Hyperpolarized carbon-13 MRI is a functional medical imaging technique for probing perfusion and metabolism using injected substrates.. It is enabled by techniques for hyperpolarization of carbon-13-containing molecules using dynamic nuclear polarization and rapid dissolution to create an injectable solution.
Hyperpolarization machines are currently being used to develop hyperpolarized xenon gas that is used as a visualization agent for the lungs. Xenon-129 is a safe inert noble gas that can be used to quantify lung function. With a single 10-second breath hold, hyperpolarized Xenon-129 is used with MRI to enable 3-dimensional lung imaging.

The hyperpolarization creates a large signal intensity, and the wide range of chemical shifts allows for identifying when the 129 Xe associates with molecules like hemoglobin. 129 Xe is preferred over 131 Xe for MRI because 129 Xe has spin 1/2 (compared to 3/2 for 131 Xe), a longer T1, and 3.4 times larger gyromagnetic ratio (11.78 MHz/T).

Within the scope of the GÖKÇE Project, ANS/KKS/Laser guided, which can be used with the 1000-lb Mk-83 general purpose bombs in the HvKK inventory and the SARB-83T sequential piercing warhead developed and produced by TÜBİTAK SAGE, has the ability to effectively hit moving and fixed targets. and a cost-effective guidance kit will be developed.
Hyperpolarization is the process of aligning the nuclear spins in a gas, such as 3 He or 129 Xe, in the same direction to create a strong signal for imaging. To accomplish this, angular momentum is added to the system through the use of circularly polarized laser light.
It was established in 1972 at Beşevler neighborhood in central Ankara under the name "Guided Vehicles Technology and Measurement Center" (Güdümlü Araçlar Teknoloji ve Ölçüm Merkezi, GATÖM) by the Scientific and Technological Research Council of Turkey (Turkish: Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK). In 1983 ...
It is intended to be operated in cross-border and residential area. The missiles are launched from 550 mm (22 in) long, single-use tubes. Each missile and its tube together weigh about 0.5 kg (1.1 lb). The mini-missile has a maximum distance of 2 km (1.2 mi) and an effective maximum range of 100–500 m (330–1,640 ft).
[1] The company was founded when Ugur Cooling started ice cream machine production in Nazilli in 1954. Today, the company produces a range of equipment including deep freezers to bottled water coolers , motorcycles, scooters and cosmetics , with the company operating Europe's second-biggest refrigeration plant in Nazilli.
