The document provides demographic information about Egypt's population including estimates, growth rates, and population structure. Some key points:
- Egypt's population in January 2017 was estimated at 92.1 million using natural increase method (births minus deaths).
- The population is distributed unevenly across governorates with Cairo and Alexandria having the largest populations at 10.4% and 5.4% respectively.
- Egypt's population is estimated to be 57.3% rural and 42.7% urban as of 2016.
- A population pyramid shows Egypt has a youthful population structure with over 35% under age 15.
- The crude birth rate, death rate, and other demographic indicators are included to
World population reached 7.5 billion in 2017 and is projected to continue growing, though more slowly, reaching 8 billion by 2025 and possibly 11 billion by 2100. The annual growth rate peaked in the 1960s at 2% but has since declined to about 1.1% currently. India has the second largest population in the world at over 1.2 billion according to the 2011 census, and its population is projected to surpass China's in the coming decades.
The document discusses population trends and distribution in Pakistan. It notes that Pakistan has experienced rapid population growth accompanied by large-scale internal migration, resulting in uneven population distribution across the country. The study analyzes factors influencing population growth and distribution such as fertility, mortality, migration, and government policies. It evaluates the impacts of migration on urbanization and recommends long-term population distribution policies and regional planning to address over-concentration of populations in large cities.

This document discusses population explosion as a threat to national security in Pakistan. It notes that Pakistan's population has grown rapidly from 45.9 million in 1960 to 178.9 million in 2012. This high population growth rate puts pressure on resources and can contribute to issues like poverty, unemployment, and social problems. If not addressed, an overpopulated country like Pakistan may face threats to national security and economic instability. The document advocates for family planning programs and increasing education and awareness to help control the population growth rate.
This document discusses the demography and population of Pakistan. It provides statistics on Pakistan's current population size, population growth rates, birth and death rates, and population projections. It also examines population dynamics and causes of overpopulation in Pakistan. Additionally, it outlines the demographic characteristics of Pakistan's population, including ethnicity, religions, languages, age structure, literacy rates, education levels, health expenditures, and urbanization trends.
Population growth is driven by birth rates exceeding death rates. While birth rates are high in developing countries, death rates have declined globally due to improved healthcare. The world population grew rapidly in the late 20th century and is projected to reach over 8 billion by 2028 and 10 billion after 2200. Population growth will be concentrated in developing regions, with Asia and Africa seeing substantial increases. Rapid urbanization and increased migration are also emerging trends with impacts on business and the environment like water scarcity and habitat destruction.
The document discusses population demographics in Pakistan. It defines population as a group of organisms of the same species living in the same area, and demography as the study of human populations in terms of size, composition, distribution, and how populations change over time through births, deaths, and migration. It provides statistics on Pakistan's current population size, population growth rates, birth and death rates, ethnic and religious composition, languages spoken, literacy rates, education expenditures, health expenditures, and urbanization rates. In summary, the document analyzes key population statistics and demographics of Pakistan.

Rapid population growth and high fertility rates are linked to higher poverty levels.
This document provides demographic details about the world population and Pakistan. It defines demography and notes that the world population reached 7 billion in 2011. It then summarizes population growth trends in Pakistan, including that Pakistan has a population of over 187 million as of 2011. Several key demographic statistics about Pakistan are presented, such as population density, birth and death rates, urbanization rates, gender ratios, and literacy rates.
India's population has grown significantly over the past century and is projected to surpass China's population by 2050. Key points:
- India's population doubled from 361 million in 1951 to 846 million in 1991 and reached over 1.2 billion in 2011.
- The population growth rate has declined but population continues to rise rapidly due to the large youth population.
- India's age structure is characterized by a broad base and tapering top on age pyramids, indicative of developing countries with high birth rates.
- Sex ratios in India have historically been unfavorable to women and declined further over time, indicating a preference for male children.
This document outlines the course content and first chapter for the course Development Economics II. The course is 3 credit hours, taught by instructor Yerosan S.B., and covers topics like population growth, human capital, agriculture, trade, and foreign aid. The first chapter discusses population growth and its measurement, the relationship between population growth and economic development, and concepts like fertility rates, mortality rates, and age distribution. It also covers the demographic transition experienced by developed countries as mortality declined before fertility, leading to population growth.
India has experienced rapid population growth in recent decades. The population reached over 1.21 billion according to the 2011 census, making India the second most populous country. Population growth is driven by a historical high birth rate and declining death rate. This rapid growth creates challenges for development by increasing demand for resources. Efforts are needed to reduce population growth through expanding education and employment, especially for women, as well as improving public health, access to family planning services, and social security for the elderly.
Chapter 5: Hidden Momentum of Population Growth in India jstubblefield
The document summarizes key concepts from Chapter 5 on population growth in India. It discusses global population milestones from 1 billion in 1830 to 6 billion in 1999. It also covers demographic concepts like crude birth/death rates, population pyramids, and demographic transition. Specifically for India, it notes India's population growth from 1901-2000 and shifts to lower fertility rates from 1971-2000, despite continued growth due to demographic momentum.
This document outlines the course content for a class on population growth and economic development. The six main topics covered are: 1) Population growth and economic development, 2) Human capital: education and health, 3) Rural-urban interaction and unemployment, 4) Agriculture and development, 5) International trade and industrialization, and 6) Foreign aid, debt, and financial reform. The first chapter focuses on measuring population growth, its impact on development, and basic concepts like birth rate and death rate. It also discusses Thomas Malthus' theory of the population trap, where high population growth leads to diminishing resources and low standards of living.
This document discusses population genetics and defines a sexual population as a group of organisms that can interbreed to produce fertile offspring. It notes that complete panmixia, where all gametes freely interbreed, is rare in nature. Instead, populations tend to be subdivided into smaller demes or gamodemes with some limited gene flow between them. This leads to genetic variation between demes and increased homozygosity within demes over time.
This document summarizes a paper analyzing mortality variations across India. It finds that overall mortality rates declined between 1971 and 1996 censuses. Female mortality rates were consistently lower than male rates. Life expectancy increased substantially from 1970-75 to 1993-97, though rural rates remained below urban. About 36% of the population lives below the poverty line, and their mortality is likely heavier than the overall population mortality captured in census data. Assured lives mortality from insurance data is even lighter than population mortality due to selection effects excluding high-risk individuals.
This document summarizes statistics from Indonesia's Central Bureau of Statistics (BPS) on inclusive growth indicators. It notes that over 80% of the world's population lives in countries with large income disparities, with the poorest 40% only enjoying 5% of global income while the richest 20% enjoy 75% of global income. While Indonesia's economy grew 5.8% annually 2004-2012 on average, unemployment only fell by an average of 0.35 million people per year, and poverty declined by an average of 0.94 million people per year. However, economic growth alone cannot solve poverty and unemployment issues, and income inequality is increasing, questioning the quality of growth.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

The modification of an existing product or the formulation of a new product to fill a newly identified market niche or customer need are both examples of product development. This study generally developed and conducted the formulation of aramang baked products enriched with malunggay conducted by the researchers. Specifically, it answered the acceptability level in terms of taste, texture, flavor, odor, and color also the overall acceptability of enriched aramang baked products. The study used the frequency distribution for evaluators to determine the acceptability of enriched aramang baked products enriched with malunggay. As per sensory evaluation conducted by the researchers, it was proven that aramang baked products enriched with malunggay was acceptable in terms of Odor, Taste, Flavor, Color, and Texture. Based on the results of sensory evaluation of enriched aramang baked products proven that three (3) treatments were all highly acceptable in terms of variable Odor, Taste, Flavor, Color and Textures conducted by the researchers.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
