The Comptroller and Auditor General (CAG), India’s apex auditing agency has slammed Gujarat government in its five different reports, for mismanagement of the state’s financial resources for the financial year ended 31 March, 2013.The reports were presented in the assembly on Friday, which revealed that the state government port’s policy of 1995 was not being implemented 15 years later.In its audit report on the ‘Economic Sector’, CAG noted that Gujarat Maritime Board applied incorrect wharfage fees under the Captive jetty Agreement with Reliance Petroleum Limited, which led to the recovery of ₹649.29 crore.CAG also revealed that the Gujarat Urja Vikas Nigam Limited did not fix delivery points after the finalization of power purchase agreement, which led to undue benefit of ₹587.50 crore to Essar Power Gujarat Limited, according to The Times of India.CAG said the non-monitoring of the construction quay in phase 1 of Adani Group-owned Mundra port led to short recovery of ₹118.12 crore. Moreover, it was also revealed that Gujarat government made excessive payments for solar power in the state.Additionally, the report about the state’s micro-financial management, observed,”… the non-submission of utilization certificates of Rs 9,121.46 crore indicated the lack of proper monitoring by government departments in utilization of grants.”It also condemned the Gujarat government for poor financial management and budgetary control and pointed that in two instances, grants amounting to ₹13049.67 remained unused.The Highlights of CAG’s report regarding Gujarat:Deficiencies in financial managementLoopholes in Jail SecurityHeritage: Monumental ApathyProfessionalism crunch in state Public sector unitsStaff shortage in Engineering CollegesGirls education scheme bungledUndue benefits to corporate sectorPoor tax recoveryRenewable energy burden
Hina Khan at Cannes Film Festival 2019ReutersTelevision actress Hina Khan dazzled like a diamond as she made her debut at Cannes Film Festival 2019 on Wednesday, May 15. Donning a grey shimmery gown with a plunging neckline and a gathered train, Hina walked the red carpet wearing a bright smiled and waving at the photographers.The actor is at Cannes for the screening of her short film, Lines, which is based on the Kargil War. She attended the screening of sci-fi drama Bacurau on Wednesday.The gorgeous actress, who made her TV debut with Yeh Rishta Kya Kehlata Hai, picked out her favourite moment from her Cannes debut and posted it on her social media page with a caption that read: “The picture is just not “a” picture.”As soon as Hina made her Cannes debut, Twitter burst out in praise. A user wrote, “HINA KHAN slayed omg wow” while another user said, “Okay so i could just get these Glimpses of #HinaKhan for you exclusively at #Cannes2019 She was looking like a Diva.” Just like every year, Aishwarya Rai Bachchan, Sonam Kapoor and Deepika Padukone will also attend the Cannes Film Festival 2019.On Sunday, Hina shot for her last episode of the popular TV show Kasautii Zindagii Kay 2 where she played the role of Komolika. Her co-stars including Erica Fernandes, Parth Samthaan, Pooja Banerjee among others had organised a mini farewell on the sets and wished her luck for future ventures. A few of the clicks were shared on Instagram. Before the big Cannes event, Hina also shot for an upcoming video song by Arijit Singh in Delhi. She is paired alongside her best friend and actor Priyank Sharma in the video.
Share Evan Vucci/APPresident Donald Trump listens during a roundtable on immigration policy in California, in the Cabinet Room of the White House, on Wednesday.President Donald Trump and Democratic critics traded outraged, sometimes plainly false accusations about immigration as the debate over “lost” children and the practice of separating families caught crossing the border illegally reached a new boiling point.The White House on Tuesday wrongly blamed Democrats for forcing Trump’s administration to separate children from parents. Liberal activists and others, including some from media outlets, tried to highlight the issue by tweeting photos of young people in steel cages that actually were taken during the Obama administration. Others seized on reports the government had “lost” more than 1,000 children, though that wasn’t quite the case.It all comes just in time for the midterm elections as Republicans and Democrats try to rally core voters by pointing fingers at one another. Trump won the presidency promising to build a wall along the southern border and end illegal immigration, and the White House believes stressing the same issues will drive voters to the polls and help the GOP hang on to their majorities in the Senate and House.The White House is “really beating the immigration drum in the lead-up to the midterm elections as a rallying cry and as a way of mobilizing voter support for Trump and the candidates that he chooses,” said Doris Meissner, a senior fellow at the nonpartisan Migration Policy Institute and former commissioner of the U.S. Immigration and Naturalization Service during the Clinton administration. “It does seem to provoke a ratcheting up across the board.”Indeed, the situation grew so hostile over the holiday weekend that the president’s elder daughter, White House adviser Ivanka Trump, came under fire for tweeting a photo of herself and her youngest son in their pajamas Sunday morning.“Focus on what is before you, on what you can control and ignore the trolls!” she later wrote.During a White House conference call Tuesday, senior adviser Stephen Miller contended “the current immigration and border crisis” is “the exclusive product of loopholes in federal immigration law that Democrats refuse to close.”That was after Trump lit up social media over the weekend by falsely claiming there was a “horrible law” that separates children from their parents after they cross the border illegally. He had said previously that “we have to break up families” at the border because “the Democrats gave us that law.”But there’s no law mandating that parents must be separated from their children, and it’s not a policy Democrats have pushed or can change alone as the minority in Congress. The tactic’s increased use is being driven by Trump’s administration, which recently announced a new “zero-tolerance policy” in which it will press criminal charges against all people crossing the border illegally, even if they have few or no previous offenses. More children are expected to be separated from their parents as a result.A Customs and Border Protection official told lawmakers last week that 658 children had been separated from their parents at the border from May 6 to May 19 as the parents face charges. That’s in addition to hundreds more who were estimated to have been removed from their parents since October.The practice has drawn condemnation from Trump critics, who have long accused him of supporting inhumane policies in his efforts to crack down on illegal immigration.“He actually called the practice horrible. If he thinks it’s so horrible then he ought to just end it and not make the children a negotiating tool,” said Lee Gelernt, deputy director of the American Civil Liberties Union’s Immigrants’ Rights Project.“It’s never a good idea to separate small children from their parents,” said Rep. Carlos Curbelo, R-Fla. “I cannot defend that, nor do I wish to.”Curbelo is a leader of GOP lawmakers trying to force House immigration votes next month over leaders’ objections.Trump foes made their own missteps in the debate.Over the weekend, some critics of the policy tweeted photos of young-looking immigrants at the U.S.-Mexico border in steel cages and blamed the Trump administration for separating immigrant children from their parents. The problem: The photos were taken by The Associated Press in 2014, when Barack Obama was in office, and the photo captions reference children who crossed the border as unaccompanied minors.How or why the story resurfaced on social media four years after it was published was unclear. But Trump seized on the error.“Democrats mistakenly tweet 2014 pictures from Obama’s term showing children from the Border in steel cages. They thought it was recent pictures in order to make us look bad, but backfires,” Trump tweeted Tuesday. “Dems must agree to Wall and new Border Protection for good of country … Bipartisan Bill!”It’s unclear what “Bipartisan Bill!” Trump might have been referring to.Congress is heading toward an immigration showdown in the House as Republican moderates force a June vote on legislation to protect young “Dreamer” immigrants and beef up border security.GOP leaders are trying to stop the bill, which has robust support from Democrats and some Republicans. They’re worried any legislation that smacks of “amnesty” for immigrants in the U.S. illegally would dampen conservative enthusiasm ahead of the midterms.Instead, House Speaker Paul Ryan and his leadership team are trying to put together an alternative approach that most Republicans would support. But finding common ground remains difficult. Trump so far has not engaged in the Capitol Hill debate, even as he repeatedly insists Congress must act.Also making the rounds on social media over the holiday weekend: Allegations that children placed in custody have been “lost” by federal authorities, which officials say isn’t the case.The allegation, which sparked #WhereAreOurChildren on Twitter, grew out of testimony in April by a federal official that the government had lost track of nearly 1,500 unaccompanied minor children it placed with adult sponsors in the U.S.An official from the Health and Human Services Department told a congressional hearing last month that his department placed follow-up phone calls from October to December to U.S. households that were sponsoring minors who crossed the border without their parents. They reached 86 percent of the children or sponsors, but the department could not verify the whereabouts of 1,475. In some cases, sponsors simply didn’t respond to the follow-up phone call, not surprising because many are themselves in the U.S. illegally and reluctant to speak to authorities.“If you call a friend and they don’t answer the phone, you don’t assume that they’ve been kidnapped,” HHS’ Steven Wagner said.Officials said Tuesday they are planning more thorough screening of both minors and their sponsors, including a fingerprint background check of every sponsor.
Using UV spectrophotometry, Sundarrajan and his peers analyzed the hydrolysis of paraxon and found that the most effective hydrolysis came from oxy-B-CD nanofiber membrane. “The ether group from oxy-B-CD acted as a linker with the benzene ring and optimized the interactions between the catatlyst and the paraxon,” he explained. The scientists made another startling observation: “As the yield of the oxy-B-CD increased, the extent to which the nerve agent stimulant hydrolyzed also increased,” Sundarrajan said. By manipulating the ether group that is between B-CD and IBA, the scientists could cause this increase in oxy-B-CD.The oxy-B-CD broke down paraxon into diethyl phosphoric acid and p-nitorphenol, which changed from the acid base to the base form (p-nitorphenolate). “A highly-stable complex between p-nitrophenolate anion and B-CD occurs, possibly from polarizability and resonance delocalization,” Sundarrajan added. Sundarrajan and his team measured the amount of p-nitrophenol with UV spectrophotometry, finding a maximum at 410 +- 10 nm. In other words, the nanofiber membranes functionalized with oxy-B-CD were effective in decontaminating paraxon.Furthermore, the team of scientists compared the hydrolysis of paraxon with activated carbon to the hydrolysis with oxy-B-CD, as well as the other types of functionalized PVC polymer nanofiber membranes. The team found that the oxy-B-CD was 11.5 times faster than the activated carbon and that the oxy-B-CD was also faster than B-CD, IBA, and the B-CD and IBA combination nanofibers.Manufacturers can add oxy-B-CD nanofiber membranes to woven clothing, leading to decontamination of organophosphorous nerve agents, as well as lighter and more breathable clothing. “Next we are trying to develop non-specific catalysts that will decompose both nerve and blister agents,” Sundarrajan says. By Syeda Z. Hamdani, Copyright 2006 PhysOrg.com Citation: Detoxifying Nerve Agents Using Functionalized Polymer Nanofiber Membranes (2006, July 10) retrieved 18 August 2019 from https://phys.org/news/2006-07-detoxifying-nerve-agents-functionalized-polymer.html A group of scientists from the National University of Singapore published a study in the May 30th issue of Nanotechnology, which developed polymer nanofiber membranes with a synthesized catalyst to detoxify nerve agents. Research fellow Subramanian Sundarrajan, with the University’s Bioengineering Division, and his colleagues wanted a method to detoxify organophosphorus nerve agents, such as Soman, Sarin, and Tabun. “Nerve agents disrupt the human nervous system by inhibiting the actylcholine esterase enzyme,” Sundarrajan said.Currently, protective clothing for OP nerve agents use functionalized activated carbon. Disadvantages to carbon include its heaviness, its ability to hold moisture, and having to dispose of contaminated clothing because of absorption.An important aspect of the study involved the choice of catalyst. “Literature showed that B-CD (B-cyclodextrin) and IBA (o-iodosobenzoic acid) have a history of hydrolyzing nerve agents. We hypothesized that if we synthesized a CD derivative with IBA functionality, it would have better catalytic properties,” Sundarrajan explained.As a result, Sundarrajan and his group chose 3-carboxy-4-iodosobenzyl oxy-B-CD, which was a CD derivative, as one of the catalysts in the experiment. The team also used other variations of B-CD and IBA. The material for the nanofiber membranes was equally vital; in the past, the scientists had experimented with nanofibers spun from cellulose acetate, but found this material to be too fragile.Instead, the scientists used PVC polymer for the nanofibers because of its advantages: PVC has a small fiber diameter, is extremely porous, and has a high surface area. “A high surface area helps in obtaining better reactivity with the catalyst,” Sundarrajan said.For the control portion of the experiment, Sundarrajan and his colleagues electrospun one set of PVC polymers into nanofiber membranes without a catalyst. They also electrospun PVC with B-CD, PVC with IBA, PVC with B-CD and IBA and PVC with oxy-B-CD. All functionalized nanofiber membranes were hydrophilic, with varying static water contact angles: 10 degress for the plain PVC and PVC with IBA, 12 degress for PVC with B-CD, 7 degrees for PVC with B-CD and IBA, and 9 degrees for PVC with the oxy-B-CD.To test the effectiveness of the functionalized nanofibers, the scientists chose paraxon, a nerve agent stimulant that can be analyzed with UV spectrophotometry. They dipped the nanofiber membranes in three different concentrations of paraxon, 10mM, 25mM, and 50mM, at 25 degrees C, as well as one additional beaker which had unhydrolyzed paraxon for comparison.
