There were a number of aircraft and engine manufacturers active in Germany in 1930s and 1940s. Some were quite well known, e.g., Messerschmitt (former Bayerische Flugzeugwerke), Focke-Wulf, Junkers, Dornier, etc. Some others were rather obscure, e.g., Hamburger Flugzeugbau, Klemmflugzeugbau, etc. The Reichsluftfahrtministerium (RLM) had a rather convoluted designation system (they thought that it was an improvement over the older one, of course) to provide a (supposedly) simple and unambiguous identification of every German civilian and military aircraft and its corresponding airframe design. Manufacturers were represented by two letters: the first letter in upper case, the second usually in lower case. A selection of the most famous ones is listed in Table 12-1. It should be noted that a mass-production model by a certain manufacturer, say, Messerschmitt Bf 109, were manufactured in the factories of other manufacturers (e.g., Fieseler or Gotha) under license. This system was under the control of the RLM (later in the war, starting in early 1944, under the supervision of the Armament Ministry – see below).

Milling Machine And Cleaning Egg Cleaning Reballs Automatically Completed With The Screw Conveyor System And Auto Washer is made with the aim of increasing productivity and the effectiveness of the production of SME quail egg satay in Surabaya. Egg peeler This semi automatic quail is designed as simply as possible to make it easier mass production and easy maintenance. This machine is added screw conveyor system which is covered with sponge and machine walls, there is a polisher made from stainless which serves as a boiled egg quail peeler. The addition of an auto water washer on this machine uses a hose connected with a water tap to be able to clean automatically when the engine have started working on peeling boiled eggs. Material in direct contact with eggs using stainless steel type 430 SS foodgrade with 3mm thick to maintain the level of hygiene of the production process. Then the system the drive on this machine uses a DC electric motor with a power of ½ PK which transmitted by pulleys and V-belts to reduce input power to more smooth round. Selection of the ½ PK motor is intended for rotation in this engine can be smoother and softer, not too fast so the egg doesn't break. Dimension machine made measuring 110 cm x 65 cm x 52 cm with stripping capacity 1200 quail eggs / hour. Features that have this machine can improve the productivity process of SME quail eggs is threefold, so that the problem of SMEs is quail egg satay for stripping and cleaning the eggs takes a long time to complete.

Beekeepers are faced with quite a number of challenges such as selection of fields and enhancement of honey production. In this paper crisp deterministic honey bee production model was formulated in an attempt to optimize the distribution of beehives in the apiary in order to maximize production of honey and minimize unhealthy competition among foraging bees which often arises as a result of overcrowding. The model was characterized using Weighted sum model (WSM) and Analytic Hierarchical Model (AHM). Finally the validity of the model was tested with the real life data and the results obtained shows that proper distribution of the bee hives in the apiary is important to maximize production and minimize unpleasant fields.

At present, several programs for mass production of MOX bulk are on going. The MOX bulk is the capacity of the container to be used to generate MOX fuel. One of them is the selection of the vessel configuration for efficient evaporation of large amount of solution. Two types of vessel as shallow and cylindrical, are under examinations. The shallow vessel has been successfully cleared examinations in moderate running with no flushing, but the amount of products per batch is rather small. On the other hand, the cylindrical vessel is newly proposed with the intent of increasing the production capacity per batch, but has flushing the solution from the top of the vessel by the Microwave Heating (MH). Elucidation on the mechanism of dynamic behavior of the flushing and spilling is our purpose of study. It was carried out by designing a equipment which imitated the practical setup for microwave heating. A visual observation was conducted to clarify the mechanism of dynamic behavior on the sudden nucleation of the solution in the deep cylindrical vessel under MH. The experiment was continued by changing the height and the shape in order to perform the effect evaluation of the size and the shape of vessel.

While the research on pretask planning has concentrated on its effects on learners’ task performance in terms of fluency, accuracy, and complexity, its possible influence on the overall discourse level, such as discourse management and coherence, has been largely ignored. The present study addresses the inadequacy by uncovering the potential effects of pretask planning on Chinese EFL (English as a foreign language) learners’ selection of referential expressions in oral narratives. Fifty-six intermediate-level learners were tasked with retelling the story of Modern Times under one of two conditions, that is, either with 10-minutes strategic planning or without any planning time. An additional 25 native speakers (NSs) also narrated the same story under the same task conditions. Their narratives were audio recorded, transcribed, and coded based on a coding scheme that distinguished the roles of characters, types of reference, and discursive status of reference. A combination of statistical analysis and discourse analysis showed that (1) compared with NSs, the EFL learners were overexplicit in using noun phrases and proper names to refer to singular characters, but not so in joint reference to the major characters; and (2) pretask planning facilitated more target-like selection of referential expressions when major characters were referred to, although it did not bring the learners’ performance up to NS standards. However, the impact of planning time on referential use seemed to be moderated by the role prominence. These findings were explained within the framework of Levelt’s speech production model and Skehan’s Limited Attentional Capacity Hypothesis.

In recent years, the effective purification of PEGylated therapeutic proteins from reaction media has received particular attention. Although several techniques have been used, affinity-based strategies have been scarcely explored despite the fact that, after PEGylation, marked changes in the molecular affinity parameters of the modified molecules are observed. With this in mind, future contributions in the bioseparation of these polymer-protein conjugates are expected to exploit affinity in chromatographic and nonchromatographic techniques which will surely derive in the integration of different operations. However, this will only occur as novel ligands which are simultaneously found. As it will be mentioned, these novel ligands may be screened or designed. In both cases, computer-aided tools will support their identification or development. Additionally, ligand discovery by high-throughput screening (HTS) is believed to become a fast, economic, and informative technology that will aid in the mass production of ligands along with genetic engineering and related technologies. Therefore, besides analyzing the state of the art in affinity separation strategies for PEGylated molecules, this review proposes a basic guideline for the selection of adequate ligands to provide information and prospective on the future of affinity operations in solving this particular bioengineering problem.
