Thumb hypoplasia, a congenital malformation characterized by an underdeveloped or absent thumb, presents significant functional and aesthetic challenges. In Vietnam, low-middle income developing country, the management of thumb hypoplasia is shaped limited resources, geographic disparities, reliance on international collaborations. This article reviews current state diagnosis, surgical treatment, rehabilitation in with focus unique challenges faced healthcare providers resource-constrained...

Vibrio natriegens has recently been identified as a promising host for the biotechnology industry thanks to its inherent qualities, which include fast growth rate, non-pathogenicity humans, and versatility in using substrates. These advantages have led potential use of V. biosynthesis several products. Basically, industrial scale requires fermentation or cultivation processes be conducted at high substrate biomass concentrations maximize final retrieved product. However, studies on cell...

Chitin from crustacean waste can be the future substrate for bioindustry towards circular economy concept, especially countries having large production of sea products like Vietnam. However, chemical conversion chitin into monomers implies high amounts NaCl in a mixture with glucosamine, N-acetyl and acetate. Thus, bacterial strain that tolerate salt concentration, use as sole carbon source such Vibrio natriegens holds great potential producing bioproducts derivatives. In this study, V....

This study aimed to evaluate the adaptive capacity (AC) saltwater intrusion (SI) in Dong Nai province up 2030 via 20 indicators. The research scope included 57 wards Bien Hoa city, Long Thanh, and Nhon Trach districts where have been facing SI. Results showed that 2014, nearly 90 % of investigated AC indices range medium-low level, distributed (30), Thanh (15), (6). Forecasts 2020 2030, local are increased: mentioned number is gone down about 88 60 respectively. Indicators need taken into...

Saltwater intrusion, which is a natural process, strongly influenced by climate change, and almost negatively affects the lives livelihoods of communities. This work aims at assessing changes in saltwater intrusion main rivers located Dong Nai province. The results indicated that Long Thanh Nhon Trach districts have been affected with highest salinity concentrations about 26-28 ‰. level during dry season higher than rainy one boundaries 1 ‰ 4 gradually extend towards inland water. Besides,...

This study aims at assessing changes in the surface water quality Dong Nai province (2010- 2014). In addtion, pollutant loads of wastewater sources were calculated till 2020–2030 with 03 treatment scenarios serving for local environmental management. The index (WQI) showed Province to be gradually improved during dry season but significantly declined rainy last 5 years due high concentrations suspended solids (SS), Fe and microorganism - especially 3rd segment river through Bien Hoa City....

Saltwater intrusion (SI) associated with El Nino phenomenon is a particularly concerned issue in period of 2015–2016. Salinity evolutions the Mekong Delta and Vinh Long province are becoming serious. Therefore, this work aimed at assessing changes saltwater during recent ten years (2007–2016), including highest, lowest, average salinities. Besides, 19 surface water samples were collected analyzed to evaluate current status salinization 2016. Results showed that salinity tends propagate into...

Climate change (CC) and their related impacts become clearer significantly affect socio-economic fields as well public health. Accordingly, the assessment of vulnerability to CC becomes necessary is basis for formulation measures enhance adaptive capacity mitigate effects. This work aims review situation research vulnerability; especially approaches methods, serving establishing methodology due concerned industries, sectors, areas, objects.

This work aimed at assessing the sensitivity to saltwater intrusion (S) in Dong Nai province 2030. Thereby, investigated areas consisted of 57 wards Bien Hoa city, Long Thanh, and Nhon Trach districts – which are exposed intrusion. In 2014, index (SI) city was lowest (S=26.46). The wards’ SI were range low medium-low (SI = 12.38–26.46). next is Thanh district (SI=44.64). medium-high level 32.22–55.08). most sensitive area (SI=49.44), fluctuating 33.72–58.47). To 2020 2030, tends decrease (in...

95% of the causes climate change (CC), according to Intergovernmental Panel on Climate Change (IPCC), are rooted from human activities. Raising community awareness is, thus, primary solution issue. This research aims develop communication programs raise public CC, a case study in Thuan An District. The context, object properties, information gaps, and demand, etc. have been surveyed documented. Thereby, CC were proposed, including: objectives, messages, media, compatible activities,...

Effects of temperature (T) rise in conditions isothermal, adiabatic sonication -US (the same power input -PUS), and sole thermal hydrolysis, then its effects associated with PUS for the specific energy (ES) treatment duration were investigated. The main results that evolution sludge T depended on PUS. In cases ES (different different US duration), small probe, high still beneficial disintegration. However, big a low disintegration efficiency was achieved at due to which leads significant...

To improve the fibrinolytic enzyme production of mutant strain Bacillus sp. ES4, response surface methodology was used to optimize medium composition. Thirty-four flask scale experiments were carried out, and results fitted quadratic models using Design-Expert software. The ANOVA analysis revealed that components differently affect cell density production. At optimal condition for production, enzymatic activity attained 686 ± 43 FU/mL, which is increased by 1.7-fold compared initial (404 4...

Cai Nuoc shows the area for shrimp hatching of 31,626 ha (99.4%), third largest in output whole province. There are 11 sites collecting samples from 3 patterns: traditional extensive hatching, improved and industrial February, April, May, June July 2010. The analysis 18 standards reflects actual state pond environment. possible conclusions about pollutant loads emerging are: Shrimp pattern causes load; some pollutants 2009 2010, respectively, SS – 149,512 tons và 143,212 tons, BOD5 6,896...

Survey results in 72 mechanical manufactures Ho Chi Minh City, conjunction with related studies show that the charge of industrial solid waste – hazardous treatment is operated two forms: fixed or progressive based on generated volume. Price collection - transportation storage landfill for each composition widely varying (5-20 times), depending agreement between production facilities and service units. not yet able to handle relationship technology, level be achieved as well correlation...
