State Regulation of Forest Industrial Complex in Vietnam

This article discusses the development of the forest industrial complex - one of the key sectors of the economy of the Socialist Republic of Vietnam which, to a great extent, defines the status and outlook of the Vietnamese economy in general. Development of the forest industrial complex is discussed in the context of fundamental socioeconomic reforms being implemented in Vietnam. Among other things they are aimed to attain one of the key backbone goals, i.e. defining the optimum balance between the state regulation and the initiative of economic subjects. The author touches endogenic and endogenic factors of the Vietnamese forest industrial complex development, including the natural-and-geographic factor, ethno-cultural traditions in economic activities, attraction of foreign investments. The author emphasizes both the achievements in the process of reforming the Vietnamese economy and unattained goals

Influence on the World Market on the Features of Development of Forestry Complex of the Asia-Pacific Region

The estimation of the development of the main trends of the global timber marketisgiven,there are characterized relative labor productivity indices in the forestry sector of the world economy in various regions of the world over 20 year. There is carried an analysis of the key implications of the spread of the modern model of consumption in the Asia-Pacific region for the wood and furniture industry

Soft Robotic Link with Controllable Transparency for Vision-based Tactile and Proximity Sensing

Robots have been brought to work close to humans in many scenarios. For coexistence and collaboration, robots should be safe and pleasant for humans to interact with. To this end, the robots could be both physically soft with multimodal sensing/perception, so that the robots could have better awareness of the surrounding environment, as well as to respond properly to humans' action/intention. This paper introduces a novel soft robotic link, named ProTac, that possesses multiple sensing modes: tactile and proximity sensing, based on computer vision and a functional material. These modalities come from a layered structure of a soft transparent silicon skin, a polymer dispersed liquid crystal (PDLC) film, and reflective markers. Here, the PDLC film can switch actively between the opaque and the transparent state, from which the tactile sensing and proximity sensing can be obtained by using cameras solely built inside the ProTac link. In this paper, inference algorithms for tactile proximity perception are introduced. Evaluation results of two sensing modalities demonstrated that, with a simple activation strategy, ProTac link could effectively perceive useful information from both approaching and in-contact obstacles. The proposed sensing device is expected to bring in ultimate solutions for design of robots with softness, whole-body and multimodal sensing, and safety control strategies.Comment: Submitted to RoboSoft 2023 for review.

On a viscoelastic heat equation with logarithmic nonlinearity

This work deals with the following viscoelastic heat equations with logarithmic nonlinearity ut − ∆u + Z t 0 g(t − s)∆u(s)ds = |u| p−2u ln |u|. In this paper, we show the effects of the viscoelastic term and the logarithmic nonlinearity to the asymptotic behavior of weak solutions. Our results extend the results of Peng and Zhou [Appl. Anal. 100(2021), 2804–2824] and Messaoudi [Progr. Nonlinear Differential Equations Appl. 64(2005), 351–356.]

SYNTHESIS OF STARCH MODIFIED MONTMORILLONITE AS AN EFFECTIVE ADSORBENT FOR Pb (II) REMOVAL FROM WATER

The adsorbent is prepared by the montmorillonite co-modification with starch for the removal of Pb (II) ions from aqueous solution. The Fourier-transformed infrared (FTIR), X-ray diffraction (XRD) spectroscopies were used to determine the structure and characteristics of the adsorbent. The main factors affecting the removal of Pb (II) ions were investigated, including the effect of pH, contact time, adsorbent dosage and the initial concentration of Pb (II). Batch process can be used for adsorption and equilibrium studies. The experimental data were fitted using Freundlich and Langmuir adsorption models. The Langmuir isotherm best fitted the experimental data with R2 0.99 and maximum Pb (II) adsorption capacity of 21.5 mg/g indicated monolayer adsorption. Kinetic studies using pseudo-first-order and pseudo-second-order rate models showed that the process complied well with the pseudo second-order rate model

ANY LINKS BETWEEN ECONOMIC PERFORMANCE AND INSTITUTIONAL QUALITY? EVIDENCE FROM VIETNAM PROVINCES AND CITIES

This study aims at finding possible links between the economic performance and institutional quality of provinces and cities in Vietnam by using regression analysis. The economic performance is measured by Net revenue of all firms in each province or city. The institutional quality is representative with Provincial Competitiveness Index (PCI) of respective province or city. For regression models, while the dependent variable is economic performance of provinces, PCI is used as the key independent variable. Labor and capital are main production factors of the economic performance, so they are also included in the regression models. The data of the years 2012 and 2013 collected from sixty-three provinces and cities in Vietnam is used in the study. The study shows a link between the economic performance and the institutional quality of provinces and cities in Vietnam

Polyamorphism and Two State Model in Liquid GeO2_{2} under Compression: Insight from Visualization of Molecular Dynamics Data

The polyamorphism and two-state model based on the coordination number distribution in liquid GeO$_{2}$ at 3200~K and in a wide pressure range are investigated by molecular dynamics simulation. Results show that the structure of liquid GeO$_{2}$ mainly consists of GeO$_{x}$ coordination units $(x=4,5,6)$ and OGe$_{y}$ linkages $(y=2, 3)$. The distribution of OGe$_{y}$ linkages in network structure is not uniform but tends to form clusters of OGe$_{y}$. The cluster of OGe$_{2}$ will form low-density phase region, conversely the cluster of OGe$_{3}$ will form high-density phase region. In other word, under compression, in the liquid GeO$_{2}$ coexist two states: low-density and high-density. The size of phase regions significantly depends on compression
