Genetic Variation of Hippeastrum Accessions in Vietnam

The present study was conducted to clarify the distribution and genetic diversity of Hippeastrum accessions cultivated in Vietnam. Twenty–five Hippeastrum accessions collected from 17 provinces in the northern, central, and southern regions of Vietnam were included. Results of floral observation and RAPD analysis indicate that there are four distinct groups of Hippeastrum being grown in Vietnam. These include cam dại (H. puniceum (Lam.) Kuntze syn. H. equestre Herbert), đỏ dại (H. x ‘Johnsonii’), đỏ cam dại (H. striatum Lamarck), and the hybrid cultivars. In the RAPD analysis result, 25 primers produced a total of 230 distinct bands, of which 167 were polymorphic (about 72.6%). The number of polymorphisms per primer ranged from 1 to 13, and one primer did not reveal any polymorphisms. Our phylogeny indicated four separate groups, with dissimilarity values ranging from 0.2 to 0.3 according to the phylogeny based on RAPD results. Some variation was observed between northern, central, and southern H. puniceum populations. Extensive variation in flower color, shape, and size was detected among accessions of the hybrid group. While H. puniceum is the most widely distributed species from the northern to the southern regions, H. x ‘Johnsonii’ has been observed only in the northern region, but not in the central or southern regions, so the distribution of Hippeastrum within Vietnam might depend on adaptation to environmental conditions. Our results have distinguished the đỏ dại and the cam dại groups, although a single scientific name has been applied to both extant groups in Vietnam. The present study is the first report on the presence and distribution of, and genetic variation among Hippeastrum accessions grown in Vietnam, which will be valuable information for Hippeastrum breeding programs.

A New Approach for Smoothing Soil Grain Size Curve Determined by Hydrometer

In hydrometer analysis for soil grain size distribution, usually, the grains passing sieve No. 200 (, there are big differences between the values of soil grain diameters smoothed by Excel-2007 in comparison and the values measured by references. These differences generally decrease with decreasing soil grain size diameters. The statistical treatments also divulge whether the hydrometer results are accurate or not. Furthermore, a general equation has been derived to estimate values of K factor, which is used for calculating the grain diameters in hydrometer analysis. The equation can be applied for any specific gravity of soils and for wide range temperatures.
Effect of nanoadditives on ionic conductivity of solid polymer electrolyte

Solid composite polymer electrolytes consisting of high molecular weight polyethylene oxide (PEO) with potassium iodide (KI) and sodium perchlorate (NaClO4) as electrolyte salts and cerium oxide (CeO2) and zirconium oxide (ZrO2) nanoparticles, respectively, as fillers have been prepared by standard solution cast technique. In the present work, PEO15-KI-CeO2 electrolytes have been prepared over a range of CeO2 content with particle size ~10 nm, whereas PEO25-NaClO4-ZrO2 electrolytes have been synthesized with various particle sizes of nano ZrO2 keeping the concentration constant to investigate the effect on the ionic conductivity.
Seed bank of an invasive alien, Heracleum mantegazzianum, and its seasonal dynamics

The seed bank of Heracleum mantegazzianum, native to the western Caucasus and invasive in Europe, was studied in the Slavkovský les Protected Landscape Area, the Czech Republic, during the course of two growing seasons. In each of seven study sites with dominating stands of the species, soil samples were taken in October (after the fruit release), April (before germination) and June–July (before the fruit release). Ten samples were taken from each site using a soil hand bore, 4.6 cm in diameter. Seeds elutriated from the samples were immediately germinated in laboratory conditions (10°C, 12 h light/12 h dark); those that germinated during 1 month were considered as non-dormant. Non-germinated but viable seeds, tested for viability by tetrazolium, were considered as dormant. The number of dead seeds was also recorded. The total number of seeds significantly increased with mean density of flowering plants at a site. Of the total variation in seed-bank size, about four-fifths were attributed to that among sites, and one-fifth to that within sites. The number and proportion of living seeds differed significantly between years in summer, but not in autumn and spring. Total number and the numbers of dormant, non-dormant, living and dead seeds significantly differed among the autumn, spring and summer samples. The percentage of living seeds in the total seed bank decreased from 56% in autumn to 42% in spring to 15% in summer. The percentage of non-dormant seeds among those living was 0.3% in autumn, it increased to 87.5% in the spring sample, and decreased to 3% in summer. Pooled across all sites, the average seed numbers (expressed per m2) were 6719±4119 (mean±SD) in autumn, 4907±2278 in spring and 1301±1036 in summer for the total number of seeds, and 3759±2906, 2044±1198 and 192±165, respectively, for living seeds. The majority of seeds (95%) were concentrated in the upper 5 cm soil layer. However, some seeds were present in lower soil layers, which indicates a short-term persistent seed bank. The present data are the first quantitative estimate of the seed bank in H. mantegazzianum, and show that the reproductive potential of the species is enormous, which seems to be a crucial feature of its invasion success.
A MIXED-SIGNAL MODEL DEVELOPMENT AND VERIFICATION METHODOLOGY WITH EMPHASIS ON A SIGMA-DELTA ANALOG-TO-DIGITAL CONVERTER

Mixed-signal ICs are ushering in an amazing era of Systems-on-a-Chip (SoC) ICs. The ever-increasing demand for feature rich consumer electronics coupled with decreasing device sizes open up limitless possibilities in Mixed-signal IC design. In this research we develop a methodology for comprehensive design and verification of a complex mixedsignal system using VHDL-AMS. We have described Sigma-Delta Analog to Digital Converter (SDADC) in VHDL-AMS, exploiting the advantages of modular design flow typical to VHDL, which helped in Top-Down design and Bottom-Up verification. We present an approach to develop, model, test and verify a mixed-signal system in VHDLAMS. The design and development were made possible by the continuous time simulator provided by Mentor Graphics in their latest SystemVision 4.2 Educational Version. The test scripts and experimentation methodologies are made generic to help in faster design and development of future mixed-signal models.
Hessian kernels of seismic data functionals based upon adjoint techniques

SUMMARY We present an extension of the adjoint method that allows us to compute the second derivatives of seismic data functionals with respect to Earth model parameters. This work is intended to serve as a technical prelude to the implementation of Newton-like optimization schemes and the development of quantitative resolution analyses in time-domain full seismic waveform inversion. The Hessian operator H applied to a model perturbation δm can be expressed in terms of four different wavefields. The forward field u excited by the regular source, the adjoint field u † excited by the adjoint source located at the receiver position, the scattered forward field δu and the scattered adjoint field δu † . The formalism naturally leads to the notion of Hessian kernels, which are the volumetric densities of H δm. The Hessian kernels appear as the superposition of (1) a first-order influence zone that represents the approximate Hessian, and (2) second-order influence zones that represent second-order scattering. To aid in the development of physical intuition we provide several examples of Hessian kernels for finite-frequency traveltime measurements on both surface and body waves. As expected, second-order scattering is efficient only when at least one of the model perturbations is located within the first Fresnel zone of the Fr´ echet kernel. Second-order effects from density heterogeneities are generally negligible in transmission tomography, provided that the Earth model is parameterized in terms of density and seismic wave speeds. With a realistic full waveform inversion for European upper-mantle structure, we demonstrate that significant differences can exist between the approximate Hessian and the full Hessian—despite the near-optimality of the tomographic model. These differences are largest for the off-diagonal elements, meaning that the approximate Hessian can lead to erroneous inferencesconcerningparametertrade-offs.ThefullHessian,incontrast,allowsustocorrectly account for the effect of non-linearity on model resolution.
Colostrum Protein Isolate Increases Gut and Whole Body Growth and Plasma IGF-I in Neonatal Pigs

The growth rate of the young pig is generally much less than it's potential and may be constrained by endocrine status as well as nutrient intake. Growth factors are present in relatively high quantities in colostrum and play an important part in gut development. It is possible that supplementation of colostrum protein isolate may stimulate gut and whole body growth in the pig. Eight male and 8 female (Large White×Landrace) piglets were weaned at 1 d of age after each pig had obtained colostrum from their dam, and were trained to consume one of two liquid diets. The two diets were based on either a colostrum protein isolate (n = 4 males and 4 females) or whey protein concentrate (n = 4 males and 4 females) and were formulated to contain equal levels of crude protein and amino acids. Pigs were fed their diets ad libitum for 28 days after which time 12 pigs were euthanised and various tissues and organs weighed. Pigs were bled for IGF-I analyses at 21 and 28 days of age. Daily gain was higher in pigs consuming the colostrum isolate (171 vs. 216 g/d, p = 0.010), particularly between 2 and 4 weeks of age (212 vs. 298 g/d, p = 0.010). Pigs tended to consume more of the liquid feed containing colostrum isolate (25.5 vs. 29.1 kg, p = 0.074) and gained more live weight per unit of liquid feed (0.203 vs. 0.223 g/g, p = 0.056). There were no effects of sex on growth performance. Pigs consuming the diet supplemented with colostrum isolate had higher (p<0.05) full gut weight (445 vs. 554 g, p = 0.026), empty gut weight (356 vs. 463 g, p = 0.008), stomach weight (42.2 vs. 54.4 g, p = 0.001), small intestine weight (222 vs. 275 g, p = 0.025) and large intestine weight (63.7 vs. 98.0 g, p = 0.005). Plasma IGF-I (99 vs. 150 ng/ml, p<0.001) and IGF-II (265 vs. 406 ng/ml, p<0.001) were higher in pigs fed colostrum isolate. Pigs consuming colostrum protein isolate ate more, grew faster and had higher plasma IGF-I concentrations than pigs consuming a diet with similar macronutrient
Identifying Effective Management Instruments and Human Behavioural Changes to Manage Energy Use and Abate Emissions at Firm Level

Despite recent efforts to reduce the growth of greenhouse gas emissions (GHGs) at the national level, the negative environmental impacts of GHGs are likely to increase more in the future, especially at the level of the company. This paper presents an extension to current integrated management efforts with traditional assessments to improve current situations. The extension can be used to determine strategies of cost-effectiveness to control emissions and achieve environmental goals in reducing concentrations of GHGs. Methods developed to demonstrate significant cost savings in companies and sectors are command and control (CAC), and innovation; these instruments can contribute to the allocation of emission controls when market instruments do not fully work. To achieve further GHG emission reductions, improvements to behavioural change regarding the use of energy are an emerging area of research that has significant implications for policy. There is increasing evidence that human behaviour has been producing environmental problems. This paper introduces elements and interventions that could affect that behaviour. Governments and businesses have agreed that there is a need for more emphasis on proper assessment of behavioural change interventions. Therefore, increasing efficiency and reducing barriers within marginal abatement cost curves (MACCs) has improved the results for the management of abatement energy and emissions at firm level.
The temporal and spatial scale of microevolution: fine-scale colour pattern variation in the Lake Erie watersnake, Nerodia sipedon insularum

Question: What is the temporal and spatial scale of microevolution? Hypotheses: The combined effects of natural selection and gene flow result in variation in heritable traits on fine spatial and geographic scales. Organism: The Lake Erie watersnake, Nerodia sipedon insularum. Field site: US and Canadian islands in western Lake Erie. Methods: We tested for variation in colour pattern frequency within islands, among islands, and over time using data from nearly annual censuses conducted since 1980, museum specimens, and published sources. We compared FST for a presumptive major colour pattern locus to FST for allozyme loci to determine whether spatial variation exceeded that expected by chance. We computed effective population size (Ne) based on temporal frequency changes in presumptive colour pattern alleles to determine whether temporal variation exceeded that expected by chance (Ne significantly less than ∞). Conclusions: Morph frequencies did not differ significantly within islands or between islands separated by short distances. Morph frequencies did sometimes differ significantly among distant islands and among sampling periods from 1980 to the present, but no more than expected by chance. In contrast, a marked change in morph frequency occurred between historic (prior to 1961) and recent (1980–2003) samples. Possible mechanisms include changes in the strength of selection (due to changes in predator assemblages and visual environments) and rates of gene flow (due to changes in island watersnake population size).
End User Computing Success Factors: Further Evidence from a Developing Nation

The rapid growth of end-user computing EUC has dramatically affected the nature of information systems in many organizations and many countries. EUC proliferation is more evident in organizations in developing countries because of steady improvement in the performance/price ratio of EUC computing technology. As organizations become increasingly dependent on EUC to fulfill their information requirements, the management of EUC resources demands a better understanding of the factors that affect EUC success. This paper attempts to measure and validate some individual and organizational factors hypothesized to affect the success of EUC in a developing country, namely Saudi Arabia. One hundred and fifty-eight end users in forty-five small organizations were surveyed. The study findings indicate that EUC success is closely associated with organization size, EUC training, source of computer application, computer literacy, top management involvement, number of system analysts, and availability of native language software. The need for a process oriented model to study organizational variables is addressed because of the importance of the time frame of the EUC adoption process.
The Relationship of Therapist Verbal Response Mode and Client Good Moments in Short Term Dynamic Psychotherapy

Using a single case quantitative analysis, the relation between therapist verbal response mode and client good moments was examined to provide information about the process of a short-term dynamic psychotherapy (STDP) developed by Davanloo (1978, 1980). Independent judges rated three sessions (early, middle and late) of a complete sixteen session treatment using the Hill Counselor Verbal Response Category System-Revised (HCVRCS-R) (Friedlander, 1982) and the Category System of Client Good Moments (CSCGM) (Mahrer, 1988). Chi-square analyses revealed a significant association between therapist verbal responses and the subsequent occurrence of client good moments. The results are discussed in terms of their clinical and research implications.
Development of Motion Detection Algorithms Based on Simultaneous Execution Using Mobile Phone Sensors

Abstract The proliferation of sensor networks employing wireless data transmission technologies has paved the way for the collection of large amounts of measurement data. Several research teams have used this opportunity to develop algorithms aimed at gaining information from sensor data. Motion detection is one of the most actively researched areas. In this article, we present a system for examining motion detection in a general environment. In other words, motion forms are not identified with various wearable sensors; instead, we use the data collected by the sensors of mobile phones kept with almost all members of society now.

Buerger’s disease-like arteritis associated with Crohn’s disease. A case of ‘vas-colitis’?

Crohn’s disease and ulcerative colitis are classified as inflammatory bowel diseases (IBD) [1]. Crohn’s disease is characterized by the involvement of the intestinal wall, which leads to the formation of ulcers, fistulas and strictures of the intestine. The disease is more frequently found among Caucasians. Parenteral manifestations are possible in the course of IBD, including osteoarticular and ocular manifestations, affecting the skin or the blood vessels. Only a few cases of the coexistence of Takayasu’s disease and IBD have been reported so far [2–5]. Takayasu’s disease is a chronic inflammation of the large-diameter vessels, which was described for the first time nearly two hundred years ago [6]. The incidence of Takayasu’s disease in the U.S. is estimated at about 2.6 cases per million. This condition, in contrast to IBD, is most common among young women of the Asian origin [7]. In this paper we discuss the case of the co-existence of Crohn’s disease and vasculitis, with symptoms and some angiographic features similar to Buerger’s disease, that was classified as vasculitis associated with systemic disease. So far, the available literature lacks descriptions of similar cases of Crohn’s disease associated with vasculitis mimicking Buerger’s disease.
Internal Friction Study of Vacancy Hardening in B2 Fe Al Alloys

nternal friction behaviour of B2 FeAl alloys has been examined to reveal the correlation of the microplasticity and thermal vacancies. The internal friction peak for Fe60Al40 appears at around 550 K, and the peak height increases with increasing quenching temperature. The curves of internal friction against the strain amplitude shift to larger strain amplitude as the quenching temperature increases. Analysis of the amplitude-dependent internal friction provides the plastic strain of the order of 10-9 as a function of effective stress on dislocation motion. It is found that the microflow stress at the plastic strain of 1×10-9 increases linearly with the square root of the net peak height. Remarkably, the microflow stress decreases with rising temperature but turns to increase above 500 K when measured after holding for 1 h at test temperatures. The anomalous increase in the microflow stress is caused by the creation of thermal vacancies at intermediate temperatures.
A new global burned area product for climate assessment of fire impacts

Aim This paper presents a new global burned area (BA) product developed within the framework of the European Space Agency's Climate Change Initiative (CCI) programme, along with a first assessment of its potentials for atmospheric and carbon cycle modelling. Innovation Methods are presented for generating a new global BA product, along with a comparison with existing BA products, in terms of BA extension, fire size and shapes and emissions derived from biomass burnings. Main conclusions Three years of the global BA product were produced, accounting for a total BA of between 360 and 380 Mha year-1. General omission and commission errors for BA were 0.76 and 0.64, but they decreased to 0.51 and 0.52, respectively, for sites with more than 10% BA. Intercomparison with other existing BA datasets found similar spatial and temporal trends, mainly with the BA included in the Global Fire Emissions Database (GFED4), although regional differences were found (particularly in the 2006 fires of eastern Europe). The simulated carbon emissions from biomass burning averaged 2.1 Pg C year-1
Lack of a centre effect in UK renal units: application of an artificial neural network model.

BACKGROUND Dialysis centre effect has been suggested to influence survival in end-stage renal disease (ESRD) patients. Few studies over the past decade have commented on the existence of the centre effect using logistic regression models. METHODS We used high quality prospectively collected data from the UK Renal Registry (UKRR) and created an artificial neural network model to predict mortality within 1 year in this cohort. We used a multitude of demographic variables including co-morbodities as well as relevant laboratory data to create a prognostic model. RESULTS A highly efficient model for predicting 1 year mortality was created after restricting the model to use demographic and case-enriched data [area under the receiver operating characteristic curve (AUROC) = 0.974]. The addition of the dialysis centre code and centre size as input variables did not add to the efficiency of the model (AUROC = 0.962). Moreover, dialysis centre code or size alone was not predictive of mortality when applied to an artificial neuronal network architecture (AUROC = 0.649 and 0.628). CONCLUSION Residual effects in previous studies may have been due to the non-linear nature of the data and complex intervariable relationships. Centre size and other centre-related factors have no impact on survival on ESRD.
