“He is ugly and a Jew!“: the Hungarian socialist workers’ party and the Hungarian Jewish community in the 1960s and 1970s
The years 1967 and 1974 seemed especially significant as the anti-Zionistic rage caused by the Israeli-Arab wars stirred up Hungary‘s internal affairs. The anti-Zionist policy adopted by the Kádár regime after 1956 meant more than 'simple' anti-Israel attitude in Hungary. The article provides some answers on the following questions: What characterized the policy of the Hungarian Socialist Workers' Party toward the Hungarian Jewish community? Which strategy did the Jewish Community develop in order to survive as a minority in a closed social and political system? How much was the Community able to represent special Jewish interests in the era of consolidation after 1956? Furthermore the article enrichs the picture on the topic with new documents and features with regard to the relationship of the ruling party to a minority
Relationship Between Traditional and Contemporary Dating Styles and Male Commitment Level
This research aimed at discovering a relationship between dating style and male commitment. I hypothesized that traditional dating, where the male plays the initial active role and couples reserve sexual activity for marriage, would better predict male commitment due to effort justification theory and gain-loss theory. However I also acknowledged a counter hypothesis predicting a correlation between contemporary dating, with blurred gender roles and sexual boundaries, and male commitment due to behaviorist theory. Fifty-seven males took a survey assessing dating style and commitment level to find if either of these relationships existed. After data analysis, I found that female initial passivity, couples similarity in values and beliefs, and establishment of sexual boundaries to have a significant relationship with male commitment

Nocturnal low-level clouds over southern West Africa analysed using high-resolution simulations
We performed a high-resolution numerical simulation to study the development
of extensive low-level clouds that frequently form over southern West Africa
during the monsoon season. This study was made in preparation for a field
campaign in 2016 within the Dynamics-aerosol-chemistry-cloud interactions in West Africa (DACCIWA) project and focuses on an area around the city of
Savè in southern Benin. Nocturnal low-level clouds evolve a few hundred
metres above the ground around the same level as a distinct low-level jet.
Several processes are found to determine the spatio-temporal evolution of
these clouds including (i) significant cooling of the nocturnal atmosphere
caused by horizontal advection with the south-westerly monsoon flow during
the first half of the night, (ii) vertical cold air advection due to gravity
waves leading to clouds in the wave crests and (iii) enhanced convergence and
upward motion upstream of existing clouds that trigger new clouds. The latter
is caused by an upward shift of the low-level jet in cloudy areas leading to
horizontal convergence in the lower part and to horizontal divergence in the
upper part of the cloud layer. Although this single case study hardly allows
for a generalisation of the processes found, the results added to the
optimisation of the measurements strategy for the field campaign and the
observations will be used to test the hypotheses for cloud formation
resulting from this study
Evidence of the Generation of Isosaccharinic Acids and Their Subsequent Degradation by Local Microbial Consortia within Hyper-Alkaline Contaminated Soils, with Relevance to Intermediate Level Radioactive Waste Disposal
The contamination of surface environments with hydroxide rich wastes leads to the formation of high pH (>11.0) soil profiles. One such site is a legacy lime works at Harpur Hill, Derbyshire where soil profile indicated in-situ pH values up to pH 12. Soil and porewater profiles around the site indicated clear evidence of the presence of the α and β stereoisomers of isosaccharinic acid (ISA) resulting from the anoxic, alkaline degradation of cellulosic material. ISAs are of particular interest with regards to the disposal of cellulosic materials contained within the intermediate level waste (ILW) inventory of the United Kingdom, where they may influence radionuclide mobility via complexation events occurring within a geological disposal facility (GDF) concept. The mixing of uncontaminated soils with the alkaline leachate of the site resulted in ISA generation, where the rate of generation in-situ is likely to be dependent upon the prevailing temperature of the soil. Microbial consortia present in the uncontaminated soil were capable of surviving conditions imposed by the alkaline leachate and demonstrated the ability to utilise ISAs as a carbon source. Leachate-contaminated soil was sub-cultured in a cellulose degradation product driven microcosm operating at pH 11, the consortia present were capable of the degradation of ISAs and the generation of methane from the resultant H2/CO2 produced from fermentation processes. Following microbial community analysis, fermentation processes appear to be predominated by Clostridia from the genus Alkaliphilus sp, with methanogenesis being attributed to Methanobacterium and Methanomassiliicoccus sp. The study is the first to identify the generation of ISA within an anthropogenic environment and advocates the notion that microbial activity within an ILW-GDF is likely to influence the impact of ISAs upon radionuclide migration
Activation of the innate immune receptor Dectin-1 upon formation of a 'phagocytic synapse'.
Innate immune cells must be able to distinguish between direct binding to microbes and detection of components shed from the surface of microbes located at a distance. Dectin-1 (also known as CLEC7A) is a pattern-recognition receptor expressed by myeloid phagocytes (macrophages, dendritic cells and neutrophils) that detects β-glucans in fungal cell walls and triggers direct cellular antimicrobial activity, including phagocytosis and production of reactive oxygen species (ROS). In contrast to inflammatory responses stimulated upon detection of soluble ligands by other pattern-recognition receptors, such as Toll-like receptors (TLRs), these responses are only useful when a cell comes into direct contact with a microbe and must not be spuriously activated by soluble stimuli. In this study we show that, despite its ability to bind both soluble and particulate β-glucan polymers, Dectin-1 signalling is only activated by particulate β-glucans, which cluster the receptor in synapse-like structures from which regulatory tyrosine phosphatases CD45 and CD148 (also known as PTPRC and PTPRJ, respectively) are excluded (Supplementary Fig. 1). The 'phagocytic synapse' now provides a model mechanism by which innate immune receptors can distinguish direct microbial contact from detection of microbes at a distance, thereby initiating direct cellular antimicrobial responses only when they are required
Seasonal variations of Saanen goat milk composition and the impact of climatic conditions
The aim of this research was to investigate the effect of climatic conditions and their impact on seasonal variations of physico-chemical characteristics of Saanen goat milk produced over a period of 4 years. Lactation period (early, mid and late) and year were considered as factors that influence physico-chemical composition of milk. Pearson's coefficient of correlation was calculated between the physico-chemical characteristics of milk (fat, proteins, lactose, non-fat dry matter, density, freezing point, pH, titrable acidity) and climatic condition parameters (air temperature, temperature humidity index-THI, solar radiation duration, relative humidity). Results showed that all physico-chemical characteristics of Saanen goat milk varied significantly throughout the lactation period and years. The decrease of fat, protein, non-fat dry matter and lactose content in goat milk during the mid-lactation period was more pronounced than was previously reported in the literature. The highest values for these characteristics were recorded in the late lactation period. Observed variations were explained by negative correlation between THI and the physico-chemical characteristics of Saanen goat milk. This indicated that Saanen goats were very prone to heat stress, which implied the decrease of physico-chemical characteristics during hot summers
