Abstract:

An integrated energy system (IES) shows great potential in reducing the terminal energy supply cost and improving energy efficiency, but the operation scheduling of an IES, especially integrated with inter-connected multiple energy stations, is rather complex since it is affected by various factors. Toward a comprehensive operation scheduling of multiple energy stations, in this paper, a day-ahead and intra-day collaborative operation model is proposed. The targeted IES consists of electricity, gas, and thermal systems. First, the energy flow and equipment composition of the IES are analyzed,

Abstract:

Intra-day price spreads are of interest to electricity traders, storage and electric vehicle operators. This paper formulates dynamic density functions, based upon skewed-t and similar representations, to model and forecast the German electricity price spreads between different hours of the day, as revealed in the day-ahead auctions. The four specifications of the density functions are dynamic and conditional upon exogenous drivers, thereby permitting the location, scale and shape parameters of the densities to respond hourly to such factors as weather and demand forecasts.

At present, due to the errors of wind power, solar power and various types of load forecasting, the optimal scheduling results of the integrated energy system (IES) will be inaccurate, which will affect the economic and reliable operation of the integrated energy system.

In the day-ahead dispatching of network-constrained electricity markets, renewable energy and distributed resources are dispatched together with conventional generation.

Noise is word related to undesire sound which disrupts quality of life .when the noise present in ambience exceeds the prescribed limits is called as noise .Excessive noise disrupts day to day activity such as sleep, conversation. It is a type of pollutant which was earlier neglected but as the growth and development took place, excessive noise started to disturb human activity .this lead to identification, quantification and regulation of noise by WHO .the paper present the noise pollution data interpretation of two bus stations of Lucknow city in the month of February 2021.

POWER INDUSTRY DYNAMICS The concept of modern world is imperfect without electricity. The development of modern gadgets in past two decades has made human living as reflection of a science fiction movie. The fiction like living’s axis in fact is electricity and without electricity every thing comes to a grinding halt. Though this picture is portrait of the developed world, yet everyone would agree that wherever electricity has reached, it has transformed everything into power reliant.

Abstract:

SARS-CoV-2 outbreak led to unprecedented innovative scientific research to preclude the virus dissemination and limit its impact on life expectancy. Waiting for the collective immunity by vaccination, mass-testing, and isolation of positive cases remain essential. The development of a diagnosis method requiring a simple and non-invasive sampling with a quick and low-cost approach is on demand. We hypothesized that the combination of saliva specimens with MALDI-TOF MS profiling analyses could be the winning duo. Before characterizing MS saliva signatures associated with SARS-CoV-2 infection, op

Abstract:

The inflammation biomarker Interleukin 6 (IL-6) exhibits a concentration of less than 7 pg/mL in healthy serum but increases 10–100-fold when inflammation occurs. Increased serum IL-6 has been reported in chronic diseases such as rheumatoid arthritis (RA), as well as in life-threatening acute illnesses such as sepsis and cytokine release syndrome (CRS). This work seeks to meet the demand for rapid detection of serum IL-6 both for rapid monitoring of chronic diseases and for triaging patients with acute illnesses.

Introduction. Osteoarthritis of the knee joints is the most common joint disease affecting more than 80% of people over 55 years of age. The priority method for the treatment of gonarthrosis is the use of local injection therapy with the introduction of synovial ﬂuid endoprostheses based on hyaluronic acid, included in the Second Step of the ESCEO 2019 algorithm. Viscoelastic polyacrylamide gels for intra-articular administration since 2003 have also shown their high effciency in the symptomatic OA treatment.

It can be used post-partum irrespective of breastfeeding to improve birth spacing and reduce unintended pregnancy and maternal-child mortality. However, this method remains highly underutilized. Methods. We developed a multi-level intervention targeting supply, demand, and sustainability to increase uptake of the post-partum intrauterine device (PPIUD, defined as insertion up to six weeks post-delivery) in Kigali, Rwanda.

The two data-driven approaches learn the historical optimization results calculated out using the mixed integer linear programing (MILP) and conditional value at risk (CVaR), respectively.

Hydrogen and renewable electricity-based microgrid is considered to be a promising way to reduce carbon emissions, promote the consumption of renewable energies and improve the sustainability of the energy system. In view of the fact that the existing day-ahead optimal operation model ignores the uncertainties and fluctuations of renewable energies and loads, a two-stage energy management model is proposed for the sustainable wind-PV-hydrogen-storage microgrid based on receding horizon optimization to eliminate the adverse effects of their uncertainties and fluctuations.
