The twentieth century witnessed a great era with the launch of the flame of Science in both its human and applied aspects,which was kindled by researchers and scientists on their various interests, scientific research has always been the Pioneer towards a new hypothesis or theory as a summary of a phenomenon and a mixture of thought and therefore it is a window with Horizons towards a new universe and conclusion (Abdelbaki, 2004: 3).   .

This study investigates the feasibility of hand analysis for diagnosing neuroticism dimensions. Neuroticism, a personality trait characterized by emotional instability, anxiety, and susceptibility to stress, can have significant impacts on individuals' mental health and well-being. The study examines the relationship between certain hand features and neuroticism dimensions, aiming to develop a diagnostic tool for identifying neurotic tendencies based on hand analysis. Key hand features such as finger length ratios, palm size, and ridge patterns are analyzed in relation to neuroticism dimensions. Through empirical research and data analysis, the study assesses the accuracy and reliability of hand analysis as a diagnostic method for neuroticism dimensions. The findings offer insights into the potential use of hand analysis in psychological assessment and highlight its implications for understanding neuroticism traits.

This research investigates the formation of color associations through stable units formed with the participation of words expressing color. Language plays a significant role in shaping our perception of colors, and the formation of stable units—linguistic constructs involving color words—provides a framework for understanding how these associations are established and maintained. Through a combination of linguistic analysis and experimental methods, this study explores how stable units influence color perception, categorization, and conceptualization. By uncovering the cognitive mechanisms underlying the formation of color associations through stable linguistic units, this research contributes to our understanding of the intricate interplay between language and cognition.

Helical springs are fundamental components in various engineering applications, and optimizing their performance is crucial for enhancing overall system efficiency and reliability. This study investigates the impact of slender wire diameters on the performance of intelligent helical springs. Through experimental analysis and computational modeling, the mechanical behavior of helical springs with different wire diameters is examined, focusing on factors such as stiffness, fatigue life, and energy absorption capacity. The findings shed light on the trade-offs between wire diameter, spring compactness, and performance metrics, offering insights into the design and optimization of helical springs for diverse applications.

Infective endocarditis (IE) is an inflammatory process that occurs in the endocardium and also in implantable cardiac devices, the septum between the heart chambers, and in particular the heart valves, whether biological or prosthetic, this process comes from infection by some microorganism, especially bacteria. In 2023, the International Society of Cardiovascular Infectious Diseases (ISCVID) reformulated the diagnostic criteria, in particular those related to microbiological aspects. The aim of this study is to discuss the modified Duke criteria, therapeutic measures, and future challenges. The present study is a narrative bibliographical review that analyzed scientific production in online databases. Because it is a rare pathology, its annual incidence is between 3 and 10 cases per 100,000 people, and it is twice as common in males. Its treatment is complex, but its mainstay is antibiotic therapy and, when necessary, cardiac surgery. Empirical antibiotic treatment should be carried out as soon as possible after blood culture tests have been taken. In conclusion, IE is one of the most laborious and difficult medical conditions for physicians to practice, so it is important to employ a systemic approach based on scientific evidence for diagnostic investigation and therapeutic care for good results and patient well-being.
