early bronze age (eba) in the middle east is considered to be the dawn of civilization, spread of writing, and proto-urbanism; and mesopotamia was the center of these historical events. cultural material remains at the beginning of this period in this vast area – including western iran, caucasus (also beyond), anatolia, levant and northern mesopotamia – have wonderful similarities in spite of d...

The presence of valves in the head and neck veins is known since classical anatomical dissections. Previous studies have investigated whether jugular veins show constant valves at their ostium and whether these valves are physiologically competent, but, unluckily, these studies have reported conflicting results. Further, recent observations have raised the question whether the incompetence of j...

With the development in field of research and academics, publishing has become one most important aspect for further technological sciences. The authors must always take care their writings publications. Publications draw inferences from data which can be manipulative or fabrication leads to detrimental researchers. Good papers encourage new Unluckily, these days led unethical practices This pa...

When wireless senor networks (WSNs) are deployed in hostile areas, they indeed need to be secured by security mechanisms. To do this, cryptographic keys must be agreed on by communicating nodes. Unluckily, due to resource constraints, the key agreement problem in wireless sensor networks becomes quite intricate. In this paper, we propose a new ID-based random key pre-distribution scheme that is...

Abstract The Abbé error is a key factor for high-precision CNC machine tools. Unluckily, it not taken into account in traditional tool volumetric models. In this respect, based on the models, new model containing performed by analyzing mechanism of formation and 21-item geometric measurement data, arm, angle functional relationship. Moreover, integrated qualitative quantitative simulation metho...
