1. TRAILER HEAT ZONES AND THEIR RELATION TO HEAT STRESS IN PIG TRANSPORT
ABSTRACT This study evaluates the dynamics of heat zones in the load and its relationship with the stress of pigs during transport. Four journeys of 170 km were monitored, recording the physiological variables of 192 animals (48 per journey), namely rectal temperature (RT), body temperature (BT), respiratory rate (RR), blood lactate concentrations and saliva

2. ENVIRONMENTAL THERMAL COMFORT OF A REDUCED MODEL USING CROSS-LAMINATED TIMBER
ABSTRACT The challenges for the use of the cross-laminated timber (CLT) system in the Brazilian agricultural market are significant. This study evaluated the thermal performance of fiber cement tiles associated with a CLT non-conventional structure compared to those of ceramic, fiber cement and aluminum roof tiles based on following thermal comfort indexes (

3. Effect of ultrasound on different quality parameters of functional sirkencubin syrup
Abstract Ultrasound is a process studied intensively for different products due to the increasing interest in non-thermal technologies. Sirkencubin syrup contains honey and vinegar and is a functional beverage maintaining health. The aim of this study was to examine the effects of the ultrasound process (pH, titratable acidity, brix, phenolic compounds, flav

4. STABILIZATION STUDY OF TETRAMERIC Kluyveromyces lactis β-GALACTOSIDASE BY IMMOBILIZATION ON IMMOBEAD: THERMAL, PHYSICO-CHEMICAL, TEXTURAL AND CATALYTIC PROPERTIES
Abstract We investigated the immobilization of a tetrameric Kluyveromyces lactis β-galactosidase (EC: 3.2.1.23) (KL-Gal) on Immobead 150 using different support modification strategies. Immobead support was modified using an acid solution of H2SO4:HNO3 (3:1) (Immobead-Ac) or 5 % (v/v) glutaraldehyde (Immobead-Glu). Its unmodified form (Immobead) was also te

6. Influência dos tratamentos de termorretificação e furfurilação em propriedades tecnológicas de uma conífera
RESUMO O Pinus elliottii Engelm. possui uma vasta possibilidade de aplicações, porém, apresenta características indesejáveis às quais podem ser atenuadas com a adoção dos tratamentos de termorretificação e a furfurilação. Assim, este trabalho analisou a influência que os tratamentos de furfurilição e termorretificação exerceram em propriedad

7. Advanced Oxidation Processes to the Remediation of Liquid Residue from the Thermal Treatment of Oily Sludge
This work reports the remediation of a liquid residue derived from the thermal treatment of petrochemical residues by advanced oxidation processes. Firstly, degradation studies of phenol aqueous solutions by heterogeneous photocatalysis, Fenton, and photo-Fenton were conducted. Fenton processes showed a higher efficiency, mainly in the UVA photo-assisted mod

8. Nonlinear analysis of shape memory alloy beam under the thermal and the mechanical loads
ABSTRACT In this paper, the tension-compression asymmetry of shape memory alloys (SMA), subjected to the thermal and the mechanical loads, is sufficiently explored. Taking a basis of stress-strain relationship and a concern for critical phase transformation, a new simple model of mechanics is established. Through the deflection lines under different load con

10. Physicomechanical and thermal analysis of bulk-fill and conventional composites
Abstract The aim of this study was to evaluate the degree of conversion (DC) and the thermal stability of bulk-fill and conventional composite resins. Eleven composite resin samples were prepared to evaluate the DC, Vickers microhardness (VMH), mass and residue/particle loss, glass transition temperature (Tg), enthalpy, and linear coefficient of thermal expa

11. Modelagem da transferência de calor de ambientes subterrâneos no programa de simulação EnergyPlus
Resumo A temperatura do solo é um dos fatores mais influentes nas avaliações de desempenho térmico de ambientes subterrâneos e quase sempre é desconsiderada. Por isso, é necessário avaliar essa influência devido à interação do solo com a edificação, pois a transferência de calor através de paredes e pisos subterrâneos tem uma extensão signi

12. Mechanical characterization of PM aluminum composites by small punch test
ABSTRACT In this work Small Punch Test (SPT) was applied to study the mechanical behavior of ultrafine-grained Al-Al2O3metal matrix composites (MMCs) fabricated in situ via powder metallurgy route (HITEMAL®). Such MMCs show attractive mechanical properties, enhanced creep performance and increased thermal stability at elevated temperatures, not normally ass
