Fantasizing Violence
Authors: Linke Uli
Published: December 2010

Anti–Establishment activists and members of the Green/Alternative party in Berlin (Germany) tend to promote the use of fantasized violence as a medium for political contestation. A range of highly charged image schemata, focused on death, silencing, and physical brutality (typified by the swastika, SS sign, gallows, Nazi rhetoric, death camps) are appropriated as anti–symbols, transformed into a “language” of resistance against the German state. Fantasies of violence, directed against the political other are thereby not merely historicized, but reproduced as templates for action and identity. Based on fieldwork in Berlin (1988–89, 1991, 1994), this paper explores the cognitive aspects of such fantasizing, and analyzes the resulting political process, with its paradoxes of legitimacy and contestation.

Finding Meaning in the Muddle: Adapting Global Strategies to Advertising in Japan
Authors: Mccreery John
Published: December 2010

When a Japanese advertising agency develops campaigns for multinational clients, cultures clash. Conflict, confusion and misunderstanding complicate the already complex processes involved in the production of advertising. Can anthropological theory illuminate what is going on? The answer is “Yes.” Concepts of field, habitus and social drama developed by Pierre Bourdieu and Victor Turner do shed light on this highly fraught cross‐cultural encounter. Only one critical element is missing: effective leadership. [Advertising, Japan, leadership, globalization, applied anthropology]

Increasing Research Literacy in Minority Communities: CARES Fellows Training Program
Authors: Goodman Melody S. , Dias Janice Johnson , Stafford Jewel D.
Published: December 2010

The community alliance for Research Empowering Social Change (CARES) is an academic-community research partnership designed to: (1) train community members about evidence-based public health, (2) increase community members' scientific literacy, and (3) develop the infrastructure for community-based participatory research so that local stakeholders can examine and address racial/ethnic health disparities in their communities. Nineteen community members enrolled in the CARES training. The training consisted of 11 didactic training sessions and 4 experiential workshops, taught by a multidisciplinary faculty from research institutions. Results suggest that the training increased research literacy, prepared community members for collaborative work with academic researchers, and empowered them to utilize scientific research methods to create social change in their communities.
Community-Based Participatory Research in Disaster Preparedness Among Linguistically Isolated Populations: A Public Health Perspective
Authors: Nepal Vishnu , Banerjee Deborah , Slentz Monica , Perry Mark , Scott Deborah
Published: December 2010

Working with linguistically isolated immigrants on public health issues poses a set of methodological challenges unique to this population. We used community-based participatory research (CBPR) techniques to investigate the disaster preparedness needs of four linguistically isolated population groups in Houston, Texas (Vietnamese, Chinese, Somali, and Spanish–speaking) in partnership with community-based organizations and community researchers. As a local health department conducting CBPR, we witnessed various challenges, including: Engaging and using interpreters versus using community researchers; translating focus group questions from English to other languages; recruiting participants from linguistically isolated populations; and handling issues of community power, data collection, and data reliability. In this article, we discuss these challenges, strategies used, and the outcomes of our approaches in the broader context of CBPR.

Bone Microbial Decontamination Agents in Osseous Grafting: An In Vitro Study With Fresh Human Explants
Authors: Verdugo Fernando , Sáez‐Rosón Aranzazu , Uribarri Agurne , Martínez‐Conde Rafael , Cabezas‐Olcoz Jonathan , Moragues María D. , Pontón José
Published: December 2010

Background: Establishing a safe prophylactic antimicrobial protocol in bone grafting may enhance osseous volume outcomes. The purpose of this in vitro study is to assess human osteoblast response and safety after explant antimicrobial exposure.

Methods: Fresh human bone explants were exposed to three antimicrobials: povidone‐iodine (PovI; 0.05%, 1%, and 5%), chlorhexidine (CHX; 0.2% and 1%), and sodium hypochlorite (NaOCl; 2.5%, 4.5%, and 5.25%) at different times (15, 30, 45, and 60 seconds) and concentrations to assess cellular toxicity. Explants were washed three times with saline after exposure. Controls, explants cultured in the absence of antimicrobials, were performed for all experimental situations tested. Trials were conducted in triplicate. Particle size influence on osteoblast growth was determined between bone fragments with a diameter <2 and ≥2 to 5 mm. Test and control groups were monitored by light microscopy to evaluate cellular growth. Osteoblast differentiation and morphology was assessed by alkaline phosphatase activity and scanning electron microscopy (SEM).

Results: Osteoblast growth was similar for particles <2 and ≥2 to 5 mm. Alkaline phosphatase control reference values were not significantly different from test groups (0.35 mU/mL ± 0.004 versus 0.34 mU/mL ± 0.009; P >0.05). Light microscopy showed on average 97% osteoblastic growth for bone particles exposed to PovI 5% and CHX 0.2% for all times and CHX 1% up to 30 seconds. The odds ratio of positive osteoblastic growth after a 30‐second 2.5% NaOCl exposure was 2.4 times higher than after 5.25%. On average, one of two replicas yielded positive growth with 2.5% NaOCl and one of three with 5.25%. After 60‐second explant exposure, positive osteoblastic growth was 7.7 times more likely to occur with 5% PovI or 0.2% CHX than with 5.25% NaOCl (P <0.05). SEM analysis confirmed light microscopy similar cellular adhesion and osteoblast phenotypic features between test and control groups.

Conclusions: Best osteoblastic growth occurred after bone PovI exposure and CHX 0.2%. Cellular toxicity seems to be influenced by the type of antimicrobial, concentration, and exposure time. SEM analysis confirmed absence of osteoblast phenotypic alterations after exposure. Decontamination agents can safely be used in bone transplantation using up to 5% PovI and 0.2% CHX for 1 minute and CHX 1% for 30 seconds.

Authors: Chakraborty Subir Kumar , Kumbhar B.K. , Chakraborty Shalini , Yadav Pravesh , Sharma Harsh Prakash
Published: December 2010

The effects of baking time and baking temperature on colour (L*a*b*), colour difference (?E) and overall acceptability (OAA) of biscuits made from different blends of refined wheat flour (RWF) and millet was investigated using a three factor central composite rotatable design (CCRD). ANOVA for response surface model demonstrated that the data could fit the three polynomial models adequately. All the models were found to be statistically sound to predict the responses. The colour values and OAA were significantly influenced by the processing variables at different levels of significance. The blend ratio, percent RWF, was found to have an overwhelming effect on all the colour values and OAA. It was predicted that the optimum product colour characteristics in terms of L*(29.45), a*(-105.01), b*(-92.7), ?E (11.9) and OAA (6.3) were obtained at blend ratio, 70 percent RWF; baking time, 5.6 min; and baking temperature, 171.7°C.
The Effect of Misspecifying Latent and Infectious Periods in Space-Time Epidemic Models
Authors: Habibzadeh Babak , Deardon Rob
Published: December 2010

Individual level models (ILMs) are a class of models that can be applied to epidemic data to help in the understanding of the spatio-temporal dynamics of infectious diseases. Typically, these models are analyzed in a Bayesian framework using Markov chain Monte Carlo (MCMC) methodology. Here, we test the effect of misspecifying the latent and infectious period in such a model. We do this by simulating data from a simple spatial ILM, and then fitting various misspecified models to the simulated data. The fitted models serve as a basis for investigating the effect of the misspecification of latent and infectious periods on model parameter estimates, as well as estimates of the basic reproduction number.Additionally, we analyze how a given preventative control strategy, optimized via simulation from a fitted model with assumed latent and infectious periods, is affected by such misspecification. We observe bias in the estimation of model parameters as latent and infectious periods become more misspecified, as well as a significant deviation in estimates of the basic reproduction number from those observed under the true model. Where the misspecification results in a higher basic reproduction number estimate, we also find that a more stringent control policy is required to achieve a given policy goal.

Published: December 2010

We compare term by term the paperfolding sequence with a copy displaced by d
terms to obtain the matching fraction M (d). It is shown that M(d) has an
interesting structure in that if d=2b(1+2s), then M(d)=
|1-3/2b+1| thereby generating horizontal bands for each value of b. That
is, M(d) depends only on b.
The application of triticale variety Odyssey as the substitute for malt in wort production
Authors: Grujic Olgica , Pejin Jelena , Dencic Srbislav
Published: December 2010

The objective of this work was to investigate the possibility of triticale
application as the partial substitute for malt in wort production. For wort
production, two series of experiments were performed in which triticale
variety Odyssey, from experimental fields, Rimski Sancevi location (Serbia),
was used as the substitute for barley malt in grist with and without the
addition of commercial enzyme Ultraflo Max (Novozymes, Denmark). Triticale
was added in each of the carried series of experiments as the substitute for
malt: 0, 10, 20, 30, 40, 50, 60, 70 and 80% in grist. Experiments were
carried out on laboratory scale by the application of infusion procedure for
wort production. Regarding extract content, triticale variety Odyssey could
be used as the substitute for malt up to 60% without the addition of
commercial enzyme Ultraflo Max. With the addition of this enzyme triticale
variety Odyssey could be used as a substitute for malt up to 80%, regarding
the extract content. With the increase in the content of triticale in the
grist, viscosity increased. The addition of commercial enzyme Ultraflo Max
significantly reduced wort viscosity. The obtained results indicate that
worts produced with the addition of triticale variety Odyssey to grist
yielded good analytical quality parameters.

Authors: Koprivica Gordana , Misljenovic Nevena , Levic Ljubinko , Jevric Lidija , Filipcev Bojana
Published: December 2010

The osmotic dehydration process of carrot in sugar beet molasses solutions
(40, 60 and 80%), at three temperatures (45, 55 and 65?C) and atmospheric
pressure, was studied. The main aim was to investigate the effects of
immersion time, working temperature and molasses concentration on mass
transfer kinetics during osmotic dehydration. The most important kinetic
parameters were determined after 20, 40, 60, 90, 120, 180, 240 and 300 min of
dehydration. Diffusion of water and solute was the most intensive during the
first hour of the process and the maximal effect was observed during the
first 3 hours of immersion. During the next two hours of dehydration, the
process stagnated, which implied that the dehydration time can be limited to
3 hours.

Published: December 2010

Mandarin peel, a waste product coming from juice production, was extracted by
conventional extraction with 70% acetone. Content of flavonoids in mandarin
peel extract (MPE) was determined by HPLC. Hesperidin was the most dominant
flavonoid. Free radical scavenging activity of MPE on stable DPPH radicals
and reactive hydroxyl radicals was also evaluated. EC50 value determined in
spectrophotometrical DPPH radical assay was 0.179 mg/ml, while this value in
ESR spin trapping hydroxyl radical assay was 0.415 mg/ml. Also, MPE showed
protective effects in stabilising sunflower oil during accelerated storage.
The results indicated that mandarin peel can be a valuable source of natural
antioxidants.
The influence of surface finishing of Paulownia Siebold et Zucc. on the mechanical properties of lacquered surface
Authors: Jaic Milan , Dobic Jovan , Palija Tanja
Published: December 2010

This paper presents the research of influence of sanding, staining and the
use of polyurethane and acrylic coating on the adhesion, scratch resistance
and abrasion resistance of the coating. Objective was to determine the most
important mechanical properties of lacquered surfaces, considering the
application of Paulownia elongata and Paulownia fortunei, by using different
systems of surface finishing. Cross cut method was used for measurement of
adhesion. More accurate view of coating adhesion was obtained by measuring
the scratch resistance. Abrasion resistance was tested by the method of free
falling of abrasive particles. The applied system of sanding had no effect on
the examined mechanical properties. Stained samples lacquered with PU coating
showed better adhesion to the non-stained samples. Impact of staining on
scratch resistance is not established. Stained samples showed greater
resistance to abrasion for both wood species. Samples lacquered with PU
coating showed the higher values of mechanical properties compared with
samples lacquered with UV acrylic coating. Application of PU coating for
surface finishing of Paulownia elongata and Paulownia fortunei is more
adequate than the application of UV acrylic coatings, from the point of
scratch resistance and abrasion resistance.
Floristic diversity of beech, fir and spruce forest (Piceo-Fago-Abietetum Colic 1965) in the „Tara“ national park
Authors: Cvjeticanin Rade , Novakovic Marijana
Published: December 2010

This paper deals with the forest plant community of beech, fir and spruce
(Piceo-Fago-Abietetum Colic 1965), which is the most widely distributed plant
community on the territory of national park ?Tara?. Spectrum of life forms
and floristic elements are specified for this community. Spectrum of life
forms shows that hemicryptophytes are the most frequent, with high occurrence
of geophytes, which is characteristic of this mesophilous plant community.
Spectrum of floristic elements show that centraleuropean floristic element is
dominant and that this plant community is under strong influence of
subcentraleuropean region. Five subassociations are set apart on the basis of
floristic composition and site conditions: typicum, drymetosum, aceretosum,
pinetosum silvestrae and vaccinietosum. Spectrum of life forms is made for
every subassociation separately in aim to compare their floristic
compositions. Subassociations aceretosum and vaccinietosum are characterized
by the highest occurence of phanerophytes, and the lowest occurence of this
life form is represented in subassociation drymetosum. The highest occurence
of geophytes is in subassociation aceretosum, and the lowest in pinetosum
silvestrae and vaccinietosum. Occurence of hemicryptophytes is the highest in
subassociations drymetosum and pinetosum silvestrae, and the lowest in
aceretosum. Subassociation typicum is stable plant community, subassociations
drymetosum and vaccinietosum grow on poorer sites, while subassociations
aceretosum and pinetosum silvestrae represent degradation of beech, fir and
spruce forest (Piceo-Fago-Abietetum Colic 1965).

Published: December 2010

Tobacco (Nicotiana tabacum L.) belongs to the group of plants that produce
agricultural raw material. Besides leaves, which are used to satisfy the
passion for smoking, tobacco can be used for producing oil and biodiesel,
because it contains 30-40% of vegetable oil. Because of its content of citric
acid, tobacco can be used for production of dyes and varnishes. Seed cake
contains high percentage of proteins (35-44%) and can be used as livestock
feed. Because of the high contents of lignin (40-45%) and cellulose (28-40%),
tobacco stems can be used for production of energy briquettes, which makes
tobacco obtain a new usability value. The aim of the experimental researches
presented in this paper is to define the possibilities for production of
briquettes from tobacco stems and wood raw material and to evaluate the
impact of this kind of raw material on briquettes properties. For this
purpose five models were made: O-control model: 100% wood raw material (BW);
model T-I - 25% tobacco stems (TS) : 75% BW; model T-II - 50% TS : 50% BW;
model T-III - 75% TS : 25% BW and model T-IV - 100% TS. The results of the
research show that density of the briquettes is within the limits of 526.61
kg/m3 for model T-IV, to 782.73 kg/m3 for control model-O. The ash content is
a little lower than the standard values and it ranges from 0.32% for
O-control model, to 2.17% for model T-IV. The sulphur content is much below
permissible content (0.08%), and it ranges from 0.003 to 0.008%. These
briquettes, according to the low calorific value are classified in II and I
class. In the smoke of the burned briquettes, minimal quantity (0.005%) of
nicotine is identified.
Effects of heat processing on soya bean fatty acids content and the lipoxygenase activity

Published: December 2010

Effects of increased temperatures on the lipoxygenase activity and changes of
soya bean fatty acids were observed in the present study. The kernels of soya
bean cultivars Bosa and ZPS 015 were subjected to the treatments of
extrusion, autoclaving, micronisation and microwave roasting. Depending on
the technological processing procedure, the kernels were exposed to
temperatures ranging from 60 to 150?C for 25 to 30 seconds during extrusion
and for 30 minutes during autoclaving. The temperature that developed in the
course of the microwave radiation and autoclaving did not cause statistically
significant differences between oil content in heat treated and fresh kernels
of soya bean. However, the oil content was higher in soya bean flakes
(micronized kernels) and lower in grits than in fresh kernels. The heat
treatments resulted in the significant decrease of the linolenic fatty acid
content. Depending on the temperature and applied heat treatments, the
content of linoleic and oleic fatty acid oscillated. High temperatures caused
changes in unsaturated fatty acids with 18 carbon atoms resulting in relative
increase of the stearic acid content. The lipoxygenase activity decreased in
correlation with increased temperatures and the time of heating. The maximum
drop of the activity was observed after kernel exposure to the extrusion and
micronisation processes at the temperature of 100oC. However, a significant
lipoxygenase activity increase was recorded in both studied cultivars after
one-minute microwave heating, i.e. at the temperature about 60?C. A further
temperature increase led to a gradual denaturation of the enzyme and
therefore to its decreased activity.
Plant protection products in organic grapevine growing
Authors: Sivcev Branislava , Sivcev Ivan , Rankovic-Vasic Zorica
Published: December 2010

Pests and grapevine diseases in organic production are suppressed by
preventive measures with a view to reducing the impact of the attack. Allowed
substances acting on patogenous fungi, insects, mites and other harmful
organisms are used, if appropriate. Insecticides of plant origin are used in
the organic production of grapevine, as well as vegetable oils, powders and
insecticidal soaps that are selective, with a narrow range of effects and of
lower toxicity, as well as biological products. As a rule, such plant
protection products require a more frequent application. Copper-based and
sulphur-based fungicides are still leading products in suppressing grapevine
diseases. Researches are directed to decrease the quantity of application and
to find their replacement by also efficient fungicides. A special emphasis is
put on researching the efficient fungicides for suppressing Botrytis bunch
rot and factors causing grapevine wood diseases (Esca and Eutypa) in organic
production. Along with copper and sulphur, different substances such as
bicarbonates, plant extracts and oils, biological products being parasites,
patogenous or diseases agent antagonists, and natural products such as milk
and whey are applied in the organic production of grapevine.

AR(1) time series with approximated Beta marginal
Authors: Popovic Bozidar
Published: December 2010

We consider the AR(1) time series model Xt ? ?Xt?1 = ?t, ??p ? N \ {1}, when
Xt has Beta distribution B(p, q), p ? (0, 1], q > 1. Special attention is
given to the case p = 1 when the marginal distribution is approximated by
the power law distribution closely connected with the Kumaraswamy
distribution Kum(p, q), p ? (0, 1], q > 1. Using the Laplace transform
technique, we prove that for p = 1 the distribution of the innovation
process is uniform discrete. For p ? (0, 1), the innovation process has a
continuous distribution. We also consider estimation issues of the model.
On the Selberg integral of the k-divisor function and the 2k-th moment of the Riemann zeta-function
Authors: Coppola Giovanni
Published: December 2010

In the literature one can find links between the 2k-th moment of the Riemann
zeta-function and averages involving dk(n), the divisor function generated
by ?k(s). There are, in fact, two bounds: one for the 2k-th moment of ?(s)
coming from a simple average of correlations of the dk; and the other, which
is a more recent approach, for the Selberg integral involving dk(n),
applying known bounds for the 2k-th moment of the zeta-function. Building on
the former work, we apply an elementary approach (based on arithmetic
averages) in order to get the reverse link to the second work; i.e., we
obtain (conditional) bounds for the 2k-th moment of the zeta-function from
the Selberg integral bounds involving dk(n).
Mexican Adolescents' Comprehension about Bank Functions: Considerations regarding the Development of School Curricula
Authors: Diez-Martinez Evelyn , Delval Juan
Published: December 2010

Mexican secondary and high school curricula do not include any economic or financial education. Furthermore, Mexico's actual banking infrastructure is not widely spread around all of the country, and several towns and villages still do not have banks. Hence it becomes difficult for adolescents to understand these institutions, which are important in the socio-economic organization of societies. In order to provide research data about levels of comprehension among adolescents of these topics, so that it can eventually be considered by Mexican authorities that produce school curricula, it was decided to develop a pilot study with a sample of 25 adolescents between 12 and 16 years of age from a middle-class socio-economic context, who were individually interviewed about bank functioning, interest rates and the difference between credit and debit cards. Subjects were tested individually in their schools by the researchers and the interviews lasted approximately 25 minutes. All interviews were audio taped and later transcribed. Results show that the majority of subjects understand interest rates on loans but cannot relate them to interest rates on deposits. They also confuse credit and debit cards. Data are discussed in terms of levels of comprehension and possible application to school curricula.
3D quantum mechanical simulation of square nanowire MOSFETs by using NEGF method
Authors: Dastjerdy Esmaeil , Ghayour Rahim , Sarvari Hojjat
Published: December 2010

In order to investigate the specifications of nanoscale transistors, we have used a three dimensional (3D) quantum mechanical approach to simulate square cross section silicon nanowire (SNW) MOSFETs. A three dimensional simulation of silicon nanowire MOSFET based on self consistent solution of Poisson-Schrödinger equations is implemented. The quantum mechanical transport model of this work uses the non-equilibrium Green’s function (NEGF) formalism. First, we simulate a double-gate (DG) silicon nanowire MOSFET and compare the results with those obtained from nanoMOS simulation. We understand that when the transverse dimension of a DG nanowire is reduced to a few nanometers, quantum confinement in that direction becomes important and 3D Schrödinger equation must be solved. Second, we simulate gate-all-around (GAA) silicon nanowire MOSFETs with different shapes of gate. We have investigated GAA-SNW-MOSFET with an octagonal gate around the wire and found out it is more suitable than a conventional GAA MOSFET for its more I
on/I
off, less Drain-Induced-Barrier-Lowering (DIBL) and less subthreshold slope.
Photocatalytic properties of nanocrystalline TiO2 thin films doped with Tb
Authors: Wojcieszak Damian , Kaczmarek Danuta , Domaradzki Jaroslaw , Prociow Eugeniusz , Morawski Antoni , Janus Magdalena
Published: December 2010

In this work photocatalytic properties of TiO2 thin films doped with different amount of Tb have been described. Thin films were prepared by high energy reactive magnetron sputtering process. Comparable photocatalytic activity has been found for all doped TiO2 thin films, while different amounts of Tb dopant (0.4 and 2.6 at. %) results in either an anatase or rutile structure. It was found that the terbium dopant incorporated into TiO2 was also responsible for the amount of hydroxyl groups and water particles adsorbed on the thin film surfaces and thus photocatalytic activity was few times higher in comparison with results collected for undoped TiO2 thin films.

Published: December 2010

The lithography is a basic microelectronic process which determines properties of fabricated device. The resolution of optical lithography applied nowadays is insufficient for creating high resolution patterns such as gate electrode in transistors. The scaling ability is the major motivation for undertaking experiments to elaborate high resolution lithography techniques. The atomic force microscope (AFM) is commonly used as tool for creation patterns in sub-micrometers resolution. In this paper, the results of simulations of electromagnetic field behavior during passing the gap with a size smaller than the wavelength of the optical lithography light source are presented. Also results of the nanoscratching lithography prepared for various parameters of force that are applied to the tip are summarized.

This is an epidemiologic study of the Slovak population with the aim of determining the frequencies of three hemochromatosis gene (HFE) variants C282Y, H63D and S65C known to be associated with manifestation of hereditary hemochromatosis and to assess deviations of these frequencies from those reported elsewhere. Mutations were detected in 359 ethnic Slovaks by real-time PCR assay based on TaqMan technology. The allelic frequencies were 4.03% for C282Y, 12.67% for H63D and 1.25% for S65C mutation. We observed 0.28% of C282Y/C282Y homozygotes, 3.34% H63D/H63D homozygotes, 0.84% of C282Y/H63D compound heterozygotes and 0.56% of H63D/S65C compound heterozygotes. This is the first time the frequencies of H63D and S65C mutations have been reported in the general population in Slovakia. The observed allelic frequencies are consistent with the previous studies of Slavic and Central European populations.
Optic neuritis and paranasal sinus diseases
Authors: Čelakovský P. , Vokurka J. , Školoudík L. , Růžička J.
Published: December 2010

The relationship of sinusitis and paranasal sinus mucoceles to optic neuritis (ON) remains a challenge for both the otolaryngologist and the ophthalmologist. Currently, ON is assumed to be a rare complication of paranasal sinus diseases. Three new cases of ON associated with paranasal sinus diseases are described. We postulate different pathophysiologic mechanisms of ON in our three patients: compression of optic nerve due to sphenoid mucocele in the first patient; extension of bacterial infection to the optic nerve in the second patient; and invasion of aspergillosis to the orbital apex in the third patient. We assume that the complete recovery of the patient’s vision in the second case resulted from surgery, which had been performed immediately. A timely operation could possibly have prevented permanent blindness in cases 1 and 3 as well. Optic neuritis can occasionally be a complication of bacterial and mycotic sinusitis or paranasal sinus mucoceles, especially if located in the sphenoid sinus and posterior ethmoids. The evaluation of paranasal sinuses using imaging techniques is necessary to diagnose the problem, and immediate surgery can prevent permanent sequelae in indicated cases.
Theoretical study on transesterification in a combined process consisting of a reactive distillation column and a pervaporation unit
Authors: Švandová Zuzana , Markoš Jozef
Published: December 2010

Steady state analysis of a combined hybrid process consisting of a reactive distillation column, pervaporation unit, and a distillation column is presented. This process configuration was first presented by Steinigeweg and Gmehling (2004) for the transesterification of methyl acetate and butanol to butyl acetate and methanol. This system is characteristic for its low reaction rate and complex phase equilibrium. Steinigeweg and Gmehling (2004) have shown that the combination of reactive distillation and pervaporation is favourable since conversions close to 100 % can be reached with a reasonable size of the reactive section in the reactive distillation column. The aim of this paper is to show that although high conversion can be achieved, very complicated steady state behaviour must be expected. The presented analysis is based on mathematical modelling of a process unit, where the steady-state analysis, including continuation and bifurcation analyses, was used. Multiple steady states were predicted for the studied system; three steady states with conversions higher than 98 %. However, not all predicted steady states met the maximal allowed temperature condition in the reactive section (catalyst maximal operation temperature of 393 K). The presence of multiple steady states reduces the operability and controllability of the reactive distillation column during its start-up and during the occurrence of any variation of operating parameters because the system can be shifted from one steady state to another one (concurrent exceeding the maximal allowed temperature) with unwanted consequences, e.g. production loss. Therefore, design and subsequent operation of such a complicated system is an ambitious task requiring knowledge of any possible system behaviour.

Validated RP-HPLC and TLC methods for simultaneous estimation of tamsulosin hydrochloride and finasteride in combined dosage forms

Reversed-phase high-performance liquid chromatography (RP-HPLC) and thin-layer chromatography (TLC) methods have been developed and validated for simultaneous estimation of tamsulosin hydrochloride and finasteride in bulk drug and in combined dosage forms. RP-HPLC separation was achieved on a Phenomenex C18column using methanol/0.02 mol L-1ammonium acetate buffer/triethylamine (79.9 + 20 + 0.1,V/V/V) (pH 9.2) as mobile phase. TLC separation was achieved on an aluminium-backed layer of silica gel 60 F254using toluene/methanol/triethylamine (9 + 1.5 + 1,V/V/V) as eluent. Quantification was achieved with photodiode array (PDA) detection at 235 nm over the concentration range 0.5-16 and 1-50 μg mL-1with mean recovery of 99.8 ± 0.9 and 100.0 ± 0.8% for tamsulosin hydrochloride and finasteride, respectively, by the RP-HPLC method. Quantification was achieved with UV detection at 270 nm over the concentration range 100-2000 ng per spot and 250-5000 ng per spot with mean recovery of 98.9 ± 0.9 and 99.6 ± 0.7 % for tamsulosin hydrochloride and finasteride, respectively, by the TLC method. Both methods are simple, precise, accurate and sensitive and are applicable to the simultaneous determination of tamsulosin hydrochloride and finasteride in bulk drug and in combined dosage forms.

FPGA Adaptive Predistorter Based on 64QAM Modulation

This paper presents a predistortion technique compensating for nonlinear distortions caused by HPA (High Power Amplifier) in a QAM (Multilevel Quadrature Modulation) system. Investigations were held both with software and hardware tools. It is confirmed by computer simulation that proposed approach produces a faster convergence speed than traditional computer performed algorithms. Predistortion technique based on programmable logic device is a very attractive from the implementation point of view, because of a low amount of required RAM and rapid convergence from a blind start.

A Procedure for Quasi-Equiripple Linear-Phase IIR Filters Design

The linear-phase IIR filters are described in many cases, mainly due to distortion-free transmission of signals. One of the major problems of IIR filter design is stability, which can be obtained with suitable value of group delay τ. This paper concerns calculation of filter orderNand group delay τ in case of quasi-equiripple design of IIR filters. We propose a novel procedure for determiningNand τ values; the procedure is valid for all types of filters with arbitrary number of zeros and a few non-zero poles. Evaluation of the proposed approach as well as examples illustrating its application are provided in the paper.

Fast Determination of Similarity Between Two Vectors by Means of Analog CMOS Technique

In this paper, an analog approach to determining a resemblance between two multidimensional vectors is proposed. As the resemblance measure, Euclidean distance is used. The main advantage of the presented method is a very high speed of the Euclidean-distance-measure calculations. The achieved high speed results from the fact that most of arithmetic operations needed to realize the calculations are carried out in parallel. This concerns the required operations of squaring a difference of two corresponding components of the compared vectors. Operating in a transconductane mode (voltage difference squaring transconductors) and a current mode (output square-root extracting circuit), our CMOS circuit is power saving. Its low-power operation results from the fact that sub-circuits of our calculator responsible for the squaring operations (a great number of them in case of large multidimensional vectors) consume no power in the absence of input signals. This takes place when corresponding components of the compared vectors are both equal to zero. The circuit also consumes a reasonably low amount of energy when processing (comparing) a different from zero input data (corresponding vector components). A simplified description of the applied differential squaring transconductors as well as the output current-mode square-root extraction circuit is given and a problem of good cooperation between them is discussed and proper solutions indicated. SPICE simulation results are shown to be in a good agreement with the theory presented.

Trajectory Estimation for Wireless Mobile Networks Using Polynomial Regression

Arbitrary and random motion of mobile ad hoc network nodes while communicating results in frequent topology changes and multiple disconnections of links. This dynamic environment challenges the routing of data from the source to the destination and imposes the need for prediction models to track these changes, and then determine future topology of the network. The prediction of network mobility into the future will reduce the frequency of location updates for geographical routing protocols. Moreover it will reduce route request delay and the frequency of route updates in topology based protocols. This paper proposes a predictive model called polynomial regression trajectory estimation. This model is based on the regular behavior of nodes and uses polynomial regression to allow each mobile node to estimate its future locations as a function of time. The estimated locations will be disseminated to the network so that nodes can use them to estimate the future topologies of the entire network. The efficiency of the proposed model has been evaluated by MATLAB simulation.

The Forensic Gothic: Knowledge, the Supernatural, and the Psychic Detective
Authors: McGuire Ann , Buchbinder David
Published: December 2010

Abstract:

This article analyses two television series first screened in 2005: Medium and Supernatural. It argues that, in the context of post-9/11 anxieties about the surveillance and defence of the borders of nation/family, the narrative use of paranormal phenomena offers a new forensic model. While traditional detective narratives rely on empiricist, Enlightenment ways of identifying and defending against the invisible, threatening other—making it visible and hence allaying the fears that it excites—these programs, drawing on the narrative strategies of both the detective story and the Gothic tale, offer a way of knowing the unknown and seeing the unseeable.

Gazing Into the Crystal Ball: Where Should the Veterinary Profession Go Next?
Authors: Summerlee Alastair J.S.
Published: December 2010

The Foresight Report, published in 2007, provided a vision for the future of the veterinary profession. Many of the directions set in the report have already been remarkably accurate, but fiscal constraints stemming from the global recession that began in 2008 will have a significant impact on academia and on the future of the veterinary profession. Three primary forces will shape veterinary education in the coming decade: (1) the urgent need to lead an integrated approach to animal, human, and environmental health; (2) the continued information explosion; and (3) the challenge of delivering high-quality veterinary clinical training at a time of fiscal restraint. Despite economic woes and financial pressure, this is the time to rethink veterinary medical education. This article outlines these challenges and suggests ways to continue to evolve veterinary education.

Awareness of student learning-style preferences is important for several reasons. Understanding differences in learning styles permits instructors to design course materials that allow all types of learners to absorb and process information. Students who know their own learning style are better able to help themselves in courses taught in a non-preferred method by developing study strategies in line with their preferred learning method. We used the Felder and Solomon Index of Learning Styles to assess the learning-style profiles of 150 veterinary students in three consecutive years. Students were predominantly active (56.7%), sensing (79.3%), visual (76.7%), and sequential (69.3%). Most were balanced on the active–reflective (59.3%) and global–sequential (50%) dimensions, and 61.3% and 54% were moderately to strongly sensing and visual, respectively. Small but significant numbers of students were moderately to strongly intuitive (8.7%), verbal (13%), and global (12%). The most common patterns were active–sensing–visual–sequential (26%), reflective–sensing–visual–sequential (19.3%), active–sensing–visual–global (8.7%), and active–sensing–verbal–sequential (8.7%). Although most students (65.3%) were balanced on one to two dimensions, 77.3% had one or more strong preferences. Our results show that although people have dominant learning-style preference and patterns, they have significant minor preferences and patterns across all dimensions with moderate to strong preferences on each scale. These results indicate that a balanced approach to teaching is essential to allow all students to learn optimally.
North American Veterinary Licensing Examination Pacing Study

Published: December 2010

The National Board of Veterinary Medical Examiners was interested in the possible effects of word count on the outcomes of the North American Veterinary Licensing Examination. In this study, the authors investigated the effects of increasing word count on the pacing of examinees during each section of the examination and on the performance of examinees on the items. Specifically, the authors analyzed the effect of item word count on the average time spent on each item within a section of the examination, the average number of items omitted at the end of a section, and the average difficulty of items as a function of presentation order. The average word count per item increased from 2001 to 2008. As expected, there was a relationship between word count and time spent on the item. No significant relationship was found between word count and item difficulty, and an analysis of omitted items and pacing patterns showed no indication of overall pacing problems.
