Abstract

Purpose

In this work, a kind of Mannich base (C21H25NO) was synthesized with cinnamal aldehyde, acetophenone and diethylamine in a condensing reflux device based on the conventional method. Optimization of the inhibitor concentration was explored.

Design/methodology/approach

Spectral properties of this compound was investigated by FTIR, and its inhibition efficiency and mechanism on N80 steel in 20% hydrochloric acid solution were studied by weight loss measurement, electrochemical measurement (potentiodynamic polarization and electrochemical impedance spectroscopy) and surface analytical measurement (scanning electron microscope with energy dispersive spectrometer).

Findings

The results showed that the new inhibitor reduced the double-layer capacitance and increased the charge transfer resistance. The inhibition efficiency is 99.7% when the concentration of C21H25NO is 3%. The adsorption of C21H25NO on N80 steel surface in 20% HCl solution was found to be spontaneous and steady. Observed from the steel surface, an inhibition film was confirmed to be presented after adding inhibitor and successfully hindered the corrosive ions from reaching the bulk steel.

Originality/value

A new Mannich base (C21H25NO) was synthesized by cinnamal aldehyde, acetophenone and diethylamine for the corrosion prevention of N80 steel in 20% hydrochloric acid solution.

Abstract

Purpose

The purpose of this paper is to investigate the mechanical behavior and propagation of cracks of numerical granite samples through the Brazilian split test and to provide a reference for predicting the behavior of real granite samples.

Design/methodology/approach

The numerical models of granite containing two fissures are established using the parallel bond model (PBM) and the smooth joint model (SJM) in PFC2D. The peak stresses, number of cracks and anisotropic ratios are obtained to study the influence of the mineral composition and the angle of inclination of rock bridge on the strength, failure mode and deformation characteristics.

Findings

The numerical results obtained show that the mineral composition has a marginal influence on the peak stress. When the angle of inclination of rock bridge β increases, the peak stress drops to its minimum value at β = 90° and then gradually increases to a relatively low level. The behavior of cracks falls into three categories based on the distribution of cracks. By analyzing the stress–strain curve and the process of crack propagation for sample No. 4 with β = 60°, it is found that the process of failure can be divided into four stages and tensile cracks dominate. The anisotropic ratios of peak stress and a number of cracks obtained show that the peak stress is low anisotropic and the number of cracks is medium anisotropic.

Originality/value

This paper presents a numerical simulation method to analyze mechanical behavior and propagation of cracks under different conditions. The proposed method and the results obtained are useful for predicting the behavior of real granite samples in laboratory and engineering projects.

Abstract

Purpose

The purpose of this paper is to examine the role and importance of trust in a type of Chinese farmer cooperative organization called “Farm Bases” (FBs), considering the extent to which trust affects their performance and how the relationship between trust and FB performance is affected by perceptions of risk and uncertainty and other considerations.

Design/methodology/approach

The authors interviewed a random sample of 355 farmers, most of whom are from 42 different FBs in China. The authors operationalized organizational trust by assessing the perception of trustworthiness and competence that farmers have in FB managers. The authors conducted a regression analysis of the data to answer the research questions.

Findings

The findings support a nuanced role of trust for performance measures of FBs. Trust matters but in limited and specific contexts. Specifically, trust does not correlate with the marketing volume of Chinese FBs and only weakly correlates with FB compliance of production standards.

Originality/value

FBs play an essential role in China’s agribusiness policies and are pervasive in Chinese business practices. Very little research has been conducted on Chinese FBs and of the role of trust in organizational performance.

Abstract

Purpose

Analyze the importance of sustainable innovation strategy applied in manufacturing companies in Indonesia which affects the company's financial performance through several mediating variables.

Design/methodology/approach

The population in this research was medium and large manufacturing company business units in East Java. Business units are part of a company considered as the profit center. The business unit as the unit of analysis in this research is part of the organization that: (1) is responsible for the production and marketing of a product or set of products; (2) is formed by product type; (3) has its own competitors which are different from competitors of other business units or divisions within a parent company; (4) has a manager who is responsible and has authority over the planning and implementation of strategies to achieve the specified profit target.

Findings

Innovation strategy has a significant effect on financial performance. Human capital does not significantly mediate the relationship between innovation strategy and financial performance. Capital performance and internal performance do not mediate the relationship between innovation strategy and financial performance. Management accounting information system does not mediate the relationship between innovation strategy and financial performance. Internal process performance mediates the relationship between innovation strategy and financial performance. Management accounting information system and internal process performance mediate the relationship between innovation strategy and financial performance.

Originality/value

The difference in findings confirms that this research needs to be conducted. On the other hand, there is no research that has comprehensively tested the mediating effects of Human Capital and Management Accounting Information System in the relationship between Innovation Strategy and Internal Process Performance and the Impact on Corporate Financial Performance. The originality of this research can be seen in the use of contingency theory which narrows the gap between the industrial organization (I/O) paradigm and the resource-based view (RBV) regarding competitive advantage and performance. Specifically, this research introduces innovation strategy, human capital, management accounting information system, and internal business process performance as the contingency factors that affect financial performance. Second, empirically, this research tries to reduce the gap in empirical research by offering new research model and new research establishment at the level of strategic business units (SBU) in manufacturing companies in East Java. This research is expected to be useful for policy decision making, especially for managers who want to improve strategic business unit's financial performance.
