The automatization of the heart is its fundamental ability to independently generate electrical impulses that initiate heart contractions, without external stimulation from the nervous system. This review is devoted to a comprehensive review of this phenomenon. The main driver of the rhythm is normally the sinoatrial (CA) node, whose cells have unique electrophysiological properties, in particular, the ability to slow spontaneous diastolic depolarization (phase 4 of the action potential). This process is based on the complex dynamics of ion currents, including the "funny" current (If), calcium currents (ICa,T, ICa,L) and potassium currents (IK). The review examines in detail the ionic mechanisms of pacemaker activity, the hierarchy of pacemakers (CA node, atrioventricular node, Gis-Purkinje system) and the phenomenon of suppression of the underlying centers of automatism (overdrive suppression). The mechanisms of regulation of heart rate by the autonomic nervous system (sympathetic and parasympathetic), humoral factors (adrenaline, thyroid hormones) and other influences (temperature, ion balance, hypoxia) are highlighted. The clinical significance of automation is discussed, including pathological conditions such as CA node dysfunction (sinus node weakness syndrome), ectopic foci of automatism, atrial and ventricular arrhythmias associated with abnormal automation, as well as approaches to their diagnosis (ECG) and treatment (antiarrhythmic drugs, artificial pacemakers). In conclusion, modern research directions in this field are considered, including the study of the genetic basis of automatism disorders and the development of biological rhythm drivers.

1993-yilda Movarounnahr musulmonlari idorasi tizimida muhim oʻzgarish-muftiy, shayx Muhammad Sodiq Muhammad Yusufning isteʻfoga chiqishi va uning oʻrniga yangi muftiy tayinlanishi yuz berdi. Ushbu voqea idora tarixidagi muhim bosqich boʻlib boʻlib, 1996-yilgacha boʻlgan davr, hozirgi Oʻzbekiston musulmonlari idorasi tizimining shakllanishida soʻngi bosqich hisoblanadi. Mazkur maqolada bu davrda yuz bergan muhim voqeliklar, tarixiy hodisalar va ularning tahlili haqida soʻz boradi.

Public speaking anxiety, or glossophobia, is one of the most common fears experienced by individuals across all age groups and professions. Despite the universal nature of this fear, the ability to speak confidently in public remains essential for academic, professional, and personal development. This article explores the psychological roots of public speaking anxiety and offers a range of practical techniques to manage and overcome it. Through mental preparation, controlled breathing, progressive exposure, and cognitive restructuring, individuals can reduce fear and build lasting confidence. The article provides a structured approach to conquering anxiety and transforming public speaking into a skill that empowers rather than terrifies.

Mazkur maqolada shaharlarda yuzaga kelayotgan mikroiqlim o‘zgarishlari va ular bilan bog‘liq ekologik muammolar muhokama qilinadi. Asosiy e’tibor muhandislik asosidagi yechimlarga — yashil tomlar, aqlli ventilyatsiya tizimlari, aerodinamik loyihalash, suvni qayta aylantirish tizimlari kabi yondashuvlarga qaratilgan. Shahar iqlimini nazorat qilish orqali ekologik barqarorlikka erishish yo‘llari tahlil qilinadi.
