AbstractIn patients with cystic fibrosis (CF) lung damage secondary to chronic infection is the main cause of death. Treatment of lung disease to reduce the impact of infection, inflammation and subsequent lung injury is therefore of major importance. As Pseudomonas aeruginosa is the dominant pathogen in CF patients it has been the major target of all treatment strategies, possible antibiotic regimens and recommendations for years. More sophisticated antibiotic therapies introduced over the last decades have helped to improve the prognosis in cystic fibrosis, but then new multidrug-resistant pathogens emerged.We present a case of cystic fibrosis in a 16-year-old boy with pulmonary exacerbation due to colistin-resistant Stenotrophomonas maltophilia. This case raises some interesting questions regarding the antibiotic policy and treatment options in our country for patients with CF and multidrug-resistant strains. Colistin is used at present in Bulgaria as a strategic last option for the CF patients but with the advent of new more drug-resistant strains therapeutic approach should change - for instance, there should be restrictions imposed on the use of levofloxacin and trimethoprim/sulfamethoxazole which are regarded as “cheap and not so potent” antibiotics suitable for any infection and use them only in strict dependence on the respective culture results.
Mendelssohn and Kant on Mathematics and Metaphysics
Authors: Callanan John 
Published: August 2016

AbstractThe difference between the method of metaphysics and the method of mathematics was an issue of central concern for Kant in both the Pre-Critical and Critical periods. I will argue that when Kant speaks of the ‘philosophical method’ in the Doctrine of Method in the Critique of Pure Reason (CPR), he frequently has in mind not his own methodology but rather the method of conceptual analysis associated with rationalism. The particular target is Moses Mendelssohn’s picture of analysis contained in his submission for the 1763 Prize Essay competition. By the time of the first Critique, I argue, Kant wants to maintain his own longstanding commitment to the distinctness of the methods of metaphysics and mathematics. However, Kant wants to use this same analysis of the source of the distinction to diagnose the origins of the dogmatism that is engendered by the method of the rationalists.

Abstract
Two novel coordination compounds, [Sr(atzp)2(H2O)2]·CH3OH (1) and [Sr(dtzpha)(H2O)3]·4H2O (2) [Hatzp=5-aminotetrazole-1-propionic acid, H2dtzpha=1,3-di(tetrazol-5-yl)benzene-N2,N2′-diacetic acid)], have been generated by using 5-aminotetrazole-1-propionic acid and 1,3-di(tetrazol-5-yl)benzene-N2,N2′-diacetic acid to react with strontium salts, respectively. X-ray diffraction analysis reveals that carboxylic groups of two ligands show the same coordination mode (the μ
1,1,3-COO coordination mode), compound 1 displays a 1D structure while compound 2 shows a 2D structure, which implies the influence of the number of the carboxylic acid groups. Luminescence properties of 1 and 2 were investigated at room temperature in the solid state.

Authors: Xu Guan , Zhang Xinyuan , Li Xiaotao , Su Jian , Hao Zhaobing 
Published: August 2016

Abstract
We present a reliable calibration method using the constraint of 2D projective lines and 3D world points to elaborate the accuracy of the camera calibration. Based on the relationship between the 3D points and the projective plane, the constraint equations of the transformation matrix are generated from the 3D points and 2D projective lines. The transformation matrix is solved by the singular value decomposition. The proposed method is compared with the point-based calibration to verify the measurement validity. The mean values of the root-mean-square errors using the proposed method are 7.69×10−4, 6.98×10−4, 2.29×10−4, and 1.09×10−3 while the ones of the original method are 8.10×10−4, 1.29×10−2, 2.58×10−2, and 8.12×10−3. Moreover, the average logarithmic errors of the calibration method are evaluated and compared with the former method in different Gaussian noises and projective lines. The variances of the average errors using the proposed method are 1.70×10−5, 1.39×10−4, 1.13×10−4, and 4.06×10−4, which indicates the stability and accuracy of the method.

Authors: Kong Weihang , Li Lei , Kong Lingfu , Liu Xingbin 
Published: August 2016

Abstract
In order to solve the problem of dynamic pure-water electrical conductivity measurement in the process of calculating water content of oil-water two-phase flow of production profile logging in horizontal wells, a six-group local-conductance probe (SGLCP) is proposed to measure dynamic pure-water electrical conductivity in horizontal oil-water two-phase flow. The structures of conductance sensors which include the SGLCP and ring-shaped conductance probe (RSCP) are analyzed by using the finite-element method (FEM). In the process of simulation, the electric field distribution generated by the SGLCP and RSCP are investigated, and the responses of the measuring electrodes are calculated under the different values of the water resistivity. The static experiments of the SGLCP and RSCP under different mineralization degrees in horizontal oil-water two-phase flow are carried out. Results of simulation and experiments demonstrate a nice linearity between the SGLCP and RSCP under different mineralization degrees. The SGLCP has also a good adaptability to stratified flow, stratified flow with mixing at the interface and dispersion of oil in water and water flow. The validity and feasibility of pure-water electrical conductivity measurement with the designed SGLCP under different mineralization degrees are verified by experimental results.

Published: August 2016

Abstract
Microvascular free flap surgery, has become an important part of reconstructive surgery during the last decades, as it allows closure of various tissue defects and recovery of organs function. Despite surgical progress resulting in high rates of transferred tissue survival, the risk of pedicle vessels thrombosis still remains a significant problem. A total of 108 articles from Pubmed and Science Direct databases published in 2005–2015 were analysed. This review of the literature assessed the influence of patient-dependent risk factors and different perioperative management strategies on development of microvascular free flap thrombosis. Sufficient evidence for risk associated with hypercoagulation, advanced age and certain comorbidities was identified. Presently, rotational thromboelastometry allows early hypercoagulability detection, significantly changing further patient management. Identification of flap thrombosis promoting surgery-related aspects is also essential in preoperative settings. Choice of anaesthesia and postoperative analgesia, administration of different types and amounts of fluids, blood products and vasoactive agents, temperature control are no less important in perioperative anaesthesiological management. More attention should be focused on timely preoperative evaluation of patient-dependent risk factors, which can influence anaesthesiological and surgical tactics during and after microvascular free flap surgery. Perioperative anaesthesiological management strategy continues to be controversial and therefore it should be performed based on thrombotic risk assessment and patient individual needs, thus improving flap survival rates and surgical outcome.

Authors: Móczár Balázs , Polgár Zsuzsanna , Mahler András 
Published: August 2016

Abstract
Design and modelling of raft foundations and selecting the value of coefficient of vertical subgrade reaction are still actively discussed topics in geotechnical and structural engineering. In everyday practice, soil–structure interaction is mostly taken into account by using the theory of ‘beam on elastic foundation’, in which the soil is substituted by a certain set of coefficients of subgrade reaction. In this study, finite element analysis of a building was performed using a geotechnical software (Plaxis 3D), which is capable of modelling the subsoil as a continuum, and a structural software (Axis VM), which uses the concept of ‘beam on elastic foundation’. The evaluation of the results and recommendations for everyday engineering practice are introduced in this paper.

Published: August 2016

Abstract
Multiple sclerosis (MS) and neuromyelitis optica (NMO) are inflammatory demyelinating disorders of the central nervous system (CNS). Various genetic and environmental factors have been identified to contribute to etiology of MS and NMO. Aquaporin 4 (AQP4), is the most abundant water channel in CNS. AQP4 is expressed in astrocytes of the brain, spinal cord, optic nerve and supportive cells in sensory organs. In contrast to MS, immunoreactivity of AQP4 is abolished in NMO lesions. However, conflicting results have been reported regarding the association between AQP4 polymorphisms and demyelinating disorders. Considering the ethnic differences of genetic variations, replications in other cohorts are required. In this study, single nucleotide polymorphisms (SNPs) of AQP4 gene in patients with NMO/neuromyelitis optica spectrum disorders (NMOSD), and MS in the Northern Han Chinese population were examined. Six selected AQP4 SNPs were genotyped by high-resolution melting (HRM) method. Compared with healthy control (HC), there was no significant difference of AQP4 allele and genotype frequency in MS or NMO/NMOSD group. This study showed no significant association of common AQP4 SNPs with MS or NMO/NMOSD, strongly suggesting that polymorphisms of AQP4 gene are unlikely to confer MS or NMO/NMOSD susceptibility, at least in Northern Han Chinese population.
Optical and Geometric Properties of Free Silica Nanoparticles Studied by Small-Angle X-Ray Scattering

Published: August 2016

Abstract
Elastic small-angle X-ray scattering (SAXS) of free silica (SiO2) nanoparticles is reported
(d = 100–180 nm). The particles were prepared by a modified Stöber synthesis in narrow size distributions
with controlled surface roughness and functionalization. Angle-resolved small-angle X-ray scattering patterns are shown to
be sensitive to these changes in particle properties. It is reported that there is an exponential decrease in scattered
X-ray intensity towards larger scattering angles as well as distinct oscillations, which is fully explained by Mie
theory. Small-angle X-ray scattering of mesoporous nanoparticles with rough surfaces is compared to that of microporous
nanoparticles with smooth surfaces, revealing distinct differences that are rationalized by diffuse scattering from
nanoparticle pores in addition to the dominating contribution of Mie scattering. Furthermore, results from small-angle
X-ray scattering experiments on functionalized silica nanoparticles are presented, where the incorporation of the dye
fluorescein isothiocyanate is found to cause changes in the optical properties of the nanoparticles, as compared to
non-functionalized samples. Small, but distinct deviations in particle size derived from electron microscopy and from
small-angle X-ray scattering are observed. These are rationalized by particle shrinking occurring in electron microscopy
as well as slight changes in optical properties of the nanoparticle samples.
Child Restraint Use and Driver Screening in Fatal Crashes Involving Drugs and Alcohol
Authors: Huang Yanlan , Liu Chang , Pressley Joyce C. 
Published: August 2016

BACKGROUND:There are reports that the incidence of alcohol-involved crashes has remained stable among fatally injured drivers while drug involvement has increased in recent years.METHODS:Data from the Fatality Analysis Reporting System (FARS) from 2010 to 2013 were used to examine drug and alcohol status of drivers (N = 10 864) of 4-wheeled passenger vehicles involved in a fatal crash while transporting a passenger aged 0 to 14 years (N = 17 179). Mixed effect multivariable logistic regression used SAS GLIMMIX to control for clustering. Odds ratios are reported with 95% confidence intervals (CIs).RESULTS:Only 28.9% of drivers were screened for both alcohol and drugs, and 56.7% were not tested for either. The total proportion of unrestrained child passengers increased nearly linearly by age. Findings ranged as high as 70% for 13- to 14-year-olds with drivers positive for drugs and alcohol. In multivariable adjusted models, inappropriate child seating with drivers who tested positive was as follows: alcohol, 1.30 (95% CI, 0.92–1.82); drugs, 1.54 (95% CI, 1.24–1.92); and for both drugs and alcohol, 1.88 (95% CI, 1.38–2.55). More than one-fourth were unrestrained with drivers positive for cannabis (27.7%). Overall mortality was approximately triple for unrestrained versus restrained (33.5% vs 11.5%; P &lt; .0001) and was higher in front-seated than rear-seated passengers (40.7% vs 31.5%; P &lt; .0001).CONCLUSIONS:Passengers were less likely to be appropriately seated and to be restrained when transported by a driver positive for drugs and alcohol, but this finding varied according to passenger age and drug/alcohol category.

Históricamente, el Istmo de Costa Rica y Panamá ha sido fuente de fascinación por su posición estratégica, uniendo América del Norte con América del Sur. En términos de biodiversidad, el Istmo es considerado una de las regiones más ricas del mundo. Orchidaceae es la familia de plantas más diversa en la zona, y el número de especies triplica a otras familias de angiospermas bien representadas como Rubiaceae, Fabaceae y Poaceae. Aunque todavía estamos lejos de conocer el número exacto de especies de orquídeas existentes en ambos países, en la actualidad la flora de orquídeas registradas para Costa Rica (1574 spp.) y Panamá (1372 spp.) suman en conjunto alrededor de 2010 especies; lo que representa 6,5-8,0% de todas las especies de orquídeas en apenas alrededor de 1% de la superficie terrestre del planeta. Pleurothallidinae y Laeliinae son los grupos más ricos en especies y contienen la mayor géneros: Lepanthes, Pleurothallis, Stelis y Epidendrum. Estos grupos superan significativamente los otros géneros registrados en términos de riqueza de especies. Algunos de los factores que explican esta diversidad taxonómica regional de orquídeas son el puente natural que une tres de los 25 puntos reconocidos en todo el mundo (Mesoamérica, Chocó / Darién / Ecuador Occidental y Andes tropicales), la influencia climática de los océanos Pacífico y Atlántico, y la reciente elevación de la Cordillera de Talamanca y la formación de estribaciones de Majé, Darién y San Blas, en Panamá y el oeste de Colombia. Aunque estos factores pueden explicar la alta diversidad de orquídeas en términos generales, se necesita información detallada para comprender la diversificación de especies, así como la evolución de la composición florística. Los inventarios florísticos actualizados (con una tasa de 25 nuevas especies / año) y el estudio de los mecanismos biológicos que han llevado a la diversificación evolutiva de Lepanthes (como uno de los géneros más grandes de orquídeas) son los principales proyectos de investigación en curso para dilucidar la evolución de Orchidaceae en Costa Rica y Panamá. Con este fin, presentamos algunos resultados preliminares de la investigación llevada a cabo en esta dirección que incluye la integración de estudios filogenéticos, ecología de la polinización, taxonomía y biogeografía.
New methodology for measuring the floating velocity of grain particles
Authors: Polyák Ilona Nagyné , Csizmazia Zoltán 
Published: August 2016

The physical characteristics of particles used in agriculture (seeds, fertiliser particles) can strongly influence their movements in the agricultural machine as well as in the air. The knowledge of the physical characteristics of particles is essential for the designer and operators. In this respect the size, size distribution, shape, mass, bulk density, real density, coefficient of friction and aerodynamic resistance of particles are of great importance. Among physical characteristics, aerodynamic properties are the most important for the description of seed movement in the air.
The knowledge of the aerodynamic characteristics of grains (floating velocity, aerodynamic resistance coefficient) is significant for the construction and operation of machines, which treat substances with air flow and in all cases when substances are moved in the air. The theory of the aerodynamic characteristics of regularly shaped bodies is well elaborated; however, grains (seed grains, fertilizer particles) applied in agricultural practice are irregularly shaped. Therefore, in our earlier research we started to study the physical characteristics of irregularly shaped grains. Due to their irregular shape, determining the size of grains is a troublesome process. A precise description of grains has to include several sizes (length, width, thickness) and can be obtained from the screen size of the corns.
To identify the aerodynamic characteristics of seeds, we have developed a new elutriator, in which airflow is supplied by a centrifugal fan. The air velocity was measured with a thermal sensor. The collecting of data was supported by a digital camera, and we analysed the collected data by an image processing, so we can describe the movement of the seeds, and we can determine precisely the terminal velocity of irregular shaped seeds.
The average moisture content of the samples was 13.42%. The individual mass of seeds varied between 0.1889 and 0.3758 g. The value of the mass of 1000 seeds used in general practice was 317.562 gr. The grain size varied: length between 7.76 and 11.81 mm, width between 6.77 and 9.99 mm, thickness between 4.41 and 5.85 mm. The suspension velocity varied between 9.14 m/s and 10.65 m/s.
Deconstructing Panty Pennants and Revealing Absent Presence
Authors: Ward Amber 
Published: August 2016

More multifaceted than the mere titles we maintain—as daughters, sisters, wives, and teachers, for example—sexuality is a part of our identity worth exploring and honoring. Women’s stories, gathered in a questionnaire, highlight sexual identity in Panty Pennants—an exhibition held in late 2012 at the Leedy-Voulkos Art Center in Kansas City, Missouri. The author uses a process of thinking with deconstruction to explore various texts from the exhibition. In doing this, she learns to hear silence, to see women as multi-dimensional, and to disrupt culturally learned hierarchies of unearned privilege and oppressive power for purposes of gender equity and social justice.

Published: August 2016

O ser humano transcende a natureza, não está limitado pela arbitrariedade das leis naturais, dos instintos. Essa liberdade possibilita a ação da vontade sobre a realidade e leva a que se interrogue por uma razão que oriente as escolhas. O texto procura mostrar como Kant e Hegel tentaram responder à pergunta pelo fundamento da ação, o primeiro através de um princípio universal e formal e o segundo procurando preencher a formalidade com conteúdo que possa determinar as ações concretas e particulares, complementando um ao outro.
