Authors: Střížek Antonín , Přibyl Pavel , Lukeš Martin , Grivalský Tomáš , Kopecký Jiří , Galica Tomáš , Hrouzek Pavel
Published: December 2022

Background
Algae are prominent producers of carotenoids and polyunsaturated fatty acids which are relevant in the food and pharmaceutic industry. Fucoxanthin represents a notable high-value carotenoid produced exclusively by algae. Its benefits by far exceed antioxidant activity and include anti-diabetes, anti-obesity, and many other positive effects. Therefore, large-scale microalgae cultivation to produce fucoxanthin and polyunsaturated fatty acids is still under intensive development in the industry and academic sectors. Industrially exploitable strains are predominantly derived from marine species while comparable freshwater fucoxanthin producers are missing.
Results
In this study, we searched for freshwater fucoxanthin producers among photoautotrophic flagellates including members of the class Chrysophyceae. The initial screening turned our attention to chrysophyte alga Hibberdia magna. We performed a comprehensive cultivation experiment using the temperature × light cross-gradient to assess the impact of these conditions on the target compounds productivity. We present the observations that H. magna simultaneously produces fucoxanthin (max. 1.2% dry biomass) and polyunsaturated fatty acids (max. ~10% dry biomass) and is accessible to routine cultivation in lab-scale conditions. The highest biomass yields were 3.73 g L-1 accompanied by maximal volumetric productivity of 0.54 g L-1 d-1 which are comparable values to marine microalgae fucoxanthin producers in phototrophic mode. H. magna demonstrated different optimal conditions for biomass, fucoxanthin, and fatty acids accumulation. While maximal fucoxanthin productivities were obtained in dim light and moderate temperatures (23ᵒC × 80 µmol m-2 s-1), the highest PUFA and overall biomass productivities were found in low temperature and high light (17-20ᵒC × 320-480 µmol m-2s-1). Thus, a smart biotechnology setup should be designed to fully utilize H. magna biotechnological potential.
Conclusions
Our research brings pioneer insight into the biotechnology potential of freshwater autotrophic flagellates and highlights their ability to produce high-value compounds. Freshwater fucoxanthin-producing species are of special importance as the use of sea-water-based media may increase cultivation costs and it is not feasible for inland microalgae production.
Case report: A case of welder’s lung with end stage pulmonary fibrosis
Authors: Baur Xaver , Abraham Jerrold L.
Published: December 2022

Background
Welding which as performed regularly by more than a million workers worldwide is associated with exposures to irritative, fibrogenic and carcinogenic fumes and gases.
Methods and Results
We present the case of a welder who had worked under extremely poor hygiene conditions for nearly 20 years and had developed end-stage lung fibrosis, finally requiring lung transplantation. Detailed histopathology and Scanning Electron Microscopy/Energy dispersive x-ray spectroscopy (SEM/EDS) analysis of his lungs showed advanced interstitial fibrosis and dust deposits in the lungs and in peribronchial lymph nodes containing welding type bodies, Fe, Si (silica), Ti (titanium), SiAl (aluminum silicates), Fe with Cr (Steel), Zr (Zirkonium).
Conclusion
Due to these severe findings, the absence of a systemic disorder and the failure to meet the criteria for diagnosis of idiopathic pulmonary fibrosis (IPF), the most likely diagnosis of this case is welder’s lung fibrosis.
Assessing brain states with two-photon calcium signals
Authors: Tort-Colet Núria , Resta Francesco , Montagni Elena , Pavone Francesco , Allegra-Mascaro Anna-Letizia , Destexhe Alain
Published: December 2022

Brain states, such as wake, sleep, or different depths of anesthesia are usually assessed using electrophysiological techniques, such as the local field potential (LFP) or the electro-encephalogram (EEG), which are ideal signals for detecting activity patterns such as asynchronous or oscillatory activities. However, it is technically challenging to have these type of measures during calcium imaging recordings such as two-photon or wide field techniques. Here, using simultaneous two-photon and LFP measurements, we demonstrate that despite the slower dynamics of the calcium signal, there is a high correlation between the LFP and two-photon signals taken from the neuropil outside neuronal somata. These results suggest that calcium signals alone can be used to detect activity patterns such as slow oscillations and ultimately assess the brain state.

Published: December 2022

The problem of management and treatment of wastewater from commercial laundries is a matter of concern. The present study provides an effective and eco-friendly solution to the treatment of wastewater from commercial laundries in Quebec (Canada) by using extracellular polymeric substance (EPS) as bio-flocculant. EPS was produced from valorization of crude glycerol and paper mill sludge by a bacterial strain (BS-04). Two different types of EPS: Slime EPS (S-EPS) and Broth EPS (B-EPS) were used for treatment of commercial laundry wastewater (CLWW). This is the first study for treatment of CLWW using bio-flocculant EPS. A comparison between the conventional treatment of laundry wastewater (LWW) by chemical coagulants (FeSO4, CaCl2, Alum) and enhanced treatment by bio-flocculant EPS has been drawn in the study. Moreover, LWW treatment by combination of EPS and chemical coagulants was also investigated. It was observed that S-EPS (0.6 g/L) gave better flocculation activity (FA) than B-EPS. S-EPS alone can remove 83.20% of turbidity, 77.69% suspended solids (SS) and 76.37% chemical oxygen demand (COD). The best results were obtained by combining S-EPS (0.6 g/L) together with alum (300 mg/L) at pH 7 for treatment time of 30 min. This combination was able to remove 98% of turbidity, 95.42 % of SS and 83.08% of COD from LWW. When treatment time has been increased to 4 h at pH 7, it resulted in more than 88% COD removal from CLWW.
Roles of electrostatic interactions in the peroxide systems for bleaching of cotton fiber
Authors: Fu Jiangpeng , Du Jinmei , Miao Dagang , Xiao Guowei , Jiang Yang , Xu Changhai
Published: December 2022

The industrial bleaching of cotton fiber is often carried out
in an aqueous solution of hydrogen peroxide
(H2O2) with the addition of sodium hydroxide
(NaOH) at a boiling temperature. In order to overcome the higher
energy consumption problem of the H2O2/NaOH
system, activated peroxide systems are proposed by adding so-called
bleach activators to the H2O2 solution in
which bleach activators can react with H2O2
to generate more kinetically active bleaching species enabling
cotton fiber to be bleached at lower temperatures. In previous
studies, most researchers focused their attention on the chemical
behaviors of bleaching species. In this paper, it was found that
the electrostatic interactions between bleaching species and cotton
fiber might be played an important role in the peroxide systems for
bleaching of cotton fiber. In order to disclose the effects of
electrostatic interactions on the bleaching performance, cotton
fiber was modified with 3-chloro-2-hydroxypropyltrimethyl ammonium
chloride (CHPTAC) which changed the negative surface charge of
cotton fiber to positive one, and bleached with the
H2O2/NaOH system and activated peroxide
systems that generated bleaching species with various ionic
charges. It was found that the electrostatic attraction between
bleaching species and cotton fiber contributed to improving the
bleaching performance, but the electrostatic repulsion between
bleaching species and cotton fiber undermined the bleaching
performance. The addition of a neutral electrolyte (e.g. NaCl) and
ionic surfactants to these bleaching systems could give rise to
similar charge effect. Hence, the findings in this work provide
further understanding that the performance of the peroxide systems
for bleaching of cotton fiber depends not only on the chemical
activities of the bleaching species but also on the electrostatic
interactions between the bleaching species and cotton fiber.

Published: December 2022

Objective
To analyze the efficacy of multidisciplinary treatment (MDT) for Wilm’s tumor (WT) in Kunming Children’s Hospital, and investigate the risk factors affecting the prognosis of WT.
Method
The clinic-pathological data were collected and analyzed in patients with unilateral WT treated in Kunming Children's Hospital from January 2017 to July 2021. Research objects were selected according to inclusion criteria and exclusion criteria. The risk factors and independent risk factors that affect the prognosis of patients with WT were determined by Kaplan-Meier survival analysis and Cox proportional hazards model, respectively.
Outcome:
A total of 68 children were included in this study, and the 5-year overall survival (OS) rate was 92.65%. Kaplan-Meier survival analysis results showed that ethnicity (P = 0.020), the tumor volume of resection (P = 0.001), histological type (P < 0.001), and postoperative recurrence (P < 0.001) were the factors affecting the prognosis of children with WT. The results of the Cox proportional hazards model showed that only the histological type (P = 0.028) was the independent risk factor for the prognosis of WT.
Conclusion
The efficacy of MDT for WT was satisfying. The histological type has important predictive value for the prognosis of WT, and the patient with unfavorable histology has a poor prognosis.
Correlation of serum sodium,serum potassium concentrations and their ratios with blood pressure in older patients
Authors: Li Jingjing , Li Gang
Published: December 2022

Background
Several studies have investigated the relationship between dietary or urine potassium and sodium and blood pressure, but few have evaluated the relationship between serum potassium or sodium and blood pressure. Therefore, we evaluated the association between serum potassium and sodium and blood pressure in an older Chinese population.
Methods
A total of 241 older patients admitted to Hebei General Hospital were consecutively enrolled. 150 patients were divided into hypertension group and 91 patients were divided into normal blood pressure group. Correlation analysis and multiple logistic regression were used to analyze the relationship between serum sodium, serum potassium and their ratio with blood pressure. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum sodium/potassium ratio for hypertension in this population.
Results
Serum potassium was negatively correlated with systolic blood pressure (r=-0.341, P < 0.001), serum sodium-to-potassium ratio was positively correlated with systolic blood pressure (r = 0.349, P < 0.001), and serum sodium was not significantly correlated with systolic blood pressure (r = 0.105, P < 0.001). Serum sodium/potassium concentration ratio (OR = 1.094, 95%CI 1.003–1.193, P = 0.043) was still an independent influencing factor of hypertension. The area under ROC curve of serum sodium-to-potassium ratio for predicting hypertension in older patients was 0.666 (95%CI 0.599–0.733, P < 0.001).
Conclusions
Serum potassium level is related to blood pressure in the older population, and serum sodium-to-potassium ratio is related to hypertension in the older patients, which is an independent risk factor for hypertension in this population.

Published: December 2022

Background: Home healthcare (HHC) is an important care choice for elderly people with disabilities; however, the risk factors for emergency department (ED) visits, a poor outcome index, remain unclear. Therefore, we conducted this study to clarify it.
Methods: We conducted a case-control study from a medical center in Taiwan by identifying HHC patients between Aug 1, 2019, and July 31, 2021. Age, sex, iatrogenesis, underlying comorbidities, and ED visit data were collected. Univariable and multivariable logistic regression analyses were performed to identify independent predictors of ED visits.
Results: We identified 240 patients, including 133 patients with and 107 patients without ED visits, for this study. The mean ages were 83.9 and 83.3 years and females accounted for 71% and 60.9% of patients without and with ED visits, respectively. Multivariable logistic regression analyses showed that urinary catheters (adjusted odds ratio [aOR]: 5.84; 95% confidence interval [CI]: 1.48−23.01, p = 0.012) and peptic ulcer disease (PUD)/gastroesophageal reflux disease (GERD) (aOR: 2.27; 95% CI: 1.12−4.61, p = 0.023) were independent predictors of ED visits. Stratified analyses according to sex and age showed that PUD/GERD and dyslipidemia were significant predictors of ED visits in female patients.
Conclusions: This study identified independent predictors of ED visits in HHC patients. Our results provide an important reference for the early prevention, recognition, and adjustment of care plans for at-risk patients. Further studies recruiting more patients and external validation are warranted.

Published: December 2022

The utilization of the altimetric satellite’s on-board radiometer for atmospheric observation is demonstrated. This study uses the Wet Tropospheric Correction (WTC) data from the Topex/Jason altimetry mission series (Topex/Poseidon, Jason-1, Jason-2/OSTM, and Jason-3). The data spans nearly 30 years, making them sufficient for climate study. Precipitable Water Vapor (PWV) is derived from the WTC and used to study the water vapor variability over the Tropical Indian Ocean (TIO). Standard EOF (Empirical Orthogonal Function) analysis on the derived PWV anomaly (PWVA) in the TIO generates two leading modes. The first mode has a dipole spatial structure that explains 18.3% of the total variance, and the second one has a basin-wide homogeneous structure that explains 12.3% of the total variance. Correlation analysis with IOD and ENSO monitoring indices has shown that these two modes are associated with the two interannual variabilities. Further analyses using composite techniques are done to distinguish the different of mechanism and impact between the two. A new monitoring index is proposed here which uses the altimetry-derived PWV anomaly data. The index is computed from the difference of PWV anomaly between the dipole regions in TIO, which effectively describes the activity of the Indian Ocean Walker Circulation (IOWC). This research showcased the feasibility of using the data measured by the radiometer of altimetric satellites for atmospheric studies, a potential continuation of this research would be the use of the synchronous altimeter-radiometer measurement for more advanced analysis such as the ocean-atmosphere coupling.

Published: December 2022

Introduction

In the past decade, podcasting has become an increasingly utilized form of asynchronous education amongst medical trainees. Medical education podcasts increase accessibility of novel literature, provide entertainment and promote community. Data on the impact of medical student-run podcasts is limited. The UnsCripted Medicine Podcast (UMP) is a medical student-run podcast created to provide near-peer support, promote academic success, and strengthen sense of belongingness. This study examined UMP listener self-reported behaviors, enjoyability, and podcast efficacy as a comradery-building tool.

Methods

A voluntary, seventeen-question survey was disseminated to all medical students at the University of Cincinnati College of Medicine. The survey utilized Likert scale items, multiple choice, multiple answer and open-ended formats. Descriptive statistics were used for analysis.

Results

143 (n = 19.5%) responses were received. Most respondents had listened to either 3–5 or 5–10 episodes (n = 51 or 41.8% and n = 36 or 29.5%, respectively). Most listeners consumed curriculum-related episodes (n = 109, 89.3%). 96% (n = 96 of 100) of listeners reported an increased sense of preparedness for courses, and 76.8% (n = 76 of 99) of listeners reported reduced stress. The UMP was considered enjoyable (n = 112 of 116, 96.5%) and was associated with an increased sense of belonging within the medical school community (n = 68 of 116, 58.6%).

Discussion

Medical student-run podcasts provide novel opportunities to increase near-peer mentorship within undergraduate medical education. They show promise in decreasing stress, increasing preparedness and increasing sense of belonging. Given the increasing popularity of podcasting in medical education, student podcast initiatives should be supported by medical schools.
An Approach Based on Deep Learning for Recognizing Emotion, Gender and Age
Authors: Nippon Nippon Datta , Juel Juel Sikder
Published: December 2022

At the same time, recognizing the emotions, gender and age of a person is a vital issue in real life. This research focuses on identifying the emotions along with age and gender of different ages male, female, common gender and children. In this study, a modified convolutional neural network (M-CNN) has been proposed for feature extraction where classification is followed by a Multi Support Vector Machine (M-SVM). Instead of detecting the face, a head-detecting technique is also used in the prediction part. To detect the head we proposed a system using the You Only Look Once Version 3 (YOLOV3) network. It helps to extract the feature from the whole head instead of the only face. Three datasets named AR-2022, FER-2022 and GR-2022 are introduced in this study. We also include the common gender in our datasets. In the case of age classification, we categorized the age datasets into 11 categories depending on the similarity of their features, gender into 3 categories and emotions into 7 categories. Our proposed model is compared with other existing models and current research, where the proposed model gives better accuracy and the accuracy of classification of emotions, age and gender are 97.47%, 98.43% and 96.65% respectively.
WITHDRAWN: Non-interference patterns evolving to interference patterns --- variation of Poisson-Arago spot experiment
Authors: peng hui
Published: December 2022

Young’s double slit experiment and Poisson/Arago spot experiment revived the wave theory of the light. The standard interpretation is that the light behaves as waves. Feynman called the double slit experiment the only mystery in quantum mechanics. Recently, the photon chamber has been proposed and utilized to study the behavior of photons near the detecting screen. The experiments show that the light, near the screen, behaves as photons propagating along the straight-line trajectories, and the trajectories distribute as waves. Furthermore, the photon chamber experiments show that, within certain macroscopic distance from the double slit, the pattern is non-interference, which indicates that the standard double slit experiments violate the standard wave interpretations. In this article, we show, the first time, that, within certain macroscopic distance from the ring, the pattern is non-interference, and how the non-interference pattern (near the ring) evolving to the interference pattern (far from the ring).
The experiments show: (1) the nature of the patterns is distance-dependent; (2) to certain macroscopic distance from the ring, the light beams behave as particle; (3) when the distance increases, the non-interference pattern evolves to the interference pattern, i.e., the non-wave nature and the wave distribution coexist in the same wave experiment. The experiments: (1) provide novel phenomena/data for further theoretical development of the optics and for understanding the nature of the light.

Efficient flow equations for dissipative systems
Authors: Schmiedinghoff Gary , Uhrig Götz S.
Published: December 2022

Open quantum systems provide an essential theoretical basis for the
development of novel quantum technologies, since any real quantum system
inevitably interacts with its environment. Lindblad master equations
capture the effect of Markovian environments. Closed quantum systems can
be treated using flow equations with the particle conserving generator.
We generalize this generator to non-Hermitian matrices and open quantum
systems governed by Lindbladians, comparing our results with recently
proposed generators by Rosso et al. (arXiv:2007.12044). In comparison,
we find that our advocated generator provides an efficient flow with
good accuracy in spite of truncations.
Comparison of buffalo’s, sheep’s and goat’s yoghurts in terms of their antioxidant activity, angiotensin-converting enzyme (ACE) inhibitory activity, volatile compound content and 5-hydroxymethylfurfural (HMF) content
Authors: TERZİOĞLU MURAT EMRE , BAKIRCI İHSAN
Published: December 2022

This study examined yoghurt samples produced using classical yoghurt culture from buffalo’s, goat’s and sheep’s milks in terms of their physicochemical characteristics, DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging activity, angiotensin-converting enzyme (ACE) inhibitory activity, and contents of total phenolic compounds (TPC), volatile compounds and 5-hydroxymethylfurfural (HMF). It was determined that the use of different types of milk in yoghurt production had a statistically very significant effect (p <0.01) on all physicochemical and biochemical properties analyzed, whereas the storage period had a very significant effect (p <0.01) on pH and titratable acidity. Compared to other types of milk, sheep’s milk was found to be superior in terms of antioxidant activity and ACE inhibitory activity, whereas buffalo’s milk was found to be superior in its content of volatile compounds. The highest HMF formation was observed in yoghurt samples produced from goat’s milk. It is therefore suggested that the consumption of yoghurts produced from different types of milk should be expanded because of their nutritional value and bioactivity.
Efficacy of an internal teat sealant alone or in combination with an intramammary antibiotic during the dry period treatment in dairy cows
Authors: ÖNEY MEHMET , KARADAĞ M.A. , D. KAYA
Published: December 2022

In this study, the aim was to determine the effectiveness of internal teat sealant applied at the dry-off in preventing the formation of subclinical mastitis and to investigate whether this product could be a non-antibiotic alternative to total dry cow treatment. A total of 195 quarters from 52 Holstein and Holstein Crossbreed dairy cows, that did not have clinical mammary infection and were expected to calve within 60 days were used in the study. The quarters were divided into 3 treatment groups as follows: Group 1 (ANTB; n = 64): dry period intramammary antibiotic suspension (Ubrostar®); Group 2 (ORB; n = 65), internal teat sealant (Orbeseal®); and Group 3 (ANTB-ORB; n = 66) intramammary antibiotic and teat sealant combination were performed. All of the quarters were checked for subclinical mastitis on the 20th, 40th and 60th days of lactation. The percentage of animals found to be CMT negative on the 20th day of lactation was 80.65% in G1 (ANTB), 83.60% in Group 2 (ORB), and 87.50% in Group 3 (ANTB-ORB), respectively. There was no quarter with CMT +3 score in G1 and G3, but it was determined in one quarter in G2 (ORB). On the 60th day there were no quarters with CMT +2 and +3 scores in both G1 and G2. No statistically significant difference was found between the CMT results of treatment groups on the 20th, 40th and 60th days of lactation (p > 0.05). In conclusion, it was determined that bismuth subnitrate-based teat canal sealer provided good protection against subclinical mastitis rate in drying healthy udder quarters. However, especially in high risk groups it is important to closely monitor udder health with SCC and/or CMT applications before the dry period and to choose the dry period treatment.
Foot-and mouth disease and peste des petits ruminants – the role of wildlife in the epidemiology and control of diseases
Authors: NIEDBALSKI WIESŁAW , FITZNER ANDRZEJ , KĘSY ANDRZEJ
Published: December 2022

Foot-and mouth disease (FMD) and peste des petits ruminants (PPR) are highly contagious and an economically devastating diseases, currently endemic to the African and Asian continents. The aim of this paper was to present the role of wildlife in the epidemiology of both diseases. There are more than 100 species of wild, feral, laboratory, or domesticated animals that have been infected naturally or experimentally with FMD or PPR viruses. Experimental infections of several African wild ruminants can result in clinical FMD. African buffalo represents the best known FMD wild host reservoir in Sub-Saharan Africa. North American mule deer were found susceptible to FMDV infection with significant mortality. Other wild ruminants such as impala can also contribute to FMDV maintenance. In Europe several deer species and the Eurasian wild boar are susceptible to FMDV. PPRV has been reported to have infected some wildlife, such as African buffalo, saiga antelope, dorcas gazelles, gemsbok, Nubian ibex and some other ungulate species. The role of wildlife in FMD and PPR epidemiology may concern wildlife as indicators, victims, bridge hosts or maintenance hosts for both diseases. In addition, they are occasionally victims of disease outbreaks, and they are often relevant for disease management as either bridge or maintenance hosts. Wildlife deserves to become a key component of future integrated surveillance and disease control strategies in an ever-changing world. However, it must be stated that efforts to control FMD and PPR in wildlife may not be successful when the diseases are endemic in livestock and may cause more harm to wildlife, human livelihoods, and domestic animals.
Fish as a source of foodborne bacteria
Authors: KOBUSZEWSKA ALEKSANDRA , WYSOK BEATA
Published: December 2022

A significant part of the global population depends on fish for both survival and health. However, as industry and agriculture expand rapidly, more and more natural and artificial aquatic ecosystems become contaminated. It may not only have an impact on the health of fish, but also raise safety concerns regarding the human consumption of fish. Although fish and fish products are well known to have a great nutritional value, it is crucial to be aware of the risk associated with their consumption, as they are among the main sources of foodborne bacteria.
Factors influencing economic benefit of rainwater harvesting: an empirical analysis
Authors: Islam M. Rafiqul
Published: December 2022

This study examines key factors influencing the economic benefit of rainwater harvesting on the household at the Mongla Upazila in the Bagerhat district of coastal Bangladesh. The household survey questionnaire was used to collect primary data from 1040 households. The Ordinary Least Square (OLS) regression analysis was applied to understand the relationship between economic benefit and factors that can affect economic benefit in the household. The empirical result shows that income (1.103**), storage capacity (0.574***), water price (32708.9***), age of rainwater harvesting (100.083***), and total cost (1.627***) positively impact economic benefit while the number of children (35.531**) has a negative relationship. The finding confirms the validity of statistical hypotheses. In addition, heterogeneity analysis was employed to test the model's strength and robustness check to validate the structural function and efficiency of the regression model. The finding concludes with policy recommendations, especially for rain-intensive countries that focus on (i) formulating and implementing rainwater harvesting policy; (ii) integrating rainwater harvesting as a tool for poverty reduction and achieving sustainable development goals; (iii) minimizing mismanagement of (rain) water that causes floods; (iv) initiating programmes and taking the necessary steps for providing financial and non-financial incentives for rainwater harvesting in commercial, and non-commercial buildings.
Enhanced ammonium removal from aquatic systems by a novel copolymer
Authors: Taha Hazem F. , Gad Waseem Ahmed , El-Hussein Ibrahim
Published: December 2022

A novel copolymer was used as an adsorbent for enhanced ammonium removal in an aqueous system; different ratios of styrene–acrylic acid copolymers were synthesized by random free radical polymerization and followed by a sulfonation of styrene (acrylic acid 25%–sulfonated styrene 75%) copolymer [P(AA25/SS75)] attained the highest ammonium adsorption capacity (55.8 mg/g) due to the electrostatic attraction between positively charged NH4+ and negatively charged –COO− and –SO3- groups. FTIR spectra for sulfonated polymers illustrated the appearance of characteristic peaks at 100–1200 cm−1 indicating that the copolymers were successfully sulfonated. The influence of different experimental factors (i.e., contact time, pH, NH4+ concentration, adsorbent dose) on ammonium ion adsorption was investigated; three adsorption isotherm models including Langmuir, Freundlich, and Temkin were used to study the adsorption mechanism. The results indicated that the equilibrium of adsorption can be reached within 30 min; the highest adsorption capacity can be achieved around pH 7. Furthermore, Freundlich isotherm was the most suitable for fitting the experimental data which might expose the heterogeneity of the adsorbent surface. The regeneration and reusability studies were also implemented, and results showed that P(AA25/PSS75) was stable and regenerable using (1 M) sulfuric acid as a desorbing agent over five cycles.
Crítica genética/epigenética y poéticas

Published: December 2022

En este artículo me propongo demostrar que el instrumental teórico de la crítica genética puede servir para analizar la variación pretextual/epitextual como el resultado de un proceso complejo de negociación entre fuerzas públicas y privadas una vez que la obra sale a la luz. El análisis de un manuscrito de Luis Cernuda (1982-1963), algunos publitextos de Hernán Bravo Varela (1979) y Coreografía del miedo, de Stephanie Alcantar (1990), expone las complejas relaciones entre obras muy diferentes que coinciden en una noción extendida del texto como proceso. Se trata de un enfoque novedoso que permite presentar el complejo diálogo entre los estados privados y públicos de una obra (entre sus reescrituras a través de distintas tradiciones e, incluso, entre sus interpretaciones) hasta su irrupción en las poéticas más recientes.

Authors: Sakr Samer , Al Khatib Ali , BouRaad Roland , Karaki Nadine , El Said Hassan , Sheet Imtithal , Hamam Bassam
Published: December 2022

Background:

Since its first emergence in Wuhan-China in the late 2019 to date, the coronavirus disease 2019 (COVID-19) has become the biggest public health threat on an international scale. Vaccination remains the first line of defence against the widespread of the virus.

Objective:

We aim to assess the socio-demographic association with knowledge, attitude and practice (KAP) towards the different COVID-19 vaccines in young Lebanese population.

Method:

This cross-sectional study conducted in Lebanon between January 24th and 31st 2021. 1350 respondents answered this questionnaire. Questions included four dimensions (11 Socio-demographic characteristics, 22 knowledge questions, 5 attitude questions and 5 related to the practices). One-way ANOVA was used to analyse the differences between the KAP variables with the socio-demographic variables. When significant differences were found (p-value < 0.05), Duncan’s Multiple Range test was applied to determine the significant differences between the means.

Results:

The average knowledge about COVID-19 vaccines among our participants is 52.88%; 52.81% showed a good attitude towards the different type of vaccines, and 53.98% demonstrated good practices. The socio-demographic variables having a significant influence on the knowledge and practices towards the COVID-19 vaccines were the living place, the educational level, the school in which the students belong to, the type of job (health-related or non-health related job) and the income range. The type of insurance that respondents have was significantly associated with practices but not with knowledge.

Conclusion

This study showed significant differences in KAP among Lebanese people regarding COVID-19 vaccines, mainly affected by gender, education, work field and income. Our findings reflect fair knowledge, positive attitudes and good practices towards COVID-19 vaccine among the Lebanese population. Consequently, the Ministry of public health must work harder to disseminate, in higher frequency, more accurate information about the vaccines, and organize more vaccination campaigns in order to increase trust in the vaccines efficacy and to decrease the public hesitation.
The conception of religious moderation in interfaith dialogue in Indonesia; Case study in Flores Nusa Tenggara Timur
Authors: Djainudin Hamdhan
Published: December 2022

This article discusses the concept of religious moderation in interfaith dialogue in Indonesia, especially in Flores, NTT. Religion, which in general is an ideology that is defensive and partial, at first glance does not appear in the Flores NTT community. This can be seen when commemorating religious holidays such as Eid al-Fitr or Christmas, where young people from different religious backgrounds help each other in the smooth implementation of the holiday, houses of worship that are often built side by side facilitate the process of interfaith interaction in Flores, NTT. This is an interest for the author to look further into the concept of religious moderation in Flores, NTT which can become an example in the application of religious moderation in Indonesia. Interpretive paradigm, an inductive qualitative approach, with qualitative multimethods, anthropology - ethnography to phenomenology, the author tries to map interfaith interaction patterns in the concept of religious moderation in NTT, where the result is, the position of religion as an ideology is replaced with the family, where the family is more exalted than religion, on the other hand the role of religious leaders is very large in the process of interfaith dialogue, cultural elements, customs that are humanistic in nature strengthen the process of interfaith interaction in Flores, NTT.
Net Zero UK – Generation and Energy Storage Requirements for the UK to Become Carbon Neutral
Authors: Williams Andrew , Thomson Murray
Published: December 2022

This paper sets out a quantified scenario for the UK to reach net zero carbon emissions. Wind and solar are the main energy sources and their intermittency is accommodated through hydrogen electrolysis, biogas from anaerobic digesters, and their combination into biomethane. Hydrogen and biomethane stocks are tracked. A daily energy balance model is presented, using the most recent recorded weather data-2017 to 2021. Long periods of low wind in 2021 indicated the necessary energy storage capacities, which were adjusted relative to energy generation capacities so as to achieve an economic minimum cost. The projected levelized cost of electricity is £92/MWh (which is well below the current energy wholesale price of £130) though this does assume greatly improved thermal insulation of most UK buildings. A 10% reduction of this cost is shown to be possible through the application of demand side management (retiming of energy consumption) thus illustrating the value of such flexibility. Carbon capture and storage (CCS) applied to power stations running on the biomethane could provide up to 21 Mt of negative emissions to offset other sectors, imports and even remove some of the excess emissions that have already occurred. The work goes beyond previously published scenarios: energy pricing is calculated, demand response measures have been modelled, and embedded carbon in imported goods is considered. The Python model is available, open-source, for inspection and further development.

Published: December 2022

Between 1 January 2021 and 1 July 2021, 120 blood samples from acute myocardial infarction (AMI) patients—60 as controls and 60 patients—of both sexes who were accepted to the cardiac surgery unit at AL- Salam teaching hospital, the intensive cardiac care unit, and outpatient clinics in Mosul City/Iraq, were taken. In the presented research, the ejection fraction regarding patients with AMI was evaluated by echocardiography, and the blood-liver enzyme levels (ALP and AST \ ALT ratio) were examined in those patients. The findings indicate that patients with AMI in the age range of 35 to 45 years have a (52.41) % ejection fraction (EF) rate, which is closer to (51.344%) than it is in samples from healthy controls. In addition to that, findings indicate that patients in an age range of 46 to 56 years have heart failure with a mid-range EF (HFmrEF), with a (48.13%) percentage, whereas this heart failure type in healthy controls has been preserved ejection fraction (HFpEF) with (53.368 %). In the case of the comparison of the AST/ALT ratio and EF across all of the age groups that have been tested, the results suggest a significant level (P ≤ 0.050) relation between the ALP enzyme and EF for the patients within the (35-45 years) age group additionally, as there has been a positive and weak linear connection (r = 0.10650) and a nominal p-value (p = 0.47240) at a threshold of probability ≤ P 0.050, the link and correlation between the AST/ALT ratio and cardiac EF have been investigated.

Published: December 2022

The experiments were conducted in fields of the department of animal production- agriculture college – Tikrit University by adding different levels of onion and sumac to the quail dietary and know its effect on the chemical composition of the thigh and the percentage of some saturated and unsaturated fatty acids and measures the peroxide value. The quail was divided into five treatments: Treatment1 was controlled without adding, treatment 2 (3.5)g/kg of onion added, Treatment 3 (7)g/kg of onion added, treatment 4 (5)g/kg of sumac added. Treatment 5 (10)g/kg of sumac added. The results showed a high percentage of moisture in treatment 3 (73.08) % compared with the others; also, treatment 4 showed significant differences in fat percentage (7.50)% to the others. No significant differences led to protein and ash percentages between the five treatments. Regarding saturated fatty acids, treatments 1 and 4 showed significant differences in palmitic acid (7.98, 7.01)%, respectively. Stearic acid was high in treatment one than the others (9.10)%. Regarding saturated fatty acids didn’t notice significant differences between the five treatments, but about peroxide, the values in treatments 2, 3, 4 and 5 were lower than the control.

®
30 (NN-Asp30).
Materials & methods:
In a randomized open-label, active-controlled, 26-week non-inferiority clinical trial 264 patients with Type 2 diabetes mellitus were randomized 1:1 to receive once-daily GP-Asp30 or NN-Asp30. The primary safety end point was the immune response rate. Efficacy outcomes were a mean change in HbA1c (primary), frequency of achieving a glycemic g fasting plasma glucose levels, 7-point glucose profiles, and insulin doses.
Results:
The immune response developed in 10/126 (8%) participants in the GP-Asp30 group and in 10/125 (8%) participants in the NN-Asp30 group (p = 1.000). The mean difference in HbA1c change between groups was 0.12 (95%CI [-0.14, 0.38]). Other secondary efficacy and safety outcomes weren't statistically different between the two groups.
Conclusion:
GP-Asp30 demonstrated similar safety and efficacy compared with NN-Asp30 and may be considered a biosimilar insulin.
