Published on: March 20, 2014
Summary
The post-war mortality decline in Ceylon remains debated. This study re-examines past work, focusing on malaria control
Area of Science:
- Demography
- Public Health History
Background:
- The causes of the post-war mortality decline in Ceylon are subject to ongoing debate.
- Previous research offers various explanations, necessitating a synthesis and re-evaluation of existing theories.
Purpose of the Study:
- To re-examine past research on the mortality decline in Ceylon.
- To synthesize previous theories and assess the validity of regression models used in demographic analysis.
- To evaluate Meegama's thesis on confounding variables impacting the relationship between mortality decline and malaria prevalence.
Main Methods:
- Reappraisal of existing studies on mortality decline in Ceylon.
- Assessment of Newman's regression model.
- Evaluation of Meegama's thesis regarding confounding variables.
Main Results:
- The study acknowledges insufficient data for a definitive account of all causal mechanisms.
- Focuses on the validity of regression models and the impact of confounding variables.
- Responds to specific points raised by Mr. Palloni regarding demographic analysis.
Conclusions:
- The complexity of the post-war mortality decline in Ceylon requires further investigation.
- The limitations of current data necessitate a cautious approach to causal inference.
- Further discussion on regression models is needed to understand demographic shifts.

01:18Parseval's Theorem
Parseval's theorem is a fundamental concept in signal processing and harmonic analysis. It asserts that for a periodic function, the average power of the signal over one period equals the sum of the squared magnitudes of all its complex Fourier coefficients. This theorem, named after Marc-Antoine Parseval, provides a powerful tool for analyzing the energy distribution in signals.
Interestingly, Parseval's theorem also holds for the trigonometric form of the Fourier series, which expresses a...

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
01:20Amides to Amines: LiAlH4 Reduction
Amide reduction with strong reducing agents like lithium aluminum hydride proceeds through a nucleophilic acyl substitution to form amines. Primary, secondary, and tertiary amides yield primary, secondary, and tertiary amines, respectively.
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

01:11P-N junction
A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...
01:12Porin Insertion in the Outer Mitochondrial Membrane
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

01:23Parallel Resonance
The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:
