Termite

termite (order Isoptera), any of a group of cellulose-eating insects, the social system of which shows remarkable parallels with those of ants and bees, although it has evolved independently. Even though termites are not closely related to ants, they are sometimes referred to as white ants. Phylogenetic studies have shown that the closest relative to the termite is the cockroach; for this reason termites are sometimes placed in the order Dictyoptera, which also contains the mantids.

Termites are insects that eat wood. They can damage buildings, furniture, and other wooden items. There are more than 1,500 species, or kinds, of termites. They are most common in tropical rainforests.

Although they are closely related to cockroaches, termites are sometimes called “white ants” because their general appearance and social organization are like those of the ants. Termites, however, are distinguished from ants by their soft bodies and lighter color. Ants have hard bodies and are usually dark (see Ant). Furthermore, the termite’s midbody segment, or thorax, is broadly attached to the rear segment, or abdomen, whereas ants have a constriction where the thorax joins the abdomen. Termites belong to the insect order Isoptera.

How to Recognize Fetal Alcohol Syndrome: 10 Steps (with Pictures) #fetal #alcohol

How to Recognize Fetal Alcohol Syndrome

Consuming alcohol during pregnancy can severely harm a developing fetus and may have lasting health and developmental consequences known as Fetal Alcohol Spectrum Disorders (FASDs). [1] One of the most distressing disorders caused by alcohol consumption during pregnancy is Fetal Alcohol Syndrome (FAS). It is a lifelong condition and yet one of the most preventable causes of birth defects and intellectual disability. If you notice any symptoms of FAS, see your child’s doctor as soon as possible to help formulate a treatment plan that may alleviate symptoms.

Steps Edit

Part One of Two:
Recognizing the Symptoms of Fetal Alcohol Syndrome Edit

Be aware of your child’s risk for FAS. The exact cause of FAS is alcohol consumption. The more you drink while pregnant, especially during the first trimester, the greater the risk of your unborn fetus developing FAS. [2] Being aware of your child’s risk for this disease can help you recognize it and get a diagnosis and treatment in a timely manner.

  • Alcohol reaches the developing fetus through the placenta and causes higher blood alcohol concentration levels in a fetus than in you. A fetus metabolizes alcohol at a much slower rate. [3]
  • Alcohol interferes with oxygenation and nutrition delivery to your unborn baby. This can severely impact the fetus’s developing tissues and organs, including the brain. [4]
  • You may have consumed a lot of alcohol before you realized you were pregnant, putting your unborn baby at risk for FAS. [5] Keep this in mind during and after your pregnancy. [6]

Recognize physical symptoms of FAS. There are many different physical symptoms of FAS that may be mild or severe. From distinctive facial features to slow growth patterns, identifying these common markers may help get your child a diagnosis and medical treatment.

  • Symptoms can appear while the baby is still developing in utero or at birth. They may also only present later, such as behavior issues. [7]
  • Facial features such as wide-set eyes; an extremely thin upper lip; a short, upturned nose; and lack of lip folds between the nose and upper lip may indicate FAS. [8] A child with FAS may also have narrow and small eyes. [9]
  • Deformed joint and limbs may indicate FAS. [10]
  • Slow growth patterns both before and after birth may indicate FAS. [11]
  • Vision and hearing issues may indicate FAS. [12]
  • Small head circumference and underdeveloped brain may indicate FAS. [13]
  • Heart defects and issues with kidneys may also indicate FAS. [14]
  • Many symptoms of FAS resemble those of other diseases and conditions. If you suspect your child or another might have FAS, it’s important to see a doctor and/ or get a second medical opinion.

Observe brain and central nervous symptoms. FAS may also present itself as problems with a child’s brain and central nervous system. From poor memory and hyperactivity, observing these common neurological symptoms may help you identify FAS and get your child a diagnosis and medical treatment.

  • Children with FAS may have poor coordination and balance. [15]
  • Children with FAS may have intellectual disabilities, learning disorders, poor memory, trouble with paying attention, or hyperactivity. [16]
  • Children with FAS may have trouble processing information, reasoning, and poor judgment skills. [17]
  • Children with FAS may also have rapidly changing moods or anxiety. [18]

Notice social and behavior issues. Fetal Alcohol Syndrome can also manifest itself in social and behavioral issues. From poor social skills to problems with impulse control, noticing these behavioral markers may help you identify FAS and get your child a diagnosis and medical treatment.

  • Poor social skills including getting along with others may indicate FAS. [19]
  • A child with FAS may have difficulty in school or problems staying on task or working towards a goal. [20]
  • A child with FAS may have problems adapting to change or with impulse control. [21]
  • A child with FAS may have a poor concept of time. [22]

Metallic bond

metallic bond, force that holds atoms together in a metallic substance. Such a solid consists of closely packed atoms. In most cases, the outermost electron shell of each of the metal atoms overlaps with a large number of neighbouring atoms. As a consequence, the valence electrons continually move from one atom to another and are not associated with any specific pair of atoms. In short, the valence electrons in metals, unlike those in covalently bonded substances, are nonlocalized, capable of wandering relatively freely throughout the entire crystal. The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.

Many of the characteristic properties of metals are attributable to the non-localized or free-electron character of the valence electrons. This condition, for example, is responsible for the high electrical conductivity of metals. The valence electrons are always free to move when an electrical field is applied. The presence of the mobile valence electrons, as well as the nondirectionality of the binding force between metal ions, account for the malleability and ductility of most metals. When a metal is shaped or drawn, it does not fracture, because the ions in its crystal structure are quite easily displaced with respect to one another. Moreover, the nonlocalized valence electrons act as a buffer between the ions of like charge and thereby prevent them from coming together and generating strong repulsive forces that can cause the crystal to fracture.

Can I Use Shopping Cart Creator on an Existing Website? #free #html


#

Shopping Cart Creator generates all the files you need to run your online shop, which means it can be used as a standalone website. Additionally, the Pages Tool gives you the option to add up to five custom webpages to your store. These can be used as a shop homepage, a FAQ, a refund policy page, etc.

However, if you already have a preexisting website, you can easily incorporate your online shop. This is a two-step process:

Step 1: Uploading Your Shop

When you upload your shop, you re going to need to tweak your normal FTP settings slightly. This is because you want to upload your shop to its very own sub-folder. You get to name this sub-folder whatever you want we recommend using a name like shop or store, but it s up to you.

How do you create this folder? Well, that depends on your hosting provider, as well as your remote folder. The most common way to create your shop s sub-folder is to append your remote folder with /subfoldername. Subfoldername is the name of the sub-folder where you want your shop to be stored. Here are a few examples:

If you re still unsure of what exactly to put in these fields, or if you ve tried these options and your shop still isn t uploading correctly, contact your hosting provider. Ask them what you should do to upload your files to a sub-folder.

Step 2: Integrating Your Shop

The first step can sometimes be a little tricky, but you ll be happy to learn that the second step is as easy as creating a link on your webpage. If you re using an HTML editor such as CoffeeCup HTML Editor or the code editor in CoffeeCup Direct FTP, you ll use this HTML:

a href= Shop URL Text you want to appear as a link /a

  • Shop URL is the URL for your shop. You can use a relative or absolute link. For more information about relative versus absolute linking, read this article: Absolute vs. Relative Paths/Links .
  • Text you want to appear as a link is the linked text your visitors will click on. Read this article in the preceding paragraph is linked text.

If you re using Visual Site Designer. create and highlight the text or object you want to make into a link, and then click the Link button in the Toolbar. Check the Use Link checkbox. make sure the WWW radio button is selected, and enter the URL for your shop in the WWW field .

If you re using menu-building software, such as Menu Builder. you can create a new menu button and link it to the URL for your shop.

Unsure of how to determine the URL for your shop? No worries, it s not that hard! If you appended the name of your remote folder with the name of your shop sub-folder, it s as simple as http://www.yourdomain.com/subfoldername. Here are a few examples:

  • http://www.mywebsite.com/shop
  • http://www.mysite.com/store
  • http://www.mydomain.com/webshop

If you contacted your hosting provider and they gave you a super-complicated method of adding a subfolder, you might want to ask them how to easily find your shop URL.
