Harvard University researchers have developed a new printing method that uses soundwaves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique could enable the manufacture of many new biopharmaceuticals, cosmetics, and food, and expand the possibilities of optical and conductive materials.“By harnessing acoustic forces, we have created a new technology that enables myriad materials to be printed in a drop-on-demand manner,” said Jennifer Lewis, the Hansjorg Wyss Professor of Biologically Inspired Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences and the senior author of the paper. Lewis is also a core faculty member at the Wyss Institute for Biologically Inspired Engineering and the Jianming Yu Professor of Arts and Sciences at Harvard.The research is published in Science Advances. Liquid droplets are used in many applications, from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used to pattern liquid droplets, but it’s only suitable for liquids that are roughly 10 times more viscous than water. Yet many fluids of interest to researchers are far more viscous. For example, biopolymer and cell-laden solutions, which are vital for biopharmaceuticals and bioprinting, are at least 100 times more viscous than water. Some sugar-based biopolymers could be as viscous as honey, which is 25,000 times more viscous than water.The viscosity of these fluids also changes dramatically with temperature and composition, making it ever more difficult to optimize printing parameters to control droplet sizes.,“Our goal was to take viscosity out of the picture by developing a printing system that is independent from the material properties of the fluid,” said Daniele Foresti, first author of the paper, the Branco Weiss Fellow, and research associate in materials science and mechanical engineering at SEAS and the Wyss Institute.To do that, the researchers turned to acoustic waves.Thanks to gravity, any liquid can drip — from water coming out of a faucet to the century-long pitch drop experiment. With gravity alone, droplet size remains large and drop rate difficult to control. Pitch, which has a viscosity roughly 200 billion times that of water, forms a single drop per decade.To enhance drop formation, the research team relies on generating sound waves. These pressure waves typically have been used to defy gravity, as in the case of acoustic levitation. Now, the researchers are using them to assist gravity, dubbing the new technique acoustophoretic printing.The researchers built a subwavelength acoustic resonator that can generate a highly confined acoustic field resulting in a pulling force exceeding 100 times the normal gravitation forces (1 G) at the tip of the printer nozzle — that’s more than four times the gravitational force on the surface of the sun.This controllable force pulls each droplet off of the nozzle when it reaches a specific size and ejects it toward the printing target. The higher the amplitude of the soundwaves, the smaller the droplet size, irrespective of the viscosity of the fluid.,“The idea is to generate an acoustic field that literally detaches tiny droplets from the nozzle, much like picking apples from a tree,” said Foresti.The researchers tested the process on a wide range of materials, from honey to stem-cell inks, biopolymers, optical resins, and even liquid metals. Importantly, sound waves don’t travel through the droplet, making the method safe to use even with sensitive biological cargo, such as living cells or proteins.“Our technology should have immediate impact on the pharmaceutical industry,” said Lewis. “However, we believe that this will become an important platform for multiple industries.”“This is an exquisite and impactful example of the breadth and reach of collaborative research,” said Dan Finotello, director of the National Science Foundation’s Materials Research Science and Engineering Centers (MRSEC) program. “The authors have developed a new printing platform using acoustic forces, which, unlike in other methods, are material-independent and thus offer tremendous printing versatility. The application space is limitless.”This research was co-authored by Katharina Kroll, Robert Amissah, Francesco Sillani, Kimberly Homan and Dimos Poulikakos. The Harvard Office of Technology Development has protected the intellectual property relating to this project and is exploring commercialization opportunities.,The research was funded by Society in Science through the Branco Weiss Fellowship and the National Science Foundation through Harvard MRSEC.

By Dialogo March 31, 2011 Seized material is of Ecuadorian and Bolivian craftsmanship and origin, this should call the attention of the international community, since explosives are of Bolivian origin in another country that is part of ALBA, whatâ€™s the deal, if they really are for guerrilla groups we are seeing that Bolivia is internationalizing its operations; that this country now not only is involved in drug trafficking as a government but it is clear that they support armed groups who have brought pain and mourning to Colombia, apparently after their actions in northern Peru a few years ago, now you can see their actions in Ecuador with military support (dynamite), congratulations to the authorities of the country trying to dismantle something that is causing violence to humanity, terrorism is a crime against humanity, and I think everyone knows that the Morales government is made up of ex – terrorists, one of them is his Vice President, next the Minister of Health who is the wife of a Tupamaro, Carlos NuÃ±ez former ELN, Chavez of the MRTA, in fact the list is long, hopefully this is a wake up call for the international agencies to combat terrorism now. Your information is good and keep moving forward. Ecuador has seized around 27,000 sticks of dynamite, as well as safety fuses and blasting caps, suspected to have been intended for Colombian irregular groups, the Ecuadorean police announced on 28 March. “27,000 sticks of dynamite, 27,500 meters of safety fuse, and 27,500 blasting caps were found,” said police officer Diego Chalén, an explosives expert with the Intervention and Rescue Group (GIR), in statements made public by the Ecuavisa television network. An agent from the police Anti-Organized Crime Unit (Ulco), for his part, stated that the items seized were homemade and of Ecuadorean and Bolivian origin, and that “their final destination is believed to have been irregular groups” in Colombia. The operation, in which three individuals were detained, took place in the Andean province of Azuay (in southern Ecuador) on 27 March, when the explosives were being transported by truck to the port of Guayaquil (in southwestern Ecuador), according to the police.
The defeat of two prominent Shining Path leaders on August 11 shows the strategic consequences and great importance in the dynamics of challenges towards national security that Peru faces. In this sense, the generalized criticism about the lack of leadership of the Peruvian government in the field of security, Shining Path’s control of coca areas in the VRAEM, as well as the deterioration of conditions for the continuity of operations and new investments in the areas of energy, mining, and oil in Sierra Sur, will face a new and challenging scenario. The continuity of businesses, operations and infrastructure projects in the VRAEM has an important space to aim its security standards and protocols in a scenario where “cohabiting” with Shining Path in their own terms is not a viable option. Shining Path in the VRAEM has not yet been defeated, but it has been seriously wounded. This makes it necessary to consider two immediate aspects: 1) Will the Shining Path be capable of perpetrating an act of armed violence in the short term with international media repercussion? If so, when, where, and how? Special attention is needed on transnational company operations in the fields of energy, oil and mining in the area. 2) Will a different Shining Path leadership emerge for the control or drug trafficking areas in the VRAEM, like when Artemio was defeated in the Huallaga? In this respect, there must be special attention on coca leaf grower organizations and illegal operators in the area. For Shining Path, the loss of three senior leaders of its armed groups is a strategic blow that limits its communication and mobilization capabilities to control drug trafficking, conduct armed actions and extort companies that operate in the area, control self-defense committees, farming families and local politicians. In regards to government measures, the operations conducted by the Armed Forces Joint Command (CCFFAA) are proof of the development of major intelligence capabilities and special operations to perform precise actions against the Shining Path’s leadership, which is being given space to recover their initiative after thirteen years in which this guerrilla group had the opportunity to regain their military capacity and control the VRAEM areas with little difficulty. Shining Path will have to speed up its pace, which makes it dangerous and, at the same time, vulnerable. Stakeholders associated with its dynamics of hatred, violence, and drugs will be pragmatic, generating new scenarios of risks and threats in the VRAEM areas, that are necessary to foresee with effectiveness and anticipation. Time is ticking against Shining Path, because if it does not demonstrate with short-term concrete actions that they can continue to be in control of drug trafficking and instead continue to lose capabilities it will make them more vulnerable. At the same time, other locals will take over those spaces that Shining Path will not be able to cover, producing significant changes in the dynamics of violence and illegality in the area. The level of business insecurity and distrust regarding the government’s capabilities in order to confront Shining Path were accentuated to the maximum: workers resigned and work stopped, there was risk of abandoning the project, as well as serious assessments on the continuity of business and important investment projects for the infrastructure within the area are facts that nowadays are being reconsidered. By Dialogo August 16, 2013 Today, the CCFFAA capitalizes on their hard work to confront the remnants of the Shining Path since 2007. The value of lessons learned, the application of international standards to support, equipm, train, and manage, as well as the morale of the Joint Special Forces and Intelligence personnel are the basis for success that gives President Humala not only a relief regarding his questioned security administration, but also a valuable space for initiative in the fight against Shining Path and drug trafficking that cannot be overlooked. Today, the challenges for the government are higher than before ‘Alipio’ and ‘Gabriel’ were defeated; on one hand, managing the success of the operation by rescuing the fundamental aspects that made it possible entails, in terms of National Defense, recognizing the advantages and boosting the development of joint operations under one command that projects over the whole dynamics of the fight against Shining Path in the VRAEM and against drug trafficking. This will constitute the basis for the progressive recovery of trust against insecurity, not only of investors and enterprises, but also from the population in general. On the other hand, the demands for addressing citizen security issues will be greatly increased. It is inevitable to relate the blow that the Shining Path is suffering, from the attack perpetrated against the Consorcio Vial Quinua facilities, in Huanta province (Ayacucho) on July 24, where (comrade) ‘Alipio’ conducted the destruction of important machinery and equipment used for road maintenance in that sector.

(WBNG) — While the coronavirus has continued to wreak havoc on our economy, the Binghamton-area is doing better than most. Even though the unemployment rate dropped about four and a half percent over the past month, since May 2019, unemployment has skyrocketed by more than 175%. The average unemployment rate in the state was 14.5%. Other industries that added jobs over the past month include leisure and hospitality, trade and non-farm jobs as a whole. The public sector, including government and education, lost jobs in the Binghamton Metro Area in May. The New York State Department of Labor says the Binghamton Metro Area had an unemployment rate of 10.6% in May, which was the third lowest unemployment rate of the 18 metro areas in New York. While the Department of Labor told 12 News it couldn’t say for sure why Binghamton had a relatively low rate, department statistics show the area did see a big boost in service jobs from April to May.

The United States on Wednesday saluted the protesters of Tiananmen Square and pressed China for a full account of the dead from its 1989 crackdown, with Secretary of State Mike Pompeo meeting survivors.The United States issues a similar statement for each anniversary but the timing this year was awkward as President Donald Trump has threatened military force against nationwide protests over racial injustice.Pompeo released a photo of himself meeting four figures from Tiananmen Square including Wang Dan, perhaps the most prominent of the student leaders behind the massive demonstrations for democratic reforms. Topics : The historic St. John’s Episcopal Church had suffered fire damage as nationwide protests gave way to riots over the killing by Minneapolis police of an unarmed African-American man, George Floyd.While the non-lethal force in Washington’s Lafayette Park was a far cry from Tiananmen Square, Hong Kong’s pro-Beijing leader has accused the United States of double standards in criticizing the city’s own clampdown on protesters demanding preservation of autonomy.Pompeo earlier denounced China for preventing an annual Tiananmen commemoration in Hong Kong on the grounds that mass gatherings went against guidelines in fighting the coronavirus.Trump in 1990 said that China’s leaders “almost blew it” in Tiananmen Square but ultimately showed “the power of strength,” comments on which the real-estate tycoon faced criticism as he ran for president. “We reiterate our call for a full, public accounting of those killed or missing,” State Department spokeswoman Morgan Ortagus said in a statement.”We mourn the victims of June 4, 1989, and we stand with the people of China who continue to aspire to a government that protects human rights, fundamental freedoms and basic human dignity,” she said.China’s leadership has never provided a death toll from the crackdown, in which hundreds if not thousands are believed to have been killed, and has sought to suppress all public mention of the episode.The anniversary comes several days after US federal police fired smoke bombs and pepper balls, a projectile that releases a chemical irritant, to break up a peaceful protest outside the White House so Trump could walk through to take a picture outside a nearby church.

The Lancashire Country Pension Fund and the London Pensions Fund Authority (LPFA) have announced a partnership to create a £10bn (€13bn) pooled investment fund as both schemes look for cost savings and improved governance.It comes as the UK government looks to legislate changes to Local Government Pension Schemes (LGPS), aiming to create two collective investment vehicles for listed and alternative investments.Both pension schemes currently employ in-house investment teams and have stated they wish to increase internal investment expertise.The so-called asset and liability partnership will see the funds merge investment expertise and liability management and will eventually cover all areas, including administration. Investments will be run by an external fund authorised by the Financial Conduct Authority (FCA) and owned jointly by the two funds.The £4.9bn LPFA, created by the merger of several legacy pension arrangements stemming from the abolition of the Greater London Authority, now administers around 20,000 members.The £5.3bn Lancashire Pension Fund provides pensions to 150,000 public sector workers in the North-West English county.Susan Martin, chief executive at the LPFA, told IPE that, aside from pooling assets, the new fund would allow the growth of viable asset classes.The partnership will also improve the funds’ governance and administration, she said.“Liability management starts with having accurate data and ends with finding assets that match liabilities,” she said.Martin added that the structure of the partnership and how it would work in practice were still being discussed with Lancashire, with no firm decisions on which personnel from which scheme would lead the investment fund or where it would be situated.She also said both pension funds had to focus on setting up the partnership in the best interest of members and would not seek any additional pension fund contributors until fully operational.The LPFA shaved nearly £400m from its deficit over the year to April on the back of investment returns and the revamping its fund structure.Martin said this was evidence that the two pension funds could scale up and achieve better investment returns and internal cost savings by working together.Councillor Jennifer Mein, leader of the Lancashire County Council, said the partnership would allow the fund to build on its “proactive approach” to asset and liability management.“The government should be using the good practice of funds to drive up the performance of the Local Government Pension Scheme, rather than dumbing down to the average,” she said.The government is expected to announce its decision on the future of the LGPS in early 2015.Both pension funds responded to government consultation suggesting that mandating switches to passive investment was not the answer to reducing deficits in the LGPS, with more collaboration on governance and liability management mooted as a more appropriate solution.Lancashire previously indicated that it would overhaul its asset allocation, earlier this year tendering for transition managers that could handle mandates worth as much as £5bn ahead of “significant” allocation changes.Other London pension funds have also increased collaboration in recent months, announcing the launch of a collective investment vehicle, looking to reduce the cost of external asset management and allow greater exposure to illiquid assets.
