Aim: Epididymal proteins are known to play an important role in the maturation of spermatozoa, we ought to deter-mine if there are regional differences in androgen-dependent epididymal proteins. Methods: A group of adult rats wascastrated and epididymides were removed three days following castration. The epididymides were dissected into caput,corpus and cauda segments, homogenized, and proteins were fractionated by anion exchange HPLC. Proteins in select-ed fractions were resolved by sDs-PAGE and visualized by silver staining. Results: It was observed that the levels ofmultiple proteins drastically reduced in the various regions of epididymis of the orchiectomized rats. Conclusion: Theepididymal proteins appear to be useful markers to study androgenic action in the epididymis.

Our overall research aim was to examine whether people distinguished between the spatial footprint and carbon footprint of different energy sources, and whether their overall “worry” about energy types was related to future developed of these types. We surveyed 451 people within a university community regarding knowledge about different energy sources with regard to renewability and spatial and carbon footprints and attitudes about which energy type(s) should be developed further. Findings were: 1) Gas, oil and coal were rated as the least renewable, and wind, solar and hydro as the most renewable;2) Oil and coal were rated as having the largest carbon footprint, while wind, solar and tidal were rated the lowest;3) There were smaller differences in ratings for spatial footprints, probably reflecting unfamiliarity with the concept, although oil and gas were rated the highest;4) Energy sources viewed as renewable were favored for future development compared with non-renewable energy sources, and coal and oil were rated the lowest;5) Worry-free sources such as solar were favored;and 6) There were some age-related differences, but they were small, and there were no gender-related differences. Overall, subjects knew more about carbon footprints than spatial footprints, generally correctly identified renewable and non-renewable sources, and wanted future energy development for energy sources which were less worried about (e.g. solar, wind). These perceptions require in-depth examination in a large sample from different areas of the country.

If you are still struggling to get a clear understanding of exactly what Web 2.0 means and how the current hype surrounding social networking and information sharing websites are relevant to your company＇s needs, fear not. Web 2.0, the catch-all term that is most commonly applied to the huge slew of new usergenerated websites made famous by Wikipedia, Myspace, Craiglist and others, has been joined by an even newer buzzword that takes the latest generation of Internet technology firmly into the business arena： Enterprise 2.0.

In this paper, we propose a multi-source multi-path video streaming system for supporting high quality concurrent video-on-demand (VoD) services over wireless mesh networks (WMNs), and leverage forward error correction to enhance the error resilience of the system. By taking wireless interference into consideration, we present a more realistic networking model to capture the characteristics of WMNs and then design a route selection scheme using a joint rate/interference-distortion optimiza- tion framework to help the system optimally select concurrent streaming paths. We mathematically formulate such a route selec- tion problem, and solve it heuristically using genetic algorithm. simulation results demonstrate the effectiveness of our proposed scheme.

This paper explores the prospects for a global carbon market as the centerpiece of any serious attempt to reach the ambitious goal for greenhouse gas (GHG) reductions set by climate scientists. My aim is to clarify the extent to which we know what policy might best support global decarbonisation. We begin by discussing what we might mean by a global carbon market and its theoretical properties. We then go on to discuss the EU Emissions Trading system experience and the recent experience with the Australian carbon tax. Next, we assess recent carbon market initiatives in the Us and in China. My argument is that while establishing the amount of emissions required and dividing it up acceptably between countries requires an enormous scientific and international negotiations effort, the economic instruments to deliver the agreed targets are readily at hand.

While creating a lasting peace process in the Middle East,particularly between Israel and the Arab world,and more specifically with Palestine,has a history of more than 2000 years,this article outlines its history from Theodore Herzl’s famous 1896 statement about the“Jewish state”to the present *** article’s emphasis is on gaining new intercultural understandings through reading the discourse that developed over more than a century on the peace *** discourse,on one hand,is speaker/Author-message-channels-and audience-centered,persuasive,and *** the other hand,discourse analysis is descriptive and text oriented,established by setting frames for speaker/author involvement in the discourse,and is always contextual in its *** both of these formats of analysis,this article explores michael Prosser’s personal readings on discourse from several different perspectives,the Israeli discourse,Palestinian discourse,Arab discourse,and western discourse,tracing the history of this aspect of the Middle East peace process from Herzl’s statement to 2011,a historical period of one hundred and five years.A positive result of reading this discourse is a challenge to offer new intercultural understandings,or a“dialogue among civilizations.”
