Beautiful Bungalow in Alicante

The bungalow is perfectly situated in the south of Alicante, near the beach. You can spend your holidays very comfortably. On the one hand, the bungalow has two floors. On the first floor, there are a kitchen, a bathroom, and a big living room. Also, it has a garden.

Essential Characteristics

1. Incorporation

   The rights are tied to the writing. The instrument contains a right given by the document. Possession of the writing evidences the right.

2. Legitimation

   The person holding the instrument has the power to demand payment of the credit within.

3. Accuracy

   The terms of the instrument cannot be modified or amended from the moment of its creation.

4. What is accurately written in the text of the instrument becomes the right.

5. Autonomy

   The instrument is born when it is drafted and negotiated by its original maker.

   1. There is a personal relationship between the maker and the first holder. This repeats as it transfers from one hand to another.

   2. The instrument becomes more abstract, autonomous and independent from the reasons it was

Legal Theories on the Nature of Credit Instruments

1. Contractual Theory

   Contractual Theory. Influenced by civil law tradition, this theory states that the fundamental obligation of the legal relationship exists between the debtor and the creditor. The legal value of the document lies in the underlying transaction, not merely in the writing itself. It is not a declaration of intent but a mere detachment of the document, which establishes the concurrence between its content and the declaration, thereby giving birth to a commercial transaction through the submission of the document.

2. Unilateral Theory

   Unilateral Theory. The obligation is born from a simple unilateral promise, rather than an offer from the maker requiring acceptance or drafting and subscription.

SWOT is an acronym that stands for Strengths, Weaknesses, Opportunities, and Threats. A **SWOT analysis** is an organized list of your business’s greatest strengths, weaknesses, opportunities, and threats.

Strengths and weaknesses are internal to the company (think: reputation, patents, location). You can change them over time, but not without some work. Opportunities and threats are external (think: suppliers, competitors, prices)—they are out there in the market, happening whether you like it or not. You cannot change them.

Rutherford Experiment

The results of the gold foil experiment led to the discovery of a very densely packed bundle of matter with a positive electric charge. Rutherford called this positive bundle of matter the nucleus.

Thirdly, impressionist descriptions, symbols, and motifs in the novel contribute to addressing Modernism's issues. Influenced by Joseph Conrad's language in Heart of Darkness, Fitzgerald opts for impressionistic, picturesque language, often using figures of speech. Examples include "Yellow Cocktail Music," "Velvet Dusk," "Blue Gardens," "Vividness," and Daisy's voice, described as "exhilarating" and engaging, with musical ups and downs.

Fitzgerald uses recurring symbols: The green light (hope), seen when Gatsby and Daisy reunite after five years; The clock (remaining time for Gatsby and Daisy) in the same scene; Daisy's destroyed letter from Gatsby (their resigned love's end); The blue light (sadness and melancholy); Gatsby's mansion (wealth...
