Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

sections‚ the maximum volume of the gutter will then depend on the maximum area out of the shapes’ side (flank) with respect to the 12in-wide-material piece. Thus the areas of four different shapes were found. By process of elimination‚ the optimal area for each shape was found by deriving the equations of area as well as basic geometry. The shapes used for this project were a semi-circle‚ triangle‚ square‚ and rectangle. For all four shapes we maximized the area rather than the volume because the length

In mathematics‚ the Klein bottle ([klaɪ̯n]) is a non-orientable surface‚ informally‚ a surface (a two-dimensional manifold) with no identifiable "inner" and "outer" sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two-dimensional surface with boundary‚ a Klein bottle has no boundary. (For comparison‚ a sphere is an orientable surface with no boundary.) The Klein bottle was first described in 1882 by the German mathematician

The wheelchair experiment introduced me to a world that I have never known. I have never been in a wheelchair or been affected by any form of hearing‚ visual‚ or physical disabilities. So‚ this experiment caused me to really think about how the layout of a space‚ weight of doors‚ etc. could affect someone. While using the wheelchair‚ I felt as if I was in the spotlight every time I entered a room or crossed paths with a group of individuals. People would look on as I posed in the wheelchair and give

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable

Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

The study aimed to estimate the prevalence of root surface caries in the Dakshina Kannada population. 6000 patients of both gender over 15 years of age were assessed for root surface caries based on clinical examination and structured standardized interview derived from the World Health Organization Oral Health Assessment form 2013. A total of 660 patients (11%) with gingival recession exhibited root surface caries. Males exhibited higher root surface caries 11% than females in the age group of 56 to
