We use a case study of residential appliance efficiency standards in the Nevada Power Company service territory t o illustrate an integrated method for evaluating the load shape and economic impacts of demand side utility programs. The method consists of four models: the LBL Residential Energy Demand Model, the DOE-2 Building Energy Analysis Model, the LBL Residential Hourly Load and Peak Deman...

Data from freight traffic roadside surveys in Mexican highways are analyzed in order to find consistent patterns or systematic relationships between variables characterizing this traffic. Patterns traced are validated by contrasting against new data sets, allowing so a pattern’s description refinement. In a first stage truck traffic is characterized with respect to vehicle counting size, month ...

BACKGROUND Acute myocardial infarction is defined by a troponin concentration >99th percentile with an acute increase and/or decrease, the magnitude of which has not yet been well defined. To aid the interpretation of changes in cardiac troponin concentration, we sought to establish biological variation and reference change values (RCVs) by applying both the normal and lognormal approaches for ...

This study evaluates the precipitation product of the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG) over the Mexican region during the period between April 2014 and October 2015 using three different time scales for cumulative precipitation (hourly, daily and seasonal). Also, the IMERG data have been analyzed as a function of elevation given the rain gauges ...

We have studied prospectively, in nine children requiring sedation to facilitate mechanical ventilation, the metabolic, biochemical and haemodynamic effects of infusion of propofol. Children were given infusions of propofol 1-4mg kg-1 h-1 and fentanyl 1-5 micrograms kg-1 h-1 for 48 h. Heart rate, arterial pressure, central venous pressure, fluid balance and urine output were recorded hourly and...

Pollen forecasting is of increasing interest as a way to help the general public avoid contact with allergy-inducing pollen. It was recently reported that the dynamics underlying pollen concentration series is very similar to that of low-dimensional deterministic chaos, thus opening up new avenues of development in local pollen forecasting. Our analysis of hourly cedar pollen series for two sea...

Increased night work is an important issue because of its implications on workers' health, safety and performance. This study examined the effects of brief hourly exercise as a countermeasure against the adverse effects of night work, especially for workers requiring sustained attention while working in a prolonged sitting posture. During simulated night work (22:00-08:00), participants were re...
