the nature of solution
Mixtures consist of two or more substances that retain their individual properties. A solution is a homogeneous mixture where the components are uniformly distributed at the molecular level. A solution has a solute dissolved in a solvent. The ability of a substance to dissolve, or solubility, depends on factors like the nature of the solute and solvent, temperature, and pressure. Solubility generally increases with temperature for solids and decreases with temperature for gases, and increases with pressure for gases according to Henry's Law.
Ventajas desventajas
Este documento resume las ventajas y desventajas del uso de Internet en la educación universitaria ecuatoriana. Entre las ventajas se encuentran la inmediatez de la información, la posibilidad de interactuar e intercambiar conocimientos con otros, y el acceso las 24 horas a recursos como correo electrónico y redes sociales. Algunas desventajas son la existencia de información falsa o dañina, la piratería, la distracción que puede causar a los estudiantes, y la transmisión de virus.
Internal soiling test method development
The document discusses the development of internal soiling test methods for photovoltaic modules. It describes three potential test methods: the Taber oscillating test for abrasion resistance, the dust settling test to evaluate dust accumulation, and transmission measurements using a spectrometer or pyranometer to quantify the effect of soiling on glass. Preliminary results show the Taber and dust settling tests can distinguish soiling performance of different coatings, and transmission can be accurately measured with a pyranometer at short distances from the glass. Further validation of lab tests against outdoor performance is still needed.

Design Optimization using the Latest Features in HelioScope
Design Optimization using the Latest Features in HelioScopeSandia National Laboratories: Energy & Climate: Renewables
This document discusses the latest features in HelioScope solar design software and their implications for design optimization. It outlines new performance modeling capabilities like spectral adjustment and sub-hourly calculations. Engineering process enhancements include team management, design profiles, and permitting tools. The design environment features improved stringing, AC circuit calculations, 3D modeling, and layout parameters. These updates allow for less reliance on rules of thumb and more complex, optimized designs. The product roadmap indicates expanding LiDAR, optimization incorporating financials, tracker modeling, and advanced inverter modeling.Heat and temperature
The document discusses key concepts relating to temperature and heat, including:
- Temperature is a measure of the average kinetic energy of particles in an object. When matter is heated, its atoms and molecules move faster.
- Heat flows spontaneously from warmer to cooler objects due to differences in average particle kinetic energy. The energy that transfers between objects due to a temperature difference is called heat.
- Thermal equilibrium is reached when objects come to share a common temperature, with equal average kinetic energies per particle. A thermometer measures temperature by coming into thermal equilibrium with its surroundings.

1) PVsyst introduced a new framework to simulate bifacial PV systems by modeling the additional backside irradiance from ground reflections.
2) The approach calculates direct and diffuse light reaching the ground, and the backside acceptance of scattered light using view factors.
3) Initial results for a 90 kWp shed installation in Geneva show a 4-10% bifacial gain depending on the ground albedo. Further validation with measurements is still needed.Aleksandr Vedrov_SMP Own CV (eigen CV)
