Colony development of laser printed eukaryotic (yeast and microalga) microorganisms in co-culture
Authors: Taidi Behnam , Lebernede Guillaume , Koch Lothar , Perre Patrick , Chichkov Boris
Published: June 2017

 Laser Induced Forward Transfer (LIFT) bioprinting is one of a group of techniques that have been largely applied for printing mammalian cells so far. Bioprinting allows precise placement of viable cells in a defined matrix with the aim of directed three-dimensional development of tissues. In this study, laser bioprinting is used to precisely place eukaryotic microorganisms in specific patterns that allow growth and microscopic observation of the organisms’ micro-colonies. Saccharomyces cerevisiae var. bayanus and Chlorella vulgaris are used as model organisms for this purpose. Growth and development of the micro-colonies are studied via confocal microscopy and the colonies’ growth rates are determined by image analysis. The developed protocols for printing of microorganisms and growth-rate determination of the micro-colonies are very promising for future studies of colony growth and development.

Published: June 2017

La energía eólica se muestra como una alternativa técnica y económica con posibilidades de ser implementada en zonas en donde por sus necesidades energéticas y características meteorológicas esta tecnología sea posible. Se relacionan a continuación los parámetros básicos a tener en cuenta en el estudio del comportamiento del viento atmosférico en la capa límite, como un proceso aleatorio estacionario y en condiciones de atmósfera neutra. Con base en lo anterior se establece en este trabajo el procedimiento que se debe seguir durante un proceso de simulación del viento atmosférico mediante la determinación de la función de densidad espectral (PSD) que aproxime la intensidad de turbulencia de las fluctuaciones de la velocidad del viento. Haciendo uso del simulador de aerogenerador del laboratorio de Ing. Mecánica de la Universidad de los Andes se programan los perfiles de velocidad del viento medido y del viento simulado, comparándose en cada caso la potencia generada.
La complejidad del mercado bursátil latinoamericano a partir de un modelo autómata celular conductual
Authors: Talero Sarmiento Leonardo Hernán , Duarte Duarte Juan Benjamín , Garcés Carreño Laura Daniela
Published: June 2017

La presente investigación busca evaluar el nivel de complejidad del mercado latinoamericano, mediante la construcción de un modelo autómata celular. Para ello se estudian seis índices bursátiles: COLCAP, IPSA, MERVAL, MEXBOL, SPBLPGPT e IBOV, en el periodo 2004-2016. Estas series son analizadas a partir de su comportamiento estadístico, el ajuste de retornos y la estimación de su grado de complejidad. Este último es contrastado posteriormente con el nivel de complejidad obtenido mediante la simulación de un mercado bursátil artificial, y se concluye que los mercados latinoamericanos, a pesar de presentar diferencias, suelen tener tendencias similares, ya que su grado de complejidad no puede ser pronosticado por un modelo autómata celular conductual basado netamente en la imitación.

Para tal efecto se realiza un análisis institucional de políticas, normas y directrices en una muestra de diez países: ocho de Latinoamérica, más Estados Unidos e Inglaterra.  El principal resultado indica que el actual régimen institucional tanto legislativo como ético no soluciona la tensión que genera el interés privado y el interés público en el desempeño profesional de un economista en una economía de mercado. Es necesario incorporar una articulación flexible que facilite una interpretación sencilla y concreta que oriente al mejoramiento de la calidad del servicio privado y público que desempeña un economista.
Genetic diversity analysis of endemic species, Garcinia cambogia Gaertn using randomly amplified Polymorphic DNA markers
Authors: P Santosh , Arakera Suresh B.
Published: June 2017

Polymerase chain reaction based random amplified polymorphic DNA (PCR-RAPD) markers were employed to assess genetic diversity in eight Garcinia  cambogia  genotypes. Among the 20 random primers used in the present investigation, 9 primers showed polymorphism. A total number of 227 bands were obtained from 9 primers, out of which 225 were polymorphic, showing 99.11% polymorphism. An average of 25.22 bands per primer was scored and average number of polymorphic bands found to be 25. The eight accessions fall into two major clusters. Cluster analysis showed that the red and yellow accessions cannot be regarded as two different varieties. The use of red and yellow fruits for commercial and medicinal purposes, respectively, is purely based on consumer preference.

La varias veces pionera Capilla Bakócz = The several times pioneer chapel Bakócz
Authors: Corrales Pérez Laura
Published: June 2017

Levantada a principios del siglo XVI en Esztergom, la capilla  funeraria del cardenal Tamás Bakócz se aleja del gótico  dominante para constituir el ejemplo más precoz y depurado de arquitectura renacentista al norte de los Alpes. Prematuramente próxima a sus contemporáneos italianos, se vio influenciada por la procedencia artística de sus maestros constructores, y por la poderosa figura de su mecenas y su estrecha relación con el papa Julio II, embarcado en la concepción de la nueva basílica  vaticana. Relevante es también su historia tras la muerte de su patrón. Tras sobrevivir ilesa a casi 150 años de dominación  otomana, fue objeto a comienzos del siglo XIX de una  impresionante y pionera operación de despiece y traslado que aún hoy sigue sorprendiendo por su contemporánea concepción sobre el valor de lo monumental. Abstract Built in the first decade of the 16th century in the Hungarian city of Esztergom, the burial chapel of Cardinal Tamás Bakócz  abandoned the dominant Gothic style to constitute the earliest and most perfect example of Renaissance architecture north of the Alps. Surprisingly close to Italian examples from the same period, this Hungarian building was strongly conditioned by the artistic background of its building masters. However, its main influence came from the leading figure of the Cardinal and his close relationship with the Pope Julius II, who was working at that time in the project for the new Vatican basilica. It is also highly relevant the evolution of the chapel after Bakócz's death. It survived to 150 years of Turkish occupation before being cut into pieces and transferred to a new place. This pioneer process took place in the early beginning of XIX century and is still surprising for the modern concept about restoration that it involves.
Tres artículos de Max Bill
Authors: Escaño Rodríguez Maite
Published: June 2017

Se presentan aquí las traducciones de tres artículos de Max Bill de gran relevancia sobre su pensamiento acerca del diseño en los años previos a la creación de la escuela de Ulm. Los dos primeros, escritos en 1946 y 1949, tratan de experiencias propias de diseño del autor y de las ideas de belleza y función en el diseño respectivamente. El segundo corresponde a una conferencia dada en el Werkbund suizo en 1948 de cuyo debate surgió la exposición itinerante “Die gute Form” (La buena Forma). El tercero, aunque escrito en 1979, es un comentario crítico sobre la lámpara de techo de la Bauhaus, antecedente de las creadas por él y descritas el primero de sus artículos.
Padley Mill: a question of interpretation
Authors: Blundell Jones Peter
Published: June 2017

The transformation into a house of an old mill from the mid- eighteen century in Padley Gorg, within the now known as Peak District National Park in the vicinity of Sheffield, UK, has raised a significant number of the problems of conservation and restauration of ancient industrial heritage, focused and concentrated in a single building. To restore and maintain the property as a museum or to make a significant change of use were some of the dilemmas faced by the author. After the final decision, the architectural work revealed as laborious, unexpected in its pre-existing conditions and opposed to any attempt of developing a personal style. The result is a hybrid building which shows its historical layers and, although modified, clearly better preserved than without any intervention at all.

Dicha lectura clarifica la existencia de estrategias de diseño compartidas y contribuye a entenderlos como una parte significativa del legado de la Arquitectura Moderna.
Transistor Clamped H-Bridge Five-Level Multilevel Inverter for Photovoltaic Application – A Hardware Prototype Implementation Using Inverted Double Reference Single Carrier PWM Technique
Authors: Bhaskar Mahajan Sagar , Padmanaban Sanjeevikumar , Blaabjerg Frede , Mohammed Anzari
Published: June 2017

Inverters are Power Electronic System (PES) and proficient to converting Direct Currents (DC) into Alternating Currents (AC). Conventional two-level inverter has drawbacks like high Total Harmonic Distortions (THD), high voltage across power switch, high dv/dt of output voltage and electromagnetic interferences. Multilevel Inverters (MLIs) are employed to overcome the drawbacks of conventional two-level inverter. Multilevel Inverters generate an AC voltage using small voltage steps obtained with the help of DC supplies or capacitor banks. This paper deals with the implementation of a Transistor Clamped H-Bridge Multilevel Inverter (TCHB-MLI) using Inverted Double Reference Single Carrier Pulse Width Modulation (IDRSCPWM) technique for photovoltaic application. The proposed TCHB-MLI requires less number of power switches and drivers to achieve maximum number of output level. The analysis of the multilevel inverter output is done in terms of its harmonic spectrum, output voltage and output current for modulation indices 0.85, 1 and 1.25. The control signals for the power switches of the proposed TCHB-MLI are developed by using SPARTAN 3E-XCS250E trainer kit. Experimental results will verify the functionality, design of the proposed TCHB-MLI and IDRSCPWM Technique.
Leadership, Communication, and Negotiation Across a Diverse Workforce*
Authors: Clohisy Denis R. , Yaszemski Michael J. , Lipman Joanne
Published: June 2017

The current workforce in the United States is rapidly changing and is increasingly inclusive of individuals from a broad range of ages, ethnicities, and cultural backgrounds. Engaging and leading a diverse workforce creates great opportunities for innovation and adaptation in our evolving medical economic and clinical care delivery environment. For optimal engagement of employees and partners, orthopaedic surgeons must develop the necessary skills for executing change inside complex organizations and across teams composed of a variety of providers and skilled workers. Important skills include leadership, effective communication, and negotiation within an ever-changing employee milieu. Understanding generalizable differences between age-based generations can increase the effectiveness of one’s strategies to execute change and increase organizational performance. One of the greatest impediments to effective communication and negotiations that all leaders face is unconscious bias. For leaders, even the tiniest unconscious biases have an outsized impact. Common domains that harbor unconscious bias include sex, race, and ethnicity. Addressing unconscious bias begins with developing awareness and then deploying various tactics that might include equity in compensation, promotion, and “being heard.” Effective negotiation skills also are essential to lead a diverse workforce and develop a successful organization. The most basic goal in any negotiation should be to establish a relationship (or deepen an existing relationship) while seeking an agreement that provides win-win opportunities for all parties. To effectively achieve a win-win scenario, leaders must recognize and address their tendency to interpret others’ behaviors, values, and beliefs through the lens of their own beliefs and experiences. Finally, and fortunately, there is a set of leader attributes that transcends the generational differences and diversity that is encountered in the workplace. These attributes include integrity, credibility, effective listening, having a vision of your destination, fairness, humility, and caring.

Published: June 2017

Update

This article was updated on July 12, 2017, because of a previous error. On page 1043, in the Results section of the Abstract, the sentence that had read “A significantly higher percentage of patients had complications or subsequent surgical procedures in the early than in the late group (38% [6 of 16] versus 93% [14 of 15], p < 0.001)” now reads “A significantly lower percentage of patients had complications or subsequent surgical procedures in the early than in the late group (38% [6 of 16] versus 93% [14 of 15], p < 0.001).”

An erratum has been published: J Bone Joint Surg Am. 2017 Aug 16;99(16):e91.

Background:

The aim of this study was to investigate the outcomes in a large series of Essex-Lopresti injuries (ELIs) and to compare patients with early and late diagnoses.

Methods:

Thirty-one patients with an ELI (average age and standard deviation [SD], 46 ± 10 years) who were followed for a minimum of 2 years were included in the study. Patients were grouped according to whether the ELI had been diagnosed early (on the day of the injury) or late (>4 weeks after the radial head injury). Acute treatment of early-diagnosed ELI included temporary stabilization of the distal radioulnar joint (DRUJ) by Kirschner wires with the forearm in supination for 6 weeks. Clinical outcomes were assessed on the basis of the range of motion, Mayo Elbow Performance Score (MEPS), Mayo Wrist Score (MWS), visual analog scale (VAS) score for wrist and elbow pain, and Disabilities of the Arm, Shoulder and Hand (DASH) score.

Results:

The ELI was diagnosed on the day of the injury in 16 patients (52%; the early group) and late (at a mean of 7 ± 7 months; range, 1 to 24 months) in 15 (48%; the late group). After a mean duration of follow-up of 5.3 ± 3.0 years (range, 2.0 to 13.1 years), patients with an early diagnosed ELI had significantly better clinical outcomes, compared with those with a late diagnosis, with regard to the MEPS (91.3 ± 8.7 versus 74.7 ± 15.3, p = 0.003), MWS (81.3 ± 16.5 versus 66.3 ± 17.6, p = 0.019), DASH score (12.5 ± 8.7 versus 45.3 ± 23.5, p = 0.001), VAS elbow pain score (0.7 ± 1.1 versus 3.3 ± 2.1, p = 0.001), and VAS wrist pain score (0.9 ± 1.2 versus 3.9 ± 1.7, p < 0.001). The ranges of motion of the elbow and wrist did not differ significantly between the early and late groups (p > 0.05). A significantly lower percentage of patients had complications or subsequent surgical procedures in the early than in the late group (38% [6 of 16] versus 93% [14 of 15], p < 0.001).

Conclusions:

Early diagnosis of an ELI with temporary stabilization of the DRUJ leads to satisfactory clinical mid-term results, whereas late diagnosis of an ELI is associated with a deteriorated outcome.

Ethnooceanography and the intersection of shar'i aspects to determination of the early of Ramadan and Shawwal by Joguru Sultanate of Tidore. The determination of the early of the new month of Ramadan and Shawwal was very important for Muslims because it is related to the time of worship. Judge syara 'The Sultanate of Tidore (Joguru) has long applied the method of determining the early month of Hijri (Ramadan and Shawwal) through tidal movement observed on "akebai" included in ethooceanography and called Joguru Method (MJ). Hilal that has never been seen in Tidore and its surrounding areas in the long-term cycle of moon (34 years) caused its early moon to be inapplicable due to non-fulfillment of the requirement of hisab (hadith). MJ makes observation (rukyat) change of tidal movement on "akebai" is "ijtihād". The appropriateness of the scientific aspects of ethnoocaenography and the intersection of the shar'i aspects make it a comparative method of determining the beginning of the new month of Hijri in astronomy (hilāl). Required the expansion of the meaning of the “hilāl” as an indicator of the beginning of the month of the Hijri calendar.

Hilal yang tidak pernah terlihat di wilayah Tidore dan sekitarnya selama siklus jangka panjang (34 tahun) menyebabkan hisab awal bulan tidak dapat diaplikasikan akibat tidak terpenuhinya persyaratan hisab (hadis). MJ melakukan peng­amatan (rukyat) perubahan tinggi air pada “akebai” adalah “ijtihad”. Terdapat ke­sesuaian aspek sains dari ethnoocaenography serta titik temu aspek syar’i yang menjadikan MJ berpotensi sebagai metode utama sekaligus sebagai metode pem­banding dari metode umum dalam penentuan awal bulan baru Hijriah. Diperlukan perluasan makna kata “hilal” sebagai indikator awal bulan baru penanggalan Hijriah.
Políticas institucionales para favorecer el acceso y la permanencia en universidades argentinas: un análisis de cuatro instituciones del conurbano bonaerense

Published: June 2017

El objetivo de este artículo es analizar las políticas que instrumentan cuatro universidades argentinas, situadas en el conurbano bonaerense, para favorecer el acceso y la permanencia durante el proceso de ingreso y en el primer año de los estudios de grado. Se parte del supuesto de que los factores institucionales —que incluyen la manera en que se organizan los procesos de enseñanza y aprendizaje, el currículo y las estrategias de apoyo a los alumnos— pueden jugar un rol fundamental en la retención estudiantil. El análisis se realiza con base en fuentes secundarias, así como documentos recopilados y entrevistas realizadas a autoridades y coordinadores de los cursos de ingreso de las cuatro instituciones. Los logros y las limitaciones de las políticas —frente al enorme desafío de mejorar en términos de calidad, pertinencia e inclusión— plantean la necesidad de combinar las actuales medidas de apoyo material y pedagógico con un foco más claro en la enseñanza y el currículo, a través de mayores recursos y de un trabajo más estrecho con los docentes en el re-diseño de las estrategias institucionales.
Operational and financial performance of fossil fuel power plants within a high renewable energy mix
Authors: Eser Patrick , Chokani Ndaona , Abhari Reza S.
Published: June 2017

The operation of conventional power plants in the 2030 high-renewable energy system of central Europe with high penetration of renewables is simulated in this work. Novel insights are gained in this work, since the generation, transmission and demand models have high geographic resolution, down to scale of individual units, with hourly temporal resolution. It is shown that the increases in the partload efficiency that optimize gas power plants’ financial performance in 2030 are highly dependent on the variability in power production of renewable power plants that are in close proximity to the gas power plants. While coal power plants are also cycled more, an increased baseload efficiency is more beneficial for their financial viability. Thus, there is a need for OEMs to offer a wide range of technology solutions to cover all customers’ needs in electricity markets with high penetrations of renewables. Therefore there is an increased investment risk for OEMs as they strive to match their customers’ future needs.
LEGAL SCHOLACTIVISTS IN THE THIRD WORLD: BETWEEN AMBITION, ALTRUISM AND ACCESS
Authors: Farid Cynthia
Published: June 2017

This article argues that legal agents from the Third World play an important role in facilitating and advancing subaltern claims by operating as “scholactivists”. The mediums they use for such advances necessarily require leveraging of the international legal discourse and various international forums. However, their success is constrained by the dynamics of the international legal field and the ability to assimilate within a global cosmopolitan class. Legal scholactivists are examined here from a place-based perspective, locating their praxis in the geographical Third World. In so doing, this article traces the life and work of Dr. Kamal Hossain, a celebrated Bangladeshi lawyer with many accolades at home and abroad. In his long and illustrious career, Hossain has voiced subaltern and Third World concerns on the global stage through a variety of mediums including domestic and international legal practice, advocacy, international organizations and various non-profit, non-governmental and civil society organizational efforts. Although the references to Bangladesh may be very specific and are used as an illustration, it is hoped that the claims made in this paper will be generalizable and applicable to similarly situated countries.

Desarrollo de un vehículo solar híbrido “XUE revolution”
Authors: Salazar Marin Edgar Alonso , Arroyave Londoño Juan Felipe , Guevara Rojas Brayan
Published: June 2017

El ahorro energético que requiere el país es el resultado de muchos eventos. Una mala administración del recurso hídrico para las hidroeléctricas y la falta de una matriz energética más diversificada para el país son algunas de las causas de un futuro racionamiento. Las energías renovables son una alternativa totalmente viable para nuestro país, tanto para satisfacer la demanda eléctrica como para convertirse en una opción interesante para un transporte verdaderamente sostenible y limpio. El transporte sigue siendo uno de las fuentes con mayor aporte de gases efecto invernadero, causa principal del calentamiento global que se ha venido manifestando progresivamente con climas más cálidos e impredecibles. El proyecto consiste en el desarrollo de un vehículo unipersonal cuyas fuentes energéticas son compartidas entre la energía solar a través de panel fotovoltaico y propulsión humana a través de sistema de transmisión de potencia desde pedales hasta la rueda de tracción. Los complementos energéticos permiten satisfacer demandas en diversas solicitaciones de carga (desde superficies planas hasta pendientes del 12%). El sistema fotovoltaico lo conforman un panel de 345 Wp, una batería de 20 Ah y 48 Vdc (960 Wh), un motor eléctrico de 2 kW. El vehículo alcanza una autonomía (eléctrica) de 2 horas (solo motor a 40 km/h en superficie plana). No obstante en presencia del sol y/o con apoyo del piloto, el vehículo podrá movilizarse sin problema alguno. En la parte mecánica se resalta el trabajo realizado para los sistemas de dirección y tracción.

El ser humano es un individuo producto de la naturaleza, y en su andar evolutivo ha tenido que sortear innumerables obstáculos a través de ayudas que le ha brindado su evolución. Muchas de estas ayudas evolutivas, han sido físicas y motrices, pero también habilidades mentales, las cuales a través de ambientes de estimulación se han desarrollado para sostener al hombre a lo largo de la historia. Durante muchos años, diversos psicólogos e investigadores interesados en conocer el funcionamiento cognitivo del cerebro y de estas habilidades, han desarrollado experimentos que les han ayudado a ir revelando poco a poco esta actividad mental. Varios de estos experimentos se han enfocado en entender las capacidades innatas con las que los niños nacen que les permite interactuar con los demás seres humanos y con el entorno.

Reactor de membrana multitubular para la producción de hidrógeno: guía de diseño
Authors: Maya Vinueza Luis Eduardo
Published: June 2017

El presente trabajo analiza el rendimiento de un reactor de membrana multitubular para la producción de hidrógeno con la reacción water-gas shift. Las condiciones de operación se definen considerando que el sistema se encuentra acoplado con un reformado de etanol y celdas de combustible para la producción de energía. Usando un modelo que considera solo dirección axial y estado estable, se presentan varias herramientas de diseño con el fin de lograr conversiones altas mediante la variación de la presión en el lado de la reacción y el número de tubos. Finalmente, el análisis de diferentes configuraciones de reactores, ayudó a concluir que la conversión de monóxido de carbono cambia proporcionalmente con aumentos de presión en la coraza y el número de tubos, que se explica por el incremento en la permeación de hidrógeno.

Meditation benefits have been widely supported by many research works. It is considered a natural way of reducing stress, depression, and other anxiety disorders. However, meditation process is a breathe pursuing task that requires long time training to avoid the so-called mind wandering. In this work, we propose a neural-feedback system that detects when mind wanders and generates an audible signal, this way patient’s attention is recovered back again. Finally, we support our approach by testing the system on novice and advanced meditators.
Criticality assessment risk; contribution of fuzzy logic
Authors: Masmoudi S. , Dhiaf M.M.
Published: June 2017

In order to determine the criticality of a risk, an assessment of the probability of occurrence (notion of frequency) and of the impact (notion of severity) are to be estimated. The criticality is the product of the probability of its occurrence and the impact that the risk has on the project, hence on the whole company. So, the practice of matrix or the criticality grid considering these two dimensions is necessary. However, the criticality grid involves the insufficiencies inherent to the subjective behavior of expert judgments and to the imprecise information engaged in the assessment of the risk. Taking into account the problems of the imperfection implied in the Conventional Criticality Matrix (CCM), the objective of this work is to develop a Fuzzy Criticality Matrix (FCM) to overcome these difficulties. The proposed model aims at improving the system of fuzzy inference. The proposed approach is applied to a test system which is the company SAROST S.A.

The article deals with general principles of the techniques: the need to complete the work within the planned time interval (sprint); holding daily scrum-meetings; making efficient decisions on issues arising etc. The authors underline the importance of building industrious team taking into account the temper, spirits and individual preferences of each member. The role of the leader is clearly indicated in the process of team building. There are listed conditions for effective staff motivation.
DEVELOPMENT OF BASIC METHODOLOGY FOR EVALUATING FINANCIAL SITUATION OF ORGANIZATIONS
Authors: Antonov Anton Vladimirovich
Published: June 2017

The financial situation of an organization can be defined as a multidimensional economic category that characterizes, by means of a set of indicators, the placement, ownership and use of financial resources, as well as their sufficiency at each point in time. In connection with this, it can be stated that an assessment of the financial condition of an economic entity allows to conclude that there is an effective management of resources and financial indicators in the period under study. This article reveals the shortcomings associated with the assessment of the financial condition of the organization by calculating relative indicators (financial ratios). The article proposes a model for assessing the financial condition of the organization, based on the standard ordering of the growth rates of the four groups of financial ratios. At the first stage of the study, a reference matrix of the rates of indicators change is built; at the second stage - the matrix of the actual rates of indicators change. At the final stage of the study, an integral indicator is formed, calculated on the basis of a comparison of the reference and actual matrices, allowing to assess the financial condition of the organization for a certain period of time.

Indicators of product sophistication and factor intensities: Measurement matters
Authors: Huber Stephan
Published: June 2017

The widely used PRODY indicator by Hausmann et al. [ 1 ] [What you Export Matters; Journal of Economic Growth: 12, 1–25] allows the calculation of product sophistication and factor intensities at high levels of disaggregation. In this paper I deal with its measurement, its conceptional limitations, its sensitivity to subjective decision making, its alternatives, and how to reap the best possible benefit from its usage. I introduce a theory-based alternative and investigate the sensitivity of empirical results with respect to different measurements. In particular, I re-estimate the main results of Hausmann et al. [ 1 ] with 75 variants of measurement. Small changes to the sample, the aggregation level, or the construction of the indicator can make a difference. Moreover, I offer two STATA programs that ease the calculation of various PRODY variants.
