background: ethical values offer a framework for behavior assessment, and nursing values influence nurses’ goals, strategies,and actions. a literature review was adopted in order to determine and define ethical values for nurses. materials and methods: this literature review was conducted based on the centre for reviews and dissemination guidelines. the key words used to search relevant sources...

Material resistance is important since different physicochemical properties can be extracted from it. This work describes a novel resistance measurement method valid for a wide range of resistance values up to 100 GΩ at a low powered, small sized, digitally controlled and wireless communicated device. The analog and digital circuits of the design are described, analysing the main error sources ...

This paper presents a finite-element analysis of honeycomb and re-entrant honeycomb structures made of a two-phase composite material which is optimized with respect to selected parameters. It is shown that some distributions of each phase in the composite material result in the counter-intuitive mechanical behaviour of the structures. In particular, negative values of effective Poisson's ratio...

CNC turning is widely used as a manufacturing process through which unwanted material is removed to get the high degree of surface rough. In this research article, Taguchi technique was coupled with grey relation analysis (GRA) to optimize the turning parameters for simultaneous improvement of productivity, average surface roughness (Ra), and root mean square roughness (Rq).Taguchi technique L2...

Human hair powder reference material was prepared and certified for elemental composition. Human scalp hair (from Japanese men) was washed in a non-ionic detergent solution in an ultrasonic cleaner, dried, ground in an agate ball mill, sieved through a polyethylene net, blended, bottled (1100 vials, 2 g each), and finally sterilized by 60Co radiation. The prepared material satisfied the homogen...

free vibration of simply supported circular cylindrical shell made of functionally graded material (fgm) under internal pressure was investigated. the effective material properties are assumed to vary continuously along the thickness direction according to a volume fraction power law distribution. first order shear deformation theory based on love's first approximation theory was utilized in th...

The all nearest smaller values problem is deened as follows. Let A = (a 1 ; a 2 ; : : :; a n) be n elements drawn from a totally ordered domain. For each a i , 1 i n, nd the two nearest elements in A that are smaller than a i (if such exist): the left nearest smaller element a j (with j < i) and the right nearest smaller element a k (with k > i). We give an O(loglog n) time optimal parallel alg...

The recognition of high risk groups in the setting of occupational standards in the United States really appears to date from the establishment of OSHA of 1970 and the concomitant mandate for the development of criteria for Federal occupational exposure standards. Although the ACGIH recommended threshold limit values (TLV's) had been available as guidelines in increasing numbers since shortly a...

As worldwide demand of hydrocarbon is growing fast, the oil and gas companies have been forced to explore reservoirs with more hostile conditions, such as high-pressure, high-temperature conditions. Improved technology, material selection and testing procedures are required to overcome the common problems in these conditions. One of the main phases of well construction is cementing job. Appropr...
