugarcane varieties (G.T.54-9, IK 76-66, and HAO3-55-24). The different moisture contents were fresh stalk, after 7 days, and after 15 days. The values of different content with different varieties were (70.3, 42.1, and 23.2%), (68.7, 61.3, and 42.7%) and (66.4, 48.6, and 30.5%), respectively. The physico-mechanical properties of stalks were measured in terms of diameter, length, fresh mass, moisture content, sugarcane stalk bulk density, compression stress, shear stress and bending stress at three different positions (top, middle, and base).The most important results showed that the decreasing stalk moisture content of three sugarcane varieties led to an increase in compression, shear, and bending stresses.

Abstract
The publication is focused on the anisotropic properties of products of additive manufacturing using a Fused Filament Fabrication technology (FFF). Five different materials used in technical practice were tested. These materials are PLA (polylactic acid), PETG/CF (polyethylene terephthalate-glycol with carbon fibre, composite material), PETG (polyethylene terephthalate-glycol), ABS (acrylonitrile butadiene styrene), and ASA (acrylic styrene acrylonitrile). Mechanical properties are verified by tensile testing according to ASTM D638. Testing is complemented by a digital image correlation method to locate the areas with the highest load transfer. The results have shown clear anisotropic properties of the test specimens. Anisotropic mechanical properties were also confirmed by digital image correlation (DIC).

Published: August 2023

Abstract
The presented work investigates the degradation of an ecological energy carrier in the form of changes in its properties, which was subjected to dynamic loading through a test device in laboratory conditions. The primary goal was to describe the degradation process itself in terms of obtained data through the analysis of kinematic viscosity, water content, acidity number, and X-ray spectrometry. The process was focused on monitoring the values of increase in contaminants and monitoring the values of changes that occurred in case of additives. The ecological energy carrier in the form of transmission-hydraulic fluid was cyclically loaded in a time interval of 200 working hours, while a time interval of every 25 working hours was used when a sample was taken and subsequently analysed. From the obtained data, it can be concluded that during the degradation process, there were no significant changes in the observed properties of the liquid, chemical composition, or additives. For this reason, further measurements of the ecological energy carrier were subsequently carried out. The influence of the given energy carrier on the change in the flow rate of a new type of hydraulic pump with external gearing was also monitored.
The changing role of a video-on-demand service in the strategies of public service media: A production study of Danish TV 2 Play and its impact on the production culture of the schedulers, 2016–2022
Authors: Bruun Hanne 
Published: August 2023

Abstract
This article highlights and discusses the main findings from three different media production studies (2016, 2019, and 2022) investigating the changing production culture of the schedulers in public service media. The inclusion of a broadcaster video-on-demand (BVoD) service in the broadcaster's portfolio affected the production culture. First, the article argues that profound changes happened to the organisational framing of the BVoD service's status and its impact on the production practices. Second, the article shows the BVoD service's impact on the content priorities among the schedulers at TV 2 in Denmark and third, how the public service branding of TV 2 became more explicit in the production culture. However, across these three points of impact and the shifts in the strategic focus at TV 2, the business model at TV 2 and its interplay with the public service obligations runs as an undercurrent.

Background:
The global coronavirus disease-19 (COVID-19) pandemic has resulted in procedural delays around the world; however, timely and aggressive surgical resection for malignant brain tumor patients is essential for outcome optimization. To investigate the association between COVID-19 and outcomes of these patients, we queried the 2020 National Inpatient Sample (NIS) for differences in rates of surgical resection, time to surgery, mortality, and discharge disposition between patients with and without confirmed COVID-19 infection.

Methods:
Patient data were taken from the NIS from April 2020 to December 2020. COVID-19 diagnosis was determined with the International Classification of Diseases, Tenth Revision, Clinical Modification code U07.1.

Results:
A total of 30,671 malignant brain tumor patients met inclusion criteria and 738 (2.4%) patients had a confirmed COVID-19 diagnosis. COVID-19-positive patients had lower likelihood of receiving surgery (Odds ratio [OR] 0.43, 95% confidence interval [CI] 0.29–0.63, P < 0.0001), increased likelihood of mortality (OR 2.18, 95% CI 1.78–2.66, P < 0.0001), and increased likelihood of non-routine discharge (OR 1.25, 95% CI 1.13–1.39, P < 0.0001). Notably, COVID patients receiving surgery were not associated with surgical delay (P = 0.17).

Conclusion:
COVID-19 infection was associated with worse patient outcome in malignant brain tumor patients, including decreased likelihood of receiving surgery, increased likelihood of mortality, and increased likelihood of non-routine discharge. Our study highlights the need to balance the risks and benefits of delaying surgery for malignant brain tumor patients with COVID-19. Although the COVID-19 pandemic is no longer a public health emergency, understanding the pandemic’s impact on outcome provides important insight in effective triage for these patients in the situations where resources are limited.

Purpose: The research is conducted to analyze the performance of scientific publications by lecturers in private higher education in Garut District-Indonesia with the values of spirituality and job satisfaction as mediating variables.

Theoretical Framework: Resource-Based Theory (RBT) is employed to elucidate the correlation between work spirituality, job satisfaction, and the lecturers performance of faculty members in publications.

Design/Methodology/Approach: The research method used is descriptive and causalitas. Data collection was carried out by distributing questionnaires to a sample of 157 people. Before being analyzed, the data was tested for its validity and reliability. Furthermore, data analysis was performed using statistical software.

Findings: The analysis result shows that the performance of scientific publication of lecturers is influenced by spiritual values in the workplace, such as calmness of mind when working, the outcome of work meeting the organization's expectations, the usefulness of the work that can help others, and also supported by job satisfaction, such as career satisfaction, having a pleasant job, and supportive colleagues.

Research/Practical & Social implication: Practically, in this study, the model can function as a significant management tool in the world of education, especially higher education, to increase the sustainability of competitive advantage that has the potential to affect organizational performance. Employee performance is also an important factor in supporting organizational success. Thus this can be an attention for the organization to improve the performance of lecturer publications.

Limitation: This research has several limitations that need to be taken into account and can provide direction for future research; because this research only analyzes from the perspective of private universities, so in the future it can also be from the perspective of state universities. The sample size is also only taken from one university only, so future research can be expanded again from various universities.

Originality/Value: Although many studies have been conducted on lecturer performance, there are still few that analyze the scientific publication performance from the values of work spirituality, especially in private higher education, so this research is considered to have uniqueness especially in Indonesia.

Decentralization in Neopatrimonial Democracy: Advantages, Disadvantages and the Path to Potential Peace
Authors: Makhmutova E. V. , Okumbekov R. S. 
Published: August 2023

In many authoritarian countries of the world, rulers proclaim that the current regime is a model of liberal democracy. Its most significant flaw, however, is that it does not actually exist. This discrepancy between the supposed democratic leadership and reality is due to the neopatrimonial nature of the current political systems. Neopatrimonialism appears to be a hybrid model in which state structures, laws, and rules formally exist but are overridden by informal politics, networks of patronage, kinship, and tribalism. Rather than being organized according to merit, social functions, or administrative rank, the neopatrimonial regime finds its stability in bonds of loyalty to those at the top of the political hierarchy. Often, decentralisation reforms are initiated to overcome this crisis and stalemate. Their result is not always unambiguous, and the resulting effect corresponds to widely advertised expectations. In this context, this study examines the peculiarities of decentralisation reforms and their results in the countries with neopatrimonial democracy. Special attention is paid to the advantages and disadvantages of delegating part of state powers and authority to the local level, as well as its possibilities in achieving peace and resolving conflicts. The results suggest that, ideally, decentralisation generally contributes to an inclusive world where different groups can access power and are included in governance. In practice, however, this result is not always achieved because of the weak institutionalisation of the party system, the lack of transparency in government, and an underdeveloped civil society. The paper examines in detail the specifics of neopatrimonialism in its theoretical and methodological dimension. In addition, emphasis is placed on the potential of decentralisation to contribute to the peaceful resolution of conflicts in a country or — given weak social and political institutions, on the contrary, to increase uncertainty and the threat of military confrontation. A positive example of decentralisation in a neo-patrimonial democracy is seen in the Republic of Kazakhstan, where reforms aimed at changing the contour of the political system, namely constitutional changes affecting, among other things, the powers of the president, were introduced in 2022–2023. The successes in the implementation of constitutional reform in the country are outlined, and the key foundations of successful delegation of powers and separation of powers are highlighted. Using Kazakhstan as an example, the experience of democratisation through the prism of political and socio-economic transformations is examined. The conclusions of the article contain the thesis that depending on the totality of circumstances, peculiarities of political culture, the structure of the power apparatus, etc., the process of decentralisation in neopatrimonial regimes can be both effective and weakly expressed, aimed at strengthening the concentration of power by the ruling elite.
