Influence of Test Configuration on Bond Strength of GFRP Bars
Authors: Januš Ondřej , Girgle Frantisek , Kostiha Vojtech , Stepanek Petr , Sulak Pavel
Published: June 2019

It is well-known that test configuration affects bond behaviour of steel reinforcement, but this effect has not yet been sufficiently quantified when using FRP reinforcement. This paper presents partial results from an ongoing experimental programme that deals with the bond strength of GFRP bars with concrete, with regards to the effect of the surface treatment of the rebars and test configuration. A modified beam test is presented in this study along with a pull-out test with an eccentric bar placement. The bond strength of GFRP reinforcement with sand-coated treatment using silica sand and ribbed type with milled ribs was tested. The sand-coated bars exhibit different bond behaviour compared to the ribbed ones due to different forces transfer from the reinforcement to the concrete. Thickness of the concrete cover layer also has a significant effect on the bond behaviour of the reinforcement.
Adaptive Estimation of the In Situ Characteristic Concrete Strength
Authors: Derechennik Stanislav S. , Tur Viktar V.
Published: June 2019

For calculation of existing concrete structures on the basis of the partial factor format, the main representative value is the actual in-situ characteristic value of the concrete strength. When samples are tested, the concrete in-situ strength of the structure shall be determined, statistically if possible, from the test results. In accordance with EN 1990 the 5% percentile value is calculated on the basis of a unilaterally limited constant confidence level. It was found the in some case, estimation of the in-situ characteristic concrete strength taking a constant confidence level does not allow to adequately assess the reliability of the existing structures. A new estimator based on non-parametric statistical method was proposed for estimating of the in-situ characteristic concrete strength with a given arbitrary confidence level. The procedure that was proposed allows one to re-establish of the estimator pdf even with a very limited sample size. It is established, that the choice of the confidence level of the estimator should be based on the average reliability of the structure.

Authors: Sucharda Oldrich , Bilek Vlastimil , Mateckova Pavlina , Pazdera Lubos
Published: June 2019

Advances in technology and sustainability requirements create substantial demand for material research. In construction industry, possibilities of innovation of concrete are opened by using recipes based on new activation methods, where alkaline activated composites can be included. This article focuses on this area where the results of the recipe verified under industrial conditions are presented, and the way of processing is significantly different from the laboratory conditions. The aim of the article is to present the material properties and differences of alkali activated specimens that are compared with series of common concrete material properties based on composition from the same aggregate material base. It was found that the most significant differences are the modulus of elasticity. In both of the recipes, the same design cube compressive strength is used. The article presented also experiment and nonlinear analysis of the alkali-activated beam without shear reinforcement, which was used to study the mechanism of damage and collapse of AAM beam. Nonlinear analysis was used thanks to complex knowledge of material properties. Numerical modelling uses the ATENA software. Test of small structural element is complemented by an advanced crack detection diagnosis with the use of acoustic emission.

Use of high strength concrete require reliable predictions of correlations of compressive strength with tensile strength or splitting strength. Analysis of correlation between tensile strength of concrete and compressive strength, based on experimental results, is shown in this paper. It is proposed new simple correlation. Regression analysis that use, is based on the results of the experimental researches of compressive strength and splitting tensile strength, at specimens of high strength concrete. Comparative analysis of test results, gained for high strength concrete and normal strength concrete is performed. Analysis comprises the results of the experimental research of deep beams subjected to shear. Stresses measured on surfaces of high strength concrete beams subjected to shear and level of stresses that induce inclined cracks in concrete are applied. Relationship between concrete compressive strength and shear cracking stresses is studied, too. Experimental research was done at pairs of the beams made of concrete with high compressive strength and normal compressive strength. Estimation of validation of relations prescribed by the design codes for high strength concrete has performed.

Authors: Bulíková Lucia , Kresta František
Published: June 2019

Power plants use new technologies to reduce emissions limits. Denitrification is a process that leads to the reduction of NOx in the flue gas. However, in this process, the ammonia or urea is bound to the fly ash and it may adversely affect the properties of this secondary material and it influences its practical utilisation. In this contribution research of siliceous fly ash after denitrification by SNCR in the field of hydraulic road binders for soil treatment is described. In the last time a number of new hydraulic road binders with fly ash as their component have been prepared and used. Fly ash is used due to its pozzolan properties (siliceous FA) or hydraulic properties (calcareous FA) and low purchase price. In described case, fly ash after denitrification was used in mixture with Portland cement and cement kiln dust in ratio 60/30/10. The prepared mixture showed good properties and fulfilled requirements of the EN 13282-2: Normal hardening hydraulic road binders. These binders have to comply with the requirements determined by cement standards.

[Waders and seabirds (Charadriiformes) nesting along the north-eastern Adriatic coastline (Veneto and Friuli-Venezia Giulia) in 2008-2014: abundance, trends and major conservation issues]
Authors: Scarton Francesco , Verza Emiliano , Guzzon Carlo , Utmar Paolo , Sgorlon Giacomo , Valle Roberto
Published: June 2019

[In 2008-2014 wader and seabird nesting pairs were censused along the 220-km long coastline of the NE Adriatic Sea, in the Veneto and Friuli-Venezia Giulia regions (NE Italy). Fourteen species were regularly breeding, with an annual mean of 20,610 pairs (±1553, 1 SD). The most abundant species was the Yellow-legged Gull (about 13,400 pairs on average, 65% of the whole population of the study area), followed by the Common Tern (1670 pairs, 8.1%) and Common Redshank (1525 pairs, 7.4%). The whole population of waders and seabirds increased with an annual rate, estimated with the TRIM software, of +0.8%, with a greater increase (+4.3%) if the Yellow-legged Gull was not included. Twelve species were stable or increasing; only the yellow-legged gull (-1%) and the common redshank (-2.4%) were decreasing. The populations of several species exceed 10% of those estimated for the whole of Italy; those of the Eurasian Oystercatcher, Common Redshank and Sandwich Tern are among the most important in the whole Mediterranean. On average, about 8860 pairs (43%) nest in the Venice lagoon, 6,400 pairs (31%) in the Po Delta, 5100 pairs (25%) in the Friuli-Venezia Giulia lagoons. Among nesting habitats, semi-natural (such as the fish farms) and man-made sites (dredge islands) make each year about 70% of the nesting pairs. Saltmarsh islets host large numbers of Common Redshank and Sandwich Tern, while along the beach zone the only abundant species are the Yellow-legged Gull and the Eurasian Oystercatcher. The major conservation threats observed in the study area were the erosion of littoral islands, the uncontrolled occurrence of sunbathers along the beaches, the vegetation overgrowth at dredge islands, the increasing frequency of saltmarsh submersion by high tides, the strong fluctuations of water levels inside the fish farms.]

Los dos memoriales de escrituras de fray Bernardo Cardillo Villalpando (Santa María de Monfero, 1616)
Authors: Suárez González Ana
Published: June 2019

Ninguna de las obras de Fray Bernardo Cardillo Villalpando (1570-1637), conocido cro-nista cisterciense que visitó numerosas casas de su Orden, llegó a la imprenta. Por ello, la mayor parte de su producción ha desaparecido. Entre los pocos textos que han pervivido se encuentran los dedica-dos a Santa María de Monfero (A Coruña), recientemente identificados. Es el caso de los dos "memo-riales" de escrituras reales y pontificias de la abadía, redactados en 1616 y dispuestos al final del llamado "Tumbo viejo" que hoy guarda el Archivo Municipal de A Coruña. La recuperación, edición y estudio de ambos repertorios permite no sólo un acercamiento al archivo del monasterio a comien-zos del setecientos y al devenir de su fondo, también conocer y evaluar el estilo, método y resultados de la tarea del erudito. La comparación entre la información que ofrece Fr. Bernardo y la que, cuatro siglos después, podemos extraer de los pergaminos supervivientes citados en sus memoriales, mues-tra, por una parte, la sólida formación del autor para abordar el estudio del "patrimonio documental" y, por otra, el rigor con el que llevó a cabo su trabajo.)
Sound change and coarticulatory variability involving English /ɹ/
Authors: Smith Bridget J. , Mielke Jeff , Magloughlin Lyra , Wilbanks Eric
Published: June 2019

English /ɹ/ is known to exhibit covert variability, with tongue postures ranging from bunched to retroflex, as well as various degrees of lip protrusion and compression. Because of its articulatory variability, /ɹ/ is often a focal point for investigating the role of individual variation in change. In the studies reported here, we examine the coarticulatory effects of alveolar obstruents with /ɹ/, presenting data from a collection of sociolinguistic interviews involving 162 English speakers from Raleigh, North Carolina, and a pilot corpus of ultrasound and lip video from 29 additional talkers. These studies reveal a mixture of assimilatory and coarticulatory patterns. For the sound changes in progress (/tɹ/ and /dɹ/ affrication, and /stɹ/ retraction), we find increases over apparent time, but no effect of covert variability in our laboratory data, consisting mostly of younger talkers. When a sound change has already become phonologized to a new phonemic target with a correspondingly different articulatory target, the original variability is obscured. In comparison, post-lexical coarticulation of word-final /s z/ before a word-initial /ɹ/ more closely resembles /s z/ in tongue posture, with an effect of anticipatory lip-rounding that introduces a low-mid frequency spectral peak during the sibilant interval, and greater reduction in the frequency of this peak for talkers who transition more rapidly to the /ɹ/. In order to uncover the role of covert variability in a sound change, we must look to sounds that exhibit synchronically stable articulatory variability.

A Detailed Neuroscientific Framework for the Multiple Intelligences: Describing the Neural Components for Specific Skill Units within Each Intelligence
Authors: Shearer C. Branton
Published: June 2019

The concept of intelligence has been debated since introduction of IQ tests in the early 1900s. Numerous alternatives to unitary intelligence have achieved limited acceptance and IQ remains the predominant theoretical basis for schooling. Multiple intelligences theory (Gardner, 1983), despite criticism it lacks experimental validity, has had sustained interest by educators worldwide as a means of personalizing instruction and curriculum. The neuroscientific evidence for the intelligences has not been updated since 1983. This investigation reviewed 417 neuroscientific studies examining neural correlates for skill units within seven intelligences. Neural activation patterns demonstrate each skill unit has its own unique neural underpinnings as well as neural features shared with other skill units within its designated intelligence. These patterns of commonality and uniqueness provide richly detailed neural architectures in support of MI theory as a scientific model of human intelligence. This conclusion is supported by four previous studies revealing extensive neural evidence that MI theory distinguishes among ability groups and several cognitive qualities (Shearer and Karanian, 2017). The emerging field of educational cognitive neuroscience strives to bridge the gap between laboratory findings and classroom instruction. MI theory aligns with advances in understanding how the mind and brain interact providing a practical interface between the art of teaching and neuroscience. A neuroscientific model of the multiple intelligences brings us closer to the goal of personalizing education by understanding the unique neuro-cognitive profiles of all students. These findings, coupled with advanced technologies, point the way forward to bring MI-inspired education to all students.
Zinc dichloride. Determination in workplace air
Authors: Surgiewicz Jolanta
Published: June 2019

Zinc dichloride is very soluble in water. It is used in galvanic processes, for wood impregna-tion, in the textile industry, in organic synthesis and for the production of explosives, for example smoke candles. Zinc dichloride has an irritating, corrosive and damaging effect on the eyes, mucous membranes of the airways, causes severe pneumonia, skin burns and systemic poisoning. Maximum allowable concentration value (MAC) for the inhalable fraction of zinc dichloride in Poland is 1 mg/m3 and the short-term exposure limit value (STEL) is 2 mg/m3. The aim of the study was to amend standard PN-Z-04367:2008 and to develop a method for determining zinc dichloride in workplace air in the range from 1/10 to 2 MAC values. The developed method of determination is based on taking a sample of air into two membrane filters, washing out zinc dichloride from the filters with deionized water and de-termining that compound as zinc by atomic absorption spectrometry (F-AAS) with atomiza-tion in air-acetylene flame. The method allows determination of zinc dichloride in the work-place air in the concentration range of 0.07–2.17 mg/m3 (for an air sample with a volume of 720 L, which corresponds to 0.1–2.2 of the MAC value. The method is characterized by good precision and accuracy and meets the requirements of European Standard PN-EN 482 for procedures for the determination of chemical substances. The method for the determination of zinc dichloride has been recorded in the form of an analytical procedure (see Appendix). This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.
Calcium hydroxid. Determination in workplace air
Authors: Surgiewicz Jolanta
Published: June 2019

Calcium hydroxide is a white color solid. It is used in construction, chemical industry, water purification and wastewater treatment, flue gas desulphurization. Calcium hydroxide causes serious damage to the eyes, irritates the skin and it can cause after-launch respiratory irritation. Maximum allowable concentration value (MAC) for calcium hydroxide in the work environment in Poland, for the inhalable and respirable fraction is 2 mg/m3 (STEL is 6 mg/m3) and 1 mg/m3 (STEL is 4 mg/m3), respectively. The aim of the study was to develop a method for determining the concentration of calcium hydroxide present in the inhalable and respirable fraction in the workplaces atmosphere, in the range from 1/10 to 2 MAC values in accordance with the requirements of European Standard PN-EN 482. The developed method is based on collecting, stopping calcium hydroxide (contained in the inhalable and the respirable fraction) on membrane filters, mineralizing filters with concentrated nitric acid and determining calcium of the resulted solution by atomic absorption spectrometry with atomization in acetylene-air flame (F-AAS). The described method allows the determination of calcium in workplace air concentrations in the range of 0.50–20.00 µg/ml. The calibration curve characterized by a high value of the correlation coefficient: R2 = 1.0000. The limit of detection (LOD) is 0.1 ng/ml and the limit of quantification (LOQ) is 0.3 ng/ml. The determined coefficient of recovery is 1.00. An analytical method allows the determination of the concentration of the calcium hydroxide present in the workplace air in the inhalable fraction in the concentration range of 0.10–4.11 mg/m3 (sample air volume 720 L) and in the reparable fraction in the concentration range 0.07–2.70 mg/m3 (for a sample air volume of 684 L), which represents 0.05–2.1 MAC value for the inhalable fraction and 0.07–2.7 MAC value for the respirable fraction. The method has good precision and accuracy and meets the requirements of European Standard PN-EN 482 for procedures for determining chemical agents. The method for determining calcium hydroxide has been recorded in the form of an analytical procedure (see Appendix). This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.

Authors: Abrita Ana Paula Caserta Tencatt , Abrita Mateus Boldrine
Published: June 2019

Este estudo tem por objetivo discutir aspectos psicológicos, biológicos e socioeconômicos da hanseníase, discutindo o impacto que estes podem vir a gerar no psiquismo do sujeito. A amostra foi composta por 5 (cinco) indivíduos diagnosticados com hanseníase em fase de tratamento poliquimioterápico no ambulatório de dermatologia ‘Dr. Günter Hans’ do Hospital Universitário ‘Maria Aparecida Pedrossian’ da Universidade Federal de Mato Grosso do Sul. O instrumento de coleta de dados utilizado foi a entrevista individual semiestruturada e os pressupostos da psicanálise para interpretação dos mesmos. A pesquisa foi realizada na Clínica Ayrakie, que fornece espaço para as atividades do ABRAPSI/IDEA Brasil, na cidade de Campo Grande/MS. Com base na análise dos dados das entrevistas, concluiu-se que a forma pela qual o sujeito lidará com o adoecer é particular. No entanto, questões como mudanças estéticas, dificuldades laborais e o preconceito estão presentes nos discursos como pontos geradores de sofrimento. Desta forma, ressalta-se a necessidade de uma ampliação do tratamento de hanseníase, para além do âmbito biológico, contemplando aspectos socioeconômicos, psicológicos e investimento em políticas públicas. A partir da perspectiva interdisciplinar, é possível elaborar alternativas que possam efetivamente ajudar o paciente, atuando na doença, combatendo o preconceito e devolvendo a dignidade humana.
Cursos de graduação em ciências ambientais no Brasil: uma análise curricular comparativa
Authors: Viesba Letícia Moreira , Vietti Bitencourt Ana Luisa , Neiman Zysman
Published: June 2019

A ciência ambiental é relativamente recente no cenário epistemológico e metodológico das ciências consideradas tradicionais (Exatas, Humanas e da Natureza), assim como os cursos de graduação que levam essa nomenclatura. Pela recente atuação desses cursos no Brasil, e a ausência de Diretrizes Básicas Curriculares (DBC) referente à esse curso, esse trabalho objetiva uma analise comparativa curricular dos cursos de Ciências Ambientais no Brasil. As disciplinas, suas cargas horárias e abordagens foram comparadas entre as universidades e nas diferentes áreas de conhecimento segundo o CNPq. Observou-se que a carga horária variou entre as dez universidades que oferecem o curso, tanto a carga horária total, desde 4012 horas (Unifesp) a 2400 (UFMG), quanto às cargas horárias das disciplinas nas grandes áreas, mostrando as diferenças de abordagens das universidades. Com essa análise pode-se entender que apesar da ausência das DBC, há uma semelhança quanto às grandes áreas do conhecimento abordadas, e ao perfil do egresso que procura ter uma formação interdisciplinar com abordagens transdisciplinares, e as diferenças entre as universidades também se mostraram importantes de modo que mostrem suas singularidades e focos seguindo justamente a proposta de flexibilização das Lei de Diretrizes e Bases da Educação Nacional (LDB).
Cheminement et difficultés analytiques en méthodologie de la théorisation enracinée : expérience de deux doctorantes
Authors: Caty Marie-Ève , Hébert Maude
Published: June 2019

Les difficultés analytiques de la méthodologie de la théorisation enracinée (MTE) sont rarement abordées dans les écrits scientifiques. Comment mettre en oeuvre la MTE? Quelles sont les difficultés analytiques de la MTE rencontrées par les chercheurs novices? Cet article aborde des moments critiques vécus par les deux auteures au cours de l’analyse de leurs données de recherche doctorale suivant les principes de la MTE. L’objectif est de mettre en lumière des difficultés qui surviennent pour une majorité de chercheurs novices dans la réalisation d’une recherche qualitative employant un devis MTE ainsi que d’offrir des conseils notamment en lien avec la gestion de la panoplie de données, la saturation des données et la démarche itérative. Des exemples précis tirés du projet de doctorat des deux auteures sont partagés. Il en ressort que l’encadrement du directeur de thèse est primordial dans le cheminement analytique. Ceci rappelle que le mentorat est un élément important dans l’apprentissage de la MTE.

Importance of the Toxicological Tests in the Application and Safety of Ozone Therapy
Authors: Menendez-Cepero Silvia , Zamora Zullyt , Hernandez Frank
Published: June 2019

Until today, there is not any official registry of the different routes of systemic ozone therapy. With the aim to prove the safety of this therapy, several ways of ozone (O3) applications were evaluated, such as rectal insufflation (RI), major autohemotherapy (M-AHT) and intraperitoneal application (IP). For RI, some toxicological tests were performed such as: acute, sub-chronic, mutagenic (bone marrow chromosomic aberrations and micronucleus), teratogenic  and irritation studies (at 40 mg/L and 10 mL during 15 days). For M-AHT, acute toxicological (in rats with 21, 47 and 64 mg/L and a volume of 2 mL with daily evaluation up to 15 days) and mutagenic (chromosomal aberration analysis, micronucleus assay and sister chromatid exchange test) studies were performed. For IP application, subchronic (O3 was administered during 15 days in mice at concentrations of 11, 29 and 35 mg/L and volumes of 80 mL/kg) and genotoxic (cytotoxic and clastogenic activity) studies were evaluated. All the toxicological studies performed for the O3 RI fulfilled the requirements established for an official registry (no deleterious effects were observed). However, more toxicological studies must be done with respect to M-AHT and IP O3 applications in order to prove the complete safety of these ways.

Published: June 2019

Purpose.
Alveolar osteitis is the most common post-odontectomy complication. Although blood clot disintegration is known to be the cause of the condition, an agreement is lacking regarding a treatment of choice. The aim of the current study therefore was to evaluate major autohemotherapy as one treatment method.

Patients and Methods.
A total of 183 patients were categorized into 4 groups (I, II, III, and IV) according to pain severity (mild, moderate, severe, or agonizing, respectively). Major autohemotherapy was performed for all patients by withdrawing 225mL of patient's blood and mixing them with 225mL of Oxygen-Ozone gas (where Ozone concentration was 50µg/mL gas)

Results and Discussion.
Despite AHT was a high-potency curative treatment for groups I and II, it was palliative for group IV. For group III, it oscillated between being a curative or a palliative treatment with a statistically insignificant difference.

Conclusion.
AHT might be a recommended treatment for AO

Published: June 2019

The Hepatitis B (HVB) is one of the most common infectious diseases in the world, it’s wide geographical distribution is a health problem, especially on the African continent, with prevalence rate of 6.1% in the adult population. Current treatment requires prolonged therapy (most cases for the rest of life) with the aim of stopping viral replication, maintaining immunological stability, preventing progression of liver disease and the most feared complications such as cirrhosis and hepatic cancer
There are multiple references that point to ozone therapy as an alternative in the treatment of Hepatitis B, because of the known and demonstrated antimicrobial and immunomodulatory properties. With these premises, we performed the present clinical study that included 28 patients with positive diagnosis of chronic Hepatitis B, surface antigen (HVBs Ag) positive, antibodies against surface antigen (HVBs) negative, viral load (HVB DNA ) and transaminaseselevated. These patients with 1 year of evolution and antiviral treatment were treated with Major Autohemotherapy with protocol of 15 sessions and maintenance every 15 days to 50 mcg of concentration, initial dose of 4,000 mcg / ml up to 12,000 mcg /ml
We indicate Ag HVBs, Ac HVBs, HVB Viral Loading and transaminases before starting treatment at 15 days of completion and quarterly until the year. The results showed negativization of the surface antigen, antibody positivity against the surface antigen, significant decrease of viral load to undetectable values and normal values of the transaminases demonstrating the functional recovery of the disease associated with favorable immunological response providing a better quality of patients' lives.
Key words: Hepatitis B, Transaminases, Ozone therapy, Major Autohemotherapy, Surface antigen, Surface Antigen Antibody.

Published: June 2019

Introduction.
Reading reference ozone books from Dra. Menendez, Dra. Viebhan, Dra. Borrelli and Dr. Bocci, proper timing for mixing ozone in blood during autohemotherapy is not calculated in a scientific way, having only an estimation of it based on changes in the blood color, more related to oxygen absorption than on ozone itself.

Material and methods.
We decided to reproduce a reduced model of great autohemotherapy or recently renamed as systemic indirect endovenous ozonotherapy (SIEVO) by the World Federation of Ozone Therapy – WFOT, using syringes to simplify the experiment. Our model consisted of a 20 mL syringe filled with 10 mL of blood withdrawn from healthy volunteers and mixed it gently but in controlled way with 10 mL medical ozone at different concentrations; after 5 and 8 seconds, the remaining gas was analyzed by an spectrophotometer based ozone detector to check the amount of ozone. Data were analyzed using a linear regression model.

Results.
Results show that even for 60 mcgr/mL ozone concentration, 8 seconds is enough to let all ozone absorbed in blood.

Discussion and Conclusions.
The experiment shows how quick ozone reacts with blood and claims for a trial with real SIEVO devices to achieve a real timing.
Scc2 counteracts a Wapl-independent mechanism that releases cohesin from chromosomes during G1

Cohesin’s association with chromosomes is determined by loading dependent on the Scc2/4 complex and release due to Wapl. We show here that Scc2 also actively maintains cohesin on chromosomes during G1 in S. cerevisiae cells. It does so by blocking a Wapl-independent release reaction that requires opening the cohesin ring at its Smc3/Scc1 interface as well as the D loop of Smc1’s ATPase. The Wapl-independent release mechanism is switched off as cells activate Cdk1 and enter G2/M and cannot be turned back on without cohesin’s dissociation from chromosomes. The latter phenomenon enabled us to show that in the absence of release mechanisms, cohesin rings that have already captured DNA in a Scc2-dependent manner before replication no longer require Scc2 to capture sister DNAs during S phase.

Olfactory associative learning in Drosophila is mediated by synaptic plasticity between the Kenyon cells of the mushroom body and their output neurons. Both Kenyon cells and their inputs from projection neurons are cholinergic, yet little is known about the physiological function of muscarinic acetylcholine receptors in learning in adult flies. Here, we show that aversive olfactory learning in adult flies requires type A muscarinic acetylcholine receptors (mAChR-A), particularly in the gamma subtype of Kenyon cells. mAChR-A inhibits odor responses and is localized in Kenyon cell dendrites. Moreover, mAChR-A knockdown impairs the learning-associated depression of odor responses in a mushroom body output neuron. Our results suggest that mAChR-A function in Kenyon cell dendrites is required for synaptic plasticity between Kenyon cells and their output neurons.

Published: June 2019

The observed dynamics of infectious diseases are driven by processes across multiple scales. Here we focus on two: within-host, that is, how an infection progresses inside a single individual (for instance viral and immune dynamics), and between-host, that is, how the infection is transmitted between multiple individuals of a host population. The dynamics of each of these may be influenced by the other, particularly across evolutionary time. Thus understanding each of these scales, and the links between them, is necessary for a holistic understanding of the spread of infectious diseases. One approach to combining these scales is through mathematical modeling. We conducted a systematic review of the published literature on multi-scale mathematical models of disease transmission (as defined by combining within-host and between-host scales) to determine the extent to which mathematical models are being used to understand across-scale transmission, and the extent to which these models are being confronted with data. Following the PRISMA guidelines for systematic reviews, we identified 24 of 197 qualifying papers across 30 years that include both linked models at the within and between host scales and that used data to parameterize/calibrate models. We find that the approach that incorporates both modeling with data is under-utilized, if increasing. This highlights the need for better communication and collaboration between modelers and empiricists to build well-calibrated models that both improve understanding and may be used for prediction.
Effect of insecticide formulation and adjuvant combination on agricultural spray drift

Published: June 2019

Loss of crop protection products when agricultural spray applications drift has economic and ecological consequences. Modification of the spray solution through tank additives and product formulation is an important drift reduction strategy that could mitigate these effects, but has been studied less than most other strategies. Therefore, an experimental field study was conducted to evaluate spray drift resulting from agricultural ground applications of an insecticide formulated as a suspension concentrate (SC) and as a wettable powder (WP), with and without two adjuvants. Droplet sizes were also measured in a wind tunnel to determine if indirect methods could be substituted for field experimentation to quantify spray drift from these technologies. Results suggest that spray drift was reduced by 37% when comparing the SC to the WP formulation. As much as 63% drift reduction was achieved by incorporating certain spray adjuvants, but this depended on the formulation/adjuvant combination. The wind tunnel data for droplet spectra showed strong agreement with field deposition trends, suggesting that droplet statistics could be used to estimate drift reduction of spray solutions. These findings can be used to develop a classification scheme for formulated products and tank additives based on their potential for reducing spray drift.
A revision of Blechnum vulcanicum (Blume) Kuhn and related taxa (Blechnaceae) in Malesia and Oceania
Authors: Chambers T Carrick , Wilson Peter G
Published: June 2019

The species included in the Blechnum vulcanicum group are all characterised by the presence of unique, minute, surface outgrowths on various aerial parts of a plant; these have previously in error been described as short hairs. However, these so-called ‘hairs’ are distinctive and consist of about 4 to 7 cells in a linear arrangement. The species of Blechnum that have this feature are here recognised as a new Section, Blechnum sect. Pilosa. The species Blechnum vulcanicum (Blume) Kuhn has been widely cited in taxonomic, floristic and ecological studies for Malesia, Australasia and Oceania, but shows much variation across this wide geographic range. The present study rejects this broad view and recognises a total of 14 species in this group. This includes four new species (Blechnum aequabile, B. basipilosum, B. humile and B. megavulcanicum), and three new combinations (Blechnum deltoides, B. feani, and B. tovii).
A Revised Checklist of the Moss Flora of the Australian Wet Tropics
Authors: Cairns Andi , Meagher David , Ramsay Helen
Published: June 2019

The Australian Wet Tropics bioregion is a hotspot for bryophyte diversity. In 2004, 397 moss taxa were known from the bioregion, since when extensive field work and taxonomic studies have added many taxa to the Wet Tropics bryophyte flora, while revisions and nomenclatural changes have reduced the number previously published. In this paper we summarise the additions to our knowledge of Wet Tropics bryophytes, and accept 410 moss taxa from the bioregion, including 170 genera in 60 families. We add 55 taxa to the flora, and 24 are rejected on the basis of false records or misidentifications, or because the records were found to be outside the Wet Tropics bioregion. Records of 14 taxa from the bioregion are considered uncertain, and 6 taxa previously considered doubtful for the bioregion are confirmed. A number of records including Holomitrium cylindraceum and Taxithelium lindbergii are reported as new to Australia.
