Drastically reducing fuel consumption and emissions of commercial aircraft

The diesel particulate filter is designed to trap and store Particulate Material soot that is produced by the diesel engine during normal driving. The DPF allows exhaust gases with Particulate Material to enter the DPF and the soot is trapped inside the filter, allowing cleaner exhaust gases to exit into the atmosphere which reduces exhaust emissions. Vehicle manufacturers are required to reduce diesel engine emissions in accordance with the Euro Emission standards. In order to achieve this reduced level of PM soot , diesel particulate filters are now fitted to diesel engine vehicles. The diesel particulate filter WILL, if left, block up. In order to operate fully, the DPF needs to regenerate. Regeneration is a process to clear the soot that has been collected inside the DPF. Failure to regenerate will result in the soot building up inside the DPF, which leads to a lack of power problems due to the high back pressure in the exhaust. The vehicle will then illuminate its engine management and emission warning lights to warn the driver of a problem. Connecting diagnostic equipment to the vehicle will retrieve diagnostic trouble codes, which are used to locate the area of the engine requiring investigation.

Aetna considers positron emission tomography PET medically necessary for the following cardiac indications:. PET scans using rubidium Rb or N ammonia done at rest or with pharmacological stress are considered medically necessary for non-invasive imaging of the perfusion of the heart for the diagnosis and management of members with known or suspected coronary artery disease, provided such scans meet either one of the two following criteria:.

In these cases, the PET scan must have been considered necessary in order to determine what medical or surgical intervention is required to treat the member. Fluorodeoxy-D-glucose FDG -PET scans are considered medically necessary for the determination of myocardial viability prior to re-vascularization, either as a primary or initial diagnostic study or following an inconclusive SPECT.

But what exactly goes into building a new engine? And how do you ensure it meets customer requirements? This website uses cookies. By continuing, we assume that you accept such use. Developing a new genset engine is both a big investment and challenge. At Volvo Penta , we focus on what brings value to our customers and put their needs at the heart of our design process.

Based on their input, our top priorities were high power density, a compact size, low fuel consumption, low noise levels, ease of installation and reliability. They told us that they would mainly use the new engine as a reliable source of back-up power, as well as cost-effective primary power generation in areas where energy is scarce. And there was a demand for the engine to be used in both mobile and stationary power generation applications.

This gave us some very clear goals and made sure everyone involved in the project was pulling in the same direction and knew exactly what we needed to accomplish. The power of the Volvo Group As Volvo Penta is part of the Volvo Group , we are in the privileged position to have the strength of the Group behind us and all the benefits this brings for sharing technologies.

Emission rates ranged from 0. A dependence of the emission rates on temperature as well as on light intensity was observed. Our results suggest that an emission algorithm for all compounds emitted from sunflower and beech has to consider temperature and light intensity simultaneously. The observations strongly indicate that the emissions of VOCs from sunflower and beech are in part closely coupled to the rate of biosynthesis and in part originate from diffusion out of pools.

The emission rates can be described by an algorithm that combines the model given by Tingey and coworkers with the algorithm given by Guenther and coworkers after slight modification. This is a preview of subscription content, log in to check access.

In recent years, organometal halide perovskite materials have attracted significant research interest in the field of optoelectronics. Here, we introduce a simple and low-temperature route for the formation of self-assembled perovskite nanocrystals in a solid organic matrix. We demonstrate that the size and photoluminescence peak of the perovskite nanocrystals can be tuned by varying the concentration of perovskite in the matrix material.

The material also exhibits efficient lasing under optical pumping. The majority of investigations to date concern the bulk properties of the Pe, despite the fact that the formation of nanometer-sized structures was noted in the pioneering work by Kojima et al. So far, however, there is no literature available concerning the ability to tune the size of the Pe nanocrystals and their size-dependent properties.

All of these applications are hereby incorporated by reference in their entireties. The invention relates to an improved two component adhesive system, a kit comprising said two adhesive components, its use and a method for production of interior wood products, in particular form-pressed products, parquet floor elements and furniture boards with very low formaldehyde emission and to the interior wood products obtainable having improved properties.

The gluing process is performed in a mould to give the final product the desired shape. The most commonly used adhesive for this application is urea formaldehyde type adhesive UF as it gives excellent performance as well as being inexpensive. UF adhesives are, however, not the only adhesive type used for form pressing.

PVAc adhesives can only be used for very simple construction without much tension due to the thermoplastic nature of PVAc adhesives. For more challenging constructions, EPI adhesives may be used. The use of EPI adhesives offers challenges such as handling of the isocyanate hardener, limited pot life, limited assembly time, relatively long pressing times, potential of creep of the glue line due to the thermoplastic nature of the adhesive and high cost.

UF adhesives are based on formaldehyde and will, depending on the adhesive formulation, give more or less emission of formaldehyde from the final product. With the increased focus on formaldehyde emission and increasingly stricter restrictions of the emissions this is posing a greater and greater problem. This has been accentuated by some customer’s decision of using formaldehyde free adhesives in all products where this is possible as well as the suggestion of very strict Californian regulations regarding formaldehyde emission from glued products.

Over the years the UF technology has been improved to minimize the amount of formaldehyde that is emitted from the glued products. There is however a limitation to how much can be done with a UF system as the bond quality is getting reduced as the emission is lowered. This is a very big problem for form bent products where the final product usually contains a high number of glue lines from 2 to 49 and a large amount of glue.
