Published: March 2017

Abstract
Commonly, relative GPS positioning technique is used in Egypt for precise positioning applications. However, the requirement of a reference station is usually problematic for some applications as it limits the operational range of the system and increases the system cost and complexity On the other hand; the single point positioning is traditionally used for low accuracy applications such as land vehicle navigation with positioning accuracy up to 10 meters in some scenarios which caused navigation problems especially in downtown areas. Recently, high positioning accuracy can be obtained through Precise Point Positioning (PPP) technique in which only once GNSS receiver is used. However, the major drawback of PPP is the long convergence time to reach to the surveying grade accuracy compared to the existing relative techniques. Moreover, the PPP accuracy is significantly degraded due to shortage in satellite availability in urban areas. To overcome these limitations, the quad constellation GNSS systems namely; GPS.GLONASS, Galileo and BeiDou can be combined to increase the satellite availability and enhance the satellite geometry which in turn reduces the convergence time. In Egypt, at the moment, the signals of both Galileo and BeiDou could be logged with limited number of satellites up to four and six satellites for both Systems respectively. In this paper, we investigated the performance of the Quad-GNSS positioning in both dual- and single-frequency ionosphere free PPP modes for both high accurate and low cost navigation application, respectively. The performance of the developed PPP models will be investigated through GNSS data sets collected at three Egyptian cities namely, Cairo, Alexandria and Aswan.

Published: March 2017

AbstractA novel two-dimensional material MXene was used to synthesize nanocomposites with linear low-density polyethylene (LLDPE). The influence of MXene on crystallization and thermal degradation kinetics of LLDPE was investigated. Non-isothermal crystallization kinetics was investigated by using differential scanning calorimetry (DSC). The experimental data was analyzed by Jeziorny theory and the Mo method. It is found that MXene acted as a nucleating agent during the non-isothermal crystallization process, and 2 wt% MXene incorporated in the nanocomposites could accelerate the crystallization rate. Findings from activation energy calculation for non-isothermal crystallization came to the same conclusion. Thermal gravity (TG) analysis of MXene/LLDPE nanocomposites was conducted at different heating rates, and the TG thermograms suggested the nanocomposites showed an improvement in thermal stability. Apparent activation energy (Ea) of thermal degradation was calculated by the Kissinger method, and Ea values of nanocomposites were higher than that of pure LLDPE. The existence of MXene seems to lead to better thermal stability in composites.

Evaluation of a Screening Program to Detect Critical Congenital Heart Defects in Newborns
Authors: Klausner Rachel , Shapiro Eugene D. , Elder Robert W. , Colson Eve , Loyal Jaspreet 
Published: March 2017

OBJECTIVES:
To report the results of and to identify problems with implementing a screening program to detect critical congenital heart defects (CCHDs) in newborns by using differential pulse oximetry (POx).

METHODS:
Charts of all live-born infants from 4 Yale–New Haven health system hospitals in Connecticut between January 1 and December 31, 2014, were reviewed.

RESULTS:
Of 10 589 newborns, 171 (1.6%) underwent an echocardiogram before screening, 10 320 (97.5%) were screened by POx, and 98 (0.9%) were not screened. Thirteen newborns (0.1%) were diagnosed with a CCHD. No infants with CCHDs were identified through POx screening (POxS) alone. Eleven (85%) were already suspected of having a CCHD lesion on the basis of prenatal ultrasound, 1 (8%) was diagnosed because of clinical concern before undergoing screening, and 1 (8%) had a false-negative screening result, but a CCHD was identified after an echocardiogram was performed because a murmur was heard. Four infants with a positive POx screen showed noncritical cardiac lesions by echocardiogram. The majority of infants were screened within the recommended 24 to 72 hours of age interval and had POx screens that were interpreted and documented correctly. Of 10 316 infants with negative POx screens, 52.1% were still in the Yale–New Haven Hospital health system at 1 year of age and no CCHD lesions were listed in their charts.

CONCLUSIONS:
Although a CCHD screening program was effectively implemented, perhaps because most children with a CCHD (85%) were detected antenatally by ultrasound, in our hospital system POxS did not lead to a substantial increase in the early identification of CCHDs.
Physicochemical characteristics of blackberry (Rubus glaucus Benth.) fruits from four production zones of Cundinamarca, Colombia
Authors: Vergara Manuel Fernando , Vargas Jessica , Acuña John Fabio 
Published: March 2017

Blackberries play an important role in human nutrition, due to the elevated content of certain bioactive compounds including ascorbate, anthocyanins, phenolic acids, carbohydrates, and proteins. Blackberry Rubus glaucus from Colombian Andes has a high demand on regional and international markets and there is much interest in its cultivation to increase the com mercial offer. In four blackberry producing municipalities of Cundinamarca province, fruits were harvested for different quality tests based on the availability of hydric resources in the zone and their influence on fruit characteristics according to the precipitation of each zone, since the crops did not have an irrigation system. The variables, such as size, fresh weight, tex ture, pH, titratable total acids (TTA), total soluble solids (TSS), and color were evaluated to compare the quality of the fruits between the municipalities, finding that fruits from Silvania had the greater size but, in turn, were the least consistent. El Colegio zone presented the sweetest fruits and together with Pasca had the highest acidity percentage. The color of Pasca and Silvania fruits was the most attractive for commercialization parameters. These parameters, even when management and agro-climatic conditions between municipalities were very similar, allows knowing the positive attributes and determine the factors that need to be improved and to project on a short-term future productions acceptable on the international market.

Purpose
This study is aimed to the investigation of the features of morphological changes in the urinary bladder of mature rats.

Results
Received results shown that the experimental group of rats that had the intake of heavy metal salts (HMS) mixture during 30 and 90 days were observed histological and immunohistochemical changes in all structures of the urinary bladder. Depending on the period of influence of heavy metal ions on the wall of the organ, the pathological changes developed in cellular layers of the wall can lead to degenerative and later to atrophic and sclerotic changes.

Conclusions
This study demonstrates that high concentrations of HMS can significantly influence the body. The histological and immunohistochemical studies showed that the influence of the HMS combination leads to deep morphological changes in all structures of the urinary bladder. These changes depend on the period of intake of HMS. Analysis of the obtained results demonstrates the dependence of expression of morphological changes in the urinary bladder on the experiment duration. The final result of these changes may lead to the disorders of bladder’s functions.

La seguridad hoy en día es un tema de gran importancia tanto en la agenda de política internacional como en la doméstica. En este sentido, la seguridad como concepto ha permeado los diferentes estamentos de la sociedad. Desde su re conceptualización, después del fin de la Guerra Fría, la seguridad como concepto ha pasado a incluir diferentes sujetos objetos de amenazas, así como una gran variedad de éstas. Las diferentes teorías de relaciones internacionales han estado presentes para explicar no sólo la dinámica propia del sistema internacional, sino que también ha fundamentado la evolución de un concepto tradicional de seguridad sustentado en el realismo político, a un nuevo concepto basado en la interdependencia compleja.
Los neoconservadores en la escena política internacional: ¿de dónde proceden?

Este artículo está parcialmente basado en la tesis doctoral El humanismo socialista de Erich Fromm. Cuius regio eius religio, defendida en 2011 en la Universidad de Extremadura por Francisco Javier Ruiz Durán. En él se muestra cómo Estados Unidos y el Reino Unido, en su esfuerzo por contener la influencia soviética sobre la Europa de la segunda postguerra mundial, terminaron creando una ideología política gracias a un gran número de intelectuales, provenientes muchos de ellos de los mismos aparatos de la Internacional Comunista, cuya ala más dura terminó conformando el movimiento neoconservador.
Classical Myths and American Abstract Expressionism: The Case of William Baziotes
Authors: Aguirre Mercedes 
Published: March 2017

Abstract Expressionism can be seen as a valid expression of the crisis of ‘Modern Man’ and, as a result, it assumed a central role in the cultural debate of its time. Within this crisis can be situated a new form of representing the ancient myths. William Baziotes, an artist who belongs to the New York School, becomes a modern ‘myth-maker’ who creates metaphors and symbols which refer to primitive cultures and primeval worlds. If a few of his paintings allude in their title to a particular Classical myth, others, without a specific title referring to a myth, have strong affinities with mythology. Classical myths seem to be entwined with the artist’s own personal myths, interpreted through his own language and his own symbols.

ABSTRACTFacing childbirth is one thing that can cause anxiety. The process of giving birth is not always only somatic, but also psychosomatic. It is because many psychological elements affect the process of giving birth. This study aimed to analyze the differences of the level anxiety in facing childbirth between primigravida and multigravida.The research was conducted with cross-sectional design using questionnaires and Hamilton Rating Scale Anxiety (HRS-A). Interviews were conducted on 43 primigravidae and multigravidae pregnant women on 3rd trimester who checkup at Puskesmas Talango Sumenep. Sample was taken by simple random sampling. Independent variables in this study were maternal characteristics, internal and external factors which cause anxiety. The dependent variable was the level of anxiety in facing labor.Testing difference in the level anxiety in the face of labor between primigravida and multigravida with Wilcoxon Mann-Whitney U test, where statistic values sig. (2-tailed) is 0,006 or p<0,05 indicating that there were differences in anxiety levels between primigravida and multigravida. The conclusions that can be drawn is that there are differences in the level of anxiety in facing childbirth between primigravida and multigravida. It is recommended for health worker to concern not only on the pregnancy but also on mother’s psychology condition. Health worker should inform husbands to accompany their wife from pregnancy to childbirth.Keyword: anxiety level, labor, primigavida, multigravid
