Augmented Active-Bending Formwork for Concrete, A Manufacturing Technique for Accessible Local Construction of Structural Systems

This research introduces Augmented Reality (AR) for manufacturing concrete structures through an open platform for autonomous construction. The study was developed under the following scopes: computational algorithms for bending simulations, materiality tests, system implementation, and a set of Augmented Reality (AR) tools. AR devices offer a technological tool that allows for a self-built environment through holographic guidance, allowing the untrained workforce to participate in the process. This technology can help users select the system to construct through an Open-Source platform, reducing the gap between complex computational geometries and construction processes. The research aims to investigate a building system that could benefit the UN Objectives SDG 10 by increasing the access to technology in undeveloped communities, SDG 11 and SDG 12 by promoting a self-sustainable method of construction based on local resources and material efficiency. In conjunction with the development of the AR Platform and augmented manufacturing, a 1:1 prototype was built in Quito, Ecuador, with the help of seven people with no previous knowledge of digital tools or construction. Presenting a novel, fast, and affordable concrete formwork connected with AR assisted assembly methods that facilitate access to more efficient and advanced building technology

Fabrication of Complex Clay Structures Through an Augmented Reality Assisted Platform

The relationship between clay manufacturing and architectural design has a long trajectory that has been explored since the early 2000s. From a 3D printing or assembly perspective, using clay in combination with automated processes in architecture to achieve computational design solutions is well established. (Yuan, Leach & Menges, 2018). Craft-based clay art, however, still lacks effective computational design integration. With the improvement of Augmented Reality (AR) technologies (Driscoll et al., 2017) and the appearance of digital platforms, new opportunities to integrate clay manufacturing and computational design have emerged. The concept of digitally transferring crafting skills, using holographic guidance and machine learning, could make clay crafting accessible to more workers while creating the potential to share and exchange digital designs via an open-source manufacturing platform. In this context, this research project explores the potential of integrating computational design and clay crafting using AR. Moreover, it introduces a platform that enables AR guidance and the digital transfer of fabrication skills, allowing even amateur users with no prior making experience to produce complex clay components

Political change as group-based control : threat to personal control reduces the support for traditional political parties

People desire agentic representations of their personal and collective selves, such as their own nation. When national agency is put into question, this should increase their inclination to restore it, particularly when they simultaneously lack perceptions of personal control. In this article, we test this hypothesis of group-based control in the context of political elections occurring during socio-economic crises. We propose that people who are reminded of low (vs. high) personal control will have an increased tendency to reject traditional political par- ties that stand for the maintenance of a non-agentic political system. We experimentally manipulated the salience of low vs. high personal control in five studies and measured par- ticipants’ intentions to support traditional and new political parties. Across four of five stud- ies, in line with the predictions, low personal control reduced support for the main traditional conservative party (e.g., Partido Popular (PP) in Spain, the Republicans in France). These results appeared in contexts of national economic and/or political crisis, and were most pro- nounced when low (vs. high) national agency was made salient in Studies 4 and 5. The find- ings support the notion that rejecting the stability of the national political system can serve as a means to maintain a sense of control through the collective self

Efecto del 1-MCP en la vida poscosecha de Lilium spp. fertilizado foliarmente con calcio y boro

Bajo condiciones de invernadero, en Toluca, México, 2009, en la presente investigación se estudió el efecto de la fertilización foliar con calcio (Ca) y boro (B) en el crecimiento y vida de anaquel de Lilium 'Nueva Escocia'. Se fertilizó foliarmente con 43 mg L-1 CaO y 15 mg L-1 B o 130 mg L-1 CaO y 30 mg L-1B, además, se tuvo un control sin fertilización foliar. Después de la cosecha se aplicó 0 o 500 nl L-1 de 1-metilciclopropeno (1-MCP), un antagonista del etileno, por 8 h en un contenedor de plástico herméticamente cerrado, y se evaluó la vida postcosecha. A la cosecha, generalmente, el contenido de Ca y B así como de azúcares totales en los tejidos vegetales fue mayor en las plantas con 130 mg L-1 CaO y 30 mg L-1 B o con 43 mg L-1 CaO y 15 mg L-1 B que en el control. El 1-MCP aumentó (p< 0.05) 2.5 días la vida en florero de los tallos no fertilizados foliarmente; en los tallos tratados con 43 mg L-1CaO y 15 mg L-1 B aquellos con 1-MCP duraron hasta 4.5 días más en comparación de tallos no tratados. Mientras que en tallos tratados con 130 mg L-1 CaO y 30 mg L-1 B no hubo diferencias de vida en florero por efecto del 1-MCP

Alzheimer’s Disease Studies in the Tex-Mex Border: Dissecting a Complex Multifactorial Problem

Purpose: Alzheimer’s Disease (ALZ) is the leading cause of dementia in the aging population, and Latinos have \u3e3 times higher risk to develop dementia than the overall US population. Although several studies have examined for possible causes of this increased risk, lack of comprehensive information plus a reduced number of Latino samples available in each study have hindered the answers. Description: The University of Texas Rio Grande Valley has joined two large studies looking for multiple biomarkers associated with ALZ: The South Texas Alzheimer’s Center Clinical Data Repository and Biobank (STAC) and the Texas Alzheimer’s Research and Care Consortium (TARCC). We are now collecting clinical data along with neuroimaging and lab biomarkers from each individual enrolled in these studies, with the aim to enroll a large majority of Latinos in our site sample, which will help to elucidate the differences and risk factors inherent to our population in the border. We are also analyzing data from different Latin-American studies to study specific genetic risks, environmental factors, and their interactions. Partners: UTRGV has partnered with UTHSCSA for the STAC study and with many other academic research institutions at TARCC. We aim to provide experiences of clinical training to our psychology students and residents of medical specialties, as well as analysis opportunities and opening postdoctoral positions related to the development of this field at UTRGV. Looking Ahead: We expect to generate substantial contributions to the knowledge of cognitive decline in underserved populations, which can lead to improved treatments and better clinical care. Postdoctoral positions will be opening soon at the Institute of Neuroscience

Cyclooxygenase-2 polymorphisms confer susceptibility to sarcoidosis but are not related to prognosis

SummaryBackgroundThe aim of this multicenter study was to investigate the relationship between single nucleotide polymorphisms (SNPs) of the cyclooxygenase-2 (COX2) gene and susceptibility to sarcoidosis, as well as the relation between these SNPs and the evolution of the disease.Material and methodsThis multicenter investigation involved seven hospitals in Spain. We used a case–control design followed by a prospective follow-up study. Sarcoid patients were recruited from the participating institutions during outpatient routine visits. Age- and gender-matched control subjects were recruited mainly from among outpatients attending the participating hospitals. Four SNPs in the COX2 gene (COX2.5909 T > G, COX2.8473 T > C, COX2.926 G > C, and COX2.3050 G > C) were genotyped using fluorescent hybridization probes among 131 patients with sarcoidosis (63 males; mean age: 47 ± 15 years) and 157 healthy controls (83 males; mean age: 50 ± 16 years). We employed a binomial multiple logistic regression analysis to test the association between the selected SNPs and disease susceptibility. The clinical, functional and radiological prognosis of the sarcoidosis patients was determined after a mean follow-up of 37.4 ± 30.4 months.ResultsCarriers of the homozygous CC genotype of the COX2.8473 T > C polymorphism had a higher risk of sarcoidosis compared with TT carriers (OR: 3.08; 95% CI: 1.2–7.7; p = 0.035). 84% of patients achieved improvement or complete remission at follow-up. No association between the investigated SNPs and prognosis was seen.ConclusionsOur data suggest that the homozygous CC genotype of the COX2.8473 T > C polymorphism may be associated with sarcoidosis susceptibility. No significant association with prognosis was detected
