The (n,γ) reaction cross-section for the elements Zn, Zr, Sb and Sb, present in the reactor structural/shielding materials, was measured by neutron activation technique in the neutron energy region of 1-2 MeV as very limited data is available in this energy range. Further, the neutron spectrum peaks in this energy region for the fast breeder reactors and proposed accelerator driven sub-critical systems. The natural strontium (Sr) element was used as a neutron flux monitor by considering effective combined reaction cross-section for Sr(n,γ)Sr and Sr(n,n')Sr reactions.

Methods: Orthodontic patients treated at a tertiary care center were the subject of a retrospective analysis.
Objective: The purpose of this study was to compare the efficacy of various remineralizing agents in stopping the early enamel lesions surrounding orthodontic brackets from progressing.
Techniques: Four groups were randomly allocated to a total of 100 participants: the control group (no treatment), calcium phosphate, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and fluoride varnish. Remineralizing chemicals were administered in accordance with manufacturer recommendations, and enamel lesions were created around orthodontic brackets.
Background: Combination vaccines are effective in simplifying complex vaccination schedules involving multiple vaccines. A fully liquid hexavalent diphtheria (D)-tetanus (T)-whole-cell pertussis (wP)- hepatitis B (HepB)-inactivated poliovirus (IPV)-Haemophilus influenzae b (Hib) vaccine (HEXASIIL®), manufactured by Serum Institute of India Pvt.
