A Bayesian destructive weighted Poisson cure rate model and an application to a cutaneous melanoma data
Authors: Rodrigues Josemar , Cancho Vicente G , de Castro Mário , Balakrishnan N
Published: December 2010

In this article, we propose a new Bayesian flexible cure rate survival model, which generalises the stochastic model of Klebanov et al. [Klebanov LB, Rachev ST and Yakovlev AY. A stochastic-model of radiation carcinogenesis – latent time distributions and their properties. Math Biosci 1993; 113: 51–75], and has much in common with the destructive model formulated by Rodrigues et al. [Rodrigues J, de Castro M, Balakrishnan N and Cancho VG. Destructive weighted Poisson cure rate models. Technical Report, Universidade Federal de São Carlos, São Carlos-SP. Brazil, 2009 (accepted in Lifetime Data Analysis)]. In our approach, the accumulated number of lesions or altered cells follows a compound weighted Poisson distribution. This model is more flexible than the promotion time cure model in terms of dispersion. Moreover, it possesses an interesting and realistic interpretation of the biological mechanism of the occurrence of the event of interest as it includes a destructive process of tumour cells after an initial treatment or the capacity of an individual exposed to irradiation to repair altered cells that results in cancer induction. In other words, what is recorded is only the damaged portion of the original number of altered cells not eliminated by the treatment or repaired by the repair system of an individual. Markov Chain Monte Carlo (MCMC) methods are then used to develop Bayesian inference for the proposed model. Also, some discussions on the model selection and an illustration with a cutaneous melanoma data set analysed by Rodrigues et al. [Rodrigues J, de Castro M, Balakrishnan N and Cancho VG. Destructive weighted Poisson cure rate models. Technical Report, Universidade Federal de São Carlos, São Carlos-SP. Brazil, 2009 (accepted in Lifetime Data Analysis)] are presented.
Stakeholder perspectives and reactions to “academic” cognitive enhancement: Unsuspected meaning of ambivalence and analogies
Authors: Forlini Cynthia , Racine Eric
Published: December 2010

The existence of diverging discourses in the media and academia on the use of prescription medications to improve cognition in healthy individuals, i.e. “cognitive enhancement” (CE) creates the need to better understand perspectives from stakeholders. This qualitative focus-group study examined perspectives from students, parents and healthcare providers on CE. Stakeholders expressed ambivalence regarding CE (i.e. reactions to, definitions of, risks, and benefits). They were reluctant to adopt analogies to performance-enhancing steroids and caffeine though these analogies were useful in discussing concepts common to the use of different performance-enhancing substances. Media coverage of CE was criticized for lack of scientific rigor, ethical clarity, and inadvertent promotion of CE. Ambivalence of stakeholders suggests fundamental discomfort with economic and social driving forces of CE. Forms of public dialogue that voice the unease and ambivalence of stakeholders should be pursued to avoid opting hastily for permissive or restrictive health policies for CE.
Descriptive Study of Shared Decision Making About Lifestyle Modifications With Individuals Who Have Psychiatric Disabilities
Authors: Hamera Edna , Pallikkathayil Leonie , Baker Donna , White Dena
Published: December 2010

BACKGROUND: Shared decision making (SDM) is a process of active participation by clients with practitioners in weighing the risks and benefits of treatments. It has not been extended to decisions about making lifestyle modifications. OBJECTIVE: Describe how frequently health lifestyle behaviors are addressed in 15- to 20-minute medicine clinic visits with individuals who have psychiatric disabilities and how often SDM is used in reaching decisions. DESIGN: Content analysis of 98 audiotaped transcripts from practitioner and client medicine clinic visits. RESULTS: The most frequently discussed lifestyle behaviors discussed were sleep (89%) and diet (61%). SDM, defined as sharing information and options about behavior by either or both practitioner and client and affirmation of a decision by both, occurred 48 times (44%) when a problem existed. CONCLUSION: Discussion of lifestyle behaviors along with use of SDM in negotiating changes in behavior is feasible in a 15- to 20-minute visit.
A general method for modeling on irregular grids
Authors: MacDonald Alexander E. , Middlecoff Jacques , Henderson Tom , Lee Jin-Luen
Published: December 2010

For simulation on a spherical surface, such as global numerical weather prediction, icosahedral grids are superior to their competitors in uniformity of grid mesh distance across the entire globe and lack of neighboring grid cells that share only a single vertex. Use of such a grid presents unique programming challenges related to iteration across grid cells and location of neighboring cells. Here we describe an icosahedral grid with a one-dimensional vector loop structure, table specified memory order, and an indirect addressing scheme that yields very compact code despite the complexities of this grid. This approach allows the same model code to be used for many grid structures. Indirect addressing also allows grid cells to be stored in any order, selectable at run time. This permits easy implementation of different memory layouts for cache blocking, distributed-memory parallelism, and static load balancing. Since indirect addressing can adversely affect execution time we organize arrays to place a directly addressable index innermost. We also describe experiments designed to measure any performance penalties accrued from use of indirect addressing.
A Meta-Analysis of Organizational Complaint Handling and Customer Responses
Authors: Gelbrich Katja , Roschk Holger
Published: December 2010

Service recovery is a crucial success factor for organizations. Thus, many studies have addressed the issue of post-complaint behavior. Conducting a meta-analysis, the authors test the following path model: ‘‘organizational responses (compensation, favorable employee behavior, and organizational procedures) → justice perceptions (distributive, interactional, and procedural justice) → post-complaint satisfaction (transaction-specific and cumulative satisfaction) → customer behavioral intentions (loyalty and positive word of mouth [WOM]).’’ The results confirm this model as well as the mediating role of justice perceptions and post-complaint satisfaction. Surprisingly, the results also show that the common contention of distributive justice as the salient driver of service recovery is only true for transaction-specific satisfaction, which in turn reinforces positive WOM. Cumulative satisfaction, however, which is the primary antecedent of customer loyalty, even slightly more depends on interactional justice than on distributive justice. Further, the results show that the relationships between justice perceptions and satisfaction constructs depend on several moderators such as target group, industry, and complaint type. A major managerial implication is the fact that organizations should pay particular attention to distributive justice when complainants are students and to interactional justice when failure is nonmonetary or occurs in service industries. The authors discuss theoretical implications and provide suggestions for future research.
A longitudinal study of two boys’ experiences of acquiring Italian as a second language: the influence of age
Authors: Peçenek Dilek
Published: December 2010

This article presents a description of the acquisition process of Italian as a second language of two Turkish-speaking brothers, in an immersion context. The study intended to capture these boys’ language experiences and language behaviours, and their behavioural-linguistic changes in the second language acquisition process, focusing on age. Other factors such as role of the parents, amount of exposure to the two languages and cross-linguistic influences in relation to these children’s language experiences are also discussed. Longitudinal data for the second language acquisition progress of the boys were collected over four years. The ecological approach was used during the observation and assessment processes of the second language acquisition experiences and performances of the brothers. The information obtained from longitudinal data made it possible to highlight some descriptions, which may serve to explain the process. The children were exposed to the second language under the same conditions and for the same period. By the end of the data collection period some differences in the performance of the brothers’ first and second languages appeared. The elder child maintained his Turkish whereas the younger child displayed difficulties speaking fluently in Turkish and often code-mixed to Italian. The findings of this study indicate that especially age and consequently cognitive development, and also exposure time period, attitude of the parents and linguistic cultural environment might have had significant effects on the boys’ second language acquisition.
Factors Affecting the Functional- and Comfort-related Properties of Reactive Dyed Cotton Knits
Authors: Ibrahim N.A. , Khalifa T.F. , El-Hossamy M.B. , Tawfik T.M.
Published: December 2010

In this study, three different reactive dyed single jersey cotton knits produced from different yarn counts, i.e., Ne 20/1, Ne 24/1, and Ne 30/1 were selected for studying the impact of functional finishes, i.e., soft, bio-antibacterial, and water-repellent, on their performance and comfort-properties. It was found that the variation in the evaluated properties is very much dependent on the yarn count as well as on the type and concentration of the finishing agent. An improvement in pilling levels and tactile properties, i.e., smoothness and softness, as well as in comfort properties, i.e., heat transmittance, air permeability as well as water-absorption, is achieved by the bio-treatment. An enhancement in dimensional stability, pilling levels, bursting strength, tactile properties along with a reasonable improvement in antibacterial efficiency is obtained by soft-finishing, taking in consideration its tendency to entrap heat and air inside the fabric structure. The same holds true for water-repellent treatment, in addition to its outstanding water-repellency the antibacterial finish imparts superior antibacterial activity to the fabrics with marginal or little effect on other properties.

Race, Housing, and Burnham’s Plan: Why is there no Housing in the 1909 Plan of Chicago?
Authors: Garb Margaret
Published: December 2010

This essay contends that the 1909 Plan of Chicago written by Daniel H. Burnham and Edward H. Bennett represented and contributed to a dramatic change in the relationship between public and private spaces in American cities. The plan gave concrete form to the Progressive aim of strengthening government and using the state to shape individual behavior. It reorganized the ideological relationship between the family home and public space, suggesting that the home in the industrializing city was no longer adequate to shape democratic citizens.
Using Mixed Methods to Establish the Social Validity of a Self-Report Assessment: An Illustration Using the Child Occupational Self-Assessment (COSA)
Authors: Kramer Jessica M.
Published: December 2010

Social validity is the extent to which procedures, goals, and outcomes are acceptable and important to end users and is not commonly addressed during assessment development. This article pilots a process of triangulating multiple methods to evaluate the social validity of a self-report assessment. These procedures were piloted using the Child Occupational Self-Assessment (COSA), a self-report of everyday activities for children with disabilities. This study collected COSA responses from 502 children with disabilities and conducted observations and interviews with 5 additional children with cerebral palsy. Data were aligned with social validity benchmark statements and integrated using data displays. Social validity was evaluated by examining congruencies and discrepancies in the results. Implications and the legitimacy of design decisions are discussed.
Pain and paraesthesia produced by silicone ring and pneumatic tourniquets
Authors: Mohan A. , Baskaradas A. , Solan M. , Magnussen P.
Published: December 2010

Twenty volunteers were recruited to compare a novel, silicone ring tourniquet (the Hemaclear® tourniquet) with a pneumatic tourniquet. After application of the tourniquets, the pain and paraesthesia experienced by the participants was scored at 1 minute, 5 minutes, and 10 minutes. This was repeated with the tourniquets on the forearm. On the upper arm, the silicone ring tourniquet was associated with a significantly lower pain score than the pneumatic tourniquet. The incidence of paraesthesia was also lower with the silicone ring tourniquet. When applied to the forearm, there was no statistically significant difference in pain scores between the two types of tourniquets. However the incidence of paraesthesia was again lower with the silicone ring tourniquet.
Seismic petrophysics and isotropic-anisotropic AVO methods for unconventional gas exploration
Authors: Goodway Bill , Perez Marco , Varsek John , Abaco Christian
Published: December 2010

Exploration and drilling for natural gas in North America has moved radically away from conventional reservoirs to focus on unconventional reservoirs such as tight gas sands and shales. These reservoirs have low porosity and near-zero permeability with gas stored in natural fractures and within the matrix porosity. Economic gas production requires hydraulic fracture stimulation to open connections to existing natural fractures or matrix porosity, and successful stimulation depends on the formation's geomechanical brittleness being capable of supporting extensive induced fractures. However, despite adequate stimulation, significant variations exist between wells in expected ultimate recovery (EUR) due to the heterogeneity of these resource plays. Consequently, predicting natural fractures or fracture-prone “sweet spots” is essential to optimize development of such plays.
Revising “Harriet Jacobs” for 1865
Authors: Stewart Anna
Published: December 2010

Stewart examines the narrative construction of Harriet Jacobs in 1865, when her former editor Lydia Maria Child included a revised selection from Incidents in the Life of a Slave Girl (1861) in The Freedmen's Book, a reader Child was developing to help newly freed slaves learn to read and make a life for themselves. Stewart reads the revised selection from Jacobs's narrative as a case study of core tensions in Child's Reconstruction rhetoric and, more broadly, the anxious rhetoric surrounding the postemancipation status of African Americans in 1865. In The Freedmen's Book, Child celebrates a revolutionary tradition with its attendant social disruption at the same time she champions conventional gender roles as a way of patterning much-needed stability in the post-Emancipation United States. Given her involvement in the 1861 publication of Incidents, Child's role in the 1865 narrative raises questions about the slipperiness of textual authority, and Stewart posits that the scholarly debate over Jacobs's authorial legitimacy has perhaps obscured our awareness of her as a textual construction and (Re)construction—a figure whose narrative was ever adapting to a changing political context and the needs of a community in transition.
Speculative Fictions of Slavery
Authors: Dubey Madhu
Published: December 2010

Since the 1970s, African American novelists have persistently drawn on antirealist genres (including science fiction, fantasy, ghost stories, and magic realism) to revisit the history of slavery. Focusing on literary and mass-market fiction by authors such as Stephen Barnes, David Bradley, Octavia Butler, James McBride, and Phyllis Alesia Perry, Dubey explores the various ways the generic choice of speculative fiction sponsors a purposefully antihistorical approach to the past. Speculative novels of slavery employ paranormal narrative devices of time-travel and supernatural possession in order to foster an immediate and experiential, affective and embodied knowledge of slavery. Revealing the haunting afterlife of the past in the present, the time-bending mechanisms that are distinctive of the genre of speculative fiction narrate the past of slavery as something other or more than history. Through their refusal to grasp slavery as an occurrence that has decisively passed into the register of history, these novels dispute the meta-narrative of U.S. racial history—as a progressive movement launched with the abolition of slavery and culminating in the Civil Rights movement—that began to gain momentum in the 1970s. Dubey argues that the suspicion of history found in speculative fictions of slavery bespeaks a strong sense of uncertainty and pessimism about future prospects for racial politics in post–Civil Rights decades.

Assessing What Distinguishes Highly Cited from Less-Cited Papers Published in Interfaces
Authors: Hamrick Thomas A. , Fricker Ronald D. , Brown Gerald G.
Published: December 2010

We evaluate what distinguishes a highly cited Interfaces paper from other Interfaces papers that are cited less often. Citations are used to acknowledge prior relevant research, to document sources of information, and to substantiate claims. As such, citations play a key role in the evolution of knowledge. More recently, citations are also being used to quantify the impact of papers and journals, a practice not without controversy, but one that motivates our work here. We find that Edelman competition papers, longer papers, tutorials, papers with larger numbers of references to prior literature, and papers with a larger number of “callouts” (a feature no longer used by Interfaces) tend to have a higher number of citations.
The contribution of different types of knowledge towards understanding, sharing and communication risk concepts
Authors: Renn Ortwin
Published: December 2010

Risks represent threats to what humans value. The link between risk as a mental concept and reality is forged through the experience of actual harm (the consequence of risk). The invention of risk as a mental construct is contingent upon the belief that human action can prevent or at least mitigate harm. Based on this implicit normative goal it is important to collect the best available knowledge about the sequences that could lead to harm. The major claim of this article is that, in addition to systematic modelling of causes and potential effects revealed by scientific investigations, experiential, tacit and intuitive knowledge can contribute to a better understanding as well as management of risk. Providing platforms for communication between and among the carriers of these four knowledge types, and structuring a mutual learning process should be a major target in the design of risk communication programmes.
Communicating at the edge: Risk communication processes and structural conflicts in highly industrialized petrochemical areas
Authors: Espluga Josep , Prades Ana , Gonzalo Jan
Published: December 2010

This article, grounded in an empirical study carried out in the Tarragona petrochemical complex (Spain), explores how key actors operating in this specific social and organizational context perceive petrochemical communication activities. Data compiled from a set of interviews with
stakeholders and focus group discussions with citizens were analysed from an interpretative perspective in an effort to capture underlying situationally specific logics. The results enabled us to discuss the advantages and limitations of different theoretical models of petrochemical communication,
providing elements for a critique of overly simplistic normative models of risk communication. We highlight the potential contribution of interpretative research to the social perception of petrochemical risk and its implication in petrochemical communication processes.
Nicole, Papa, Blackpool Tower, the Eiffel Tower and Thierry Henry

The article is concerned with the deployment of European (especially French) characters and motifs in British screen advertising from the 1970s to the present and the means whereby particular products (cars, cosmetics, drinks) are designated as French. It is especially concerned with
the appropriation of French films in ads, through direct pillaging of found footage and through imitation, and the gestural use of French films to designate, more generally, shifting perceptions of the foreignness and difference of Europe. Advertising, it is acknowledged, also has its own
trends and cycles, pursued regardless of external factors, within brands and amongst agencies. Screen advertising (Stella and VW) increasingly permeates the production, distribution and exhibition of cinema in Britain.
Hidden: Jewish Film in the United Kingdom, past and present
Authors: Abrams Nathan
Published: December 2010

Abrams provides a preliminary survey of the representation of Jews in British cinema both in front of and behind the camera from the beginnings of the UK film industry to the present day. In doing so, he outlines the reason for the relative lack of films in Britain that can be considered
Jewish. While there are a variety of factors for this, the main reason he argues is the type of identity that British Jews have developed as a response to their context. However, since 1990 there have been signs that this is beginning to change, and more films reflective of the British-Jewish
experience are appearing.

Combining Gray Relation and Analytical Hierarchy Process Concepts to Develop a Decision Support System of Supply Chain Project Management
Authors: Lin Chin-Tsai , Wu Cheng-Ru , Chen Huang-Chu
Published: December 2010

Supplier selection is an important decision for effective supply chain project management (SCPM) of Notebook PC. Due to global business competition, suppliers are required to supply raw materials with the right quality and quantity. Suppliers are responsible for reducing the inventory costs and improving product quality. This paper deals with the development of a decision support system based on the integration of analytical hierarchy process and gray relational analysis for supplier selection. The additive normalization method is used as the prioritization method to calculate the priority vector. The analysis results indicate that the proposed selection model enables the manager to select the SCPM of Notebook PC more objectively by allowing them to deploy effectively. The proposed model can also be applied to other high technology factories, thus enhancing Taiwanese competitive advantage.
Research with Aboriginal Peoples: Authentic Relationships as a Precursor to Ethical Research
Authors: Bull Julie R.
Published: December 2010

Recent ethics guidelines and policies are changing the way health research is understood, governed, and practiced among Aboriginal communities in Canada. This provides a unique opportunity to examine the meanings and uses of such guidelines by Aboriginal communities themselves. This qualitative study, conducted in Labrador, Canada, with the Innu, Inuit, and Inuit-Metis, examined how communities and researchers collaborate in a co-learning environment whereby mutual interests and agendas are discussed and enacted throughout the entire research process—a process referred to an authentic research relationship. The purpose of this study was to answer the following questions: (1) Why are authentic research relationships important? (2) What is authenticity in research? (3) How do we achieve authenticity in research with Aboriginal peoples? This shift to more wholistic methodologies can be used in various contexts in Canada and internationally. This is the first study by an Aboriginal person to examine the perspectives of Aboriginal people, in an Aboriginal context, using Aboriginal methodologies.
Faculty Beliefs, Perceptions, and Level of Community Involvement in Their Research: A Survey at One Urban Academic Institution
Authors: Goldberg-Freeman Clara , Kass Nancy , Gielen Andrea , Tracey Patricia , Bates-Hopkins Barbara , Farfel Mark
Published: December 2010

Health researchers are increasingly interested in how best to engage communities in their health-related research studies. To help determine how researchers have interacted with community members in their research, we conducted a survey of full-time faculty from the Johns Hopkins Medical Institutions regarding researchers' beliefs and experiences with community-based research. Approximately 41% of respondents who conducted human subject studies had enrolled local residents in their research. Researchers whose studies were based in the surrounding community were significantly more likely to involve community members in all stages of their research (e.g., selection of the problem, project planning, data collection, interpretation and dissemination of results, or developing an intervention) than were faculty whose studies enrolled community members as research participants but whose studies were not set in the community. Over 90% of all faculty respondents agree that community involvement improves the relevance of their research, although almost 60% had not done so. Most faculty value community involvement, but they want more institutional support for such activities and they seek better skills to involve community. Few studies have surveyed researchers who enroll community members as research participants to document practices regarding community involvement in the research process. Given that the majority (73.6%) of faculty responded that they intend to include local residents in their upcoming studies, future research to evaluate interventions designed to facilitate community involvement, especially in the inner city, would help stakeholders identify best practices for involving and engaging communities in health research.

Deposition of Evaporating Droplets in a Decelerating Boundary Layer with Wall Suction: Mathematical Analysis
Authors: Orland Ro'ee Z , Tadmor Rafael , Katoshevski David
Published: December 2010

The problem of spray/droplets dynamics in a downstream decelerating boundary layer accompanied by evaporation and wall suction is treated analytically. A similarity approach is employed and explicit expressions are obtained for the distribution of the host-gas velocity and for the distribution of the liquid phase. Several options are considered in terms of evaporation, including the possibilities of constant evaporation in the lateral direction of the boundary layer and of evaporation dependent on proximity to the wall. The results reveal the possibility that, under certain conditions, the liquid phase concentration reaches an extremum inside the boundary layer domain, rather than at the wall or in the free stream.

Published: December 2010

Listeria spp. are Gram positive, short, non-sporing rods, microaerophilic. Of
the six species currently recognized, Listeria monocytogenes is the most
important as it causes a range of infections in humans and animals. The
organism can be found in a wide variety of habitats including the soil, food
processing environments and raw foods. The ability of the organism to grow at
refrigeration temperatures is of major importance in food production. This
study examines the presence of Listeria species in fresh meat. 29 samples
(chicken, pork and beef) meat. This bacteria was found in 82.7% of analyzed
samples; 7 L. innocua, 8 L. monocytogenes and 9 L. welshimeri (of all
isolates). L. innocua prevailed in pork meat (40%), L. monocytogenes in
chicken and pork meat (30%), and L. welshimeri in beef meat (44.4%).
Physicochemical, biochemical and sensory properties for the characterization of Petrovská klobása (traditional fermented sausage)

Published: December 2010

A study was carried out on a typical homemade Petrovsk? klobas? in order to
characterize this traditional dry-fermented sausage, to provide a basis for
establishing the quality standard and protecting designation of origin. This
paper reviews the chemical composition, some physicochemical, proteolytic and
sensory parameters of Petrovsk? klobas? made by five manufacturers chosen as
representatives. Beside the differences between sausages made by different
manufacturers the main properties of this traditional product were though
recognized. Compared to other dry-fermented sausages Petrovsk? klobas? is
characterized by a high content of protein (23.36-30.45%) and low contents of
NaCl (2.99-3.28%). With some minor exceptions, the values of other chemical
parameters are within the range of those observed for various dry-cured
sausages. Weight loss during the processing is high (up to 45.71%) and pH
value (~ 5.4) corresponds to the values for this parameter in other European
traditional fermented sausages. Contents of different nitrogen fractions show
that Petrovsk? klobas? undergoes significant proteolytic changes. At the end
of ripening, Petrovsk? klobas? is characterized by aromatic and spicy-hot
flavor, dark-red color and hard consistency.
Protein composition in tofu of corrected quality
Authors: Stanojevic Sladjana , Barac Miroljub , Pesic Mirjana , Milovanovic Mirjana , Vucelic-Radovic Biljana
Published: December 2010

Soybeans are an inexpensive, high-quality protein source. Soybeans have long
been a staple of the human diet in Asia, especially as tofu, which is
prepared from soymilk. In this study, tofu was made using a new production
method which includes hydrothermal cooking (HTC) and rennin-pepsin coagulant.
The effects of the addition of gallic acid to the slurry during tofu
processing were studied. Tofu was made from two soybean genotypes: Lana and
Balkan. The observed genotypes are characterized by relatively high content
of total proteins in flour, from 45.88% to 48.83%. The prepared tofu samples
are characterized by extremely high content of total proteins (52.17% - Lana
tofu and 56.08% - Balkan tofu). The presence of gallic acid significantly
affects the solubility of tofu protein. The applied modifications of
traditional procedure of tofu production significantly improved sensory
properties of soybean protein products.
Critical review of supercritical carbon dioxide extraction of selected oil seeds
Authors: Sovilj Milan
Published: December 2010

Supercritical carbon dioxide extraction, as a relatively new separation
technique, can be used as a very efficient process in the production of
essential oils and oleoresins from many of plant materials. The extracts from
these materials are a good basis for the new pharmaceutical products and
ingredients in the functional foods. This paper deals with supercritical
carbon dioxide extraction of selected oil seeds which are of little interest
in classical extraction in the food industry. In this article the process
parameters in the supercritical carbon dioxide extraction, such as pressure,
temperature, solvent flow rate, diameter of gound materials, and moisture of
oil seed were presented for the following seeds: almond fruits, borage seed,
corn germ, grape seed, evening primrose, hazelnut, linseed, pumpkin seed,
walnut, and wheat germ. The values of investigated parameters in
supercritical extraction were: pressure from 100 to 600 bar, temperature from
10 to 70oC, diameter of grinding material from 0.16 to 2.0 mm, solvent flow
used from 0.06 to 30.0 kg/h, amount of oil in the feed from 10.0 to 74.0%,
and moisture of oil seed from 1.1 to 7.5%. The yield and quality of the
extracts of all the oil seeds as well as the possibility of their application
in the pharmaceutical and food, industries were analyzed.
Mg-Cu-Al layered double hydroxides based catalysts for the reduction of nitrates in aqueous solutions
Authors: Vulic Tatjana , Boskovic Goran
Published: December 2010

The secondary waste and bacterial contamination in physico-chemical and
biological separation processes used today for nitrate removal from ground
water make novel catalytic technologies that convert nitrates to unharmful
gaseous nitrogen, very attractive for scientific research. The Mg-Cu-Al
layered double hydroxide (LDH) based catalysts with different Mg/Al ratio
were investigated in water denitrification reaction in the presence of
hydrogen and with solely copper as an active phase. Since LDHs have ion
exchange properties and their derived mixed oxides possess memory effect
(restoration of layered structure after thermal decomposition), their
adsorption capacity for nitrates was also measured in the same model system.
All studied samples showed nitrate removal from 23% to 62% following the
decrease in Al content, as well as the substantial adsorption capacity
ranging from 18% to 38%. These results underlie the necessity to take into
account the effects of the adsorption in all future investigations.
Correlation between the lipophilicity and antifungal activity of some benzoxazole derivatives
Authors: Podunavac-Kuzmanovic Sanja , Velimirovic Sonja
Published: December 2010

In the present work, a quantitative relationship between the lipophilicity
and antifungal activity of some benzoxazole derivatives against Candida
albicans was investigated by using QSAR (quantitative structure-activity
relationship) analyses. The descriptors which describe numerically the
lipophilicity, logP, were calculated using Chem-Office Software version 7.0.
The linear correlation between the minimal inhibitory concentration
(log1/cMIC) and lipophilicity descriptors was investigated. The best QSAR
model predicting the antifungal activity of the investigated series of
benzoxazole was developed. The results are discussed on the basis of
statistical data. High agreement between theoretical and experimental
inhibitory values was obtained. The results of this study indicate that the
lipophilicity parameter has a significant effect on antifungal activity of
this class of compounds, which can be very useful in the design of new
biologically active molecules.

Published: December 2010

The influence of biostimulant and substrate volume on scarlet sage
transplants growth and development was examined in this investigation. There
was one cultivar of scarlet sage used in trial which was transplanted in pots
of two different volumes. Plants were treated with biostimulant (Radifarm) in
concentration of 0.25% or left untreated (control). During the trial, root
and aboveground fresh and dry mass were recorded. Treatment with biostimulant
and bigger substrate volume showed good results by increasing investigated
parameters. Investigation shows how biostimulant application to scarlet sage
transplants production improves growth and development of root and
aboveground mass which is important for faster plant adaptation to stress
during transplanting.

squared mean curvature and the normalized scalar normal curvature) holds on
any 3-dimensional submanifold M3 with arbitrary codimension m in any real
space form ~M3+m(k) of curvature k. For a given Riemannian manifold M3, this
inequality can be interpreted as follows: for all possible isometric
immersions of M3 in space forms ~M3+m(k), the value of the intrinsic
curvature ? of M puts a lower bound to all possible values of the extrinsic
curvature H2 ? ?? + k that M in any case can not avoid to ?undergo" as a
submanifold of ?M. From this point of view, M is called a Wintgen ideal
submanifold of ~M when this extrinsic curvature H2 ??? +k actually assumes
its theoretically smallest possible value, as given by its intrinsic
curvature ?, at all points of M. We show that the pseudo-symmetry or,
equivalently, the property to be quasi-Einstein of such 3-dimensional
Wintgen ideal submanifolds M3 of M~3+m(k) can be characterized in terms of
the intrinsic minimal values of the Ricci curvatures and of the Riemannian
sectional curvatures of M and of the extrinsic notions of the umbilicity,
the minimality and the pseudo-umbilicity of M in ~M.
Efficient greyscale image compression technique based on vector quantization
Authors: Hu Y. , Chuang J. , Lo C. , Li C.
Published: December 2010

In this paper, a novel greyscale image coding technique based on vector quantization (VQ) is proposed. In VQ, the reconstructed image quality is restricted by the codebook used in the image encoding/decoding procedures. To provide a better image quality using a fixed-sized codebook, the codebook expansion technique is introduced in the proposed technique. In addition, the block prediction technique and the relatively address technique are employed to cut down the required storage cost of the compressed codes. From the results, it is shown that the proposed technique adaptively provides better image quality at low bit rates than VQ.

Published: December 2010

The liquid crystal technology is one of the most popular at the present time. To the most important parameters of liquid crystals belong optical anisotropy, viscosity, and twist elastic constants. One of the most difficult and problematic to measure parameters is a twist elastic constant K22. For new liquid crystalline materials, we have to characterize their physical properties, also a twist elastic constant K22.

As a final result of this work, a twist elastic constant of new nematic liquid crystal materials was investigated. In this paper, a transmission-voltage characteristic of the in-plane switching cell was observed to find Freedericksz threshold, and then twist elastic constants could have been calculated. The method was checked on well-characterized materials E7 and 6-CHBT and its accuracy was better than 20%. In addition, the temperature dependence of K22 was determined for all materials.
Oceanic Dimethyl Sulfide Emission and New Particle Formation around the Coast of Antarctica: A Modeling Study of Seasonal Variations and Comparison with Measurements
Authors: Yu Fangqun , Luo Gan
Published: December 2010

A clear understanding of new particle formation processes in remote oceans is critical for properly assessing the role of oceanic dimethyl sulfide (DMS) emission on the Earth’s climate and associated climate feedback processes. Almost free from anthropogenic pollutants and leafed plants, the Antarctic continent and surrounding oceans are unique regions for studying the lifecycle of natural sulfate aerosols. Here we investigate the well-recognized seasonal variations of new particle formation around Antarctic coastal areas with a recently developed global size-resolved aerosol model. Our simulations indicate that enhanced DMS emission and photochemistry during the austral summer season lead to significant new particle formation via ion-mediated nucleation (IMN) and much higher particle number concentrations over Antarctica and surrounding oceans. By comparing predicted condensation nuclei larger than 10 nm (CN10) during a three-year period (2005–2007) with the long-period continuous CN10 measurements at the German Antarctic station Neumayer, we show that the model captures the absolute values of monthly mean CN10 (within a factor 2–3) as well as their seasonal variations. Our simulations confirm that the observed Antarctic CN10 and cloud condensation nuclei (CCN) seasonal variations are due to the formation of secondary particles during the austral summer. From the austral winter to summer, the zonally averaged CN10 and CCN in the lower troposphere over Antarctica increase by a factor of ~4–6 and ~2–4, respectively. This study appears to show that the H2SO4-H2O IMN mechanism is able to account for the new particle formation frequently observed in the Antarctica region during the austral summer.

Scaling up Semi-Arid Grassland Biochemical Content from the Leaf to the Canopy Level: Challenges and Opportunities
Authors: He Yuhong , Mui Amy
Published: December 2010

Remote sensing imagery is being used intensively to estimate the biochemical content of vegetation (e.g., chlorophyll, nitrogen, and lignin) at the leaf level. As a result of our need for vegetation biochemical information and our increasing ability to obtain canopy spectral data, a few techniques have been explored to scale leaf-level biochemical content to the canopy level for forests and crops. However, due to the contribution of non-green materials (i.e., standing dead litter, rock, and bare soil) from canopy spectra in semi-arid grasslands, it is difficult to obtain information about grassland biochemical content from remote sensing data at the canopy level. This paper summarizes available methods used to scale biochemical information from the leaf level to the canopy level and groups these methods into three categories: direct extrapolation, canopy-integrated approach, and inversion of physical models. As for semi-arid heterogeneous grasslands, we conclude that all methods are useful, but none are ideal. It is recommended that future research should explore a systematic upscaling framework which combines spatial pattern analysis, canopy-integrated approach, and modeling methods to retrieve vegetation biochemical content at the canopy level.
Low-Cost Electronic Microwave Calibration for Rapid On-Line Moisture Sensing of Seedcotton
Authors: Pelletier Mathew G. , Viera Joseph A.
Published: December 2010

In order to improve rapid on-line moisture sensing of seedcotton in cotton gins, a means by which to establish a reliable low-cost wide-band electronic calibration is critically needed. This calibration is needed to center the circuit due to changes in the internal signal delays and attenuation drift caused by temperature changes in the various system components and circuit elements. This research examines a hardware technique for use in conjunction with microwave reflective sensing probes having an extended bandwidth from 500 MHz through 2.5 GHz. This new technique was validated experimentally against known electrical propagation delay standards. Results of the measured propagation delay with this type of automatic electronic calibration method was found to agree with results using a vector network analyzer with a traditional S11 single port error correction calibration methodology to within 4% of the measurement, 95% confidence, with a standard error of +/−18.6 ps for the delay measurements. At this level of performance, the proposed low-cost technique exhibits superior performance, over the typical geosciences time-domain reflectometer “TDR”, instruments in common use in soil moisture testing and is suitable for use in cotton gin moisture sensing.
Des raisons d’utiliser les images pour informer sur la réalité et de la difficulté de ne pas confondre le document et le monde
Authors: Tisseron Serge
Published: December 2010

Nous avons besoin à la fois de mots et d’images pour penser. Mais dans les deux cas nous courons deux risques: l’emballement émotionnel et la réduction de la complexité du monde au point de vue du discours. Tout document, qu’il soit écrit ou filmé, rencontre ces deux difficultés. Mais les images contiennent encore un autre danger: confondre leur impact sur nous, étroitement tributaire de nos représentations personnelles, avec ce qu’elles contiennent en réalité.
La mise en scène de la parole dans le cinéma ethnographique
Authors: Arlaud Jean
Published: December 2010

Les perfectionnements technologiques d’enregistrement de l’image et du son ont donné au statut de la parole une place de plus en plus prépondérante dans le cinéma ethnologique et sociologique. Le commentaire a progressivement cédé la place à l’expression directe des sujets filmés dans l’interprétation de leur propre univers. Mais l’émergence de cette parole ne peut se faire que dans le cadre précis d’un dispositif de mise en scène du réel instauré, selon sa problématique, par le réalisateur lui-même.
