Mobile device for detection of biological threat

In the framework of the project SFORA in Military Institute of Chemistry and Radiometry was created a detector for the detection of biological threats. The main achievements of this project are development of a mobile device capable of analyzing the air for the presence of biological contamination and adapt it to work on the unmanned platform. The following presentation will show the results of work on the construction and development of the new type of detector for remote detection of biological hazards. The device is based on the analysis of fluorescence spectra of the sample and then comparing the resulting spectrogram database, which includes the standard curves obtained in the laboratory for selected bacteria. Currently, the device is able to recognize the 7 strains of pathogenic bacteria that can be used as a biological weapon (Bacillus anthracis, Brucella melitensis, Burkholderia mallei, Francisella tularensis, Yersinia pestis, Vibrio cholerae, Clostridium botulinum) and several popular harmless bacteria such as Escherichia coli, Bacillus cereus, etc., but it is possible to extend the list and adapting it for other purposes, eg. The detection of bacteria in hospitals. Samples can be automatically collected from the air or manually introduced into the device as a solution. The measurements provide information about the presence in the sample of bacteria and their approximate concentration. The detector has been designed for military purposes and that why its present form presents the results in three categories: the threat — the detection of pathogenic bacteria present in the database, a potential threat — if it is detected the bacteria, which the spectrogram is not stored in the database, or no risk — in the absence of signal or obtaining a signal from the harmless bacteria present in a database. Because the device is fully automatic, all spectra obtained during the operation are stored in the internal memory, or transmitted to the operator, which can be subjected to additional analysis. The spectra are collected at the different excitation wavelength, and the waveforms are specific for each of the strains. It also takes under analysis the signal intensities of the different spectra (not only shape a maximum of the peak) so it can be determined the concentration of bacteria in the sample under test. The device was tested in the laboratory in the range of concentration from 102 to 106 CFU/mL. The detector can also distinguish between the vegetative forms of spores of the bacteria. The device has a system of pre-concentration, whose main element is a plate coated with a polymeric matrix that allows the subsequent acquisition of trapped bacteria and additional testing in the lab to verify the results.
Electromigration of microbial electron acceptors and nutrients: (II) Transport in groundwater

Bioremediation in contaminated aquifers is often limited by the availability of microbial electron acceptors and nutrients. In this study, electromigration of the electron acceptor nitrate was assessed in sandy model soil mixed with groundwater from a contaminated site, and compared with previous results obtained in soil mixed with demineralized water. The specific nitrate transport rate in soil with groundwater at a voltage gradient of 2 V/cm and 0.5 g/L nitrate was 1.64 cm/h, and proved to be higher than in demineralized water (1.13 cm/h). The application of electrokinetic transport is a promising approach to enhance mass transfer in groundwater systems.
Effets des hautes et très hautes pressions

Actuellement, dans des cellules diamant, des pressions superieures a 10 GPa sont couramment atteintes. Nous entendrons donc par tres hautes pressions celles qui depassent 100 MPa (1 000 bar) ; notons que les relations de cet article s’appliquent des la pression atmospherique. Dans ce domaine, de tres nombreux phenomenes ont ete decouverts et etudies. Des transitions polymorphiques et electroniques ont ete observees comme l’apparition de phases metalliques et parfois supraconductrices a basse temperature. Dans le domaine des syntheses, les developpements les plus importants ont ete la synthese du diamant a partir du graphite et celle du nitrure de bore cubique. Les hautes pressions sont egalement importantes en geophysique et en astrophysique. La Terre et les planetes sont des milieux de tres hautes pressions ou de nombreuses transitions peuvent se produire dans les elements constitutifs. La matiere reagit a l’action de la pression de facon souvent inhabituelle et qu’il faut connaitre, car les dissymetries et les irregularites de forme et de structure peuvent amorcer des reactions dans des pieces soumises a des pressions couramment atteintes. La matiere, qui peut se presenter sous forme liquide ou gazeuse a basse pression, n’existe plus en general que sous forme solide a haute pression. Un metal peut subir une compression assez forte pour que son volume soit reduit de 40 % de sa valeur normale. Une tige pleine d’un metal relativement tendre subit une striction vers la section de moindre resistance et les resultantes longitudinales de la pression peuvent en provoquer la rupture comme cela arrive sur les eprouvettes de traction. Les effets mecaniques exerces par la pression sur une paroi se manifestent souvent sur la face opposee ; un tube se dechire a partir de l’exterieur quand on y comprime un fluide. Comprime vers l’exterieur au contraire (et le cas est particulierement net avec un tube de matiere vitreuse), il se remplit des eclats de sa propre substance. La figure 1 represente le diagramme pression-temperature de l’argon avec ses trois phases gaz-liquide-solide. Nous ne considerons que les proprietes dans les regions hachurees qui correspondent a p > 100 MPa, c’est-a-dire celles qui recouvrent le fluide dense, le solide et la transition fluide-solide. Nous excluons donc les proprietes du gaz dilue et de la region critique. L’unite de pression est le Pascal (Pa) ou le Newton /(metre 2 ) (N /m 2 ), d’autres unites ont egalement ete utilisees dans le passe comme le kilogramme-force/centimetre carre (kgf /cm 2 ), l’atmosphere (atm) ou le bar (bar).

Characteristics of Depressed Caregivers of Veterans With Dementia

This study examined the characteristics of caregivers and persons with dementia (PWD) to determine their association with caregiver depression. Participants included 508 PWD (veterans) and 486 caregivers from Boston, Houston, Providence, Beaumont (Texas), and Oklahoma City, identified from diagnoses from medical records and recruited from February 2007 to July 2009, for a larger study evaluating Partners in Dementia Care, a care-coordination intervention. Characteristics evaluated for PWD included activities of daily living, instrumental activities of daily living, cognitive impairment, and disruptive behavior. Caregiver characteristics evaluated included caregiver unmet needs, support-service use, and number of informal helpers. Caregiver depression was measured using the Iowa form 11-item Center for Epidemiologic Studies Depression Scale. Depressed caregivers reported significantly more unmet needs than the nondepressed caregivers. Depressed caregivers also reported a high frequency of disruptive behavior in their PWD. Caregiver perceptions of unmet needs may be an important target for intervention.
Expression of an Antigenic Adenovirus Epitope in a Group B Coxsackievirus

ABSTRACT Group B coxsackieviruses (CVB) cause human myocarditis, while human adenovirus type 2 (Ad2) is implicated as an agent of this disease. The L1 loop of the Ad2 hexon protein has been demonstrated to be antigenic in rabbits. To evaluate the feasibility of a multivalent vaccine strain against the CVB and Ad2, we cloned the sequence encoding the Ad2 hexon L1 loop, flanked by dissimilar sequences encoding the protease 2A (2Apro) recognition sites, into the genome of an attenuated strain of CVB type 3 (CVB3/0) at the junction of 2Apro and the capsid protein 1D. Progeny virus (CVB3-PL2-Ad2L1) was obtained following transfection of the construct into HeLa cells. Replication of CVB3-PL2-Ad2L1 in diverse cell cultures demonstrated that the yield of the chimeric virus was between 0.5 to 2 log units less than the parental strain. Western blot analyses of the CVB3 capsid protein 1D in CVB3-PL2-Ad2L1-infected HeLa cells demonstrated production of the expected capsid protein. Viral proteins were detected earlier and in approximately fourfold greater amounts in CVB3-PL2-Ad2L1-infected HeLa cells than in CVB3/0-infected cells. Cleavage of the CVB3-PL2-Ad2L1 polyprotein by 2Apro was slowed, accompanied by an accumulation of the fusion 1D-L1 loop protein. Reverse transcription-PCR sequence analysis of CVB3-PL2-Ad2L1 RNA demonstrated that the Ad2 hexon polypeptide coding sequence was maintained in the chimeric viral genome through at least 10 passages in HeLa cells. Mice inoculated with CVB3-PL2-Ad2L1 demonstrated a brief viremia with no replication detectable in the heart but prolonged replication of virus in the pancreas in the absence of pathologic changes in either organ. CVB3-PL2-Ad2L1 induced binding and neutralizing anti-Ad2 antibodies, in addition to antibodies against CVB3 in mice. CVB3-PL2-Ad2L1 was used to challenge mice previously inoculated with CVB3/0 and with preexisting anti-CVB3 neutralizing-antibody titers; anti-Ad2 neutralizing and binding antibodies were induced in these mice at higher levels than in mice without anti-CVB3 immunity. The data demonstrate that a CVB vector can stably express an antigenic polypeptide of Ad2 from within the CVB open reading frame that results in the induction of protective immune responses against both viruses.
The role of matricellular proteins thrombospondin-1 and osteonectin during RPE cell migration in proliferative vitreoretinopathy

Purpose. To investigate the hypothesis that the Matricellular proteins thrombospondin 1 (TSP1), tenascin (TN) and Secreted Protein Acidic and Rich in Cysteine (SPARC) modulate the migration of RPE cells in the epiretinal membranes of proliferative vitreoretinopathy. Methods. Ten PVR epiretinal membranes were studied by immunohistochemical methods in which aggregates of RPE cells were identified by their expression of a broad range of cytokeratins. RPE subsets containing migratory RPE cells were detected by immunoreactivity for the monoclonal antibody RGE53 (which detects an epitope on cytokeratin-18 on motile RPE cells). Co-localisation of the RPE subsets with the glycoproteins TSP-1, SPARC and TN was evaluated. Results. Nineteen migratory RPE (RGE53 positive) subsets and 13 RPE (RGE53 negative) subsets were identified. All of the RGE53+ subsets colocalised with TSP1 and SPARC and 17 with TN. Ten of the RGE53- aggregates stained for TN, 6 for SPARC and 5 for TSP1. The association between the presence of RGE53+ cells in the RPE cell aggregates and TSP1 immunoreactivity in the aggregates was significant (p<0.001), and there was a comparable significant association between RGE53+ cells and SPARC (p<0.001). No such association was detected for RGE53+ cells and TN (p> 0.2). Conclusions. The findings support the concept that the migration of retinal pigment cells in epiretinal membranes is modulated by TSP1 and SPARC and thus that these two proteins ultimately may represent therapeutic targets in the management of the membranes.
Recognition of Gender using Gait Energy Image Projections Based on Random Forest Classifier

Identification of gender is a very fascinating criterion in the present day scenario. Especially, in the surveillance applications, gender recognition is very beneficial. With the use of face, speech, voice and gait, the gender of a person can be determined. Non-contact, non-invasive and easily acquired at distance, gait analysis has attracted the interest of many researchers in the classification of gender. For the identification of gender, 2 stages of the methodology are used in our proposed work. A new descriptor called Gait energy image projection model(GPM) is proposed which highlights all the gender-related parameters. In the second stage of methodology, proposed descriptor GPM is fused with already existing descriptors like GEI and FED for enhanced performance. For classifying the gender, an Ensemble classifier called Random Forests is applied to the individual and fused descriptors and the results are evaluated. Two datasets are used for experimentation namely CASIA B and OU-ISIR datasets which are standard datasets for person identification and different performance metrics such as accuracy, precision, recall and error rate are evaluated.
A study on histological features of lepra reactions in patients attending the Dermatology Department of the Government Medical College, Calicut, Kerala, India.

OBJECTIVES 1. To study and compare the clinical and histological features of Type 1 and Type 2 lepra reactions. 2. To document the histological patterns of Type 1 and Type 2 lepra reactions observed in the study population. DESIGN Two year cross sectional study. Patients attending the outpatient department of our tertiary care hospital, during the 2 year study period with clinical evidence of Type 1 (T1R) or Type 2 (T2R) lepra reactions were included in this study after obtaining written informed consent. During this period 34 T1R patients and 14 T2R patients attended our hospital. Biopsies were taken from reacting skin lesions of all patients and histological features were studied. RESULTS Dermal or intragranuloma oedema was evident in 50% of T1R patients and all of them had clinically severe reactions. The T1R patients showed three different histological patterns--pgrading reactions, downgrading reactions and reactions without upgrading or downgrading. Among T2R patients 8/14 showed neutrophil infiltration histologically, 5/14 showed no histological evidence of neutrophil infiltration and only one patient had features of neutrphilic vasculitis. Dermal oedema was seen in 11/14 cases. CONCLUSIONS Histology revealing dermal or intragranuloma oedema on a background of leprosy granuloma favours the diagnosis of lepra reaction. A careful analysis of subtle variations in the cells constituting the granuloma may aid in differentiating between upgrading T1R, downgrading T1R or T1R without upgrading or downgrading. Histology can also be useful in distinguishing T2R from T1R, in the absence of typical erythema nodosum leprosum (ENL) lesions. Neutrophils are the major inflammatory cells in the former where as lymphocytes or macrophages predominate in the latter. We recommend that histopathological analysis should form an integral part of the evaluation of all lepra reactions.
Electronic speaking system for speech impaired people: Speak up

Sign Language is the only way of communication for speech impaired people. But general people can't understand the sign language so it becomes difficult for a speech impaired person to communicate with them. In this project an electronic speaking system was developed to ease the communication process of speech impaired people. A glove was developed which consists of five flex sensors. When a gesture is made with the glove, the change in resistance of flex sensors fed into the Arduino Nano and specific prerecorded audio command for that gesture is played from SD card through speaker and the text command for that gesture is displayed on the LCD. There are four gestures that are designed for user input so that user can play his/her chosen audio commands using those gestures. This device not only helps a speech impaired person to communicate with a normal person via audio commands but also helps him/her to communicate with a hearing impaired person by displaying the text commands on the LCD.
Upper Limb Disability in Hemodialysis Patients: Evaluation of Contributing Factors Aside From Amyloidosis

This cross‐sectional case‐control study evaluated upper limb muscle strength and shoulder mobility in hemodialysis (HD) patients with arteriovenous fistula or graft. Twenty‐five adult patients on thrice‐a‐week HD treatment for 6 months at least, were selected for the study. In all the patients and control subjects, handgrip tests and tests of range of motion in the upper extremities were evaluated by physiotherapy tests. Patients on HD showed lower muscle strength than age and sex matched subjects without severe chronic kidney disease (right: 30.1 ± 11.6 vs 40.5 ± 15.1 kg, P < 0.001; left 29.1 ± 12.9 vs 40.7 ± 11.1 kg, P < 0.01), and a reduced range of shoulder mobility. The presence of fistula or graft was associated with a greater limitation of both active (74.0 ± 18.3 vs 85.2 ± 8.8 °, P < 0.01) and passive (82.2 ± 9.9 vs 87.2 ± 6.6 °, P < 0.05) extra‐rotation than the contralateral limb, with a higher prevalence of impingement (72 vs 36%, P < 0.05). Muscle strength was related to albumin and inversely to age; whereas β2‐microglobulin and CRP serum levels were associated with impairment of passive and active extra‐rotation of the shoulder that was free from the fistula or graft. In summary, patients on HD have a reduced range of shoulder mobility and marked reduction of muscle strength. The abnormalities are more prevalent in upper limbs with fistula or grafts. The arteriovenous fistula or graft may worsen the disability of the patient's upper limbs presumably due to the obligate position required during the HD sessions. Proper pre‐ and post‐dialysis exercise programs should be implemented to maintain mobility and strength of the upper limbs.
Characterization of polymorphic microsatellite DNA markers in Banksia nivea, formerly Dryandra nivea

A genomic library was constructed and 10 novel polymorphic microsatellite markers were developed for Banksia nivea subsp. uliginosa, a woody shrub endemic to the southwest of Western Australia. Polymorphism was investigated for these markers in 30 individuals from one population located in restricted habitat at the base of the Whicher Range east of Busselton. Expected heterozygosity ranged from 0.124 to 0.898 and averaged 0.570. Observed heterozygosity ranged from 0.133 to 0.933 and averaged 0.544. The number of alleles per locus ranged from 2.0 to 16.0 and averaged 7.3. These markers also produced amplification products in three other Banksia species and will be used to assay genetic diversity in these species.
Behavioral consequences of innate preferences and olfactory learning in hawkmoth–flower interactions

Spatiotemporal variability in floral resources can have ecological and evolutionary consequences for both plants and the pollinators on which they depend. Seldom, however, can patterns of flower abundance and visitation in the field be linked with the behavioral mechanisms that allow floral visitors to persist when a preferred resource is scarce. To explore these mechanisms better, we examined factors controlling floral preference in the hawkmoth Manduca sexta in the semiarid grassland of Arizona. Here, hawkmoths forage primarily on flowers of the bat-adapted agave, Agave palmeri, but shift to the moth-adapted flowers of their larval host plant, Datura wrightii, when these become abundant. Both plants emit similar concentrations of floral odor, but scent composition, nectar, and flower reflectance are distinct between the two species, and A. palmeri flowers provide six times as much chemical energy as flowers of D. wrightii. Behavioral experiments with both naïve and experienced moths revealed that hawkmoths learn to feed from agave flowers through olfactory conditioning but readily switch to D. wrightii flowers, for which they are the primary pollinator, based on an innate odor preference. Behavioral flexibility and the olfactory contrast between flowers permit the hawkmoths to persist within a dynamic environment, while at the same time to function as the major pollinator of one plant species.
A Novel Combine Forecasting Method for Predicting News Update Time

With the rapid development of Internet, information provided by the Internet has shown explosive growth. In the face of massive and constantly updated information on the Internet, how the user can fast access to more valuable and more information has become one of the hot spots. The time of Web Page update appears to be erratic, so forecasting the update time of news reports is even more difficult. From the view of application, we can use mathematical models to maximize the approximation of variation, although it cannot be completely accurate. So is the predicting the update time of news which helps in improving the news crawler’s scheduling policy. In this paper, we proposed a combined predict algorithm for news update. In order to predict the update time of news, firstly, we applied the Exponential Smoothing method to our dataset, and we also have selected the optimal parameters. Secondly, we leveraged the Naive Bayes Model for prediction. Finally, we combined two methods for Combination Forecasting, as well as made a compare with former methods. Through the experiments on Sohu News, we show that Combination Forecasting method outperforms other methods while estimating localized rate of updates.
Design and analysis of double-sided linear primary permanent magnet vernier motor

Linear primary permanent magnet vernier (LPPMV) motor incorporates the merits of high efficiency and low cost because its long stator can be designed as simple iron core only with salient poles. In this paper, a new double-sided linear primary permanent magnet vernier (LPPMV) motor is proposed, which artfully adopts appropriate halbach PM arrays. Compared with the existing single-sided LPPMV motor, the proposed motor has over twice thrust force. Also, the proposed motor exhibits relatively enhanced force performance with various optimized structure elements, which is more suitable for long stoke applications.
Infections with cytomegalovirus and other herpesviruses in 121 liver transplant recipients: transmission by donated organ and the effect of OKT3 antibodies.

One hundred twenty-one adult liver transplant recipients were studied for the incidence, risk factors, and morbidity associated with herpesviruses infections after transplantation. The overall incidence of infection was 59% for cytomegalovirus (CMV), 35% for herpes simplex virus (HSV), 25% for Epstein-Barr virus (EBV), and 7% for varicella-zoster virus (VZV). Primary CMV infection occurred in 46% and reactivation CMV infection in 67% of the susceptible recipients. Symptomatic and disseminated CMV diseases were more common when patients developed primary infection (P less than .01, for both comparisons). The donor organ appeared to be the only important source of CMV infection in seronegative recipients. The use of OKT3 antibodies was associated with disseminated CMV disease in patients with primary infection (P = .04) but not with reactivation infection (P greater than .10). Although most HSV infections were oral or genital reactivations, three cases of HSV hepatitis occurred--one was a primary infection. Symptomatic reactivations of HSV were observed in 53% of HSV-seropositive recipients who received OKT3, versus 31% of seropositive recipients who did not receive OKT3 (P = .05).
