LANCASTER — Antelope Valley Hospital is embarking on Phase 1 of a major expansion, a $90 million plan that includes nearly doubling the size of the emergency room, adding more ICU beds and remaking the hospital entrance. The hospital plans to borrow $30 million to fund the project initially and then pay for the remainder either through revenue generated from the expansion and improved operations or with more loans. “The balance of what we need, the rest of it has to come from operations,” Chief Executive Officer Les Wong said. “We have to improve operations to generate the necessary credit to either borrow the rest of it or use internal cash.” The $90 million encompasses construction, equipment, a contingency fund and fees. Construction is expected to start sometime this year. The 399-bed hospital plans to expand the emergency room by 12,000 square feet and increase the number of beds in the intensive care unit from 21 to 40. “The emergency room is going to have one multi-tier triage system in the middle,” Chief Operating Officer Ed Mirzabegian said. “Patients will go to the emergent side where it’s for emergencies, and the urgent side is for less-acute patients. Right now, everybody is kind of combined together.” Enlarging the emergency room will help with patient flow and allow for separating patients by the seriousness of their condition. The current 24 bays or treatment areas will increase to 55, and two new trauma rooms will be created, Mirzabegian said. Other projects include adding a second cardiac catheterization laboratory with holding rooms and recovery areas, putting in 190 more parking spaces, increasing private beds from 157 to 162, and building a canopied entrance. “It’s a little bit awkward when you pick up and drop off now. We will make a nice circular drive and put a glass canopy on top of that,” Mirzabegian said. — Karen Maeshiro, (661) email@example.com
The two special screenings of ‘A Stranded Nation’ is taking place June 27 at The Lido Theatre, with a screening at 11:30 a.m. and the next at 6:00 p.m.Tickets for each screening is $25.00 per person.For tickets and information, you can call The Lido at 250-785-3011. FORT ST. JOHN, B.C. – This Thursday, June 27, there will be two special screenings of a new documentary at The Lido Theatre.Produced by Heidi McKillop, ‘A Stranded Nation’ is a documentary that addresses the key issues around Canadian oil and gas development and explores the interconnections between oil and gas and everyday life.The documentary features interviews with prominent industry leaders and supporters of the Canadian Natural Resource sector.- Advertisement -McKillop says the goal of the documentary is for people across Canada, particularly young people, to be better informed about oil and gas.She also says Alberta’s concerns should be heard and that the country needs to work together.“Our overall message is that Canada is not an environmental laggard, it’s not dirty oil, that Alberta’s concerns should be heard and that we need to start working together cross-provincially.”Advertisement
Dortmund sold their top-scorer to Arsenal for £56 million ($79 million, 63 million euros), then signed Batshuayi hours later as cover until May.“I am very happy, but the most important thing was the win,” Batshuayi told Eurosport.“It’s my first match, it was always going to be difficult.“I could have scored more but the most important is the win and the three points.“My goal with Dortmund is to keep winning, finishing as high as possible to play in the Champions League next season.”Having already scored 12 goals for Chelsea this season, Batshuayi scored 35 minutes into his Bundesliga debut when he fired home a cross.Cologne equalised with an hour gone, but the 24-year-old Batshuayi showed ice-cool finishing to restore the lead less than two minutes later.He could have finished with a hat-trick having put the ball in the net just before the break, but the video assistant referee (VAR) spotted he was offside.Cologne levelled for the second time when Jorge Mere headed home, but Batshuayi provided the final pass for Andre Schuerrle to hit the winner.The win broke Dortmund’s run of three draws.It lifts them to second in the table, level on 34 points with Bayer Leverkusen and Schalke who play Saturday, behind leaders Bayern Munich.The defeat ends Cologne’s four-match unbeaten run which yielded 10 points to boost survival hopes.Batshuayi grabbed his first goal when Dortmund left-back Jeremy Toljan fired a cross into the box for the Belgian striker to fire home.The pair combined again just before the break when Batshuayi again tapped home, but the goal was ruled offside by the VAR.It was 1-0 at the break, but Cologne drew level on 60 minutes when second-half replacement midfielder Simon Zoller finished off a counter-attack.However, Dortmund replied almost immediately.Christian Pulisic headed down a long ball and Batshuayi robbed Cologne defender Dominique Heintz before firing home from a tight angle.Cologne equalised again on 69 minutes when Mere headed home from a corner.Shuerrle claimed his first league goal for 11 months when Batshuayi spotted the Germany winger free on the right and he smashed home the winner.Swiss centre-back Manuel Akanji, who cost 21.5 million euros ($26.4 million) from Basel last month, made his Dortmund debut in the dying stages off the bench.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Dortmund’s Michy Batshuayi celebrates after scoring during the Bundesliga match between FC Cologne vs Borussia Dortmund © AFP / Patrik STOLLARZBERLIN, Germany, Feb 3 – Michy Batshuayi scored twice on his Borussia Dortmund debut in Friday’s 3-2 Bundesliga win at bottom side Cologne — just two days after signing on loan from Chelsea.Head coach Peter Stoeger, who was sacked by Cologne in December, threw the Belgian striker in at the deep end to replace Pierre-Emerick Aubameyang.
A man who could not accept the break-up of his relationship headbutted his former girlfriend, poured drinks over her and then sent her a series of vile text messages.Kieran Callaghan appeared in court following the attacks on his former partner Martina Mulhern in Letterkenny. The court heard how that although the relationship was brief, 33-year-old Callaghan could not accept the break-up.After the relationship broke down, Callaghan approached Ms MUlhern on a number of occasions.On July 2nd, 2017 in the Warehouse Bar, he approached her on two occasions and poured two drinks over her head.On July 17th, Ms Mulhern was socialising in the Voodoo NIghtclub in Letterkenny when she was approached by Callaghan.He headbutted the woman causing her swelling and bruising to her face.Callaghan, of Garrison Hill in Killygordon also admitted sending a series of disgusting text messages to his former girlfriend.Garda Inspector Barry Doyle said the text messages were very offensive and included “F*** you tramp. You rotten piece of s***. I hope you die a painful one”, “You are a pathetic lowlife scumbag I never loved you” and “I hope you fall off a cliff.”The court was told that Callaghan had previously appeared in court for breaking a window in Ms Mulhern’s home in Ardara on the night he poured drinks over her headSolicitor for the accused, Mr Frank Dorrian, said Callaghan had tendered an apology to Ms Mulhern and that it was sincere.He said his client had been distraught and had experienced emotions of hopelessness and despair after the couple’s break-up.Judge Paul Kelly adjourned the case until January 14th next and asked the court for a probation report and victim impact statement from Ms Mulhern.Man headbutted, poured drink over and sent vile texts to former girlfriend was last modified: November 14th, 2018 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:attackcourtdonegalKieran Callaghanrelationship

Cargo moves around rapidly and ceaselessly in every cell. Some moves in and out of the external membrane, and some moves in and out of organelles and the nucleus. In a system of protected domains surrounded by impermeable membranes, how does the cell control what should pass? Details of the amazing gatekeeping mechanisms embedded in cell membranes have been coming to light for years now. Some recent articles have reported the latest findings. Protective sleeve: One method of getting valid cargo through the membrane gate is to wrap it in a protective sleeve that the gate recognizes. PhysOrg has an illustration from the work of a team at Purdue showing how this works. What comes to mind is a personal subway capsule that shuttles you to an escalator that transfers you safely into a shopping mall without any intruders getting past.Electronic gating: Ions are electrically-charged atoms whose concentration in the cell must be strictly controlled. Compared to the large molecules of the cell, ions of potassium, chlorine and sodium are tiny. Special voltage-sensing gates exist just for them. We reported here on early results from work by Roderick MacKinnon into the structure and function of these ionic gates (see 01/17/2002, 05/29/2002, 05/01/2003, 08/05/2005). The November issue of The Scientist describes ongoing discoveries about one of these voltage-gated channels, the Kv potassium channel. This electronic mechanism contains a pore, a gate and a voltage sensor. In particular, a key helix protein component called S4 undergoes a conformational change to open the gate for the potassium ion. People who enjoy exercise may want to reflect that all nerve and muscle activity depends on the proper control of these ions.Nuclear power plant security: For those wanting to follow up on news about the nucleus, and how it controls the cargo going in and out (see last month’s entry, 11/13/2007, bullet #2), the crew of your nuclear power plant made the cover of Science this week. Laura Trinkle-Mulcahy and Angus I. Lamond reviewed the latest work to get high-resolution images of the complex structures and functions of the nuclear membrane, especially the gates of the nuclear pore complex (NPC).1 Four other articles in the 11/30 issue describe the latest findings about the cell nucleus. A paper by 3 Vanderbilt University scientists specifically addresses the factors involved in crossing the nuclear envelope through the NPC gates.2 For those wanting more information about the sensing mechanism, their article contained color diagrams of the structures. The scientists explained how the gates are regulated at multiple levels – a philosophy common in national security and computer security, too. The “dynamic and diverse” mechanisms control what passes at the gate level, the transport receptor level, and the cargo level. In computer parlance, this might be analogous to requiring a fingerprint, a secure computer, and secure software before you are allowed to login. Another paper in the same issue of Science describes science’s growing realization that the nuclear membrane does far more than let things in and out.3 It is actively involved in cell division, structuring the cytoskeleton, and signaling other processes in the cell. The nuclear envelope is also connected to the endoplasmic reticulum, a structure essential for post-translational modification of proteins. The authors did not mention how these elaborate mechanisms might have evolved, except to say twice that they raise “intriguing questions” and “fundamental questions” about “evolutionary relations” between the parts. The other two papers did not mention evolution at all.ER: emergency room or endoplasmic reticulum: Speaking of the endoplasmic reticulum (a kind of subway system within the cell), Nature reported studies about the transport channels in that organelle.4 “A decisive step in the biosynthesis of many proteins is their partial or complete translocation across the eukaryotic endoplasmic reticulum membrane or the prokaryotic plasma membrane,” began Tom Rapoport (Howard Hughes Medical Institute, Harvard). “Most of these proteins are translocated through a protein-conducting channel that is formed by a conserved, heterotrimeric membrane-protein complex, the Sec61 or SecY complex.” Polypeptides are the pre-protein strings of amino acids emerging from ribosomes, where the translation from RNA occurs. Getting a wobbly chain of molecules through a pore is somewhat akin to threading a needle. Depending on what the cargo binds to, it may get in by one of several ways: the ribosome may simply attach to and inject the nascent polypeptide into the channel, an ER chaperone might pump it in by a ratcheting mechanism, or a molecular machine running on ATP might push the polypeptide through. These are all regulated by a host of assisting proteins that keep in touch through signaling mechanisms. There’s even a plug that closes the channel after the polypeptide is inside. Rapoport provided a diagram of the complicated-looking translocation channel, which is made up of three different protein parts. He called it conserved (unevolved) between all three kingdoms of life, but did not say anything else about evolution – certainly, not anything about how it arose in the first place.Light sensitive: Imagine a receptor on a cell membrane that can respond to one photon of light, and send a signal into the interior. You don’t have to imagine it: it already exists. Rama Ranganathan in Science described the family of G-protein coupled receptors (GPCR) that “occur in nearly every eukaryotic cell and can sense photons, cations, small molecules, peptides, and proteins.”5 How do they do it? The structures of these receptors are just beginning to come to light, and basic models are being formulated. Stay tuned.Most of the articles above said nothing about how these complex transportation systems might have evolved. A review in Nature,6 however, proposed that “the plethora of transport factors found in modern eukaryotes may have also evolved by duplication events, keeping pace with the evolutionary duplication and diverging specialization of the FG nucleoporins in the NPC’s [nuclear pore complex’s] modules.” Noting some similarities in the NPC to clathrin-coated endocytosis, the team of a dozen UK and American scientists suggested that gene duplication was the method of evolution: “the NPC is another example of how a complicated structure can evolve from the duplication, divergence and elaboration of simple ancestral modules,” they claimed. They also downplayed the complexity of the NPC by pointing out some of the proteins are used in a modular fashion. A summary and diagram was posted by PhysOrg. Their evolutionary explanation, however, was based entirely on circumstantial evidence of similarity, not on a chain of plausible steps for how diverse mechanisms, despite some structural similarities, achieved their high levels of functional accuracy.1.

Alber et al, “The molecular architecture of the nuclear pore complex,” Nature 450, 695-701 (29 November 2007) | doi:10.1038/nature06405.The evolutionary speculations in Nature provided nothing to the real scientific work in these papers. They did not help determine the structure, function or dynamics of any of the transport mechanisms. They were mere after-the-fact pipe dreams about how Charlie might be vindicated with a hefty dose of LSD (Let’s Support Darwin). Gene duplication is pitifully incapable of explaining how functional information got into either clathrin-coated endocytosis or nuclear pore transport. A motorcycle and a diesel train have some similarities, too; they both have wheels that rotate and are powered by fuels that have some similarities (hydrocarbons). So what? You can duplicate as many motorcycles as you want, for eternity, and will never get a bullet train. Even if you allow the duplicate motorcycle unlimited free mutations, will that help? Try breaking things at random on the motorcycle and see if you make progress toward train technology. Darwinian evolution is blind, remember. It has no foresight. It is not trying to work toward traindom. Unless each mistake provides some advantage for the here and now, the only likely result is that repeated mutations will leave you stranded on the highway bumming a ride. Sorry we had to waste time on evolution. The focus of this story should be on the amazing mechanisms of the cell, and how modern science is slowly pulling back the cover on the package so we can all, with the fascination of kids at Christmas, look inside and see the words LION-EL.*(Visited 9 times, 1 visits today)FacebookTwitterPinterestSave分享0
What are the limits of science? Many of us envision men and women in white lab coats holding test tubes, studying readouts on instruments, or hacking rocks with picks. A look at headlines from science news sites, though, shows some scientists inserting their opinions in areas traditionally led by scholars in the humanities – and doing so as if their opinions carry the presumed authority of science.Abortion policy: PhysOrg, normally concerned with science news, reprinted an AP story about “abortion foes’ tactics” on their site. The article portrayed crisis pregnancy centers as somehow devious in their attempts to help women find alternatives to abortion, even though New York City’s abortion rate is 41% – the highest in the nation, double the national rate. Reporter Cristian Salazar disparaged the “small number of pregnancy service organizations accused by abortion rights groups and city officials of misleading women about their reproductive health options and disguising themselves as medical clinics,” as if abortion clinics could not be similarly accused. Salazar also mentioned Margaret Sanger having “opened a family planning clinic in Brooklyn in 1916” without any mention of her racist eugenics policies.Wisdom science: To whom do you go for wisdom? A pastor, priest, or rabbi? A holy book? A trusted friend or academic? Never fear; science is here – science in the form of psychology. “What the world needs now? More wisdom,” is the headline of a press release from Concordia University reprinted by PhysOrg. While the headline is true, is science the one to tell anyone how to get it? Isn’t science concerned with natural laws and material processes? Dolores Pushkar defined wisdom as “something that benefits society as a whole as well as the self.” Yet that definition might well be disputed; perhaps it is wise to sometimes stand alone against a whole society bent on evil, as did Bonhoeffer against the Nazi society at the cost of his own life. Paul wrote of a “hidden wisdom” that God performed in Christ’s sacrifice on the cross, a move that at the time seemed futile in Roman society. Does Pushkar, as a scientist, have more wisdom than King Solomon on wisdom? “No single definition of wisdom exists,” the press release admitted. To be sure, the article described how the psychology department was engaging the philosophy department in research on wisdom, and was funded by sources in the Social Sciences and Humanities. Interdepartmental initiatives can be seen as wise moves; science can bring observational and statistical data to bear on questions about wisdom. Yet the press release frequently discussed research being done by Pushkar’s team. At some level, it implies that moral qualities like wisdom are amenable to scientific analysis.Government spending: Live Science – the website name tells what it’s about. Why, then, did Chad Brooks write the following un-scientific headline: “Don’t Like How Tax Dollars Are Spent? Get Used to It.” It’s part of a series the website whimsically calls “$ci-Fi: The Science of Personal Finance,” described as “an ongoing LiveScience series that explores the science of personal finance to help you navigate everyday life.” Again, science seems to be inserting itself into the wisdom business. Can science, though, provide anything more than raw data and statistics? Whose job is it to tell individuals how to live their lives? Does a science site have any more presumptive authority than a financial adviser or a research staffer in a senatorial office? The article provided data about government spending, and made the inductive claim that things are not likely to change soon. Moreover, the article heavily quoted Scott Lilly, a senior fellow at the Center for American Progress, a radically liberal think tank funded by multibillionaire George Soros. So not only is it unclear how science can do any better job of analyzing government spending, or helping individuals navigate everyday life, it here risked soiling its objectivity with accusations of partisanship.Right-to-work: PhysOrg published another “scientific” finding that leans to the left. “Right-to-work laws not only hurt labor unions financially, they also may jeopardize worker safety,” according to “research” by Roland Zullo that conveniently plays into the liberal desires of union bosses to deny freedom of choice to workers. Whether science should be concerned if labor unions are hurt financially seems a moot point. Zullo was quick to paint the unions in a favorable light; “Unions appear to have a positive role in reducing construction industry and occupation fatalities, but only in states without right-to-work laws,” he claimed. At least one reader wrote an angry comment about this article, focusing on the rights of individuals to work without being forced to join a labor union.Girl scout cookies What can science say about Girl Scout cookies? Science Daily apparently thought the presumptive authority of science can judge that traditional Boy Scout and Girl Scout activities are guilty of gender stereotyping. Looking under the hood shows that Science Daily reprinted, under its banner of science, a press release from Sociologists for Women in Science, an organization that supports “feminist sociological research, activism and scholars.” One might think that the standards of scientific objectivity would provide equal time for scholarly views from conservative organizations (perhaps Focus on the Family or the Family Research Council), but a Google search finds not a single mention of these prominent organizations in Science Daily’s listings, but three from the feminist Sociologists for Women in Science and nine from the ultra-liberal Center for American Progress.The science of sin: Update 04/11/2011: in perhaps the most blatant act of usurpation by scientists of the humanities, McMaster University researchers decided they would find “scientific solutions to sin.” Is their solution theological? Do they have a new method of salvation? Are they suggesting moral teachings, or offering psychological counseling? No; their working assumption is that all sin has molecular underpinnings. Their solution, therefore, was to look in the chemical cabinet for antidotes to human moral deficiencies. “Most people are familiar with the seven deadly sins – pride, envy, gluttony, lust, wrath, greed and sloth – but could there be molecular solutions for this daily struggle between good and evil?” (assuming science has the taxonomic tools for such distinctions). Groups of students were told to get out of the theological box and into the scientific box: “By getting students to think outside the box, the aim was to come up with the best molecule and design for a drug, or remedy, that counteracts sin.” Looming questions rise when political ramifications of this research are considered. Who will control the medicine chest? Who will prescribe, and who will partake? The researchers apparently didn’t ask whether there is a drug to combat scientific hubris.Paul Feyerabend, a post-Kuhnian firebrand in philosophy of science, thought that science was a threat to democracy. The Stanford Encyclopedia of Philosophy described his concern:The separation of church and state should therefore be supplemented by the separation of science and state, in order for us to achieve the humanity we are capable of. Setting up the ideal of a free society as “a society in which all traditions have equal rights and equal access to the centres of power” (SFS, p. 9), Feyerabend argues that science is a threat to democracy. To defend society against science we should place science under democratic control and be intensely sceptical about scientific “experts”, consulting them only if they are controlled democratically by juries of laypeople.Law professor Phillip E. Johnson found another Feyerabend quote to end his article on the pretensions of science for world conquest: “Scientists are not content with running their own playpens in accordance with what they regard as the rules of the scientific method, they want to universalize those rules, they want them to become part of society at large, and they use every means at their disposal—argument, propaganda, pressure tactics, intimidation, lobbying—to achieve their aims” (Objections Sustained, Inter-Varsity Press, 1998, p. 66). Feyerabend is widely regarded as extreme in his views, but readers can judge for themselves (as “juries of laypeople”) to what extent his fears have become realized.All the so-called “secular” science news sites and institutions are uniformly leftist in their politics. They are the same ones that give uncritical acceptance of Darwinism. That’s why they are secular; they adore the secular religion Darwin founded, and science is their primary tool for spreading their intolerant bigotry around the world. Let the reader beware. Science does not have to be that way; clearly it was not before the Darwinian revolution. But that’s what it has become. Many individual scientists are not that way, just as many hard-working Americans in labor unions hold views far more conservative than the union leaders, whose views are also uniformly leftist – often radically so, and just as bent on world conquest. One cannot get genuine science out of science news or scientific papers these days without first a severe acid wash. By that, we mean not applying acid to the news, but applying heavy doses of pure water instead, to wash out Darwin’s universal acid that corrodes everything it touches. Another technique is to apply Darwin Acid to Darwinism itself, which causes an implosion, leaving a vacuum that intelligence rushes in to fill.(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0

Log in Building science experts, architects, engineers, and builders from across the U.S., Canada, and Europe gathered in early August in Westford, Massachusetts, for the 19th annual Westford Building Science Symposium, a conference sometimes known as “Summer Camp.”Over three lively days filled with education, networking, and drinking, experts gave ten presentations on a variety of building science topics. You read it here first GBA readers who attended the conference had a sense of déjÃ vu at three of the presentations, since the talks covered topics that GBA has reported on in depth: Ventilating high-rise apartment buildings Lorne Ricketts, a building science engineer at RDH Building Engineering in Vancouver, British Columbia, gave a presentation on research into ventilation systems in a high-rise multifamily building. (Ricketts and his co-author, John Straube, also reported their findings in a paper titled “Corridor Pressurization System Performance in Multi-Unit Residential Buildings.”)For multifamily buildings, mechanical engineers often specify a type of supply ventilation system called a “corridor pressurization” (or “pressurized corridor”) system.Ricketts explained, “A pressurized corridor ventilation system is designed to provide ventilation to the entire building.” This type of ventilation system includes several components:An illustration of a corridor pressurization system is shown in Image #4, below.The engineers who design these supply ventilation systems make several assumptions. The two most important of these assumptions are (a) that the air introduced by the roof-mounted fan is delivered to the common corridors, and (b) that the pressurized corridors deliver fresh air to each apartment. Both assumptions are probably wrong.It turns out that this is a faith-based ventilation system. The designers’ faith is misplaced.

M.P. farmer ‘thrashed by police’ dies Faced with criticism after the police killed five protesting farmers triggering large scale arson and rioting in western Madhya Pradesh, Chief Minister Shivraj Singh Chauhan announced on Friday that he would go on an indefinite fast from Saturday in an attempt to restore peace in the State.The Chief Minister would also be leaving the Vallabh Bhawan (Secretariat) and go to the open grounds to speak to the agitating farmers. “I am not emotionless and therefore, I will undertake a fast at the Dussehra ground on Saturday from 11 a.m.,” he told a press conference in Bhopal.Also Read “I appeal to the farmers to come forward and discuss all the issues with me.”Mr. Chauhan said the State authorities would firmly deal with those trying to disturb the peace. His fast was an attempt to ensure peace was restored at a time when “some elements are out to push the State into violence to realise their political goals.”He, however, reiterated that his government was willing to help the farmers in distress.“The State government is always ready for talks with farmers. I appeal to the farmers to maintain calm. Only talks can end the differences,” Mr. Chauhan had said on Thursday.
