Federal University of Minas Gerais Ecological Station. The Federal University of Minas Gerais Ecological Station () is an ecological station in the state of Minas Gerais, Brazil.

Location

The Federal University of Minas Gerais Ecological Station is located on the Pampulha campus of the Federal University of Minas Gerais (UFMG).
It is divided into two areas by Avenida Presidente Carlos Luz.
The first area is bounded by the BR-262 ring road, the Army Ministry CPOR facility, the Nuclear Energy Commission, Rua Quatorze and Avenida Presidente Carlos Luz. The second area is bounded by BR-262, Rua Engenho Nogueira and Avenida Presidente Carlos Luz.

History

The site of the ESEC was once occupied by the Dalva farm, and later by the Don Orione Boys' Home, inaugurated by Juscelino Kubitschek in 1944. There are still some traces at the site of pottery and buildings from the past.
A proposal to create a conservation area on the campus was approved in January 1979.
A committee was formed, and on 29 July 1988 an agreement was signed with the city of Belo Horizonte.
The site, formerly abandoned and holding debris from the university, was restored and is now used for various research projects including a Master's course in Ecology Conservation and Wildlife Management.

Environment

The ESEC is an urban conservation area of  holding typical semi-deciduous forest and cerrado vegetation.
It has very diverse flora and fauna, including mammals such as capybara (Hydrochoerus hydrochaeris), black-tufted marmoset (Callithrix penicillata) and opossum (Didelphis), amphibians and reptiles such as Tupinambis lizards and False coral snakes, and about 150 species of birds including squirrel cuckoo (Piaya cayana),  toco toucan (Ramphastos toco), Penelope, Saíra and cinnamon tanager (Schistochlamys ruficapillus).
Vegetation includes native species such as Guazuma ulmifolia (Mutamba), Cedar, Ipê, Cotieira and exotic species such as Eucalyptus, Mango (Mangifera indica) and Baobab (Adansonia).

UPd2Al3. {{DISPLAYTITLE:UPd2Al3}}
UPd2Al3 is a heavy-fermion superconductor with a hexagonal crystal structure and critical temperature Tc=2.0K that was discovered in 1991. Furthermore, UPd2Al3 orders antiferromagnetically at TN=14K, and UPd2Al3 thus features the unusual behavior that this material, at temperatures below 2K, is simultaneously superconducting and magnetically ordered.
Later experiments demonstrated that superconductivity in UPd2Al3 is magnetically mediated, and UPd2Al3 therefore serves as a prime example for non-phonon-mediated superconductors.

Discovery
Heavy-fermion superconductivity was discovered already in the late 1970s (with CeCu2Si2 being the first example), but the number of heavy-fermion compounds known to superconduct was still very small in the early 1990s, when Christoph Geibel in the group of Frank Steglich found two closely related heavy-fermion superconductors, UNi2Al3 (Tc=1K) and UPd2Al3 (Tc=2K), which were published in 1991. At that point, the Tc=2.0K of UPd2Al3 was the highest critical temperature amongst all known heavy-fermion superconductors, and this record would stand for 10 years until CeCoIn5 was discovered in 2001.

Metallic state
The overall metallic behavior of UPd2Al3, e.g. as deduced from the dc resistivity, is typical for a heavy-fermion material and can be explained as follows: incoherent Kondo scattering above approximately 80 K and coherent heavy-fermion state (in a Kondo lattice) at lower temperatures. Upon cooling below 14 K, UPd2Al3 orders antiferromagnetically in a commensurate fashion (ordering wave vector (0,0,1/2)) and with a sizable ordered magnetic moment of approximately 0.85 μB per uranium atom, as determined from neutron scattering.

The metallic heavy-fermion state is characterized by a strongly enhanced effective mass, which is connected to a reduced Fermi velocity, which in turn brings about a strongly suppressed transport scattering rate. Indeed, for UPd2Al3 optical Drude behavior with an extremely low scattering rate was observed at microwave frequencies. This is the 'slowest Drude relaxation' observed for any three-dimensional metallic system so far.

Superconducting state
Superconductivity in UPd2Al3 has a critical temperature of 2.0K and a critical field around 3T. The critical field does not show anisotropy despite the hexagonal crystal structure.
For heavy-fermion superconductors it is generally believed that the coupling mechanism cannot be phononic in nature. In contrast to many other unconventional superconductors, for UPd2Al3 there actually exists strong experimental evidence (namely from neutron scattering  and tunneling spectroscopy ) that superconductivity is magnetically mediated.

In the first years after the discovery of UPd2Al3 it was actively discussed whether its superconducting state can support a Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) phase, but this suggestion was later refuted.

Zman Switch. The ZMAN Switch is a patented specialized Shabbos clock marketed to the observant Jewish market. Unlike a traditional timer, it contains a pre-programmed Jewish calendar through the year 2050, so that the consumer does not need to readjust the programming for sunset times or Jewish holidays throughout the year.  It is manufactured by ZMAN Technologies located in New Jersey and invented by Yonason Bloch and Herbert Klein.

Progress MS-07. Progress MS-07 (), identified by NASA as Progress 68P, was a Progress spaceflight, operated by Roscosmos to resupply the International Space Station (ISS).

History 
The Progress-MS is an uncrewed freighter based on the Progress-M featuring improved avionics.  This improved variant first launched on 21 December 2015. It has the following improvements:

 New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03.
 Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism.
 Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment.
 Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations.
 GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination.
 Real time relative navigation thanks to direct radio data exchange capabilities with the space station.
 New digital radio that enables enhanced TV camera view for the docking operations.
 The Ukrainian Chezara Kvant-V on board radio system and antenna/feeder system has been replaced with a Unified Command Telemetry System (UCTS).
 Replacement of the Kurs A with Kurs NA digital system.

Launch 
After a two-day delay, the Progress MS-07 lifted off on 14 October 2017, at 08:46:53 UTC. The spacecraft docked at the station on 16 October 2017, at 11:04:07 UTC. Progress MS-07 was launched from the Baikonur Cosmodrome in Kazakhstan, atop a Soyuz-2.1a rocket.

Docking 
Progress MS-07 was docked with the aft docking port of the Pirs module. This Progress flight was intended to mark the debut of the new two-orbit rendezvous profile which was not possible when the original launch date had to be scrubbed.

Cargo 
The Progress MS-07 spacecraft delivered 2,549 kg of cargo and supplies to the International Space Station for the six-person crew.
The following is a breakdown of cargo bound for the ISS:

 Dry cargo: 1,382 kg
 Fuel: 700 kg (for Zvezda service module)
 Oxygen: 23 kg
 Air: 24 kg
 Water: 420 kg

Spacewalk 
Once the Progress arrived at the station, Expedition 53 commander Randolph Bresnik and flight engineer Joseph M. Acaba prepared for a spacewalk, on 20 October 2017, to accomplish a variety of maintenance tasks outside the complex. This included the replacement of a fuse on the station's Canadian-built Dextre robot, replacing an external camera and light fixture, and removing thermal insulation from two spare units to prepare them for future relocation.

Undocking and decay 
Progress MS-07 undocked from the Pirs on 28 March 2018, at 13:50:30 UTC. The vehicle continued with experiments until 26 April 2018.
