The Physical Properties of Massive Green Valley Galaxies as a Function of Environments at 0.5 < z < 2.5 in 3D-HST/Candels Fields
Authors: Chang Wenjun , Fang Guanwen , Gu Yizhou , Lin Zesen , Lu Shiying , Kong Xu
Published: August 2022

To investigate the effects of environment in the quenching phase, we study the empirical relations for green valley (GV) galaxies between overdensity and other physical properties (i.e., effective radius r

e
, Sérsic indices n, and specific star formation rate (sSFR)). Based on five 3D-HST/CANDELS fields, we construct a large sample of 2126 massive (M
⋆ > 1010
M
☉) GV galaxies at 0.5 < z < 2.5 and split it into the higher overdensity quarter and the lower overdensity quarter. The results shows that GV galaxies in denser environments have higher n values and lower sSFR at 0.5 < z < 1, while there is no discernible distinction at 1 < z < 2.5. No significant enlarging or shrinking is found for GV galaxies in different environments within the same redshift bin. This suggests that a dense environment would promote the growth of bulges and suppress star formation activity of GV galaxies at 0.5 < z < 1.5 but would not affect the galaxy size. We also study the dependence of the fraction of three populations (blue cloud, GV, and red sequence) on both environments and M
⋆. At a given M
⋆, blue cloud fraction goes down with increasing environment density, while red sequence fraction is opposite. For the most massive GV galaxies, a sharp drop appears in the denser environment. Coupled with the mass dependence of three fractions in different redshift bins, our result implies that stellar mass and environments jointly promote the quenching process. Such a dual effect is also confirmed by recalculating the new effective GV fraction as the number of GV galaxies over the number of nonquiescent galaxies.

Published: August 2022

Observations and simulations have demonstrated that star formation in galaxies must be actively suppressed to prevent the formation of overly massive galaxies. Galactic outflows driven by stellar feedback or supermassive black hole accretion are often invoked to regulate the amount of cold molecular gas available for future star formation but may not be the only relevant quenching processes in all galaxies. We present the discovery of vast molecular tidal features extending up to 64 kpc outside of a massive z = 0.646 post-starburst galaxy that recently concluded its primary star-forming episode. The tidal tails contain (1.2 ± 0.1) × 1010
M
⊙ of molecular gas, 47% ± 5% of the total cold gas reservoir of the system. Both the scale and magnitude of the molecular tidal features are unprecedented compared to all known nearby or high-redshift merging systems. We infer that the cold gas was stripped from the host galaxies during the merger, which is most likely responsible for triggering the initial burst phase and the subsequent suppression of star formation. While only a single example, this result shows that galaxy mergers can regulate the cold gas contents in distant galaxies by directly removing a large fraction of the molecular gas fuel, and plausibly suppress star formation directly, a qualitatively different physical mechanism than feedback-driven outflows.

Published: August 2022

A new fossil species of Dryinidae (Hymenoptera, Chrysidoidea) from upper Eocene Rovno amber (Ukraine) is described: Bocchus rexsp. nov. It is compared with two other species of Bocchus known from European amber: B. primaevus Martins & Melo from Baltic amber and B. schmalhauseni Perkovsky, Olmi, Vasilenko, Capradossi & Guglielmino from Rovno amber. A new key to the Cretaceous and Paleogene species of Bocchus is presented. The Dryininae are the most common representatives in all the amber dryinid faunas since the mid-Cretaceous. The Rovno amber fauna is an exception; possible explanations for the abundance of Bocchus species within this amber are presented.
Robust stabilization for uncertain saturated systems with multiple time delays
Authors: Chen Yuzhen , Liu Haoxin , Dong Rui
Published: August 2022

This paper is concerned with the robust stabilization problem for uncertain saturated linear systems with multiple discrete delays. First of all, a new distributed-delay-dependent polytopic approach is proposed, and a new type of Lyapunov-Krasovskii functional is constructed. Then, by further incorporating some integral inequalities, both stabilization and robust stabilization conditions are proposed in terms of linear matrix inequalities under which the closed-loop systems are asymptotically stable for admissible initial conditions. Finally, a simulation example is given to illustrate the feasibility and advantages of the obtained results.
On smoothing of data using Sobolev polynomials
Authors: Castillo Rolly Czar Joseph , Mendoza Renier
Published: August 2022

Data smoothing is a method that involves finding a sequence of values that exhibits the trend of a given set of data. This technique has useful applications in dealing with time series data with underlying fluctuations or seasonality and is commonly carried out by solving a minimization problem with a discrete solution that takes into account data fidelity and smoothness. In this paper, we propose a method to obtain the smooth approximation of data by solving a minimization problem in a function space. The existence of the unique minimizer is shown. Using polynomial basis functions, the problem is projected to a finite dimension. Unlike the standard discrete approach, the complexity of our method does not depend on the number of data points. Since the calculated smooth data is represented by a polynomial, additional information about the behavior of the data, such as rate of change, extreme values, concavity, etc., can be drawn. Furthermore, interpolation and extrapolation are straightforward. We demonstrate our proposed method in obtaining smooth mortality rates for the Philippines, analyzing the underlying trend in COVID-19 datasets, and handling incomplete and high-frequency data.
An inverse volatility problem in a degenerate parabolic equation in a bounded domain
Authors: Yimamu Yilihamujiang , Deng Zui-Cha , Yang Liu
Published: August 2022

In this paper, an inverse problem of determining the space-dependent volatility from the observed market prices of options with different strikes is studied. Being different from other inverse volatility problem with classical parabolic equations, we apply the linearization method and introduce some variable substitutions to convert the original problem into an inverse source problem in a degenerate parabolic equation in a bounded area, from which an unknown volatility can be recovered and deficiencies caused by artificial truncation can be solved. Based on the optimal control framework, the problem is transformed into an optimization problem and the existence of the minimizer is established. After the necessary conditions are deduced, the uniqueness and stability of the minimizer are proved. Then, the Landweber iterative method is used to obtain a stable numerical solution of the inverse problem and some numerical experiments are also performed. The numerical results show that the algorithm which we proposed is robust and the unknown coefficient is recovered quite well.
„Jede Gefährdung wird zur Gnade“
Authors: Larcati Arturo
Published: August 2022

Der Aufsatz untersucht drei frühe Texte von Stefan Zweig – den kurzen lyrischen Epos Brief eines deutschen Malers aus Italien (1908) sowie die Novellen Die Wunder des Lebens (1904) und Der Zwang (1920) – als Beispiele für dessen Reflexion über den Künstler, der sich in einer schöpferischen Krise befindet und diese dann überwindet. In der Novelle Der Zwang steht zusammen mit der Krise der schöpferischen Kraft auch die Autonomie des Künstlers und die Legitimation seiner ganzen Existenz auf dem Spiel. Im Zuge seiner Auseinandersetzung mit dem Krisenmotiv entwickelt Stefan Zweig in den ersten beiden Texten eine Poetik des schaffenden Subjekts, in der sehr moderne Elemente zu erkennen sind. Im dritten Text verschränkt sich der Anspruch auf die ästhetische Entfaltung des Subjekts mit der Problematik der individuellen Freiheit im politischen Sinne. Die Dialektik von Krise und Krisenüberwindung prägt auch Zweigs Texte der zwanziger und dreißiger Jahre – wie zum Beispiel seinen Essay über Tolstoi in Drei Dichter ihres Lebens und die Sternstunde über Georg Friedrich Händel. Mit der Betonung des Spiels des Subjekts mit den eigenen Kräften und von dessen Disfunktionalität zur Gesellschaft entwickelt Zweig Ansätze, mit denen er sich an die transgressive Moderne annähert.

The Effect of Granite Filler Grain Size on its Physical and Chemical Properties with Regard to Use in Cement Composites
Authors: Musil Luboš , Chylík Roman , Vodicka Jan
Published: August 2022

The article deals with the use of granite filer as a concrete admixture. It examines the filter in detail not only as a whole (one component in concrete) but separates it into fractions. Since it is a filter produced during cutting, grinding and polishing of granite elements, it is granite slurry. For these reasons, the simplest method of separation - sedimentation in a flowing liquid - was applied to separate the individual fractions. After drying, the individual fractions were examined for their suitability for use in concrete. The most important physical and chemical parameters - bulk density, specific surface area, grain shape and size, chemical composition - were determined. Based on the measured values and in relation to previous in-house investigations, granite filer can be considered as a suitable admixture for cement composites.
K-Value Determination Options for Active Admixtures
Authors: Hubáček Adam , Hela Rudolf , Hubertová Michala , Sperling Petr
Published: August 2022

Concrete admixtures have been successfully used in cementitious composites (especially in concrete) for many years. Recently, however, their importance and usefulness has been increasing, especially with regard to the reduction of the clinker factor in concrete production. In the application of active admixtures in concrete, as a partial replacement of cement, k-value concepts are used in the design of concrete formulation and the calculation of the water coefficient. However, it is essentially a matter of determining the amount of total countable binder, i.e. the cement and part of the active admixture used to calculate the water coefficient. However, this concept does not address the activity of the admixture and the determination of the equivalent replacement of the cement by an admixture with a given hydraulic activity. The k-value concepts are poorly defined in the Czech standards. At present, the k-value only describes the effect of the addition of an active admixture on the value of the hydraulic coefficient, but does not take into account the dependence between the activity of the admixture and the replacement potential of a given cement type.

The ZnO replicas were clearly observed, the band structure and density of states of phase of crystal ZnO computed using Ab Initio methods, confirmed that pure ZnO is a direct band gap semiconductor for B3 phase, whose phase B3 is of ZnS type Blende.
Comparison between One-Dimensional and Three-Dimensional Optical Modelling of Ordered Black Silicon Nanostructures Using Effective Medium Approach
Authors: Chai Jasman Yi Hao , Wong Basil T. , Juodkazis Saulius
Published: August 2022

The aim of this study is to determine whether the effective medium approach (EMA) is suitable to model black silicon structures. The present study focuses on comparing EMA paired with 1D FDTD simulations to full 3D FDTD simulations. Comparison was done for ordered cylindrical and hemispherical b-Si nanostructures. From the simulation results, the 1D simulation seems to underestimate the transmittance and overestimate the reflectance for these structures. This was attributed to the failure of the EMA to capture scattering and diffraction effects that were present in the nanostructures. The absorptance spectrum was comparable for both 1D and 3D simulations, hence it was concluded that the simplification may be suitable for simplifying problems where calculating the absorption of light is desired.

Authors: Tipka Martin , Kostka Jan , Vaskova Jitka
Published: August 2022

Ultra-high performance concrete is a cementitious composite material with very high compressive and tensile strength, abrasion resistance, low permeability, and high durability. Currently it is used for special applications to a limited extent, especially for bridge structures. In Czech Republic UHPC is used in several bridges and footbridges. This paper deals with possibilities of ultra-high performance concrete use in buildings and geotechnical structures. In the Czech Republic, there is currently no standard document dedicated to the design of UHPC elements and structures. The most detailed document for UHPC design is the methodology of the Klokner Institute issued in 2015. For more detailed information it is necessary to choose foreign documents. A suitable standard can be two French National Annexes to Eurocode 2. Principles and differences of these documents are described in the first part of this paper. The French National Annex is then used for the design of two precast elements made of UHPC - a precast elements for hall roofing and retaining wall. The optimization of geometry and reinforcement of the cross-section of both elements is carried out. The behaviour of these elements is verified using non-linear numerical analysis. Finally, the proposed elements are compared with similar types of elements made of ordinary concrete.

Authors: Saeidi Sajjad , Asadi Parvin , Hassanzadeh Farshid , Aliomrani Mehdi , Khodarahmi Ghadam Ali
Published: August 2022

Background and purpose:

One of the most noteworthy methods to slow down multiple sclerosis (MS) progress is a decrease of lymphocyte cells via S1P1 receptor modulating. Here, a series of S1P1 receptor modulators were designed and investigated for their ability to decrease lymphocytes in a rat model.

Experimental approach:

Molecular docking was performed to compare the binding mode of desired compounds 5a-f with fingolimod to the active site of the S1P1 receptor, theoretically. To prepare desired compounds, 5a-f, cyanuric chloride was reacted with different amines, a-f, which then converted to 4a-f compounds through reaction with N-boc-Tyr-OMe ester. Finally, deprotection of the carboxyl and amino groups was carried out to obtain 5a-f as final products. Lymphocyte counting in the rat model was carried out using flow cytometry to evaluate the efficacy of the suggested compounds.

Findings / Results:

All compounds exhibited lower binding energy than fingolimod. Compound 5e with ΔG= -8.10 kcal/mol was the best compound. The structure of the compounds was confirmed spectroscopically. The in vivo study proved that compounds 5b and 5a decreased the lymphocytes level at 0.3 and 3 mg/kg, respectively.

Conclusion and implications:

The desired compounds were well fitted in the receptor active site following molecular docking studies. The results of lymphocyte count revealed that compounds 5a and 5b with propyl and ethyl substitutes showed the maximum activity in vivo. Finally, the results of the present project can be used for forthcoming investigations towards the design and synthesis of novel potential agents for MS treatment.
Extracted yam bean (Pachyrhizus erosus (L.) Urb.) fiber counteracts adiposity, insulin resistance, and inflammation while modulating gut microbiota composition in mice fed with a high-fat diet
Authors: Santoso Putra , Maliza Rita , Rahayu Resti , Astrina Yunita , Syukri Firman , Maharani Septalian
Published: August 2022

Background and purpose

Yam bean (Pachyrhizus erosus) is a potent medicinal plant exerting therapeutical effects against diseases. However, investigations on the health benefits of its fiber remain limited. This study aimed to investigate the potential of yam bean fiber (YBF) against a high-fat diet (HFD)-induced metabolic diseases, inflammation, and gut dysbiosis.

Experimental approach:

Adult male mice were assigned to four groups (8 each), namely a normal diet-fed group (ND), HFD-fed group, and HFD supplemented with YBF groups (HFD + YBF) at a dose of 2.5% and 10%, respectively. Treatments were implemented for ten weeks. Thereafter, indicators of metabolic diseases, oxidative stress, inflammation, and gut microbiota composition were determined.

Findings / Results:

A dosage of 10% YBF significantly inhibited excessive body weight gain (2.3 times lower than HFD group) and white adipose tissue (WAT) mass (2.2 times lower than HFD group) while sustaining brown adipose tissue mass. YBF prevented malondialdehyde elevation, catalase activity reduction, and expression of the interleukin-6 increment (2.7 times lower than the HFD group) within the WAT. Furthermore, YBF sustained normoglycaemia, glucose tolerance, and insulin sensitivity while precluding hyperinsulinemia. YBF modulated the gut microbiota community by increasing health-promoting microbiota including Lactobacillus reuteri, L. johnsonii, and inhibiting a pathogenic Mucispirillum sp. YBF prevented histopathology and inflammation of the colon.

Conclusion and implications:

YBF at the dose of 10% is proved to be useful in the prevention of diet-induced metabolic diseases, microbiota dysbiosis, and inflammation. Hence, YBF is recommended as a potential natural-based remedy to diminish the detrimental effects of high-fat foods.

Published: August 2022

Background and purpose

Histone deacetylation is one of the essential cellular pathways in the growth and spread of cancer, so the design of histone deacetylase (HDAC) inhibitors as anticancer agents is of great importance in pharmaceutical chemistry. Here, a series of indole acylhydrazone derivatives of 4-pyridone have been introduced as potential histone deacetylase inhibitors.

Experimental approach:

Seven indole-acylhydrazone-pyridinone derivatives were synthesized via simple, straightforward chemical procedures. The molecular docking studies were accomplished on HDAC2 compared to panobinostat. The cytotoxicity of all derivatives was studied on MCF-7 and MDA-MB-231 breast cancer cell lines by MTT assay.

Findings / Results:

Molecular docking studies supported excellent fitting to the HADC2 active site with binding energies in the range of -10 Kcal/mol for all derivatives. All compounds were tested for their cytotoxicity against MCF-7 and MDA-MB-231 cell lines; derivatives A, B, F, and G were the best candidates. The half-maximal inhibitory concentration (IC50) values on MCF-7 were below 25 mg/mL and much lower than those obtained on the MDA-MB-231 cell line.

Conclusion and implications:

The derivatives showed selectivity toward the MCF-7 cell line, probably due to the higher HDAC expression in the MCF-7 cell line. In this regard, debenzylated derivatives F and G showed slightly better cytotoxicity, which should be more studied in the future. Derivatives A, B, F, and G were promising for future enzymatic studies.

Published: August 2022

Background and purpose

Ferula gummosa (F. gummosa), a potent medicinal herb, has been shown to possess anticancer activities in vitro. The present examination evaluated the cytotoxic and apoptogenic impacts of F. gummosa gum on the U87 glioblastoma cells.

Experimental approach:

MTT assay to determine the cell viability, flow cytometry by annexin V/FITC-PI to apoptosis evaluation, reactive oxygen species (ROS) assay, and quantitative RT-PCR were performed.

Findings / Results:

The results revealed that F. gummosa inhibited the growth of U87 cells in a concentration- and time-dependent manner with IC50 values of 115, 82, and 52 μg/mL obtained for 24, 48, and 72 h post-treatment, respectively. It was also identified that ROS levels significantly decreased following 4, 12, and 24 h after treatment. The outcomes of flow cytometry analysis suggested that F. gummosa induced a sub-G1 peak which translated to apoptosis in a concentration-dependent manner. Further examination revealed that F. gummosa upregulated Bax/Bcl-2 ratio and p53 genes at mRNA levels.

Conclusion and implications:

Collectively, these findings indicate that sub-G1 apoptosis and its related genes may participate in the cytotoxicity of F. gummosa gum in U87 cells.

Authors: Upadhyay Ranjani , Saluja Satish , Modi Manoj , Soni Arun
Published: August 2022

Necrotising pneumonia (NP) is an uncommon condition in children when compared with the adult age group and is even more reported in the new-borns. The first published data on NP in children date back to 1994, but still there is a paucity of data when it comes to the new-borns. Pathologically, it is characterised by inflammation of the pulmonary tissue with consolidation and peripheral necrosis, thereby leading to local destruction of lung tissue and development of multiple small lung cavities. Bronchopleural fistula (BPF) is a rare complication of NP seen in new-born. In this case report, we discuss a case of new-born with severe NP complicated by BPF.

Published: August 2022

Objective To describe the frequency, type, and severity of reported medication incidents that occurred at a long-term care facility (LTCF) despite electronic medication administration record and barcode-assisted medication administration (eMAR-BCMA) use. The study also contains
analysis for the contribution of staff workarounds to reported medication administration errors (MAEs) using an established typology for BCMA workarounds, characterize if the eMAR-BCMA technology contributed to MAEs, and explore characteristics influencing incident severity. Design
Retrospective incident report review. Setting A 239-bed LTCF in Alberta, Canada, that implemented eMAR-BCMA in 2013. Participants 270 paper-based, medication incident reports submitted voluntarily between June 2015 and October 2017. Interventions
None. Results Most of the 264 resident-specific medication incidents occurred during the administration (71.9%, 190/264) or dispensing (28.4%, 75/264) phases, and 2.3% (6/264) resulted in temporary harm. Medication omission (43.7%, 83/190) and incorrect time (22.6%,
43/190) were the most common type of MAE. Workarounds occurred in 41.1% (78/190) of MAEs, most commonly documenting administration before the medication was administered (44.9%, 35/78). Of the non-workaround MAEs, 52.7% (59/112) were notassociated with the eMAR-BCMA technology, while 26.8%
(30/112) involved system design shortcomings, most notably lack of a requirement to scan each medication pouch during administration. MAEs involving workarounds were less likely to reach the resident (74.4 vs 88.8%; relative risk = 0.84, 95% CI 0.72-0.97). Conclusion Administration
and dispensing errors were the most reported medication incidents. eMAR-BCMA workarounds, and design shortcomings were involved in a large proportion of reported MAEs. Attention to optimal eMAR-BCMA use and design are required to facilitate medication safety in LTCFs.
A Dentist’s Perspective on the Need for Interdisciplinary Collaboration to Reduce Medication-Related Osteonecrosis of the Jaw
Authors: Griffin Alec , Brain Patrick , Hancock Colby , Jeyapalina Sujee
Published: August 2022

Antiresorptive medications, including bisphosphonates and RANK-L inhibitors, are commonly used to treat various skeletal pathologies. One devastating complication associated with these drugs is medication-related osteonecrosis of the jaw (MRONJ). Patients who develop MRONJ suffer immensely from oral lesions that may persist, even with treatment, until their death. The jawbone is known to remodel 5 to 10 times faster than skeletal bone. Dentists are at the forefront in managing the severe maxillofacial repercussions of MRONJ. Because MRONJ risk is relatively low (reportedly 0.7% to 6.7%) it is underappreciated by many clinical specialties. The minimization of MRONJ is further compounded because it may take months or years to develop. To date, dental treatment protocols are based more on expert opinion than concrete scientific evidence. This iatrogenic, intractable illness is discouraging for both the patient and the treating dentist. To promote multidisciplinary understanding and cooperation, a single MRONJ case caused by intravenous pamidronate is presented, along with commentary from a dentist’s perspective. The intent is that these data will increase awareness of MRONJ’s stomatognathic consequences to the physician, who prescribed the causative agent, and the pharmacist, who dispensed it. Collaboration between the dentist, physician, and pharmacist has tremendous potential to improve treatment strategies and, ultimately, optimize patient care.

Published: August 2022

As passenger cars are progressively moving towards more electrification, Plug-in Hybrid Electric Vehicles (PHEVs) may play a greater role. Several questions arise regarding their performance in real-world conditions, their optimal configuration - in terms of battery capacity, fuel and powertrain used - and their pollutant emissions. In this context, two PHEVs complying with Euro 6d standards were evaluated on a chassis-dyno and on-road using the same road profile, complying with RDE requirements. The two vehicles differ only by their powertrain, one being diesel-fueled, and the other being gasoline-fueled. The vehicles were tested under various conditions, including charge depleting and charge sustaining modes (i.e., tests respectively starting with a fully charged battery and a discharged battery), with various fuel compositions including traditional fossil-based fuels, 100% renewable Hydrotreated Vegetable Oil (HVO) and 100% renewable gasoline, blended with 20% v/v ethanol (E20). The vehicle weight was also artificially varied on the chassis-dyno to assess the difference of performance between a PHEV and a Hybrid Electric Vehicle (HEV), having a lower-capacity battery. The set of measurements included fuel and electricity consumptions, CO2 and regulated pollutant emissions (NOx, CO, HC, PN23, PM) as well as non-regulated pollutant emissions such as PN10, CH4, NH3 and N2O. The results show that the two vehicles have regulated pollutant emissions levels well below the Euro 6d limits under all testing conditions, and unregulated pollutant emissions in the range of Euro 7 proposals. For the PHEVs and operating conditions tested, switching from a traditional fossil-based fuel to a 100% renewable fuel, for both gasoline and Diesel powertrains, does not have statistical significant impact on the pollutant emissions. Regarding fuel and powertrain aspects, it is observed that switching from a gasoline- to a Diesel-PHEV enables a reduction of CO2 emissions whilst also lowering pollutant emissions except for NH3 and N2O. However, on-road tests results show significantly higher fuel consumption than chassis-dyno tests, although being driven on the same test-cycle.

Treatment 1: planting seedlings in plots exposed to hydrogel. Treatment 2: planting seedlings and depositing mulch around them. Treatment 3: planting seedlings in plots exposed to hydrogel and mulch depositing around seedlings. Using hydrogel in planting seedlings, mulch deposition around seedlings, or the combination of both, increase the survival rate and favors greater diameter and height growth in G. guidonia seedlings, as well as enhances forest restoration through seedling planting in degraded sites located in regions subject to water shortage.

AIMS OF THE STUDY: Suicide is one of the leading causes of death in young people. Therefore, suicide prevention in this age group is a public health priority. There is increasing evidence of the efficacy of suicide prevention programmes, but robust empirical studies are still needed. More precisely, data are needed for school-aged children, brief interventions and distal outcomes such as psychological distress or suicidal thoughts. In addition, to our knowledge, no study has yet scientifically evaluated a brief universal suicide prevention programme in Switzerland. This study investigated the efficacy and acceptability of a brief universal suicide prevention programme for school-aged youths. Primary outcomes included knowledge on suicide, perceived suicide awareness and knowledge of help-seeking resources. Secondary outcomes included acceptability coping skills, suicide-related behaviours and psychological distress.
METHODS: This non-randomised cluster-controlled trial was conducted in Swiss schools. A 90-minute workshop for universal suicide prevention was delivered to the intervention group (n = 209), and the control group had no intervention (n = 96). Measures were assessed at baseline and after one month. Acceptability was assessed at follow-up in the intervention group only. Data were analysed using three-level mixed effect models with an interaction term between group and time.
RESULTS: There were interaction effects between group and time for most outcomes: perceived suicide awareness (p <0.010), knowledge of help-seeking resources (p <0.001), coping planning (p = 0.039), suicidal ideation (p = 0.019) and psychological distress (p = 0.012). There were no interaction effects on suicide-related knowledge (p = 0.312) and coping for social support (p >0.388). Participants found the workshop enjoyable, not upsetting, and worthwhile.
CONCLUSIONS: This study suggested that a brief suicide prevention programme could be beneficial and safe for school-aged youths. This brief programme may contribute to suicide prevention efforts.

OBJECTIVES: We present an adolescent with cardiogenic shock due to ventricular tachycardia 2 weeks after SARS-CoV-2 infection. Acute myocarditis or myocardial dysfunction is associated with SARS-CoV-2 infection, but diagnosis may be difficult, even including endomyocardial biopsy.
CASE REPORT: A 15-year-old  healthy adolescent was admitted to our hospital 2 weeks after SARS-CoV-2 infection with cardiogenic shock due to ventricular tachycardia. After cardioversion, antiarrhythmic treatment, ventilation, and inotropic support, the severely reduced myocardial function recovered completely within 2 weeks. Cardiac magnetic resonance imaging and cardiac catheterisation including right ventricular endomyocardial biopsy revealed an increased number of CD68+ macrophages in the myocardium, but nested (RT-) polymerase chain reaction (PCR) investigations revealed no viral or bacterial DNA/RNA.
DISCUSSION: SARS-CoV-2 infection may be associated with myocarditis leading to life-threatening arrhythmia and severe myocardial systolic and diastolic dysfunction, which may be short lasting and completely recover. Although former SARS-Cov-2 infection might suggest SARS-CoV-2-associated myocarditis, definite histological diagnosis including nested PCR investigations remains difficult.

The Covid-19 pandemic has had an adverse impact on religious destinations ever since its outbreak was reported from Wuhan, China in 2019. The aim of this paper is to diagnose the impact Covid-19 pandemic has had on tourism and religious destinations. Empirical evidence elucidates that the Covid-19 pandemic has wreaked havoc on tourism and religious destinations. For example, Christianity, social beliefs and values of individuals, pilgrims were threatened, and faith tested during the pandemic. As such, the aim of this paper is to diagnose the impact that was endured by the Catholic religious destinations in KwaZulu-Natal Province, South Africa. This is notwithstanding the fact that some religious destinations have not fully recovered even though they are operating. In this study, qualitative approach was employed, unstructured interviews conducted, and systematic sampling randomly done at the pilgrimage
destinations visited. Furthermore, NViVo 12 plus was used to transcribe the responses from the participants. The study elucidates on the sufferings endured by pilgrims who annually visited these religious destinations. The rituals such as that of the Catholic venerating the Virgin Mother Mary every month of October was halted. The discussions of the study focus on the elements of Christianity and social value that were compromised because of the Covid-19 pandemic. Religion and social value theory is reflected on in this discussion. The findings indicate a descriptive analysis of how Covid-19 impacted on the religious destinations of the study area. Lastly, the strategies for the religious and pilgrimage destinations post Covid-19 pandemic to survive are suggested and discussed in this chapter.

Stress is any situation in which universal demand arises in an individual to respond or to take action. Stress can affect a person's regular reality perception, problem-solving abilities, community spirit, interpersonal interactions, and more. Working women have a significant influence in the global growth of countries and must manage their careers while continuing to fulfil their conventional duties as wives, mothers, and earners. This indicates that duties are growing for working women and they are under a lot of stress.
PASSIVE CONTROL OF VORTEX-INDUCED MOTIONS ON DEEP-DRAFT SEMISUBMERSIBLE PLATFORMS

Published: August 2022

The deep-draft semisubmersible (DDSS) platform is well known due to its favourable vertical motion routine. However, DDSS platforms face a serious challenge in vortex-induced motion (VIM) due to the changing forces of the column. A computational fluid dynamic (CFD) simulation using AcuSolve is conducted to investigate the effect of a twisted-square column with different twisted angles, 0°, 22.5°, 45.0°, 67.5° and 90.0°, on the VIM responses and performance at current incidence angles of 0° and 45°.Platform models at a scale of 1:70 are studied to determine that the alteration of vortex shedding due the separation line at the twisted column expressively influences the mean and fluctuation of hydrodynamic forces and motion. In particular interest is the drag and lift coefficients, surge, sway amplitudes, as well as the yaw motion of the DDSS platform. The simulation was conducted at a velocity of 0.16 m/s.

A study on the distribution of benthic foraminiferal species in the surface sediments of coral reefs was carried out in Pulau Bidong in the southern South China Sea (SCS). Samples were collected at 12 sites around Pulau Bidong at water depths ranging from 5 m to 30 m. Live (rose bengal stained) and optimally preserved empty tests of benthic foraminifera were analysed based on their chamber and apertural characteristics observed under binocular microscope (Leica Zoom 2000). The results revealed that 32 genera of benthic foraminifera were found in the coral reefs sediments. Amphistegina was the most abundant genus with relative abundance of 68% and frequently recorded at depths of between 10-15 m and 25-30 m. Other common genera that were found were Calcarina, Elphidium, Heterolepa, Heterostegina, Quinqueloculina, Peneroplis and Triloculina. These genera showed depth distribution preference in the shallow water zone (5 m depth). The highest diversity index (2.3) and number of taxa (26 genera) were recorded at station W2, located at the western part of Pulau Bidong. The lowest diversity index (0.2) and number of taxa (seven genera) were recorded at station S3, located at the southern part of Pulau Bidong. The frequency distribution and diversity of benthic foraminifera in the study area were related to water depth.

Porcine respiratory coronavirus is an enzootic, viral, respiratory disease of pigs, which manifests with mild clinical signs, but it takes part in the etiopathogenesis of the porcine respiratory disease complex. The virus was first discovered in Belgium in 1984 as a deletion mutant of the transmissible gastroenteritis virus. The two viruses are strongly antigenically related which is why they cross-react in serological tests. In this study, we tested 276 serum samples from different categories of pigs using ELISA test, which allows differentiation between the porcine respiratory coronavirus infection and transmissible gastroenteritis. The seroconversion for coronavirus infection was determined in 80.4% of tested samples. Out of 222 positive samples, 219 samples (98.6%) were positive for porcine respiratory coronavirus antibodies, while 3 (1.01%) samples were positive for transmissible gastroenteritis virus antibodies. Depending on the production category, 97.7% of piglets, 83% of sows, and 35% of gilts tested positive for porcine respiratory coronavirus antibodies. In total, 2.3% of piglets tested positive for transmissible gastroenteritis virus antibodies. Taking into account the characteristics of the ELISA test, its sensitivity and specificity, this result can be considered a false positive, because of a cross-reaction between the porcine respiratory coronavirus antibodies and the transmissible gastroenteritis virus. Specific antibodies in other swine production categories against the transmissible gastroenteritis virus were not determined.
