Sistem Deteksi Dini Penyakit Preeklampsia Melalui Perubahan Warna Urine Berdasarkan Protein dengan Menggunakan Metode NaÃ¯ve Bayes Classifier
Authors: Allaam Fakhrul , Prasetio Barlian Henryranu , Maulana Rizal
Published: August 2023

Umumnya preeklamsia adalah penyakit komplikasi yang sering dialami pada ibu hamil.Penyakit ini terjadi dikarenakan adanya tekanan darah tinggi, tanpa edema atau bengkak dan disertai protein dalam urin (proteinuria).Kondisi ini kebanyakan dapat terjadi pada usia kehamilan timester 2 dan trimester 3 atau lebih dari 20 minggu. Ada beberapa teknik untuk mengetahui penyakit tersebut,salah satunya dengan dengan melihat kondisi urin. Namun, ketika penentuan status urin secara manual, sering mengalami kesalahan, karena proses diagnosis hanya menggunakan kasat mata sebagai indikator utama. Oleh karena itu, sistem diagnosa otomatis diperlukan untuk mengurangi kesalahan manusia dan memastikan bahwa pasien menerima perawatan yang mereka butuhkan. Informasi fitur warna diperoleh menggunakan sensor TCS 34725 untuk eksperimen ini. Ada tiga keadaan urin berbeda yang diidentifikasi dan diberi label sebagai Urine Normal, Urine Preeklampsia 1, dan Urine Preeklampsia 2. Titik referensi ditemukan sebagai Urine Normal. Proses klasifikasi menggunakan metode Naive Bayes yang merupakan salah bidang ilmu pengetahuan pola.Metode ini digunakan karena memberikan kemudahan implementasi dan komputasi yang cepat agar prediksi real-time dapat dilakukan.AbstractGenerally, preeclampsia is a complication disease that is often experienced by pregnant women. This disease occurs due to high blood pressure, without edema or swelling and accompanied by protein in the urine (proteinuria). This condition can usually occur in the 2nd and 3rd trimester of pregnancy or later 20 weeks. There are several ways to find out the disease, one of which is by looking at the condition of the urine. However, in the process of determining the condition of the urine manually, errors often occur because the analysis process only uses the naked eye as the main parameter. Therefore, a tool that can perform automatic analysis is needed to minimize errors in the process and take action on patients. This study uses a TCS 34725 sensor to perform feature extraction in the form of color. Urine conditions are divided into three classes, namely Normal Urine, Preeclampsia 1 Urine and Preeclampsia Urine 2. The classification process uses the Naive Bayes method which is one of the fields of pattern science. This method is used because it provides easy implementation and fast computation so that real-time predictions can be made.

Using a cross-sectional research design, the men’s dataset of the 2018 Nigeria Demographic and Health Survey (NDHS) and a weighted sample size of 7,991 sexually active married men (15–59 years) were used to examine determinants of the use of contraceptive methods. Data were analyzed using frequency tables, proportions, Pearson’s chi-square, and multinomial logistic regression. The relative risk of using male-controlled contraception relative to not using any contraception was 3% significantly lower (arrr = 0.7, 95% CI [0.5, 1.0], p < .05) among polygamous married men than for monogamists. In comparison, the relative risk of using female-controlled contraception relative to not using any contraception was 4% significantly higher (arrr = 1.4, 95% CI [1.0, 2.0], p <.05) for polygamous married men compared to the corresponding risk for monogamists. Other factors influencing the risk of using male-controlled contraception include tertiary education (arrr = 2.8, 95% CI [1.9, 4.0], p < .05), Yoruba (arrr = 3.8, 95% CI [2.8, 5.2], p < .05), richer (arrr = 1.5, 95% CI [0.8, 1.7], p < .05), and desire for more children (arrr = 0.8, 95% CI [0.7, 0.9], p < .05), media exposure (arrr= 1.5, 95% CI [1.3, 1.7], p < .05) and the number of sexual partners in the last 12 months (arrr = 5.7, 95% CI [4.6, 7.0], p < .05). Findings suggest strengthening male-controlled contraceptive methods by sexually active married men to reduce high fertility levels.

Intimate partner violence against women is a global concern. Over the years, the occurrence of such violence has recorded a significant increase, especially in developing countries, including India. The present study aims to investigate the prevalence of IPV in India. The study also seeks to determine the demographic and socio-economic factors associated with IPV. The study utilizes the fourth-round data of the National Family Health Survey 2015–2016. Chi-square (χ2) test and binary logistic regression model were used to determine IPV-related factors. Of 62,716 married women surveyed, 30.59% were found to have suffered from IPV. The prevalence of physical, sexual, and emotional violence against married women was 26.98%, 6.45%, and 12.07%, respectively. Women belonging to the following categories were found to have a higher likelihood of experiencing IPV: (i) women with higher educational attainment than their husbands; (ii) women involved in manual work, (iii) women having more than two children, and (iv) women belonging to the Muslim community. In addition, women earning more than their partners, women practicing independent decision-making, and women with partners addicted to alcohol consumption were also at higher risk of experiencing IPV. The alarming rate of IPV in India needs urgent attention. The need of the hour is to organize context-specific and community-based IPV awareness programs. In this regard, collaboration with various stakeholders and non-government organizations may help minimize the incidence of IPV in the country.

Published: August 2023

The early detection of liver cirrhosis biomarkers is crucial for timely medical intervention and improved patient outcomes. In this study, we present the fabrication of a novel colorimetric sensor based on porphyrin derivatives for the specific and sensitive detection of a prominent liver cirrhosis biomarker. The sensor design capitalizes on the unique optical properties of porphyrins, allowing for a rapid and visually detectable response upon biomarker binding. The synthesis and characterization of the porphyrin receptor are detailed, highlighting its structural and spectroscopic properties. The sensor's performance was evaluated using RGB analysis demonstrating exceptional selectivity and sensitivity towards the target biomarker. Importantly, the sensor's response mechanism is elucidated, shedding light on the underlying molecular interactions. The proposed porphyrin-based colorimetric sensor offers a promising avenue for the early diagnosis of liver cirrhosis, paving the way for point-of-care applications and enhancing disease management.
Thermoelectric CO2RR electrolysis
Authors: Berlinguette Curtis , Soni Abhishek , Lu Xin , Zhou Chris , Singh Sneha
Published: August 2023

We report here a fully contained electrolyzer that drives the CO2 reduction reaction (CO2RR) with thermoelectric generators instead of a potentiostat. The thermoelectric generators generate the electricity required to drive electrolysis when the temperature difference between the two faces is at least 40 oC. We show that the temperature gradients that could exist at a geothermal plant are sufficient to drive the reduction of gaseous CO2 into CO in an electrochemical flow cell, creating an opportunity to use waste heat to help decarbonization and clean fuels production. We also show how the electrolyzer system may be relevant to the future colonization of Mars, where there are large temperature differentials and an atmosphere rich in CO2.

Published: August 2023

Biosynthetic modifications of the 6/10-bicyclic hydrocarbon skeletons of the eunicellane family of diterpenoids are un-known. We explored the biosynthesis of a bacterial trans-eunicellane natural product, albireticulone A (3), and identified a novel isomerase that catalyzes a cryptic isomerization in the biosynthetic pathway. We also assigned functions of two cyto-chromes P450 that oxidize the eunicellane skeleton, one of which was a naturally evolved non-functional P450 that when genetically repaired, catalyzes allylic oxidation. Finally, we describe the chemical susceptibility of the trans-eunicellane skeleton to undergo Cope rearrangement to yield inseparable atropisomers.

Authors: Matar Samir F. , Solozhenko Vladimir L.
Published: August 2023

In the framework of a crystallochemical approach, new hexagonal (P63/mc) sp3-bonded BN polytypes (4H, 6H and 8H) and ternary BC2N were proposed by rationalized substitutions of C for B and N in hexagonal carbon allotrope C8 (4C carbon) with cfc topology, and density functional theory calculations of their ground states were performed. All new phases were found to be cohesive and stable mechanically (elastic constants) and dynamically (phonon band structures). According to modern models of hardness, the new phases were recognized as superhard with Vickers hardness above 50 GPa. Their electronic band structures exhibit insulating behavior with large band gaps.
Tuning the electrochemical performance of covalent organic framework cathodes for Li- and Mg-based batteries: the influence of electrolyte and binder
Authors: Luzanin Olivera , Dantas Raquel , Dominko Robert , Bitenc Jan , Souto Manuel
Published: August 2023

Covalent organic frameworks (COFs) are crystalline porous organic polymers that have recently emerged as promising electrode materials for rechargeable batteries. Herein, we present an approach to improve the electrochemical performance of an anthraquinone-based COF (DAAQ-TFP-COF) cathode material in metal anode (Li, Mg) based batteries through proper selection of the electrolyte and binder. Our results show that the combination of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in tetraethylene glycol dimethyl ether (TEGDME) as electrolyte and poly(tetrafluoroethylene) (PTFE) as binder led to the best electrochemical performance with high utilisation efficiency of the redox sites and specific capacities close to the theoretical value. Using such electrolyte and binder, cyclable symmetric cells consisting of two DAAQ-TFP-COF organic electrodes exemplify 82% capacity retention after 1300 cycles at a high current density of 500 mAh g-1. The high reversibility and stability of the COF electrode material upon cycling were confirmed by ex situ IR spectroscopy. In addition, DAAQ-TFP-COF was explored as cathode in magnesium cells using two different Mg electrolytes; one based on MgCl2 and one containing weakly coordinating anions. Electrochemical characterisation reveals significant differences in the performance of COF in terms of achievable capacities and voltage profiles, pointing towards hindered transport. Our findings demonstrate that the appropriate choice of electrolyte and binder is crucial to maximise the performance of COF-based materials in different post-lithium-ion metal anode batteries.

Interconversion of the oxidation states of uranium enables separations and reactivity schemes involving this element and contributes to technologies for recycling of spent nuclear fuels. The redox behaviors of uranium species impact these processes, but use of electrochemical methods to drive reactions of well-defined precursors and to obtain molecular insights into the outcomes has received less attention than it deserves. Here, we show that electro-reduction of the uranyl ion (UO22+) can be used to promote stepwise functionalization of the typically unreactive oxo groups with exogenous triphenylborane (BPh3) serving as a moderate electrophile. Parallel electroanalytical, spectrochemical, and chemical reactivity studies, supported by spectroscopic findings and structural data from X-ray diffraction analysis on key reduced and borylated products, demonstrate that our electrochemical approach largely avoids undesired cross reactions and disproportionation pathways; these conventionally impact the multicomponent systems needed for uranyl functionalization chemistry. Joint computational studies have been used to map the mechanistic pathways involved in this U–O activation, and to quantify free energy changes associated with key reactions. Taken together, the results suggest that electrochemical methods can be used for selective interconversion of molecular actinide species, reminiscent of methods commonly employed in transition metal redox catalysis.
Trimethylation enhancement using diazomethane (TrEnDi) enables enhanced detection of glufosinate and 3-(methylphosphinico)propionic acid from complex canola samples

Published: August 2023

Over the past century, agriculture practices have transitioned from manual cultivation to the use of chemical herbicides for improved crop yields. The most common weedkiller glyphosate (GLY) has been used exponentially worldwide, leading to the emergence of GLY-resistant weeds. This has prompted a need for effective alternatives, leading to the development and increasing use of phosphinothricin, also known as glufosinate (GLUF). As the agricultural application of GLUF rises, the potential for long-term residual exposure in the food chain increases, highlighting the need for improved analytical strategies for its detection, as well as its main breakdown product 3-(methylphosphinico)propionic acid (MPPA). Chemical derivatization strategies have been developed to improve the detection of GLUF and MPPA via liquid chromatography tandem mass spectrometry (LCMS) analyses. In this article, we expand the use of trimethylation enhancement using diazomethane (TrEnDi) to quantitatively derivatize these analytes into permethylated GLUF ([GLUFTr]+) and MPPA ([MPPATr+H]+). Comparing [GLUFTr]+ and [MPPATr+H]+ to underivatized counterparts, TrEnDi yields 2.8-fold and 1.7-fold improvements in reversed-phase chromatographic retention, respectively, while MS-based sensitivity is enhanced 4.1-fold and 11.0-fold, respectively. Initial analytical improvements were performed on commercial standards; however, successful analyte derivatization (with >99% yields) was also demonstrated on a commercial herbicide solution imparting consistent analytical enhancements. To investigate the benefits of TrEnDi in a bona fide agricultural scenario, the quantities of GLUF and MPPA were determined in aqueous extracts from field-grown canola plants before and after TrEnDi derivatization. In their underivatized forms, GLUF and MPPA were undetectable in all field samples whereas [GLUFTr]+ and [MPPATr+H]+ were readily quantifiable using the same analysis conditions. Our results demonstrate that TrEnDi continues to be a useful tool to enhance the analytical characteristics of organic molecules that are traditionally difficult to detect.
A simple method for rheological measurements of air sensitive samples
Authors: Russell Ben , Wynne Klaas
Published: August 2023

Rheology of air- or moisture sensitive liquids, gels, and glasses requires expensive and complicated rheometer-in-glovebox laboratory setups. Here, we demonstrate the use of a heavy-than-air cover gas, sulfur hexafluoride, and the design of a cheap and simple cover gas container that can attach to the lower geometry plate of any rheometer in order to carry out rheology experiments on air-sensitive liquids and soft solids. Rheological measurements of titanium(IV) propoxide, a moisture-from-air reactive liquid, are shown to demonstrate the effectiveness of the cover-gas method on acquiring correct temperature dependent viscosity data of the sample in the absence of polymeric reaction products.

Published: August 2023

В статье представлено описание системы мониторинга воздушной среды офисных помещений, предназначенной для оценки качества воздуха. Актуальность задачи создания систем мониторинга качества воздуха обусловлена тем, что воздушная среда, загрязненная вредными химическими веществами, может оказывать на человека негативное воздействие. Разработанная система включает информационно-измерительный и информационно-аналитический блоки, отвечающие определенным требованиям, таким как чувствительность, селективность, быстродействие и компактность. Основной задачей информационно-измерительного модуля является обнаружение и идентификация вредных химических веществ. Назначение информационно-измерительного модуля – определение концентрационных, скоростных и температурных полей, в любой момент времени, в любой точке помещения. Апробация разработанной системы проведена на основе экспериментальных исследований. В качестве загрязняющего вещества выбран бутилацетат. Источник загрязнения располагался вблизи системы вентиляции. Моделирование распространения загрязняющего вещества в помещении выполнено в программном комплексе Solidworks 2020. Получено распределение концентрации бутилацетата в офисном помещении на уровне слоя дыхания человека с учетом расположения источника загрязнения и рабочего места, а также с учетом времени года. Определены значения концентраций бутилацетата в различные моменты времени на рабочем месте сотрудника. Результаты моделирования показали, что в летний период времени за счет незначительной разницы температур наружного и внутреннего воздуха концентрация бутилацетата на рабочем месте сотрудника достигает предельно допустимых значений значительно быстрее, чем в зимний период.

В АО «ГНЦ НИИАР» проводится разработка конструкции облучательного устройства (ОУ) для проведения внутриреакторных испытаний поглощающих материалов органов регулирования ядерных реакторов. В качестве поглощающих материалов были выбран титанат диспрозия, так как это соединение обладает высокой химической и термической стабильностью, повышенной коррозионной и радиационной стойкостью. Конструкция ОУ состоит из подвески с фланцем, рабочего участка, в котором размещается образец с поглощающим материалом, разделителя потока и поглощающего экрана. Разделитель потока выполнен из стали 12Х18Н10Т. Поглощающий экран, предназначенный для уменьшения доли тепловых нейтронов в спектре, состоит из двух цилиндров, выполненных из бористой стали и алюминия, очехлованных сталью 12Х18Н10Т. В ходе работы были проведены нейтронно-физические расчеты, полученные с помощью кода MCU-FR, и теплогидравлические расчеты конструкции ОУ, полученные с помощью ПК SolidWorks. Нейтронно-физические расчеты показали, что использование экрана из бористой стали и алюминия позволяют корректировать соотношение потока быстрых и тепловых нейтронов при проведении внутриреакторных испытаний поглощающих материалов.

Результаты теплогидравлических расчетов показали, что при использовании высокотемпературной петлевой установки ВП-3 реактора СМ-3 в условиях принудительной циркуляции обеспечивается требуемый температурный режим облучения образца с поглощающим материалом из титаната диспрозия в третьем ряду отражателя РУ СМ-3.
