The ones you ask us most often!
Do you ship les huilettes in Europe?
You can buy from www.ohmycream.com : they ship worldwide.
This includes postal charges and all the attention we have paid to the preparation of your package. Do not hesitate to add a second huilette to your basket... the shipping costs for France are free for two products!
I have just received mon huilette Day or mon huilette Night, and the bottle does not seem enough filled ... From one bottle to the other, the level may vary but be reassured, there is always 15ml of serum-oil in your bottle. It is just that our bottles may have slight differences in the thickness of the walls, which has an impact on the level of filling of the bottle.
I had trouble spreading mon huilette Body, what is the application ritual?
Place three or four pressures of mon huilette Body in the palm of your hands, inhale deeply to take advantage of the psycho-sensorial benefits of essential oils, heat mon huilette Body in between hands, then apply after shower on wet skin.
Take advantage of it to perform a gentle massage, on the thighs, legs and upper body. This massage will leave your skin nourished - you just have to wait a few minutes before you dress.
There is a white deposit in the bottle of mon huilette Cleanse ?
mon huilette Cleanse is formulated with virgin coconut, jojoba and olive vegetable oils. These specific oils freeze when the temperature drops below 10-15°C, a phenomenon that occurs frequently in winter. This phenomenon does not affect the quality of mon huilette Cleanse. Little trick to regain transparency? Immerse mon huilette Cleanse in a glass jar filled with hot water about ten minutes (bain-marie) or put it under hot tap water until the deposit dissolves.
What precautions should I take to make mes huilettes travel?
Remember to screw the cap of mon huilette, if a little oil has remained on the edge of the collar, there may be a mechanical effect that automatically "unscrews" the cap ... So better to check twice! We also advise you to place your huilettes in a small plastic bag if you fly to make sure you do not stain your clothes.
I am pregnant, can I use les huilettes?
Les huilettes are synergies of essential and vegetable oils. Essential oils are very active raw materials so it is better to apply the principle of optimal safety. During pregnancy, favor synergies 100% vegetable oils. We therefore forget essential oils during the time of this magic moment to better find them later ... idem during breast feeding, essential oils penetrate the skin and can end up in breast milk ... so we forget too!
Are les huilettes suitable for children?
A precautionary principle avoids giving essential oils to children under 7 years of age. At the same time, les huilettes are comprehensive anti-aging care :) but ... mon huilette Day is also suitable for teenagers if no particular skin problem, mon huilette Night is a smoothing care - so not a priority among young people, mon huilette Body is suitable for youngers and elders alike to nourish dry skin.

Tom Hiddleston wasn't kidding when he said that he wore Captain America's suit in Thor: The Dark World, and now we have a video which proves it!
Empire Magazine has released a video where Loki plays Cap, and this time is not Chris Evans doing the cameo as in the film, is Tom Hiddleston! The actor perhaps did it for fun, it's a very iconic moment, or maybe he did it to show Chris Evans how to play Loki playing Captain America. Okay, blown mind!
I didn't know this version of that scene existed. That's a decent American accent he has at the end there.

No. 6 Wichita State overpowers College of Charleston 81-63
WICHITA, Kan. (AP) — Wichita State coach Gregg Marshall was anxious to get a look at the play by play after his No. 6 Shockers defeated College of Charleston 81-63 on Monday night.
He wanted to know exactly what time things went south after Wichita State built a 33-point lead.
"So it was 9:06 left," he said. "We were up 33 with nine minutes left and got outscored 26-11 after that. Those last nine minutes were horrible."
Fortunately for Wichita State (2-0), the Shockers' big men dominated prior to that. Center Shaquille Morris had 18 points and 10 rebounds in just 22 minutes. Fellow senior post players Rauno Nurger (16 points) and Darral Willis (14 points) also found success inside, helping Wichita State to a 44-27 rebounding advantage.
Shockers starting guards Landry Shamet and Conner Frankamp each scored 10 points.
Grant Riller had a game-high 20 points for College of Charleston (1-1). He scored 18 of those in the second half on 7-of-10 shooting.
Joe Chealey added 14 points for the Cougars.
Wichita State led 47-22 at halftime, outscoring Charleston 22-2 in the paint.
The Cougars went just 5 of 23 from the floor in the first half. Willis and Morris combined for 24 first-half points.
"Shaq was great tonight," Marshall said. "When he has energy, he is so nimble and skilled. We saw that again in this game."
Wichita State scored 23 points in the first 11 minutes of the second half before, Marshall said, "We got off the gas and couldn't get it back."
Riller scored inside and outside, helping Charleston shoot 14 of 28 in the second half.
"I liked what we did in the second half," Cougars coach Earl Grant said. "From a physical standpoint and from a rebounding standpoint, we settled down."
Grant spent six seasons as an assistant to Marshall, three at Winthrop and three at Wichita State. Cougars director of basketball operations Matt Braeuer played at Wichita State and was the starting point guard on the Shockers' 2006 Sweet 16 team.
"We ran some of the same stuff," Grant said. "They just ran it better."
FREE TO SCORE
Wichita State went 18 of 22 from the free throw line. That's almost identical to its performance in the season opener, when it went 18 of 23 against Missouri-Kansas City.
That gives Wichita State an 80-percent free throw percentage. The Shockers shot 73.3 percent last season.
BIG PICTURE:
College of Charleston: The Cougars were still without Jarrell Brantley, a preseason All-Colonial Athletic Association selection, due to a knee injury. But they outscored Wichita State in the second half to make it respectable.
Wichita State: Facing a significantly better defense in its second game, Wichita State's offense was still overpowering at times despite the absence of last season's leading scorer, Markis McDuffie. He is out another month with a stress fracture in his left foot.
College of Charleston: The Cougars play Saturday night at Charlotte before heading to the Great Alaska Shootout.
Wichita State: The Shockers have a week to prepare for the Maui Invitational. Wichita State's first game will be Nov. 20 against California.

Home » Information & Articles » Oxygen Transfer Rates, SOTR & Pumping Rates of Aeration Systems
How much oxygen is your aerator really going to deliver and what is the pumping rate.
Aeration systems make claims about the oxygen transfer rate and how many pounds or kilograms of oxygen are added per hour or per kilowatt. This can be a very effective way to compare the efficiency of an aeration system based on the biological oxygen demand of the system.
A small pond with trout or bass will have a different BOD (biological oxygen demand) compared to a wastewater treatment system. In some cases a bottom mounted diffuser aeration system can be the most efficient choice but in other applications a large surface paddlewheel aerator might be required to meet requirements.
Standard Oxygen Transfer Rates
Most commercial-grade aerators and diffuser systems have been laboratory tested to determine their SOTR (Standard Oxygen Transfer Rate) but the resulting SOTR ratings are based on fairly narrow criteria usually when test water has zero dissolved oxygen and at a defined temperature.
In real world applications the advertised SOTR can almost never be expected because the actual rate of oxygen transfer is temperature and existing D.O. (Dissolved Oxygen) concentrations. Any aerator or diffuser will only provide its measured (advertised maximum) oxygen transfer rate when the dissolved oxygen levels in the water are at zero or close to zero.
This chart will help estimate the actual oxygen transfer an aerator will give when there is already oxygen in the water.
For example: If the water temperature is 59°F (15°C) and the dissolved oxygen level is 3 Parts Per Million (PPM) or 3 mg/l, an aerator system or diffuser that is rated at 3 pounds of oxygen per hour will really only provide 64% of the advertised SOTR or around 1.92 pounds of oxygen per hour (3 lbs x 64 percent = 1.92 lbs).
If the pond temperature is 77°F (25°C) and the dissolved oxygen level is 5 Parts Per Million (PPM) or 5 mg/l, an aerator system or diffuser that is rated at 3 pounds of oxygen per hour will really only provide 35% of the advertised SOTR or around 1.05 pounds of oxygen per hour (3 lbs x 35 percent = 1.05 lbs).
Percentage of advertised oxygen transfer actually transferred to a pond based on water temperature and the dissolved oxygen level prior to adding the aeration device.
Dissolved Oxygen Level
in Water Being Aerated (mg/L or PPM)
If a pond temperature is 68°F (20°C) and the dissolved oxygen level is 7 Parts Per Million (PPM) or 7 mg/l, an aerator system or diffuser that is rated at 3 pounds of oxygen per hour will really only provide 19% of the advertised SOTR or around 0.57 pounds of oxygen per hour (3 lbs x 19 percent = 0.57 lbs).
Low oxygen concentrations can be damaging to a variety of critical life stages of aquatic animals, including larval invertebrates, and fish eggs and fry.
Like temperature, organisms differ in their tolerance to low dissolved oxygen levels.
The ideal dissolved oxygen level for fish is between 7 and 9 milligrams per liter (mg/L); most fish cannot survive at levels below 3 mg/L of dissolved oxygen.
Some published guidelines suggest dissolved oxygen concentrations must not decline below 5 mg/L and should not average less than 6.5 mg/L over a seven-day period. However, the guidelines also require that dissolved oxygen concentrations remain above 9.5 mg/L in areas where early life stages of aquatic biota, particularly fish, are present.
Anoxic (depleted oxygen) conditions can result in fishkills, which is particularly common during harsh winters with extended ice-cover.
When fish are not a concern such as a wastewater treatment facility or leachate pond, where the main concern is to ensure the BOD is adequately addressed by the chosen aeration system, different criteria will apply and take a priority role in importance when deciding if bottom diffusers, surface aerators or some sort of jet or aspiration aerator or paddlewheel type aerator will make the most sense.
Diffused Air Aerators Systems
These aerators are also called lake-bed aerators or bottom-mount diffusers and basically use a shore-mounted air blower or compressor type air pump to push air into multiple diffusers placed at the bottom of a pond, lake or wastewater tank.
Diffused bottom aeration is probably the most common form of aeration in ponds and lakes and can also be effective in wastewater basins and holding tanks. Air is forced through a diffuser system which breaks up the airflow into bubbles. Depending on the matrix or make-up of the diffuser the bubbles will be fine bubbles less than 0.5 millimeters in diameter or more coarse bubbles above 2 millimeters
Some of the more popular aeration systems in North America harness the efficiency of the disc diffusers as part of their bottom mount, or lake-bed, diffuser system. Diffuser discs come in various sizes; the most common sizes are the 9 inch diffuser disc and the 12 inch diffuser disc. These diffuser discs can be arranged on proprietary weighted bases according to manufacturer or individually weighted or affixed via lengths of weighted airline to mainline header systems with valves tapped-off a main header. Diffuser discs have an integrated check-valve system to prevent backflow of liquids into feeder lines.
Fine Bubble diffuser discs membranes are made of EPDM (ethylene propylene diene monomer), silicone or PTEE (PolyTetraFluoro Etyhylene) layered combinations. Lake and pond diffuser assemblies typically use EPDM diffuser discs as they are generally used in fairly benign, low-organic situations in fairly clean waters so they are able to resist fouling quite well. Wastewater systems, leachate ponds, compost reduction basins or storm water retention ponds often have higher levels of organics and dirty effluent which can cause issues with these diffusers and a more specialized diffuser is needed.
Establishing a SOTR (Standard Oxygen Transfer Rating) rating for a diffuser device or to pinpoint a precise SAE (Standard Aeration Efficiency) for a bottom mounted or lake-bed diffuser aeration system is not easy.
The SAE (Standard Aeration Efficiency) of air diffusers is generally between 0.5 and 1.5 pounds per horsepower per pound (1.0 - 2.0 lb/O2/hp-hr). High efficiency air stones which can create finer bubbles have higher SAE closer to 3.0 pounds of oxygen per horsepower per hour. Understanding the needs of your aquatic system will help you best choose the diffuser system that will be most cost-effective for your project. Depth of the diffuser placement will dictate the PSI (Pounds per Square Inch) requirements of your compressor or blower. Compressors and blowers have limited airflow and pressure thresholds and tubing lengths can further impact the final diffuser performance. In deeper ponds and lakes over 10 foot depth the best aeration efficiency and oxygen transfer will be with a bottom mount diffuser system. Rotary vane or piston compressors can provide adequate airflow in the most common situations and if higher airflow and pressure is necessary then a rotary screw compressor. It is important to recognize and understand the differences between reciprocating, carbon vane, rotary centrifugal, regenerative blower and rotary screw compressors as they all have specific strengths and weaknesses.
To maximize the efficiency of a diffuser system and to get the most pounds of oxygen per horsepower per hour from the diffuser you need to ensure the air blower system is tailored to your specific job.
One interesting benefit of using land-based blowers or air compressor systems for pond aeration is the reduced underwater noise levels of diffuser systems when compared to surface aerators. More and more research is focused on understanding the impact of extraneous noise on aquatic creatures. Measurements conducted under water are raising red flags about the noise produced by devices such as paddle wheels, agitators, airlifts and drilled pipe homemade DIY diffusers or spargers. In non-living systems (cement basins or oil field tailing ponds) this extraneous noise is not an issue.
Another benefit of bottom-mount diffusers, because the air supply blower or compressor is onshore and often hundreds of feet from the diffuser, is that there is much less audible noise in the water column to disrupt fish or aquatic life. Reducing the noise that is pushed into the pond through an aeration device can improve the health of the fish stocks and general well-being of the pond. Some pond and lake owners, especially fish clubs or conservation groups have reported that diffused air is the only aeration method they can use that will not disrupt breeding. The situations and considerations are virtually endless, so take some time to research the best aeration method for your particular application beyond looking at the Oxygen Transfer.
Pumping Rates of Diffuser Aeration Systems
One of the most popular ways of comparing diffusers is to use the pumping rate of the diffuser based on the CFM airflow (cubic feet per minute) through the diffuser at different depths. Diffusers will circulate more gallons per minute as the depth of the diffuser placement increases even with the same CFM flow. By measuring the Gallons Per Minute of pumping it is possible to establish how many diffusers are required and the CFM needed to circulate a given volume of water.
Establishing concrete results is not easy. Testing of diffusers is often paid for by the manufacturer of the system and the data released are usually the results that show the product in the best possible light featuring the highest oxygen transfer rates and the best aeration efficiency
Gallons Per Minute Pumping Rate
Based on listed CFM airflow per diffuser and depth of diffuser
Diffuser Style
(2 m)
One x 9" EPDM Diffuser Disc (1 CFM)
Four x 6" Silica Airstone Assembly (2 CFM)
Six x 9" Silica Airstone Assembly (3 CFM)
Increasing the CFM will increase the pumping capacity of the diffuser but every diffuser type has limitations and backflow headloss equations to consider. Wastewater and tank diffusers are not considered in this chart as they are more specialized. This chart should be used as a general guide only without scientific acknowledgment or reference. Data is condensed estimations based on manufacturer claims.
See our selection of Aeration Diffusers | Air Compressors
If a diffuser placed at 5 foot depth is rated to pump or circulate 500 gallons per minute with airflow of 2 CFM, the same diffuser at a depth of 12 feet might have a pumping capacity of 1500 gallons per minute with the same airflow of 2 CFM. This is why bottom mounted, lake-bed diffusers are typically used in deeper situations.
If you need to aerate a large pond that has 2.3 million gallons (approximately an acre sized pond average 7 feet deep) and you want to do a complete turnover of the total pond volume every 24 hours, you need to look at the pumping rates of your chosen diffuser at depth and determine how many diffusers will do the job.
If each of your diffusers has a rated pumping capacity of 1000 Gallons Per minute with 2 CFM (Cubic Feet per Minute) of airflow then that single diffuser would theoretically be able to do a complete pond turnover in around 38.5 hours. (2,300,000 gallons divided by 1000 gallons per minute = 2300 minutes = 38.3 hours to pump 2.3 million gallons).
If you used two diffusers for a total pumping capacity of 2000 gallons per minute you would be able to do a full volume mix of the pond in 1150 minutes or 19.2 hours. If you used three diffusers for a total pumping rate of 3000 gallons per minute you could do the complete pond turnover in 767 minutes or 12.8 hours. So with three diffusers and 6 CFM you can pump the full volume of an acre pond in close to 12 hours.
Keep in mind that the depth and shape of your pond will have an impact on total pumping rates and just how thorough the mixing of the pond is; stagnant pools can exist in ponds where the water won't be moved unless correct placement of the diffuser takes these dead zones into account.
Smaller bubbles are better bubbles
Let's have a brief lesson in fine bubbles, it will be fun (well...not exactly) and you will get a short course in why smaller is sometimes better especially when it comes to diffuser bubbles!
Lesson 1 - Let's take a fairly large bubble as far as aeration goes. Our large galloping bubble that is 0.8" in diameter, just over 3/4 of an inch, or 20 mm has a full volume of 1.64 cubic inches or 4.19 cubic centimeters. This same glorious orb has a surface area of 5 inches or 12.6 square centimeters and that is what we can define as a coarse bubble!
Lesson 2 - Now a coarse diffuser like an airstone would create large bubbles like in lesson one but if we could use the same volume of air but break that large sphere into smaller ones we could greatly increase the available surface area which in turn enhances and embellishes the aeration transfer capacity of the same air volume! If we replaced that one large 3/4" wide bubble with tiny bubbles or micro-bubbles that were 1/16 of an inch or 3 mm in diameter we could fit 296 of these fine bubbles into the larger one of lesson 1! The combined surface area of those 296 bubbles works out to over 33 square inches or 84 square centimeters! This is close to 7 times the total surface area...and the surface is where the oxygen transfer occurs.
Lesson 3 - Now since the surface area is close to 7 times greater we can theoretically aerate 7 times as much water with the same compressor or blower or air pump depending on whether we have a fine bubble diffuser or a coarse bubbler. Same air pump, totally different efficiency!!
Surface Aerators
Surface aerators usually consist of a submersed motor suspended from a float that drives an angled prop to create a frothing oxygen transfer boil on the surface. In smaller ponds and aquaculture tanks these are often retail units between ½ HP and 5 HP. Larger models up to 300 HP are used by commercial applications and wastewater treatment. A basic calculation for oxygen transfer requirements or inadequate surface aerator is to allow at least ½ HP of an efficient surface aerator for every million gallons of pond volume. This is only a guide used in smaller ponds. High density fish ponds or ponds with a higher BOD should calculate at least ¾ HP per million gallons.
The most efficient small-scale surface aerators will have an oxygen transfer rate based on standard aeration efficiency (SAE) of 3 pounds per hour per horsepower. This oxygen transfer rate will depend on motor efficiency and important factors like pond depth and temperature. As we see in the chart below, a manufacturer's listed oxygen transfer rate of 3 pound per hour per horsepower will depend on the starting oxygen rate (either PPM or mg/litre) of the water. If this surface aerator is put into a pond that has an existing Dissolved Oxygen (D.O) rate of 5 PPM or 5 milligrams per litre and the temperature of the water is 59 degrees F (15 degrees Celsius) the actual oxygen transfer rate of the quoted 3 pounds per HP per hour aerator will only be 46% of the listed efficiency or 1.38 pounds of oxygen per hour per horsepower (HP).
The pumping rates of surface aerators and fountains are usually somewhat lower than bottom diffuser systems. A typical medium sized surface aerator from 1 to 7.5 HP which uses a propeller system and a float will circulate anywhere from 200 to 3000 gallons per minute. The energy required to run a 7.5 HP surface aerator to move 3000 gallons per minute would be more than would be required for a diffuser system which might be able to move the same volume of water with a 1/3 HP air pump and three diffusers.
A surface aerator would be a poor choice for a large or deep pond. It will continue to pump basically the same water over and over again, adding no oxygen where it is needed, because it is not moving water away from the aerator. Paddlewheels or aspirator type surface systems would be better suited when the movement of the oxygenated water away from the aeration device is important.
For the smaller scale surface aerator we use Kasco Marine surface aerators or Aquamaster Surface Aerators or Scott Aerators or any of the many popular retail brands.The typical application include commercial aquaculture, agricultural ponds, industrial plants, municipal waste water and backyard ponds. These units are typically selected for surface aeration when a decorative fountain pattern is neither necessary nor desired, many pond aerators are self-contained, lightweight units that float at the surface with a single power cord returning to shore and two or three mooring lines anchoring the unit. The units are easily installed and maintained by a single person and have proven to be an excellent choice for both continuous duty pond and lake aeration and supplemental aeration for unique applications.
Paddle Wheel Surface Aerators
Paddlewheel aerators are surface aerators consisting some sort of motor, electric, diesel, gas powered or tractor power takeoff that is attached to a floating structure and paddles attached to the motor hub or shaft which spin and splash at the water surface to create aeration. By increasing the diameter of the paddles the oxygen transfer rate can be increased; other important variables are the specific depth of the blades as well of the angle of the paddles. By increasing motor speed and hub rotation the oxygen transfer rate is also incrementally enhanced.
A tractor powered takeoff (PTO) can have very high SOTR (Standard Oxygen Transfer Rate) as much as 90 pounds of oxygen per hour which means they can be important as an emergency aeration supply but the drive-train and drive-shaft of such systems drain efficiency and they are not at all energy efficient beyond emergency aeration. The more efficient three-phase or 3-phase power paddle wheel aerators have a SAE of between 3.5 and 6 pounds of oxygen per HP per hour. This high SAE, combined their ability to de-stratify through rapid circulation makes this type of aerator very popular with aquaculture around the world.
Aspiration and Jet Aerators
This is another surface mounted aeration device that is very good at adding aeration and circulation to a pond or basin. They use a submersed propeller that creates a vacuum effect and draws air through intake ports into a hollow shaft that is dispersed in a large plume of fine bubbles (about 2 mm in diameter) throughout the water. The angle of attack can be adjusted with simple altering of the float brackets. The aspiration propeller aerators are extremely quiet as there is no water boil at the surface like a standard surface aerator; all of the mixing is below the surface. Motors can range from 1 to 100 HP and above. Multiple units can be deployed in basins to ensure there are no stagnant dead spots. This creates a flow linkage that disperses and mixes the oxygen evenly through the pond and ensures an effective circulation. The SAE is approximately 2.0 - 3.0 LB/O2/hp-hr.
Using a dissolved oxygen meter is the most accurate way to ensure your pond is getting the oxygen it requires to remain healthy.

Amongst quite possibly the most frequent electrical wiring concerns is on how to wire a switch. Though applying switches in your own home is kind of quick, wiring one particular might not be that quick for everybody. An ON-OFF switch is definitely quite simple to wire. You can find different kinds of switches, but for this instance, let us say you are setting up a single-pole toggle switch, a very prevalent change (as well as most basic).
There are a few shades of wires inside a regular single-pole toggle switch: black, white, and environmentally friendly. Splice the black wire in two and connect them on the terminal screws - 1 on top along with the other about the bottom screw in the switch. The white wire serves being a source of uninterrupted energy and it is usually connected into a mild colored terminal screw (e.g., silver). Join the environmentally friendly wire to your ground screw of one's swap.
These ways would commonly be sufficient to help make a typical swap perform with out a problem. Nonetheless, should you will not be assured that you simply can achieve the job adequately and securely you much better permit the professionals do it alternatively. After all, you will find a cause why this undertaking is without doubt one of the commonest electrical wiring thoughts questioned by most people.
For many rationale, the way to wire a ceiling fan can be amongst one of the most prevalent electrical wiring issues. To simplify this task, you may use a single change for your single ceiling fan. To wire the admirer, it truly is just a subject of connecting the black wire with the ceiling fan into the black wire of your change. When there is a lightweight, the blue wire really should be related to your black wire of the switch likewise.
There are actually factors why they're the most usually asked electrical wiring inquiries. A person, many imagine it is uncomplicated to complete, and two, these are typically the widespread electrical tasks at home. But then you really shouldn't place your security at risk with your aim to save money. The stakes could even be significantly higher in case you try and save money and do an electrical wiring position with out sufficient know-how or working experience.


This is entirely up to you. Below are some suggestions, we are happy to go through these with you, to help you decide what is best for YOU.
As a wake up call: What better way to wake up than to the music of the great highland bagpipes. The Queen has her own personal Piper for a wake up call when she is visiting Balmoral.
Out of the house and into the car: Let your neighbours know that your big day has arrived in style, the volume of the pipes will certainly draw their attention to the fact that you are about to travel on the journey to the rest of your life.
As Guests arrive at Church/Register Office/Hotel: A nice welcome for your Wedding guests which helps put them in the mood for proceedings.
Piping the Bride on arrival at the service: Hear the buzz of the pipes as you car nears the wedding venue and the excitement builds. Perhaps have your own personal piper lead your car along the final 100 yards on walk you to the church.
Piping the Bride up the aisle: The must among many brides. It is our delight to play as all eyes gaze on as you make the most important walk of your life.
Signing of the register: Have the piper in the background playing a few sweet Scottish Airs as you sign the Wedding Register.
At the church door: Announce your arrival to the world as man and wife to the sound of the pipes for that grand exit.
As the happy couple leave the service by car: This is a very happy moment, with the couple being covered in confetti, the piper can be playing some brisk cheery marches to add to the moment.
Welcoming guests to the reception: Your guests will certainly know where the doors to your reception are when they see the piper standing at the entrance to the hotel playing a few welcoming tunes.
Playing during the Photographs: few tunes to keep your guests entertained as they wait patiently for all the family photographs, the piper will play away in the distance.
Pipe newly weds to the top table: "Ladies and Gentlemen will you please be upstanding for the New Mr and Mrs (your name)" What better entrance can you have than to be accompanied to your seats by a piper, the audience will clap you to the beat of the tune all the way to your seats.
At the cutting of the cake: This may happen prior to the dinner. The piper will pipe you to the cake, will stand still as you cut the cake and pictures are taken, and then pipe you to your seats before marching out of the room.
During the evenings entertainment: Have the bagpiper play for a few mins after the buffet, this helps break your evening up and gives the band or disco a rest. The piper will really keep your guests happy with popular and modern melodies, any tune requests would be discussed at the time of booking.


The Pork Farms team recently took a trip down to London to host the penultimate board games event in the run up to our 2017 grand final.
The Owl & The Pussycat in Northfields was the battle ground for some of London's top journalists and lifestyle bloggers, as contestants took to the boards to compete for the UK'S 2017 Board Games "Media Champion" title.
After a close fought battle, over five different games, the winner of our media contest was Laura Hartley from @WhatsHotblog.

Q: Overlay filled semi-transparent contours I'm trying to find the contours of an image and overlay them (with some transparency) over another image. However, when I execute the following code I get an undesired effect (see image below).
img = cv2.imread('image1.bmp',cv2.IMREAD_GRAYSCALE)
contours, hierarchy = cv2.findContours(img,cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE)

im = cv2.imread('image2.jpg')
im_copy = im.copy()

for j,cont in enumerate(contours):
    im_copy = cv2.drawContours(im_copy, [cont], -1, (0, 0, 255), -1)
    im = cv2.addWeighted(im_copy, 0.4, im, 1 - 0.2, 0)
    im = cv2.drawContours(im, [cont], -1, (0, 0, 255), 0)

cv2.imwrite(f'projects/{prj.name}/logs/repeated_img/{file}', im)

I call drawContours() twice to obtain a semitransparent fill and a solid border. Apparently, one of the contours appears to be more opaque than the other. I suspected that the drawContours is called twice for the same contour, so I tried the following change:
    im_copy = cv2.drawContours(im_copy, [cont], j, (0, 0, 255), -1)
    im = cv2.addWeighted(im_copy, 0.4, im, 1 - 0.2, 0)
    im = cv2.drawContours(im, [cont], j, (0, 0, 255), 0)

Which produces the following error when trying to draw the second contour:
(-215:Assertion failed) 0 <= contourIdx && contourIdx < (int)last in function 'drawContours'

Contours will be drawn in different colors depending on some condition, so I need to be able to draw them independently.
What is producing this undesired effect?

Edit
Answering the comment, using converting to rbga with the following code
im = cv2.imread('image2.jpg')
im = cv2.cvtColor(im, cv2.COLOR_BGR2BGRA)
im_copy = im.copy()

for j,cont in enumerate(contours):
    im_copy = cv2.drawContours(im_copy, [cont], -1, (0, 0, 255,128), -1)
    im = cv2.drawContours(im, [cont], -1, (0, 0, 255, 255), 0)

Results in the following image:

A: Here is one way to do that in Python/OpenCV. To demonstrate, I will draw a partially transparent red contour on the largest regions. I do this by drawing once in full red on the input and then blending with the original input. I see no way to actually draw partially transparent contours directly.
Input:

import cv2
import numpy as np

# read image
img = cv2.imread('scan.png')
hh, ww = img.shape[:2]

# convert to gray
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

# threshold
thresh = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY+cv2.THRESH_OTSU)[1]

# get largest contour
contours = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
contours = contours[0] if len(contours) == 2 else contours[1]
big_contour = max(contours, key=cv2.contourArea)

# draw red filled contour on image background
back = img.copy()
cv2.drawContours(back, [big_contour], 0, (0,0,255), -1)

# blend with original image
alpha = 0.25
result = cv2.addWeighted(img, 1-alpha, back, alpha, 0)

# write results
cv2.imwrite('scan_transparent_contour.png', result)

# show results
cv2.imshow("img", img)
cv2.imshow("thresh", thresh)
cv2.imshow("result", result)
cv2.waitKey(0)

Results:

A: The issue was caused by addWeight(), as it was called once per contour. This caused some contours to be weighted more than one with the original image, so some regions appeared to be more transparet. I solved the issue in the following way:
im = cv2.imread('image1.jpg')
im_copy = im.copy()

alpha = 0.5
for cont in contours:
    if cv2.contourArea(cont) <= 1:
        im_copy = cv2.drawContours(im_copy, [cont], -1, (0, 0, 255), -1)
    else:
        im_copy = cv2.drawContours(im_copy, [cont], -1, (51, 197, 255), -1)
filled = cv2.addWeighted(im, alpha, im_copy, 1-alpha, 0)
for cont in contours:
    if cv2.contourArea(cont) <= 1:
        result = cv2.drawContours(filled, [cont], -1, (0, 0, 255), 0)
    else:
        result = cv2.drawContours(filled, [cont], -1, (51, 197, 255), 0)

cv2.imwrite('result.bmp', result)

I have been meaning to post this information up for the last 2 weeks. Recently I came across an interesting article from the SC Magazine regarding a new EU Law that will apply to the 27 counties within the EU. Viviane Reding, vice-president of the European Commission in charge of justice, fundamental rights and citizenship mentioned that companies will need to report breaches within 24hrs.
The article goes on to explain the need and role of a data protection officer. For more details please see the following link.

GEMINI MAN (2019) – My rating: 8/10
Gemini Man is an action thriller directed by Ang Lee and written by David Benioff, Billy Ray, and Darren Lemke. Gemini Man follows a hitman who is targeted by a younger clone of himself while on the run from the government. I waited with bated breath for this movie, it didn't let me down.
**** SOME SPOILERS ****
Henry Brogan /Jackson Brogan (codenamed "Junior"), (Will Smith), is a government-paid assassin with the Defense Intelligence Agency (DIA) and regarded as the best killer of his generation. Gemini Man opens with Henry, who has eyes on an anonymous terrorist aboard a bullet train that he has been commissioned to assassinate. Once in position, Henry's spotter alerts him of a young girl approaching the target, causing Henry to delay his shot until the last second. He shoots the man in the neck but was aiming for his head. Disillusioned by his aging skills, Henry retires from government service. While adjusting to retirement, Henry meets boat rental manager Dani Zakarweskiand (Mary Elizabeth Winstead) and reconnects with an old friend, Jack Willis (Douglas Hodge), who reveals that an informant named Yuri Kovacs (Ilia Volok) told him that the terrorist Henry killed was an innocent man. Demanding proof, Henry has Jack arrange a meeting with Yuri. In retaliation for Henry knowing their deception, agency director, Janet Lassiter (Linda Emond) plans to kill Henry. Clay Varris (Clive Owen), head of a top-secret black ops unit codenamed "GEMINI", request permission to do the job of getting rid of Henry but is denied.
Meanwhile, realizing Dani is a fellow agent sent to monitor him, Henry befriends her. After his home is broken into by government agents, Henry calls his spotter, who is killed along with Jack and his mistress. Henry warns Dani about the attack. Together they manage to kill the assassins sent after them, learning the agency wants them both dead. Escaping to Colombia, Henry and Dani go to the home of Henry's former colleague and friend, Baron (Benedict Wong) and plan to meet with Yuri for further options. Meanwhile, Clay gets his chance to dispatch his top assassin to kill Henry. While they are fighting, Henry realizes the assassin bears an uncanny resemblance to himself as a young man, with a similar skill set.
Gemini Man turned out to be a pretty good movie despite Will Smith's rather large ego. It's probably no coincidence that Will's character is considered the best in his particular field and because he's the best, only the best (a clone) could be considered for the job of assassinating "his best self". Fast-forwarding to the special effects, I think they were brilliant. In the old days when one actor played two people that looked exactly alike, their faces couldn't be shown together at the same time. Oh, how times have changed, in my opinion, the special effects were fantastic. The ending was a little cheesy but a nice idea. So how does a younger you kill an older you, after all, one of you knows every move the other is going to make. You'll just have to see this one to get all the answers. I recommend Gemini to all. It was fun and enjoyable, as I was thoroughly entertained. The film received generally negative reviews from critics, who complimented the performances but lamented the script and plot. The de-aging of Smith and the high frame-rate of 120 FPS drew a mixed response, with some critics praising them as technical achievements, while others felt they were unconvincing. Gemini Man has earned $119.2 million and was produced on an estimated budget of $138 million. Check It Out!

Recalling the brilliants of the Irish folk band The Clancy Brothers and Tommy Maken on the anniversary of the great Tom Clancy's death.
On November 7, 1990, the world lost Tom Clancy to stomach cancer, aged 66. Clancy left behind a wife, son, and five daughters, the youngest of whom was just two years old. The traditional music world was shaken by the loss of one of the Clancy siblings, who strode to fame Aran-sweater clad during the 1960s, alongside their friend Tommy Macken.
In tribute to Tom and to his brothers Paddy (died 1998, aged 76), Bobby (died 2001, aged 76) and Liam (died 2009, aged 74) we look back on the magic of the Clancy Brothers and their influence on music in America with this article republished courtesy of our sister publication, Irish America magazine.
As Liam Clancy remembers it, being asked to perform on "The Ed Sullivan Show" did not seem like a big deal.
"We just did not understand the significance," he told Irish America in a recent interview, during a publicity tour to promote a brilliant re-release of The Clancy Brothers and Tommy Makem performing live at New York City's Carnegie Hall in 1963.
Two years before that historic performance, as Clancy recalls, they were a group of slightly shady characters best known in that bohemian redoubt, Greenwich Village.
That all changed in March of 1961. The Clancys and Makem had already moved uptown to the Blue Angel on East 55th Street, a more respectable establishment frequented by TV talent scouts.
Sure enough, the Irish musicians impressed one of Ed Sullivan's scouts. The quartet later showed up at the Sullivan show studio for a Sunday rehearsal, only to be told that the evening's scheduled headliner, Pearl Bailey, had bowed out.
Could the Irish men perhaps substitute?
That night, 80 million Americans from Boston to L.A. heard the revolutionary sounds of The Clancy Brothers and Tommy Makem – the performance lasted a record-breaking 16 minutes.
"It was like getting a blessing from the Pope," recalled Liam with a laugh. Two years later came the historic concert at Carnegie Hall, where they cracked jokes about the new Irish Catholic president and earned loud applause simply by mentioning the IRA.
Clearly, something momentous had changed in Irish America. With their Aran sweaters, tin whistles and banjos, The Clancy Brothers and Tommy Makem might seem to be the quintessential Irish trad artists. But they were, in many ways, a radical departure, who then went on to change the Irish-American culture. How did they arrive at their unique musical sound? Why did some Irish-Americans consider them threatening? And how did they fit into an extraordinary moment in musical history, crossing paths with the likes of Bob Dylan?
The Clancy brothers – Paddy, Tom, Bobby, and Liam – were born into a musical family of nine children in Carrick-on-Suir, County Tipperary. Paddy and Tom served in Britain's Royal Air Force during World War II before immigrating to Toronto, Canada. After crossing the border and living in Cleveland for a spell, the duo moved to New York City, where they planned to work as actors. They had some success on the stage and screen but also felt the need to raise a little money. So they turned to an art form that came so naturally to them: music. Particularly memorable were some of their "midnight special" performances in the early 1950s at the Cherry Lane Theatre, where they were joined by their brother Bobby, who had also served in the RAF and traveled widely in Europe before ending up in New York.
As luck (or fate) would have it, New York in the mid-1950s was turning into a breeding ground for a new kind of folk movement.
It was in the mid-1950s that Liam, the youngest brother, joined Tom and Paddy in New York when Bobby returned home to Ireland to take over his father's insurance business. Liam too wanted to act, but he had also spent time performing, as well as studying and collecting the traditional music of Ireland. During his travels, Liam had become familiar with a particularly talented musician from Armagh — Tommy Makem. Many members of the Makem family had made their way to the U.S., to work in the textile mills of Dover, NH. Tommy did the same. He was injured on the job, however, and so joined the three Clancy brothers in New York.
When it was time to record their first album, "The Rising of the Moon," in the Bronx apartment of a young folklorist with the fine Irish name of Kenny Goldstein, they turned to a reliable formula: songs about drinking and Irish rebels. But it was clear from the beginning they were also breaking from the past.
Not only did the quartet avoid sentimental ballads, they also infused traditional Irish songs of rebellion and revelry with strands of fast-paced American folk, the improvisational feel of jazz and even the banter of cutting-edge beat poets and comedians.
The result was something familiar, yet very different. As the 1960s dawned, the group had a following, but nothing like mainstream success.
Maybe it was the unique style of The Clancy Brothers and Tommy Makem. Maybe, with one of their own in the White House, Irish-Americans were ready for a new kind of Irish music.
Or maybe it was the sweaters.
As legend has it, the Clancys' mother Johanna sent over four, thick, white Aran sweaters so the boys could stave off New York's winter chill. Now, Makem and the Clancys may not have been willing to play the stage Irish card, but their manager, Marty Erlichman, knew that if this act was going to hit the big time, they would have to appeal to some degree to Irish-American traditionalists.
Either way, when the quartet hit the stage on "The Ed Sullivan Show," they became at least as well known for their sweaters as for their tunes. But on the recently released recording, "The Clancy Brothers and Tommy Makem In Person at Carnegie Hall: The Complete 1963 Concert," something more than fashion or even music shines through. This recording captures the boys at the top of their game, but it also captures a unique moment in American history.
Between tunes, Makem gleefully cracks jokes about JFK – "big bad John in the White House" – as well as the American establishment.
"Hail Mary, full of grace – the Masons are in second place!" Makem cracks. Then there is the hilarious tune, "Mr. Moses Ri – Tooral – I Ay," about a Jewish-Irish merchant who is arrested for posting a sign with his name written in Hebrew – which is swiftly mistaken for Irish Gaelic by an ambitious British police officer.
"The song was written not so much to show the love between the Irish and the Jews so much as to show the stupidity of the British," Makem cracks.
Finally, introducing the rebel ballad, "The Patriot Game," a mention of the Irish Republican Army – which, in 1963, had not yet earned the mythic status it later would when the Troubles heated up in the late 1960s – earns lusty applause. Loud applause for a guerilla army defined as terroristic by the British? This is not exactly what you'd expect at Carnegie Hall. But this is the new world the Clancy Brothers and Tommy Makem helped create.
Following Ed Sullivan and Carnegie Hall, it might seem as if The Clancys and Tommy Makem were suddenly famous. They even performed for JFK himself in 1963. But they were overnight sensations well over a decade in the making.
When rock 'n' roll eclipsed folk music in the late 1960s, the Clancys often went their separate ways. After a year's notice, Tommy Makem left the group in 1969 to pursue a solo career. Bobby Clancy came back to fill his spot for a while and the four Clancy Brothers, sometimes with the addition of the two Furey Brothers, performed together on-and-off for the next couple of years. Tom found a lucrative career acting on TV, and Paddy devoted more time to his farm back in Ireland.
In 1975 Liam and Tommy Makem reunited to form Makem and Clancy, performing in numerous concerts and recording several albums as a duo, until 1988. The other three brothers united with their sister's son Robbie O'Connell and went on to perform as The Clancy Brothers and Robbie O'Connell, spending several months in America each year.
In 1984, Makem & Clancy's manager, Maurice Cassidy, brought the original foursome together for a concert at Avery Fisher Hall in New York City – the show sold out all 3,000 seats in a week.
In May of 1990, Tom Clancy died at the age of 66; his brother Paddy died eight years later. Tommy Makem passed away in 2007.
But the Clancy Brothers' legacy is alive and well in the 21st century. Liam not only has the Carnegie Hall show to promote. He also has a new documentary film, "The Life and Times of Liam Clancy," as well as a new album, "The Wheels of Life." He continues to tour the world, with no thoughts of retiring. "You can't retire from living," says the 74-year-old with a laugh.
* Liam Clancy died, aged 74, on December 4, 2009, in a hospital in Cork Ireland.
