Performance Comparison of AFDS PMSG During Voltage Regulation by Mechanical Field-weakening in Extended-speed-range
Authors: Gupta Shailendra Kumar , Srivastava Rakesh Kumar
Published: October 2019

Background:

Axial-flux permanent magnet synchronous generators (AFDS PMSG) have
been found suitable in wind energy conversion system and electric vehicle owing to its compactness,
high torque capability at low speed, high torque to inertia ratio, modular geometry, and high
magnet usability index. Such applications require the generator to operate in Extended Speed Range
(ESR). In ESR, voltage regulation is achieved by generator field-weakening. Usually, negative daxis
current is injected in the armature winding of the generator to achieve field-weakening. However,
in the axial-flux machine field-weakening by current injection is not substantial due to the low
inductance of the machine and use of permanent magnets with high coercivity. We have revised all
patents related to field-weakening methods applied to axial-flux permanent magnet generators.

Methods:

Therefore, this paper emphasizes field-weakening using mechanical methods. This paper
compares the performance of AFDS PMSG topologies based on its mechanical-field-weakeningbased
voltage regulation capability. In this paper, generator field-weakening is achieved by angularly
displacing, one of the stators with respect to the other via a mechanical actuator.

Results:

The experimental results show that during voltage regulation of the DS PMSG with perfectsinusoidal
back-emf characteristic, least amount of harmonics is injected in the generated output
power.

Conclusion:

Thus, the same is best suited to design an automotive generator based on MFW method
for wind energy conversion system and electric vehicle running in ESR.

Although traditional methods of data collection in naturalistic settings can shed light on constructs of interest to researchers, advances in sensor-based technology allow researchers to capture continuous physiological and behavioral data to provide a more comprehensive understanding of the constructs that are examined in a dynamic health care setting. This study gives examples for implementing technology-facilitated approaches and provides the following recommendations for conducting such longitudinal, sensor-based research, with both environmental and wearable sensors in a health care setting: pilot test sensors and software early and often; build trust with key stakeholders and with potential participants who may be wary of sensor-based data collection and concerned about privacy; generate excitement for novel, new technology during recruitment; monitor incoming sensor data to troubleshoot sensor issues; and consider the logistical constraints of sensor-based research. The study describes how these recommendations were successfully implemented by providing examples from a large-scale, longitudinal, sensor-based study of hospital employees at a large hospital in California. The knowledge gained from this study may be helpful to researchers interested in obtaining dynamic, longitudinal sensor data from both wearable and environmental sensors in a health care setting (eg, a hospital) to obtain a more comprehensive understanding of constructs of interest in an ecologically valid, secure, and efficient way.

Published: October 2019

Hoy en día, las plantas existentes de energía a base de carbón presentes en el mundo emiten cerca de 2 billones de toneladas de CO2 al año. Debido a su ingeniería fundamental y las ventajas económicas que compiten en tecnologías de separación, las operaciones de membrana están siendo exploradas para la separación de CO2 y otros gases de combustión de las emisiones de centrales eléctricas basados en combustibles fósiles. [1] Los enrejados imidazolato tipo zeolita (ZIFs) son nuevos materiales microporosos con diversidad de estructuras y tamaños de poros, así como grandes áreas superficiales. Las membranas de estos materiales poseen un gran potencial para la separación de mezclas de gases de interés energético y ambiental. [2-4] En este trabajo se presenta la síntesis y caracterización de dos membranas potencialmente útiles para separación de CO2, a partir del compuesto conocido como ZIF-8 y una modificación del mismo usando una mezcla de metales (Zn y Co). Con esta modificación se espera modular la entalpía de interacción y con ello a su vez, la selectividad de la membrana como resultado de la participación de dos tipos de metales en el enrejado molecular.

Actividad antimicótica de nanopartículas
Authors: Castrillón Rivera Laura E. , Palma Ramos Alejandro
Published: October 2019

RESUMEN: La terapia antifúngica tiene como principal desventaja que existen pocas moléculas que carecen de acción citotóxica hacia las células de mamífero, ya que comparten muchas características funcionales porque también son células eucarióticas. Por otra parte, debido a la naturaleza química de muchas de estas moléculas que son poco solubles en agua, este hecho puede afectar su biodisponibilidad. Lo anterior limita su acción terapéutica y exige el diseño de formas farmacéuticas efectivas. Por esta razón, el desarrollo de nuevas tecnologías y síntesis de nanomateriales surge como una posible alternativa para el tratamiento de las infecciones por hongos. En este trabajo de revisión se presentan los desarrollos nanotecnológicos con miras a la obtención de formas farmacéuticas eficientes y seguras de los antimicóticos como son los liposomas, nanopartículas de plata, nanopartículas lipídicas sólidas, nanopartículas poliméricas y microtúbulos lipídicos.

El derecho al acceso a la seguridad social de los trabajadores al servicio del Estado
Authors: García Arizaga Karen Yarely , Pérez Padrón Diana
Published: October 2019

Los trabajadores al servicio del Estado representan un sector laboral desprotegido por diversas legislaciones burocráticas locales en materia de seguridad social; por mencionar un caso específico, los trabajadores temporales, pues son excluidos de la aplicación de la ley o no disfrutan de manera integral de ese derecho. El presente artículo tiene como principal objetivo demostrar el tratamiento discriminatorio que sufren los trabajadores burócratas en razón de la categoría asignada por la temporalidad de su nombramiento respecto de los trabajadores permanentes, pues en materia de seguridad social reciben una protección diferente, no obstante que ambos prestan un servicio personal y subordinado al Estado. Se plantea como hipótesis que, para el reconocimiento del derecho humano a la seguridad social de los trabajadores burócratas, su categoría no debe ser un factor determinante, y que la legislación federal y local debe ser acorde al principio de igualdad, para garantizar el reconocimiento y acceso a este derecho. Para ello, utilizo el método comparativo para el análisis de las legislaciones locales tanto en materia burocrática como de seguridad social; asimismo, con el estudio del caso se describió la situación de vulnerabilidad de algunos sectores de estos trabajadores.

Published: October 2019

A diferencia de los jóvenes universitarios de hace 25 años, en la actualidad éstos se enfrentan a dispositivos, contenidos y tecnologías que los desafían a estar en constante actualización. Este escenario les otorga posibilidades, en cuanto a medios y modos, para construir significados. En la universidad, los estudiantes realizan trabajos académicos que requieren tanto de una competencia multimodal como de una multimedial. Este artículo describe las representaciones sociales de la escritura multimodal y multimedial que manifiestan estudiantes chilenos del área de la salud en el nuevo contexto tecnológico. Se aplicó una encuesta a una muestra de 255 estudiantes del área de la salud. Los hallazgos indican que las representaciones sociales sobre la escritura multimodal y multimedial son restringidas, es decir, consideran la escritura esencialmente anclada al modo verbal y tienen escasa conciencia acerca del valor de elementos multimodales y multimediales en sus textos escritos.

Strategies for boards of directors to meet the challenges associated with AI, gentrification, and emerging technological advances
Authors: Grove Hugh , Clouse Mac , Xu Tracy
Published: October 2019

The major research question or issue in this paper is to develop strategies for companies and Boards of Directors to seize opportunities from emerging technological advances, instead of being threatened by artificial intelligence (AI), gentrification, and other new technologies. For example, in 2019 Microsoft made a $500 million positive response to Seattle’s gentrification while Amazon made a negative gentrification response by withdrawing its New York City headquarters offer. Seven steps for digital transformation were advocated herein, using the strategy of “Adapt or Die”. Another strategy was to create person/machine partnerships, and six steps were recommended for job retraining in this environment where today will be the slowest day for technology change in this lifetime. An additional strategy was to benchmark the 50 Smartest Companies in the world in order to try to adopt their best business practices. The emergence of AI and robotics replacing jobs can be viewed as a positive trend if companies and Boards of Directors take advantage of these technological breakthroughs to help businesses, employees, and communities become more efficient and effective, especially with a broader stakeholder and sustainability perspective, as opposed to the narrow shareholder perspective. The major sections of this paper are gentrification, positive and negative responses to gentrification, the evolving technology environment for jobs, “adapt or die” strategy with implications for companies and Boards of Directors, related stakeholder and sustainability focus, strategies to avoid “Fear of Missing Out”, and summary.

Authors: Ahmed Heshu Jalal , Ganjo Aryan R.
Published: October 2019

Background: Carbapenems are usually the choice of antimicrobial agents in infections produced by Enterobacteriaceae bacteria-producing ESBL (extended spectrum β-lactamases). Carbapenemase production among clinical isolates of Enterobacteriaceae has been widely reported and Resistance to carbapenems group is generally due to production of Carbapenemases. Phenotypic determination and distinction of Carbapenemases in drug-resistant gram-negative is crucial for appropriate infection control. Materials and Methods: Carbapenemase production among Enterobacteriaceae isolates was identified phenotypically using a commercially available EDTA-combined disc diffusion test containing inhibitors to the various carbapenemase classes and Modified Hodge test (MHT). Results: A total of 98 Enterobacteriaceae isolates were included, 42(42.8%) were Multi-drug resistant (MDR), 27(27.5%) were XDR while 8(8.2%) exhibited pan-drug resistance (PDR). Of the 74 isolates of Escherichia coli and 24 Klebsiella pneumoniae that were positive for carbapenemase production, 12 (16.2%) and 9 (37.5%) were Metallo beta-lactamase (MBL) producers respectively, Hence, the overall prevalence of carbapenemase-producing Escherichia coli and Klebsiella pneumoniae in this study were 47.3% and 87.5%. Conclusion: Carbapenemase-producing Enterobacteriaceae was indeed recognized in our hospitals. The EDTA-combination disk test was a rapid, cost-effective and suitable method which will be able to identify and distinguish the carbapenem-resistant bacterial isolates within the hospitals especially when molecular detection techniques are not available.

Entrepreneurial competencies are connected to venture performance, but the link between these competencies and the business model (BM) innovation is scarcely studied. This article is among the first to study entrepreneurial competencies as a driving force for BM innovation. This paper presents a qualitative empirical study of six innovative horticulture entrepreneurs in Finland. We contribute to two separate literature streams, competence and BM literature, by combining competence categories (Mitchelmore and Rowley 2010) and BM Innovation model (Foss and Saebi 2017) in the analysis of innovative entrepreneurs. This paper provides evidence on entrepreneurial competencies being internal drivers for BM innovation, and also identifies the core entrepreneurial competences related to BM innovation.
Em torno de uma epistemologia preta

Jean-Marc Lévy-Leblond, físico e professor da Universidade de Nice, França, em seu livro “O pensar e a prática da ciência: antinomias da razão”, ao se utilizar de uma analogia nada arbitrária, atestou a perspectiva etnocentrada europeia: “Se for preciso encontrar um deus para a epistemologia, que seja um Jano policéfalo” (LÉVY-LEBLOND, 2004, p. 397).Ora, ao escolher Jano, deus das portas e das estradas, senhor dos caminhos, deus romano, Lévy-Leblond está forçosamente de um lado de uma fronteira epistêmica, fazendo valer certa verdade. A analogia utilizada constitui o supostamente natural como fonte de verdade, uma verdade perspectiva e estratégica que confirma um imaginário violento e lhe dá respaldo. Trata-se da violência epistêmica do Norte.O físico francês não acionou apenas um lado. Exerceu seu poder de dizer “algo” e colocou em curso uma velha cantilena duvidosa de que os outros poderão um dia tornar-se feliz, desde que, sob a batuta de uma cultura europeia ilusoriamente superior. Deu voz a um desejo de domínio cognitivo que se expressa por meio de afirmações, aparentemente, neutras ou casuais, as quais devem ser colocadas em seu devido lugar por meio de uma problematização séria.

Resolution of reactive arthritis after splenectomy in a dog with a nonneoplastic splenic hyperplastic nodule
Authors: Yuki Masashi , Kainuma Daiki , Naitoh Eiji , Aoyama Reina , Hirano Takashi
Published: October 2019

CASE DESCRIPTION

A 10-year-old spayed female Golden Retriever was examined because of a 3-month history of lethargy, anorexia, and stumbling gait.

CLINICAL FINDINGS

A splenic mass was identified on abdominal radiography and ultrasonography, and results of clinicopathologic findings indicated nonregenerative anemia, leukocytosis, and high serum C-reactive protein (CRP) concentration. To further investigate the cause of the dog's high serum CRP concentration, radiography and arthrocentesis were performed bilaterally on the carpal and stifle joints. On the basis of results, anemia of chronic disease associated with polyarthritis caused by the localized splenic mass was suspected.

TREATMENT AND OUTCOME

After splenectomy, there were improvements in the dog's clinical signs, polyarthritis, nonregenerative anemia, and serum CRP concentration. The splenic mass was histologically diagnosed as a nonneoplastic splenic hyperplastic nodule with evidence of omental adhesion.

CLINICAL RELEVANCE

Findings indicated that nonneoplastic splenic hyperplastic nodules could result in reactive polyarthritis, although such nodules have not to our knowledge been described previously as an underlying cause of polyarthritis. Therefore, veterinarians should investigate for nonneoplastic splenic hyperplastic nodules in addition to other typical underlying causes when treating dogs with polyarthritis.
