  • Long term preservation of living ovarian tissues is a critical approach in human reproductive medicine as well as in the conservation of rare animal genotypes. Compared to single cell preservation, optimization of protocols for tissues is highly complex because of the diversity of cells responding differently to non-physiological conditions.

  • ]The study was conducted to explore the cryoprotective effect of L-proline on sheep oocyte vitrification. In vitro matured sheep oocytes (n=836) were vitrified by open pulled straw method in vitrification solution consisting of 15 per cent (v/v) DMSO+ 15 per cent (v/v) EG + sucrose (0.5M) + 20 per cent FBS in TCMh (Group I) and 7.5 per cent (v/v) DMSO + 10 per cent (v/v) EG + sucrose (0.5M) + 20 per cent FBS in TCMh supplemented with 2M L-proline (Group II).

  • In this study, HTO was orally administered to rats at the level of 37 kBq (1 mCi) or 370 kBq (10 mCi) to examine tissue distribution and excretion levels. After sacrifice, wet and dry tissue samples were weighed and analyzed for tissue free-water tritium (TFWT) and organically bound tritium (OBT). The mean tissue concentrations of TFWT (OBT) were 30.9 (17.8) and 4.4 (8.1).

  • Shoot tips of five tomato (Lycopersicon esculentum Mill.) genotypes were successfully cryopreserved by droplet vitrification. Recovered plants were studied for genetic stability by two different assays: amplified fragment length polymorphism (AFLP) using 4 primer combinations and sequencing of lycopene β-cyclase gene (LCY-B) from leaves.

  • The area extending between Danube Canal, Danube, New and Old Danube embodies the most dynamic por- tion of Vienna’s stretch of the river. Always considered highly attractive for construction projects, the situation by the water’s edge is strongly enhanced by the inter- sections with the identity-creating urbanistic axis of Wagramer Strasse and the U1 Underground line. Thus the riverside zones are both provided with, and bordered by, signifi cant spatial fi gures and types with high recogni- tion value.

One has only to walk the former industrial district of any large, older city, from New York to San Francisco, to see its physical manifesta- tions. Yet some nagging problems remain.

  • building raised beds. Raised beds have soil a few inches or more higher than the surrounding area, which provides extra rooting depth, and helps the soil drain and warm up in the spring. They’re typically 3 to 4 feet wide, with mulched paths in between, so you walk on the paths and don’t compact the soil in planting areas. Raised bed sides can be made with reused lumber, broken concrete or concrete blocks, recycled plastic lum- ber, or any non-toxic material. (Don’t use treated wood.) You can also make raised beds without sides. Dig a few inches of soil out of...

  • A three gram oven-dried sample of holocellulose was placed in a 250 mL Erlenmeyer flask with a small watch glass cover. The flasks were placed into water bath that was maintained at 20 o C. The sample was then treated with 50 mL of 17.5 percent NaOH and thoroughly mixed for one minute. After the specimen was allowed to react with the solution for 29 minutes, 50 mL of distilled water was added and mixed well for another minute. The reaction continued for five more minutes. The contents of the flask were filtered by aid of...

  • A one-gram, oven-dried sample of extractive-free bamboo was placed in a 150 mL beaker. Fifteen mL of cold sulfuric acid (72 percent) was added slowly while stirring and mixed well. The reaction proceeded for two hours with frequent stirring in a water bath maintained at 20 o C. When the two hours had expired, the specimen was transferred by washing it with 560 mL of distilled water into a 1,000 mL flask, diluting the concentration of the sulfuric acid to three percent. An allihn condenser was attached to the flask. The apparatus was placed in...

  • Is this use of television vital for the community information needs? In R8069, the survey included comment on various sources or means of finding information – about important subjects. Table 6 demonstrates that TV is seen as a source of information although lower ranking in importance than face to face communication, and radio. This is not surprising given the relative ratios of television to radio. What is perhaps slightly surprising is that television as a source is used by as many people (if not slightly more) than newspapers. This may reflect literacy rates....

  • British people have seen a sample of US public broadcasting that has been so bad that it features as a snippet in humorous mainstream programmes. With the exception of the handful of RSLs the impression of the majority of British people is that community based television is so dire that no one will watch it and it has no value. In contrast to the UK, Germany has a significantly better track record, and local stations in the USA do actually form part of a comprehensive service.

  • The experience of community radio emphasises the participation and ownership of the community. There has been a strong role for local radio (private and NGO) and Pro-poor public programming. It is more than likely that there could be reflections from the different types of radio stations in the evolution of television. The private sector, if given the chance, may start a local television station – owned privately but presenting local content in local language.
