Abstract The Knights of Labor, the first national industrial union in the United States, was founded in Philadelphia on December 9, 1869, by Uriah Stephens (1821-82) and eight other Philadelphia garment cutters. Intended to overcome the limitations of craft unions, the organization was designed to include all those who toiled with their hands. By mid-1886 nearly one million laborers called themselves Knights, making the organization the largest and most influential labor union in nineteenth century America. Stephens aspired to unite all wage-earners into a single organization regardless of skill, race, or sex. The organization excluded liquor dealers, lawyers, bankers, and professional gamblers. Stephens stressed the importance of solidarity within the ranks of labor in order to meet the power of capital. Between December 1869 and April 1875 the Knights made few gains outside of the city. During that time eighty-five local assemblies were established, seventy within the Philadelphia region. After the Great Railroad Strike of 1877 membership expanded and the first national officers were initiated after a convention in Reading, Pa., in 1878. In 1879 Terence V. Powderly (1849-1924), a native of Carbondale, Pa., replaced Stephens as Grand Master Workman after Stephens resigned the position. Powderly, who also served as the socialist mayor of Scranton from 1878-84, led the Knights until 1893. This study includes an introduction, four chapters and a conclusion, chapter I dealing with The roots of the labor movement in the United States of America until 1866 , This chapter dealt with a number of topics which are as follows: the first topic the labor movement in the colonial era, the second topic the factors crystallization of the labor movement after independence 1783-1840, and the third topic union activity until the end of the American Civil War 1840-1865. As for the second chapter, which was titled: The Emergence of the Workers' Organization and its Role in the Workers' Movement until 1881, it dealt with a number of topics which are as follows: The first topic is the general scene of the labor movement before the formation of the Workers' Organization 1866-1869, and the second topic is the principles and structure of the Workership Organization, the topic The third activity and work position of the Knights of the Economic Crisis 1870-1879, the fourth topic, Terence V. Powderly and his role in the development of the organization 1879-1881. The third chapter came under the title: The Rise and Prosperity of the Workers ’Organization 1881-1886, which dealt with a number of topics, as follows: The first topic: The factors of the rise of the Workers’ Organization, the second topic: the organization’s position on black workers, the third topic the organization’s activity in the southern states, the fourth topic position The organization from the strike of 1885-1886 and its reflection on the increase in membership, Section Five the organization's position on political action. Finally, the fourth chapter came under the title, Factors of Weakness of the Labor Knights Organization and its Decline 1886-1895. A number of topics were discussed as follows: The first topic: Organizational and structural problems within the Labor Knights Organization, the second topic is the repercussions of the failure of strikes on the organization in 1886-1887, the third topic is the position of the Knights on the Haymarket case And its negative repercussions, the fourth topic: internal differences and divisions and its role in the weakness of the organization, the fifth topic: the end of the Terence V. Powderly era and the decline of the organization's role in the labor movement.

Composite materials are widely used in the engineered assets as aerospace structures, marine and air navigation owing to their high strength/weight ratios. Detection and identification of damage in the composite structures are considered as an important part of monitoring and repairing of structural systems during the service to avoid instantaneous failure. Effective cost and reliability are essential during the process of detecting. The Lamb wave method is an effective and sensitive technique to tiny damage and can be applied for structural health monitoring using low energy sensors; it can provide good information about the condition of the structure during its operation by analyzing the propagation of the wave in the

In this paper, split-plate airlift electrochemical reactor as an apparatus with new configuration for wastewater treatment was provided. Two aluminum plates were fixed inside the reactor and present two functions; first it works as split plates for internal loop generation of the airlift system (the zone between the two plates acts as riser while the other two zones act as downcomer) and second it works as two electrodes for electrocoagulation process. Simulated wastewater contaminated with zinc ions was used to test the performance of this apparatus for zinc removal by studying the effect of different experimental variables such as initial concentration of zinc (50-800 ppm), electrical current density (2.67-21.4 mA/cm2), init

Four isoenzymesI,II,III,IV have shown an optimum pH at 7.4.The four isoenzymes obeyed Arrhenius equation up to 37º C and their Ea and Q10 constants were determined .
Shear and compressional wave velocities, coupled with other petrophysical data, are vital in determining the dynamic modules magnitude in geomechanical studies and hydrocarbon reservoir characterization. But, due to field practices and high running cost, shear wave velocity may not available in all wells. In this paper, a statistical multivariate regression method is presented to predict the shear wave velocity for Khasib formation - Amara oil fields located in South- East of Iraq using well log compressional wave velocity, neutron porosity and density. The accuracy of the proposed correlation have been compared to other correlations. The results show that, the presented model provides accurate

Experiments research is done to determine how saturated stiff clayey soil responds to a single impulsive load. Models made of saturated, stiff clay were investigated. To supply the single pulse energy, various falling weights from various heights were tested using the falling weight deflectometer (FWD). Dynamic effects can range from the major failure of a sensitive sensor or system to the apparent destruction of structures. This study examines the response of saturated stiff clay soil to a single impulsive load (vertical displacement at the soil surface below and beside the bearing plates). Such reactions consist of displacements, velocities, and accelerations caused by the impact occurring at the surface depth induced by the impact loads

This study offers numerical simulation results using the ABAQUS/CAE version 2019 finite element computer application to examine the performance, and residual strength of eight recycle aggregate RC one-way slabs. Six strengthened by NSM CFRP plates were presented to study the impact of several parameters on their structural behavior. The experimental results of four selected slabs under monotonic load, plus one slab under repeated load, were validated numerically. Then the numerical analysis was extended to different parameters investigation, such as the impact of added CFRP length on ultimate load capacity and load-deflection response and the impact of concrete compressive strength value on the structural performance of

This study presents, for the first time, an innovative Jet Plasma-assisted technique for the green synthesis of TiO₂@Ag core–shell nanoparticles using chard leaf extract as a natural reducing and stabilizing agent. The Jet Plasma provides a highly energetic environment that accelerates nucleation and core–shell formation at low temperatures without toxic precursors. The synthesized nanoparticles exhibited uniform and stable structures, as confirmed by comprehensive characterization techniques including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible (UV–Vis) spectroscopy, transmission electron microscopy (TEM), and zeta potential analysis. XRD patterns confirmed the crystalline anatase
