Value of blood pressure measurement earlier versus later in life to predict cardiovascular mortality
Abstract Hypertension is a potent risk factor for cardiovascular morbidity and mortality. High blood pressure (BP) correlates closely with all-cause The purpose of this study was to compare the value systolic earlier versus later in life predict In observation (OS) we prospectively recorded fatal events over up 19 years 1282 patients whom 570 had Metabolic Syndrome (MetS) at baseline. These par...
Cross-country skiing causes strain in the airways because skiers train and compete cold air. The aim of this survey was to investigate prevalence age at onset asthma, asthma control, use medication Finnish competitive cross-country skiers. All who were enrolled largest national competitions winter 2019 (n = 1282) invited study via Ski Association. A control group 1733) matched for responding by...
Abstract We use Paschen- β (Pa ; 1282 nm) observations from the Hubble Space Telescope G141 grism to study star formation and dust-attenuation properties of a sample 29 low-redshift ( z < 0.287) galaxies in CANDELS Ly α Emission at Reionization survey. first compare nebular attenuation Pa /H with stellar inferred spectral energy distribution, finding that our are consistent an average ratio ...
Fossil fuels are non-renewable, finite, and exhausting. Therefore, it is necessary to find alternative sources of energy. Solar energy abundant in nature, so can be considered as the best meet demand. It sustainable, renewable, scalable. Increasing efficiency harnessing solar should one our top concerns because a renewable resource. The challenge utilizing this increase well reduce production c...
The concept of total quality management improves an organization’s performance, but there are several obstacles to its practical application. This study therefore identifies the implementing Total Quality Management (TQM) framework in Ghanaian construction sector. A survey questionnaire was employed for study, and results were based on responses from 536 641 questionnaires sent out top sample f...
The mafic and ultramafic igneous rocks of the ophiolitic complex in eastern Birjand) between Sulabest in southern part to north of Gazik in northern part) Have been studied. According to plot of data on diagrams and the result of mineralogy and geochemistry, gabbros and some peridotites belong to cummulate series of spreading sea floor magma (MORB) where some peridotites are of metamorphic (tec...
این تحقیق به منظور ارزیابی نظام مدیریت منابع انسانی شرکت بهره برداری نفت و گاز آغاجاری در سطح دوم مدل بلوغ قابلیت افراد و یا سطح مدیریت شده، انجام گرفت. روش تحقیق توصیفی-پیمایشی و جامعه آماری آن شامل 1282 نفر از کارکنان شاغل در بخش های عملیاتی شرکت آغاجاری و همچنین 128 تن از مدیران و سرپرستان می باشد که با روش نمونهبرداری تصادفی طبقهای بر اساس روش های آماری یک نمونه 100 نفری از کارکنان و یک نمو...
The hypothesis that increased ADAMTS13 (a disintegrin and metalloprotease with thrombospondin repeats) activity or increased susceptibility of von Willebrand factor (VWF) to proteolysis by ADAMTS13 may underlie type I von Willebrand disease (VWD) in some patients was investigated. Plasma from 4 patients with type I VWD was cryoprecipitated. ADAMTS13 activity in the VWF-poor cryodepleted fractio...
Identification of hematopoietic progenitor cells in the zebrafish (Danio rerio) has been hindered by a lack of functional assays to gauge proliferative potential and differentiation capacity. To investigate the nature of myeloerythroid progenitor cells, we developed clonal methylcellulose assays by using recombinant zebrafish erythropoietin and granulocyte colony-stimulating factor. From adult ...
Growing MnO2 nanocrystals in the bulk of porous carbon nanofibers is conducted in a KMnO4 aqueous solution aimed to enhance the electrochemical performance of MnO2. The rate of redox reaction between KMnO4 and carbon was controlled by the concentration of KMnO4 in a neutral solution. The MnO2 nanoparticles grow along with (211) crystal faces when the redox reaction happens on the surface of fib...
