Increasing levels of greenhouse gases lead to ocean warming, which affects a range of marine organisms. Corals live in a narrow temperature range and become stressed when the temperatures change. Bleaching occurs when the temperature exceeds the coral’s threshold, and can be severe when this is combined with other stressors such as light. In order...

The article aimed to assess the net ecosystem metabolism (NEM), and photosynthesis performance of Pocillopora acuta coral on the reef flat and reef slope of the southeast fringing reef of Phuket, Thailand, from June 2017 to January 2018, using 30 x 45-cm benthic oxygen flux chambers and a Junior Pulse Amplitude Modulated fluorometer. The results sh...

The materials that are developed from the different kind of marine organisms have a broad range of properties and characteristics that can explain their potential functions in the biomedical area. Accordingly, new opportunities are created by biomaterials produced from marine-based sources such as calcium phosphate-based bioceramics, composites, an...

Protected areas, nature reserves and national parks in Vietnam, has considered foot patrols under traditional law enforcement with local forest guard (LFG). The participant between LFG and rangers in protected areas has been applied as commons way of patrolling on forest protection. However, very few studies have considered the contribution of LFG...

Law enforcement efforts related to patrol routes may be sufficiently supporting forest protection around the world. However, the adequacy of patrol efforts of stable patrol routes, with regard to illegal activities on conservation at the local level, has infrequently been explored in the past time. This study is to compare the highest qualification...

Effective management of the special-use forests in Vietnam, e.g. nature reserves and national parks, depends on information about disturbances of illegal activities due to the effective protection as patrol ranger efforts (PREs). Patrol rangers are indispensable for protecting forest in conservation areas. Moreover, to enhance PREs efficiency is re...

Calcium phosphate materials can be produced using a number of wet methods that are based on hydrothermal or co-precipitation methods that might use acidic or basic chemical environments. In our previously published works, we have investigated calcium phosphates such as monetite, hydroxyapatite, and whitlockite which were successfully produced by me...
