This study aims to collect and systematically document the traditional knowledge of poisonous plants by interviewing Van Kieu and Pa Ko ethnic communities in Quang Tri province. A total of 56 poisonous plant species (27 herbs, 15 shrubs and 14 woody plants) of flowering plants belonging to 26 families and 50 genera were found in the study site. Based on the Recorded Poisonous Plant Proportion (RPPP) values, 25 commonly recorded poisonous plants were selected for analyzing Fidelity Level (FL) and Informants Consensus Factor (ICF).

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .

Forest fires present a significant threat to the tropical forest ecosystem in the northwestern region of Vietnam. Our study aimed to assess the impacts of environmental factors on forest fire occurrence and to map forest fire probability for the whole region. The forest fire occurrence data over the period 2003–2016, environmental factors (climate, fuel condition, topography, and human activity), and the MaxEnt approach were used for this study.

The electronic states of FeSin −/0/+ (n = 1-2) clusters have been investigated with DFT, CASPT2, and DMRGCASPT2 methods. By using relatively large active spaces, the DMRG-CASPT2 method is found to provide highly accurate relative energies for the various relevant electronic states. Leading configurations, bond distances, harmonic vibrational frequencies, and relative energies for the low-lying states of the title clusters are reported.

n this work, the main aim is to map the potential zones of groundwater in Central Highlands (Vietnam) using a novel ensemble machine learning model, namely CG-LMT, which is a combination of two advanced techniques, namely Cascade Generalization (CG) and Logistics Model Trees (LMT). For this, a total of 501 wells data and a set of twelve affecting factors were gathered and selected to generate training and testing datasets used for building and validating the model.

This article presents computational insights into the geometric and electronic structures of NbSi4 −/0 clusters using density functional theory and the CASSCF/CASPT2 method. The anionic and neutral ground states are identified as the 1A′ and 2A′ states, respectively, within a trigonal bipyramidal isomer where the Nb atom occupies the equatorial position. The adiabatic detachment energy for the transition from the anionic ground state 1A′ to the neutral ground state 2A′ is estimated to be 2.30 eV.

Supply chain management literature suggests that there are many mutually dependent points in the supply chain and each supply chain point is sensitive to the performance of one another. In the course of business, interrelated supply chain activities might get destabilized because of the manmade or natural factors.

The research found that most foreign workers are of unskilled labor with less pay and longer working hours, and this justifies their recruitment, which means that local workers with skilled skills are more affected by the increasing numbers of foreign workers. Therefore, it is necessary to protect national workers against foreign labor competition. In the labor market through the establishment of strict laws protect the local factor and restrict the work of foreign workers and contribute to the stability of wage rates

This paper contributes to the literature on the internationalization process of new ICT companies, especially the ride-hailing developer firms. It analyzes the global expansion of UBER in the Asian market. UBER did an aggressive expansion using a standard business model in every market that they get into. The strategy was on scale economy rather than localization of services. The case analysis suggests that UBER was unsuccessful in its global expansion due to a number of factors especially t

Manufacturing organizations spend lot of money and time to implement ERP thinking that after implementation, it will lead to increase in work efficiency. However, in most cases, ERP implementation results in a high failure rate. Most research has focused on the critical success factors (CSF) for ERP implementation, whereas factors such as success measures, benefits of ERP and the factors responsible for successful implementation in Indian manufacturing sectors has been discussed by very few researcher.

The results of the research showed that paying attention to employees' motivational factors and their needs and paying attention to individual differences of each employee is one of the most important factors. Which can be achieved in the productivity of human resources and one of the essential conditions for achieving the goal in every way is to provoke and motivate and respond to the people who do it. Factors like meritocracy, awarding rewards to better services, preventing and disrupting individual choices are one of the most important motivations and responses.
