Acetamide (CH3CONH2) has been detected in emission and absorption toward the star-forming region Sagittarius B2(N) with the 100 m Green Bank Telescope (GBT) by means of four A-species and four E-species rotational transitions. All transitions have energy levels less than 10 K. The Sgr B2(N) cloud is known to have a cold halo with clumps of gas at several different velocities. Absorption feature...

Sheet metal forming is one of the most popular technologies for obtaining finished products in automotive industries. The main techniques sheet forming: microforming, warm/hot forming, incremental flexible-die Electromagnetic Electrohydraulic Spinning and Shear Spinning, Flow Forming cold forming. One stamping process. In production line Ravne VPS400 1992, we take twenty details looking quality...

Using DIRBE and FIRAS maps at high latitude (|b| > 10) we derive the spatial distribution of the dust temperature associated with the diffuse cirrus and the dense molecular clouds. For a ν emissivity law, we find that the equilibrium dust temperature of the cirrus is about 17.5 K with only small variations over the high latitude sky. Comparison of the far Infrared DIRBE maps shows the presence ...

Metal sheet anisotropy is the directional dependence of mechanical properties. It key factor that must be considered when using numerical simulation to predict any manufacturing process involves plastic deformation. The strain ratio, also known as Lankford coefficients or R values, together with forming limit curves (FLC), are industry standards for assessing formability metals. Complete experi...

in this study, accumulation of h2o2, malondialdehyde (mda) (as cold-induced oxidative stress indicators), the transcript levels of dehydrin and beta-glucosidase genes (involved in metabolic responses) was evaluated in chickpea cv. jam, using qrt-pcr during control, cold acclimation (ca), cold stress (cs), recovery, and freezing phases. results showed the existence of wide range of genetic capac...

Electromagnetic forming (EM forming or magneforming) is a type of high velocity, cold forming process for electrically conductive metals, most commonly copper and aluminum. The work piece is reshaped by high intensity pulsed magnetic fields that induce a current in the work piece and a corresponding repulsive magnetic field, rapidly repelling portions of the work piece. The work piece can be re...
