Researchers have developed several tests of receptive vocabulary knowledge suitable for use with learners of English, but options are few for learners of French. This situation motivated the authors to create a new vocabulary size measure for French, the Test de la taille du vocabulaire (TTV). The measure is closely modelled on Nation’s (1983) Vocabulary Levels Test (VLT) and follows the guidel...
Alterations of B cell subpopulations have been described up to date as characterizing advanced stage of HIV-1 infection. However, whether such defects are relevant in subjects with a preserved number of CD4⁺ T cells (>350 cells/μL) is unclear. In a cross-sectional study, we investigated if signs of B cells exhaustion and impaired viral immune surveillance are present in a cohort of 43 asymptoma...
The study deals with the handling of thin wafers in 3D integration. It concerns fabrication 300 mm industrial tools. Usually, manufacturing is based on a temporary bonding process performed at 200 °C using thermoplastic adhesive. In that condition bonding, thinning and dismounting are satisfactory. Moreover, adhesive flattening during results an excellent thickness uniformity bonded pairs, smal...
A new species of torque teno mini virus, named TTMV-222, was detected in gingival tissue from periodontitis patients using a viral metagenomics method. The 2803-nucleotide genome of TTMV-222 is closely related to TTMV1-CBD279, with 62.6% overall nucleotide similarity. Genetic analyses of the new virus genome revealed a classic genomic organization but a weak identity with known sequences. The p...
چکید ه سابقه و هدف TTV برای نخستین بار در سال 1997 در خون بیماران ژاپنی با سطوح بالای آلانین ترانسفراز( ALT ) که عاری از دیگر ویروس‌های عامل هپاتیت بودند، کشف شد. به منظور تعیین فراوانی آلودگی به TTV و نقش آن در آسیب‌های کبدی، نمونه‌های سرمی افراد به ظاهر سالم و افراد آلوده به ویروس‌های HBV و HCV از سازمان انتقال خون شهر تبریز تهیه گردید و مورد آزمایش قرار گرفت. مواد وروش‌ها مطالعه ان...
Serum and liver tissues from hepatitis B surface antigen-negative/anti-hepatitis C virus (HCV)-negative (non-B, non-C) hepatocellular carcinoma (HCC) patients in Japan were examined for the presence of hepatitis B virus (HBV), HCV, and TT virus (TTV) by polymerase chain reaction. The studies evaluated the contribution of these viruses to pathogenesis of HCC. HBV DNA was detected in the sera of ...
HIP 41378 f is a temperate $9.2\pm0.1 R_{\oplus}$ planet with period of 542.08 days and an extremely low density $0.09\pm0.02$ g cm$^{-3}$. It transits the bright star (V=8.93), making it exciting target for atmospheric characterization including transmission spectroscopy. was monitored photometrically between dates 2019 November 19 28. We detected transit NGTS, just third ever this planet, whi...
