the oil and gas pools formed from since. From the Dongying Formation(Ed) to Neogene, the Shahejie Formation was located in the late diagenetic stage A1~A2; The oil and gas pools formed in a wide scale.
The secondary structure was finally determined by MCD as follows:a triple strand antiparallel β sheet with I20-W26, R37-A43 and V53-S59 as its β strands, a short α helix formed by W30-G35 and four turns formed by P7-K10, C14-G17, K50-V53 and D61-N64.
The result showed that the main HDL-apo AI subform in rabbit serum was apo AI_(?) , the relative percentages of apo AI_1-AI_(?) were 12.49±4.28％, 12.96±4.22％, 13.94±7.28%, 47.14±7.48% and 13.47±4.42%, respectively.
Results All pa-rients were pathologically diag nosed of ureteral papillary transitional cell carcinoma,of which 7 cases were G1 ,10 cases G2 ,9 cases G, ,6 cases were stage O-A,8 cases stage B,7cases stage C and 5 cases stage D.
We use the theory of tilting modules for algebraic groups to propose a characteristic free approach to "Howe duality" in the exterior algebra.
The purpose of this note is to prove, as Lusztig stated, that the Euler characteristic of the variety of Iwahori subalgebras containing a certain nil-elliptic elementnt istcl wherel is the rank of the associated finite type Lie algebra.
In our paper [KR] we began a systematic study of representations of the universal central extension[InlineEquation not available: see fulltext.] of the Lie algebra of differential operators on the circle.
In the present paper we study the remaing nontrivial case, that of a negative central charge-N.
In this note we present a very simple method of proving that some hyperbolic manifoldsM have finite sheeted covers with positive first Betti number.
