Design and Product Development
The goods and services a company can produce are varied, and their nature depends largely on the productive process design. If the company’s product meets consumer needs in quality and functionality, the company will see increased turnover. Product selection is key for organizational success. After selecting the product, the next step is designing it to meet market requirements, environmental constraints, and organizational

Physics Essentials: Vibrations, Waves, Gravity, Fields, Optics
Vibratory Motion (MAS) – Radians
X(t) = a sin (wt + fi), A = xmax
w = 2π / T = 2πnu, nu = 1/T = 1/nu
vtransversal = dx / dt
a = –w2 · x
x = Acoswt = acos (wt + π/2)
v = Awcos (wt + fi), vmax = Aw
v = ±w · √(A2–x2)
F = –kx, K = Mw2-√ w = k / m (kN/m)
Simple Pendulum – Theta
θ = s / l
T = 2π · √(L / g)
s = θ x L
cos θ = Lh / L
w = √(g / L)
θ(t) = θm sin (wt + fi) – fi then removed

Habeas Corpus: Ensuring Lawful Detention
Habeas corpus mandates the immediate presentation of a detainee before a judge to rule on the legality of detention, as per Article 17.4 of the Constitution. This procedure focuses solely on the immediate pre-trial detention, serving as a means to cease irregular deprivation of liberty. The application for habeas corpus must be made to the judge where the person is detained and can be initiated by:
- The detainee, spouse, or similar relation, descendants, ascendants,
Kidney Structure and Function
Renal Structure
The kidneys are bean-shaped organs located in the back of the abdomen, behind the peritoneum, on each side of the spinal column. They measure about 12 x 6 x 3 cm and weigh between 130 and 150 g. The final product is urine, excreted through the urinary system.
Urine produced by the kidneys is collected in the renal pelvis, flows through the ureters into the bladder, and exits through the urethra.
The functional unit is the nephron. Each kidney contains 600,000 to >1,000,000 nephrons.

European Regional Policy
European regions have varying population and production levels, leading to inequalities. To address this, the EU established a regional policy, utilizing Structural and Cohesion Funds from its annual budget. Initially, Spain and Portugal’s regions were less developed and received substantial funding. However, post-2004, with Eastern European countries joining, funds were redirected to their less developed regions.

Ontology: Theory of Ideas
Theory of Ideas: The acceptance of absolute realities, eternal, immutable, universal, and independent of the world we perceive through the senses. Concrete things in this world are just, beautiful, or good due to their participation in absolute ideas of justice, beauty, and goodness. They are imperfect realizations of these absolute ideas.
Platonic ideas are realities that exist independently of things.
Aristotle believed that the doctrine of ideas resulted from Heraclitus’

Thomas Aquinas
Context
Aquinas lived in the 13th century and belonged to the Dominican order. He studied and taught at the University of Paris, where his teacher was Albert the Great. The 13th century marked the zenith of the medieval world and the decline of feudal society. Cities grew, leading to the rise of the bourgeoisie, economic stability, and flourishing trade. Culturally, the era saw the rise of universities and the reception of Greek, Arab, and Jewish philosophical translations, making it
