漳腊淘金记:民国时期川西北的财富、生计与冒险

漳腊金矿的兴办是权力与资本交互影响的结果。民国初年,各路军阀先后主导着漳腊矿权,竞相逐利。防区制终结后,漳腊金矿改由四川省政府经营。随着全面抗战的爆发,国民政府加强了对四川资源的调控,国家资本介入漳腊金矿。槽户制是漳腊金矿的基本组织形式,漳腊私人采金的发达与该制度有密切关系,槽户制的盛行导致政府统制黄金生产、流通的目标难以达成。漳腊金矿的收益主要归军阀、资本家、官僚豪绅、金商等势力所有,多数金夫子并未实现财富梦想。金矿业催生了金河坝市场的畸形繁荣,促进了漳腊与内地的交往交流。同时,漳腊矿区的诸多乱象,也反映了矿区社会与当地民众之间存在着张力。

Galerkin solution of Winkler foundation-based irregular Kirchhoff plate model and its application in crown pillar optimization

Irregular plates are very common structures in engineering,such as ore structures in mining.In this work,the Galerkin solution to the problem of a Kirchhoff plate lying on the Winkler foundation with two edges simply supported and the other two clamped supported is derived.Coordinate transformation technique is used during the solving process so that the solution is suitable to irregular shaped plates.The mechanical model and the solution proposed are then used to model the crown pillars between two adjacent levels in Sanshandao gold mine,which uses backfill method for mining operation.After that,an objective function,which takes security,economic profits and filling effect into consideration,is built to evaluate design proposals.Thickness optimizations for crown pillars are finally conducted in both conditions that the vertical stiffness of the foundation is known and unknown.The procedure presented in the work provides the guidance in thickness designing of complex shaped crown pillars and the preparation of backfill materials,thus to achieve the best balance between security and profits.

Effect of Schiff base as corrosion inhibitor on AZ31 magnesium alloy in hydrochloric acid solution

Schiff base derived from the condensation reaction of analar grade 1-amino-2-naphthol 4-sulphonic acid with cinnamaldehyde was prepared under microwave condition.The Schiff base was analysed by infrared spectroscopy.This Schiff base as a corrosion inhibitor of AZ31 magnesium alloy in 0.05 mol/L HCl solution was studied.The inhibition effect of the Schifif base compound（4Z）-4-（3-phenyl allylidene amino）-3-hydroxy naphthalene-1-sulfonic acid（AC） on AZ31 magnesium alloy corrosion was studied using mass loss,potentiodynamic polarization technique,electrochemical impedance spectroscopy methods.The potentiodynamic polarization curve shows that Schiff base AC inhibits both anodic and cathodic reactions at all concentration,which indicates it is a mixed type inhibitor.EIS results indicate that as the additive concentration is increased,the polarization resistance increases whereas double-layer capacitance decreases.The adsorption of AC on the AZ31 magnesium alloy surface in 0.05 mol/L HCl obeys the Langmuir adsorption isotherm.

In vitro degradation resistance of glucose and L-cysteine-bioinspired Schiff-base anodic Ca−P coating on AZ31 magnesium alloy

A Schiff base(a compound containing a C=N bond)induced anodic Ca−P coating was prepared on AZ31 Mg alloy in a mixed solution of CaCl_(2) and KH_(2)PO_(4) at 60℃ in the presence of glucose and L-cysteine.The microstructure and chemical composition of the coatings were characterized using FE-SEM,FT-IR,XRD,and XPS.The in vitro degradation resistance of the coated samples was evaluated via potentiodynamic polarization(PDP),electrochemical impedance spectroscopy(EIS),and hydrogen evolution test.The experimental results show that the Ca−PSchiff base coating is composed of CaHPO_(4)(DCPA)and hydroxyapatite(HA),whereas HA is not present in the Ca−P coating.The Ca−P_(Schiff base) coating thickness is about 2 times that of Ca−P coating(Ca−P coating:(9.13±4.20)μm and Ca−P_(Schiff base):(18.13±5.78)μm).The corrosion current density of the Ca−P_(Schiff base) coating is two orders of magnitude lower than that of the Ca−P coating.The formation mechanism of the Ca−P_(Schiff base) is proposed.

An Empirical Research of Ethical Banking in Turkey

Ethical banks can be defined as financial institutions providing both social and economic profitability for the society and environment. Placement of assets and avoiding social exclusion are significant factors that differentiate ethical banks and the rest of financial intermediaries. Ethical banking is a new concept in Turkey. This paper analyzes the situation of ethical banking by examining the significant differences in lending behaviors of 49 Turkish banks in terms of their functions and ownership structures. We conducted non-parametric tests of Kruskal Wallis, Jonckheere-Terpstra, Mann-Whitney, Kolmogorov-Smirnov and Wald-Wolfowitz. We found that in terms of ownership structure, state-owned banks are more ethical than private banks when the placement of assets and avoiding social exclusion factors are considered. In terms of function, participation banks locate their funds to social value generating sectors more ethically than deposit and development banks. From the avoiding exclusion aspect, deposit banks are more ethical than other functional banking groups （i.e., participation and development banks）.

Schiff Base Derived from p-Nitrobenzaldehyde and1,8-Naphthalenediamine Precursor in Metal Ions Uptake

The characteristic coordination behavior of Schiff bases synthesized from carbonyl been investigated and studied in different field, such as their chemistry and biological activity and primary amine compounds have Few numbers of Schiff bases were implicated in analytical aspect such as metal uptake techniques. The Schiff base and may its chelates derived from p-nitrobenzaldehyde and 1,8-naphthalenediamine were synthesized and characterized by different analytical tools. The chemical structures have been elucidated by physiochemical methods. The site of the coordination with metal ion gave this Schiff base the advantage to be used in uptake techniques, either as batch or column. The uptake studies preformed and analyzed with respect to justification of the site of coordination.

A proposed direct measurement of cross section at Gamow window for key reaction 19F(p,α) 16O in Asymptotic Giant Branch stars with a planned accelerator in CJPL

In 2014, the National Natural Science Foundation of China （NSFC） approved the Jinping Underground Nuclear Astrophysics laboratory （JUNA） project, which aims at direct cross-section measurements of four key stellar nuclear reactions right down to the Gamow windows. In order to solve the observed fluorine overabundances in Asymptotic Giant Branch （AGB） stars, measuring the key 19F（p,a）16O reaction at effective burning energies （i.e., at Gamow window） is established as one of the scientific research sub-projects. The present paper describes this sub-project in details, including motivation, status, experimental setup, yield and background estimation, aboveground test, as well as other relevant reactions.

Initial Boundary Value Problem of an Equation from Mathematical Finance

Consider the initial boundary value problem of the strong degenerate parabolic equation ?_(xx)u + u?_yu-?_tu = f(x, y, t, u),(x, y, t) ∈ Q_T = Ω×(0, T)with a homogeneous boundary condition. By introducing a new kind of entropy solution, according to Oleinik rules, the partial boundary condition is given to assure the well-posedness of the problem. By the parabolic regularization method, the uniform estimate of the gradient is obtained, and by using Kolmogoroff 's theorem, the solvability of the equation is obtained in BV(Q_T) sense. The stability of the solutions is obtained by Kruzkov's double variables method.
