According to the Government's defense policy, "New Economy Growth Motives of Defense Industries", the relevant bodies set up the objective, 'The Defense Export over 3 billion dollars until 2012' and continue to make the effort to reach this goal today. Therefore, the defense technology valuation is going to be a key issue for the domestic defense R&D of equipment including main battle tanks, armored vehicles, air fighters and so on. This paper presents the defense R&D technology valuation model with the in-depth analysis of its theories and current status both domestic and abroad. Also, it provides relevant policy issues and direction in the near future. It should firmly contribute to boosting the defense technology valuation fields and to formulating a concrete tool for analyzing defense R&D technology valuation in the near future.
A new stroke volume equation for thoracic electrical bioimpedance: Theory and rationale

A new stroke volume equation for thoracic electrical bioimpedance is proposed. This empirically derived formula differs from previous equations in that: a) the thoracic volume conductor is modeled geometrically as a frustum (truncated cone), rather than a cylinder; b) the specific resistivity of blood, p (rho), is appropriately eliminated as an independent variable; c) the equation employs a percentage of overall body height in lieu of a measured thoracic length; and d) a new term, 5, is introduced to scale the parent equation for deviation from ideal body weight.
Analysis of the Effects of Transcription Factors Gcr2p and Sgc1p on the Control of the SUC2 Gene Expression in Saccharomyces cerevisiae

The transcription of the SUC2 gene is regulated by glucose repression and the derepression mechanism in the yeast Saccharomyces cerevisiae. The Mig1p-Tup1p-Ssn6p repressor complex, hexokinase PII and nucleosomes are required for the repression of the SUC2 gene. The Snf/Swi and SAGA complexes act on Mig1p and nucleosomes in low glucose media. SUC2 transcription thus becomes activated. In this study, it is shown that the transcription factors Gcr2p and Sgc1p are also required for the high level transcription of the SUC2 gene. SUC2 transcription and the invertase synthesis decreased at significant levels in gcr2 and sgc1 mutant yeast cells. In addition, it is also shown that the derepression of the SUC2 gene transcription is very slow in gcr2 and sgc1 mutant yeast strains. The glucose repression rate seems to be normal in gcr2 and sgc1 mutants, indicating that Gcr2p and Sgc1p are essential for the high level transcription of the SUC2 gene.

Fabrication of the patterned flexible OLEDs using a combined roller imprinting and photolithography method

A new patterning method has been developed to fabricate the patterned organic light emitting devices (OLEDs) with pixels of 500 /spl mu/m/spl times/300 /spl mu/m on the flexible PET substrates. The patterns of the pixel array were defined in crossed-strip style with ITO anode patterned using a combination of the roller-type imprinting lithography and photolithography (CRIP), followed by wet chemical etching. Compared with the conventional imprint lithography or photolithography, CRIP using the hybrid mold has the advantages of better uniformity, less force, less time-consuming, lower cost and higher aspect ratio.
Studies on the Predisposing Factors of Protein Energy Malnutrition Among Pregnant Women in a Nigerian Community

Protein Energy Malnutrition (PEM) continues to be a major public health problem in developing countries and affects mostly infants, young children, pregnant and lactating mothers. This study was carried on some of the factors that predispose pregnant women to PEM and hence identify groups at greater risk. A total of 1387 pregnant women (910 in the urban area and 477 in the rural areas) were recruited for the study. Anthropometric indices of weight, height and Body Mass Index (BMI) of the pregnant women were measured and semi structured questionnaires were used to elicit information on possible predisposing factors such as age, level of education, parity, child spacing etc. Results obtained showed that the mean weight and height of the rural pregnant women, were significantly (p<0.0001) lower than those of the urban pregnant women. The mean BMI of the rural subjects, was also significantly (p< 0.0027) lower than that of the urban subjects. Analysis of the effect of age showed that the younger age category (24 years and below) had significantly (p<0.0001) lower mean BMI and higher prevalence of PEM while the effect of level of education showed significantly (p<0006) lower mean BMI and higher PEM prevalence among the less educated (no formal and primary education). Those with parity of two, one and primipara showed significantly (p<0.0175) lower mean BMI while child spacing did not have any significant effect on both mean BMI and prevalence of PEM. The implications of these findings are discussed and recommendations made on how to tackle the problem.
Evaluation of In-vitro Antioxidant Potential of Whole Plant of Various Extracts of Trianthema decandra.

The present investigation was to examine the in-vitro antioxidant potential of various extracts of whole plant of Trianthema decandra by different in-vitro methods . The antioxidant activity was determined by DPPH activity, superoxide radical scavenging and iron chelating activity. An IC 50 value was found that methanolic extract of Trianthema decandra is more effective in free radical scavenging activity than that of other two extracts. So, the in-vitro studies clearly showed that the methanolic extract of Trianthema decandra has a significant antioxidant activity. These in-vitro assays indicate that this plant extracts is a better source of natural antioxidant, which might be helpful in preventing the progress of various oxidative stresses.
Sero-epidemiology of toxocariasis in school children

SUMMARY The seroprevalence of toxocariasis was investigated in 2129 school children ranging in age from 4 to 19 years. Infection, as measured by titre, was found to be high compared to values obtained from children in other countries, with 31% having a titre of ≥ 1:50 and 3·1% having titres of ≥ 1:800. Relalionships between seroprevalence and host factors including age, sex and location, and risk factors including geophagia, thumbsucking and pet ownership were explored. Age was found to be a significant factor in relation to infeclion with Toxocara. Males were significantly more infected than females, as were the inhabitants of rural schools versus urban schools. The percentage of seropositive children varied widely from school to school. Geophagia and pet ownership were found to be significantly associated with toxocariasis. Logistic regression analysis was used to model the relative contribution of these factors to infection wilh Toxocara. While this analysis identified factors which were highly significantly associated with Toxocara titre, the odds ratios were generally low indicating ihe low specificity of the model.
Using Research to Identify Academic Dishonesty Deterrents Among Engineering Undergraduates

CYNTHIA J. FINELLI Center for Research on Learning and Teaching North, University of Michigan; Ann Arbor, MI 48109, USA. E-mail: cfinelli@umich.edu The E Research Team, lead by the authors, has conducted several major investigations and has surveyed and/or interviewed over 1500 engineering and non-engineering undergraduates at 23 institutions [http://www.engin. umich.edu/research/e3/]. The team is motivated by decades of work showing engineering students are among the most frequent cheaters as well as by studies indicating a correlation between cheating and unethical professional behavior. The team’s research suggests that the explanation for higher rates of cheating among engineering students may lie in curricular or engineering program cultural differences rather than in differences in opportunities to cheat or in the nature of students entering these disciplines. The team has also identified a willingness of students to engage in dishonest behaviors that have significant punitive consequences, a clear relationship between students’ attitude toward a behavior and their propensity to engage in that behavior, and a strong correspondence between cheating in high school and college and engaging in unethical behaviors in the workplace. As such, to promote integrity it is important to identify key pedagogical interventions. This paper will summarize some of the team’s important research findings and will discuss psychological and physical deterrents to cheating and their apparent effectiveness. The paper translates these findings into practical suggestions for educators and professionals interested in promoting integrity in the curriculum and the classroom.
Outcomes Among Orthopedic Patients in Skilled Nursing Facilities: Does Managed Care Make a Difference?

The use of rehabilitative care has increased greatly. This study evaluates whether managed care affects health outcomes among Medicare orthopedic patients receiving rehabilitative treatments. Managed care versus fee-for-service patients had better outcomes at four months following discharge from skilled nursing facilities. It is important to address predictive factors, such as age, length of hospital stay, debilitation and social living arrangements, which can also influence health outcomes when planning rehabilitative treatment for older patients.
Speed Optimized Multisine Stimuli for Electrochemical Impedance Spectroscopy with a Switched Mode Excitation

The knowledge of the state of a battery is a prerequisite for the battery management system to be able to increase the reliability, lifetime and safety of the entire energy storage system. Impedance spectroscopy is a well-known measurement technique for electrochemical systems. Once the method is implemented in the battery management system and performed online during operation it could provide a monitoring system for the battery pack. In order to perform the measurement online, the time necessary for it has to be as low as possible, which is best achieved with a multisine excitation signal. The distribution of the stimuli frequencies including their amplitudes and phases for such a broadband signal is presented. A reduction of the measurement time to the period of the lowest measurement frequency and an increase in measurement accuracy is achieved. The presented approach assumes that some kind of switched mode amplification is used to generate the stimuli current necessary to perform an impedance spectroscopy. Special attention has been given to narrowband distortions caused by the modulation process when selecting the stimuli frequencies.
The Minnesota Multiphasic Personality Inventory—2 across the Human Immunodeficiency Virus Spectrum

The Minnesota Multiphasic Personality Inventory—2 (MMPI-2) was used to assess individuals’ patterns of psychological symptoms across the spectrum of HIV illness. Two hundred and twenty-five participants in the present sample were administered the MMPI-2, 61 were HIV-seronegative controls, 61 were asymptomatic, 36 were symptomatic, and 67 met criteria for AIDS. Symptomatic HIV-seropositive patients scored higher on the Hypochondriasis, Conversion-Hysteria, and Depression Scales. These differences appeared to be largely due to an increase in somatic complaints rather than an increase in other depressive symptoms. Group differences did not appear to be due to HIV-associated neuropsychological dysfunction. Interpretive strategies for the MMPI-2 and treatment considerations are discussed.
Exact Calculation of Noise Maps and ${g}$ -Factor in GRAPPA Using a ${k}$ -Space Analysis

Characterization of the noise distribution in magnetic resonance images has multiple applications, including quality assurance and protocol optimization. Noise characterization is particularly important in the presence of parallel imaging acceleration with multi-coil acquisitions, where the noise distribution can contain severe spatial heterogeneities. If the parallel imaging reconstruction is a linear process, an accurate noise analysis can be carried out by taking into account the correlations between all the samples involved. However, for ${k}$ -space-based techniques such as generalized autocalibrating partially parallel acquisition (GRAPPA), the exact analysis has been considered computationally prohibitive due to the very large size of the noise covariance matrices required to characterize the noise propagation from ${k}$ -space to image space. Previously proposed methods avoid this computational burden by formulating the GRAPPA reconstruction as a pixel-wise linear operation performed in the image space. However, these methods are not exact in the presence of non-uniform sampling of ${k}$ -space (e.g., containing a calibration region). For this reason, in this paper, we develop an accurate characterization of the noise distribution for self-calibrated parallel imaging in the presence of arbitrary Cartesian sampling patterns. By exploiting the symmetries and separability in the noise propagation process, the proposed method is computationally efficient and does not require large matrices. Under the assumption of a fixed reconstruction kernel, this method provides the precise distribution of the noise variance for each coil’s image. These coil-by-coil noise maps are subsequently combined according to the coil combination approach used in image reconstruction, and therefore can be applied with both complex coil combination and root-sum-of-squares approaches. In this paper, we present the proposed noise characterization method and compare it to previous techniques using Monte Carlo simulations as well as phantom acquisitions.
Phosphorus characterization in feces from broiler chicks fed low-phytate barley diets

The inclusion of low phytate grains in poultry diets can reduce the phosphorus (P) content of poultry feces, but their influence on fecal P composition is not well established. To assess this, 100 male broiler chicks (21 days old) were fed dietary treatments based on either a wild-type barley or one of three low phytate mutant barleys with 59, 62 and 99% reductions in phytate P, compared with the normal barley diet. The birds were housed in raised-floor battery cages with mesh grate floors above fecal collection trays with five birds per pen and five pens per treatment. The birds were fed for 9 days and feces were collected twice a day during the last 2 days of the experiment. Total P concentrations were 14-24% lower in feces from birds fed low phytate barley diets compared with those fed the normal barley diet. Phosphorus digestibility increased (P < 0.05) as phytate in the barley diet decreased. Phosphate was the major P fraction in the feces (69-75% extracted P) regardless of the type of barley fed. Phytate constituted only 3-12% of the P in the feces, indicating its hydrolysis in the bird. Overall, these results suggest that feeding low-phytate barley diets can reduce P concentrations in poultry feces without causing significant changes in P composition.
Acinar cell cystadenoma: A challenging cytology diagnosis, facilitated by moray® micro‐forceps biopsy

Acinar cell cystadenoma is a rare, benign cystic lesion of the pancreas. There have been only a few retrospective reports on its cytological features. We present the first case of acinar cell cystadenoma in a 65‐year‐old woman, diagnosed pre‐operatively by pancreatic cyst fluid cytology and Moray® micro‐forceps biopsy. We emphasize possible diagnostic pitfalls of acinar cell cystadenoma cyst fluid cytology and suggest useful morphologic, immunohistochemical, and other clues to aid in diagnosis. Diagn.

Generation of single photons and Schrödinger kitten states of light

Vi har i dette bachelorprojekt beskæftiget os med lystilstande der er klemte i kvadraturerne, dvs. har formindskede fluktuationer i forhold til standardkvantegrænsen sat af vacuum, og hvorledes disse kan frembringes eksperimentelt. Disse lystilstande betragtes som værende distinkt kvantemekaniske eller ikke-klassiske, og er af stor interesse indenfor kvanteoptik og kvanteoptiske virkeliggørelser af kvanteinformative kredsløb. I dette projekt introducerer vi disse tilstande og forklarer hvorledes de kan beskrives gennem eksempelvis en kvasisandsynlighedsfordeling ved navn Wigner-funktionen. Hovedvægten er dog lagt på hvorledes disse tilstande bliver skabt i laboratoriet og hvorledes man kan måle dem. Eftersom den eksperimentielle opstilling brugt til at fremstille disse tilstande er ganske indviklet, vil vi i særdeleshed fokusere på underprocessen frekvensfordobling, hvori lys sendes gennem et ikke-linæert krystal og derved frembringer lys af den halve bølgelængde. Denne proces er beskrevet både teoretisk og eksperimentielt, og vi har grundigt karakteriseret den i forsøget benyttede frekvensfordobler igennem målinger af bl.a. dens omdannelseseffektivitet og finesse. Efter denne gennemgang præsenterer vi de af det klemte lys målte data, der viser at klemningen er lykkedes. Disse data præsenteres på flere måder, herunder hører en ikke-triviel proces med at genskabe den målte kvantetilstand ud fra de tilstandsreducerende målinger.
MiRNA-29 a regulates the expression of numerous proteins and reduces the invasiveness and proliferation of human carcinoma cell lines

In this study we have identified a functional role for miR-29a in cancer cell invasion and proliferation. MiRNA expression profiling of human NSCLC cell lines indicated that miR29a levels were reduced in more invasive cell lines. Exogenous overexpression of miR-29a in both lung and pancreatic cancer cell lines resulted in a significant reduction in the invasion phenotype, as well as in proliferation. 2D DIGE proteomic profiling of cells transfected with pre-miR-29a or anti-miR-29a resulted in the identification of over 100 differentially regulated proteins. The fold change of protein expression was generally modest – in the range 1.2–1.7-fold. Only 14 were predicted computationally to have miR-29a seed sequences in their 3 0 UTR region. Subsequent studies using siRNA to knock down several candidate proteins from the 2D DIGE experiment identified RAN (a member of the RAS oncogene family) which significantly reduced the invasive capability of a model lung cancer cell line. We conclude that miR-29a has a significant anti-invasive and anti-proliferative effect on lung cancer cells in vitro and functions as an anti-oncomir. This function is likely mediated through the post-transcriptional fine tuning of the cellular levels of several proteins, both directly and indirectly, and in particular we provide some evidence that RAN represents one
Reduced blood flow to contracting skeletal muscle in ageing humans: is it all an effect of sand through the hourglass?

The ability to sustain a given absolute submaximal workload declines with advancing age, likely to be due to a lower level of blood flow and O2 delivery to the exercising muscles. Given that physical inactivity mimics many of the physiological changes associated with ageing, separating the physiological consequences of ageing and physical inactivity can be challenging; yet, observations from cross‐sectional and longitudinal studies on the effects of physical activity have provided some insight. Physical activity has the potential to offset the age‐related decline in blood flow to contracting skeletal muscle during exercise where systemic blood flow is not limited by cardiac output, thereby improving O2 delivery and allowing for an enhanced energy production from oxidative metabolism. The mechanisms underlying the increase in blood flow with regular physical activity include improved endothelial function and the ability for functional sympatholysis – an attenuation of the vasoconstrictor effect of sympathetic nervous activity. These vascular adaptations with physical activity are likely to be an effect of improved nitric oxide and ATP signalling. Collectively, precise matching of blood flow and O2 delivery to meet the O2 demand of the active skeletal muscle of aged individuals during conditions where systemic blood flow is not limited by cardiac output seems to a large extent to be related to the level of physical activity.
Functional magnetic resonance imaging of auditory cortical fi elds in awake marmosets

The primate auditory cortex is organized into a network of anatomically and functionally distinct processing fields. Because of its tonotopic properties, the auditory core has been the main target of neurophysiological studies ranging from sensory encoding to perceptual decision-making. By comparison, the auditory belt has been less extensively studied, in part due to the fact that neurons in the belt areas prefer more complex stimuli and integrate over a wider frequency range than neurons in the core, which prefer pure tones of a single frequency. Complementary approaches, such as functional magnetic resonance imaging (fMRI), allow the anatomical identification of both the auditory core and belt and facilitate their functional characterization by rapidly testing a range of stimuli across multiple brain areas simultaneously that can be used to guide subsequent neural recordings. Bridging these technologies in primates will serve to further expand our understanding of primate audition. Here, we developed a novel preparation to test whether different areas of the auditory cortex could be identified using fMRI in common marmosets (Callithrix jacchus), a powerful model of the primate auditory system. We used two types of stimulation, band pass noise and pure tones, to parse apart the auditory core from surrounding secondary belt fields. In contrast to most auditory fMRI experiments in primates, we employed a continuous sampling paradigm to rapidly collect data with little deleterious effects. Here we found robust bilateral auditory cortex activation in two marmosets and unilateral activation in a third utilizing this preparation. Furthermore, we confirmed results previously reported in electrophysiology experiments, such as the tonotopic organization of the auditory core and regions activating preferentially to complex over simple stimuli. Overall, these data establish a key preparation for future research to investigate various functional properties of marmoset auditory cortex.
