Minimization of stock weight during close-die forging of a spindle

In this paper, Finite Element method and full-scale experiments have been used to study a hot forging method for fabri-cation of a spindle using reduced initial stock size. The forging sequence is carried out in two stages. In the first stage, the hot rolled cylindrical billet is pre-formed and pierced in a closed die using a spherical nosed punch to within 20 mm of its base. This process of piercing or impact extrusion leads to high strains within the work piece but requires high press loads. In the second stage, the resulting cylinder is placed in a die with a flange chamber and upset forged to form a flange. The stock mass is optimized for complete die filling. Process parameters such as effective strain distribution, material flow and forging load in different stages of the process are analyzed. It is concluded from the simulations that minor modifications of piercing punch geometry to reduce contact between the punch and emerging vertical walls of the cylinder appreciably reduces the piercing load. In the flange chamber, a die surfaces angle of 52° instead of 45° is pro-posed to ensure effective material flow and exert sufficient tool pressure to achieve complete cavity filling. In order to achieve better compression, it is also proposed to shorten both the length of the inserted punch and the die “tongues” by a few mm.

Classroom of students watching demonstration of closed-circuit TV

Students watch monitors that show a voltage meter being filmed in the Automotive Dept by department head William C. H. Meyer as part of a demonstration of a new technique in closed-circuit television. This is one of a series of photographs accompanying a press release about the development and demonstration of the new technique at the New York Trade School. Original caption reads, "In a classroom on another floor, students all have "front row" seats for the demonstration. Camera concentrates on close-up of a meter, where readings show the result of the voltage-regulator check. Instructor (standing at microphone) is Arthur Richards."

magine if you will the near perfect statefunded program. Yes, I know, such words sound like an oxymoron, given the track record of both state and federally-funded programs, past, present and undoubtedly in the future. Indeed, such words sound almost mythological in light of recent attempts by the federal government to spend us out of the current recession with still doubtful results (so far, a record deficit). Yet, you’re an imaginative individual and can put aside petty political persiflage and visualize such a program. Not only does this program do precisely what it said it would do, it does it so surprisingly well that, as a taxpayer, you’re completely astonished and whole-heartedly impressed.

A general-equilibrium closed-form solution to the welfare costs of inflation (Forthcoming, Revista Brasileira de Economia)

This work presents closed-form solutions to Lucasís (2000) generalequilibrium expression for the welfare costs of ináation, as well as to the di§erence between the general-equlibrium measure and Baileyís (1956) partial-equilibrium measure. In Lucasís original work only numerical solutions are provided.

Avenues to success : electoral strategies and ambition in the Brazilian chamber of deputies

In the second consecutive election for the Brazilian Chamber ofDeputies, the majority of incumbents (75% in 1998 and again 75% in 2002) decided to run for reelection and at least 70% ofthem in both elections were successful, suggesting thus it would be incorrect to ignore static ambition as the main target of Brazilian legislators. It also raises doubts about the assertion that incumbents use their posts to pursue their post-Iegislative careers. However, this number also suggests that not alIlegislators seek reelection, indicating that it is also incorrect to assume alI of them are driven by similar motivations. In their attempts at career survival, incumbents may also run for higher offices (Senator, Governor, Vicegovernor). A minority still, may run for state leveI offices (regressive ambition).Given that static and progressive ambition are the two main types of career choice in Brazil, we focus on the factors that influence the career decision and electoral success of those who choose to run for reelection and those who choose to run for higher-level offices, i.e. senator and governor. We use data recently colIected from the 2002 elections.

Evolution of ethyl carbamate during Madeira wine ageing by GC-MS: a new methodology

Recently, ethyl carbamate (EC) was reclassified by the International Agency for Research on Cancer (IARC) as "probably carcinogenic to humans" and occurs mainly in fermented beverages. Nowadays many countries have set limit values for EC in alcoholic beverages. In this sense and taking into account the low concentrations found in alcoholic beverages, the scientific community has shown interest for the development of new analytical methods, whereby its simplification plays an important role in the EC control and prevention. Firstly, a simple, rapid and sensitive methodology was developed for the EC quantification in fortified wines by microextraction by packed sorbent (MEPS) with gas chromatography coupled with a mass spectrometer detector (GC-MS). This method showed good linearity (R2 = 0.999) and sensitivity (LOD = 1.5 μg/L). The accuracy of the method was assessed by means of repeatability and reproducibility (RSD < 7%). Moreover, a good recovery has been demonstrated (97 – 106%) as well as its applicability (16 fortified wines). Thus, the developed methodology has proven to be an excellent approach for routine quantification of EC in fortified wines. The EC evolution was also evaluated during a year and half of Madeira wine ageing submitted to two traditional ageing methods, estufagem and canteiro, in order to evaluate the formation kinetic. The results revealed that estufagem process increased the formation kinetic and promoted a linear increase of the EC concentration (R2 ≥ 0.977), proportionally to the ageing time (4 months). However, when the wines are firstly submitted to estufagem and then undergo canteiro ageing, the EC values remain almost constant during the following 14 months. The results suggest that estufagem does not seem to be the critical factor in the EC formation, but instead the amount of precursors in the medium.
