in order to evaluate the effect of different sources and rates of nitrogen the growth and biomass production of purslane, a randomized complete block design was conducted with three replications at the agricultural research farm of shahrekord university in 2012. fertilization treatments were consisted of control (no n amendment), 30 and 90 kg n ha-1in the form of urea fertilizer, 30 and 90 kg n...

The article considers the technological process of production cutting department a sewing enterprise and typical equipment used during such process. It is revealed that increase in range products, appearance new materials, speed changing models, methods processing, etc., necessitates systematic search for rational effective solutions production, including through introduction modern innovative ...

Abstract This paper proposes a manufacturing technology plan based on the combination of 3D printing and precision cutting for certain projectile fairing part with thin-walled cavity structure. By holistically taking into account process design requirements, one hand, structure required is incorporated original to improve manufacturability parts; other comprehensive research plan, processing st...

Many reasons exist for companies to use quasicontinuous wave (QCW) fi ber lasers, including the fact that a fi ber laser combines the drilling and welding advantages of a pulsed Nd:YAG laser with the cutting capabilities of a CO2 laser. This combination of processing performance is not possible with the older technology, so in the past many companies owned both CO2 and Nd:YAG lasers to handle a...

After-sales services are important to manufacturing companies both as a source of income and as a source of gaining competitive advantage. Searching for new sources of value in the after-sale market is thus of importance for these companies since it could help them to attract customers. Manufacturing companies are now seeking innovative ways to develop after-sales services with the use of remot...

Electrosurgery uses electricity to remove tissue, coagulate bleeding, or destroy tumors. Modern units, first developed for application in neurosurgery, are now available in office models that are most commonly used by the family physician for cutaneous surgery. Electrosurgery can accomplish cutting, coagulation, desiccation, and fulguration. Electrosurgical equipment for the office is relativel...

In 2005 Schneider Electric's Innovation Department began running tests to assess the performance of ZigBee, a ready-to-use wireless technology with ultra-low power consumption. The department's aim was to gauge ZigBee's performance in helping to ensure the continuous operation of machines and processes, even in harsh industrial conditions, while contributing to a greener environment. The cost-r...

Estimation and modeling of soft tissue deformation during cutting is important for developing a reality based haptic interaction model for surgical training and simulation. In this paper, we are interested in understanding the effect of parameter changes, such as the cutting speed and the angle of cutting, to develop a predictive model that is self consistent with the experimental observations....

We present the use of an accessible micromachining technique (acoustic micromachining) for manufacturing micron-feature surfaces with non-discretely varying depth. Acoustic micromachining allows for non-photolithographic production of metal templates with programmable spatial patterns and involves the use of standard acoustic, cutting and electroplating equipment for mass production of vinyl re...

Pulmonary overinflation syndrome (POIS) is a group of barotrauma-related diseases caused by the expansion of gas trapped in the lung, or over-pressurization of the lung with subsequent over-expansion and rupture of the alveolar air sacs. This group of disorders includes arterial gas embolism, tension pneumothorax, mediastinal emphysema, subcutaneous emphysema and rarely pneumopericardium. In th...
