1. Thermal gradients of container and mean surface temperature of broiler chicks transported on different shipments
ABSTRACT This study aimed to evaluate the thermal gradients between the container environment and the interior of chick boxes and mean surface temperature of broiler chicks during transportation on different shipments. The research was conducted in the state of São Paulo, Brazil, with the accompaniment of nine shipments with different density boxes, using a

2. Prediction of mean surface temperature of broiler chicks and load microclimate during transport
ABSTRACT This study aimed to determine a model to predict mean surface temperature of broiler chicks and live load microclimate conditions during transport by using neural networks. The research was conducted in the state of São Paulo, Brazil, by monitoring nine shipments with different density of boxes using an air-conditioned truck with an average capacit

3. Mechanical and thermal behavior of polyvinyl alcohol reinforced with aligned carbon nanotubes
ABSTRACTIn recent years, due to their high specific mechanical properties, the polymer matrix composites have been widely used. In particular, carbon nanotubes (CNTs) have been used as reinforcement due to its exceptional mechanical and electrical properties. In this work the mechanical behavior of polyvinyl alcohol (PVA) reinforced with different percentage

4. BIOHYDROGEN FROM CHEESE WHEY TREATMENT IN AN AnSBBR: ACHIEVING PROCESS STABILITY
AbstractAn AnSBBR (anaerobic sequencing batch reactor containing biomass immobilized on an inert support) with liquid phase recirculation, containing a 3.5 L working volume, treated 1.5 L of cheese whey wastewater in 3 and 4 h cycles at 30 ºC to produce biohydrogen. From startup the bioreactor presented process instability. To overcome this problem the foll

5. A GRASP ALGORITHM FOR THE CONTAINER LOADING PROBLEM WITH MULTI-DROP CONSTRAINTS
This paper studies a variant of the container loading problem in which to the classical geometric constraints of packing problems we add other conditions appearing in practical problems, the multi-drop constraints. When adding multi-drop constraints, we demand that the relevant boxes must be available, without rearranging others, when each drop-off point is

6. A hybrid methodology to solve the container loading problem with weight distribution and cutting problems
Transport of goods has represented an important role in economic development throughout the history and ship containerization brought great advantages. Its invention in mid-1950s brought down the cost of transport and reduced time for loading and unloading cargo. Consequently, it increased efficiency of port working and reduced handling cargo to hours instea

7. Survival of Ucides cordatus (Decapoda: Ocypodidae) megalopae during transport under different conditions of density and duration
Target areas for Ucides cordatus (Linnaeus, 1763) restocking programs are often located far from the laboratory where larval rearing is developed. During translocation, the larvae are submitted to highly stressful conditions due to handling, packing, and transport activities. The aim of the present study was to assess the mortality rates of U. cordatus megal

8. Metaheurística tabu aplicada ao problema de carregamento de contêiner com caixas idênticas
Intermodal transport, that is, the integration between different transport modes was facilitated by the use of containers. The stowage devices in the breakdown of the cargo is an important logistics activity, since the total volume actually used can affect significantly the cost of transporting the products. This approach addresses the Container Loading Prob

9. Modelos de programação matemática para problemas de carregamento de caixas dentro de contêineres
O objeto de estudo deste trabalho é um caso particular dos problemas de corte e empacotamento, conhecido como problemas de carregamento de contêineres. Estes problemas consistem em arranjar caixas retangulares ortogonalmente dentro de contêineres (ou caminhões, vagões ferroviários e paletes), de maneira a otimizar uma função objetivo, por exemplo, ma

10. Integração dos problemas de carregamento e roteamento de veículos com janela de tempo e frota heterogênea. / Integration of loading and vehicle routing problems with time windows and heterogeneous fleet.
Este trabalho aborda um problema ainda não explorado na literatura denominado 3L-FSMVRPTW (three-dimensional loading fleet sizing and mix vehicle routing problem with time windows), que compreende resolver simultaneamente o roteamento e carregamento tridimensional de veículos considerando frota heterogênea e janela de tempo. Foi desenvolvido um algoritmo

11. A multi-start random constructive heuristic for the container loading problem
Neste trabalho abordamos o problema de carregamento de contêiner que trata da seleção de um subconjunto de caixas, cada caixa com um dado volume, de forma a maximizar o volume ocupado de um único contêiner sujeito a restrições de orientação e estabilidade. Propomos uma heurística construtiva aleatória com múltiplos inícios que utiliza um arranjo

12. Three-dimensional cutting and packing problems and integration with vehicle routing / Problemas de corte e empacotamento tridimensional e integração com roteamento de veiculos
The wide-scale adoption of the containers made the development of the multimodal transport possible. Nowadays, shipment of boxes in containers is an important activity for companies that have in the load transport a logistic factor of high cost. This work presents the development and the application of metaheuristics with adaptive memory in order to solve th
