IntroductionThis feature allows organization administrator to configure a check to prevent duplicates. For example, in an event registration workflow, the administrator can configure the system to accept only one application per email address.
How to design
Define Document Key
The first step to set up the unique document check is defining the unique document key. This key usually contains placeholders which can be replaced by the system values or field values entered on the form.
In the example above, we will set up our document key as in below in VARIANT tab:
The expression above contains the workflow ID, the document owner id (the end-user who creates the document), and the email address entered on the form. This expression will ensure that only one email address can be used for submitting a registration application.
Specify the action to enforce the unique document check
The company administrator needs to indicate which action the unique document check rule should be enforced. In the event registration example above, we would like the system to prevent duplicates only when the user is submitting or resubmitting an application.
To do so, the company administrator can select "Check for unique document key" option as in the demonstration below:

The application of liquid strains to the factory production of enoki mushroom is the inevitable tren
Enoki mushroom is one of the main varieties of factory cultivation of edible fungi in my country. At present, factory cultivation has become the main production mode of enoki mushroom, and it is an inevitable trend of future development for liquid strains to gradually replace solid strains for the production of enoki mushroom. Carrying out the research and development of enoki mushroom liquid strains and industrial production applications can effectively improve the economic benefits of enterprises and promote the sustainable development of the industry.
1. Culture medium
The preparation of enoki mushroom liquid strain mainly involves three kinds of culture media, namely PDA solid medium, shake flask fermentation medium and fermenter medium. A variety of shake flask fermentation medium and fermentation tank medium formulas have been reported, and they have achieved obvious results.
1.1 Shake flask fermentation medium
Formula 1: Glucose 20g, peptone 2g, potassium dihydrogen phosphate 1g, magnesium sulfate 0.5g, trisodium citrate 1g, calcium chloride 0.1g, ferrous sulfate 1mg, manganese sulfate 1mg, VB10.1μg, VB20.1μg, water 1000mL.
Formula 2: Soluble starch 40g, glucose 10g, peptone 3g, potassium dihydrogen phosphate 1g, magnesium sulfate 0.5g, VB110μg, VB250μg, water 1000mL.
1.2 Fermenter culture medium
Recipe 1: 150g potato, 30g bran, 20g sucrose, 1g potassium dihydrogen phosphate, 0.5g magnesium sulfate, 1000mL water.
Formula 2: 40g soybean meal powder, 10g white granulated sugar, 1g potassium dihydrogen phosphate, 0.5g magnesium sulfate, VB1100μg, VB2500μg, 1000mL water.
Recipe 3: 50g corn flour, 30g bran, 1g potassium dihydrogen phosphate, 0.5g magnesium sulfate, VB10.1μg, VB20.5μg, water 1000mL.
In the fermentation tank culture medium, generally add an appropriate amount of antifoaming agent, such as polydimethylsiloxane emulsion, etc., which can effectively prevent the formation of foam and avoid the influence of foam on the fermentation process of liquid bacteria.
2. Liquid strain preparation process
In the preparation process of the industrialized liquid strain of enoki mushroom, in order to effectively shorten the growth cycle and avoid unnecessary pollution, companies often use shake flask liquid seeds directly into the fermentation tank culture medium. The specific process is: test tube or flat solid strain → Shake flask fermentation → fermentation tank strains → inoculation of cultivation materials. The specific process is as follows:
2.1 Plate inoculation of bacteria
Choose PDA plate medium, inoculate a bacterial seed block with a diameter of about 0.5 cm in the center of the plate, and cultivate it at 25°C. The aerial hyphae of enoki mushroom are well developed, and the whole plate can be covered in 6~7 days. It is recommended to use a flat plate (9cm petri dish) to cultivate solid strains. First, it is helpful to observe the growth of aerial hyphae of strains, and the other is to punch holes from the edge of the colony.
2.2 Shake flask fermentation culture mycelium
Use a 1000mL shake flask to fill 600mL fermentation medium and sterilize it for later use. Use a hole puncher to punch holes from the edge of the plate colony and inoculate them into the shake flask fermentation medium. The inoculation amount is 8-10 solid strains (diameter 5mm). Rotate at 160r/min and incubate at 23°C for 6-7 days. In order to prevent the mycelium balls from condensing together, a magnetic stirrer can be used to break up the mycelium blocks in the seed liquid.
2.3 Fermentation tank inoculation strains
A 1 000L pneumatic fermenter is used to load 800L of fermentation medium, which is autoclaved and steam sterilized for later use. The inoculum amount is 1%~2%. After 6~7 days of cultivation at 23℃, it can be placed in the pot and used for inoculation of cultivation material.
3. Matters needing attention
3.1 Prevent contamination by bacteria
Liquid strain seed production has high efficiency and is easy to realize factory operation, but the contamination of bacteria is a problem that cannot be ignored in the liquid strain preparation process. In particular, small and medium-sized enoki mushroom production enterprises have weak anti-risk capabilities. Once contamination by bacteria occurs, it is very likely to cause bankruptcy. There are three main reasons for the contamination of bacteria: one is technical operation problems; the other is leakage of fermentation tanks and auxiliary equipment; the third is bacterial contamination.
In response to the above problems, it is recommended that companies take the following measures to control the risks to the lowest extent. Regularly train technical operators to improve their theoretical and operational levels; establish operating specifications for fermentation workshops and guide technicians to operate in accordance with the regulations; regularly inspect and maintain equipment to avoid leakage of equipment; regularly carry out strain purification and inspection work, and use Use plate culture, microscope observation and other methods to determine whether the bacteria are infected with other bacteria in time.
3.2 Maintain stable strains
Strains are the core of an enterprise's production, and maintaining the stability of strains is the key to high and stable production. Enterprises should conduct sampling inspections of liquid bacteria once a week. The detection methods include back-up plate culture and microscopic observation. The quality of the bacteria can be preliminarily judged by observing the production status of aerial hyphae and whether there is lock-like association or not, so as to prevent the degradation of the bacteria. Cause irreparable losses to the enterprise. The study found that the use of LBL liquid medium with bromothyfen blue can eliminate severely degraded strains, and the severely degraded strains have poor decolorization ability. It is recommended that manufacturers can promote it.

We review the records of published and unpublished sightings and strandings for Risso's dolphin (Grampus griseus) in subantarctic waters of the Southwestern South Atlantic Ocean. Based on 59 sighting (n = 521 individuals) and 33 stranding records (n = 88 individuals), we identified three main areas of Risso's dolphin concentration in Patagonian waters, which have been observed mostly during the austral summer. We were unable to find published or unpublished reports of Risso's dolphin in offshore or over deep-water areas in this region. Future studies covering other potential areas of the species' distribution are important to improve the scarce information known for this dolphin in this area.

Growth and Inequality: The Case of Indonesia, _PHONE_
Download (259kB) | Preview
This paper investigates whether the 'Kuznets hypothesis', that economic growth from low levels of GDP per capita is initially associated with an increase in income inequality and later followed by a decline in inequality, is supported by evidence for a less-developed country, Indonesia. The paper outlines the relevant features of the process of rapid growth and structural change, in particular industrialisation since the 1960s. It notes the possible consequences of this process for changes in income distribution, and draws on disparate sets of statistical data to trace trends in income inequality in Indonesia. The paper concludes that the evidence for Indonesia suggests an increase in inequality during the 1970s and a subsequent decrease of inequality until 1997. A comparison of the evidence with historical data for the UK and Japan suggests that income inequality in Indonesia was relatively low.

Measuring the Predictive Accuracy of the Correlated Gamma Ratio Method for Model Selection
Proceedings of the 5th Hellenic-European Conference on Computer Mathematics and its Applications, Athens, Greece, E.A. Lypitakis (ed.), pp.732-739, 2001

Autoregressive Conditional Heteroscedasticity (ARCH) models have successfully been applied in order to predict asset return volatility. Predicting volatility is of great importance in pricing financial derivatives, selecting portfolios, measuring and managing investment risk more accurately. In this paper, a number of ARCH models are examined in the framework of a method for model selection based on the Correlated Gamma Ratio (CGR) distribution and their ability to predict future volatility is examined. According to this method, the ARCH model with the lowest sum of squared standardized forecasting errors is selected for predicting future volatility. A number of evaluation criteria are used to examine the performance of a model to predict future volatility, for forecasting horizons ranging from one day to one hundred days ahead. The results show that the CGR model selection procedure has a satisfactory performance in selecting that model that generates "better" volatility predictions. It appears, therefore, that it can be regarded as a tool in guiding one's choice of the appropriate model for predicting future volatility, with applications in evaluating portfolios, managing financial risk and creating speculative strategies with options.
Keywords: ARCH models, forecast volatility, model selection, predictability, correlated gamma ratio distribution

Featured on House and Grey's Anatomy, the disorder is called superior canal dehiscence syndrome. It is a very rare condition that affects the ear, allowing it to hear sounds inside the body.
Little is known about it, but it's thought that.5% of people have it on some level. Typically, it affects people around 40 years old. The problem is with the superior canal part of the ear.
Overlying the superior canal is the temporal bone. In this disorder, that bone is thinner than it is meant to be (normally due to improper development). Typical symptoms include hearing your own speech or other noises in the body (like eye movements) very loudly, balance problems (because of the inner ear's role in keeping balance), and rapid eye movement.
If this makes you feel paranoid that you have it, a normal CT scan can determine it, though it's highly unlikely that you do. The disorder can be treated by surgery relatively easily. Whether you only think you have it or you genuinely do, you can rest assured knowing either way it's all in your head.

IZA DP No. 4414: Who Compares to Whom? The Anatomy of Income Comparisons in Europe
published in: Economic Journal, 2010, 120 (544), 573-594
This paper provides unprecedented direct evidence from large-scale survey data on both the intensity (how much?) and direction (to whom?) of income comparisons. Income comparisons are considered to be at least somewhat important by three-quarters of Europeans. They are associated with both lower levels of subjective well-being and a greater demand for income redistribution. The rich compare less and are more happy than average when they do, which latter is consistent with relative income theory. With respect to the direction of comparisons, colleagues are the most frequently-cited reference group. Those who compare to colleagues are happier than those who compare to other benchmarks; comparisons to friends are both less widespread and are associated with the lowest well-being scores. This is consistent with information effects, as colleagues' income arguably contains more information about the individual's own future prospects than do the incomes of other reference groups. Last, there is some evidence that reference groups are endogenous, with individuals tending to compare to those with whom they interact the most often.

The Centre participated in the KM3NeT project, which involved the recent installation of the first 400-meter tall underwater neutrino observation system at depth of 3500 meters off the coast of Sicily.
The Italian Institute for Nuclear Physics (INFN), which leads the KM3NeT-Italia undersea neutrino telescope project, has recently announced the successful installation of the first of a number of 400-meter tall underwater towers with optical, acoustic and oceanographic sensors. In 2009 NURC's (now CMRE) deep water low noise hydrophone technology, developed in collaboration with the Italian company SMID, was selected as acoustic sensors for the system. The neutrino telescope is a European deep-sea one cubic kilometer research infrastructure operating at the bottom of the Mediterranean Sea, off the southeastern coast of Sicily.
The SMID-CMRE hydrophones are part of the acoustic positioning system of the cubic kilometer scale telescope and will be mounted on the towers constituting the telescope. The acoustic positioning system helps determine the accurate positions of the towers during the deployment and will support the operation phase of the telescope. The knowledge of the towers positions are needed in order to know the location of optical modules (OMs) mounted with them. The OMs would be used to reconstruct the tracks of the neutrinos detected from the optical sensors. CMRE has developed a procedure for hydrophone calibration under high hydrostatic pressure.


Valves for abrasive materials
What's the Best Slide Gate or Diverter Valve for Handling Coal, Frac Sand, and Fly Ash?
Many of our customers come from industries where conveying abrasive material is a recurring challenge. Configuring the right slide gates and diverter valves for those customers is a challenge in its own right. In this article, we'll take a look at some of the key factors that influence the decision of which slide gate or diverter valve works best for handling these abrasive materials.
Different Level of Material Hardness Cause Different Levels of Wear
Abrasion occurs where the metal components of a valve are worn down through friction as the material handled impacts those components. Prior to considering what type of gate or diverter is required, special consideration has to be given to the characteristics of the material and how it is being conveyed.
Minerals are categorized into a Mohs hardness scale. The scale characterizes the scratch resistance of various minerals by how a harder material can scratch a softer material. Softer materials like talc have a hardness rating of 1, while harder materials like diamonds have a hardness rating of 10. When selecting metal valve components, it's best to select the proper construction materials that match the hardness of the material handled.
Material Shape Has an Impact on the Effects of Abrasion
The shape of the material being handled is another important consideration. Sand can have a Mohs hardness rating of 7. Sand exists in a variety of shapes. Some sand particles can be round while others can be angular. An angular particle will abrade valve components much faster than a rounded one.
How the material is handled is yet another consideration. For example, is the material being gravity fed through the valve or is the material being conveyed pneumatically through a conveying system at 3,000 feet per minute? Talc, one of the softest minerals, can eventually chisel its way through a substantial metal plate if given a small exit hole and considerable force behind it.
Hard Metal Wear Liners can Alleviate Component Breakdown
Utilizing hard metals or metal alloys for the wear areas is always a consideration. Valves may be manufactured incorporating abrasion resistant plates, chromium carbide overlays, or metals like Hastelloy® to reduce wear from abrasion. Diverters may be manufactured with replaceable wear liners that are constructed of the above-mentioned materials.
Replaceable Abrasion Resistant LinersOver time, worn liners may be replaced with new ones to extend the life cycle costs to the valves. In some instances, an added feature as simple as an interior rock box might be added to address abrasion and prolong valve life. A rock box is an area within the valve that is designed to trap a small amount of the material handled. Subsequent material traveling through the valve impacts on the trapped material as opposed to abrading a liner or plate. When cross contamination of the material is not an issue, this feature is extremely effective.
Manufacturing Experience with Abrasives is Critical
Companies that deal with abrasive products are cognizant of the fact that new equipment begins to wear out starting day one. Equipment installed in these environments needs to be continually maintained. Sourcing valves from an established supplier with the ability to provide support after the installation can help lift the burden of dealing with challenging applications. Their expertise can address the many factors experienced in a particular application and assure the purchase of the best slide gate or diverter valve for handling abrasive materials.

Let $X$ be a complex manifold and $g$ a hermitian metric on $X$. Consider the Riemannian exponential $\exp_p: T_p X \to X$.
If $\exp_p$ is holomorphic for every $p \in X$, then $(\exp_p)^{-1}$, suitably restricted, provide holomorphic normal coordinates near $p$, with respect to which the metric osculates to order 2 to the standard metric at the origin. This shows that $g$ is a Kähler metric.
However, Kähler is not sufficient to ensure that $\exp_p$ is holomorphic: take $X$ a curve of genus $g \geq 2$. If $\exp_p:T_pX \to X$ is holomorphic, then it lifts to a holomorphic map from $T_pX$ to the universal cover $\widetilde{X} = \Delta$, giving a holomorphic map $T_pX \simeq \mathbb{C} \to \Delta$, which must be constant by Liouville's theorem. In fact, one can see that $\exp$ cannot be holomorphic if $X$ is Kobayashi hyperbolic.
This leaves the question: What are the hermitian manifolds/metrics whose exponential map is holomorphic?

In the $1$ complex dimension case this forces the metric to be locally isomorphic to the standard metric. The exponential map preserves length in the radial direction, so if it is conformal then it must also preserve length in the other direction. – Tom Goodwillie Jun 16 '11 at 3:52

NB: I've had a little time to think about this and can now improve my answer, in particular, removing the real-analytic assumption, which, as I suspected, was not necessary. Here is the improved answer:
If the metric $g$ is Kähler, then having the exponential map from a point $p\in M$ be holomorphic makes it flat in a neighborhood of $p$.
Suppose that $\exp_p:T_pM\to M$ is holomorphic near $0_p\in T_pM$ (where we use the natural holomorphic structure on the complex vector space $T_pM$). Let $z:T_pM\to\mathbb{C}^n$ be a complex linear isometry, so that the hermitian metric on $T_pM$ is just $|z|^2$ in the usual sense. Let $Z$ be the holomorphic 'radial' vector field on $\mathbb{C}^n$, whose real part is the standard radial vector field on $\mathbb{C}^n$.
Then $$ {\exp_p}^*g = g_{i\bar j}(z)\ dz^i\ d\overline{z}^j $$ for some functions $g_{i\bar j}$ on a neighborhood of $0\in\mathbb{C}^n$. Since $g$ is Kähler, there is a function $f$ defined on a neighborhood of $0\in\mathbb{C}^n$ such that $$ g_{i\bar j} = \frac{\partial^2f}{\partial z^i\ \partial\overline{z}^j}. $$
Now, the condition that $z$ furnish Gauss normal coordinates for ${\exp_p}^*g$ is easily seen to be that
$$ \mathcal{L}_Z\bigl(\bar\partial f\bigr) = \bar\partial\bigl(|z|^2\bigr). $$ In particular, $ \bar\partial\bigl(\mathcal{L}_Z(f - |z|^2)\bigr) = 0$, so $\mathcal{L}_Z(f - |z|^2) = h$ for some holomorphic function $h$ on a neighborhood of $0$. This $h$ must vanish at $0$, so it is easy, by adding the real part of the appropriate holomorphic function to $f$ (which won't change $g$) to arrange that $h\equiv0$ and, moreover, that $f(0) = 0$. But this now implies that the real-valued function $f-|z|^2$ vanishes at the origin and also is constant along the radial vector field. Thus, $f = |z|^2$, and the metric $g$ is flat in these coordinates.

I do not like complex numbers and can make a mistake easily...
Let $L_p$ be a complex line in a tangent space $T_pX$. It is easy to see that $\exp_p$ gives an isometric embedding $L_p\hookrightarrow X$ which is also star-shaped with center at $p$; set $L=\exp_p(L_p)$
Take any other point $q\in L$, and let $L_q\subset T_q$ be the tangent subspace to $L$. Note that the maps $\exp_p$ and $\exp_q$ coinside (up to a shift) on the geodesic $(pq)$. [Here I use that if two holomorphic maps coincide on the real line then they coincide in the complex plane.] It follows that $L=\exp_q(L_q)$. Therefore $L$ is totally geodesic.
In other words: For any complex sectional direction in $X$, there is a tangent totally geodesic surface which is isometric to complex plane.
In particular, the sectional curvature in all complex sectional directions is zero and therefore the curvature of $X$ is identically zero; the later stated in Kobayashi--Nomizu, Foundations of differential geometry, Volume 2 IX, Prop. 7.1. (thanks to RdN).
share|improve this answer
I don't quite understand your arguement for exp of a complex line to be totally geodesic. But if so there is a lemma in vol II of Kobayashi Nomizu (Prop. 7.1) that says if two tensors with the symmetry and J invariance of a Kahler curvature tensor agree on complex lines they must be equal. It's clear curves have to be flat by Gauss lemma and totally geodesic would mean the second fundamental vanishes, so we can measure R of the ambient space from such curves. Thus the Prop. says total curvature must vanish. – RdN Jun 25 '11 at 16:43

 You need to join these two datasets together to make one dataset. The easiest way to do this is with Magic ETL. The below example shows you more than just joining, but the idea is that you can use the join tile to join your two datasets together. You would join on week. You might want to review this KB article to better understand the different types of joins if you are unfamiliar with the concept.

 Hi _USER_
 alternatively you can use a data set view to join your two datasets together.
 another option to think about might be instead of joining your data together you UNION / stack your data together such that you have
 Demo | 1 | 3
 Create | 1 | 10

 Sorry _USER_ and _USER_ hard disagree.
 Don't JOIN the data. APPEND them.
 If you get to the point where you have multiple rows per week OR if dataset 1 is at a different granularity than dataset2 then you end up with row growth (because you're JOINING) and you have to crazy math to 'SUM DISTINCT).
 1) add a constant "Activity Type" to each dataset so you know what type of metric you're dealing with
 2) duplicate the date column and call it "Activity Date" for both datasets. (then use Activity Date in Analyzer).
 3) UNION the data

 [in] Pointer to the IRootContainer interface object that serves as the parent to the widget to locate.
 - pw
 []:
 [in] Pointer to the IWidget object to be located.
 - ppRoot
 []:
 [in/out] Pointer to an IContainer pointer, into which the function will return a pointer to the container's root container. This parameter may be specified as NULL if the caller does not wish to get the root container.
 - prcRelative
 []:
 [in/out] Pointer to an AEERect. On input, this rectangle will specify the current relative offset of the 'pw' object relative to its child. On output, this rectangle specifies the layout position of the object relative to the root container. Therefore, the function should initially be called by passing in a rectangle with origin at (0, 0) -- otherwise, the returned rectangle will be expressed relative to the initial offset.
Prototype
 int IRootContainer_Locate(IRootContainer *pif,
 IWidget *pw,
 IContainer **ppr,
 AEERect *prc);
Return
 AEE_SUCCESS - If the widget 'pw' was found and the information requested was
 successfully returned
 AEE_EFAILED - If the widget 'pw' was not found in the container.
The rectangle occupied by the widget is returned in 'prcRelative'.
A pointer to the widget's root container will be returned in 'ppRoot', which will increment the reference count of the root container.
Side Effect
None
Comment
The rectangle referenced by 'prcRelative' MUST be initialized prior to calling IRootContainer_Locate(), otherwise the results will be undefined.
Since the root container is the container making the location request the pointer returned in 'ppRoot' will be the same pointer passed into the function in the 'pif' parameter.
The pointer passed in the 'ppRoot' parameter is a double-indirection -- i.e., it is a pointer to a pointer. Applications should use care in ensuring that the proper level of indirection is used in calling the function.

The Skincare Miracle Called "Centella Asiatica"
A new ingredient is making waves in the beauty community. More and more skincare companies are incorporating CentellaAsiatica in their products. CentellaAsiatica (also known as Asiatic pennyworth, Brahmi, tiger grass, cica, and gotu kola) is popular for one thing: its hydrating and anti-aging, skin-loving properties.
Origin Story: What Is Cica and Where Did It Come From?
Cica plant
CentellaAsiatica is a perennial herb that can be found primarily in Asian countries, such as India, Sri Lanka, Japan, and China. It can also be found in some parts of the US and Australia. Dubbed one of the "miracle elixirs of life," this small plant's medicinal properties are due to its high antioxidant content, which protects the body's neurons from oxidative damage due to free radicals.
For years, it enjoyed use as both a medicinal and culinary ingredient, but like most traditional plant extracts, it's now gaining popularity as an ingredient for skincare products.
This swamp-dwelling plant made its debut in South Korean cica creams a few years ago. Eventually, American brands like Estee Lauder began incorporating the ingredient in their products, although on an on and off basis over the years.
Western beauty brands call cica the "hottest new ingredient in skincare," while cica creams have become cornerstones of cult K-beauty products. But is CentellaAsiaticareally worth the hype?
Cica as a Super Skincare Wonder

CentellaAsiatica isn't just a fad — it offers benefits for different skin types, thanks to its active compounds.
Sensitive Skin
Many of cica's purported benefits boil down to its ability to calm inflammation. Madecassoside, an active compound in CentellaAsiatica, boosts antioxidant activity in your skin, reducing inflammation due to allergic reactions or wounds. It is a rich source of amino acids that soothe irritated or compromised skin.
Combined with other skincare ingredients (such as snail extract), CentellaAsiatica extract can cool the skin and reduce redness due to inflammation.
Oily and Acne-Prone Skin
Acne scarring is one of the top concerns of people with oily and acne-prone skin. Manage the symptoms of your acne by treating blemish scars with products rich in CentellaAsiatica. Its active compounds promote quicker skin tissue repair (fibroblast proliferation), as well as increases your skin's collagen production.
Unlike other acne treatments that use harsh astringents or alcohol, cica is a gentle, antibacterial solution for pimples. One of its active compounds, Madecassic acid, not only stops inflammation due to acne. It also aids in reducing acne breakouts.
All of these make cica a double whammy of an ingredient — it inhibits pimple formation and heals the scars acne can leave behind.
Dark Spots
If you want a clear complexion free of sun damage, you're in luck. Cica's madecassoside acid helps mitigate UV-induced hyperpigmentation.
Cica also repairs your skin's barriers after they are damaged to prevent pimples and other skin conditions like psoriasis and eczema. CentellaAsiatica's wound-healing properties prevent the inflammation of blemishes and scarring.
Dry Skin
If your skin is begging for some deep hydration, cica is a rich source of amino acids that aid in the maintenance of your skin's hydration levels.
As mentioned, cica can also repair your skin's barrier. A strong skin barrier means it can lock moisture in the skin and fight off environmental aggressors and free radicals, preventing them from irritating your complexion.
CentellaAsiatica also increases the blood flow to the skin, which ensures nutrients and oxygen are properly delivered to your skin cells, giving you a bright and radiant look.
Wrinkling and Aging Skin
CentellaAsiatica has high levels of skin-loving phytochemicals. It is rich in vitamin A, vitamin C, vitamin B1 and B2, carotene, and niacin. When you combine all of these vitamins and minerals, you get an extract that brightens your skin and fights premature aging.
Cica's high levels of antioxidants also promote better collagen production. One of the culprits behind skin aging is the decrease in the amount of Type 1 Collagen in the dermis, which is the layer between your subcutaneous tissue and epidermis. Asiaticoside, another active compound in cica, is an anti-wrinkle ingredient that induces the production of Type 1 collagen, which helps keep your skin youthful.
CentellaAsiatica's ability to boost collagen levels has also proved this herb's ability to treat cellulite.
Given the countless benefits related to cica extract, there's no denying that this ingredient is a must-have in your skincare regimen. You can add CentellaAsiatica to your daily routine in the form of Linovera Oil, a skin-friendly moisturizer designed to hydrate, rejuvenate, and brighten your skin.
Moisturize Your Skin with Linovera Oil
Linovera Oil
Linovera Oil's claim to fame is its use of the powerhouse botanical CentellaAsiatica. Developed by European skincare and reconstruction specialists, this everyday skincare product prevents premature skin aging, restores your skin's hydration, and reduces the appearance of dark spots.
Add Linovera Oil to your skincare routine to enhance your skin's moisture. This special oil softens dry and cracked heels, elbows, and other parts of your body. Its CentellaAsiatica content (combined with aloe vera and hyperoxygenated essential fatty acids) can moisturize even the driest skin conditions in the gentlest way possible.
Linovera Oil is ideal for the daily care of sensitive and fragile skin. We recommend using this moisturizing product for the following cases:
Linovera Oil might be in oil form, but its formula is light and non-sticky. Your skin will quickly absorb the formula, leaving it smooth, soft, and not sticky.
Instructions for Use
Linovera Oil has a clean application process thanks to its dosage pump. Simply apply a pump or two's worth of the oil to selected areas of your body. Massage the product gently with your fingertips to ensure the oil is distributed evenly. Repeat the application on the affected area two to three times per day.
A little Linovera Oil goes a long way. You don't need much of the product for it to fully spread on your face and body, saving you money on moisturizer! No matter what your skin type or skin condition is, CentellaAsiatica extract might be the best thing for nourishing your skin. Give your skin its daily dose of cica and other skin-loving nutrients by using Linovera Oil every day.

Silicon grease
I read where silicon grease is used to protect and lube your rubber weather seals. Does anyone know if you can buy that locally in auto stores. Also would that be the same as dieletric grease that you use for your spark plug boots. I think that is some type of silicon grease but don't know if its the same.
Thanks Roy
As far as I know, they are all the same thing. Most silicone compounds are practically identical. They are described as grease-like materials usually based on the dispersion of a silica-thickening agent in a dimethyl-silicone fluid. Thank goodness, it is just called silicone grease. They are used as a moisture barrier, surface protectant, dielectric insulator and for specialized release and lubrication. These compounds are not to be used for metal-to-metal load bearing lubrication.
Technically the term "dielectric" describes a property of something, not a type. It is the ability of a substance to resist the transmission of an electrostatic force from one charged body to another. In electronics the term "dielectric constant" is the measure of a materials ability to do this, the lower the value the greater the resistance. The label describes it use, rather than the type of material in the tube. So when you see a tube of "Dielectric Grease" you can be sure it is a tube of silicone compound.
Being water repellent, hydrolytically stable, non-corrosive, chemically inert, odorless, excellent dielectric properties, excellent coating ability (adheres when fluids would drip or spin off), and colorless are features that make them attractive.
You can see why their use in automotive connectors is so common, they stick when somethings will not, they do not corrode things, they repel water, they do not boil, or catch fire until greater than about 600 degrees Fahrenheit and are good insulators. Hope that helps.

Yep just what C5Phil said..
Your local parts house, PepBoys, K-Mart, Target and Wal-Mart probably have just what you are looking for in their automotive section..
I use the little tubes silicone that the Substation guys get from G.E. or Westinghouse for gasget material when working on Transformers.. Hey,, remember what C5Phil said..;).. It works great too :gap

Children affected by cerebral palsy often have difficult eating and maintaining a healthy weight. These problems may indicate the need to see a nutritionist.
Typically, people with cerebral palsy struggle with chewing because their upper and lower jaw do not fit together correctly, difficulty controlling their mouth muscles in order to chew properly, and pain or other unusual feelings throughout the mouth while eating.
Nutritionists can help you identify a healthy child for your diet that makes it easier for him or her to swallow. He or she may also identify special vitamins or supplements your child needs.

 someone who works underwater
 1. frogman(Noun)
 A diver, especially one in a diving suit (as opposed to one in scuba gear).
 2. frogman(Noun)
 A US Navy SEAL.
 1. Frogman
 A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity which includes combat. Such personnel are also known by the more formal names of combat diver, or combatant diver, or combat swimmer. "Combat swimming" is often used to mean "combat diving", but, according to some, strictly speaking means surface swimming without a breathing apparatus for coastal or ship infiltration. Such actions are a historical form of "frogman" activity and an important feature of naval special operations. The term '"frogman" is often popularly used to refer to a civilian scuba diver. The word arose around 1940 from the appearance of a diver in shiny drysuit and large fins. Though the preferred term by scuba users is "diver", the "frogman" epithet persists in informal usage by non-divers, especially in the media and often in reference to professional scuba divers such as in a police role. Some sport diving clubs include the word "Frogmen" in their names. In the U.S. military the United States Intelligence Community, divers trained in scuba or CCUBA who deploy for tactical assault missions are called "combat divers". This term is used to refer to the Navy SEALs, operatives of the CIA's Special Activities Division, elements of Marine Recon, Army Ranger RRD members, Army Special Forces divers, Air Force Pararescue, Air Force Combat Controllers and the Navy Explosive Ordnance Disposal units.

An investigation on the feasibility of sputtering a diamond block into a specially designed three-dimensional cutting tool shape using a focused ion beam (FIB) was carried out. The ion-sputtered removal rate, surface morphology and sputtered feature accuracy were evaluated with respect to the FIB parameters such as ion current and angle of ion incidence through sputtering pockets on the top surface of a diamond substrate. A single crystalline diamond tool, with 25 νm length in the cutting edge and smooth face quality, has been successfully fabricated by using a FIB. These excellent tool characteristics are proven in the results obtained from the machining experiments done on the ultra-precision machine.

text: Headcut erosion is usually associated with the consumption and transformation of flow energy that occurs when runoff is used to transport sediment. Therefore, flow energy variations in the headcut erosion process are critical in the loess gully region of the Loess Plateau. The aim of this study was to clarify the effects of the flow discharge and slope gradient on flow energy and the response of the headcut erosion process in the gully region of the Loess Plateau. This study examined the headcut erosion process using slope gradients ranging from 1° to 7° in the upstream catchment area and downstream gully bed and inflow discharges ranging from 3.6 to 7.2 m3·h-1. The results showed that the slope gradient has a significant impact on the potential energy in the upstream catchment area; thus, changes in the slope gradients produced changes in the sediment yield. Moreover, the flow discharge significantly influenced not only the potential energy but also the kinetic energy in the upstream catchment area and downstream gully bed. The kinetic energy at the downstream gully bed was 0.03~0.16 J·s-1 lower than that in the upstream catchment area due to the flow drop at the gully head. Greater energy consumption occurred at the gully head than in the upstream catchment area and downstream gully bed, and the gully head contribution to the flow energy consumption was 44.30~64.29%, which increased with increasing flow discharge and decreasing slope gradient. The influence of the slope gradient on the sediment yield was more significant than that of the flow discharge, and a nonlinear regression equation was developed to estimate sediment the yield. The flow energy consumption was significantly correlated with the sediment yield. These findings could improve our understanding of the flow energy characteristics and headcut evolution process during headcut erosion.

The average life span for African-Americans in Louisiana today (72.2 years) is shorter than that of Colombians, Vietnamese and Venezuelans. The average life span of an African-American in New Orleans is 69.3 years, nearly as low as life expectancy in North Korea.
African-Americans in Tangipahoa Parish have well-being levels of the average American in the early 1950s.
From the American Human Development Project's "Portrait of Louisiana," released today. More data on the state, like food stamp usage by parish, here.
Hurricane Katrina destroyed cities, jobs and lives. But for some children, the storm may have resulted in an unforeseen upside: better schooling.
A new working paper from Prof. Bruce Sacerdote at Dartmouth University notes that when families fled New Orleans, they were forced to abandon its failing school system. Professor Sacerdote used data on Louisiana students' test scores and college attendance, both before and after the Hurricanes Katrina and Rita, to calculate what effect leaving a failing school district had on academic achievement.
In the first year after the 2005 evacuation, students' standardized test scores fell — which is probably not surprising, given the disruption in their lives. Within a couple years, students originally from Orleans Parish schools saw their scores recover and then eventually surpass their prehurricane levels.
But this was not true for Katrina evacuees from nearby Jefferson and Rita evacuees from Lake Charles. In those areas, where the schools were better than those in New Orleans, the decline in test scores for displaced students persisted into 2007 and started to recover by 2008. Similar results were seen for college enrollment. Evacuated students from New Orleans saw a modest increase in four-year college enrollment, whereas their counterparts from the suburbs initially saw a negative effect on college enrollment (which disappeared within about a year).

If you're thinking about expanding your feathered family, you may be wondering whether a cockatiel and a budgie can live together. Or maybe your cockatiel and your budgie get along well, and you'd like to know if it's possible to save on space by keeping them in a single cage.
Let's go into whether a cockatiel and budgie can live together and why (not)!
Can a cockatiel and budgie live together?
These two parrot species are pretty similar in many aspects. They're both seed eaters that can naturally be found in Australia, where flocks of both sometimes forage side-by-side. The two are actually the most popular pet parrots available today (with budgies ranking #1 and cockatiels #2).
Both species are very intelligent and make great pets, but many folks think too lightly of adding one to their family. Although they're often seen as "beginner animals", they do need some special care, including plenty of space, attention and mental stimulation.
All this being said, unfortunately, it's generally still not recommended to keep a cockatiel and budgie in the same cage. Despite their many similarities, it can lead to stress for your birds. In rare cases, it can even turn out fatal. We'll go into why below.
The Psittacology household currently contains both budgies and cockatiels, and let me tell you from my own experience: these species are quite different in terms of personality.
Cockatiels are known for being among the more laid-back, calm parrots. Budgies… not so much. They're pocket rockets that seem to live life ten times faster than the average cockatiel.
Although you can let your cockatiel and budgie play in the same space under supervision, their personality differences alone make it a bad idea to make them live in one cage.
Budgies can be real pests, stressing out your 'tiel with their hyperactive and curious behavior. That's not too much of a problem in an open area (although you should still separate them if either appears stressed), but it can cause issues in an enclosed cage.
What happens if your budgie doesn't relent, and your cockatiel has nowhere to go? It isn't unheard of for budgies to nip at feet and eyes. Will the stress cause it to become ill? Will the cockatiel lash out, injuring its smaller cage mate?
Did you know? Cockatiels are prone to night frights if they get spooked during nighttime. A cockatiel's thrashing and flapping during one of these night frights can injure a budgie or cause it to injure itself in fright.
Speaking of being pests, budgies especially are known to become territorial about nesting areas. This is especially relevant in large aviaries that contain both species and feature nesting boxes. However, it can become an issue indoors as well.
What happens when your cockatiel or budgie becomes broody? They can start to view certain spaces in the cage as their nest and become violently protective of them. Suddenly, they won't be so tolerant towards the other species anymore, and things can easily get out of hand.
Again, it's unlikely for anyone to get hurt if the birds are on neutral, open ground like a cage-top playground. A large aviary also allows them flee any territorial attackers. In a closed cage, however, the risk of injury is a lot more real.
Did you know? Cockatiel cages are often unsuitable for budgies. The bars tend to be spaced too far apart, causing an escape risk or making it possible for your budgie to get themselves stuck.
Are there exceptions?
As mentioned, indoor cages are more of a problem than large, outdoor aviaries. Cockatiels and budgies are kept together by aviary owners all the time, but I still want to mention that it's not my favorite option.
Territorial budgies can become violent if they've got their sights set on a specific nesting box. This can cause injuries and dead chicks if there were already cockatiels nesting in the box.
In short: it can be done, but I wouldn't. If you want to add some extra life to a cockatiel or budgie aviary, why not consider small quail like the genus Coturnix? Because quail stick to the bottom of the enclosure, they're usually simply ignored, which is perfect for peaceful co-existence.
Should I get a budgie or a cockatiel?
As the two species can't be kept together, you'll have to choose, unless you're okay with setting up two separate cages.
Not sure whether a budgie or a cockatiel is the perfect feathered companion for you? That's not surprising, both can make great pets and have many wonderful qualities. Which matches you best depends mostly on what you're looking for in your pet, although of course, there are no guarantees as to how individual birds' personalities turn out.
Want to know more? The article on budgie vs cockatiel can help you make an informed decision.
Frequently asked questions
Yes, the two would eat similar things in the wild. The only issue would be if the cockatiel food is on the large side for the budgie, but it should usually manage.
They might try, but as they belong to different species, the two will never be able to produce offspring.

Passive acoustic monitoring can be used for many purposes including biodiversity and habitat assessments and studying the ecology of populations, communities and soundscapes. As such, acoustic recording devices are essential data collection tools for bioacousticians and soundscape ecologists. Currently available commercial options are typically expensive and limited to recording either ultrasonic or audible frequencies. Here, we present the AURITA (Audible and Ultrasonic Recording In TAndem) for the autonomous collection of both audible and ultrasonic acoustic data. This self-contained, modular unit combines the Solo, an open-source, Raspberry-Pi-based recorder and a commercially available bat recorder, the Peersonic RPA2, enabling it to capture sounds from 60 Hz to 192 kHz in WAV format. The configuration presented costs ~£350 (excluding memory cards and batteries) to produce and can be maintained and repaired in the field. Two nine-week field tests involving 12 AURITA units were conducted in 2016 and 2017 and confirmed their reliability, resulting in 34,093 h of audible data and 551 h of ultrasonic data; all units were retrieved successfully and intact. The AURITA proved to be reliable in the field and produced high-quality acoustic data, making it ideal for simultaneous monitoring in both audible and ultrasonic frequencies over continuous periods of time.

Librados - expose checksums¶
Allow librados write operations to pass checksum metadata long with data buffers so that this information can follow the data all the way down the stack for verification at various layers. This will close one of several gaps in providing true end-to-end data integrity verification.
- Sage Weil (Red Hat)
- Name (Affiliation)
- Name (Affiliation)
We checksum data as it passes over the wire, and verify it on the other end (to detect network bit flips that TCP's checksumming misses).
We periodically read data off disk, calculate a new checksum, and compare it to replicas (to detect bit rot).
We use crc32c throughout.
Detailed Description¶We should define a generic, extensible way to describe the checksum of a buffer or data extent. We use crc32c today, but we should avoid locking ourselves into a single scheme for all time.
We should make new write call variants (e.g., rados_write2, rados_write_full2, etc.) that optionally accept checksum metdata for the data buffer being passed in. Same goes for the read operations (we should pass out the checksum metdata along with the data).
Initially, these will not do much.
Eventually, we can extend the internal protocol (the messenger on-wire protocol and/or the rados MOSDOp[Reply] encodings) to pass this data over the wire to the OSD and back.
In some cases, we can use it to populate the checksum fields in object_info_t (see other blueprint).
We can have options to control which layers of the stack recalculate the checksum over the current data buffer for verification against the provided checksum. We probably do not want to do this at every layer (too expensive), but should do it at least once before writing the data to disk, ideally at a point that avoids propagating a bit flip to multiple replicas.
Other things we might do with this later:
- pass checksum info through the ObjectStore interface
- add a rados class (or native rados op) to calculate/verify checksum info on the server side ("fixity check")
- define extensible checksum metadata structure
- define new librados read/write calls that include option checksum metadata (C and C++ interfaces)
- extend MOSDOp and MOSDOpReply to pass checksum metadata for the data payload
- allow this metadata, when present, to allow the messenger to skip the crc it is doing for the data payload


another if statement, but it also incorporates the previous if statement. This isn't crucial here, but it'd be important if, for example, you had one if statement looking for "anything less than 10" and another looking for "anything greater than 5." The values 5 through 9 would trigger both if statements, which could be a problem if they have conflicting actions. Here, else if is saying "if the previous if statement wasn't met, check if x equals 5." Finally, the else tells R that if neither of the previous if statements were met, follow this action.
In point #2, we use x == 5 because that notation asks R if the statement is true or false. If we wrote x = 5, we'd be assigning the value 5 to x, which causes an error within the if statement. You can use the logical operators <, >, <=, >=, ==, |, &, and ! to ask R if a statement is true.
 x == 4 # "x equals 4, true or false?"
 x != 4 # "x does not equal 4, true or false?"
 x > mega.multiply(10, 4) # "x is greater than the output of this function, true or
 # false?"
 x < 4 | x > 2 # "x is less than 4 OR x is greater than 2, true or false?"
 x < 4 & x > 2 # "x is less than 4 AND x is greater than 2, true or
 # false?"
__________________________________________________________________
Integrating function, if, and for loops
In the previous blog post, we talked about for loops and random walks. Much like a frustrating cumulative exam in school, let's incorporate everything we've learned to answer a tougher question: how do we write a function that finds the median?
No, using R's built-in median function won't cut it in this tutorial. Let's write our own. (median does, however, serve as a nice check to see whether our function is doing what we think it is.)
As a brief review of summary statistics, when we have a set of numbers, we often want a description of the "average" value of the set, or what we would expect if we drew a random value. Common descriptors are the mean, median, and mode. The median is the value that divides the set such that half of the values are below the median, and half are above. The median doesn't care about the actual values in the set; it will just find the middle-ranked one. It's therefore insensitive to outliers that would otherwise wreck the output from the mean. (If Bill Gates was visiting a high school classroom, the mean income of the people in the classroom would be millions of dollars, while the median would correctly be closer to zero.)
There are a few steps to finding the median. Let's write them here to clarify the plan of attack. We start with a set of values. Then:
1 - Sort the values from lowest to highest

2a - If there are an odd number of values, the middle value (where half the values lie below this point and half the values lie above) is the median
2b - If there are an even number of values, find the middle two values. Take their mean. This value is the median.
This is how the above would look like in R:
 med <- function(x){
 if(length(x) %% 2 == 1){ # "If the number of values is odd"
 return(sort(x)[length(x) / 2 + 1/2]) }
 if(length(x) %% 2 == 0){ # "If the number of values is even"
 return(mean(sort(x)[c(length(x) / 2, length(x) / 2 + 1)])) }
 }
 A more detailed explanation:
 med <- function(x){ # med will be a function that takes one input
 # Number of values is odd
 if(length(x) %% 2 == 1){ # If the length of the input, divided by 2, leaves a
 # remainder of 1
 return( # Return whatever will result from inside these
 # parentheses
 sort(x)[ # Sort the values of x from lowest to highest and
 # find the value that...
 length(x)/2 + 1/2])} # ...is 1/2 + the length of the input divided by 2 (i.e.
 # the middle)
 # Number of values is even
 if(length(x) %% 2 == 0){ # If the length of the input, divided by 2, leaves a
 # remainder of 0
 return(mean( # Return the mean of...
 sort(x)[c(length(x) / 2, # ...the sorted values of x, specifically the
 # "low" middle value...
 length(x)/2 + 1)]))} #... and the "high" middle value
Combining all that with a for loop
Nice work! Finally, let's create a one-dimensional random walk that uses if statements and our median function. Let's say we want to impose boundaries on our random walk such that if it wanders too far from the origin, we restart it at the median of the walk so far.
 # Set the parameters
 n.steps <- 1e5 # 100,000 steps (1.0 x 10^5)
 mean.step <- 0 # The random walk is unbiased (no preference up or
 # down)
 sd.step <-0.5 # The standard deviation of step sizes (steps are drawn
 # from a normal distribution)
 up.boundary <- 50 # The upper boundary of our walk
 down.boundary <- -50 # The lower boundary
 # Prepare variables
 walk <- 0 # Start the walk at zero
 shifts <- c() # Create an empty variable to note when the walk hits
 # boundary
 # The random walk
 for(i in 2:n.steps){
 # First, take a step
 walk[i] <- walk[i-1] + rnorm(1, mean.step, sd.step)
 # If the walk went above the upper boundary or below the lower boundary...
 if(walk[i] > up.boundary | walk[i] < down.boundary){
 walk[i] <- med(walk) # The walk resets at the median value of the
 # walk up to this point
 shifts[i] <- i # We also note the step at which this occurred
 }
 print(i) # Tell us what iteration of the walk we're on
 }
 # Plot it
 plot(walk, type = 'l', main = "A supervised random walk", las = 1, xlab =
 "Time", ylab = "Position", cex.main = 1.8, cex.lab = 1.4, font.lab = 2, col =
 "gray40")
 abline(v = shifts, col = "blue")
 par(font = 2)
 legend("topleft", lty = 1, col = "blue", legend = "Shifts", cex = 0.8)
Thanks for reading. In the next post, we'll cover the apply functions, which are very powerful methods for performing many calculations at once and efficiently analyzing matrices and data frames.

How to Create a QR Code for Vaccination? See how Digital Health Passports are Using Vaccine QR Codes!
Create QR Code for Vaccine
✅ Learn how to make a QR Code for vaccination. ✅ Why is the healthcare industry is using a QR Code generator to track vaccination and and digital passports?
Trusted by top brands
As vaccines are becoming more and more available, people are looking for ways to help speed up the vaccination process. Vaccine QR Codes are here to help – they help governments keep track of vaccines, give people a digital passport for vaccination, and much more!
Many companies are already taking advantage of this technology and spreading the good help digitally. Many of us may wonder though – What is a vaccine QR Code and how do I use it?
PRO Tip: You can easily create a QR Code for vaccines here!
Vaccine QR Code Generator
You can use a QR Code Generator to help people book vaccination appointments.
What is a vaccination QR Code?
QR Codes for vaccines are mostly like ordinary QR Codes. They have been customized to fit the vaccination vials, product packaging, or other informational materials to digitalize the physical goods. Many governments have already approved the usage of vaccination QR Codes to help track the vaccine supply and to verify the goods for shipping.
It doesn't just stop there though. The use case for QR Codes is much larger than just product packages and vaccine labels. You can create QR Codes for all kinds of informational materials to help spread the availability and knowledge related to stopping the pandemic crisis:
Long story short – a vaccine QR Code is a code created by a QR Code Generator tool and related to helping spread information and availability about vaccines.
Watch as CNBC experts discuss COVID-19 Health passports and how to use QR Codes
What is a vaccination passport QR Code?
Mainly, Vaccination passport QR Codes are digital passports that can be used for different countries, companies, and locations. This helps to verify if a person is already vaccinated and helps keep the risk of contamination low.
Secondly, People use vaccine passport QR Codes for traveling and verifying thier health status without revealing any sensitive data or information.
Many apps use QR Codes to help with digital health certificates and vaccination. Have a vaccination or Covid-19 related app? Learn how to create an app QR Code to help more people download your app easily.
Why are QR Codes used for vaccines?
PRO Tip: Did you know that using QR Codes also helps maintain social distancing?
#1 Vaccination passports and digital health certificates
Think of it as your vaccination passport, but a more modern and digital version of it. Creating QR Codes help medical institutions track patients history and health status quickly and without any errors.
#2 Vaccine packaging and vial product labels
It is strongly recommended to use QR Codes on the vaccine packaging by the WHO. This is because it can instantly show digital versions of any information and provide additional info that may not be printed on a small vial or package label.
Vaccination QR Codes are the preferred method over traditional printing to distribute information because it can always be updated later when needed and some new info or news has appeared.
#3 Tracking shipments of vaccines
QR Codes for vaccines can help supply chains and inventory management. Warehouses can scan them to keep track of their stock and inventory. It also quickly shows the contents of packages without having to open any boxes for inspection or to read the shipment manifest papers.
#4 Promoting vaccination safety and knowledge
The CDC has created vaccine information statements (VIS) to help providers share important information about their vaccine products. These materials are otherwise difficult to navigate, but using QR Codes for vaccination products simplifies this process a lot.
People can easily get more info when they scan the code to get the VIS data and record the EMR (an electronic medical record) on their smartphones and devices.
#5 Giving people easy access to vaccines
People are able to book doctor's appointments with vaccine QR Codes. Secondly, they can also get quick access to approved sources for the latest news and information about the release status of vaccine products near their location.
How to use a QR Code for vaccination
Want to help? Using Donation QR Codes make it easy to help spread the vaccine in the world.
How are QR Codes used for vaccination?
For instance, many countries have already established digital health certificates that use QR Codes. This restricts access in and out of the country for travel.
It's not only the countries' borders that are using QR Codes. Many cafes, restaurants, and establishments are using a Covid-19 declaration form to scan all their visitors to help contain the spread of the pandemic. This creates more time for vaccines to arrive and be distributed.
If you're looking to make QR Codes for vaccines, then we can suggest you look into QR Code Generators. It's really easy to use and takes only a few minutes to create one.
Are QR Codes good for vaccination?
In addition to travel and safety, QR Codes can be used for donations and charity. Many people are in need of vaccines who aren't able to afford them. Governments can only support their people to a certain limit and older age groups will have a priority in line.
Try using a Donation QR Code to do some good.
QR Codes can offer information in any language, depending on who is scanning the code. They are economical and easy to access – it's easily available to anyone with a smartphone. This makes it the main preferred tool to share and access information about everything related to the vaccine.
Finally, vaccines are arriving and helping to restore our economy back to normal. We can use Vaccination QR Codes to make it easier for both people and authorities to share and access information. Many nations prefer QR codes to track their health status and distribute vaccines easily.

What Is The Definition Of An Hypothecation Agreement
The investment hypothesis arises when a trader or investor promises guarantees for a margin-to-purchase credit or short securities. In particular, brokers/traders (BDs) offer marginal accounts that allow traders to borrow up to 50% of the value of securities. The margina account agreement contains a mortgage agreement for guarantees. As a general rule, the former and the second holders of pledges draw up an agreement on how to handle this unfortunate event. If you are interested, you can read this real example of hypothesis agreement. Rehypothecation is more common when it comes to stocks, as a broker will use collateral stocks to secure their own trades. In the past, this rate was more frequent, but popularity declined after the 2008 and 2009 recession. In the United Kingdom, there is no limit to the amount of a client's assets that can be rehypothecated[3] unless the client has negotiated an agreement with his broker that includes a limit or prohibition. In the United States, re-mortgage is limited to 140% of a customer's balance. [4] [6] The following language is for a form for a real estate mortgage contract and comes from Law Insider: As a pledge, you intend to transfer the asset to another owner.
If not, your intention is to secure the asset to secure a loan. What is important is that you plan to keep the security on the hypothetical asset after you have repaid the loan. "We believe that the assumption agreement signed by Ms. Lauver was sufficient to demonstrate that the bank held a contractual pledge in the account represented by the CD. The hypothesis agreement makes it clear that it is intended to guarantee Mr Cummins' debt to the bank, and the specific security is described. We are not informed that Ms. Lauver was incompetent, deceived or involved under inappropriate influence when the hypothesis agreement was signed. We believe that her intention is under-interpreted by the mortgage agreement, in which she clearly granted the bank a contractual guarantee over the proceeds of her bank account at the Federal Capitol.
The right to pledge that it created is certainly valid and before any interest that its executor may have acquired on the proceeds of the bank account. A hypothesis agreement may stipulate that a tenant cannot submit his interest to a rental agreement or premises without the landlord's consent. The following example shows this type of hypothesis agreement. In 2007, re-mortgages accounted for half of the activities of the shadow banking system. Because security is not cash, it is not displayed in traditional accounting. Before Lehman's collapse, the International Monetary Fund (IMF) calculated that U.S. banks received more than $4 trillion through the re-library, much of which comes from the United Kingdom, where there are no legal limits on the reuse of a customer's guarantees. It is estimated that only a trillion dollars of initial security have been used, meaning that security has been re-hepthetized several times with an estimated emigration factor of 4. [5] Hypothecation Letter is another name for a mortgage agreement.

Northern Region Small Towns Water and Sanitation Project (NORST)
Sub-Saharan Africa — Ghana
Client: Department of Foreign Affairs, Trade and Development
CowaterSogema is implementing this seven-year project which will provide increased access to potable water and sanitation services in up to 30 selected small towns in the Northern Region of Ghana (approximately 125,000 beneficiaries) through design, installation, and capacity building support for the operation of water supply systems and appropriate sanitation facilities. The project will also provide socio-economic improvement by strengthening local capacity to manage and sustain access to potable water and sanitation services in small towns. Upon completion of the work, the project will have: a) increased the capacity of stakeholders at regional, district and sub-district levels to effectively fulfill their respective roles in the delivery of potable water and sanitation services; and b) constructed water supply and sanitation installations that adequately supply communities. The NORST project will support the implementation of project activities by the authorities and agencies responsible for the delivery of water and sanitation services to small towns in Ghana.


History Puzzles
Silvija Staff Image
NLS acquires audio and braille titles in many foreign languages from various domestic and foreign producers, as well as from cooperating agencies serving people who cannot read standard print around the world.
Using the Voyager Search interface, the NLS collections may be searched to find talking books in other languages, including French, German, and Russian. Though some languages are represented with only a few titles, the foreign-language collections are constantly growing.
As someone who loves French language and history, I would like to recommend an audio book recorded in the French language with the title Les pourquoi de l'Histoire by Stéphane Bern (DBF99837).
It is a summary of History's "secrets" which allows you to learn new things and broaden your knowledge through 120 questions and answers like:
– Why is the King of Spain French?
– Why is the First World War not the first?
– Why are there several pretenders to the throne of France?
– Why did Francisco Franco receive the Legion of Honor?
– Why was Churchill appointed Prime Minister without ever getting a majority of the British people?
– Why was Cleopatra, Queen of Egypt, not Egyptian?
– Why do Brazilians not speak Spanish, but Portuguese?
– Why did Bonaparte launch an expedition to Egypt?
– Why can we say that the FBI was founded by a Bonaparte?
– Why was Jesus not born in year 0?
– Why in 1582, did we calculate a single night between December 9th and December 20th?
You will enjoy all the history puzzles and exciting new facts while practicing French!

PHYSICAL ACTIVITY, PHYSICAL CAPACITY AND SELF-RATED HEALTH IN ELDERLY WOMEN
Jurgita Naujokaitė, Miglė Bacevičienė, Sandra Kilikevičienė, Vida Janina Česnaitienė Lithuanian Sports University, Kaunas
Purpose of the research – to assess the relations between physical activity, physical capacity and self-rated health in elderly women.
Research methods. The study was carried out in Lithuanian Sports University in 2016–2017. Twentythree volunteers physically active women from Kaunas city were involved in the study. The average age of the study participants was 66.0 ± 8.1 years. All the participants were free from any chronic cardiovascular, respiratory and muscle-bone-joints disease. All study participants filled in the questionnaire to determine the level of physical activity and performed tests to assess physical capacity. Aerobic capacity was assessed using 2-minute walk test. Hand static muscle strength was determined by dynamometry and body balance test was performed counting the times of body balance loss during 30 seconds. Anthropometric indicators such as body mass index, ratio of body fat, skin folds and blood pressure were measured. Objectification of physical activity was performed by accelerometry method. Accelerometer was placed on the waist and one week's physical activity was assessed recording the number of steps and energy expenditures. Statistical analysis was performed using Microsoft Excel and SPSS statistical software.
Results. The average of steps made during 1 week was 54,078.5 ± 17,625.7. Mean energy expenditures during 1 week was also sufficient (2916.4 ± 880.2 kcal and 2289 ± 775.1 METs). Physical activity score assessed by questionnaire method was 5.0 ± 1.2. Very strong statistical correlation was found between steps maid during 1 week and energy expenditures measured in kcals and METs (r =.9). Also strong statistical correlation was detected between body mass index and body fat (r =.9). Inverse statistically significant correlation was detected between body mass index and number of steps maid during 1 week (r = -.7). No significant correlations were found between physical activity and physical capacity indicators. Higher physical activity was correlated with better self-rated health (r =.6). Better aerobic physical capacity was significantly associated with higher muscle strength, better body balance and with higher blood pressure and higher rest heart rate.
Conclusion. Physical activity had positive impact on older women's body composition whereas better aerobic physical capacity was associated with higher muscle strength and higher blood pressure.

Researchers have reached a significant milestone in the field of quantum gravity research, finding preliminary statistical support for quantum gravity.
In a study published in Nature Astronomy on June 12, a team of researchers from the University of Naples "Federico II," the University of Wroclaw, and the University of Bergen examined a quantum-gravity model of particle propagation in which the speed of ultrarelativistic particles decreases with rising energy. This effect is expected to be extremely small, proportional to the ratio between particle energy and the Planck scale, but when observing very distant astrophysical sources, it can accumulate to observable levels. The investigation used gamma-ray bursts observed by the Fermi telescope and ultra-high-energy neutrinos detected by the IceCube Neutrino Observatory, testing the hypothesis that some neutrinos and some gamma-ray bursts might have a common origin but are observed at different times as a result of the energy-dependent reduction in speed.
"By combining data from IceCube and Fermi, we found preliminary evidence supporting quantum gravity models that predict this effect. This marks a significant milestone in the field of quantum gravity research since it is the first time that such a level of quantum gravity-supportive statistical evidence is found," says corresponding author, Professor Giovanni Amelino-Camelia of the University of Naples on behalf of the team.
"While these findings are preliminary, they provide a strong foundation for further detailed investigations as we continue to gather data from our gamma-ray and neutrino telescopes. Even if future data were not to confirm this effect, our findings would still provide stringent limits on the parameters of relevant models, which would already represent a rare and notable step for quantum gravity research," adds Amelino-Camelia.

|Syntactic Confectionery Delight|
Re: Counter - number of tags per intervalby LanX (Chancellor)
|on May 04, 2013 at 22:08 UTC||Need Help??|
Just another idea based on tuning your current algorithm which is quite clever! (Well after being understood - you know my opinion about clear naming ;-)
After analyzing the numbers you provided, I suppose that intersections of different ranges are comparatively rare and if they appear they stretch over long distances.
So it doesn't really make sense to go into the count loop for each individual point, just go on counting the "1" till you reach the next "boundary" and add them collectively to your counter instead incrementing them one by one with++.
The boundaries are nothing else as the sorted list of range starts-1 and stops. In your example for ID "b"
this means [9,11,15].
and results in the following flow
As you see, you can also stop counting between ranges and even try to jump forward in the file with seek.
3e6 Intervals/50 IDs *2 Borders = 120000 Borders
6e9 Points / ID
=> in average 6e9/12e4=50000 points between two adjacent borders, where you can avoid the whole count loop.
This should lead to a considerable boost!

Why is My Light Switch Hot?
If one or more of the light switches in your home are warm or hot to the touch, it's usually a sign there's too much electrical power running through it. There are several reasons why this happens.
When a Light Switch Feels Warm
One of the most common electrical questions we get asked is if it's normal for a light switch to feel warm.
It's perfectly normal for light switches, particularly dimmers, to feel a little warm when the lights are on. The warmth you feel comes from an electrical component called the triac (triode for alternating current) which varies the amount of electricity that passes through to the light fixture. If the dimmer switch is dedicated to a single bulb, or a load of 100 watts or so, you might feel a little heat. Once the load gets above 300 watts, though, it's not unusual for the heat to be more noticeable.
When a Light Switch is Hot
If a light switch is too hot to touch, it's likely a more serious problem. The top three reasons this happens are:
 - The switch is overloaded. Just like wall outlets, light switches are limited in how much power they can handle. Different switches are rated for different power levels and if the switch is overloaded there's a serious risk of fire. The switch should be replaced with one that's designed to handle the amps a fixture requires.
 - The switch is failing. Light switches wear out and when this happens small sparks on the electrical contacts are emitted when the light is turned on or off. Over time, the contacts don't meet properly and electricity flows more freely, creating heat. This, too, is a fire hazard.
 - Faulty or improper wire installation. Even if the wiring was professionally installed, it can become loose or broken due to age. These bad connections can then cause the wiring to spark and generate heat. They can also bottleneck the current flow, which also gives off heat. Faulty wiring should always be replaced by an experienced, licensed electrician.
When to Call For Help
There are electrical problems you can usually fix yourself but, as electrical work can be dangerous, it's almost always recommended to call in a professional. Along with a hot light switch, it's a good idea to call in the pros if:
 - The lights dim when using a major appliance or when the HVAC unit goes on.
 - One socket of an electrical outlet's not working.
 - A light switch doesn't solidly connect in the on or off position.
 - You have an old "fuse" system in your home.
A qualified electrician will also check to make sure your home's electrical panel is able to safely handle powering everything in your home.
Hot light switches in your Jacksonville home can usually be easily and quickly fixed, but you should never ignore the problem as it could indicate a bigger electrical issue.
