Neanderthal Subsistence Strategies and Implications of Cognition Complexity -...
A presentation that was given in 6 minutes on Neanderthal Cognition. Some of the slides are just photos - feel free to contact me for the notes on the slides if you're interested in what I had to say.
Here are notes from a few slides:
Slide 6: Jonzac has a prevalent reindeer bone bed, as you can see in the image of the excavation. When these bones were analyzed, researchers found that 22% of them had butchery marks that were in the correct location to indicate skinning, dismembering, and defleshing, as well as marrow extraction. The age analysis of the skeletal remains show that it was mostly prime-age reindeer, which is an important distinction for cognition implication, since animals in their prime are harder to exploit than the juveniles or seniors. These reindeer seasonally migrated past the Jonzac rock shelter where the processed remains were found, but the remains show multiple years’ worth of use or multiple hunting trips for the site.
Slide 7: It’s hard to document human interaction with cave bears, as most of the remains are found in caves which matches the hibernation pattern of cave bears. However, there are cave bear remains in open air Paleolithic occupation sites, showing evidence of deliberate hunting. Some of the remains in the open air sites are missing the associated fauna with natural cave taphonomy, implying the remains were not scavenged from an already dead bear. Cut marks were identified on the remains and one cave bear had an embedded flint projectile in its vertebrae. These animals were massive, and would have taken a lot of individuals and communication in order to successfully utilize. In some of these sites, there is evidence of art objects, such as pendants, and bone tools made from the bones of the cave bear.
Slide 8: Using two forms of mass spectrometry, combined with morphological analysis of plant microfossils, researchers were able to identify materials trapped inside the dental calculus of five Neanderthal individuals from El Sidron, Spain. This analysis revealed the first molecular evidence of inhalation of wood-fire smoke, bitumen or oil shale, and ingestion of a range of cooked foods, specifically plants. They also found evidence of ingestion of two plants known today for their medicinal qualities. The medicinal plants discovered were bitter-tasting plants with no nutritional value. The authors also point out that the evidence for complex use of medicinal plants by primates is well-documented, so it is not unreasonable to extrapolate medicinal use of plants by Neanderthals. Bitumen was used as a hafting material by Neanderthals, and the nearest oil shale source is 15 km away from the site of Sidron.
work book
This document contains worksheets on prisms with multiple problems involving calculating surface areas and volumes of triangular, square, and cylindrical prisms. There are 4 problems in each of 3 activities - calculating surface area of triangular prisms with given dimensions, volume of triangular and trapezoidal prisms, and volumes of cylinders that can be carved from prisms or formed by rolling rectangular sheets. The document provides the questions and spaces for answers but no solutions shown.
Focus group q's
This focus group document contains 10 questions to ask participants about a music magazine, including whether the front cover, contents page, and spreads seem cohesive; what information on the front cover looks interesting; who the magazine seems targeted towards in terms of gender or ethnicity; what language is interesting to read; what aspects catch the eye on the front cover; opinions on the color scheme; what music genre the magazine represents; whether the magazine appeals to the participant; and whether they would want to read the next issue.

On criteria for occurence of azeotropes in isothermal and isobraric binary sy...Josemar Pereira da Silva
The document discusses criteria for predicting the occurrence of azeotropes in binary systems under isothermal and isobaric conditions.
For isothermal systems, the criteria are expressed in terms of the activity coefficients at infinite dilution (γ∞). For a positive azeotrope, γ∞ of the less volatile component must be greater than or equal to the ratio of the saturation vapor pressures. For a negative azeotrope, γ∞ of the more volatile component must be less than or equal to the inverse of the ratio.
For isobaric systems, the criteria involve γ∞ evaluated at the boiling points. For a minimum-boiling azeotropeLegionella pneumonia
Legionnaires' disease was first recognized in 1976 after an outbreak in Philadelphia. It is caused by Legionella bacteria found in water sources, with L. pneumophila being the most common cause. Symptoms include pneumonia and fever. Risk factors include older age, smoking, and weakened immunity. Diagnosis involves urine antigen testing or culture from respiratory samples. Treatment involves antibiotics like fluoroquinolones or azithromycin. Prevention focuses on disinfecting water systems in buildings where outbreaks occur.

Location recce
The photographer chose a photography studio as the location for their shoot because studios are commonly used in magazines and provide a professional look. Shooting in a studio also allows for easier editing and manipulation of images compared to outdoor locations. Most magazines use plain backgrounds in the studio so the subject is the main focus of the photo.
Q&a article
Eva was interviewed about her career in rock music. She grew up surrounded by rock music like AC/DC and Queen, which inspired her to pursue a career in rock. Over the past year, she has had a hectic schedule but is grateful for her success. When she was nominated for 3 Brit Awards and won Best New Artist, she was shocked and felt overwhelmed with love and gratitude. She is happy that rock music is being appreciated by more people today. Fans can look forward to seeing Eva and her band very soon as they have exciting new things planned.
Planning dps
The document discusses different types of music magazine articles - free flowing articles and Q&A style articles. Free flowing articles require the writer to describe scenes and express opinions to set an atmosphere, while Q&As are easier to create by simply writing questions and answers. After analyzing examples of each style, the conclusion is that a free flowing article would allow more creative expression, but a Q&A is good for getting specific information from an artist and is interesting for readers. The decision is made to produce a free flowing article to take advantage of the more open format.
Questions for focus group about documentary
The document provides 10 questions for a focus group about a documentary they watched, asking about the opening, title, use of background footage, how informative it was, their favorite part, how interesting and realistic they found it on a scale of 1-10, if it fairly represented younger and older generations, if the music fit well, and if they came to a conclusion about today's stressed teenagers from watching.

Questionnaire radio draft
The document is a 12 question survey about a radio trailer for a documentary. It asks the respondent about their age, opinions on the length and audio clips in the trailer, how they felt about the music and pacing, who the trailer seems aimed at, and how the trailer and survey could be improved. The respondent is asked to circle their answers for closed questions and provide written feedback for open-ended questions at the end.
Legionella
This document discusses Legionella, the bacteria that causes Legionnaire's disease. It was first identified following an outbreak of pneumonia among attendees of an American Legion convention in 1976. Legionella pneumophila is the primary causative agent. The bacteria lives in water and spreads through inhalation of contaminated water droplets. It is a gram-negative bacillus that stains poorly and grows slowly in culture. Diagnosis involves detecting the bacteria or antibodies in sputum, BAL fluid, or biopsy samples through microscopy, culture, antigen detection or serology. Erythromycin is the treatment of choice with rifampin or ciprofloxacin as alternatives. Prevention focuses on heating water systems above 60°C or chlorinating to
