Published: October 2024

Introduction: Rhinophyma, a severe manifestation of rosacea, is characterized by hypertrophy of sebaceous glands and fibrosis of the nose, often leading to significant aesthetic and functional impairments. Surgical treatment is the preferred approach for advanced cases to restore nasal appearance and function. Case Report: We present the case of a 60-year-old man with moderate rhinophyma and nodules on the nostrils. Surgical management under local anesthesia involved the use of thermal loops for excision of the lesions and bipolar electrosurgery for hemostasis. The patient was also treated for rosacea with topical agents, including metronidazole and azelaic acid, and oral doxycycline for inflammatory lesions. Directed healing followed the surgery, along with LED phototherapy and ablative erbium laser sessions to optimize results. Discussion: The use of thermal loops and electrosurgery allowed for precise excision and control of bleeding. Postoperative care, including daily greasy vaseline dressings, facilitated rapid healing. Mild infection at the excision sites was treated with topical and prophylactic antibiotics. Six sessions of LED therapy combining four types of light (infrared, red, yellow, and blue) improved healing and reduced inflammation. Ablative erbium laser was proposed to further enhance the aesthetic outcome. Conclusion: A combined surgical approach and careful postoperative management yielded satisfactory results in the treatment of rhinophyma.

In the 19th century, the discovery of penicillin revolutionized medicine, saving millions from infectious diseases. People believed that they had won the war against infections. However, the misuse and abuse of antimicrobial agents are accompanied by major ramifications like antimicrobial resistance, creating drug-resistant superbugs. This issue is concerning worldwide, as dwindling effective antibiotics lead to rising healthcare costs, re-hospitalization, and disease severity. Consequently, multiple initiatives have been undertaken to address these phenomena, including the development of antimicrobials with novel modes of action. Without novel discoveries of newer antimicrobial agents, we may face the risk of entering a post-antibiotic era where uncomplicated infections become untreatable. Ultimately, the morbidity and mortality rate would rise higher than in the pre-antibiotic era. This study highlights the recent developments in antimicrobials over the past five years and explores the strategies employed by the new generation of drugs to act against resistance. For example, we discuss the treatment of Carbapenem-resistant Enterobacteriaceae, such as Klebsiella pneumoniae Carbapenamase-producing Gram-negative bacteria, by using meropenem-vaborbactam. Plazomicin, lacking a hydroxyl group, effectively combats metallo-beta-lactamase, which meropenem-vaborbactam is unable to address. It is also preferred over tobramycin and gentamicin due to its hydroxyethyl group. Furthermore, we explore the conjugation of nanoparticles with antibiotics, which demonstrated synergistic effects and positive outcomes on different bacterial resistance. Mechanisms include increased drug adhesion to bacterial cell walls, generating oxidative stress, and causing mistranslation by detaching ribosomes from tRNA. Additionally, the IspH inhibitors like 4’-flurouridine targeting the MEP pathway which is also included in the discussion. This report thoroughly examines newer generations and classes of antibiotics, highlighting the improvements made by scientists to combat bacterial resistance effectively.
Forms of sacred buildings inspired by mountain sculpture. References to geological forms in the design of small contemporary mountain chapels
Authors: Cichosz-Fornalczyk Justyna , Cieślak-Arkuszewska Adriana
Published: October 2024

For centuries, architects have been inspired by nature, mimicking forms or observing phenomena and translating the principles of the natural environment into the structure of a building. The conscious mimicking of nature is mainly based on biological forms, but architects also draw on patterns derived from geomorphic features. Important sources of architectural inspiration among the inanimate elements of nature are mountains as models of beauty, stones and rocks as “indestructible” elements, and rock crystals as symbols of perfection and light. The aim of the study is to attempt to analyse and interpret the building lumps of selected small chapels from the Alpine region in terms of their reference to the motif of mountains or rock crystals and the means of architectural expression used for this purpose. The article discusses the principles of form, colours, materials used, the relationship to the natural landscape and the symbolic meanings of the buildings. It has been shown that the buildings analysed bear the characteristics of organic architecture and reflect the relationship between human spirituality and nature. In them, architecture becomes a means of expression that is accentuated by the spiritual element of art.
The use of precast concrete façade elements in selected projects of new Polish public buildings. Formal meanings and technology
Authors: Charciarek Marcin
Published: October 2024

The article is a presentation of selected examples of Polish public architecture as an attempt to search for contemporary architectural meanings and their expression in prefabrication concrete technologies. Prefabrication – increasingly visible in the Polish scenery – is not only becoming a construction alternative to monolithic systems, but is also chosen by architects as the ideal technology to implement their aesthetic intentions. An additional goal of the work is to analyse available sources on the topic of prefabrication of concrete façade solutions, in terms of their impact on the aesthetic expression of architectural objects, and to present the selected type of prefabrication through technical and construction details. Contemporary concrete architecture is increasingly subject to prefabrication due to higher technical and quality requirements. The cited patterns of application of modular façade solutions prove that they do not have to limit the architect’s design freedom and can be an alternative to leaving the beaten tracks of monolithic concrete construction.

Published: October 2024

The direct reduction–magnetic separation process based on coal is considered to be one of the most important methods that can effectively utilize high-phosphorus oolitic hematite. In this study, the mechanism of the effects of CaCO3 and Na2CO3 on the dephosphorization of high-phosphorus oolitic hematite during the direct reduction process was investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The results showed that Na2CO3 and CaCO3 reacted with Al2O3 and SiO2 during the direct reduction process, inhibited the generation of hercunite (FeAl2O4) and fayalite (Fe2SiO4), and promoted the reduction of metallic iron (Fe). Furthermore, the reaction inhibited the reduction of apatite and prevented the generation of FeP2. Na2CO3 could change the form of phosphorus in the gangue from Ca3(PO4)2 to Na2Ca4(PO4)2SiO4. Increasing the dosages of Na2CO3 and CaCO3 in the dephosphorization agent and increasing the content of Na2CO3 in the dephosphorization agent were beneficial to the growth of metallic iron particles, and increasing the dosage of Na2CO3, CaCO3 in the dephosphorization agent had more significant effects on metallic iron particles than increasing the content of Na2CO3 in the dephosphorization agent. The research conducted in this study is expected to provide a basis for the effective exploitation of complex and refractory iron ores.
A comparison of dry and wet grinding on gold-bearing sulphide ore flotation
Authors: Oluklulu Semih , Bozkurt Volkan , Ucbas Yasar
Published: October 2024

This study investigates the hypothesis that dry grinding prior to flotation can mitigate the adverse effects of galvanic interactions, improve the selectivity of gold flotation compared to wet grinding, and offer additional benefits due to water scarcity concerns and high water treatment costs. The effects of dry and wet grinding on the flotation behavior of gold-bearing sulphide ore were studied comparatively in terms of flotation test results and pulp chemistry parameters (pH, Eh, and dissolved oxygen). In addition, flotation tests without conditioning were also conducted following dry grinding in an attempt to minimize water contact further. Results demonstrated that dry grinding increased pulp potentials and dissolved oxygen levels, implying more oxidative conditions. Despite a lower mass pull with dry grinding, flotation recoveries and grades of gold and chalcopyrite were comparable to wet grinding, while dry grinding enhanced pyrite flotation at the rougher stage. Notably, flotation without conditioning effectively rejected pyrite and achieved higher grades for gold and chalcopyrite, indicating selective flotation. Therefore, dry grinding before flotation emerges as a viable alternative for gold and chalcopyrite flotation due to its improved selectivity while carefully optimizing flotation strategies and reagents to maximize recoveries.

Published: October 2024

. In all modes of travel, gastronomy is pivotal in enriching the tourist experience. This study aims to identify indigenous cuisines and gastronomic tourism in Nigeria. A qualitative approach was employed, using a phenomenology study through interviews and samples drawn from purposive populations. Snowball techniques were employed to identify potential interview participants from the selected tourist destination communities of Ikogosi, Ikegun, Ikija, and Agodi. This study developed four significant themes to which participants, including community members and destination managers, responded: identifying indigenous cuisines from the community, variations in food trends, popular cuisines for gastronomy tourism, and the food history associated with the community. The findings from interviews highlighted culinary diversity despite shared ethnic backgrounds. It shows the variant in preparation of Amala using different root tubers, showcasing regional variations, such as Amala lafun in Abeokuta and Amala isu in Ibadan. The research also notes significant differences in soups, stews, and cooking methods, particularly in fishing communities like Ikegun, where seafood and spicy dishes dominate. Traditional foods and cuisines, including Feregede, Otili and Kokondo and medicinal soups such as Marugbo, Tegi, Ogbagba and Isapa, are increasingly disappearing due to modernisation, changing dietary preferences and lack of documentation. This poses a risk to preserving indigenous knowledge, primarily held by older generations. The findings also emphasise the potential for gastronomy tourism, proposing that local cuisines can attract visitors while contributing to economic sustainability. Suggestions for promoting traditional dishes, such as Pounded yam, Amala and Abula, are highlighted as part of a broader strategy for culinary heritage preservation. In conclusion, proper methods for preserving and documenting indigenous cuisines specific to each community should be implemented. Engage the tourism sectors with local hotels, restaurants, and travel agencies to improve authentication and create packages highlighting traditional cuisines and attractions. Establish indigenous food museums, where the history of cuisines is preserved for future generations, and develop robust infrastructural planning for good road networks to access communities and hospitals, potable water, and proper drainage systems to mitigate flooding in vulnerable areas

Psychiatric presentation and somatic complications in anti-glutamic acid decarboxylase (GAD) antibodies: A case report
Authors:   “Prof. Dr. Alexandru Obregia” Clinical Psychiatric Hospital, Bucharest, Romania, Sopu Andreea
Published: October 2024

Autoimmune encephalitis represents a rapidly evolving group of immune-mediated disorders characterized by brain inflammation and neuropsychiatric symptoms, resulting from antibodies targeting neuronal cell surface proteins, ion channels, or receptors. Among the antigens involved, autoantibodies against NMDAR, AMPAR, GAD, GABA-AR/BR, LGI1, CASPR2, mGluR5, DPPX, and Neurexin-3a are significant in the pathogenesis of autoimmune encephalitis (AE) in adults. Glutamic acid decarboxylase (GAD), specifically its isoform GAD65, is a key enzyme in the production of GABA, and its antibodies are associated with conditions like temporal lobe epilepsy and various neurological syndromes including stiff-person syndrome (SPS), limbic encephalitis, and cerebellar ataxia. Psychiatric symptoms, such as behavioral changes, memory loss, and executive function impairment, are common in anti-GAD antibody-associated encephalitis. We present the case of D.B.-V., a 40-year-old male with no psychiatric history, who developed severe neuropsychiatric symptoms leading to a diagnosis of anti-GAD autoimmune encephalitis. Initial symptoms included headache, fever, and rapid progression to severe confusion and altered consciousness, requiring intubation. MRI findings and anti-GAD antibodies in the cerebrospinal fluid confirmed the diagnosis. Despite immunotherapy with IVIG, plasmapheresis, and Rituximab, the patient remained agitated and noncompliant, necessitating psychiatric intervention. The management was complicated by infections and fluctuating metabolic parameters, highlighting the need for a multidisciplinary approach. After significant medical and psychiatric treatment, the patient was transferred to a specialized nursing home, with persistent cognitive and functional impairments. This case underscores the importance of early recognition and a comprehensive, multidisciplinary approach to managing autoimmune encephalitis, addressing both neurological and psychiatric symptoms to improve long-term outcomes.

Published: October 2024

This paper examines the current state of the gender gap in literacy rates and school education among Adivasi populations in India. Despite significant progress in overall literacy rates in recent decades, Adivasi communities, particularly Adivasi girls, continue to lag behind. We analyze the latest data from the Census of India, National Family Health Surveys, and other government reports to quantify the extent of the gender gap in literacy and school enrollment, attendance, and dropout rates among major Adivasi groups across different states. Root causes including poverty, lack of access to schools, cultural norms, early marriage, and lack of female teachers are explored. The paper also reviews recent government initiatives and welfare schemes aimed at promoting education of Adivasi girls and reducing gender disparity. Based on the analysis, targeted policy recommendations are made to accelerate progress in closing the gender gap and ensuring basic school education for all Adivasi girls in India.

Hereditary Tyrosinemia Type I (HT1) is a rare metabolic disorder caused by a deficiency in fumarylacetoacetate hydrolase, leading to the accumulation of toxic metabolites and resulting in hepatic and renal complications. This case report details a 10-year-old patient from a consanguineous family with a significant history of hepatic failure due to hepatocellular carcinoma. The patient presented with abdominal pain, jaundice, and urinary abnormalities, which led to the diagnosis of HT1, confirmed by elevated succinylacetone levels. Despite initial treatment with nitisinone and a low-protein diet, surgical resection of the hepatic mass was impeded by vascular invasion, necessitating preoperative chemotherapy. This case underscores the importance of early detection and a multidisciplinary approach in managing HT1, highlighting ongoing research into advanced therapies and genetic interventions to improve patient outcomes.
Nymphaea lotus Distribution in Oguta Lake: Implications for Heavy Metal Pollution in Surface Water and Sediments
Authors: Agbanelo Chineze , Unamba Chibuike , Akalazu Jacinta
Published: October 2024

Water quality is increasingly deteriorating and has affected lakes, which are important sources of freshwater. Heavy metals are of great concern because they are mostly toxic and resistant to decomposition. Aquatic macrophytes serve as stable biological filters that purify water bodies by accumulating dissolved metals and toxins in their tissues. Given their ability to trap various toxic heavy metals, the macrophyte Nymphaea lotus, which is observed on the surface waters of Oguta Lake, was studied to estimate the concentrations of six heavy metals in the water, sediment, and macrophytes. This was achieved by studying the spatial and temporal distribution of Nymphaea lotus in the lake and analysing the concentrations of heavy metals in the surface water, macrophytes, and sediment samples. Descriptive statistics, exploratory data analysis, and correlation analysis were used to analyse data obtained. Results revealed that the population of Nymphaea lotus declines over time from June to November in all regions. Upstream had the highest concentration of macrophytes (64%), while the downstream area has the lowest (2%). The heavy metal concentrations in the three samples ranges from 0.16 mg/kg to 2.96 mg/kg in sediments and Nymphaea lotus, and from 0.16 mg/L to 2.16 mg/L in water, with lead showing the highest concentration across all sample type. This highlights heavy metal contamination in the lake. The sparsely populated Nymphaea lotus exhibits selective bioaccumulation of lead, mercury, and zinc, while it seems to exclude or inefficiently absorb arsenic and chromium. Correlation analysis suggests a close interdependence between the concentrations of metals in sediments, water, and macrophytes, with sediments playing a key role in both water contamination and macrophyte metal absorption. Corrective and preventive measures should be taken to restore the lake.

The Reliability of YouTube as an Information Resource for Parents About Retinopathy of Prematurity
Authors: Alacamli Goksu , Yakar Konuralp
Published: October 2024

Purpose

To investigate the quality and reliability of YouTube videos about retinopathy of prematurity (ROP) to direct parents of infants with the disease to access more accurate content.

Methods

The term “retinopathy of prematurity” has been searched on YouTube containing all of the videos between January 2 and February 2, 2024. The first 200 videos were evaluated by two ophthalmologists. Duplicated-split videos, videos shorter than 60 seconds, videos presented in languages other than English or with an incomprehensible accent, and videos unrelated to ROP were excluded. Video uploaders, types, continental origins, durations, and viewer interactions were noted. DISCERN, The
Journal of the American Medical Association
(JAMA), and the Global Quality Score (GQS) scoring systems were used to evaluate the quality of the videos.

Results

The mean quality of all videos was poor in all scoring systems. Academic societies and medical institutes scored highest in video uploaders, followed by physicians; patient experience videos had the lowest quality. Of the video types, the medical education seminars were of the highest quality. Although a strong positive correlation was detected between video duration and video quality, this same strong correlation was not observed between viewer interactions and video quality. There was no significant difference between video origins in terms of video quality.

Conclusions

It would be wiser to direct the parents of patients with ROP to watch longer videos uploaded by the academic community, medical institute, or physicians, and to watch the medical training seminars. Also, it might be important to warn them not to take user interactions too seriously.

De la inversión a la representación. Para una relectura del “Manuscrito de Kreuznach” de Karl Marx
Authors: Sucksdorf Cristián
Published: October 2024

Este trabajo analiza el aporte de Marx en el “Manuscrito de Kreuznach”. En primer lugar, se explicitan las continuidades y diferencias con Feuerbach respecto del filosofema de la inversión de sujeto y predicado. En relación a esa influencia, se estudian luego otros modos de la crítica de Marx a Hegel, como la crítica de la conversión de la empírea en metafísica. Finalmente se analiza cómo en la concepción de Marx de la soberanía estatal y monárquica como forma representada de la soberanía popular despunta una ruptura filosófica con los esquemas tanto de Feuerbach como de Hegel.
El cristianismo entre ascética y mística en Las confesiones de la carne. Reflexiones de un patrólogo
Authors: Morales Xavier
Published: October 2024

Para el especialista de la historia del cristianismo antiguo, en su opus posthumum, Les aveux de la chair, Michel Foucault tiende a retener solo los elementos del cristianismo que hacen de él una institución ética. Ahora bien, entre la fecha de composición de Las confesiones de la carne (1982) y la muerte de Foucault (1984), la investigación sobre la parrhesia abrió un espacio para otra manera de pensar el cristianismo, más allá de lo ético, algo similar a “la forma del otro mundo y de la vida otra” con la que Foucault describe al cinismo en sus últimas palabras escritas, y deja prever una bipolaridad ascética y mística en la “construcción del sujeto moderno”. Por lo tanto, es necesario releer Las confesiones de la carne a partir de las últimas reflexiones de El Coraje de la verdad.
Juicios políticos apasionados y democracia de los afectos. Reflexiones desde la teoría del juicio y el giro afectivo
Authors: Muñoz Sánchez María Teresa
Published: October 2024

Este artículo parte de la idea de que las emociones y los afectos están en juego en el proceso de discernimiento. Tiene como horizonte explorar la posibilidad de que las emociones permitan gestar espacios democráticos de articulación de lo común. De manera que el objetivo específico del texto es defender un modelo de democracia de los afectos. Para alcanzarlo sostiene que, si pensamos con cuidado una teoría del juicio poniendo atención al papel que juegan los conceptos y, al mismo tiempo, repensamos la emociones como relaciones sociales más que como afecciones internas, es inevitable colocar a los afectos en estrecha vinculación con los conceptos. Siendo así, los juicios políticos que articulan la vida democrática deben entenderse desde su condición de estar atravesados por las pasiones, o, dicho de otro modo, ser juicios apasionados.

Published: October 2024

In recent years, the field of image processing and computer vision has been deeply transformed by the advent of Convolutional Neural Network (CNN). These deep learning models, inspired by biological processes, have demonstrated remarkable success in tasks such as image classification, object detection, and semantic segmentation. A critical component of this success is feature extraction, where the pooling layer within CNN serves as a nonlinear down-sampling technique. This layer reduces the spatial size of the convolved feature map through operations like average or maximum pooling, significantly impacting the model’s performance in complex tasks. This research introduces a novel pooling algorithm, Right-Neighbor Deviation (RND), designed to enhance the performance of CNN. The RND pooling method aims to capture detailed spatial features and hierarchical representations more effectively, thereby improving the accuracy and resilience of deep learning models. A dataset of multi-class brain tumor classification, incorporating MRI images from the BR35H dataset, is utilized to explore the potential benefits of RND pooling compared to traditional methods. The effectiveness of the proposed method is evaluated using performance metrics including accuracy, precision, recall, and F1 score, achieving generalized values of 98.86%, 98.84%, 98.80%, and 98.80%, respectively. The results highlight the potential of RND pooling to significantly advance the state of the art in brain tumor classification using CNNs, potentially leading to improved diagnosis and treatment outcomes.

Analysis of literature sources and empirical data indicate a variety and a large volume of experimental material, which often characterizes the uncertainty and contradiction of information regarding the effect of sulphur and manganese on the corrosion behaviour of steels obtained using traditional methods. This leads to the need to search for new, alternative methods for its effective analysis. The task of assessing and predicting the corrosion properties of structural steels is a key one in the general problem of managing the operational reliability of welded metal structures and equipment for the chemical, metallurgical, oil and gas, mining and other industries. The possibilities of its solution consist of using new information technologies, a component of which is intelligent means of information processing, such as artificial neural networks (ANN). The use of ANN makes it possible to create qualitatively new hardware and software that significantly expand the classes of emerging problems and increase the efficiency of analysis and forecasting. In the process of long-term operation of metal structures in many industrial industries, the metal is in direct contact with sulfur-containing agents at high temperatures. This leads to the saturation of the surface layer of the metal with sulfur with a concentration of up to 0.6%, which further makes it impossible to carry out repair and welding operations due to the formation of hot cracks. It was found that adding metallic manganese into the electrode coating in an amount of 20-25% significantly increases (4-5 times) the resistance against the formation of hot cracks. Sulfur content in the deposited metal has the opposite effect on the appearance of hot cracks. So, with a sulfur content of 0.042% and more, the resistance of the metal against the formation of hot cracks decreases sharply. It is shown that an increase in the content of metallic manganese in the electrode coating significantly reduces the content of dissolved sulfur in the deposited metal. Moreover, this tendency is typical for steels with different sulfur content in the surface layers and with different service life. For example, for steel with a service life of 20 years, the initial sulfur content in the surface layer of the metal (up to 1 mm) was about 0.52%. Adding metallic manganese in the coating of electrodes in an amount of 20-25% made it possible to reduce the sulfur content in the deposited metal to 0.03-0.045%, i.e. 12.6-17.3 times. In addition, the corrosion rate decreases with an increase in the content of metallic manganese in the electrode coating. The lowest corrosion rate for all steels involved in the research was established at 20-25% manganese content in the coating.

Porous carbon is one of the promising electrode materials for supercapacitors due to its unique and engineerable microstructural properties. The study of the synthesis of porous carbon from waste biomass is very important due to the abundance of natural resources, low cost production and contribute to solving environmental problems. In this study, porous carbons derived from candlnut shell with various type of activator was studied the chemical structural, morphological and electrochemical properties then evaluated as electrodes for supercapacitor. We have been successfully synthesized of porous carbon from candlenut shells using three steps of the process, i.e.: carboni-zation, activation and calcination. Carbonization was carried out at 700°C in a furnace using a closed crucible to minimize the oxygen. The chemical activation conducted using three types of activators, i.e. ZnCl2, H3PO4 and KOH then calcination process by heated at 800°C for 1 h under Ar flow. The results of the Fourier-transform infrared (FTIR) analysis show that the carbonization process increases the content of aromatic C=C functional groups and reduce the OH, C-H, C-O and C=O functional groups. The carbonization process has also increased the electrical conductivity of the sample around 0.8525 S/m. The results of Scanning Electron Microscope (SEM) images can be observed that the activation process of carbon has formed which was indicated by the appearance of many pores on the surface area of carbon. N2 adsorption/desorption isotherms (Brunauer–Emmett–Teller (BET)) characterization was indicated that the porous carbon is dominated by mesoporous with a pore size around 2-50 nm. BET characterization also can be determined the surface area of porous carbon around 477 m2/g for ZnCl2, 636 m2/g for H3PO4, and 681 m2/g for KOH. This synthesized materials are further employed in a symmetric supercapacitor using simple glass cell. The best performance of supercapacitor achieved by KOH porous carbons with 16.30 F/g of specific capacitance, 2.26 Wh/kg of energy density and 1038 W/kg of power density.

The economic and technical advantages of 3D printing make it a possible replacement for conventional production processes, especially for complex products and small batches. It is important to point out that technological parameters of 3D printing, such as layer thickness, print density, print speed, melting temperature, and table temperature, have a significant impact on the mechanical properties and productivity of parts obtained by 3D printing. Because of all the above, there is a great interest in research in this area. The paper presents the results of testing the tensile strength of the ABS polymer, in which two parameters were varied: the thickness of the print layer (0.39 mm) and the print density of 60–100% in steps of 10% each. The samples were obtained on a ZORTRAX M200+ 3D printer using fused filament deposition (FDM) technology. The selected thickness of the printing layer is relatively large, and with it, parts with lower accuracy and high surface roughness are obtained, although at the same time high productivity is achieved, which can satisfy some requirements. The obtained tensile strength values show that increasing the print density leads to an increase in its value, with a deviation in the sample with a print density of 100%, whereas the tensile strength values are comparable to the values obtained by other authors.

In recent years, metal complexes and biopolymers have gained significant attention in environmental applications such as catalysis and heavy metal removal. Chitosan, a biopolymer derived from chitin, is well-known for its biodegradability, non-toxicity, and strong metal ion affinity, which can be further enhanced through Schiff bases to improve its catalytic and adsorption capabilities. The primary objectives of this study were to investigate whether Cu(II) complex of Chitosan Salicylaldehyde Schiff Base CSSB-Cu(II) can act as an efficient catalyst in hydrogen peroxide decomposition reaction and to find out the raw absorbent which has the highest Cadmium ion removal efficiency from among the absorbents Chitin (CT), Chitosan (CS) and Chitosan Salicylaldehyde Schiff Base (CSSB). CSSB was synthesized using the Schiff condensation reaction between the amino group of CS and the carbonyl compound of salicylaldehyde with the elimination of water molecules and it was complexed with Cu(II) ion to produce CSSB-Cu(II) complex. The catalytic effect of the CSSB-Cu(II) complex on the kinetics of the decomposition of hydrogen peroxide was investigated and compared with CSSB. CSSB-Cu(II) showed a better catalytic effect than CSSB and has a pseudo-first-order catalytic decomposition for H2 O2 . CT, CS, and CSSB were investigated as adsorbents for the Cd(II) removal to determine their cadmium removal efficiencies. This study concludes that the removal efficiency of CSSB was greater than that of CS and CT. The equilibrium data agreed more with the Langmuir model than with the Freundlich model. The IR and electronic spectral data confirm the presence of an imine bond and the existence of the complex in square planar geometry.
