Characterization of soft soil using multi-channel analysis of surface waves (MASW) and electrical resistivity method (ERM)

This thesis demonstrates the research on the soft soil characteristics using geophysical methods. The need on non-intrusive, time efficient, economic and larger volume of investigation had increased the demand of using geophysical methods for geotechnical investigation. The research concentrates on the determination of soft soil shear-wave velocity (Vs) profile using the multi-channel analysis of surface waves (MASW) and the soil stratigraphy using Electrical Resistivity Method (ERM). The soft soil Vs and stratigraphy were determined and correlated with the peat sampler and borehole data to obtain more accurate data. The research was conducted at Parit Nipah and RECESS UTHM. The Vs obtained for peat and soft clay at Parit Nipah was in the range of 29.7 to 34.9 m/s and 36.8 to 76.9 m/s respectively. While, the soft clay Vs obtained at RECESS was in the range of 64.4 to 124.0 m/s. The lower Vs obtained on peat compared to soft clay was due to the heterogeneity of peat. The soil strata obtained by ERM had good agreement with the peat sampler and borehole data. The resistivity value of peat and soft clay obtained at Parit Nipah was in the range of 47.2 to 127.7 ohm.m and 9.4 to 25.8 ohm.m correspondingly. While, at RECESS soft clay, the resistivity value was in the range of 1.0 to 4.6 ohm.m. The lower resistivity value of soft clay was governed by the amount of clay fraction which was related to cation exchange capacity (CEC). As higher CEC results in higher conductivity. The relationship obtained between the 1-D Vs and 1-D resistivity value shows that consistent value of peat Vs was followed by the slight decrease in peat resistivity value. While, drastic increase in soft clay Vs results in a significant decrease in soft clay resistivity value. This concluded that stiffness does not produce significant effect on the soil resistivity. Overall, MASW and ERM produced high quality data for subsurface investigation in larger volume with timely efficient manner and more economic

Black Struggle and The Black Lives Matter movement. An Analysis of Beloved by Toni Morrison

Beloved (1987) is Morrison's fifth novel and the work that led her to win the Literature Nobel Prize. In it, Morrison digs into the events of systematized slavery in the United States and reveals the effects and the psychological damage that this produced in the black community. The novel addresses the tragic story of a former slave, Sethe whose decision to escape the plantation did not save her from the trauma of slavery. The aim of this essay is to analyze the main themes of the novel, such as slavery and motherhood, and correlate them with the present days’ racial issue in The USA. To do this, I will give a brief introduction to the Black Lives Matter (BLM) movement, what it is, and its aims in the fight against racism. Thus, proving that Morrison’s Beloved is not a mere work of art, but it has a deep psychological component that turns it into a novel for protest.Beloved (1987) es la quinta novela de Morrison y la obra que la llevó a ganar el Premio Nobel de Literatura. En ella, Morrison indaga en los acontecimientos de la esclavitud sistematizada en Estados Unidos y revela los efectos y el daño psicológico que ésta produjo en la comunidad negra. La novela aborda la trágica historia de una antigua esclava, Sethe, cuya decisión de escapar de la plantación no la salvó del trauma de la esclavitud. El objetivo de este ensayo es analizar los temas principales de la novela, como la esclavitud y la maternidad, y correlacionarlos con la problemática racial actual en Estados Unidos. Para ello, haré una breve introducción al movimiento Black Lives Matter (BLM), qué es y sus objetivos en la lucha contra el racismo. Así, se demuestra que Beloved de Morrison no es una mera obra de arte, sino que tiene un profundo componente psicológico que la convierte en una novela de protesta.Grado en Estudios Inglese

Étude de l'ajout d'acétate de sodium dans une culture de clostridium acétobutylicum ATCC 824 face à la production de riboflavine et butanol en bioréacteur cuvée

Les Clostridium acétobutylicum sont des microorganismes connus par la communauté scientifique pour leur capacité de production de solvants lors d’une fermentation appelée ABE (i.e. pour acétone, butanol et éthanol). Néanmoins, bien que l’industrie pétrochimique soit la principale source pour la synthèse de carburants, plusieurs causes environnementales et économiques font que la production de biobutanol, un biocarburant produit par une fermentation menant également aux composés acétone et éthanol (fermentation appelée ABE), connaît un regain d’intérêt depuis quelques années, tant pour des raisons environnementales qu’économiques. Par ailleurs, des travaux réalisés dans le but d’améliorer la gestion du pH du milieu de culture, par ajout d’acétate de sodium, a permis d’observer la coproduction non négligeable de riboflavine en plus du biobutanol et des autres solvants; la riboflavine étant une vitamine (B2) qui n’est normalement synthétisée qu’à l’état de traces dans un milieu de culture standard en fermentation ABE. En effet, la concentration de cette vitamine produite par les Clostridium a pu atteindre 200 mg L-1 suite à un ajout de 60 mM d’acétate de sodium au milieu de culture à l’inoculation. Dans le but de connaître l’effet de l’ajout d’acétate de sodium sur la production de solvants et de riboflavine par les Clostridium acétobutylicum, différentes concentrations initiales de ce composé ont été testées sur des cultures en bioréacteur opérés en mode cuvée. Le suivi de la croissance cellulaire a également révélé que celle-ci dépendait de la quantité d’acétate de sodium ajoutée dans le milieu. Les résultats des suivis de la concentration de solvants formés ainsi que celle de la riboflavine ont également montré que la concentration de l’additif affectait considérablement les concentrations maximales en produits obtenus ainsi que le taux de consommation du substrat carboné, le xylose. Une concentration en acétate de sodium de 100 mM aurait un pouvoir tampon relativement élevé au point de faire prolonger significativement la phase acidogène des cellules, et ainsi nuire à la productivité en solvants et en riboflavine. Le suivi de la concentration des métabolites intracellulaires confirmerait cette hypothèse avec des concentrations en nucléotides particulièrement élevées en début de culture, avec consommation considérable lors de la phase solvantogène, les deux phases successives de la fermentation ABE. Les productions en solvants et en riboflavine se sont révélées sensibles à la concentration de l’ajout. Les cellules cultivées à 60 mM ont atteint les concentrations maximales en solvants et en riboflavine en fin de culture. ---------- Clostridium acétobutylicum are bacterial microorganisms known by the scientific community for their capacity to produce solvents during a fermentation called ABE (i.e. for acetone, butanol and ethanol). However, although the petrochemical industry is the main source of fuel synthesis, several environmental and economic causes have led to a renewed interest in the production of biobutanol by ABE fermentation in recent years. Moreover, work carried out with the aim to study and tampered culture pH variations adding sodium acetate, allowed to observe the co-production of riboflavin in addition to biobutanol and the other solvents; riboflavin being a vitamin (B2) which is normally synthesized only in trace amounts in ABE fermentation. Indeed, the concentration of this vitamin produced by the Clostridium could reach 200 mg L-1 following an addition of 60 mM of sodium acetate to the culture medium at inoculation. With the aim to better characterize the effect of adding sodium acetate on the production of solvents and riboflavin in Clostridium acétobutylicum, different initial concentrations of this added compound were tested on bioreactor cultures operated in batch mode. Cell growth, solvents and riboflavin concentrations as well as the consumption rate of the substrate xylose, the carbon source, all revealed being affected by the amount of sodium acetate added to the medium. Results also showed a concentration of 100 mM sodium acetate having a high buffering capacity the acid-forming phase, thus impairing the productivity of solvents and riboflavin in the following solventogenesis phase. Intracellular metabolites concentration confirmed this hypothesis with particularly high energetic nucleotides concentration at the beginning of the culture, without observing their increased consumption in the solventogenesis phase. The cells cultured at an initial sodium acetate of 60 mM reached the maximum concentrations of solvents and riboflavin at the end of culture
