On the collisional disalignment of dust grains in illuminated and shaded regions of IC 63
(IOP Publishing, 2021-02)
Interstellar dust grain alignment causes polarization from UV to mm wavelengths, allowing the study of the geometry and strength of the magnetic field. Over the last couple of decades, observations and theory have led to ...
The application of K Phosphites to seed tubers enhanced emergence, early growth and Mycorrhizal Colonization in potato (Solanum tuberosum)
(Scientific Research, 2014-01)
Rapid emergence and a vigorous growth prevent the seed tubers from infections by soil microbes and allow a rapid interception of solar radiation. In this work, the effect of the potassium phosphites (KPhi) applied to seed ...

First study of the radiation-amplitude zero in W gamma production and limits on anomalous WW gamma couplings at root s=1.96 TeV
(2008-06-20)
We present results from a study of pp̄→Wγ+X events utilizing data corresponding to 0.7fb-1 of integrated luminosity at s=1.96TeV collected by the D0 detector at the Fermilab Tevatron Collider. We set limits on anomalous ...

Comparación radiobiológica y dosimétrica con VMAT en cáncer de próstata para esquema convencional vs hipofraccionamiento moderado
(Bogotá - Ciencias - Maestría en Física MédicaDepartamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-01-24)
Radiotherapy treatment plans are normally evaluated from the dose-volume histogram. However, it is advisable to consider other evaluation criteria based on radiobiological indices to compare treatment schemes. In this ...
Estudio de las características dosimétricas de un haz de terapia externa con fotones y nanopartículas de gadolinio y oro
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Física MédicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
La radioterapia es un tratamiento del cáncer, donde se utiliza radiación ionizante con el fin de destruir el tejido tumoral y proteger el tejido sano tanto como sea posible. El propósito de este trabajo fue analizar los ...
Anatomia de espécies brasileiras de Eriocaulaceae: Comanthera e Syngonanthus
(Universidade Estadual Paulista (Unesp), 2016-01-08)
Dentre as Eriocaulaceae (sempre-vivas) brasileiras, alguns representantes de Comanthera e Syngonanthus são os mais comercializados e utilizados na ornamentação e constam da lista brasileira de espécies ameaçadas de extinção. ...
Adaptações morfofisiológicas de araucária ao sombreamento
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2019-05-10)
To verify the morphophysiological adaptations of the arauca ria under shading, two experiments were carried out, one in agroforestry environment with two sizes of seedlings and another under controlled shade. In the agr ...
