Abstract
To improve the removal efficiency of antibiotics in moving bed biofilm reactor, suspended biochar block was prepared by the one-pot process and was used as carriers to construct a reaction device to study the treatment effect of antibiotic wastewater. The characteristics of the hanging biofilm in wastewater were investigated. And the mechanism of biochar as a biological carrier has been studied. The results showed that in the 45-day experiment, the maximum number of biofilms for suspended biochar carriers was twice 3.4 times that of the high-density polyethylene carriers. When 10 mg/L tetracycline was added to the reactor, the removal efficiency of the tetracycline removal rate was 71.85% and the chemical oxygen demand (COD), total nitrogen (TN), and NH4+-N removal efficiency reached to 89.95, 61.91 and 85.47% respectively. Suspension biochar carriers can reduce fluctuations in redox potentials, thereby improving the cellular efficiency of microorganisms. Meanwhile, it inhibits the production of soluble microbial products and extracellular polymers, reduces toxic effects, and enhances the adhesion between microorganisms and carriers. The microbial communities of the two carriers were investigated by high-throughput sequencing techniques. Suspended biochar significantly increased the relative abundance of Hydrogenophaga and Comamonas, and improved the ability of nitrification and denitrification. Comamonas could be responsible for tetracycline degradation.
HIGHLIGHTS
Suspended biochar block was prepared by a one-pot process using peanut shells, floating beads and waste electrode graphite as raw materials. The removal efficiency of the tetracycline and the biological characteristics of biofilms were investigated. The adsorption and aggregation of microorganism action were investigated using the biochar as carriers in a moving bed biofilm reactor tank.

Authors: Ye Qingqing , Li Qianhui , Li Xin 
Published: September 2022

Abstract
Biochar produced from biomass has been increasingly used as an environmentally friendly and low-cost adsorbent. This study systemically evaluated the effects of raw materials including corn straw (CS), cattle manure (CM), and cherry woods (CW) as well as pyrolysis temperature (400, 500, and 600 °C) on the physicochemical properties, such as morphological structure, element content, and surface functionality of biochars. The batch experiments of -N adsorption using anaerobic digested slurry (ADS) confirmed that CM600 (biochar derived from CM at 600 °C) had the highest adsorption capacity of 18.16 mg·g−1. The effects of coexisting ions in ADS, biochar dosage, adsorption time and initial concentration on –N adsorption from ADS by the biochars were evaluated. The results of the batch equilibrium and kinetics experiments showed that Langmuir isotherm model and pseudo-second-order kinetic model well described -N adsorption by the biochars, indicating that physical and chemical adsorption occurred simultaneously. Furthermore, compared to the biochar-modified method, the raw material-modified biochar (CM600-modified biochar) showed excellent adsorption capacity with a maximum of 69.82 mg·g−1 (284% increase) for the high -N concentration (4,000 mg·L−1) from ADS. Therefore, it was concluded that high-concentration nitrogen recovery from ADS using modified biochar was an effective method.

Background:
Lung cancer remains a leading cause of cancer mortality worldwide with many patients presenting with advanced disease.

Objective:
We reviewed the available literature for lung cancer screening using low dose computed tomography (LDCT). We reviewed the National Lung Screening Trial (NLST), Early Lung Cancer Action Program (ELCAP) and the (Nederlands–Leuvens Longkanker Screenings Onderzoek (NELSON) trials. We also look at different lung cancer risk prediction models that may aid in identifying target populations and also discuss the cost-effectiveness of LDCT screening in different groups of smokers and ex-smokers. Lastly, we discuss recent guideline changes that have occurred in line with new and emerging evidence on lung cancer screening.

Conclusion:
LDCT has been shown reduce lung cancer mortality in certain groups of current and former smokers and should be considered to help in the early diagnosis of lung cancer.

Published: September 2022

The diabetic foot is considered one of the long term diabetes complications caused by a defect in blood vessel and nerve system. This requires dealing with diabetic foot with professional medical care, so as to prevent its development in advanced stages which could end to gangrene and amputation of the foot. This study has been initiated through follow-up of twelve patients with diabetes and the presence various occlusions in lower limb artery. One patient from them was chosen for investigation, this patient has stenosis in popliteal artery and presence multiple stenosis in superficial femoral artery. This study based on analysis present case of patient and prediction for progress stenosis in superficial femoral artery till arrive semi total occlusion of the artery and interpret the occurrence of gangrene in the lower limb. The geometrical values of the artery and stenosis were acquired measured directly from the patient by using angiography device. The disease of gangrene and artery stenosis in diabetic foot has been investigated by using a simulation program (ANSYS Fluent CFD). The results of study by using four models with (75%, 90%) stenosis from original artery diameter in the healthy patient case are presented and compared with present and healthy case (without stenosis). It has been appeared, with presence of multi stenosis in superficial femoral artery for diabetic foot, and by assuming the blood to be a Newtonian fluid, a significant increase in the blood velocity and wall shear stress in the area of stenosis compared with non stenosis region. The blood flow rate was decreased constrained as the degree of stenosis increased and vice versa. Peak blood velocity is about (0.88) m/sec for healthy artery, it reaches (2) m/sec for a 42.4% stenosis (current case).The maximum velocity values were (10.36, 49.31) m/sec for 75%, 90% stenosis respectively. The maximum wall shear stress at the stenosis region varies from (1094) pa in the 75% stenosis to (15916) pa in the 90% stenosis against a values of (6.36, 380.5) pa in the healthy artery, current case respectively.

Published: September 2022

El presente artículo presenta una parte de los resultados del Proyecto de Investigación Especial -PIE, denominado “Análisis del proceso de internacionalización de la economía en el ingreso de la población rural en Colombia, como base de una política de protección social en el sector rural” el cual recoge la evolución de los principales subsectores agrícolas (Arrocero, cafetero, caña de azúcar y el cacaotero), en el que se utilizan los datos reportados en el Departamento Administrativo Nacional de Estadística -DANE y agremiaciones de productores. Los resultados analíticos y econométricos de la evolución de estos subsectores en el periodo 2011 a 2020 evidencian que la mayoría han ampliado la producción, la productividad y el valor real de las cosechas y por lo tanto el ingreso de los productores, por lo tanto, el proceso de internacionalización ha traído efectos positivos, lo cual se confirma con la modelación realizada por datos de panel. El precio es significativo en el modelo en los modelos con un nivel del 90% de confianza y signo positivo esperado, por lo tanto, es una variable clave en las decisiones de producción de los agentes. El TLC con los Estados Unidos impacta de manera positiva a los cultivos de arroz, café y caña de azúcar, pero tiene efectos negativos en la producción de cacao, y no se encuentra evidencia sólida del efecto de covid19 en la producción, pero los modelos arrojan un signo negativo, pero sin significancia estadística (Esto se puede deber a lo reciente del fenómeno y por ende a la falta de datos) evidenciando la evidente perdida en la producción de importantes renglones de la economía, pero no se encuentra afectaciones significativas en los cuatro subsectores.

Published: September 2022

One of the problems in improving the competence of Information and Communication Technology (ICT) for mathematics teachers is that the teacher has to leave his / her teaching activities to participate in various improving competence events. This study aims to develop an ICT house portal that will be managed by the Mathematics Subject Teacher Forum in Indonesia or known as MGMP that allows teachers to interact with fellow teacher communities to improve ICT competence without having to leave their teaching activities at school. Furthermore, the researchers also conducted a usability test of the developed portal. The application development model used is the ADDIE model which stands for Analysis, Design, Development, Implementation, Evaluation. Meanwhile, application usability testing was carried out by distributing usability questionnaires to 30 respondents consisting of postgraduate students and lecturers of mathematics education. The results showed that the ADDIE model can be used to design and create the ICT house portal called RumahTIK where the procedures in the development section include making applications, testing by experts, testing content filling, testing the use of clinical features. Based on the results of the usability questionnaire processing, the percentage of usability was 81% which was classified as very feasible. Although this research was not implemented for real teacher groups, the ICT house portal is very suitable for use by the MGMP group. In the future, it is necessary to implement this portal in various MGMP groups so that recommendations can be obtained to improve teachers' ICT competence in mathematics.

Published: September 2022

Secara umum proses pengembangan aplikasi terdiri dari proses perancangan, pengujian, dan deployment. Pengembangan dengan cara tradisional seringkali menimbulkan masalah seperti keterlambatan aplikasi dan kualitas produknya. Hal ini dapat terjadi karena tim operasional harus menunggu developer agar menyelesaikan proses uji coba terlebih dahulu sebelum aplikasi tersebut dapat dirilis dan diguankan. Selain itu, setelah proses pengujian selesai, sering didapati adanya konflik akibat environment yang berbeda, yang memperlambat proses rilis. Keterlambatan ini membuat klien kecewa dan memberikan efek yang tidak baik bagi perusahaan. Continuous Integration / Continuous Delivery (CI/CD) dapat dijadikan solusi untuk memecahkan masalah ini. CI/CD dapat menjadi jembatan antara tim pengembang dan tim operasional..

Los actores que habitan el espacio público pugnan por imponer sus temas y sus puntos de vista en la agenda mediática, entendiendo que existe una correlación entre ésta y la agenda pública. Sin embargo, no todos tienen las mismas posibilidades de acceso a los medios. Este estudio analiza las fuentes utilizadas por tres medios de comunicación de Almirante Brown, Esteban Echeverría y Lomas de Zamora. Para ello se hizo un relevamiento de las noticias publicadas y se procedió a un análisis de contenido. Se analizaron los temas abordados, las fuentes de información utilizadas y el grado de crédito otorgado a las mismas desde la óptica del standing. Las primeras conclusiones indican que las fuentes oficiales son las más citadas y tienen un grado de crédito medio. En ese sentido, la construcción de la agenda parece quedar en manos de la política y no de actores de otros sectores.

Authors: Ibrahim Rafiuddin 
Published: September 2022

This study discusses the extent to which Islamic business ethics affect customer retention in Islamic banking so that it can compete with conventional banking. The research method uses descriptive quantitative research, with 72 respondents from students, private employees, civil servants, and entrepreneurs. Data collection techniques in the form of observations, literature studies, and questionnaires The independent variable is the business ethics variable, with indicators of unity, justice, free will, responsibility, and virtue. As for customer retention with indicators of customer loyalty and the intensity of the implementation of transactions in Islamic banking, this survey uses simple regression analysis using IBM SPSS Statistics 20 software. The results of the study found that Islamic ethics have an influence on customer retention. This is evidenced by the percentage of Islamic ethics influence of 36.1% on customer retention, and the rest is influenced by other factors. The majority of the reasons customers choose Islamic banking are because of the application of Islamic business ethics in the operations of Islamic banks, especially on the divine side. Customers assume that Islamic banks are banks that offer a solution to avoid the practice of usury. Inclusion and literacy stimulation are needed so as to increase public preference for Islamic banks..

Plonowanie i efekty ekonomiczne produkcji pszenicy ozimej i jarej w stanowisku po buraku cukrowym
Authors: Sułek Alicja , Harasim Adam 
Published: September 2022

Badania przeprowadzono na polach produkcyjnych w trzech rolniczych zakładach doświadczalnych IUNG-PIB położonych w różnych rejonach kraju w latach 2019–2021. Celem badań było poznanie wpływu terminu siewu na plonowanie i opłacalność produkcji pszenicy ozimej i jarej w stanowisku po buraku cukrowym zbieranym późną jesienią. Oceniono plony ziarna, koszty bezpośrednie i efekty ekonomiczne produkcji pszenicy. Stwierdzono, że poziom plonów ziarna zależał od lokalnych warunków, a koszty i opłacalność produkcji od cen zakupu środków produkcji (nasion, nawozów i środków ochrony roślin) i cen zbytu ziarna pszenicy. Plony ziarna były znacznie zróżnicowane w poszczególnych miejscowościach. Na plonowanie pszenicy wpływały istotnie warunki pogodowe; w warunkach dużych niedoborów wilgoci (opadów) przeciętny poziom plonów był najniższy (ok. 4,5 t∙ha–1), a w korzystnych warunkach pogodowych osiągano plony najwyższe (ok. 6,5 t∙ha–1). W badanych lokalizacjach siew pszenicy jarej wiosną prowadził do obniżki plonów ziarna (o 0,8–1,5 t∙ha–1) w porównaniu z osiąganymi w warunkach siewu jesiennego. Na opłacalność produkcji pszenicy wpływał również dobór jej odmiany. W strukturze bezpośrednich kosztów produkcji na ogół przeważały nawozy mineralne, a mniejszy udział miały nasiona i środki ochrony roślin. Wyniki badań wskazują, że ze względu na wielkość plonu ziarna i efekty ekonomiczne produkcji bardziej jest uzasadniona uprawa pszenicy jarej (przewódkowej), wysiewanej późną jesienią niż wiosną.

We focus on transition teams and social interactions and innovation in three energy cases. In PXL University of Applied Sciences, the transition team is built using the quadruple helix framework. Arestart has been made from here to put a new M(aintenance) E(nergy) P(erformance) C(ontract) on the market for (campus) buildings. The transition team is a catalyst to include sustainability within the mission and vision. PXL is the first Flemish higher education institution to acquire the SDG Pioneer label awarded by the UN. Stedin Netbeheer, (distribution system operators) though strictly regulated, has set itself the goal of accelerating the energy transition where possible. The transition team focuses on ensuring that the technical blue-collar employees obtain more decisiveness and greater autonomy necessary to “do different” and “organize differently”. In the grassroot experiment in Haarlem the transition team improves environmental and climate indicators (reduction of CO2, NOX and particulate matter, creation of more vacant spaces, ….), together with behavioral changes. It is indicated how the transition team worked and progressed towards “coalitions for change” and how “change processes” have started. These paradigm shifts to new “energy systems” in combination with new business models and societal transition are needed to achieve a post carbon society.
