Research data on pavement particle retention for D6.5
<p>We tested the hypothesis that porous asphalt would be able to retain more dust (including microplastics) in its pore network than conventional dense asphalt. Hence, the collection of pore dust was done on the four sections of the carousel to compare among pavements and according to the number of cycles. This is because the different sections will experience the same weather conditions, such as precipitation, wind speeds or dust deposits.</p><p>Dust was collected each time the carousel stopped (at 0, 20,000, 50,000, 100,000, 200,000, 500,000, 750,000 and 1,000,000 cycles) using a specially designed vacuum cleaner. This equipment was used thanks to a collaboration with CSIC. Based on the laboratory results, this equipment is able to recover the particles not only on the surface but also those inside accessible pores. The area vacuumed per section was initially 30 x 5 cm2, then 30 x 15 cm2 to increase the sample size. Samples were collected both in the wheel track area and in an outer ring separated from the circulated zone. The samples are weighted and referenced to the sampling area.</p><p>Collected dust samples were stored in individual containers and sent to the laboratory of the UC to process them by thermogravimetric analysis (TGA) and SEM for their microplastics contents. </p>

Research Survey on 'Effects of the Coronavirus Pandemic on Scientific Research'
<p><strong>1. The aim of the research</strong></p><p>The survey aimed to collect opinions on how the pandemic has changed scientific research, especially in regards to the usage of different forms of digital tools. The onset of COVID-19 has had an immediate impact on how scientists were able to use their time and resources to do their work. However, there was a lack of real-time data on how they are responding to this event and how it has had differential impacts across scientific fields.</p><p><strong>2. Research instrument and subject</strong></p><p>A survey questionnaire prepared in English was developed for collecting empirical data from academics in Poland and abroad. We used the same version of the survey questionnaire both in Poland and in other countries in the world. The survey questionnaire consisted of several parts. Its first part included questions on demographic information. The second part of the survey questionnaire contained questions about how respondents' work hours were allocated for different activities during, and after the coronavirus pandemic outbreak and the predicted changes in future publication and funding related to spending on researching, writing during and after the coronavirus pandemic. The last part of the survey questionnaire included questions about scientific works, their quality, and support by ICTs during the coronavirus pandemic, as well as the implications of the pandemic for these issues in the future. At the end of the survey questionnaire, we asked respondents about their opinions with regard to the forecast situation in research and education after the coronavirus pandemic. Selecting a sample is a fundamental element of a quantitative study. Stratified sampling was used to obtain the sample, which can be taken to be true for the whole population. The strata were identified based on country, age, gender, position type, and research discipline. To gather a substantial number of respondents, snowball sampling was pursued, which involved daily and routine distribution (social media and e-mail posting) of an introductory e-letter and survey-link requesting participation in the research. To increase response rates, the following methods were used: involving academics (encouraging colleagues), pushing the survey (providing respondents with the survey URL in e-mails sent directly to them), publishing the project with a link for the basic questionnaire on the ResearchGate website and Facebook fan pages and providing frequent reminders.1</p><p><strong>3. Data collection</strong></p><p>Based on several analyses showing that surveys conducted over the internet provide results that are as valid as more "traditional" methods and due to social distancing caused by the coronavirus pandemic, we used the Computer Assisted Web Interview (CAWI) method for recruiting respondents and collecting data. The LimeSurvey tool was employed for recruiting reliable samples. The data were collected during a two-month period of work, between June 11, 2020, and August 18, 2020. This led to 982 responses. After screening the responses and excluding outliers, 476 usable, correct, and complete responses were collected. This uploded dataset is a subset of a larger dataset that the authors collected for their research project titled "The Effects of the Coronavirus Pandemic on Scientific Research and University Teaching". It includes the questionnaire responses related to research during and after the COVID-19 pandemic. The questions were designed to gather information about the impact of the pandemic on academic scientists' research.1</p><p><strong>4. Results</strong></p><p>Our results may suggest targeted policies to alleviate the disruptions experienced by specific scientific fields. The findings of the past research were documented in three articles, which can be found below: </p><p>1. Ziemba, E. W., & Eisenbardt, M. (2022).

Research data and related information to the paper Asrat, Z. et al. 2023/24
<p>Many mountain-restricted animal species, including<i> Canis simensis, Tachyoryctes macrocephalus, Tragelaphus buxtoni, </i>and <i>Tragelaphus scriptus</i>, can be found in the Ericaceous vegetation of the Bale Mountains, which is a biodiversity hotspot (Miehe and Miehe, 1994; Girma et al. 2018). Currently it's under pressure from a rising human population, it is characterized by fire-resistant woody trees or branched shrubs of <i>Erica </i>(<i>Erica trimera</i> and <i>Erica arborea</i>) (Wesche et al., 2000; Gil-Romera et al., 2019). We postulate that the current change in the distribution of <i>Erica </i>plants is due to anthropogenic disturbances rather than seed scarcity, in addition to the <i>Erica </i>distribution edge. In order to determine their effects on the composition of Ericaceous vegetation and the regeneration of soil seed banks, we collected data considering aspects, altitude, and disturbance of the environment. Our data includes list of plant species and corresponding families' , including growth habits and lifestyle. We identified species from stand vegetation and germination test plots, and our data contained plant cover, families, and related abundance data to show the major environmental constraints on <i>Erica </i>growth above tree-line. Along with the vegetation data, we ranked anthropogenic disturbance by site observation, and the study plots floor covers, altitude, and aspect are included for testing variability. For every site, the density of <i>Erica </i>seeds and the <i>Erica </i>cover are arranged in columns and tested for significant factor. Pleas read the journal article for more information.</p>

Understanding Organizational Commitment and its Factors Influencing the Nurse's Job Satisfaction in Hospitals- A Systematic Literature Review and Further Research Agendas
<div> <p><em><span>Organizational commitment is a crucial concept when it comes to human resource management and Organizational behavior. It has to do with how much a worker commits to and identifies with the goals, values, and purposes of their company. Elevated levels of Organizational commitment are associated with enhanced job satisfaction, less attrition, and better performance. The expected ideal condition, status, and research deficit are all included in this article. A research agenda is determined by applying the ABCD framework to qualitatively analyze the identified research gap.The paper documents the topic and provides helpful information about it, which will aid future scholars. </span></em></p> </div>
Autonomous millimeter scale high throughput battery research system
<p>In this study, we present data from high-throughput cyclic voltammetry (CV) test, derived by our digital workflow, Auto-MISCHBARES, complemented by XPS analysis. This research is part of the pre-print publication named "Autonomous millimeter scale high throughput battery research system", showcasing Cathode Electrolyte Interphase (CEI) investigation. The electrolyte used for this experiment is 1M of LiPF6 solution in an Ethylene Carbonate (EC): Ethyl Methyl Carbonate (EMC) mixture with a 3:7 weight ratio, along with LFP as our electrode material. The CV tests were conducted through a high-throughput sequential process for two cycles, each with varying stop potentials. After the experimentation phase, XPS analysis was applied to characterize the synthesized CEI.</p>
