RapidTyping is a convenient and easy-to-use keyboard trainer that will help you improve your typing speed and reduce typos. With its lessons organized for various student level, RapidTyping will teach you touch typing or enhance existing skills.
As an educational material, RapidTyping combines animated backgrounds and a brightly colored interface to teach users touch typing or the technique of typing words without the need to look at the keyboard every so often. This is an important skill for writers, programmers, encoders, and the like.
Advance your typing speed and accuracy with the newest typing tutor! With Rapid Typing Tutor you will learn using your keyboard more efficiently in just a few easy lessons for absolutely free. Kids can learn by playing a typing game, while adults can take pre-configured courses or create their own training lessons. Rapid Typing Tutor is perfect for adults and kids, students and teachers, and provides comprehensive reporting and progress tracking for every student. Powerful statistics include 15 different parameters, including words-per-minute, characters-per-minute and accuracy reports.
The innovative typing tutor has a cheerful and intuitive user interface full of colors to make learning to type fun. The typing tutor features a variety of visual cues to help adults and kids master the computer keyboard, and provides full course statistics in tables and charts. Supporting multiple users makes Rapid Typing Tutor usable at schools, colleges and universities.
Secretaries, teachers and writers will find the ability of Rapid Typing Tutor to create their own courses custom-tailored to each student truly indispensible. Custom courses make it possible creating your own typing tutor meeting your own requirements. Whether you need to master a specific key, set of keys or a keyboard layout that you need to master, a custom-built typing tutor is your best solution.
The free typing tutor includes a full virtual keyboard with both hands moving over it to display the proper typing position for each hand and finger. Highlighted zones for each finger make placing your fingers correctly a second nature in no time.
For non-standard layout users, Rapid Typing Tutor automatically creates a new virtual keyboard based on the layout. You can take typing lessons for multiple keyboard layouts by quickly switching between them.
Randomly amplified polymorphic DNA (RAPD) has been used for rapid typing of Lactobacillus plantarum strains. RAPD was used with either purified chromosomal DNA serving as template in the polymerase chain reaction, or with crude cell extracts, and using a 9-mer primer with 80% G+C content. Amplified DNA was visualized by ethidium bromide staining after separation on agarose gels. Patterns from 20 Lact. plantarum strains and two Lact. pentosus strains were analysed using the Pearson products moment correlation coefficient (r) and the unweighted pair group method with arithmetic averages (UPGMA). With some exceptions, the two sources of template DNA gave the same clusters and subclusters of strains at the similarity level of 50%. About 50% of the strains could be individually separated from all the other tested strains. The buffer brand, the amount of primer and crude cell extract used in the PCR-step were crucial for the final pattern.
The opportunistic human pathogen Propionibacterium acnes is composed of a number of distinct phylogroups, designated types IA1, IA2, IB, IC, II, and III, which vary in their production of putative virulence factors, their inflammatory potential, and their biochemical, aggregative, and morphological characteristics. Although multilocus sequence typing (MLST) currently represents the gold standard for unambiguous phylogroup classification and individual strain identification, it is a labor-intensive and time-consuming technique. As a consequence, we developed a multiplex touchdown PCR assay that in a single reaction can confirm the species identity and phylogeny of an isolate based on its pattern of reaction with six primer sets that target the 16S rRNA gene (all isolates), ATPase (types IA1, IA2, and IC), sodA (types IA2 and IB), atpD (type II), and recA (type III) housekeeping genes, as well as a Fic family toxin gene (type IC). When applied to 312 P. acnes isolates previously characterized by MLST and representing types IA1 (n=145), IA2 (n=20), IB (n=65), IC (n=7), II (n=45), and III (n=30), the multiplex displayed 100% sensitivity and 100% specificity for detecting isolates within each targeted phylogroup. No cross-reactivity with isolates from other bacterial species was observed. This multiplex assay will provide researchers with a rapid, high-throughput, and technically undemanding typing method for epidemiological and phylogenetic investigations. It will facilitate studies investigating the association of lineages with various infections and clinical conditions, and it will serve as a prescreening tool to maximize the number of genetically diverse isolates selected for downstream higher-resolution sequence-based analyses.
