Published: July 2024

Abstract

In this work Prussian blue loaded silica (PB/Si HOM) nanocomposite has been used for removal of Cu (II) as it can act as a selective adsorption agent with negligible toxicity. A faster uptake of copper in water samples was caused by the smaller particle size, higher specific surface area, and higher pore volume values in comparison to the commercial Prussian blue. Optimum conditions are determined using Design-Expert®, version 6.0 (DX6) software applying a contact time of 24 hr with PB/Si HOM nanocomposite adsorbent. The influence of solution pH on the removal efficiency and adsorption capacity of the adsorbent was optimized to be pH 8.4. Other experimental parameters were conducted to determine their effects on the adsorption of Cu (II); It was found that the maximum adsorption 92.3% was obtained at 25°C, 60 minutes of contact time and 10 ppm of metal ions. It was discovered that the ideal amount of adsorbent material for the removal was 0.1 g. It was also discovered that the Langmuir isotherm was appropriate for the adsorption of Cu (II) than the Freundlich isotherm. The kinetic parameters and experimental adsorption capacities for copper onto PB/silica HOM nanocomposites were also studied, it is found that the system is fitted with pseudo-second order where calculated Qe is found to be 175.439 mgCu(II)/g that is very close to the Experimental Qe one (180.697 mgCu(II)/g). Therefore, the newly created environmental nanocomposite material was shown to be appropriate for the adsorption of Cu (II) due to its high adsorption capacity, high adsorption selectivity, quick adsorption speed, and good regeneration for repeated use for adsorption of copper pollutant from different water matrices.

Published: July 2024

Abstract

The agricultural sector is the major driver of revenues in India. organic , economic, and seasonal factors all have got a bearing on an agricultural producer's manufacturing.
Accurate crop yield prediction (CYP) is required due to the agricultural indus-try's rapid innovation and liberalized market economy. Accurate prediction is greatly aided by the chosen characteristics and machine learning (ML) techniques Any ML Algorithm’s performance may be enhanced by using a unique set of features from the same training dataset. This study assesses the key characteristics of an accurate crop yield prediction. For greater accuracy, it uses machine learning (ML) methods like Random Forest (RF), Adaboost, Gradient Boost, and Support Vector Machine (SVM). The agriculture dataset has 2201 instances in it. 80% of them are randomly chosen for themodeìs training, while 20% are used to test themodeìs predictive power. The results show that the Random Forest approach gets the highest level of accuracy. The goal of this paper is to predict crop yields. Using different Machine Learning Algorithms so that farmers can make their yields higher.

Abstract

How animals navigate during long-distance migration remains a mystery. Many theories have been proposed1 (Keeton, 1979), with the Earth’s magnetic field emerging as a clear potential source of orientational information for navigational decision-making across diverse taxa2 (Putman, 2022). Yet, the mechanics involved in magnetic navigation remain unknown3 (Schneider et al., 2023). Globally distributed records available from historic whaling4-5 (AOWLD, 2023; Yablokov et al., 1998) in combination with modern satellite-tracking datasets6 (Horton et al., 2022) for baleen whales create a unique opportunity to illuminate the mechanics of cetacean navigation. Here, we show that baleen whale migratory destinations over the last >200 years are systematically distributed in horizontal plane magnetic coordinates. Specifically, blue (Balaenoptera musculus), bowhead (Balaena mysticetus), fin (Balaenoptera physalus), gray (Eschrichtius robustus), humpback (Megaptera novaeangliae), and right (Eubalaena spp.) whales non-randomly inhabit areas where magnetic declination (MD) closely approximates integer and half-integer multiples of the Earth’s 23.44° axial tilt. Our findings, which are highly reproducible through both space and time, demonstrate that baleen whale navigation between seasonal habitats occurs via the integration of magnetic and astronomic orientation cues3. By referencing MD values to the rise and set azimuths of the Sun, baleen whale movements define mechanistic horizontal plane heliomagnetic coordinate trajectories across all ocean basins.

Published: July 2024

Abstract

Purpose
The aim of the study was to compare the perioperative outcomes of patients who underwent surgery performed through laparoscopy or using the Medtronic Hugo™ RAS
Methods
This is a retrospective study from a prospectively maintained database comparing laparoscopic vs. robotic assisted surgery for IBD from 01/11/2017 to 15/04/2024. All procedures were performed by a single surgeon robotic-naïve with a large experience in laparoscopic surgery for IBD. The robotic procedures were performed using the Medtronic Hugo™ RAS platform (Medtronic, Minneapolis, MN, USA). Outcome were 30-day postoperative complications, operative time, conversion rate, intraoperative complications, length of hospital stay, and readmission rate.
Results
Among 121 consecutive patients, 80 underwent laparoscopic (LG) and 41 robotic-assisted surgery (RG). Baseline, preoperative and disease-specific characteristics were comparable except for older age (50 [38–56] vs. 38 [28–54] years; p = 0.05) and higher albumin (42 [40–44] vs. 40 [38–42] g/L, p = 0.006) in the RG. Intracorporeal anastomosis was more frequent in the RG (80% vs. 6%; p < 0.001) with longer operative time (240 vs. 205min; p = 0.006), while the conversion rate was not different (5% vs. 10%, p = 0.49). Postoperative complications were similar, including the rate of intra-abdominal septic complications (5% vs. 5%, p = 1), postoperative ileus (5% vs. 7.5%, p = 0.71), bleeding (2% vs. 5%, p = 0.66) and Clavien-Dindo > 2 complications (7% vs. 6%; p = 1).
Conclusion
IBD surgery performed using the Medtronic Hugo™ RAS is safe and feasible, with similar postoperative outcomes when compared to the laparoscopic approach.

Abstract

Background
Human Cytomegalovirus (HCMV) infection is a common congenital infection that affects approximately 0.7–1% of all live births worldwide. Approximately 11% of newborns who are infected show symptoms at birth, and of these, between 30% and 40% are at a risk of experiencing long-term neurological complications. This study aimed to evaluate the effect of HCMV on hematological parameters and liver function in pregnant women in Hajjah governorate, Yemen.
Materials and Methods
This study is a cross-section study that conducted in the Hajjah governorate of Yemen during a period of March to June 2023. A total of 108 blood specimens were collected from participants; 78 from patients group and 30 health group. Hematological parameters, such as total red blood cell count (RBC), hemoglobin (HB), platelet count (PLT), and white blood cells (WBC), as well as liver function tests, such as total protein, albumin, alkaline phosphatase (ALP), serum glutamic oxaloacetic transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), total bilirubin, and direct bilirubin, were measured.
Results
Majority of participant patients aged between 16–21 years 27 (34.7%), studied at secondary schools (46.2%), in their second trimester 51 (65.4%), those with multigravida 54 (69.2%), and those with no history of congenital diseases 60 (76.9%). Compared with the control group, the mean WBC levels were significantly lower in HCMV patients (P < 0.05), whereas PLT Levels were higher among HCMV patients (P < 0.05). Additionally, the mean levels of total bilirubin, direct bilirubin, SGOT, ALP, and albumin were significantly lower in patients with HCMV than in HC (P < 0.05). Furthermore, there were no significant differences between the patient and healthy groups in terms of HB, RBC counts, SGPT, and total protein (P > 0.05).
Conclusion
It can be concluded that HCMV infection had a statistically significant effect on WBC, PLT, total bilirubin, direct bilirubin, SGOT, ALP, and albumin levels in pregnant women. Consequently, further studies are needed to define the role of HCMV in liver disorders.

Published: July 2024

Based on the results of a preliminary study at SMA Negeri 2 Garut it is known that students' activeness is still lacking and students' critical thinking skills are classified as low. In addition, limited laboratory space makes learning less than optimal because it rarely does practicum. One effort that can be done to overcome this problem is to apply the ROPES learning model. Laboratory space limitations can be overcome by practicing crocodile physics. The purpose of this study was to determine the effect of the ROPES learning model assisted by crocodile physics on students' critical thinking skills in mechanical wave material in class XI MIPA SMA Negeri 2 Garut in the 2022/2023 academic year. This study used a quasi-experimental method with a nonequivalent control group research design. Instrument of students' critical thinking skills is carried out by giving tests in the form of essays with each question consisting of one indicator of critical thinking. The results of t-test at the significance level (α=0,05) show that tcountttable which means H0 is rejected, so it can be concluded that the ROPES learning model assisted by crocodile physics has a significant effect on critical thinking skills in mechanical wave material.
Differentiated and conflicting incentives across the sanitation value chain: the case of Sanergy in Nairobi
Authors: Zaqout Mariam , Mdee Anna , Barrington Dani , Agol Dorice , Evans Barbara E. 
Published: July 2024

ABSTRACT
The challenge of achieving safely managed sanitation in low-income settlements in the context of rapid urban expansion in Nairobi is significant. National and county government plans for sanitation focus primarily on extending large-scale sewer systems, but in recent years, there has been increasing activity on non-sewered sanitation, particularly container-based sanitation (CBS) to potentially extend safely managed sanitation. Market-based CBS providers received extensive investment and promised to rapidly scale service delivery. Yet, progress has faltered, and scaling up is proving to be problematic. We apply a service characteristics analysis to examine the case of Sanergy, a CBS provider. Data are drawn from documents and stakeholder interviews. We demonstrate that misaligned incentives between stakeholders explain why extensive scaling up has (so far) failed to materialise. In particular, the creation of a self-sustaining faecal waste circular economy has proved to be elusive and highlights the need for the state to engage actively in sanitation provision as a public good.
Food Insecurity: Physician Perspectives, Screening and Communication
Authors: Heaberlin Sally , Skelly Kelly , Rosenbaum Marcy , Bunt Stephanie 
Published: July 2024

Introduction: Primary care physicians may perceive food insecurity (FI) as a difficult topic to address in health care encounters, resulting in at-risk patients not being identified. This exploratory study examines physician perspectives on how decisions to screen patients for FI are made, effective FI communication strategies, and barriers to screening.
Methods: Primary care physicians in the statewide, practice-based Iowa Research Network (IRENE) completed a study survey in May 2022 that included structured and open-ended questions regarding their experiences screening for FI. Thematic and descriptive analysis identified common themes in providers’ experiences and perspectives.
Results: Although most physicians responding to the survey indicated that they have observed FI in their patient population, 27% have never observed FI in their practice. Physicians varied in their reasons for deciding to screen, with the most reported reason being “when it comes up in conversation.” Common screening barriers among respondents included limited appointment time and feeling inadequately prepared to connect patients with resources. Respondents noted that negative experiences with FI screening were rare and noted positive experiences, including gratitude from the patient, and building patient-physician trust. Respondents shared normalizing phrases that helped address the additional obstacle of feeling inadequately prepared to assess FI in a tactful manner.
Conclusions: This study explored physicians' experiences with asking patients about FI and provides insight into FI screening gaps, barriers, and opportunities. Better understanding of physician attitudes and practices may help guide and address barriers to more effective and consistent FI screening.
Calibration complex of radio measuring equipment
Authors: Vasylieva Olena , Pavlenko Yurii , Ogar Valeriy 
Published: July 2024

Modern trends in the development of radio measuring equipment require improvement of the principles of metrological support of these devices and corresponding reference base. The new approach is based on the digitalisation of equipment, programming of measurement procedures, and the transition from single measurement standards to measurement complexes.
The paper describes the complex developed at the NSC “Institute of Metrology” and designed for verification and calibration of a wide range of radio measuring equipment, where all these approaches are realised, presents methodological, software and hardware features of its construction, as well as the advantages and possibilities of this approach in metrological practice. On the example of the method of “Bessel Function Zeros”, which was somewhat forgotten due to the cumbersome nature of its implementation by analogue methods and equipment, it is shown that with the new approach this method gets a “second birth”, moreover, at a higher metrological level.
It is shown that the use of direct digital synthesis oscillators can significantly improve the “electronic counting frequency meter” method, in particular, prevent the phenomenon of “frequency capture”, which limited the capabilities of the method and introduced additional measurement uncertainty. Moreover, the additional properties of the complex associated with the use of the R&S FSL spectrum analyser with the K7 analogue signal demodulator option are explained in more detail.
A list of other methods realised in the complex is given, among which the “combination frequencies” method, deserves a special attention, providing the highest resolution in measuring nonlinear distortions of both quasi-harmonic and modulated signals.
It is shown that the complex is a flexible apparatus, the work programme of which can be adjusted and supplemented.
Information on the structure of the complex, hardware solution of a number of nodes, programming language, etc. is given.

Published: July 2024

Objective: This study investigates the complex relationship between environmental conservation and corruption, particularly focusing on how corrupt practices such as bribery undermine efforts to protect biodiversity, climate, and species survival in Malaysia. Despite the universal religious condemnation of corruption, it remains rampant, fueled by greed and often inadequately addressed by legal systems.

Method: Through an extensive literature review of journal articles, conference proceedings, books, and online sources, this paper illustrates specific cases where corruption has directly led to environmental degradation.

Research Findings and Discussions: The findings underscore the need for robust anti-corruption strategies that are informed by both environmental science and ethical considerations to effectively safeguard natural ecosystems.
Research Implications: This study can help everyone realize that every negative activity, no matter how minor, has a significant influence on the ecosystem, which needs to be protected.

Originality/Value: Public awareness of the perils of corruption and its consequences for the environment is raised by this research. This explains why it is against religious law to engage in corruption and the need for numerous reforms to end this corrupt behaviour.

Published: July 2024

Background:
Peritoneal dialysis (PD) is an important modality of renal replacement therapy (RRT). Peritonitis and ultrafiltration failure are complications that have a long-term impact on PD patients. Besides touch contamination, procedural errors and clinical reasons of peritonitis, contaminants, and constituents of peritoneal dialysis fluids (PDFs) have been implicated in causing peritonitis and ultrafiltration failure. This study was aimed to test the PDFs in India for the presence of migratory plastics.

Materials and Methods:
PDFs from the two manufacturers in India were tested using liquid chromatography mass spectrometry (LCMS) and gas chromatography mass spectrometry (GCMS) with headspace analysis (volatile compounds) and pyrolysis of plastics (polymer compounds). The storage conditions and handling were uniform.

Results:
The results revealed impurities of acetate compounds and aldehyde derivatives of glucose degradation products (GDPs) with contaminants and leachable plastics. There were high levels of GDP derivative in the form of 5-hydroxymethylfurfural compounds (5-HMF). The analysis revealed the presence of plastic softeners in very high concentrations.

Conclusion:
The study unmasks the presence of chemicals and GDPs that can be implicated in pathogenesis of sterile peritonitis and ultrafiltration failure. The study demonstrated the presence of leachable plastics. In conclusion, LCMS and GCMS studies can be used to test PDFs for unwanted chemicals prior to human use.
