Airborne survey of trace gases and aerosols over the Southern Baltic Sea: from clean marine boundary layer to shipping corridor effect

Abstract The influence of shipping on air quality over the Southern Baltic Sea was investigated by characterizing the horizontal and vertical distribution of aerosols and trace gases using airborne measurements in the summer of 2015. Generally, continental and anthropogenic emissions affected the vertical distribution of atmospheric pollutants, leading to pronounced stratification in and above the marine boundary layer and controlling the aerosol extinction. Marine traffic along the shipping corridor “Kadet Fairway” in the Arkona Basin is shown to influence the presence and properties of both trace gases and aerosol particles in the lowest atmospheric layer. Total particle number concentration and NOy mixing ratio increased in the corridor plumes, relative to background, by a factor 1.55 and 3.45, respectively. Titration, triggered by the enhanced presence of nitrogen compounds, led to a median ozone depletion of 19% in the corridor plumes. The enforcement of the Sulphur Emission Control Area (SECA) might be responsible for the minor sulphur dioxide increase (20%) in the corridor plumes. Ship traffic caused a minor enhancement of black carbon mass concentration, estimated to be around 10%. The study of individual ship plumes indicated that ship emitted aerosol was substantially different from background aerosol: fresh ship exhaust was preferentially enriched in aerosol particles with diameters below 100 nm and in black carbon particles with core diameters above 300-400 nm. With the present work the impact of marine traffic on the concentration and properties of atmospheric components within the marine boundary layer over the open water of the Southern Baltic Sea is assessed with airborne observations for the first time. Due to the high uncertainty affecting the estimations of ship emissions, this dataset represents a valuable reference for the assessment of ship emission inventories and related environmental-climatic impacts on the Southern Baltic Sea.
The impact of age, gender, acuteness and etiology on short-term clinical outcome in patients with subdural hematomas - international dual-center study

Introduction/Objective Subdural hematoma is one of the most common intracranial types of bleeding with high risk of disability and mortality. The aim of this study was to determine the influence of age, sex, acuteness, and etiology of subdural hematoma on short-term clinical outcome in these patients. Methods We retrospectively studied 288 patients who were diagnosed and operated on for subdural hematomas (SDH) with different etiology (traumatic and spontaneous) and acuteness (acute, subacute, and chronic) for a period of five years. Patients scored ≤ 5 points on the Glasgow Coma Scale at hospital admission were not included in this study. Clinical outcome was assessed by the modified Rankin Scale (mRS) score at hospital discharge. Descriptive statistics and logistic regression analysis were used to determine the effect of the investigated factors on short-term clinical outcome. Results Logistic regression analysis was conducted to predict degree of recovery (good = mRS ≤1 vs. poor = mRS ≥ 2 or death) using sex, age, acuteness, and etiology of SDH as predictive factors. It was established that the following three factors made a significant contribution to the outcome: age (p = 0.004), acuteness (p < 0.001), and etiology of a hematoma (p = 0.023), with acuteness being the strongest predictive factor. Sex was not a significant predictor, while age under 70 years and spontaneous origin of SDH were associated with lower mRS scores and had a positive effect on recovery chances. Conclusion Age, acuteness, and etiology of hematoma are important predictive factors that influence the short-term clinical outcome in patients with SDH. These parameters should be taken into account when giving prognosis for recovery chances to a patient’s family and relatives.
Structural Relationships among Teachers’ Goal Orientations for Teaching, Self-efficacy, Burnout, and Attitudes towards Teaching

Teachers’ goal orientations for teaching are one of the most important motivational beliefs affecting instructional processes. This study investigated the structural relationship between teachers’ goal orientations for teaching and their attitudes towards their job through measures of self-efficacy and burnout. 495 teachers (primary, secondary, or high schools) participated in the study. Hypothetical models were created and tested using the variables mentioned above. The results suggest: 1) mastery goal orientation, through self-efficacy and burnout measures, is a positive predictor of attitudes towards teaching, 2) work-avoidance orientation, through self-efficacy and burnout measures, is a negative predictor of attitudes towards teaching and 3) ability-approach orientation has no effect on attitudes towards teaching. In addition, it has been found that the above goal orientations do not have a direct effect on teachers’ attitudes towards teaching. The results are further discussed through comparisons to related literature.
Gallic acid liposome and powder gels improved wound healing in wistar rats

Aim: Gallic acid is an anti-inflammatory and antioxidant agent which could provide beneficial effects in preventing periodontal inflammation and improve wound healing. The present study aimed to evaluate the effects of gallic acid on experimental palatal wound model in Wistar rats. Material and Methods: 60 female Wistar rats were divided into three main study groups as the control group (C, n=24), gallic acid powder gel administered group (GP, n=18), and gallic acid liposome administered group (GL, n=18). Standardized palatal wounds of 5-mm diameter were created in all rats. Control rats received vehicle gel, and the other groups received either GP or GL gels. Control rats were sacrificed on days 0, 7, 14, and 21. GP and GL groups were sacrificed on days 7, 14, and 21. Hematoxylin-eosin staining was performed, and fibroblast cell counts and inflammatory cell infiltration in the wound area were evaluated. Transforming growth factor (TGF)-β expressions were determined via immunohistochemistry. Results: C, GP, and GL groups had a similar decrease in wound area apart from 21 st day, which GL had significantly lower wound area compared to the control group. Unhealed wound area was significantly lower on the 14 th and 21 st days in gallic acid groups. GP and GL groups had significantly higher fibroblast cell counts on all days compared to the C group. GL had significantly highest counts even compared to GP groups. Inflammatory cell infiltration was higher on the 7 th day compared to14th and 21st days in all groups. Gallic acid groups exhibited lower inflammatory cell counts on 7 th and 21 st days. TGF-β levels significantly increased in GP and GL groups on 7 th and 14 th days. Conclusion: Within limitations of the present study, it can be concluded that gallic acid in both powder and liposome forms increased fibroblast cell counts and decreased late inflammation along with increased TGF-β expressions in the wound healing process.
North-South diffusion of climate-mitigation technologies: the crowding-out effect on relocation

Abstract The deployment of cleaner production technologies is supposed to be crucial to mitigate the effect of climate change. The diffusion of technology from developed to developing countries can be done through different channels. It can be a business decision such as firms' relocation, opening of a subsidiary or the adoption of technology by southern firms, or it may be decided at the government level. This paper investigates, in a two-country model (North and South), the relationship between the diffusion of mitigation technologies, firms' relocation and the environment. We assume that both countries implement a carbon tax and there are two kinds of production technology used: a relatively clean technology and a dirty one. This paper theoretically shows that the technology diffusion by technology adoption, public transfer or subsidiary creation induces a decrease in relocation, while technology diffusion via purchasing dirty southern firms may increase the number of relocated firms. The paper also demonstrates that technology diffusion may have perverse effects in the long run. Indeed, total emissions may increase with technology diffusion since southern firms become more competitive.
Effect of 16 weeks diving practice at two different times of day on the pulmonary function, spirometry measurements and 6-minute walk test data of healthy professional Tunisian scuba divers

Abstract The aim of this study was to investigate the effect of time of the day (TOD) and 16 weeks diving practice (16WDP) on the spirometric parameters and 6-min walk test data (6MWT) on professional Tunisian scuba divers. In randomized order, 36 health males divided into 3 groups [morning practice group) (MPG): n = 12; evening practice group (EPG): n = 12; control group (CG) n = 12] participated voluntary in this study. They performed spirometry measurements and 6MWT during two periods: [before-season (June 05–10), and after-season (October 05–10)]. Our results revealed that assessment sessions comprised the following: FVC, FEV1, FEV1/FVC and PEF. Results were analyzed by applying repeated measures analysis of variance ANOVA. The spirometric parameters were similar upon two times of day on both EPG and MPG before the season (i.e. FEV1, FVC). Likewise, our finding revealed a significant decrease in lung functions following the 16 weeks practice of scuba diving upon two times of day. Thus, this period of hyperbaric scuba diving practice lead a significant alteration of lung function parameters with decrease of percent of variation in EPG vs. CEG compared to MPG vs. CMG: (i.e. FEV1, FVC, and PEF). In conclusion, 16 weeks of hyperbaric scuba diving lead a significant change in the spirometric and 6MWT values and respiratory problem with damage on lung function in healthy adult divers older than 40 years. Professional divers are recommended to have practice diving in the morning.
Usability Testing and the Development of an Augmented Reality Application for Laboratory Learning

In general chemistry laboratories, students learn practical laboratory skills through hands-on activities and are exposed to new scientific instruments. However, these instruments are often viewed as black boxes for various reasons, where students do not know how to use them or what the instruments are capable of. This tendency is likely to induce some measure of fear in the students’ attitude toward learning about instruments, even though instrumentation is a significant part of laboratory education. Augmented reality in educational laboratory (ARiEL) is an application utilizing AR technology designed to connect students to information on scientific instruments. ARiEL can be downloaded and used on phones or tablets while students are working on experiments, providing them with direct and immediate forms of information about laboratory instruments. Currently, the pH meter and conductivity meter are two instruments ARiEL can recognize as they are small, benchtop devices often used in general chemistry laboratory courses. An initial usability study with a focus group of first-term general chemistry students indicated that the application is not only easy to use but also preferred over a common search engine when looking for information on specific instruments. The application was used in a second-term general chemistry laboratory course and tested for usability evaluation and to measure students’ attitude toward chemistry instrumentation. The results suggest that the availability of ARiEL helps to reduce anxiety associated with using instruments and to improve intellectual accessibility.
Reconfigurable WPT system for load‐independent CC and CV output with transmitting‐side control

This study proposes a reconfigurable wireless charging topology, which achieves load-independent constant current (CC) and constant voltage (CV) output without any communication link between transmitting and receiving coils. The proposed topology is suitable for CC–CV modes of battery charging. Inductor (L), capacitor (C) and inductor (L) connected as T type (LCL) compensation with an auxiliary capacitor on the transmitting side and series (S) compensation on the receiving side (LCL-S) is used to achieve load-independent CC and CV output. Reconfiguration has been achieved using single AC switch on transmitting side. Control has been implemented with the information on transmitting side. Load-independent CC and CV output operations have been analysed analytically. The merits of the proposed topology are fixed-frequency operation, simplified control scheme for load-independent CC–CV operation without any communication link. Feasibility of the proposed topology is verified by the experimental prototype with a CC output of 12 A and CV output of 56 V.
The significance of microRNA genes expression in ovarian cancer cell lines resistant to cytotoxic drugs

Ovarian cancer is the most fatal type of gynecological cancer. The main reason for high mortality is the development of drug resistance. It can be related to increased expression of drug transporters and increased expression of extracellular matrix (ECM) proteins. miRNA is a short noncoding RNA that regulates expression of about 60% of genes in the human genome and plays a crucial role in developing cancer, including resistance to chemotherapy. Our foremost aim was to exhibit alterations in the miRNA expression levels in the cisplatin (CIS), paclitaxel (PAC), doxorubicin (DOX), and topotecan (TOP) - resistant variants of W1 sensitive ovarian cancer cell line using miRNA microarray. The second goal was to identify miRNAs responsible for the regulation of drug-resistant genes. According to our observation, alterations in the expression of 40 miRNA genes. The level of expression of 21 genes was upregulated in at least one drug-resistant cell line. The expression of 19 genes was downregulated in at least one drug-resistant cell line. We identified target genes for 22 miRNAs. Target analysis showed that miRNA regulates key genes responsible for drug resistance. Among others, we observed regulation of the ABCB1 (MDR1) gene in the W1PR1 cell line by miR-363 and regulation of the COL3A1 gene in the W1TR cell line by miR-29a. Hence, on the basis of our findings, results indicate that genes responsible for drug resistance development in ovarian cancer can be regulated by miRNA.

Temporal Effects of Catalase Overexpression on Healing Following Myocardial Infarction Running Title: Pendergrass et al: Inducible Catalase Overexpression and Infarction

Background Reactive oxygen species, such as hydrogen peroxide (H2O2), contribute to progression of dysfunction following myocardial infarction (MI). However, chronic overexpression studies do not agree with acute protein delivery studies. The purpose of the present study was to assess the temporal role of cardiomyocyte-derived H2O2 scavenging on cardiac function after infarction using an inducible system. Methods and Results We developed a tamoxifen-inducible, cardiomyocyte-specific catalase overexpressing mouse. Catalase overexpression was induced either 5 days pre or post-MI. Mice exhibited a 3-fold increase in cardiac catalase activity that was associated with a significant decrease in H2O2 levels at both 7 and 21 days. However, cardiac function improved only at the later time point. Pro-inflammatory and fibrotic genes were acutely upregulated after MI, but catalase overexpression abolished the increase, despite no acute change in function. This led to reduced overall scar formation, with lower levels of Collagen 1A and increased contractile Collagen 3A expression at 21 days. Conclusions In contrast to prior studies, there were no acute functional improvements with physiological catalase overexpression prior to MI. Scavenging of H2O2 however, reduced proinflammatory cytokines and altered cardiac collagen isoforms, associated with an improvement in cardiac function after 21 days. Our results suggest that sustained H2O2 levels, rather than acute levels immediately following MI, may be critical in directing remodeling and cardiac function at later time points.
3.4/4.0 GHz Tunable Resonant Cavity in SIW Technology Using Metal Post and PIN Diode on a Low-Cost Biasing Network for 5G Applications

This paper presents a dual-band resonant cavity in Substrate Integrated Waveguide (SIW) technology to operate in the range from 3.3 GHz to 4.2 GHz, spectrum considered for the Fifth Generation (5G) network. The cavity was designed to operate at 3.4 GHz and 4.0 GHz. To achieve different states, a jumper and a PIN diode switch are considered as switching elements, connecting and disconnecting the bottom and the upper walls of the SIW resonant cavity through a metal post inserted inside its internal volume. A fitting equation is proposed to predict the maximum resonance frequency caused by the insertion of a single metal post inside the internal volume of the SIW resonant cavity and a new low-cost biasing network is designed on a thin dielectric substrate allocated on the upper wall of the SIW resonant cavity, using transmissions lines and a single capacitor, reducing the final cost and the insertion losses. Good agreement was observed among the fitting equation, computational electromagnetic simulations, and experimental results, validating the proposed methods.
