With the mass introduction of wind power in Northern China, wind power variability has appeared. In this article, both existing electric heat pumps (EHPs) and coal-fired combined heat and power (CHP) facilities, which are generally equipped with extraction-condensing steam turbines coupled with district heating for space heating purposes, are proposed to incorporate the variability of wind powe...

Combined heat and power (CHP) production is an increasingly important power production technology for efficient utilization of primary energy resources and for reducing CO2 emissions. In CHP plants, generation of heat and power follows joint characteristics, which means that production planning must be done in coordination. A CHP system may also comprise separate heat and power components to ma...

Environmental pressures have resulted in an increased importance being placed on the efficient production and consumption of energy. Micro combined heat and power ( CHP) technology has the potential to make an important contribution to make the transition to more sustainable energy systems since it is a highly efficient technology for generating both electricity and heat from a single fuel sour...

Idiopathic, nonspecific interstitial pneumonia (NSIP) is most often associated with various clinical disorders, including connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP). Emerging evidence also suggests that "idiopathic" NSIP may be the lung manifestation of undifferentiated CTD (UCTD). However, whether or not NSIP outcome is influenced by the underlying cause r...

Wind power has achieved great development in Northern China, but abundant wind power is dissipated, rather than utilized, due to inflexible electricity production of combined heat and power (CHP) units. In this paper, an integrated CHP system consisting of CHP units, wind power plants, and condensing power plants is investigated to decouple the power and heat production on both the power supply...

The virulence of the opportunistic pathogen Pseudomonas aeruginosa involves the coordinate expression of many virulence factors, including type IV pili, which are required for colonization of host tissues and for twitching motility. Type IV pilus function is controlled in part by the Chp chemosensory system, which includes a histidine kinase, ChpA, and two CheY-like response regulators, PilG an...

Female infertility and low birth rate are significant public health issues with profound social, psychological, and economic consequences. Some infertile women resort to conventional, complementary, or alternative therapies to conceive. The aim of this study was to identify the Chinese herbal products (CHPs) most commonly used for female infertility in Taiwan. The usage of traditional Chinese m...

Owners of combined heat and power (CHP), e.g., industrial manufacturers, are motivated to provide frequency response grids due clear financial benefits. Yet, the slow speed CHP limits its capability in providing such services. Moreover, frequent adjustments would cause a faster lifetime reduction rapid pressure fluctuation gas network. To further unlock flexibility CHP, this article integrates ...

BACKGROUND In early vertebrate development, embryonic tissues modulate cell adhesiveness and acto-myosin contractility to correctly orchestrate the complex processes of gastrulation. E-cadherin (E-cadh) is the earliest expressed cadherin and is needed in the mesendodermal progenitors for efficient migration. Regulatory mechanisms involving directed E-cadh trafficking have been invoked downstrea...

Bone is able to adapt its composition and structure in order to suit its mechanical environment. Osteocytes, bone cells embedded in the calcified matrix, are believed to be the mechanosensors and responsible for orchestrating the bone remodeling process. Recent in vitro studies have shown that osteocytes are able to sense and respond to substrate strain and fluid shear. However the capacity of ...
