Power turbine gas exit temperature 475°C Design wind speed 53 m/s Material of construction Stainless steel AISI 316L From the turbine exhaust flow and system pressure loss limitations the duct internal diameter was sized at 2 m. Under maximum flow and temperature conditions the mean gas velocity in this duct is 60 m/s. Previous work on free- standing exhaust systems had highlighted the lack of a comprehensive standard that covered the structural aspects of such a system. Further investigations for this project confirmed this situation. The most applicable standard is BS4076 (1978). This specification offers guidelines for the design of freestanding chimneys, but has definite limitations. The most serious of these with respect to this design is that it makes no allowance for nonrigid foundations. The empirical formulae used are also based entirely on using carbon steel as the construction material. It is not clear what modifications would be needed to make these formulae applicable to stainless steels or other metallic alloys.

BÁO CÁO KHOA HỌC SNP HIGH THROUGHPUT SCREENING IN GRAPEVINE USING THE DOCX

Assay design Allele-specific probes and optimized multiplexed assays using the SNPs of interest were designed by an automated multi-step pipeline [20]. These steps include: (1) entering the sequence containing target SNPs; (2) checking for for- matting errors such as non-target polymorphisms near the target SNP or sequence motifs incompatible with the assay; (3) submitting the SNPs that passed the format check for the assay design. The ABI probe design prevents self-complementarity and dimerization, and annealing efficiencies are optimized for ligation. Furthermore, the optimal combination of SNPs to produce the highest yield per multiplex reaction is determined.

LANGUAGE IN THE USA PART 7 POT

Challenge No. 4 : Bilingual education is little more than a jobs program for bilingual teachers and bilingual researchers (see, e.g., Porter 1990: 73). The response : This is a strange and illogical allegation with no basis in reality. Is American education itself a jobs’ program for teachers, school administrators, and educational researchers? A comparison of the student and teacher demographics of US schools reveals that, if anything, we ought to be troubled by the glaring mismatch in their backgrounds. Teachers are overwhelmingly white, middle class, and female. American students are not. Roughly a third of all students in US schools are minorities, while the proportion of teachers belonging to minority ethnic groups was just 13 percent ( Schools 1996). While no one would argue that teachers and students must match in cultural, ethnic, or linguistic backgrounds, it is difficult to understand why anyone would object to teachers who have the skills and background to address the special needs of the students they are teaching. LEP students have special linguistic needs, and there are a great many students in US schools who require teachers who have special skills and training to work with them. At present, there are around 2.75 million school-age children who are limited in English proficiency in US schools. Only 29 percent of public school teachers who have LEP students in their classes are qualified to work with them (Issue 1996), and fewer still have the language background and qualifications to provide native language support for their students. In California, where LEP children are most heavily concentrated, the situation is somewhat better, but there has been a serious shortage of teachers who have the qualifications and preparation to work with children who do not speak English.

ADVANCES IN VIBRATION ANALYSIS RESEARCH PART 10 PPT

6.2.4 Study on new shock absorber Along with the deepening of the research on shock absorber, many new shock absorbers have appeared. Several typical kinds are listed as below: Yan Jiabin [82] proposed an elastic metal shock absorber, which fixed two disks connected with elastic materials at the ends of the crankshaft. disks are tightened in the way that one disk rotates in the opposite direction of the other disk (see figure 10). If loosen both disks simultaneously, they will complete torsional vibration with low amplitude, till stop. At this moment, one section of the shaft rotates in one direction, and another section of the shaft rotates in the other direction. In this case, one end face of the crankshaft will produce displacement. Due to the effect of vibration absorption, the vibration will proceed with reduced amplitude but constant speed, which depends on the internal friction or delayed quantity of elastic material. There are three kinds of elastic shock structure of shock absorber: welding metal elastic elements, combination elastic metal components and welding-combination elastic metal elements. Welding-combination elastic metal elements consist of driving and inertia members that connect each other with elastic material. This kind of shock absorber is suitable for application with simple structure and convenient maintenance.

Studies on the operational parameters of sugarcane harvesting blades

In India, there is a need for a small scale sugarcane harvesting machine which can be used by small and marginal farm holders. The present work has been taken to develop a suitable harvesting machine/ attachment which can be power tiller attached and operated by a multi -purpose tool carrier; for the small and marginal farmers. The developed test set up consisted of a vertical rotor shaft for holding the cutting blade to achieve desired height of cut of cane, the bevel gear unit, the power drive and frame work.

THE VECTOR AND STACK CLASSES

A ListIterator permits you to go forward and backward through the elements, too. Multidimensional Vectors (Vectors of Vectors) No special support is needed to provide multidimensional vectors. Since each element of a vector can be any object type, simply create the appropriate structure first: one vector for the first dimension, and individual vectors for each element of the second dimension. For instance, in order to create a vector of four vectors (where each internal vector contains four elements), you would need to create five vectors before ever putting anything inside. Be sure you truly need the dynamic growth nature of vectors before doing this—there is a lot of overhead involved here. The code also can look ugly when you fetch an element from a multidimensional vector. For instance, the following example would get the element at what might look like array[3][2], if using an array:

HARDWARE AND COMPUTER ORGANIZATION P11 PPSX

ARM does not manufacture chips in its own right. It licenses its chip designs to partners such as VLSI Technology, Texas Instruments, Sharp, GEC Plessey and Cirrus logic who incorporate the ARM processors in custom devices that they manufacture and sell. It was ARM that created this model of selling Intellectual Property, or IP, rather than a silicon chip mounted in a package. In that sense it is no different then buying software, which, in fact, it is. A customer who wants to build a system-on-silicon, such as a PDA/Cell phone/Camera/MP3 player would contract with VLSI technology to build the physical part. VLSI, as an ARM licensee, offers the customer an encrypted library in a hardware description language, such as Verilog. Together with other IP that the customer may license, and IP that they design themselves, a Verilog description of the chip is created that VLSI can use to create the physical part. Thus, you can see with the emergence of companies like ARM, the integrated circuit design model predicted by Mead and Conway has come true.

Analytic framework on parameter ranking for hybrid TIG MAG arc welding of mild steel

Hybrid approach advocates combining two or more traditional technologies to overcome the limitations of the conventional practice. The devised Hybrid TIG MAG arc welding process with the help of an indigenous fixture overcomes the shortcomings of the conventional arc welding. The success of any hybrid technology depends on synergistic parameter interactions which demand a rigorous process control through parameter optimization. The devised process is controlled by 13 major parameters. Optimization of all the process controlling parameters is a resource consuming activity. This study manifests an analytic framework as a combination of hierarchical and networking decision making algorithms, which seeks input on parameter effects and their ranges arrived at through experimentation and gives a ranked or prioritized list of process controlling parameters as an output. The framework identifies 5 critical parameters responsible for the 62% of the parameter interactions which need to be optimized based on the application or the job at hand. The remaining 8 parameters responsible for the balance 38% of the parameter interactions have been stabilized through experimentation once for all process variations irrespective of the application or the job at hand. The study works on the merger of the process optimization and the process prioritization techniques.

Hence, the received signals are time-varying and the traditional range- Doppler algorithm will not be appropriate. Since the concept of range-instantaneous-Doppler algorithm was proposed recently, this algorithm is based on the assumption that the received signals of the scatters are multicomponent linear frequency-modulated signals.

The scope of a variable describes where the vari- able is visible in the program; that is, where it can be used in the program. Variables declared outside of functions are global in scope, meaning they can be used or changed anywhere in the program. A variable is also global if declared within a function unless it is declared within a function with the var keyword.

HISTORY OF THE UNITED STATES CHARLES A BEARD PART 2 DOC

Of the generals who served under him, none can really be said to have been experienced military men when the war opened. Benedict Arnold, the unhappy traitor but brave and daring soldier, was a druggist, book seller, and ship owner at New Haven when the news of Lexington called him to battle. Horatio Gates was looked upon as a "seasoned soldier" because he had entered the British army as a youth, had been wounded at Braddock's memorable defeat, and had served with credit during the Seven Years' War; but he was the most conspicuous failure of the Revolution. The triumph over Burgoyne was the work of other men; and his crushing defeat at Camden put an end to his military pretensions. Nathanael Greene was a Rhode Island farmer and smith without military experience who, when convinced that war was coming, read Cæsar's Commentaries and took up the sword. Francis Marion was a shy and modest planter of South Carolina whose sole passage at arms had been a brief but desperate brush with the Indians ten or twelve years earlier. Daniel Morgan, one of the heroes of Cowpens, had been a teamster with Braddock's army and had seen some fighting during the French and Indian War, but his military knowledge, from the point of view of a trained British officer, was negligible. John Sullivan was a successful lawyer at Durham, New Hampshire, and a major in the local militia when duty summoned him to lay down his briefs and take up the sword. Anthony Wayne was a Pennsylvania farmer and land surveyor who, on hearing the clash of arms, read a few books on war, raised a regiment, and offered himself for service. Such is the story of the chief American military leaders, and it is typical of them all. Some had seen fighting with the French and Indians, but none of them had seen warfare on a large scale with regular troops commanded according to the strategy evolved in European experience. Courage, native ability, quickness of mind, and knowledge of the country they had in abundance, and in battles such as were fought during the Revolution all those qualities counted heavily in the balance.

Construction of phylogenetic tree Based on 16S rDNA sequences of valid strains obtained from EZ-taxon, National Centre for Biotechnology Identification (NCBI) and Rhibosomal Database Project (RDP) sequence database a phylogenetic tree of SD/B strain was made (Fig. 2). The evolutionary history was inferred using the Maximum Parsimony method. Tree #1 out of 2 most parsimonious trees (length = 479) is shown. The consistency index is (0.697674), the retention index is (0.666667), and the composite index is 0.648573 (0.465116) for all sites and parsimony-informative sites (in parentheses). The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (100 replicates) are shown next to the branches (Felsenstein, 1985). The MP tree was obtained using the Sub-tree-Pruning-Regrafting (SPR) algorithm (Nei and Kumar, 2000) with search level 1 in which the initial trees were obtained by the random addition of sequences (10 replicates). The analysis involved 8 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 1329 positions in the final dataset.

Once again, I’ve prepared a bitmap for each of the images in a new resource file, which is included in the project thanks to Delphi 5’s improved Project Manager. Recall that when using resources, the code tends to be faster than when using separate files, and again, we end up with a single executable file to distribute.

To implement the functionality required by the CustomerInformationChanged event, the object needs to implement three read-only properties: Id, NewText, and OldText. Because the properties are read-only, the properties can’t have their values set from code. So, the code sets the properties’ underlying variables in the object’s con- structor, which must be passed the three values that the properties return. In the constructor, the code sets three module-level variables that the corresponding properties return from the data passed to it. In Visual Basic 2005 the event arguments object looks like this:

A variety of DCSs are available today, as shown in Figure 6.9. Typically, these DCSs have hundreds to thousands of ports. The term grooming refers to the grouping together of traffic with similar destinations, quality of service, or traffic type. It includes multiplexing of lower-speed streams into high-speed streams, as well as extracting lower-speed streams from different higher-speed streams and combining them based on specific attributes. In this context, the type of grooming that a DCS performs is directly related to the granularity at which it switches traffic. If a DCS is switching traffic at granularities of DS1 rates, then we say that it grooms the traffic at the DS 1 level. At the bottom of the hierarchy is a narrowband DCS, which grooms traffic at the DS0 level. Next up is a wideband DCS, which grooms traffic at DS1 rates, and then a broadband DCS, which grooms traffic at DS3/STS-1 rates. These DCSs typically have interfaces ranging from the grooming rate to much higher-speed interfaces. For instance, a wideband DCS will have interfaces ranging from DS1 to OC-12, while a broadband DCS will have interfaces ranging from DS3 to OC-48 or OC-192. Today we are also seeing a new generation of DCSs that groom at DS3 rates and above, with primarily high-speed optical interfaces. While such a box could be called broadband DCS, it is more commonly called an optical crossconnect.

BÁO CÁO LÂM NGHIỆP CHANGES IN THE MYCORRHIZAL STATUS OF SOME MOUNTAIN SPRUCE FORESTS POTX

Forestry and Game Management Research Institute, Jíloviště-Strnady, Czech Republic AbstrACt : In the present study, the defoliation status of spruce stands is related to mycorrhizal conditions and presence of mycorrhizal macromycetes fungi in two localities at the highest sites of the Krkonoše Mts. In the long- term view, the defoliation and the diversity of mycorrhizal fungi have improved but the number of active as well as nonactive mycorrhizae has decreased while their ratio has not changed. Statistically significant is the correlation be- tween the total number of mycorrhizae and pH. The results within last years of observations as well as in comparison to the conditions in the last decade show that mountain spruce stands growing at non-exposed sites are tolerant to a degradation of mycorrhizal conditions resulting from the long-term air pollution impact. The studied parameters of mycorrhizal symbiosis have not shown a clear trend; their results however indicate the stabilized mycorrhizal state. Positive changes can be seen in the total increase of macromycetes diversity as well as in the apparent increase of percentage of macromycetes in the studied localities, which correlates to the moderately improving defoliation.

Báo cáo hóa học: " Preparation and thermal conductivity of CuO nanofluid via a wet chemical method" potx

Preparation of stable nanofluids is the first step and key issue of nanofluid research and applications. At present, some methods, such as dispersion method, direct eva- poration condensation method (DECM), submerged-arc nanoparticles synthesis system (SANSS), laser ablation method, and wet chemical method, etc. [2-4,8-12], have been applied to synthesize nanofluids. Dispersion method is a two-step method [13-18], in which commercial nano- particles are dispersed into base fluid under ultrasonic agitation or mechanical stirring. The advantage of this method is that it could prepare nanofluids in a large scale. However, nanoparticle aggregations are difficult to breakup under ultrasonication or stirring. Thus, stability and thermal conductivity of nanofluids prepared with dispersion method are usually not ideal. DECM, SANSS, and laser ablation method are one-step physical methods [19-22], in which metal materials are vaporized by physi- cal technology and cooled into liquids to obtain nano- fluids. These physical methods provide excellent control on the particle size and can produce stable nanofluids.
