Software Defect Classes and No-fault Liability
Software is increasingly used to control systems that can cause harm to the consumer. There is consensus among commentators that many software systems are “products” for purposes of the law of products liability. However, strict products liability in tort has yet to be applied to software products. The day is certainly coming. The Restatement of the Law, Third, Products Liability, explains that...
متن کاملNeural Tube Defect and Folic Acid
نقص لوله عصبی یکی از ناهنجاریهای مادرزادی مهم و شایع می باشد که شیوع آن بیش از ۵/ ۴ در ۱۰۰۰ تولد زنده است. اتیولوژی و پاتوژنز بیماری هنوز ناشناخته است. مطالعات اخیر بر روی حیوانات نشان می دهد که این ناهنجاری ممکن است، ناشی از متابولیسم غیر طبیعی هموسیستئین باشد. در مطالعات اخیر مشخص شده است که پیشگیری از نقص لوله عصبی (NTD) بوسیله اسیدفولیک مؤثر می باشد.
متن کاملNo increased bone formation around alendronate or omeprazole loaded bioactive bone cements in a femoral defect.
Alendronate and omeprazole have been found to influence bone healing by interfering with osteoclastic activity, resulting in increased bone formation. The biological effect of these conventional drugs, incorporated into bioactive bone cement (G2B1), was investigated in a rabbit model. The 2 materials and a control were inserted in defects created in the femoral condyle of rabbits. Implantation ...
متن کاملOn Graphs with Cyclic Defect or Excess
The Moore bound constitutes both an upper bound on the order of a graph of maximum degree d and diameter D = k and a lower bound on the order of a graph of minimum degree d and odd girth g = 2k + 1. Graphs missing or exceeding the Moore bound by ǫ are called graphs with defect or excess ǫ, respectively. While Moore graphs (graphs with ǫ = 0) and graphs with defect or excess 1 have been characte...
متن کاملOn graphs with excess or defect 2
The Moore bound m(d, k) = 1 + d ∑k−1 i=0 (d − 1)i is a lower bound for the number of vertices of a graph by given girth g = 2k + 1 and minimal degree d. Hoffmann and Singleton [5], Bannai and Ito [1], Damerell [4] showed that graphs with d > 2 tight to this bound can only exist for girth 5 and degree 3, 7, 57. The difference to the Moore bound by given girth is called the excess of a graph. In ...
