Paint a violet with watercolors

Paint a violet with watercolors. Flowers, what an excellent subject for a painting! Fresh, colorful, they manage to lift our spirits even in the saddest situations and are an excellent gift. For both a woman and a man! Who said men don’t like flowers? The article you are about to read is made in collaboration with Federica “Fede Creativa,” Together, we will show you how to make a floral watercolor.

How to paint a flower with watercolors: the Pansy

Pansy, also known as Pansé, is one of perhaps the most common flowering plants. Yet if we look closely, we realize how attractive its flower is and suitable to be painted in watercolor. The flower has 5 jagged petals, and in many cases, the 2 rear petals are entirely different in color and details: some combinations are truly unique! To get started, let’s paint the simpler versions. We can then use the same drawing to paint other more complex variants.

The material needed to paint a viola

Paint a violet with watercolors

Below you will find the list of materials used in this article. For each product, you will find the link to the page with all the technical information.

Let’s start with the flower design

Let’s start by transferring the design to the watercolor sheet. You can draw it freehand, or you can download it (see image at the bottom of the article), detect it with tissue paper, and bring it back to the watercolor sheet with the old pencil method: fill the drawing on the back of the tissue with the pencil, go over from the right side pressing lightly to release the trace on the watercolor paper; finish the drawing.

We prepare the first colors

Now that the drawing is ready, we block it on our tablet, and then with the rubber bread, we lighten the stroke so that the pencil is almost not visible anymore when the work is finished. Finally, we mask those details that must remain white with the special masking liquid (I used the Schmincke pen, whose stroke is exact and thin). If you prefer, also mask the minor flaps of the petals.

We paint the first flower

Proceed by wetting the first petal carefully with the Da Vinci brush nr. 8. At first, I used the no. 8 to wet and 2 to paint. I later realized that # 8 is highly accurate, and therefore I also often used it to paint the base of petals and leaves, making the job faster! Wait a few moments, and then start tapping some purple color around the center of the flower. If the color spreads too quickly, allow the paper to dry for a while longer. Create a semicircle at the base of the petal and then extend the radius strokes outwards, trying to give a curved and well-distributed effect, with some longer “tips.”

Without waiting for the sheet to dry, tap the outer edges of the petal with cobalt, taking care to leave white areas. Finally, if the paper is still a little damp, tap a little purple at the base of the petal and around the small flaps at the top to intensify the color. 

It is a very delicate step and could give rise to nasty stains (as indeed happened to me with the first petal!) If you are unsure, do not do it, and let it dry. It can intensify later. Wet the second and then the third petal and proceed in the same way. Remember not to paint the minor flaps of the petal, but if that happens, it’s not a problem. They don’t have to stay white. When the work is finished, it is sufficient that they are lighter and contrast with the rest of the petals.

As you can see below, at this point, I started to use the bigger brush with ease. Continue with the 2 rear petals. This pansy variant has blue-white back petals, so I’ve colored them mostly with cobalt and a few hints of purple. If you like to add pops of color, also create some shades with turquoise.

Here’s how we can fix it:

  • Wait for the paper to dry completely.
  • Scrub carefully with a flat and slightly damp brush.
  • Finally, press a soft tissue by dragging a little inwards.

Let’s paint the flower orange

As we did previously with the purple flower, create a semicircle at the base of the petal with the orange color, and then stretch more or less long strokes following the movement of the petal. Touch the outer edges as well, creating other colored areas. Return after a few moments on some points by tapping to accentuate the color. The red color enriches the central part by drawing new lines. Be careful not to use a mixture that is too rich in water not to damage the previous work. If in doubt, let it dry and wet again.

The final touches

The thin brush adds outlines to the drawing in general, creating light and well-marked strokes to give depth (always in the color tone of the base element). Let’s take this opportunity to fix some imprecise contours!

Original drawing and images to inspire you

Below you will find the original drawing made by Federica that you can reproduce before starting to paint. We also add some photos to use as a reference for flowers and leaves!

What is a binary search tree in Data structure?

Published

on

Binay search tree is a class of Binary trees in which all nodes are arranged in a specific order. A binary search tree is also called an ordered binary tree. 

Features of Binary search tree:

  • In a binary search tree, each node in the left subtree has a value less than or equal to the value of the root.
  • In the same way, each node on the right subtree has a value greater than or equal to the value of the root.
  • This rule is repeated to all the right and left subtrees until it ends. 

What are the advantages of using a binary search tree in Data Structure?

  • A binary search tree makes the search easy and efficient as at every step we get a hint if the desired value is located at the right subtree or left subtree. 
  • A binary search tree is musch more efficient than an array or linked lists, as in the process of searching, at every step half subtree is removed. In a binary search tree, it takes o(log2n) time to complete the search. The worst-case time to make a search is  0(n). Where n is the number of elements. 
  • The insertion and deletion operation also becomes easy with a Binary search tree as compared to a linked list and array. 

Attributes of binary search tree:

Binary search trees are made up of nodes and have the following attributes:

  • Each node of a binary search tree is represented in a parent-child relationship.
  • Each parent node has a minimum of zero and a maximum of two subnodes on the right and left sides.
  • Each subtree also has sub-branches on their left and right sides. 
  • Each node of a binary search tree is linked with key-value pairs. 
  • The values of nodes on the left subtree are smaller than the value of the parent node.
  • The values of nodes on the right subtree are greater than the value of the parent node 

Types of Binary Trees:

There are four types of binary trees, which are:

  1. Complete Binary tree
  2. Full Binary Tree
  3. Skewed Binary Tree
  4. Extended Binary Tree
  1. Complete binary tree:

In a complete binary tree all the levels of the trees are filled. All internal nodes have two children in a complete binary tree. All the leaf nodes of a complete binary tree are at the same level. 

IMG_256

At level 2 there must be 4 nodes and level 3 has 8 nodes. 

  • Full Binary Tree:

In a full Binary tree, each node has two or zero sub-nodes. A full binary tree is also called a Strictly Binary tree.

IMG_256
  • Skewed Binary Tree :

In a Skewed binary tree, most of the nodes have either left sub nodes or right subnodes.

IMG_256

Left Skewed tree- In a left Skewed tree, all the nodes have left subnodes without having right subnodes. 

Right Skewed tree – In a right Skewed tree, all the nodes have right subnodes only without having left subnodes. 

  • Extended Binary tree: 

In an extended binary tree, every empty subtree is replaced with special nodes. Each special node is called an external node and the nodes from the original tree are called an internal node. Each internal node has two children and the external node is a leaf in an extended binary tree.

Advances in Biotech Engineering and Manufacturing

In the last few decades, the rate of biotechnological development has accelerated rapidly, so much that the field is continually being showered with new advancements, improvements, and forward leaps. Disruptive technology is developing dramatically – with some anticipating an increment of 400% through the next seven years – and biotech is one of the significant ventures to watch through 2021. 

Here’s a glance at a few of the previous year’s key accomplishments in the biotech business. 

#1: Biosensors 

Medical technology is turning out to be progressively intuitive. And one such important addition that will shape the business over the following decade is biosensors. We align and intend biosensors to follow different biosignatures. Biosensors transform how we screen our wellbeing, including circulatory strain, heartbeat, breathing, and internal heat level. 

One biotech development organization that is driving the way is Sensible Medical. They’ve created a vest monitoring unit to measure the amount of fluid in the lungs of cardiovascular patients. If the fluid concentration hits dangerous levels, this technology can send an instant alarm to the doctors and healthcare staff, saving many lives. 

#2: 3-D Bioprinting 

Another fascinating development in the biotech advancement area is 3-D bioprinting. 3-D printing was one of the significant accomplishments during the 2010s. Also, the following stage is no less progressive. By utilizing living cells, this technology can make different human body parts like heart valves, skin, and ligaments for use in medication. 

Apart from making life-saving medications and pills, bioprinting can also make whole organs, for example, hearts or livers developed from a patient’s body cells. The capacity to print human organs will likewise have applications in medical exploration and study, as it will provide a better and more holistic approach with exact specimens. 

#3 Bioplastics

Natural and environmental concerns are rapidly turning into a significant interest and concern. Individuals are progressively aware of the materials they use in their everyday lives. One material that has seen the most sensational change in public cognizance is plastic. Assessments express that over 12.7 million gallons of plastic enter the sea every year. It takes many years to die down and poses an enormous threat to marine life. We devised new methodologies to reduce our dependence on plastic. One such technology to emerge out of the biotech development has been the advancement of Bioplastics. 

There was a need for natural materials, which will biodegrade over time or will not hurt animals. Surveys around the world show that utilization of bioplastics may increase by 20% every year. These materials are undeniably less harmful to the climate and function significantly than standard plastics.

#4 Synthetic Biotechnology

A virtually inconceivable capacity to comprehend and compose genomes enables BioTech innovators and corporations to build products better than ever. Furthermore, synthetic biotechnology allows for better uniformity and accuracy by altering cells at the genomic levels. Businesses in regenerative medicine focus on challenges spanning from computerized drug design to cellular farming and microbiome solutions. Bacterial cell industries yield a significant amount of Bacterial cell factories, provide a high yield of essential biochemicals for pharmaceuticals, textiles, and food technology. Companies are also exploring mammalian regenerative technology solutions alongside microorganisms.

#5 Bioenergy

Alongside bio-plastics, biofuels will likewise see an increment in production and their importance in the overall biotech industry. Power and heat generation using biotech sources will grow consistently at around 7% every year. Using biofuel will rise by 7% until 2021. As this technology becomes more accepted and resilient in the business sectors, its effectiveness and creation will consistently grow until it is ready to battle its chemical contemporaries. 

Many urban areas in Europe now have vehicles run on biofuels either wholly or to some degree. Aemetis, a biofuel organization situated in California, is one organization to watch out for. The organization holds offices in the region that produce 60 million gallons of biofuel a year, just as another treatment facility on the eastern ghats of India that produces 50 million gallons.

#6 Gene editing

Just a few years ago, sequencing the human genome was an enormous venture for medical science. Many believed it to be the zenith of biological exploration. Today, sequencing your genome has never been less expensive, dropping from $95 million to only $950 in recent years. 

As scientists find a solid understanding of genes and DNA, they gain more control over its modification. What’s more, gene editing remains perhaps the most flourishing domain in the biotech business. 

Gene modification pioneers like CRISPR Therapeutics from Switzerland utilize gene editing to help people suffering from hereditary diseases. 

Their latest program, called CRISPR/Cas9, cures genetic diseases from the diagnosis stage to the ultimate treatment. This program allows them to monitor genetic disorders before birth, which is very helpful for in-vitro patients. 

#7 Virtual and augmented reality (VR & AR)

We wrap up this article with something that might appear to be more qualified to computer and mobile tech. However, we also cannot neglect the use of VR and AR in biotech development. 

These frameworks work across different clinical fields. For instance, by helping specialists during sensitive operations or aiding patients recuperating from injury. VR and AR permit individuals to analyze 3-D portrayals of the human body and its different parts. The augmented creates a more compelling exhibition of medication and its impact and provides proper support to surgeons during an examination. At the emergency clinics, patients can learn about their ongoing treatment, which helps them stay calm. Also, they can see what their future might look like. 

The future of biotechnology and biotech development is now turning out to be a flourishing and life-changing realm. New regions and fields are opening up continuously, bringing the tremendous potential for advancement and change. What’s more, with this regularly comes significant discussion around the moral ramifications of its use. As we move towards the end of 2021, we’re all extremely eager to experience the new wonders of biotechnology.
