Stability and adaptability of seedcotton yields of upland cotton genotypes in the state of Minas Gerais, Brazil

Seedcotton yield of Gossypium hirsutum L. data from the regional cotton variety trials of the EPAMIG breeding program from 1990 to 1999 were analyzed with the objectives of: estimating both the magnitude of genotype by environment interactions and the genotype adaptability and stability according to the methods proposed by Eberhart and Russell, Lin and Binns and Annicchiarico; and selecting advanced lines to compose the final trials of the program. Four groups of genotypes and environments were assembled and analyzed. For the first one, significant genotype x year and genotype x location x year interactions were detected. The most stable genotypes were MG-864492 and IAC 20. Significant second-order interactions were estimated for the three remaining groups studied. In the second group the most stable strains were MG-863192 (according to Eberhart and Russell method) and MG-863579 (according to Lin & Binn’s and Annicchiarico’ s methods). For the third genotype-environment group, the most stable genotype under all methods was MG-864133. The cultivar EPAMIG 5 Precoce-1, in the fourth group, presented stable performance also under the three methodologies tested.
A Weather Generator for Use in Construction Simulation Models

In cold regions, weather poses uncertainty to construction projects. Project schedules can signif- icantly deviate from original plans. Management requires reliable plans and schedules to set project activity times and baseline schedules against which the project performance will be measured; with winter weather uncertainty in cold regions, this task becomes quite challenging. In this paper, a universal weather generator for use in construction simulation purposes is presented, with the detailed approach for generating each of the dierent suggested weather parameters. The universal weather generator has been developed and given param- eters for two cities in Alberta: Edmonton and Fort McMurray. The model parameters for both cities are given in order to facilitate future utilization of the model for academic and industrial research. To promote reusability and interoperability of the framework in future applications, the weather generator was developed using High Level Architecture (HLA), which showed great potential and suitability for this work.
The use of a lesion score as an indicator for agonistic behaviour in pigs

The aim of the present study was to analyse whether a lesion score approach could be used as an indicator for agonistic behaviour in pigs. Behavioural patterns were observed directly after weaning (PIG-28, n=827), 40 days later (growing pigs, PIG-68, n=292) and immediately after mixing gilts (GILTS, n=344), over a 48 h period. For the front, middle and rear part of the body the extent of skin injuries was assessed with a lesion score (LS). The LS ranked from 0 (no wounds) to 4 (many, deep wounds) and was determined at the beginning (LSstart) and at the end (LSend) of the observation period. In all groups, the front body third was mostly stressed by fighting interactions. The highest correlations were found between the front LS and the overall fight time, with r=0.50 (PIG-28), r=0.52 (PIG-68) and r=0.48 (GILTS). The LS for the front area did not increase for 26 % (PIG-28), 39 % (PIG-68) and 40 % (GILTS) of the animals. According to this, the applied LS approach only reflected the agonistic behaviour of pigs to a certain extent.
Nematode beta diversity on the continental slope of New Zealand: spatial patterns and environmental drivers

The management of marine biodiversity relies on sound knowledge of beta (or turnover) and gamma (or regional) diversity patterns, but such knowledge is largely lacking for continental slope environments. Here, we used free-living nematodes to investigate spatial and environmental patterns of beta and gamma diversity on 2 major seabed features of the New Zealand continental slope, Chatham Rise and Challenger Plateau. Species gamma diversity on Chatham Rise was about twice that observed on Challenger Plateau, which likely reflected the greater number of sites sampled and greater range of environmental conditions encompassed by our sampling on the former. Mean Bray-Curtis dissimilarity in community structure/composition (i.e. beta diversity) between Chatham Rise and Challenger Plateau, though high (>80%), was only marginally greater than within-region dissimilarity, and the beta diversity patterns we observed were mainly driven by factors acting at smaller (i.e. among-site) spatial scales. Sediment physico- chemical characteristics (i.e. microhabitat heterogeneity) were the main environmental driver of nematode species and genus beta diversity, and explained about a fifth of the variability. Spatial structure explained a similar proportion of species beta diversity, which, because our sampling strategy was designed to maximise the range of environments sampled across the study areas, may suggest an influence of environment at scales beyond that of the individual cores. A similarity profile test (SIMPROF) identified 9 sample groups based on species data, suggesting a relatively high level of heterogeneity on the open slope of New Zealand.
Flat photonic lattices for near-field imaging with enhanced depth of field

We numerically evaluated the 3D PSF of stratified negative-index superlenses. We determined in terms similar to the Rayleigh criterion the limit of resolution characterizing these image formers. Under some circumstances, the limit of resolution may drop approximately one order of magnitude. We investigated this significant increase of the resolution power in detriment of reducing the depth of field.
The Propensity Score method in public policy evaluation: a survey.

Recently, in the field of causal inference, nonparametric techniques, that use matching procedures based for example on the propensity score (Rosenbaum, Rubin, 1983), have received growing attention. In this paper we focus on propensity score methods, introduced by Rosenbaum and Rubin (1983). The key result underlying this methodology is that, given the ignorability assumption, treatment assignment and the potential outcomes are independent given the propensity score. Much of the work on propensity score analysis has focused on the case where the treatment is binary, but in many cases of interest the treatment takes on more than two values. In this article we examine an extension to the propensity score method, in a setting with a continuous treatment.
Scene Classification from Semantic Labeling

Finding an appropriate image representation is a crucial problem in robotics. This problem has been classically addressed by means of computer vision techniques, where local and global features are used. The selection or/and combination of different features is carried out taking into account repeatability and distinctiveness, but also the specific problem to solve. In this article, we propose the generation of image descriptors from general purpose semantic annotations. This approach has been evaluated as source of information for a scene classifier, and specifically using Clarifai as semantic annotation tool. The experimentation has been carried out using the ViDRILO toolbox as benchmark, which includes a companion of state-of-the-art global features and tools to make comparisons among them. According to the experimental results, the proposed descriptor performs similarly as well-known image descriptors based on global features in a scene classification task. Moreover, the proposed descriptor is based on generalist annotations without any type of problem-oriented parameter tuning.
Impact of Financial Contagion on Pension Portfolio’s Performance in Hungary and Russia

The composition of pension portfolio in emerging countries has several questions about the validity of portfolio building rules - which were standardized only on developed countries. Liquidity and distributional map of government bond markets are different in developed and emerging countries, which underline the importance of redefine the two possible - government bond and stock oriented patches - strategies in Central Eastern Europe. This paper compares yields of both simulated portfolios on an entire market cycle (between 2002 and 2009) to study fluctuations, cross correlations and the impact of extreme market events on each cases.
Development and Validation of Stability Indicating RP-HPLC Method for Simultaneous Estimation of Beclomethasone Dipropionate and Clotrimazole

The aim of the present study was to develop a validated stability indicating reverse phase high performance liquid chromatography (RP-HPLC) method for simultaneous estimation of Beclomethasone dipropionate (BEC) and Clotrimazole (CL) in bulk and combined dosage form ( CLOCIP-B cream). An isocratic, RP-HPLC method was developed using Hi Q Sil C18 (250 x 4.6 mm, 5 μm) column using 1 mM ammonium acetate buffer and acetonitritle (10:90 v/v) as mobile phase at flow rate of 1 ml/min at detection wavelength of 223 nm. The chromatographic conditions yield good separation between drugs with retention time (RT) of 4.227 ± 0.013 min and 6.440 ± 0.027 min, for BEC and CL, respectively. The method was validated with respect to linearity, precision, accuracy and robustness. The data of linear regression analysis indicated a good linear relationship over the range of 10-60 μg/ml for BEC and 5-30 μg/ml for CL concentrations with a correlation coefficient (r ) of 0.996 for BEC and 0.995 for CL. The drugs were subjected to forced degradation under different conditions. The developed method was found to be simple, sensitive, selective, accurate, and repeatable for simultaneous analysis of BEC and CL and can be adopted for routine analysis of these drugs in bulk and pharmaceutical dosage form.
Dynamic Task Prediction for an SpMT Architecture Based on Control Independence

An abstract of the thesis of Komal Jothi for the Master of Science in Electrical and Computer Engineering presented February 19, 2009. Title: Dynamic Task Prediction for an SpMT Arhitecture Based on Control Independence Exploiting better performance from computer programs translates to finding more instructions to execute in paralleL Since most general purpose programs are written in an imperatively sequential manner, closely lying instructions are always data dependent, making the designer look far ahead into the program for parallelism. This necessitates wider superscalar processors with larger instruction windows. But superscalars suffer from three key limItations, their inability to scale, sequential fetch bottleneck and high branch misprediction penalty. Recent studies indicate that current superscalars have reached the end of the road and designers will have to look for newer ideas to build computer processors. Speculative Multithreading (SpMT) is one of the most recent techniques to ex­ ploit parallelism from applications. Most SpMT architectures partition a sequential program into multiple threads (or tasks) that can be concurrently executed on mul­ tiple processing units. It is desirable that these tasks are sufficiently distant from each other so as to facilitate parallelism. It is also desirable that these tasks are control independent of each other so that execution of a future task is guaranteed in case of local control flow misspeculations. Some task prediction mechanisms rely on the compiler requiring recompilation of programs. Current dynamic mech­ anisms either rely on program constructs like loop iterations and function and loop boundaries, resulting in unbalanced loads, or predict tasks which are too short to be of use in an SpMT architecture. This thesis is the first proposal of a predic­ tor that dynamically predicts control independent tasks that are consistently wide apart, and executes them on a novel SpMT architecture.
The frequency of nasal septal deviation and concha bullosa and their relationship with maxillary sinusitis based on CBCT finding.

CBCT has facilitated the differential diagnosis due to the lower dose of radiation and higher resolution compared to CTscan. This study examines the frequency of deviated nasal septum, concha bullosa and their relationship with maxillary sinusitis based on CBCT findings. This study was conducted on 500 CBCTs cans performed in 2014-2016 using Sordex Scanora 3D (Helsinki, Finland). Two maxillofacial radiologists examined the scans in axial and coronal sections. The data analyzed using the Chi-square test and the t-test in SPSS-18. The patients mean age was 48.12±15.59 years, 27.6% had concha bullosa. There was a significant relationship between concha bullosa and gender (P=0.001) and also age (P=0.008) There were no significant relationships between nasal deviation and gender (P=0.64). No significant relationships were observed between nasal deviation and age (P=0.86) and also between maxillary sinusitis and age (P=0.503). A statistically significant relationship was observed between concha bullosa and nasal septal deviation (P<0.001). The statistical analyses showed no significant differences between septal deviation and maxillary sinusitis (P<0.001). presence of concha bullosa may be a risk factor for septal deviation as well as maxillary sinusitis. Although the presence of concha bullosa, maybe related to the patient’s age, in general, maxillary sinusitis is not significantly related to age and gender.
PREGLEDNI ČLANAK HEART RATE MODULATIONS IN OVERTRAINING SYNDROME

Every sports training program includes a component of repetitive overloading, but with an inadequate recovery time, such overloading may produce undesired eff ects, such as chronic fatigue and a lack of performance improvement. Th e state of underperformance known as the overtraining syndrome (OTS) is characterised by a number of physiological and psychological symptoms of maladaptation. It may take weeks, months or years to restore proper sports form after the development of OTS. Although overtraining has been studied for decades, the mechanism of overtraining and the tools for the early detection of overtraining are still not defi ned. In addition to other physiological, biochemical, immunological, psychological and performance markers, heart rate (HR) and its modulations are intensively investigated as a practical and reliable sign of overtraining. In general, resting bradycardia, a decrease in HR during submaximal exercise, an increase in speed of heart rate recovery and increased vagal-related heart rate variability indices are all well accepted markers of improved aerobic fi tness. In contrast, changes of these HR measures in the opposite direction are commonly interpreted as indicators of detraining, chronic fatigue, non-functional overreaching or overtraining. However, based on the limited and diverse literature available, these parameters may be used for monitoring training status, optimising training programs and following the accumulation of fatigue, but their role in overtraining detection and assessment has yet to be elucidated. Th ere is a need for well-controlled prospective studies where a longitudinal follow-up of athletes is performed. Because it is unethical to excessively train an athlete to produce OTS, an animal experimental model of OTS may advance our understanding of the “unexplained underperformance syndrome. ”
DIAGNOSTIC MODALITIES FOR EARLY RECTAL CANCER ! REVIEW OF THE LITERATURE

Rectal carcinoma represents a significant health problem in the modern world. Its high rate of occurrence and mortality in the late stages of the disease stresses the need for better diagnostic, prognostic and predictive methods. We present a review of the literature concerning the staging modalities, including the characteristics of early rectal carcinoma. Endoscopy, endoluminal ultrasound and magnetic resonance imaging play a major role in the preoperative staging and the restaging of rectal carcinoma. The new devices and technologies improve the diagnostic process thus providing an option for new management strategies and better results.
Minimum Change of “Shapes” of Molecular Orbitals in the Elementary Chemical Reactions and a New Perspective of Quantum Chemistry

Chemical substances are highly diverse. Here, we discuss the regularities of chemical changes among the substances. As a typical example, the regularity of the change between benzene and its structural isomers, i.e. Dewar benzene and prismane, has been discussed in terms of molecular vibrational theory and orbital correlation diagrams. It has been shown that when a certain molecule changes to another one with a similar structure, the “shapes” of the original electronic states are transferred to the next ones with minimum change. Regarding this, it has been pointed out that Neumann-Wigner’s non-crossing rule need not be applied to orbital correlation diagrams. It has also been shown that changes of molecules are “quantized” and cannot be described continuously, i.e. the states which can be accurately described by the Schrödinger equation are limited to “quantum steady states”.
Postharvest quality of tomato (Solanum lycopersicum) varieties grown under greenhouse and open field conditions

An experiment was carried out to evaluate performances of four tomato varieties (Bishola, Eshet, Marglobe and Moneymaker) harvested at ripe stage from greenhouse and open field condition at Jimma for post-harvest quality characters (total soluble solid, weight loss, titratable acidity, sugar-acid ratio, and pH). Bishola and Eshet had better chemical quality characteristics maintained throughout the end of the storage period. Varieties grown under open field condition showed highest fruit weight loss. The total soluble solid (TSS) values the open field grown tomatoes had highest than greenhouse grown tomatoes throughout storage period. The heighest TSS was obtained at 14 days storage while the lowest was at harvest. Titratable acidity of tomatoes after harvest tended to decrease throughout the storage period. Bishola had highest titratable acidity when compared with Eshet. There was increase in sugar/acid ratio throughout storage time for greenhouse growing condition, under open field condition there is a slight increment and rapid after harvest and then decrease at 14 days the storage period. This indicates that Greenhouse grown tomatoes have good flavor than open field grown. Tomato varieties grown under greenhouse condition were less weight loss, and higher sugar acid ratio and less prone to physical injuries than fruits of grown under open field condition. Variety Eshet and Bishola could be selected in maintaining better overall quality characteristics. Key words: Tomato, variety, storage period, greenhouse.
Single‐cell physiological structure and growth rates of heterotrophic bacteria in a temperate estuary (Waquoit Bay, Massachusetts)

Flow cytometric determinations of membrane integrity, nucleic acid content, and respiratory activity were combined with dilution cultures in Waquoit Bay Estuary (Massachusetts) to estimate specific growth rates of total, live, high (HNA), and low (LNA) nucleic acid content and actively respiring (CTC+) cells. Bacterial abundance ranged from 106 to 107 cells mL−1, with live cells generally contributing > 85% to total numbers, 42–82% HNA cells, and 3–36% CTC+ cells. Specific growth rates (µ) from all physiological groups were positively correlated, but they showed different temperature dependences, with activation energies ranging from 0.28 (live) to 0.97 eV (LNA). The µ values of live cells (0.14–2.40 d−1) were similar to those of total bacteria (0.06–1.53 d−1). LNA bacteria were not dormant but showed positive growth in most experiments, although HNA cells greatly outgrew LNA cells (µ ranges of 0.28–2.26 d−1 vs. 0–0.69 d−1), and CTC+ cells showed the highest values (0.12–2.65 d−1). Positive correlations of HNA bacteria µ with total and phytoplankton‐derived dissolved organic carbon support the previously hypothesized strong bottom‐up control of HNA cells. Bacterial production estimated from leucine incorporation and empirical conversion factors agreed well with estimates based on growth rates. HNA cells were always responsible for the largest share of bacterial production in the estuary. The contribution of CTC+ cells significantly increased with temperature in the 7–27°C range, reaching values of 40% at temperatures higher than 20°C.
The centre and periphery relations in international stock markets

Encouraged by the findings of the recent studies it is argued that a kind of centre-periphery relation has been emerging between the equity markets of the developed and less developed countries. To test the argument the VAR model is employed with block exogeneity. Empirical results show that S&P500 returns, representing the centre, affect the equity markets of the emerging markets either instantaneously or with a time lag depending on their geographical location.
Comparison study for forced convection heat transfer of supercritical carbon dioxide flowing in a pipe

Forced convection heat transfer in supercritical carbon dioxide (SCO2) was investigated experimentally in a horizontal circular tube with an inner diameter of 8.7 mm. The experiments were performed by varying the inlet fluid temperature, system pressure, wall heat flux, and mass flow rate. The corresponding Reynolds number at the inlet was between 20000 and 50000. Nusselt number at each section in the tube was obtained to investigate the influence of the experimental parameters on the forced convection heat transfer in the testing tube. The obtained heat transfer results were then compared with widely used empirical correlations to show their prediction accuracy for the experimental conditions tested.
