Published: June 2024

The increasing investigation into environmental contamination by Giardia spp. cysts and its impact on public health has spurred interest in developing more sensitive methods for detecting these protozoa, particularly in water. However, these methods remain complex and costly. This study evaluated the concentration and removal efficiency of Giardia duodenalis cysts using an acrylamide-based anionic flocculant polymer (AFP) in filter backwash water samples from a water treatment plant (WTP) located in Blumenau City, southern Brazil, and compared them with the calcium carbonate flocculation technique (CCF), which is routinely used for water matrices with high turbidity. The average recovery rates of G. duodenalis cysts using CCF and AFP were 33.33% and 43.33%, respectively, with an average turbidity reduction of 98.39% and 98.78%. The use of an anionic flocculant polymer proved to be an efficient alternative for the concentration and removal of protozoan cysts in water samples with high turbidity. It is important to highlight that the development and application of new studies and strategies aimed at increasing the efficiency of the removal of these organisms from complex environmental matrices would bring benefits to public health and promote a One Health perspective.

Published: June 2024

In this work, ytterbium (Yb) doped Bi2WO66 composite (Yb/ Bi2WO6) was prepared using a one-step hydrothermal method. The investigation focused on the photocatalytic degradation effect of Yb/Bi2WO6 on ofloxacin in water, with experimental conditions carefully controlled. The results revealed that under various conditions, Yb/Bi2WO6 exhibited excellent photocatalytic degradation performance for ofloxacin, achieving a degradation rate of 98.74% within 180 min and 93.27% after 4 cycles. These findings demonstrated that Yb/Bi2WO6 possessed good photocatalytic performance and cycling stability. The characterization results highlighted that the doping of Yb altered the morphology of Bi2WO6, narrowed the band gap, reduced photogenerated electron-hole recombination, and enhanced the photocatalytic performance of Yb/Bi2WO6. The free radical quenching experiments showed that superoxide radicals (･O2-) played a crucial role in the photocatalytic degradation of ofloxacin by Yb/Bi2WO6. Overall, this work provides new insights and theoretical support for the photocatalytic degradation of antibiotics using modified bismuth-based materials doped with rare earth elements.

Authors: Schumacher Russ , Bolinger Rebecca , Lukas Jeffrey
Published: June 2024

The official climate divisions for the contiguous United States are used for a wide range of purposes, including ongoing climate monitoring, and through NOAA’s long-standing nClimDiv dataset. In Colorado, the climate divisions are based around the basins of the large rivers that flow out of the state. However, considering the complex topography and climate of the state, these divisions do not always represent key climate variations and changes. This study builds upon an approach first developed by Wolter and Allured to establish alternate climate divisions that more closely reflect observed climate variability across Colorado. Hierarchical cluster analysis is applied to gridded temperature and precipitation data (NOAA’s nClimGrid) from 1950-2021 to identify areas with similar climate variability, then manual inspection is used to establish 11 divisions. These resulting divisions are being used in an updated state-level climate change assessment. The method is flexible and uses open-source tools that could be extended to other regions or datasets.
Tailoring interactions for cisPro peptide bond stabilization
Authors: Banerjee Shreya , Prabhakaran Erode N
Published: June 2024

Elucidation of the nature of non-covalent interactions that govern the rate-limiting cis-trans isomerism at Xaa-Pro peptide bonds is fundamental to unravelling the protein folding mechanism, the stereoelectronic control elements of the structure and dynamics of the peptide bond, and the design of novel peptide isosteres. CisPro rotamers are stabilized by very few interactions compared to the transPro rotamer and are hence relatively scarcely populated. Design of novel interactions that can bias cisPro stability, with least mutations to the prolyl peptide bond, is crucial for accessing the cisPro motif in a variety of peptides. This mini review discusses the various interactions tailored for improving cisPro stability.

This article is oriented to the degradation of nickel in an ionic state at laboratory level from synthetic water made with nickel sulfate, using the electrocoagulation process with aluminum cathodes and modifying this process by the addition of the Fenton reagent, which results from the combination of hydrogen peroxide (H2O2) and ferrous sulfate (FeSO4) being this reagent a catalyst and oxo-coagulant agent, The efficiency of this reagent will be compared with the typical treatment with aluminum sulfate, which is a typical process based on ion exchange/coagulation at the same percentage concentrations as the Fenton reagent. For this purpose, the optimum conditions of the advanced electrocoagulation process were determined, which consisted of determining the concentrations of Fenton’s reagent at concentrations of 150 ppm, 300 ppm, and 450 ppm, in addition to the operating variables such as pH of 8 and 10, voltage of 17.5 V and 19 V and their reaction time, which were compared with aluminum sulfate at 300 ppm, 600 ppm, and 900 ppm. The results obtained with respect to the typical treatment were 0% nickel degradation. However, with the advanced oxidation treatment, an average reduction of 97.5% was found at the conditions of 19 V, pH 10, and Fenton 150 ppm in a time of 30 min.

Published: June 2024

Various wastes can be utilized to produce activated carbon, one of the wastes that can be utilized is nutmeg shell (Myristica fragrans). Activated carbon from nutmeg shells (Myristica fragrans) was used in this study to reduce the content of Pb(II) and Cu(II) ions in liquid waste. This research utilized the adsorption method with the batch system to determine the optimum contact time, optimum pH, and adsorption capacity. The characterization of activated carbon was done by Scanning Electron Microscopy (SEM) and Surface Area Analyzers (SAA). The content of Pb(II) and Cu(II) ions in the filtrate after adsorption was analyzed using an atomic absorption spectrophotometer (AAS). The results of SEM analysis showed that the carbon surface was cleaner and had more open pores after the activation process than before activation. The carbon surface area is 19.6243 m2.g-1. From the results of AAS analysis, the optimum time and pH for Pb(II) and Cu(II) ions was 40 min at pH 5 and 70 min at pH 4. With the Freundlich isotherm method, the adsorption capacity of the adsorbent for Pb(II) ions was 9.6028 mg.g-1 and Cu(II) ions was 0.035 mg.g-1, and the adsorption effectiveness on liquid waste for Pb and Cu metals was 1.9454 mg.g-1 and 0.4251 mg.g-1, respectively. The results showed that activated carbon from the nutmeg shell (Myristica fragrans) was able to reduce the levels of Pb(II) and Cu(II) ions in liquid waste.
Alleviation of Different Climatic Conditions by Foliar Application of Salicylic Acid and Sodium Nitroprusside and Their Interactive Effects on Pigments and Sugar Content of Maize Under Different Sowing Dates
Authors: Devi Priyanka , Kumar Prasann
Published: June 2024

The agricultural sector is seriously impacted by climate change, leading to potential risks to food security. In terms of global food production, maize ranks third. As a result, crop production and food security depend critically on assessing the effects of climate change and developing measures to adapt maize. Regarding adaptability, changing planting dates and using different agrochemicals are more effective than other management. Crop models are part of a global decision support system to help farmers maximize yields despite unpredictable weather patterns. To mitigate yield loss and protect the ecosystem, it is essential to use efficient maize-sowing practices in the field. This experiment was carried out to identify the most favorable sowing dates that maximize yield while ensuring the crop’s productivity and the integrity of the surrounding ecosystem remain intact. The main aim of this experiment was to mitigate the different climatic conditions by exogenous application of salicylic acid (SA) and sodium nitroprusside (SNP) on pigments and sugar content in maize under different sowing dates. A field experiment was carried out in the School of Agriculture, Lovely Professional University, Punjab, India, during the spring season of 2022. The experiment dealt with various maize crops, PMH-10, sourced from the Punjab Agricultural University (PAU), Punjab. The experiment was conducted in an open-air environment. The experimental setup was laid out in a split-plot design. The results stated that foliar application of salicylic acid and sodium nitroprusside successfully influenced high-temperature tolerance and low temperature at the reproductive phase and initial vegetative stages with other growing climatic conditions of maize in early and late sowings when controlled by increasing the chlorophyll index, carotenoids content, and sugar content of maize.

Studies have emphasized that the presence of heavy metals in freshwater fish represents a global public health issue. Nigeria, being a developing nation with less emphasis on the quality of seafood consumed by the residents, ranks this study very vital. The policy implication of this study is the advancement of a healthy population in contemporary Nigeria. Hence, this study assessed heavy metal concentration in two fish species, Clarias gariepinus (Catfish) and Oreochromis niloticus (Nile Tilapia), in the Anambra River. The sample included twenty fishes, of which eighteen were collected from the three sampling locations (the fish ports of Anambra River), namely Otu-nsugbe, Otuocha, and Ikemivite) while two control samples were collected from a pond about 200 m away from the river. The levels of heavy metals were determined using Varian AA 240 atomic absorption spectrophotometer (AAS). The results showed that the concentrations of heavy metals (cadmium and arsenic) in the sampled fishes from Anambra River exceeded the joint World Health Organization and Food and Agriculture Organization (FAO/WHO) standard for fish and fish product consumption, while the concentration of chromium, mercury, and lead are within the permissible limit. The study also showed the distribution of the heavy metals in the fish organ varies among fish species. Heavy metals occur higher in Clarias garepinus than in Oreochromis niloticus, while tissue preference for heavy metal accumulation is in the order of gill > liver > muscle. It was recorded from this study that the heavy metal concentration in the fish from the pond is generally higher than the fish from the river for some metals. The high level of heavy metals in the sampled fish was attributed to heavy metals contamination of the river as a result of various anthropogenic activities such as mining, burning of fossil fuel and emission from the exhaust of boats/vehicles, overuse of fertilizers and pesticides, discharge of effluent, sewage, and hospital waste. This study concluded that long-term consumption of fish from the river may pose health risks to the consumers due to the possible bioaccumulation of heavy metals, especially cadmium and arsenic. It was recommended that continuous monitoring of heavy metal levels in the fish and water, public awareness, and appropriate legislative provisions should be put in place to ensure that harvested fish and fish products may be safe for human consumption.

Legal Certainity of The Probationary Period Regulation For Employees of Regional Water Company
Authors: Ratnawati  , Abdul Rachmad Budiono  , Hamidi Masykur
Published: June 2024

The legal conflict regarding the probationary period between the Employment Law and the Ministry of Home Affairs Regulation concerns the regulation of the probationary period, where the Employment Law stipulates that the probationary period should not exceed 3 (three) months. However, the Ministry of Home Affairs Regulation states a minimum of 3 months and a maximum of 6 months for the probationary period. Based on this, the research question of this paper is formulated as follows: What are the provisions of the Probationary Period in Article 33 Paragraph (2) of the Minister of Home Affairs Regulation on the Organization and Personnel of Regional Drinking Water Companies in terms of the Principle of Legal Certainty? The writing of this paper uses a normative juridical method with the Statue Approach and Analytical Approach. In analysing this research, several theories are employed, including the theory of legal certainty, the theory of norm hierarchy, and the theory of norm conflict. The researcher obtains answers to the existing problems by analysing the legal certainty of the probationary period regulation. In terms of the theory of legal certainty by Jan Michiel Otto, it aligns with Lord Lyod's opinion on the meaning of legal certainty, which is consistent, stable, and clear. The regulation in Article 33 Paragraph (2) of the Ministry of Home Affairs Regulation does not meet the principle of legal certainty. While the regulation in the Ministry of Home Affairs Regulation in Article 33 Paragraph (2) is consistent and clear, it lacks consistency. This is because the regulation should comply with labour laws where the maximum probationary period is 3 months, while in the Ministry of Home Affairs Regulation, the probationary period is a minimum of 3 months and a maximum of 6 months.
A study on the initial impact of the news of the discovery of X-rays in Spanish society
Authors: Gómez-Sellés Javier
Published: June 2024

The news of the discovery of X-rays spread rapidly throughout Europe, including Spain. In Spain, the news surpassed the academic field, becoming popular through different channels, mainly through the shocking image of the skeleton of a hand. X rays captured the attention of writers and thinkers; they influenced journalism and language; they appeared in advertisements associated with both medical cabinets and miracle products; But, above all, X rays became a metaphor for science as an illuminator of the shadows that accompany the human being. The impressive impact that X-rays discovery had on society at the end of the 19th century has been studied by different authors in the United States, Germany, or France. So far, however, it seems that there has been little discussion about which effects had this fact on Spanish society. Therefore, this paper is aimed to reproduce the diffusion and initial influence of the news of the discovery of X-rays in Spanish society at the end of the 19th century, beyond the scientific, medical, or purely academic field, in order to help to reconstruct the birth process of the use of ionizing radiation in Spain, concluding that it had a similar impact to that of the neighboring countries.

DIGITAL DIPLOMACY: THE INFLUENCE OF DIGITAL PLATFORMS ON GLOBAL DIPLOMACY AND FOREIGN POLICY
Authors: Barman Shanta
Published: June 2024

The Internet, digital tools, and other information and communications technology (ICTs) are supporting diplomatic efforts more and more. Diplomats use the Internet for information retrieval, email correspondence with colleagues, electronic draft text negotiation, and a growing number of new social networking sites like Facebook and blogs. In times of crisis, leaders are using hash tags to spread data and analysis and to promote government activities. Without a doubt, digital technology has influenced how the modern world operates, even to the point where it has given rise to a brand-new type of diplomacy called "digital diplomacy." This essay investigates how conventional diplomatic methods have evolved into a new era defined by digital diplomacy and assesses how this has affected international relations. It explores the various ways that digital instruments, such as online forums, virtual summits, and social media platforms, have shaped international relations. The present study delves into the notion of digital diplomacy, emphasising the application of digital media in the diplomatic sphere and the manner in which nations, particularly India, are employing these instruments to advance their foreign policies. The study examines the challenges and opportunities posed by digital diplomacy, considering issues of cybersecurity, information warfare, and the democratization of diplomacy through increased public engagement. Moreover, it investigates the implications of this digital shift on the effectiveness, transparency, and inclusivity of foreign policy frameworks. By analyzing case studies and scholarly works, this paper aims to provide insights into the intricate interplay between technology, diplomacy, and foreign policy in an era dominated by digital connectivity.
Mustafa Sabri Efendi’nin Nüzûl-i Îsâ Meselesinde Sünnetin Kaynaklığına Başvurma Yöntemi
Authors: Yıldırım Esra
Published: June 2024

Mustafa Sabri Efendi, Osmanlı Devleti’nin siyasi kayıplar yaşadığı dönemin sonlarında Şeyhülislamlık yapmış, Cumhuriyet’in ilanı sürecinde yaşamıştır. Batı’daki bilimsel gelişmelerle birlikte İslam düşüncesinde duraklamanın tecrübe edildiği dönemde, geleneksel ilmî mirası ve bu ilimlerin metotlarını savunmuş bir isimdir. Bu hassasiyetle modern bilimsel yöntemleri savunan çoğu İslam düşünürüne eleştiriler yöneltmiştir. O, bu dönemde düşünce akımlarının etkisiyle gelişen inanç problemleri karşısında geleneksel yöntem ve bilgi birikiminin etkinliğini gündeme getirmiştir. Mustafa Sabri, İslam’ın temel kaynaklarından biri olan sünnet ve bunun kayıt altına alındığı rivayetleri içeren muteber hadis kaynaklarının metot ve sıhhat açısından son derece güvenilir olduğunu ve itikadî konularda belirleyici olduğunu vurgulamıştır. Mustafa Sabri’nin sünnet tasavvurunu göstermesi açısından onun nüzûl-i Îsâ konusundaki görüşleri önemli bir örnektir. O, nüzûl-i Îsâ hadisesi hakkındaki yaklaşımını, Mahmut Şeltut’a yönelik itirazlarıyla ortaya koymaktadır. O, bu hadisenin Hz. Peygamber’in gayba ilişkin verdiği haberlerden biri olması ve kıyamet alametlerinden sayılması noktasında, sünnetin kaynaklığını öne çıkarmaktadır. Nüzûl-i Îsâ’nın gerçekleşme imkânını günümüzde sıhhati açısından problemli kabul edilen rivayetler, sahabe, tabiûn ve sonraki İslam âlimlerinin ortaya koyduğu yaklaşım ve hadis kaynaklarına duyduğu itimat üzerinden inşa etmektedir. Mustafa Sabri bu anlamda geleneksel birikimi öne çıkaran bir sünnet tasavvuru ortaya koymaktadır. Bu kapsamda çalışmamız Mustafa Sabri’nin nüzûl-i Îsâ çerçevesinde sünnetin kaynaklığına ilişkin yaklaşımını ele almayı amaçlamaktadır.

Bu çalışmada dönen patlama motorundaki patlama dalgası yapısı ve itki performansı sayısal olarak incelenmiştir. Sayısal çalışmalar iki aşamada gerçekleştirilmiştir. İlk olarak deneysel ve sayısal verilerin yer aldığı referans çalışmaya yönelik doğrulama çalışmaları tamamlanmıştır. Deneysel çalışmalarda hidrojen 0.8 mm çapındaki 90 enjektörden, hava ise 0.4 mm genişliğindeki aralıktan patlama kanalına aktarılmaktadır. Referans sayısal çalışmada yer verildiği üzere tek basamaklı tersinmez hidrojen-hava mekanizması doğrulama çalışmalarında kullanılmıştır. Doğrulama analizleri sonrasında patlama dalgasının detaylı olarak incelenebilmesi için 19 basamaklı tersinmez hidrojen-hava reaksiyon mekanizması sayısal çalışmalara tanımlanmıştır. Sayısal çalışmalarda daimi olmayan yoğunluğa dayalı çözücü kullanılmıştır. İkinci aşamada patlama dalga yapısı ve dönen patlama motorunun itki performansı araştırılmıştır. Sonuç olarak patlama dalgasının 1.1 ms sonrasında kararlı yapıya ulaşabildiği belirlenmiştir. Değişen blokaj oranı nedeniyle t=1.1 ms öncesinde patlama dalgası yüksekliği sabit kalmamıştır. Kararlı patlama dalgası yüksekliğinin tek basamaklı ve 19 basamaklı çalışmalarında sırasıyla 29 mm ve 27 mm olduğu tespit edilmiştir. Patlama kanalı çıkışındaki itki dağılımının kararlı patlama dalgası ile neredeyse sabit olduğu belirlenmiş ve itki değerinde 678.7±2.3 N aralığında salınımların meydana geldiği gözlemlenmiştir.

Published: June 2024

In hydrogen-oxygen fuel cells, operating parameters have an influence on the maximum expected open circuit (Nernst) voltage. Even though fuel cells have been the subject of many research, none of them have theoretically investigated the impact of various operating parameters, particularly concerning Nernst voltage and maximum thermodynamic efficiency. In this study, a computer program was developed to theoretically determine the effect of various operating parameters on the Nernst voltage in hydrogen-oxygen fuel cells. This computer program was developed in MATLAB to mathematically examine the effects of hydrogen and oxygen mole ratios, anode and cathode pressures, and operating temperatures on the maximum expected open circuit voltage. When calculating Nernst voltages and maximum thermodynamic efficiency for fuel cell reactions containing water as a by-product, the effects of higher heating value (HHV) and lower heating value (LHV) are also considered in the solutions. As a result, it was also concluded that temperature increase reduces the fuel cell Nernst voltage and maximum thermodynamic efficiency. Therefore, it was observed from the figures that the best conditions for the Nernst voltage occur when HHV is assumed, the temperature is 353 K, the mole ratios of hydrogen and oxygen are 1.0, the anode and cathode pressures are 5 atm and 6 atm, respectively. In terms of thermodynamic efficiency, it was determined that there was a maximum increase of 92.2% in the LHV assumption compared to the HHV assumption at the temperature of 1000 K, provided that other operating parameters were kept constant.

Outdoor tests of photovoltaics module are crucial both for marketing and for research and technological developments. The electric generation performance and their degradation rates and lifetime are also related to different climatic conditions of the regions. In this work, the outdoor tests are carried out for six different photovoltaic (PV) modules under Arid-steppe Climate condition of Ankara, Türkiye. Their degradation rates are calculated by using linear regression (LR) and year on year (YOY) methods. The comparison between LR and YOY are carried out and with the other performed studies of different regions of world. In addition, it is investigated that how effective the climatic conditions on daily degradation rates. The results obtained are as follows: Mono-Si and Hetero-junction Silicon (HIT) cell modules degradation rates of 0.71/1.56 %/year and 0.84 %/year are respectively obtained by LR method and 0.57/0.90 %/year and 0.85%/year are respectively by YOY method. The degradation rates for Cupper Indium Selenide (CIS), Cupper Indium Gallium Selenide (CIGS) and microcrystalline Silicon/Amorphous Silicon (µc-Si/a-Si) modules have 1.73/1.49 %/year, 11.55/9.52 %/year and 1.48 %/year for LR method and 1.28/1.12 %/year, 9.94/9.53 %/year and 0.99 %/year for YOY method are obtained respectively. It is also obtained for the Polycrystalline Silicon Modules as 1.20/1.86 %/year degradation rates by LR method and 0.79/1.88 %/year degradation rates by YOY method.

Published: June 2024

The performance of high-lumen light-emitting diode (LED) arrays is strongly affected by high temperatures. For better performance, the design of better thermal management techniques is required. In this work, an analytical thermal optimization algorithm for the passive heat sinks of high-lumen LED arrays is presented. With the aid of this algorithm, a broader range of heat sink geometry alternatives can be explored for the identification of the optimal heat sink design. This task is challenging using experimental or numerical techniques. The results demonstrate that the algorithm yields design with a reduction of more than 30% in base temperatures compared to previous heat sink design studies when minimum mass and maximum total efficiency constraints are applied. For devices with high powers, small chip spacing, and space limitations in the horizontal axis where base temperatures cannot be further reduced using these constraints, minimum temperature optimization can result in up to a 17% reduction in base temperatures. This reduction in base temperatures significantly improves the junction temperatures and the overall lighting quality of the LEDs.
