Stability Analysis of Multiple LEDs Dimming Circuits: An Interaction between an LC Input Filter and Two Buck Converters
No full textAbstractThis paper proposes an average modeling of LED dimming circuits controlled by an indirect sliding mode technique. The circuit and control parameters that affect a multiple LED dimming system's stability are studied. The dimming system comprises two output-capacitorless buck converters and each converter connected to two strings of LEDs as a load. These dimming buck converters are connected to a 48V power source via an LC filter to reduce the input ripple current. It is known that fast response dc-dc converter might lead to unstable operation of the system due to its negative input resistance characteristic. This paper investigates the control parameters of the sliding control that affect dynamics of a DC bus due to the change of the operating point of LED. The theoretical model is validated through experimental results obtained from the test bench
Development and assessment of a Real-Time PCR assay for the rapid and sensitive detection of a novel thermotolerant bacterium, Lactobacillus thermotolerans, in chicken feces
Full text linkA new real-time PCR assay was successfully developed using a TaqMan fluorescence probe for specific detection and enumeration of a novel bacterium, Lactobacillus thermotolerans, in chicken feces. The specific primers and probe were designed based on the L. thermotolerans 16S rRNA gene sequences, and these sequences were compared to those of all available 16S rRNA genes in the GenBank database. The assay, targeting 16S rRNA gene, was evaluated using DNA from a pure culture of L. thermotolerans, DNA from the closely related bacteria Lactobacillus mucosae DSM 13345T and Lactobacillus fermentum JCM 1173T, and DNA from other lactic acid bacteria in quantitative experiments. Serial dilutions of L. thermotolerans DNA were used as external standards for calibration. The minimum detection limit of this technique was 1.84 x 103 cells/ml of an L. thermotolerans pure culture. The assay was then applied to chicken feces in two different trials. In the first trial, the cell population was 104 cells/g feces on day 4 and 105 cells/g feces on days 11 to 18. However, cell populations of 106 to 107 cells/g feces were detected in the second trial. The total bacterial count, measured by 4',6-diamidino-2-phenylindole (DAPI) staining, was approximately 1011 cells/g feces. These results suggest that in general, L. thermotolerans is a normal member of the chicken gut microbiota, although it is present at relatively low levels in the feces

Myzorhynchus series of Anopheles mosquitoes as potential vectors of Plasmodium bubalis in Thailand
No full textUngulate malaria parasites and their vectors are among the least studied when compared to other medically important species. As a result, a thorough understanding of ungulate malaria parasites, hosts, and mosquito vectors has been lacking, necessitating additional research efforts. This study aimed to identify the vector(s) of Plasmodium bubalis. A total of 187 female mosquitoes (133 Anopheles spp., 24 Culex spp., 24 Aedes spp., and 6 Mansonia spp. collected from a buffalo farm in Thailand where concurrently collected water buffalo samples were examined and we found only Anopheles spp. samples were P. bubalis positive. Molecular identification of anopheline mosquito species was conducted by sequencing of the PCR products targeting cytochrome c oxidase subunit 1 (cox1), cytochrome c oxidase subunit 2 (cox2), and internal transcribed spacer 2 (ITS2) markers. We observed 5 distinct groups of anopheline mosquitoes: Barbirostris, Hyrcanus, Ludlowae, Funestus, and Jamesii groups. The Barbirostris group (Anopheles wejchoochotei or Anopheles campestris) and the Hyrcanus group (Anopheles peditaeniatus) were positive for P. bubalis. Thus, for the first time, our study implicated these anopheline mosquito species as probable vectors of P. bubalis in Thailand. © 2022, The Author(s)
Tissue Microbiome Profiling Identifies an Enrichment of Specific Enteric Bacteria in Opisthorchis viverrini Associated Cholangiocarcinoma
No full textAbstractCholangiocarcinoma (CCA) is the primary cancer of the bile duct system. The role of bile duct tissue microbiomes in CCA tumorigenesis is unestablished. To address this, sixty primary CCA tumors and matched normals, from both liver fluke (Opisthorchis viverrini) associated (OVa, n=28) and non-O. viverrini associated (non-OVa, n=32) cancers, were profiled using high-throughput 16S rRNA sequencing. A distinct, tissue-specific microbiome dominated by the bacterial families Dietziaceae, Pseudomonadaceae and Oxalobacteraceae was observed in bile duct tissues. Systemic perturbation of the microbiome was noted in tumor and paired normal samples (vs non-cancer normals) for several bacterial families with a significant increase in Stenotrophomonas species distinguishing tumors vs paired normals. Comparison of parasite associated (OVa) vs non-associated (non-OVa) groups identified enrichment for specific enteric bacteria (Bifidobacteriaceae, Enterobacteriaceae and Enterococcaceae). One of the enriched families, Bifidobacteriaceae, was found to be dominant in the O. viverrini microbiome, providing a mechanistic link to the parasite. Functional analysis and comparison of CCA microbiomes revealed higher potential for producing bile acids and ammonia in OVa tissues, linking the altered microbiota to carcinogenesis. These results define how the unique microbial communities resident in the bile duct, parasitic infections and the tissue microenvironment can influence each other, and contribute to cancer
Characteristics of Biochar Production Derived from Bamboo in a Drum Pyrolyzer
Full text linkThis study utilizes a drum pyrolyzer to investigate the production of biochar and wood vinegar from bamboo. Bamboo from Prachinburi province in Thailand was used in the experiment. Bamboo was heated to a temperature between 450 °C and 595 °C in a drum pyrolyzer (cylindrical shape). The yields of biochar, wood vinegar, and gaseous products following the pyrolysis process were at 34.6%, 16.6%, and 48.8%, respectively. Based on calculations using the yield of biochar and the heating values of both biochar and raw fuel, the pyrolyzer's energy conversion efficiency was at 44.6%. With moisture content dropping from 11.1% to 4.94%, volatile matter dropping from 78.0% to 39.2%, and fixed carbon rising from 19.8% to 52.4%, the resultant bamboo biochar displayed better properties than the raw material. Compared to the raw bamboo's 19.1 MJ/kg, the biochar's higher heating value (HHV) increased to 24.6 MJ/kg. During the pyrolysis process, the pH of the wood vinegar generated ranged from 2.85 to 3.18. Based on a one-year project timeline, the process showed economic potential with a monthly internal rate of return of 46.75% and a payback period of about two months
