On January 10, 2018, the Texas A&M University System Water-Energy-Food Initiative held the Water-Energy-Food Nexus Stakeholder Information Sharing and Engagement Workshop on the campus of Texas A&M University-San Antonio. The workshop involved over 70 stakeholders drawn from the water, energy, and food sectors in San Antonio and surrounding region. Stakeholders attending the workshop heard presentations on the status of San Antonio Case Study pilot projects and other WEF nexus work. Facilitated small-group sessions were held at the workshop to obtain stakeholder input on research questions to be asked, and on limitations and opportunities for stakeholder engagement on WEF nexus-related work in the San Antonio and the South Texas Region. Workshop participants also took before and after surveys to gauge knowledge about the WEF nexus. This report provides information on the outcomes of surveys, the workshop presentations and discussions, and the facilitated stakeholder sessions.https://digitalcommons.tamusa.edu/water_books/1002/thumbnail.jp

Forecasting Truck Parking Using Fourier Transformations

Truck-based transportation is the predominant mode used to transport goods and raw materials within the United States. While trucks play a major role in local commerce, a significant portion of truck activity is also long haul in nature. Long-haul truck drivers are continuously faced with the problem of not being able to secure a safe parking spot since many rest areas become fully occupied, and information about parking and availability is limited. Truck drivers faced with full parking lots/facilities either continue driving until a safe parking spot is located or park illegally. Both scenarios pose a hazard to the truck driver, as well as the surrounding road users. Disseminating forecasts of parking availability to truck drivers may help mitigate this hazard, since many truck drivers plan their parking in advance of arrival. Building on 1 year of nearly continuous truck parking data collection, this paper proposes and demonstrates a method for developing a dynamic forecasting model that can predict truck parking occupancy for any specified time within the present day, using only truck parking occupancy data from a trucking logistics facility in the northern San Joaquin Valley during 2016. Different versions of the dynamic model were studied and verified against successive weekdays with performance measured using the root-mean-square error (RMSE). Results indicated that for a particular day, the maximum error can range between 13 and 40 trucks, about 5% of the absolute maximum capacity of the facility

Radical Movement-Parties, Political Change and the Epistemology of Elections:Evidence from Lebanon

A growing literature seeks to bring agency into the study of movement-parties (M-Ps). Yet studies pay little attention to radical M-Ps which confront acute dilemmas when deciding to contest parliamentary elections in systems they deem illegitimate. This article problematizes radical M-Ps’ entry in elections and the meaning they attribute to the role and function of elections – their epistemology of elections. We examine three M-Ps – Beirut Madinati, LiHaqqi, and Muwatinun wa Muwatinat fi Dawla. We demonstrate that radical M-Ps with a coherent strategy for political change, one that includes an epistemology of elections, are more likely to mitigate and survive electoral dilemmas when entering elections. Radical M-Ps lacking such a strategy risk fragmentation and potential dissolution. Methodologically, we chose Lebanon because 1) during the period under study, it is a democracy and, consequently, a relevant case study for theories of party formation; and 2) it offers a controlled comparison of M-Ps in elections. Moreover, all three M-Ps emerged during a similar time-period, with similar social bases, and, at least originally, radical positions. Research is based on participation in, and observation of, protests and elections between 2011 and 2022, as well as primary and secondary source

Exploring the challenges and practices of citizenship education in national and civic education grades ten and eleven classroom in Lebanon

Throughout the twentieth and twenty-first centuries, Lebanon's pluralisms of multiconfessional\ud and multicultural communities continue to sway the nation to and fro\ud between conflict and post-conflict statuses. Since 1946, however, leaders in government\ud and education have focused on citizenship education as a fundamental vehicle for social\ud cohesion, justice and peace. Understandings of citizenship that teachers and students have\ud as well as their experiences of teaching and learning it inside the National and Civic\ud Education classroom provide insight into the challenges and practices of learning for\ud active citizenship.\ud Across 16 schools, data was collected from 19 civics teachers through semi-structured\ud interviews. Also, 435 students in years 10 and 11 participated in a self-reflective survey\ud pack and class discussion. The first section of the survey pack allowed students to\ud construct their conceptualizations of citizenship while the second section inquired into\ud their learning experiences.\ud The teachers presented a nationalist-based citizenship and an education that allowed\ud students to practice democracy and demanded strategies of memorization for learning\ud content knowledge. The students conceptualized a maximal notion of citizenship and\ud argued to replace current practices of memorization with collaborative and dialogic\ud learning activities. Students also found the textbooks prescriptive and, consequently,\ud hypocritical. Teachers and students experienced difficulties and limitations with the\ud curriculum, timetable and the management of emotions during controversial discussions.\ud Students and teachers in Lebanon have, for the first time to date, described their\ud conceptions of citizenship and discussed their civic education classroom experiences.\ud From the evidence, I discovered the limitations of dialogic and participative classroom\ud learning activities, a catch-22 of citizenship learning and a model of education for active\ud citizenship. The innovative methodology pioneered a participative learning activity and\ud an exercise demonstrating the capabilities of students contributing to education reform

COVID-19 Guidelines to Protect Healthcare Workers at Hospitals and Dental Professionals at Dental Office

BACKGROUND፡ Coronavirus disease 2019 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2. This study aimed to address the preventive procedures to protect healthcare workers at hospital to avoid COVID-19, and infection control procedures to protect dental professionals in dental office.METHODS: We conducted a search of published articles from PubMed, google scholar databases using key words such as COVID-19, healthcare worker, infection control, and dental practice. Relevant articles were identified and reviewed. Most published papers were clinical reports and case studies. We have selected some of the current published papers written in English in 2020.RESULTS: Infection control procedures to protect health workers at hospitals, and dental professionals at dental office were summurised and presented. Infection control procedures for healthcare workers at hospitals include Personal protective equipment, Korea filter (KF)94 respirator, goggles, face protector,disposable waterproof long-arm gown, and gloves, and others. Extra-protection procedures should be taken with old and vulnerable healthcare workers. Dental professionals should evaluate patients in advance before starting dental treatment. Aerosols generating procedures should be avoided and personal protective equipment should be used. Dental treatment should be restricted to emergency cases only.CONCLUSION: Old medical staff should be in safer distance to avoid infection, but young physicians and nurses should work at frontline as their immunity is better than their colleagues at old age. Screening patients and measurement of the body temperature are essential measures before dental treatment

Site-directed transposon integration in human cells

The Sleeping Beauty (SB) transposon is a promising gene transfer vector that integrates nonspecifically into host cell genomes. Herein, we attempt to direct transposon integration into predetermined DNA sites by coupling a site-specific DNA-binding domain (DBD) to the SB transposase. We engineered fusion proteins comprised of a hyperactive SB transposase (HSB5) joined via a variable-length linker to either end of the polydactyl zinc-finger protein E2C, which binds a unique sequence on human chromosome 17. Although DBD linkage to the C-terminus of SB abolished activity in a human cell transposition assay, the N-terminal addition of the E2C or Gal4 DBD did not. Molecular analyses indicated that these DBD-SB fusion proteins retained DNA-binding specificity for their respective substrate molecules and were capable of mediating bona fide transposition reactions. We also characterized transposon integrations in the presence of the E2C-SB fusion protein to determine its potential to target predefined DNA sites. Our results indicate that fusion protein-mediated tethering can effectively redirect transposon insertion site selection in human cells, but suggest that stable docking of integration complexes may also partially interfere with the cut-and-paste mechanism. These findings illustrate the feasibility of directed transposon integration and highlight potential means for future development

The effect of radiotherapy on survival of dental implants in head and neck cancer patients

Objectives: To explore the current literature of the survival of dental implants in irradiated head and neck cancer patients considering the role of implant location, bone augmentation, dose of radiation and timing of implant placement. Study Design: Pubmed search was conducted to identify articles published between January 2000 and December 2014 and presenting data of dental implant survival with radiotherapy in head and neck cancer patients. Studies on animal subjects and craniofacial implants were excluded. Results: 18 articles out of 27 were eligible for inclusion in this systematic review. 12 out of 18 studies reported favorable outcome of dental implants and radiotherapy with survival rates between 74.4% and 97%. Seven out of ten studies comparing the survival rates according to site of implant placement reported that implants were found to osseointegrate with greater success in the irradiated mandible than irradiated maxilla. 5 studies which compared implant survival in irradiated native bone versus irradiated grafted bone reported that irradiated grafted bone showed a significantly reduced dental implant survival rate in comparison to irradiated native bone. 6 out of 18studies in which radiation doses exceeded 70 Gy reported lower survival rates of dental implants in comparison to the studies in which radiation doses were ≤70Gy. Higher survival rates were reported in 2 studies in which implants placement was before radiotherapy in comparison to the remaining 16 studies in which implants placement was after radiotherapy. Conclusions: Dental implants may be affected by radiotherapy especially when they are placed in maxilla, in grafted bone, or after radiation, however, they remain a functional option for rehabilitation of head and cancer patients. More prospective cohort studies and randomized controlled trails are still needed to draw more evidence based conclusion

Outlook of carbon capture technology and challenges

The greenhouse gases emissions produced by industry and power plants are the cause of climate change. An effective approach for limiting the impact of such emissions is adopting modern Carbon Capture and Storage (CCS) technology that can capture more than 90% of carbon dioxide (CO2) generated from power plants. This paper presents an evaluation of state-of-the-art technologies used in the capturing CO2. The main capturing strategies including post-combustion, pre-combustion, and oxy – combustion are reviewed and compared. Various challenges associated with storing and transporting the CO2 from one location to the other are also presented. Furthermore, recent advancements of CCS technology are discussed to highlight the latest progress made by the research community in developing affordable carbon capture and storage systems. Finally, the future prospects and sustainability aspects of CCS technology as well as policies developed by different countries concerning such technology are presented
