Propriété des défauts lacunaires dans le carbure de silicium : évolution de leur nature en fonction des conditions d'irradiation et intéraction avec l'hélium

Le carbure de silicium est un des materiaux envisages pour des applications nucleaires tels que les reacteurs a fission de 4eme generation et les reacteurs a fusion. Dans ce cadre, le SiC serait soumis a des conditions extremes de temperatures et d’irradiation ainsi qu’a la presence de gaz issus des produits de fission ou d’activation qui necessitent de comprendre comment les proprietes physiques du SiC pourraient evoluer. Dans le present travail nous nous sommes attaches a etudier les phenomenes se deroulant a l’echelle atomique qui modifient la microstructure et peuvent degrader les proprietes macroscopiques. La premiere partie de cette these est consacree a la caracterisation de l’endommagement et notamment des defauts lacunaires crees dans le SiC par irradiation avec des ions lourds a differentes energies et differentes fluences au moyen de la spectroscopie d’annihilation de positons (PAS) complete par la spectrometrie Raman. Les resultats de cette etude mettent en evidence que l’importante perte d’energie electronique associee aux irradiations avec des ions lourds modifie la nature et la distribution des defauts en-dessous de 0.2 dpa. Au-dela, l’impact n’est pas visible. Pour un endommagement a fort dpa en regime de collisions elastiques, l’amorphisation peut etre atteinte. Elle se caracterise par la formation de volumes libres equivalents a l’hexalacune. La deuxieme partie est consacree a l’etude de l’interaction de l’helium avec les defauts lacunaires dans des echantillons de SiC implantes He 50 keV a deux fluences. La distribution des defauts lacunaires etudiee par PAS evolue avec la temperature et deux stades d’evolution majeurs ont ete mis en evidence, celui a plus haute temperature depend de la fluence. Des mesures de thermodesorption ont montre que le second stade coincidait avec la desorption de l’helium. Enfin, des mesures de RBS et NRA en mode canalisee ont permis de localiser l’helium dans la maille cristalline et d’observer qu’une fraction migrait en quittant des sites interstitiels tetraedriques a une temperature correspondante au premier stade.
Yield performance of oyster mushroom (Pleurotus ostreatus) on different substrate

Substrate type is an important factor determining growth and yield of oyster mushroom. Five different substrates namely rice straw, maize husks, banana leaves, fingermillet husk and mixture of rice straw and black gram pod shell (1:1) were evaluated for the yield and related attributes of Pleurotus ostreatus. Standard cultivation practice was followed with steam sterilization and spawning was done on 575 g of substrate in individual poly-bag. The data of three flushes were recorded. Our results revealed that full spawn run completed earlier (18.57 days) in fingermillet husk as compared to any other tested substrates. The highest total quantity yield was obtained in fingermillet husk (1024.57g/bag) and rice straw (956.14g/bag) with corresponding biological efficiency 178.19% and 166.29%, respectively which were significantly higher than all other treatments (Mandeel et al., 2005). The cropping duration was significantly higher in maize husks and banana leaves as compared to rest of three treatments viz., fingermillet husk, rice straw and mixture of rice straw and black gram pod shell (1:1). These three treatments were not statistically different for cropping duration with each other. Considering the biological efficiency and earliness of crop the performance of fingermillet husk, followed by rice straw was found to be better.
The Relative Influence of Total Reward on Retention of Human Resources

After reviewing the literature on the concept of total reward and human resource behaviour desired by organisations, this study suggests a model of total reward for retaining human resources in organisations grounded on the WorldatWork model of the research group at A&M Texas University (Boswell et al., 2011). Study participants were the employees, master and doctoral students from Iasi, Romania. The study was conducted to fi nd out the preferred organisational rewards among respondents in employment interviews (for attraction into organisations), and after employment (for retention into organisations). Also, the questions included in the questionnaire referred only to rewards practised in Romania, which are in compliance with the legislation on force. The designed questionnaire was pretested twice: in April and December of 2014 (Hodor, 2015), and was signifi cantly modifi ed. The study results show the fact that the variables that compose total reward – compensation (C), granted benefi ts (B), personal and professional life balance (WLB), performance and recognition (P & R), career opportunities and development (O & D) – become important after the moment of employment. Also, the study reveals that work-life-balance has the highest importance in human resources’ retention. Additionally, the presence of such rewards as remuneration, benefi ts, performance and recognition infl uences the decision to remain in the organization. In this paper are also presented other synthetic results of the entire study completed in 2017.
Cryopreservation of Cell Culture Derived from Dorsal Root Ganglia of Neonatal Pigs

The effect of cryopreservation with various concentrations of dimethyl sulfoxide (DMSO) on morphofunctional properties of the dorsal root ganglia cell culture (DRGCC) was investigated in this research. Cells were obtained from the dorsal root ganglia of neonatal piglets and cultured for 7 days in I±-MEM with 10% fetal calf serum (FCS). These conditions promote a predominant growth of satellite glial cells (SGCs). The resulting culture was cryopreserved at a rate of 0.5 deg / min to â€“20Â°C at stage 1, and at 1 deg / min to â€“80Â°C at stage 2, afterwards the samples were immersed into liquid nitrogen. Cryoprotective solutions based on I±-MEM, 25% FBS, and DMSO at final concentrations of 5, 7.5, and 10% were used. After warming on day 10 of subculturing, the cell viability, relative monolayer area, and glutamine synthetase expression as a marker of SGCs were evaluated. It has been established that cryopreservation of DRGCC using 7.5% DMSO provided 87.7% of viable cells after warming and 85% relative monolayer area in respect of an intact control. The amount of SGCs was about 95%. The obtained results allow us to recommend the chosen regimen for low temperature storage of cell cultures enriched with MG.

E-Consumers and Local Food Products: A Perspective for Developing Online Shopping for Local Goods in Poland

The constant development of consumer awareness regarding sustainable development has spread to food markets. Decisions related to food consumption are increasingly becoming, for consumers, an opportunity to demonstrate a specific value system, contesting mass and globally distributed food. Local products began to appreciate local produce, which is the opposite of mass production. Local food is gaining popularity, being perceived as healthier, unprocessed, and containing fewer preservative compounds, while also requiring fewer natural resources, leading to a lower environmental footprint. The phenomenon of shopping virtualization has also been growing in strength lately, especially among food consumers. Although Polish food e-commerce is still relatively undeveloped, online food sales have been the fastest growing category of Internet sales. According to experts, by 2026, nearly 40% of all products globally will be sold online. The main purpose of this article was to identify the behavior of Polish consumers shopping online for local food products and to identify barriers to purchase. Our findings were then used to determine development opportunities for this form of trade in relation to local food in the light of new legislative solutions currently in force in Poland. As part of the research procedure, an extensive literature review was carried out. In addition, some of the research findings were cited regarding consumer behavior in the local food market, conducted on a population of 1067 respondents. The study showed that Polish e-consumers of local products are usually aged 30–40, well-educated, and are in a good financial situation. Respondents pointed to high prices as the main barrier to buying local products via the Internet, a drawback which may be remedied to some extent by the recently adopted legislative solutions falling under the scope of what is termed in Poland as agricultural retail trade as well as by the promotion of short supply chains such as the Polska Smakuje initiative.
Towards simultaneous localization and mapping tolerant to sensors and software faults: Application to omnidirectional mobile robot

In the last few years, simultaneous localization and mapping became an important topic of research in the robotics community. This article proposes an approach for autonomous navigation of mobile robots in faulty situations. The main objective is to extend the fault tolerance strategy to simultaneous localization and mapping in presence of sensor faults or software faults in the data fusion process. Fault detection and isolation technique is performed based on duplication–comparison method and structured residuals. The proposed fault tolerance approach is based on the extended Kalman filter for simultaneous localization and mapping when an absolute localization sensor is available. The validation of the proposed approach and the extended Kalman filter for simultaneous localization and mapping algorithm is performed from experiments employing an omnidrive mobile robot, equipped with embedded sensors, namely: wheel encoders, gyroscope, two laser rangefinders and external sensor for the absolute position (indoor global positioning system). The obtained results demonstrate the effectiveness of the proposed approach where it was found that its fault tolerance performance is based essentially on the selected residuals and the values of the fault detection thresholds to be used for the fault detection and isolation.
Blindness in echolocating bats

Abstract Vision in echolocating bats works complementary to their echolocation signals and is especially important in long-range orientation. Contrary to previous predictions, we report here the first case of blindness and ocular anomalies in healthy adult echolocating bats. Two anomalous individuals of Carollia perspicillata, two Artibeus planirostris and one Artibeus lituratus were captured in highly human-modified areas (urban and agricultural). One C. perspicillata was totally blind exhibiting completely closed eyelids and the others presented strong corneal opacity in their right eye. Our finding brings new insights about the habitat perception in mammals and suggests an unreported ecological compensation of the sensory system in bats.
Prioritized Data Transmission Mechanism for IoT

This paper proposes a novel data prioritization and transmission mechanism to minimize the number of packets transmitted and reduce network overload using the constrained application protocol (CoAP) in resource-constrained networks. The proposed scheme adopts four classification parameters to classify and prioritize data from a sensor. With the packet prioritization scheme, the sensed data having the lowest priority is only delivered using the proposed keep-alive message notification to decrease the number of packets transmitted. The performance evaluation demonstrates that the proposed scheme shows the improvement of resource utilization in energy consumption, and bandwidth usage compared with the existing CoAP methods. Furthermore, the proposed scheme supports quality-of-service (QoS) per packet by differentiating transmission delays regarding priorities.
Varying the Preparation Guide and Group Discussion in a Classroom Analysis of Interteaching

Interteaching is a strategy that shifts the emphasis from passive student learning to active engagement through the use of preparation guides, small group discussions, clarifying lectures, and frequent testing. Several classroom studies have demonstrated that interteaching leads to better student comprehension and higher test scores. However, the specific strategies used in these studies vary slightly. The goal of the present study was to compare two different ways of implementing the preparation guide and group discussions to determine which method led to higher academic success. A group design was used in two sections of a psychology course over two semesters. One section experienced the standard interteaching method, where students completed the entire preparation guide prior to class and engaged in small group discussions during class. The second section was divided into two groups and each group was given half of the preparation guide to complete. Students, then, went through two rounds of group discussions: first, in a dyad with a member that completed the same portion of the preparation guide and then in a larger group with another dyad who completed the other portion of the preparation guide. Students in the second section scored more points on exam questions that came from their half of the preparation guide and they demonstrated less of a preference for interteaching than those who experienced the standard interteaching method. Results from this study indicate that instructors should have students read and complete the entire preparation guide to allow for more effective implementation of interteaching.
Effect of Biochar Application as a Soil Amendment on Growth and Yield of Sesame (Sesamumindicuml.)

The experiment was conducted to study the effect of biochar on growth and yield of sesame. In the experiment, the treatment consisted of three varieties, viz., V1 = BARI Til- 2, V2 = BARI Til-3 and V3 = BARI Til-4, and five levels of biocharviz. , B0= control (no biochar application), B1= 2 t ha-1, B2= 4 t ha-1, B3= 6 t ha-1 and B4= 8 t ha-1. The experiment was laid out in two factors randomized complete block design (RCBD) with three replications.Variety, application of different levels of biochar and their interaction showed statistically significant variation in plant height, number of leaves plant-1at 55 and 80 DAS and at harvest, capsules plant-1, seeds capsule-1, 1000-seed weight, seed yield, stover yield, biological yield and harvest index.The highest plant height (70.34, 110.95 and 109.84 cm at 55 and 80 DAS and at harvest respectively), number of leaves plant-1 (80.47, 116.70 and 94.54 at 55, 80 DAS and at harvest, respectively), number of branches plant-1 (3.60), capsules plant-1(80.47), number of seeds capsule-1(56.02),seed yield(1.07tha-1)andharvestindex(36.46%)were observed in the variety BARI Til-4 cultivated with the application of biochar @ 6 t ha-1 (V3*B3) and the lowest one was observed in variety BARI Til-2 with no biochar application (V1*B0). Biochar is effective for increasing growth and yield of sesame. Bangladesh Agron. J. 2019, 22(2): 113-127
A review of the technological developments for interlocking at level crossing

A Level Crossing remains as one of the highest risk assets within the railway system often depending on the unpredictable behaviour of road and footpath users. For this purpose, interlocking through automated safety systems remains a key area for investigation. Within Europe, 2015–2016, 469 accidents at crossings were recorded of which 288 lead to fatalities and 264 lead to injuries. The European Union’s Agency for Railways has reported that Level Crossing fatalities account for just under 28% of all railway fatalities. This paper identifies suitable obstacle detection technologies and their associated algorithms that can be used to support risk reduction and management of Level Crossings. Furthermore, assessment and decision methods are presented to support their application. Finally state of the art and synergistic opportunity of which a combination of obstacle detection sensors with intelligent decisions layers such as Deep Learning are discussed which can provide robust interlocking decisions for rail applications. The sensor fusion of video camera and RADAR is a promising solution for Level Crossings. By applying additional sensing techniques such as RADAR imaging, further capabilities are added to the system, which can lead to a more robust approach.
Strategic IT investment decision: BuyPro Health GPO

Morgan Kendrick, Vice President of Business Development and Patient Safety at BuyPro Health group purchasing organisation (GPO), contemplated his options regarding the IT infrastructure project he hoped to champion as he took his new position in January of 2017. BuyPro was a prominent Canadian healthcare GPO. Kendrick hoped to leverage BuyPro’s prominent industry position to promote adoption of global standards for procurement and service delivery purposes. In order for BuyPro to adopt global standards and use them as effectively as Kendrick wished, the company would need to invest substantially in upgrading internal systems to make them standards-ready. However, investment in the required systems upgrades would not directly facilitate negotiating for lower unit pricing on supplies purchased by member organisations. As he considered the future needs of the company and its industry, Morgan considered how best to promote his vision and build support for the necessary precursor investments.

A critical review of literature on “unplugged” pedagogies in K-12 computer science and computational thinking education

ABSTRACT Background and Context Computational thinking (CT) is considered as a valuable literacy for all students, and its inclusion in compulsory schooling could increase the numbers of underrepresented students who pursue computing-related careers. Computer Science Unplugged (CSU) had success in making computer science (CS) accessible to K–12 students in outreach settings. Such “unplugged” approaches have the potential to do the same in formal education. Objective This review considers how research findings on unplugged pedagogies might advance CS/CT education priorities, while highlighting areas of unknown and tension. Method We conducted a search in academic databases using terms +unplugged “computer science” and +unplugged CT, and related terms. Findings We synthesized our review with existing ones to inform the priorities of CS-for-all and CT development. We surfaced CSU’s limitations to broaden access for underrepresented students and suggested a remedy. We proposed 10 research questions that fill key gaps to support efforts that provide just access to quality CS/CT education.
Abnormal Sensorimotor Integration in Adults Who Stutter: A Behavioral Study by Adaptation of Delayed Auditory Feedback

Stuttering is a fluency disorder, partially alleviated during altered auditory feedback, suggesting abnormal sensorimotor integration in adults who stutter (AWS). As weighting of multiple integrating-information sources would be decided based on their reliabilities, the use of external (auditory feedback) and internal information (prediction of sensory consequences) could correlate with speech processing. We hypothesized that abnormal auditory-feedback processing in AWS could be related to decrease in internal processing precision. We used a perceptual-adaptation experiment of delayed auditory feedback (DAF) to verify the hypothesis. Seventeen AWS and 17 adults who do not stutter (ANS) were required to say “ah” and judge the simultaneity between their motor sensations and vocal sounds in each stimulus onset asynchrony (SOA) (0, 25, 50, 75, 100, 125, or 150 ms) after inducing adaptation of DAF (three conditions with 0-, 66-, or 133-ms delay). While no adaptation occurred during the 0 ms condition, perceptual change in simultaneity judgment (adaptation effect) occurred during the 66 and 133 ms conditions. The simultaneity judgments following exposure in each SOA were fitted to the psychometric function in each condition for the AWS and ANS groups. We calculated the μ (signifying the point of subjective simultaneity and adaptation-effect degree) and σ (signifying the detecting precision) of each function and analyzed them by parametric analyses. For the μ, participant groups and adaptation conditions showed a significant interaction; the adaptation effect was greater in the AWS than in the ANS group. Additionally, the μ and σ were only positively correlated in the AWS group. The point of subjective simultaneity for auditory delay by inducing DAF was higher in AWS than in ANS, indicating that perception of simultaneity in AWS was influenced by DAF to a greater extent. Moreover, the significant positive correlation between the μ and σ in AWS showed that the more imprecise the internal auditory processing, the more AWS relied on auditory feedback. It is suggested that the reliability of internal information differed within the AWS group, and AWS with reduced internal reliability appeared to compensate by relying to a great extent on auditory feedback information.
Calcareous defence structures of prey mediate the effects of predation and biotic resistance towards the tropics

The importance of biotic interactions in creating and maintaining diversity is expected to increase towards low latitudes. However, the way in which predation affects diversity can depend on how predators mediate competitive interactions and also on defensive traits of prey. Here, we assessed the role of physical defences of prey to escape predation and how the importance of predation on community structure and diversity changes across latitude.
Role of miR-2909 in Prostate Carcinogenesis

The biggest challenge in prostate cancer treatment is to understand the signaling mecha- nisms controlling disease progression. In this context, microRNAs assume huge importance and have recently become an attractive area of research. MicroRNAs are naturally occurring, single-stranded, small non-coding RNAs of 19–25 nucleotides that regulate gene expression. MicroRNAs function as oncogenes or tumor-suppressor genes, and their deregulation is a common feature of human cancers including prostate cancer. Among deregulated microRNAs in prostate cancer, some microRNAs are directly under androgen receptor signaling control and function as the effectors of androgen signaling. Recent findings have shown that apoptosis antagonizing transcription factor (AATF) gene encodes a microRNA designated as miR-2909 that plays an important role in prostate cancer progression. miR-2909 is identified as an androgen-regulated microRNA acting as a novel effector of androgen/androgen receptor signaling. It enhances the proliferation potential of prostate cancer cells and assists in prostate cancer survival under reduced androgen levels by maintaining a positive feedback loop with AR. miR-2909 exerts its oncogenic effects via multiple mechanisms including attenuation of tumor-suppressive effects of TGFβ signaling by directly targeting TGFBR2 and via STAT1 pathway and upregulation of ISGylation pathway through SOCS3/STAT1 pathway.
