Evaluation of port workers’ general awareness of dangerous cargo transport

The International Maritime Dangerous Goods (IMDG) Code training is mandatory for all shore-side personnel involved in the handling and transport of dangerous cargoes by sea. This study aims to measure and evaluate the port workers’ dangerous cargo transport general awareness level. For this purpose, the “Dangerous Cargo Transport General Awareness Questionnaire” was developed and applied to trained 100 port workers face-to-face. The questionnaire was proven to be valid and reliable by content validity, construct validity, internal consistency reliability, and test-retest reliability analyses. Four factors were determined as a result of Explanatory Factor Analysis. Discriminant analyses were performed using the Student’s t-test and One Way ANOVA test. Pearson correlation analysis was carried out to determine the relationship between factors. Simple linear regression analysis was used for modeling the relationship between factors. SPSS 24.0 was utilized to conduct the analyses. According to analysis results, port workers’ dangerous cargo transport general awareness does not differ depending on age, position, and education. There is a weak positive or a moderate positive correlation between factors. Port workers have an average and above-average level of general awareness. It is highlighted that increasing this level is possible by increasing the frequency of dangerous cargo transport training. Suggestions are offered for more effective training.
Local damage simulations of printed circuit boards based on in‐plane cohesive zone parameters

Purpose – The purpose of this paper is to analyse, in a finite element simulation, the failure of a multilayer printed circuit board (PCB), exposed to an impact load, to better evaluate the reliability and lifetime. Thereby the focus was set on failures in the outermost epoxy layer.Design/methodology/approach – The fracture behaviour of the affected material was characterized. The parameters of a cohesive zone law were determined by performing a double cantilever beam test and a corresponding simulation. The cohesive zone law was used in an enriched finite element local simulation model to predict the crack initiation and crack propagation. Using the determined location of the initial crack, the energy release rate at the crack tip was calculated, allowing an evaluation of the local loading situation.Findings – A good concurrence between the simulated and the experimentally observed failure pattern was observed. Calculating the energy release rate of two example PCBs, the significant influence of the chos.
Electrical properties and radiation hardness of SOI systems with multilayer buried dielectric

In this work SOI structures with buried SiO/sub 2/-Si/sub 3/N/sub 4/-SiO/sub 2/ layers have been fabricated by the ZMR-technique with the aim of improving the total dose radiation hardness of the buried dielectric layer. To optimize the fabrication process, buried layers were investigated by secondary ion mass spectrometry before and after the ZMR process, and the obtained results were compared with electrical measurements. It is shown that optimization of the preparation processes of the initial buried dielectric layers provides ZMR SOI structures with multilayer buried isolation, which are of high quality for both Si film interfaces. Particular attention is paid to the investigation of radiation-induced charge trapping in buried insulators. Buried isolation structures with a nitride layer exhibit significant reduction of radiation-induced positive charge as compared to classical buried SiO/sub 2/ layers produced by either the ZMR or the SIMOX technique.
Low field MRI with magnetoresistive mixed sensors

Low-field magnetic resonance imaging (MRI) requires very sensitive magnetometers for detection of weak magnetic signals in femtoTesla range. Magnetoresistive mixed sensors could be used as the sensitive magnetometers [1]. These sensors are the combination of a Giant Magnetoresistive (GMR) field sensor and a superconducting loop used as a flux-to-field transformer. A MRI set-up based on mixed sensor has been mounted. This system operates in static field up to 10mT without shielded room. We will present the LF-MRI setup with the implementation of mixed sensors and the first MRI images obtained at low field without prepolarization.
An exploration of midwives' views of the latest World Health Organization labour care guide

Effective labour monitoring is integral to intrapartum care. Yet, to date, tools to facilitate this have not reached their potential. This study aims to explore midwives' initial reactions to the latest World Health Organization labour care guide, which is a replacement to the existing partograph, to enable adaptations to be made and to inform implementation strategies. This was a qualitative study that used interviews and focus groups to gather data from a convenience sample of midwife delegates from six sub-Saharan Africa countries who were attending a midwifery conference in Malawi. Data were analysed thematically. A total of 43 participants participated; six focus groups and 12 individual interviews were conducted. Participants expressed both positive and negative views of the guide. Three main themes were found. The theme ‘sticking to what is familiar’ demonstrated reluctance to change; ‘chart based on usual or optimum practice’ suggested that midwives wanted a chart that reflects the routine care provided as opposed to the evidence-based care they should provide; and ‘measures for effective implementation’ highlighted the importance of having carefully considered and robust strategies for implementing the guide. This rapid evaluation provided a snapshot of midwives' initial reactions to the new labour care guide. Although the existing partograph has not reached its full potential, midwives showed a reluctance to change it for something new. Feedback from participants has been fed into the development phase of the guide, informing its presentation, contents and field testing.
A reliability test system for educational purposes-basic distribution system data and results

A description is presented of an electrical distribution system for use in teaching power system reliability evaluation. It includes all the main elements found in practical systems. However, it is sufficiently small that students can analyze it using hand calculations and hence fully understand reliability models and evaluations techniques. All the data needed to perform basic reliability analyses are included in this work. It also contains the basic results for a range of case studies and alternative design/operating configurations. >
Host traits and environment interact to determine persistence of bat populations impacted by white‐nose syndrome

Abstract Emerging infectious diseases have resulted in severe population declines across diverse taxa. In some instances, despite attributes associated with high extinction risk, disease emergence and host declines are followed by host stabilisation for unknown reasons. While host, pathogen, and the environment are recognised as important factors that interact to determine host–pathogen coexistence, they are often considered independently. Here, we use a translocation experiment to disentangle the role of host traits and environmental conditions in driving the persistence of remnant bat populations a decade after they declined 70–99% due to white‐nose syndrome and subsequently stabilised. While survival was significantly higher than during the initial epidemic within all sites, protection from severe disease only existed within a narrow environmental space, suggesting host traits conducive to surviving disease are highly environmentally dependent. Ultimately, population persistence following pathogen invasion is the product of host–pathogen interactions that vary across a patchwork of environments.
Optimizing maritime travel time reliability

Travel time reliability optimization problems generally cannot be formulated in direct mathematical form due to complexity of precise information. Classically, qualitative form of objective function and/or constraints does not allow the decision maker to represent it in a typical form of standard optimization model. This article attempts to resolve travel time reliability optimization problem of maritime transportation. The marine vessel’s travel time consists of seven time components. The travel time reliability is considered in a possibilistic manner, and then the reliability optimization problem with budgetary constraints and stage-time limitations is formulated. Next, algorithmic framework for solution of the possibilistic programming has been proposed, followed by a suitable illustration. Finally, this article investigates the parameter sensitivity that has consequences in the marine vessel’s transportation decision making. The proposed programming model is useful in the decision support system with regard to decision about the individual marine vessel’s stage durations and their scheduling, as well as the optimal arrival time of the vessel at the destination harbor.
Thinging teachers: gleaning nearness in dis/embodied eLearning through poetic inquiry

abstract This piece aims to give glimpses of how we slide and dis/connect in embodied-virtual nodes and nets during Covid-19 lock-down, where lecturers reach from the virtual to be near students whom they normally care for in a contact university. Similar to how the concept of the global South helps us to look at the world in more encompassing richness, poetic inquiry contributes to insight by exposing diversity and difference and by grounding research in body and emotion − because traditional research might miss the grains within which the stories sing. I conducted performative interviews to engage through Zoom with three women lecturers from the Durban University of Technology, where I support staff in eLearning. For close to thirty years here, I have been ever-perplexed by how we are affected and how selves morph as we criss-cross the thin membrane between corporeal and virtual. Here, encounters are often out-the-box performances that ring with grit and great heart, as networks of tech and teacher perform feats to be near their students. Bearing in mind teachers in relation to technology as things, I explore nearness philosophically − Heidegger’s (1971) preoccupation with “when the thing things”, and then, how Irigaray (1999) extends this western philosophical concept into embodied, intuitive knowing. To understand and analyse this line of argument, I wrote poems rooted in my personal, visceral-virtual, but also natural world – thus implying that the divide between us and nature is fluid too: similar to there being no “bright red line” between us and our technological tools, as Jackson (2014, p.232) says in ‘Rethinking repair’. While rightfully many current debates concentrate on Fourth Industrial Revolution technologies such as implants, these poems invite you to spot and think about more subtle, ordinary, often overlooked, “artefacts and forms of knowledge associated with women”, to quote Judy Wajcman (2009, p.144).
Sanitary selection of sour cherry cv. Marasca (Prunus cerasus cv. Marasca) in Croatian largest plantation “Vlačine”

Sour cherry cv. Marasca is considered a native Croatian variety with the best fruit quality in the Northern Dalmatia region. The current production is not sufficient to cover the demand, therefore new orchards should be established with pathogen-tested planting material. To select virus- and bacteria-free mother trees, a survey was conducted in the largest Croatian Marasca plantation "Vlačine". ELISA on 205 trees (51 elite, 103 average, 51 below average) confirmed the presence of prunus necrotic ringspot virus (PNRSV) on 101 trees (49.3%); petunia asteroid mosaic virus (PeAMV) and prune dwarf virus (PDV) on 10 trees each (4.9%); raspberry ringspot virus (RpRSV) on 7 trees (3.4%); cherry leafroll virus (CLRV), arabis mosaic virus (ArMV) and plum pox virus (PPV) on 3 trees each (1.5%); and apple mosaic virus (ApMV) on 1 tree (0.5%). For PNRSV, significant ELISA detection sensitivity was found, with twigs in dormant period as more reliable virus source compared to leaves during the growing season. In addition, six trees were positive on little cherry virus 2 (LChV-2) by RT-PCR. Along with very frequent latent infections, following symptoms were observed during pre-harvest period: yellow spots on leaves (ApMV); yellowing, stunted growth, leafless twigs with leaves only at the tip (PDV), bark splitting (PeAMV), reduced leaf size (RpRSV), chlorotic/necrotic ring spots (PNRSV), and uneven fruit ripening (LChV-2). Eleven trees were free of all viruses and bacteria defined by EPPO cherry certification scheme, including PPV. The selected virus- and bacteria-free elite trees represent a valuable genetic source for propagation and further clonal selection. uključujući i virus šarke šljive, pokazalo se 11 stabala. Izdvojena elitna stabla bez virusa i bakterija predstavljaju vrijedan genetski materijal za razmnožavanje i daljnju klonsku selekciju. Ključne riječi: ELISA, RT-PCR, symptoms, viruses, bacteria
A Parametric Study on the Baumgarte Stabilization Method for Forward Dynamics of Constrained Multibody Systems

This paper presents and discusses the results obtained from a parametric study on the Baumgarte stabilization method for forward dynamics of constrained multibody systems. The main purpose of this work is to analyze the influence of the variables that affect the violation of constraints, chiefly the values of the Baumgarte parameters, the integration method, the time step and the quality of the initial conditions for the positions. In the sequel of this process the formulation of the rigid multibody systems is reviewed. The generalized Cartesian coordinates are selected as the variables to describe the bodies’ degrees of freedom. The formulation of the equations of motion uses the Newton-Euler approach that is augmented with the constraint equations that lead to a set of differential algebraic equations. Furthermore, the main issues related to the stabilization of the violation of constraints based on the Baumgarte approach are revised. Special attention is also given to some techniques that help in the selection process of the values of the Baumgarte parameters, namely those based on the Taylor’s series and Laplace transform technique. Finally, a slider crank mechanism with eccentricity is considered as an example of application in order to illustrated how the violation of constraints can be affected by different factors such as the Baumgarte parameters, integrator, time step and initial guesses. © 2009 ASME
MSRCall: A Multi-scale Deep Neural Network to Basecall Oxford Nanopore Sequences

MinION, a third-generation sequencer from Oxford Nanopore Technologies, is a portable device that can provide long nucleotide read data in real-time. It primarily aims to deduce the makeup of nucleotide sequences from the ionic current signals generated when passing DNA/RNA fragments through nanopores charged with a voltage difference. To determine the nucleotides from the measured signals, a translation process known as basecalling is required. However, compared to NGS basecallers, the calling accuracy of MinION still needs to be improved. In this work, a simple but powerful neural network architecture called MSRCall is proposed. MSRCall comprises a multi-scale structure, recurrent layers, a fusion block, and a CTC decoder. To better identify both short-range and long-range dependencies, the recurrent layer is redesigned to capture various time-scale features with a multi-scale structure. The results show that MSRCall outperforms other basecallers in terms of both read and consensus accuracies.
Learning to see again: Perceptual learning of simulated abnormal on- off-cell population responses in sighted individuals

Many forms of artificial sight recovery, such as electronic implants and optogenetic proteins, generally cause simultaneous, rather than complementary firing of on- and off-center retinal cells. Here, using virtual patients—sighted individuals viewing distorted input—we examine whether plasticity might compensate for abnormal neuronal population responses. Five participants were dichoptically presented with a combination of original and contrast-reversed images. Each image (I) and its contrast-reverse (Iʹ) was filtered using a radial checkerboard (F) in Fourier space and its inverse (Fʹ). [I * F′] + [Iʹ * F] was presented to one eye, and [I * F] + [Iʹ * F′] was presented to the other, such that regions of the image that produced on-center responses in one eye produced off-center responses in the other eye, and vice versa. Participants continuously improved in a naturalistic object discrimination task over 20 one-hour sessions. Pre-training and post-training tests suggest that performance improvements were due to two learning processes: learning to recognize objects with reduced visual information and learning to suppress contrast-reversed image information in a non–eye-selective manner. These results suggest that, with training, it may be possible to adapt to the unnatural on- and off-cell population responses produced by electronic and optogenetic sight recovery technologies.
Infraspecific variation of some brown Parmeliae (in Poland) – a comparison of ITS rDNA and non-molecular characters

﻿Abstract Infraspecific variation of the ITS rDNA region of some brown Parmeliae occurring in Poland is studied and compared with non-molecular characters. Haplotype networks are used to illustrate the variability within the species. Both newly-produced sequences from Central Europe and from all over the world, downloaded from the GenBank, are used. The number of haplotypes found for each taxon ranged from five in Melaneliastygia to 12 in Melaneliahepatizon and Montaneliadisjuncta; however, their numbers correlate with the number of specimens tested. New haplotypes for Melaneliaagnata, M.hepatizon and Cetrariacommixta are found. Based on our 169-sample dataset, we could not infer any geographical correlation, either locally or world-wide. Many of the analysed haplotypes were widely distributed and the same haplotype was often shared between temperate and polar populations. A comparison of molecular, morphological, anatomical and chemical characters also shows no correlation.

Low noise cooled microwave amplifiers-simulation and design

The results of a study of cooled low noise field effect transistors and transistor amplifiers are presented. The investigations were made over a broad range of temperature and frequency. The temperature dependence of equivalent circuit elements in the transistor model is reported. This makes it possible to extrapolate with sufficient accuracy the S-parameters up to frequencies where direct measurements are difficult. Suspended microstrip lines have been used in the amplifier designs in order to minimize the losses and to improve the mechanical stability. The results of the theoretical studies are illustrated with a presentation of cooled amplifiers for the ranges 0.5-4 GHz, 3.7-4.1 GHz, 4.8-5.2 GHz, 19-23 GHz and 26-28 GHz, which are designed on the basis of the theoretically obtained parameters. >
Development of a switched-capacitor DC/DC boost converter with continuous input current waveform

A new switched-capacitor (SC)-based dc/dc boost converter is presented. It features good regulation capability and continuous input current, giving lower conducted electromagnetic interference with the supply network than classical SC converters. The converter is realized by using two quasi-switched-capacitor boost converter cells. The dc voltage conversion ratio is controlled by the gate-source voltage of a quasi-switch in each cell, in order to adjust the charging trajectory of the capacitors. By renouncing inductive elements, the converter can be implemented in small size, light weight, high power density, and it is possible to fabricate it in an IC form. A prototype of a 20 W, 6 V/9 V dc/dc boost converter with overall efficiency of 74% and power density of 10 W/in/sup 3/ has been built. The state-space averaging technique is applied to study the static and dynamic behaviors of the converter.
Changes in soil physical properties under the influence of haypasture-colonizing successional grasses

This study investigated the changes in soil physical properties after the abandonment of haypastures dominated by Helictotrichon pubescens and subsequent colonization by successional grasses Brachypodium pinnatum and Calamagrostis epigejos . We also investigated if there are linear relationships among the soil physical properties in the studied soils, and the results of the soil chemical property analysis were used as an aid in the interpretation of these relationships. The studied soil was calcocambisol on limestone. Soil samples were collected in disturbed and undisturbed state, and the differences among them were analysed by Mann-Whitney U test, whereas the relationships between soil properties were analysed with simple linear regression models. Soil solid particle density was higher in the B horizons of successional grasslands (median=2.61 g/cm 3 ) than in those of haypastures (median=2.54 g/cm 3 ). The A horizons of haypastures were barely 2–3 cm deep, whereas under successional grasses their depth reached as much as 25 cm. At the same soil depth (10–12 cm), the soil colonized by successional grasses had higher total porosity (median=53.3%) and lower bulk density (median=1.18 g/cm 3 ) than those of haypasture soil (medians of 45.1% and 1.41 g/cm 3 , respectively). Soil total porosity and water holding capacity were positively linearly associated (r 2 = 0.71, P<0.0001), but they were both negatively associated with bulk density (r 2 =0.98 and r 2 =0.67, respectively, P<0.0001), which was due to strong control of humus over the soil physical properties. We showed that the prevailing grassland type should not be ignored when studying physical properties of a specific soil type. sukcesijskim travnjacima produbila i do 25 cm. Iz praktične perspektive, na istoj dubini tla (10–12 cm), tla sukcesijskih travnjaka imala su veći ukupni porozitet (medijan=53,3%) od onoga u tlima livadnih pašnjaka (medijan=45.1%) te manju volumnu gustoću (medijan=1.18 g/cm 3 ) od one u tlima livadnih pašnjaka (medijan=1.41 g/cm 3 ). Ukupni porozitet i retencijski kapacitet tla za vodu pokazali su pozitivnu međusobnu linearnu povezanost (r 2 = 0.71, P<0.0001), no oba svojstva su bila negativno linearno povezana s volumnom gustoćom tla (r 2 =0.98 and r 2 =0.67, respectively, P<0.0001), što je bila posljedica jakog utjecaja humusa na fizikalna svojstva tla. Ovo istraživanje pokazalo je da prevladavajući tip travnjaka uzeti obzir kod istraživanja fizikalnih svojstava pojedinog
