A joint approach for strategic bidding of a microgrid in energy and spinning reserve markets

n the electricity market, short-term operation is organized in day-ahead and real-time stages. The two stages that are performed in different time intervals have reciprocal effects on each other. The paper shows the strategy of a microgrid that participates to both day-ahead energy and spinning reserve market. It is supposed that microgrid is managed by a prosumer, a decision maker who manages distributed energy sources, storage units, Information and Communication Technologies (ICT) elements, and loads involved in the grid. The strategy is formulated considering that all decisions about the amount of power to sell in both markets and the price links to the offer, must be taken contextually and at the same time, that is through a joint approach. In order to develop an optimal bidding strategy for energy markets, prosumer implements a nonlinear mixed integer optimization model: in this way, by aggregating and coordinating various distributed energy sources, including renewable energy sources, micro-turbines–electricity power plants, combined heat and power plants, heat production plants (boilers), and energy storage systems, prosumer is able to optimally allocate the capacities for energy and spinning reserve market and maximize its revenues from different markets. Moreover, it is considered that both generators and loads can take part in the reserve market. The demand participation happens through both shiftable and curtailable loads. Case studies based on microgrid with various distributed energy sources demonstrate the market behavior of the prosumer using the proposed bidding model

Successful Sports Philanthropy Communication Strategies: A Focus on Major League Soccer’s (MLS) Promotion of the Safe Places to Play Initiative

Organizations have recognized the value and importance of corporate social responsibility by dedicating their time and resources to help the surrounding community. However, primary research centers on the traditional business world and not on how corporate social responsibility has evolved in other highly influential institutions, such as professional sporting organizations. Previous research has also explored nonprofit communication, yet few have followed how various organizations communicate a specific and shared campaign. Therefore, this thesis explores what communication strategies different community relations departments and foundations of Major League Soccer teams utilize regarding the Safe Places to Play initiative. Semi-structured interviews were conducted with representatives of these organizations, and themes were derived from their responses. The results of this study will benefit academics and professionals by advancing scholarship and providing insight for professional growth

Multimodal Treatment Eliminates Cancer Stem Cells and Leads to Long-Term Survival in Primary Human Pancreatic Cancer Tissue Xenografts.

We and others have previously identified a subpopulation of pancreatic cancer stem cells within the tumor as a critical therapeutic target and additionally shown that the tumor stroma represents not only a restrictive barrier for successful drug delivery, but also serves as a paracrine niche for cancer stem cells. Therefore, we embarked on a large-scale investigation on the effects of combining chemotherapy, hedgehog pathway inhibition, and mTOR inhibition in a preclinical mouse model of pancreatic cancer. EXPERIMENTAL DESIGN: Prospective and randomized testing in a set of almost 200 subcutaneous and orthotopic implanted whole-tissue primary human tumor xenografts. RESULTS: The combined targeting of highly chemoresistant cancer stem cells as well as their more differentiated progenies, together with abrogation of the tumor microenvironment by targeting the stroma and enhancing tissue penetration of the chemotherapeutic agent translated into significantly prolonged survival in preclinical models of human pancreatic cancer. Most pronounced therapeutic effects were observed in gemcitabine-resistant patient-derived tumors. Intriguingly, the proposed triple therapy approach could be further enhanced by using a PEGylated formulation of gemcitabine, which significantly increased its bioavailability and tissue penetration, resulting in a further improved overall outcome. CONCLUSIONS: This multimodal therapeutic strategy should be further explored in the clinical setting as its success may eventually improve the poor prognosis of patients with pancreatic ductal adenocarcinoma

Kelly Ferruzzi Interview, April 22, 2021

In this interview, Kelly Ferruzzi discusses working for George’s Distributing selling alcohol to restaurants and retail stores in Missoula, Montana, and how they made it through the COVID-19 pandemic. Ferruzzi works mainly with restaurants, supplying them with wine and helping them decide on wine purchases by having wine tastings and assisting them in creating menus. She discusses how, during the pandemic, George’s could sell the more expensive bottles of wine that were only available in restaurants to retail stores since many restaurants were closed. Ferruzzi says that George’s was good to their employees during the pandemic, ensuring they got 80 percent of the pay they had been getting the previous year. Once George’s got a Paycheck Protection Program (PPP) loan that allowed them to pay their employees 100 percent. Also, staff meetings during the pandemic were held weekly on Zoom, and they also did Zoom alcohol tastings.https://scholarworks.umt.edu/wetmissoulacovid19_oralhistory/1013/thumbnail.jp

Thermally induced intramolecular hydrogen atom transfer and the study of the flash vacuum pyrolysis of various cyclic and non-cyclic organic molecules related to, and including, o-allyltoluene

In the course of studying the flash vacuum pyrolysis (FVP) of tetralin, workers in the Trahanovsky group have observed evidence of the secondary pyrolysis of o-allyltoluene. Further studies on the FVP of o-allyltoluene yielded evidence consistent with a rearrangement involving diradicals formed by an uncommon thermally induced intramolecular hydrogen-atom transfer. To investigate the scope of this rearrangement, we have studied the FVP\u27s of several related alkylaryl olefins including o-allyltoluene-alpha,alpha,alpha- d3, (E/Z)-o-(1-propenyl)toluene, o-(1-methylallyl)toluene, o-allylethylbenzene, o-allylcumene, o-(3-butenyl)toluene, o-(4-butenyl)toluene, and 2-methylstyrene. Parallel studies on the phenol and aniline analogs of o-allyltoluene, were also performed. Additional studies on several cyclic and heterocyclic analogs of o-allyholuene, including 3-(o-tolyl)propene oxide, o-cyclopropylmethyltoluene, and o-cyclohexyltoluene were also performed.;Generally, FVP\u27s of o-allyholuene, o-allyltoluene-alpha,alpha,alpha- d3, o-(1-methylallyl)toluene, o-allylethylbenzene, o-allylcumene, o-allylphenol, o-allylaniline, o-(ethenyloxy)toluene, and o-(1-methylallyl)phenol all yield products whose formation is consistent with the existence of diradical intermediates produced by intramolecular hydrogen-atom transfer. The main reaction paths of the diradicals thus generated appear to be either coupling to form the respective five-membered carbocyclic or heterocyclic fused-ring systems or intramolecular disproportionation to form either starting material or the respective ortho substituted 1-propenylbenzene. No conclusive evidence was observed for the thermally induced intramolecular hydrogen-atom transfer in the epoxide, cyclopropyl, and cyclohexyl systems studied. However, some of the results showed unexpected selectivity for isomerization products, such as the selective isomerization of epoxides to aldehydes and the importance of the methyl position in the cyclohexyl systems

ERIS: revitalising an adaptive optics instrument for the VLT

ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that are now being maintained beyond their operational lifetimes, combine their functionality on a single focus, provide a new wavefront sensing module that makes use of the facility Adaptive Optics System, and considerably improve their performance. The instrument will be competitive with respect to JWST in several regimes, and has outstanding potential for studies of the Galactic Center, exoplanets, and high redshift galaxies. ERIS had its final design review in 2017, and is expected to be on sky in 2020. This contribution describes the instrument concept, outlines its expected performance, and highlights where it will most excel.Comment: 12 pages, Proc SPIE 10702 "Ground-Based and Airborne Instrumentation for Astronomy VII

Microalgae production in fresh market wastewater and its utilization as a protein substitute in formulated fish feed for oreochromis spp.

Rapid growing of human population has led to increasing demand of aquaculture production. Oreochromis niloticus or known as tilapia is one of the most globally cultured freshwater fish due to its great adaptation towards extreme environment. Besides, farming of tilapia not only involves small scales farming for local consumption but also larger scales for international market which contributes to a foreign currency earning. Extensive use of fishmeal as feed for fish and for other animals indirectly caused an increasing depletion of the natural resource and may consequently cause economic and environmental unstable. Microalgae biomass seems to be a promising feedstock in aquaculture industry. It can be used for many purposes such as live food for fish larvae and dried microalgae to substitute protein material in fish feed. The microalgae replacement in fish feed formulation as protein alternative seem potentially beneficial for long term aqua-business sustainability. The present chapter discussed the potential of microalgae as an alternative nutrition in fish feed formulations, specifically Tilapia
