Background: Stroke is a medical condition that leads to major disability and mortality worldwide. Some evidence suggests that weather and seasonal variations could have an impact on stroke incidence and outcome. However, the current evidence is inconclusive. Therefore, this study examines the seasonal variations and meteorological influences on stroke incidence and outcome in the largest city in Saudi Arabia.Methods: From February 2016 to July 2019, we retrospectively reviewed data from all patients with acute ischemic (AIS) or hemorrhagic stroke (HS) admitted to the stroke unit in a tertiary academic center in Saudi Arabia. The corresponding daily meteorological data were obtained for the same period. We considered the months from November to March as the cold season and April to October as the hot season.Results: The final cohort included 1,271 stroke patients; 60.89% (n = 774) cases occurred in the hot season, while 39.1% (n = 497) in the cold season. Males accounted for 69.6% (n = 884) of the cases. The proportion of ischemic stroke was 83.2% [hot season 83.9% (n = 649) vs. cold season 82.3% (n = 409)]. We found no statistically significant difference between seasons (hot or cold) in stroke incidence, severity [National Institutes of Health Stroke Scale (NIHSS)], hospital course (pneumonia, thromboembolism, intensive care stay, or length of stay), or outcome [modified Rankin scale (mRS) on discharge and death].Conclusions: In Riyadh, Saudi Arabia, our study found no impact of weather or seasonal variations on stroke incidence, hospital course, or outcomes. However, our findings warrant further research in different country regions.

Background: Previous studies had shown that poor quality of early parental attachment is a risk factor for suicide, but few have focus on the mechanism between suicidal ideation and parental attachment. The aim of this study was to explore how parental attachment, anhedonia, and peer attachment were associated with suicidal ideation in adolescents.Method: Participants were enrolled in middle schools, in Hefei, Anhui, China. All participants completed socio-demographic characteristic and standard assessments on parental attachment, peer attachment, anhedonia, and suicidal ideation by paper surveys. The effect of parental attachment on suicidal ideation mediated by anhedonia and peer attachment was analyzed by a structural equation model (SEM) using SPSS AMOS 23.0.Results: The SEM analysis revealed that the standard total effect of parental attachment on suicidal ideation was −0.137 (Z=−27.00, 95% confidence interval [CI; −0.147, −0.127], p&lt;0.001), with a direct effect of parental attachment on suicidal ideation of −0.107 (Z=−21.40, 95% CI [−0.117, −0.098], p&lt;0.001), while the indirect effects were−0.002 (Z=−3.33, 95% CI [−0.003, −0.002], p&lt;0.001) in the pathway of parental attachment-anhedonia-peer attachment-suicidal ideation, −0.019 (Z=−19.00, 95%CI [−0.022, −0.017], p&lt;0.001) in the pathway of parental attachment-anhedonia-suicidal ideation, and−0.008 (Z=−7.00, 95% CI [−0.010, −0.007], p&lt;0.001) in the pathway of parental attachment-peer attachment-suicidal ideation.Conclusion: The study suggested that parental attachment could directly influence suicidal ideation and indirectly influence suicidal ideation via anhedonia and peer attachment. The results emphasized the importance of attachment in infancy and verified the feasibility of intervention on anhedonia and peer attachment to prevent suicidal ideation.
Bioprocess Optimization for the Production of Arthrospira (Spirulina) platensis Biomass Enriched in the Enzyme Alkaline Phosphatase
Authors: Markou Giorgos 
Published: October 2021

The enzyme alkaline phosphatase (ALP) is gaining interest because it exerts bioactive properties and may be a potentially important therapeutic agent for many disorders and diseases. Microalgae are considered an important novel source for the production of diverse bio-compounds and are gaining momentum as functional foods/feeds supplements. So far, studies for the production of ALP are limited to mammalian and partly to some heterotrophic microbial sources after its extraction and/or purification. Methods: Arthrospira was cultivated under P-limitation bioprocess and the effect of the P-limitation degree on the ALP enrichment was studied. The aim of this work was to optimize the cultivation of the edible and generally-recognized-as-safe (GRAS) cyanobacterium Arthrospira platensis for the production of single-cell (SC) biomass enriched in ALP as a potential novel functional diet supplement. Results: The results revealed that the relationship between intracellular-P and single-cell alkaline phosphatase (SC-ALP) activity was inverse; SC-ALP activity was the highest (around 50 U g−1) when intracellular-P was the lowest possible (around 1.7 mg-P g−1) and decreased gradually as P availability increased reaching around 0.5 U g−1 in the control cultures. Under the strongest P-limited conditions, a more than 100-fold increase in SC-ALP activity was obtained; however, protein content of A. platensis decreased significantly (around 22–23% from 58%). Under a moderate P-limitation degree (at intracellular-P of 3.6 mg-P g−1), there was a relatively high SC-ALP activity (>28 U g−1) while simultaneously, a relative high protein content (46%) was attained, which reflects the possibility to produce A. platensis enriched in ALP retaining though its nutritional value as a protein rich biomass source. The paper presents also results on how several parameters of the ALP activity assay, such as pH, temperature etc., and post-harvest treatment (hydrothermal treatment and biomass drying), influence the SC-ALP activity.
Three-Port Series-Resonant DC/DC Converter for Automotive Charging Applications
Authors: Schäfer Jannik , Kolar Johann Walter 
Published: October 2021

In the energy distribution grid of electric vehicles (EVs), multiple different voltage potentials need to be interconnected, to allow arbitrary power flow between the various energy sources and the different electrical loads. However, between the different potentials, galvanic isolation is absolutely necessary, either due to safety reasons and/or due to different grounding schemes. This paper presents an isolated three-port DC/DC converter topology, which, in combination with an upstream PFC rectifier, can be used as combined EV charger for interconnecting the single-phase AC mains, the high-voltage (HV) battery and the low-voltage (LV) bus in EVs. The proposed topology comprises two synergetically controlled and magnetically coupled converter parts, namely, a series-resonant converter between the PFC-sided DC-link capacitor and the HV battery, as well as a phase-shifted full-bridge circuit equivalent in the LV port, and is mainly characterized by simplicity in terms of control and circuit complexity. For this converter, a simple soft switching modulation scheme is proposed and comprehensively analyzed, in consideration of all parasitic components of a real converter implementation. Based on this analysis, the design of a 3.6 kW, 500 V/500 V/15 V prototype is discussed, striving for the highest possible power density and as low as possible manufacturing costs, by using PCB-integrated windings for all magnetic components. The hardware demonstrator achieves a measured full-load efficiency in charge mode of 96.5% for nominal operating conditions and a power density of 16.4 kWL−1.

SEJARAH PASTORAL KEUSKUPAN SURABAYA: 1850-1942
Authors: Laksito Petrus Canisius Edi 
Published: October 2021

This article deals with some elements of pastoral works and care of souls in the Diocese of Surabaya, in the East Java, Indonesia, especially in the mission era of 1850-1942. This period, which ends with the defeat of the colonial power of the Dutch by the Japanese occupation forces, is of great importance, because it laid the foundation of the community life of this Diocese for the next periods. Being still in the period of mission, pastoral works of caring the souls of those days were characterized by the atmosphere of mission works. While as a term “mission” was still a “keyword” of this period, it is hoped that a good understanding about this period could be a good introduction for the future study of the history of pastoral works in the Diocese of Surabaya.

The structural and layout solution of rods of Y-shaped and Ψ-shaped outlines in trusses with a cross lattice or trusses with a cross lattice and half-posts (half-suspensions) is presented, the technical novelty of which is confirmed by the results of patent examination. The versatility of this truss solution is as effective as it is for load tops, load bottoms, or load tops and bottoms of the same grid. The degree of unification of a typical truss of rolled sections has been increased due to the use of design sections in the upper belt adopted for the lower belt. At the same time, the resources of the bearing capacity differ between them by no more than one and a half percent, which ensures the necessary and sufficient equal strength of both belts for their more rational unification. A comparative analysis of the main results of the solution of the variant and optimal design of truss structures as applied to gratings with double systems of half-braces and gratings with single systems of braces is carried out. The prospect of using a new technical solution in the composition of bearing and communication systems of various buildings and structures has been revealed.

Вследствие малоизученности геокриологических условий ряда скважин месторождений Сибири, авторы провели исследования, направленные на разработку методов стабилизации теплообменных процессов и сохранения природной среды. Была предложена эффективная методика сохранения баланса в системе скважина - пласт, что будет крайне актуально на месторождениях сибири, арктического и субарктического климатического пояса. Изучаемое нами Сузунское месторождение характерно тем, что оно состоит в области многолетнемерзлых пород (ММП) и подвержено их непрерывному воздействию. Оно принадлежит Западно-Енисейской зоне, которая, в свою очередь, входит в Западно-Сибирско-Хатангскую глубинку, характеризуемую высокой отрицательной температурой (Гинсбург, 1971). Общегодовая температура мерзлотного рельефа и пород меняется в огромной доле местности от-1°С вплоть до -5°С. Преимущественно холодные температуры характерны промерзшим осадочным породам равнин и террас, в плоскости которых сформирован низкий мохово-лишайниковый слой, который почти никак не противодействует выдуванию осадков.Помимо этого, в данной статье была проведена работа по моделированию теплообменных процессов между скважинами и зоной расположения многолетнемерзлых пород.
