Authors: Lee Brendan , Clay Adam , Sy Eric 
Published: March 2021

Abstract
Objectives
To evaluate the number of out-of-hospital cardiac arrest (OHCA) patients eligible for extracorporeal cardiopulmonary resuscitation (ECPR) in Saskatchewan and their clinical outcomes, including survival and neurological outcomes at discharge. ECPR eligibility was assessed, using clinical criteria from the University of British Columbia (UBC), University of Michigan (UM), University of California (UC) and a restrictive ECPR criteria.
Results
We performed a retrospective cohort study of 200 OHCA patients (August 1, 2017-May 31, 2019) in Regina, Saskatchewan. Sixty-one (30%) were female, the median age was 64 years (interquartile range [IQR], 52–78), the median CPR duration was 30 minutes (IQR 12–47), and 20% survived to discharge. Two (1%) patients received ECPR but did not meet any ECPR criteria. Nineteen (10%), thirty (15%), twenty-two (11%), and seven (4%) patients were ECPR-eligible, using the UBC, UM, UC, and restrictive criteria. However, none of these patients had received ECPR. Only two (11%), two (7%), two (9%), and one (14%) of these patient(s) survived to discharge, respectively. Neurological outcomes were unfavourable among all ECPR-eligible patients. Future study at our centre will be necessary on how to implement ECPR program to further improve these outcomes.

Abstract
Background
Necrotising enterocolitis (NEC) is a devastating bowel disease, primarily affecting premature infants, with a poorly understood aetiology. Prior studies have found associations in different cases with an overabundance of particular elements of the faecal microbiota (in particular Enterobacteriaceae or Clostridium perfringens), but there has been no explanation for the different results found in different cohorts. Immunological studies have indicated that stimulation of the TLR4 receptor is involved in development of NEC, with TLR4 signalling being antagonised by the activated TLR9 receptor. We speculated that differential stimulation of these two components of the signalling pathway by different microbiota might explain the dichotomous findings of microbiota-centered NEC studies. Here we used shotgun metagenomic sequencing and qPCR to characterise the faecal microbiota community of infants prior to NEC onset and in a set of matched controls. Bayesian regression was used to segregate cases from control samples using both microbial and clinical data.
Results
We found that the infants suffering from NEC fell into two groups based on their microbiota; one with low levels of CpG DNA in bacterial genomes and the other with high abundances of organisms expressing LPS. The identification of these characteristic communities was reproduced using an external metagenomic validation dataset. We suggest that these two patterns represent the stimulation of a common pathway at extremes; the LPS leading to overstimulation of TLR4, whilst low levels of CpG fail to sufficiently stimulate TLR9.
Conclusions
The identified microbial community patterns support the concept of NEC resulting from TLR-mediated pathways. Identification of these signals suggests characteristics of the gastrointestinal microbial community to be avoided to prevent NEC. Potential pre- or pro-biotic treatments may be designed to optimise TLR signalling.

Careers have different dimensions, they can be developed in an organization and in individual way. Organizations no longer have a role in creating careers, but individuals develop careers using the organization as a tool or medium. Changes in the external and internal environment in the organization are the basic conditions why individual career dares to change. The research aimed to explore senior female managers' phenomenon that left professional and managerial careers in organizations to be entrepreneurs. Structured and in-depth interviews were conducted with 25 female entrepreneurs who had left senior manager positions at the companies. Qualitative research approaches were carried out to explore what motivated female entrepreneurs to make a career transition and how the career transition process was done. Then, the Critical Incident Technique was used to analyze the data to get responses regarding female entrepreneurs' perceptions of career transitions. From the results, there are four main categories: personal, organizational life, value and integrity, and capital. Then, there are also nine subcategories: independence and individualism, strong encouragement and family support, professional and personal life balance, organizational life, values, integrity, partner ties, mentor ties, and human capital. The personal category causes more women to make a career transition, followed by capital, value and integrity, and organizational life categories.

Bidirectional DC–AC Converter-Based Communication Solution for Microgrid
Authors: Zhang Yixuan , Ni Kai , Wang Yangang , Hu Yihua 
Published: March 2021

Abstract
The communication system of a microgrid can transfer the information of electricity price, power consumption and so on between users and the control centre. This capability is of great significance to improve the efficiency and sustainability of power facilities. In this paper, a bidirectional DC–AC converter topology is proposed to achieve the composite transmission of power and signals in microgrids. Since the transmitted signals are modulated by power switches of converters and integrated into the currents, the cost of signal couplers can be saved and the circuit structure can be simplified. In order to verify the feasibility of the proposed method, a simulation model of the proposed converter is implemented in MATLAB/Simulink. With the power supply frequency of 50 Hz, when the converter operates in the inverter mode and rectifier mode, the data transmission rate can reach 120 bit/s and 48 bit/s, respectively.
Sensorless Induction Motor Drive Based on Model Reference Adaptive System Scheme Utilising a Fictitious Resistance

Published: March 2021

Abstract
This article presents a new development of an indirect stator flux-oriented controller for sensorless speed induction motor drive utilising instantaneous and steady-state values, respectively, of a fictitious resistance symbolised as R_f. The dimension of the fictitious quantity, in this context, is the ohm, which is the difference between the stator d- and q-axis fictitious resistances. However, from the measurement of the stator voltage and currents of the machine, two independent resistance estimators are built. Therefore, the first is considered as a reference model of the induction machine (IM), and the second is considered as an adjustable model. Subsequently, the error between the states of the two models is used to drive a suitable adaptation mechanism that generates the estimation of the speed, for the adjustable model. Furthermore, the structure of the proposed estimator is free from stator resistance and eliminates the requirement of any flux computation. All the detailed simulation study is carried out in MATLAB/Simulink to validate the proposed method and to highlight the robustness and the stability of the proposed model reference adaptive system estimator.

Die verbesserten Douglasienherkünfte in Frankreich
Le douglas est planté sur 415 000 ha en France. Du fait de sa croissance rapide, sa plasticité et la qualité de son bois, le douglas occupe une place croissante dans les reboisements. Chaque année, les 700 kg de semences nécessaires pour produire les plants destinés aux reboisements sont récoltés dans huit vergers à graines. Les performances et la plasticité de ces huit variétés sont évaluées dans une large gamme de milieux en vue de fournir aux reboiseurs des conseils d’utilisation pour le court terme et des perspectives à plus long terme face au réchauffement climatique. Des mesures recueillies sur 24 sites à un stade encore juvénile (5 à 8 ans) ne montrent pas de différences marquées entre variétés pour la survie. En revanche, elles mettent en évidence des différences d’environ trois semaines entre la date de débourrement des plants du verger le plus précoce et celle du plus tardif. Sur l’ensemble des sites, hormis un verger composé de clones californiens, la supériorité de croissance en hauteur des variétés par rapport à celle d’un peuplement de l’aire naturelle utilisé comme témoin varie entre 7 et 16%. Par ailleurs, si la croissance en hauteur est très dépendante du site de test, les interactions entre variétés et sites restent très peu significatives. Cet article présente enfin la stratégie adoptée pour créer une nouvelle génération de vergers à graines, destinée à produire 1000 kg de semences par an, tenant compte d’une évolution possible des besoins en variétés de douglas souhaitées par la filière forêt bois française.

Über die Invasivität der Douglasie und ihre Auswirkungen auf Boden und Biodiversität
In der Diskussion urn die Aufrechterhaltung der Ökosysternleistungen von Wäldern irn Klirnawandel stehen dern Nutzen von gebietsfrernden Baurnarten ernsthafte Bedenken des Naturschutzes gegenüber. Die Frage, ob eine Baurnart invasiv ist oder nicht, bringt die beiden Positionen auf den Punkt. Der vorliegende Artikel überprüft den Invasivitätsstatus für die Gewähnliche Douglasie (Pseudotsuga menziesii [Mirb.] Franco), die als Zukunftsbaurnart gilt. Es wird dabei von der in der Schweiz gültigen Definition ausgegangen, wonach sich ausbreitende gebietsfrernde Arten invasiv sind, wenn sie die Biodiversität und Ökosysternleistungen beeinträchtigen oder Mensch und Urnwelt gefährden. Angesichts fehlender Hinweise auf eine selbstständige Ausbreitung der Baurnart kann die Douglasie in der Schweiz nicht als invasiv bezeichnet werden. Vergleichsstudien in Mitteleuropa belegen, dass der Anbau der Douglasie nicht nachteilig auf die Bodeneigenschaften wirkt. Irn Vergleich zu Reinund Mischbeständen aus Eiche, Buche und Fichte bieten jedoch Douglasienreinbestände ungünstigere Lebensräurne für Tier- und Pilzarten, was sich in geringeren Artenzahlen ausdrückt. Für Gefässpflanzen und Moose sind die Unterschiede stark von der Bestandesstruktur abhängig und daher steuerbar. Wir folgern daher, dass die Douglasie in naturnah bestockten Wäldern beigernischt werden kann, wobei rnagliche Auswirkungen auf die Biodiversität kontinuierlich beobachtet werden rnüssen.

Radiowave technology of resonant gas-sensor microwave telemetry
Authors: Kostin M. S. , Yarlykov A. D. 
Published: March 2021

The possibility of using microstrip reflector microwave resonators in solving problems of resonant gas-sensor telemetry on layered dielectric substrates with gas-sensitive sputtering was investigated. It is noted that the use of chemically active sputtering, for example, on the basis of zeolites having a high selective gas adsorbent kinetics in terms of speed, makes it possible to create radiosensor materials capable of changing the dielectric constant in the process of absorbing gases, as well as of sublimated vapors of solid and liquid phases of various compounds. As an alternative approach in the field of dosimetric gas monitoring, a modification of radiosensor applications based on microwave sensors is proposed, which allows using microwave solutions based on microstrip microwave resonators with active gas-sensitive sorption zeolite sputtering on a dielectric substrate to conduct gas analysis in real time. The radio-wave principle of the microstrip gas sensor analyzer was formulated. An electrodynamic model of a microstrip gas sensor analyzer in the Altair Feko environment was developed. An experiment was planned, and gas-sensor telemetry tests of ammonia vapors dissolved in water were carried out. It was established that the amount of sorbed water and ammonia in the zeolite unambiguously conforms both to the absolute value of the reflection coefficient at resonance and to the resonant frequency itself. Using the example of recording hydrogen nitride vapors it was shown that the reflection coefficient and frequency shift in the resonator, which depend on the concentration of the adsorbed gas, correspond to the saturation characteristics of the gas sensor and make it possible to repeatedly measure small concentrations of a gas that can be absorbed by zeolite at a temperature corresponding to the condition of rapid evaporation of controlled gas from the active dielectric layer, which guarantees desorption of the sensor. It was established that in order to increase the speed of the gas sensor response it is advisable to create a microstrip resonator for the resonance region of 8...10 GHz and to use a microstrip sensor substrate material with a high dielectric constant. This is due to the fact that the transition to the upper microwave frequencies will allow reducing the size of the topology of the microstrip resonator and reducing the effective area of the zeolite deposition, and, consequently, increasing the adsorption rate of the gas-sensitive layer of the active dielectric.
