Opis:
The application of the supply chain management (SCM) in industry has achieved much success, especially in the manufacturing sector. In the current market, the Vietnamese construction companies must compete not only with domestic companies but also with foreign ones, the application of SCM is essential to improve efficiency and increase their competitive advantage. In this paper, a survey was carried out to identify factors that cause limitation in applying SCM to the Vietnamese construction industry. A qualitative approach was based on prime contractor’s perspective at the construction phase of the project. The survey questionnaire was designed by synthesizing and inheriting the previous studies and consultation with experts. The survey participants are those who have had working experience with main contractors and joined in the construction projects. The face-to-face interviews were conducted to collect data. Descriptive statistics analysis and Exploratory Factor Analysis (EFA) were used to analyze data. The results indicated seven leading causes which limited the application of SCM in the construction industry.

Opis:
The article showed the result of investigation of the length of hydraulic jump in trapezoidal channel. In this study, the basic factors that affect the length (Lj) and roller length (Lr) of hydraulic jump were investigated by physical trapezoidal channel’s model. The experiment carried out in purpose to establish a new empirical equation for calculating the roller length (Lr) of the jump in the horizontal trapezoidal channel with the upstream flow Froude number 4.0 to 9.0 (the steady jump). The hydraulic characteristics of forced jump were measured and statistically calculated by excel software. The results of data analysis showed that the MAPE was relatively small (< 5%), and R2 > 0.9 (strong correlation between predicted and observed values) and other statistical indicators are less than 0.1 (MSE = 0.004, RMSE = 0.062 và MEA = 0.047). Therefore, the equation found could be appropriated and applied to calculate characteristics of hydraulic jump trapezoidal channel.

Opis:
The proposal of a system for the safe recovery of unexploded ordnance (UXO), chemical weapons (CW) and chemical warfare agents (CWA) dumped at sea mainly after WWI and WWII is described in this work. The proposed solution addresses the tasks required to neutralise thousands of tons of dumped material and the currently available solutions and proposed ideas. Requirements concerning the features of a recovery system are defined and scrutinised, these being intended to ensure the safety of this phase of the UXO/CW neutralisation process. To meet this requirement, the concept of a remotely operated, two-component working size underwater vehicle is proposed, supplemented by a properly sized and outfitted surface platform that is an important part of the recovery system. Finally, the basic components of the proposed system configuration are characterised, together with their functions during the recovery of dangerous CWA-related objects.

Opis:
Large rock mass deformation around deep roadways in the weak rocks was a significant problem in mining activities in Vietnam and other countries. The excavation of roadways leads to high releasing stress, which exceeds the peak strength of spalling surrounding rock and causes it to enter the post-failure stage. Tensile failures then initiate and develop around the roadways, which causes the fragmentation, dilation, and separation of surrounding rock. The capacity of the primary support system is low, which results in a severe contraction in the whole section of roadways, which requires finding solutions to prevent the deformation of rock mass around roadways and technical solutions from stabilizing for deep roadways. To stability analysis of roadways can be applied analytical, experimental, semi-experimental, and numerical methods. This paper introduces the prevention mechanism of large deformation of rock mass around roadways using 2-level rock bolts. The research results show that using the system of two-level rock bolts can reduce the values of tensile stress on the boundary of roadways range from 10 to 15% compared with only one. The importance of the total displacement of rock mass on the boundary of roadways will be reduced from 3.47 to 13.85% using six long cable bolts.
