BACKGROUND Wedge filters can be used as missing tissue compensators or wedge pairs to alter the shape of isodose curves so that two beams can be angled with a small hinge angle at a target volume without creating a hotspot. AIM In this study the dosimetric properties of Varian Enhanced Dynamic Wedge (EDW) and physical wedges (PW) were analyzed and compared. MATERIALS AND METHODS Ionometric ...

Hub facility location problem looks to find the most appropriate location for deploying such facilities. An important factor in such a problem is the pool of potential locations from which the optimal locations must be selected. The present research was performed to address two key objectives: identifying the factors contributing to the selection locations for hub establishment, and presenting ...

this study aimed to examine the effectiveness of combined microwave-ultrasonic pasteurization system on escherichia coli and vitamin c content in sour cherry juice (scj). based on the findings, microwave output power, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temperature were the most effective factors in reducing e. coli and vitamin c content. in addition,...

China’s grain production has been on a pathway paralleled with urbanization in recent 40 years, from lower efficiency and productivity to the higher ones, met complex impact factors contradiction between sustainable development of farming urbanization. Spatial-temporal pattern China, by total per capita output, was analyzed through Local Moran’I 1985 2019. Until 2019, high-output countries were...

soil compaction and moisture content are two of the factors that greatly influence variations in crop yield. capacitance-based sensor is a sensitive device for estimating soil water content. in this method of soil moisture content measurement, soil acts as the dielectric of the capacitor. throughout this research work, a capacitance-based moisture sensor that can measure the soil moisture conte...
