Authors: Wardach Marcin 
Published: January 2018

Abstract
This article contains simulation results of the Hybrid Excited Claw Pole Generator with skewed and non-skewed permanent magnets on rotor. The experimental machine has claw poles on two rotor sections, between which an excitation control coil is located. The novelty of this machine is existence of non-skewed permanent magnets on claws of one part of the rotor and skewed permanent magnets on the second one. The paper presents the construction of the machine and analysis of the influence of the PM skewing on the cogging torque and back-emf. Simulation studies enabled the determination of the cogging torque and the back-emf rms for both: the strengthening and the weakening of magnetic field. The influence of the magnets skewing on the cogging torque and the back-emf rms have also been analyzed.
Can museums and luxury brands’ perceptions be compared? How a survey and semiotics help decipher the French collective psyche, relative to cultural and commercial identities
Authors: de Kerret Gwenaelle 
Published: January 2018

AbstractMuseums and luxury brands are today getting more and more involved with each other, in their communications as in their activities. While brands are looking for a cultural recognition, museums need additional sources of funding and program events and exhibitions related to fashion creators. Obviously, luxury brands and museums share common values, as they belong to cultural identity. But to what extent can their collective psyche be compared? Are there common structures of imagery between brands and museums? These questions have been explored in research conducted in France. Combining semiotics with a quantitative method, it casts a new light on the question of social identities and their impact on the public. It reveals that brands and museums both present an embedded architecture of imagery, in which specific visual signs stand as metonymic embodiment. It also questions the notion of myth, as universal and archaic symbols appear to lay in both cultural and commercial representations.

Abstract

Objective of the article: to improve diagnosis and treatment results of patients with ischaemic and haemorrhagic strokes by means of a comprehensive in-depth review of free radical processes and the defining of patterns of their course under the conditions of stroke. During the study, the authors established the regularities for the course of free radical processes in stroke with the development of oxidative stress and the severity of peroxidelipid component, which increases in proportion to the severity of ischaemic or haemorrhagic stroke with maximum intensity in cases of adverse outcomes. Multi-stage mathematical modelling allowed for the determination of a highly effective formula for early stroke prognosis, which includes only 5 indicators used for estimation at hospitalization: consciousness level, blood glucose level, number of leukocytes in venous blood, antiperoxide activity of plasma and malondialdehyde. It was found that each of these parameters is an independent marker of hospital mortality. The consideration of all these indicators makes it possible to carry out early prognostic diagnostics with 90% probability and to timely correct treatment. We have also established digital boundaries, which are indications for the administration of energy correct therapy, the proper implementation of which has significantly improved the results of hospital treatment.
Peculiarities of hydration of Portland cement with synthetic nano-silica
Authors: Kotsay Galyna 
Published: January 2018

Abstract
Application of nano-materials in cement products significantly, improves their properties. Of course, the effectiveness of the materials depends on their quantity and the way they are introduced into the system. So far, amongst nano-materials used in construction, the most preferred was nano-silica. This research investigated the effect of synthetic precipitated nano-silica on the cement hydration as well as, on the physical and mechanical properties of pastes and mortars. Obtained results showed that admixture of nano-silica enhanced flexural and compressive strength of cement after 2 and 28 days, however, only when admixture made up 0.5% and 1.0%. On the other hand, the use of nano-silica in the amount 2% had some limitations, due to its ability to agglomerate, which resulted in deterioration of the rheological and mechanical properties.

Authors: Marushchak Uliana , Sanytsky Myroslav , Sydor Nazar 
Published: January 2018

Abstract
This paper deals with design of environmentally friendly Rapid Hardening Engineered Cementitious Composite (RHECC) nanomodified with ultrafine mineral additives, polycarboxylate ether based superplasticizer, calcium hydrosilicate nanoparticles and dispersal reinforced by fibers. The incremental coefficient of surface activity was proposed in order to estimation of ultrafine supplementary materials (fly ash, methakaolin, microsilica) efficiency. A characterization of RHECC’s compressive and flexural properties at different ages is reported in this paper. Early compressive strength of ECC is 45-50 MPa, standard strength – 84-95 MPa and parameter Rc2/Rc28 – 65–70%. The microstructure of the cement matrix and RHECC was investigated. The use of ultrafine mineral supplementary materials provides reinforcement of structure on micro- and nanoscale level (cementing matrix) due to formation of sub-microreinforcing hydrate phase as AFt- and C-S-H phases in unclinker part of cement matrix, resulting in the phenomena of “self-reinforcement” on the microstructure level. Designed RHECC may be regarded as lower brittle since the crack resistance coefficient is higher comparison to conventional fine grain concrete.

Published: January 2018

Abstract
Indoor environment has huge influence on person’s health and overall comfort. It is of great importance that we realize how essential indoor air quality is, considering we spend on average as much as 90% of our time indoors. There are many factors that affect indoor air quality: specifically, inside air temperature, relative humidity, and odors to name the most important factors. One of the key factors indicating indoor air quality is carbon dioxide (CO2) level.
The CO2 levels, measured in prefab apartment buildings, indicates substantial indoor air quality issues. Therefore, a proper education of the occupants is of utmost importance. Also, great care should be directed towards technical and technological solutions that would ensure meeting the normative indoor environment criteria, especially indoor air CO2 levels. Thanks to the implementation of new emerging autonomous technologies, such as Internet of Things (IoT), monitoring in real-time is enhanced. An area where IoT plays a major role is in the monitoring of indoor environment. IoT technology (e.g. smart meters and sensors) provide awareness of information about the quality of indoor environment. There is a huge potential for influencing behaviour of the users. Through the web application, it is possible to educate people and ensure fresh air supply.

Published: January 2018

AbstractObjectiveThis study investigated the effects of calcium on fluorosis-induced impairment in learning and memory of offspring rats.Results(1) High fluorosis significantly reduced synapse density, length of synaptic active zone, thickness of postsynaptic density, and led to abnormal changes in the structural parameter of synaptic gap width, which was significantly reduced or increased. High dietary calcium significantly reversed the abnormal changes in structural parameters, and low calcium aggravated these variations. (2) Dietary calcium resulted in nonsignificant effect on expression levels of DCX and p38.ConclusionThe results suggested that dietary calcium significantly affected hippocampal synaptic plasticity of offspring of mothers exposed to water fluorosis, but its molecular mechanism may not be related to the expression of DCX and p38 in the brain. The findings also demonstrate the important effects of maternal exposure to water fluorosis on offspring brain functions before water improvement.
Reliability and Validity of Computerized Force Platform Measures of Balance Function in Healthy Older Adults
Authors: Harro Cathy C. , Garascia Chelsea 
Published: January 2018

Background and Purpose:
Postural control declines with aging and is an independent risk factor for falls in older adults. Objective examination of balance function is warranted to direct fall prevention strategies. Force platform (FP) systems provide quantitative measures of postural control and analysis of different aspects of balance. The purpose of this study was to examine the reliability and validity of FP measures in healthy older adults.

Methods:
This study enrolled 46 healthy elderly adults, mean age 67.67 (5.1) years, who had no history of falls. They were assessed on 3 standardized tests on the NeuroCom Equitest FP system: limits of stability (LOS), motor control test (MCT), and sensory organization test (SOT). The test battery was administered twice within a 10-day period for test-retest reliability; intraclass correlation coefficients (ICCs), standard error of measurement (SEM), and minimal detectable change based on a 95% confidence interval (MDC95) were calculated. FP measures were compared with criterion clinical balance (Mini-BESTest and Functional Gait Assessment) and gait (10-m walk and 6-minute walk) measures to examine concurrent validity using Pearson correlation coefficients. Multiple linear regression analysis examined whether age and activity level were associated with FP performance. The α level was set at P < .05.

Results:
SOT composite equilibrium scores, MCT average latency, and LOS end point excursion measures all demonstrated excellent test-retest reliability (ICC = 0.90, 0.85, and 0.77, respectively), whereas moderate to good reliability was found for SOT vestibular ratio score (ICC = 0.71). There was large variability in performance in this healthy elderly cohort, resulting in relatively large MDC95 for these measures, especially for the LOS test. Fair correlations were found between LOS end point excursion and clinical balance and gait measures (r = 0.31-0.49), and between MCT average latency and gait measures only (r =−0.32). No correlations were found between SOT measures and clinical balance and gait measures. Age was only marginally significantly (P = .055) associated with LOS end point excursion but was not associated with SOT or MCT measures, and activity level was not associated with any of the FP measures.

Conclusion:
FP measures provided reliable information on balance function in healthy older adults; however, small learning effects were evident, particularly for the SOT. The SEM and MDC95 for the LOS and SOT measures were relatively large for this healthy elderly cohort. A relationship between FP measures, which assess underlying balance mechanisms, and clinical balance and gait measures was not strongly supported in this study. Further research is needed to justify the value of adding FP measures to a test battery for balance assessment in older adults without a history of falls.

Abstract
Hayes, MJ, Spits, DR, Watts, DG, and Kelly, VG. Relationship between tennis serve velocity and select performance measures. J Strength Cond Res 35(1): 190–197, 2021—The purpose of this study was to determine whether there was a relationship between tennis serve speed and isometric midthigh pull (IMTP) kinetic variables: countermovement jump (CMJ) height, shoulder internal and external rotation strength, and anthropometric measures in elite adolescent tennis players. Twenty-one elite junior tennis players from the Tennis Australia National Academy were recruited for this study (male, n = 12 and female, n = 9). Correlations between the performance variables and peak tennis serve speed were calculated using a Pearson's product-moment correlation coefficient. A significant positive correlation was found between peak serve speed and body height (r = 0.80, p < 0.01), IMTP peak force (r = 0.87, p < 0.01), CMJ height (r = 0.77, p ≤ 0.01), and impulse at 300 ms (r = 0.71, p ≤ 0.01). A significant, strong correlation was found between peak serve speed and impulse at 100 ms (r = 0.58, p ≤ 0.01), impulse at 200 ms (r = 0.64, p ≤ 0.01), internal rotation <90° (r = 0.63, p ≤ 0.01), and external rotation <90° (r = 0.63, p ≤ 0.01). Because of the significant positive correlations between IMTP variables, CMJ height and peak serve speed, strength and conditioning coaches with access to a force plate should consider using the IMTP to athletically profile athletes in regards to their strength, power, and injury risk.

Published: January 2018

Inhibitory interneurons represent 10–15% of the neurons in the somatosensory cortex, and their activity powerfully shapes sensory processing. Three major groups of GABAergic interneurons have been defined according to developmental, molecular, morphological, electrophysiological, and synaptic features. Dendritic-targeting somatostatin-expressing interneurons (SST-INs) have been shown to display diverse morphological, electrophysiological, and molecular properties and activity patternsin vivo. However, the correlation between these properties and SST-IN subtype is unclear. In this study, we aimed to correlate the morphological diversity of layer 5 (L5) SST-INs with their electrophysiological and molecular diversity in mice of either sex. Our morphological analysis demonstrated the existence of three subtypes of L5 SST-INs with distinct electrophysiological properties: T-shaped Martinotti cells innervate L1, and are low-threshold spiking; fanning-out Martinotti cells innervate L2/3 and the lower half of L1, and show adapting firing patterns; non-Martinotti cells innervate L4, and show a quasi-fast spiking firing pattern. We estimated the proportion of each subtype in L5 and found that T-shaped Martinotti, fanning-out Martinotti, and Non-Martinotti cells represent ∼10, ∼50, and ∼40% of L5 SST-INs, respectively. Last, we examined the connectivity between the three SST-IN subtypes and L5 pyramidal cells (PCs). We found that L5 T-shaped Martinotti cells inhibit the L1 apical tuft of nearby PCs; L5 fanning-out Martinotti cells also inhibit nearby PCs but they target the dendrite mainly in L2/3. On the other hand, non-Martinotti cells inhibit the dendrites of L4 neurons while avoiding L5 PCs. Our data suggest that morphologically distinct SST-INs gate different excitatory inputs in the barrel cortex.SIGNIFICANCE STATEMENTMorphologically diverse layer 5 SST-INs show different patterns of activity in behaving animals. However, little is known about the abundance and connectivity of each morphological type and the correlation between morphological subtype and spiking properties. We demonstrate a correlation between the morphological and electrophysiological diversity of layer 5 SST-INs. Based on these findings we built a classifier to infer the abundance of each morphological subtype. Last, using paired recordings combined with morphological analysis, we investigated the connectivity of each morphological subtype. Our data suggest that, by targeting different cell types and cellular compartments, morphologically diverse SST-INs might gate different excitatory inputs in the mouse barrel cortex.

Bergmann glia facilitate granule neuron migration during development and maintain the cerebellar organization and functional integrity. At present, molecular control of Bergmann glia specification from cerebellar radial glia is not fully understood. In this report, we show that ZEB2 (aka, SIP1 or ZFHX1B), a Mowat–Wilson syndrome-associated transcriptional regulator, is highly expressed in Bergmann glia, but hardly detectable in astrocytes in the cerebellum. The mice lackingZeb2in cerebellar radial glia exhibit severe deficits in Bergmann glia specification, and develop cerebellar cortical lamination dysgenesis and locomotion defects. In developingZeb2-mutant cerebella, inward migration of granule neuron progenitors is compromised, the proliferation of glial precursors is reduced, and radial glia fail to differentiate into Bergmann glia in the Purkinje cell layer. In contrast,Zeb2ablation in granule neuron precursors or oligodendrocyte progenitors does not affect Bergmann glia formation, despite myelination deficits caused byZeb2mutation in the oligodendrocyte lineage. Transcriptome profiling identified that ZEB2 regulates a set of Bergmann glia-related genes and FGF, NOTCH, and TGFβ/BMP signaling pathway components. Our data reveal that ZEB2 acts as an integral regulator of Bergmann glia formation ensuring maintenance of cerebellar integrity, suggesting that ZEB2 dysfunction in Bergmann gliogenesis might contribute to motor deficits in Mowat–Wilson syndrome.SIGNIFICANCE STATEMENTBergmann glia are essential for proper cerebellar organization and functional circuitry, however, the molecular mechanisms that control the specification of Bergmann glia remain elusive. Here, we show that transcriptional factor ZEB2 is highly expressed in mature Bergmann glia, but not in cerebellar astrocytes. The mice lackingZeb2in cerebellar radial glia, but not oligodendrocyte progenitors or granular neuron progenitors, exhibit severe defects in Bergmann glia formation. The orderly radial scaffolding formed by Bergmann glial fibers critical for cerebellar lamination was not established inZeb2mutants, displaying motor behavior deficits. This finding demonstrates a previously unrecognized critical role for ZEB2 in Bergmann glia specification, and points to an important contribution of ZEB2 dysfunction to cerebellar motor disorders in Mowat–Wilson syndrome.
Construction of Designer Selectable Marker Deletions with a CRISPR-Cas9 Toolbox in Schizosaccharomyces pombe and New Design of Common Entry Vectors
Authors: Zhao Yu , Boeke Jef D 
Published: January 2018

Abstract
Vectors encoding selectable markers have been widely used in yeast to maintain or express exogenous DNA fragments. In the fission yeast Schizosaccharomyces pombe, several engineered markers have been reported and widely used, such as ura4+ and ScLEU2 from Saccharomyces cerevisiae, which complement ura4 and leu1 mutations, respectively. These two auxotrophic markers share no homology with the S. pombe genome; however, most others can recombine with the genome due to sequence homology shared between the genomic and plasmid-borne copies of the markers. Here, we describe a CRISPR-Cas9 toolbox that can be used to quickly introduce “designer” auxotrophic marker deletions into host strains, including leu1-Δ0, his3-Δ0, and lys9-Δ0. Together with ura4-D18, this brings the total number of available designer deletion auxotrophic markers to four. The toolbox consists of a Cas9-gRNA expression vector and a donor DNA plasmid pair for each designer deletion. Using this toolbox, a set of auxotrophic S. pombe strains was constructed. Further, we reorganized essential components in the commonly used pREP series of plasmids and assembled the corresponding auxotrophic marker gene onto these plasmids. This toolbox for producing designer deletions, together with the newly developed strains and plasmids, will benefit the whole yeast community.

The purpose of this study was two-fold: examining the effect of peer coaching on EFL teachers’ professional identity and learners’ academic achievement. To this end, this very mixed-methods research was designed to see the extent to which the least investigated variable in the Iranian EFL setting. Five high school RFL teachers were triangularly coached and achievements of their classes including those of 307 EFL students were investigated. The teachers received questionnaire both before and after a 12-session coaching process while being both observed and attended a think-aloud protocol reporting. Moreover, the standardized Classroom Observation Sheet was employed whilst the coaching process. The students’ entry and exit academic behaviours in terms of achievements were measured prior to and after the treatment. Analyses of each set of data collected from each group indicated that peer coaching entailed statistically significant developments in many categories teachers’ professional identity as well as in the students’ academic achievements.Pedagogically, the findings suggest feasibility and effectiveness of conducting peer-coaching and internalizing it in our EFL educational system.
