Theoretical and Experimental Studies of Doping Effects on Thermodynamic Properties of ( Dy , Y )-ZrO 2

Ionic oxide materials play a vital role in technical applications owing to their hightemperature capability and when used as thermal barrier coating (TBC) materials, for example, they have environmentally friendly effects such as improved fuel efficiency and reduced emissions. Doped ZrO2 based solid solution is attracting attention, whereas doping effects on thermodynamic properties are not well understood. This work reports the synthesis and characterization of doped ZrO2 with Dy 3+ and Y via a sol-gel route. The relationship between chemical composition and thermodynamic properties is investigated via experiment and molecular dynamics (MD) simulation. MD simulation has been employed to theoretically explore the crystal structure and to calculate the intrinsic thermal conductivity, which agrees well with the experiment measurement. The thermal conductivity of dense samples is lower than that of conventional 8 wt. % Y2O3 stabilized ZrO2 (equivalent to 4 mol% Y2O3 stabilized ZrO2, 4YSZ) at room temperature. The coefficient of thermal expansion is higher due to the doping Dy ion compared with that of 4YSZ. The thermochemical compatibility of Dy0.06Y0. 072Zr0.868O1. 934 with Al2O3 which is critical for the durability of the TBC system has been studied and can be maintained up to 1500°C.
Heat Drain Device for Ultrasound Imaging Probes

Ultrasound imaging probes are widely used for several types of diagnosis applications. Since the electroacoustic conversion efficiency of a probe is never 100% and in most cases the duration of clinical examination can be quite long, the surface temperature of the probe head, in contact with human body, must be kept under control. International Safety Standard EN 606012-37 [1] sets an upper limit for the surface temperature in still air of 50°C (43°C if measured when coupled thermally and acoustically with a test object having thermal and acoustical properties mimicking those of an appropriate tissue). The temperature rise is caused mainly by joule heating effect inside the active piezo-transducer and could be very important under some operating conditions (i.e. Continuous Wave Doppler (CW); Pulsed Wave (PW) Doppler; Colour Flow Mapping (CFM)). In the present work we focus our attention on a small footprint phased array probe. Temperature of the front face of the analysed probe must be reduced, because during CW and PW operating conditions it could exceed the limit imposed by International Safety Standard. We present here a detailed 3D FEM for the transducer , designed to replicate the real operation of the device and to be compared with measurement (electric and thermal) in order to optimize some key parameters of modelled materials. Then we show the way found to engage the thermal managing requirement, consisting in a very thin layer of super thermally conductive material that acts as heat drain toward a heat sink (in this paper it’s avoided to give more detail on the name and characteristics of this material for confidentiality reason). Also in this case a comparison between FEM and measurements will be presented. In particular, we will show how the transducer performance, in terms of thermal response, changes by varying the conductive layer thickness. In conclusion, a possible future work, consisting in a FEM for the transducer with an additional dissipation system based on Phase Changing Materials (PCM), will be presented. The patent of the present invention is currently under submission.
Relationship Between General and Context-Specific Attachment Orientations in a Turkish Sample

The authors explored the relationship between general and context-specific attachment orientations involving family, peer, and romantic contexts. Participants were 110 Turkish university students (50 men, 60 women). The authors used the Turkish form of K. Bartholomew and L. M. Horowitz's (1991) Relationship Questionnaire (RQ) to measure participants' general and specific attachment orientations. Using 5-point Likert-type scales, participants specified the degree to which each of the 4 descriptions of RQ (i.e., of secure, preoccupied, dismissing, and fearful orientations) represented (a) how they generally felt in close relationships; and then how they felt in their (b) family relationships, (c) romantic relationships, and (d) peer relationships. The present results indicated that participants who were generally high rather than low on a particular attachment orientation tended to be so across the 3 contexts, thereby supporting the trait-like conceptualization of attachment styles. However, the present results also supported conceptualization of attachment orientations as specific context-related tendencies because regardless of their general orientations, participants reported feeling relatively more secure in some relationships (e.g., family) than in others (e.g., romantic). The authors discussed the present results as supporting (a) the coexistence of both general and specific attachment orientations in the cognitive system and (b) the cross-cultural validity of attachment orientations.
Aerodynamic characteristics of circular cylinder and squared cylinders with and without rounded corners

Viscous flows around cylinders is a classical research topic in computational fluid dynamics (CFD) with a vast amount of practical applications in the field of aerodynamic and hydrodynamic. Many offshore applications use cylinders that range from circular cross-sections to square cylinders with rounded corners. Typical Reynolds numbers of practical applications are in the range of 10 to 10 where the so-called drag crisis occurs. Flow simulations in such conditions are extremely challenging because the flow exhibits laminar, transitional and turbulent regions. Furthermore, due to the existence of vortex shedding, the flow is not statistically steady. Although the Reynolds-Averaged Navier-Stokes (RANS) equations supplemented by eddy-viscosity models have evident shortcomings in such complex flows, there are several attempts published in the open literature to simulate this type of flows with such mathematical model. Due to the periodic nature of vortex shedding, ensemble averaging must be used for the definition of the mean flow and for the averaging of the mass and momentum balance. Therefore, the RANS equations are not statistically steady, which is usually designated by URANS. We present a study of the calculation of the flow around a square cylinder with rounded corners. We have selected the widely used shear stress transport (SST) k − ω eddy-viscosity model to solve the RANS equations with two main assumptions: two-dimensional and incompressible flow. However, before we address Validation (comparison with experimental data), we investigate the influence of the physical settings of the problem, i.e. size of the computational domain and specification of boundary conditions. Furthermore, grid and time refinement studies are performed to assess the numerical uncertainty of meaningful flow quantities for practical applications. All calculations are performed with the ReFRESCO solver.
Reflections on the 2010 AMR Decade Award: Whither the Promise? Moving Forward with Entrepreneurship As a Science of the Artificial

In this article we speak of roads taken and paths yet to be traversed. Over the past decade, entrepreneurship researchers have accumulated considerable work related to opportunities. Here we outline new possibilities opened up by that work and seek to recast entrepreneurship as a science of the artificial in three ways: understanding opportunities as made as well as found, moving beyond new combinations to transformations, and developing a new nexus around actions and interactions.
On the Interpretability of Linear Multivariate Neuroimaging Analyses : Filters , Patterns and their Relationship

Multivariate linear methods are an important tool for the analysis of neuroimaging data. However results obtained from multivariate methods are not as easy to interpret as results from mass-univariate analyses. A common misconception is that multivariate filters, that transform measured signals into neural sources of interest, can be interpreted as activation patterns, which reflect underlying neural processes. Yet filters and patterns are not the same. Here we try to create some awareness for the difference between multivariate filters and activation patterns. We show the difference in simulations and real data examples and recapitulate a simple but efficient way of transforming one into the other.
A Microbiopsy Method for Immunohistological and Morphological Analysis: A Pilot Study.

INTRODUCTION The fine aspiration microbiopsy is a relatively new biopsy technique, which allows muscle physiologists to sample skeletal muscle less invasively. However, the small sample size obtained is often deemed insufficient for certain analyses. The aim of the current study was to develop procedures for muscle fiber morphology and immunohistological analysis from a microbiopsy technique. METHODS Microbiopsies of the vastus lateralis were taken with a 14-gauge microbiopsy needle from four healthy men on two separate occasions. The tissue was oriented in a cryomold, embedded in Tissue-Tek® then frozen in liquid nitrogen cooled isopentane. The muscle sections were stained with hematoxylin and eosin, laminin, MHCI, MHCIIa, and Pax7 for fiber number, mean fiber area, muscle fiber typing, and satellite cell observation. RESULTS The mean ± SD (range) microbiopsy sample weight was 18.3 ± 2.9 mg (14-22 mg). The mean fiber number within the microbiopsy specimens was 150.4 ± 120.6 (64-366). All viable fibers were measured in each sample, and the mean fiber area was 4385.1 ± 1265.8 μm2 (977.0-10,132.93 μm2). There was no significant time difference (P = 0.69) in mean fiber area. DISCUSSION Results suggest the potential use of a "minimally invasive" muscle biopsy technique for immunohistological and morphological analysis. This could provide clinicians and investigators additional data in future research. Further investigations are needed to determine the usefulness and potential limiting factors of this technique.

This is a qualitative study conducted in order to evaluate the opinions of prospective primary school teachers about reflections of micro teaching method on music teaching skills. Study group of the research is composed of 50 prospective teachers taking music teaching course at the primary school teaching department of the Education Faculty at a university located in Mediterranean region of Turkey during spring semester of 2012-2013 academic year. Opinions of the prospective teachers have been collected by way of personal information form and an opinion form composed of seven open ended questions. According to findings derived from the study and opinions of the prospective primary school teachers, it is thought that micro teaching applications help music teaching skills of the candidate teachers develop. Under the light of study results, it is suggested that micro teaching activities be given room in the music teaching courses taken by primary school teachers during pre-service period and undergraduate education so that they can increase their experiences related to music teaching and get prepared for the profession.
Application of Bayesian Network to Total Points in NBA Games

Bettors on National Basketball Association (NBA) games commonly place wagers concerning the result of a game at time points during that game. We focus on the Totals (Over/Under) bet. Although many forecasting models have been built to predict the total number of points scored in an NBA game, they fail to provide bettors engaged in live-betting with predictions that are based on the game currently being played. We construct an Expert Bayesian Network to sequentially, as the game progresses, update the probability that the total score will exceed that set by the oddsmakers, and then use this probability to influence our wager at the end of the first, second, and third quarters. Research methods include data collection of team statistics over the last five NBA seasons, discretization of features, filter-based feature selection, and specification of the network structure using domain knowledge and statistical tests. We compare the profit of our live-betting strategy against amateur betting strategies and wagers informed by a Bayesian Network whose structure is specified using a greedy search algorithm. When applied to games played during the early 2018-2019 NBA regular season, the Expert Bayesian Network provides the only strategy that yields a profit.

A Wavelet-Based ECG Delineation with Improved P Wave Offset Detection Accuracy

In this paper, we present an improved version of ECG delineation approach based on the continuous wavelet transform and singlescale approach. The algorithm was design to detect five main ECG significant points, which are QRS onset, QRS offset, T wave offset, P wave onset and P wave offset. The introduced approach was evaluated on the standard CSE multilead database. The obtained delineation results are comparable with other methods and accomplished given database criteria. The implemented algorithm improvement significantly increases accuracy of the P wave offset detection, which was the problematic part of the previous version of this method.
THE CHARACTERIZATION OF A CORRODED EGYPTIAN BRONZE STATUE AND A STUDY OF THE DEGRADATION PHENOMENA

This paper presents the results of scientific examinations carried out on an Egyptian bronze statue discovered buried in Sais. Optical Microscopy (OM), Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS) and X-ray Diffraction (XRD) were used to understand the corrosive morphological characteristics of the patina, to investigate the corrosion products, analyze the elementary composition of the statue and to identify the corrosive factors with effects on the alteration processes. The results indicated that the statue was made of bronze alloy, with copper as the main element, besides lead and tin. Three layers of alteration products with various composition and morphology covered the substrate of the bronze alloy. XRD results indicated that the statue was subjected to many corrosive ions such as sulfur and chloride, and buried in wet soil, rich in oxygen and carbon. This study provides useful information for the restoration and protection of the statue.
Towards Sustainable Buildings in Egypt

The energy consumption in construction sector consumes a large part of the total energy produced in Egypt. The rise in energy price and its impact on the environment increase the need to study how to save the consumed energy in the construction sector. To achieve such a purpose, new building techniques are used in order to save energy in material’s manufacturing process by decreasing the weight of the construction materials and reducing energy for heating and air conditioning by using materials with high thermal insulation. Moreover, the energy can be saved through using local building materials to reduce the consumed energy of manufacturing and transporting. In this paper, the light is shed on the important types of sustainable building systems that are available recently in Egypt. In addition, it provides an evaluation of these systems in terms of their advantages and disadvantages in order to attain the suitable structural systems in Egypt. It is found that reinforced concrete system is the most suitable for buildings in cities and dense populated villages in Egypt, while load-bearing walls system is suitable for one or two stories buildings in the desert areas or low-dense villages due to decreasing the cost.

MANAGEMENT OF TYPE 2 DIABETICS BY INDIAN GUM ARABIC (Acacia nilotica) PODS POWDER

Indian Gum Arabic (Acacia nilotica) is one of the indigenous tree which has many medicinal properties. The present study was conducted to assess the effect of Indian Gum Arabic pods powder on blood glucose and lipid levels of type 2 diabetic subjects. Forty five subjects with type 2 diabetes: age 45-65 years, male or female, not on insulin therapy, not taking medicine for other health conditions and fasting blood glucose levels between (110–300 mg/dl) were divided randomly in three groups. Group I, II and III consumed 2, 3 and 4 g of pods powder daily, respectively for four weeks. The adequacy of diet, body measurements, blood glucose, lipid profile and blood pressure were measured before and after intervention. Nutritional profile of the subjects of the groups was same before and after intervention (P 0.05). The intervention did not make any significant changes on the nutritional profile of the subjects. After 28 days the pods powder reduced the fasting blood glucose (10–19%), post prandial (7-35%), triglyceride (6-18%), LDL (7–10%), total cholesterol (5-11%), VLDL (7-15%), HDL cholesterol (5-10%) and blood pressure (8-13%) of the subjects. Changes were significant in the post prandial glucose level, triglyceride and VLDL cholesterol and blood pressure levels of the third group of subjects who were taking 4 g of pods powder daily. The results of this study suggest that the inclusion of pods powder in the diet of people with type 2 diabetes will reduce risk factors associated with diabetes and cardiovascular diseases
2 Related Work 2 . 1 B-spline Surface Fitting with ‘ Ignore Areas

Reverse engineering of reliefs aims to turn an existing relief superimposed on an underlyin g surface into a geometric model which may be applied to a different base surface. Steps in thi s process include segmenting the relief from the background , and describing it as an offset height field relative to the underl ying surface. We have previously considered relief segment atio using a geometricsnake. Here, we show how to use this initial segmentation to estima te the background surface lying under the relief, which can be used (i) to refine the segmentation an d (ii) to express the relief as an offset field. Our approach fits a B-spline surface patch to the measured bac kground data surrounding the relief, while tension terms ensure this background surface smoothly continues underne ath the relief where there are no measured background data points to fit. After making an initial estimate of relief offs et height everywhere within the patch, we use a support vector machineto refine the segmentation. Tests demonstrate that this approach can accurately model t he background surface where it underlies the relief, provid ing more accurate segmentation, as well as relief height fiel d estimation. In particular, this approach provides signifi cant improvements for relief concavities with narrow mouths and can segment reliefs with small internal holes.
UWB Gain Enhancement of Horn Antennas Using Miniaturized Frequency Selective Surface

─ In this work, enhancement of the radiation performances of horn antennas are worked out within their operation bandwidth by placing the miniaturized Frequency Selective Surface (FSS)s perpendicularly into the inner part of their flares. Here each FSS consists of only a single miniaturized double-sided inverted Tshaped square unit cell designed on the low-cost FR4 with relative permittivity 4.4, loss tangent 0.0035 and thickness 1.58 mm in 3D CST environment so that it is able to focus the propagating electromagnetic waves to increase the directivity properties like a dielectric lens, while keeping the mismatching characteristics with less size and low manufacturing cost compared to its counter parts. Herein an exponentially tapered TEM horn with the operation bandwidth of 5-13 GHz is taken as an example horn antenna for measurements. From the measured results of the prototyped module, it can be observed that the proposed module keep mismatching characteristics of the horn antenna, meanwhile the gain and beam widths are enhanced to amplify the signal in the operation band without any increase in the total volume of the module or making the design bulky. Thus, it is expected that this methodology can be implemented to horn antennas effectively reducing volume and cost of communication systems. Index Terms ─ Enhancement, FSS, gain, horn antenna, TEM horn, UWB.
ACUTE MYOCARDIAL INFARCTION IN YOUNG WOMEN : A REVIEW

Acute myocardial infarction (AMI) is the leading cause of death in women worldwide. Every year, in the USA alone, more than 30,000 young women, 55 years of age are hospitalized with AMI. In recent decades, the incidence of AMI is increasing in younger women in the context of increasing metabolic syndrome, diabetes mellitus, and non-traditional risk factors such as stress, anxiety, and depression. Although women are classically considered to present with atypical chest pain, several observational data confirm that men and women experience similar rates of chest pain, with some differences in intensity, duration, radiation, and the choice of descriptors. Women also experience more number of symptoms and more prodromal symptoms compared with men. Suboptimal awareness, sociocultural and financial reasons result in pre-hospital delays in women and lower rates of access to care with resulting under treatment with guideline-directed therapies. Causes of AMI in young women include plaque-related MI, microvascular dysfunction or vasospasm, and spontaneous coronary artery dissection. Compared with men, women have greater in-hospital, early and late mortality, as a result of baseline comorbidities. Post-AMI women have lower referral to cardiac rehabilitation with more dropouts, lower levels of physical activity, and poorer improvements in health status compared with men, with higher inflammatory levels at 1-year from index presentation. Future strategies should focus on primary and secondary prevention, adherence, and post-AMI health-related quality of life. This review discusses the current evidence in the epidemiology, diagnosis, and treatment of AMI in young women.
