 identities for double sums or other methods which can be applied?
Edit
In the mean-time I could prove this identity by reducing it to a corresponding identity for $q-$Narayana polynomials of type A.
But I think there must be also a direct computational proof by comparing coefficients. Could anyone provide such a proof?
Its time again for more updates in the Microsoft Azure certification track If your Microsoft Azure certification path leads you to the Microsoft Certified Azure Solutions Architect Expert role take note. In September 2020 Microsoft retired the AZ-300 and AZ-301 the two exams required for the Microsoft Certified Azure Solutions Architect Expert role. These were 8230.

p Uses flexbox to avoid the need for nested elements, or using overflow hidden to mask super-long absolutely-positioned lines.
p This technique works in all decent browsers, including IE11+. IE10 requires some legacy flexbox syntax and some extra tweaks but also displays as expected.
p IE9 and earlier show partial lines (at the pseudo-element’s min-width), but still looks passable. If content wraps to multiple lines, the after element drops too. Depending on design, I'd use a  #[code.flexbox] Modernizr class to either hide the lines or would revert to an older method where absolute positioning, super-wide fixed-width lines, and overflow hidden are used.
I disagree with saying that shoving as many people into STEM fields is the future. There aren't enough jobs for that, and I doubt enough would be created. Sure, we could use *some* more, but know what else we need? People who are skilled in trades! Plumbers, electricians, carpenters, any skilled trade. All of these are high-demand jobs (there's a reason we're importing foreigners who have experience in skilled trades) that don't involve getting into a mountain of debt and that have salaries that you can easily live off. I'm not saying that STEM degrees are terrible or we should avoid them, I'm a devout lover of physics, but we need to quit the mentality that those are the only things worth doing. Trades are definitely undervalued in high school when students are looking at what they want to do for the rest of their life.#1 How is this possible?
I did plenty of research on internet in last 2 days,and i stumble on one article.
I read that Dr. Mary Higby Schweitzer found soft tissue (blood cells) in 67 million years old T-Rex bone.
So i really don't understand how is that possible if the bone is million years old,and all living tissue is turn in rock.
Sorry for bothering,but i don't know where else to ask.
Some of the "living tissue" wasn't actually tissue at all, but created in reaction to he solvents used I believe. Perhaps some of the tissues were preserved by the sediments where the bones were originally deposited. Then of course you have the thick walls of the bone itself.
I tought those were reliable sites...
Ok - I think I assumed too much and prematurely skipped straight to the end.
To answer your original question: "So i really don't understand how is that possible if the bone is million years old,and all living tissue is turn in rock.!"
Answer: No-one else really understands yet, either.
"I can't make any claims for those structures that appear to be like their modern counterparts until the chemistry reveals whether they are molecular remnants of the original structures, even if altered greatly, or if they are some kind of microbial pseudomorph or even some kind of as yet unknown biogeological process unrelated to structures or molecules produced by the dinosaur itself."
They are reliable sites, what you seem to have missed was the dates of the articles on each. 2006, 2005 and 2005 respectively. This puts all of them as being published before any further research and, the resulting doubts raised, were done on Swhietzers work.
The fossil record is capable of intricate and exquisite preservation of originally soft tissues, sometimesextending to the subcellular level. The number of specimens that may also contain informativebiomolecules is not known, but as technology improves in resolution and sensitivity, sequencesfrom proteins other than—or in addition to—collagen may be recovered from very old fossils,and thus may be used to reconstruct molecular phylogenies. If so, recovered molecules originalto these specimens may shed light on attributes not currently attainable from extinct organisms,such as physiological strategies, the rate and direction of molecular evolution, and the acquisitionof molecular novelties that may have favored radiation into new niches. Because molecular preservationhas been linked to morphological preservation (Colson et al. 1997, Hagelberg et al. 1991),fossils that display any type of soft tissue preservation may be productive for future molecularstudies. Thus, it is important to reserve a portion of these specimens for future studies, when technologicalimprovements may increase our ability to recover and sequence original biomolecules.This may entail new field collection methods, such as using aseptic handling techniques, storingunder inert gas, and analyzing these specimens as soon as possible after recovery from environmentswith which they have come into chemical equilibrium. Details of the physiology, biology,and evolution of long-extinct organismsmay soon be amenable to highly technical analyses, openingthe door to greater understanding of other creatures that have shared this planet with humans.Understanding the adaptations of these organisms at themolecular level to times of global climatechange may provide insight on how to facilitate conservation in the near future, when we face thepossibility of equally rapid and dramatic climate shifts.

Last updated 1st July 2013.It’s not necessarily about the layout, decor style or even trendy accessories that bring your entry to life. The overall personality of a home’s entrance often lies in subtle architectural elements.
Emphasize existing details like your front door and interior stairs. Paint and new hardware transforms your front door from boring to bold. Refinish stair treads and install new rails and balusters. Secure a colorful runner to the treads to dress up an aging staircase.
Update a generic entry by adding wainscoting or a chair rail to enhance dimension. Install crown molding to create visual height. Spruce up unadorned window and door openings with decorative trim. These simple architectural embellishments will give your entry a welcoming look and feel.
The entryway sets the stage for greeting family, friends and guests. Color is an excellent way to define and influence mood. When it comes to choosing wall colors it depends on the size of the space. Consider a bold paint color in a small entry to create a dramatic backdrop.
An expansive two-story foyer may seem daunting when deciding on a wall color. If you go too bright it could become overpowering. In a large open area stick with neutrals, whites or pastel wall colors that are easy on the eyes.
For any size entry a good rule of thumb is to make sure the color flows with the rest of the house. One way to achieve consistency is to use progressive shades of the same color beginning with a saturated hue in the entry. Lighten the pigment as you move into adjoining spaces. This technique not only adds interest to your entry it gives your home a more cohesive and spacious appearance.
A first impression creates a lasting memory so it’s important to choose the right furniture to convey a comfortable and welcoming mood.
In the case of furniture selection size does matter. Pick pieces in relation to your entry’s overall dimensions. Obviously a circular lobby sofa is not the proper scale for a small space. Start by planning your layout by determining a focal point. In a large entry, it typically falls in the center of the space. Fill the void with an oversize round table.
In a small-scale entry or narrow hallway the focal point may be nothing more than a corner or wall. A simple side table, a petite accent chair or a console and mirror work to anchor the area.
Here are tips
