A volumetric ablation model of EPDM considering complex physicochemical process in porous structure of char layer
Authors: Yang Liu , Xiao-Jing Yu , Jian-Ming Ma , Yi-Wen Guan , Jiang Li , Qiang Li , Sa Yang
Published: June 2017

A volumetric ablation model for EPDM (ethylene- propylene-diene monomer) is established in this paper. This model considers the complex physicochemical process in the porous structure of a char layer. An ablation physics model based on a porous structure of a char layer and another model of heterogeneous volumetric ablation char layer physics are then built. In the model, porosity is used to describe the porous structure of a char layer. Gas diffusion and chemical reactions are introduced to the entire porous structure. Through detailed formation analysis, the causes of the compact or loose structure in the char layer and chemical vapor deposition (CVD) reaction between pyrolysis gas and char layer skeleton are introduced. The Arrhenius formula is adopted to determine the methods for calculating carbon deposition rate C which is the consumption rate caused by thermochemical reactions in the char layer, and porosity evolution. The critical porosity value is used as a criterion for char layer porous structure failure under gas flow and particle erosion. This critical porosity value is obtained by fitting experimental parameters and surface porosity of the char layer. Linear ablation and mass ablation rates are confirmed with the critical porosity value. Results of linear ablation and mass ablation rate calculations generally coincide with experimental results, suggesting that the ablation analysis proposed in this paper can accurately reflect practical situations and that the physics and mathematics models built are accurate and reasonable.
Preconcentration of nickel in waters by vortex assisted dispersive liquid-liquid microextraction
Authors: Sánchez-Rojas F. , Bosch-Ojeda C.
Published: June 2017

The present work describes the attempt for the preconcentration of nickel ions by using vortex assisted dispersive liquid-liquid microextraction from aqueous samples. In this method, a small amount of chloroform is rapidly injected by syringe into the water sample containing nickel ions complexed by diethyldithiocarbamate (DDTC).This forms a cloudy solution. The cloudy state is the result of chloroform fine droplets formation, which are dispersed in bulk aqueous sample. Therefore, Ni-DDTC complex is extracted into the fine chloroform droplets and vortex agitation takes place during six minutes. After optimization of experimental variables and determination of analytical characteristics, the method is evaluated for application in real samples. HPLC is used as separation and detection system.

Das gesellschaftlich verantwortliche Agieren von Genossenschaften als Komponente des Membership-Value
Authors: Rößl Dietmar
Published: June 2017

Cooperative banks do not easily generate immediate economic benefit for their members through business relations with them. They try to create meta-economic members’ benefits and to accomplish their mission by acting socially responsible, mostly with regional aspects. The question arises, whether members view these efforts as a part of their benefit. In this article, we answer this question by using a marketing oriented argumentation and an analysis of a cooperative which presents itself as socially responsible.
Zwischen Heteronomie und Autonomie
Authors: Grube Klemens
Published: June 2017

Nowadays, cooperative banks in Estonia and Latvia are a marginal phenomenon. During the both countries’ first autonomy and before, they figured prominently and were fixed firmly in all classes of population. There were three development phases. We conclude that genesis, prosperity and demise of cooperative banks are linked closely to the political and economic situation of the respective country. The development proceeded similarly in both countries, however the Latvian institutions performed more effectively.

Opinión pública e infoxicación en las redes: los fundamentos de la post-verdad
Authors: Niño González José Ignacio , Barquero Cabrero Mario , García García Enrique
Published: June 2017

“Post-verdad” es la palabra del año para el 2016 del diccionario Oxford, gracias a las nuevas tecnologías, y a la forma en la que la propaganda política –y la política misma- se ha estado sirviendo de ellas. Es una palabra que tiene connotación de falsedad consciente e inconsciente, de manipulación y de revisionismo de la realidad misma. En cierto modo, una evolución de lo que ha sido y es la publicidad y la propaganda históricamente, pero abriendo con su existencia el esencial debate de hasta qué punto la libertad de expresión protege la libertad para faltar a la verdad, y a las intenciones benignas o interesadas que puedan existir detrás de todo ello.
The Waning Effect of China’s Carrot and Stick Policies on Taiwanese People
Authors: Wang Austin Horng-En
Published: June 2017

To repress growing regional/national identity in Taiwan, China applies rationalist strategies, including economic incentives and military threats. Analysis of the Taiwan National Security Survey in 2003–2015 shows that China’s carrot and stick policies negatively correlate with exclusive Taiwanese identity. In younger generations, perception of the strength of the policies is similar, but their effect on identity is weaker.
“We Can Make Something Out of Anything”: Sally Potter's Thriller and London's History of Queer Feminist Film Spaces
Authors: Mayer Sophie , Robertson Selina
Published: June 2017

The National Trust, a British charity founded in 1895 that manages heritage buildings and open spaces for the UK, is now running daytime tours of London's queer club culture from 1918 to 1967 (when the Sexual Offences Act decriminalized private homosexual acts between men over the age of 21), ending at a version of the Caravan, a queer-friendly members' club from 1934 recreated from police records and court reports. Further, the queer activists Sexual Avengers marked 2017's LGBT History month by placing unofficial “Queer Heritage” blue plaques on London landmarks, including one that commemorated the 1988 action against Section 28 in which four lesbians rappelled into the second chamber of the UK Parliament, the House of Lords.

The fiftieth anniversary of the passing of the Sexual Offences Act is being marked this summer by programming at the British Film Institute and other UK cultural institutions. With the National Trust also showcasing the portrait of the Lord Orlando, it is a time when queer histories are clearly entering the mainstream curatorial and cultural spaces and interpretations, making 2017 a productive time to offer a thick description of the complexities of labor, politics, and creative practice that may be smoothed over by this move. At the same time, current queer and feminist spaces in London (as elsewhere in the overdeveloped world) are encountering a recapitulation and intensification of the 1970s version of austerity and precarity that formed both the pretext and subtext of Potter's first film, Thriller (1979), making it an ideal text through which to examine these issues.
A Sense of Place: Paz Encina's Radical Poetics
Authors: Brizuela Natalia
Published: June 2017

Paz Encina became a public figure in Paraguay after her first film, Hamaca Paraguaya (Paraguayan Hammock, 2006), won major awards and put Paraguayan cinema back on the international map for the first time in decades. In 2012, she was invited to “do something” visual with the Archivos del Terror (Archives of Terror) to mark the twentieth anniversary of the discovery of the heinous archives. Encina is not the only artist to make use of the Archives of Terror. Argentine Carlos Trilnick's Proyecto Archivos del Terror: Apuntes sobre el Plan Cóndor (Archives of Terror Project: Notes on the Condor Plan, 2013) also utilizes them. Natalia Brizuela posits that Paz Encina's use of the archival material from the Archives of Terror is different than Trilnick's. Her pieces demarcate specific spaces and insist on location, in contrast to Trilnick's work that is made to be packed up and reset in any space. Second, Encina's installations insist on disjointed forms of reenactment to establish a tension between embodiment of the spectator and disembodiment of the tortured bodies. She has since made three works that utilize the Archives of Terror. Her interest in the archival material never sought to generate a new archive but rather to engineer the spectatorial conditions for a site-specific experience. The fully embodied subject that emerged through the sound recordings became the motor for the work Encina produced on and around the Archives of Terror and the lengthy state-of-exception government that structured her country's life in the longest dictatorship to date in Latin America.
Digging and Bluing with Billy Woodberry
Authors: Luckett Josslyn
Published: June 2017

A long-view interview with filmmaker Billy Woodberry conducted by screenwriter and scholar Josslyn Luckett gives the filmmaker his due and reflects on his prolific career as an independent filmmaker. The unfolding of Billy Woodberry's career—both his own new work and the recent critical revaluations of his classic work, such as the naming of Bless Their Little Hearts (1983) to the National Film Registry in 2013—makes words like “rebellion” or “revival” only marginally useful. Any research into the full range of his film work, including his multiple roles as film actor, film narrator, video installation artist, and film history and production professor at California Institute of the Arts (CalArts) since 1989, reveals a Woodberry who might be more properly termed an underground “renaissance” man than a rebel.
Baldwin's Rendezvous with the Twenty-First Century: I Am Not Your Negro
Authors: Crichlow Warren
Published: June 2017

Thirty years after James Baldwin's untimely death at the age of 63, Haitian-born Raoul Peck makes good on Baldwin's spirited prophecy through his timely and intrepidly titled I Am Not Your Negro (2016). In his rendezvous with Baldwin, Peck carries Baldwin's prescient voice into the twenty-first century, where his rhetorical practice of “telling it like it is” resonates anew in this perilous political moment. Drawing on his signature practice of reanimating the archive through bricolage, Peck not only represents but also remobilizes Baldwin's image repertoire, helping to conjugate the very idea of this revered—and often criticized—novelist and essayist to renewed effect. Like audiences of an earlier era, today's viewers become spellbound by this critical witness's fervent idiomatic eloquence and uncompromising vision.

Crichlow argues that Baldwin's journey is palpably not over—perhaps just beginning. The film makes certain his illuminating prose and penetrating critique continue to assume new meanings in the present, which in turn creates new imaginaries for the future. I Am Not Your Negro augers a significant pedagogical intervention, set to revive knowledge of Baldwin through multifarious viewings, but equally to jump-start the art of reading in schools and communities where a new generation may have little access otherwise to Baldwin's texts. Baldwin had a prophetic sense of his “appointment with the twenty-first century.” In innumerable ways, Raoul Peck's superbly realized I Am Not Your Negro has helped him honor that date.

Published: June 2017

In agreement with students’ conceptual understanding, identifying of problem solving is an important part of physics. This article is to identify the approach used by students in solving a physics problem. The subject of the research were students of physics education year 2014 in Jambi University who had joined basic physics class. The instruments used in this research were DIRECT (determining and interpreting resistive electric circuit concept test) (Engelhardt & Beichner, 2004). Based on the result, 34,1% students still used the memory based approach in problem solving, 52,3% of them used no clear approach, 4,5% used structured manner, 6,82% used unstructured manner and only 2,27% students used a scientific approach to solving the problem. The result showed that many students used no clear approach and memory based approach to solve the problem. It mean that they did not use physics concept in solving the problem and generally they only used the equation they memorized related to the problem they ever did before.

Published: June 2017

A descriptive study of future teacher students’ mental models of essential concepts in Cell Biology was carried out through explanatory mixed-methods. Some students (n=40) of Biology Education Universitas Negeri Semarang were involved as the research subject. We used a diagnostic test, structured interview guides, and field notes to describe students’ mental model. In the early stage, we prepare a diagnostic test performed essential concepts of Cell Biology. Secondly, we define students’ mental models map based on their answers. Thirdly, we identify factors which affect students’ mental models. Exploration of mental models was conducted through structured interviews with students representing each category. The interview focused on reasoning and argumentation students’ abilities in answering the question on the test item. The research finding describes that students’ mental model in Cell Biology is grouped into three categories, macro-mental to think based of basic content, micro-mental in correlation of content, and intuitive-mental or misconception. This finding can be used in improving research-based learning in Cell Biology.

Published: June 2017

The study is aimed at finding an effective learning strategy that can increase metacognitive knowledge. Metacognitive knowledge is a standard that based on 2016-revised edition of 2013 curriculum needs to be achieved by every graduate in all level of education in Indonesia. The study is conducted in three different schools and engages 207 students, which then divided into six groups. The groups are students who study under mind mapping strategy, concept mapping, reciprocal teaching using summary notes, reciprocal teaching using mind mapping, problem-based learning, and investigation group. The results showed that those studying under problem-based learning strategy spent a significantly higher numbers in metacognitive knowledge in biology learning and followed by students who study under reciprocal teaching using mind mapping. According to the finding, it is expected that teachers of Biology will practice problem-based learning strategy in their classroom in order to increase the Metacognitive knowledge.
Effect of an obesogenic diet on circadian activity and serum hormones in old monkeys
Authors: Urbanski Henryk F , Mueller Kevin , Bethea Cynthia L
Published: June 2017

Like women, old female rhesus macaques undergo menopause and show many of the same age-associated changes, including perturbed activity/rest cycles and altered circulating levels of many hormones. Previous studies showed that administration of an estrogen agonist increased activity in female monkeys, that hormone therapy (HT) increased activity in postmenopausal women and that obesity decreased activity in women. The present study sought to determine if postmenopausal activity and circulating hormone levels also respond to HT when monkeys are fed a high-fat, high-sugar Western style diet (WSD). Old female rhesus macaques were ovo-hysterectomized (OvH) to induce surgical menopause and fed a WSD for 2 years. Half of the animals received estradiol-17β (E), beginning immediately after OvH, while the other half received placebo. Animals in both groups showed an increase in body weight and a decrease in overall activity levels. These changes were associated with a rise in both daytime and nocturnal serum leptin concentrations, but there was no change in serum concentrations of either cortisol or dehydroepiandrosterone sulfate (DHEAS). These data suggest that 2 years of HT has little or no effect on locomotor activity or circadian hormone patterns in menopausal macaques fed an obesogenic diet.
A rare case of an ACTH/CRH co-secreting midgut neuroendocrine tumor mimicking Cushing's disease

Published: June 2017

Ectopic ACTH/CRH co-secreting tumors are a very rare cause of Cushing’s syndrome and only a few cases have been reported in the literature. Differentiating between Cushing’s disease and ectopic Cushing’s syndrome may be particularly difficult if predominant ectopic CRH secretion leads to pituitary corticotroph hyperplasia that may mimic Cushing’s disease during dynamic testing with both dexamethasone and CRH as well as bilateral inferior petrosal sinus sampling (BIPSS). We present the case of a 24-year-old man diagnosed with ACTH-dependent Cushing’s syndrome caused by an ACTH/CRH co-secreting midgut NET. Both high-dose dexamethasone testing and BIPSS suggested Cushing’s disease. However, the clinical presentation with a rather rapid onset of cushingoid features, hyperpigmentation and hypokalemia led to the consideration of ectopic ACTH/CRH-secretion and prompted a further workup. Computed tomography (CT) of the abdomen revealed a cecal mass which was identified as a predominantly CRH-secreting neuroendocrine tumor. To the best of our knowledge, this is the first reported case of an ACTH/CRH co-secreting tumor of the cecum presenting with biochemical features suggestive of Cushing’s disease.

Learning points:

The discrimination between a Cushing’s disease and ectopic Cushing’s syndrome is challenging and has many caveats.

Ectopic ACTH/CRH co-secreting tumors are very rare.

Dynamic tests as well as BIPSS may be compatible with Cushing’s disease in ectopic CRH-secretion.

High levels of CRH may induce hyperplasia of the corticotroph cells in the pituitary. This could be the cause of a preserved pituitary response to dexamethasone and CRH.

Clinical features of ACTH-dependent hypercortisolism with rapid development of Cushing’s syndrome, hyperpigmentation, high circulating levels of cortisol with associated hypokalemia, peripheral edema and proximal myopathy should be a warning flag of ectopic Cushing’s syndrome and lead to further investigations.

Published: June 2017

Epilepsy has many causes and comorbidities affecting as many as 4% of people in their lifetime. Both idiopathic and symptomatic epilepsies are highly heritable, but genetic factors are difficult to characterize among humans due to complex disease etiologies. Rodent genetic studies have been critical to the discovery of seizure susceptibility loci, including Kcnj10 mutations identified in both mouse and human cohorts. However, genetic analyses of epilepsy phenotypes in mice to date have been carried out as acute studies in seizure-naive animals or in Mendelian models of epilepsy, while humans with epilepsy have a history of recurrent seizures that also modify brain physiology. We have applied a repeated seizure model to a genetic reference population, following seizure susceptibility over a 36-d period. Initial differences in generalized seizure threshold among the Hybrid Mouse Diversity Panel (HMDP) were associated with a well-characterized seizure susceptibility locus found in mice: Seizure susceptibility 1. Remarkably, Szs1 influence diminished as subsequent induced seizures had diminishing latencies in certain HMDP strains. Administration of eight seizures, followed by an incubation period and an induced retest seizure, revealed novel associations within the calmodulin-binding transcription activator 1, Camta1. Using systems genetics, we have identified four candidate genes that are differentially expressed between seizure-sensitive and -resistant strains close to our novel Epileptogenesis susceptibility factor 1 (Esf1) locus that may act individually or as a coordinated response to the neuronal stress of seizures.
A Genetic Screen Reveals an Unexpected Role for Yorkie Signaling in JAK/STAT-Dependent Hematopoietic Malignancies inDrosophila melanogaster
Authors: Anderson Abigail M , Bailetti Alessandro A , Rodkin Elizabeth , De Atish , Bach Erika A
Published: June 2017

A gain-of-function mutation in the tyrosine kinase JAK2 (JAK2V617F) causes human myeloproliferative neoplasms (MPNs). These patients present with high numbers of myeloid lineage cells and have numerous complications. Since current MPN therapies are not curative, there is a need to find new regulators and targets of Janus kinase/Signal transducer and activator of transcription (JAK/STAT) signaling that may represent additional clinical interventions . Drosophila melanogaster offers a low complexity model to study MPNs as JAK/STAT signaling is simplified with only one JAK [Hopscotch (Hop)] and one STAT (Stat92E). hopTumorous-lethal(Tum-l) is a gain-of-function mutation that causes dramatic expansion of myeloid cells, which then form lethal melanotic tumors. Through an F1 deficiency (Df) screen, we identified 11 suppressors and 35 enhancers of melanotic tumors in hopTum-l animals. Dfs that uncover the Hippo (Hpo) pathway genes expanded (ex) and warts (wts) strongly enhanced the hopTum-l tumor burden, as did mutations in ex, wts, and other Hpo pathway genes. Target genes of the Hpo pathway effector Yorkie (Yki) were significantly upregulated in hopTum-l blood cells, indicating that Yki signaling was increased. Ectopic hematopoietic activation of Yki in otherwise wild-type animals increased hemocyte proliferation but did not induce melanotic tumors. However, hematopoietic depletion of Yki significantly reduced the hopTum-l tumor burden, demonstrating that Yki is required for melanotic tumors in this background. These results support a model in which elevated Yki signaling increases the number of hemocytes, which become melanotic tumors as a result of elevated JAK/STAT signaling.

Published: June 2017

Cereals form an indispensable part of the human diet, and wheat is one of the most important agricultural commodities worldwide. Technological quality of wheat grain is determined mainly by the representation of gluten proteins. The aim of this work was to evaluate the technological quality of winter wheat grain based on genetic markers rested on polymorphism of storage proteins. We analyzed ten varieties of winter wheat (Triticum aestivum L.), in which we determined the content of crude proteins and fractional composition of proteins. Then we analyzed the samples by electrophoretic methods using SDS – PAGE and A – PAGE protocols, which allowed us to separate storage proteins and subsequently to detect the presence of individual HMW-GS as molecular markers of breadmaking quality of wheat. We calculated Glu-score based on the representation of HMW-GS. According to SDS – PAGE, the most common composition of HMW-GS was formed by alleles 0, 7+9, 5+10, which occurred in 30 % of analyzed varieties (Natanael, Silvanus, Genoveva). The highest Glu-score (10) was achieved by the variety Ilias. From fingerprinting of gliadins in A - PAGE we constructed a dendrogram of relatedness of individual analyzed varieties. In dendrogram, most genetically distant varieties according to gliadins polymorphism are the varieties Silvanus from the varieties Bardotka, Sophytra, Faustina and Genoveva; also Natanael from the variety Sophytra. Genetically closest from this point of view is the variety Federer to the variety Panonnicus, as well as Natanael to Silvanus.

Published: June 2017

The effect of using soy milk and ABT culture on various Labneh properties was investigated. Six treatments of Labneh were made from soy and buffalo milk and from their mixtures using classic and ABT-5 starters. Labneh made from soy milk had the lowest yield, acidity, redox potential (Eh), total solids (TS), fat, ash, TN, TVFA, saturated fatty acids (SFA), monounsaturated fatty acids (MUSFA), and total amino acids contents while buffalo’s milk Labneh had the highest. Soy milk Labneh had the highest level of unsaturated fatty acids (USFA), polyunsaturated fatty acids (PUSFA) and linoleic acid and α-linolenic acid. Also, soy milk Labneh had the greatest count of Str. thermophillus, L. acidophilus and bifidobacteria. Utilization of soy milk only or mixed with buffalo milk in Labneh manufacture decreased the count of L. bulgaricus. Mixing of buffalo milk with soy milk increased the sensory evaluation scores of Labneh. Classic starter Labneh had higher values of yield, acidity, WSN, TVFA, SFA and lower values of pH than those of ABT Labneh. Using of ABT culture in Labneh manufacturing increased USFA and total free amino acids contents. ABT Labneh had higher numbers of Str. thermophillus than those of classic starter.

This study was conducted to investigate the presence of Enterococcus spp. in meat, meat products and seafood. A hundred and four samples were randomly collected from different geographic localities in Libya. The samples were subjected to microbiological analysis for enumeration and isolation of Enterococcus spp. by conventional cultural and molecular identification using PCR and partial sequencing of 16S rDNA techniques. Out of 104 samples, 73 (70.2%) isolates were found to be enterococci based on their cultural characteristics on ESD medium. However, out of 36 samples subjected to molecular identification, only six isolates were confirmed to be Enterococcus spp. using PCR and partial sequencing of 16S rDNA technique. All enterococci strains tested for their antibiotic sensitivity profiles showed high percentage of multi-resistance phenotype. These results can be used for further studies on enterococci as an emerging food borne pathogen and its role in human infection in Libya and would suggest that meat, meat products and seafood might play a role in the spreading of enterococci through the food chain with antimicrobial resistance characteristics.

Published: June 2017

The impact of added pumpkin flour (1–10 g/100 g) on sensory and textural quality of rice bread was studied on rice biologically leavened rice bread. Specific volume, baking loss, crumb springiness, cohesiveness and resilience decreased with increasing amount of pumpkin flour. The opposite trend was found in crumb hardness and chewiness. Color measurements revealed that the lightness decreased and the greenness increased with increasing amount of pumpkin flour. Bread crumb and crust characteristics were not significantly impacted by the amount of added pumpkin flour. Additionally, the bread taste and flavor were decreased in breads with 8–10 g/100 g of added pumpkin flour, resulting in their lower overall acceptability. Weak impact of added pumpkin flour on sensory evaluation of rice bread may be related to a reduced amount of the panelists involved in this study. The addition of 1–7 g/100 g of pumpkin flour seems to be applicable to rice bread production. More extensive study will, however, be performed to describe the impact of added pumpkin flour on sensory quality of rice bread in more details.

Fermentation was carried out using Saccharomyces cerevisiae at room temperature. Fixed acidity estimated in terms of tartaric acid equivalent was determined in the range of 4.2 to 6.9g/L. Radical scavenging activity of the fermented juice was between the range of 1.42 to 1.96 mmol TE/L. Metals such as Cd, Cu, Mn, Ni, Pb and Zn were estimated. Residual sugar was within 3mg/ml. Ethanol concentration was estimated in the range of 5.25 to 10.67% (v/v).

Transcriptome analysis of chili and bell pepper samples from commercial plots in the municipalities of Santa Fe de Antioquia and El Peñol in the province of Antioquia revealed the presence of viral sequences with significant similarity to genomes of members of the genus Endornavirus. Assembly of the chili and bell pepper transcriptomes resulted in consensus sequences of 14,727 nt and 14,714 nt that were identified as Bell pepper endornavirus (BPEV). Both sequences were nearly identical by 99.9 % at both nucleotide and amino acid levels. The presence of BPEV was confirmed by RT-qPCR, RT-PCR and Sanger sequencing using RdRp-specific primers designed from the assembled sequences in ten independent random samples taken from the investigated bell pepper stands. The phylogenetic analysis of both BPEV variants and their affiliation within the genus Endornavirus is discussed. For our knowledge, this is the first study on this group of viruses in Colombia.

The relationship between tuber growth and demand for NPK in andigena group of potato (Solanum tuberosum L. ssp. andigena) is poorly documented under conditions of the Andean region of Colombia. It is necessary to establish a specific nutrient management for high yields to changes in edaphic-environmental supply and improve the production of Capiro and Supreme cultivars. Twelve treatments were evaluated at different stages (75-100-125-150 days after planting) of tuber growth using a repeated measures design with three factors: two cultivars (Capiro, Suprema); three locations with contrasting soils (Subachoque, Facatativá, and Choconta) and two levels of fertilization, F0 (unfertilized) and F1 (fertilized) of incomplete nature by differential fertilization by soil type. A positive correlation between fresh weight, dry weight and extraction of N, P and K (kg ha-1) by the tubers, beside harvest extraction index (HEI) was determined. Under optimal conditions of fertilization significant differences (P<0.001) between factor interactions cultivar x phenology x location for accumulation of N and P were detected, where Suprema was less demanding in the HEI of N (1,92 kg t-1 harvest) and HEI of P (0.38 kg t-1 harvest) than Capiro and was better adapted to acid soils of low fertility, in contrast the HEI of K Between 5.28 and 5.34 kg t-1 harvest did not show differences between cultivars due to the genotypic characteristics in the accumulation of dry biomass and starch that make them suitable for industrial use, in addition it was verified that the nutritional extraction depends on the genetic potential determined by the interaction with the environmental and edaphic supply.

Published: June 2017

Cavendishia bracteata and Thibaudia floribunda (Ericaceae) are wild fruit shrubs native to the Andes region. This study aimed to characterize the rooting potential of basal and apical cuttings using naphthalene acetic acid (NAA) in different concentrations (0, 200, 500, or 1,000 mg L-1). In C. bracteata, the cutting position on the branch affected its sprouting and rooting, with apical cuttings presenting the best performance with auxin application. The rooting of cuttings was more successful in C. bracteata than in T. floribunda. NAA applications between 200 to 500 mg L-1 were more suitable for the propagation of C. bracteata due to the higher percentages of rooting and shoot production. For propagation of T. floribunda, the use of apical cuttings without the application of auxins is recommended. Adventitious roots in cuttings of both species were originated from parenchyma cells of the stem.

Published: June 2017

Se caracterizó detalladamente un Andisol derivado de ceniza volcánica de la cuenca alta de la quebrada Santa Elena, Oriente Antioqueño (Colombia), con el fin de realizar en él otros estudios más detallados de pedogénesis. El suelo estudiado presentó un bajo contenido de bases y de fósforo disponible y una alta acidez, lo que indica un bajo nivel de fertilidad natural. El alto contenido de materia orgánica superficial está en concordancia con el clima frío húmedo de la zona y con la formación de complejos organometálicos que la protegen de la mineralización. Los horizontes superficiales del perfil estudiado se clasificaron como no alofánicos mientras que los horizontes subsuperficiales se clasificaron como alofánicos. El suelo estudiado mostró evidencias de ser poligenético, así como de fenómenos de erosión asociados a cambios climáticos drásticos y fue clasificado como un Acrudoxic Fulvudand, medial, mezclado, isotérmico.

Published: June 2017

En este trabajo se aborda el problema de un flujo bifásico, el cual consiste de la interacción de fluido con partículas sólidas inmersas en él, debido a la dificultad teórica que aparece al calcular todos los esfuerzos provenientes de la interacción entre fluido-sólido o sólido-sólido, así como las condiciones de contorno; se propone un enfoque numérico en el que se simula el movimiento fundamentado en las ecuaciones macroscópicas tanto para el fluido como para las partículas sólidas. Se creó un compendio de programas en ROOT que solucionan las ecuaciones de Navier-Stokes que describen la fase líquida usando el método de elemento finito, y para las partículas se usa un método explícito que soluciona las ecuaciones de movimiento de Newton, en donde conforme se realiza un paso en el tiempo las posiciones de los sólidos y el campo de velocidades son calculadas iterativamente. La simulación numérica permite investigar la dinámica del sistema, y calcular tanto el movimiento de las partículas como el del fluido en cuestión, obteniendo de esta manera importantes características en el estudio de los flujos bifásicos, las cuales son contrastadas con resultados experimentales.
Construcción de un escáner tridimensional usando C++ y hardware libre
Authors: Gamboa Cristian Enrique , Sanchez Carlos William
Published: June 2017

En este trabajo, se desarrolló un sistema económico de escaneo tridimensional (3D) que permite obtener información de la estructura física de un determinado objeto a partir de la cual, se genera un modelo digital. Este sistema opera proyectando un haz de luz láser en forma de línea sobre el objeto, mientras rota sobre su propio eje (eje z), el haz de luz crea un perfil del objeto, el cual es capturado mediante vídeo de alta definición (HD) por una cámara. A través del procesamiento digital de las imágenes capturadas se obtienen los vértices del objeto y se construye el modelo tridimensional. Para llevar a cabo esta tarea, el escáner 3D está formado por un conjunto de elementos de hardware y software libre como lo son: la plataforma Arduino, que permite realizar el control del hardware de escaneo, y un software desarrollado en C++ que implementando las librerías OpenCv y OpenGl, permite la realización de las tareas de procesamiento y análisis de imágenes. Estos elementos hacen que este desarrollo, se  constituya como incursión económica en la tecnología de escaneo laser tridimensional.

En el presente trabajo se reporta el estudio de las propiedades estructurales y magnéticas de la composición en forma de polvo de Gd0.257-xTbxFe0.743 con x=0,  0.1285,  0.257,preparados por Aleamiento Mecánico (AM) en atmosfera de argón durante 72 horas mediante un molino planetario de alta energía ;la caracterización estructural se realizó por medio de Difractometría de rayos X(DRX), para la caracterización magnética se utilizó la espectroscopía Mössbauer, los ciclos de histéresis se llevaron a cabo a través de  PPMS (Physical Property Measurement System), Sistema de Medidas de Propiedades Físicas.La fase de α-Fe se presenta en los tres difractogramas mediante un pico característico cuya  intensidad disminuye al reemplazar el Tb por el Gd, presentándose la menor en x= 0 así mismo se observa un aumento de su ancho atribuible a la presencia de átomos de Gd en lugares propios del Fe. Los espectros Mössbauer (EM) fueron ajustados con sextetos, dobletes, singletes y distribuciones de campo hiperfino lo que señala que el orden magnético se ve alterado al sustituir el Tb por el Gd en la composición. Las propiedades magnéticas extrínsecas de la composición en estudio, la caracterizan como materiales magnéticamente semiduros.

Absztrakt

Bevezetés: A Poupart-szalag fascia lata felhasználásával végzett
rekonstrukcióját ismertetjük. Esetismertetés: Egy 66 éves
nőbeteg esetét ismertetjük, akinek anamnézisében kizáródott lágyéksérv műtétje
kapcsán szerzett vena femoralis sérülés miatti érsebészeti beavatkozás, majd
többszöri rekonstrukciós műtétek szerepelnek. A Poupart-szalag helyreállításakor
a fascia lata egy 15 × 3 cm-es csíkját használtuk, amit a spina iliaca anterior
superiorra nyeleztünk. Ezt transzponáltuk subcutan tunnelen és varrtuk a
tuberculum pubicumhoz, fedve így az iliacalis ereket. A hasfal
musculoaponeuroticus részét szabott, 15 × 13 cm-es polipropilén hálóval
rekonstruáltuk, amelyet subfascialisan a hasfal izomrétegéhez és a
„neo-Poupart-szalaghoz” varrtunk. Megbeszélés: A Poupart-szalag
teljes destrukciója ritka, de többszöri műtétet vagy traumát követően
kialakulhat. A szalag rekonstrukciójában csak szintetikus háló használata volt
ismert. Egy publikáció született autológ szövet és polipropilén háló
használatával végzett rekonstrukcióról. Az általunk ismertetett műtéti technika
ennek módosítása és első a hazai szakirodalomban.
Következtetés: Ez az új technika hasznos eszköze lehet mind
a plasztikai, mind a sérvsebészettel foglalkozó általános sebészek
armamentáriumának.
