El presente trabajo de investigación titulado: “Sistema de gestión de seguridad vial basado en la norma ISO 39001:2013 para la accidentabilidad en la empresa UL&PH Inversiones S.A.C” la cual el objetivo fue Implementar un SGSV para reducir el índice de accidentabilidad en la empresa UL&PH Inversiones S.A.C El problema principal fue determinar ¿Cómo la implementación de un Sistema de gestión de seguridad vial basado en la norma ISO 39001:2013 reduce la accidentabilidad en la empresa UL&PH Inversiones S.A.C? Se planifico una investigación aplicada de estudio descriptivo, siendo de diseño experimental y determinándose en un periodo de 3 meses antes y 3 meses después, analizando nuestras variables. El programa estadístico utilizado para el análisis descriptivo e inferencial fue “SPSS versión 22”, que nos ayudó midiendo nuestros indicadores de la variable independiente, así como el nivel de accidentabilidad en la empresa, luego analizados para validarlos nuestras hipótesis general y especifica. Finalmente se llegó a la conclusión que la implementación de un Sistema de gestión de seguridad vial basado en la norma ISO 39001:2013 redujo el índice de accidentabilidad en la empresa UL&PH Inversiones S.A.

An Online Social Network model through Twitter to build a social perception variable to measure the violence in Mexico

This paper describes the methodology and the model that used in Twitter to create an indicator that allows us to denote a social perception about violence, a topic of high impact in Mexico. We investigated and validated the keywords that Mexicans used related to this topic, in a specific time-lapse defined by the researchers. We implemented two analysis levels, the first one relative to the sum of tweets, and the second one with a rate of total tweets per 100,000 inhabitanThis paper describes the methodology and the model that used in Twitter to create an indicator that allows us to denote a social perception about violence, a topic of high impact in Mexico.

Redshift space power spectrum beyond Einstein-de Sitter kernels

We develop a framework to compute the redshift space power spectrum (PS), with kernels beyond Einstein-de Sitter (EdS), that can be applied to a wide variety of generalized cosmologies. We build upon a formalism that was recently employed for standard cosmology in Chen, Vlah & White (2020), and utilize an expansion of the density-weighted velocity moment generating function that explicitly separates the magnitude of the k-modes and their angle to the line-of-sight direction dependencies. We compute the PS for matter and biased tracers to 1-loop Perturbation Theory (PT) and show that the expansion has a correct infrared and ultraviolet behavior, free of unwanted divergences. We also add Effective Field Theory (EFT) counterterms, necessary to account for small-scale contributions to PT, and employ an IR-resummation prescription to properly model the smearing of the BAO due to large scale bulk flows within Standard-PT. To demonstrate the applicability of our formalism, we apply it on the ΛCDM and the Hu-Sawicki f(R) models, and compare our numerical results against the elephant suite of N-body simulations, finding very good agreement up to k = 0.27 Mpc-1 h at z = 0.5 for the first three non-vanishing Legendre multipoles of the PS. To our knowledge, the model presented in this work is the most accurate theoretical EFT-PT for modified gravity to date, being the only one that accounts for beyond linear local biasing in redshift-space. Hence, we argue our RSD modeling is a promising tool to construct theoretical templates in order to test deviations from ΛCDM using real data obtained from the next stage of cosmological surveys such as DESI and LSST

Quality of the marine and coastal environment in the Ancash Region, 2012

Entre abril y octubre 2012, se evaluó la línea costera y las bahías Coishco, El Ferrol, Samanco, Tortuga, Casma, Huarmey y Caleta Culebras y los ríos Santa, Lacramarca, Casma, Culebras, Huarmey y Samanco. Se localizaron valores termohalinos propios de Aguas Costeras Frías (ACF) con influencias de vertidos antropogénicos y variaciones locales del proceso de evaporación. En abril el oxígeno disuelto presentó valores >5,00 mg/L en toda el área a excepción de la bahía Coishco (3,72 mg/L); en octubre la concentración más alta estuvo en Samanco (7,51 mg/L) y la más baja en Huarmey (2,53 mg/L), el pH estuvo en relación directa con el oxígeno. En abril y octubre los agentes contaminantes de sólidos suspendidos totales presentaron valores >30,00 mg/L en las bahías Coishco, El Ferrol y Tortuga, superando lo permitido por los Estándares Nacionales de Calidad Ambiental para Agua, categoría 4. En abril y octubre la calidad de agua en la cuenca baja de los ríos Santa, Lacramarca, Casma, Culebras y Huarmey respecto a la concentración de la demanda bioquímica de oxígeno estuvo dentro de los Estándares Nacionales de Calidad Ambiental para Agua, categoría 4.ABSTRACT: Between April and October 2012, the coastline and the Coishco, El Ferrol, Samanco, Tortuga, Casma, Huarmey and Culebras Caleta, and rivers Santa, Lacramarca, Casma, Culebras, Huarmey and Samanco was evaluated.

Pastureland Management, and Influence on the Economic Response of Breeding Herds

The influence of the main pastureland components on the economic response of breeding herds at the Rescate de Sanguily Company was studied from January 2012 to December 2014. Six breeding farms from Ricardo Flores Farm were chosen in the municipality of Jimaguayú, province of Camagüey, Cuba. Variables of pastureland, and forage resources in general were used. To determine the main components that led to variability of breeding units, a Principal Component Analysis was performed; components with values above the unit were selected. Stocking rates variables over 0.60 were chosen too. The elements related with pastureland management in breeding units were defined (forage area with native and cultivated grass), which explain the more than 40 % variance in all the units under the study. Forage balance is negative in the units, as a result of poor agro technical management of grasslands; however, the expensesincome ratio is positive (between CUP $2 500 and$17 600), caused by the low feeding costs. Activities and resources linked to pasture and forage agro techniques must be prioritized, along with the completion of forage areas

Mathematical Modelling of Batch Distillation Columns: A Comparative Analysis of Non-Linear and Fuzzy Models

Distillation is the process most commonly used in industry to separate chemical mixtures; its applications range from cosmetic and pharmaceutical to petrochemical industries. The equipment required to perform the distillation process is known as distillation column. Since initial investment and maintenance costs for distillation columns are very high it is necessary to have an appropriate mathematical model that allows improving the comprehension of the column dynamics, especially its thermal behaviour, in order to enhance the control and safety of the process. This chapter presents a general panorama of the mathematical modelling of distillation columns, having as a specific case of study the comparison of a space-state non-linear model and a Takagi-Sugeno fuzzy model for a batch distillation column using a binary mixture (Ethanol-Water)
