A mechanism is proposed by which speciation may occur without the need to postulate geographical isolation of the diverging populations.Closely related species that occupy overlapping or adjacent ecological niches often have an almost identical genome but differ by chromosomal rearrangements that result in reproductive isolation.The mitotic spindle
In modern conditions, the housing construction sector is dynamically developing and transforming under the influence of the turbulent processes of our time: globalization, digitalization, platformization, greening, etc.The purpose of the article is to identify new innovative forms Boys athletic-sweaters of investment in housing construction and the
Arsenic is a ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [As(III)] and arsenate [As(V)].Arsenic resistance in Synechocystis sp.strain PCC 6803 is mediated by the arsBHC operon and two additional Plant Stands arsenate reductases encoded by the arsI1 and arsI2 genes.Here we describe the genome
Eelgrass (Zostera marina) is a monocotyledonous plant found in seawater (seagrass).Eelgrass has many physiological characteristics that enable it to cope with salinity, hyperosmolarity, and hypoxia, as well as to live in marine environments.Germinating seedlings are sensitive to high levels of salinity, which inhibit germination and seedling growth
This paper presents the method of determining and characterizing of a piezoelectric stator profile that applying in a piezoceramic ultrasonic motor with the consideration of heat generated.The piezoceramic ultrasonic motor is driven by the vibration of the piezoelectric element in order to ignite a motion.The harmonic and transient analysis of fini
