Wild NYC: Building Biodiversity in Fresh Kills and City Parks

This dissertation is an anthropological field study of the work of urban ecological maintenance being conducted in New York City through the analysis of the reclamation and biotic restoration of the Fresh Kills landfill, located in the borough of Staten Island. This landfill was once the largest urban dump in the United States. Its 2,200 acres of trash buried in four mounds have polluted an area historically noted for its natural beauty as a collection of marshes and woodlands bordering the Kill Van Kull, a tidal strait that flows into the New York Harbor. The current plan for park and nature reserve introduces rolling grassland habitats otherwise extirpated in the region and re-introduces native plants to enhance the area\u27s biotic diversity. The site\u27s large acreage will also link up with and expand the Staten Island Greenbelt. Fresh Kills, once transformed, will become one of the largest urban nature preserves in the city. This dissertation also explores the essential maintenance work performed by researchers, city workers, and volunteers alike for creating and preserving wild spaces in New York City. Despite the ecological benefits envisioned in the Fresh Kills conversion, there are challenges ahead for implementing sustainability. Chief among them is the scarce funding for land reclamation in light of competing urban priorities. The substantial commitment to convert the world\u27s largest landfill into an urban park and nature preserve, however, holds important lessons for public and non-profit agencies interested in urban environmental improvement

Oregano essential oil-pectin edible films as anti-quorum sensing and food antimicrobial agents

Edible films can be used as carriers for antimicrobial compounds to assure food safety andquality; in addition, pathogenesis of food bacteria is related to a cell to cell communicationmechanism calledquorum sensing(QS). Oregano essential oil (OEO) has proved to beuseful as food antimicrobial; however, its foodapplications can be compromised by thevolatile character of its active constituents.Therefore, formulation of edible films containingOEO can be an alternative to improve its food usages. QS inhibitory activity of OEO andpectin-OEO films was evaluated usingChromobacterium violaceumas bacterial model.Additionally, antibacterial activity was tested againstEscherichia coliO157:H7,SalmonellaCholeraesuis,Staphylococcus aureus,andListeria monocytogenes. OEO was effective toinhibit bacterial growth at MIC of 0.24 mg/mL for all tested bacteria and MBC of 0.24,0.24, 0.48, and 0.24 mg/mL againstE. coliO157:H7,S.Choleraesuis,S. aureus, andL.monocytogenes, respectively. Pectin-films incorporated with 36.1 and 25.9 mg/mL of OEOshowed inhibition diameters of 16.3 and 15.2 mm forE. coliO157:H7; 18.1 and 24.2 mm forS.Choleraesuis; 20.8 and 20.3 mm forS. aureus; 21.3 and 19.3 mm forL. monocytogenes,respectively. Pectin-OEO film (15.7 mg/mL) was effective againstE. coliO157:H7 (9.3 mm),S. aureus(9.7 mm), andL. monocytogenes(9.2 mm), but not forS.Choleraesuis. Allconcentrations of OEO (0.0156, 0.0312, 0.0625 and 0.125 mg/mL) and pectin-OEO films(15.7, 25.9 and 36.1 mg/mL) showed a significant anti-QS activity expressed as inhibition ofviolacein production byC. violaceum. Additionally, the application of pectin-OEO films waseffective reducing total coliforms, yeast, and molds of shrimp and cucumber slices storedat 4◦C during 15 d.These results demonstrated the potential of pectin films enriched withOEO as food related microorganisms and QS inhibitorsFil: Alvarez, María Victoria.

A 3-D indoor analysis of path loss modeling using kriging techniques

This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median path loss modeling and then includes ordinary Kriging to interpolate shadowing. The performance of this method is evaluated by investigating the spatial structure that follows shadowing through the semivariogram, covariance function, and correlogram as variography tools. It is shown that semivariogram outperforms the other statistics to describe shadowing spatial continuity in path loss modeling in terms of the mean absolute error.This work was supported by the National Council of Science and Technology CONACYT, through the student scholarship number 746015, under Project RTI2018-095499-B-C31, funded by the Ministerio de Ciencia, Innovación y Universidades, Gobierno de España (MCIU/AEI/FEDER, UE)

Riesgos psicosociales en personal de un hospital privado de la ciudad de Guayaquil en el año 2021

Psychosocial risks are those situations that workers endure within their workplace and that can cause both physical and psychological effects. The objective of this work was to analyze the psychosocial risks in personnel of a private hospital in the city of Guayaquil in the year 2021. A quantitative methodology was used, a descriptive, cross-sectional study, the study population consisted of 347 people. The Psychosocial Risk Assessment questionnaire was used. The data obtained from the questionnaire were entered into the data tabulation tool of the psychosocial risk assessment questionnaire that is available on the institutional website of the Ministry of Labor. The results show that for dimension 1 Work load and pace, with 73% low risk and 27% medium-high risk, for dimension 8.2 Workplace harassment, 58% were exposed to medium risk and 42% were exposed to medium-high risk. high risk. The overall result according to the data from the survey applied in the private hospital showed 84% low risk, and 16% are between medium and high risk. Regarding the conclusions, it is corroborated that hospital employees are exposed to a low risk of psychosocial factors.Los riesgos psicosociales son aquellas situaciones que sobrellevan los trabajadores dentro de su ámbito laboral y que pueden causar afectaciones tanto física como psicológicas.

On the dynamics of the Zanzibar Channel

The definitive version was published in Journal of Geophysical Research: Oceans 120 (2015): 6091–6113, doi:10.1002/2015JC010879.The Zanzibar Channel lies between the mainland of Tanzania and Zanzibar Island in the tropical western Indian Ocean, is about 100 km long, 40 km wide, and 40 m deep, and is essential to local socioeconomic activities. This paper presents a model of the seasonal and tidal dynamics of the Zanzibar Channel based on the Regional Ocean Modeling System (ROMS) and a comparison of the model and observations. The seasonal dynamics of the channel is forced by remote processes and the local wind. Remote forcing creates the East African Coastal Current, a portion of which flows through the channel northward with a seasonally varying magnitude. The local wind enhances this seasonality in the surface Ekman layer, resulting in a stronger northward flow during the southwest monsoon season and a weak northward or occasionally southward flow during the northeast monsoon season. The tidal flows converge and diverge in the center of the channel and reduce the transport in the channel. The remotely forced, wind-forced, and tidal dynamics contain 5%, 3%, and 92% of the total kinetic energy, respectively. Despite their low kinetic energy, the remotely forced and wind-forced flows are most relevant in advecting channel water to the open ocean, which occurs in 19 days at the peak of the southwest monsoon season. The channel is well mixed, except during brief periods in the two rainy seasons, and temporarily cools between December and February. The dispersion of passive tracers is presented as an example of potential model applications.National Science Foundation Grant Numbers: OISE-0827059 , OCE-0550658 , OCE-0851493 , OCE-09274722016-03-1
