It was invented by Christiaan Huygens in the late 1660s and was the first compound (multi-lens) eyepiece. Huygens discovered that two air spaced lenses can be used to make an eyepiece with zero transverse chromatic aberration. Since these eyepieces are cheap to make they can often be found on inexpensive telescopes and microscopes. Because Huygens eyepieces do not contain cement to hold the lens elements, telescope users sometimes use these eyepieces in the role of "solar projection", i.e. projecting an image of the Sun onto a screen. Other cemented eyepieces can be damaged by the intense, concentrated light of the Sun.
The DVD optical disc storage format was invented and developed by Philips and Sony in 1995. In the early 1970s, Philips' researchers started experiments with "audio-only" optical discs, and at the end of the 1970s, Philips, Sony, and other companies presented prototypes of digital audio discs. While making a coloured liquid for a thermometer, Cornelis Drebbel dropped a flask of Aqua regia on a tin window sill, and discovered that stannous chloride makes the color of carmine much brighter and more durable.

The Dutch roll was the first form of a gliding or skating motion made possible by the iron skate's two edges. However, speed skating was the focus of the Dutch, while the English developed modern figure skating. The Permanent Court of Arbitration is an international organization based in The Hague in the Netherlands.
These still lifes usually depict one or more especially precious objects. Although the term is a post-17th century invention, this type is characteristic of the second half of the seventeenth century. It was developed in the 1640s in Antwerp from where it spread quickly to the Dutch Republic. De Heem, who spent a long period of his active career in Antwerp and was one of the founders of the style in Holland.

For example, coagulation disorders can cause prenatal or perinatal strokes that damage the brain and produce symptoms characteristic of CP, most commonly hemiparetic CP. Referrals to specialists such as a child neurologist, developmental pediatrician, ophthalmologist, or otologist aid in a more accurate diagnosis and help doctors develop a specific treatment plan. Cranial ultrasounduses high-frequency sound waves to produce pictures of the brains of young babies. Doctors will order a series of tests to evaluate the child’s motor skills. If a child is continuously losing motor skills, the problem more likely is a condition other than CP—such as a genetic or muscle disease, metabolism disorder, or tumors in the nervous system. Most children with cerebral palsy are diagnosed during the first 2 years of life.
The cord could also slip around the baby’s neck or arms, causing injury. Different healthcare providers have various levels of comfort with vaginal deliveries of breech babies. Talk to your provider about the risks and benefits of different types of birth for a breech baby. Learning that the fetus is in a breech or other complicated position before birth can add to the anxiety that often surrounds childbirth. It’s alright to have concerns and questions about what this means for your birth experience. Take your birth plan to an appointment and talk to your healthcare provider about what you are picturing for your labor and delivery.

Contracture— a condition in which muscles become fixed in a rigid, abnormal position, which causes distortion or deformity. Choreoathetoid— a condition characterized by aimless muscle movements and involuntary motions. Study will lead to an innovative clinical therapy aimed at improving locomotor function in children with CP.
Your gut is telling you that your baby isn’t where he should be. To do this move, you’ll carefully kneel at the end of a couch or low bed. Then slowly lower your hands to the floor below and rest on your forearms.
Seizure disorder.As many as half of all children with CP have one or more seizures. Children with both cerebral palsy and epilepsy are more likely to have intellectual disability. CP is the leading cause of childhood disabilities, but it doesn’t always cause profound disabilities. While one child with severe CP might be unable to walk and need extensive, lifelong care, another child with mild CP might be only slightly awkward and require no special assistance. The disorder isn’t progressive, meaning it doesn’t get worse over time. However, as the child gets older, certain symptoms may become more or less evident.
As well as these licensed options, parents may also choose to find their own caregiver or arrange childcare exchanges/swaps with another family. You are doing the best you can with a suddenly complex situation. Together you will find your way to the other side of the transverse lie. The baby will stay transverse when the pelvic inlet is not symmetrical or the lower uterine segment is not symmetrical. Crossing our legs, holding toddlers on our favorite hip, a fall, etc. can put a twist in the lower uterine segment.
So, if moms want to get that little bean moving around, they can place a cool, wet wash cloth on their stomach. They should not feel like they are torturing their babies by placing something cold on their stomach, as it does not cause them any pain or discomfort. It is just a change in an environment to stir them to attention.
VBAC. I was told yesterday that my baby is currently transverse and I am very concerned that I will not be able to have another VBAC due to this…. Acupuncture, effective for fetal positioning, especially when done by an experienced professional. Most women need specific balancing exercises to bring a twist out of their lower uterine segment. Body work is recommended if you can get good care where you live. A gentle stretch of the psoas can be done with you lying on your bed with your hips on the very edge.
Your provider will look at your medical history, the scans of your baby throughout your pregnancy and the position of the fetus to pick the safest form of delivery. When the fetus is in a breech position or another abnormal position, your healthcare provider may suggest a cesarean section (C-section) delivery. This is a surgical procedure where an incision is made in your lower abdomen.
A Leyden jar, or Leiden jar, is a device that "stores" static electricity between two electrodes on the inside and outside of a glass jar. It was the original form of a capacitor (originally known as a "condenser"). It was invented independently by German cleric Ewald Georg von Kleist on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek of Leiden in 1745–1746. The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electricity. Previously, researchers had to resort to insulated conductors of large dimensions to store a charge.
