Virtual Sketch is in where we can draw by just capturing the motion of a colored marker with a camera. One colored object at the tip of the finger is mainly used as the marker. We are here now, using the techniques of computer vision in open cv to build this project. The required language for this project is python due to its more exhaustive libraries and easy to make use of the syntax and but understanding the basics as well as it can be implemented in any open cv supported languages The colour tracking and detection processes are used to achieve the goal of this project. The color marker here used is detected and mask is produced. The next steps of morphological operations on the mask produced those are Erosion and Dilation. Erosion makes the impurities present in the mask to get reduced and Dilation further regains the eroded main mask.

Abstract As the efficiency of the clustered regularly interspaced short palindromic repeats/Cas system is extremely high, creation and maintenance of homozygous lethal mutants are often difficult. Here, we present an efficient in vivo electroporation method called improved genome editing via oviductal nucleic acid delivery (i-GONAD), wherein one of two alleles in the lethal gene was selectively edited in the presence of a non-targeted B6.C3H-In(6)1J inversion identified from the C3H/HeJJcl strain. This method did not require isolation, culture, transfer, or other in vitro handling of mouse embryos. The edited lethal genes were stably maintained in heterozygotes, as recombination is strongly suppressed within this inversion interval. Using this strategy, we successfully generated the first Tprkb null knockout strain with an embryonic lethal mutation and showed that B6.C3H-In(6)1J can efficiently suppress recombination. As B6.C3H-In(6)1J was tagged with a gene encoding the visible coat color marker, Mitf, the Tprkb mutation could be visually recognized. We listed the stock balancer strains currently available as public bioresources to create these lethal gene knockouts. This method will allow for more efficient experiments for further analysis of lethal mutants.



The basic, special, and additional commands for generating two- and three-dimensional graphs are presented. It describes formatting commands for inserting labels, headings, texts, and symbols into a plot, as well as color, marker, and line qualifiers. Graphs with more than one curve and graphs with two Y axes are discussed. The possibilities of creating multiple plots on one page are shown. All the commands studied are presented with examples from the field of mechanics and tribology (M&T). At the end of the chapter, applications are given; they illustrate how to generate 2D and 3D graphs for engine piston velocity, power screw efficiency, engine oil viscosity, and a number of other M&T problems.

The choice of an intravascular cannula (catheter) is a rather difficult and important issue in modern medicine, especially in the anesthesiology and intensive care unit. In today’s market there are many variants of cannulas, which differ in size and material. As for the size of the cannula, the issue is resolved. The American Medical Device Manufacturers Association proposed measuring the outer diameter of cannulas in “gauge” G. The European Standard ISO 10555.5 regulates the outer diameter of cannulas in millimeters and states that each catheter should have a color marker indicating the nominal outer tube. Color marking helps to find quickly the right size of cannula in extreme situations. The marking of cannulas in “gauge” G and mm is made on the packaging of the product. As to the choice of material, the question remains open. Therefore, in this article, we decided to cover the issue of choice of intravascular cannulas on the material. We have also developed some practical guidelines that facilitate catheterization of peripheral veins and allow cannula to stay longer in the vein. This article will be interesting for doctors and nursing staff.

Abstract Root and stem rot caused by Rhizoctonia solani is a serious fungal disease of sugar beet and dry bean production in Nebraska. The objective of this study was to analyze morpho-genetic diversity of 38 Rhizoctonia solani isolates from sugar beet and dry bean fields in western Nebraska over 10 years. Morphological features and ISSR-based DNA markers were used to study the morphogenetic diversity. Fungal colonies were morphologically diverse in shapes, aerial hyphae formation, colony, and sclerotia color. Marker analysis using nineteen polymorphic ISSR markers showed polymorphic bands ranged from 15 - 28 with molecular weight of 100bp to 3kb. Polymorphic loci ranged from 43.26 – 92.88%. Nei genetic distance within the population ranged from 0.03 – 0.09 and Shannon diversity index varied from 0.24 – 0.28. AMOVA analysis based on ΦPT values showed 87% variation within and 13% among the population with statistical significance (p<0.05). Majority of the isolates from sugar beet showed nearby association within the population. A significant number of isolates showed similarity with isolates of both the crops suggesting their broad pathogenicity. Isolates were grouped into three different clusters in UPGMA based cluster analysis using marker information. Interestingly, there was no geographical correlation between the isolates. Principle component analysis showed randomized distribution of isolates from the same geographical origin. This information may help in molecular pathotyping of the pathogen for better disease management.
