Background: Exhaust noise is known to be a major pollutant in the environment and workplaces due to the development of industry and transportation. Exhaust noise can be reduced to normal levels by mufflers or silencers. A reactive muffler efficiently dampens noise at low frequencies by reflecting sound waves. Therefore, muffler design is of great importance in exhaust noise reduction. Transmission loss (TL) is an essential characteristic of mufflers, demonstrating their acoustical properties. Any acoustical appliance is selected based on its damping performance and reliability. Predicting TL through experimentation is different from theoretical calculations. Methods: In the present study, a double-expansion chamber muffler was designed as a reflective muffler on a laboratory scale by equations. Next, TL was evaluated by an impedance tube applying a 4-microphone technique to determine the acoustical performance of the designed muffler. Results: Findings revealed that the TL of the muffler at 312 Hz frequency obtained 27.5 dB agreement with the required TL of the muffler of 25 dB. In addition, the TL of the muffler against frequency attenuates noise in broadband frequencies. Conclusions: These results indicated that the built muffler provides desired TL for exhaust chambers. Therefore, equations can be used as a precise method for muffler design. Furthermore, multi-expansion chamber mufflers are useful for reducing noise at a wide range of frequencies.

Introduction: Psilocybin mushroom use is well documented in spiritual and religious ceremonies globally. This drug is now the most popular in Europe and the USA. Objective: The objective of this study is to explore the experiences and effects of psilocybin on patients with depression and anxiety. Method: A qualitative study was conducted interviewing ten participants currently taking psilocybin while experiencing depression and/or anxiety. Ethical approval was obtained from the University ethics committee. Participants were recruited via social media and groups are known to have used psilocybin for the treatment of anxiety and/or depression. Participants were informed of study aims and consent was obtained before interviews commenced. Confidentiality was maintained throughout this study. Interviews began with informing participants that psilocybin may be effective in the management of depression. Initially, information around the way treatment with psilocybin was obtained was sought. This was followed by queries around the effects of the drug in terms of experiences both during and after treatment. Finally, participants were asked to outline the positive effects of psilocybin on their lives. Results: The data were thematically coded using Grounded Theory as an underpinning philosophical paradigm. Emerging themes included enhancement of smell, vision, hearing, and taste sensations. Another theme emerging was the experience of being ‘connected with the universe’ while on the drug. Additionally, participants reported a stabilization of mood, an increase in optimism and emotional control, and a healthier emotional connection with others. Most also felt an increase in comfort, peace and calmness. Another theme that emerged centered on the mechanism of action of psilocybin. Participants stated that this substance seemed to ‘make new connections in their brain,’ resulting in new perspectives. Some participants felt this resulted in a calming influence on the mind and body. This aligns with research showing that psilocybin works by changing the thinking and improving information processing. Conclusion: Psilocybin has promising effects on the patients with depression/anxiety even after a single dose. Psilocybin is safe but the administration should be guided by a health professional to yield safe and positive outcomes.

Venous thromboembolism (VTE) is a serious medical condition that has a high clinical burden on both the mother and fetus, despite having a low incidence during pregnancy and the postpartum period. VTE is a leading cause of death among pregnant women and new mothers worldwide, and its severity cannot be underestimated. The development of VTE is influenced by a combination of genetic and environmental factors, as well as acquired conditions. Pregnancy-related changes, such as increased levels of coagulation factors and diminished fibrinolysis, can increase the risk of VTE. Additionally, older mothers, those who are obese, multiparous, or have undergone cesarean delivery, are at a higher risk of developing VTE. Owing to the lack of standardized guidelines and reliable data on VTE prevention, diagnosis, and treatment, authorities have developed risk scores that allow for a personalized assessment of the risk of thrombosis during pregnancy and postpartum, enabling a tailored approach to prevent thrombosis. Managing VTE during pregnancy poses significant challenges because the benefits and risks of anticoagulant treatment for both the mother and fetus must be carefully balanced. An interdisciplinary approach that includes obstetricians, neonatologists, physicians, and hematologists is essential to achieving optimal outcomes. This review explored the VTE updates in pathogenesis, presentation, complications, treatment options, and research gaps with proposal strategies to improve VTE outcomes and suggest further research.

In the modern world, Tuberculosis (TB) is regarded as a serious health issue with a high rate of mortality. TB can be cured completely by early diagnosis. For achieving this, one tool utilized is CXR (Chest X-rays) which is used to screen active TB. An enhanced deep learning (DL) model is implemented for automatic Tuberculosis detection. This work undergoes the phases like preprocessing, segmentation, feature extraction, and optimized classification. Initially, the CXR image is preprocessed and segmented using AFCM (Adaptive Fuzzy C means) clustering. Then, feature extraction and several features are extracted. Finally, these features are given to the DL classifier Deep Belief Network (DBN). To improve the classification accuracy and to optimize the DBN, a metaheuristic optimization Adaptive Monarch butterfly optimization (AMBO) algorithm is used. Here, the Deep Belief Network with Adaptive Monarch butterfly optimization (DBN-AMBO) is used for enhancing the accuracy, reducing the error function, and optimizing weighting parameters. The overall implementation is carried out on the Python platform. The overall performance evaluations of the DBN-AMBO were carried out on MC and SC datasets and compared over the other approaches on the basis of certain metrics.

This study intends to describe assessment strategies for young students' online learning. The participants in this descriptive qualitative study were 15 primary school principals and 35 teachers teaching Years 4 and 5 in urban and rural schools on the island of Lombok, West Nusa Tenggara Province, who volunteered their participation after undergoing comparable procedures. Using operational concepts of assessment of learning for online learning, class observation, and interview were organized. The content and structure validity of the measures were evaluated in accordance with the developmental periods of young learners. The findings showed that the teachers assessed the primary students' cognitive, psychomotor, and affective domains interactively during the online class meetings, in their portfolio, and through attitude direct observation. Several assessment strategies were advocated to circumvent the shortcomings of online learning. A criterion-referenced evaluation was used to conduct the analysis. The theoretical implications of the findings suggest that the various assessment procedures adopted have decreased the negative washback of online exams; however, further research is required to determine the consistency of the outcomes of online tests with other types of evaluation.

L’émergence des territoires et l’épuisement des saltus stimulent des questions foncières longtemps restées en veilleuse. Au T ogo en général et spécifiquement dans l’Ouest de la Région des Savanes, la terre est une propriété privée des lignages. Le droit foncier y repose sur la prééminence du droit du premier occupant et matérialisé par une divinité appelée Tingban. L’insuffisance des preuves de prééminence et l’authenticité des fétiches, source de droit, opposent souvent les collectivités. La présente étude décrit l’épuisement des ressources foncières et analyse les conflits fonciers qui opposent les collectivités dans l’Ouest de la Région des Savanes. La méthodologie adoptée repose sur l’observation participante, la recherche documentaire et les entretiens. Les résultats révèlent de nombreuses disputes socio-foncières qui opposent les lignages, les villages et les cantons. Les collectivités contestent entre elles, les droits de paternité sur les terres dans 74% des cas alors que 26% des querelles foncières sont dus aux remises en cause des limites des propriétés collectives. Ces contestations plongent leurs racines dans la complexité du droit foncier coutumier fondé sur la prééminence du droit du premier occupant. Elles sont aussi liées à la non maîtrise des limites des domaines fonciers lignagers et des territoires cantonaux respectivement par les descendants, les chefs de villages et les chefs de cantons.

Parkinson’s disease, first described by James Parkinson in 1817, is a neurodegenerative ailment resulting from the damage of nerve cells in the brain. It is a chronic, progressive, neurodegenerative disorder with an estimated prevalence of 31 to 328 per 100,000 people worldwide. It is estimated that more than 1 percent of the population over age 65 are afflicted with Parkinson’s disease; incidence and prevalence increase with age. There are numerous unanswered questions regarding the diagnosis and management of Parkinson’s disease. Worsening mobility, causing problems with activities of daily living, pain and communication problems due to rigidity of facial muscles, are the main reasons of their decreasing quality of life. This study is focused on the role of psychological variables, which could be associated with quality of life in PD patients. After their identification a discussion about opportunities of improvement patient’s quality of life can be opened. Current drug therapies for human PD with Levodopa or various dopamine receptor agonists offer symptomatic relief and appear to have little effect on the neurodegenerative process. More than 50% of patients with PD treated over 5 years with Levodopa will develop complications such as motor fluctuations and dyskinesia’s. In this scenario, slowing the progression of PD through neuroprotective or restorative therapy is a major focus of research. From a pharmacologic standpoint, current strategies involve interrupting the cascade of biochemical events that leads to death of dopaminergic cells. The significance of many indigenous medicinal plants and their phytoconstitutents in the management of Parkinsonism with minimal side effect profile arise in this context

This research work aimed to evaluate the effects of thermal processing treatments on the nutrient anti-nutrient composition of Afzelia africana (Akparata) flour. The seeds were sorted, cleaned and processed into boiled, roasted and autoclaved lima bean flours. The flours obtained were analysed for proximate, vitamin and anti-nutrient contents using standard methods. The proximate composition of the samples revealed that the flours had a range of moisture, 8.23-12.40%, crude protein, 15.98-25.95%, fat, 21.00-28.21%, ash, 1.34-2.89%, crude fibre, 2.00-3.45%, carbohydrate, 38.68-49.33%, and energy 424.13 – 482.37kJ/100g, respectively. The vitamin contents of the flours showed that the samples contained 0.02±0.00 - 0.08±0.00mg/100g riboflavin, 0.78 - 1.98 mg/100g niacin, 0.40 - 0.89 mg/100g thiamine, 120.40-234.70mg/100g vitamin A, 72.11-134.19mg/100g ascorbic acid, 09.67-17.65mg/100g vitamin E, 310.60-430.60mg/100g B6, 3.47-5.87mg/100g B12, respectively. The result of the anti-nutrient composition of the flours also showed that the phytate, tannin, oxalate, cyanogenic glycosides, protease inhibitors, haemagglutinins inhibitors, levels of the samples were significantly (p<0.05) reduced by roasting and boiling treatments compared to the sample processed by autoclaving. In addition, the saponin content of the flours was relatively higher in boiled sample than in roasted and autoclaved flours. However, the nutrient and anti-nutrient contents of the flours observed that the flours have the potentials to be used as nutritional supplements in the preparation of a variety of food products than the raw sample.

In the present study nanoparticles of lomustine were fabricated using chitosan polymer crosslinked with different crosslinking agents like sodium tripolyphosphate and sodium hexametaphosphate. Different formulations of nanoparticles were prepared using different concentrations of crosslinking agents and polyethylene glycol 6000. The average particle size ranged between 112 nm to 942 nm. Zeta potential of nanoparticles ranged between 29.0 mV up to 56.0 mV. Encapsulation efficiency was variable from 58%-96%. The nanoparticles were solid spherical. In vitro drug release study was carried out in phosphate buffered saline solution pH 7.4 for 10 h. The analysis of regression values of Higuchi plot suggested diffusional mechanism and follows Fick's law of diffusion. Drug polymer interaction was absent as evidenced by FT-IR spectra and DSC thermograms. With polyethylene glycol inclusion shows interaction between lomustine and PEG. Cell viability assay (MTT Assay) showed that the lomustine nanoparticles were able to reduce the tumour cell proliferation and increased cell viability significantly (p< 0.05) as compared to pure drug in L 132 human lung cancer cell line

The aim of this work was to prepare chitosan nanoparticles loaded with antineoplastic drug Lomustine (LCNPs), by ionic-gelation method with homogenization. The nanoparticles were characterized for particle size, polydispersity index (PDI), surface morphology, encapsulation efficiency, in-vitro drug release and cytotoxicity on human lung cancer cell line L132 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The particle size, zeta potential and encapsulation efficiency of prepared nanoparticles ranged from 75±1.1 to 637±1.6 nm (PDI from 0.05±0.001 to 0.18±0.007), 37.2±0.21 to 53.8±0.18 mV and 66.74±1.4 to 98.0±1.8% re- spectively. The particles were spherical in shape with smooth surface in scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images. Mechanical shearing by homogenization treatment significantly changed the nanoparticle size. The drug release rate was biphasic and diffusion controlled over the 8 h. LCNPs greatly inhibited the growth of the L132 cancer cell line used in this study in comparison to the native Lomustine (LMT).
