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.
The widespread use of the Internet of things (IoT) in different aspects of an individual’s life like banking, wireless intelligent devices and smartphones has led to new security and performance challenges under restricted resources. The Elliptic Curve Digital Signature Algorithm (ECDSA) is the most suitable choice for the environments due to the smaller size of the encryption key and changeable security related parameters. However, major performance metrics such as area, power, latency and throughput are still customisable and based on the design requirements of the device.
The present paper puts forward an enhancement for the throughput performance metric by p

Aromatic Schiff-bases are known to have antibacterial activity, but most of these compounds are sparingly soluble in water. The present work describes the synthesis of new Schiff-bases derived from branched aminosugars. Treatment of 3-Amino-3-Cyano-3-Deoxy-1,2:5,6-Di-O-Isopropylene-α-D-Allofuranose (1) with the aldehydes (2) under reflux in methanol afforded the Schiff-bases (3) in good yields. The new Schiff-bases were in accord with their NMR, IR spectral data and elemental analysis.
novel spectrofluorimetric flow injection analysis (FIA) method was developed for the selective quantification of ascorbic acid via fluorescence quenching of serotonin hydrochloride. The system employs a custom-designed photometric array comprising 16 irradiation sources arranged in a dual-axis matrix—eight aligned horizontally and eight orthogonally, enabling multi-angle excitation and enhanced spectral resolution. Fluorescence signals were captured using a twin-pair solar cell detector, offering high sensitivity and minimal optical interference. The method exhibited a linear calibration range of 0.1–30 limit of detection (LOD) of 0.025 μ μ g/mL with a correlation coefficient (r mol /L, equivalent to 4.403 * 10 4 μ 2 ) of 0.9966, a g

Methicillin resistant Staphylococcus aureus (MRSA) is one of the principal nosocomial causative agents. This bacterium has the capability to resist wide range of antibiotics and it is responsible for many diseases like skin, nose and wounds infection. In this study, randomly amplified polymorphic DNA (RAPD)-PCR was applied with ten random primers to examine the molecular diversity among methicillin resistant Staphylococcus aureus (MRSA) isolates in the hospitals and to investigate the genetic distance between them. 90 Isolates were collected from clinical specimens from Iraqi hospitals for a total of 90 isolates. Only 10 strains (11.11%) were found to be MRSA. From these 10 primers, only 9 gave clear amplification products. 91 fragment l

This paper presents a computer simulation model of a thermally activated roof (TAR) to cool a room using cool water from a wet cooling tower. Modeling was achieved using a simplified 1-D resistance-capacitance thermal network (RC model) for an infinite slab. Heat transfer from the cooling pipe network was treated as 2-D heat flow. Only a limited number of nodes were required to obtain reliable results. The use of 6th order RC-thermal model produced a set of ordinary differential equations that were solved using MATLAB - R2012a. The computer program was written to cover all possible initial conditions, material properties, TAR system geometry and hourly solar radiation. The cool water supply was considered time
