The purpose of education is first and foremost. To achieve the components of learning from each other to be interrelated and integrated (systemic-organic). Learning components may include at least learners (leaner), educators, curriculum, teaching materials, source materials, media, evaluation, environmental, objectives and learning process. So that the goal is reached, all components must be organized well between each other resulting in an integrative cooperation. Therefore, teachers must not only pay attention to certain components, but have to consider those components as a whole. The learning process is an important thing to be considered by the manager of education. It is at least cover; approaches, strategies, methods, techniques, tactics, models, and designs. Design learning strategy is a necessity to achieve the learning objectives, namely to establish a framework or plan learning approach as a systematic way of communicating learning materials for learners to achieve the learning objectives. The learning objectives can be achieved effectively and efficiently relies heavily on learning strategies. In determining and developing learning strategies should at least pay attention to the learning objectives, characteristics of the field of study, circumstances and conditions of the students. With good design learning strategies  can deliver the expected achievement of learning objectives.

Features of Automatic Control of Technological Parameters of Water Level in the Drum Steam Boilers
Authors: Siddikov Isamiddin , Umurzakova Dilnoza
Published: July 2019

The three-pulse system of automatic control of the water level in the boiler drum received maximum distribution in the energy sector, as well as its modifications, which have the following disadvantages : the presence of static control errors at the end of the transition process in the development of internal disturbances and disturbances of superheated steam flow; large level deviations with sharp and significant changes in the load, which often leads to unloading or shutdown of the boiler or power unit. To eliminate these drawbacks, invariant systems for automatic regulation of the power supply of the drum boiler were previously developed. In work the system of automatic control of technological parameters of water level in a drum of steam boilers is considered. The description of control systems and a detailed description of the electrical power systems of the control system are given. Various methods of tuning the PI controller of a typical three-pulse automatic power control system are considered. The application of the method of structural-parametric optimization and the theory of invariance makes it possible by changing the structure of the system and optimizing the dynamic adjustment of the automatic power control system to significantly improve the quality of maintaining the water level in the boiler drum. Invariant automatic control systems eliminate static control errors under all influences and can significantly improve the quality of maintaining the level under variable conditions. The methods are proposed to significantly improve the quality of water level control in the boiler drum, eliminating the shortcomings of the typical automatic control system. The results of the work can be used in the design of power control systems of steam drum boilers. The results obtained can be used in the development of adaptive control systems for other thermal power facilities.
On tuning architectonics of nanoscaled assemblies of Zn-Ga-Al -based oxides obtained from layered double hydroxides precursors
Authors: Ignat Corina E , Carja Gabriela , Romila Laura E , Lutic Doina
Published: July 2019

Nanoscaled self-assemblies with engineered architectonics are important for obtaining advanced materials with specific applications in nanotechnology. We investigated here the morphology features at the nanoscale of the assemblies of the mixed oxides obtained through the thermal transformation of Zn2+Me3+ (Me=Al/Ga) layered double hydroxides (LDHs), as their “as-synthesized” form or after they were reconstructed in the aqueous solution of Ga2(SO4)3. The characteristics of ZnMe LDHs and the derived assemblies of mixed oxides were assessed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM/EDX), N2 adsorption at −196°C and thermal analyses (TG/DTG/DSC). The results revealed the formation nanoscaled assemblies of ZnO/ZnAl2O4/ZnGa2O4 and ZnO/Ga2O3/ZnGa2O4 starting from ZnMe(Me=Al/Ga) as precursors. Results point out that both the composition of the LDHs and the calcination temperatures can be used as parameters for tuning the nanomorphology features of the studied mixed oxides.
The Swift UVOT Stars Survey. III. Photometry and Color–Magnitude Diagrams of 103 Galactic Open Clusters
Authors: Siegel Michael H. , LaPorte Samuel J. , Porterfield Blair L. , Hagen Lea M. Z. , Gronwall Caryl A.
Published: July 2019

As part of the Swift/Ultraviolet-Optical Telescope Stars Survey, we present near-ultraviolet (NUV; 3000–1700 Å) point-source photometry for 103 Galactic open clusters. These data, taken over the span of the mission, provide a unique and unprecedented set of NUV point-source photometry on simple stellar populations. After applying a membership analysis fueled mostly by Gaia DR2 proper motions, we find that 49 of these 103 have clear precise color–magnitude diagrams (CMDs) amenable to investigation. We compare the CMDs to theoretical isochrones and find good agreement between the theoretical isochrones and the CMDs. The exceptions are the fainter parts of the main sequence and the red giant branch in the uvw2 − uvw1 CMDs, which is most likely due to either the difficulty of correcting for the red leak in the uvw2 filter or limitations in our understanding of UV opacities for cool stars. For the most part, our derived cluster parameters—age, distance, and reddening—agree with the consensus literature, but we find a few clusters that warrant substantial revision from literature values, notably NGC 2304, NGC 2343, NGC 2360, NGC 2396, NGC 2428, NGC 2509, NGC 2533, NGC 2571, NGC 2818, Collinder 220, and NGC 6939. A number of these are clusters in the third Galactic quadrant, where previous studies may have mistaken the disk sequence for the cluster. However, the Gaia DR2 proper motions clearly favor a different sequence. A number of clusters also show white dwarf and blue straggler sequences. We confirm the presence of extended main-sequence turnoffs in NGC 2360 and NGC 2818 and show hints of them in a number of other clusters that may warrant future spectroscopic study. Most of the clusters in the study have low extinction, and the rest are well fit by a “Milky Way–like” extinction law. However, Collinder 220 hints at a possible “LMC-like” extinction law. We finally provide a comprehensive point-source catalog to the community as a tool for future investigation.
Rates and Properties of Supernovae Strongly Gravitationally Lensed by Elliptical Galaxies in Time-domain Imaging Surveys
Authors: Goldstein Daniel A. , Nugent Peter E. , Goobar Ariel
Published: July 2019

Supernovae that are strongly gravitationally lensed (gLSNe) by elliptical galaxies are powerful probes of astrophysics and cosmology that will be discovered systematically by wide-field, high-cadence imaging surveys such as the Zwicky Transient Facility (ZTF) and the Large Synoptic Survey Telescope (LSST). Here we use pixel-level simulations that include observing strategy, target selection, supernova properties, and dust to forecast the rates and properties of gLSNe that ZTF and LSST will find. Applying the resolution-insensitive discovery strategy of Goldstein et al., we forecast that ZTF (LSST) can discover 0.02 (0.79) 91bg-like, 0.17 (5.92) 91T-like, 1.22 (47.84) Type Ia, 2.76 (88.51) Type IIP, 0.31 (12.78) Type IIL, and 0.36 (15.43) Type Ib/c gLSNe per year, with uncertainties dominated by uncertainties in the supernova rate. We also forecast that the surveys can discover at least 3.75 (209.32) Type IIn gLSNe per year, for a total of at least 8.60 (380.60) gLSNe per year under fiducial observing strategies. ZTF gLSNe have a median z

We develop a model of the supernova–host galaxy connection and find that the vast majority of gLSN host galaxies will be multiply imaged, enabling detailed constraints on lens models with sufficiently deep high-resolution imaging taken after the supernova has faded. We release the results of our simulations as catalogs at http://portal.nersc.gov/project/astro250/glsne/.
On the Properties of a Newborn Magnetar Powering the X-Ray Transient CDF-S XT2
Authors: Xiao Di , Zhang Bin-Bin , Dai Zi-Gao
Published: July 2019

Very recently Xue et al. reported an important detection of the X-ray transient, CDF-S XT2, whose light curve is analogous to X-ray plateau features of gamma-ray burst afterglows. They suggested that this transient is powered by a remnant stable magnetar from a binary neutron star merger because several pieces of evidence (host galaxy, location, and event rate) all point toward such an assumption. In this Letter, we revisit this scenario and confirm that this X-ray emission can be well explained by the internal gradual magnetic dissipation process in an ultra-relativistic wind of the newborn magnetar. We show that both the light curve and spectral evolution of CDF-S XT2 can be well fitted by such a model. Furthermore, we can probe some key properties of the central magnetar, such as its initial spin period, surface magnetic field strength, and wind saturation Lorentz factor.

Published: July 2019

BACKGROUND: Central nervous system (CNS) tuberculosis (TB) can manifest as meningitis, abscess, tuberculoma or other manifestations. CNS TB is a rare TB complication, and its diagnosis remains a challenge since it has clinical and imaging features that resemble other diseases. Antituberculosis treatment has a significant role in determining a patient’s outcome and prevent complications and mortality. CASE PRESENTATION: Here, we report a case of CNS TB manifested as tuberculoma in immunocompetent patient complicated with spinal arachnoiditis. Despite a treatment delay, the patient still showed clinical improvement after proper treatment with a combination of antituberculosis drug and corticosteroid.CONCLUSION: Central Nervous System Tuberculoma Complicated with Spinal Arachnoiditis in Immunocompetent Patient CNS tuberculoma is a rare CNS TB manifestation, and its diagnosis remain a challenge since its clinical symptoms and radiological findings could mimic other cases such as malignancy, pyogenic abscess, toxoplasmosis, sarcoidosis, or neurocysticercosis.

We describe two new insular gecko species of the genus Cnemaspis from Tarutao, Adang, and Rawi islands in Satun Province, southern Thailand. The new species are distinguished from their congeners in having a unique combination of morphological, scalation, and color pattern characters, and by genetic divergence in the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene. Cnemaspistarutaoensissp. nov. was found to be a member of the C.kumpoli group, but is distinguished from all other species in that group by having 8–9 supralabials and 8 infralabials; 4–5 pore-bearing precloacal scales, pores rounded; 17–19 paravertebral tubercles randomly arranged; 27–29 subdigital lamellae under the fourth toe; subcaudal region yellowish, with smooth scales and a single enlarged median row; black gular markings in males and females; and 17.24–22.36% uncorrected pairwise sequence divergences. Cnemaspisadangrawisp. nov. was found to be a member of the C.siamensis group, but is distinguished from all other species in that group by having 10 supralabials and 9 infralabials; 6–8 pore-bearing precloacal scales, pores rounded and arranged in a chevron shape; 23–25 randomly arranged, separated paravertebral tubercle rows; 26–28 subdigital lamellae under the fourth toe; subcaudal scales keeled, without enlarged median row; gular region, abdomen, limbs and subcaudal region yellowish in males only; gular marking absent in males and females; and 8.30–26.38 % uncorrected pairwise sequence divergences. Cnemaspistarutaoensissp. nov. occurs in karst formations on Tarutao Island, while Cnemaspisadangrawisp. nov. is found near granitic, rocky streams on Adang and Rawi islands.

Authors: Gutierrez Marwin , Soto-Fajardo Carina , Pineda Carlos , Alfaro-Rodriguez Alfonso , Terslev Lene , Bruyn George , Iagnocco Annamaria , Bertolazzi Chiara , D’Agostino Maria Antonietta , Delle Sedie Andrea
Published: July 2019

Objective.

To provide an overview of the role of lung ultrasound (LUS) in the assessment of interstitial lung disease (ILD) in systemic sclerosis (SSc) and to discuss the state of validation supporting its clinical relevance and application in daily clinical practice.

Methods.

Original articles published between January 1997 and October 2017 were included. To identify all available studies, a detailed search pertaining to the topic of review was conducted according to guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). A systematic search was performed in PubMed and EMBASE. The quality assessment of retrieved articles was performed according to the Oxford Center for Evidence-based Medicine. The methodological quality of the studies was assessed using the Cochrane Handbook for Systematic Reviews and the Quality Assessment of Diagnostic Accuracy Studies–2 tool.

Results.

From 300 papers identified, 12 were included for the analysis. LUS passed the filter of face, content validity, and feasibility. However, there is insufficient evidence to support criterion validity, reliability, and sensitivity to change.

Conclusion.

Despite a great deal of work supporting the potential role of LUS for the assessment of ILD-SSc, much remains to be done before validating its use as an outcome measure in ILD-SSc.
Altered Homeostasis of Regulatory T Lymphocytes and Differential Regulation of STAT1/STAT5 in CD4+ T Lymphocytes in Childhood-onset Systemic Lupus Erythematosus
Authors: Holcar Marija , Goropevšek Aleš , Avčin Tadej
Published: July 2019

Objective.

Childhood-onset systemic lupus erythematosus (cSLE) is usually a more severe and aggressive disease than adult-onset SLE (aSLE), but cellular and subcellular reasons for these differences are not well understood. The present study analyzed Th subsets, STAT1/STAT5 signaling response, and cytokine profiles of cSLE.

Methods.

FOXP3+ regulatory (Treg) and effector Th subsets, expression and phosphorylation of STAT1/STAT5 in Th, and cytokine profiles were measured in the peripheral blood of patients with cSLE and healthy controls (HC), using flow cytometry and immunoassay on a biochip.

Results.

Significant correlation between expression of the activation marker HLA-DR and decreased Th counts, an increase in the percentage of FOXP3+ Th, and a decrease in the activated Treg (aTreg) subset among them were found in cSLE. In contrast to our previous findings in aSLE, no significant differences in percentages and a significant decrease in the numbers of the naive-resting Treg (rTreg) subset compared to HC were found. The percentages of CD25− cells, possibly reflecting interleukin 2 depletion, were significantly increased in cSLE aTreg, but not in the rTreg subset. Consistent with the results of our previous studies in aSLE, increased expression of STAT1, along with significant correlation between decreased Th counts and their increased basal phosphorylation of STAT5, were also found in cSLE.

Conclusion.

Our results suggest that the key difference in Treg homeostasis between cSLE and aSLE is in the rTreg subset. However, perturbed aTreg homeostasis, increased levels of STAT1 protein, and homeostatic STAT5 signaling appear to be intrinsic characteristics of the disease, present in cSLE and aSLE alike.

Published: July 2019

El acero es un material metálico muy versátil y ampliamente utilizado en la vida moderna. Desafortunadamente, este material está propenso al fenómeno de la corrosión y el pasar del tiempo, puede contribuir a la falla del producto. Para lograr minimizar este proceso se utilizan diferentes tipos de recubrimientos, debido a su eficacia, economía y facilidad de aplicación. La degradación de la película aplicada sobre el acero por los agentes atmosféricos es resultado de la combinación de diversos factores ambientales, debido a las variaciones cíclicas altamente destructivas. El presente trabajo pretende determinar la existencia de diferencias estadísticas significativas en las distribuciones del espesor de recubrimiento en sistemas dúplex (Fe/Zn/Pintura), antes y después de realizado el ensayo de humedad y temperatura con condensación en atmósfera constante, a partir de diferentes pruebas realizadas en el software Statgraphics Centurion. Se demostró la influencia de las condiciones prefijadas sobre el espesor de recubrimiento antes y después de realizado el ensayo. Dichos valores se encontraron en un intervalo adecuado para garantizar la resistencia a la corrosión, no evidenciándose deterioro visible en la superficie de las probetas analizadas.
De l’école des Beaux-arts à la leçon de Louis I. Kahn : assimilations et détournements théoriques chez Bernard Huet
Authors: Pommier Juliette
Published: July 2019

La question de l’héritage théorique interroge le rapport des théoriciens à leurs sources. Dans le parcours de Bernard Huet, théoricien de l’architecture urbaine à la française, ce rapport se construit dès sa formation pour se développer tout au long de sa carrière. La question sera ainsi abordée sous l’angle de l’enseignement et de sa capacité à produire cet héritage, au travers du processus d’assimilation. L’analyse de la confrontation de Bernard Huet au système des Beaux-arts et à l’enseignement de Louis I. Kahn tentera de cerner les modalités de l’assimilation et de l’élaboration théorique ultérieure. Plusieurs facteurs déterminent cette assimilation : le contexte de réception et la trajectoire de l’architecte, mais aussi les caractères internes de ces enseignements et les modalités d’assimilation. Celles-ci correspondent à différents mécanismes psychologiques, développés dans le temps long : la sélection des connaissances, leur déplacement, leur transformation, ou encore leur condensation, lorsque plusieurs sources convergent vers une même position théorique.
Factors Nurses in the Intensive Care Unit Consider When Making Decisions About Patient Mobility
Authors: Krupp Anna E. , Ehlenbach William J. , King Barbara
Published: July 2019

Background

Early mobility interventions in the intensive care unit can improve patients’ outcomes, yet they are not routinely implemented in many intensive care units. In an effort to identify opportunities to implement and sustain evidence-based practice, prior work has demonstrated that understanding the decision-making process of health professionals is critical for identifying opportunities to improve program implementation. Nurses are often responsible for mobilizing patients, but how they overcome barriers and make decisions to mobilize patients in the intensive care unit is not understood.

Objective

To describe processes that nurses in intensive care units use to make decisions and barriers that influence their decision-making about patient mobility.

Methods

An exploratory descriptive approach using semi-structured interviews of a purposive sample of registered nurses in 2 intensive care units at 2 hospitals was used. Interviews were transcribed and analyzed by using directed content analysis to identify categories that describe nurses’ decision-making about patient mobility.

Results

Semistructured interviews were conducted with 20 nurses in a 1-on-1 setting. Four main categories that influenced nurses’ decision-making about mobility were identified in the directed content analysis: purpose of mobility, gathering information, establishing and activating the plan, and barriers to progressing the plan.

Conclusions

Deciding to mobilize patients in the intensive care unit is a multifaceted, individualized decision made by nurses, and numerous patient-, nurse-, and unit-related factors influence that decision. Future studies that target unit culture and interprofessional perspectives are needed.
A Mouse Model for the Study of SYK Function through Chemical Genetics Demonstrates SYK-Dependent Signaling through the B Cell Receptor, but Not TLR4
Authors: Wang Wen-Horng , Krisenko Mariya O , Higgins Renee L , Morman Rosemary E , Geahlen Robert L
Published: July 2019

The SYK protein-tyrosine kinase is a well-known mediator of signals elicited by the clustering of BCR complexes and other receptors that bear components that contain one or more ITAM sequences. Additional roles for the kinase in signaling through other receptor classes also have been described. To assist in the identification of SYK-regulated processes, we developed mice lacking endogenous Syk genes but containing instead genes coding for an analogue-sensitive form of SYK (SYK-AQL). SYK-AQL supports the development of B cells, and these can be activated with both anti-IgM F(ab′)2 through the BCR and LPS through TLR4. An orthogonal inhibitor that selectively targets SYK-AQL blocks the activation of B cells by anti-IgM F(ab′)2 in SYK-AQL–expressing but not wild-type cells. The SYK-AQL–specific inhibitor, however, does not block B cell activation in response to LPS in either wild-type or SYK-AQL–expressing cells. Thus, SYK is essential for coupling the BCR but not TLR4 to the activation of B cells.

Computed tomographic scan showed thickened right superior rectus muscle and tendons. Based on the clinical and neuroimaging abnormalities a diagnosis of right orbital myositic inflammation was made. Patient was given high dose oral corticosteroids and remarkable improvement in his symptoms was recorded after 6 weeks of treatment.
Cultural attitudes to the aged: An Indian perspective
Authors: Gounden P. , Puckree T.
Published: July 2019

Institutionalization of elderly Indians seems to have been increasing with the aging of the twentieth century. This paper looks at Indian thought and cultural practice with regard to the elderly in time perspective.  Historically, although the main prescription to cultural practice and respect for the elderly came from the various Indian Scriptures, this was coloured by the specific needs of each society which changed when these societies were nomadic, settled farmers or were actively engaged in war. Later other factors like industrialization resulted in a breakdown of the extended family in which the father no matter how old or productive was the authority figure who demanded respect. This trend was also seen in published literature about the attitude of other nationalities towards their elderly. Health professionals have been grappling with the role of health care workers in achieving successful patients outcomes based on attitudes towards the elderly. More work needs to be done on this subject in this country.
The status of older persons in Africa: Challenges facing physiotherapists
Authors: Amosun S. L.
Published: July 2019

In many African countries, there has been an increase in the number of older persons because of the gains in life expectancy made in the 20th century. The increase has led to concerns about how to provide necessary care for older persons as many on-going changes in the society threaten to erode the traditional support network. The paper identifies some of the many challenges facing physiotherapists in improving the status of older persons in Africa, and gives suggestions on overcoming the challenges.
