Possibilities and limitations of constructability concept in construction industry in Croatia

The constructability concept development was triggered by the attempts to integrate the contractor knowledge and experience at the design stage. The very selection of the appropriate procurement model during the contract stage represents one of the concept implementation models. This paper deals with the stage and project participant integration, those being the essential constructability concept implementation elements. For this purpose a research including five Croatian building construction projects was conducted. The construction projects were analyzed and described by applying the ″multiple case study″ scientific method. This paper presents the processing algorithm and results for the two selected cases, the first of which with the traditional procurement model and the second with the alternative management oriented procurement model, as well as the results of the case study conducted on all five projects. The results lead to specific conclusions and recommendations for applying the models at the markets of less developed countries. The changes in construction project traditional procurement model domination can not be made radically due to culture and financial reasons. They require a change of awareness and investment of significant resources. Due to the stated reasons an improved traditional procurement model introduction is proposed. The measurement introduction must be adapted to every single project in order to improve the construction project procurement procedures, one must make an influence on the wider community where the project takes place and influence the changes primarily within the legislative and the institutional frames.
Fast simulation of Digital Spiking Silicon Neuron model employing reconfigurable dataflow computing

A new simulation scheme of the Digital Spiking Silicon Neuron (DSSN) model is proposed. This scheme is based on the reconfigurable dataflow computing paradigm and targets the Maxeler MaxWorkstation. Compared to the previous implementation of the DSSN network, the new scheme has the virtues of better flexibility and better programmability. More importantly, computing with dataflow cores takes good advantage of the intrinsic parallelism of the reconfigurable hardware and better pipelining is achievable. The proposed scheme has good potential of conducting large-scale and fast simulation of the DSSN-model-based network which is pivotal to future neuroscience research.
Pseudomonas aeruginosa ventilator associated pneumonia: improved outcomes with earlier follow-up

It is not clear what is the appropriate timing to follow-up patients with ventilator-associated pneumonia (VAP) and Clinical Pulmonary Infection Score ＞6 between days 3-5 of an appropriate antibiotic treatment. We studied 122 patients with Pseudomonas aeruginosa VAP. A follow-up respiratory sample was collected on days three or five (”day-three” and ”day-five” group) and treatment was modified 48h later. Molecular typing identified super-infections or persistence. For serial data another respiratory sample was collected, on day three from the ”day-five” group and on day five from the ”day-three” group. Sixty patients, in the ”daythree” group compared to 62 in the ”day-five” group, had reduced fourteen-day mortality (18.3% and 38.7%; p=0.01) and fewer days in intensive care unit (17.2 ± 4.3 compared to 27.3 ± 4.7, p＜0.05). Eighteen patients of the ”dayfive” group were diagnosed with super-infection and 22 with persistence on day five, of whom 14 and 19 had been having these patterns since day three. For patients with Pseudomonas aeruginosa VAP and Clinical Pulmonary Infection Score ＞6, improved fourteen-day mortality and shorter duration of stay in health-care facilities were observed with earlier follow-up.
Specific endoscopic features of ulcerative colitis complicated by cytomegalovirus infection.

AIM To identify specific colonoscopic findings in patients with ulcerative colitis (UC) complicated by cytomegalovirus (CMV) infection. METHODS Among UC patients who were hospitalized due to exacerbation of symptoms, colonoscopic findings were compared between 15 CMV-positive patients and 58 CMV-negative patients. CMV infection was determined by blood test for CMV antigenemia. Five aspects of mucosal changes were analyzed (loss of vascular pattern, erythema, mucosal edema, easy bleeding, and mucinous exudates) as well as five aspects of ulcerative change (wide mucosal defect, punched-out ulceration, longitudinal ulceration, irregular ulceration, and cobblestone-like appearance). Sensitivity, specificity, positive predictive value, and negative predictive value of each finding for CMV positivity were determined. RESULTS The sensitivity of irregular ulceration for positive CMV was 100%. The specificity of wide mucosal defect was 95%. Punched-out ulceration and longitudinal ulceration exhibited relatively high sensitivity and specificity (more than 70% for each). CONCLUSION Specific colonoscopic findings in patients with UC complicated by CMV infection were identified. These findings may facilitate the early diagnosis of CMV infection in UC patients.
Fine-structure intervals for the lowest P terms in the Cu, Zn, Ga, and Br isoelectronic sequences for Z <= 92.

Theoretical and semiempirical predictions of fine-structure intervals for the lowest P terms in the Cu, Zn, Ga, and Br sequences are presented for all ions with Z less than or equal to 92. Through the use of screening parameter reductions of both the existing data base and the ab initio multiconfiguration Dirac-Fock computations reported herein, a new empirical decomposition has been discovered that permits measurements for the Cu sequence to be combined with theoretical computations to make precise predictions for the Zn, Ga, and Br sequences. These predictions are of higher precision than could be obtained solely by ab initio methods, and extend to much higher Z than semiempirical extrapolations alone would permit. These results provide insights into the interaction of the active and core electrons, and test a method that is applicable to many other systems.
Application of a Hierarchical Model Incorporating Intrafamily Correlation and Cluster Effects

Background:Research interventions at the family level often include individual- and group-level data that can present an analytic challenge. The study that motivated this article was an intervention study conducted with elementary school children and their parents. Randomization occurred at the school level, with families nested within schools. Repeated measurements collected from children and parents at different time points presented modeling challenges, including how to specify the covariance structure correctly among all measurements. Objectives:The aim of this study was to introduce a mixed model with random effects to model the correlations among family members, repeated measures, and the grouping effect. Methods:A hierarchical random-effect model was used that included both fixed and random effects; time and intervention-by-time variables were included as fixed effects, the school-specific variable was included as random effect, and the intrafamily correlation was modeled through a spatial autoregression covariance matrix. Comparisons were made between the performance of the proposed modeling method and that of other parsimony models using Akaike's Information Criterion (AIC). Results:The proposed modeling method produced a 3% and 9% reduction in AIC values, respectively, compared with the two other models. The likelihood ratio test further confirmed that the full model was better than the other two models (p < .0001 for both models). Discussion:The data suggest that using the proposed mixed model technique will produce a significantly better model fit for intrafamily correlation with a nested study design.
Influence of stencil design and parameters of printing process on lead-free paste transfer efficiency

Stencil design and stencil forming technique as well as parameters of solder paste printing process have an important influence on the volume and shape of solder paste deposited on the PCB pads and on the quality of solder joints. These factors become more crucial for fine pitch devices soldered in lead-free process. In the paper the results of experimental trials including selection of printing parameters, stencil materials and stencil forming technique as well as influence of different shapes of stencil apertures on transfer efficiency are discussed. The volume and shape of printed solder paste were measured and monitoring using microscopes and 3D inspection system.
Phylogenetic Status of Two Undescribed Zygomycete Species from Korea: Actinomucor elegans and Mucor minutus

Abstract During a survey of fungal diversity of the order Mucorales, three zygomycete isolates, CNUFC-YR113-1, CNUFCKNU16-7, and CNUFC-BS1-1 were isolated from freshwater and soil samples in Korea. The strains were analyzed both morphologically and phylogenetically based on internal transcribed spacer and 28S rDNA gene sequences. Based on their morphology and phylogeny, the CNUFC-YR113-1 and CNUFC-KNU16-7 isolates were identified as Actinomucor elegans, and CNUFC-BS1-1 was identified as Mucor minutus. To the best of our knowledge, the species A. elegans and M. minutus, belonging to an undiscovered taxon, have not been previously described in Korea.
Cell‐culture‐based immunochromatography for rapid detection of group A human rotaviruses in aquatic environments

In an effort to detect rapidly and conveniently the infectious waterborne group A human rotaviruses that cause diarrhea in infants and children, the authors developed the first‐ever cell‐culture‐based immunochromatography method. An immunochromatography kit interacted only with the human rotaviruses VP6 antigen, and the cell‐culture‐based immunochromatography detected group A human rotaviruses with a sensitivity as low as 1.99 TCID50 ml−1. This detection sensitivity was similar to that of the cytopathic effect‐based method. There were no actual differences between the sensitivity of this method and that of the real‐time reverse transcription polymerase chain reaction method, which is known as a method with a relatively high sensitivity. Furthermore, while cell culture detection methods, that is total culturable virus assay, can determine only the presence of infectious waterborne viruses, the cell‐culture‐based immunochromatography is advantageous for the accurate detection of group A human rotaviruses. Compared with the real‐time reverse transcription polymerase chain reaction method, the cell‐culture‐based immunochromatography is advantageous because it requires a relatively simple process that enables easy quality controls and low test costs. Thus, this study proposed a new method for the identification of group A human rotaviruses, and it is suggested that this cell‐culture‐based immunochromatography may be applied to detect group A human rotaviruses in aquatic environments.
PratA, a Periplasmic Tetratricopeptide Repeat Protein Involved in Biogenesis of Photosystem II in Synechocystis sp. PCC 6803*

The light reactions of oxygenic photosynthesis are mediated by multisubunit pigment-protein complexes situated within the specialized thylakoid membrane system. The biogenesis of these complexes is regulated by transacting factors that affect the expression of the respective subunit genes and/or the assembly of their products. Here we report on the analysis of the PratA gene from the cyanobacterium Synechocystis sp. PCC 6803 that encodes a periplasmic tetratricopeptide repeat protein of formerly unknown function. Targeted inactivation of PratA resulted in drastically reduced photosystem II (PSII) content. Protein pulse labeling experiments of PSII subunits indicated that the C-terminal processing of the precursor of the reaction center protein D1 is compromised in the pratA mutant. Moreover, a direct interaction of PratA and precursor D1 was demonstrated by applying yeast two-hybrid analyses. This suggests that PratA represents a factor facilitating D1 maturation via the endoprotease CtpA. The periplasmic localization of PratA supports a model that predicts the initial steps of PSII biogenesis to occur at the plasma membrane of cyanobacterial cells.
A novel compact three-port dielectric resonator antenna with reconfigurable pattern for WLAN systems

Splitting a cylinder dielectric resonator into four uniform quarters generates a new dielectric resonator antenna (DRA) shape, which is named a quarter volume of cylinder dielectric resonator antenna (QVCDRA) in the paper. On the basis, a novel compact three-port dielectric resonator antenna with reconflgurable radiation pattern is presented for WLAN systems at 5.2GHz. A i10dB impedance bandwidth of 16.20%, covering the frequency range from 4.75GHz to 5.54GHz, is obtained with an isolation of lower than i19dB. The structure consists of three QVCDRAs that arrange evenly around Z axis, and as a result possesses the advantage of compact structure, wide impendence band and reconflgurable radiation patterns. The volume of the proposed three-port DRA without ground plane is only 0:0216‚ 3 (‚d is the dielectric wave length at the central operation frequency). The proposed antenna is analyzed in detail. Antenna prototype is fabricated and tested. The simulation and test results are in good agreement.
Molecular aspects of iron absorption: Insights into the role of HFE in hemochromatosis

Hereditary hemochromatosis is the most common genetic disorder occurring in persons of northern European descent, and the clinical hallmark of the disease is the gradual accumulation of iron in internal organs, especially the liver, heart, and pancreas, which ultimately leads to organ failure. HFE, the gene that is defective in the majority of cases, was identified in 1996 and, although the exact role that HFE plays in the uptake and utilization of iron is not yet clear, important aspects of HFE function are emerging. Identification and studies of new proteins involved in the absorption of iron in the gut and in somatic cells has led to a clearer picture of how humans absorb iron from the diet and regulate this absorption to meet metabolic needs and to balance body iron stores. This review focuses on the molecular aspects of iron absorption and the role that HFE may play in these processes.
SELECCIÓN DE INDICADORES DE CALIDAD DE SUELO PARA DETERMINAR LOS EFECTOS DEL USO Y PRÁCTICAS AGRÍCOLAS EN UN ÁREA PILOTO DE LA REGIÓN CENTRAL DE CÓRDOBA

El objetivo de este estudio fue determinar los indicadores que mejor representan la calidad de un suelo del area central de la provincia de Cordoba. El estudio se realizo sobre un Haplustol tipico. Se evaluaron seis tratamientos. En cada tratamiento se seleccionaron tres sitios de ensayo, en los que se determino contenido de carbono organico (CO); nitrogeno total (NT); pH; conductividad electrica; fosforo extractable (PE); carbono liviano; carbono de acidos humicos y carbono de acidos fulvicos; densidad aparente; cambio en el diametro medio ponderado de agregados (CDMP); espesor del horizonte superficial (HzA) y profundidad del CO3Ca. Se utilizo analisis de componente principales para evaluar la relacion existente entre parametros de suelo medidos, entre parametros y tratamientos y entre tratamientos. Los resultados de este estudio muestran que los indicadores mas sensibles y sencillos de medir para evaluar calidad de suelos estan relacionados a la fertilidad de los mismos: materia organica (CO y sus fracciones), NT, PE y a la susceptibilidad a la erosion: CDMP, profundidad del CO3Ca y espesor del HzA. La disminucion de los contenidos de CO y sus fracciones, macronutrientes (NT y PE) y el aumento en la susceptibilidad a la erosion hidrica a medida que se prolongan los anos de agricultura y se incrementan las practicas tales como monocultivo de soja y siembra convencional, evidencian el deterioro de la calidad del suelo en relacion a los sitios bajo bosque nativo que son los que presentan el maximo potencial. Bajo condiciones de semiaridez, la siembra directa no logro mejorar significativamente las caracteristicas fisicas del suelo ni el contenido de CO y sus fracciones cuando se realizo monocultivo de soja.

A novel 8-joint ultrasound score is useful in daily practice for rheumatoid arthritis

Abstract Objectives. To investigate the optimal number and combination of joints to be assessed by power Doppler ultrasonography (PDUS) in daily practice for rheumatoid arthritis (RA). Methods. PDUS were performed in 24 joints, including all proximal interphalangeal, metacarpophalangeal (MCP), and bilateral wrist and knee joints in 234 patients with RA. PD signals were scored semiquantitatively from 0 to 3 in each joint, and total PD score-24 was calculated by summing them up as comprehensive assessment. Results. Positive PD signals were more frequently found in bilateral wrist, knee, and the second and third MCP joints than the other joints. The individual PD scores of these 8 joints also showed higher correlation coefficients with total PD score-24 (rs ≥ 0.4). Among the sum PD scores of various selected joint combinations, the score of the combination of 8 joints (total PD score-8), including bilateral second and third MCP, wrist, and knee joints, showed the highest sensitivity and negative predictive value (98.1% and 96.2%, respectively). Total PD score-8 showed high correlation with the total PD score-24 (rs = 0.97, p < 0.01). Conclusions. Total PD score-8 is simple and efficient enough for monitoring disease activity and judging imaging remission of RA in daily practice.
Reliable recognition of handwritten digits using a cascade ensemble classifier system and hybrid features

Aiming at a high recognition rate and a low error rate at the same time, a cascade ensemble classifier system is proposed for the recognition of handwritten digits. The tradeoff among the error, rejection and recognition rates of the recognition system is analyzed theoretically. Three solutions are proposed: (i) extracting more discriminative features to attain a high recognition rate, (ii) using ensemble classifiers to suppress the error rate, and (iii) employing a novel cascade system to enhance the recognition rate and to reduce the rejection rate. Based on these strategies, seven sets of discriminative hybrid features and three sets of randomly selected features are extracted and used in the different layers of the cascade recognition system. Novel gating networks are used to congregate the confidence values of three parallel Artificial Neural Networks (ANNs) classifiers. The weights of the gating networks are trained by the Genetic Algorithms (GAs) to achieve the overall optimal performance. Experiments are conducted on the MNIST handwritten numeral database with encouraging results: a high reliability of 99.96% with a minimal rejection, or 99.59% correct recognition rate without rejection in the last cascade layer. In the verification model, a novel multi-modal nonparametric analysis for optimal feature dimensionality reduction is proposed. The computational complexity of our proposed algorithm is much lower than that of other similar approaches found in the literature. Experiments demonstrate that our proposed method can achieve a high feature compression performance without sacrificing its discriminant ability. The results of dimensionality reduction make the ANNs converge more easily. For the verification of confusing handwritten numeral pairs, our proposed algorithm is used to congregate features, and it outperforms the PCA and compares favorably with other nonparametric discriminant analysis methods.
Compact Fractal Left-Handed Structures for Improved Cross-Polarization Radiation Pattern

A set of two-dimensional (2-D) left handed (LH) transmission line (TL) structures are proposed based on the single-layered and double-layered fractal-perturbed mushrooms. The effects of the Koch Island on the LH characteristics have been investigated physically by examining the dispersion diagram of the LH structure with and without fractal perturbations, showing that the parasitic transverse electric mode has been considerably suppressed without any deteriorative penalty on the dominant transverse magnetic mode. Therefore, the interaction of the degenerated parasitic mode with the operation modes has been considerably weakened. The concept has been employed to suppress the cross-polarization (XP) radiation of a microstrip antenna which incorporates a 2 × 2 array of the LH structure into a conventional microstrip patch. Numerical and experimental results indicate that the XP radiation (<; -30dB) has been notably reduced at three working frequencies (f-1 = 1.5, f0 = 2.96 and f+1 = 3.7 GHz) while the antenna performances such as gain, co-polarization radiation and impedance matching are without any deterioration.
CFD Modeling and Validation of Temperature and Flow Distribution in Air-Conditioned Space

Creating suitable thermal conditions for satisfying human desires, the thermal comfort has been recognized to be an essential requirement of the indoor environment. Thermal comfort is related to temperature and airflow distributions in air conditioning space, which play an important role in optimum design of air-conditioning system or ventilation system. No such general CFD model can be applicable for airflow and temperature distribution in room due to the suitability of turbulent models are dependent on application, operating conditions and other factors. The main aim of the present study is to investigate the airflow and temperature distribution of air-conditioning space. For this purpose, an experimental study on flow pattern and velocity distribution in an enclosed space with single inlet and outlet has been conducted. The flow pattern, velocity and temperature distributions in the above enclosed space have been investigated using three dimensional CFD simulation and the results obtained from the simulation are validated with experimental data. Results show that H �
What is the mechanism of ParA‐mediated DNA movement?

The stable maintenance of low‐copy‐number plasmids requires active partitioning, with the most common mechanism in prokaryotes involving the ATPase ParA. ParA proteins undergo intricate spatiotemporal relocations across the nucleoid, dynamics that function to position plasmids at equally spaced intervals. This spacing naturally guarantees equal partitioning of plasmids to each daughter cell. However, the fundamental mechanism linking ParA dynamics with regular plasmid positioning has proved difficult to dissect. In this issue of Molecular Microbiology, Vecchiarelli et al. report on a time‐delay mechanism that allows a slow cycling between the nucleoid‐bound and unbound forms of ParA. The authors also propose a mechanism for plasmid movement that does not rely on ParA polymerization.
