Brown Bess Musket

This original Brown Bess musket is an East India Pattern musket (3rd model) as it has a 39 inch barrel, a brass side plate on the opposite side of the lock and has no tail to it. The tang on the butt plate is also short. The lock mechanism reveals that this musket has been converted to a percussion cap musket, which became popular in the 1820s. It was assembled at the Tower of London and is engraved with a crown, "GR" and an "X", on the top of the barrel. There is also a ".W. Reg.t" marking on the side of the barrel. This rare musket is typical of the muskets carried by British and Canadian soldiers during the War of 1812 and the Rebellion of 1837.

Image of Niagara Falls n.d.

In 1818 Parkhurst Whitney built stairs leading to the river’s edge at Prospect Point. In 1825 Porter Brother replaced that staircase with a spiral one. In 1844 Whitney started a water powered incline railway there although the staircase was also used until 1890. In 1906 the water wheel was replaced by an electric power plant. There were lower buildings which included Shadow of the Rock which was a concession stand and also rented raincoats to the tourists. This was destroyed by fire and ice in 1892 and replaced by a chalet-style building in 1894-95. On July 6th, 1907 a cable on the incline railway broke. One person was killed and several sustained injuries. An elevator was constructed and it opened in January of 1910. It was condemned in 1954 when water entered the shaft, this was at the time of the collapse of Prospect Point which occurred at 4:50 pm. on July 28, 1954. This photograph was taken prior to 1954. Today the New York State Observation Tower stands at Prospect Point and The Maid of the Mist boat ride is available from the base of the tower. with information from: Niagara Falls Canada: a History by the Kiwanis Club of Stamford, Ontario

Proposal for Construction of Brock’s Monument, Queenston, newspaper fragment, 1824

Brock’s Monument is owned by Parks Canada and maintained by the Niagara Parks Commission in collaboration with the Friends of Fort George and Niagara National Historic Sites. It is located in Queenston Heights Park atop the Niagara Escarpment. On March 14, 1815, Parliament passed an act to erect a monument to the memory of General Isaac Brock. A design by engineer Francis Hall was selected. He envisioned a 135 ft. tall Tuscan column, made out of stone with a winding staircase inside. By the spring of 1824, work had begun on the monument. In June of that year, the cornerstone was laid and William Lyon Mackenzie was in attendance at the ceremony. It was on October 13th, 1824 (the anniversary of Brock’s death) that 6000 people traveled to Queenston to inter the remains of Brock and Lieutenant-Colonel Macdonell. This was the second burial for both. After 3 years the tower had reached 135 feet, but there was no inscription at the base, the fence around the observation deck had not been installed and there was no statue of Brock. Hall submitted a plan to finish the statue, but he was turned down and a simple ornament was placed where the Brock statue should have been. A massive blast of gunpowder destroyed the monument in 1840. It is alleged that an American sympathizer with the Upper Canada Rebellion set off the blast. Brock and Macdonell’s bodies were reburied in the Hamilton Family Cemetery in Queenston. The present monument was rebuilt in 1853. William Thomas (designer of St. Michael’s Cathedral in Toronto) was the architect. Brock and Macdonell were once again laid to rest in separate vaults at the statue. In 1968, Brock’s Monument was declared a national historical site. In 2005, it was closed to the public due to safety concerns, but it reopened in 2010.

Arthur A. Schmon fonds

Arthur Albert Schmon was born in 1895 in Newark, New Jersey. During his studies at Barringer High School in Newark, he met Eleanore Celeste Reynolds who was to become his wife in August of 1919. Mr. Schmon studied English literature at Princeton and graduated with honours in 1917. That same year, Mr. Schmon joined the United States Army where he served under Colonel McCormick as an adjutant in field artillery in World War I. In 1919, he was discharged as a captain. Colonel McCormick (editor and publisher of the Chicago Tribune) offered Schmon a job in his Shelter Bay pulpwood operations. Mr. Schmon accepted the challenge of working at this lonely outpost on the lower St. Lawrence River. Schmon was promoted to Woodlands Manager in 1923. In 1930, he became the General Manager. This was expected to be a seasonal operation but the construction of the mill led to the building of a town (Baie Comeau) and its power development. All of this was accomplished under Schmon’s leadership. In 1933, he was elected the President and General Manager of the Ontario Paper Company. He later became the Chairman and Chief Executive Officer. Arthur Schmon made his home in St. Catharines where he played an active role in the community. Schmon was a member of the Founders’ Committee at Brock University and he was a primary force behind the establishment of a University in the Niagara Region. The Brock University Tower is named after him. He also served as Chairman of the St. Catharines Hospital Board of Governors for over 15 years, and was responsible for guiding the hospital through a 3 million dollar expansion program. He was a Governor of Ridley College and an Honorary Governor of McMaster University in Hamilton. Mr. Schmon died of lung cancer on March 18, 1964. He had been named as the St. Catharines’ citizen of the year just one week earlier. Mr. Schmon had 2 sons Robert McCormick Schmon, who was chairman of the Ontario Paper Co. Ltd., St. Catharines, Canada, and the Q.N.S. Paper Co., Baie-Comeau, Canada. He was also director of a Chicago Tribune Co. He died at the age of 61. Another son, Richard R. Schmon, was a second lieutenant in the 313th Field Artillery Battalion, 80th Infantry Division in World War II. He was listed as missing in action on November 5, 1944.

The Rapids, Niagara

The description of the image reads "No. 115 - The Rapids, Niagara - From the Terrapin Tower". On the reverse it reads "The Rapids, Niagara, From the Terrapin Tower (taken instantaneously). From this commanding point of view the rapids are seen to great perfection - the Tower standing just on the edge of the Horse-shoe Fall. Some idea of the rapidity with which these waters hurry onward to the mighty abyss may be formed from the fact that the river descends nearly fifty-one feet in a distance of three-quarters of a mile. Gathering force as they approach nearer the edge of the Falls, they dash and foam amid the rocks which speck their surface, and with torturous writhes dash onward with a fury grand and beautiful in the extreme. Whole flocks of water-fowl have often been seen going to destruction among these rapids. Pleased with being carried by the stream, they have indulged in the pleasure till the rapidity of the current has rendered it impossible for them to rise and thus have they been carried down and washed over the Fall. At one time during the months of September and October, sufficient quantities of dead water-fowl have been found every morning below the Fall to afford ample subsistence for the garrison at the fort. The bodies of bears, deer, and other animals have also been found."

Niagara Falls Handbill Collection, 1838-1886, n.d. (non-inclusive)

According to legend, the Burning Springs were discovered by early natives in the Niagara Peninsula. Bridgewater Mills was built on the site of the spring. During the excavation of the factory; workmen uncovered the spring. Samuel Street and Thomas Clark recognized the potential of this as a tourist attraction so they built a wooden shelter over the spring. The spring was covered with a barrel with a pipe protruding from it. This became the first tourist attraction at Niagara. The Cave of the Winds was a cavern located behind the Bridal Veil Fall. It was originally named the Aeolus Cave. In 1920, a sudden rock fall from the ceiling killed 3 tourists. The cave was destroyed in 1955 as it was deemed dangerous. The captain of the Maid of the Mist was usually a farmer who owned the land where the ship docked. In 1846, the first steam powered Maid of the Mist was launched. By 1848, the first suspension bridge was built over the gorge and the main purpose of the Maid of the Mist was no longer to carry people who needed to travel, but now the focus was on people who wanted to view the Falls at close range.

Studies on the Vertical Structure of Horizontal Wind Variability in the Surface Boundary Layer Over Sriharikota

The present study on the vertical structure of horizontal wind variability in the surface boundary layer over Sriharikota. Based on clock wind speed and direction measuring meteorological tower facility from seven levels in the 100 m layer. The study on wind variability and elliptical approximation of wind hodographs investigated for this tropical coastal station established that Sriharikota is of meso-scale weather entity. Wind variability ratio increases from lower levels to upper levels. In South West monsoon months the station is of high ratio values and it gets affected with meso-scale weather features like thunderstorms. Average total shears are observed greater values than scalar shears. Scalar shears are high in the lowest shear levels compared to upper levels. Semi diurnal types of oscillation in average total shears are found in south west monsoon months. During cyclonic storm passage it is observed that there can be significant difference in mean wind speed from 10 m to 100 m level, but it is not so for peak wind speeds. The variations in wind variability ratio in different months is clearly depicted its strong link to define meso-scale or synoptic –scale forcing domination for this station. Meso-scale forcing is characterized by diurnal wind variability and synoptic- scale forcing by interdiurnal wind variability.

Fabrication and characterisation of polymer optical fibers for smart sensing and optical amplification

The thesis presented the fabrication and characterisation of polymer optical fibers in their applications as optical amplifier and smart sensors.Optical polymers such as PMMA are found to be a very good host material due to their ability to incorporate very high concentration of optical gain media like fluorescent dyes and rare earth compounds. High power and high gain optical amplification in organic dye-doped polymer optical fibers is possible due to extremely large emission cross sections of oyes. Dye doped (Rhodamine 6G) optical fibers were fabricated by using indigenously developed polymer optical fiber drawing tower. Loss characterization of drawn dye doped fibers was carried out using side illumination technique. The advantage of the above technique is that it is a nondestructive method and can also be used for studying the uniformity in fiber diameter and doping. Sensitivity of the undoped polymer fibers to temperature and microbending were also studied in its application in smart sensors.Optical amplification studies using the dye doped polymer optical fibers were carried out and found that an amplification of l8dB could be achieved using a very short fiber of length lOcm. Studies were carried out in fibers with different dye concentrations and diameter and it was observed that gain stability was achieved at relatively high dye concentrations irrespective of the fiber diameter.Due to their large diameter, large numerical aperture, flexibility and geometrical versatility of polymer optical fibers it has a wide range of applications in the field of optical sensing. Just as in the case of conventional silica based fiber optic sensors, sensing techniques like evanescent wave, grating and other intensity modulation schemes can also be efficiently utilized in the case of POF based sensors. Since polymer optical fibers have very low Young's modulus when compared to glass fibers, it can be utilized for sensing mechanical stress and strain efficiently in comparison with its counterpart. Fiber optic sensors have proved themselves as efficient and reliable devices to sense various parameters like aging, crack formation, weathering in civil structures. A similar type of study was carried out to find the setting characteristics of cement paste used for constructing civil structures. It was found that the measurements made by using fiber optic sensors are far more superior than that carried out by conventional methods. More over,POF based sensors were found to have more sensitivity as well.

Techniques for Enhancing Wind Energy Generation - A CFD Based Multibody Dynamics Approach in Horizontal Axis Wind Turbines

Wind energy has emerged as a major sustainable source of energy.The efficiency of wind power generation by wind mills has improved a lot during the last three decades.There is still further scope for maximising the conversion of wind energy into mechanical energy.In this context,the wind turbine rotor dynamics has great significance.The present work aims at a comprehensive study of the Horizontal Axis Wind Turbine (HAWT) aerodynamics by numerically solving the fluid dynamic equations with the help of a finite-volume Navier-Stokes CFD solver.As a more general goal,the study aims at providing the capabilities of modern numerical techniques for the complex fluid dynamic problems of HAWT.The main purpose is hence to maximize the physics of power extraction by wind turbines.This research demonstrates the potential of an incompressible Navier-Stokes CFD method for the aerodynamic power performance analysis of horizontal axis wind turbine.The National Renewable Energy Laboratory USA-NREL (Technical Report NREL/Cp-500-28589) had carried out an experimental work aimed at the real time performance prediction of horizontal axis wind turbine.In addition to a comparison between the results reported by NREL made and CFD simulations,comparisons are made for the local flow angle at several stations ahead of the wind turbine blades.The comparison has shown that fairly good predictions can be made for pressure distribution and torque.Subsequently, the wind-field effects on the blade aerodynamics,as well as the blade/tower interaction,were investigated.The selected case corresponded to a 12.5 m/s up-wind HAWT at zero degree of yaw angle and a rotational speed of 25 rpm.The results obtained suggest that the present can cope well with the flows encountered around wind turbines.The areodynamic performance of the turbine and the flow details near and off the turbine blades and tower can be analysed using theses results.The aerodynamic performance of airfoils differs from one another.The performance mainly depends on co-efficient of performnace,co-efficient of lift,co-efficient of drag, velocity of fluid and angle of attack.This study shows that the velocity is not constant for all angles of attack of different airfoils.The performance parameters are calculated analytically and are compared with the standardized performance tests.For different angles of ,the velocity stall is determined for the better performance of a system with respect to velocity.The research addresses the effect of surface roughness factor on the blade surface at various sections.The numerical results were found to be in agreement with the experimental data.A relative advantage of the theoretical aerofoil design method is that it allows many different concepts to be explored economically.Such efforts are generally impractical in wind tunnels because of time and money constraints.Thus, the need for a theoretical aerofoil design method is threefold:first for the design of aerofoil that fall outside the range of applicability of existing calalogs:second,for the design of aerofoil that more exactly match the requirements of the intended application:and third,for the economic exploration of many aerofoil concepts.From the results obtained for the different aerofoils,the velocity is not constant for all angles of attack.The results obtained for the aerofoil mainly depend on angle of attack and velocity.The vortex generator technique was meticulously studies with the formulation of the specification for the right angle shaped vortex generators-VG.The results were validated in accordance with the primary analysis phase.The results were found to be in good agreement with the power curve.The introduction of correct size VGs at appropriate locations over the blades of the selected HAWT was found to increase the power generation by about 4%

Agricultural, architectural and archaeological evidence for the role and ecological adaptation of a scattered mountain oasis in Oman

The recent discovery of the monumental 5000 years old tower tombs on top of the up to 1850 m high Shir plateau has raised numerous questions about the economic and infrastructural basis of the agro-pastoral-piscicultural society which likely has constructed them. The scattered oasis settlement of Maqta, situated just below the towers in a rugged desert environment has therefore been studied from 2001 to 2003 to understand its prehistoric and present role along the ancient trade route which connected the inner-Omani Sharqiya across the southern Hajar mountains with the ocean port of Tiwi. Maqta consists of a central area with 59 buildings and 12 scattered temporary settlements comprising a total of about 200 semi-nomadic inhabitants and next to 900 sheep and goats. The 22 small springs with a flow rate between 5 and 1212-l h^-1 are watering 16 terrace systems totaling 4.5 ha of which 2.9 ha are planted to date palms (Phoenix dactylifera L.), 0.4 ha to wheat landraces (Triticum durum and Triticum aestivum) during the cooler winter months, 0.4 are left fallow and 0.8 h are abandoned. During a pronounced drought period from 2001 to 2003, the springs’ flow rate declined between 38% and 72%. Most of the recent buildings of the central housing area were found empty or used as temporary stores by the agro-pastoral population watching their flocks on the surrounding dry mountains. There is no indication that there ever was a settlement older than the present one. A number of Hafit (3100–2700 BC) and Umm an-Nar (2700–2000 BC) tombs just above the central housing area and further along one of the trade routes to the coast are the only indication of an old pastoral landuse in Maqta territory where oasis agriculture may have entered only well after 1000 AD. With this little evidence of existence during the 3rd millennium BC, Maqta is unlikely to have played any major role favouring the construction of the nearby monumental Shir tower tombs other than providing water for herders and their flocks, early migrant traders or tower tomb constructors.

Transformación cultural en redes de cooperación empresarial

Ante la globalización y las nuevas tendencias de consumo que se han venido desarrollando a través de los años, las diferentes firmas en el mundo se han visto en la necesidad de buscar estrategias que les permita ser productivas generando más valor a los consumidores. En este sentido, ha surgido la necesidad de trabajar de manera conjunta y a su vez crear lazos de cooperación entre las diferentes organizaciones para el logro de mejores resultados. Las redes empresariales son una opción de integración de procesos y recursos para las organizaciones, sin embargo durante la creación de esta se generan cambios organizacionales que impactan en factores como la cultura organizacional. El cambio en la cultura organizacional se produce de manera gradual o abrupta según la forma de cooperación que ejecuten las empresas o por el contexto externo al cual pertenezca la organización. Así mismo, el líder es el encargado de gestionar el cambio en los valores (núcleo de la cultura), prácticas o la filosofía de las organizaciones; sin el apoyo de los líderes el fracaso de una cultura organizacional en una empresa, red, clúster o alianza será incuestionable.

Revisión sistemática de la literatura: efecto de los rellenos inyectables en la región periorbitaria

Introducción: El conocimiento actual de la fisiopatología del envejecimiento periorbitario justifica la aplicación de materiales de relleno inyectables, dado que se enfocan en la restauración del volumen perdido en esta zona, convirtiéndose en una excelente alternativa a procedimientos quirúrgicos que remueven el tejido excedente. Sin embargo los efectos y la seguridad de esta naciente tendencia terapéutica aún no se sustentan en una sólida base científica. El objetivo de esta revisión es identificar el material de relleno inyectable más adecuado para el manejo de los defectos volumétricos estéticos de la región periorbitaria. Metodología: Se realizó una búsqueda exhaustiva de los artículos indexados publicados del 1º de enero de 2.000 al 30 de septiembre de 2.013, en diversas bases de datos electrónicas, se seleccionaron catorce publicaciones, se extrajo la información referente a datos demográficos, la intervención, el seguimiento y los desenlaces y se realizó un análisis de 14 estudios que cumplieron los criterios. Resultados: Todos los artículos incluidos poseían un bajo nivel de evidencia y del grado de recomendación. Todos los materiales de relleno se asociaron a altos niveles de satisfacción para el paciente, adecuada mejoría de la apariencia estética y similares efectos colaterales, el ácido hialurónico fue el material de relleno inyectable más utilizado en la región periorbitaria. Discusión: Los materiales de relleno inyectable mejoran los defectos volumétricos estéticos de la región periorbitaria pero es necesaria mayor evidencia para determinar el tipo relleno más apropiado para esta condición.
