Published: June 2022

The proficiency tests are widely used to evaluate the analytical capacity of laboratories and also as part of the accreditation processes. The National Intercomparison Program is a Proficiency Test that uses radioactive reference materials in soil, vegetation, water and air filters. This work is a study of the choice of composition of radionuclides ideal to be used in the air filters to be produced by LNMRI as reference material for PNI.
Five cocktails composed of different radionuclides chosen for their energies in the range of 30 to 2000 keV were prepared, each cocktail was distributed in three glass fiber air filters using a pantograph using the pycnometer technique, contaminating each filter with 19 (nineteen) drops, totaling fifteen (15) air filter samples, with the objective of homogeneous distribution of the droplets at the sites determined by the geometry chosen without the need for marking in the filters, in order to choose the best composition to be used in the preparation of reference material.

OBJECTIVES
There is no clear guidance on the intensity and duration of physical activity (PA) that adolescents require to maximise cardiorespiratory fitness (CRF). We aimed to determine the strength of associations between each PA intensity and CRF, independently of other intensities, and the PA duration at each intensity associated with maximal CRF.

METHODS
PA and CRF were assessed in 339 adolescents aged 13 to 14 years by wrist-worn accelerometers and 20-m shuttle runs, respectively. Partial regression modeling was used to construct residualized PA variables at each PA intensity that were uncorrelated with each other. Moving average models were optimally fitted to determine relationships between residualized PA variables and CRF. Threshold regression models determined the duration of PA above which CRF improvement was minimal.

RESULTS
Greater vigorous PA (VPA) was associated with better CRF until about 20 minutes of daily VPA, when the relationship plateaued. Moderate and light PA, and sedentary time were not associated with CRF in partial models. Adolescents performing 14 (range 12–17) minutes of daily VPA had median CRF. Participants in the upper quartile of VPA had 1.03 z-scores higher CRF than those in the lowest quartile (95% confidence interval: 0.75 to 1.30).

CONCLUSIONS
Our data suggest that 20 minutes of daily VPA may be best for maximizing CRF in adolescence. As moderate-to-vigorous PA guidelines can be satisfied by only undertaking moderate PA, with no apparent independent benefit, we suggest that future guidelines focus on VPA alone, simplifying public health messaging.

Palynology is one of the most used methods to determine the species of different plants. It acts like a fingerprint, being unique to each plant species. The aim of this paper was to observe differences both at morphological level and from the pollen viability point of view of 21 apple (Malus domestica Borkh.) and 19 plum (Prunus domestica L.) varieties, differences that can be correlated with genotype variation in further genotyping research, with the final goal of using these results as a basis for genotype-assisted breeding programs. Pollen grain (PG) morphology was assessed using a Scanning Electron Microscope and pollen viability was analyzed using in vitro germination. This study demonstrated significant differences in both the size of PGs and the percentage of viable pollen through in vitro germination. Among the apple varieties, Belle de Boskoop presented the largest PGs, and among the plum varieties Timpurii de Țurlești. Aura apple variety had the lowest viability percentage.

Published: June 2022

Scab resistance through the Rvi6 gene was largely used in Romanian breeding programs including those from Fruit Research & Development Station (FRDS) Bistrita. The aim of the study was to verify the efficacy of the resistance due to the Vf gene under the current conditions in the Bistrita area. Three scab resistant apple cultivars bred at FRDS Bistrita were monitored in the field, in comparison with the Rvi6 ‘Florina’ and ‘Prima’ cvs., and the sensitive ‘Idared’ and ‘Golden Delicious’ cvs. Molecular markers (AM-19, U1₄₀₀ and AL07) were used in PCR to check the presence of the Rvi6 gene in the genome of the three Romanian varieties. During the years 2019-2021, scab lesions appeared on all the resistant cultivars studied. PCR results showed the presence of Rvi6 gene on ‘Bistritean’, ‘Salva’, ‘Aura’, ‘Prima’ and ‘Florina’ genoms. The results suggest a possible breakdown of the resistance given by the Rvi6 gene in the current ecological conditions in this area. Scab symptoms occurring on cultivars that have the Rvi6 gene could lead to the hypothesis that different scab races are now present in our area or that some genetic variations occurred on the existing races so that they overcome Rvi6 gene.

In viticultural ecosystems, considered energy-intensive systems, the amplification of biocoenotic imbalances with the onset of pest explosions, is a problem and also an evidence of the biodiversity’s decline. In this study the biodiversity was quantified in Târnave vineyard, in the period 2016-2018, in the experimental plots of SCDVV Blaj cultivated with the Fetească regală cultivar, for two cultivation technologies, the extensive agroecological (EA) and the intensive conventional (IC). The determined biodiversity characterization indicators were: the species richness, Simpson biodiversity index (D), Shanon biodiversity index (H) and Equity index (E). In case of the Heteroptera group EA technology doubled the number of the arthropods (11.333 ± 0.882 for EA versus 5.33 ± 1.453 for IC). The reverse effect was observed for Coleoptera were in the case of EA it was found a taxa richness of 8.667 ± 0.882 and for IC one of 15.667 ± 1.764. Considering the increase of the number of useful species from the order Heteroptera in the agroecological variant compared to the conventional variant, we consider that the implementation of the agroecological technology for a longer period (5-10 years) can be a long-term solution that will contribute to reducing the risk induced by the intensive practices, while reducing the dependence of culture on conventional energy resources.

В статье исследуются актуальные проблемы творческой деятельности, считающейся высшим проявлением мыслительного процесса. В ракурсе конституционных реформ предлагается пересмотреть конституционные нормы о свободе творчества на основе международно-правовых стандартов, закрепить обязанности государства по всемерной защите прав интеллектуальной собственности. В частности, авторы утверждают, что в последнее время наравне с человеком субъектом творческой деятельности становится самодостаточный и саморазвивающийся искусственный интеллект, который создает оригинальные и уникальные научные произведения. В этой связи он вполне может претендовать на статус субъекта интеллектуальной деятельности. Исследуя некоторые вопросы плагиата и самоплагиата, авторы подвергают критическому анализу чрезмерные и формальные строгости, установленные в правилах проведения экспертиз диссертационных исследований, и предлагают дифференцировать плагиат и самоплагиат.

Aim To evaluate the efficacy of remote monitoring by the compliance with body weight control and drug therapy in patients with CHF, using a specially developed software module for chronic heart failure (CHF) monitoring.Material and methods During 2018–2020, 79 patients with dilated cardiomyopathy (mean age, 36.1 [34.2; 38.4] years) and NYHA II-IV functional class CHF were included in the outpatient telemonitoring (TM) program.Results The duration of monitoring was 965 [768; 1065] days. During the monitoring time, the compliance with outpatient body weight control significantly improved: 73.3 [70; 80] % at baseline vs. 86.7 [76.7; 86.7] % at the end of the 31st month (p<0.001). The proportion of patients measuring their body weight at least 6 times a week significantly increased: 8.9 % at baseline vs. 58.1 % by the end of the monitoring (p<0.001). There was no significant association between the time-related changes in the compliance with body weight control and drug therapy and the patient’s gender. In addition, during long-term TM, a small but statistically significant increase in left ventricular ejection fraction was noted (36.3 [35.5; 37.2] % at baseline vs. 37.2 [35.8; 38.3] % at the end of monitoring; p=0.0008). The involvement of staff physicians in the remote correction of therapy for CHF decreased during the study: the number of system notifications that required a physician’s response reduced over two years from 26.6 to 13 % (p=0.011).Conclusion Participation of patients with dilated cardiomyopathy and CHF in the structured TM program was associated with a significant increase in the compliance with regular self-control of body weight and drug therapy for heart failure.

Background: The aim of the study was to analyse clinical, biochemical parameters and treatment outcomes of COVID-19 patients with vascular disease.Methods: Retrospective analysis of data of COVID patients from May 2020 until July 2021.Results: 7 patients had arterial disease alone, 3 arterial and venous, 4 venous alone. Mean age of patients with arterial disease was 52. 80% were diabetic, 30% hypertensive, 30% thyroid disorders. 10% past CVA, 10% had past PAD history. 10% had history of tobacco consumption. 50% had severe and 20% had moderate COVID, 30% were post discharge. Mean duration of presentation was 20.1±18.6 days after COVID diagnosis; mean duration of symptoms 8.8±11.8 days. 50% femoro-popliteal segment and 20% iliac segment was involved. 10% each were subclavian, axillary and brachial occlusions. Mean±SD CRP, ESR and D-dimer at admission were 74.36±71.35, 97±38.5 and 1360±1538 respectively. 3 surgical, 1 medical intervention resulted in limb salvage in 4 patients (9.25 month follow up; 2 upper, 2 lower limb). 3 patients required trans-tibial or above amputations. Death occurred in 2 patients. The four patients with COVID induced VTE had no comorbidities, presented mean 5.75 days of symptom onset; COVID diagnosis mean 23.33 days prior. External iliac to popliteal vein was the most common pattern (75%). Mean CRP and ESR were lower than in the arterial cases. One patient underwent IVC filter placement and CDT; for another IVC filter was placed. All four were discharged uneventfully.Conclusions: Patients who developed arterial disease mostly had comorbidities, more severe COVID disease and higher mean inflammatory markers.

Instrument separation is one of the most stressful endodontic mishaps, that can occur any time during the root canal treatment. Several techniques have been employed to facilitate instrument retrieval, however, most of them are technique sensitive, expensive and require great expertise. Through this paper, an economic and convenient technique is suggested to retrieve the fractured segment with a combination of both hand files and sonic agitation. A 35 year old male patient presented with pain in lower anterior tooth region. Clinical examination revealed an intact PFM (Porcelain fused to metal) crown in 31 with no soft tissue abnormality and radio-visio-graph indicated a fractured H-file fragment extending from the apical third to 2 mm beyond the radiographic apex with an associated radiolucency. Thus, a retreatment aimed at retrieval of the fractured instrument followed by obturation and post endo restoration was planned without removing the fixed prosthesis. It was possible to successfully remove broken file from the root canal using Sonic agitation coupled with H files with minimal damage to radicular dentin.

Published: June 2022

Background: Semiarid lands possess limitations of climate such as low and erratic rainfall, long dry spell, high potential evapotranspiration and lesser length of growing period which directly influence the yield and productivity of crop along with the soil properties. Pigeon pea, being one of the most dominant pulse crops cultivated in the semiarid Deccan plateau, an understanding on the soils where pigeon pea is mainly grown and the evaluation of their land suitability was found to be essential. Methods: Land resource inventory at 1:10,000 scale was carried out in Mahabubnagar Rural mandal, Mahabubnagar district, Telangana state of South Deccan plateau to characterize the major pigeon pea growing soils and their land suitability evaluation. Result: When the entire study area was evaluated for its suitability, majority of the area (32.79%) was marginally suitable, followed by moderately suitable area (16.24%) with moderate to severe limitations of nutrient availability, rooting conditions, gravelliness and texture and a very small area of 5.55 per cent was found to be highly suitable towards the crop. Out of the 18 soil series identified, only five were the major pigeon pea soils which were mostly marginally suitable (S3) with limitations of nutrient availability, slope, effective root depth and texture. Though the climatic characteristics of the area were highly favourable to the crop classified under the highly suitable class (S1), rooting conditions, nutrient availability and slope were the major limitations towards the cultivation and productivity of pigeon pea.

Higher-order thinking skills are the ability of students to analyze, evaluate, and create. Students with good higher-order thinking skills will have the drive to think broadly and deeply about the subject matter and be able to solve contextual problems based on critical and rational arguments. The results of observations of the mathematics learning process at the research site indicate that students tend to be less active in participating in learning, so high-level learning outcomes tend to be unsatisfactory. To solve these problems, the researchers made improvements to the quality of education by implementing the think pair share model. The learning improvement process was carried out in two cycles. The progress in learning indicates that students' learning activities and higher-order thinking skills have increased. Students' learning activities have grown from the initial cycle to the final stage of the learning process. The improvement in learning also shows that students' higher-order thinking skills have increased after taking action. Higher-order thinking skills of students have improved from the initial cycle to the final stage, with the average value in the initial cycle, cycle 1, and cycle 2, respectively, being 35, 55, 95. The average higher-order thinking skill has increased from the initial stage to the final stage, from the initial condition to cycle 1 of 57.14%, and cycle 1 to cycle 2 of 72.73%. The research results obtained are under the indicators of research success, namely improving learning through implementing the think pair share model, successfully increasing learning activities, and students' higher-order thinking skills.
