investigated for the first time. At temperatures in the range 2 K&T&12 K a crossover of these corrections from one-dimensional behavior to zero-dimensional behavior is observed. It is shown
that the phase coherence length in the wires studied is less than the length...

The variation of the magnetoconductance with the magnetic flux J threading one unit cell in the chains for different Fermi energies of the electrons...

The seed of a scientific breakthrough may slumber for a decade or even longer without generating much interest. The seed may be a theoretical concept without clear predictions to test experimentally, or an intriguing but confusing experiment without...

In applying a positive gate bias, we create a metallic puddle under the gate surrounded by an insulating region. Charging of the puddle occurs via electron tunneling from a metallic edge channel. Analysis of the data allows direct extraction of this... [Show full abstract]Data provided are for informational purposes only. Although carefully collected, accuracy cannot be guaranteed.

Please enable JavaScript to use all the features on this page., June 1991, Pages Author links open overlay panelShow moreAbstractTotal hydrolyzed amino acids (THAA), total organic carbon (TOC), and total nitrogen (TN) have been measured in an oxic and anoxic surface sediment from the inner Oslofjord. Downcore variations of these parameters are ascribed to both diagenesis and changes in organic matter supply, the latter being most important. These changes are most prominent in the anoxic sediment, which reflects the eutrophication history of the innermost part of the fjord. Downcore, THAA content decreased from 3.8 to 2.0 mg/g (salt-free dry weight) in the oxic sediment and from 22.3 to 3.8 mg/g in the anoxic sediment. Total amino acid nitrogen varied between 17 and 34% of total nitrogen in the oxic, and 25 and 54% in the anoxic, sediment.Organic carbon and organic nitrogen accumulation rates and depth integrated mineralization rates are about three times higher in the anoxic sediment than in the oxic sediment. Recycling of amino acids accounted for 4 to 12% of the total organic carbon and 13 to 40% of the total organic nitrogen regenerated in these sediments.Check if you have access through your login credentials or your institution.ororRecommended articlesCiting articles (0)英菲克 || 让更多的人享受到科技进步的快乐|智能硬件|智能家居|网络机顶盒|智能穿戴

英菲克鼠标热评
鼠标超薄靓眼，非常漂亮，按键也没有声音，采用手机usb接口充电，即便充电期间也可以当作有线鼠标使用。扁长的外形适合女生，很不错值得拥有。
黑木纹版鼠标相比PM2其他型号更具特色，比起原木纹，褐色木纹提供了更别样另类的选择。鼠标造型低趴，DPI也方便调节，尤其适合笔记本用户选择购买，比较养眼吧。
亲肤手感不出油，七彩呼吸灯的有线电竞款看着就爽！不但造型适合我这种大手，而且两侧还有护翼，手感颇佳！超高的DPI对于我这种游戏玩家再合适不过，买它准没错
