Authors: Subramaniam Ponnusamy , Arulkumar Muthusamy , Helan Soundra Rani Michael , Nazneen Bobby Mohammed , Wesely Edward Gnanaraj
Published: March 2024

Aim of the study is to determine the anti-inflammatory, antidiabetic (α-amylase activity) and radical scavenging potentials of both leaf and stem ethanolic extracts of Entada rheedii and Myristica beddomei. DPPH, ABTS, H2O2, superoxide, hydroxyl and nitric oxide activity relate to inhibition ratio with different concentrations of extracts (μg/mL). Antidiabetic (α-amylase activity) and anti-inflammatory activities were also analyzed which showed high radical scavenging activity in a dose depending manner. Comparatively, leaves and stems of Entada rheedii showed higher radical scavenging activities compared to Myristica beddomei. Furthermore, both leaves and stem of Entada rheedii showed appreciable α-amylase inhibitory effects when compared with acarbose (standard drug) and also possess a strong anti-inflammatory effect (Diclofenac sodium, standard drug), compared to Myristica beddomei extracts. Overall, our results established the key evidence for Entada rheedii and Myristica beddomei extracts to be considered as a natural therapeutic aliment as the substitution for oxidative stress.

The use of fertilizers is a common practice to improve soil fertility and increase crop yields. Chemical fertilizers have played a significant role in increasing crop yields, but their widespread use has led to environmental degradation and soil depletion. The continuing challenges in agro-ecosystem and environment require more sustainable solutions than chemical fertilizers. In recent years, there has been a growing interest in the use of biofertilizers as a sustainable alternative to chemical fertilizers. Biofertilizers are natural substances that improve soil fertility, modify soil microbiota and enhance plant growth. Cyanobacteria are one of the well-known bio inoculants for paddy crops. However, the use of cyanobacteria for other plants has not been very well documented. We screened certain cyanobacteria isolated from different natural environments as biofertilizers for certain aromatic plants. Artemisia pallens and Origanum majorana are two plants with aromatic compound productions. The aim of this study was to screen for enhancement in the growth and propagation of the plants for their yield using bio inoculants. Further air-dried, powdered plant materials of the aerial parts of A pallens and O. majorana were extracted using solvents ranging in polarity from non-polar (n-hexane), semi-polar (chloroform) and polar (acetone, methanol). These extracts were tested for antioxidant activity, several plant extracts showed antioxidant activity, with water exhibiting the greatest levels. The purpose of the experiment was to investigate the effects of bioinoculants on the growth of the test plant. Our observation showed that all the tested cyanobacterial strains i.e. KM1, KM2 and VM1, VM2, the bioinoculants, enhanced plant growth to various levels. KM1 and KM2 exhibited a greater ability to increase plant growth. This demonstrates that Artemisia's and Origanum’s growth and herbage output may be successfully enhanced by the use of cyanobacterial bioinoculants.

The article is dedicated to the world famous Russian bass singer Nikolai Petrovich Okhotnikov. The singer performed leading roles in more than thirty works by Russian, Italian, French and German classics of world opera. Okhotnikov’s repertoire is largely marked by an original interpretation of dramatic images, through which he was able to achieve signifi cant heights in the art of opera. Based on the traditions of the Russian vocal school, instilled in Okhotnikov by his teacher Ivan Ivanovich Pleshakov, the singer became famous for the rich timbre of his voice, the highest skill in acting, and the depth of psychological penetration into the role. Okhotnikov was also widely known as a vocal teacher who trained many talented singers that continued the direction of their teacher.
pKalculator: A pKa predictor for C-H bonds
Authors: Borup Rasmus M. , Ree Nicolai , Jensen Jan
Published: March 2024

Determining the pKa values of various C-H sites in organic molecules offers valuable insights for synthetic chemists in predicting reaction sites. As molecular complexity increases, this task becomes more challenging. This paper introduces pKalculator, a quantum chemical (QM)-based workflow for automatic computations of C-H pKa values, which is used to generate a training dataset for a machine learning model (ML). The QM workflow is benchmarked against 695 experimentally determined C-H pKa values. The ML model is trained on a diverse dataset of 775 molecules with 3910 C-H sites. Our ML model predicts C-H pKa values with a mean absolute error (MAE) and a root mean squared error (RMSE) of 1.24 and 2.15 pKa units, respectively. Furthermore, we employ our model on 1043 pKa-dependent reactions (Aldol, Claisen, and Michael) and successfully indicate the reaction sites with a Matthew’s correlation coefficient (MCC) of 0.82.

Protein protected metal nanoclusters (NCs) represent a new class of highly photoluminescent nanomaterials that have wide applications. Suitable reaction conditions combining protein and metal precursors can produce a vast range of different NC sizes. The number of metal atoms per protein can be determined by mass spectrometry (MS). MS coupled with matrix-assisted laser desorption ionization (MALDI) presents a number of advantages such as detection with high sensitivity of nanoclusters with high molecular weights. Although many protein-protected metal nanoclusters have been characterized by MALDI-MS, a large dispersion in the number of metal atoms have been reported mainly due to sample preparation. In this work, we optimized the protocols for negative and positive ion detection mode as a general MALDI-MS sample preparation method for protein protected metal nanoclusters (bovine serum albumin and lysozyme and with gold and silver). Negative and positive ion mode detection was compared, showing that negative ion mode detection in MALDI-MS can also be used with acidic matrices. Obvious matrix effects on ion signals and peak positions by MALDI-MS was observed. The metal atom number of metal nanoclusters embedded in proteins is different depending on the MALDI matrix most probably due to fragmentation. The matrix effects give a warning for more serious consideration on MALDI-MS measurement and spectra analysis of nanoclusters.

Oxalate ligands are found in many classes of materials, including energy-storage materials and biominerals like hydrated calcium-oxalates. Determining their local environments at the atomic scale is thus paramount to establishing the structure and properties of numerous phases. Here, we show that high-resolution 17O solid-state NMR is a valuable asset for investigating the structure of crystalline oxalate systems. First, an efficient 17O-enrichment procedure of oxalate ligands is demonstrated using mechanochemical saponification. Then, the use of 17O-enriched oxalates for the synthesis of the biologically relevant calcium-oxalate monohydrate (COM) phase is presented, enabling the analysis of its structure and heat-induced phase transitions by high-resolution 17O solid-state NMR. NMR studies of the low-temperature COM form (LT-COM), using magnetic fields varying from 9.4 to 35.2 T, as well as 13C-17O MQ/D-RINEPT and 17O{1H} MQ/REDOR experiments, enabled the 8 inequivalent oxygen sites of the oxalate ligands to be resolved, with a tentative assignment proposed. Then, the structural changes occurring upon heat treatment of COM were followed by high-resolution 17O solid-state NMR, providing new insight into the structures of the high-temperature form (HT-COM) and anhydrous calcium oxalate alpha-phase (alpha-COA), including the presence of structural disorder in the latter case. Overall, this work highlights the ease associated with 17O-isotopic enrichment of oxalate oxygens, and how it enables the study of oxalate structures (including materials of biological relevance) at high-resolution via solid-state NMR, in the frame of “NMR-crystallography” investigations.
Three-way data reduction based on essential information
Authors: Vitale Raffaele , Azizi Azar , Ghaffari Mahdiyeh , Omidikia Nematollah , Ruckebusch Cyril
Published: March 2024

In this article, the idea of essential information-based compression is extended to trilinear datasets. This basically boils down to identifying and labelling the essential rows (ERs), columns (ECs) and tubes (ETs) of such three-dimensional datasets that allow by themselves to reconstruct in a linear way the entire space of the original measurements. ERs, ECs and ETs can be determined by exploiting convex geometry computational approaches such as convex hull or convex polytope estimations and can be used to generate a reduced version of the data at hand. These compressed data and their uncompressed counterpart share the same multilinear properties and their factorisation (carried out by means of, e.g., Parallel Factor Analysis-Alternating Least Squares - PARAFAC-ALS) yield, in principle, indistinguishable results. More in detail, an algorithm for the assessment and extraction of the essential information encoded in trilinear data structures is here proposed. Its performance was evaluated in both real-world and simulated scenarios which permitted to highlight the benefits that this novel data reduction strategy can bring in domains like multiway fluorescence spectroscopy and imaging.
Electrocatalytic hydrogen evolution performance of mesoporous Ni/NiO/carbon composites fabricated from carbon dots
Authors: Yang Yan , Liu Ruihan , Liu Weiruo , Ji Lexuan , Gao Mengjie , Zhai Yunpu
Published: March 2024

Mesoporous Ni/NiO/carbon composites were successfully prepared from the tri-component self-assembly of carbon dots, nickel precursors and surfactant F127. The functional groups of carbon dots can chelate with the metal and then further assemble with the surfactant to prepare mesoporous metals/carbon materials (Ni-NC/MC), which are applied to the electrolysis of water to produce hydrogen. The results show that the interaction between Ni/NiO heterostructures is the active component of the catalyst. The carbon dots show a certain confinement effect, which hinders the further growth of metal particles. Moreover, large specific surface area and suitable Ni/NiO ratio are beneficial to the HER catalytic activity and operational stability of the catalyst.
Schyłek dyscyplin: zmagania w polu czy o pole socjologii?
Authors: Woroniecka Grażyna
Published: March 2024

W artykule przedstawiam próbę analizy aktualnej sytuacji socjologii w kontekście cech dystynktywnych dyscypliny, porównując cztery plany jej funkcjonowania: plan edukacyjny, plan badawczy, plan awansów zawodowych oraz plan administracyjno-prawny. W planie edukacyjnym prezentuję skutki procesu bolońskiego oraz rywalizacji o oferty edukacyjne między uniwersytetami i wydziałami. W planie badawczym skupiam się na koncepcji episteme klasycystycznej (Foucault), z której wyłoniły się dyscypliny (taksonomia), oraz na późnomodernistycznym horyzoncie „wypływania” nauk z ram akademii i dyscyplin. W planie awansów zawodowych ilustruję starania środowiska o uprawomocnienie prac inter- i transdyscyplinarnych wraz z towarzyszącymi temu ambiwalencjami. I na koniec, w planie administracyjno- prawnym, interpretuję zapis ustawowy mówiący o możliwości uzyskania doktoratu z dziedziny nauki, a nie z dyscypliny naukowej. Materiał badawczy, na którym opieram przedstawiane wnioski, pochodzi z dwóch źródeł: z kilkunastoletnich studiów etnometodologiczno-hermeneutycznych nad recenzjami prac doktorskich i habilitacyjnych oraz z 22 lat doświadczeń członkini rad naukowych nadających stopnie naukowe.
Czy przemoc domowa ma płeć?
Authors: Grzymała Justyna
Published: March 2024

Artykuł poświęcony analizie roli płci ukazuje toczącą się w środowisku naukowym debatę między przedstawiciel(k)ami dwóch podejść: perspektywy symetryzmu płci oraz perspektywy feministycznej. Odmienne znaczenie przypisywane płci przełożyło się na inny sposób prowadzenia badań, co doprowadziło badaczy i badaczki do przeciwnych wniosków dotyczących przemocy domowej. Pierwsza grupa uznaje, że kobiety i mężczyźni w równym stopniu stosują przemoc w związkach, natomiast druga zauważa znaczną asymetrię, wskazując, że sprawcami zdecydowanie częściej są mężczyźni. Przedstawiona została również koncepcja pozwalająca pogodzić te dwa spolaryzowane podejścia – typologia przemocy w związkach intymnych Michaela Johnsona. W końcowej części artykułu autorka wskazuje, że pomimo złożoności omawianego zagadnienia, kontrowersji wokół prowadzonych badań oraz pojawiających się rozbieżności w ich wynikach możliwa jest odpowiedź na pytanie, czy przemoc domowa ma płeć
CRL4DCAF1ubiquitin ligase regulates PLK4 protein levels to prevent premature centriole duplication
Authors: Grossmann Josina , Kratz Anne-Sophie , Kordonsky Alina , Prag Gali , Hoffmann Ingrid
Published: March 2024

Centrioles play important roles in the assembly of centrosomes and cilia. Centriole duplication occurs once per cell cycle and is dependent on polo-like kinase 4 (PLK4). To prevent centriole amplification, which is a hallmark of cancer, PLK4 protein levels need to be tightly regulated. Here, we show that the Cullin4A/B-DDB1-DCAF1, CRL4DCAF1, E3 ligase targets PLK4 for degradation in human cells. DCAF1 binds and ubiquitylates PLK4 in the G2 phase to prevent premature centriole duplication in mitosis. In contrast to the regulation of PLK4 by SCFβ-TrCP, the interaction between PLK4 and DCAF1 is independent of PLK4 kinase activity and mediated by polo-boxes 1 and 2 of PLK4, suggesting that DCAF1 promotes PLK4 ubiquitylation independently of β-TrCP. Thus, the SCFSlimb/β-TrCPpathway, targeting PLK4 for ubiquitylation based on its phosphorylation state and CRL4DCAF1, which ubiquitylates PLK4 by binding to the conserved PB1-PB2 domain, appear to be complementary ways to control PLK4 abundance to prevent centriole overduplication.

Authors: Huang Kaiqi , Jie Xizhen , Li Xiaoyan , Liang Zhaoming
Published: March 2024

Objective: To investigate the efficacy and safety of low-frequency repetitive transcranial magnetic stimulation (rTMS) for the treatment of lower limb motor dysfunction after stroke. Methods: A total of 96 patients with stroke and lower limb motor dysfunction were enrolled in this study, and were randomly divided into the experimental group and the sham stimulation group using the method of calculator-generated random numbers. Both groups received conventional medication and rehabilitation therapy. The experimental group received 4 weeks of 1 Hz rTMS treatment in the primary cortical motor area (M1) of the healthy side, with the treatment coil tangent to the skull surface; the sham stimulation group underwent the same procedures as the experimental group, but the treatment coil was perpendicular to the skull surface instead. Lower-extremity subscale of the Fugl-Meyer Assessment (FMA-LE), Berg Balance Scale (BBS), gait analysis, and lower-extremity surface electromyography (LESEM) were performed in both groups before and after rTMS treatment. Results: All 96 patients completed the test with no shedding and no adverse reactions. After treatment, the FMA-LE score and BBS score of the 2 groups of patients were significantly improved as compared with the pre-treatment (P < 0.05), and the TUG test time was reduced as compared with the pre-treatment (P < 0.05). The true stimulation group had greater improvement in all assessment indexes than that of the sham stimulation group (P < 0.05). After treatment, the electromyographic activity of the tibialis anterior and rectus femoris muscles in the true simulation group improved significantly. The step length, step speed, and step frequency were also significantly improved in both groups after treatment, and the symmetrical ratio of step length and support time was reduced (P < 0.05). Comparison between the groups revealed that the true simulation group significantly improved after rTMS treatment as compared to the sham stimulation group (P < 0.05). Conclusion: 1Hz rTMS treatment safely and effectively improved motor and balance function in patients with post-stroke lower limb motor dysfunction.

Published: March 2024

This paper analyzes noun phrase (NP) ellipsis in Puzzle movie from English to Indonesian. The method used is the descriptive qualitative research method. The data source used is the Puzzle movie, while the data is in words, expressions, sentences, or paragraphs. This aims to find out NP Ellipsis in the subtitle Puzzle movie and translate it into Indonesian. NP Ellipsis is a mechanism that removes portions of noun phrases that can be recovered from context. It seems to be a tendency towards using lexical repetition in the translation of ellipsis, which raises the degree of explicitness in the translated text. Finally, NP Ellipsis is resulting in ambiguity because this research shows that NP Ellipsis is not always translated accurately.

„Parys-Berlin“ als Labor für die Ausarbeitung der modi co-vivendi. Zur Abrechnung mit der Vergangenheit in der Spannungsliteratur
Authors: Borzyszkowska-Szewczyk Miłosława
Published: March 2024

„Parys-Berlin“ ( Justyna Sobolewska 2015) wird in der Rezeption die Art und Weise, wie Magdalena Parys das Bild von Berlin schildert, bezeichnet. Ein Ort, wo die Vergangenheit die Gegenwart prägt und die große Historie − die biographischen Brüche von Protagonisten. Sie oder ihre Vorfahren sind in diese Metropole von Ost und West in verschiedenen historischen Zeiten mit unterschiedlichen Familiengedächtnissen geströmt. Unter ihnen spielen die Figuren mit polnischem Migrationshintergrund eine wesentliche Rolle. Berlin wird dabei zum Ort der inter- und transkulturellen Begegnung und zugleich zum Labor, in dem die modi co-vivendi (Zygmunt Bauman, Maria Mendel) von Gruppen unterschiedlicher Herkunft nicht ohne Spannungen ausgearbeitet und -verhandelt werden.

Im vorliegenden Beitrag wird insbesondere zwei Fragen nachgegangen: Wie wird das Bild vom gegenwärtigen Berlin als der Hauptstadt des vereinten Deutschlands von der deutsch-polnischen Autorin konstruiert? Wie werden unterschiedliche Vorstellungen und Strategien von der Aufarbeitung der Vergangenheit, wie der Zweite Weltkrieg, (Zwangs-)Migration sowie der Umbruch 1989/90, in den Kriminalromanen der deutsch-polnischen Autorin Magdalena Parys dargestellt und reflektiert. Der Focus wird auch auf die Ermittlerfiguren mit polnischem Migrationshintergrund gelegt, die als Grenzgänger inszeniert werden.

Penentuan Hari Baik Dalam Acara Pernikahan Diintegrasikan Dengan Aqidah ASWAJA Nahdliyin
Authors: Lestari Arum Ayu
Published: March 2024

Indonesia is an archipelago country with a diverse culture. One of them is the Javanese tradition of determining the day of marriage. The determination of the day of marriage is a way for the Javanese people to determine the compatibility of the two prospective couples by calculating the value of the birth dates of the two couples before the day of the marriage is determined. Many marriages have failed to be held, which has caused conflict between the two families, only because one party believes in the good day determined by the person considered to be an elder, a wise man, or a shaman. This is certainly contrary to the beliefs of the Aswaja Nahdliyin akidah taught by Imam Hasyim Asyari. The purpose of this study is for readers from both academic and general audiences to know that determining a good day in Islam is not prescribed and can affect a person's faith. This study uses a descriptive method, with data collection techniques using interviews, observations, documentation, literature, and analyzing data using qualitative techniques. The results of the study found that the process of determining a good day to carry out a marriage is not an Islamic teaching, but rather a legacy of the local ancestors. In practice, before the day of the marriage contract is carried out, people who want to get married go to people who are considered to be knowledgeable about this matter to ask for consideration and calculation based on primbon calculation of good days to ask for consideration and calculation based on primbon to determine a good time for the marriage contract. However, according to the view of the Aswaja Nahdliyin akidah, this can damage a person's faith or belief in their creator, because without them realizing it, they have believed in something other than Allah Swt and they also do not believe that misfortune is actually a decree from Allah Swt. Besides that, Allah Swt does not like someone who blames time era because the one who created time era is Allah Swt.

The effective management of construction sites is crucial for minimizing risks such as lost productivity, injuries, and theft and ensuring the successful completion of projects. Site management encompasses applying scientific methods and evaluation criteria to plan and organize various production factors, including workforce, machinery, and materials. Managing these factors is vital for transforming raw materials into the final product. Inefficiencies in site management often lead to increased rework, defects, delays, disputes, and cost overruns, affecting construction projects. This study evaluated a construction project in Hargeisa, utilizing six established construction site management practices as assessment criteria. The findings reveal significant shortcomings in the site management practices, with 15 key items within these practices either partially performed or not performed. These inadequacies mirror the broader challenges construction sites face in Hargeisa, highlighting the need for a more robust and comprehensive site management approach. The study’s findings indicate that implementing an improved site management procedure is critical for the long-term sustainability of the construction industry in Hargeisa. Such improvements are essential for enhancing project efficiency, reducing costs, and safeguarding the health and safety of workers and all individuals involved in the construction projects. Based on the evaluation, the study proposes specific recommendations to address these shortcomings, aiming to contribute to advancing construction site management practices in the region. These recommendations could significantly improve project outcomes, worker safety, and industry standards.

Authors: Uyanık Sertaç , Sümer Ali
Published: March 2024

This research was a one-year study to investigate how increasing rates of humic acid affect the nutrient elements [Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu)] of olive trees (Olea europaea) of 14 years old found in a private cultivation land located in Bozköy of Geyikli, Çanakkale (Latitude 35 S 431667, Longitude 4409876) in 2018. The humic acid used was a suspension of 15% humic and fulvic acid, which was a commercial product (Blackjak SC, pH 4-6). Different concentrations of humic acid [0 (control), 50, 100, 200, 400 mL tree-1] were applied directly to soil of 20-30 cm depth under canopy projection of trees after dissolving in 10 L of water in April. A randomized block design with four replicates and five doses was adopted on 20 trees. 200 leaf samples were taken in December from annual shoot tips as reciprocal leaf couples and nutrient element analyses were carried out. The macronutrient elements N and P significantly increased upon all humic acid applications. However, the changes in the elements K, Ca, Mg, Fe, Zn, and Mn were insignificant in all applications. Humic acid at all concentrations decreased copper in leaves. As a result, addition to routine farmer fertilization, humic acid application at the rate of 50 ml tree-1 was determined to be the sufficient dose for olive trees. Moreover, this mentioned dose is considered to be the most economical dose besides being the most suitable one.
Soil Contamination by Metals/Metalloids around an Industrial Region and Associated Human Health Risk Assessment
Authors: Demirtepe Hale
Published: March 2024

Industrial, agricultural, transportation, and waste management activities cause soil contamination by metals/metalloids. Soil contamination is an essential global concern since it poses a significant risk to human health. Particularly in areas near heavy industry, people are more prone to exposure. This study aims to determine current metal/metalloid contamination levels in soil from Aliağa industrial region and assess associated health risks. Five surface soil samples were collected from the region, representing residential, agricultural areas, and downwind of possible sources. Pollution indices were calculated to determine the metal(loid)s with anthropogenic inputs, and a human health risk assessment was conducted. As a result, significant to extreme enrichment of arsenic (As), moderate to significant enrichment of zinc (Zn) and manganese (Mn), and very high enrichment of lead (Pb) and cadmium (Cd) were observed in soil samples. Possible sources of contamination were iron and steel facilities with electric arc furnaces and oil combustion. Non-carcinogenic risk assessment revealed acceptable risks of exposure to Aliağa soils, while exposure scenarios had a great impact on estimated risks. Arsenic, chromium (Cr), and Pb appeared to be significant contributors to non-carcinogenic risk. Carcinogenic risks associated with exposure to As, Pb, Cr, cobalt (Co), and Cd in soils were evaluated to be at an acceptable level. This study only considered soil exposure pathways; hence, a comprehensive risk assessment is deemed necessary not to underestimate the risk of living around an industrial region. Nevertheless, the study provided crucial information for the current hot spots for metal(loid)s in the region and human exposure level.
Recent Engineering Applications for Noise Reduction in an Automotive Industry

Published: March 2024

Industrialization harms as it results in the emission of noise into the surroundings and employees. Especially noise is one of the most common causes of hearing disorders and one of the most common occupational diseases in the industry. Reducing the main noise sources has become increasingly urgent since the effect on employee health was negative. Although noise reduction is an important issue in the industry, previous research has not addressed it adequately, particularly in the automotive industry. This paper presented a detailed case study on the reduction of noise in a pilot area of an automotive assembly line. The paper aimed to improve the quality of the working environment by reducing the use of Personal Protective Equipment (PPE) and noise reduction. For this purpose, noise measure tools were used: a Svantec-type noise dosimeter and a sound level meter. In the course of studies, it was creating noise maps (before/after), in order to verify whether the proposed measures will be sufficient. Once the proposed measures have been implemented, a 14.2% reduction in noise levels helped ensure employees’ safety by reducing the need for mandatory PPE. Meanwhile, the noise reduction percentage for AGV is the highest among the five noise sources, at 20.9%. Results showed that the sound pressure levels dropped from 110 dBA to 87 dBA and reduced on average for AGV. Reducing reliance on PPE and implementing noise reduction measures enhances pilot area safety and contributes to a more ergonomic and sustainable work environment. The implementation of this case, the application of the suggested measures, and the subsequent verification approved a considerable reduction in the noise levels in the influenced pilot area, and the measures applied were assessed as highly effective with result rates.

Authors: Orak Ceren , Ersöz Gülin
Published: March 2024

Oxytetracycline (OTC) is a commonly used antibiotic. It can be absorbed to a limited extent by both humans and animals, so it can be detected at various levels in different water sources. Its presence in rivers or water and wastewater streams can pose serious problems for human and environmental health, and therefore, it needs to be treated. OTC degradation was studied using iron-doped g-C3N4 through a photo-Fenton-like oxidation process under simulated sunlight. In this study, the effects of key reaction parameters such as pH (3, 6, 9), catalyst amount (0-0.8 g/L), initial hydrogen peroxide concentration (HP, 0-20 mM) on the degradation of oxytetracycline were studied. The optimal reaction conditions for OTC degradation were found to be pH=6, catalyst amount of 0.4 g/L, and HP of 10 mM. Subsequently, the temperature effect was examined at the optimum reaction conditions. Based on the results, at 25, 35, and 45 °C, OTC degradation was found to be 51.1%, 60.8%, and 76.7%, respectively. The kinetic study conducted revealed that the observed reaction follows a second-order reaction kinetic model. In addition, the activation energy of observed reaction was found to be 86.96 kJ/mol.
