Définition de l’entrepreneuriat
L’entrepreneuriat consiste à créer de la valeur à travers un produit ou un service.
Cette valeur doit répondre à un besoin réel du marché.
L’objectif final est la création de revenus durables.
La création de valeur repose sur la mobilisation et la combinaison de ressources.
Elle ne se limite pas à l’innovation, mais à l’utilité perçue par le client.
Une valeur pertinente est utile, acceptée par le marché

DATABASE INTEGRATO : raccolta di dati, informazioni organizzate e gestite utilizzando il linguaggi di interrogazione SQL.
Perchè creare un database integrato ? La versione coerente e normalizzata di tutti i dati è utile in caso di grandi quantità di dati come nell'analisi dei Big data. Infatti l'integrazione consente di operare meglio attraverso operazioni sequel per confrontare diverse database
step 1 : ricerca delle fonti : da fonti ufficiali come istituiti di statistico, e verificare se
A system transforms input u(t) into output y(t). It can be continuous/discrete, linear/nonlinear, time-invariant/time-variant.
Signals: continuous/discrete, periodic/aperiodic, deterministic/random, energy/power signals.
Open loop: no feedback, control does not depend on output → simple but sensitive to disturbances/parameter changes.
Closed loop: uses feedback (compare reference r with output y, error e=r−y) → better accuracy
Relational model stores data in tables (relations): rows = tuples, columns = attributes.
Key components: tables, attributes, tuples, constraints (PK/FK/UNIQUE/NOT NULL).
Mapping ER → relational: entity → table, 1:many → FK on many side, many:many → junction table, multivalued attribute → separate table.
Functional dependency (FD): X → Y means X uniquely determines Y (same X → same Y).
Armstrong axioms: reflexivity (if

electric field:-the sphere arround a source change in which a test charge would experience a force is called electric field.
Electric field lines: An electric field is represented by same emajinary lines of force which are called electric field.
properties:-1)they are emajinary lines of force.
2)in case of positive source change they are readily directed outward.
3) they are not closed line.
mathematically define of electric field:- the electric force per unit test charge is called
A chemical reaction is a process in which one or more substances, known as reactants, undergo a transformation to form new substances with different chemical properties, known as products. During a chemical reaction, the arrangement of atoms in the reactants changes, leading to the creation of new bonds and the breaking of old ones. Chemical reactions are fundamental to understanding how matter interacts and changes in the world around us.
For example, hydrogen gas combines with

Important drug terms to know: 1. Onset: Time it takes for the drug to reach the minimum effective concentration 2. Peak drug level: highest drug concentration in the blood 3. Trough drug level: lowest concentration before next dose 4. Duration: Length of time the drug exerts a therapeutic effect 5. Side effects: Secondary drug effects 6. Adverse reactions: Unintentional or unexpected reactions 7. Drug interactions: Changed action of the drug as a result of interaction with another drug 8. Drug |
Mode of Occurrence of Igneous Rocks:- Igneous rocks are formed by the cooling and solidification of molten magma either beneath the Earth’s surface or on it. Their mode of occurrence is closely related to the depth of crystallization, the nature of magma intrusion, and the environment in which the magma solidifies. Broadly, igneous rocks occur in two main modes: intrusive (plutonic) and extrusive (volcanic).
Intrusive (Plutonic) Igneous Rocks:
These rocks form when magma cools slowly beneath the
