Screening of teff (Eragrostis tef) varieties for genotypic and phenotypic traits in Dejen Woreda, East Gojjam Zone

Twenty-four teff varieties obtained from DebreZiet Agricultural Research Center were evaluated for agronomic traits such as days to emergence, days to heading, days to maturity, grain filling period, plant height, panicle length, shoot biomass, straw yield and grain yield in a randomized complete block design, at Dejen Woredain 2015/16 cropping season. The analysis of variance showed that the varieties had significant variation (p<0.01) for days to heading, days to maturity, grain filling period, plant height, shoot biomass, straw yield and grain yield. However, the varieties did not show significant variation for days to emergence and panicle length. It was observed that varieties were significantly different from each other in plant height. Dz-01-3186 (Etsub, 103.06cm) and DZ-01-1681(kayt-ena) (99.73 cm) showed greatest height as compared to other varieties whereas SR-RIL-273(Laketch) (80.46 cm) was the shortest in plant height. Similarly for grain yield per plot, Dz-01-3186 (Etsub) (28.1 qt/ha), Dz-01-2053 (Holeta Key) (24.48 qt/ha) and DZ-01-99 (Asgori) (22.6 qt/ha) were showed significant superiority of yield per plot over the other varieties. Significant variation was observed for straw yield among varieties. Superior performance was observed by varieties Dz-01-3186 (Etsub) (112.8 qt/ha), Dz-01-2053 (holeta key) (105.1 qt/ha) and DZ-01-99 (Asgori) (103.2 qt/ha). Dz-Cr-385 RIL295 (Simada) had the longest grain filling period which was 66.33 days. DZ-Cr-44 (Menagasha) took 114 days to mature. The highest heritability value was observed for days to heading (69.77%) and plant height (49.43%). Days to heading, days to maturity, shoot biomass, plant height, panicle length and lodging index showed positive correlation with grain yield. Shoot biomass (0.81) and plant height (0.66) showed strong significant positive correlation (P < 0.001) with grain yield. It can be summarized that farmers of Dejen district get an access for high yielding varieties Dz-01-3186 (Etsub), Dz-01-2053 (Holeta Key) and DZ-01-99 (Asgori) which would be recommended for better productivity and production of teff. Key words: Teff, genotypic, phenotypic, heritability, genetic advance, correlation.
Gas-liquid slug formation at a rectangular microchannel T-junction: A CFD benchmark case

Computational fluid dynamics (CFD) is an important tool for development of microfluidic systems based on gasliquid two-phase flow. The formation of Taylor slugs at microchannel T-junctions has been studied both experimentally and numerically, however discrepancies still exist because of difficulties in correctly representing experimental conditions and uncertainties in the physics controlling slug flow, such as contact line and velocity slip. In this paper detailed methods and results are described for the study of Santos and Kawaji [1] on the comparison of experimental results and numerical modeling. The system studied consisted of a rectangular microchannel Tjunction nominally 100 μm in hydraulic diameter, used to generate Taylor slugs from air-water perpendicular flow. The effect of flow rates on parameters such as slug length, velocity slip, void fraction and two-phase frictional pressure drop were studied. Numerical simulation was performed using FLUENT volume-of-fluid (VOF) model. It is proposed in this paper that this microfluidic problem be taken up by researchers in the field as a benchmark case to test other numeric codes in comparison to FLUENT on the prediction of micro-scale multiphase flow, and also to model in more detail the experimental system described to obtain greater accuracy in prediction of microfluidic slug formation.
THE ROLE MODEL EFFECT IN HIGHER EDUCATION by JESSICA BOULWARE

This report provides review of the existing literature on the role model effect in higher education and identifies the methodological and conceptual issues that have complicated the research program before discussing how research on similar areas may provide insight into the relationship between female students and female faculty members. By examining the related literature on the determinants of college major, peer effects, and critical mass theory, the existing studies of role model effect can be interpreted as support for a more specified theory of the role model effect in higher education that highlights the importance of the gender composition of the course or field of study.
LHCb tracking, alignment and physics performance

The LHCb experiment at the LHC is designed for precision heavy flavour physics. Its tracking, alignment and physics performance is discussed with focus on the silicon strip detectors. First results of the tracking efficiency measured with collision data are presented as well as single hit, impact parameter and vertex resolutions. The tracking efficiency is above 95% for all tracks with a transverse momentum above 100 MeV/c which covers the full physics range. The single hit resolution of the VErtex LOcator (VELO) sensors for tracks of optimal incidence is better than 4 μm for a strip pitch of 40 μm. The impact parameter resolution is found to be about 30 μm for tracks with 3 GeV/c transverse momentum. The status of the spatial detector alignment is described before discussing the proper time reconstruction performance.
Organic–Inorganic Mesoporous Silica Nanotube Hybrid Anodic Alumina Membranes for Ultrafine Filtration of Noble Metal Nanoparticles

Novel metal nanoparticles (NPs), such as gold (Au), platinum (Pt), palladium (Pd), and silver (Ag) have gained increased attention due to their distinctive physical and chemical properties as well as effective applications in catalysis, imaging, gene expression, chemical sensing, biolabeling, disease diagnostics, disease therapeutics, nanoscale electronics, and photonics. The physical and chemical properties as well as potential applications of these NPs are strongly dependent on their shapes, sizes, and structural geometries. However, conventional synthesis methods produce novel metal NPs with broad size distributions and uncontrollable precise morphologies. Therefore, it is necessary to develop a simple, effective, and fast method for separating NPs with different sizes and shapes.
Fat Tail Model for Simulating Test Systems in Multiperiod Unit Commitment

This paper describes the use of Chambers-Mallows-Stuck method for simulating stable random variables in the generation of test systems for economic analysis in power systems. A study that focused on generating test electrical systems through fat tail model for unit commitment problem in electrical power systems is presented. Usually, the instances of test systems in Unit Commitment are generated using normal distribution, but in this work, simulations data are based on a new method. For simulating, we used three original systems to obtain the demand behavior and thermal production costs. The estimation of stable parameters for the simulation of stable random variables was based on three generally accepted methods: (a) regression, (b) quantiles, and (c) maximum likelihood, choosing one that has the best fit of the tails of the distribution. Numerical results illustrate the applicability of the proposed method by solving several unit commitment problems.

Electro-Pneumatic Servo System

A predictive pneumatic circuit, able to harness to provide power to a variety of mechanisms or machines depending upon their application, has been proposed. With the emergence of the pneumatic-servo system, pneumatic system control is extended from logical control to servo control area. The model can be used as a tool to assess apriori the operations of turbines, manufacturing and other related industries and can be easily coupled to kinetic models for process simulation. The input parameters to the model include the air pressure inside the compressor and the type and magnitude of voltage provided to the double solenoid servo valve. The model has been successfully verified and tested with satisfactory results. The model output, to successfully provide the actuating force to a piston, is assessed critically. The proposed circuit, if used, can be pivotal in transforming typical hydraulic circuits into their pneumatic counterparts. Pneumatic systems can be connected with hoses, pipes or tubing without difficulty, producing a large amount of linear energy. Using pneumatic systems is economical and environmental friendly, as air is inexpensive, plentiful and easily compressed and stored in tanks.

Automated experiment design for drug development

Testing drugs in discovery is time consuming and expensive. An idea is then to eliminate unpromising compounds from the testing phase by using online learning methods to predict properties of yet to be tested compounds and determining which drugs to test. This is done by comparing substructures in the graph representation of compounds, transformed into a compressed high dimensional space where a Gaussian process bandit and a linear bandit is used to predict properties of new compounds. Results show that the bandits perform signi cantly better than random selection and that the feature compression probably does not decrease the overall accuracy of the predictions.
Response of O 2 and pH to ENSO in the California Current System in a high-resolution global climate model

Abstract. Coastal upwelling systems, such as the California Current System (CalCS), naturally experience a wide range of O 2 concentrations and pH values due to the seasonality of upwelling. Nonetheless, changes in the El Nino–Southern Oscillation (ENSO) have been shown to measurably affect the biogeochemical and physical properties of coastal upwelling regions. In this study, we use a novel, high-resolution global climate model (GFDL-ESM2.6) to investigate the influence of warm and cold ENSO events on variations in the O 2 concentration and the pH of the CalCS coastal waters. An assessment of the CalCS response to six El Nino and seven La Nina events in ESM2.6 reveals significant variations in the response between events. However, these variations overlay a consistent physical and biogeochemical (O 2 and pH) response in the composite mean. Focusing on the mean response, our results demonstrate that O 2 and pH are affected rather differently in the euphotic zone above ∼ 100 m . The strongest O 2 response reaches up to several hundreds of kilometers offshore, whereas the pH signal occurs only within a ∼ 100 km wide band along the coast. By splitting the changes in O 2 and pH into individual physical and biogeochemical components that are affected by ENSO variability, we found that O 2 variability in the surface ocean is primarily driven by changes in surface temperature that affect the O 2 solubility. In contrast, surface pH changes are predominantly driven by changes in dissolved inorganic carbon (DIC), which in turn is affected by upwelling, explaining the confined nature of the pH signal close to the coast. Below ∼ 100 m , we find conditions with anomalously low O 2 and pH, and by extension also anomalously low aragonite saturation, during La Nina. This result is consistent with findings from previous studies and highlights the stress that the CalCS ecosystem could periodically undergo in addition to impacts due to climate change.
The Brazilian AMS Radiocarbon Laboratory (LAC-UFF) and the Intercomparison of Results with CENA and UGAMS

After 22 yr of the low-level liquid scintillation counting 14C laboratory at the Center for Nuclear Energy in Agriculture (CENA) at São Paulo University (USP), Piracicaba, Brazil, and several collaborative projects with Brazilian and international researchers from distinct scientific areas, the first 14C accelerator mass spectrometry (AMS) laboratory in Latin America was installed at the Physics Institute of the Universidade Federal Fluminense (UFF), Niterói, Brazil. A 250kV single stage accelerator produced by National Electrostatics Corporation began its operation in 2012. In this work, we compare measurements performed at the AMS Radiocarbon Laboratory at UFF (LAC-UFF) with those performed at CENA and the University of Georgia (UGAMS), Georgia, USA. All the results obtained from distinct inorganic and organic samples were in very good agreement.
Molecular cloning of a novel GSK3/shaggy-like gene from Triticum monococcum L. and its expression in response to salt, drought and other abiotic stresses

The glycogen synthase kinase 3 (GSK3)/SHAGGY-like kinases are nonreceptor serine/threonine protein kinases that are involved in a variety of biological processes. Here, a novel GSK-3-like kinase encoding cDNA was isolated from Triticum monococcum L. seedlings by reverse transcriptase polymerase chain reaction (RT-PCR). Sequence analysis showed that the full length of cDNA consist of 1,543 bp with an open reading frame of 1,068 bp, which encodes 355 amino acid residues. The deduced amino acid sequence showed a high homology with shaggy-like kinases from Triticum aestivum, Zea mays, Trifolium repens, Nicotine tabacum, Medicago sativa and Arabidopsis thaliana; therefore, the gene was named TmGSK1 (Triticum monococcum Glycogen Synthase Kinase 1,GenBank Accession No. DQ443471). Southern blot analysis indicated that there was only one copy of TmGSK1 in the einkorn wheat genome. Quantitative real-time RT-PCR studies showed that the expression of TmGSK1 in the einkorn wheat was induced by salt stress, mechanical wounding, ABA hormone, cold and drought. These results suggest that cells accumulate more TmGSK1 mRNA response to those abiotic stresses. TmGSK1 was shown to be a positive regulator commonly involved in the tolerance to salt, mechanical injury, ABA hormone, cold and drought in einkorn wheat.

Uganda’s equilibrium real exchange rate and its implications for non-traditional export performance

Pursuit of an exchange rate policy that promotes the competitiveness of exports would be greatly facilitated if the policy maker were able to establish the level of misalignment of the exchange rate and thereby try to correct for it. The motivation of this study for Uganda was therefore to derive the equilibrium exchange rate path, determine the levels of misalignment of the exchange rate and assess their impact on the performance of nontraditional exports. Estimating the equilibrium real exchange rate (ERER) involved: (a) estimation of the real effective exchange rate (REER) by the cointegration and the error correction mechanism (ECM) approaches, (b) filtering transitory factors from the "fundamentals" using the Hodrick-Prescott filter approach and the Elbadawi moving average (MA) methodology, and (c) estimating the ERER using the permanent components of the fundamentals. We find that the magnitude of misalignment, derived as the deviation of REER from ERER, greatly reduced during the period 1991-1999, when the exchange and payments system was liberalized as part of the overall improved macroeconomic management. Further, given that over-valuation of the exchange rate in excess of 15% hampers non-traditional export performance, our results suggest that the exchange rate policy should aim at minimizing over-valuation and, in fact, albeit the inflation objective, over-depreciate REER to boost non-traditional export competitiveness. An explicit estimate of the equilibrium exchange rate is therefore an important variable in exchange rate policy and export competitiveness debates.
Estimating the gravity equation with the actual number of exporting firms

To estimate correctly the effect of variable trade costs on firms' exports, the gravity equation should control for the number of firms that participate in foreign markets. Due to the absence of these data, previous studies control for this omitted variable using econometric strategies that may also lead to inconsistent estimations. To overcome this problem the present paper estimates a gravity equation using a new database compiled by the OECD and Eurostat that reports the number of exporting firms by reporter and partner country. We show that no controlling for the extensive margin of trade introduces very serious biases in the estimated trade cost coefficients. Moreover, these biases are much larger than predicted by previous studies.
Association of the body types and disease-related values of knee osteoarthritic patients

Different spa therapy courses are offered for treating knee osteoarthritis (OA) in Estonian medical spas. They contain approximately six daily sessions of three different treatments: massages, thermotherapies, kinesitherapies etc. There are some disease related risk factors including weight and sex. All subjects in the current study were divided into five height-weight classes and they were evaluated before and after the spa therapy course and the follow-up after 10 weeks and six months. To assess the clinical status different questionnaires (HAQ-DI, VAS, Lequesne Index) were used. The results showed that the subjects who participated in the study were mainly females and overweight. In the female group, there were more big type persons, but males were more leptomorphic. Females reported greater knee pain values, but males felt much better after six months. Also, leptomorphs had significantly better changes in the follow-up study. Higher pain diminishing was found in overweight persons but not obese subjects. The subject’s functional ability to do usual activities was mild or moderate. Only leptomorphs had significant decrease in the follow-up study. The Lequesne Index related to the function of the knee and score stabilized after 10 weeks in the small and leptomorph group.
Modeling hydrological controls on variations in peat water content, water table depth, and surface energy exchange of a boreal western Canadian fen peatland

Improved predictive capacity of hydrology and surface energy exchange is critical for conserving boreal peatland carbon sequestration under drier and warmer climates. We represented basic processes for water and O2 transport and their effects on ecosystem water, energy, carbon, and nutrient cycling in a process‐based model ecosys to simulate effects of seasonal and interannual variations in hydrology on peat water content, water table depth (WTD), and surface energy exchange of a Western Canadian fen peatland. Substituting a van Genuchten model (VGM) for a modified Campbell model (MCM) in ecosys enabled a significantly better simulation of peat moisture retention as indicated by higher modeled versus measured R2 and Willmot's index (d) with VGM (R2~0.7, d~0.8) than with MCM (R2~0.25, d~0.35) for daily peat water contents from a wetter year 2004 to a drier year 2009. With the improved peat moisture simulation, ecosys modeled hourly WTD and energy fluxes reasonably well (modeled versus measured R2: WTD ~0.6, net radiation ~0.99, sensible heat >0.8, and latent heat >0.85). Gradually declining ratios of precipitation to evapotranspiration and of lateral recharge to discharge enabled simulation of a gradual drawdown of growing season WTD and a consequent peat drying from 2004 to 2009. When WTD fell below a threshold of ~0.35 m below the hollow surface, intense drying of mosses in ecosys caused a simulated reduction in evapotranspiration and an increase in Bowen ratio during late growing season that were consistent with measurements. Hence, using appropriate water desorption curve coupled with vertical‐lateral hydraulic schemes is vital to accurately simulate peatland hydrology and energy balance.
