Limited data are available on HIV viral suppression rates among men and women antiretroviral therapy (ART) factors associated with RNA load (VL) in Vietnam.We conducted a cross-sectional survey of 1255 adult patients ART for at least 1 year across four provinces Vietnam. Data collection included standardised questionnaire, routine laboratory testing, an VL assay. Bivariate logistic multivariate analyses were to assess unsuppressed VL.The median age was 34.5 years the time 46 months. Gender...
The evolution of polystyrene–polyisoprene block copolymer self-assembly is studied in coaxially electrospun nanofibers via annealing. leftmost image shows the cross-sectional and longitudinal sections as-spun fibers. Moving to right, a transition morphology can be seen from stacked disk structures for lower annealing temperatures alternating concentric cylinders polyisoprene polystyrene higher times.
The role of regulatory T cells (Tregs) in bacterial sepsis remains controversial because antibody-mediated depletion experiments gave conflicting results. We employed DEREG mice (DEpletion REGulatory cells) and a caecal ligation puncture model to elucidate the CD4+Foxp3+ Tregs sepsis. In natural can be visualized easily selectively depleted by diphtheria toxin animals express receptor enhanced green fluorescent protein as fusion under control foxp3 locus. confirmed rapid Treg-activation an...
Abstract This study applied an in situ electric contact resistance technique to monitor delamination induced by indentation loads. A suddenly increasing depth, together with a simultaneous drop monitoring current, suggests that occurred. During unloading processes, the rapid decrease both depth and current imply delaminated film was suspended as long load became sufficiently small. When occurred during oscillating found from initial value steady value, which is related loss of interfacial contact.
The performance of visual odometry is dependent upon the quality features selected for computing frame-to-frame transformation. In order to ensure features, conventional approaches consider spatial distribution in addition their counts and matching scores, which a small number are randomly from each uniformly distributed buckets. this paper, we show that can be optimally, rather than randomly, using well-defined mathematical formalism. proposed method optimal feature selection minimizes...
Planar surface patches, extracted for instance from a captured 3D point cloud, play an important role as feature in modeling and/or recognizing objects and environments. In terms of extracting such planar the main technical issue involved may be overcoming trade-off between accuracy computational efficiency, especially, when cloud is noisy. Conventionally, they have taken approaches that seek either high efficiency at expense or vice versa. This paper contributes advancement methodology...
This paper deals with dynamic analysis of a multi-span continuous beam an arbitrary number cracks. problem is solved by hybrid analytical/ numerical method that the basis for applying to damage detection in later. In this paper, we calculate detail about vibration frequencies, mode shape structure The proposed improved transfer matrix combined mode-superposition method. Only need use two unknowns, can solve Calculation cases cracks and without are compared previous studies.
Controlled modulus columns (CMC) for ground improvement are installed using a hollow stem displacement auger to induce lateral soil effect, followed by grout injection. While the method reduces spoils, excessive may damage adjacent structures. Although there has been growing interest in quantifying such effects, only handful of studies have attempted. This paper presents results numerical investigation on CMC installation effect an existing bridge pile three-dimensional finite difference...
Evolutionary algorithms (EAs) have been widely applied to solve many numerical and combinatorial optimization problems. A special paradigm of EAs has promoted allowing several populations co-evolve together. During evolution process these can be either cooperative or competitive. The co-evolution evolutionary algorithm (CCEA) shown a great deal in solving large complex However, there are limited studies on parallelizing algorithms. In this paper, we propose an approach combining CCEA with...
3D vision-based recognition as well grasping of complex objects is required not only for detection and categorization but also pose estimation robotic pick-and-place operations. In this paper, we propose a structured light camera based visual perception tracking system application with robot arm manufacturing. the first step, use geometric surface primitive patch segmentation approach on Hough transforms to obtain accurate normal estimations from point clouds identification primitives. The...
Nematode communities in black pepper (Piper nigrum L.) agricultural soil Thanh An, Binh Phuoc province, were investigated. Soil samples collected February 2012 at 9 selected sites belonging to 3 groves. The structure of nematode and critical ecological indices determined estimate environmental status. 26 genera found. Of those, plant parasitic nematodes such as Meloidogyne, Helicotylenchus, Hoplolaimus, Psilenchus, Tylenchidae always appear with high frequency density, whereas the...
Abstract This work examined the synthesis, antibacterial activity, and decolourisation of WO 3 @Graphene nanorods (WO @Gr NR). NR nanocomposite was in situ produced via a facile one-step hydrothermal process employing sodium tungstate dihydrate exfoliated graphene as precursors. The resulted exhibited an average diameter 13 nm, large specific surface area 53.3 m 2 g −1 , bimodal pore size distribution with 5.5 nm. optical bandgap is extrapolated to be 2.75 eV. Graphene shown responsible for...
Pepper (Piper nigrum L.) is a high economic value plant species that brings the main income to people at Loc Hung commune. So pepper’s yield plays significant role in people’s life this region. To assess influence of environmental factors on growth and development pepper, we need analyse structural characteristics soil nematode communities order promptly detect levels parasitic nematodes infection as well assessment environment status based communities. Study results five sampling stations...
Hilbert-Huang transform (HHT) is a signal processing technique relatively strong and effective today, to overcome the limitations of used techniques have been widely as traditional Fourier or Wavelet transform. can handle effectively nonstationary nonlinear signal. In this paper present how use HHT method detect damage beams under effect moving load. Location determined by observing changes in first instantaneous frequency curve (IF1), location highest peak IF curve. This briefly described...
Controlled modulus columns (CMC) ground improvement technique is a novel approach to reduce settlement. To install CMC, rotary displacement auger used form vertical cylindrical cavity, by displacing the surrounding soils laterally, followed grout injection. While method reduces spoil generation, excessive lateral soil may damage adjacent structures and freshly-grouted CMCs. Although there has been growing interest in quantifying such effects, only handful of studies have attempted. This...
A method used to determine the residual stress in a hard film deposited on soft substrate via unloading load-depth curves was proposed. The with transitional behaviors were deflection stiffness, and then stresses obtained. Significant extra induced by cube corner indenter at large depth. In contrast, indentation-induced could be neglected cases of Berkovich indentation relatively small depths.
This study was conducted at the Maize Research Instituteof Vietnam using 24 maize hybrids, identified as STM1 to STM24, five different salt concentrations, which were 0, 50, 100, 150, and 200 mM NaCl. After seven days of germination room temperature, seedlings transplanted nutrient-rich solutions salinized with salt. 17 day-old then harvested calculate their growth parameters day fully wilt degradation, root shoot length, seedling dry matter production, content.
