Authors: Devi Henam Sylvia , Boda Muzaffar Ahmad , Shah Mohammad Ashraf , Parveen Shazia , Wani Abdul Hamid
Published: March 2018

In this report, aqueous phase green synthesis of iron oxide nanoparticle utilizing Platanus orientalis is elucidated for the first time. The phytoconstituents of the P. orientalis leaf extract serve a dual role as reducing and capping agent during the fabrication of iron oxide nanoparticles. The role of the leaf extract in the synthesis of iron oxide has been briefly demonstrated in this work. The tailored iron oxide particles were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, infrared spectroscopy, ultraviolet-visible spectroscopy, and dynamic light scattering technique. Nonetheless, X-ray diffraction pattern reveals the mixed phase nature of the ensuing iron oxide, i.e. α-Fe2O3 and γ-Fe2O3. The spherical oxide particles have an average diameter of 38 nm as determined from transmission electron microscopy. Infrared spectroscopy results confirmed the stabilization of iron oxide nanoparticles by the phytochemicals present in the leaf extract. Iron oxide nanoparticles show significant antifungal activity against Aspergillus niger and Mucor piriformis, employed as model fungi, but found to be more active toward M. piriformis.
Formation Mechanism of Voids around Hard Inclusion during Hot Rolling Processes
Authors: Cheng Rong , Zhang Jiongming , Wang Bo
Published: March 2018

To investigate the mechanism by which voids form around hard inclusions, the deformations of a plastic slab with hard and soft inclusions that form inside it during the hot rolling process have been simulated with a finite element method. By comparing plastic strain distributions, the relative displacements of contact surfaces, and the deformations between hard and soft inclusions have preceded analysis of the formation mechanism of these voids. The variations of strain measurements between the matrix and hard inclusions cause relative displacement of their contact surfaces. Therefore, voids occur at the front and rear of the hard inclusions. Trials on the slab deformations using a titanium ball instead of the soft inclusion inside the slab during the hot rolling process are conducted. The simulated shapes of the soft inclusions with different reductions mostly agree with the experimental results.
Sasanian Amulet Practices and their Survival in Islamic Iran and Beyond
Authors: Kiyanrad Sarah
Published: March 2018

As an element of material culture and popular belief, amulets reflect the religious and cultural identity of their producers and/or wearers. However, they may also testify to centuries-old iconographical (and textual) traditions. To remain effective and to meet the prevailing religious concepts of the time, those ancient amuletic iconographies and textual elements needed to be reinterpreted. This article takes a look into continuities between Sasanian and Islamic amulet culture in Iran, focusing on the technique of binding and sealing forces referred to on many Late Antique and Islamic amulets.
Truth and Politics in Late Medieval Arabic Historiography: the Formation of Sultan Barsbāy’s State (1422‒1438) and the Narratives of the Amir Qurqumās al-Shaʿbānī (d. 1438)
Authors: Steenbergen Jo Van , Nieuwenhuyse Stijn Van
Published: March 2018

Throughout al-Ashraf Barsbāy’s reign as sultan of Mamluk Egypt and Syria (1422‒1438), one of the main performers and representatives of his expanding authority and power was the amir Qurqumās al-Shaʿbānī (d. 1438). Defeated in the power struggle that followed sultan Barsbāy’s death, Qurqumās’ career ended dramatically in his execution by order of the new sultan, al-Ẓāhir Jaqmaq (r. 1438‒1453). Whereas this amir’s rich case received substantial attention from the era’s leading Egyptian historiographers, it has so far hardly attracted any interest in modern scholarship. This article aims to remedy this, but not simply in order to pursue some detailed reconstruction of Qurqumās’ life story. It rather wishes to explore this story as a case study towards a better understanding of how extant historiographical narratives that mattered so much to Qurqumās’ contemporaries may be read in analytically more meaningful ways than traditional approaches have so far allowed for. The article therefore proposes and explores a two-tiered ‒ social and cultural ‒ method of reading contemporary historical texts as politically engaged narrative claims to historical truth. It is demonstrated how across a diverse set of narrative texts the high-profile career of the amir Qurqumās al-Shaʿbānī appears as functionally constructed around the messy relational realities of the administration of sultan Barsbāy’s justice and the performance of his warfare in Egypt, Syria, the Ḥijāz and Eastern Anatolia. It is furthermore argued that in the historiographical record of these messy realities Qurqumās’ career is made to appear through the semantics of justice and sovereignty as an agent of the legitimate and truthful political order of the formation of sultan Barsbāy’s state, but only for as long as that state existed.

Objetivo: compreender a percepção dos enfermeiros da assistência hospitalar sobre o ensino de enfermagem. Métodos: estudo qualitativo, realizado em 19 instituições hospitalares, com 56 enfermeiros. Para a coleta de dados foi utilizada a entrevista semiestruturada e, na análise, o software Atlas.ti®. Resultados: emergiram como unidades de análise: aspectos positivos e negativos do ensino de enfermagem em contexto teórico; e aspectos positivos e negativos do ensino de enfermagem em contexto prático. A percepção dos enfermeiros sobre o ensino de enfermagem está relacionada, essencialmente, à existência de processos formativos muito diversificados. Conclusão: apesar da evolução da enfermagem enquanto disciplina e profissão, os enfermeiros reconhecem que, no âmbito do ensino, muitas das fragilidades estão alicerçadas nas diferenças entre as escolas de enfermagem, sendo evidente a necessidade de maior aproximação da teoria à prática, o que implica, entre outras estratégias, o acompanhamento dos estudantes durante os estágios pelos docentes da Escola.

Authors: Endah Sukmawati Nur , Kusumaningrum Retno , Wibawa Helmie Arif
Published: March 2018

Skin detection is one of the processes to detect the presence of pornographic elements in an image. The most suitable feature for skin detection is the color feature. To be able to represent the skin color properly, it is needed to be processed in the appropriate color space. This study examines some color spaces to determine the most appropriate color space in detecting skin color. The color spaces in this case are RGB, HSV, HSL, YIQ, YUV, YCbCr, YPbPr, YDbDr, CIE XYZ, CIE L*a*b*, CIE L*u* v*, and CIE L*ch. Based on the test results using 400 image data consisting of 200 skin images and 200 non-skin images, it is obtained that the most appropriate color space to detect the color is CIE L*u*v*.
Disorders of sex development: timing of diagnosis and management in a single large tertiary center

Published: March 2018

Background

We describe the phenotypic spectrum and timing of diagnosis and management in a large series of patients with disorders of sexual development (DSD) treated in a single pediatric tertiary center.

Methods

DSD patients who had visited our tertiary center during the survey period (between 2004 and 2014) were identified based on an ICD-10 inquiry, and their phenotypic and molecular genetic findings were recorded from patient charts.

Results

Among the 550 DSD patients, 53.3% had 46,XY DSD; 37.1% had sex chromosome DSD and 9.6% had 46,XX DSD. The most common diagnoses were Turner syndrome (19.8%, diagnosed at the mean age of 4.7 ± 5.5 years), Klinefelter syndrome (14.5%, 6.8 ± 6.2 years) and bilateral cryptorchidism (23.1%). Very few patients with 46,XY DSD (7%) or 46,XX DSD (21%) had molecular genetic diagnosis. The yearly rate of DSD diagnoses remained stable over the survey period. After the release of the Nordic consensus on the management of undescended testes, the age at surgery for bilateral cryptorchidism declined significantly (P < 0.001).

Conclusions

Our results show that (i) Turner syndrome and Klinefelter syndrome, the most frequent single DSD diagnoses, are still diagnosed relatively late; (ii) a temporal shift was observed in the management of bilateral cryptorchidism, which may favorably influence patients’ adulthood semen quality and (iii) next-generation sequencing methods are not fully employed in the diagnostics of DSD patients.
Maternal inheritance of mitochondria: implications for male fertility?
Authors: Vaught R C , Dowling D K
Published: March 2018

Evolutionary theory predicts maternal inheritance of the mitochondria will lead to the accumulation of mutations in the mitochondrial DNA (mtDNA) that impair male fertility, but leave females unaffected. The hypothesis has been referred to as ‘Mother’s Curse’. There are many examples of mtDNA mutations or haplotypes, in humans and other metazoans, associated with decreases in sperm performance, but seemingly few reports of associations involving female reproductive traits; an observation that has been used to support the Mother’s Curse hypothesis. However, it is unclear whether apparent signatures of male bias in mitochondrial genetic effects on fertility reflect an underlying biological bias or a technical bias resulting from a lack of studies to have screened for female effects. Here, we conduct a systematic literature search of studies reporting mitochondrial genetic effects on fertility-related traits in gonochoristic metazoans (animals with two distinct sexes). Studies of female reproductive outcomes were sparse, reflecting a large technical sex bias across the literature. We were only able to make a valid assessment of sex specificity of mitochondrial genetic effects in 30% of cases. However, in most of these cases, the effects were male biased, including examples of male bias associated with mtDNA mutations in humans. These results are therefore consistent with the hypothesis that maternal inheritance has enriched mtDNA sequences with mutations that specifically impair male fertility. However, future research that redresses the technical imbalance in studies conducted per sex will be key to enabling researchers to fully assess the wider implications of the Mother’s Curse hypothesis to male reproductive biology.

Published: March 2018

BACKGROUND:

Food and nonalcoholic beverage companies spend millions of dollars on professional sports sponsorships, yet this form of marketing is understudied. These sponsorships are valuable marketing tools but prompt concerns when unhealthy products are associated with popular sports organizations, especially those viewed by youth.

METHODS:

This descriptive study used Nielsen audience data to select 10 sports organizations with the most 2–17 year old viewers of 2015 televised events. Sponsors of these organizations were identified and assigned to product categories. We identified advertisements promoting food and/or nonalcoholic beverage sponsorships on television, YouTube, and sports organization Web sites from 2006 to 2016, and the number of YouTube advertisement views. The nutritional quality of advertised products was assessed.

RESULTS:

Youth watched telecasts associated with these sports organizations over 412 million times. These organizations had 44 food and/or nonalcoholic beverage sponsors (18.8% of sponsors), second to automotive sponsors (n = 46). The National Football League had the most food and/or nonalcoholic beverage sponsors (n = 10), followed by the National Hockey League (n = 7) and Little League (n = 7). We identified 273 advertisements that featured food and/or nonalcoholic beverage products 328 times and product logos 83 times (some advertisements showed multiple products). Seventy-six percent (n = 132) of foods had unhealthy nutrition scores, and 52.4% (n = 111) of nonalcoholic beverages were sugar-sweetened. YouTube sponsorship advertisements totaled 195.6 million views.

CONCLUSIONS:

Sports sponsorships are commonly used to market unhealthy food and nonalcoholic beverages, exposing millions of consumers to these advertisements.
Multilayered low-strength geogrid-reinforced piled embankment
Authors: Wang Kangyu , Zhuang Yan , Liu Hanlong , Xiao Henglin
Published: March 2018

Multilayered low-stiffness geogrids have been used in constructing embankments, but without full understanding of their true behaviour – for example, the construction of apartments in Northern Ireland failed due to the excessive and continuing deformation of the load transfer platform. This paper presents a numerical simulation of multilayered geogrid-reinforced piled embankments. It shows that the inclusion of geogrids can effectively help transferring stress from subsoil to the pile cap, particularly for stiffer geogrids. Although the maximum settlement is approximately identical, an embankment with a three-layer geogrid provides more uniform stress distribution on the surface of subsoil and results in less differential settlement through the embankment. The maximum settlement and the total tension in the geogrid are found to be dependent only on the total stiffness provided and not on the number of geogrid layers. The parametric study shows that the combination of very soft subsoil and a geogrid with low stiffness results in relatively large settlement and may cause intolerable geogrid strain. The pile spacing is also found to be the most sensitive factor influencing the maximum settlement of the subsoil. Finally, an analytical method is assessed and shows reasonable agreement with the numerical results.

System usability scale evaluation of online banking services: A South African study
Authors: Mujinga Mathias , Eloff Mariki M. , Kroeze Jan H.
Published: March 2018

Online banking is a critical service offered by financial institutions to their clientele to facilitate easier and faster access to financial services and transactions. Banks currently spend huge amounts of money on development and maintenance of websites and backend systems that offer online banking facilities to clients. Here we address the effect of moderating factors on online banking usability assessment in South Africa. Using statistical analysis techniques that included t-tests, ANOVA and correlation, we investigated whether there are statistically significant mean differences in system usability scale (SUS) scores based on a variety of moderating factors in South Africa. Findings based on a sample of 540 respondents show that SUS scores differ significantly based on factors such as age, experience and income, whereas factors such as gender, use frequency and employment did not affect the mean SUS scores. Given the individual SUS scores for a variety of users based on different demographics, the financial institutions might improve service usability to target specific user groups and realise their return on investment in digital banking channels. Therefore improving service usability might go a long way in encouraging online banking adoption in South Africa.
Significance:

The overall assessment of online banking service by users based on a SUS measurement tool was investigated.
The effect of moderating variables on the mean SUS scores of different user groups was established.
An insight into areas of improvement with regard to usability based on demographic information of users is provided.
Temporal ranges and ancestry in the hominin fossil record: The case of Australopithecus sediba
Authors: Robinson Chris , Campbell Timothy L. , Cote Susanne , De Ruiter Darryl J.
Published: March 2018

In attempting to resolve the phylogenetic relationships of fossil taxa, researchers can use evidence from two sources – morphology and known temporal ranges. For most taxa, the available evidence is stronger for one of these data sources. We examined the limitations of temporal data for reconstructing hominin evolutionary relationships, specifically focusing on the hypothesised ancestor–descendant relationship between Australopithecus sediba and the genus Homo. Some have implied that because the only known specimens of A. sediba are dated to later than the earliest fossils attributed to Homo, the former species is precluded from being ancestral to the latter. However, A. sediba is currently known from one site dated to 1.98 Ma and, thus, its actual temporal range is unknown. Using data from the currently known temporal ranges of fossil hominin species, and incorporating dating error in the analysis, we estimate that the average hominin species’ temporal range is ~0.97 Myr, which is lower than most figures suggested for mammalian species generally. Using this conservative figure in a thought experiment in which the Malapa specimens are hypothesised to represent the last appearance date, the middle of the temporal range, and first appearance date for the species, the first appearance date of A. sediba would be 2.95, 2.47 and 1.98 Ma, respectively. As these scenarios are all equally plausible, and 2.95 Ma predates the earliest specimens that some have attributed to Homo, we cannot refute the hypothesis that the species A. sediba is ancestral to our genus based solely on currently available temporal data.
 Significance:

We correct a common misconception in palaeoanthropology that a species currently known only from later in time than another species cannot be ancestral to it.
On temporal grounds alone one cannot dismiss the possibility that A. sediba could be ancestral to the genus Homo.

Published: March 2018

La ciudad del Cusco, antigua capital de la civilización Inca, alberga por más de tres siglos a la Universidad Nacional San Antonio Abad del Cusco (UNSAAC). Estudiar las actitudes lingüísticas de los estudiantes universitarios hacia el quechua se hace necesario para entender el posible escenario para la mantención y recuperación del idioma quechua en el Cusco, en particular en la UNSAAC la cual tiene una creciente población estudiantes quechuahablante. En este artículo nos interesa explorar las actitudes lingüísticas de los estudiantes universitarios hacia el quechua por medio de una encuesta anónima no probabilística. Para el propósito de este articulo entendemos la actitud lingüística como la respuesta afectiva de los estudiantes de la UNSAAC hacia el idioma quechua. En el 2016 más de 300 estudiantes de la UNSAAC fueron encuestados para observar las actitudes lingüísticas hacia el quechua. La hipótesis que se logró comprobar fue la siguiente: Los estudiantes universitarios de la UNSAAC demuestran actitudes lingüísticas positivas hacia el quechua. A diferencia de la conclusión de Wolck sobre que la lengua quechua tiende a tener un alto valor positivo a nivel personal y no así un alto valor institucional instrumental (Wolck, 2003); los resultados de este estudio nos revelan la existencia del valor tanto personal e institucional del quechua adscrito por los estudiantes ya que sus actitudes lingüísticas son positivas hacia el quechua fuera y dentro de la universidad.

Published: March 2018

Los estudios universitarios no solamente significan para los jóvenes contemporáneos un proceso o etapa de formación profesional, sino también, un momento en sus vidas que les presentan diferentes retos que les exigen desarrollar competencias, tanto disciplinares, como sociales y personales. Lamentablemente, si el joven no consigue superar esta prueba, los problemas que trae consigo esta etapa lo superaran, eslabonándose en situaciones que sencillamente se verá incapaz de afrontar. Por ello, las universidades deben ver por herramientas pedagógicas que no solo vean por el desarrollo académico de sus estudiantes, sino también por la adopción de competencias de afrontamiento que les permitan mejorar como personas. El presente artículo, busca hacer una aproximación al mentoring, como posible herramienta de acompañamiento que de manera indirecta puede reducir la deserción escolar al mejorar la experiencia de aprendizaje de los estudiantes universitarios.

Published: March 2018

En el contexto socioeconómico de su época, Elena de White llamó a la agricultura el ABC del currículum para recalcar su importancia en la educación de una iglesia, además de actividades como la culinaria, confección, colportaje, entre otras. Todas ellas como acciones co-curriculares en contribución al desarrollo armonioso de las facultades humanas de las que los pensamientos modernos no necesariamente los contemplan. A partir de una investigación exploratoria pretendemos comparar las propuestas de las actividades co-curriculares en Elena White con la de autores contemporáneos. Los resultados indican que las actividades cocurriculares en Elena White, trasciende las propuestas contemporáneas porque prepara a los estudiantes física, social, espiritual e intelectualmente; en tanto que la propuesta contemporánea considera que las actividades cocurriculares son un apoyo fundamental para los estudiantes y sirven para ampliar sus niveles de conocimiento, investigación y currículo.

De la reflexión ideológica a la realidad pedagógica
Authors: D. Expósito Cristián
Published: March 2018

No es posible hablar de educación sin valores, como tampoco es posible hablar de cultura sin ideología. De la misma manera que los valores modelan y le dan sentido a la educación, las ideologías van dando forma a la cultura de los pueblos. Los valores son los responsables de las acciones de las personas, instituciones y sociedades, sin embargo, en base a las ideologías, éstos se ordenan. Es la ideología la que permite unir el entorno de la persona con su propia identidad, es el puente entre lo macro social y lo micro social; un concepto inconmensurable compuesto de valores personales, creencias y determinadas maneras de pensar que brindan una explicación del mundo en que vivimos. Los sistemas educativos de los países están reglamentados por una serie de principios axiológicos que responden a un modelo ideológico preponderante a nivel social. El peligro de estos modelos ideológicos subyace en el reduccionismo que puede llegar a sumir a una comunidad en algo menos que el oscurantismo. En este trabajo se explica la relación existente entre ideologías, valores, cultura y educación partiendo de las conceptualizaciones de las tres ideologías más influyentes en la educación latinoamericana: el cristianismo, el marxismo y el anarquismo.

O estudo da emissão de CO2 do solo em sistemas de manejo de cana-de-açúcar é um importante indicativo da qualidade do solo e um enfoque que pode elucidar a alguns questionamentos sobre a eficiência da conversão do sistema de cana queimada em cana crua. Baseado nisso, este trabalho teve como objetivo avaliar a variabilidade espacial da emissão de CO2 e macroporosidade do solo em sistemas de cana-de-açúcar com e sem queima. Nas áreas em estudo foi instalada uma malha amostral (100 x 100 m) com pontos espaçados em 1, 2 e 10 m. A avaliação de CO2 foi realizada nos pontos da malha amostral de forma simultânea, nas duas áreas, por 9 dias das 7:00 as 11:00 h, com auxílio de câmaras de solo (modelo LI-8100). Amostras indeformadas foram coletadas na camada superficial do solo (0,00-0,10 m) com auxílio de anéis volumétricos de kopeck para análises de densidade, macro e microporosidade do solo. A emissão de CO2 e macroporosidade do solo apresentaram tendências similares na análise descritiva e geoestatística, ou seja, pode-se concluir que a macroporosidade do solo influenciou a emissão de CO2 em sistemas de manejo de cana-de-açúcar.Palavras-chave: Variabilidade espacial, macroporosidade, respiração do solo, cana crua, Saccharum spp.  GEOSTATISTICAL ANALYSIS OF CO2 EMISSION AND MACROPOROSITY OF RED LATOSOL EUTROFERRIC UNDER SUGARCANE CULTIVATIONABSTRACT: Soil CO2 emission is an important soil quality indicator and an approach that can answer questions about the efficiency conversion from“burnt cane” to “green cane” systems. This work aimed to evaluate the spatial variability of CO2 emission and soil macroporosity attributes from sugarcane cultivation systems with and without burning. A sample grid (100 x 100 m) with points spaced at 1, 2 and 10 m was installed in experimental areas. CO2 evaluation was carried out at the all points grid in the both areas simultaneously, for 9 days, from 7:00 to 11:00 h, with soil chambers (model LI-8100). Undeformed soil samples were collected from superficial soil depth (0.00-0.10 m) using volumetric rings for soil bulk density, macro and microporosity analyzes. CO2 emission and macroporosity showed similar trends in descriptive and geostatistical analysis.  Therfore, it can be concluded that  soil macroporosity influenced  CO2 emission in sugarcane management systems.KEYWORDS: Geostatistic.

A coleta de dados ocorreu no período entre novembro de 2015 e março de 2016, no maior bairro da periferia de um município da região médio norte de Mato Grosso, mediante roteiro de observação, fotografias, fita métrica e diário de campo. As imagens foram interpretadas pela análise iconográfica. Resultados: o descuido e o desrespeito com as questões ética e ambiental de outros moradores ficaram evidentes no estudo, colaborando ou intensificando barreiras urbanísticas para inacessibilidades das pessoas com deficiência. Dentre as barreiras encontradas, predominou descontinuidade e empecilhos em calçadas. Conclusão: como forma de eliminar essas barreiras e promover maior inclusão social, fazem-se necessárias medidas de conscientização da população, práticas informativas sobre seus direitos e acolhimento integral, principalmente conduzidos por profissionais de saúde, além do olhar sensível dos órgãos gestores.

Accumulating evidence has shown that hypothyroidism affects the cardiovascular system, significantly increasing the incidence of cardiovascular diseases. In the present study we investigated the effect of radioactive iodine (I-131)-induced hypothyroidism on several parameters of vascular function, such as nitric oxide (NO), total nitric oxide synthase (NOS) activity and expression of NOS isoforms, as well as on interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) as indicators of inflammation, in rats. A dose of 150 µCi of 131-I was determined as optimal for establishing the model of hypothyroidism in rats. After administration of 131-I, at the end of month 1, 2, and 4 (n = 3 for each time point), NO, IL-6, and TNF-α in the serum and total NOS activity in the aorta were determined in 150 µCi group, compared to controls. The mRNA and protein expression of endothelial, neuronal, and inducible NOS (eNOS, nNOS, and iNOS) in the rat aorta was also estimated, using quantitative reverse transcription polymerase chain reaction and Western blot, respectively. The levels of IL-6 and TNF-α increased in 150 µCi group; the results were significant at the end of month 2 and 4 for IL-6, and at all time points for TNF-α. The levels of NO decreased significantly at the end of month 2 and 4 in 150 µCi group. The total NOS activity increased significantly in 150 µCi group, at all three time points. Significant changes in the mRNA and protein expression of all three NOS isoforms were observed in 150 µCi group compared to controls. NO, IL-6, TNF-α levels and NOS activity and expression are altered in hypothyroid state, and the underlying mechanism should be further investigated.

Очерчен круг проблем, не позволяющих в полной мере реализовать огромный потенциал применения фосфида индия и арсенида галлия в твердотельной электронике. Проанализированы и обобщены классические и современные результаты по термическому оксидированию полупроводников AIIIBV, в том числе со  стимуляцией процесса обработкой фотонами, магнитными импульсами и т.д. Особое внимание уделено рассмотрению  фундаментального подхода к решению проблемы формирования наноразмерных функциональных пленок на AIIIBV, заключающегося в использовании обоснованно выбранных хемостимуляторов, вводимых в систему различными способами с целью изменения механизма процесса термооксидирования полупроводников с собственного на хемостимулированный. Это обеспечивает протекание новых интерфейсных реакций с кинетически сопряженными и гетерогенно-каталитическими стадиями, что позволяет в едином процессе осуществить кинетический обход нежелательных стадий собственного оксидирования, снизить рабочие параметры (температура, время) процесса формирования пленок и одновременно управлять составом и свойствами функциональных пленок нанометрового диапазона толщины с достижением целевых характеристик.

Предложен расчетный способ оценки количества вещества адсорбата (N) и динамической емкости сорбента (Q) в условиях очистки от загрязнителей в потоке. Рассмотренные подходы действительны при использовании сорбентов и удалении сорбатов любой природы из проточных сред независимо от скорости потока элюата в условиях ламинарного течения жидкости.

Способ основан на использовании β-сплайновых кривых и базируется на свойствах геометрической непрерывности, используемых при решении задач геометрического моделирования посредством кубических многочленов. Он позволяет:

- рассчитать величины динамической емкости Q к любому моменту времени от начала сорбции при отсутствии экспериментальной оценки величины коэффициента сорбции ρτi;

- оценить рассчитанное время непрерывной работы сорбента до его замены или регенерации.

При комнатной температуре получены величины Qi глауконита по катионам Сu(II), Ni(II), Zn(II) при их совместной сорбции как функция природы адсорбата с учетом высоты его слоя, линейной скорости подачи раствора при произвольном интервале времени от начала процесса. Оценена относительная сорбционная способность катионов в зависимости от тех же факторов. Показано, что с ростом скорости подачи раствора увеличивается динамическая емкость сорбента, которая изменяется в ряду:

QNi(II) > QZn(II) > QСu(II)

Porcine circovirus type 2 (PCV2) is associated with distinct syndromes and diseases in swine, collectively known as porcine circovirus-associated diseases (PCVAD), which include postweaning multisystemic wasting syndrome (PMWS), PCV2-associated pneumonia as a part of the porcine respiratory disease complex (PRDC), PCV2-associated enteritis, PCV2-associated reproductive failure, and porcine dermatitis and nephropathy syndrome (PDNS) (1–3). PCV2-infection is widespread and essentially all pig herds are infected with PCV2. Porcine circovirus 2 (PCV2), a member of the genus Circovirus in the family Circoviridae, is a very small single-stranded negative-sense DNA virus of approximately 1.7 kb (4). The genome of PCV2 encodes three major open reading frames (ORFs) encoding the replicase proteins (ORF1), the viral capsid protein (ORF2), and a protein with suggested apoptotic activity (ORF3) (5). Previous reports showed that there were five PCV2 genotypes, including PCV2a, PCV2b, PCV2c, PCV2d, and PCV2e (6– 9). Here, we report the complete genome sequence of Ukrainian PCV2 isolates from different regions of Ukraine.

RESUMENIlustración y neoclasicismo hallan en el término «Razón» una de sus más firmes bases. La razón se convierte en norma y aspiración para buena parte de los intelectuales dieciochescos, haciéndose visible como ideal en obras de muy diversa índole. El sentimiento, por su parte, ha de ser pasado por el el tamiz de la razón. En este trabajo se analiza la manifestación de ambos integrantes del habitual binomio en las Obras de Garcilaso de la Vega, ilustradas con notas (Madrid, Imprenta Real de la Gaceta, 1765) por José Nicolás de Azara, edición que recuperó para las prensas la obra del poeta toledano tras una larga ausencia de las mismas, presentándolo como modelo del «buen gusto» en base a una estética neoclásica promovida bajo el reinado de Carlos III.PALABRAS CLAVERazón, sentimiento, Garcilaso, Azara, lírica, Siglo de Oro, Ilustración, neoclasicismo. ABSTRACTEnlightenment and Neoclassicism find in the term «Reason» one of their firmest bases. Reason becomes norm and aim for a great number of the XVIIIth Century intellectuals, becoming visible as ideal in works of various kinds. Feelings, on the other hand, must be passed through the sieve of reason. In this work, I analyse how both elements of the binomial manifest themselves within  Obras de Garcilaso de la Vega, ilustradas con notas (Madrid, Imprenta Real de la Gaceta, 1765) by José Nicolás de Azara, an edition which recovered for the printing presses the work of the poet from Toledo after a long absence from them, presenting it as a model of «buen gusto» according to a neoclassical aesthetics promoted under the reign of Carlos IIIKEYWORDSReason, feeling, Garcilaso, Azara, lyric, Golden Age, Enlightenment, Neoclassicism
