Status: Questions 2 and 4 answered in the negative. Questions 1 and 3 ARE STILL UNANSWERED, despite previous claims.
On the third page of Wolfang K. Seiler's paper "lambda-rings and Adams operations in algebraic K-Theory" (pp. 93-102 in Beilinson's Conjectures), it is claimed that the Grothendieck ring of representations of a given group $G$ over a given commutative ring $A$ modulo exact sequences is a special $\lambda$-ring. Here, "representations" means finitely-generated projective $A$-modules with a $G$-module structure. ("Special $\lambda$-ring" is what most people just call "$\lambda$-ring", as opposed to "pre-$\lambda$-ring".)
1. Does anybody know a proof of this? I don't understand the sketched proof in 1, and I don't have the reference (R. G. Swan, A splitting principle in algebraic $K$-theory, in: Representation theory of finite groups and related topics, Proc. Symp. Pure Math. 21 (1971), 155-159) either. I have been told that Atiyah-Tall has a proof, but I am very skeptical about it (and if it has a proof, then I am unable to find it amid all the geometry).
I know how this is proven for the case of a characteristic $0$ field (yes, this is in Atiyah-Tall, but it is trivial using characters). My problem is to show this over arbitrary commutative rings.
2. What if we take the Grothendieck ring modulo split exact sequences (i. e., modulo direct sums) rather than modulo all exact sequences? Is this still a special $\lambda$-ring? What if we work over some field? What if the group is finite?
Update on 2: This is easily seen to be wrong, even if the field is $\mathbb F_2$ and the group is the $2$-element group. In fact, applying Krull-Schmidt and considering the Jordan decomposition of the matrix $\left(\begin{array}{cc} 1&1\\\\ 0&1\end{array}\right)$, we easily see that the $\lambda^2\left(uv\right)=\left(\lambda^1\left(u\right)\right)^2\lambda^2\left(v\right)+\left(\lambda^1\left(v\right)\right)^2\lambda^2\left(u\right)-2\lambda^2\left(u\right)\lambda^2\left(v\right)$ equation is not satisfied if both $u$ and $v$ are the representation of the $2$-element group on $\mathbb F_2^2$ in which the generator acts as $\left(\begin{array}{cc} 1&1\\\\ 0&1\end{array}\right)$.
3. Can we hope for any reasonable results if we replace the group by a cocommutative bialgebra? Note that cocommutativity is required to define the exterior powers of an $H$-module (where $H$ is our bialgebra). What if the bialgebra is Hopf?
4. What if we remove the projectivity condition on representations of $G$? I know that removing the finite-generatedness condition is a very bad idea (in fact, it makes the Grothendieck group collapse because of the Eilenberg swindle), but I have seen nobody talking about the Grothendieck group of finitely generated but not-necessarily-projective modules. Is it that embarrassingly stupid?
Update on 4: Question 4 has now been answered by Ben Wieland in the comments to this post.
Oh, and I have already asked this question over the "field" $\mathbb F_1$. The answer is "no" to all three questions in this case. But I am interested in "real" rings and fields this time.
EDIT: I might be understanding what Seiler is doing in 1, but in this case, he is doing it wrong, so I think I am not understanding him.
If I am understanding him right, Seiler's somewhat cryptic formulation "where the module induced by $M$ itself has a one-dimensional quotient, given by the linear functions on $S\left(M\right)$" means that we consider the surjection $M\otimes S\left(M\right) \to S\left(M\right)$ which sends $m\otimes m_1m_2...m_k$ to $mm_1m_2...m_k$, and its kernel is then a projective $S\left(M\right)$-module with $\lambda$-dimension one less than that of $M\otimes S\left(M\right)$ (because for every exact sequence $0\to U\to V\to W\to 0$ and every $k\geq 0$, we have the equality $\left[\wedge^k V\right] = \sum\limits_{i=0}^k \left[\wedge^i U \otimes \wedge^{k-i} W\right]$ in $K_0$). Unfortunately $M\otimes S\left(M\right)$ and $S\left(M\right)$ are not quite $S\left(M\right)$-modules with $G$-representations, because $G$ does not act $S\left(M\right)$-linearly on them (unless I did something wrong). Also we need a device to conclude that two projective $R$-modules $V$ and $W$ with $G$-module structure are equal in $K_0$ if and only if the corresponding $S\left(T\right)$-modules $V\otimes S\left(T\right)$ and $W\otimes S\left(T\right)$ with $G$-module structure are equal in $K_0$, where $T$ is some projective $R$-module; this looks like it should follow from the gradedness of symmetric algebras, but I don't see how (mostly because I have no idea what equality in $K_0$ actually means in terms of modules).

4: Finitely generated but not projective (or at least perfect) modules are not closed under derived tensor product. eg, $A=k[t]/t^2$, $M=k$, then $Tor_n(M,M)=k$ for all $n$. So you have a Grothendieck group but it isn't a ring, let alone a $\lambda$-ring. – Ben Wieland Mar 11 '13 at 4:06
Hmm... What is derived tensor product? Why is it important? – darij grinberg Mar 11 '13 at 4:44
Tensor product is not exact, so it is not defined on the equivalence classes in $K$-theory. The main motivation for derived tensor product is to make it exact. One application is that if $A$ is regular noetherian, $K$ of fg $A$-modules is a ring. A more elementary way is to say that $K$ of fg equals $K$ of projective, where the latter has a ring structure by regular tensor product. (I'm not answering the question "what?") – Ben Wieland Mar 11 '13 at 5:04
Ah!! This explains the focus on projectivity. One more question solved, thank you! – darij grinberg Mar 11 '13 at 5:29
1 Answer 1
After wondering about this question, I went and looked up Swan's paper. His argument is basically the one Seiler is trying to say; it also uses a paper by J. Burroughs: _URL_ which I have not looked at. According to Swan, his result only applies to the case when $A$ is noetherian for technical reasons, but that the general case would be discussed more generally elsewhere.
In the case of interest, suppose $C$ is the category of $G$ representations over $A$. Given an object $M$ of $C$, you are supposed to consider a category $C'$. In this case, this is a category of graded $S(M)$-modules with compatible $G$-action; that is the objects are graded $S(M)$-modules $Q$, together with a $G$-action on $Q$ such that the action map $S(M)\otimes Q\to Q$ is $G$-equivariant; here $G$ is acting in the evident non-trivial way on $S(M)$.
Seiler's (and Swan's) map $M\otimes S(M)\to S(M)$ is a morphism in $C'$, so you get a splitting relation of the form $[K]+[S(M)]=[M\otimes S(M)]$ in $K_0(C')$.
Swan then has an argument that the map $K_0(C)\to K_0(C')$, induced by tensoring up, is injective. I find it hard to parse, and don't really understand it.

SAFE THERMAL LOADS
The evaluation of a railway car wheel design should include studies of the wheel's response to thermal and mechanical loadings. The damage caused by these loadings is a major indication of the value of a given wheel design. Due to the complexity of the problem, there certainly does not appear to be a unique procedure for this analysis. At the University of Illinois we have proposed a simple model which retains the sophistication necessary to reasonably represent the problem. The method includes an elastic-plastic thermal stress analysis using material properties as a function of loading rate and temperature. Residual stress changes from the thermal loading are considered along with the oscillating stresses developed from the rail load that are conducive to fatigue damage. Experimental results are presented for comparison with theory.

How does music change shopping habits?
The constant background of pop music is something most shops and malls have in common.
But some of Britain's shopping centres may be about to become a lot quieter.
Hammerson, which runs a number of shopping malls across Britain, is thinking of phasing out music because of the effect it has on shoppers.
To find out the impact that sound might have, it has been carrying out some experiments.
The BBC's media correspondent, David Sillito, went to the Bullring shopping centre in Birmingham to find out more.


LCFS Hashing in Data Structure
Data StructureAnalysis of AlgorithmsAlgorithms
In this section we will see what is LCFS Hashing. This is one of the open-addressing strategy, that changes the collision resolution strategy. If we check the algorithms for the hashing in open address scheme, we can find that if two elements collide, then whose priority is higher, will be inserted into the table, and subsequent element must move on. So we can tell that the hashing in open addressing scheme is FCFS criteria.
With the LCFS (Last Come First Serve) scheme. The task is performed exactly in opposite way. When we insert one element, that will be placed at position x0. If the place is already occupied by element y, because yj = x0, then we place y at location yj+1, possibly displacing some element z and so on.
According to Poblete and Munro, the expected search time after inserting n elements in an empty table can be bounded by the following formula.
$$E[W]=1+\Gamma^{-1}(\alpha n)\lgroup1+\frac{ln\:ln\:\frac{1}{1+\alpha}}{ln\:\Gamma^{-1}(\alpha n)}+O(\frac{1}{ln^{2}\:\Gamma^{2}(\alpha n)})\rgroup$$
Here Γ is the Gamma function, and
$$\Gamma^{-1}(\alpha n)=\frac{ln\:n}{ln\:ln\:n}\lgroup1+\frac{ln\:ln\:ln\:n}{ln\:ln\:n}+O(\frac{1}{ln\:ln\:n})\rgroup$$

The mce4 operon is reported to be involved in cholesterol utilization and intracellular survival of Mycobacterium tuberculosis (M. tuberculosis). The regulatory mechanism of this important operon was unknown so far. Here we report detection of the promoter region and regulatory factors of the mce4 operon. The in silico analyzed putative promoter region was cloned in promoter selection vector and promoter strength was measured by O-Nitrophenyl-β-d- galactopyranosidase (ONPG) assay. The transcription start site was determined by 5′ Rapid amplification of C terminal end (5′RACE). Surface stress, hypoxia and presence of cholesterol, were found to be stimulatory for mce4 operon promoter induction. Pull down assay coupled with 2D gel electrophoresis resolved many proteins; few prominent spots were processed for identification. MALDI TOF-TOF identified proteins of M. tuberculosis which supported the regulatory function of the identified promoter region and cholesterol utilization of mce4 operon. Since mce4 operon is involved in cholesterol utilization and intracellular survival of M. tuberculosis in the later phase of infection, identification of the promoter sequence as reported in the present communication may facilitate development of effective inhibitors to regulate expression of mce4 operon which may prove to be a good drug target to prevent latency in tuberculosis.

This should make sense. A system wants to minimize its total energy, and the fermions would pack into the lowest energy states first. If the temperature is low, there is little thermal excitation to promote any fermions to orbitals with higher energy.
The Ground State of a Fermi Gas
We can solve for the Fermi energy by setting the total number of particles below that energy equal to the total number of particles in the system. We obtain:
= (3Π2n)2/3
We use the term "ground state" to refer to the state in which no fermions are excited to higher energy states beyond the Fermi energy. We can calculate the energy of the ground state by summing up the energies of the orbitals below the Fermi energy, to obtain:
Ugs = N
We can go through and calculate all of the other relevant quantities just as we did for the ideal gas.
The Fermi gas appears throughout any study of physics. Electrons form a Fermi gas. The electrons in a metal, the "sea of electrons", act as a Fermi gas. In astrophysics, white dwarf stars are prevented from collapsing upon themselves by the pressure of the Fermi gas and the resistance it gives to having its orbitals pushed together.
Bose Gas
A Bose gas is a gas consisting of bosons. We will treat the topic briefly as above with the Fermi gas.

The packer is one of Tk's geometry-management mechanisms.
Geometry managers are used to specify the relative positioning of the positioning of widgets within their container - their mutual master. In contrast to the more cumbersome placer (which is used less commonly, and we do not cover here), the packer takes qualitative relationship specification - above, to the left of, filling, etc - and works everything out to determine the exact placement coordinates for you.
The size of any master widget is determined by the size of the "slave widgets" inside. The packer is used to control where slave widgets appear inside the master into which they are packed. You can pack widgets into frames, and frames into other frames, in order to achieve the kind of layout you desire. Additionally, the arrangement is dynamically adjusted to accommodate incremental changes to the configuration, once it is packed.
Note that widgets do not appear until they have had their geometry specified with a geometry manager. It's a common early mistake to leave out the geometry specification, and then be surprised when the widget is created but nothing appears. A widget will appear only after it has had, for example, the packer's pack() method applied to it.
The pack() method can be called with keyword-option/value pairs that control where the widget is to appear within its container, and how it is to behave when the main application window is resized. Here are some examples:
fred.pack() # defaults to side = "top" fred.pack(side = "left") fred.pack(expand = 1)

Inaugural Interdisciplinary Science Research Lectures: A smart wound dressing concept for detecting and treating infection in paediatric burn wounds
One of the missions of the IScience programme is to demonstrate the symbiosis of teaching and research. The Interdisciplinary Science Guest Research Lecture series aims provide lectures accessible to undergraduates and non-experts to raise awareness of current interdisciplinary research topics.
On 24th November 2011 our first speaker Dr Toby Jenkins, Head of Biophysical Chemistry Research at the University of Bath, discussed the science behind the creation of a smart wound dressing for detecting and treating infection.On 24th November 2011 our first speaker Dr Toby Jenkins, Head of Biophysical Chemistry Research at the University of Bath, discussed the science behind the creation of a smart wound dressing for detecting and treating infection.
There is frequent reference to 'nanotechnology' in the media, and many people, including Prince Charles, have an opinion on its merits – or otherwise. However, few people seem to know exactly what nanotechnology is – including many scientists. Still fewer have heard of 'nano-biotechnology': the applications of nanotechnology to biological systems.
Toby discussed one potential clinical application of this technology. The problem of infection, especially with the evolution of drug-resistant bacteria, such as MRSA, is well known but it is less known that infection is a cause of death in half of all people who die from thermal burns. The focus of the technology Toby and his team are developing is to treat burns in young children. This is part of a research project currently taking place across five European countries, applying nano-biotechnology to the fabrication of an advanced wound dressing which will monitor whether a wound or burn is infected by bacteria. If the wound becomes infected, the dressing will automatically release an antimicrobial agent and, if this fails to stop the infection, then changes colour to alert the patient or clinicians.
Collaboration to create new Sustainable Development module
A collaboration between the Centre for Interdisciplinary Science and the School of Biological Sciences has received funding from the HEA Bioscience Centre to create a new module on sustainable development. The Departmental Teaching Enhancement Scheme will provide funding to the develop sustainability literacy teaching for students in Biological sciences and in the College of Science and Engineering. This new module will build on the existing option for Interdisciplinary Science students by broadening the scope to include sociological, ethical and economic issues beyond the usual conservation biology option.
Science and Sustainability: Improving Livelihoods in Kenya
Students from the University of Leicester have left a lasting impression on local community groups in Lake Naivasha, Kenya, after visiting in April this year. They visited Naivasha as part of the Sustainable Livelihoods field course, which is run each year by the Centre for Interdisciplinary Science. The course allows students to apply skills learnt during their degree to tackling real world issues of sustainability. This year's student projects – 'Reduction of fluoride in drinking water' and 'Briquette making' - were particularly successful in raising awareness of key issues and transferring knowledge to local communities.
Although fluoride is added to drinking water in some areas of the UK, very high levels of fluoride can have a negative effect on human health. Students Amy Cook and Ashleigh Glossop found that drinking water from bore holes around Lake Naivasha had fluoride concentrations well above WHO guidelines for safe levels. Some people in the area had already taken steps to reduce fluoride in their water; however Ashleigh and Amy found that many people were unaware of the health risks of fluoride. They tested a simple method of reducing fluoride concentration in drinking water, using carbonised animal bones, and found it to be successful.
I-science students Alicia Peel and Zoe Bailey worked on a project researching and creating different "Briquettes" – a fuel source made from compressed waste material - with the intention of introducing them to local communities as an alternative to charcoal.
Zoe said, "We looked at how these Briquettes could be advantageous to local communities and how different characteristics of the Briquettes (e.g. ratios, components or preparation method) affected how effective they were a fuel source. We also investigated how charring [carbonising] the Briquettes or the components of the Briquettes affected their efficiency, as well as looking at a couple of possible methods of charring."
Zoe and Alicia found that, overall, charred Briquettes worked best (they burned hotter and gave out less smoke); however, non charred Briquettes still worked well and are simpler to produce. Briquettes have a number of benefits for local communities. They are made from waste material and therefore provide a low cost alternative to charcoal, they can also provide a sustainable livelihood for people making and selling the Briquettes. If Briquettes become widely adopted in the area they should help to reduce the environmental damage caused by the production and burning of charcoal.
Students worked with a number of local community groups including the Lake Naivasha Disabled Environmental Group (LNDEG). These community groups have now implemented some of the suggestions put forward by the students and they have found the information very useful. Thadius Mogendi, Chairman of the LNDEG, has kept in touch with the students by email to keep them up to date with the progress they have made since April.
Ed Morrison, a PhD student working on wetland restoration in Naivasha, worked with the students. He said, "The briquettes have helped disadvantaged communities, with no access to electricity, reduce their dependence on environmentally-destructive charcoal production. The students supplied the materials and training necessary for the LNDEG to produce biomass briquettes from locally-available and otherwise discarded waste materials. They are now busy selling this alternative fuel in the settlement, at KSh 3/briquette [2p] and helping to spread knowledge about re-use of wastes towards affordable and environmentally-positive fuel production for the rural poor, reducing local rates of deforestation in the process."
As well as helping local communities in Kenya, the students who take part in the field course also get a lot out of the experience. Zoe Baily said, "I really enjoyed the Kenya field course. Being in Kenya was a really great experience, I loved getting to meet the local people and learning what life was like for them. It was amazing to be able to experience an environment so beautiful and different from what I am used too."
Zoe went on the say, "I think the best part about the field course was that I got to work on my own project that I knew could actually be of real benefit to the local communities. I was especially pleased when I recently received an email update from the Lake Naivasha Disabled Environmental Group informing us that, after the presentation Alicia and I gave, they are now producing and selling Briquettes."
The Sustainable Livelihoods course is run by Emma Tebbs, Graduate Teaching Assistant for the I-Science course, and Dr David Harper, originator of the module, who is a Senior Lecturer in Ecology & Conservation Biology in the Biology Department. David also teaches ecology on the I-Science degree by running the 'Biosphere' module and sustainability by contributing to 'Sustainable Futures'. He has conducted scientific research in Kenya & Tanzania for over 25 years, focussing upon the sustainability of water resources.
The field course will take place again in 2012 during the Easter holidays, when another group of students will travel to Kenya to work on a new set of projects. The course is open to anyone at the university. Anyone interested in taking part can find out more by contacting Emma Tebbs – _EMAIL_.


EE signal Booster
How did EE Signal Boosters work?
EE Signal Booster as we know it serves as the largest telecommunication provider in all of the UK. It provides the fastest 2G, 3G, and 4G.So to understand further you need to understand what a signal box is.
What is a signal box?
Getting a good network at home may sometimes cause a little headache as some types of glass, basements, and thick walls may hinder your signal strength.
A Signal box is a device that uses a broadband connection to give you the best reception around the house. It connects to your router and obtains signals from the network to provide strong indoor coverage.
For this to work effectively you will need;
 - A 3G compatible phone on EE
 - A spare Ethernet port on the router
 - A spare power supply near your router
How EE signal booster works
How to use your signal box?
Once purchased and activated your signal box will pick up automatically and start working. The green light flashes slowly and you hear a beep at the start of every call.
A signal box can allow a connection of up to four people at a given time; this can however be limited to one or two people if you have a slower broadband connection.
If you move further from the range of the signal box while you are in a call your call may drop unless there's an EE signal within.
You also need to have a phone that supports 3G for the signal box to work. Older 2G phones cannot use the signal box.
EE Signal Boosters work
What do the lights indicate?
 - Green light flashing quickly
If this happens try unplugging it and then reconnecting it again as this may signal a lost connection with the service provider.
 - Red light single flash
Signal box may be improperly connected, you should check if the cables are properly plugged in to the router and signal box. If this persists try changing the Ethernet cable and leave it for some time to see if it resets.
 - Red light – sequence of two flashing lights
Internet connection is not being received by the signal box. You should check the connection of your broadband.
 - Red lightsequence of three flashing lights
This signals something else might be interfering with the signal. You have to make sure the signal box is not close to any other electrical equipment and that it is at least 60cm away from the router.

Gain control over your managed and unmanaged devices with Network Glue
Network Glue has evolved into more than just a network diagramming solution. It can help you gain comprehensive visibility into your network with features like automatic discovery, documentation, diagramming and more.
IT Glue can ensure secure and quickly accessible documentation, and Network Glue can automate all your network information. Having Network Glue data automated right into IT Glue will enhance your ability to centralize the network information you need to do your work efficiently.
In this blog, we'll explore some Network Glue feature updates that can make network documentation simpler and more efficient.
Unmatched Devices Notification
IT professionals typically maintain a well-kept list of managed devices since they can get that information from their RMM solution. But what about unmanaged devices like VoIP, firewall, servers and more?
To provide proper service to their clients, IT professionals need to get a complete picture of all the devices in their clients' networks, both managed and unmanaged. This helps them understand how these devices relate to each other. This high-level visualization of networks and devices will prevent unresolved issues and benefit your clients as well as your business.
MSPs must have enhanced visibility into their clients' networks, and that starts with identifying every single device in their clients' networks. This is now possible with our new automatic notification of unmatched devices. You can set this up as a new workflow type to receive regular emails that will show you a list of unmatched devices.
Once Network Glue detects a device that is not already documented in IT Glue or an unmatched device, it will be listed in your automated email notification. Your technicians can then decide whether to match the device or document it in IT Glue.
This will give you the peace of mind you need to focus on bigger, more important tasks, knowing that the possibility of missing new devices in your network has been eliminated.
Switch Port Enhancement
Knowing what is connected to each port on a switch is important for you to troubleshoot easily. Not only does Network Glue automate the documentation of devices & Active Directory contacts, but it also automates the documentation of ports and interfaces.
With the latest Switch Port update, now under any IT Glue device, you can easily see anything the device is connected to, including other IT Glue configurations or even unmatched devices discovered by Network Glue.
If the unmatched device is key to your IT documentation, you can now add this newly discovered unmatched device right away to your IT Glue account. Using the "Add to IT Glue" button, you will be redirected to the Network Glue diagram with the selected device, and you can then match it there. However, even if you do not do this, the connected port information will still show.
To learn more about these new updates, request a demo.

In 2018, Wetlands International South Asia and the Center for Water Resources Development and Management formulated integrated management plans for three Ramsar Sites of Kerala, namely Sasthamkotta, Ashtamudi, and Vembanad-Kol. The three plans were approved for implementation by the state government last year. The Ministry of Environment, Forest and Climate Change, under its National Plan for Conservation of Aquatic Ecosystems, provided its share of grants for the implementation of the management action plans in the current financial year.
A meeting was held by State Wetlands Authority Kerala, the nodal agency for managing wetlands in the state, for discussing monitoring and capacity development arrangements. In the day-long meeting held on August 5, 2019, Dr Ritesh Kumar, Director, Wetlands International South Asia elaborated steps for systematic monitoring of the wetland system and the management plan implementation. The implications for implementing the Wetlands (Conservation and Management) Rules, 2017 were also discussed at length. A road-map for conducting structured capacity development of various line departments engaged in management plan implementation was elucidated.


text: This paper experimentally evaluates continuum deformation cooperative control for the first time. Theoretical results are expanded to place a bounding triangle on the leader-follower system such that the team is contained despite nontrivial tracking error. Flight tests were conducted with custom quadrotors running a modified version of ArduPilot on a BeagleBone Blue in M-Air, an outdoor netted flight facility. Motion capture and an onboard inertial measurement unit were used for state estimation. Position error was characterized in single vehicle tests using quintic spline trajectories and different reference velocities. Five-quadrotor leader trajectories were generated, and followers executed the continuum deformation control law in-flight. Flight tests successfully demonstrated continuum deformation; future work in characterizing error propagation from leaders to followers is discussed.

NIOSH Releases Two Guidelines for Titanium Dioxide
Current Intelligence Bulletin 63 is the first time the agency has issued separate guidelines for the same chemical based on particle size.
NIOSH for the first time has released two guidelines for the same chemical, titanium dioxide, based on particle size. The agency released its Current Intelligence Bulletin 63: Occupational Exposure to Titanium Dioxide on April 14.
Titanium dioxide is an insoluble white powder used in paints, cosmetics, plastics, paper, and food; the guidelines indicate ultrafine particles of TiO2 are more hazardous by inhalation to workers than fine particles of the chemical. The TiO2 CIB makes recommendations for occupational exposure limits and suggests techniques for monitoring and controlling exposures.
- Reviews data relevant to assessing the carcinogenicity and other adverse health effects of TiO2.
- Provides quantitative risk assessments and recommended exposure limits for fine and ultrafine TiO2. NIOSH said laboratory data shows ultrafine particles "demonstrated greater potency in laboratory rats than fine particles did, when the dose was expressed by particle surface area. This greater potency was associated with the greater surface area of the ultrafine particles for a given mass."
- Describes exposure monitoring techniques, exposure control strategies, and future research needs.
"The guidance in this Current Intelligence Bulletin will protect workers also in reflecting our efforts to use our science to better understand and address particles on the nanoscale," said NIOSH Director Dr. John Howard. "As NIOSH continues to conduct research into the occupational health implications of nanotechnology, guidance of this nature will play an increasingly important role in fashioning protective occupational safety and health practices."

Testing General Relativity Principles
The precession of the orbital node of a particle orbiting a rotating mass is known as Lense-Thirring effect (LTE) and is a manifestation of the general relativistic phenomenon of dragging of inertial frames or frame-dragging. The LTE has been measured by using the node drifts of the LAGEOS satellites and GRACE-based Earth gravity field models with an accuracy of about 10% in the recent years. With the LARES experiment launched in 2012 an improvement down to a few percent is anticipated.
A new in-house LAGEOS analysis incorporating a suite of recent gravity field models confirms the 10% level. An example graphical representation of the combination of LAGEOS and LAGEOS-2 data over the years 2000-2016 based on the EIGEN-GRACE03S gravity field is given here. The green line shows the LTE node drift, a regression reveals 46.6 mas/a (milliarcseconds per year) versus a theoretical value of 48.2 mas/a, so a deviation from the prediction by 3%. The red dots show the observed node differences every seven days, eventually being accumulated to yield the green line.
We also investigated the potential of GALILEO to contribute in testing the LTE. It turned out that the solar radiation pressure effects will most likely hide the LTE, however with some proper knowledge of the satellite surface properties and by averaging over the full constellation and by a proper tuning of the POD there remains a chance though. So we will keep up our interest into this for the GALILEO operational phase.

Jelqing is the train which guys have been doing with the intention to improve penis dimension. There are dozens upon dozens of how to jelq. Listed here are the 5 handiest jelqing routines immediately:
1. Customary Jelqing. Sure, the most effective jelqing routines is definitely the straight up, old fashioned, customary jelqing. This has been the spine of nearly each stable jelqing program, so one cannot ignore how efficient it has been all through the years. An ordinary routine can also be the closest to how unique jelqing began, supposedly a whole lot of years in the past with tribes. Let's go over a typical routine:
- Penis is lubricated and semi-erect.
- Thumb and forefinger are joined, making a circle which is wrapped across the base of the penis.
- Ahead, sluggish and managed movement of about 2-Four seconds.
- Grip is relased proper earlier than the pinnacle.
- Identical factor with the opposite hand, after which repetitions are repeated alternating arms for a number of minutes.
2. Jelqs and Stretches. This can be a highly regarded option to carry out enlargement workout routines. It's mainly customary jelqing with stretching particular workout routines carried out both in between jelqs, or, as is extra customary, carried out as a "nearer train" after your requirements are accomplished. Stretches work for providing you with that additional increase for elevated size positive aspects. This is how jelqs and stretches are put collectively in a routine:
- Customary jelqing as described above is carried out.
- Relaxation for a second after which start stretches by gently out-stretching the penis.
- This stretched out place is held for a number of seconds, then launched.
- Repeat the stretch and maintain once more, and proceed for a variety of repetitions.
three. Bathe Jelqing. That is thought of the most effective jelq routines, for a number of causes. First it's the one routine that almost all guys follow as a consequence of it is comfort issue. Most males fail with jelqing due to the weird nature of doing the train. You do not go to a fitness center, or down your basement or storage to exercise. You need to discover a very non-public area the place you will not be disturbed for a number of minutes. Most guys will strive a number of completely different preparations, however by no means get right into a set routine, which is vital for making this enlargement train actually work.
The shower is a perfect place for doing jelqs. It is non-public and it is already a part of a routine that you just do anyway. The opposite purpose it is very efficient is that it warms your penis up a lot sooner, should you direct the nice and cozy water in direction of the penis originally of the train. After you end along with your jelqs, you'll be able to as soon as once more direct heat water down there which relaxes the penis and prepares it for relaxation, restoration, and development.
Four. Reverse Jelqs. This can be a nice train which focuses on girth positive aspects. Many guys have been turning to jelqing particularly to achieve thickness of their dimension. Girls are way more involved about girth than size, in response to many stories asking them "does penis dimension matter?" Reverse jelqs work on increase girth dimension. This is how they're normally carried out:
- As an alternative of the usual "semi-erection" to start out, normally round 40-60%, reverse jelqing has the penis at a barely larger erection begin dimension, round 60-70%.
- The identical movement ahead is initiated, however simply earlier than the pinnacle, as an alternative of releasing, the hand movement is then reversed again to the bottom.
- That is then repeated for a sure variety of units and reps.
- Typically completely different grips, such because the "V-grip", are used when performing reverse jelqs.
5. Jelqing plus Supplementation. The newest jelqing routines have been combining each customary jelqing and stretching, with supplementation. There are usually two sorts of supplementation used with a jelq program.
- Natural based mostly capsules which improve blood circulation. These are capsules that promote elevated blood circulation to the penis. They're normally marketed in direction of more durable and stronger erections, however for guys having hassle staying erect all through a full jelq routine, these capsules can assist hold you in that regular semi-erect state.
- Pure testosterone and/or development hormone dietary supplements. The mixture of all pure take a look at boosters or development hormone dietary supplements, alongside performing jelqing workout routines, has been seen to enhance development and ship sooner outcomes. This has been the newest development when performing enlargement workout routines.

||A novel probe of chiral restoration in nuclear medium
Gubler, Philipp ,
Kunihiro, TeijiLee, Su Houng
340 , 2017-04 , Elsevier BV
We propose measuring the mass shift and width broadening of the f1(1285)meson together with those of the ωfrom a nuclear target as a means to experimentally probe the partial restoration of chiral symmetry inside the nuclear matter. The relation between the order parameter of chiral symmetry and the difference in the correlation functions of the f1(1285)current and the ωcurrent is discussed in the limit where the disconnected diagrams are neglected. A QCD sum rule analysis of the f1(1285)meson mass leads to about 100 MeV attraction in nuclear matter, which can be probed in future experiments.

Jeopardy! (2010) is a Trivia/Board Game game published by THQ released in 2010.
Jeopardy! (2010) is considered a trivia / board game. Trivia games are based on testing the players knowledge of trivia, many times within a time limit. Most are single player but there are many that are also multiplayer. Board games usually mimic their real world counterparts like chess, checkers, and Monopoly.
Port Forward Jeopardy! (2010)
When you are playing Jeopardy! (2010) you might need to forward some ports in your router. Forwarding ports is a useful trick in gaming because it can really help to make your network connection most stable and sometimes even faster. Routers were not designed to allow incoming network requests and some games can play tremendously better if an incoming connection is forwarded through the router to the game.
Before You Forward a Port
Before you can forward a port you need to know the following things:
- The IP address of your router.
- Your gaming machine's IP address.
- A list of TCP and UDP ports to forward.
How to locate your router's IP Address
The easiest way to find your router's IP address is to run our free Router Detector utility. It's a part of the Network Utilities suite of tools and it's completely free to use.
How To Forward Ports
To easily and quickly get your ports forwarded use the Network Utilities software. Network Utilities allows you to forward ports only when you need them, and then close them again when you are done. This makes keeping your network more secure much easier. You can also do it by hand.
The general process for forwarding a port is:
- Start by logging in to your router.
- Locate your routers port forwarding section.
- Put the IP address of your computer or gaming console in the proper box in your router.
- Put the TCP and UDP ports for your game in the matching boxes in your router.
- Sometimes you have to reboot your router for the changes to take effect.
Which Ports Does Jeopardy! (2010) Require
The exact ports for Jeopardy! (2010) are as follows:
Jeopardy! (2010) - Wii
- TCP: 6667, 12400, 28910, 29900, 29901, 29920
- UDP: 1-65535
We have guides that are custom tailored for Jeopardy! (2010) that will show you the incoming ports that need to be forwarded.
That's all it takes to forward your ports. For more on how to port forward, check out our list of games and applications.

Following Tony Blair's recent visit to Kosovo, where he met nine children named after him, the middle names of the children have come to light. These paint a rather different picture. All nine children were given the name 'Tonibler' following Nato's intervention in the Kosovo war. However, three of the children also have the middle name 'Lyingbastard', two 'Destroyerofworlds' and three others 'Initfortheoil'. The ninth child's middle name is unprintable.

 Very helpful
 I was wondering what to buy for my grandson last christmas and knew that my daughter really liked toys made by V-tech, she gave me a list of some to choose from. This particular one really caught my eye and is suitable for 1 to 3 year olds. It is a very soft cuddly, bright green Dinosaur named Numbersaurus. As you can probably guess from the name that it teaches your child numbers up to five. Numbersaurus has a blue and yellow fabric frill that goes over his head that is crinkly and sounds rather like a crisp bag being scrunched up when touched. It has two yellow horns above his eyes that light up red and flash, also a horn on top of his nose. His mouth is wide open and is red inside and when squeezed it squeaks. To turn him on you have to press his right paw, a little tune plays for a second and his horns light up and flash and he says (Hello). His left paw has a embroidered music symbol which when pressed plays 10 cheerful melodies of well known rhymes, that you can sing along to. His tummy contains the numbers and picture word buttons that are all embroidered and very colourful. The symbol of the trees says (Forest) and you then hear birds singing when pressed. The symbol of the sea says, (Sea) and you can hear the sound of water. The number one button also has a picture of the sun and the voice says both words. The number two button also has a picture of whales and the voice says both words. The number three button has a picture of carrots and the voice says both words. The number four buttons has a picture of leaves and says both words. The number five button has a picture of cherries and both words are said. The voice is actually animated but is still very clear to understand. He has a bright red pad on his left foot and a yellow pad on the other, all his claws are bright red, and he certainly is very eye catching. He needs feeding with two AA size batteries; t
 hey go into his back and are hidden by his bright red scales. In all this is a very charming soft toy, which is brightly coloured and has soft censor buttons that will help to develop fine motor skills. Just in case you are wondering what is meant by motor skills its really about co-ordination. Any way I forgot to mention to turn him off you just press his right paw and his horns flash and he says (bye-bye). It is an educational toy, which makes learning fun, and thats what it's all about.I paid £18.00 for this toy from my Freeman's catalogue, but I am sure he is available from most good toyshops, and probably cheaper too. I must say that my grandson was really taken by it, and loves playing with it, it makes him laugh and to see him chuckle gives me great pleasure and I know that it was worth every penny. I am sure he will have a few more years fun with it. Thanks for reading Cinystar

Using STL function objects in std::sort
Introduction
This article describes a simple STL function object. A function object is a way to create a function that maintains state. This is especially useful in sorting situations where a simple less-than or greater-than comparison just won't do.
std::sort
Like C's ancient qsort function, the STL std::sort function can accept a comparison function as one of its parameters. This comparison function is called by the sort function when it needs to compare two values from the array. A typical STL comparison function is:
bool compare_myObjects(const CMyObject &a, const CMyObject &b)
{
 return a.x < b.x;
}
You can use this function to sort a vector (array) of CMyObjects like this:
// declare the vector
vector <CMyObject> myArray;
... initialize the vector
.
.
.
// sort it
std::sort(myArray.begin(), myArray.end(), compare_myObjects);
This works fine in 99% of the situations you're likely to run into.
The other 1%
What if you need to sort the array based on information that isn't in either of the two objects, as might happen if the comparison needs access to some other non-global variable; or what if you want to sort one array based on the contents of another array? You could, of course, do this with global variables, but that's not nice. A function object, of course, can help you do it in a nice OO/C++ manner.
binary_function
A binary_function is a template that, in effect, allows you to define a class that can act as a binary operator - it accepts two inputs of type A and B and returns a single output of type C. It acts as a class, but also as a function, when used in functions such as std::sort. So, you can store things in the class, and use it to perform comparisons (or any binary operation, really) like the compare_myObjects function above.
Sorting one array based on another
For the following example, we have two vectors: one vector is an array of employee objects; the other is an array of integers. The array of integers is an array of indexes into the first array and we'll sort these based on the objects in the employee array. Assume there's some good reason why we can't just sort the employee array itself, like maybe it's been sorted already and we don't want to destroy its current order.
First, an employee:
class employee
{
public:
 int m_salary;
 string m_name;
};
Second, a binary function:
// this is our function object class.
// it holds a reference to a vector of employees.
class employeecomp : public std::binary_function<int,int,bool>
{
 // the vector reference
 const vector<employee> &m_employees;
public:
 // constructor which takes a reference to a vector of employees
 employeecomp( const vector<employee> & employees ) : m_employees(employees) {}
 // comparison operator. this will be called by std::sort with two
 // integers. we'll perform a comparison operation on the inputs and
 // return the result of the comparison.
 bool operator()(int a, int b) const
 {
 // a typical comparison operator compares the two input parameters.
 // this one uses the two input parameters as indexes into the m_employees vector.
 return (m_employees.at(a).m_salary) < (m_employees.at(b).m_salary);
 }
};
Using these things:
First, initialize the two vectors:
// index array. this is what we'll sort
vector<int> indexVector;
// employees. this is what the sorting of indexVector is based on
vector<employee> employeeVector;
// initialize indexVector
for (int i=0; i < 4; i++)
{
 indexVector.push_back(i);
}
// initialize some employees
employee h;
h.m_salary = 0;
h.m_name = "fred";
employeeVector.push_back(h);
h.m_salary = 99;
h.m_name = "ethel";
employeeVector.push_back(h);
h.m_salary = 32;
h.m_name = "ricky";
employeeVector.push_back(h);
h.m_salary = 23;
h.m_name = "lucy";
employeeVector.push_back(h);
pre-sort:
// show the index vector before sorting
printf("Before sorting\n");
vector<int>::iterator it;
i = 0;
for (it = indexVector.begin(); it != indexVector.end(); it++)
{
 printf("indexVector[%d] = %d\n", i, (*it));
 i++;
}
Sort! This is where it all comes together. The first two parameters are the start and end of the vector we wish to sort. The third parameter is known as the 'predicate'. In this case, the predicate is an employeecomp object that we're initializing with the employee vector. For every comparison that std::sort needs to do, it will call Pr(x,y), where Pr is the comparison function. In this case the comparison function is the "()" operator of the employeecomp object; x and y are two items from indexVector.
std::sort(indexVector.begin(),
 indexVector.end(),
 employeecomp(employeeVector)); // initialize our functor
post-sort:
// show the index vector after sorting
printf("After sorting\n");
i = 0;
for (it = indexVector.begin(); it != indexVector.end(); it++)
{
 printf("indexVector[%d] = %d\n", i, (*it));
 i++;
}
...the results:
Before sorting
indexVector[0] = 0
indexVector[1] = 1
indexVector[2] = 2
indexVector[3] = 3
After sorting
indexVector[0] = 0
indexVector[1] = 3
indexVector[2] = 2
indexVector[3] = 1
As you can see, the indexVector has changed. But what did it change to? The values in indexVector now show the indexes of the items in employeeVector, sorted by increasing salary. And, though I didn't show it here, the employeeVector was not modified at all.
This is a very basic example of what a function operator can do. Still, it's a technique that can be extremely useful in some situations. Because the binary_function template creates a fully functional class, there is no limit to the amount of complexity you can add to it (sort a vector of function objects, for example). Also, this technique isn't limited to std::sort; you can use it in many of the STL algorithms.
Enjoy responsibly.

We resurrect the infamous harmonic mean estimator for computing the marginal likelihood (Bayesian evidence) and solve its problematic large variance. The marginal likelihood is a key component of Bayesian model selection since it is required to evaluate model posterior probabilities; however, its computation is challenging. The original harmonic mean estimator, first proposed in 1994 by Newton and Raftery, involves computing the harmonic mean of the likelihood given samples from the posterior.
massmappy provides functionality to recover convergence mass maps on the celestial sphere from weak lensing cosmic shear observations. At present the spherical Kaiser-Squires estimator is implemented. Additional estimators will be added in future.
massmappy also supports numerous projection operator to project the sphere to planar regions for comparison with the spherical Kaiser-Squires estimator.
massmappy relies on the SSHT (built on the MW sampling theorem) and HEALPIX codes to handle sampled data on the sphere.
NSHT implements a novel sampling scheme to accurately sample a signal band-limited at $L$ in $L^2$ samples.
Whereas sampling theorems on the sphere require at best $\sim 2 L^2$ samples (see A novel sampling theorem on the sphere; implemented in SSHT), NSHT sampling achieves the optimal sampling rate specified by the dimensionality of band-limited signals in harmonic space. However, a theoretically exact sampling theorem in not obtained.
Nevertheless, NSHT provides functionality to compute fast spherical harmonic transforms for signals sampled according to the optimal sampling scheme developed.
optimusprimal is a light weight proximal splitting Forward Backward Primal Dual based solver for convex optimization problems. The current version supports finding the minimum of f(x) + h(A x) + p(B x) + g(x), where f, h, and p are lower semi continuous and have proximal operators, and g is differentiable. A and B are linear operators.
ProxNest is an open source, well tested and documented Python implementation of the proximal nested sampling algorithm, which is uniquely suited for sampling from very high-dimensional posteriors that are log-concave and potentially not smooth (e.g. Laplace priors). This is achieved by exploiting tools from proximal calculus and Moreau-Yosida regularisation to efficiently sample from the prior subject to the hard likelihood constraint.
PURIFY provides functionality to perform radio interferometric imaging, i.e. to recover images from the Fourier measurements taken by radio interferometric telescopes. PURIFY leverages recent developments in the field of compressive sensing and convex optimisation, adapted, in some cases extended, and applied to radio interferometric imaging.
PURIFY itself contains functionality specific to radio interferometry, whereas all sparse optimisation functionality is implemented in the companion code SOPT. SOPT provides very general algorithms for solving sparse regularisation problems and is being applied in many areas become radio interferometry.
The S2 code provides functionality to support functions defined on the sky and was developed primarily for astrophysical applications. More generally, however, any arbitrary function defined on the sphere may be represented. Both real space map and harmonic space spherical harmonic representations are supported.
Basic sky representations have been extended to simulate full sky noise distributions and Gaussian cosmic microwave background realisations. Support for the representation and convolution of beams is also provided.
S2DW provides functionality to perform the scale discretised wavelet transform on the sphere. Routines are provided to compute wavelet and scaling coefficients from the spherical harmonic coefficients of a signal on the sphere and to synthesise the spherical harmonic coefficients of the original signal from its wavelet and scaling coefficients. The reconstruction of the spherical harmonic coefficients of the original signal is exact to numerical precision.
Functionality to support functions defined on the sphere is provided by the S2 code.
S2FIL provides functionality to support optimal filtering on the sphere. Optimal directional matched (MF) and scale adaptive (SAF) filters may be constructed from a template and stochastic background process. Functionality is also incorporated to filter a sky data map with an optimal filter. Moreover, a simple object detection algorithm is implemented to extract embedded object parameters from the filtered field.
Functionality to support functions defined on the sphere is provided by the S2 code; template objects are defined in the COMB code; and functionality to perform fast directional filtering on the sphere is provided by the FastCSWT code.

History of the swan
The 'Swan Inn' was opened in 1861 by Mr George John Swann. Mr Swann had previously been manager at the Queen's Hotel during the period when the German Legion were camped on the Queen's Parade opposite the Hotel in 1857 on the Legion's return from the Crimea War.
Mr Swann did all the catering for this legion and with the profits made decided to start on his own account and became the first Landlord of the Inn and it became known as the 'Swan Inn".
An anecdotal story from the local newspaper tells us that on every Easter Monday there were sports held in the gardens, including cock fighting in pits.
The following is an extract from a letter from Mr Swann's grandson to the proprietor in 1949.
A Mr Cocks followed as Landlord until about 1880 when the Inn was taken over by Mr Reeves the father of Mr George Pryor Reeves who died at the Inn several years ago (1938).
The following items may be of interest to you:
The Architect who designed all the roads in this new part of Farnborough had his office and lodging at the Inn. In 1869 the Rateable Value of the Inn was 13.10.0 and the total ANNUAL Rates amounted to 27/- (Good old times).
There were two Parish Constables in 1869 each being paid the sum of 1.0.0 per year. Their names were J White and A Young.
In 1861 on the site which is now the R.A.E. there were usually a Brigade of Cavalry camped every Spring time and during the month of August the whole of the land now used for Flying was covered with tents accommodating about thirty thousand Volunteers and Militia.
The Inn was enlarged by adding the two bay window portions to give more room to the workers of the newly built Army Balloon Factory.
Until the 1890's it was all open ground opposite the Inn and the only exciting item was the running of the Trams from Farnborough Station to North Camp Station via "Queen's Hotel". The Trams always stopped at the "Swan" to refresh both horses and driver.

Graphene synthesis on large-area silicon wafers suitable for manufacture
The objective of the Phase I project was to demonstrate graphene synthesis on a silicon (Si) wafer with (001) orientation without relying on the transfer of a template layer or any other material from one substrate to another. This Phase I objective was successfully demonstrated using symmetry transformation layers (STL). The proposed Phase II objective is to further develop the STL concept for graphene synthesis. Reduction in maximum processing temperature will be pursued in Phase II. Maximum temperature of 1150 C or less is possible. Refinement of graphene synthesis parameters will be undertaken to improve the structural and electrical characteristics of graphene produced by this method. Characterization of the transport and optical characteristics of graphene will be performed with potential applications (e.g. rf communications, sensors, digital imaging and displays) in mind. Devices from one or more of these application areas will be demonstrated to assess potential product feasibility. Marketing of graphene/Si integrated materials is planned.

Mr David Nisbet, New stem cell strategies for nerve regeneration
David Nisbet a Monash PhD student from the CRC for Polymers has developed a technique which has the potential to revolutionise nerve regeneration using stem cells and "smart" nanomaterials. This major advance in stem cell research also provides a boost to the search for treatments for crippling conditions, particularly in the areas of Parkinson's Disease and spinal cord injury.
Nerves lost due to degenerative diseases or spinal cord injury are not regenerated and the consequences for the patient are severe. Engineering principles and stem cells will be used to regenerate damaged nerves restoring function to the patient. This will be achieved by engineering next generation polymer materials that assist stem cells in replacing damaged nerves.
A scaffold has been constructed that supports neural stem cells and provides important signals to assist nerves to regrow. The scaffold is generated from plant seeds and provides a three-dimensional platform and anchor point for the cells. It functions in a similar way as the temporary scaffolding in building construction – after the scaffold has served its purpose it degrades away leaving the cells to exist on their own natural matrix. These scaffolds are also capable of guiding nerves within the body to specific locations.

Winner – 3-minute presentation
Ms Emily Piper, Australian cattle producers are ticked off!
Emily Piper, a PhD student from the Beef CRC is aiming to find a clean, green way of controlling cattle ticks. Currently, synthetic insecticides are used to control the cattle tick (Rhipicephalus microplus) but they are costly to producers and their use could possibly leave residues in food products and the environment.
Found in tropical and subtropical environments worldwide, the blood-sucking cattle tick costs Australian cattle producers more than $175 million per year in control costs and lost production. Heavy tick infestation can also kill animals if they are left untreated.
Emily's work focuses on identifying the mechanisms responsible for "natural" host resistance against cattle ticks.
Some breeds of cattle such as the Brahman are naturally more resistant to the cattle tick and ticks will die rather than feed on them. However European breeds such as the Holstein-Friesian and Hereford become heavily infested when there are many ticks in the field. Controlling ticks by using resistant breeds is not new; however, it is difficult to identify highly resistant animals, especially in cross breed animals.
Emily has show that Brahman animals have a different profile of immune cells to that of the susceptible Holstein-Friesian animals. The Brahman cattle had more B cells and helper-T cells in their blood, while the Holstein-Friesian cattle had more macrophage type cells.

Woke Culture Jamming
There are many things about our community that I love, Woke Culture Jamming is one of them.
What do I mean by that? I mean that it's possible to see something for what it is, even if it's a dark or destructive impulse, acknowledge it, reject it and then use it.
For example, a person of color may be working on Black Lives Matter during the day, and then during play may want to integrate race play as part of their experience. Or a woman who is an argent feminist may want to be objectified during her play. Or a man who is a feminist may enjoy degradation as part of his play.
What makes them okay is their understanding of why. When we understand why something appeals to us, we can own it. Maybe our desires are an expression of some deep-seated dark impulse, or we just want to play with the idea of being evil, or being objectified/useless, of being the object of fear or being the monster.
Many of us live in a culture of repression. We do not express our desireswe often don't even allow them to rise to the surface.
But here we are safe. CEOs can be gimps. Doctors can be mindless fuckdolls. A poor grad student can be a queen, and a 65 year old grandpa can be a sissy dolly. This can and often does include some dark impulses, responses to our larger cultural forces. And that's not only okay... it's great.
Play is a place to be safe.

Software and Simulation Laboratory
The Software and Simulation Laboratory is where software technologies are demonstrated and hands-on software prototyping and testing carried out for the benefit of ESA projects and industry. It consists of equipment and computer installations to develop and test software as well as simulators and ground support equipment used in the development and verification of space systems.
What is Software Simulation?
Software is a critical component of space systems, both space and ground. As more functions and intelligence are implemented in software, its design and reliable operations have become a complex and highly demanding task. The flight software onboard a typical modern spacecraft stretches to hundreds of thousands of lines of code, while programs of similar elaboration oversee supporting ground systems.
Software of such complexity demands careful verification to guarantee that it operates correctly and does not endanger the achievement of the space mission. Software is intangible, but errors or omissions buried within it have very real effects, having led to the partial or complete loss of space missions.
The Software and Simulation Laboratory provides independent verification and validation of software developed for space. In addition the Laboratory also evaluates more efficient and reliable methods for designing software in future.
As well as being an important mission component, software is also a vital work tool. The Laboratory develops computer simulations both graphical, interactive 3D simulations of space hardware as well as simulations of satellite systems and missions which have many uses through an ESA project's life cycle, from initial design through to operational planning as well as training of astronauts and ground personnel. Software is also extensively used for ground-based testing of space hardware, as essential part of the so called Electrical Ground Support Equipment (EGSE). The EGSE can be connected to a satellite and check its correct performance by analyzing its responses to commands as if it were in orbit.

It is particularly suitable for filtering wine, water, infusions, beers, pharmaceutical solutions and perfumes. It does not require any particular maintenance besides normal cleaning. Filtering is the last step in the production of wine and requires knowledge of some fundamental precautions. A young wine (30 days) is not ready for fine filtering. By following our instructions, included in the box, you will find the right way to achieve a good filtering with the Filter Rover Colombo 6.
Liquids it can handle:
It is possible to use the pump to transfer any type of clean liquid in common use, which is not chemically aggressive or abrasive. Some examples: water, wine, milk, vinegar, low viscosity oily solutions, neutral fluid detergents, diesel.
After use, pour clean water to rinse the internal surfaces of the pump. The electric motor requires no maintenance, there are no parts to lubricate. The external parts must be cleaned with a slightly damp sponge, and then dried immediately with a cloth.

Study ancient remedies.
The goals of this project are:
 1. To determine the effectiveness of ancient remedies.
 2. To compare each remedy to its modern-day counterpart.
Research Questions:
 - What ancient remedies are still in use today?
 - How are medical treatments tested?
Long ago, the opal was considered a predictor of illness. This may sound whimsical until we understand that the opal loses its shine as temperature increases. Thus, an opal tucked under the armpit of a healthy person will be shinier than an opal tucked under the armpit of someone running a fever. In other words, the opal was the world's first thermometer. In this project you will analyze completed scientific studies of ancient treatments and remedies, and explain how they work, or how they don't.
 - Computer with Internet access
 - Color printer
 - Digital camera
 - Typical office/hobby/hardware/craft supplies (paper, poster board, glue, etc.).
Experimental Procedure:
 1. Read overview of relevant topics (see bibliography below)
 2. Address all of the terms and research questions mentioned here.
 3. Search and print out images relevant to your topic.
 4. Take photographs throughout the course of the experiment.
 5. Select a number of ancient medical treatments as the subject of your study.
 6. Create a visual chart that categorizes ancient remedies and illustrates the effectiveness of these treatments.

 considered as a primitive operation. Parallel prefix
 circuits are parallel prefix algorithms on the
 combinational circuit model. The depth of a prefix
 circuit is a measure of its processing time; smaller
 depth implies faster computation. The size of a prefix

 faster and occupies less VLSI area. To be of practical
 use, the depth and fan-out of a prefix circuit should
 be small. In this paper, a family of depth-size
 optimal, parallel prefix circuits with fan-out 2 is
 presented. This family of prefix circuits is easier to
 construct and more amenable to automatic synthesis than
 two other families of the same type, although the three

 abstract = "Process variations due to lens aberrations are to a
 large extent systematic, and can be modeled for
 purposes of analyses and optimizations in the design
 phase. Traditionally, variations induced by lens
 aberrations have been considered random due to their
 small extent. However, as process margins reduce, and
 as improvements in reticle enhancement techniques
 control variations due to other sources with increased
 efficacy, lens aberration-induced variations gain
 importance. For example, our experiments indicate that
 delays of most cells in the Artisan TSMC 90nm library
 are affected by 2--8\% due to lens aberration.
 Aberration-induced variations are systematic and depend
 on the location in the lens field. In this article, we
 first propose an aberration-aware timing analysis flow
 that accounts for aberration-induced cell delay
 variations. We then propose an aberration-aware
 timing-driven analytical placement approach that
 utilizes the predictable slow and fast regions created
 on the chip due to aberration to improve cycle time. We
 study the dependence of our improvement on chip size,
 as well as use of the technique along with field
 blading which allows partial reticle exposure. We
 evaluate our technique on two testcases, {\em AES\/}

The Natural Bridge of Virginia is one of the oldest tourist destinations in the United States. It's located in the city of Natural Bridge, in Rockbridge County.
Popular with Europeans in the 18th and 19th centuries, Natural Bridge and Niagara Falls were the two wonders of the new world. The Bridge has been included in several "Seven Natural Wonders of the World" lists, mostly in the 19th and early 20th centuries.
It has been designated a National Historic Landmark, a Virginia Historic Landmark, and is listed in the National Register of
History of the Natural Bridge
In 1774, Thomas Jefferson purchased 157 acres of land including the Natural Bridge from King George III of England for 20 shillings. It has remained privately owned since. Jefferson also built a two room log cabin, with one room was reserved for guests.
The Bridge served as a shot tower during the Revolutionary War. Bullets for American firearms were manufactured by dropping molten lead 245 feet from the top of the Bridge into Cedar Creek's cold water below.
In 1833, Jefferson's heirs sold the site and the new owner erected the Forest Inn to accommodate the increasing number of people.
In the 1850s Herman Melville references the Natural Bridge when describing the whale in Moby Dick: "But soon the fore part of him slowly rose from the water; for an instant his whole marbleized body formed a high arch, like Virginia's Natural Bridge..."
From _PHONE_, Civil War soldiers made ammunition in Saltpeter Cave and Lost River locations along the trail, just beyond the Bridge.
In 1927, U.S. President Calvin Coolidge inaugurates the night light presentation, The Drama of Creation.

Veasey Introduces Bill to Help Curb the Nation's STEM Skills Gap
Washington, D.C. – Congressman Marc Veasey, TX-33, introduced H.R. 6064, the Partnerships for the Future Act, to better train students in well-paying jobs in science, technology, engineering, and mathematics (STEM) fields.
Congressman Veasey's Partnerships for the Future Act would direct the Department of Labor to create a competitive grant pilot program to provide additional tools for educating and training our workforce to thrive in the 21st century workforce.
"My home state of Texas is paving the way in STEM curriculum partnerships," said Congressman Veasey. "Bell Helicopter, the Fort Worth Independent School District, and Tarrant County College have partnered to implement a curriculum for aviation and engineering programs, offering students industry certification and dual credit. It is time for us to continue this positive trend and help provide opportunities for young Americans to prepare for the jobs of tomorrow."
According to the U.S. Bureau of Labor Statistics (BLS), employment in occupations related to STEM are projected to grow to more than 9 million jobs between 2012 and 2022. Despite these trends, our nation faces a skills gap that arises from a lack of STEM skills in the workforce. Veasey's legislation would reinforce that jobs in the STEM fields are fun, and inspire our youth to thrive in today's global market.

The Endangered Aisle
Client: The Fairtrade Foundation
Farming is becoming a more unstable profession due to rising costs, volatile coffee prices and deepening climate crisis. We undertook research to understand the size of the issue - a Commodities Vulnerability Assessment and UK consumer research. Both highlighted the items at risk of becoming 'endangered' – coffee, cocoa, bananas – and the impact this may have. We needed to show the problem alongside the solution which is how The Endangered Aisle was born. A pop-up retail concept highlighting the urgent need to protect our favourite foods from climate change and give a fair deal to farmers. Stark empty shelves showcased a look into the future if we don't act now with signage confirming 'everything must NOT go'. The other side of the aisle showed the solution; shelves filled full of possibilities from coffee to peanut butter and kombucha. The immersive event brought retailers together to showcase the diverse range of Fairtrade products on the market and reiterate that together, we can make a difference. Our campaign reached almost a fifth of the UK population (17%) and as a result of seeing the campaign video, 73% believe that choosing Fairtrade products can help protect the future of our food. 69% of people who came across the campaign would definitely or be more likely to switch to Fairtrade products in the future.
