STATIC AND DYNAMIC SCANNING

Introduction
An account of the early history of SEM has been presented by McMullan (1988 and 2006) Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner, (Knoll, 1935) it was Manfre[r]

In this chapter, the following content will be discussed: Discuss why it is critical for organizations to be responsive, describe the qualities of an organic organization structure, identify strategies and dynamic organizational concepts that can improve and organization’s responsiveness,...

In this chapter we focus on the dynamic nature of the economy, and the corresponding dynamic characteristics of economic data. We recognize that a change in the level of an explanatory variable may have behavioral implications beyond the time period in which it occurred. The consequences of economic[r]

as a surface acoustic phenomenon with lexical orphonetic hidden dynamics but without any phys-ical constraints in between. This omission leadsto some untenable assumptions. For example,speech is often treated out of convenience as a se-quence of discrete, non-overlapping packets, suchas phonemes, de[r]

This paper focuses on the design a controller for PMSG Wind turbine system bases on dynamic surface control (DSC). DSC is a new technique based on sliding mode control and backstepping which provides the ability to solve problems in backstepping controllers and avoids their drawbacks.

The study of the nature of scalar fields without mass parameter interacting with stiff perfect fluid in Bianchi type space- times is a subject of interest due to its significant role in the description of the universe at the early stages of evolution. Patel [1] obtained the static and non-static pla[r]

This article presents analysis of inverse dynamics of a serial manipulator in milling process. With the exception of positioning accuracy issue, machining by robots have more advantages than by conventional CNC milling machines, due to higher flexible kinematics (many links and degrees of freedom) a[r]

Radiotherapy is an important treatment strategy for head and neck cancers. Tumor hypoxia and repopulation adversely affect the radiotherapy outcome. Accordingly, fractionated radiotherapy with dose escalation or altered fractionation schedule is used to prevent hypoxia and repopulation.

Abstract: SnO2gC3N4 composites as photocatalysts with various weight ratios of SnO2 and gC3N4 were synthesized using a facile method through heating of mixtures of Sn6O4(OH)4 and melamine. The asprepared samples are denoted as MSC1:n where n = 5, 6, 7 corresponding to the weight ratios of Sn6O4(OH)4[r]

In this study, numerical method was used to assess technical properties and improve the Vietnamese tuna purse seine. The data were extracted from the two national level projects. The study results showed that average leadline sinking speed reached 0.139 ms and 0.143 ms and maximum sinking depth was[r]

E-cadherin in colorectal cancer cells may be protective against widespread metastasis.
As Rab11, which functions as a recycling endosome, has been reported to play a role in regulating E-cadherin turn- over in vitro , dysregulation may be associated with cancer formation. Our data subsequently dem[r]

Chapter 5 - measuring results and behavior. In this chapter, the following content will be discussed: Creating competitive advantages. After reading this chapter, you should be able to: the importance of developing forecasts of the business environment; why environmental scanning, environmental moni[r]

Antiangiogenic treatments have been shown to increase blood perfusion and oxygenation in some experimental tumors, and to reduce blood perfusion and induce hypoxia in others. The purpose of this preclinical study was to investigate the potential of dynamic contrast enhanced magnetic resonance imagin[r]

The aim is to increase intracranial control, thereby decreasing symptoms from intracranial progression and a neurological death. There is a rapidly evolving change in the radiation treatment of BMs happening around the world. AWBRT is now being passed over in favour of repeat scanning at regular int[r]

To correlate parameters of Ultrasonography-guided Diffuse optical tomography (US-DOT) with pharmacokinetic features of Dynamic contrast-enhanced (DCE)-MRI and pathologic markers of breast cancer.

In the previous chapter, we looked at UML class diagrams. This chapter continues the study of the static view of software by looking at typical patterns found in class diagrams. These patterns recur in many designs; by learning and using them you are reusing the collective experience of many softwar[r]

the fact that most of the city is at or below sea level, protected only by levees, it has beenestimated that a direct hit by a Category 3 or larger hurricane will “fill the bowl”, submergingmost of the city in 20 feet or more of water (Fischetti 2001). In extreme cases, evacuations areessential to m[r]

A study was conducted on the lingual tonsil of six male crossbred goats of six months of age. The lingual tonsil could not be identified macroscopically but in histological sections aggregations of lymphocytes were seen within the core of vallate papillae present in the root of tongue.

The development of nanotechnology interests the researchers for synthesis of nanoparticles with various bio-applications. The green synthesis of copper nanoparticles using Momordica charantia fruit extract acts as both reducing and capping agent. The biosynthesized CuNps were characterized by using[r]
