Avaliação do uso do rejeito gerado pelo beneficiamento da Rocha Fosfatada na Agricultura
Authors: Peixoto Claudia Marques , Henkes Jairo Afonso 
Published: July 2017

O processo de beneficiamento da rocha fosfatada para produção de ácido fosfórico por via úmida tem gerado muitos resíduos como o fosfogesso, cujas características químicas e físi-cas são semelhantes ao gesso natural (sulfato de cálcio dihidratado). O imenso volume de fosfogesso produzido anualmente pelas indústrias de produção de ácido fosfórico, vem me-recendo a atenção de órgãos de proteção radiológica e das agências de proteção ambiental do Brasil e do exterior. Trabalhos de pesquisa que visam desvendar o desenvolvimento de possíveis usos do fosfogesso, torna-se cada vez mais importante, tanto do ponto de vista econômico, como tecnológico e ambiental, uma vez que este é um resíduo abundante, de baixo custo e cujo aproveitamento evitaria o comprometimento ambiental das áreas onde este produto é armazenado. O processo mais utilizado na produção de fertilizantes fosfata-dos é aquele constituído pelo ataque da rocha fosfática com ácido sulfúrico concentrado e água. Neste caso, os principais produtos das reações químicas são o ácido fosfórico, o su-per-fosfato simples (SSP) e o super-fosfato triplo (TSP). A estocagem de grandes quantida-des de fosfogesso envolve uma série de problemas, entre os quais se destacam, a necessi-dade de dispor-se de grandes áreas para o seu armazenamento e a possibilidade, em virtu-de da sua natureza ácida, de causar impactos ao meio ambiente. Além disso, o reaprovei-tamento contribuiria para a preservação de reservas de gesso natural, garantindo assim, um dos princípios básicos do desenvolvimento sustentável, ou seja, a preservação de recursos naturais para as gerações futuras. Este trabalho pretende contribuir para o manuseio e utili-zação segura, tanto do ponto de vista agronômico como ambiental, de um dos rejeitos, no-tadamente o fosfogesso, gerado no processo de beneficiamento da rocha fosfatada, para a agricultura por meio da investigação do papel da adubação de solos na mobilidade dos ra-dionuclídeos naturais. Pretende ainda compreender os mecanismos de transferência de radionuclídeos naturais no sistema solo/planta e avaliar se o uso do fosfogesso como corre-tivo da acidez de solos contribui para um aumento significativo da concentração de radionu-clídeos nas plantas e, conseqüentemente, para um aumento da exposição dos consumido-res à radioatividade natural.

Explorando la salud, la dolencia y la enfermedad
Authors: Cuba María Sofía , Campuzano Jimmy 
Published: July 2017

La salud puede ser definida de diversas formas; una de ellas es pensarla como la suma de valores y aspiraciones de una persona y determinada por su entorno proximal y distal. El paradigma médico tradicional se enfoca en la enfermedad y no toma en cuenta la experiencia de la enfermedad en la persona, su contexto, ni busca la toma de decisiones compartidas, tampoco toma en cuenta el desarrollo de la relación médico/paciente como herramienta terapéutica. La práctica del método clínico centrado la persona y la búsqueda de evitar el daño como intervenciones innecesarias (prevención cuaternaria); pueden ser las herramientas con las cuales las y los médicos necesitan entrenarse para explorar mejor la salud, la dolencia y la enfermedad.

Authors: Somford Matthijs P. , Nieuwe Weme Rebecca A. , Sierevelt Inger , Doornberg Job N. , Niek van Dijk C. , Ring David , Eygendaal Denise ,   the Orthopaedic Eponymous Terms Study Group
Published: July 2017

Background:
There are approximately 20,000 medical eponymous terms in use today. Familiar eponymous terms serve as shorthand during communication with colleagues. This study tested the reliability of the everyday use of common orthopaedic eponymous terms.

Methods:
Using an online survey, 224 orthopaedic surgeons were quizzed on common eponymous terms. The correspondence of each eponymous term with its original description (termed appropriate use) was calculated with 95% confidence intervals. We measured the reliability of the use of eponymous terms using the kappa statistic and the proportion of agreement.

Results:
The percentage of appropriate use averaged 45% (ranging from 27% [for the Barton fracture eponymous term] to 75% [for the Sever’s disease eponymous term]), with greater misuse among European surgeons. The reliability of the use of eponymous terms was low (kappa, 0.11; proportion of agreement, 68%). The support for using eponymous terms in daily practice was significantly lower among surgeons practicing in North America (63%) than among their colleagues in Europe and South America (80%; p < 0.001). Eponymous terms were used more often than anatomical descriptions or classifications.

Conclusions:
Using eponymous terms is an inaccurate and unreliable method of communication. Descriptive terms are preferable to eponymous terms.

Synthesis of New α-Amino Phosphonates Containing 3-Amino-4(3H) Quinazolinone Moiety as Anticancer and Antimicrobial Agents: DFT, NBO, and Vibrational Studies
Authors: Awad Mohamed K. , Abdel-Aal Mahmoud F. , Atlam Faten M. , Hekal Hend A. 
Published: July 2017

Aim and Objective: Synthesis of new .-aminophosphonates containing quinazoline moiety through
Kabachnik-Fields reaction in the presence of copper triflate catalyst [32], followed by studying their antimicrobial
activities and in vitro anticancer activities against liver carcinoma cell line (HepG2) with the hope that new
anticancer agents could be developed. Also, the quantum chemical calculations are performed using density
functional theory (DFT) to study the effect of the changes of molecular and electronic structures on the biological
activity of the investigated compounds.

Materials and Method:
The structures of the synthesized compounds are confirmed by FT-IR, 1H NMR, 13C
NMR, 31P NMR and MS spectral data. The synthesized compounds show significant antimicrobial and also
remarkable cytotoxicity anticancer activities against liver carcinoma cell line (HepG2). Density functional theory
(DFT) was performed to study the effect of the molecular and electronic structure changes on the biological
activity.

Results:
It was found that the electronic structure of the substituents affects on the reaction yield. The electron
withdrawing substituent, NO2 group 3b, on the aromatic aldehydes gave a good yield more than the electron
donating substituent, OH group 3c. The electron deficient on the carbon atom of the aldehydic group may increase
the interaction of the Lewis acid (Cu(OTf)2) and the Lewis base (imine nitrogen), and accordingly, facilitate
the formation of imine easily, which is attacked by the nucleophilic phosphite species to give the α-
aminophosphonates.

Conclusion:
The newly synthesized compounds exhibit a remarkable inhibition of the growth of Grampositive,
Gram-negative bacteria and fungi at low concentrations. The cytotoxicity of the synthesized compounds
showed a significant cytotoxicity against the liver cancer cell line (HepG 2). Also, it was shown from
the quantum chemical calculations that the electron-withdrawing substituent increases the biological activity of
the α-aminophosphonates more than the electron donating group which was in a good agreement with the experimental
results. Also, a good agreement between the experimental FT-IR and the calculated one was found.
Bayesian Algorithm Based Localization of EEG Recorded Electromagnetic Brain Activity
Authors: Jatoi Munsif Ali , Kamel Nidal , Musavi Sayed Hyder Abbas , López José David 
Published: July 2017

Background:
Electrical signals are generated inside human brain due to any mental or
physical task. This causes activation of several sources inside brain which are localized using various
optimization algorithms.

Methods:
Such activity is recorded through various neuroimaging techniques like fMRI, EEG,
MEG etc. EEG signals based localization is termed as EEG source localization. The source localization
problem is defined by two complementary problems; the forward problem and the inverse
problem. The forward problem involves the modeling how the electromagnetic sources cause measurement
in sensor space, while the inverse problem refers to the estimation of the sources (causes)
from observed data (consequences). Usually, this inverse problem is ill-posed. In other words, there
are many solutions to the inverse problem that explains the same data. This ill-posed problem can
be finessed by using prior information within a Bayesian framework. This research work discusses
source reconstruction for EEG data using a Bayesian framework. In particular, MSP, LORETA and
MNE are compared.

Results:
The results are compared in terms of variational free energy approximation to model evidence
and in terms of variance accounted for in the sensor space. The results are taken for real time
EEG data and synthetically generated EEG data at an SNR level of 10dB.

Conclusion:
In brief, it was seen that MSP has the highest evidence and lowest localization error
when compared to classical models. Furthermore, the plausibility and consistency of the source reconstruction
speaks to the ability of MSP technique to localize active brain sources.

MESIN PANAS FOTO-CARNOT LUBANG HITAM NON-STASIONER
Authors: Tiandho Yuant 
Published: July 2017

Di dalam makalah ini disajikan suatu analisis teoritik dari desain mesin panas foto-Carnot dengan sumber energi berupa lubang hitam non-stasioner. Diharapkan dari kajian ini dapat diketahui potensi penggunaan lubang hitam sebagai sumber “bahan bakar” dari suatu mesin panas. Desain mesin panas berbasis lubang hitam dikembangkan karena melalui mekanika kuantum lubang hitam dapat mengemisikan partikel dan memiliki temperatur layaknya dalam proses radiasi benda hitam. Perhitungan temperatur lubang hitam non-stasioner yang meradiasikan foton dilakukan berdasarkan gambaran tunneling dengan menggunakan metode Hamilton-Jacobi. Sebagai hasilnya, lubang hitam non-stasioner memiliki temperatur yang juga bergantung terhadap laju perubahan massa. Desain mesin panas yang dikaji dalam makalah ini terdiri dari dua buah lubang hitam non-stasioner berbeda massa sehingga memiliki perbedaan tekanan radiasi yang dapat menggerakkan piston. Secara umum, efisiensi dari mesin foto-Carnot bergantung pada massa lubang hitam, laju perubahan massa, serta suatu fungsi penyeimbang dalam metrik Vaidya.Kata kunci: mesin foto-Carnot, termodinamika lubang hitam, non-stasioner. Non-Stationary Black Hole Photo-Carnot Heat Engine Abstract This paper presents a theoretical analysis of a photo-Carnot heat engine design with an energy source from a non-stationary black hole. This study may provide a clue about the potential use of black hole as a “fuel” of a heat engine. Heat engine design was developed because according to quantum mechanics a black hole may emit particles and it has temperature like in the black-body radiation. The calculation of non-stationary black hole temperature which radiate photons is based on the tunneling picture by using the Hamilton-Jacobi method. As a result, the temperature of non-stationary black hole also depends on the mass flow rate. The model of heat engine that studied in this work contains two non-stationary black holes with different masses that have different radiation pressure to move the piston. In general, the efficiency of photo-Carnot engine depend on the mass of the black hole, the mass flow rate, and the balance function in the Vaidya metric. Keywords: photo-Carnot engine, black hole thermodynamics, non-stationary.

<i>Ursamaior,</i> de Mário Cláudio: sete estrelas, um corpo cadente

Published: July 2017

<p>No ano 2000, o escritor português Mário Cláudio lança <em>Ursamaior</em>, romance que não escapa à tendência do autor de ficcionalizar dados do real. O livro, juntamente com <em>Oríon</em> (2003) e <em>Gémeos</em> (2004), compõe o que Maria Theresa Abelha Alves denomina a “Trilogia das Constelações”. O primeiro elemento desse tríptico romanesco expõe diversas formas de violência, entre as quais uma desgastante cena de estupro sofrida por Jorge, última estrela a compor a constelação de <em>Ursamaior. </em>Partiremos, portanto, dessa cena, de modo a refletir sobre o papel preponderante do lúdico sobre o corpo enlutado, aos moldes do que propõe, por exemplo, Walter Benjamin, na <em>Origem do drama barroco alemão.</em> Igualmente, procuraremos enfatizar o jogo intersemiótico que estabelece diálogo entre a literatura e outras linguagens artísticas, neste romance, notadamente, o cinema. Por fim, a escrita será entendida como forma de sutura de almas e corpos dilacerados, ou ainda como forma de reorganização do caos, destacando-se o caráter neobarroco do par luto-jogo, além da autorreflexão e da metalinguagem como estratégias textuais não raro evidenciadas pelas obras marioclaudianas.</p><p>---</p><p> </p><p><strong>DOI:</strong> <a href="http://dx.doi.org/10.22409/abriluff.2017n18a411" target="_blank">http://dx.doi.org/10.22409/abriluff.2017n18a411</a></p>
SOCIO-CULTURAL ASPECTS OF MUSEUM SERVICE
Authors: ВОРОТНИКОВА Елена , VOROTNIKOVA Elena 
Published: July 2017

The article is devoted to theoretical aspects of the museum development as a unique socio-cultural phenomenon. The author highlights the main directions and prerequisites caused the changes in the museum environment at the present stage. A museum is regarded as an important and effective public institution with purpose determined by a deep socio-cultural meaning as a symbol of culture, in which different opinions, positions and points of view coexist. Modern museum operates within the communication model revealing the multifunctional possibilities inherent in the very essence of the museum. The article considers the historical origins of the current conceptions on a museum, claimed by the Russian thinker N.F. Fedorov, as a mechanism for revitalizing social memory and the organic part of modern cultural life. The author also considers the questions of the museum community concern on the specifics of communication in the museum space, the definition of the museum sociocultural functions, the rethinking of the ways to their distinguishing, and the necessity to form such exposition "non-verbal utterances" that can be understood by visitors through "joining" to personal needs and life experience.
The article also identifies the prerequisites for the inclusion of service experts in museum activities related to the need for improving museum operating. Interprofessional interaction of museum specialists is necessary to meet public requests to the museum and to develop museum product quality – exhibition projects, adequate language texts and a variety of cultural and recreational programs considering the unique social context and cultural features of the museum audience.
