Abstract:
Different types of radiations have been found to be widely applicable in modifying the properties of materials. In this work colour strength (K/S) and colour fastness of reactive dyed cotton fabric has been studied with the application of three radiations; microwave, ultraviolet and ultrasonic. Analysis of variance and comparison of mean values statistical tests were carried out to find out the effect of different radiation treatment time and fabric density on colour strength of cotton fabrics. The colour strength (K/S) of dyed fabric enhanced significantly by pretreatment with different radia

Abstract:
Theoretical methods of classical mathematical physics investigate the acoustic and electromagnetic radiation generated by capillary oscillations of a charged drop of an ideal uncompressible electroconductive fluid in an ideal nonconductive medium. The radiations discussed are found in first-order analytical asymptotic calculations of smallness by the dimensionless amplitude of droplet oscillations. Analytical expressions were found for the intensity of acoustic and electromagnetic radiation, which differ by several orders of magnitude and fall on different frequency bands. Acoustic radiation f

The fuel element plates of research reactors are subjected to swelling phenomena. These structure modifications impact an initial inter-plate distance of 1.8 mm. An ultrasonic device has been developed to investigate this parameter. With a 1 mm thickness, it relies on two transducers linked to an electronic system. The feasibility of the distance measurement has been proved in a previous study and the irradiation impact on the transducer components is here studied. To do so, a radiation resistance experiment was realized in the Arc-Nucleart Institute of Grenoble. It allowed the study of the in

A convenient approach for the synthesis of β-cyanoepoxides is illustrated by iodine(III)-catalyzed epoxidation of electron-deficient β-cyanostyrenes, wherein the active catalytic iodine(III) species was generated in situ. The epoxidation of β-cyanostyrenes was performed using 10 mol% PhI as precatalyst in the presence of 2.0 equivalents Oxone as an oxidant and 2.4 equivalents of TFA as an additive at room temperature under ultrasonic radiations. The β-cyanoepoxides were isolated in good to excellent yields in a short reaction time.

Abstract:
Second generation bioethanol production technology relies on lignocellulosic biomass composed of hemicelluloses, celluloses, and lignin components. Cellulose and hemicellulose are sources of fermentable sugars. But the structural characteristics of lignocelluloses pose hindrance to the conversion of these sugar polysaccharides into ethanol. The process of ethanol production, therefore, involves an expensive and energy intensive step of pretreatment, which reduces the recalcitrance of lignocellulose and makes feedstock more susceptible to saccharification.

The principle of operation of a novel rotating disk ultrasonic intensity meter is studied. Its characteristics are explained by a competition between acoustic radiation pressure and viscous drag on the disk. Acoustic streaming does not play a significant role in the operation of this meter as it is now configured. Experiments are described which were done to find the optimum dimensions and position for a nylon disk. In this optimum configuration, the rotation rate of the disk is related to the ultrasonic intensity by a power law. This relationship is theoretically predicted and found to hold

During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g., for positioning, sorting, and aggregation. However, when manipulating cells using ultrasound, especially using high acoustic amplitudes, a great deal of heat can be generated.

Abstract:
It is proposed to carry out the spatial effect of high-energy ultrasound dynamic effects with controlled characteristics on the solid phase particles of the ore pulp in the deslimer input product to increase the efficiency of thickening and desliming processes of iron ore beneficiation products. The above allows predicting the characteristics of particle gravitational sedimentation based on an assessment of the spatial dynamics of pulp solid- phase particles under the controlled action of high-energy ultrasound and fuzzy logical inference. The object of study is the assessment of the character

Abstract:
The inspection of welds made onto in-service pipelines, which are made primarily for attaching branch connections and repair sleeves, has been the subject of much concern in recent years. The difficulties associated with the inspection of these welds have long been recognized and, historically, the amount of inspection given to such welds has been small. The inspection of welds joining various appurtenances to pipelines is hampered for a number of reasons. The joint geometries can vary considerably, but none of them are particularly suited to detailed inspection. Surface techniques, such as ma

Abstract:
This project has taken a newly developed ultrasonic examination technique that is capable of detecting, characterizing, and sizing flaws with fewer errors and less time than ever before and applying the automated data recording and imaging technologies for a more economical and more desirable pipeline ultrasonic examination process. FAST TM (Flaw Analysis and Sizing Technique) is a conceptually simple but extremely innovative and highly effective ultrasonic weld examination technique. The development of this technique was accomplished to reduce weld examination time while improving examination
