Optimization of Dehairing/Fiber Opening using Ammonium Chloride/Dispase by Response Surface Methodology
Authors: Tang Chao , Liu Hui , Hu Yadi , Wang Fang , Tang Keyong , Zhong Jide 
Published: December 2023

A great number of pollutants including sulfides, suspended solids, and ammonia nitrogen compounds are generated by dehairingand fiber opening with the traditional use of sodium sulfide, calcium hydroxide, and ammonium salt. In this work, ammoniumchloride (NH4Cl)/dispase system was used for the dehairing and fiber opening as an alternative of sodium sulfide/lime system tosimplify the beamhouse operations, as well as to ease environmental pollution. It was found that the removing effect of interfibrillar substance is highly related to the factors such as enzyme catalysis time, temperature and the salt usage. Therefore, the mathematical models of enzyme activity, protein content, polysaccharide content and hydroxyproline content were established by response surface methodology (RSM) with the enzyme catalysis time, temperature and the salt usage as independent variables. It was found that the dehairing/fiber opening effect is the best with 2 % NH4Cl (base onhide weight) at 32.5°C for 15h, and only 3.5 h is needed for dehairing. This work might provide a reference for green leather making with enzymes.

Published: December 2023

This letter proposes a low-complexity, two-step angle, range and delay
signature estimation algorithm for a sparse multipath near-field
spatial-wideband system. With upcoming sub-THz systems expected to have
a large number of antennas, the transmitted wideband signal is not only
sensitive to the physical propagation delay across the array aperture
but the resulting wavefront is no longer locally planar. We use a
combination of discrete linear chirp transform and discrete Fourier
transform based techniques to estimate the spatial wideband signature of
such a system. Further, we propose an iterative neighbourhood search to
acquire super-resolution estimates of the scatterer locations, delays
and angle of arrival of the multipaths and show that they are
asymptotically optimal approaching their respective CramÃ©r-Rao
bounds.Â This letter proposes a low-complexity one-snapshot two-step

A New Old Idea: Beam-Steering Reflectarrays for Efficient Sub-THz Multiuser MIMO
Authors: Tiwari Krishan Kumar , Caire Giuseppe 
Published: December 2023

This paper presents a novel, power- and hardware-efficient, multiuser,
multibeam RIS (Reflective Intelligent Surface) architecture for
multiuser MIMO,Â especially suited to operate in very high frequency
bands (e.g., high mmWave and sub-THz), where channels are typically
sparse in the beamspace and line-of-sight (LOS) Â is the dominant
component. The key module is formed by an active multiantenna feeder
(AMAF) with a small number of active antennas, placed in the near field
of a RIS with a much larger number of passive controllable reflecting
elements. We propose a pragmatic approach to obtainÂ a steerable beam
with high gain and very low sidelobes. Then K independently controlled
beams can be achieved by closely stacking K suchÂ AMAF-RIS modules. Our
analysis includes the mutual interference between the modules and the
fact that, due to the delay difference of propagation through the
AMAF-RIS structure, the resulting channel matrix is frequency selective
even in the presence of pure LOS propagation.Â We consider a 3D geometry
and show that “beam focusing” is in fact possible (and much more
effective in terms of coverage)Â also in the far-field, by creating
spotbeams with limited footprint both in angle and in range.Â Our
results show that: 1) Â simple RF beamforming without computationally
expensive baseband digital multiuser precoding is sufficient to
practically eliminate multiuser interference when the users are chosen
with sufficient angular/range separation, thanks to the extremely low
sidelobes of the proposed module; 2) the impact of beam pointing errors
with standard deviation as large as 2.5 degÂ and RIS quantized
phase-shifters with quantization bits > 2 is essentially
negligible; 3) The proposed architecture is more power efficient and
much simpler from a hardware implementation viewpoint than standard RF
beamforming active arrays with the same beamforming performance. As a
side result, we show also that the array gain of the proposed AMAF-RIS
structure grows linearly with the RIS aperture, in line with classical
results for standard reflector antennas.
Using (Counter)stories to (Re)shape our Communities and World(s)

Published: December 2023

Drawing upon my experience as a Canadian Muslim woman, scholar, educator, and mother, I share and inquire into my stories of experiences alongside youth. Thinking narratively (Clandinin, 2013), I weave my experiences using and teaching with/about single stories (Adichie) and counterstories (Lindemann Nelson, 1995) alongside students to (re)shape the multiplicity of ourselves (Lugones, 1987), relationships, and communities. This article will provide windows, mirrors, and sliding glass doors (Bishop, 1990) into my school and familial curriculum-making (Huber, Murphy, & Clandinin, 2011) experiences alongside Muslim youth. I hope that it will also provide insights into the experiences of diverse Muslim children, youth, and caregivers/families.

ABSTRACT

Integrated crop-livestock systems (ICLS) foster synergistic relationships to increase nitrogen (N) cycling and soil organic carbon (SOC) accrual in agricultural setups. This study evaluated how the grazing intensity and N fertilization (rates and timing) affect both SOC and N fractions, and soil organic matter chemical composition in an ICLS managed under no-tillage in an Oxisol, six years after initiation. The ICLS was compared to a nearby pasture (PA) and a native forest (NF). The treatments consisted of two grazing intensities: Low Sward Height (LH) and High Sward Height (HH) were maintained with high and low stocking rates, respectively. The HH varied between 0.20 and 0.60 m, and LH between 0.10 and 0.30 m according to the plant forage species throughout the experiment. Fertilization using 200 kg ha
-1
N-urea, not splitting up, was conducted at two timings, either at the winter pasture establishment (autumn), about 35 days after sowing or during the summer cash crop cycle (spring). Total N amount per year, including both phases, pasture and cash crop was the same for all treatments. The SOC and N contents were assessed in soil and particulate organic matter (POM), while carbon (C) and N stocks were specifically determined in the soil. Soil organic matter composition was characterized by FTIR. The combination of HH and N fertilization during the pasture phase increased the content of C from 36.1 to 39.9 ± 0.7 g C kg
-1
and of N from 2.7 to 3.2 ± 0.1 g N kg
-1
. The SOC stocks varied from 37.3 to 41.1 ± 0.7 Mg C ha
-1
, and the N stocks from 2.1 to 3.3 ± 0.1 Mg N ha
-1
at 0.0-0.10 m soil layer. The SOC content of the POM and the soil organic matter chemical composition determined by FTIR were mainly affected by the grazing intensity. The HH led to an increased in C content within the POM fraction, reaching values of 51.6 ± 1 and 49.2 g C kg
-1
, respectively to N crop fertilization and N pasture fertilization. Land-use changed how organic functional groups were stored in soil organic matter fractions. The NF had a greater abundance of aliphatic and phenol in the MAOM, while pasture and ICLS systems had greater aliphatic in the POM fraction. In ICLS, SOC accrual was positively associated with more recalcitrant organic functional groups of phenol, aromatic, and carbonyl C-O. The HH increases SOC accrual, while N-fertilization on pasture ensures adequate nutrition of plants and animals during the winter ICLS phase, at the same time as providing greater residual N for subsequent cash crops through enhanced catalyzed by ruminants. Therefore, grazing and fertilization management strategies should be considered to promote sustainable agriculture intensification with ICLS.
Estimation of soil organic carbon content by Vis-NIR spectroscopy combining feature selection algorithm and local regression method

Published: December 2023

ABSTRACT

Soil organic carbon (SOC) content is a critical parameter for evaluating soil health. However, high redundancy and invalid information in soil hyperspectral data can reduce the accuracy and stability of SOC prediction models. This study developed a global partial least squares regression (PLSR) model and a local PLSR model for agricultural soils in the LUCAS 2015 database. Some variable selection methods were combined with the regression models and their effects on prediction accuracy were explored. In addition, when the genetic algorithm is utilized for spectral feature selection, we obtained a more representative spectral subset through a novel coding approach. The results illustrated that the best SOC estimation accuracy was achieved by the local PLSR combined with a coding-improved genetic algorithm (GA), with R
2
of 0.71, RMSEP of 5.7 g kg
-1
, and RPD of 1.87. This study demonstrates that appropriate spectral band selection only slightly enhances the model performance of both global and local regressions, as PLSR models using the full spectrum show similar performance. Local PLSR models consistently outperform global ones using full spectrum or variable selection algorithms.

ABSTRACT

State parks are integral protection units created to protect ecosystems. However, anthropic activities may have been previously performed before their creation, forming transitional areas. Studies that evaluate the modifications of edaphic properties in these environments are scarce.

This article presents a data filtering system in high-precision positioning technology for the hull of a marine vessel in space, designed for use in a strapdown inertial navigation system. The goal of this research is to correct the raw data with subsequent stabilization of the high-precision positioning technology of the marine vessel. A comparative analysis of batch filters with the recursive Kalman filter was conducted to determine the true values for application in this concept. It is noted that high results in fault tolerance in the presence of external interference or in case of random loss of satellite signals increase the accuracy of the system for autonomous operation. The article proposes a methodology for applying an effective recursive filter within the structure of E-navigation. The result of this research is the leveling of final errors while eliminating the instability of certain accuracies and signal loss from key indicators. When using a series of incomplete and noisy measurements, an estimate of the variations of navigation elements describing the motion of the vessel's hull was obtained.

In today's world, there are numerous urgent global challenges that require our attention, prominent among those issues is the need to address climate change. Due to this, governments around the world have united in support of initiatives such as the Sustainable Development Goals, which seek to achieve a harmonious balance between development and the protection of the environment. The pivotal roles that environmental conservation measures, technical progress, and contemporary industrial strategies play are essential for the economic expansion of developing and industrialized countries in lowering CO2 emissions. Therefore, this study suggests that expanding green growth through the consumption of renewable energy is an effective strategy to mitigate CO2 emissions and achieve sustainable development, thus improving the contribution to environmental quality. Consequently, this research explores the long-term relationship between per capita CO2 emissions and economic development in 15 industrialized and developing countries with data spanning from 1991 to 2019. The present study employs PMG-ARDL estimation technique to rigorously examine the research objectives. The result shows that in the long run, both FDI and quadratic GDP significantly and negatively influence carbon emissions in industrialized nations. However, the other elements have a substantial positive and negative impact on climate change. The result also showed that increasing FDI reduces carbon emissions in industrialized countries. However, the opposite is true for emerging ones. Additionally, the findings of this article indicate that there is a considerable positive correlation between the use of fossil fuels and the progression of climate change in both developed and developing nations. Therefore, the findings of this research provide credence and legitimacy to the notion of the Kuznets curve when viewed and compared in the context of both emerging and developed economies.

Abstract
The right to criticize or parody has always been a fundamental human right. In today’s world of technology and the Internet, parodies or caricatures of someone’s work are not uncommon. Technology has become so readily available that anyone can create a parody or caricature of another person’s work. The main task of the nowadays researchers is find balance between one person’s right to the inviolability of his property and the right of other persons to imitate it.
The aim of this article is to analyze the concept of parody and caricature, as well as the case law of different countries – exploring how case law assesses whether an imitated work can be defined as a parody, or whether it is an “unsuccessful” imitation. Where is the line where an author has created a parody or has already infringed the rights of another author?
The methodological basis of this article is based on general scientific approaches (analysis and synthesis, deduction and induction, comparison, analogy and a systemic and structural-functional approach). The article also draws on court decisions, legislation, legal literature, publications and doctrine. Conclusions are drawn using the method of scientific induction and deduction.
