Effects of seed priming with Plant Growth Promoting Rhizobacteria (PGPR) on yield and yield attribute of maize (Zea mays L.) hybrids (2011)

In order to evaluate the effects of seed priming with Plant Growth Promoting Rhizobacteria (PGPR) on dry matter remobilization and yield of maize (Zea mays L.) hybrids, a factorial experiment based on randomized complete block design with three replications was conducted in 2009 at the Research Farm of the Faculty of Agriculture University of Mohaghegh Ardabili. Factors included seed priming of maize hybrids (SC-404, SC-410 and SC-434) with PGPR in three levels: Without priming (as control), priming with Azotobacter or Azospirillum and Azotobacter+Azospirillum. The results showed that seed priming with PGPR affected grain yield, plant height, number of kernels per ear and number of grains per ear row significantly. Maximum of these characteristics were obtained by the plots, which seeds were inoculated with Azotobacter bacteria. Mean comparison of treatment combination corn hybrid×priming with PGPR showed that maximum grain yield and number of kernels per ear were obtained by the plots of SC-434 with Azotobacter and in SC-404 hybrid without seed priming. Investigation of process of variances of dry matter accumulation indicated that in all of hybrids, it increased slowly until 36 days after sowing and then increased rapidly until 116 days after sowing and from 116 days after sowing until harvest time; it decreased due to increasing aging of leaves. In addition, in all of maize hybrids, dry matter accumulation in unit of area increased with seed priming with Azotobacter. The highest grain yield (7.01 ton/ha) and dry matter accumulation (2019 g/m 2 ) was obtained in treatment compound SC-434 maize hybrid at seed priming with Azotobacter. Thus, it can be suggested that SC-434 hybrid should be inoculated with Azotobacter bacteria in conditions of Ardabil Plain.
An inexpensive automatic device for maintaining the level of liquid nitrogen in cold traps (1973)

An automatic device is described for maintaining the level of liquid nitrogen in cold traps fitted to vapour diffusion pumps, in which an air 'thermometer' is used as a level sensor.
Secretory leukocyte protease inhibitor (SLPI) in mucosal fluids inhibits HIV‐1 (1997)

Despite the presence of HIV-1 in the oral cavity, transmission of the virus through saliva has not been proven. Consistent with these observations, we recently identified an endogenous 12 kD protein, secretory leukocyte protease inhibitor (SLPI), in saliva which blocks HIV-1 infection in vitro. Whereas other salivary proteins tested were inactive, purified native or recombinant SLPI inhibited HIV-1 infection of human monocytes at 100 ng ml-1. Levels of SLPI quantitated by ELISA in saliva from control and HIV-1 infected individuals exceeded this level, consistent with in vivo antiviral activity. As in saliva, levels of SLPI mRNA determined by Northern hybridization, and protein as assessed by immunohistochemistry in the salivary glands of control and infected populations were comparable. In contrast to adults, oral transmission occurs in infants, possibly due to their lack of fully developed salivary glands. To determine whether the inadequate antiviral protection might be compensated for by maternal sources, we evaluated breast milk samples obtained 6 months postpartum. Levels of SLPI were significantly lower than in saliva and not sufficient to provide antiviral protection in contrast to colostrum samples in which SLPI levels were equivalent to those in saliva and able to inhibit HIV-1 infection when tested in vitro. These data suggest that breast milk may provide transient antiviral activity in the newborn, but that this maternal source of SLPI is of insufficient duration to maintain protection against mucosal transmission of the virus over time. The high functional levels of SLPI in saliva and the low levels in mature breast milk correlate with negligible rates of HIV-1 transmission by saliva and higher rates by breast feeding.

Integrating Immunobased Detection and Identification Methods for Ricin Analysis: An Overview (2011)

Ricin is one of the most potent naturally occuring toxins and is among the deadliest poisons available. It gained fame by its use in the so-called ‘umbrella murder’ to kill the Bulgarian dissident Georgi Markov in 1978. Ricin is considered as a potential bioterrorism agent due to its toxicity, easy availability of raw materials, inexpensive and simple production of large quantities, and an extensive history of use as a bioweapon. In addition, ricin is soluble in water and stable under heat and a wide pH range. Therefore, there is a potential for ricin to be intentionally added into food or water. For environmental detection in bioterrorism attack as well as for medical treatment purpose, there is a need for a rapid and sensitive detection and quantitation method on trace amount of ricin. This review gives an overview of the different detection methods available for ricin-a biothreat agent. The aim of this review is to give an overall picture of the past and present trend in the detection methodologies and to integrate them for ricin analysis. The objective of this paper is focused on the detection of ricin that might be used as a biological weapon.
Dynamic Role and Context-Based Access Control for Grid Applications (2005)

Despite the recent advances in access control approaches applicable to grid computing, there remain issues that impede the development of effective access control for grid applications. Amongst them are the lack of context-based models for access control, and reliance on identity or capability-based access control schemes. In this paper, we propose RCBAC model which extends the RBAC with context constraints. The RCBAC mechanisms dynamically grant and adapt permissions to users based on a set of contextual information collected from the grid environments, while retaining the advantages of RBAC model.
A pilot study of vertical flow wetlands at coffs harbour, New South Wales, Australia (1995)

A modular series of vertical flow wetland (VFW) systems was established in 1989/90 to treat up to 130,000 litres per day of primary settled sewage on the north coast of New South Wales, Australia as an experimental scale-up of wetland microcosms that had been developed with this hydrological format. Monitoring of inflow and outflow water quality was maintained on a weekly basis from January 1991 to February 1992. Some management parameters (e.g. flow rates) were varied during this period. Dye injection to examine hydraulic behaviour within the gravel bed was carried out on two occasions in one VFW. In general the removal of nutrients was lower than expected, with between 20% and 40% reduction in concentrations and removal of loads over the year. Suspended solids and BOD removals were excellent, with a surprisingly good reduction in faecal coliform counts as well. Reduction in flow rates improved performance markedly in all parameters.
Diffusional enhancement of holograms: phenanthrenequinone in polycarbonate (2002)

As a further development of the manufacture of holographic gratings by the diffusion of phenanthrenequinone in polymer glass, the traditionally employed poly(methyl methacrylate) is replaced by poly(bisphenol-A-carbonate). The post-exposure growth and decay of the gratings in the two materials are compared at different spatial periods and temperatures. The medium with polycarbonate demonstrates a fortunate combination of significantly improved stability of the gratings and their faster development. Our results indicate that the polycarbonate materials promise to be suitable media for holographic optical elements and data storage.

Densitometry of an Embossed Kinescope Recording Film (1956)

The requirements for image analysis of Eastman Embossed Kinescope Recording Film, Type 5209, are discussed. The actual distribution of density of the embossed film image is shown. The optical requirements necessary to analyze these images are similar to those used in projection. It is further shown that these requirements can be made by a comparatively simple modification of a Westrex Densitometer. The results of sensitometric evaluation of satisfactory color images measured on this modified instrument are shown.
Sleep disturbance in post‐traumatic stress disorder: A comparison with non‐PTSD insomnia (1990)

Abstract Sleep disturbances, including repetitive nightmares and insomnia, are central and long‐lasting aspects of Post‐Traumatic Stress Disorder (PTSD). This study utilized a questionnaire to compare sleep disturbance in Vietnam War combat veterans having PTSD with non‐PTSD patients having insomnia without other PTSD symptoms. The PTSD group reported symptoms of anxiety, agitation and concurrent body movement which were associated with insomnia. Nightmares of this group were more repetitive and more disruptive of a return to sleep than the non‐PTSD insomnia group. The PTSD group also reported more fatigue during daytime functioning and more anxiety during waking hours than the non‐PTSD insomnia group.
Measurement reduction for mutual coupling calibration in DOA estimation (2012)

Mutual coupling is an important source of error in antenna arrays that should be compensated for super resolution direction‐of‐arrival (DOA) algorithms, such as Multiple Signal Classification (MUSIC) algorithm. A crucial step in array calibration is the determination of the mutual coupling coefficients for the antenna array. In this paper, a system theoretic approach is presented for the mutual coupling characterization of antenna arrays. The comprehension and implementation of this approach is simple leading to further advantages in calibration measurement reduction. In this context, a measurement reduction method for antenna arrays with omni‐directional and identical elements is proposed which is based on the symmetry planes in the array geometry. The proposed method significantly decreases the number of measurements during the calibration process. This method is evaluated using different array types whose responses and the mutual coupling characteristics are obtained through numerical electromagnetic simulations. It is shown that a single calibration measurement is sufficient for uniform circular arrays. Certain important and interesting characteristics observed during the experiments are outlined.
Comparison of Least Squares and Minimum Variance Estimates of Regression Parameters (1962)

The basic problem dealt with here is the estimation of linear regression parameters from a set of observations obscured by correlated noise. Two well-known solutions to this problem are minimum variance (or Markov, MV) and least squares (LS) estimation. Although MV is, by definition, an optimal method, LS possesses two distinct advantages which cause it to be used more frequently in practice: (1) computational simplicity and (2) the fact that it does not require knowledge of the correlation matrix of the noise, which in many cases is actually unknown. Therefore, a comparative study of these two methods to determine how much is lost by use of LS instead of MV is of value. In this connection, Grenander and Rosenblatt [1] have derived important asymptotic properties of LS and MV estimates when the noise is a stationary random process. The approach here is somewhat different from theirs, and no assumption regarding stationarity is made. The essence of this analysis is to re-formulate LS and MV in terms of the spectrum of the noise correlation matrix. This procedure offers some new insights into the nature of LS and MV and the differences between them. For example, it shows when they yield the same result and when LS performs worst compared with MV. It also exhibits the roles played by the maximum and minimum eigenvalues of the noise correlation matrix in setting bounds on the covariance matrices of both LS and MV estimates.
Über das Reaktionsgleichgewicht Si + SiCl<sub>4</sub> = 2 SiCl<sub>2</sub> und die thermochemischen Eigenschaften des gasförmigen Silicium(II)‐chlorids (1953)

Abstract Silicium(IV)‐chlorid reagiert bei höherer Temperatur mit Silicium unter Bildung von gasförmigem Silicium(II)‐chlorid. Dies wurde aus statischen Gleichgewichtsmessungen (zwischen 1125 und 1300° C) abgeleitet. Auf die Normaltemperatur von 298° K bezogen, ergibt sich für die Reaktion die Reaktionswärme zu 83,2 kcal und die Reaktionsentropie zu 58,5 cl. Die Bildungswärme für SiCl 2 gas beträgt bei 298° K 29,9 kcal und die Normalentropie 71,1 cl.
Compatible osmolytes modulate the response of porcine endothelial cells to hypertonicity and protect them from apoptosis (2002)

Porcine pulmonary arterial endothelial cells accumulated myo-inositol and taurine, as well as betaine, during adaptation to hypertonic stress. The cells grew and maintained their normal morphology during culture in hypertonic (0.5 osmol (kg H(2)O)(-1)) medium that contained osmolytes such as betaine, myo-inositol or taurine at concentrations close to reported physiological values. The cells did not grow well in hypertonic medium depleted of potential compatible osmolytes. After a few days, cell density decreased by about 50 % and many cells rounded up and detached from the plates, their nuclei showing clear apoptotic morphology. The caspase-3 activity of the cells also increased dramatically under these conditions, but remained negligibly low when betaine and myo-inositol were added to the medium. Addition of betaine and myo-inositol to hypertonic medium depleted of compatible osmolytes increased the number of colonies remaining after 12 days of culture; with each solute at 30-100 micromol l(-1) the number increased about sixfold. In the absence of compatible osmolytes, increased mRNA levels and corresponding activities of betaine/gamma-aminobutyric acid transporter (BGT1) and sodium/myo-inositol transporter (SMIT) induced by hypertonicity remained high after 72 h incubation, whereas they were down regulated in the presence of betaine and myo-inositol. Similarly, the down regulation of the amino acid System A transporter (ATA2) was markedly slowed in the absence of compatible osmolytes. We conclude that these compatible osmolytes at concentrations close to physiological values enable the endothelial cells to adapt to hypertonic stress, protecting them from apoptosis, and also modulate the adaptation process.
<title>Formula for the contrast sensitivity of the human eye</title> (2003)

For design criteria of displayed images and for the judgment of image quality, it is very important to dispose of a trustful formula for the contrast sensitivity of the human eye. The contrast sensitivity function or CSF depends on a number of conditions. Most important are the luminance and the viewing angle of the object, but surround illumination can also play a role. In the paper a practical formula is given for a standard observer. This formula is derived from a more general physical formula for the contrast sensitivity. In this paper also the effects of orientation angle and surround luminance will be treated. The orientation angle will be incorporated in the formula and a correction factor will be given for the dependence on surround luminance.
Dynamic Properties of Temperature-Sensitive Poly(<i>N</i>-isopropylacrylamide) Gel Cross-Linked through Siloxane Linkage (2000)

A gel is a water-insoluble polymeric material though it can absorb a lot of water in its network structure. The poly(N-isopropylacrylamide) (PNIPA) gel exhibits a change in volume in response to external temperature changes and this property is useful in many fields. In this manuscript, a novel PNIPA gel was synthesized by using ethylene triethoxy silane (ETEOS) as the cross-linking agent under acidic conditions. This siloxane incorporated PNIPA gel achieves a dramatically rapid response rate when the external temperature is changed. We suggest that the improvement of the response rate could be due to the macroporous structure of the produced polymer network during the polymerization/cross-linking process. This macroporous structure can provide interconnected water release channels and prevent the formation of a dense, thick skin layer at the shrinking course. On the other hand, water can also diffuse into the polymer network through these water channels during the reswelling process.
An Evaluation of Ten Pairwise Multiple Comparison Procedures by Monte Carlo Methods (1973)

Abstract Computer simulation techniques were used to study the Type I and Type III error rates and the correct decision rates for ten pairwise multiple comparison procedures. Results indicated that Scheffé's test, Tukey's test, and the Student-Newman-Keuls test are less appropriate than either the least significant difference with the restriction that the analysis of variance F value be significant at α = .05, two Bayesian modifications of the least significant difference, or Duncan's multiple range test. Because of its ease of application, many researchers may prefer the restricted least significant difference.

The Effect of Gate Length on SOI-MOSFETs Operation (2010)

The effect of gate length on the operation of silicon-on-insulator (SOI) MOSFET structure with a layer of buried silicon oxide added to isolate the device body has been simulated. Three transistors with gate lengths of 100, 200 and 500 nm are simulated. Simulations show that with a fixed channel length, when the gate length is increased, the output drain current characteristics slope is increased, and therefore the transistor transconductance increases. Moreover, with increasing the gate length, the effect of the drain voltage on the drain current is reduced, which results in the reduced drain induced barrier lowering.
Scheduling algorithm for real-time VBR video streams using weighted switch deficit round robin (2003)

The paper presents a modified version of the deficit round-robin (DRR) scheduling algorithm due to [M. Shreedha et al., June 1996]. The proposed scheduling scheme called weighted switch deficit round robin (WSDRR) categorises the different frame types of compressed video which are handled in separate queues and prioritizes time-sensitive and visually important data. WSDRR also introduces an overdraft threshold that basically allows a packet to be scheduled even if its flow's deficit is not large enough in a given scheduling round. By numerical experiments, WSDRR achieves better delay and delay jitter performance than DRR scheduling algorithm. Hence the delay, jitter can further meet requirement for real-time VBR video transmission.
Protein Folding in Hydrophobic-Polar Lattice Model: A Flexible Ant-Colony Optimization Approach (2008)

This paper proposes a flexible ant colony (FAC) algorithm for solving protein folding problems based on the hydrophobic-polar square lattice model. Collaborations of novel pheromone and heuristic strategies in the proposed algorithm make it more effective in predicting structures of proteins compared with other state-of-the-art algorithms.
Corner Point Singularity of 3-D crack subjected to Mode II loading (2000)

The point where the front of a 3-D crack intersects a free surface is called "corner point". The ordinary crack tip stress singularity of r^λ with λ=-0.5 has been well known in fracture mechanics. However, with regard to the stress singularity at the corner point there are several theories which have not been clearly accepted. This paper is concerned with the detailed analysis of the stress singularity at the corner point for a through crack and a semi-circular crack under Mode II loading. According to the theories by Benthem and others, not only K_<II> but also K_<III> has a non-zero value at a corner point which, however, contradicts the stress free boundary condition of free surface. The FEM analysis of the present study based on the careful meshing and accurate determination of singularity (λ) has revealed that although the value of K_<III> increases as the crack front approaches the comer point, the domain of non-zero value of K_<III> decreases infinitesimally and accordingly the influence of K_<III> can be ignored at the corner point. Similarly, the domain of the singular stress field with λ≐̸-0.5 and λ=-0.6∿-0.5 also decreases as the crack front approaches the corner point.
On the Crystal Structures and Electrolytic Conditions of Chromium Electrodeposits (1972)

The electrodeposition from chromic acid solutions has been investigated under various conditions. The results obtained are as follows:(1) The depositions with hcp and fcc types tend to deposit under the following conditions; (i) high concentration of chromic acid in the bath, (ii) low temperature of the bath, (iii) high current density and (iv) the use of pulsating direct current. The effects of addition agents which may reduce the trivalent chromium are not essential to form these deposits.(2) Both the hcp and fcc type deposits are chromium hydride CrHx(x\simeq1) but not CrH2 which was reported by Snavely for the fcc type deposits.(3) The current efficiency for the hcp type deposits is 27∼37% and that for the fcc type deposits is 7∼13%.(4) The lattice constant of the hcp type deposits is a=2.722±0.003 Å, c⁄a=1.629±0.01 and that of the fcc type is a=3.8585±0.0003 Å. However, the lattice constant of bcc chromium deposited from a standard chromic acid bath increases from about 2.8809 to 2.8880 Å with increasing bath temperature from 40° to 75°C.
