Published: September 2009

A total of 117 diabetic patients aged 20-65 years suffering from diabetes for at least one year were enrolled in this cross-sectional study. The study was conducted in Nawabganj Diabetic Center, a branch of Bangladesh Diabetic Association during the period from March 2001 to June 2001. The aim of the study is to assess the nutritional status of diabetic patients, which may contribute useful information for more comprehensive and intensive approach to diabetic patients care. Majority (64%) of the respondents were normal (BMI 18.5-24.99) in nutritional status followed by overweight (31%, BMI > 25) and underweight (4.3%, BMI < 18.5). Middle age group appeared to suffer more from diabetes with no sex difference irrespective of age (males: 50.4%, females: 49.6%). Diabetic care seeking behaviour by rural people and females (housewives) appeared encouraging emphasizing the need of decentralization of diabetic care center to periphery. More retired persons (50%) and housewives (32%) showed obesity (40%) and no underweight with high family income might be explained as an association of more calorie intake and less physical activities. Among the diabetic patients, retired persons and housewives appeared particularly vulnerable to become obese and on the other hand younger patients, poor education, lower income group and patients consuming low calorie were prone to develop under nutrition. So health education should be aimed to enhance awareness of particularly rural and illiterate people for regular visit to nearby diabetic center and to strictly adhere to dieticians' advice. doi: 10.3329/taj.v17i2.3451 TAJ 2004; 17(2): 89-92

Published: September 2009

Kala-azar is a re-emerging global problem. Recent years have shown a notable improvement in both morbidity and mortality in patients with Kala-azar. Much of this benefit is derived from the use of the newer therapeutic agents. Among these Amphotericin-B deoxycholate for the treatment of resistant Kala-azar is very effective and offer many advantages. We report a case of resistant Kala-azar where we used Amphotericin-B deoxycholate and it showed a very good clinical and parasitological response. doi: 10.3329/taj.v17i2.3459 TAJ 2004; 17(2): 110-112
The Breast Cancer Genes
Authors: Haque MM , Sarkar S , Mallick AK 
Published: September 2009

Breast cancer, almost exclusively a disease of the women, accounts for 10% of 10 million new cancer cases each year and causes 370,000 deaths annually although the incidence in Asia is low. Risk factors for breast cancers belong to different domains. Those associated with the highest relative risk belong to the genetic domain. The only group of women with mutated breast cancer genes had an average lifetime risk of developing breast cancer was calculated to be 65.3%. Genetic counseling and genetic study might help surgeons as well as the patients to better estimate the risk of developing breast cancer disease. doi: 10.3329/taj.v17i2.3461 TAJ 2004; 17(2): 117-120

Published: September 2009

ABSTRACTWe have carried out spectral induced polarization (IP) measurements at three different hydrogeological test sites (Hasloh, Lüdingworth and Kappelen) and estimated hydraulic conductivity using empirical equations previously derived from laboratory measurements. We also reviewed previously published data from another site (Krauthausen). The intention was to explore the potential and practical limitations when applying the method at the field scale. The test sites cover a lithological spectrum from gravel to silt, with a variation in hydraulic conductivity over three orders of magnitude. At each site, hydraulic conductivity was estimated from the real and imaginary conductivity resulting from 2D inversion. We applied the constant phase angle model, where only one frequency, typically around 1 Hz is being used. The uncertainty in ‐estimates arising from inversion ambiguity was assessed by exploring the model space with a control parameter that permits a transition from smooth to blocky models and by using different starting models. At the Kappelen site, this uncertainty is larger than four orders of magnitude but a reasonable lower limit for can be obtained. At the other three sites, the uncertainties are typically one order of magnitude.The IP‐based hydraulic conductivity estimates were compared with K‐values obtained from grain size analyses and pumping tests. At the Hasloh and Lüdingworth sites the results agree within one order of magnitude and at the Kappelen site the derived lower boundary for is consistent with grain size information. At the Krauthausen site, the difference between IP‐based data and the values derived from grain size and pumping tests is significantly larger than the estimated uncertainties, which is probably due to the non‐uniform grain size distribution. The overall results indicate that order of magnitude ‐estimates from IP data at the field scale are realistic targets. However, sites with significant deviations from the empirical equations can exist, emphasizing the recommendation to use a priori information whenever possible.
Self‐esteem memories and school success in early adolescence
Authors: Ivcevic Zorana , Pillemer David B. , Brackett Marc A. 
Published: September 2009

AbstractEarly adolescents recounted experiences when they felt ‘especially good’ or ‘especially bad’ about themselves in the past year. Consistent with prior research using adult participants, negative memories focused primarily on social themes, whereas positive memories also prominently included achievement themes. Girls described more social themes than did boys for both positive and negative memories. The content of self‐esteem memories was related to teachers' formal assessments of adolescents' social and academic functioning: The presence of achievement themes in positive and negative memories was associated with more positive teacher ratings.

Laterality in semi‐free‐ranging black and white ruffed lemurs (Varecia variegata variegata): head‐tilt correlates with hand use during feeding
Authors: Nelson Eliza L. , O'Karma Jaime M. , Ruperti Felicia S. , Novak Melinda A. 
Published: September 2009

AbstractPrevious studies in human and chimpanzee infants have identified a predictive relationship between early rightward head orientation and later right hand use. Data from lemurs suggest a leftward bias in hand preference, but there are no data on head positioning. The purpose of this study was to examine the relationship between head and hand preferences in the black and white ruffed lemur (Varecia variegata variegata). Ruffed lemurs rotate the head vertically during chewing in a behavior called head‐tilting. Frequency of head‐tilting and bouts of unimanual hand use were measured during normal feeding in a semi‐free‐ranging population of lemurs. Subjects were provisioned at feeding platforms twice daily with fresh fruits, vegetables, and other food items. Sampling was spontaneous and all observations were videotaped. No group‐level bias was found for head‐tilting, but a left hand bias emerged for hand use. A positive relationship was found between direction of head‐tilting preference and direction of hand use preference such that left head‐tilts increased as left hand use increased. Furthermore, left head‐tilts increased as the degree of hand preference lateralization increased. When the hand used to bring food to the mouth just before head‐tilting was examined, there was a strong bias for the left hand to precede left head‐tilts. For right head‐tilts, however, lemurs were equally likely to use either hand before head‐tilting. Overall a strong relationship was found between the left hand and left head‐tilting in black and white ruffed lemurs, suggesting a common link between these behaviors. However, the direction of bias was different from that seen in human and chimpanzee studies. Additional studies on patterns of laterality would be informative for understanding how laterality has changed across the primate order and the adaptive significance of laterality in primates. Am. J.

The Karlson Lecture. Phytoecdysteroids: What use are they?
Authors: Dinan Laurence 
Published: September 2009

AbstractPhytoecdysteroids are analogues of arthropod steroid hormones found in plants, where they deter predation by non‐adapted predators. There is potential to exploit this to develop new strategies for pest control, either by using ecdysteroids as lead molecules for the design of novel pest control agents or by alteration of ecdysteroid levels/profiles in crop plants through plant breeding or genetic modification. However, it is other properties of phytoecdysteroids that have led to a rapid recent increase in scientific and commercial interest in these molecules. They are apparently non‐toxic to mammals and a wide range of beneficial pharmacological (adaptogenic, anabolic, anti‐diabetic, hepatoprotective, immunoprotective, wound‐healing, and perhaps even anti‐tumour) activities is claimed for them. In particular, this has led to a large (and unregulated) market for ecdysteroid‐containing preparations for body‐builders, sportsmen, and pets, among others. Ecdysteroids are also being considered as nutraceutical additives to food products. Further, ecdysteroids are good candidates as elicitors for gene‐switch systems to be used in medical gene therapy and research applications. In this article, I review the applications of phytoecdysteroids and assess their future potential. © 2009 Wiley Periodicals, Inc.
Maximum entropy probability method applied to assess voltage sag frequency due to transmission line fault in the electric power system
Authors: Xiao Xian‐Yong , MA Chao , Yang Hong‐Geng , Li Hua‐Qiang 
Published: September 2009

AbstractVoltage sag caused by faults on an electric power transmission line is one of the most intractable power quality issues for both utility companies and customers. The fault in power system randomly exists along transmission lines due to the combination of many uncertain factors. To predict and assess the annual expected sag frequency (ESF) deriving from the faults along lines, a stochastic‐based method that employs maximum entropy principle, namely the maximum entropy probability method (MEPM), has been introduced in this paper. Moreover, various types of faults have been considered systematically. With the fault line intervals and the sample moments taken into account, the discrete values of distribution probability of fault locations along the transmission lines have been estimated by means of the MEPM. For a given voltage sag magnitude corresponding to the voltage tolerant level of sensitive equipment at the tested bus, the ESF has been calculated in view of the statistical fault rates of interrelated transmission lines. The implementation and application to a classical five‐bus system and IEEE RTS‐30 test system have been presented consequently. The simulations have revealed that compared with the four existing methods, the MEPM is accurate, flexible, and immune of round‐off errors, and therefore it can be widely applied to the various aspects of power systems.

Comparing performances of logistic regression and neural networks for predicting melatonin excretion patterns in the rat exposed to ELF magnetic fields

Published: September 2009

AbstractVarious studies have been reported on the bioeffects of magnetic field exposure; however, no consensus or guideline is available for experimental designs relating to exposure conditions as yet. In this study, logistic regression (LR) and artificial neural networks (ANNs) were used in order to analyze and predict the melatonin excretion patterns in the rat exposed to extremely low frequency magnetic fields (ELF‐MF). Subsequently, on a database containing 33 experiments, performances of LR and ANNs were compared through resubstitution and jackknife tests. Predictor variables were more effective parameters and included frequency, polarization, exposure duration, and strength of magnetic fields. Also, five performance measures including accuracy, sensitivity, specificity, Matthew's Correlation Coefficient (MCC) and normalized percentage, better than random (S) were used to evaluate the performance of models. The LR as a conventional model obtained poor prediction performance. Nonetheless, LR distinguished the duration of magnetic fields as a statistically significant parameter. Also, horizontal polarization of magnetic fields with the highest logit coefficient (or parameter estimate) with negative sign was found to be the strongest indicator for experimental designs relating to exposure conditions. This means that each experiment with horizontal polarization of magnetic fields has a higher probability to result in “not changed melatonin level” pattern. On the other hand, ANNs, a more powerful model which has not been introduced in predicting melatonin excretion patterns in the rat exposed to ELF‐MF, showed high performance measure values and higher reliability, especially obtaining 0.55 value of MCC through jackknife tests. Obtained results showed that such predictor models are promising and may play a useful role in defining guidelines for experimental designs relating to exposure conditions. In conclusion, analysis of the bioelectromagnetic data could result in finding a relationship between electromagnetic fields and different biological processes.

Published: September 2009

AbstractWe investigated the effect of mobile phone use on the auditory sensory memory in children. Auditory event‐related potentials (ERPs), P1, N2, mismatch negativity (MMN), and P3a, were recorded from 17 children, aged 11–12 years, in the recently developed multi‐feature paradigm. This paradigm allows one to determine the neural change‐detection profile consisting of several different types of acoustic changes. During the recording, an ordinary GSM (Global System for Mobile Communications) mobile phone emitting 902 MHz (pulsed at 217 Hz) electromagnetic field (EMF) was placed on the ear, over the left or right temporal area (SAR1g = 1.14 W/kg, SAR10g = 0.82 W/kg, peak value = 1.21 W/kg). The EMF was either on or off in a single‐blind manner. We found that a short exposure (two 6 min blocks for each side) to mobile phone EMF has no statistically significant effects on the neural change‐detection profile measured with the MMN. Furthermore, the multi‐feature paradigm was shown to be well suited for studies of perception accuracy and sensory memory in children. However, it should be noted that the present study only had sufficient statistical power to detect a large effect size. Bioelectromagnetics 31:191–199, 2010. © 2009 Wiley‐Liss, Inc.
Millimeter wave effects on electrical responses of the sural nerve in vivo

Published: September 2009

AbstractMillimeter wave (MMW, 42.25 GHz)‐induced changes in electrical activity of the murine sural nerve were studied in vivo using external electrode recordings. MMW were applied to the receptive field of the sural nerve in the hind paw. We found two types of responses of the sural nerve to MMW exposure. First, MMW exposure at the incident power density ≥45 mW/cm2 inhibited the spontaneous electrical activity. Exposure with lower intensities (10–30 mW/cm2) produced no detectable changes in the firing rate. Second, the nerve responded to the cessation of MMW exposure with a transient increase in the firing rate. The effect lasted 20–40 s. The threshold intensity for this effect was 160 mW/cm2. Radiant heat exposure reproduced only the inhibitory effect of MMW but not the transient excitatory response. Depletion of mast cells by compound 48/80 eliminated the transient response of the nerve. It was suggested that the cold sensitive fibers were responsible for the inhibitory effect of MMW and radiant heat exposures. However, the receptors and mechanisms involved in inducing the transient response to MMW exposure are not clear. The hypothesis of mast cell involvement was discussed.

MPI support on opportunistic grids based on the InteGrade middleware
Authors: Cardoso M. C. , Costa F. M. 
Published: September 2009

AbstractThe message passing interface (MPI) is a popular programming model for parallel applications. Support for MPI in grid middleware is important for the widespread use of grids for parallel programming. This enables existing parallel applications to be executed on large‐scale grids, as opposed to being restricted to local clusters. In the specific case of opportunistic grids, the use of idle computing power from non‐dedicated computers further adds to the range of resources that can be used. In this paper we present MPICH‐IG, an implementation of the MPI‐2 standard on top of the InteGrade grid middleware. Existing MPI applications can run unmodified, while taking advantage of the InteGrade scheduler to harvest the available computing power from the grid. In addition, fault‐tolerance of MPI applications is achieved through a checkpointing mechanism, which allows applications to be resumed after failures of particular grid nodes.

A reference model for grid architectures and its validation
Authors: van der Aalst Wil , Bratosin Carmen , Sidorova Natalia , Trčka Nikola 
Published: September 2009

AbstractComputing and data‐intensive applications in physics, medicine, biology, graphics, and business intelligence require large and distributed infrastructures to address the challenges of the present and the future. For example, process mining applications are faced with terrabytes of event data and computationally expensive algorithms. Computer grids are increasingly being used to deal with such challenges. However, grid computing is often approached in anad hocand engineering‐like manner. Despite the availability of many software packages for grid applications, a good conceptual model of the grid is missing. This paper provides a formal description of the grid in terms of a colored Petri net (CPN). This CPN can be seen as a reference model for grids as it clarifies the basic concepts at the conceptual level. Moreover, the CPN allows for various kinds of analyses ranging from verification to performance analysis. We validate our model based on real‐life experiments using a testbed grid architecture available in our group and we show how the model can be used for the estimation of throughput times for scientific workflows.

Published: September 2009

AbstractIn this paper, we jointly optimize the position of the relay node and transmission power ratio of the source node over the relay node to minimize the outage probability, which can provide guidance for IEEE 802.16j transparent relay node configuration. The result indicates that the outage probability is minimum when the relay is positioned at the midway between the source and the destination, and the transmission power ratio of the source node over the relay node is 11:9.

Konstruktion und die Ausführung von unbewehrtem Mauerwerk nach DIN 1053‐12
Authors: Figge Dieter 
Published: September 2009

AbstractDie aktuelle und bauaufsichtlich eingeführte Fassung der DIN 1053‐1 [1]: Mauerwerk, Teil 1: Berechnung und Ausführung stammt aus dem Jahr 1996 und regelt bislang in nur einer Norm das vereinfachte und das genauere Nachweisverfahren, sowie die Konstruktion und die Ausführung von Mauerwerk. Eine erstmalige Überarbeitung der Norm erfolgte dann im Jahr 2004 mit der Vorlage der DIN 1053‐100 [2], in der die Umstellung der Berechnung und Bemessung auf das semiprobabilistische Sicherheitskonzept vollzogen wurde. Mit dieser zusätzlichen Norm wurde jedoch keine grundlegende inhaltliche Überarbeitung der Mauerwerksnorm verfolgt, sondern lediglich die Anpassung an das Teil sicherheitskonzept bei unbewehrtem Mauerwerk geregelt. Um den neuen Entwicklungen in den Bereichen Baustoffe, Bemessung sowie Ausführung und Konstruktion zukünftig Rechnung tragen zu können, wurde eine neue DIN 1053 für unbewehrtes Mauerwerk erarbeitet und als Gelbdruck in den Teil en DIN 1053‐11[3], DIN 1053‐12 [4] und DIN 1053‐13 [5] veröffentlicht. So erfolgt die Bemessung nach dem vereinfachte Nachweisverfahren zukünftig nach DIN 1053‐11 [3]: Mauerwerk‐ Teil 11: Vereinfachtes Nachweisverfahren für unbewehrtes Mauerwerk und die genauere Bemessung nach DIN 1053‐13 [5]: genaueres Nachweisverfahren für unbewehrtes Mauerwerk. Die Konstruktion und die Ausführung von unbewehrtem Mauerwerk hat zukünftig einen eigenen Normenteil und wird in DIN 1053‐12 [4] Konstruktion und Ausführung von unbewehrtem Mauerwerk geregelt. Der aktuelle Stand von DIN 1053‐12 [4] enthält eine Reihe von Neuerungen in Bezug auf Änderungen und Neuerungen im Mauerwerksbau und wird in diesem Beitrag vorgestellt und erläutert.
