What do you like best?
This just helps a ton when I need to edit a pdf on my computer. I used to export PDFs as a jpeg and edited the photo and it was super stupid but this is perfect because I never have to try to remember how I edited a PDF the last time I did it.
What do you dislike?
It’s a little clumsy and took a bit for me to figure it out, which means I’m not excellent at explaining how to use it to other people that aren’t technologically inclined, but it still works really well.
What problems are you solving with the product? What benefits have you realized?
I need to edit release forms and vouchers on a daily basis for my models and it’s a breeze with this extension on my laptop.

Kara, The Support Agent
The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.

No single docs (only trial). Unable to split the file.
Despite having a free trial it would be nice to edit and download a single document. This only confuses people and catches you if you forget or are unsuccefull with cancelling within 30 days. I used this site to edit an evacuation plan and it was very easy to do, tools are good. However even with help of customer support still not able to split the plan for seperate sections of a building. I had to rewrite the pdf but I didn't make the plan myself. Overall decent tool for free 30 days but can be better.

Filling out Veteran forms made easy
This PDF filler is so efficient and easy to learn. I help so many veterans with their forms and always had to print them out and fill them out myself. Thank you for helping me help them and others that cannot fill out forms on their own.

pdfFiller is user-friendly and the site is easy to navigate. I love the fact that a function stays the same until you change it, eg. a font size and format. However, I would like the option to use all the Fonts that I have installed on my own computer. When a page is duplicated, I'd love it if the 'changes' made to the original using pdfFiller, could also be duplicated rather than simply a duplication of the original document. I also can't seem to find a way to cut and paste text to apply it in a different area of the document, which means that the process of replicating a change is more time-consuming, but this could be my current unfamiliarity with the software. I was impressed that within a couple of hours of use, I was offered the option to attend a webinar to improve my understanding.

What is the formula for resolution?
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
How do you calculate resolution of a microscope?
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. D= /2 NA. Where is the wavelength of light used to image a specimen. D= 2 /NA2 R= 1.22 /Naomi+Second.
How do you determine the resolution of a microscope?
The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
What is the resolution of a compound microscope?
In a compound microscope, the wavelength of the light waves that illuminate the specimen limits the resolution. The wavelength of visible light ranges from about 400 to 700 nanometers. The best compound microscopes cannot resolve parts of a specimen that are closer together than about 200 nanometers.
How would one improve the resolution of the microscope?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
What is the limit of resolution?
The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. It is the distance between two points in the object that are just resolved in the image.
What factors affect resolution of a microscope?
The primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence of illumination, degree of aberration correction, and other factors such as contrast-enhancing methodology either in the optical system of the microscope or in the
