“…The geoheritage sites selection were based on following attributes: phenomenon origin, most visited sites, geographical location (location only within National park/location within Geopark) and significance (scientific, educational or geotouristic). The geodiversity elements, including the high potential for certain types of use, combined with the high degradation risk, demand a higher priority in protection and management policy (Nguyen-Thuy et al, 2018).…”

Geotourism is a relatively new form of tourism with considerable European and global growth potential. Interest in geotourism is developing at a very rapid rate around the world. It is of great importance to support and enhance the global movement about geotourism generally and specifically into geoparks. Geoparks are different to other forms of protected areas, such as national parks, nature reserves etc. In this paper focus of the research is on quantitative assessments of the exceptional values of geoheritage for the science, education and tourism potential use in the area of the potential Geopark Djerdap. Five selected geosites are relevant to evaluate key values for science, education, and tourism with additional consideration given to degradation risk. All the post-assessment findings aim to improve the focus on the ultimate goal of the study, i.e. to justify the synergy between the protection of natural values (geoconservation) and the corresponding activities in the process of managing the development of geotourism in the study area.

“…The study area has been governed by a part of the Mesozoic continental active margin commonly called Da Lat Zone [36]. This is proven by geological evidence consisting of the calc-alkaline magmatic arcs developed during the late Jurassic-late Cretaceous, such as the Deo Ca complexes of I-type granitoids [36][37][38], the Ankoet complex sourced from a mixture of I and S-type granitoid [39], and the Nha Trang extrusive formation (K nt) [36][37][38]40] (Figure 2a). In the Mesozoic and Cenozoic, the study site was affected by two perpendicular normal fault systems of NW-SE and NE-SW strikes [16] and subparallel fault (Figure 2a).…”

“…They were formed by complex geodynamic systems changing over time and depended on tide regime and sediment supplies. Generally, coastal sand dunes and bars are part of the Phan Thiet formation (m b Q 1 2−3 pt) (Figure 2a) from the Pleistocene period originating from marine and marine-eolian depositional sources and the weathering alteration of older bedrocks [38,41]. The sediment sequences are characterized by ridges of sand composed mostly of quartz but bearing some heavy minerals such as ilmenite, zircon, anatase, rutile, pyroxene, and monazite [36].…”

With the growing population and the adverse effects of climate change, the pressure on coastal aquifers is increasing, leading to a larger risk of saltwater intrusion (SI). SI is often complex and difficult to characterize from well data only. In this context, electrical resistivity tomography (ERT) can provide high-resolution qualitative information on the lateral and vertical distribution of salinity. However, the quantitative interpretation of ERT remains difficult because of the uncertainty of petrophysical relationships, the limitations of inversion, and the heterogeneity of aquifers. In this contribution, we propose a methodology for the semiquantitative interpretation of ERT when colocated well data are not available. We first use existing wells to identify freshwater zones and characterize the resistivity response of clayey deposits. Then, we approximate the formation factor from water samples collected in the vicinity of ERT data to derive a resistivity threshold to interpret the saline boundary. We applied the methodology in the shallow aquifers of the Luy River in the Binh Thuan province, Vietnam, where water resources are under pressure due to agricultural, aquacultural, and industrial production. Twenty-one ERT profiles were collected and revealed a much larger intrusion zone, compared to the previous study. Saltwater is present in lowland areas of the left bank over almost the whole thickness of the aquifer, while the right bank is constituted of sand dunes that are filled with freshwater. At a larger distance from the sea, a complex distribution between fresh and saltwater is observed. Our methodology could be applied to other heterogeneous aquifers in the absence of a dense monitoring network.

“…LAMP is also cheaper because it only needs a water bath with a constant heat of 60-65 °C instead of a thermal cycler. The efficiency is especially appealing to developing countries with scarce resources and equipment [19,[69][70][71].…”

Approximately 1.41 million people die annually due to tuberculosis. One of the main problems in Tuberculosis eradication is the development of resistance to various antibiotics. However, current efforts to detect resistances face challenges such as limited equipment, budget, and time. This evidence-based review investigated loop-mediated isothermal amplification, an alternative molecular diagnostic tool with promising performance and applicability in developing countries, and its use combined with Au-Nanoprobe to detect antibiotic resistance in tuberculosis. The literature search was conducted through four databases (Proquest, EBSCOhost, Scopus, and Pubmed) for useful articles on loop-mediated isothermal amplification and Au-Nanoprobe in detecting tuberculosis and tuberculosis resistance. After filtering the result with inclusion and exclusion criteria, the search produced three papers that best answer the clinical question. Loop-mediated isothermal amplification amplifies a target sequence, and Au-Nanoprobe responds to the DNA specific to the target mutant, producing an observable color change. Loop-mediated isothermal amplification and Au-Nanoprobe showed 100% sensitivity and specificity in detecting rifampicin and isoniazid resistance. Another study investigated its viability to detect tuberculosis and found 98.2% sensitivity and 88.2% specificity. Combining loop-mediated isothermal amplification and Au-Nanoprobe had a shorter time to get results and should also be relatively cheaper because it does not need a high temperature to work and requires less equipment. In conclusion, loop-mediated isothermal amplification and Au-Nanoprobe can be used as an efficient and accurate method to detect isoniazid and rifampicin-resistant tuberculosis strains. The new technology is promising for developing countries due to their high disease burden but facing several healthcare barriers.
