Modelo de propagación simplificado para LTE en la frecuencia de 2.1GHz
Authors: Vidal Beltrán Sergio , Degollado Rea Edgar Alan , López Bonilla José Luis
Published: September 2017

Para la frecuencia de 2.1 GHz, los modelos de propagación utilizados para estimar la atenuación de la señal en sistemas de comunicaciones móviles celulares LTE (Long Term Evolution), son principalmente el Modelo Xia-Bertoni y Walfisch-Bertoni [2, 3, 5, 9, 10, 15], los cuales son modelos aplicables hasta la frecuencia de 3GHz. Para estos modelos, las ecuaciones dependen de distintas variables del entorno de propagación (efecto de techos y altura de edificios, entre otros), lo cual los hace precisos, sin embargo, resultan más complejos en su cálculo [8, 13]. En este trabajo, se hace un análisis de las pérdidas de propagación por trayectoria usando el método empírico de pérdidas simplificado, el cual depende de menos variables que los modelos tradicionalmente usados, y por los datos recopilados en campo, presentan un mejor desempeño para la frecuencia de 2.130 GHz. En la parte final del trabajo se muestran las ecuaciones del modelo simplificado para dos áreas de la ciudad de México, las cuales son usadas para generalizar el modelo a otras áreas con características similares.
A comparative assessment of fuzzy logic and evidential belief function models for mapping artesian zone boundary in an arid region, Iraq
Authors: Al-Abadi Alaa M. , Al-Bhadili Suaad A. , Al-Ghanimy Maitham A.
Published: September 2017

This paper discusses and compares the potential application of the evidential belief function model and fuzzy logic inference system technique for spatial delineation of a groundwater artesian zone boundary in an arid region of central Iraq. First, a flowing well inventory of a total of 93 perennial flowing wells was constructed and randomly partitioned into two data sets: 70% (65 wells) for training and 30% (28 wells) for validation. Twelve groundwater conditioning factors were considered in the geospatial analysis depending on data availability and literature review. The random forest (RF) algorithm was first applied to investigate the most important conditioning factors in groundwater potential analysis. The most important factors with training flowing wells were used to develop predictive models. The prediction accuracy of the developed models was checked using the area under the relative operating characteristic curve. Results showed that the best model with a higher prediction accuracy of 86% was a fuzzy AND model followed by the evidential model with 84%. The main conclusion of this study is that the integrated use of the adapted models with RF offer a rapid assessment tool in groundwater exploration and can be helpful in groundwater management.

Authors: Zhou Bi-Hui , He Wei-Ping , Li Lin-Lin , Fan Li-Mei , Li Xiang-Rong , Li Jie
Published: September 2017

Aims and Objectives: When compared to five-membered N-heterocyclic carbene, recent reports
have demonstrated that ring expanded NHCs showed rather different properties such as increased basicity (nucleophilicity)
and greater steric demand. These unique features provide an opportunity to design new chiral
ligands. This study was undertaken to design and synthesize a series of novel enantiopure pyrimidone salts, the
precursors of N-heterocyclic carbenes, and their activity in asymmetric diethylzinc addition of arylaldehydes
was demonstrated as well.

Materials and Method:

Commercially available dimethylmalonic acid was treated with thionyl chloride to form
dimethylmalony dichloride, followed by subsequent reaction with different chiral primary amine produced corresponding
diamide. Next, conversion of diamide to monoamide was achieved by partial reduction with lithium
aluminum hydride. Finally, cyclization of monoamide with triethyl orthoformate in the presence of ammonium
salts provided pyrimidone salts in good yields.

Results:

Seven enantiopure pyrimidone salts, the precursors of N-heterocyclic carbenes, have been synthesized
starting from dimethylmalonic acid. Their applicability in asymmetric diethylzinc addition of arylaldehydes has
been demonstrated and the corresponding secondary alcohol was obtained with good yields and moderate
enantioselectivities.

Conclusion:

Herein we developed an efficient route to prepare a series of novel N-heterocyclic carbene precursors,
which were demonstrated as effective catalysts for asymmetric diethylzinc addition of arylaldehydes, and
the corresponding secondary alcohol was obtained with good yields and moderate enantioselectivities.

Authors: Ahmadi Latifeh , El-Kubbe Alia , Roney Sarah K.
Published: September 2017

Unripe grape juice (verjuice) may offer health benefits, including the treatment of cardiovascular disease. The presence of bioactive compounds in verjuice influences blood pressure, inflammatory markers, oxidative stress, endothelial function, fatty streak formation and glycemic level. Studies have shown that the bioactive compounds also affect serum lipid profile, raising LDL cholesterol under certain circumstances. The health-promoting effects of verjuice have been investigated through human and animal trials. This review paper provides a comprehensive summary of the literature on the pharmacological and phytochemical properties of green grape juice. Further research on this juice is needed to quantify the phytochemical composition and support the current findings. Furthermore, future studies are needed to determine the exact amount of verjuice required to exhibit the optimal health effects on humans, as this is currently unknown.

Entre os resultados, apontamos que as representações do rural brasileiro veiculadas no programa oscilam numa polaridade definida pela themata que reconhece a oposição entre um espaço de oportunidades e ambiente de privações, construídas principalmente a partir de associações atribuídas ao urbano ou a distinções operadas desde o espaço urbano.
REPRESENTAÇÕES MEDIÁTICAS DO RURAL BRASILEIRO EM UMA PERSPECTIVA PÓS-IDENTITÁRIA: o devir-rural e a experiência do Cinejordão
Authors: Yamamoto Eduardo Yuji
Published: September 2017

O texto articula fragmentos teóricos para problematizar a representação mediática do rural brasileiro. Para isso, a categoria do rural é pensada para além das formas identitárias historicamente consolidadas, mais precisamente, como zona de conflito, de evocação de vidas, comunidades, modos de existência que precede, acomete ou sucede o enunciatário, constituindo uma trama de sentido que o implica, vincula ou responsabiliza. O texto é estruturado em dois momentos: no primeiro, são apresentadas experiências comunicacionais que, de alguma maneira, tentaram organizar as populações do campo em torno de um imaginário ou ideologia; em um segundo momento, reivindica-se um princípio estético capaz de viabilizar uma implicação às obras provenientes do projeto Cinejordão (SETI/Unicentro-PR) que tem como objetivo produzir representações do rural através do cinema.

Ciência e arte operacional uma perspectiva sobre o design
Authors: Sochaczewski André Gabriel
Published: September 2017

Esse artigo apresenta a relação entre a Ciência e a Arte Operacional, que vem sendo questionada nos Estudos da Guerra por séculos. Ele examina essa relação por meio de uma metodologia que emprega uma pesquisa baseada em revisão literária, explorada com métodos mistos de investigação na busca de respostas. Assim, o artigo conclui que a Arte Operacional proporciona ao Comandante Operacional uma margem de criatividade e influência pessoal no processo de planejamento de uma Campanha ou Operação Militar. Ela permeia toda a Ciência Operacional desse planejamento, onde esta evidencia seu aspecto de racionalidade. Essa Ciência também pode se expressar no Planejamento Operacional por meio do Design Operacional, que tem nos seus conceitos o elo vital entre a Ciência e a Arte Operacional. Entretanto, o Design Operacional britânico ainda apresenta uma abrangência maior que o Desenho Operacional brasileiro, que é apenas uma representação gráfica da síntese da Linha de Ação escolhida pelo Comandante Operacional.
Pursuing national interests through international regimes the role of the unclos in shaping the arctic energy strategies of circumpolar states
Authors: Soendergaard Niels
Published: September 2017

The article analyses the role of the United Nations Convention on the Law of the Sea (UNCLOS) in shaping the energy strategies of Arctic states, and in defining the mode of their regional interactions. An institutionalist perspective is applied in order to understand the different mechanisms and incentives, which international institutions and regimes may constitute, in terms of spurring the cooperative behavior of self-interested actors. The analysis is focused upon the submissions made to the Commission on the Limits of the Continental Shelf (CLCS) by those of the circumpolar states that have ratified the UNCLOS, in order to be able to amplify their access to potential energy recourses of the Arctic subsoil. The findings indicate that this regime has constituted a significant instrument, in order to mold Arctic state´s energy strategies in line with the adherence to commonly acceptable procedures for territorial demarcation. Yet, this state of affairs relies upon the main Arctic player´s essential disposition towards avoiding conflict, and may thus ultimately depend upon antecedent variables of a broader geopolitical character.

Elsie Inglis (1864-1917) and the Scottish women’s hospitals in Serbia in the Great War. Part 2
Authors: Popovic-Filipovic Slavica
Published: September 2017

The news about the great victories of the Gallant Little Serbia in the Great War spread far and wide. Following on the appeals from the Serbian legations and the Serbian Red Cross, assistance was arriving from all over the world. First medical missions and medical and other help arrived from Russia. It was followed by the medical missions from Great Britain, France, Greece, the Netherlands, Denmark, Switzerland, America, etc. Material help and individual volunteers arrived from Poland, Canada, Australia, New Zealand, Ireland, Norway, India, Japan, Egypt, South America, and elsewhere. The true friends of Serbia formed various funds under the auspices of the Red Cross Society, and other associations. In September 1914, the Serbian Relief Fund was established in London, while in Scotland the first units of the Scottish Women?s Hospitals for Foreign Service were formed in November of the same year. The aim of this work was to keep the memory of the Scottish Women?s Hospitals in Serbia and with the Serbs in the Great War. In the history of the Serbian nation during the Great War, a special place was held by the Scottish Women?s Hospitals ? a unique humanitarian medical mission. It was the initiative of Dr. Elsie Maud Inglis (1864?1917), a physician, surgeon, promoter of equal rights for women, and with the support of the Scottish Federation of Woman?s Suffrage Societies. The Scottish Women?s Hospitals, which were completely staffed by women, by their participation in the Great War, also contributed to gender and professional equality, especially in medicine. Many of today?s achievements came about thanks to the first generations of women doctors, who fought for equality in choosing to study medicine, and working in the medical field, in time of war and peacetime.

INTELLECTUAL FREEDOM & CENSORSHIP: A TEACHING CHALLENGE
Authors: Curry Ann
Published: September 2017

The concepts of intellectual freedom and censorship are key to the practice of librarianship, and introducing students to these concepts should be an important part of any library and information science program curriculum. Teaching this topic is often problematic, however, because personal values and beliefs are involved and because many related issues continue to be unresolved not only in society but by practitioners themselves. In the experience of this teacher, a combination of readings (both current and historical), class discussions, and small group casestudyanalyses has proved to be most effective in introducing the topic since the concepts themselves are exceedingly complex and require a variety of teaching approaches.

Web Journals and Education
Authors: Monty Vivienne
Published: September 2017

The Journal is the most accepted vehicle for the dissemenation of work results and today electronic journals are very much part of that form of dissemination. Electronic Journals (E-journals) come in many forms from academic ones to zines, which are popular and irreverent for the most part. There are many e-joumals on the Internet and the Web in education. It is an ideal medium for them. In particular, e-journals in education help the cognitive learning process. The do so by complying with learning series as outlined by Piaget, Kolb, Witkins and others. Through their flexibility with hyperlinks and the varying formats they allow, e-joumals can relate to the varying leaning styles of students. Despite of all their positive aspects, there are still a number of issues of concern with this medium of publication such as copyright, stability of format, archiving, updating, indexing and the like. Nonetheless, e-journals will continue to grow and expand due to ease of access and because, in the field of education they promote an interactive learning tool.

CONDUIT FOR RESTORATION: THE PRISON LIBRARY
Authors: London D. Jarvis
Published: September 2017

At first glance, the collection of beige sandstone cottages assembled neatly in a pristine meadow seems like a unique hide-a-away college campus, or perhaps an exclusive retirement community. Every morning you can hear the sound of wild geese escaping the nearby game reserve as they soar in sorties that collidein the sky in disarray and look like tealeaves swirling against an invisible spoon.

Authors: Bucha Agostinho Inácio
Published: September 2017

A sociedade de cada país assume nos dias de hoje uma postura internacional que é efeito da abertura dos diferentes povos que incorporaram as vantagens em ter uma postura de intensificação e partilha de trocas, não só na área económica como também na social, cultural e outras. Esta nova forma de integração pressupõe que as pessoas e as organizações sejam empreendedoras, desenvolvendo a vertente exterior no sentido de criar empresas e a vertente interna no sentido de cada um aprender a ter melhor desempenho. Esta necessidade tem sido fomentada na UE que apoia o ensino do empreendedorismo desde a infância, como é o caso da Finlândia que hoje é study case de desenvolvimento. Não é objectivo deste artigo analisar as transformações económicas e outras que se têm implementado nos diferentes países desde o final do século passado, mas referir que a evolução constante e coerente é também resultado de modificação dos processos de aprendizagem em que a educação e a formação estão e estarão cada vez mais ligadas, nomeadamente na apreensão dos conhecimentos proporcionados pelo empreendedorismo.
