EU Single Market: Rules on Tariffs, Taxes, and Non-Tariff Barriers

Classified in Law & Jurisprudence

Written on in English with a size of 4.47 KB

The aim is to create a single market in the EU where products can move as if there were no borders. This means NO:

  • Customs duties between countries
  • Hidden charges (CHEEs)
  • National rules that make trade harder (MEEs)
  • Taxes that discriminate against foreign products

Exceptions are only allowed when they are justified (e.g., health, safety, morality, etc.) and pass the proportionality test.

Prohibition of Tariffs and Charges (Art. 30 TFEU)

Prohibited between Member States:

  • Customs duties (aranceles): A monetary charge for crossing a border. Always prohibited, even if small or non-protectionist.
  • CHEEs (Charges Having Equivalent Effect): An impuesto disfrazado de otra cosa (tax disguised as something else). A unilateral charge on imports/exports not linked

Recombinant DNA, Chemiosmosis, and Electron Transport Chain

Posted by Anonymous and classified in Biology

Written on in English with a size of 6.38 KB

Constructing Recombinant DNA

The following steps are involved in the construction of recombinant DNA:

  1. Preparation of the Gene: Gene cloning in bacteria is achieved by cleaving DNA with enzymes called restriction endonucleases, which create small fragments. Each fragment often has a "sticky end." Since eukaryotic genes contain introns that are not processed in bacteria, the DNA for cloning is usually obtained from relevant mRNA through the process of reverse transcription. In cases where nucleotide or amino acid sequences are known, synthetic DNA may also be produced.
  2. Insertion into a Vector: The vector is a vehicle, such as a plasmid or bacteriophage, used to transfer DNA into a host cell. The vector is cut with the same restriction endonuclease

English Language Levels and Learning Activities

When planning activities, we must consider the students' English level, with the help of the course materials and their textbooks.

First and Second Year Students

  • Encourage the use of adjectives, nouns, and general vocabulary in phrases and longer sentences.
  • Writing is very limited at this stage.
  • Activities: Circle, draw, match, associate.

Third and Fourth Grade Students

  • Encourage greater independence.
  • Activities: Complete sentences, fill in the blanks, answer questions, short writing tasks.

Fifth and Sixth Grade Students

  • Expect them to develop critical thinking and use a variety of adjectives, nouns, and verbs.
  • Activities: Write paragraphs, descriptive writing, opinion pieces, compare and contrast, summarize

Astronomy = study of celestial objects and their interactions.                                    

Scientific method: relies on observation, testing, and revision.

Distances measured in light-years; light travels at ~300,000 km/s

Scientific notation helps handle large/small numbers.  γ

Observing the Sky

Constellations = regions in the sky (88 official).

Sky appears to move due to Earth’s rotation (24h) and orbit (365 days).        

Zenith = overhead; meridian = N to S through zenith.

Operations: Key Questions for Value Creation

  • What processes create value? Example: Amazon with its automated logistics.
  • What activities support these processes? Example: Google heavily invests in R&D and qualified HR.
  • What external factors influence operations? These include globalization, offshoring, and digitalization. Example: Nike manufactures in Asia to cut costs.
  • What are the key considerations for internationalization in operations? Culture, costs, laws, and partners are crucial. Example: IKEA adapts its products to the Chinese market.
  • What common mistakes should be avoided in operations? A local mindset, lack of market study, and unclear contracts can lead to failure. Example: Walmart failed in Germany due to cultural mismatch.

B.R. Ambedkar's Economic Criticism of Caste

Ambedkar propounded a powerful economic critique of the caste system, arguing that it was fundamentally inefficient and anti-meritocratic.

  1. Caste as a System of Division of Labourers (Not Labour): It divides people based on birth, restricting occupational mobility.
  2. Stifling of Competition and Innovation: Fixed occupations prevent talent from flourishing.
  3. Denial of Economic Opportunity: Opportunities are restricted to specific caste groups.
  4. Caste and the Closed Economy: The system discourages trade and interaction outside the caste group.
  5. Opposition to Industrialization and Modernization: Caste structures resist necessary economic changes.
  6. Economic Inefficiency: The system is wasteful and suppresses talent.
