Regional infrastructure effects on the life satisfaction of rural and urban residents. A case study for Ecuador
Authors: Guevara-Rosero Grace Carolina
Published: August 2022

In developing countries, many households lack basic household services and the provision of utility infrastructure is uneven across regions, leaving lagged regions behind. This lack of infrastructure in specific places can affect the welfare of its inhabitants. This paper aims to measure the influence of household basic services and sub-national infrastructure activities on the individual subjective wellbeing in Ecuador. To determine how important the geographical context is for individual welfare, a hierarchical ordered logistic multilevel model is conducted. The results show that the individual heterogeneity is explained in 7% by the variation across cantons. There are 52 cantons which are above the average life satisfaction and 43 cantons below it. Findings regarding infrastructure evidence that sub-national utility projects and road infrastructure have a positive significant effect on the life satisfaction of rural residents whereas it is not significant for urban residents, indicating diminishing marginal utility of urban people. Once a satiation point is achieved, marginal utility increases are lower. As for household services, access to internet has a higher positive welfare effect than access to sewerage and access to water via pipelines.JEL codes: R28, D60, O18

UV/Vis single-crystal spectroscopic investigation of almandine-pyrope and almandinespessartine solid solutions: Part I. Spin-forbidden Fe2+,3+ and Mn2+ electronic-transition energies, crystal chemistry, and bonding behavior
Authors: Geiger Charles A. , Taran Michail N. , Rossman George R.
Published: August 2022

Aluminosilicate garnet is an excellent phase to research solid-solution behavior in silicates. Natural almandine-pyrope, {Fe3x2+,Mg3–3x}[Al2](Si3)O12, and almandine-spessartine, {Fe3x2+,Mn3−3x2+}[Al2](Si3)O12, crystals were measured by UV/Vis/NIR (~29 000 to 10 000 cm–1) optical absorption spectroscopy using a microscope. The spectra and changes in energy of several Fe2+ and Mn2+ spin-forbidden electronic transitions of different wavenumber were analyzed as a function of garnet composition across both binaries. The spectra of Alm-Pyp garnets are complex and show several Fe2+ and Fe3+ transitions manifested as overlapping absorption bands whose intensities depend on composition. There are differences in energy behavior for the various electronic transitions, whereby lower wavenumber Fe2+ transitions decrease slightly in energy with increasing pyrope component and those of higher wavenumber increase. The spectra of Alm-Sps solid solutions show both Fe2+ and Mn2+ spin-forbidden bands depending upon the garnet composition. The variations in energy of the different wavenumber Fe2+ transitions are unlike those observed in Alm-Pyp garnets. The three lowest wavenumber electronic transitions appear to vary the most in energy across the Alm-Sps join compared to those at higher wavenumber. Four narrow and relatively intense Mn2+ spin-forbidden bands between 23 000 and 25 000 cm–1 can be observed in many Sps-Alm garnets. Their transition energies may increase or decrease across the join, but scatter in the data prohibits an unequivocal determination. A consistent crystal-chemical model and Fe2+-O bond behavior, based on published diffraction and spectroscopic results, can be constructed for the Alm-Pyp binary but not for the Alm-Sps system. The spectra of the former garnets often show the presence of high-wavenumber spin-forbidden bands that can be assigned to electronic transitions of Fe3+ occurring at the octahedral site. The most prominent band lies between 27 100 and 27 500 cm–1 depending on the garnet composition. Fe3+-O2– bonding is analyzed using Racah parameters. State-of-the-art electronic structure calculations are needed to understand the precise physical nature of the electronic transitions in garnet and to interpret better UV/Vis/NIR spectra.
Experimental constraints on miscibility gap between apatite and britholite and REE partitioning in an alkaline melt
Authors: Stepanov Aleksandr S. , Zhukova Irina A. , Jiang Shao-Yong
Published: August 2022

Apatite containing 14 wt% TREO (total rare earth oxide) and coexisting with calciobritholite with 37.2 wt% TREO has been synthesized at 800 °C and 10 kbar from a felsic melt with the addition of NaCl. The analysis of the experimental products with regression analysis of time-resolved (RATR) laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) data allowed to estimate the composition of the coexisting phases. The results suggest that equilibrium has been established during the run and both apatite and calciobritholite contained REE in [Si4+REE3+] to [Ca2+P5+] solid solution, whereas the coupled substitution [Na1+REE3+] to [2Ca2+] was insignificant despite crystallization from an alkaline, Na-rich melt. The coexistence of the apatite and calciobritholite and available experimental data allowed the miscibility gap to be constrained between apatite and calciobritholite, and suggest complete miscibility between apatite and britholite above 950 °C. The melt that produced coexisting apatite and calciobritholite was characterized by a significant Cl content of (0.51 wt%) and elevated REE (526 ± 19 ppm Ce) and low-P content (112 ± 49 ppm). The change of the accessory mineral association from monazite to apatite and calciobritholite with the addition of NaCl illustrates the importance of halogens for mineral associations. The partition coefficients of britholite are similar to those of apatite and are distinguished mainly by a higher preference for REE and Th. Henry’s law was not acting for the total REE content in the melt because of the buffered system; however the partition coefficients could still be used for the prediction of the relative REE patterns for melts that generated high-REE apatite and/or calciobritholite. These results have implications for the interpretation of the phosphate associations in alkaline volcanic and plutonic rocks.
Impact of Environmental Taxation on Environmental Sustainability in Nigeria
Authors: Brown Joseph
Published: August 2022

Many nations have imposed environmental taxes to boost green development since green development has become a worldwide movement. Using a descriptive survey research approach, this study examines the influence of environmental taxes on environmental sustainability in Anambra State. The researcher devised two study questions and collected data using a self-created questionnaire. The personnel of the Anambra State Internal Revenue Service, chosen using a purposeful random sample procedure, makes up the sample size. Fifty copies of the questionnaire were administered for data collection. The data collected was analysed using the mean, standard deviation, and t-test statistics. The study found that environmental taxes encourage energy conservation and the adoption of renewable energy sources; Also, environmental taxation might create cash for governments, allowing for the reduction of other taxes or the implementation of environmental initiatives. Generally, the tax must be legal, and the rate must be predictable in order to encourage environmentally-friendly activities. It was advocated that understanding the effectiveness of environmental taxes and levies in instilling beneficial environmental behaviour is also important for ensuring that environmental pricing policies are designed in accordance with environmental aims. This research offers a practical and promising perspective on the function of environmental taxes in green growth, and it has the potential to be used in other regions and nations.

Authors:   Universidade de Uberaba, Uberaba, Brasil, Telles Márques Fernanda
Published: August 2022

Elaborado a partir de uma pesquisa de cariz etnográfico, o artigo discute conexões existentes entre violências ocorridas nas relações escolares, produção social da diferença étnico-racial e racismo estrutural. A pesquisa deu-se em uma escola pública do interior do estado de Minas Gerais, Brasil, e teve como participantes uma turma de estudantes da última série do ensino fundamental II. A imersão em campo teve uma duração de dois semestres letivos, envolvendo observação, conversas informais, registros em cadernos de campo, além da aplicação de questionários e de uma técnica de interpretação de desenhos. O percurso investigativo confirmou a presença de marcadores sociais de identidade/ diferença nas bases das principais situações de violência ocorridas no âmbito escolar, e revelou que a violência tende a ser naturalizada quando tais marcadores são étnico-raciais. Outros achados relevantes foram a estigmatização e a negação do corpo negro, compondo um quadro de normatização da branquitude no espaço escolar.

Published: August 2022

Intensitas mobilitas dari suburban menuju pusat kota terus meningkat setiap tahunnya. Pergerakan yang terjadi bervariasi menggunakan berbagai moda, baik pribadi maupun umum. Namun, pergerakan dengan kendaraan pribadi memperburuk kemacetan, sedangkan fasilitas kendaraan umum masih memiliki banyak permasalahan, salah satunya overcapacity, ketidapastian waktu tunggu, dan belum adanya integrasi antar moda. Pemerintah menyelenggarakan kereta api ringan (Light Rail Transit/LRT) sebagai solusi permasalahan transportasi tersebut dengan mengadakan sistem transportasi massal dalam Kawasan Metropolitan Jabodebek dengan Stasiun LRT Harjamukti, Depok sebagai stasiun akhir dari segmen Cawang-Cibubur. Pembangunan Stasiun LRT Harjamukti, Depok menyebabkan peningkatan aksesibilitas wilayah di area sekitar pembangunan, sehingga terjadi peningkatan kebutuhan lahan di area sekitar proyek pembangunan. Namun, keterbatasan lahan yang tersedia menimbulkan terjadinya kelangkaan terhadap lahan di kawasan tersebut, sehingga terjadi peningkatan nilai ekonomi lahan yang kemudian terefleksi dalam pembentukan harga lahan. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang mempengaruhi perubahan harga lahan, menyusun peta pola distribusi spasial harga lahan permukiman, serta menyusun peta spasial dan model harga lahan permukiman di area sekitar proyek Stasiun LRT Harjamukti, Depok. Metode yang digunakan pada penelitian ini adalah analisis karakteristik harga lahan, analisis regresi linear berganda, dan metode interpolasi cokriging. Dengan menggunakan data hasil kuesioner, observasi, wawancara, serta tinjauan terhadap data sekunder, penelitian ini memperoleh model harga lahan akhir berupa Y = 7.375.584,160 + 177.232,579X2.2 â€“ 61.060,826X2.4 + 25.075,015X2.5 + 93.258,006X4.1 + 293.584,789X5.1. Berdasarkan analisis regresi linear berganda yang dilakukan, diperoleh subvariabel luas lahan, jenis dan kualitas permukaan jalan, waktu tempuh menuju pusat kota, lebar jalan, kualitas jaringan persampahan, dan status kepemilikan lahan sebagai subvariabel yang berpengaruh secara signifikan terhadap pembentukan harga lahan di area permukiman sekitar proyek pembangunan Stasiun LRT Harjamukti, Depok.

Dukuh Atas sebagai kawasan TOD direncanakan sebagai area interchange pusat integrasi enam moda transportasi umum di DKI Jakarta, yaitu KRL, MRT, LRT, kereta bandara, Transjakarta, dan mini-Transjakarta (feeder) yang terletak di daerah strategis Segitiga Emas Jakarta yang berskala nasional-internasional sebagai pusat distrik bisnis dan pemerintahan. Namun, penggunaan kendaraan pribadi masih tinggi, mencapai 98% yang melalui ruas Jl. Jendral Sudirman dengan 60% kendaraan bertujuan akhir di Kawasan Dukuh Atas. Secara ideal, TOD mengintegrasikan antara T (transit) dan D (development), sehingga konsep ini dianggap dapat memecahkan permasalahan transportasi. Adapun penelitian ini bertujuan untuk mengidentifikasi karakteristik Kawasan Dukuh Atas sebagai salah satu dari delapan stasiun MRT yang dikembangkan menjadi kawasan TOD di DKI Jakarta. Variabel yang digunakan dalam penelitian ini terdiri dari (1) gabungan dari ITDP (2017) dengan parameter yang disesuaikan dengan Permen ATR/BPN No. 16 Tahun 2017, (2) Network-Activity-Human Model dan (3) 3V Framework/ Extended Node-Place Model. Hasil penelitian menujukkan bahwa karakteristik Kawasah Dukuh Atas masih terklasifikasi dalam kawasan TAD, alih-alih kawasan TOD. Hal ini ditunjukkan oleh tersedianya jaringan pejalan kaki, jaringan transportasi dan telah memiliki kawasan dengan 5 jenis campuran guna lahan, namun diantaranya belum memiliki keterkaitan. Karakteristik ini menggambarkan antara komponen "transit" dan "development" belum terintegrasi dan kawasan belum terkoneksi.

Public Health Information Seeking, Trust, and COVID-19 Prevention Behaviors: Cross-sectional Study
Authors: Tetteh Emmanuel Kwabena , Combs Todd , Geng Elvin Hsing , McKay Virginia Ruth
Published: August 2022

Background

Preventative health measures such as shelter in place and mask wearing have been widely encouraged to curb the spread of the COVID-19 disease. People’s attitudes toward preventative behaviors may be dependent on their sources of information and trust in the information.

Objective

The aim of this study was to understand the relationship between trusting in COVID-19 information and preventative behaviors in a racially and politically diverse metropolitan area in the United States.

Methods

We conducted a web-based cross-sectional survey of residents in St. Louis City and County in Missouri. Individuals aged ≥18 years were eligible to participate. Participants were recruited using a convenience sampling approach through social media and email. The Health Belief Model and the Socioecological Model informed instrument development, as well as COVID-19–related questions from the Centers for Disease Control and Prevention. We performed an ordinary least squares linear regression model to estimate social distancing practices, perceptions, and trust in COVID-19 information sources.

Results

Of the 1650 eligible participants, the majority (n=1381, 83.7%) had sought or received COVID-19–related information from a public health agency, the Centers for Disease Control and Prevention, or both. Regression analysis showed a 1% increase in preventative behaviors for every 12% increase in trust in governmental health agencies. At their lowest levels of trust, women were 68% more likely to engage in preventative behaviors than men. Overall, those aged 18-45 years without vulnerable medical conditions were the least likely to engage in preventative behaviors.

Conclusions

Trust in COVID-19 information increases an individual’s likelihood of practicing preventative behaviors. Effective health communication strategies should be used to effectively disseminate health information during disease outbreaks.
Spatiotemporal Analysis of Online Purchase of HIV Self-testing Kits in China, 2015-2017: Longitudinal Observational Study
Authors: Lv Yi , Zhu Qiyu , Xu Chengdong , Zhang Guanbin , Jiang Yan , Han Mengjie , Jin Cong
Published: August 2022

Background

Since the introduction of HIV self-testing by UNAIDS in 2014, the practice has been extensively implemented around the world. HIV self-testing (HIVST) was developed in China around 2015, and the online purchase of HIVST kits through e-commerce platforms has since become the most important delivery method for self-testing, with advantages such as user-friendliness, speed, and better privacy protection.

Objective

Understanding the spatiotemporal characteristics of online HIVST kit purchasing behavior and identifying potential impacting factors will help promote the HIV self-testing strategy.

Methods

The online retail data of HIVST kits from the 2 largest e-commerce platforms in China from 2015 to 2017 were collected for this study. The Bayesian spatiotemporal hierarchical model was used to investigate the spatiotemporal characteristics of online purchased HIVST kits. Ordinary least squares regression was used to identify potential factors associated with online purchase, including GDP per capita, population density, road density, HIV screening laboratory density, and newly diagnosed HIV/AIDS cases per 100,000 persons. The q statistics calculated by Geodetector were used to determine the interactive effect of every 2 factors on the online purchase.

Results

The online purchase of HIVST kits increased rapidly in China from 2015 to 2017, with annual peak sales in May and December. Five economically superior regions in China, Pearl River Delta, Yangtze River Delta, Chengdu and surrounding areas, Beijing and Tianjin areas, and Shandong Peninsula, showed a comparatively higher spatial preference for online purchased HIVST kits. The GDP per capita (P<.001) and the rate of newly diagnosed HIV/AIDS cases per 100,000 persons (P<.001) were identified as 2 factors positively associated with online purchase. Among the factors we investigated in this study, 2 factors associated with online purchase, GDP per capita and the rate of newly diagnosed HIV/AIDS cases per 100,000 persons, also displayed the strongest interactive effect, with a q value of 0.66.

Conclusions

Individuals in better-off areas are more inclined to purchase HIVST kits online. In addition to economic status, the severity of the HIV epidemic is also a factor influencing the online purchase of HIVST kits.
What do patients find on the Internet when looking for information about percutaneous coronary intervention? A multi-language cross-sectional assessment (Preprint)
Authors: Șulea Cristina M , Nadasan Valentin , Ursachi Tatiana , Toboltoc Paul C , Benedek Theodora
Published: August 2022

BACKGROUND

The Internet provides general users with wide access to medical information. However, regulating and controlling the quality and reliability of the immense volume of available data is challenging, therefore generating concerns about the consequences of inaccurate healthcare-related documentation. Several tools have been proposed in an effort to increase the transparency and overall trustworthiness of medical information present online.

OBJECTIVE

To analyze and compare the quality and reliability of information about percutaneous coronary intervention on English, German, Hungarian, Romanian, and Russian language websites.

METHODS

Following a rigorous protocol, 125 websites were selected, 25 for each language subsample. The websites were assessed concerning their general characteristics, compliance with a set of eEurope 2002 credibility criteria, and quality of the informational content (namely completeness and accuracy), based on a topic-specific benchmark. Completeness and accuracy were graded independently by two evaluators. Scores were reported on a scale from 0 to 10. The five language subsamples were compared regarding credibility, completeness, and accuracy. Correlations between credibility scores on the one hand, and completeness and accuracy scores, on the other hand, were tested within each language subsample.

RESULTS

The websites’ compliance with credibility criteria was average at best with scores between 3.0 and 6.0. In matters of completeness and accuracy, the website subsets qualified as poor or average, with scores ranging from 2.4 to 4.6 and 3.6 to 5.3, respectively. English language websites scored significantly higher in all three aspects, followed by German and Hungarian language websites. Only German language websites showed a significant correlation between credibility and completeness.

CONCLUSIONS

The quality of websites in English, German, Hungarian, Romanian, and Russian language about percutaneous coronary intervention was rather inadequate and may raise concerns regarding their impact on informed decision-making. Using credibility criteria as indicators of information quality may not be warranted as credibility scores were only exceptionally correlated with content quality.
Health Literacy Mediates the Relationships of Cognitive and Physical Functions with Health-related Quality of Life in Older Adults: Cross-sectional Observational Study (Preprint)
Authors: CHOW Bik Chu , DUONG Tuyen Van , JIAO Jiao , HASSEL Holger , KWOK Timothy C. Y. , NGUYEN Minh Hoang , LIU Hua Xuan
Published: August 2022

BACKGROUND

Declines of cognitive function (CF) and physical function (PF) are two irreversible health conditions linked closely to the elderly’s health-related quality of life (HRQoL). Health literacy (HL) represents the abilities for individuals to cope with health issues, and shows a positive effect on HRQoL. This research hypothesized that HL may act as a partial mediator between CF together with PF and HRQoL.

OBJECTIVE

This research aimed to determine the model of relationships of CF and PF with HL that contributes to the HRQoL of older adults in Hong Kong

METHODS

Older adults aged 50-80 years old were recruited through social media and community centers from March to July 2021. HL was assessed using the 12-item Short-Form Health Literacy Survey Questionnaire (HLS-SF12). CF was assessed using Montreal Cognitive Assessment (MoCA). PF was assessed using the Senior Fitness Test (SFT). HRQoL was assessed using the 12-item Short Form Health Survey version 2 (SF-12v2). The mediating effects of HL was tested with path analysis based on the proposed theoretical model.

RESULTS

Totally, 490 older adults completed the survey. Results for direct effects indicated that CF significantly predicted PF (β=.115, SE=.012, p <.001), PF significantly predicted HL (β=.101, SE=.022, p<.001), and HL significantly predicted HRQoL (β=.457, SE=.049, p<.001). Meanwhile, PF significantly predicted HRQoL directly (β=.150, SE=.025, p<.001) as well as indirectly (β=.046, 95% CI [.028, .067]).

CONCLUSIONS

A mediational model was hypothesized and tested in the current study to explore the relationships of CF and PF with HL that contributes to the HRQoL. These findings partially supported the hypotheses, highlighting the effect of health literacy on improving older adults’ HRQoL under the influences of both CF and PF together. This study may contribute to further empirical research and health promotion intervention programs that aim to improve HL that leads to better quality of life for the elderly population.

Psychology of Astronauts and a Metamemetic Approach Using Citizen Science
Authors: Cardinal Monique
Published: August 2022

Regarding studies that prepare astronauts for space missions, psychologists have assessed candidates’ qualifications. The following proposal is to collect astronaut diaries and look for trends in management skills for future astronauts in psychologically draining and risky situations. In the long term, approaches can be made and/or applied to prepare them for future space missions. This includes acknowledging the relationships individuals have to uncertainty, including productivity and sustaining cognitive aloneness (intended as a cognitive skill capable of limiting the interference of external thoughts and psychologies). Points of the proposed methodology include multilogical thinking skills, first principles thinking, trained attentiveness, and critical thinking as it pertains to communication, organization, self-regulation, and allowing people the time and silence needed to properly respond. Lastly, individuals should separate the interference of thoughts as a result of psychological conditioning (including biases) from applied critical thinking.
Factors Influencing Domestic Tourism in Tanzania: A Case of Arusha City
Authors: Mato Mary , Mosoma David
Published: August 2022

Domestic tourism is practiced worldwide. It greatly contributes to the number of visiting tourists and the national economy as well. However, it is still invisible and inadequately documented. This study intended to bridge this gap of knowledge by investigating the factors influencing domestic tourism using Arusha City, Tanzania as a case study. The study employed both qualitative and quantitative methods in data collection using semi-structured interviews and questionnaires respectively. A sample of 80 people was selected from a total population of 400 employees in eight different institutions in Arusha City. The Statistical Package for Social Scientists (SPSS), inferential and descriptive tools were used to analyse data. From this study, it was found that the major factors affecting domestic tourism in Tanzania include relatively high tax rate in the country compared to the other neighboring countries’ safaris, the cost charged for tourism services is generally unaffordable, the cost for food and drinks at attraction sites was found unaffordable, and there is low awareness of the available tourists' attractions. The study concluded that the major challenges facing domestic tourism in Tanzania are low awareness, poor quality of services provided to domestic tours, and few people having less interest in visiting the tourist attraction. The study recommends increased awareness on part of the policymakers, involvement of many stakeholders in the tourism sector, and academic institutions to develop new programs which allow students to have time to visit different attractions present in their region to instill enthusiasm in tourism industry.

Las pugnas decimonónicas por conformar instituciones políticas acordes con el Estado independiente mexicano tuvieron en la iglesia católica la contraparte del modelo de integración social que se quería nacional. Estas pugnas entre los dos poderes llegaron a su máxima expresión durante la Revolución Mexicana y el periodo conocido como posrevolucionario. Tales confrontaciones son el hilo conductor de este texto, pensado como un recuento de las medidas anticlericales dictadas desde los gobiernos federal y estatal, y su aplicación en Chiapas, así como la situación de la Iglesia en aquellos años, con especial atención a las reacciones que tuvo ante la considerada persecución religiosa.

La elaboración de jugos y conservas de frutas desempeña un rol importante en la economía nacional. El objetivo de este estudio fue evaluar la viabilidad de la implementación de estrategias de producción más limpia (PML) en una fábrica de dulce de guayaba. Se realizó un diagnóstico inicial in situ de las condiciones del proceso. Se cuantificaron entradas y salidas del proceso de elaboración y se propusieron tres opciones de PML para ser evaluadas. La generación de residuos orgánicos y el elevado consumo de agua fueron los principales problemas detectados en el diagnóstico. Las alternativas de PML consideradas fueron la elaboración de harina de semillas de guayaba, recuperación del agua de las calderas y reúso del agua de lavado. Según los resultados de la viabilidad técnica económica y ambiental realizada, estas opciones de PML presentan resultados positivos pues la relación beneficio/costo se incrementa a 1,65 (1,63 sin PML). Además, se podría reducir el consumo de agua, la generación de residuos sólidos y las emisiones de CO2 en un 80 %, 85 % y 48,3 %, respectivamente. Este estudio muestra que las estrategias de PML son opciones viables y pueden mejorar el comportamiento ambiental de pequeñas y medianas empresas alimentarias.

The advent of technologies has made allogenic transplantation a potential curative therapy for end-stage renal diseases, but the episodes of rejection still remain as one of the challenges in the post-transplant scenario. In the recent years, several human and animal studies have elucidated that gut microbial dysbiosis is closely linked with allogenic transplantation and post-transplant complications. But most of the studies focused on the use of high through-put sequencing technologies to analyze gut microbiota despite of its high cost, analysis and time constraints. Hence, in this work we aimed to study the impact of the two dominant gut phyla Firmicutes and Bacteroidetes on 38 renal transplant recipients, before and after transplantation and to find its association with allograft rejection. Significant changes (p<0.01) were observed in the relative abundances of the phyla Firmicutes and Bacteroidetes at pre- and post-transplant period. We have also found that the recipients who had an increase in Firmicutes/Bacteroidetes (F/B) ratio before transplant were highly prone to rejection in the first-year post-transplant. The Receiver Operating Characteristic (ROC) curve analysis has shown that the ratio of F/B were able to discriminate between rejection and non-rejection cases with an Area under the ROC Curve (AUC) of 0.91. Additionally, we observed that the ratio of F/B have reduced during the time of rejection postulating that gut microbial dysbiosis has more association with rejection. Thus, the assessment of F/B ratio using qPCR would be of a more practical approach for diagnosis and monitoring of graft function in a cost-effective and timely manner.

Actinomycetes are Gram-positive filamentous bacteria well known for the production of bioactive compounds. Recently, many halophilic habitats have been explored for isolation of actinomycetes that exhibit biotechnological potentials. In this investigation, a saline habitat of Rajasthan, Sambhar Salt Lake (SSL) was selected to study the actinomycetes population and Carboxy Methyl Cellulase (CMCase) production by native isolates. A total of sixteen actinomycete isolates, halotolerant and moderately halophilic, were obtained using culture-dependent methods and characterized morphologically and biochemically. They were identified as members of Streptomyces, Nocardiopsis, Pseudonocardia, Saccharospolyspora, and Microbispora. Streptomyces was the most dominating genus, followed by Nocardiopsis. Agar plate assay was used for screening the isolates for CMCase production. Thirteen were found to produce the enzyme, apparent by hydrolysis observed on media plates. The highest relative activity of 22.04 was shown by isolate SSL 14 identified as Nocardiopsis sp. by 16S rDNA sequencing studies and thus selected for further optimization studies. Maximum enzyme (1.08 ± 0.09 U/ml) was produced using medium containing Carboxy Methyl Cellulose (Carbon source) and yeast extract (nitrogen source) at 12% NaCl and pH 9.0, incubated at 30 °C for 96 h. Maximum CMCase production at high salt concentration and pH suggests that Nocardiopsis SSL 14 can be used for industrial processes that operate under excessive saline and alkaline conditions.

Published: August 2022

This study aims to isolate and characterize efficient biohydrogen generating facultative anaerobic bacteria from various samples, viz., biogas plant (BGP), municipal sewage (MS), and dairy industry treatment plant (DTP). The physicochemical properties of various untreated anaerobic sludge samples reflect the anoxic state and appropriateness of the substrate for separating biohydrogen generating bacteria. The biohydrogen producing bacterial strains were separated from methanogens using the heat-treatment method. The facultative anaerobic bacterial load of heat-treated test samples was determined viz., 27.2±0.57×106 (BGP), 21.8±0.43×106 (MS), and 18.6±0.92×106 (DTP) CFU mL-1 (Colony forming unit), which decreased from the total anaerobic bacterial load of untreated anaerobic sludge viz., 32.1±0.28×106 (BGP), 42.2±0.16×106 (MS), and 34.7±0.12×106 (DTP) CFU mL-1. The 28 predominant bacterial isolates strains were isolated from the heat-treated test samples. All 28 bacterial strains were identified using microscopic and biochemical techniques. Biohydrogen producing potential bacterial strains were screened using the Hungate technique with glucose as a carbon source. Among them, 12 strains were capable of producing biohydrogen, among these 5 strains being excellent biohydrogen producers. Based on the16s rRNA molecular sequencing, the 5 selected biohydrogen generating organisms were authenticated as viz., Salmonella bongori (MZ636759), Escherichia coli (MZ636716), Staphylococcus hominis (MZ636713), Yersinia enterocolitica (OM009292), and Shewanella oneidensis (MZ636800). The gas composition study by GC-TCD in a fermentative medium shows that Shewanella oneidensis (MZ636800) could produce the best biohydrogen (111.4±8.3 mLH2/L), followed by Salmonella bongori (MZ636759) with 98.1±2.9 mL H2/L and Escherichia coli (MZ636716) with 86.7±6.2 mLH2/L.

Abstract: The rising number of occurrences of coal grade slippage among coal suppliers and users is causing worry in the Indian coal industry.One of the most important metrics for determining coal quality is the Gross Calorific Value (GCV). As a result, good GCV prediction is one of the essential techniques to boost heating value and coal output. This system aims to estimate the GCV of the coal samples from proximate and ultimate parameters of coal using machine learning regression algorithm: the Multiple Linear Regression (MLR) and Local Polynomial Regression (LPR). The performance of this system is evaluated using Coefficient of determination (R2 ), Root Mean Squared Error (RMSE), and Mean Absolute Error (MAE) parameters. The results of the proposed system in terms of RMSE, MAE, and R2 of the MLR and LPR are observed as 0.124, 0.119, 0.414, and 0.654, 0.547, and 0.414, respectively.

Malaria is a disease caused by the parasites of the genus Plasmodium, which are transmitted by the bite of the female Anopheles mosquito. All tropical countries, including Southeast Asia, reported malaria cases. Several factors related to human behavior and the environment in which people live cause the incidence of malaria. The objective of this study was to analyze the risk factors for malaria in Southeast Asia and determine which risk variables had the greatest impact on the prevalence of malaria. This study is a review of the literature with a narrative review model using English and Indonesian journals from 2017 to 2021. The journals were obtained through the health journal provider databases Pubmed, Google Scholar, ScienceDirect, Researchgate, and Academic.edu. Malaria risk factors in Southeast Asia are influenced by behavioral and environmental factors. Behavioral factors include not use of mosquito nets, being active at night, male gender, and risky work. Environmental factors include rural areas, open-access dwellings, housing near cattle pens, and proximity to mosquito breeding sites. Changes in human behavior to avoid mosquito contact and environmental control are required to reduce the incidence of malaria.
