Stochastic stability of TCP networks under random packet dropping schemes
Creators: name: Maskery, Michael
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: Mathematics.
subject: Engineering, Electronics and Electrical.

description: This paper investigates the stability of TCP networks when packets are randomly dropped at bottleneck routers with a constant or near-constant probability. Analysis of a previously developed system of stochastic differential equations leads to the proposal of a new router algorithm, RWFD, which drops packets with a nearly constant probability. Stability is then investigated for a single TCP connection when this probability is constant. The connection is viewed on a new time scale and modelled as a general state-space Markov chain. Ergodic theory and Foster-Lyapunov drift conditions are employed to show that the Markov chain converges to a steady-state distribution. Stability for near-constant loss probabilities is also considered. The results are extended through the Law of Large Numbers to conclude that constant drop probabilities may cause large TCP networks to converge to a known fixed point. Simulation verifies that RWFD is similarly well behaved, while automatically adapting to network conditions.
Marginal Genre/Marginal Gender: Australian Women Writers and the Short Story
Creators: name: Pes, Annalisa
Publisher: name: Iperstoria
Year: 2020

description: The article examines the narrative techniques and problematic concerns in some representative short stories by XIX and XX century Australian women writers (i.e., Ada Cambridge, Rosa Praed, Barbara Baynton, H.H. Richardson, K.S. Prichard, Marjorie Barnard, and Kate Grenville). The aim of the article is to give evidence of a distinctively female literary tradition of the short story in Australia that has asserted itself in a male-dominated literary context, and that in the meantime has contributed to the development of the genre and to the making of the Australian literary canon. The article begins by drawing a parallel between the non-hegemonic, allegedly ‘minor’ literary status of the short story and the marginal, under-estimated position (at least for a long time) of Australian women writers in a patriarchal society. In this light, the article is meant to prove that women’s short stories can be considered as a form of feminine colonial/postcolonial resistance to imperial/patriarchal dispensations, not only because they mine masculine ascendancy, but also as they rethink gender identity. Australian women’s stories, indeed, often explore new possibilities for ‘femaleness’, that take distance both from the model defined by the metropolitan centre (i.e. deriving from the moral, social and aesthetic values of Victorian England) and from the dominant patriarchal ideology of the Australian colony, and in this way they manage to elude and subvert institutional power.

The Legal Geographies of Water Claims: Seawater Desalination in Mining Regions in Chile
Creators: name: Campero, Cecilia
name: Harris, Leila
Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2019

description: The use of desalination has been increasing in recent years. Although this is not a new technology, its use often proceeds within ill-defined and ambiguous legal, institutional, economic and political frameworks. This article addresses these considerations for the case of Chile, and offers an evaluation of legal ambiguities regarding differences between desalinated water and other freshwater sources and associated consequences. This discussion reviews court records and legal documents of two companies operating desalination plants, both of which have simultaneous rights granted for underground water exploitation: the water supply company in the Antofagasta Region and Candelaria mining company in the Atacama Region. The analysis shows that issues of ambiguity and gaps in the legal system have been exploited in ways that allow these entities to continue the use and consumption of mountain water. They do so by producing desalinated water, and by entering into water transfer and diversion contracts with the mining sector. These findings highlight the importance of undefined socio-legal terrain in terms of shifting hydro-geographies of mining territories, contributing conceptually to critical geographies of desalination, delineating the importance of legal geographies important for water governance, as well as empirically documenting the significance of this case to consider shifts for the mining sector and water technologies and uses in contemporary Chile.

Peso della libertà o repubblica dell'immaginazione? Il caso Nafisi

description: A critical analysis of the dual perspective developed by the Iranian-American scholar and memoirist, Azar Nafisi, from the bestseller Reading Lolita in Tehran: A Memoir in Books (2003) to the most recent The Republic of Imagination: America in Three Books (2014). Actually, Nafisi’s positions epitomize a controversial case study focused on the exile discourse and the inclination towards a kind of transnational identity passing through the so called “imaginative knowledge”. Through the lens of a recurring celebration of Western myths of freedom, a series of stereotypes and paradoxes are investigated in relation to the censorship experienced by the author under the Islamic Republic of Iran, but also to the following attempts, described by the same writer, to acquire the American citizenship. Moreover, Nafisi’s juxtaposition of political and literary topics is shown as an ambivalent narrative strategy, despite the author’s search for a “true self” without any ideological engagement. The explored split between oriented dissertations and pure imaginative recreation enable to reconsider Nafisi’s memoirs as committed depictions of a Westernized legacy.

description: The use of pesticides has served to enhance the economies and health of nations around the world by amplifying crop production and reducing crop loss. At the same time, studies have linked pre- and post-natal pesticide exposures to certain childhood cancers, neurological deficits, and adverse pregnancy outcomes. We explored the relationship between parental pesticide exposure during the pre-conception (3 months prior to conception) and post-conception (first trimester, entire pregnancy period) periods on specific child health outcomes. Our results suggest that pre-conception exposure to cyanazine and dicamba increase the risk of birth defects in male offspring. There is also evidence suggesting that hearing problems and allergies or hayfever are more common in male offspring who are exposed to pesticides during pregnancy. However, given the limited research in this area and the self-reported nature of the exposure and outcomes in this study, the present findings should be considered primarily as hypothesis generating.

description: The multiple-input and multiple-output (MIMO) principle is a well-established method to improve the angular resolution of radars. Due to hardware limitations the maximum number of transmit and receive channels is often limited. In order to further increase the angular resolution with a given number of hardware channels, sparse arrays can be employed. However, the optimal placement of the antenna positions is a critical design parameter and it is difficult to consider non-idealities and mutual coupling within the design process. This paper addresses the non-idealities and the influence of coupling on the virtual array positions of a MIMO radar. An efficient calibration method to determine the real antenna positions is proposed. The discrete Fourier transform (DFT) based direction-of-arrival (DoA) estimation is shown with measurements of a 77 GHz and a 160 GHz MIMO radar for a uniform linear array (ULA) and two sparse arrays in comparison.

description: New tools for non-specific primary prevention strategies covering somatic and mental health in occupational medicine are urgently needed. Heart rate variability (HRV) reflects the capacity of the body to adapt to environmental challenges and of the mind to regulate emotions. Hence, a 24 h-measurement of HRV offers a unique possibility to quantify the interaction between situation-specific emotional regulation within a specific psychosocial environment and physiological state, thereby increasing self-perception and inducing motivation to change behavior. The focus of the present study represents such a 24 h-measurement of HRV and its presentation as a comprehensive graph including protocol situations of the client. A special training program for occupational health physicians and questionnaires for clients were developed and administered. The article reports the first data of the study “healthy leadership and work – body signals for managers and employees”, an investigator-initiated, interventional, single-arm, open (non-blinded), multicenter, national trial with 168 participants. They reported a significantly improved perception of their bodily needs after the consultation (from Median = 7, interquartile range 5–8 to Median = 8, interquartile range 7–9; scale range from 1 to 10; p < 0.001, Wilcoxon rank test; effect size 0.49). The 16 occupational health physicians stated that the measurement of HRV was very well suited to enter into dialog with the managers and was feasible to show interactions between situations, thoughts, feelings, and bodily reactions. Taken together, we show that a 24 h-HRV-measurement can be a feasible and effective approach for holistic, psychosomatic primary prevention in occupational medicine. We discuss possible mechanisms for improving the individual health via the consultation, containing mindset and improved ANS activity.

description: In the present study, event-related potentials (ERPs) were registered during a semantic negative priming (NP) task in participants with higher and lower working memory capacity (WMC). On each trial participants had to actively ignore a briefly presented single prime word, which was followed either immediately or after a delay by a mask. Thereafter, either a semantically related or an unrelated target word was presented, to which participants made a semantic categorization judgment. The ignored prime produced a behavioral semantic NP in delayed (but not in immediate) masking trials, and only for participants with a higher-WMC. Both masking type and WMC also modulated ERP priming effects. When the ignored prime was immediately followed by a mask (which impeded its conscious identification) a reliable N400 modulation was found irrespective of participants’ WMC. However, when the mask onset following the prime was delayed (thus allowing its conscious identification), an attenuation of a late positive ERP (LPC) was observed in related compared to unrelated trials, but only in the higher-WMC group showing reliable behavioral NP. The present findings demonstrate for the first time that individual differences in WMC modulate both behavioral measures and electrophysiological correlates of semantic NP.
Automation of continuous composite two-dimensional braiding process

Subjects: subject: Engineering, Mechanical.

description: This work presents the design of a computer controlled pilot production plant capable of manufacturing hybrid braided/pultruded rod on a continuous basis. The current product design utilizes a high modulus carbon fiber core with a braided over-wrap composed of various materials. Production is accomplished in three phases: core fiber sorting and impregnation, 2D braiding, and resin curing. On-line impregnation of the core strands is accomplished using a pressure-fed impregnation ring. Deposition of the 2D braid is performed by a Maypole braider. Curing of the resin is accomplished using a novel two phase method. An induction heater first increases the temperature of steel wires embedded in the rod core. Next three tunnel ovens provide heat flux to the exterior of the rod. A caterpillar-type puller is used to advance the rod through the process. Prior to this work production was accomplished by manually adjusting machinery operating parameters through controls distributed throughout the production facility. This led to inconsistent quality product. The modifications to production equipment and the development of an automation system which allow one to improve. The modifications to production equipment and the development of an automation system which allow to improve product quality are the main topics of this work. The automation system is based on a PC equipped with several data acquisition cards. A global controller calculates machine set points based on product specifications and measured production rate. Cascade controllers are tasked to regulate machine operations about these set points. The rotational speed of the braider head and puller are monitored using incremental encoders and are under set point element and integral control. The resin flow rate is estimated from weight measurement of the resin reservoir. To regulate the resin dispensing process a calibration curve is used as a set point elements while disturbances are rejected using integral control. The curing oven temperatures are monitored using thermocouples. The oven temperatures are regulated using gain scheduled PI controllers. The modification to the production equipment and the development of the automation system allowed for significant improvements in the product quality.

description: Streptococcus anginosus ß‐hemolytic strains harbor CRISPR/Cas systems less frequently than non ß‐hemolytic strains. While in 65% of non‐ß‐hemolytic strains a type II CRSIPR/Cas system was present, it could only be detected in 24% of ß‐hemolytic strains. Streptococcus anginosus is a commensal of the oral mucosa that can cause severe invasive infections. A considerable proportion of Streptococcus anginosus strains are ß‐hemolytic due to the presence of an SLS‐like gene cluster. However, the majority of strains do not display ß‐hemolysis. To investigate ß‐hemolysin heterogeneity in S. anginosus, we determined the presence of sag genes and correlated it with the presence of CRISPR/Cas genes in a collection of ß‐hemolytic and non‐ß‐hemolytic strains. All of the ß‐hemolytic strains carried the sag gene cluster. In contrast to other streptococci, clinical S. anginosus strains that do not display ß‐hemolysis do not harbor sag genes. Phylogenetic analysis of the ß‐hemolytic strains revealed that they belong to two previously defined clusters within S. anginosus. Correlation with CRISPR/Cas genes showed a significant difference for the presence of CRISPR/Cas in ß‐hemolytic versus non‐ß‐hemolytic isolates. The presence of the CRISPR/Cas type IIA or type IIC locus is associated with the absence of sag genes; in 65% of the non‐ß‐hemolytic strains a CRISPR/Cas locus was found, while only 24% of ß‐hemolytic strains carry CRISPR/Cas genes. Further analysis of the spacer content of the CRISPR systems revealed the presence of multiple self‐targeting sequences directed against S. anginosus genes. These results support the hypothesis that horizontal gene transfer is involved in the acquisition of ß‐hemolysin genes and that CRISPR/Cas may limit DNA uptake in S. anginosus.

A relationship between adolescent identity resolution and vocational maturity.
Creators: name: Hawes, Frank.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1978
Subjects: subject: Education, Secondary.

description: In this study the research problem focused on adolescent vocational maturity and its antecedent dynamics. It was argued that vocational maturity, a construct used to assess degree of readiness for career bahavior, lacked a conceptual framework to compare individual dynamics. It was proposed that Erikson's theory of psychosocial identity development would serve to explain certain antecedent conditicns which facilitate or impede vocational maturity. The research hypothesis, that vocational maturity is a function of degree of identity resolution, was put forth. To study this problem, ninety-six senior high school boys from two Ottawa schools were interviewed and classified into identity status as a measure of identity resolution, and administered the Career Development Inventory as a measure of vocational maturity. Vocational maturity scores were compared across the four identity status groups using a univariate analysis of variance technique. The research hypothesis was supported. Post hoc procedures and multivariate analysis of the three subscales of the Career Development Inventory were applied. These results also supported the theoretical rationale. Vocational maturity mean scores were significantly different between the majority of pairs of identity status groups; only two non-predicted discrepancies were found. Subsequently, the subscales accounting for the discrepancies were identified. Recommendations were made regarding high school career guidance appropriate to differing degrees of identity resolution.

description: We present Keck spectroscopic observations of three probable high-redshift superluminous supernovae (SLSNe) from the Subaru HIgh-Z sUpernova CAmpaign (SHIZUCA), confirming redshifts of 1.851, 1.965, and 2.399. The host galaxies were selected for transient monitoring from multiband photometric redshifts. The supernovae are detected during their rise, and the classically scheduled spectra are collected near maximum light. The rest-frame far-ultraviolet (similar to 1000-2500 angstrom) spectra include a significant host galaxy flux contribution, and we compare our host-galaxy-subtracted spectra to UV-luminous SNe from the literature. While the signal-to-noise ratios of the spectra presented here are sufficient for redshift confirmation, supernova spectroscopic type confirmation remains inconclusive. The success of the first SHIZUCA Keck spectroscopic follow-up program demonstrates that campaigns such as SHIZUCA are capable of identifying high-redshift SLSNe with sufficient accuracy, speed, and depth for rapid, well-cadenced, and informative follow-up.
Sex, motivation, extraversion and neuroticism as multiple predictors and moderators with predicting two grade nine attainment criteria.
Creators: name: Perrault, Yvonne L.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1976
Subjects: subject: Education, Educational Psychology.

description: Although the moderator variable concept has acquired popularity among researchers concerned for the low predictive validity of psychological tests, no conclusive evidence has been presented for the greater effectiveness of moderated prediction techniques over the traditional multiple regression model. It was the principal aim of this research to investigate whether use of sex and five measures of personality and motivation as moderators would increase the size of correlations of a mental ability predictor with criteria of academic success. As behaviour may be sensitive to the conditions in which it occurs, the research also sought to determine whether use of school grades and standardized achievement tests as criteria might obtain inconsistent results. The Ss in this investigation were 246 males and females enrolled in grade nine at a public high school. They were, initially administered a battery of tests designed to measure mental ability, extraversion, neuroticism, and three aspects of academic motivation. Six weeks later, standardized reading and mathematics achievement tests were administered to the same Ss. End-of-year grades in english and mathematics also were obtained. The sets of achievement test scores and grades were combined to yield two overall criterion measures. A statistically significant improvement was demonstrated (P < .05, one-tailed) in support of using the extraversion variable as a moderator when predicting achievement test performance. The more accurate prediction was given for a subgroup with scores in the low one-third of the extraversion distribution. Joint use of the sex, personality and motivation variables did not enhance this moderator effect. In no case did the moderator analysis provide a significant improvement over the traditional multiple regression technique when predicting school grades. These research findings were interpreted and discussed in terms of their implications for psychological theory and research.
Capital, labour and lumber in A. R. M. Lower's woodyard: James MacLaren and the changing forest economy, 1850-1906.
Creators: name: Hammond, Lorne F.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: History, Canadian.

description: In reaction to A.R.M. Lower's forest studies, which emphasize the role of markets and tariffs, it is argued that both capital and labour demonstrate extensive agency during the transition between Canada's exports of lumber to Britain and the United States. A series of micro-studies explore the socio-economic transition from colonial to corporate forestry, within a regional framework integrating rural and urban experiences. The succession between economies is examined, from fur to lumber, land speculation, to merchant capital and pioneer sawmilling, to the Ottawa Valley capitalist. The example, James MacLaren, used kinship capital pools and strategic business alliances to rise to the position of independent capitalist lumberman and Bank president. The labour institutions upon which his business was based, the shanty and the timber cove, were anchored to a web of household economies, both urban and rural. Families drew on monthly shanty wages. The shanty was common ground for small kin-groups of local farm workers, urban sawmiil workers, migrant workers, and a core of professional lumberers, resident in Ottawa. Staggered waves of arrival and departure show flexibility in when one decided to leave the farm for the shanty, implying it was a complementary institution. MacLaren's cove in Quebec City also accommodated rural workers amid numerous small non-union strikes. Across the harbour, timber ship labourers, divided over ethnicity and technology, coalesced violently into one of the country's strongest unions. As industrial lumber barges replaced rafts, sawmills replaced coves as export points. MacLaren used both to sell to British and U.S. markets simultaneously, expanding his investments into Vermont and New York. His capital was redeployed in resource developments, such as mining and railways, or local real estate, in a regional pattern that cut across the "Empire of the St. Lawrence". His connections were with American investors or competitors--Cleveland steel elites or the House of Morgan. The Bank of Ottawa, built upon his gathering of local groupings of capital, eventually found regional identity a hinderance in raising capital. Unable to make inroads into other markets, it merged with the Bank of Nova Scotia. In 1904 a successful appeal was made to the State to close timber limits against settlement. This was to make forests more acceptable as collateral to make the transition to pulp and paper. Couched in the discourse of fire, the closing of the forest common marks the true end of the frontier. For Quebec, this is the final abandonment of agrarian colonisation for a development model based on state supported large scale corporate forestry, mining and hydro-electric development.
Language and Identity of the British Indian Teenage Diaspora: Gautam Malkani's Londostani, a Case Study
Creators: name: Renna, Dora
Publisher: name: Iperstoria
Year: 2020

description: The work aims to shed some light on the role of language during a crucial step of life when it comes to identity, that is to say youth – the age of uncertainty par excellence, in which every convention, every belief is put into question and re-elaborated. Moreover, the analysis will focus on the teenagers of the British Indian diasporic community, for whom the research of an identity also includes the definition of belonging. In this reconnaissance phase, the issue will be tackled by reading Gautam Malkani’s debut novel, Londonstani (2006). The amazing ability of Malkani is to disclose how the issue of identity is played into language – each attempt to find a definition, to establish or break bonds of belonging, to disobey institutions and to adapt to the rules of a subgroup. Language becomes more than just a tool to communicate: the means becomes the message, transcending its content. The most striking aspect of the language of the Londonstani teens is that they do not speak “pure” English nor Punjabi, but a language made of encounters, clashes, and hybridization. Malkani catapults the reader into a completely unknown linguistic and cultural reality, not making any effort to make the reader feel “comfortable.” Words and sentences from different languages and traditions, references coming from Indian and African American culture are constant and rarely explained. Malkani is there to overturn expectations and to show how many languages become one in a land, in a city (London) that is the symbol of diaspora, a great third space of negotiation and fragmentation, where identities are lost to be found again – new, multifaceted, unstable.

Due to the fact that the majority of the population within Quebec is Francophone, several researchers of Paganism have cast doubts as to whether the Pagan movement could ever take root in the province. This research is an ethnographic study of Paganism in Montreal, Quebec's largest city and sole metropolis, using participant-observation, survey questionnaires, and one-on-one interviews in both English and French. This research aims to determine whether there are any significant differences between Anglophone and Francophone Pagans in Montreal, the degree to which Quebec culture has influenced the development of the religion within the province, and how the unique and distinct forms of Paganism in Quebec challenge the hegemony of the American model of Paganism. This research also explores the ways the development of a Pagan identity can be likened to the process of ethnogenesis.

description: This work reports the facile synthesis of a Sn–P composite combined with nitrogen doped hard carbon (NHC) obtained by ball‐milling and its use as electrode material for sodium ion batteries (SIBs). The “Sn4P3”/NHC electrode (with nominal composition “Sn4P3”:NHC = 75:25 wt%) when coupled with a diglyme‐based electrolyte rather than the most commonly employed carbonate‐based systems, exhibits a reversible capacity of 550 mAh gelectrode−1 at 50 mA g−1 and 440 mAh gelectrode−1 over 500 cycles (83% capacity retention). Morphology and solid electrolyte interphase formation of cycled “Sn4P3”/NHC electrodes is studied via electron microscopy and X‐ray photoelectron spectroscopy. The expansion of the electrode upon sodiation (300 mAh gelectrode−1) is only about 12–14% as determined by in situ electrochemical dilatometry, giving a reasonable explanation for the excellent cycle life despite the conversion‐type storage mechanism. In situ X‐ray diffraction shows that the discharge product is Na15Sn4. The formation of mostly amorphous Na3P is derived from the overall (electro)chemical reactions. Upon charge the formation of Sn is observed while amorphous P is derived, which are reversibly alloying with Na in the subsequent cycles. However, the formation of Sn4P3 can be certainly excluded.
description: Tin phosphide composited with nitrogen‐doped hard carbon is studied as the negative electrode for sodium ion batteries. The in situ X‐ray diffraction measurements reveal the differences in the storage behavior of tin phosphide in ether and carbonate electrolytes. The in situ electrochemical dilatometry study shows the active role of carbon to diminish the large volume expansion of tin phosphide during the (de)sodiation process.

description: The structural properties and diffusion coefficients of the H2O+NaCl+CO2 ternary system at various NaCl concentrations, temperatures and pressures are investigated using molecular simulation. A CO2 potential model is selected for the simulation of CO2 diffusion coefficient in aqueous solution. As the most appropriate model, it produces simulation results which are in closest agreement with experimental data. The properties of the H2O+NaCl system are examined prior to the H2O+NaCl+CO2 system, including the radial distribution functions, coordination numbers and diffusion coefficients at various temperatures and pressures. Three aspects of the ternary system are studied. First, the diffusion coefficients of the ternary system at different NaCl concentrations are observed. The NaCl concentration is found to have a large impact on both the diffusion coefficients of the ternary system and also the cluster pattern of ions. Second, the diffusion coefficients of the system at different temperatures are studied. Raising the temperature increases the diffusion coefficients and facilitates formation of ions pairs. Finally, the diffusion coefficients of the ternary system at different pressures are investigated. Pressure also has impact, but to a much lesser degree. At 278 K, the higher the pressure, the greater value of the diffusion coefficient. In contrast at a temperature of 298 K, a pressure increase leads to lower diffusion coefficient. Hydrogen bonds at low temperatures may be the reason for the unusual phenomenon. The diffusion data are compared to predictions of two models proposed by Ratcliff and Holdcroft (1963). The first approach is based on activation theory and results in both a linear and exponential relationship. They preferred a linear model over an exponential model due to the limiting experimental data. However, we demonstrate that the exponential model is more suitable for predicting diffusion coefficient with the help of simulation data. The other approach is based on the relation between diffusion coefficient and viscosity, whereby the diffusion coefficient of the gas in electrolyte solution is derived from a given viscosity. The diffusion coefficients obtained from molecular simulation agree with the results from the two equations, demonstrating the accuracy of the two prediction equations.

description: In search for a more sustainable source of fuel, bioethanol has been considered as a primary candidate to achieve this objective. To overcome the competition between food and fuel that is currently developing, bioethanol from lignocellulosic source especially from agricultural residues instead than from corn or sugar cane should be favoured. To hydrolyze the cellulose into fermentable sugars so that they can be used to produce ethanol, cellulase enzyme must be produced efficiently and economically. The objective of the present research is to contribute toward this goal and, in particular, to study the effect of agitation on cellulase production and on the morphology of Trichoderma reesei, the microorganism used to produce this enzyme. A series of eight experiments were conducted in a stirred tank bioreactor (STB) and in a reciprocating plate bioreactor (RPB) at various agitation speeds ranging from 200 to 500 RPM and 0.25 to 1.0 Hz, respectively. For each experiment, image analysis was used to determine changes in morphology of Trichoderma reesei throughout the fermentation. The protein productivity was correlated to one morphological parameter, the hyphal growth unit. It was found that in the STB, low agitation (200 and 300 RPM) resulted in lower protein productivity whereas high agitation (500 RPM) was detrimental to the microorganisms. The optimal speed of agitation was determined to be 400 RPM where the highest productivity was achieved. In the RPB, higher agitation speed resulted in a higher productivity and the highest productivity was achieved at 1.0 Hz. As a second objective, a quick and economical off line method using conventional home blood glucose monitors was developed to measure the glucose concentration during the fungal fermentation of T. reesei. Two monitors, OneTouch Ultra and Ascensia Contour, were tested and implemented for the monitoring of the glucose concentration during both flask and bioreactor fermentations of T. reesei. OneTouch monitor was found to be more suitable.

description: By inducing a Raman transition using a pair of Gaussian and Laguerre-Gaussian laser beams, we realize a Rb87 condensate whose orbital angular momentum (OAM) and its internal spin states are coupled. By varying the detuning and the coupling strength of the Raman transition, we experimentally map out the ground-state phase diagram of the system for the first time. The transitions between different phases feature a discontinuous jump of the OAM and the spin polarization, and hence are of first order. We demonstrate the hysteresis loop associated with such first-order phase transitions. The role of interatomic interaction is also elucidated. Our work paves the way to explore exotic quantum phases in the spin-orbital-angular-momentum coupled quantum gases.
Maritime Reservations: Harboring Indigenous America in Gerald Vizenor's The Heirs of Columbus
Creators: name: Bosco, Stefano

description: The theme of the harbor would appear to be quite peripheral in Native American literature, given the predominance of other, more ‘continental’ places and landscapes in American Indian writing and the cultural significance of the harbor as a primary site of Euro-American immigration, with its flow of people and goods coming mainly from outside the US. However, one of the most provocative and inventive novels appearing in Native American literature over the last few decades, Gerald Vizenor’s The Heirs of Columbus (1991), extensively features such kind of space in its re-imagining of Christopher Columbus’s discovery of America: no longer an act of conquest initiating the genocide of indigenous people in the New World, Columbus’s achievement is first and foremost a return to the land of his imagined Mayan ancestors, spurred by the awakening of “stories carried in the blood”. The novel stands out not only as a postmodernist revision (in Vizenor’s playful and imaginative style) of the Columbian master narrative, but also as an affirmation of indigenous survival and resistance in the face of 500 years of violent Euro-American colonization. Concerned about the repatriation of Columbus’s as well as Pocahontas’s remains back to America, the ‘heirs’ of the title perform a series of actions, among which is the creation of a sovereign ‘maritime reservation’ made up of three floating structures anchored at Lake of the Woods (a casino, a restaurant, and a tax-free market), bearing the names of Columbus’s famous caravels. Thus, Vizenor imagines a bizarre and all-Indian version of the harbor that combines the movable space of Columbus’s enterprise (and, more broadly, of Euro-American colonization) with a Native American sense of territoriality sustaining the resilience and the sovereignty of tribal cultures.
