This was done to ascertain if they met the minimum required standard for human consumption. They were purchased and labeled E, F and I and were subjected to physicochemical and microbial tests. The parameters evaluated were TDS (Total dissolved solids), pH, Chloride, DO (Dissolved oxygen), Turbidity, Electrical conductivity (EC), Potassium, Calcium, Magnesium, Iron, Lead, Cadmium and Zinc. Their TDS ranged from 0.154 to 0.693 mg/L; pH ranged from 6.8 to 8.0; Cl- concentrations ranged from 5 to 10 mg/L; DO ranged from 5.4 to 6.5 mg/L; Turbidity ranged from 0.0 to 0.2 NTU and EC ranged from 0.330 to 0.451μS/cm. They were all within the limits stipulated by the considered standards. Their essential nutrient (K, Ca, Mg and Fe) contents were significantly less than the limits stipulated by the standards. Toxic heavy metals of Pb and Cd were below detectable limits. Total coliform count and SO42- concentrations were also zero. They had poor values of EC and very poor concentrations of essential nutrients. It was therefore recommended that there should be an improvement on the ratio of all the essential nutrients in the studied sachet water products to positively enhance the health of their users.

Each substrate was physico-chemically pretreated with water, 1% NaOH, 1% KOH, 1% Ca(OH)2, 1% H2SO4 1% HCl and 1% HNO3 in order to identify the reagent that has the best hydrolytic effect. Thereafter, the concentration of the identified reagents with the best hydrolytic effects in each case was scaled up to 2% and 3% reagent concentrations in order to identify the optimum concentration for optimal bioethanol yield. Simultaneous Saccharification and Co-fermentation strategy using Trichoderma ressi, P. stipitis and S. cerevisiae inoculums were adopted under aseptic condition. It was found that the amount of sugars liberated depended on the type of chemical reagent utilized during physico-chemical pretreatment. The substrates seemed to be chemically selective; however, 1% NaOH, 1% H2SO4 and 1% HCl gave the best hydrolytic results. It was also found that mild pretreatment conditions were necessary for optimum bioethanol yield. Bioethanol production and yield took place optimally in samples physico-chemically pretreated with 1% reagent concentration when compared with 2% and 3% reagent concentrations.

Prostaglandin-based Lutalyse® (PGF2α) hormone was injected intramuscularly at a dose of 2.5 ml in a single shot to synchronise oestrus in sixty does. Does and chosen bucks were mate at random with a 1:10 buck to doe ratio right after the hormone treatment. The expression of standing heat when does were exposed to bucks was used to determine the oestrous response to hormone treatment. Within 96 hours, the does that displayed oestrus were allowed with bucks. Pregtone® was used to diagnose the pregnancy one month later, or it was done by visual observation. Approximately 85% of the does exhibited oestrus within 56 hours of hormone delivery, according to the results. The Pregtone® tool demonstrated high efficacy in detecting early pregnancy prior to hormone delivery. The observed rate of abortion was 6.12%, but the overall conception rate was 81.7%. In does, the gestation duration was 153±2.56 days on average. The synchronised does' kid had an average birth weight of 2.49±0.33 kg and a litter size of 1.31±0.46, respectively. While body weight and district had no effect on the oestrous response and conception rate, the does' age, parity, and body condition did (p<0.05). The oestrus response and conception rate of does with a parity of 1 to 4 were considerably higher than those of does with a parity of five. When it came to hormone treatment and conception rate, the does with body condition scores of 3 and 4 responded better than those with lower scores. Compared to younger does, older did displayed a reduced oestrus response and conception rate. It was discovered that taking age, parity, and body condition score into account during oestrus synchronisation in local goats was helpful for a higher conception rate.

To find breaches in the cloud computing environment, researchers have surveyed a number of intrusion detection methods. The majority of them discuss conventional abuse and anomaly detection methods. By positioning the analysing component outside the virtual machine, usually at the hypervisor, Virtual Machine Introspection techniques are highly useful in identifying various stealth attacks that target user-level and kernel-level processes operating in VMs. Techniques such as Hypervisor Introspection protect the hypervisor and stop a compromised hypervisor from attacking virtual machines that run on it. Through the use of hardware-assisted used in virtualization-enabled technologies, introspection approaches examine the hypervisor. Our paper's primary goal is to present a thorough literature review of the many intrusion detection methods that have been suggested for cloud environments, along with an evaluation of their capacity to detect attacks. To clarify the vulnerabilities in the cloud, we offer a threat model and attack taxonomy. Our taxonomy of IDS techniques offers a thorough analysis of approaches together with their distinguishing characteristics, and it represents the state of the art in classification. In the survey, we have given a thorough understanding of methods based on Virtual Machine Introspection and Hypervisor Introspection. With the help of our study, researchers should be able to start investigating intrusion detection techniques in cloud environments.

The diversity of gut microbes evolves throughout an individual's lifetime, with disturbances and alterations linked to metabolic diseases such as obesity and type 2 diabetes. The gut comprises approximately 100 million neurons, more than the human spinal cord, and is often referred to as the "second brain." Emerging research highlights a bidirectional communication between the gut and the brain through multiple mechanisms, including neural, immune, and endocrine pathways. While scientists have extensively explored the role of nutrition and probiotics in gut health, the independent effects of exercise on the gut microbiome and gut-brain axis remain under-researched. This review aims to examine the gut microbiome, its intricate connections, and the influence of exercise in modulating gut microbial composition, thereby improving host physiology. Additionally, it investigates the impact of physical activity on the gut-brain axis, particularly in relation to mood and behavioral disorders. Given the increasing burden of chronic diseases and mental health disorders, understanding the exercise-gut interaction offers valuable insights for public health strategies focused on disease prevention, mental well-being, and holistic health promotion.

Despite over 2.5 million wholesale and retail trade establishments, VAT registration among traders is only 2.8%, contributing a mere 1.5% of total VAT revenue. This study examines the challenges, compliance gaps, and enforcement issues affecting trade VAT in Bangladesh. The findings highlight complex registration processes, lack of awareness, informal business structures, and limited digital integration as major barriers. While initiatives such as Electronic Fiscal Devices (EFDs) and online VAT filing systems have been introduced, their adoption remains slow. The study recommends simplified VAT models for small traders, expanded digital infrastructure, stronger enforcement mechanisms, and targeted awareness programs to enhance compliance. Strengthening VAT at the trading stage can significantly increase revenue collection, improve tax transparency, and support economic growth.

Using a sample of firms from the CSMAR database, we investigate how different forms of debt financing short-term debt, long-term debt, and total debt affect firm performance metrics, specifically Return on Equity (ROE) and Return on Assets (ROA). To mitigate potential biases in traditional regression models, we employ Generalized Two-Stage Least Squares (G2SLS) and instrumental variable (IV) techniques. Our results show that long-term debt (LTDTA) and total debt to total assets (TDTA) have significant effects on firm performance, with some mixed relationships observed between debt financing variables and performance outcomes. The study further addresses issues of collinearity and endogeneity, demonstrating that the use of robust standard errors and instrumental variables provides more reliable estimates. The findings highlight the importance of strategic debt management for firms aiming to optimize performance while minimizing risks associated with excessive leverage. This study contributes to the literature on capital structure and firm performance, offering implications for financial managers, investors, and policymakers. Future research could extend these findings by exploring the effects of other financing sources and firm-specific characteristics across different industries.

However, the literature lacks studies on dengue-related hospitalizations in Pará, which could support more effective health policies for controlling and reducing the disease in the state. Objectives: To evaluate the temporal trend and compare dengue hospitalizations in Pará with other states in the Northern Region, outlining the epidemiological profile. Methods: This is a descriptive ecological epidemiological study using data from the Hospital Information System (SIH) from 2014 to 2023, referring to hospitalizations due to dengue (ICD C32.1). The analyzed variables included year and month of care, number of hospitalizations, hospitalization rate per 100,000 inhabitants, sex, age, and type of care. Statistical analysis was performed using Simple Linear Regression, the Kruskal-Wallis test, and Dunn’s post-hoc test, using Statistics Kingdom software. Results: A total of 13,956 hospitalizations for dengue were recorded in Pará during the study period. A reduction trend of 2.88 hospitalizations per year was observed (p < 0.005, B1 = -2.88, 95% CI [-4.62, -1.14], R = -0.80). The Kruskal-Wallis test, followed by Dunn’s post-hoc test, showed that Pará did not present a significantly different hospitalization rate compared to the other states. In the epidemiological profile, females had a higher number of hospitalizations (n=7,201) compared to males (n=6,755). The adult hospitalization rate was 4.7 times higher than that of the elderly and 1.6 times higher than that of children and adolescents. Additionally, 92.9% of hospitalizations occurred on an emergency basis. Conclusion: Pará has shown a reduction in hospitalizations due to dengue over the years. Women and adults are the most affected, with the majority of hospitalizations occurring on an emergency basis. The results suggest that this decrease may be due to more effective preventive strategies, underreporting of cases, or reduced exposure to risk factors among the population of Pará. Future studies are needed to confirm these hypotheses and guide more targeted interventions.

Resilient cultivators are able to maintain, and even grow, their livelihoods, despite these pressures. Increasing the resilience of seaweed farmers contributes to the prevention and alleviation of poverty. The aim of this research is to determine the status of sustainability of seaweed cultivation livelihoods in Nain Island, North Sulawesi Province, Indonesia. Based on the results of the Rapfish analysis, a sustainability index was obtained for the economic and institutional dimensions with unsustainable status, for the socio-cultural dimension less sustainable, and the technological dimension with moderately sustainable status. Sensitive attributes that influence 9 of the 16 attributes. For the economic dimension, sensitive factors are market chain, marketing and acceptance. In the socio-cultural dimension, sensitive attributes are family participation and other businesses. In the technological dimension, the attributes that influence or need to be intervened in the sustainability status of seaweed cultivation businesses are the availability of industry and the availability of clotheslines. And in the institutional dimension, the influential attributes are the extension center and the origin of capital. The results of the sustainability index analysis for each dimension of seaweed cultivation activities on Nain Island are included in the less sustainable category at this time. The results of research regarding the ecological conditions in seaweed cultivation on Nain Island are in accordance with the existing theory that the suitable season for cultivation is the dry season. Then, regarding the availability of the seeds themselves, they are always available with medium quality seeds, because the seeds are used repeatedly. The average depth of water for farmers' cultivation is 6.27, based on theory, this depth is suitable for seaweed cultivation activities.

The objective was to determine the stage of Stylosanthes humilis (Kunth) should be harvested in order to maximize dry matter and provide higher-quality hay. The six treatments were before to flowering (BF), 10, 25, 50, 75, and 100% flowering stages were tested for yield and nutritional quality using a randomized complete block design with three replications. The findings demonstrated that the evaluated morphological features and quality indicators had different interaction effects. Hay harvested at 10% flowering stage had the highest leaf proportion, and the CP content varied significantly (p<0.01) between treatments; hay harvested at 10% flowering stage had a higher IVDMD value (66.9%), while hay harvested before flowering had a higher value (20.9, 20.8, and 20.6%, respectively). Plant height had a negative correlation with LSR, CP, ash, NDF, ADF, and IVDMD, but a positive and significant (P<0.001) correlation with DM% and dry matter yield t/ha. NDF was uncorrelated with LSR, DMY t/ha, and IVDMD, while it was positively and significantly correlated (p<0.001) with ADF and DM% and negatively connected with CP. Determine that the 25% flowering stage was the best time to harvest Stylosanthes humilis (Kunth) hay, leading to a higher dry matter yield and better nutrient quality. This was highly advised in order to improve the usage of Stylosanthes humilis (Kunth) hay in farmers' technological demonstrations.

Despite over 2.5 million wholesale and retail trade establishments, VAT registration among traders is only 2.8%, contributing a mere 1.5% of total VAT revenue. This study examines the challenges, compliance gaps, and enforcement issues affecting trade VAT in Bangladesh. The findings highlight complex registration processes, lack of awareness, informal business structures, and limited digital integration as major barriers. While initiatives such as Electronic Fiscal Devices (EFDs) and online VAT filing systems have been introduced, their adoption remains slow. The study recommends simplified VAT models for small traders, expanded digital infrastructure, stronger enforcement mechanisms, and targeted awareness programs to enhance compliance. Strengthening VAT at the trading stage can significantly increase revenue collection, improve tax transparency, and support economic growth.

Using a sample of firms from the CSMAR database, we investigate how different forms of debt financing short-term debt, long-term debt, and total debt affect firm performance metrics, specifically Return on Equity (ROE) and Return on Assets (ROA). To mitigate potential biases in traditional regression models, we employ Generalized Two-Stage Least Squares (G2SLS) and instrumental variable (IV) techniques. Our results show that long-term debt (LTDTA) and total debt to total assets (TDTA) have significant effects on firm performance, with some mixed relationships observed between debt financing variables and performance outcomes. The study further addresses issues of collinearity and endogeneity, demonstrating that the use of robust standard errors and instrumental variables provides more reliable estimates. The findings highlight the importance of strategic debt management for firms aiming to optimize performance while minimizing risks associated with excessive leverage. This study contributes to the literature on capital structure and firm performance, offering implications for financial managers, investors, and policymakers. Future research could extend these findings by exploring the effects of other financing sources and firm-specific characteristics across different industries.

However, the literature lacks studies on dengue-related hospitalizations in Pará, which could support more effective health policies for controlling and reducing the disease in the state. Objectives: To evaluate the temporal trend and compare dengue hospitalizations in Pará with other states in the Northern Region, outlining the epidemiological profile. Methods: This is a descriptive ecological epidemiological study using data from the Hospital Information System (SIH) from 2014 to 2023, referring to hospitalizations due to dengue (ICD C32.1). The analyzed variables included year and month of care, number of hospitalizations, hospitalization rate per 100,000 inhabitants, sex, age, and type of care. Statistical analysis was performed using Simple Linear Regression, the Kruskal-Wallis test, and Dunn’s post-hoc test, using Statistics Kingdom software. Results: A total of 13,956 hospitalizations for dengue were recorded in Pará during the study period. A reduction trend of 2.88 hospitalizations per year was observed (p < 0.005, B1 = -2.88, 95% CI [-4.62, -1.14], R = -0.80). The Kruskal-Wallis test, followed by Dunn’s post-hoc test, showed that Pará did not present a significantly different hospitalization rate compared to the other states. In the epidemiological profile, females had a higher number of hospitalizations (n=7,201) compared to males (n=6,755). The adult hospitalization rate was 4.7 times higher than that of the elderly and 1.6 times higher than that of children and adolescents. Additionally, 92.9% of hospitalizations occurred on an emergency basis. Conclusion: Pará has shown a reduction in hospitalizations due to dengue over the years. Women and adults are the most affected, with the majority of hospitalizations occurring on an emergency basis. The results suggest that this decrease may be due to more effective preventive strategies, underreporting of cases, or reduced exposure to risk factors among the population of Pará. Future studies are needed to confirm these hypotheses and guide more targeted interventions.

Resilient cultivators are able to maintain, and even grow, their livelihoods, despite these pressures. Increasing the resilience of seaweed farmers contributes to the prevention and alleviation of poverty. The aim of this research is to determine the status of sustainability of seaweed cultivation livelihoods in Nain Island, North Sulawesi Province, Indonesia. Based on the results of the Rapfish analysis, a sustainability index was obtained for the economic and institutional dimensions with unsustainable status, for the socio-cultural dimension less sustainable, and the technological dimension with moderately sustainable status. Sensitive attributes that influence 9 of the 16 attributes. For the economic dimension, sensitive factors are market chain, marketing and acceptance. In the socio-cultural dimension, sensitive attributes are family participation and other businesses. In the technological dimension, the attributes that influence or need to be intervened in the sustainability status of seaweed cultivation businesses are the availability of industry and the availability of clotheslines. And in the institutional dimension, the influential attributes are the extension center and the origin of capital. The results of the sustainability index analysis for each dimension of seaweed cultivation activities on Nain Island are included in the less sustainable category at this time. The results of research regarding the ecological conditions in seaweed cultivation on Nain Island are in accordance with the existing theory that the suitable season for cultivation is the dry season. Then, regarding the availability of the seeds themselves, they are always available with medium quality seeds, because the seeds are used repeatedly. The average depth of water for farmers' cultivation is 6.27, based on theory, this depth is suitable for seaweed cultivation activities.

The objective was to determine the stage of Stylosanthes humilis (Kunth) should be harvested in order to maximize dry matter and provide higher-quality hay. The six treatments were before to flowering (BF), 10, 25, 50, 75, and 100% flowering stages were tested for yield and nutritional quality using a randomized complete block design with three replications. The findings demonstrated that the evaluated morphological features and quality indicators had different interaction effects. Hay harvested at 10% flowering stage had the highest leaf proportion, and the CP content varied significantly (p<0.01) between treatments; hay harvested at 10% flowering stage had a higher IVDMD value (66.9%), while hay harvested before flowering had a higher value (20.9, 20.8, and 20.6%, respectively). Plant height had a negative correlation with LSR, CP, ash, NDF, ADF, and IVDMD, but a positive and significant (P<0.001) correlation with DM% and dry matter yield t/ha. NDF was uncorrelated with LSR, DMY t/ha, and IVDMD, while it was positively and significantly correlated (p<0.001) with ADF and DM% and negatively connected with CP. Determine that the 25% flowering stage was the best time to harvest Stylosanthes humilis (Kunth) hay, leading to a higher dry matter yield and better nutrient quality. This was highly advised in order to improve the usage of Stylosanthes humilis (Kunth) hay in farmers' technological demonstrations.

It is a magical and playful moment, told and narrated during the bean threshing, awakening the awareness of aspects related to the care for life and the environment, while establishing the feelings of collectivity, union, and collective organization, making these moments a process of struggle and resistance to keep their traditions alive. Thus, the present study aims to analyze how the ancestral knowledge perpetuated in storytelling contributes to the processes of struggle and resistance of the Fernanda Ielpo da Cunha et al.
