Agriculture is an important industry in Kazakhstan that ensures the stability of economic development.Within the northern regions of the republic, crop production received special development.The relevance of studying the impact of long-term fluctuations in precipitation on crop yields increases taking into account the projected trends in climate c
Ribonucleotide reductase M2 (RRM2) is a small subunit in ribonucleotide reductases, which participate in nucleotide metabolism and catalyze the conversion of nucleotides to deoxynucleotides, maintaining the dNTP pools for DNA biosynthesis, repair, and replication.RRM2 performs a critical role in the malignant biological behaviors of cancers.The str
Introduction: Coronavirus disease 2019 (COVID-19) pandemic has caused immense loss of lives, enormous devastation, and has affected lives globally.Timely diagnosis is necessary to contain its spread.While it is important to test symptomatic individuals and high-risk contacts through reliable and confirmatory test (nucleic acid amplification test [N
The cone bit is Flea the most principal rock breaking tool in drilling engineering.The statistical analysis of field data shows that the early damage and failure of sliding bearing is one of the main reasons that affect the service life and performance of the cone bit in the real drilling process.Aiming at the complex working environment of cone bi
A new surface modification for bio-titanium alloy products by electron beam (EB) polishing is proposed.In this EB polishing method, high energy density EB can be irradiated without concentrating the beam.Therefore, large-area EB with a Toner Reload Kit maximum diameter of 60mm can be used for instantaneously melting or evaporating metal surface.Exp
