Right now I am reading a proof of Downward Löwenheim-Skolem theorem in Hodges, but I am slightly confused about a proof Hodges makes. Let me write down some of the definitions.
Definition: Let $T$ be a first-order theory in a first-order language $\scr{L}$. >Then a skolemisation of $T$ is a theory $T^+\supseteq T$ in a first order >language $\scr{L}^+\supseteq \scr{L}$ such that
 1. Any model of $T$ can be expanded to a model of $T^+$.
 2. For every formula $\phi(\bar{x}, y)$ of $\scr{L}^+$ with $\bar{x}$ a nonempty tuple, there is a term $t$ of $\scr{L}^+$ such that $$ T^+\vdash \forall \bar{x}(\exists y\phi(\bar{x}, y)\to \phi(\bar{x}, t(\bar{x}))). $$
A theory $T$ is said to be a Skolem Theory or to have Skolem functions if $T^+:=T$ and $\scr{L}^+ = \scr{L}$ is a skolemisation of $T$, i.e. $T$ is a skolemisation of itself.
Hodges goes on to say that for a Skolem theory $T$, and $A$ a model of $T$ and $X$ a subset of $A$, if the skolem hull $B:=\langle X\rangle_A$ is nonempty, then it is an elementary substructure of $A$. He proves this by invoking the Tarski-Vaught Criterion for elementary substructures. In particular, if $\phi(\bar{x}, y)$ is a $\scr{L}$-formula and $\bar{a}$ is a tuple from $B$ with $A\models \exists y \phi(\bar{a}, y)$, then $A\models \phi(\bar{a}, t(\bar{a}))$ for the appropriate term $t$. But $t^A(\bar{a})\in B$ as $B$ is closed under the functions, and he concludes that $B$ satisfies the Tarski-Vaught Criterion and so $B\preceq A$.
Here is my question, what if $\phi(\bar{x}, y)$ is actually $\phi(y)$? Then $\exists y\phi(y)$ is a sentence and so does not have a Skolem function. So if $A\models \exists y\phi$, how can we guarantee that $B$ possesses a witness to $\exists y\phi$?
My attempt to work around this is to consider the formula $$ \psi(x, y): = \ulcorner \phi(y)\wedge x=x\urcorner. $$ Then $\exists y\phi(y)$ is logically equivalent to $\exists y \psi(x, y)$. As $T$ is a skolem theory, there is a term $t(x)$ such that $$ T\vdash \forall x(\exists y\psi(x, y)\to \psi(x, t(x))). $$ Then for any $a\in B$, $t^A(a)$ will be an element of $B$ witnessing $A\models \exists y\phi$. Is this a correct resolution of my question, or is there something else I am missing? Thanks for the help!

Yes, your solution works. A less "cheap" way to resolve things is to remove the word "nonempty" from Hodges' definition, so that $(\exists y)\phi(y)$ has a zero-ary Skolem function, that is, a "Skolem constant" $c_\phi$. That is the definition of a Skolemization some others use. (I am not familiar with Hodges' definitions and conventions; he might not require that a variable shown in a formula name must actually appear, in which case he could write "$(\exists y)[y = y]$" as $\phi(x)$.)

Using detailed computer simulations, Oxford University research has revealed why falcons dive at their prey using the same steering laws as man-made missiles.
Published today in PLOS Computational Biology, researchers from Oxford's Department of Zoology use computer simulations of peregrine falcon attacks to show that the extreme speeds reached during dives from high altitudes enhance the raptors' ability to execute manoeuvres needed to successfully attack agile prey that would otherwise escape.
Professor Graham Taylor and PhD student Robin Mills, alongside colleagues from the University of Groningen, built a physics-based computer simulation of bird flight that pits falcons against prey. The team had previously shown that falcons attack their prey using the same steering rules as man-made missiles.
The simulation incorporated the aerodynamics of bird flight, how birds flap and tuck their wings, how falcons perceive their prey and react to it with delay and how falcons target their prey like a missile. It showed that high-speed dives enable peregrines to manoeuvre faster, producing much higher aerodynamic forces, thereby maximising their chance of seizing agile prey.
In addition the simulation showed that high-speed dives require very precisely tuned steering for a falcon to attack successfully, revealing that the stoop is a highly specialist hunting technique. The research team found that optimal tuning of the mathematical laws that control steering in the simulation corresponded closely to measurements of steering for real falcons.
The team is now extending its simulation to explore other unique and specialised attack strategies as well as escape tactics employed by different raptor species.
'Ultimately,' says Mills, 'we aim to understand the arms race between aerial predators and their prey that has led raptors to become some of the fastest and most agile animals on Earth.'

Overview Of Curved Glass
Measuring for a curve
Measuring for a curve, like everything else, is simple when you know how.
We hope the following guidelines will be of some help.
The main principle to understand is that accuracy is achieved by working/ measuring from point to point.
For example in the sketch below, the blue line and dots represent external point to point dimensions of a panel of glass. i.e chord, radius, depth of bend, and girth. The red line and dots represent the internal dimensions of the same panel of glass.
For us to produce curves from measurements supplied we need accurate details of at least 1 of the following options, along with the height.
 - 1. Radius and angle of arc (specify whether int. or ext)
 - 2. Radius and chord
 - 3. Chord and depth of bend
The above holds true once the curve represents a part or segment of a circle. However where the curve is an irregular shape, either elliptical or part curved with part straight, then we would always recommend taking an accurate template of the shape. Of course where templates are being provided, like with measurements it is important to specify what they represent: int. or ext or centre.

The nature of urban economic design in Kumasi, Ghana, is often reflective of neoliberal economic policies prescribed by Bretton Woods institutions during the economic reforms of the 1980s. The economic structure, which is characterized by uncertainties of formal jobs, has triggered people's ingenuity to engage in novel occupations. One economic activity that has gained popularity in Kumasi is vending of roasted traditional food (RTF) by women. This chapter explores how women have used vending of RTF to overcome years of acute austerity in the "paid" job market. It concentrates on the economic, spatial, and social networks that sustain this informal activity. Drawing on multiple data sources, the results confirm how the structure of the city space has consigned RTF vendors to obscurity, yet their activities are responding to the economic realities of time—increasing urbanization, limited job opportunities, and accumulation of poverty. As a survival strategy, the vendors have developed social connections with clients and made their place comfortable in order to claim their rightful place in the urban space economy. We conclude that given their contributions, the vendors must be appreciated as agents of change and part of the urban system.

This paper assesses local biodiversity monitoring methods practiced in the Tonle Sap Lake of Cambodia. For the assessment we used the following criteria: methodological rigor, perceived cost, ease of use (user friendliness), compatibility with existing activities, and effectiveness of intervention. Constraints and opportunities for execution of the methods were also considered. Information was collected by use of: (1) key informant interview, (2) focus group discussion, and (3) researcher's observation. The monitoring methods for fish, birds, reptiles, mammals and vegetation practiced in the research area have their unique characteristics of generating data on biodiversity and biological resources. Most of the methods, however, serve the purpose of monitoring biological resources rather than biodiversity. There is potential that the information gained through local monitoring methods can provide input for long-term management and strategic planning. In order to realize this potential, the local monitoring methods should be better integrated with each other, adjusted to existing norms and regulations, and institutionalized within community-based organization structures.

Dragon Breed Data
Origin Of Name?
There are several Australian butterflies with "Xenica" in their common names from the parent genera Geitoneura, Oreixenica, and Nesoxenica. The first named variety was the Ringed Xenica in 1805, with marbled orange/black wings marked with white-centered black eyespots.
In Temeraire's world, perhaps the Australian butterfly was named for a similar appearance to the British dragon. Conversely, perhaps Novik named the dragon after the butterfly.

LEVELS OF GOVERNMENT
In Australia, each jurisdiction has its own laws and policies for responding to FDV, whilst the Australian Government takes a lead in developing national approaches to policy. More information on the policy context for FDV can be found in the Conceptual Framework for Family and Domestic Violence, Australia, 2009 (cat. no. 4529.0).
Most Australian Government FDV service delivery occurs through funding arrangements with states and territories, however reporting obligations mean that there are also a number of Australian Government level data sources. National data sources have been included where available from Australian Government agencies, such as those relating to FDV services provided in the Family Court context and the drawing together of state and territory information related to homelessness services and coronial inquests. In addition, national data sources based on surveys run by or on behalf of the Australian Government to inform FDV policy areas have been included.
At the state and territory level, governments are primarily responsible for crime prevention programs, law enforcement, issuing of family violence orders, prosecution of FDV perpetrators, behavioural change programs within Corrective Services, delivery of public health, disability and medical services and provision of child protection services and other specific FDV services. Each state and territory agency that provides FDV services is a potential source of data. Further information about FDV support and services delivered by each jurisdiction, including the Australian Government is outlined in the National Plan to Reduce Violence against Women and their Children.

Exclusive Optionals
When you are developing a module that provides several ways of configuring the same thing, but only one of them should be used, you might need to set the following rule:
 - From a given set of parameters, only one shall be used at any time.
You use @ExclusiveOptionals to enforce this restriction.
@ExclusiveOptionals
The @ExclusiveOptionals annotation can only be used on types that are used as a @ParameterGroup (see Parameters for details).
Example
@ExclusiveOptionals
public class ExclusiveOptionalsExample {
 @Parameter
 private String requiredParameter;
 @Parameter
 @Optional
 private String optionalParameter;
 @Parameter
 @Optional
 private String anotherOptionalParameter;
}
As the name of the annotation implies, the exclusivity restriction only applies to the optional parameters. So, setting requiredParameter at the same time as optionalParameter or anotherOptionalParameter is allowed, but setting optionalParameter and anotherOptionalParameter at the same time causes an error to be thrown.
Tip: You can have as many parameters as you want inside an object that is annotated with @ExclusiveOptionals, but only one optional parameter is allowed to be set at any time.
Enforcing At Least One Parameter
There can be cases where exactly one (but no more than one) of the optional parameters must be set. You can configure this requirement by using @ExclusiveOptionals(isOneRequired = true), for example:
@ExclusiveOptionals(isOneRequired = true)
public class OneRequiredExample {
 @Parameter
 private String requiredParameter;
 @Parameter
 @Optional
 private String optionalParameter;
 @Parameter
 @Optional
 private String anotherOptionalParameter;
}
So, an error is thrown if you set requiredParameter but do not set one of the optional parameters: optionalParameter or anotherOptionalParameter.

Grundfos CU301 Controller for Communication with SQE Pumps
CU 301 are designed for communication, monitoring and control of SQE submersible pumps in constant pressure applications.
The Grundfos CU 301 is a control and communication unit developed for the SQE submersible pumps for applications where a constant pressure is required.
The CU 301 provide full control of the SQE pumps and enables the system to maintain a constant pressure within the maximum pump performance in spite of a varying water consumption. The pressure is registered by the pressure sensor and transmitted to the CU 301. The CU 301 adjusts the pump performance accordingly.
The CU 301 control unit provides the following:
- Two-way communication with the SQE pumps.
- Possibility of adjusting the pressure.
- Alarm indication of pump operation by diodes on the front.
- Possibility of starting, stopping and resetting the pump simply by means of a push-button.
The CU 301 communicates with the pump via mains-borne signaling (Power Line Communication), meaning that no extra cables are required between the CU 301 and the pump.
The CU 301 indicates the following alarms:
- No contact,
- Dry running,
- Speed reduction,
- Sensor alarm.
The CU 301 incorporates the external signal input for pressure sensor and connection to an operating relay for enabling aeration or chlorination during pump operation. As well a safety relay to disconnect the SQE submersible pump during communicating failure, it will then operate in pressure switch mode if the pump is still running and until communication to the pump has been restored.


harsh conditions. Here are five things to know about child poverty in Lebanon.
5 Facts About Child Poverty in Lebanon
 1. Poverty by the Numbers: There is severe inequality in Lebanon as 5-10% of the population receives more than half of the total national income. Around 25-30% of Lebanese people live in poverty. Refugees and other populations face an even higher rate of poverty. For all of these groups, families with children are more likely to live in poverty. Current estimates say 1.4 million children in Lebanon are living in poverty. This affects their ability to receive an education, adequate nutrition and water and future standard of living and employment.
 2. Education: An estimated 10% of children in Lebanon do not attend school. The schools that do exist are low quality in both education and the physical state of the buildings. The poor education in Lebanon causes less young people to acquire jobs in technical or competitive fields. Armed and violent conflicts in Lebanon have also damaged school buildings. Furthermore, children's access to education is hindered by the 1925 Nationality Law, in which only children with Lebanese fathers receive citizenship. If a child's only parent is their mother or the father is not Lebanese, public schools will not admit them until all other Lebanese children are enrolled.
 3. Child Labor: Lebanon has lower rates of child labor than many of the surrounding countries, but still 7% of children work. Many of these children work to support their families, though their salaries are often low. Boys often work in factories or agriculture which have inhumane and very harsh working conditions. Lebanon has signed on to the ILO's Convention on Child Labor, but this has not decreased child labor.
 4. Refugee Children: Lebanon has a very high number of refugees living inside its borders because of its geographical location. These refugees come from Iraq, Syrian, Palestine and more. The majority of refugees live in extreme poverty. Refugee children often work in poor conditions to make money. Many also suffer from mental health problems due to their trauma. In refugee camps, children face many dangers, including domestic violence, drug use and minimal health care and basic hygiene. Lebanon has not ratified the U.N. Convention Relating to the Status of Refugees, and does little to protect these people living inside the country. The country also lacks the resources to address children's mental health problems, but NGOs are working to provide more medical help inside the refugee camps.
 5. Reducing Child Poverty: The Government of Lebanon launched the National Poverty Targeting Program in 2011. The World Bank provided technical and financial assistance to this program to provide a safety net for families living in extreme poverty. Families are chosen based on level of food security, labor force status and other variables. This program currently helps 43,000 households, although more than 150,000 families are in extreme poverty and more than 350,000 qualify are in poverty. The families benefiting from the program receive a "Hayat Card," which gives them access to free health care and educational services, and the poorest receive a debit card for food.
Children in Lebanon are still heavily affected by poverty, whether it is through health care, education or labor. Refugee children and girls are particularly vulnerable as they lack basic rights under law. Although strides have been made in recent years to eradicate poverty, the government and other organizations must prioritize addressing child poverty in Lebanon.

3RF: Helping Lebanon Recover from the Beirut Explosion
The United Nations has announced a new plan to support Lebanon after Beirut's deadly explosion in August 2020. Operating in conjunction with the World Bank and the European Union, the U.N. has named its program 3RF, short for "Reform, Recovery[ ] and Reconstruction Framework." Lebanon has long struggled under the weight of political and economic crises, which the explosion in its capital city only exacerbated. Therefore, 3RF comes as an effort from the international community to improve conditions in Lebanon over the long term.
An Explosion in the Capital
Shortly after 6 p.m. local time on August 4, 2020, a colossal explosion at Beirut's port sent shockwaves rippling through the city. The disaster killed 200 people, injured thousands more and rendered approximately 300,000 individuals—out of the city's total population of 2 million—homeless and destitute.
Officials have since identified the cause of the explosion as 2,750 tons of improperly stored ammonium nitrate, a chemical found in fertilizer. A welding project in one of the port's warehouses sparked a fire that triggered the blast.
Shockwaves blew out windows at Beirut International Airport five miles away, and scientists from the United States Geological Survey reported that these equated to a 3.3-magnitude earthquake. Besides destroying commercial buildings and residential properties, the explosion also incapacitated three major hospitals and more than 24 clinics. Victims flooded the remaining healthcare centers, placing further strain on a system already contending with the COVID-19 pandemic.
Economic Crisis
Unfortunately, Lebanon was beset by problems before the August 2020 explosion. Public discontent has simmered for years, stoked by political corruption, economic hardship and a government struggling to provide services like reliable power and clean drinking water.
In October 2019, following a foreign currency shortage and the eruption of major wildfires, the Lebanese government announced new taxes in a bid to raise desperately needed revenue. However, the Lebanese government scrapped the plans after large-scale protests gripped the country.
Then, after lockdown measures underwent implementation in March 2020 to slow the spread of COVID-19, Lebanon's economic crisis worsened. As businesses had to fire employees or place them on furlough without pay, prices on basic goods rose to prohibitory levels. In May 2020, former Prime Minister Hassan Diab wrote in The Washington Post that much of the country's population had ceased buying meat and fresh produce and that soon people would be unable to afford bread.
Poverty and Corruption
The blast in Beirut has significantly compounded the hardships that Lebanese people have faced. Many residents within the financial capital have experienced trauma, including older citizens for whom the explosion brought up memories of the violent Lebanese Civil War (_PHONE_). Additionally, more than 55% of the country lives below the poverty line, almost doubling the percentage registered in 2019. Extreme poverty has also surged within the past year, rising from 8% to 23%.
Unfortunately, corruption among Lebanese political elites has meant the lack of a government-led recovery plan. Popular protests in the wake of revelations about mismanagement of the ammonium nitrate at Beirut's port led to the mass resignation of then Prime Minister Hassan Diab's government. Instead, volunteers and NGOs have spearheaded efforts to clean up the city. Funds raised abroad have gone straight to these NGOs on the ground, bypassing the Lebanese government due to the international community's lack of trust in its leaders.
3RF and Lebanon's future
The program 3RF aims to address the desperate situation in Lebanon. Announced at the recent International Conference in Support of the Lebanese People, the plan underscores urgent needs for political reform to solve the root causes of Lebanon's economic crisis. Such reforms will facilitate recovery and reconstruction in the long run.
For his part, U.N. Secretary-General António Guterres called upon political leaders in Lebanon "to put aside partisan political interests and form a government that adequately protects and responds to the needs of the people." The International Monetary Fund also promised to help but emphasized the importance of active participation from a legitimate Lebanese government during the reform process.
Conditions for Lebanon's people have been difficult during 2020. Stemming from a spiraling economy and political corruption, the COVID-19 pandemic and the catastrophic explosion at Beirut's port exacerbated these hardships. With thousands of people homeless and poverty rising, the U.N.'s 3RF will hopefully provide immediate relief while also laying the foundation for better governance in the future. Pressure from the international community can likewise encourage Lebanese leaders to form a new government and begin implementing necessary reforms.

Research Impact : The cautious climate in Ireland of teachers being involved in assessing students' work is delaying the enactment of such curricula and, more specifically for this paper, currently hindering associated assessment processes. It is therefore fitting and timely to explore the extent to which the current discussions in Ireland around teachers being responsible for assessing their own students' work is subsequently impacting (or not) the delivery and assessment of physical education. This discussion is particularly timely given the very recent endorsement of the introduction of the new Leaving Certificate Physical Education as a full optional subject.

Names of African Slaves in Puerto Rico/
Puerto Ricans are West Indians also, for Puerto Rico is part of the West Indies once owed by Visoguth colonizers, they took the land from the original people name Taino who they subjugated and made the taino slaves, Some Taino survived and are still in Puerto Rico and many Puerto Ricans are mixed with Taino and mixed with the blood of the African whether they are black skinned or white skin. Puerto Rico is the Spanish West Indies, but in reality it is the land of the Taino. The African was taken to Puerto Rica as slaves.
Stripped of their identity and African Homeland and taken to Puerto Rico, these are the slaves, that brought the soul, the sounds of the drums, the dance, the knowledge, the science of healing, the religion of yaruba, islam, african christianity,and brought the beauty of the falani, mandingo, and hundreds of other beutiful african tribes to puerto rico. Gone But not Forgotten, their ancient advance civilizations lives on in puerto rico history, black and beutiful, your souls live on. here are some of their names: From: Ponce,San Anton, Puerto Rico Esclavos(slaves) born in Africa.

Insert Line Breaks
Normally, the text entered as first parameter of MessageBox is displayed as a continuous line that the engine breaks where it sees fit according to line's total length and length of separate words. With a bit of hex editing, though, you can make it look more formatted.
Let's say, you want a MessageBox to report the amount of certain enemies you killed like this:
Score: Daedra Lords: 21 Golden Saints:37 Fargoths: 9999
If you try to make a MessageBox with line breaks in the CS, it will take it as several lines with different operators and refuse to compile it. You'll have to deceive the CS. First, you write an operator:
MessageBox "Score:|Daedra Lords: %.0f|Golden Saints:%.0f|Fargoths: %.0f", k_Dae, k_Snt, k_Far
Compile the script and save your mod. Now you'll need a hex editor like WinHex (or any that you prefer). Open your.esp with it and find the message text. It will be found there twice - first time in the body of a compiled script, second in the source text. You'll need the first one. Replace all symbols '|' with the hexadecimal code 0A (line feed) and save the file. Now, when you play the mod, the engine will recognize line breaks properly and display your MessageBox as you wanted it.
Just keep in mind that if you change and recompile the script, imposed linebreaks will be lost and you'll have to repeat the operation again.

Shepherds Passing

Prometheus and Atlas
Prometheus and Atlas
Without as much as a wave shepherd moons Prometheus and Atlas pass by each other, each on their own paths around the rings.
Prometheus, casting a long shadow, pulls at the F ring's bands of material while smaller Atlas guards the edges of the A ring. The larger is 93 miles across at its widest point, the other is 23 miles wide. Both moons are irregularly-shaped, Prometheus extremely so.
The vertical banding visible in this modified raw image is a result of Cassini's imager, not a feature of the rings. See the original image here.

Viper uses G-Force.
|Description||Utilize gravity's pull to swing sword harder.|
Viper charges at the target and slices them with his weapon. He then hops into the air, swings his sword, and crashes down on the target's head. The resulting blow cascades in a fountain of yellow and white sparks.
G Force is a scientific term used to describe the rate at which an object accelerates as it falls. In this tech, Viper exploits this gravitational momentum to unleash more powerful blows.

Cleaning your patio-DIY or Call in a Pro?
With so many of us spending more time at home these days, getting the patio in tip-top shape has become a priority.
While pavers are known for being easy to care for, occasional maintenance is needed to keep them looking their best. Some patios may just need a quick once-over with detergent and soft-bristle brush, while others require a visit from a pro to restore them to their original beauty.
Prepare the space and Evaluate your needs
You should begin by clearing the space. Furniture, plants and decorative items will need to be removed to properly clean the space.
- Look for leaf stains, grease from food and mildew. Determining what kind of stains you have will determine what you'll need to do to fully restore them.
- Check the joints. The sand used between the joints can wear away over time.
- Weeds. Missing sand or overgrown plant beds can allow weeds to creep onto your patio.
- Sweep or blow off any loose debris.
- Hose down pavers with clear water.
- Most food grease or oil stains can be removed using a de-greasing dish soap (like Dawn) directly onto the stain.
- Use a paper towel to soak up any surface grease.
- Drizzle scaling hot water from a tea kettle and thoroughly rinse it off the surface.
- Apply Dawn dish detergent full strength onto the stain and allow it to sit on the for 20-30 minutes.
- Scrub with a standard household nylon bristle scrub brush.
- Rinse with hot water.
- Repeat as needed to remove as much of the stain as possible.
- Mildew can be removed by using a bleach solution. 10 parts water to 1 part bleach.Mix the solution in a watering can with a sprinkle spout.
- Apply the bleach solution over the entire surface saturating the area and leaving a liquid film on the Hardscape™ surface.
- Allow the bleach solution to remain on the surface for 20 – 30 minutes. The moss, mildew, or algae should turn brown, which indicates it has been killed.
- After letting the bleach solution sit on the surface, scrub the surface with a stiff nylon bristle brush and rinse thoroughly with fresh water. Repeat if needed.
- Do not make your bleach solution stronger, as it may affect the color of your Hardscaping.
- Be careful not to get the bleach solution directly on grass or plant material. If there are plants or grass where you expect to rinse the residue on to, saturate that area with water first.
Keep in mind that if the area is in a damp or shady location it will keep growing back. For a more permanent solution, you will need to correct the moisture and shade problems that are encouraging the moss, mildew, or algae to growth.
For tougher stains, such as motor oil or grease, visit Techni-Seal. Here, you'll find information and instructions for their paver cleaning products that are sold at your local EP Henry Authorized Hardscaping Distributor
And remember, one of the major advantages of paving stones is, if they are damaged or stained beyond repair, they can always be removed and replaced at a minimal expense.
- Sweep or blow odd any loose debris
- Get a weed killer, such as Weed-B-Gone
- Use as directed.
- After the weeds have been killed, carefully remove them from the sand joint. Take as much of root out as possible without disrupting or removing the sand joint.
Most installations have polymeric sand. This sand is formulated to harden over time, so it holds together and does not blow or wash out of the sand joints. This allows it to remain in place and resist weed growth.
- Before replacing sand, any existing sand must be removed.
- Enough of the preexisting polymeric sand must be removed from the sand joints (1.5" or more) to allow enough new polymeric sand into the sand joint so it can achieve structural stability when it is moistened.
- If possible, use the same polymeric sand that was originally used so that it bonds properly.
Note: You may want to leave this for the pros, because if done incorrectly, it could leave your pavers with an unsightly haze.
This is another project best left for a professional. Sealing requires an experienced hand in order to avoid pooling and missed spots. Done incorrectly, sealing can be expensive to correct.
In conclusion, while easier cleaning projects can be a do-it-yourself (or family) project, projects that require experience or trade skills are better left to hardscaping specialists. Done right, you'll be enjoying your patio or pool in no time.

Allotment Garden in Kupittaa
The Kupittaa allotment garden is the oldest in Turku - founded in 1934. It is a green oasis and a socially vibrant and active part of the city of Turku. Visitors are welcome to explore and enjoy the area through out the year.
The allotment garden has retained its character over 85 years and is a very significant urban environment as a whole, enriching biodiversity in the Kupittaa area. The area includes 57 plots with very small cottages. Three of the cottages are in their original appearance, as the others show a spectrum of variations that has developed over the decades, with minor changes. Originally the allotment garden was established to ensure the food supply of the families as well as to offer recreation and promote the well-being of the city's working population. Although the primary function of the plots is no longer to feed the gardeners, there are still about 300 apple trees in the area, some of them decades old. In addition to them, the plots grow a large number of old ornamental and useful plants.
In Kupittaa, all cultivation is carried out without pesticides and the Kupittaa allotment garden, with its vegetation and other organisms, is a "hotspot" of the city's biodiversity. The University of Turku and the Natural Resources Institute Finland have documented the valuable vegetation of the garden and some of them have been deposited in the Natural Resources Institute's crop genetic resources collections. The Federation of Finnish Allotment Gardens has listed Kupittaa as one of five allotment gardens worth a visit in Finland.
The Kupittaa allotment garden is maintain and developed by society called Kupittaa ryhmäpuutarhayhdistys. If you want to support the work of this society or you are interested in buying a cottage in the allotment garden, please contact _EMAIL_.
As part of urban planning, the city of Turku is considering to transform the Kupittaa allotment garden to housing area. Realising these plans would mean the end of the Kupittaa allotment garden and loss of its biodiversity. If you wish to help to preserve this unique pearl in the heart of Turku you can sign a petition for it.

Date of wing molt initiation, based on the regression of tenth primary length on capture date, was calculated for breeding and nonbreeding Tundra Swans (Cygnus columbianus columbianus) on the Colville River Delta, Alaska. Breeding females initiated wing molt significantly later than breeding males and nonbreeding males and females; the molt of breeding females was correlated with the date on which their eggs hatched. Breeding males did not differ significantly from nonbreeding males and females in the date of molt initiation. Timing of molt in breeding males and females was consistent with the views that females delay molt while replenishing energy spent on reproduction, but was also consistent with the breeding pair's need for primaries to defend territories and to defend and brood young. Other results, including an increase in an index of female body condition throughout most of the molt period, and a positive correlation between clutch size and female hatch-to-molt interval, were not predicted by the hypothesis that past energy expenditures constrain the timing of molt. Patterns of wing molt within and among other Northern Hemisphere geese and swans are also difficult to explain on the basis of energetics alone. For example, breeding females initiate molt before breeding males in many species. Also, there is extreme asynchrony between mates in two swan species; one of those species also exhibits variation in which sex initiates wing molt first. Both patterns suggest that asynchrony, per se, is important, probably to facilitate brood protection or territory defense. In Tundra Swans and other northern breeding geese and swans, the non-energetic demands of territory defense, brood defense, and brooding are probably important constraints on the timing of wing molt.

Riverside Park, Dawson Springs
Dawson Springs' Riverside Park, sometimes called Tradewater Park, was originally built in 1914 to serve as a spring training park for the Pittsburgh Pirates from 1914 to 1917. This is the only known baseball park in Kentucky to have hosted a major league team since the Louisville Colonels folded in 1899. While the original stadium was destroyed in a flood in the 1930s, it was later rebuilt in 1999. The park was reconstructed out of wood, just like the original stadium. It is the only ballpark of its kind in Western Kentucky. Riverside Park is now home to the Tradewater Pirates.

Dawson Springs is home to a mineral spring that was believed by many to have medical healing qualities. This led to Dawson Springs becoming a huge resort town. Thousands of people came to drink and bathe in the spring. Forty hotels sprung up to accommodate the health seekers. The large crowds that came to Dawson Springs was one of the reasons for the Pittsburgh Pirates to make it their spring training home.
Riverside Park was built in 1914 and served as the Spring Training Home of the Pirates from 1914 until 1917, when they moved to Hot Springs, Arkansas. The entire ballpark was made entirely from wood, from the grandstand to the dugout. Local citizens then constructed a large indoor pavilion for spring training and exhibition games and an additional wing was built onto the New Century Hotel to accommodate the players.
Some records from the era show that the Boston Red Sox and Cincinnati Reds also played expedition games there until the early 1920s. Teams came from all around to test the Pirates. They consisted of other major league squads, American Association teams, colleges, semi-pro teams, and even teams formed by local mining companies and businesses. Some teams came all the way from St. Louis, Chicago, Kansas City, Louisville, Indianapolis, Cincinnati and Philadelphia, as well as minor league squads from Columbus, Ohio and Toledo, Ohio to play at Riverside Park. However, once professional baseball left Dawson Springs, Riverside Park, while still hosting many local teams, among them members of the Kentucky-Illinois-Tennessee League (the Kitty League), continued to provide baseball for western Kentucky.
Sometime in the 1930s a devastating storm flooded a river that runs alongside the field's first base line, and washed away the entire stadium in a violent flood. In the decades following the flood, residents in Dawson Springs were only left with the memories of the ballpark.
Rebuilding the park
In 1999 Tradewater Park was rebuilt, as Riverside Park using the exact blueprints from 1914. Dawson Springs' Mayor Stacia Peyton funded a public project to rebuild the park. Public opinion reflected the need for the city to fund other civic needs instead of rebuilding an old ballpark. However Peyton pressed ahead with the plan, knowing how important the park was to the history of the city. The goal of the project was to make the stadium as authentic as possible to the original. Still, many locals believed the venture to be well-intended, but ill-fated. The largest stumbling block for the engineers reconstructing the park was in using only wood. The seats, roof, and beams were all made from wood, just like in 1914, to create a one-of-a kind ballpark. It is the only completely wooden ballpark in the region.
The Tradewater Pirates
The stadium was used until 2012 by the Tradewater Pirates of the KIT League and then the Ohio Valley League. The team was founded in 1999 and joined the KIT League in 2007. The Pirates' first game at Riverside was on July 4, 1999.
In 2008, the team celebrated its 10th anniversary. They are currently one of the most respected summer collegiate baseball programs in the nation.
Riverside Park also features the Hardball Cafe, featuring a menu of ballpark foods, flame-grilled meats, and a taco salad. The park is open daily from 9:00 a.m. to sunset, whenever no events are scheduled.
Honus Wagner and his buddies often went fishing at the Old Mill Dam, located right beside Riverside Park and a short walking distance from the New Century Hotel.

Original Language Japanese
In the cherry blossom's shade
there's no such thing
as a stranger.
|-- from The Enlightened Heart: An Anthology of Sacred Poetry, by Stephen Mitchell|
In Japanese Zen poetry, spring blossoms, particularly cherry blossoms, are often used as symbols for the simple, natural, unfolding springtime of enlightenment.
Understanding this, the rest of the poem opens up.
In the "shade" or, you might say, beneath the canopy of enlightenment, there is no longer any sense of separation. Nothing and no one is foreign to you. There is no such thing as a stranger.

JEFFERSON CITY, MO, NOV. 16, 2021 - The Missouri Department of Natural Resources is extending the deadline for Missouri communities to submit information on their water infrastructure funding needs.
Drinking water, wastewater and stormwater infrastructure projects in Missouri are critical to providing essential service to Missouri citizens and businesses, but are largely underfunded.
The American Rescue Plan Act (ARPA) provides funds that may be used to make necessary investments in water and sewer infrastructure to state, local and tribal governments. However, most communities have water funding needs that far exceed the amount of ARPA grant funds they were directly allocated.
Governor Mike Parson has announced a commitment to offer grants from the state's ARPA allocation for water infrastructure improvements. He will present his plan to the General Assembly at his State of the State address in January 2022.
To better understand the scope of Missouri infrastructure needs associated with wastewater, drinking water and stormwater utilities, the department is asking Missouri communities to complete a brief survey. The information gleaned from survey responses will help identify water infrastructure funding needs across the state and be used to develop state grant programs to help meet those needs.
The survey is intended to identify prospective projects that could be funded if grant funds were made available. The department is particularly interested in water infrastructure projects for which an engineering report has already been prepared, as well as projects that are difficult to finance with existing resources. Communities are encouraged to complete the survey with details about their projects, including estimated costs, available local cost share funding and the community's demographic information.
Grant programs will favor applicants who propose projects that are necessary for compliance and public health protection, demonstrate financial need and that provide local cost share funds to complete the work. Communities should consider retaining their local ARPA allocations to offer as cost share funds for state ARPA grant programs, likely increasing the community's chances of being awarded state ARPA grant funding.
To submit water infrastructure projects, visit _URL_. Surveys may now be submitted until 5 p.m. Nov. 30, 2021.
For more information, please contact the Water Protection Program's Financial Assistance Center at _EMAIL_ or _PHONE_.
To learn more about using ARPA funds for water infrastructure, visit State of Missouri's Local Fiscal Recovery Fund Toolkit for Water, Wastewater and Stormwater at oa2.mo.gov/ARPAtoolkits/water-infrastructure.

MTU size of VXLAN Tunnel in OpenStack Mitaka
asked 2016-09-13 06:03:38 -0500
ThomasHammann gravatar image
Dear support,
I am using OpenStack Mitaka running on Ubuntu 14.04 LTS Server. As core plugin ML2 is used together with mechanism driver for Open vSwitch. Installation was done as described in "_URL_ ML2 is configured as Core Plugin, using Open vSwitch and L2Population as Mechnism Driver.
In the ML2 configuration file the mtu size values are configured as follows:
patch_mtu = 1554
segment_mtu = 1554
physical_network_mtus = vlan:1500,external:1500
When creating a physical network type vxlan (neutron net-create....) Neutron calculates the MTU size as a minimum between patch_mtu and segment MTU and finally substracting 50 bytes. The 50 bytes are based by the overhead of the Outer Ethernet Header (14 Byte), Outer IP Header (20 Byte), UDP Header (8 Byte) and VXLAN Header (8 Byte).
Explanation in ML2 configuration file:
# Maximum size of an IP packet (MTU) that can traverse the underlying physical
# network infrastructure without fragmentation when using an overlay/tunnel
# protocol. Either set this to the same value as the global_physnet_mtu value
# or use it to explicitly specify a physical network MTU value that differs
# from the default global_physnet_mtu value. (integer value)
patch_mtu = 1554
Questions:
1.) Why does Neutron not use the configured 1554 Byte MTU size in ML2 configuration file, but substracts 50 Byte, resulting in a insufficient MTU size for VXLAN Networks (in my case of 1504 Bytes)? Why is it not mentioned in the ML2 configuration file, that Neutron substracts 50 byte from the configured patch_mtu/segment_mtu value to inform users about that this important aspect? What's the idea to reduce the patch_mtu value with 50 Bytes?
2.) In case of updating the patch_mtu and segment mtu size in the ML2 configuartion file, tests show, that the new values do not have not any effect to already created networks, but are only effective in case of creating new networks.
I tried to update the already created network, but MTU size is not offered as an option. Is there any procedure, how to update the new patch_mtu/segment_mtu size from the ML2 configuration into already created networks? Restarting the cluster or any process restart does not help. Is it really required to delete and re-create phsical network to adapt an already created network tot he new values from the ml2 configuration?
Thanks a lot for support
Thomas

where did you find this patch_mtu option? I don't see it in the source code.

The additional headers added to the packets may cause the packet to exceed the maximum transmission unit, or MTU. Encapsulating a packet with VXLAN headers or any other headers related to Openstack virtual network may cause the packet size to exceed the default maximum. Connection issues caused by exceeding the MTU show themselves in strange ways; they can be seen in partial failures in connecting to instances over SSH or in a failure to transfer large payloads between instances. Consider lowering the MTU of interfaces within virtual machine instances to account for the overhead of encapsulation is a good solution to avoid weird connectivity issues. I guess this is why Openstack reduces the MTU automatically.

Hello together,
thanks a lot for your support. I am not using the option "dnsmasq_config_file =/etc/neutron/dnsmasq-neutron.conf" in the dhcp_agent.ini file, because the value in the "dhcp-option=26,1400" is used during Path MTU discovery protocol, where DHCP Server would like to assign an MTU value to instances, and my instances (cirros) does not consider PMTU.
Be aware, my issue in not any MTU size value on any instance or subnet, but only the MTU size of the physical network created with the neutron command "neutron net-create..........." with admin priviliges.
When I use in the ml2 file the value path_mtu=segment_mtu=1604 bytes, then Neutron reduces from that value 50 bytes, finally resulting in the expected 1554 bytes, which are required for VXLAN based Overlay Networks. Please see output "net-create ..." command executed with admin rights with path_mtu=segment_mtu=1604 bytes:
root@controller01:~# neutron net-create TENANT_NET100 --tenant-id fe55df4eac9a4f7b9460877e5c30a923 --provider:network_type vxlan --provider:segmentation_id 100 Created a new network: +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | | | created_at | 2016-09-08T14:07:52 | | description | | | id | d2a33db5-c466-4d6e-a22a-eb1e70905007 | | ipv4_address_scope | | | ipv6_address_scope | | | mtu | 1554 | | name | TENANT_NET100 | | port_security_enabled | True | | provider:network_type | vxlan | | provider:physical_network | | | provider:segmentation_id | 100 | | router:external | False | | shared | False | | status | ACTIVE | | subnets | | | tags | | | tenant_id | fe55df4eac9a4f7b9460877e5c30a923 | | updated_at | 2016-09-08T14:07:52 | +---------------------------+--------------------------------------+
When I use instead of 1604 bytes the normal expected value 1554 bytes (path_mtu=segment_mtu=1604 bytes) in ml2 config, then the same output shows 1504 bytes for the physical network, which is unsufficient for VXLAN Over

Background: The incidence of adenocarcinoma of the esophagogastric junction (AEG) has been increasing worldwide. We investigated the clinicopathological characteristics of patients with Siewert type II and III AEGs and clarified the optimal intra-abdominal lymph node dissection in these patients.Methods: This study included 132 patients with AEG who underwent curative resection at Shizuoka Cancer Center from September 2002 to December 2012. We used the index of estimated benefit from lymph node dissection (IEBLD) to assess the efficacy of lymph node dissection of each station. The clinicopathological characteristics and IEBLDs of each station were compared between patients with Siewert type II and III AEGs.Results: We analyzed 92 patients with Siewert type II AEG and 40 patients with Siewert type III AEG. The incidence of lymph node metastasis was high in both groups (64.1 % in type II AEG and 75.0 % in type III AEG). The 5-year survival rates were similar for the patients with Siewert type II and III AEGs, at 54.0 and 53.4 %, respectively. The IEBLDs of stations located near the esophagogastric junction were generally high in both groups, while the IEBLDs of lower perigastric lymph nodes were higher in Siewert type III than in Siewert type II AEG cases.Conclusions: The IEBLDs were similar between Siewert type II and III AEGs at all stations except for lower perigastric lymph nodes. Total gastrectomy should be selected as a standard treatment for Siewert type III AEG, whereas in Siewert type II AEG, preservation of the distal part of the stomach may be an acceptable procedure.

Stop Surviving and Start Living
You were born to thrive!
You can do more than just survive. Because of the price Jesus paid, each believer has been given access to a world of abundance: Heaven itself. For too long, society and even some of the church have believed we are defined by our surroundings-we are what happens to us. This belief has produced a rampant identity crisis. However, once we understand who we truly are and who God truly is, we open the door for limitless living.
In Thrive: Stop Surviving and Start Living, you will learn:
- How to thrive in every circumstance
- How to access Heaven's abundant resources
- The beauty of your new identity
- How to walk as a citizen of Heaven in this life
- How to connect with God and hear His voice
- How beliefs shape the way you live
- How a lifestyle of worship changes everything
According to Jeremiah 17, when we trust the Lord, we become a mighty tree rooted in the rivers of heaven that can withstand even the harshest conditions. We no longer have to rely on the world around us to provide us nourishment-we have been filled with Living Water, the very presence of God, enabling us to stay well-watered in every moment. Stop living a withered life. Tap into the streams of Heaven and start thriving!

Turkey will launch two miniature satellites to space next year, according to a Turkish defense technology company.
STM Defense Technology and Engineering Company aims to develop small satellites, Elif Dirgin, the director of the satellite systems, said at an International Defense Industry Fair (IDEF).
Ergin said the company have already initiated two satellites projects to build a microsatellite named Lagari and a nanosatellite.
"Both satellites are under development process and will be launched to space next year," said Ergin, highlighting that Lagari is the country's first high resolution micro satellite.
Nano and macro satellites are small satellites with mass from 1 to 10 kilograms (2.2-22 pounds). They can be used for space research and do everything a conventional satellite does.
Lagari will be used for observing forests, cultivated areas, natural disasters and general mapping, she added.
She said the company focuses on the constellation since it is an innovative subject.

Linear Potentiometer Crackmeter
The Linear Potentiometer Crackmeter is a robust, high resolution and accuracy instrument designed to measure displacements across cracks and joints in buildings, bridges, dams, pipelines etc. It can measure in expansion and contraction.
The Linear Potentiometer Crackmeter is a highly accurate and robust instrument used to measure displacements across cracks and joints of a structure.
The potentiometer is installed across a crack or joint of the structure to be monitored, using either groutable or expanding shell anchors.
As the crack expands or contracts, the change in the distance between the anchors causes the connecting rod within the potentiometer body to move. The movement of the potentiometer changes the output which determines the movement of the crack with high resolution and accuracy.
- High resolution and accuracy
- Robust design
- Suitable for long-term monitoring
- Suitable for manual or remote monitoring
- Two versions available; Standard (IP67) and Submersible (IP68 to 1700 kPa)
- Accurate, repeatable readings
- Long working life
- Long term stability and reliability
- Connecting cable is strong, screened and flexible
The Linear Potentiometer Crackmeter is anchored to the structure to be monitored with groutable or expansion anchors.
The change in distance between the anchors caused by the crack opening or closing, will cause a connecting rod to move within the potentiometer body, changing the resistance of the potentiometer via a voltage divider.
By reading this change in voltage, the movement of the crack can be determined.
The Linear Potentiometer Crackmeter measures displacements across cracks and joints in buildings, bridges, dams, pipelines and similar structures. It can measure both expansion and contraction of cracks or joints.
Typical monitoring applications include:
- Brick and stone buildings
- Settlement, heave or foundation clay shrinkage
- Bridges and dams
- Construction joints
- Joints and bearing/support interaction
- Tunnels and lining cracks
- Structures susceptible to earthquake and landslide areas

Black and White Photography Exhibit showcases student work
Students, teachers and parents observed the work of Harvard-Westlake (HW) students in an aesthetic black and white photography exhibition in the Arlene Schnitzer Art Gallery in Wang Hall. Laid out before one's eyes was a very pleasing aesthetic of black and white contrasting images, developed using darkroom film techniques during class. The gallery was first presented Tuesday, Dec. 11, during break.
The exhibit featured work of several ninth graders expressing their creativity by using techniques such as using sharp contrasting lines and silhouettes to create striking modern art.
"I'm in Photography 1, so I was trying to understand the contrast between each item and how transparency works on the paper. I knew that I wanted a darker outline, so I used a more solid object to get that contrast, and for the whiter parts of my project, I used a cup that was transparent all the way through, so the light could travel through." Dylan Tatum '22 said.
While discussing what his class is working on now, Tatum said, "For the rest of the semester we're still doing dark room [photography], but we're working on it to a more detailed level, learning how to use double exposure, and stuff like that. For the past month and a half, our work has been camera less."
Overall, the exhibit was a creative expression of HW students art. A darkroom is a completely dark room, where black and white prints are commonly made, while a safelight is commonly used to illuminate the work of the area. Students are encouraged to explore while developing craft and composition.

"The Best Poster on the Advantages of Rainwater Harvesting"
The Raindrops Geneva Award is an art competition organised by the IRHA to promote Rainwater Harvesting and to increase public awareness on the importance of this topic.
For the fourth edition of this competition we looked for posters that illustrate the uses and/or benefits of rainwater harvesting.
The International Rainwater Harvesting Alliance is pleased to announce that the jury, chaired by Mr. Christian Rümelin (Chief Curator, Graphic Arts Department of the Arts and History Museum, Geneva) and made up of Mr. Jérôme Baratelli (Head, Visual Communication Department, HEAD Art & Design School, Geneva), Mr. André Klopmann (Vice Secretary, Chancellerie, Geneva), Mr. Alain Dick (IRHA, President) and Ms. Vessela Monta (IRHA, Executive Director), have now reached a decision and selected the three posters that best illustrate the uses and benefits of rainwater [cf. Rules of the Competition].
With over 750 submissions of very high quality entered from 77 different countries, selecting just three posters was not an easy task. All posters were reviewed carefully following a set of criteria specified in the Rules of the Competition and supplemented by the jury:
- The force and artistic value of the message, including technical and aesthetic considerations;
- The expression of the advantages of rainwater harvesting for mankind and nature;
- The pertinence of the presented experiences/examples of rainwater harvesting;
- The format: graphically speaking does this submission work as a poster.
The selection process was conducted as follows:
- All posters were saved anonymously* into one file.
- Out of all posters, 125 posters were preselected, using the above mentioned criteria. Any posters not matching the requirements stated in the Rules of the Competition were automatically excluded.
- The Jury discussed the remaining 125 posters: the jury reviewed the posters left in the competition and were able to reduce this figure by selecting those that stood out round after round. After long hours of debate, the overall number of 750 posters was reduced to just 15. It was decided that all 15 posters would be printed and presented at the Raindrops Geneva Awards 2013 Exhibition that will be held for a week on 21st March 2014 in the World Famous Courtyard of the Geneva Town Hall, with the support of the Republique et Canton de Genève.
- Selection of the three winning posters: A handful of posters clearly stood out and were voted on by the members of the jury. Each member of the jury was allowed three votes. The winning posters were those that received the majority of votes.
IRHA congratulates the following three winners:
1st Prize (1'000 CHF): Kateryna Korniienko-Heidtman for "Rainwater Use for Life"
2nd Prize (600 CHF): Eva Kay Norrington for "Smallest of Gestures"
3rd Prize (400 CHF): Jason Holmes for "0.3%".
The authors of the 13 posters shortlisted for the exhibition also deserve a huge congratulation:
- Nelu Wolfensohn for "Rain Drops, Life Drops"
- Francesca Reinero for "Rainwater is a free asset, use it"
- Anna Zima for "Life in every Drop"
- Pash Bolshakov for "The Perspective"
- Seyyedmehdi Mousavi for "Efficiency"
- David Walton for "Raindrops"
- Charlie O'Connell for "Rainwater Harvesting can turn your Life Around"
- Mikolaj Dobrucki for "Lower Price – Better Quality"
- Svetlana Tarasova for "Save Rainwater for your Washer"
- Tanya Krendel for "Raindrops create the Life Around Us"
- Zuzanna Chanska for "Water your Life with Rain"
- Marc Baker for "Baker_01".

. As an example, if your distribution list contained 350 email addresses, 4 emails would be sent, the first 3 having 100 BCC recipients, and the last email with 50 BCC recipients.The default value of this property is YES.
top
SizeLimit
@property (nonatomic, copy) NSNumber *SizeLimit;
The MailMan will not try to retrieve mail messages from a POP3 server that are greater than this size limit. The default value is 0 indicating no size limit. The SizeLimit is specified in number of bytes.
top
SmtpAuthMethod
@property (nonatomic, copy) NSString *SmtpAuthMethod;
This property should usually be left empty. The MailMan will by default choose the most secure login method available to prevent unencrypted username and passwords from being transmitted if possible. However, some SMTP servers may not advertise the acceptable authorization methods, and therefore it is not possible to automatically determine the best authorization method. To force a particular auth method, or to prevent any authorization from being used, set this property to one of the following values: "NONE", "LOGIN", "PLAIN", "CRAM-MD5", or "NTLM".
Note: If NTLM authentication does not succeed, set the Global.DefaultNtlmVersion property equal to 1 and then retry.

A bio-impedance probe to assess liver steatosis during transplant surgery.
This work addresses the design of a bioimpedance probe to assess steatosis on the exposed liver in the donor during liver transplant surgery. Whereas typically bioimpedance uses needle probes to avoid surface effects, for clinical reasons a non-penetrative probe is required. In addition the need to ensure that the measurement is representative of the bulk tissue suggests a larger probe than is normally used to ensure a sufficiently large measurement volume.

It is not known when Brigus was settled. Some people believe that is was settled shortly after Cupids but we don't know much about it before the first census of Newfoundland was compiled in 1675. The origin of the name Brigus is unknown. One theory has it coming from the town names of Brickhouse or Brighouse, in Yorkshire, England. Another has the name coming from the French word for intrigue or plot, "Brigue."
Sir John Berry's census of 1675Â lists 34 people living in Brigus, with three fishing rooms in operation. Two years later, the Poole census showed three families operating five fishing rooms, as well as raising cattle and pigs.
Captured by the French
In 1697, Brigus was captured and burned by the French under Pierre Le Moyne d'Iberville. The French did not want residents of Brigus to escape to Carbonear Island, which had been fortified. Houses at Gallis Cove and Riverhead were burned. Legend has it the French were on their way out of the harbour when they heard either a crowing rooster or a barking dog in Frogmarsh where other houses were hidden by the trees. They returned and burned the seven houses.
AbbĂ© Baudoin's Description
At this time AbbĂ© Baudoin, the priest who accompanied d'Iberville, reported that Brigus "was a well established English settlement, where there were about sixty men." He said the French found 6000 salt cod fish stored at Brigus.
In March 1705, a French force commanded by Jacques Testard de Monigny burnt Brigus a second time. However there were no lasting effects on the community. The war ended in 1713 without any further attacks. The community prospered and went on to become a successful sealing and fishing port.
Today Brigus is a very popular destination for tourist, who enjoy its quaint peacefulness and its beautiful scenery.

By the tap hole with the ironworker
What sort of grunting noises does the furnace in the Landscape Park make when pig iron is being produced? What blooming surprises do you think you're in for when you set off to explore nature in the park? What happens if the furnace gets a sore "throat"? The guided tours through the Landscape Park are as varied as the former ironworks itself.
Whether it's through the Parklands or the area around Blast Furnace 5 and high up to the viewing platform – a guided tour through the Landscape Park will show you a piece of living industrial and cultural history.
Part of that living history is, for example, the fact that former ironworkers regularly come here to meet up with the Blast Furnace again. Standing in front of the Blast Furnace's run-off chute they talk to visitors about the hot working conditions and give an insight into an ironworker's life. It's especially on the torchlit guided tours at weekends that the works once more gives off a fiery glow just as it did thirty years ago. But please note – on the evening tours a torch is essential!

Above: Bulker with wind sails MV Pyxis Ocean started testing the wing sails in August 2023 (photos courtesy of Cargill)
Cargill Ocean Transportation, the ocean shipping arm of the commodities giant, is reporting encouraging results largely in line with projections after the first six months of testing of wind-assisted propulsion aboard a Kamsarmax bulker. Data from the Pyxis Ocean (81,000 dwt) will be used according to Cargill to inform the potential scale-up across the fleet and industry as well as providing learning to further improve the design, operation, and performance of the solid sail technology.
After a partnership that began in 2019 to develop the wind technology, Cargill working with UK-based start-up BAR Technologies moved forward with the first installation of the sails on the 751-foot (229 meter) vessel completing the work in Shanghai in August 2023. The vessel built in 2017 was retrofitted with two 150 feet (37 meter) rigid sails made of a compositive material not unlike the blades for wind turbines.
During the first six months, the vessel which is owned and operated by MC Shipping, a division of Mitsubishi, has completed three voyages. It crossed the Indian, Pacific, and Atlantic oceans, sailed around Cape Horn and the Cape of Good Hope, and encountered all types of weather.
BAR Technologies and Cargill estimated the vessel would achieve an annual average saving of three tonnes of fuel per day, which equates to 11 tonnes per day of CO2 on a well-to-wake basis. This equates to roughly a 14 percent saving for the Pyxis Ocean and they report in the first six months the vessel has been within 10 percent of predictions. During optimal sailing conditions, the Pyxis Ocean achieved a saving of more than 11 tonnes per day in fuel consumption which translates to 41 tonnes per day less CO2 emitted well-to-wake or a 37 percent emissions savings.
"We are encouraged by the results and have learned a great deal about implementation wind-assisted propulsion on dry bulk vessels," said Jan Dieleman, president of Cargill's Ocean Transportation business.
The technology is controlled by a touch panel on the bridge and fully automated once the sails are raised. They can be folded down for safety and securing handling as well as during port arrival, departure, and operations. When deployed, sensors constantly measure the wind, and the sails self-adjust to the optimal configuration.
Captain Suraj Vaidya of the Pyxis Ocean highlights that the concept is to lower the engine power using wind energy to maintain speed at lower power and fuel consumption levels. He also recounted a unique use of the sails when they were monitoring a North Atlantic storm.
"We deployed our sails and were able to capitalize on that strong wind coming from Canada," Captain Vaidya recalls. "We outsailed the storm. On a different ship, the voyage to the English Channel would have taken an extra day or more. With the sails, the Pyxis Ocean maintained very good speed and safely entered the English Channel just ahead of the storm."
The early voyages have provided insight into more than just the application of the sails on a vessel, it has also highlighted broader logistical challenges in the global maritime system. Given that every port, terminal, and berth is different, the companies said their involvement is critical towards integrating Wind Assisted Propulsion (WAP) technology into the global maritime system on a wider scale. Cargill says it has worked with more than 250 ports worldwide calling the response encouraging.
"The results of the Pyxis Ocean's first voyage with WindWings installed clearly demonstrate that wind-assisted propulsion can secure significant fuel savings and emissions reduction," said John Cooper, BAR Technologies CEO. He explains that while the Pyxis Ocean has two WindWings, they anticipate the majority of Kamsarmax vessels will carry three wings, further increasing the fuel savings and emissions reductions by a factor of 1.5.
Cargill will continue the testing and experimenting of operational, technical, and commercial aspects of the Pyxis Ocean to incorporate the maximum amount of learning into the potential design of future installations before scaling up.
