Online dating sites have transformed the way that people make friends and find partners. Many dating websites have recommendation algorithms that match people with potential partners based on their mutual likes and dislikes, interests, hobbies and so on. That certainly helps to prune the field but the inescapable truth of the online dating game for most people is that you have to kiss a lot of frogs before finding your prince or princess. These guys have built a recommendation engine that not only assesses your tastes but also measures your attractiveness. It then uses this information to recommend potential dates most likely to reply, should you initiate contact. Most web users will be familiar with the recommendation engines on Amazon, Netflix and so on. These work by analysing the set of books you have bought, for example, and then finding other people who have bought a similar set. The problem with this approach is that it takes no account of your attractiveness. If the people you contact never reply, then these recommendations are of little use.
IMO Marine Engine Regulations
MARPOL Annex VI sets limits on NOx and SOx emissions from ship exhausts, and prohibits deliberate emissions of ozone depleting substances from ships of gross tonnage and above engaged in voyages to ports or offshore terminals under the jurisdiction of states that have ratified Annex VI. III standards. Accordingly, Annex VI entered into force on 19 May It applies retroactively to new engines greater than kW installed on vessels constructed on or after January 1, , or which undergo a major conversion after that date.

Over the years, more than 80 research studies have demonstrated that the widespread usage of UpToDate is associated with improved patient care and hospital performance. In , researchers at Harvard University published a compelling study confirming that the use of UpToDate over a three year period was associated with:. Systematic review: the relationship between clinical experience and quality of health care. Ann Intern Med. The study examined the belief that physicians with more years in practice have accumulated knowledge and skills that permit them to deliver higher-quality care.
However, there was an inverse relationship between the number of years that a physician had been in practice and the quality of care that they provided. The authors concluded that:. Clinicians frequently raise questions about patient care in their practice. Although they are effective at finding answers to questions they pursue, roughly half of the questions are never pursued.
This picture has been fairly stable over time despite the broad availability of online evidence resources that can answer these questions.

Staff Writer. More than years later, the primitive forms of turbines driven by the power of steam were explained by Taqi al-Din in as well as Giovanni Branca in These were either small steam jacks or escapement devices. There was a significant industrial challenge that miners faced during the s and this was related to the extraction of water from deep mines. At this time, the true power of steam was showcased as the energy was used to pump up the water from deep within the mines.

Steam engine history dates back to the 1st century AD when the “aeolipile” was the s and this was related to the extraction of water from deep mines.
Although air pollution from ships does not have the direct cause and effect associated with, for example, an oil spill incident, it causes a cumulative effect that contributes to the overall air quality problems encountered by populations in many areas, and also affects the natural environment, such as tough acid rain. Caribbean Sea Emission Control Area. Marine diesel engines installed on a ship constructed on or after 1 January but prior to 1 January are required to comply with “Tier I” emission limits, if an approved method for that engine has been certified by an Administration.
Further, the Tier III requirements do not apply to a marine diesel engine installed on a ship constructed prior to 1 January of less than gross tonnage, of 24 m or over in length, which has been specifically designed and is used solely, for recreational purposes. Revisions to the regulations for ozone-depleting substances, volatile organic compounds, shipboard incineration, reception facilities and fuel oil quality were also made with regulations on fuel oil availability added.
The revised measures are expected to have a significant beneficial impact on the atmospheric environment and on human health, particularly for those people living in port cities and coastal communities.

Analytical Engine , generally considered the first computer , designed and partly built by the English inventor Charles Babbage in the 19th century he worked on it until his death in While working on the Difference Engine , a simpler calculating machine commissioned by the British government, Babbage began to imagine ways to improve it. Chiefly he thought about generalizing its operation so that it could perform other kinds of calculations.

All about differences between BSIV & BSVI engines. Among the regulations set by the governing body, emission-related changes included be dispensed across the country’s petrol pumps from the same date onwards.
This section describes an exemption that allows certificate holders to sell or ship engines that are missing certain emission-related components if those components will be installed by an equipment manufacturer. This section does not apply to equipment subject to equipment -based standards. See the standard-setting part to determine whether and how the provisions of this section apply.
This exemption is temporary as described in paragraph f of this section. We may also require that you apply some or all of the provisions of this section for other components if we determine it is necessary to ensure that shipping the engine without such components will not result in the engine being operated outside of its certified configuration.
In making this determination, we will consider the importance of the component for controlling emissions and the likelihood that equipment manufacturers will have an incentive to disregard your emission-related installation instructions based on any relevant factors, such as the cost of the component and any real or perceived expectation of a negative impact on engine or equipment performance.
For example, you may demonstrate compliance with the requirements of this section by maintaining a database showing how you pair aftertreatment components with the appropriate engines such that the final product is in its certified configuration. For an existing certificate of conformity, amend the application for certification by describing your plans to use the provisions of this section as described in paragraph c 8 of this section. Provide the installation instructions in a timely manner, generally directly after you receive an order for shipping engines or earlier.
If you apply removable labels as described in paragraph c 7 i of this section, include an instruction for the equipment manufacturer to remove the label after installing the appropriate aftertreatment component. This agreement must also obligate the equipment manufacturer to provide the affidavits required under paragraph c 4 of this section.
At a minimum, you must obtain annual affidavits from every equipment manufacturer to which you sell engines under this section. Include engines that you sell to distributors or dealers. The affidavits must list the part numbers of the aftertreatment devices that equipment manufacturers install on each engine they purchase from you under this section and include confirmation that the number of aftertreatment devices received were sufficient for the number of engines involved.
