INTERACTION OF THE LAWS OF ELECTRODYNAMICS IN THE HUBER EFFECT
Authors: Silvestrov Anton , Zimenkov Dmytro
Published: May 2017

A complex physical phenomenon, first discovered by engineer J. Huber in 1951, is investigated. From the perspective of an external observer, the phenomenon is as follows: an electric current is passed through the wheel pairs of the car moving from the rail to the rail. The current, passing through the movable contacts of the wheels and rails, creates an additional (up to the moment of inertia) torque. The research task is to explain the reason for the occurrence of torque. Based on the analysis of individual components of the electrodynamic phenomenon discovered by Huber, an algorithm for the successive interaction of the individual components of the effect is found on the basis of the laws of classical electrodynamics: electric, ferromagnetic, and mechanical.

The identity of the effect is explained, both for the wheel pair and for the bearing (Kosyrev-Milroy engine). For the first time, the cause of the appearance of the torque is revealed: relative movement of surface charges in the region of the movable electrical contact to the wheel body and the rails (or balls and guides). Moving charges unevenly magnetized ferromagnetic bodies according to the Biot-Savart-Laplace law. Due to the reduction in the clearance of the oncoming side of the wheel (or balls) and the increase on the trailing side, the pulling force from the oncoming side and, accordingly, the moment are more than on trailing side. The presented theoretical explanations completely correspond to the experimental investigation of the effect carried out by different scientists at different times.

Authors: Cherepii Nataliya , Rasputina Lesia
Published: May 2017

According to the data of the world statistics there is observed the continuous growth of chronic obstructive pulmonary disease (COPD). According to the last data of the World health organization (WHO), for today there is near 250 mln persons with chronic obstructive pulmonary disease (COPD), and this disease becomes as cause of death of near 3 mln persons annually.

Aim: to establish the prevalence of undiagnosed chronic pulmonary disease (COPD) among persons, who consider themselves as healthy ones and regularly undergo medical check-ups; to estimate the frequency of chronic obstructive pulmonary disease (COPD) according to the data of medical documentation.

Methods and materials: 525 persons, older than 35, who did not have in an anamnesis any chronic diseases of respiratory tract, were interrogated. At the following stage, persons, who had taken 18 points or more underwent a spirography with bronchodilatation test, using 400 mcg of salbutamol and were interrogated by the modified questionnaire of short breath by the medical research council (MRC) and test of the chronic obstructive pulmonary disease estimation (COPD) (TEC). There were examined 136 patients, mean age (51,5±0,8), men were 81(59,5 %) mean age (52,2±1,1) and women – 55(40,4 %) mean age (50,7±0,9).

There were analyzed 56 medical stories of patients, treated at therapeutic departments of the city clinic because of internal organs diseases with the concomitant diagnosis of chronic obstructive pulmonary disease (COPD).

Among persons with first revealed chronic obstructive pulmonary disease у 21 (26,6 %) was reveled І severity degree according to GOLD, in 26 persons (32,9 %) – GOLD ІІ, in 28 (35,4 %) – GOLD ІІІ, in 4 (5,1 %) – GOLD ІV severity degree, so 32 patients did not receive basic treatment at all.

At the same time among patients with COPD diagnosis in medical documentation only in 38,4 % this diagnosis was spirographically verified, the hyperdiagnostics of disease on the base of complaints and age characteristic took place in other cases.

Authors: Severgin Vladisav , Prohoda Sergei , Prohoda Aleksey
Published: May 2017

Despite certain achievements in lung cancer treatment, the essential number of patients is subjected to palliative and symptomatic treatment. Hemoptysis addition is the one of most heavy symptoms of unresectable lung cancer. No less heavy complication is an atelectasis and hypoventilation of a lobe or a whole lung, which clinical image is attended by respiratory failure phenomena or association of purulent-septic pneumonia. The combination of endoscopic hemostasis with roentgen endovascular embolization of bronchial arteries (REEBA) allows to increase patients’ live quality and to prolong it for some time.

In the clinic REEBA has been done in 121 patients with unresectable forms of lung cancer. The causes of surgical treatment refusal were a widespread tumor process, age, and severity of associated pathology.

Hemostasis was achieved in 112 patients. A relapse of pulmonary bleeding was observed in 11 patients, who underwent the repeated REEBA. Lethal outcome was observed in 5 cases. Hemostasis was ineffective in 9 patients.

Thus, the experience of using REEBA and endoscopic hemostasis at complicated forms of unresectable lung cancer allows to increase the life quality and in further to realize chemoradial therapy that gives a possibility to prolong a patient’s life.

Creation of marshmallow with natural dyes is impossible without investigation of properties of products and estimation of its quality. Our objects of investigation were organoleptic, physico-chemical and antioxidant properties of the products at storage for 30 days. The six of marshmallow samples were the objects of our research. They differed in the type of structuring agent - gelatin or gelatin with solubilized substances and the type of dye – water or water-alcohol extract of cryopowder from Sudanese rose or water-alcohol extract of cryopowder from вlack chokeberry.

Necessary indexes of quality are supplied for the new types of marshmallow with natural dyes. Moisture content (19.0 ... 21.5 %), total acidity (3.5 °Brix), density (0.51 ... 0.67 g/cm3), reducing substances content (not more than 13.6 %) were determined by standard methods. Use of natural anthocyanin dyes let us to increase antioxidant properties of the ready product. Value of antioxidant capacity of the new samples, determined with use of galvanostatic coulometry method, is in 2 ... 2.5 times more than the same results for samples, made without the dyes.

It was established that short time storage (up to 2 days) of marshmallow with natural anthocyanin dyes at temperature (15...18)°С and relative air humidity 60...75 % is possible without packing materials. Storage of the products in hermetically polyethylene wrap and cardboard box provides high indexes of quality, stability of colour in long time (up to 30 days). It was shown that antioxidant properties of marshmallow with water-alcohol extracts of cryopowder from Sudanese rose and black chokeberry remain stable.

The new developed types of marshmallow with natural anthocyanin dyes makes wide market of confectionery and can be used for correction of feeding of a man.

Published: May 2017

The studies are devoted to the scientific grounding of expedience of after-harvest processing by antioxidant compositions for preventing the development of pathogenic microflora on fruit surfaces during a long storage. For the studies were used apple fruits of the varieties Aidared, Golden Dushesse, Renet Simirenka, pear fruits of the varieties Victoria, Crimea Raisin and Cure, plum fruits of the varieties Voloshka, Stanley and Italian Ugorka. Fruits were processed by immersion in the following antioxidant compositions: ACM is a mixture of dimethyl sulfoxide, ionol and polyethylene glycols; AARL – mixture of ascorbic acid, routin and lecithin; DL – mixture of dimethyl sulfoxide, ionol and lecithin. Fruits, processed by water, were used as a control. Exposition - 10 seconds. Storage was carried out at the temperature 0±1 ºС, relative air humidity 90–95 %. It was established that in the period of fruits laying for storage, the mean amount of epiphyte microflora was fixed on surfaces of plump and pear fruits of the mean ripening term. In the variety composition of epiphyte microflora prevailed spores of mesophyl aerobic and facultative-anaerobic microorganisms. Their mean number on apple fruits surface was 9,6·103 CCU/g, pear fruits – 10,6 103 CCU/g, plump fruits – 18·103CCCU/g. AOC processing of all types of fruits essentially decreased the speed of both MAFAnM and micromycetes growth. It was demonstrated that the used compositions in 2…3,5 times decreased the level of day losses from microbiological spoilage during the whole storage period. The most positive effect was received at using compositions, based on dystinol and lecithin. Multifactor analysis determined that the level of day losses from microbiological spoilage was mainly influenced by factors of raw material variety features (factor A) and antioxidant compositions processing (factor D). The shares of influence are 24 and 21 % respectively.
Removal of ammonium from aqueous solution by three modified molecular sieves: a comparative study
Authors: An Ying
Published: May 2017

Molecular sieves (Ms) modified either by treatment with a NaCl solution, or by microwave treatment, or by both NaCl and microwave treatment were employed to promote the removal of ammonium from aqueous solution. Parameters such as NaCl concentration, NaCl stirring time, microwave power and microwave irradiation time were optimized with respect to ammonium removal. The specific surface area, structural characteristics and porous properties of both raw and modified Ms were studied using N2 adsorption–desorption, scanning electron microscopy, X-ray fluorescence, and energy dispersive spectroscopy. The results demonstrate that NaCl-microwave modified Ms had the highest capacity to remove ammonium (4.32 mg g−1), followed by NaCl modified Ms (3.41 mg g−1), microwave modified Ms (3.40 mg g−1), and raw Ms (2.37 mg g−1). Optimization of the modification conditions using a response surface methodology resulted in a 1.94 mol L−1 NaCl solution, a microwave power of 400 W and an irradiation time of 5.1 min. NaCl-microwave modification effectively increased the removal capacity of ammonium by increasing the sodium content, modifying the surface morphology, and enlarging both the surface area and the pore volume for the Ms.
A prototype of novel agro-waste based column bed device for removal of textile dye Optilan Red
Authors: Gita Samchetshabam , Shukla S. P. , Choudhury T. G. , Prakash C. , Singh A. R.
Published: May 2017

The aim of the study was to assess the potentiality of an agro-waste (sugarcane bagasse) for removal of the textile dye (Optilan Red) using novel column based filtration unit with a packed column of chemically treated sugarcane bagasse. The treated and untreated sugarcane bagasse (biosorbent) were characterized by Fourier transform infrared (FT-IR) spectroscopy. Effect of initial dye concentration on percentage removal of dye, equilibrium adsorption of sugarcane bagasse, kinetic studies, breakthrough point equilibrium and desorption of dye from the column material were studied. An inverse dependence of initial dye concentration on percent removal of dye was observed, whereas the equilibrium adsorption (qe) showed a direct relationship with dye concentration. The time required for reaching breakthrough point was 120 min. Desorption of dye through alkali wash resulted in complete desorption after 1 h washing of the column for its reuse for next cycle. FT-IR analysis shows vibration in valence bands of the hydrogen bond of OH group, and the bands of intra-molecular and intermolecular hydrogen bonds, which results in interaction of treated bagasse with Optilan Red textile dye. The present study showed that more than 93% removal of the dye can be achieved in the concentration range 10–50 ppm (aqueous solution). The removal efficiency of the column remained almost unchanged for the treatment of dye-house wastewater spiked with the dye. The agro-waste based treatment process shows a considerable potential for a low-cost treatment of dye contaminated water.

Authors: El-Borai Mohamed A. , Awad Mohamed K. , Rizk H.F. , Atlam Faten M.
Published: May 2017

Aim and Objective: Pyrazolo pyridine skeleton is an interesting class of heterocycles due to its diverse
biological properties including antitumor, antioxidant and antibacterial activities. The objective of this
work was established in vitro antiproliferative activities against MCF-7 (breast cancer) human cell lines for of
the synthesized compounds IIIa-e. The effect of the molecular and electronic structures on the biological activity
was performed to compare the theoretical data with the experimental observations.

Materials and Method:

The synthesized compounds were prepared by conventional heating and microwave irradiation
technique. The structure of the prepared compounds was confirmed by different spectroscopic tools.
The compounds IIIa-e was tested for antitumor activity against breast cancer cell line. The quantum chemical,
molecular docking and SAR studies were performed for the prepared compounds.

Results:

The microwave irradiation as a source of energy was used to improve the yield and to reduce the time
of the reaction. Under this technique, the reaction time was reduced from 4-8 hours to 15-25 min. The yield of
the reactions was increased from 81% to 92%. Also, the obtained products were cleaner.

Conclusion:

The quantum chemical descriptors confirmed that inhibitor1-(4-methoxyphenyl)-3-(1-methyl-1Himidazol-
4-yl)-6-phenyl-1H-pyrazolo[3,4-b]- pyridine-4-ol (IIIb) is the most potent and reactive among the
investigated compounds. This conclusion is congruent with the results obtained experimentally.
First Total Synthesis of Pamamycin-621D
Authors: Norouzi-Arasi Hassan , Salom-Roig Xavier J. , Lanners Steve , Hanquet Gilles
Published: May 2017

Aim and Objective: The objective of our work was to synthesize and fully characterize Pamamycin-
621D, one of the less abundant members of a large family of macrodiolides with antimycobacterial properties,
which had never been synthesized before. Furthermore, we also wished to improve our general strategy by using
a new unsaturated precursor.

Materials and Method:

A new unsaturated ethylketone precursor was prepared using alkene cross metathesis,
and a convergent and flexible strategy based on a key diastereoselective aldol addition was implemented to afford
pamamycin-621D in 12 steps from that precursor.

Results:

Pamamycin-621D has been obtained and fully characterized for the first time. The structure of
pamamycin-621D was confirmed by HRMS and comparison of 1H-NMR spectra with the natural pamamycin-
621D. Both optical rotation and 13C-NMR had not been published previously due to lack of material, and the
latter are reported here for the first time. Given the scarce characterization available previously, our synthesis
also gives additional support to the initial structural assignment of pamamycin-621D. A significant improvement
of the key aldol addition via the use of a new unsaturated precursor is also reported.

Conclusion:

The work described above constitutes the first total synthesis of pamamycin-621D and has enabled
us to fully characterize this scarcely available natural product. More importantly, this work highlights the
fact that our synthetic approach provides ready access to various members of the pamamycin family, allowing
possible studies on structure-activity relationships and mode of action of even the least abundant of these natural
products. The synthesis of other pamamycin congeners and biological investigations will be published in
due course.
Does Total Wrist Arthroplasty for Treatment of Posttraumatic Wrist Joint Osteoarthritis in Young Patients Always Lead to Restriction of High-demand Activities of Daily Living? Case Report and Brief Review of Recent Literature
Authors: Schmidt Ingo
Published: May 2017

Background:

Posttraumatic ulnar carpal translocation is a very rare condition that is caused either by fracture-dislocation injury or by purely ligamentous injury of the wrist. Its prognosis is poor and development of posttraumatic pancarpal wrist joint osteoarthritis is inevitable, and options for treatment are total wrist fusion or total wrist arthroplasty.

Methods:

A 24-year-old male sustained a fracture-related injury in his left wrist that was accompanied with a second ligamentous distorsion-related injury 1 year later in the same wrist. Seven years after first injury, a posttraumatic pancarpal wrist joint osteoarthritis has developed that was caused by posttraumatic ulnar carpal translocation. The patient was treated by total wrist arthroplasty with use of the MaestroTM Wrist Reconstructive System.

Results:

With our patient, it is unclear whether posttraumatic ulnar carpal translocation occurred either as result of the first fracture-related injury or as result of the second ligamentous distorsion-related injury or as result of both injuries. The 31-year-old patient could be reemployed completely in his original occupation as a mechanic for big agriculture machines and load his wrist with more than 10 pounds. In order to preserve motion, the patient reported that he would undergo the same total wrist arthroplasty a second time were it necessary.

Conclusion:

We report on a young male receiving total wrist arthroplasty and resulting in good restoration of his high-demand claims in activities of daily living, respectively. However, it cannot be concluded that total wrist arthroplasty is to be preferred generally over total wrist fusion in young patients. Essential prerequisite for this motion-preserving procedure is the compliance of patients.

Villanueva-Sert

Published: May 2017

Siendo Carlos Villanueva y José Luis Sert dos personajes contemporáneos, sus obras no suelen relacionarse, ambos tenían la voluntad de conjugar las artes en una sola expresión, encontrar la emoción plástica del espacio.

Los itinerarios propuestos, recorren parte de la geografía moderna que ambos transitaron: París, Caracas, Puerto Ordaz, Ciudad Bolívar, y Saint Paul-de-Vence. Tres obras de cada arquitecto, de programas similares, de tres tipologías y momentos distintos, darán cuenta de la evolución de sus respectivas teorías, y con ello la evolución del concepto en distintos estadios de la modernidad. Sin abandonar los grandes caminos abiertos por Le Corbusier, buscaron adaptarse a unas topografías locales desde la impronta meridional y tropical de su cultura latina. En la aproximación a sus obras, sumaremos las reflexiones del artista Léger para definir un marco teórico dentro del amplio espectro histórico –en palabras del suizo- por “alcanzar una perfección absoluta en la ocupación del espacio.”

Cubierta velaria en el Claustro de Sor Juana
Authors: González Victor Hugo Roldán
Published: May 2017

El uso de la tecnología de las velarias se ha venido incrementado en años recientes debido a que ofrecen muchas ventajas frente a otros sistemas constructivos, lo que a su vez ha impulsado el desarrollo de mejores materiales y nuevas soluciones formales, sin embargo es un campo del que poco se conoce. El presente artículo describe las ideas detrás de la concepción y realización de la cubierta velaria para un edificio catalogado, de carácter histórico como lo es el ex convento de San Jerónimo en el centro de la Ciudad de México.

Asimismo, se hace un recorrido por la historia del inmueble, desde su origen, destrucción y posterior recuperación, hasta las razones que dieron sustento a la propuesta de la velaria, que dio como resultado un patio con más vitalidad.

Paisajes en el borde: dos apuntes sobre entropía en Mexicali
Authors: Peimbert Duarte Alejandro
Published: May 2017

Dos espacios públicos emplazados en bordes de distinta naturaleza: por un lado, una plaza que conmemora el centenario de la fundación de la ciudad de Mexicali, ubicada en un intersticio, permanece vacía, encausada hacia la ruina; por otro, a unos pasos de la frontera, uno de los primeros parques de la ciudad representa lo lleno, donde cohabita la diversidad de esta tierra de migrantes, atendida inadecuadamente por la administración local. Esta producción de espacio público estimula la idea de que el desarrollo se encuentra detenido en un proceso de gestación que, paradójicamente, evidencia un constante crecimiento.
La (ir)responsable óptica de la ciudad dependiente
Authors: Lozoya Johanna
Published: May 2017

Durante la segunda mitad del siglo veinte, la teoría económica de la dependencia proveyó a una generación de pensadores latinoamericanos de un amplio repertorio de argumentos culturalistas a través de los cuales se explicó durante décadas todo cuanto ocurría en la región. A partir de dicha mirada ideológica, o en gran medida debido a ésta, el pensamiento urbano arquitectónico en América Latina construyó una argumentación histórica e historiográfica fundamentada en el concepto “dependencia cultural”. El presente artículo reflexiona sobre las consecuencias ideológicas e historiográficas de este imaginario a partir de algunos aspectos del pensamiento de Marina Waisman.

La casa de Mies: exhibicionismo y coleccionismo
Authors: Colomina Beatriz
Published: May 2017

La arquitectura de Mies está dominada por la idea de la casa, al grado que sus edificios públicos pueden entenderse como extensiones de una continua investigación sobre ella. De hecho, Mies desarrolló un concepto de casa tan radical que desplazó los supuestos que regían todos los tipos de edificios. Mirar las casas de Mies es mirar un cambio radical en arquitectura.
Este poderoso desplazamiento de las tradiciones, cuyos efectos todavía pueden sentirse hoy en una serie de réplicas sísmicas continuadas, fue lanzado con los más delicados materiales e insinuaciones. Mies utilizó las publicaciones y las exposiciones efímeras para emprender una nueva manera de pensar que parece que a él mismo le sorprendió y le llevó décadas desarrollar en su totalidad.
El Mies que conocemos, la célebre figura del Movimiento moderno, fue incubado en el espacio inmaterial de las exposiciones temporales y de las publicaciones y, en última instancia, absorbió la lógica de la exposición en la sustancia misma de la arquitectura.

Museo moderno frente a Museo contemporáneo La crisis de las tipologías ante un cambio de paradigma
Authors: Baldellou Plaza Ángela
Published: May 2017

En este artículo expongo una reflexión sobre cómo la pérdida de valores ha derivado en la disolución de la tipología de Museo generando un “Museo contemporáneo” que, frente al Museo moderno, es un museo global que no pertenece a ningún lugar concreto, un museo del desarraigo, desligado incluso
de su función. Su origen conceptual basado en una idea “social” participativa y regeneradora ha degenerado, mayoritariamente, hacia una simplificación superficial que se resume en museos-logotipo como respuesta de supervivencia arquitectónica adaptada a un nuevo paradigma social.
La casa de un hombre es su castillo: fortificaciones domésticas
Authors: Ekirch A. Roger
Published: May 2017

Mucho antes de que los pueblos fortificaran sus puertas, en las comunidades de la temprana modernidad, la naturaleza señalaba la retirada del día; para muchas familias europeas, el ambiente rural –no los relojes– llevaba el ritmo de la vida diaria. Sólo las campanas de las parroquias, que sonaban a intervalos durante el día, rivalizaban con la precisión de la naturaleza. Innumerables augurios anunciaban el final del día, muchos de ellos descifrables inconscientemente y otros intuidos por la sabiduría recibida de generaciones antiguas: hacia el atardecer, los pétalos de las maravillas comenzaban a cerrarse, parvadas de cuervos regresaban a sus nidos y los conejos se excitaban cada vez más; las pupilas de las cabras y las ovejas. 
Sobre luz natural en la arquitectura

Este ensayo se enfoca en los aspectos paisajísticos y ambientales del “poblado dirigido” que Francisco J. Sáenz de Oiza proyectó en el barrio madrileño de Entrevías tomando como referencia "La metrópolis como ciudad jardín" de Hilberseimer. A través del análisis de algunos planos arquitectónicos, de instalaciones y jardinería desarrollados entre 1956 y 1958, y examinando las relaciones que el conjunto establece con la orografía, hidrología, clima y
naturaleza del lugar, es posible considerar Entrevías como una “topografía sensible” que se vincula con la escala urbana y territorial.

De la casa a los espacios íntimos a partir de la descripción fenomenológica de Gaston Bachelard
Authors: Gutiérrez Hernández Fernando
Published: May 2017

Este artículo comenta algunos aspectos de los estudios fenomenológicos de la vivienda a partir de La poética del espacio (1958) de Gaston Bachelard. Para ello, se explora el argumento teórico del topoanálisis en lugares íntimos y cómo ha permeado en el estudio teórico de la arquitectura. Posteriormente, se discute la importancia de la descripción de la casa a través de las ensoñaciones y las memorias, para analizar las implicaciones, críticas y consecuencias de los estudios fenomenológicos en la vivienda contemporánea. El artículo concluye en que el entendimiento del espacio doméstico más allá de sus cualidades espaciales puede propiciar un acercamiento transdisciplinario a través de la arquitectura.
Los grandes desarrollos habitacionales en la ciudad de México:¿proyectos habitacionales o proyectos políticos y económicos?
Authors: Alonso Arenas José Armando , Juárez Pérez Angélica Noemí
Published: May 2017

El modo de habitar doméstico contemporáneo y los grandes desarrollos de vivienda de los siglos xx y xxi en la ciudad de México han visto antepuestas racionalidades políticas y económicas a su objetivo habitacional. Los desarrollos del Milagro mexicano fueron propaganda política del proyecto modernizador del Estado; los del siglo xxi han privilegiado el lucro de promotores inmobiliarios. El resultado, sobre todo en las experiencias recientes, contradice el propósito de favorecer la equidad al producir vivienda.
Prisión, género y sexualidad
Authors: Domínguez Echeverría María Patricia
Published: May 2017

Un grupo de internas de la prisión de Tepepan nos dio la clave para entender el funcionamiento del orden carcelario, en el marco del género y la sexualidad; donde la vida, al interior de la prisión, revela un imperativo de conducta, de condescendencia con la norma. Separar el sexo del género para dejar que éste prolifere, nos permitió entender los desplazamientos de la identidad, donde también se quiebran los destinos de las anatomías para enunciar una sexualidad disidente, abyecta y marginal.

Léna Bergner fue una diseñadora textil formada en la Bauhaus; trabajó en Moscú y fue directora técnica de diseño de la fábrica Dekorativtkan. En 1939 viajó a México, donde trabajó durante 10 años con su pareja, el arquitecto Hannes Meyer, y colaboró con el Taller de Gráfica Popular (tgp) y el Comité Administrador del Programa Federal de Construcción de Escuelas (capfce). Esta investigación pretende dar a conocer el trabajo material e intelectual de la diseñadora, para valorar una labor que no ha sido estudiada por la historia de la arquitectura y el diseño.
Expresiones pictóricas urbanas: paisaje urbano y configuración espacial en Iztacalco
Authors: Violante Soria Eduardo
Published: May 2017

Este artículo se enfoca en las prácticas pictóricas localizadas en el paisaje urbano de Iztacalco. A través de sistemas de información geográficas se pretende encontrar patrones de localización o relaciones de proximidad entre los edificios educativos, el espacio público o la red de transporte público, y la presencia de prácticas pictóricas en los muros de las edificaciones, sin perder de vista la aceptación, familiaridad y tolerancia de los habitantes hacia este tipo de prácticas.
Daniel Buren: la arquitectura de la gráfica en el espacio
Authors: Barrera Rubio H. María Fernanda
Published: May 2017

A partir de una revisión de la carrera de Daniel Buren –artista francés nacido en 1938, en Boulogne- Billancourt, Francia, y considerado uno de los artistas más importantes de nuestro tiempo–, en un lapso de aproximadamente 35 años se puede seguir su interés por la exploración de las relaciones entre
gráfica y arquitectura, en diversas etapas y de diversas formas.
La primera etapa de su producción artística se consolidó a finales de los sesenta, década que estuvo regida por la crítica hacia la institucionalización del arte y la búsqueda de la desaparición del autor en la obra artística; su obra se desarrolló inicialmente junto y en relación con los elementos arquitectónicos que se encuentran en la ciudad para transformarse hacia principios de los ochenta en elementos
arquitectónicos que conforman y delimitan un espacio.
La arquitectura en su dimensión temporal
Authors: Calanchini González Cos Juan Carlos
Published: May 2017

El tiempo somos nosotros, por lo tanto resulta indispensable hablar de él y comenzar por aquéllos que han pensado en el tiempo a lo largo de la historia desde distintos enfoques. Se reflexionará después sobre los cambios y las posibilidades que puede traer consigo, para concluir con un acercamiento a la arquitectura en su estrecha relación con el tiempo y su “muerte,” la cual se propone contemplar como un ciclo de inicios perpetuos.
Lo no permanente en la consolidación urbano-arquitectónica
Authors: Erazo Solarte Nelson Ivan
Published: May 2017

Este artículo plantea el tiempo como una dimensión en la que se estructuran y conectan diferentes variables que inciden en la consolidación de los sectores urbanos populares. La condición evolutiva de estos sectores se explora con el concepto de lo “no-permanente” el cual, al atravesar las diferentes dinámicas socio-culturales, permite pensar en cómo la incertidumbre, lo simbólico, lo diverso y lo múltiple pueden definir en el tiempo las características físicas de los territorios.

El caso de estudio será el barrio Berlín de Cali, Colombia, a partir del proceso social y cultural de invasión y urbanización pirata donde se tomará como referente la variable de lo político,  para exponer lo urbano-arquitectónico como algo fluctuante y no permanente. 
La ciudad y los portadores del tiempo

Published: May 2017

La ciudad moderna del siglo xxi no se adapta a las necesidades físicas de la
población mayor, la cual afronta enormes inconvenientes para realizar sus
actividades cotidianas. Si nos pusiéramos por un momento en sus zapatos entenderíamos las grandes hazañas que deben sortear para realizar tareas tan sencillas para nosotros como la de subir un escalón. En la actualidad, 9.3%1 de la población mexicana tiene más de 60 años, además se estima que el número de personas mayores se triplicará para el año 2050. A través del tiempo la perspectiva que se tiene de las personas de la tercera edad ha cambiado como parte de un desarrollo histórico donde intervienen procesos culturales, ideológicos, políticos y económicos.

Introduction. An extracranial carotid artery aneurysm is a rare clinical entity with potentially debilitating consequences. Our aim is to present a case of a large internal carotid artery aneurysm combined with medial internal carotid artery (ICA) kinking successfully treated by resection with an end-to-end anastomosis. Case outline. A 34-year-old female patient was admitted to our hospital due to dizziness and frequent non-specific headaches. On admission, routine echocardiography showed an aneurysm of the atrial septum. Multislice computed tomography of the supraaortic branches showed medial kinking of the right ICA with a 15 mm aneurysm localized on the vertex of the angulation. Kinking was present on the left ICA as well, with a small aneurysm of 5 mm in diameter. The right ICA aneurysm was resected and the artery was reconstructed with an end-to-end anastomosis. The postoperative course was uneventful and the patient was symptom-free after a one-year follow-up. Conclusion. We showed that surgery of an aneurysm and kinking of the carotid artery in the medial segment of the ICA is possible and safe to perform. Detailed preoperative preparation, precise surgical technique, and short clamping time all contributed to a good final outcome.

Introduction. Myoepithelioma primarily affects the parotid gland and usually presents as a slow-growing painless lump. The aim of this paper is to report a case of myoepithelioma in the mouth floor. Case outline. A young man noticed a painless increased volume in the left side of the mouth floor region, which after one year of evolution presented as a sessile tumor with normal colored mucosa and the absence of secretion output. Computed tomography with contrast showed an image with slightly heterogeneous density, with well-defined limits. Incisional biopsy was performed under local anesthesia, and pathology examination of the sample revealed a myoepithelial neoplasm. Total excision of the lesion was performed under general anesthesia, and histopathological examination confirmed the diagnosis of the salivary gland myoepithelioma. The patient did not present signs of relapse after a year of follow up. Conclusion. Despite the fact that myoepithelioma originating in the salivary gland are considered rare, especially in the mouth floor, this tumor should be considered in the differential diagnosis of similar lesions. Proper treatment appears to be complete surgical excision and post-operative follow-ups shows should be carried out as long as possible, despite the fact that relapses are extremely rare.

Introduction/Objective. The objective was to assess the effectiveness of laparoscopic gastrectomy, analyzing short-term outcomes of laparoscopic radical gastrectomy in treatment of advanced gastric neoplasms. Methods. We performed a prospective cohort observational study, which included 30 patients who underwent elective radical laparoscopic gastrectomy (total or subtotal) for stomach neoplasms, performed in the period between March 2013 and February 2017. Results. Thirteen patients (43%) had been diagnosed with distal gastric tumors, seven (23%) with proximal gastric tumors, four (13%) with pangastric tumors, four (13%) with mediogastric tumors, and two (7%) with bicentric tumors. Mean operation duration was 286 minutes. The average blood loss was 183 mL. Conversion rate was 10% (three patients). Total of seven (23%) patients had postoperative complications, and mean intensive care unit stay was 1 day. Mean hospital stay after surgery was 13.08 days. The average number of harvested lymph nodes was 33.9, and R0 resection was performed in 87% patients. The overall 30-day mortality rate was 0%. Conclusion. Although technically challenging, laparoscopic gastrectomy is a safe and oncologically adequate procedure in the radical surgical treatment of advanced gastric neoplasms.

Dynamical analysis of lump solution for the (2+1)-dimensional Ito equation
Authors: Tan Wei , Dai Zheng-De , Dai Hou-Ping
Published: May 2017

Exact kinky breather-wave solution, periodic breather-wave solution, and some lump solutions to the (2+1)-dimensional Ito equation are obtained by using an extended homoclinic test technique and Hirota bi-linear method with a perturbation parameter u0. Furthermore, a new non-linear phenomenon in the lump solution, is investigated and discussed. These interesting non-linear phenomena might provide us with useful information on the dynamics of higher-dimensional non-linear wave field.
