Programming in Ruby: A critical look at the pros and cons
Nettet15. jun. 2024 · Abstract : ruby has a red spectacular fluorescence under violet or blue-green radiations with a doublet spectrum at 692.80 and 694.30 nm, which appears as a single line. In this post we study the fluorescence of ruby and in particular its lifetime. We show that interesting results can easily be obtained even with our DIY low-cost … Nettet11. nov. 2024 · We also identify the unfortunate limitations of programming in Ruby that seem to restrain the language's adoption status across the development community at large. Quick overview of Ruby While Ruby is certainly its own unique language, it does incorporate a fair amount of influence from Perl in its simplicity, Smalltalk in its … NettetStern and Sognnaes reported that a ruby laser could vaporize enamel and had thermal effects on the dental pulp. In 1970’s, researchers began to find the clinical oral soft tissue uses of medical CO 2 and neodymium-doped:yttrium aluminum garnet (Nd:YAG) lasers. The first laser that had truly both hard and soft tissue application was the CO 2 portsmouth 60+ festival
