Reconstructing Tonian seawater 87 Sr/ 86 Sr using calcite microspar

The Tonian Period follows a long interval of relative stasis and leads into the climatic extremes and biological radiations of multicellular life during the Cryogenian and Ediacaran periods, respectively. However, despite its pivotal situation, it remains relatively understudied, in large part due to the lack of robust age constraints. A combination of fossil evidence, radiometric ages and isotopic constraints reveal that carbonate strata on the North China craton (NCC) were deposited between c.980 and c.920 Ma, thereby filling a gap in marine archives. Here we present 87 Sr/ 86 Sr data from selected calcite microspar cements (CMC), which filled early diagenetic ‘molar tooth’ cracks, along with data from demonstrably well-preserved bulk carbonate samples. These new data show that seawater 87 Sr/ 87 Sr rose in stages from ~0.7052 at c.980 Ma to ~0.7063 by c.920 Ma, after which a return to low values coincided with the eruption of the Dashigou large igneous province (LIP) across the NCC. We also present a new Neoproterozoic seawater 87 Sr/ 86 Sr curve, which reveals that the general trend towards higher 87 Sr/ 87 Sr during the Tonian Period was checked repeatedly by the input of less radiogenic strontium from a series of eruptive events, both coincident with and prior to the main breakup of Rodinia. The weathering of Tonian volcanic provinces has been linked to higher carbon burial, glaciation and oxygenation due to the high phosphorus content of flood basalts. Here we show that the weathering of major volcanic provinces affected material fluxes and ocean chemistry much earlier than previously envisaged.
Adolescents’ Subjective Views about Interprofessional Team Participation: A Q-methodological Study

Background: One common arrangement in the Norwegian child welfare system is the interprofessional collaborating team, not unlike the English core group. This team is often referred to as the ‘responsible team’ (RT) and is arranged when a child has needs that call for several services. Few studies about interprofessional collaboration focus on views of service users and, in particular, those of child and adolescent service users. Aims and objectives: The present study aims to explore adolescents’ subjective views about their participation in RTs. This study contributes further knowledge about the field of interprofessional collaboration, especially regarding the participation of adolescents. Design: Non-experimental, exploratory research design. Methods: Q-methodology was used to explore 26 adolescents’ subjective views about their collaboration within the responsible teams that were formed to support their welfare. Q-methodology is known as being particularly suitable for revealing vulnerable people’s nuanced subjective views and perspectives. The adolescents in this study were asked to rank order a set of 42 statements (Q-set). PQMethod was used to analyse the data. Results: Four factors emerged and revealed patterns of shared views among the adolescents. Factor 1: Optimistic and engaged despite bad experiences , Factor 2: Strive to not be defeated by their helpers , Factor 3: Battle weary and resigned, and Factor 4: Content, positive and full of trust . Implications: The present study may be relevant to researchers, health and social policy makers, in addition to professionals working in services that aim to improve children’s situations through interprofessional collaboration.
Olfactory ensheathing cell transplantation for a patient with chronic sciatic nerve injury

Objective: To observe the result of olfactory ensheathing cell (OEC) transplantation in a patient with chronic sciatic nerve injury. Case report: A 53-year-old male patient with chronic (1 year) sciatic nerve injury on left side received OEC transplantation at the lesion site. He received follow-up assessment according to the American Spinal Injury Association standard at 10 days, 6 months, and 1 year after OEC therapy. The muscle strength of his left lower limb increased and numbness decreased during the early stage of cell therapy. His motor function improved with each evaluation. His limp walking gait recovered, and numbness sensation got nearly normal after 1 year of follow-up. There were no side effects. Conclusion: OEC transplantation may be an option for chronic peripheral (sciatic) nerve injury.
The Effect of Extract from Dill
 Anethum Graveolens
 on the Growth Performance, Body Composition, Immune System, and Antioxidant System of Rainbow Trout

In recent years, supplementing herbal medicines to fish diets in the aquaculture industry as a growth stimulant and immunostimulant is a common practice. In the present study, we investigated the effect of hydroalcoholic extract of dill on the growth performance and body composition of Rainbow Trout Oncorhynchus mykiss and its inhibitory effect against Aeromonas hydrophila in vitro. We also evaluated the immune responses and antioxidant system in fish that were fed dill diets over a period of 56 d. For this purpose, 180 Rainbow Trout fingerlings (initial weight 13.30 ± 0.22 g; mean ± SD) were purchased and they were fed four experimental treatments, which included a control diet and diets that were supplemented with 1Dill (1 g/kg dill extract), 1.5Dill (1.5 g/kg dill extract), or 3Dill (3 g/kg dill extract). According to the results, the fish that were fed 1Dill (54.70 g) and 1.5Dill (53.19 g) diets had significantly higher weight gain, although the feed conversion ratio was not significantly different among groups. However, the fish that were fed the 1.5Dill (62.55%) diet had significantly higher protein contents in the body than those that were fed the 3Dill (60.09%) treatment; the fish that were fed the 3Dill (29.00%) diet had higher lipid content than those that were fed the other diets. Regarding immune and antioxidant systems, the Rainbow Trout that were fed the 1.5Dill diet had significantly higher values of lysozyme in their serum (53.33 U/mL ), alternative complement pathway hemolytic activity (146.33 U/mL ), superoxide dismutase (52.33 U/mg protein), and catalase activity (164.66 U/mg protein) than the others did. Dill extracts in different dosages had no inhibitory effect against A. hydrophila in vitro. In summary, it can be concluded that the 1.5Dill diet can be used as a natural stimulant of growth, immunity, and the antioxidant system in the aquaculture industry.
The effects of gamified flipped instruction on learner performance and need satisfaction

Purpose This study aims to assess students’ learning performance and perceived need satisfaction between a gamified flipped classroom (GFC) and flipped classroom (FC) instruction in a low-tech setting. The iSpring Learn learning management system was used as a low-tech gamification application in gamifying the flipped learning class. Design/methodology/approach A quantitative research approach was used for collecting the data. Three formative assessments were used to examine students’ learning performance during the intervention period, and a post-questionnaire survey was used to support the data collection process with regard to students’ perceived needs satisfaction. In total, 56 students were involved in a non-randomised experiment with a control group design. Findings The results reveal that Assessment 1 showed no significant difference between the two intervention groups (p > 0.05), while Assessments 2 and 3 were significantly different (p < 0.05). The survey results confirm that participants in the GFC have achieved a great level of motivation because their innate psychological needs for competence, autonomy and relatedness are satisfied. Practical implications The use of game-like features can be a powerful means to produce more engaging and fun activities in the FC context. The study has confirmed that integrating the gamification concept into FC instruction by adding challenges, incentives, points and rewards to quiz questions promoted a more engaging and enjoyable experience for learners. Originality/value Gamification as a current concept of a twenty-first-century instructional skill has proven to be remarkably influential. This study suggests that the FC and gamification concept might be possibly implemented in a low-tech information environment – without the required advanced technology platform.
Identification of new sources of resistance to stem rust race Ug99 (TTKSK) in wheat genotypes

Stem rust disease which caused by Puccinia graminis f. sp. tritici is one of the major wheat production constraints in the high lands of central, south eastern and north western part of Ethiopia. The disease had caused up to 100% yield loss on the unprotected wheat farms. This study was conducted to identify new sources of resistance to stem rust disease. After the removal of genotypes that showed a major gene (race specific) resistance expression at seedling test, 60 selected genotypes were evaluated for their adult plant resistance to stem rust and agronomic traits across three locations (Debrezeit, Adet and Kulmsa) using a 5 × 12 alpha lattice design with three replications. Genotypes showed a highly significant difference (p = 0.001) on the traits of final rust severity (FRS), area under disease progress curve (AUDPC), coefficient of infection (CI) and apparent infection rate (r) at different locations. Moreover, combined analysis of variance also showed the presence of highly significant effects of genotypes, environments and GE interaction on the magnitude of FRS, AUDPC, CI, r, days to maturity (DM), plant height (PH), hectoliter weight (HLW), thousands kernel weigh (TKW) and grain yield (GY) across testing locations. The correlation analysis revealed the presence of positive highly significant (p<0.001) relationship of FRS with both CI (r=0.894) and AUDPC (r=0.877). A positive and highly significant (p<0.001) correlation was also observed between CI and AUDPC (r=0.996) of the tested genotypes. Principal component analysis indicated that only the first four principal components (PCs) explained 86.58% of the total variation among the tested genotypes. Cluster analysis also confirmed the presence of variation among the tested genotypes by dividing them into five major groups. In this study, four bread wheat genotypes (G12, G60, G31 and G52) were found to be resistant to stem rust disease across the three locations and could be used as source of stem rust resistance in future wheat improvement program.
Geographic variation in performance of a widespread generalist insect herbivore

1. Generalist herbivores are often widespread and occur in a variety of environments. Due to their broad distribution, it is likely that some populations of generalists will encounter host plants with geographic variation in traits that could affect the herbivore's growth and survival (i.e. performance). However, the geographic pattern of performance has rarely been studied for generalists, especially across large geographic ranges.
Study of Galactic Cosmic-Ray Flux Modulation by Interplanetary Plasma Structures for the Evaluation of Space Instrument Performance and Space Weather Science Investigations

The role of high-energy particles in limiting the performance of on-board instruments was studied for the European Space Agency (ESA) Laser Interferometer Space Antenna (LISA) Pathfinder (LPF) and ESA/National Astronautics and Space Administration Solar Orbiter missions. Particle detectors (PD) placed on board the LPF spacecraft allowed for testing the reliability of pre-launch predictions of galactic cosmic-ray (GCR) energy spectra and for studying the modulation of proton and helium overall flux above 70 MeV n − 1 on a day-by-day basis. GCR flux variations up to approximately 15% in less than a month were observed with LPF orbiting around the Lagrange point L1 between 2016 and 2017. These variations appeared barely detected or undetected in neutron monitors. In this work the LPF data and contemporaneous observations carried out with the magnetic spectrometer AMS-02 experiment are considered to show the effects of GCR flux short-term variations with respect to monthly averaged measurements. Moreover, it is shown that subsequent large-scale interplanetary structures cause a continuous modulation of GCR fluxes. As a result, small Forbush decreases cannot be considered good proxies for the transit of interplanetary coronal mass ejections and for geomagnetic storm forecasting.
Healthcare practitioner perspectives and experiences regarding vascular access device data: An exploratory study

ABSTRACT Background: A vascular access registry is a key strategy proposed to improve patient safety and quality, but its impact will be shaped by the attitudes, experience and resources of end-user stakeholders. This study aimed to examine stakeholders’ perspectives and experiences regarding the feasibility and utility of a standardized platform to collect vascular access data and to identify potential barriers and facilitators of a vascular access clinical quality registry. Methods: Individual (n = 17) and group (n = 1) semi-structured interviews were conducted between October–December 2018 with directors from various healthcare disciplines and policy makers in Australian healthcare facilities. Interviews were recorded, transcribed and analysed using inductive thematic analysis. Results: Overall, participants supported the idea of a standardized platform to capture vascular access data. Three main themes were identified: (1) data challenges (sub themes: standardized data capture, data quality and data sharing); (2) staff capability (lack of resources and feeling unsupported); and (3) logistics (resource capacity and implementation challenges). Conclusion: Stakeholder engagement and universal agreement on standardized vocabulary and data items are vital to registry development, implementation and sustainability. Continuous iterative cycles will be required to reflect upon, review and improve the processes around vascular access data collection using a standardized registry software platform.
Mathematical Modeling and Position-Sensorless Algorithm for Stator-Side Field-Oriented Control of Rotor-Tied DFIG in Rotor Flux Reference Frame

The rotor-tied doubly fed induction generator (DFIG) configuration has the advantages of higher efficiency and reduced size as compared to stator-tied DFIG for the same power rating. This article presents a mathematical modeling of rotor-tied DFIG in rotor-flux reference frame considering the observer at stationary reference frame. Furthermore, position-sensorless algorithm for the rotor-tied DFIG is proposed to estimate the rotor position, which is based on simple algebraic equations. The proposed position-sensorless algorithm is independent of critical machine parameters which makes the algorithm robust against parameter variations. The algorithm works accurately for different wind speed conditions and thus, useful for wind energy conversion system (WECS) which necessitates the constant frequency operation against variable wind speed. The effectiveness of the proposed position-sensorless algorithm is verified using hardware-in-loop (HIL) set up. OPAL-RT and STM32F407VG micro controller are used in the HIL. Simulation and experimental results for a 250 kW rotor-tied DFIG-based WECS are shown under different wind speed conditions.
Perceptions of Diversity Management Practices among First- versus Second-generation Migrants

Drawing on an extended case method approach consisting of observations, analysis of organisational documents and semi-structured in-depth interviews with first- and second-generation migrants working in a French car manufacturing company, this article examines how and why diversity management practices are perceived differently by first- versus second-generation migrant workers. Using social identity theory and equity theory as a theoretical framework, it was found that first- and second-generation migrants have different social expectations, which, in turn, influence their self-image, as well as their perception of organisational justice. The interaction between their social identity and their perception of justice affects how they appraise diversity management practices in their organisation. The study extends previous research on migrant workers and diversity management by building a conceptual model that outlines how and why diversity management practices are perceived differently by first- versus second-generation migrants.
CHANGES LN POSTURAL SWAY RELATED TO FATIGUE

The purpose of the present study is to investigate the influence on postural sway of such condition as fatigue resulting from muscular work. Twelve of the male adults (26.7•}6.2 yrs old) of a certain airport ground service company were served as the experimental subjects. The measurement of postural sway has been made by measuring the weight at two points of the supporting platform. The degree of postural sway was calculated by using an electronic computer (HITAC-10). The measurement was carried out before and after the work on each day during the experimental days. The following results were obtained. On the 1st day with eyes open the ratio of the postural sway after the work to that of before the work ('after'/'before') was 1.25, with eyes closed 113, respectively. On the 2nd day with eyes open it was 1.38, with eyes closed 1.53, respectively. On the last day with eyes open it was 147, with eyes closed 1.23, respectively. The amount of postural sway after the work was greater as compared with that of before the work. The statistical analysis showed that these difference in postural sway was significant(P< 0.05-0.001). The influence of several factors on the changes in postural sway was discussed, together with the experimental results obtained by other authors. In conclusion, these results suggest that balance impairment is mainly due to work-related fatigue. (J. Physical Fitness Japan 1979, 28 : 18-24)
Chromatin Dynamics Regulate Transcriptional Homeostasis

Eukaryotic promoters are inherently bidirectional and allow RNA Polymerase II to transcribe both coding and noncoding RNAs. Dynamic disassembly and reassembly is a prominent feature of nucleosomes around eukaryotic promoters. While H3K56 acetylation (H3K56Ac) enhances turnover events of these promoter-proximal nucleosomes, the chromatin remodeler INO80C ensures their proper positioning. In my dissertation, I explore how chromatin dynamics regulate transcriptional homeostasis. In the first part, I investigate the role of H3K56Ac on the nascent transcriptome throughout the eukaryotic cell cycle. I find that H3K56Ac is a global, positive regulator for coding and noncoding transcription by promoting both initiation and elongation/termination. On the contrary, I find that H3K56Ac represses promiscuous transcription following replication fork passage by ensuring efficient nucleosome assembly during S-phase. In addition, I show that there is a stepwise increase in transcription in the S-G2 transition, and this response to gene dosage imbalance does not require H3K56Ac. This study clearly shows that a single histone modification, H3K56Ac can exert both positive and negative effects on transcription at different cell cycle stages. In the second part, I investigate the role of the chromatin remodeler INO80C on the nascent transcription around replication origins. I show that INO80C, together with the transcription factor Mot1, prevents cryptic transcription around yeast replication origins, and the loss of these proteins lead to an increase in DNA double strand breaks. I hypothesize that recruitment of INO80C ensures proper positioning of nucleosomes around origins and the exclusion
Comparative phylogeography of two free‐living cosmopolitan cyanobacteria: Insights on biogeographic and latitudinal distribution

Free‐living bacteria have long been assumed to have little biogeographic signature because of their high potential for passive dispersal. Raphidiopsis raciborskii and Microcystis aeruginosa are free‐living cosmopolitan cyanobacteria with a probable tropical origin, that frequently form toxic blooms and are considered invasive species in middle latitudes. Despite these similarities, their phylogeographic patterns have seldom been directly compared. Our aim was to reconstruct the phylogeographic histories of R. raciborskii and M. aeruginosa, in order to explore whether their current distributions could be attributed to the same biogeographic events.

Pengaruh Model Pembelajaran Problem Based Instruction Berbasis Collaboration, Communication, Creativity and Critical Thinking Terhadap Hasil Belajar Rangkaian Elektonika

4C (Collaboration, Communication, Creativity and Critical Thinking) skill-based Problem Based Instruction (PBI) is student-centered learning so that it can do problem solving activities and make students think more critically, present creative ideas and communicate with the lesson more broadly. The learning model is a planning guide in determining the set of lessons in the classroom. Learning on students is still centered on the teacher or conventional so it does not provide opportunities for students to express ideas as if students think in communication, collaboration, creative and critical thinking. This study aims to determine the effect of the 4C Skill-based Problem Based Instruction learning model on electronic learning outcomes. The 4C skill-based PBI learning model uses a quasy type of experimental research. In this study the effect of the treatment (treatment) was analyzed by different tests, namely the group received different treatment, namely the experimental group PBI learning based on 4C skills and the control group with conventional learning (two groups). From the results of the study showed an increase in the average value of learning outcomes of the experimental class was higher than the increase in the average value of the control class. It can be concluded that the learning outcomes of students who use the 4C-based problem based instruction learning model are better than students who use conventional learning.
