    Realizar el análisis histológico de lesiones pódales de pollos comerciales en la planta de sacrificio de Pollo Olympico S.A., Colombia con el fin de discutir aspectos sobre su retención sanitaria en plantas de sacrificio. Materiales y métodos: Se utilizó la población avícola de 10 granjas de la empresa Pollo Olympico S.A evaluando macroscópicamente 129.551 animales y microscópicamente 330 lesiones podales. El análisis histológico evaluó el tipo y la profundidad de las lesiones inflamatorias y la presencia de estructuras micóticas. Resultados: La evaluación macroscópica evidenció lesiones podales en el 64,7% de la población total de aves; la microscópica mostró un predominio de procesos inflamatorios con presentación de heterófilos (73,1%), el 19% fueron infiltrados mixtos y el 7.9% de predominio mononuclear. Las lesiones encontradas mostraron una localización principalmente subcorneal (77.9%) y la ausencia de estructuras micóticas, células gigantes o lesiones vasculares.</jats:p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Las bacterias están clasificadas en el reino Monera, está agrupa a organismos procariotas que producen enfermedades como neumonía, infecciones de vías urinarias, septicemia, infecciones neonatales, infecciones en heridas e infecciones postoperatorias. Así mismo la falta de investigaciones sobre un alimento de gran consumo popular en El Salvador como es la carne de pollo; en la Escuela de Biología, Facultad de Ciencias Naturales y Matemática, Universidad de El Salvador, se realizó la investigación consistió en la muestra de carne de pollo de dos marcas comerciales, adquirida en tres diferentes supermercados de San Salvador; en el laboratorio de Microbiología, utilizando diferentes pruebas bioquímicas para determinar la presencia de enterobacterias y como resultado, se determinó que el 67% de la muestra de pollo para consumo humano analizada estaba contaminada con enterobacterias, el otro 33% corresponde a 15 colonias que no se les realizaron pruebas de identificación

    Pragmatic Case Studies as a Source of Unity in Applied Psychology

    No full text
    To unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

    Determinación de causalidad entre el pollo de calidad b y las lesiones del pollo en la planta de beneficio Avima S.A.

    Incluye tablas, ilustraciones, gráficas y anexos.El presente documento corresponde al informe de pasantía como opción de grado en la empresa de beneficio Avima S.A ubicada en el municipio de Cumaral (Meta), donde se desarrolló pasantía con objetivo que permitiera identificar las diferentes causales presentes en los pollos de engorde tipo B que llegaban a la empresa de sus dos clientes principales (Savicol y Andino). Por lo tanto, se analizó el porcentaje de causalidad de estos pollos según su origen, siendo estos planta y granja (granjas de Cundinamarca y granjas del Meta), con el fin de identificar el porcentaje de causalidad de las lesiones que se presentó con mayor frecuencia y la procedencia de esta. Para cumplir con esta meta, se realizó una caracterización inicial de las condiciones en las que se encontraba el pollo tipo B, con el fin de conocer e identificar las diferentes causales que se encontraban en él. También, se realizó un muestreo diario aleatorio desde el mes de julio hasta el mes de diciembre del año 2021 de cada lote que llegó a la empresa, en dónde se identificó la cantidad de causales procedentes de cada origen de los dos clientes, utilizando como herramienta las planillas de inspección. Al obtenerse los registros mensuales, se tabuló en Excel cada dato y se obtuvo el porcentaje total de cada causal por cada origen.Resumen. -- Justificación. -- 1 Objetivos. -- 1.1 Objetivo General. -- 1.2 Objetivos Específicos. -- 2 Marco Teórico. --.1 Industria Avícola. -- 2.2 Proceso De Beneficio. -- 2.2.1 Colgado. -- 2.2.2 Insensibilización. -- 2.2.3 Degüelle Y Desangre. -- 2.2.4 Escaldado. -- 2.2.5 Pelado. -- 2.2.6 Desprendimiento De Cabeza Y Corte De Patas. -- 2.2.7 Eviscerado. -- 2.2.8 Inspección De La Canal Del Pollo. -- 2.2.9 Prechiller. -- 2.2.10 Chiller. -- 2.2.11 Empaque Y Transporte Del Pollo. -- 2.3 Calidad De La Carne De Pollo. -- 2.4 Hematomas. -- 2.4.1 Calidad De Las Canales. -- 2.5 Contextualización De Empresa. -- 3 Cronograma De Actividades. -- 4 Análisis De Resultados. -- 4.1 Identificación De Causales. -- 4.1.1 Defectos De Granja. -- 4.1.2 Defectos De Planta. -- 4.2 Toma De Datos. -- 4.3 Interpretación De Datos. -- 4.3.1 Causales Según Su Origen. -- 4.3.1.1 Planta. -- 4.3.1.2 Granja. -- 4.3.2 Granjas Muestreadas. -- 4.3.2.1 Granjas Savicol. -- 4.3.2.2 Granjas Andino. -- 5 Conclusiones. -- 6 Recomendaciones. -- 7 Apreciación Persona. -- 8 Referencias. -- Anexos.PregradoIngeniero(a) AgroindustrialIngeniería Agroindustria

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Epilepsy in cerebral glioma: timing of appearance and histological correlations.

    Purpose A prospective study of patients with glioma was carried out. Special attention was paid to the first seizure, to the histology, and to the efficacy and prophylactic role of antiepileptic drugs (AEDs). Prognostic factors were analyzed. Methods Between February 1st 2004 and April 1st 2006 patients who underwent surgical treatment at the Neurosurgery Department of Bolzano for primary or recurrent glioma were prospectively followed until April 1st 2007. Seizures at onset occurring in the absence of interictal epileptiform abnormalities were regarded as remote symptomatic seizures and not treated. Results Sixty-four individuals were registered in the study; epilepsy diagnosis was made in 27 cases and in 24 of these seizures were the onset symptom. The correlation with histological grading showed that seizures were more frequent in low-grade glioma and in secondary glioblastoma. Although epilepsy was less frequent in high-grade glioma, in these patients seizures were more difficult to control. Poor seizure control was associated with motor and sensitive focal seizures and presence of neurological deficit. Patients without epilepsy and not taking AEDs never developed seizures during the follow-up. Discussion Our study clearly shows that epilepsy is more frequent in low-grade gliomas but seizures are more difficult to control in high-grade gliomas. In both cases seizures are a quite exclusive symptom at the onset that never appears during the stable course of the disease. Amongst glioblastoma multiforme (GBM), epilepsy is more frequent in GBM developing through progression from low-grade astrocitoma. Moreover, our study strongly indicates that the prophylactic use of AEDs in glioma is not justified
