Learn how to migrate and modernize stateless applications and run them in a Kubernetes cluster.
Introduction:
Microsoft.AspNet.Identity (famously known as ASP.NET Identity) is a brand new library for asp.net membership system that allows you to build modern ASP.NET web applications. The beauty of ASP.NET Identity is that it allows you to use any storage system. There is an implementation of Microsoft.AspNet.Identity in EF provided by Microsoft. You can also find some implementation of Microsoft.AspNet.Identity by community. For example, AspNet.Identity.RavenDB andNHibernate.AspNet.Identity. Currently, the EF implementation include Roles and Claims. But sometimes, you don't need any Claims and Roles. In this article, I will show you how to implement an implementation of Microsoft.AspNet.Identity without using Claims and Roles.
Description:
First of all create a MVC 5 application. Then implement IUser,
public class ApplicationUser : IUser
 {
 public ApplicationUser()
 {
 this.Id = Guid.NewGuid().ToString();
 }
 public ApplicationUser(string userName): this()
 {
 UserName = userName;
 }
 public virtual string Id { get; set; }
 public virtual string PasswordHash { get; set; }
 public virtual string SecurityStamp { get; set; }
 public virtual string UserName { get; set; }
 }
Next we need a DbContet to store the Users,
public class ApplicationDbContext : DbContext
 {
 public ApplicationDbContext()
 : base("DefaultConnection")
 {
 }
 public virtual IDbSet<ApplicationUser> Users { get; set; }
 }
and then we need to implement IUserStore, IUserPasswordStore and IUserSecurityStampStore,
public class MyUserStore : IUserStore<ApplicationUser>, IUserPasswordStore<ApplicationUser>, IUserSecurityStampStore<ApplicationUser>
 {
 UserStore<IdentityUser> userStore = new UserStore<IdentityUser>(new ApplicationDbContext());
 public MyUserStore()
 {
 }
 public Task CreateAsync(ApplicationUser user)
 {
 var context = userStore.Context as ApplicationDbContext;
 context.Users.Add(user);
 context.Configuration.ValidateOnSaveEnabled = false;
 return context.SaveChangesAsync();
 }
 public Task DeleteAsync(ApplicationUser user)
 {
 var context = userStore.Context as ApplicationDbContext;
 context.Users.Remove(user);
 context.Configuration.ValidateOnSaveEnabled = false;
 return context.SaveChangesAsync();
 }
 public Task<ApplicationUser> FindByIdAsync(string userId)
 {
 var context = userStore.Context as ApplicationDbContext;
 return context.Users.Where(u => u.Id.ToLower() == userId.ToLower()).FirstOrDefaultAsync();
 }
 public Task<ApplicationUser> FindByNameAsync(string userName)
 {
 var context = userStore.Context as ApplicationDbContext;
 return context.Users.Where(u => u.UserName.ToLower() == userName.ToLower()).FirstOrDefaultAsync();
 }
 public Task UpdateAsync(ApplicationUser user)
 {
 var context = userStore.Context as ApplicationDbContext;
 context.Users.Attach(user);
 context.Entry(user).State = EntityState.Modified;
 context.Configuration.ValidateOnSaveEnabled = false;
 return context.SaveChangesAsync();
 }
 public void Dispose()
 {
 userStore.Dispose();
 }
 public Task<string> GetPasswordHashAsync(ApplicationUser user)
 {
 var identityUser = ToIdentityUser(user);
 var task = userStore.GetPasswordHashAsync(identityUser);
 SetApplicationUser(user, identityUser);
 return task;
 }
 public Task<bool> HasPasswordAsync(ApplicationUser user)
 {
 var identityUser = ToIdentityUser(user);
 var task = userStore.HasPasswordAsync(identityUser);
 SetApplicationUser(user, identityUser);
 return task;
 }
 public Task SetPasswordHashAsync(ApplicationUser user, string passwordHash)
 {
 var identityUser = ToIdentityUser(user);
 var task = userStore.SetPasswordHashAsync(identityUser, passwordHash);
 SetApplicationUser(user, identityUser);
 return task;
 }
 public Task<string> GetSecurityStampAsync(ApplicationUser user)
 {
 var identityUser = ToIdentityUser(user);
 var task = userStore.GetSecurityStampAsync(identityUser);
 SetApplicationUser(user, identityUser);
 return task;
 }
 public Task SetSecurityStampAsync(ApplicationUser user, string stamp)
 {
 var identityUser = ToIdentityUser(user);
 var task = userStore.SetSecurityStampAsync(identityUser, stamp);
 SetApplicationUser(user, identityUser);
 return task;
 }
 private static void SetApplicationUser(ApplicationUser user, IdentityUser identityUser)
 {
 user.PasswordHash = identityUser.PasswordHash;
 user.SecurityStamp = identityUser.SecurityStamp;
 user.Id = identityUser.Id;
 user.UserName = identityUser.UserName;
 }
 private IdentityUser ToIdentityUser(ApplicationUser user)
 {
 return new IdentityUser
 {
 Id = user.Id,
 PasswordHash = user.PasswordHash,
 SecurityStamp = user.SecurityStamp,
 UserName = user.UserName
 };
 }
 }
For password hash and security stamp, I am using the UserStore's implementation for making thing simpler. Finally we just need to change AccountController's constructor to leverage our MyUserStore implementation,
public AccountController()
 : this(new UserManager<ApplicationUser>(new MyUserStore()))
 {
 }
 public AccountController(UserManager<ApplicationUser> userManager)
 {
 UserManager = userManager;
 }
Summary:
The new Microsoft.AspNet.Identity make it very easy to extend the storage system. In this article, I showed you how to implement a simple implementation of Microsoft.AspNet.Identity. Hopefully you enjoyed my this article too.

Most Frequently Violated
Boating Laws
1. No person shall operate or be in actual physical control of a numbered
motorcraft in this state unless the person is at least 16 years of age or
is accompanied by an adult. This includes personal watercraft, i.e., jet skis,
wave runners.
2. Watercraft 16 feet and over in length shall have one approved throwable
device (ring buoy or buoyant cushion) in addition to an approved wearable
personal flotation device of a suitable size for each person.
3. All persons being towed on water skis, barefoot or other devices by a
watercraft shall wear a Coast Guard approved personal flotation device while
engaged in such activity.
4. Operators of motorboats shall ensure that a fluorescent orange flag be
displayed above the vessel anytime towed persons are down in the water,
so as to warn other boaters of the situation.
5. All watercraft operators should be aware that there are two flags used to
indicate the presence of a person engaged in diving in the immediate area.
The official flag, Alpha, which is blue and white, is internationally recognized
for all diving operations. The second flag, is the red flag with a white diagonal
stripe. No person shall operate or permit the operation of any motor powered
watercraft on the waters of the state of Wyoming within 50 feet of the display
of the above described "diver down" flag. All motor powered watercraft
approaching such flags shall do so at a no wake speed.
6. Alcohol-related boating accidents are increasing every year. Alcohol is the
number one contributor to boating-related deaths. If you are going to drink
alcohol, designate someone to operate your watercraft who is not drinking.
Wyoming Game & Fish Department officers are increasing efforts to ensure
complianceof the statute for boating while under the influence of alcohol.

With "Helping hands" and "Friendship Chains" we celebrated this International Day of Tolerance in our adopted schools across the country. In 1995, UNESCO's Member States adopted a Declaration of Principles on Tolerance, affirming that tolerance is neither indulgence nor indifference. It is respect and appreciation of the rich variety of our world's cultures, our forms of expression and ways of being human. Tolerance recognizes the universal human rights and fundamental freedoms of others. People are naturally diverse; only tolerance can ensure the survival of mixed communities in every region of the globe.
From DhokeHassue, Rawalpindi to Lasbela,Balochistan, ITA organized activities in schools, promoting the message of peace and tolerance amongst the youth of Pakistan this 16th November. These activities urged students to brainstorm and think about the various actors in their communities and the roles they all play, in search or common ground with them. The students were also encouraged to appreciate acts of kindness that they may have seen in their communities, and write them down for display at their school, reinforcing that even a small good deedgoes a long way.

Advance Trac with Roll Stabilty Control from Ford
Presenting Advance Trac with Roll Stability Control from Ford Motor Company.
- The system combines information from several sensors, including the steering wheel angle, lateral acceleration and yaw rate, to determine when the vehicle begins to lose directional control. So when you are a little overly zealous through the curves your vehicle will help save you from flipping. When the system senses wheel-slip or the loss of traction, it applies braking where needed to keep the vehicle tracking safely on its intended path. It is constantly checking your wheels something crazy like 60 times a second.
- Unlike competitor's systems, the Ford-exclusive RSC system uses a second gyroscopic roll-rate sensor to accurately measure the vehicle's roll rate. Using the roll-rate sensor, RSC can adapt the level of control to the loading conditions of the vehicle. If an unstable condition is anticipated, the system selectively applies individual brakes and modifies engine power to enhance vehicle roll resistance. Additionally, RSC uses the information from the roll-rate sensor to provide not only roll control, but enhanced side-slip control over competitors without a roll-rate sensor. This technology was launched nearly ten years ago. Ford is truly leading the way in safe SUV's. These three technologies are working together to address safe driving.
If you visit Gresham Ford on 242nd and Powell Blvd in Gresham you can see how the AdvanceTrac button on the instrument panel and how it provides the following electronic stability enhancement features for certain driving situations:
– Traction Control (TCS), which functions to help avoid drive-wheel spin and loss of traction
– Electronic Stability Control (ESC), which functions to help avoid skids or lateral slides
– Roll Stability Control (RSC), which functions to help avoid a vehicle rollover
With all this technology remember, you can't deny physics so drive safe.

The MARKUS text analysis and reading platform is a multi-faceted tool that allows users to access a range of online reference tools while reading texts in literary Chinese, and/or to tag and extract any kind of information of interest to them. In addition to names already present in China Biographical Databate and China Historical GIS, users can tag words or expressions by uploading their own lists or by using the keyword help tools.
The March 2015 release includes:
- improvements in automated markup: emperor names have been added and alternate names markup improved to reduce superfluous alternate name markup
- inline text editing: correct mistakes or add punctuation to the base text
- switching between markup modes: choose between modes from the left bar; no need to re-upload files
- new keyword markup functionality: automatically discover keywords and select appropriate ones for markup
- additional dictionaries in reading mode: trials for Buddhist and medical term dictionaries
- full Chinese language version
- links to relevant tools: starting with the newly released CBDB name/official title lookup tool
- updated and expanded help text and videos
- FAQ: for technical problems and useful markup tips
We have also added two new tools during the past three weeks: 1) The CBDB Mac Dictionary allows readers to search China Biographical Database by either using Mac OS X integrated Spotlight or by selecting any name or partial name in any software programme; 2) The CBDB Name/Title Lookup helps readers identify persons for whom only part of the name AND an official title or part thereof are known.
We continue to work on improving MARKUS and to add new tools so check back often for updates and get in touch with suggestions or to volunteer to add instructions or videos. If you are using MARKUS for research or teaching we would also like to hear about your findings.

Last Supper displays are common in almost every town and village during Holy Week but the exhibition at St. Dominic's Priory, tucked away in St Dominic Street, Valletta is special in a number of ways. Ivan Grixtri, a man who is passionate about the exhibition, the priory and the table, explains that it is the oldest Apostles' table in Malta which is what makes it unique.
The Good Friday display is not the only thing worthy of interest. The place itself is magical and acts as a site of time travel with its Baroque architecture and the historical artefacts it houses. It is during this time that the priory's huge green door is open, inviting you to step inside and discover further. "The Confraternity of the Blessed Sacrament was built just 10 years after the end of the Great Siege, making it a historical site in its own right," explains Grixti, a feature that attracts many people to walk through its doors. "Even art critics agree that its architecture is one of the most captivating," he adds.
The interior of the Oratory of the Confraternity of the Blessed Sacrament is truly breathtaking. Its walls are adorned with paintings, statues and intricate gold designs which captivate anyone who lays eyes on them. The 'Last Supper Display' itself is spectacular, decorated with candelabras, chalices and various colourful dishes accompanied by the name of the Apostle who sits in that place at the table.
Standing prominently in the centre of the room is the depiction of The Lord distributing the Holy Communion to His Apostles, painted by none other than renowned Italian artist Mattia Preti. The painting is framed and surrounded by stunning gold angels, stone clouds and the Sacrament standing proud atop the art piece.
The wooden ceiling, beautifully painted in 1711 by Alessio Erardi and depicting angels and the Sacrament, leaves a lasting impression on anyone who enters the hall. The oratory also houses artefacts linked to the Order of the Knights of Saint John and Valletta's history such as is-suġġetta (the sedan chair) which belonged to the Order's Grand Prior Fra. Bartolomeo Rull and which was later inherited by Grand Master Pinto. The oratory also contains the Virtu flag which dates back to 1734 and the glazed linen liturgical umbrella, a tool which was used during the plague by Domincan Fathers to administer the Holy Sacrament to the sick and dying.
The Last Supper Display during Holy Week not only gives visitors insight into Maltese Easter traditions, but it also contains relics from Valletta's history. It is an attraction for anyone curious about magnificent artefacts and snippets of history safely conserved inside the city's buildings and walls. These magical places and the treasures they house further contribute to our understanding of our Maltese identity and heritage. It provides us with snapshots of history and our way of life which we might not have learned during history lessons. It gives us the opportunity to travel back in time and, for a brief moment, take in the Malta and the Valletta of that period.
For some, like Grixti, the Oratory of the Confraternity of the Blessed Sacrament is not only a historical site, but also a place they are drawn to like a second home. Grixtri's grandfather, who was from Valletta, used to be the sacristan and when he fell ill, Grixti and his brother used to visit their grandparents with their mother. During that time, Grixti used to accompany his cousins to the Dominican church to help them decorate and this is where his love story with this side of Valletta started. This site of time not only tells us about our past and our identity, but it also tells the story of the community who actively takes part in its maintenance and the events that revolve around it.
What does time have in store for such a historical place? Well, Grixti has already passed down his passion to his sons, with his oldest already being quite invested in the place, so my guess is it will continue to be looked after for years and generations to come by those who hold it close to their hearts. These people will continue to preserve this time travelling site with their love and devotion.
The Oratory of the Confraternity of the Blessed Sacrament, St Dominic's Priory is in St Dominic Street, Valletta and is open to the public for the duration of Holy Week till Good Friday.

An acanthamoeba may not be a term you're likely to hear at the optometrist while being outfitted for a new prescription for contacts, but it's a good reason to heed their warnings about proper contact lens care.
The acanthamoeba is a microorganism found to essentially crawl through the eye's cornea causing not only pain but also potentially permanent blindness. The United Kindgom's Press Association recently reported though incidence if the infection is rare — only about 75 people of the 3.7 million contact lens wears in the U.K. are treated each year — it's still worth being aware of how to best avoid contracting it.
The UKPA states that the parasite, which burrows into the eye, can be picked up from a dirty case or from rinsing lenses in tap, river, pond or lake water. It also notes the condition, Acanthamoeba keratitis, is often misdiagnosed. Once contracted, treatment includes a hospital stay with "round-the-clock administration of disinfecting eye drops," UKPA states. If the infection is bad enough, the cornea could need to be replaced or blindness could also result.

Waco Scottish Rite's Gifts to Camp Success Approach Half Million Mark
October 8, 2009
WACO, TX--Donating $85,000 to Camp Success, Baylor University's summer literacy program, is only the tip of the iceberg for Waco Scottish Rite. Completely funded by Waco Scottish Rite, donations to Camp Success total nearly $500,000 over the past seven years. And the members of Scottish Rite also consistently give their time, energy and heart to the camp because they believe in the impact the program makes on each child involved.
"Camp Success made a big difference in my son's life. They've found out what things are wrong, so that we can help him. It's made him want to do work--want to read. This has given him another chance," commented Robin Reinke, a Camp Success parent.
"It allows a child to be what they can be. Our institutions are full of people who weren't given that opportunity," stated Claude Ervin, chairman of Waco Scottish Rite. "Camp Success helps them become self-sufficient people who are a productive part of the community."
The language and literacy needs in the Waco community can seem insurmountable, but Camp Success is the beginning of a solution. As of Camp Success' recent graduation, 1,074 students have graduated from Camp Success, and 204 graduate students have shared this experience.
"Camp Success changed my life. My reading was dead, but Camp Success brought it back to life!" exclaimed Caleb Jones, a third-grade student in the program.
In 2003, Camp Success began with only 24 children and now serves 80 children with a waiting list of nearly 200. Participants ranging in age from five to 18 are evaluated before camp begins to determine their specific strengths and weaknesses. Speech pathologists then develop a step-by-step plan tailored to each child.
"The impact on the teenagers is powerful," said Dr. Michaela Ritter, the director of Camp Success and assistant chair for Baylor's department of Communication Sciences and Disorders. "When you see that they were failing classes and now they're making Bs and even As and going to college--it's so rewarding."
During the four-week program, each student benefits from 50 hours of tutoring, which is the equivalent to the reading instruction provided in up to 15 weeks in elementary school classrooms. Complete with various weekly themes, a tactic designed to hold the children's interest, Camp Success is a unique program that touches lives in the Waco community.
"We're making a long-term investment in peoples' lives, and the community benefits because they will become productive, involved and self-sufficient citizens. And the school systems benefit immediately because it increases their standards and test scores," Ervin stated.
"It's not just the money. The Scottish Rite people bring doughnuts every morning for the students, they provide T-shirts for all of them and they support us by just taking the time to talk to the kids," Ritter said. "I cannot praise them enough."
Camp Success is a win for everyone: the students, the community, the school systems and even Baylor students. Baylor speech pathology graduate students serve as clinicians working alongside Baylor faculty, to earn practicum hours toward their degree programs.
"The graduate students see fast progress, and confidence soars--for both the graduate student and the child. Typically speech pathologists are with a client two times a week for one hour each time, so when the students get this intensity, they see the progress and then take the same strategies into the workforce," Ritter said.
"I've never been given the opportunity to mentor someone and actually see the results until now," explained Adam Torres, a Baylor graduate student who is a clinician for Camp Success. "It's been amazing to see them utilizing the strategies we've taught them effectively."
Scottish Rite's recent donation equipped the camp with books, supplies and faculty salaries, empowering the camp to keep touching lives. Their consistent partnership enables Camp Success, now in its seventh year, to provide free language and literacy therapy--therapy that would cost parents $7,000 to $10,000 if paid out of pocket.
"The breadth and depth of the program is immeasurable," Ervin said. "It can be whatever we want to make it--all we need is more people who have enough interest to help it forward."
Jacob Suchecki, one of the many students impacted by Camp Success, announced his gratitude, "Thank you Scottish Rite for giving us all the money so that we can get the stuff we need for success."

Sleeping with the enemy: case reports of Ornithonyssus bursa (Berlese, 1888) (Mesostigmata: Macronyssidae) causing human dermatitis in Brazil
Appears in Collections:
Ornithonyssus bursa, known as the "tropical fowl mite," is a hematophagous mite of domestic and wild birds, which occasionally bites humans. Accidental bites on humans occur mainly when abandoned bird nests are close to homes or when people are handling parasitized birds. In the present study, we describe five case reports of bites on humans and new records of localities for this species. Based on the material examined, we provide morphological and molecular characterizations for this species herein.

Numerical Simulation of Zeolite- and V-Based SCR Catalytic Converters
A numerical model describing the ammonia based SCR process of NOX on zeolite catalysts is presented. The model is able to simulate coated and extruded monoliths. The development of the reaction kinetics is based on a study which compares the activity of zeolite and vanadium based catalysts. This study was conducted in a microreactor loaded with washcoat powder and with crushed coated monoliths. A model for the SCR reaction kinetics on zeolite catalysts is presented. After the parameterization of the reaction mechanism the reaction kinetics were coupled with models for heat and mass transport. The model is validated with laboratory data and engine test bench measurement data over washcoated monolith catalysts. A numerical simulation study is presented, aiming to reveal the differences between zeolite and vanadium based SCR catalysts.

Climate Witness: Pak Azhar, Indonesia
I have been living in Balikukup since 1999. Balikukup is a small island of 18 ha consisting mainly of sandbanks. However, the island's size is not fixed as it depends on the tides. During low tide, a large sandbank is exposed, extending 1 km towards the sea.
The weather is a significant factor in the work of a sea cucumber fisherman
I started collecting sea cucumbers in 2001. There are 2 ways to catch sea cucumbers; some fishermen just search on the beaches around the island during low tide at night, while others dive underwater, down to depths of 10 m.
Sea cucumber fishermen are highly dependent on the weather to do their job. Fishermen cannot catch good harvests during rainy or stormy weather, as sea cucumbers hide underneath the sand during that time. Therefore, it is important for a sea cucumber fisherman to predict what the weather will be like before going to work.
Usually I observe the weather at dusk or in the early evening to predict whether it is going to rain or be stormy at night. But nowadays, it is getting harder to predict the weather accurately. For example, early evening yesterday I predicted that there would be no rain at night, but around midnight and early morning heavy rain came down.
In the old days, we fishermen could predict the weather. But not anymore. The elders on our island also mentioned the same thing. Since 2002, Atang, one of the fisherman elders whom we regard as the best expert in predicting the weather in Balikukup, said that the weather was getting unpredictable. Before, Atang could produce a very good prediction, even for the course of a full year.
'Bulan janda' or Widow month
One example of unpredictable weather is the gone phenomena of 'bulan janda', or 'widow month'. It is called widow-month because when the fishermen went to the sea during the event, they rarely came home safely. Thus, their wives became widows. Widow month is an annual event when the wind blows very strongly for 44 days from the south. This wind stops for a short period of time (half an hour), and then goes back to blowing very hard. During that time it is impossible for fishermen to go at sea.
Fishermen who had saved enough money and food supply did not need to go at sea during 'widow month' because the conditions were too dangerous. However, other fishermen had no other option but to go to sea during the event.
The phenomenon of 'widow month' does not exist anymore. The last time it happened was in 1991 according to fishermen. After 1991, during the supposedly 'widow-month', there could be calm periods for up to 2 weeks. None of the fishermen understands why the 'widow month' phenomenon has slowly disappeared.
No clue when money will come
The unpredictable weather is a disadvantage for us fishermen because we no longer know when we can go fishing. It is difficult for us to predict when we will make money. Before, we could estimate when was the right time to make income and put some money on the side, as we could predict when we can go fishing. Now, whenever we have good weather, we just go fishing. We can no longer make financial plans.

Scientific reviewReviewed by: Dr Heru Santoso, Project Coordinator of the TroFCCA (Tropical Forests and Climate Change Adaptation) project, Indonesia
The witnesses told three natural phenomena that they considered climate related. They are increased land erosion, higher tides and unpredictable weather. Even though non-climatic factor could contribute to these phenomena, for example an increase in land erosion could be due to land mismanagement, or a higher tide could be the subsequent of regional subsidence, etc. However, in all three different locations the people observed an increase of wave energy and increasing unpredictable weather that could affect the sustainability of their villages and their livelihood.
There are very few scientific literatures to report whether the observed phenomena in this specific region are related to climate change. This region is open to Sulawesi and Sulu seas as flow paths of oceanic current from the western Pacific Ocean to Indian Ocean. Higher tides in Berau area could be related to the increase of sea surface level in the western Pacific during La Niña events. This phenomenon recently has become noticeable than in the past probably because global warming has accentuated the extent of this climate mechanism (Mimura et al. 2007).
For the same reason, unpredictable and abrupt change of weather has become noticeable. Abrupt changes are usually associated with high wind speed which could only happen if there is a significant difference in pressures between two areas. Striking heat, in particular over a heat sensitive land area, under a warmer condition could generate this high pressure difference quickly. Land sensitivity to heat is higher if the forest cover has gone or heavily degraded. The 'widow month', a regular phenomenon of strong southerly wind that has been disappearing, is normally associated with the monsoonal trade wind in which the easterly wind from eastern Indonesia turn northward to Asia. Global warming or higher regional temperature could alter the distribution of regional or subregional energy concentration and could also alter the scale and extent of circulation.
Therefore, global warming could have contributed to the increasing trend of recurrences of natural phenomena as reported by witnesses. However, it is quite proper to verify whether this global warming has accentuated climate mechanisms in this subregion by comparing with other climate variables. For example, during La Niña events warm waters from the east flow to the west and usually bringing more rains. The high tides in the Berau region which could be explained by this mechanism could be verified with rainfall data during that particular time of the events, preferably with a long period of observation data.

Michaela deputy has controversial start at his new school
Barry Smith
Barry Smith, deputy headteacher at Michaela Academy for three years has had a rough start in his new job as principal of the former Great Yarmouth High School, now relaunched by Inspiration Trust as Great Yarmouth Chartered Academy.
Smith has hit local and national headlines as a result of importing Michaela methods into a school with its own ethos and history, rather than a brand new free school as Michaela was.
Parents admit that things were not perfect at GYHS but some are objecting strongly to the school rules and disciplinary methods as well as the tone of Smith's communications, written and verbal, with parents.
Parents have set up a Facebook page 'Yarmouth High Worried Parents' which currently has more than 1,000 members. A fascinating exchange of views is taking place on the page which cover the specific rules and their implementation but go wider to look at the rights of children and parents. At present pupils are also making contributions on the page and opinions vary with some welcoming the 'calm' that the rules bring and others finding themselves at the receiving end of the demerits. Similarly some parents are keen to challenge, if not the rules, the way they are being implemented. Parents with children with special needs are concerned about whether their child will be able to follow rules such as 'tracking the teacher' where every child has to have his or her eyes on the teacher throughout the lesson. Children on the autistic spectrum often have a problem with making and maintaining eye contact.
The local authority has set up and investigation into the school's exclusion policy which had not been updated to reflect recent DfE guidelines LINK
Tomorrow parents are to meet with Mr Smith. It should be interesting.

Does "tracking the teacher" apply to practical lessons like chemistry? I can foresee "health and safety" problems if it does!!!

'Parents are to meet with Mr Smith.'
According to the BBC East news website, a spokesman for the Inspiration Trust said: "The academy will be holding a meeting for all parents in the coming days so they can hear first-hand what Great Yarmouth Charter Academy is really all about."
They don't just bully the pupils, they try to brain-wash their parents as well! Will they succeed?
The BBC report includes this from a parent about Barry Smith:

I saw a report a while ago that Michaela got an 'outstanding' from Ofsted. I assumed that this was inevitable as it's a 'free' school and Birbalthingy was Gove and the Tories' darling. Apart from the crap nature of Ofsted inspections, Ofsted people would know that an 'outstanding' was what was expected of them and to deny the Birb one would be like failing to clap and burst into tears of joy when Kim Jong-Un walks into the room.
I certainly hope I'm right. I'd hate to have to question my prejudices. Can anyone enlighten me?

ARCA to perform first flight of aerospike engine at Spaceport America
LAS CRUCES - ARCA Space Corporation has announced the first test-launch of its Demonstrator 3 space vehicle at Spaceport America in August. This will mark the first space flight of an aerospike rocket engine.
Aerospike rocket engines are described as significantly more fuel efficient than the current engines and could make launches attempting to bring satellite payloads to space more affordable.
Demonstrator 3 will perform a suborbital space flight up to an altitude of 100 kilometers above the New Mexico desert.
In March, ARCA introduced the Haas 2CA, a single-stage-to-orbit rocket equipped with the Executor Aerospike linear rocket engine. The rocket was developed in ARCA's Las Cruces facility.
The Haas 2CA is an orbital launcher aiming to operate on the small satellite market, estimated by Space Works and Eurostat at $5.3 billion over the next decade. Ground and vacuum tests will be conducted at White Sands Test Facility in conjunction with NASA. ARCA hopes to gain more data before the launch of the Haas 2CA, which is scheduled for 2018 from NASA's Wallops Flight Facility in Virginia.

→ Peruse the Letters Archives(Added 25 December 2008)
Until 1928, the Canadian Artists Series Christmas cards were printed with the Dell'Aqua process, giving them the stylized graphic appearance shown in preceding Leisure Letter postings. This process was expensive because of the labour required for hand-colouring. After 1929, because of the onset of the Depression, Rous and Mann, Ltd. reverted to the more economical letterpress process of printing where both black and coloured ink were applied to a relief image. Examples of cards by artists from this later era can be distinguished by their uniform borders and resemblance to serigraph oil paintings, such as this card by Paul Caron. The change in appearance of the cards coincided with the diminishment of their sales. This could have been due to their new look, but was also certainly a result of the Depression, which reduced the population's expenditures on items potentially considered frivolous, such as Christmas cards.

Gap Effect on Performance of Podded Propulsors in Straight-Ahead and Azimuthing Conditions
Abstract:This paper presents results of an experimental study on the effect of gap distance on propulsive characteristics of puller and pusher podded propulsors in straight-ahead and static azimuthing open-water conditions. The gap distance is the axial distance between the rotating (propeller) and stationary (pod) parts of a podded propulsor. The propeller thrust and torque, unit forces, and moments in the three-coordinate directions of a model podded unit were measured using a custom-designed pod dynamometer in various operating conditions. The model propulsor was tested at the gap distances of 0.3%, 1%, and 2% of propeller diameter for a range of advance coefficients combined with the range of static azimuthing angles from +20° to 20° with a 10° increment. The tests were conducted both in puller and pusher configurations in the same loading and azimuthing conditions. In the puller configuration, the gap distance did not have any noticeable effect on propeller torque in straight course condition, but had an effect in azimuthing conditions. The propeller thrust and efficiency were also influenced by the change of gap distance, and the effects were more pronounced at high azimuthing angles and high advance coefficients. For pusher configuration, however, the gap distance did not affect the propeller performance characteristics in straight-ahead and azimuthing conditions. Both in straight course and azimuthing conditions, the unit thrust and efficiency were not influenced by the gap distance in either puller or pusher configurations. The gap distance had a noticeable effect on unit transverse force and steering moment both in puller and pusher configurations, and both in straight course and azimuthing conditions. An uncertainty estimate of the measurements is provided at the end.

New white paper on PDF for archiving standard
DocsCorp has published a new whitepaper on the topic of PDF for Archiving: Everything you need to know in plain, simple English as government and industry bodies worldwide increasingly adopt the standard. This year in the United States will see the Courts move to mandate the filing of case documents with the CM/ECF (Case Management/Electronic Case Files) system in PDF/A.
The PDF/A Competence Center, a non-profit association of more than 110 organizations and individual experts from 20 different countries dedicated to promoting the exchange of information and experience in the area of long-term archiving of documents, describes the standard as follows "PDF/A has been accepted by the International Organization for Standards (ISO) as the standard for the long-term preservation of documents. The standard does not define an archiving strategy or the goals of an archiving system. It identifies a profile for electronic documents that ensures the documents can be reproduced exactly the same way in years to come. A key element to this reproducibility is the requirement for PDF/A documents to be 100% self-contained. All of the information necessary for displaying the document in the same manner every time is embedded in the file."
The aim of the DocsCorp whitepaper is to explain the reasoning behind the standard and how it is different from a normal PDF with as few acronyms and as little jargon and technical explanation as possible. More specifically, the paper answers these frequently asked questions:
1. What is PDF/A, and how is it different from a non-PDF/A document?
2. How do I know if a document is PDF/A compliant?
3. How do I create a PDF/A document?
4. Is there a way to make documents PDF/A ready, without actually converting them to PDF/A?
5. Should I implement these changes to existing PDF workflows?
6. Should I be converting every document to PDF/A now?

We present a theoretical investigation of self-focusing in a hollow waveguide filled with noble gas. Our analysis was performed for a laser pulse that was predominantly in the fundamental mode and revealed the physical processes involved in self-focusing in a hollow waveguide. A critical power for self-focusing was obtained that was found to be substantially higher than the critical power for self-focusing in a bulk medium. Useful design criteria for pulse-compression systems are presented. We identify the parameter range for which the transverse variation of the pulse phase introduced by the Kerr nonlinearity is small.

text: Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF's need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evaluated to perform CO2/CH4 separation through adsorption. The adsorption capacity of pure carbon dioxide from methane was measured in a magnetic suspension balance between temperatures of 308 and 373 K up to a pressure of 700 kPa. The evaluated material presents higher adsorption capacity than previously studied shaped samples with a carbon dioxide and methane adsorption capacity up to 3.07 and 0.63 mol/kg at 100 kPa and 308 K respectively. Moreover, the experimental data were fitted with the Langmuir model. Isosteric heats of adsorption were obtained to be 22.8 and 15.1 kJ/mol for CO2 and CH4 on Cu-BTC tablets respectively, which indicates a strong adsorption of carbon dioxide on these adsorbents. Also, single and binary breakthrough curves were measured in the same temperature range and atmospheric pressure by using Cu-BTC tablets as the adsorbent. The preferential adsorption capacity of CO2 on nanoporous copper trimesate (Cu-BTC) indicates that this material can be used for methane purification from natural gas.

Thermotreated wood. Thermotreatment
Thermotreated wood is manufactured under controlled heating conditions at temperatures of 170…230 degrees C. The degree of heat depends on what type of wood is being processed and what type of characteristics are desired. The process involves no chemicals or addatives. Since the only outside agent used is moisture, we can proudly claim this to be natural product. During the thermotreatment process, the cellular structure changes. The hemicellulose starts to break down and pitch in coniferous woods evaporate.
During the thermo treatment, the following changes occur:
 1. Colour changes from light to dark brown
 2. Deformation due to moisture variations decreases by 50-90%
 3. Equilibrium moisture content lowers
 4. Thermal conductivity decreases by 0-30%
 5. Overall heat-transfer coefficient k improves
 6. Bending strength decreases by 0-30%
 7. Elasticity decreases, but rigidity increases
 8. Wear resistance improves
 9. Wood becomes lighter in weight
 10. Biological durability improves
 11. Pitch evaporates
 12. Dead knots fall out
 13. Cellular structure changeswood „ages" structurally
As it appears from above, thermotreatment offers a quite good opportunity e.g. for the carpentry industry to produce environment-friendly wood products of a new kind of structure.


Cypress: The Wood Eternal

There is frequently a wide variation of color with one shade
usually predominating in a given locality. For instance, the prevailing
type found in the deep swamps of the St. Johns River is amber, referred
to as yellow cypress, while that growing on the fringe or shallow swamps
of the St. Johns is decidedly darker and possessed of stronger grain. The
typical amber wood of the Apalachicola and other alluvial river swamps
occasionally gradates to dark brown or chocolate and when cut often
presents dark stripes on a lighter background.
Trees that show the dark-red bands of the heavier summerwood,
especially in the lower Mississippi River delta, are known as red cypress.
Wood from the northern regions is referred to as white cypress. In
southern lumber camps, logs that float high are also called "white"
regardless of actual color. In lumber camps along the Atlantic coast,
heavy wood which sinks or floats very low is called "black" while in
Gulf region the term refers more to color than buoyancy. Dark cypress
frequently is no heavier than lighter shades of the wood.
When thoroughly seasoned, cypress wood weight on an average
of about 28 pounds a cubit foot. It is considerably heavier than
redwood, spruce, and most cedars. The specific gravity green cypress
generally varies from about 0.80, or 50 pounds, a cubit foot to 62.35, or
the same weight as water, although it is often much lighter than this.
When dried it is sometimes found as light as cork and is frequently used
for floats on fishing nets.

Abstract The paintings in White Noise are a response to temporal lighting conditions that occur at night. A discussion of sensory affect demonstrates how perception is inextricably connected to the body's sensory capabilities such as sound and touch. By examining Maurice Merleau-Ponty's theory of phenomenology and looking at Gestalt Psychology based experiments it is made clear that seeing whole and complete forms in the world is a product of embodied perceptual experience. I recall early experiences of being affected by light describing the optical illusion of the afterimage and then move into the everyday perceptions that inform my current painting practice. The painting studio process is examined as a beacon from which to reconcile the affecting nuances of observed lighting at night. I discuss the importance of allowing trial, error and patience to take place while making paintings to in turn seek out optimal colour relationships and shape interaction. By developing a specific painting vocabulary that responds to the colour, texture and sound associated with perceptual experiences I reconcile through the abstract process of painting how affecting experiences can be re-presented and reinvented onto the canvas.

The Artistry of Seedbox
Winter is the perfect time to see Seedbox (Ludwigia alternifolia) in fruit, and to understand how this plant got its name.
Seedbox (Ludwigia alternifolia) with fruit capsules
Attached along the length of the standing stems of this plant are fruit capsules that look like perfectly carved wooden boxes, each with a convex top and rounded bottom, and with elaborate designs that appear to be carved on the cube's lid.
Seedbox (Ludwigia alternifolia) fruit capsules
These tiny decorative fruit capsules are often visible throughout winter, releasing the many tiny seeds inside through a pore on the top of the box, and eventually also by splitting open at the seams. Before the fruit capsule opens, the seeds may rattle, giving this plant another common name, Rattlebox.
How is this perfectly shaped fruit capsule produced? Who is responsible for the beautiful carvings on the lid? (Could it be tiny flower elves? Maybe there is a less magical explanation.)
Seedbox typically blooms in mid to late summer, usually July and August. Let's look at the flowers and buds for an explanation.
Seedbox (Ludwigia alternifolia) in bloom
In Seedbox buds, sepals are the outermost layer of flower parts. They are green and leaf-like, and play the role of bud scales, enclosing and protecting the other parts of the flower before it opens. The photo below shows a flower bud, enclosed by the sepals. In the upper right of the photo, there is a notch in the sepals at the base of the bud, a narrowing of the structure, and a squarish impression in the leafy covering. This covering is enclosing the flower's ovary, the flower part destined to become the fruit capsule. We can see two sides of the ovary, already hinting at the box-like fruit capsule to come.
Seedbox (Ludwigia alternifolia) flower bud. In the top right corner, note the square ovary with a leafy covering at the base of the bud. The ovary will become the fruit capsule; its square shape is already in place.
The purpose of the flowers is to attract visitors to assist with cross-pollination. The most effective pollinator will have a tongue long enough to reach the nectaries on the face of the ovary below, while brushing its body on the flower's reproductive parts, including the Sweat Bee in the photo below, and some Bumble Bees. Other bees and beetles are known to visit the flowers for nectar and pollen, while flies, wasps, and butterflies only partake of the nectar.
Seedbox (Ludwigia alternifolia) flower with a visiting Sweat Bee. Her tongue is long enough to reach the nectaries while her body brushes against the flower's reproductive parts, dropping off and picking up pollen.
The bee is rewarded for her pollination assistance with nectar and pollen for herself, and she will also carry some back to provision her nest for her larvae.
Seedbox (Ludwigia alternifolia) flower with a visiting Sweat Bee. Notice the pollen she has packed on her hind legs to bring back to her nest for her larvae.
Let's look at an open flower.
Seedbox (Ludwigia alternifolia) in flower.
Working from the outer ring of flower parts layer by layer towards the center, each flower has four sepals, four yellow petals, four stamens (male reproductive parts) and one pistil (female reproductive part). The pistil consists of a stigma at its tip, where the pollen must be deposited in order for pollination to take place, the style, which positions the stigma and through which the pollen must travel to get to the ovary, which is at the pistil's base. Seedbox stigmas look like miniature pompoms perched at the top of their pedestal-like styles. As the ovary ripens to a fruit capsule, if the pollen successfully reaches and fertilizes the ovules in the ovary, seeds will be produced.
Seedbox (Ludwigia alternifolia) in flower. The green sepals are peeking out from behind the yellow petals. The petals, stamens and style of the pistil are attached to the top of the ovary, while the sepals are appressed to the four sides of the ovary.
If we look at the very center of the flower, we can see the petals, stamens and pistil attached to the square top of the ovary, with the sepals appressed to the four straight sides around the ovary's outside edges.
The flower parts that made pollination possible eventually wither and drop off, leaving their mark on the face of the ripening fruit capsule.
The petals drop off after about a day, leaving tiny scars that can be seen at each corner of the developing fruit capsule's topside. As the stamens drop off, each leaves a mark midway between the corners, just slightly in from the edge of the square.
Developing Seedbox (Ludwigia alternifolia) fruit capsule. Notice the scars left by the petals and stamens which have withered and dropped off. The stigma, style and sepals are still present.
Eventually the pistil's stigma and style, positioned at the center of the flower above the ovary, drop off, leaving a round scar as a reminder of their role in the flower's reproduction strategy.
Developing Seedbox (Ludwigia alternifolia) fruit capsule. The stigma and style have dropped off. The sepals are still present.
Finally the sepals are gone, leaving the bare woody 'seedbox'.
Seedbox (Ludwigia alternifolia) fruit capsules
The face of a Seedbox fruit capsule records the history of its pollination story. The four large-ish evenly spaced ovals in each quadrant on the top of the fruit capsule were the nectaries, the source of the beverage that enticed the flower's visitors.
Seedbox (Ludwigia alternifolia) fruit capsules. The scars from the petals and stamens are visible near the edges of the fruit capsule's top, the round scar in the center marks the spot where the style was attached, and the four ovals are the flower's nectaries.
Seedbox prefers moist soil, and can be found growing in wet meadows, prairies and woods, as well as in drainage ditches. It is native in Quebec and Ontario provinces in Canada, and in the United States from Vermont west to Wisconsin, southwest to Colorado, then south as far as Texas and the Florida panhandle. It is a member of the Evening-primrose (Onagraceae) family.
If you're looking for something to do while waiting for spring, look for Seedbox!

 1. Thank you Mary Ann for this post. In the fall of 2019 I purchased some Ohio ecotype seed, there was a mix up and I ended up with this little beauty! How fortunate is that? I saved the plants, but since I really didn't know anything them I decided understanding what makes them tick would be one of my 2020 winter projects! Your post has been a wonderful place to start!
 2. Wow, wow, wow. Amazing illustration of the complexity and beauty of this unusual plant. Thank you Mary Anne. You are a treasure!!!
 3. Mary Anne, this is a wonderful illustrated essay on the Seedbox! I have a small collection of perfect little boxy seeds and I hope to be able to grow the plant in my garden this year. I think I'll keep a few of the seeds just to look at, though…
 4. Thank you for yet another beautiful and informative lesson in nature's beauty and bounty. I am also going to look for seedbox near me!
 5. Mary Anne thank you for this wonderful article. I have a few stems of the seed pods of Ludwigia alternifolia on my desk because I think they are tiny works of art. And now I know how they became so beautiful.
 After reading your article I became curious about the genus name Ludwigia. I learned that Christian Gottlieb Ludwig was a prominent German botanist and physicist and was a strong critic of Linnaeus and his new system of plant classification. So to exasperate Ludwig, Linnaeus named a genus after him. (This was apparently a punishment Linnaeus sometimes bestowed on his critics.)
 Happy ending though – Ludwig eventually came around to Linnaeus' way of thinking!
 6. Happy Leap Year, Mary Anne. I loved the mystery with the excellent build-up to the solution complete with magnificent photos. I am going out to look for a seed box. This is a wonderful gift for this last day in February.
 7. Thanks so much for this wonderful explanation! I'm not sure I've ever noticed this plant. I'll have to keep an eye out for it.
 8. Mary Anne–
 What a remarkable flower! I've never been able to follow how this amazing seed capsule develops from the rather insignificant flower, and you've revealed the mystery to me. Your photography is beautiful. Thank you for teaching us about this charming plant =)

Helium-3 (3He) is a necessary component of many nuclear detection devices; however our country is facing a Helium-3 shortage. To address this shortage, DHS' Domestic Nuclear Detection Office (DNDO) is advancing the search for efficient, cost-effective alternative technologies.
After weeks of rigorous testing, DNDO completed a test campaign for alternative technologies to smaller Helium-3 dependant radiation detection systems. During the test campaign, conducted at the Radiological and Nuclear Countermeasures Test and Evaluation Complex at the Nevada National Security Site, DNDO evaluated 39 different neutron detection technologies, such as handhelds, backpacks and vehicle-mounted equipment.
DNDO provided post-test information to participating vendors to help accelerate device development. These technologies are being developed through government-sponsored research or by commercial manufacturers, expediting product development while reducing government cost.
In August 2011, DNDO successfully completed a two-year effort to find replacement technologies for the 3He neutron detectors in Radiation Portal Monitors (RPMs), identifying three replacement alternative 3He technologies which are now used in commercial production.
DNDO works in collaboration with the private sector to anticipate shortages of important resources such as Helium-3, to ensure the country's capability to protect against potential radiological and nuclear threats.

The sphragis of Heliodoros, genealogy in the Aithiopika, and Julian's Hymn to King Helios.
This article analyses the final sentence of Heliodoros's Aithiopika as a sphragisan autobiographical statement by the author. Heliodoros here stresses his descent from Helios, as one of characters in the romance, Persinna, also does. However, while genealogy (or physis) is an important element it is counterbalanced by the relativization of knowledge in the Aithiopika - nomos is king. The tension between these concepts is resolved by reading the romance in the light of Julian's Hymn to Helios.

Revisiting the Greed and Grievance Explanations for Violent Internal Conflict
Author: Syed Mansoob Murshed, Mohammad Zulfan Tadjoeddin
Access full text: available online
This Journal of International Development article assesses two recent explanations for the onset of internal conflict: greed and grievance. The former reflects elite competition over valuable natural resource rents. The latter argues that relative deprivation, and the grievance it produces, fuels conflict. However, this article argues that neither the presence of greed or grievance is sufficient for the outbreak of violent conflict. Violent conflict requires institutional breakdown, or the failure of the social contract.
Pure versions of the greed hypothesis are, on their own, unsatisfactory explanations for the causes of conflict. In reality the competing greed versus grievance hypotheses may be complementary explanations for conflict. The greed explanation for conflict duration and secessionist wars works in cross-country studies, but has to make way for grievance-based arguments in quantitative country case studies. Grievances and horizontal inequalities may be better at explaining why conflicts begin, but not necessarily why they persist. Neither the presence of greed or grievance is sufficient for the outbreak of violent conflict, something which requires institutional breakdown, which we describe as the failure of the social contract.
The breakdown of the social contract captures institutional malfunctioning and it is also crucial in transforming grievances into collective violence. A failing social contract may be the real signal of the risk of civil war.
- In certain instances, where there are substantial quantities of natural resource wealth, greed may be the dominant factor prolonging conflict, but without group formation (for which some historical grievances are important), violent collective action cannot take place.
- Some societies, despite having conditions pre-disposing them to civil war, such as horizontal inequality, polarisation and natural resource rents, do not descend into conflict.
- For the forces behind either greed or grievance to take the form of large-scale violence there must be other factors at work, specifically a weakening of the 'social contract'. This is similar to the weak state capacity, and by implication poor institutional quality.
- Even if rents from capturable resources do constitute a sizeable prize, violent conflict is unlikely to take hold if a country has a framework of widely agreed rules.
- Such a viable social contract can be sufficient to restrain, if not eliminate, opportunistic behaviour such as large-scale theft of resource rents, and the violent expression of grievance.
The degradation of the social contract is more likely in the context of poverty and growth failure.
- As yet, no empirical models at the level of cross-national analysis exist to properly test for the relative power of greed vis-a-vis horizontal inequality type grievances in explaining conflict onset.
- Greed and grievance can and do co-exist; because one breeds the other a model of their simultaneous determination is required, along with the contribution of poverty (which is chiefly about the lack of growth) and institutional quality.
- Furthermore, the existing econometric literature regarding the causes of conflict allows us to infer little about the true nature of the causal links between the phenomena examined.
- The most robustly significant predictor of conflict risk and its duration is some indicator of economic prosperity. At a higher income people have more to lose from the destructiveness of conflict; and higher per-capita income implies a better functioning social contract, institutions and state capacity.

HERITAGE: Extensive restoration work to Fort George will cost $2.75 million
Fort gets facelift
Niagara-on-the-Lake's most recognizable War of 1812 site is getting a major $2.75-million facelift.
Extensive restoration work of the 80-year-old replica of Fort George started about three weeks ago.
The project, the biggest in the national historic site's history, will stabilize the crumbling structure.
Six large bastions, or cannon platforms, and sections of decaying palisade, or wooden fence, are being replaced to strengthen the outer walls of the fort.
That work alone will cost taxpayers $2.5 million.
More reconstruction work -- roof and siding replacement -- will be done on buildings inside the fort walls.
Geoff Hancock said the restoration of the tourist attraction could have waited a few years, but the upcoming bicentennial events moved up the deadline.
Parks Canada was also able to benefit from the federal government's major infrastructure economic stimulus cash pool.
Until now, repairs to the fort have been done on a much smaller scale, said Hancock, Parks Canada's project leader for the War of 1812 bicentennial.
"This is a much bigger scale," Hancock said.
"This is sort of getting your 'if we can do it all in a year, year and a half, what can we do?' scenario. This is what happened."
Built in the 1930s, the fort was designed to look exactly like the military hub erected by the British in 1802 to defend the borders of Upper Canada against the Americans.
It was designed to control supplies coming through the Niagara River, which was crucial to the survival of all forts west of the region.
The giant hexagonal wooden structure was given even greater importance during the War of 1812 when it served as the headquarters for the Centre Division of the British Army.
Major General Sir Isaac Brock was stationed there and led a force of British soldiers, local militia, aboriginal warriors and a corps of free slaves.
Roger Armstrong of Rankin Construction said he recognizes the historical significance of the site to both Canada and Niagara.
The estimator/project manager said it's great to be part of such an important local project.
Three archeologists are working alongside eight to 10 construction workers to look for historically significant artifacts as they dig.
"It is unique," Armstrong said. "We may never have the
opportunity to do a job like this again."
Hancock said the bulk of the work on the Niagara Parkway site will be done by May -- in time for the start of the tourist season.

Skills required of security guard jobs
A security job is a job that requires many more skills than is apparent from watching a security guard man a desk.
As a security guard, you will use your skills to prevent situations from occurring. If one does occur, you'll soon find yourself using an even broader array of physical and mental skills as you deal with trespassing and other irregularities.
Communication Skills
Security guards must be able to communicate with others in a clear and concise manner both verbally and in writing. You will use verbal skills in many situations.
You will likely use a two-way radio to communicate with other guards and need to communicate in a professional manner. It is also necessary to be able to tell trespassers to leave the property without escalating the situation.
Some security positions require that the phones be answered, which requires good phone skills. According to the United States Department of Labor's Bureau of Labor Statistics, security guards "also may interview witnesses or victims, prepare case reports, and testify in court."
Written skills will be used daily. At the end of the work shift, many security guards are required to log the activity during that shift.
This information needs to be written clearly, as guards on the next shift will need to be able to read it in order to keep up to date.
You'll also need to write reports concerning any incidents that have occurred on your shift. These reports will be seen by your supervisor and, as with any irregular situation, could be subpoenaed as court documents.
As with any job, you'll need to be able to communicate effectively with your supervisor and coworkers.
Observational Skills
You'll need to be able to spot any irregularities around the property, such as unlocked windows or unauthorised persons. You also may be required to catch out-of-the-ordinary events on closed-circuit TV cameras.
Physical Skills
Many security jobs require making rounds of a property on a continual basis or standing guard at a particular station. You'll need to be able to stand and/or walk for long periods of time. Should a trespasser need to be apprehended or physically removed from the property, you'll need to have the strength to do so.
The job may also require the carrying and potential use of a firearm, which will require excellent fine motor skills and eyesight.
Technical Skills
You'll most likely be using a two-way radio, and may be required to use a computer to enter your daily logs.
Your position may also require the use of a photocopier. If firearms are carried, you'll have to prove your ability to use them effectively by passing a firearms training course prior to your employment.

This technique is adapted from author Jonathan Goldman. He says that simple, self-created vocal sounds such as elongated vowels like "ah", "oh" or even an "mmm" humming sound can have profound and positive effects on your physical, mental and emotional states.
For example, Goldman says these sounds can:
1. Calm your nervous system, lower blood pressure and heart rate, and can reduce levels of stress-related hormones such as cortisol.
2. Increase melatonin, a hormone which helps us sleep at night.
3. Release endorphins—those self-created "feel good" brain chemicals.
Feeling stress or anxiety? Take a nice deep breath and sound forth with an "ah" a few times….or just hum for a minute or two. No one will hear you but you'll feel a lot more relaxed almost instantly.

3 September 1998 Characteristics of contrast and application for small-target detection

Abstract
The detection of small targets, especially of a target within a single frame of data, is an important problem in image processing. A lot of work have already been proposed for this problem. Of them, nonlinear morphology-based methods have shown their advantages than traditional linear methods in target detection. Many of these methods are based on local background estimate and threshold computation. A thresholding procedure is required for the methods. However, none of them shows how to get an appropriate threshold and what is the relation between a threshold and the detection performance of the detector. In this paper, we use the contrast between target and local background to be the measurement of characteristic of targets and background. Here, the contrast between target and local background is the ratio of target residual, which is acquired by subtracting local background estimate from the original image, and local background estimate. By analyzing the difference between the contrast between target and local contrast between background and local background, we can determine an appropriate threshold which can achieve high probability of detection while produce very small probability of false alarm. Experiments on a large read sea- surface ship images prove the effectiveness of the method presented in this paper.

Command syntax summaries
A syntax summary is a comprehensive list of the adapter-specific commands organized for use with data sources and data targets. Syntax notation, as applied to all command documentation, indicates required and optional commands, as well as options available for each command.
Required commands appear at the beginning of the list. Optional commands appear in brackets [ ]. Command dependencies are also noted when commands appear on the same line.
The following is a portion of the syntax summary for the IBM® MQSeries® messaging adapter command available for use with data sources:
-QMN queue_manager_name
-QN queue_name
This example illustrates that both the Queue Manager Name adapter command (-QMN) and the Queue Name adapter command (-QN) are required for data sources. In this example, you may use the Queue Manager Name adapter command (-QMN) to specify the name of the queue manager on which the queue (specified by the -QN command) exists.
The following is an additional example of the syntax notation used by the IBM® MQSeries® messaging adapter:
-QMN queue_manager_name
-QN queue_name
[-MID message_ID|-HMID hex_message_ID]
This example illustrates the use of brackets to indicate optional message ID adapter commands. The brackets [ ] indicate that both of the message ID commands are optional. The pipe | indicates that you may choose one of these commands, but not both.
In this example, you may use the Message ID adapter command (-MID) to specify a particular message ID for a data source. Or you may choose to use the Hex Message ID adapter command (-HMID) to specify message identifiers using hexadecimal pair notation.
* The File and Sink adapters do not require any adapter commands for their operation. The File adapter uses only the full pathname and filename for a parameter.

Compassion: A Shared Value and A Common Project
By Anindita N. Balslev from The Global Spiral.
"When scholars approach a vital human emotion and shared value like compassion, they are confronted with a range of questions. First, how do we understand compassion? How has it been analyzed and interpreted in the cognitive discourses that are associated especially with the world religions? Next, why is this value generally recommended by religious and moral traditions across the board?"

The feasibility of square-pulsed thermography nondestructive testing for the detection of defects in one ceramic material sample has been carried out by finite element (FE) analysis. In particular, a ceramic plate containing defects of different diameters, depths, locations, nature, and shapes has been numerically investigated by means of Comsol® Multiphysics computer program, taking into account the results coming from both a MATLAB™ script and the infrared thermography (IRT) technique. Indeed, the FE method simulates through a 3D model the heat transfer process induced into the ceramic material by two halogen lamps that have been applied in order to provoke an optimum thermal stress. Moreover, further defects like cracks arose beneath the surface of the plate due to the shrinkage process, have been discovered, and contrasted using a non-usual segmentation algorithm that when correlated in the time to IRT data simulates the thermo-elastic effect. Following the non-direct procedure proposed, both the depth of each defect and its main dimensions have been retrieved into a satisfactory accuracy.

Moccasin, skin shoe worn by indigenous people of North America, excepting the sandal wearers of the Southwest area. There were two general types of moccasins, the hard-soled, which was used in the Eastern woodlands and the Southeast cultural areas, and the soft-soled, used in the Plains area. The hard-soled moccasin was made by sewing, with sinew thread, a rawhide sole to a leather upper piece; the soft-soled moccasin was one piece of soft leather with a seam at the instep and the heel. Boot or legging moccasins (sometimes reaching the hip) were worn from Alaska to Arizona and New Mexico, but they were generally part of the woman's costume. The moccasins of certain tribes were distinctive, and sometimes a moccasin track could indicate the tribe of the wearer. Moccasins were usually symbolically decorated with porcupine quills and, after the coming of the Europeans, with glass beads. Special moccasins were used for ceremonies such as the Iroquois adoption service, which required that a recruit put on Iroquois moccasins to indicate that he would follow Iroquois ways.

概要 It has been revealed that the formation of the Japan Sea Proper Water (JSPW) in both intermediate and deep layers has been stagnating since the 1960s, accompanying with a relatively active intermediat...e water formation. This study demonstrates such a situation using a simple vertical advection-diffusion box model. The box model qualitatively reproduced the interdecadal oscillation superimposed on the decreasing trend in the dissolved oxygen (DO) concentration throughout the JSPW. However, the simulated amplitude of the interdecadal oscillation in the DO concentration in the deep layers is very small compared with the observed one. This implies that the vertical diffusion is not the main cause of the interdecadal oscillation in DO in the deep layer.続きを見る

Buccinator muscle
Last revised by Henry Knipe on 31 Dec 2021
The buccinator muscle is one of the facial muscles located in the cheek, between the maxilla and mandible, and functions chiefly as a muscle of mastication.
 - origin: outer surface of alveolar processes of both maxilla and mandible, and anterior margin of the pterygomandibular raphe 1
 - insertion: converges on the modiolus of the mouth, where some fibers decussate to interdigitate with the contralateral muscle
 - arterial supply: branches from the facial artery, buccal branch from the maxillary artery 1
 - innervation: buccal branch of the facial nerve
 - action: directs a food bolus onto the teeth, tenses the cheek and helps to close the mouth
The anterior border of the pterygomandibular raphe gives origin to the fibers that decussate at the modiolus of the mouth. Fibers arising from the maxilla and mandible, do not decussate and insert into the upper and lower lips respectively.
The buccinator muscle is pierced by the parotid duct on its lateral aspect, opposite the upper third molar tooth 1.
The buccinator muscle is categorically a muscle of facial expression as it is derived from the 2nd pharyngeal arch, and thus innervated by the facial nerve. Despite this, its primary function is assisting with mastication 2.

In order to evaluate the mechanical properties of a very thin film, this paper proposes a convenient method for separately determining Young's moduli of two thin films of a magnetic recording medium. Furthermore, the particular stress distribution inside a magnetic recording film (two bonded thin films) is analyzed. The internal stress in the medium is not uniform when the medium is subjected to unidirectional tension. The analysis shows that the difference in Poisson's ratio on two thin films causes flexure of the two bonded films under tension, as well as shearing stress at the interface between the magnetic layer and the substrate. Since the shearing stress may cause fatigue damage of the tape edge, detailed FEM analysis on its distribution is carried out.

African Mask Plant
3.0 out of 5 (1 experiences)
What other plant parents say
Ali Asia Polly, my Diva, is finicky af. Currently in rescue mode...AGAIN 🙄...but such beautiful leaves when she's pleased. Must have right conditions. Mine will be going into a climate controlled IKE…
How to care for African Mask Plant
African Mask Plant needs 0.5 cups of water every 9 when it doesn't get direct sunlight and is potted in a 5" pot.
Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
African Mask Plant may have difficulty thriving, and will drop leaves 🍃, without ample sunlight.
Place it less than 3 feet from a south-facing window to maximize the potential for growth.
Select your city to see how the current weather in your area affects the placement of African Mask Plant in your home 🏡.
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it's likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your African Mask Plant after it doubles in size or once a year—whichever comes first.


703. Kth Largest Element in a Stream
703. Kth Largest Element in a Stream
An example of using std::priority_queue
Problem statement
Design a class to find the k-th largest element in a stream. Note that it is the k-th largest element in the sorted order, not the k-th distinct element.
Implement KthLargest class:
 - KthLargest(int k, int[] nums) Initializes the object with the integer k and the stream of integers nums.
 - int add(int val) Appends the integer val to the stream and returns the element representing the k-th largest element in the stream.
Example 1
Input
["KthLargest", "add", "add", "add", "add", "add"]
[[3, [4, 5, 8, 2]], [3], [5], [10], [9], [4]]
Output
[null, 4, 5, 5, 8, 8]
Explanation
KthLargest kthLargest = new KthLargest(3, [4, 5, 8, 2]);
kthLargest.add(3); // return 4
kthLargest.add(5); // return 5
kthLargest.add(10); // return 5
kthLargest.add(9); // return 8
kthLargest.add(4); // return 8
Constraints
 - 1 <= k <= 10^4.
 - 0 <= nums.length <= 10^4.
 - -10^4 <= nums[i] <= 10^4.
 - -10^4 <= val <= 10^4.
 - At most 10^4 calls will be made to add.
 - It is guaranteed that there will be at least k elements in the array when you search for the k-th element.
Solution 1: Sort and Append
Sort the stream when initialization. And keep it sorted whenever you append a new value.
Example 1
For nums = [4, 5, 8, 2] and k = 3.
 - Sort nums = [8, 5, 4, 2].
 - Adding 3 to nums. It becomes [8, 5, 4, 3, 2]. The third largest element is 4.
 - Adding 5 to nums. It becomes [8, 5, 5, 4, 3, 2]. The third largest element is 5.
 - Adding 10 to nums. It becomes [10, 8, 5, 5, 4, 3, 2]. The third largest element is 5.
 - So on and so on.
Code
#include <vector>
#include <algorithm>
#include <iostream>
using namespace std;
class KthLargest {
 vector<int> _nums;
 int _k;
public:
 KthLargest(int k, vector<int>& nums) : _nums(nums), _k(k) {
 sort(_nums.begin(), _nums.end(), std::greater());
 }
 int add(int val) {
 auto it = _nums.begin();
 while (it != _nums.end() && val < *it) {
 it++;
 }
 _nums.insert(it, val);
 return *(_nums.begin() + _k - 1);
 }
};
int main() {
 vector<int> nums{4,5,8,2};
 KthLargest a(3, nums);
 cout << a.add(3) << endl;
 cout << a.add(5) << endl;
 cout << a.add(10) << endl;
 cout << a.add(9) << endl;
 cout << a.add(4) << endl;
}
Output:
4
5
5
8
8
Complexity
 - Runtime: O(NlogN), where N = nums.length.
 - Extra space: O(1).
Solution 2: Priority queue
There is a data structure that has the property you want in this problem.
It is std::priority_queue, which keeps its top element is always the largest one according to the comparison you define for the queue.
By default, the "less than" comparison is used for std::priority_queue and the top one is always the biggest element.
If you want the top one is always the smallest element, you can use the comparison "greater than" for your queue.
Code
#include <vector>
#include <queue>
#include <iostream>
using namespace std;
class KthLargest {
 priority_queue<int, vector<int>, greater<int>> _q;
 int _k;
public:
 KthLargest(int k, vector<int>& nums) :
 _q(nums.begin(), nums.end()), _k(k) {
 }
 int add(int val) {
 _q.push(val);
 while (_q.size() > _k) {
 _q.pop();
 }
 return _q.top();
 }
};
int main() {
 vector<int> nums{4,5,8,2};
 KthLargest a(3, nums);
 cout << a.add(3) << endl;
 cout << a.add(5) << endl;
 cout << a.add(10) << endl;
 cout << a.add(9) << endl;
 cout << a.add(4) << endl;
}
Output:
4
5

Complexity
 - Runtime: O(N), where N = nums.length.
 - Extra space: O(1).

Sigesbeckia
For joint and muscle pain
About Sigesbeckia
Sigesbeckia, sometimes spelt Siegesbeckia (although the correct spelling is Sigesbeckia according to a paper published by The Royal Botanic Gardens, Kew in Proceedings of the Botanical Society of the British Isles in 1967), is an annual plant from the Asteraceae family. There are several species that make up the genus. In traditional medicine, the most commonly used species are Sigesbeckia orientalis, Sigesbeckia pubescens and Sigesbeckia glabrescens, although botanists at the Royal Botanic Gardens, Kew, do not recognised pubescens as a separate species, but rather as a subspecies of Sigesbeckia orientalis. The plant has a number of medicinal properties, principally relating to musculoskeletal disorders, but research also shows health benefits relating to immunity and hypertension.
Traditional Use
The first recorded use of Sigesbeckia was in China in 7th century AD, where the plant, under its Chinese name Xi Xian Cao, was recorded in the Tang Materia Medica in 659AD as a medicine for eliminating 'wind-damp'. Its use as a medicinal plant continued through the ages, and was referenced in the first of the modern Chinese Pharmacopeias in 1963, where its use to treat backache, joint pain, sciatica, rheumatic pain and muscular pains are described. It has also been widely used across Europe since at least the 1980s as a treatment for backache, joint and muscle pains, although it was referenced as a medicinal plant in Europe as far back as 1907 in Potter's Cycolpedia of Botanical Drugs and Preparations where it is referenced as a remedy for syphilis, venereal diseases and leprosy.
Medical Use
Sigesbeckia is used in modern traditional Chinese medicine to treat various forms of arthritis, rheumatic pain, back ache, sciatica. It is often used as part of a formula with other plants in decoctions. In 2015, the extract of the aerial parts of Sigesbeckia orientalis subsp pubescens was licensed by the UK Medicines and Healthcare Products Regulatory Agency (MHRA) as an over-the-counter medicine for backache, joint and muscle pain, and for minor sports injuries based on its longstanding use as a traditional medicine. In the USA, it is approved for use in dietary supplements for promoting healthy joints. It is also used in cosmetics and personal care products due to its anti-inflammatory activity.
Modern Research
Modern scientific research has shown that the molecules in Sigesbeckia have a number of pharmacological actions. It has been shown to be an anti-inflammatory and analgesic, supporting its use in musculoskeletal diseases. It has been shown to modulate cellular immunity, humoral immunity and nonspecific immunity, as well as adjusting cytokine production in the bodies immune function which could be beneficial for auto-immune arthritic conditions, such as rheumatoid arthritis.

- Learn what inspired the White House Kitchen Garden and follow its progress from planting to harvest
- See how gardens can help build stronger communities and encourage healthy lifestyles
- A fact-filled and thought-provoking book with colorful photographs that bring the story to life
In American Grown, First Lady Michelle Obama tells the story of what inspired her to plant the White House Kitchen Garden in the spring of 2009, and then documents the garden's progress though the growing season, from designing and planting to tending and harvesting. The author
candidly shares her challenges as a novice gardener, as well as her joy at watching lettuce, tomatoes, collards, sweet potatoes and other crops flourish
on the South Lawn.
As the White House Kitchen Garden grew, so did the national conversation about the way we eat and the impact it has on the health and well-being of
our children. Throughout the book, the author weaves in stories about gardens all across the country, from a WWII-era Victory Garden in Chicago to
urban and school gardens that not only provide nutritious harvests for the gardeners, but also build community, stock food shelves and teach children
important lessons about making healthy life choices. The book also includes loads of helpful tips for home gardeners, plus recipes for making the most
of the harvest.
