The orbital g-factor and the spin-orbit splittings of the first excited state of F-centres are measured in NaCl, NaBr, KBr and KF crystals by observing absorption and magnetic circular dichroism at various temperatures and using the moments method. Our experimental results and others are compared with Harker’s theoretical values. LE JOURNAL DE PHYSIQUE TOME 38, OCTOBRE 1977, Classification Phys...

Pt(acac)2, AgNO3, Cu(acac)2, Fe(acac)2, Pd(acac)2, RhCl3, Co(acac)2 poly(vinylpyrrolidone) (PVP; Mw 8000), were purchased from Alfa Aesar Co.Ltd, and Bi(NO3)2, KI, KBr, KCl, tris (hydroxymethyl ) aminomethane, HCHO solution (37 wt%), formamide, and acetone were purchased from Sinopharm Chemical Reagent Co. Ltd . All the chemicals were analytical grade and used as received without any purificati...

BE-23372M, a new protein tyrosine kinase inhibitor, has been obtained as a reddish orange solid. The compound, C17H12O6, HRFAB-MS: m/z 312.0625 (M)+, is an acidic substance, showing UV (MeOH) lambda max (epsilon) 266 (8,800), 426 nm (20,400), and IR (KBr)vmax 1752(C = O) and 3298(OH) cm-1. The structure of BE-23372M, (E)-3-(3,4-dihydroxybenzylidene)-5-(3,4-dihydroxyphenyl)-2(3H)-fur anone, has ...

When grown in a defined mediumcontaining 0.05% KBr, Saccharothrix aerocolonigenes ATCC 39243 produces a novel bromo analog of rebeccamycin. This new analog, designated bromorebeccamycin, has been isolated from the culture broth and purified by vacuumliquid chromatography and column chromatography. Spectroscopic data demonstrated that bromorebeccamycin has the same structure as rebeccamycin, exc...

Aim: Assessment of right ventricular (RV) function is a challenge, especially in patients with congenital heart disease (CHD). The aim of the present study is to assess whether knowledgebased RV reconstruction, used in the everyday practice of an echo-lab for adult CHD in a tertiary referral center, is accurate when compared to cardiac magnetic resonance (CMR) examination. Subjects and methods:...

The pre-reducing agents for Se speciation analysis were subject to optimize under the online reduction conditions of flow injection-hydride generation atomic absorption spectrometry using 2 M HCl as a carrier solution and 0.3% (w/v) NaBH4 in 0.2% (w/v) NaOH as a reducing agent. For total Se, the pre-reduction of Se6+to Se4+must be completed when optimizing the prereducing conditions using (i) c...

BACKGROUND Significant renal mass reduction induced by 5/6 subtotal nephrectomy (Nx) is associated with a chain of events that culminates in hypertension and chronic kidney disease (CKD). Numerous studies have provided evidence for the role of angiotensin (Ang) II type 1 receptor (AT1R) in the promotion and progression of the disease; however, conflicting results were reported on intrarenal AT1...

It has been shown that Kernel Based Regression (KBR) with a least squares loss has some undesirable properties from robustness point of view. KBR with more robust loss functions, e.g. Huber or logistic losses, often give rise to more complicated computations. In this work the practical consequences of this sensitivity are explained, including the breakdown of Support Vector Machines (SVM) and w...

The publication of volume 12 the Catalogus translationum et commentariorum has opened up a vast field new manuscript material dealing with medieval commentary tradition on Ovid’s Metamorphoses. Among important French commentaries briefly discussed therein is Brussels, KBR 2100. was produced in northern France mid-thirteenth century and to date received little detailed scholarly attention. In th...
