Abstract Laser ablation of galvanized steel at a wavelength 343, 515 and 1030 nm was compared for single as well multiple picosecond laser pulses. The characteristics ablated craters, such rate, crater shape chemical composition, in relation to the processing parameters were studied. Surface morphology craters characterized with help confocal scanning microscopy electron microscopy. Chemical co...

Some physical properties of pumpkin (Cucurbita pepo L.) and watermelon (Citrullus lanatus L.) seeds were determined at a moisture content of 9.87% and 2.87% (dry basis), respectively. The mean values of length, width, thickness and geometric mean diameter were 19.92, 11.30, 3.22, 9.71 mm for pumpkin seeds, and 13.28, 8.00, 2.64, 6.52 mm for watermelon seeds, respectively. The mean 1000 seed mas...

When the decision was made to euthanatize an acutely laminitic Thoroughbred broodmare, graduate students from the Department of Animal Sciences and Industry reconstructed the skeleton for use as a teaching tool. The reproductive and gastrointestinal tracts were removed and preserved in formalin. The hide, muscle, tendons, ligaments, and organs were removed, and the bones were boiled in water fo...

The unprecedented growth in construction activities have led to speedy consumption of global natural resources like river sand, blue metal, water, and some raw materials like limestone (for producing cement). This study explores the possibility of using Steel-Mesh Reinforced Cementitious Composites (SMRCC) as an alternative to conventional concrete, aiming at sustainability. In order to underst...

The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

We describe a point-of-use (POU) ultraviolet (UV) disinfection technology, the UV Tube, which can be made with locally available resources around the world for under $50 US. Laboratory and field studies were conducted to characterize the UV Tube's performance when treating a flowrate of 5 L/min. Based on biological assays with MS2 coliphage, the UV Tube delivered an average fluence of 900+/-80 ...

This research concerns the design of an agricultural building with a high degree of sustainability, located in a farm in the south of the Tuscany region, Italy. The building, intended mainly as a wine cellar, offers innovative construction solutions of high deconstructability and has features of low environmental impact, economic competitiveness and constructive simplicity. In particular, the d...

rocess and quality control are exP tremely important in achieving optimum production and they have a special place in continuously operating processes. Real-time process monitoring is the comerstone of maintaining an efficient electroplating process. For the steel industry, zinc and nickel electroplating processes used for anticorrosion treatmentl must be monitored to maintain certain standards...

Liquid metal assisted cracking (LMAC) and so-called microcracking are limiting the application of hot-dip galvanized boron steels in direct press hardening process. This study addresses role steel hardenability on behavior ZnFe-coated (galvannealed) 22MnB5 22MnMoB8. Several soaking times forming start temperatures range 800–520 °C examined using a laboratory equipment with hat-profiled tool. Th...
