超人帮忙 IE愉快使用

相信对于直接使用IE浏览器的朋友来说,比较羡慕Maxthon、GreenBrowser等第三方浏览器的实用功能,借助于一款叫做"IESuper"(又叫"IE超人")的软件,它会使你浏览网页时更加轻松。     

增强版沙箱新版卡巴的安全免疫区

现在的恶意软件或插件程序真是令人防不胜防，稍有不慎就会中招，如果这些来路不明的程序或者恶意网站在沙箱这种“虚拟环境”中运行，就能避免系统受到攻击，卡巴斯基2010全功能安全软件新增的“安全免疫区”功能即可达到沙箱软件的作用。     

不只是看看而已 ACDSee另类妙用

说到大名鼎鼎的看图软件ACDSee,朋友们都不陌生,并且也是常用的软件之一,除了看图、创建PDF和幻灯片以及刻录光盘以外,其实它也能转换"岗位",充当     

亚洲IT战首争人才

虽然不断有网站“爆煲”或裁员，可是亚洲资讯科技（IT人才短缺的情况并没有太大改善，区内各国政府和企业正想尽方法招聘和留住人才，一场关于经济兴衰的IT人才争夺战势必愈演愈烈。     

一不留神，密码送人——即时通讯软件密码撤消保存三板斧

最近接二连三地接到许多同学的“投诉”;在使用QQ和MSN时会经常被告知“该帐号已经在其他位置登录,你被迫下线”。这说明有人在盗用你的QQ、MSN或者是网易泡泡的密码!可这些密码从没告诉过任何人呀,这是怎么回事?又应该怎么办呢?     

Micellar casein gelation at high sucrose content

This article investigates the effect of sucrose addition on the formation of casein gels by acidification and/or renneting of pure micellar casein. Gelation kinetics and gel properties were followed by rheological methods, and microscopy and syneresis measurements were used to obtain a more complete characterization of the structures formed. Sucrose content has been identified as a key parameter for controlling the kinetics of aggregation and the strength of the final gels. Results have shown that the effect of sucrose on gelation can vary such that effects can be completely reversed depending on the gelation route used. During acid gelation, addition of up to 30% (wt/wt) sucrose causes gels to form more rapidly and at higher pH values, and to have higher viscoelastic moduli and a more homogeneous microstructure than those without sucrose. By contrast, gels formed by renneting in the presence of sucrose are weaker and have longer gelation times. It is proposed that sucrose reduces solvent quality and causes the collapse of the "hairy" kappa-casein brush on the surface of the casein micelles. This may explain why sucrose increases the possibility of gel formation during acidification and reduces the degree of kappa-casein hydrolysis during renneting.     

Efficient 550-600-nm tunable laser based on noncritically phase-matched frequency doubling of room-temperature LiF:F2- in lithium triborate

We report on efficient conversion of a 1064-nm Nd:YAG laser to tunable visible light. The conversion scheme uses noncritically phase-matched second-harmonic generation of a pulsed Nd:YAG-pumped LiF:F2- laser in lithium triborate. Optimization yields 42% LiF:F2- laser efficiency and 56% frequency-doubling efficiency, providing >20% conversion from 1064 nm to broadly tunable visible output. A dramatic sensitivity of laser efficiency to pump pulse duration is recorded, with a fundamental efficiency improvement of over 30-fold measured for an increase in pump pulse duration from 5 to 34 ns.     

合并FLV短片TVC也行

从优酷网之类的视频分享网站下载的FLV视频,很多都是分片段上传的,或者采用连续剧分集的形式。尽管KM Player或暴风影音之类播放软件都有"无缝播放"功能,但是看起来还是有点不够连贯和不够爽快的感觉,如何来将这些片段合并成一个整体的视频和合集呢?除了借助于一些FLV合并编辑工具来达到目的以外,其实最常用     

网页浏览和在线视频观看两不误

现在的浏览器基本上都支持多页面(Tab)浏览,大大地提高了浏览效率,但是要想浏览完后接着查看另一页面,就得进行标签切换。在视频分享网站看视频的同时,还想浏览其他网页的话就比较麻烦了。如果你使用的是TT浏览器4.4版本的话就很简单,让你网页浏览与在线视频观看两不误。     

关闭程序窗口何需点小叉

在电脑上进行繁忙的工作,想必会打开很多的工作窗口,其中重复得最多的动作当属关闭和最小化程序窗口,每次都得反复移动鼠标去点击窗口右上角的
