Examination of the Dry Density Importances in TDR Use and of the ASTM D6780 Standard Based on a New Calibration Procedure
Authors: Nachum Shay 
Published: August 2024

Abstract
The use of time domain reflectometry (TDR) to monitor soil water content at either field or laboratory scales is highly common. Regarding the soil dry density, ρd, effect on the TDR application, three main approaches are found in the literature: (1) Ignore the density issue and use calibration to evaluate the water content regardless of the density. This approach is basic, yet common. (2) Include soil density in the calibration equation and use calibration for the water content as a function of both the TDR output and soil density. In this approach, the soil density should be provided from an independent source. (3) Determined ρd from the TDR waveform. In this case both water content and ρd are set from the TDR analysis. In cases where the ρd is not available, in order to use TDR for water content measurement, a decision has to be made whether to address the density issue although it requires resources, or to neglect it. This article reviews this issue and validates the density effect using an efficient TDR calibration methodology. A calibration scheme that controls ρd of the specimen has been developed and applied. The methodology creates continuous calibration curves over a range of volumetric water content from a single test specimen. Based on the results, it has been demonstrated that the soil density has a major effect on the TDR output and it cannot be ignored. In addition, this article presents a unique examination of ASTM D6780, Standard Test Methods for Water Content and Density of Soil In Situ by Time Domain Reflectometry (TDR). The ASTM dry density estimation was found to provide reliable results; however, the gravimetric water contents estimation gives unsatisfactory results, especially for low densities.

AbstractThe ectoparasitic copepod Lernaea cyprinacea (anchor worm) has more than 100 host species among teleost fishes and affects cyprinids both in fish farms and natural waters. In addition, while L. cyprinacea infection in amphibians has been recorded in Asia, North and South America, there is no data available in the literature on their presence in Europe. In this study, we first reported L. cf. cyprinacea parasitising an anuran tadpole in Europe. Specimens of L. cf. cyprinacea were observed attached to a tadpole of the agile frog (Rana dalmatina), which was caught during fishing of crucian carp fingerlings (Carassius carassius) from a small fish pond in Hungary during the summer of 2012. The infected tadpole was collected from a rearing pond, where juvenile crucian carps were kept. The tadpole was inspected in the laboratory, and digital photos were taken. The parasites were found attached to the body-tail junction and to the leg of the tadpole (at Gosner stage 41). The parasite species was identified as L. cf. cyprinacea based on morphological traits.

AbstractPotential arrhythmias recorded by cardiac monitors using the built-in human algorithm are as follows: total number of episodes, ventricular tachycardia, asystole, bradycardia, atrial tachycardia, atrial fibrillation and the percentage of time spent in atrial tachycardia or atrial fibrillation. Long-term use of an insertable cardiac monitor (loop recorder) has been reported in one horse earlier, but its accurate role as a diagnostic tool is still unclear. The aim of the present study was to investigate the long-term applicability of the Reveal XT cardiac monitor for recording cardiac arrhythmias in adult horses. The Reveal XT cardiac monitor was implanted in 12 horses under sedation in standing position. Median duration of data recording calculated for the population was 1,169 days. The number of false positive detections of asystole and bradycardia was extremely high in all horses. For atrial fibrillation, false positive detection occurred in five and false negative detection occurred in one horse. The present study showed that the long-term use of the Reveal XT cardiac monitor is feasible, well-tolerated and the devices work reliably, without complications. The human algorithm could not be used for automatic detection of arrhythmic episodes in the study population. The device could detect atrial fibrillation in horses, but the recorded AF burden was inaccurate and the stored ECGs had to be manually interpreted. Because the human analyser algorithm of this cardiac monitor fails to identify bradyarrhythmias in horses based on our results, this instrument is not capable for accurately determining the aetiology of episodic collapse in this species.

Key Points

Among 727 children with posterior urethral valves, 32% had major adverse kidney events (death, kidney failure, or CKD) over a median of 14.2-year follow-up.Children with posterior urethral valves were at substantially higher risks of kidney failure, CKD, and hypertension than the general population.This justifies close kidney health surveillance among children with posterior urethral valves and optimized transitions to adult urologic care.

Background
Posterior urethral valves represent the most common cause of lower urinary tract obstruction in male infants (approximately 1/4000 live births). Long-term kidney outcomes of posterior urethral valves remain uncertain. We aimed to determine the time-varying risk of major adverse kidney events (MAKE) following children with posterior urethral valves into adulthood.

Methods
A population-based retrospective cohort study of all male children (<2 years) diagnosed with posterior urethral valves between 1991 and 2021 in Ontario, Canada. Comparator cohorts were (1) male general population and (2) male children with pyeloplasty (both <2 years). The primary outcome was MAKE (death, long-term KRT [dialysis or kidney transplant], or CKD). Time to MAKE was analyzed using multivariable-adjusted Cox proportional hazards models. We censored for provincial emigration or administrative censoring (March 31, 2022).

Results
We included 727 children with posterior urethral valves, 855 pyeloplasty comparators, and 1,013,052 general population comparators. The median follow-up time was 16.6 years (Q1–3, 8.6–24.5) overall. Throughout follow-up, 32% of children with posterior urethral valves developed MAKE versus 1% of the general population and 6% of pyeloplasty comparators. Their adjusted hazard ratio for MAKE was 36.6 (95% confidence interval, 31.6 to 42.4) versus the general population. The risk of developing MAKE declined over the first 5 years after posterior urethral valve diagnosis but remained elevated for >30-year follow-up. Children with posterior urethral valves were also at higher risk of death, CKD, long-term KRT, hypertension, and AKI than the general population or pyeloplasty comparators.

Conclusions
Children with posterior urethral valves are at higher risk of adverse long-term kidney outcomes well into adulthood.
Hybrid polycaprolactone/hydrogel scaffold fabrication and in-process plasma treatment using PABS
Authors: Liu Fengyuan , Mishbak Hussein , Bartolo Paulo 
Published: August 2024

A challenge for tissue engineering is to produce synthetic scaffolds of adequate chemical, physical, and biological cues effectively. Due to the hydrophobicity of the commonly used synthetic polymers, the printed scaffolds are limited in cell-seeding and proliferation efficiency. Furthermore, non-uniform cell distribution along the scaffolds with rare cell attachment in the core region is a common problem. There are no available commercial systems able to produce multi-type material and gradient scaffolds which could mimic the nature tissues. This paper describes a plasma-assisted bio-extrusion system (PABS) to overcome the above limitations and capable of producing functional-gradient scaffolds; it comprises pressure-assisted and screw-assisted extruders and plasma jets. A hybrid scaffold consisting of synthetic biopolymer and natural hybrid hydrogel alginate-gelatin (Alg-Gel) methacrylate anhydride, and full-layer N2 plasma modification scaffolds were produced using PABS. Water contact angle and in vitro biological tests confirm that the plasma modification alters the hydrophilicity properties of synthetic polymers and promotes proliferation of cells, leading to homogeneous cell colonization. The results confirm the printing capability for soft hard material integration of PABS and suggest that it is promising for producing functional gradient scaffolds of biomaterials.
Study of lipid profile and nitric oxide in chronic smokers

Published: August 2024

Cigarette smoking is associated with an increased risk of respiratory tract infections, chronic airway disease, and cardiovascular diseases, all of which may be modulated by endogenous nitric oxide. We have investigated whether cigarette smoking reduces the production of endogenous NO. Oxidative stress also alters the lipid profile in chronic smokers. With this view, we planned to assess vasodilators by determining the level of nitric oxide and lipid profile in chronic smokers. This study aims to: 1) determine the level of nitric oxide in chronic smokers. 2) estimate the level of lipid profile such as total cholesterol, HDL, LDL, VLDL, and triglycerides. Chronic smoker patients and healthy controls from Government Medical College and Hospital, Miraj, and P. V. P. G. Hospital, Sangli, were included in this study. A total of 70 clinically diagnosed chronic smokers and 70 healthy controls, all in the age group of 40 to 70 years, participated.: Serum nitric oxide level was found to be significantly decreased ( &#60;0.001) in chronic smokers as compared to the control group. Serum total cholesterol, LDL-cholesterol, and triglycerides levels were significantly increased ( &#60;0.001) in chronic smokers as compared to the control group, and serum HDL-cholesterol level was found to be significantly decreased (0.001) in chronic smokers as compared to the control. Cigarette smoking decreased exhaled nitric oxide, suggesting that it may inhibit the enzyme nitric oxide synthase. Since endogenous nitric oxide is important in defending the respiratory tract against infection, counteracting bronchoconstriction and vasoconstriction, and inhibiting platelet aggregation, this effect may contribute to the increased risks of chronic respiratory and cardiovascular diseases in cigarette smokers.
ETIKA GURU DAN MURID DALAM PERSPEKTIF TAREKAT SYADZILIYAH
Authors: Syahriza Fatwa Azmi 
Published: August 2024

Educators and students are important components in an education. Among the interesting discussions and often a problem of contemporary education in the relationship between the two is ethics. Ethics are norms related to what a teacher should do to students and what is forbidden to do, and vice versa. Specifically within the tarekat, ethics has more attention because the interaction between the murshid and the student is not only physical but also involves the minds of both. This study uses a qualitative-descriptive method and uses a literature study as data purification. The results of this study indicate that within the Syadziliyah order, the murshid must be able to maintain authority in front of his students, the murshid must know how his students are doing, and the murshid must be able to adjust the conditions/ability of his students in giving practice. Students must always remember their murshid wherever they are, students must limit the orders of their murshid properly, students may not move the murshid if there is a potential for danger.

Abstrak
Pendidik dan peserta didik merupakan komponen penting dalam sebuah pendidikan. Di antara pembahasan yang menarik dan sering menjadi problema pendidikan masa kini dalam hubungan antara keduanya adalah etika. Etika merupakan norma-norma yang terkait dengan apa saja yang harus dilakukan seorang guru terhadap murid serta apa yang dilarang untuk dilakukan, begitu juga sebaliknya. Etika dibutuhkan dalam segala institusi pendidikan. Khusus di dalam lingkup tarekat, etika memiliki perhatian yang lebih sebab interaksi antara mursyid dan murid bukan hanya sekadar secara fisik namun juga melibatkan batin keduanya. Penelitian ini menggunakan metode kualitatif-deskriptif dan menggunakan studi kepustakaan sebagai penggalian data. Hasil dari penelitian ini menunjukkan bahwa di dalam tarekat Syadziliyah seorang mursyid harus mampu menjaga wibawa di hadapan muridnya, mursyid harus mengetahui kabar keseharian muridnya, juga mursyid harus bisa menyesuaikan kondisi/kemampuan muridnya dalam memberikan amalan. Pada sisi murid, murid harus selalu mengingat mursyidnya dimana pun berada, murid harus menaati perintah mursyidnya dalam kebaikan, juga murid tidak boleh berpindah-pindah mursyid jika berpotensi menimbulkan bahaya.
An Improved Method to Calculate Gas-Lift Valve Set Pressure
Authors: Altarabulsi Khadhr , Waltrich Paulo 
Published: August 2024

Summary
This study aims to enhance the accuracy of gas-lift valve (GLV) design set pressure calculations by incorporating the effects of silicone thermal expansion, silicone compression, and dome thermal expansion. The proposed method is compared with experimental measurements and current industry methods. The analysis includes an experimental assessment of the impact of internal dome volume changes on the design set pressure, considering various silicone fill levels, pressures, and temperatures. Experimental conditions cover silicone fills of 25%, 50%, and 75%, initial pressures from 975 psig to 1,250 psig, and temperatures from 60°F to 175°F. These conditions cover the conventional operating range in the industry.
The results show that silicone expansion is the most dominant factor among silicone compression and chamber thermal expansion. The proposed method significantly improves GLV design set pressure calculations, especially for high-pressure and high-temperature conditions. The study suggests improvements in injection-pressure-operated (IPO) valve design practices to avoid multipoint injection and unloading failures. To the best of the authors’ knowledge, the impact of silicone expansion on GLV set pressure has not been investigated in the open literature. The enhanced method proposed in this research could significantly impact well unloading and production operations for wells equipped with GLVs. In addition, this work suggests an improvement on the American Petroleum Institute (API) recommended practice, especially when dealing with high-pressure, high-temperature wells and when utilizing refurbished GLVs.

Abstract

Elevated serum levels of uric acid are associated with an increased risk of hyperuricemia and gout. Recent attention has focused on the bioactive properties of plant extracts in preventing disease. Therefore, this study investigated the effects of 16 different extracts from four local plants on the inhibition of xanthine oxidase and the dissolution of uric acid, as well as the quantification of certain phytoconstituents and their haemolytic effects on human red blood cells. Results from quantitative phytochemical analysis revealed significant (p<0.0001) intra- and inter-specific variability in total phenols, flavonoids, tannins, uric acid, sodium, potassium, and calcium depending on the studied species and the type of solvent used in extraction. A total of 19 phenolic compounds were characterized and quantified using an ultrahigh-performance liquid chromatograph (UHPLC) coupled with an electrospray ionization (ESI) source operating in both negative and positive ionization modes mass spectrometry (LC-ESI-MS/MS), including phenolic acids, flavonoids and other polyphenols. The in vitro anti-gout activity results indicated that all extracts had the ability to express the inhibitory activity of xanthine oxidase and to dissolve uric acid at different levels. Therefore, the acetonic extracts of Cistus creticus and Plantago ciliata had the most significant xanthine oxidase inhibiting effect with values of 13.480±0.596 and 13.020±0.627 µg of Allopurinol/mg of dry residue, respectively. Moreover, their aqueous extracts showed the highest dissolving properties of uric acid (solubilities > 450 mg uric acid/L). These extracts also showed no toxic effect against isolated human erythrocytes and may be able to help improve the efficacy of new therapies for gouty arthritis.
Email Outreach Successfully Attracts Attention but Advocacy Techniques Do Not Further Improve Policymaker Engagement with Climate Science

Abstract

One of the most challenging aspects of climate change mitigation today is not identifying solutions but reaching political leaders with climate scientists’ existing solutions. Although there is substantial research on climate change communication, such research rarely focuses on one of the most impactful groups: policymakers. It is essential to test theoretically sound methods to increase lawmaker attention to research evidence. In a series of four rapid-cycle randomized controlled email trials (N = 6642–7620 per trial), we test three common and theoretically derived advocacy tactics to increase engagement with a climate change fact sheet sent via email (i.e., a norms manipulation, a number focused manipulation, and emotional language manipulation). In all four trials, the control message increased engagement more than the messages using advocacy tactics, measured by fact sheet clicks. This demonstrates the importance of testing communication methods within the appropriate populations, especially a population with significant influence over climate policy.
