Recording One’s Own Oral Culture: A Case Study of Locals’ Notebooks

Interest towards communities characterized by oral tradition has taken the form of ethnological and/or anthropological field research on this topic over the past two centuries. With the invention of the tape recorder, the difficulty of recording field information was reduced as it enabled real-time recording of testimonies provided by informants; the process became even more accessible once digital information storage became available. In parallel with the efforts of the researcher—outsider—to document realities considered relevant for the culture of traditional societies, some of the insiders became aware of the need to write down such information, which they recognized to be defining for their own social group. This article thus focuses on a particular practice in writing down ethnographic information, namely the existence of notebooks in which oral texts of different types and with different functions are recorded. To build the argument, I draw on the example of such notebooks held by the Folklore Archive of the West University of Timișoara, namely five manuscripts signed by Gheorghe Andraș, a teacher from Sânnicolau Mare, a small town in western Romania. Written in the first half of the twentieth century, these notebooks are statements of the inner calling their author felt to write down this type of ethnographic information, under the influence of national policies supporting ethnographic field research.

Occurrence of Chlamydia spp. in Conjunctival Samples of Stray Cats in Timișoara Municipality, Western Romania.

Despite the widespread public health concern about stray cats serving as reservoirs for zoonotic agents, little is known about the effect of urban and peri-urban landscapes on exposure risk. We conducted this study to monitor the presence of Chlamydia spp. in stray cats, with or without conjunctivitis, living in Timișoara Municipality, Western Romania, using staining and PCR methods. A total of 95 cats were enrolled, and conjunctival samples were harvested from 68 clinically healthy cats and another 27 cats presenting with clinical signs of conjunctivitis. Overall, we found that 65.3% (62/95) of the cats tested positive for Chlamydia spp. by PCR. Chlamydia spp. were detected in 45/95 conjunctival samples using a standard Giemsa stain, compared with 62/95 using PCR (Cohen's kappa index = 0.308; p = 0.0640). Of the cats that tested positive by PCR, 72.6% (45/62) were asymptomatic, and another 27.4% (17/62) expressed clinical signs of conjunctivitis. We found no significant difference between (p > 0.05) the distribution of infection and the recorded epidemiological data (sex, breed, age, territorial distribution, or sampling season). However, the Chlamydia spp. detection frequency was significantly higher in asymptomatic than in symptomatic cats (p = 0.0383). The obtained results increase the level of concern and awareness about the possible zoonotic potential of this pathogen and highlight that urban stray cats can be essential sources of feline chlamydiosis.

Screening for the Detection of Toxoplasma gondii IgG, IgM and IgA in Females of Reproductive Age from Western Romania.

Toxoplasma gondii, a zoonotic protozoan parasite, has the capacity to infect the fetus if the pregnant woman primarily acquires the infection during pregnancy. We evaluated the prevalence of T. gondii IgG, IgM and IgA antibodies in women of reproductive age residing in Western Romania. We also assessed the value of adding a T. gondii IgA test to the serologic panel for the diagnosis of toxoplasmosis, including the detection of a recently acquired infection. Serologic testing to demonstrate the presence of T. gondii IgG antibodies was conducted in 1317 females aged 15-45 years. T. gondii IgM and IgA antibody tests were performed in those with detectable IgG antibodies and IgG avidity test was performed if IgM and/or IgA screening test results were positive. T. gondii IgG were detected in 607 (46.09%; 95%CI: 43.41-48.79) of 1317 study participants and IgG seroprevalence tended to increase with age from 35.44% (95%CI: 29.89-41.30) in age group 15-24 years to 62.85% (95%CI: 56.57-68.82) in age group 35-45 years, showing a significant age-associated increase (p < 0.001). Of the 607 persons with detectable T. gondii IgG antibodies, T. gondii IgM antibodies were demonstrated in 8.90% (95%CI: 6.88-11.43), T. gondii IgA in 1.65% (95%CI: 0.90-3.01) and both T. gondii IgM and IgA in 0.99% (95%CI: 0.45-2.14). The prevalence of IgA antibodies tended to decrease with increasing avidity, from 75% (95%CI: 19.41-99.37) in samples with low avidity to 11.76% (95%CI: 4.44-23.87) in those with high avidity (p = 0.01). Of the study participants who were positive for both T. gondii IgM and IgA antibodies, 66.67% had low or equivocal IgG avidity test results compared to 6.25% who tested positive for IgM, were negative for IgA and in whom low or equivocal IgG avidity test results were noted (p = 0.001). This study indicates that in Western Romania, T. gondii IgG seroprevalence is high in females of reproductive age and T. gondii IgA antibodies may be rarely detected during a serologic screening. However, in individuals with demonstrable T. gondii IgG and IgM antibodies, testing for T. gondii IgA may improve the rate for the detection of a recently acquired toxoplasmosis.

Attitudes towards COVID‑19 vaccination in patients with cancer: A cross‑sectional study of 12 oncology centers.

Patients with cancer are a high-priority population for COVID-19 vaccination, as per guideline recommendations. The present cross-sectional study was performed to assess the perception of patients with cancer from Romania regarding COVID-19 vaccines. The study included 932 patients with solid and hematologic malignancies. This was a multicenter study including 12 oncology centers located in Western and Northwestern Romania. Between December 2021 and January 2022, patients with cancer completed an individual paper questionnaire regarding acceptance of the SARS-CoV-2 vaccination, type of vaccine, side effects and source of information. During the first year of the vaccination campaign in Romania, 58.05% (541/932) of the investigated patients received COVID-19 vaccines. The vaccination rate was highest in the 61-70 year age group (61.22%). The most frequently used vaccine was Pfizer-BioNTech (72%). There was a statistically significant association between the rate of vaccination and the area of residence and level of education (P<0.001), with rural residence and a lower level of education being predictive factors for COVID-19 vaccination hesitancy. Patients living in rural areas used non-medical sources (e.g. mass media, social platforms) as their main source of information (53.40%, 204/382), whereas patients living in urban areas (64.90%, 357/550) used predominantly medical sources (e.g. recommendations from oncologists and general practitioners). The main source of information among non-vaccinated patients was mass media (e.g. television, radio); 72.38% vs. 29.67% among vaccinated patients. For the latter, the primary source of information was the recommendations made by oncologists (59.70%) and general practitioners (56.76%). The most commonly reported side effect was injection site pain (20-33% for the first dose and 5-27% for the second dose). In conclusion, the present study confirmed that patients with cancer may be reluctant to receive a COVID-19 vaccine, mainly due to the fear of its potential side effects. Although there is scientific evidence to support the efficacy and safety of vaccines, the primary source of information for patients may affect vaccine uptake, thus affecting the efforts to stop the pandemic. Furthermore, the present study revealed that non-vaccinated patients preferred mass media as their main source of information, whereas vaccinated patients relied on the recommendations made by oncologists or general practitioners.

Left Ventricular Remodeling and Heart Failure Predictors in Acute Myocardial Infarction Patients with Preserved Left Ventricular Ejection Fraction after Successful Percutaneous Intervention in Western Romania.

Simple SummaryAcute myocardial infarction patients are at high risk for heart failure, even after successful revascularization therapy. We performed a study that aimed to identify early predictors of heart failure after myocardial infarction. The study included 244 patients discharged with a normal heart function after their first myocardial infarction. At the 2- year follow-up, we found that 186 (76%) showed an improvement in left ventricular function and 61 (24%) had a deterioration of the latter. Comparing the two groups, we found patients in the latter group were older, more often hypertensive, smokers, and had more severe clinical presentations of the acute myocardial infarction and more extensive coronary disease. A total of 19 patients (8%) had experienced hospitalizations for heart failure, 6% being from group I and 12 % from group II, and this difference was notable. We observed that the presence of heart failure at the admission for acute myocardial infarction and abnormal deformation patterns of the infarct-related myocardial segments detected by echocardiography accurately predicted the occurrence of heart failure during the next two years. The presence of these parameters might enable a better risk-stratification and initiation of an effective preventive therapy in acute myocardial infarction patients.(1) Acute myocardial infarction (AMI) patients are at risk of left ventricular (LV) remodeling and heart failure (HF), even after successful revascularization by percutaneous coronary intervention (PCI). We wanted to assess the independent predictors of these outcomes in AMI patients. (2) Methods: The study enrolled patients with a LVEF ≥50% after a successful PCI for their first AMI. After 24 months, patients were separated into two groups based on whether their LVEF remained ≥50% (group I), or decreased to <50% (group II). (3) Outcomes: 26% of the patients experienced a decrease in LVEF below 50%, 41% showed LV remodeling, and 8% had experienced HF hospitalizations. HF hospitalizations were significantly more frequent in group II patients (p < 0.0001). The Killip class at admission >2, infarct-related longitudinal strain ≤−12.5%, and the presence of LV remodeling were identified as independent predictors of HF hospitalizations. (4) Conclusions: About 26% of AMI patients with normal LV function after a successful PCI developed HF. More sensitive techniques are required that allow for a more efficient risk-stratification and preventive therapy to reduce LV remodeling and HF in AMI patients with LVEF ≥50% after a successful PCI. The detection of abnormal ventricular deformation patterns after PCI by speckle-tracking echocardiography might be a valuable method in this approach.

Management of the Western Corn Rootworm (D. v. virgifera) in Corn Cultivation System

In managing the corn crop, European farmers frequently face the presence of the pest Diabrotica v. virgifera, which has a negative impact on production. Since 1992, various attempts have been made to limit its expansion and multiplication. In recent years, with the elimination of the most used chemical insecticides, farmers had to resort to non-aggressive and less polluting methods. Therefore, in this paper, an attempt was made to find a solution available to anyone to reduce the adult population level in maize crops. Knowing that adults are responsible for long-distance movements, it was deemed appropriate to focus on the use of both colored and pheromone traps for detection, monitoring and capture. The testing of the traps was carried out in 2020 and 2021, between June and September in two culture systems, organic and classic, belonging to an agricultural company from an area of interest in Western Romania. Following these studies, it was found that in the ecological culture, corn catches were 1.8 times higher than in the classic culture. Dual-attractant (color and sex pheromone) pheromone traps were the most effective in both crop types, with a capture efficiency of 90.65% of capacity, while in colored traps without sex pheromone it was only 60.0%. Pheromone-only traps had intermediate efficiency, with a capture capacity of 72.68%. In conclusion, traps with double attractiveness, both in color and in the presence of pheromone, are a viable solution in managing the pest.

Laryngeal malignancies - epidemiological data and particularities of the cases diagnosed in Western Romania (October 2016-July 2020).

In the last decade, the incidence and mortality associated with laryngeal malignancies has experienced an unfavorable evolution in Romania, in terms of this pathology the country that has become the leader, among the European Union (EU)-27 countries. The aim of the present retrospective study was to analyze the epidemiological data regarding laryngeal cancer and histopathological (HP) particularities in patients diagnosed in Western Romania. Within three years and 10 months (during October 2016-July 2020) in Ear, Nose and Throat (ENT) Clinic of Timişoara Municipal Emergency Clinical Hospital, 194 patients with laryngeal neoplasms (LN) were diagnosed. Most of the patients were male (93.8%), from Timiş County, mainly and the neighboring Counties of Caraş-Severin, Hunedoara, Mehedinţi and Arad. Patient's average age (both sexes) was 62.6 years, with a range from 38 to 84 years and the highest percentages in the 60+ age group (48%). Regarding smoker status, the main cause of the development of the LN, 93.9% of patients were active ones. Regarding localization [International Classification of Diseases 11th Revision (ICD-11)], about 69% were malignant neoplasm of glottis (C32.0), followed by supraglottis (C32.1), larynx-unspecified (C32.9), and subglottis (C32.2). From the HP point of view, several types of tumors were identified, most of which were non-keratinized and keratinized squamous cell carcinomas (about 90%). In addition, there were identified types of verrucous carcinoma, acantholytic carcinoma, squamous papilloma, a possible pleomorphic sarcoma, and pyogenic granuloma. The data presented in this study highlight the growing incidence of LN, which mainly affect men, at an increasingly young age. It is imperative to involve specialists from nutrition, general medicine, ENT, dentistry to start awareness programs and to develop prevention protocols.

Biological Profile and Clinical Features as Determinants for Prolonged Hospitalization in Adult Patients with Measles: A Monocentric Study in Western Romania.

Measles is a highly infectious and sometimes deadly illness that is preventable with vaccination. The present research aims to analyze the most recent measles epidemic from Romania that occurred in a population with a falling desire to receive immunizations, by detailing the clinical picture and biological profile of hospitalized patients. A secondary goal of the present research is to identify characteristics that increase the likelihood of a longer hospitalization and the development of measles-related pneumonia. A retrospective cohort study was conducted to follow the course and effects of measles virus infection in adult hospitalized patients who were divided into two groups based on whether they had been in the hospital for more than 6 days or fewer than 6 days. A total of 114 adult patients with measles were eligible to participate in the trial if they had a positive measles-specific IgM antibody test resulting from the study. The average age in the short hospital stay group was 28.1 years, while the average age in the long hospital stay group was 31.9 years. There was a statistically significant difference in the number of Roma persons in the research groups, with 17.4 percent of them having a lengthy hospital stay compared to 5.9 percent in the group with a short hospital stay, according to the findings. It was observed that many patients had a long hospitalization associated with chronic lung disease (OR = 1.07), liver damage (OR = 1.66), Roma ethnicity (OR = 1.79), a long duration elapsed from the last MMR dose (OR = 2.02), elevated c-reactive protein (OR = 2.17), the presence of bilateral pulmonary condensations on X-ray (OR = 3.13), and elevated procalcitonin (OR = 3.49). The same significant independent risk factors were also associated with the development of pneumonia. It is of imperative need to address these risk factors in a patient with measles, moreover in association with an unknown status of vaccination. Vaccination awareness against measles must be pushed in Romania to determine a higher than 95% coverage. Significant efforts are still needed to ensure improved protection against measles epidemics within a specific region or population and, more importantly, in patients with significant risk factors for complications, as described in this study.

Modelers of students' entrepreneurial intention during the COVID-19 pandemic and post-pandemic times: The role of entrepreneurial university environment.

This paper examines the shaping factors, drivers, and impact credentials of students’ entrepreneurial intention during the COVID-19 pandemic. The proposed framework addresses the antecedents of entrepreneurial intention among students in Romania, focusing on three focal constructs, namely, risk-taking, proactiveness, and innovativeness, with a keen focus on the mediation effect of the entrepreneurial university environment. The study used self-reported data collected through an online questionnaire during November 2020–February 2021 from a sample of 1,411 students in western Romania. The methodology relies on two modern techniques of modeling cross-sectional data, namely, structural equation modeling (SEM) and Gaussian graphical models (GGMs). The main results highlight that the three constructs positively relate to students’ entrepreneurial intention in a comprehensive framework where the entrepreneurial university environment drives innovativeness. The paper brings forward, in an innovative way, that entrepreneurship education and training at the university level enhance students’ entrepreneurial intentions as it fosters the attainment of advanced knowledge and skills. The results are well associated with the start-up process as prerequisites for successful entrepreneurship engagement of youth in a globalized digital economy, particularly during this challenging pandemic outbreak, but also post-pandemic times. This research sheds new light on the essential role played by higher education institutions in providing advanced knowledge and necessary skills matched with the labor market needs, thus enhancing students’ innovativeness and their entrepreneurial intentions.

"THE WALNUT SHIELD BEARER COPTODISCA LUCIFLUELLA (CLEMENS, 1860) (LEPIDOPTERA: HELIOZELIDAE) – THE FIRST RECORD IN ROMANIA THE WALNUT SHIELD BEARER COPTODISCA LUCIFLUELLA (CLEMENS, 1860) (LEPIDOPTERA: HELIOZELIDAE) – THE FIRST RECORD IN ROMANIA THE WALNUT SHIELD BEARER COPTODISCA LUCIFLUELLA (CLEMENS, 1860) (LEPIDOPTERA: HELIOZELIDAE) – THE FIRST RECORD IN ROMANIA THE WALNUT SHIELD BEARER COPTODISCA LUCIFLUELLA (CLEMENS, 1860) (LEPIDOPTERA: HELIOZELIDAE) – THE

" The invasive species Coptodisca lucifluella, also called the walnut shield bearer is recorded for the first time in Romania in this report. It is a leaf miner of North American origin, having been discovered for the first time in Europe (Italy) in 2010. Since then it has been confirmed in other three European countries, Hungary (2017), Ukraine (2019) and Bulgaria (2020), and now in Romania. In its native habitats, the species is known to be specialized on woody plants from the family Juglandaceae, genus Carya, in particular the pecan nut tree, Carya illinoinensis (Wangenh.) K. Koch. In the newly occupied territories in Europe, the moth was reported mainly on Juglans spp., especially J. regia (L.) (with very few instances on Juglans nigra (L.), Carya spp. and Pterocarya spp.). In August 2022, leaves of common walnut (J. regia) with mines of C. lucifluella were collected in Southern Romania (Bucharest, Ilfov and Giurgiu Counties) and Western Romania (Arad County). The walnuts were in cities, rural areas, alongside roads and walnuts spontaneously grown in vineyards, at altitudes from 60 to 200 m a.s.l."

Evaluation of FIB-4, NFS, APRI and Liver Function Tests as Predictors for SARS-CoV-2 Infection in the Elderly Population: A Matched Case-Control Analysis.

Several investigations have revealed that COVID-19 causes a significant death rate due to acute respiratory distress syndrome, alterations in the quantity of ACE2 receptor expression, or the intensity of cytokine storm. Similarly, patients with hepatic impairment that are co-infected with SARS-CoV-2 are more likely to display upregulations of ACE2 receptors and cytokine storm overload, which exacerbates hepatic impairment, potentially increasing the death rate. Moreover, it is expected that the aging population develops a higher degree of hepatic fibrosis in association with other comorbid conditions that are likely to influence the course of COVID-19. Therefore, this research was developed to describe the differences in liver test parameters in elderly individuals with COVID-19 in relation to other inflammatory markers and outcomes. This current observational single-center research followed a case-control design of elderly patients hospitalized for SARS-CoV-2 infection. The research was conducted at a tertiary emergency hospital in western Romania during a two-year period. There were 632 patients included in the analysis that were split into two equal groups matched 1:1 based on gender and body mass index. Three hundred sixteen patients made the group of cases with COVID-19 patients older than 65 years, while the other half were the 316 patient controls with COVID-19 that were younger than 65 years old. Disease outcomes showed a higher prevalence of ICU admissions (22.8% vs. 12.7%, p-value < 0.001) and in-hospital mortality (17.1% vs. 8.9%, p-value = 0.002) in the group of cases. Specific and non-specific liver biomarkers were identified as risk factors for mortality in the elderly, such as ALP (OR = 1.26), LDH (OR = 1.68), AST (OR = 1.98), and ALT (OR = 2.34). Similarly, patients with APRI and NFS scores higher than 1.5 were, respectively, 2.69 times and, 3.05 times more likely to die from COVID-19, and patients with FIB-4 scores higher than 3.25 were 3.13 times more likely to die during hospitalization for SARS-CoV-2 infection. Our research indicates that abnormally increased liver biomarkers and high liver fibrosis scores are related to a worse prognosis in SARS-CoV-2 infected individuals.

A new ornithopod dinosaur, Transylvanosaurus platycephalus gen. et sp. nov. (Dinosauria: Ornithischia), from the Upper Cretaceous of the Haţeg Basin, Romania

ABSTRACT Rhabdodontid dinosaurs were a group of medium-sized iguanodontian ornithopods from the Late Cretaceous of Europe. The uppermost Cretaceous continental deposits from the Haţeg Basin of western Romania yielded a very rich assemblage of vertebrates including abundant rhabdodontid remains, which have been exclusively referred to the genus Zalmoxes thus far. Here we describe a new rhabdodontid dinosaur, Transylvanosaurus platycephalus gen. et sp. nov., from the uppermost Cretaceous of the Haţeg Basin. The holotype of the new taxon was discovered in early–late Maastrichtian strata near Pui in the eastern part of the basin and comprises the articulated basicranium and both frontals. Transylvanosaurus differs from all previously reported rhabdodontids in having particularly wide and crested frontals, elongated and straight paroccipital processes that make only a gentle lateral curve and project mostly posterolaterally, prominent and massive prootic processes that extend mainly anterolaterally and ventrally, wide and crest-like basal tubera that meet the long axis of the braincase at a very flat angle, widely splayed basipterygoid processes that extend mainly ventrolaterally and slightly anteriorly, as well as a well-developed notch on the lateral side of the basicranium that is continuous, straight, and inclined anteroventrally. Phylogenetic analyses employing two different datasets consistently recovered the new taxon within the Rhabdodontidae, at the base of the iguanodontian radiation. Based on the morphological comparisons presented herein, we propose a particularly close relationship between Transylvanosaurus and Rhabdodon from southern France, which in turn provides evidence for a more complex biogeographic history of the Rhabdodontidae than previously thought.

Aurignacian dynamics in Southeastern Europe based on spatial analysis, sediment geochemistry, raw materials, lithic analysis, and use-wear from Românești-Dumbrăvița

The Aurignacian is one of the first cultural-technological traditions commonly associated with the expansion of Homo sapiens in Europe. Early Homo sapiens demographics across the continent are therefore typically inferred using the distribution of Aurignacian assemblages. Western Romania has been used as a tie-point to connect the well-researched lithic assemblages from the eastern Mediterranean and Western Europe through its early Homo sapiens fossils. However, Romania’s archeological record remains underexplored thereby hindering our ability to directly connect better understood regions through time and space. Here we report on excavations from the open-air Middle/Upper Paleolithic site of Românești-Dumbrăvița I in southwestern Romania. Three stratified Paleolithic assemblages were extensively excavated within a 1-m-thick eolian-deposited sequence. Spatial, geochemical, raw material, techno-typological, and use-wear analysis of the site reveal patterns of artifact configuration, resource exploitation, fire history, knapping objectives, and functionality. Taken together, Românești-Dumbrăvița I is the first well-contextualized archeological site in close spatiotemporal proximity to many early, well-preserved human fossils and in East-Central Europe.

Defining a Precipitation Stable Isotope Framework in the Wider Carpathian Region

The eastern part of Europe is very poorly represented in the Global Network for Isotopes in Precipitation (GNIP) database, mainly because the monitoring of the stable isotopes in precipitation started only recently compared with other regions. In this respect, the main objective of this article is to fill the gap in the GNIP database over the eastern part of Europe and show the temporal variability and potential drivers of an extended network of δ18O values in precipitation collected from 27 locations in Romania and the Republic of Moldova. We also present the first high-resolution map of the spatio-temporal distribution of δ18O values in precipitation in Romania and the Republic of Moldova, according to an observational dataset. According to our results, the stations from western and northern Romania tend to have LMWLS with higher values than those from southwestern Romania. The monthly variation of the δ18O and δ2H showed a clearly interannual variation, with distinct seasonal differences, following the seasonal temperatures. The analysis of the spatial distribution of stable isotopes in precipitation water was made on the basis of both observational data and modeled data. This allowed us to study the origin of the air moisture and the interaction with regional and local patterns and to analyze the link between the spatial δ18O variations and the large-scale circulation patterns on a seasonal scale.

RESEARCH ON THE EVALUATION OF TUBER YIELD COMPONENTS IN SOME POTATO VARIETIES (Solanum tuberosum L.) UNDER THE CONDITIONS OF AGRICULTURAL RESEARCH AND DEVELOPMENT STATION FROM LOVRIN, ROMANIA

Potato (Solanum tuberosum L.) is considered "the second bread of the country" due to the use of tubers in a wide range of foods and in the production of potato flakes, chips, and flour. It is also an important raw material for the alcohol, starch, glucose, dextrin etc. industry. The biological material used in the research consisted in 14 Romanian potato varieties developed in laboratories specialized in this species, namely: the National Institute of Research and Development for Potato and Sugar Beet from Braşov (cv. 'Asinaria', 'Cezarina', 'Sevastia', 'Brașovia', 'Castrum', 'Marvis', 'Sarmis' and 'Ervant'), and the Potato Research and Development Station from Târgu-Secuiesc (cv. 'Albioana', 'Armonia', 'Nemere', 'Productiv', 'Redsec' and 'Gared'). Experimental potato varieties were included in a monofactorial comparative culture, according to the four-replication randomized block method. The area of the experimental parcel was determined by the number of plants (200 plants / variant) and planting scheme. Thus, the number of plants per area unit was depended on the maturity group, namely: midlle early varieties (47,600 plants / ha; 0.70 m between rows x 0.30 m between plants / row), midlle late varieties (40,800 plants / ha; 0.70 m between rows x 0.35 m between plants / row) and late varieties (35,700 plants / ha; 0.70 m between rows x 0.40 m between plants / row). From the comparative analysis of morphological characters (number of tubers / hills) and yield (average tuber weight, yield per hill and area unit) one can highlight the following genotypes depending on maturity group, namely: midlle early Asinaria variety, and midlle late 'Albioana', 'Braşovia', 'Productiv', and 'Sarmis' potato varieties. Taking into account the costs of potato culture and the production price for consumption potatoes in pedo-climatic conditions in western Romania, efficient productions of over 45 t/ha (yield/ha of tubers φ &gt; 55 mm) are required.

Navigating the Digital World - the Impact on the New World of Work, A Multigen Perspective

Digital technology impacts the 21st century, and it shapes our lifestyle, the way we think and the way we act. This paper presents aspects of the digital transformation of the workplace and how this process requires the creation and development of new skills and competencies for employees today but especially in the future. In this new context, an essential role is played by education, by educational systems that need to adapt to new requirements, precisely so that educators have the skills needed to be more productive. From this perspective, in the paper, the authors present a teaching and learning method called the TADEO method, which encourages learning the skills needed for Education 4.0. This method is based on a technology support software tool to help teachers build their teaching plan, teaching duration, teaching materials, and assessment method. Hybrid work is an opportunity that brings new challenges: the work environment is changing rapidly, and automation is replacing human tasks in order for organizations to thrive. Recruitment has become complicated with the digital transformation, and new challenges are emerging for employers as they need people with the skills needed to cope with a changing work environment. The study was conducted on a sample of respondents from a multinational service company based in western Romania, where the accounting department employees were interviewed to see what they think about artificial intelligence, the implications of robots, and the future at work. This research is based on four objectives that have been achieved and three hypotheses that have been tested. The study results showed that about half (43.7%) of the employees who answered this questionnaire worked in the office. Only 28.2% consider themselves very satisfied with the job, and 37.9% see themselves working at the same company for 10 years.

The Impact of Air Pollution on Frequent Exacerbations among COPD Patients: An Observational Study on the Population of Western Romania

Patients with respiratory pathologies are the risk group most affected by air pollution, being directly exposed, especially those diagnosed with chronic obstructive pulmonary disease (COPD). In this observational study, which included 79 patients, we evaluated whether COPD patients with the frequent exacerbating phenotype or the infrequent exacerbating phenotype live in residences with higher values of air pollution. An air quality monitoring station was installed in each patient’s house for at least 24 h and PM 1.0, PM 2.5, and PM 10 were measured. Average PM 1.0, PM 2.5, and PM 10 values were lower in the group of infrequently exacerbating patients compared to the frequently exacerbating ones. For every 1 µg/m3 increase in the average values of PM 1.0, PM 2.5, and PM 10, there is an increase of 1.7%, 1.8% and 1%, respectively, in the risk of developing exacerbations. More importantly, an average value of PM 1.0, PM 2.5, and PM 10 above 32.21 µg/m3, 82.32 µg/m3 and 42.89 µg/m3 increases the probability of developing an exacerbation by 3.83, 10.14, and 4.12 times, respectively. Our analysis showed that COPD patients with a frequently exacerbating phenotype live in residences with high levels of air pollution compared to infrequently exacerbating ones.

A Sample of Resilient Intercultural Coexistence in Ethnic Hungarian, Serbian and Bulgarian Communities in Western Romania

This article sets out to highlight the way in which the phenomena of co-construction and territorial deconstruction make themselves apparent locally. We focused our study on Timiș County, core of the historical Banat region, for the reason that it is still an ethno-cultural mosaic linked to its cross-border space. We based our analysis on the exploitation of a specific bibliography and, especially, on a survey through questionnaire and interview. The regional socio-cultural identity of Banat was founded on the dialogue and intercultural co-construction that have been practised since 1718. The repeated processes of socio-spatial co-construction and deconstruction, due to the changes of sovereignty and limits, prove a remarkable identity resilience, Banat being a model of continuity of regional territoriality. In the current context of European integration and of regionalisation, these processes have been reactivated, with the ethnic minorities cultivating solidarity with their co-nationals over the border while also preserving solidarity with the present host country, Romania.

Antibacterial Activity of Romanian Propolis against Staphylococcus aureus Isolated from Dogs with Superficial Pyoderma: In Vitro Test.

Staphylococcal infection treatment in dogs is frequently associated with adverse side effects, high costs, prolonged treatment, and resistant strain selection. Staphylococcus aureus is the most frequently isolated staphylococci in cases of canine superficial pyoderma. The number of Staphylococcus strains to exhibit primary resistance to various drugs in vitro is increasing. Propolis has a diverse chemical composition and well-known therapeutic properties against bacterial infections. The current investigation evaluated in vitro the antimicrobial activity of the commercial allopathic antimicrobials, Romanian propolis ethanolic extracts, against clinical Staphylococcus aureus strains isolated from superficial dermatitis clinical samples in dogs and two reference strains: Staphylococcus aureus ATCC 25923 and Staphylococcus aureus ATCC 43300, as the MSSA and MRSA positive controls, respectively, in western Romania. We used the microdilution broth technique to evaluate the susceptibility profile of the bacteria. The minimum inhibitory concentration (MIC) of the Romanian propolis ethanolic extract ranged from 6 to 10 μg/mL for all isolates, determined by the broth microdilution method. The MICs of ethanolic Romanian propolis extracts had a pronounced antibacterial activity. These results indicate that propolis can potentially be used and recommended for in vivo experiments as a promising therapeutic agent against Staphylococcus aureus infections in superficial dermatitis of dogs.

Spatial and Temporal Distribution of the Island-Dwelling Kogaionidae (Mammalia, Multituberculata) in the Uppermost Cretaceous of Transylvania (Western Romania)

The latest Cretaceous kogaionid multituberculates from Transylvania (western Romania) were part of an endemic European clade of mammals that underwent an insular radiation at the end of the Cretaceous and then survived the end-Cretaceous mass extinction that extinguished many groups of contemporary therians. Transylvanian kogaionids lived on what was an island during the latest Cretaceous—“Haţeg Island”—and their fossils are found in the uppermost Campanian to upper Maastrichtian deposits of the Haţeg, Rusca Montană, and southwestern Transylvanian basins. This fossil record has improved dramatically over the past several decades, in part resulting from our decade-long joint Romanian-American-Scottish fieldwork, and comprises one of the most impressive and complete archives of Mesozoic mammals, including not only jaws and teeth but several incomplete skulls and partial skeletons. We here review the fossil record of kogaionids from Transylvania. We report four new occurrences from the Haţeg Basin, update information on previously described ones, and use our database to reassess the chronostratigraphical and geographical distribution of kogaionids and their evolutionary patterns. Although it was previously suggested that large and small kogaionids had largely mutually exclusive spatial distributions, we recognize the cooccurrence of small and large taxa in various units, suggesting a sympatric distribution across their entire chronostratigraphic range. We also identify a novel pattern: small kogaionids appear somewhat earlier than their larger relatives in all well-sampled sedimentary successions, suggesting that kogaionid colonizations of Haţeg Island and component regions took place at small body size and that body size increased only later through local evolution. We find correlations between body size, preservation style, and sedimentary context, which give insight into kogaionid paleobiology and diversity. Larger kogaionids are represented more often by partial skulls and occasionally skeletons compared with small kogaionids, which are usually represented only by isolated teeth, regardless of provenance. Larger kogaionids currently have a higher recognized local taxic diversity than their smaller relatives. We hypothesize that this may be in part a consequence of preservational bias related to body size, as more complete specimens may be more easily diagnosed as distinct taxa than those that are represented by more fragmentary and/or incomplete fossils. If true, the taxic diversity of smaller kogaionids may currently be underestimated. Finally, we identify correspondence between sedimentary facies and preservation style. Red-colored fine-grained rocks, suggestive of well-drained, oxidized floodplain paleoenvironments, yield more complete specimens than drab, greenish or grayish sediments deposited in more poorly drained parts of the floodplain. This pattern may suggest habitat preferences for better-drained floodplain environments and a semifossorial lifestyle for some taxa. As the kogaionid fossil record improves, we can further test the hypotheses and patterns outlined above. The pace of new kogaionid discoveries by our team and others indicates that a more complete picture of kogaionid distribution, paleobiology, and evolution will emerge in the coming years, contributing to a more profound understanding of this peculiar group of island-dwelling Mesozoic mammals.
