- The document analyzes recent evidence that human evolution through positive selection has accelerated greatly in the last 40,000 years, especially since the development of agriculture 10,000 years ago.
- Using data from the HapMap project, the authors estimate selection rates and allele ages that indicate much more rapid adaptation than would be expected from a constant selection rate over human history.
- However, a constant high rate of adaptation is inconsistent with observed levels of human genetic diversity and the number of amino acid changes between humans and chimpanzees. The evidence supports a model where increasing human population size has accelerated the rate of adaptive evolution.
The document discusses the increasing focus on sustainability in the agri-food sector. Major companies like Unilever have announced ambitious sustainability goals to cut CO2 emissions, water use, and waste production in half over the next decade while doubling revenue. Sustainability has become a competitive advantage as consumers increasingly demand more sustainable options. Though the concept of sustainability has existed since the 1980s, high-profile events like Al Gore's documentary An Inconvenient Truth brought greater attention to issues like climate change in recent years, driving more action from companies. NGOs also play a role in improving sustainability in food chains by advocating for issues and running pilot projects.

This document discusses cell perforation using pulsed electric fields (PEF) to preserve fresh juice. It notes that microbes are naturally present in fresh juice and can exponentially grow, potentially causing foodborne illness outbreaks. The document then explains that applying a pulsed electric field to the juice using PEF technology creates an electric field distribution that perforates microbe cell membranes, immediately eliminating their viability. The result is healthy juice with an extended shelf-life of 21-60 days without refrigeration.

This study compared the effects of pulsed electric field (PEF) processing and high-temperature short-time (HTST) thermal pasteurization on the shelf life and quality attributes of apple juice. Apple juice treated with both methods was analyzed for microbial growth and quality changes over 168 days of storage. PEF processing was less effective at reducing microbial counts compared to HTST, but maintained better color and sensory qualities closer to fresh juice. While HTST provided greater microbial safety, PEF processing has potential as a non-thermal alternative for maintaining nutritional and sensory qualities of fruit juices if further design improvements can enhance its microbial inactivation effectiveness to meet food safety standards.
This document discusses electrode material migration during pulsed electric field (PEF) treatment of foods. It provides background on how PEF treatment works to inactivate microbes while retaining food quality, but can also lead to undesirable electrochemical reactions and migration of metals from electrodes into the food. The document describes previous research that has studied this problem and suggested ways to control it, such as through pulse parameters and electrode material selection. It then outlines an experimental setup and samples that will be used to further investigate the effect of pulse characteristics and solution pH on electrode material migration in aqueous solutions.

The report summarizes Metabolic Lab's work in developing a technical plan to achieve sustainability goals at two development sites in Amsterdam - a floating residential community called Schoonschip, and an adjacent office park called de Ceuvel. The plan aims to make the sites self-sufficient in energy, water, waste processing, and food production through combining technologies like renewable energy, water treatment, urban agriculture, and more. It provides flexible toolkit of options that residents can choose from based on their needs and budgets. The overall goal is for the sites to serve as an example for more sustainable urban development.

Steve Jobs deu um discurso para os formandos de Stanford onde compartilhou três histórias de sua vida: 1) Como largou a faculdade e isso o levou a descobertas valiosas, 2) Como foi demitido da Apple e isso o levou a criar novas companhias de sucesso, 3) Sobre receber um diagnóstico de c?ncer terminal e como isso o fez apreciar a vida. Ele encorajou os formandos a seguirem seus sonhos e cora??es.
El documento discute las ventajas y desventajas del aprendizaje en línea. Entre las ventajas se mencionan la creatividad, el aprovechamiento de recursos, la interdisciplinariedad y la habilidad para buscar información. Las desventajas incluyen la necesidad de capacitación continua, la distracción y saturación de información, y el sentimiento de agobio al olvidarse del mundo real.
Este documento presenta el plan de secuencia de una asignatura de Espa?ol para el segundo grado de secundaria. La secuencia se centra en analizar cómo se presentan las noticias en diferentes medios a través del seguimiento de una noticia. La primera sesión incluye leer y analizar las características y tipos de noticias usando la técnica del "árbol de ideas", y escribir una retroalimentación sobre la actividad. El objetivo es que los estudiantes interpreten noticias de diferentes fuentes, realicen el seguimiento de una
Este documento describe la función de la capa de enlace de datos en el modelo OSI. La capa de enlace de datos prepara los paquetes de la capa de red para su transmisión a través de diferentes medios físicos mediante la encapsulación en tramas y el control del acceso a los medios. Explica cómo la capa de enlace de datos permite que los protocolos de capa superior accedan a los medios de forma independiente del tipo de medio, aislándolos de los detalles de la transición entre medios.

Este documento habla sobre las extensiones de archivos en sistemas operativos. Explica que una extensión es una cadena de caracteres anexada al nombre de un archivo que ayuda al sistema operativo a identificar el tipo de contenido y cómo procesarlo. También menciona que las extensiones surgieron como una convención en Unix y que las extensiones comunes de Windows incluyen .exe, .dll y .bat entre otras.
