Precast post-tensioned segmental (PPS) bridge piers mitigate global and local damages of structures through natural hinges (joints between their segments) rocking motion segments. The application the PPS is currently growing in Accelerated Bridge Construction (ABC) where segments are manufactured offsite with higher quality, assembled onsite a short time. Structural vulnerability analysis very ...

Purpose In order to explore the damage probability of bridge engineering in event earthquake construction stages, analysis method seismic vulnerability stages is proposed this paper. Design/methodology/approach Based on joint simulation function stage conditions and response MIDAS/Civil finite element software, combined with IDA compared relationship between demand capacity. Findings The resear...

Serving as one key component of the most important lifeline infrastructure system, transmission towers are vulnerable to multiple nature hazards including strong wind and could pose severe threats to the power system security with possible blackouts under extreme weather conditions, such as hurricanes, derechoes, or winter storms. For the security and resiliency of the power system, it is impor...

INTRODUCTION Inadequate nutrition has a severe impact on health in India. According to the WHO, iron deficiency is the single most important nutritional risk factor in India, accounting for more than 3% of all disability-adjusted life years (DALYs) lost. We estimate the social costs of iron deficiency anemia (IDA) in 6-59-month-old children in India in terms of intangible costs and production l...

According to the theory of passivity-based control (PBC), this paper establishes a port-controlled Hamiltonian system with dissipation (PCHD) model for a doubly fed induction generator (DFIG) system under unbalanced grid voltage conditions and proposes a method of interconnection and damping assignment passivity-based control (IDA-PBC) of the system under such conditions. By using this method, ...

-The generalized predictive control algorithm, it’s parameter adaptive recursive predicting and noise estimator is presented for a class of non-linear discrete-time systems with multiple time delays based on dynamic approximate non-linearization increment minimized recursive predicting model method. Generalized predictive control is employed for nonlinear systems with heavy multiple time delays...

We evaluated the combination of two indices of red blood cell count (RBC) and red blood cell distribution with index (RDWI) and extrapolated HbA2 values in differential diagnosis of iron deficiency anemia (IDA) and beta-thalassemia traits (BTT) associated with IDA. A total 129 subjects were included in this study. RBC/RDWI was able to diagnose 32% beta-thalassemia with iron deficiency while 66%...

Endoscopic gastrointestinal workup fails to establish the cause of iron deficiency anemia (IDA) in a substantial proportion of patients. In patients referred for hematologic evaluation with unexplained or refractory IDA, screening for celiac disease, autoimmune gastritis, Helicobacter pylori, and hereditary forms of IDA is recommended. About 4% to 6% of patients with obscure refractory IDA have...

Event-related potentials (ERP) were assessed in 70 school-aged children with a diagnosis of asymptomatic iron deficiency anaemia (IDA), based on low haemoglobin and either low serum ferritin or high free erythrocyte protoporphyrin levels. The IDA subjects were randomized into treatment and placebo groups of 35 cases each, and compared with a normal control group of 30 age- and gender-matched he...

BACKGROUND The frequent need for blood transfusion in children with SCA creates the impression that IDA is rare in this class of children. OBJECTIVES The objective of the study is to determine the prevalence of IDA in a population of under-five children with SCA in Lagos, Nigeria. METHODOLOGY Serum iron, total iron binding capacity, transferrin saturation and serum ferritin were assayed in ...
