Standardized ileal digestibility coefficients(SIDC)of nitrogen(N)and amino acids(AA)in two protein sources(soybean meal[SBM]and canola meal[CM])were investigated at six broiler ages(d 7,14,21,28,35,and 42).Two assay diets were formulated to contain either SBM(413 g/kg)or CM(553 g/kg)as the sole dietary AA *** dioxide(5 g/kg)was added as an indigestible marker.A total of 696 male broilers at 1 d old were allotted to 12 replicate cages per age *** assay diet was offered to birds for 4 d prior to the ileal digesta collection on d 7(14 birds/cage),14(12 birds/cage),21(10 birds/cage),28(8 birds/cage),35(8 birds/cage)and 42(6 birds/cage),*** apparent digestibility coefficients were standardized using age-specific basal endogenous AA *** the SBM group,though the SIDC of N tended to be influenced(quadratic;P=0.075)by age,no linear or quadratic response of age effect was observed on the average SIDC of indispensable(IAA)and total AA(TAA).An age effect(quadratic;P<0.05)was observed on the average SIDC of dispensable AA(DAA)in SBM with the highest value recorded at d 7,followed by a decrease from d 14 to 28,which increased beyond d *** SIDC of some individual AA(Arg,Thr,Trp,Cys,Pro)were affected(P<0.05 or P<0.001)in a quadratic manner by *** the CM,the SIDC of N,average SIDC of IAA,DAA and TAA were influenced(quadratic;P<0.05 or P<0.001)by *** SIDC of N and average SIDC of DAA and TAA were higher from d 7 to 14,declined at d 21,and then increased beyond d *** average SIDC of IAA was low between d 7 and 28 and increased *** SIDC of individual AA were affected(linear or quadratic;P<0.05 or P<0.001)by different magnitudes by *** age influence on the SIDC AA was variable,depending on the protein source and *** results demonstrate that age-specific SIDC AA data might need consideration in broiler feed formulations.

Effects of post-processing heat treatments on the microstructure， aging kinetics， and room/elevated temperature mechanical properties of additively manufactured Inconel 718 superalloy were investigated. Scanning electron microscopy (SEM)， electron backscattered diffraction (EBSD)， and X-ray diffraction (XRD)， as well as hardness， tensile， and creep testing were used for characterization. At temperatures higher than 1100 °C， homogenization treatment resulted in the appearance of equiaxed grains by recrystallization and diminishing the dislocation density. The precipitation activation energy for the homogenized aged condition was obtained as 203 kJ/mol， which was higher than the value of ～160 kJ/mol for the as-built IN718 superalloy. Therefore， direct aging resulted in a faster aging response， which led to a significant improvement in tensile properties， as rationalized by the strengthening mechanisms. Direct aging treatment resulted in a higher elevated-temperature ultimate tensile strength (UTS) as well as the optimum creep life and lowest minimum creep rate in comparison with other heat treating routes， which were attributed to the presence of fine and uniformly dispersed strengthening precipitates in conjunction with the high dislocation density.

Nitrogen-rich heterocyclic energetic compounds（NRHECs） and their salts have witnessed widespread synthesis in recent years. The substantial energy-density content within these compounds can lead to potentially dangerous explosive reactions when subjected to external stimuli such as electrical ***, developing a reliable model for predicting their electrostatic discharge sensitivity（ESD） becomes imperative. This study proposes a novel and straightforward model based on the presence of specific groups（-NH2or-NH-,-N = N+-O-and -NNO2,-ONO2or-NO2） under certain conditions to assess the ESD of NRHECs and their salts, employing interpretable structural parameters. Utilizing a comprehensive dataset comprising 54 ESD measurements of NRHECs and their salts, divided into 49/5 training/test sets,the model achieves promising results. The Root Mean Square Error（RMSE）, Mean Absolute Error（MAE）,and Maximum Error for the training set are reported as 0.16 J, 0.12 J, and 0.5 J, respectively. Notably, the ratios RMSE（training）/RMSE（test）, MAE（training）/MAE（test）, and Max Error（training）/Max Error（test） are all greater than 1.0, indicating the robust predictive capabilities of the model. The presented model demonstrates its efficacy in providing a reliable assessment of ESD for the targeted NRHECs and their salts,without the need for intricate computer codes or expert involvement.
