Influence of an iodine depletion period and teat dipping on the iodine concentration in serum and milk of cows

The objectives of the study were to investigate the influence of an iodine depletion period (from 10 to 0.2 mg Ι per kg dry matter, DM) on the iodine concentration of serum and milk and the effect of an iodized udder disinfectant solution on the iodine concentration of milk from dairy cows. Five late-lactating cows (milk performance: 22.1±2.0 kg per day) were used for the study. At the end of the dose-response study (up to 10 mg I supplementation per kg DM) without teat dipping, the basal diet (0.2 mg I/kg DM) was given for 16 days. The serum iodine concentration decreased from 290 to ≈ 60 μg kg-1 , that of milk, from 2762 to ≈ 100 μg kg-1. In the second part of the study the teats were separately dipped twice a day after milking in a disinfectant providing a free available iodine concentration of 3 g per l through nonoxinol(9)-iodine. The diet fed had a native iodine content of 0.2 mg/kg DM. Dipping was compared over 18 days with non-dipping. The dipping procedure significantly increased the mean iodine concentration from 100±23 to 154±42 μg kg-1 milk.
The Effect of Lock-Ups on the Suggested Real Estate Portfolio Weight

We test relative illiquidity, exemplified through a temporary lock-up, as a partial explanation for the gap between theoretical and empirical weights for real estate in a multi-asset portfolio. Since asset correlations are known to increase in bear markets, which reduce their diversification benefits, the ex-ante knowledge of a lock-up in an asset class that offers diversification benefits in bull markets (Hung et al., 2008) may reduce the optimal weight that an investor wishes to put in it ex-ante. By using dynamic multiperiod portfolio policies by Brandt and Santa-Clara (2006), and introducing a lock-up in line as per de Roon et al. (2009), we study the effects of a partial lock-up on the weight for REITs in a U.S. stock and bond portfolio. We find support for our prediction, in the form of lower weights for the illiquid asset once a lock-up is introduced.
Marine radiocarbon reservoir age simulations for the past 50,000 years

Radiocarbon (14C) dating calibration for the last glacial period largely relies on cross‐dated marine 14C records. However, marine reservoirs are isotopically depleted with respect to the atmosphere and therefore have to be corrected by the Marine Radiocarbon Ages of surface waters (MRAs), whose temporal variabilities are largely unknown. Here we present simulations of the spatial and temporal variability in MRAs using a three‐dimensional ocean circulation model covering the past 50,000 years. Our simulations are compared to reconstructions of past surface ocean Δ14C. Running the model with different climatic boundary conditions, we find that low‐latitude to midlatitude MRAs have varied between 400 and 1200 14C years, with values of about 780 14C years at the Last Glacial Maximum. Reservoir ages exceeding 2000 14C years are simulated in the polar oceans. Our simulation results can be used as first‐order approximation of the MRA variability in future radiocarbon calibration efforts.
Clinical Decision Support Systems Continuance: Integrating Physicians’ Professional Identity with Delone & McLean IS Success Model

Despite the importance of sustained and continued use of healthcare information systems to reap their benefits of cost reductions and quality improvements, research on continuance use of these systems is limited. In this paper, we study physicians’ continuance to use a pain management clinical decision support system by developing a theoretical model that integrates Delone and McLean IS success model with physicians’ professional identity constructs, an integration that addresses the gap of separating information systems constructs from physicians’ idiosyncrasies constructs in extant literature. We conduct our study through a mixed methods longitudinal design that addresses our research questions. This study enhances our understanding of factors influencing physicians’ continuance behavior and extends current literature on healthcare information systems use
Effect of Energy Substrate Dynamics on Mitochondrial Activity and Oxidative Stress Levels of in vitro Maturing Bovine Oocytes

This study was conducted to explore the effect of energy substrates in the culture medium during in vitro maturation of bovine oocytes. A modified TCM199 medium (M-7528) was used to mature bovine oocytes in vitro . Oocytes were supplemented with different pyruvate (0.1, 0.2, 0.4 mM) and glucose (1.5, 5.6, 20.0 mM) concentrations for 48 hours at 38.5 °C under 5% CO 2 atmosphere with 95% humidity. Their maturity was checked at 24 and 48 hours. After 48 hours, the denuded oocytes were stained with fluorescent dye JC-1 and avidin-FITC. Fluorescent dye JC-1 is a membrane permeable to the cell and would indicates membrane activity or its organization. Fluorescence intensity of avidin-FITC determination using corrected total cell fluorescence (CTCF) expressed oxidative stress level. There is a significant contribution of energy substrates towards oocyte maturation. Pyruvate at 0.2 mM produced mature oocytes with a diameter of ≥ 120 μm, promoted oocytes maturation to metaphase II (MII) stage faster and reduced cell’s oxidative stress levels. In comparison, 5.6 mM glucose is the optimum concentration for glucose to reduce cell stress level. Unfortunately, this concentration only produced mature oocytes with a small diameter of up to 116 μm. All changes were significant at the level of p < 0.05. As a conclusion, pyruvate at 0.2 mM is the optimum concentration for in vitro maturation after taking cell’s stress level into consideration.
METABOLIC ADAPTATION STRATEGY USING Zymomonas mobilis CP4 CELLS FOR THE PRODUCTION OF SECOND GENERATION ETHANOL

During the past few decades, considerable effort has been made to utilize agricultural and forest residues as biomass feedstock for the production of bioethanol as an alternative fuel. The bacterium Zymomonas mobilis was shown to be extremely attractive for the production of second-generation ethanol from glucose of the cellulose fraction due to its ability to uptake high amounts of this sugar, resulting in high ethanol productivity values. However, the wild-type strains are unable to metabolize xylose that arises from the hemicellulose fraction. Molecular biology techniques were incorporated to render the strain used in this study capable of fermenting xylose into ethanol and thus increase the efficiency of second-generation ethanol production. Thus, the aim of this study was to evaluate the performance of a recombinant strain of Z. mobilis in simultaneous saccharification and co-fermentation (SSCF) processes, in which the fermentation of both sugars (glucose and xylose) occurs in one step. Regarding the genetic transformation,the 1,565 kb Z. mobilis plasmid pZMO1 was chemically synthesized and cloned into a synthetic vector that contains the E. coli and Z. mobilis replication checkmark origin,the XI, XK, TAL, and TKL genes and tetracycline resistance. Metabolic adaptation was performed by transferring the recombinant strain to media containing increased xylose concentrations. Then, an experimental response surface methodology was used to evaluatethe addition of glucose and xylose with different concentrations, as well as the incorporation of hemicellulosic hydrolyzate in different proportions. The recombinant Z. mobilis CP4 strain reached 25 g/L ethanol, confirming that approximately 50% of this pentose was consumed in the SSCF process when using 30% solids, 20.5% hemicellulose hydrolysate, 10 mg/L tetracycline, an enzyme load of 25 FPU/g cellulignin, and 10% of the initial inoculum.
Getting emotional: measuring effect of camera angle in context by means of emotions

This study explored the effects of vertical camera angle (high/low) and negative comment (dangerous/incompetent) on characteristics attributed to and emotions elicited by a stimulus photograph. Based on embodiment theory and supported by Frijda’s (2005) emotion experience theories, results were acquired through semantic differentials and use of the SAM and the PrEmo. In addition to effects of vertical camera angle and comment, more extreme effects were expected of interactions between the two. On the SAM and the PrEmo, no effects of vertical camera angle and comment were found. On the semantic differentials, no effect of camera angle was found, but the dangerous comment was judged more ‘bad’, more potent and more active than the incompetent comment. All tools found interaction of camera angle and comment, with the high angle/dangerous comment combination leading to higher scores on the semantic differentials and the SAM. On the PrEmo, the high angle/dangerous comment and the low angle/incompetent comment led to higher scores.
A TRI-BAND-NOTCHED UWB PLANAR MONOPOLE ANTENNA USING DGS AND SEMI ARC-SHAPED SLOT FOR WIMAX/WLAN/X-BAND REJECTION

In this paper, a novel monopole printed fork-shaped antenna for ultra-wideband (UWB) applications with triple band-notched characteristics is presented. The proposed antenna, with compact size of 42 × 24 × 1.6 mm3, yields an impedance bandwidth of 3.1–11 GHz for S11 < −10 dB, except on the notched bands which are obtained by introducing three different types of slots. A U-shaped and two extended U-shaped defected ground structure (DGS) slots give respectively two notched bands, 3.3 to 3.7 GHz for WiMAX and 7.1 to 7.76 GHz for downlink X-band satellite communication systems. Therefore, a semi arc-shaped slot is etched on the radiating patch to notch the band from 5.15 to 5.825 GHz for WLAN applications. The proposed antenna is fabricated and measured.
Development of in vitro Chylomicron Assay Using Caco-2 Cells

Development of in vitro Chylomicron Assay Using Caco-2 Cells by Yuxi Sun Dietary fats are mainly transported by the intestine in lipoproteins: chylomicrons (CMs) and very low density lipoproteins (VLDLs). Unfortunately, studies of the intestinal absorption of dietary fat have been hampered by the lack of an adequate in vitro model system. As an in vitro model Caco-2 cells are able to secrete lipoproteins. We investigated the possible factors that may affect the secretion of CMs through the ultracentrifugation technique. The dose-dependent effects of oleic acid, mono-olein, egg lecithin, collagen matrix, and the effect of cell differentiation on CM secretion were then tested. We found that oleic acid, lecithin, and cell differentiation are critical for CM secretion by Caco-2 cells. To further confirm that our optimal condition is, in fact, favorable for efficient CM production, we compared it with control groups. We observed that our condition led to more efficient CM secretion as determined by the TGs, ApoB, and TEM analysis.

This research investigates the impact of remittances on financial development of Pakistan. Overseas remittances have positive and major relation with GDP of Pakistan at the same time as inflation and exchange rate has unconstructive effect on economic growth. The multiple regression investigation is used to identify the relationship between the dependent and independent variables. In this study, we considered economic growth as the dependent variable. For independent variables worker’s remittances, foreign direct investment, inflation, and exchange rate and agriculture growth.
On Tractable Markov Random Field Models and MapReduce Algorithms: Towards a Practitioner's Toolbox

In the era of big data, data sets have been growing very large, and interest for algorithms and computation framework that handle such large scales is increasing. The number of computing cores per chip has also increased. Instead of developing ingenious ways of speeding up convergences and obtaining better approximations for a smaller subclass of the problems, it is interesting to simply “throw more cores” at exact algorithms and get a speed-up which scales accordingly. This allows practitioners who are not specialists to use the algorithms more efficiently. The MapReduce framework is one of the most widely used paradigms for parallel computation, and we show how to cast the exact deterministic algorithms for our customized spatial model in this framework. Abstract. Higher-order Markov random fields, i.e., Markov random fields with higher-order interactions, have been shown to be able to represent large-scale properties of typical spatial scenes via MCMC simulation. We present a Markov random field parametrization such that the specification of clique configurations that include higher-order interactions is included in a methodical fashion. This ought to be useful for a practitioner with respect to specifying the type of images desired. The general Markov random field model commonly requires approximation techniques due to its intractable normalization constant, and inference and simulation techniques for models with high dependence via MCMC tend to be time-consuming and may involve algorithms with sensitive convergence criteria. These algorithms are not suitable for practitioners or spatial modellers who are not well-versed in MCMC, and it is therefore more desirable for them to work with models that are able to reproduce spatial structures, while still being easier to wield. We construct variants of the Markov random field that seek to achieve the same goal, but whose inference and simulation is tractable without MCMC, and cast the latter in the MapReduce framework. We also consider the MapReduce formulation of MCMC simulation algorithms for Markov random fields in order to leverage the power of parallel computing.
An outbreak of malignant catarrhal fever in Murrah buffaloes in Minas Gerais, Brazil

An outbreak of Malignant Catarrhal Fever (MCF) resulted in death of five female buffaloes and one domestic cow from the same farm. Four buffaloes died 10-15 days after the appearance of clinical signs, while the fifth was euthanized in extremis, after similar clinical signs. Histopathological lesions included multifocal histiolymphocytic epicarditis, myocarditis and lymphocytic interstitial pneumonia, which are commonly seen in cases of MCF in buffaloes. Furthermore, lymphocytic vasculitis centered in the adventitia, with occasional fibrinoid necrosis in the muscular layer, was found in the kidneys, liver, spleen, lymph nodes and brain. Nucleotide sequencing of DNA fragments from the central nervous system amplified by PCR revealed 98% similarity with known OHV-2 sequences from Genbank. Additionally, PCR analysis also revealed the presence of OHV-2 DNA in the peripheral mononuclear blood cells of two clinically healthy buffaloes. The diagnosis of MCFwas based on epidemiological, clinical, gross and histopathological findings and on the results of a semi-nested PCR followed by nucleotide sequencing.
The behavioral Inhibition system in childhood and adolescent anxiety: an analysis from the information processing perspective

Iedereen kent wel kinderen met een angstig temperament: kinderen die snel schrikken, moeilijk te troosten zijn, of verlegen en teruggetrokken zijn. De meesten van die kinderen groeien daar uit. Anderen blijven angstig en bang. Sommigen krijgen zelfs last van echte angststoornissen, die hen hinderen in hun dagelijks leven. Leentje Vervoort onderzocht het verband tussen een angstig temperament en angststoornissen. Ze deed dat door te kijken naar de manier waarop kinderen met en zonder angstproblemen omgaan met informatie uit de buitenwereld. Vervoort concludeert dat kinderen met een angststoornis sneller hun bezigheden staken dan kinderen zonder angstproblemen wanneer ze geconfronteerd worden met enge dingen. Daarnaast vond ze dat kinderen met een angststoornis enge dingen beduidend negatiever evalueren dan kinderen zonder angststoornissen De laatste groep vindt enge dingen niet negatiever dan gewoon negatieve dingen. Ten slotte keek Vervoort hoe de aandacht voor enge dingen verschilt tussen kinderen met en zonder angstproblemen. Hoewel vaak gedacht wordt dat temperament iets is wat we niet kunnen veranderen, lijkt het er toch op dat kinderen met een angstig temperament ‘beschermd' kunnen worden tegen angstproblemen door de manier waarop kinderen omgaan met informatie uit de buitenwereld aan te pakken.
The distance sum rule from strong lensing systems and quasars – test of cosmic curvature and beyond

Testing the distance-sum-rule in strong lensing systems provides an interesting method to determine the curvature parameter $\Omega_k$ using more local objects. In this paper, we apply this method to a quite recent data set of strong lensing systems in combination with intermediate-luminosity quasars calibrated as standard rulers. In the framework of three types of lens models extensively used in strong lensing studies (SIS model, power-law spherical model, and extended power-law lens model), we show that the assumed lens model has a considerable impact on the cosmic curvature constraint, which is found to be compatible or marginally compatible with the flat case (depending on the lens model adopted). Analysis of low, intermediate and high-mass sub-samples defined according to the lens velocity dispersion demonstrates that, although it is not reasonable to characterize all lenses with a uniform model, such division has little impact on cosmic curvature inferred. Finally, thinking about future when massive surveys will provide their yields, we simulated a mock catalog of strong lensing systems expected to be seen by the LSST, together with a realistic catalog of quasars. We found that with about 16000 such systems, combined with the distance information provided by 500 compact milliarcsecond radio sources seen in future radio astronomical surveys, one would be able to constrain the cosmic curvature with an accuracy of $\Delta \Omega_k\simeq 10^{-3}$, which is comparable to the precision of \textit{Planck} 2015 results.
Isolation and characterization of amylase from fermented cassava ( Manihot esculenta Crantz ) waste-water

The processing of cassava tubers for the production of nutrient enriched cassava flour, gari and farinha madioca, is usually accompanied with the production of stinking wastewater which usually constitute nuisance to both terrestrial and aquatic life. Thus, this study sought to assess the potential utilization of the wastewater as a source of industrial amylase. Wastewater from cassava mash fermented with pure strains of Saccharomyces cerevisae together with Lactobacillus delbruckii and Lactobacillus coryneformis for 3 days was assayed for amylase activity. The result of the study indicated that the fermentation wastewater had amylase activity, the unit activity and the specific activity of the amylase in the wastewater was 0.22 μmole/min and 0.06 μmole/min/mg, respectively. The amylase was purified using gel filtration (SephadexG150). The purified enzyme was maximally active at pH 6.0 and 60°C temperature. It had is maximum stability between pH 6 – 7 for 4 h, and 30°C for 50 min. NaCl, NH4Cl, FeCl3, KCl, NaNO3 activates the enzyme activity while CuSO4 and HgCl2 inhibit the activity of the amylase. It could therefore be concluded that these amylases from the fermented cassava waste water are active at wide temperature and pH ranges. This quality could be explored in the industrial sector (most especially food industry) as a source of industrial amylase that require a wide range of conditions (temperature and pH).
EFFECT OF A SINGLE ORAL ADMINISTRATION OF IRON FUMARATE ON HAEMATOLOGICAL INDICES AND ANTIOXIDANT STATUS IN PIGLETS

The aim of this study was to evaluate the efficiency of a single oral iron fumarate administration, and to compare antioxidant status of piglets treated either orally or parenterally. Two days after birth, the piglets in group I (22 piglets) were orally given 200 mg of Fe 2+ as iron fumarate. At the same time, the piglets in group II (21 piglets) were given intramuscularly 200 mg of Fe 3+ as iron dextran. The piglets in group III (18 piglets), were given intramuscularly 200 mg of Fe 3+ at the age of 28 d. At the age of 21 and 28 d Hb, PCV, MCV, MCH and iron concentration in blood plasma of group I were significantly lower compared to group II. No differences in antioxidant status (vitamin E, GSH-Px, total antioxidant capacity) were observed between groups I and II. For group III, on day 28, GSH-Px activity (expressed per 1 T/l RBC) was significantly lower compared to group II. It is concluded that single oral administration of iron fumarate is insufficient for the prevention of iron deficiency and that either parenteral or oral administration do not reduce the antioxidant status of the piglets.
The implementation of ERP systems in Iranian manufacturing SMEs

The quest to implement Enterprise Resource Planning (ERP) software to support all main business functions has been actively pursued by in-house IT departments, software vendors and third party consultancies for over three decades. It remains a key element of many companies’ information systems strategy in the developed world, and increasingly, in the developing world. In the specific context of Iranian SMEs, there has been relatively little research on information systems in general, and very little specifically on ERP systems projects. This paper attempts to help address this dearth in the existing literature by examining three case studies of ERP systems deployment in Iranian manufacturing SMEs. It investigates the underlying information systems strategies and examines how this has been implemented in the core process areas of these companies. The analysis is based on a conceptual model that combines defined implementation phases with change dimensions and elements, which provide the basis for the development of an implementation framework for subsequent ERP projects in this business and technology environment.
Cross-cultural study of accounting students' perception of accounting ethics in Iran and United Kingdom

Accountants faces a lot of challenges because of their positions and if they want to achieve society trusts, should regard a series of ethical. Accountants would be able to play their role properly by recognizing some ethical rules and principles because of increasing globalization of economics in international scandal and not community ones. In this research, we compare accounting students' perception of accounting ethics in Iran and United Kingdom using Accounting-specific Defining Issues test (ADIT) and Accounting-specific Multidimensional Ethics scales (AMES). Results of the study indicate that accounting students in United Kingdom are in higher levels of ethical perceptions. In this study, Kohlberg's ethical-cognitive development theory, Rest's four components model and Hofstede’s 5 dimensions of culture have been considered as the theoretical basis. Key words: Ethical development, ethical sensitivity, ethical orientation, ethical intention, ethical perception, culture.
POD-DEIM APPROACH ON DIMENSION REDUCTION OF A MULTI-SPECIES HOST-PARASITOID SYSTEM

In this study, we implement the DEIM algorithm (Discrete Empirical Interpolation Method), combined with POD (Proper Orthogonal Decomposition) to provide dimension reduction of a model describing the aggregative response of parasitoids to hosts in a coupled multi-species system. The model is defined by five reaction-diffusionchemotaxis equations. We show DEIM improves the efficiency of the POD approximation and achieves a complexity reduction of the nonlinear terms. Numerical results are presented. MSC: 35K57, 65M06, 65Y20. keywords: reduced order modeling, proper orthogonal decomposition, discrete empirical interpolation method.
