Fabrication of silicon nanoplate and nanowire biosensor arrays with high specificity and sub-picomolar limits of detection

Diagnostic platforms based upon microfluidics coupled to ion-selective field effect transistors (ISFET’s) offer great potential to address some world health goals since they can be made portable, low-cost, miniaturized, and sensitive. We have fabricated arrays of accumulation mode, fully depleted silicon nanowires (50 nm width) and nanoplates (2um width) of 30nm thickness on SOI substrates, all of which are individually addressable. The devices respond to changes in charge density well and have excellent time stability in fluid. By coupling probe proteins to the ISFET surface, we are able to detect analytes down to pg/mL levels.
Internet of Satellites (IoSat): an interconnected space paradigm

During the last years the space has been populated by Distributed Satellite Systems, which some of them have started to implement Inter-Satellite Communication. However, current solutions are composed of a unique mission and homogeneous spacecrafts or a combination of them. This actually limits their use in the so-called “Federated Satellite Systems” that proposes the interconnection of heterogeneous spacecrafts in order to establish a mission collaboration whenever the resources are not used for the primary mission goal. This point-to-point proposal has some limitations that can be addressed in a multi-hop platform, i.e. a network. Current satellite network proposals, such as Space Internet or Heterogeneous Spacecraft Network, propose the creation of a common network backbone which provides connectivity for future missions. However, this approach supposes huge maintenance and deployment costs. This work presents a new interconnected space paradigm based on a more peer-to-peer architecture: Internet of Satellites. This new paradigm promotes the creation of sporadic networks, called Inter Satellite Networks, which provide the required communication means to deploy Federated Satellite Systems for multi-hop cases.
Theoretical Analysis of Effects of Wall Suction on Entropy Generation Rate in Laminar Condensate Layer on Horizontal Tube

The effects of wall suction on the entropy generation rate in a two-dimensional steady film condensation flow on a horizontal tube are investigated theoretically. In analyzing the liquid flow, the effects of both the gravitational force and the viscous force are taken into account. In addition, a film thickness reduction ratio, , is introduced to evaluate the effect of wall suction on the thickness of the condensate layer. The analytical results show that, the entropy generation rate depends on the Jakob number Ja, the Rayleigh number Ra, the Brinkman number Br, the dimensionless temperature difference , and the wall suction parameter . In addition, it is shown that in the absence of wall suction, a closed-form correlation for the Nusselt number can be derived. Finally, it is shown that the dimensionless entropy generation due to heat transfer, , increases with an increasing suction parameter , whereas the dimensionless entropy generation due to liquid film flow friction, , decreases.
The Efficacy and Effectiveness of Online CBT

In 1997, researches at the University of Amsterdam developed one of the first psychotherapeutic applications of the World Wide Web. The implemented a standardized cognitive behavioural treatment (CBT) of post-traumatic stress symptoms in a website, and used this site to treat clients over the internet, without face-to-face contact. Over the years, the efficacy of this treatment was established in a series of controlled trials. In this dissertation, we explore the wider applicability of online CBT, in four randomized controlled trials and a practice study. In the controlled studies, we assess the efficacy of online CBT for work-related stress, mild to moderate depression, panic disorder and bulimia nervosa. In the fifth study, we examine the effectiveness of online CBT in routine clinical practice. The results suggest that online CBT provided a feasible alternative to existing treatment options for people who suffer from a variety of mental health disorders.
Thermal Management with Asymmetric Dual Core Designs ; CU-CS-965-03

Thermal considerations play an increasingly important role in the design of new processors. Thermal concerns impact how chips are laid out, how quickly processors can be clocked, processor reliability, and how expensive the packaging is. Current production chips are often packaged to dissipate maximum typical power, rather than maximum absolute power. We investigate techniques which would allow the use of an even lower thermal threshold, thus further reducing packaging costs. We examine single core and dual core solutions to deal with thermal overloads. Our single core solutions include techniques already deployed by chip manufacturers and others proposed by researchers. We also present symmetric and asymmetric dual core techniques. We find that our dual core techniques compare favorably to single core techniques in their ability to reduce thermal loads. Our asymmetric dual core techniques provide additional advantages over single core techniques, by providing an additional low power core that can be used to improve overall system throughput.
Phenolic Contents and Antioxidant Potential of Crataegus Fruits Grown in Tunisia as Determined by DPPH, FRAP, and β-Carotene/Linoleic Acid Assay

Crataegus fruit is one of most important fruits in Tunisian flora. Some fruits of this genus are edible. This study was undertaken in order to examine the benefits of these fruits in human health and their composition of antioxidants including total polyphenol, flavonoids, proanthocyanidins content, and total anthocyanins. The antioxidative properties of the ultrasonic methanolic extract were assessed by different in vitro methods such as the FRAP, DPPH, and β-carotene/linoleic acid assay. We concluded that peel fraction of red fruits possessed relatively high antioxidant activity and might be a rich source of natural antioxidants in comparison with the pulp and seed fruit extract. The results also showed that hawthorn yellow fruit presents lower amounts of phenolic content, absence of anthocyanins, and less antioxidant capacity. Most of peel and seed fractions were stronger than the pulp fractions in antioxidant activity based on their DPPH IC50, FRAP values, and results of β-carotene/linoleic acid. The total phenolic compounds contents were also highly correlated with the DPPH method and the FRAP assay.
EFFECT OF CATHODAL TRANSCRANIAL DIRECT CURRENT STIMULATION ON LOWER LIMBS MUSCULAR FATIGUE DURING ISOKINETIC PROTOCOL

The objective of this study was to evaluate the relations between tDCS by cathodal current and a fatigue indicator in lower limb during isokinetic protocol. In this study was evaluated the results obtained on assessment of isokinetic force of knee extensors and flexors, in concentric muscular action during flexion and extension phases. Seven health volunteers (6 men and 1 woman) participated in the study. The results show significant differences between sham and cathodal conditions only for work/body weight and work fatigue during knee flexion phase. Cathodal tDCS appear to be a valid technique to modulated primary motor cortex activity. The preliminary results suggest that cathodal current polarization appears to be a helpful tool to improve work capacity in human subjects, at least for knee flexion.
Hive temperatures for each hour of a day

Of the climatic factors in the environment of the honey-bee, temperature modifies their reactions more than any other factor. The well known clustering of bees during the winter and the period of normal brooding of honeybees are two distinct physiological conditions within the colony, brought about by the one environmental factor, temperature. The former condition has been the subject of a great deal of experimental work and has been worked out rather thoroughly. On the other hand, investigations on the latter condition have been more or less limited. This study on the temperatures within the colony was carried on during the summer of 1926. I wish to express my appreciation to Professor W. M. Barrows for his helpful suggestions and encouragement in many phases of the work; to Dr. E. F. Phillips, Cornell University, for loaning German beekeeping literature pertaining to hive temperatures, and to Mr. Morris Schlosberg, for his help in constructing the compound thermocouple.
Globalisasi Peluang atau Ancaman bagi Indonesia

Dalam Beberapa dekade belakangan, globalisasi dan regioanalisasi ekonomi telah menjadi salah satu isu menarik di luar isu-isu lain seperti isu-isu tentang keamanan dan lingkungan global. Sebagai isu yang paling sering dibahas, globalisasi menjadi sebuah fenomena multifaset yang menimbulkan beraneka ragam praduga dan interpretasi.
Identity-Based Policies and Identity Manipulation: Evidence from Colonial Punjab

I study identity-marker based policies and demonstrate the existence of identity manipulation. I analyze the impact of the Punjab Alienation of Land Act (1901), a caste-based legislation, on identity manipulation. Using data from the colonial census, I show that a movement of identity manipulation took place in response to the law. I estimate that in 20 years, 7.5 percent of the population that had an incentive to do so manipulated its identity. I then use an accounting exercise to estimate that the amount of mistargeting caused by this manipulation is between 3.9 percent and 8.2 percent of the land distributed.

Experiences with Gin Process Control in the Midsouth and West

Various components of a computerized process control system, such as infrared moisture meters, video cameras, computers, paddle samplers, pneumatic cylinders, etc., were installed in a phased approach over a five-year period at two commercial cotton gins. The systems are not yet fully automated or fully implemented, but all of the components that have been evaluated functioned well for extended periods of time. Analyses indicate that reducing the number of lint cleaners from two to one on cotton selected by the computerized system could increase the bale value by about $3 to $6 each. Controlling moisture correctly could have a similar impact and a savings of about $6 per bale. Total additional profits for cotton grown in the United States could exceed $135 million annually.
A Robust General Equilibrium Stochastic Volatility Model with Recursive Preference Investors

This paper investigates the implications of model uncertainty for the equity premium in a stochastic volatility model. We consider a general equilibrium setting with one representative agent who has a stochastic differential utility. The results show that the equilibrium equity premium consists of a market risk premium, a stochastic volatility risk premium and an uncertainty aversion premium. Further, the robustness can increase the equilibrium equity premium and drive down the equilibrium risk-free rate.
Discourse moves and intercultural communicative competence in telecollaborative chats

With a shift toward understanding the goals of foreign language learning as development of intercultural communicative competence (ICC; Thorne, 2010), telecollaborative interaction with geographically distant partners has been seen both as a pedagogical tool that can play a significant role in promoting intercultural negotiation abilities and attitudes and as a felicitous context for assessing these abilities. Addressing the assessment task through a linguistically-grounded investigation of telecollaborative chats, this exploratory study aims to demonstrate how abstract aspects of ICC can be operationalized as deployment of particular discourse structuring and linguistic resources. Drawing on the systemic-functional approach to discourse analysis (Eggins & Slade, 1997) and Byram’s (1997) framework of ICC, this study examines written synchronous chats created throughout a 7-week telecollaborative activity by advanced American learners of German at a private US University and by German University students, future FL teachers. The quantitative and qualitative results demonstrate what precise discursive moves and language resources that realize them characterize ICC and at the same time enable it. Implications of the use of the methodological framework for further research of ICC in telecollaborative discourse, as well as some applications of the findings to pedagogy, conclude the study.

Microstructure and Mechanical Properties of ADI Depending on Austenitization Methods and Parameters

Ductile iron was quenched using two-variant isothermal transformation. The first treatment variant consisted of one-phase austenitization at a temperature t = 830, 860 or 900 C, cooling down to an isothermal transformation temperature of 300 or 400 C and holding from 8 to 64 minutes. The second treatment variant consisted of two-phase austenitization. Cast iron was austenitizied at a temperature t = 950 C and cooled down to a supercritical temperature t ’ = 900, 860 or 830 C. Isothermal transformation was conducted under the same conditions as those applied to the first variant. Ferrite cast iron was quenched isothermally. Basic strength (Rp0.2, Rm) and plastic (A5) properties as well as matrix microstructure and hardness were examined. As a result of heat treatment, the following ADI grades were obtained: EN-GJS-800-8, EN-GJS-1200-2 and EN-GJS-1400-1 in accordance with PN–EN 1564:2000 having plasticity of 1.5÷4 times more than minimum requirements specified in the standard.
Production of ethanol from tuberous plant (sweet potato) using Saccharomyces cerevisiae MTCC-170

The aim of this work was to research a bioprocess for bioethanol production at laboratory scale from raw sweet potato using Saccharomyces cerevisiae MTCC-170. In order to obtain maximum conversion of starch into fermentable sugar, optimum parameters for the liquefaction were determined as 104 to 105°C, 0.15% v/w of α-amylase enzyme solution (300 U/ml) and 30 g dry-weight sweet potato mash/100 ml distilled water, respectively with a 74.38% loss in dry weight during the process. For saccharification process, the optimum dose of amyloglucosidase was 0.25% v/w (300 U/ml) with 16.82% glucose production at pH 5.0 and temperature 60°C after 1 h. The fermentation parameters like inoculum size, temperature, pH and different concentrations of nutrients were also determined. The maximum ethanol concentration, that is, 7.95% (v/v) was obtained with 10% inoculum size at pH 6.0 after 48 h. Furthermore, out of the three nitrogen sources (yeast extract, peptone and ammonium sulphate) tested for ethanol production, peptone at a concentration of 1.5 g/L was found to be best (7.93%). From the present study, it may be concluded that sweet potato can be an attractive feedstock for bioethanol production from both the economic stand points and environment friendly.

Seasonal variations in concentration and lability of dissolved organic carbon in Tokyo Bay

Abstract. Concentrations of recalcitrant and bioavailable dissolved organic carbon (DOC) and their seasonal variations were investigated at three stations in Tokyo Bay, Japan, and in two freshwater sources flowing into the bay. On average, recalcitrant DOC (RDOC), as a remnant of DOC after 150 days of bottle incubation, accounted for 78% of the total DOC in Shibaura sewage treatment plant (STP) effluent, 67% in the upper Arakawa River water, 66% in the lower Arakawa River water, and 78% in surface bay water. Bioavailable DOC (BDOC) concentrations, defined as DOC minus RDOC, were lower than RDOC at all stations. In freshwater environments, RDOC concentrations were almost constant throughout the year. In the bay, RDOC was higher during spring and summer than in autumn and winter because of freshwater input and biological production. The relative concentration of RDOC in the bay derived from phytoplankton, terrestrial, and open-oceanic waters was estimated to be 8–10, 21–32, and 59–69%, respectively, based on multiple regression analysis of RDOC, salinity, and chl a. In addition, comparison with previous data from 1972 revealed that concentrations of RDOC and BDOC have decreased by 33 and 74% at freshwater sites and 39 and 76% in Tokyo Bay, while the ratio of RDOC to DOC has increased. The change in DOC concentration and composition was probably due to increased amounts of STP effluent entering the system. Tokyo Bay exported mostly RDOC to the open ocean because of the remineralization of BDOC.
A Coupled-Fed Reconfigurable Antenna for Internal LTE Mobile Phone Applications

In this paper, a multi-frequency broadband planar reconfigurable antenna is designed for smart mobile phone applications. The antenna comprises two monopole strips and a parasitic shorting strip, and generates several independent resonant modes through this kind of stub loading. The miniaturization and broadbandization of the antenna is achieved by bending the strip line and using coupling feed. In addition, loading the matching circuit at the feeding point, the bandwidth can completely cover 824–960 and 1710–2690 MHz. In order to cover a lower band LTE band 20 (800 MHz), an RF switch at shorting point is used to switch low frequency to 791 MHz. So the proposed antenna can work at GSM850, 900; DCS1800; PCS1900; WCDMA bands 1, 2, 4, 5, 8; TD-SCDMA bands A, F; CDMA BC0, BC1 and LTE bands 1, 3, 5, 7, 8, 20, 38, 39, 40, 41. Also, the total size of the antenna is 15mm × 30mm × 0.8 mm, which is very suitable for 4G slim smart mobile phone applications.

Absorbing Sets of Generalized LDPC Codes

In this paper we propose a definition of Absorbing Sets for binary Generalized LDPC (GLDPC) codes. We show that under practical Max-Log iterative decoding, our AS definition enables a local description of the message evolution with the iterations, with a simplified model very similar to the one used for the analysis of Min-Sum LDPC decoding. Accordingly, these ASs exhibit a threshold behavior also in GLDPC codes.
Hemodynamic Catheters: The Reprocessing, Cleanliness and in vitro Biofilm Formation by Enterococcus faecium in a Continuous Flow Model

Reprocessing single-use devices to cut costs is a common practice in hospitals around the world. In Brazil, there are few studies of reprocessing hemodynamic catheters and thus, this study aimed to evaluate the effectiveness of reprocessing hemodynamic catheters before and after biofilm formation in vitro using a continuous flow model. We used a sterility test and Scanning Electron Microscopy (SEM) to assess the presence of microorganisms, residue and integrity of a New (NC) and Reprocessed (RC) hemodynamic catheter, before and after in vitro biofilm formation by a clinical isolate of Enterococcus faecium (strain 155). NC was considered the negative control. The sterility test did not show the presence of microorganisms in either catheters used as a negative control (NC and RC). On the other hand, changes in integrity were observed by SEM in the RC, with a large number of microcracks and recesses, indicating that this would get worse after reprocessing. After biofilm formation and subsequent sterilization by ethylene oxide, both catheters were examined by SEM and RC showed a dense array of exopolysaccharide and substantial organic waste material, which was not evident in NC, showing changes in surface integrity. Ethylene oxide sterilization is very efficient in the sterilization process but the reprocessed catheters after biofilm formation by strain 155, showed marked surface changes, which increases the adhesion of organic matter and compromises the cleaning process in reprocessing. The results can be used as a parameter for hospitals and companies that reprocess catheters, to develop protocols for standardized and systematic surveillance in reusing materials recommended for single use to prevent infections.
Biogeosciences Mesoscale modelling of the CO 2 interactions between the surface and the atmosphere applied to the April 2007 CERES field experiment

This paper describes a numerical interpretation of the April 2007, CarboEurope Regional Experiment Strategy (CERES) campaign, devoted to the study of the CO 2 cycle at the regional scale. Four consecutive clear sky days with intensive observations of CO 2 concentration, fluxes at the surface and in the boundary layer have been simulated with the Meso-NH mesoscale model, coupled to ISBA-A-gs land surface model. The main result of this paper is to show how aircraft observations of CO 2 concentration have been used to identify surface model errors and to calibrate the CO 2 driving component of the surface model. In fact, the comparisons between modelled and observed CO 2 concentrations within the Atmospheric Boundary Layer (ABL) allow to calibrate and correct not only the parameterization of respired CO 2 fluxes by the ecosystem but also the Leaf Area Index (LAI) of the dominating land cover. After this calibration, the paper describes systematic comparisons of the model outputs with numerous data collected during the CERES campaign, in April 2007. For instance, the originality of this paper is the spatial integration of the comparisons. In fact, the aircraft observations of CO 2 concentration and fluxes and energy fluxes are used for the model validation from the local Correspondence to: C. Sarrat (claire.sarrat@cnrm.meteo.fr) to the regional scale. As a conclusion, the CO 2 budgeting approach from the mesoscale model shows that the winter croplands are assimilating more CO 2 than the pine forest, at this stage of the year and this case study.
