?? A steering arm, made from a three piece weldment was creating problems in manufacturing. It was converted to a one piece impression die hot forging at a 13% reduction in weight and reduced manufacturing cost. ?? A cast hub for a large power shovel in a coal field failed, causing an estimated downtime of four to six weeks at a cost of $4000 per hour. The hub was slightly redesigned as an open...

Dental anatomy is the study of morphology of various teeth in human dentitions. The application of dental anatomy in clinical practice is important, and dentist should have a thorough knowledge regarding the morphology of the teeth. At times as a result of genetic variation, environmental factors, diet of an individual and race, variations in the morphology of the teeth can be observed. These v...

Research on the very specific damage to single textile fibres caused by vapour cloud explosions is presented. Vapour cloud explosion experiments were carried out using a selection of 41 garments differing in colour, fibre composition and textile construction. Fibres subjected to a vapour cloud explosion become wider at the end, often taking the form of a ball, bulb or shovel, while the morpholo...

Equipment specifications tend to quote highest achievable performance; but this specification does not tell the whole story of machine behaviour. In the case of shovels, many criteria are used for selecting new equipment, generally related to capital and operating cost, capacity, digging forces, reach, loading rate, and propel rate. Some are competing objectives, such as high loading capacity a...

The present study investigates non-local temporal adjustments before an upcoming length contrast in Italian minimal pairs that differ only in the length of the medial consonant (e.g., geminate word palla "ball" vs singleton word pala "shovel"). This contrast is reportedly signaled by the duration of the singleton/geminate consonant and of the preceding vowel. Here, it is shown that the duration...

The entire length of the beard worm, Oligobrachia mashikoi (Pogonophora), including the posterior end, the "opisthosoma" was collected successfully. This species is exclusive to Tsukumo Bay in Ishikawa Prefecture, Japan. Although the portion preceding the opisthosoma was similar to a fine filament, it abruptly assumed a shape similar to a shovel and appeared to be composed of many segmental str...

The article deals with one of the most important problems mechanization rural and economic work on state irrigation canals ensuring their high-quality functioning. Irrigation canals, water intakes hydraulic structures are destructed deformed from natural climate artificial factors. A large capacity bucket shovel form equipped roller designed for cleaning lined silting sediment was considered. l...
