Authors: Tisman Ulfana , Supriadi Supriadi
Published: July 2023

Cocor bebek is a plant that is easy to cultivate in Indonesia. This cocor bebek contains chemical compounds such as steroids, alkaloids, glycosides, tannins, and flavonoids which have antioxidant properties. Research on the analysis of flavonoid levels in the leaves of cocor bebek (kalanchoe pinnata) has been carried out using the UV - Vis spectrophotometric method. This research aims to determine the levels of flavonoids in the ethanol extract of cocor bebek leaves. The extract of chemical content in cocor bebek leaves was carried out by maceration method using 70 % ethanol. The flavonoid content of the sample extract was measured by measuring the absorption at wavelengths of 510 nm and 700 nm. The results obtained in the qualitative test showed that the cocor bebek leaf extract was positive for flavonoids which were characterized by a change in color from brownish red to green. The results of the quantitative test showed that the flavonoid content in the cocor bebek leaf extract was 0.321 mg / 100 g.

Authors: Rasheed Mona Al , Al-Ahmad Mona , Altourah Lulwa , Alzayer Ebrahim , Rodriguez Tito , Shalaby Neveen
Published: July 2023

Introduction: Thalassemia and myeloproliferative neoplasias (MPNs) are
two separate disease entities. Thal. is an inhereted congenital
hemolytic anemia caused by abnormal globin gene synthesis. MPNs are
acquired clonal hematopoietic stem cell diseases characterized by the
proliferation of different hematopoietic stem cells. The coexistence of
thal. and MPNS are rarely reported. Methods: We performed a
single-center retrospective analysis of all cases known to have thal.
including patients developing persistent high levels of hemoglobin or
platelet. The diagnosis of MPN was confirmed by genetic testing from
peripheral blood, bone marrow biopsy and blood film analysis. Results:
In this case series, we report six cases with coexistence of alpha(α),
beta(β) and delta-beta (δβ) thal. with different types of MPNs including
essential thrombocytosis ( ET ) and polycythemia vera. Majority of these
patients had positive Janus kinase (jak 2) mutation, except for one
patient with diagnosis of ET who had calreticulin (CALR) gene mutation.
Most of the patient in our case series are younger than average age for
the diagnosis of MPNs.

Authors: Li xiaoyu , Zeng Wenbo , Liang Huawei
Published: July 2023

In the actual traffic environment, there usually exists more than one
vehicle in the radiation area of the road-side units (RSU) at the same
time, and the front vehicle will affect the ray paths between the RSU
and the on-board units (OBU) of the back vehicle. Here we studied the
front vehicle’s impact on the ETC system’s path propagation loss by ray
tracing technology and Uniform Theory of Diffraction (UTD). Firstly, we
simplified the vehicle body structure into two equivalent geometric
models. We analyzed propagation loss models under line-of-sight (LOS)
and non-line-of-sight (NLOS) conditions based on the distance change
among RSU, OBU, and the front vehicle. Finally, a set of ETC
comprehensive testing equipment was developed to measure the
transmission loss of toll stations. Both simulation and experiment
results indicate that the propagation loss models proposed in this
letter are valid.

Published: July 2023

Soil erosion causes fluctuations in potato ( Solanum tuberosum L)
yield, deteriorates soil health, lowers profit margins for growers, and
creates adverse environmental impacts. This study focuses on developing
a decision support system to improve soil health, increase profitability
for growers, and lower environmental risks. Two fields are selected for
this research in Prince Edward Island, Canada, during 2020-2021. Thermal
and topography surveys are conducted to delineate fertility-based
management zones (MZs) for soil sampling of organic matter, potato
yield, and sensor data collection. Soil temperature are calibrated and
validated before the growing season using handheld gun and drone-based
thermal imagery. Data analysis from drone imagery reflects the coincided
patterns of thermal and multispectral imagery with crop yield,
topographical features, and soil water and topography (SWAT) maps.
Higher temperature zones lead to excessive soil erosion that reduces
soil surface nutrients, lower NDVI values, and show visual variation in
bare soil imagery. Moreover, it is found that low thermal zones produce
higher yields as compared to the high thermal zones. As such, the slope
has a direct impact on the retention of soil moisture content; the low
productivity zones retain the least soil moisture content (13.5%),
followed by medium (16.1%) and high productivity zones (18.4%). This
proposed decision support system can be a useful tool for mapping soil
erosion and crop profitability. The data generated from these tools can
be a crucial input for improved quantification of sediment transport in
watershed scale models.
Conservation genetics of Notelaea lloydii (Oleaceae) in south-eastern Queensland, Australia
Authors: Manawaduge Chapa , Ryan James , Phillips Matthew , Fuller Susan
Published: July 2023

Habitat fragmentation can increase the chance of population bottlenecks
and inbreeding, and may ultimately lead to reduced fitness and local
extinction. Notelaea lloydii is a native olive species endemic to
Australia and listed as vulnerable due to its restricted distribution. A
recent molecular systematics study has revealed there might be some
geographic structuring among the N. lloydii populations. Therefore, we
undertook a genome wide Single Nucleotide Polymorphism (SNP) analysis to
determine levels and patterns of genetic diversity, inbreeding and gene
flow within and among N. lloydii populations in south-eastern Queensland
(SE-QLD). Furthermore, as the reproductive phase of a plant’s life
history has a profound influence on genetic diversity, life history
reproductive traits were also studied. Our SNP analysis revealed low
genetic diversity, inbreeding and significant genetic structuring even
among proximate populations. Results of a flower and fruit bagging
experiment in two consecutive seasons revealed that N. lloydii produced
many flowers but only a few fruits survived to maturity. There were no
differences in bagged and un-bagged flowering and fruiting rates and
therefore, we conclude that the high fruit abortion rate was probably
due to inbreeding depression and/or suboptimal conditions, rather than
pollinator availability and insect attack. Overall, results of this
study indicate that the populations of N. lloydii are small, inbred and
genetically isolated and represent unique management units that require
local conservation management due to ongoing threats associated with
urbanisation.
Combined adaptive DRN-GRU model based on ultra short-term PV generation forecasting
Authors: Chen Xiangyu , Tian Guang , Zhao Jing , Jia Qingquan , wan jiaxin
Published: July 2023

Traditional deep neural network model training process will deepen the
network to a certain number of layers will produce network degradation
phenomenon, and then affect the training effect and prediction accuracy.
To address this problem, a PV power prediction model based on deep
residual network (DRN) and gated recurrent unit (GRU) neural network is
proposed. Firstly, the Pearson correlation coefficient method is used to
filter out the meteorological variables with high correlation with PV
power from historical data and reduce the data dimensionality. Secondly,
the DRN-GRU prediction model is proposed to be trained using the
adaptive learning rate Adam optimization algorithm to obtain the optimal
parameters. Finally, a DRN-GRU rolling prediction model is built based
on the historical data series to derive the PV power prediction results.
The results of the algorithm show that the model can still maintain good
training effect in the network training of deep numbers, effectively
solve the network degradation problem, and have higher prediction
accuracy compared with models such as artificial neural networks and
traditional convolutional neural networks.

Authors: Huang Zitong , Xu Yonghai , Chen Lin , Ye Xingjie
Published: July 2023

Faced with the uncertainty of wind and photovoltaic power output and
load fluctuation caused by the increase of new energy penetration in
active distribution network, the demand for operational flexibility and
the construction demand for flexible resources of distribution network
are gradually increasing. The flexible operation of active distribution
network can be realized by coordinated planning of the soft open point
integrated with energy storage system (ESOP) and flexible resources.
Firstly, the flexibility resource adjustability evaluation and margin
indicators are proposed for the response model of typical flexibility
resources. Secondly, a two-stage distributionally robust coordinated
planning model considering the coordination planning scheme of
distributed generation, flexibility resource and ESOP as well as the
comprehensive norm uncertainty of wind power and photovoltaic outputs
multi-operation scenarios is established with the distribution network
construction cost, annual operation cost and annual power sales revenue
as the objective functions meanwhile the investment and flexibility
resource operation as constraints. Finally, the column constraint
generation algorithm is used to solve the problem, and the effectiveness
of the proposed model is verified by the modified IEEE33 node system.
Thermal Anomaly Area Intelligent Recognition Method Based on Infrared Inspection Image of Electrical Equipment
Authors: Wang Laiqi , Ou Jianhua , Wang Jianguo , Hu Cong , Fan Yadong , Xie Fuhua
Published: July 2023

The thermal anomaly area of electrical equipment in the substation is
often hidden due to its small thermal area and multiple anomalies
overlaid. Accurately identify the thermal area is demanded on the
condition detection of electrical equipment, where the anomaly points of
electrical equipment in infrared images are generally small and of low
resolution. We propose an improved YOLOv4 algorithm for infrared image
anomaly area identification, which can detect the thermal generation
phenomenon of electrical equipment. We add a new target detection branch
to the shallow feature map of 104×104, which can better extract small
target semantic information. The training process is enhanced with
cosine annealing and mosaic data enhancement. We establish a total of
719 infrared images of five types of thermal anomalies electrical
equipment to test our network. The accuracy of our model reach to as
high as 96.78%, with a detection speed of 17 f/s and an AP@0.5 of
94.23%. Compared with SSD, YOLOv4 and Faster RCNN, the algorithm in
this paper obtains the highest AP@0.5 with 94.23%, which is the best
performance compared with the original YOLOv4 model in accuracy. The
model is robust to noise and luminance disturbances, and still provides
good recognition under disturbances.
Analysis of the influence of large-scale offshore wind power on the steady-state voltage of the vicinity region of grid connection point
Authors: Gao Weilun , Wu Zhigang
Published: July 2023

The power characteristics of offshore wind power will change the
regional power flow distribution and affect the regional voltage. In
this paper, the direct-drive wind turbine generator controlled by unity
power factor is selected as the research object, and the influence of
change of wind power on voltage at the grid connection point is analyzed
from the simple integration model. Based on the two critical states of
the external equivalent power of the grid connection point, an
analytical expression of the output of wind power in the corresponding
state is obtained, and the relationship among the critical state
outputs, the output of wind power and the parameters at the grid
connection point is drawn, hence the related influence laws is analyzed.
The influence of change of wind power on voltage and regional reactive
power and the reactance distribution of transmission lines near the grid
connection point is considered to analyze the influence of offshore wind
power on the vicinity region of grid connection point. The rationality
of the conclusion is verified by study the cases of the integration of
offshore wind power into Guangdong power grid, and some suggestions are
put forward for the planning of offshore wind power integration.
Genetic Predisposition of Vulnerable Groups to Schizophrenia and Bipolar I via AKAP11 Variant Analysis
Authors: Tillie Peyton , Sidhu Sohila , Hu Vivian , Mohamad Ali , Vollmer Elle
Published: July 2023

Recent exome sequencing analyses have shown that schizophrenia and
bipolar I disorder, collectively affecting 2% of the population, may
extend from a common genetic origin of the AKAP11 gene.  Though
several studies have been put forth to examine the relationship between
the pathogenesis of these mental illnesses and AKAP11 variants, a
model has yet to be created that tests this hypothesis by accounting for
real–world diagnosis frequencies in addition to a genetic framework. 
Analogously, no genetic study has been put forth to identify specific
vulnerable groups in the development of either schizophrenia or bipolar
disorder.  To provide additional insight into the pathogenesis of these
diseases, we perform ordinal logistic regression on every AKAP11
variant in the SCHEMA and BipEx data sets.  Primarily using the CADD
genome annotation, we establish the probability that each variant is
deleterious.  We use a chi–square goodness of fit test to demonstrate
that the amino acids coded for by high–risk variants are similar
between schizophrenia and bipolar disorder, suggesting a common
underlying genetic origin.  Additionally, a sequence of one–sided
t tests is run to compare the age and sex frequencies of these
high­–risk variants to the frequencies of schizophrenia and bipolar I
diagnoses among the Canadian population.  In total, we find that
AKAP11 exhibits a strong correlation with bipolar I disorder and
a moderate correlation with schizophrenia.  We also find that males
under 30 and females between 50 and 55 are most vulnerable to
schizophrenia and bipolar I, respectively.

Published: July 2023

OBJECTIVE

To study the relationships between artificial sweeteners, accounting for all dietary sources (total and by type of artificial sweetener) and risk of type 2 diabetes (T2D), in a large-scale prospective cohort.

RESEARCH DESIGN AND METHODS

The analyses included 105,588 participants from the web-based NutriNet-Santé study (France, 2009–2022; mean age 42.5 ± 14.6 years, 79.2% women). Repeated 24-h dietary records, including brands and commercial names of industrial products, merged with qualitative and quantitative food additive composition data, enabled artificial sweetener intakes to be accurately assessed from all dietary sources. Associations between artificial sweeteners (total, aspartame, acesulfame potassium [K], and sucralose) and T2D were investigated using Cox proportional hazard models adjusted for potential confounders, including weight variation during follow-up.

RESULTS

During a median follow-up of 9.1 years (946,650 person-years, 972 incident T2D), compared with nonconsumers, higher consumers of artificial sweeteners (i.e., above the sex-specific medians of 16.4 mg/day in men and 18.5 mg/day in women) had higher risks of developing T2D (hazard ratio [HR] 1.69; 95% CI 1.45–1.97; P-trend <0.001). Positive associations were also observed for individual artificial sweeteners: aspartame (HR 1.63 [95% CI 1.38–1.93], P-trend <0.001), acesulfame-K (HR 1.70 [1.42–2.04], P-trend <0.001), and sucralose (HR 1.34 [1.07–1.69], P-trend = 0.013).

CONCLUSIONS

Potential for reverse causality cannot be eliminated; however, many sensitivity analyses were computed to limit this and other potential biases. These findings of positive associations between artificial sweetener intakes and increased T2D risk strengthen the evidence that these additives may not be safe sugar alternatives. This study provides important insights in the context of on-going reevaluation of artificial sweeteners by health authorities worldwide.

Introduction

Penconazole (PEN) is a widely applied triazole fungicide. This study sought to define the efficacy of N-acetyl-l-cysteine (NAC) in mitigating PEN-triggered hepatorenal toxicity in rats.

Material and Methods

Twenty-eight adult male albino Wistar rats were assigned to four groups: a normal control (NC), a PEN group, a NAC group and a PEN+NAC group. Administration of PEN (50 mg/kg body weight (b.w.) every 2 days) and NAC (150 mg/kg b.w., daily) took place via oral gavage for 10 days.

Results

Effective amelioration by NAC of PEN-induced liver and kidney dysfunction was indicated by a significant reduction in the circulating liver and kidney markers (aspartate aminotransferase, alanine aminotransferase, urea and creatinine). Attenuation of PEN-induced oxidative stress and lipid peroxidation in liver and kidney tissues was evident in a significant reduction in malondialdehyde and enhanced total antioxidant capacity. Moreover, NAC significantly reduced the histopathological alterations and the expression of tumour necrosis factor α in liver and kidney tissue. Furthermore, NAC maintained the messenger RNA levels of nuclear factor erythroid 2-related factor 2 (Nrf2), haem oxygenase 1, and Kelch-like erythroid cell-derived protein 1 and prevented nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) protein upregulation caused by PEN.

Conclusion

N-acetyl-1-cysteine protected against PEN-induced hepatorenal oxidative damage and inflammatory response via activation of Nrf2 and inhibition of NF-κB pathways.

Introduction

The results are presented of the inter-laboratory validation of a liquid chromatography–tandem mass spectrometry method for the determination of eight mycotoxins (aflatoxin B1, deoxynivalenol, fumonisin B1, fumonisin B2, ochratoxin A, toxin T-2, toxin HT-2 and zearalenone) in animal feeds.

Material and Methods

This study was an essential part of the method’s transfer from the National Reference Laboratory to six regional laboratories in Poland working in the official survey of mycotoxins in feed. The laboratories received a batch of standard solutions, blank samples and quality control materials on which to perform analysis with one procedure and different liquid chromatography–tandem mass spectrometry conditions.

Results

The validation results show good precision (reproducibility coefficient of variation 3.7–20.5%) and accuracy of the method (recovery 89–120% and trueness 94–103%) and sufficient skills of the laboratory personnel.

Conclusion

The study is an example of the successful transfer of the method among laboratories.
Influence of composition of curing agent and sand ratio of engineering excavated soil on mechanical properties of fluidized solidified soil

Published: July 2023

With the continuous expansion of the urban scale, the development of engineering construction has been accelerated. In this process, excavated engineered soils produced in the construction process are facing the problem of difficult treatment. In this work, the influence of the composition ratio of different curing agents on the strength of fluidized solidified soil was studied. It was found that when the proportion of fly ash and quicklime in the curing agent was 1:1, and the percentage of the curing agent in the soil was 15%, the 28 days unconfined compressive strength of fluidized solidified soil reached the maximum value. When the composition and content of the curing agent and the slump of the fluidized solidified soil remained unchanged, the strength and water stability of the fluidized solidified soil increased with the increase of the sand ratio of the excavated engineered soil. X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) showed that with the increase of sand in the soil ratio, more needle-like ettringite crystals were produced in the fluidized solidified soil, which were more compact, had fewer voids, and had higher overall compactness. The carbon emissions of the prepared fluidized solidified soil and the common backfill materials were calculated, and it proved that the carbon emissions of the fluidized solidified soil were the lowest. Therefore, this work offers a new method for resource utilization of excavated soil and provides a carbon emission reference for green low-carbon building materials. Finally, it was recommended to choose engineered excavation soil with high sand content to obtain higher performance from fluidized solidified soil.
Elegant Tosakin Goldfish showcased in a Batik Shawl
Authors: Amelia Bunga
Published: July 2023

The Tosakin Goldfish, a unique Japanese variety known for its horizontally spread tail fin, is relatively unknown outside of Japan. Due to the limited information available, breeding and caring for these fish is considered challenging, resulting in few breeders. To promote awareness and understanding of the Tosakin Goldfish, artists have incorporated its image into batik shawls, using distilled waterlily plants and stones. The project, titled "Gemulai Tosakin Goldfish in Selendang Batik," aims to showcase the beauty and essence of the fish through five batik scarfs named "The Swaying Tail of Tosakin Goldfish on Batik Scarfs." The artistic process follows A.A.M. Djelantik's aesthetic approach, focusing on harmonizing form, context, and presentation. S.P. Gutami's theory of three stages and six steps guides the artwork creation process. The chosen technique, Colet Tempel, is rarely utilized in the batik industry, providing an opportunity to expand knowledge within the community. The scarves depict the Tosakin Goldfish amidst a background resembling a tranquil pond, complete with leaves, budding waterlilies, and pebbles. This artwork is expected to inspire and educate society, educational institutions, and the textile craft sector, paving the way for further exploration and appreciation.
