cryopreservation is as an effective way to prevent species extinction risk. in this study, we have investigated the protective effect of different concentrations cryoprotectant and effect of different dilution ratios on sperm motility percent and its motility duration after thaw. for this work dimethyl sulfoxide, methanol and ethylene glycol was used as cryoprotectant, each at concentration of ...

We have constructed Envismo (energy-visualization-mobility), a prototype of a real-time energy-monitoring platform that pairs common mobile Internet devices (Nokia N810 internet tablets) with cheap, readily available environmental sensors and a webbased datastore tied to an existing energy-monitoring network. This allows for the collection of real-time fine-grained environmental and energy usag...

Combinatorial biosynthesis approaches that involve modular type I polyketide synthases (PKSs) are proven strategies for the synthesis of polyketides. In general however, such strategies are usually limited in scope and utility due to the restricted substrate specificity of polyketide biosynthetic machinery. Herein, a panel of chemo-enzymatically synthesized acyl-CoA's was used to probe the prom...

We review the construction of the extender algebra, a Boolean algebra which is due to Woodin, with δ-many generators. The resulting genericity iteration is applied to prove a new Σ1-absoluteness theorem for c.c.c. forcings with ordinal parameters. Additionally we introduce and discuss sets that extend to a class with unique condensation. We analyse the sets that extend to classes with unique co...

We define extender sequences, generalizing measure sequences of Radin forcing. Using the extender sequences, we show how to combine the Gitik-Magidor forcing for adding many Prikry sequenes with Radin forcing. We show that this forcing satisfies a Prikry like condition destroys no cardinals, and has a kind of properness. Depending on the large cardinals we start with this forcing can blow the p...

The aim of the present study was to evaluate the protective effect of L-glutamine (L-Gln) against cryopreservation injuries on boar sperm. In Experiment 1, L-Gln from 20 to 80 mM was evaluated as a supplement for a standard freezing extender (egg yolk - EY - 20%, and glycerol 3%). No significant improvement (P>0.05) was obtained for any post-thaw sperm parameter assessed (objective sperm motili...

In order to present this result, we approach it by proving some preliminary theorems about different forcings which capture the main ideas in a simpler setting. For the entirety of the notes we work with an increasing sequence of large cardinals 〈κn | n < ω〉 with κ =def supn<ω κn. The large cardinal hypothesis that we use varies with the forcing. A recurring theme is the idea of a cell. A cell ...

Today, power line communications (PLC) based WiFi extenders are emerging in the market. By simply plugging an extender to a power outlet, a user can create a second access point which connects to a master AP/router using the power line infrastructure. The underlying belief is that this can enhance the throughput that a user can achieve at certain locations (closer to the extender) and potential...

OBJECTIVE The aim of the present study was to investigate the effects of four equilibration times (2, 4, 8 and 16 hours) and two extenders (tris or Bioxcell®) on cryopreservation of buffalo semen. MATERIALS AND METHODS In this experimental study, split pooled ejaculates (n=4), possessing more than 70% visual sperm motility were divided in two aliquots and diluted in Bioxcell® and tris-citric ...

On-stud assessment of stallion sperm quality can be problematic. A new instrument, the Nucleocounter SP-100, was validated for measuring stallion sperm concentration and viability. It was subsequently used to evaluate sperm viability in Kenney's extender and INRA96. There was a strong correlation between sperm concentrations measured by the Nucleocounter SP-100 and by the Bürker counting chambe...
