Difference between hexavalent chromium and total chromium

Answer»
The partially full d-orbitals in transition metals have energy splittings that HAPPEN to lie in the visible range. Depending on the arrangement of substituents (known as ligands) that attach to them, the electron energies split according to crystal FIELD theory. Similar SPLITTING in the s or p orbitals produce gaps in the ultraviolet, and any visible light goes right through, so we don't see any color. In transition metals, however, visible light excites the ELECTRONS from a lower d orbital to a higher one and only letting some light through.

Difference between cordova and ionic and xamarin

Answer»

What are Hybrid HTML and Cross-Platform Native?

Hybrid HTML frameworks use web technologies JavaScript/HTML/CSS and are interpreted and displayed within the device’s native web view as a standalone application.

Cross-Platform Native frameworks use one programming language across multiple platforms to develop and compile straight into an intermediate language.

Based on these definitions, we can now begin to understand why Ionic, being Hybrid HTML, and Xamarin, being a Cross-Platform Native, perform, look and feel the way they do. Some questions to take into consideration while thinking about choosing between Ionic or Xamarin are:

How much time are you allotting to the development of this mobile application?

Are your developers well-versed in C#/.NET, or JavaScript and Angular?

What is your budget like?

What kind of user experience are you seeking?

The aim of this article is to help you understand key differences between Ionic and Xamarin so that you can MAKE an informed decision between them. Given my experience working with both, I will provide my conclusions and in-depth research. The four factors that we will consider are cost, quality, development and maintainability.

Cost Comparisons of Ionic and Xamarin

As Ionic is open source, its price tag of $0 is quite promising. Likewise, depending on whether or not you’re looking to scale your app in terms of push notifications and deploying to a growing number of devices, you could benefit from the power of Ionic Cloud SERVICES. Ionic Cloud Services offer free push notifications and deployments to devices at a cap of 1,000,000 and 100,000 respectively. Afterwards you will start out with a $20 monthly fee on top of costs for additional push notifications and deployments. For many startups and companies those prices are a steal. Click here for cost details.

Xamarin, now owned by Microsoft, is free with Xamarin Studio (Mac) and Visual Studio Community Edition (Windows) and additional features are available with the paid version of Visual Studio. Depending on what you are trying to ACCOMPLISH, this may or may not be justified. Something to consider will be the learning curve if your team does not have .NET developers or background. The university program for Xamarin education costs $1,995 per developer for the FIRST year and then $1,499 for each year after that. Click here for cost details.
