Seismic Monitoring of a Subarctic River: Seasonal Variations in Hydraulics, Sediment Transport, and Ice Dynamics

High‐latitude rivers are commonly covered by ice for up to one third of the year. Our understanding of the effects of ice on channel morphodynamics and bedload transport is hindered by the difficulties of sensing through the ice and dangers of field work on thin ice or during ice break‐up. To avoid this drawback, we used seismic signals to interpret processes and quantify water and sediment fluxes. Our objective was to determine seasonal differences in hydraulics and bedload sediment transport under ice‐covered versus open‐channel flow conditions using a small seismic network and to provide a first‐order estimation of sediment flux in a Fennoscandian river. Our study reach was on a straight, low‐gradient section of the Sävar River in northern Sweden. Interpretations of seismic signals, from a station 40 m away from the river, and inverted physical models of river stage and bedload flux indicate clear seasonal differences between ice‐covered and open‐channel flow conditions. Diurnal cycles in seismic signals reflecting turbulence and sediment transport are evident directly after ice break‐up. Analysis of seismic signals of ice‐cracking support our visual interpretation of ice break‐up timing and the main ice break‐up mechanism as thermal rather than mechanical. Assuming the bulk of sediment moves during ice break‐up and the snowmelt flood, we calculate a minimum annual sediment flux of 56.2 ± 0.7 t/km2, which drastically reduces the uncertainty from previous estimates (0–50 t/km2) that exclude ice‐covered or ice break‐up periods.
Coastal adaptation at Klasies River main site during MIS 5c-d (93,000–110,000 years ago) from a southern Cape perspective

Abstract Coastal adaptation in the southern Cape can be seen around 100,000 years ago in sites such as Klasies River, Blombos Cave, and Pinnacle Point, representing the occupation of a new niche by early Homo sapiens in this region. However, there is relatively little information available on the details involved in fully entering this niche from a regional perspective. At Klasies River main site (KRM), evidence for coastal adaptation occurs in early MIS 5. Here we explore the variability in shellfish exploitation and how it links to lithic technology, in deposits dating to ca. 93,000–110,000 years ago. We compare this to broadly contemporaneous assemblages from Pinnacle Point 13B and Blombos Cave. The lithics in all the layers from KRM investigated here have been produced according to a unidirectional reduction system, but the lowermost assemblages contain more small debitage and bladelets, and no tools. These 110 ka layers are associated with a lower shellfish density and more diverse range of shellfish species and a higher lithic density. This points to a lesser dependency on shellfish coinciding with higher mobility in the lower layers. For the younger MIS 5c layers higher volumes of shellfish and the dominance of certain species is evident. The lithics show that all the stages of the reduction system are present and tools are produced and used on-site. This indicates a residential (provisioning of place) occupational strategy. Compared to other sites on the southern Cape coast, KRM shows exceptionally high densities in lithic artifacts while the shellfish densities are comparable to the Blombos M3 phase. The results of the analysis of the shellfish and lithic densities, technological patterns, and shellfish species exploited at Klasies River, Blombos Cave and Pinnacle Point, demonstrate a more diverse onset and expression of coastal adaptation during early MIS 5 than apparent from current literature.

Mobility Acceptance Factors of an Automated Shuttle Bus Last-Mile Service

The main interest of this paper is to analyze the mobility acceptance factors of an automated shuttle bus last-mile service. There is limited research on the passengers’ perception of security and safety of automated mobility, whereas prior research is mostly based on surveys interested in attitudes towards self-driving vehicles, without being linked to the experience. We, on the other hand, are interested in passengers’ feeling of security and safety, after taking a ride with an automated shuttle in an open urban environment. For studying this, we conducted an automated shuttle bus last-mile pilot during a four-month period in the city of Tallinn in late 2019. The method is a case study focusing on one city with several tools for data collection applied (surveys, interviews, document analysis). The pilot, open and free for everybody, attracted approximately 4000 passengers, out of which 4% responded to the online feedback survey. For studying the operational capacity, we had a panel interview with operators of the shuttle service, in addition to analyzing daily operational log files. The results indicate that passengers’ perceived feeling of security and safety onboard was remarkably high, after taking a ride (and lower without a ride, in a different control group). The bus was operated only if operational capacity was secured, thus having significant downtime in service due to environment, technology and traffic-related factors.
How to improve new product performance through customer relationship management and product development management: evidence from China

Purpose This paper aims to investigate how to improve new product performance in turbulent circumstances of emerging economies. Design/methodology/approach This paper used regression analysis to examine the performance impact of customer relationship management (CRM) and product development management (PDM) concentration strategy in new product development (NPD). A detailed contingent analysis of the market and institutional environments in emerging economies is also conducted based on a survey of 114 Chinese high-tech manufacturers. Findings The research findings show that PDM has a stronger positive effect on new product performance than CRM in emerging economies and that the contingent effects of the market and institutional environment vary. More specifically, technological turbulence and enforcement inefficiency can positively moderate the relationship between CRM and new product performance, whereas the moderating effect of market turbulence on CRM is negative. Meanwhile, enforcement inefficiency negatively moderates the effect of PDM on new product performance, while the moderating effect of market turbulence on PDM is positive. Research limitations/implications This paper is limited to a survey of high-tech manufacturing enterprises in China. Further research should continues to explore and document the strategic issue about NPD in emerging economies by longitudinal study. Originality/value This paper contributed to theoretical and practical initiatives on the strategic issue of NPD and provided firms a further understanding of how to select the right NPD strategy in emerging economies to improve new product performance.
Ceramic studies and petrographic analysis in Levantine archaeology, the limitations of current approaches

By way of an introduction to this volume, we look to provide a brief review of recent approaches to ceramic studies in Levantine archaeology, and to the way that the results of laboratory-based investigations have been integrated within these. As we are interested in using ceramic data to address questions that extend beyond single-site studies, we pay particular attention to the information potential offered by the large-scale integration of ceramic and petrographic data from multiple archaeological projects. We will begin by highlighting some of the weaknesses of traditional approaches to pottery in Levantine archaeology and how these have continued to limit the interpretive potential of ceramic data. The strengths and weaknesses of petrographic research in the region to date will be discussed, and observations made regarding the use of petrography and geochemistry to address wider issues. The question of how new approaches, and the large-scale integration of ceramic data, might be used to address key social and economic questions in Levantine archaeology will form the subject of the concluding paper of this volume.
Bacterial colonization and antibiotic sensitivity pattern of in-born and out-born neonates in a tertiary care hospital of kolkata, india

Aims: To determine the spectrum of organisms with their sensitivity pattern and to explore whether the organisms isolated from inborn and outborn groups of neonates are identical or different. Methods: A total of 100 (50 inborn and 50 outborn) neonates were included in the study and 100 samples/swabs were taken from each site, viz axilla, umbilicus, groin, nose and stool at 6 hrs and 72 hrs. Individual swab sticks containing different samples were inoculated on blood agar as well as MacConkey agar media plates and incubated overnight at 37°C. Specific identification of individual organisms was carried out by an automated system. Results: From all the swab regions, common gram negative pathogenic organisms were Klebsiella sp. followed by Acinetobacter sp. , whereas, common gram positive pathogenic organisms were Staphylococcus aureus and undoubtful pathogen CONS. No statistically significant dissimilarities were observed among the nature of organisms isolated from inborn and outborn groups at 6 hrs and 72 hrs after admission. Similarly, the sensitivity patterns of the organisms isolated both from inborn and outborn babies were also identical. Conclusion: The similarities among the bacterial colonization and their sensitivity pattern seen in our study participants make us infer that there might be single ward for the care of inborn and outborn neonates. This possibly obviates the need for segregating the outborn neonates as bacteriological milieu is identical in both the groups. This in turn will reduce the cost and complexity of treatment.
Antifungal potentials of Luffa cylindrica (Roem) ethyl acetate leaf extract

Background: Plants remain as an untapped reservoir of potentially useful chemical compounds. Objectives: The objectives of this study were to evaluate the in vivo antifungal activities, bioautographic profile and in vitro mechanism of action. Methods: The in vivo antifungal activity was investigated against Candida albicans and Trichophyton rubrum in Wistar rats. Thin layer bioautographic profile of the ethyl acetate extract was assessed using agar overlay method. The possible in vitro mechanism of action of the crude ethyl acetate extract was assessed by the sorbitol protection assay and release of cellular materials assay. Results: The bioautographic profile showed the presence of three active spots having retardation factors of 0.4, 0.6 and 0.92 and diameter zone of inhibition, 15.0 – 30.0 mm. The in vivo antifungal (dermal) activity of the crude ethyl acetate extract, revealed a gradual healing of the infected rats skin upon treatment with the extract formulation, with no visible clinical signs of toxicity to the skin. In vivo systemic antifungal evaluation of the crude extract at a dose of 1500 mg/kg produced the strongest systemic antifungal activity with a total kill of all the fungal isolates at day 3 of treatment in rats however, histopathological examination after oral administration revealed signs of toxicity to vital organs (kidney, liver and lungs). Conclusion: The good in vivo activity supports its ethno-botanical use in the treatment of skin diseases.
Understanding the parkrun community; sacred Saturdays and organic solidarity of parkrunners

Abstract This article focuses on parkrun, the multi-site weekly timed 5 km run, which operates around the world. Using Durkheim’s work on community, we use qualitative data from a survey of over 8000 parkrunners to make sense of the parkrun community. We argue that parkrun allows for an organic solidarity that celebrates the various moral rationales for participation. We suggest that this organic solidarity produces a collective effervescence that enables parkrunners to think of themselves as part of something bigger than their sporting/health projects. Following Durkheim’s ambivalence, we argue that parkrun’s collective effervescence may be a double-edged sword. It may make a novel impact on public health by facilitating an increase in physical activity levels amongst previously inactive indviduals, yet it may also reinforce the exclusion of those who perceive themselves to be outsiders to the parkrun community.
Increased expression diversity buffers the loss of adaptive potential caused by reduction of genetic diversity in new unfavourable environments

Mechanisms underlying adaptation to rapid environmental change are issues in evolutionary biology. It is widely accepted that reduction in genetic diversity when suddenly exposed to an unfavourable environment limits the adaptive potential of populations. With growing empirical evidence that expression diversity is likely to increase in the new environment, the role that expression diversity plays in adaptation needs to be theorized. Here, we first established a negative exponential relationship between expression diversity and genetic diversity using a phenomenological differential equation. We then derived a complex trade-off relationship between the changes of expression and genetic diversity, which followed a combination of exponential functions. Furthermore, we found the increase in expression diversity could buffer the loss of adaptive potential as genetic diversity decreased to a certain extent. These theoretical deductions were validated by transcriptomic data of Miscanthus lutarioriparius grown in two experimental fields and supported by good fit and random simulation. These results suggest that increased expression diversity may compensate the loss of genetic diversity and allow the populations to maintain a certain level of phenotypic variation to cope with sudden environmental change. This may buffer the quick diminishing of adaptive potential and consequently increases the change of adaptation to the new environment.
Optimising effective parameters to improve performance quality in lateral flow immunoassay for detection of PBP2a in methicillin-resistant Staphylococcus aureus (MRSA)

Abstract Lateral flow immunoassay (LFIA) is the most widely used platform of the point-of-care (POC) detection. Since the most important factor in deciding the results of this technique is the visual quality of the test, it should be at its optimum. To address this issue, the present study examines optimising critical parameters to improve the quality of LFIA performance. In this regard the penicillin-binding protein 2a (PBP2a) in methicillin-resistant staphylococcus aureus (MRSA) was selected as a bacterial model. The targeted parameters included a) size of gold nanoparticles (AuNP), b) antibody conjugation conditions with AuNP, c) antibody concentrations in the capturing zones, d) the effects of blocking substances and different chemical buffers for pre-treatment of the strips. Visual quality of different manufactured strips revealed that the diameter of 14 ± 2, PH = 9.5 was the optimum for improvement of MRSA detection quality. The optimum concentration of labelling antibody in conjugate pad and concentration of the capturing antibody in the test band were 40 µg/ml and 1.1 µg/μl in PBS buffer (pH 7.4) respectively. In conclusion by finding the critical factors affecting the detection limit of lateral flow and optimising them, the visual quality of LFIA results can be increased.
Linking the vectorial capacity of multiple vectors to observed patterns of West Nile virus transmission

1. Theoretical models suggest that increased vector species participation in patho gen transmission significantly increases the prevalence of vector and host infec tions. However, there has been a lack of empirical evidence to support this. 2. We linked transmission potential of multiple vector species to observed patterns of enzootic pathogen transmission by conducting longitudinal field surveillance of West Nile virus (WNv) infections in Culex spp. mosquitoes and avian host com munities in the southeast U.S. We then used a temperature- dependent vectorial capacity model as a predictor of WNv infections in mosquitoes and birds using general linear mixed effects models. 3. Two WNv- competent Culex spp. mosquitoes were present in our study sites, Culex restuans Theobald during the spring and Culex quinquefasciatus Say during the summer . Empirical evidence of WNv transmission was limited exclusively to time periods when night time temperatures were suitable for accelerated within-
Contribution to the systematic knowledge of endemic Aubrieta pinardii Boiss. (Brassicaceae) from Turkey

The aim of this study was to document the taxonomical, morphological, anatomical, palynological and cytological characters, and geographical distribution of endemic Aubrieta pinardii Boiss. (Brassicaceae) from Turkey. The description of the taxon was revised as a consequence of comprehensive assessments of many specimens. The surface pictures belonging to seed and pollen of the taxon were obtained by Scanning Electron Microscope. The seed surface ornamentation was rugose. The pollen was radially and isopolar and prolate in forms, with polar axes of 19.52 ± 0.29 μm and equatorial axes of 13.04 ± 0.22 μm, with oval outlines in the equatorial axes, and elliptical in the polar axes. They were three–colpate and colpus sizes varied between 12.98 μm and 13.29 μm in length, and between 1.33 and 2.09 μm in width. Also, the anatomical structures of the root, stem and leaf of species were studied. In cytological studies, the chromosome number of species was found as 2n = 16 (x =8). This was the first work including taxonomical, morphological (macro and micro), anatomical and cytological data of endemic Aubrieta pinardi

Abstract Employment has been identified at the top of the list of young people’s concerns across Europe. Given the fact that in Bosnia and Herzegovina youth is one of the most vulnerable group, mainly due to the high unemployment rate, the main goal of this paper to determine the key individual and household characteristics of young people that influence their employment probability in order to support further development of decision-making policies in the labour market of Bosnia and Herzegovina. By using the USAID MEASURE-BiH National Youth Survey data set we analyse the effects of various individual and household characteristics on the probability of youth employment in Bosnia and Herzegovina. The analysis has revealed that education, age, gender and certain household characteristics have an impact on the probability of youth employment. The paper is expected to produce useful pieces of information that might be helpful for government decision-makers in Bosnia and Herzegovina in the process of creating employment policies to support young people.
A Review on Temperature-Dependent Electrochemical Properties, Aging, and Performance of Lithium-Ion Cells

Temperature heavily affects the behavior of any energy storage chemistries. In particular, lithium-ion batteries (LIBs) play a significant role in almost all storage application fields, including Electric Vehicles (EVs). Therefore, a full comprehension of the influence of the temperature on the key cell components and their governing equations is mandatory for the effective integration of LIBs into the application. If the battery is exposed to extreme thermal environments or the desired temperature cannot be maintained, the rates of chemical reactions and/or the mobility of the active species may change drastically. The alteration of properties of LIBs with temperature may create at best a performance problem and at worst a safety problem. Despite the presence of many reports on LIBs in the literature, their industrial realization has still been difficult, as the technologies developed in different labs have not been standardized yet. Thus, the field requires a systematic analysis of the effect of temperature on the critical properties of LIBs. In this paper, we report a comprehensive review of the effect of temperature on the properties of LIBs such as performance, cycle life, and safety. In addition, we focus on the alterations in resistances, energy losses, physicochemical properties, and aging mechanism when the temperature of LIBs are not under control.
Safety and feasibility of the Woven EndoBridge device deployment with monitored anesthesia care

Objective The Woven EndoBridge (WEB) device can be used for complex intracranial aneurysms (IAs), mostly under general anesthesia (GA). However, it remains controversial if anesthetic management could affect procedural outcomes after endovascular treatments using the WEB for IAs. The purpose of this study is to investigate the safety and feasibility of the WEB deployment for patients under monitored anesthesia care (MAC). Methods We reviewed 27 IAs in 25 patients who were treated by using the WEB device from February to December in 2019. Our first-line anesthetic management of patients during the procedures was the MAC. GA was performed based on patient’s clinical status or preference. Subjects’ demographic data, aneurysms’ characteristics, procedure-related complications, grade of stasis after the WEB deployment, duration of procedure, and length of hospital stay were compared between subjects who underwent GA versus those who underwent MAC. Results Successful deployment of the WEB device was obtained in all patients. In total, 10 and 17 IAs were treated with GA and MAC, respectively. There was no significant difference in demographics (age: p = 0.12, sex: p = 0.54), aneurysms’ characteristics (ruptured: p = 1.00, neck width: p = 0.96, aspect ratio: p = 0.98, maximum diameter: p = 0.69), complications (p = 1.00), postprocedural grade of stasis (p = 1.00), duration of the procedure (p = 0.23), and the length of hospital stay (p = 0.81) between GA and MAC. Conclusions MAC can be used for the WEB device deployment safely and effectively.
