This pattern is most often observed in underdeveloped countries where individuals do not live to old age because of less-than-optimal living conditions. Countries with rapid growth have a pyramidal shape in their age structure diagrams, showing a preponderance of younger individuals, many of whom are of reproductive age or will be soon ( ). Age structure allows better prediction of population growth, plus the ability to associate this growth with the level of economic development in the region. Age structure is the proportion of a population at different age ranges. The age structure of a population is an important factor in population dynamics. Age Structure, Population Growth, and Economic Development Thus, it appears that the influence of infectious disease on human population growth is becoming less significant. To compare to some of the epidemics of the past, the percentage of the world’s population killed between 19 decreased from 0.30 percent of the world’s population to 0.24 percent. According to the World Health Organization, global death from infectious disease declined from 16.4 million in 1993 to 14.7 million in 1992. Today, the threat of infectious disease, while not gone, is certainly less severe. In the past, diseases such as the bubonic plaque of the fourteenth century killed between 30 and 60 percent of Europe’s population and reduced the overall world population by as many as 100 million people. Public health, sanitation, and the use of antibiotics and vaccines have decreased the ability of infectious disease to limit human population growth. Humans originated in Africa, but have since migrated to nearly all inhabitable land on the Earth. Other factors in human population growth are migration and public health. In addition, humans use language to communicate this technology to new generations, allowing them to improve upon previous accomplishments. Humans can construct shelter to protect them from the elements and have developed agriculture and domesticated animals to increase their food supplies. Much of this ability is related to human intelligence, society, and communication. This ability is a major factor responsible for human population growth and a way of overcoming density-dependent growth regulation. ![]() Humans are unique in their ability to alter their environment with the conscious purpose of increasing its carrying capacity. In spite of this fact, human population is still growing exponentially.Ĭlick through this interactive view of how human populations have changed over time. Also, resources would have to be such that the environment would support such growth. To reach its biotic potential, all females would have to become pregnant every nine months or so during their reproductive years. The world’s human population is currently experiencing exponential growth even though human reproduction is far below its biotic potential ( ). As some point out, it is likely that the negative effects of increasing carrying capacity will outweigh the positive ones-the carrying capacity of the world for human beings might actually decrease. The ultimate effect of these changes on our carrying capacity is unknown. The depletion of the ozone layer, erosion due to acid rain, and damage from global climate change are caused by human activities. ![]() Earth’s human population is growing rapidly, to the extent that some worry about the ability of the earth’s environment to sustain this population, as long-term exponential growth carries the potential risks of famine, disease, and large-scale death.Īlthough humans have increased the carrying capacity of their environment, the technologies used to achieve this transformation have caused unprecedented changes to Earth’s environment, altering ecosystems to the point where some may be in danger of collapse. Humans, however, have the ability to alter their environment to increase its carrying capacity sometimes to the detriment of other species (e.g., via artificial selection for crops that have a higher yield). For example, beaver dams alter the stream environment where they are built. Humans are not unique in their ability to alter their environment.

![]() Using V = 1100ft/sec the equations simplifies toĤ000rpm peak boost requires 33" tubes!! That length includes the ports in the heads. For cool intake air it is about 1100ft/sec Values of 1300ft/sec to 1700 ft/sec are common. L = pipe length, less port length in head, in inches Thus tuning length is very easy to determine once you have an estimate of the speed of sound in the hot gasses (or cold gasses for intakes). Other pulses from other header tubes are of much smaller magnitude in the tube of interest and can be ignored. You want this positive pressure pulse to reach the intake valve the instant it closes to supercharge the cylinder. Obviously, the opposite is true for intake manifolds - the opening intake valve causes a negative pressure pulse to travel up the intake runner and a positive pulse is reflected back down the tube. The main advantage gained in equal length, independent primary header tubes is from the strong negative pressure pulse that is reflected from the tube end when the strong positive pressure pulse from the exhaust valve reaches the collector. Injector stacks have an infinite 'plenum' - the atmosphere!) is reasonably larger than the primary tubes, each tube acts independently from its neighbors. Read these old threads.Īssuming the (exhaust) collector size (or carb plenum. If any of you have input on this, I would appreciate it greatly. But I'm curious to know what you all think. My engine guy says to make them the same length as the ones that came from Hilborn. I'm guessing that the optimum velocity stack length varies by application, and the only way to know what's best is by trial and error on the dyno. ![]() Not sure on the cam specs, or if any of this info is relevant. The engine is limited to 6250 RPM, and will rarely if ever see more than 4500 RPM. Now, I'm making custom curved velocity stacks, and I'm wondering if I'd gain anything by making them a little longer. My engine builder said that when the previous stacks were cut-down from their stock length to fit under the hood, we threw away 40 ft-lbs of torque. I'm looking for opinions regarding the optimum length for a Hilborn EFI fuel injector velocity stack. ![]() HMD recognizes that rigorous documentation of fabrication records is an indivisible component of nuclear hardware. Likewise, the implementation of the Corrective Action Request (CAR) process has been lauded by visiting auditors and invigilators as a state-of-the-art process. The control of the manufacturing processes by the indigenously developed “e-sads” package has eliminated virtually all errors arising from human performance failings. This information management system also permits HMD to document and process all deviations – big and small – in accordance with the company’s written quality assurance procedures. The machinery, fixtures, tools, and equipment that comprise HMD’s physical infrastructure are supported by a state-of-the-art information management system that enables the factory to produce nuclear grade hardware with a rigorous and detailed record of the critical inspection and fabrication evolutions for archival reference. ![]() Operating processes and procedures are continually verified to meet the most stringent requirements of HMD’s customers. HMD uses a broad range of quality-certified engineering and manufacturing processes that include computer-aided design, precision machining and welding, and performance testing.

While the great bulk of HMD’s manufacturing output is based on Holtec Nuclear Division’s engineered designs, and is largely of safety-significant pedigree, HMD also manufactures commercial heat exchange equipment and weldments for the Heat Transfer Division. The organizational independence of QA from production is an important element of Holtec’s corporate organization. The Quality personnel are direct employees of Holtec International, while the production personnel are on HMD’s payroll. To establish complete independence between production and quality, HMD’s quality group reports directly to the corporate Quality Assurance Vice President, based on New Jersey. State-of-the-art manufacturing machinery supported by a cutting-edge information management system constitutes the manufacturing infrastructure of the company which produces hundreds of complex capital equipment each year to the exacting codes and standards involved in their purchase specifications.Īnother major operational link between the factory and the headquarters is Quality Assurance. HMD has differentiated itself as a distinguished manufacturer for discerning clients by a total commitment to nuclear quality, by maintaining a first-rate manufacturing infrastructure and by a vigorous program of developing and nurturing high quality craftsmanship. Over 80% of HMD’s manufactured equipment are destined for commercial nuclear plants. In addition, the factory is served by a proven array of subcontractors who provide a multitude of services ranging from laboratory testing services to laser metal cutting. Nondestructive testing capabilities include the entire gamut of methods used in the metal fabrication industry, such as liquid penetrant, magnetic particle, radiographic, helium leak, hydrostatic, ultrasonic, load and functional testing. ![]() HMD employs the latest technology in water jet cutting, laser cutting, grit blast and painting in an environmentally controlled autonomous in-shop paint facility.

Part II : Build the foundation in Softr.io It will help you build your own secure Airtable database. Here is the link to the demo Airtable base : In addition, if you make some change in the table “Private User Database”, thanks to the look-up all updates would be handled automatically by Airtable in the “Public User Database”.Consequently, when a new record is created in your private table, a new record is created in the public table. ![]() The following action, based on this condition set up previously, would create a new record in Public User Database.The condition has to be triggered from the “Private User Database”. There, you have to define a trigger, regarding our case we have to use the following trigger : “When record created”.In order to do this, go to the Automation section. First, you need to create an automation within Airtable.Step 4: Add automatically a new line in the private user database and duplicate it to the public table ? Therefore, just select the database and then select the table with non-sensitive user data in this case “Public User Database” and set up all the fields required. Once done, you can add a block “list” to your application. In this example, we will make lookups on the “Last Name” and “First Name” fields, which are considered as non-sensitive data.We are going to look-up information from our database table ”Private User Database” to the new table “Public User Database”. Create a first lookup based on the “Link to another record” field created before.Create a “Link to another record” field.Delete all the columns created by default by Airtable.We will call this table “Public User Database”. Create a second table in the same user database.This table will be connected to Softr.io, as there is no sensitive data, this is why we are calling it “Public User Database” and creating a “Link to another record” field. To continue, building a second table is required before creating the Softr.io application. Step 2: Build the table “Public User Database” “Address”, Field Used: Single line text.“First name”, Field Used: Single line text.“Last Name”, Field Used: Single line text. ![]() Let’s start by adding some user information.Transform the first column from the field “single line text” to an “Autonumber” field.Delete all the columns created by default by Airtable.Inside of this database create a private user database table called “Private User Database”. ![]() This table will never be directly linked to Softr.io.
