Assessment of the effectiveness biophysical soil and water conservation structures: A case study of Kiramuworeda, East Wollega Zone, Ethiopia
Authors: Fayera Tasfaye
Published: August 2023

Soil erosion is one of the most serious global environmental issues affecting agriculture and soil fertility. On a global scale, water erosion is the most common type of soil erosion in agricultural areas, reducing the soil's ability to support productive agriculture. The efficiency of biophysical soil and water conservation systems must be evaluated before solutions for limiting soil losses may be considered. To promote sustainable land use in the study area, it is critical to understand farmers' knowledge of soil and water conservation structures, as well as the factors that influence their land management practices. Farmers in the study region are well-informed about soil and water conservation structures in general, as well as their causes, indications, and the amount of their plot of land that is susceptible to soil erosion in particular. Furthermore, they feature both traditional and modern soil conservation structures that are successful. However, several impediments to implementing the Soil and Water Conservation structures were found, including a lack of finance, the small area of their land, and other socio-economic and physical aspects. Furthermore, farmers had a highly positive attitude regarding the importance of contemporary Soil and Water Conservation structures. Their awareness, on the other hand, appears to be incorrect. Because they believe that the present SWC Structure is a government-led initiative to rehabilitate highly degraded areas rather than a mechanism of soil and water conservation on agricultural land. They believe that the structures take up a huge portion of a relatively small plot of land, preventing them from properly utilizing it. As a result, it is suggested that the government's policies and strategies, as well as corrective intervention from non-governmental organizations aimed at this issue and community participation in encouraging farmers to participate in soil and water conservation practices, are critical to resolving current poverty, food insecurity, and environmental degradation in the study area.

Authors: Nguyen Huu Hieu , Phan Anh , Le Anh Tuan , Nguyen Thi Ngoc Anh
Published: August 2023

Purpose. Study of thermodynamic properties of acryloyl chloride to predict the danger if the acryloyl chloride is extinguished by water.
Methods. Thermodynamic properties (including enthalpy, free energy, entropy and heat capacity at constant pressure) of acryloyl chloride at vapor phase at 1.0 atm pressure and temperature range from 298.15 to 1000.00 K in steps of 100.00 K are determined by DFT calculations using PBEPBE functional. As the basis set 6-311G++(d,p) is used.
Findings. Free energy, and heat of reaction between acryloyl chloride and water in the fire (at the same temperature range and pressure) have been calculated. In temperature range from 298.15 to 1000.00 K, the reaction between acryloyl chloride and water is exothermic. So, if firefighters use water to fight the fire of acryloyl chloride, a large amount of heat will be released. This heat makes the fire is more dangerous and difficult to fight.
Application field of research. The results of research can be used in prediction the hazard of burning of acryloyl chloride and ways of extinguishing it.

Published: August 2023

Purpose: To evaluate the effect of the Active Sentry handpiece of the Centurion Vision System compared to the Centurion Ozil handpiece for phacoemulsification in cataract surgery.Methods: A retrospective study was conducted on 281 patients (449 eyes) who underwent cataract surgery between August 2020 and June 2021. Preoperative measurements, intraoperative parameters, complication rate, and postoperative outcomes were compared between the Active Sentry handpiece and the Centurion Ozil handpiece groups. Additionally, the parameters were compared in different cataract severity groups and multiple predictive factors for the number of active surge mitigation (ASM) actuations were assessed with the Active Sentry handpiece.Results: There were 198 eyes in the Active Sentry group and 251 eyes in the Centurion Ozil group. There were no statistically significant differences between the two groups, as the cumulative dissipated energy in the Active Sentry and Centurion Ozil groups were 8.32 ± 7.74 and 7.87 ± 9.25 μJ, respectively (p = 0.576). Total surgery time, ultrasound usage time, aspiration time, amount of fluid aspirated, postoperative corrected distant visual acuity, and postoperative decrease in corneal endothelial cell density were comparable between the two groups. The significant contributors to the number of ASM actuations were age, preoperative corrected distant visual acuity, axial length, and total ultrasound time.Conclusions: There was no clear advantage of the Active Sentry handpiece compared to the Centurion Ozil handpiece. ASM actuation increases with age, poor visual acuity before surgery, short axial length, and prolonged ultrasound usage time. It is expected that in more severe and high-risk cataract surgery, the Active Sentry handpiece functions more effectively, possibly affecting the safety and prognosis.
Readability of Australian Road Safety Information for the General Public
Authors: Ferguson Catherine , Winn Stephen
Published: August 2023

This research was conducted as a result of the authors becoming aware of the Australasian College of Road Safety (ACRS) submission to the National Road Safety Strategy 2021-2030. The ACRS submission outlined six key elements, one of which suggested that the National Road Safety Strategy should include 'Publication in easily consumable form, for the public, of infrastructure safety star ratings for all road users' (ACRS, 2021, p.61). This prompted the researchers to consider the road safety information provided to the general public about driving behaviour. Forty excerpts from online data from one Australian State's road safety website were assessed for readability using an online tool. Fifteen additional excerpts from another three States were assessed to ensure consistency across Australia. Results indicated that the excerpts assessed were written at a readability level that is too high for almost half of the Australian public. Recommendations include that those producing road safety information consider the level of literacy across the general public and ensure that their work becomes increasingly accessible to more Australians. The limitations of readability are acknowledged in relation to the overall communications which often include pictures and/or diagrams.

Published: August 2023

Tuberculosis (TB), rightly referred to as an ancient disease, has affected humans for thousands of years, the first drafted reference of which came from India and China around 3,300 and 2,300 years ago, respectively. TB, caused by a bacillus called Mycobacterium tuberculosis, is a deadly infectious disease that is transmitted through aerosol droplets, and is estimated to have infected one-quarter of the global population. It has a mortality rate of 50% if treatment is not provided; however, with timely detection and interventions, which include currently recommended anti-TB drugs, 85% of people can be cured. India, being a resource-poor country, has one of the highest burdens of TB in the world, with an incidence of 210/100,000 in 2021, according to the World Health Organization (WHO) Global TB report of 2022.
Autonomía de las migraciones: de la producción política de fronteras a las luchas migrantes
Authors: Castillo Ramírez Guillermo
Published: August 2023

Within a global context, the increase in migrations in different regions of the world during this century has led to an increase in academic production on migration. The aim of this article is to analyze the autonomy of migration from the approaches of two of its greatest exponents, Mezzadra and De Genova, who investigate migration’s political condition, addressing the relationships of mutual influence between migrants, borders, and the State. The contribution of this paper is to show how this theoretical approach focuses on two fundamental processes to understand migration. On the one hand, it refers to the actions, strategies, and practices of those involved in shaping cross-border migration. On the other hand, it considers the role of States and borders as legal-political and historical constructs in shaping international (often irregular) migratory flows.

Published: August 2023

Microwave-assisted enzymatic extraction (MAEE) was used for the separation of polysaccharides from micro-Chlorella. The extraction condition of MAEE was optimized by Box-Behnken design and response surface methodology. Results showed that the optimal condition for the extraction of Chlorella sp. crude polysaccharides (CSCP) was at 50°C for 2.3 h with 380 W of microwave power and 0.31% of enzyme dosage. Under the optimal extraction condition, the extraction yield of CSCP reached 0.72%. Similarly, the α-amylase modification conditions of the CSCP were also optimized, in which the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging rate was used as the response value. The scavenging rate of DPPH free radicals was 17.58% when enzyme dosage was 271 U/g at 51°C for 14 min. Moreover, the enzyme-modified CSCP presented a typical heteropolysaccharide mainly including glucose (48.84%), ribose (13.57%) and mannose (11.30%). MAEE used in this work achieved a high extraction yield of CSCP, which provides an efficient method for the extraction of CSCP from Chlorella sp.

Published: August 2023

Soybean (Glycine max) is an increasingly relevant crop due to its economic importance and also a model plant for the study of root symbiotic associations with nodule forming rhizobia. Plant polyesters mediate plant-microbe interactions with both pathogenic and beneficial microbes; suberin has been hypothesized to play a key role during the early steps of rhizobia attachment to the root. The downside is that suberin chemistry in soybean root is still scarcely studied. This study addresses this outstanding question by reporting a straightforward workflow for a speedy purification of suberin from soybean root and for its subsequent detailed chemical analysis. To purify suberin, cholinium hexanoate (an ionic liquid) was used as the catalyst. The ensuing suberin is highly esterified as observed by a precise Nuclear Magnetic Resonance quantification of each ester type, discriminating between primary and acylglycerol esters. Moreover, the composing hydrolysable monomers detected through GC-MS revealed that hexadecanoic acid is the most abundant monomer, similar to that reported before by others. Overall, this study highlights the adequacy of the ionic liquid catalyst for the isolation of suberin from soybean roots, where the polymer natural abundance is low, and builds new knowledge on the specificities of its chemistry; essential to better understand the biological roles of suberin in roots.

Published: August 2023

In the global context of climate change and carbon neutrality, this work proposes a strategy to improve the light absorption of photocatalytic water-splitting materials into the visible spectrum by anion doping. In this framework, reactive high power impulse magnetron sputtering (HiPIMS) of a pure Zr target in Ar/N2/O2 gas mixture was used for the deposition of crystalline zirconium oxynitride (ZrO2-xNx) thin films with variable nitrogen doping concentration and energy band-gap. The nitrogen content into these films was controlled by the discharge pulsing frequency, which controls the target surface poisoning and peak discharge current. The role of the nitrogen doping on the optical, structural, and photocatalytic properties of ZrO2-xNx films was investigated. UV-Vis-NIR spectroscopy was employed to investigate the optical properties and to assess the energy band-gap. Surface chemical analysis was performed using X-ray photoelectron spectroscopy, while structural analysis was carried out by X-ray diffraction. The increase in the pulse repetition frequency determined a build-up in the nitrogen content of the deposited ZrO2-xNx thin films from ∼10 to ∼25 at.%. This leads to a narrowing of the optical band-gap energy from 3.43 to 2.20 eV and endorses efficient absorption of visible light. Owing to its narrow bandgap, ZrO2-xNx thin films obtained by reactive HiPIMS can be used as visible light-driven photocatalyst. For the selected processing conditions (pulsing configuration and gas composition), it was found that reactive HiPIMS can suppress the hysteresis effect for a wide range of frequencies, leading to a stable deposition process with a smooth transition from compound to metal-sputtering mode.

Background

Strain analyses derived from cardiovascular magnetic resonance-feature tracking (CMR-FT) provide incremental prognostic benefit in patients sufferring from acute myocardial infarction (AMI). This study aims to evaluate and revalidate previously reported prognostic implications of comprehensive strain analyses in a large independent cohort of patients with ST-elevation myocardial infarction (STEMI).

Methods

Overall, 566 STEMI patients enrolled in the CONDITIONING-LIPSIA trial including pre- and/or postconditioning treatment in addition to conventional percutaneous coronary intervention underwent CMR imaging in median 3 days after primary percutaneous coronary intervention. CMR-based left atrial (LA) reservoir (Es), conduit (Ee), and boosterpump (Ea) strain analyses, as well as left ventricular (LV) global longitudinal strain (GLS), circumferential strain (GCS), and radial strain (GRS) analyses were carried out. Previously identified cutoff values were revalidated for risk stratification. Major adverse cardiac events (MACE) comprising death, reinfarction, and new congestive heart failure were assessed within 12 months after the occurrence of the index event.

Results

Both atrial and ventricular strain values were significantly reduced in patients with MACE (p < 0.01 for all). Predetermined LA and LV strain cutoffs enabled accurate risk assessment. All LA and LV strain values were associated with MACE on univariable regression modeling (p < 0.001 for all), with LA Es emerging as an independent predictor of MACE on multivariable regression modeling (HR 0.92, p = 0.033). Furthermore, LA Es provided an incremental prognostic value above LVEF (a c-index increase from 0.7 to 0.74, p = 0.03).

Conclusion

External validation of CMR-FT-derived LA and LV strain evaluations confirmed the prognostic value of cardiac deformation assessment in STEMI patients. In the present study, LA strain parameters especially enabled further risk stratification and prognostic assessment over and above clinically established risk parameters.

Clinical outcomes of serum potassium in patients with percutaneous coronary intervention: insights from a large single-center registry
Authors: Ke Bingbing , Shen Aidong , Qiu Hui , Li Weiping , Chen Hui , Li Hongwei
Published: August 2023

Background

Serum potassium homeostasis plays an important role in myocardial electrical stability, but the impact of altered serum potassium levels on the major adverse cardiovascular and cerebral events (MACCE) in patients with percutaneous coronary intervention (PCI) has not been evaluated.

Aim

To evaluate the association between serum potassium level and the risk of MACCE in PCI patients.

Materials and methods

This retrospective study involved 8,263 in-patients from a single-center registry who were successfully treated with PCI between January 2003 and December 2020. Clinical data were collected for 24 h after admission. Data were analyzed from June 2003 to December 2021. The primary outcome was MACCE, defined as a composite of all-cause death, myocardial infarction, revascularization, stroke, and heart failure-related hospitalization.

Results

The median [interquartile range (IQR)] follow-up for all patients was 4.0 (2.1, 5.8) years, and 1,632 patients (19.7%) were diagnosed with MACCE. High serum potassium levels were associated with a 20% increased risk of MACCE (hazard ratio [HR]: 1.20, 95% confidence interval [CI]: 1.05–1.38, P = 0.008) and 72% increased risk of all-cause death (HR: 1.72, 95% CI: 1.39–2.14, P < 0.001). Multivariate Cox analysis showed that the risk of MACCE was higher in patients at the highest quartile of serum potassium (Q4 vs. Q1: adjusted HR: 1.18, 95% CI: 1.02–1.35, P = 0.026). Moreover, a higher serum potassium level was always associated with a higher risk of all-cause death (Q4 vs. Q1: adjusted HR: 1.50, 95% CI: 1.17–1.91, P = 0.001). A U-shaped relationship between serum potassium levels, MACCE, and all-cause death was derived in patients undergoing PCI. Serum potassium levels, maintained within the range of 3.8–4.0 mmol/L before PCI, exhibited the lowest risk of associated MACCE and all-cause death.

Conclusion

Our results demonstrate that the serum potassium level could be associated with higher risks of MACCE and all-cause death in PCI patients. In particular, serum potassium levels maintained at 3.8–4.0 mmol/L before PCI could lower the risk of MACCE and all-cause death.
Early onset of heavy rainfall on the northern coast of Ecuador in the aftermath of El Niño 2015/2016

In January 2016, a high-precipitation event (HPE) affected northwestern Ecuador, leading to devastating flooding in the Esmeraldas River Basin. The HPE appeared in the aftermath of the 2015/16 El Niño as an early onset of heavy rainfalls, normally expected in the peak rainy season between March and April. We investigate the local HPE atmospheric setting and the regional “weather-within-climate” characteristics of the growing-season rainfall between December and January using gauge data, satellite imagery, and reanalysis. The unusual convective environment in late January 2016 involved local and synoptic drivers leading the development of a mesoscale convective complex (MCC) during the nighttime of 24th January. The genesis of the MCC was related to an early-arriving thermal weather state and orographic lifting; the Andean ranges acted as both a channel boosting upslope flow and convective updrafts and as a heavy rain divide for inner valleys. The synoptic controls were associated with 1) a southern boundary of the inter-tropical convergence zone, abnormally displaced to 4°N as response to the 2015/16 El Niño where eastward air surges merge upward vertical mass fluxes; 2) the arrival to the Ecuadorian coast of an equatorially propagating Kelvin wave; and 3) a low-mid level moisture influx coming from the Amazon associated with ascent due to changes in the Walker circulation. Lastly, we suggest that the convective environment in late January was also favored by cross-time-scale interference of the very strong El Niño event and a strong and persistent Madden-Julian oscillation (MJO) in the central Pacific.

This study’s significance lies in its recognition of the evolving educational landscape and the need for a new type of specialist who can adapt to modern innovations and effectively implement digital tools and platforms in distance learning. In the context of the ongoing education reform in Kazakhstan, the study focuses on improving the quality of higher professional education to meet international standards. Specifically, it emphasizes the importance of training future teachers who are prepared to teach foreign languages through distance learning using digital resources. The main aim of the study is to describe a structured approach to teacher training by proposing a methodical system for the formation of professional competences of a future foreign language teacher in the conditions of distance learning at a university. The components of this system, such as aim, content, methods, forms, tools, and outcome, provide a comprehensive framework for developing the following competences: digital, psychological-pedagogical, linguistic, foreign language communicative, and methodical competences. Additionally, the study introduces an elective course, “Organization and methods of distance learning of a foreign language,” which serves as a practical implementation of the proposed methodical system. This course, when integrated into the curriculum of a pedagogical university, aims to equip future teachers with the necessary knowledge and skills to successfully navigate the challenges and opportunities presented by distance learning.
Regulation of autophagy by natural polyphenols in the treatment of diabetic kidney disease: therapeutic potential and mechanism

Published: August 2023

Diabetic kidney disease (DKD) is a major microvascular complication of diabetes and a leading cause of end-stage renal disease worldwide. Autophagy plays an important role in maintaining cellular homeostasis in renal physiology. In DKD, the accumulation of advanced glycation end products induces decreased renal autophagy-related protein expression and transcription factor EB (TFEB) nuclear transfer, leading to impaired autophagy and lysosomal function and blockage of autophagic flux. This accelerates renal resident cell injury and apoptosis, mediates macrophage infiltration and phenotypic changes, ultimately leading to aggravated proteinuria and fibrosis in DKD. Natural polyphenols show promise in treating DKD by regulating autophagy and promoting nuclear transfer of TFEB and lysosomal repair. This review summarizes the characteristics of autophagy in DKD, and the potential application and mechanisms of some known natural polyphenols as autophagy regulators in DKD, with the goal of contributing to a deeper understanding of natural polyphenol mechanisms in the treatment of DKD and promoting the development of their applications. Finally, we point out the limitations of polyphenols in current DKD research and provide an outlook for their future research.

Breakfast is considered a healthy dietary habit which can track over time from childhood to adulthood. The breakfast meal has the potential to improve daily dietary quality, particularly if it includes a range of food groups and adequate nutrient intakes. However, research on breakfast consumption trends among young Australian children aged up to 5 years is currently limited. This study assessed children’s usual breakfast food group and nutrient intakes at ages 1.5 (n = 369), 3.5 (n = 242), and 5.0 (n =240) years using three 24-hour dietary recalls from the Melbourne InFANT program. Tracking of food groups at breakfast across the three ages was assessed by Pearson correlation of energy-adjusted food intake residuals. The main food groups consumed at breakfast were grains, milk/alternatives and discretionary items, with vegetables rarely consumed at any age. Our study found that while breakfast contributed about 20% of total daily energy, this provided 20%-29.1% of total daily intake across all ages for carbohydrates, total sugars, calcium and potassium. For the contribution to daily recommendations, breakfast contributed more than about a third of daily recommended intakes for some micronutrients (e.g., iron, calcium and zinc), and a large proportion (over 40%) of sodium intake. Children consumed 11.9% -15.2% of their energy at breakfast from saturated fat, which is higher than the recommended total energy contribution of saturated fat (no more than 10% from saturated fat). For tracking of most food groups and nutrients, tracking was found to be low or moderate over time. Given the contribution that breakfast can make to ensure children achieve their daily dietary intakes, early interventions for young Australian children should focus on practical strategies to increase vegetable intake while reducing sodium and saturated fat intake at breakfast.

The polypyrrole@ZrO2–ZnO (PPy@ZrO2–ZnO) electrodes were synthesized using an in situ chemical oxidative method. The samples were characterized by XRD, FTIR, XPS, UV-vis, TGA, and BET. In addition, the electrochemical characteristics of the electrodes are tested by cyclic voltammetry (CV), galvanostatic charge and discharge (G.C.D.), and electrochemical impedance spectroscopy (E.I.S.). The values of the specific capacitances and the energy densities of PPy@ZrO2–ZnO (1.0) and PPy@ZrO2–ZnO (0.5) at a current density of 0.5 A g−1 are recorded as (395.3 F g−1 and 508.5 Wh·kg−1) and (195.3 F g−1 and 351.5 Wh·kg−1), respectively. Furthermore, the electrode stability for the formed samples was also determined, which exhibited specific capacitance retention at 90.2% for PPy@ZrO2–ZnO (1.0) and 82.4% for PPy@ZrO2–ZnO (0.5) after cycling up to 4,000 cycles. This work provides an efficient approach to the potential of the synthesized samples for application as electrodes in a supercapacitor.
