Dye Degradation by Fungi: An Exercise in Applied Science for Biology Students.

An easily implemented practical exercise in applied science for biology students is presented that uses fungi to degrade an azo-dye. This is an example of bioremediation, the employment of living organisms to detoxify or contain pollutants. Its interdisciplinary nature widens students’ perspectives of biology by exposing them to a chemical engineering process. It also demonstrates the use of biological organisms to degrade a relatively complex chemical, Amaranth. This azo-dye, which is vibrant red across a broad pH range, is safe to employ in the student laboratory. Various species of white rot fungi of the genus Trametes are able to degrade Amaranth to differing degrees, permitting comparative studies. This laboratory exercise involves observations that occur over the course of 3 days, but may be shortened or lengthened, as desired. Results involving decreases in color intensity may be obtained by making comparisons to color standards or by using a spectrophotometer. In our example, we suggest using species of white rot fungi, including Trametes versicolor and Trametes pubescens. The complexity of the lab is easily modified to challenge students of diverse backgrounds because the degree of difficulty of the exercise is adjustable to suite biology non-majors or majors in introductory through advanced courses.
Joint information and energy transfer in the spatial domain with channel estimation error

In this paper, we investigate a new technique for simultaneous information and energy transfer in multiple-input multiple-output (MIMO) networks with radio frequency (RF) energy harvesting (EH) capabilities. The proposed technique exploits the spatial decomposition of the MIMO channel and uses the eigenchannels either to convey information or to transfer energy. In order to generalize our study, we consider channel estimation error in the decomposition process and we model the interference between the eigenchannels. An optimization problem that minimizes the total transmitted power subject to information and energy constraints is formulated as a mixed-integer nonlinear program and solved to optimality by a polynomial complexity algorithm developed by exploiting the special characteristics of the problem. Numerical results show that the imperfect channel estimation is beneficial from RF - EH standpoint and is characterized by an optimal (non-zero) value.
Prevalence of HBV infection in health care personnel.

Madam, I read with interest a short report published in your November, 1994 issue titled ‘Prevalence of HBV Infection in Health Care Personnel’. The report does not clearly defme the studied population, as it was not mentioned that what is the exact numberof doctors. dentists and sweepers employed in the JPMC. Unless whole of the studied population at risk is taken into account the estimation of prevalence remains unreliable. Secondly, it was recommended that all.

Efficacy of daclatasvir in hepatitis C virus

Daclatasvir is a novel NS5A inhibitor of hepatitis C virus (HCV). Daclatasvir combined with peginterferon α-2a and ribavirin in Japanese patients infected with genotype 1b HCV achieved sustained virological response (SVR) in 100% of treatment-naïve patients, due to high rates of favorable IL28B allele and genotype 1b. SVR 24 was achieved by asunaprevir and daclatasvir in 87.4% of intolerant and 80.5% of nonresponder patients. Baseline NS5A-resistant variants were detected and they failed to achieve SVR. Most patients with genotype 1a experienced virological breakthrough by dual oral treatment, and should be treated QUAD or replaced by all oral regimens that are more potent and have fewer side effects. IFN-free regimens including daclatasvir and asunaprevir for genotype 1 null responders should be tailored to subtype, and preexisting NS5A-resistant variants should be evaluated carefully before choosing the drugs. This regimen alone is unlikely to move forward without additional agents.
Lectures on piecewise distance preserving maps

These lectures were a part of the geometry course held during the Fall 2011 Mathematics Advanced Study Semesters (MASS) Program at Penn State (\url{this http URL}). The lectures are meant to be accessible to advanced undergraduate and early graduate students in mathematics. We have placed a great emphasis on clarity and exposition, and we have included many exercises. Hints and solutions for most of the exercises are provided in the end. The lectures discuss piecewise distance preserving maps from a 2-dimensional polyhedral space into the plane. Roughly speaking, a polyhedral space is a space that is glued together out of triangles, for example the surface of a polyhedron. If one imagines such a polyhedral space as a paper model, then a piecewise distance preserving map into the plane is essentially a way to fold the model so that it lays flat on a table. We only consider the 2-dimensional case to keep things easy to visualize. However, most of the results admit generalizations to higher dimensions. These results are discussed in the Final Remarks, where proper credit and references are given.
A Comparison of the Detection Sensitivity of the Poisson Clutter Split and Region of Interest Algorithms on the RadMAP Mobile System

This analysis uses source injection into background data collected by the Radiological Multi-sensor Analysis Platform (RadMAP) to characterize the performance of the Poisson Clutter Split algorithm and compare it with a region-of-interest algorithm. This comparison is performed for varying detector array sizes and false alarm rates using data from Sodium Iodide and High Purity Germanium detector arrays. The application of the Poisson Clutter Split algorithm is found to yield significant performance gains for both medium- and high-resolution detector arrays. Furthermore, trade-offs between energy resolution, array size, cost, and detection performance are explored. In doing so, it is shown that the choice of detection algorithm is a key factor in determining the overall system performance and should be an important consideration in system design.
An Energy Efficient Cost Aware Virtual Machine Migration Approach for the Cloud Environment

— Virtualization is the driving technology in the cloud which allows application isolation and enables the service provider to relocate the virtual machine (VM) from one server (PM) to another, knows as virtual machine (VM) migration. VM migration is the key features of the virtualization. It facilitates load balancing, hot spot mitigation, server consolidation, fault management, and power saving. VM migration is the multi steps process i.e. source PM selection, candidate VM selection, target PM selection and the last step is transferred VM data. This work proposed a priority-based load balancing approach that migrates and schedules the VM according to the weight or priority which is assign to each VM. In the cloud, when the user uses the cloud resources, some amount (bill) is paid by the user for using their resources. On the basis of this bill, some priority is assign to each user.VM which provides more return to the cloud owner will have more priority and schedule first. The main idea of this approach is that gives better service to those users who gives more profit to the provider. The proposed approach is evaluated in CloudSim simulator and experimental results illustrate that proposed approach gives a better result as compare to the competitive approach.
TRPM7 and Ischemic CNS Injury

Ischemic brain damage represents a major source of morbidity and mortality in westernized society and poses a significant financial burden on the health care system. To date, few effective therapies have been realized to treat stroke and once promising avenues such as antiexcitotoxic therapy with NMDA receptor antagonists have not proven clinically useful. Thus, we need to identify new targets for research and therapeutic intervention of the neurodegeneration caused by stroke. Transient receptor potential (TRP) channels are an exciting new family of cation channels that respond to intracellular and extracellular stimuli. Indeed, several members can be induced by oxidative stress and oxygen free radicals. We have recently demonstrated that one member, TRPM7, is an essential mediator of anoxic neuronal death that is activated by oxidative stress, in parallel to excitotoxic signal pathways. Thus, future treatment of ischemic brain injury may need to include strategies that inhibit or modulate TRPM7 activity. Further investigation of the physiology and pathophysiology of TRPM7 and other TRP family members is needed to provide both pharmacological targets and a better understanding of ischemic brain disorders.
Ansiedad y autoconfianza de jóvenes judokas en situaciones competitivas de alta presión

En este trabajo se pretende realizar una aproximacion a los estados de ansiedad y autoconfianza que manifiestan los jovenes judokas en los momentos previos de competiciones con fuerte carga de presion. El objetivo del estudio es determinar si, en este contexto situacional, existen diferencias entre judokas de categoria infantil y judokas de categoria cadete respecto a los valores en ansiedad y en autoconfianza. Han participado un total de 97 judokas varones, de los que 49 pertenecen a la categoria infantil, y 48 a la categoria cadete. La prueba utilizada para evaluar la ansiedad ha sido el Competitive State Anxiety Inventory-2 de Martens, Vealey y Burton (1990) que evalua la ansiedad cognitiva, la ansiedad somatica y la autoconfianza. La administracion de la prueba se realizo durante la celebracion del Campeonato de Espana de Judo. Los resultados muestran diferencias significativas entre la categoria infantil y la cadete respecto a los valores obtenidos en ansiedad cognitiva y en ansiedad somatica (los judokas infantiles presentaban puntuaciones mayores), aunque no sucede asi respecto a los valores obtenidos en autoconfianza. Se discute sobre los procesos adaptativos de los judokas de superior categoria para manejar mejor las demandas estresantes de la competicion, asi como la idoneidad de profundizar en estudios con muestras de judokas jovenes que permitieran conocer mejor el proceso y la evolucion de las manifestaciones de ansiedad y las estrategias o recursos que se pueden utilizar para manejarla.
Quality of life in patients with epilepsy in India

Background: People with epilepsy have impairment in their quality of life (QOL) due to effect of epilepsy on various aspects of their life and the medication effects. Systematic studies on QOL in epilepsy from developing countries are sparse. Objectives: To assess the QOL in people with epilepsy and to evaluate various factors affecting the QOL in them. Materials and Methods: People with generalized and partial epilepsy on medication aged more than 18 years were included in the study. The QOL was assessed with QOLIE-89 instrument. Statistical significance was evaluated by the use of Chi-square test and one-way analysis of variance (ANOVA). Results: Sixty people with epilepsy were studied among whom the older patients had lower overall QOL scores compared to younger patients. Female patients had lower scores compared to males. Married people had lower quality of health score. Patients with simple partial seizures had lowest overall QOL mean score. There was reduction in the overall QOLIE scores with increasing duration of the epilepsy. Patients who had their last seizure within 10 months prior to evaluation had lower mean overall scores. Conclusion: QOL was impaired in people with epilepsy with increased impairment in women, older patients, simple partial seizures, and those with recent seizure.
Real-time identification of NLOS range measurements for enhanced UWB localization

Despite of the ultra-wideband (UWB) system's robustness against multipath in cluttered environments, a number of challenges remain before UWB localization can be implemented. In particular, non-line-of-sight (NLOS) propagation is especially critical for high-resolution localization systems because non-negligibly positive biases will be introduced in distance measurements, thus degrading the localization performance. Here, based on received and first path powers obtainable from channel impulse response (CIR), we propose a simple but very efficient method to distinguish between NLOS and LOS conditions. Our method needs neither the training data nor the prior knowledge about the environments, thus enabling realtime NLOS identification. Despite the simplicity of our method, the experimental results verify its speediness and highly correct detection rate.
Informatik " A region based combinatorial approach for object segmentation in computer vision

Segmentation algorithms for 3D point clouds are used to split scenes into logical entities. In order to reduce the amount of data algorithms have to cope with, methods have been developed to create an oversegmentation without loosing important detail. The aim of the here presented segmentation approach is to combine segments to achieve a partitioning where objects are represented by a single segment. Therefore, in this thesis we developed an algorithm that merges segments from the supervoxel oversegmentation and LCCP segmentation. For this combinatorial step, we propose two algorithms: The first algorithm ("full") combines all segments by brute force and creates all possible combinations. The second one employs neighbourhood information to restrict the combination of segments and combines only neighbouring segments. Afterwards, we evaluate the created hypotheses with an classifier, which will assign a score to all hypotheses. To evaluate the overall method, the overlap between the hypotheses and a manual annotated ground truth is calculated. Both combinatoric algorithms are able to create the correct segmentation of different scenes. The full algorithm is slower, but it can even create correct hypotheses for scenes in which objects are occluded. The recursive neighbouring algorithm is faster, but is unable to create an hypotheses of an object that is "split" due to full occlusion.
Enhancement of MHC Class II-Restricted Responses by Receptor-Mediated Uptake of Peptide Antigens1

Peptides, either as altered peptide ligands, competitors, or vaccines, offer an outstanding potential for regulating immune responses because of their exquisite specificity. However, a major problem associated with peptide therapies is that they are poorly taken up by APCs. Because of poor bioavailability, high concentrations and repeated treatments are required for peptide therapies in vivo. To circumvent this problem, we tested whether covalently coupling a peptide T cell determinant, OVA323–339, to transferrin (Tf) enhances APC uptake and presentation as monitored by Th cell activation. Functional analysis of the Tf-peptide conjugates revealed that the conjugates were presented 10,000- and 100-fold more effectively by B cells than intact Ag and free peptide, respectively. Furthermore, we demonstrate that the Tf-peptide conjugates are taken up by B cells through a receptor-mediated process and subsequently delivered to the lysosomal compartment. Using an adoptive transfer assay, we show that that the Tf-peptide complexes are 100-fold more effective in vivo than the free peptide in activating CD4+ T cells by following an early activation marker, CD69. Our results demonstrate that coupling peptides to Tf enhances peptide presentation, thereby making it possible to take full advantage of peptide-specific therapies in modulating T cell responses.
Implicit Memory Function in Fibromyalgia Syndrome

The study investigated implicit memory function in fibromyalgia syndrome (FMS) and its association with clinical parameters. Implicit memory refers to the influence of past experience on current behavior without conscious awareness of these experiences. Eighteen FMS patients and 25 healthy individuals accomplished a word-stem completion task. As possible factors mediating the expected impairment, pain severity, emotional disorders, and medication were taken into account. The patients displayed markedly reduced task performance and higher levels of depression and anxiety. Among the clinical features, pain severity was most closely associated with performance, whereas depression, anxiety, and medication showed only a minor impact. The study documented reduced implicit memory function in FMS. In contrast to former findings on impaired performance of FMS patients on classical memory tests, lower implicit memory function cannot be ascribed to motivational deficits. Instead, the aberrances may relate to functional inference between central nervous nociceptive activity and cognitive processing.
Effects of herbivore-bearing adult trees of the oak Quercus crispula on the survival of their seedlings

The acorn-producing oak Quercus crispula Blume is shade-tolerant and its seedlings were found to be underdispersed on the forest floor, forming seedling aggregations near fertile canopy trees. However, 84.4% of the seedlings were dead within 2 years, with the highest mortality near the adult canopy trees of Q. crispula. This was mostly due to the high levels of herbivory by lepidopteran larvae. The most serious damage was caused by spring consumers, which fed on the leaves of canopy trees in June and, when the food quality of the leaves declined, fell down to the forest floor to consume the juveniles, including the seedlings. Contrary to the expectation of the herbivore–host arms race theory, most of the herbivores were polyphagous. The most dominant spring consumer Telorta edentata (Leech) was also polyphagous, and its distribution on the forest floor showed a high level of association with the distribution of dead oak seedlings.
PSYOPS et Internet : de l'Irak au Sud-Liban

Nouveau venu dans le champ de l’action psychologique, Internet, tres habilement exploite par les guerillas et groupes terroristes, interesse egalement les armees conventionnelles. Son influence, difficilement mesurable, peut s’exercer directement ou au travers de relais : medias ou citoyens actifs. Sur le web, l’enjeu ne reside pas seulement dans la publication d’une information, mais dans la circulation de cette derniere. Element cle de la Netwar (guerre en reseau), la lutte d’influence sur Internet en reproduit la principale caracteristique : l’avantage competitif dont beneficient sur ce terrain les organisations reticulaires. Propre a faciliter les visees subversives, le Web est donc un enjeu crucial pour les armees conventionnelles. Une etude des conflits Israel - Hezbollah (juillet 2006) et irakien permet d’approfondir l’etude de ce mode d’influence.
Prophylaxis of cognitive functions disorders progressing with age in women.

Numerous structures of the central nervous system are responsible for cognitive functioning. The cortex is responsible for the accumulation of long-term memory. The hippocampus participates primarily in the formation of short-term episodic memory. The amygdala is involved in the formation of emotional memory. In the shell are collected the recordings of our procedural memory, memory of skills, while the caudate nucleus is responsible for our instinctive behaviour, i.e. the genetic memory. Cognitive functioning depends on the efficient co-functioning of the above-mentioned structures of the encephalon. Studies in the area of neurobiology indicate that the region where there occur the first changes related with ageing is the so-called prefrontal cortex and parietal lobes [1, 2].
No pain, no gain? Thoughts on the Caerphilly study

Greater duration and/or intensity of activity can bring additional health benefits The Caerphilly study1 addresses an important question regarding physical activity and health: how intensely does one need to exercise in order to reduce the risk of premature mortality from cardiovascular disease (CVD)? In this study, 1975 men, aged 49–64 years and free of coronary heart disease (CHD), reported on their leisure time physical activities and were followed for an average of 10.5 years for mortality. The investigators concluded that “only leisure exercise classified as heavy or vigorous was independently associated with reduced risk of premature death from CVD”. When men were categorised into thirds of energy expended on vigorous activities requiring ⩾6 METs, the most active third (expending ⩾24 kcal/day in vigorous activities) experienced a 36% reduction in mortality from CVD compared with the least active third (expending hardly any energy in vigorous activities). However, when men were grouped into thirds of energy expended on light or moderate activities requiring <6 METs, similar rates of CVD mortality were observed in the most and least active thirds of men (expending ⩾343 and ⩽133 kcal/day respectively in light or moderate activities). “If moderate intensity physical activity does not benefit health, should health professionals bother to prescribe such activities? ” This surely comes as bad news for many, as most people living in developed countries are inactive. In the United Kingdom, only 33% of men and 21% of women meet guidelines for physical activity,2 and in the United States, a mere 36% of men and 28% of women engage in regular leisure time physical activity.3 In these largely sedentary societies, persuading those who are inactive to take up moderate intensity physical activity (such as brisk walking) for their health is more likely to meet with success than requiring inactive persons …
Network Analysis on Attitudes

In this article, we provide a brief tutorial on the estimation, analysis, and simulation on attitude networks using the programming language R. We first discuss what a network is and subsequently show how one can estimate a regularized network on typical attitude data. For this, we use open-access data on the attitudes toward Barack Obama during the 2012 American presidential election. Second, we show how one can calculate standard network measures such as community structure, centrality, and connectivity on this estimated attitude network. Third, we show how one can simulate from an estimated attitude network to derive predictions from attitude networks. By this, we highlight that network theory provides a framework for both testing and developing formalized hypotheses on attitudes and related core social psychological constructs.
