In.the presen. study correlation. regression.an. path an.lyses were carried out to decide correlation. amon. the agro- n.mic traits an. their con.ribution. to seed yield per plan. in.Crambe abyssin.ca. Partial correlation.an.lysis in.icated that plan. height (X1) was sign.fican.ly correlated with bran.hin. height an. the n.mber of first bran.hes (P 2) was sign.fican.ly correlated with pod n.mber of primary in.lorescen.e (P 3) was sign.fican.ly correlated with n.mber of secon.ary bran.hes (P -grain.weight (P 4) was sign.fican.ly correlated with seed yield per plan. (P 7) was sign.fican.ly correlated with seed yield per plan. (P -grain.weight (P -grain.weight (X8) was sign.fican.ly correlated with seed yield per plan. (P -grain.weight con.ributed sign.fican.ly to seed yield per plan. at P 7) an. 1000-grain.weight (X8) to seed yield per plan. (Y) is Y = 0.006 X7 + 1.222 X8 - 7.191. The path coefficien. of pod n.mber per plan. to seed yield per plan. was 0.967 an. that of 1000-grain.weight was 0.194. The determin.tion.coefficien. of pod n.mber per plan. an. 1000-grain.weight to seed yield per plan. was 0.983 an. the determin.tion.coefficien. of other agron.mic traits was 0.130. Coefficien. of varian.e in.icated that the len.th of primary in.lorescen.e showed the greatest variation. followed by seed yield per plan., pod n.mber per plan., n.mber of secon.ary bran.hes, bran.hin. height, pod n.mber of primary in.lorescen.e, n.mber of first bran.hes, seed yield per plot, 1000-grain.weight an. plan. height. It was suggested that seed yield per plan. in.Crambe might be improved by in.reasin. the pod n.mber per plan. through selection.or cultivation. but the n.gative correlation.between.pod n.mber per plan. an. 1000-grain.weight also n.eds to be con.idered.

Challen.es an. prospects for con.umer acceptan.e of cultured meat

Journ.l of In.egrative Agriculture 2015年第2期14卷 285-294页

Con.umer acceptan.e of cultured meat is expected to depen. on.a wide diversity of determin.n.s ran.in. from techn.logyrelated perception. to product-specific expectation., an. in.ludin. wider con.extual factors like media coverage, public in.olvemen., an. trust in.scien.e, policy an. society. This paper discusses the case of cultured meat again.t this multitude of possible determin.n.s shapin. future con.umer acceptan.e or rejection. The paper also presen.s in.ights from a primary exploratory study performed in.April 2013 with con.umers from Flan.ers（Belgium）（n.180）. The con.ept of cultured meat was on.y kn.wn.un.ided） by 13% of the study participan.s. After receivin. basic in.ormation.about what cultured meat is, participan.s expressed favorable expectation. about the con.ept. On.y 9% rejected the idea of tryin. cultured meat, while two thirds hesitated an. about quarter in.icated to be willin. to try it. The provision.of addition.l in.ormation.about the en.iron.en.al ben.fits of cultured meat compared to tradition.l meat resulted in.43% of the participan.s in.icatin. to be willin. to try this n.vel food, while an.ther 51% in.icated to be ‘maybe＇ willin. to do so. Price an. sen.ory expectation. emerged as major obstacles. Con.umers eatin. mostly vegetarian.meals were less con.in.ed that cultured meat might be healthy, suggestin. that vegetarian. may n.t be the ideal primary target group for this n.vel meat substitute. Although exploratory rather than.con.lusive, the fin.in.s gen.rally un.erscore doubts amon. con.umers about tryin. this product when.it would become available, an. therefore also the challen.e for cultured meat to mimic tradition.l meat in.terms of sen.ory quality at an.affordable price in.order to become acceptable for future con.umers.

This article studies mobile edge computin. techn.logies en.bled by un.an.ed aerial vehicles(UAVs) in.disasters. First, con.iderin. that the groun. servers may be damaged in.emergen.y scen.rios, we proposed an.air-groun. cooperation.architecture based on.ad-hoc UAV n.tworks. We defin.d the system cost as the weighted sum of task delay an. en.rgy con.umption.because of differen. delay sen.itivity an. en.rgy sen.itivity tasks in.emergen.y commun.cation.n.tworks. Then. we formulated the system cost-min.mization.problem of task schedulin. an. multi-UAV deploymen.s. To solve the proposed mixed in.eger n.n.in.ar programmin. problem, we decomposed it to two sub-problems that were solved by proposin. a swap matchin.based task schedulin. sub-algorithm an. a successive con.ex approximation.based multi-UAV deploymen. sub-algorithm. Accordin.ly, we propose a join. optimization.algorithm by iteratin. the two sub-algorithms to obtain.a low complexity sub-optimal solution. Fin.lly, the simulation.results show that(i) the proposed algorithm con.erges in.several iteration., an.(ii) compared with the ben.hmark algorithms, the proposed algorithm has better performan.e of reducin. task delay an. en.rgy con.umption.an. achieves a good tradeoff between.them for diverse tasks.
