Reusing the data collected during an epidemiological study is a complex task. This is mainly due to the frequent utilization of traditional storage supports, as well as specific formats and/or terminologies which can make it difficult to integrate the gathered data with data from other information resources. Using terms from the UMLS Metathesaurus, we have annotated the data collected during th...

Digital aerial photogrammetry has recently attracted great attention in forest inventory studies, particularly in countries where airborne laser scanning (ALS) technology is not available. Further research, however, is required to prove its practical applicability in deriving three-dimensional (3D) point clouds and canopy surface and height models (CSMs and CHMs, respectively) over different fo...

هدف اصلی تست پره توربین بادی، نشان دادن سطح قابل قبولی از اطمینان در مورد این موضوع است که وقتی پره ای بر اساس مشخصات معین تولید میشود، استحکام و طول عمر در نظر گرفته شده در طراحی پره را دارا میباشد. باید نشان داده شود که پره می تواند در برابر هم بارهای نهایی (تست استاتیکی) و هم بارهای خستگی (تست دینامیکی) که در طی طول عمر طراحی خود، انتظار می رود با آن مواجه شود، مقاومت کند. یکی از الزامات اج...

When a person standing upright raises an arm on cue, muscles of the left and right sides of the body exhibit changes prior to and specific to the responding arm. We had standing participants perform a visual lexical decision task ("is this letter string a word?"), responding yes by raising one arm and no by raising the other arm. We recorded onset of the arm movement and onset of electromyograp...

Chinese fir (Cunninghamia lanceolata [Lamb.] Hook) is one of the most important plantation tree species in China with good timber quality and fast growth. It covers an area of 8.54 million hectare, which corresponds to 21% of the total plantation area and 32% of total plantation volume in China. With the increasing market demand, an accurate estimation and prediction of merchantable volume at t...

The purpose of the present study was to investigate the effect of dual task training including balance sit-to-stand and cognitive exercises on postural control of sit to stand of elderly women with a history of falling. 15 elderly women were randomly divided into control (n=7) and experimental (n=8) groups. Participants implemented training protocol for four weeks in both experimental (balance ...
