Forest Land Allocation (FLA), initiated in 1992, aims to protect the forest and develop rural livelihoods. Although this policy has significantly contributed to the gaps between intentions and outcomes regarding forest and land policies in Vietnam, numerous problems and scepticism remain on the benefits for communities, especially ethnic minorities.

This study investigates students’ expectations and experiences of blended learning at Hanoi Open University, Vietnam. In recent years, the Vietnamese government has produced a number of polices advocating the use of ICT in education, including blended learning, aligning this implementation with its goals to modernise. While there has been considerable research around blended learning in higher education in the west, including in the USA, UK and Australia, research in Vietnam is relatively new.

Despite the development of numerous evidence-based interventions (EBIs), many go unused in practice. Hesitations to use existing EBIs may be due to a lack of understanding about EBI components and what it would take to adapt it or implement it as designed. This paper presents EBI Mapping, a systematic approach based on Intervention Mapping, that can be used to understand and clearly describe EBIs, and help planners put them into practice.

: Fluid vents in the Sea of Marmara were discovered and investigated by several studies. In this paper, a numerical model is created for the first time to determine the possible transport mechanism behind those fluid emissions at the seafloor. The finite volume method is used for numerical simulations by implementing a commercial finite volume code, ANSYS-Fluent. The thermal and physical rock properties used in our models are taken from previous studies.

To compare the effect of premedication with 2 different doses of oral paracetamol to prevent pain at propofol intravenous injection. A premedication with oral paracetamol can dose-dependently reduce pain at propofol intravenous injection. To avoid this common uncomfortable concern for the patients, this well-tolerated, available and cheap treatment appears as an option to be implemented in the current practice.

The fluid dynamics of occluded arteries depends on many physiological factors and the resulting complexity of the post-stenotic flow field present a challenge for numerical solvers. The primary goal of this paper is to assess the performance of non-commercial and academic CFD solvers that have not been compared previously, for the purpose of stenosed arterial flow modelling.

Anechoic layer is vital for the underwater acoustic stealth of submarines. This paper develops a simulation-based model for analysis of the acoustic properties of an underwater anechoic layer containing air-filled cavities. First, we present a numerical framework at a relevant scale to implement the acoustical model of an anechoic coating.

In this paper, we discuss a new algorithm to find a non-zero real root of the transcendental equations using series expansion. This proposed method is based on the inverse series expansion, which gives a good approximate root than some other existing methods. The implementation of this algorithm is presented in Matlab and Maple. Sample numerical examples are presented to illustrate and validate the efficiency of the proposed algorithm. The method will help to implement in the commercial package for finding a real root of a given transcendental equation.

In this work our objective is to understand the failure behaviour of unreinforced masonry under in-plane cyclic loading. For this purpose we proposed a plasticity based interface model consists of a single yield surface criteria which is a direct extension of Mohr–Coulomb criteria with a tension cut and compression cap and a back stress vector is introduced as a mixed hardening law variable in the adopted yield surface to capture the unloading/reloading behaviour of masonry under cyclic loading.

This paper introduces an intensive discussion for the dynamical model of the love triangle in both integer and fractional-order domains. Three different types of nonlinearities soft, hard, and mixed between soft and hard, are used in this study. MATLAB numerical simulations for the different three categories are presented. Also, a discussion for how the kind of personalities affects the behavior of chaotic attractors is introduced. This paper suggests some explanations for the complex love relationships depending on the impact of memory (IoM) principle.
