Published: January 2023

The character crisis makes Indonesian education urgently need improvement through the educational transformation that not only prioritizes cognitive but also develops the student's skills and character. This study aims to determine the relationship and contribution of counseling guidance services in pesantren to children's character education through service management analysis. The researcher used qualitative research methods with triangulation for data collection. The evaluation instrument involves the Stufflebeam evaluation components. They are context, input, process, and product. The results indicate that the planning and controlling management functions have not been able to function properly and have caused problems in the provided services. The service types have led to increased competence, improved attitudes, and students’ character. However, there were many obstacles in the process. They are funding, infrastructure, implementation time, control from the leadership and administration as well as regular reporting of activities. These conditions have an impact on the role and effectiveness of counseling guidance in assisting santri to maximize their potential and achieve their developmental tasks.

The Role of Profitability in Moderating Political Connections, Corporate Risk, Leverage, And Firm Size to Tax Avoidance
Authors: Lala Latifatul Lala , Kristiana Ida , Hanum Ayu Noviani
Published: January 2023

This study examines the effect of political connection, corporate risk, leverage, and firm size on tax avoidance with profitability as a moderating variable. The data used are annual financial reports of food and beverage registered in the Indonesia Stock Exchange (IDX) for the 2018-2021. The sample used was 99 companies, obtained using a purposive sampling technique. The data analysis used is Multiple Linear Regression and Moderated Regression Analisis (MRA). In this study, there is a novelty, namely the addition of profitability as a moderating variable, because, in previous studies, the use of moderation with the same independent and dependent variables was not found in this study. The result of this study shows that political connection, corporate risk, and firm size do not affect tax avoidance. Meanwhile, leverage has a significant positive effect on tax avoidance. In addition, profitability can moderate the effect of firm size on tax avoidance. However, profitability cannot moderate the effect of political connection, corporate risk, and leverage on tax avoidance. Based on these results, the implication of this study is that leverage in companies must be considered because the greater the level of corporate leverage, the lower the tax burden borne by the company so that debt becomes a management priority to avoid a larger tax burden. Therefore, the greater the leverage ratio, the greater the level of corporate tax avoidance. Likewise, profitability can moderate the effect of company size on tax avoidance must also be considered because the larger the size will enable the company to earn high profits. The firm value will also increase, so the company can control tax avoidance.

Piama Gaidenko and the Philosophers of the Sixties
Authors:   RAS Institute of Philosophy, Solov’ev Erikh Yu.
Published: January 2023

This article is an essay on the life and work of Piama P. Gaidenko. I argue that Gaidenko belonged to the informal community of philosophers of the Sixties who sought to bring about a radical renewal of Soviet philosophy. However, unlike most of them, ever since her post-graduate years she had been a religious philosopher. Her works The Tragedy of Aestheticism, The Evolution of the Concept of Science and Breakthrough to the Transcendent are the most expressive evidence of this. They defend a moral philosophy based on faith and opposed to the Hegelian apology of speculative reason. Gaidenko insists that philosophically meaningful faith is compatible with scientific rationality. A strictly rational account of the philosopher’s mission and of the relationship of philosophy with art, religion, and science, she argues, ought to be an indispensable component of a moral philosophy based on faith. In the paper I pay special attention (as did Gaidenko herself) to the problem of making the philosophical heritage relevant and the concept of existential philosophy in Gaidenko’s work. The essay is supplemented by a review of Gaydenko’s re-published, little-known article “Apocalypticism, Chiliasm and Hellenic Philosophy” (2000). In it I focus mainly on the relation between philosophy and Christianity and the transformation of Utopianism in an era of deepening secularization.

The Role of Kant’s Anthropology in Ralf Dahrendorf’s Theory of Conflicts: “Unsocial Sociability” in Human Nature, Culture and Politics
Authors:   RAS Institute of Philosophy, Zhavoronkov Alexey G.
Published: January 2023

My paper focuses on one of the most discussed key concepts of Kant’s social philosophy, namely on his notion of “unsocial sociability”, from the perspective of its influence on Ralph Dahrendorf’s theory of social conflicts. In the first part, I show how various areas of Kant’s philosophy – his ethics, philosophy of history, anthropology, social and political philosophy – are connected through this concept, and briefly describe the key features of its critical reception. In the second half of the article, I turn to the question concerning the role of this concept in Dahrendorf’s theory. I show that this concept was already implicitly present in his early studies of the 1950s and was gradually becoming a more explicit part of his approach to the analysis of conflicts, playing its most prominent role in his works of the 1980s and 2000s. In contrast to those critics of Dahrendorf who regard the notion of unsocial sociability as methodologically alien to his social theory, I argue that Kant’s concept is used as its theoretically substantiated component rather than an anthropological vignette that only pays tribute to Kant as a social thinker. Moreover, it still significantly influences more recent approaches, primarily because it allows scholars to see conflicts in a normative light and to critically assess utopian elements of previous interpretations.

Published: January 2023

L-Amino acid oxidase has significant values in different biotechnology sectors. In this study, Aspergillus terreus MZ769058 had been reported as new fungal isolate for production of this enzyme. It was partially purified using ammonium sulfate precipitation methodology with87.9 U/mg protein maximal specific activity and1.69 folds purification fold for 30–60% saturation. Ion-exchange chromatography was further applied for achieving high value of purification fold (2.55) and high specific activity as 132.5 U/mg.This purified enzyme showed homodimer nature with molecular weight of subunit as 90 kDa and 180 kDa by SDS electrophoresis and NATIVE PAGE respectively. The activity of enzyme was found as maximum 193.5 U/l at optimum value of pH 6.0.The enzyme was active throughout a wide range of temperatures and showed maximum activity (227.08U/l) at optimum temperature 30°C. The value of Michaelis parameters of Km and Vmaxwas estimated as 26 mM and 250 µmole/min/mg proteinsrespectively. The catalytic efficiency of this enzyme (Kcat) value was determined as 2.5 µmole/min/mg. Metal ions such as FeSO4 (85.4 %), Na2MO4 (81.2 %), and CuSO4 had showed negative effect on the activity of LAAO enzyme. Metal ions like MgSO4, H3BO3, and ZnSO4had showed very little effect on activityof L-Amino acid oxidase. The activity of LAAO enzyme was strongly inhibited at a concentration of 10 mM CaCl2.This enzyme was strongly inhibited with α-napthol (34.4%), EDTA (34.2%), Glycine (39%) sodium azide (41.4%), and riboflavin (85.3%). Fourier transform infrared spectroscopyhad confirmed the presence of the amine and aldehyde groups with C-H stretch, C=O stretch, C-O stretch at peak of 2927.95, 1745.25, and 1078.64 cm-1.

Published: January 2023

Overexpression of Bcl-2 proteins such as Bcl2L10, also referred to as Nrh, is associated with resistance to therapy and poor survival in various cancers, including breast cancer, lung cancer and leukemia. The single nucleotide polymorphism (SNP) of BCL2L10 in its BH4 domain at position 11 (BCL2L10 Leu11Arg, rs2231292), corresponding to position 11 in the Nrh open reading frame, is reported to lower resistance towards chemotherapy, with patients showing better survival in the context of acute leukemia and colorectal cancer. Using cellular models and clinical data, we aimed to extend this knowledge to breast cancer. We report that the homozygous status of the Nrh Leu11Arg isoform (Nrh-R) is found in 9.7–11% percent of the clinical datasets studied. Furthermore, Nrh-R confers higher sensitivity towards Thapsigargin-induced cell death compared to the NrhL isoform, due to altered interactions with IP3R1 Ca2+ channels in the former case. Collectively, our data show that cells expressing the NrhR isoform are more prone to death triggered by Ca2+ stress inducers, compared to Nrh-L expressing cells. Analysis of breast cancer cohorts revealed that patients genotyped as Nrh-R/Nrh-R may have a better outcome. Overall, this study supports the notion that the rs2231292 Nrh SNP could be used as a predictive tool regarding chemoresistance, improving therapeutic decision-making processes. Moreover, it sheds new light on the contribution of the BH4 domain to the anti-apoptotic function of Nrh and identifies the IP3R1/Nrh complex as a potential therapeutic target in the context of breast cancer.

Published: January 2023

Excessive noise levels in the urban environment is a challenging issue in the sustainable urban development. Determine the noise level and noise affected areas for formation of proper plan is the significant theme of contemporary urban research work. Jamshedpur is the rapid growing industrial urban area in Jharkhand state of India. At present, this city has started to face a severe noise pollution due to rapid industrial growth, high population growth, commercial activity, and increase in transport mode along with legal and illegal construction. Therefore, the present study has been carried out to assess the urban environmental noise pollution in the study area. Several noise indicators like L10,L50,L90, Equivalent continuous noise level (Leq), Noise pollution level (Lnp), Noise Climate (NC), Traffic Noise Index (TNI), Noise Exceeding Factor (NEF), Day-night noise level () have been computed and GIS techniques also considered to determine the scenario of noise level along with their Spatio-temporal variation in the study area. Correlation and regression have been used to assess the relationship between noise levels, traffic volume, and traffic speed. The result indicates that 35 data sampling sites out of 47 sites have affected serious noise pollution and this pollution is partially affected by the volume of traffic flow. The living inhabitants of this area face noise pollution-related issues. To solve the serious noise pollution related problem in Jamshedpur Urban Agglomeration (JUA) present endeavour are very necessary to formulate some strategies and regulations as well as their implementation.
Elevated CO2 alters nitrogen cycle in global croplands

Published: January 2023

Croplands support global food security and human nutrition, representing the largest nitrogen flows globally. Elevated atmospheric carbon dioxide (CO2) level is a key driver of climate change with multiple impacts on food security, environmental and human health. However, our understanding of how the cropland nitrogen cycle will respond to elevated CO2, so far is not well developed. We demonstrate that elevated CO2 alone would induce a synergistic intensification of the nitrogen and carbon cycles, promote nitrogen use efficiency by 19% (14-26%) and biological nitrogen fixation by 55% (28-85%) in global croplands. This would lead to increased crop nitrogen harvest (+12 Tg), substantially lower fertilizer input requirements (-34 Tg) and an overall decline in reactive nitrogen loss (-46 Tg) annually under future elevated CO2 scenarios by 2050. The impact of elevated atmospheric CO2 on altered cropland nitrogen cycle would amount to 672 billion US dollars benefit in terms of avoiding damages to human and ecosystem health. Regionally, the largest alteration would materialize in China, India, North America, and Europe. To improve the policy design for food security and sustainable development, it would be paramount to integrate the effect of rising CO2 on nitrogen cycle into state-of-the-art Earth System Models.
The impact of perceived social support and coping on distress in a sample of Atlantic Canadian HP Students during COVID-19 compared to pre-COVID peers
Authors: Pamela Button , Laura Fallon , Ken Fowler
Published: January 2023

Students pursuing higher education and health professional (HP) programs (e.g., nursing, pharmacy, social work, medicine) experience stressors including academic pressures, workload, developing professional competencies, professional socialization, the hidden curriculum, entering clinical practice and navigating relationships with colleagues. Such stress can have detrimental effects on HP students physical and psychological functioning and can adversely affect patient care. This study examined the role of perceived social support, coping, and resilience in predicting distress of Atlantic Canadian HP students during the COVID-19 pandemic and compared the findings to a pre-COVID population of age and sex matched Canadians. Second year HP students (N = 93) completed a survey assessing distress, perceived social support, and resilience and open-ended questions on student awareness of supports and counselling available to them, their use/barriers to the services, and the impact of COVID-19 on their personal functioning. HP student responses were also compared with age and sex matched Canadian peers from data collected prior to COVID-19. It was found that HP students reported moderate to severe psychological distress, and while they reported high levels of social support on a measure of perceived social support they also reported that the COVID-19 pandemic made them feel isolated and that they lacked social support. It was found that the sample of HP students reported significantly higher psychological distress than the mean scores of the age and sex matched sample of Canadian peers. These findings call for creation of more tailored interventions and supports for HP students.
Estimating chromosome sizes from karyotype images enables validation of de novo genome assemblies
Authors: Pippel Martin , Ludwig Arne , Dibrov Alexandr , Myers Eugene
Published: January 2023

Owing to decreased costs over time, the genomes of an increasing number of species are being sequenced. However, chromosome-scale genome assembly is affected by scaffolding errors, resulting in incorrect chromosome sizes. Here, we present KICS, a semi-automated and cost-efficient approach for examining the validity of the assembly by estimating relative chromosome sizes from karyotype images. The method employs threshold-based image segmentation and uses the extracted chromosome areas as proxies for the actual chromosome sizes. A strong correlation between chromosomal area and DNA confirmed the suitability of our approach, as assessed from karyotype images of multiple species. KICS can be applied to microchromosomes, and we identified assembly errors made by HiC sequencing in the horseshoe bat genome. By using the human genome as a reference, for which telomere-to-telomere data are available, we estimate an error of our tool of ∼6Mb. We foresee that KICS will be routinely used as an inexpensive and intuitive tool to validate the de novo assembly of new genomes.

Published: January 2023

This retrospective study evaluated the characteristics and response of subretinal hyperreflective material (SHRM) to anti-vascular endothelial growth factor (VEGF) treatment in eyes with myopic choroidal neovascularization (CNV).
The visual acuity (VA) was assessed at 3, 6, and 12 months after initiating anti-VEGF treatment in 116 patients (119 eyes) with SHRM and myopic CNV. Multimodal imaging, including color fundus photography, fluorescein angiography (FA), and optical coherence tomography angiography (OCT-A), were performed. We compared type 2 neovascularization (NV) (n=64), subretinal hyperreflective exudation (SHE) (n=37), NV with hemorrhage (n=15), and fibrosis (n=3).
The type 2 NV and NV with hemorrhage groups showed significant VA improvement after 12 months of treatment; the SHE group failed to show improvement (p<0.05, p<0.05, and p=0.366, respectively). All groups showed a significant reduction in central foveal thickness after 12 months of treatment (all p<0.05). The SHE group had a significantly higher incidence of interrupted ellipsoid zone than the other groups (p<0.05).
Myopic CNV can present as SHRM on OCT-A. Visual prognoses vary in different SHRM types. OCT-A and FA may help predict the outcomes of different subtypes of myopic CNV. SHE is predictive of outer retinal layer atrophy in patients with various SHRM types.
Prevalence of long acting reversible contraceptives utilization and associated factors among Ethiopian women: A systematic review and meta-analysis
Authors: Lemma Dereje , Abdissa Bayisa , Kolola Tufa
Published: January 2023

Background Contraception has become an essential, safe and cost effective component in the lives of women of reproductive age since it avoids the depletion of maternal nutritional reserves and lowers the risk of anaemia caused by many pregnancies and deliveries. Objective The aim of the study was to determine the pooled prevalence of long acting reversible contraceptive utilization and associated factors among Ethiopian women. Methods Systematic review and meta-analysis was conducted using PRISMA flow diagram to initially identify (n = 435 databases) and (n = 5 registers). We searched different databases (Pub Med, Scopus, Science Direct, Web of Science, and Google Scholar) to access published articles between 2017 to March 2022. Heterogeneity between studies was measured using 12 indexes and subgroup analysis was done to determine the possible causes of heterogeneity. Results A total of 440 studies identified and 75 were included in a full review. Only 27 studies met the inclusion criteria. Long-acting reversible contraceptives users were identified in 3,588 of the 12,741 women studied, making a 29% overall prevalence (95% CI: 26–32). With considerable heterogeneity (X2 = 505.29, P = 0.001, I2 = 94.85%), the estimated prevalence differed significantly between studies. The odds of using Long acting reversible contraceptive was four times higher among those who have had previous history of LARC utilization (P = 0.001, 95% CI 2.55, 4.57), women with a positive attitude towards birth control (P = 0.001, 95% CI 1.5–2.3), and having good knowledge (p = 0.001, 95% CI 1.16–1.98) were two times more likely to use LARC compared to their counter parts Conclusion Prevalence of Long acting reversible contraceptive was low among Ethiopian women 29% (95%CI (26–32 ). Previous Long acting reversible contraceptive use, positive attitude towards birth control, and having good knowledge were independent predictors of LARC utilization.

Authors: Gibreal Omar , Al-modallal Yasser , Mahmood Ghiath , Gibreal Ahmad
Published: January 2023

Background
No randomized controlled trial (RCT) has studied the accuracy of surgical guides used in terms of orthodontic treatment acceleration. Therefore the aim of this trial was to assess computer-guided piezocision-based orthodontic.
Materials and Methods
Thirty-two patients with severely crowded upper anterior teeth were enrolled and randomly allocated to either the experimental group (ExpG) or the control one. Subjects of the ExpG received three-dimensional (3D) guided piezoelectric corticotomies on the buccal alveolar bone of the anterior region. Five piezocision cuts were properly performed between each anterior teeth and the adjacent in virtual models. Surgical guides were designed and 3D-printed with preplanned slots that guide gingival and then piezoelectric incisions. The patients underwent Cone-Beam Computed Tomography CBCT before and immediately after surgery. Thus, Predesigned piezocisions were compared to the actual ones in attempt to measure three dimensional deviations of the applied peizocisions.
Results
Ninety-six severe maxillary dental crowding were assigned for eligibility, 40 of them met the inclusion criteria. Thirty-two participants were randomly allocated to the trial`s groups. No patient was lost to follow-up neither from the control nor the experimental group. Overall alignment time (OAT) was reduced by 53% in the experimental group compared to the control group. The mean of the 3D deviation of the surgical guide was 0.23mm (standard deviation 0.19mm).
Conclusion
The values of the surgical guide deviation was nearly null, which confirms that this innovative technique is clinically applicable. Furthermore, this technique was impressively effective in accelerating orthodontic tooth movement.

Multi-criterion approach for assessment of hydrochemical characteristics and human health risk of groundwater in Khartoum State, Sudan
Authors: Mohammed Musaab A. A. , Eltijani Abdelrhim , Szabó Norbert P. , Szűcs Péter
Published: January 2023

Recently, groundwater has been recognized as one of the primary sources of water supply in Sudan. However, groundwater quality continues to deteriorate due to natural and human-induced activities. This research employed groundwater quality index (GWQI), multivariate statistical methods and human health risk assessment to investigate the suitability of groundwater for domestic uses in northern Khartoum state, Sudan. The groundwater samples were analyzed for eleven physiochemical parameters, including pH, EC, TDS, TH, Cl-, SO4-2, NO3-, Ca+2, Mg+2, Na+, HCO3- and the primary investigation indicated the deviation of these parameters from World Health Organization (WHO) standards. The hydrochemical analysis revealed different groundwater facies with the dominance of Ca-Mg-HCO3 water type. Consequently, the groundwater samples were classified, based on GWQI, into three categories as 76.4 % of the samples fall in the excellent water class, 17.6 % are projected in the good water class, and 5.9 % of groundwater samples are considered unsuitable for human consumption. The multivariate statistical methods, including Pearson's correlation analysis, hierarchical cluster analysis (HCA), and principal component analyses (PCA), were applied to determine groundwater quality data's structure and the primary factors influencing groundwater quality. These techniques revealed that groundwater in the study area is mainly controlled by rock-water interaction and agricultural practice. Additionally, they were used to categorize groundwater samples based on their chemical content. As a result, three types of groundwater were identified low, medium, and highly mineralized. In the final stage, the non-carcinogenic human health risk was assessed based on the concentration of NO3- and the obtained hazard quotient for children indicated that 64.7 % of groundwater samples are beyond the permissible limit (1<) and the use of these samples may result in health consequences. As a result, remedial measures are suggested for the sustainable use of groundwater.
Determinants and Spatial Factors of Anemia in Women of Reproductive Age in the DRC: A Bayesian Multilevel Ordinal Logistic Regression Model Approach
Authors: Soda Martin Abysina , Kandala Ngianga-Bakwin , Hamuli Eugénie Kabali , Batina Salomon
Published: January 2023

Background: As a global public health problem, anemia affects more than 400 million women of reproductive age worldwide, mostly in Africa and India. In the DRC, the prevalence of this anemia has decreased slightly from 52.9% in 2007, to 46.4% in 2012 and 42.4% in 2019. However, there is considerable regional variation in its distribution.
Methods: Based on the Bayesian Multilevel Spatial Ordinal Logistic Regression Model, we use the DHS-DRC II data to observe whether individual and environmental characteristics of the reproductive-age woman contribute to the development of anemia and the mapping of anemia in terms of residual spatial effects.
Results: Age, pregnancy status, body mass index, education level, current breastfeeding, current marital status, contraceptive and insecticide-treated net use, source of drinking water supply, toilet/latrine use, and province of residence were the factors contributing to anemia in women of reproductive age in DRC. With Global Moran's I = -0.00279, p-value ≥ 0.05, the spatial distribution of anemia in women of reproductive age in DRC results from random spatial processes. Thus, the observed spatial pattern is completely random.

Purpose: Neutropenia is a common adverse event during myelosuppressive oncological chemotherapy, predisposing to febrile neutropenia (FN). Patients with coexisting moderate-to-severe chronic kidney disease (CKD) have an increased risk of FN, included in the guidelines for the primary prophylaxis of FN. However, this does not include mild kidney function impairment with estimated glomerular filtration rate (eGFR) 60–89 ml/min/1.73m2. This prospective study analyzed the risk of neutropenia in patients on chemotherapy without indication for the primary prophylaxis of FN.
Methods: The study enrolled 38 patients starting chemotherapy, including 26 (68.4%) patients aged 65 years or more. The median duration of follow-up was 76 days. The methodology of creatinine assessment enabled the use of the newly recommended CKD-EPI formula for identifying patients with a mild reduction of glomerular filtration.
Results: Sixteen (42.1%) patients developed at least G2 neutropenia without episodes of FN. Only five (13.1%) patients had eGFR <60 ml/min/1.73m2, while 15 (62.5%) eGFR < 90ml/min/1.73m2. The relative risk of neutropenia in patients with impaired eGFR was over six times higher than in patients with eGFR >90 ml/min/1.73m2 (RR=6.08; 95%CI:1.45–27.29; p< 0.01).
Conclusions: Our observation indicates that even a mild reduction in eGFR is a risk factor for the development of neutropenia and a potential risk factor for FN.

In an era dominated by electronic equipment, the development of high-efficiency electromagnetic wave (EMW) absorbers is of great significance in solving electromagnetic (EM) pollution. Micro/Nanostructural engineering for optimizing EMW absorption performance depends on the design of vacancy, defect, and heterogeneous interface, which remains a considerable challenge in adjusting the micro and macro-interface effects. In this work, S atoms are incorporated into a dielectric-magnetic complementary system (Fe3O4/Fe7S8@C) to arouse the polarization effect of vacancies, defects, and non-uniform interfaces, thus tremendously boosting the EM energy attenuation capacity. Besides, the carbon shell provides more propagation paths for the dissipation of EMWs, and dielectric-magnetic synergy improves impedance matching. Eventually, in comparison with Fe2O3 and Fe3O4@C composites, interface-engineered Fe3O4/ Fe7S8@C acquires a much better EM wave absorption performance. Its minimum reflection loss value reaches as much as -56.2 dB with a thickness of only 1.6 mm, and the corresponding effective absorption bandwidth (EAB) is up to 4.5 GHz. This unique hydrangea-like layered structure provides space to facilitate non-uniform coupling between the layers and has strong anisotropy to enhance the magnetic response. The high density of magnetic flux in the nanosheets builds a three-dimensional magnetic coupling network, which is supported by Off-axis electron holography. Besides, the radar cross section from HFSS simulation further confirms that S-doping can favor the best synergy between dielectric and magnetic losses, facilitating the composite to achieve a more optimal impedance matching and improve the absorption capacity. In conclusion, this work presents new ideas for the design of excellent absorbing materials.

Published: January 2023

Provisioning services for Internet of Things (IoT) devices leads to severalchallenges: heterogeneity of IoT devices, varying Quality of Services (QoS)requirements, and increasing availability of both Cloud and Fog resources. Thelast of these is most significant to cope with the limitations of Cloud infrastructureproviders (CIPs) for latency-sensitive services. Many Fog infrastructure providers(FIPs) have recently emerged and their number is increasing continually. FLEX isproposed in this work as a platform for selecting a location for service placementin a multi-Fog and multi-Cloud environment. For each service, FLEX broadcastsservice requirements to the resource managers (RMs) of the available Fog andCloud service providers and then selects the most suitable provider for that service.FLEX is scalable and flexible as it leaves it up to the RMs to have their ownpolicy for the placement of submitted services. Service placement and resource selectionhas been formulated as an optimization problem and an efficient heuristicalgorithm is proposed to solve it. Results show that the proposed algorithm canbe used across both Cloud and Fog-based providers.

Purpose
To investigate the clinical outcomes of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles using frozen-thawed blastocyst transfers derived from zygotes with no (0PN) or one pronucleus (1PN).
Methods
This retrospective study included 7084 0PN, 2238 1PN and 72266 two-pronuclear (2PN) embryos cultured into blastocyst stage from 19631 IVF and 12377 ICSI cycles between March 2018 and December 2021. Developmental potential and clinical outcomes of 0PN, 1PN and 2PN embryos were analyzed. A total of 290 0PN-derived, 92 1PN-derived and 1906 2PN-derived single frozen-thawed blastocyst transfers were performed. Chromosome analysis of 0PN-, 1PN- or 2PN-derived blastocysts used Infinium Asian Screening Array gene chip or next-generation sequencing.
Results
The available blastocyst rates of 0PN and 1PN embryos were significantly lower than those of 2PN embryos in both IVF and ICSI cycles. Single 0PN and 1PN blastocysts transferred in frozen-thawed cycles resulted in a similar clinical pregnancy rate, live birth rate and miscarriage rate compared with 2PN blastocysts, in both IVF and ICSI cycles. Genetic analysis showed that euploid rates of 0PN- and 1PN-derived blastocysts used for ICSI cycles were similar to that of 2PN-derived blastocysts.
Conclusion
Our study indicated that 0PN- and 1PN-derived blastocysts resulted in a similar CPR and LBR as 2PN-derived blastocysts. The 0PN- and 1PN-derived blastocysts from ICSI cycles can be transferred as well as those from IVF cycles when the number of 2PN-derived blastocysts is insufficient.

We characterize the daytime sky quality in terms of its brightness, cloud coverage and main weather variables at the Carlos Ulrico Cesco stationof the Felix Aguilar Astronomical Observatory (OAFA), located in El Leoncito national park, San Juan, Argentina. We have collected more than 15 years of daily observations from the auxiliary sky brightness detectors of the Mirror Coronagraph for Argentina (MICA, in operations from 1997 to 2012), including daily observing reports. We additionally present data from two meteorological stations that operated at the site from 2000 to 2020. We determine the main statistical properties and seasonal variability of daytime sky brightness, clear sky timefraction (CSTF), precipitable water vapor (WV), temperature, humidity and wind speed, which are relevant for solar and particularly coronal observations. Our results confirm that El Leoncito is an excellent place to perform daytimeastronomical observations. We measure a median sky brightness of 15.8 ppm, estimated at 526.0 ± 1 nm and 6 solar radii from the solar disk center; a median CSTF of 0.7; and a median WV below 6 mm. These values, and those of other relevant weather variables, are comparable to the levels found among the best astronomical observing sites in the world. Due to the extended period of time analyzed and high sampling frequency, the novel data and results presented in this report contribute to the analysis and interpretation of historical sky brightness data, and are of great value for the future planning of daytime astronomical instrumentation at El Leoncito.

Landslides continue to occur in the Elgon region despite interventions such as tree planting initiatives aimed at restraining them. The current study assessed the mechanical properties of six selected agroforestry tree roots on slope stability with a keen focus on root tensile strength, soil shear strength, and index of root binding. A standard deviation ellipse method was applied to model the spatial distribution patterns of selected agroforestry trees. Tree-landslide relationship was tested using the Pearson correlation method while root tensile and soil shear strength with a one-way (ANOVA) and descriptive statistics respectively. Species distribution results indicate a high dispersion rate of Croton macrostachyus and Markhamia luteaacross the study area and high concentration of Albizia coriaria downstream. A weak negative correlation (r = -0.20 < 0.01) was reported between diameter at breast height and landslide size. Tensile strength results observed a significant difference among species with (F (5, 573) = [18.161], p < 0.001) and Grevillea robusta (3.02±1.217kg/mm²), Albizia coriaria (2.53±1.382kg/mm²), and Markhamia lutea (2.28±1.01kg/mm²) as the best performers. The best shearing species was Albizia coriaria with average shear strength (52.46±10.24) kpa followed by Markhamia lutea (50.70±15.47) kpa. The Eucalyptus spp. on the other hand underperformed with average shear strength of (46.75±12.92) kpa. In conclusion, the presence of trees reduces landslide risk in an area and DBH is a very important guiding factor. Grevillea robusta, Albizia coriaria, andMarkhamia lutea emerged as best performers in terms of root tensile strength and soil shear strength hence their suitability for enhancing slope stability. However, Eucalyptus Spp., which is widely favoured in the region for its rapid growth was the worst performer with very low shear strength. Therefore, careful consideration of the tree characteristics is essential during promotion campaigns for slope stability in fragile environments.
