Molecular Analysis of Bacterial Meningitis in Suspected Cases

One hundred and seventy-six cases of suspected meningitis (SMN) were included in a cross-sectional study. Their ages ranged from less than 1 year to 80 years, of whom 44.3% were male. The aim was to assess bacterial meningitis (BMN) in terms of incidence and types of causative bacteria. Cerebrospinal fluid (CSF) specimens were collected and polymerase chain reaction (PCR) analysis was conducted with universal primers designed to amplify a DNA fragment (996 bp) of the 16S rRNA gene of eubacteria. Resolving PCR products in agarose-gel electrophoresis revealed that 37.5% of CSF specimens were PCR positive, while 62.5% of CSF specimens showed no band and were considered PCR-negative. Eighty percent of the latter specimens were noted to have pleocytosis, in addition to having protein and/or glucose concentrations lower or higher than those in the normal range (abnormal CSF). The remaining 20.0% of CSF specimens were considered normal regarding pleocytosis, protein, and glucose (normal CSF). When the amplified DNA of PCR-positive specimens was subjected to sequencing and alignment with reference sequences, both Gram-negative (GN) and Gram-positive (GP) bacteria were identified (23 and 9 types, respectively). Acinetobacter spp. and Pseudomonas spp. were the most common GN bacteria (each with 17.8%), while Staphylococcus spp. was the most common GP bacteria (43.75%). The study concluded that BMN presents an important public health challenge, and PCR analysis of the CSF was an effective method for diagnosing pathogenic bacteria in SMN. In addition, leukocytes, glucose, and protein are valuable CSF parameters that may aid in the diagnosis of BMN.
Implementation of Interactive Learning Model Based on Learning by Asking with the Assistance of Virtual Mentors to Improve Learning Outcomes Students

This research aims to apply an interactive learning model based on asking questions with the use of a virtual mentor. The method used in this research is quasi-experimental. The research results showed that the validation scores for interactive learning media by material experts and media experts were respectively 72 and 58 in the very appropriate category. The results of learning media readability test were 82.18 in the very good category. The pretest result of students in control class was 48.6 while the posttest was 73.68. Experimental class, pretest score was 49.87 and posttest score was 80.76. The N-gain values ​​for the control and experimental classes are 0.48 and 0.61 respectively. Based on the research results, it is known that student learning outcomes increased in both the control and experimental classes, but the increase in the experimental class was higher than in the control class. This is because the experimental class uses an interactive learning model based on learning to ask questions assisted by a virtual mentor. The conclusion of this research is that the implementation of an interactive learning model based on learning by asking with the help of a virtual mentor is effective in improving student learning outcomes.
Spatial and Temporal Dynamics of Phytoplankton Communities in a Freshwater Tidal Estuary (Schelde, Belgium)

Abstract During the course of 1996, the brackish to freshwater tidal reaches of the Schelde Estuary were sampled monthly along a longitudinal transect to study the origin and composition of phytoplankton communities in the freshwater tidal estuary. Variation in the phytoplankton community as a whole and its relation with the abiotic environment was analysed using multivariate analysis with variation partitioning. Of the variation in the species data 23·4% was spatially structured and a large part (13·8%) was explained by salinity or factors co-varying with salinity, with a marked species succession observed along the salinity gradient. Spatial variation not related to salinity (9·6%) was mainly situated within the freshwater tidal reaches, where in the uppermost stations phytoplankton was imported from the riverine tributaries while in the more downstream situated stations it was produced in situ . Riverine phytoplankton declined after import into the estuary where it was replaced by autochthonous, estuarine populations which were adapted to the low light climate and/or resistant to rotifer grazing. Of the species variation 27·8% was temporally structured. While riverine blooms appeared to be initiated by an increase in irradiance a decrease in river discharge in spring, estuarine phytoplankton only developed in summer, when temperature increased. Some potentials and limitations of the use of multivariate analyses with variation partitioning in pelagic estuarine environments are discussed in view of our results.
Concave microlens arrays with tunable curvature for enhanced photodegradation of organic pollutants in water: A non‐contact approach

Solar‐driven photodegradation for water treatment faces challenges such as low energy conversion rates, high maintenance costs, and over‐sensitivity to the environment. In this study, we develop reusable concave microlens arrays (MLAs) for more efficient solar photodegradation by optimizing light distribution. Concave MLAs with the base radius of μm are fabricated by imprinting convex MLAs to polydimethylsiloxane elastomers. Concave MLAs possess a non‐contact reactor configuration, preventing MLAs from detaching or being contaminated. By precisely controlling the solvent exchange, concave MLAs are fabricated with well‐defined curvature and adjustable volume on femtoliter scale. The focusing effects of MLAs are examined, and good agreement is presented between experiments and simulations. The photodegradation efficiency of organic pollutants in water is significantly enhanced by 5.1‐fold, attributed to higher intensity at focal points of concave MLAs. Furthermore, enhanced photodegradation by concave MLAs is demonstrated under low light irradiation, applicable to real river water and highly turbid water.image
A Low-Cost Hydrographic Kayak Surveying System

Abstract A low-cost hydrographic kayak surveying system was developed and is described here. The kayak survey system is an extremely flexible surveying system; it can be easily deployed in the nearshore, small lakes, and in other small bodies of water where engine-equipped vessels are prohibited. The cost and complexity of the system are minimized by using a low-cost L1 handheld global positioning system (GPS) system, a smart 200 kHz echosounder that outputs a serial depth string, and a simple off-the-shelf serial data acquisition system. The vertical and horizontal errors of the handheld GPS system are evaluated with an inexpensive external L1 patch antenna and a more expensive, nonpatch L1 antenna, resulting in vertical root-mean-square errors of 11 and 2.5 cm, respectively. In addition, bathymetric measurements at Bethany Beach, Delaware, were obtained using the kayak surveying system and compared to a wading and boat survey yielding a root-mean-square error of 17 cm. The kayak surveying system provides an easily constructed, environmentally friendly, low-cost surveying alternative to conventional and personal water craft surveying systems.
Coherence and Gap Between Service Quality Attributes and Customer Satisfaction

Service conformance to customer expectations is measured in terms of service quality. In order to enhance their services, spot issues as they arise, and more accurately gauge customer satisfaction, service business owners frequently evaluate the quality of the services they offer to their clients. The link between sustainable product qualities and consumer decision-making has been the subject of significant research advancements in recent decades. Nonetheless, despite the substantial quantity of research, conclusions are still dispersed and occasionally even inconsistent. Because customers' assessments of service quality vary widely, the goal of this study is to demonstrate analytically and empirically how the SERVQUAL dimensions are coherent across service industries and even within the same service industry. Because the five SERVQUAL dimensions do not correspond to a customer's psychometric aspects of service quality, this conclusion suggests that there is a gap and lack of coherence between SERVQUAL's five dimensions and customer satisfaction.
Community Empowerment through Organic Waste Processing

Bukittinggi is the largest wholesale trade center on the island of Sumatra. In the economic sector, Bukittinggi is the city with the second-largest GRDP in West Sumatra. The most visited tourist spot is Jam Gadang. Throughout 2020, the volume of waste in Bukittinggi City transported to the landfill in Payakumbuh was 40,424 tons, or 110.25 tons/day. This number increased compared to the volume in 2019 of 32,236 tons or 107.4 tons/day. Based on these problems, community solutions are needed. The solution offered is separating and processing organic waste into eco enzymes as a solution to reduce the accumulation of organic waste. Eco enzyme is a liquid extract produced from fermenting leftover vegetables and fruit with brown sugar as a substrate. The activity plan is carried out with the main aim of overcoming problems that occur in partner communities as previously described. This Community Partnership Program uses counseling and training methods for making Eco Enzyme from organic waste so that community groups in Pulai Anak Air Bukittinggi Village can manage organic waste into fertilizer, cleaners, etc. The activity stages begin with the preparation stage, the implementation stage, and end with the monitoring and evaluation stage. The output targets to be achieved include articles, activity videos, liquid fertilizer, cleaners, etc. which can be used by the community, especially the PKK and Pokdarwis groups in Pulai Anak Air Bukittinggi Village.
Nitrogen and water management strategies to reduce nitrate leaching under irrigated maize

Cropping systems that fail to integrate nitrogen (N) water management are frequently associated with elevated concentrations of nitrate-N in soil and groundwater. Examples of poorly integrated management practices are abundant, especially where irrigation is used to minimize the effects of drought and N fertilizer is inexpensive. Two maize fields under improved water and N management practices at the Nebraska Management Systems Evaluation Area (MSEA) project were compared with an adjacent field under conventional furrow irrigation that followed management guidelines mandated by the local Natural Resources District. Surge-flow furrow irrigation with laser grading and a runoff-water recovery system reduced water application by 45-69% compared to conventional furrow irrigation over the three years of this study. Center-pivot sprinkler irrigation reduced water application by 60-72% compared to conventional furrow irrigation. Uniformity of water application was improved with the surge-flow and sprinkler irrigation systems, which made it reasonable to consider adding fertilizer N in the water (fertigation) to meet crop needs. The spoon-feeding strategy, based on chlorophyll meter readings to schedule fertigation, saved 168 kg ha-1 N the first year and 105 kg ha ] N the second year without reducing yields. Near total reliance of fertigation to meet crop N needs resulted in a 15% yield reduction the second year because spatial variability in soil N status made it difficult to collect representative chlorophyll meter data. Plot studies showed chlorophyll meter readings and yields were consistently higher for maize following soybean than where maize was grown in monoculture.
Lawsonia inermis (Lythraceae): From the Wild to the Garden

This study is a successful effort undertaken to introduce Lawsonia inermis a native plant, to the landscape industry. It can be propagated by seeds. However, seeds are not available throughout the year. Therefore, the present study was conducted with the objective of identifying a suitable propagule and a media to propagate L. inermis. Flowering phenology, including animal visitors were observed to elucidate the landscape potential of the plant. In the propagation experiment three maturity stages of stem cuttings viz. softwood, semi hardwood and hardwood were planted in two different media (sand, sand + coir dust 1:1). The layout of the experiment was Randomized completely block design. Twelve weeks after planting, rooting percentage, root dry weight and root number were recorded. Mass flowering was recorded twice a year in L. inermis where 75% of the canopy was covered with flowers. Flowers are attractive, scented and bloomed in the morning and last for two days. It attracts butterflies, bees and birds. Tree architecture is attractive and the plant can fit into a small space. It is also capable of tolerating adverse environmental conditions. A significant difference was observed in root dry weight and number of roots produced in different treatment combinations and softwood cuttings recorded the highest rooting percentage (71 %) in sand medium. Therefore, L. inermis can be promoted in urban landscaping and as a solution to the scarcity of planting material, softwood cutting grown in sand media can be recommended as the potential propagule and the media to introduce Lawsonia inermis to the landscape industry in Sri Lanka.

Agronomic performance of green corn at different sowing times and nitrogen doses

The present study aimed to identify the best sowing time and the best nitrogen dose in topdressing of the corn crop for "green ear" consumption. The experiment was conducted between October 2018 and June 2019 in a commercial crop, in Ipameri, Goiás, Brazil. The soil in the experimental area is classified as dystrophic Red-Yellow Latosol with clayey texture. The experimental design used was the randomized blocks, in a 5 x 5 factorial scheme, with five sowing times [1st (10/19/2018); 2nd (11/29/2018); 3rd (01/08/2019); 4th (02/18/2019) and 5th (03/28/2019)], implemented with 40 days intervals, after the first sowing, and five nitrogen doses (0, 50, 100, 150, and 200 kg ha-1), with four replicates. The following factors were evaluated for each sowing time: relative chlorophyll index, leaf dry mass, leaf nitrogen content, plant height, first ear insertion height, ears diameter and length, the total yield of ears with husks, the yield of commercial ears without husks and grain yield. The data were submitted to the analysis of variance (F-test). The sowing times and nitrogen doses in topdressing influenced the leaf nitrogen content, relative chlorophyll index, leaf dry mass, yield, and most of its components. Thus, it can be indicated that the best time for sowing corn for fresh consumption is in October (1st sowing time), and the estimated nitrogen dose in topdressing to obtain the maximum yield is 160 kg ha-1 of nitrogen.
Diagnostic Accuracy of [68Ga]Ga Labeled Fibroblast-Activation Protein Inhibitors in Detecting Head and Neck Cancer Lesions Using Positron Emission Tomography: A Systematic Review and a Meta-Analysis

Several studies have examined the use of positron emission tomography (PET) using [68Ga]Ga-radiolabeled fibroblast-activation protein inhibitors (FAPi) across multiple subtypes of head and neck cancer (HNC). The purpose of the present study was to evaluate the diagnostic accuracy of a newly developed molecular imaging approach in the context of HNC through a comprehensive review and meta-analysis. A thorough literature review was conducted to identify scholarly articles about the diagnostic effectiveness of FAP-targeted PET imaging. The present study incorporates original publications assessing the efficacy of this innovative molecular imaging test in both newly diagnosed and previously treated HNC patients. This systematic review examined eleven investigations, of which nine were deemed suitable for inclusion in the subsequent meta-analysis. The quantitative synthesis yielded a pooled detection rate of 99% for primary HNC lesions. Additionally, on a per patient-based analysis, the pooled sensitivity and specificity for regional lymph node metastases were found to be 90% and 84%, respectively. The analysis revealed a statistical heterogeneity among the studies for the detection rate of primary HNC lesions. The quantitative findings presented in this study indicate a favorable diagnostic performance of FAP-targeted PET imaging in detecting primary HNC tumors. In contrast, discordant results concerning the diagnostic accuracy of lymph node metastases were found. However, further multicentric trials are required to validate the efficacy of FAP-targeted PET in this specific group of patients.
A genetic analysis of Baishan molybdenum deposit in East Tianshan area, Xinjiang

The Baishan molybdenum deposit is located in the eastern Jueluotag tectonic belt of the East Tianshan Mountains. The wall rocks are biotite-felsic hornstone with well-developed mineralized quartz veins, belonging to Lower Carboniferous Gandun Formation (C1g). The H, O compositions of the hydrothermal fluids in the quartz veins are as follows: δ18OSMOW values are 9.1‰～10.0‰ with an average of 9.425‰, δ18OH2O balanced with quartz are 3.357‰ ～4.257‰ with an average of 3.682‰, and δDSMOW are -105‰～ -69%, with an average of -89.25‰. Characteristics of H, O isotopes indicate that the ore-forming hydrothermal fluid was dominated by magmatic water with the participation of some evolutionary meteoric water that had experienced the water-rock interaction. The magmatic water supplied the main metallogenic materials, and the evolutionary meteoric water served as an important factor for the precipitation of the metallogenic materials. The Re-Os isochronal age of molybdenites is (227.7±4.3) Ma(MSWD=0.32), suggesting that the mineralization of the ore deposit took place in Middle Triassic. These geological and geochemical characteristics imply that the Baishan Mo deposit is a porphyry deposit, and its metallogenic materials mainly came from deep granitic rock. This paper deals with metallogenic background, and the authors hold that the Baishan molybdenum deposit was formed in a compression environment after the post-collisional stage, and its mineralization was controlled by the distant effect of the Paleo-Tethys Ocean in Triassic. This paper has supplied a solid foundation for further researches on mineralization of granitoids which intruded into the same tectonic background in Jueluotag block as well as in East Tianshan area.
Landscape structural features control fire size in a Mediterranean forested area of central Spain.

Landscape structure may affect fire propagation and fire size. Propagation may be favoured in landscapes that are homogeneous and hindered at places of greater heterogeneity, and where discontinuities occur. We tested whether there is continuity in landscape structure across the edges of 110 fires in the Sierra de Gredos (central Spain). We used Landsat Multispectral Scanner images to map and assess the land-cover composition and other features of fires. Landscape diversity along the pixel row of the fire edge and of the two adjacent ones (burned and unburned) was compared for all fires. Additionally, changes in landscape properties and fuel hazard perpendicular to the fire edge evaluated the degree of discontinuity from inside the burn towards the outside across the edge. Fire size was related to landscape properties and weather conditions using generalized linear regression models. Diversity increased from inside the burn towards the edge and outside the burn. Discontinuity in land-cover types and fuel hazard increased from the inside towards the outside. Modelling confirmed that fire size was in part related to landscape characteristics of the burned area and of the edges of the fire perimeter. We conclude that landscape structure was important in determining fire size in this area.
Factors that influence the dominance of an enterprise reference architecture

Reference architectures provide template solutions for particular domains and can therefore be considered as standards. This study investigates whether diversity in enterprise reference architectures is likely to continue or if one reference architecture will gain dominance in the market. More specifically, we examine factors that lead to market dominance. We use the literature on standards battles, the Technology Acceptance Model (TAM), and the Technology-Organization-Environment (TOE) framework to analyse factors for dominance. In this field, network effects apply and provide a force towards the dominance of a single architecture. However, factors contributing to multiple standards are more relevant, as well as those from TAM and TOE, since reference architectures differ slightly in their added value for various categories of stakeholders. Empirical data from 19 expert interviews provide further insights into the factors that influence the dominance of an enterprise reference architecture. Our results show that it is important that the content and value of reference architectures are straightforward and understandable, not only for architects but for all stakeholders. We extend current standards battles literature by applying it to a new area and combining it with TAM and TOE. We provide an innovative and extensive list of factors that influence the dominance of one standard and the continued coexistence of multiple standards and relate these to phases of technology development. This list can form a framework for future standards battle research. From the practical perspective, the annex may help parties involved in standard battles to position themselves in the technology development phase, better predict the outcome of the battle, and enhance the possibility to influence that outcome. More specifically, our paper will help adopters of enterprise reference architectures to make better-informed choices. Suppliers of reference architectures can use the findings to stimulate market adoption of their model.
High risk HPV-positive women cervicovaginal microbial profiles in a Greek cohort: a retrospective analysis of the GRECOSELF study

Increasing evidence supports a role for the vaginal microbiome (VM) in the severity of HPV infection and its potential link to cervical intraepithelial neoplasia. However, a lot remains unclear regarding the precise role of certain bacteria in the context of HPV positivity and persistence of infection. Here, using next generation sequencing (NGS), we comprehensively profiled the VM in a series of 877 women who tested positive for at least one high risk HPV (hrHPV) type with the COBAS® 4,800 assay, after self-collection of a cervico-vaginal sample. Starting from gDNA, we PCR amplified the V3–V4 region of the bacterial 16S rRNA gene and applied a paired-end NGS protocol (Illumina). We report significant differences in the abundance of certain bacteria compared among different HPV-types, more particularly concerning species assigned to Lacticaseibacillus, Megasphaera and Sneathia genera. Especially for Lacticaseibacillus, we observed significant depletion in the case of HPV16, HPV18 versus hrHPVother. Overall, our results suggest that the presence or absence of specific cervicovaginal microbial genera may be linked to the observed severity in hrHPV infection, particularly in the case of HPV16, 18 types.
