CO2 flux measurements in volcanic areas using the dynamic concentration method: the influence of the soil permeability.
2006
In order to evaluate the influence of soil permeability on soil CO2 flux measurements performed with the dynamic concentration method, several tests were carried out using soils characterized by different permeability values and flow rates. A special device was assembled in the laboratory to create a one-dimensional gas flow through a soil of known permeability. Using the advective-diffusion theory, a physical model to predict soil concentration gradients was also developed. The calculated values of CO2 concentrations at different depths were compared with those measured during the tests and a good agreement was found. Four soils with different gas permeability (3.6 x 10(-2) to 1.23 x 10(2)…
Awareness of second language inflectional morphology: A case study on Finnish as a second language
2007
The Finnish language has a very extensive inflectional morphology, whereas Vietnamese, as an isolating language, has no inflection at all. Therefore, the major challenge encountered by Vietnamese immigrants learning Finnish is to develop awareness of the existence, function and use of inflection. This paper examines how this process manifests itself in native-non-native speaker (NS-NNS) conversations during the initial stages of second language acquisition. All the negotiation sequences including overt signals of problems in understanding were subjected to a closer analysis, and the linguistic modifications performed to solve the problems were analysed on the level of both interaction and g…
Tra dottrina grammaticale e ortografia latina: l’Aldina del De Aetna di Pietro Bembo
2016
Diacritical marks introduced by Pietro Bembo with the help of his editor, Aldus Manutius, in the first edition of his dialogue De Aetna form a complex and well-structured system. Although devised for practical purposes, so as to ensure a correct reading and phrasing of the Latin text, this system is clearly based on solid theoretical premises. The decisive factor for its introduction was the experience of editing Greek texts, which became the impulse as well as the basis for the system of diacritical signs. The influence of Latin grammarians (in particular, Servius and Priscianus), who had applied Greek accent theory to Latin language, also played an important part. Within a system essentia…

Identification of enteroviral infection among infants and children admitted to hospital with acute gastroentritis in Ho Chi Minh City, Vietnam
2005
A total of 276 fecal specimens collected from infants and children admitted to hospital with acute gastroenteritis in Ho Chi Minh City, Vietnam from October 2002 to September 2003, were tested for the presence of enteroviruses by RT-PCR and virus isolation. Enteroviruses were detected in 27 patients by RT-PCR corresponding to 9.8%. However, only four enterovirus strains could be isolated by cell culture with two different cell lines CaCo2 and Vero, showing specific cytopathic effect (CPE). The results clearly indicate that RT-PCR is a sensitive, specific assay to investigate the true burden of acute gastroenteritis due to enteroviruses in clinical fecal specimens. In the present study, ente…
Early Postnatal and Preschool-Age Infection by Fasciola spp.: Report of Five Cases from Vietnam and Worldwide Review
2020
Fascioliasis is reported in five Vietnamese children aged 4 years or younger. A 10-month-old girl child and a 12-month-old boy child are the youngest patients ever diagnosed. Eggs in stools suggested an infection occurred at 5-6 months and 7-8 months of age, respectively. DNA sequencing and egg size indicated this to be the first report of a verified Fasciola gigantica infection in so small children. No specific diagnosis could be obtained in two 3-year-old children detected in the acute phase. A big and gravid ectopic F. gigantica-like worm was surgically found in a 4-year-old boy presenting with peritonitis. A worldwide review showed only 38 past cases in preschool children. They included…
Strongyloidiasis in northern Vietnam: epidemiology, clinical characteristics and molecular diagnosis of the causal agent.
2019
Abstract Background Strongyloidiasis is a health problem in Vietnam, but appropriate information is still limited. The aim of this study was to determine the prevalence, geographical distribution, epidemiological aspects, symptoms and other health indicators of Strongyloides stercoralis infections in patients from 27 provinces of northern Vietnam attending the Hanoi Medical University Hospital during 2016 and 2017. Methods Blood samples of 2000 patients were analyzed for S. stercoralis infection with an IgG ELISA test. Seroprevalence was analyzed by gender, age group, locality of origin (rural or urban areas) and symptoms. Stools from the seropositive patients were examined for the detectio…

Fast determination of fish mineral profile. Application to Vietnamese panga fish
2013
A methodology, based on inductively coupled plasma optical emission spectrometry after microwave-assisted digestion with HNO3/H2O2, was developed to determine the mineral profile of panga fish samples imported from Vietnam. A total of 42 essential and toxic elements were studied in seven samples taken from the local market. Preliminary studies were focused on selecting the best wavelength and the required dilution of samples in order to provide the highest sensitivity to maximize the number of analytes to be determined without spectral or matrix interferences. Adequate accuracy was assured by the analysis of certified reference material TORT-2. Mercury was also determined by a direct method…
Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sici…
2014
Ethnopharmacological relevance: This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It specifies contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. Aim of the study: The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of…
