In middle resource countries (MRCs), cancer control programs are becoming a priority as the pattern of disease shifts from infectious diseases to non-communicable diseases such as breast cancer, the most common cancer among women in MRCs. The Middle Resource Scenarios Working Group of the BHGI 2010 Global Summit met to identify common issues and obstacles to breast cancer detection, diagnosis and treatment in MRCs. They concluded that breast cancer early detection programs continue to be important, ...

As national health systems seek to apply breast cancer screening recommendations to an entire population of women (within target age ranges for which there is evidence that screening reduces mortality), the volume of screening tests and resulting diagnostic investigations arising from abnormal test results-and the cost associated with them-will grow dramatically. Population-based early detection (screening) programs will need information systems and management tools to help these programs. This report ...

Abstract Spouted bed has been extensively investigated by many authors for years, but the issue of controlling its operation still remains in basic developing stages. The present work consists of the application of an advanced control strategy (QDMC—Quadratic Dynamic Matrix Control) to automate the operation of a large-scale spouted bed dryer. The work on control strategies for spouted bed was motivated by the lack of references on this subject and the encouraging results obtained by Corrêa et al. ( ...

Using a semicylindrical spouted bed to obtain experimental data of cylindrical vessels is an old technique and it has already been widely studied by experimental procedures. In the mathematical modeling of semicylindrical spouted beds, the specularity coefficient is one of the ways of including the effect of shear stress in the solid phase promoted by the flat wall. This parameter can be included in the boundary condition of a semicylindrical spouted bed to represent this friction effect. The main ...

The main aim is to investigate the electric properties in function of the synthesis parameters (milling time and milling power). It was shown that milling parameters strongly influence the electrical properties such as dielectric constant, whose magnitude increases with the milling power. Moreover the relaxation frequency is fully dependent on the milling parameters and it shifts to high ...

This study aims at using a new type of soil bioreactor (13 L bench‐scale and 800 L pilot‐scale) to treat tropical soil contaminated with petroleum. Additionally, it includes the evaluation of the effectiveness of two auxiliary techniques: bulking agent addition (sawdust) and biostimulation using two different ...

Abstract Mechanical properties of thermoplastic polyurethane elastomer (TPE) reinforced with short fibers were studied. Two types of fibers were used as the discontinuous phase: an aromatic polyamide (Twaron, diameter: 12 μm) and carbon fiber (FCI 140/90‐R33—diameter: 8–10 μm). Because of processing limitations, the maximum length of both fibers, after incorporation in the composites, was reduced to 3 mm. The TPE (continuous phase) was a polyol‐polyester type [Elastollan—glass transition of short fiber ...

The introduction of RE cations brought about no significant changes in the structural region of the zeolites. However, in the hydroxyl region, a band ranging from 3530 to 3498 cm−1 may be observed. This band was attributed to OH groups interacting with RE cations and the position thereof is shifted to higher wavenumbers as the ionic radius of the cations ...

In operations using spouted beds, it is of major importance, from an energy consumption point of view, to operate the process as close as possible to the minimum spout flow. At this point, the speed of the gas (for example, warm air in drying operations) is greater than the amount of heat and mass transfer involved, although it only transfers the minimum amount of momentum to maintain the spout. Therefore, by staying close to this minimum flow condition, it is possible to perform a stable operation ...

Bioremediation is an attractive alternative to treat soils contaminated with petroleum hydrocarbons. However, the effectiveness of biodegradation process can be limited by both contaminant characteristics and its bioavailability in soil. This work aims at establishing a preliminary procedure to identify the main factor (hydrocarbon recalcitrance or its bioavailability) that impairs the biodegradation, possibly resulting in low remediation efficiencies.

Abstract Background Excess body weight (EBW), herein defined as body mass index (BMI) ≥25 kg/m 2 , is a well-known modifiable risk factor for cancer and a pivotal vector for growing healthcare costs. We estimated the future (2030) federal direct healthcare costs of cancer in the Brazilian Unified Health System (SUS) attributable to EBW.

Although considerable progress has been made in the development of experimental techniques for investigating velocity distribution inside a fixed bed, these techniques were limited to special cases. Consequently, the velocity distribution is normally measured at downstream of the fixed bed and then this measurement is considered to be representative for the flow inside the bed. To evaluate the representativeness of this technique, this work presents a study of the change in the flow characteristics, ...
