Determination of protease and chitinase activities from Paecilomyces variotii NV01 isolated from Dak Lak pepper soil
Vietnam Journal of Science, Technology and Engineering - Tập 61 Số 4 - Trang 58-63 - 2019
Chu Thanh Binh, Tran Van Tuan, Tran Bao Tram, Bui Thi Viet Ha
The filamentous fungus Paecilomyces is currently being developed as a biocontrol agent against plant parasitic nematodes, which often cause black leaf disease in pepper and coffee trees. Nematode eggs and cuticles are the infection sites for biocontrol agents that penetrate those areas by the production of lytic enzymes. Paecilomyces variotii NV01 was isolated from pepper soil from the Dak Lak pro...... hiện toàn bộ

Expression of several deubiquitinase and tyrosine phosphatase genes involved in inflammatory response in lymphoma
Vietnam Journal of Science, Technology and Engineering - Tập 66 Số 1 - Trang 90-95 - 2024
Nguyen Hoang Giang, Nguyen Trong Ha, Nguyen Thi Xuan
Lymphoma represents a heterogeneous group of cancers affecting the lymphatic system, encompassing nonHodgkin lymphoma (NHL) and Hodgkin lymphoma (HL). The majority of NHL cases originate from B cells. HL is characterized by the presence of rare Hodgkin and Reed-Sternberg cells. Within the context of the inflammatory response, two SH2 domain-containing protein tyrosine phosphatases (SHPs), namely S...... hiện toàn bộ

A study of seasonal rainfall in Vietnam at the end of 21st century according to the Non-Hydrostatic Regional Climate Model
Vietnam Journal of Science, Technology and Engineering - - 2018
Mau Nguyen-Dang, Truong Nguyen-Minh, Hidetaka SASAKI, Izuru TAKAYABU
This article presents analyses of changes in the seasonal characteristics of the far future climate (2080-2099) across Vietnam as projected by the Non-Hydrostatic Regional Climate Model (NHRCM) in terms of the RCP 8.5 (Representative Concentration Pathways 8.5) scenario. The results show significant changes in seasonal rainfall in Vietnam compared with the 1982- 2003 baseline period. Specifically,...... hiện toàn bộ

Evaluating the membrane fouling control ability of a reciprocation membrane bioreactor (rMBR) system
Vietnam Journal of Science, Technology and Engineering - Tập 62 Số 1 - Trang 50-54 - 2020
P.T. Nguyen, B.T. Dang, Q.T. Huynh, X.D. Nguyen, H.H. Nguyen, K.J. Lee, X.T. Bui
Membrane bioreactors (MBRs) are being increasingly applied to many full-scale plants around the world to treat both municipal and industrial wastewater. However, membrane fouling and energy consumption are significant challenges to broader applications of MBRs. By using a new MBR configuration, this research aims to compare the performance between a conventional MBR and a reciprocation MBR (rMBR) ...... hiện toàn bộ

DNA barcoding, an approach for molecular identification of Huyen-sam (Scrophularia L.) samples collected in Northern Vietnam
Vietnam Journal of Science, Technology and Engineering - Tập 60 Số 2 - Trang 56-64 - 2018
Manh Minh Bui, Anh Tuan Vu, Phuong Nhung Vu, Quang Cu Pham, Dang Ton Nguyen, Thi Thu Hue Huynh
Huyen-sam (Vietnamese name) which belongs to Scrophularia L. genus is a valuable herb. This medicinal plant is classified as Scrophularia ningpoensis Hemsl. Huyen-sam roots, which contain a large amount of bioactive compounds, have a similar morphology to its relatives. DNA barcodes promise to be a precise and reliable tool for distinguishing the processed Huyen-sam materials from their counterfei...... hiện toàn bộ

Thuy Lan Chi Nguyen, Thi Thu Huong Dinh, Thi Cam Tu Dang, Anh Duc Pham, Thanh Tam Nguyen, Thi Tu Quyen Huynh, Nhat Phuong Tran
The Tien Giang province is located in the tropical climate zone of the Mekong delta. In this study, the diversity of zooplankton and benthic macroinvertebrates were investigated in the estuarine coastal waters of the Tien Giang province of southern Vietnam. 10 sites were observed over six time periods from 2019 (March, May, September, and November) and 2020 (March and May). The taxonomic richness,...... hiện toàn bộ

Studying the characteristics of heavy rainfall in the central coastal provinces of Vietnam (Quang Binh case study)
Vietnam Journal of Science, Technology and Engineering - Tập 61 Số 2 - Trang 71-78 - 2019
Nguyen Van Thang, Vu Van Thang, Tran Dinh Trong, Jerome Faucet
This paper explores the maximum amount of rainfall in the Central coastal provinces of Vietnam (Quang Binh case study) for return periods of 5 years, 10 years, 20 years, 50 years, and 100 years, which correspond to frequencies of 20%, 10%, 5%, 2%, and 1%, respectively. The results show that at a frequency of 20%, the maximum intensity of rain during a heavy rain spell can range from 636.6 to 696.0...... hiện toàn bộ

Coronavirus disease 2019 (COVID-19), caused by the highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has resulted in widespread global morbidity and mortality, primarily affecting adults. However, the prevalence of severe illness in children is significantly lower, with most paediatric cases presenting mild symptoms or remaining asymptomatic. A minority of cases can p...... hiện toàn bộ
