Bulk phase polymerization of propylene with a 4th generation of Ziegler-Natta catalyst was kinetically investigated by means of heat flow calorimetry.The assumptions and modifications on isothermal calorimetric method were demonstrated.Our calibration method showed that heat exchange with the reactor cover plate is not constant over time.Therefore,
PTFE/Al/MoO3 composites with MSM different PTFE concentrations were prepared by mold pressing and sintering.The materials were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), in addition, the properties of the composites under quasi-static compression and dynamic impact were also studied.The results indicate that, t
Expanding free HIV testing service (HTS) access to include private clinics could increase testing rates.A donor funded programme, GP Care Cell, offered free HIV testing at selected private doctor-led clinics but uptake was low.We investigated whether HTS demand creation materials that used behavioural economics principles could increase demand for
Hematopoietic stem cell transplantation (HSCT) is a common method for patients such as hematologic malignancies.However, HSCT MAG W K generally has a higher risk of secondary solid cancer development.The aim of this study was to emphasize the need for lifelong follow-up of oral secondary solid cancer.The patient was a male who underwent HSCT for ch
Aims: This in-vitro study aimed to compare the fatigue deformation of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) clasps by mechanical cycling test simulating ten years of use.Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar; it is divided into 24 Co-Cr clasps, and 48 PEEK Wiref
