AbstractThe galloping rise in global population in recent years and the accompanying increase in food and energy demands has created land use crisis between food and energy production, and eventual loss of agricultural lands to the more lucrative photovoltaics (PV) energy production. This experiment was carried out to investigate the effect of organic photovoltaics (OPV) and red-foil (RF) transmittance on growth, yield, photosynthesis and SPAD value of spinach under greenhouse and field conditions. Three OPV levels (P0: control; P1: transmittance peak of 0.11 in blue light (BL) and 0.64 in red light (RL); P2: transmittance peak of 0.09 in BL and 0.11 in RL) and two spinach genotypes (bufflehead, eland) were combined in a 3 × 2 factorial arrangement in a completely randomized design with 4 replications in the greenhouse, while two RF levels (RF0: control; RF1: transmittance peak of 0.01 in BL and 0.89 in RL) and two spinach genotypes were combined in a 2 × 2 factorial in randomized complete block design with four replications in the field. Data were collected on growth, yield, photosynthesis and chlorophyll content. Analysis of variance (ANOVA) showed significant reduction in shoot weight and total biomass of spinach grown under very low light intensities as a function of the transmittance properties of the OPV cell used (P2). P1 competed comparably (p > 0.05) with control in most growth and yield traits measured. In addition, shoot to root distribution was higher in P1 than control. RF reduced shoot and total biomass production of spinach in the field due to its inability to transmit other spectra of light. OPV-RF transmittance did not affect plant height (PH), leaf number (LN), and SPAD value but leaf area (LA) was highest in P2. Photochemical energy conversion was higher in P1, P2 and RF1 in contrast to control due to lower levels of non-photochemical energy losses through the Y(NO) and Y(NPQ) pathways. Photo-irradiance curves showed that plants grown under reduced light (P2) did not efficiently manage excess light when exposed to high light intensities. Bufflehead genotype showed superior growth and yield traits than eland across OPV and RF levels. It is therefore recommended that OPV cells with transmittance properties greater than or equal to 11% in BL and 64% in RL be used in APV systems for improved photochemical and land use efficiency.
Is temperature change a key driver of the regional differences in electricity consumption of the economic sectors in Spain (2000–2016)?

AbstractClimate change has caused significant changes in temperature with different consequences depending on the geographical location of the regions, affecting among other aspects, electricity consumption (EC). Spain being a country that encompasses so many different temperature zones, this work analyses EC per capita among the Autonomous Communities (AC) of Spain through a spatial-temporal decomposition analysis during the 2000–2016 period. The regional differences are explained by four decomposition factors: intensity, temperature, structural and per capita income. The temporal decomposition results show that temperature changes in Spain between 2000 and 2016 have substantially affected the per capita EC. Likewise, it has been noted that in the 2000–2008 period, the temperature effect mainly acted as an inhibitor compared to the 2008–2016 period, in which an increase in the days of extreme temperature acted as a driver. The spatial decomposition reveals that the structural and energy intensity effects contribute to the AC moving away from average figures, while the temperature and income effects contributes to reducing the differences depending on the location of the AC. The results enable to determine the importance of establishing public policy measures aimed at improving energy efficiency.
The Role of Self-Esteem, Depressive Symptoms, Extraversion, Neuroticism and FOMO in Problematic Social Media Use: Exploring User Profiles
Authors: Packer Jennifer , Flack Mal 
Published: June 2023

AbstractProblematic social media use (PSMU) is known to be associated with self-esteem, depressive
symptomology, extraversion, neuroticism and the fear of missing out (FOMO).
However, few studies have sought to understand how these psychological factors
may converge and differentially relate to PSMU severity. Thus, the current study
examined how these factors may present as different ‘user profiles’. A total of
574 participants completed an online survey, and hierarchical cluster analysis
and K-means clustering techniques were used to form profiles. A five-cluster
solution was identified. The clusters differed in PSMU scores and in order of
PSMU severity were identified as FOMO, Emotionally Vulnerable, Low-risk, Low
Extraversion and Protective profiles. These findings indicate a more nuanced
understanding of PSMU severity may be gained by considering how specific
psychological correlates converge as opposed to considering them as unique
predictors of PSMU. Future research may benefit from conceptualising PSMU from
a combined risk lens that prioritises the relationship between PSMU correlates.

Published: June 2023

AbstractCOVID-19 posed threats for health and well-being directly, but it also revealed and exacerbated social–ecological inequalities, worsening hunger and poverty for millions. For those focused on transforming complex and problematic system dynamics, the question was whether such devastation could create a formative moment in which transformative change could become possible. Our study examines the experiences of change agents in six African countries engaged in efforts to create or support transformative change processes. To better understand the relationship between crisis, agency, and transformation, we explored how they navigated their changed conditions and the responses to COVID-19. We document three impacts: economic impacts, hunger, and gender-based violence and we examine how they (re)shaped the opportunity contexts for change. Finally, we identify four kinds of uncertainties that emerged as a result of policy responses, including uncertainty about the: (1) robustness of preparing a system to sustain a transformative trajectory, (2) sequencing and scaling of changes within and across systems, (3) hesitancy and exhaustion effects, and (4) long-term effects of surveillance, and we describe the associated change agent strategies. We suggest these uncertainties represent new theoretical ground for future transformations research.
A new miniaturized microextraction HS-LPME-OIP procedure for ammonium determination based on Nessler's method

Published: June 2023

AbstractA recently proposed combination of headspace liquid-phase microextraction with an optical immersion probe (HS-LPME-OIP) was adapted for the spectrophotometric determination of ammonium. The developed method is based on the conversion of ammonium ions to ammonia in a 0.15 M sodium hydroxide solution, followed by the absorption of ammonia by 200 µL of Nessler's reagent solution preliminary diluted with distilled water (1:16.7). The extracting phase, in which OIP was immersed, was placed into vial fixed in the headspace above the sample solution in a hermetically sealed vessel. The analytical signal was monitored for 30 min at 400 nm. The duration of the analysis can be flexibly adjusted and, if necessary, reduced to 5 min. The level of permissible concentrations of some interfering substances, including calcium, magnesium, iron and some organic compounds, was significantly reduced. The LOD was equal to 0.20 mg L−1, and the linear calibration range was from 0.70 to 15 mg L−1. The RSD ranged from 2.5 to 5.2%. The developed method was successfully applied to the analysis of natural waters, fertilizers and CRM samples.

AbstractThe first accelerator mass spectrometry (AMS) laboratory in the Czech Republic has been established and put into routine operation in February 2022. Here we briefly describe the facilities available, namely a 300 kV multi-isotope low-energy AMS system (MILEA) capable of determination 10Be, 14C, 26Al, 41Ca, 129I, isotopes of U, especially 236U, Pu and other actinoids, and accessories for 14C measurements, which include a gas interface system, a preparative gas chromatography system for compound-specific radiocarbon dating analysis, and an isotope-ratio mass spectrometer. The first results achieved for separation and measurement of the above radionuclides (except for 41Ca) are also reported, with the main focus on 14C measurements. A specimen breakdown of 729 graphitised samples analysed for 14C so far is presented, as well as a proof of measurement stability of the MILEA system obtained by analysis of radiocarbon standards and analytical blanks. For the other radionuclides, well proven or novel procedures for sample preparation and measurement are presented.

Published: June 2023

ZusammenfassungDas neue Mietspiegelgesetz erlaubt die Berücksichtigung von sogenannten außergesetzlichen Merkmalen wie Mietdauer und Vermietertyp bei der Erstellung von Mietspiegeln. Diese außergesetzlichen Merkmale dürfen in zukünftigen Mietspiegeln bei deren Erstellung und Modellwahl Einfluss finden, nicht aber im konkreten Mietspiegelmodell. Diese gesetzliche Vorgabe lässt viel Spielraum, der in diesem Beitrag aus statistischer Sicht beleuchtet wird. Anhand von konkreten Daten werden die Konsequenzen quantifiziert und aufgezeigt.

AbstractMyelodysplastic syndromes (MDS) are incurable diseases characterized by dysplastic hematopoietic cells, cytopenias in the blood and an inherent tendency for transformation to secondary acute myeloid leukemia (AML). Since most therapies fail to prevent rapid clonal evolution and disease resistance, new and non-invasive predictive markers are needed to monitor patients and adapt the therapeutic strategy. By using ISET, a very sensitive approach to isolate cells larger than mature leukocytes from peripheral blood samples, we looked for cellular markers in 99 patients (158 samples) with MDS and 66 healthy individuals (76 samples) used as controls. We found a total of 680 Giant Cells, defined as cells having a size of 40 microns or larger in 46 MDS patients (80 samples) and 28 Giant Cells in 11 healthy individuals (11 samples). In order to understand if we had enriched from peripheral blood atypical cells of the megakaryocyte line, we studied the Giant Cells using immunolabeling with megakaryocytes and tumor-specific markers. We report that the Giant Cells we found in the peripheral blood of MDS patients primarily express tumor markers. Our results show that Polyploid Giant Cancer Cells (PGCC), similar to those described in solid tumors, are found in the peripheral blood of patients with MDS and suggest the working hypothesis that they could play a role in hematological malignancies.

AbstractNiemann-Pick type C1 (NPC1) disease is a lysosomal lipid storage disorder due to mutations in the NPC1 gene resulting in the accumulation of cholesterol within the endosomal/lysosomal compartments. The prominent feature of the disorder is the progressive Purkinje cell degeneration leading to ataxia.In a mouse model of NPC1 disease, we have previously demonstrated that impaired Sonic hedgehog signaling causes defective proliferation of granule cells (GCs) and abnormal cerebellar morphogenesis. Studies conducted on cortical and hippocampal neurons indicate a functional interaction between Sonic hedgehog and brain-derived neurotrophic factor (BDNF) expression, leading us to hypothesize that BDNF signaling may be altered in Npc1 mutant mice, contributing to the onset of cerebellar alterations present in NPC1 disease before the appearance of signs of ataxia.We characterized the expression/localization patterns of the BDNF and its receptor, tropomyosin-related kinase B (TrkB), in the early postnatal and young adult cerebellum of the Npc1nmf164 mutant mouse strain.In Npc1nmf164 mice, our results show (i) a reduced expression of cerebellar BDNF and pTrkB in the first 2 weeks postpartum, phases in which most GCs complete the proliferative/migrative program and begin differentiation; (ii) an altered subcellular localization of the pTrkB receptor in GCs, both in vivo and in vitro; (iii) reduced chemotactic response to BDNF in GCs cultured in vitro, associated with impaired internalization of the activated TrkB receptor; (iv) an overall increase in dendritic branching in mature GCs, resulting in impaired differentiation of the cerebellar glomeruli, the major synaptic complex between GCs and mossy fibers.

SamenvattingInleidingProblematisch alcoholgebruik neemt toe onder ouderen (55+). Veel interventies om alcoholgebruik te voorkomen of te verminderen, zijn gericht op volwassenen. Het is onduidelijk of deze interventies ook werken voor ouderen. Het doel van deze review was om te begrijpen hoe het komt (welke elementen), in welke context en waarom interventies (welke mechanismen) succesvol zijn in het voorkomen of verminderen van (problematisch) alcoholgebruik bij ouderen.MethodeEen systematische review van artikelen gepubliceerd tussen 2000 en 2022 werd uitgevoerd met behulp van PubMed, PsycINFO, Web of Science en CINAHL. Een realistische evaluatiebenadering werd gebruikt voor data-analyse.ResultatenWe vonden 61 onderzoeken over interventies gericht op het voorkomen of verminderen van (problematisch) alcoholgebruik, waarbij de meeste interventies niet specifiek ontwikkeld waren voor ouderen. Er werden drie belangrijke werkzame interventie-elementen gevonden: 1) informatie verstrekken over de gevolgen van alcoholgebruik; 2) persoonlijke feedback over drinkgedrag; en 3) in contact staan met anderen en hiermee communiceren over (alcohol)problemen. De eerste twee elementen werden gebruikt in de interventies die voor ouderen ontwikkeld waren.ConclusieMeer onderzoek is nodig naar alcoholinterventies voor ouderen en naar de manier waarop ouderen geholpen kunnen worden om contact te maken met mensen die hun keuze om alcoholgebruik te verminderen kunnen ondersteunen.
Existence results on Lagrange multiplier approach for gradient flows and application to optimization
Authors: Onuma Kenya , Sato Shun 
Published: June 2023

AbstractThis paper deals with the geometric numerical integration of gradient flow and its application to optimization. Gradient flows often appear as model equations of various physical phenomena, and their dissipation laws are essential. Therefore, dissipative numerical methods, which are numerical methods replicating the dissipation law, have been studied in the literature. Recently, Cheng, Liu, and Shen proposed a novel dissipative method, the Lagrange multiplier approach, for gradient flows, which is computationally cheaper than existing dissipative methods. Although their efficacy is numerically confirmed in existing studies, the existence results of the Lagrange multiplier approach are not known in the literature. In this paper, we establish some existence results. We prove the existence of the solution under a relatively mild assumption. In addition, by restricting ourselves to a special case, we show some existence and uniqueness results with concrete bounds. As gradient flows also appear in optimization, we further apply the latter results to optimization problems.

AbstractThe reliability of electrical assets is greatly influenced by the quality of their insulations. Key power installations such as power cables are manufactured with polymer-based materials as part of their insulation system. However, accelerated ageing of equipment insulations due to manifestation of defect(s), and partial discharges (PDs) can offset the operation of these systems or even lead to breakdowns. In this study, a non-deterministic model to simulate the phenomenon of repetitive discharges in a spherical air-filled cavity within a practical power cable has been investigated. In addition, the work contributes to the understanding of PD behaviour and field distribution under different ageing conditions considering changes in cavity surface conductivity. First, a section of the practical XLPE cable containing the cavity is developed in 2D using COMSOL software, and a finite element analysis (FEA) of the electric field distribution within the cable insulation is performed. The magnitude of the cavity local field, that is enough to ignite a PD, is investigated. Alongside the COMSOL model, the activity of sustained internal PD is simulated in MATLAB by introducing a random sample generating factor and adjusting the model’s parameters to obtain something close to the practical results. Furthermore, the impact of continuous PD in the power cable under different cavity dimensions and surface conductivity is likewise investigated, and a phase resolved PD (PRPD) pattern is established. The result shows that the magnitude and number of PDs per cycle increase as the cavity size and its surface conductivity increase. Finally, when the cavity surface conductivity rises, the amplitude of the electric field generated by the surface charge distribution and the number of PDs per cycle approach their maximum values.
The Effect of Intraoperative Hypotension on Postoperative Renal Function

Published: June 2023

Abstract
Purpose of Review
This review summarizes the most recent literature on the association between intraoperative hypotension (IOH) and the occurrence of postoperative acute kidney injury (AKI). It provides recommendations for the management of intraoperative blood pressure to reduce the incidence of postoperative AKI. Fluid management strategies, administration of vasopressor medications, and other methods for reducing the incidence of AKI are also briefly discussed.

Recent Findings
Recent retrospective studies have demonstrated a solid association of IOH with postoperative AKI. IOH is associated not only with AKI but also with myocardial infarction, stroke, and death. Strict BP management to avoid a mean blood pressure less than 65mmHg is now recommended to reduce the incidence of postoperative AKI and other adverse outcomes.

Summary
IOH is robustly associated with AKI, and intraoperative mean BP should be maintained above 65 mmHg at all times. The etiology of postoperative AKI is however multifactorial, and factors other than BP therefore also need to be considered to prevent it.

AbstractObjectiveImmersive virtual reality (VR) and augmented reality (AR) have the potential to improve the treatment and diagnosis of individuals experiencing psychosis. Although commonly used in creative industries, emerging evidence reveals that VR is a valuable tool to potentially improve clinical outcomes, including medication adherence, motivation, and rehabilitation. However, the efficacy and future directions of this novel intervention require further study. The aim of this review is to search for evidence of efficacy in enhancing existing psychosis treatment and diagnosis with AR/VR.Methods2069 studies involving AR/VR as a diagnostic and treatment option were reviewed via PRISMA guidelines in five databases: PubMed, PsychInfo, Embase, and CINAHL.ResultsOf the initial 2069 articles, 23 original articles were eligible for inclusion. One study applied VR to the diagnosis of schizophrenia. Most studies demonstrated that the addition of VR therapies and rehabilitation methods to treatment-as-usual (medication, psychotherapy, social skills training) was more effective than traditional methods alone in treating psychosis disorders. Studies also support the feasibility, safety, and acceptability of VR to patients. No articles using AR as a diagnostic or treatment option were found.ConclusionsVR is efficacious in diagnosing and treating individuals experiencing psychosis and is a valuable augmentation of evidence-based treatments.
