  Our study aimed to determine the nutritional, textural and sensorial characteristics of butterfly-shaped rainbow trout which is coated by using enriched chitosan with thyme EO during 15 days ofOur study aimed to determine the nutritional, textural and sensorial characteristics of butterfly-shaped rainbow trout which is coated by using enriched chitosan with thyme EO during 15 days of refrigerated storage (5±1°C). The treatments were Cs (chitosan; 2%, w/v), Cs+T (chitosan; 2%, w/v and Thymus vulgaris EO; 1%, v/v) and C (uncoated control samples). The composition of the EO was investigated by GC/MS. Generally, the EO was found to be rich in the active monoterpene phenols (thymol and carvacrol) and their corresponding monoterpene hydrocarbon precursors such as γ-terpinene and the oxygenated monoterpenes such as linalool. Nineteen constituent out of 116, representing 86.79% of the EO were identified, of which the major ones were thymol (3.63%), carvacrol (21.89%), γ-terpinen (2.05%), and linalool (9.04%). Furthermore, textural and sensorial analyses were performed. Our results demonstrated chitosan coating helped with thyme EO made no unfavorable change in taste. Also it can enhance nutritional, textural and sensorial characteristics of butterfly-shaped rainbow trout during 15 days of refrigerated storage.

Full barrel shifters are often on the critical path, which has led most research to be directed toward speed optimizations. With the advent of quantum computer and reversible logic, design and implementation of all devices in this logic has received more attention. This paper proposes a reversible implementation of a barrel shifter, and also evaluation of its quantum cost is presented.

  In this paper a new moduli set {rⁿ -2,rⁿ -1,rⁿ} is introduced where r = 2k + 1 and k= 1,2,3,... . This moduli set includes pair wise relatively prime moduli, so itIn this paper a new moduli set {rⁿ -2,rⁿ -1,rⁿ} is introduced where r = 2k + 1 and k= 1,2,3,... . This moduli set includes pair wise relatively prime moduli, so it offers the maximum possible dynamic range. For this moduli set, the related circuits are simply realized in the Multiple Valued Logic (MVL) and arithmetic in this moduli set enjoys very high speed operations and simple reverse/forward conversion (RNS to MVL/MVL to RNS). After introducing the new moduli set, we design its related circuits and converters. Finally, we compare the results to those of similar moduli sets and show that our moduli set significantly improves the time complexity while offers greater dynamic range.

  The binary coded decimal (BCD) encoding has always dominated the decimal arithmetic algorithms and their hardware implementation. Due to importance of decimal arithmetic, the decimal format definedThe binary coded decimal (BCD) encoding has always dominated the decimal arithmetic algorithms and their hardware implementation. Due to importance of decimal arithmetic, the decimal format defined in IEEE 754 floating point standard has been revisited. It uses densely packed decimal (DPD) encoding to store significant part of a decimal floating point number. Furthermore in recent years reversible logic has attracted the attention of engineers for designing low power CMOS circuits, as it is not possible to realize quantum computing without reversible logic implementation. This paper derives the reversible implementation of DPD converter to and from conventional BCD format using in IEEE754R.
