RNA-protein cross-links were introduced into E. coli 30S ribosomal subunits by reaction with 2-iminothiolane followed by a mild ultraviolet irradiation treatment. After removal of non-reacted protein and partial nuclease digestion of the cross-linked 16S RNA-protein moiety, a number of individual cross-linked complexes could be isolated and the sites of attachment of the proteins to the RNA det...

OBJECTIVE The National Population Policy aims to expand voluntary and informed use of contraceptive services. This paper examines the determinants of use of female sterilisation versus other contraceptive methods in rural Bihar, one of the most socially and economically deprived states in India. METHODS Data for 1378 ever-married women aged 15-49 years in rural Bihar, who are currently using ...

In this paper we study a very general quadratic integral equation of fractional order. We show that the quadratic integral equations of fractional orders has at least one monotonic solution in the Banach space of all real functions defined and continuous on a bounded and closed interval. The concept of a measure of noncompactness related to monotonicity, introduced by J. Banaś and L. Olszowy, a...

Most streams receive substantial inputs of allochthonous organic material in the form of leaves and twigs (CPOM coarse particulate organic matter). , Mechanical and biological processing converts this into fine particulate organic matter (FPOM). Other sources of particles include flocculated dissolved matter and soil particles. Fungi are known to play a role in the CPOM conversion process, but ...

Imidacloprid, acephate, and carbaryl are common insecticides that extensively used in planting mango, a well-known fruit Vietnam, to ease mango hopper issues. The accurate detection of pesticide residues is critical for export meet quality criteria. This study developed novel SERS platform by using polydimethylsiloxane (PDMS) simulate the rose petal structure incorporated with silver coating la...
