July 10, 2020 Español, Press Release, Public Health En el día de la fecha, el Gobernador Tom Wolf, el Secretario del Departamento de Desarrollo Comunitario y Económico, Dennis Davin, y el Secretario de Agricultura, Russell Redding, recordaron a los residentes de Pennsylvania que deben usar máscaras mientras compran y comen en restaurantes para proteger y apoyar a nuestras empresas locales.“El uso de máscaras es mucho más que un requisito. Es una señal de apoyo y respeto hacia nuestras empresas locales”, dijo el Gobernador Wolf. “Las empresas de Pennsylvania han hecho importantes sacrificios en los últimos meses y ahora ellos confían en que nosotros, como consumidores, podemos ayudarlos a mantener las puertas abiertas. Usar una máscara protege a todos del virus y muestra respeto y apoyo por las empresas y sus empleados. Ellos usas máscaras todos los días y adoptan otras medidas importantes de salud y seguridad para protegernos y brindarnos los bienes y servicios que necesitamos y queremos”.Todas las empresas que funcionan en persona deben cumplir las pautas de seguridad en edificios y en empresas emitidas por la Secretaria de Salud de Pennsylvania y por los Centros para el Control y la Prevención de Enfermedades (CDC). Específicamente, los trabajadores y los clientes deben usar una máscara cuando trabajan, compran y comen en los restaurantes, y los empleadores deben proporcionar a los trabajadores las máscaras que necesiten. La guía para empresas está disponible para las empresas de Pennsylvania.“Pennsylvania está abriendo nuevamente, y con esa libertad viene la responsabilidad. Todos debemos usar máscaras cuando visitamos los restaurantes, salones y tiendas en todo el estado”, dijo el Secretario del DCED, Dennis Davin. “Al pedirles a los clientes que usen máscaras, los dueños de negocios de Pennsylvania están dando un paso adelante para garantizar que sus clientes y los empleados se sientan cómodos y seguros. Para que Pennsylvania siga funcionando, debemos trabajar juntos para detener la propagación del coronavirus”.La investigación demuestra que usar una máscara reduce el riesgo de infección de COVID-19, al tiempo que no usar una máscara aumenta en gran medida las posibilidades de que una persona se infecte con este virus contagioso y mortal.“Queremos que los residentes de Pennsylvania salgan, ya que es importante que nuestra salud mental vuelva a tener un sentido de normalidad. Pero las cosas aún no son normales, y es por eso que deben usar una máscara. Usar una máscara les da libertad y minimiza el riesgo”, dijo el Secretario Redding. “Usen una por su comunidad y sus familias. Usen una máscara para que la cara amigable que ven en el mercado de agricultores cada semana siga estando ahí. Y sobre todo, úsenla para que Pennsylvania pueda seguir avanzando”.El 1 de julio, la Secretaria de Salud la Dra. Rachel Levine firmó una orden que indica la obligatoriedad del uso de máscaras. Permanece vigente.

Month: October 2020
July 10, 2020 Press Release, Public Health Governor Tom Wolf released a weekly status update detailing the state’s mitigation efforts based on the COVID-19 Early Warning Monitoring System Dashboard comparing the seven-day period of July 3 – July 9 to the previous seven days, June 26 – July 2.The dashboard is designed to provide early warning signs of factors that affect the state’s mitigation efforts. The data available on the dashboard includes week-over-week case differences, incidence rates, test percent-positive rates, and rates of hospitalizations, ventilations and emergency room visits tied to COVID-19.“By looking at both statewide status and individual county status, we can take steps to stop increases before they become critical,” Gov. Wolf said. “One thing we know for certain is that we must continue to wear masks and practice social distancing. Risky behavior such as going out without a mask and congregating at a bar or in a crowded setting where social distancing isn’t being practiced are leading to spikes in cases and higher percent-positive rates.”As of Thursday, July 9, the state has seen a seven-day case increase of 4,914; the previous seven-day increase was 4,359.While the statewide percent-positivity rate is at 4.4%, counties with concerning percent-positivity rates include Allegheny (7.9%), Beaver (6.3%), Butler (5.5%), Clarion (14.6%), Fayette (5.2%), Greene (5.4%), Lawrence (5.8%), Lebanon (5.6%), Philadelphia (5.1%), Washington (7.2%), Westmoreland (5.4%) and York (6.3%). Each of these counties bears watching as the state continues to monitor all available data.Today, the Department of Health updated its travel recommendations and frequently asked questions, originally announced on July 2, to include Delaware, Iowa, Kansas and Oklahoma on the list of states recommended for domestic travelers returning from to quarantine for 14 days upon return to Pennsylvania.Gov. Wolf continues to prioritize the health and safety of Pennsylvanians through the COVID-19 pandemic. Pennsylvanians should continue to take actions to prevent the spread of COVID-19, regardless of the status of their county. This includes wearing a mask or face covering anytime they are in public. COVID-19 has been shown to spread easily in the air and contagious carriers can be asymptomatic.Ver esta página en español.

Place Auctioneer Peter Bergin found a new owner for an Alderley home. (AAP image, John Gass)A TRADIE that sold up his childhood home after he got a job in New South Wales became an instant millionaire at auction.Rhys Lawler made the difficult decision to sell the Alderley home he grew up in when he took a job at power company Port Macquarie.With him departing the Sunshine State, 9 Edith St in Alderley was put up to auction, and he found no shortage of people wanting to move into his old digs.“It’s a great house, I bought it off my parents,” Mr Lawler said.“The (suburb) has become very family friendly and relatively sought after.”After some heated bidding between five interested parties in the backyard, the old Queenslander went for $1.021 million.The auction attracted a number of bidders and curious onlookers. (AAP image, John Gass)It was a high price considering the median for a house in the area is currently at $813,750, and he was clearly pleased with how smoothly the sale went.More from newsParks and wildlife the new lust-haves post coronavirus20 hours agoNoosa’s best beachfront penthouse is about to hit the market20 hours agoAgent Matthew Jabs from Place Newmarket said the house was a bit more than you average old Queenslander in a good suburb.“This is a very tightly held street, a lot of the people here have been here for 30 to 40 years,” Mr Jabs said.“If anything comes up it gets a lot of interest.”At 602 sqm it was a lot larger than a lot of other homes in the neighbourhood, and with a recent renovation, the elevated home four bedrooms, a covered deck an office and a living room on each storey.The home has had a dramatic makeover yet retained its original character.Buyers agent for the winning bidder Belinda Shields said the family from Wavell Heights would be the new owners.“It’s a character home which they liked very much, we recognise that Alderley is a very good area especially in this location,” Ms Shields said.9 Edith Street, Alderley was held by the same family for decades.As for Mr Lawler he will have the pick of the litter of Port Macquarie homes when he moved down in a few weeks, with the median house price currently at $570,000.“Yeah, it is a very different market,” Mr Lawler said.
A CONSORTIUM of Union Pacific and two Mexican firms is likely to be sole bidder for a 50-year concession to manage and operate Mexico’s 6400 km Pacifico-Norte Railway. Jorge Silberstein, who is in charge of the FNM privatisation, said last month that no other tenders were expected by the June 19 deadline for technical and financial proposals. ’The group is very solid, very strong, and very professional,’ he noted.Two other firms, Tribasa SA (with RailTex and ITISA of Mexico) and mining company Grupo Mexico SA, have withdrawn from the bidding. Instead Grupo Mexico has joined with UP and construction firm Empresas Ingenieros Civiles Asociados SA. UP officials said the company would take a 10% to 15% stake in the venture. UP earns more than $700m in annual revenue from shipments between the US and Mexico and dominates the market. Last year it was outbid by Kansas City Southern for control of Mexico’s Noreste railway (RG 1.97 p7).The winner of the Pacifico-Norte will also be offered an option to buy the concession for the Chihuahua – Pacific Railway at a price to be set by the government. Following the PN sale, the government plans to auction the concession for the third of the FNM regional operations, the Sureste.The government has appointed IXE Banco SA as financial agent for the outright sale of various FNM branches as short lines. Registrations of interest for the first three were due by May 7, and the sales are expected to proceed in parallel. They are the isolated 71 km Ferrocarril Tejuana – Tecate in the far northwest, in which Railtex has expressed interest, the 320 km Nacozaria short line in Sonora, and a 973 km route linking the states of Coahuila, Durango, Chihuahua and Zatecas. o
INTRO: Longitudinal precast concrete beams laid in stone ballast provide continuous support to the rails and reduced ground pressure for the same overall weight as conventional sleepersBYLINE: Dr Eng Hajime WakuiChief EngineerStructural Engineering GroupJapan Railway Technical Research InstituteFROM THE 1940s to the 1960s, experiments were carried out in France, Japan and the Soviet Union with longitudinal sleepers laid in parallel pairs under the rails. None was successful, and the idea was abandoned in favour of individual transverse concrete sleepers replacing wood. Twin-block concrete sleepers joined by a steel tiebar are also in common use.In 1993, the Structural Engineering Group of Japan’s Railway Technical Research Institute (RTRI) examined the reasons for the failure of longitudinal sleepers. It was concluded that these pioneering designs had not paid enough attention to maintaining the track gauge, and they required a greater weight of concrete than transverse sleepers. Nevertheless, it was considered that the basic principle of placing parallel pairs of sleepers directly beneath the rails was sound.Since then, ladder sleepers have been developed and tested in service. They were installed experimentally in February 1996 on a JR Freight line of 1067mm gauge after extensive tests at RTRI. The length of the experimental section is 100 m, and by June 1997 it had carried 20 million gross tonnes. Tests on a heavy haul version will start shortly at the Association of American Railroads’ Transportation Technology Centre near Pueblo in Colorado.Several designs for different types of track structure have been developed using ladder sleepers. While most will be laid in stone ballast, designs include track resting on a mortar, asphalt or concrete base suitable for viaducts or in tunnels. Patents for ladder track have been filed in a number of countries.Track can be tampedMany attempts have been made to produce concrete trackbeds which require little or no maintenance. While these have been successfully used on structures, notably on Shinkansen routes in Japan and on metros in tunnel, permanent way engineers have been reluctant to abandon stone ballast because of the ease with which the line and level can be adjusted by tamping to compensate for the settlement of earthworks.The fundamental difference between ladder sleepers and concrete trackbeds is that the former are designed to be laid in ballast and tamped by machine to maintain the required rail top level, and adjust the alignment if necessary. Obviously, the tamping heads have to be turned through 90°, but the sleepers are flexible enough to be lifted by a tamping machine and the principle is almost the same as for cross-sleepered track.Pressure exerted on the ballast is much less variable, and as a consequence the rate of settlement is far lower than that experienced with conventional sleepers. The sleeper and rail act together as a composite beam which to some extent bridges across weak spots in the formation. All this points to a big reduction in track maintenance costs.Design structureLadder sleepers are manufactured as two longitudinal concrete beams joined by transverse steel pipes which act as gauge ties. The finished product looks like a ladder laid on the ground – hence the name.The standard distance between two transverse pipes is 2·5m. The minimum unit length is 5m as obviously two pipes are necessary for structural and gauge stability. The maximum is 12·5m (five pipes) weighing about 4 tonnes, which is the most that can be conveniently handled at the work site.At 625mm intervals, pairs of shoulders for Pandrol clips are cast into the top of the sleeper. The rail can therefore be supported continuously, except for a short distance at the sleeper ends. In addition to the rail pad, a continuous ballast mat can be laid under the sleeper.The purpose in having different length units is to enable curved track to be laid. By using an adjustable insulated spacer between the Pandrol shoulder and the rail, or by using Pandrol shoulders on a moveable baseplate, a curve of 200 m radius can be laid using the 5m long units. The 12·5m units can be used on curves over 2 000 m radius.Because of its excellent crack resistance, pretensioned partially-prestressed concrete (PPC) was adopted for the longitudinal beams. Newly developed indented prestressing wires of three or five strands, which have very good adhesion to the concrete, are arranged close to the top and bottom surfaces where cracks are most likely to occur (photo p589). Stress transfer between the indented wires and the concrete relies solely on this bond.The dimensions of the longitudinal beam were mainly dictated by the need to incorporate the cast iron shoulders for the Pandrol clips within the cross-section, which is 400mm wide at the upper surface and 155mm deep under the rail seat (Fig 1).The width is increased on the inside by 30mm where the pipes used as ties enter the beam. These pipes are 76mm in diameter and 9mm thick. They are deformed at the ends to prevent them from rotating or being pulled out of the concrete.With the rail and sleeper acting as a continuous flexible beam, sleeper ends obviously become a weak point where differential movement has to be constrained.RTRI is currently developing a number of types of joint. The aim is to connect the longitudinal beams within a galvanised steel channel using sufficient through bolts to resist the shear forces. However, at intervals it will be necessary to allow longitudinal expansion and contraction of the sleepers to take place at the joints.Because of their configuration, ladder sleepers are highly resistant to track buckling in hot weather. However, they do not offer the same resistance to longitudinal creep as transverse sleepers. As experience shows this to be necessary, transverse steel plates which react against the ballast can be installed between the beams.Test resultsOne benefit of the ladder sleeper is the ability to bridge across weak spots in the subgrade where partial subsidence has occurred. The effect of unsupported gaps 1·8 and 3·6m long symmetrically under both beams and asymmetrically under one side beam was analysed. These calculations were used to determine the crack resistance and the ultimate capacity of the longitudinal beam as well as the diameter and thickness of the pipe.These are extreme cases, and serve to emphasise that ladder sleepers can enhance safety under conditions where the subgrade has partially collapsed, for example after a washout or earthquake.Drop-weight impact tests were performed to simulate the effect of wheel flats. These confirmed that ladder sleepers had been correctly designed to withstand such impacts.As regards ballast pressure, the much more even distribution achieved by ladder sleepers is well brought out by Fig 2. This shows the effect of a bogie exerting 80 kN static wheel load; maximum pressure immediately under the wheels is approximately halved, and the pressure gradient is much smoother.It is therefore no surprise that repetitive loading tests showed settlement rates to be about eight times less under the middle of ladder sleepers compared with conventional track (Fig 3). However, settlement is greater at the ladder sleeper ends, emphasising the need for more development in this area.Heavy haul possibilitiesRTRI has produced a new design for ladder sleepers scaled up for use on heavy haul lines with up to 40 tonne axleloads. A 1067mm gauge version has already been installed within the steel works of Sumitomo Metal Industries in Japan where the axleload is 30 tonnes. The 40 tonne standard gauge version has been installed in the High Tonnage Loop at the AAR’s Pueblo test centre in Colorado.On the new design, the beam width has been increased to 450mm. Rail fastenings are spaced at 750mm intervals, and as there are still four between each gauge tie, these are 3m apart. Sleepers are therefore manufactured in lengths of 6, 9 and 12m.Other track formsThe fact that the rail and sleeper are in continuous contact and act together as a composite beam means that a smaller rail section could support for the same axleload, especially where a heavy rail section such as 70 kg/m is used.The fact that rail is supported at intervals of about 700mm by transverse sleepers introduces vertical wheel motion at sleeper passing frequency, which can be a factor in generating corrugation and noise. Ladder sleepers should therefore reduce both noise and ground-borne vibration, especially when combined with resilient wheels.On viaducts and in tunnels where it is desirable to lay a concrete trackbed, ladder sleepers still offer advantages. They can either be laid on a resilient mat on the track bed, or as a floating track insulated from the trackbed by discrete resilient mountings (left). oCAPTION: A 12·5m long ladder sleeper panel placed on a levelled ballast bed; lifting rings are attached opposite the tubes forming the gauge tiesCAPTION: Tapered insulators with serrations are used to accommodate rail curvatureCAPTION: Arrangement of reinforcing and prestressing wires within a ladder sleeperCAPTION: Fig 1.
