In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

results 22 patients were male (73.3%) and the mean age was 60.3 ± 10.6 years in our study group. the most common artery for cut off and run off was superior femoral artery in both assessments. proximal section of each artery was the most common anatomical section for cut off and run off. there was a same report of cut off artery by mr-angiography and surgery (kappa coefficient of agreement was ...

The connection of the tractor to the inactive trailer or motor vehicle causes a motion control problem when turning in the screw, forward or backward movements and high speeds. This is due to the inactive trailer being controlled by the tracking using a physical link that is not affected by the movement. Trailers usually take tracks under these conditions. This phenomenon is called Jack Knife. ...

For solving the linear algebraic equation Ax = b resulting from the numerical partial differential equations, the traditional conditions number is defined by Cond(A) = σ1 σn , where σ1 and σn are the maximal and minimal singular values of matrix A respectively. The condition number is used to provide the bounds of the relative errors from the perturbation of both A and b. Such a Cond can only b...

ウンシュウミカンの“貯蔵臭”による品質低下が問題とされている．貯蔵臭とは“長期貯蔵”されたカンキツ類から感じる食品異臭（オフフレーバー）とされているが，その詳細は明らかとなっていない．本研究では貯蔵臭をもつウンシュウミカンの選別法開発に向け，嗅覚官能評価によって貯蔵臭を定義すること，貯蔵臭物質を同定することを目的とした．常温および低温で長期貯蔵されたウンシュウミカン可食部を対象として嗅覚官能評価に供試した結果，常温区（25°C）と比較して低温区（4°C）において“草のようなにおい”が強まったことから，その印象を貯蔵臭として定義した．倉庫内部の臭気を評価したところ“草のような”においは感知できず，外部からの臭気付着は無いと考えられた．続いて“草のようなにおい”を対象として“におい嗅ぎガスクロマトグラフィー（GC-O）”をもちいて物質同定に取り組んだところ，p-シメネンが貯蔵臭物質として...

naesthetic drugs are often available in glass ampoules hich need to be ‘snapped open’ along the coloured bands r dot around the neck. Different manoeuvres can be mployed for opening these ampoules like snapping with humb and index finger (with or without using gauze pieces), cratching the neck of the vial with file or base of another ial and snapping open,1 using scissors2 or knife.
