2Milk Yield of Holstein Cows Induced into Lactation Twice Consecutively and Lactation Curve Models Fitted to Artificial Lactations显示文摘Nineteen multiparous barren Holstein cows were subjected to an induction of lactation protocol for 21 d administering estradiol cypionate(2 mg kg-1 of body weight(BW) d-1, on day 1 to 14), progesterone(0.10 mg kg-1 of BW, on day 1 to 7), flumethasone(0.03 mg kg-1 of BW, on day 18 to 20) and recombinant bovine somatotropin(rbST; 500 mg per cow, on day 1, 6, 16 and 21). At the end of lactation and with a minimum of a 2-mon dry period, the same cows were again hormonally induced into lactation. Cows in both lactations were not artificially inseminated, they were milked 3 times daily and received rbST throughout lactation. Mean accumulated milk yield at 305 d in milk(DIM) did not differ between the first and second induced lactations((9 710±1 728) vs.(9 309±2 150) kg; mean±SD). Total milk yield((12 707±3 406) vs.(12 306±4 218) kg; mean±SD) and lactation length((405±100) vs.(410±91) d; mean±SD) were not different between the first and second induced lactations. In a second study, 15 empirical models including exponential, power law, yield-density, sigmoidal and miscellaneous models were compared for their suitability by modeling 12-mon(n=334), 18-mon(n=164) and 29-mon(n=22) lactation cycles of Holsteins cows induced into lactation and treated with rbST throughout the lactation. Hoerl(Y= ab1/xxc), Wood(Y=axb exp(cx)) and Dhanoa(Y=ax(bc)exp(cx)) models were equally suitable to describe 12-mon lactations. An exponential model with five parameters(Y=exp(a+bx+cd2+e/x)) showed the best fit for milk yield for 18-mon lactations. The rational model(Y=a+bx/1+cx+dx2) was found to produce the closest fit for 29-mon lactations. It was concluded that, with the protocol used in the present study, multiparous cows respond favorably to a second cycle of induced lactation, with milk yield similar to that experienced during the first cycle. Thus, dairy producers might be able to lengthen the productive life of infertile high producing cows with a renewal of artificial lactation, which would imply an overall reduction in voluntary culling of cows. Also, various equations used to describe the lactation curves demonstrated the potential for fitting monthly milk records of Holstein cows with prolonged lactations and induced hormonally into lactation.Jesus Mellado Edgar Sepulveda Jose E Garcia Alvaro Rodriguez Maria A De Santiago Francisco G Veliz Miguel Mellado 2014Journal of Integrative Agriculture2014,13,6:1

6Periodic surface functional group density on graphene via laserinduced substrate patterning at Si/SiO2 interface显示文摘Controlling the spatial distribution of functional groups on two-dimensional(2D)materials on a micrometer scale and below represents a fascinating opportunity to achieve anisotropic(opto)electronic properties of these materials.Periodic patterns of covalent functionalization can lead to pericxJic potentials in the monolayer;however,creating such superstructures is very challenging.Here,we describe an original approach to the periodic functionalization of graphene induced by substrate patterning using a pulsed laser.Laser-induced periodic surface structures(LIPSS)are produced on silicon wafers with thermally-grown oxide layers.The irradiation conditions for the formation of UPSS confined at the SiO2/Si interface have been unravelled.LIPSS imprint their periodicity to the reactivity of the monolayer graphene placed on the substrate via modulation of its local doping level.This method is clean,straightforward and scalable with high spatial resolution.Karolina A.Drogowska-Horna Inam Mirza Alvaro Rodriguez Petr Kovaricek Juraj Sladek Thibault J.-Y.Derrien Mindaugas Gedvilas Gediminas Raciukaitis Otakar Frank Nadezhda M.Bulgakova Martin Kalbac 2020Nano Research2020,13,9:0

8燃油二次喷射对柴油机燃烧和性能的影响显示文摘在Ricardo Hydra单缸柴油机上,采用一次主喷射+一次后喷射的方法进行了5组燃烧对比试验。示功图和缸内燃烧分析表明,两次喷射有效地延长了等压加热过程,平均有效压力得到较大的提高,NOx排放有一定幅度的下降。邸敏艳 Alvaro Diez Rodriguez Hua Zhao 2010车用发动机2010,,2:0

10燃油2次喷射对柴油机性能的影响研究显示文摘研究了主喷射提前角和后喷射提前角对Ricardo Hydra单缸柴油机动力性能及排放性能的影响。结果表明,当该柴油机主喷射提前角为11°、后喷射提前角为3°时,柴油机最高爆发压力与采用单喷射时最高爆发压力相差不大,但平均有效压力却提高明显;随着喷油提前角的后移,烟度排放增加,NOx排放减少,HC排放增加。分析了主喷射和后喷射时该柴油机燃烧过程。姚勇 Alvaro Diez Rodriguez Hua Zhao 2010汽车技术2010,,4:0
11Grid-connected Converters with Virtual Electromechanical Characteristics:Experimental Verification显示文摘Grid-connected power converters,which are frequently used to link renewable generation plants with the grid,are required to provide a better functionality for large scale integration of renewables.They are expected to be gridfriendly,or even grid-supportive,instead of simply grid-feeding or grid-demanding.This paper designs a synchronous power controller for grid-connected converters in detail,emulating the electromechanical characteristics of synchronous machines and improving even its actual performance,as it is based on a virtual approach.Based on this design,the grid-interfacing units are capable of showing inertia,damping,and droop characteristics as synchronous machines and presenting thus a grid-supporting behavior.The detailed control design and experimental validation on a 10 kW laboratory setup acts as the main contribution of this paper,compared with the existing studies on generator emulation controls.Weiyi Zhang Daniel Remon Ignacio Candela Alvaro Luna Pedro Rodriguez 2017CSEE Journal of Power and Energy Systems2017,3,3:0
