Model and application of annual river runoff prediction based on complementary set empirical mode decomposition combined with particle swarm optimization adaptive neuro-fuzzy system
Authors: Guo Huifang , Chen Lihui , Fang Yuan , Zhang Shixia 
Published: March 2023

Abstract

Runoff is affected by natural and nonnatural factors in the process of formation, and the runoff series is generally nonstationary time series. How to improve the accuracy of runoff prediction has always been a difficult problem for hydrologists. The key to solve this problem is to reduce the complexity of runoff series and improve the accuracy of runoff prediction model. Based on the aforementioned ideas, this article uses the complementary set empirical mode decomposition to decompose the runoff series into multiple intrinsic components that retain time–frequency information, thus reducing the complexity of the runoff series. The particle swarm optimization (PSO) adaptive neuro-fuzzy system is used to predict each intrinsic component to improve the accuracy of runoff prediction. After that, the trained intrinsic components of the model are reconstructed into the original runoff series. The example shows that the absolute relative error of the runoff forecasting model constructed in this article is 0.039, and the determination coefficient is 0.973. This model can be applied to the annual runoff series forecasting. Comparing the prediction results of this model with empirical mode decomposition algorithm-ANFIS model and ANFIS model, complementary set empirical mode decomposition algorithm-PSO-ANFIS model shows obvious advantages.
Removal of dissolved organic matter from the woodchip bioreactor start-up by foam fractionation

Abstract
Denitrifying woodchip bioreactors are passive, low-tech systems primarily designed to remove nitrate from shallow ground waters as well as point source discharges. Despite their capacity to achieve constant nitrate removal over several years, natural aquatic environments may be affected by the leaching of dissolved organic matter (DOM) from fresh woodchips during start-up. Simple on-site measures might reduce the woodchip leachate during start-up and thus add to the overall environmental sustainability of woodchip bioreactor installations. The aim of the study was to investigate whether foam fractionators could provide an effective solution. Water was flowed through fresh laboratory-scale woodchip bioreactors and recirculated through foam fractionators for 11 days. The bioreactors removed nitrate but increased phosphate and ammonia, which were not effectively removed via foam fractionation. However, foam fractionation did remove 37.8 ± 4.7% of the dissolved chemical oxygen demand (CODdiss) leached during the first 11 days of operation. Fluorescence spectroscopy revealed that the DOM composition differed between the foam and water, where the foam fraction contained higher amounts of DOM associated with the highest bioavailability and hence the greatest potential environmental impact. Optimised foam fractionators could therefore help to reduce the environmental impact of DOM leachate from woodchip bioreactors during start-up.

Authors: Karakaya Muhammed Fatih , Gokalp Faik , Sener Erol , Korkmaz Orhan Tansel 
Published: March 2023

Aims:
Flavonoids naturally exist in plants as secondary metabolites. In this study, the
aim is to determine and compare the theoretical and in vivo chemical activities of 7,8-
dihydroxyflavone (7,8-DHF) and 4'dimethylamino-7,8-dihydroxyflavone (4’-DMA-7,8-DHF),
tyrosine receptor kinase B (TrkB) receptor agonist flavonoid molecules with reported potent neuroprotective
effects.

Methods:
The density functional theory (DFT) (RB3LYP) method was used for the theoretical
chemical analysis. For the in vivo studies, 6-month-old Wistar rats were used in two groups
(n=8). 7,8-DHF and 4’-DMA-7,8-DHF (5 mg/kg) were administered intraperitoneally (ip) to
each group. Then, plasma samples were collected by carotid catheterization, and brain samples
by the microdialysis technique were collected simultaneously for 12 h from awake rats. The level
of 7,8-DHF and 4’-DMA-7,8-DHF in blood and brain samples were analyzed and their pharmacokinetics
were determined.

Results:
Theoretical calculations show that 7,8-DHF is slightly more stable than 4’-DMA-7,8-
DHF. The in vivo pharmacokinetic results show that the maximum concentration of 7,8-DHF was
about 48 ng/mL, whereas it was only 8 ng/mL for 4’-DMA-7,8-DHF.

Conclusion:
Our results suggest that the 4'-DMA-7,8-DHF is more unstable and is more prone to
binding to TrkB than 7,8-DHF. On the other hand, the in vivo pharmacokinetic results show that
7,8-DHF is more stable than 4’-DMA-7,8-DHF when it is applied systemically at therapeutic
concentrations.
EFFICIENCIES IN POWER PLANT
Authors: Wang Yun 
Published: March 2023

INTRODUCTION
In thermodynamics, several major devices related to energy conversion are
introduced, including the internal combustion engines (ICE), steam turbine,
boiler, heat exchanger, and heat pump. Thermal efficiency is a dimensionless
performance measure of these devices. In general, thermal efficiency is the
fraction of energy addition in the form of heat or thermal energy converted to
useful output, as shown in Fig. (6.1), given as a percentage value. The
nominally Otto-cycle ICE in automobiles can reach about 30% efficiency at
the flywheel. Rankine-cycle steam turbine thermal efficiency can be as high as
41%. In heat pump cycles where heat rejection in the high-temperature side is
the useful output, the efficiency is usually defined as the ratio of the rejected
heat to the compressor work input, commonly called the coefficient of
performance (COP). Refrigeration moves heat from a confined space and
dissipates it in the atmosphere. Heat pumps move heat from one spot (often
from the atmosphere or underground) to a home of business. Residential
refrigerators and air conditioners are based on a vapor-compression
mechanical refrigeration cycle. The former generally has a COP over 1 in
practice, while the latter may have a COP over 3 to 5. The COP of heat pumps
is generally higher than that of their refrigerator counterparts.
REFRIGERATION
Authors: Wang Yun 
Published: March 2023

INTRODUCTIONRefrigerators and air conditioners are popular and important devices in our
daily lives. The former provides a low-temperature environment to store food
and drink, while the latter reduces the indoor temperature to a comfortable
level. In nature, we observe that heat flows from a higher temperature toward
a lower temperature. To reverse the heat flow from a low to high temperature,
mechanical work needs to be added to enable mechanical refrigeration, by
which a low-temperature environment is created for food saving or air
conditioning. The most important feature of mechanical refrigeration is its high
efficiency, usually called the coefficient of performance (COP): the COP of
residential refrigerators is usually above one, and air conditioners can achieve
even five. While other refrigeration methods have been developed, based on
different physical principles, such as vortex tubes and thermoelectric coolers,
their efficiencies, in general, are much less than one, and we use them for
special applications where their other characteristics make them attractive.
REPORT PREPARATION
Authors: Wang Yun 
Published: March 2023

OVERVIEWTo formally document a laboratory experiment, a written technical report is
prepared. However, it should be noted that detailed lab notes compiled during
the experiment are essential, so they can be used later in the full written report.
The overall goal for any laboratory report is to summarize an experiment
efficiently for an intended audience. Therefore, knowing who will read the
laboratory report (e.g. researchers in a similar field in a technical journal,
business leaders in a company as an internal white paper, or the general public
for mass consumption) will dictate the style, the tone and the level of technical
jargon needed in the written work. After identifying the target audience, the
lab report should explain the purpose of the experiment, the research questions
answered, the experimental procedures, the data observed, the analysis method
and the results.
Introduction: The Afterlives of Data
Authors: Murphy Brian Michael , Paulsen Kris 
Published: March 2023

Guest edited by scholars Brian Michael Murphy (Bennington College) and Kris Paulsen (The Ohio State University), this special issue entitled Afterlives of Data features articles, interview, artist projects, and reviews that address the ways the material conditions of data and art are shifting, and how thinkers, artists, and scholars can offer crucial scaffolding for understanding how we arrived here. The issue presents prehistories of data models we take for granted and provides historical contexts that clarify what is new and what is not, helping us to see where we now might be headed. NFTs, DNA data, the sensuous traces of e-waste, facial recognition software trained on marginalized subjects, and the institutionalized processes of dispossessing human subjects from their colonial contexts all present ways in which data comes to have an afterlife that haunts our present and potential futures.

Barriers to and attitudes towards the use of safety engineered devices for paediatric cannulation in emergency care
Authors: Martinez Rachel 
Published: March 2023

ABSTRACTThis article describes a report of the attitudes towards and barriers to the use of safety cannulas in paediatric patients. The evaluation was prompted by a lack of engagement from both doctors and nurses who continued to use non-safety-engineered devices (non-SEDs) after safety-engineered devices (SEDs) were introduced into a paediatric emergency department (ED). A survey was conducted among doctors and nurses working in the paediatric ED with questions focusing on the participants’ clinical experience, views on safety, access to training and device preference, providing both quantitative and qualitative data. The findings highlighted several issues, including a difference in opinion between professional groups towards safe sharps. Significant differences in access to training and education between doctors and nurses were also identified; including those with up-to-date training appearing more likely to use a SED than those without. Recommendations including strategies for improving compliance have been proposed, with a plan to conduct a clinical audit to measure compliance at a later date.
