AbstractKaempferia champasakensis Picheans. & Koonterm (Zingiberaceae) is locally known as "Dia Lien hoa trang" in Vietnam. Despite a previous study on the essential oils (EO) of K. leaves, no other studies have reported chemical components and biological activities champasakensis. Therefore, this aims to identify constituents EO from rhizomes evaluate their antimicrobial activity, which has been re-confirmed through molecular docking studies. The gas chromatography-mass spectrometry (GC/MS)...
This research explored the motivations, behaviors, and consequences of tax non-compliance aimed to provide empirical evidence evaluate impact knowledge, perceived non-tax opportunity felt loss on compliance in small medium enterprises (SMEs). A quantitative approach a panel 326 SMEs through SEM linear structural model analysis using SmartPLS software. The hypotheses were tested parallel mediation model. loss, contrast negatively affect taxpayers’ behavior tax-compliance level. two mediators,...
The study focuses on developing an effective adsorbent for the removal of Hexavalent chromium from aqueous solutions. It utilizes chemically modified sugarcane bagasse cellulose, enhanced with ascorbic acid, as material. A comprehensive model was established to examine both individual and combined effects different variables adsorption process, employing a central composite rotatable experimental design rooted in response surface methodology (RSM). underwent verification statistical...
Ung thư cổ tử cung là nguyên nhân gây vong hàng đầu cho phụ nữ, chiếm 12% trong các loại ung ở nữ giới. Có nhiều cách chẩn đoán nhưng phương pháp sàng lọc, bằng nhuộm Papanicolaou phổ biến nhất. Chăm sóc sức khỏe sinh sản chương trình mục tiêu y tế giai đoạn 2015-2020 tại Quảng Ninh, vì vậy chúng tôi triển khai nghiên cứu đánh giá tỷ lệ nhiễm, mắc từ 18 đến 69 tuổi trên địa bàn tỉnh Ninh 2018 -2020. Kết quả tổng số 680 đối tượng với kết ca và bị ASCUS, LSIL, HSIL 9/ 1,33% độ 48 55 tuổi....
This study focuses on the role of ChatGPT in supporting university teaching, particularly context digital transformation. It identifies opportunities and challenges while providing recommendations for more effective application technology education. Data was collected through a questionnaire distributed to 42 lecturers at Thai Nguyen University Education 13 semi-structured interviews. method helps clarify practical experiences supplement survey data.

This research collected starch films with varying Microcrystalline Cellulose (MCC) contents, ranging from 0% to 20% by weight.Subsequently, and these starch-MCC composite were assessed for their film-forming ability, solution properties, water absorption capacity, solubility, biodegradability, surface morphology.The film the best characteristics was selected further testing in preserving ripe tomatoes.The results showed that adding 4% MCC reduced enhanced biodegradability solubility an...
Nowadays, the developed countries have widely utilized image processing in Intelligent Transportation System (ITS), medical, biology and other fields. The quality enhancement is an important task, especially enhancing resolution of from new interpolated pixels. conventional Bicubic interpolation (BI) algorithm used a square matrix obtained by original neighbor pixels, which surrounds however lost depths boundary pixel value are blurred block artifact. This proposed aims to reduce effect...
In this work, the zinc/cobalt‐based zeolite imidazolate frameworks ((Co/Zn)ZIFs) were synthesized with solvothermal method. The obtained material was characterized by utilizing scanning electron microscopy (SEM), X‐ray diffraction (XRD), UV‐Vis diffusive reflectance spectroscopy, and nitrogen adsorption‐desorption isotherms. XRD SEM analyses show that (Co/Zn)ZIFs are composed of nanocrystals polyhedral shapes around 50–100 nm belong to I‐43m space group as those ZIF‐8 ZIF‐67. Optical studies...
AbstractMeistera, belongs to the Zingiberaceae family, is a genus of medicinal plants that contain rich resource essential oils (EOs) as well have many valuable bioactivities. The aim present study was investigate EOs Meistera vespertilio, which has not been reported before. were distilled by hydrodistillation method from M. vespertilio rhizomes collected in two different regions (Phu Tho and Nghe An Provinces) Vietnam. compositional analysis EO samples carried out using Gas...

The model treating negative ions initially...
Mangrove forests have been globally recognized as they play a vital role in preventing coastal erosion, mitigating the effects of wave actions, and protecting habitats adjacent shoreline land-uses from extreme events. Sentinel-1 (SAR) offers new opportunity for mangrove cover mapping biomass estimation, especially tropics where deforestation degradation are highest cloud is persistent. This study used Sentinel-1A-derived VV/VH polarizations with thresholds -23.5<VH<-9.05...
