Il Widna, Malta
The only sound mirror outside England – unless anyone knows better – is on the Mediterranean island of Malta. It is known locally as "il widna", Maltese for "the ear".
The design is the same as the 200 foot mirror at Denge, although the Maltese mirror appears to be in better condition. It retains its painted camouflage pattern, which blends into the colours of the landscape quite effectively.
The site is now used as an earth station for telecommunications company GO (formerly Maltacom), so there is no access to the mirror, though visitors can get quite close and peer through the barbed wire fence.
The construction of early warning sound mirrors was proposed in the early 1930s to help protect the key imperial locations of Gibraltar, Malta and Singapore. Four sites were identified in Gibraltar, but there were concerns about interfere produced by noises from the local population, the wind and the sea. A system of five to eight mirrors was suggested for Singapore, but it was thought that there would be problems with noises from local animal and insect life.
The surveys undertaken in Malta during 1933 were more productive, and five suitable sites were identified around the coast. The ideal site should be sheltered from noise behind and to the sides of the mirror, and 'under no circumstances should the mirror have a view if the breaking sea', said Dr Tucker, who undertook extensive research into sound-based direction finding.
The five proposed sites were given letters
- Ta Karach
- Ta Zura
- Tal Merhla
Priority was given to A and B, which were either side of Valletta and would help to protect the Grand Harbour. The first mirror was to be at Maghtab, on a site a mile or so inland with hills behind. It faces out to sea at a bearing or 20 degrees, towards Sicily around 60 miles away.
Construction was underway in the autumn of 1934, with the work completed during the summer of 1935. The design is a direct copy of the 200 foot mirror at Denge, near Dungeness in Kent. Minor differences include small projecting buttresses at the foot of the mirror face, which were found to harm its performance.
The electrical equipment was installed in the first weeks of September 1935, and testing was undertaken on 23 September. Training of the operating staff began the next day. The total cost of the development of the first mirror on Malta was put at £4500.
Trials using a Supermarine Scapa flying boat found that the range of the mirror was 21 to 37 miles, with an average of 25 miles, and a bearing error of ±2½ degrees. In contrast, the range of the unaided human ear was put at 5 miles. It was estimated that the mirror would provide a six minute warning of an enemy aircraft approaching Malta at 250 mph.
Unfortunately not all the test were successful, perhaps one of the more embarrassing failures being on 5 February 1936 during a visit by Sir Cyril John Deverell, Chief of the Imperial General Staff. No further mirrors were built on Malta, and the Maghtab mirror was reported to be out of use by 5 May 1937.
In May 2008 I had the chance to make a brief visit visit to Malta, so took the opportunity to track down the mirror.

From Valletta bus station I caught bus number 55 to the terminus at Gharghur, which takes about 35 minutes. As I got off a little old lady came over to ask me where I was going, as she was slightly concerned that I might be lost. I mentioned the "widna", and she knew straight away what it was, and kindly took me to see it. A local chap mending a car also knew the way, and I'd suggest the best way of finding the mirror is simply to ask someone (widna is pronounced as it would be English).
A few minutes walk from the town centre, we turned down a small road along the side of a ravine, through the Victoria Lines, and from the brow of the hill had a view across the fields below, with the earth station in the middle (and a humongous landfill site in the distance).
The white satellite dish makes the mirror pretty easy to spot, though binoculars are helpful for a good view. The track runs down to the bottom of the hill, passing a small cave containing a shrine. From the bottom of the hill I found my way to the mirror by trial and error.
Unfortunately my trip them went horribly wrong, when I thought I was on a different main road to the one I was actually on, and I had a long walk along a busy road until I found a bus stop at Salina Bay. A better move would have been to return to Ghargur, or head across to the coastal road and catch a bus to Sliema from there.
Malta has pretty obvious merits as a holiday destination, and absolutely bristles with things of interest to history enthusiasts, and especially fortification anoraks. I can thoroughly recommend the guided tours of the steam-operated gun at Fort Rinella, which somehow managed to entertain a group of women who were simply ticking off the attractions, a chap with technical questions about the control system, and me wanting to know about sound mirrors.

Executive Summary
Analyzing 0-1 matrices is one of the main themes in data mining. Techniques such as clustering or mixture modelling, matrix decomposition techniques such as PCA, ICA, and NMR, and Bayesian all aim to give an answer to the informal question: "Where does the matrix come from?" These approaches aim at describing a probabilistic generative model that describes the observed matrix well. This paper considers yet another way of answering the question "Where does a 0{1 matrix M come from?" In the model, the matrix M of size n? m is considered to arise from initiators, certain few entries that are initially 1.

text: Integrable turbulence arises while noisy initial data are launched into a system described by an integrable wave equation. Over recent years, the study of the complex dynamics and non-Gaussian statistics in integrable turbulence has become a growing and fundamental field of research. In this chapter, we show how recent theoretical results obtained in the semi-classical (zero-dispersion) limit of the focusing one dimensional nonlinear Schrödinger equation (NLSE) can be related to the phenomenon of integrable turbulence. One of the outcomes of the semi-classical NLSE analysis is an asymptotic description of the evolution in the framework of finite-gap theory, also known as periodic inverse scattering transform (IST), and we show how this periodic IST can be used to characterize integrable turbulence. Finally, we review optical fiber experiments devoted to the study of (near) integrable turbulence. In particular, we show how fast measurement techniques (time lens, time microscope, optical sampling) now allow the detailed study of the complex and fast dynamics arising from the propagation of partially coherent waves in optical fibers. These experiments provide physical confirmation of some fundamental predictions of the semi-classical theory.

From NIV, Luke 17:
One common interpretation here is that the "little ones" refers to children, however, this is not obvious in the context, and there are many other possibilities, including sinners, doubters, everyone, etc. Indeed, this may also hinge on what "to stumble" means here: whether it is to doubt their faith versus tempt to sin, or something else.
Is there a common agreement on who the "little ones" are here?

Matthew 18 also cites Jesus' words regarding little ones, and does so more frequently:
In this context, Jesus specifically identifies a child and speaks of children, then refers to children as "these little ones". So, interpreting Scripture in light of Scripture, it is pretty conclusive that "little ones" refers to children.

It sounds to me like "one such child" means "whomever humbles himself like this child" – kurosch Aug 28 '12 at 21:15
Jesus starts to speak about the children after the proud disciples start to debate about who will be the greatest, and also forbid others from casting out demons in Christ's name just because they were not approved by the Apostles. The literal little children represents little disciples that were not considered great. – Mike Aug 29 '12 at 5:43

If you look at Wesley's Explanatory Notes,

However I would be interested in seeing what Hermeneutics says about this one too. I suspect that the original words can be translated a little differently - but similarly / same meaning.

(+1) Of course he refers to weak believers the children are just symbols of his teaching as is almost everything in the gospels. The whole context of the narratives show his concern for the weak who like bruised reeds he would not break, or smoldering wicks he would not snuff. Those who keep the faith from baby Christians from growing are greatly warned. These are false prophets, etc. – Mike Aug 29 '12 at 5:37

Haydock's commentary quotes venerable (is he not a saint yet?) Bede as pointing out the similarity in words used in the parable of the lost sheep
In the same way your Father in heaven is not willing that any of these little ones should perish. > Matthew 18:14 NIV
Here, little ones means sheep, which usually means whoever follows the shepherd. The shepherd being Jesus. The key component of sheep-hood is obedience and humility (at least the humility of knowing you're a sheep)
But, more to your question, there's nothing wrong with having lots and lots of explanations of the Bible. I think that Jesus is talking about real children here because He taught with examples all the time ("see that poor woman over there, she gave more than you bums"). So, the literal interpretation is little ones = little people and that should do a little to give any pedophile priest a bit of pause while reading that Gospel.
The metaphorical sense is that little one means freshly minted or potential Christ follower (which would include children) since hindering these folks on their spiritual journey could have gave consequences grave punishement is afforded the purpotrators.
The moral sense of "little ones" might be that little ones are those that it is incumbent on all the teachers of the faith to pass on to their students authentic teaching that will not confuse them or encumber their spiritual growth.
The eternal sense tells us of the punishement due to those who were given much but stink at passing it on. Which is why I approach each year of Catechism Class with fear and trembling.

New research shows that dolphins can stay awake for at least 15 days in a row without experiencing fatigue, or other negative side effects.
To put this in perspective, human research subjects have been able to stay awake for only eight to 10 days, and all experienced progressive deterioration in concentration, motivation, perception and other mental processes as the period of sleep deprivation increased.
Dolphins can stay awake for this long because they sleep with only half of their brain at a time. This process, called unihemispheric sleep, was thought to have evolved as a way to allow dolphins to continue breathing at the surface while resting.
Brian Branstetter from the National Marine Mammal Foundation and colleagues studied two bottlenose dolphins (Tursiops truncatus), one male and one female, and found that they could use echolocation with "near-perfect accuracy" for up to 15 days. Both dolphins showed no signs of fatigue for five days, and the female continued other tasks for 10 additional days.
"These majestic beasts are true unwavering sentinels of the sea. The demands of ocean life on air breathing dolphins have led to incredible capabilities, one of which is the ability to continuously, perhaps indefinitely, maintain vigilant behavior through echolocation" said Branstetter.
The research was published in the journal PLoS ONE on October 17: Dolphins Can Maintain Vigilant Behavior through Echolocation for 15 Days without Interruption or Cognitive Impairment.

Thermodynamic - water/ice piston help!
An inventor proposes to make a heat engine using water/ice as the working substance inside a cylindrical piston and taking advantage of the fact that water expands as it freezes and can therefore lift a piston supporting some mass m. The engine process consists of four steps as shown in the schematic below.
(i) Load: The weight to be lifted is placed on top of a piston over a cylinder of water held at a temperature of 1oC. The piston sits at height hw.
(ii) Lift: The system is then placed in thermal contact with a low temperature reservoir at −1oC until the water freezes into ice, lifting the weight to a height hi.
(iii) Unload: The weight is then removed at height hi while the ice remains frozen.
(iv) Reset: The ice is melted by putting it back in contact with the high-temperature reservoir at 1oC, returning the piston hw. Another mass is added to the piston and the cycle is ready to be repeated.
The inventor is pleased with this device because it can seemingly perform an unlimited amount of work (by lifting an unlimited mass m) while absorbing only a finite amount of heat each cycle.
Assuming that the piston has a cross-sectional area of 10 cm2 and contains 50 cm3 of liquid H2O (i.e. hw = 5 cm), calculate:
(i) The work done by the piston in raising a mass of 10 g.
(ii) The mass required to stop the engine working (i.e., reduce the freezing point of the water to −1oC).

the new wizard pretending to be a new user, and I ran into trouble trying to paste code.
This is the help for adding code: enter image description here
The help gives the impression that the user has to hit the space bar four times for every line of code.
There should be a code button like the usual template, or the wizard should at least mention the Ctrlk shortcut for formatting code.
Since formatting is something that new users often mess up on, the wizard should put in every effort to turn out well-formatted posts. This has to begin with a comprehensive guide on how to format properly. This is one way that the wizard could really help. In fact, it is the obvious way to teach new users how to handle code in posts, but the wizard is misleading instead of helpful.
: Please add the necessary material to help new users format their code.
I think the matched title search needs to work better.
Normally we put in the title first, then the question then the tags, so it's as good as it gets. Now we are putting in tags then title. The title search should reflect the tags. For instance I asked about Unity, and I had the Unity3d tag, but the first 5 titles had nothing to do with unity. Similar problems, but in other platforms making them completely unrelated. I got bored of looking at titles before I reached anything unity related.
Now that we have the tags, we should show questions with the same tags first as suggestions for previously asked
I know that technically, this is "ok". The tag is not a tag but included as a part of the sentence. Meh. But please do not encourage newbies to repeat information. Their title should state what the problem is. I see too many titles that are basically just the tags with some auxiliary verbs sprinkled in. If it's tagged already, I don't need that repeated in the title.
And while we are at it: I think questions should ask a question, so even if you don't want to implement that in the wizard, it would be nice if we could at least lead by example and have our example headlines ask a question. Including the proper punctuation.
How about using placeholders in the form?
Question guide screen alternative
This would allow the person to read all the examples immediately before writing (since some might not read/notice the changing examples in the sidebar).
I just used simple unicode characters for the icons in the placeholders:
Examples:
✔ "Include lines 12-23 of /file.php"
❌ "Don't paste entire /file.php"
✔ "Indent four spaces to format your code"
❌ "Don't paste line 23 only"
I don't think the following wording is clear enough, especially to someone new to asking technical questions:
Describe expected and actual results.
It would be better to be more explicit, along these lines:
What result were you expecting to see? What actually happened instead?
Or more in line with the existing wording:
Describe the result you were expecting, and then describe the result that actually happened.
It is great to get the opinion of veteran users on this much needed new tool...
But is there a "next stage" of testing:
Getting new users (aka: zero rep) users to try it, without instruction
... and see how they do?
Unless there's major opposition to this idea, when I'm back on in a few hours, going through new VBA/Excel questions as regularly do, when I come across poorly written questions from newbies (Rep 0-5) I will ask if the user is willing to resubmit their question with this tool, with no input from me, then the user and I will look at the two questions, together decide which is better, and promptly delete the other one, and I will make notes on the process and report back here.
I'll only do this on 2 or 3 questions to start, but that's the true test of this wizard, right? VBA is a slow enough category on a Friday night that any confusion over the duplicates will be minimal.

 We're actually doing both. We've been doing user testing with users outside of the meta community (even before we posted here) and we're planning to continue doing so as we get closer to the experiment stage. Stay tuned! – Jon Chan Jun 22 '18 at 21:51
 - _USER_ good to hear! Will this testing include "brand new" (zero rep) users? Seems to me that's where the real issues will come to light since they are the most likely to "break" the wizard, or to misunderstand the process. The wizard is a great idea and I look forward to the full launch! – ashleedawg Jun 23 '18 at 1:34

 _USER_ I am curious if it will be obvious which questions were created by the wizard, and whether the user will be able to re-enter the wizard after the question is posted. – ashleedawg Jun 23 '18 at 1:36

 I haven't tried working my way through the entire template. I didn't know if there was a point of no return I might accidently skip over. If the system could recognise if this is the first time you have used the wizard and before/after submit give you short scoring questionnaire e.g. ease of use 1-3, were the question tips easy to understand, and a final suggested improvements free text box...... might this be a way to gather more feedback? The user could opt out of completing...... I guess could be detrimental if new users viewed it as an additional hurdle. – QHarr Jun 23 '18 at 4:22
 - _USER_ actually on that thought, combined with my previous comment -- it would be nice if we could identify from SEDE which questions were produced by the wizard, because we could easily compare questions scores and results for questions with/without the wizard – ashleedawg Jun 23 '18 at 22:34

Accuracy of landmark scalp blocks performed during asleep-awake-asleep awake craniotomy: a retrospective study
To the Editor,
Awake craniotomy (AC) is often performed in patients with brain tumors that are present in regions linked to language processing to minimize any damage to language functioning [1]. During ACs, scalp blocks affecting the supraorbital nerve, supratrochlear nerve, greater and lesser occipital nerve, auriculotemporal nerve, and zygomaticotemporal branch nerve enable safe surgical procedure during the awake phase of ACs [1, 2]. If the scalp block is not effective, it becomes difficult to perform any awake tasks with the cooperation of the patient, as performance is hindered due to headache.
Scalp blocks in ACs are often performed under general anesthesia; however, at our hospital, we perform scalp blocks before the patient is anesthetized to achieve less headache during the awake phase [3]. If the block effect is insufficient as no sensation reduction is demonstrated by the cold test after blocking, an additional dosage of local anesthetic can be administered. To date, no study has considered the accuracy of scalp blocks performed by landmark methods. In this study, we retrospectively investigated the accuracy of scalp blocks performed using the landmark method in ACs.
This study was approved by the Ethics Committee of Nagoya University (Approval number: 2020-0108). We investigated retrospective cases of ACs (n = 103) performed at Nagoya University Hospital from January 1, 2016, to May 30, 2020. We performed all scalp blocks bilaterally by landmark methods as described previously with 0.375% ropivacaine [1, 3]: 1.5–2 mL for supraorbital/supratrochlear nerves, 2–2.5 mL for greater/lesser occipital nerves, 3–5 mL for auriculotemporal nerve, and 3–5 mL for zygomaticotemporal branch nerve (total number, 206). After all of the scalp blocks were performed, we assessed the number of block failures on each side by using the cold test before induction. We compared the number of block failures using Cochran's Q test. The statistical analyses were performed with EZR (Saitama Medical Center, Jichi Medical University [4]). All data were analyzed using Cochran's Q test and McNemar test with the post hoc Bonferroni test. P < 0.05 was considered statistically significant.
The rates of failure in the scalp blocks were as follows: supraorbital and supratrochlear nerve (n = 5, failure rate 2.4%), greater and lesser occipital nerve (n = 15, 7.2%), auriculotemporal nerve (n = 23, 11.1%), and zygomaticotemporal branch (n = 34, 16.6%).
Among these blocks, the zygomaticotemporal nerve block failure rate was significantly higher than in other nerves (P < 0.001, at the Cochran's Q test, versus supraorbital and supratrochlear nerve (P < 0.001), greater and lesser occipital nerve (P < 0.001), auriculotemporal nerve (P = 0.015)).
This study revealed the failure rate for zygomaticotemporal nerve blocks was higher than that of the other nerve blocks. The zygomaticotemporal nerve is distributed deep below the surface of the skin and can have anomalies [5, 6]; therefore, it can be difficult to anesthetize using the anatomical landmark method. Patients often suffer headaches during AC, and as the zygomaticotemporal nerve is a nerve responsible for the sensation in the surrounding temple [6], it may be the cause of temporal pain during an AC.
To improve the success rate of the zygomaticotemporal nerve, further studies assessing different blocking techniques, such as using ultrasounds, are required in the future.

The Vacuum Infusion Process (VIP) is a technique that uses vacuum pressure to drive resin into a laminate. Materials are laid dry into the mould and the vacuum is applied before resin is introduced. Once a complete vacuum is achieved, resin is literally sucked into the laminate via carefully placed tubing. This process is aided by an assortment of supplies and materials.
- Basfiber® Fabrics.
- Vacuum Pump.
- Sealing Tape.
|Vacuum infusion Application Process|
|Basalt Fiber Tech Vacuum infusion Application Process©2015 - Designed by Lucas Sant'Anna|
- A Mould is placed over a Plastic Layers, using a sealing tape you cover the edges. In the next step Basfiber® Fabrics will be applied over the mould. The amount of layers of fabrics depends on final product specifications.
- Basfiber® Fabrics layer is placed over the mould. A second plastic layer is applied. Pressurizing the tape on the edges of the plastic, the mould should be completely sealed.
- Vacuum Pump is attached to the plastic, a resin is also connected. Both hoses must be connected to the plastic providing sealed bag strong enough to pull the resin until air is removed.
- Resin Impregnation occurs when all the air is removed from the plastic bag forming a vacuum. When all bubbles are removes and the pump reaches the maximum pressure, the resin input is closed and the resin excess is removed from the mould.
- Remove from Plastic and Trim edges and make sure there is no resin bridging the line between the mould and the part. Sand this edge where necessary. Continue separation by pulling and flexing.
- The Final Product is now painted and completed with accessories. The source mould can be used again, this process is very useful to recreate parts using them as original mould substituting the original then by a lighter resin infused Basfiber® composite.
Benefits of Vacuum Infusion
Vacuum infusion provides a number of improvements over traditionally vacuum bagged parts.
These benefits include:
- Better fiber-to-resin ratio.
- Less wasted resin.
- Very consistent resin usage.
- Unlimited set-up time.
VIP offers a better fiber-to-resin ratio than vacuum bagging. A typical hand lay-up usually results in excess of 100% fabric weight by resin. Resin alone is very brittle, so any excess will actually weaken the part. Vacuum bagging can reduce this number significantly; however, it is still not ideal and can lead to additional problems.
While vacuum bagging certainly improves on the hand lay-up, there is still a hand lay-up involved. Because of this, the laminate will always begin in an over-saturated state. Vacuum pressure will remove much of the excess resin, but the amount removed still depends on a variety of variables including reinforcement, resin, time factors, and others.
Vacuum infusion takes a different approach, in that a vacuum is drawn while the materials are still dry. From that point, resin is infused using vacuum pressure. Rather than starting with excess and drawing resin out, VIP starts with none and pushes resin in. Ideally, any excess resin that is introduced will eventually be sucked out into the vacuum line. As a result, only the minimum amount of resin is introduced. This lowers weight, increases strength, and maximizes the properties of fiber and resin. Parts constructed using VIP can approach PrePreg levels of resin content.
Due to the nature of VIP, resin usage becomes very predictable. While a standard lay-up varies in resin content due to the human variable, VIP is remarkably consistent. Even when creating a large product, resin usage will be predictably similar upon repeated attempts. This results in less wasted resin, and more importantly, less wasted money.
Vacuum infusion provides another valuable benefit: time. A frequent problem that can arise in vacuum bagging is the time factor. Many resins have a pot-life of about 30 minutes, though there are certainly some (such as our System 2000 Epoxy) that offer work times of up to 2 hours. Even so, that time limit is extremely critical in vacuum bagging applications. Large projects can easily approach the 2 hour mark, and even small, seemingly simple projects can quickly turn frantic when a pesky leak in the vacuum seal cannot be found. Also, depending on when the bag is applied, the amount of resin removed can vary from part to part.
Vacuum infusion, however, offers unlimited set-up time. Because the vacuum is applied while reinforcements are still dry, there is no resin clock to work against. After the bag is applied, leaks can be patiently sought out. If something is not sitting properly, simply release vacuum and readjust. No time constraints are introduced until it is decided that it is time to infuse the resin. Until that moment, changes can be made again and again.
Finally, vacuum infusion is a much cleaner process. There are no brushes or rollers, and therefore no splashing or spattering. No one will be required to hover over an open mould, saturating a laminate by hand, trying not to drip on himself. In addition, there are less resin fumes to contend with. Because the only fumes radiate from the resin reservoir, they are somewhat containable. VIP provides a cleaner, safer, and friendlier work environment, though it is still important to work in a well ventilated area and wear a respirator and other appropriate safety equipment.

What is your bartender's favorite cocktail? A Great question, and one usually asked towards the end of the night. It certainly wouldn't be the Manhattan or old fashioned, those are too common. It can't be the daiquiri, which is so misunderstood, or the mai tai, which is too complicated. The answer, seemingly more than any other drink, is the bitter Negroni.
The better question might be: why isn't the Negroni everybody's favorite drink? It's a dynamic sip, with fruitiness from the Campari, sweetness from the vermouth, and botanicals from the gin. It's bitter, making it both challenging to beginners and endlessly drinkable to fans. Perhaps most impressively, it's darn easy to make. Even the less-discerning dives are likely to have Campari, and the preparation requires neither mixing glass or shaker.
The most surprising thing about the Negroni is how few bartenders know how to make it. Outside the cocktail-wild halls of bigger cities, the drink still seems to be developing a name for itself. Luckily, at three even parts, the recipe can be explained in a single sentence. Consider it a public service. Perhaps one more bartender finds a favorite drink.

SAN MARCOS — Volunteers from across Texas will participate in the fourth annual statewide water sampling initiative to be held in conjunction with Earth Day 2003 on April 22.
Texas Watch, a volunteer environmental monitoring program supported by Southwest Texas State University, the Texas Commission on Environmental Quality, and the U.S. Environmental Protection Agency, is launching the effort.
Volunteer monitors across the state will sample surface and ground water to collect important environmental information. Those results will be coupled with professional water quality sampling efforts to realistically portray "A Day In the Life of Texas Waters."
More than 1,000 volunteer monitors are expected to participate, and approximately 200 sites will be surveyed in the sampling. Photos and monitoring results may be viewed online at the Texas Watch web site, _URL_.
Texas Watch facilitates environmental stewardship by empowering a statewide network of concerned volunteers, partners and institutions in a collaborative effort to promote a healthy and safe environment through environmental education, data collection and community action.
Jason Pinchback, who is in charge of volunteer coordination for Texas Watch, said, "Texas' budget deficit of an estimated $9.9 billion could impact funds designated to protect our natural resources. Reduced state funds, coupled with continuing increases in population growth and the resulting nonpoint source water pollution, intensifies the need for increased volunteer water quality monitoring efforts. The volunteers involved in Texas Watch, are taking the responsibility to help preserve a sustainable and viable future for our planet. This is an important effort, and we hope to gather some very significant data in the process."
Earth Day, a global holiday to honor the Earth and increase awareness of the need for its preservation, was first celebrated on April 22, 1970. The statewide sampling event and other Earth Day 2003 activities celebrate 33 years of environmental stewardship promoting a clean future for the planet.

object, define the connection string, and open the Connection object. However, I then define the command text and assign it to the ctContacts variable, but I do not create a Command object. If your commands don't require Parameter objects (which I describe later in the article) or special property settings, you often don't need to create a Command object. For instance, if you simply want to retrieve a list of contacts from the database and you don't need to pass any parameter values (such as a contact ID) into your SQL statement, you can simply define the command text and not bother creating a Command object.
After I define the command text, I create the Recordset object. When I open the object, I pass two arguments. The first argument is the command text (the ctContacts variable), and the second argument is the Connection object (the conSqlServer variable). After you open the Recordset object, you can access its properties and methods just as you saw in the previous examples.
You can also create a Recordset object without creating Connection or Command objects. Listing 6 shows an example of how this works. In this script, I first define the connection string and assign it to the csSqlServer variable. Next, I define the command text and assign it to the ctContacts variable. After this, I create the Recordset object and use the object's Open method, passing the two variables as arguments to the method—first the connection text and then the connection string. As you can see, this approach is even simpler than the previous approach, and it works well if you plan to include only a single recordset. For example, if you want to retrieve a list of contacts only once and you need to connect to the database only once, then you probably don't need to create a Connection object or Command object. However, if you have multiple recordsets maintaining multiple connections, you should first create the Connection and Command objects.
The Field Object
The examples I've shown you so far have all used the Recordset object's Save method to save the returned data to an.xml file. However, in all likelihood, you'll want to dig a lot deeper into the data than I've done. That's where the Field object comes in.
As you'll recall from Figure 1, the Recordset object includes the Fields collection. This collection is made up of one or more Field objects that each represent a field returned by the command text. For example, if your command text returns data from the FirstName, MiddleName, and LastName columns of the Person.Contact table in the AdventureWorks database, your Recordset object will include three Field objects, one for each of those columns.
Listing 7 provides an example of how you can use the Fields collection to access the Field objects. After I create the Recordset object, I create a FileSystemObject object and a text file to hold my data. I then use a Do Until statement to create a loop. I plan to loop through the result set and insert the data into the text file. The Do Until statement first uses the Recordset object's EOF property to specify when to end the loop. When the loop reaches the end of the result set, it will stop.
Within the loop, I concatenate two Field objects: FirstName and LastName. To retrieve a value for a field, I call the Fields collection (rsContacts.Fields) and specify the name of the first field (FirstName) in parentheses. I follow this with the Value property so I can retrieve the specific value. I do the same thing for the LastName field and concatenate the two values.
After the concatenation, I use the Recordset object's MoveNext method to retrieve the next row in the result set. As a result, for each row, the first and last name will be concatenated and written to the text file.
This, of course, is a simple example of how to access the Field object, but it does demonstrate the basic concepts behind using Field objects and gives you a better sense of the crucial role that the Recordset object plays in ADO. Now let's take a look at another important ADO object—Parameter.
The Parameter Object
The Parameter object is similar to the Field object in that it's part of a collection included in another object. In this case, the Command object contains the Parameters collection, which is made up of one or more Parameter objects. Each Parameter object contains a parameter that you can use for stored procedures and parameterized queries.
Parameters are particularly important when you want to modify data in your data source. Listing 8 shows an example of passing parameter values to a stored procedure that updates a SQL Server table. For the purpose of this example, I created the HumanResources.Vacation table in the AdventureWorks database. Along with the table, I created the UpdateVacationHours stored procedure to update an employee's vacation hours. I used the following T-SQL statements to create the table and the stored procedure:
SELECT e.EmployeeID, c.FirstName, c.MiddleName, c.LastName, e.VacationHours
 INTO HumanResources.Vacation
 FROM Person.Contact c
 INNER JOIN HumanResources.Employee e
 ON c.ContactID = e.ContactID
CREATE PROCEDURE UpdateVacationHours (_USER_ INT, _USER_ INT) AS
 UPDATE HumanResources.Vacation
 SET VacationHours = VacationHours - _USER_
 WHERE EmployeeID = _USER_
Returning to Listing 8, you can see that I first create and open a Connection object, and then I create a Command object. After I create the Command object (which I assign to the cmdVacation variable), I set several properties and create the necessary parameters. First, as you saw in earlier examples, I assign the Connection object to the ActiveConnection property. I then define the CommandText property, which in this case is the name of the stored procedure. Next I set the CommandType property to the adCmdStoredProc constant (which equals 4). As the name indicates, the command type is a stored procedure.
The next step is to add Parameter objects to the Parameters collection. To do this, I use the collection's Append method. The argument that I pass to this method is the Command object's CreateParameter method. The CreateParameter method takes two arguments: the name of the parameter and the adInteger constant (which equals 3). The constant specifies that the parameter should be an integer. For this example, the first parameter is _USER_ and the second is _USER_.
That's all you need to do to create the parameters. However, notice that I also assign initial values to them. To do this, I call the Parameters collection, specify the name of the parameter, and assign it a value of 1. This provides a default value for the parameters, and it allows me to easily test the code.
After I define the parameters, I can execute the command. However, because I'm updating records and not returning a result set, I don't create a Recordset object as I did in earlier examples. Instead, I use the Command object's Execute method (cmdVacation.Execute) to run the stored procedure. As arguments to the method, I first specify the RowsUpdated variable. This will hold the number of records updated when the stored procedure runs. The second argument, which is blank, can hold a Variant array of parameter values, an alternative method for passing parameters to a command. The third argument is the adExecuteNoRecords constant. Including this argument is important because, by default, the Execute method returns a Recordset object when it runs. However, because you don't need this object, you should specify this constant to avoid the additional overhead.
When you run the script, it will call the stored procedure and return the number of rows affected by the update. Not surprisingly, numerous approaches are available for modifying data. For example, you can define command text that uses an EXECUTE statement to call the stored procedure, then pass in the parameter values through variables. Or you can define command text that uses an UPDATE statement rather than calling a stored procedure. ADO also lets you use methods in the Recordset object to update field data, which can then be persisted to the database.
A Place to Start
Although the examples I provided barely skim the surface of ADO, they should provide you with a good foundation to begin working with ADO. Once you understand how to implement the basic components of ADO in your script, you can start digging deeper into each object and try out the various ways to access a data source and work with the data. Again, refer to the MSDN Web site as necessary for details about the objects' properties and methods. And when you're ready, start playing with other ADO objects and see what you can come up with.

Definition of streptomycete in English:
A bacterium that occurs chiefly in soil as aerobic saprophytes resembling molds, several of which are important sources of antibiotics.
- Streptomyces and related genera, order Actinomycetales; Gram-positive filaments forming chains of spores
- In nature, tetracycline is produced by streptomycetes, moldlike bacteria commonly found in soils.
- The number of genes encoding Nudix hydrolases varies widely, from zero in most Mycoplasma species to around 30 in streptomycetes.
- This applies not only for molecules with an antibiotic activity like in the case of streptomycetes but also for compounds that may play a role in cell processes like signaling and communication.

The popcorn, or trinity stitch as it is called in the United States, is also known as the bramble or blackberry stitch in England, and the spider stitch in Italy. No matter what name you give to this stitch, this slightly raised pattern adds texture to a piece. This particular pattern includes both knit and purl stitches and allows the piece to remain soft and flexible while increasing the visual appeal.
Knit this pattern for any number of stitches that is a multiple of four. Practice with some worsted weight yarn and a larger set of needles before beginning a project that requires you to use the popcorn stitch.
Purl the first row. This will be the right side of the piece. Second row: knit one, purl one, knit one into the next stitch, purl three together; repeat from. Purl the third row. Fourth row: purl three together, knit one, purl one, knit one into the next stitch; repeat from.
Begin your project once you are comfortable with the stitch. Ensure that your tension is even and the "bumps" are nearly identical in size.

Indonesia, biomass, renewable energy, agricultural residue, energy production
Indonesia has great potential of biomass sources from their agricultural residue, which can potentially be used for alternative energy generation. This preliminary research explores the most suitable technology for energy generation from agricultural residue and its challenge for application in Indonesia. The study showed that biomass utilization via the direct combustion process is recommended for energy generation. It is also reported that the pretreatment process of drying and washing, are required to increase the fuel quality and plant efficiency.

Hand Bearing Compasses
Plastimo Iris
The Plastimo Iris 50 is a hockey puck style hand bearing compass with good reviews from our customers.
What they do
A hand bearing compass is used to measure the magnetic direction of sighted objects relative to the user. Two key questions you ask yourself while on the water usually concern your heading and your position. A steering compass tells you where you are going but its smaller sibling, the hand bearing compass, holds the answer to where you are. Unlike a GPS receiver that does the same–perhaps quicker, more conveniently and more precisely–the hand bearing compass does not rely on electrical power or satellite reception. It is a good backup and a formidable instrument for racing sailors to see who is sailing faster on the same tack or gybe.
How they work
A hand bearing compass allows you to take bearings of distant objects, which you can then transfer to a paper chart to create plot lines. Taking bearings of at least two objects that are 45 or more degrees apart results in intersecting lines on the chart, giving a position fix. To improve accuracy, we recommend taking bearings of three different objects and several sightings of each one and taking an average of the readings.
Hand Bearing Compasses
Different styles
We offer several different hand bearing compasses, either in "hockey puck style" or with pistol grips. High-end binoculars also come with bearing compasses, and many boaters prefer a good set of binoculars over a hand bearing compass, because they're easy to use.
How to take a bearing
To use an arm's-length compass (usually with a pistol grip), put the lanyard around your neck to stabilize the unit. Hold the compass at eye level, then line up the V-notches in the sighting vanes on the top of the compass with the desired object; now check the bearing on the compass card. If this sounds like juggling while walking across the street, you feel the same way we do. It can be tough to keep compass and sights lined up and checking some small numbers all at the same time. Add to that the motion of a boat in a seaway and poor visibility and you face long odds of taking an accurate bearing.
Hand Bearing Compasses
A better choice is a hockey puck style compass with an infinity prism that is held up to your cheek, and lets you sight across the top of a small prism. When you are focusing on the object in the distance, the prism projects the bearing into your field of vision so you don't have to shift your eyes. Object and bearing are in focus at the same time, which is a tremendous asset for taking accurate bearings in rough conditions.
Operating a digital compass is very much like taking a snapshot. You use the unit's aiming system to take the sight, then press a button. The compass stores the bearing in electronic memory for future recall.
Avoiding a Collision
Hand Bearing Compasses
Take a bearing upon first sighting another approaching vessel, like a ship. Take a second bearing a few minutes later and repeat at regular intervals. If the approaching ship's bearing remains the same, you are at risk of a collision. It their bearing has changed, rotate so you are sighting along the original bearing. If you're now looking at the water in front of the ship, you'll pass ahead of it. Sighting behind the vessel means it will pass ahead of you.
What to look for
 - Compactness: We really like the models that are comfortable to wear around your neck on a lanyard and fit easily in a pocket, so you can keep them nearby.
 - Night Lighting: Like other navigation instruments, bearing compasses should have night-lights. Some use small battery-powered lamps. Others have glow-in-the-dark lighting which uses small quantities of photosensitive or radioactive gas. We like this type best because it is ready at a moment's notice, and never needs charging or new batteries.
 - Accuracy: A precisely graduated card and excellent damping are critical for obtaining accurate sights. On a moving boat, most people can get a bearing accurate to 2-3 degrees using a well-damped, infinity prism compass that is held near the cheek. In a seaway, pistol grip compasses that are held at arm's-length are probably accurate to about 10 degrees. Sources of error that affect the quality of your bearing include inaccurate aiming, violent motion, steel-rimmed glasses and bad visibility.


Take the 2-minute tour ×
Let$\:$ $T=\{\varphi \in \Pi_1: PA+Con(PA) \vdash \varphi\:\:and\:\: PA\nvdash \varphi \}$. $\:$By the facts presented here Are undecidable consequences of Con recursively enumerable? by Andreas Blass and Emil Jerabek, we know that:
$(1)$ $T$ is $\Pi_1$-hard.
However it seems we can also prove that
$(2)$ $Cn(PA+Con(PA)) = Cn(PA+T)$
Let $\varphi$ be such that $PA+Con(PA) \models \varphi$. Obviously $Con(PA) \in T$, therefore trivially $PA+T \models \varphi$.
In the other direction, let $\varphi$ be such that $PA+T \models \varphi$. Since this is a first-order theory, by completeness and compactness we can infer that in the proof of $\varphi$ from $PA+T$ we use finitely many formulae, namely: $\phi_1, \phi_2, \dots \phi_n$. All of them either belong to $PA$ or belong to $T$ or can be inferred from $PA+T$. In particular they are implied by $PA+Con(PA)$. If so, they can be used in the proof of $\varphi$ form $PA+Con(PA)$, so $PA+Con(PA) \models \varphi$.
But from the work of Jeroslow _URL_ (Corollary 4) we find out that:
$(3)$ $Cn(PA+\{\varphi \in \Pi_1: \mathbb{N} \models \varphi \})$ is not $\Delta_2$
Since $(1)$ and due to the fact that the set above (I mean: $\Pi_1 \cap Th(\mathbb{N})$) has got its own truth definition and is $\Pi_1$ we infer that it is reducible to $T$.
So it seems that $Cn(PA+T)$ should also be "hard" and "not learnable" (in the sense of not being $\Delta_2$ ).
However we also know that $Cn(PA+Con(PA))$ is $\Sigma_1$. Since $(2)$ however $Cn(PA+T)$ is the same set of formulae.
So my question is: did I make any mistake in the reasoning above and one of $(1)$, $(2)$, $(3)$ is false or it can be the case that when we close some "hard" set up logical consequence, we can get an "easier" set. If so, the question is: how come?
share|improve this question
I don't see any mistakes. A good chunk of the complexity of T comes from excluding certain sentences; specifically, those sentences provable in PA. But adding PA and then closing under consequence restores those sentences. That's why the complexity decreases. – Dan Turetsky Jun 5 '13 at 23:48
Thanks. You're right, but let's look at the theory I mentioned: PA+(Set of true Pi_1-sentences) which closed under consequence gives us nonlearnable theory. I don't "see", how - having a computable reduction of Set of true Pi_1-sentences to the set T- we obtain theories with different complexities? – mtg Jun 6 '13 at 0:15

The $\Pi_1$-hardness of $T$ comes from the clause $PA\not\vdash\varphi$. But when you consider $Cn(PA+T)$ its influence vanishes.
As $$T\subset Cn(PA+Con(PA))$$ we have $$Cn(PA+T)\subseteq Cn(PA+Cn(PA+Con(PA)))=Cn(PA+Con(PA)).$$ On the other hand $Con(PA)\in T$ therefore $Cn(PA+Con(PA))\subseteq Cn(PA+T)$.
Thus we have the equality $Cn(PA+T) = Cn(PA+Con(PA))$ indeed.
This also does not contradict Jeroslow's results as in $PA+\Pi_1(\mathbb{N})$ there are all $Con(X)$ (not just $Con(PA)$) and which is a sourse of complexity of this theory.
It is not very suprising that Cn operator can decrease the complexity of a set of sentences - you can always add a negation of a sentence of any given set to obtain an inconsistent theory i.e. primitive recursive. But it is a nice example how it can decrease it to something higher than just PR.

Why You Need Weighted Average for Calculating Total Portfolio Return
This is a very basic article explaining why unweighted arithmetic average is not suitable when portfolio is not equally weighted. See more about When to Use Arithmetic Average and When Not.
3 stock portfolio example
Let's say you have 1 million dollars and you want to invest it in stocks. You construct a fairly concentrated portfolio – you particularly like stock ABC. At the beginning of the year you have invested 1 million dollars in 3 stocks:
- Stock ABC: 80% of portfolio = USD 800,000
- Stock DEF: 10% of portfolio = USD 100,000
- Stock GHI: 10% of portfolio = USD 100,000
The important factor for illustrating the point of this article is that the positions have different weights in the portfolio: 80%, 10%, and 10%.
Performance of individual stocks
One year later, you are looking at your portfolio's performance. The 3 stocks performed like this:
- Stock ABC -20%
- Stock DEF +10%
- Stock GHI +40%
Arithmetic average of the stocks' returns
What is the arithmetic average? The sum of -20%, +10% and +40% equals +30%. Divided by 3, the arithmetic average of the stocks' returns in the last year is +10%. (See How to Calculate Arithmetic Average: The Very Basics).
Percentage return and P/L of total portfolio
How much money have you made?
- In stock ABC you have lost 20% of 800,000 = USD 160,000
- In stock DEF you have made 10% of 100,000 = USD 10,000
- In stock GHI you have made 40% of 100,000 = USD 40,000
The whole portfolio P/L is negative 160,000 plus 10,000 plus 40,000, which equals a loss of USD 110,000. On percentage basis, you have lost 11% of your initial investment.
Why is arithmetic average not working?
Though 2 of the 3 stocks have risen and arithmetic average of the 3 stocks' returns is +10%, your portfolio has lost money, as your biggest (and losing) position in stock ABC has outbalanced the two smaller positions. Had your portfolio been equally weighted (each stock 33.3%), its return would have been +10%. But you were unlucky to allocate more to ABC, the one stock that has lost in the end.
Weighted average is better for calculating total portfolio return
For calculating average return of a portfolio or basket of stocks, arithmetic average is only suitable when all stocks have equal weights in the portfolio, which is rarely the case. When the weights are different, you need to take it into account and use weighted average instead.

Attesting Russian Documents For The UAE
The attestation of Russian Documents can be quite a complicated process and varies depending on the type of document you wish to attest. The general process for all documents is detailed below.
How It Works
 - Send us your documents or have them collected by our specially allocated couriers.
 - We'll have them sent safely to Moscow, Russia, where four things will happen:
 1. The document will be sent to the Ministry of Justice where a stamp of authentication will be applied.
 2. Then, your document will be sent to the Ministry of Foreign Affairs, where another stamp will be applied.
 3. Thirdly, your document will be sent to the UAE Embassy in Moscow, where a Certificate of Legalisation will be added to the front page.
 4. Fourth, your document will be translated from Russian into Arabic, and subsequently notarised for acceptance in the UAE.
 - Finally, your document will be returned to the UAE and attested at the Ministry of Foreign Affairs (MOFA), before being sent back to you (or anywhere else you might need), safe and sound.
This process is the same across the board, though there can be some differences depending on the type of document you're trying to attest. For example, in the case of a Degree Diploma, it is often necessary to send the original copy of the completed degree to us before it can be attested. If it isn't possible for you to get the original copy though, it isn't a problem. We can help you legalise the copy of the Diploma, though there will be an extra charge.
In terms of the translation, costs will vary depending on the number of characters needing to be translated on your document. Please contact us for more information.

Why Vital Certificates?
As you can see, attesting a document can be quite complicated! Not to worry. Vital Certificates can handle the attestation process from end-to-end, regardless of the type of document you're trying to attest, which means you can sit back, relax and let us do the work.
We've helped thousands of clients have their documents attested, and haven't once had a document rejected in the UAE. Using our UAE attestation service gives you complete peace of mind and ensures that you get what you require in a timescale to suit your needs. Our staff are in constant contact with our legalisation partners in Russia, and as such are fully aware of the steps required to make sure your attestation goes smoothly.
Client Feedback
"This morning I received my attested documents back from you. They arrived by courier.
Firstly, I was very cautious about sending both my Russian wedding certificate and son's Kazakh birth certificate to you for UAE attestation services. The absolute difficulties and expense that could occur from trying to obtain replacement certificates should they have been lost is just simply incalculable. Anybody who has lived within these former CIS states will absolutely understand the challenges faced by anyone trying to obtain copies of original certification, let alone someone living outside these nation states. My fears were unfounded. You delivered prompt, efficient service and from start to finish the process took 29 days. This includes the courier time from when I sent the documents to your office in UAE from Thailand to me receiving the attested documents back in my hands.
Thank you again for your prompt, efficient service."

text: Economic analysis to aid in the implementation of public policy made major strides in the 1960s when organizations such as the Rand Corporation and Resources for the Future began systematically applying benefit–cost analysis (BCA) to regulatory choices. A further burst of enthusiasm for economic analysis swept the policy world in the 1970s and 1980s. This surge gained momentum from the nearly revolutionary impact of economist Alfred Kahn and his merry band of academic warriors who disrupted long-standing political equilibria, brandishing economic analysis as their primary offensive weapon. The movement garnered support from the White House in both the Carter and Reagan administrations. During the latter an Executive Order issued in 1981 mandated that executive branch regulatory agencies formally include benefit–cost analysis in their evaluation of rules. The BCA approach was likewise endorsed by the George H.W. Bush, Clinton, George W. Bush, and Obama administrations to follow.

Isolated Storage
For desktop apps, isolated storage is a data storage mechanism that provides isolation and safety by defining standardized ways of associating code with saved data. Standardization provides other benefits as well. Administrators can use tools designed to manipulate isolated storage to configure file storage space, set security policies, and delete unused data. With isolated storage, your code no longer needs unique paths to specify safe locations in the file system, and data is protected from other applications that only have isolated storage access. Hard-coded information that indicates where an application's storage area is located is unnecessary.
Important note Important
Isolated storage is not available for Windows Store apps. Instead, use the application data classes in the Windows.Storage namespaces included in the Windows Runtime API to store local data and files. For more information, see Application data in the Windows Dev Center.
This topic contains the following sections:
When an application stores data in a file, the file name and storage location must be carefully chosen to minimize the possibility that the storage location will be known to another application and, therefore, will be vulnerable to corruption. Without a standard system in place to manage these problems, developing ad hoc techniques that minimize storage conflicts can be complex, and the results can be unreliable.
With isolated storage, data is always isolated by user and by assembly. Credentials such as the origin or the strong name of the assembly determine assembly identity. Data can also be isolated by application domain, using similar credentials.
When you use isolated storage, your application saves data to a unique data compartment that is associated with some aspect of the code's identity, such as its publisher or signature. The data compartment is an abstraction, not a specific storage location; it consists of one or more isolated storage files, called stores, which contain the actual directory locations where data is stored. For example, an application might have a data compartment associated with it, and a directory in the file system would implement the store that actually preserves the data for that application. The data saved in the store can be any kind of data, from user preference information to application state. For the developer, the location of the data compartment is transparent. Stores usually reside on the client, but a server application could use isolated stores to store information by impersonating the user on whose behalf it is functioning. Isolated storage can also store information on a server with a user's roaming profile so that the information will travel with the roaming user.
Back to top
A quota is a limit on the amount of isolated storage that can be used. The quota includes bytes of file space as well as the overhead associated with the directory and other information in the store. Isolated storage uses permission quotas, which are storage limits that are set by using IsolatedStoragePermission objects. If you try to write data that exceeds the quota, an IsolatedStorageException exception is thrown. Security policy, which can be modified using the.NET Framework Configuration Tool (Mscorcfg.msc), determines which permissions are granted to code. Code that has been granted IsolatedStoragePermission is restricted to using no more storage than the UserQuota property allows. However, because code can bypass permission quotas by presenting different user identities, permission quotas serve as guidelines for how code should behave rather than as a firm limit on code behavior.
Quotas are not enforced on roaming stores. Because of this, a slightly higher level of permission is required for code to use them. The enumeration values AssemblyIsolationByRoamingUser and DomainIsolationByRoamingUser specify a permission to use isolated storage for a roaming user.
Back to top
Using isolated storage enables partially trusted applications to store data in a manner that is controlled by the computer's security policy. This is especially useful for downloaded components that a user might want to run cautiously. Security policy rarely grants this kind of code permission when you access the file system by using standard I/O mechanisms. However, by default, code running from the local computer, a local network, or the Internet is granted the right to use isolated storage.
Administrators can limit how much isolated storage an application or a user has available, based on an appropriate trust level. In addition, administrators can remove a user's persisted data completely. To create or access isolated storage, code must be granted the appropriate IsolatedStorageFilePermission permission.
To access isolated storage, code must have all necessary native platform operating system rights. The access control lists (ACLs) that control which users have the rights to use the file system must be satisfied..NET Framework applications already have operating system rights to access isolated storage unless they perform (platform-specific) impersonation. In this case, the application is responsible for ensuring that the impersonated user identity has the proper operating system rights to access isolated storage. This access provides a convenient way for code that is run or downloaded from the web to read and write to a storage area related to a particular user.
To control access to isolated storage, the common language runtime uses IsolatedStorageFilePermission objects. Each object has properties that specify the following values:
 - Allowed usage, which indicates the type of access that is allowed. The values are members of the IsolatedStorageContainment enumeration. For more information about these values, see the table in the next section.
 - Storage quota, as discussed in the preceding section.
The runtime demands IsolatedStorageFilePermission permission when code first attempts to open a store. It decides whether to grant this permisson, based on how much the code is trusted. If the permission is granted, the allowed usage and storage quota values are determined by security policy and by the code's request for IsolatedStorageFilePermission. Security policy is set by using the.NET Framework Configuration Tool (Mscorcfg.msc). All callers in the call stack are checked to ensure that each caller has at least the appropriate allowed usage. The runtime also checks the quota imposed on the code that opened or created the store in which the file is to be saved. If these conditions are satisfied, permission is granted. The quota is checked again every time a file is written to the store.
Application code is not required to request permission because the common language runtime will grant whatever IsolatedStorageFilePermission is appropriate based on security policy. However, there are good reasons to request specific permissions that your application needs, including IsolatedStorageFilePermission.
Back to top
The allowed usage specified by IsolatedStorageFilePermission determines the degree to which code will be allowed to create and use isolated storage. The following table shows how the allowed usage specified in the permission corresponds to types of isolation and summarizes the security risks associated with each allowed usage.
Allowed usage
Isolation types
Security impact
No isolated storage use is allowed.
There is no security impact.
Isolation by user, domain, and assembly. Each assembly has a separate substore within the domain. Stores that use this permission are also implicitly isolated by computer.
This permission level leaves resources open to unauthorized overuse, although enforced quotas make it more difficult. This is called a denial of service attack.
Same as DomainIsolationByUser, but store is saved to a location that will roam if roaming user profiles are enabled and quotas are not enforced.
Because quotas must be disabled, storage resources are more vulnerable to a denial of service attack.
Isolation by user and assembly. Stores that use this permission are also implicitly isolated by computer.
Quotas are enforced at this level to help prevent a denial of service attack. The same assembly in another domain can access this store, opening the possibility that information could be leaked between applications.
Same as AssemblyIsolationByUser, but store is saved to a location that will roam if roaming user profiles are enabled and quotas are not enforced.
Same as in AssemblyIsolationByUser, but without quotas, the risk of a denial of service attack increases.
Isolation by user. Typically, only administrative or debugging tools use this level of permission.
Access with this permission allows code to view or delete any of a user's isolated storage files or directories (regardless of assembly isolation). Risks include, but are not limited to, leaking information and data loss.
Isolation by all users, domains, and assemblies. Typically, only administrative or debugging tools use this level of permission.
This permission creates the potential for a total compromise of all isolated stores for all users.

Sometimes it is helpful to verify a change to isolated storage by using the file system of the operating system. You might also want to know the location of isolated storage files. This location is different depending on the operating system. The following table shows the root locations where isolated storage is created on a few common operating systems. Look for Microsoft\IsolatedStorage directories under this root location. You must change folder settings to show hidden files and folders in order to see isolated storage in the file system.

Species Hierarchy
Common name: SPRUCE - WHITE
Scentific name: PICEA GLAUCA
Species Info:
This lifeform is found north of the Mason Dixon line in North America.
White Spruce (Picea glauca - older literature, Picea canadensis) is found coast to coast in Canada and widely in Alaska. This species avoids the warmer coastal areas of the Pacific Northwest. It extends into the United States in several places such as northern Wisconsin and Minnesota. It is usually found near water and typically grows up to 70 feet tall, although older records indicate it can grow up to 110 feet tall. The needles are less than one inch long, and generally are located on the upperside of the branch. The cones are less than 2.5 inches long.
Spruces (Genus picea) are found in the colder climates of the Northern Hemisphere. These are a group of Gymnosperms that have stiff evergreen needles that grow singly along the branches. The cones also hang. There are about 40 species in this genus worldwide. China is blessed with about eighteen species. Seven species of spruces are native to North America, and there is also a European species (Picea abies) that has become established in North America. Because of their beauty many species are frequently planted as ornamentals.
These seven native North American species are listed below. All seven species are pictured and discussed herein. (*denotes discussed and pictured herein).
 SPECIES LOCATION
 *Picea breweriana (brewer spruce) NW USA (Local)
 *Picea engelmanni (engelmann spruce) Rocky Mountains
 *Picea glauca (white spruce) Alaska & most of Canada
 *Picea mariana (black spruce) Alaska & most of Canada
 *Picea rubens (red spruce) New England & E. Canada
 *Picea pungens (blue spruce) Colorado & Adjacent
 *Picea sitchensis (sitka spruce) Coastal Pacific NW
The following brief summary might help separate the spruces of the eastern USA.:
 White spruce (Picea glauca) is found across Canada and south into the United States to Maine and northern New York, Michigan, and South Dakota. The branches are horizontal and the tree has a pyramidal shape. The needles are form 2.0 to 2.5 cm long and the cones are from 3 to 6 cm long.
 Red spruce (Picea rubens) is found in eastern northern North America. This species has drooping branches and a pyramidal shape. The needles are from 1.2 to 2.0 cm long and the cones are from 3 to 5 cm long.
 Black spruce (Picea mariana) is found from Maine west to Alaska. This species has an unusual spire shape with relatively short branches. The short needles are from.8 to 1.2 cm long and the cones are from 1.5 to 2.5 cm long.
 Norway spruce (Picea abies) has many named garden varieties. This European species is a common ornamental. The needles are from 1.2 to 2.0 cm long, and the very long cones are from 10 to 17 cm long. The tigertail spruce (Picea polita) is native to the Orient. It is an occasional ornamental with upwards spreading branches. The needles are about 2.5 cm long and the cones are from 7-10 cm long.
 The blue spruce (Picea pungens) is native to Colorado, but is very widely and very commonly planted as an ornamental. The needles are from 2.5 to 3.5 cm long, and the cones are up to 8 cm long. The very unusual blue color of the needles will help identify this species.
Following is an incomplete list of some of the Eurasian Spruces (*denotes the species is discussed herein):
SPECIES LOCATION
*Picea abies(Norway spruce) Northern Europe
*Picea meyeri N. China
*Picea omorika Balkans of Europe
*Picea polita Orient
*Picea wilsonii C&W China
North American Pine family contains many valuable species.
Pines and Spruces, etc. (Family Panacea) comprise a group of about nine genera and about 195 species found worldwide. The family is of tremendous economic importance for building lumber. This group is also one of the most predominant forms of vegetation on much of the earth's land area. There are several important genera in this family, including the Firs (Abies), Spruces (Picea), Pines (Pinus), and Douglas Firs (Pseudotsuga).
Conifers (Order Coniferae) is an important group of trees and bushes found throughout the world. Although very common in the forests everywhere, this group of plants has only about 520 species. They are characterized by having needles. Pine trees and spruce trees are typical examples of conifers.
Gymnosperms are a group of trees and bushes usually characterized by needles and the production of cones to support the seeds. Most species are evergreen. (The actual technical definition has to do with the method of producing the seed.)
There are over 600 species of Gymnosperms known to science. The largest genus in this group in terms of species is the Pine genus with about 120 species. The second most common genus is the Podocarpus genus which is normally a more tropical group than the Pines.
Kartesz lists 135 species as growing in greater North America, including Hawaii, Puerto Rico, and the Virgin Islands.
Seed plants (Phylum Embryophyta) are generally grouped into one large phylum containing three major classes: the Gymnosperms, the Monocots, and the Dicots. (Some scientists separate the Gymnosperms into a separate phylum and refer to the remaining plants as flowering plants or Angiospermae.)
For North American counts of the number of species in each genus and family, the primary reference has been John T. Kartesz, author of A Synonymized Checklist of the Vascular Flora of the United States, Canada, and Greenland (1994). The geographical scope of his lists include, as part of greater North America, Hawaii, Alaska, Greenland, Puerto Rico, and the Virgin Islands.
Kartesz lists 21,757 species of vascular plants comprising the ferns, gymnosperms and flowering plants as being found in greater North America (including Alaska, Hawaii, Greenland, Puerto Rico and the Virgin Islands).
There are estimates within the scientific world that about half of the listed North American seed plants were originally native with the balance being comprised of Eurasian and tropical plants that have become established.
Plant kingdom contains a large variety of different organisms including mosses, ferns, and seed plants. Most plants manufacture their energy from sunlight and water. Identification of many species is difficult in that most individual plants have characteristics that have variables based on soil moisture, soil chemistry, and sunlight.
Because of the difficulty in learning and identifying different plant groups, specialists have emerged that study only a limited group of plants. These specialists revise the taxonomy and give us detailed descriptions and ranges of the various species. Their results are published in technical journals and written with highly specialized words that apply to a specific group.
On the other hand, there are the nature publishers. These people and companies undertake the challenging task of trying to provide easy to use pictures and descriptions to identify those species.

Omu Tou Recipe| Ghanaian Cuisine
Omu Tuo is a Ghanaian delicacy that is usually prepared with rice. But one thing that makes it unique from any other regular rice dish is its preparation process. Typically, the rice is prepared until it's soft and then pounded to form sticky balls. When pounded, you may mistake them for Ugali.
The dish goes well with soups like peanut stew, groundnut soup, or palm nut soup. Although Omu Tuo is common among the Hausa people, it has spread to other parts of Ghana and beyond.
Today, we will walk you through the recipe and all that you need to prepare yours. But before then, let us have an overview of Ghanaian culture.
Ghana Culture
Ghana is home to over 100 ethnic groups with the Akans, Ewes, Gas, and Moshi-Dagbanis being the largest tribes. Just like its ethnic groups, its culture is very diverse. Though some groups may share some cultural practices, each tribe has its practices, which sets them apart from others.
Maintaining honor, dignity, and a good reputation is crucial to the Ghanaians. The society maintains harmony regardless of their cultural and religious differences which makes their culture one.
Society treats people according to their age, position, wealth, and experience. Elderly people are accorded due respect and viewed as more wiser. Younger people go for advice from the elders and involve them in decision-making.
Dining Etiquette
Ghanaians are very welcoming and love sharing. During meals, dining etiquette is followed to the letter. When invited to a Ghanaian home, you are expected to leave your shoes outside. Getting yourself a seat or choosing where to sit is a sign of disrespect to the hosts. Always be patient and wait for the host to usher you in and show you where to sit.
Food is usually served in a communal bowl, and you are only allowed to begin eating from the front part. Before serving the meal, a basin of water is brought for everyone to wash their hands. After washing hands, you should wait until the male elders start enjoying their food.
In Ghana, you are not allowed to sit until you are shown where to sit Click To Tweet
Now, let's switch our focus to our Omu Tou recipe.
Serves: 2
Dish: side dish
Cuisine: Ghana
A cup of white long-rice
2 cups of water
½ teaspoon of salt
2 tbs butter
 1. Wash and rinse the rice to remove excess starch. The step is optional since the starch is required to improve the stickiness of the rice.
 2. Add water in a cooking pot and bring it to boil. Add butter and salt and cook it until the rice is soft. To achieve this, you need to lower the temperature of your heat-source to ensure the rice slowly boils until all the water is absorbed.
 3. Use a wooden spoon to pound the rice. Turn the rice to one side of the pot then to the other. Do this repeatedly until the rice is mushy.
 4. Serve by putting in a wet bowl and swirling until the bowl is formed.
 5. Serve with peanut soup stew or any soup of your choice
Note: To enjoy the meal, you need to ensure that the ratio of water, salt is perfect. You can also incorporate your favorite spices to enhance the taste.

How Does IBD Affect Your Sex Life?
How Does IBD Affect Your Sex Life?
Painful sex is a common IBD associated complication. Consulting a doctor is necessary. People suffering from inflammatory bowel disease (IBD) are always concerned about their intimacy. They tend to hide their emotions and feel embarrassed to converse about their problems to a doctor or nurse. In majority of the IBD cases, the sexual life of people remains unaffected. But during a flare-up, people may exhibit a lack of interest in sexual activities. Fortunately, along with IBD, the psychological issues associated with it can also be medically addressed.
If other treatment options become invalid for treating a certain IBD case then the doctors recommend surgery. It is important that the patient discusses everything with the partner and clearly thinks through before signing up for this option. Surgery is usually the last option and is only done for the betterment of patient's health.
Surgery As A Treatment Option For IBD
Fish Oil Benefits For Male Sexual Health ImageAs stated above, the doctor only recommends surgery when it is the only treatment option left. Surgery can provide a cure for patients with ulcerative colitis. However, for patients with Crohn's disease, surgery may offer relief for a certain episode. It may also help the patients who have multiple parts of their intestine affected badly.
Majority of the patient who undergo surgical procedures for the treatment of IBD recover completely and successfully with only some minor complications. However, the patient must be educated thoroughly about the few changes that may occur after the completion of the surgery.
Post-Surgery Changes In Women
 - Reduced sex drive or in other word diminished or low libido. This change may occur due to patient's own perception about her looks and body and the patient may think that she is less attractive after the surgery.
 - Reduction of sexual feelings and poor sex drive can lead to vaginal dryness. Even if the intercourse is done, it is uncomfortable, painful and short-lasting. This can be handled with switching to a different sex position which may embark excitement and may help in arousal.
 - Using a lubricant gel may also help in alleviating the pain associated with sex. Talking to the partner and discussing new exciting horizons to the relationship can have a positive impact. In order to feel better the patient must first find herself attractive.
Post-Surgery Changes In Men
Surgery, at times, may damage or cut the nerves present around the genital organs located near the bowel area. As a result, the patient may find difficulty in obtaining a strong erection or even ejaculating. Most of times the nerves recover back to the normal state but it may take a couple or more years to happen. Seeking the partner's patience will help in exploring other methods for gaining sexual pleasure.
