AIM: To understand the factors associated with negative conversion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA, targeted surveillance and control measures can be taken to provide scientific basis for the treatment of the disease and to improve the prognosis of the disease.
METHODS: Using the method of retrospective cohort study, we collected the data of Coronavirus Disease 2019 (COVID-19) patients in Tongji Hospital of Wuhan, China from 10 January to 25 March, 2020. Among the data of 282 cases, 271 patients, according to whether the negative conversion happened, were divided into negative conversion group and control group. We made the quantitative variables into classification; Chi-square test single-factor and Cox regression were used in univariate analysis and extracted 30 meaningful variables, then through the collinearity diagnosis, excluded the existence of collinear variables. Finally, 22 variables were included in Cox regression analysis.
RESULTS: The gender distribution was statistically significant between two groups (p < 0.05). While in the negative conversion group, the patients of non-severe group occupied a large proportion (p < 0.001). The median time for the negative conversion group was 17 days, and at the end of the observation period, the virus duration in control group was 24 days (p < 0.05). A total of 55 variables were included in univariate analysis, among which 30 variables were statistically different between the two groups. After screening variables through collinearity diagnosis, 22 variables were included in the Cox regression analysis. Last, lactate dehydrogenase (LDH), age, fibrinogen (FIB), and disease severity were associated with negative conversion of SARS-CoV-2 RNA.
CONCLUSION: Our results suggest that in the treatment of COVID-19, focus on the age of more than 65 years old, severe, high level of LDH, FIB patients, and take some targeted treatment, such as controlling of inflammation, reducing organ damage, so as to provide good conditions for virus clearance in the body.
Transesophageal Evaluation of Reconstructive Surgery for Aortic Valve Stenosis
Authors: Anguseva Tanja , Mitrev Zan , Zdravkovska Milka
Published: December 2020

BACKGROUND: With transesophageal echocardiography (TEE), were evaluated morphological characteristics and early hemodynamic parameters of stentless three leaflets pericardial patch in patients with aortic stenosis (AS) undergoing aortic valve (AV) surgery.
AIM: The aim of the study was to point the importance of two-dimensional and three-dimensional TEE imaging intra and early postoperatively.
METHODS: At Zan Mitrev Clinic, 2002–2020, were included 377 patients following the actual guidelines of European Society of Cardiology for valvular disease, whereas patients with dilatation of aortic annulus, rheumatoid arthritis, and chronic program on hemodialysis were excluded from the study. Instead of using a standard prosthesis, we made a reconstructive surgery implanting three new created leaflets using bovine/equine pericardium by replacing destroyed valve cusps. Leaflets were implanted separately, using continuous sutures with two supported stitches and that is how real stentless AV without any stent or sowing ring was created. Intraoperative and post-operative TEE was performed.
RESULTS: 377 pts with aortic valvular disease (211–56% male, and 166–44% female; 82–21, 75% with AS, 32–8, 49% with aortic insufficiency, and 263–69, 76% with combined stenosis and insufficiency) were included in the study. Post-operative TEE showed aortic morphology close to normal AV, average pressure gradient was 8 mmHg. 121 pts got a combination with aortocoronary bypass (2.3 grafts per pts). 4 patients were re-operated. Mortality rate was 12.46% (44 pts). Follow-up period was 18 years.
CONCLUSIONS: Real stentless aortic bioprosthesis is with a close morphology and hemodynamic parameters as a normal valve. TEE such as tool for assessment of AV morphology, anatomy of aortic root, pre-, and intra-operative plays a pivotal role in guiding case selection, surgical planning, and in evaluating procedural success.

BACKGROUND: Mangosteen (Garcinia mangostana L.) is a plant that contains various secondary metabolite compounds, one of which is xanthone. Xanthone in mangosteen has a variety of beneficial biological and medical effects, one of which is an antioxidative, anti-inflammatory, and antiapoptotic agent.
AIM: The aim of the study was to perform the selection of any xanthone in mangosteen pericarp that have potentially inhibit the interaction of AGEs and RAGE.
METHODS: The analysis was made in silico by docking method using software Hex 8.0. The docking was done between AGEs-RAGE, also between nine active compounds of G. mangostana with RAGE. The active compounds analyzed here were including α-mangostin, β-mangostin, γ-mangostin, mangostanol, garcinone D, 1,6-Dihydroxy-3,7-dimethoxy-2-(3-methylbut-2-enyl)-xanthone, gartanin, 1-isomangostin, and 3-isomangostin. Further analysis was performed to see the interactions formed between ligands with their receptors using software LigPlus+ and Discovery Studio 4.1.
RESULTS: 1-isomangostin, 3-isomangostin, γ-mangostin, mangostanol, D-garcinone, and gartanin have potentially could inhibit the interaction and activity of imidazole in RAGE through a competitive binding mechanism.
CONCLUSIONS: The inhibition of imidazole-RAGE activity by the mangosteen active components may inhibit the pathobiology of AGEs-RAGE axis.

Published: December 2020

BACKGROUND: Motorcycles (motorlance) are often deployed as ambulances to the scene of an emergency to reduce response time. The COVID-19 pandemic has affected emergency medical services (EMS) in Thailand in many respects, and this study was conducted to examine its effect on motorlance operation time.
AIM: The aim of the study was to examine motorlance operation time during the COVID-19 pandemic in comparison to normal periods.
METHODS: This cross-sectional study examined all EMS motorlance operations dispatched from Srinagarind Hospital (Thailand). Data were collected from the Srinagarind Hospital EMS operation database and hospital information database system. Data from June 1, 2018, to December 31, 2019 (normal period) were compared with those from January 13 to April 21, 2020 (COVID-19).
RESULTS: Eight hundred seventy-one EMS operations were examined over two periods. Mean patient age during the COVID-19 pandemic was 41.5 ± 6.2 years, and 54.6% (n = 59) were male. Average response time was 6.20 ± 1.35 min during the normal period and 3.48 ± 1.01 min during the pandemic (p = 0.021). Transport time was also significantly shorter during the latter period (2.35 vs. 5.20 min).
CONCLUSIONS: Motorlance response and transport time during the COVID-19 pandemic were significantly shorter than usual.

A propósito de la métrica de las Crestomatías de Heladio de Antínoe y su repercusión en la interpretación de la obra
Authors: Verdejo Manchado Javier
Published: December 2020

De acuerdo con Orión (s. V) y Focio (s. IX), la obra del autor egipcio del s. IV Heladio de Antínoe titulada Crestomatías presentaba una composición yámbica en alguna de sus partes. La crítica moderna, sin embargo, ha extendido este tipo de metro a toda la obra. En este artículo intentaremos demostrar que una lectura literal de las fuentes indica que estas circunscriben el uso de los yambos únicamente al prefacio. En cuanto a la forma del resto de la obra, determinados indicios, tanto señalados por las fuentes como contenidos en ella, nos llevan a pensar que estaba redactado en prosa. Finalmente, teniendo en cuenta el contenido de la obra y su estructura formal, intentaremos situar a Heladio y sus Crestomatías dentro de la historia de la literatura griega.
Ávila 1517-1519, la fundación de un pasado legendario: El Epílogo de Gonzalo de Ayora
Authors: Abeledo Manuel
Published: December 2020

Este trabajo estudia el Epílogo de algunas cosas dignas de memoria escrito por Gonzalo de Ayora para alabar la ciudad de Ávila en 1519. Está casi enteramente basado, para su parte medieval, en la Crónica de la población de Ávila, compuesta en el siglo XIII. Este trabajo analiza el modo en que Ayora utiliza su fuente, y muestra que su interés central está en el episodio de las “Hervencias”, que el autor no da mucho valor a su fuente y que la copia que usó era cercana al códice “B”. Previamente describe la editio princeps del Epílogo, sus testimonios conservados, sus copias manuscritas y sus ediciones modernas.
Una diatriba manuscrita inédita contra Política de Dios de Quevedo
Authors: Alonso Veloso María José
Published: December 2020

Este artículo pretende informar de la existencia de una invectiva inédita contra Política de Dios de Quevedo. Se copia en un manuscrito fechado en octubre de 1626 y dirigido a Antonio de Sotomayor, confesor de Felipe IV y consejero real. Quevedo pudo conocer la diatriba y aludir a ella en el prólogo de su edición autorizada de Política de Dios. La invectiva destaca en el contexto de la polémica en torno a esta obra por su extensión y su sistemática impugnación, por destinatario y alcance político: sitúa a Quevedo en el “bando contrario del privado” (Olivares) y achaca a “otra era”, la de Felipe III y Lerma, la corrupción denunciada por el escritor. Su texto permite adivinar las maniobras de enemigos del escritor, alentando en la sombra, ya en 1626, su enfrentamiento con el valido, que será definitivo a partir de 1630.

Chalumeau de Verneuil y la GRAE (1796)
Authors: Hernando García-Cervigón Alberto
Published: December 2020

En este artículo se estudia la teoría gramatical de Chalumeau de Verneuil, académico honorario de la Real Academia Española que en 1821 publica la traducción al francés de la cuarta edición de la GRAE (1796) con enmiendas y anotaciones, y añade en tomo aparte unas Remarques détachées, concebidas dentro del marco de la gramática general, con las que trata de poner el texto académico en sintonía con la gramática que se estaba haciendo por aquellos años en las naciones más adelantadas de Europa, especialmente en Francia. La obra, que produjo un gran impacto en el extranjero, fue tenida en cuenta por los miembros de la corporación en el proceso de reforma de la nueva edición de la GRAE (1854).

Published: December 2020

INTRODUCTION: Myocardial infarction (MI) is a type of cardiovascular disease. Cardiovascular disease is the major side effect of diabetes. It causes damage to heart muscle due to interruption in the blood flow. The chance of getting this disease is high in diabetes patients.OBJECTIVES: To choose a dataset with features related to diabetes, parameters of ECG and risk factors of MI for effective prediction. Predict myocardial infarction in both type-1 and type-2 diabetic patients using regression techniques. Recognise the best algorithm.METHODS: Multiple linear regression, ridge regression and lasso regression are existing techniques in addition to which proposed technique lasso regression is used to develop a model for prediction. The trained models are compared to know better performing algorithm. Estimation statistics namely confidence and prediction intervals are used to show the amount of uncertainty in predicted values. The statistical measures in regression analysis namely root mean squared error and r_squared value are used to evaluate and compare algorithms.RESULTS: The proposed algorithm ‘lasso regression’ has achieved better values of RMSE and r_squared as 0.418 and 0.2278 respectively compared to remaining techniques.CONCLUSION: Best performance of proposed algorithm was noticed and hence using lasso regression for prediction of myocardial infarction in diabetes patients gives better results.
The influence of COVID-19 on international labor migrations from Bosnia and Herzegovina to EU
Authors: Ćudić Bojan , Klemenčič Matjaž , Zupančič Jernej
Published: December 2020

The article deals with the contemporary labor migrations from Bosnia and Herzegovina to Slovenia and the other countries of European Union, specifically during the period of the COVID-19 pandemic. On the basis of fieldwork among the participants in these migrations, it seeks to identify the specifics of circumstances and situations that arose suddenly with the closure of political borders and the demands of social distancing. In these circumstances, we supposed that labor migrants found themselves to be a particularly vulnerable group of population. The case study has denied that this is completely true. On the other hand, labor migrations from Bosnia and Herzegovina to Central, Western and North European and some non-European countries have been a continuous process for the last century and at least migration flows must be taken as a fact which directions, volumes and character are greatly influenced by labor market regulations in each individual EU member and other states. Periodically, specific political and social situations also gain importance. The COVID-19 pandemic has exactly such an impact.
Think Piece: Learning, Living and Leading into Transgression – A reflection on decolonial praxis in a neoliberal world
Authors: Kulundu Injairu , McGarry Dylan Kenneth , Lotz-Sisitka Heila
Published: December 2020

Three scholar activists from South Africa reflect on what it means to transgress the limits of a neoliberal world and its crisis times, particularly considering transgressions in the service of a decolonial future. The authors explore three questions: i) What kind of learning can help us transgress the status quo? ii) How do we extend this learning into a commitment to actively living in transgressive ways? iii) What does it mean to lead in ways that re-generate a transgressive ethic in a neoliberal world? In a dialogical conversation format, the authors outline nine different but interconnected perspectives on learning, living and leading into transgression, with the aim of concurrently revealing the multiple layers of work that a decolonial future depends on, while demonstrating the ambitions of a pluriversal decolonial future through their writing. The intertwined narrative is not conclusive, as the processes marked out in brief are experiences that still need to be fully practised in new relations in times to come within academia-in-society-and-the-world with human and more-than-human actors. However, they do offer a generative set of questions, concepts and metaphors to give courage to boundary-dwelling scholar activists attempting transgressive research. These reflections seek to regenerate the transgressive ‘decolonial gestures’ (decolonialfutures.net) that we can undertake in a neo-liberal world, as an important part of environment and sustainability education practices. It draws out what an embodied practice of transgressive learning can entail when we become discerning of hegemonic discourses that reproduce the status quo. We pay homage to those decolonial scholars in the field of environment and sustainability education as we traverse this terrain, recognising their imagination and the transgressive movement that has come before us, but importantly we seek to also open pathways for those yet to come.

Objetivo: comparar a evolução da medida ultrassonográfica quantitativa de hipertrofia sinovial em pacientes com osteoartrite (OA) primária de joelhos submetidos a uma injeção intra-articular (IIA) de plasma rico em plaquetas (PRP) versus triancinolona hexacetonida (TH) versus solução salina (SS) em um seguimento de 52 semanas. Material e métodos: foi realizado um estudo randomizado, controlado, duplo-cego com 100 pacientes divididos em três grupos: grupo PRP (preparado de PRP autólogo), grupo TH (40 mg – 2 ml de TH) e grupo SS (2 ml de SS a 0,9%). Os pacientes foram avaliados por um radiologista “cego” em T0, 4, 8, 12 e 52 semanas após a IIA através das medidas ultrassonográficas quantitativas longitudinal e transversal de hipertrofia sinovial no joelho estudado. Utilizou-se significância estatística de 5%. Resultados: dos 100 pacientes, 90 eram mulheres, 83 eram brancos, com média de idade de 66,13 (6,5) anos e tempo médio de sintomas de 8,13 (5,9) anos. A medida ultrassonográfica longitudinal apresentou melhora estatística para todos os grupos (intragrupo) apenas entre o T8 e o T52. A medida transversal apresentou melhora estatística para os três grupos (intragrupo) de T0 a T12. No entanto, não houve diferença estatística entre os grupos para nenhuma das duas medidas ultrassonográficas. Conclusão: apesar da melhora intragrupo em relação ao T0, não houve diferença estatístic a na evolução das medidas ultrassonográficas quantitativas de hipertrofia sinovial quando comparados pacientes com OA de joelhos que receberam uma IIA de PRP versus TH versus SS.

O reumatologista e a ultrassonografia
Authors: Bonfiglioli Karina Rossi
Published: December 2020

A utilização da ultrassonografia na reumatologia teve seu primeiro registro em 1978. Expandiu-se na década de 1990, com a utilização do power Doppler e, atualmente, já faz parte da formação do reumatologista em diversos países. No Brasil, a técnica, embora difundida no meio reumatológico, ainda não é amplamente disponível. A exemplo do que ocorreu em outras especialidades médicas, o valor da informação agregada ao método fez com que este se tornasse parte da avaliação clínica e extensão do exame físico. O potencial da ultrassonografia na avaliação clínica está consolidado. Cursos de capacitação e aprimoramento, dentro das diretrizes internacionalmente estabelecidas pelo OMERACT (Outcome Measures in Rheumatology), são necessários para garantir os desfechos clínicos desejados.

Comparative study of the Effectiveness of the use of the universal tennis elbow splint compared to elbow brace in treatment of Lateral Epicondylitis
Authors: Pote Dr. Uday B. , Solge Aishwarya , Karpe Vaishnavi , Ghare Mihir A , Thatte Antara A
Published: December 2020

Background: Lateral epicondylitis is a serious condition affecting 1 to 3% of adult population between the age group of 30 to 50 year old. This group represents the working force and tennis elbow causes debilitating pain and patients are unable to perform the affected limb functions of lifting or holding anything. The main cause for tennis elbow is the tendinopathy of the extensor carpi radialis brevis muscle (ECRB). There are multiple treatment measures to relieve the pain and bring back the function of the limb to normalcy as early as possible. The elbow brace is used to reduce the expansion of the ECRB and thereby reducing the symptoms of tennis elbow. It was hypothesized that wrist splints would reduce the activation of the ECRB muscle and thereby will reduce the symptoms of the tennis elbow. Streek et al performed a study using the wrist splint with 20-30 degrees extension and mentioned in limitations the changing the degree of extension may improve outcomes as compared to elbow braces. On that hypothesis we used a brace with only 5-10 degrees of extension. Aims: 1) To study the symptomatic and functional outcome of the elbow brace. 2) To study the symptomatic and functional outcome of the wrist splint. 3) To compare the symptomatic and functional outcomes between the wrist splint and the elbow brace. Material & Methods: The patients included in the study were divided into Group A receiving the wrist splint and group B elbow brace. The patient rated tennis elbow evaluation score (PRTEE), grip strength and pain visual assisted (VAS) score on the day of enrolment and 6 weeks after using either the elbow brace or wrist splint was noted. We used Mann-Whitney U test to calculate P-value intergroup and for P-value intra-group we used Wilcoxon’s signed rank test. Result: Group A distribution of median 6 weeks PRTEE score improved significantly compared to median baseline PRTEE score (P-value<0.001). The VAS score, grip strength and improvement in PRTEE score at 6 weeks is relatively better in Group A compared to Group B, however the difference did not reach statistical significance (P-value>0.05).Conclusion: The use of wrist splint significantly improved the symptoms of the tennis elbow. The outcome is comparable to use of tennis elbow brace. The outcome is not statistically significant if compared between the two groups.

Serendipity as chaos or discovery – exploring the role of personality and sense of coherence
Authors:   Oslo Metropolitan University, Department of Archivistics, Library and Information Science, Oslo, Norway, Heinström Jannica , Sormunen Eero ,   Tampere University, Faculty of Information Technology and Communication Sciences,  Finland
Published: December 2020

Introduction. Individual differences have long been said to influence serendipity. Empirically, however, robust evidence is lacking for this connection. This study addressed this research gap by linking serendipity to personality traits and sense of coherence. Method. Data from 140 respondents was collected by an online survey. The survey measured the five-factor model personality traits, sense of coherence and serendipitously found useful and interesting information. Analysis. The data was analysed by a general linear model regression analysis. Results. Only 7% of variance of serendipity/usefulness and 10% of serendipity/interest could be explained by personality and sense of coherence. Usefulness was linked to sense of coherence (low comprehensibility), while interest was linked to personality (extraversion, agreeableness and low negative emotionality). Conclusions. Individual differences in serendipity was found both related to a negative cognitive experience of information chaos and a positive affective-behavioural experience of discovery. Lack of control over the information flow could lead to a sense that acquisition of useful information is governed by chance rather than conscious efforts. Activity, social connectedness and positive emotionality, in turn, would increase the likelihood to discover interesting information.
Support versus restriction: parents’ influence on young children’s information behaviour in connection with mobile devices
Authors:   Berlin School of Library and Information Science, Humboldt-Universität, Berlin, Germany, Schlebbe Kirsten
Published: December 2020

Introduction. This paper examines how parents perceive and mediate young children's use of mobile devices and discusses how this may affect children's information behaviour. Method. For data collection, semi-structured interviews with 22 parents from 19 families with 22 children aged one to six years who had already used mobile devices were conducted. Analysis. All interviews were audio-recorded, transcribed verbatim and analysed using the software MAXQDA. A combination of inductive and deductive coding methods was used for data analysis. Results. The analysis shows that young children engage in a great variety of information-related activities while interacting with mobile devices. The results also indicate a strong parental influence. Parents expressed positive and negative perceptions of young children's use of mobile devices and reported different enabling and restrictive mediation practices. Conclusions. By supporting children's use of mobile devices, parents enable their children to engage in activities that help them to access new information and expand their knowledge. At the same time, parents try to protect their children from risks and negative influences through restrictions. In this way, parents act as a bottleneck for children's access to information by mobile devices.

Published: December 2020

This article aims to analyze Harun Nasution's thoughts on education and its relevance to the modern world, especially in Indonesia. The method used in this research is literature study where the author tries to find, compile and analyze various information through various related sources. The results of this study explain that according to Harun Nasution, the backwardness of Muslims in Indonesia is caused by the Islamic education system which only focuses on the teachings of worship and fiqh which have implications for Islamic teachings which are interpreted as narrow and rigid teachings so that reforms in the world of Islamic education are needed by paying attention four important things, namely: (1) the educational curriculum should be prepared by taking into account the moral aspects, development and growth of students' thought processes, (2) the use of educational methods should emphasize the cultivation of moral education so that good morals are formed in children in addition to the delivery of material, (3) educators should have various competencies and constantly improve their quality, (4) religious education should produce students or students who religious spirit, not just religious knowledge. The positive impact expected in this article emphasizes the importance of moral aspects to be instilled in students to answer the problem of moral decline that is increasingly prevalent in this modern era.
Assessment of the reasonable number of physicians in Korea
Authors: Oh Young In , Lee Jung Chan , Park Jeong Hun
Published: December 2020

The government argues that the expansion of the number of physicians is inevitable due to the absolute lack of practising physicians in Korea compared to members of the Organisation for Economic Co-operation and Development. Further, the government contends that poor medical access and adverse effects on the national health level require such an expansion. This study aimed to verify whether the government’s claims regarding the lack of physician manpower are reasonable by estimating the projected supply and demand of physicians by 2023 based on scenarios involving their productivity and number of working days. As a result, all scenarios indicated a projected oversupply, except for the scenario in which there are 255 working days and physicians’ productivity is the same as that of 2018. Even in scenario three, in which there are 255 working days and physicians’ productivity is the same as that of 2018, an oversupply was projected from 2027. Standards regarding the number of physicians vary from country to country, as they are affected by various factors including medical systems, demographic structures, national health levels, medical infrastructures, accessibility, medical finance and geographical conditions. This issue can be seen as resulting from the unbalanced regional distribution of physicians rather than from an absolute shortage of the number of physicians.

The objective of this study was investigationofphysical and compositional fruits
characteristics of six chestnut cultivars. The fruits belonging to these cultivars were
subjected to physical and chemical composition determinations, and the obtained
results were comparatively analysed. It can be noticed that there are significant
differences between cultivars for all the analysed traits. A high variability was found
between cultivars in terms of nutrients content. The moisture content of chestnuts
analysed in this study ranged from 51.63% to 58.42%. The protein content recorded
values between 5.40 and 7.18% fresh matter. The polyphenols content in cultivars
taken under analysis was between 1.65 and 19.60 mg GAE/g, which is a very large
variation range between different cultivars. The obtained values of antioxidant
activity of chestnuts are high, ranging from 0.73 to 9.90 mg Trolox/g of fresh
substance, revealing also a wide variation range. Among the individual phenolic
compounds, elagic and gallic acids were determined in higher amounts. The results of this study have shown that chestnut fruits contain significant concentrations of
primary and secondary metabolites that are known for their positive effects on
human health.

The aim of this study was to assess the yield and fruits quality of plum produced
in ecological system.In 2019-2020 periods the influence of different fertilizers
(Biohumus, Macys BC 28 and Cifamin BK) on yield and fruits quality at three plum
cultivars (‘Centenar’, ‘Tita’ and ‘Stanley’) was carried out in a demonstrative plot from
Research Institute for Fruit Growing Pitești, Romania. Biohumus was applied to the
soil in increasing dosesfrom 0.5 l/tree (respectively 415 l/ha), 0.7 l/tree (respectively
585 l/ha) to 0.9 l / tree (respectively 750 l/ha) in two moments: in spring before the
start of vegetation and in autumn after the fall of the leaves.Macys BC 28 and Cifamin
BK fertilizers were applied foliar in doses of 2 l/ha, respectively 1 l/ha, in two
moments: after flowering and in the young fruit phase.As results of the investigations
we found that: the highest fruit yield was obtained at ‘Centenar’ (47.36 kg/tree) and
‘Stanley’ (41.00 kg/tree) cultivars in fertilization variant 3 (Biohumus – 0,9 l/tree, soil
application + Macys BC 28 – 2 l/ha, foliar application + Cifamin BK – 1 l/ha, foliar
application);the best results regarding the fruits weight were also obtained in the 3rd
fertilization variant (Biohumus – 0,9 l/tree, soil application + Macys BC 28 – 2 l/ha,
foliar application + Cifamin BK – 1 l/ha, foliar application), among the varieties being
noted the ‘Tita’cv. with an average fruit weight of 59. 14 g; the fruits soluble solid
content was higher in the case of the fertilized variants than in the unfertilized
variant and the fruits aciditywas higher in the case of the unfertilized variant than in
the fertilized variants.

The paper presents a 2-years study of the valuable characteristics in four
foreign apple cultivars grown in northeastern Romania, named Moldavia area. The
phenological stages, quality traits of fruits and some chemical parameters were
evaluated. Start flowering was determined at April 17th (’Resse’), while end of
flowering was identified the period April 27th -28th. Period of flowering was 9 to 12
days as average for studied years 2019-2020. Fruit’s weight have varied between
120.55 g (’Resse’) and 179.46 g (’Remo’), while fruit’s equatorial diameter have varied
between 65.82 mm and 74.87 mm at ‘Resse’ and respectively ‘Remo’, but no
statistically distinct differences registered between all studied apple cultivars. The
values of the soluble dry solids range between 14.65° Brix (‘Resse’) to 17.05° Brix
(‘Relinda’), and the total dry solids has recorded values between 17.95% (’Resse’) to
21.39% (‘Remo’). The studied apple cultivars showed variability but some got
remarked through large fruit’s size or high level of soluble dry solids.

Climatic accidents increase in frequency due to climatic changes. Hailstorms are
typically localized events and are known few studies about their effect on grapevine.
The objective of this study was to examine the vine vegetative balance responses to
natural hail, registered when shoots were 10-15 cm height. Four grape cultivars (Vitis
vinifera L.), two for red wine (Feteascǎ Neagrǎ, Pinot Noir) and two for white wine
(Chardonnay, Tǎmȃioasǎ romȃneascǎ) were studied in Dealu Mare, one of the most
known vineyards in Romania. Visibly, the extent of the hailstorm damage was great,
enough to injure or remove about 90% of shoots growth till hail fall. Three
treatments with Delfan Plus (amino-acids complex) were applied on grapevine
canopy. Number of shoots/vine and number of fertile shoots/vine were counted and
biologic balance of grapevine indexes were calculated. Our results indicated that
natural hail affect significantly the number of fertile shoots. Delfan Plus treatments
positively influenced the number of shoots and fertile shoots. Delfan Plus treatments
had little influence on Recovery index, vine Balance indexes and Ensurance
Coefficient after one single year of study. The capacity of recovery after hail fall, in
this case, is more influenced by the grape cultivar. The present work is the first
attempt to enhance our understanding on the vegetative responses of grapevines to
the use of biostimulants and to natural hail, which is an extreme and complex natural
phenomenon.
What Capital Wants: Business Interests and Labor Market Reform in Portugal and Spain
Authors: Valdez Jimena
Published: December 2020

Under what conditions are governments able to liberalize labor markets? I leverage the cases of Portugal and Spain, two countries hit by the Eurozone crisis and constrained in their policy options, that diverge in the key measure mandated by international creditors to recover – the decentralization of collective bargaining. Against the common assumption that the liberalization of labor is widely embraced by capital, I show that governments are only able to advance labor reforms when there is a leading industrial export sector that benefits from it and provides a powerful domestic social partner. I test this argument with in-depth qualitative data collected during twelve months of fieldwork in both countries, including 129 interviews with politicians, policy-makers, and members of business associations and labor confederations, among others.
Measurements to determine the mixing state of black carbon emitted from the 2017–2018 California wildfires and urban Los Angeles

Published: December 2020

Abstract. The effects of atmospheric black carbon (BC) on climate and public health have been well established, but large uncertainties remain regarding the extent of the impacts of BC at different temporal and spatial scales. These uncertainties are largely due to the heterogeneous nature of BC in terms of its spatiotemporal distribution, mixing state, and coating composition. Here, we seek to further understand the size and mixing state of BC emitted from various sources and aged over different timescales using field measurements in the Los Angeles region. We measured refractory black carbon (rBC) with a single-particle soot photometer (SP2) on Catalina Island, California (∼70 km southwest of downtown Los Angeles) during three different time periods. During the first campaign (September 2017), westerly winds were dominant and measured air masses were representative of well-aged background over the Pacific Ocean. In the second and third campaigns (December 2017 and November 2018, respectively), atypical Santa Ana wind conditions allowed us to measure biomass burning rBC (BCbb) from air masses dominated by large biomass burning events in California and fossil fuel rBC (BCff) from the Los Angeles Basin. We observed that the emissions source type heavily influenced both the size distribution of the rBC cores and the rBC mixing state. BCbb had thicker coatings and larger core diameters than BBff. We observed a mean coating thickness (CTBC) of ∼40–70 nm and a count mean diameter (CMD) of ∼120 nm for BCbb. For BCff, we observed a CTBC of ∼5–15 nm and a CMD of ∼100 nm. Our observations also provided evidence that aging led to an increased CTBC for both BCbb and BCff. Aging timescales < ∼1 d were insufficient to thickly coat freshly emitted BCff. However, CTBC for aged BCff within aged background plumes was ∼35 nm thicker than CTBC for fresh BCff. Likewise, we found that CTBC for aged BCbb was ∼18 nm thicker than CTBC for fresh BCbb. The results presented in this study highlight the wide variability in the BC mixing state and provide additional evidence that the emissions source type and aging influence rBC microphysical properties.

Abstract. In the framework of the COmbination Service for Time-variable Gravity fields (COST-G) gravity field solutions from different analysis centres are combined to provide a consolidated solution of improved quality and robustness to the user. As in many other satellite-related sciences, the correct application of background models plays a crucial role in gravity field determination. Therefore, we publish a set of data of various commonly used forces in orbit and gravity field modelling (Earth's gravity field, tides etc.) evaluated along a one day orbit arc of GRACE, together with auxiliary data to enable easy comparisons. The benchmark data is compiled with the GROOPS software by the Institute of Geodesy (IfG) at Graz University of Technology. It is intended to be used as a reference data set and provides the opportunity to test the implementation of these models at various institutions involved in orbit and gravity field determination from satellite tracking data. In view of the COST-G GRACE and GRACE Follow-On gravity field combinations, we document the outcome of the comparison of the background force models for the Bernese GNSS software from AIUB (Astronomical Institute, University of Bern), the EPOS software of the German Research Centre for Geosciences (GFZ), the GINS software, developed and maintained by the Groupe de Recherche de Géodésie Spatiale (GRGS), the GRACE-SIGMA software of the Leibniz University of Hannover (LUH) and the GRASP software also developed at LUH. We consider differences in the force modelling for GRACE (-FO) which are one order of magnitude smaller than the accelerometer noise of about 10−10 m s−2 to be negligible and formulate this as a benchmark for new analysis centres, which are interested to contribute to the COST-G initiative.
