a method based on the ultrasound-assisted solidification of floating drop microextraction technique was developed for the spectrophotometric and spectrofluorimetric determination of curcumin in turmeric powder. in this work a small volume of an organic solvent was floated on the surface of an aqueous solution. after sonication the organic solvent is solidified and separated. the effect of extra...

Floating matrix tablets are designed to prolong the gastric residence time after oral administration, at a particular site and controlling the release of drug especially useful for achieving controlled plasma level as well as improving bioavailability. With this objective, floating dosage form containing clarithromycin as drug was designed for the treatment of Helicobacter pylori. Tablets conta...

Commercial applications and databases typically store numerical data in decimal format. Currently, however, microprocessors do not provide instructions or hardware support for decimal floating-point arithmetic [ 1 ]. Consequently, decimal numbers are often read into computers, converted to binary numbers, and then processed using binary floating-point arithmetic. Results are then converted back...

Floating roofs are widely used to store petroleum products with high volatility. This is to prevent the product loss and to ensure safe environment around the storage tanks. However, small number of researches were accomplished. These researches aim at study the design of the floating roof and the associated risks that it faces during operation. In an effort to compensate the lack of knowledge ...

Floating-point processing utilizes a format defined in IEEE 754, and is supported by microprocessor architectures. However, the IEEE 754 format is inefficient to implement in hardware, and floating-point processing is not supported in VHDL or Verilog. Newer versions, such as SystemVerilog, allow floating-point variables, but industry-standard synthesis tools do not support floating-point techno...

the objective of this work was to develop and evaluate the levofloxacin hemihydrate floating formulations (f1-f9). selection of optimized batch was done by model dependent approach and novel mathematical approach. f1-f9 batches were prepared by direct compression method using gelucire 43/01 (hydrophobic) and hydroxypropylmethylcellulose (hydrophilic) polymer in different ratios. the floating ta...

The surgical rehabilitation of mixed hearing losses can be performed by coupling the floating mass transducer of the Vibrant Soundbridge to the round window. The quality of coupling the floating mass transducer to the round window is crucial for the audiological outcome. It was the aim of this study to further observe the different patterns of floating mass transducer position at the round wind...

This paper examines the implementation of floating-point operations in the IA-64 architecture from the perspective of the IEEE Standard for Binary Floating-Point Arithmetic [1]. The floating-point data formats, operations, and special values are compared with the mandatory or recommended ones from the IEEE Standard, showing the potential gains in performance that result from specific choices. T...

purpose: to report a case of free floating pyogenic granuloma within the lacrimal sac. case report: a 13 month old infant with unresolving dacryocystitis and history of two times failed probing and once failed turbinate fracture was scheduled for dacryocystorhinostomy (dcr). a free floating red mass was removed from the sac. histopathologic examination confirmed a diagnosis of pyogenic granulom...

BMDs, HDDs, and K*BMDs provide compact representations for functions which map Boolean vectors into integer values, but not floating point values. In this paper, we propose a new data structure, called Multiplicative Power Binary Hybrid Diagrams (*PBHDs), to provide a compact representation for functions that map Boolean vectors into integer or floating point values. The size of the graph to re...
