The TABER Abraser (Abrader) is used to perform accelerated wear testing. Referenced in numerous international standards, materials include plastics, coatings, laminates, leather, paper, ceramics, carpeting, safety glazing, and many others. Simple to operate, the Taber Abraser is capable of providing reliable data in a matter of minutes compared to the years that may be required by in-use testing.

The skull is made up of 22 different bones – 8 cranial bones that enclose your brain within the neurocranium, and 14 facial skeleton bones. There are also 6 ear bones. With the exception of the mandible, the bones of the skull are joined by sutures, which are a kind of joint that is synarthrodial – in other words, it can’t move.
The 8 cranial bones include one occipital bone, one sphenoid bone, one ethmoid bone, one frontal bone, a pair of parietal bones, and a pair of temporal bones. The occipital bone is found at the back of the skull. The sphenoid bone can be found in the middle inferior portion of the neurocranium and kind of looks like a butterfly. It is in front of the temporal bone and is one of 7 bones that articulate to form the orbit. The other six are the frontal bone, the lacrimal bone, the ethmoid bone, the zygomatic bone, the maxillary bone, and the palatine bone.
The ethmoid bone is found between your eyes, located at the roof of the nose, and separates the nasal cavity from the brain. The frontal bone is the bone of your forehead. It has two portions – one vertical, and also the horizontally-oriented orbital portion.
The remaining 4 bones are a pair of parietal bones and a pair of temporal bones. The parietal bones are joined together at the top of the skull. Together, they form the top and sides of the neurocranium. Each bone is roughly quadrilateral in shape. The temporal bones can be found at the sides and base of the skull. They are overlaid by what we call the temples. It is inside the petrous part of the temporal bone that we find the ossicles – the bones of the middle ear and the smallest bones in your body. A set of three ossicles is found on each side of your head, so there are 6 ossicles in total. These bones include the hammer, anvil, and stirrup, also called the malleus, incus, and stapes. The ear canal, which joins the outer and middle ears, is known as the external acoustic meatus. There is also the internal acoustic meatus, which is a tube running from the inner ear to the back of the skull – to what’s called the posterior cranial fossa. We will discuss the three fossa of the skull will be discussed in a later video.
So those were the 8 cranial bones. Again, these included the occipital bone, the sphenoid bone, the ethmoid bone, the frontal bone, a pair of parietal bones, and a pair of temporal bones.
Now for the facial bones. The facial bones include the mandible, the vomer, a pair of maxillae, a pair of palatine bones, a pair of nasal bones, a pair of nasal conchae, a pair of zygomatic bones, and a pair of lacrimal bones.
The mandible is your jawbone. It is the largest bone in the human face and is the only movable bone in the skull apart from the ossicles. The other unpaired facial bone is the vomer, which forms the inferior part of the nasal septum, and articulates with the sphenoid, ethmoid, palatine bones, and maxillary bones. A pair of maxillae are fused together at the intermaxillary suture to form the bone of the upper jaw. This includes the hard palate in the front of your mouth. The two palatine bones, together with the maxillae, comprise the hard palate. They are located at the back of the nasal cavity.
The pair of nasal bones form the bridge of the nose and are joined at the internasal suture. The nasal conchae are thin bony elements forming the upper chambers of the nasal cavities. They are composed of three pairs – the inferior, middle, and superior conchae. The zygomatic bones – or your cheekbones – articulate with the maxilla, temporal bone, sphenoid bone, and frontal bone. The lacrimal bone is a small bone in the front of the medial wall of the orbit.

Corneal eye abrasions can be very painful. Fort Lauderdale ophthalmologist Dr Alan Mendelsohn discusses how the eye recovers and heals from one. Video Rating: / 5
The human body can do some really incredible things. If you think about a typical scrape or a cut, it can go from bleeding to fully healed in less than a month. That’s pretty amazing. However, some conditions can interrupt your body’s natural healing process, resulting in chronic or non-healing wounds.

Social connections
If you talk to someone that has recently moved, started a new job, or retired, and ask them what they miss most about their past situation, one of the most common answers is that they miss the people that were in their life. What that actually means is that they miss the social connections or relationships they had with those people.
Social well being, social connections or social interactions with other individuals is crucial to mental health, which in turn is crucial to overall health. The lack of social connections has shown to increase stress hormones, weaken the immune system, and lessen cardiovascular functions. People who are lonely tend to consume more alcohol, exercise less, have less quality sleep, and fatigue easily.
Social relationships allow you to share your achievements, and have support when times are tough. Imagine achieving a long term goal you had, what is the first thing you want to do, tell someone, share your accomplishment with friends and family of course.
Or imagine if something terrible happened. Not having someone to lean on and talk to, can make that event linger, and make you feel even more isolated.
Giving support in relationships can be more beneficial than receiving support. When someone shares something positive in their life with you, it is a compliment.
They wanted you to be a part of their success, and they know that you have a sincere interest in their life. And when someone shares a tragedy in their life, you know they really trust you, and they are looking to you to help them through this difficult time.
Some social relationships can be bad. A person that is constantly negative and has a poor outlook can bring you down, causing you stress, and negatively affect your mood.
Someone that always talks about themselves, and makes all of your interactions about them, is not really a social connection. In that case you are just an audience member in their one person show on how wonderful their life is.
Poor marital or relationship quality can also weaken the immune system, and erode physical health. Dealing with the stress from a poor relationship can lead to over consuming food or alcohol, smoking, or taking medications to deal with the stress, which in turn can damage systems in the body.
Connections through social media can be beneficial, by allowing you to stay in touch with friends and family at distant locations, however, social media connections are not a good alternative for face to face in person contact.
And too much time spent on social media can lead to more isolation and a greater feeling of loneliness. It is a good practice to use social media in moderation.
To be healthy we need people in our lives, it doesn’t need to be 5000 facebook friends, and we don’t have to have everyone like us. Having strong social relationships with just a few people is fine.
A few people that we can share life’s good and bad moments with, a few people that we can connect with on a regular basis, with no stress, and no judgments, a few people who accept us for who we are.
