Mapping South Baltic Near-Shore Bathymetry Using Sentinel-2 Observations
Authors: Chybicki Andrzej 
Published: October 2017

Abstract
One of the most promising new applications of remote observation satellite systems (RO) is the near-shore bathymetry estimation based on spaceborn multispectral imageries. In recent years, many experiments aiming to estimate bathymetry in optically shallow water with the use of remote optical observations have been presented. In this paper, optimal models of satellite derived bathymetry (SDB) for relatively turbid waters of the South Baltic Sea were presented. The obtained results were analysed in terms of depth error estimation, spatial distribution, and overall quality. The models were calibrated based on sounding (in-situ) data obtained by a single-beam echo sounder, which was retrieved from the Maritime Office in Gdynia, Poland. The remote observations for this study were delivered by the recently deployed European Space Agency Sentinel-2 satellite observation system. A detailed analysis of the obtained results has shown that the tested methods can be successfully applied for the South Baltic region at depths of 12-18 meters. However, significant limitations were observed. The performed experiments have revealed that the error of model calibration, expressed in meters (RMSE), equals up to 10-20% of the real depth and is, generally, case dependent. To overcome this drawback, a novel indicator of determining the maximal SDB depth was proposed. What is important, the proposed SDB quality indicator is derived only on the basis of remotely registered data and therefore can be applied operationally.

Authors: Sawicki Jerzy 
Published: October 2017

Abstract
The paper considers stationary magnetohydrodynamic flow of viscous fluid in the slot between fixed curvilinear surfaces of revolution exposed to azimuthal magnetic field. To solve the problem, the equations of boundary layer in the curvilinear coordinate system. x,θ,y, were applied. The equations of the boundary layer were solved analytically with the use of the small-parameter method. The formulas determine the field of velocity and pressure.
The Influence of Diesel Oil Improvers on Indices of Atomisation and Combustion in High-Efficiency Engines

Published: October 2017

Abstract
The process of fuel combustion in a diesel engine is determined by factors existing during liquid fuel injection and atomisation. The physicochemical properties of the fuel to a large extent decide upon the quality of this phase of cylinder fuelling. So it is important to ensure appropriate properties of a fuel affecting its atomisation and, as a result, combustion. The paper deals with the topic of diesel oil improvers and the analysis of their influence on atomisation and combustion indices. In the studies base diesel oil and a diesel fuel improved by a package of additives, were used. The process of conventional and improved fuel injection was analysed by using optical examinations. The amount of released heat was evaluated during the studies carried out on combustion. Significant aspects of the applied improvers in relation to fuel injection and its combustion have been indicated.

Published: October 2017

AbstractDiabetic foot ulcers (DFUs) are a very common cause of mortality and morbidity. The distinction between infected and non-infected DFU remains a very challenging task for clinicians in everyday practice. Even when infection is documented, the spectrum of diabetic foot infection is wide, ranging from cellulitis and soft tissue infection to osteomyelitis. Procalcitonin (PCT), a well-established sepsis biomarker, has been used in the diagnosis of several infections including osteomyelitis in patients with diabetes mellitus. This review gathers and presents all the relevant data, up until now, regarding the use of PCT as an assessment tool in diabetic patients with foot infection. Current evidence suggests that PCT levels could aid clinicians in distinguishing infected from non-infected DFUs as well as in the distinction between soft tissue infection and bone involvement, but further and larger studies are warranted to confirm these findings.
Thriving and Surviving Activities of Households During the Crisis Period. Empirical Evidence from Southeastern Europe

Published: October 2017

Abstract
We use survey data from Southeastern Europe to investigate determinants which explain thriving and surviving activities of households as their response to the changes caused by the latest global economic crisis of 2007/2008. Contrary to most of the literature that investigates these types of activities as mutually exclusive, our modelling strategy identifies and then focusses on households that have used both of them in the period of crisis. Indeed, the thriving and surviving activities were often used simultaneously and they were mutually related as joint outcomes of a wider system of influences. We identify that both components of household strategies were systematically linked to the economic performance of households and to different dimensions of social capital—generalised trust and informal networking. We also find that different social capital dimensions interact and build in their influence on the success of households—i.e. more engagement in thriving and less in surviving activities.

Published: October 2017

Zusammenfassung
Die Temperatur wird als Basisgröße für Wettervorhersage
und Klimaforschung weltweit in einem Netzwerk von ca. 1000
Messstationen regelmäßig per Radiosondierung gemessen. Der
große atmosphärische Messbereich und die wechselnden
Umgebungsbedingungen während des Aufstiegs (Temperatur, Druck,
Feuchte, Ventilation, Strahlung) stellen eine große
Herausforderung an die Messtechnik dar. Es werden die wichtigsten
Effekte bei der Messung des Temperaturprofils, wie systematische
Auswirkungen auf das Temperaturprofil, beschrieben und die
Unsicherheitsbeiträge der Messergebnisse, die sich nach den
jeweiligen Korrekturen ergeben, diskutiert. Besonderes Augenmerk wird
auf den Effekt durch die direkte und diffuse solare Einstrahlung
gerichtet. Die dadurch bei Tagmessungen in den stratosphärischen
Teilen der Radiosondenprofile verursachte systematische Erwärmung
des Temperatursensors stellt dort die dominante Messabweichung
dar. Sie kann je nach verwendetem Sensor bzw. Radiosondenmodell
mehrere Kelvin betragen. Laborexperimente in einer evakuierbaren
Kammer zur Simulation des Strahlungseffektes als Grundlage zur
Erstellung einer Strahlungskorrektur ergaben maximale Werte im Bereich
von 5 K. Die mit der Korrektur des Effektes verbundenen
Unsicherheiten überschreiten derzeit noch die Anforderungen an
stratosphärischer Temperaturmessungen von < 0, 2 K wie
sie für klimatologische Untersuchungen erforderlich sind.

Abstract
Gisselman, AS, D'Amico, M, and Smoliga, JM. Optimizing intersession reliability of heart rate variability—the effects of artifact correction and breathing type. J Strength Cond Res 34(11): 3199–3207, 2020—This study aimed to comprehensively investigate the reliability of multiple heart rate variability (HRV) parameters and to explore the influence of artifact removal and breathing condition on HRV reliability. Resting HRV was collected using Polar Team2 monitors on 41 participants (age: 19.9 ± 1.2 years; 28 females and 13 males) during 2 separate days. Within each session, participants performed 10 minutes each of spontaneous and controlled breathing (randomized order). Kubios HRV analysis software was used to analyze 180-second data epochs using “low” or “strong” artifact removal. Relative reliability was assessed using intraclass correlation coefficient (ICC2,1), and absolute reliability was quantified using mean-normalized SEM%. Time-domain and nonlinear parameters produced poor to good intersession agreement (ICC = 0.34–0.68; SEM% = 11.0–39.0) with “low” artifact removal, regardless of breathing condition. Frequency-domain parameters demonstrated fair intersession agreement during controlled breathing (ICC = 0.40–0.45; SEM% = 26.0–70.0) but poor agreement during spontaneous breathing (ICC = 0.07–0.13; SEM% = 32.0–81.0). Minimal differences in ICCs were observed between “low” and “strong” artifact removal. Thus, this study provides 3 practical applications: (a) HRV monitoring is most reliable when using time-domain and nonlinear parameters, regardless of breathing or filtering condition, but no single parameter is especially reliable. The large variation and poor intersession reliability of frequency indices during spontaneous breathing are improved by controlling breathing rate; (b) “Low” artifact removal seems superior to more aggressive artifact removal; and (c) intersession differences in HRV measurements <30% may be indicative of normal daily variation rather than true physiologic changes.

Abstract
Mizuno, T. Combined effects of static stretching and electrical stimulation on joint range of motion and muscle strength. J Strength Cond Res 33(10): 2694–2703, 2019—The purpose of this study was to examine the effects of the combination of static stretching (SS) and electrical stimulation (ES) for 8 weeks on joint range of motion (ROM), muscle strength, and muscle architecture. Thirty-one subjects were divided into 3 groups: the SS combined with ES (SS + ES) group, SS group, and control group. The SS + ES group performed calf stretching simultaneously with ES to the gastrocnemius medialis, whereas the SS group performed calf stretching only. The training regimen consisted of four 30-second sets of stretching, with 30-second rest intervals, 3 days per week for 8 weeks. The control group did not perform any intervention exercise. Before and after training, measurements were taken to determine the ankle ROM, plantar flexion 1 repetition maximum strength, muscle thickness, pennation angle, and circumference of the lower leg. The results showed that 8 weeks of training led to significant improvements in the ankle ROM and muscle thickness in both the SS + ES and SS groups. There were significant increases in plantar flexion 1 repetition maximum strength and pennation angle in all 3 groups. For all parameters, there was no difference between the SS + ES and SS groups. These results clarify that 8 weeks of SS improves joint ROM and muscle thickness and shows that there is no additional benefit gained by combining ES with SS in this particular training regime.
Enhancing Spinal Plasticity Amplifies the Benefits of Rehabilitative Training and Improves Recovery from Stroke

Published: October 2017

The limited recovery that occurs following stroke happens almost entirely in the first weeks postinjury. Moreover, the efficacy of rehabilitative training is limited beyond this narrow time frame. Sprouting of spared corticospinal tract axons in the contralesional spinal cord makes a significant contribution to sensorimotor recovery, but this structural plasticity is also limited to the first few weeks after stroke. Here, we tested the hypothesis that inducing plasticity in the spinal cord during chronic stroke could improve recovery from persistent sensorimotor impairment. We potentiated spinal plasticity during chronic stroke, weeks after the initial ischemic injury, in male Sprague-Dawley rats via intraspinal injections of chondroitinase ABC. Our data show that chondroitinase injections into the contralesional gray matter of the cervical spinal cord administered 28 d after stroke induced significant sprouting of corticospinal axons originating in the peri-infarct cortex. Chondroitinase ABC injection during chronic stroke without additional training resulted in moderate improvements of sensorimotor deficits. Importantly, this therapy dramatically potentiated the efficacy of rehabilitative training delivered during chronic stroke in a skilled forelimb reaching task. These novel data suggest that spinal therapy during chronic stroke can amplify the benefits of delayed rehabilitative training with the potential to reduce permanent disability in stroke survivors.SIGNIFICANCE STATEMENTThe brain and spinal cord undergo adaptive rewiring (“plasticity”) following stroke. This plasticity allows for partial functional recovery from stroke induced sensorimotor impairments. However, the plasticity that underlies recovery occurs predominantly in the first weeks following stroke, and most stroke survivors are left with permanent disability even after rehabilitation. Using animal models, our data show that removal of plasticity-inhibiting signals in the spinal cord (via intraspinal injections of the enzyme chondroitinase ABC) augments rewiring of circuits connecting the brain to the spinal cord, even weeks after stroke. Moreover, this plasticity can be harnessed by rehabilitative training to significantly promote sensorimotor recovery. Thus, intraspinal therapy may augment rehabilitative training and improve recovery even in individuals living with chronic disability due to stroke.
SID-1 Domains Important for dsRNA Import inCaenorhabditis elegans

Published: October 2017

AbstractIn the nematode Caenorhabditis elegans, RNA interference (RNAi) triggered by double-stranded RNA (dsRNA) spreads systemically to cause gene silencing throughout the organism and its progeny. We confirm that Caenorhabditis nematode SID-1 orthologs have dsRNA transport activity and demonstrate that the SID-1 paralog CHUP-1 does not transport dsRNA. Sequence comparison of these similar proteins, in conjunction with analysis of loss-of-function missense alleles, identifies several conserved 2–7 amino acid microdomains within the extracellular domain (ECD) that are important for dsRNA transport. Among these missense alleles, we identify and characterize a sid-1 allele, qt95, which causes tissue-specific silencing defects most easily explained as a systemic RNAi export defect. However, we conclude from genetic and biochemical analyses that sid-1(qt95) disrupts only import, and speculate that the apparent export defect is caused by the cumulative effect of sequentially impaired dsRNA import steps. Thus, consistent with previous studies, we fail to detect a requirement for sid-1 in dsRNA export, but demonstrate for the first time that SID-1 functions in the intestine to support environmental RNAi (eRNAi).

A diez años de la ley 115, ¿cómo se materializó la preocupación por la "calidad"?
Authors: Bustamante Zamudio Guillermo 
Published: October 2017

La Ley general de educación se hizo en medio de la pugna entre quienes se disputan el control del campo educativo; tal vez por eso sus contradicciones internas. Y mientras unos la tomaron como una dádiva, y la defienden como realización de las aspiraciones magisteriales; el gobierno se propuso desmovilizar un gremio cualificado e ir recortando dicha ley en función de los propósitos de la nueva política social.La Ley 115 no define la calidad; la considera una intención, un afán por ajustarse a los mandatos legales y algo que se ejecutará cuando se creen ciertas instancias. La "calidad" tal vez sea el nombre de la nueva preocupación frente a la escuela, una vez el dispositivo se ha impuesto ("cobertura") hasta el punto de ser aceptado como natural. Del poder pasamos al control; se trata de una “calidad" visible a través de evaluaciones masivas, en cuya interpretación intervienen “expertos" sin formación en educación, y cuyos resultados legitiman políticas acordadas en toda América Latina con los organismos multilaterales y la banca internacional. Se nos olvidó que hace poco hacíamos investigación -no evaluaciones masivas- e indagábamos por condiciones materiales -no por "factores asociados'-. Se buscaba una compleja y heterogénea participación de los involucrados, no simplificar la educación y encontrar culpables.Pero si bien la "calidad" es el gran consenso, pues poco se discute, no se trata de un concepto universal. El sólo hecho de hablar u obrar en su nombre no hace buena una acción o una política. Recuperar el movimiento intelectual y político de los maestros, podría contribuir a frenar la política en cuestión.
La representación social de los alumnos según su pertenencia sociocultural, en los estudiantes de la carrera docente

Published: October 2017

En este artículo, producto de una investigación, se analiza la representación social del alumno en los estudiantes de licenciaturas. Un cuestionario fue aplicado a 1.072 futuros maestros para conocer su opinión sobre los objetivos de la escuela, las dificultades de logro y sus causas, según la pertenencia de los alumnos a la clase media urbana o a los grupos urbanos marginales.De la interpretación de los datos, desde la perspectiva de la discriminación educativa destacamos que: * la pertenencia sociocultural es una condición de influencia fuerte en las posibilidades de aprendizaje; * los alumnos de clase media logran con mucha más facilidad los aprendizajes sociales y/o formales que aquellos urbanos marginales,* los comportamientos deseables se identifican con pautas culturales de clase media urbana.
