Um bate-papo ao cair da noite

 

Eu sabia que meu blog era diferente mas não sabia que existia uma denominação para esse tipo de postagem. Vim a descobrir quando o Blogger me avisou que a inserção automática de postagens no Google+ não era possível para o tipo “importação” que é o que pratico. Porém, as minhas postagens não são totalmente “importadas”, uma vez que tenho que selecionar os artigos mais atuais e interessantes, e na edição tenho que clicar uma média de 30 vezes até a formatação final. Dá um bocado de trabalho. Preciso ajustar as imagens, fazer um snapshot do logotipo do site e inserí-lo abaixo, e também de acordo com a política do Blogger, sou responsável pelas postagens que publico. Sendo assim, creio que pelo menos 30% do conteúdo delas são de minha autoria.

Portanto, não são totalmente “importadas”….e meu trabalho é prolífico, já estou caminhando para 2.500 postagens em 9 meses, somente no sid_melo_blogreen, graças ao Blogger.

Laboratory Analyzer

 

Mon, 10/27/2014 - 10:55am

 

Analytical Systems Keco has developed an analyzer that analytically quantifies H₂S in liquids such as crude oil, fuel oil, naphtha, water, marine diesel, gasoline and other liquids. The Sample Transfer Stripper (STS), ASI membrane technologies and ratiometric colorimetric technology are what gives the Model 205L the enhanced ability to quantify H₂S in liquids. Specific to H₂S with no cross-interference with other components, the typical analysis time is 15 to 25 mins with only one push button for analysis. The 205L is field-proven for reliability and precision with no field calibrations required. Quantitative analysis is in ppb, ppm and up to saturation levels. The STS acts as an ultra-effective filter, blocking any mists or liquid carry-overs. This reduces any maintenance requirements that plague analyzers from other manufacturers. The detection technology used in the 205L is based on chemically specific density changes. The advanced tape detector utilized in this analyzer is the only detection method proven to be specific only to H₂S, proven by thousands of worldwide applications.

Liquid Dispersion Unit

 

Wed, 10/29/2014 - 12:26pm

 

The new Mastersizer 3000 Hydro SV small volume liquid dispersion unit delivers reliable particle size measurement using just a few milligrams of sample. Particle size is a performance-defining parameter for many industrial products. The ability to measure small samples sizes becomes crucial when sample availability prevents the use of larger amounts of material. This is especially true during early stage product development, for example. By minimizing sample and dispersant use the Hydro SV also reduces the development, purchase and disposal costs associated with routine analysis.

Efficient sample dispersion ensures that the particle size data measured by a laser diffraction analyzer are both representative and relevant. Launching on the third anniversary of the Mastersizer 3000, the Hydro SV is a simple, easy to use wet dispersion accessory. It extends smarter particle sizing to small volume measurement by making it possible to both develop and apply wet dispersion using just 6 mL of sample. This enables reliable particle size information to be obtained in the earliest stages of product development, when material availability is often extremely limited, delivering the essential data required to understand and control product and process performance.

The Hydro SV has a unique cuvette design that enables representative sample measurement across a wide range of particle sizes. It has been developed with the same intense focus on ease of use that underpins every element of the Mastersizer 3000 and enables all users, even those primarily familiar with dry measurement, to access the benefits that wet dispersion offers. These include the ability to recover the sample following analysis. The results obtained using the Hydro SV are comparable with those obtained using the Mastersizer 3000’s larger-volume Hydro MV and Hydro LV wet dispersion accessories, supporting efficient method and specification transfer through product scale-up.

Nerve block procedure is safe in children, report researchers

 

---

A regional anesthesia procedure widely used for surgery in infants and young children is effective and safe, with a minimal rate of serious complications, concludes a large database study in the October issue of Anesthesia & Analgesia.

On analysis of more than 18,000 procedures, caudal nerve block in children has a complication rate of fewer than two percent, with little or no risk of long-term adverse effects, according to the report by Dr Santhanam Suresh and colleagues of Northwestern University, Chicago. But the study shows variation in the local anesthetic doses used for caudal block, raising concern about potential toxic effects.

Database Used to Assess Safety of Caudal Block in Children

In caudal block, a small dose of local anesthetic is injected into the base of the spine to numb feeling in the lower body. It is usually added to general anesthesia, with the aim of controlling pain after surgery while reducing the required dose of general anesthetic. Performed largely in infants, caudal block is "likely the most common regional anesthesia technique performed in children," the researchers write.

Dr Suresh and colleagues assessed safety outcomes in 18,650 children, average age 14 months, undergoing surgery with caudal block. The procedures were performed at 18 children's hospitals from 2007 to 2012. The study used data from the Pediatric Regional Anesthesia Network (PRAN) -- a centralized database collecting detailed information on practice patterns and complications of regional anesthesia techniques in children.

The overall estimated complication rate after caudal block was 1.9 percent. The risk of complications was somewhat higher in younger children. However, this was no longer significant after adjusting for the higher risk in awake children, compared to those under general anesthesia. There was no evidence that performing the procedure with ultrasound guidance reduced the risk of complications.

The most common complications were unsuccessful caudal block and complications related to incorrect needle placement. However, none of the reported complications led to lasting or permanent adverse effects. Serious complications such as cardiac arrest and seizure were rare, occurring in just 4 out of 18,650 children.

Large Variations in Anesthetic Dose

The study did find a large variation in the dose of local anesthetic used for caudal block. About one-fourth of children received a dose with the potential to cause toxic effects -- the use of such potentially toxic doses was higher in younger children.

Caudal block is a widely used regional anesthetic technique in infants and young children. Most previous studies have come from single hospitals, making it difficult to assess the risk of uncommon complications and adverse effects. The use of the cooperative PRAN database, combining data from many different hospitals, helps overcome this limitation.

The results support the safety of caudal block during surgery in children. The overall complication rate is low, while the risk of long-term adverse effects is very low. "The current study is, to the best of our knowledge, the largest study to demonstrate safety of a single regional anesthesia technique in children," Dr Suresh and coauthors write.

However, the results draw attention to variations in the local anesthetic doses used for caudal block, potentially increasing the risk of toxic effects. Further studies are needed to define the optimal local anesthetic dosage, as well as the pain-relieving effectiveness of caudal block for specific types of surgery.

"The PRAN database was a lot of work to create, but it is an important contribution to the safety of children undergoing anesthesia," comments Dr. Steven L. Shafer of Stanford University, Editor-in-Chief of Anesthesia & Analgesia. "This paper shows that caudal blocks for post-operative pain control are safe in children. It will help to guide physicians, and parents, in selecting the anesthetic that provides the best outcome for their kids."

Telephone Coaches Improve Children's Asthma Treatment

 

---

A novel program at Washington University School of Medicine suggests that peer trainers who coach parents over the phone on managing their children’s asthma can sharply reduce the number of days the kids experience symptoms. The program also dramatically decreased ER visits and hospitalizations among low-income children with Medicaid insurance.

Managing childhood asthma is difficult. Rather than giving daily medications -- even when children feel well -- many parents treat asthma only when symptoms become severe. This practice can lead to missed school days, trips to the ER and hospitalizations.

But a novel program at Washington University School of Medicine in St. Louis suggests that peer trainers who coach parents over the phone on managing their children's asthma can sharply reduce the number of days the kids experience symptoms. The program also dramatically decreased ER visits and hospitalizations among low-income children with Medicaid insurance.

"We tried a new approach for managing asthma, and it worked," said the study's first author Jane Garbutt, MD, a professor of medicine. "Peer trainers -- moms of kids who had asthma -- provided education and support to parents to enhance care provided by primary care physicians. This additional support helped parents to better manage their child's asthma."

The results of the study are available online in The Journal of Allergy and Clinical Immunology.

Asthma is the most common chronic disease among children. On average, one in 10 children in the United States has asthma. The condition is more common in urban, low-income areas. In the city of St. Louis, one in five children has asthma.

The annual cost of treating asthma in the United States is almost $18 billion, according to the Asthma and Allergy Foundation of America. Garbutt estimated that every dollar spent on this new program for children with Medicaid insurance could save $3 by preventing ER visits and hospitalizations.

Garbutt The two-year trial evaluated 948 families with children ages 3 to 12 years who had asthma. The families, recruited from 22 pediatric practices, were divided randomly into two groups. In one group, families received usual asthma care from their pediatricians. Families in the other group also received usual asthma care in addition to regular calls from peer trainers over a one-year time frame. On average, each family received 18 calls.

During a series of brief calls, the peer trainers taught parents new skills such as how to give medications effectively, encouraged parents to take their children to primary care physician appointments and provided support to help parents better manage their children's asthma. Parents chose a topic for each conversation, which lasted 10 minutes on average.

After one year of telephone coaching, families in the peer training group reported on average that their children experienced an additional three weeks without asthma symptoms, compared with children in the other group. Children with Medicaid insurance showed a similar reduction in asthma symptoms and had 42 percent fewer ER visits and 62 percent fewer hospitalizations. These reductions lasted through a year of follow- up without any further contact with the peer trainers.

Garbutt said the researchers found out that most parents weren't aware if their children were having asthma symptoms. The study motivated many parents to start a notebook of daily symptoms, talk to their children's teachers and treat their children's asthma daily, as opposed to waiting until symptoms were severe.

"Asthma can cause significant problems for children and their families," said Robert Strunk, MD, professor of pediatrics and the paper's senior author. "The peer-training approach makes so much sense because it can help parents overcome barriers that prevent effective use of medications and other issues that interfere with asthma care. Seeing the outcomes of Dr. Garbutt's study has been gratifying, and I hope that her peer training model can be applied broadly.

Garbutt's goal is to see this model adopted by hospitals or insurance companies. "This is an exciting new approach to chronic disease management, and we would like for it to reach many families," she said. "If implemented on a large scale, I think a program like this can help children with asthma live full, healthy lives."

Mapping future of adolescent substance use treatment

 

---

Adolescent substance use treatment is at a critical turning point -- treatment success is short-lived and the field lacks a definitive best approach. Researchers from the University of Pittsburgh conducted a comprehensive literature review to identify the common traits underlying different therapies aimed at reducing substance use and then recommend future directions. Their findings are available as part of an adolescent-focused special issue from Substance Abuse, the official journal of Association for Medical Education and Research in Substance Abuse (AMERSA) and a publication from Routledge.

"Psychotherapy research has shifted," co-author Dr. Tammy Chung mentioned, "from comparing outcomes across different types of treatment to determining 'how' and 'for whom' an intervention works." In keeping with this new approach, the review at hand focused on studies concerning mechanisms of change for various "brands" of psychotherapy and distilled important implications for treating adolescent substance users. "Our critical review on the limited existing treatment mechanism studies," explained co-author Dr. Jessica Black, "found that 'common' processes, such as positive social support, rather than a particular treatment modality, account for positive adolescent substance use outcomes."

As for the future of adolescent substance use treatment, Drs. Chung & Black describe a need to focus on the "active ingredients" of therapies and their respective "targets." In addition, practitioners need to gain a better handle on the interaction between these aspects of specific therapies, overarching "common processes" like positive social support, and patients' lives outside of treatment.

In A Flood, This Amphibious House Starts To Float

 

Instead of building houses on stilts, it might make more sense to just build houses that turn into boats.

Thanks to climate change, some of the world's rainiest places are likely to get rainier—and more likely to flood. In the U.K., where intense rainfall led to floods that caused over $1.5 billion in damages last year, architects have come up with an answer: An amphibious house that starts to float when water levels rise.

Built on a small island in the Thames River, the house was designed to replace a family home originally built on stilts. Because of rising flood levels, the house wasn't high enough—but because it happened to be in a conservation area with special regulations, it wasn't possible to build something taller. Getting permits for a floating house wasn't possible, either. Instead, the architects found a solution in the middle.

The three-story house, made from lightweight timber, sits on a floating concrete hull. When the river floods, the house is designed to rise up in its dock, held in place by guideposts at each side. Here's a clip of it in action:

Construction finished this month, just in time for another season of heavy rains.

The house wasn't easy to build. Ironically, part of the problem was the terrible weather.

"Water is by far the biggest enemy of the construction industry," says Ruth Deans from Baca Architects, the firm that designed the house. "Inclement weather often slows down building work, but in our case as the U.K. experience one of its worst winters in memory, it completely halted all progress."

Building an amphibious house—especially on an island, where everything has to be transported by boat—was also difficult. "It was by far the hardest site our firm has ever faced," Deans says. "As the house weighs the equivalent of 170 cars, lifting it was a particularly unique challenge."

The amphibious design is about 25% more expensive than building a house with a normal foundation. Still, the architects argue that it's a reasonable solution for more houses in floodplains, and maybe even entire communities.

"Amphibious construction to date has only been used in small buildings, but it has the potential to overcome flood risk on a much larger scale by creating whole floating platforms, or even floating villages and towns," says Deans. "This could provide a cost effective solution to regenerating or preserving important sites where relocating residents and communities would have dire social and economic consequences."

But should we be rebuilding houses on flood-prone places at all? For Baca Architects, which has used different waterproofing techniques to design for places like the Netherlands and New Orleans, the answer seems to be yes. The firm recently wrote a new book illustrating their theories on how buildings and cities can be designed to live with water.
