Este artículo explora las complejidades del reclamo de derechos de autor para las obras de danza, lo cual no es tan sencillo como para otras formas artísticas. A pesar de estos desafíos, la proliferación de las redes sociales y las tecnologías de internet en las últimas décadas ha mejorado significativamente la capacidad de identificar a los creadores originales de obras de danza y hacer cumplir sus derechos, especialmente cuando estas obras se vuelven virales. El artículo examina las condiciones bajo las cuales los movimientos de danza y las obras coreográficas son consideradas susceptibles de protección por derechos de autor y evalúa el éxito de los esfuerzos de protección en diferentes sistemas legales. El análisis busca aclarar el panorama legal en torno a la protección de las obras de danza y las implicaciones para los creadores en la era digital.

La idiomaticidad, en materia fraseológica, es un rasgo que suele ir representado junto al concepto de motivación y se explica según el tipo de unidad fraseológica (UF) o de los constituyentes que la forman. La motivación, por su parte, se vincula a los procesos cognitivos existentes entre significado literal (SL) y significado figurado (SF) de la UF en cuestión. Partiendo de estas premisas, en el presente estudio se hace referencia al componente idiomático presente en la traducción fraseológica y se propone como objetivo determinarlo mediante un ejercicio de traducción de locuciones idiomáticas (L) destinado a estudiantes rusos, de cara a examinar el grado de idiomaticidad y motivación de las UF. Asimismo, se hace hincapié en la importancia de estas propiedades en la formación de traductores e intérpretes, así como en la adquisición fraseológica de estas unidades idiomáticas para una mayor competencia y destreza lingüística en general.

Introduction: The Sacroiliac joint (SIJ) serves as a crucial connection between the sacrum and ilium, playing a vital role in transferring forces during physical activity. Its biomechanical function is essential for stability, supported by ligaments and pelvic floor muscles. However, SIJ dysfunction can contribute to lower back pain, a condition affecting 70-85 % of Western society. Causes: SIJ dysfunction can stem from various factors, including abnormal motion or malalignment, triggered by arthritis, trauma, or atypical gait patterns. Diagnosis: Diagnosis SIJ dysfunction involves physical examinations such as FABER, compression, distraction, thigh thrust, and Gaenslen tests. Typically, three positive provocative test results are required for diagnosis, supplemented by imaging techniques like X-rays, MRIs, and joint injections. Misdiagnosis: Despite the availability of diagnostic methods, SIJ dysfunction is frequently misdiagnosed due to symptoms overlap with other conditions and overlooked etiology. Treatment: Upon diagnosis, SIJ dysfunction can be managed with conservative measures like physical therapy and NSAIDs, or more invasive interventions such as surgery. Conclusion: SIJ dysfunction is a prevalent yet often misdiagnosed condition, emphasizing the importance of raising awareness among both the public and clinicians to ensure accurate diagnosis and appropriate treatment.

El artículo examina las nociones de salud y enfermedad elaboradas por los planteamientos de G. Canguilhem. Estas son analizadas tomando en cuenta las hipótesis freudianas relativas a la neurosis, la normalidad y la enfermedad mental. En particular, se aborda el concepto de normatividad en la filosofía de G. Canguilhem, estableciendo un diálogo con las nociones de síntoma y enfermedad en los textos freudianos. En este marco, se da relevancia a la relación entre el síntoma y la fantasía como fenómenos que resaltan la creatividad del ser viviente. Se precisa que esta última se expresa de modo diferenciado en la organización de los cuadros neuróticos y psicóticos. Para finalizar, a través de las ideas expuestas por A. Badiou, se analiza la tensión entre la dimensión objetiva y subjetiva del sujeto, como sustrato lógico de la crítica que puede ser establecida de los procedimientos científico-naturales de la medicina y su afán de objetivación de la experiencia clínica.

Introduction: atlas assimilation can occur alone or in association with other craniocervical junction malformations and deformities. The etiological and pathological mechanisms are not clear. Case presentation: patient in her sixth decade of life, who was treated at the «Eugenio Espejo» Hospital, with asymmetric pyramidal symptoms after a low-energy kinetic fall. The condition completely reverted with conservative management. The patient is currently under periodic observation. Conclusion: the atlas assimilation, a congenital malformation, often asymptomatic; it is part of an embryological compensation when it is associated with other malformations. The appearance of deformity is necessary to reach atlantoaxial instability that it is not early. The knowledge of the concepts and distinction of the craniocervical junction abnormalities allows to indicate the best treatment in order to obtain the most suitable results with the individualization of each case.

Corpse's putrefaction is caused by the action of bacteria, fungus, heat and humidity. To prevent the corpse from being destroyed, it is necessary to perform some procedures on it that modify the physical and chemical properties of the organic matter through different means. The cadaveric preservation processes are mainly caused by the exposition to external natural factors of time, mode and place, or to chemical factors injected. Many of the used formulas have always been jealously guarded and transmitted orally to selected groups. This tradition continues nowadays. The development of scientific knowledge boosted the register and diffusion of the current preservation techniques. This work proposes to put on paper the teachings of the master of anatomy, Professor Rodolfo Manuel Lafalla (†), about compiling preservation techniques without formaldehyde that were taught to him and transmitted throughout time in informal registers.

Mucho se ha cuestionado hasta el momento sobre la fraseología española en diferentes aspectos: sus límites de terminología, taxonomía, rasgos y su contexto general dentro de la lingüística. Al respecto, nos llamó la atención la existencia de algunas unidades agramaticales del tipo a ojos vistas y a pie juntillas. Como resultado, la agramaticalidad aparente que vamos a ofrecer es motivada por la fijación, uno de los rasgos de la fraseología y, a la vez, es distinguida como una propiedad de la fraseología española.

This study aims at examining the three commonest thesis in paremiology, namely the antiquity of proverbs, their popular origin and their belonging to the category of idiomatic expressions. Based on both diachronic and synchronic data and through an examination of the syntactic, semantic and metric structures of proverbs, the study brings out the misdirection of such vulgatas, and suggests a new approach, mainly based on the concept of lexical schemata, with an emphasis on the importance of metric patterns within the process of creation and evolution of paroemias.

Numerosos trabajos de investigación han señalado que la principal característica de las Unidades fraseológicas (UF) residía en su fijación. Por otro lado, la mayoría de los estudios fraseológicos en español han tratado las UF del español peninsular y a menudo común (EspPC). En este trabajo, analizamos el fenómeno tipológico y cuantitativo de la variación fraseológica en las llamadas construcciones verbales fijas (CVF) en español hispanoamericano (EspHisp). Para ello, se realiza una comparación de los diferentes tipos de variantes fraseológicas, en las dos orillas del atlántico a partir del análisis de una base de Datos de 41.000 CVF, de las que 26.000 pertenecen al EsPC y 15.000 al EspHisp. El análisis de centenares de ejemplos muestra que las CVF del EspHisp siguen los mismos patrones de formación que las del EspPC. También tratamos otro fenómeno de variación, en este caso significacional cuya frecuencia y complejidad requieren también de bases de datos exhaustivas para permitir a los usuarios descifrar los diferentes significados que complican su comprensión.

Introducción: El tratamiento de las fracturas de muñeca con placas volares bloqueadas puede ser insuficiente para las fracturas con fragmentos volares marginales distales a la línea de inserción distal del pronador cuadrado, sitio de inserción de importantes ligamentos. Objetivo: Evaluar la reproducibilidad de la técnica y los resultados del tratamiento de fracturas marginales volares de radio distal con clavijas, capturando el fragmento volar y dejándolas debajo de la placa volar bloqueada de radio distal. Materiales y Métodos: La técnica quirúrgica utiliza una o varias clavijas para fijar el fragmento volar semilunar del radio distal, bloqueándolas debajo de la placa. Inicialmente efectuamos una simulación cadavérica. Luego, realizamos un estudio retrospectivo que incluyó a 7 pacientes con fracturas de radio distal intrarticular con un fragmento marginal volar distal a la línea de la orilla, tratados entre septiembre de 2014 y febrero de 2015. El promedio de edad era de 53 años, y el del seguimiento, de 16 meses. Se obtuvieron radiografías en sucesivos controles. Al alta se evaluaron el rango de movilidad, la fuerza de prensión y dos puntajes funcionales. Resultados: Todas las fracturas consolidaron satisfactoriamente manteniendo la reducción del fragmento marginal volar. No hubo casos con inestabilidad radiocubital inferior como secuela. Conclusión: La fijación adicional del fragmento marginal volar lunar del radio con clavijas dobladas por debajo de la placa ofrece una alternativa de estabilización sencilla, económica y adecuada para suplir la fijación de un fragmento que la placa sola no estabilizaría adecuadamente. Nivel de Evidencia: IV

Objective: The FNS System DePuy Synthes® (EEUU, 2018) represents a recent alternative treatment for the fixation of femoral neck fractures, providing biomechanical advantages with respect to cannulated screws (3 CS). The objective of this study is to compare the clinical results of both fixation methods., Method: A retrospective collection of the 36 subcapital fractures treated with the FNS system was carried out compared with a retrospective search of the last 35 patients treated with 3 CS. Age, sex, fracture pattern, delay until the intervention, length of intervention, hospital length stay, and haemoglobin loss were analyzed. In addition, the rate of avascular necrosis, nonunion, symptomatic femoral neck shortening, and material protrusion with or without its removal were recorded during a minimum follow-up of 6 months., Results: No significant differences were found in age (p-value 0.32), fracture patterns (p-value 0.77), surgical delay (p-value 0.28), surgical time (p-value 0.226), length of hospital stay (p-value 0.921) and blood loss (p-value 0.086) between the two groups. A significantly higher overall complication rate was observed in the group treated with cannulated screws (p-value 0.004). Analysed separately, a higher rate of avascular necrosis, symptomatic shortening of the femoral neck, protrusion of the osteosynthesis material with or without removal was observed in the group treated with cannulated screws., Conclusions: The FNS system represents a safe and reproductible alternative for the fixation of femoral neck fractures, showing non-inferior outcomes to treatment with cannulated screws., (Copyright © 2024 SECOT.

Introduction: Supracondylar fractures of humerus are the second most frequent type of fractures in children. Objective: To describe the results of the treatment, the patients according to age, sex, complications, and final results. Material and methods: A retrospective descriptive study was conducted in patients with supracondylar fractures of humerus during the years 2018-2019. Absolute frequencies and percentages were calculated. Results: Fractures were more frequent in males (69.6%) and in the age group of six to 10 years for both sexes. 60.8% of the fractures were treated with reduction plus internal fixation with Kirschner needles, in the group with internal fixation type IV predominates and in the group that does not need internal fixation predominate type I, the most frequent complication was the loss of reduction in the group that was not fixed with needles. Better results were obtained when the reduction was performed combined with internal fixation (91.2%). Conclusions: Fractures predominated in the male sex and in the age group of six to 10 years, the reduction was more frequent more internal fixation with Kirschner needles, in the group with internal fixation predominates type IV, predominated the loss of reduction in the group that was not fixed with needles. Better results were obtained when reduction was performed combined with internal fixation. [ABSTRACT FROM AUTHOR]

Resumen: El análisis aquí propuesto sobre la variabilidad verbo-temporal en el uso de las construcciones fraseológicas (CFs), fundamentado en los campos teóricos de la Fraseología, de la Gramática del uso y de la Lingüística Cognitiva, tiene como objetivo central poner en discusión el criterio de la fijación, reconocido en el campo teórico de la Fraseología como un nivel de estabilidad al cual se vincula la propiedad de la idiomaticidad. Para tanto, se emprende un estudio basado en corpus para el análisis de la frecuencia de uso de las CFs tirar la toalla, poner el grito en el cielo y echar leña al fuego. Los datos analizados a partir del tratamiento estadístico aplicado por el Programa RStudio respaldan los argumentos a favor de la variabilidad en detrimento de la fijación, puesto que el núcleo verbal de las tres CFs puede aparecer conjugado en diferentes tiempos y modo verbales. Palabras Clave: construcciones fraseológicas; fijación; variabilidad morfológica. Abstract: The analysis proposed here about the verb-temporal variability in the use of phraseological constructions (CFs), based on the theoretical fields of the Phraseology, used-based theory of grammar and Cognitive Linguistics, has as a central objective to discuss the criterion of fixation, recognized in the theoretical field of Phraseology as a level of stability to which the property of idiomaticity is linked. Therefore, a corpus-based study is undertaken to analyze the frequency of use of CFs tirar la tolla, poner el grito en el cielo and echar leña al fuego. The data analyzed from the statistical treatment applied by the RStudio Program support the arguments in favor of the variability to the detriment of the fixation, since the verbal core of the three CFs can appear conjugated in different times and verbal mode. Keywords: phraseological constructions; fixation; morphological variability.

El divorcio contencioso influye en la fijación de las pensiones alimenticias a favor de los niños, niñas y adolescentes en la sociedad ecuatoriana, es un problema que atenta contra el derecho superior del niño/a y adolescente. El presente trabajo investigativo tiene como objetivo general estudiar las causas que ocasionan que no se fije una pensión alimenticia provisional a favor de los niños, niñas y adolescentes, en la Ciudad de Machala, durante el año 2017. La metodología utilizada es la teórica a través del análisis histórico y empírica a través de encuestas. Llegándose a la conclusión que en el juicio de divorcio contencioso no se fija una pensión alimenticia provisional a favor de los niños niñas y adolescentes porque la ley no lo dispone; por tratarse de un proceso civil no toma prioridad el interés superior del niño, el proceso puede durar hasta dos años, dependiendo de la causales y de las partes litigantes, ocasionando que los hijos habidos dentro del matrimonio no perciban pensión alguna mientras dure el juicio de divorcio.

Introduction: Plastination has been shown as a revolutionary and innovative technique in the field of conservation of anatomical pieces created by Gunther Von Hagens. Taking into account that the study of anatomy is currently based on the conservation and study of cadavers and anatomical specimens that are increasingly difficult to acquire and that allow a clear learning being useful for the training of undergraduate, graduate and professional exercise students and that can be preserved over time despite their continuous manipulation; it also allows to minimize biological risks for those in the area of health who are in the field of morphological sciences. In this way the anatomical details that in practice with corpses that are in preservation with formalin are lost, destroyed or difficult to visualize will be optimized and maintained. Objectives: Standardize an economic technique of plastination for the didactic study of morphology, through the use of polyester resins in organs, in addition to reducing the biological risk in the management of study specimens generating anatomical models that are easily accessible. Methods: A retrospective analysis of the materials and methods previously used in the research groups of the University of the Forest was carried out to make a subsequent selection of specimens to be used according to their frequency of use, as well as an observation of easily accessible tissue preservation materials without prior evidence, finding as objectives the heart of pig and the brain with respect to raw material and polyester resin as polymer. Results: In this study two specimens (human and pig) were taken from which five cuts were taken from the different planes to perform this plastination technique in which the anatomical composition, muscles and different vessels were identified. Once the plastination technique was explored in these fresh specimens, changes were observed, some slight in the different variables such as dimensions, color, texture and shape, but that meet the expectations of preserving a specimen for teaching purposes. Based on observation and analysis, the behaviour of these variables in the anatomical parts before and after the plastination process is determined. In addition, by the simple correlation method, sample behavior in texture, flexibility, retraction and pig or human anatomical details could be determined. In graph 1, we can observe by comparison the variations in color that were noticed from the first phase of the process. It is observed that in the dehydration phase a lighter shade is achieved but subsequently in the phase of forced impregnation reaches darker shades varying to brown; subsequently a recovery of the color in the drying phase was evident, with whitening of the anatomical parts where clear differences are possible. As for the texture it is observed that in both specimens the samples acquired hardness and rigidity at the time of dehydration with acetone, so it is inferred that losing water and bodily fluids is lost by this process the flexibility is also lost and the organ acquires greater rigidity, which provides greater resistance to manipulation. Based on the retraction of the organs and taking into account that the technique of plastination in one of its stages in the dehydration of the structure is explained because they are retracted. In the preservation of anatomical details it was found that both organs can be clearly and accurately identified the different anatomical accidents of importance Conclusions: Plastination becomes a significant learning building element, either for the student based on anatomy knowledge, while reducing safety concerns over the use of formaldehyde due to the health risks of teachers and students exposed. In order to meet the objective of this research project, the technique of plastination in pig and human brain hearts was standardized, which developed a protocol that includes the chemicals used and the times used at each stage of that procedure. As for the results, differences were found in the variables such as weight, thickness, texture after the realization of said technique preserved in whether the anatomical details and allowing the proper study of the organ.

Fixation is one of the processes in preparing histology and pathology. The common material for fixation is buffered formalin including paraformaldehyde. However, the effect of the damaged cells, which is fixed for a long time, causes the research for other fixation materials to become necessary. In addition, paraformaldehyde is also harmful to human body and natural environment. Ethanol is one of the alternative fixation materials, which has been used for two hundred years. It has been used for many purposes, both in routine staining and immunohistochemistry. Nonetheless, no research confirms its effect on the electron microscope. The authors studied the effect of 50 % of ethanol on the cell membrane, organelles, and nucleus of Purkinje cells (Neuron purkinjense) observed on a light microscope and Transmitted Electron Microscope (TEM). Then it was compared to buffered formalin. In the light microscope, it shows that both of fixations have no different effects of the morphology of the cell membrane, cytoplasm, the nucleus of Purkinje cells and the neutrophils. We assume that our 50 % of ethanol concentration is almost the same as BF 10 % in the ability of hardening tissue and color absorption based on the previous study. In TEM, the structure of the cell membrane, organelles, and cytoplasm of Purkinje cell look broken in the cerebellum of 50 % of ethanol except for the nucleus. There was no significant difference diameter of the nucleus. It happened in general because of the shrinkage effect of ethanol. However, the authors recommend using 50 % of ethanol for routine staining. [ABSTRACT FROM AUTHOR]

Background: The primary aim of this study was to collect information on the surgical procedures used to implant two cochlear implant variants (non-pin and pin: Concerto and Concerto Pin from Med-El) in adults and children and to assess their medium-term stability. A secondary aim was to assess the safety of these variants, both of which permit a minimally invasive surgical protocol to be used. The pin variant has greater flexibility in positioning and fixing of the implant, with the pins ensuring implant stability; also it requires less or no drilling and no tie-down sutures. Materials and Methods: Non-pin and pin cochlear implant variants (Concerto and Concerto Pin from Med-El) were implanted in adults and children (n = 116) in 5 clinics. The different surgical techniques and methods of implant fixation were documented intraoperatively. Implant stability was subjectively assessed at first fitting and again approximately 3 and 6 months later. Safety was assessed based on the number and severity of adverse events. Results: With all non-pin variants suture fixation was always performed, but with the pin variant this was done for just 43% of adults and 49% of children (in the remainder, no additional fixation was performed). The study demonstrated the stability of both cochlear implant variants in children and adults, with no shifting or rocking observed. There were 33 adverse events reported during the study, 10 of which (9%) were classified as related to the device or procedure. Conclusions: Implant stability and safety can be achieved through various surgical techniques and fixation methods when implanting either the Concerto or Concerto Pin. [ABSTRACT FROM AUTHOR]

Since ancient times, techniques for the study of the brain have been developed for didactic or neurosurgical purposes. By 1934, Josef Klingler developed a cerebral hemisphere preparation technique based on formalin fixation and freezing to isolate the cerebral tracts. The aim of this article was to analyze the preparation methods used for tracts dissection in human and animal brains. A review of the literature using Web of Science, Scopus, Pubmed, Medline and Scielo databases, with the following descriptors: Dissection, Brain, Tract, with the boolean operator "AND" among them, also in spanish, until June 2018. Twenty-six documents were selected, and we analized the following variables: specimen, number of cerebral hemispheres, formalin concentration, fixing time, temperature, freezing time and tracts. In the selected literature, a total of 410 cerebral hemispheres were analyzed, 372 from humans and 38 from animals; 330 were preserved in 10 % formalin, 20 in 5 % formalin and the rest in other concentrations. The fixation time was variable between 10 and 180 days, as well as the temperature and freezing time (-10 ºC and -20 ºC, between 8 and 30 days). In all cases it was reported that, in whole or in part, the cerebral fascicles of association were isolated. In the preparation of cerebral hemispheres for dissection of tracts, Klingler recommend that 5 % formalin for the fixation of specimens; however, 80 % of the hemispheres used were fixed in 10 % formalin, and in this concentration, the time of fixation, temperature and time of freezing was variable, achieving, in all the cases analyzed, the partial or total dissection of the tracts.

Objective: To compare the efficacy and safety of prescription pattern in treatment of multifragmentary patellar fractures in a trauma reference center. Material and methods: We conducted a cross-sectional study of patient’s record with multifragmentary patellar fractures from December 2010 to December 2013, comparing treatments that include tension band wire, simple cerclage, double cerclage to bone-tendon junction and conservative treatment. Results: With a total of 92 patients, including 60 women (65.21%) and 32 men (34.78%), with an average age of 61 years. In the double cerclage, surgery time was shorter (average 38 minutes), and the range of motion showed improvement since the first month. Minor complications were observed in patients treated conservatively (arthrofibrosis). Conclusions: At our institution, the most efficient method was the double cerclage to the bone-tendon junction presenting shorter duration of surgery, less ischemic time and faster recovery with range of motion close to normal since the first month after surgery (p = 0.000). The safest method of treatment was conservative treatment, with fewer cases with complications (p = 0.184). [ABSTRACT FROM AUTHOR]

At the University of Buenos Aires in the Faculty of Veterinary Sciences, the method of fixation and conservation of cadavers traditionally used is the 10% formaldehyde solution. Safety in the use of formaldehyde is currently under review. In this work, alternative methods for the fixation and conservation of cadaveric material are presented. Fresh beef was used in pieces of 5 x 3 x 2 cm (M. latissimus dorsi) that were randomly assigned to five treatments by immersion, in solutions of buffered formaldehyde (pH7), of Mc. Cormick and Larssen Modified; with and without previous fixation in 10% formalin for both Mc. Cormick as Larssen. Observations were made for 10 weeks registering color, odor, consistency and size. In week 6, histological sections of the pieces were made by inclusion in paraffin, section in slide microtome and staining with hematoxylin and eosin. The solution of Mc. Cormick remained transparent and the pieces retained their size, a color between grayish pink and dark red, firm consistency slightly higher in the previously unfixed. With the modified Larssen solution, only good preservation characteristics could be obtained in the previously fixed part. The absence of formalin in the mixtures was also evidenced in the histological results. We can conclude that the solution of Mc. Cormick acts as fixer and conservator, while the modified Larssen solution is only conservative in previously fixed parts. A reduction was achieved in the amount of formaldehyde used for preservation, reducing the risk of exposure. Both solutions require a prior elaboration process with respect to the use of formaldehyde at 10% and imply a higher economic cost, disadvantages of little importance compared to the benefits they present.

Las fuerzas superficiales entre partículas coloidales de resina y fibra dominan el comportamiento y las propiedades finales de papel y celulosa. Aquí se describe el uso de Microscopía de Fuerza Atómica (AFM) para medir directamente las fuerzas de interacción entre la superficie de un substrato plano "funcionalizado" con resina de madera y la superficie de una microesfera de vidrio en soluciones de electrolito a pH controlado y a temperatura ambiente. El substrato convertido en hidrofílico es una hoja de poliestireno recubierta con una película ultra fina de resina natural. La carga superficial del substrato "funcionalizado" imita la de las micelas de resina, la microestructura preferida de la resina en agua, y la carga sobre la microesfera imita la de las fibras de madera. Las curvas de fuerza AFM son interpretadas a la luz del balance entre fuerzas atractivas -van der Waals- y repulsivas -electrostáticas- de la teoría continua clásica DLVO de fuerzas para sistemas coloidales. Las medidas muestran una fuerte y persistente repulsión de muy corto rango, a distancias de separación menores a 100 Å que no puede ser explicada por la teoría DLVO. Estas fuerzas repulsivas que actúan como barreras al contacto o a la coagulación tienen su origen en capas de agua altamente ordenadas en la vecindad de las superficies eléctricamente cargadas. El tamaño e intensidad de la barrera dependen de la magnitud y densidad de la carga eléctrica en las superficies que interactúan, que a su vez dependen de sus composiciones químicas y del medio acuoso. La repulsión aumenta con el pH y disminuye con la concentración y tamaño del electrolito. Fuerzas AFM de alejamiento entre substrato y microesfera, después de ocurrido el contacto, revelan una correlación aparentemente no reportada antes entre concentración de electrolito y adhesión. La adhesión aumenta con la concentración y tamaño del electrolito. Fenómenos complejos como dusting, desprendimiento de resina durante el uso del papel, pueden ser controlados mediante regulación del ambiente fluido durante el proceso de fabricación.Surface and adhesive forces between colloidal wood particles of resin and fiber dominate the behavior and final properties of paper and cellulose. This paper describes the use of Atomic Force Microscopy (AFM) to measure the interaction force between a resin "functionalized" substrate and a glass microsphere in aqueous pH-controlled electrolyte solutions at ambient temperature. The water-wet made substrate is a hydrophobic polystyrene film coated with an extremely thin film of wood fatty and resin acids. The surface charge on the "functionalized" substrate mimics that on resin micelles, the preferred microstructure of resin in water, and the charge on the microsphere mimics that on wood fibers. AFM force curves are analyzed to the light of the balance between attractive forces -van derWaals- and repulsive forces -electrostatic- from the classical continuum DLVO theory of colloidal forces. Force measurements show strong and persistent short-range repulsive forces at distances less than 100 Å which are not explained by the DLVO theory. These repulsive forces that act as barriers to contact or coagulation originate on highly ordered water in the neighborhood of the charged surfaces. The barrier size and intensity depend on the magnitude and density of the electrical charges on the interacting surfaces, which in turn depends on their chemical composition, and on the aqueous media. Repulsion increases with pH and decreases with electrolyte concentration. AFM flat-microsphere pull-off forces reveal an apparently unreported correlation between electrolyte concentration and adhesion. Adhesion increases with electrolyte concentration and size. Complex phenomena such as dusting, the release of resin upon paper use due to poor resin-fiber bondage, can thus be controlled by regulating the aqueous media during papermaking.

La Estación Meteorológica de la UNU reportó para ese período los promedios de las condiciones meteorológicas: temperatura 26.55°C, precipitación 26.55 mm, hora sol de 159.63 horas sol/año, humedad relativa del 84%. El objetivo ha sido determinar las cantidades de carbono almacenado y fijado en una plantación de palma aceitera y aguaje. Las plantaciones están instaladas en ecosistemas de altura con suelos degradados y sus edades fueron 29 años para palma aceitera, 20 años para aguaje; el método utilizado fue no destructivo y se tomaron muestras de biomasa aérea (hojas, altura, estípite) y suelo para palma aceitera. Para el caso de aguaje, se han registrado los datos de altura de la planta. En ambos casos se utilizaron fórmulas alométrica para determinar densidad aparente y contenido de carbono almacenado en la biomasa aérea y fijado en el suelo. Los resultados mostraron que el almacenamiento de carbono en la biomasa aérea de la palma aceitera, ha sido en total 31.2610 toneladas/hectárea, distribuidos de la siguiente forma: hojas: 7.8578 ton C/Ha; estípite: 23.4024 ton C/ha. Mientras que la fijación en el suelo ha sido de 3.730 toneladas/hectárea. Para el caso del aguaje, se encontró que en promedio almacena 2,164 toneladas de Carbono/hectárea

BACKGROUND: One of the first signs of aging belongs to the upper third of the face. At the same time, the height and shape of the eyebrows are key points of the periorbital aesthetics. A tired or sad look implies that the complex eyebrow-upper eyelid is showing one or more of this signs. OBJECTIVE: To evaluate long-term results of a technique for endoscopic brow lifting, consisting on minimal incisions, a biplanar dissection and a different fixation technique designed for helping reshape the brow. MATERIAL AND METHOD A retrospective study was made including patients submitted to brow lifting from 2010 to 2016, with six-month follow-up at least. RESULTS: Twenty-five patients were included that fulfilled the criteria for the study and were analyzed for brow position changes in height and shape. All the patients were treated by the senior authors using the technique described. In most patients (96%) long-term results were obtained. There not were cases with excessive elevation of the brow or esthetic bother referred by patients or considered by authors. There was not hematoma, seroma, paresis nor infections. CONCLUSIONS: This particular surgical technique has shown the advantage of being minimally invasive and effective. Careful analysis of the patient should be made to decide both the technique and the changes desired by the patient and the surgeon. The technique described is another option for approaching and fixating the eyebrow. [ABSTRACT FROM AUTHOR]
