Current techniques used to investigate the mechanisms responsible for the sensory responses to distension of the human esophagus provide limited information because the degree of circumferential stretch required to determine tension can only be inferred. We used impedance planimetry to measure the cross-sectional area during esophageal distension to ascertain the degree of stretch and tension t...
Helping Babies Breathe (HBB) is an evidence-based medical educational curriculum designed to improve neonatal resuscitation and be taught in resource-limited circumstances. It has been field-tested for educational effectiveness and feasibility of wide implementation. We are committed to supporting the expansion of effective neonatal care, agree that HBB is highly suitable for that purpose, and ...
this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...
یکی از مشکلات مهم سیستمهای قدرت که دارای مزارع بادی با ژنراتورهای القایی دوسوتغذیه هستند قابلیت ایستادگی در مقابل خطای این ژنراتورها و نوسانات توان خروجی آنهاست. در مواقعی که این ژنراتورها توان قابل توجهی از سیستم قدرت را تأمین میکنند خروج آنها در هنگام خطا، باعث ناپایداری شبکه میشود. طبق نیازهای جدید بر اساس کدهای شبکه، در مواقع خطا که ولتاژ در پایانه ژنراتور افت میکند، بایستی به منظور حفظ...
beta thalassemia is the most common autosomal recessive disorder. the present study reports a rare β globin gene mutation, hbb: c.180g>a: codon 59 (aag/aaa), in a patient from gilan province, northern iran. nucleotide sequencing of amplified dna belonging to a 35 years old man presenting mild hypochromia revealed a synonymous mutation due to a g>a conversion at the third position of codon 59 o...
ABSTRACT We study a sample of single Galactic post-asymptotic giant branch (post-AGB) stars with known surface chemical composition. Gaia EDR3 and DR3 parallaxes have enabled accurate determinations the luminosities these objects, thus making it possible to characterize them in terms their initial masses, compositions, progenitor ages. used extant evolutionary sequences asymptotic (AGB) produce...
We present the results of extensive computation of the Thermal Pulse phase AGB evolution of stars of metallicities in mass fraction 2 10 ?4 Z 0:01, for those masses in the range 2:5 M=M 6, which suuer the Hot Bottom Burning (HBB) phase. The evolution is fully computed, by assuming a mass loss rate consistent with the observations of the Magellanic Clouds lithium rich stars, and modelling convec...
Bệnh Thalassemia là bệnh di truyền phổ biến nhất trên thế giới. Ước tính tỷ lệ mang gen thalassemia trung bình trong cộng đồng tất cả các dân tộc Việt Nam 13,8%. β-thalassemia thể nặng có biểu hiện thiếu máu tan nặng, ảnh hưởng đến khả năng sống, chất lượng sống của người bệnh. Việc sàng lọc, chẩn đoán sớm bệnh, đóng vai trò quan trọng giúp hạn chế sinh ra trẻ mắc β-thalassemia. Nhiều kỹ thuật ...
