GRA says ‘higher taxation’ claims baseless

first_imgThe Guyana Revenue Authority (GRA), responding on Friday to claims that higher taxation has led to the closure of BEV Enterprises’ shrimp processing facility, has said the accusations are baseless, since the Guyana Association of Trawler Owners and Seafood Operators continues to reap significant benefits.According to the GRA, as per an agreement signed between the Association and the Government since 2005, these benefits are being garnered.GRA has said the issue of higher taxation was raised by reports and letters published in the media, hence the tax body has sought to debunk the misleading claims. The GRA statement also indicated that the owners of BEV have refuted the allegations, and have noted that they have a “generous taxation” arrangement with the Government.Some of the soon-to-be- unemployed workers“It should be noted that GRA’s policy is to ensure that persons granted concessions act in accordance with the terms and conditions under which the tax exemptions were granted. As far as the GRA is aware, BEV Enterprises were utilising (their) concessions as per the agreement. Whilst recognising the rights of persons to pen letters voicing their opinions, the Authority hopes that opinions shared involving matters of taxation will be firmly grounded in facts, and not hearsay,” the GRA has said.With thousands of former sugar workers continuing to face challenges to find consistent employment, closure of the BEV processing facility will see over 390 employees being without employment. According to reports which surfaced on Tuesday, over 100 of the workers could be absorbed into other seafood operations, but many of BEV staff remain unsure as to how such an arrangement would be executed.The majority of the workers are women, and they are worried for their future as well as those of their children. Sources told this publication that proprietor and head of BEV Processors Inc, Bruce Vieira, held a recent meeting with staff, wherein he assured workers that they would receive benefits for their years of service.They were also informed that operations would cease by July 15, and the reactions were varied, ranging from sheer shock to passivity.Vieira was quoted in other sections of the media as saying he is hoping that Noble House Seafoods would purchase BEV’s plant and garner shrimp suppliers, which can provide employment. Vieira denied that his decision to leave the industry was due to a deal he has with an oil company which needs a sea front property.Union representationFollowing cries from some of the workers about the lack of representation by their union, the Guyana Agricultural and General Workers Union (GAWU) officials met with the management of BEV Enterprises on Thursday, when the company agreed to pay the workers a series of incentives.According to the Union, the news of the company closing operations came as a shock to many workers, most of whom are single mothers already finding it challenging to solely maintain their families.During Thursday’s meeting, the company’s owner indicated that several factors would have impacted the decision to end operations in the fishing industry. For the past 34 years, the company, located at Houston, Greater Georgetown, has been one of the leading processors of fish and shrimp for local and foreign markets.The company has agreed to pay its workers some incentives to soften the impact that the closure will have on their livelihoods. Apart from the statutorily required redundancy payments, the company, through the union/company engagement, has agreed to pay workers for their full year’s annual leave. This would be done even though the year’s service would be incomplete when operations cease.Additionally, the workers are expected to receive their full incentive payment for July 2018, although the company would end operations around July 15, 2018.last_img read more

7% of U.S. Consumers “Very Likely” to Buy an iPad

first_imgWhat it Takes to Build a Highly Secure FinTech … Related Posts Why IoT Apps are Eating Device Interfaces The Rise and Rise of Mobile Payment Technology About half of all iPad owners read newspapers on their tablets and more than a third read magazines. For other e-readers, these numbers hover slightly above 10%. This low number doesn’t come as a surprise, as these devices were clearly designed as e-book readers and don’t offer a convenient way to read newspapers on the Web. Even on these devices, however, the number of people who use them to read newspaper and magazines has almost doubled in the last few months. frederic lardinois Tags:#Apple#mobile#Statistics#web Role of Mobile App Analytics In-App Engagement According to ChangeWave, iPad owners mostly use their devices to surf the Web (83%), check email (71%) and use apps from the app store (56%). About a third of iPad owners use their tablets to read e-books. According to some analysts, Apple is now selling more iPads than Macs. Judging from the latest survey data from ChangeWave Research, the demand for Apple’s tablets in the U.S. will only continue to grow. About 7% of all respondents to ChangeWave’s survey said that they were “very likely” to buy an iPad and another 13% said that they were “somewhat likely” to buy one. The large majority of iPad owners said that they were “very satisfied” with their purchase, though about 11% cited the lack of Flash-support as their biggest gripe against the iPad. Focus: E-Books, Newspaper and MagazinesAmong those respondents who already owned an e-reader, the Kindle is still the most popular device (62%). After just a few weeks on the market, however, the iPad already registered a 16% share in this survey, which puts it far ahead of the Sony Reader family and Barnes & Noble’s Nook.A lot has been written about how the advent of e-readers, the iPad and similar tablets will change the magazine and newspaper industry. While the exact extent of the iPad’s influence on these industries still isn’t clear, it’s worth noting that iPad owners are far more likely to use their tablets to read newspapers and magazines than those who own any other kind of e-reader. last_img read more

Return to Sender – HVAC Return Pathway Options

first_imgRELATED ARTICLESReturn-Air ProblemsThis New Door Design Solves an Old ProblemPerfect Balance Makes the CutNew Green Building Products — March 2011An Easy Retrofit for Return AirAll About Furnaces and Duct Systems If a forced-air HVAC system is pushing more air into a space or room than return pathways can match, some spaces in the home become pressurized and others depressurized. This imbalance can cause problems: thermal comfort, moisture, and even combustion safety.Types of HVAC returnsIn an ideal world, every supply would have a companion return duct. This approach is called a dedicated return for each supply. But most older and even many new homes have one or maybe two central returns located in common spaces because it is less expensive and difficult to locate and run just a supply to each space. With central returns, here are the ways to provide return pathways: door undercuts, jump ducts, transfer grilles, and the deKeiffer bypass.Door undercutsThis is certainly the easiest and cheapest way to attempt a return pathway but it is rarely sufficient. For most situations, door undercuts need to be greater than 1.5 inches to be sufficient and that amount of undercut is very often not acceptable for aesthetic or privacy reasons. Jump ductsA jump duct is a large insulated flex duct that connects two ceiling grilles, one just inside the door to the supplied room and the other just on the other side of the door in the hallway ceiling. The sharp bend and variegated surface of the interior lining of the jump duct reduces sound transfer without compromising air movement. Since this approach penetrates the ceiling plane, the jump duct must be carefully air sealed if it breaks into an unconditioned space like the attic.Transfer grillesThere are two types of transfer grilles, above-door and high-low offset. The above-door transfer grille simply has two grilles located above the door between the room and common space, one on each wall, with offset baffles to limit sound transmission.The high-low offset is located in an interior wall framing cavity adjacent to the door between the room and common space. One grille is located high on the wall on one side (usually the common space), the other low on the wall (in the room). The offset reduces sound transmission. Note that this interior framing cavity must be clean and without wiring penetrations (or seal these penetrations as you would if it were an exterior wall framing cavity).The de Keiffer bypassAn HVAC engineer from Boulder, CO, Rob deKeiffer of the Boulder Design Alliance, came up with an elegant return pathway: the deKeiffer Bypass. The door trim is spaced off of the wall on both sides enough to create around 23 square inches of free air space connecting the room and the common space. The framing cavity space above the door is sleeved with sheet metal to create a dedicated pathway connecting the two sides of the spaced-out door trim.Armand Magnelli’s (Livable Housing, Inc.) perspectiveAnother approach is to install a product that combines a metal sleeve with an interior baffle and grilles on both sides of the wall, such as the Tamarak Return Air Pathway (RAP). Or one of Halton’s transfer grilles (these more commercial in nature). These products purportedly provide better noise reduction with good air flow and are relatively easy to install. The fit between standard stud spacing in interior partition walls. For an independent analysis of several approaches see the following review by the Building America Program.An advantage of using the products from Tamarak is that they are sized for CFM capacity, an important variable in balancing the airflow between rooms. The issue with the products from Tamarak and Halton is that while they provide an attractive and effective packaged solution it may be difficult to convince local HVAC distributors to stock their lines of products forcing contractors to order them online. Some of the other solutions are fabricated from stock components available at most HVAC distributors.The use of any of these solutions may also improve performance of whole house ventilation systems by enabling better circulation of fresh air from bedrooms at night, a crucial time to deliver fresh air to occupants.Your perspectiveBe great to learn what method you use and why?

Social Networking For Authors & Overcoming The Rejection Slip

first_imgNot a Novel IdeaThere are many other social networks for writers on the Web. So getting new users is going to be nearly as much of a challenge for Moysidis as getting a publisher to notice her debut novel.But according to Moysidis, most of the existing social networks for authors are geared towards helping writers self-publish. Writer’s Bloq is all about helping new writers get the attention of publishing houses. Which begs the question: how will Writer’s Bloq attract publishing industry people to the network?Moysidis replied that Writer’s Bloq is starting out with a focus on writers, but it intends to open up to publishers officially at a later date. In the meantime, she said that industry professionals are already registering… as writers. Many in the industry are budding writers themselves.Like any new social network, Writer’s Bloq has a very tough road ahead of it. The key is to get network effects going, in other words get more and more writers – and ideally publishing industry people too – signed up and using the site regularly. Easier said than done. But Writer’s Bloq has a great design, enthusiastic early users and a Kickstarter project (see video below) to raise money for offline meetups – cleverly called “bloqparties.”Perhaps most importantly, Writer’s Bloq has a passionate, focused founder in Nayia Moysidis. Whose ultimate goal, by the way, is still to get her first novel published. The first thing that struck me about Writer’s Bloq when I signed up for a nosey, was the crisp and clean design. Goodreads could learn a thing or two from that.Writer’s Bloq has two main sections: a writing section and a reading section. As with any social network, it’s advisable to have a look around first before posting your own content. There are many ways you can discover the writing of others – by genre, format, status (published or unpublished), or tags.You can choose to read a piece immediately, or save it for later. You can also send it to your Kindle. The staples of social networks are all there: comments, likes, sharing via Facebook and Twitter, the option to subscribe to the author. What’s In It For WritersWriter’s Bloq is clearly very early in its evolution – there isn’t a huge amount of activity on the site right now. That is of course the problem every new social network has. Goodreads is at the opposite end of the social network spectrum. It’s a mature social network that reached its tipping point a few years ago and is now in the midst of mainstreaming (10 million users and counting!).So the challenge for Writer’s Bloq is to get its core user base – budding writers and people in the publishing industry – to sign up. I asked Nayia Moysidis why new writers should post their work on Writer’s Bloq. Why not just self-publish, if they aren’t able to land a traditional publisher? She replied that when writers submit a manuscript to a publisher, essentially they are after the following three things:Editing and serious feedback on their work.Marketing.Validation.Writers can’t get those things by self-publishing, said Moysidis. The aim of Writer’s Bloq is to give writers a better opportunity to attract publishers. They can promote their work on Writer’s Bloq and get feedback from peers – and perhaps even from publishers sniffing around the site. The community helps self-select the best writing, through ratings and comments. 4 Keys to a Kid-Safe App richard macmanus Yesterday I reviewed the leading social network for book readers, Goodreads. In the second post in my Social Books series, I’m checking out a brand new social network for book writers. Called Writer’s Bloq, it was founded by a young wannabe writer from New York named Nayia Moysidis. In a phone interview, I discovered that Moysidis, a graduate of Columbia University’s creative writing program, started Writer’s Bloq because of the frustrations she encountered trying to get her first novel noticed by publishers. She’d sent 93 individualized letters to publishing houses, but only received a few generic rejection letters in response.Like many entrepreneurs, Moysidis is a very determined person. After being largely ignored by publishers, her next step was to take an intern job at Simon & Schuster. There she was dismayed to find her very own novel – submitted under a pen name – in the slush pile! On the plus side, Moysidis saw first hand that it was impossible for a publishing house like Simon & Schuster to pick up every book sent to them. They simply receive too many manuscripts.After seeing the writer submission process from the other side, Moysidis concluded that publishers are so overwhelmed that they aren’t discovering enough new talent. She felt that writers needed a better way to try and get noticed, which ultimately would help publishers too. So she created Writer’s Bloq, a wonderfully named social network where writers can post snippets of their work and network with others in the industry.

Revoking of Article 370 | Move triggers fears in the northeastern region

first_imgThe Centre’s move to revoke Article 370 has triggered apprehensions in the northeastern States enjoying similar constitutional safeguards. The Constitution bestows special provisions under Article 371A for Nagaland, Article 371B for Assam, Article 371C for Manipur, Article 371F for Sikkim and Article 371F for Mizoram.Former Mizoram Chief Minister Lal Thanhawla said the move by the BJP-led National Democratic Alliance was a “red alert” for the people of the northeast.“It has become a threat to States like Mizoram, Nagaland and Arunachal which are protected by the Constitution. If 35A and 370 are repealed, Article 371G safeguarding the interests and existence of lesser tribals of Mizoram will be under severe threat,” he said.Also Read A snapshot of Article 371  The Mizo National Front government chose to adopt a “wait and watch” policy but NGOs such as the influential Young Mizo Association — which has spearheaded a movement against the Centre’s bid to push the Citizenship (Amendment) Bill — said any move to “tamper with” Article 371G would be opposed to the hilt.The Neiphiu Rio-led coalition government in Nagaland, in which BJP is a partner, chose not to react. Neither did the Naga Students’ Federation.‘Minorities undermined’“This is something undermining the minorities in India. I think this is very undemocratic. People in Nagaland would be particularly worried as a settlement of the Naga political process is long overdue,” said Chuba Ozukum, president of Naga Hoho, apex body of all Naga tribes. The “political process” is a term used for the peace talks between New Delhi and the Isak-Muivah faction of the extremist National Socialist Council of Nagaland that fought a secessionist battle with the armed forces until declaring a truce in July 1997.last_img read more

Labour Ministry Looking to Expand School Days Count Campaign

first_img The Ministry of Labour and Social Security is looking to expand its ‘School Days Count’ campaign to reach more institutions where there are high rates of non-compliance with the 85 per cent attendance requirement under the Programme of Advancement Through Health and Education (PATH).The initiative was launched in February 2018 as part of efforts to address attitudes to school attendance and punctuality among students who are PATH beneficiaries.Portfolio Minister, Hon. Shahine Robinson, said that the first phase of the campaign was implemented in the 13 worst-affected institutions.“As an incentive, 10 scholarships, each valued at $250,000, will be awarded to PATH students who have achieved 100 per cent attendance rates,” she noted.She was speaking at a quarterly press briefing held at the Ministry’s North Street Offices today (September 4).Meanwhile, the Ministry continues to provide opportunities for young people under PATH to achieve their goals.To this end, two additional students have been presented with scholarships under PATH’s 15th anniversary tertiary award programme.They were Brittany Munroe, who received $400,000 to continue studies towards a Bachelor’s degree in Pharmacology at the University of Technology; and Shanique Davidson, who received $600,000 towards the attainment of a Bachelor’s Degree in Medicine and Surgery at the University of the West Indies.In celebration of its 15th anniversary, 17 beneficiaries of PATH were awarded scholarships valued at $15 million last year, to pursue studies at the tertiary level. The initiative was launched in February 2018 as part of efforts to address attitudes to school attendance and punctuality among students who are PATH beneficiaries.

Researchers find no link between allergy friendly dogs and lower risk of

first_img Source: Reviewed by James Ives, M.Psych. (Editor)Nov 15 2018Growing up with dogs is linked to a lower risk of asthma, especially if the dogs are female, a new study from Karolinska Institutet and Uppsala University in Sweden shows. However, the researchers found no relation between ‘allergy friendly’ breeds and a lower risk of asthma. The study is published in the journal Scientific Reports.Earlier studies have demonstrated a link between growing up with dogs and a lower risk of childhood asthma, but it has not been known whether this association is modified by dog characteristics. In this new study, the researchers have interrogated how variables such as sex, breed, number of dogs or size of dog are associated with the risk of asthma and allergy amongst children raised in a home with a dog during their first year of life.”The sex of the dog can affect the amount of allergens released, and we know that uncastrated male dogs express more of a particular allergen than castrated dogs and female dogs,” says Tove Fall, Senior Lecturer at the Department of Medical Sciences – Molecular Epidemiology at Uppsala University, who led the study with Professor Catarina Almqvist Malmros at Karolinska Institutet. “Moreover, some breeds are described anecdotally as ‘hypoallergenic’ or ‘allergy friendly’ and are said to be more suitable for people with allergies, but there is no scientific evidence for this.”Classified by different traitsThe study included all children born in Sweden from 1 January 2001 to 31 December 2004 who had a dog in their home for the first year of life (23,600 individuals). Data from the Swedish population and health data registries were linked anonymously to two dog-owner registries from the Swedish Board of Agriculture and the Swedish Kennel Club. The dogs were classified by sex, breed, number, size and alleged ‘hypoallergenicity’.Related StoriesStudy examines differences in genetic risk factors for childhood-onset and adult-onset asthmaChaos in the house and asthma in children – the connectionWorld Asthma Day: How climate change is increasing cases of asthmaThe researchers then studied the relationship between the dogs’ characteristics and the risk of asthma and allergy diagnosis or the prescription of asthma or allergy drugs at the age of six. The statistical analyses controlled for all known confounders that could affect the risk of developing asthma or allergies, such as parental asthma/allergy, geographical location and number of siblings.Their results showed that the prevalence of asthma at age six was 5.4 per cent. Children with only female dogs at home had a 16 per cent lower risk of asthma than those raised with male dogs. However, living with a male dog did not correlate with a higher risk than living with no dog at all. Children living with two or more dogs had a 21 per cent lower risk of asthma than those who only lived with one dog.Hypoallergenic dogs linked to higher risk of allergyChildren of parents with asthma/allergies more often had breeds described as ‘hypoallergenic’ than children of parents without asthma/allergies – 11.7 per cent versus 7.6 per cent. Exposure to these breeds was associated with a 27 per cent higher risk of allergy but no increased risk of asthma.”The likely explanation for this higher risk is that families with a history of allergy to furred pets more often choose these dogs, and also that ‘allergy friendly’ dogs do not in fact release less allergens,” says Catarina Almqvist Malmros, Professor at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet and Consultant at Astrid Lindgren Children’s Hospital.”The finding should be treated with caution as we can say nothing about any actual causality,” she continues. “More studies are needed to monitor differences over time, measure the risk of allergies using biomarkers, and take account of the microflora.”last_img read more

New screening tool more likely to identify sexual and labor exploitation of

first_imgReviewed by James Ives, M.Psych. (Editor)Feb 20 2019A screening tool designed specifically to assess for human trafficking was more likely to identify sexual and labor exploitation of youth, as well as the risk factors, than a commonly used psychosocial assessment, reported researchers from The University of Texas Health Science Center at Houston (UTHealth) and Baylor College of Medicine.Participants for the study were recruited from Covenant House Texas, the largest shelter in Houston for homeless youth and young adults. Results were recently published in the International Journal of Environmental Research and Public Health.”The new assessment tool was much more effective at finding exploitation. It is important for providers working with high-risk groups to add these questions specific to trafficking,” said corresponding author Diane M. Santa Maria, DrPH, RN, dean ad interim and Dorothy T. Nicholson Distinguished Professor at Cizik School of Nursing at UTHealth. “Identifying them allows these youth to access services that they otherwise wouldn’t receive. You can’t help someone you don’t know about.”According to the United Nations Office on Drugs and Crime, Texas has the second-highest number of cases of human trafficking after California. A 2016 report by the Statewide Human Trafficking Mapping Project of Texas, estimated that 313,000 people were experiencing human trafficking, including 79,000 minors and youth experiencing sex trafficking.”An important part of this project was to have a screening process in place at Covenant House going forward to benefit the residents,” said first author Salina Mostajabian, MD, an adolescent medicine fellow in the Department of Pediatrics at Baylor when the study was conducted. “Having a standard tool will maximize the likelihood of identifying victims and getting them the needed resources.”Covenant House Texas offers onsite psychiatry and psychology services provided by Baylor and employs a full-time mental health counselor and other mental health and trauma-informed care services to help meet the needs of these youth.”This study emphasizes the need for health care providers to recognize how difficult it can be for youth who have been trafficked to open up to providers,” said co-author Claire Bocchini, MD, assistant professor of pediatrics at Baylor and faculty member of the Texas Children’s Hospital Center for Child Health Policy and Advocacy. “Providers need to be trained on the importance of using a trafficking-specific screening tool to maximize the opportunity to identify trafficking survivors. We also have to offer the most supportive and accepting atmosphere as possible to help overcome mistrust in the health care system and optimize acceptance of resources.”Bocchini, who has helped develop curricula on human trafficking for health care providers, and Mostajabian conducted focus groups with youth who completed the screening tool. Those sessions provided insight into the barriers that youth experience in being identified as victims, as well as in accessing services that could help them find safety and treatment. Youth reported mistrust of the system, fear of involving law enforcement, not wanting to interact with the mental health system, and stigma as barriers to disclosure.”Identifying trafficking victims is a challenging process, due to many factors including extreme trauma and mistrust. This new screening tool will allow health care and social services providers to quickly identify and provide life-changing services to homeless young adults who have been victims of labor and sex trafficking,” said Leslie Bourne, executive director of Covenant House Texas.Groups identified as most at risk for trafficking include youth involved in the foster care or juvenile justice systems, those who experienced abuse, youth who run away from home, and those who are unstably housed or homeless.”There is a pipeline from foster care and juvenile justice to homelessness, especially in Houston,” said Santa Maria, who holds the John P. McGovern Distinguished Professorship in Nursing at UTHealth.The study, which included 121 shelter residents ages 18-21, reported that 44 percent of youth in the study had been arrested at some point, with a third of those arrested as a child; 35 percent had a history of foster care; 71 percent had been kicked out of their homes; and 45 percent had run away from home. Of those who had run away, 65 percent cited abuse as the reason. Of those abused, 71 percent reported physical abuse; 80 percent reported emotional or verbal abuse; and 14 percent reported sexual abuse.The sex trafficking screening tool asked specific questions about trade for sex based on the data, 22 percent reported they had traded sex for food, clothing, money, shelter, favors, or other necessities for survival. Of those, 70 percent were minors (under age 18) the first time they traded sex. Commercial sexual exploitation was more likely to be identified by the new tool than the standard psychosocial assessment.Related StoriesResearch on cannabis use in women limited, finds new studyComplement system shown to remove dead cells in retinitis pigmentosa, contradicting previous researchResearch sheds light on sun-induced DNA damage and repair”We found that the entry into trafficking also happens through family, friends, and acquaintances. This was extremely eye-opening and needs to be explored,” Santa Maria said. “These are kids who have fallen through every crack society has. When these youth are in desperate need of food and shelter, the vulnerability for trafficking is tremendous.”Sexual history details from medical reports revealed that 19 percent reported more than 10 sexual partners in their lifetime, 29 percent had a prior history of a sexually transmitted infection, 2 percent were HIV-positive, and only 64 percent reported any condom use.”There’s difficulty in untangling what’s happening. Is it sexual abuse, or sexual abuse and human trafficking? We want providers to be asking the right questions,” Santa Maria said.The study also uncovered a link between homelessness and mental health issues in youth. According to the results, 53 percent had a recorded psychiatric diagnosis and more than half of those had more than one diagnosis. Half (49 percent) of the psychiatric diagnoses were for depression, over half (59 percent) had a history of psychiatric hospitalization, and more than a third (42 percent) had at least one suicide attempt. More than half of all the participants, 54 percent, had used cannabis or synthetic cannabis; and 17 percent had polysubstance abuse in the past.Half of the participants in the study had stayed on the streets in the past month; 29 percent had been in treatment centers, shelters, or detention facilities; and 19 percent reported spending most nights in parks, tents, cars, or abandoned buildings.”These youth are very resilient survivors,” said Santa Maria, whose research has focused heavily on youth and young adults experiencing homelessness. “We want providers to identify young people and then we need a coordinated response to meet their mental health, health care, and social services needs so they can move forward.”Study co-author Elizabeth Newlin, MD, vice chair for child and adolescent psychiatry at McGovern Medical School at UTHealth, and her team are treating youth who have experienced sex trafficking. She envisions a comprehensive system designed to treat youth that includes collaborative efforts among law enforcement, the juvenile court system, community-based nonprofit organizations, and the addition of a designated unit at UTHealth Harris County Psychiatric Center (UTHealth HCPC).A proposal was submitted to the Texas Legislature for funding that would include a designated in-patient unit, as well as community, school, and home-based intensive outpatient services through the Trauma and Resilience Center in the Department of Psychiatry and Behavioral Sciences at McGovern Medical School. The proposal includes research to provide a best-practices model that could be disseminated to the rest of the state. The interdisciplinary treatment team at the center includes specialists from child psychiatry, adolescent medicine, nursing, psychology, and social work. The Trauma and Resilience Center’s multidisciplinary teams would work in coordination with existing specialized programs that provide case management and advocacy for child sex trafficking survivors.”Child sex trafficking survivors have often been involved in multiple systems including CPS-affiliated group or foster homes and shelters, and juvenile justice. Often these kids feel like they do not have real options for receiving meaningful treatment. They are just trying to survive and recovery seems completely out of reach,” said Newlin, associate executive director of the Trauma and Resilience Center and chief of child and adolescent services at UTHealth HCPC. “We could meet their most acute needs, get a better handle on the best next step for that child, and with a continuum available, provide a source of constancy and security as they pursue a full recovery from trauma.”Connie Wiemann, PhD, director of research for the Section of Adolescent Medicine in the Department of Pediatrics at Baylor College of Medicine, also contributed to this project.Mostajabian was principal investigator on a grant from Texas Pediatric Society Foundation that helped fund the study. She is currently a practicing adolescent medicine physician at a nonprofit adolescent health clinic in Austin. Source: read more

BioSA team aims to develop improved bone regeneration scaffold design

first_imgReviewed by James Ives, M.Psych. (Editor)Jul 2 2019Millions of patients all over the world undergo surgical procedures related to bone defect repair every year. With an ever-increasing life expectancy and the issues that come with a decaying skeleton, the number of interventions can only increase in the coming years. This is why orthopedic surgeons are constantly looking for improved medical implants for the treatment of bone repair.Following certain surgeries and traumatic experiences, like traffic accidents, patients often suffer from significant fractures and losses to the bone, referred to as bone defects. Bone scaffolds are porous implants that are used in order to fill significantly large defects. While the currently available solutions are suitable when implanted in non-load bearing areas, like the face, using a stronger material could result in a more attractive option when filling defects in load-bearing areas, like the bones found in legs.Related StoriesFeeling safe and good sleep at night matter most to sick kids in hospitalCommon antibacterial agent may be bad news for bone healthPenn Medicine and Grand View Health partner to provide advanced orthopedic careThe University of Malta has teamed up with Mater Dei Hospital to address the shortcomings of current bone scaffolds on the market in a project entitled Biodegradable Iron for Orthopaedic Scaffold Applications – BioSA. The project is being led by Prof. Ing. Joseph Buhagiar, from the Department of Metallurgy and Materials Engineering, and also involves members from the surgical team at the Department of Orthopaedic, Trauma and Sports Medicine at Mater Dei Hospital under the coordination of Mr Ray Gatt M.D., as well as academics from various departments at the University of Malta. The team members are pooling their expertise to develop an improved bone regeneration scaffold design with optimized characteristics.Despite the fact that ceramic scaffolds are widely used, their tendency to break due to their brittle nature, has made them inadequate for use in bones that are subjected to sudden loading, while polymeric scaffolds lack the mechanical strength to be used in load-bearing applications. Metals, on the other hand, have the potential to exhibit the perfect balance between strength and toughness. The BioSA scaffold is being designed such that it corrodes at a controlled rate within the body, to match the rate at which the bone is healing. This aspect could result in reducing the necessity of a second surgical intervention to remove the implant after bone has healed.The BioSA team is focused on understanding the corrosion behavior of such an implant while also studying the effect that such an implant has on cells found in the bone. Through an innovative processing technique, based on the use of metal powders, the team also aims to gain control over the shape of the final scaffold. Accidents can happen to everyone and defects can be bigger than the body can heal naturally. So ideally scaffolds are not designed as one-size-fits-all but can also be custom-made for a specific patient. Source:University of Maltalast_img read more

Mystery of the cargo ships that sink when their cargo suddenly liquefies

first_imgThink of a dangerous cargo and toxic waste or explosives might come to mind. But granular cargoes such as crushed ore and mineral sands are responsible for the loss of numerous ships every year. On average, ten “solid bulk cargo” carriers have been lost at sea each year for the last decade. Credit: Shutterstock Solid bulk cargoes – defined as granular materials loaded directly into a ship’s hold – can suddenly turn from a solid state into a liquid state, a process known as liquefaction. And this can be disastrous for any ship carrying them – and their crew. In 2015, the 56,000-tonne bulk carrier Bulk Jupiter rapidly sunk around 300km south-west of Vietnam, with only one of its 19 crew surviving. This prompted warnings from the International Maritime Organisation about the possible liquefaction of the relatively new solid bulk cargo bauxite (an aluminium ore). A lot is known about the physics of the liquefaction of granular materials from geotechnical and earthquake engineering. The vigorous shaking of the earth causes pressure in the ground water to increase to such a level that the soil “liquefies.” Yet despite our understanding of this phenomenon, and the guidelines in place to prevent it occurring, it is still causing ships to sink and taking their crew with them.Solid bulk cargoesSolid bulk cargoes are typically “two-phase” materials as they contain water between the solid particles. When the particles can touch, the friction between them makes the material act like a solid (even though there is liquid present). But when the water pressure rises, these inter-particle forces reduce and the strength of the material decreases. When the friction is reduced to zero, the material acts like a liquid (even though the solid particles are still present).A solid bulk cargo that is apparently stable on the quayside can liquefy because pressures in the water between the particles build up as it is loaded onto the ship. This is especially likely if, as is common practice, the cargo is loaded with a conveyor belt from the quayside into the hold, which can involve a fall of significant height. The vibration and motion of the ship from the engine and the sea during the voyage can also increase the water pressure and lead to liquefaction of the cargo.

Water can also move from within the cargo to its surface as a result of liquefaction and subsequent sloshing of this free water can further impact the vessel’s stability. Unless the sloshing can be stopped, the ship is in danger of sinking.The International Maritime Organisation have codes governing how much moisture is allowed in solid bulk cargo in order to prevent liquefaction. So why does it still happen? The technical answer is that the existing guidance on stowing and shipping solid bulk cargoes is too simplistic. Liquefaction potential depends not just on how much moisture is in a bulk cargo but also other material characteristics, such as the particle size distribution, the ratio of the volume of solid particles to water and the relative density of the cargo, as well as the method of loading and the motions of the vessel during the voyage.The production and transport of new materials, such as bauxite, and increased processing of traditional ores before they are transported, means more cargo is being carried whose material behaviour is not well understood. This increases the risk of cargo liquefaction.Commercial agendas also play a role. For example, pressure to load vessels quickly leads to more hard loading even though it risks raising the water pressure in the cargoes. And pressure to deliver the same tonnage of cargo as was loaded may discourage the crew of the vessel draining cargoes during the voyage. What’s the solution?To tackle these problems, the shipping industry needs to better understand the material behaviour of solid bulk cargoes now being transported and prescribe appropriate testing. New technology could help. Sensors in a ship’s hold could monitor the water pressure of the bulk cargo. Or the surface of the cargo could be monitored, for example using lasers, to identify any changes in its position.The challenge is developing a technology that is cheap enough, quick to install and robust enough to survive loading and unloading of the cargo. If these challenges can be overcome, combining data on the water pressure and movement of the cargo with information on the weather and the ship’s movements could produce a real-time warning of whether the cargo was about to liquefy.The crew could then act to prevent the water pressure in the cargo rising too much, for example, by draining water from the cargo holds (to reduce water pressure) or changing course of the vessel to avoid particularly bad weather (to reduce ship motions). Or if that were not possible, they could evacuate the vessel. In this way, this phenomenon of solid bulk cargo liquefaction could be overcome, and fewer ships and crew would be lost at sea. Provided by The Conversationcenter_img When a solid bulk cargo liquefies, it can shift or slosh inside a ship’s hold, making the vessel less stable. A liquefied cargo can shift completely to one side of the hold. If it regains its strength and reverts to a solid state, the cargo will remain in the shifted position, causing the ship to permanently tilt or “list” in the water. The cargo can then liquefy again and shift further, increasing the angle of list. A cargo ship being loaded with bauxite.
