Congress: The Big Lessons From Two Recent Congresses
Obamacare (2300-page law) narrowly passed on strict party lines in 2010. 45% of the public approves
Republicans took over the House in 2010; in 2014, they took over the Senate, too. Congress has passed over 60 bills to repeal and replace Obamacare
But that doesn’t happen. Why?
Obama vetoed each bill.
2017? RS is completely controlled, but Obamacare is more popular, with more electoral pressure.
Repeal passes House, but
The Spiral Model, proposed by Barry Boehm in 1986, is a software development process model that combines elements of both the Waterfall Model and Prototyping. It is mainly used for large, complex, and high-risk projects where requirements are not well understood from the beginning.
Each loop (iteration) of the spiral represents a phase in the software process and includes four major activities:

Chapter 13 covers bacterial genome replication and expression. Griffith’s transformation experiment demonstrated that non-virulent bacteria could become virulent by absorbing DNA from dead virulent cells, proving that DNA is the genetic material. The Hershey and Chase experiment used radioactive labeling (phosphorus for DNA and sulfur for protein) to confirm that only DNA enters bacterial cells during phage infection, further establishing DNA as the genetic material. DNA has a double-helix structure
Chapter 13 – Bacterial Genome Replication and Expression Transformation Experiment: Griffith’s experiment showed that non-virulent bacteria could transform into virulent forms by taking up DNA from dead virulent cells. It proved DNA is the genetic material. Hershey and Chase Experiment: Used radioactive labeling (P for DNA, S for protein) to show that only DNA enters bacterial cells during phage infection. Proved DNA is the genetic material. Structure of DNA: Double helix of two antiparallel
Data Dictionary
A data dictionary is a centralized repository that defines the structure, relationships, and attributes of data elements used in a system. It includes names, types, sizes, allowable values, and descriptions of each data element. Used in databases and software development, it ensures consistency, clarity, and data integrity. It serves as a reference for developers, analysts, and stakeholders, improving communication and system documentation.

a) Continued and Timed Injection Systems:
• Continued injection delivers fuel continuously into the intake manifold, regardless of the engine cycle.
• Timed injection synchronizes fuel delivery with the intake stroke of each cylinder for better efficiency and combustion control.
b) Functions of Piston Rings:
1. Seal the combustion chamber to prevent gas leakage.
2. Control oil consumption by scraping excess oil from the cylinder walls.
3. Transfer heat from the piston to the cylinder wall.
Objectives of Lubrication
Primary Objectives:
1. Reduce Friction – Minimizes resistance between moving parts.
2. Minimize Wear – Protects surfaces from damage and extends component life.
3. Dissipate Heat – Carries away heat generated due to friction.
4. Form Protective Film – Prevents direct metal-to-metal contact.
5. Enhance Efficiency – Reduces energy losses during operation.
Secondary Objectives:
1. Prevent Corrosion – Acts as a barrier against moisture and chemicals.
2.
