The court accepted deputy attorney-general Rizwan Ahmed Siddiqui’s argument that the ban was imposed after the declaration of a state of emergency giving the government the right to take any action to maintain law and order.The Pakistan Federal Union of Journalists said the ruling was a message from the government that the ban, which threatens 1,200 jobs, was not going to be lifted any time soon. Geo TV is part of the Jang media group. Its channels are the only ones still subject to the cable distribution ban imposed when the state of emergency was declared on 3 November.______________________________________30.11.2007Open letter to Musharraf saying it is time to allow Geo TV and independent radios to resume broadcastingReporters Without Borders wrote today to President Pervez Musharraf asking him to quickly rescind his ban on the Geo TV group’s various television stations and two independent radio stations, Power99 FM and Mast Fm 103.Mr. Pervez MusharrafPresidentIslamabadRepublic of PakistanDear Mr. President,The authorities in Dubai have just given the privately-owned TV station Geo News permission to resume broadcasting from the Emirate but its programmes are still banned in Pakistan. Your government is also preventing broadcasting by two privately-owned radio stations, whose equipment was seized when the state of emergency was imposed.We hail the Dubai government’s decision to restore Geo News’s rights. Your government must now quickly follow this example and allow Pakistani cable operators to resume distribution of all of Geo TV’s stations. Similarly, the sanctions that were unfairly imposed on the Pakistani news radio stations, Power99 FM and Mast FM 103, must be lifted immediately.Amina Rustamani of the Dubai Media Centre announced yesterday that the Geo TV’s Geo News is again authorised to broadcast from the Emirate. “Geo News will resume broadcasting at midnight from the Dubai Media Centre following productive discussion between the two parties,” Rustamani said. In Pakistan, the only people with access to Geo TV’s stations are those with satellite dishes, the importation of which is restricted.As well as blocking Geo News, your government has also banned the broadcasts of the group’s sports, entertainment and youth channels. “They are trying to strangle us financially by all possible means,” Geo TV president Imran Aslam told us in a letter. “We are losing half a million dollars a day, a figure the government is well aware of and which must have been factored into its calculations,” he wrote. “We are ready to dialogue with honour, but we will not submit to any humiliating accord and to conditions that undermine our credibility.”On 5 November, Geo TV petitioned the Sindh high court to lift the ban, but the government’s representative is sidestepping any substantive debate and on 27 November, the government again claimed that it did not know why the station was blocked.The Association of Independent Radio (AIR) has condemned the plight of Power99 FM and Mast FM 103 resulting from the seizure of their equipment on 3 November. “It was the editorial line of these two radio stations, above all, the attention they paid to current affairs, that prompted their closure,” AIR chairman Najib Ahmed said. Employees at the two stations told Reporters Without Borders that the government has done nothing to enable them to resume broadcasting. Although they were very popular, both because of their own news programmes and their retransmission of the Urdu-language news programmes of the BBC and Deutsche Welle, they are now on the verge of bankruptcy.We are shocked by the methodical way your government has persecuted Geo TV and the independent radio stations. It seems that the sanctions aimed at bankrupting these independent companies are linked to their refusal to bow to certain dictates, in particular, the code of conduct established after the declaration of the state of emergency.Mr. President, the arbitrary manner in which these popular and respected news media are being treatment is having disastrous consequences for your country’s international image and for the hundreds of Pakistani journalists who risk losing their jobs.As you have announced that the state of emergency is to be lifted soon, we urge you, as a goodwill gesture, to restore all of Geo TV’s stations as well as Power99 FM and Mast FM 103.We trust in your commitment to press freedom.Sincerely,Robert MénardSecretary-General January 28, 2021 Find out more
Ambient carbon monoxide (CO) and meteorological parameters measured at the Egham (EGH) semi-rural site in SW London during 2000–2015 have permitted wind sector analysis of diurnal and seasonal cycles, and interpretation of long-term trends. CO daily amplitudes are used as a proxy for anthropogenic emissions. At EGH, morning and evening peaks in CO arise from the dominant contribution of road transport sources. Smaller amplitudes are observed during weekends than weekdays due to lower combustion emissions, and for mornings compared to evenings due to the timing of the development and break-up of the nocturnal inversion layer or planetary boundary layer (PBL). A wavelet transform revealed that the dominant mode of CO variability is the annual cycle, with apparent winter maxima likely due to increased CO emissions from domestic heating with summer minima ascribed to enhanced dispersion and dilution during the annual maximum of PBL mixing heights. Over the last two decades, both mitigation measures to reduce CO emissions and also a major switch to diesel cars, have accompanied a change at EGH from the dominance of local diurnal sources to a site measuring close to Atlantic background levels in summer months. CO observed in the S and SW wind sectors has declined by 4.7 and 5.9 ppb yr−1 respectively. The EGH CO record shows the highest levels in the early 2000s, with levels in E and calm winds comparable to those recorded at background stations in Greater London. However, since 2012, levels in S-SW sector have become more comparable with Mace Head background except during rush-hour periods. Marked declines in CO are observed during 2000–2008 for the NE, E, SE (London) and calm wind sectors, with the smallest declines observed for the S, SW and W (background) sectors. For the majority of wind sectors, the decline in CO is less noticeable since 2008, with an apparent stabilisation for NE, E and SE after 2009. The EGH CO data record exhibits a similar but slower exponential decay, but from a much lower starting concentration, than do CO data recorded at selected monitoring sites in urban areas in SE England. CO/CO2 residuals determined using a 1 h window data in the diurnal cycle demonstrate a clear decline in CO from 2000 to 2015 during daily periods of increased vehicle traffic, which is consistent with a sustained reduction in CO emissions from the road transport sector.
Breakthrough view of colliding neutron stars reveals origins of gold, platinum, and other heavy elements Worlds of promise Related For students, educators, physicians, and X-wing lovers, future of virtual reality dazzles Cassiopeia A, the youngest known supernova remnant in the Milky Way, is the remains of a star that exploded almost 400 years ago. The star was approximately 15 to 20 times the mass of our sun and sat in the Cassiopeia constellation, almost 11,000 light-years from earth.Though stunningly distant, it’s now possible to step inside a virtual-reality (VR) depiction of what followed that explosion.A team led by Kimberly Kowal Arcand from the Harvard-Smithsonian Center for Astrophysics (CfA) and the Center for Computation and Visualization at Brown University has made it possible for astronomers, astrophysicists, space enthusiasts, and the simply curious to experience what it’s like inside a dead star. Their efforts are described in a recent paper in Communicating Astronomy with the Public.The VR project — believed to be the first of its kind, using X-ray data from NASA’s Chandra X-ray Observatory mission (which is headquartered at CfA), infrared data from the Spitzer Space Telescope, and optical data from other telescopes — adds new layers of understanding to one of the most famous and widely studied objects in the sky.“Our universe is dynamic and 3-D, but we don’t get that when we are constantly looking at things” in two dimensions, said Arcand, the visualization lead at CfA.,The project builds on previous research done on Cas A, as it’s commonly known, that first rendered the dead star into a 3-D model using the X-ray and optical data from multiple telescopes. Arcand and her team used that data to convert the model into a VR experience by using MinVR and VTK, two data visualization platforms. The coding work was primarily handled by Brown computer science senior Elaine Jiang, a co-author on the paper.The VR experience lets users walk inside a colorful digital rendering of the stellar explosion and engage with parts of it while reading short captions identifying the materials they see.“Astronomers have long studied supernova remnants to better understand exactly how stars produce and disseminate many of the elements observed on Earth and in the cosmos at large,” Arcand said.When stars explode, they expel all of their elements into the universe. In essence, they help create the elements of life, from the iron in our blood to the calcium in our bones. All of that, researchers believe, comes from previous generations of exploded stars.In the 3-D model of Cas A, and now in the VR model, elements such as iron, silicon, and sulfur are represented by different colors. Seeing it in 3-D throws Cas A into fresh perspective, even for longtime researchers and astronomers who build models of supernova explosions.“The first time I ever walked inside the same data set that I have been staring at for 20 years, I just immediately was fascinated by things I had never noticed, like how various bits of the iron were in different locations,” Arcand said. “The ability to look at something in three dimensions and being immersed in it just kind of opened up my eyes to think about it in different ways.”The VR platforms also opens understanding of the supernova remnant, which is the strongest radio source beyond our solar system, to new audiences. VR versions of Cas A are available by request for a VR cave (a specially made room in which the floors and walls are projection screens), as well as on Oculus Rift, a VR computer platform. As part of this project, the team also created a version that works with Google Cardboard or similar smartphone platforms. In a separate but related project, Arcand and a team from CfA worked with the Smithsonian Learning Lab to create a browser-based, interactive, 3-D application and 360-degree video of Cas A that works with Google Cardboard and similar platforms.“My whole career has been looking at data and how we take data and make it accessible or visualize it in a way that adds meaning to it that’s still scientific,” Arcand said.VR is an almost perfect avenue for this approach, since it has been surging in popularity as both entertainment and an educational tool. It has been used to help medical staff prepare for surgeries, for example, and video game companies have used it to add excitement and immersion to popular games.Arcand hopes to make Cas A accessible to even more people, such as the visually impaired, by adding sound elements to the colors in the model.Reaction to the VR experience has been overwhelmingly positive, Arcand said. Experts and non-experts alike are hit by what Arcand calls “awe moments” of being inside and learning about something so massive and far away.“Who doesn’t want to walk inside a dead star?” Arcand said.This research was supported with funding from NASA.
