Ultra-Trace Determination of Sudan I, II, III, and IV in Wastewater by Solid-Phase Microextraction (SPME) and on-Line Solid-Phase Extraction (SPE) with High-Performance Liquid Chromatography (HPLC)

Field: Chemistry (Physical Sciences)

Two extraction/preconcentration methods are reported for the high-performance liquid chromatography (HPLC) determination of Sudan I, II, III, and IV in wastewater at trace (μg/L) and ultra-trace (ng/L) levels for the first time. The first approach, based on solid-phase microextraction (SPME), allows sub-μg/L determination of Sudan I and II, while Sudan III and IV are not detectable at these levels due to strong binding to dissolved organic matter. For Sudan I and II, the linearity was tested in the range from 0.5 to 50 μg/L and limits of detection (based on a signal-to-noise ratio of 3) and quantification (based on a signal-to-noise ratio of 10) of 0.2 and 0.5 μg/L, respectively, were estimated for both dyes. The on-line solid-phase extraction (SPE) using a C18 based enrichment precolumn was employed in the second approach. The only sample pretreatment employed was a required centrifugation step to remove suspended solids. In this case, the linearity was verified in the range from 50 to 500 ng/L for Sudan I, II, and III and from 100 to 500 ng/L for Sudan IV. The detection limits for a sample volume of 20 mL were on the order of 20 ng/L for Sudan I, 25 ng/L for Sudan II and III, and 30 ng/L for Sudan IV.
FDI, Exports, and GDP in East and Southeast Asia — Panel Data versus Time-Series Causality Analyses

Field: Economics, Econometrics and Finance (Social Sciences)

Foreign direct investment (FDI) discussed in Chapter 2 is only one of the growth factors in economic development. Other major factors are exports and gross domestic product (GDP). What are the causal relations among these three factors? Economists often take two of the three variables at once and find the effects of one variable on the other using time-series analysis, presumably because that simplifies the analysis. Thus, each country has different relations and no unified theory emerges. In this chapter, we consider all three factors simultaneously and compare the results from time-series analysis and panel data analysis. For the first time in the literature, we present the theoretical framework of the vector autoregression (VAR) form for the Granger causality tests. We then use time-series and panel data from 1986 to 2004 to examine the Granger causality relations between GDP, exports, and FDI among China, Korea, Taiwan, Hong Kong, Singapore, Malaysia, the Philippines, and Thailand and the eight rapidly developing East and Southeast Asian economies. After reviewing the current literature and testing the properties of individual time-series data, we estimate the VAR of the three variables to find various Granger causal relations for each of the eight economies. We find that each country has different causality relations and, therefore, the analysis does not yield general rules. We then construct the panel data of the three variables for the eight economies as a group, and we use the fixed effects and random effects methods to estimate the panel data VAR equations for Granger causality tests. The panel data causality results reveal that FDI has unidirectional effects on GDP directly and indirectly through exports, and there also exists bidirectional causality between exports and GDP for the group. Our results indicate that the panel data causality analysis has superior results over the time-series causality analysis. Economic and policy implications of our analyses are then explored in the conclusions.
Analysis of Postoperative Gait, Hip Strength, and Patient-Reported Outcomes After OTA/AO 61-B and 61-C Pelvic Ring Injuries

Field: Medicine (Health Sciences)

Objectives: To examine clinical gait parameters, hip muscle strength, pelvic functional outcomes, and psychological outcomes after surgical fixation of OTA/AO 61-B and 61-C pelvic ring injuries. Design: Retrospective review identified 10 OTA/AO 61-B patients and 9 OTA/AO 61-C patients for recruitment who were between 1 and 5 years after pelvic fixation. Gait and strength assessments, and patient-reported outcome scores were performed/collected and analyzed. Setting: Outpatient clinical motion performance laboratory. Patients/Participants: Patients with OTA/AO 61-B and OTA/AO 61-C fractures who were between 1 and 5 years after pelvic fixation. Main Outcome Measurements: Hip strength, kinetics, and spatial–temporal outcomes; Majeed Pelvic Outcome Score; Short Form 36; Hamilton Anxiety/Depression Rating Scales. Results: There were no differences in age, body mass index, or time since definitive fixation between OTA/AO 61-B and 61-C groups. The OTA/AO 61-C group had higher median injury severity scores, longer length of stay, and greater postoperative pelvic fracture displacement. There was no difference in bilateral hip strength, bilateral peak hip moments, peak hip power, and walking speed between groups. Patients with OTA/AO 61-C fractures had lower scores on Short Form 36 General Health and Majeed Work, with a trend toward a lower Total Majeed score. There were no differences in self-reported total anxiety and depression symptoms. Conclusions: This study did not identify any gait, strength, or psychological differences between OTA/AO 61-B and 61-C injuries at 1–5 years of follow-up. However, increased injury severity in OTA/AO 61-C patients may have residual consequences on perceived general health and ability to work. This pilot study establishes a template for future research into functional recovery of patients with severe pelvic ring trauma. Level of Evidence: Prognostic Level III.

Comparison of Laser Coordinate Measurements and Hierarchical Multiscale Finite Element Models for the Cup Drawing of Three Commercial Aluminum Alloys

Field: Engineering (Physical Sciences)

Abstract Cup drawing is a benchmark experiment frequently used to validate anisotropic constitutive models and multiscale crystal plasticity codes for yield locus prediction. Earing of the cup rim and thickness variation along the cup wall are sensitive to plastic anisotropy. This test was implemented on an industrial forming press and applied to 85 mm diameter disks of commercial AA1100, AA3103, and AA5005 alloy sheet. Cup geometry was determined using a laser probe coordinate measurement machine (CMM). Finite element models (FEM) were developed with ABAQUS Explicit software and a user-defined subroutine for the anisotropic yield locus based on the hierarchical multiscale model (HMS). As the coordinate cloud produced by the CMM is unrelated to the nodes of the deformed FEM-mesh, both were fitted to a polynomial-Fourier series expansion. After cleaning and correction of the CMM data, point-by-point comparison can be performed between model and experiment. For AA1100, the position of the ears was correctly identified but their magnitude was underestimated. Excellent coincidence was found for AA5005, with strong ears at 0 and 90°. The small ears at -30° and 30° and secondary ears at 90° were correctly predicted for AA3013.
Distinct Gut and Skin Microbiomes of a Carnivorous Caecilian Larva (Ichthyophis bannanicus) Show Ecological and Phylogenetic Divergence from Anuran Tadpoles

Field: Immunology and Microbiology (Life Sciences)

The amphibian microbiome plays a vital role in host health, yet the bacterial communities of caecilians (Order: Gymnophiona) remain largely uncharacterised. We investigated this by providing the first characterisation of the gut and skin microbiome of larval Ichthyophis bannanicus, a carnivorous caecilian, using 16S rRNA gene metabarcoding. Our analyses show distinct communities between the faecal samples and skin, with significant enrichment of Laribacter in faeces and Flavobacterium on skin. Despite significant variation in their community structures, the core genera Escherichia-Shigella were shared between both regions, suggesting similar microbial exchange in the aquatic environments. Skin bacterial diversity exhibited relatively higher richness, but lower evenness than that of faeces. Further, the skin bacterial community exhibited more complex interactions, suggesting stronger resilience to changes. The relationships and interactions of skin and faecal bacterial communities suggest their interactive effects on the host’s overall health. Compared with anuran tadpoles, the I. bannanicus larval microbiome showed taxonomic overlap, but possessed certain unique core bacteria. This work on an understudied amphibian lineage is foundational, highlighting how diet, phylogeny, and aquatic environment shape microbial communities and informing future research into amphibian health and disease.

Community paediatric respiratory infection surveillance study protocol: a feasibility, prospective inception cohort study

Field: Medicine (Health Sciences)

Introduction Paediatric respiratory tract infections (RTIs) are common reasons for primary care consultations and antibiotic prescribing. Locally relevant syndromic and microbiological surveillance information has the potential to improve the care of children with RTIs by normalising illness (parents) and reducing uncertainty (clinicians). Currently, most RTI studies are conducted at the point of healthcare service consultation, leaving the community burden, microbiology, symptom duration and proportion consulting largely unknown. This study seeks to establish the feasibility of (mainly online) participant recruitment and retention, and the acceptability/comparability of parent versus nurse-collected microbiological sampling, to inform the design of a future surveillance intervention study. Evidence regarding consultation rates and symptom duration is also sought. Methods and analysis A community-based, feasibility prospective inception cohort study, recruiting children aged ≥3 months and <16 years and their parents via general practitioner surgery invitation letter, aiming to collect data on 300 incident RTIs by July 2016. Following informed consent, parents provide baseline (demographic) data online, and respond to weekly emails to confirm the absence/presence of new RTI symptoms. Once symptomatic, parents provide daily data online (RTI symptoms, school/day-care attendance, time off work, health service use, medication), and a research nurse visits to collect clinical examination data and microbiological (nasal and saliva) swabs. Parents are invited to provide symptomatic (at nurse visit, but without nurse assistance) and asymptomatic (alone) swabs on recovery. A review of primary care medical notes will gather medical history, health service utilisation, referral and antibiotic prescribing rates. Feasibility will be assessed using recruitment and retention rates, data completeness; and acceptability by quantitative survey and qualitative interviews. Symptomatic parent and nurse swab pairs will be compared for microbe isolation.
Immunotherapy of Hepatocellular Carcinoma

Field: Medicine (Health Sciences)

Newer immunotherapy agents may break the barrier that tumors create to evade the attack from the immune system. Dendritic cell vaccination has shown encouraging clinical activity and a favorable safety profile in advanced tumor stages. However, optimal cell maturation status, choice of tumor antigens and route of administration have not been established. Single or multiple peptides derived from tumor-associated antigens may also be used for cancer vaccination. Intratumoral delivery of oncolytic viruses expressing immunostimulating cytokines like GM-CSF have produced stimulating clinical results that need further verification. But it is probably T-cell checkpoint modulation with monoclonal antibodies that has attracted the highest expectations. Promising activity has been reported for tremelimumab, a CTLA-4 inhibitor, and a clinical trial testing the PD-1 antibody nivolumab is underway. Future progress will probably come from a better understanding of the mechanisms of cancer-related immunosuppression, improvement in agents and strategies and combination of the available therapeutic tools.
Some Public-key Cryptosystems Over Finite Fields

Field: Computer Science (Physical Sciences)

In this paper, we present two public-key cry ptosystems over finite fields. First of them is based on polynomials. The presented system also considers a digital signature algorithm. Its security is based on the difficulty of finding discrete logarithms over GF(qd+1) with sufficiently large q and d. Is is also examined along with comparison with other polynomial based public-key systems. The other public-key cryptosystem is based on linear codes. McEliece studied the first code-based public-key cryptosystem. We are inspired by McEliece system in the construction of the new system. We examine its security using linear algebra and compare it with the other code-based cryptosystems. Our new cryptosystems are too reliable in terms of security.
Real-Time Measurements of Deposit Formation from Sodium Sulfate-Seeded Flames

Field: Chemistry (Physical Sciences)

Abstract The formation of deposits on substrates immersed in the exhaust gases of a sodium sulfate-seeded flame has been studied in real time using surface Raman scattering and interferometry. Deposits were produced on Pt/10% Rh or Incoloy 800 substrates maintained at 825 K by injecting solid Na2SO4 particles into a CH4/O2/N2 flat-flame burner. For Na2SO4 deposits grown on inert substrates (Pt/10% Rh), the relationship between the sulfate Raman scattering signal and the interferometrically-determined deposit thickness was investigated. The composition of deposits produced from flames of varying stoichiometry was characterized by in situ Raman scattering. Na2CO3 was produced from fuel-rich flames, while Na2SO4 was produced from fuel-lean flames. Mixtures of Na2CO3 and Na2SO4 were obtained from flames of intermediate stoichiometry. For Na2SO4 deposits grown on reactive substrates (Incoloy 800), a rapid reaction occurred between the Na2SO4 deposit and the substrate, producing a salt film containing chromate anions (CrO4 −2).
[Endocarditis associated with atrial and ventricular cardiac pacing leads. Case report].

Field: Medicine (Health Sciences)

The infection of a transvenous lead implanted for cardiac stimulation is a rare, but serious complication. We report observation of a 25-year old man whose Staphylococcus epidermidis sepsis linked to endocarditis was related to atrial and ventricular pacing leads, and was diagnosed after two months of medical treatment. The most important role during the diagnostic process was played by the echocardiographic examination, especially transoesophageal, which revealed the large vegetations on atrial as well as ventricular pacing lead. The diagnosed condition was treated by complete removal of pacing system using open chest surgery and cardiopulmonary pump. After four weeks of vigorous antibiotic treatment, a new DDDR pacing system was implanted, but with epicardial leads.
Prevalence of Overweight and Obesity in Hispanic Preschool Children in San Luis Obispo County, California

Field: Health Professions (Health Sciences)

The purpose of the study was to determine the prevalence of overweight and obese (OW/OB) preschool children in San Luis Obispo County. Preschool children ages 3-5 years were measured for height and weight in 2006 (n = 482) and in 2009/10 combined (n = 559). The CDC BMI calculator for ages 2-20 was used to determine BMI classification. In 2006, 26.4% were OW/OB and by 2009/10, 34.8% were OW/OB. Rates were similar among boys and girls (p = 0.70) and increased significantly over time (p = 0.0070). Caucasian and Hispanic children had similar OW/OB rates in 2006, but by 2009/10 the Hispanic children were 2.7 times more likely to be obese (CI: 1.68, 4.57). Because Hispanic children were more likely to attend Head Start or California State preschools versus private preschools (78.0%, 81.0% and 7.4% respectively), it appears Head Start and California State preschools would be a likely place for interventions directed to meet the needs of Hispanic preschoolers, and may serve to reverse the trend in childhood obesity and address the disparity in weight status among Hispanic preschool aged children.
Phytosanitary risk associated with illegal importation of pest-infested commodities to the South African agricultural sector

Field: Agricultural and Biological Sciences (Life Sciences)

We evaluated the phytosanitary risk associated with illegal importation of pest-infested plant commodities into South Africa. Samples were collected from different South African ports of entry over 8 years (2011 to 2019) and data were analysed descriptively using Statistical Software Package. Pests were frequently detected on commodity species such as Citrus (18.31%), Zea mays (13.22%), Phaseolus vulgaris (12.88%), Musa spp. (9.15%) and Fragaria ananassa (5.08%). The highest number of pests intercepted occurred on fresh fruits (44.06%), followed by grains (26.44%) and vegetables (14.23%). The most intercepted organisms were Callosobruchus rhodesianus (7.79%), Dysmicoccus brevipes (7.11%), Callosobruchus maculates (6.10%) and Phyllosticta citricarpa (4.74%). The majority of intercepted organisms were non-quarantine organisms (70.50%), followed by pests of unknown status (17.28%), quarantine pests (10.84%) and potential quarantine pests (1.35%). Phyllosticta citricarpa, Bactrocera dorsalis, Spodoptera frugiperda and Prostephanus truncatus were the only quarantine pests intercepted in terms of South African regulatory status. The interception was mainly from southern African countries, particularly Mozambique, Zimbabwe and Eswatini. The findings present the level of phytosanitary risk associated with illegal importation and/or non-compliance in regard to plants and plant commodities from different countries through South African ports of entry. Crop production, biodiversity, food security, existing export markets, and access to new export markets could be threatened as importing countries may impose stringent phytosanitary measures to limit the chances of introduction and establishment of quarantine pests into their territories. Significance Illegal importation of plant commodities may lead to the introduction, establishment and spread of pests that are of quarantine significance to South Africa. Introduction of pest species such as Phyllosticta citricarpa, Bactrocera dorsalis, Spodoptera frugiperda and Prostephanus truncatus into South Africa could result in undesirable impacts on the ecosystem, agriculture, biodiversity and economy of the country. Access to new export markets of plant commodities could be threatened as importing countries may impose stringent phytosanitary measures to limit the chances of introduction and establishment of these quarantine pests into their territories.
Esterase, Glutathione S-Transferase and NADPH-Cytochrome P450 Reductase Activity Evaluation in Cacopsylla pyri L. (Hemiptera: Psyllidae) Individual Adults

Field: Agricultural and Biological Sciences (Life Sciences)

Cacopsylla pyri (L.) (Hemiptera: Psyllidae) is a key pest of pear orchards in Spain. The large number of insecticide treatments necessary for control may be an important contributor to the emergence of resistance. Laboratory toxicity and biochemical assays are necessary to validate the existence of insecticide resistance and establish the underlying mechanisms. All the methodologies developed to evaluate enzyme activity in C. pyri to date have incorporated “pools” of adults to detect minimum activity ranges. In this study, we determined the optimal working conditions for evaluation of the activities of esterase, glutathione S-transferase and NADPH-cytochrome P450 reductase in individual insects via colorimetric methods using a microplate reader. The main factors affecting enzymatic analysis activity, such as enzyme source and substrate concentration, filter wavelength, buffer pH, reaction time and additives, were evaluated for optimization. Determining the frequency of resistant individuals within a population could be used as an indicator for the evolution of insecticide resistance over time. Two laboratory strains, one of them selected with cypermethrin, and two field populations were analyzed for this purpose. The data obtained revealed high values and great variation in the activity ranges of esterase (EST) in the insecticide-selected population as well as in the field populations validating the applied methodology.
Life-history variation in the annual arable weed Diplotaxis erucoides (Cruciferae)

Field: Agricultural and Biological Sciences (Life Sciences)

Variation in life-history traits such as emergence, survival, time of flowering, and fecundity were studied in Diplotaxis erucoides, a mediterranean winter annual weed, by analyzing cohorts that emerged in autumn, early spring, and spring. The response of the plants to the environment, as reflected by plant architecture and pattern of biomass allocation, was also studied. Seedlings that germinate in autumn produced from 3 to 10 times more seeds than those that germinated in spring. The main factor affecting the number of seeds produced appears to be the life-span. Reduction of the growing period led to a decrease in both number and length of modular units, which resulted in decreased numbers of leaves, flowers, and fruits of each module. In semelparous D. erucoides plants, differences in the pattern of biomass allocation to reproduction are related to plant size. Our field data indicate that an increase of reproductive effort with size occurs in small individuals; however, a decrease occurs for vegetative biomass greater than 2 g and less than 5 g. Little variation in reproductive effort occurs when vegetative biomass is greater than 5 g. From a strategic point of view, size-dependent variation of reproductive effort in D. erucoides can be interpreted as good tactics to favour a higher proportion of resources devoted to reproduction in small individuals, thus ensuring some offspring. However, structural, developmental, and physiological constraints lead to stabilization or even a decrease in reproductive effort above a certain threshold size, when production of offspring is already ensured. Key words: phenotypic plasticity, plant architecture, biomass allocation, Diplotaxis erucoides.
