Published: October 2024

Abstract

The I-V curve tracer is a diagnostic instrument for assessing the I-V characteristics of PV strings. It is extensively utilized to gauge power generation efficiency and detect potential issues within PV strings. To enhance the precision and accuracy of data collection, various I-V tracer techniques have been devised. This article presents an innovative and cost-effective Online I-V Tracer Tool (OIVTT) designed specifically for high-power PV strings, The system operates online, allowing I-V tracing without taking the plant offline, while meeting the load's power requirements during the process. The proposed system utilizes an IGBT as a variable load, incorporates wireless data acquisition and Kodular-based mobile App communication module. The embedded control algorithm ensures equal spacing of data points throughout the I-V curve, maintaining a relative standard deviation (RSD) of less than 10%. Comparative analysis between the experimental curve and the standard mathematical model demonstrates the OIVTT’s ability to track real-time performance variations, with an overall deviation below 2%. These results emphasize the OIVTT’s reliability, accuracy, and its potential as a cost-effective alternative to commercial I-V tracers for diagnostics and maintenance in PV systems.

Abstract

Introduction
Data on outcomes of extracorporeal membrane oxygenation (ECMO) are limited in patients with pulmonary atresia intact ventricular septum (PAIVS). The objective of this study was to describe the use of ECMO and the associated outcomes in patients with PAIVS.
Methods
We retrospectively reviewed neonates with PAIVS who received ECMO between 2009–2019 in 19 US hospitals affiliated with the Collaborative Research for the Pediatric Cardiac Intensive Care Society (CoRe-PCICS). Patients who received ECMO were compared to those who did not and patients on ECMO who died were compared to those who survived by bivariate analysis and multivariable logistic regression. The predictive ability of a risk score for inpatient mortality (using beta-coefficients) was assessed by receiver operator curve analysis.
Results
Of 295 identified patients, 32 (11%) were supported with extracorporeal membrane oxygenation. Of these, 15 (46%) experienced mortality. A higher left pulmonary artery z-score (beta coefficient 0.72) and the presence of ventriculocoronary connections by cardiac catheterization (beta coefficient 1.25) was associated with an increased risk of ECMO (p-value < 0.01). The resulting risk score had an area under the curve of 0.71 (p-value 0.03) for prediction of need for ECMO.
Conclusion
In a multicenter cohort of patients with PAIVS, 11% received ECMO. Of those supported with ECMO, 46% experienced inpatient mortality. A higher left pulmonary artery z-score and the presence of ventriculocoronary connections appear to be risk factors for use of ECMO.

Abstract

A polyhouse experiment (2 year) was conducted at AICRP for Dryland Agriculture during 2021/22 and 2022/23, to evaluate the impact of sensor driven irrigation levels on yield, yield attributes, irrigation efficiency and economic returns of broccoli, capsicum, pole bean and cherry tomato. The experiments were laid out separately in RCBD with six replications for each crop and wireless soil moisture sensors were installed with the purpose for collecting real time soil moisture content and controlling the irrigation levels (75, 50 and 25% ASM) via smart phone and surface irrigation as control. The two years study found that, sensor irrigation scheduling at 75% ASM recorded significantly higher average yield of broccoli (26.05 t ha− 1), capsicum (48.59 t ha− 1), pole bean (37.08 t ha− 1) and cherry tomato (42.02 t ha− 1). The mean irrigation production efficiency of broccoli (84.98 kg/ha-mm), capsicum (102.25 kg/ha-mm), pole bean (114.27 kg/ha-mm) and cherry tomato (88.41 kg/ha-mm) was higher at 75% ASM. Regression analysis revealed the polynomial relationship between the average quantity of water applied and yield of broccoli, capsicum, pole bean and cherry tomato. This relationship, with R2 values ranging from 0.73 to 0.83, can be effectively utilized to optimize irrigation water distribution among the crops both individually and collectively. Scheduling of irrigation at 75% ASM, resulted substantially higher net returns of Rs. 6,55,899 ha− 1 for broccoli, Rs. 9,69,689 ha− 1 for capsicum, Rs. 11,07,535 ha− 1 for pole bean and Rs. 5,79,865 ha− 1 for cherry tomato.
Dominant contribution of Asgard archaea to eukaryogenesis

Abstract

The origin of eukaryotes is one of the key problems in evolutionary biology 1,2. The demonstration that the Last Eukaryotic Common Ancestor (LECA) already contained the mitochondrion, an endosymbiotic organelle derived from an alphaproteobacterium 3, and the discovery of Asgard archaea, the closest archaeal relatives of eukaryotes 4-8, inform and constrain evolutionary scenarios of eukaryogenesis 9. We undertook a comprehensive analysis of the origins of the core eukaryotic genes tracing to the LECA within a rigorous statistical framework centered around evolutionary hypotheses testing using constrained phylogenetic trees. The results reveal dominant contributions of Asgard archaea to the origin of most of the conserved eukaryotic functional systems and pathways. A limited contribution from Alphaproteobacteria was identified, primarily relating to the energy transformation systems and Fe-S cluster biogenesis, whereas ancestry from other bacterial phyla was scattered across the eukaryotic functional landscape, with almost no consistent trends. These findings suggest a model of eukaryogenesis in which key features of eukaryotic cell organization evolved in the Asgard ancestor, followed by the capture of the Alphaproteobacterial endosymbiont, and augmented by numerous but sporadic horizontal acquisition of genes from other bacteria both before and after endosymbiosis.

A Study on the Allelopathic Effects of Wild Barley (Hordeum spontaneum) Residue Incorporated with Soil on Growth of Some Plant species
Authors: Didar J. Tawfeeq  , Ali Kawa A. 
Published: October 2024

This study examines the allelopathic effects of wild barley (Hordeum spontaneum) on the growth and yield of bread wheat (Triticum aestivum), barley (Hordeum vulgare), and wild barley (Hordeum spontaneum). The experiment was conducted in a greenhouse at Shamamar-Hawler/ Kurdistan Region of Iraq using a complete randomized factorial design (CRD) within 3 replications. The roots, shoots, and seeds of wild barley were dried, powdered, and added to the soil at different concentrations (0%, 10%, 20%, 30%, and 40%) in 500 g pots. Each pot was planted with 5 seeds, which were later reduced to 3 seedlings. Growth parameters such as shoot and root lengths, dry weights, number of tillers, weight of spikes, seeds number per plant, and biological yield was measured. The results indicated significant effects of wild barley residues on the studied crops. Wheat showed the highest roots, shoots and total lengths were (29.56 cm, 17.05 cm and 46.58 cm, respectively) and the highest shoots and roots dry weights were (0.24 g and 0.30 g). Barley showed the highest number of stems (1.96) but the lowest shoots and dry weights of roots were (0.11 g and 0.23 g). Wild barley had the highest biological weight and harvest index (HI). Among the plant parts, seed extracts significantly enhanced growth parameters, while roots and shoots extract had the greatest inhibitory effects as wild barley residue concentrations increased. Nevertheless, the HI showed a decline as the concentrations increased, suggesting a detrimental effect on growth efficiency. The study shows the potential of wild barley as a bio-herbicide, emphasizing its allelopathic effects. This suggests that agricultural practices should be carefully considered to maximize the efficiency of crops. Incorporating these results into precision agriculture can greatly improve crop management and increase yield.

Published: October 2024

In Erbil City, municipal wastewater (MWW) is disposed directly without any treatment processes in the natural environment water body and in some places used for irrigation purposes. Untreated MWW causes problems for the environment, and people's health. Water quantity and quality variation produce complications for water sources in Erbil City, Kurdistan Region-Iraq. There is a lack of performing MWW management fundamentals in the area as well. This research aimed to study the MWW management in Erbil City, presenting water resource difficulties and bringing about suitable solutions for the water resource problems, and also to highlight the risk for the poor Management. MWW Data on Erbil municipal (EMWW) water quality parameters were collected and analyzed for the study period (four months), beginning in October 2022 and ending in March 2023. Twelve EMWW quality parameters were captured and tested in the Laboratory, arranged, and compared with MWW disposal criteria and local standards. The following MWW parameters include pH, electrical conductivity (EC), total dissolved salts (TDS), chloride (CL), total solids (TS), total alkalinity, total acidity, chemical oxygen demand (COD), and colour. The results showed that Erbil's MWW characteristics in terms of temperatures ranged between 11-23 °C and in turn, affected biological species activities. Maximum PH value was 7.7. Total alkalinity found in the range from 140 to 178 mg/l. Chloride concentration results showed for October was 62 mg/l and the maximum value was 80 mg/l in November due to the increment in temperature and evaporation. The range of the COD values of sewage water for five months was 246 -773 mg. Erbil's MWW's moderate to medium strength may be treated and utilized for landscaping, fountains, and irrigation, minimizing the need for fresh water from resources like wells and surface water in the Greater Zab River.

Published: October 2024

INTRODUCTION: Moderate to severe pain after gynecological surgery has an impact on postoperative recovery and mobilization. Transversus Abdominis Plane (TAP) block and Erector Spinae Plane (ESP) block have been used as multimodal analgesia for abdominal surgery. OBJECTIVES: This study aims to compare postoperative pain in patients undergoing either ESP blocks or TAP blocks, and the need for postoperative morphine in patients undergoing gynecological surgery.MATERIALS AND METHODS: This was a single-center, prospective, double-arm, comparative study. Forty subjects were enrolled in this study, and classified into two groups. One group of 20 subjects underwent ESP block, and the remaining 20 subjects underwent TAP block following a gynecologic surgical procedure. Patients were then assessed using with the Numeric Rating Scale (NRS) pain score which will be observed at intervals of 0–1 hour, 1–6 hours, 6–12 hours, and 12–24 hours. Numerical data analysis was done using an unpaired T-test on normally distributed data and the Mann-Whitney test on non-normally distributed data. Categorical data analysis was done using Fisher's Exact Test.
RESULTS: NRS score at rest was higher in the TAP block group at 1–6 hours and 6–12 hours (pain scale 3) than in the ESP block group (pain scale 1). Movement-evoked pain NRS score was higher in the TAP block groups significantly.
CONCLUSION: ESP block results in a lower postoperative pain score NRS value and reduces the need for morphine in post-gynecological surgery patients with a median incision compared to the TAP block.

Key Points

This is the largest US cohort study investigating neighborhood socioeconomic deprivation and outcomes among pediatric kidney transplant recipients.High neighborhood deprivation was associated with worse graft survival and lower access to preemptive and living donor transplantation.Findings demonstrate inequities in pediatric kidney transplantation associated with neighborhood-level factors that warrant intervention.

Background
Social determinants of health shape a child's transplant course. We describe the association between neighborhood socioeconomic deprivation, transplant characteristics, and graft survival in US pediatric kidney transplant recipients.

Methods
US recipients younger than 18 years at the time of listing transplanted between January 1, 2010, and May 31, 2022 (N=9178) were included from the Scientific Registry of Transplant Recipients. Recipients were stratified into three groups according to Material Community Deprivation Index score, with greater score representing higher neighborhood socioeconomic deprivation. Outcomes were modeled using multivariable logistic regression and Cox proportional hazards models.

Results
Twenty-four percent (n=110) of recipients from neighborhoods of high socioeconomic deprivation identified as being of Black race, versus 12% (n=383) of recipients from neighborhoods of low socioeconomic deprivation. Neighborhoods of high socioeconomic deprivation had a much greater proportion of recipients identifying as being of Hispanic ethnicity (67%, n=311), versus neighborhoods of low socioeconomic deprivation (17%, n=562). The hazard of graft loss was 55% higher (adjusted hazards ratio [aHR], 1.55; 95% confidence interval [CI], 1.24 to 1.94) for recipients from neighborhoods of high versus low socioeconomic deprivation when adjusted for base covariates, race and ethnicity, and insurance status, with 59% lower odds (adjusted odds ratio [aOR], 0.41; 95% CI, 0.30 to 0.56) of living donor transplantation and, although not statistically significant, 8% lower odds (aOR, 0.92; 95% CI, 0.72 to 1.19) of preemptive transplantation. The hazard of graft loss was 41% higher (aHR, 1.41; 95% CI, 1.25 to 1.60) for recipients from neighborhoods of intermediate versus low socioeconomic deprivation when adjusted for base covariates, race and ethnicity, and insurance status, with 27% lower odds (aOR, 0.73; 95% CI, 0.66 to 0.81) of living donor transplantation and 11% lower odds (aOR, 0.89; 95% CI, 0.80 to 0.99) of preemptive transplantation.

Conclusions
Children from neighborhoods of high socioeconomic deprivation have worse graft survival and lower utilization of preemptive and living donor transplantation. These findings demonstrate inequities in pediatric kidney transplantation that warrant further intervention.

Key Points

Short-term changes (deltas) in concentrations of 40 circulating proteins were good predictors of fast development of ESKD in diabetes.Comparing deltas and baseline concentrations of circulating proteins predicting ESKD, we distinguished biomarkers of initiation, progression, or both.Biomarkers of initiation and progression predominantly included proteins flagging apoptosis processes and TNF receptor signaling pathways.

Background
Limited knowledge exists regarding short-term changes/increases in concentrations of circulating proteins (referred here as deltas) and rapid development of kidney failure (rapid KF) in diabetes mellitus.

Methods
Concentrations of 452 circulating proteins were measured using the OLINK proteomics platform at baseline and after a median interval of 3–4 years in 106 individuals with type 1 and 77 with type 2 diabetes in two case–control studies. During 10-year follow-up, 31 and 26 individuals, respectively, developed rapid KF.

Results
Deltas for 40 proteins predicted rapid KF in both studies. All were better predictors than delta urine albumin–creatinine ratio, and half were better than delta glomerular filtration rate. Comparing the delta proteins with 46 circulating proteins of which elevated baseline concentrations were predictors of rapid KF risk in our previous study, 61 unique proteins were identified. Among these proteins, 21 were good predictors of rapid KF only when measured at baseline (predictors of initiation), 15 were good predictors when measured as deltas (predictors of progression), and 25 were good predictors when both baseline and delta concentrations were used (predictors of initiation and progression). An index score, developed for the latter 25 proteins, provided superior prediction of rapid KF. A subset of these latter proteins was associated with apoptotic processes/TNF receptor signaling pathways.

Conclusions
Development of rapid KF in diabetes was preceded by elevated concentrations of multiple circulating proteins both at baseline and during short-term follow-up. Comparing baseline and short-term changes in concentrations of circulating proteins classified predictors of rapid KF risk into those associated with initiation, progression, or both. Predictors of both initiation and progression flagged apoptosis processes and TNF receptor signaling pathways. Multiprotein prognostic algorithms using proteins associated with both initiation and progression improved prediction of rapid KF risk beyond clinical variables.
ON THE EXISTENCE AND EXAMPLES OF HOMOGENEOUS GEODESICS IN GENERALIZED m-KROPINA SPACE

Published: October 2024

In this paper, we find a necessary and sufficient condition for a non-zero vector to be a geodesic vector in homogeneous generalized m-Kropina space. Further, we prove the existence of at least one homogeneous geodesic. However, it is conjectured that the outcomes and proofs in the case of Finsler geometry are not ideal, since general Finsler metrics are non-reversible. In Finsler geometry, the trajectory of unique homogeneous geodesic should be regarded as two geodesics with initial vectors X and -X. Hence, we construct an (n + 1)-dimensional and a 4-dimensional space to find homogeneous geodesics explicitly.
