This study examined the discrimination of word-final stop contrasts (/p/-/t/, /p/-/k/, /t/-/k/) in English and Thai by 12 listeners who speak Vietnamese as their first language (L1). Vietnamese shares specific phonetic realization of stops with Thai, i.e., unreleased final stop and differs from English which allows both released and unreleased final stops. These 12 native Vietnamese (NV) listeners’ discrimination accuracy was compared to that of the two listener groups (Australian English (AE), native Thai (NT)) tested in previous studies. The NV group was less accurate than the native group in discriminating both English and Thai stop contrasts. In particular, for the Thai /t/-/k/ contrast, they were significantly less accurate than the AE listeners. The present findings suggest that experience with specific (i.e., unreleased) and native phonetic realization of sounds may be essential in accurate discrimination of final stop contrasts. The effect of L1 dialect on cross-language speech perception is discussed.

One hundred sixty-eight multiply substituted 1,4-benzodiazepines have been prepared by a five-step solid-phase combinatorial approach using syn-phase crowns as a solid support and a hydroxymethyl-phenoxy-acetamido linkage (Wang linker). The substituents of the 1,4-benzodiazepine scaffold have been varied in the -3, -5, -7, and 8-positions and the combinatorial library was evaluated in a cholecystokinin (CCK) radioligand binding assay. 3-Alkylated 1,4-benzodiazepines with selectivity towards the CCK-B (CCK2) receptor have been optimized on the lipophilic side chain, the ketone moiety, and the stereochemistry at the 3-position. Various novel 3-alkylated compounds were synthesized and [S]3-propyl-5-phenyl-1,4-benzodiazepin-2-one, [S]NV-A, has shown a CCK-B selective binding at about 180 nM. Fifty-eight compounds of this combinatorial library were purified by preparative TLC and 25 compounds were isolated and fully characterized by TLC, IR, APCI-MS, and 1H/13C-NMR spectroscopy.

Noise-vocoded (NV) speech is often regarded as conveying phonetic information primarily through temporal-envelope cues rather than spectral cues. However, listeners may infer the formant frequencies in the vocal-tract output—a key source of phonetic detail—from across-band differences in amplitude when speech is processed through a small number of channels. The potential utility of this spectral information was assessed for NV speech created by filtering sentences into six frequency bands, and using the amplitude envelope of each band (=30 Hz) to modulate a matched noise-band carrier (N). Bands were paired, corresponding to F1 (˜N1 + N2), F2 (˜N3 + N4) and the higher formants (F3' ˜ N5 + N6), such that the frequency contour of each formant was implied by variations in relative amplitude between bands within the corresponding pair. Three-formant analogues (F0 = 150 Hz) of the NV stimuli were synthesized using frame-by-frame reconstruction of the frequency and amplitude of each formant. These analogues were less intelligible than the NV stimuli or analogues created using contours extracted from spectrograms of the original sentences, but more intelligible than when the frequency contours were replaced with constant (mean) values. Across-band comparisons of amplitude envelopes in NV speech can provide phonetically important information about the frequency contours of the underlying formants.

A fafajok megválasztása döntő jelentőségű az energiatermelő faültetvény tervezésénél, mert csak a termőhelynek megfelelő, gyorsan növő, nagy produkciójú fafajok és fajták jöhetnek számításba. A fajta és termőhelyi kérdések tisztázása érdekében 2011 tavaszán a tangazdaság soroksári területén mintegy 1500 m2-en kísérleti ültetvényt hoztunk létre 5 fűz és 9 nyárfajtával, ill. egyéb kontroll fajtákkal. Vizsgáltuk ezek növekedési erélyét valamint a termőhely talajtani és klimatikus adottságait, továbbá a technológiát és hatékonyságot.

Az antik és a feudális városoktól az ipari forradalommal megjelenő modern metropoliszokon át a posztmodern urbanizált terekig jelentősen átalakult a városokat meghatározó gazdasági szerkezet, miközben ugyanígy megváltozott a gazdaságokat meghatározó városok belső szerkezete is. Korábban a gazdaságilag fejlettebb városok nagyobb népességszámra és jelentősebb befolyásra tettek szert, napjainkban azonban a városnövekedés és a városfejlődés, valamint a városversenyben betöltött pozíció egyre inkább elválnak egymástól. A globális városhierarchia vezető nagyvárosai – akár fogyó népességszámuk ellenére is – még mindig a fejlett világból kerülnek ki, miközben Földünk óriásivá növő, legnagyobb megapoliszait már a világgazdaság (fél)perifériáján kell keresnünk. Ebből következőben a városok fogalmában és az urbanizáció folyamatában számottevő eltéréseket tapasztalhatunk a világ különböző részein. A fejezet elsődlegesen a városok fejlődése és a települések fejlesztése iránt érdeklődők számára ajánlott, de a témakör aktualitása és fontossága miatt szakmegkötés nélkül javasolt minden hallgatónak.

The scope of this study was to determine the prevalence of near misses and complications during pregnancy and the puerperal period, identifying the main clinical and intervention markers and socioeconomic and demographic factors associated with near misses. It involved a cross-sectional, population-based and probabilistic study with multi-stage complex sampling design conducted in Natal, State of Rio Grande do Norte, Brazil. A validated questionnaire was given to 848 women aged 15 to 49 identified in 8,227 households in 60 census sectors. In theanalysis of associations, the Chi-square test applied and calculated the prevalence ratio (PR) with Confidence Interval (CI) of 95% and 5% significance. The prevalence of maternal near misses was 41.1/1000LB, with hospitalization in an Intensive Care Unit (19.1/1000LB) and eclampsia (13.5/1000LB) being the most important markers. The prevalence of complications during pregnancy and the puerperal period was 21.2%. The highest prevalence of near misses was observed in older women, of black/brown race and low socioeconomic status. Conducting population surveys is feasible and may add important information to the study of near misses and the markers highlight the need for enhancing maternal care to reduce health inequality.
