Biography:
Augusto Foggiato, (DDS, MS, PhD) specialist in Radiology, Orthodontics and Orthopedics, has been working as an orthodontist in private practice for 29 years. He is Professor of Human Physiology, Radiology and Child Clinic I and II of the Dentistry Course, Jacarezinho Campus of the State University of North Parana is a delegate of the Regional Council of Dentistry/ CRO-Pr. He is a Researcher in Photodynamic Therapy and has 3 patents about PDT and has recently published work in reputed journal and has been serving as an editorial reviewer.
Abstract:
The Photodynamic Therapy is based on the association of a nontoxic photosensitizer and post-irradiation with a proper wavelength light source proper for the formation of reactive species oxygen. PDT may be an option for decontamination of surfaces of various materials that are based on the interaction between a non-toxic photosensitizer (PS) and irradiation with a wavelength light source suitable for the formation of reactive oxygen species with antimicrobial effects. These photoreactions have been used since the beginning of the 20th century as a tool to disable numerous pathogens and were established as a therapeutic platform commonly referred to as PDT. With help of powerful and well controlled light sources, such as lasers and light emitting diode (LED), great advances were made in photochemical and photobiotic studies the low-intensity light can also be associated with the administration of nontoxic PS to locally promote photochemical reactions that might induce cell death. In short, when the PS absorbs a photon, it is upgraded to an excitable state and can transfer charges or energy to molecular oxygen of the fundamental state inducing the formation of reactive species of oxygen. The byproducts of phenothiazine, such as toluidine blue and methylene blue (MB) are amongst the most studied PS for the antimicrobial photodynamic therapy (aPDT) and have been tested in the last decades in association with the red light to promote the bactericidal effect in vitro and in vivo. These results, based on studies in the literature, suggest good perspectives for the formulation of adequate clinical protocols for microbial control and thus, the aPDT open new frontiers and nontoxic and low-cost alternative for the disinfection of biomedical tools as non-critical instruments, besides being useful for the food industry. The objective of this paper is to demonstrate that devices such as PID (patent deposit MU-BR 20.2017.002297-3) and UPID (patent deposit MU-BR 20.2018.009356- 3) are capable of reducing contamination or microbial disinfection on solid surfaces of diverse materials in a sustainable and ecologically correct way.
Biography:
Jizheng Pan has more than 20 year’s experience in ecological restoration and constructed wetland. He is accomplished in the research on technology of ecological restoration in eutrophic lakes and treatment wastewater by constructed wetland with artificial aeration. He is skilful in ecological research of lakes. He is good at the pollution control and ecological restoration of lakes.
Abstract:
Lake Gehu is a severely eutrophic lake in southeast China. A series of restoration measures have been implemented since 2009 in northern Lake Gehu. This study compared aquatic plants, water quality, sediment, and phytoplankton between restoration and control areas to investigate the effect of restoration measures. The results demonstrated that aquatic macrophyte coverage increased from 0% to 10.6%; mean TP, TN, and CODMn concentrations increased by 50.0%, 42.4 %, and 40.8%, respectively, compared with those before the measures were carried out; the mean Secchi depth (SD) increased to 42.5cm, which is 1.4 times higher than that before restoration; the mean euphotic depth (Zeu) in the summer increased from 91 to 130cm; the mean chl.a concentration decreased from 34.8 to 20.2μg•L-1, compared with that before restoration; the Shannon–Wiener index of phytoplankton increased by 28.7%. The mean TP and TN concentrations in sediments decreased by 63.8% and 52.4%, respectively, compared with that before dredging. These results indicate that the restoration in northern Lake Gehu was effective. To complete the transformation from an algae-to a macrophyte-stable state within the region, further measures must be adopted. This restoration of a eutrophic lake can serve as a reference for similar eutrophic lakes.

Abstract:
Biologists are alerting us to the fact that we're experiencing major losses of biodiversity and wildlife habitat throughout the world and they're taking steps to address the issue. Corporations, on the other hand, are expanding operations and hoping to grow. It's just a matter of time before the actions of corporations and biologists collide. Corporations will soon face increasing stakeholder scrutiny and pressure to do their part to protect our planet's biodiversity and wildlife. Fortunately, conservation versus profit is not a zero sum game where the winner takes all. There are many win-win scenarios, which are good for business (e.g., reduced costs, reduced risk, and increased profits) and good for biodiversity (e.g., healthy species, populations, and ecosystems). This presentation will highlight the role of business in conserving biodiversity, emphasizing actions that companies can take that are profitable from the perspectives of business, wildlife, and biodiversity. In my presentation, I provide strategies that businesses can implement to address four major biodiversity threats: habitat destruction; invasive species; pollution; and overharvesting, along with the value proposition for each strategy and real-world examples.

Title: Capabilities of planted groundcovers in promoting sustainability of revegetated soil slopes
Biography:
Dr. Lung CHAU has completed his postgraduate study in The Chinese University of Hong Kong and his research focuses on the investigation of adaptable native groundcovers for ecological greening of man-made slopes. He is also interested in exploring appropriate plant traits and characteristics in enhancing the ecological and environmental values of urban landscapes. Dr. Lung CHAU has also involved in extensive urban greening research projects of Hong Kong and previously worked in an environmental non-government organization to give environmental and conservation education to students and the public.
Abstract:
Urban expansion leads to a large scale of terrestrial habitat loss in Hong Kong. Instead, numerous soil slopes have been established to facilitate infrastructure development owing to its hilly topography. The sophisticated slope upgrading techniques currently available make revegetation of these urban landscapes possible, thus enhancing ecological restoration. Among the plants selected for revegetation, native plants are recently preferred owing to their adaptability to local climates and beneficial ecological roles. Native trees and shrubs are widely studied for their significance to the urban environment whereas groundcovers are usually ignored. The abilities of groundcovers to provide sustainable plant covers and positively influence ecology are occasionally recognized and need to be assessed. Areas with differing degrees of development that have dramatically different environmental conditions may result in alteration of this plant community. In our study, an analysis of groundcover vegetation on extensive soil slopes will be carried out in suburban and urban areas of Hong Kong to assess plant abundance and analyze the substrates for their nutrient status. We will also evaluate slope performance to determine any correlation with the groundcover community. All these provide useful information in reviewing the current planting strategy in promoting a biodiverse city. Constructive suggestions based on our precise findings will be made to improve the revegetation work and any practical measures will be recommended to other cities to promote the sustainable development.

Title: Differences in chemical properties and aquatic macroinvertebrate populations between forested and agricultural sites
Biography:
Sarah Bond is completing her degree in Biology at St. Olaf College and will go on to pursue a degree in Environmental Health.
Abstract:
Using biota as important indicators of environmental quality improves upon standard chemical monitoring systems. Invertebrate communities are often used for aquatic bioassessment investigations. Rice Creek in Northfield, MN, is a cold trout stream surrounded by agricultural land and patches of forestry. Agricultural activities are primary contributors to the degradation of streams and lakes in the United States. This study tests the differences in water quality and macroinvertebrate populations between agricultural and forested areas and answers whether macroinvertebrate populations are adequate indicators of water quality. The goal of this study is to understand the relationship between water qualities and macroinvertebrate populations as well as provide evidence for conserving forested areas around stream communities. As one of the few streams in the state with native brook trout, it is important to understand the stream’s general health as well as the effect of human actions at the landscape scale. Four study sites were sampled three times for chemical properties. Macroinvertebrates were collected and identified. The data reveals no significant differences between agricultural and forested sites over each sampling period but that the water quality of Rice Creek is not ideal for trout and many other organisms. It provides evidence for increased compliance with Minnesota buffer laws and to decrease disturbance of the stream to preserve healthy aquatic communities.
