Bureaucracy and Law a Study of Chinese Criminal Courts and Social Media
BUREAUCRACY AND LAW A STUDY OF CHINESE CRIMINAL COURTS AND SOCIAL MEDIA A dissertation presented by Yu Zhang to The School of Criminology and Criminal Justice In partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Criminology and Criminal Justice Northeastern University Boston, Massachusetts August, 2014 1 BUREAUCRACY AND LAW A STUDY OF CHINESE CRIMINAL COURTS AND SOCIAL MEDIA by Yu Zhang ABSTRACT OF DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Criminology and Justice Policy in the College of Social Sciences and Humanities of Northeastern University August, 2014 2 Abstract Born in a firmly-rooted bureaucratic society, Chinese judiciary has never gained the opportunity to build its own identity. Concurrently, Chinese people, immersed in a bureaucratic culture, always pin their dream of justice on a powerful bureaucracy rather on a weak judiciary. The current study discusses the thousands years of Chinese history and the significant impact of bureaucracy on Chinese society and courts, and then look into the potential change in a global era revolutionized with technology and internet. A story-telling mode is used to analyze eleven important criminal cases to disclose the operations of criminal courts in China. Large amount of social media data are presented to showcase the dynamic legal community and online activism. We do not know exactly the impact of government monitoring of the social media and it is an open question. Chinese online legal activism derives its methods and vitality from multiple and intersecting forces, including the particular internet transmitting formats, actual contemporary protest forms, incipient public space promotion. -
Hydraulic Machinery • Turbine Is a Device That Extracts Energy from a Fluid (Converts the Energy Held by the Fluid to Mechanical Energy)
Hydraulic Machines power point presentation Slides has been adapted from Hydraulic Machines, K. Subramanya 2016-2017 Prepared by Dr. Assim Al-Daraje 1 Chapter (1 Part 1) Prepared by Dr. Assim Al-Daraje INTRODUCTION 2 Hydraulic machinery • Turbine is a device that extracts energy from a fluid (converts the energy held by the fluid to mechanical energy) • Pumps are devices that add energy to the fluid (e.g. pumps, fans, blowers and compressors). 3 INTRODUCTION Fluid-flow machines are very broadly classified as turbo-machines and positive displacement machines. A turbo-machine is a device that adds energy to a fluid or extracts energy from the fluid by virtue of a rotating system of blades. These machines require a rotating element called rotor and relative motion between the fluid and the rotor. 4 If the machine adds energy it is called a pump; if it extracts energy it is called a turbine. The fluid to be pumped can be in incompressible mode throughout its passage in the machine or compressibility effects may come in to picture at different phases of its interaction in the machine. If the fluid is water, the pump device is labeled as water pump. 5 Turbines • J.V. Poncelet first introduced the idea of the development of mechanical energy through hydraulic energy • Modern hydraulic turbines have been developed by L.A. Pelton (impulse), G. Coriolis and J.B.

The Influence of Gear Micropump Body Asymmetry on Stress Distribution
POLISH MARITIME RESEARCH 1 (93) 2017 Vol. 24; pp. 60-65 10.1515/pomr-2017-0007 THE INFLUENCE OF GEAR MICROPUMP BODY ASYMMETRY ON STRESS DISTRIBUTION Wacław Kollek, Prof. Piotr Osiński Urszula Warzyńska Wrocław University of Science and Technology, Poland ABSTRACT The paper presents the results of numerical calculations of stress distributions in the gear micropump body for applications in hydraulic systems, especially in the marine sector. The scope of the study was to determine the most favorable position of bushings and pumping unit in the gear pump body in terms of stress and displacement distribution in the pump housing. Fourteen cases of gear pump bushings and pumping unit locations were analyzed: starting from the symmetrical position relative to the central axis of the pump, up to a position shifted by 2.6 mm towards the suction channel of the pump. The analysis of the obtained calculation results has shown that the most favorable conditions for pump operation are met when the bushings are shifted by 2.2 mm towards the suction channel. In this case the maximal stress was equal to 109 MPa, while the highest displacement was about 15µm. Strength and stiffness criteria in the modernized pump body were satisfied. Keywords: gear micropump, microhydraulics, finite element method 17, 19, 20, 21, 22]. The development of modern gear units is INTRODUCTION associated with the following trends: increasing operating pressure [6, 18], improving total efficiency [4, 10, 15, 18, 23], Gear pumps are the most common group of positive reducing pressure pulsations [3, 18, 25], minimizing weight displacement pumps used in hydrostatic drive systems as [15] and noise [11, 14, 16], and reducing dynamic loads [7, 12, power generators, as well as in lubrication systems in various 13, 19]. -

Originally, the science of hydraulics only covered the physical behavior of water at rest and in motion. The use has broadened its meaning, to include compressed air or gases and oil com- pounds and other confined liquids commonly used under controlled pressure to do some work. Hydraulics can be defined as the engineering science that pertains to liquid pressure and flow. This study includes the manner in which liquids act in tanks, cylinders, hoses, valves and pipes, dealing with their properties and the common ways of utilizing these properties to create motion. It includes the laws of floating bodies and the behavior of fluids under various conditions, and ways of directing this flow to useful ends, as well as many other related subjects and applications. -

WORSTER, RIVERS OF EMPIRE: WATER, ARIDITY AND THE AMERICAN WEST Pantheon Books: New York WATER POWER CORRUPTS ABSOLUTELY Fertile land, freedom from religious oppression and mining opportu- nities fueled by .the idea of manifest destiny initially drew settlers to the Far West.' The storage and distribution of water sustained western set- tlement after the mining booms ended, cattle empires collapsed and the settlers' discovered that eastern cropping and land distribution patterns could not be duplicated in arid or semi-arid regions. Two water uses gave the West a stable population in the late nineteenth-early twentieth cen- turies: (1)an irrigation economy took hold in varying degrees in all states, and (2) western cities grew as relatively affluent Midwesterners arrived and created political pressure to augment limited natural supplies of water.
