Coffee is a plant and drink made from its seeds, called coffee beans. The coffee plant is a bush or tree originally from Africa that is now grown in parts of South America, Central America, and Southeast Asia. To make coffee, the beans must be dried, roasted, and ground before being brewed in boiling water, which extracts the flavor and brown color from the beans. There are several methods for brewing coffee, which is a popular drink around the world due to its caffeine content.
This document discusses the principles of Feng Shui design for office spaces. It explains that Feng Shui aims to balance the Chi energy in a space so it flows optimally. There are two types of Chi - Yin and Yang, which represent opposite forces, and the Five Elements of water, wood, fire, metal and earth. The document provides color recommendations for each area of the Bagua map and suggests objects to place in different areas to influence different aspects of life, such as career, creativity or wealth. It emphasizes the importance of an organized, clutter-free space and decorating in a way that makes the office enjoyable.
WTF - Why the Future Is Up to Us - pptx versionTim O'Reilly
This is the talk I gave January 12, 2017 at the G20/OECD Conference on the Digital Future in Berlin. I talk about fitness landscapes as applied to technology and business, the role of unchecked financialization in the state of our politics and economy, and why technology really wants to create jobs, not destroy them. (There is a separate PDF version, but some readers said the notes were too fuzzy to read.)

Samoilă Mârza was a photographer born in 1886 who immortalized the important moments of Romania's Great Union in 1918, including photographing the ceremony in Alba Iulia where the Union was finalized. As the only photographer to capture these historic events, Mârza made five photographs of the Grand National Assembly in Alba Iulia using an old bellows camera. Although his work was historically significant, Mârza lived in poverty and continued using the same old camera for 60 years. He died in 1967, leaving many projects unfinished.
Iuliu Maniu was a Romanian politician who served as Prime Minister of Romania for three terms between 1928-1933. He was a leader of the National Party of Transylvania and Banat before and after World War I, and co-founded the National Peasants' Party. Maniu was born in Austria-Hungary (now Romania) to an ethnic Romanian family and studied law in universities in Budapest and Vienna, receiving his doctorate in 1896. He advocated for the liberation and union of Transylvania with Romania.

Hallstatt is an Austrian village located on the western shore of Lake Hallstatter See. It has a population of 946 and is known for its production of salt dating back to prehistoric times. The village gave its name to the early Iron Age Hallstatt culture. Some of the earliest evidence of the Celts was found in Hallstatt. Tourists can visit the world's first known salt mine above the downtown area. In winter, Hallstatt offers over 60 km of ski slopes ideal for families with modern ski lifts and cable cars.
Bibury is a village located in the Cotswolds of England known for its beautiful stone buildings and idyllic scenery. The main street, Arlington Row, has 17th century stone cottages that were originally used as wool warehouses. Notable attractions include the Arlington Mill, which is now a folk museum, and the Bibury Trout Farm, which produces over 10 million trout annually. The largest building is Bibury Court, built in 1633 in the Jacobean style. The village and surrounding area attract many tourists wishing to experience the traditional rural charm of the Cotswolds.
Energy conservation involves using less energy to achieve the same results through behaviors like turning off lights when not in use, using more efficient appliances, and adopting modes of transportation that use less fuel. It helps save money on utility bills and preserves natural resources that produce energy. Individual actions like lowering the thermostat, taking shorter showers, and air drying clothes can collectively make a big difference and benefit both personal finances and the environment long-term.
Magurele is a city in Ilfov County, Romania located in the southwestern vicinity of Bucharest and serves as a satellite city to the capital. Magurele is home to the premises of two prominent Romanian research institutes, the Institute of Atomic Physics and the Physics Research Institute of the Earth.
Peris is a commune located in northwest Romania along the Snagov valley. It consists of five villages - Peris, Bratulesti, Cocioc, Balteni, and Burias - situated between the Ialomita River and Lake Snagov. Some tourist attractions in the area include the Hermitage of Balteni, a 17th century monastery built following a prince's dream, and the Scrovistea Palace, once belonging to the Romanian royal family and home to members of the Hohenzollern dynasty. Casa Enache offers accommodation and relaxation for tourists visiting the region.
Coffee is a brewed drink made from roasted coffee beans, which come from the seeds of Coffea plant berries native to Africa. The Coffea plant has been exported around the world and is now cultivated in over 70 countries, primarily in equatorial regions. Coffee beans are picked, processed, dried, roasted, ground, and brewed to produce the popular beverage. Coffee contains caffeine and can have a stimulating effect on humans, making it one of the most popular drinks globally.
2. 1.Introducere
Efectul termoelectric reprezinta propietatile a doua metale diferite puse in contact,cand acestea
au temperaturi diferite. Daca circuitul format din cele doua metale este inchis,in el apare un
curent,numit curent termoelectric. Acesta exista atata timp cat T1 este diferit de T2.
Efectul Seebeck este efectul termoelectric direct si consta in aparitia unei tensiuni
electromotoare intr-un circuit compus din doi sau mai multi conductori electrici cu temperaturi
diferite.
Efectul Peltier reprezinta absorbtia de caldura dintre doua corpuri conductoare,atunci cand prin
acestia trece curent electric.
Efectul Thomson reprezinta trecerea curentului electric printr-un conductor,supus unui gradinet
de temperatura.
Aceasta lucrarea are ca scop exemplificarea efectului Seebeck si Peltier,cu ajutorul unor celule
dintr-un material semiconductor de o grosime neglijabila.
Celulele sunt in contact cu o sursa calda si o sursa rece,fapt ce va ajuta la determinarea
caracteristicilor de mers in gol si scurtcircuit.
Etapele rezolvarii aplicatiei
Dupa ce am construit geometria,am definit coeficientii si constantele,si am pus conditiile de
frontiera,am analizat schimbarile ce au avut loc in interiorul celulei.
In figura1,este reprezentata densitatea de curent electric (prin sagetile albe) pe suprafata celulei
semiconductoare.
(figura1)
3. In figura2 ,este reprezentata distributia de cutent electric in regimul de functionare de mers in
gol ,observandu-se astfel ca densitatea de curent in acest regim este foarte mica.
(figura.2)
(Figura3)
4. In figura3,se poate observa distributia de temperatura pe suprafata celulei si de asemenea,fluxul
de caldura pe aceasta (reprezentata de sagetile albe)
