Your Future Depends on Us

I created this piece to represent my personal growth throughout the past year living through a pandemic. It has a lot to do with owning my femininity and learning the importance of women relationships. I was inspired by the topic of the week of how I envision the future and that is women and the importance of women coming to be united. I created this piece on Procreate on my iPad.https://digitalcommons.csumb.edu/hcom434_spring2021/1040/thumbnail.jp

Without Us

The subject of this piece again is what the world would look like if humans disappeared one day. I chose photographs I took that inspired me to think about this subject. It has a lot to do with overgrowth and emptiness yet still so full. I think it also exemplifies quietness and peace. I created this because I was intrigued by this topic and wanted to explore it more and show my idea of what the world would look like if humans died off. I envision and hope for the future that this can be more of a reality for the world. I assembled this on Procreate.https://digitalcommons.csumb.edu/hcom434_spring2021/1042/thumbnail.jp

What We Left Behind

The subject here is what would the world be like if humans suddenly ceased to exist. This subject fascinates me and excites me. It got me thinking about what the world would look like after humans rummaged it. This photo was taken in Monterey County. I like this representation because it is abandoned and ransacked and trashed yet the plants grow towards the building. It is a bit of a play on what we would leave behind and how it wouldn’t be left so great.https://digitalcommons.csumb.edu/hcom434_spring2021/1041/thumbnail.jp

Composition des océans des lunes de Jupiter et Saturne - Approches thermodynamique et expérimentale

The existence of subsurface aqueous oceans in Jupiter and Saturn's large icy moons, theorized in the 1970s, has been confirmed by data collected by the Voyager, Galileo and Cassini-Huygens missions. The composition of chondritic and cometary materials and the data from these missions suggest that magnesium sulfate and carbon dioxide may be major components of these extra-terrestrial oceans. In order to understand the implications of the presence of these two constituents, new experiments were carried out in the H2O-CO2 and H2O-MgSO4 systems at the high pressures (0 - 2 GPa), low temperatures (250 - 350 K) and compositions (water-rich systems) expected in the hydrospheres of Ganymede, Callisto and Titan. The results from these experiments led to the first global description of the H2O-CO2 system at these conditions. The domain of stability of the two CO2 hydrates and the solubility of CO2 in water at high pressure bring new constraints on the trapping and transfer of this volatile in large icy moons. These data now make possible the high-pressure thermodynamic modeling of the CO2-CH4 sI clathrate hydrate, a phase likely involved in the segregation of these main volatile carbon molecules throughout the hydrospheres of icy moons. The first set of data acquired to constrain the eutectic composition of the H2O-MgSO4 system at high pressures complete available density data and provide the means to understand the evolution of dense oceans within massive hydrospheres. These data support the recent hypothesis of deep oceans at the bottom of the icy mantles of large icy satellites, giving a new perspective on the evolution and dynamics of these bodies.L'existence d'océans aqueux sous les surfaces des grands satellites de glace de Jupiter et Saturne, théorisée durant les années 1970, est aujourd'hui confirmée par les données des missions Voyager, Galileo et Cassini-Huygens. La composition des matériaux chondritiques et cométaires et les données des missions spatiales érigent aujourd'hui le sulfate de magnésium et le dioxyde de carbone parmi les principaux contaminants pouvant être attendus dans ces océans extra-terrestres. Pour éclaircir les implications de la présence de ces constituants, des expériences ont été menées afin de compléter l'exploration encore partielle des systèmes H2O-CO2 et H2O-MgSO4 aux conditions de haute pression (0 - 2 GPa), de basse température (250 - 350 K) et de composition (systèmes riches en eau) attendues dans les hydrosphères de Ganymède, Callisto et Titan. Les données acquises ont permis d'établir la première description globale du système H2O-CO2 à ces conditions. Les domaines de stabilité des deux hydrates de CO2 et la solubilité du CO2 dans l'eau éclairent les mécanismes de stockage et de transfert de ce volatil dans les grands satellites de glace. Ces données ont également ouvert la voie à la modélisation thermodynamique du clathrate sI de CO2-CH4, acteur potentiel de la ségrégation du carbone volatil dans les hydrosphères des lunes. Les premières données acquises pour contraindre l'eutectique du système H2O-MgSO4 permettent d'aborder la question de l'évolution d'océans denses au sein des hydrosphères. Ces données précisent l'hypothèse récente de l'existence de domaines océaniques profonds à la base des manteaux glacés des grands satellites, offrant une nouvelle vue de leur dynamique

Biological functions at high pressure: transcriptome response of Shewanella oneidensis MR-1 to hydrostatic pressure relevant to Titan and other icy ocean worlds

High hydrostatic pressure (HHP) is a key driver of life's evolution and diversification on Earth. Icy moons such as Titan, Europa, and Enceladus harbor potentially habitable high-pressure environments within their subsurface oceans. Titan, in particular, is modeled to have subsurface ocean pressures ≥ 150 MPa, which are above the highest pressures known to support life on Earth in natural ecosystems. Piezophiles are organisms that grow optimally at pressures higher than atmospheric (0.1 MPa) pressure and have specialized adaptations to the physical constraints of high-pressure environments – up to ~110 MPa at Challenger Deep, the highest pressure deep-sea habitat explored. While non-piezophilic microorganisms have been shown to survive short exposures at Titan relevant pressures, the mechanisms of their survival under such conditions remain largely unelucidated. To better understand these mechanisms, we have conducted a study of gene expression for Shewanella oneidensis MR-1 using a high-pressure experimental culturing system. MR-1 was subjected to short-term (15 min) and long-term (2 h) HHP of 158 MPa, a value consistent with pressures expected near the top of Titan's subsurface ocean. We show that MR-1 is metabolically active in situ at HHP and is capable of viable growth following 2 h exposure to 158 MPa, with minimal pressure training beforehand. We further find that MR-1 regulates 264 genes in response to short-term HHP, the majority of which are upregulated. Adaptations include upregulation of the genes argA, argB, argC, and argF involved in arginine biosynthesis and regulation of genes involved in membrane reconfiguration. MR-1 also utilizes stress response adaptations common to other environmental extremes such as genes encoding for the cold-shock protein CspG and antioxidant defense related genes. This study suggests Titan's ocean pressures may not limit life, as microorganisms could employ adaptations akin to those demonstrated by terrestrial organisms

Woodchucks

The woodchuck (Marmota monax), a member of the squirrel family, is also known as the “ground hog” or “whistle pig.” It is closely related to other species of North American marmots. It is usually grizzled brownish gray, but white (albino) and black (melanistic) individuals can occasionally be found. The woodchuck’s compact, chunky body is supported by short strong legs. Its forefeet have long, curved claws that are well adapted for digging burrows. Its tail is short, well furred, and dark brown. Exclusion: Buried welded or woven wire fences. Single-strand electric fences. Frightening Devices: Scarecrows and other effigies. Repellents: None are registered. Toxicants: None are registered. Fumigants: Gas cartridges. Aluminum phosphide. Trapping: Live traps. No. 2 leghold traps. Conibear® traps. Shooting: Effective where legal and safe
