http://www.engineeringnews.co.za/article/emulsion-fuel-has-environmental-benefits-for-boiler-industry-2013-06-07 Environmental technology company Nano Bubble Technologies (NBT) says its emulsion fuels offer the boiler industry environmental and economic benefits. NBT points out that a feature common to emulsion fuels is that they can be used with minimal service and maintenance requirements in boiler plants. The company offers stable and cost-effec-tive fuel emulsions. The production of these emulsions involves the use of chemical additives, a mechanical blending process and technical know-how, ensuring that the emul- sions are stable throughout the working temperature and pressure range. The benefits of using emulsified fuels are derived only if the emulsified fuel remains stable immediately prior to combustion. NBT’s technologies reli- ably produces stable emulsified fuels of consis-tent quality and standard, says the company. “Emulsions are inherently unstable. Over time, they will separate into the stable states of the dispersed and continuous-phase materials. “To maintain the composition of an emulsion, surface-active agents, or ‘surfactants’, are incorporated into the production of an oil-phased emulsion. In an oil-phased emulsion, these surfactant agents encase the droplets of water distributed throughout the continuous oil phase and prevent the water droplets from joining and coalescing,” says NBT depot sales manager Karl Henriksen. NBT’s proprietary technology creates stable mixtures of emulsified fuels, which contain varying percentages of water content. The emulsion technology can be applied to bind various base fuels with water, creating an array of environment-friendly products that reduce both oxides of nitrogen (NOx) and particulate matter (PM) pollution created during the combustion process. “Combustion occurs on the surface of each fuel droplet as the fuel is exposed to oxygen in the air. Larger fuel droplets do not combust completely, causing unburned fuel to escape as particulate matter in exhaust gases. This reduces overall thermal efficiency and increases harmful emissions. “Unlike ordinary fuels, when emulsified fuel droplets are sprayed into the combustion chamber, a secondary atomisation occurs as a result of the violent transformation of the water droplets into steam. This transformation of water into steam shatters the petroleum surrounding the water particle into much smaller fuel droplets,” explains Henriksen. NBT emulsified fuels are a blend of traditional liquid fuels such as diesel, paraffin, heavy-fuel oil or biodiesel and water. The water is present as droplets of about 2 µm, which are distributed throughout the base fuel. The emulsion is known as an oil-phase emulsion. As a result, the finished emulsion has many of the physical characteristics of its base fuel. Emulsion technology better atomises fuel through the vaporisation of water, allowing for a cooler and more complete combustion. In diesel- or biodiesel-based emulsions, extremely small water particles are entrained in the base fuel through a high-shear blending process that employs an additive to bind the water and fuel in a stable emulsion. Emulsions are the only fuel that simultaneously reduces both NOx and PM emissions.

The environment is the complex set of physical, geographic, biological, social, cultural and political conditions that surround an individual or organism and that determine its form and the nature of its survival. The environment influences how people live and how societies. For that reason, people, progress, economic development and environment are closely linked. More Info: http://crowncapitaleco.tumblr.com/ Environmental economics is a sub-field of economics concerned with environmental issues. Environmental economics undertakes theoretical studies of the economics effects on natural or local environmental policies around the world, particular issues include the costs and benefits of alternative environmental policies to deal with air pollution, water quality, toxic substance, solid waste, and global warming (National Bureau of Economic Research). Environmental issues in Pakistan threaten the population’s health and have been disturbing the balance between economic development and environmental protection. The environmental conditions in Pakistan are a matter of great concern. A number of serious environmental problems present in our country, which are of great ecological concern in terms of sustainable economic future. These are water pollution from raw sewage, industrial, limited natural fresh water resources, solid erosion, pesticide misuse, deforestation, desertification and urban pollution. Environment has never been matter of concern for Pakistan and the tendency goes further chronic as all mainstream political parties, bracing for participation in the forthcoming polls, have placed environment issues at the bottom of their draft manifestos. United Nations Framework Convention on Climate Change (UNFCCC), adopted in 1992 and entered into force in 1994 and as a result the adoption of Kyoto Protocol initially in 1997 (which later entered into force on February 16, 2005) has dubbed it necessary for all to have more vibrant climate change policies at political and national level across the world. However in Pakistan, politics has all glamour but blind to environment issues. Indifference on the subject gets more appalling because common people especially civil society have not bothered to bash political leadership for downplaying environment matters in their manifestos. Adding insult to injury, various NGOs engaged in revamping environmental degradation, government departments and independent associations, national and international have also opted out to remain silent over the situation. In terms of words, Pakistan claims to be part of global world but at the time of action, it lacks interest to follow environment protocol, which are accepted and practiced on international front. Even neighbouring country India has better awakening for environmental problems and its political parties are so sensitive on the issue that they have placed climate matters on the top of their manifestos. The Pakistan People’s Party (PPP) was founded in 1967 by late Zulfikar Ali Bhutto but PPP spotted environmental problems during 2002 general elections when late Benazir Bhutto positioned them in party manifesto. The same manifesto was incorporated in 2008 general elections. The manifesto just mentioned them instead putting greater emphasis on environment to ensure water security, green energy, environment-friendly policies and environment curriculum in educational institutions. With similar fashion and mind, PPP’s 13-member manifesto committee is again on the roll to fine tune its 2013 election manifesto highlighting five Es: ‘Employment, education, energy, equality, environment. The Pakistan Muslim League-N headed by two-time Prime Minister Nawaz Sharif has even given a cold shoulder to environment issues in all manifestos. It is not surprising the manifesto does not cater to environment issue specially climate change, pollution of air and marine habitat, water quality, biodiversity, invasive plants and animals, eco-system, unsustainable agriculture, overpopulation and so on and so forth. Pakistan Environment Lawyers’ Association (PELA) President Rafy Aalam criticised political parties for belittling environment issues in their manifestos but courageously confessed “Our like environment associations and NGOs also under-performed as if political parties did nothing and we also stayed out of the focus.” He said, “Had we been in touch with political leadership in making of manifestos giving feedback on environment issues, they might have enlisted environment problems in true letter and spirit and this would have turned as tipping point but we remained dormant.”
So quite simple. I would like a XPS 18 with the new Haswell processors. I also expect Intel Graphics 5,000 or better, and better battery life. It also needs 802.11ac. And I hope you keep all the good configurations (i5 with stand and i7 with stand).Just letting you know, my grandfather wants a i5 XPS 18, but I'm telling him to wait for the Haswell version. :)
Dell should force Microsoft to provide a direct link to a Windows 8 .iso that is available free of charge for everyone. Microsofts current online distribution mechanism for Windows 8 is awful. It firstly requires the user to have a functional previous version of Windows installed. Next it does not allow the user to select 32 bit or 64 bit only downloading setup files which correspond to the bit of the previous version of WIndows. Finally it requires the user to pay for an additional product key. It should be noted that users already have a product key with preinstalled Windows 8 but it is hidden within the system's BIOS. They cannot use this product key to download a Windows 8 .iso. Right now everything is downloadable except for Windows which is required to run everything else Dell have available to download. The .iso would allow users to download everything they require for clean installation of Windows which is necessary to resolve many software issues including complete corruption of the Operating System due to Viruses/Malware and also allow users to get back on their feet after common hardware failure such as the hard drive failing. The Windows 8.iso would also allow users to perform StartUp Repair and to repair installations. Moreover a clean Install of Windows offers vastly superior performance to the Dell factory settings especially after Service Packs are released and is documented in my worldwide adopted Windows Reinstallation Guide: http://philipyip.wordpress.com/dell-community-forums/ In addition there are alot of software issues including out of box experiences, the inability to make recovery media using Dell DataSafe which could all be resolved with a Windows Reinstallation DVD or USB. Note with the Windows Reinstallation USB it should be identical to the Reinstalaltion DVD and not have any bundled drivers or software not present in Microsoft retail Windows DVDs. Otherwise it is as useless as the factory settings. Due to the new product activation in the OEm version fo Windows 8 a generic Windows 8 .iso could be used to Clean Install Windows 8 without the need for phone activation. Users should be able to: Download a Windows 8 .iso from Microsoft. Procure a Reinstallation DVD or USB with the system at the time of purchase. Dell used to be great at user customisation but their software options have become increasing limited. The reinstallation DVD or USB is an example of this. The current method of getting a Reinstallation DVD or USB is waiting for the system to arrive and then having to contact Dell Technical Support. This forces users to use the factory settings until the DVD or USB arrives. In which case there can be alot of software issues, the XPS 8500 had alot of user out of the box bad experiences which could have been easily resolved if they had the Reinstallation DVD or USB. Bare in mind also there is only a limited time the user has to send back the system and if they are diagnosing an out of the box experience time is lost waiting for the Reinstallation DVD to arrive. There should be an online form to procure Reinstallation DVD/USBs from Dell for customers outside the US. The US form is here http://support.dell.com/support/topics/global.aspx/support/dellcare/en/backupcd_form?c=us&cs=19&l=en&s=dhs&redirect=1&DoNotRedirect=y HP for instance have the ability to request media via an online form in the US, Canada, most European countries and elsewhere http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=bph07143 however the HP Recovery Media are equivalent to the Dell DataSafe Media (i.e. factory settings). There has been many a user dissatisfaction for Dell users requesting recovery media in this poll here: http://en.community.dell.com/support-forums/software-os/f/4677/t/19476992.aspx This would improve Dells software services significantly.
If its available on Alinware 14 then why not on A 17? LCD IPS is by no doubt the best display a portable device can ever get (except for maybe an OLED screen .. but no hopes there). It will be amazing to see an IPS display on A 17. And I'm also planning to get an A 17 in the following month and I would definetly pay extra for an IPS Display.
