Exposure of workers to dust and bioaerosol on a poultry farm

Poultry houses are known for generating excessive dust, which originates from bedding materials, fiberglass insulations, feed, dried fecal materials, and feather particles. Dust may contain microorganisms, including endotoxins, fungi, and bacteria, that may affect living things when inhaled. Dust that contains living organisms is referred to as bioaerosol, and its particle size may range from 0.5 to 100 µm. Respirable dust, which has an aerodynamic diameter of less than or equal to 4 µm, can travel to and be deposited in the gas-exchange region of the human respiratory system. This is of particular concern because of the greater health hazard that it poses. The concentrations of respirable dust and bioaerosol measured with samplers attached to the workers (worker-exposure concentrations) were more than 3 (0.82 vs. 0.26 mg/m3) and one-and-a-half times (58.46 vs. 33.79 cfu/m3) higher, respectively, than the concentrations measured with stationary samplers indoors. The respirable dust is still below the permissible exposure limit (5 mg/m3) set by the Occupational Safety and Health Administration, but beyond the limit for animal buildings suggested by other researchers

The beta function of the multichannel Kondo model

The beta function of the multichannel Kondo model is calculated exactly in the limit of large spin N and channel number M=gamma*N, with constant gamma. There are no corrections in any finite order of 1/N. One zero is found at a finite coupling strength, showing directly the Non--Fermi liquid behavior of the model. This renormalization group flow allows to introduce a variational principle for the entropy, to obtain the low temperature thermodynamics. Such in particular the low temperature thermodynamics of the non--crossing approximation to the Kondo model becomes accessible.Comment: 4 page

Exploiting Chordality in Optimization Algorithms for Model Predictive Control

In this chapter we show that chordal structure can be used to devise efficient optimization methods for many common model predictive control problems. The chordal structure is used both for computing search directions efficiently as well as for distributing all the other computations in an interior-point method for solving the problem. The chordal structure can stem both from the sequential nature of the problem as well as from distributed formulations of the problem related to scenario trees or other formulations. The framework enables efficient parallel computations.Comment: arXiv admin note: text overlap with arXiv:1502.0638

Reliability perceptions and water storage expenditures: Evidence from Nicaragua

Storing water at home has become a common practice in many areas with water delivery systems in developing countries. However, little is known about which factors motivate households to expend on water storage devices. Instrumental variable Tobit models are estimated to investigate the relationship between perceptions of water supply reliability and household expenditures on water storage devices in León, Nicaragua. Findings indicate that almost 80% of households use at least one storage device on which they expend an average of 0.87% of their income. Results show that reliability perceptions are the main factor driving household expenditures on storage devices, followed by home ownership and household income. Findings also indicate that reliability perceptions are associated with service performance and assessment of service hours relative to peers

Breast cancer PAM50 signature: Correlation and concordance between RNA-Seq and digital multiplexed gene expression technologies in a triple negative breast cancer series

Background: Full RNA-Seq is a fundamental research tool for whole transcriptome analysis. However, it is too costly and time consuming to be used in routine clinical practice. We evaluated the transcript quantification agreement between RNA-Seq and a digital multiplexed gene expression platform, and the subtype call after running the PAM50 assay in a series of breast cancer patients classified as triple negative by IHC/FISH. The goal of this study is to analyze the concordance between both expression platforms overall, and for calling PAM50 triple negative breast cancer intrinsic subtypes in particular. Results: The analyses were performed in paraffin-embedded tissues from 96 patients recruited in a multicenter, prospective, non-randomized neoadjuvant triple negative breast cancer trial (NCT01560663). Pre-treatment core biopsies were obtained following clinical practice guidelines and conserved as FFPE for further RNA extraction. PAM50 was performed on both digital multiplexed gene expression and RNA-Seq platforms. Subtype assignment was based on the nearest centroid classification following this procedure for both platforms and it was concordant on 96% of the cases (N = 96). In four cases, digital multiplexed gene expression analysis and RNA-Seq were discordant. The Spearman correlation to each of the centroids and the risk of recurrence were above 0.89 in both platforms while the agreement on Proliferation Score reached up to 0.97. In addition, 82% of the individual PAM50 genes showed a correlation coefficient > 0.80. Conclusions: In our analysis, the subtype calling in most of the samples was concordant in both platforms and the potential discordances had reduced clinical implications in terms of prognosis. If speed and cost are the main driving forces then the preferred technique is the digital multiplexed platform, while if whole genome patterns and subtype are the driving forces, then RNA-Seq is the preferred method

Comunicación no verbal en la docencia = Non-verbal communication in teaching

Resumen: La comunicación no verbal ha tenido un gran auge en el último siglo, debido a la importancia demostrada en relativa al mensaje emitido. Este artículo efectúa una aproximación acerca del papel que juega la comunicación no verbal en la credibilidad y congruencia de lo que se dice en clase. Los objetivos del presente trabajo van dirigidos a explicar, explicando las partes de las que consta la comunicación no verbal, cuáles pueden verse obstaculizadas en el discurso y cómo minimizar estas posibles barreras, basándose en una revisión bibliográfica. De esta forma se justifica la importancia de la optimización de los recursos no verbales en el ámbito de la docencia universitaria de titulaciones sanitarias inmersa en el inminente espacio europeo. Palabras clave: Comunicación, Docencia, Lenguaje corporal Abstract: Non-verbal communication has boomed in the last century due to the importance that has shown in the interpretation of the message delivered. This article brings us to the role of nonverbal communication on credibility and consistency of what is said in class. The objectives of this study are point towards to explain, explaining the parts of nonverbal communication, which can be hampered in the speech and how to reduce these potential barriers, based on a literature review. Thereby, It is justified the importance of optimizing nonverbal resources in the scope of health university teaching qualifications immersed in imminent European space.
