A novel screening protocol for the differentiation of type of hearing loss in neonatal intensive care unit (NICU) infants
Creators: name: Millman, Tara Pamela
Publisher: name: University of British Columbia
Year: 2011

description: Objective: The current screening protocol of the British Columbia Early Hearing Program for neonatal intensive care unit infants is unable to differentiate between conductive and sensorineural hearing losses at the time of detection. A critical need exists for developing standardized screening procedures for differentiating conductive, sensory, and neural loss in early infancy to provide an appropriate course of intervention and to avoid later consequences on health and the development of speech and language. Design: The current study examined a novel protocol for the hearing screening of neonatal intensive care unit (NICU) infants that involved the measures of 1000 Hz tympanometry, transient evoked otoacoustic emissions (TEOAE), and ipsilateral broadband middle-ear muscle reflex (MEMR) at a 1 kHz probe tone frequency. The GN Otometrics Accuscreen device was used for automated auditory brainstem response (AABR) and TEOAE screening and the GN Otometrics Otoflex diagnostic immittance meter recorded 1000 Hz tympanometry and the MEMR. A total of 90 infants (180 ears) from the NICU of the Royal University Hospital in Saskatoon, Saskatchewan was recruited, of which 78 infants (143 ears) met the inclusion criteria. The participants mean chronological age was 31.38 days. The novel protocol was examined for three components: 1) if it generated equivalent results with the current two-stage AABR hearing screening protocol for NICU infants; 2) for testing length; and 3) for challenges encountered during testing. Results: Results revealed that 70.6% of infants passed both the current AABR and novel protocols. TEOAE accounted for most of the referrals for infants who passed the current AABR screening protocol and referred on the novel protocol (70%) and for infants who referred on both protocols (83.3%). Conclusion: The novel protocol might provide more information regarding the reason for a screening referral, including the identification of middle-ear dysfunction and the detection of mild hearing impairment.

description: We present a theory of modified gravity, inspired by the gauge theories, where the commutator algebra of covariant derivative gives us an added term with respect to the General Relativity, which represents the interaction of gravity with a substratum. New spherically symmetric solutions of this theory are obtained and can be view as solutions that reproduce, the mass, the charge, the cosmological constant and the Rindler acceleration, without coupling with the matter content, i.e., in the vacuum.

description: Chile became the first country to protect brain data as a constitutional right in 2021. This thesis investigates the spatial and temporal position of the respective “NeuroRights” amendment by conducting a theological genealogy of number 1° of article 19 of the 1980 Constitution, including ratified amendments thereafter, until 2021, through engaging governing documents, such as the 1925 Constitution, the 1833 Constitution, and the unsuccessful Chilean constitution of 2022. Through understanding the positionality of the NeuroRights, as well as those forces that have brought such legislation into existence, the ethnographer becomes equipped to build themselves, as well as the world around them.

description: La Organización Mundial de la Salud (OMS) define la violencia como el empleo de la fuerza por parte de una persona con el propósito de causar daño a otra, abarcando manifestaciones físicas, emocionales, sexuales y verbales. A nivel global, la violencia se reconoce como un problema social significativo, evidenciado por el hecho de que una de cada tres mujeres, en edades comprendidas entre los 15 y 49 años, ha experimentado violencia en algún momento de su vida. Objetivo: Este estudio se propone determinar la relación entre violencia de género y la autoestima en los estudiantes de 8vo semestre de la carrera de Psicología. Metodología: Para llevar a cabo la investigación, se empleó una metodología cuantitativa, descriptiva y correlacional, con un enfoque transversal. La recopilación de datos se realizó mediante encuestas, utilizando la Escala de Riesgo de Violencia contra la Pareja para Ecuador y la Escala de Rosenberg, una para cada variable. La muestra, constituida por 92 estudiantes de octavo semestre de Psicología, se seleccionó mediante muestreo no probabilístico por conveniencia. Resultados: Los resultados revelan que el 83,77% de los encuestados presenta un bajo nivel de violencia, mientras que el 12% muestra un nivel moderado y un 4,3% exhibe un nivel alto. Respecto a la autoestima, el 97,8% de los participantes tiene un nivel bajo, el 2,2% evidencia un nivel medio, y no se registran niveles altos de autoestima entre los participantes. Conclusiones: se establece que el índice de violencia entre las estudiantes de octavo semestre es bajo, y aunque el nivel de autoestima es predominantemente bajo, no se encuentra una relación directa entre estas dos variables estudiadas. Aunque la literatura sugiere una conexión entre la autoestima y ser víctima de violencia, en este grupo específico, donde los niveles de violencia son bajos y la autoestima también lo es, se sugiere que existen otros factores que inciden en la autoestima de las estudiantes.

description: A solid-phase extraction (SPE) method was established for fipronil and its metabolite residues (fipronil desulfinyl, fipronil sulphone and fipronil sulphide) in eggs with a covalent triazine framework (CTF) porous material as the adsorbent followed by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) detection. Multiple probes and quantum chemistry theory calculations were conducted to describe the versatile adsorption property directly and quantifiably. The conjugated structure of CTF and N-containing triazine generated π-π interactions and hydrogen bonds between the CTF and the targets, which led to high extraction efficiency and recoveries. The solid-phase extraction parameters, including amount of the adsorbent, type of eluent, amount of eluent and loading rate were investigated. Under the optimal experimental conditions, the recoveries of the analytes were between 85.5% and 103.2%, and the RSD (n = 5) was between 1.8% and 3.6%. The LODs and LOQs were 0.13–0.2 ng g−1 and 0.5–0.8 ng g−1, respectively. The sorbent can effectively reduce the interference of the matrix and meet the detection requirements of fipronil and its metabolites in eggs. These results imply that the CTF as adsorbents have great potential in the analysis of trace targets in samples with complex matrices.

description: Cultural heritage is not only important from an economic perspective by bringing business opportunities to communities, but also due to its role in shaping our cultural identity. At the same time, cultural heritage is endangered by natural hazards, the effects of which are exacerbated by climate change, threatening the integrity and potentially compromising the value of heritage sites. The goal of the Horizon 2020-funded project STORM (Safeguarding Cultural Heritage through Technical and Organisational Resources Management) is to provide critical decision-making tools to European cultural heritage stakeholders affected by climate change, and to improve cultural heritage sites’ climate change resilience through the development of services ranging from comprehensive heritage site monitoring to incorporating information regarding future climate in the disaster risk reduction process.

Here, the STORM project is presented, with a focus on the use of climate change information in the risk assessment and risk management process for cultural heritage. After briefly outlining the STORM-developed risk assessment methodology, the use of climate change information in this process, derived using observations, statistical downscaling and EURO CORDEX data, is discussed in detail based on the example of one of the STORM pilot cultural heritage sites. Combining the climate analysis results with cultural heritage site specific information, risk maps are produced that form the basis for further actions to reduce these risks. In this way, regional scale climate information is translated to a user-friendly format, directly feeding heritage sites’ risk management decision-making process, allowing for the STORM-methodology to be viewed as a climate service.

description: This study presents multi-wavelength observational results for energetic GRB100414A with GeV photons. The prompt spectral fitting using Suzaku/WAM data yielded spectral peak energies of E^src_peak of 1458.7 (+132.6, -106.6) keV and Eiso of 34.5(+2.0, -1.8) x 10^52 erg with z=1.368. The optical afterglow light curves between 3 and 7 days were effectively fitted according to a simple power law with a temporal index of alpha=-2.6 +/- 0.1. The joint light curve with earlier Swift/UVOT observations yields a temporal break at 2.3 +/- 0.2 days. This was the first \fermi/LAT detected event that demonstrated the clear temporal break in the optical afterglow. The jet opening angle derived from this temporal break was 5.8 degree, consistent with those of other well-observed long gamma-ray bursts (GRBs). The multi-wavelength analyses in this study showed that GRB100414A follows E^src_peak-Eiso and E^src_peak-E_gamma correlations. The late afterglow revealed a flatter evolution with significant excesses at 27.2 days. The most straightforward explanation for the excess is that GRB100414A was accompanied by a contemporaneous supernova. The model light curve based on other GRB-SN events is marginally consistent with that of the observed lightcurve.

description: Public health will face major challenges in the coming decades. The 1999 West Nile outbreak in New York City and other recent incidents demonstrate how important public health is as a frontline defense against emerging infections, bioterrorism, and other unexpected emergencies. A well-prepared public health workforce is more critical than ever. The challenges are particularly great in urban areas, which traditionally serve as ports of entry, may be appealing targets to terrorists, and have large and diverse populations with complex health risk factors. To better prepare the public health workforce to carry out routine functions effectively and fulfill the additional roles required in emergencies, a national network of "Centers for Public Health Preparedness" has been established by the Centers for Disease Control and Prevention (CDC). The network currently includes seven academic Centers funded through a cooperative agreement with the Association of Schools of Public Health (ASPH). Goals include the development of competency-based public health practice courses primarily designed to utilize distance-learning technology (such as World Wide Web-based instruction) that can be implemented locally and replicated nationally. The Center for Public Health Preparedness at the Mailman School of Public Health, Columbia University, is working toward these goals in partnership with the New York City Department of Health (NYC DOH).

description: Following the FDA's approval of a pediatric dosage Atropen®, the Pediatric Expert Advisory Panel was asked to review the existing guidelines and recommendations regarding the treatment of children exposed to nerve agents and the Mark-1 Kit; review the new literature on pediatric nerve agent exposure; and to develop recommendations and guidelines for this new device including modifications to the existing recommendations and guidelines if warranted. In May 2003, the first nationally accepted pediatric disaster and terrorism preparedness recommendations and treatment guidelines were issued by the Program for Pediatric Preparedness of the National Center for Disaster Preparedness (NCDP). These guidelines were based on a National Consensus Conference sponsored by the Program for Pediatric Preparedness and funded by the Agency for Healthcare Research and Quality and the EMS for Children Program of the Health Resources and Services Administration. At that time, the only available treatment for certain types of nerve gas exposure (predominantly those with anticholinesterase properties) was the Mark 1 kit. The recommendations were based on established usage of antidotes for cholinergic toxicity and were felt to be both safe and supported by the literature. It was stated that the Mark 1 Autoinjector kits (although not approved for pediatric use) should be used as initial treatment for children with severe, life-threatening nerve agent toxicity for whom IV treatment is not possible or available, or for whom more precise IM (mg/kg) dosing would be logistically impossible. It was further felt that while not within the published dosage range for cholinergic toxicity, if a Mark 1 kit was the only source of atropine and pralidoxime available after a bona fide exposure it should be used to treat all children, even those younger than 3 years old. Furthermore, it was felt to be imperative to expedite approval of the pediatric autoinjector kit (which contains both atropine and an oxime and is designed for children) that is currently produced and marketed abroad but not available in the United States.

description: We use computational and experimental methods to study d0 ferromagnetism at a charge- imbalanced interface between two perovskites. In SrTiO3/KTaO3 superlattice calculations, the charge imbalance introduces holes in the SrTiO3 layer, inducing a d0 ferromagnetic half-metallic 2D electron gas at the interface oxygen 2p orbitals. The charge imbalance overrides doping by vacancies at realistic concentrations. Varying the constituent materials shows ferromagnetism to be a gen- eral property of hole-type d0 perovskite interfaces. Atomically sharp epitaxial d0 SrTiO3/KTaO3, SrTiO3 /KNbO3 and SrTiO3 /NaNbO3 interfaces are found to exhibit ferromagnetic hysteresis at room temperature. We suggest the behavior is due to high density of states and exchange coupling at the oxygen t1g band in comparison with the more studied d band t2g symmetry electron gas.

description: In March 2008, the Alberta Gaming and Liquor Commission (AGLC) and Alberta Health Services–Addiction and Mental Health(AHS–AMH)* took action to jointly develop a renewed Problem and Responsible Gambling Strategy for 2010–2014, to address problem gambling and promote responsible gambling in a collaborative, comprehensive and sustainable manner. Gambling is a popular recreational activity enjoyed by thousands of Albertans. Revenues from the province’s charitable gaming model support health, research, education, recreation and cultural programs. The gambling industry provides jobs and contributes to Alberta’s tourism and hospitality sectors. 82% of Albertans have gambled in one form or another. Of those, 1.3% are at high risk of becoming problem gamblers. 3.9% are at moderate risk, and 9.8% are at low risk of developing gambling problems. The minority of gamblers who develop gambling problems can face social, financial, legal and health-related problems which can impact their families, workplaces and communities. Implementing the strategies outlined in this framework will help to ensure that the social, charitable and economic benefits of gambling continue to far outweigh any negative societal costs, and to ensure the long-term sustainability of a vibrant gaming industry in Alberta.

description: Selenium (Se) is an essential micronutrient for humans. Garlic (Allium sativum L.) metabolises Se into important Se-amino acids like Se-methylselenocysteine (Se-MetSeCys), precursor of methylselenol, an active species for cancer prevention. Therefore, the Se accumulation and speciation in garlic were studied to evaluate their relations with growth stages and types of plant clones. Four garlic clones (Nieve INTA, Union FCA, Gostoso INTA and Rubí INTA) were fortified with a Se solution (169 g Se L−1). The association of Se to different molecular weight fractions was evaluated by size-exclusion chromatography coupled to inductively coupled plasma mass spectrometry (SEC-ICP-MS) detection. Also, anion exchange chromatography (AEC-ICP-MS) was used for the determination of Se-amino acids, while their identification was performed by ESI-MS/MS. The Se was incorporated into high (7–5 kDa) and low (2–4 kDa) molecular weight fractions. The presence of Se-MetSeCys was observed mostly. Se-MetSeCys increased in bulbs to a maximum value but increased, then decreased, in leaves and roots. The Se-organic species were mostly found in bulbs in the last growth stage. Garlic showed a significant ability to accumulate and metabolise Se, specially, the red clones (Gostoso INTA and Rubí INTA). Also, this work suggests that this plant may become an attractive source of Se-amino acids with important biological properties.

description: As Redes de Dados Nomeados (NDN) apresentam um novo modelo de comunicação em que os dados nomeados na camada de rede potencializam operações não possíveis na rede IP. Com essa nova abordagem, a NDN oferece uma comunicação mais adequada ao padrão atual de consumo de conteúdo da Internet. Os usuários e aplicações atuais buscam recuperar o conteúdo sem se preocupar onde estão armazenados. Embora a NDN atenda ao requisito imposto, os dados trafegados são tratados sem distinção, independentemente do tipo de aplicação que os geraram, com base no melhor esforço e sem garantias. Em um cenário realista, a rede tende a operar com um tráfego elevado de pacotes oriundos de diferentes aplicações e dispositivos. Dessa forma, a rede precisa estar ciente da diferenciação de serviços para oferecer um tratamento adequado aos fluxos de dados de acordo com seus requisitos. Neste contexto, este trabalho investiga uma arquitetura NDN ciente da diferenciação de serviços para oferecer uma melhor qualidade de serviço aos usuários e melhor gerenciamento do tráfego da rede. A solução proposta busca maximizar os benefícios já oferecidos pela NDN e explorar questões arquiteturais que têm potencial de alavancar a implantação da NDN ciente de diferenciação de serviços.

description: We investigate the effects of nonmagnetic disorder on the Ruderman-Kittel-Kasuya-Yoshida (RKKY) interaction in graphene by studying numerically the Anderson model with on-site and hopping disorder on a honeycomb lattice at half filling. We evaluate the strength of the interaction as a function of the distance R between two magnetic ions, as well as their lattice positions and orientations. In the clean limit, we find that the strength of the interaction decays as 1/R^3, with its sign and oscillation amplitude showing strong anisotropy. With increasing on-site disorder, the mean amplitude decreases exponentially at distances exceeding the elastic mean free path. At smaller distances, however, the oscillation amplitude increases strongly and its sign changes on the same sublattice for all directions but the armchair direction. For random hopping disorder, no sign change is observed. No significant changes to the geometrical average values of the RKKY interaction are found at small distances, while exponential suppression is observed at distances exceeding the localization length.

We reveal multiple nodeless superconducting (SC) gaps with 2D/kBTc ratios varying from 2.8 to 6.4, depending on the Fermi surface (FS). We also succeeded in directly observing a gap anisotropy along the FS with magnitude up to ~30 %. The anisotropy is four-fold symmetric with an antiphase between the hole and electron FSs, suggesting complex anisotropic interactions for the SC pairing. The observed momentum dependence of the SC gap offers an excellent opportunity to investigate the underlying pairing mechanism.

description: Food contact materials (FCMs) can contain hazardous chemicals that may have the potential to migrate into food and pose a health hazard for humans. Previous studies have mainly focused on plastic materials, while data on packaging materials made from paper and cardboard are limited. We used a panel of cell-based bioassays to investigate the presence and impact of bioactive chemicals on human relevant endpoints like oxidative stress, genotoxicity, inflammation, xenobiotic metabolism and endocrine system effects in extracts made from paper and cardboard. In total, 23 methanol extracts of commonly used paper and cardboard available on the Swedish market were extracted as a whole product using methanol to retrieve polar substances, and tested at concentrations 0.3–10 mg/mL and 0.2–6 mg/mL. At the highest concentration bioactivities were observed in a high proportion of the samples: oxidative stress (52%), genotoxicity (100%), xenobiotic metabolism (74%), antiandrogenic- (52%) and antioestrogenic receptor (39%). Packages of potential concern included cake/pastry boxes/mats, boxes for infant formula/skimmed milk, pizza boxes, pizza slice trays and bag of cookies. It should be noted that the extraction for packages like cake/pastry boxes can be considered exaggerated, as the exposure usually is shorter. It can be hypothesised that the observed responses may be explained by inks, coatings, contaminants and/or naturally occurring compounds within the material. To summarise, an effect-based approach enables hazard identification of chemicals within FCMs, which is a valuable tool for ensuring safe use of FCMs.

description: Superluminal neutrinos are expected to lose energy due to bremstrauhlung. It is dominated by e+e--pair production if kinematically allowed. The same signature was used in searches for 3-body decays of hypothetical heavy sterile neutrinos. From the absence of these processes in CERN PS191 and CHARM experiments we set upper limits on the neutrino velocity in the energy range from 0.2 GeV to 280 GeV. Our limits are well below the neutrino velocity favored by the recent OPERA results. For energy-independent neutrino velocity the limits obtained in this paper are stronger than those coming from ICARUS experiment and observations of Supernova SN1987a.
One explanation for why farmers produce cotton collectively in post-Soviet Tajikistan
Creators: name: Kassam, Shinan N.
Publisher: name: University of British Columbia
Year: 2011

description: In post-Soviet Tajikistan, a heavy concentration on collective cotton production is argued to be based upon vested interests, a cash short economy, historical and political economy reasons. Given challenges in the set up of a functional land cadastral system, access to rural credit can be facilitated through the currency that raw cotton provides as collateral against production loans. While there are other relatively more profitable options for agricultural production, a certain amount of land is placed under cotton, in order to secure financing for non-cotton production. The lender advances credit for cotton production, but a portion of this credit is diverted out of cotton and into non-cotton production. Non-cotton production is not collateralized and results in a private gain for individual members within the “collective”. The lender has full knowledge of this diversion and compensates by pushing a higher level of in kind credit than is needed for the amount of land dedicated to cotton. Accumulating “debt” has become a defining feature of the cotton sector, but I argue that an appropriate definition is non conventional. This is particularly important given that loans are extended over consecutive seasons despite accumulating “debt”. “Debt” can more accurately be defined as the cost of doing business for the lender, who ties together the services of loan provision with that of marketing cotton. Using original copies of farm invoices, state statistics, key informant accounts, as well as secondary survey data, I argue that there is ostensibly little difference in the standard of living between farmers engaged in diversified cropping systems (cotton and non-cotton) and those engaged solely in non-cotton production. In an economy where markets for credit and productive inputs are thin and erratic, the manner in which credit is advanced plays a large role in fostering this indifference. This argument is somewhat different than the prevailing view, which takes the position that cotton “debt” is a constraining factor in the development of the agricultural sector in Tajikistan. One explanation for why Tajik farmers collectively produce cotton at a loss is that it is privately profitable to do so.
How Maternal, Family and Cumulative Risk Affect Absenteeism in Early Schooling: Facts for Policymakers

description: What is the role of the schooling experience in the educational trajectories and outcomes of children exposed to risk? Maternal and family risks are associated with greater absenteeism and the cumulative exposure to risk best predicts chronic absenteeism in early schooling. Kindergarten children in contact with three or more risks missed three or more days than their peers not facing any risks. But as children progress through the elementary grades, the impact of cumulative risk on school attendance lessens, only to rise again in the fifth grade. The most vulnerable children — those who are poor or racial/ethnic minorities or suffer from poor health — have the greatest exposure to cumulative risk.

description: Children represent 25 percent of the population. Yet, 41 percent of all children live in low-income families and nearly one in every five live in poor families. Our very youngest children, infants and toddlers under age 3, appear to be particularly vulnerable with 44 percent living in low-income and 22 percent living in poor families. Winding up in a low-income or poor family does not happen by chance. There are significant factors related to children's experiences with economic insecurity, such as race/ethnicity and parents' education and employment. This fact sheet describes the demographic, socio-economic, and geographic characteristics of infants and toddlers and their parents — highlighting the important factors that appear to distinguish low-income and poor children in this age group from their less disadvantaged counterparts.

description: Our aim in this review article is to present the applications of Connes' noncommutative geometry to elementary particle physics. Whereas the existing literature is mostly focused on a mathematical audience, in this article we introduce the ideas and concepts from noncommutative geometry using physicists' terminology, gearing towards the predictions that can be derived from the noncommutative description. Focusing on a light package of noncommutative geometry (so-called 'almost commutative manifolds'), we shall introduce in steps: electrodynamics, the electroweak model, culminating in the full Standard Model. We hope that our approach helps in understanding the role noncommutative geometry could play in describing particle physics models, eventually unifying them with Einstein's (geometrical) theory of gravity.

description: The dendritic cell (DC) vaccine anti-cancer strategy involves tumour-associated antigen loading and maturation of autologous ex vivo cultured DCs, followed by infusion into the cancer patient. This strategy stemmed from the idea that to induce a robust anti-tumour immune response, it was necessary to bypass the fundamental immunosuppressive mechanisms of the tumour microenvironment that dampen down endogenous innate immune cell activation and enable tumours to evade immune attack. Even though the feasibility and safety of DC vaccines have long been confirmed, clinical response rates remain disappointing. Hence, the full potential of DC vaccines has yet to be reached. Whether this cellular-based vaccination approach will fully realise its position in the immunotherapy arsenal is yet to be determined. Attempts to increase DC vaccine immunogenicity will depend on increasing our understanding of DC biology and the signalling pathways involved in antigen uptake, maturation, migration, and T lymphocyte priming to identify amenable molecular targets to improve DC vaccine performance. This review evaluates various genetic engineering strategies that have been employed to optimise and boost the efficacy of DC vaccines.

description: We prove several facts about the Yamabe constant of Riemannian metrics on general noncompact manifolds and about S. Kim's closely related "Yamabe constant at infinity". In particular we show that the Yamabe constant depends continuously on the Riemannian metric with respect to the fine C^2-topology, and that the Yamabe constant at infinity is even locally constant with respect to this topology. We also discuss to which extent the Yamabe constant is continuous with respect to coarser topologies on the space of Riemannian metrics.

Nelkin scaling for the Burgers equation and the role of high-precision calculations

description: Nelkin scaling, the scaling of moments of velocity gradients in terms of the Reynolds number, is an alternative way of obtaining inertial-range information. It is shown numerically and theoretically for the Burgers equation that this procedure works already for Reynolds numbers of the order of 100 (or even lower when combined with a suitable extended self-similarity technique). At moderate Reynolds numbers, for the accurate determination of scaling exponents, it is crucial to use higher than double precision. Similar issues are likely to arise for three-dimensional Navier--Stokes simulations.

Jet aerated loop reactors as alternative to stirred tank reactors

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt

Subjects: subject: 620

description: Strahlschlaufenreaktoren (JLRs) sind eine Alternative zum begasten Rührkessel (STR). Ein JLR erreicht bei gleichem Leistungseintrag um 200 % höhere Sauerstofftransferraten als ein mit Scheibenrührern betriebener Rührkessel. Basierend auf Erkenntnissen aus einem aeroben Fermentationsprozess werden in einem JLR rund doppelt so hohe Sauerstofftransfereffizienzen erreicht. Im Vergleich zum STR konnte der JLR bei 67 % höheren Sauerstofftransferraten betrieben werden. Infolge konnte die maximale Raum Zeit Ausbeute um 40% gesteigert werden. Es konnte gezeigt werden, dass mittels der herausragenden Massentransfereigenschaften des JLRs, höherer Umsätze erreicht, und Energie für Antrieb und Begasung eingespart werden können. In Hinblick auf die Produktionskosten ist die Massentransfereffizienz allerdings nur ein Parameter unter Vielen. Obwohl die OTRs um 100 % gesteigert und der Massentransfer energieeffizienter generiert wurde, konnte lediglich ein Einsparpotential von 5.6 % ermittelt werden.
description: Jet loop reactors (JLRs) are an alternative reactor type for stirred tank reactors (STR). Compared to a stirred tank reactor powered by Rushton turbines, maximum oxygen transfer rates (OTRs) about 200 % higher were achieved in a jet loop reactor in a fed batch fermentation process. The assessment of the energetic oxygen transfer efficiency for a jet loop reactor yielded an improvement of almost 100 %. The jet loop reactor could be operated at mass transfer rates 67 % higher compared to a stirred tank. Thus, an increase of 40 % in maximum space time yield could be observed. It can be concluded that the outstanding mass transfer performance of JLRs helps to increase turnover rates and to save energy for agitation and aeration. However, mass transfer efficiency is only one parameter among multiple aspects with relevance for production costs. Even though OTRs could be increased by 100 % and the mass transfer was generated at an increased energy efficiency, only a cost advantage of 5.6 % was calculated.
