Host-Specific Activation of Entomopathogenic Nematode Infective Juveniles.

Entomopathogenic nematodes (EPNs) are potent insect parasites and have been used for pest control in agriculture. Despite the complexity of the EPN infection process, hosts are typically killed within 5 days of initial infection. When free-living infective juveniles (IJs) infect a host, they release their bacterial symbiont, secrete toxic products, and undergo notable morphological changes. Collectively, this process is referred to as "activation" and represents the point in a nematode's life cycle when it becomes actively parasitic. The effect of different host tissues and IJ age on activation, and how activation itself is related to virulence, are not well understood. Here, we employed a recently developed bioassay, which quantifies IJ activation, as a tool to address these matters. Appreciating that activation is a key part of the EPN infection process, we hypothesized that activation would positively correlate to virulence. Using the EPNs Steinernema carpocapsae and S. feltiae we found that EPN activation is host-specific and influenced by infective juvenile age. Additionally, our data suggest that activation has a context-dependent influence on virulence and could be predictive of virulence in some cases such as when IJ activation is especially low

The Energy Worker Profiler from Technologies to Skills to Realize Energy Efficiency in Manufacturing

In recent years, the manufacturing sector has been responsible for nearly 55 percent of total energy consumption, inducing a major impact on the global ecosystem. Although stricter regulations, restrictions on heavy manufacturing and technological advances are increasing its sustainability, zero-emission and fuel-efficient manufacturing is still considered a utopian target. In parallel,companies that have invested in digital innovation now need to align their internal competencies to maximize their return on investment. Moreover, a primary feature of Industry 4.0 is the digitization of production processes, which offers the opportunity to optimize energy consumption. However, given the speed with which innovation manifests itself, tools capable of measuring the impact that technology is having on digital and green professions and skills are still being designed. In light of the above, in this article we present the Worker Profiler, a software designed to map the skills currently possessed by workers, identifying misalignment with those they should ideally possess to meet the renewed demands that digital innovation and environmental preservation impose. The creation of the Worker Profiler consists of two steps: first, the authors inferred the key technologies and skills for the area of interest, isolating those with markedly increasing patent trends and identifying green and digital enabling skills and occupations. Thus, the software was designed and implemented at the user-interface level. The output of the self-assessment is the definition of the missing digital and green skills and the job roles closest to the starting one in terms of current skills; both the results enable the definition of a customized retraining strategy. The tool has shown evidence of being user-friendly, effective in identifying skills gaps and easily adaptable to other contexts

The crustacean fauna of Bayan Onjuul area (Tôv Province, Mongolia) (Crustacea: Branchiopoda, Copepoda, Ostracoda)

Due to the wide extension of the country and to the shortness of the ice-free season, the inlandwater crustacean fauna of Mongolia is, to date, incompletely known. However, based on the available literature, Mongolian inland waters appear to be characterised by a high biodiversity, including some taxa still waiting to be described. Novel data on the branchiopod, copepod, and ostracod crustaceans from central Mongolian steppe, from the “Tuul” and “Umard goviin guveet-Khalhiin” hydrographical basins, are presented herein. While large branchiopods, some anomopod families, and copepods are well-represented in the collected samples, ostracods are rare, and the anomopod family Chydoridae is apparently absent in the sampled water bodies. The anomopod Macrothrix dadayi and the cyclopoid Microcyclops afghanicus are here reported for the first time for the Mongolian fauna. Furthermore, two branchiopods (i.e. Moina sp. and Artemia sp.), three copepods (i.e. Diacyclops sp., Arctodiaptomus cf. alpinus, and Arctodiaptomus cf. wierzejskii), and one ostracod taxon (i.e. Heterocypris sp.), were not identified to species level and therefore deserve further study. The main ecological determinants of species distribution in the study area were examined using canonical multivariate analysis, which explained around 40% of total variation of the species similarity matrix; the main environmental drivers of crustacean assemblages in the study area were elevation, water turbidity, water temperature and electrical conductivity. The ecological preferences of crustacean species in the area are briefly discussed

Teaching and the art archivist: on strategies for rereading with a gender perspective

Como ya planteaba Griselda Pollock, actualmente nuestras prácticas y pensamientos generan disonancias críticas frente a la historia del arte tradicional, y es allí donde se nos habilita a «imaginar otras formas de ver y leer prácticas visuales distintas de aquellas encerradas en la formación canónica» (2007, p.141). Nos proponemos, entonces, (re)pensar estrategias y marcos teóricos, que nos posibiliten enseñar contenidos desde otras perspectivas. Intentaremos rescatar archivos de experiencias artísticas atravesadas por los géneros, que promuevan una actitud crítica, expandiendo los límites de la visualidad y generando interrogantes que permitan construir nuevos saberes por fuera de los cánones establecidos.As Griselda Pollock has already stated, our practices and thoughts currently generate critical dissonances in the face of traditional art history, and it is there where we are enabled to «(...) imagine other ways of seeing and reading visual practices different from those enclosed in canonical training» (2007, p.141). We propose, then, to (re)think strategies and theoretical frameworks that enable us to teach content from other perspectives. We will try to rescue archives of artistic experiences crossed by genders that promote a critical attitude, expanding the limits of visuality and generating questions that allow us to construct new knowledge outside the established canons.Facultad de Arte

Ámbar. Diseño de calzado casual femenino a partir de materias primas recuperadas

Actualmente la industria colombiana, específicamente el sector de marroquinería y calzado, se está enfrentando a múltiples problemas que desde ya y con una proyección a futuro afectarán el desarrollo económico, ambiental y social del país. En esta industria no solo se dan daños a nivel ecológico, evidenciados en los altos índices de contaminación de cuerpos acuíferos, destrucción de bosques y la incineración de desechos, sino también en términos de bienestar humano, pues estas prácticas dañinas se convirtieron en una amenaza para la salud de los trabajadores del sector (OCU,2016). Es por esto, que se encontró una oportunidad de abarcar esta problemática en el proyecto, de tal manera que se generen alternativas y soluciones con impacto positivo a nivel social, económico y ambiental en Colombia, aportando al progreso sostenible del país, tomando como pilar la ergoecología. Así se llegó a una propuesta de diseño que incluye una línea de calzado casual femenino, inspirada en formas de la naturaleza y hecha con materiales recuperados y transformados naturalmente. Su diseño responde a características del mercado, a estándares ergonómicos y ecológicos, y evidentemente a un alto grado de innovación, en relación a los materiales implementados. Adicional a esto, se busca con este trabajo establecer las bases para dar continuidad a futuro en un proyecto de emprendimiento que conforme una comunidad de trabajo sostenible, genere beneficios no solo a la empresa, sino también a esos clientes internos que hacen posible la materialización de las ideas.Currently the Colombian industry, specifically the leather goods and footwear sector, is facing multiple problems that, from now on and with a future projection, will affect the economic, environmental and social development of the country. In this industry, not only damage occurs at the ecological level, evidenced by the high rates of contamination of aquifers, destruction of forests and the incineration of waste, but also in terms of human well-being, as these harmful practices became a threat to the health of workers in the sector (OCU, 2016). It is for this reason that an opportunity was found to cover this problem in the project, in such a way that alternatives and solutions with positive social, economic and environmental impact are generated in Colombia, contributing to the sustainable progress of the country, taking as a pillar the ergoecology. This led to a design proposal that includes a line of casual women's shoes, inspired by nature forms and made with materials recovered and transformed naturally. Its design responds to market characteristics, to ergonomic and ecological standards, and obviously to a high degree of innovation, in relation to the materials implemented. In addition to this, it is sought with this work to establish the bases to give continuity to future in a project of entrepreneurship that according to a community of sustainable work, generates benefits not only to the company, but also to those internal clients that make possible the materialization of the ideas.Diseñador (a) IndustrialPregrad

Birefringent Fourier filtering for single molecule Coordinate and Height super-resolution Imaging with Dithering and Orientation

Super-resolution imaging based on single molecule localization allows accessing nanometric-scale information in biological samples with high precision. However, complete measurements including molecule orientation are still challenging. Orientation is intrinsically coupled to position in microscopy imaging, and molecular wobbling during the image integration time can bias orientation measurements. Providing 3D molecular orientation and orientational fluctuations can offer new ways to assess the degree of alignment of protein structures, which cannot be monitored by pure localization. Here we demonstrate that by adding polarization control to phase control in the Fourier plane of the imaging path, all parameters can be determined unambiguously from single molecules: 3D spatial position, 3D orientation and wobbling or dithering angle. The method, applied to fluorescent labels attached to single actin filaments, provides precisions within tens of nanometers in position and few degrees in direction
