Mesiodistal sizes and intermaxillary tooth-size ratios of two populations; Spanish and Peruvian. A comparative study

Introduction: Adequate tooth-size ratios are required to ensure the satisfactory outcome of orthodontic treatment. Consequently, various methods of measuring tooth-size ratios have been developed being the Bolton ratio the most commonly accepted, known and used one. This ratio depending directly on mesiodistal tooth size has been associated with different ethnic backgrounds. Some authors suggest the need for specific standards for every population. Objectives: The objectives of our study were; to measure and to compare mesiodistal tooth sizes and the Anterior and Overall Bolton ratios in two different populations, one Peruvian and the other Spanish with the same digital method. Material and Methods: The sample included 149 individuals composed of two groups; 99 Spanish (mean age 14.19), 65 being females and 34 males and 50 Peruvian (mean age 14.46), 18 being males and 32 females. The mesiodistal sizes of each of the patients were measured using a digital method and the Anterior and Overall Bolton ratios were calculated. Results: Tooth size does indeed involve a strong ethnic component, and the Anterior Bolton ratio is specific for each ethnic group. Conclusions: The conclusions are; tooth sizes of the Peruvian population were greater than those of the Spanish population. The Anterior Bolton ratio of Peruvian individuals was greater than that of the Spanish, whereas no differences were found for Overall Bolton ratio. These differences suggest the need for specific standards for the Spanish and Peruvian population. © Medicina Oral S. L

Climatic vulnerabilities and ecological preferences of soil invertebrates across biomes.

Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross-biome survey including 83 locations across six continents to advance our understanding of the ecological preferences and vulnerabilities of the diversity of dominant and functionally important soil invertebrate taxa, including nematodes, arachnids and rotifers. The diversity of invertebrates was analyzed through amplicon sequencing. Vegetation and climate drove the diversity and dominant taxa of soil invertebrates. Our results suggest that declines in forest cover and plant diversity, and reductions in plant production associated with increases in aridity, can result in reductions of the diversity of soil invertebrates in a drier and more managed world. We further developed global atlases of the diversity of these important soil invertebrates, which were cross-validated using an independent database. Our study advances the current knowledge of the ecological preferences and vulnerabilities of the diversity and presence of functionally important soil invertebrates in soils from across the globe. This information is fundamental for improving and prioritizing conservation efforts of soil genetic resources and management policies

History of discovery of the patagonian lizards

Knowledge of the history is necessary to understand why things are today as they are. Argentinean and Chilean Patagonia have a very interesting story about the native fauna and its discovery. The main character of this story is an adventurer spirit wanting to increase knowledge by traveling to the “end of the world”, ignoring barriers only to search and see what is beyond. Many well-known naturalists have visited this land eager and willing to find new species never seen before, while others have made some amazing contributions while never setting one foot on Patagonian soil. In this chapter, we intend to summarize how Patagonian herpetofauna was discovered, described and studied over time. In addition, we want to mention important scientists, whose work led the way for the future researchers to come.Fil: Williams, Jorge Daniel.

Building a Culture of Critical and Creative Thinking. Creating and Sustaining Higher-Order Thinking as part of a Quality Enhancement Plan

[EN] Creating and Sustaining Higher-Order Thinking as part of a Quality Enhancement Plan at a US UniversityThe TH!NK initiative at North Carolina State University seeks to bridge the gap between evidence-based research on teaching and actual teaching practices in the classroom. Through this work, the culture of teaching and learning on our campus is being transformed from teacher-centered to student-centered instruction that promotes higher-order thinking across a diverse array of disciplines. Participating faculty engage in intensive faculty development; create discipline-specific classroom activities and assignments; become adept at providing students feedback on their thinking skills; and engage in a learning community to share and provide peer feedback on pedagogical innovations. The primary student learning outcome (SLO) is for students to apply critical and creative thinking skills and behaviors in the process of solving problems and addressing questions. Methods to achieve the institutional transformation include implementation of a comprehensive faculty development focused on the use of evidence-based pedagogy that promotes higher-order thinking, and rigorous outcomes assessment to provide means for continual improvement. The program has expanded into multiple phases, and involves strategies to create a more sustainable culture of critical and creative thinking through formal and informal learning and scholarship.Allen, T.; Queen, S.; Gallardo-Williams, M.; Parks, L.; Auten, A.; Carson, S.

Global ecological predictors of the soil priming effect.

Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, biotic communities, and soil conditions, and evaluated the apparent soil priming effect using 13C-glucose labeling. Here we show that the magnitude of the positive apparent priming effect (increase in CO2 release through accelerated microbial biomass turnover) was negatively associated with SOC content and microbial respiration rates. Our statistical modeling suggests that apparent priming effects tend to be negative in more mesic sites associated with higher SOC contents. In contrast, a single-input of labile C causes positive apparent priming effects in more arid locations with low SOC contents. Our results provide solid evidence that SOC content plays a critical role in regulating apparent priming effects, with important implications for the improvement of C cycling models under global change scenarios

A Power-Line Communication System Governed by Loop Resonance for Photovoltaic Plant Monitoring

Within this paper, a PLC system that takes advantage of the loop resonance of an entire DC-PV string configured as a circular signal path is developed and implemented. Low cost and extremely simple transceivers intended to be installed within each PV module of a string have been designed and successfully tested. In addition, an anti-saturation coil has been conceived to avoid saturation of the core when the entire DC current of the string flows through it. Bi-directional half-duplex communication was successfully executed with up to a 1 MHz carrier frequency (150 kbps bitrate), using a simple ASK modulation scheme. The transmission and reception performance are presented, along with the overall system cost in comparison to the previous literatureThis research was funded by the Universidad dee Valladolid with the predoctoral contracts of 2020 cofunded by Santander Bank.
