Rēzus negatīvas grūtnieces antenatālas un agrīnas pēcdzemdību perioda aprūpes analīze Latvijā
2015
Katrā desmitajā rēzus negatīvajā grūtniecībā, māte ir rēzus negatīva, bet auglis rēzus pozitīvs, kas potenciāli predisponē rēzus D izosensibilizācijai. Adekvāta antenatāla un agrīna pēcdzemdību profilakse samazina izosensibilizācijas sastopamību. Pētījumā tika izanalizētas grūtnieču antivielu titri pret D antigēniem un imunizācija antenatālā un agrīnā pēcdzemdību periodā, rēzus negatīvo māšu grupā Latvijā 2012.gadā. Retrospektīvā pētījumā, piecu Latvijas reģionu slimnīcās, tika aplūkotas 75,67% (n=14682) dzemdību nodaļu vēstures no dzemdībam 2012.gadā Latvijā. Tika apkopota informācija par 2052 rēzus negatīvajām grūtniecēm. Reģioni tika salīdzināti savā starpā. Sešas dzemdētāju vēstures ar …
Estudio epidemiológico de salud oral en población escolar del Estado Mexicano de Tabasco
2016
ESTUDIO EPIDEMIOLÓGICO DE SALUD ORAL EN POBLACION ESCOLAR DEL ESTADO MEXICANO DE TABASCO Objetivos: Valorar el estado de salud oral de la población escolar del Estado de Tabasco, México, determinando los índices de caries dental y la prevalencia en escolares con cohortes de 6, 12 y 15 años, mediante el criterio ICDAS. Analizar la relación que existe entre los niveles de caries y el Índice Periodontal Comunitario con los diferentes estratos sociales y determinar la prevalencia de los Defectos de Desarrollo del Esmalte (DDE) y la Fluorosis en dicha población. Comparar la equivalencia entre los criterios diagnósticos de caries de la Organización Mundial de la Salud (OMS) y el Sistema Internaci…
Why Use Interactive Multi-Objective Optimization in Chemical Process Design?
2008
Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…
Consensus nomenclature for CD8(+) T cell phenotypes in cancer
2015
International audience; Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T…
Analysis and evaluation of the inclusive model in infant and primary centre support systems
2016
En esta investigación se analiza el funcionamiento y la organización de los sistemas de apoyo utilizados en centros de Educación Infantil y Primaria de la Comunidad Valenciana. Planteamos hasta qué punto los sistemas de apoyo en estos centros contribuyen a mejorar la organización de un sistema inclusivo que resulte accesible para todos. En el estudio de casos han participado 24 profesionales pertenecientes a cuatro centros que tienen diferentes modalidades de escolarización. Para la recogida de información, se han manejado instrumentos cualitativos como son la entrevista, la observación y el análisis documental. Según los datos obtenidos, los sistemas de apoyo no se ajustan de forma integra…
Maturation of Epidermal Langerhans Cells In Vitro Is Accompanied by Downregulation of 4F2 (CD98) as Determined by Differential Display
1998
Following short-term culture, Langerhans cells mature morphologically and functionally into potent immunostimulatory cells. As regulation of gene expression accompanies this maturation process, it is likely that differentially expressed genes are involved in the maturation events. Using the recently described method of differential display, we generated cDNA expression patterns starting with mRNA of murine epidermal Langerhans cells isolated either directly (fLC) or following 3 d cultivation (cLC). Five hundred putative differentially expressed cDNA fragments were recovered from the gel. For a part of the fragments differential expression was confirmed by dot blot and Southern hybridization…
One-loop corrections to light cone wave functions: the dipole picture DIS cross section
2018
We develop methods needed to perform loop calculations in light cone perturbation theory using a helicity basis, refining the method introduced in our earlier work. In particular this includes implementing a consistent way to contract the four-dimensional tensor structures from the helicity vectors with d-dimensional tensors arising from loop integrals, in a way that can be fully automatized. We demonstrate this explicitly by calculating the one-loop correction to the virtual photon to quark-antiquark dipole light cone wave function. This allows us to calculate the deep inelastic scattering cross section in the dipole formalism to next-to-leading order accuracy. Our results, obtained using …
Understanding McDonald's Among the "World’s Most Ethical Companies"
2008
The animal welfare policies and related public communication initiatives of McDonald’s corporation are examined in the context of the organization being named as one of the world’s most ethical organizations. The result is a framework for understanding how McDonald’s and similar organizations could warrant the status of a most ethical company. Specifically, the narrative strength of the company’s articulation of an animal welfare policy and its ongoing promotion as a legitimizing strategy illustrate how McDonald’s might address the social and ethical issues it encounters through its operations and how its stakeholding publics are likely to respond. By maintaining narrative strength in commu…

Towards controlling PCDD/F production in a multi-fuel fired BFB boiler using two sulfur addition strategies
2014
Abstract PCDD/F abatement strategies – sulfur pellet addition and peat co-combustion – were tested for a BFB boiler facility utilizing SRF-bark-sludge as fuel. In this paper chemical and physical analyses of electrostatic precipitator (ESP) fly ashes were used to explain the differences in the performance of these strategies. These analyses revealed a difference between the coarse and fine fly ashes collected in the ESP. Chemical analysis of the fine fly ashes revealed high concentration of easily volatilized elements while the SEM micrographs showed that fine ash are composed of clusters of spherical particles, thereby leading to a conclusion that fine ashes were originally in a gas phase …
