Background Low crude protein(CP)formulations with supplemental amino acids(AA)are used to enhance intestinal health,reduce costs,minimize environmental impact,and maintain growth performance of ***,extensive reduction of dietary CP can compromise growth performance due to limited synthesis of non-essential AA and limited availability of bioactive compounds from protein supplements even when AA requirements are ***,implementing a low CP formulation can increase the net energy(NE)content in feeds causing excessive fat *** supplementation of functional AA,coupled with low CP formulation could further enhance intestinal health and glucose metabolism,improving nitrogen utilization,and growth *** experiments were conducted to evaluate the effects of low CP formulations with supplemental AA on the intestinal health and growth performance of growing-finishing *** In Exp.1,90 pigs(19.7±1.1 kg,45 barrows and 45 gilts)were assigned to 3 treatments:CON(18.0%CP,supplementing Lys,Met,and thr),LCP(16.0%CP,supplementing Lys,Met,thr,trp,and Val),and LCPt(16.1%CP,LCP+0.05%SID trp).In Exp.2,72 pigs(34.2±4.2 kg BW)were assigned to 3 treatments:CON(17.7%CP,meeting the requirements of Lys,Met,thr,and trp);LCP(15.0%CP,meeting Lys,thr,trp,Met,Val,Ile,and Phe);and VLCP(12.8%CP,meeting Lys,thr,trp,Met,Val,Ile,Phe,His,and Leu).In Exp.3,72 pigs(54.1±5.9 kg BW)were assigned to 3 treatments and fed experimental diets for 3 phases(grower 2,finishing 1,and finishing 2).treatments were CON(18.0%,13.8%,12.7%CP for 3 phases;meeting Lys,Met,thr,and trp);LCP(13.5%,11.4%,10.4%CP for 3 phases;meeting Lys,thr,trp,Met,Val,Ile,and Phe);and LCPG(14.1%,12.8%,11.1%CP for 3 phases;LCP+Glu to match SID Glu with CON).All diets had 2.6 Mcal/kg *** In Exp.1,overall,the growth performance did not differ among *** LCPt increased(Pthe duodenum and *** LCP and LCPt increased(Pt-1,4F2hc,and B0At exp

Can We Estimate the Impacts of Fixed Links Using Current transport Models?Experiences from Concept Evaluations of Fixed Links on E39

引用

Journal of traffic and transportation Engineering 2024年第2期12卷 92-106页

作者： trude tørset Department of Civil and transport Engineering Norwegian University of Science and technology 7491 trondheim Norway

transport analysis and impact evaluations are important input for decisions about infrastructure *** impacts on transport from fjord crossing tunnels or bridges are the foundation for the cost benefit analysis,and also the basis for estimating the income from toll *** on experiences from concept evaluations of several fixed link projects on E39,and an ongoing overall analysis,we question the results from transport analysis made by the official tools for such analysis:the RtM(regional transport model)which estimates the demand for trips below 10 km,the NtM(national transport model),for trips of 10 km or more,and the freight transport *** the NtM and the freight transport model are integrated in the RtM in the net assignment *** will demonstrate strengths and weaknesses in the transport models by showing contra intuitive or questionable results using the model as it *** following questions arose as the initial results from the transport model were presented:Are the transport models able to capture immediate as well as long-term impacts?How would different assumptions about the monetary costs on these projects affect the forecasted demand and the cost benefit analysis?Are there other and wider ranges of impacts,if the analysis covers the total coastal highway as a whole,compared to evaluating impacts of each fixed link project individually?Do we have enough data to include transport effects of wider impacts of the fixed link projects?We had to deal with these questions in the concept evaluations carried out for the various fixed links project and in the current overall *** would like to suggest improvements in the analysis tools and emphasize requirements for knowledge about impacts of fixed links projects.

OXIDE MEtALLURGY-ItS PURPOSES AND PRACtICAL APPROACHES

引用

Acta Metallurgica Sinica(English Letters) 1998年第2期11卷 79-86页

作者： Z.t.Ma D.Janke Freiberg Univ of Mining and Technology Germany

Under certain conditions, nonmetallic inclusions such as oxides, sulfides, nitrides and carbides are no longer harmful to steel service properties. With the new concept of oxide metallurgy, these properties can be improved by generating fine oxide inclusions which serve as heterogeneous nuclei for sulfide and fine ferrite. A novel continuous casting (CC) process is expected to be created with the utilization of oxide metallurgy. this is also useful for the forthcoming technologies of direct rolling and near-net-shape casting. the main idea of oxide metallurgy consists of an alternative oxidation technology. It is based on steels treated by complex metals such as ti, Zr, ti-Zr alloys and rare earth metals. the selected deoxidants should follow the required conditions which are concluded in this paper.
