EXPERIMENT STABILITY OF LIQUID COLUMNS (STACO) ON THE ADVANCED FLUID PHYSICS MODULE (FPM) ABOARD SPACELAB-D2

  • Perales Perales, José Manuel

During the second German Mission of Spacelab (1993, Spacelab D-2) an experiment on the mechanical stability of liquid columns was performed. A liquid column is a liquid mass held between to solid (circular) supports. A 30 mm in diameter and 90 mm long liquid drop was stablished in the Advanced Fluid Physics Module (AFPM) and was subjected to different mechanical stimuli (rotation of the supports, oscillation of one of the supports, change in volume and in length) to check whether the resulting drop was stable or not. Results were obtained in terms of images and recorded in a video sequence. Telemetry of the different stimuli and parameter values was also recorded. Objetive: The aim of this experiment was to measure the outer shape deformation of long liquid bridges near their stability limit under microgravity, caused by g-jitters and by some controlled mechanical disturbances (change of geometry, change of volume, rotation and vibration). The liquid used was a silicone-oil 10 times more viscous than water (5 times for the last run). The working length of the liquid column was 85 mm. The two solid supports are made of aluminium, of 30 mm in diameter, with a sharp cutback (30 deg. edge) to prevent liquid spreading over the edges. This choice of geometry allows a direct comparison with other TEXUS experiments where two discs of 30 mm in diameter and 86 mm apart were used to hold a cylindrical liquid column (35 mm discs were used in SL-D1 and 40 mm discs on SL-1). A top priority was to verify the results of a previous experiment performed on SL-D1, and because an equivalent Bond number Bo=0.007 was deduced from this experiment and there was no reason to expect a different behaviour, it was planned, in a second run to make use of unequal discs of 30 mm and 28 mm in a second run to precisely counterbalance the expected deformation and better quantify this effect. Procedures: The actual procedures executed were: -- Run 1: background sensing, disc oscillation at 0.40 Hz, 0.41 Hz, 0.42 Hz and again 0.42 Hz. -- Run 2: background sensing and disc separation until breakage of the column. -- Run 3: background sensing. Results: An example of free oscillations of a liquid column (diameter 30 mm, length 85 mm, volume 60 cc), due to g-jitter, is shown in Video1, recorded during the background sensing phase of Run 2. Video2 shows the breakage of the same column caused by disc separation at constant volume. This experiment enabled to accurately measure the response of the 85 mm-long cylindrical liquid column to a forced axial vibration of one of the supporting discs, and found that it is in very good agreement with theory, and complements other measurements performed in the same flight but with shorter columns by D. Langbein. An achievement is the high accuracy reached in automatic image analysis, of the order of 30 microns in object size (0.1 pixels in the 512*512 image), which represents a great improvement in comparison to the manually digitised hard-prints of previous flights. The more puzzling question left after the experiment is the lack of reproducibility of the steady averaged deformation measurement, perhaps because it is not a characteristic of the configuration and may be dependent on details of hardware (e.g. materials used, rounding of wetted corners) that escape control of the experimenter and are different for each campaign. As usual, more experiments are needed to elucidate the unexpected results of this one, but a clear progress in the overall experiment planning is evident.

FORMAL CONCEPT ANALYSIS FOR TOPIC DETECTION: A CLUSTERING QUALITY EXPERIMENTAL ANALYSIS

  • Castellanos, Angel
  • Cigarrán, Juan
  • Garcia-Serrano, Ana
RepLab is a competitive evaluation exercise for Online Reputation Management systems organized as an activity of CLEF. RepLab 2013 focused on the task of monitoring the reputation of entities (companies, organizations, celebrities, etc.) on Twitter. The monitoring task for analysts consists of searching the stream of tweets for potential mentions to the entity, filtering those that do refer to the entity, detecting topics (i.e., clustering tweets by subject) and ranking them based on the degree to which they signal reputation alerts (i.e., issues that may have a substantial impact on the reputation of the entity). The RepLab 2013 task is defined, accordingly, as (multilingual) topic detection combined with priority ranking of the topics, as input for reputation monitoring experts. The detection of reputational polarity (does the tweet have negative/positive implications for the reputation of the entity?) is an essential step to assign priority, and was evaluated as a standalone subtask, Application of Formal Concept Analysis (FCA), an exploratory technique for data analysis and organization. In particular, we propose an extension of FCA-based methods for topic detection applied in the literature by applying the stability concept for the topic selection. The hypothesis is that FCA will enable the better organization of the data and stability the better selection of topics based on this data organization, thus better fulfilling the task requirements by improving the quality and accuracy of the topic detection process, FCA.tar.gz (about 3MB) This file contains the FCA implementation as well as the input files for the execution The dataset can be downloaded from the official RepLab webpage: http://nlp.uned.es/replab2013/.

DIFFERENT ROLES OF NRF2 AND NFKB IN THE ANTIOXIDANT IMBALANCE PRODUCED BY ESCULETIN OR QUERCETIN ON NB4 LEUKEMIA CELLS.

  • Rubio, Virginia
  • García-Pérez, Ana I.
  • Herráez, Ángel
  • Diez, José Carlos

Measurement of metabolic activity (MTT assay), cell cycle arrest, reactive oxygen species, expression of Nrf2 and NFkB proteins in nucleus and cytosol, expression of superoxide dismutase and lipooxygenase, activity of superoxide dismutase, phosphorilation of Jnk and p38 proteins, all in NB4 leukemia cell line subjected to treatments with esculetin or quercetin.

Esculetin and quercetin are compounds that could change the balance of redox homeostasis. Treatment of NB4 leukemia cells with quercetin or esculetin affected the distribution of pro-inflammatory NFkB p65 in the nucleus and cytosol. This could suggest formation of inhibitory p50 homodimers possibly related with anti-inflammatory response. Lipoxygenase and superoxide dismutase expression were also affected by esculetin and quercetin. All these data support a relevant differential role for NFkB and Nrf2 in antiinflammatory and redox response when apoptosis was induced by esculetin or quercetin in human leukemia NB4 cells.
