Synthetic oil takes the best molecules from natural mineral oil and combines them to form a stronger and more dependable product.
For those who would like to give synthetic oil a try, but might not want to spend an arm and a leg, Pennzoil is a great option.

Motor oil is very important because it keeps a car's engine from overheating and becoming damaged. Motor vehicle manufacturers set performance characteristics and standards for engine oil that petroleum companies are expected to meet.
After interviews with oil experts, mechanics and automakers, one thing is clear: The 3,000-mile oil change is a myth that should be poured out with the dirty oil! Unlike rotating tires or changing oil, there is no standard rule for how often your vehicle needs a coolant flush and fill. Radiators get dirty and antifreeze gradually looses its ability to cool the engine and keep it from freezing in winter.

1906: Availability of panchromatic black and white film and therefore high quality color separation color photography. PAINTING OF THE WEEK - Ruins of the Holyrood Chapel by Moonlight, oil on canvas, 1824, Louis Daguerre.
G+ #Read of the Day: The Daguerreotype - The daguerreotype, an early form of photograph, was invented by Louis Daguerre in the early 19th c.
The first photograph (1826) - Joseph Niepce, a French inventor and pioneer in photography, is generally credited with producing the first photograph. Easy Peasy Fact:Following Niepcea€™s experiments, in 1829 Louis Daguerre stepped up to make some improvements on a novel idea. Formulas have been tested and retested through the years, and there are currently several synthetic motor oils on the market.
According to their website, Amsoil was the first synthetic oil brand to receive a 100 percent rating from the American Petroleum Institute (API). Not only is it affordable, Pennzoil has also proven to be a reliable synthetic oil over the years. Now i would suggest you to get the clutch plates checked and if they need to be changed, get it done. New data shows that changing your oil this often wastes both oil and money, while compounding the environmental impact of illicit waste-oil dumping. Oil has changed quite a bit in the last 30 years.
Radiator size and coolant mix vary from one vehicle to another, and driving habits differ from one person to another. A flush and fill every other year or every 40,000 miles—whichever comes first—is recommended by most vehicle manufacturers.
Owning a dog in an apartment or condo without a backyard requires you as a dog owner to the extra mile for your dog’s exercise and potty needs.
When using pee pads you often have to clean up urine that has spilled off the side of the pee pad and many times dogs simply miss the pee pad. When living in an apartment with a balcony or patio area it is always better to use your indoor grass potty in the outside area. Talbot was active from the mid-1830s, and sits alongside Louis Daguerre as one of the fathers of the medium. Niepcea€™s photograph shows a view from the Window at Le Gras, and it only took eight hours of exposure time!The history of photography has roots in remote antiquity with the discovery of the principle of the camera obscura and the observation that some substances are visibly altered by exposure to light. Again employing the use of solvents and metal plates as a canvas, Daguerre utilized a combination of silver and iodine to make a surface more sensitive to light, thereby taking less time to develop. Choosing the best synthetic oil may lengthen the life of your vehicle's motor and save on gas mileage. While it may not boast the highest API scores, Pennzoil is a mid- to high-range synthetic that is easy to find in stores and has been proven to keep engines clean and performing well in high-heat conditions. In general, synthetic oil can be mixed with conventional oil, but if you are unsure, ask an expert before combining the two.
Among 2013 makes & models, the majority of automobile manufacturers call for oil changes at either 7,500 or 10,000 miles based on normal service schedules.

Those late night and early morning pee runs can be extremely difficult for those of you with demanding work schedules.
When you use the indoor dog grass potty there is no spilling or leaking so you will never have the unfortunate job of wiping up daily urine spills. Porta (1541-1615), a wise Neapolitan, was able to get the image of well-lighted objects through a small hole in one of the faces of a dark chamber; with a convergent lens over the enlarged hole, he noticed that the images got even clearer and sharper. Though he is most famous for his contributions to photography, he was also an accomplished painter and a developer of the diorama theatre.
As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800, when Thomas Wedgwood made the first reliably documented although unsuccessful attempt. Mobil 1 will provide superior protection for your vehicle's motor, as well as excellent fuel efficiency.
Our indoor dog grass potty was created to provide dog owner with a cleaner, easier, and affordable option to their dog potty needs. With real natural grass you never have to deal with any of the clean up associated with the use of paper peed pads and fake synthetic grass. Some companies offer a dog potty solution that is made out of cardboard that is notorious for leaking, beware of these products. Many of our clients in Downtown Los Angeles do not have a patio or balcony and place it indoor. Schulze mixes chalk, nitric acid, and silver in a flask; notices darkening on side of flask exposed to sunlight. A daguerreotype, produced on a silver-plated copper sheet, produces a mirror image photograph of the exposed scene.
Unfortunately, synthetic oil is often more expensive than conventional oil, but in many circumstances (like in high-mileage vehicles, for example), synthetic oil is definitely worth the extra cost. Amsoil runs on the more expensive end of synthetic oil varieties, so be prepared to pay significantly more than you would on conventional oil. Based on a quick web price comparison, a quart of Mobil 1 runs around $8.00, midway between Pennzoil Platinum and Amsoil. Only real natural grass with soil can handle the urine and odors associated with dog urine.
When used outdoor you want to make sure that it gets ample shade so that the real natural grass does not get to dried out by the sun.
The alchemist Fabricio, more or less at the same period of time, observed that silver chloride was darkened by the action of light. Chemistry student Robert Cornelius was so fascinated by the chemical process involved in Daguerrea€™s work that he sought to make some improvements himself. The shortest oil change interval is 5,000 miles in some Hyundai vehicles, Kia models and Toyota vehicles that call for non-synthetic oil. With real grass all you have to do is change out the grass every week or every 2 weeks depending on how much your dog uses it. It was only two hundred years later that the physicist Charles made the first photographic impression, by projecting the outlines of one of his pupils on a white paper sheet impregnated with silver chloride.
It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography.The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by Henry Fox Talbot. And in 1839 Cornelius shot a self-portrait daguerrotype that some historians believe was the first modern photograph of a man ever produced.
With pee pads and synthetic fake grass there is constant daily cleaning and maintenance that must be done.
Also, our cappuccino finish makes the indoor dog grass potty look just like a piece of furniture you would be proud to have in your house.
The photos were turned into lantern slides and projected in registration with the same color filters. Has he actually taken the time to acquire the necessary data to debate my post, or just someone who post great pics???
In 1802, Wedgwood reproduced transparent drawings on a surface sensitized by silver nitrate and exposed to light. Nicephore Niepce (1765-1833) had the idea of using as sensitive material the bitumen, which is altered and made insoluble by light, thus keeping the images obtained unaltered.
Long before the first photographs were made, Chinese philosopher Mo Ti and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BCE. He communicated his experiences to Daguerre (1787-1851) who noticed that a iodide-covered silver plate - thedaguerreotype -, by exposition to iodine fumes, was impressed by the action of light action, and that the almost invisible alteration could be developed with the exposition to mercury fumes. In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experimentsIbn al-Haytham (Alhazen) (965 in Basra a€“ c. It was then fixed with a solution of potassium cyanide, which dissolves the unaltered iodine.The daguerreotype (1839) was the first practical solution for the problem of photography.
In 1841, Claudet discovered quickening substances, thanks to which exposing times were shortened. More or less at the same time period, EnglishWilliam Henry Talbot substituted the steel daguerreotype with paper photographs (named calotype). Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694.

Niepce of Saint-Victor (1805-1870), Nicephorea€™s cousin, invented the photographic glass plate covered with a layer of albumin, sensitized by silver iodide. The novel Giphantie (by the French Tiphaigne de la Roche, 1729a€“74) described what could be interpreted as photography.Around the year 1800, Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance. Maddox and Benett, between 1871 and 1878, discovered the gelatine-bromide plate, as well as how to sensitize it. As with the bitumen process, the result appeared as a positive when it was suitably lit and viewed.
A strong hot solution of common salt served to stabilize or fix the image by removing the remaining silver iodide. On 7 January 1839, this first complete practical photographic process was announced at a meeting of the French Academy of Sciences, and the news quickly spread. At first, all details of the process were withheld and specimens were shown only at Daguerre's studio, under his close supervision, to Academy members and other distinguished guests.
Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image. Unlike a daguerreotype, which could only be copied by rephotographing it with a camera, a calotype negative could be used to make a large number of positive prints by simple contact printing. The calotype had yet another distinction compared to other early photographic processes, in that the finished product lacked fine clarity due to its translucent paper negative. This was seen as a positive attribute for portraits because it softened the appearance of the human face.
Talbot patented this process,[20] which greatly limited its adoption, and spent many years pressing lawsuits against alleged infringers.
He attempted to enforce a very broad interpretation of his patent, earning himself the ill will of photographers who were using the related glass-based processes later introduced by other inventors, but he was eventually defeated.
Nonetheless, Talbot's developed-out silver halide negative process is the basic technology used by chemical film cameras today.
Hippolyte Bayard had also developed a method of photography but delayed announcing it, and so was not recognized as its inventor.In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce. The new formula was sold by the Platinotype Company in London as Sulpho-Pyrogallol Developer.Nineteenth-century experimentation with photographic processes frequently became proprietary. This adaptation influenced the design of cameras for decades and is still found in use today in some professional cameras. Petersburg, Russia studio Levitsky would first propose the idea to artificially light subjects in a studio setting using electric lighting along with daylight. In 1884 George Eastman, of Rochester, New York, developed dry gel on paper, or film, to replace the photographic plate so that a photographer no longer needed to carry boxes of plates and toxic chemicals around. Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie.A practical means of color photography was sought from the very beginning. Results were demonstrated by Edmond Becquerel as early as 1848, but exposures lasting for hours or days were required and the captured colors were so light-sensitive they would only bear very brief inspection in dim light.The first durable color photograph was a set of three black-and-white photographs taken through red, green and blue color filters and shown superimposed by using three projectors with similar filters. It was taken by Thomas Sutton in 1861 for use in a lecture by the Scottish physicist James Clerk Maxwell, who had proposed the method in 1855.[27] The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten. Maxwell's method is now most widely known through the early 20th century work of Sergei Prokudin-Gorskii.
Included were methods for viewing a set of three color-filtered black-and-white photographs in color without having to project them, and for using them to make full-color prints on paper.[28]The first widely used method of color photography was the Autochrome plate, commercially introduced in 1907. If the individual filter elements were small enough, the three primary colors would blend together in the eye and produce the same additive color synthesis as the filtered projection of three separate photographs. Autochrome plates had an integral mosaic filter layer composed of millions of dyed potato starch grains. Reversal processing was used to develop each plate into a transparent positive that could be viewed directly or projected with an ordinary projector. The mosaic filter layer absorbed about 90 percent of the light passing through, so a long exposure was required and a bright projection or viewing light was desirable.
Competing screen plate products soon appeared and film-based versions were eventually made.
A complex processing operation produced complementary cyan, magenta and yellow dye images in those layers, resulting in a subtractive color image. Kirsch at the National Institute of Standards and Technology developed a binary digital version of an existing technology, the wirephoto drum scanner, so that alphanumeric characters, diagrams, photographs and other graphics could be transferred into digital computer memory. The lab was working on the Picturephone and on the development of semiconductor bubble memory. The essence of the design was the ability to transfer charge along the surface of a semiconductor. Michael Tompsett from Bell Labs however, who discovered that the CCD could be used as an imaging sensor.
