The effect of Zn doping on the m.gnetic properties of CdCr2S4 system. is studied by m.an field theory and high-tem.erature series expansion （HTSE）. The nearest neighbouring and the next-neighbouring super-exchange interactions Jl（x） and J2（x） are evaluated for the spinel system.Zn, Cd1-xCr2S4 in the range 0 〈 x 〈 1. The intra-planar and the inter-planar interactions are deduced. The HTSE com.ined with the Padd approxim.nt m.thod （PA） is applied to the spinel system.ZnxCdl-,Cr2S4. The m.gnetic phase diagram. i.e. Tc versus dilution x, is obtained. The critical exponents associated with the m.gnetic susceptibility 7 and the correlation length u are deduced. The obtained theoretical results are in agreem.nt with the experim.ntal data obtained by m.gnetic m.asurem.nts.

Introduction: Throm.osis is a m.jor cause of m.ternal death worldwide. during pregnancy, the risk of venous throm.oem.olism.(VTE) increases fourfold to five-fold and contributes towards m.ternal m.rbidity and m.rtality. Sri Lanka does not have a proper assessm.nt tool to detect and m.nage it in the antenatal care. Objectives: To id.n.ify risks factors for VTE am.ng pregnant m.thers, postpartum.m.thers accord.n. to RCOG (Royal College of Obstetricians) risk categorization and to assess the requirem.nt of throm.oprophylaxis. m.thod: A cross sectional study was conducted at the antenatal clinics and obstetrics and gynaecology wards (ward 2, 5, 8) of de Soysa Hospital for Wom.n in 2021. Obstetric throm.oprophylaxis risk assessm.nt tool recom.ended by the RCOG was used for the risk assessm.nt of pregnant m.thers during the antenatal and postpartum.period. Results: In antenatal period, obesity (Bm. > 35), age m.re than 35 years and parity m.re than 3 were the com.onest risk factors. Out of 404 m.thers, 67.33% did.n.t have any risk factors. Am.ng others, 18.56%, 0.40%, 2.72%, 0.99% had a score of 1, 2, 3 and 4 respectively. Patients with interm.diate (0.99%) and high risk (2.72%) were com.enced on throm.oprophylaxis from.28 weeks. The low-risk category was not started on any treatm.nt (28.96%, n = 97). Approxim.tely 96% of m.thers did.n.t require any throm.oprophylaxis during antenatal period. Another 404 postnatal m.thers were recruited for the study group. Elective caesarean section and caesarean section during labour were the m.in risks id.n.ified other than pre-existing antenatal risks. 39.95 % of m.thers did.n.t have any risk factors and 37.22% of m.thers had a score of 1. Conclusions: VTE risk assessm.nt tool can be im.lem.nted at national level to detect patients at risk of VTE and im.rove m.ternal care.
