The document discusses how various media technologies were used at different stages of a project. A blog was used to store and document all work from initial planning through to evaluation. Online research was conducted to find existing similar products and influence design decisions. Digital cameras and video were used to capture footage and photos for ads. Adobe software like Photoshop and Premier Pro allowed for editing of visuals and videos. Social media like Facebook was used to share ads and gather feedback from target audiences. YouTube and SoundCloud hosted finished ads and audio content for feedback.

If you are looking to get tuning and or ecu re mapping for your Ferrari car, then paramount-performance is the place to be. Established since over 20 years in this industry, they are one of the most trusted names in UK.
This document discusses several image editing effects including Black & White, 3D Button, Oil Paint, and Pixilize effects that can be applied in image editing software to alter the appearance of photos. Negative effects are also listed but no details are provided about what they involve. The document is brief and lists the effect names without descriptions of how each one transforms images.
This document contains advice for planning and leading large meetings and conferences. It discusses 10 truths for making big meetings impactful. The truths include delegating tasks properly, controlling internal communication, involving attendees, being transparent, adding elements of playfulness, securing an appropriate venue, focusing on process not just content, and acting as a thought leader. The overall message is that meetings require bold, engaging leadership focused more on participation than presentations to inspire change.
The document contains a log of device plug-off events recorded between October 26, 2013 and November 7, 2013. It lists the date, time, and device identification codes for multiple devices that were unplugged or disconnected during that time period.
This document discusses the relationship between organizations and information systems. It notes that information systems are built by managers to serve business interests but organizations must also adapt to new technologies. The document then outlines several learning objectives related to using models like Porter's competitive forces and the value chain to help businesses identify strategic IS opportunities. It also discusses how IS can help achieve competitive advantages through operational excellence, new products/services, customer intimacy, improved decision-making, and survival.
This document provides instructions for an art activity called "Complete the Picture" where students are given half of an image and must draw the other half. They are to use materials like paper, crayons, and markers to draw the missing half of the chosen image. When finished, students can email their drawing to be assessed based on criteria like the appropriate use of lines, shapes, accuracy, following instructions, contrast, and overall presentation.
Anne Frank received a diary for her birthday on June 13, 1943. She wrote in the diary about longing for the war to end as bombs and gunshots could be constantly heard outside. Anne and her family were hiding from the Nazis in a secret annex, as they would be killed if discovered due to being Jewish. Anne describes how her family fled Germany after Hitler rose to power and came to the Netherlands, but were now in hiding again due to Nazi persecution of Jews.

Kapitel 16: Intermolekylära krafter och vätskor
16-11 intermolekylära krafter verkar mellan olika molekyler och inte inom samma
molekyl, dipolkrafter verkar mellan polära molekyler och är elektrostatiska till sin
natur (den positive delen i en polär molekyl attraheras till den negativa delen i en
annan polär molekyl), vätebindningar är en stark dipolkraft.
16-17 a) H2NCH2CH2NH2 eftersom den har större möjlighet att bilda vätebindningar
b) H2CO eftersom den är polär till skillnad från CH3CH3
c) CH3OH eftersom den kan bilda vätebindningar
d) HF eftersom den kan bilda vätebindningar (H bundet till F som är mer
elektronegativ än Br)

eftersom fast fas-vätskelinjen lutar år höger med en positiv lutning så har den
fasta fasen en högre densitet.

Reaktionsblandningen skall kylas eftersom reaktionen är exoterm. Risken annars
är att den blir så varm att H2SO4(aq) börjar koka
Detta är en endoermisk reaktion så att värme måste tillföras för att bilda
produkten. Värmeutvecklingen i motorn förser ger värmen.
