Meiosis is the cell division that halves the genetic component of diploid cells to form gametes or spores.To achieve this, meiotic cells undergo a radical spatial reorganisation of chromosomes.This reorganisation is a prerequisite for the pairing of parental homologous chromosomes and the reductional division, which halves the number of chromosomes
Background: Complicated crown fracture is a tooth fracture that involve enamel, dentine and pulp.The incidence of complicated crown fracture ranges from 2% to 13% of all dental injuries and the most commonly involved teeth are the maxillary central incisors.Various treatment modalities are available depending on the clinical, physiological and radi
To study the energy dynamic change law of moisture-contained coal in the process of liquid nitrogen freezing, a self-developed acoustic emission (AE) experimental system for the whole process of liquid nitrogen frozen coal was utilized to analyze the characteristics and the change laws of AE energy dissipation BLUE BERRY EYEBRIGHT in the whole proc
The study of natural convection from a heat source located at the bottom of partially top vented enclosure is presented.Air cooling for electronic components situated at the bottom of a top vented enclosure is studied theoretically.The flow was assumed to be laminar, steady and of constant physical properties.The process was described by the contin
