La presente investigación se dedicó a evaluar la resistencia a flexión de vigas macizas y vigas laminadas para dos tipos de maderas, en la ciudad de Cajamarca, la cual se origina por la necesidad de conocer la capacidad que presentó estas maderas como lo son el Eucalipto y el Pino, ya que son maderas que se puede conseguir fácilmente en la ciudad de Cajamarca como también son las más económicas del mercado. Los ensayos se realizaron en el Laboratorio de Concreto de la Universidad Privada del Norte, sede Cajamarca, adquiriendo los datos de ensayo para procesar, analizar e interpretar la información, para cada uno de los casos presentados en los ensayos. Para poder obtener la resistencia a la flexión de las vigas de madera, se utilizó como principales elementos la carga máxima que se le aplicó, sus dimensiones y la distancia del apoyo en donde reposó. Esta obtención de infor...

Following the regional protocol designed by the PAHO alcohol and drug program, the relative frequency of injuries in traffi c crashes and injuries, which reached an emergency center with alcohol and / or drugs, Th e Casimiro Ulloa National Hospital (HEJCU) was chosen for the period October 2018 to July 2019. Th e study population was that of the patients who gave us informed consent and the team in charge of sampling, fi lled out the ad-hoc form and collected the results of the breathalyzer and drug test. Th e high frequency of patients who did not give their consent would reveal the high degree of sensitivity towards the detection of alcoholics and drug addicts existing in the city, 15% of alcoholics were detected, 5% of marijuana users, 3% of cocaine and one opiate. An association was detected between alcohol and drug use. Th e drug detection program should incorporate a drug detection...
