The image of power in telegrams from the Urals to Petrograd in March 1917
Authors: Korolev N.S.
Published: January 2021

Based on the involvement of a diverse range of sources, this article examines the attitude of the Ural workers to the new government after the victory of the February revolution. Their analysis, and above all the telegrams from the Ural factories to Petrograd, led to the conclusion that the workers supported her immensely, and that they hoped for a rapid and radical improvement in their lives and the situation in the country as a whole. At the same time, the distant contours of this future are blurred and vague, and almost everything is reduced to improving the quality of life and removing the local government and factory administration.
Effects of Money Demand on Trade Balance in Nigeria
Authors: Adeyemi Oluwole Jacob , Oseni Isiaq O. , Tella Sheriffdeen A.
Published: January 2021

Previous studies appear to have concentrated on the effects of currency depreciation on trade balance and macroeconomic policy, while the relationship between money demand and trade balance is scantly documented in the literature. This paper therefore examines the effects of money demand on trade balance in Nigeria. For the analysis conducted, annual time series data covering the period ranging from 1986 to 2018 were used along with the Autoregressive Distributed Lag (ARDL) estimation technique. The long‑run coefficient of money demand was positively signed and statistically significant at 5% level. The positive relationship exhibited by the coefficient of money demand in the long run had a significant influence on trade balance. Thus, this implied that a unit percent increase in money demand would lead to a 1.57% significant increase in trade balance. The implication of this finding was that money demand had significantly influenced trade balance, enhancing the production of goods and fostering investment, which had led to increased growth. The paper recommends that the Central Bank of Nigeria through the Monetary Policy Committee should amend qualitative and quantitative credit control policies with the aim of improving lending to enhance the flow of credit to the real and exporting sector of the economy in order to bring about the desired effect on trade balance. However, the study is limited to an analysis of the existence of the relationship between money demand and trade balance using the Nigerian data set.
Literatur als Medium des Gedächtnisses: "Pojln" von Jehiel Isaiah Trunk
Authors: Sitarz Magdalena
Published: January 2021

Das autobiographisch gefärbte siebenbändige Werk Pojln von Jehiel Isaiah Trunk liefert ein breites Bild des Lebens der polnischen Juden von der zweiten Hälfte des 19. Jhd.s bis zum Zweiten Weltkrieg. Es kann zugleich als Medium des kollektiven Gedächtnisses betrachtet werden, dessen Rolle nach dem Khurbn sehr oft gerade die jüdischen literarischen Werke übernehmen mussten. Trunks Autobiographie gewinnt für den Leser zusätzlich dadurch an Bedeutung, weil der Autor, der nicht nur Schriftsteller, sondern auch Literaturkritiker war, in den Einführungen zum ersten sowie zum letzten Band seine Überlegungen zu Form und Zielen der autobiographischen Literatur darlegt.

THE CONCEPT OF MASLAHAH IN ISLAMIC FINANCIAL LITERACY AMONG YOUTH IN BANK NEGARA MALAYSIA MUSEUM ART AND GALLERY
Authors: Mahphoth Mohd Halim , Sulaiman Zuraidah
Published: January 2021

The effort to enhance financial literacy has become extremely important and is complementary to the initiative by Consumer Credit Act in order to strengthen the credit consumer protection framework in Malaysia. Therefore, Bank Negara Malaysia Museum Art and Gallery (BNM MAG) educates the public through exhibits that foster visitors’ understanding of financial knowledge especially the Sharia compliant matters at their Islamic Finance Gallery. This study examined the relationships between satisfying experiences and generic learning outcomes of youth visitors at BNM MAG. The study examined three key satisfying experiences that had significant and positive effects on the generic learning outcomes of youth visitors including affective, cognitive and sensory experiences. However, social experiences were not significant towards generic learning outcomes on youth visitors. This study provides insights and drive efforts to promote effective delivery of financial education initiatives to Malaysians in a sustainable manner. The authors expect that policymakers or museum managers could make use of the findings to improve Malaysians’ financial literacy in general, thus helping Malaysians making informed financial decisions. The study contributes to the advancement of Islamic financial education for the youth with the purpose of improving creative and productive attitudes.Upaya meningkatkan literasi keuangan menjadi sangat krusial dan mendukung inisiasi Undang-Undang Kredit Konsumen untuk memperkuat kerangka perlindungan kredit konsumen di Malaysia.

Epidemiological aspects and a current approach to the problem of carbon monoxide poisoning
Authors: Indiaminov Sayit I. , Kim Antonina A.
Published: January 2021

Background: Carbon monoxide (CO) poisoning is the leading cause of death from poisoning (accidental and intentional). The number of cases of CO poisoning is increasing day by day.
Aims: The aim of the study was to analyze the epidemiological situation of CO poisoning and identify the urgent aspects of this problem. In the article, the author provided a retrospective analysis of 117 cases of CO poisoning, registered in a number of regional branches of the Republican Scientific and Practical Center of the Forensic Medical Examination of Uzbekistan, after he studied and analyzed the world literature on the epidemiology of CO poisoning. It has been revealed that fatal poisoning ranks third after mechanical injuries and mechanical asphyxia and constitutes 6.3% (513 cases) in the range of deaths by violence (8078 cases). Therefore, CO poisoning is considered as one of the most prevailing (51%) causes of mortality.
Conclusion: This is a global problem, with young males at risk. Further studies on the current clinical and forensic aspects of CO poisoning are required, and the necessity for regular analysis of epidemiological data for taking comprehensive measures to prevent CO poisoning is emphasized.

Authors: Kachkovsky M. A. , Vvedenskaya I. P. , Vvedensky V. Yu. , Supilnikov A. A. , Ponomareva J. V. , Milyakova M. N.
Published: January 2021

Many questions remain in the diagnosis, treatment, and prevention of dyslipidemia, despite the available clinical recommendations. Among these issues is the cause of cardiovascular diseases, when achieving and maintaining the target values of lipid metabolism. We need to change the existing paradigm. Apolipoproteins as protein components of lipoproteins can significantly more accurately characterize the dyslipidemic status of a patient, since their structure and composition are unique. A personalized strategy for the prevention and treatment of dyslipidemia is possible based on the apolipoprotein profile. At present, new data on the functions of apolipoproteins, their genetic polymorphisms, and molecular preparations for correcting their content and lipid metabolism have been proposed.

Authors: Tonyan A. G. , Muslimov R. Sh. , Zhdamarova O. I.
Published: January 2021

It is generally accepted that the diagnostic criteria for hemodynamically significant compression of the left renal vein are the anteroposterior size of the renal vein determined by ultrasound examination in the narrowed area of 1.5–2.5 mm or less. Purpose of the study: determine the features of the work of the aorto-mesenteric "forceps" on the basis of mathematical analysis. A polypositional ultrasound examination of the kidneys, renal arteries and veins was carried out in 6 positions (standing, sitting, on the back, on the stomach, on the right and left sides). The parameters of the aorto-mesenteric "forceps" (AMP) were determined on the basis of ultrasound and mathematical analysis. Research results: In different positions of the body, the velocity indicators of arterial and venous blood flow, the diameter of the renal (PV) vein in the main part, at the gate and in the AMP change. Pressure fluctuations in the left renal vein are position-dependent and are a factor influencing the work of the aorto-mesenteric forceps.

Innovations and Economic Output Scale with Social Interactions in the Workforce
Authors: Painter Deryc T. , Shutters Shade T. , Wentz Elizabeth
Published: January 2021

The COVID-19 pandemic of 2020 changed the way we interact and engage in commerce at a fundamental level. Social distancing and stay-at-home orders leave businesses and cities wondering what economic activity will look like in the future. Given a likely reduction in face-to-face interactions, it is important to better understand how social interactivity influences economic outcomes. Here we measure the effect of social interactions in the workforce on patent production and economic efficiency. We decompose U.S. occupations into individual work activities, determine which of those activities are associated with face-to-face interactions, and reaggregate the labor force of each U.S. metropolitan statistical area (MSA) into a metric of social interactiveness. We then calculate each MSA’s density of social work activities and find that this measure is more highly correlated with an MSA’s per capita patent production than simple population density. This suggests that density of face-to-face interactions is the important driver of a city’s rate of invention. We close by exploring analogies between the development of cities and the development of stars, suggesting ways these analogies may help frame future research on cities.

Published: January 2021

To quantify the time-varying reproduction number (Rt) for Malaysia using the COVID-19 incidence data., we used data the from the Johns Hopkins University Center for Systems Science and Engineering (JHU CCSE) Coronavirus repository. Day 1 was taken from the first assumed local transmission of COVID-19. Data was split into four intervals: a) Interval 1: from Day 1 to Day 10 MCO 1, b) Interval 2: from Day 1 to Day 10 MCO 2, c) Interval 3: from Day 1 to Day 10 MCO 3 and d) Interval 4: from Day 1 to Day 10 MCO 4. We estimated the Rt using the EpiEstim package. The means for Rt at Day 1, Day 5 and Day 10 for all MCOs ranged between 0.665 to 1.147. The average Rt gradually decreased in MCO 1 and MCO 2. However, Rt increased in MCO 3 before stabilized around 0.8 in MCO 4. MCO 1 and MCO 2 which were stricter coincide with the gradual reduction of Rt. However, the more relaxed MCO 3 and MCO 4 correspond to a slight increase in the Rt before it stabilized.

Authors:   Landscape Architecture, School of Planning Design and Construction, Corr Dustin L.
Published: January 2021

Abstract. Scholars, governmental agencies, and concerned citizens are interested in developing empirical predictive models to quantitatively assess the vegetative productivity potentials of reconstructed soils (neo- sols). This research presents equations for a northern Michigan mining region in the Upper Peninsula of Michigan, based on data derived from the National Resources Conservation Service. We employed principal component analysis to develop models to predict the vegetative productivity of corn, corn silage, oats, alfalfa/hay, Irish potatoes, red maple (Acer rubrum L.), white spruce (Picea glauca [Moench] Voss), red pine (Pinus resinosa Aniton), eastern white pine (Pinus strobus L.), jack pine (Pinus banksiana Lamb.), and lilac (Syringa vulgaris L.). Soil attributes that were examined in this research include: available water holding capacity, moist bulk density, % clay, % rock fragments, hydraulic conductivity, % organic matter, soil reactivity, % slope, and topographic position. Four predictive equations based on landscape topography have been developed and are described as an all-mesic woody plant and crop equation, a xeric equation, an equation specific to jack pine, and a wet environment equation. The models were highly significant (p<0.0001) and explained 87.93%, 74.52%, 65.33%, and 87.68% of the variation in site productivity of the respective landscape setting. These equations are intended to assist in efforts to assess the vegetative productivity potentials of reconstructed soils on post-mined landscapes and other disturbed landscapes.

Quantifying the Effects of Hip Surgery on the Sphericity of the Femoral Head in Patients with Mucopolysaccharidosis Type I
Authors: van der Veer Eline L. , Gielis Willem Paul , Weinans Harry , Beek Erik J. , van Hasselt Peter M. , Sakkers Ralph J.B.
Published: January 2021

Background:

The introduction of stem cell transplantation has improved life expectancy and cognitive outcome in patients with mucopolysaccharidosis I, but this condition remains associated with substantial residual disease in several parts of the body. Many patients have hip dysplasia with progressive medial flattening of the femoral head. Quantitative evidence on the effect of surgery on remodeling to sphericity of flattened femoral heads is lacking. In the present study, we used statistical shape modeling to quantify the effect of hip surgery on the sphericity of the femoral head in patients with mucopolysaccharidosis I.

Methods:

We performed a retrospective case control study involving a series of 23 patients with hip dysplasia due to mucopolysaccharidosis I. Surgery was not offered to the first 11 children (control group). Following a change in treatment protocol, the next 12 children underwent bilateral proximal femoral varus derotation osteotomy and Pemberton osteotomy for the treatment of acetabular dysplasia with progressive femoral head flattening (surgery group). The surgery and control groups were compared with a reference group of patients with normal hips. Statistical shape modeling was used to quantify the shape of the femoral head (i.e., flattening and/or roundness of the epiphysis).

Results:

The mean age at the time of stem cell transplantation in the surgery and control groups was comparable (1.2 years). The mean age at the time of surgical intervention was 5.5 years, and mean duration of postoperative follow-up was 3.3 years. Statistical shape modeling showed variations within the total group in terms of medial indentation, width, height, and sphericity of the femoral heads. In contrast to the progressive femoral head flattening in the control group, the surgery group showed improvement of the sphericity of the femoral head after surgery. The overall shape characteristics of the femoral head in the surgery group were similar to those of the reference group of patients with normal hips.

Conclusions:

To our knowledge, this is the first study in patients with mucopolysaccharidosis I that has shown quantitative remodeling of the dysplastic, flattened femoral head to normal sphericity after increasing containment of the femoral head.

Lifetime Risk of Revision Hip Replacement Surgery in Australia Remains Low
Authors: Ackerman Ilana N. , Busija Ljoudmila , Lorimer Michelle , de Steiger Richard , Graves Stephen E.
Published: January 2021

Background:

Well-validated data from arthroplasty registries provide an opportunity to understand contemporary use of revision hip replacement at a national level. Such information can underpin health-care resource allocation and surgical workforce planning. The purposes of the present study were to describe the demographic characteristics of patients managed with revision hip replacement surgery in Australia and to examine changes in the lifetime risk of revision hip replacement over a decade.

Methods:

Deidentified individual-level data on all revision hip replacement procedures performed in Australia from 2007 to 2017 were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Life tables and population data were sourced from the Australian Bureau of Statistics. The lifetime risk of revision surgery each year was estimated with use of a standardized approach, with separate calculations for males and females.

Results:

A total of 46,086 revision hip replacement procedures were performed from 2007 to 2017. The median age at the time of surgery was 72 years (interquartile range, 63 to 80 years). While loosening or lysis became less frequent reasons for revision over time (from 51% in 2007 to 28% in 2017), revision hip replacement for infection became increasingly common (from 14% in 2007 to 25% in 2017). Revisions for metal-related pathology peaked in 2011. Utilization rates were highest for males ≥80 years of age (127.9 procedures per 100,000 population in 2017). Although a small rise was evident in 2011 and 2012 (to 2.39% and 2.22%, respectively), the lifetime risk of revision hip replacement in females decreased from 1.90% (95% confidence interval [CI], 1.82% to 1.99%) in 2007 to 1.74% (95% CI, 1.66% to 1.82%) in 2017. A similar pattern was evident for males; the lifetime risk was 1.78% (95% CI, 1.69% to 1.86%) in 2007 and 1.57% (95% CI, 1.49% to 1.65%) in 2017.

Conclusions:

These data enable us to understand the epidemiology of revision hip replacement in Australia, including the shifting clinical indications for this procedure. At a population level, the lifetime risk of revision hip replacement remains low at <1 in 50 people in 2017. These methods can be utilized for population-level surveillance of revision burden and to enable between-country benchmarking.

Opioid Use Following Inpatient Versus Outpatient Total Joint Arthroplasty
Authors: Varady Nathan H. , Smith Eric L. , Clarkson Samuel J. , Niu Ruijia , Freccero David M. , Chen Antonia F.
Published: January 2021

Background:

Although the risks of continued opioid use following inpatient total joint arthroplasty (TJA) have been well-studied, these risks in the outpatient setting are not well known. The purpose of the present study was to characterize opioid use following outpatient compared with inpatient TJA.

Methods:

In this retrospective cohort study, opioid-naïve patients who underwent inpatient or outpatient (no overnight stay) primary, elective TJA from 2007 to 2017 were identified within a large national commercial-claims insurance database. For inclusion in the study, patients had to have been continuously enrolled in the database for ≥12 months prior to and ≥6 months after the TJA procedure. Multivariable analyses controlling for demographics, geography, procedure, year, and comorbidities were utilized to determine the association between surgical setting and risk of persistent opioid use, defined as the patient still filling new opioid prescriptions >90 days postoperatively.

Results:

We identified a total of 92,506 opioid-naïve TJA patients, of whom 57,183 (61.8%) underwent total knee arthroplasty (TKA). Overall, 7,342 patients (7.9%) underwent an outpatient TJA procedure, including 4,194 outpatient TKAs. Outpatient TJA was associated with reduced surgical opioid prescribing (78.9% compared with 87.6% for inpatient procedures; p < 0.001). Among the 80,393 patients (86.9%) who received surgical opioids, the total amount of opioids prescribed (in morphine milligram equivalents) was similar between inpatient (median, 750; interquartile range, 450 to 1,200) and outpatient procedures (median, 750; interquartile range, 450 to 1,140; p = 0.47); however, inpatient TJA patients were significantly more likely to still be taking opioids after 90 days postoperatively (11.4% compared with 9.0% for outpatient procedures; p < 0.001). These results persisted in adjusted analysis (adjusted odds ratio, 1.13; 95% confidence interval, 1.03 to 1.24; p = 0.01).

Conclusions:

Outpatient TJA patients who received opioid prescriptions were prescribed a similar amount of opioids as those undergoing inpatient TJA procedures, but were significantly less likely to become persistent opioid users, even when controlling for patient factors. Outpatient TJA, as compared with inpatient TJA, does not appear to be a risk factor for new opioid dependence, and these findings support the continued transition to the outpatient-TJA model for lower-risk patients.

Tarsal Coalition of the Cuneiforms in a Young Athlete
Authors: Johnson Alexander J. , Gokcen Eric
Published: January 2021

Case:

Tarsal coalitions are relatively common, but there are no reports of cuneiform-to cuneiform coalition in the English language literature. The authors present a case of medial-to-intermediate cuneiform coalition in a young female track athlete. Previous nonoperative treatments had been unsuccessful. Coalition release and medial-intermediate cuneiform arthrodesis enabled her to return initially to full athletic participation without pain, but she had return of pain that persists despite removal of hardware.

Conclusion:

Medial-intermediate cuneiform coalition is rare. Surgery in this patient provided a short period of pain-free athletic participation, but long-term outcomes are not proven, and further research is needed.

Authors: van Buul G.M. , Thompson E. , Lutchumun R. , O'Toole G. , O'Donnell T.
Published: January 2021

Case:

This report describes a case of pediatric femoral head chondroblastoma, which was initially treated by minimally invasive curettage. At the 18-month follow-up, a subsequent osteochondral defect occurred, which was treated with a partial articular resurfacing system. At 5.5 years follow-up, he was symptom-free with minor degenerative x-ray changes.

Conclusion:

We describe a technique of focal anatomic hip resurfacing using the HemiCAP system in a pediatric chondroblastoma patient who presented with an osteochondral defect after primary curettage. This approach yielded good short-term to midterm results and is a potential alternative to total hip arthroplasty in young patients.

Authors: khalaila soltan , Coreanu Tara , Vodonos Alina , Kloog Itai , Shtein Alexandra , Colwell Lauren E. , Novack Victor , Tsumi Erez
Published: January 2021

Background: Numerous studies have confirmed the association of ambient temperature and air pollution with a higher risk of morbidities, yet few have addressed their effect on the ocular system. The purpose of this study was to assess the association between temperature, air pollution, and emergency room visits for conjunctivitis.Methods: In this case-crossover study, the records of all emergency room visits to Soroka University Medical Center (SUMC) from 2009 to 2014 were reviewed for patients with conjunctivitis. Daily exposure to fine and coarse particulate matter and temperature were determined by a hybrid model involving satellite sensors.Results: 6001 patients were diagnosed with conjunctivitis in the SUMC emergency room. We discovered a positive association between temperature increments and incidence of conjunctivitis. The strongest effect was found during summer and autumn, with an immediate (lag0) incidence increase of 8.1% for each 1 °C increase in temperature (OR 1.088 95%CI 1.046;1.132) between 24 and 28 °C in the summer and 7.2% for each 1 °C increase in temperature (OR 1.072 95%CI 1.036;1.108) between 13 and 23 °C in the autumn. There was no statistically significant association between fine and coarse particulate matter and conjunctivitis incidence.Conclusion: Temperature increases during summer and autumn are significantly associated with an increased risk of conjunctivitis. Conjunctivitis is not associated with non-anthropogenic air pollution. These findings may help community clinics and hospital emergency rooms better predict conjunctivitis cases and will hopefully lead to improved prevention efforts that will lower the financial burden on both the individual and the public.
The importance of patient engagement to quality of breast cancer care and health related quality of life: a cross-sectional study among Latina breast cancer survivors in rural and urban communities
Authors: Bonilla Jackie , Escalera Cristian , Santoyo-Olsson Jasmine , Samayoa Cathy , Ortiz Carmen , Stewart Anita L. , Napoles Anna Maria
Published: January 2021

Background: Compared to their white counterparts, Latina breast cancer survivors experience poorer quality of care and worse health-related quality of life. Limited English proficiency (LEP) and patient engagement in cancer care could help explain these disparities. We assessed associations between LEP status and difficulty engaging with physicians, with self-reported quality of breast cancer care and health-related quality of life (physical and emotional well-being) among rural and urban Latina breast cancer survivors. Methods: Analyses used cross-sectional baseline survey data from two studies that tested a stress management program among rural and urban Latina breast cancer survivors in California. Medical information was collected through medical records review. Linear regression models examined bivariate and multivariable associations of LEP status (yes or no), difficulty engaging with doctors (asking questions and participating in treatment decisions) (1-4; higher score=greater difficulty), and rural versus urban site, with three outcomes: 1) quality of breast cancer care and information; 2) physical well-being; and 3) and emotional well-being, controlling for demographic and medical factors. Results: The total sample included 304 women (151 from urban and 153 from rural sites). Mean age was 52.7 years (SD 10.9). Most were limited English proficient (84.5%) and had less than a high school education (67.8%). Difficulty engaging with doctors was inversely associated with patient ratings of quality of breast cancer care and information (B = - 0.190, p=0.014), emotional well-being (B = -1.866, p <0.0001), and physical well-being (B = -1.272, p = 0.002), controlling for demographic and treatment factors. LEP (vs. not; B = 1.987, p = 0.040) was independently associated with physical well-being only. Rural/urban status was not related independently to any outcome.Conclusions: Rural and urban Latina breast cancer survivors who report greater difficulty engaging with physicians experienced worse quality of breast cancer care and health-related quality of life. Promoting greater engagement of Latina breast cancer survivors in cancer care and providing medical interpreters when needed could improve patient outcomes among this vulnerable group.Trial registration: http://www.ClinicalTrials.gov identifier NCT02931552 and NCT01383174.

The lowermost mantle right above the core-mantle boundary shows a complex and heterogeneous landscape containing multiple poorly understood seismic features visible across a wide range of length scales. The smallest, but most extreme, heterogeneities yet observed are 'Ultra-Low Velocity Zones' (ULVZ), several of which have recently been linked to the base of mantle plumes. We exploit seismic shear waves that diffract along the core-mantle boundary to provide new insight into these enigmatic structures. We demonstrate that these waves have a strong frequency-dependent sensitivity to structure at different length scales above the core-mantle boundary, similar to the dispersive characteristics of surface waves. We measure a rare core-diffracted signal refracted by a ULVZ at the base of the Hawaiian mantle plume at unprecedented high frequencies. This signal shows remarkably longer time delays compared to lower frequencies, indicating extreme internal variability within the Hawaiian ULVZ. Utilizing the latest computational advances in 3D synthetic waveform modeling, we are able to model this high frequency signal and constrain high-resolution structure on the scale of kilometers at the core-mantle boundary, for the first time. Results reveal that the lowermost part of the Hawaiian ULVZ is extremely reduced in shear wave velocity, by up to -40%. This new observation suggests a chemically distinct ULVZ with increasing iron content towards the core-mantle boundary, which has implications for Earth’s early evolutionary history and core-mantle interaction.
Delivering and implementing child and adolescent mental health training for mental health and allied professionals: A systematic review and qualitative meta-aggregation
Authors: Banwell Emily , Humphrey Neil , Qualter Pamela
Published: January 2021

Background:
The increasing prevalence of mental health difficulties among children and young people (CYP) suggests that early intervention is vital. A comprehensive system of care and support requires the involvement of mental health professionals, including psychologists and psychiatrists, and allied professionals, including teachers, police, and youth workers. A critical starting point is the provision of effective training, in order that these professionals can better support the mental health needs of the CYP that they encounter.
Objectives:
Given the primacy of training in the CYP mental health support system, understanding the factors that maximise potential gains and facilitate uptake is pertinent. The current review therefore located and explored qualitative research evidence, to identify the barriers and facilitators underpinning successful delivery and implementation of training focussed on the mental health of CYP, for both mental health and allied professionals.
Methods:
A systematic review and qualitative meta-aggregation were conducted, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Systematic searches were carried out using ASSIA, EMBASE, MEDLINE, NICE Evidence, PsycINFO, and Scopus databases, for papers published between 2000 and 2020. 12,448 records were identified, of which 39 were eligible for review. The records were appraised for quality using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and synthesised using the qualitative meta-aggregation method.
Results:
182 raw findings were extracted from the 39 papers, which were condensed into 47 sub-categories, 19 categories, and finally 5 synthesis statements. These synthesis statements reflected the barriers and facilitators influencing the training delivery process (“support”; “content, design, and planning”), and the implementation of training into the workplace (“context”; “perceived value”; “organisational factors”).
Conclusions:
The synthesis statements and underlying categories provide practical recommendations for those designing, delivering, or implementing CYP mental health training. The review provides a robust evidence-based foundation to “common-sense” principles, drawing them into a coherent and organised framework using a synthesis method grounded in pragmatism.

Stereodynamical Control of Nonadiabatic Quenching Dynamics of OH(A2S+) by H2: Full-Dimensional Quantum Dynamics
Authors: Zhao Bin , Han Shanyu , Malbon Christopher , Manthe Uwe , Yarkony David , Guo H.
Published: January 2021

The breakdown of the Born-Oppenheimer approximation is omnipresent in chemistry, but our detailed understanding of the nonadiabatic dynamics is still incomplete. In the present work, nonadiabatic quenching of electronically excited OH(A2S+) molecules by H2 molecules is investigated by a full-dimensional quantum dynamical method using a high quality diabatic potential energy matrix. Good agreement with experiment is found for the OH(X2P) ro-vibrational and L-doublet distributions. Furthermore, the nonadiabatic dynamics is shown to be controlled by stereodynamics, namely the orientation of the two reactants. The uncovering of a major (in)elastic channel, neglected in all previous analyses, resolves a long-standing experiment-theory disagreement concerning the branching ratio of the two electronic quenching channels.

For billions of years photosynthetic microbes have evolved under the variable exposure to sunlight in diverse ecosystems and microhabitats all over our planet. Their abilities to dynamically respond to alterations of the luminous intensity, including phototaxis, surface association and diurnal cell cycles, are pivotal for survival, far more than any other environmental cues. If these strategies fail in the absence of light, the microbes can still sustain essential metabolic functionalities and motility by switching their energy production from photosynthesis to oxygen respiration. For suspensions of motile microbes above a critical density we demonstrate that this switch reversibly controls collective microbial aggregation. Aerobic respiration dominates over photosynthesis in conditions of low light, which causes the microbial motility to sensitively depend on the local availability of oxygen. For dense microbial populations in self-generated oxygen gradients, microfluidic experiments and continuum theory based on a reaction-diffusion mechanism show that oxygen-regulated motility enables the collective emergence of highly localized regions of high and low cell densities.

The implementation of nano-engineered composite oxides opens up the way towards the development of a novel class of superior energy materials. Vertically aligned nanocomposites are characterized by a coherent, dense array of vertical interfaces, which allows for the extension of local effects to the whole volume of the material. Here, we use such a unique architecture to fabricate highly electrochemically active nanocomposites of lanthanum strontium manganite and doped ceria with unprecedented stability and straight applicability as functional layers in solid state energy devices. Direct evidence of synergistic local effects for enhancing the electrochemical performance, stemming from the highly ordered phase alternation, is given here for the first time using atom-probe tomography combined with oxygen isotopic exchange. Interface-induced cationic substitution, enabling lattice stabilization, is presented as the origin of the observed long-term stability. These findings reveal a novel route for materials nano-engineering based on the coexistence between local disorder and long-range arrangement.

Background Growing large crop monocultures and heavily using pesticides enhances the chance of evolution of pesticide-insensitive pests and pathogens. To reduce pesticide use in crop cultivation, the application of priming-active compounds (PrimACs) is a welcome alternative. PrimACs strengthen the plant immune system and can thus help to protect plants with lower amounts of pesticides. PrimACs can be identified, for example, by their capacity to enhance the respiratory activity of parsley cells in culture as determined by the oxygen transfer rate (OTR) using the respiration activity monitoring system (RAMOS) or its miniaturized version, µRAMOS. The latter was designed for with suspensions of bacteria and yeast cells in microtiter plates (MTPs). So far, RAMOS or µRAMOS have not been applied to adult plants or seedlings which would overcome the limitation of (µ)RAMOS to plant suspension cell cultures. Results In this work, we introduce a modified µRAMOS for analysis of plant seedlings. The novel device allows illuminating the seedlings and records the respiratory activity in each well of a 48-well MTP. To validate the suitability of the setup for identifying novel PrimAC in Arabidopsis thaliana, seedlings were grown in MTP for seven days and treated with the known PrimAC salicylic acid (SA; positive control) and the PrimAC candidate methyl 1-(3,4-dihydroxyphenyl)-2-oxocyclopentane-1-carboxylate (Tyr020). Twenty-eight h after treatment, the seedlings were elicited with flg22, a 22-amino acid peptide of bacterial flagellin. Upon elicitation, the respiratory activity was monitored. The evaluation of the OTR course reveals Tyr020 as a likely PrimAC. The priming-inducing activity of Tyr020 was confirmed using molecular biological analyses in A. thaliana seedlings. Conclusion We disclose the suitability of µRAMOS for identifying PrimACs in plant seedlings. The difference in OTR during a night period between primed and unprimed plants was clearly distinguishable after elicitation with flg22. Thus, it has been shown, that the µRAMOS device can be used for a reliable screening for PrimACs in plant seedlings.
