III-V on silicon DFB laser arrays

We will present our work on epitaxially grown III-V on silicon DFB laser arrays, including results of pure InP-based lasers emitting around 900nm and InGaAs-on-InP lasers emitting around 1300nm

Modulation of renal autoregulation by nitric oxide - cellular mechanism

Normal renal function requires stable renal blood flow. It is achieved by autoregulation. Nitric oxide contributes to the regulation of multiple pathways that are relevant to myogenic autoregulation. We examined the signal transduction mechanism of nitric oxide on myogenic autoregulation in the present thesis. Because some paracrine factors contribute to the renal autoregulation, we first isolate the effects of nitric oxide from other paracrine factors. The pressor and renal vasoconstrictor responses to nitric oxide synthase inhibition are independent of angiotensin II. There is an interaction between nitric oxide and endothelin, mediated by endothelin B receptors, that affects renal blood flow and renal autoregulation. Y-27632, Rho-kinase inhibitor reverses completely the enhanced myogenic autoregulation by L-NAME, and L-NAME does not affect the myogenic autoregulation pre-treated by Y27632. In conclusion, the effect of Rho-kinase with consequent inhibition of myosin light chain phosphatase may be an essential component of the modulation of myogenic autoregulation by nitric oxide. Therefore, the signal transudation of nitric oxide on renal autoregulation passes through Rho-kinase pathway

Reaction method control of impurity scattering in C-doped MgB2: proving the role of defects besides C substitution level

In this study, Si and C were incorporated into polycrystalline MgB 2 via in situ reaction of Mg and B with either SiC or with separate Si and C (Si+C). The electrical transport and magnetic properties of the two series of samples were compared. The corrected resistivity at 40 K, ρA(40 K), is higher for the samples reacted with SiC regardless of the carbon (C) substitution level, indicating larger intragrain scattering because of the simultaneous reaction between Mg and SiC and carbon substitution during the formation of MgB2. In addition, because of the cleaner reaction route for the samples reacted with SiC, the calculated active area that carries current, AF, is twice that of the (Si+C) samples. On the other hand, the upper critical field, Hc2, was similar for both sets of samples despite their different C substitution levels, which proves the importance of defect scattering in addition to C substitution level. Hence, the form of the precursor reactants is critical for tuning the form of Hc2(T)

Hu Shi\u27s "The Greatest Event of Life

胡適による独幕劇「終身大事」は、中国話劇史上、白話で書かれた初めての、そして、本人の選択による結婚の自由をテーマとした最初の作品である。「終身大事」が、その先進的な内容ゆえに上演困難であったことで浮かび上がる現実との矛盾、それはまさに五四時期の現実と理想との距離であり、それゆえにこそ、「家出」という行動の持つ反抗の意味がより深く認識できるともいえる

Bangunan cagar budaya berlanggam Cina di Jakarta

Kawasan pecinan menjadi salah satu ikon yang penting di Jakarta. Keberadaannya tidak dapat dipisahkan dari sejarah perkembangan kota Jakarta di era kolonial hingga kini. Sampai saat ini, eksistensi kawasan pecinan masih kental terasa di beberapa wilayah di belahan Jakarta. Keberadaannya memberi warna keragaman budayai bukota yang menjadi simbol Indonesia min
