Urban Agroecosystems in Dynamic Yamuna River Sandbars in Delhi, Capital City of India
Authors: Das Pulak
Published: February 2024

Present paper studies urban agroecosystems on Yamuna River sandbars (islands) in Delhi using GIS. These sandbars formally come under local administration and are used by people for different activities like agriculture, fishing, collection of various types of grasses, and grazing of livestock. Cheap laborers from different states of India migrate to the sandbars for seasonal employment. The crops grown by farmers include tomatoes, pumpkins, bottle gourds, ridge gourds, and bitter gourds. Tomatoes are grown on the maximum area of land on the sandbars. The products are sold at different nearby markets according to requirements. These small and fragile agroecosystems have inputs like seeds, human labor/hours, fertilizers, water, fuels, etc., and outputs like crops, grasses, fish, milk, etc. For a long time, people have been interested in these landscapes because; i) the deposits along the Yamuna are fertile and therefore appropriate for farming, (ii) the growth of natural vegetation/fodder species (which includes many types of grasses) makes them good pastures, (iii) the river banks along the attached sandbars provide space for the washermen, (_dhobi-ghat)_, (iv) even if the government officials abandon the slums/activities on these sandbars, the people involved in them could re-build it in no time, and (v) none of the sandbar dwellers were paying any rent/lease for the activities they are carrying out on the sandbars. The pastoralists (_gujjar)_ do not seem to have to pay anything to the claimant. On the other hand, the farmers do have to pay for cultivating on the sandbars.

Published: February 2024

One indicator of good adolescent quality of life can be observed through their mental health conditions. Variables suspected to be associated with and affecting adolescent mental health include experiences of bullying. This study aims to assess the relationship between bullying experiences among adolescents and their mental health.

The research utilizes an analytical observational method with a cross-sectional design. The population consists of high school students in North Sulawesi, Indonesia, totalling 3,514 individuals. A sample of 390 students aged 15-18 years was selected using accidental sampling techniques. The relationship between bullying experiences and mental health was analysed using the chi-square test. To evaluate the extent of the risk of bullying experiences influencing adolescent mental health, multiple logistic regression analysis was employed.

The research results indicate a significant association between adolescents who have experienced bullying and their mental health (_p_ = 0.006). Adolescents who are victims of bullying are four times more likely to experience mental health disorders (OR = 4.204; 95% CI = 1.525 – 11.589). It is recommended that schools establish anti-bullying units comprising students, teachers, and parents to minimize bullying incidents in schools that can impact adolescent mental health.

The emergence of SARS-CoV-2 has led to a concerning global pandemic. The severity of COVID-19 symptoms may be enhanced due to underlying medical conditions. Several studies demonstrated severe COVID-19 infection can lead to innate and adaptive immune dysregulation, cytokine storms as well and the formation of fibromyxoid exudate in the respiratory alveolar, ultimately resulting in pulmonary fibrosis and ARDS as the leading cause of mortality and morbidity. Currently, there is a widespread global endeavor in finding efficient drugs or vaccines to manage COVID-19. Although some FDA-approved treatments have been introduced for COVID-19, alternative therapies might decrease the mortality rates. Various sources of pluripotent and mesenchymal stem cells as cell-based therapies have been applied on moderate to severe COVID-19 patients with acute respiratory distress syndrome, leading to positive results. Cell-based therapies by modulating the cytokine cascades and cellular apoptosis can probably inhibit tissue remodeling and subsequent end-organ damage. The present review aims to discuss the advantages of stem cell-based therapies in the treatment of COVID-19 patients and the possible challenges associated with their application.
Seroprevalence of Helicobacter pylori infections in children and adults in Poland in the years 2020-2023
Authors: Rastawicki Waldemar , Wiechetek-Płaza Klaudia
Published: February 2024

INTRODUCTION.
Helicobacter pylori is a common cause of gastrointestinal infections in people around the world. Various microbiological methods are used in the laboratory diagnosis of infections, including determining the presence of specific antibodies in the serum. Serological tests can also be used in epidemiological studies aimed at determining the incidence of H. pylori infections.

OBJECTIVE.
The aim of the study was to obtain insight into the incidence of antibodies to H. pylori in subjects of different ages living in Poland in the years 2020-2023.

MATERIAL AND METHODS.
The research used serum samples obtained between January 2020 and September 2023 from 600 subjects living in Poland. The Anti-Helicobacter pylori ELISA IgG enzyme immunoassay from Euroimmun was used to test the level of IgG antibodies to H. pylori antigens. Additionally, selected serum samples were tested for the presence of antibodies to the most important protein virulence factors of H. pylori by Western Blot.

RESULTS.
IgG antibodies to H. pylori, at a diagnostically significant level, were detected in 28.3% of the examined persons. Antibodies to H. pylori were least frequently detected in children under 10 years of age (12.1%) and teenagers (13.2%). In adults aged 20 to 50, these antibodies were more common (23.9% to 29.5%). Statistically, H. pylori antibodies were most often detected in subjects over 50 years of age (52.3%). There were no statistically significant differences in the frequency of antibodies to H. pylori depending on the gender of the examined persons. In most serum samples tested by Western Blot, the presence of antibodies to the CagA protein was detected (66.7%).

CONCLUSIONS.
The conducted research and analysis of literature data showed a similar percentage of serum samples with a diagnostically significant level of antibodies to H. pylori in people living in Poland as in people living in other European countries. The epidemiology of infections is also very similar, characterized by low morbidity in children and adolescents and an increase in the incidence of infections with the age of the examined persons. Importantly, compared to research conducted in our country several years ago, the percentage of positive results is much lower, which may be due to the improvement of social and living conditions and hygiene habits.

Larvisiding is one common way used to reduce mosquito density in breeding areas before metamorphosizing into adults. Despite numerous eradication efforts, the outcomes have not met expectations, leading to additional issues such as environmental pollution in urban areas. In the context of dengue hemorrhagic fever (DHF), addressing the challenge of mitigating the endemic outbreak entails formulating an effective strategy through a vector eradication approach. Therefore, this study explored the spatial pattern of DHF and estimated the potential spread of outbreaks. A geographic information system approach, with nearest neighbor analysis and kernel density estimation (KDE), was used to generate information regarding the pattern and potential for transmission of Aedes aegypti mosquitoes. The results showed that in 2019, a random pattern was observed, while in 2020, a clustered pattern of virus spread occurred. Furthermore, in terms of the potential transmission, an exposed zone of 9.73 km² was identified in 2019, and this increased to 15.72 km² in 2020. In this study, several important actions were implemented with a spatial approach, enabling the detection and polarization of events. However, the limitations included not being comprehensive in addressing the hygiene, sanitation, drainage, and population density aspects.

One type of rice that is rich in potential nutritional content is brown rice, but the production of this type of rice is still far behind compared to other types of rice. Therefore, special efforts are needed to support production, one of which is through the use of superior varieties accompanied by the fulfillment of the right nutrients, especially the Si nutrient. This research aims to determine the effect of adding nanosilica on the growth and yield of red rice. This research used a factorial randomized block design consisting of 2 factors, namely variety (consisting of two levels V1 = Pamera, V2 = Pamelen) and nanosilica concentration (consisting of five levels S0: 0 mL L-1 (control); S1: 7, 5 mL L-1; S2: 10 mL L-1; S3: 12.5 mL L-1; S4: 15 mL L-1.). The results of the research concluded that applying nanosilica colloid to the Pamera and Pamelen varieties at a concentration of 15 mL L-1 was able to increase plant length and number of tillers, as well as speeding up the flowering age of red rice. However, giving nanosilica had no effect on harvest age and yield components.

Published: February 2024

Horror film posters are often an important medium in attracting the attention of potential audiences and depicting the essence of the film. The typography in the poster plays a crucial role in conveying the message and atmosphere of the film. In many horror movie posters, the typeface often has a spooky character to create a tense atmosphere. The size and layout of the text are also important factors. Some posters choose to expose the film title in large, bold letters to capture attention, while others choose a more substantive look with smaller text to create mystery. Color also plays an important role in horror movie poster typography. The dominance of dark colors, such as black, dark red, or purple, is generally used to create a frightening atmosphere. This research uses a descriptive qualitative method with an approach to typographic principles, namely legibility, readibility, visibility and clarity. As a result of the research and analysis, it can be concluded that, on average, Indonesian horror film typography in 2022 uses decorative fonts to create an impression of mystery and is then modified with visual effects to add a visual impression of horror. Based on the theory of typographic principles, the average Indonesian horror film poster in 2022 will still pay attention to this theory and fulfill typographic rules.

The use of distribution models is a tool used to solve biological and environmental problems. Geographic data andenvironmental variables were analyzed to test the hypothesis that the distribution of Pinus chihuahuana and Pinus leiophyllawill be maintained by 2050 and 2080 in Mexico. Records of both species and environmental variables for the period 1910-2009 and Global Circulation Models (GFDL-CM3 and CNRM-CM5) were used under two RCP 4.5 and 8.5 scenariosprojected to 2050 and 2080. The MaxEnt algorithm was used. The results were evaluated and validated using AUC, partialRoc and Z-statistic tests. The contribution of each variable in the models was determined using the Jackknife test. Themodels estimated a current potential distribution area for P. chihuahuana of 81,614.8 km² and 15,105.3 km² for P. leiophylla.The relevant variables in the current period for P. chihuahuana were Bio1, Bio6, Bio13 and Bio19, while in P. leiophylla theywere Bio1, Veget and Edaf. However, for the future period they were Bio1, Bio19 and Bio13 for P. chihuahuana, and Bio1,Bio14 and Bio4 for P. leiophylla. The CNRM-CM5 and GFDL-CM3 GCM projections estimated a reduction in the rangesof both species from 2080 onwards. Conservation areas of 79,078.12 km² for P. chihuahuana and 10,517.8 km² for P.leiophylla were estimated at the end of the century. Areas suitable for the conservation of P. chihuahuana (Chihuahua andDurango) and P. leiophylla (Michoacán) in Mexico were identified and proposed.

Not including these elements in the debate turns thetransition into a sophism that will perpetuate socio-ecological conflicts in the territories.
The use of minerals in fiber-based packaging and pulp molding
Authors: GASKIN ELI , REED GREG , PRESTON JANET , BIZA PETER
Published: February 2024

Minerals are widely used in the pulp and paper industry for aiding the processing, economics, and final quality of fiber-based products. Among these, calcium carbonate, talc, and kaolin are widely used as fillers, and these can have varying brightness, particle size distributions, and aspect ratios. For the molded fiber area, these minerals can raise the solids content of the pulp mixture and improve throughput and lower energy requirements for drying. Talc is also widely used as a process control agent, picking up pitch and stickies and improving productivity by lowering machine cleaning time. The replacement of single use plastic with fiber-based replacements is a global trend; however, it does come with some significant challenges, such as grease and moisture proofing. Previously, per- and polyfluoroalkyl substances (PFAS) have been used to provide functions such as water and grease repellency, but regulatory demands have seen its demise in the packaging industry. Therefore, water holdout is now generally achieved by addition of alkyl ketene dimer (AKD) sizing. Wax additives are being developed and tested as PFAS replacements for oil and grease resistance. Rather than strongly repelling lipids from the fiber surface, these PFAS alternatives restrict flow pathways and react with food oils to alter their flow characteristics to prevent penetration through the substrate. During studies incorporating both PFAS substitutes and minerals, no detrimental interactions were observed. This paper addresses the different needs of the molded fiber market by including mineral fillers in molded fiber articles and will be presented as a series of different case studies. In all studies, we show that the trends observed when mineral filler is added to molded fiber are broadly similar to those seen in conventional paper and paperboard applications. Mineral addition in all studies gave improvements in productivity and optical appearance. With its organophilic surface, hydrophobic talc had the additional advantage of pitch and sticky control, and although a small decrease in strength was always observed when filler was added, the final articles still retained sufficient strength for their particular application. This small strength reduction should be balanced against the productivity gains.
The Adequacy of Global Legal Norms on Legal Issues Related to Digitalization and Artificial Intelligence
Authors: Alparslan Gulde
Published: February 2024

This research aims to examine the sufficiency of global legal norms on legal norms in the field of digitalization and artificial intelligence. Descriptive scanning model, content analysis methods and semiotic analysis methods were used in the research. In this context, in the research, studies on global law and artificial intelligence were analyzed and their results were evaluated. It was then analyzed with SWOT analysis in terms of artificial intelligence, global law and digitalization. According to the results obtained from the literature review and semiotic analysis, digitalization and globalization are in a two-way relationship as two important concepts that trigger each other and are primarily affected by artificial intelligence applications. Although artificial intelligence applications positively affect the digitalization process in terms of their legal effects, they also bring with them some drawbacks in judicial matters and global jurisdiction. In particular, the fact that the exact framework of the artificial intelligence issue is not yet known, that it is open to external interventions, that a global legal system has not yet been formed, and the differences between international law and regional legal systems can be listed as the most important problems in the legal applications of artificial intelligence. As a result, globalization brings developments that will necessitate important and radical changes in the field of law, as in all areas of life. Therefore, although the law has a much faster and more effective working environment than in the past, it is also open to manipulation. Current global legal norms are inadequate regarding both digitalization and artificial intelligence. In the legal field, on the one hand, cumbersome and bureaucratic legal systems must be abandoned, and on the other hand, more dynamic, more modern and faster legal systems must be adopted.

Multiple sclerosis is an inflammatory neurodegenerative disorder, and cognitive problems occur in the early and late phases of the disease. The purpose of this study was to investigate the relationship between serum glial fibrillary acidic protein and neurogranin levels and cognition in patients with multiple sclerosis (MS). Twenty-three patients and 25 healthy controls were included in the study. Serum glial fibrillary acidic protein (GFAP) and neurogranin (NRGN) levels were determined on blood samples from patients and controls. Disease duration and EDSS scores of patients were recorded, and the Montreal Cognitive Assessment (MOCA) scale was used for cognitive assessment. There was no statistically significant difference between the two groups in terms of serum NRGN and GFAP levels. MOCA scores were lower in the patient group than in the healthy control group. No statistically significant correlation was found between NRGN and GFAP serum levels and MOCA scores. Our study showed that there was no statistically significant association between serum NRGN and GFAP levels and cognition in MS patients. This study is the first to examine serum GFAP and NRGN levels in the context of cognition in MS.
