--------------- LECTURE 4: ------------------ INSPECTION: Experts evaluate interface without involving users. Goal: Identify usability problems early in design. Advantages: Cheap, fast, early design feedback. Disadvantages: Depends on expert judgment, may miss real user issues. ----------- TYPES OF INSPECTION METHODS: 1.) Heuristic Evaluation, 2.) Cognitive Walkthrough, 3.) Pluralistic Walkthrough, 4.) Guidelines Review, 5.) Consistency Inspection. ----------- HEURISTIC EVALUATION: Developed
...f) Define (i) Diffusion current (ii) Drift current & (iii) Barrier potential in a pn junction.
Ans:
1. Diffusion Current: Due to the concentration gradient,
majority carriers move across the junction (holes from p-side to n-side and electrons from n-side to p-side). This motion constitutes the diffusion current.
2. Drift Current: The electric field in the depletion region
causes minority carriers to move across the junction (holes from n-side to p-side and electrons from p-side to n-side). This
Interaction Design (IxD): Designing interactive products to support the way people communicate and interact in their everyday and working lives. Winograd → “Designing spaces for human communication and interaction. Thackara → Focuses on the why and how of daily interactions. Saffer → “Art of facilitating interactions between humans through products and services.” Key idea: It’s about creating good user experiences, not just working systems. -------- Goal of interaction design: Reduce...
Like the lumen of the ER, the interior of the nucleus is topologically equivalent to the outside of the cell. (F)
Researchers in a biotechnology company has discovered a drug that blocks the ability of Ran to exchange GDP for GTP. What is the most likely eect of this drug on nuclear transport? (C. Nuclear transport receptors would be unable to release their cargo in the nucleus. )

Definition:
A constructor is a special member function of a class that is automatically called when an object of the class is created. It is mainly used to initialize the data members of the class. The constructor has the same name as the class and it does not have any return type
Characteristics:
1)Constructor name is same as the class name.
2)It has no return type (not even void).
3)It is automatically executed when the object is created.
4)It initializes the data members of the class..

Wojna peloponeska
431–404 p.n.e.
Ateny (Związek Morski) vs Sparta (Związek Peloponeski)
Główna przyczyna: walka o hegemonię w Grecji
Kluczowe wydarzenia: • zaraza w Atenach (430–426), śmierć Peryklesa • klęska Aten na Sycylii (413) • zajęcie Dekelei przez Spartę
Zakończenie: klęska Aten, zburzenie murów Długich, oligarchia 30 tyranów (404 p.n.e.) → upadek potęgi Aten, osłabienie całej Grecji
Początek potęgi Macedonii / Filip II
Filip II → król 359–336 p.n.e.
