Total productive maintenance (TPM) as a tool for improving productivity: a case study of application in the bottleneck of an auto-parts machining line

Abstract: This article provides an application of the total productive maintenance (TPM) philosophy as a systematic means for avoiding losses and increasing productivity in an auto-parts machining line. This is achieved by strategically implementing the pillars of TPM on the basis of failure data, then performing a thorough “root cause analysis” thereof (targeted improvement). Preventive maintenance plans and the empowerment of the autonomous maintenance program operator teams become the main pillar in the implementation of this new philosophy as a result. All this is done with the full support of the general management and each area of the organization in order to guarantee the full implementation and sustainability of the program.

Mecanismos de acción de las rizobacterias promotoras del crecimiento vegetal.

Abstract: The population dynamics of the human race has led to the exploitation of natural resources in search of a way to meet the nutritional needs of the billions of people inhabiting the planet. This need has led to the use of high-efficiency materials in agriculture, plant varieties with shorter production cycles that are also resistant to pests and diseases, and chemicals that provide protection against biotic factors (pests and disease), additionally the nutrients required to grow plants. However, the strategies used in modern agriculture have led to negative environmental impacts that we have yet to fully understand. Groundwater contamination, eutrophication, increased greenhouse gases, and the accumulation of toxic substances in the food chain are some of the serious problems that have arisen worldwide due to the indiscriminate use of agrochemicals. As an alternative to the use of these substances, the use of rhizopheric bacteria has been proposed owing to its known action as plant growthpromoting bacteria (PGPB). These bacteria are able to stimulate plant growth directly and indirectly and have several complex mechanisms that interact with each other to establish beneficial relationships, especially with the roots of target plants. The study and understanding of PGPR have been the subjects of great importance in many studies at a global level. This review, therefore, aims to better understand the mechanisms of plant growth-promoting rhizobacteria on plant development and their role in nutrient cycling.

The Fantastic instrument's validity and reliability for measuring Colombian adults' life-style

Abstract: Objetivo El cuestionario «Fantastico» fue creado para ayudar a los profesionales de la salud a medir los estilos de vida de sus pacientes. El objetivo fue evaluar la fiabilidad y validez del cuestionario Fantastico, traducido al espanol en la version de 3 opciones de respuesta, en un grupo de adultos colombianos. Materiales y Metodos Se aplico por entrevista auto diligenciada en 550 personas. Se usaron medidas de tendencia central y dispersion para los dominios y grupos; calculo de consistencia interna y correlacion interescalar. Resultados Se encontro que los 25 items- y los agrupados en los 10 dominios superaron el estandar propuesto de fiabilidad (∞ de Cronbach) mayor a 0,50 y 0,73, respectivamente. Se encontro correlacion interescalar como buenas y aceptables, en las diferentes categorias del cuestionario Fantastico (total vs. dominios), (r= 0,19-0,79 p<0,01). Conclusiones La version 3 del cuestionario Fantastico reune algunos de los criterios de consistencia interna y validez de constructo. Se recomienda utilizar el cuestionario en la atencion primaria en salud y en estudios epidemiologicos.

Bioelectrical Impedance Vector Analysis and Muscular Fitness in Healthy Men

Abstract: Muscle strength can define the general muscular fitness (MF) measurable through hand-grip strength (HG), which is a factor that relates to the health of people of different ages. In this study we evaluated the muscle strength together with a bioimpedance electric analysis in 223 healthy Colombian adult subjects. The bioelectrical impedance vector analysis (BIVA) was conducted to determine the resistance (R), reactance (Xc) and phase angle (PhA). We classified the subjects into three groups (for tertiles), obtaining lower values of R and Xc in subjects with lower HG, plus a high correlation between PhA and HG. An increase in the level of PhA is associated with a high level of MF in a sample of healthy Latin American adult men. The BIVA's parameters and PhA are a potentially effective preventive measure to be integrated into routine screening in the clinical setting.
