Demand response provides an opportunity for consumers to play a significant role in the operation of the electric grid by reducing or shifting their electricity usage during peak periods in response to time-based rates or other forms of financial incentives. Demand response programs are being used by some electric system planners and operators as resource options for balancing supply and demand. Such programs can lower the cost of electricity in wholesale markets, and in turn, lead to lower retail rates. Methods of engaging customers in demand response efforts include offering time-based rates such as time-of-use pricing, critical peak pricing, variable peak pricing, real time pricing, and critical peak rebates. It also includes direct load control programs which provide the ability for power companies to cycle air conditioners and water heaters on and off during periods of peak demand in exchange for a financial incentive and lower electric bills.
The electric power industry considers demand response programs as an increasingly valuable resource option whose capabilities and potential impacts are expanded by grid modernization efforts. For example, sensors can perceive peak load problems and utilize automatic switching to divert or reduce power in strategic places, removing the chance of overload and the resulting power failure. Advanced metering infrastructure expands the range of time-based rate programs that can be offered to consumers. Smart customer systems such as in-home displays or home-area-networks can make it easier for consumers to changes their behavior and reduce peak period consumption from information on their power consumption and costs. These programs also have the potential to help electricity providers save money through reductions in peak demand and the ability to defer construction of new power plants and power delivery systems -- specifically, those reserved for use during peak times.
One of the goals of the Smart Grid R&D Program is to develop grid modernization technologies, tools, and techniques to utilize demand response and help the power industry design, test, and demonstrate integrated, national electric/communication/information infrastructures with the ability to dynamically optimize grid operations and resources and incorporate demand response and consumer participation. To attain this goal, OE is supporting research, development and deployment of smart grid technologies, distribution system modeling and analysis, transactive energy, consumer behavior modeling, and analysis and high speed computational analysis capabilities for decision support tools
By using automated processes, reducing staff intervention, and letting smart fulfillment find the suppliers that meet your criteria, you achieve significantly faster turnaround times and reduce costs associated with document delivery and interlibrary loan.
These smart fulfillment benefits are the result of ongoing feature enhancements across OCLC resource sharing services, such as WorldShare Interlibrary Loan, Tipasa, and ILLiad. If you use these services, some of the features are already available at no additional cost.
In this study, we report the realization of drug-loaded smart magnetic nanocarriers constituted by superparamagnetic iron oxide nanoparticles encapsulated in a dual pH- and temperature-responsive poly (N-vinylcaprolactam-co-acrylic acid) copolymer to achieve highly controlled drug release and localized magnetic hyperthermia. The magnetic core was constituted by flower-like magnetite nanoparticles with a size of 16.4 nm prepared by the polyol approach, with good saturation magnetization and a high specific absorption rate. The core was encapsulated in poly (N-vinylcaprolactam-co-acrylic acid) obtaining magnetic nanocarriers that revealed reversible hydration/dehydration transition at the acidic condition and/or at temperatures above physiological body temperature, which can be triggered by magnetic hyperthermia. The efficacy of the system was proved by loading doxorubicin with very high encapsulation efficiency (>96.0%) at neutral pH. The double pH- and temperature-responsive nature of the magnetic nanocarriers facilitated a burst, almost complete release of the drug at acidic pH under hyperthermia conditions, while a negligible amount of doxorubicin was released at physiological body temperature at neutral pH, confirming that in addition to pH variation, drug release can be improved by hyperthermia treatment. These results suggest this multi-stimuli-sensitive nanoplatform is a promising candidate for remote-controlled drug release in combination with magnetic hyperthermia for cancer treatment.
It is a critical responsibility of leadership to see problems, to articulate them clearly, and to point a way for a solution. It seems like a simple dictum. However, when tough times come to a business, denial sometimes seems comforting. You, as the owner or manager of an independent bookstore, are already working very hard and may feel as though you are barely able to keep on top of the demands of your store now. When sales start a sustained and significant decline, a typical reaction may be to pretend it isn't really happening. Denial is very comforting right up until the point you go under.
Please understand that you have no choice. Lower sales volume demands a smaller inventory. However, now is an opportunity to retrain and refocus your staff on offering and taking special orders. Make sure that every time a customer asks for a title that you don't carry, your staff dedicates themselves to getting that customer that book. Call other independent bookstores and redirect the customer. Order more frequently from wholesalers. Get your staff together and brainstorm how to talk to your customers and to go the extra mile for them.
We estimated our sales by section for the next three months and calculated a goal level of inventory for each section based on their assigned turnover. Then, we printed out our actual inventory section levels, using our computerized inventory control system, and compared our inventory goals with the actual, existing inventory levels. We were able to target specific sections that were over-inventoried for returns. It also told us sections where the inventory had gotten too low. But, mainly, it gave us the monthly discipline to get our inventory as tight and as smart as possible. Cash is king, and smart inventory control is your key to the kingdom.
Finally, smart business owners frequently revisit their pricing policies. Bookstore owners are no different, especially during tough economic times. Neither ABA nor I can tell you how you should price your merchandise; every business sets its own prices. However, it's always important to analyze your competitive position in your marketplace. It may or may not be the right time to reduce your discounts or to reduce the number of books you discount. I have no advice on how you should price your merchandise, but I do believe that it is a good business practice to take a close look at all the financial aspects of your business.
Ask yourself where you will find that $30,000. Reduce your profit goals. Reduce expenses. Reduce payroll dollars through attrition. Take the pressure off your accounts payable by reducing your inventory in a smart way. Cover your cash needs with a line of credit. It may be that a temporary goal for your business becomes survival rather than profitability.
But, most of all, work with your staff on how your business can improve for your customers and for them. Listen and lead. Don't just be a cheerleader, but be a player and take smart action. Sure, you may make mistakes -- above my desk hangs a quote, "Fall down six times, get up seven" -- but you will ensure that your bookstore survives.
A smart grid is an electricity network that uses digital and other advanced technologies to monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end users. Smart grids co-ordinate the needs and capabilities of all generators, grid operators, end users and electricity market stakeholders to operate all parts of the system as efficiently as possible, minimising costs and environmental impacts while maximising system reliability, resilience, flexibility and stability. Most of the technologies involved have already reached maturity, and so tracking investments provides insights on levels of deployment.
While the transmission grid is already well-digitised, digitalisation of the distribution grid is still lagging in many countries, limiting the availability of real-time information. Despite the deployment of residential smart meters having advanced in recent years and even having reached 100% in some economies, such as China, the share is still very low in many countries.
The distribution sector accounts for around 75% of all investment in grid-related digital infrastructure, through the rollout of smart meters and the automation of substations, feeders, lines and transformers via the deployment of sensors and monitoring devices.
International partnerships in the area of smart grids address specific needs of the systems across the world, with the main goal of sharing knowledge and best practices on technologies and business models, and discussing the results of implementation in each partner country within the network. Programmes focus on developing engagement between countries to co-operate on the creation of international standards for smart grids, on stimulating manufacturers to develop and export their smart grid products, and also on increasing user acceptance.
