Published: May 2023

The results of the study showed that Ukrainian coal fly ash (CFA) and acid mine drainage (AMD) can be successfully processed into zeolite-like sorptive material (ZSM) to extract pollutants from AMD. This approach provides a twofold benefit: firstly, the interaction between CFA with AMD provides an alternative method of conditioning AMD. Secondly, the solid residues contain a lot of Al and Si so they can be used for the synthesis of ZSM. The synthesis was done via alkaline conversion followed by hydrothermal crystallization. ZSM can be effectively used as an ion exchanger and sorbent for the conditioning of highly saline wastewater. Mercury, which is considered a priority pollutant, can be removed to levels below the permission level. Anion species were also removed from the solution by mechanisms other than ion exchange, e. g. arsenic.
Studies discovered the following results:
- pH plays a key role in the formation of metal ions as well as the charge of the surface functional groups of the ZSM, thus changing the physicochemical interactions between the ZSM and pollutant ions.
- in addition to ion exchange, other mechanisms are also suggested, including adsorption, and the formation of complex compounds that significantly contribute to the purification process.
Given its simplicity, this technology can be implemented as the first stage in the treatment of metal-containing wastewater at an operating or decommissioned coal mining enterprise. This technology can also be implemented as part of the desalination stages at TPP treatment plants. The proposed method is based on waste utilization, so it can be considered an eco-friendly low-cost method of wastewater treatment. However, on an industrial scale, hydrothermal activation will lead to increased operating costs due to increased energy consumption. Therefore, future research should be conducted on the application of ZSM in a pilot plant.
Since this technology can be applied to the removal of both cations and anions, it will undoubtedly attract interest, provided the synthesis technology is optimized. First of all, it is necessary to optimize the synthesis method in order to use low-temperature activation methods to lessen operating costs.

Tekelan (Chromolaena odorata (L.) R. King & H. Rob) merupakan salah satu tumbuhan yang termasuk famili Asteraceae yang mana ekstrak daun tekelan telah diteliti dapat menurunkan kadar kolesterol. Kandungan kimia dari ekstrak daun tekelan seperti tanin, flavonoid, saponin dan steroid diduga membantu mempercepat penyembuhan kolesterol. Tujuan dari penelitian ini adalah untuk menguji efek antikolesterol dari ekstrak etanol daun tekelan (EEDT) pada tikus putih jantan yang diinduksi menggunakan telur puyuh. EEDT dibuat dengan metode maserasi. EEDT dibuat dalam bentuk ekstrak dengan dosis 50; 100; 200 mg. Uji aktivitas penyembuhan kolesterol dari EEDT dilakukan terhadap tikus putih jantan, yang sebelumnya telah diinduksi dengan telur puyuh secara oral dan tikus yang diinduksi digunting bagian ekor untuk pengambilan darah sebelum dan setelah induksi sama. Hewan uji yang digunakan 25 ekor dan dibagi menjadi 5 kelompok, yaitu kelompok hewan uji kontrol positif (Simvastatin 10 mg), uji kontrol negatif (CMC 0,5%), ekstrak EEDT dengan dosis 50; 100; 200 mg. Pengamatan dilakukan dengan menggunakan alat pengukur kadar kolesterol, dan diukur setiap 60 menit, dan dihitung persentase penurunan kadar kolesterol. Kemudian dilakukan analisis statistik dengan uji ANOVA menggunakan Statistical Program Service Solution (SPSS). Hasil evaluasi menunjukkan EEDT, baik terhadap pemeriksan homogenitas dengan nilai 0,512 > 0,05. Hasil penelitian menunjukkan bahwa ekstrak EEDT mempunyai efek penyembuhan kolesterol pada tikus putih jantan yang telah diinduksi dengan telur puyuh. Hasil statistik menunjukkan kelompok hewan uji dengan pemberian ekstrak EEDT pada dosis 50; 100; 200 mg berturut-turut sembuh setelah pemberiaan ekstrak EEDT dengan jangka waktu yang berbeda, dan berbeda signifikan terhadap kelompok hewan uji dengan pemberian kontrol positif dan kontrol negatif. Penyembuhan tercepat terjadi pada kelompok hewan uji dengan pemberian ekstrak EEDT dosis 200 mg. Dapat disimpulkan bahwa ekstrak EEDT mempunyai aktivitas penyembuhan kolesterol pada tikus putih jantan dan penyembuhan tercepat terjadi pada kelompok hewan uji dengan pemberian dosis 200 mg.
Evaluating Just Transit-Oriented Development Planning in the Community of Jefferson Park, Chicago
Authors: Alimovski Ismail 
Published: May 2023

<p>Transit-Oriented Development (TOD) is a specialized planning framework used for coordinating land-use around transit stations. A common approach with TOD is to promote a heterogenous mix of land-uses along with design upgrades to support smart growth and increased transit access (Cervero, 2004). This does not mean that public officials should simply change density guidelines to increase ridership. To achieve optimal success, scholars have determined that planners should take the opportunity to create a community-lead and focused comprehensive plan. Defining a community’s relationship to local infrastructure requires planners to be mindful of whether the bureaucratic process they follow is actually achieving or missing the true <em>‘collective vision’ </em>(Forester, 1982; Baum, 1983). Therefore, the purpose of this Major Research Project is evaluating current literature as well as the progress of an ongoing TOD plan to create a concise strategy for just TOD planning practice. Moreover, this paper will provide suggestions for actions that the community could follow to support civic engagement. </p>
<p>This paper looks at the current progress of the Jefferson Park Community Master Plan (2018), a TOD plan for the respective community on the northwest side of Chicago, Illinois. This site was chosen due to its history as a commuter suburb and its prime location as a transit hub on the outskirts of the city. The respective hub services all of the region’s transit agencies, is divided by high-volume freeway, and has a strong community network involved in local affairs. First, I consult existing literature and articles to determine the best practices for enabling Just TOD in this community. Second, I conduct a study examining whether the plan’s proposed actions are being implemented in reality. I then propose a new set of values, action items and a community hub that further achieves the community-oriented vision that the plan focuses on. </p>

Work by digital platforms in Germany
Authors: Da Penha de Mendonça Coelho Bruna 
Published: May 2023

The paper aims to analyse the characteristics of the labour relations by digital platforms in Germany, focusing on two dimensions: the understanding of these relations in the context of changes and inequalities of the labour market in that country, as well as its interpretation in German normative framework and in Bundesarbeitsgericht’s 9 AZR 102/20 decision. Regarding the methods of analysis, the study combines bibliographic and empirical research. The development of the article is divided into three items: (i) a sociological analysis on the insertion and diffusion of this labour relation in the German labour market; (ii) the German legal system and the Bundesarbeitsgericht’s decision under analysis; (iii) possible theoretical-empirical precautions for future comparative research on the topic between Germany and Brazil. In the final considerations, the main challenges observed throughout the study are taken up again, based on the assumption that legal normativity should not be understood in isolation from social relations.

Published: May 2023

Objective: Developing a simple, rapid, reliable, sensitive, and cost-effective method for prenatal detection of fetomaternal haemorrhage by combining multi-aperture silk membrane with enzyme-linked immunosorbent assay (ELISA), which does not require any complicated instruments and can be visually colored, so as to provide a new method for clinical detection of fetomaternal haemorrhage.Methods: As a carrier, a chemically treated silk membrane was used to immobilize anti-A/anti-B antibody reagent. PBS washed slowly after vertically dropping red blood cells. After adding biotin-labeled anti-A/anti-B antibody reagent, PBS is slowly washed, enzyme-labeled avidin is added, and TMB is used for color development after washing.Results: When there were both anti-A and anti-B fetal erythrocytes in pregnant women’s peripheral blood, the final color was dark brown. When there are no anti-A and anti-B fetal red blood cells in pregnant women’s peripheral blood, the final color development results do not change, which corresponds to the color of chemically treated silk membrane.Conclusion: The new enzyme-linked immunosorbent assay (ELISA) based on a silk membrane can distinguish fetal red blood cells from maternal red blood cells prenatally and can be used for prenatal detection of fetomaternal haemorrhage.

BackgroundIt has been shown that increased aortic stiffness is related to type-2 diabetes (T2D) which is considered as a risk factor for cardiovascular disease. Among other risk factors is epicardial adipose tissue (EAT) which is increased in T2D and is a relevant biomarker of metabolic severity and adverse outcome.PurposeTo assess aortic flow parameters in T2D patients as compared to healthy individuals and to evaluate their associations with EAT accumulation as an index of cardiometabolic severity in T2D patients.Materials and methodsThirty-six T2D patients as well as 29 healthy controls matched by age and sex were included in this study. Participants had cardiac and aortic MRI exams at 1.5 T. Imaging sequences included cine SSFP for left ventricle (LV) function and EAT assessment and aortic cine and phase-contrast imaging for strain and flow parameters quantification.ResultsIn this study, we found LV phenotype to be characterized by concentric remodeling with decreased stroke volume index despite global LV mass within a normal range. EAT was increased in T2D patients compared to controls (p&lt;0.0001). Moreover, EAT, a biomarker of metabolic severity, was negatively correlated to ascending aortic (AA) distensibility (p=0.048) and positively to the normalized backward flow volume (p=0.001). These relationships remained significant after further adjustment for age, sex and central mean blood pressure. In a multivariate model, presence/absence of T2D and AA normalized backward flow (BF) to forward flow (FF) volumes ratio are both significant and independent correlates of EAT.ConclusionIn our study, aortic stiffness as depicted by an increased backward flow volume and decreased distensibility seems to be related to EAT volume in T2D patients. This observation should be confirmed in the future on a larger population while considering additional biomarkers specific to inflammation and using a longitudinal prospective study design.
