Comprehensive treatment technology of scale in Fowa pump station of Xinjing Coal Mine

open access: yesMeikuang Anquan, 2021
Aiming at the problem that the fouling of the equipment at the Fowa pump station in Xinjing Coal Mine caused serious gas extraction inefficiencies, a comprehensive study on the scale control technology of the pumping station was carried out. A treatment

Study on scale inhibition properties of chitosan derivatives [PDF]

open access: yesE3S Web of Conferences, 2023
The chitosan derivatives scale inhibitor CTS-AMPS was synthesized by using chitosan and 2-acrylamido-2-methylpropane sulfonic acid as raw materials and ammonium persulphate as initiator, and the structure of the product was determined by ATR-FTIR.

Gain control with A-type potassium current: IA as a switch between divisive and subtractive inhibition [PDF]

open access: yes, 2018
Neurons process information by transforming barrages of synaptic inputs into spiking activity. Synaptic inhibition suppresses the output firing activity of a neuron, and is commonly classified as having a subtractive or divisive effect on a neuron's ...

Synthesis of MA-SAS-HEMA terpolymers and their scale inhibition properties

open access: yesXi'an Gongcheng Daxue xuebao, 2023
In order to solve the problem of water pollution caused by traditional phosphorus-containing scale inhibitors, a phosphorus-free MA-SAS-HEMA copolymer scale inhibitor was prepared by aqueous solution free radical polymerization using maleic anhydride (MA)

Punishment sensitivity predicts the impact of punishment on cognitive control [PDF]

open access: yes, 2013
Cognitive control theories predict enhanced conflict adaptation after punishment. However, no such effect was found in previous work. In the present study, we demonstrate in a flanker task how behavioural adjustments following punishment signals are ...

Thalamic Inhibition: Diverse Sources, Diverse Scales [PDF]

open access: yesTrends in Neurosciences, 2016
The thalamus is the major source of cortical inputs shaping sensation, action, and cognition. Thalamic circuits are targeted by two major inhibitory systems: the thalamic reticular nucleus (TRN) and extrathalamic inhibitory (ETI) inputs. A unifying framework of how these systems operate is currently lacking.

Scaling Up Cortical Control Inhibits Pain [PDF]

open access: yesCell Reports, 2018
Acute pain evokes protective neural and behavioral responses. Chronic pain, however, disrupts normal nociceptive processing. The prefrontal cortex (PFC) is known to exert top-down regulation of sensory inputs; unfortunately, how individual PFC neurons respond to an acute pain signal is not well characterized.

Handedness and behavioural inhibition:left-handed females show most inhibition as measured by BIS/BAS self-report [PDF]

open access: yes, 2008
This study investigated the relationship between handedness, gender and behavioural approach and inhibition using Carver and White’s (1994) BIS/BAS Scale. 112 participants took part: 46 left-handers and 66 right-handers. All participants completed Peters’

Synergistic scale inhibition of both IA/AMPS copolymer and magnetic field [PDF]

open access: yesE3S Web of Conferences, 2021
The antiscaling rate of both water magnetic device and IA/AMPS copolymer was investigated by using a stationary scale inhibition experimental device, and the result illustrated that there was a synergistic scale inhibition effect between magnetic field ...
