BACKGROUND Anatomic dead space (also called airway or tracheal dead space) is the part of the tidal volume that does not participate in gas exchange. Some contemporary ventilation protocols, such as the Acute Respiratory Distress Syndrome Network protocol, call for smaller tidal volumes than were traditionally delivered. With smaller tidal volumes, the percentage of each delivered breath that i...

Background: This study deals with some factors that influence the exposure of whole-body vibration (WBV) dumper operators in surface mines. The also highlights approach to improve multivariate linear analysis outcomes when collinearity exists between certain factor pairs. Material and Methods: A total number 130 readings was taken from two adjacent iron ore frequency-weighted RMS acceleration u...

A transfer or progressive die process consists of multiple stations working simultaneously in each stroke. This paper aims to develop a new methodology that can decompose press tonnage signals to obtain individual station signals without using in-die sensors. In the paper, two different tonnage decomposition tests, as well as the associated data analysis algorithms, are developed. Statistical p...

In the present study, we assessed the agro-industrial performance of 22 sugarcane genotypes adaptable to edaphoclimatic conditions in production microregions in the State of Pernambuco, Brazil, and we recommended the commercial cultivation of select genotypes. The variables analyzed were as follows: sucrose percentage in cane juice, tonnage of saccharose per hectare (TPH), sugarcane tonnage per...

Coal quality-tonnage curves are helpful tools in optimum mine planning and can be estimated using geostatistical simulation methods. In the presence of spatially cross-correlated variables, traditional co-simulation methods are impractical and time consuming. This paper investigates a factor simulation approach based on minimization of spatial cross-correlations with the objective of modeling s...

In the construction of large-tonnage box girder, load girder transport is generally greater than operating in highway industry; therefore, it a crucial task to carry out accurate simulation and optimization on bearing girder. For this purpose, refined modeling method 40 m/1270t studied first paper, followed by detailed stress analysis considering impact coefficient vehicles most unfavorable con...

Di dalam dunia industri banyak peralatan instrument yang dipasang sebagai alat-alat dan peranti (device) dipakai untuk pengukuran pengendalian suatu sistem lebih besar kompleks khususnya di Pembangkit Listrik Tenaga Gas Tanjung Uncang Batam. Untuk memastikan keakuratan alat ukur maupun perangkat berfungsi dengan baik maka diperlukan perawatan atau kalibrasi ulang lakukan secara berkala. Pada um...

Intrapartum death in multiparous gestations in sows (Sus scrofa) is often caused by hypoxia. There is little information in the literature on the assessment of the placenta in relation to intrapartum death in piglets. The aim of this study was to evaluate the impact of the placental area and weight upon piglet birth characteristics and intrapartum death. Litters from 26 Landrace-Yorkshire sows ...
