Abstract:
The scientific and reasonable performance evaluation is advantageous to promote the comprehensive management level of engineering projects. Benefited from constrictive and fluctuant of wavelet transform and self-study, self-adjustment and nonlinear mapping functions of wavelet neural network (WNN), and based on the existing assessment method and the index system, the performance evaluation model of engineering project management is established. One company is taken as the study object for this model. Compared with the conventional method, the influence of human factor is eliminated, thus the objectivity of the measure results is increased. A satisfactory result is concluded, thus a new ap-proach is presented for engineering project management performance evaluation.

Abstract:
Molecularly imprinted polymers (MIPs) represent a new class of materials possessing high selectivity
and affinity for the target molecule. They have been utilized as sensors, catalysts, sorbents
for solid-phase extraction, stationary phase for liquid chromatography, mimics of enzymes, receptors,
and antibodies. In this research, molecular imprinted polymers (MIPs) for luteolin were prepared
using acrylamide, 4-vinylpyridine and 1-allyl-piperazine as functional monomers and ethylene
glycol dimethacrylate as cross-linker by non-covalent imprinting method. UV-visible spectra
were used to evaluate the interaction strength between the template and the monomers. The composites
of the polymers were calculated from elementary analysis. The porous properties of the
imprinted polymers have been determined from nitrogen adsorption-desorption isotherms. The
imprinting efficiency of the prepared MIPs was evaluated by selective adsorption for luteolin and
its structural analogues. Although the interaction strength of monomers to the template was in the
order 1-ALPP > 4-VP > AA, the binding affinity of the imprinted polymers towards luteolin was in
the order MIP 2 > MIP 3 > MIP 1. Our results demonstrated that the imprinting efficiency was depending
not only on the interaction strength between the template and the monomer, but also on
the fidelity in transferring the complex into the polymer.

Abstract:
According to the study vertical variations of trace elements: Boron(B) and Strontium(Sr) contents testing in clay rock of tertiary Funing Formation(from bottom to up :E1f1、 E1f2、 E1f3、 E1f4), Gaoyou sag, Subei Basin of China., the water of palaeolake in Gaoyou sag of Subei Basin changed from freshwater(E1f1、E1f3) gradually to salt water(E1f2、E1f4). The calcareous cement is formed in early diagenesis. It also means that Gaoyou palaeolake was twice opened to the sea from the first section of Fning Formation to the fourth (E1f1-E1f4). During the second and fourth of Funing Formation (E1f2、E1f4）, the Gaoyou palaeolake was the deepest and the area was largest. Comprehensive analysis of trace elements indicates that palaeo-salinity and depth fluctuated during different sedimentary periods. The sedimentary periods of Funing Formation can be divided into 9 intermediate cycles with relative lake level change. The paleolake level was relative rising quickly in the second and fourth of Funing Formation (E1f4) and relative descending quickly in the first Funing Formation (E1f1). Key words: palaeolake； trace elements； lower tertiary Fning Formation； Gaoyou sag

Abstract:
Objective: To evaluate the effects of Jianpi Qinghua Recipe (JPQHR) on oxygen radicals and transforming growth factor β1 (TGFβ1) in renal tissue in a rat model of chronic renal failure with hyperlipidemia. Methods: Chronic renal failure with hyperlipidemia was induced in rats in untreated group and JPQHR-treated group by 5/6 nephrectomy and high fat diet. Then the rats in these two groups were fed distilled water and JPQHR respectively for eight weeks. The rats in normal control group received no specific interventions. After eight weeks of treatment, the levels of 24 h urine protein (Upr), blood urea nitrogen (BUN) and serum creatinine (Cr), cholesterol (Ch), triglycerides (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) of rats in these three groups were examined. The activity of superoxide dismutase (SOD), contents of malondialdehyde (MDA) and non-esterified fatty acids (NEFA) and expression level of TGFβ1 mRNA in renal tissue of rats in each groups were also determined. Results: The levels of 24 Upr, BUN and serum Cr, Ch, TG and LDL in the JPQHR-treated group were significantly lower than those in the untreated group. The contents of MDA and NEFA and the expression level of TGFβ1 mRNA in the JPQHR-treated group were also significantly lower than those in the untreated group, while the activity of SOD was significantly increased in the JPQHR-treated group as compared with that in the untreated group. Conclusion: The results indicate that JPQHR can improve the renal function of rats with chronic renal failure and hyperlipidemia by regulating lipid metabolism, maintaining balance between prooxidants and antioxidants and reducing expression of TGFβ1 mRNA in renal tissue.

Abstract:
Let ${\mathbf U}(n)$ be the quantum enveloping algebra of ${\frak {gl}}_n$ over $\mathbb Q(v)$, where $v$ is an indeterminate. We will use $q$-Schur algebras to realize the integral form of ${\mathbf U}(n)$. Furthermore we will use this result to realize quantum $\frak{gl}_n$ over $k$, where $k$ is a field containing an l-th primitive root $\varepsilon$ of 1 with $l\geq 1$ odd.

Abstract:
The infinitesimal quantum $\frak{gl}_n$ was realized in \cite[\S 6]{BLM}. We will realize Frobenius--Lusztig Kernels of type $A$ in this paper.

Abstract:
The affine quantum Schur algebra is a certain important infinite dimensional algebra whose representation theory is closely related to that of quantum affine $\frak{gl}_n$. Finite dimensional irreducible modules for the affine quantum Schur algebra ${\mathcal S}_{\vartriangle}(n,r)_{v}$ were classified in \cite{DDF}, where $v\in{\mathbb C}^*$ is not a root of unity. We will classify blocks of the affine quantum Schur algebra ${\mathcal S}_{\vartriangle}(n,r)_{v}$ in this paper.

Abstract:
We will classify finite dimensional irreducible modules for affine quantum Schur algebras at roots of unity and generalize \cite[(6.5f) and (6.5g)]{Gr80} to the affine case in this paper.

Abstract:
Let ${\mathsf F}$ be the Schur functor from the category of finite dimensional ${\mathcal H}_{\vartriangle}(r)_\mathbb C$-modules to the category of finite dimensional ${\mathcal S}_{\vartriangle}(n,r)_{\mathbb{C}}$-modules, where ${\mathcal H}_{\vartriangle}(r)_\mathbb C$ is the extended affine Hecke algebra of type $A$ over ${\mathbb C}$ and ${\mathcal S}_{\vartriangle}(n,r)_{\mathbb{C}}$ is the affine quantum Schur algebras over $\mathbb{C}$. The Drinfeld polynomials associated with ${\mathsf F}(V)$ were determined in \cite[7.6]{CP96} and \cite[4.4.2]{DDF} in the case of $n>r$, where $V$ is an irreducible ${\mathcal H}_{{\vartriangle}}(r)_\mathbb C$-module. We will generalize the result in [loc. cit.] to the case of $n\leq r$. As an application, we will classify finite dimensional irreducible ${\mathcal S}_{\vartriangle}(n,r)_{\mathbb{C}}$-modules, which has been proved in \cite[4.6.8]{DDF} using a different method. Furthermore we will use it to generalize \cite[(6.5f)]{Gr80} to the affine case.

Abstract:
Let ${\boldsymbol{\mathfrak D}_{\vartriangle}}(n)$ be the double Ringel--Hall algebra of the cyclic quiver $\triangle(n)$ and let $\dot{\boldsymbol{\mathfrak D}_{\vartriangle}}(n)$ be the modified quantum affine algebra of ${\boldsymbol{\mathfrak D}_{\vartriangle}}(n)$. We will construct an integral form $\dot{{\mathfrak D}_{\vartriangle}}(n)$ for $\dot{\boldsymbol{\mathfrak D}_{\vartriangle}}(n)$ such that the natural algebra homomorphism from $\dot{{\mathfrak D}_{\vartriangle}}(n)$ to the integral affine quantum Schur algebra is surjective. Furthermore, we will use Hall algebras to construct the integral form ${\mathcal U}_{\mathbb Z}(\hat{\frak{gl}}_n)$ of the universal enveloping algebra ${\mathcal U}(\hat{\frak{gl}}_n)$ of the loop algebra $\hat{\frak{gl}}_n=\frak{gl}_n({\mathbb Q})\otimes\mathbb Q[t,t^{-1}]$, and prove that the natural algebra homomorphism from ${\mathcal U}_\mathbb Z(\hat{\frak{gl}}_n)$ to the affine Schur algebra over $\mathbb Z$ is surjective.
