Flow dynamics studies in the NETmix reactor for a large range of flowrate ratio...

The mixing dynamics that occur inside the NETmix reactor have been previously thoroughly studied for equal feed streams distributed through the inlets. To broaden the applicability of this static mixer, this work intends to expand the knowledge of the mixing dynamics mechanisms for cases where dissimilar inlet flowrates are imposed. Computational Fluid Dynamics (CFD) tools were used to simulate flow dynamics ex...

Development of O/W Pickering Emulsions Stabilized with Leek Leaf Trimmings Usin...

Vegetable trimmings can be used to stabilize edible O/W Pickering emulsions. The lignocellulosic biomass (LCB) from the leek trimmings was mechanically treated to produce high-yield lignocellulose micro and nanofibrils (LCF) using a high-pressure homogenizer (HPH). Different O/W phase ratios (20/80, 30/70, and 40/60 wt.%) were studied. The use of the micro/nano cellulosic fibers increased the stabilization of t...

Influence of cold thermal environment on packing workers from the frozen food p...

In the fresh food industry the working activities are conducted in environmental temperatures from 0°C to 10°C, while in the frozen food industry usually are at temperatures below 20°C which influences the variations in core and skin body temperatures and affects the working performance, health and safety of the employees. The aim of this work is to contribute with a study on the influence of cold thermal envir...

Tail prepivoting for the Hill estimator

It is well known that prepivoting reduces level error of confidence sets. We adapt this method to the context of the tail index estimation, introducing a procedure that we call tail prepivoting. We apply this procedure to the Hill estimator and establish its consistency.

Bias-corrected geometric-type estimators of the tail index

The estimation of the tail index is a central topic in extreme value analysis. We consider a geometric-type estimator for the tail index and study its asymptotic properties. We propose here two asymptotic equivalent bias-corrected geometric-type estimators and establish the corresponding asymptotic behaviour. We also apply the suggested estimators to construct asymptotic confidence intervals for this tail param...

STUDY OF THERMAL ENVIRONMENT IN HOSPITAL GYMNASIUMS OF REHABILITATION

In hospital gymnasiums of rehabilitation, thermal environmental conditions represent a transversal risk factor to all occupants (patients, professionals) and with great impact on the sustainability of these institutions. In order to evaluate the thermal comfort conditions, in these places, we analyzed three gymnasiums of rehabilitation of patients. The results revealed situations of discomfort, according to the...
