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.
In this work, metal oxide nanostructures, mainly copper oxide (CuO), nickel oxide (NiO), titanium dioxide (TiO2), and multilayer structure, were synthesized by the DC reactive magnetron sputtering technique. The effect of deposition time on the spectroscopic characteristics, as well as on the nanoparticle size, was determined. A long deposition time allows more metal atoms sputtered from the target to bond to oxygen atoms and form CuO, NiO, or TiO2 molecules deposited as thin films on glass substrates. The structural characteristics of the final samples showed high structural purity as no other compounds than CuO, NiO, and TiO2 were found in the final samples. Also, the prepared multilayer structures did not show new compounds other than th

There is an interesting potential for the use of GFRP-pultruded profiles in hybrid GFRP-concrete structural elements, either for new constructions or for the rehabilitation of existing structures. This paper provides experimental and numerical investigations on the flexural performance of reinforced concrete (RC) specimens composite with encased pultruded GFRP I-sections. Five simply supported composite beams were tested in this experimental program to investigate the static flexural behavior of encased GFRP beams with high-strength concrete. Besides, the effect of using shear studs to improve the composite interaction between the GFRP beam and concrete as well as the effect of web stiffeners of GFRP were explored. Encasing the GFRP

Catalytic reduction is considered an effective approach for the reduction of toxic organic pollutants from the environment, but finding an active catalyst is still a big challenge. Herein, Ag decorated CeO2 catalyst was synthesized through polyol reduction method and applied for catalytic reduction (conversion) of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). The Ag decorated CeO2 catalyst displayed an outstanding reduction activity with 99% conversion of 4-NP in 5 min with a 0.61 min−1 reaction rate (k). A number of structural characterization techniques were executed to investigate the influence of Ag on CeO2 and its effect on the catalytic conversion of 4-NP. The outstanding catalytic performances of the Ag-CeO2 catalyst can be assigne

In this paper, the dynamic behaviour of the stage-structure prey-predator fractional-order derivative system is considered and discussed. In this model, the Crowley–Martin functional response describes the interaction between mature preys with a predator. e existence, uniqueness, non-negativity, and the boundedness of solutions are proved. All possible equilibrium points of this system are investigated. e su‰cient conditions of local stability of equilibrium points for the considered system are determined. Finally, numerical simulation results are carried out to con‹rm the theoretical results.

Double-layer micro-perforated panels (MPPs) have been studied extensively as sound absorption systems to increase the absorption performance of single-layer MPPs. However, existing proposed models indicate that there is still room for improvement regarding the frequency bands of absorption for the double-layer MPP. This study presents a double-layer MPP formed with two single MPPs with inhomogeneous perforation backed by multiple cavities of varying depths. The theoretical formulation is developed using the electrical equivalent circuit method to calculate the absorption coefficient under a normal incident sound. The simulation results show that the proposed model can produce absorption coefficient with wider absorption bandwidth compared w

<span>Distributed denial-of-service (DDoS) attack is bluster to network security that purpose at exhausted the networks with malicious traffic. Although several techniques have been designed for DDoS attack detection, intrusion detection system (IDS) It has a great role in protecting the network system and has the ability to collect and analyze data from various network sources to discover any unauthorized access. The goal of IDS is to detect malicious traffic and defend the system against any fraudulent activity or illegal traffic. Therefore, IDS monitors outgoing and incoming network traffic. This paper contains a based intrusion detection system for DDoS attack, and has the ability to detect the attack intelligently, dynami

A comparative study was done on the adsorption of methyl orange dye (MO) using non-activated and activated corn leaves with hydrochloric acid as an adsorbent material. Scanning electron microscopy (SEM) and Fourier Transform Infrared spectroscopy (FTIR) were utilized to specify the properties of adsorbent material. The effect of several variables (pH, initial dye concentration, temperature, amount of adsorbent and contact time) on the removal efficiency was studied and the results indicated that the adsorption efficiency increases with the increase in the concentration of dye, adsorbent dosage and contact time, while inversely proportional to the increase in pH and temperature for both the treated and untreated corn leav
