New polysilsesquioxane (PSQ)-based CO2 separation membranes with succinic anhydride and monoalkylurea units as thermally degradable CO2-philic units were prepared by the copolymerization of a 1:1 mixture of [(3-triethoxysilyl)propyl]succinic anhydride (TESPS) or [(3-triethoxysilyl)propyl]urea (TESPU) and bis(triethoxysilyl)ethane (BTESE). The succinic anhydride and monoalkylurea units underwent thermal degradation to form ester and dialkylurea units, respectively, with the liberation of small molecules (e.g., CO2 and NH3) under N2 atmosphere. The effects of thermal degradation on the performance of the obtained membranes were investigated. The TESPS-BTESE- and TESPU-BTESE-based membranes calcined at 250 ºC and 200 ºC exhibited good CO2/N2 permselectivities of 20.2 and 14.4, respectively, and low CO2 permeances of 7.7 × 10-8 and 7.9 × 10-8 mol m-2s-1Pa-1, respectively. When the membranes were further calcined at elevated temperatures of 350 ºC and 300 ºC, respectively, to promote the thermal degradation of the organic units, the CO2 permeances increased to 1.3 × 10-7 and 1.2 × 10-6 mol m-2s-1Pa-1, although the CO2/N2 permselectivities decreased to 19.5 and 8.4, respectively. These data indicate possible tuning of the CO2 separation performance of PSQ membranes by controlling the thermal degradation of the organic units.

Wheat a widely grown cereal crop, which accounts for about 30 percent of the world grain output and affects the half of the land cultivated with wheat. Drought has a robust impact which affect 40 percent of wheat production and crop response, and other factor like plant growth, productivity, pigments contents, leaf senescence, fertility of spike, water relations and also photosynthetic activities. Low yield can be attributed to the planting time and varietal selection. To meet the need for food grains, high yielding genotypes resistant to diverse biotic and abiotic stress must be established and well performed genotypes are selected using multiplicative trails. So, the main objective of the study is to find the most stable, high yielding and adaptive genotype through genotype-environment interaction. The data were interpreted using AMMI (Additive Main Effect and Multiplicative Interaction) and GGE biplots. The experiment was conducted on twenty wheat genotypes in alpha lattice design on irrigated and heat drought environment. AMMI model showed that the grain yield is significantly affected by environment and 83.03%, 8.24%, 8.73% is attributed to environment, genotype and environment*genotype interaction. According to AMMI model, NL 1384 is the high yielding genotype in irrigated environment and NL 1179 under heat drought. NL 1346 is the winning elite line of drought environment and NL 1384 is the winning elite line for this environment as per GGE biplot analysis. Mean versus stability showed that NL 1384 is the highest mean yielding genotype and ranking genotype revealed NL 1420 is the ideal genotype.
Enhancing Generative Adversarial Networks with Attention Mechanisms for Image Synthesis
Authors: Neyigapula Bheema Shanker
Published: August 2023

Generative Adversarial Networks (GANs) have significantly advanced image syn- thesis, but challenges persist in generating realistic and coherent images. This research paper introduces a novel Attention-Enhanced Generative Adversarial Network (A-GAN) that integrates attention mechanisms into the GAN frame- work to address these limitations. The attention module guides the generator’s focus on relevant image regions, leading to improved image quality, fine-detail capture, and global coherence preservation. Extensive experiments on diverse datasets demonstrate the superiority of A-GAN over traditional GANs, show- casing enhanced image realism, diversity, and spatial consistency. The proposed A-GAN model is applicable across various image synthesis tasks, such as image- to-image translation, style transfer, and image inpainting. The incorporation of attention mechanisms offers promising avenues for advancing computer vision and artificial intelligence applications.
Long read sequencing characterises a novel structural variant opaque to short reads, with likely functional impact in a case of unexplained severe fatigue

Published: August 2023

Despite the recent advances in genomic analysis, causative variants cannot be found for a sizeable proportion of patients with suspected genetic disorders. Many of these disorders involve genes in difficult-to-align genomic regions which are recalcitrant to short read approaches. Structural variants in these regions can be particularly hard to detect or define with short reads, yet may account for a significant number of cases. Long read sequencing can overcome these difficulties and is providing new hope for diagnosis and patient care. Here, we present a case of unusually complex, severe fatigue where a potentially relevant structural variant was indicated but could not be resolved by short-read sequencing. We use nanopore sequencing to identify and fully characterise a large inversion in a highly homologous region spanning the AKR1C gene locus, along with serum steroid analysis to investigate the functional consequences. The DNA inversion appears to increase the expression of AKR1C2 while limiting AKR1C1 activity, resulting in a relative increase of inhibitory neurosteroids and impaired progesterone metabolism. This study provides an example of where long read sequencing may supplement the use of more traditional sequencing methods in clinical care to increase diagnostic yield for rare disease, and highlights some of the challenges that arise in sequencing complex regions containing tandem arrays of genes. It also proposes a novel gene associated with a specific disease aetiology that may be an underlying cause of unexplained severe fatigue.

Kilonovae are a rare class of astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects 1–4 . Over the first few days, the kilonova evolution is dominated by a large number of radioactive isotopes contributing to the heating rate2, 5 . On timescales of weeks to months, its behavior is predicted to differ depending on the ejecta composition and merger remnant6–9 . However, late-time observations of known kilonovae are either missing or limited10, 11 . Here we report observations of a luminous red transient with a quasi-thermal spectrum, following an unusual gamma-ray burst of long duration. We classify this thermal emission as a kilonova and track its evolution up to two months after the burst. At these late times, the recession of the photospheric radius and the rapidly-decaying bolometric luminosity (Lbol ∝ t −2.7±0.4) support the recombination of lanthanide-rich ejecta as they cool.

Along with developing high-speed craft technology, the planing hull is growing with modifications for better performance. One such technology is stepped hull, both single and double. Planing hull with steps allows the boat to run at a relatively low drag-lift ratio with lower frictional resistance due to reduced wetted area. In this study, the hull was modified with variations in the position of the double steps, which aimed to determine the effect of the first and second step positions on the total resistance, dynamic trim, and dynamic sinkage generated by computational fluid dynamics (CFD). Based on the analysis results, variations in the position of the stepped can change the hull performance. Shortening the distance between the two steps and moving both rearwards toward the transom can lower the total resistance. The dynamic trim and dynamic sinkage decreased as the position of the two steps was shifted further forward. An equation created in a non-dimensional form relates the positions of two steps to the desired results of total resistance, dynamic trim, and dynamic sinkage, namely: {(x1-x2)/L + (x1x2)/(LB)} × Fr∇, where x1 is distance the first step from transom, x2 is the distance of the second step, L is the length of the boat, B is the beam of the boat, and Fr∇ is the volume Froude number.
Nonequilibrium phases of ultracold bosons with cavity-induced dynamic gauge fields
Authors: Kosior Arkadiusz , Ritsch Helmut , Mivehvar Farokh
Published: August 2023

Gauge fields are a central concept in fundamental theories of physics, and responsible for mediating long-range interactions between elementary particles. Recently, it has been proposed that dynamical gauge fields can be naturally engineered by photons in composite, neutral quantum gas-cavity systems using suitable atom-photon interactions. Here we comprehensively investigate nonequilibrium dynamical phases appearing in a two-leg bosonic lattice model with leg-dependent, dynamical complex tunnelings mediated by cavity-assisted two-photon Raman processes. The system constitutes a minimal dynamical flux-lattice model. We study fixed points of the equations of motion and their stability, the resultant dynamical phase diagram, and the corresponding phase transitions and bifurcations. Notably, the phase diagram features a plethora of nonequilibrium dynamical phases including limit-cycle and chaotic phases. In the end, we relate regular periodic dynamics (i.e., limit-cycle phases) of the system to time crystals.

Published: August 2023

Starobinsky inflation is an attractive, fundamental model to explain the Planck measurements, and its higher-order extension may allow us to probe quantum gravity effects. We show that future CMB data combined with the 21cm intensity map from SKA will meaningfully probe such an extended Starobinsky model. A combined analysis will provide a precise measurement and intriguing insight into inflationary dynamics, even accounting for correlations with astrophysical parameters.

El cuerpo humano en el “monismo estructurista dinamicista” de Laín Entralgo: aportes para un diálogo con el transhumanismo tecnocientífico
Authors: García Echeverri Jonny Alexander , Giraldo Zuluaga Conrado
Published: August 2023

La presente reflexión tiene por objetivo central aportar, desde la teoría científico-filosófica sobre el cuerpo humano construida por Pedro Laín Entralgo, una propuesta antropológica que posibilite el diálogo con el transhumanismo tecnocientífico. A nivel metodológico, el texto se ha estructurado en dos momentos. En el primero, se hace una revisión de la situación (sitius) del cuerpo de cara al transhumanismo info, para luego, en un segundo momento, aportar (locus), desde la obra lainiana, una concepción antropológica integral. Se espera que, al pensar la materia desde un dinamismo estructural que hace de la realidad corpórea una unidad psico-orgánica capaz de decir “yo” (persona), se pueda establecer un cuestionamiento profundo a la concepción antropológica propuesta por el transhumanismo info, para la cual, el cuerpo orgánico es materia inútil de la que es necesario liberarse para superar los límites de la biología.
The effect of absolute return strategies on risk-factor diversification and portfolio performance
Authors: Cloutier Richard , C. Mikkelson Alan
Published: August 2023

Absolute return strategies attempt to generate positive returns that are uncorrelated with equity or bond markets and can be used to increase diversification and performance within multi-asset class portfolios. The current paper compared diversification and portfolio performance between traditional multi-asset class portfolios and multi-asset class portfolios with the addition of absolute return strategies. Using closing prices from January 1, 2000 – June 30, 2018, this paper back-tested two multi-asset class portfolios, one composed of equities, fixed income securities, and real return strategies, and the other portfolio composed of the same asset classes but with the addition of absolute return strategies. In particular, the absolute return strategies that this paper added were equity market neutral strategies, managed futures, and global macro strategies. Results indicated that the use of absolute return strategies improved diversification by increasing the portfolio’s effective number of bets (ENB) and enhanced risk adjusted returns as measured by improved Sharpe ratios, Treynor ratios, Jensen’s Alphas, and Sortino ratios. In addition, results showed that the benefits of adding absolute return strategies accrued throughout a full market cycle, which included declines and advances. These results support previous research on the individual absolute return strategies and demonstrate that the portfolio performance and investor wealth can be improved with the addition of these absolute return strategies to multi-asset class portfolios.

Authors: Zhou Rui , Zhou Ping , Yu Yi-Feng , Lin Qin , Wu San-Gang
Published: August 2023

Aims:

To investigate the short-term objective response and treatment toxicity of anlotinib as a combination treatment in patients with recurrent or metastatic nasopharyngeal carcinoma (RM-NPC).

Methods:

Patients with RM-NPC who received anlotinib as a combination treatment
between March 2021 and July 2022 were retrospectively analyzed.The efficacy and safety of anlotinib as a combination treatment were analyzed.

Results:

A total of 17 patients with RM-NPC were included in this study. Of these patients, 2 (11.8%) had local recurrence, 4 (23.5%) had cervical lymph node recurrence, and 11 (64.9%) had distant failure. The most common metastatic site was the liver (47.1%), followed by the lung (23.5%) and bone (23.5%). Anlotinib was given as first-line treatment in 3 patients (17.6%), second lines treatment in 7 patients (41.2%), and third to six-lines treatment in 7 patients (41.2%). All patients received anlotinib combined with chemotherapy and/or immunotherapy. One patient achieved a complete response (5.9%), 7 patients had a partial response (41.2%), 5 patients had stable disease (29.4%), and 4 patients had progressive disease (23.5%). The overall disease control rate and the overall response rate were 76.5% and 47.1%, respectively. The median progression-free survival was 8.1 months, and the median overall survival was not reached. The incidence of grade 3 adverse events was 30%. No unexpected side effects or treatment-related death were observed.

Conclusions:

Anlotinib, as a combination treatment, has a promising antitumor activity and a manageable safety profile in patients with RM-NPC. Our results add to the growing evidence that supports the benefits of combining antiangiogenic drugs in RM-NPC. Randomized controlled clinical trials investigating the evaluation of anlotinib are warranted.
Biobehavioral Interactions between Endocannabinoid and Hypothalamicpituitary-
adrenal Systems in Psychosis: A Systematic Review
Authors: Colizzi Marco , Bortoletto Riccardo , Antolini Giulia , Bhattacharyya Sagnik , Balestrieri Matteo , Solmi Marco
Published: August 2023

Background:

The diathesis-stress paradigm and the cannabinoid-hypothesis have been proposed
as possible pathophysiological models of schizophrenia. However, they have historically been
studied independently of each other.

Objective:

This PRISMA 2020-compliant systematic review aimed at reappraising the interplay between
the hypothalamic-pituitary-adrenal (HPA) axis and the endocannabinoid (eCB) system in psychosis-
spectrum disorder risk and outcome.

Methods:

All pathophysiological and outcome clinical studies, concomitantly evaluating the two systems
in psychosis-spectrum disorder risk and different stages of illness, were gathered from electronic
databases (Pubmed, Web of Science, and Scopus), and discussed.

Results:

41 eligible outputs were extracted, focusing on at least a biological measure (9 HPA-related
studies: 4 eCB-interventional, 1 HPA-interventional, 1 both HPA-interventional and non-interventional, 3
non-interventional; 2 eCB-related studies: non-interventional), environmental measures only (29 studies:
1 eCB- interventional, 28 non-interventional), and genetic measures (1 study: non-interventional). Independent
contributions of aberrancies in the two systems to the physiopathology and outcome of psychosis
were confirmed. Also, concomitant alterations in the two systems, either genetically defined
(e.g., CNR1 genetic variation), biologically determined (e.g., dysfunctional HPA axis or endocannabinoid
signaling), or behaviorally imputed (e.g., cannabis use, stress exposure, and response), were
consistently reported in psychosis. Further, a complex biobehavioral perturbation was revealed not only
within each system (e.g., cannabis use affecting the eCB tone, stress exposure affecting the HPA axis),
but also across the two systems (e.g., THC affecting the HPA axis, childhood trauma affecting the
endocannabinoid signaling).

Conclusion:

There is a need to concomitantly study the two systems’ mechanistic contribution to psychosis
in order to establish more refined biological relevance.

Cancer is one of the leading causes of mortality and morbidity worldwide, affecting
millions of people physically and financially every year. Over time, many anticancer treatments
have been proposed and studied, including synthetic compound consumption, surgical procedures,
or grueling chemotherapy. Although these treatments have improved the daily life quality of patients
and increased their survival rate and life expectancy, they have also shown significant drawbacks,
including staggering costs, multiple side effects, and difficulty in compliance and adherence
to treatment. Therefore, natural compounds have been considered a possible key to overcoming
these problems in recent years, and thorough research has been done to assess their effectiveness.
In these studies, scientists have discovered a meaningful interaction between several
natural materials and signal transducer and activator of transcription 3 molecules. STAT3 is a
transcriptional protein that is vital for cell growth and survival. Mechanistic studies have established
that activated STAT3 can increase cancer cell proliferation and invasion while reducing
anticancer immunity. Thus, inhibiting STAT3 signaling by natural compounds has become one
of the favorite research topics and an attractive target for developing novel cancer treatments. In
the present article, we intend to comprehensively review the latest knowledge about the effects
of various organic compounds on inhibiting the STAT3 signaling pathway to cure different
cancer diseases.
Chronic Stress as a Risk Factor for Type 2 Diabetes: Endocrine, Metabolic,
and Immune Implications
Authors: Lisco Giuseppe , Giagulli Vito Angelo , De Pergola Giovanni , Guastamacchia Edoardo , Jirillo Emilio , Vitale Elsa , Triggiani Vincenzo
Published: August 2023

Background:

Background: Chronic stress is a condition of pressure on the brain and whole body, which
in the long term may lead to a frank disease status, even including type 2 diabetes (T2D). Stress
activates the hypothalamus-pituitary-adrenal axis with release of glucocorticoids (GCs) and catecholamines,
as well as activation of the inflammatory pathway of the immune system, which alters glucose
and lipid metabolism, ultimately leading to beta-cell destruction, insulin resistance and T2D
onset. Alteration of the glucose and lipid metabolism accounts for insulin resistance and T2D outcome.
Furthermore, stress-related subversion of the intestinal microbiota leads to an imbalance of the
gut-brain-immune axis, as evidenced by the stress-related depression often associated with T2D.

:

A condition of generalized inflammation and subversion of the intestinal microbiota represents another
facet of stress-induced disease. In fact, chronic stress acts on the gut-brain axis with multiorgan
consequences, as evidenced by the association between depression and T2D.

:

Oxidative stress with the production of reactive oxygen species and cytokine-mediated inflammation
represents the main hallmarks of chronic stress. ROS production and pro-inflammatory cytokines
represent the main hallmarks of stress-related disorders, and therefore, the use of natural antioxidant
and anti-inflammatory substances (nutraceuticals) may offer an alternative therapeutic approach to
combat stress-related T2D. Single or combined administration of nutraceuticals would be very beneficial
in targeting the neuro-endocrine-immune axis, thus, regulating major pathways involved in
T2D onset. However, more clinical trials are needed to establish the effectiveness of nutraceutical
treatment, dosage, time of administration and the most favorable combinations of compounds. Therefore,
in view of their antioxidant and anti-inflammatory properties, the use of natural products or
nutraceuticals for the treatment of stress-related diseases, even including T2D, will be discussed.
Several evidences suggest that chronic stress represents one of the main factors responsible for the
outcome of T2D.
A dispersão das catástrofes. O ilimitado e a estrução do mundo
Authors: Rosa Jorge Leandro
Published: August 2023

In this text, we propose to examine the ways in which Nancy’s thought of catastrophe, indebted to Heidegger’s questioning of ontology and its history, embarks on a reading of the contemporary world marked by the passage of the “with” (Mitdasein) from the existential plane to the plainly categorial one. Thus, the ontological constitution of the existing slides into pure juxtaposition, as this appears in his analysis of the “proliferation of ends” and their incessant transformation into means.We also dedicate our attention to the ruin, saturation and rupture of the “construction” model. It is in the infinitization of each and every action, through the unpredictable technical architecture in the base of its design, that the catastrophic penetrates the world with its constitutive multiplicity and the state of “suspension” that defines it. The life of waste in its dispersion is exemplary in this context: the catastrophe thus unfolds in lapses thrown into the environment and the psyche of the subjects, something that can be seen as the introjection of the temporality of struction.The anomie that today shelters the catastrophes that intertwine before our eyes, apparently “scandalous” in a paradigm of action, takes place in a «present that never fulfills itself as presence» (Nancy) and that finds itself in the impossibility of expressing the meaning of the world. The disorder of struction, which characterizes what some inappropriately call the Anthropocene, does not happen as a reversal or a destruction of an order, but rather as a disconnection of the imperative character of the order. From this question, a discussion opens on the meaning of the community that is on the verge of catastrophe.
The human-made aspect of disasters. A philosophical perspective from Japan
Authors: Jannel Romaric , Droz Laÿna , Fuke Takahiro
Published: August 2023

What is a disaster? This paper explores the different hermeneutic levels that need to be taken into consideration when approaching this question through the case of Japan. Instead of a view of disasters as spatiotemporal events, we approach disasters from the perspective of the milieu. First, based on the Japanese «dictionaries of disasters», the Japanese vocabulary of disaster is described. Second, this paper reviews briefly the Japanese interdisciplinary disaster-management tradition. To highlight the human-made aspect of disasters, the idea of fūdo風土 is introduced. This concept allows us to see disasters as a phenomenon of the milieu, which emerges from the co-constitutive relations between individuals, communities, and the local environment. The final part debates the narratives by some national and international political actors that link «Japanese identity and culture» to disaster management and sometimes include nationalist claims rooted in the essentialization of the «Japanese exception». Given the cruciality of sociocultural and political representations of disasters tied to identity politics, and the increasing frequency and intensity of disasters, a long-term, local people-focused and culturally sensitive perspective on disasters might be better adapted to the climate change era.

Premarital Cohabitation as a Model of Matrimonial Behavior of Young People
Authors: Kobleva Z. Kh.
Published: August 2023

The relevance of the research topic is caused by the emergence of serious scientific interest in the study of value orientations in the system of traditional premarital behavior, characterized by the presence of destructive phenomena and the formation of a new model of premarital strategy of young people, which have a serious impact on value preferences and attitudes in the system of choosing forms of family and marriage relations.

It was found that the traditional system of premarital behavior has undergone a significant transformation associated with increased interest on the part of young people in cohabitation during the premarital period, reflecting the obvious processes of individualization of values and significant changes in the system of behavioral models in the youth environment.

The purpose of this article is due to the identification of the main social mechanisms that have a significant impact on the formation of premarital cohabitation among young people.

Objectives: to consider the main values in the modern youth environment; to analyze the motives and identify the reasons for the formation of premarital cohabitation in the youth environment in the context of modern transformational processes.

Methodology. In the course of work on the study, methods of systemic, structural and functional analysis were used, methods of comparison, observation, questioning and interviewing were used in the process of studying value orientations in the system of premarital behavior of young people.

Results. The sociological research conducted within the framework of the problem posed allowed analyzing the features of the value preferences of young people in choosing the main marriage strategies in modern conditions; to determine the degree of influence of social factors on the functioning of the system of premarital behavior, which has undergone significant changes in modern conditions.

Conclusions. The transformational processes affecting the institution of the family caused by the difficult socioeconomic conditions of life in Russian society, which had a significant impact on the formation of new value orientations and attitudes among young people, had a significant impact on the state of the system of traditional premarital behavior.
Employment of Graduates of Secondary Vocational and Higher Education Institutions of the Kursk Region in Conditions of Disproportion between the Educational Segment and the Labor Market
Authors: Abramov A. P. , Tatarenkova D. Yu. , Chuichenko V. D.
Published: August 2023

Relevance. In modern conditions, when significant social and social changes are taking place, the problem of employment of graduates of institutions of secondary vocational and higher education is becoming important and needs fundamental changes in the field of employment. Due to the imbalance in the process of training specialists at all levels of education with the real needs of the labor market, there is periodically an oversaturation or shortage of certain professions. Consequently, there is a disproportion between supply and demand in the field of educational services, on the one hand, and the employment market, on the other. 

The purpose is to identify the causes and consequences of the imbalance of the educational sphere and the labor market and employment.

Objectives: to characterize theoretical approaches to the analysis of the socio-economic nature of the labor market; to determine the value attitudes of young people in the professional and labor sphere; to identify the problems of employment of young professionals in the labor market of the Kursk region.

Methodology. The study is based on concepts and theories that reveal the socio-cultural and socio-economic nature of the Russian labor market and employment. Methods of synthesis, comparison and analogy were applied, which made it possible, on the basis of specific empirical material, to determine the main problems of employment of graduates of institutions of secondary vocational and higher education in the Kursk region.

Results. Educational institutions have a low orientation towards the training of qualified specialists. Communication employer (economic entity) - graduate (university) is in a state of imbalance and ultimately does not solve the problem of youth entering the labor market.

Conclusions. The main difficulties in finding a decent job are the rather high requirements of the employer to the applicant and the lack of work experience in the chosen profession. The most significant factors in employment are wages, proximity of work to home and flexible employment schedule. It is not always good (excellent) academic performance at a university (SSU) that becomes the determining factor on the part of the employer for choosing a potential candidate for a particular vacancy.

Relevance. Recently, the activation of investment activity has become the main method of ensuring the economic security of the region. The current economic situation has opened up new development opportunities for the regions, which without a qualitative change in the regional investment climate, activation and stimulation of investment processes for the development of the economic sectors of the region will not be realized and will not provide the necessary level of economic security. A special role in the system of coordinated and targeted measures to attract investment is assigned to the development and implementation of non-financial instruments, which is confirmed by the laws on investment activity and on public-private partnership adopted in the Kursk region.

The purpose of the study is evaluate the instruments for stimulating investment activity enshrined in the legislation of the Kursk region.

Objectives: on the example of the Kursk region, to consider and systematize the instruments enshrined in the legislation to stimulate investment activity and attract investment; conduct a study of the dynamics of investments in fixed assets for 2016-2020; determine the need to use new tools to attract investment in the region's economy.

Methodology. Methods of system analysis, theoretical and methodological research of literary sources, monographic and comparative methods were used.

Results. The most promising instruments for stimulating investment activity have been identified for use in the region in order to increase investment attractiveness in the context of ensuring the economic security of the region. 

Conclusions. To stimulate investment activity in the region, it is necessary to search for new tools to attract investment, among which are public-private partnerships, the implementation of elements of the Regional Investment Standard, agreements on the protection and promotion of investments. The use of these tools to stimulate investment activity will increase the investment attractiveness and, as a result, the level of economic security of the region.

The effect of the target material and the size of the irradiated volume on the efficiency of ozone synthesis in air under the action of a pulsed electron beam is investigated. Graphite and lead targets were used. The highest concentration of ozone was observed in a chamber without a target, and the highest specific ozone yield without consideration of electron reflection (230 g(kWh)–1) was observed in a chamber with a lead target at a minimum air gap (3 cm). The results are explained by the processes of multiple reflection of electrons from elements with a high atomic number at small air gaps compared to the size of the target.

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there are better ways to regulate voltage. It also asserts that these ways must be sought before blindly procuring a static Var compensator or seeking battery storage. We simulated with a 70-MW photovoltaic plant as an addition to the grid. Without voltage regulation, voltage violations in Spring were found to be particularly significant. However, the proposed reactive power compensation removed all voltage violations smartly. Furthermore, the study results demonstrated that the operator-induced curtailment effectively reduced the necessary amount of reactive power compensation, leading to a smaller size of SVC, as it occurred specifically at certain overvoltage points. This paper argues that the economic and spatial efficiency of reactive power compensation devices is key to increasing photovoltaic penetration. It argues that one-sided bearing of the cost of reactive compensation devices is inefficient.

The Use of a Decision Support System (MyFood) to Assess Dietary Intake Among Free-Living Older Adults in Norway: Evaluation Study
Authors: Severinsen Frida , Andersen Lene Frost , Paulsen Mari Mohn
Published: August 2023

Background

The proportion of older adults in the world is constantly increasing, and malnutrition is a common challenge among the older adults aged ≥65 years. This poses a need for better tools to prevent, assess, and treat malnutrition among older adults. MyFood is a decision support system developed with the intention to prevent and treat malnutrition.

Objective

This study aimed to evaluate the ability of the MyFood app to estimate the intake of energy, protein, fluids, and food and beverage items among free-living older adults aged ≥65 years, primarily at an individual level and secondarily at a group level. In addition, the aim was to measure the experiences of free-living older adults using the app.

Methods

Participants were instructed to record their dietary intake in the MyFood app for 4 consecutive days. In addition, each participant completed two 24-hour recalls, which were used as a reference method to evaluate the dietary assessment function in the MyFood app. Differences in the estimations of energy, protein, fluid, and food groups were analyzed at both the individual and group levels, by comparing the recorded intake in MyFood with the 2 corresponding recalls and by comparing the mean of all 4 recording days with the mean of the 2 recalls, respectively. A short, study-specific questionnaire was used to measure the participants’ experiences with the app.

Results

This study included 35 free-living older adults residing in Norway. Approximately half of the participants had ≥80% agreement between MyFood and the 24-hour recalls for energy intake on both days. For protein and fluids, approximately 60% of the participants had ≥80% agreement on the first day of comparison. Dinner was the meal with the lowest agreement between the methods, at both the individual and group levels. MyFood tended to underestimate the intake of energy, protein, fluid, and food items at both the individual and group levels. The food groups that achieved the greatest agreement between the 2 methods were eggs, yogurt, self-composed dinner, and hot beverages. All participants found the app easy to use, and 74% (26/35) of the participants reported that the app was easy to navigate.

Conclusions

The results showed that the MyFood app tended to underestimate the participants’ dietary intake compared with the 24-hour recalls at both the individual and group levels. The app’s ability to estimate intake within food groups was greater for eggs, yogurt, and self-composed dinner than for spreads, mixed meals, vegetables, and snacks. The app was well accepted among the study participants and may be a useful tool among free-living older adults, given that the users are provided follow-up and support in how to record their dietary intake.
