El presente estudio tiene como finalidad determinar la relación que existe entre el conocimiento tributario y la evasión del impuesto a la renta en los comerciantes de abarrotes del mercado modelo de Chiclayo. Siendo una investigación de tipo descriptivo-correlacional, con diseño no experimental; se tomó una muestra de 92 comerciantes de abarrotes del Mercado Modelo de la ciudad de Chiclayo, a quienes se les aplicó dos encuestas con preguntas dicotómicas que sirvieron para medir el nivel de conocimiento tributario y de la evasión del impuesto a la renta. Cuya validez se determinó con Kurder Richardson (Alfa de Cronbash) dando los resultados de 0.876 y 0.853 respectivamente; lo que le otorga un alto nivel de confiabilidad al estudio. Los resultados muestran que el valor de la significancia es de 0.000 lo que significa que es menor al 5% por lo cual se rechaza la hipótesis nula q...

On the riverbed of Mantaro river, precisely, on the area between La Oroya and 40 km, exist a communication between the cities of lima and Huancayo, where are located: many bridges, the central highway, several hydraulics structures for agricultural use, settlements urban town - La Oroya mining and La Oroya city. All of them exposed to flooding problems caused by maximum flood flows generated in the middle and upper basin of the Mantaro river. In this research we have determined the maximum flood in this area in order to provide security of the entire road infrastructure and existing waterworks. This calculation is very important to prevent the undermining of the design of hydraulic works, infrastructure located at the edge of the river, strengthening of the pillars of bridges, strengthening barrage of intakes, dams and gabions of the same.The results had In this research we have obtained...

This research was made in the hydraulic system of the Hydropower Plant Machupicchu, which has water reserves stored in Sibinacocha lake with a maximum capacity up to 100 million cubic meters. The power plant Mahupicchu was buried in February 1998 by slipping the Ahobamba streams, initiates a first stage of recovery in 2001 achieving sustained generate up to 90 MW and guaranteed by the reserves of the Sibinacocha lake. In the second stage of rehabilitation, initiated in 2009, it aims to increase the generation of 90 MW to 180 MW requiring 61 m3 /s in times of ood and drought, which means requirements higher water volumes stored in Sibinacocha lake. The research simulates the operation of the lake for 47 years (1965 to 2011) considering the requirement of the first and second stage of rehabilitation. The simulation was done with the model Reservoir System Analysis (HEC-3). The simulation r...

In this investigation, the environmental impact was determined by the use of fuels derived from petroleum, coal and natural gas in the planning of the generation of energy of the National Interconnected Electrical System (SEIN) in the period 2016-2019. The amount of C, CH4, N2O, NOx, CO and NMCOV, emitted into the environment by the use of Diesel 2, Residual 500, Residual 6, Coal and Natural Gas fuels has been quantified. These emissions are depended of fuel type, thermoelectric power plant annual energy generation and other factors of emissions due to burning fuels in the Peru`s Electric Sector obtained for Intergovernmental Panel on Climate Change (IPCC) in 1996. The PERSEO model was used to obtain the optimization planning of the SEIN generation expansion in the period 2016-2019 and it is being used by the Supervisory Agency for Energy and Mining Investment (OSINERGMIN).
