Reduction in concentration of chromium (VI) by Lysinibacillus macroides isolated from sediments of the Chapala Lake, Mexico
(2021-04-09)The Chapala Lake is one of the most polluted lakes in Mexico, due to the in fl ow of effl uents from several industrial plants, the lake accumulates pollutants such as chromium(VI) which is considered important for aquatic ... -
Reduction of Stresses and Mass of an Engine Rubber Mount Subject to Mechanical Vibrations
(2021-02-10)A rubber engine mount (EM) is a mechanical coupling between the engine and the chassis, and its main function is to diminish, in the chassis, the amplitude of vibrations caused for the engine operation. Such vibrations ... -
Relationship among Green Production Benefits: A Causal Model
(2020-05-31)Green production processes are becoming increasingly important, as consumers not only demand quality, economical and durable products, but also products that are environmentally friendly. Manufacturers are therefore wondering ... -
Relationship between Burnout and Body Mass Index in Senior and Middle Managers from the Mexican Manufacturing Industry
(2018-03-07)This research relates Burnout Syndrome (BS) with the Body Mass Index (BMI) among middle and senior managers of the Mexican manufacturing industry. Even though BS incidence is high in the Mexican industrial population, few ... -

(2018-03-17)This research relates Burnout Syndrome (BS) with the Body Mass Index (BMI) among middle and senior managers of the Mexican manufacturing industry. Even though BS incidence is high in the Mexican industrial population, ... -
Reliability Analysis Based on a Gamma-Gaussian Deconvolution Degradation Modeling with Measurement Error
(2021-04-30)In most degradation tests, the measuring processes is affected by several conditions that may cause variation in the observed measures. As the measuring process is inherent to the degradation testing, it is important to ... -
Reliability analysis for DC motors under voltage step-stress scenario
(2020-03-10)In reliability analysis, different stress techniques are used to know the lifetime and performance of electrical devices via accelerated life testing. One of these stress technique is the step stress, which combines the ... -
Reliability analysis using exponentiated Weibull distribution and inverse power law
(2019-06-01)Today in reliability analysis, the most used distribution to describe the behavior of devices is theWeibull distribution. Nonetheless, theWeibull distribution does not provide an excellent fit to lifetime datasets that ... -
Reliability by Using Weibull Distribution Based on Vibration Fatigue Damage
(2023-09-14)In this paper, a Weibull probabilistic methodology is proposed with an approach to model vibration fatigue damage accumulation using two parameters: Weibull distribution and a nonlinear fatigue damage accumulation model. ... -
Removal Of Pb And As By Bacteria Isolated From Sediments Of Las Vírgenes Dam And Río Conchos In The State Of Chihuahua, Mexico
(2022-05-31)Lead (Pb) and Arsenic (As) are elements that negatively affect all living organisms if present in the environment. These elements have been reported in the sediments of water supply basins in the State of Chihuahua, Mexico. ... -
Replacement of electric resistive space heating by a geothermal heat pump in a residential application – Environmental amortisation
(2019-11-14)This paper reports the life cycle analysis (LCA) of the replacement of a conventional boiler by a geothermal boiler in a standard, medium sized, single-family dwelling, located in a Mediterranean country such as Spain. The ... -
Replacement of electric resistive space heating by an air-source heat pump in a residential application. Environmental amortization
(2018-05-30)All-electric boilers and air source heat pumps are both powered by electric energy. However, each kWh of heat that is produced implies higher electric consumption in the former. Therefore, as a consequence of financial ... -
Required effort for shaft/ring setting according to roughness due to CNC lathe machining
(2020-12-30)The shaft/hub joints use the difference in diameters to make the assembly, either by pressure or by temperature. In this investigation, a study was made of the effect of roughness in an assembly, represented by the inner ... -
Residual 3D convolutional neural network to enhance sinograms from small-animal positron emission tomography images
(2023-05-05)Positron emission tomography (PET) has been widely used in nuclear medicine to diagnose cancer. PET images suffer from degradation because of the scanner’s physical limitations, the radiotracer’s reduced dose, and the ... -
