A participatory ergonomics program in a chemical company

2012

Se describe una intervención de ergonomía participativa iniciada en abril de 2010 en una empresa del sector químico de la Comunidad Valenciana. Se presentó el programa de intervención en la empresa, se acordó el ámbito de la intervención (dos líneas, 24 trabajadores y trabajadoras) y se constituyó un grupo de trabajo (Grupo Ergo, formado por personas responsables, técnicos y delegados de prevención de la empresa) encargado de guiar la intervención. Se recogió mediante cuestionario información acerca de daños y riesgos ergonómicos en los trabajadores y trabajadoras de los puestos seleccionados. Esta información fue analizada por el Grupo Ergo y discutida posteriormente en círculos de prevenc…

Normal and Abnormal Tissue Classification in Positron Emission Tomography Oncological Studies

2018

Positron Emission Tomography (PET) imaging is increasingly used in radiotherapy environment as well as for staging and assessing treatment response. The ability to classify PET tissues, as normal versus abnormal tissues, is crucial for medical analysis and interpretation. For this reason, a system for classifying PET area is implemented and validated. The proposed classification is carried out using k-nearest neighbor (KNN) method with the stratified K-Fold Cross-Validation strategy to enhance the classifier reliability. A dataset of eighty oncological patients are collected for system training and validation. For every patient, lesion (abnormal tissue) and background (normal tissue around …

Brazilian Teachers' Absenteeism: Work Design Predictive Model

2021

Sickness-related absenteeism in teachers represents financial, social, and human costs. This study aimed to analyze the relationship between work characteristics and lengths of absence. The main hypothesis is that different work characteristics are predictors of different lengths of absenteeism. In total, 1,530 teachers participated in the study. The results supported the main hypothesis and suggested that physical demands, task identity, and job complexity are useful to explain absenteeism. It is concluded that analyzing different absenteeism lengths makes it possible to broaden the phenomenon discussion and qualify the relationship between work characteristics and absenteeism. This study …

Synthesis, X-ray Structure Determination, and Comprehensive Photochemical Characterization of (Trifluoromethyl)diazirine-Containing TRPML1 Ligands

2021

Potential (trifluoromethyl)diazirine-based TRPML1 ion channel ligands were designed and synthesized, and their structures were determined by single-crystal X-ray diffraction analysis. Photoactivation studies via 19F NMR spectroscopy and HPLC-MS analysis revealed distinct kinetical characteristics in selected solvents and favorable photochemical properties in an aqueous buffer. These photoactivatable TRPML activators represent useful and valuable tools for TRPML photoaffinity labeling combined with mass spectrometry.

Entryism in the British Labour Party, 1920- 1992

2022

This work aims at studying entryism in the context of the revolutionary socialist left in Britain, from the inception of the Communist Party of Great Britain in 1920 to the departure of Militant, the largest entryist organisation of the Kingdom, from the Labour Party in 1992.Entryism, which is often at the heart of political myths, is a tactic of penetration of a political party by another, aiming at accomplishing objectives, the nature of which can change depending on the type of entry. The intention of this study is to show to what extent there is not one type of entryism but several ones.The adopted methodology is chronological. The first part is dedicated to the relationship between the…

Driving Through Neoliberalism : Finnish Truck Drivers Constructing Respectable Male Worker Subjectivities

2017

This chapter analyses how Finnish male truck drivers (re)produce themselves as respectable male workers in the face of the recent economic, technological and institutional transformations impacting the European haulage sector. The investigation is based on ethnographic data which are produced by riding along on assignments with ten male Finnish truck drivers in the period 2012–2016. The analysis shows how truck drivers’ independence and value in the work process has become challenged and how truckers experience being occupationally stigmatized. The study argues, however, that while economic restructuring undermines some components of traditional forms of working-class masculinity, masculine…

The relation between tumor cell proliferation and vascularization in differentiated and undifferentiated colon carcinomas in the rat.

1982

Tumor cell proliferation and tumor vascularization were investigated in differentiated and undifferentiated colon carcinomas of the rat. The following results were found: 1, in both tumor types, vascularization is developed equally well; 2, both in the differentiated and in the undifferentiated carcinomas, the number of proliferating tumor cells decreases with increasing distance from the capillaries; at a distance of about 80 microns, there is no longer any noteworthy tumor cell proliferation; 3, the differentiated and undifferentiated carcinomas differ both in the level of the mitosis index and 3H-thymidine labeling index as well as in their local proliferation pattern despite equal vascu…
