NTSYSpc (Numerical Taxonomy and Multivariate Analysis System) is a simple and light-weight statistical software used for cluster analysis of molecular genetic qualitative data. The broad features of NTSYSpc include similarity/dissimilarity, clustering, graph theoretic methods, ordination, interactive graphics, multivariate tests, geometric morphometrics, and comparison of matrices. This brief video tutorial illustrates how to use NTSYSpc to create a cladogram ( a tree diagram that shows the cladistic relationship between several populations/species ) from a binary matrix. The table made up of 0s and 1s is represented by the binary matrix. On the other hand, 1 denotes the presence of character, 0 denotes the absence of character ( trait ), and a blank area denotes the absence of character.

It is an online free mathematics problem solving tool by Google. Your maths problem will be shared with maths providers ( GeoGebra, QuickMath, Alpertron, Mathway, Symbolab, eMathHelp, Tiger Algebra, Gauthmath, Matrix Calculator, dCode, TutorEva, MathCelebrity, Qanda, CameraMath, ScanMath, Mathforyou, or MathDF ) and processed according to their privacy policies. No other data will be shared. It supports both manual problem typing and scan and upload images (process through OCR technology). We can solve a variety of problems namely linear equations, polynomials, quadratic equations, rational expressions, exponents, complex numbers, trigonometry, inequalities, system of linear equations, radicals, absolute values, logarithms, probably, integrals, derivatives, vectors, and matrices . The rich feature of the tools is that we can get a step-by-step explanation of the problem solving.

Homology or comparative protein structure modeling is a complex process, but with the help of tools like Modeller , it becomes more accessible and efficient. It's fascinating how the program can automatically calculate a model with all non-hydrogen atoms based on an alignment of a sequence to be modeled with known related structures. The input to Modeller are restraints on the spatial structure of the amino acid sequence(s) and ligands to be modeled, and the output is a 3D structure that satisfies these restraints as well as possible. It's amazing how the program can derive restraints from various sources such as related protein structures, NMR experiments, rules of secondary structure packing, cross-linking experiments, fluorescence spectroscopy, image reconstruction in electron microscopy, site-directed mutagenesis, residue-residue and atom-atom potentials of mean force, and even intuition. The program can operate on various spatial features defined by atoms or pseudo at...

BioEdit is a free biological sequence alignment editor. It has an intuitive multiple document interface and offers convenient features that make alignment and manipulation of sequences relatively easy on windows desktop computers. Additionally, there are several sequence manipulation and analysis options and links to external analysis programs that facilitate a working environment, allowing users to view and manipulate sequences with simple point-and-click operations. The BioEdit software provides automated local and web BLAST ( B asic L ocal A lignment S earch T ool) searches with a simple graphical user interface (GUI) to the command-line BLAST program. This is a simple video tutorial on how to construct a custom nucleotide/protein database using BioEdit software to support NCBI BLAST . The tutorial also covers how to perform a query search, specifically pairwise sequence alignment, against the database.

A phylogenetic tree ( a.k.a. , cladogram or dendrogram) is a diagrammatic/graphical representation of the genetical/evolutionary relationship of species/organisms/genes. Phylogenetic tree helps to find the common ancestor. The i nteractive T ree O f L ife ( iTOL ) is an online tool to display and manipulate phylogenetic trees. iTOL offers free access (limited access), standard subscription (unlimited access), and iTOL annotation editor subscription (unlimited and versatile access). It supports user-interactive customizable tree layouts, manual drawing, and annotation. iTOL can visualize trees with 50,000 or more nodes. This is a simple video tutorial for user interactive visualization of phylogenetic trees using the iTOL tool. The iTOL tool produces phylogenetic trees in various formats, such as rectangular, slanting, curved, radial, and curved. It accepts input in Newick, Nexus, or PhyloXML file format.

A phylogenetic tree ( a.k.a. , cladogram or dendrogram) is a diagrammatic/graphical representation of the genetical/evolutionary relationship of species/organisms/genes. It helps to find the common ancestor. Construction of a phylogenetic tree consists of two phases, multiple sequence alignment and computing distance matrix. This is a simple video tutorial for constructing a phylogenetic tree using Molecular Evolutionary Genetics Analysis ( MEGA ) software. The MEGA software produces phylogenetic trees from multiple sequences in various formats: rectangular, slanting, curved, radial, and curved.

Network marketing (a.k.a. direct selling) is a trending business model which replaces the traditional sales and advertising system. It relies on person-to-person sales (chain system) through work from home. Digital marketing (or online marketing) is a way to expand the marketing network through the internet and digital platforms such as PC/laptops and smartphones using digital media and platforms to promote the products. Social media applications place a significant role in sharing product or service details and communicating with persons. Many local and global network marketing companies are emerging rapidly. Some of the most popular network marketing firms are Altos, Amway, Asclepius Wellness, Atomy India, Avon, Biosash, Forever, Future Maker, Galway, Happy Health India, Herbalife India, Highrich, IMC, Indusviva, Keva Industries, Mary Kay, MI Lifestyle, Modicare, Naswiz Retails, Netsurf Network, OK Life Care, Oriflame, RCM, Renatus Wellness, Rodan+Fields, Safe Shop India, Tuppe...
