TL;DR: The ionization equilibrium is calculated for a suppressor effluent containing remnant ions, e.g., Na+ in the case of anion analysis, due to imperfect suppression and it is shown that the remnant ion seriously depresses the peak height of samples of low concentration.

TL;DR: In this paper, a multistate model with different binding energies and electron-lattice couplings is suggested for donor related DX centers in AlGaAs:Sn have been studied by CC-DLTS and constant-capacitance transient.

TL;DR: In this article, the authors collected sediment samples from Jiulong Estuary (Xiamen Harbour, Fujian, China), where five major species of mangrove grow quite well, even though the levels of the heavy metals Cu, Pb, and Hg from anthropogenic sources in the sediments of the region are as high as 18.1 ppm, 59.2 ppm, and 0.14 ppm, respectively.

TL;DR: Photodynamic therapy was studied in the treatment of a variety of solid malignant tumors and it was noted that the lymphatic metastatic foci showed a higher photosensitivity, and the covering skin, connective tissue and the nearby organs were not obviously injured.
Abstract: Photodynamic therapy (PDT) was studied in the treatment of a variety of solid malignant tumors. Ten patients with oral squamous cancers treated by PDT are reported: The laser beam was introduced into the malignant and metastatic lymphatic tissues through inserted optic fibers. The results showed that all the lesions gave complete response to PDT except the bony involvement. It was noted that the lymphatic metastatic foci showed a higher photosensitivity, and the covering skin, connective tissue and the nearby organs were not obviously injured. Combination of PDT with chemotherapy, radiotherapy and surgery are also discussed.

TL;DR: In this paper, the formation of Mn 2+ ion pairs and clusters is the main factor of the luminescence concentration quenching of ZnS:Mn, Cu.

TL;DR: By using selective excitation technique, the phonon sidebands belonged to each NNi pair center were successfully resolved out from the seriously overlapping spectrum under above gap excitation as discussed by the authors, which confirmed that NN1, NN3 and isolated N centers have almost the same phonon structure.

TL;DR: It is revealed that R. salmoninarum has passed through the BKD’s “garden” stage.
Abstract: サケ科魚類の細菌性腎臓病(BKD)原因菌キャリヤーの的確かつ迅速な診断へのFITC標識アビジン・ビオチン抗体(ABC)法の導入を検討し以下のような結論を得た。1. 従来のFAT間接法に比し蛍光発色度はABC法で約1.5倍となり,かなりの発色増強効果が得られた。2. 飼育魚の腎臓塗抹標本を用いてのABC法と従来のFAT間接法によるR. salmoninarumの検出率の比較では,観察時間を3分間とした場合ABC法でFAT間接法の約1.5倍,また従来と同様100視野観察時の比較ではABC法で従来法の約1.4倍となり,蛍光発色度の増強が観察時間を区切った場合の検出率により強く反映された。3. ABC法では蛍光発色度が増加することにより,非特異蛍光も必然的に増加することが予想される。本法の導入に際しては使用する抗血清の反応特異性を前もって十分検討し確認しておく必要があろう。

TL;DR: In this article, the electronic structures, total and partial density of states of II-VI semiconductors were studied using a linear muffin-tin-obital (LMTO) method.
TL;DR: In this paper, an observation of increase in the value of Huang-Rhys factor and energy shift and broadening of emission lines due to excitons bound to Bi traps is reported for the first time.
TL;DR: In this article, the photoluminescence of GaAs0.15P0.85:N has been studied at 77K under hydrostatic pressure, and the NN1 emission was clearly observed when P>10kbar.
Abstract: The photoluminescence of GaAs0.15P0.85:N has been studied at 77K under hydrostatic pressure. The NN1 emission is clearly observed when P>10kbar. This result indicates that pressure enhances the thermally assisted Nx→NN1 exciton transfer. The pressure behaviors of Nx and NN1 levels are analysed.
TL;DR: In this article, the influence of the Bi dopant concentration on the luminescence associated to N, NN i bound excitons and also the effect of N dopant on the luminosity due to Bi bound excITons is analyzed.
TL;DR: In this article, double light sourve photocapacitance (PHCAP) method was used to investigate the deep defects in GaAs 1− x P x (N )/gap (x=0.65, 0.85) and the parameters of deep level (DL) were determined by the PHCAP spectra which were measured at the low temperature (T=100K).

TL;DR: In this paper, the decay properties of GaP(Bi, N) crystals were investigated and the PL spectra at different excitation levels of samples with various Bi concentrations support that there is an energy transfer from N to Bi center, and the time-resolved intensity of Bi BE emission shows that the energy transfer is a very rapid process.
TL;DR: In this article, the photovoltaic spectra of P/N/N + GaP:N were measured by the surface PV-based method and fitted well to theoretical results in this paper.

TL;DR: This article showed that a consumption tax, rather than a tax on wage income, is time-consistent under a variety of circumstances, even including some cases where the optimal tax rate is not constant over time.
Abstract: This paper addresses the time-consistency problem of optimal policy when intertemporal prices are inflexible. For small, open economies facing given world interest rates, it shows that a consumption tax, rather than a tax on wage income, is time-consistent under a variety of circumstances, even including some cases where the optimal tax rate is not constant over time. This result, when it applies, restores the neutrality of the term structure of government debt, and reaffirms the tax-smoothing theory of debt determination.
