Murburn concept in cellular function and bioenergetics, Part 2: Understanding integrations-translations from molecular to macroscopic levels
Authors: Manoj Kelath Murali , Jaeken Laurent , Bazhin Nikolai , Tamagawa Hirohisa , Gideon Daniel Andrew , Kavdia Mahendra
Published: July 2023

Thermogenesis, electro-chemical physiology (ECP) electro-mechanical activities (EMA) are fundamental facets of cellular functioning that are associated with powering, coherence, homeostasis, sensing and response to stimuli. The classical Hodgkin-Huxley-Katz purview of ECP is derived from Nernst-based foundations for dilute solutions, whereas cellular milieus are mostly highly packed colloidal coacervates, with various types/levels of macromolecules-ions interactions and ordering of water. It has also been established that trans-membrane potential (TMP) manifestation can also be affected by adsorption of ions and effective charge separation (ECS, 1e processes), necessitating the questioning and expansion of classical purviews. Further, we have demonstrated that the traditional explanation of electrogenic/stoichiometric and vitally deterministic bidirectional pumping/channelling of ions by membrane proteins (such as Na,K-ATPase) as the rationale for resting/dynamic TMP variations is untenable. In stark contrast, the murburn purview of ECP-EMA acknowledges the complexity and discretization of water-ions-macromolecules organization within the cell, and does not solicit selective ion-pumping or TMP-based powering/propagation rationales. Herein, we summarize the murburn rationale for the molecular to macroscopic integration of processes such as thermogenesis, kinetic Na-K differentiation at the cell membrane, visual signal transduction and neuronal impulse relay, Complex V mediated mechano-chemostat function, flagella-based motility, etc. and discuss the alteration of cellular volume/tenor in muscle cell contraction. We assert that the membrane-embedded proteins/enzymes cannot use ATP to work against the natural laws of physics. Therefore, the classical perception of membrane-based ion pumps must be jettisoned to make way for the thermodynamics-friendly murburn purview.
To what extent is using wind renewable energy justified: The Scientific Environmental Considerations
Authors: Bansal Bhavya
Published: July 2023

With the increased awareness of the effects of global warming, there is a large push to start using greener fuel sources to help keep our earth as healthy as possible. As more people decide to look for sustainable energy sources, research is being done on the overall effects of using wind energy as an alternative to fossil fuels. While using renewable sources such as wind energy are certainly ways to generate power with less pollution, those in opposition recognize the effects that these energy sources are having on the environment. While opponents argue that wind energy has a significant negative impact on the environment, proponents have investigated ways to implement practical solutions to many issues brought up with this relatively clean energy source. The question is, is there strong enough scientific evidence to consider the use of wind renewable energy an effective choice?
Does Mud Always Stick? No Evidence for the Continued Influence of Misinformation on Person Impressions
Authors: Mickelberg Amy , Walker Bradley , Ecker Ullrich K. H. , Howe Piers , Perfors Andrew , Fay Nicolas
Published: July 2023

Despite robust evidence that misinformation continues to influence event-related reasoning after a clear retraction, evidence for the continued influence of misinformation on person impressions is mixed. Across three experiments, we investigated the impact of person-related misinformation and its correction on dynamic (moment-to-moment) impression formation. Participants iteratively formed an impression of a protagonist, “John”, based on a series of behaviour descriptions, including misinformation that was later retracted. Person impressions were recorded after each behaviour description. As predicted, we found a strong effect of information valence on person impressions: negative misinformation had a greater impact on person impressions than positive misinformation (Experiments 1 and 2). Furthermore, in each experiment participants fully discounted the misinformation once retracted, regardless of whether the misinformation was positive or negative. This was true even when the other behaviour descriptions were congruent with (Experiment 2) or causally related to (Experiment 3) the retracted misinformation. Thus, we found no evidence for the continued influence of retracted misinformation on person impressions. Our findings help to address some of the discrepant findings in the literature, suggesting that following a clear retraction, person-related misinformation can be effectively discounted, at least for the scenarios considered in this study.
Digital Single-Session Interventions for Youth Mental Health
Authors: Jans Laura , Sotomayor Ian , Schleider Jessica L.
Published: July 2023

The mental healthcare system is overburdened and incapable of meeting the current need for services. This need-to-access gap is unlikely to be filled by dominant treatment delivery models, which often require multiple sessions of face-to-face therapy delivered by highly trained professionals. In this chapter, we overview how digital, self-administered single-session interventions (SSIs) can serve as a tool to help narrow the treatment gap and increase accessibility of evidence-based care. We review the state of the evidence on digital SSIs for youths and young adults and highlight trends among effective interventions. Lastly, we conclude with a discussion on maximizing the scalability and accessibility of digital SSIs.
Psychological interventions for children with chronic physical conditions: A systematic review assessing the role of emotional and cognitive processes
Authors: Kaemmerer Mareike , Jeitani Céline , Verwimp Cara , Lahaye Magali , Luminet Olivier
Published: July 2023

Pediatric chronic physical conditions (CPC) can lead to emotional and cognitive difficulties. Although both types of processes play a major role in child development, no systematic review in the pediatric psychology has investigated the effectiveness of interventions on these two processes concurrently. To address this gap, this review focused on the role of emotional and cognitive processes as predictors of the effectiveness of psychological interventions for children with CPC.Studies were included if they assessed at least one emotional/cognitive process (e.g., coping/attention. We included RCTs with children (8-12 years) with a CPC (e.g., diabetes, asthma), which implemented a psychological intervention. This study is registered in Prospero (CRD42021233505).We identified ten studies which implemented either Cogmed or a coping intervention (e.g., Coping Skills Training). Cogmed interventions showed some improvements in working memory, but the effects are not homogeneous across studies despite the similarity of methodologies. Coping interventions showed little effect on emotional processes or overall psychological health variables and were not more beneficial than control groups. No study trained or assessed both emotional and cognitive processes.The review shows limitations in the current literature regarding the efficacy/evaluation of psychological interventions. Underlying processes are assessed by very few studies which limits the possibility of further understanding the interventions’ action mechanisms. Systematically including emotional, cognitive and other underlying processes in intervention studies could help to better adjust interventions to children with CPC.

Authors: Zetsche Ulrike , Neumann Pauline , Bürkner Paul - Christian , Renneberg Babette , Koster Ernst H. W. , Hoorelbeke Kristof
Published: July 2023

Objective: Rumination is a well-known risk factor for the onset and recurrence of depressive episodes. Depressed individuals with a tendency to ruminate have been found to exhibit deficits in updating the contents of working memory. Thus, working memory training targeting updating-specific cognitive control processes may bear the potential to reduce ruminative tendencies. This registered clinical trial (ClinicalTrials.gov/NCT03011216) examined the effect of training cognitive control on rumination in the daily lives of clinically depressed individuals.Methods: Sixty-five individuals with a current major depressive disorder were randomized to 10 sessions of either cognitive control training (N=31) or placebo training (N=34). Primary outcome measures were the frequency and negativity of ruminative thoughts in the daily lives of participants assessed by a 7-day experience sampling procedure prior to training, after training, and at 3-months follow-up. Secondary outcomes were depressive symptoms, depressive mood, and level of disability.Results: Cognitive control training led to stronger improvements in the trained task than placebo training. There was no transfer of the training effect to a novel cognitive control task. Cognitive control training did not lead to a greater reduction in daily rumination frequency, negativity of ruminative thoughts, or the negative influence of rumination on subsequent affect than the placebo training. There was no training-specific effect on participants' depressive symptomatology or level of disability.Conclusions: Results join in a picture of mixed findings regarding the effect of cognitive control training on rumination. Future research has to identify determinants of beneficial training effects.

The Concept of Danda in the Dharmasastra
Authors: Sondhi Sunil
Published: July 2023

The idea of legal culture has had an important place in major recent debates about the nature and aims of law. The concept of legal culture means that law should be treated as embedded in the broader culture of society. In a sense, law is culture. Concept of legal culture encompasses much more than the professional juristic realm. It refers to a more general consciousness or experience of law that is widely shared by those who constitute a nation. Culture is fundamental — a kind of lens through which all aspects of law must be perceived, or a gateway of understanding through which we must pass so as to have any genuine access to the meaning of law in society. Cultural concepts of law that emerge out of the several frames of reference in the dharmasastra, the republican governments in ancient India, and the constituent assembly debates enable us to view the law in India in an integrative perspective that is closer to Indian cultural tradition. The innovative value of historical and sociological approach lies in its unifying vision of the theological, cultural and positivist aspects of the concepts of law in Indian tradition. A holistic concept of law including both ethical and legal perspectives seems to provide a more realistic picture of Indian legal culture. A juridical system that does not correspond to the social and cultural sensitivities of a society can not be owned by the people as their system but will be seen as something foreign and imposed. Without a conducive social and cultural conceptualization mere formal law cannot create willing legal and moral obligation.
Longitudinal associations between use of cardiovascular medications and cognitive function in three longitudinal studies of aging in Sweden
Authors: Huda Nazifa Nawal
Published: July 2023

Introduction: There is no curative treatment available for cognitive impairment. Some cardiovascular (CV) medications have been associated with attenuating the risk. The associations however are inconclusive.Aim: To determine the longitudinal associations between beta blockers, calcium channel blockers, and lipid lowering drugs and cognitive function.Methods: The study included 1,094 individuals with 3,995 repeated measurements, from the harmonization of three registry cohorts, from 1986 to 2014. The information about taking cardiovascular medications were self-reported. Cognitive function abilities were presented as a score derived from in-person cognition testing including four distinct types of cognitive tests. Conditional generalized estimating equations (cGEE) were used to estimate the associations between medications’ use and cognitive function. Interaction and stratification analysis by sex were performed.Results: In the first assessment, the mean age of the participants was 70.59 years. In the multi adjusted cGEE model, beta blockers (beta [β]: 0.67, 95% confidence interval [CI]: 0.19 to 1.15) and lipid modifying medications (β: 0.80, 95% CI: 0.29 to 1.31) were associated with higher mean cognitive function score. The results from calcium channel blockers were inconclusive. The use of lipid modifying agents were associated with higher mean cognitive function for men, and the use of beta blockers were associated with higher cognition for women. However, the likelihood of sex modifying the association was inconclusive.Conclusion: This study suggests that beta blockers and lipid modifying agents are associated with higher cognitive function. Precaution should be taken while interpreting the results as the associations might still be confounded by indication.

The Municipal Government of Bekasi has known risk management through elements of risk assessment since 2011, but until now in its implementation it has not yet had an ideal strategy so that the hope of creating good governance has not been fully achieved. As one of the strategic needs in improving organizational performance, risk management is needed in optimizing the use of resources owned by the organization through rearranging the governance system by applying the principles of transparency and accountability. This study aims to determine the factors that have caused the implementation of risk management in the Bekasi City Government to not run effectively and efficiently so that a risk management strategy design is needed that is in accordance with the characteristics of local wisdom in improving the performance of agencies in the Bekasi City Government. The method used in this study is a qualitative case study method with purposive and snowball sampling techniques. As for data collection techniques through in-depth interviews with data processing using triangulation (combined) and is inductive. The final results of this study indicate that risk management must be managed based on the regulation of the Deputy for Supervision of Regional Financial Management No. 04 of 2019 concerning guidelines for risk management in local governments. Performance accountability is the obligation of government agencies to be accountable for their performance achievements, which are set forth in a report through SAKIP. to improve government performance accountability, risks from programs and activities must be managed through good and correct risk management. The implementation of Risk Management is influenced by external factors, namely the OPD within the Bekasi City Government and internally, in this case the Regional Inspectorate Institution; in terms of human resources, budget and other facilities and infrastructure.

Authors: Zhao Mu-Zi , Lehman Dawn E. , Zhang Xin , Roeder Charles W.
Published: July 2023

The accuracy of the shear resistance design equation for concrete-filled steel tubes (CFSTs) is crucial to ensure the safety of CFST structures. However, the current design equations underestimate the test data, and cannot accurately predict the relative shear resistance of the steel and concrete fill. To solve this problem, this paper developed an advanced finite element model in the LS-Dyna program, which was validated using experimental results of CFST members failing in shear. A systematic parametric study was then conducted. The result showed that the contribution of the steel increased significantly with the strain-hardening ratio (F_u/F_y) while the contribution of concrete fill was greatly influenced by the internally reinforced ratio (ρ_int) and axial load level (P/P_0). These predictions were combined with the experimental results to develop a more accurate and reliable design expression for the shear strength of circular CFSTs.

Published: July 2023

Due to rapid industrialization and economic growth, the generation of construction and demolition waste (CDW) from the activities of demolishing buildings is increasing in Vietnam. The Vietnamese Government has regulations on recycling and collecting CDW for reuse, recycling to environmental protection through Circular No. 08/2017/TT-BXD in 2017, and Directive 41/CT-TTg in 2020. Waste concrete fines (WCF) are generated during demolishing process or crushing of CDW materials. To save natural resources and increase the recycling rate, a disc pelleting technology has been used to recycle WCF. The pellet machine has a disk with 1.5m of diameter and 0.3m of depth; tilted at an angle of 55 degrees and the rotation speed from 15 to 22 rpm; the capacity is 0.5 to 0.8 tons per hour. This paper presents the results of pelletizing WCF research to produce synthetic aggregate (SA). The SA pelletized by WCF and cement had an apparent specific gravity of 2.45 – 2.55 g/cm3, a dry bulk specific gravity of 1.85 – 1.95 g/cm3, a crushing value of 19.2 – 29.9%, a LA (Los Angeles) value of 23 – 33% and water absorption around 13.2%. The mechanical properties of SA meet the requirement of TCVN 11969:2018, recycled aggregate type II for concrete.

Vietnam experiences increasing droughts throughout the dry season due to climate change, global warming,and human-caused activities like urbanization and deforestation. Drought hazard significantly impacts socioeconomic, agriculture, and the environment; it directly threatens human lives, livelihoods, food security, and environmental degradation. It is essential to have a drought assessment map to assist in developing and implementing strategies to combat drought. Space remote sensing technology development has enabled efficient and cost-effective monitoring and evaluation of droughts on a large scale, surpassing the capabilities of ground-based observations. This research uses remote sensing technology to monitor and assess the severity of the drought in the Bac Binh district, Binh Thuan province. We analyzed the Temperature Vegetation Dryness Index (TVDI) using multi-temporal Landsat 8 satellite data for the severe drought events in 2014, 2017, and 2020. The results indicate a significant increase in the percentage of land area affected by drought, from 50.74% in 2014 to 66.23% in 2020. The obtained maps provide valuable visual data to relevant agencies, assisting with planning preventative measures and mitigating future drought risks.

Published: July 2023

Ukraine has tremendous potential for renewable energy production. With sources such as solar and wind, coupled with a strong industrial sector (primarily in metallurgy and chemical industry), Ukraine is well positioned to play a significant role in large-scale production of green hydrogen. This is particularly relevant today with the global shift towards green hydrogen production.Currently, Ukraine’s hydrogen production stands at approximately 360,000 t/year, which is primarily used for ammonia production. While this only accounts for 0.5% of the total global demand, with technological advancement and investment, Ukraine could significantly increase its hydrogen production capacity.Central European directives, in particular the European Commission’s “Energy System Integration. Hydrogen” and the “Green Hydrogen for a European Green Deal: A 2х40 GW Initiative”, identify Ukraine as a strategic partner in the development of renewable hydrogen. These strategic documents envision the construction of up to 10 GW of electrolysis capacities in Ukraine by 2030, intended for renewable hydrogen production. About 1.8 GW of this capacity is for the domestic market, primarily for the production of green ammonia, a critical commodity for the agro-industrial complex.Implementing these initiatives could significantly reduce Ukraine’s energy dependence on imported fuels and significantly reduce harmful emissions, in line with international efforts towards sustainable development. This transition could play a pivotal role in the decarbonization of Ukraine’s economy and contribute to its national energy security. However, realizing this requires significant advancement in hydrogen production technology and infrastructure.This includes infrastructure for efficient storage and transportation of hydrogen. Furthermore, it requires government policy support, namely investment incentives, research and development subsidies, and assistance in the infrastructure development. Thus, the prospects for the evolution of hydrogen economy in Ukraine are indeed attractive. The production of green ammonia is an important step in this direction. Under favourable conditions, it is possible to produce hydrogen for consumption both domestically and for export to European Union countries.
