The primary purpose of this study was to investigate the effect of a catalyzed continuously regenerating trap(CCRT)system composed of a diesel oxidation catalyst(DOC)and a catalyzed diesel particulate filter(CDPF)on the main gaseous and particulate emissions from an urban diesel bus,as well as the durability performance of the CCRT system.Experiments were conducted based on a heavy chassis dynamometer,and a laboratory activity test as well as X-ray photoelectron spectroscopy(XPS)test were applied to evaluate the changes of the aged CCRT catalyst.Results showed that the CCRT could reduce the CO by 71.5%and the total hydrocarbons(THC)by 88.9%,and meanwhile promote the oxidation of NO.However,the conversion rates for CO and THC dropped to 25.1%and 55.1%,respectively,after the CCRT was used for one year(~60,000 km),and the NO oxidation was also weakened.For particulate emissions,the CCRT could reduce 97.4%of the particle mass(PM)and almost 100%of the particle number(PN).The aging of the CCRT resulted in a reduced PM trapping efficiency but had no observable effect on the PN;however,it increased the proportion of nucleation mode particles.The activity test results indicated that the deterioration of the CCRT was directly relevant to the increase in the light-off temperatures of the catalyst for CO,C3H8 and NO2.In addition,the decreased concentrations of the active components Pt2+ and Pt4+ in the catalyst are also important factors in the CCRT deterioration.

Summary What is already known about this topic?Perfluoroalkyl substances(PFASs)are persistent organic pollutants,which have multi-organ toxicity and potential health risk to humans.What is added by this report?The most commonly detected PFASs in the Sixth China Total Diet Study(TDS)samples were perfluorooctanesulfonate(PFOS),perfluorooctanoic acid(PFOA),perfluoroundecanoic acid(PFUdA),perfluorodecanoic acid(PFDA),perfluorononanoic acid(PFNA),and 9-chlorohexadecafluoro-3-oxanonane-1-sulfonate(6:2 Cl-PFESA).The mean estimated weekly intakes(EWIs)of PFOA,PFOS,and 6:2 Cl-PFESA in the Sixth TDS were 2.17,2.72,and 2.75 ng/kg body weight per week,respectively.What are the implications for public health practice?The PFASs levels in some food category and dietary exposure still need to be continuously monitored,especially for 6:2 Cl-PFESA.

The lifestyle of trees may seem sedentary,but behind the scenes,various meristems are busy stacking layers of cells in differentdirections,which allows trees to soar to great heights and girths.Procambial cells are formed continuously during"primarygrowth"very close to the shoot apex,guaranteeing the continuityof the vascular system throughout the stem and vertical growth.Primary growth turns,by definition,into"secondary growth"with the advent of the vascular cambium.

The ribosome is a highly conserved molecular machine responsible for protein biosynthesis in all living cells.The ribosomes of all species consist of two unequal subunits,and each of them has a specialized function,peptidyl-transfer for the large subunit(50s or 60S)and mRNA decoding for the small subunit(30S or 40S).The ribosome provides a platform in the inter-subunit space between the two subunits for the binding of mRNA,tRNAs,and different translation factors,and by moving along the mRNA,it reads the genetic information stored in the mRNA codons and elongates the polypeptide chain accordingly.Since its first appearance under electron microscope in the mid-1950s[1],the ribosome has been continuously studied by various structural biology approaches.The first high-resolution structures of ribosomal subunits were determined by X-ray crystallography nearly fifty years after its discovery[2-4],which have provided essential atomic information for understanding the mechanism of protein biosynthesis.In the next fifteen years.
