Photovoltaic (PV) cells convert sunlight into electric power and were invented in 1954 at Bell Labs. Mass production of PV cells began in the 1960s, lowering the cost per watt from $1000 to $3 by 2010. Designing and sizing an effective PV system requires calculating the predicted annual power distribution using tools like the National Renewable Energy Laboratory's PV Watts Calculator, which determines a system's energy production and cost savings. The environmental impact of a PV system can also be estimated using calculators available from the Environmental Protection Agency based on the system's energy production.

The COCOMO model is a widely used software cost estimation model developed by Barry Boehm in 1981. It predicts effort, schedule, and staffing needs based on project size and characteristics. The Basic COCOMO model uses three development modes (Organic, Semidetached, Embedded) and a formula to estimate effort and schedule based on thousands of delivered source instructions. However, its accuracy is limited as it does not account for various project attributes. Function Point Analysis is an alternative size measurement that counts types of system functions to estimate effort and cost based on a project's adjusted function points.

The document discusses quality assurance and ISO 9001 standards. It outlines the main features of ISO 9001:2000 which include a process approach, measurement, management, customer satisfaction monitoring and continual improvement. ISO 9001:2000 emphasizes quality management distinct from quality assurance, control and requirements. Quality assurance is important in construction to avoid defects which can cause serious problems or fatalities. Following steps in construction help achieve quality assurance: defining requirements, planning, material testing, and quality control during construction.
Jesus explica a Nicodemos que é necessário "nascer de novo" para entrar no Reino de Deus, referindo-se à doutrina da reencarnação. A encarnação permite que as almas progridam através de sucessivas vidas, aprendendo com experiências e se aproximando da perfeição. A reencarnação é a única explicação para as diferenças entre os seres humanos e a justiça divina nas desigualdades da vida.
1. O capítulo discute como o Espiritismo cumpre a promessa de Jesus de enviar o Consolador;
2. O Espiritismo esclarece ensinamentos de Jesus que as pessoas da época não podiam compreender completamente;
3. A doutrina espírita traz consolo ao explicar as causas do sofrimento humano e a justiça divina.
No período pré-histórico, os humanos comiam frutos, raízes e ovos de animais, e aprenderam a melhorar sua alimentação com o fogo. Durante a era dos descobrimentos, os portugueses comiam cereais, peixe seco e bacalhau. A partir do século XIX, a Revolução Industrial modificou os hábitos alimentares com o desenvolvimento da indústria alimentar e as mulheres trabalhando fora de casa.
O texto é uma reflexão sobre a importância de aproveitar cada momento com entes queridos e expressar o amor diariamente, já que o futuro é incerto. Ele incentiva a abraçar e dizer "eu te amo" aos outros hoje, pois o amanhã não é prometido e podemos nos arrepender se perdermos uma última chance.

Momentum is a measure of how difficult it is to stop a moving object. It is defined by the equation momentum (p) equals mass (m) times velocity (v). In a closed system where no external forces act, the total momentum before an event like a collision will equal the total momentum after the event, according to the principle of conservation of momentum.
Coronary heart disease narrows arteries which reduces blood flow, straining the heart. A stent opens blocked arteries to restore blood flow. Statins lower cholesterol to prevent further blockages. A faulty heart valve causes problems by not opening/closing properly, requiring valve replacement or repair. A heart transplant may be needed for severe damage while an artificial heart provides temporary support until transplant. Treatments include stents, statins, valve procedures, and transplants.
Evaluating treatment methods for cardiovascular diseaseTeresa Middleton
Cardiovascular disease is a leading cause of death worldwide. Researchers conducted a study to evaluate different treatment methods for cardiovascular disease. The study found that exercise and diet modifications were effective at reducing the risks associated with cardiovascular disease and had fewer side effects than pharmaceutical treatments.
This document provides learning objectives about coronary heart disease, including describing how arteries narrow, explaining the impacts of narrowing arteries, explaining how stents and statins work, understanding faulty heart valves and related problems, and knowing treatments for cardiovascular disease such as transplants and artificial hearts.
The document provides information about the human digestive system and enzymes. It discusses how the digestive system breaks down large food molecules, the sites where digestive enzymes are produced, and the specific enzymes involved in digesting carbohydrates, proteins and lipids. It also addresses how enzymes work using the lock and key model, and factors that affect enzyme activity such as temperature and pH.
The document discusses the structure and function of the heart, lungs, and blood vessels. It states that the heart is a muscle that acts as a double pump, with the right ventricle pumping blood to the lungs and the left ventricle pumping it around the body. It also mentions key blood vessels associated with the heart. The lungs function to facilitate gas exchange, while the three types of blood vessels - arteries, veins, and capillaries - have different structures suited to their roles in circulating blood and transporting gases and nutrients.

Power is defined as the rate at which energy is transferred or work is done. It is measured in watts and calculated by multiplying either the energy transferred in joules by time in seconds, or the work done in joules by time in seconds. An energy transfer of 1 joule per second equals a power of 1 watt. Students should be able to give examples comparing systems that transfer the same amount of energy or do the same amount of work but over different periods of time to illustrate differences in power.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
