AbstractThe 400–450-nm-thick Bi_4Ti_3O_12 thin films with various orientations of crystallites with respect to a normal to the (100)Si substrate plane have been studied. It is established that the crystallite orientation can be controlled by varying the composition of the 4-nm-thick Ba_ x Sr_1 – _ x TiO_3 sublayer. The use of Ba_0.4Sr_0.6TiO_3 as a sublayer leads to the growth of the Bi_4Ti_3O_12 film in the single-crystal state with plane (001) parallel to the substrate plane and with a monoclinic distortion of the crystal structure. The Ba_0.8Sr_0.2TiO_3 sublayer is shown to lead to the formation of four crystallite orientations: (111), (117), (100), and (110) and two groups of domains in the Bi_4Ti_3O_12 film; the first group with the polarization direction p-erpendicularly to the substrate and the second group with the polarization directed in the angular range 45.2°–57° with respect to a normal to the substrate. It is shown that, in the Bi_4Ti_3O_12 film with the Ba_0.8Sr_0.2TiO_3 sublayer, the polarization is directed to the substrate and is switched to new stable state with the polarization direction from the substrate when applying an external voltage higher than a critical one (4 V).

AbstractThe electron paramagnetic resonance spectra of impurity trivalent erbium ions in synthetic forsterite single crystals (Mg_2SiO_4) have been studied by the electron paramagnetic resonance method in the X and Q frequency bands. It is found that erbium ions predominantly substitute for magnesium ions in crystallographic position M1 that is characterized by the inversion symmetry of the crystal field. In this case, a pronounced effect of dimer self-organization of erbium ions during the crystal growth takes place; the effect is manifested in the fact that the concentration of erbium dimer associates consisting of two closely spaced ions bound by the spin– spin interaction is several orders of magnitude higher than the concentration of dimer associates that form randomly at a statistical distribution of impurity ions in the forsterite crystal lattice. The directions of the main magnetic axes and the parameters of the effective spin Hamiltonian describing the magnetic characteristics of impurity erbium centers have been determined.

AbstractThe T – P phase diagrams of the halogenomethane compounds (CCl_4 – _ n Br_ n , n = 0, 1, 2, 4) are calculated using a mean field model. By expanding the free energy in terms of the order parameters for the transitions of the liquid (L), rhombohedral (R), face-centered cubic (FCC) and monoclinic (M) phases in those compounds, the phase line equations are derived and they are fitted to the experimental data from the literature. This method of calculating the T – P phase diagram is satisfactory to explain the T – P measurements for the halogenomethane compounds and it can also be applied to two-component systems.

Abstract—Light-emitting organic field-effect transistors (LE-FETs) on the basis of composite films that consist of perovskite nanocrystals (CsPbBr_3) embedded in a matrix of conjugated polymer—polyfluorene (PFO)—have been obtained, and their electrical and optical properties have been investigated. Output and transfer current-voltage characteristics (I-Vs) of FETs based on PFO : CsPbBr_3 films (component ratio 1 : 1) have a slight hysteresis at temperatures of 100–300 K and are characteristic of hole transport. The hole mobility is ∼3.3 and ∼1.9 cm^2/(V s) at the modes of the saturation and low fields, respectively, at 250 K and reaches ∼5 cm^2/(V s) at 100 K. It has been shown that the application of pulsed voltage to LE-FETs based on PFO : CsPbBr_3 can reduce the ionic conductivity and provide electroluminescence in this structure at 300 K.

AbstractThe structural parameters ensuring high strength and low electrical resistance have been analyzed in Cu–Cr alloys exposed to severe plastic deformation (SPD) and aging. Specific resistance and strength characteristics have been modeled for a Cu–0.5 wt % Cr alloy with a nanostructure state caused by SPD. A comparison of modeling data with experimental values reveals the validity of the approach chosen for describing the above states. The formation of nanostructure states with high strength and low electrical resistance is shown to be due to simultaneous effects depending on the treatment conditions of materials.

AbstractLow-energy ( E = 30 keV) Ag^+ ions have been implanted into single-crystalline Si wafers (c-Si) with an implantation dose varying from 1.25 × 10^15 to 1.5 × 10^17 ions cm^–2 and an ion beam current density varying from 2 to 15 μA/cm^2. The surface morphology of implanted wafers has been examined using scanning electron microscopy, transmission electron microscopy, and atomic force microscopy, and their structure has been studied by means of reflection high-energy electron diffraction and elemental microanalysis. It has been shown that for minimal irradiation doses used in experiments, the surface layer of c-Si experiences amorphization. It has been found that when the implantation dose is in excess of the threshold value (~3.1 × 10^15 ions cm^–2), Ag nanoparticles uniformly distributed over the Si surface arise in the irradiated Si layer. At a dose exceeding 10^17 ions cm^–2, a porous Si structure is observed. In this case, the Ag nanoparticle size distribution becomes bimodal with coarse particles localized at the walls of Si pores.

AbstractA method for calculation of the I – V characteristic is proposed for a detector of visible and near-IR electromagnetic radiation based on artificial diamond with allowance for vertical flow of electric current. The method can be used when the free-path length of carriers in diamond is less than the scale of variations in the concentration of carriers. The method is used to determine the following detector characteristics: the dependence of current on voltage, distribution of carrier concentration, and electric potential for a particular variant of a photodetector based on polycrystalline diamond film consisting of nanosized single crystals doped with boron.

AbstractStructural and photoelectric properties of composite Ag:Si layers formed in the near-surface area of a single-crystal c-Si substrate by a high-dose implantation of Ag^+ ions with subsequent pulsed laser annealing (PLA) have been studied. It has been established that, as a result of ion implantation, a maximal concentration of Ag impurity ( N _Ag ~ 4 × 10^22 at/cm^3) is concentrated near the surface and drops to a level of ~10^19 at/cm^3 at a depth of ~60 nm. Meanwhile, Ag nanoparticles and silver oxide (Ag_2O) inclusions are contained in a formed thin layer of amorphized Si (a-Si). Melting of a near-surface area and diffusion redistribution of the implanted impurity have been achieved in conditions of PLA, which increases Ag concentration near the surface and at a depth of 60 nm. Dark current–voltage characteristics of a junction between a Ag:Si layer and a p -Si substrate showed formation of a diode structure as a result of PLA. Photoconductivity measurements on formed samples demonstrate the presence of a photoresponse (photo-EMF) in the range of wavelengths of 500–1200 nm, which intensity increased for samples that are subjected to PLA when increasing energy density in the pulse. The obtained results demonstrate the potential use of composite Ag:Si layers and the method of their formation in the technology of photodetectors.

AbstractsAmmonia molecular-beam epitaxy has been used to grow gallium nitride (GaN) transistor heterostructures on sapphire and silicon substrates. GaN transistors with a 1.2-mm periphery fabricated on substrates of both types exhibited similar high static characteristics: saturation current density above 0.75 A/mm, transconductance above 300 mS/mm, and breakdown voltage above 120 V. Measurements of the small-signal parameters showed that transistors based on silicon substrates possessed high gain in a frequency range up to 5 GHz; the specific output power at 1 GHz amounted to 5 W/mm for transistors on sapphire substrate and 2 W/mm for transistors on silicon substrate.

Background
Excess weight is a major risk factor for chronic diseases. In Australia, over 60% of adults are overweight or obese. The overconsumption of energy-dense nutrient-poor (EDNP) foods and low physical activity (PA) levels are key factors contributing to population obesity. New cost-effective approaches to improve population diet and PA behaviors are needed.

Objective
This 1-year randomized controlled trial (6-month intervention and 6-month follow-up) aims to investigate whether a tailored intervention using mobile technology can improve diet and PA behaviors leading to weight loss in adults (aged 18-65 years) who are overweight or obese and recruited through a social marketing campaign (LiveLighter).

Methods
All eligible participants will provide data on demographics and lifestyle behaviors online at baseline, 6 months, and 12 months. Using two-stage randomization, participants will be allocated into one of three conditions (n=200 per group): tailored feedback delivered via email at seven time points, informed by objective dietary (mobile food record app) and activity (wearable activity monitor) assessment; active control receiving no tailored feedback, but undergoing the same objective assessments as tailored feedback; and online control receiving no tailored feedback or objective assessments. Primary outcome measures at 6 and 12 months are changes in body mass, EDNP food and beverage consumption, and daily moderate-to-vigorous PA (measured via accelerometry). Secondary outcomes include change in fruit and vegetable consumption, daily sedentary behaviors, and cost effectiveness.

Results
Enrolment commenced in August 2017. Primary outcomes at 12 months will be available for analysis from September 2019.

Conclusions
Tailored email feedback provided to individuals may deliver a cost-effective strategy to overcome existing barriers to improving diet and PA. If found to be successful and cost effective, upscaling this intervention for inclusion in larger-scale interventions is highly feasible.

Authors: Watfern Chloe , Heck Chloe , Rule Chris , Baldwin Peter , Boydell Katherine M 
Published: January 2019

Background
Electronic mental health (e-mental health) programs for people with an intellectual disability are currently underexplored but may provide a way of mitigating some of the barriers that this population faces in accessing appropriate mental health services.

Objective
The aim of this study was to examine the feasibility and acceptability of Healthy Mind, an e-mental health program for adults with an intellectual disability developed by the Black Dog Institute, focusing on the design and implementation of the website.

Methods
A qualitative research design was used, which involved semistructured interviews and focus groups with people with an intellectual disability, support workers, and allied health professionals. People with an intellectual disability were also observed while using the website. A thematic analysis was used to interrogate the interview transcripts and observational field notes.

Results
Participants found the content of the website informative and appreciated the many ways that the website had been made accessible to users. Participants voiced some differing requirements regarding the way information should be presented and accessed on the website. Acknowledging different types of support needs was identified as an important issue for website dissemination.

Conclusions
The Healthy Mind website promises to provide an excellent tool for people with ID and their supporters. This research has pragmatic implications for the future development and implementation of the program, while contributing to knowledge in the broader fields of e-mental health and inclusive design for people with an intellectual disability.
Cambios sociales y evaluación de la educación en México. El caso de la lectura.
Authors: Nicolás Cisneros Silvia , Martínez Castro Alma Lucía , Pérez Maya Coralia 
Published: January 2019

A partir de la lectura de documentos oficiales, se reflexiona sobre los cambios que ha presentado el Estado mexicano, para asumirse actualmente como un estado evaluador; la participación de la Organización de Cooperación para el Desarrollo Económico (OCDE), en el diagnóstico sobre la educación en México, y la aplicación del Programa Internacional de Evaluación de Estudiantes (PISA), sus resultados y la respuesta que da el gobierno en la generación de estrategias para cambiar aptitudes de lectura de la población mexicana.
Se presentan resultados de una encuesta aplicada en el 2005, por la Procuraduría Federal del Consumidor (Profeco), para identificar cómo, a ocho años del diagnóstico de la OCDE (1997) Y a cinco de la aplicación del PISA (2000), con énfasis en la lectura, la población sigue presentando resultados negativos.
La propuesta es ya no esperar políticas públicas, ante esta necesidad urgente, adoptar una actitud reflexiva y responsable con nosotros mismos y la población con la que nos relacionamos, ya sea por razones laborales o familiares; con la certidumbre de que somos capaces de construir mejores mañanas.

El objeto de esta investigación es la evaluación de la calidad de la Atención de Enfermería en 5 Unidades de Medicina Familiar, según la opinión de los usuarios en la zona de Tlalnepantla de la Delegación Oriente del IMSS, en el Edo. de México. La variable medida es: Calidad de la atención de Enfermería en las dimensiones de estructura, procesos y resultados. EI tipo de investigación es diagnóstica, analítica, descriptiva, transversal y de campo. En los criterios de inclusión se toma en cuenta a usuarios de las unidades médicas familiares No. 52, 60, 62, 64 Y 79 de la Delegación Oriente del IMSS en Tlalnepantla. Las técnicas e instrumentos de investigación fueron: fichas de trabajo, observación, entrevista y cuestionarios. EI universo estuvo constituido por 5500 usuarios de la zona de Tlalnepantla, la población fue de 550 pacientes y la muestra fue de 535 usuarios. Se comprueba la hipótesis de trabajo que dice: Existe una alta calidad de la atención de Enfermería en las 5 unidades de Medicina Familiar según la opinión de 544 usuarios. La investigación se realizó en 1998, y en los resultados se pudo constatar que la calidad de la atención de Enfermería es "de buena a excelente", ubicándose esta percepción en las dimensiones de proceso y resultados.
En opinión de los usuarios, esa baja Calidad de Estructura se debe en parte, a los problemas por los que atraviesa el IMSS en ese periodo, dando como resultado que esos problemas se reflejan en el proceso de atención de Enfermería. De igual forma, las principales quejas que tienen los usuarios en las cinco entidades, se pudo conocer que estas quejas van en el sentido de la "Estructura" por la falta de dotación de medicamentos, de ropa, y de los servicios básicos que deben prestar las clínicas que ofrecen un primer nivel de atención: detecciones, orientaciones y capacitación a los pacientes. De igual forma, existen pocas quejas en relación a la cortesía y calidez del personal de Enfermería, lo que es reflejo de la falta de recursos humanos y el exceso de trabajo, entre otras cosas.

Published: January 2019

Roundabouts have faced a huge development in terms of designing and operation, the reason behind that is to get the most safe and functional design. The functionality is affected by different factors e.g. line width, diameter of the roundabout etc., when the capacity of the roundabout is fully utilized, queue length starts to form in the different approaches, which indicates of a minor or major issue that should be studied.
This paper discusses the different factors affecting the queue length of an approach on the roundabout (Al Falah roundabout), after obtaining the data, regression analysis was done to provide a model that can be used for estimating the volume capacity ratio from queue lengths or vice versa. Two other methods were used to compare the obtained model (HCM 2010 Method and Two Minute Rule Method), in addition to a field data collection of the actual timing needed to pass that queue length, which was assigned as the true value of the models and comparing depending on it.
Finally, the discussion of the term paper, will include the different concepts of advanced statistical analysis, the will (as expected) contain different types of distributions and the coloration between the keys of the roundabouts design, and will study the limitation and how it can be improved in future.

Abstract
OBJECTIVE To evaluate the effects of providing 100% O2, compared with provision of room air, in sedated spontaneously breathing inland bearded dragons (Pogona vitticeps).
ANIMALS 8 adult bearded dragons.
PROCEDURES Animals were sedated with alfaxalone (20 mg/kg, SC) and received 21% O2 (equivalent to room air) or 100% O2 via face mask (flow rate, 1 L/min) in a randomized, blinded, complete crossover study (2-week interval between treatments). Sedation variables, cardiopulmonary variables, venous blood gas values, and postsedation food intake were evaluated.
RESULTS Respiratory rate, heart rate, oxygen saturation, and sedation quality were comparable between treatments. Venous blood gas analysis revealed a higher total Pco2 and HCO3− concentration for the 21% O2 treatment. Postsedation food intake was not affected by the inspired oxygen fraction provided during sedation.
CONCLUSIONS AND CLINICAL RELEVANCE The fraction of inspired oxygen did not appear to have clinically relevant effects on physiologic variables of bearded dragons during and after sedation. Therefore, provision of 100% O2 can be considered for use in sedated bearded dragons without the risk of inducing hypoventilation. Similarly, failure to provide 100% O2 would be unlikely to result in clinically relevant consequences in healthy sedated bearded dragons.
