Published: January 2021

3-Aminopropyl-trimethoxysilane was introduced into bis-triazinyl amino-stilbene through the condensation reaction to obtain fluorescent whitening agents (FWAs) having excellent photo-stability. Tetraethoxysilane was hydrolyzed and combined with FWAs through in situ polymerization to obtain nanosilica-loaded yellowing inhibitors (SiO2–FWAs). Ultraviolet (UV) spectroscopy showed that the ratios of the trans-isomer structure in FWAs after 3 h of UV irradiation was 5.41 times higher than those of the cis-isomer. Moreover, the absorption intensity in the UV region was increased distinctly after nano-silica loading. Fluorescence spectroscopy revealed that the fluorescence of SiO2–FWAs was more intense than that of FWAs. In addition, the fluorescence quantum yield of SiO2–FWAs reached 0.416, whereas that of the default FWAs was only 0.279. UV-aging test results showed that SiO2–FWAs can improve the initial whiteness and anti-yellowing performance of paper made from high-yield pulp (HYP). These results indicated that the as-prepared SiO2–FWAs not only exhibited more excellent UV absorption and fluorescence emission properties, but it also exerted better whitening and anti-yellowing effects on high-yield pulp paper than the default FWAs. The enhanced performance of SiO2–FWAs can be ascribed to the synergy between the excellent UV-scattering effect of nanosilica and the fluorescent whitening property of FWAs.

Published: January 2021

The correlation between the fibre flexibility and cross-sectional area moment of inertia of thermomechanical pulp fibres was investigated. The main effects of refining were found to be internal fibrillation, external fibrillation, and fibre shortening. Internal fibrillation increases fibre flexibility and fibre collapsibility, improving fibre-to-fibre contact in a paper sheet. The raw materials used were pulps produced from six different Norway spruce logs and six different Scots pine logs, chosen in a manner that allowed variation of fibre wall thickness and fibril angle independently. Each wood sample was refined in four stages using a pressurized 12″ Sprout Waldron single disc refiner. Fibre flexibility was assessed by FiberMaster bendability measurements. Fibre bendability was measured on the +48 Bauer McNett fractions of the twelve 2nd, 3rd, and 4th stage thermomechanical pulps (TMP). The fibre cross-sectional samples were imaged using scanning electron microscopy (SEM). An image analysis method to calculate the area moment of inertia of each fibre using numerical integration was developed. Fiber bendability increased with specific energy consumption for both wood species (spruce and pine) from the 2nd refining stage to the fourth refining stage. Spruce had a higher rate of bendability increase than pine upon refining. It was expected that fibres with a low area moment of inertia would result in higher bendability, but no such correlation was found for either spruce or pine. Fibre bendability increased with internal fibrillation, as assessed from Simons staining. These results imply that local damage of the fibre wall such as delaminations, kinks, and compressions was the main effect in increasing the flexibility through refining of TMP.

Keberhasilan pembangunan di sektor pertanian suatu Negara harus tercermin oleh kemampuan Negara tersebut dalam swasembada pangan, atau paling tidak ketahanan pangan. Saat ini ketahanan pangan saja dianggap tidak cukup untukmewakili identitas Negara agraris, Namun pemerintah juga kesulitan untuk mencapai target swasembada pangan hingga akhirnya mengeluarkan beberapa kebijakan untuk mencapai hal tersebut. Salah satu kebijakannya adalah program diversifikasi pangan yang tercermin dalam Peraturan Presiden Republik Indonesia No.22 tahun 2009 yang menetapkan kebijakan percepatan penganekaragaman konsumsi pangan berbasis sumberdaya lokal. Kebijakan ini dipersiapkan untuk mengurangi permasalahan yang timbul sekarang yaitu karena hampir seluruh masyarakat Indonesia menggunakan beras sebagai makanan pokoknya. Sedangkan laju produksi beras dengan tingkat permintaan konsumen semakin tidak seimbang. Padahal, jika dilihat dari segi pemenuhannya masih banyak sumber pemenuhan kebutuhan pokok selain beras yang bisa dikembangkan. Tujuan dari penelitian ini adalah : 1) Mengidentifikasi karakteristik responden di Kota Depok. 2) Menganalisis pengaruh variabel budaya, sosial, pribadi, dan motivasi terhadap persepsi konsumsi pangan pokok non beras masyarakat di Kota Depok. 3). Menganalisis pengaruh variabel budaya, sosial, pribadi, dan motivasi secara bersama-sama terhadap persepsi konsumsi pangan pokok non beras masyarakat di Kota Depok.

Published: January 2021

Functional and metabolic features of intact and stimulated mononuclear phagocytes were studied in patients with different clinical courses of multiple sclerosis, the study included 66 patients with relapsing-remitting and 32 patients with progressive course of multiple sclerosis. The state of the mononuclear phagocytes was characterized by expression of costimulatory molecules and direction of L-arginine metabolism. Relative quantities of CD80, CD86 and PD-L1 positive monocytes were determined with Phycoerytrin-labeled monoclonal antibodies in immunofluorescence test in peripheral blood and after culture in parallel series with addition of: (a) E.coli lipopolysaccharide (a stimulator of TLR4), (b) a single-stranded RNA – preparation ssRNA40/LyoVec (a stimulator of TLR7/8), (c) IL-4 (an anti-inflammatory interleukin). The formation of NO was determined by the amount of nitrite in the culture supernatants, arginase activity was determined in cell lysates of the monocyte fraction. We showed that functional and phenotypic characteristics of monocytes depend on the clinical course of multiple sclerosis. In patients with progressive course, the relative number of CD86+ cells was significantly higher and PD-L1+ cells significantly lower than in patients with relapsing-remitting course and healthy persons, in patients with relapsing-remitting course the number of PD-L1+ cells was increased. The number of CD80+ cells did not show any significant difference in the investigated groups of patients relative to the control group. In vitro stimulation of peripheral blood monocytes with TLR4/8 produced a significant increase in the number of CD86+ and decrease in the number of PD-L1+ cells in patients with the progressive course. In patients with the relapsing-remitting course LPS produced an increase in number of PD-L1+ cells. We did not find any difference in activity of the arginase pathway of L-arginine metabolism in the intact monocyte fraction of peripheral blood in patients with multiple sclerosis versus the control group, but stimulation with TLR4 agonist of mononuclear cells of patients with progressive course caused significant increased arginase activity versus baseline. At the same time, versus control cells arginase activity in patients with the progressive course decreased after LPS treatment, but trended to increase after TLR7/8 treatment. In patients with the relapsing-remitting course these changes had a similar direction but were less expressed. The results may be considered as an indication of the activation of peripheral blood monocytes and their polarization trend in the M1 direction in patients with the progressive course of multiple sclerosis, these changes could be considered as signs of violation of autoimmune regulatory mechanisms in multiple sclerosis.
Complex impact of polarized and non-polarized low intense light and methylene blue on growth rate of some opportunistic microorganisms

Published: January 2021

Resistance to antibiotics is considered as a global and unsolved problem in the branch of medicine. That is why the use of novel non-drug methods of treatment of bacterial and fungal infections is of great relevance. One of such methods is photodynamic treatment, which is a treatment procedure that uses light energy to activate a photosensitizing agent in the presence of oxygen. Due to the broad spectrum of action, the efficacy against antibiotic resistant cells and the lack of selection of photoresistant strains, antimicrobial photodynamic therapy compares favourably with traditional drug therapy, and has emerged in the clinical field as a potential alternative to antibiotics to treat microbial infections. In this article results of studies of the complex effect of methylene blue (0.1% aqueous solution) and LED radiation of the red-infrared spectrum as well as methylene blue and polarized incoherent low-energy radiation (PILER) with a red light filter on the growth rate of some opportunistic microorganisms on solid nutrient media are presented. Standardized suspensions of microorganisms were prepared for research with the subsequent determination of direct impact of polarized and non-polarized radiation (at duration of exposure of 5 min), photosensitizer, and also the set of these factors on growth of the studied microorganisms. The growth intensity of bacteria and yeast-like fungi was determined by the number of their colonies after reseeding on nutrient media in Petri dishes. The obtained data were compared with control groups, which were not influenced by any factors. The results indicate a significant antimicrobial effect of the combined action of different types of radiation and methylene blue on microorganisms, which was manifested in a reduction in the number of colonies by on average 35–45%, compared with the control groups. Comparing the effect of exposure when using LED and PILER light, we have noted its similarity. It is also worth noting a certain antimicrobial activity of 0.1% methylene blue solution on the studied strains, but this was much less pronounced than in the complex effect. The direct effect of both LED and PILER radiation with low duration of exposure caused the stimulation of the growth of the studied microorganisms with an increase in the number of their colonies on Petri dishes by 15–35%. Given the rapid growth of resistance to antimicrobial agents, the described technique can be used as an alternative to traditional antibiotic therapy for the treatment of purulent-inflammatory diseases of the skin and mucous membranes.

Published: January 2021

Hypertension in its origin is a heterogeneous and multisystemic disease. Evaluation of oxidative stress activity based on the level of 8-iso-PgF2α, proinflammatory activity based on tumour necrosis factor-α, its type I soluble receptor, and C-reactive protein levels is relevant for further understanding of pathogenesis of hypertension and improvement of the early diagnostics of heart failure. 186 hypertensive patients were observed during a 2-months course of treatment, aged 30 to 65 years. Serum levels of 8-iso-PgF2α (n = 34), tumour necrosis factor-α and its type I soluble receptor were determined by ELISA before and after course of treatment. C-reactive protein level was determined by biochemical method. The control group included 16 clinically healthy individuals, aged 27 to 55 years. Hypertensive patients enrolled into the study were randomized into three groups that received different protocols of combined anti-hypertensive therapy: I clinical group – а combination of bisoprolol and indapamid, II – а combination of lacidipine and candesartan, III – а combination of fosinopril sodium and hydrochlorothiazide. On the background of combined antihypertensive therapy, we observed favourable dynamics of 8-iso-PgF2α, tumour necrosis factor-α and its type I soluble receptor, and C-reactive protein levels. Taking into account the insignificance of the correlations revealed, a one-factor dispersion analysis was applied which allowed us to determine the influence of the grade and duration of hypertension on the dynamics of the studied parameters. It has been found that the grade of hypertension is related to an increase in TNF-α and 8-iso-PgF2α serum levels, but not in TNF-α type I soluble receptor, and the duration of hypertension is related to an increase in C-reactive protein, TNF-α and its type I soluble receptor levels, with no relation to the level of 8-iso-PgF2α. Thus, oxidative stress possibly promotes the activation of potentially damaging immune mechanisms mediated by proinflammatory cytokines, nonspecific inflammation and drives the further progression of lesions in the target organs.
From Concrete to Bamboo: my crash course through education

Clover Hogan is a 20-year-old climate activist, researcher on turning anxiety into agency from Australia, and the founder of Force of Nature. In this article, she talks about how education is a 'system of rote, churning out worker bees for the hive' and, through education, children
are manipulated and scared into abiding by the regulatory rules. It was only when she went to Green School in Bali that she realised this, because they weren't conventional and took a more holistic approach to teaching and developing young minds by working on all three learning modalities,
using the environment surrounding them. She then decided to upturn the standardised education system and show that students aren't just only made to pass exams; they are a whole mixture of things, and it's only when a school begins to develop their understandings of nature that flexibility
in the system will happen. And those lessons make those students more equipped to be happy and to help the planet in every way [written by Lucy Gibbons on behalf of Clover Hogan].

Published: January 2021

Abstract: Public spaces could promote health equity by providing a place for people to engage in physical activity. Whereas most studies show a positive association between public spaces and physical activity, there are still mixed results, especially in low- and middle-income countries. The objectives of this mixed-methods study were: (i) to assess the quantitative association between access to public spaces and physical activity; (ii) to assess the modification of the association by public spaces quality, area-level walkability, and social stratifiers; (iii) to explain the quantitative results using qualitative data. Quantitative data were obtained with a household survey in two arid-climate Mexican cities in 2017-2018. physical activity was measured with the Global Physical Activity Questionnaire. Access to public spaces was measured in buffers centered on survey blocks, walkability with area-level indicators, and public spaces quality with the Physical Activity Resources Assessment. Qualitative data were obtained with semi-structured interviews and neighborhood observation. No quantitative association between access to public spaces and physical activity was found, as well as no interactions between access to public spaces and other variables. Walkability was positively associated with physical activity. Qualitative analysis showed that local public spaces were rarely used by adults because they were perceived as small, unequipped, unattractive, and unsafe. The results shed light on the relationship between public spaces and physical activity, highlighting the improvements in design and upkeep of public spaces that are necessary to achieve their potential health benefit.

Abstract: The aim of this study was to analyze the association between birth by cesarean section and central adiposity in adolescents in São Luís, Maranhão State, Brazil. This was a cohort study that included 601 participants evaluated at birth and at 18-19 years. At birth we assessed type of delivery, maternal education, family income, maternal marital status, maternal body mass index before pregnancy, prenatal care, maternal smoking habit, gestational age at delivery and intrauterine growth restriction. In the adolescents, we evaluated central adiposity using the dual X-ray energy absorptiometry method. The indicators of central fat used were the trunk-to-total fat mass ratio (T/T), the android-to-gynoid fat mass ratio (A/G), the trunk-to-limb fat mass ratio (T/Lb), and the trunk-to-leg fat mass ratio (T/Lg). A theoretical model for the study of associations was developed using directed acyclic graphs, which allowed selecting the variables that required minimum adjustment for inclusion in the predictive model of exposure to cesarean delivery. The data were analyzed with marginal structural models weighted by the inverse of the probability of selection. A total of 38.6% of the adolescents studied were delivered by cesarean section. There was no significant difference in the central adiposity of adolescents delivered by cesarean section according to the indicators used: T/T ( coefficient = -0.003; 95%CI: -0.013; 0.007), A/G (coefficient = 0.001; 95%CI: -0.015; 0.018); T/Lb (coefficient = -0.016; 95%CI: -0.048; 0.016); T/Lg (coefficient = 0.014; 95%CI: -0.060; 0.030). In conclusion, there was no association between cesarean section delivery and greater central adiposity in the studied adolescents.

Published: January 2021

The study contains an analysis of the essence of decentralization and its impacts on the creation of territorial communities. Scholarly views on the essence of the concept of ‘territorial community’ are presented and its features mentioned. The factors that determine the regional development of the territorial community as a subject of economic relations in the region have been identified. The legislative regulation of the process of creation and development of territorial communities is analysed and the shortcomings of the current situation are pointed out. The degree of decentralization over the period 2018–2020 is briefly analysed and a description of the methodology for assessing the viability of the created territorial communities is given. It is emphasised that the methodology of formation of affluent territorial communities is described in the 2015 Ukrainian legislation and approved by the resolution of 8 April No. 214 “The methodology of formation of affluent territorial communities”. The calculated indicators are given on the example of the Stepanivska united territorial community and its prospects of development are estimated. Recommendations for improving the conditions of formation and development of territorial communities in the conditions of decentralization in Ukraine have been developed. The empirical methodology used in the study proved to be liquid and can be applied in practice to the formation of the territorial community as a subject of local development.

Green Infrastructure and Biophilic Urbanism as Tools for Integrating Resource Efficient and Ecological Cities
Authors: Thomson Giles , Newman Peter
Published: January 2021

In recent decades, the concept of resource efficient cities has emerged as an urban planning paradigm that seeks to achieve sustainable urban environments. This focus is upon compact urban environments that optimise energy, water and waste systems to create cities that help solve climate change and other resource-based sustainability issues. In parallel, there has been a long-standing tradition of ecological approaches to the design of cities that can be traced from Howard, Geddes, McHarg and Lyle. Rather than resource efficiency, the ecological approach has focused upon the retention and repair of natural landscape features and the creation of green infrastructure (GI) to manage urban water, soil and plants in a more ecologically sensitive way. There is some conflict with the resource efficient cities and ecological cities paradigms, as one is pro-density, while the other is anti-density. This article focusses upon how to integrate the two paradigms through new biophilic urbanism (BU) tools that allow the integration of nature into dense urban areas, to supplement more traditional GI tools in less dense areas. We suggest that the theory of urban fabrics can aid with regard to which tools to use where, for the integration of GI and BU into different parts of the city to achieve both resource efficient and ecological outcomes, that optimise energy water and waste systems, and increase urban nature.
Late Jurassic foraminifera from the southern Waschberg-Ždánice Unit (Klentnice beds, Lower Austria)
Authors: Gebhardt Holger
Published: January 2021

Foraminiferal assemblages from Upper Jurassic Klentnice beds in Lower Austria are described and analysed. The early late Tithonian assemblages comprise 75 foraminiferal taxa and simple diversities reach up to 31 taxa per sample, pointing to comparatively high diversity in general. The assemblages are dominated by lenticulinid forms (Genera Astacolus, Lenticulina, Saracenaria, Vaginulinopsis). Trocholina is the most common genus and present in all samples. Other frequent genera are Marssonella and Neobulimina. Co-occurrence of epifaunal (grazing) herbivores and epi- to deep infaunal active deposit feeders points to mixed assemblages from different sources and supports the concept of turbiditic systems as prevailing sedimentary regimes in the basinal setting.

Impact of Internet Connection on Gifted Students’ Perceptions of Course Quality at an Online High School
Authors: Hawthorne Stacy
Published: January 2021

Online learning is on the rise in K-12 education and, with the lockdowns and social distancing measures implemented as a result of COVID-19, has gained increased prominence. While the demand for online learning is on the rise, many U.S. students lack adequate Internet connectivity to have a successful online learning experience. Connectivity issues, particularly when they impact audio, can cause students to tune out or even drop out of online learning. This is problematic for online schools and course providers who often have no control over the speed of a student’s home Internet connection. Online schools also have to balance student perceptions, which have been linked to their achievement. This mixed methods study examines the role of Internet connectivity on the perceptions of highly gifted students on the quality of their fully online English course on six domains: (a) appeal, (b) challenge, (c) choice, (d) meaningfulness, (e) self-efficacy, and (f) communication. In this study, highly gifted students who attended an online public school (N=19) that utilizes synchronous and asynchronous learning methods reported their perceptions on the six domains of online course quality and also their Internet downloads speed, which were used to divide them into two groups - low and high Internet download speeds. The results of the quantitative survey, a modified version of the Student Perceptions of Classroom
Quality (Gentry & Owen, 2004; Gentry & Springer, 2002), were then analyzed based on the two independent groups. No statistically significant difference was found in student perceptions on any of the six domains based on the participant’s Internet download speed. This finding may be limited based on the small sample size available for data analysis in this study. Focus groups supported the findings of the statistical analysis. A total of 12 themes emerged from the focus groups to help explain the students’ perceptions of their online courses. An additional two themes were identified as common technical issues caused by Internet connectivity in online learning and three themes related to troubleshooting technical issues. This study contributes knowledge to the fields of online education, gifted education, impact of student perceptions, and transactional distance in online learning.

The limited performance of pure glassy and rubbery polymeric membranes for natural gas purification are due to their intrinsic properties. Optimizing their properties by blending both polymers are expected to address the shortage. The foremost objective of this research is to synthesis enhance polymer blend membranes (EPBM) using glassy polysulfone (PSU) and rubbery polyvinyl acetate (PVAc) with the addition of amine for carbon dioxide (CO2) removal from methane (CH4). The EPBM were developed by varying the composition of PVAc ranging from 5 to 20 wt. % with 95 to 80 wt. % base PSU in dimethylacetamide (DMAc) solvent. The amines composition was added to the blend and kept at 10 wt. % over solvent. The findings showed good miscibility between PSU and PVAc blends and the original functional groups of polymers and amines were shown by FTIR with very few spectral peak shifts. The synthesized EPBM were found to have homogenous surfaces and a packed bed sphere structure as shown by FESEM images. Increasing the composition of PVAc from 5 to 20 wt. % has significantly reduced the glass transition temperature (Tg) of PSU from 185.09oC to 155.75oC.

A 25 years old male patient with osteogenesis imperfecta presented with bilateral profound hearing loss, not benefitted with hearing aid. Cochlear implantation of 12 channel intracochlear implant was done successfully, intracochlear insertion of the 12 electrodes resulted in hearing improvement of 80 dB at frequency 250 Hz to 4 KHz. The patient complained of facial twitching on first visit after switching on speech processer device, reducing the current level at the electrode 6 abolished the non-acoustic nerve excitation with preservation of acoustic performances. Osteogenesis imperfecta patient may involve a risk for non-acoustic nerve activation in cochlear implant patients possibly resulting from a decrease impedance to current spread, it happens because of abnormal bone tissue. Non acoustic nerve activation can be overcome by modification in mapping.

Background: Thalassemia is a chronic disease requiring lifelong treatment. The adherence to regular iron chelation therapy is important to ensure complication-free survival and good quality of life. The study aim to assess the adherence to iron chelation therapy (ICT) in patients with transfusion-dependent thalassemia (TDT), evaluate various causes of non-adherence and study the impact of non-adherence on the prevalence of complications secondary to iron overload.
Materials and Methods: Patients with TDT on ICT for > 6 months were enrolled in the study. Hospital records were reviewed for demographic details, iron overload status, treatment details, and the prevalence of complications. A study questionnaire was used to collect information on adherence to ICT, knowledge of patients, and the possible reasons for non-adherence.
Results: A total of 215 patients with a mean age of 15.07+7.68 years and an M: F ratio of 2.2:1 were included in the study. Non-adherence to ICT was found in 10.7% of patients. Serum ferritin levels were significantly higher in the non-adherent group (3129.8+1573.2 µg/l) than the adherent population (2013.1+1277.1 µg/l). Cardiac as well as severe liver iron overload was higher in the non-adherent patients. No correlation was found between disease knowledge and adherence to ICT. Difficulties in drug administration and many medicines to be taken daily were statistically significant reasons for non-adherence. There was no difference in the co-morbidities arising due to the iron overload in the two groups.
Conclusion: Nearly 11% of patients with TDT were non-adherent to ICT. Non-adherence results in higher iron overload.
