A wine market and marketing analysis of Wine Specialities from the Tokaj-Hegyalja Wine District

Tokaj Wine Specialities have few competitors and enjoy a rare niche among natural dessert wines since traditions surrounding their preparation, their specific microclimate, and unique taste enable one to utilise marketing tools for branding and market placement. To elaborate the marketing strategy, one needs market information that adequately shows the current situation and trends. During my research, I carried out segmentation for Tokaj Wine Specialities consumers and illustrated the correlations with statistical methods. My research covered the North-Alföld Region and Budapest. I performed a reliability test on the research databases and demonstrated that the areal data set can be integrated. My hypotheses findings also constitute new research.wine marketing, dessert wine market, market segmentation, consumer behaviour, Food Consumption/Nutrition/Food Safety, Institutional and Behavioral Economics, Marketing, Research Methods/ Statistical Methods,

The Swr1 chromatin-remodeling complex prevents genome instability induced by replication fork progression defects.

Genome instability is associated with tumorigenesis. Here, we identify a role for the histone Htz1, which is deposited by the Swr1 chromatin-remodeling complex (SWR-C), in preventing genome instability in the absence of the replication fork/replication checkpoint proteins Mrc1, Csm3, or Tof1. When combined with deletion of SWR1 or HTZ1, deletion of MRC1, CSM3, or TOF1 or a replication-defective mrc1 mutation causes synergistic increases in gross chromosomal rearrangement (GCR) rates, accumulation of a broad spectrum of GCRs, and hypersensitivity to replication stress. The double mutants have severe replication defects and accumulate aberrant replication intermediates. None of the individual mutations cause large increases in GCR rates; however, defects in MRC1, CSM3 or TOF1 cause activation of the DNA damage checkpoint and replication defects. We propose a model in which Htz1 deposition and retention in chromatin prevents transiently stalled replication forks that occur in mrc1, tof1, or csm3 mutants from being converted to DNA double-strand breaks that trigger genome instability

Mission Operations Centers (MOCs): Integrating key spacecraft ground data system components

In an environment characterized by decreasing budgets, limited system development time, and user needs for increased capabilities, the Mission Operations Division (MOD) at the National Aeronautics and Space Administration Goddard Space Flight Center initiated a new, cost-effective concept in developing its spacecraft ground data systems: the Mission Operations Center (MOC). In the MOC approach, key components are integrated into a comprehensive and cohesive spacecraft planning, monitoring, command, and control system with a single, state-of-the-art graphical user interface. The MOD is currently implementing MOC's, which feature a common, reusable, and extendable system architecture, to support the X-Ray Timing Explorer (XTE), Tropical Rainfall Measuring Mission (TRMM), and Advanced Composition Explorer (ACE) missions. As a result of the MOC approach, mission operations are integrated, and users can, with a single system, perform real-time health and safety monitoring, real-time command and control, real-time attitude processing, real-time and predictive graphical spacecraft monitoring, trend analysis, mission planning and scheduling, command generation and management, network scheduling, guide star selection, and (using an expert system) spacecraft monitoring and fault isolation. The MOD is also implementing its test and training simulators under the new MOC management structure. This paper describes the MOC concept, the management approaches used in developing MOC systems, the technologies employed and the development process improvement initiatives applied in implementing MOC systems, and the expected benefits to both the user and the mission project in using the MOC approach

Energetic Ion Bombardment of Ag Surfaces by C60+ and Ga+ Projectiles

The ion bombardment-induced release of particles from a metal surface is investigated using energetic fullerene cluster ions as projectiles. The total sputter yield as well as partial yields of neutral and charged monomers and clusters leaving the surface are measured and compared with corresponding data obtained with atomic projectile ions of similar impact kinetic energy. It is found that all yields are enhanced by about one order of magnitude under bombardment with the C60+ cluster projectiles compared with Ga+ ions. In contrast, the electronic excitation processes determining the secondary ion formation probability are unaffected. The kinetic energy spectra of sputtered particles exhibit characteristic differences which reflect the largely different nature of the sputtering process for both types of projectiles. In particular, it is found that under C60+ impact (1) the energy spectrum of sputtered atoms peaks at significantly lower kinetic energies than for Ga+ bombardment and (2) the velocity spectra of monomers and dimers are virtually identical, a finding which is in pronounced contrast to all published data obtained for atomic projectiles. The experimental findings are in reasonable agreement with recent molecular dynamics simulations

Influencer Marketing

Social media started as a group of platforms where the main goal was to socialize, post pictures, videos, and update your current thoughts, feelings, and location. Over time, social media platforms have begun to expand the type of activities they offer. Thus, social media has become a new alternative for marketing activities provided by various companies. One of the latest online marketing techniques is called Influencer Marketing. This article presents the analysis of several specialized articles, as well as the results of research conducted in this field. It further highlights the current state of knowledge about influencer marketing, the role of influencers in social media, as well as possibilities for future research studies

Tinigible Body Macrophages in Regulation of Germinal Center Reactions

Tingible body macrophages (TBM), long thought simply as scavengers of apoptotic lymphocytes, are located in the unique microenvironment of germinal centers in close proximity to antigen-retaining follicular dendritic cells (FDC). Observations that TBM endocytose FDC-iccosomal (immune-complex coated bodies) antigen suggested that TBM might present this antigen and help regulate the germinal center reaction. To test for antigen presentation, the ovalbumin (OVA)-specific TH hybridoma, 3DO-54.8, which produces IL-2 on receiving effective presentation of OVA, were used as responders to OVA-bearing TBM. Results showed that OVA-bearing TBM failed to induce IL-2 production. Furthermore, addition of TBM to IL- 2-inducing positive controls (B cells) not only failed to augment IL-2 production, but rather TBM significantly (55-90%) reduced B-cell induction of IL-2. We found that TBM were rich in prostaglandin by comparison with other nongerminal center lymph node macrophages and that addition of indomethacin to the cultures reversed the inhibitory effect of TBM. Depletion of TBM from enriched preparations, prior to addition to positive control cultures, also abrogated the inhibitory effect on IL-2 production. These data support the concept that TBM, within the unique microenvironment of germinal centers, may be specialized to downregulate the germinal center reaction

DNA methylation-associated colonic mucosal immune and defense responses in treatment-naïve pediatric ulcerative colitis

Inflammatory bowel diseases (IBD) are emerging globally, indicating that environmental factors may be important in their pathogenesis. Colonic mucosal epigenetic changes, such as DNA methylation, can occur in response to the environment and have been implicated in IBD pathology. However, mucosal DNA methylation has not been examined in treatment-naïve patients. We studied DNA methylation in untreated, left sided colonic biopsy specimens using the Infinium HumanMethylation450 BeadChip array. We analyzed 22 control (C) patients, 15 untreated Crohn’s disease (CD) patients, and 9 untreated ulcerative colitis (UC) patients from two cohorts. Samples obtained at the time of clinical remission from two of the treatment-naïve UC patients were also included into the analysis. UC-specific gene expression was interrogated in a subset of adjacent samples (5 C and 5 UC) using the Affymetrix GeneChip PrimeView Human Gene Expression Arrays. Only treatment-naïve UC separated from control. One-hundred-and-twenty genes with significant expression change in UC (> 2-fold, P < 0.05) were associated with differentially methylated regions (DMRs). Epigenetically associated gene expression changes (including gene expression changes in the IFITM1, ITGB2, S100A9, SLPI, SAA1, and STAT3 genes) were linked to colonic mucosal immune and defense responses. These findings underscore the relationship between epigenetic changes and inflammation in pediatric treatment-naïve UC and may have potential etiologic, diagnostic, and therapeutic relevance for IBD

Histochemical demonstrations of actinomycininduced changes of certain oxidative and hydrolytic enzymes of rat incisor pulps

Levels of succinic and lactic dehydrogenases, cytochrome oxidase, alkaline and acid phosphatase activities of the rat incisor pulp were examined following a sublethal dose injection of actinomycin D. Control animals injected with physiological saline were pair-fed.Succinic dehydrogenase and cytochrome oxidase activities were low in the pulp and presented insignificant alterations throughout the experiment. Lactic dehydrogenase and alkaline phosphatase activities of the dental pulp dropped rapidly during the first several days of the experiment and returned to the normal level by the end of the third week. Acid phosphatase activity showed rapid recovery after an initial drop, reached a peak on day 7, and returned to normal by the end of the second week.The significant increase in acid phosphatase activity occurred at the time when cytoplasmic degenerations are most pronounced. While succinic dehydrogenase and cytochrome oxidase activities remained constant during theexperiment, the normally higher lactic dehydrogenase activity showed a marked reduction in the experimental animals suggesting the dependence of pulp cells on anaerobic glycolysis, which is suppressed by actinomycin D. Variations in the level of enzyme activities observed in control animals are attributed to pair-feeding. Results of the present work give further supports to data obtained from previous ultrastructural studies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33370/1/0000768.pd
