Maqolada turizm sohasining jahon iqtisodiyotidagi o‘rni, eksport va bandlikka ta’siri statistik ma’lumotlar asosida tahlil qilingan. Turizmni rivojlantirishda statistik baholashning ahamiyati, O‘zbekistonda esa bu yo‘nalishda xalqaro standartlarga mos yondashuvlarni joriy etish zarurati asoslab berilgan. Shuningdek, turizm statistikasini takomillashtirish va innovatsion tahlil usullarini qo‘llash bo‘yicha takliflar ilgari surilgan. Mazkur yo‘nalishda ilmiy-amaliy tadqiqotlarni chuqurlashtirish bugungi kunning dolzarb vazifasidir.

Background. Endothelial activation is a key mechanism in the development of postoperative pulmonary thromboembolism (PTE). The expression of the lysosomal membrane glycoprotein CD63 reflects platelet activation, endothelial injury, and exocytosis of Weibel–Palade bodies containing von Willebrand factor (vWF) and P-selectin. However, age-related changes in CD63 expression during postoperative PTE remain insufficiently investigated.

This study investigated reckless driving, transport-related crime, and passengers' safety perception in commercial tricycle operations in Obio/Akpor Local Government Area of Rivers State, Nigeria. The growing dependence on tricycles as a dominant mode of intra-urban transportation in semi-urban communities has raised concerns regarding road safety and passenger security. A descriptive survey research design within a mixed-methods framework was adopted. Data were collected using structured questionnaires and semi-structured interviews. A total of 400 questionnaires were distributed, and 362 valid responses were retrieved and analysed. Quantitative data were analysed using descriptive statistics, chi-square test, and Pearson Product-Moment Correlation, while qualitative data were thematically analysed. Findings revealed a high prevalence of reckless driving behaviours among tricycle operators, including overspeeding, disobedience of traffic regulations, wrong parking, sudden stops, and dangerous overtaking (Grand Mean = 3.11). Transport-related crime was also evident, with respondents reporting incidents of theft, harassment, "one-chance" operations, and insecurity along certain routes (Grand Mean = 2.96). Passengers' safety perception was generally low (Grand Mean = 2.89), despite continued reliance on tricycles due to limited transportation alternatives. Inferential statistics showed significant relationships between reckless driving and safety perception (χ² = 24.56, p = 0.003) as well as between transport-related crime and safety perception (χ² = 21.34, p = 0.011). Correlation analysis further indicated strong negative relationships between reckless driving and safety perception (r = -0.71, p < 0.001) and between transport crime and safety perception (r = -0.68, p < 0.001). Qualitative findings supported these results, revealing that economic pressure, weak enforcement of traffic regulations, and route insecurity significantly contribute to unsafe driving behaviours and transport-related insecurity. The study concludes that reckless driving and transport-related crime are major determinants of passengers' safety perception in commercial tricycle operations. It recommends strengthened traffic enforcement, improved security surveillance, enhanced regulation of informal transport systems, and continuous driver training to improve safety outcomes and restore public confidence.

У монографії узагальнено літературну інформацію та результати власнихдосліджень авторів, що стосуються різних аспектів реакції рослин на дію алюмінію.Розглянуто особливості поступання у рослини цього елемента та його розташування ворганах, тканинах і клітинах, накопичення та акумуляцію. Представлено результатидосліджень про вплив алюмінію на основні фізіологічні процеси. Значну увагуприділено клітинно-генетичним механізмам стійкості рослин проти цьогонебезпечного токсичного елемента.Монографія розрахована на науковців, аспірантів, студентів та фахівців зекології, фізіології рослин, рослинництва, грунтознавства, патофізіології іфітоімунітету.
