Sharks have a ventral mouth opening with serrated teeth that can operate simultaneously or be gradually replaced. Their gastrointestinal tract includes a stomach and spiral intestine, and they lack salivary glands but have a well-developed liver and pancreas. Sharks have 5-7 pairs of gill slits on the sides of their pharynx and large olfactory lobes and cerebellum in their brain. Their skin has sensory buttons and taste buds in their oral cavity. Sharks have two-chambered hearts and use their gills to breathe by taking in water and releasing it, exchanging oxygen and carbon dioxide in their blood which is then distributed throughout their body.

O documento discute as influências bucólicas e virgilianas no trabalho de Eça de Queiroz, especialmente em "A cidade e as serras". Três temas principais são explorados: 1) A reação contra o decadentismo de Huysmans e a recuperação de Virgílio, 2) Os usos do bucolismo virgiliano em termos de amizade, liberdade, fortuna, imediatez e paisagem, 3) A leitura regeneracionista de Virgílio em contraste com a de Proudhon.
El documento presenta dos problemas estadísticos. El primero pide calcular valores de probabilidad para una variable aleatoria con 10 grados de libertad y valores mayores o menores que ciertos límites. El segundo pide calcular probabilidades para una distribución ji cuadrada con diferentes grados de libertad y valores límite, y graficar cada caso.
The document summarizes French society and economic conditions prior to the French Revolution. It describes the hierarchical social structure with the King and aristocrats at the top and peasants at the bottom. Peasants lived difficult lives with little land or wealth. Cities like Paris were overcrowded and many residents lived in poverty. The growing middle class, or bourgeoisie, faced laws and regulations that hindered business growth. When Louis XVI assumed the throne in 1774, he inherited a country with economic struggles including unemployment and food shortages, fueling discontent among the people.

U četvrtak, 14. svibnja, u dvorani 14 Ekonomskog fakulteta u Zagrebu, Financijski klub održao je posljednju konferenciju akademske godine 2014./14. – Student investitor 2015. Konferencija se održava već 6. godinu zaredom te služi kao prilika studentima da se upoznaju s aktualnim financijskim i investicijskim domaćim i svjetskim trendovima te da članovi Financijskog kluba predstave svoj rad tijekom protekle godine.
Overwinter transformation and fate of fall applied manure nitrogenLPE Learning Center
The full proceedings paper is at: www.extension.org/72749
There is growing evidence that soil nutrient cycling is sustained during the non-growing season in the northern regions of Canada. However, the extent of the transformations and loss of fall-applied manure N is not well documented. The NH4-N fraction of liquid dairy cattle manure, liquid swine manure, and ammonium sulfate was enriched with 15N radioactive isotope, and all N sources were applied to bare sandy loams in early November at sites located in contrasted climate (mean annual temperature 1 to 10°C; mean annual precipitation 300 to 1300 mm; mean snow cover depth <5 to 70 cm). The experiment was replicated over two years at each site. Soils were sampled on the week of application, in November, and at intervals until next May. The recovery of applied 15N in soil NH4-N, NO3-N and organic N pools was measured in the 0-30 cm depth. Soil temperature was also monitored at the 5, 20 and 50 cm depths. Although the transformation of applied ammonium was delayed in colder areas, the transformation of 15NH4-N was generally completed by April, generally before seeding of the next crop. Both nitrification and immobilization of fall-applied 15NH4-N occurred throughout the non-growing season at all sites. As a result, residual 15N was essentially recovered as NO3-N and organic N in the following spring. In most cases, more than 50% of fall-applied 15N was not recovered in the following spring. In general, more 15NH4-N was immobilized with manures than ammonium sulfate, possibly because of the presence of fresh carbon in the manure. As a result, more 15N was recovered in the spring with the manure, and this was particularly obvious at the warmer sites. We conclude that a significant portion of fall-applied NH4-N may be lost during the non-growing season, even in areas with cold and long winter period.
