    2016-01-01

    Full Text Available En la medición del apego se utilizan las entrevistas que asignan a un individuo un estilo determinado de apego a partir de una descripción cualitativa; las viñetas de autorreporte, en las que una persona puede indicar su estilo de apego y, por último, los instrumentos de medición con opción de respuesta tipo Likert, los cuales permiten análisis y perfiles diferenciados. Empero, en el modelo de ansiedad e intimidad es necesario tomar cuartiles basados en medianas, que ubican a las personas en una tipología particular. El presente estudio describe el proceso de validación de una escala que mide el apego en adultos, que hace posible obtener medidas independientes de los estilos seguro, preocupado, temeroso y evitante. La escala final muestra la existencia de cuatro factores independientes que explican 59.99 % de la varianza. Los ítems muestran cargas factoriales superiores a .50, comunalidades mayores a .40 y un coeficiente alfa total de .72.

  3. Apego y bienestar en mujeres en proceso de tratamiento del cáncer de mama

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Este estudio explora la contribución del vínculo de apego al bienestar de las pacientes en tratamiento por cáncer de mama. Su objetivo es aportar conocimientos sobre como favorecer el afrontamiento del cáncer y de las dificultades que suelen concurrir con el. Un total de 58 mujeres que iban a comenzar un tratamiento de radioterapia por cáncer de mama informaron a través de cuestionarios sobre: síntomas y disfunciones relacionados con la enfermedad y el tratamiento, afectos positivos y negativos, bienestar emocional, contrariedades diarias y vínculo de apego. El análisis de regresión revela que el componente Temor al rechazo y al abandono del apego, la presencia de contrariedades -principalmente las económicas- y la presencia de síntomas físicos predicen el grado de bienestar. Los otros dos componentes del apego (Deseo de cercanía y Preferencia por la independencia no presentan ninguna relación significativa. Contrariamente a lo esperado, la merma de capacidad funcional no predice una disminución del bienestar. Se discute sobre el peso diferencial de las variables medicas y psicosociales en la calidad de vida relacionada con la salud y se concluye la importancia de las intervenciones encaminadas a mejorar el estado emocional durante los tratamientos del cáncer a través de la mejora de las relaciones cercanas.

    Full Text Available Después del parto, las señales sensoriales que emiten las crías contribuyen al establecimiento de la conducta maternal (CM y la formación del apego materno (AM, entendido éste último como "la capacidad conductual y emocional de formar un vínculo selectivo, único y duradero de la cría hacia la madre y viceversa" [1]. El objetivo del presente trabajo fue sistematizar y caracterizar el AM en dos cepas de ratas (Rattus novergicus: Wistar (W y Sprague Dawley (SD. Se registró la frecuencia en las conductas de transporte, búsqueda, olfateo, limpieza de las madres antes, durante y después de la gestación (n= 5/cepa, encontrando diferencias significativas entre cepas sólo en la fase de gestación (Z = 2.19, P<0.05. El AM fue clasificado como alto y bajo con base a la frecuencia de conductas de madre hacia las crías y viceversa (promedio ± 1 DE. No se encontraron diferencias significativas entre el sexo y tipo de AM; sin embargo, la cepa SD mostró una tendencia de preferencia hacia los machos para el apego alto y hacia las hembras para el apego bajo. Al analizar el vínculo madre-cría, en la cepa W se encontró una correlación positiva entre CM y conducta de búsqueda de las crías hacia la madre (r = 0.91, mientras que en la SD la correlación es baja (r = -0.42. Estos datos muestran que en la cepa W el vínculo madre-crías se puede identificar con mayor claridad y que el protocolo diseñado para la evaluación del AM es sensible a las variaciones naturales de la CM por camada y por cepa.

    2005-05-01

    Full Text Available En los últimos años se ha incrementado el interés en el apego de adultos, tanto desde una perspectiva teórica como empírica. Parte de este interés ha sido la evaluación del constructo del apego en estas etapas del desarrollo. Esto ha generado dos tradiciones o líneas de investigación, basadas en los modelos representacional y comportamental del apego, con sistemas de clasificación categoriales y/o dimensionales y con instrumentos distintos. A través de una exhaustiva revisión del surgimiento y desarrollo de estas tradiciones se describen sus características principales, sus ventajas y desventajas, así como sus ámbitos de aplicabilidad. Se concluye sobre la falta de unicidad del constructo del apego y se discute sobre los límites de su medición y aplicación.In recent years the interest in the subject of adult attachment has increased, in the theoretical as well as in the empirical perspective. Much of this interest has been the assessment of the construct of attachment in this phase of development. This endeavor has generated two traditions or lines of research: one is the tradition of the models of state of mind and the other is the behavioral approach of attachment. Both of these approaches have developed their own systems of classification in categories or dimensions and their own research assessment tools. Through an exhaustive revision of the rise and development of these traditions, the scope of this paper is to describe the main characteristics of these approaches, its advantages and disadvantages, as well as its field of action and application. The authors conclude about the lack of integration of the construct of attachment and the limitations of its measurement and application.

    Full Text Available En este trabajo se persiguen dos grandes objetivos: a conocer la asociación entre la vinculación afectiva con los padres en la infancia y la calidad percibida de las relaciones de pareja en la juventud; b analizar el posible efecto mediador, en esa asociación, de la experiencia de apego adulto experimentado en la relación de pareja. En el estudio participaron de manera voluntaria 133 parejas heterosexuales (17-25 años. A través de un cuestionario on line, se evaluaron, en los dos miembros de la relación, la calidad de las relaciones con el padre y la madre en la infancia, el apego con la pareja actual (Ansiedad-Evitación, y la calidad percibida de la propia relación. Los resultados mostraron asociaciones significativamente positivas entre la vinculación afectiva en la infancia y la calidad de la relación, comprobándose además el efecto mediador del apego actual. Por último, se encontraron asociaciones negativas entre la ansiedad y evitación de cada miembro de la pareja y su propia experiencia relacional, y en algún caso, con la experiencia relacional del otro. Estos resultados se discuten en términos de la teoría del apego y su importancia de cara a la calidad de la relación de pareja.

    1994-01-01

    Full Text Available El creciente empleo de la mujer fuera del hogar ha llevado a una gran preocupación respecto a sus efectos sobre la salud emocional de los niños. Preocupacion que tiene su origen en nuestras creencias acerca de la infancia como un período determinante en nuestra vida futura y al papel de la madre como el factor más importante. La presente investigación tuvo como objetivo evaluar estos efectos. Se entrevistó a un grupo de 211 madres representado por 103 enfermeras (empleadas de tiempo completo los últimos cinco años y a 108 amas de casa (no empleadas los últimos cinco años, denominadas madres trabajadoras, MT y madres no trabajadoras, MNT. Se evaluó a uno de sus hijos(as de edad entre 5 y 6 años 11 meses, por medio del dibujo de la familia el cual se calificó en términos de patrones de apego de Bowlby y Ainshworth. Se evaluó, como control, el nivel de desarrollo a partir del dibujo de la figura humana según el procedimiento de Koppitz. No se encontraron diferencias significativas en los patrones de apego entre ambos grupos, aunque sí un porcentaje ligeramente mayor de apego inseguro desorganizado entre los pequeños de MNT. En el nivel de desarrollo cognoscitivo los pequeños de MT mostraron un desarrollo superior a los de MNT. Aunque no de manera significativa, pudo apreciarse una influencia importante de la edad en el tipo de apego: disminución en apego desorganizado y aumento en seguro, y en el nivel de desarrollo: mejor nivel de desarrollo de los cinco a los seis años; así como del sexo: mayor apego desorganizado y menor nivel de desarrollo en varones. En ambos grupos, el porcentaje de niños con apego seguro fue muy inferior al reportado en la literatura internacional; paralelamente encontramos un .porcentaje elevado de niños con apego inseguro (evitativo y desorganizado. Encontramos, por otra parte, que las tensiones de la madre con su pareja tuvieron una influencia negativa en el patrón de apego y en el nivel de

Objetivo: Determinar el nivel de conocimiento teórico y apego al procedimiento dialítico del paciente o familiar. Metodología: Se realizó un estudio descriptivo. Se efectuó una visita domiciliaria, en donde se aplicaron: una lista de cotejo para evaluar el apego al procedimiento, un cuestionario para evaluar los conocimientos teóricos y una cédula de variables clínicas y sociodemográficas. Participaron 24 sujetos, se dividieron en grupo pacientes (GP, donde los pacientes se auto-realizan el procedimiento y familiar (GF, donde los familiares realizan la técnica. Resultados: El nivel de conocimiento teórico en general fue moderado (73.24%, el GP obtuvo un índice más elevado (75.35% que el GF (71.45%. En la técnica, en general, se adhirieron al 80.3% de los pasos, el GF obtuvo mayor índice correcto (81.92% que el GP (78.63%. Conclusión: Los pacientes y familiares demuestran un déficit en ambas áreas, por esto, es necesario evaluarlos periódicamente para detectar fallos en la técnica y en el conocimiento, que predispongan al paciente a una complicación prevenible.

    2016-01-01

    Full Text Available En este artículo presentamos los resultados de un estudio cuyo objetivo fue describir las representaciones sociales del apego de 38 educadoras de párvulos pertenecientes a la Junta Nacional de Jardines Infantiles. Concretamente nos propusimos describir el significado que tiene el concepto apego para las educadoras de párvulos, e identificar los criterios de valoración del apego que ellas manifiestan. El estudio es cualitativo-descriptivo. Aplicamos entrevistas semiestructuradas y grupos focales. Los hallazgos destacan el manejo inapropiado acerca de la teoría del apego en las educadoras, lo que afecta en el dominio del contenido disciplinario para tomar decisiones metodológicas en sus prácticas profesionales. Las percepciones de las educadoras son de tipo social, vivencial y clasificatorio, significando el apego como proceso relacional que deja huellas en tanto vínculo afectivo perdurable.

    Full Text Available Este artículo detalla el proceso de elaboración y baremación del "Cuestionario de Apego Adulto". Un total de 445 sujetos, 159 hombres y 286 mujeres con una media de 30,5 años cumplimentaron el cuestionario original. Los análisis factoriales mostraron la solución de 4 factores como la más idónea, con un total de 40 ítems. Estos factores fueron: Baja autoestima, necesidad de aprobación y miedo al rechazo, Resolución hostil de conflictos, rencor y posesividad, Expresión de sentimientos y comodidad con las relaciones y Autosuficiencia emocional e incomodidad con la intimidad. Para establecer tipologías se realizaron análisis de conglomerados. La solución de dos clusters clasificó a los sujetos en seguros e inseguros, y la solución de cuatro en seguros, preocupados, alejados y temerosos hostiles. Nuestros resultados identifican un estilo temeroso algo diferente al de Bartholomew y Horowitz (1991. Se discuten las particularidades de los estilos afectivos y sus propiedades psicométricas.

    Full Text Available Se presenta los resultados obtenidos por los Centros de Desarrollo Infantil Temprano (DIT en familias con vulnerabilidad psicosocial. Mediante un estudio longitudinal no experimental, se observó una mejoría estadísticamente significativa en el desarrollo psicomotor infantil, identificándose en el EEDP un efecto preventivo para casos con normalidad inicial y un efecto nivelador para casos en riesgo inicial (n=166, p<0.05. Asimismo, se observó un aumento en la proporción de casos clasificados con apego seguro en el ADS y de disminución de aquellos con apego evitativo (n=49, p<0.01. Si bien no pueden atribuirse vínculos causales con la intervención, los datos aportan evidencia que respalda la labor realizada por los Centros DIT e incentivan a desarrollar nuevas investigaciones en programas de intervención temprana en la realidad latinoamericana.

    Full Text Available El objetivo de este estudio es analizar la relación existente entre la disposición al riesgo en las relaciones sexuales en personas adolescentes y variables afectivo-emocionales tales como el apego a la madre, al padre, a los iguales, los estilos de apego y las dificultades de regulación emocional. Han participado 1911 adolescentes escolarizados, de ambos sexos, entre 15 y 20 años. Los resultados indican que la seguridad del apego se relaciona inversamente con la disposición al riesgo en las relaciones sexuales, mientras que las dificultades de regulación muestran una asociación positiva, con diferencias entre sujetos sexualmente activos y no activos. Se han hallado diferencias por género, y por categorías de apego, así como entre las personas sexualmente activas y no activas.

    Full Text Available A teoria do apego tem como premissas que o apego da pessoa está relacionado à qualidade das suas relações amorosas e que tende a ser reativado em situações estressantes. Baseado nisso, esse estudo investigou as relações entre apego individual e apego compartilhado pelos cônjuges, em três casais, cujo filho apresenta o Transtorno do Espectro do Autismo -TEA. O apego individual foi avaliado através do Attachment Script Assessment e o apego compartilhado, através de uma entrevista semiestruturada. Os principais resultados revelaram que em casais, nos quais um (ou ambos dos cônjuges, apresentaram acesso ao script de apego individual seguro, a relação como parceiros, principalmente no aspecto parental, estava preservada, o que não ocorreu quando os cônjuges não apresentaram estes indicadores.

    Full Text Available Se estudia la relación entre apego y psicopatología en una muestra de 40 adolescentes y jóvenes que han sufrido maltrato intrafamiliar. El apego se evalúa mediante el cuestionario RQ de Bartholomew, que distingue cuatro estilos de apego en función de la imagen positiva o negativa del self y de los demás: apego seguro, preocupado, temeroso y evitativo. Los resultados del estudio muestran que el apego inseguro, sobre todo el subtipo evitativo, es el más prevalente. Algo más de la mitad de la muestra (52.5% presenta sintomatología clínicamente significativa (evaluada mediante el SCL-90-R, en especial hostilidad, obsesión-compulsión, ideación paranoide, psicoticismo y sensibilidad interpersonal. Los estilos de apego con una visión negativa del self (preocupado y temeroso tienden a presentar más sintomatología psicopatológica. Se discuten las implicaciones clínicas de estos resultados.

    2012-07-01

    Full Text Available El presente artículo realiza una revisión de la literatura sobre la influencia del maltrato infantil en la conformación de las representaciones del apego. Se describen los principales postulados teóricos respecto de los efectos del maltrato en los procesos defensivos, los sistemas de memoria y las estrategias de apego, elementos discutidos a través de la presentación de un modelo integrativo, el cual es contrastado con estudios empíricos. Se constata que el maltrato infantil afecta la calidad de las representaciones del apego, sin embargo se aprecia que los estudios no logran dar cuenta de toda la complejidad del fenómeno del maltrato. Los postulados teóricos abordados en este trabajo son marginalmente puestos a prueba en las investigaciones que se reportan.

    2017-01-01

    Full Text Available Se presenta una revisión de la literatura empírica cuyo objetivo es describir y comparar los hallazgos de los estudios que relacionan apego con autorregulación en la infancia. Se demuestra que el diseño metodológico y la técnica de medición utilizada para evaluar tanto apego como autorregulación afectan los resultados obtenidos. El lapso temporal entre mediciones afecta los resultados en estudios longitudinales de autorregulación conductual, y la técnica de evaluación del apego afecta el resultado en investigaciones de autorregulación emocional. Los resultados coinciden en describir una relación entre patrones de apego y el uso de estrategias de autorregulación emocional, lo que no se replica para la relación entre apego y emocionalidad. Se alerta sobre cómo los diseños metodológicos afectan los resultados de las investigaciones y se propende por la utilización de conceptualizaciones más holística de autorregulación.

Se realizaron análisis de vías, empleando ecuaciones estructurales, para estimar los efectos de variables del individuo y de su pareja sobre la satisfacción de cada miembro de la pareja con la relación. Se encontró que la relación entre dimensiones del apego y satisfacción se encuentra mediada, al menos parcialmente, por atribuciones tanto de causalidad como de responsabilidad. Los resultados indicaron diferentes patrones de asociación entre variables para hombres y mujeres.

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available El vínculo de apego ha mostrado ser un factor de vulnerabilidad para las enfermedades crónicas. El presente artículo busca clarificar esta relación mediante la teoría de la alóstasis. La teoría de la alóstasis hace referencia a la regulación de los procesos fisiológicos corporales complejos en el tiempo mediante una respuesta sistémica que mantiene la estabilidad fisiológica cuando se confronta la persona con cambios o retos. Los apegos inseguros confrontan a los niños desde sus primeros años con eventos estresantes, al no brindar al niño la seguridad sentida, finalidad fundamental del apego. De esta forma los apegos inseguros podrían tener impacto en la calibración del sistema de estrés en la edad temprana y serían factores de aumento de la carga alostática mediante mayores eventos vitales estresantes que las personas con apego seguro, una valoración cognitiva de amenaza que lleva al desarrollo de la hipervigilancia y el impacto en los sistemas de regulación del estrés en el cuerpo.

La evaluación de las interacciones madre-bebé se llevó a cabo a través de observaciones naturalistas en las casas de las familias. Los resultados indicaron que el programa de atención alternativo para los bebés de bajo peso al nacer, el PMC, incrementa la sensibilidad materna y disminuye el efecto negativo de variables como la pobreza, la prematurez, la hospitalización y separación temprana, y la maternidad adolescente sobre la primera relación de apego. Se encontró además que el PMC no incrementa la posibilidad de establecer relaciones de apego inseguras entre los bebés y sus madres; al contrario, la participación en el PMC se constituyó como un factor de protección para éstas díadas. Los resultados proveen insumos útiles para el desarrollo de programas de prevenciónintervención dirigidos a poblaciones de alto riesgo, a la vez que contribuyen al fortalecimiento de conceptos, áreas de análisis y metodologías propias de la teoría del apego en el contexto colombiano

    Full Text Available La terminación anticipada del proceso desde la perspectiva de los sistemas procesales es manifestación del esquema inquisitivo porque implica la renuncia a la contradicción y al juicio público. En todo proceso, independientemente de que su terminación sea abreviada o no, el Estado debe probar mas allá de toda duda la responsabilidad del procesado. El control judicial a los procesos que terminan mediante aceptación de cargos o acuerdo implica el ejercicio material de la función de juzgamiento, lo que a su turno exige la comprobación de la prueba como fundamento de la condena. Las modalidades de acuerdo que implican la modificación de la imputación fáctica encuentran fundamento en el principio de oportunidad, lo que significa que su pertinencia debe apoyarse en consideraciones de política criminal desarrolladas legalmente.

Pues, sin duda, la enajenación de la Corona de los oficios municipales, especialmente los de regidores, conllevaba una peligrosa carga de independencia política personal del poseedor con respecto al Estado. Se trata de dos ideas exactamente divergentes en su concepción de la administración pública. Sin embargo, fueron de la mano durante todo el período que comprende la Edad Moderna, constituyendo éste uno de los aspectos de más interesante estudio sobre la Administración pública. En definitiva, la venta de oficios públicos en el municipio castellano tuvo una larga y ambigua existencia. Su partida de nacimiento se sitúa en la baja Edad Media, desapareciendo en los albores de la contemporaneidad española, esto es, con las cortes de Cádiz y su labor desmanteladora de los restos feudovasalláticos que aún pervivían en la estructura social y política del país.

    Hernán Salas Quintanal

    2013-12-01

    Full Text Available El presente texto contiene las reflexiones que, sobre el estudio de las formas de organización comunitaria en varias localidades de un municipio mexicano, los autores han tenido después de varias temporadas de campo periódicas entre los años 2008 y 2012. Se plantea una propuesta de análisis antropológico del sistema de cargos que incluye tanto a comunidades indígenas como no-indígenas. Partiendo del reconocimiento del sistema de cargos como una institución esencialmente heterogénea, se sugiere que, como hipótesis principal, tal institución alimenta una serie de mecanismos que, en sí mismos, potencian los escenarios de interacciones que protagonizan los miembros de la comunidad a través de un conjunto de roles de la siguiente manera: fomentan que los escenarios puedan ser protagonizados por el mayor número de miembros; propician que tales escenarios se articulen con la mayor frecuencia posible; todo ello con el acuerdo tácito entre protagonistas de que exista rotación de roles entre escenario y escenario. Con el objetivo de facilitar el análisis, tales mecanismos son categorizados en cuatro grandes dimensiones: política-judicial, económica, religiosa y social. A modo de reflexión final, los autores proponen la idea del “proyecto comunitario” como denominador común de lo observado y leído en cuanto a sistemas de cargos se refiere.

    A gestação no contexto do HIV/Aids é geralmente acompanhada de intensa ansiedade devido à possível transmissão materno infantil do vírus. Este estudo investigou o apego materno fetal em gestantes que viviam com HIV (n = 88), em comparação a gestantes não portadoras do vírus (n = 79), através da Escala de Apego Materno fetal. Os resultados não revelaram diferenças entre as gestantes quanto ao escore total de apego materno fetal. Entretanto, os dados sugerem que o apego materno fetal pode se ma...

    Vera Regina Röhnelt Ramires

    Full Text Available Este artigo propõe uma releitura de alguns conceitos da teoria do apego, especialmente os de apego, comportamento de apego e modelo representacional interno. Visa discutir tais conceitos à luz das concepções de Bowlby e de autores contemporâneos. A dicotomia entre comportamento e representação do apego é questionada, bem como a estabilidade e unicidade do modelo representacional interno, com base na análise das contribuições dos principais teóricos desse campo, especialmente na vertente psicanalítica. Discute-se a importância da dimensão representacional e seu papel regulador das emoções e organizador do self, as implicações desses papéis para a Psicologia Clínica e do Desenvolvimento e para futuros estudos.

    Full Text Available El turismo se ha encaminado hacia prácticas más sostenibles que respetan el medio ambiente y fomenta la conservación de los recursos naturales y culturales, además de mejorar el desarrollo socioeconómico de los residentes. Una de estas prácticas se realiza a través del ecoturismo. Así, el objetivo principal de esta investigación es analizar la percepción de los residentes de comunida-des rurales en zonas en vías de desarrollo hacia el desarrollo sostenible del ecoturismo y su apego a su comunidad rural. También se pretender analizar el conocimiento de los residentes hacia los recursos naturales y culturales de su provincia. El destino geográfico objeto de investigación ha sido República Dominicana, en concreto las comunidades rurales de Puerto Plata, donde los residentes se benefician de un turismo alternativo al dominante de sol y playa. Para alcanzar los objetivos se ha realizado una encuesta. Entre los principales resultados de este estudio se puede observar que existe una elevada percepción de los residentes hacia el desarrollo sostenible del ecoturismo, que los residentes muestran un apego elevado a su comunidad rural, y que en gran parte de ellos hay un desconocimiento sobre algunos de los recursos, lo que puede generar debi-lidades en el desarrollo del ecoturismo en la zona.

    Full Text Available Desde una perspectiva de género y etnia, este artículo aborda el cambio cultural en contextos indígenas y, de manera particular, aquellos cambios que afectan a la posición y condición de las mujeres indígenas. Para ello procuramos documentar los procesos que siguen algunos cambios culturales que representan la superación de la exclusión de las mujeres a determinados espacios, así como analizar los factores causales que han dado lugar a dichos cambios. Este análisis ofrece resultados que permitan concluir si las transformaciones ocurridas son producto de un verdadero cambio pro igualdad en las relaciones de género o si, por el contrario, no son más que la resignificación de la tradicional subordinación de género. El caso que aquí analizamos es el de la reciente y creciente participación de las mujeres en el sistema de cargos, una participación femenina que representa un cambio cultural en relación con la tradicional exclusión de las mujeres a dicha institución social y comunitaria.

    Full Text Available La población del barrio de El Arbolito colaboró con la riqueza argentífera de la ciudad de Pachuca desde finales del siglo XIX y hasta la década de los años setenta; sin embargo, su vocación minera ha ido cambiando junto al resto de la ciudad y las actividades de la gente se han orientado hacia el sector terciario. Este artículo da cuenta de los cambios materiales que se han verificado en el paisaje del barrio y de los significados que tienen para dos grupos de edad en los que se ha dividido a sus habitantes: por un lado a los jóvenes y por otro a los adultos. En este estudio se muestra que la población tiene apego o desapego al barrio dependiendo, entre otros, de la experiencia que le ha tocado vivir por el rango de edad al que pertenece. También con esos elementos materiales y con los significados que representan, los habitantes de El Arbolito construyen su identidad cultural.

    In order to facilitate the answer of the Comision Federal de Electricidad (CFE) to the requests of services of transmission of authorized or potential licensees, this organism devised the construction of matrices of charges that allow in a fast and direct way for specific transactions, to know the charges in which different types of transmission services incur classified by transport levels and by tension levels in which the service is asked for. These tables could be published in the media that might be judged advisable, in order that the applicant licensees have access to a preliminary estimation of the charges for the required services, without the need of going, for one first estimation, directly to the CFE for their calculation. This article presents the results of the development of a calculation tool that allows estimating, in a fast and efficient way, charges for transmission services between regions of the national electrical system.

    existence of bereavement amongst 400 employees of a public bank after a big reengineering process. The study was carried out three years after the changes occurred, since after this period of time the feeling of bereavement and grief should have given place to the recovering process, with a predominance of states of positive spirit. The data suggests the existence of a pathological state of bereavement, with strong attachment to previous situations to change. It points out that it is not enough to prepare people to organizational changes that are coming and are inevitable. It is necessary to give them conditions so they can elaborate the feeling of grief in situations that already happened and were part of their lives. It is necessary to give them the opportunity to ‘say goodbye’ to past things, so that they can embrace the new ones.RESUMENGlobalización, tecnología y cambios sociales han contribuido al surgimiento de nuevos mercados y competidores, creando mayor competitividad. En contrapartida, se requiere de las personas flexibilidad para adaptarse a los constantes cambios y minimización del apego a situaciones pasadas. Sin embargo las rupturas que se exigen en los cambios pueden percibirse como muertes simbólicas, frente a su condición de irreversibilidad a los estados anteriores; esto genera estados de luto entre los involucrados. Partiendo del planteamiento etológico con relación al luto, este estudio analiza la existencia de estado de luto en 400 empleados de un banco estatal después de un importante proceso de reestructuración. El estudio se realizó tres años después de los cambios, momento en que después de este tiempo el sentimiento de luto por las pérdidas ya debería haber dado lugar a procesos de recuperación, con predominancia de estados de ánimo positivos. Los datos indican la existencia de estado de luto patológico, con fuerte apego a las situaciones anteriores al cambio. Esto señala que no basta preparar a las personas para los cambios

    Directory of Open Access Journals (Sweden)

    Sérgio C. Benício de Mello

    Full Text Available O valor do cliente tem merecido atenção especial de acadêmicos e profissionais de marketing. Um relevante estudo de Leão e Mello sobre o tema identifica sete valores pessoais dos clientes, um dos quais não é previsto naliteratura especializada, sendo chamado por esses autores de "sentimento de apego". Pela importância dessa"descoberta" para a efetiva compreensão do tema, é proposto aqui que sejam entendidas as reais motivações por trás dessa nova variável. Para isso, este artigo não está baseado apenas no relatório original da referida pesquisa (LEÃO, 2001, mas também em artigos publicados posteriormente (LEÃO e MELLO, 2001, 2002 e 2003, tendo como corpus as entrevistas nas quais foi identificado o referido "sentimento de apego". Os autores deste artigo recorreram à análise de discurso para a observação dos dados levantados, os quais revelam a"busca por segurança", a "fuga da solidão" e "a questão da identidade" como fundamentos do "sentimento de apego". A conclusão é a de que o valor descoberto é um produto da chamada "pós-modernidade".

    As a complement to passive detection systems, radiographic inspection of cargo is an increasingly important tool for homeland security because it has the potential to detect highly attenuating objects associated with special nuclear material or surrounding shielding, in addition to screening for items such as drugs or contraband. Radiographic detection of such threat objects relies on high image contrast between regions of different density and atomic number (Z). Threat detection is affected by scatter of the interrogating beam in the cargo, the radiographic system itself, and the surrounding environment, which degrades image contrast. Here, we estimate the extent to which scatter plays a role in radiographic imaging of cargo containers. Stochastic transport simulations were performed to determine the details of the radiography equipment and surrounding environment, which are important in reproducing measured data and to investigate scatter magnitudes for typical cargo. We find that scatter plays a stronger role in cargo radiography than in typical medical imaging scenarios, even for low-density cargo, with scatter-to-primary ratios ranging from 0.14 for very low density cargo, to between 0.20 and 0.40 for typical cargo, and higher yet for dense cargo.

In such a way, the authors recognize the importance of heterogeneous institution into cargo system concept. So that, they suggest, as the main hypothesis, that cargo system creates several mechanisms, which promote that members of the community stimulated social interactions’ scenes into role set. First, the community institutions promote the participation of the largest number of people. Second, interactions’ scenes are constantly created and recreated by the community members. Third, the roles’ rotation, as a product of a tacit agreement into community members, is fundamental to assure social participation, scene by scene. In order to facilitate the analysis, such mechanisms have been categorised in four larger dimensions: political-judicial, economic, religious and social. As a final thought, the idea of a communitarian project becomes the common characteristic of all the studied communities.

    2014-01-01

    The Logistics Reduction (LR) project within the Advanced Exploration Systems (AES) program is tasked with reducing logistical mass and repurposing logistical items. Multipurpose Cargo Transfer Bags (MCTB) have been designed such that they can serve the same purpose as a Cargo Transfer Bag, the suitcase-shaped common logistics carrying bag for Shuttle and the International Space Station. After use as a cargo carrier, a regular CTB becomes trash, whereas the MCTB can be unzipped, unsnapped, and unfolded to be reused. Reuse ideas that have been investigated include partitions, crew quarters, solar radiation storm shelters, acoustic blankets, and forward osmosis water processing.

  3. “Amigos con beneficios”: salud sexual y estilos de apego de hombres y mujeres

    Directory of Open Access Journals (Sweden)

    Herenia García Serrán

    Full Text Available Resumen Este estudio pretende analizar las variables relacionadas con la salud sexual de los individuos que pueden tener un impacto negativo en la asunción de riesgos - el uso de preservativo y el consumo de alcohol -; también pretende describir la prevalencia de infecciones de transmisión sexual y los estilos de apego que manifiestan hombres y mujeres en el marco relacional de amigos con beneficios. Para ello, se realiza un estudio transversal descriptivo. La información fue recogida mediante un cuestionario en línea y la escala de evaluación de los estilos de apego de Casullo y Fernández Liporace. En total, una muestra de 119 personas inmersas en una relación sexual casual con un amigo cumplimentaron el cuestionario. En relación a los resultados, casi el 30% de los participantes no han utilizado el preservativo en sus relaciones sexuales aduciendo razones asociadas al displacer e incomodidad; son las mujeres las que más padecen de infecciones de transmisión sexual; el consumo de alcohol ha constituido una práctica habitual en este tipo de relación. Aunque el apego seguro ha sido el más elevado, las mujeres se han mostrado temerosas. Amigos con beneficios puede entrañar graves consecuencias para la salud de los individuos y especialmente para las mujeres. Estos resultados recomiendan que desde la salud pública se preste atención a este novedoso vínculo sexual, así como la puesta en marcha de estrategias de promoción de la salud sexual dirigidas a las prácticas de riesgo de esta relación y a la mayor fragilidad afectiva y sexual de la mujer.

    Full Text Available In this work we consider a specific problem of optimal planning of maritime transportation of multiproduct cargo by ships of one (corporate strategy or several (partially corporate strategy companies: the core of the problem consists of the existence of the network of intermediate seaports (i.e. transitional seaports, where for every ship arrived the cargo handling is done, and which are situated between the starting and the finishing seaports. In this work, there are mathematical models built from scratch in the form of multicriteria optimization problem; then the goal attainment method of Gembicki is used for reducing the built models to a one-criterion problem of linear programming.

Se realizó un estudio transversal, con diseño no experimental y muestra de conveniencia, basado en mediciones de auto-reporte del Experiences in Close Relationships y el Marital Satisfaction Scale. Mediante ANOVA factorial, los resultados indican que las personas con estilo de apego seguro son las que reportan los niveles de satisfacción más altos y las con estilos desentendidos, los más bajos. En las díadas la combinación de ambos miembros de la pareja con estilos seguros es la que está asociada a los niveles de satisfacción más altos y la combinación desentendido-temeroso, a los más bajos. No hubo diferencias en la satisfacción según sexo, edad, escolaridad, afiliación religiosa, presencia de hijos ni tiempo de la relación marital.The aim of the study was to evaluate differences in marital satisfaction according to attachment styles and the interaction between the individual and the partner's attachment styles in a sample of 129 participants and their partners, all of them residing in the city of Antofagasta, Chile.

    2009-12-01

    Richard Feynman, in one of his famous rants, evoked as a metaphor what he called "cargo-cult science". During the Second World War, the indigenous people of the South Pacific became accustomed to US Air Force planes landing on their islands, invariably bringing a profusion of desirable goods and tasty foods. When the war ended, they were distressed by the discontinuation of this popular service. So, they decided to take action. They cleared elongated patches of land to make them look like runways. They lit wood fires where they had seen electric floodlights guiding in the planes. They built a wooden shack and made a man sit inside with two halves of a coconut on each ear and bamboo bars sticking out like antennas: he was the "air controller". And they waited for the planes to return.

    Full Text Available O objetivo deste estudo é apresentar, de maneira didática, a perspectiva evolucionária no estudo do comportamento humano. Para isso, apresenta-se a etologia, apontando algumas variações nas perspectivas de estudo da área. A etologia surgiu com o objetivo de estudar os comportamentos inatos nas diversas espécies em ambiente natural. Atualmente pode-se falar em duas tendências: a etologia tradicional e a ecologia comportamental, preocupadas, respectivamente, com as causas imediatas e evolutivas do comportamento. Superando concepções dualistas como inato-aprendido e natureza-cultura, a etologia tem contribuído para a compreensão do comportamento humano. Neste artigo, apresenta-se como exemplo o desenvolvimento do apego, relacionando pressões seletivas, neotenia, cuidados parentais e o surgimento da instituição familiar.The purpose of this paper is to present, in a didactic manner an evolutionary perspective concerning the study of human behavior. In order to do this, an ethological perspective is given, indicating a number of variations in the study of the subject. Ethology first arose as the scientific study of innate behavior of different species that occurs in a natural environment. Currently we consider that there are two tendencies: a traditional ethology and a behavior ecology addressing immediate and evolutionary causes of behavior, respectively. Beyond the dualist concepts, innate-learned and nature-culture, ethology has contributed to the understanding of human behavior. In this paper, we have included the examples of the development of attachment and its relation with selective pressures, neoteny, parental care and the emergence of the family institution.

    Full Text Available Muitas Instituições de Ensino Superior (IES objetivam a confiança por parte do aluno; no entanto, poucos trabalhos têm buscado explorar o que isto pode ocasionar. Buscando essa compreensão, o presente estudo procurou testar o apego e a confiança e o apego como antecedentes da recomendação boca-a-boca em uma IES na modalidade a distância. Por meio de uma survey com a participação de 175 alunos do Ensino a Distância (EAD, verificou-se por equação estrutural, que a confiança na IES pode ser um antecedente do apego pela instituição e da propensão em recomendar a IES para outras pessoas por meio da propaganda boca-a-boca. Percebeu-se ainda, que a recomendação é mais influenciada pela confiança do que pelo apego

    The endoplasmic reticulum (ER) is the site of synthesis of secreted and membrane proteins. To exit the ER, proteins are packaged into COPII vesicles through direct interaction with the COPII coat or aided by specific cargo receptors. Despite the fundamental role of such cargo receptors in protein traffic, only a few have been identified; their cargo spectrum is unknown and the signals they recognize remain poorly understood. We present here an approach we term "PAIRS" (pairing analysis of cargo receptors), which combines systematic genetic manipulations of yeast with automated microscopy screening, to map the spectrum of cargo for a known receptor or to uncover a novel receptor for a particular cargo. Using PAIRS we followed the fate of ∼150 cargos on the background of mutations in nine putative cargo receptors and identified novel cargo for most of these receptors. Deletion of the Erv14 cargo receptor affected the widest range of cargo. Erv14 substrates have a wide array of functions and structures; however, they are all membrane-spanning proteins of the late secretory pathway or plasma membrane. Proteins residing in these organelles have longer transmembrane domains (TMDs). Detailed examination of one cargo supported the hypothesis that Erv14 dependency reflects the length rather than the sequence of the TMD. The PAIRS approach allowed us to uncover new cargo for known cargo receptors and to obtain an unbiased look at specificity in cargo selection. Obtaining the spectrum of cargo for a cargo receptor allows a novel perspective on its mode of action. The rules that appear to guide Erv14 substrate recognition suggest that sorting of membrane proteins at multiple points in the secretory pathway could depend on the physical properties of TMDs. Such a mechanism would allow diverse proteins to utilize a few receptors without the constraints of evolving location-specific sorting motifs.

  13. Cargo recognition and cargo-mediated regulation of unconventional myosins.

    Organized motions are hallmarks of living organisms. Such motions range from collective cell movements during development and muscle contractions at the macroscopic scale all the way down to cellular cargo (e.g., various biomolecules and organelles) transportation and mechanoforce sensing at more microscopic scales. Energy required for these biological motions is almost invariably provided by cellular chemical fuels in the form of nucleotide triphosphate. Biological systems have designed a group of nanoscale engines, known as molecular motors, to convert cellular chemical fuels into mechanical energy. Molecular motors come in various forms including cytoskeleton motors (myosin, kinesin, and dynein), nucleic-acid-based motors, cellular membrane-based rotary motors, and so on. The main focus of this Account is one subfamily of actin filament-based motors called unconventional myosins (other than muscle myosin II, the remaining myosins are collectively referred to as unconventional myosins). In general, myosins can use ATP to fuel two types of mechanomotions: dynamic tethering actin filaments with various cellular compartments or structures and actin filament-based intracellular transport. In contrast to rich knowledge accumulated over many decades on ATP hydrolyzing motor heads and their interactions with actin filaments, how various myosins recognize their specific cargoes and whether and how cargoes can in return regulate functions of motors are less understood. Nonetheless, a series of biochemical and structural investigations in the past few years, including works from our own laboratory, begin to shed lights on these latter questions. Some myosins (e.g., myosin-VI) can function both as cellular transporters and as mechanical tethers. To function as a processive transporter, myosins need to form dimers or multimers. To be a mechanical tether, a monomeric myosin is sufficient. It has been shown for myosin-VI that its cellular cargo proteins can play critical roles

  14. Cargo transport by several motors

    In cells, organelles and vesicles are usually transported by cooperation of several motor proteins, including plus-end directed motor kinesin and minus-end directed motor dynein. Many biophysical models have been constructed to understand the mechanism of this motion. However, so far, the basic principle about it remains unclosed. In this paper, based on the recent experimental results and existing theoretical models, a spider-like model is provided. In this model, each motor is regarded as a bead-spring system. The bead can bind to or unbind from the track stochastically, and step forward or backward with fixed step size L and force dependent transition rates. The spring connects the bead to cargo tightly. At any time, the position of cargo is determined by force balance condition. The obvious characteristics of our model are that, the motors interact with each other and they do not share the external load equally. Our results indicate, the stall force of cargo, under which the mean velocity of cargo vanishe...

    Nucleic acids are the natural cargo of viruses and key determinants that affect viral shell stability. In some cases the genome structurally reinforces the shell, whereas in others genome packaging causes internal pressure that can induce destabilization. Although it is possible to pack heterologous cargoes inside virus-derived shells, little is known about the physical determinants of these artificial nanocontainers' stability. Atomic force and three-dimensional cryo-electron microscopy provided mechanical and structural information about the physical mechanisms of viral cage stabilization beyond the mere presence/absence of cargos. We analyzed the effects of cargo-shell and cargo-cargo interactions on shell stability after encapsulating two types of proteinaceous payloads. While bound cargo to the inner capsid surface mechanically reinforced the capsid in a structural manner, unbound cargo diffusing freely within the shell cavity pressurized the cages up to ~30 atm due to steric effects. Strong cargo-cargo coupling reduces the resilience of these nanocompartments in ~20% when bound to the shell. Understanding the stability of artificially loaded nanocages will help to design more robust and durable molecular nanocontainers.Nucleic acids are the natural cargo of viruses and key determinants that affect viral shell stability.

    An active swimmer can tow a passive cargo by binding it to form a self-propelling dimer. The orientation of the cargo relative to the axis of the active dimer's head is determined by the hydrodynamic interactions associated with the propulsion mechanism of the latter. We show how the tower-cargo angular configuration greatly influences the dimer's diffusivity and, therefore, the efficiency of the active swimmer as a micro-towing motor.

    Full Text Available Esse artigo discute a possibilidade de articulação de conceitos da teoria do apego e da teoria da cognição social. Conceitos-chave de ambas as teorias são apresentados, procurando-se analisar algumas das suas interfaces. Ao assumirmos uma perspectiva epistemológica complexa, não linear, domínios teóricos tradicionalmente considerados antagônicos, como a teorização sobre o pensamento e aquelas sobre sentimentos têm se entrelaçado para a abordagem teórica e clínica de problemáticas recentes. Concluímos que essa articulação poderia criar um campo conceitual novo, o qual demanda pesquisas e uma teorização aprofundada, possuindo implicações para a compreensão do desenvolvimento infantil, para o âmbito da clínica psicológica e para o campo da construção do conhecimento.

En San Bernardino de Milpillas, Durango, los cargos de la Iglesia son diferentes a los del gobierno tradicional. Los segundos parecen apegarse más a las culturales locales, aunque los cargos de la Iglesia han sido objeto de transformaciones significativas para excluir a los ministros católicos en las ceremonias cristianas. La fiesta de la Candelaria, que precede a la toma de posesión de los nuevos “empleados”, muestra que los aspectos civiles de los cargos son indisociables de los rituales religiosos. Los cargos reunían funciones militares, judiciales y económicas, pero éstas han ido perdiendo vigencia por la violencia y por la compañía forestal, una notable fuente de recursos. Sin embargo, por el sistema de cargos los mestizos de Milpillas se han integrado a la organización política y la cultura de los tepehuanos.

    Understanding the mechanisms by which molecular motors coordinate their activities to transport vesicular cargoes within neurons requires the quantitative analysis of motor/cargo associations at the single vesicle level. The goal of this protocol is to use quantitative fluorescence microscopy to correlate ("map") the position and directionality of movement of live cargo to the composition and relative amounts of motors associated with the same cargo. "Cargo mapping" consists of live imaging of fluorescently labeled cargoes moving in axons cultured on microfluidic devices, followed by chemical fixation during recording of live movement, and subsequent immunofluorescence (IF) staining of the exact same axonal regions with antibodies against motors. Colocalization between cargoes and their associated motors is assessed by assigning sub-pixel position coordinates to motor and cargo channels, by fitting Gaussian functions to the diffraction-limited point spread functions representing individual fluorescent point sources. Fixed cargo and motor images are subsequently superimposed to plots of cargo movement, to "map" them to their tracked trajectories. The strength of this protocol is the combination of live and IF data to record both the transport of vesicular cargoes in live cells and to determine the motors associated to these exact same vesicles. This technique overcomes previous challenges that use biochemical methods to determine the average motor composition of purified heterogeneous bulk vesicle populations, as these methods do not reveal compositions on single moving cargoes. Furthermore, this protocol can be adapted for the analysis of other transport and/or trafficking pathways in other cell types to correlate the movement of individual intracellular structures with their protein composition. Limitations of this protocol are the relatively low throughput due to low transfection efficiencies of cultured primary neurons and a limited field of view available for

    Full Text Available El presente texto contiene una propuesta de análisis antropológico del sistema de cargos que incluye tanto a comunidades indígenas como no-indígenas. Partiendo del reconocimiento del sistema de cargos como una institución esencialmente heterogénea, se sugiere que, como hipótesis principal, tal institución alimenta una serie de mecanismos que, en sí mismos, potencian los escenarios de interacciones que protagonizan los miembros de la comunidad a través de un conjunto de roles: fomentan que los escenarios puedan ser protagonizados por el mayor número de miembros; propician que tales escenarios se articulen con la mayor frecuencia posible; todo ello con el acuerdo tácito entre protagonistas de que exista rotación de roles entre escenario y escenario. Esta propuesta analítica va a estar estructurada en tres bloques. En primer lugar, se ubican los fenómenos estudiados en torno al sistema de cargos en un continuum de comportamientos tendentes al individualismo y a lo colectivo en sus dos polos. En segundo lugar, se explicita el concepto de comunidad como elemento básico para el estudio de los sistemas de cargos; por último, se propone la idea del proyecto comunitario como denominador común en cuanto a sistemas de cargos se refiere en el área mesoamericana.

    Full Text Available A responsividade materna tem sido considerada como um elemento central para a compreensão do desenvolvimento infantil e este conceito tem sido articulado com a teoria do apego. Este artigo tem como objetivo discutir criticamente o papel de estudos transculturais sobre responsividade materna, à luz da teoria do apego, a partir da revisão da literatura recente sobre o tema. Considerando a teoria do apego um referencial valioso para investigações sobre interações mãe-bebê e responsividade materna, as conclusões apontam, basicamente, para três questões: 1 a teoria do apego precisa ser investigada em diferentes contextos socioculturais e receber validação transcultural; 2 pesquisas sobre responsividade materna devem considerar a discussão sobre a teoria do apego e diferenças culturais; 3 a inclusão do estudo da responsividade materna em referenciais teóricos que levem em conta variáveis socioculturais é necessária.Maternal responsiveness has been considered as an important concept for the understanding of different aspects of infant development, and this concept has been articulated with attachment theory. The objective of this article is to discuss critically the role of transcultural studies about maternal responsiveness, based on attachment theory, and to review of the recent literature about this subject. Considering attachment a valuable theoretical basis for investigations on mother-infant interactions and maternal responsiveness, the conclusions basically point to three issues: 1 the attachment theory needs to be investigated in different socio-cultural contexts, to be tested in its limits and to receive a transcultural validation; 2 research on maternal responsiveness should take into account the discussion on attachment theory and cultural differences; 3 the inclusion of the study of maternal responsiveness in a theoretical framework that takes into account socio-cultural variables is necessary.

    Full Text Available Through its history, one can see traces of African roots in the popular cult of San Baltazar in Argentina. In spite of starting as an imposed devotion by the clergy and the Spanish Crown to the slaves in the middle of 18th Century, early the later could insert their own cultural traditions, producing a sort of sui generis syncretism.Now days, those traditions are present in some religious ceremonies, especially in the devotional area. So far they consider that he is the patron saint of the joy and fun, they celebrate him with music and dance, being some of them from black roots. In this paper I wish to analyze one of these religious principles. So far there isn't any difference between kings and goods, the divine personality has a bipolar behavior that comes to real in a unique entity movable-non movable, thing- human. In this way, being goods also kings and kings also goods, their divine and royal attributes are object of devotion and subordination by their faithful people-subjects. My hypothesis is that that black people could have applied this principle so far they knew that double characteristic of this saint: divine (he is a saint and royal (he is one of the three Wise Men, compatible with their ancestral believes.//Al revisar la historia del culto popular de San Baltazar en Argentina, es posible encontrar sus raíces africanas.

  14. Research on probability distribution of port cargo throughput

    Institute of Scientific and Technical Information of China (English)

    SUN Liang; TAN De-rong

    2008-01-01

    In order to more accurately examine developing trends in gross cargo throughput, we have modeled the probability distribution of cargo throughput. Gross cargo throughput is determined by the time spent by cargo ships in the port and the operating efficiency of handling equipment. Gross cargo throughput is the sum of all compound variables determining each aspect of cargo throughput for every cargo ship arriving at the port. Probability distribution was determined using the Wald equation. The results show that the variability of gross cargo throughput primarily depends on the different times required by different cargo ships arriving at the port. This model overcomes the shortcoming of previous models: inability to accurately determine the probability of a specific value of future gross cargo throughput. Our proposed model of cargo throughput depends on the relationship between time required by a cargo ship arriving at the port and the operational capacity of handling equipment at the port. At the same time, key factors affecting gross cargo throughput are analyzed. In order to test the efficiency of the model, the cargo volume of a port in Shandong Province was used as an example. In the case study the actual results matched our theoretical analysis.

    2015-01-01

    The purpose of this study is twofold -- first, to introduce the application of high-order discontinuous Galerkin methods to buoyancy-driven cargo hold fire simulations, second, to explore statistical variation in the fluid dynamics of a cargo hold fire given parameterized uncertainty in the fire source location and temperature. Cargo hold fires represent a class of problems that require highly-accurate computational methods to simulate faithfully. Hence, we use an in-house discontinuous Galerkin code to treat these flows. Cargo hold fires also exhibit a large amount of uncertainty with respect to the boundary conditions. Thus, the second aim of this paper is to quantify the resulting uncertainty in the flow, using tools from the uncertainty quantification community to ensure that our efforts require a minimal number of simulations. We expect that the results of this study will provide statistical insight into the effects of fire location and temperature on cargo fires, and also assist in the optimization of f...

It pursues to improve the efficiency of the air cargo supply chain and to provide more information to the decision-makers to optimize their fields.Design/methodology/approach: The method used is a process simulation modelling software, WITNESS, which provides information to the decision-makers about the most relevant parameters subject to optimization. The input for the simulation is obtained from a qualitative analysis of the air cargo supply chain with the involved agents and from a study of the external trade by air mode, given that their behaviour depend on the location. The case study is focused on a particular location, the Case of Zaragoza Airport (Spain.Findings: This paper demonstrates that efficiency of the air cargo supply chain can increase by leveraging several parameters such as bottlenecks, resources or warehouses.Originality/value: It explores the use of a simulation modeling software originally intended for manufacturing processes and extended to support decision making processes in the area of air cargo.

  17. Cargo binding to Atg19 unmasks additional Atg8 binding sites to mediate membrane-cargo apposition during selective autophagy.

    2014-05-01

    Autophagy protects cells from harmful substances such as protein aggregates, damaged mitochondria and intracellular pathogens, and has been implicated in a variety of diseases. Selectivity of autophagic processes is mediated by cargo receptors that link cargo to Atg8 family proteins on the developing autophagosomal membrane. To avoid collateral degradation during constitutive autophagic pathways, the autophagic machinery must not only select cargo but also exclude non-cargo material. Here we show that cargo directly activates the cargo receptor Atg19 by exposing multiple Atg8 binding sites. Furthermore, Atg19 mediates tight apposition of the cargo and Atg8-coated membranes in a fully reconstituted system. These properties are essential for the function of Atg19 during selective autophagy in vivo. Our results suggest that cargo receptors contribute to tight membrane bending of the isolation membrane around the cargo.

    X-ray imaging can be used to inspect cargos imported into the United States. In order to better understand the performance of X-ray inspection systems, the X-ray characteristics (density, complexity) of cargo need to be quantified. In this project, an image complexity measure called integrated power spectral density (IPSD) was studied using both DNDO engineered cargos and stream-of-commerce (SOC) cargos. A joint distribution of cargo density and complexity was obtained. A support vector machine was used to classify the SOC cargos into four categories to estimate the relative fractions.

  19. Motility states in bidirectional cargo transport

    Klein, Sarah; Santen, Ludger

    2015-01-01

    Intracellular cargos which are transported by molecular motors move stochastically along cytoskeleton filaments. In particular for bidirectionally transported cargos it is an open question whether the characteristics of their motion can result from pure stochastic fluctuations or whether some coordination of the motors is needed. The results of a mean-field model of cargo-motors dynamics, which was proposed by M\\"uller et al.[1] suggest the existence of high motility states which would result from a stochastic tug-of-war. Here we analyze a non-mean field extension of their model, that takes explicitly the position of each motor into account. We find that high motility states then disappear. We consider also a mutual motor-motor activation, as an explicit mechanism of motor coordination. We show that the results of the mean-field model are recovered only in case of a strong motor-motor activation in the limit of a high number of motors.

    Klein, Sarah; Santen, Ludger

    2014-01-01

    We discuss a theoretical model for bidirectional cargo transport in biological cells, which is driven by teams of molecular motors and subject to thermal fluctuations. The model describes explicitly the directed motion of the molecular motors on the filament. The motor-cargo coupling is implemented via linear springs. By means of extensive Monte Carlo simulations we show that the model describes the experimentally observed regimes of anomalous diffusion, i.e. subdiffusive behavior at short times followed by superdiffusion at intermediate times. The model results indicate that subdiffuse regime is induced by thermal fluctuations while the superdiffusive motion is generated by correlations of the motors' activity. We also tested the efficiency of bidirectional cargo transport in crowded areas by measuring its ability to pass barriers with increased viscosity. Our results show a remarkable gain of efficiency for high viscosities.

  7. Stochastic Movement of Multiple Motor Transported Cargo

    Ando, David; Gopinathan, Ajay; Xu, Jing

    2015-03-01

    Experimental observations of cargo position during transport by multiple motors are determined by several coupled stochastic processes. During collective transport, each motor can transition between multiple kinetic states, with the state of each motor influencing the states of the others via mechanical coupling through a common cargo. We measured the motion of a micron sized bead as it is transported by two kinesin motors along a single microtubule track, focusing on cargo displacements which are both axial and transverse to the microtubule. We model the effects of inter-motor interference and the state of each motor throughout time, and back out motor properties using a systematic comparison of experimental observations with simulated model traces over a wide parameter space. Our model captures a surface-associated mode of kinesin, which is only accessible via inter-motor interference in groups, in which kinesin diffuses along the microtubule surface and rapidly ``hops'' between protofilaments without dissociating from the microtubule. This enhances local exploration of the microtubule surface, possibly enabling cellular cargos to overcome macromolecular crowding and to navigate obstacles along micro- tubule tracks without sacrificing overall travel distance.

    Prokaryotes mostly lack membranous compartments that are typical of eukaryotic cells, but instead, they have various protein-based organelles. These include bacterial microcompartments like the carboxysome and the virus-like nanocompartment encapsulin. Encapsulins have an adaptable mechanism for enzyme packaging, which makes it an attractive platform to carry a foreign protein cargo. Here we investigate the assembly pathways and mechanical properties of the cargo-free and cargo-loaded nanocompartments, using a combination of native mass spectrometry, atomic force microscopy and multiscale computational molecular modeling. We show that encapsulin dimers assemble into rigid single-enzyme bacterial containers. Moreover, we demonstrate that cargo encapsulation has a mechanical impact on the shell. The structural similarity of encapsulins to virus capsids is reflected in their mechanical properties. With these robust mechanical properties encapsulins provide a suitable platform for the development of nanotechnological applications.

    Johnson, Jesse; Santmire, Tara

    1999-01-01

    The purpose of the Aviation System Analysis Capability (ASAC) Air Cargo Investment Model-Cargo (ACIMC), is to examine the economic effects of technology investment on the air cargo market, particularly the market for new cargo aircraft. To do so, we have built an econometrically based model designed to operate like the ACIM. Two main drivers account for virtually all of the demand: the growth rate of the Gross Domestic Product (GDP) and changes in the fare yield (which is a proxy of the price charged or fare). These differences arise from a combination of the nature of air cargo demand and the peculiarities of the air cargo market. The net effect of these two factors are that sales of new cargo aircraft are much less sensitive to either increases in GDP or changes in the costs of labor, capital, fuel, materials, and energy associated with the production of new cargo aircraft than the sales of new passenger aircraft. This in conjunction with the relatively small size of the cargo aircraft market means technology improvements to the cargo aircraft will do relatively very little to spur increased sales of new cargo aircraft.

  6. Cargo adaptors: structures illuminate mechanisms regulating vesicle biogenesis.

    Science.gov (United States)

    Paczkowski, Jon E; Richardson, Brian C; Fromme, J Christopher

    2015-07-01

    Cargo adaptors sort transmembrane protein cargos into nascent vesicles by binding directly to their cytosolic domains. Recent studies have revealed previously unappreciated roles for cargo adaptors and regulatory mechanisms governing their function. The adaptor protein (AP)-1 and AP-2 clathrin adaptors switch between open and closed conformations that ensure they function at the right place at the right time. The exomer cargo adaptor has a direct role in remodeling the membrane for vesicle fission. Several different cargo adaptors functioning in distinct trafficking pathways at the Golgi are similarly regulated through bivalent binding to the ADP-ribosylation factor 1 (Arf1) GTPase, potentially enabling regulation by a threshold concentration of Arf1. Taken together, these studies highlight that cargo adaptors do more than just adapt cargos.

A amostra foi constituída por 403 adolescentes, entre os 14 e os 19 anos de idade. A análise univariada da variância mostrou que a estrutura familiar não prediz a auto-estima. Contudo, os estilos de apego aos pais derivados das análises de clusters e baseados no modelo bidimensional de Bartholomew foram associados à auto-estima , com níveis mais elevados para adolescentes de estilo seguro. A variância multivariada com o apego aos pais e aos pares como fatores independentes mostraram que o apego aos pares não desempenha um papel moderador na predição da auto-estima nos adolescentes. A regressão múltipla hierárquica indicou que uma elevada qualidade dos apegos aos pais e pares se mostram relevantes na predição da auto-estima.This study aimed to analyze the differential contribution to adolescent's self-esteem concerning family structure (intact and divorced families, interparental conflict, and attachment to parents and peers. The sample consisted of 403 adolescents, aged from 14 to 19. Univariate ANOVA showed that family structure does not predict self-esteem, but adolescents from intact families with higher levels of interparental conflict presented lower self-esteem. Parental attachment patterns derived from cluster analysis and based on Bartholomew bi-dimensional model were associated with self-esteem, namely, with higher levels for adolescents with a secure style. An ANOVA showed no moderation role in predicting adolescents' self-esteem, when attachment to parents and peers were considered as independent factors. On the other hand, multiple regression results indicated that high quality bonds to parents and peers are predictors of self-esteem.

  8. Cargo transportation by two species of motor protein.

    Science.gov (United States)

    Zhang, Yunxin

    2013-05-01

    The cargo motion in living cells transported by two species of motor protein with different intrinsic directionalities is discussed in this study. Similarly to single motor movement, the cargo steps forward and backward along a microtubule stochastically. Recent experiments found that cargo transportation by two motor species has a memory; it does not change its direction as frequently as expected, which means that its forward and backward step rates depend on its previous motion trajectory. By assuming that the cargo has only the least possible memory, i.e., its step direction depends only on the direction of its last step, two cases of cargo motion are analyzed in detail in this study: (I) cargo motion under constant external load, and (II) cargo motion in one fixed optical trap. Due to the existence of memory, in the first case, the cargo can keep moving in the same direction for a long distance. In the second case, the cargo will oscillate in the trap. The oscillation period decreases and the oscillation amplitude increases with increasing forward step rate of the motor, but both of them decrease with increasing trap stiffness. The most likely location of the cargo, where the probability of finding the oscillating cargo is maximum, may be the same as or may be different from the trap center, which depends on the step rates of the two motor species. Meanwhile, if the motors are robust, i.e., their forward to backward step rate ratios are high, there may be two such most likely locations, located one on each side of the trap center. The probability of finding the cargo in a given location, the probability of the cargo being in forward or backward motion, and various mean first passage times of the cargo to a given location or a given state are also analyzed.

  12. Basic mechanisms for recognition and transport of synaptic cargos

    Directory of Open Access Journals (Sweden)

    Schlager Max A

    2009-08-01

    Full Text Available Abstract Synaptic cargo trafficking is essential for synapse formation, function and plasticity. In order to transport synaptic cargo, such as synaptic vesicle precursors, mitochondria, neurotransmitter receptors and signaling proteins to their site of action, neurons make use of molecular motor proteins. These motors operate on the microtubule and actin cytoskeleton and are highly regulated so that different cargos can be transported to distinct synaptic specializations at both pre- and post-synaptic sites. How synaptic cargos achieve specificity, directionality and timing of transport is a developing area of investigation. Recent studies demonstrate that the docking of motors to their cargos is a key control point. Moreover, precise spatial and temporal regulation of motor-cargo interactions is important for transport specificity and cargo recruitment. Local signaling pathways – Ca2+ influx, CaMKII signaling and Rab GTPase activity – regulate motor activity and cargo release at synaptic locations. We discuss here how different motors recognize their synaptic cargo and how motor-cargo interactions are regulated by neuronal activity.

    Science.gov (United States)

    Harrison, Megan S; Hung, Chia-Sui; Liu, Ting-ting; Christiano, Romain; Walther, Tobias C; Burd, Christopher G

    2014-01-07

    Retromer is an evolutionarily conserved protein complex composed of the VPS26, VPS29, and VPS35 proteins that selects and packages cargo proteins into transport carriers that export cargo from the endosome. The mechanisms by which retromer is recruited to the endosome and captures cargo are unknown. We show that membrane recruitment of retromer is mediated by bivalent recognition of an effector of PI3K, SNX3, and the RAB7A GTPase, by the VPS35 retromer subunit. These bivalent interactions prime retromer to capture integral membrane cargo, which enhances membrane association of retromer and initiates cargo sorting. The role of RAB7A is severely impaired by a mutation, K157N, that causes Charcot-Marie-Tooth neuropathy 2B. The results elucidate minimal requirements for retromer assembly on the endosome membrane and reveal how PI3K and RAB signaling are coupled to initiate retromer-mediated cargo export.

    Full Text Available Purpose. Making the qualitative administrative decisions defining strategy and tactics of transport cargo complexes development, and also its subsystems, is possible only in the presence of flexible optimization model. This model has to consider multiparametricity and multicriteriality of the given task, uncertainty and vagueness of input information, and also to provide process automation of searching the best parameters of the given production facility. The purpose of the research is to develop procedures for the strategic management of complex with view of the most important factors and their stochastic nature, which will execute the improvement of technical equipment of TCC. Methodology. The problem of strategic management is based on solving the complex of issues of the optimal number of shunting locomotives, optimal processing capability of handling the front and rational capacity of warehouses. The problem is solved on the basis of the proposed optimality criterion – the specific set of profit per unit of capital assets of freight industry. The listed problems are solved using simulation modeling of the freight industry. Findings. The use of developed procedure allows one to improve the technical equipment of the freight stations and complexes. Originality. For the first time it was developed the procedure of strategic management of development. This procedure allows taking into account the probabilistic nature of demand for services of transport freight complexes and technological processes of client services on the complex stations. The proposed procedure can be applied during when planning the investments in the creation of transport freight complexes. Practical value. Use as a basic tool of simulation models of complex cargo operation allows estimating the effectiveness of the capital investments, the level of operating costs, as well as the quality of meeting the demands of potential customers in transportations at the stage of

  17. Environmental control of microtubule-based bidirectional cargo-transport

    Klein, Sarah; Santen, Ludger

    2014-01-01

    Inside cells, various cargos are transported by teams of molecular motors. Intriguingly, the motors involved generally have opposite pulling directions, and the resulting cargo dynamics is a biased stochastic motion. It is an open question how the cell can control this bias. Here we develop a model which takes explicitly into account the elastic coupling of the cargo with each motor. We show that bias can be simply controlled or even reversed in a counterintuitive manner via a change in the external force exerted on the cargo or a variation of the ATP binding rate to motors. Furthermore, the superdiffusive behavior found at short time scales indicates the emergence of motor cooperation induced by cargo-mediated coupling.

  20. Vacuolar transport in tobacco leaf epidermis cells involves a single route for soluble cargo and multiple routes for membrane cargo.

    Science.gov (United States)

    Bottanelli, Francesca; Foresti, Ombretta; Hanton, Sally; Denecke, Jürgen

    2011-08-01

    We tested if different classes of vacuolar cargo reach the vacuole via distinct mechanisms by interference at multiple steps along the transport route. We show that nucleotide-free mutants of low molecular weight GTPases, including Rab11, the Rab5 members Rha1 and Ara6, and the tonoplast-resident Rab7, caused induced secretion of both lytic and storage vacuolar cargo. In situ analysis in leaf epidermis cells indicates a sequential action of Rab11, Rab5, and Rab7 GTPases. Compared with Rab5 members, mutant Rab11 mediates an early transport defect interfering with the arrival of cargo at prevacuoles, while mutant Rab7 inhibits the final delivery to the vacuole and increases cargo levels in prevacuoles. In contrast with soluble cargo, membrane cargo may follow different routes. Tonoplast targeting of an α-TIP chimera was impaired by nucleotide-free Rha1, Ara6, and Rab7 similar to soluble cargo. By contrast, the tail-anchored tonoplast SNARE Vam3 shares only the Rab7-mediated vacuolar deposition step. The most marked difference was observed for the calcineurin binding protein CBL6, which was insensitive to all Rab mutants tested. Unlike soluble cargo, α-TIP and Vam3, CBL6 transport to the vacuole was COPII independent. The results indicate that soluble vacuolar proteins follow a single route to vacuoles, while membrane spanning proteins may use at least three different transport mechanisms.

    When the Transport Service is managing "exceptional cargo", the driver and the escort are often in charge of an operation involving equipment worth many hundred thousand francs. Equipment that may well be irreplaceable for a facility or an experiment.   The members of the Transport Service who carry out these tasks are very professional and are – needless to say – highly concentrated on the job. They count on your understanding and support in the traffic on site. Their convoys are – for good reasons – moving slowly. Kindly do not overtake, do not cut in in front of them and do not drive too closely. Respect the escort and do not position yourself between the truck and the escort vehicles. The EN department counts on your courtesy on the road.

    2005-02-09

    Factors affecting sensing of small quantities of fissionable material in large sea-going cargo containers by neutron interrogation and detection of {beta}-delayed photons are explored. The propagation of variable-energy neutrons in cargos, subsequent fission of hidden nuclear material and production of the {beta}-delayed photons, and the propagation of these photons to an external detector are considered explicitly. Detailed results of Monte Carlo simulations of these stages in representative cargos are presented. Analytical models are developed both as a basis for a quantitative understanding of the interrogation process and as a tool to allow ready extrapolation of the results to cases not specifically considered here.

  14. Stochastic modeling of cargo transport by teams of molecular motors

    CERN Document Server

    Klein, Sarah; Santen, Ludger

    2014-01-01

    Many different types of cellular cargos are transported bidirectionally along microtubules by teams of molecular motors. The motion of this cargo-motors system has been experimentally characterized in vivo as processive with rather persistent directionality. Different theoretical approaches have been suggested in order to explore the origin of this kind of motion. An effective theoretical approach, introduced by M\\"uller et al., describes the cargo dynamics as a tug-of-war between different kinds of motors. An alternative approach has been suggested recently by Kunwar et al., who considered the coupling between motor and cargo in more detail. Based on this framework we introduce a model considering single motor positions which we propagate in continuous time. Furthermore, we analyze the possible influence of the discrete time update schemes used in previous publications on the system's dynamic.

  16. Bidirectionality From Cargo Thermal Fluctuations in Motor-Mediated Transport

    CERN Document Server

    Miles, Christopher E

    2016-01-01

    Molecular motor proteins serve as an essential component of intracellular transport by generating forces to haul cargoes along cytoskeletal filaments. In some circumstances, two species of motors that are directed oppositely (e.g. kinesin, dynein) can be attached to the same cargo. The resulting net motion is known to be bidirectional, but the mechanism of switching remains unclear. In this work, we propose a mean-field mathematical model of the mechanical interactions of two populations of molecular motors with diffusion of the cargo (thermal fluctuations) as the fundamental noise source. By studying a simplified model, the delayed response of motors to rapid fluctuations in the cargo is quantified, allowing for the reduction of the full model to two "characteristic positions" of each of the motor populations. The system is then found to be "metastable", switching between two distinct directional transport states, or bidirectional motion. The time to switch between these states is then investigated using WKB...

    A large number of manned modules are being progressively launched to the International Space Station (ISS) and integrated on-orbit, required to be operated and maintained over long on-orbit stay time, supported by periodical servicing and supply.The European Space Agency (ESA), together with its several industrial aerospace contractors such as Alcatel Alenia Space, is deeply involved in development of space systems hardware, in planning and execution of mission operations, logistics and supply to ISS of consumables, payloads, scientific experiments, orbital replacement units up to station modules and infrastructures, as needed by the ISS utilization cycles. In this frame safety plays a significant role to assure that the safety of the systems is preserved throughout the ISS exploitation phase. This paper summarizes methods and requirements for the safety certification process being implemented to dry cargo integration and accommodation in Jules Verne, the 1st flight of the Automated Transfer Vehicle (ATV), one of the major ESA contributions to the utilization of ISS.

  19. Air Cargo Transportation Route Choice Analysis

    Obashi, Hiroshi; Kim, Tae-Seung; Oum, Tae Hoon

    2003-01-01

    Using a unique feature of air cargo transshipment data in the Northeast Asian region, this paper identifies the critical factors that determine the transshipment route choice. Taking advantage of the variations in the transport characteristics in each origin-destination airports pair, the paper uses a discrete choice model to describe the transshipping route choice decision made by an agent (i.e., freight forwarder, consolidator, and large shipper). The analysis incorporates two major factors, monetary cost (such as line-haul cost and landing fee) and time cost (i.e., aircraft turnaround time, including loading and unloading time, custom clearance time, and expected scheduled delay), along with other controls. The estimation method considers the presence of unobserved attributes, and corrects for resulting endogeneity by use of appropriate instrumental variables. Estimation results find that transshipment volumes are more sensitive to time cost, and that the reduction in aircraft turnaround time by 1 hour would be worth the increase in airport charges by more than $1000. Simulation exercises measures the impacts of alternative policy scenarios for a Korean airport, which has recently declared their intention to be a future regional hub in the Northeast Asian region. The results suggest that reducing aircraft turnaround time at the airport be an effective strategy, rather than subsidizing to reduce airport charges.

Los resultados obtenidos muestran que los estilos de crianza de apoyo y comunicación versus control negativo están directamente relacionados con las variables funcionales y disfuncionales del desarrollo. El control negativo aparece relacionado con la victimización. A su vez, las variables funcionales están directamente relacionadas tanto con la victimización como con el apego, mientras que las variables disfuncionales solo alcanzan una correlación significativa con la victimización. Finalmente se discuten los resultados y sus posibles implicaciones.

    We describe the results of a Monte Carlo simulation 10 investigate the feasibility of using a pulsed deuterium-tritium (D-T) neutron technique for active interrogation of special nuclear material in cargo containers. Time distributions of fission neutrons from highly enriched uranium induced by a pulsed D-T neutron source were calculated for cargo containers with different hydrogen contents. A simple detector system with polyethylene and cadmium was modeled to calculate the two-group neutron flux at the detector.

    There is a great variety of liquid chemicals, and many shipowners are not clear about the cargos their ships will carry at the early stage of the design and construction of chemical tankers. In addition, because of the inclination to choose low cost construction material due to cost concern, the sources of cargos that ships can carry are greatly limited and the operation efficiency will be influenced. What should we do to avoid such situations?

    Some simple structural modifications have been demonstrated to be effective in reducing aerodynamic drag on vehicles that have empty open cargo bays. The basic idea is to break up the airflow in a large open cargo bay by inserting panels to divide the bay into a series of smaller bays. In the case of a coal car, this involves inserting a small number (typically between two and four) of vertical full-depth or partial-depth panels.

    Shuttle orbiter launch vibration and acoustic environments for cargo bay/payload interfaces are predicted. Data acquired during Shuttle flight tests are compared with the preflight estimates. Vibration response data for payload attachment locations are presented, along with acoustic data in the form of noise-level spectra measured at various locations in the cargo bay and space averages of the noise levels. It is shown that the payload-bay vibration and acoustic environments are generally less severe than predicted.

    There has been tremendous progress towards the development of responsive polymers that are programmed to respond to an external stimulus such as light, pH and temperature. The unique combination of molecular packaging followed by slow, controlled release of molecular cargo is of particular importance for self-healing materials and the controlled release of drugs. While much focus and progress remains centred around synthetic carriers, viruses and virus-like particles can be considered ideal cargo carriers as they are intrinsically designed to package, protect and deliver nucleic acid cargo to host cells. Here, we report the encapsulation of a stimuli-responsive self-immolative polymer within virus-like assemblies of Cowpea Chlorotic Mottle Virus. Upon photo-irradiation, the self-immolative polymer undergoes a head-to-tail depolymerization into its monomeric subunits, resulting in the slow release of the molecular cargo. We propose that the liberated monomers are small enough to diffuse through the pores of the virus capsid shell and offer an alternative strategy for the controlled loading and unloading of the molecular cargo using viruses as cargo carriers.

    Full Text Available During a ferry flight, in a standard operation condition and at cruising level, a military cargo experienced a double hydraulic system failure due to a structural damage of the dual booster actuator. The booster actuator is the main component in mechanism of aileron’s deflection. The crew was able to arrange an emergency landing thanks to the spare oil onboard: load specialists refilled the hydraulic reservoirs. Due to safety concerns and in order to prevent the possibility of other similar incidents, a technical investigation took place. The study aimed to carry out the analysis of root causes of the actuator failure. The Booster actuator is composed mainly by the piston rod and its aluminum external case (AA7049. The assembly has two bronze caps on both ends. These are fixed in position by means of two retainers. At one end of the actuator case is placed a trunnion: a cylindrical protrusion used as a pivoting point on the aircraft. The fracture was located at one end of the case, on the trunnion side, in correspondence to the cap and over the retainer. One of the two fracture surfaces was found separated to the case and with the cap entangled inside. The fracture surfaces of the external case indicated fatigue crack growth followed by ductile separation. The failure analysis was performed by means of optical, metallographic, digital and electronic microscopy. The collected evidences showed a multiple initiation fracture mechanism. Moreover, 3D scanner reconstruction and numerical simulation demonstrated that dimensional non conformances and thermal loads caused an abnormal stress concentration. Stress concentration was located along the case assy outer surface where the fatigue crack originated. The progressive rupture mechanism grew under cyclical axial load due to the normal operations. Recommendations were issued in order to improve dimensional controls and assembly procedures during production and overhaul activities.

  11. Cargo binding activates myosin VIIA motor function in cells.

    Myosin VIIA, thought to be involved in human auditory function, is a gene responsible for human Usher syndrome type 1B, which causes hearing and visual loss. Recent studies have suggested that it can move processively if it forms a dimer. Nevertheless, it exists as a monomer in vitro, unlike the well-known two-headed processive myosin Va. Here we studied the molecular mechanism, which is currently unknown, of activating myosin VIIA as a cargo-transporting motor. Human myosin VIIA was present throughout cytosol, but it moved to the tip of filopodia upon the formation of dimer induced by dimer-inducing reagent. The forced dimer of myosin VIIA translocated its cargo molecule, MyRip, to the tip of filopodia, whereas myosin VIIA without the forced dimer-forming module does not translocate to the filopodial tips. These results suggest that dimer formation of myosin VIIA is important for its cargo-transporting activity. On the other hand, myosin VIIA without the forced dimerization module became translocated to the filopodial tips in the presence of cargo complex, i.e., MyRip/Rab27a, and transported its cargo complex to the tip. Coexpression of MyRip promoted the association of myosin VIIA to vesicles and the dimer formation. These results suggest that association of myosin VIIA monomers with membrane via the MyRip/Rab27a complex facilitates the cargo-transporting activity of myosin VIIA, which is achieved by cluster formation on the membrane, where it possibly forms a dimer. Present findings support that MyRip, a cargo molecule, functions as an activator of myosin VIIA transporter function.

    Detection of cross-border smuggling of illicit materials and contraband is a challenge that requires rapid, low-dose, and efficient radiographic technology. The work we describe here is derived from a technique which uses monoenergetic gamma rays from low energy nuclear reactions, such as {sup 11}B(d,nγ){sup 12}C, to perform radiographic analysis of shipping containers. Transmission ratios of multiple monoenergetic gamma lines resulting from several gamma producing nuclear reactions can be employed to detect materials of high atomic number (Z), the details of which will be described in a separate paper. Inherent in this particular nuclear reaction is the production of fast neutrons which could enable neutron radiography and further characterization of the effective-Z of the cargo, especially within the range of lower Z. Previous research efforts focused on the use of total neutron counts in combination with X-ray radiography to characterize the hydrogenous content of the cargo. We present a technique of performing transmitted neutron spectral analysis to reconstruct the effective Z and potentially the density of the cargo. This is made possible by the large differences in the energy dependence of neutron scattering cross-sections between hydrogenous materials and those of higher Z. These dependencies result in harder transmission spectra for hydrogenous cargoes than those of non-hydrogenous cargoes. Such observed differences can then be used to classify the cargo based on its hydrogenous content. The studies presented in this paper demonstrate that such techniques are feasible and can provide a contribution to cargo security, especially when used in concert with gamma radiography.

  17. Stokes Efficiency of Molecular Motor-Cargo Systems

    Directory of Open Access Journals (Sweden)

    Hongyun Wang

    2008-01-01

    Full Text Available A molecular motor utilizes chemical free energy to generate a unidirectional motion through the viscous fluid. In many experimental settings and biological settings, a molecular motor is elastically linked to a cargo. The stochastic motion of a molecular motor-cargo system is governed by a set of Langevin equations, each corresponding to an individual chemical occupancy state. The change of chemical occupancy state is modeled by a continuous time discrete space Markov process. The probability density of a motor-cargo system is governed by a two-dimensional Fokker-Planck equation. The operation of a molecular motor is dominated by high viscous friction and large thermal fluctuations from surrounding fluid. The instantaneous velocity of a molecular motor is highly stochastic: the past velocity is quickly damped by the viscous friction and the new velocity is quickly excited by bombardments of surrounding fluid molecules. Thus, the theory for macroscopic motors should not be applied directly to molecular motors without close examination. In particular, a molecular motor behaves differently working against a viscous drag than working against a conservative force. The Stokes efficiency was introduced to measure how efficiently a motor uses chemical free energy to drive against viscous drag. For a motor without cargo, it was proved that the Stokes efficiency is bounded by 100% [H. Wang and G. Oster, (2002]. Here, we present a proof for the general motor-cargo system.

    All eukaryotic cells including those of our own body contain complex transport systems based on molecular motors which walk along cytoskeletal filaments. These motors are rather small and make discrete mechanical steps with a step size of the order of 10 nm but are able to pull cargo particles over much larger distances, from micrometers up to meters. In vivo, the intracellular cargos include large membrane-bounded organelles, smaller vesicles, a subset of mRNAs, cytoskeletal filaments, and various protein building blocks, which are transported between different cell compartments. This cargo transport is usually performed by teams of motors. If all motors belong to the same molecular species, the cooperative action of the motors leads to uni-directional transport with a strongly increased run length and with a characteristic force dependence of the velocity distributions. If two antagonistic teams of motors pull on the same cargo particle, they perform a stochastic tug-of-war, which is characterized by a subtle force balance between the two motor teams and leads to several distinct patterns of bi-directional transport. So far, all experimental observations on bi-directional transport are consistent with such a tug-of-war. If many motors and/or cargo particles are transported along the filaments, one encounters various traffic phenomena. Depending on their mutual interactions and the compartment geometry, the motors form various spatio-temporal patterns such as traffic jams, and undergo nonequilibrium phase transitions between different patterns of transport.

    Cargo transport is an important biological mechanism by which cells locomote, self-organize, and actively transport organelles. This transport is mediated by the cytoskeletal network and molecular motors; however, it is not known how network self-organization and dynamics affect these transport processes. In order to develop a mechanistic understanding of cargo transport, we use a coarse-grained Brownian dynamics model that incorporates the dynamics of these networks, as well as experimentally determined motor properties. We will test these models with two experimental systems: (1) in vitro microtubule networks with kinesin-1 motors, and quantum dot cargos on recreated microtubule networks, and (2) an excellent model organism, the moss Physcomitrella patens, in which chloroplasts are transported via the microtubule network by means of kinesin-like proteins. Phenomenological network characterizations are made, both in vivo and in vitro, and cargo motility is characterized using Mean Squared Displacement (MSD) measurements. Our simulations shed light on the role of network density and motor properties on the observed transport behavior, and improve our understanding of cargo transport in cells.

Working out a generalized dynamic model of cargo fixation is rather a complicated problem not in the sense of solving differential equations systems but in the sense of presenting them as a complex mechanical system “cargo – pads – flexible elements – thrust bars”. Generalized dynamic model of cargo with pads observed that this model represents technology of joint work of flexible and thrust fastening means of cargo on rolling stock. In particular, on the basis of this model there can be obtained the technology models of joint work of flexible and elastic fastening means of cargo without pads of fastening flexible elements of cargo with pads without thrust bars and also flexible fastening elements of cargo without pads and thrust bars at asymmetrical and/or symmetrical allocation of cargo in the wagon. A specific feature (novelty feature of the proposed dynamic model is inclusion into the model of both cargo pads and thrust bars which are nailed to the wagon floor close to the butt and lateral sides of cargo.

    The Logistics Reduction (LR) project within Advanced Exploration Systems (AES) is tasked with reducing logistical mass and repurposing logistical items. Multipurpose Cargo Transfer Bags (MCTB) have been designed such that they can serve the same purpose as a Cargo Transfer Bag (CTB), the common logistics carrying bag for the International Space Station (ISS). After use as a cargo carrier, a regular CTB becomes trash, whereas the MCTB can be unfolded into a flat panel for reuse. Concepts and potential benefits for various MCTB applications will be discussed including partitions, crew quarters, solar radiation storm shelters, acoustic blankets, and forward osmosis water processing. Acoustic MCTBs are currently in use on ISS to reduce the noise generated by the T2 treadmill, which reaches the hazard limit at high speeds. The development of the AMCTB included identification of keep-out zones, acoustic properties, deployment considerations, and structural testing. Features developed for these considerations are applicable to MCTBs for all crew outfitting applications.

    The pallet is the load-carrying body between cargo and cargo-hold cabin. Due to the narrow space of cargo-hold cabin, it is difficult for workers to operate. During the installation process of the pallet, it can easily collide with cabin. Based on the installation technology of the pallet, the assembly process of pallet is simulated and analyzed in this paper. The main installation process includes the lifting of pallet, the process of pallet entering the cabin and the assembling of separating device. In the simulation, the practicability of tooling, the standing position of operators, visibility and accessibility of operations are analyzed to determine the risk points in the installation process of pallet. According to the simulation results, feasibility of pallet installation is verified, space requirements for installation are given, and position requirements and posture requirements of workers in the operation process can also be achieved.

    Full Text Available This research estimates the shared value created by constructing a hypothetical Hyperloop to transport cargo along 300 km in Northern Germany. Following Porter-Kramer (2011, we identified and evaluated eight factors that create shared value: travel speed, operating costs, safety, noise pollution, air pollution, climate effect/carbon footprint, separation effect/ property efficiency, and maintenance. Using official data compiled by several German institutes and organizations, we conducted comparative analysis to quantify and compare the abovementioned factors for Hyperloop and over-the-road cargo transport in Germany. Then, we monetized the individual and collective benefits of the shared value created by Hyperloop replacing a significant share of cargo transported by truck. Our findings indicate that the hypothetical Hyperloop project in Northern Germany would create €660 to €900 million of shared value annually. Our research method establishes a framework for assessing future transportation projects like Hyperloop, and our findings can be generalized to industrialized nations beyond Germany.

  7. Coupling of Active Motion and Advection Shapes Intracellular Cargo Transport

    CERN Document Server

    Trong, P Khuc; Goldstein, R E; 10.1103/PhysRevLett.109.028104

    2012-01-01

    Intracellular cargo transport can arise from passive diffusion, active motor-driven transport along cytoskeletal filament networks, and passive advection by fluid flows entrained by such motor/cargo motion. Active and advective transport are thus intrinsically coupled as related, yet different representations of the same underlying network structure. A reaction-advection-diffusion system is used here to show that this coupling affects the transport and localization of a passive tracer in a confined geometry. For sufficiently low diffusion, cargo localization to a target zone is optimized either by low reaction kinetics and decoupling of bound and unbound states, or by a mostly disordered cytoskeletal network with only weak directional bias. These generic results may help to rationalize subtle features of cytoskeletal networks, for example as observed for microtubules in fly oocytes.

  8. Optimizing an undulating magnetic microswimmer for cargo towing

    2016-06-01

    One of the promising capabilities of magnetic microswimmers is towing a cargo, which can be used for targeted drug delivery or performing tissue biopsy. A key question is what should be the optimal size ratio between the cargo and the swimmer's flexible tail. This question is addressed here for the simplest theoretical model of a magnetic microswimmer undergoing planar undulations—a spherical load connected by a torsion spring to a rigid slender link. The swimmer's dynamic is formulated and leading-order expressions for its motion are obtained explicitly under small-amplitude approximation. Optimal combinations of magnetic actuation frequency, torsion stiffness, and tail length for maximizing displacement, average speed, or energetic efficiency are obtained. The theoretical results are compared with reported experiments in several types of cargo-towing magnetic microswimmers.

    cargo sizes to the column generation framework is not straightforward, and we handle the flexible cargo sizes heuristically when solving the subproblems. This leads to convergence issues in the branch-and-price search tree, and the optimal solution cannot be guaranteed. Hence we have introduced a method...... that generates an upper bound on the optimal objective. We have compared our method with an a priori column generation approach, and our computational experiments on real world cases show that the Dantzig-Wolfe approach is faster than the a priori generation of columns, and we are able to deal with larger...

  3. Study on Alternative Cargo Launch Options from the Lunar Surface

    Energy Technology Data Exchange (ETDEWEB)

    Cheryl A. Blomberg; Zamir A. Zulkefli; Spencer W. Rich; Steven D. Howe

    2013-07-01

    In the future, there will be a need for constant cargo launches from Earth to Mars in order to build, and then sustain, a Martian base. Currently, chemical rockets are used for space launches. These are expensive and heavy due to the amount of necessary propellant. Nuclear thermal rockets (NTRs) are the next step in rocket design. Another alternative is to create a launcher on the lunar surface that uses magnetic levitation to launch cargo to Mars in order to minimize the amount of necessary propellant per mission. This paper investigates using nuclear power for six different cargo launching alternatives, as well as the orbital mechanics involved in launching cargo to a Martian base from the moon. Each alternative is compared to the other alternative launchers, as well as compared to using an NTR instead. This comparison is done on the basis of mass that must be shipped from Earth, the amount of necessary propellant, and the number of equivalent NTR launches. Of the options, a lunar coil launcher had a ship mass that is 12.7% less than the next best option and 17 NTR equivalent launches, making it the best of the presented six options.

  11. Screening Cargo Containers to Remove a Terrorist Threat

    Energy Technology Data Exchange (ETDEWEB)

    Hazi, A

    2005-09-20

    Each year some 48 million cargo containers move between the world's ports. More than 6 million of these enter the U.S., but only about 2 percent are opened and inspected when they arrive at U.S. seaports. The West Coast ports of Los Angeles-Long Beach, Oakland, and Seattle alone process 11,000 containers per day, or about 8 containers per minute. Because of this high traffic volume, U.S. seaports are especially vulnerable to a terrorist attack. Illicit radioactive materials could be hidden in any one of the cargo-filled containers that arrive at U.S. ports. Yet, searching every shipment would be bring legitimate commercial activities to a halt. Improving security at U.S. ports is thus one of the nation's most difficult technical and practical challenges because the systems developed for screening cargo must operate in concert with ongoing seaport activities. Working at this intersection of commerce and national security, Lawrence Livermore researchers are applying their expertise in radiation science and detection to develop improved technologies for detecting hidden radioactive materials. One new technology being designed and tested at the Laboratory is a neutron interrogation system for cargo containers. This system will quickly screen incoming shipments to ensure that nuclear materials such as plutonium and highly enriched uranium (HEU) are not smuggled into the U.S.

  16. Mars Hybrid Propulsion System Trajectory Analysis. Part II; Cargo Missions

    Science.gov (United States)

    Chai, Patrick R.; Merrill, Raymond G.; Qu, Min

    2015-01-01

    NASA's Human Spaceflight Architecture Team is developing a reusable hybrid transportation architecture in which both chemical and electric propulsion systems are used to send crew and cargo to Mars destinations such as Phobos, Deimos, the surface of Mars, and other orbits around Mars. By combining chemical and electrical propulsion into a single spaceship and applying each where it is more effective, the hybrid architecture enables a series of Mars trajectories that are more fuel-efficient than an all chemical architecture without significant increases in flight times. This paper shows the feasibility of the hybrid transportation architecture to pre-deploy cargo to Mars and Phobos in support of the Evolvable Mars Campaign crew missions. The analysis shows that the hybrid propulsion stage is able to deliver all of the current manifested payload to Phobos and Mars through the first three crew missions. The conjunction class trajectory also allows the hybrid propulsion stage to return to Earth in a timely fashion so it can be reused for additional cargo deployment. The 1,100 days total trip time allows the hybrid propulsion stage to deliver cargo to Mars every other Earth-Mars transit opportunity. For the first two Mars surface mission in the Evolvable Mars Campaign, the short trip time allows the hybrid propulsion stage to be reused for three round-trip journeys to Mars, which matches the hybrid propulsion stage's designed lifetime for three round-trip crew missions to the Martian sphere of influence.

    Mechanized silica nanoparticles, equipped with pillar[5]arene-[2]pseudorotaxane nanovalves, operate in biological media to trap cargos within their nanopores, but release them when the pH is lowered or a competitive binding agent is added. Although cargo size plays an important role in cargo loading, cargo charge-type does not appear to have any significant influence on the amount of cargo loading or its release. These findings open up the possibility of using pillar[n]arene and its derivatives for the formation of robust and dynamic nanosystems that are capable of performing useful functions.

  14. El sistema de prestaciones por hijo a cargo en España

    2006-04-01

    Full Text Available Child Benefit (prestaciones familiares por hijo a cargo is the only monetary, regular and direct allowance to contribute bringing up children in Spain. Therefore, the Family Allowance System might be seen as a privileged watchtower where it is possible to observe complex and dynamic relationships between the family, the State and the market. Moreover, it shows its influence on the wellbeing and on the dynamics of inclusion or exclusion. This paper analyzes the Spanish economic allowance addressed to children and its evolution since its last reform in 1990. The main goal is to contribute to our understanding of the compromise level acquired by the Spanish State for familycare. This study tries to draw where the limit between public and private areas is and which are the differences concerning the cost of chid bearing and education.

    Las prestaciones por hijo a cargo constituyen en España la única prestación de carácter monetario, periódico y directo que se otorga a nivel estatal para contribuir a los gastos generados por la crianza y educación de los hijos/as. Este hecho convierte al sistema de prestaciones en una privilegiada atalaya para observar las complejas y dinámicas relaciones que se dan entre familia, Estado y mercado en la canalización del bienestar y, por consiguiente, en las dinámicas de inclusión/exclusión de este mismo bienestar. En este artículo se analiza la evolución del sistema español de prestaciones económicas dirigidas a los hijos desde su última gran reforma en 1990, con la intención de que su estudio nos ayude a dilucidar qué grado de compromiso adquiere el Estado respecto a la atención a la familia, en qué lugar sitúa el límite entre el ámbito público y el ámbito privado, y dónde se incluye, entre esta diferenciación de esferas, la asunción del coste de la crianza y la educación de los hijos.

  18. Development of a Cargo Screening Process Simulator: A First Approach

    CERN Document Server

    Siebers, Peer-Olaf; Aickelin, Uwe

    2010-01-01

    The efficiency of current cargo screening processes at sea and air ports is largely unknown as few benchmarks exists against which they could be measured. Some manufacturers provide benchmarks for individual sensors but we found no benchmarks that take a holistic view of the overall screening procedures and no benchmarks that take operator variability into account. Just adding up resources and manpower used is not an effective way for assessing systems where human decision-making and operator compliance to rules play a vital role. Our aim is to develop a decision support tool (cargo-screening system simulator) that will map the right technology and manpower to the right commodity-threat combination in order to maximise detection rates. In this paper we present our ideas for developing such a system and highlight the research challenges we have identified. Then we introduce our first case study and report on the progress we have made so far.

  19. Variable Structure Control of Catastrophic Course in Airdropping Heavy Cargo

    2009-01-01

    The mathematical model of a transport aircraft would be subjected to a sudden change when heavy cargo is dropped off in airdropping, which exerts serious influences upon the safety of the aircraft. A variable structure controller is specially designed for handling the airdrop process. The nonlinear system is linearized by input-output feedback linearization using differential geometry theories. On this basis, an inner loop system for velocity and attitude tracking control is designed by using the exponentially approaching rule of the variable structure theory. The whole flight control system is integrated with the outer loop flight altitude control. Digital simulation evidences the applicability of the system to potentially catastrophic course in airdropping heavy cargo and provides robustness against system parameter perturbation.

    2008-01-01

    Numerous studies have been completed in the United States, but no commercial MagLev systems have been deployed. Outside the U.S., MagLev continues to attract funding for research, development and implementation. A brief review of recent global developments in MagLev technology is given followed by the status of MagLev in the U.S. The paper compares the cost of existing MagLev systems with other modes of transport, notes that the near-term focus of MagLev development in the U.S. should be for cargo, and suggests that future MagLev systems should be for very high speed cargo. The Los Angeles to Port of Los Angeles corridor is suggested as a first site for implementation. The benefits of MagLev are described along with suggestions on how to obtain funding.

  1. Advanced propulsion options for the Mars cargo mission

    Frisbee, Robert H.; Blandino, John J.; Sercel, Joel C.; Sargent, Mark S.; Gowda, Nandini

    1990-01-01

    Several advanced propulsion options for a split-mission piloted Mars exploration scenario are presented. The primary study focus is on identifying concepts that can reduce total initial mass in low earth orbit (IMLEO) for the cargo delivery portion of the mission; in addition, concepts that can reduce the trip time of the piloted option are assessed. The propulsion options considered are nuclear thermal propulsion, solar sails, multimegawatt-class nuclear electric propulsion, solar electric propulsion, magnetic sails, mass drivers, rail guns, solar thermal rockets, beamed-energy propulsion systems, and tethers. For the cargo mission, solar sails are found to provide the greatest mass savings over the baseline chemical system, although they suffer from having very long trip times; a good performance compromise between a low IMLEO and a short trip time can be obtained using multimegawatt-class nuclear electric propulsion systems.

  6. X-Ray Scan Detection for Cargo Integrity

    Valencia, Juan D.; Miller, Steven D.

    2011-04-18

    ABSTRACT The increase of terrorism and its global impact has made the determination of the contents of cargo containers a necessity. Existing technology allows non-intrusive inspections to determine the contents of a container rapidly and accurately. However, some cargo shipments are exempt from such inspections. Hence, there is a need for a technology that enables rapid and accurate means of detecting whether such containers were non-intrusively inspected. Non-intrusive inspections are most commonly performed utilizing high powered X-ray equipment. The challenge is creating a device that can detect short duration X-ray scans while maintaining a portable, battery powered, low cost, and easy to use platform. The Pacific Northwest National Laboratory (PNNL) has developed a methodology and prototype device focused on this challenge. The prototype, developed by PNNL, is a battery powered electronic device that continuously measures its X-ray and Gamma exposure, calculates the dose equivalent rate, and makes a determination of whether the device has been exposed to the amount of radiation experienced during an X-ray inspection. Once an inspection is detected, the device will record a timestamp of the event and relay the information to authorized personnel via a visual alert, USB connection, and/or wireless communication. The results of this research demonstrate that PNNL’s prototype device can be effective at determining whether a container was scanned by X-ray equipment typically used for cargo container inspections. This paper focuses on laboratory measurements and test results acquired with the PNNL prototype device using several X-ray radiation levels.

  11. Cargo transport by cytoplasmic Dynein can center embryonic centrosomes.

    Directory of Open Access Journals (Sweden)

    Rafael A Longoria

    Full Text Available To complete meiosis II in animal cells, the male DNA material needs to meet the female DNA material contained in the female pronucleus at the egg center, but it is not known how the male pronucleus, deposited by the sperm at the periphery of the cell, finds the cell center in large eggs. Pronucleus centering is an active process that appears to involve microtubules and molecular motors. For small and medium-sized cells, the force required to move the centrosome can arise from either microtubule pushing on the cortex, or cortically-attached dynein pulling on microtubules. However, in large cells, such as the fertilized Xenopus laevis embryo, where microtubules are too long to support pushing forces or they do not reach all boundaries before centrosome centering begins, a different force generating mechanism must exist. Here, we present a centrosome positioning model in which the cytosolic drag experienced by cargoes hauled by cytoplasmic dynein on the sperm aster microtubules can move the centrosome towards the cell's center. We find that small, fast cargoes (diameter ∼100 nm, cargo velocity ∼2 µm/s are sufficient to move the centrosome in the geometry of the Xenopus laevis embryo within the experimentally observed length and time scales.

  12. Diffusion-Limited Cargo Loading of an Engineered Protein Container.

    Zschoche, Reinhard; Hilvert, Donald

    2015-12-30

    The engineered bacterial nanocompartment AaLS-13 is a promising artificial encapsulation system that exploits electrostatic interactions for cargo loading. In order to study its ability to take up and retain guests, a pair of fluorescent proteins was developed which allows spectroscopic determination of the extent of encapsulation by Förster resonance energy transfer (FRET). The encapsulation process is generally complete within a second, suggesting low energetic barriers for proteins to cross the capsid shell. Formation of intermediate aggregates upon mixing host and guest in vitro complicates capsid loading at low ionic strength, but can be sidestepped by increasing salt concentrations or diluting the components. Encapsulation of guests is completely reversible, and the position of the equilibrium is easily tuned by varying the ionic strength. These results, which challenge the notion that AaLS-13 is a continuous rigid shell, provide valuable information about cargo loading that will guide ongoing efforts to engineer functional host-guest complexes. Moreover, it should be possible to adapt the protein FRET pair described in this report to characterize functional capsid-cargo complexes generated by other encapsulation systems.

    2017-01-01

    One of the key issues in the fight against the smuggling of goods has been the development of scanners for cargo inspection. X-ray-based radiographic system scanners are the most developed sensing modality. However, they are costly and use bulky sources that emit hazardous, ionizing radiation. Aiming to improve the probability of threat detection, an ultrasonic-based technique, capable of detecting the footprint of metallic containers or compartments concealed within the metallic structure of the inspected cargo, has been proposed. The system consists of an array of acoustic transceivers that is attached to the metallic structure-under-inspection, creating a guided acoustic Lamb wave. Reflections due to discontinuities are detected in the images, provided by an imaging algorithm. Taking into consideration that the majority of those images are sparse, this contribution analyzes the application of Compressed Sensing (CS) techniques in order to reduce the amount of measurements needed, thus achieving faster scanning, without compromising the detection capabilities of the system. A parametric study of the image quality, as a function of the samples needed in spatial and frequency domains, is presented, as well as the dependence on the sampling pattern. For this purpose, realistic cargo inspection scenarios have been simulated. PMID:28098841

    The non-intrusive inspection (NII) of consolidated air cargo carried on commercial passenger aircraft continues to be a technically challenging, high-priority requirement of the Department of Homeland Security's Science and Technology Directorate (DHS S&T), the Transportation Security Agency and the Federal Aviation Administration. The goal of deploying a screening system that can reliably and cost-effectively detect explosive threats in consolidated cargo without adversely affecting the flow of commerce will require significant technical advances that will take years to develop. To address this critical National Security need, the Battelle Memorial Institute (Battelle), under a Cooperative Research and Development Agreement (CRADA) with four of its associated US Department of Energy (DOE) National Laboratories (Oak Ridge, Pacific Northwest, Idaho, and Brookhaven), conducted a research and development initiative focused on identifying, evaluating, and integrating technologies for screening consolidated air cargo for the presence of explosive threats. Battelle invested $8.5M of internal research and development funds during fiscal years 2007 through 2009. The primary results of this effort are described in this document and can be summarized as follows: (1) Completed a gap analysis that identified threat signatures and observables, candidate technologies for detection, their current state of development, and provided recommendations for improvements to meet air cargo screening requirements. (2) Defined a Commodity/Threat/Detection matrix that focuses modeling and experimental efforts, identifies technology gaps and game-changing opportunities, and provides a means of summarizing current and emerging capabilities.

  1. How molecular motors are arranged on a cargo is important for vesicular transport.

    The spatial organization of the cell depends upon intracellular trafficking of cargos hauled along microtubules and actin filaments by the molecular motor proteins kinesin, dynein, and myosin. Although much is known about how single motors function, there is significant evidence that cargos in vivo are carried by multiple motors. While some aspects of multiple motor function have received attention, how the cargo itself--and motor organization on the cargo--affects transport has not been considered. To address this, we have developed a three-dimensional Monte Carlo simulation of motors transporting a spherical cargo, subject to thermal fluctuations that produce both rotational and translational diffusion. We found that these fluctuations could exert a load on the motor(s), significantly decreasing the mean travel distance and velocity of large cargos, especially at large viscosities. In addition, the presence of the cargo could dramatically help the motor to bind productively to the microtubule: the relatively slow translational and rotational diffusion of moderately sized cargos gave the motors ample opportunity to bind to a microtubule before the motor/cargo ensemble diffuses out of range of that microtubule. For rapidly diffusing cargos, the probability of their binding to a microtubule was high if there were nearby microtubules that they could easily reach by translational diffusion. Our simulations found that one reason why motors may be approximately 100 nm long is to improve their 'on' rates when attached to comparably sized cargos. Finally, our results suggested that to efficiently regulate the number of active motors, motors should be clustered together rather than spread randomly over the surface of the cargo. While our simulation uses the specific parameters for kinesin, these effects result from generic properties of the motors, cargos, and filaments, so they should apply to other motors as well.

  6. ATHLETE: Lunar Cargo Handling for International Lunar Exploration

    Science.gov (United States)

    Wilcox, Brian H.

    2010-01-01

    As part of the Human-Robot Systems Project within the NASA Exploration Technology Development Program, the Jet Propulsion Laboratory is developing a vehicle called ATHLETE: the All-Terrain Hex-Limbed Extra-Terrestrial Explorer. The basic idea of ATHLETE is to have six relatively small wheels on the ends of legs. The small wheels and associated drive actuators are much less massive than the larger wheels and gears needed for an "all terrain" vehicle that cannot "walk" out of extreme terrain. The mass savings for the wheels and wheel actuators is greater than the mass penalty of the legs, for a net mass savings. Starting in 2009, NASA became engaged in detailed architectural studies for international discussions with the European Space Agency (ESA), the Japanese Space Agency (JAXA), and the Canadian Space Agency (CSA) under the auspices of the International Architecture Working Group (IAWG). ATHLETE is considered in most of the campaign options considered, providing a way to offload cargo from large Altair-class landers (having a cargo deck 6+ meters above the surface) as well as offloading international landers launched on Ariane-5 or H-2 launch vehicles. These international landers would carry provisions as well as scientific instruments and/or small rovers that would be used by international astronauts as part of an international effort to explore the moon.Work described in this paper includes architectural studies in support of the international missions as well as field testing of a half-scale ATHLETE prototype performing cargo offloading from a lander mockup, along with multi-kilometer traverse, climbing over greater than 1 m rocks, tool use, etc.

    2012-01-01

    This presentation will summarize the Cargo Airships for Northern Operations workshop that was held August 24-25, 2011. This workshop co-sponsored by NASA ARC and the Alaska State Department of Transportation was initiated by interest from Alaska Lt. Governor Mead Treadwell for assistance in investigating the potential benefits of proposed cargo airships for the Alaskan economy and societal needs. The workshop provided a brief background on the technology and operational aspects of conventional airships and hybrids followed by presentations on issues affecting cargo airship operations such as weather management, insurance, regulations, crew duty/rest rules, and available support infrastructures. Speakers representing potential cargo airship users from Alaskan State and commercial organizations presented the needs they felt could be met by cargo airship services. Presenters from Canadian private and military interests also detailed applications and missions that cargo airships could provide to remote regions of Canada. Cost drivers of cargo airship operations were also addressed and tools for modeling and analyzing operational factors and costs affecting cargo airship operations were discussed. Four breakout sessions were held which allowed workshop participants to contribute inputs to four topic areas: Business Approaches and Strategies (financing incentives public/private partnerships etc) for Airship Development and Operation, Design, Development, Production Challenges, and Possible Solutions, Regulatory, Certification, Legal, and Insurance Issues, and Operational Issues, Customer Requirements, and Airship Requirements. A follow on to the 2011 cargo airship workshop is being planned for July 31 August 2, 2012. A status update on this second workshop will also be presented.

    2013-03-01

    Full Text Available This study examines the delivering network of imported air express cargo as an integrated multi-depot vehicle routing problem. Integrated multi-depot vehicle routing problem attempts to decide which service centers should be used and how much freight should be unloaded in each service center. The role of an exchange point which is allowing the delivery vans and shuttles to exchange imported and exported goods is also addressed. Test results demonstrate the feasibility of the four models so these are highly promising for use in a diverse array of applications, such as in home delivery and reverse logistics.

    2014-01-01

    The swimming velocity and rate of dissipation of a linear chain consisting of two or three little spheres and a big sphere is studied on the basis of low Reynolds number hydrodynamics. The big sphere is treated as a passive cargo, driven by the tail of little spheres via hydrodynamic and direct elastic interaction. The fundamental solution of Stokes' equations in the presence of a sphere with no-slip boundary condition, as derived by Oseen, is used to model the hydrodynamic interactions between the big sphere and the little spheres.

    The problem consists of creating routes and schedules for a heterogeneous fleet of ships while determining the cargo routing and the speed for all relevant port pair/ship combinations. Transshipment is allowed in ports with transshipment capabilities. The service frequency is fixed at one week....... Since the speed of the ships is a decision variable, the developed model is nonlinear. The model is made linear by means of variable redefinition. Using decomposition the linearized model is split into a master problem and a sub problem per ship, and solved by a column generation algorithm....

    Zych, Noah; Silver, David; Stager, David; Green, Colin; Pilarski, Thomas; Fischer, Jacob

    2013-05-01

    The Cargo UGV project was initiated in 2010 with the aim of developing and experimenting with advanced autonomous vehicles capable of being integrated unobtrusively into manned logistics convoys. The intent was to validate two hypotheses in complex, operationally representative environments: first, that unmanned tactical wheeled vehicles provide a force protection advantage by creating standoff distance to warfighters during ambushes or improvised explosive device attacks; and second, that these UGVs serve as force multipliers by enabling a single operator to control multiple unmanned assets. To assess whether current state-of-the-art autonomous vehicle technology was sufficiently capable to permit resupply missions to be executed with decreased risk and reduced manpower, and to assess the effect of UGVs on customary convoy tactics, the Marine Corps Warfighting Laboratory and the Joint Ground Robotics Enterprise sponsored Oshkosh Defense and the National Robotics Engineering Center to equip two standard Marine Corps cargo trucks for autonomous operation. This paper details the system architecture, hardware implementation, and software modules developed to meet the vehicle control, perception, and planner requirements compelled by this application. Additionally, the design of a custom human machine interface and an accompanying training program are described, as is the creation of a realistic convoy simulation environment for rapid system development. Finally, results are conveyed from a warfighter experiment in which the effectiveness of the training program for novice operators was assessed, and the impact of the UGVs on convoy operations was observed in a variety of scenarios via direct comparison to a fully manned convoy.

  19. "Cargo-mooring" as an operating principle for molecular motors.

    Lisowski, Bartosz; Kuśmierz, Łukasz; Żabicki, Michał; Bier, Martin

    2015-06-07

    Navigating through an ever-changing and unsteady environment, and utilizing chemical energy, molecular motors transport the cell׳s crucial components, such as organelles and vesicles filled with neurotransmitter. They generate force and pull cargo, as they literally walk along the polymeric tracks, e.g. microtubules. What we suggest in this paper is that the motor protein is not really pulling its load. The load is subject to diffusion and the motor may be doing little else than rectifying the fluctuations, i.e. ratcheting the load׳s diffusion. Below we present a detailed model to show how such ratcheting can quantitatively account for observed data. The consequence of such a mechanism is the dependence of the transport׳s speed and efficacy not only on the motor, but also on the cargo (especially its size) and on the environment (i.e. its viscosity and structure). Current experimental works rarely provide this type of information for in vivo studies. We suggest that even small differences between assays can impact the outcome. Our results agree with those obtained in wet laboratories and provide novel insight in a molecular motor׳s functioning.

    The retromer complex 1, 2 is required for the sorting of acid hydrolases to lysosomes 3-7, transcytosis of the polymeric Ig receptor 8, Wnt gradient formation 9, 10, iron transporter recycling 11, and processing of the amyloid precursor protein 12. Human retromer consists of two smaller complexes, the cargo recognition Vps26:Vps29:Vps35 heterotrimer, and a membrane-targeting heterodimer or homodimer of SNX1 and/or SNX2 13. The crystal structure of a Vps29:Vps35 subcomplex shows how the metallophosphoesterase-fold subunit Vps29 14, 15 acts as a scaffold for the C-terminal half of Vps35. Vps35 forms a horseshoe-shaped right-handed α-helical solenoid whose concave face completely covers the metal-binding site of Vps29 and whose convex face exposes a series of hydrophobic interhelical grooves. Electron microscopy shows that the intact Vps26:Vps29:Vps35 complex is a stick-shaped, somewhat flexible, structure, ∼ 21 nm long. A hybrid structural model derived from crystal structures, electron microscopy, interaction studies, and bioinformatics shows that the α-solenoid fold extends the full length of Vps35, and that Vps26 is bound at the opposite end from Vps29. This extended structure presents multiple binding sites for the SNX complex and receptor cargo, and appears capable of flexing to conform to curved vesicular membranes. PMID:17891154

  1. Cargo and dynamin regulate clathrin-coated pit maturation.

    2009-03-01

    Full Text Available Total internal reflection fluorescence microscopy (TIR-FM has become a powerful tool for studying clathrin-mediated endocytosis. However, due to difficulties in tracking and quantifying their heterogeneous dynamic behavior, detailed analyses have been restricted to a limited number of selected clathrin-coated pits (CCPs. To identify intermediates in the formation of clathrin-coated vesicles and factors that regulate progression through these stages, we used particle-tracking software and statistical methods to establish an unbiased and complete inventory of all visible CCP trajectories. We identified three dynamically distinct CCP subpopulations: two short-lived subpopulations corresponding to aborted intermediates, and one longer-lived productive subpopulation. In a manner dependent on AP2 adaptor complexes, increasing cargo concentration significantly enhances the maturation efficiency of productive CCPs, but has only minor effects on their lifetimes. In contrast, small interfering RNA (siRNA depletion of dynamin-2 GTPase and reintroduction of wild-type or mutant dynamin-1 revealed dynamin's role in controlling the turnover of abortive intermediates and the rate of CCP maturation. From these data, we infer the existence of an endocytic restriction or checkpoint, responsive to cargo and regulated by dynamin.

  5. Spatial partitioning of secretory cargo from Golgi resident proteins in live cells

    Directory of Open Access Journals (Sweden)

    2001-10-01

    Full Text Available Abstract Background To maintain organelle integrity, resident proteins must segregate from itinerant cargo during secretory transport. However, Golgi resident enzymes must have intimate access to secretory cargo in order to carry out glycosylation reactions. The amount of cargo and associated membrane may be significant compared to the amount of Golgi membrane and resident protein, but upon Golgi exit, cargo and resident are efficiently sorted. How this occurs in live cells is not known. Results We observed partitioning of the fluorescent Golgi resident T2-CFP and fluorescent cargo proteins VSVG3-YFP or VSVG3-SP-YFP upon Golgi exit after a synchronous pulse of cargo was released from the ER. Golgi elements remained stable in overall size, shape and relative position as cargo emptied. Cargo segregated from resident rapidly by blebbing into micron-sized domains that contained little or no detectable resident protein and that appeared to be continuous with the parent Golgi element. Post-Golgi transport carriers (TCs exited repeatedly from these domains. Alternatively, entire cargo domains exited Golgi elements, forming large TCs that fused directly with the plasma membrane. However, domain formation did not appear to be an absolute prerequisite for TC exit, since TCs also exited directly from Golgi elements in the absence of large domains. Quantitative cargo-specific photobleaching experiments revealed transfer of cargo between Golgi regions, but no discrete intra-Golgi TCs were observed. Conclusions Our results establish domain formation via rapid lateral partitioning as a general cellular strategy for segregating different transmembrane proteins along the secretory pathway and provide a framework for consideration of molecular mechanisms of secretory transport.

  6. Effect of fuel concentration on cargo transport by a team of Kinesin motors

    Science.gov (United States)

    Takshak, Anjneya; Mishra, Nirvantosh; Kulkarni, Aditi; Kunwar, Ambarish

    2017-02-01

    Eukaryotic cells employ specialized proteins called molecular motors for transporting organelles and vesicles from one location to another in a regulated and directed manner. These molecular motors often work collectively in a team while transporting cargos. Molecular motors use cytoplasmic ATP as fuel, which is hydrolyzed to generate mechanical force. While the effect of ATP concentration on cargo transport by single Kinesin motor function is well understood, it is still unexplored, both theoretically and experimentally, how ATP concentration would affect cargo transport by a team of Kinesin motors. For instance, how does fuel concentration affect the travel distances and travel velocities of cargo? How cooperativity of Kinesin motors engaged on a cargo is affected by ATP concentration? To answer these questions, here we develop mechano-chemical models of cargo transport by a team of Kinesin motors. To develop these models we use experimentally-constrained mechano-chemical model of a single Kinesin motor as well as earlier developed mean-field and stochastic models of load sharing for cargo transport. Thus, our new models for cargo transport by a team of Kinesin motors include fuel concentration explicitly, which was not considered in earlier models. We make several interesting predictions which can be tested experimentally. For instance, the travel distances of cargos are very large at limited ATP concentrations in spite of very small travel velocity. Velocities of cargos driven by multiple Kinesin have a Michaelis-Menten dependence on ATP concentration. Similarly, cooperativity among the engaged Kinesin motors on the cargo shows a Michaelis-Menten type dependence, which attains a maximum value near physiological ATP concentrations. Our new results can be potentially useful in controlling artificial nano-molecular shuttles precisely for targeted delivery in various nano-technological applications.

    2017-01-01

    Vast numbers of proteins are transported into and out of the nuclei by approximately 20 species of importin-β family nucleocytoplasmic transport receptors. However, the significance of the multiple parallel transport pathways that the receptors constitute is poorly understood because only limited numbers of cargo proteins have been reported. Here, we identified cargo proteins specific to the 12 species of human import receptors with a high-throughput method that employs stable isotope labeling with amino acids in cell culture, an in vitro reconstituted transport system, and quantitative mass spectrometry. The identified cargoes illuminated the manner of cargo allocation to the receptors. The redundancies of the receptors vary widely depending on the cargo protein. Cargoes of the same receptor are functionally related to one another, and the predominant protein groups in the cargo cohorts differ among the receptors. Thus, the receptors are linked to distinct biological processes by the nature of their cargoes. DOI: http://dx.doi.org/10.7554/eLife.21184.001 PMID:28117667

  8. Co-operative versus independent transport of different cargoes by Kinesin-1.

    2008-05-01

    Kinesin motors drive the intracellular transport of multiple cargoes along microtubule tracks; yet, how kinesins discriminate among their many potential cargoes is unknown. We tested whether Kinesin-1 cargoes compete, co-operate or are transported independently of each other. We focused on Kinesin-1 cargoes that bind directly to the kinesin light chain (KLC) subunit, namely the c-Jun NH(2)-terminal kinase-interacting proteins (JIPs) 1 and 3, Kidins220/ARMS and PAT1. Overexpression of individual cargo proteins in differentiated CAD cells resulted in mislocalization of the endogenous protein but had no effect on localization of other cargo proteins to neurite tips. Thus, while transport of distinct cargoes is saturable, they do not compete with each other. Interestingly, we found that low expression of JIP1 or JIP3 enhanced the transport of the other JIP to neurite tips. Moreover, JIP1 and JIP3 require each other for transport. Co-operative transport is due to an interaction between JIP1 and JIP3 as well as distinct binding sites on the KLC tetratricopeptide repeat (TPR) bundle: the TPR groove binds to C-terminal residues of JIP1, whereas the TPR surface binds to internal residues in JIP3. Formation of a JIP1/JIP3/KLC complex is necessary for efficient JIP1 or JIP3 transport in neuronal cells. Thus, JIP scaffolding proteins are transported in a co-operative manner, despite the independent transport of other Kinesin-1 cargoes.

  9. A hopping mechanism for cargo transport by molecular motors in crowded microtubules

    CERN Document Server

    Goldman, Carla

    2010-01-01

    Most models designed to study the bidirectional movement of cargos as they are driven by molecular motors rely on the idea that motors of different polarities can be coordinated by external agents if arranged into a motor-cargo complex to perform the necessary work [gross04]. Although these models have provided us with important insights into these phenomena, there are still many unanswered questions regarding the mechanisms through which the movement of the complex takes place on crowded microtubules. For example (i) how does cargo-binding affect motor motility? and in connection with that - (ii) how does the presence of other motors (and also other cargos) on the microtubule affect the motility of the motor-cargo complex? We discuss these questions from a different perspective. The movement of a cargo is conceived here as a hopping process resulting from the transference of cargo between neighboring motors. In the light of this, we examine the conditions under which cargo might display bidirectional movemen...

    Using Networked RFID equipped in warehouse or supermarket distribution, Enterprise information system (EIS) can gather and deal with cargos information. Nevertheless, when cargos are in traffic, the Networked RFID can't monitor the cargos any more as the products tagged aren't within range of a reader. This paper proposes a solution framework which combines Networked RFID and GPS tracking, and then equip with this system in container to make the cargos monitored even if the cargos are in traffic. This solution can solve the accurate consignments, position tracking and advanced theft happening through drilling holes in container. In addition, customhouse and checkpoint can get an electronic shipment manifest rapidly and safely when a vehicle gets through a checkpoint.

  17. Structural Basis of Cargo Recognition by Unconventional Myosins in Cellular Trafficking.

    Science.gov (United States)

    Li, Jianchao; Lu, Qing; Zhang, Mingjie

    2016-08-01

    Unconventional myosins are a superfamily of actin-based molecular motors playing diverse roles including cellular trafficking, mechanical supports, force sensing and transmission, etc. The variable neck and tail domains of unconventional myosins function to bind to specific cargoes including proteins and lipid vesicles and thus are largely responsible for the diverse cellular functions of myosins in vivo. In addition, the tail regions, together with their cognate cargoes, can regulate activities of the motor heads. This review outlines the advances made in recent years on cargo recognition and cargo binding-induced regulation of the activity of several unconventional myosins including myosin-I, V, VI and X in cellular trafficking. We approach this topic by describing a series of high-resolution structures of the neck and tail domains of these unconventional myosins either alone or in complex with their specific cargoes, and by discussing potential implications of these structural studies on cellular trafficking of these myosin motors.

  18. VAMP4 Is an Essential Cargo Molecule for Activity-Dependent Bulk Endocytosis.

    2015-12-02

    The accurate formation of synaptic vesicles (SVs) and incorporation of their protein cargo during endocytosis is critical for the maintenance of neurotransmission. During intense neuronal activity, a transient and acute accumulation of SV cargo occurs at the plasma membrane. Activity-dependent bulk endocytosis (ADBE) is the dominant SV endocytosis mode under these conditions; however, it is currently unknown how ADBE mediates cargo retrieval. We examined the retrieval of different SV cargo molecules during intense stimulation using a series of genetically encoded pH-sensitive reporters in neuronal cultures. The retrieval of only one reporter, VAMP4-pHluorin, was perturbed by inhibiting ADBE. This selective recovery was confirmed by the enrichment of endogenous VAMP4 in purified bulk endosomes formed by ADBE. VAMP4 was also essential for ADBE, with a cytoplasmic di-leucine motif being critical for this role. Therefore, VAMP4 is the first identified ADBE cargo and is essential for this endocytosis mode to proceed.

  20. PINS Measurements of Explosive Simulants for Cargo Screening

    Energy Technology Data Exchange (ETDEWEB)

    2008-06-01

    As part of its efforts to prevent the introduction of explosive threats on commercial flights, the Transportation Security Administration (TSL) is evaluating new explosives detection systems (EDSs) for use in air cargo inspection. The TSL has contracted Battelle to develop a new type of explosives simulant to assist in this development. These are designed to mimic the elemental profile (C, H, N, O, etc.) of explosives as well as their densities. Several “neutron in—gamma out” (n,?) techniques have been considered to quantify the elemental profile in these new simulants and the respective explosives. The method chosen by Battelle is Portable Isotopic Neutron Spectroscopy (PINS), developed by Idaho National Laboratory (INL). Battelle wishes to validate that the simulants behave like the explosive threats with this technology. The results of the validation measurements are presented in this report.

  1. ATHLETE: A Cargo-Handling Vehicle for Solar System Exploration

    Science.gov (United States)

    Wilcox, Brian H.

    2011-01-01

    As part of the NASA Exploration Technology Development Program, the Jet Propulsion Laboratory is developing a vehicle called ATHLETE: the All-Terrain Hex-Limbed Extra-Terrestrial Explorer. Each vehicle is based on six wheels at the ends of six multi-degree-of-freedom limbs. Because each limb has enough degrees of freedom for use as a general-purpose leg, the wheels can be locked and used as feet to walk out of excessively soft or other extreme terrain. Since the vehicle has this alternative mode of traversing through or at least out of extreme terrain, the wheels and wheel actuators can be sized for nominal terrain. There are substantial mass savings in the wheel and wheel actuators associated with designing for nominal instead of extreme terrain. These mass savings are comparable-to or larger-than the extra mass associated with the articulated limbs. As a result, the entire mobility system, including wheels and limbs, can be about 25% lighter than a conventional mobility chassis. A side benefit of this approach is that each limb has sufficient degrees-of-freedom to use as a general-purpose manipulator (hence the name "limb" instead of "leg"). Our prototype ATHLETE vehicles have quick-disconnect tool adapters on the limbs that allow tools to be drawn out of a "tool belt" and maneuvered by the limb. A power-take-off from the wheel actuates the tools, so that they can take advantage of the 1+ horsepower motor in each wheel to enable drilling, gripping or other power-tool functions. Architectural studies have indicated that one useful role for ATHLETE in planetary (moon or Mars) exploration is to "walk" cargo off the payload deck of a lander and transport it across the surface. Recent architectural approaches are focused on the concept that the lander descent stage will use liquid hydrogen as a propellant. This is the highest performance chemical fuel, but it requires very large tanks. A natural geometry for the lander is to have a single throttleable rocket engine on

    In contrast to the well established multiple cellular roles of membrane vesicles in eukaryotic cell biology, outer membrane vesicles (OMV) produced via blebbing of prokaryotic membranes have frequently been regarded as cell debris or microscopy artifacts. Increasingly, however, bacterial membrane vesicles are thought to play a role in microbial virulence, although it remains to be determined whether OMV result from a directed process or from passive disintegration of the outer membrane. Here we establish that the human oral pathogen Porphyromonas gingivalis has a mechanism to selectively sort proteins into OMV, resulting in the preferential packaging of virulence factors into OMV and the exclusion of abundant outer membrane proteins from the protein cargo. Furthermore, we show a critical role for lipopolysaccharide in directing this sorting mechanism. The existence of a process to package specific virulence factors into OMV may significantly alter our current understanding of host-pathogen interactions. PMID:21056982

  11. Advanced analysis of the transverse bulkhead of the a general cargo ship

    Axinte, T.; Nutu, C.; Stanca, C.; Cupsa, O.; Carp, A.

    2016-08-01

    The paper presents the main strength factors stressing the transverse bulkhead of a cargo ship. The transverse bulkhead is one of the main components of the hull for a general cargo vessel. There are presented the role and the importance of the general cargo vessel's type using an original drawing made in NX 8.0 Software from Siemens. Further on, we are presented the importance of the transverse bulkhead of the general cargo ship's hull. Next there are analysed the formability of the transverse bulkhead's material and then we are determining the shear, normal and von Mises stresses in the traverse bulkhead, using the finite element method. Once the stresses are computed, there are also determined the fatigue life, strength safety factor and fatigue safety factor. The analysis of the transverse bulkhead is important for the safety of the general cargo vessel type because if this component of the ship does not resist to the various stresses and high deformations during bad storms on the sea or if the cargo is stored inappropriately, deformations or even breakage of the transverse bulkhead can occur, thus causing damages of the cargo ship, especially under heavy storm.

  12. Mechanisms for exporting large-sized cargoes from the endoplasmic reticulum.

    Science.gov (United States)

    Saito, Kota; Katada, Toshiaki

    2015-10-01

    Cargo proteins exported from the endoplasmic reticulum to the Golgi apparatus are typically transported in coat protein complex II (COPII)-coated vesicles of 60-90 nm diameter. Several cargo molecules including collagens and chylomicrons form structures that are too large to be accommodated by these vesicles, but their secretion still requires COPII proteins. Here, we first review recent progress on large cargo secretions derived especially from animal models and human diseases, which indicate the importance of COPII proteins. We then discuss the recent isolation of specialized factors that modulate the process of COPII-dependent cargo formation to facilitate the exit of large-sized cargoes from the endoplasmic reticulum. Based on these findings, we propose a model that describes the importance of the GTPase cycle for secretion of oversized cargoes. Next, we summarize reports that describe the structures of COPII proteins and how these results provide insight into the mechanism of assembly of the large cargo carriers. Finally, we discuss what issues remain to be solved in the future.

  13. A propagating ATPase gradient drives transport of surface-confined cellular cargo.

    2014-04-01

    The faithful segregation of duplicated genetic material into daughter cells is critical to all organisms. In many bacteria, the segregation of chromosomes involves transport of "centromere-like" loci over the main body of the chromosome, the nucleoid, mediated by a two-protein partition system: a nonspecific DNA-binding ATPase, ParA, and an ATPase stimulator, ParB, which binds to the centromere-like loci. These systems have previously been proposed to function through a filament-based mechanism, analogous to actin- or microtubule-based movement. Here, we reconstituted the F-plasmid partition system using a DNA-carpeted flow cell as an artificial nucleoid surface and magnetic beads coated with plasmid partition complexes as surface-confined cargo. This minimal system recapitulated directed cargo motion driven by a surface ATPase gradient that propagated with the cargo. The dynamics are consistent with a diffusion-ratchet model, whereby the cargo dynamically establishes, and interacts with, a concentration gradient of the ATPase. A chemophoresis force ensues as the cargo perpetually chases the ATPase gradient, allowing the cargo to essentially "surf" the nucleoid on a continuously traveling wave of the ATPase. Demonstration of this non-filament-based motility mechanism in a biological context establishes a distinct class of motor system used for the transport and positioning of large cellular cargo.

  14. Early endosomal escape of a cyclic cell-penetrating peptide allows effective cytosolic cargo delivery.

    Cyclic heptapeptide cyclo(FΦRRRRQ) (cFΦR4, where Φ is l-2-naphthylalanine) was recently found to be efficiently internalized by mammalian cells. In this study, its mechanism of internalization was investigated by perturbing various endocytic events through the introduction of pharmacologic agents and genetic mutations. The results show that cFΦR4 binds directly to membrane phospholipids, is internalized into human cancer cells through endocytosis, and escapes from early endosomes into the cytoplasm. Its cargo capacity was examined with a wide variety of molecules, including small-molecule dyes, linear and cyclic peptides of various charged states, and proteins. Depending on the nature of the cargos, they may be delivered by endocyclic (insertion of cargo into the cFΦR4 ring), exocyclic (attachment of cargo to the Gln side chain), or bicyclic approaches (fusion of cFΦR4 and cyclic cargo rings). The overall delivery efficiency (i.e., delivery of cargo into the cytoplasm and nucleus) of cFΦR4 was 4-12-fold higher than those of nonaarginine, HIV Tat-derived peptide, or penetratin. The higher delivery efficiency, coupled with superior serum stability, minimal toxicity, and synthetic accessibility, renders cFΦR4 a useful transporter for intracellular cargo delivery and a suitable system for investigating the mechanism of endosomal escape.

    The International Space Station will require a continuous supply of replacement parts for ongoing maintenance and repair after the planned retirement of the Space Shuttle in 2010. These parts are existing line-replaceable items collectively called Orbital Replacement Units, and include heavy and oversized items such as Control Moment Gyroscopes and stowed radiator arrays originally intended for delivery aboard the Space Shuttle. Current resupply spacecraft have limited to no capability to deliver these external logistics. In support of NASA's Exploration Systems Architecture Study, a team at Langley Research Center designed an Unpressurized Cargo Delivery Vehicle to deliver bulk cargo to the Space Station. The Unpressurized Cargo Delivery Vehicle was required to deliver at least 13,200 lbs of cargo mounted on at least 18 Flight Releasable Attachment Mechanisms. The Crew Launch Vehicle design recommended in the Exploration Systems Architecture Study would be used to launch one annual resupply flight to the International Space Station. The baseline vehicle design developed here has a cargo capacity of 16,000 lbs mounted on up to 20 Flight Releasable Attachment Mechanisms. Major vehicle components are a 5.5m-diameter cargo module containing two detachable cargo pallets with the payload, a Service Module to provide propulsion and power, and an aerodynamic nose cone. To reduce cost and risk, the Service Module is identical to the one used for the Crew Exploration Vehicle design.

    2004-01-01

    Full Text Available La evidencia empírica mundial muestra un fracaso completo de los programas de promoción del desarrollo, por lo menos en el periodo 1941-2001, lapso en el cual el concepto teórico de desarrollo se convierte en un concepto político. Las diversas formas de intervención y el gasto de cantidades inconmensurables de recursos revelan un mundo patéticamente dividido entre un reducido número de “ganadores” y un enorme conjunto de “perdedores”. El autor plantea que de aquí en adelante habrá que considerar el fomento al desarrollo como un “imperativo categórico” kantiano; que además será preciso colocar en primer plano la dimensión axiológica o valórica del desarrollo, mostrando así su carácter de estado y de proceso intangible, subjetivo, dependiente de la trayectoria y del territorio. Las causas del fracaso del último sexenio se centran, según el autor, en el “peso de la noche cartesiana”, es decir, en el apego irrestricto al paradigma positivista y al método analítico, que, llevado al plano de la acción, se ha traducido en el “incrementalismo disjunto” de Lindblom. El autor sugiere un cambio radical de enfoque, dando paso a un paradigma que combine la complejidad con el constructivismo, que considere el desarrollo como una propiedad emergente de un sistema territorial complejo y que utilice conceptos e instrumentos como la sinapsis neuronal, la sinergia cognitiva y la conversación social como medios para realizar una “ingeniería de las intervenciones territoriales” que genere, efectivamente, el desarrollo. Se plantean complejas cuestiones de reforma en la manera de hacer gobierno.

  17. Redox-regulated cargo binding and release by the peroxisomal targeting signal receptor, Pex5.

    In its role as a mobile receptor for peroxisomal matrix cargo containing a peroxisomal targeting signal called PTS1, the protein Pex5 shuttles between the cytosol and the peroxisome lumen. Pex5 binds PTS1 proteins in the cytosol via its C-terminal tetratricopeptide domains and delivers them to the peroxisome lumen, where the receptor·cargo complex dissociates. The cargo-free receptor is exported to the cytosol for another round of import. How cargo release and receptor recycling are regulated is poorly understood. We found that Pex5 functions as a dimer/oligomer and that its protein interactions with itself (homo-oligomeric) and with Pex8 (hetero-oligomeric) control the binding and release of cargo proteins. These interactions are controlled by a redox-sensitive amino acid, cysteine 10 of Pex5, which is essential for the formation of disulfide bond-linked Pex5 forms, for high affinity cargo binding, and for receptor recycling. Disulfide bond-linked Pex5 showed the highest affinity for PTS1 cargo. Upon reduction of the disulfide bond by dithiothreitol, Pex5 transitioned to a noncovalent dimer, concomitant with the partial release of PTS1 cargo. Additionally, dissipation of the redox balance between the cytosol and the peroxisome lumen caused an import defect. A hetero-oligomeric interaction between the N-terminal domain (amino acids 1-110) of Pex5 and a conserved motif at the C terminus of Pex8 further facilitates cargo release, but only under reducing conditions. This interaction is also important for the release of PTS1 proteins. We suggest a redox-regulated model for Pex5 function during the peroxisomal matrix protein import cycle.

    The current infrastructure for non-intrusive inspection of cargo containers cannot accommodate exploding com-merce volumes and increasingly stringent regulations. There is a pressing need to develop methods to automate parts of the inspection workflow, enabling expert operators to focus on a manageable number of high-risk images. To tackle this challenge, we developed a modular framework for automated X-ray cargo image inspection. Employing state-of-the-art machine learning approaches, including deep learning, we demonstrate high performance for empty container verification and specific threat detection. This work constitutes a significant step towards the partial automation of X-ray cargo image inspection.

  7. Bidirectional transport of motor-driven cargoes in cell: A random walk with memory

    Bhat, Deepak; Gopalakrishnan, Manoj

    2013-02-01

    Motor-driven bidirectional transport inside a cell is an intriguing phenomenon where multiple dyneins and kinesins drag cargoes and deliver them to specific locations. Quite often, both anterograde (plus) and retrograde (minus) directed motors reside simultaneously on the cargo and co-ordinate their activity such that the motion of the cargo looks like spells of plus directed and minus directed segments, with pauses in between. The stochastic tug-of-war model is widely used to analyze this motion, largely studied by computer simulations. Here, we present some analytical results for this model, such as the average durations of plus and minus-run segments and tug-of-war events as well as probabilities of persistence and reversal of directions following a tug-of-war. We show that cargo motion has memory in case of 2 dyneins and 1 kinesin driving together, while it is absent when only a dynein and a kinesin is involved.

    2009-12-28

    We use stochastic computer simulations to study the transport of a spherical cargo particle along a microtubule-like track on a planar substrate by several kinesin-like processive motors. Our newly developed adhesive motor dynamics algorithm combines the numerical integration of a Langevin equation for the motion of a sphere with kinetic rules for the molecular motors. The Langevin part includes diffusive motion, the action of the pulling motors, and hydrodynamic interactions between sphere and wall. The kinetic rules for the motors include binding to and unbinding from the filament as well as active motor steps. We find that the simulated mean transport length increases exponentially with the number of bound motors, in good agreement with earlier results. The number of motors in binding range to the motor track fluctuates in time with a Poissonian distribution, both for springs and cables being used as models for the linker mechanics. Cooperativity in the sense of equal load sharing only occurs for high values for viscosity and attachment time.

  11. Multivalent viral capsids with internal cargo for fibrin imaging.

    Directory of Open Access Journals (Sweden)

    Allie C Obermeyer

    Full Text Available Thrombosis is the cause of many cardiovascular syndromes and is a significant contributor to life-threatening diseases, such as myocardial infarction and stroke. Thrombus targeted imaging agents have the capability to provide molecular information about pathological clots, potentially improving detection, risk stratification, and therapy of thrombosis-related diseases. Nanocarriers are a promising platform for the development of molecular imaging agents as they can be modified to have external targeting ligands and internal functional cargo. In this work, we report the synthesis and use of chemically functionalized bacteriophage MS2 capsids as biomolecule-based nanoparticles for fibrin imaging. The capsids were modified using an oxidative coupling reaction, conjugating ∼90 copies of a fibrin targeting peptide to the exterior of each protein shell. The ability of the multivalent, targeted capsids to bind fibrin was first demonstrated by determining the impact on thrombin-mediated clot formation. The modified capsids out-performed the free peptides and were shown to inhibit clot formation at effective concentrations over ten-fold lower than the monomeric peptide alone. The installation of near-infrared fluorophores on the interior surface of the capsids enabled optical detection of binding to fibrin clots. The targeted capsids bound to fibrin, exhibiting higher signal-to-background than control, non-targeted MS2-based nanoagents. The in vitro assessment of the capsids suggests that fibrin-targeted MS2 capsids could be used as delivery agents to thrombi for diagnostic or therapeutic applications.

    Nowadays archaeological and architectural surveys are based on the acquisition and processing of point clouds, allowing a high metric precision, essential prerequisite for a good documentation. Digital image processing and laser scanner have changed the archaeological survey campaign, from manual and direct survey to a digital one and, actually, multi-image photogrammetry is a good solution for the underwater archaeology. This technical documentation cannot operate alone, but it has to be supported by a topographical survey to georeference all the finds in the same reference system. In the last years the Ca' Foscari and IUAV University of Venice are conducting a research on integrated survey techniques to support underwater metric documentation. The paper will explain all the phases regarding the survey's design, images acquisition, topographic measure and the data processing of two Roman shipwrecks in south Sicily. The cargos of the shipwrecks are composed by huge marble blocks, but they are different for morphological characteristic of the sites, for the depth and for their distribution on the seabed. Photogrammetrical and topographical surveys were organized in two distinct methods, especially for the second one, due to the depth that have allowed an experimentation of GPS RTK's measurements on one shipwreck. Moreover, this kind of three-dimensional documentation is useful for educational and dissemination aspect, for the ease of understanding by wide public.

    Transportation networks play a crucial role in human mobility, the exchange of goods, and the spread of invasive species. With 90% of world trade carried by sea, the global network of merchant ships provides one of the most important modes of transportation. Here we use information about the itineraries of 16,363 cargo ships during the year 2007 to construct a network of links between ports. We show that the network has several features which set it apart from other transportation networks. In particular, most ships can be classified in three categories: bulk dry carriers, container ships and oil tankers. These three categories do not only differ in the ships' physical characteristics, but also in their mobility patterns and networks. Container ships follow regularly repeating paths whereas bulk dry carriers and oil tankers move less predictably between ports. The network of all ship movements possesses a heavy-tailed distribution for the connectivity of ports and for the loads transported on the links with s...

  15. The Lethal Cargo of Myxococcus xanthus Outer Membrane Vesicles

    Directory of Open Access Journals (Sweden)

    James E Berleman

    2014-09-01

    Full Text Available Myxococcus xanthus is a bacterial micro-predator known for hunting other microbes in a wolf pack-like manner. Outer membrane vesicles (OMVs are produced in large quantities by M. xanthus and have a highly organized structure in the extracellular milieu, sometimes occurring in chains that link neighboring cells within a biofilm. OMVs may be a vehicle for mediating wolf pack activity by delivering hydrolytic enzymes and antibiotics aimed at killing prey microbes. Here, both the protein and small molecule cargo of the OMV and membrane fractions of M. xanthus were characterized and compared. Our analysis indicates a number of proteins that are OMV-specific or OMV-enriched, including several with putative hydrolytic function. Secondary metabolite profiling of OMVs identifies 16 molecules, many associated with antibiotic activities. Several hydrolytic enzyme homologs were identified, including MXAN_3564 (mepA, an M36 protease homolog. Genetic disruption of mepA leads to a significant reduction in extracellular protease activity suggesting MepA is the long-predicted (yet to date unknown primary extracellular protease in M. xanthus.

    The design and operation of very large, long-range, subsonic cargo aircraft are considered. A design concept which distributes the payload along the wingspan to counterbalance the aerodynamic loads, with a resultant decrease in the in-flight wing bending moments and shear forces, is described. The decreased loading of the wing structure, coupled with the very thick wing housing the cargo, results in a relatively low overall structural weight in comparison to that of conventional aircraft.

    2015-05-01

    Full Text Available En las últimas décadas el abuso sexual infantil (ASI ha suscitado un gran interés, tanto entre la comunidad científica, como en la sociedad en general, debido a su prevalencia y consecuencias a corto y a largo plazo. Aunque la mayoría de los estudios que han examinado las secuelas del ASI enumeran numerosas dificultades psicológicas, sociales, conductuales y físicas, ciertamente no todas las víctimas de abuso infantil muestran un daño significativo posterior, existiendo una amplia variabilidad en el ajuste de las víctimas. Ante esta diversidad el presente trabajo, tras realizar una revisión de las consecuencias a corto y largo plazo del ASI, pretende discernir cuales son las principales variables que determinan los efectos del abuso sobre la víctimas. Las características del abuso, víctima y agresor, los factores situacionales y, especialmente, las variables cognitivas de la víctima se han demostrado como eficaces para explicar la gravedad de la sintomatología. Concretamente, las investigaciones realizadas en los últimos años han encontrado que la sustitución de estrategias de afrontamiento de evitación por estrategias de aproximación, la eliminación de las atribuciones de autoinculpación e inculpación a la familia y de los sentimientos relacionados con las cuatro dinámicas traumatogénicas y la promoción de un estilo de apego seguro resultarían beneficiosos a la hora de prevenir futuros problemas causados por la experiencia de abuso.

  1. External forces influence the elastic coupling effects during cargo transport by molecular motors.

    Science.gov (United States)

    Berger, Florian; Keller, Corina; Klumpp, Stefan; Lipowsky, Reinhard

    2015-02-01

    Cellular transport is achieved by the cooperative action of molecular motors which are elastically linked to a common cargo. When the motors pull on the cargo at the same time, they experience fluctuating elastic strain forces induced by the stepping of the other motors. These elastic coupling forces can influence the motors' stepping and unbinding behavior and thereby the ability to transport cargos. Based on a generic single motor description, we introduce a framework that explains the response of two identical molecular motors to a constant external force. In particular, we relate the single motor parameters, the coupling strength and the external load force to the dynamics of the motor pair. We derive four distinct transport regimes and determine how the crossover lines between the regimes depend on the load force. Our description of the overall cargo dynamics takes into account relaxational displacements of the cargo caused by the unbinding of one motor. For large forces and weak elastic coupling these back-shifts dominate the displacements. To develop an intuitive understanding about motor cooperativity during cargo transport, we introduce a time scale for load sharing. This time scale allows us to predict how the regulation of single motor parameters influences the cooperativity. As an example, we show that up-regulating the single motor processivity enhances load sharing of the motor pair.

  2. Stall force of a cargo driven by N interacting motor proteins

    Science.gov (United States)

    Bhat, Deepak; Gopalakrishnan, Manoj

    2017-01-01

    We study a generic one-dimensional model for an intracellular cargo driven by N motor proteins against an external applied force. The model includes motor-cargo and motor-motor interactions. The cargo motion is described by an over-damped Langevin equation, while motor dynamics is specified by hopping rates which follow a local detailed balance condition with respect to the change in energy per hopping event. Based on this model, we show that the stall force, the mean external force corresponding to zero mean cargo velocity, is completely independent of the details of the interactions and is, therefore, always equal to the sum of the stall forces of the individual motors. This exact result is arrived on the basis of a simple assumption: the (macroscopic) state of stall of the cargo is analogous to a state of thermodynamic equilibrium, and is characterized by vanishing net probability current between any two microstates, with the latter specified by motor positions relative to the cargo. The corresponding probability distribution of the microstates under stall is also determined. These predictions are in complete agreement with numerical simulations, carried out using specific forms of interaction potentials.

  3. Cargo-towing synthetic nanomachines: towards active transport in microchip devices.

    Wang, Joseph

    2012-05-08

    This review article discusses the use of synthetic catalytic nano motors for cargo manipulations and for developing miniaturized lab-on-chip systems based on autonomous transport. The ability of using chemically-powered artificial nanomotors to capture, transport and release therapeutic payloads or nanostructured biomaterials represents one of the next major prospects for nanomotor development. The increased cargo-towing force of such self-propelled nanomotors, along with their precise motion control within microchannel networks, versatility and facile functionalization, pave the way to new integrated functional lab-on-a-chip powered by active transport and perform a series of tasks. Such use of cargo-towing artificial nanomotors has been inspired by on-chip kinesin molecular shuttles. Functionalized nano/microscale motors can thus be used to pick a selected nano/microscale chemical or biological payload target at the right place, transport and deliver them to a target location in a timely manner. Key challenges for using synthetic nanomachines for driving transport processes along microchannel networks are discussed, including loading and unloading of cargo and precise motion control, along with recent examples of related cargo manipulation processes and guided transport in lab-on-a-chip formats. The exciting research area of cargo-carrying catalytic man-made nanomachines is expected to grow rapidly, to lead to new lab-on-a-chip formats and to provide a wide range of future microchip opportunities.

    2014-09-17

    In clathrin-mediated endocytosis (CME), specificity and selectivity for cargoes are thought to be tightly regulated by cargo-specific adaptors for distinct cellular functions. Here, we show that the actin-binding protein girdin is a regulator of cargo-selective CME. Girdin interacts with dynamin 2, a GTPase that excises endocytic vesicles from the plasma membrane, and functions as its GTPase-activating protein. Interestingly, girdin depletion leads to the defect in clathrin-coated pit formation in the center of cells. Also, we find that girdin differentially interacts with some cargoes, which competitively prevents girdin from interacting with dynamin 2 and confers the cargo selectivity for CME. Therefore, girdin regulates transferrin and E-cadherin endocytosis in the center of cells and their subsequent polarized intracellular localization, but has no effect on integrin and epidermal growth factor receptor endocytosis that occurs at the cell periphery. Our results reveal that girdin regulates selective CME via a mechanism involving dynamin 2, but not by operating as a cargo-specific adaptor.

  5. Irradiation Effects for the Pulsed Fast Neutron Analysis (PFNA) Cargo Interrogation System

    Energy Technology Data Exchange (ETDEWEB)

    Slater, C.O.

    2001-02-02

    At the request of Safety and Ecology Corporation of Tennessee, radiation effects of the proposed Pulsed Fast Neutron Analysis (PFNA) Cargo Interrogation System have been examined. First, fissile cargo were examined to determine if a significant neutron signal would be observable during interrogation. Results indicated that ample multiplication would be seen for near critical bare targets. The water-reflected sphere showed relatively little multiplication. By implication, a fissile target shielded by hydrogenous cargo might not be detectable by neutron interrogation, particularly if reliance is placed on the neutron signal. The cargo may be detectable if use can be made of the ample increase in the photon signal. Second, dose rates were calculated at various locations within and just outside the facility building. These results showed that some dose rates may be higher than the target dose rate of 0.05 mrem/h. However, with limited exposure time, the total dose may be well below the allowed total dose. Lastly, estimates were made of the activation of structures and typical cargo. Most cargo will not be exposed long enough to be activated to levels of concern. On the other hand, portions of the structure may experience buildup of some radionuclides to levels of concern.

Growth projection was estimated by two approaches: one, an optimal systems approach with a more efficient and cost effective system considered as being available in 1990; and the other, an evolutionary approach with an econometric behavior model used to predict long term evolution from the present system. Both approaches predict significant growth in demand for international air freighter services and less growth for U.S. domestic services. Economic analysis of air freighter fleet options indicate very strong market appeal of derivative widebody transports in 1990 with little incentive to develop all new dedicated air freighters utilizing the 1990's technology until sometime beyond the year 2000. Advanced air freighters would be economically attractive for a wide range of payload sizes (to 500 metric tons), however, if a government would share in the RD and T costs by virtue of its needs for a slightly modified version of a civil air freighter design (a.g. military airlifter).

    Large area x-ray detectors based on phosphors coupled to flat panel amorphous silicon diode technology offer significant advances for cargo radiologic imaging. Flat panel area detectors provide large object coverage offering high throughput inspections to meet the high flow rate of container commerce. These detectors provide excellent spatial resolution when needed, and enhanced SNR through low noise electronics. If the resolution is reduced through pixel binning, further advances in SNR are achievable. Extended exposure imaging and frame averaging enables improved x-ray penetration of ultra-thick objects, or "select-your-own" contrast sensitivity at a rate many times faster than LDAs. The areal coverage of flat panel technology provides inherent volumetric imaging with the appropriate scanning methods. Flat panel area detectors have flexible designs in terms of electronic control, scintillator selection, pixel pitch, and frame rates. Their cost is becoming more competitive as production ramps up for the healthcare, nondestructive testing (NDT), and homeland protection industries. Typically used medical and industrial polycrystalline phosphor materials such as Gd2O2S:Tb (GOS) can be applied to megavolt applications if the phosphor layer is sufficiently thick to enhance x-ray absorption, and if a metal radiator is used to augment the quantum detection efficiency and reduce x-ray scatter. Phosphor layers ranging from 0.2-mm to 1-mm can be "sandwiched" between amorphous silicon flat panel diode arrays and metal radiators. Metal plates consisting of W, Pb or Cu, with thicknesses ranging from 0.25-mm to well over 1-mm can be used by covering the entire area of the phosphor plate. In some combinations of high density metal and phosphor layers, the metal plate provides an intensification of 25% in signal due to electron emission from the plate and subsequent excitation within the phosphor material. This further improves the SNR of the system.

    In the present study we investigate the mechanism behind temperature controlled cargo uptake using a truncated octahedral DNA cage scaffold functionalized with one, two, three or four hairpin forming DNA strands inserted in one corner of the structure. This investigation was inspired by our previous demonstration of temperature controlled reversible encapsulation of the cargo enzyme, horseradish peroxidase, in the cage with four hairpin forming strands. However, in this previous study the mechanism of cargo uptake was not directly addressed (Juul, et al., Temperature-Controlled Encapsulation and Release of an Active Enzyme in the Cavity of a Self-Assembled DNA Nanocage, ACS Nano, 2013, 7, 9724-9734). In the present study we use a combination of molecular dynamics simulations and in vitro analyses to unravel the mechanism of cargo uptake in hairpin containing DNA cages. We find that two hairpin forming strands are necessary and sufficient to facilitate efficient cargo uptake, which argues against a full opening-closing of one corner of the structure being responsible for encapsulation. Molecular dynamics simulations were carried out to evaluate the atomistic motions responsible for encapsulation and showed that the two hairpin forming strands facilitated extension of at least one of the face surfaces of the cage scaffold, allowing entrance of the cargo protein into the cavity of the structure. Hence, the presented data demonstrate that cargo uptake does not involve a full opening of the structure. Rather, the uptake mechanism represents a feature of increased flexibility integrated in this nanocage structure upon the addition of at least two hairpin-forming strands.In the present study we investigate the mechanism behind temperature controlled cargo uptake using a truncated octahedral DNA cage scaffold functionalized with one, two, three or four hairpin forming DNA strands inserted in one corner of the structure.

    The endosomal network maintains cellular homeostasis by sorting, recycling and degrading endocytosed cargoes. Retromer organizes the endosomal sorting pathway in conjunction with various sorting nexin (SNX) proteins. The SNX27-retromer complex has recently been identified as a major endosomal hub that regulates endosome-to-plasma membrane recycling by preventing lysosomal entry of cargoes. Here, we show that SNX27 directly interacts with FAM21, which also binds retromer, within the Wiskott-Aldrich syndrome protein and SCAR homologue (WASH) complex. This interaction is required for the precise localization of SNX27 at an endosomal subdomain as well as for recycling of SNX27-retromer cargoes. Furthermore, FAM21 prevents cargo transport to the Golgi apparatus by controlling levels of phosphatidylinositol 4-phosphate, which facilitates cargo dissociation at the Golgi. Together, our results demonstrate that the SNX27-retromer-WASH complex directs cargoes to the plasma membrane by blocking their transport to lysosomes and the Golgi.

    There is currently a great deal of technical and political effort focused on reducing the risk of potential attacks on the United States involving radiological dispersal devices or nuclear weapons. This paper proposes a benchmark problem for gamma-ray and X-ray cargo monitoring with results calculated using MCNP5, v1.51. The primary goal is to provide a benchmark problem that will allow researchers in this area to evaluate Monte Carlo models for both speed and accuracy in both forward and inverse calculational codes and approaches for nuclear security applications. A previous benchmark problem was developed by one of the authors (RPG) for two similar oil well logging problems (Gardner and Verghese, 1991, ). One of those benchmarks has recently been used by at least two researchers in the nuclear threat area to evaluate the speed and accuracy of Monte Carlo codes combined with variance reduction techniques. This apparent need has prompted us to design this benchmark problem specifically for the nuclear threat researcher. This benchmark consists of conceptual design and preliminary calculational results using gamma-ray interactions on a system containing three thicknesses of three different shielding materials. A point source is placed inside the three materials lead, aluminum, and plywood. The first two materials are in right circular cylindrical form while the third is a cube. The entire system rests on a sufficiently thick lead base so as to reduce undesired scattering events. The configuration was arranged in such a manner that as gamma-ray moves from the source outward it first passes through the lead circular cylinder, then the aluminum circular cylinder, and finally the wooden cube before reaching the detector. A 2 in.x4 in.x16 in. box style NaI (Tl) detector was placed 1 m from the point source located in the center with the 4 in.x16 in. side facing the system. The two sources used in the benchmark are {sup 137}Cs and {sup 235}U.

  14. Molecular motors pulling cargos in the viscoelastic cytosol: how power strokes beat subdiffusion.

    The discovery of anomalous diffusion of larger biopolymers and submicron tracers such as endogenous granules, organelles, or virus capsids in living cells, attributed to the viscoelastic nature of the cytoplasm, provokes the question whether this complex environment equally impacts the active intracellular transport of submicron cargos by molecular motors such as kinesins: does the passive anomalous diffusion of free cargo always imply its anomalously slow active transport by motors, the mean transport distance along microtubule growing sublinearly rather than linearly in time? Here we analyze this question within the widely used two-state Brownian ratchet model of kinesin motors based on the continuous-state diffusion along microtubules driven by a flashing binding potential, where the cargo particle is elastically attached to the motor. Depending on the cargo size, the loading force, the amplitude of the binding potential, the turnover frequency of the molecular motor enzyme, and the linker stiffness we demonstrate that the motor transport may turn out either normal or anomalous, as indeed measured experimentally. We show how a highly efficient normal active transport mediated by motors may emerge despite the passive anomalous diffusion of the cargo, and study the intricate effects of the elastic linker. Under different, well specified conditions the microtubule-based motor transport becomes anomalously slow and thus significantly less efficient.

    Synaptic transmission is a fundamental molecular process underlying learning and memory. Successful synaptic transmission involves coupled interaction between electrical signals (action potentials) and chemical signals (neurotransmitters). Defective synaptic transmission has been reported in a variety of neurological disorders such as Autism and Alzheimer's disease. A large variety of macromolecules and organelles are enriched near functional synapses. Although a portion of macromolecules can be produced locally at the synapse, a large number of synaptic components especially the membrane-bound receptors and peptide neurotransmitters require active transport machinery to reach their sites of action. This spatial relocation is mediated by energy-consuming, motor protein-driven cargo trafficking. Properly regulated cargo trafficking is of fundamental importance to neuronal functions, including synaptic transmission. In this review, we discuss the molecular machinery of cargo trafficking with emphasis on new experimental strategies that enable direct modulation of cargo trafficking in live cells. These strategies promise to provide insights into a quantitative understanding of cargo trafficking, which could lead to new intervention strategies for the treatment of neurological diseases.

  16. LUCID: A Quantitative Assay of ESCRT-Mediated Cargo Sorting into Multivesicular Bodies.

    Endosomes are transportation nodes, mediating selective transport of soluble and transmembrane cargos to and from the Golgi apparatus, plasma membrane and lysosomes. As endosomes mature to become multivesicular bodies (MVBs), Endosomal Sorting Complexes Required for Transport (ESCRTs) selectively incorporate transmembrane cargos into vesicles that bud into the endosome lumen. Luminal vesicles and their cargoes are targeted for destruction when MVBs fuse with lysosomes. Common assays of endosomal luminal targeting, including fluorescence microscopy and monitoring of proteolytic cargo maturation, possess significant limitations. We present a quantitative assay system called LUCID (LUCiferase reporter of Intraluminal Deposition) that monitors exposure of chimeric luciferase-cargo reporters to cytosol. Luciferase-chimera signal increases when sorting to the endosome lumen is disrupted, and silencing of signal from the chimera depends upon luminal delivery of the reporter rather than proteolytic degradation. The system presents several advantages, including rapidity, microscale operation and a high degree of reproducibility that enables detection of subtle phenotypic differences. Luciferase reporters provide linear signal over an extremely broad dynamic range, allowing analysis of reporter traffic even at anemic levels of expression. Furthermore, LUCID reports transport kinetics when applied to inducible trafficking reporters.

    Transmembrane receptor clustering is a ubiquitous phenomenon in pro- and eukaryotic cells to physically sense receptor/ligand interactions and subsequently translate an exogenous signal into a cellular response. Despite that receptor cluster formation has been described for a wide variety of receptors, ranging from chemotactic receptors in bacteria to growth factor and neurotransmitter receptors in mammalian cells, a mechanistic understanding of the underlying molecular processes is still puzzling. In an attempt to fill this gap we followed a combined experimental and theoretical approach by dissecting and modulating cargo binding, internalization and cellular response mediated by KDEL receptors (KDELRs) at the mammalian cell surface after interaction with a model cargo/ligand. Using a fluorescent variant of ricin toxin A chain as KDELR-ligand (eGFP-RTA(H/KDEL)), we demonstrate that cargo binding induces dose-dependent receptor cluster formation at and subsequent internalization from the membrane which is associated and counteracted by anterograde and microtubule-assisted receptor transport to preferred docking sites at the plasma membrane. By means of analytical arguments and extensive numerical simulations we show that cargo-synchronized receptor transport from and to the membrane is causative for KDELR/cargo cluster formation at the mammalian cell surface.

  19. The iTRAPs: Guardians of Synaptic Vesicle Cargo Retrieval During Endocytosis.

    The reformation of synaptic vesicles (SVs) during endocytosis is essential for the maintenance of neurotransmission in central nerve terminals. Newly formed SVs must be generated with the correct protein cargo in the correct stoichiometry to be functional for exocytosis. Classical clathrin adaptor protein complexes play a key role in sorting and clustering synaptic vesicle cargo in this regard. However it is becoming increasingly apparent that additional "fail-safe" mechanisms exist to ensure the accurate retrieval of essential cargo molecules. For example, the monomeric adaptor proteins AP180/CALM and stonin-2 are required for the efficient retrieval of synaptobrevin II (sybII) and synaptotagmin-1 respectively. Furthermore, recent studies have revealed that sybII and synaptotagmin-1 interact with other SV cargoes to ensure a high fidelity of retrieval. These cargoes are synaptophysin (for sybII) and SV2A (for synaptotagmin-1). In this review, we summarize current knowledge regarding the retrieval mechanisms for both sybII and synaptotagmin-1 during endocytosis. We also define and set criteria for a new functional group of SV molecules that facilitate the retrieval of their interaction partners. We have termed these molecules intrinsic trafficking partners (iTRAPs) and we discuss how the function of this group impacts on presynaptic performance in both health and disease.
