Techniques for measuring upper femoral torsion in children have been progressively developed by Dunn (1952), Ryder and Crane (1953), Dunlap, Shands, Hollister, Gaul and Streit (1953), Magilligan (1956) and Shands and Steele (1958). The projected neck-shaft angle of inclination and the projected angle of femoral torsion (Fig. 1) may be used to plot the true torsion on a table based on a mathemat...
8 The annual Sandhill crane (Grus canadensis) migration through Nebraska, which is 9 thought to be a major source of fecal pollution to the central Platte River, is of unknown 10 human health risk. To better understand potential risks, the presence of Campylobacter 11 species and three fecal indicator bacterial groups (Enterococcus spp., Escherichia coli 12 and Bacteroidetes) were assayed by PC...
The risk to human health of the annual sandhill crane (Grus canadensis) migration through Nebraska, which is thought to be a major source of fecal pollution of the central Platte River, is unknown. To better understand potential risks, the presence of Campylobacter species and three fecal indicator bacterial groups (Enterococcus spp., Escherichia coli, and Bacteroidetes) was assayed by PCR from...
This paper demonstrates the method of controlling the crane using Dual Tone Multi Frequency (DTMF) technology. The crane is controlled by a mobile phone that makes a call to another mobile phone attached to the crane's control panel. During the call, if any button is pressed, tone corresponding to that button is heard at the other end of the call. This tone is received
A comparative approach was used to evaluate the cryosurvival of turkey and crane sperm frozen in a dimethylacetamide (DMA) cryodiluent supplemented with osmoprotectants and ATP. A range (6-26%) of DMA concentrations was used alone or in combination with ATP (30, 60 or 118mM) or one of the following osmoprotectants: (1) sucrose (turkey, 8.0%; crane, 5.0%); (2) 5.0% sucrose and 5.0% trehalose; or...
At present, about 160,000 and 100,000 cranes are migrating on the West-European and on the Baltic-Hungarian routes, respectively, from the northern, middle, and northeastern parts of Europe. On both routes, the resting maxima, simultaneously determined since the 1980’s, has increased three-fold. This increase in migratory cranes is the result of shorter migration routes with higher return rates...
Introduction: Human error plays a significant role in the occurrence of industrial accidents. Displacement and unloading operations are operations in which the occurrence of human error may lead to plenty of human and financial losses. The present study aimed to investigate the possibility of human error occurrence in overhead crane operators in a Steel Company in Hormozgan, Iran. Material & Me...
Engineering fatigue fracture failure is one of the most common phenomena of mechanical and structural failure, statistically representing approximately 50 to 90% of total mechanical damage [1]. Lattice structures have been widely used in crane booms, steel plants, parking garages, offshore platforms and other fields [2] to [4]. In a crane, the lattice boom has better mechanical properties compa...
