Effect of L-carnitine on reproductive performance and fry performance of Nile tilapia broodstock

L-carnitine feed additive can be applied in different fish species for improving reproductive performance due to effect on energy utilization. This study aimed to investigate the effect of L-carnitine on reproductive performance and fry performance of Nile tilapia Oreochromis niloticus broodstock. Females (48) and males (24) of Nile tilapia broodstock were fed commercial pelleted diet (35% crude protein (CP), 4586 Kcalkg -1 diet Gross Energy (GE) supplemented with different concentrations of L-carnitine (0.0, 300 and 500 mgkg -1 diet) for 105 days feeding trail in 6 breeding hapas (2x2x1m 3 )with feeding rate 2% then offspring's collected to study reproductive performance. For fry feeding in nursery hapas. A commercial powder diet (40.50 % CP and 4897 GE Kcalkg -1 diet) were fed for 60 days. The diet was fed at rate 10% of the total fry biomass at the first 30 days started from the 2 nd day of collecting fry from the broodstock (spawning) hapas and decreased to 5 % in the 2 nd growth interval which extended for 30 days. Results indicated that a significant improvement in seeds production with 500 mgkg -1 L-carnitine. The data also indicated that the inclusion of L-carnitine in tilapia broodstock diets have a beneficial effect on growth performance, energy utilization with no significant effect on body chemical composition of Nile tilapia fry.
Modal Sound Field Decomposition Applicable for a Limited Range of Directions

The decomposition of spatial sound scenes using spherical microphone arrays is usually based on spherical harmonics. However, the decomposition in spherical harmonics requires a distribution of microphones covering all directions, even if all sources are not all around. For a restricted range of directions the spherical harmonics can be orthogonalized, yielding the spherical Slepian functions. These are well-suited to interpolate data on a partial spherical domain. However, they introduce large errors when extrapolating sound fields with sources outside the restricted range. A different set of orthogonal functions is obtained by solving the Helmholtz equation with an angular boundary condition, e.g. a directional range delimited by an infinite cone that acoustically excludes sources outside. This article discusses the characteristics of the corresponding spherical cap/segment harmonics compared to the spherical harmonics and Slepian functions applied to holographic sound field extrapolation.
An Improved Adjusted Plus-Minus Statistic for NHL Players

The plus-minus statistic for NHL players is meant to be a measure of a player's offensive and defensive abilities. However, a player's plus-minus is highly dependent on the team he plays for, the opponents he faces, and other variables out of his control, so it is not always a good measure of that player's individual contribution to his team. In this paper we develop an adjusted plus-minus statistic that attempts to isolate a player's individual contribution. Using data from the detailed shift reports on NHL.com, we develop two weighted least squares regression models to estimate an NHL player's effect on his team's success in scoring and preventing goals, independent of that player's teammates and opponents. Our initial work focused on even strength situations, excluding situations in which one team had pulled their goalie. In our current work, we have modeled power play and shorthanded situations, and we are able to estimate a player's offensive and defensive contributions during those situations. Also, for those shifts that begin with a faceoff, we have accounted for the zone on the ice in which a shift begins.
Effects of Pre-sowing Treatments and Sowing Depths on Germination of Rain tree ( Albizia saman ) : A Step towards Conservation of Albizia

The study was carried out in Federal College of Forestry Mechanisation, Afaka, Kaduna, to investigate means of enhancing the germination of Albizia saman seeds which has a very low germination rate under normal conditions and also to draw steps to be taken from the findings towards conservation. The experiment on the effect of temperatures of water (27, 50, 73 and 96C) and sowing depths (1, 2, 3 and 4cm) was combined in 4x4 factorial experimental designs. A 3x3 factorial design was employed in combining the effect of sulphuric acid treatment durations (10, 30 and 60 minutes) and volumes of acid (20, 30 and 50ml) on the germination of A. saman seeds in second experiment. Germination percentages of seeds soaked in 27, 50, 73 and 96C water ranged between 32.71-45.46%. Highest germination percentage value of 45.46% was recorded for seeds treated in 96C water. The result of interactive effect of water temperatures and sowing depths on the germination of A. saman seeds ranged between 31.11-50.77%. Highest germination percentage value of 50.77% was recorded for seeds treated in 96C water and planted in 1cm sowing depth. Germination percentages of seeds treated for 10, 30 and60 minutes ranged between 65.88-71.56%. Highest germination percentage value of 71.56% was recorded for seeds treated for 30 minutes. Germination percentages of seeds treated for 10, 30 and 60 minutes and soaked in 20, 30 and 60ml of acid ranged between 63.44-90%. Highest germination percentage value of 90% was recorded for seeds treated for 30 minutes in 20ml of acid. The research therefore recommends soaking of A. saman seeds for 30 minutes in 20ml of acid for mass production of its seedlings for conservation in agro-forestry systems.
Recent Changes in Intergenerational Mobility in Britain December 2007

This report investigates recent changes in social m obility by considering relationships between intermediate outcomes (degree attainment, t st scores and non-cognitive abilities) and parental income for cohorts born bet we n 1970 and 2000. There is no evidence that these relationships have changed in a co sistent way over this period. This is in stark contrast with the strengthening relatio nship between intermediate outcomes and parental income that accompanied the previously we l documented decline in social mobility that occurred for birth cohorts from 1958 and 1970. Our findings suggest that the decline in intergenerational mobility that occu rred between these cohorts is not ongoing, but neither has there been any significant improvement. Acknowledgements We would like to thank Lee Elliot Major and Peter L ampl for a number of helpful comments and Richard Murphy for his assistance in c oding and cleaning the income data for the 1970 cohort in 2004 and the Millennium Coho rt Study.
Economic considerations for using sexed semen on Holstein cows and heifers in Estonia

The study investigated economic and managerial considerations for using sexed semen as a tool for accelerated herd expansion and improvement of its genetic potential. Economic value of reproduction strategies based on conventional semen and sexed semen were analysed according to partial budgeting method by Victor E Cabrera and adjusted for the Estonian average indicators. Data for the study were provided by Animal Breeders Association of Estonia. In order to evaluate the economic value of using sexed semen over conventional semen, five different reproductive strategies involving sexed semen were used and compared with conventional semenbased strategy. Average conception rate from the first insemination with conventional semen was 65.6% and 56.1% with sexed semen for Holstein heifers in Estonia in 2015. Probability for birth of a female calf was 49.3% with conventional semen and 93.0% with sexed semen. Net present value for all sexed semen based reproduction strategies was negative at the baseline conditions. Sensitivity analysis for key reproductive and economic variables showed that market price of female calves and conception rates had the most impact on the economic value. Sexed semen can be a valuable tool for reproduction management in dairy farms, but the actual economic value of its application depends on the reproductive performance and objectives of an individual farm. Results of this study provide basis for further research about the situations, where using sexed semen would be economically justified for the farmers.
CD 301 b + Macrophages Are Essential for Effective Skin Wound Healing

Regeneration of skin’s barrier function after injury requires temporally coordinated cellular interactions between multiple cell types. Macrophages are essential inflammatory cells in skin wound regeneration. These cells switch their phenotype from inflammatory in the early regenerative stages to anti-inflammatory in the midstages of healing to coordinate skin repair. However, little is known about how different subsets of anti-inflammatory macrophages contribute to skin wound healing. Here, we characterize midstage macrophages (CD45+/CD11b+/F4-80+) and identify two major populations: CD206+/CD301b+ and CD206+/CD301b−. The numbers of CD206+/CD301b+ macrophages increased concomitantly with repair, when the anti-inflammatory phenotype switch occurs in midstage healing. Using diphtheria toxin–mediated depletion models in mice, we show that selective depletion of midstage CD301b-expressing macrophages phenocopied wound healing defects observed in mice where multiple myeloid lineages are depleted. Additionally, when FACS-isolated subpopulations of myeloid cells were transplanted into 3-day wounds of syngeneic mice, only CD206+/CD301b+ macrophages significantly increased proliferation and fibroblast repopulation. These data show that the CD301b-expressing subpopulation of macrophages is critical for activation of reparative processes during the midstage of cutaneous repair.
The Value Relevance of Accounting Fraud and Discretionary Accruals

The objective of this study is to analyze the value relevance of accounting fraud and discretionary accruals (positive and negative discretionary accruals) in French context during the period 2006-2010. Using the model of Ohlson (1995) which test the price and return model, we note that the price model provides a more significant result on the value relevance than the return model. In addition, fraud has a more significant and negative effect than discretionary accruals and even dilutes its existence in the price and return model. This finding proves the signals theory that bad information transferred quickly in the stock market.
ANÁLISE DE COOCORRÊNCIAS DE ANOMALIAS E PADRÕES DE PROJETO EM SISTEMAS DE SOFTWARE

Software systems are often developed in a way that good practices of the object-oriented paradigm are not fulfilled, causing the occurrence of bad smells. Bad smells are symptoms or structural characteristics in a region of code that may suggest the presence of a deeper problem in the system design or code. On the other hand, design patterns are intended to catalog the best practices for developing object-oriented software systems. Although apparently widely divergent, there may be a co-occurrence of design patterns and bad smells, since this phenomenon is sometimes cited in studies in the software engineering field, albeit discreetly. Therefore, this dissertation performs an exploratory analysis in order to identify the co-occurrence of design patterns and bad smells in software systems, that may happen due to the inadequate use of design patterns. To achieve this goal, we first perform a literature review in order to understand the current state of art concerning design patterns and bad smells and, then, we accomplish an exploratory study to identify concrete instances of design patterns inadequate usage that lead to bad smells occurrences. In this study, we use tools for detecting design patterns and bad smells in five medium to large size systems. The study results indicate interesting co-occurrences, as Command with God Class and Template Method with Duplicated Code. We analyse why these patterns provoked the bad smells arising. We also discuss the severity of bad smells and, when appropriate, propose changes to the system code in order to address the detected bad smells. These findings indicate that, although design patterns catalog the best practices for developing software systems, their inadequate use may have undesired effects.

THE VALUE OF MOMENTUM TO ACTIVE MANAGERS AND PLANNED SPONSORS IN AUSTRALIA

1 We would like to thank Dr Katharina Schwaiger for useful advice on the Australian market, an anonymous referee for many helpful comments, and Maurice Peat (the editor) for encouraging us to research in this area. 2 We investigated the July effect in Australia with data up to 2018 but found little evidence of its continued existence. However, this was with an index constructed of large stocks only, and not following the formation procedures of Durand et al. (2006). In this paper we present some details of momentum investment hopefully of interest to fund managers and planned sponsors. The focus will be on momentum investment in Australia, but much of the discussion, and results, are applicable virtually everywhere. The academic literature considers many different types of momentum strategies, and we distinguish between academic and institutional momentum investment in section 2. In section 3, we discuss linkages between investor behaviour and momentum. We present information about the pattern of returns one might expect and market conditions that might help or hinder performance in section 4. Apart from being a style of investment, quantitative financial analysts (quants) also think of momentum as a factor; we shall discuss this briefly in section 5. We present some results in section 6 together with conclusions. Andrew Grant, Senior Lecturer, University of Sydney Business School

Challenges and Solutions in Acoustical Measurements and Design : Paper ICA 2016-325 A discussion on the uncertainty of absorption characteristics measured by ensemble averaging technique for room acoustics simulations

The authors proposed an in-situ sound absorption measurement method using an ensemble averaging technique, EA metod, for short. Herein, EA method measurements are conducted nine times repeatedly with three pressure-velocity sensors (Microflow; pu-sensor) to prove the effect of sensor difference on resulting sound absorption coefficients and to examine if the uncertainty stays within such a small range as is suitable for room acoustics simulations. EA method conducted here follows the configuration given in our earlier papers and sound absorption coefficients of a glass-wool board, a needle felt sheet and a slice form sheet were measured. To prove the effect of pusensor difference on the resulting sound absorption coefficient three pu-sensors were employed. The sensors were calibrated using an acoustic tube with a diameter of 10 cm just before or after a series of measurement. The results of nine times measurement of the glasswool board showed slight differences only at 100 Hz, 500 Hz and 1250 Hz and uncertainties (standard deviation) of sound absorption coefficient stay less than 0.02. The results of the other two materials are rather in better agreements with less uncertainty. The measurement results of sound absorption coefficient obtained using the three pu-sensors showed good agreements each other for the three materials. The maximum difference 0.04 is observed for the glass-wool board at 1250 Hz. Such larger differences are observed at both limits of the frequency range of the acoustic tube used for pu-sensor calibration. Except the frequencies, uncertainties of sound absorption coefficients measured by EA method with different three pu-sensors stayed the values within suitable range for room acoustics simulations.
Revision 1 1 Micro and nano-characterization of Zn-clays in nonsulfide supergene ores of 2 southern Peru 3 4

12 Zn-clays are associated with several supergene nonsulfide ore deposits worldwide, where they are 13 either the prevailing economic minerals, or minor components of the weathering-derived mineral 14 assemblage. A TEM-HRTEM study on Zn-clays from nonsulfide ore deposits of Accha and Yanque 15 (Peru) was carried out, to properly specify the chemistry and complex texture of these clays, not fully 16 determined in other previous works on these (but also on other similar) deposits. The Zn-clays 17 occurring at Accha and Yanque are constituted by a mixture of sauconite and Zn-bearing beidellite. 18 Here we report the first worldwide occurrence of Zn-bearing dioctahedral smectite (beidellite). 19 Chemical formulas of sauconite and beidellite have been also established. The chemical composition of 20 sauconite varies in a range of values, without any chemical gap, around the average composition: 21 Ca0.15K0. 05(Zn2.1Mg0.2Al0.4Fe0.15Mn0.02)(Si3.5,Al0.5)O10(OH)2·nH2O. 22 Beidellites present a composition close to stoichiometry with the addition of Zn: 23 Ca0.05K0. 15(Al1.6Zn0.25Mg0.1Fe0.15)(Si3.6Al0.4)O10(OH)2·nH2O. 24
Abundance of Arthropods of Medical Importance in Nipa Invaded Wetlands of Eastern Obolo , Nigeria

Arthropods abound in every conceivable environment. From December 2016 to May 2017, a survey was conducted to determine the abundance of arthropods of medical importance in nipa invaded wetlands of Eastern Obolo, Nigeria. Both aquatic and terrestrial habitats of the study area were surveyed. A scoop net was used for the collection of aquatic specimens, while a sweep net and various traps (pit fall, light and sticky traps) were used for terrestrial investigations. A total of 1094 arthropod from the classes crustacea, Arachnida and Insecta were collected. Out of the 1094 arthropods collected only 308 were of medical importance. These were Callinectes Amnicola (blue crabs) of the class crustacea, ixodid ticks (12.01%) of the class Arachnida and some insect vectors. Insect vectors collected included Periplaneta americana (4.22%) of the order Blattodea and dipterans of the families Phlebotomidae (40.26%), Ceratopogonidae (22.10%), Muscidae (16.23%) and Culicidae (4.87%). Results obtained from t-test revealed that the seasonal variation in abundance of the medically important arthropods was significant as t-tabulated (2.13) was less than t-tabulated (3.99). Shannon Wiener’s diversity index (H) revealed that the terrestrial habit was more diverse (3.22) than the aquatic habitat (1.32). White flies of the species Trialeurodes vaporariorum were also collected. These are alien species which have been introduced into the environment because of invasion by nipa palm. However, they are not of medical importance. Since some medically important arthropods have been identified in the study area, it is pertinent to draw up a program targeted at the control of these vectors and hence the prevention of vector-borne disease outbreak. This will enhance the quality of health and livelihood of the community dwellers.
The Impact of Time on Product-Harm Crises in the Food Industry : The Case of IKEA ’ s Meatballs

The current paper focuses on the recent crisis concerning the firm IKEA (meatball samples after analysis were found to include horsemeat) and examines the impact of time on consumers’ impression of the company, perceived danger, blame, perceived severity, anger and purchase intentions. Since previous studies have demonstrated that time diminishes the negative effects of a product-harm crisis, the paper aims at investigating the variations of the aforementioned variables in five different time periods after the crisis. Results showed that consumers were quite reluctant towards eating at IKEA’s restaurant a few days after the incident, but within the next ten weeks perceived danger had already been reduced and consumers felt that eating meatballs at the restaurant was pretty safe. Although the company did not follow a high accommodative crisis management strategy (i.e. issue an apology along with a straightforward explanation), it seems that consumers “forget” after a certain period of time and their purchase behavior returns to its normal pattern.

DYNAMICS OF SEED GERMINATION , SEEDLING GROWTH AND PHYSIOLOGICAL RESPONSES OF SWEET CORN UNDER PEG-INDUCED WATER STRESS

Stress induced variations in seed germination of various crops has been well reported but germination potential of sweet corn seeds under osmotic stress with relation to time dynamics is still elusive. Present study explored the water absorption, germination potential and physiological indices and of sweet corn seeds exposed to five different levels of PEGinduced water stress i.e., 0, 0.3, 0.6, 0.9 and 1.2 M Pa water potential (w) with respect to time dynamics. Results showed that enhanced water stress for prolonged time period (96 h) led to substantial reduction in water absorption and seed moisture contents, seed germination and vigor index as well as seedlings growth and fresh and dry biomass. Osmotic stress triggered antioxidant defense system like super-oxide dismutase (SOD), peroxidase (POD) and catalase (CAT) and accumulation of soluble sugars, proline and protein contents considerably. Initially, activities of SOD and CAT were higher but then reduced as stress persisted, however, POD showed a linear increase with respect to stress exposure time. Water stress also increased MDA contents up to 36 h then declined. Further, α-amylase activity and soluble protein showed significant correlations with maize seed germination. Overall, germination potential decreased with increase in osmotic stress in sweet corn seeds.
Asset Pricing When Traders Sell Extreme Winners

This study investigates the asset pricing implications of a newly documented refinement of the disposition effect, characterized by investors being more likely to sell a security when the magnitude of their gains or losses on it increases. I find that stocks with both large unrealized gains and large unrealized losses outperform others in the following month (trading strategy monthly alpha = 0.5–1%, Sharpe ratio = 1.5). This supports the conjecture that these stocks experience higher selling pressure, leading to lower current prices and higher future returns. Overall, this study provides new evidence that investors’ trading behavior can aggregate to affect equilibrium price dynamics. (JEL G11, G12, G14)
Arching Behind Retaining Walls under Active Translation Mode : Review and New Insights

Granular materials have a tendency to exhibit an arching effect by which the load is transferred from yielding parts to adjacent stationary parts. Retaining walls are among those structures that the soil arching plays an important role in the distribution of earth pressures. This paper reviews briefly the development of soil arching theory and its application to different geotechnical projects. Various arching-based theoretical formulations for estimation of lateral active earth pressure on the rigid retaining walls were reviewed and their validity was examined through comparisons with the field data. It was concluded that, in spite of the conventional thought that the distribution of lateral earth pressure on the walls is linear, it is non-linear due to soil arching. Moreover, the maximum lateral stress does not appear at the toe of the wall; but it appears at some heights, leading to a shift of the point of application of thrust from 33% to approximately 40% of the wall height measured from the bottom of the wall.
