AbstractLeeches feeding on invertebrates are an important component of freshwater communities, including those dominated by fish, but the effects of Knitwear fish on their abundance and distribution are not well explored.The relative densities and assemblage structure of two leech families, Erpobdellidae and Glossiphoniidae, were studied from May t
Local Election often makes the bureaucratic Savings Bank apparatus face a dilemma, between being neutral or being involved in politics.Ideally and based on the rules of law, bureaucracy requeired to behave professional and neutral from politics.Despite that in reality it is difficult fot the bureaucratic aparatur to be neutral, moreover when they f
As an emerging paradigm in distributed power systems, microgrids provide promising solutions to local renewable energy generation and load demand satisfaction.However, the intermittency of renewables and temporal uncertainty in electrical load create Gifts great challenges to energy scheduling, especially for small-scale microgrids.Instead of deplo
In this paper, a miniature portable heart rate detector system is implemented by modern hardware ICs and simple sensor circuit with software executable on both PC and Android platform.The biosignal is first extracted via photoplethysmography Knitwear (PPG) principle into electric signal.Then a microprocessor is used to covert biosignal from analog
Simultaneous multiple-fracture treatments in horizontal wellbores have become one of the key methods for economically and efficiently developing oil and gas resources in unconventional reservoirs.However, field data show that some perforation clusters have difficulty propagating fractures due to the internal mechanism of competing initiation and pr
