现在攒一台电脑主流配置大概多少钱??
现在攒一台电脑主流配置大概多少钱??其实我想买品牌的,后来听人说品牌电脑里面的硬盘和内存都是杂牌子的,不好,而且显卡什么的也不是很好，所以想攒一台!大哥们出出主意!看看主流配置是个什么样子??价格在4500左右!
我需要补充一下:1.必须是DVD刻录;2.显卡必须是独立,且512M以上.其他的......应该没什么啦,主流配置,家用,最好能跑极品飞车9的!

哎，一大队枪手！！！！！！！！！偶无语。。。。。。
品牌电脑用的可不是杂牌子,但是性能不是很出众,一般都是一些质量好稳定又便宜的件.因为品牌电脑要做售后,还要装正版系统,所有这部分费用加进去就比攒的贵了.攒机器不是适合所有人的,只适合2类人!1.没钱的穷人.2.追求性能的发饶玩家.其他的比如企业用户和普通用户,大可选择品牌机.现在装机器不太明智,虽然你4500的预算还算刚刚够.主流配置一般在左右.所谓的主流,就是当前时期性价比最高的硬件的总汇.你买电脑为了什么?玩游戏还是工作还是学习还是就是上上网?根据需求不同,配置也不同.如果你要个能上网的,外观华丽的给女孩子用,那么不到4000就可以了如果你要追求大容量,追求影音效果,5000才够如果你要玩游戏,那么还是别配了,因为现在支持DX10的卡只有8800,以后WINDOWS下一代vistar出了盗版以后现在硬件都会大跳水.你不希望你买了不久的机器连一年后新出的一款游戏都跑不起来吧.如果非要卡着4500配,那么别考虑以后升级问题了大体配置能是1G内存
主流7300GT显卡160G硬盘17寸液晶(如果放家里不考虑携带问题,那么推荐19寸CRT显示器,虽然大点,但是能用的住,液晶的玩2年屏幕就黑了)AMD 3800+ CPU(玩游戏还是AMD平台好)QQ1.必须是DVD刻录;刻录机不值钱,200-300,应该没问题2.显卡必须是独立,且512M以上. 独立显卡没问题,512M显存有点扯,内存么1G都可以,显存没戏再说显存大不一定就好,这年头看芯片

George W Ordal, University of Illinois at Urbana-Champaign, USA. F1000 Microbiology
In this article, the authors report a new protein, CheS, that enhances the binding of CheA to CheY-1-P to bring about its dephosphorylation in Sinorhizobium meliloti. It is exciting that after this many years, a novel chemotaxis protein has been discovered.
The main response regulator in S. meliloti chemotaxis is CheY2-P. Although all phosphorylated response regulators spontaneously dephosphorylate, in all chemotactic organisms that I am aware of this dephosphorylation is speeded up by catalysis involving other proteins, such as by CheZ in E. coli {1} and CheC or FliY in Bacillus subtilis (see {2}, on which I am a co-author). In the case of S. meliloti, the phosphoryl groups are transferred back to CheA and thence to a different CheY, namely CheY-1, which dephosphorylates. The rate of this dephosphorylation is increased by CheS. As expected, the rate of CheY2-P dephosphorylation, in absence of CheY1, is unaffected by CheS. As determined by surface plasmon resonance spectroscopy, CheY1 binds about 100-fold more strongly to CheA/CheS than to CheA. Limited proteolysis revealed the locus of binding of CheS to CheA to be the N-terminal part of the CheY2 binding domain in CheA. Deletion of cheS has the same phenotype as a deletion of cheY1.

Keith Ray, Richard F. Helm, Birgit E. ScharfIndian Journal of Microbiology, SpringerLinkA simple, inexpensive and effective genomic DNA isolation procedure for Lactobacillus isolates from traditional Indian fermented milk (dahi) is described. A total of 269 Lactobacillus isolates from fermented milk collected from four places in North and west India were tested for lysis by an initial weakening of the Gram positive cell wall with Ampicillin followed by Lysozyme treatment. The average genomic DNA yield was ~50 &#x3g/ml log phase culture. Quality and repeatability of the method was found to be adequate for subsequent molecular applications. The quality of the genomic DNA isolated by this method was verified by restriction digestion and polymerase chain reaction (PCR). No inhibition was observed in subsequent PCR amplification and restriction digestion. The presented method is rapid, cheap and useful for routine DNA isolation from gram positive bacteria such as Lactobacillus.Authors:, , Gurpreet Kaur, Amit Roy, Ramakant Kaushik, Paras Yadav, Rameshwar Singh, Tirtha Kumar Datta, Surender Lal GoswamiInternational Journal of Dairy Technology, WileyA high-performance liquid chromatography method is described for the detection of adulteration of milk with soymilk, based on separation of sugars on NH2 column and their detection by refractive index detector. Sugars were extracted with 20% acetonitrile in the presence of Carrez solutions and quantified. Recovery of added raffinose to soymilk was 96.3%. Owing to relative high concentration of lactose in milk or adulterated milk, lactose peak was very broad and spread to retention time corresponding to sucrose and raffinose. However, stachyose peak remained well separated. Presence of stachyose peak in milk can be used for the detection of adulteration of milk with soymilk and the method can detect upto 5% soymilk in milk.Authors:, , Poonam, Yudhishthir S. Rajput, Sudhir K TomarGeneral and Comparative Endocrinology, ElsevierThe cDNA sequence of leuteinizing hormone (LH) beta subunit was determined to understand the molecular basis for silent oestrus behavior and poor response to superovulation in buffalo. The LH-β cDNA contains an open reading frame 426 bp long. The deduced sequence of the LH-β is 141 amino acids in length. The amino acid sequences of the Indian river buffalo LH-β subunit showed overall similarity to those of other mammals. The nucleotide sequence variability of LH-β was studied in more than ∼350 Indian buffaloes covering five different breeds. The results of the sequence analysis showed that the buffalo LH-β gene is not highly conserved and non-synonymous mutations are not rare, at least in the samples collected randomly from five different breeds and buffalo populations. A total of seven different variants were obtained. In spite of its crucial role in reproduction, variation of the LH-β gene was found present in this species. The polymorphisms found were unique in the Indian river buffalo population.Authors:, Mallikarjuna Shivapura Basavarajappa, , Manish Thakur, Tirtha Kumar Datta, Paras Yadav, Surender Lal GoswamiMilchwissenschaft (Milk Science International), German Association of Dairy ScienceA competitive-binding enzyme linked immunosorbent assay (ELISA) for the estimation of vitamin B12 was evaluated for its applicability in milks from different Indian milking animal species. The detected vitamin B12 levels in milks from cow, buffalo and goat were found to be 4.91, 21.68 and 3.91 ppb, respectively. The reliability of the ELISA method was checked by adding 3 and 6 ppb of vitamin B12 standard (cyanocobalamin) to the raw milk of each species and the recovery was quantitative. Estimation for vitamin B12 by ELISA was found to be simple, reproducible, and the results can be obtained on the same day.Authors:, , Yudhishthir S Rajput, Sudhir K TomarEducationMS, , 3.8Interdepartmental Microbiology Graduate ProgramActivities and Societies:&Phi Sigma Biological Sciences Honor SocietyMSc, , First ClassBSc, , , First ClassCourses Independent CourseworkSS: Advanced Microbial Genetics (BIOL5984)SS: Advanced Microbial Pathogenesis (BIOL5984)Biochemistry for the Life Sciences (BCHM5124)Prokaryotic Gene Regulation (BCHM5054)Computational Biochemistry and Bioinformatics (BCHM5024)Protein Structure and Function (BCHM5224)Seminar in Molecular and Cellular Biotechnology (BIOL5064)Honors & Awards
