Cheddar cheese was made using control culture (Lactococcus lactis subsp. lactis), or with control culture plus a galactose-metabolising (Gal+) or galactose-non-metabolising (Gal-) Streptococcus thermophilus adjunct; for each culture type, the pH at whey drainage was either low (pH 6.15) or high (pH 6.45). Sc. thermophilus affected the levels of residual lactose and galactose, and the volatile compound profile and sensory properties of the mature cheese (270 d) to an extent dependent on the drain pH and phenotype (Gal+ or Gal-). For all culture systems, reducing drain pH resulted in lower levels of moisture and lactic acid, a higher concentration of free amino acids, and higher firmness. The results indicate that Sc. thermophilus may be used to diversify the sensory properties of Cheddar cheese, for example from a fruity buttery odour and creamy flavour to a more acid taste, rancid odour, and a sweaty cheese flavour at high drain pH.

This article analyses performance consumptions among young people. The theme is explored along two main axes. The first concerns the social heterogeneity in this field, considered on two levels: the different purposes for those investments - cognitive/mental and physical performance; and the different social contexts - university and work - where performance practices and dispositions may be fostered. The second axis explores the roles of pharmacological and natural consumptions, and their interrelationship, in the dissemination of these practices. The empirical data for this analysis were drawn from an ongoing research project on performance consumptions among young people (aged 18-29 years) in Portugal, including both university students and young workers without university education. The results correspond to the stage of extensive research, for which a questionnaire was organised at a national level, using non-proportional quota sampling. On the one hand, they show that (a) there is a hierarchy of acceptance of consumptions according to their purposes, with cognitive/mental performance showing higher acceptance and (b) both pharmaceuticals and natural products are consumed for every type of performance investment. On the other, the comparison between students and workers introduces a certain heterogeneity in this general backdrop, both in terms of the purposes for their consumptions and their opting for natural or pharmacological resources. These threads of heterogeneity will prompt a discussion of the dynamics of pharmaceuticalisation within the field of performance, in particular how therapeutic cultures may be changing in terms of the way individuals relate to medications, expanding their uses in social life.

The purpose of this study is to explore attitudes and practices regarding their heritage language and the dominant English language among Korean American immigrant families. Using the framework of Language Ideology (Silverstein, 1979), I had three research questions: a) why do parents send their children to a Korean language school, b) what attitudes do immigrant parents and their children show toward Korean and English, and c) how are the parents and children involved in the practices of these two languages? I conducted a survey of parents whose children attended a Korean language school in Urbana-Champaign, Illinois, where the number of Korean sojourners (temporary residents) exceeds that of Korean immigrants. Forty participant parents provided demographic information. They described their children's language-use patterns depending on interlocutors as well as their language proficiency in both Korean and English. The reasons for sending their children to the Korean language school were significantly different depending on the respondents' residential status. In comparison to the sojourners, immigrants tended to give more priority to their children's oral language development and Korean identity construction. I also conducted case studies of three Korean immigrant families with 3- to 5-year-old children, using interviews, observations, and photographs of children's work. The collected data were analyzed according to themes such as daily life, parental beliefs about two languages, practices in two languages, children's attitudes toward two languages, and challenges and needs. Despite individual families' different immigration histories, the three families faced some common challenges. Because of their busy daily routines and different lifestyles, the immigrant families had limited interactions with other Koreans. The parents wanted their children to benefit from two communities and build a combined ethnic identity as Korean Americans. I argue that a Korean language school should expand its role as a comfort zone for all Koreans and Korean Americans. This study explores the heterogeneity among Korean sojourner and immigrant families and their language use and identity construction.

In this study, Dicentrarchus labrax encephalitis virus (DIEV), which causes sea bass encephalitis, was propagated in cell culture, thus allowing study of its lytic cycle, DIEV infection of mammalian and fish cells induced different patterns of expression of capsid proteins, which were assembled as virus-like particles, accumulating in the cytoplasm either as diffuse masses or in vesicles, as shown by electron microscopy, These particles correspond to virions, as shown by their ability to induce Secondary infection, Fish cells proved to be more permissive for DIEV than mammalian cells, although virus yield remained low, RNA analysis of infected sea bass cells revealed DIEV RNA3, in addition to genomic RNA1 and RNA2, and the presence of the RNA;! minus strand, thus demonstrating the replication of the DIEV genome, In addition, DIEV RNA-dependent RNA polymerase was associated with mature virions even after purification by a CsCl gradient, but it was dissociated when capsids were destabilized, In addition to providing more information about the relatedness of DIEV to the members of the family Nodaviridae, this study shows that fish nodaviruses may not be able to infect as wide a variety of cells as insect nodaviruses can.

The paper discusses the 2010-2015 studies of the radiocarbon chronology of Podolia ‘barrow cultures’ on the left bank of the middle dniester . The studies have relied on series of 14 C dates for the Klembivka 1, Pidlisivka 1, Porohy 3a and Prydnistryanske 1 sites determined in Kyiv and Poznań laboratories . They are the first attempt to construct a regional (‘Yampil’) radiocarbon scale for ‘Early Bronze’ funerary rites (4th/3rd-2nd millennium BC) as practised by barrow builders – the communities of the Tripolye and Yamnaya cultures – and the secondary barrow users – the designers of necropolises located on barrows – belonging to the Catacomb, Babyno and Noua cultures.
