Rooting Depth, Soil Type, and Application Rate Effects on Creeping Bentgrass Injury with Amicarbazone and Methiozolin
Authors: Brosnan J. T. , Calvache S. , Breeden G. K. , Sorochan J. C. 
Published: January 2013

ABSTRACTAmicarbazone and methiozolin are herbicides with efficacy for annual bluegrass (Poa annua L.) control in creeping bentgrass (Agrostis stolonifera L.). Research was conducted to determine the effects of rooting depth and soil type on creeping bentgrass injury following amicarbazone and methiozolin applications. ‘Penncross’ creeping bentgrass was established in sand‐ and soil‐based rootzones using mini‐rhizotrons. Plants were treated with amicarbazone (49, 98, 196 g ha−1) or methiozolin (500, 1000, 2000 g ha−1) once root growth reached depths of 5, 10, or 15 cm. Amicarbazone was more injurious than methiozolin in both rootzones. Creeping bentgrass injury with amicarbazone measured 38% in the sand‐based rootzone compared with 62% in soil. This injury was accompanied by 54 to 69% reductions in root‐length density in the sand‐based rootzone and 42 to 81% reductions in soil. Methiozolin resulted in ≤12% creeping bentgrass injury, regardless of rootzone type or application rate, and reduced root‐length density 0 to 25%. Amicarbazone applications to plants rooted to 15 cm were less injurious than those rooted to 5‐ and 10‐cm depths. Responses indicate that methiozolin is less injurious to creeping bentgrass than amicarbazone and that rooting depth and soil type affect creeping bentgrass injury with amicarbazone.
Accounting Faculty Experiences with Practice-Oriented Fellowships
Authors: Krische Susan D. , Martin Roger D. , Wilks T. Jeffrey 
Published: January 2013

SYNOPSIS
We describe our experiences with practice-oriented fellowships along with survey data gathered from other full-time accounting faculty who participated in similar fellowships between 2000 and 2010 across a broad set of sponsoring organizations (including the Securities and Exchange Commission [SEC], the Financial Accounting Standards Board [FASB], public accounting firms, and other organizations). Our survey results identify commonalities in (1) faculty members' backgrounds, (2) fellowship administration and logistical issues surrounding the transition into fellowships, (3) the nature of the work experience during the fellowship, (4) transitions back to academia following the fellowships, and (5) faculty members' evaluations of their fellowship experience. By reporting on the issues, costs, and benefits from participating in practice-oriented fellowships, we hope faculty will understand more about these opportunities and be more likely to participate in practice-oriented fellowships. We also hope that this paper helps universities and sponsoring organizations understand better the needs and concerns of faculty members who are considering whether to participate in these fellowships.
A Formula for Popp’s Volume in Sub-Riemannian
Geometry
Authors: Barilari Davide , Rizzi Luca 
Published: January 2013

Abstract
For an equiregular sub-Riemannian manifold M, Popp’s volume
is a smooth volume which is canonically associated with
the sub-Riemannian structure, and it is a natural generalization
of the Riemannian one. In this paper we prove a general
formula for Popp’s volume, written in terms of a frame adapted
to the sub-Riemannian distribution. As a first application of
this result, we prove an explicit formula for the canonical sub-
Laplacian, namely the one associated with Popp’s volume.
Finally, we discuss sub-Riemannian isometries, and we prove
that they preserve Popp’s volume. We also show that, under
some hypotheses on the action of the isometry group of M,
Popp’s volume is essentially the unique volume with such a
property.
High-order fractional partial differential equation
transform for molecular surface construction
Authors: Hu Langhua , Chen Duan , Wei Guo-Wei 
Published: January 2013

Abstract
Fractional derivative or fractional calculus plays a significant
role in theoretical modeling of scientific and engineering problems.
However, only relatively low order fractional derivatives
are used at present. In general, it is not obvious what role
a high fractional derivative can play and how to make use of
arbitrarily high-order fractional derivatives. This work introduces
arbitrarily high-order fractional partial differential equations
(PDEs) to describe fractional hyperdiffusions. The fractional
PDEs are constructed via fractional variational principle.
A fast fractional Fourier transform (FFFT) is proposed to
numerically integrate the high-order fractional PDEs so as to
avoid stringent stability constraints in solving high-order evolution
PDEs. The proposed high-order fractional PDEs are
applied to the surface generation of proteins. We first validate
the proposed method with a variety of test examples in
two and three-dimensional settings. The impact of high-order
fractional derivatives to surface analysis is examined. We
also construct fractional PDE transform based on arbitrarily
high-order fractional PDEs. We demonstrate that the use of
arbitrarily high-order derivatives gives rise to time-frequency
localization, the control of the spectral distribution, and the
regulation of the spatial resolution in the fractional PDE transform.
Consequently, the fractional PDE transform enables the
mode decomposition of images, signals, and surfaces. The
effect of the propagation time on the quality of resulting molecular
surfaces is also studied. Computational efficiency of
the present surface generation method is compared with the
MSMS approach in Cartesian representation. We further validate
the present method by examining some benchmark indicators
of macromolecular surfaces, i.e., surface area, surface
enclosed volume, surface electrostatic potential and solvation
free energy. Extensive numerical experiments and comparison
with an established surface model indicate that the proposed
high-order fractional PDEs are robust, stable and efficient
for biomolecular surface generation.
Pseudolite signal tests
Authors: Rapinski J. , Cellmer S. , Rzepecka Z. 
Published: January 2013

ABSTRACT
Pseudolites are ground based GNSS signal transmitters that have already been used in the project where visibility to the GNSS satellites is limited, however there are still many issues that need enhancement. A prototype of a low-cost pseudolite is being designed and assembled at the University of Warmia and Mazury. The goal of the project is to apply the pseudolite as an augmentation to GNSS positioning tasks in geodetic engineering projects. This paper presents the results of first prototype testing in the area of code generation, carrier frequency and signal power.

Published: January 2013

Abstract
Antimicrobial activities of the methanolic extracts from the leaves and flowers of Lippia nodiflora L. (Verbenaceae), were studied by the disk diffusion method. The extracts showed antimicrobial impact on bacteria such as Bacillus subtilis, B. cereus, Micrococcus luteus, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonia, K. oxytoca and Esherichia coli as well as fungi such Aspergillus niger and Candida albicanse. The results showed that increasing concentrations of extracts increased the antimicrobial activities in all of the microorganisms. Bacteria were more sensitive than fungi, and gram positive bacteria were more sensitive than gram negative ones.

Abstract
In the southern part of Poland, ground beetle fauna was studied in the first large-scale Bt maize experiment. The aim of this study was to determine the long term impact of the Bt maize cultivar in comparison to conventional plants, on selected non-target arthropods. The DKC 3421 YG cultivar (Bt maize) and the respective isogenic non-Bt varieties (DKC 3420) were cultivated at two locations: (a) Budziszów near Wrocław and in Głuchów near Rzeszów in the south-eastern region of Poland, in the 2008-2010 growing seasons. For comparative analysis, two additional non-Bt cultivars sprayed with a lambda-cyhalotrine insecticide were also included. To monitor population density of surface-active invertebrates of the Carabidae family, eighty pitfall traps were used at each location. The average number of ground beetle populations in the Bt-maize cultivar DKC 3421 YG did not significantly differ from the number of beetles in the conventional ones. Significant differences between the number of beetles occurred on individual dates only. Usually, these differences related to the considerably smaller total number of beetles in the whole replication. Probably, the variation in the number of beetles was caused by climatic factors or the terrain layout, therefore it cannot be related to the cultivar effect.

Abstract
The list of species of the plant parasitic nematodes presented in this paper (133 species belonging to 14 families) is based on the results of faunistic research conducted in the Wielkopolska region by Polish nematologists up until the year 2010, and the results obtained from the project “Elaboration of Innovative Methods for Rapid Identification of Nematodes Causing Damage to the Economy” managed by the Museum and Institute of Zoology of the Polish Academy of Sciences. During the two years of the project (2010-2011) we found 21 species of nematodes which had not yet been reported in the list of species from the Wielkopolska region. Two of them were reported for the first time in Poland.
Measurement and classification methods using the ASAE S572.1 reference nozzles
Authors: Fritz Bradley Keith , Hoffmann Wesley Clint , Czaczyk Zbigniew , Bagley William , Kruger Greg , Henry Ryan 
Published: January 2013

Abstract
An increasing number of spray nozzle and agrochemical manufacturers are incorporating droplet size measurements into both research and development. Each laboratory invariably has their own sampling setup and procedures. This is particularly true about measurement distance from the nozzle and concurrent airflow velocities. Both have been shown to significantly impact results from laser diffraction instruments. These differences can be overcome through the use of standardized reference nozzles and relative spray classification categories. Sets of references nozzles, which defined a set of classification category thresholds, were evaluated for droplet size under three concurrent air flow velocities (0.7, 3.1 and 6.7 m/s). There were significant, though numerically small, differences in the droplet size data between identical reference nozzles. The resulting droplet size data were used to categorize a number of additional spray nozzles at multiple pressure and air flow velocities. This was done to determine if similar classifications were given across the different airspeeds. Generally, droplet size classifications agreed for all airspeeds, with the few that did not, only differing by one category. When reporting droplet size data, it is critical that data generated from a set of reference nozzles also be presented as a means of providing a relative frame of reference.
Efficacy of fungicides and essential oils against bacterial diseases of fruit trees
Authors: Mikiciński Artur , Sobiczewski Piotr , Berczyński Stanisław 
Published: January 2013

Abstract
In the framework of the performed studies, the antibacterial activity of the following fungicides was evaluated: Miedzian 50 WG (active substance - a.s. 50% copper oxychloride), Ridomil MZ Gold 68 WG (a.s. 3.8% metalaxyl-M and 64%, mancozeb), Euparen Multi 50 WG (a.s. 50% tolylfluanid), Captan 80 WG [a.s. 80% N-(captan)], Dithane Neotec 75 WG (a.s. 75% mancozeb). The evaluation also concerned the essential oils: lavender, sage, lemon balm, clove, and a preparation based on thyme oil (BioZell). Each preparation and compound was tested against the following bacterial pathogens: Erwinia amylovora, Xanthomonas arboricola pv. corylina, X. arboricola pv. juglandis, Pseudomonas syringae pv. syringae, Agrobacterium tumefaciens (presently Rhizobium radiobacter). Each preparation and compound was tested at a concentration of 1,000 ppm of active substance. Copper oxychloride was also tested at a concentration of 1,500 ppm. Among the tested fungicides, metalaxyl-M with mancozeb, mancozeb alone, and copper oxychloride inhibited all of the tested strains of pathogenic bacteria. Tolylfluanid did not inhibit any of the bacteria used. Out of the investigated essential oils, the strongest inhibitors of bacteria were: sage, cloves, and BioZell.
The protective activity of the above mentioned fungicides was also evaluated in vivo. They were assessed against fire blight on apple blossoms and pear fruitlets, against bacterial canker on sweet cherry fruitlets, and against crown gall on sunflower seedlings (the test plant). All fungicides were applied at the same concentrations as those in the in vitro tests. Only copper oxychloride was found to show protective activity against the studied diseases. This result indicates that the antibacterial properties of the other fungicides did not correspond with their activity on the plant organs used in the in vivo experiment.
Heat transfer during condensation of refrigerants in tubular minichannels
Authors: Bohdal Tadeusz , Charun Henryk , Sikora Małgorzata 
Published: January 2013

Abstract
The present paper describes the results of experimental investigations of heat transfer during condensation of R134a, R404A and R407C in pipe minichannels with internal diameters 0.31-3.30 mm. The results concern investigations of the local heat transfer coefficient. The results were compared with the correlations proposed by other authors. Within the range of examined parameters of the condensation process in minichannels made of stainless steel, it was established that the values of the heat transfer coefficient may be described with Akers et al., Mikielewicz and Shah correlations within a limited range of the mass flux density of the refrigerant and the minichannel diameter. On the basis of experimental investigations, the authors proposed their own correlation for the calculation of local heat transfer coefficient.
Experimental tests for the occurence of convective heat transfer within the bed of rectangular steel profiles
Authors: Wyczółkowski Rafał , Musiał Dorota 
Published: January 2013

Abstract
The paper describes tests intended to examine the occurrence
of natural convection within the space occupied by 40×20 mm rectangular
steel sections. Within these tests the bed of four layers of section was
heated by the electric palate heater. Depending on the manner in which
the heater was positioned, the tests were divided into two series. In the
case of heating from above, the heat flowing through the bed is transferred
only by conduction and radiation. When heating the bed from below, in
addition to conduction and radiation, also a convective heat transfer will
occur. Should this be the case, it will result in the intensification of the heat
exchange. The results of measurements carried out have not demonstrated
that the occurrence of any possible natural convection would influence the
development of a temperature field in this type of charge.
Partial limb skeleton of a “giant penguin” Anthropornis from the Eocene of Antarctic Peninsula
Authors: Jadwiszczak Piotr 
Published: January 2013

Abstract: The fossil record of the Antarctic penguins is dated to the late Paleocene of Sey− mour (Marambio) Island, but the largest sphenisciforms, generaAnthropornisandPalae−eudyptes, originate from the Eocene La Meseta Formation. Here, the most complete large−scale reconstruction of a limb skeleton (a whole wing and a partial hind leg) of a Paleogene Antarctic penguin is reported. All bones are attributable to a single individual identified asAnthropornissp. The comparative and functional analyses of the material indi− cate that this bird was most probably well−adapted to land and sea while having a number of intriguing features. The modern−grade carpometacarpal morphology is unique among known Eocene Antarctic species and all but one more northerly taxa.
Succession of vascular plants in front of retreating glaciers in central Spitsbergen
Authors: Prach Karel , Rachlewicz Grzegorz 
Published: January 2013

Abstract
Vegetation succession in front of five retreating glaciers was studied using phytosociological relevés (60) located at different distances between the Little Ice Age (LIA) moraines and the present glacier fronts around Petunia Bay. Approximate dating of succession stages was based on a study of the changing position of glacier fronts in the past approximately 100 years. The described succession corresponds to the uni-directional, non-replacement model of succession. All constituent species, except one, present in the nearby old tundra have colonized the glacier forelands since the end of the LIA. The first species appeared about 5 years after deglaciation. The latest succession stages closely re- semble the old tundra.
Variability of contemporary vegetation around Petuniabukta, central Spitsbergen
Authors: Prach Karel , Klimešová Jitka , Košnar Jiří , Redčenko Olexii , Hais Martin 
Published: January 2013

Abstract
Vegetation was described in various spatial scales in the area of 37.8 km2 including distinguishing vegetation units, vegetation mapping, recording phytosociological relevés (53), and completing species lists of vascular plants (86), mosses (124) and lichens (40). Phytosociological relevés were elaborated using ordination methods DCA and CCA. The relevés formed clusters corresponding well to a priori assigned vegetation units. Slope and stoniness significantly influenced the vegetation pattern. Despite the high latitude (nearly 80° N), the vegetation is rather rich in species. Non-native species do not expand. The moss Bryum dichotomum is reported for the first time from Svalbard archipelago.

Competitiveness of products, equipment and technological processes in machine-building
In the times of crisis, the competitive edge of a desired production acquires a special value. The paper considers the structure of competitiveness as a unity of quality, expenditure, profit and prices. It describes a method of forming competitiveness exemplifying, at the same time, an erroneous interpretation of competitiveness and methods of its “rapid determination”. To analyze and synthesize an integral level of competitiveness, one may use the SADT-method of detailed step-by-step hierarchy of the objects under study.
Possibility of NOx emission reduction from combustion process using sewage sludge gasification gas as an additional fuel
Authors: Werle Sebastian 
Published: January 2013

Abstract
In the paper, a numerical simulation of the co-combustion process of sewage sludge gasifi cation syngas in a hard coal-fi red boiler was done. Two different syngases (SS1 and SS2) were taken in consideration. Additional (reburning) fuel was injected into the combustion chamber, which was modeled as a plug fl ow reactor (PFR). The molar fl ow rates ratio of reburning fuel is assumed to be 5.0%, 7.5%, 10.0%, 12.5% and 15.0% of the whole exhaust. The simulations were conducted for constant pressure equal to 1atm for temperatures range from 600 to 1400 K. It was assumed that a fl ue gases which enters the reburning zone contains 300 ppm of NO and that during combustion only NO is formed without other NOx. Results show that that gas from sewage sludge gasifi cation gives reburning effi ciency of up to 90%. Calculation shows also an optimum value of temperature reburning for gas from sewage sludge gasifi cation which is equal to 1200 K. The type of the sewage sludge has no strong infl uence on the NO reduction.

Consumption of the sewing thread of jean pant using taguchi design analysis
Authors: Jaouachi B. , Khedher F. , Mili F. 
Published: January 2013

Abstract

This work deals with the evaluation of sewing thread consumption in jeans and classic pants clothing. Six different
input parameters are chosen and used for investigation. To objectively evaluate their contributions, a Taguchi design
analysis was applied. Based on the comparison between each input parameter effect, this experimental analysis
helped us to classify the overall tested factors. Indeed, our findings show that the sewing yarn affects widely the
thread consumption during stitching of the pant. In spite of their non negligible impact, the number of stitches per
cm and the needle type can be considered as influential input factors on thread consumption. In our experimental
design the other tested factors were kept constant.

Object
Intracerebral hemorrhage (ICH) is a major cause of death and disability throughout the world. Surgical techniques are limited by their invasive nature and the associated disability caused during clot removal. Preliminary data have shown promise for the feasibility of transcranial MR-guided focused ultrasound (MRgFUS) sonothrombolysis in liquefying the clotted blood in ICH and thereby facilitating minimally invasive evacuation of the clot via a twist-drill craniostomy and aspiration tube.

Methods and Results
In an in vitro model, the following optimum transcranial sonothrombolysis parameters were determined: transducer center frequency 230 kHz, power 3950 W, pulse repetition rate 1 kHz, duty cycle 10%, and sonication duration 30 seconds. Safety studies were performed in swine (n = 20). In a swine model of ICH, MRgFUS sonothrombolysis of 4 ml ICH was performed. Magnetic resonance imaging and histological examination demonstrated complete lysis of the ICH without additional brain injury, blood-brain barrier breakdown, or thermal necrosis due to sonothrombolysis. A novel cadaveric model of ICH was developed with 40-ml clots implanted into fresh cadaveric brains (n = 10). Intracerebral hemorrhages were successfully liquefied (> 95%) with transcranial MRgFUS in a highly accurate fashion, permitting minimally invasive aspiration of the lysate under MRI guidance.

Conclusions
The feasibility of transcranial MRgFUS sonothrombolysis was demonstrated in in vitro and cadaveric models of ICH. Initial in vivo safety data in a swine model of ICH suggest the process to be safe. Minimally invasive treatment of ICH with MRgFUS warrants evaluation in the setting of a clinical trial.
