Reinstatement of rhipicephalus (Boophilus) australis (Acari: Ixodidae) with redescription of the adult and larval stages

Rhipicephalus australis Fuller, the Australian cattle tick, is reinstated and the adults and larvae redescribed from material collected in Australia. This long ignored boophilid was previously known as R. microplus Canestrini for specimens reported in Australia and New Caledonia. The adults of R. australis are easily recognized by a combination of characters, such as the ventro-medial spurs in the palpal segments of the male, and the abundant, plumose, pale white setae on the dorsum of the female. Other details, such as coxal and adanal shields are more variable among different populations and may lead to incorrect determinations. Larvae of R. australis are clearly smaller than those of R. microplus. The use of principal components analysis on body measurements leads to a clear separation of larvae of both taxa. A phylogenetic analysis based on 12S- and 16S-rDNA gene sequences supports the conspecificity of the neotype material on which the reinstatement of the species is proposed, and of the specimens used for previous interspecific crosses. R. australis is now known to be present in Australia, New Caledonia, the island of Borneo, Philippines, Sumatra, Java, New Guinea, Cambodia, and Tahiti. Both R. microplus and R. australis coexist in some countries in southeastern Asia. Given the extreme importance of these ticks for the cattle industry, field data on their distribution in the region are required to know the actual range of these species and to understand the evolution of the group.Fil: Estrada Peña, Agustín.

Mejora continua en el procedimiento de otorgamiento del certificado de habilitación técnica de terminales terrestres, distrito La Victoria, 2019

En la presente investigación, se determinó como objetivo general si el MTC cumple con aplicar la mejora continua en el procedimiento de otorgamiento del certificado de habilitación técnica de terminalesterrestres, distrito La Victoria, 2019. En la mejora continua se aplicó las dimensiones planificación, hacer, verificar y actuar, sustentadas en la teoría de Deming, conocida como el ciclo PDCA cuyo principio está orientada que, si no se puede medir, tampoco se puede gestionar, siendo utilizada en la mayoría de las organizaciones que ofrecen servicios. La investigación consistió en un enfoque cualitativo, empleando la teoría fundamentada, que procede de datos recopilados en forma sistemática basándose en datos reales, abarcó la participación de ocho profesionales y especialistas en temas de transporte terrestre designados por el MTC, así como inspección a diez terminales terrestres ubicados en el mencionado distrito. Los instrumentos utilizados fueron guías de entrevista y ficha de observación, validados por juicios de expertos, donde establecieron que existe suficiencia. De acuerdo a la triangulación de los datos, los resultados fueron los siguientes: carencia de manuales de procedimientos, para otorgar el certificado de habilitación técnica, falta de regulación de la normativa RNAT, para reevaluar la aplicación de la declaración jurada y definir las áreas perimétricas de las instalaciones de los locales, antes de otorgar el certificado de habilitación, en la oficina de atención al ciudadano no existe personal idóneo designado por unidad orgánica DGATR, a fin de guiar a usuarios en forma presencial o virtual, así también, las reubicaciones y renovaciones de dichos terminales, no están definidos en la citada normativa y como resultado recogido de las inspecciones realizadas la mayoría de terminales incumplen la normativa, por cuanto fueron habilitados con vigencia indefinida

Competição e Concentração entre os Bancos Brasileiros

This paper analysis the relationship between market structure and competitiveness in the Brazilian banking industry. First, it quantifies competitiveness by using the statistic-H proposed by Panzar & Rosse and evaluates its relationship with several concentration statistics: Herfindahl-Hirschman, Concentration Ratio, Hall-Tideman and Theil. The concentration indexes lead concentration in CR10 (assets and deposits), while the concentration of credit reduces. There is a monopolistic competition among Brazilian banks. The relationship between competitiveness and concentration is negative and significant.Competição, Concentração, Bancos Brasileiros

A community approach to the Neotropical ticks-hosts interactions

The relationships between ticks and hosts are relevant to capture the ecological background driving the evolution of these parasites. We used a set of 4,764 records of ticks of the genera Amblyomma, Ixodes, and Haemaphysalis and their hosts in the Neotropics to approach the tick-host relationships using a network-based construct. The network identified 9 clusters of interacting hosts and ticks partially connected by 22 tick species that switch their host range according to their life cycle stage. These links among clusters do not confer an extra resilience to the network following removal of hosts and subsequent cascade extinctions of ticks: the robustness of the network slightly changed when these inter-clusters links are considered. Phylogenetic clustering of ticks to hosts at cluster level was not significant (p > 0.15) but if examined individually 63 tick species/stages (59%) displayed such clustering, suggesting that their hosts have a related phylogenetic background. We interpreted these results under an ecological perspective in which ticks could track its environmental niche associating to vertebrates that would maximize tick survival under the range of abiotic traits. We encourage these integrated analyses to capture the patterns of circulation of tick-transmitted pathogens, a topic still unaddressed in the Neotropical region.EEA RafaelaFil: Estrada-Peña, Agustin.

Retrieving the thermal diffusivity and effusivity of solids from the same frequency scan using the front photopyroelectric technique

The photopyroelectric (PPE) technique in the front configuration consists in illuminating one surface of a pyroelectric slab while the other surface is in contact with the test sample. This method has been widely used to measure the thermal effusivity of liquids. Recently, it has been extended to measure the thermal effusivity of solids, by taking into account the influence of the coupling fluid layer used to guarantee the thermal contact. In both cases, the sample (liquid or solid) must be very thick. In this work, we propose a classical frequency scan of a thin sample slab to retrieve the thermal diffusivity and effusivity simultaneously. We use the amplitude and the phase of the front PPE signal, which depend on four parameters: the sample diffusivity and effusivity, the coupling fluid thickness and the coefficient of heat losses. It is demonstrated that the four quantities are not correlated. PPE measurements performed on a set of calibrated solids confirm the ability of the method to obtain the thermal diffusivity and effusivity of solids accurately.This work has been supported by Ministerio de Economía y Competitividad, (DPI2016-77719-R, AEI/FEDER, UE), by Gobierno Vasco (KK-2016/00027) and by Universidad del País Vasco UPV/EHU (GIU16/33)

Paper-Based Analytical Devices for Accurate Assessment of Transferrin Saturation in Diagnosed Clinical Samples from Ischemic Stroke Patients

For the first time, a paper-based analytical device (PAD) was developed for the assessment of transferrin saturation (TSAT), which is defined as the ratio between iron bound to transferrin (Tf) and the total iron-binding capacity (TIBC) of Tf. Both parameters were simultaneously measured on the same PAD using ferrozine as a chromophore and a smartphone as the color reader. To this end, Tf was first isolated from serum using anti-Tf immunomagnetic beads to ensure that only the Tf-bound iron was measured, improving the selectivity and accuracy of TSAT assessment. To demonstrate the practical utility of the device, it was validated by analyzing a certified reference material, showing excellent accuracy (E < 4%) and good precision (RSD ≤ 6%). Finally, 18 diagnosed serum samples from ischemic stroke patients were analyzed by this approach, and the results were compared with those obtained by urea-PAGE, showing not only an excellent correlation (r = 0.93, p < 0.05) but that the PAD approach has become statistically identical to the free-interference urea-PAGE. In comparison with the slow, tedious, and non-miniaturized-PAGE, this PAD approach exhibited attractive characteristics such as low cost, disposability, and connectivity, showing great potential for future point-of-care testing, especially in developing countries and/or remote areas, where access to medical or clinical facilities is limited
