## Nir Technology For Routine Analysis Of Food And Agricultural Products

Demographic & Epidemiological Transition Model [AP Human Geography Unit 2 Topic 5] (2.5)

Near Infrared analysis is a spectroscopic technique that makes use of the naturally occurring electromagnetic spectrum.The NIR region is the area of the spectrum defined by wavelengths between 700nm and 2500nm. Near Infrared is an accurate and rapid analysis method that is well suited for quantitative determination of the major constituents in most types of food and agricultural products. The NIR advantageThe overall advantages of using NIR analysis is that it provides rapid analysis data for better decision making in food and agri production processes. Compared to traditional analysis methods it requires little or no sample preparation and no chemicals or consumables. It is non-destructive, operator friendly, fast , reliable and precise.How it worksThe working principle can be defined as follows:

• Near Infrared light is directed onto a sample
• The light is modified according to the composition of the sample and this modified light is detected
• The spectral modifications are converted to information regarding the composition of the sample
• These conversion algorithms are called calibrations

An infrared spectrum can be obtained by passing infrared light through a sample or the light can be reflected from the sample .

## Why Do Females Live Longer

Yet women continue to live longer than men, suggesting the biological differences also have a role. Experts shave said the gap is due to a combination of biological and social differences. Mens hormone testosterone is linked to a decrease in their immune system and risk of cardiovascular diseases as they age.

## Examples Of Calculating Rni

Lets look at a couple of examples. In Nicaragua, the birth rate is 20/1,000 and the death rate is 5/1,000. Following the formula for finding RNI

20/1,000 5/1,000 = 15/100015 divided by 1,000 = 0.015 which when converted to a percentage equals 1.5%

So Nicaraguas rate of natural increase is 1.5%.

An RNI percentage larger than zero indicates a growing population. In some countries, like Germany, the death rate is larger than the birth rate, which causes a negative percentage. In the case of Germany, the birth rate is 9/1,000 and death rate is 11/1,000, resulting in an RNI of -0.2%. A negative RNI indicates a decreasing population size.

However its important to remember that this growth rate does NOT account for change based on migration, which can have a significant impact on a countrys overall rate of population change.

Rate of natural increase by country

Currently, Niger has the highest RNI, growing at 3.78%, and Bulgaria has the lowest, at -2.79%. The United States rate of natural increase is -0.65%.

## What Is The Global Average Tfr

According to World Bank data, the global fertility rate was 2.4 children per woman in 2019. This rate is approximately half of what it was in 1950 , and more economically developed countries such as Australia, most of Europe, and South Korea, tend to have lower rates than do less-developed or low-income countries.

## Stage : High Growth Rate

Around the mid-1700s, global populations began to grow ten times faster than in the past for two reasons: The industrial revolution and increased wealth. The Industrial Revolution brought with it a variety of technological improvements in agricultural production and food supply. Increased wealth in Europe and later North America because of the Industrial Revolution meant that more money and resources could be devoted to medicine, medical technology, water sanitation, and personal hygiene. Sewer systems installed in cities led to public health improvements. All of this dramatically caused CDRs to drop around the world. At first, CBRs stayed high as CDRs decreased this caused populations to increase in Europe and North America. Over time, this would change.

Africa, Asia, and Latin America moved into Stage 2 of the demographic transition model 200 years later for different reasons than their European and North American counterparts. The medicine created in Europe and North America was brought into these emerging nations, creating what is now called the medicalrevolution. This diffusion of medicine in this region caused death rates to drop quickly. While the medical revolution reduced death rates, it did not bring wealth and improved living conditions and development that the Industrial Revolution created. Global population growth is highest in the regions that are still in Stage 2.

## Why Are Ap Human Geography Scores Curved

Advanced Placement exams are designed to model college courses, many of which are curved. Also, one of the primary goals of the College Board is to maintain exam consistency over the years, even though the test questions change. So, the scoring guidelines are reflected to account for these needs. Make sure to note that since there is a curve, a 5 can be difficult to achieve. The curve is designed to give the majority of students a score of 3, which is why in 2016, only 12% of test takers received a 5.

## An Introduction To Near Infrared Spectroscopy

A.M.C. DaviesNorwich Near Infrared Consultancy, 10 Aspen Way, Cringleford, Norwich NR4 6UA, UK

When you hold your hand out to a burning fire you feel the heat being emitted by the fire but what is happening? The fire gives out light and infrared radiation from a fire most of this is near infrared radiation. Some of the NIR radiation is absorbed by water molecules in your skin. This raises the temperature of the water and results in an increase in temperature in the surrounding tissue which is detected by nerves in your skin. This radiation was discovered in 1800 by William Herschel, a musician and very successful amateur astronomer because he wanted to know if any particular colour was associated with heat from sunlight. He found that the heat maximum was beyond the red end of the spectrum. Herschel could not believe that light and his radiant heat were related but he was wrong. By 1835 Ampere had demonstrated that the only difference between light and what he named infrared radiation was their wavelength. Then in 1864 James Maxwell wrote This velocity is so nearly that of light that it seems we have strong reason to conclude that light itself is an electromagnetic disturbance in the form of waves propagated through the electromagnetic field according to electromagnetic laws. What we now call the electromagnetic spectrum is shown in Figure 1.

## Key Factors Influencing Population Change

Three key factors to understand when trying to predict or analyze population change are the total fertility rate, infant mortality rate, and life expectancy at birth. Total fertility rate is the average number of children a woman would be expected to have during childbearing years . The global average for TFRs is about 2.5, but in less developed countries, it is as high as 5.0 or higher, and in more developed countries, it is as low as 2.0 or less. Fertility patterns can vary widely within countries. Racial and ethnic minorities may have higher fertility rates than the majority, and families with low incomes or low levels of education typically have more children than those that are affluent or well-educated. Women who work outside the home typically have fewer children than those who stay home, and rural families tend to have more children than city dwellers. In 2016, the number of births per 1,000 people worldwide was 20, with extremes ranging from a low of 8 or 9 , to 60 or more in a few West African nations .

## Chapter 7 Population And Migration

Understanding how the human population is organized geographically helps us make sense of cultural patterns, the political organization of space, food production issues, economic development concerns, natural resource use and decisions, and urban systems. Additionally, themes of location, space, place, the scale of analysis, and pattern can be emphasized when studying fundamental population issues such as crude birth rates, crude death rates, total fertility rate, infant mortality rates, doubling time, and natural increase.

Explanations of why the population is growing or declining in some places are based on patterns and trends in fertility, demographic mortality, and migration. Analyses of refugee flows, immigration, and internal migration help us understand the connections between population phenomena. For example, environmental degradation and natural hazards may prompt population redistribution at various scales, which in turn creates new pressures on the environment, culture, and political institutions.

This chapter will analyze population trends across space and time as ways to consider models of population growth and decline, including Malthusian demographic transition, and the epidemiological transition model.

## How Do You Calculate Ndvi

2.4 Population Dynamics (Unit 2: Population & Migration, Topic 4 of AP Human Geography)

As shown below, Normalized Difference Vegetation Index uses the NIR and red channels in its formula.

Healthy vegetation reflects more near-infrared and green light compared to other wavelengths. But it absorbs more red and blue light.

This is why our eyes see vegetation as the color green. If you could see near-infrared, then it would be strong for vegetation too. Satellite sensors like Landsat and Sentinel-2 both have the necessary bands with NIR and red.

The result of this formula generates a value between -1 and +1. If you have low reflectance in the red channel and high reflectance in the NIR channel, this will yield a high NDVI value. And vice versa.

Overall, NDVI is a standardized way to measure healthy vegetation. When you have high NDVI values, you have healthier vegetation. When you have low NDVI, you have less or no vegetation. Generally, if you want to see vegetation change over time, then you will have to perform atmospheric correction.

Reincarnation is a belief that upon death, your soul will return to another body. An incarnation of someone is the act or process by which that person comes to be in his present form.

## Absorptions In The Nir Region

If chemical bonds behaved exactly like weak springs then quantum mechanics would restrict their vibration to just two states and there would be very few absorptions in the NIR region. Absorptions in the NIR region are generated from fundamental vibrations by two processes overtones and combinations. Overtones can be thought of as harmonics. So every fundamental will produce a series of absorptions at multiples of the frequency . Combinations are rather more complex. NIR absorptions are at a higher state of excitement so they require more energy than a fundamental absorption. Combinations arise from the sharing of NIR energy between two or more fundamental absorptions. While the number of possible overtones from a group of fundamental absorptions in a molecule are limited to a few, a very large number of combinations will be observed. The effect of all these absorptions combine to make many NIR spectra to look rather uninteresting and to consist of only a few rather broad peaks. Figure 2 is an NIR spectrum of chloroform, CHCl3, the molecule contains only one hydrogen atom but all the absorption in its spectrum are caused by this single atom.

## Geography & Natural History

Map of Nir Province

Nir is a region dominated by low-lying swamps, and has a humid subtropical climate with hot summers and mild winters. It is frequently rainy due to its location on the Gulf of Heaven, which brings large storms during the summer months.

Millions of years ago during the Tyrfinic Period, Nir was still swampy, however different kinds of plants and animals lived there. The swampy land was favorable for the formation of peat and fossils, as both the bones of animals , plant fossils, and large coal deposits can be found in the shale and mudstone that make up what are now known as the Sokalis Coal Measures. The ancient swamps also collected lots or iron, which was used by later inhabitants to craft tools.

An artist’s reconstruction of what the coal swamps of Nir looked like roughly 260 million years ago.

A period of geologic uplifting known as the Sokalian Orogeny would turn the swamps into mountains, and faulting in the rock allowed for various granitic plutons to form. This new layer of igneous and metamorphic rock would provide an aquifuge, preventing the Nir Aquifer from saturating the lower rock strata. Without the aquifuge, the lower rocks would be saturated with water and any mines would flood.
