(4)Therewas a significant (P<0.05) positive correlation between the dietary CP level and thevolatile basic N(VBN) and ammonia N(AN) contents in colonic digesta, respectively. How-ever, the VBN and AN contents in cecal digesta were not affected(P >0.05) by the dietaryCP level.

Nowadays, with the rapid development of sc ience and technology and kno wledge renewal, many countries regard teachers' continuing education as a basic n ational policy.

The results showed that under the condition of the same amount of fertilizer, the treatment (A4) of half basic N fertilizer and half top-dressing fertilizer had the highest yield, and there was a significant difference with treatments A1 and A2 which were applied with 100% and 70% basic N fertilizer treatment respectively (Table 1).

As in polar aprotic solvents cationic homoconjugation phenomenon has been found to be present for sufficiently basic N-oxides.

For integers 1 ≤ m >amp;lt; n, a Cantor variety with m basic n-ary operations ωi and n basic m-ary operations λk is a variety of algebras defined by identities λk(ω1(

Remarkably, the more basic N-methylimidazole ring in one of the complexes facilitates the rate-determining productreleasing phase of the catalytic reaction.

Acidic and basic Nα-lauroyl-L-arginine dipeptides from pure amino acids

Our results suggest that the predicted basic N-terminal α-helix is involved in RNA binding, while the central domain is involved in duplex formation.

The multiple point trials were conducted using square current rotation and optimaldesign in Lingtai and Jinchuan for 7 years.The year patterns of different soil base mois-ture were obtained.A mathematical model of the cultivation technical package of winterwheat on different soil fertilities(seeding time,seeding rate,an amout of N and P fertil-izer,row spacing,ratio between basic N fertilizer and top-dressing)was developed.Through the analysis,the best indexes of cultivation technical package of...

In this paper, the formulation of middle-phase microemulsion systems with a aonionic surfactant selected, OP-10, for EOR is researched by using the equation coefficient approach. The composition of the systems studied is: OP-10, a basic(n-butanol) and aa additional(n-hexanol) alcohols, and sodium chloride constitute the aqueous phase; normal alkanes C6-C12 serve as the oil phase. Following equations for the optimum salinity of the aqueous phase, S~*, in g/100ml are established, lnS~* = 0.0536(ACN)...

The N-banding patterns in ninety-two cultured barleys (Hordeum vulgare L. ) from various regions of the world were investigated by the N-banding techniques. The polymor-phiism of the N-banding patterns was widespread. Two different banding pattern variants existed in chromosomes 7, and three in chiomosome 4 and 6, four in chromosome 5, five in chromosome 1, six in chromosome 2, and eight in chromosome 3. total of 59 different N-banding patters has been found. The varieties with common...

The varieties with common basic N-nanding pattern (1A, 2A, 3A, 4A, 5A, 6A, 7A) accounted for 11. 96% of studied barleys, the relation-ships between N-banding pattern and geographical region were discussed.
