background: appropriate endurance exercise can change bone mass density and strength of weight-bearing bones in both animals and humans, but its effects on the microstructure are not known. this study aimed to determine skeletal changes induced by the treadmill running endurance in ovariectomized adult mice. methods: twenty-seven adult female rats were divided into experimental and control grou...
A hybrid artificial neural network with Dempster-Shafer theory for automated bearing fault diagnosis
جریان سیال در بیشتر مسائل مهندسی بصورت متلاطم صورت می گیرد. بنابراین مطالعه تلاطم و بررسی مشخصات جریانهای متلاطم از اهمیت خاصی برخوردار است . در گذشته نه چندان دور مطالعات در این زمینه تماما بصورت تجربی و آزمایشگاهی بوده است اما امروزه، استفاده از متدهای محاسباتی توسعه پیدا کرده است بطوری که می رود تا جایگزین قسمت اعظمی از مطالعات مدلی و روشهای تجربی شود. در این تحقیق مشخصات جریان متلاطم با تقا...
We have constructed a hybrid cDNA coding for a fusion protein between human interleukin 2 and a truncated heavy chain from human immunoglobulin M. The protein encoded by this cDNA contains the entire interleukin 2 sequence including its signal peptide, fused at its C terminus to domains 2 to 4 of the immunoglobulin heavy-chain constant region. Cells transfected with the hybrid cDNA secrete mult...
BACKGROUND This prospective experimental study evaluated the surgical procedure and results of modular hybrid total hip arthroplasty in dogs. METHODS Ten skeletally mature healthy mongrel dogs with weights varying between 19 and 27 kg were used. Cemented modular femoral stems and uncemented porous-coated acetabular cups were employed. Clinical and radiographic evaluations were performed befor...
To date the self-assembly of ordered metal nanoparticle (NP)/block copolymer hybrid materials has been limited to NPs with core diameters (D(core)) of less than 10 nm, which represents only a very small fraction of NPs with attractive size-dependent physical properties. Here this limitation has been circumvented using amphiphilic brush block copolymers as templates for the self-assembly of orde...
This study examines the feasibility of applying adaptive fuzzy sliding mode control (AFSMC) strategies to reduce the dynamic responses of buildings constructed using a lead rubber bearing (LRB) isolation hybrid protective system. Recently developed control devices for civil engineering structures, including hybrid systems and semi-active systems, have been found to have inherent nonlinear prope...
Here, we report the draft genome sequence of Micromonospora sp. DSW705 (=NBRC 110037), a producer of antitumor cyclic depsipeptides rakicidins A and B, together with the features of this strain and generation, annotation, and analysis of the genome sequence. The 6.8 Mb genome of Micromonospora sp. DSW705 encodes 6,219 putative ORFs, of which 4,846 are assigned with COG categories. The genome ha...
Bearings are one of the most critical components in many industrial machines. Predicting remaining useful life (RUL) of bearings has been an important task for condition-based maintenance of industrial machines. One critical challenge for performing such tasks in the era of the Internet of Things and Industrial 4.0, is to automatically process massive amounts of data and accurately predict the ...
This study examines the feasibility of applying adaptive fuzzy sliding mode control (AFSMC) strategies to reduce the dynamic responses of bridges constructed using a lead rubber bearing (LRB) isolation hybrid protective system. Recently developed control devices for civil engineering structures, including hybrid systems and semi-active systems, have been found to have inherent nonlinear propert...
