This study tests the hypothesis that undergraduates who peer teach genetics will have greater understanding of genetic and molecular biology concepts as a result of their teaching experiences. Undergraduates enrolled in a non–majors biology course participated in a service-learning program in which they led middle school (MS) or high school (HS) students through a case study curriculum to discover the cause of a green tomato variant. The curriculum explored plant reproduction and genetic principles, highlighting variation in heirloom tomato fruits to reinforce the concept of the genetic basis of phenotypic variation. HS students were taught additional activities related to mole­cular biology techniques not included in the MS curriculum. We measured undergraduates’ learning outcomes using pre/postteaching content assessments and the course final exam. Undergraduates showed significant gains in understanding of topics related to the curriculum they taught, compared with other course content, on both types of assessments. Undergraduates who taught HS students scored higher on questions specific to the HS curriculum compared with undergraduates who taught MS students, despite identical lecture content, on both types of assessments. These results indicate the positive effect of service-learning peer-teaching experiences on undergraduates’ content knowledge, even for non–science major students.

Frequency trend attribute analysis for stratigraphic division and correlation
Authors: Xu Jingling , Liu Luofu , Qin Yuxing , Zhang Jianbo
Published: December 2014

Stratigraphic sequence interpretation and correlation are part of basic geologic research, but present frequent problems such as subjective and accurate division and correlation of sequence cycles, and a multiplicity of solutions to high-frequency sequences. We developed a novel method, termed frequency trend attribute analysis (FTAA), to solve these problems and improve the accuracy of division. The method was based on maximum entropy spectrum analysis data, built on theoretical foundations, and tested on geologic models as well as empirical data. We developed examples of how FTAA can improve stratigraphic division and correlation. We extracted frequency trend lines from well logging data (using all or a selected part of a facies-sensitive log such as the natural gamma-ray log) whereby the FTAA outcome reflected the overlay series and cycle structures. The resulting frequency trend lines also indirectly reflected changes to the sedimentary environment and base level, and the precise stratigraphic division and isochronous comparisons were automatically deduced from the frequency trend lines. According to the practical comparison with wells in the field, the frequency trend lines were found to be more accurate than using outcrop data, and the method proved to be effective and convenient in use. The FTAA significantly improved the precision and accuracy of automatic division and correlation of sequence cycles.

Published: December 2014

Background

Agitation in dementia is common, persistent and distressing and can lead to care breakdown. Medication is often ineffective and harmful.

Aims

To systematically review randomised controlled trial evidence regarding non-pharmacological interventions.

Method

We reviewed 33 studies fitting predetermined criteria, assessed their validity and calculated standardised effect sizes (SES).

Results

Person-centred care, communication skills training and adapted dementia care mapping decreased symptomatic and severe agitation in care homes immediately (SES range 0.3–1.8) and for up to 6 months afterwards (SES range 0.2–2.2). Activities and music therapy by protocol (SES range 0.5–0.6) decreased overall agitation and sensory intervention decreased clinically significant agitation immediately. Aromatherapy and light therapy did not demonstrate efficacy.

Conclusions

There are evidence-based strategies for care homes. Future interventions should focus on consistent and long-term implementation through staff training. Further research is needed for people living in their own homes.
Sustainable psychiatry in the UK
Authors: Yarlagadda Sucharita , Maughan Daniel , Lingwood Susie , Davison Phil
Published: December 2014

Demands on our mental health services are growing as financial pressures increase. In addition, there are regular changes to service design and commissioning. The current political mantra is ‘more and more, of better quality, for less and less, please’. We suggest that mental health services need to actively respond to these constraints and that clinical transformation is needed to move towards a more sustainable system of healthcare. Emphasis on prevention, patient empowerment and leaner, greener services is required alongside more extensive use of technologies. Focusing on these areas will make mental health services more responsive to the challenges we face and serve to future-proof psychiatry in the UK. Services need to be delivered to provide maximum benefit to the health of our patients, but also to our society and the environment.
Play-Acting in Hoffmann'sPrinzessin Brambilla
Authors: Burwick Frederick
Published: December 2014

In Prinzessin Brambilla Hoffmann combines his study of mental pathology with his involvement in theater performance. Hoffmann introduces figures of the commedia dell'arte as street players in the midst of carnival. The derangement of Giglio Favia, an actor, is played out amidst the paradigm shift from the Classic to the Romantic. As in his other tales with delusional protagonists, Hoffmann draws from contemporary mental pathology, not just in constructing character but also in adapting medical case studies as narrative models. The revival of commedia dell'arte and the staging of fable and the harlequinades introduced modes of multiple role-playing on the stage. Hoffmann found in Johann Christian Reil and Gotthilf Heinrich Schubert strong advocates for play-acting as a cure for madness. Locating that opportunity in the disguises of carnival, Hoffmann has the mountebank pathologist Celionati guide the impressionable Giglio out of his delirium by means of play-acting in a fairy tale.
On the Lack of Curiosity Regarding Institutional Life
Authors: Hayot Eric
Published: December 2014

Do we think that ideas only come in a limited number of sizes? Obviously not. And yet … it would be perfectly reasonable for someone from the outside to accuse us of so thinking. These are the constraints of the institution, and we reinforce them constantly: in, for instance, our evaluations of journal articles, including the ways we count them for tenure; but also, say, in the normal length of the normal end-of-term graduate seminar paper, which is merely a proxy for its potential future as a journal article. And so for historical periods, the graduate curriculum, and reports on the state of disciplines: we think very badly about institutions, when we do at all.
The Micropolitics of Fascism in Carson McCullers's The Heart Is a Lonely Hunter and Sinclair Lewis's It Can't Happen Here
Authors: Kaiser Wilson
Published: December 2014

Malcolm Cowley's claim that American literature has never dealt with the question of fascism is a key moment in the separation of literary studies and politics. Arguing that politics is too ideological and crude to grapple with the nuances of the text, Cowley cites Carson McCullers's The Heart Is a Lonely Hunter (1940) as a primary example of what politics cannot express. This essay takes up McCullers's novel as a case study, contrasting it with Sinclair Lewis's antifascist It Can't Happen Here (1935). Rather than treating fascism as an ideologically monolithic phenomenon, however, I draw on recent research that has turned to the private concerns of everyday life, or micropolitics, under fascist regimes. McCullers's emphasis on the micropolitical dimension of small-town American life echoes these recent insights in fascism studies, demonstrating the evident transatlantic context of American life at the everyday level and the pervasive concerns about fascism in the 1930s. In contrast to Lewis's crudely political novel, micropolitical literature like McCullers's novel is in a special position to provide insights into the quotidian struggle to characterize and respond to large-scale political developments, providing new avenues for investigating the commonplace dynamics that eventually well up into official history and ideologically driven politics.
Porous Cels
Authors: Rosskam Jules
Published: December 2014

I use my most recent film, Thick Relations, to argue that traditional narrative structures are by definition oppressive and controlling. Traditional narratives demand a straight progress through time, through life, through love, through sexuality and conflict and family—a straight progress that would have us believe in and desirous of state-sanctioned institutions and relations. Queer lives don't make sense. We are not supposed to be alive, to love the people we love, to live in our bodies so creatively. And it is precisely this confusion—this nonsense—that I seek to preserve for the ways that it exposes and rejects normativity. I believe we need to hold onto, acknowledge, and celebrate this otherness, not because we thrive on being contrarian, but because the regimes of normality are the forces that seek to obliterate us. We must resist in order to survive.

Trauma and orthopaedics is the largest of the surgical specialties and yet attracts a disproportionately small fraction of available national and international funding for health research. With the burden of musculoskeletal disease increasing, high-quality research is required to improve the evidence base for orthopaedic practice. Using the current research landscape in the United Kingdom as an example, but also addressing the international perspective, we highlight the issues surrounding poor levels of research funding in trauma and orthopaedics and indicate avenues for improving the impact and success of surgical musculoskeletal research.

Clinical outcome of pedestal cup endoprosthetic reconstruction after resection of a peri-acetabular tumour
Authors: Bus M. P. A. , Boerhout E. J. , Bramer J. A. M. , Dijkstra P. D. S.
Published: December 2014

Peri-acetabular tumour resections and their subsequent reconstruction are among the most challenging procedures in orthopaedic oncology. Despite the fact that a number of different pelvic endoprostheses have been introduced, rates of complication remain high and long-term results are mostly lacking.

In this retrospective study, we aimed to evaluate the outcome of reconstructing a peri-acetabular defect with a pedestal cup endoprosthesis after a type 2 or type 2/3 internal hemipelvectomy.

A total of 19 patients (11M:8F) with a mean age of 48 years (14 to 72) were included, most of whom had been treated for a primary bone tumour (n = 16) between 2003 and 2009. After a mean follow-up of 39 months (28 days to 8.7 years) seven patients had died. After a mean follow-up of 7.9 years (4.3 to 10.5), 12 patients were alive, of whom 11 were disease-free. Complications occurred in 15 patients. Three had recurrent dislocations and three experienced aseptic loosening. There were no mechanical failures. Infection occurred in nine patients, six of whom required removal of the prosthesis. Two patients underwent hindquarter amputation for local recurrence.

The implant survival rate at five years was 50% for all reasons, and 61% for non-oncological reasons. The mean Musculoskeletal Tumor Society score at final follow-up was 49% (13 to 87).

Based on these poor results, we advise caution if using the pedestal cup for reconstruction of a peri-acetabular tumour resection.

The Histone H3 Lysine 9 Methyltransferase DIM-5 Modifies Chromatin at frequency and Represses Light-Activated Gene Expression
Authors: Ruesch Catherine E , Ramakrishnan Mukund , Park Jinhee , Li Na , Chong Hin S , Zaman Riasat , Joska Tammy M , Belden William J
Published: December 2014

The transcriptional program controlling the circadian rhythm requires coordinated regulation of chromatin. Characterization of the chromodomain helicase DNA-binding enzyme CHD1 revealed DNA methylation in the promoter of the central clock gene frequency (frq) in Neurospora crassa. In this report, we show that the DNA methylation at frq is not only dependent on the DNA methyltransferase DIM-2 but also on the H3K9 methyltransferase DIM-5 and HP1. Histone H3 lysine 9 trimethylation (H3K9me3) occurs at frq and is most prominent 30 min after light-activated expression. Strains lacking dim-5 have an increase in light-induced transcription, and more White Collar-2 is found associated with the frq promoter. Consistent with the notion that DNA methylation assists in establishing the proper circadian phase, loss of H3K9 methylation results in a phase advance suggesting it delays the onset of frq expression. The dim-5 deletion strain displays an increase in circadian-regulated conidia formation on race tubes and there is a synthetic genetic interaction between dim-5 and ras-1bd. These results indicate DIM-5 has a regulatory role in muting circadian output. Overall, the data support a model where facultative heterochromatic at frq serves to establish the appropriate phase, mute the light response, and repress circadian output.
Percutaneous coronary intervention in stable coronary artery disease
Authors: Piróth Zsolt
Published: December 2014

Percutaneous coronary intervention is a well-established symptomatic therapy of stable coronary artery disease. Using a literature search with special emphasis on the newly-published FAME 2 trial data, the author wanted to explore why percutaneous coronary intervention fails to reduce mortality and myocardial infarction in stable coronary artery disease, as opposed to surgical revascularisation. In the FAME 2 trial, fractional flow reserve-guided percutaneous coronary intervention with second generation drug eluting stents showed a significant reduction in the primary composite endpoint of 2-year mortality, myocardial infarction and unplanned hospitalization with urgent revascularisation as compared to medical therapy alone. In addition, landmark analysis showed that after 8 days, mortality and myocardial infarction were significantly reduced. The author concludes that percutaneous coronary intervention involving fractional flow reserve guidance and modern stents offers symptomatic, as well as prognostic benefit. Orv. Hetil., 2014, 155(49), 1952–1959.
Relationship between early maladaptive schemas, attachment quality and fear of darkness
Authors: Kopcsó Krisztina , Láng András
Published: December 2014

Introduction: Although fear of darkness is most common in childhood, it is also a remarkable phenomenon in young adulthood. Aim: To examine the relationship between fear of darkness, early maladaptive schemas and attachment quality in young adults and assess fear related sex differences. Method: A self-developed scale was used to measure fear of darkness’ intensity and frequency. Young Schema Questionnaire – Short Form and two scales that measure attachment dimensions were also applied. 120 university students (68 women, 52 men) filled in the tests. Results: Fear of darkness’ frequency correlated with avoidant attachment, and intensity with independent and anxious attachment. Fear of darkness variables correlated with several early maladaptive schemas. Women reported more frequent and intensive fear of darkness than men. Conclusions: These results indicated that the elevated level of fear of darkness is related to specific cognitive style and attachment quality. This highlights the potential clinical relevance of fear of darkness. Orv. Hetil., 2014, 155(49), 1967–1972.

Objective.

No consensus has been reached on sexual dysfunction in men with ankylosing spondylitis (AS). Our study aimed to derive a more precise estimation of the sexual function and its clinical correlations in men with AS.

Methods.

A metaanalysis was performed and the related literature were searched in PubMed, Elsevier Science Direct, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and in reference lists of articles and systematic reviews. Score of the International Index of Erectile Function (IIEF) was used as the outcome measurement, and standardized mean differences (SMD) with 95% CI were calculated.

Results.

Eleven studies were included, including 535 men with AS and 430 male controls. Each domain of the IIEF score (erectile function: SMD −0.52, 95% CI −0.68 – −0.37; orgasmic function: −0.72, −1.03 – −0.42; sexual drive: −0.40, −0.62 – −0.18; intercourse satisfaction: −0.86, −1.15 – −0.56; and overall satisfaction: −0.61, −0.91 – −0.32) were lower in men with AS than in controls. In the subgroup analysis, the results did not change except for the sexual drive in the Asians group (−0.15, −0.42–0.13). At metaregression, no study characteristics were significantly associated with effect size of the IIEF score.

Conclusion.

Sexual function is impaired in male patients with AS and further studies are necessary to better understand risk factors for sexual dysfunction in this population.

Literary comparisons and contrasts in Mark 5:21−43
Authors: Branch Robin Gallaher
Published: December 2014

This article examines a number of comparisons and contrasts in Mark 5:21–43, stories of two different kinds of healing that took place one morning when Jesus returned to Capernaum from the region of the Gerasenes (Mk 5:1, 21). The interlocking stories of the woman with the constant issue of haemorrhage and the restoration to life of the gravely ill and then dead daughter of Jairus, a synagogue ruler, invite literary and canonical examinations. The article also briefly discusses the significance of the unnamed groups of characters in the stories and compares the complementary versions of the stories amongst Matthew, Mark and Luke. The two miracles exhibit different aspects of Jesus’ amazing power and contribute to the ongoing portrayal of Jesus in Mark as the Son of God (Mk 1:1).Literêre vergelykings en kontraste in Markus 5:21−43. Hierdie artikel ondersoek ’n aantal vergelykings sowel as verskille in Markus 5:21−43 soos blyk uit die verhale van twee verskillende gevalle van genesing wat een oggend tydens Jesus se terugkeer uit die gebied van die Geraseners na Kapernaum plaasgevind het (Mark 5:1, 21). Die onderlinge verhale van die vrou wat aan bloedvloeiing gely het en van die genesing van die ernstige siek en later afgestorwe dogtertjie van Jaïrus, een van die raadslede van die sinagoge, leen dit tot’n literêre en kanonieke ondersoek. Die artikel bespreek ook kortliks die beduidende betekenis van die ongeïdentifiseerde groepe mense in albei verhale. Die verskillende weergawes van die verhale soos in Matteus, Markus en Lukas opgeteken, word ook bespreek. Hierdie twee wonderwerke openbaar die verskillende aspekte van Jesus se verstommende mag en dra by tot die volgehoue uitbeelding van Hom in Markus as die Seun van God (Mark 1:1).

Day surgery in a teaching hospital: identifying barriers to productivity
Authors: Salih Abdelmonim E. A , Meshkat Babak , A Bass Gary , McHugh Seamus , Fox Sinead , N Walsh Thomas
Published: December 2014

Introduction: Ambulatory surgery is a standard of care for many surgical procedures due to cost-effectiveness and benefits to patients including the reduced risk of contracting hospital infection by reducing the hospital stay. However, late cancellations can be costly. We examined the utilisation of the surgical day ward in our institution over a four-year period. Methods: A retrospective study of surgical day ward records from September 2007 to September 2011 in one institution. Parameters investigated included the number of planned admissions. Reasons for cancellations were also collected. Results: A total of 17,461 procedures were intended as a day ward admission during the study interval. There were 3,539 procedures that were cancelled (20.3%). The prevalent proportion of cancellations (n = 1,367) (38.6%) were due to patients not showing up for their procedures (7.8% of planned admissions); 1,188 (33.6%) patients were cancelled by the admissions office due to bed shortages, accounting for 6.8 % of planned admissions and 650 (18.4%) of cases were due to last minute cancellations by patients, accounting for 3.7% of all planned admission. The remaining 334 (9.4%) of cases were cancelled on medical grounds including patients who were considered unfit for the intended procedure, or anti-coagulations not appropriately ceased prior to surgery, accounting for 1.9% of all planned admissions. Conclusion: The cancellation rate in this study was high, mainly due to failure of patients to attend or signal their intentions, inadequate bed capacity and bed closure strategies. The ring fencing and protection of day beds and a more active patient management interaction would have had the greatest impact on increased efficiency.
Soufisme et utopie économico-religieuse : les entrepreneurs mourides sénégalais à l’« assaut » des métropoles occidentales
Authors: Sall Leyla
Published: December 2014

L’article retrace la genèse et l’évolution de l’utopie religieuse de la confrérie soufie mouride du Sénégal. Une telle utopie mise en place en contexte colonial et rural s’est largement transformée pour être opératoire en contexte urbain et migratoire. Elle permet aux migrants entrepreneurs mourides d’avoir confiance en soi dans leur « conquête symbolique » de l’Occident.

S’appuyant sur une mystique du travail de type religieux, l’utopie religieuse mouride n’en est pas moins efficace. Elle a permis le succès entrepreneurial des mourides, mais aussi l’extraterritorialité de leur capitale religieuse qui, désormais, bénéficie de politiques sociales et de projets urbains dans lesquels l’État sénégalais joue un rôle marginal.
Militer par l’action commerciale ? Biocoop et l’agriculture biologique française
Authors: Anzalone Guilhem
Published: December 2014

Issu des mouvements écologistes et alternatifs, le réseau de magasins indépendants Biocoop se donne pour objectif de militer pour un projet de société à travers la distribution de produits biologiques. En centrant l’analyse sur les dispositifs mobilisés dans le réseau, l’article montre comment les outils de gestion incorporent et concrétisent des principes de valeur. Cette dimension politique se caractérise également par une certaine ambivalence qui se répercute au sein de la structure ; elle se traduit notamment par l’hétérogénéité des organisations et des pratiques. Le projet de Biocoop s’étend aussi à la circulation des produits, où son intervention est mise à l’épreuve dans la gouvernance des filières. L’étude de ce cas explore ainsi les multiples manifestations de la dimension politique de l’activité économique ordinaire.
Les refigurations de notre expérience du temps
Authors: Desmeules Marie-Hélène
Published: December 2014

Contre l’idée d’un temps fixe enveloppant notre expérience, les travaux de Paul Ricoeur nous permettent de penser que non seulement notre expérience du temps n’est pas si fixe qu’elle n’y paraît, mais qu’elle est en outre transformée par des refigurations découlant de nos médiations objectives. Ces médiations objectives ne se limitent pas à la narration, mais couvrent également l’amnistie, la prescription, la promesse, le pardon et les objets de notre monde familier. Chacune à leur façon, les médiations examinées opèrent une synthèse du passé, du présent et du futur, au point de bouleverser le temps chronologique et successif du courant de la conscience. Ultimement, nous prendrons les réflexions de Paul Ricoeur comme ressources pour penser les implications éthiques des transformations de notre expérience du temps. Car chaque expérience du temps n’ouvre et ne ferme pas les mêmes possibilités, comme le rapport entre le pardon et l’homme capable devrait le montrer.

Published: December 2014

The use of surface waters such as rivers for domestic, agricultural andindustrial purposes have made them vulnerable to pollution leading to impairedwater quality. The water quality of Lahug River in Cebu City was evaluated usingcoliforms as indicators, in relation with physicochemical parameters such as biological oxygen demand (BOD), conductivity, dissolved oxygen (DO), nitrate,pH, phosphate, salinity, temperature, total dissolved solids (TDS) and totalsuspended solids (TSS). Sampling was done once a month from November 2011to April 2012 in three stations covering the upstream, midstream and downstream.The multiple tube fermentation technique was used for the analysis of coliforms.The level of these indicator bacteria increased from the upstream towards thelower reaches of the river especially in the months of February to April; however,the difference in values across time was not significant. This implies that therewas a continuous fecal pollution in the river. There were no statistically significantcorrelations between FCs and TCs with the physicochemical parameters. Anegative relationship was observed among FCs and TCs with pH, TSS, DOand nitrate (p>0.05). These results suggest the presence of sewage and organicpollutants in the river.Keywords: Aquatic Ecology, water quality, coliform, physicochemical parameters,experimental design, Philippines

Multiple Shoot Induction of Asparagus (Asparagus Officinalis Var. Uc-157) Through Nodal Stem Culture Technique
Authors: PASCUAL PET ROEY L.
Published: December 2014

Multiple shoot induction is a powerful tool for mass propagation of promisingclones and is essential to asparagus due to its dioecious nature. Along this line anexperimental research conducted to determine the most effective plant growth regulators(PGRs) that would induce multiple shoot formation from asparagus nodalstem explants using agar-solidified Murashige and Skoog (MS) basal medium. Fourcombinations of kinetin or benzyl amino purine (BAP) and naphthalene acetic acid(NAA), arranged in Randomized Complete Block Design, served as treatments withhormone-free MS medium as control. Treatment means were compared using Duncan’sMultiple range Test (DMRT). Only medium supplemented with PGRs initiatedshoots. Among the treatments, the medium containing 0.5 mg/L kinetin and0.1 mg/L NAA, or 0.5 mg/L BAP and 0.1 mg/L NAA significantly induced thehighest percentage (100%) shoots from cultured explants after 15.27 and 22.97 days,respectively. The same PGR combinations produced an average of 3-4 shoots per explantsafter eight weeks of culture. The medium supplemented with 0.5 mg/L kinetinand 0.1 mg/L NAA produced longer shoots (4.64 cm) of which 10% produced roots.This PGR combination is recommended since produced the best shoot attributes andlikewise shorten the duration of in vitro culture.Keywords: Botany, plant tissue culture, multiple shoot induction, experimental design,Cebu City, Philippines

As a climate change adaptation strategy, most ofthe participants prepare equipment for mobilization and build solid and firminfrastructures. The respondents consider themselves knowledgeable on climatechange adaptation because of their attendance at trainings and workshops. Duringevacuation, priority is given to elderly and children. They also collaborate withconcerned organizations whenever there is a typhoon. Community practicesduring possible flooding include evacuation, securing of property, preparation ofmaterials to protect houses, and strengthening of sea dike. Community membersare affiliated with an organization. Assistance extended to the coastal communitiescentered on disaster prevention, fortification of houses, and evacuation, which isthe utmost priority of the coastal communities during typhoon and flooding.Collaboration with networks is more evident among coastal communities whena strong typhoon is coming than when there is flooding.Keywords: Climate change adaptation, social capital, networks, case study approach,Vietnam

Lobster (Panulirus sp.) is an expensive priced marine crustacean both in localand international markets. The study was conducted to determine the abundance,ecology and fishery of lobster in Buenavista, Guimaras and their contribution tothe socio-economic condition of the fisher folks. The study used the descriptiveresearch design. The respondents of the study were the lobster fisher folks. Thedata gathered are composed of volumes of catch as to male and female, catch sizeduring lean and peak seasons, ecology of the area and socio-economic conditionof the fisher folks. The statistical tools used were frequency, percent, ranking and Pearson r. Spiny tiger lobster habituated most the area and many of themare male. The plankton was abundant, salinity during the peak seasons rangesfrom 16ppt to 31 ppt and 28ppt to 32 during lean seasons. The temperature was almost the same for both seasons with the average of 29104oC. Water was more turbid during the lean season and the depth of seawater ranges from 36 ft to 64ft.Majority of the fisher folk earned a monthly income of Php5,000.00 and below,despite the socio-economic condition which is not good based on the NationalEconomic Development Authority (NEDA) economic threshold level.Keywords: Ecology, abundance, lobster fishery, descriptive design, Philippines
Determination of the Cytostatic and Cytocidal Activities of Antimalarial Compounds and Their Combination Interactions
Authors: Sherlach Katy S. , Roepe Paul D.
Published: December 2014

Determining the antiplasmodial activity of candidate antimalarial drugs in vitro identifies new therapies for drug‐resistant malaria. Importantly though, activity can be either growth‐inhibitory (cytostatic) or parasite‐kill (cytocidal), or both. The simple methods described here can allow for distinction between these activities, as well as definition of drug interactions between two or more compounds. The latter is important in the definition of novel drug combination therapy for malaria. These methods involve live malarial parasite red blood cell culture, routine pharmacology, high‐throughput detection of parasite DNA with fluorescent reporters, and routine mathematical analysis of dose‐response curves. The techniques and approaches are accessible to most laboratories and require minimal special equipment beyond a fluorescent plate reader and tissue culture facilities. © 2014 by John Wiley & Sons, Inc.

Long Range Dependence
Authors: Samorodnitsky Gennady
Published: December 2014

Long‐range dependence (synonymous with
long memory
) is a property of some stationary processes. Intuitively, the notion is clear: a stationary stochastic process that has long‐range dependence is a process whose memory lasts very long. However, the term ‘long‐range dependence’ means more than simply ‘longer memory’. It means memory so long that the behavior of a stochastic process changes dramatically, and so long that the usual statistical tools break down when applied to observations arising from a long‐range dependent process.

Seymour Geisser was a leading proponent of the importance of prediction in the practice of statistics, as well as a leading exponent of multivariate analysis. He pioneered several important areas of statistical endeavor, such as the now popular method for validating statistical models called cross‐validation, and the equivalent method of predictive sample reuse. He also pioneered the areas of Bayesian multivariate analysis and discrimination, Bayesian diagnostics for statistical prediction and estimation models, Bayesian interim analysis, and testing for Hardy–Weinberg equilibrium using forensic DNA data.
Magnetic Liquid Marbles: Toward “Lab in a Droplet”

Liquid marbles exhibit great potential for use as miniature labs for small‐scale laboratory operations, such as experiment and measurement. While important progress has been made recently in exploring their applications as microreactions, “on‐line” measurement of the components inside the liquid still remains a challenge. Herein, it is demonstrated that “on‐line” detection can be realized on magnetic liquid marbles by taking advantage of their unique magnetic opening feature. By partially opening the particle shell, electrochemical measurement is carried out with a miniaturized three‐electrode probe and the application of this technique for quantitative measurement of dopamine is demonstrated. Fully opened magnetic liquid marble makes it feasible to detect the optical absorbance of the liquid in a transmission mode. With this optical method, a glucose assay is demonstrated. Moreover, when magnetic particle shell contains low melting point material, e.g., wax, the liquid marble shows a unique encapsulation ability to form a rigid shell after heating, which facilitates the storage of the non‐volatile ingredients. These unique features, together with the versatile use as microreactors, enable magnetic liquid marbles to function as a miniature lab (or called “lab in a droplet”), which may find applications in clinical diagnostics, biotechnology, chemical synthesis, and analytical chemistry.

Published: December 2014

Numerical simulation is an effective method to get the optimal operating parameters in the chemical engineering process. In this work, the transport mechanism of vacuum membrane distillation (VMD) process was simulated and predicted by mathematical model, which was established based on the convective heat transfer coefficient, and 0.5M aqueous NaCl solution was concentrated with isotactic polypropylene (iPP) hydrophobic microporous membrane prepared via thermally induced phase separation (TIPS) in the VMD process. The as‐presented mathematical model simulated the effects of different operating parameters on the VMD performances for aqueous NaCl solution, such as feed temperature, feed flow rate, absolute pressure of membrane permeate side, temperature coefficient, membrane thickness, and porosity. A comparison between experimental data and simulated data was also considered to verify the proposed mathematical model. Additionally, the salt rejection of aqueous NaCl solution production water in VMD was higher than 99.9%. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41632.
Synthesis of pyridinium polysiloxane for antibacterial coating in supercritical carbon dioxide

Published: December 2014

Antibacterial polysiloxane with pyridinium pendants was synthesized through hydrosilylation reaction of trimethylsiloxane terminated (45% methylhydrosiloxane)–dimethylsiloxane random copolymer and 4‐vinylpyridine and subsequent N‐alkylation of pyridine ring with 1‐bromohexane. The pyridinium polysiloxane was coated on cotton and formed a 35 nm layer via a novel method of deposition in supercritical carbon dioxide (scCO2) for biocidal application. The coated fabrics provided effective antibacterial activities against both Staphylococcus aureus and Escherichia coli compared with uncoated ones that did not exhibit noticeable biocidal activities. The pyridinium polysiloxane coating layer on cotton was stable toward storage in air and washing cycles. The scCO2 deposition technique uses ecologically responsible CO2 as solvent and is hypothesized to work on both reactive and nonreactive surfaces due to without the use of covalent tethering groups. © 2014 Wiley Periodicals, Inc.

Published: December 2014

Verbunddübelleisten sind leistungsfähige, neuartige Verbundmittel für den Stahl‐Verbundbau, die bisher vor allem in Ingenieurbauwerken wie z. B. vorgefertigten Verbundbrücken eingesetzt werden. Aufgrund ihrer einfachen Herstellung bei oberflanschlosen Stahlprofilen, ihren guten Trag‐ und Verformungseigenschaften sowie ihrer Anwendbarkeit in schlanken Betongurten werden Verbunddübelleisten zunehmend auch im Hoch‐ und Geschossbau verwendet. Der vorliegende Beitrag beschreibt Abscherversuche an einer puzzleförmigen Verbunddübelleiste für flache Betongurte mit einer Dicke von lediglich 10 cm. Als Haupteinflussparameter werden verschiedene Längsspannungszustände im Betongurt bei unterschiedlichen Bewehrungsführungen untersucht, wofür ein eigener Versuchsstand entwickelt wurde. Während in den bisherigen Ansätzen zur Bemessung der statischen Schubtragfähigkeit von Verbunddübelleisten keine Tragfähigkeitsminderung für quergerissene Betongurte vorgesehen wird, zeigen die vorgestellten Versuche mit schlanken Betongurten einen nennenswerten Einfluss der Betonrissbildung auf die Verbundmittelbruchlast. Die durchgeführten Versuche wurden mithilfe eines dreidimensionalen, nicht‐linearen Finite‐Elemente‐Modells simuliert und analysiert.

Influence of transversal cracking on the shear load bearing behavior of composite dowels in slender concrete chords

Composite dowels are efficient, innovative shear connectors for use in engineering structures such as prefabricated composite bridges. Due to their ease of production in steel profiles with single‐flange, their good load bearing and deformation properties and their applicability in slender concrete chords, composite dowels are increasingly being used in building construction. This paper describes push‐out tests on puzzle‐ shaped composite dowels for slender concrete chords with a thickness of only 10 cm. Besides different variants of reinforcement, in particular the influence of different longitudinal stress states and transverse cracking in the concrete slab has been explored. For this purpose an appropriate test setup has been developed. In previous approaches for the static shear strength of composite dowels, the influence of transverse cracking is neglected. However, the presented experiments with slender concrete chords show a significant effect of concrete cracking on the composite dowels' shear carrying capacity. The presented experiments were simulated and analyzed by a three‐dimensional, non‐linear finite element model of the push‐out tests.
