Abstract The study aimed to determine the ability of cardamom oil to preserve salmon. Cardamom essential oil is recovered from fresh cardamom by steam distillation. Essential oil is yellow, and transparent, hot spicy taste and characteristic aroma. Salmon is rich in components such as proteins, lipids, vitamins, minerals, etc., so it is a favorable environment for microorganisms to grow and develop. The study conducted experiments to preserve fresh salmon with cardamom essential oil with the content of 0.3%, 06%, and 0.9% at the temperature of 10 oC. The study has determined the biochemical, microbiological, and organoleptic criteria of fresh salmon in the formulas after 2 days, 4 days, and 6 days of storage. Finally, the cardamom oil content of 0.6% was selected to develop the preservation process. Salmon after preservation has a natural bright yellow color, good elasticity, and no viscosity; has a natural smell mixed with the characteristic aroma of cardamom essential oil; Salmon broth is clear, and has a characteristic sweet taste and characteristic aroma. The biochemical indicators: water, protein, lipid, vitamins, and minerals did not change significantly compared to the original; did not detect the presence of microorganisms strains Coliforms, Escherichia coli, Clostridium perfringens, Staphylococcus aureus, and Salmonella in preserved salmon.

ABSTRACT Introduction: Rabies is a viral disease that can be transmitted from animals to humans. All warm-blooded animals, including humans, can host rabies’s virus. Vaccination of dogs is an effective method of preventing rabies in humans. Objectives: To evaluate knowledge, attitudes and practices towards rabies prevention and factors related to vaccines for both patients exposed with rabies and dogs. Methods: A cross-sectional descriptive study, using the questionnaire on rabies prevention by interviewing 1 484 households. Multivariable logistic regression analysis was used to identify factors related to vaccines for both patients exposed to rabies and dogs. Results: Of all 67.32 % of the people surveyed with high knowledge, only 43.8 % and 31.47 % were assessed as having a good attitude and practice. Interviewees with poor knowledge and practice are independently related to low-rate vaccines provision for pets. Factors associated with low vaccination rates after pet bites were poor attitudes and practices. Conclusion: People with a high level of education, knowledge and practice, the rabies vaccination rate on pets is high. People with good attitudes and practices had a high rate of rabies vaccination after being bitten by an animal.

RESUMEN Introducción: La rabia es una enfermedad viral que puede transmitirse de animales a humanos. Todos los animales de sangre caliente, incluidos los humanos, pueden albergar el virus de la rabia. La vacunación de perros es un método eficaz para prevenir la rabia en humanos. Objetivos: Evaluar conocimientos, actitudes y prácticas de la comunidad hacia la prevención de la rabia y los factores relacionados con las vacunas, tanto para pacientes expuestos como para perros. Métodos: Estudio descriptivo transversal, se utilizó un cuestionario sobre prevención de la rabia, mediante entrevistas en 1 484 hogares. Se realizó un análisis de regresión logística multivariable para identificar los factores relacionados con las vacunas, tanto para pacientes expuestos como para los perros. Resultados: Del 67,32 % de encuestados, con alto conocimiento, solo el 43,8 % y el 31,47 % fueron evaluados como de buena actitud y práctica. Los entrevistados con insuficiente conocimiento y prácticas se relacionan de forma independiente con la baja provisión de vacunas para las mascotas. Las razones de bajas tasas de vacunación después de las mordeduras causadas por mascotas fueron las malas actitudes y prácticas. Conclusión: Las personas con nivel alto de práctica, educación y conocimientos, tienen elevados niveles de vacunación antirrábica de sus mascotas. Después de la mordedura de un animal, las personas con buenas prácticas y actitudes, tienen más altos niveles de vacunación antirrábica.

Abstract In this paper, free vibration analysis of rotating functionally graded cylindrical shells with orthogonal stiffeners is presented. Based on Love's first approximation theory and smeared stiffeners technique, the governing equations of motion which take into account the effects of initial hoop tension and also the centrifugal and Coriolis forces due to rotation are derived. The influence of the power law index, the stiffener's height-to-width ratio, the circumferential wave numbers, the shell length-to-radius ratio, and the shell radius-to-thickness ratio on the natural frequencies of the simply supported rotating stiffened functionally graded cylindrical shell are investigated. To validate the present analysis, comparisons are made with those available in the literature for particular cases; very good agreements are achieved.
