Актуальность. Врождённые пороки сердца (ВПС) — самая распространённая группа врождённых аномалий развития и одна из ведущих причин неонатальной смертности [1–4]. Часть критических ВПС (CCHD) остаётся клинически нераспознанной к моменту выписки из родильного дома, что повышает риск декомпенсации и летального исхода. Цель — обобщить современные данные о подходах к диагностике ВПС у новорождённых и значении пульсоксиметрического скрининга. Методы. Проведён описательный (narrative) обзор публикаций PubMed/MEDLINE, Scopus, Web of Science, Google Scholar за 2009–2025 гг. с включением фундаментальных более ранних работ и доступных материалов Узбекистана. Результаты. Международный опыт (рекомендации AAP, AHA, CDC, европейский консенсус) подтверждает высокую специфичность пульсоксиметрии при умеренной дополнительной чувствительности к клиническому осмотру. Практическое значение. Стандартизированный протокол пульсоксиметрии в сочетании с осмотром и эхокардиографией обеспечивает своевременное направление к кардиологу. Заключение. Повсеместное внедрение неонатального пульсоксиметрического скрининга обоснованно снижает риск поздней диагностики критических ВПС.

1-tur qandli diabet bolalik va o‘smirlik davrida uchraydigan muhim surunkali endokrin kasalliklardan biri bo‘lib, insulin ishlab chiqaruvchi β-hujayralarning progressiv zararlanishi natijasida rivojlanadi. Kasallikning klinik belgilari qisqa vaqt ichida kuchayishi va ayrim bemorlarda diabetik ketoatsidoz bilan birinchi marta namoyon bo‘lishi mumkin. Shu sababli bolalarda kasallikni erta aniqlash, laborator tashxisni to‘g‘ri tashkil etish, glyukemik nazoratni ta’minlash va bemor hamda uning oilasini o‘qitish pediatrik endokrinologiyaning muhim vazifalaridan hisoblanadi. Ushbu maqolada bolalarda 1-tur qandli diabetning etiologik va klinik xususiyatlari, zamonaviy diagnostik mezonlari, insulinoterapiya, glyukozani monitoring qilish, ovqatlanish va jismoniy faollik, diabetik ketoatsidozning oldini olish hamda uzoq muddatli asoratlar skriningi tahlil qilindi. Zamonaviy xalqaro tavsiyalar bolalar va o‘smirlarda diabetni boshqarishda individual yondashuv, diabet bo‘yicha o‘z-o‘zini boshqarish ta’limi, glyukozani muntazam monitoring qilish va texnologiyalardan oqilona foydalanishga katta ahamiyat beradi. ISPADning 2024-yilgi konsensus tavsiyalarida bolalar va o‘smirlardagi diabetni boshqarish bo‘yicha yangi va yangilangan klinik tavsiyalar taqdim etilgan. ISPAD+1

Background: The first 1,000 days of life extend from conception to a child's second birthday and represent a critical period for maternal and child health. Longitudinal family accompaniment may support maternal risk identification, neonatal follow-up, feeding practices, and growth and developmental monitoring. Case: A 27-year-old woman with obesity and a high-risk obstetric history received longitudinal accompaniment during the first 1,000 days of life. In the third trimester, breech presentation was identified and the pregnancy risk-screening score was 20, indicating very high risk. A term female infant was delivered by caesarean section because of maternal hypertension and fetal malposition. Birth weight was 2,750 g, length was 47.7 cm, and the recorded Apgar score was 8. Clinical neonatal jaundice resolved on follow-up. Complementary feeding before six months was identified as the priority problem and addressed through family education. At 18 months, the child's weight was 10.6 kg, length 80.5 cm, and head circumference 46.5 cm; nutritional status was recorded as good and developmental prescreening was age-appropriate. Conclusion: This case illustrates continuity of family-centred accompaniment from very high-risk pregnancy to 18 months. Causal effects cannot be inferred from a single case without a comparator.

Jamoada orttirilgan pnevmoniya bolalik davrida uchraydigan muhim o‘tkir respirator kasalliklardan biri bo‘lib, ayniqsa kichik yoshdagi bolalarda og‘ir kechish va asoratlar rivojlanishi xavfi bilan tavsiflanadi. Kasallikning klinik belgilari bolaning yoshi, etiologik omili, immun holati va hamroh kasalliklariga qarab farq qilishi mumkin. Ushbu maqolada bolalarda jamoada orttirilgan pnevmoniyani zamonaviy tashxislash, og‘irlik darajasini baholash, differensial diagnostika, antibakterial davolash tamoyillari, kislorod terapiyasi, kuzatuv va profilaktika masalalari tahlil qilindi. Zamonaviy xalqaro tavsiyalarda pnevmoniya tashxisida klinik belgilarni kompleks baholash, nafas olish buzilishlari va gipoksemiyani o‘z vaqtida aniqlash, zarur hollarda pulsoksimetriyadan foydalanish hamda antibiotiklarni oqilona qo‘llash muhimligi ta’kidlanadi. JSSTning bolalarda pnevmoniya va diareyani boshqarish bo‘yicha yangilangan qo‘llanmasi 10 yoshgacha bo‘lgan bolalarni qamrab olib, pnevmoniyani birlamchi tibbiy yordam darajasida boshqarish imkoniyatlarini kengaytirgan.

Solver, driver scripts and every numerical output of a study of the efficiency and the retrieved-mode noise of a Lambda-type atomic quantum memory. The model is the one-dimensional Maxwell-Bloch system of a three-level ensemble with the anti-Stokes four-wave-mixing channel, integrated in JAX/Diffrax so that the derivative of an observable with respect to the control field comes from a reverse pass through the propagation. The noise observable is one row of the Bogoliubov kernel projected on the retrieved temporal mode, obtained without assembling the kernel. The outputs cover: the efficiency-noise front traced over a 32-knot control at two signal detunings; the largest singular value of the storage-retrieval map along that front and its dependence on the four-wave-mixing coupling; the spin-wave growth of the resonant anti-Stokes configuration over 2.5 decades of optical depth and a factor 15 in control amplitude; the efficiency, noise photon number and collinear phase mismatch of a cesium configuration taken from published experimental parameters; the derivative of each front point with respect to the optical depth, the spin decoherence, the phase mismatch and the four-wave-mixing coupling, each from one reverse pass; three optimizers compared at one evaluation budget and at three control dimensions, with the cost of a gradient measured against the cost of an objective on the same working point; the number of temporal modes the storage map resolves, on a ladder in the basis size at two spatial grids; the Doppler-averaged absorption of a warm vapour in closed form; three velocity quadratures measured against that closed form and against its derivative, which is the average the field's source carries; the integrator step a velocity-resolved solve needs, which is not the step the front was traced at; the landed controls of the second detuning read again under a 300 K Maxwellian, at one velocity class and at thirty; the Bogoliubov identity projected on the retrieved mode, evaluated at every front point; the noise the detector gate collects over every temporal mode, by stochastic trace estimation, and the effective mode count it gives against the retrieved-mode count; the same trace against the gate's own length; a manifest of every landed run with its detuning, step specification, bound and outcome; the reproducibility of the front, measured as the disagreement between two runs of one control that reach the same efficiency, and what that reproducibility does to a slope read off the front; the front re-traced at a constant integrator step over both searches, with the local logarithmic slope read on it at three efficiencies fixed before the set was read; the controls of the adaptive-step searches measured again at that step with each control held, and the joint front of both searches with its noise criteria and its slopes;the rows of every port of the output field, including the anti-Stokes Langevin port, on every control of both searches; and the 30 constant-step controls and three adaptive-step controls of the front measured again in the full equations, with both polarizations integrated in time. Every output file is plain text carrying its own configuration in a header and a machine-readable RESULT line; DEPOSIT.md maps the directories and names the script that produces each. The archive is a git archive of one commit, so the tree is exactly what that revision held.

Purpose: The objectives of the study were to examine the effect of electronic marketing on the development of the tourism and hospitality industry in Oman; To assess the influence of different dimensions of electronic marketing on the performance of tourism and hospitality businesses in Oman; and to determine the most influential electronic marketing dimension contributing to the development of the tourism and hospitality industry in Oman. Design/methodology/approach: This study adopted a mixed-methods approach using a descriptive research design to examine the effect of electronic marketing on the tourism and hospitality industry in Oman. Primary data were collected through a structured online questionnaire. The target respondents comprised local and international tourists who had experience using electronic marketing platforms during their travel. A convenience sampling technique was employed. Findings: The study found that electronic marketing has a significant positive influence on the tourism and hospitality industry in Oman. Respondents perceived e-marketing as essential for the future development of tourism, enhancing business promotion, creating positive first impressions, and improving global competitiveness. Social media emerged as the most effective electronic marketing channel. Regression analysis further confirmed a significant positive relationship between support for e-marketing and its perceived impact on tourism development. Research Implications: The findings contribute to the growing body of knowledge on digital marketing in tourism by providing empirical evidence from the Omani context. The study demonstrates the strategic importance of electronic marketing in enhancing tourism promotion and business competitiveness. It also offers a foundation for future research on digital marketing adoption, consumer behaviour, and the effectiveness of emerging technologies in the tourism and hospitality industry. Social Implications: The study highlights the potential of electronic marketing to improve public awareness of Oman's tourism attractions and hospitality services, thereby encouraging greater domestic and international tourism. Increased adoption of digital marketing can support employment generation, strengthen local tourism businesses, and contribute to economic diversification. Effective electronic marketing also enhances customer access to tourism information, resulting in improved travel planning and visitor experiences. Originality / Value: This study provides empirical evidence on the influence of electronic marketing on the tourism and hospitality industry in Oman, a context that has received relatively limited research attention. Unlike previous studies focusing on individual digital marketing tools, this research examines the overall contribution of electronic marketing to tourism promotion, hospitality development, and destination competitiveness, thereby offering practical insights for tourism businesses and policymakers in Oman.

A combined flowsheet for reprocessing old (stockpiled) cyanidation tailings is proposed. It includes washing and classification, regrinding of the coarse fraction, centrifugal gravity concentration, sulphide flotation, intensive cyanidation of concentrates and resin-in-pulp leaching of flotation tailings. Laboratory tests indicate that total gold recovery can be raised from 42-48 % (direct re-leaching) to 68-74 %.

This module is one of many that form the Ecological Monitoring System Australia (EMSA). EMSA has been developed by the Terrestrial Ecosystem Research Network (TERN) in collaboration with the Australian Government Department of Climate Change, Energy, the Environment and Water (DCCEEW). This module has been developed by the NESP Resilient Landscapes Hub, extending the EMSA collaboration to include TERN, DCCEEW and the NESP Hub. This module provides the procedures and guidelines for conducting an aerial survey of weeds across a project area. It involves systematically collecting data on the weed cover in a defined study area. The data can be used to map the distribution of weeds over time and to assist with reporting and analysis of the effectiveness of weed management. The procedures align with the national approach for weed survey outlined in A field manual for surveying and mapping nationally significant weeds (McNaught et al. 2008) Weed distribution data can be collected at any stage of a project. However, collecting it at the start helps managers prioritise weed management actions, and collecting it after management actions can be used to assess success and inform adaptive management.
