This article explores Iran-Ottoman relations during the Qajar era (1794–1925), highlighting both cooperation and competition between the two neighbors. Their collaboration brought significant achievements in economy, culture, politics, and security, while conflicts—mainly rooted in border issues, ethnic minorities, and foreign interventions (particularly Russian and British)—often led to wars. Despite these tensions, efforts to maintain peaceful relations marked this era as relatively stable compared to earlier periods like the Safavid, Afsharid, and Zand dynasties. Key events such as the First and Second Treaties of Erzurum reflect the deepening of bilateral ties. Although full success was not achieved, this period holds a notable place in the history of both nations for fostering cooperation in political, cultural, economic, and military spheres. The study adopts a descriptive and library-based research approach, concluding that these shared interests are strong foundations for continued collaboration.

Wilms tumor (nephroblastoma) is the most prevalent primary malignant renal tumor in children, accounting for approximately 90% of pediatric renal malignancies. Early and accurate diagnosis plays a critical role in the prognosis and overall treatment success. The role of radiological imaging in Wilms tumor extends beyond mere detection; it includes staging, treatment planning, and monitoring response to therapy. This article provides an in-depth analysis of the diagnostic effectiveness of ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) in detecting Wilms tumor in children. Comparative evaluations of each modality’s sensitivity, specificity, and limitations are supported by recent case statistics and clinical findings. An integrated radiological approach can enhance clinical outcomes, reduce unnecessary surgical interventions, and facilitate personalized care strategies.

The relationship between a speaker’s native language (L1) and their pronunciation in a second language (L2) has long been recognized as a critical area of study within second language acquisition. Pronunciation is not merely about producing sounds correctly; it encompasses various phonological elements such as stress, rhythm, intonation, and syllable structure — all of which are deeply shaped by the learner's first language. This paper aims to explore the extent to which L1 interferes with or supports the acquisition of accurate L2 pronunciation. It investigates both segmental (individual sounds) and suprasegmental (prosodic features) aspects of speech, presenting evidence from various language groups to illustrate common patterns of transfer. Moreover, the study discusses how phonological habits from the native language often lead to a foreign accent and reduced intelligibility in the second language, even among otherwise proficient speakers. Emphasis is placed on practical strategies and pedagogical approaches that can be used to address L1-induced difficulties, such as contrastive analysis, phonetic training, and the use of technological tools for self-monitoring and feedback. The paper concludes that although native language influence is a natural and often unavoidable aspect of second language learning, its impact on pronunciation can be significantly minimized through targeted instruction and increased learner awareness.
