Authors: Ngwamah J.S , Kayode V.O. , Saleh R. , Audu P.A.
Published: October 2024

The study was evaluated to determine the present pervasiveness of gastrointestinal intestinal parasites among school-aged children in  Lokoja, Kogi State, Nigeria. The study was carried out to relate the ambiguity among the different participants to gastrointestinal infections in relation to sexes, ages and their sociodemographic status. The investigation was carried out in 10 randomly selected primary  schools (5 public and 5 private). Four hundred samples (comprises of 212 male and 188 female) were collected and examined for  the presence of parasites. The ages of the participants ranged from 5-14 years, were examined microscopically by using direct smear  methods. Out of the 400 participants inspected 149 (37.25%) were found positive for some gastrointestinal intestinal parasites. 10 species  of intestinal parasites were came in contact with. Hookworm infection recorded the highest prevalence (10.50%) followed by Fasiola  hepatica (6:00%). Trichuris trichuira, recorded the least prevalence (1%). In the four different age groups, pupils of group 10-12 proved to  have higher prevalence than any other group investigated. The environmental factors are also considered as the major risk factors associated with infection intensity of gastrointestinal intestinal parasitic infections. The result showed water source, occupational status,  toilet system used by the participants determine their health status in relation GIPs. The result showed high prevalence in individuals  using river water (62.96%) for their domestic chores than any other source. The study indicated that intestinal parasites were prevalent in  the study area, and for this reason, control measures, such as chemotherapy, provision of adequate sanitary facilities, portable drinking  water, improved personal hygiene and health education should be the focus of community, government and non-governmental  organizations.

Published: October 2024

The integration of technology in accounting roles raises questions about the adaptability and skills of accountants in utilizing these tools  effectively. Understanding how accountants' behavior is influenced by technology is crucial for their professional development and the  accounting industry's future. This study focused on the development of a predictive model, leveraging both Naive Bayes and K-Nearest  Neighbors (KNN) models. The research methodology involved the use of Pandas DataFrame to establish a robust framework for the  dataset, incorporating both established and innovative features as input variables. These datasets were then utilized as the training data  for the predictive model, with the primary objective of extracting valuable insights for decision-making and forecasting accountant  behavior. The key findings of the study shed light on the performance of the different models employed. The Naïve Bayes model  emerged as a standout performer, achieving an accuracy rate of 63% and an exceptional recall rate of 97%. This underscores its  effectiveness in predicting accountant behavior, especially in identifying positive instances. On the other hand, the K-Nearest Neighbors  model displayed a balanced trade-off between precision and recall, achieving an accuracy rate of 52% and an F1 score of 64%. This  suggests that the model provides a reasonable compromise between accurately identifying positive cases and overall performance.  Furthermore, the hybrid KNN-NB model, which amalgamates elements from both approaches, also achieved an accuracy rate of 52%.  This finding indicates that the hybrid model has the potential to harness the strengths of both algorithms, offering a versatile approach  to predicting accountant behavior.

Published: October 2024

Transesterification tend to be the most adopted method of producing biodiesel, but the outcome is associated with high viscosity  especially at low temperature. Viscosity is the most important rheological property of biodiesel. This paper investigates the impact of  Cupper II Carbonate (CuCO3) nanoparticles on the rheology of biodiesel extracted from castor oil. The CuCO3 nanoparticles has been  subjected to Xray fluoroscopy (XRF) in order to determine its elemental composition. The crude castor oil was purified, trans-esterified  and CuCO3 nanoparticles were dispersed in the trans-esterified oil with concentration ranging from 0.1wt% to 1.0wt% in 0.1wt% interval.  Fourier Transform Infrared spectra (FTIR) was used to examine the functional groups of the transesterified sample. The samples were  subjected to viscosity measurement using digital viscometer at a temperature range of 20oC to 100oC at the interval of 20oC. The XRF  characterization shows that the CuCO3 nanoparticles used is pure due to the fact that its percentage concentration tends to be 92.11%.  FTIR analysis indicate that the ester (biodiesel) was achieved at 1744.4 peak. The viscosities of the samples decrease as the temperature increases and with the increase in the amount CuCO3 concentration. The viscosity tends to be best at the application of 0.3wt%. This  shows that CuCO3 nanoparticles can be used as biodiesel additive using castor oil as feedstock.

Authors: Awwa Aisha , Ladan Zakari , Myek Bako
Published: October 2024

This study focuses on optimizing the synthesis of ZnO/Kaolin nanoparticles and their application in adsorptive bleaching of palm oil. The  reaction mechanism involves the dissolution of metal oxides (Fe2O3, Al2O3, CaO, MgO) from clay lattices using mineral acids, increasing  the surface area and triggering ion exchange processes. The kaolin is beneficiated through crushing, washing, acid treatment, and  drying, and then activated with ZnCl2. Zinc oxide nanoparticles are synthesized using Moringa leaf extract and zinc acetate, followed by  the synthesis of ZnO/Kaolin composites using Central Composite Design (CCD) to optimize parameters like kaolin ratio, calcination  temperature, and time. The composites are characterized by XRD, XRF, and BET surface area analysis. The bleaching efficiency is  evaluated through absorbance and iodine value, with ANOVA analysis confirming the significance of dosage, temperature, and time. The  optimized conditions identified are essential for maximizing the composite’s adsorptive efficiency in palm oil bleaching.

Authors: Ibrahim Musa Saheed , Ikhajiagbe Beckley
Published: October 2024

Ferruginicity is a special condition when soil became rich in iron. This condition is characterized by high pH and reduced bioavailability of  plant limiting nutrients. Unfortunately, this type of soil covered 30% of arable lands in Nigeria. This research aimed at using a native plant  growth promoting bacteria (Bacillus cereus strain GGBSU-1, Klebsiella variicola strain AUH-KAM-9 and Proteus mirabilis strain  TL14-1) with phosphate solubilizing capabilities to remediate iron toxicity and improve soil nutrients, as well as soil micro-biota  colonization. Soil physico-chemical properties before rhizo-inoculation (FA), after 16 weeks of rhizoinoculation with the PGPB into the  rhizoid of a growing rice seedling (FB) and after 16 weeks of natural attenuation (FC) were analyzed. Phosphate solubilizing capacity of  the PGPB was investigated using a developed Pikovskaya’s growth medium. The results showed that FA is rich in iron and deficient in  bioavailable phosphorus and nitrogen (200.67 mg/kg, 8.01 mg/kg and 0.20%) respectively, as against the FB soil which showed moderate  iron and increased soil nutrients (51.22 mg/kg, 20.21 mg/kg and 0.33%). The presence of acidic exudates, which was indicated by a red  litmus paper at the rhizosphere in FB signifies the iron chelation capacity of the PGPBs resulting in iron remediation and soil nutrient  improvement. Furthermore, the significant increase in microbial population in the FB soil as against the FA and FC corresponds with the  SEM results at the root epidermis. Furthermore, other nitrogen-fixing bacteria such as Bacillus subtilis were observed to be active and  motile in the FB. This indicated the effectiveness of PGPB with PSB capacities in iron remediation and soil nutrient enhancement.

Published: October 2024

Urinary schistosomiasis is one of the most important tropical diseases, which has received insufficient attention in developing countries.  The burden of urinary schistosomiasis is further exacerbated by co-infection with bacterial Urinary Tract Infections (UTIs). This study was  aimed at assessing bacteria co-infection and the impact of urinary schistosomiasis on daily activities of women in Yala L.G.A in Cross River  State, Nigeria. Macroscopy, urinalysis, and microscopy were used to examine the 650 urine samples (400 from Okpoma and 250  from Ugaga villages) collected to determine presence of Schistosoma haematobium eggs. The presence of bacterial strains in urine  samples positive for Schistosoma eggs was evaluated using standard microbiological protocol. Questionnaires administered to women provided information on socio-demographic data and water-contact activities. Results revealed that out of the 650 urine specimens examined in the two villages, 202 (31.08%) were infected as overall prevalence. The highest prevalence (48.53%) was found among the  11-22 years age group, and the least (12.80%) among the 59- 70 years age group. Statistical analysis at significance level (P≤ 0.05)  revealed that there is a significant relationship between occupation and infection rate of schistosomiasis in the area. One hundred and  sixty women (72.07%) who were infected complained of suprapubic pain and painful urination. Also, the infection prevented them from  going to farm, market, carrying out their daily domestic activities (cooking, washing, fetching water), attending social functions, and  performing their functions as caregivers. A total of eight (8) bacteria genera were isolated and identified from 202 urine samples positive  for Schistosoma eggs. The bacterial species include Klebsiella sp. 3 (2.47%), Staphylococcus aureus 39 (32.23%), Enterococcus aerogenes 6  (4.95), Escherichia coli 32 (26,45), Pseudomonas aeruginosa 14 (11.57), Staphylococcus saprophyticus 10 (8.26), Enterococcus faecalis 9  (6.61) and Proteus sp. 8 (6.61). Significant bacteriuria was detected in 121 (59.90%) and co-infection was detected in 65 (53.68%) of schistosomiasis cases. This investigation revealed the impact of urinary schistosomiasis on the daily activities of the women and significant bacteriuria in the study area which suggest that bacterial presence may be a potent complication in the management of urinary schistosomiasis. The integration of complementary control strategies such as disease surveillance, chemotherapy, health education, potable water supply, provision of toilet facilities and sanitation in the study area would lead to great success..

Authors: Tyona Ngodoo Magdalene , Musa Nomsu
Published: October 2024

Onychomycosis, a prevalent fungal nail infection, poses a substantial public health challenge, particularly in tropical regions such as  Nigeria. This study investigates the phytocompounds, cytotoxicity and antifungal activity of Cymbopogon citratus extracts, as a source of  novel antifungal compounds for onychomycosis treatment. Gas Chromatography-Mass Spectrometry technique was employed for the  phytocompounds screening, while minimum inhibitory concentration and minimum fungicidal concentrations were determined using  standard method. The results revealed that a total of twenty-four (24) compounds were detected out of which 7 compounds were  assessed from the essential oil, extracts of methanol had five (5), ethyl-acetate (8), and hexane (4) compounds respectively. Compound  with the highest percentage height was Dodecanoic acid, 1,2,3-propane (6.48%). Hexane had higher MIC ranging from 0.232 µg/ml.  whereas diacetate had MIC range of 0.03-2 µg/ml, however essential oil (EO) showed the lowest MIC range of 0.03 -1 µg/ml as compared  to all other extracts and the control (Terbinafine) showing a MIC of 0.03-4 µg/ml. The antifungal potential of Cymbopogon citratus extracts,  particularly essential oil, was demonstrated against various fungal isolates. Essential oil consistently exhibited the lowest MIC  and MFC values, indicating potent antifungal properties. The study added valuable information to the growing body of evidence  supporting the antimicrobial efficacy of C. citratus extracts.

Published: October 2024

Cow hide, commonly known as ponmo, is an edible product derived from the skins of large animals such as cattle, camels, and buffaloes.  Ponmo is a popular delicacy in various regions of Nigeria. However, the unhygienic production practices of ready-toeat ponmo often lead  to contamination and spoilage by microorganisms. This study aimed to assess the bacteriological quality of ready-to-eat cow hide  (ponmo) sold by roadside vendors in Makurdi metropolis. Ten samples of ready-to-eat ponmo were collected from roadside vendors in  five different markets: Wadata Market, Wurukum Market, North Bank Market, High-Level Market, and Modern Market. The samples were  washed in distilled water, serially diluted and inoculated onto different media (Nutrient Agar and MacConkey Agar) using the pour plate  method, followed by incubation at 37°C for 24 hours. The bacterial isolates were identified based on cultural, microscopic, and  biochemical characteristics, revealing the presence of Staphylococcus aureus, Escherichia coli, Bacillus spp, and Proteus spp.  Staphylococcus aureus was the most prevalent bacteria (46.67%), followed by Escherichia coli (35.56%). Statistical analysis indicated no significant difference (P ˃ 0.05) in bacterial load among the samples, with total bacterial counts ranging from 2.50 x 10^5 to 2.75 x 10^5  CFU/g. The presence of these bacteria, some of which can cause food borne illnesses, highlights the public health risks associated with  consuming ready-to-eat ponmo. This study underscores the need for enhanced monitoring of ready-to-eat products and increased public  health education for both vendors and consumers.

Published: October 2024

Food workers play a crucial role in ensuring food safety. Implementing a novel sanitation technology requires providing workers with the tools and knowledge to feel comfortable using it. This study focuses on potential challenges in the adoption of superheated steam as surface sanitizer equipment for food processing industries. Superheated steam has emerged as a promising tool for dry sanitation. Because it works at temperatures ranging from 125°C to >300°C, evaluating worker safety hazards associated with its use is paramount. A trial with 24 participants was conducted. Participants received an in-person synchronous training presentation, operated a pilot unit, and provided feedback via survey. Results showed that 46% of participants considered the time and accuracy to operate the equipment as the biggest limitation, followed by its weight (42%). Almost half (42%) of the participants changed their perception of the technology after training. Active learning strategies used in this study could improve operational outcomes and knowledge transfer related to superheated steam technology and use because 83% of participants felt confident in explaining the technology to others. Our findings offer a perspective about the interconnected factors that influence the adoption of a technology that, if operated by trained personnel, could improve sanitation.

Published: October 2024

The lack of proper cleaning and sanitizing practices on natural food-contact surfaces can lead to foodborne illness outbreaks. This study was conducted to evaluate the efficacy of cleaning and sanitizing methods for reducing Salmonella inoculated onto banana leaf and bamboo basket surfaces. Surfaces were inoculated with a Salmonella cocktail and assigned to a combination treatment of cleaning and sanitizing methods. Three cleaning methods were evaluated (wiping, scrubbing, or no cleaning) alone or in combination with 200 ppm of bleach or 400 ppm of peracetic acid (either applied for 3 or 5 min) or no sanitizing. Regardless of cleaning method or contact time, peracetic acid reduced Salmonella on banana leaves to a level below the limit of quantification (<1.44 log CFU/cm2). The efficacy of sanitizing with bleach for banana leaves differed depending on the cleaning method (P = 0.044). Bleach applied for 5 min with wiping was most effective and reduced Salmonella on banana leaves to 2.85 log CFU/cm2 (95% confidence interval: 2.52, 3.18). For bamboo baskets, the most effective treatment was sanitizing with peracetic acid for 5 min regardless of cleaning method (P < 0.0001). This study offers insights for controlling Salmonella on food-contact surfaces commonly used in Cambodian fresh food markets.
Sodium glucose cotransporter 2 inhibitors in the management of heart failure: Veni, Vidi, and Vici
Authors: Bhandari Monika , Pradhan Akshyaya , Vishwakarma Pravesh , Singh Abhishek , Sethi Rishi
Published: October 2024

Heart failure (HF) is a chronic disease associated with high morbidity and mortality rates. Renin-angiotensin-aldosterone system blockers (including angiotensin receptor/neprilysin inhibitors), beta-blockers, and mineralocorticoid receptor blockers remain the mainstay of pharmacotherapy for HF with reduced ejection fraction (HFrEF). However, despite the use of guideline-directed medical therapy, the mortality from HFrEF remains high. HF with preserved ejection fraction (HFpEF) comprises approximately half of the total incident HF cases; however, unlike HFrEF, there are no proven therapies for this condition. Sodium glucose cotransporter-2 inhibitors (SGLT-2is) represent a new class of pharmacological agents approved for diabetes mellitus (DM) that inhibit SGLT-2 receptors in the kidney. A serendipitous finding from seminal trials of SGLT-2is in DM was the significant improvement in renal and cardiovascular (CV) outcomes. More importantly, the improvement in HF hospitalization (HHF) in the CV outcomes trials of SGLT-2is was striking. Multiple mechanisms have been proposed for the pleiotropic effects of SGLT-2is beyond their glycemic control. However, as patients with HF were not included in any of these trials, it can be considered as a primary intervention. Subsequently, two landmark studies of SGLT-2is in patients with HFrEF, namely, an empagliflozin outcome trial in patients with chronic HF and a reduced ejection fraction (EMPEROR-Reduced) and dapagliflozin and prevention of adverse outcomes in HF (DAPA-HF), demonstrated significant improvement in HHF and CV mortality regardless of the presence of DM. These impressive results pitchforked these drugs as class I indications in patients with HFrEF across major guidelines. Thereafter, empagliflozin outcome trial in patients with chronic HF with preserved ejection fraction (EMPEROR-Preserved) and dapagliflozin evaluation to improve the lives of patients with preserved ejection fraction HF (DELIVER) trials successively confirmed that SGLT-2is also benefit patients with HFpEF with or without DM. These results represent a watershed as they constitute the first clinically meaningful therapy for HFpEF in the past three decades of evolution of HF management. Emerging positive data for the use of SGLT-2is in acute HF and post-myocardial infarction scenarios have strengthened the pivotal role of these agents in the realm of HF. In a short span of time, these classes of drugs have captivated the entire scenario of HF.

BACKGROUND

The MANTA vascular closure device (VCD) represents a novel approach to achieving hemostasis after large-bore femoral access procedures. Numerous clinical studies have evaluated the efficacy of the MANTA device across a range of patient populations undergoing different procedures. However, there is still a paucity of data available concerning the use of MANTA devices in aiding the decannulation of venoarterial extracorporeal membrane oxygenation (VA-ECMO).

AIM

To present our single-center experience of utilizing the MANTA VCD in patients undergoing this procedure.

METHODS

This single-center study included all patients undergoing percutaneous decannulation of femoral VA-ECMO using the MANTA plug-based VCD between January 2021 and October 2023 at University Hospitals Cleveland Medical Center. Inclusion criteria were adult patients who required prolonged (> 24 hours) hemodynamic support with VA-ECMO. Outcomes included all-cause mortality, hemostasis, bleeding, limb ischemia, and site infection.

RESULTS

This is a retrospective cohort study of 19 patients with a mean age of 56.8 years. Twelve of them were males with a mean body mass index of 29. The most common extracorporeal membrane oxygenation indication was acute coronary syndrome complicated by cardiogenic shock at 36.8%. The mean length of intensive care unit stay for these patients was 18.8 ± 8.42 days. Seventeen out of 19 patients survived to discharge. The MANTA device was successfully deployed in 19 patients, with 10 procedures conducted at the bedside and 9 in an operating room setting. Complete hemostasis was achieved within 5 minutes of MANTA deployment in 17 out of 19 patients. In 2 patients manual compression after Manta deployment was required to achieve adequate hemostasis. Additionally, acute lower extremity ischemia was noted in two patients, necessitating endovascular interventions. No infections were reported at the site of MANTA deployment.

CONCLUSION

Overall, based on our experience and that of other centers, the MANTA VCD has proven to be a simple, safe, and effective percutaneous technique for facilitating in the OR, but most of all it opens the opportunity for bedside VA-ECMO decannulation. Post-decannulation ischemic complications are higher in this series of sick patients when compared with elective procedures like transcatheter aortic valve replacement and endovascular aneurysm repair. Additionally, operators should be mindful of the incidence of ischemic complications. Distal Doppler pulse signals should always be checked, to indicate bailout options when this occurs.

Plants in stressful environments tend to be more asymmetrical, have reduced defenses, and are more vulnerable to herbivory. Stressful conditions are also detrimental to free-living herbivorous insects, which are sensitive to climatic variations like extreme temperatures and dry periods. In the Cerrado, different phytophysiognomies range from open to closed and structurally complex areas, simulating a gradient of environmental harshness. This study examines the relationship between fluctuating asymmetry (FA) and herbivory in Qualea parviflora and Eugenia dysenterica across five Cerrado areas. We tested the Plant Stress Hypothesis (PSH) and the Environmental Harshness Hypothesis (EHH), investigating their interaction. Specifically, we assessed how stressful conditions influence plants, herbivory rates, and the richness and abundance of herbivorous insects, considering species composition variation among phytophysiognomies. Results showed significant differences in structural complexity among areas, with campo rupestre < cerrado sensu stricto < cerradão. FA per plant varied with increasing complexity for Q. parviflora but not for E. dysenterica. Leaf area removed differed between species but did not vary significantly with complexity. Leaf area removed decreased with increasing FA in Q. parviflora but increased with FA and complexity interaction in E. dysenterica. Contrary to predictions, free-living herbivore richness and abundance were higher in the most stressed phytophysiognomy, with species composition variation mainly influenced by the substitution process.

Published: October 2024

El estudio se desarrolló con el objetivo de analizar cómo la inadecuada aplicación del principio de equidad constitucional contribuye a la revictimización de las víctimas de violencia de género. Esto mediante la aplicación de un enfoque cualitativo y cuantitativo e implementación de 10 encuestas dirigidas a abogados/as en libre ejercicio del cantón Shushufindi y 3 entrevistas aplicadas a un juez y dos fiscales del mismo cantón. De la investigación se obtuvo como resultado que, el 90% de los participantes dicen conocer el principio de no revictimización, así también el 80% alude que es necesario que el este principio esté contenido en la normativa penal ecuatoriana. Los profesionales entrevistados por su parte mencionan que el tema de la revictimización es muy amplio y pese a los esfuerzos de garantizarlo en varios casos no se lo cumple. Además, se concluye que sería factible incorporar en el COIP el principio de no revictimización.

Published: October 2024

La recaudación tributaria es una tarea fundamental para el financiamiento del Estado, pero cuando los contribuyentes no con cumplen con dicha obligación el Servicio de Rentas Internas se ve forzado a iniciar el proceso de ejecución coactiva, es en esa instancia donde la falta de claridad y consistencia de la normativa tributaria se transforma en un problema tanto para el contribuyente como para la administración, pues queda a discrecionalidad de esta última actuaciones fundamentales como la disposición de medidas cautelares, mismas que pueden afectar derechos constitucionales del usuario. El estudio tiene como propósito primordial evaluar la efectividad de los procesos de ejecución coactiva sustanciados por el SRI en la protección del derecho a la propiedad y seguridad jurídica, para lo cual se aplicó el método mixto, a través de la implementación de encuestas a cien usuarios del sistema tributarios y entrevistas semiestructuradas a profesionales del Derecho. Tras el procesamiento de los datos se evidencia una postura de rechazo por parte de la población ante la actuación de los funcionarios ejecutores del proceso coactivo, pues la disposición desproporcionada de medidas como la retención o la prohibición de enajenar afectan significativamente sus derechos. Como conclusión se determina que la falta de claridad y armonización de la norma tributaria posibilita que los funcionarios públicos quebranten el principio de buena fe y rebasen con sus actuaciones los límites del derecho de propiedad y seguridad jurídica de los afiliados al sistema tributario.
THE INFLUENCE OF PROF. JOVAN CVIJIĆ’S RESEARCH IN GEOMORPHOLOGY IN FRANCE AND THE BALKANS: WHICH LEGACY?
Authors:   Sorbonne Université, UFR de Géographie et Aménagement, UR Médiations, France, Fouache Eric
Published: October 2024

Jovan Cvijić (1865–1927) was a physical geographer, which is only one aspect of his field of endeavor but the one I will focus on in this presentation. As such, he played a role in the development of this discipline at national and international levels. His personal qualities were crucial to this recognition, but the intellectual background of the second half of the 19th century and the transnational context of the Austro-Hungarian Empire facilitated this threefold development. With his thesis entitled Das “Karstphänomen” (“The Karst phenomena”), defended in Vienna in 1883, he succeeded in providing synthetic knowledge about the Karst and establishing a vocabulary and concepts (such as doline, uvala, polje) that have endured to this day. In Vienna, in contact with his professors, starting with Penck, he fully embraced a modern geography based on field observations as opposed to a cabinet geography, a geography that needed to be illustrated by drawing or photography. His physical geography hypotheses needed to be supported by solid naturalist and physical knowledge. It was in this spirit that he carried out his successive responsibilities in Serbia, both at the University of Belgrade and at the Geographical Society, and that he subsequently extended his research to other areas of physical geography: climatology, hydrology, impact of last glaciation, fluvial erosion, limnology, etc. His knowledge of the French, German and Serbian languages enabled him to exchange ideas with his peers throughout Europe (Penck, Tomaschek, Martel, De Martonne, De la Blache, etc.) and to develop his hypotheses in line with these exchanges. He also shared his work through courses abroad, most notably in Paris in 1917 and 1918, and through publications in international journals. Thus, he strengthened his academic authority at national and international levels. It is in the field of karstology that Cvijic’s work remains most up-to-date, and his approach to field work, his constant exchanges with his peers, his concern for international issues and the practice of open geography are the foundations of modern physical geography.

Malaria is an infectious disease caused by the Plasmodium parasite and transmitted through the bite of female Anopheles mosquitoes. Although global efforts to control the disease have increased, malaria remains a major health threat, especially in developing countries. This study aims to identify recent developments in malaria treatment methods. This study uses a narrative review method. Data collection was carried out through a literature review by searching for relevant research articles, reports, and books from various scientific databases. The collected data were then analyzed in three stages, namely data reduction, data presentation, and drawing conclusions. The results showed that updates in malaria treatment include the development of new drugs and combination therapies, prevention efforts through vaccines, more individualized treatment approaches, and community involvement in treatment programs. These initiatives provide new hope in the fight against malaria.
Environmentální úzkost a naděje optikou existenciální fenomenologie
Authors: Vičanová Gabriela , Vaškovic Petr
Published: October 2024

The study looks at environmental anxiety and hope from the perspective of existential philosophy, as two different forms of existential attunement. In the first part of the text, the current state of research in the field of environmental emotions and moods is sketched out. The concept of environmental anxiety is then briefly delineated, drawing on current taxonomies of environmental emotions as well as on philosophical definitions of anxiety promulgated by Kierkegaard, Heidegger, Tillich and contemporary existential phenomenologists. The existential relevance of environmental anxiety is subsequently defined with the help of an analysis of the experience of the loss of meaningfulness that accompanies environmental anxiety, and then also an analysis of the change in how the natural world reveals itself to the anxious individual. The second part of the study focuses on the mood of hope. The hope for a solution to the ecological crisis is often presented in both public discussion and in the professional literature in the form of new technologies, political will or Providence. This hope is made immediately available and without making any great demands on the hopeful individual. However, by means of Kierkegaard the study shows that this kind of hope is a kind of illusion that leaves a person in a state of inaction, and even becomes an obstacle to a more radical form of hope, one that is capable of inspiring the individual to act, for example, toward “an active solution to the ecological crisis.”
DIFFERENT PERSPECTIVE OF DARBOUX SLANT RULED SURFACES AND THEIR CONSTRUCTIONS VIA QUATERNIONS
Authors: KARACA EMEL , ALPAY ESRA
Published: October 2024

In this paper, based on the definition of Darboux slant ruled surface in R^3, a novel method for the Darboux slant ruled surface obtained from the striction curve of the natural lift curve is described in R^3. Then, an isomorphism between the unit dual sphere, 〖DS〗^2, and the subset of the unit 2-sphere, TM ̅ is used to define this surface. Hence, the striction curve of the natural lift curve is corresponded to Darboux slant ruled surface in R^3by considering the isomorphism. Additionally, some fundamental theorems are proved to characterize this surface. Using the quaternion product of the quaternionic operator and a pure unit quaternion, the quaternionic expression for the Darboux slant ruled surface is defined. In the last, 2-parameter homothetic motion is expressed for this surface.

ELEMENTAL ANALYSIS BY XRF OF COLOR SAMPLES USED BY GIORGIO DE CHIRICO SAMPLED IN THE MASTER'S ATELIER AT THE HOUSE MUSEUM LOCATED IN PIAZZA DI SPAGNA IN ROME
Authors: CAMPANELLI SIMONE , DE LEONE RENATO , ROSELLI GRAZIELLA
Published: October 2024

The aim of this paper is to analyze numerous materials utilized by the esteemed artist Giorgio de Chirico underwent analysis. These materials are housed in the House Museum of Piazza di Spagna in Rome, where the painter spent the last thirty years of his life, thanks to the resources provided by the Giorgio and Isa de Chirico Foundation. Besides samples of resins and oils, including both pure and mixed varieties, approximately one hundred samples of tube colors were extracted from various boxes used by de Chirico, which are displayed in the Maestro's Atelier. Concurrently, ten paintings, with nearly 220 analysis points (one for every five years spanning from the 1930s to the 1970s), located within the House Museum, underwent analysis as well. The main objective is to establish a correlation between the tube colors utilized by the Master and the colors present in his paintings, aiming to identify significant markers that could serve as references for questions regarding the authenticity of his works. Additionally, the study conducts an in-depth investigation into the artistic technique of the great master, who was known for his penchant for experimenting with personal formulations in utmost secrecy. Furthermore, this study aims to contribute to the analysis of color degradation on canvas exposed to specific environmental conditions, in contrast to the original color preserved within the tube. The intriguing findings that have emerged need to be further enriched in the future through additional comparative analyses on a broader range of paintings and extended to contemporary painters. This endeavor aims to establish a technical-scientific database of reference for scholars of 20th Century painting.

This study investigates the quality of ten different brands of bottled water purchased from various stores across Romania, using a comprehensive analysis of both physicochemical parameters and heavy metal content. The analyzed parameters include pH, total dissolved solids (TDS), dissolved oxygen, turbidity, free and total chlorine, and conductivity. Additionally, the concentration of various heavy metals was measured to assess compliance with current Romanian legislation and international water quality standards. Each water brand was subjected to eight repetitions of electroanalytical testing to ensure accuracy and consistency in the results. Furthermore, statistical analysis, including descriptive analysis, Pearson correlation, and Principal Component Analysis (PCA), was employed to identify key interdependencies both among the physicochemical parameters and between the identified heavy metals. This multifaceted approach offers a deeper understanding of the overall quality of bottled water available in Romania and highlights potential risks related to heavy metal contamination.

The main objective of this study was the archaeometric analysis of eleven ceramic fragments discovered in the archaeological site of Suplacu de Barcău/Porț-Corău, situated in the Northwest part of Romania, more precisely in the Sylvanian Basin. The ceramic fragments come from different archaeological contexts and show a typically decoration, through black painting. The studied ceramic fragments have fine and semi-fine textures, discovered in certain stratigraphic situations: funerary contexts or household pits. All the analysed fragments belong to the Suplac type pottery. The archaeological research, both systematic and preventive, highlighted the main characteristics of the Neolithic habitation in the Sylvanian Basin, making it the subject of numerous studies until now. In the present paper, optical microscopy, scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) analyses were carried out on the batch of ceramic pieces studied, and based on the obtained results, the burning temperature of the samples was estimated. At the same time, for five clay samples – collected from archaeological sites and around the settlement – the elemental content was determined to establish the potential source of clay for the ceramic fragments.

This study aims to determine the concentrations of heavy metals and other metals of safety concern in citrus fruit peel extracts. Different types of citrus fruits (i.e., lemon, mandarin, orange, grapefruit, and lime) were collected randomly from markets, during the spring of the year 2024. The inductively coupled plasma mass spectrometry technique was used to determine the concentrations of Al, Cr, Mn, Ni, Cu, Zn, Sr, Cd, and Pb in citrus peel extracts. The obtained data have not exceeded the maximum allowed limits provided by European legislation. The statistical analysis results show that Cu and Zn were correlated positively. Likewise, a strong positive correlation (>0.500) can be observed between Al and Sr, Cr and Ni, Cr and Zn, Cr and Pb, Mn and Zn, Ni and Cd, Ni and Pb, Cd, and Pb. To check if the sample data are adequate, the Kaiser-Meyer-Olkin test was used. The principal component analysis contains a maximum of three components responsible for 74.872% of the total variation, while cluster analysis revealed the approximate HMs content of the 17 analyzed samples.

Published: October 2024

This paper presents the hydration kinetics of a CEM II/B-M type Portland composite cement by DTA/TGA analyses and mathematical and software modeling prediction. The reason for this choice is generated by its use as the main binder in the concrete matrix used for radioactive waste conditioning processes and the lack of public information related to its hydration process. The comparison between the experimental and modeling results indicated a good agreement and correlation of the results, reinforcing the idea that modeling can be a powerful tool that can be used in understanding this complex multicomponent-multiphase system of hydrated cement and can facilitate the assessment of the geochemical evolution of cement-based materials under different environmental conditions.
