Abstract This paper studies the aerodynamic performance and noise characteristics of a 6 MW horizontal axis wind turbine based on CFD fluid simulation acoustic analogy method. The influence different flow velocities wake are compared. result shows that: main load source is shaft flow; airflow through engine room tower, blade, tower will make speed change, form large range low-speed area in rear wheel; maximum axial velocity loss wakes at sections under speeds located hub; behind high...

The early light-induced proteins (ELIPs) are postulated to act as transient pigment-binding that protect the chloroplast from photodamage caused by excessive light energy. Desert mosses such Syntrichia caninervis, desiccation-tolerant and homoiochlorophyllous, often exposed high-light conditions when both hydrated dry ELIP transcripts accumulated in response dehydration. To gain further insights into gene function moss S. two cDNAs cloned ScELIP1 ScELIP2 sequences were used basis of a...

LncRNA CASC11 is an oncogene in several types of cancer, while its role atherosclerosis unknown. In the present study we found that was downregulated, IL-9 upregulated plasma patients compared with healthy controls. Altered levels and distinguished from were significantly inversely correlated but not Exogenous treatment failed to affect expression vascular smooth muscle cells (VSMC), overexpression resulted downregulation IL-9. also proliferation promoted apoptosis VSMC. Therefore, may...

Salt bladders are specialized epidermal structures that halophytes use to store and excrete excess salt. However, the cell wall composition during salt bladder development is unclear, functions of in a few wild plants remain unexplored. Therefore, present study examined development, composition, their roles under stress by employing bladder-brushed unbrushed Chenopodium album plants. We found C. was connected cells through rectangular stalk developed from shoot tip young leaves. The...

In this paper, we present two deterministic weighted scale-free networks controlled by a weight parameter [Formula: see text]. One is fractal network, the other one non-fractal while they have same distribution when text] identical. Based on their special network structure, study random walks with trap located at fixed node. For each calculate exact solutions for average trapping time (ATT). Analyzing and comparing obtained solutions, find that ATT all grow asymptotically as power-law...

Abstract Background Aortoesophageal fistula (AEF) caused by an esophageal foreign body is a life-threatening crisis, with rapid progress and high mortality. The first case of AEF was reported in 1818, but the successfully managed not until 1980. Although there have been some reports on this condition, most cases, aorta invaded corroded due to its adjacent relationship esophagus subsequent mediastinitis. To date, few described aortic wall directly penetrated sharp body, likely because type...

Ferula spp. is an essential crop in Central Asia with pronounced economic benefits governed by its flowering process. However, the mechanisms of phenotype remain unclear.

Esophageal small cell carcinoma (ESCC) is an aggressive disease with poor prognosis. This study sought to describe immunohistochemical (IHC) and clinicopathological features of patients ESCC, clarify how the utilization different marker combination affects prognostic outcome.The paraffin-embedded ESCC samples 73 were immunohistochemically analyzed neuron specific enolase (NSE), chromogranin A (CgA), synaptophysin (Syn) thyroid transcriptional factor-1 (TTF-1). The positivity these factors...

We conducted laboratory experiments to determine the lethal temperatures of shoots dried Bryum argenteum and how this restoration species responds extreme environments. specifically assessed changes in gene expression levels B. plants that were subjected sudden heat shock (control (20 ± 2°C), 80°C, 100°C, 110°C or 120°C) followed by exposure for an additional 10, 20, 30 60 min. After they exposed heat, samples placed wet sand medium, their survival regeneration abilities evaluated daily 56...

Effective strategies for managing patients with pulmonary focal Ground-glass Opacity (fGGO) depend on the pretest probability of malignancy. Estimating a clinical malignancy in fGGOs can facilitate selection and interpretation subsequent diagnostic tests. METHODS : Data from fGGO lesions, who were diagnosed at Sun Yat-sen University Cancer Center, was retrospectively collected. Multiple logistic regression analysis used to identify independent predictors develop predictive model estimate...

Hand-Assisted Thoracoscopic Surgery for pulmonary metastasectomy through sternocostal triangle access allows manual palpation of both lungs, thus permitting effective treatment lung metastases. In our research, 62 patients from November 2001 to January 2012 underwent procedures metastasectomy. Clinical data, including the number metastases determined by Computed Tomography/Positron Emission Tomography-Computed Tomography, surgical findings and survival data these were collected. We found...

Objective The study was designed to investigate the serum levels of HE4 in patients with lung cancer,and explore its prognostic value.Methods Blood samples 106 healthy adults and 191 cancer before treatment were measured by means ELISA for different stages pathological types,for analyzing effect HE4.Results (median level 91.63 pmol/L) significantly higher than control group 56.42 (U =3 081.00,P ＜ 0.05).AUC 0.85,with a cut-off value 82.70 pmol/L (specificity =95.31％,sensitivity =62.32％).HE4...

Introduction. Abscisic acid (ABA) is a plant hormone known to regulate environmental stress responses in various species. Endogenous ABA has been detected only limited number of bryophyte species.Methods. Samples the desiccation-tolerant moss Syntrichia caninervis Mitt. were analysed by ultra-performance liquid chromatography–mass spectrometry determine endogenous content gametophores. Quantitative real-time PCR was conducted investigate transcript abundance ABA-related genes (ZEP, NCED3,...

ABI3 (ABSCISIC ACID INSENSITIVE 3) is a family of B3 transcription factors essential for regulating the abscisic acid (ABA) signaling pathway involved in various biological processes and abiotic stress. Our previous studies demonstrated that ectopic expression ScABI3 from desiccation-tolerant moss (Syntrichia caninervis) into Arabidopsis thaliana enhanced stress tolerance. However, on plant transformation using gene are limited other possible functions not known. Here, we transformed alfalfa...

Narrow bandwidth, MeV-level photon beams can be generated by Thomson scattering of laser light from fast electrons. Intense sources (> 1 MeV, 108 photons/shot) plasma accelerated GeV electrons present the possibility for compact active interrogation devices. However, characterization such intense is inherently challenging due to mm-scale focusing and fs-scale pulse duration. A solution both spatial energy distributions each shot employ a low mass material track scattered Compton electron's...
