This paper reports on an attempt to modify a circular knitting machine such that it would operate without the need for a customary tension system where a kinitting machine can operate without an asymmetric take-down system preliminary results appear promising and warrant further development. 

background: today, despite the many advances in early detection of diseases, cancer patients have a poor prognosis and the survival rates in them are low. recently, microarray technologies have been used for gathering thousands data about the gene expression level of cancer cells. these types of data are the main indicators in survival prediction of cancer. this study highlights the improvement...

regarding the importance sizing and grading crop in the market and other processing operations, in this study, a machine for hazelnut sizing designed, constructed and evaluated. the machine based on sizing mechanism of diverged belt. the sizing unit has a structure similar to a horizontal belt conveyor. the distance between the ropes at the entrance of the product (the end of the driven roller)...

Selecting an appropriate manufacturing machine is a very important and complex problem for firms, which usually have to deal with both qualitative and quantitative criteria. Taking into account the differences among machines in terms of cost, speed, quality and after sale services, type and number of machines are important parameters to consider. Therefore, the goal of thi...

klinkenberg permeability is an important parameter in tight gas reservoirs. there are conventional methods for determining it, but these methods depend on core permeability. cores are few in number, but well logs are usually accessible for all wells and provide continuous information. in this regard, regression methods have been used to achieve reliable relations between log readings and klinke...

organic manure plays an important role in the improvement of soil structure by decreasing bulk density and increasing porosity. however, the method of manure spreading influences its beneficial impact on soil structure. in this study, a novel helical manure distributor machine capable of spreading manure with different moisture contents at maximum distribution width was developed and the machin...
