The Production of Bioethanol Fermentation Substrate from Eucheuma cottonii Seaweed through Hydrolysis by Cellulose Enzyme

AbstractThe aim of this research was to produce high reduction sugar component of bioethanol fermentation substrate using E. cottonii seaweed. The dried E. cottonii was taken from Buton district, South East Sulawesi. The seaweed was hydrolyzed using cellulose for 24hours with various enzyme concentrations (19, 36, and 52 AU) and temperatures (40 and 50°C). The reduction sugar was analyzed by Nelson-Somogy Method then statistical significance test (t-test) was processed by using SPSS software. The results showed that the reduction sugar was 8.045mg/mL, obtained during 12hours of hydrolysis process using 36 AU cellulose at 50°C. However, this hydrolysis result was not significantly different (tested by t-test analysis) with the result shown by 19 AU cellulose enzyme hydrolysis at 50°C temperature which produce 7.937mg/mL of reduction sugar component

Beyond cute: exploring user types and design opportunities of virtual reality pet games

Virtual pet games, such as handheld games like Tamagotchi or video games like Petz, provide players with artificial pet companions or entertaining pet-raising simulations. Prior research has found that virtual pets have the potential to promote learning, collaboration, and empathy among users. While virtual reality (VR) has become an increasingly popular game medium, litle is known about users' expectations regarding game avatars, gameplay, and environments for VR-enabled pet games. We surveyed 780 respondents in an online survey and interviewed 30 participants to understand users' motivation, preferences, and game behavior in pet games played on various medium, and their expectations for VR pet games. Based on our findings, we generated three user types that reflect users' preferences and gameplay styles in VR pet games. We use these types to highlight key design opportunities and recommendations for VR pet games

Cómo demostrar en matemáticas

En su libro sobre la teoría de conjuntos y la hipótesis del continuo, Paul J. Cohen (COHEN 1966, p2) se refiere a Brouwer en las siguientes palabras: " ... la escuela de Brouwer (lntuicionismo) sólo admitiría conjuntos finitos como objetos legítimos de estudio, y aún un número entero solo no se consideraría definido a menos que se diese una regla absolutamente determinada para computarlo (Por ejemplo, el conjunto cuyo elemento es 5 si el último Teorema de Fermat es verdadero y si es falso, no está bien definido de acuerdo con Brouwer)". No habría estado bien definido porque no se podía afirmar que el teorema de Fermat fuese verdadero ni que fuese falso. Lo de Brouwer tiene muchos años, aunque, como se sabe, es de nuestro siglo, pero lo de Cohen es de 1966. Veintinueve años más tarde, el enunciado de Brouwer ha cambiado de sentido

Computar y compactar

El trabajo se refiere principalmente a los programas elaborados por Chaitin para computar con una máquina universal de Turing y a cómo puede mostrarse que el número omega de Chaitin (elaborado sobre la base de la probabilidad de la detención de un pro• grama) es absolutamente incomputable. Se trataría de una entidad matemática definible pero no compactable (en el sentido de compresible), y que se puede comparar con un enunciado a la Godel, verdadero pero indemostrable

Gendered Paths to Formal and Informal Resources in Post-Disaster Development in the Ecuadorian Andes

The devastating eruptions of Mount Tungurahua in the Ecuadorian highlands in 1999 and 2006 left many communities struggling to rebuild their homes and others permanently displaced to settlements built by state and nongovernmental organizations. For several years afterward, households diversified their economic strategies to compensate for losses, communities organized to promote local development, and the state and nongovernmental organizations sponsored many economic recovery programs in the affected communities. Our study examined the ways in which gender and gender roles were associated with different levels and paths of access to scarce resources in these communities. Specifically, this article contrasts the experiences of men and women in accessing household necessities and project assistance through formal institutions and informal networks. We found that women and men used different types of informal social support networks, with men receiving significantly more material, emotional, and informational support than women. We also found that men and women experienced different challenges and advantages when pursuing support through local and extralocal institutions and that these institutions often coordinated in ways that reified their biases. We present a methodology that is replicable in a wide variety of disaster, resettlement, and development settings, and we advocate an inductive, evidence-based approach to policy, built upon an understanding of local gender, class, and ethnic dynamics affecting access to formal and informal resources. This evidence should be used to build more robust local institutions that can resist wider social and cultural pressures for male dominance and gendered exclusion

Uterine natural killer cells and successful pregnancy:from mouse experiments to human physiology

Uterine natural killer (uNK) cells, a specific type of natural killer (NK) cells, are important cells at the foeto-maternal interface in humans as well as in mice. uNK cells are part of the innate lymphoid cells group 1. Especially in the mouse, but also in the rat, many in vivo studies have been performed to evaluate the role of uNK cells in placental development. These studies have shown that uNK cells are not indispensable to pregnancy, but that they play an important role in optimal decidual angiogenesis in early pregnancy, trophoblast invasion and spiral artery remodelling in the mouse placenta. Based on the mouse studies, various in vitro studies, as well as immunohistological studies of the human placenta from elective abortions, have shown that uNK cells have similar functions in the human placenta. In the present narrative review, the role of the uNK cells in the development of the mouse and rat placenta will be discussed first. Thereafter, studies on the role of human uNK cells in the human placenta will be reviewed and these studies will be discussed in the light of the knowledge on mouse uNK cells
