EFFECT OF DIFFERENT AMINO ACIDS AT DIFFERENT CON-CENTRATIONS ON MULTIPLICATION AND ROOTING STAGE OF In vitro PROPAGATION OF STRAWBERRIES (Fragaria X Ananassa Duch cv. Chandler)

The Present study was carried out for the purpose of enhancing strawberries (Fragaria X Ananassa Duch cv. Chandler) via In vitro regeneration. Since amino acid compounds provide a vital role in plant tissue culturing, this study was conducted for the purpose of identifying the optimum conditions and concentrations from three selected amino acid compounds. Tyrosine, Arginine, and Glutamine were added at different concentrations (0, 25 50 and 100 mg/L), separately and supplemented with standard MS nutrient culture medium. The results demonstrated that tyrosine at (25 mg/L) significantly promoted the shooting and rooting growths as well as the acclimatization stage (in vivo) development. Supplementation of the MS culture medium with arginine and/or glutamine at the assessed concentrations yielded results that were much better than the control culture nutrient medium for the induction of the shooting and rooting stages providing healthy plantlets.
Toward a Model of Retention and Persistence for Black Men at Historically Black Colleges and Universities (HBCUs)

A frequent theme in the literature on historically Black colleges and universities (HBCUs) is their supportive and nurturing environment. Despite the consistency of this theme, less research has provided context about some of the contemporary experiences of Black men at HBCUs. This information is critical because many Black colleges, much like their predominantly White institutional counterparts, have high Black male attrition rates. This article seeks to help Black colleges reduce attrition among Black males by using empirical literature specifically focused on Black men at HBCUs to inform a model of retention and persistence for this student demographic. In addition to fully contextualizing the model, this article concludes by discussing implications for future research on Black men at HBCUs.
An overview of interactions among oceanography, marine ecosystems, climatic and human disruptions along the eastern margins of the Pacific Ocean

Los procesos fisicos y biologicos y las actividades humanas determinan los ecosistemas marinos. El manejo futuro de estos valiosos ecosistemas requiere de una aproximacion integrativa que considere las complejas interacciones entre individuos, los procesos oceanograficos que se desarrollan a gran escala espacial y temporal, y la interaccion de los efectos antropogenicos con el medio ambiente. Las costas templadas del oeste de Norteamerica y Sudamerica representan una oportunidad unica para efectuar comparaciones ya que muchos procesos oceanograficos, particularmente la surgencia costera, ocurren en ambas costas. Adicionalmente, numerosos ecosistemas marinos en ambas areas presentan sorprendentes paralelos. La presente revision ofrece una vision general de los procesos oceanograficos dominantes en ambas costas y ofrece ejemplos de ecosistemas y los efectos que la oceanografia, las actividades humanas y las interacciones entre individuos tienen sobre las comunidades marinas
Assessment of the Teaching Methods that Influence the Acquisition of Practical Skills

This study is designed to identify the teaching methods that influence the acquisition of practical skills of mechanical engineering trades students at technical college level using regression analysis. Descriptive survey research design was utilized in carrying out the study. Ninety nine (99) mechanical engineering trades’ teachers and fourty six (46) administrators in the technical colleges in north central states of Nigeria responded to a structured questionnaire which addressed the research question. Cronbach Alpha coefficient was used in determining the reliability of the instrument. The reliability co-efficient of the instrument used for data collection stood at 0.78. It was recommended that mechanical engineering trades teachers and administrators in the schools be encouraged to use different instructional methods, especially the methods identified in the study as the most significant determinants of the teaching methods that influence the acquisition of practical, so that the students can acquire the skills for gainful employment in the labor market or be able to establish on their own and become self-reliant.
The effect of nitrogen fertilizer form and foliar application on the concentrations of twenty-five elements in carrot

Abstract Among all elements taken into consideration in this research (Al, As, B, Ba, Be, Bi, Ca, Co, Cr, Fe, Ga, In, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, Ti and V), only the concentration of Na in the ‘Kazan F1’ carrot was affected by the interaction of foliar application and nitrogen fertilization. In the case of plants fertilized by Ca(NO3)2, foliar application significantly raised Na concentration in storage roots. Compared to the control, all applied nitrogen fertilizers (results analysed independently from the foliar application factor) increased concentrations of Mg and Se in carrot. Fertilization with (NH4)2SO4 resulted in a decrease of Ba and Mo concentrations and an increase of Mn concentration, while fertilization with Ca(NO3)2 raised the contents of Sr and Be in carrot. Foliar application (analysed independently from nitrogen fertilization) considerably increased Bi and Be concentrations, yet it did not affect the contents of other elements in storage roots.
Seismic attenuation in Faroe Islands basalts

We analysed vertical seismic profiling (VSP) data from two boreholes at Glyvursnes and Vestmanna on the island of Streymoy, Faroe Islands, to determine the magnitude and causes of seismic attenuation in sequences of basalt flows. The work is part of SeiFaBa, a major project integrating data from vertical and offset VSP, surface seismic surveys, core samples and wireline log data from the two boreholes. Values of effective seismic quality factor (Q) obtained at Glyvursnes and Vestmanna are sufficiently low to significantly degrade the quality of a surface reflection seismic image. This observation is consistent with results from other VSP experiments in the North Atlantic region. We demonstrate that the most likely cause of the low values of effective Q at Glyvursnes and Vestmanna is a combination of 1D scattering and intrinsic attenuation due to seismic wave‐induced fluid flow within pores and micro‐cracks. Tests involving 3D elastic wave numerical modelling with a hypothetical basalt model based on field observations, indicate that little scattering attenuation is caused by lateral variations in basalt structure.
Zero-Viscosity Limit of the Navier-Stokes Equations with the Navier Friction Boundary Condition

In this paper, we consider the zero-viscosity limit of the Navier-Stokes equations in a half space with the Navier friction boundary condition $$ (\beta u^{\varepsilon}-\varepsilon^{\gamma}\partial_y u^{\varepsilon})|_{y=0}=0, $$ where $\beta$ is a constant and $\gamma\in (0,1]$. In the case of $\gamma=1$, the convergence to the Euler equations and the Prandtl equation with the Robin boundary condition is justified for the analytic data. In the case of $\gamma\in (0,1)$, the convergence to the Euler equations and the linearized Prandtl equation is justified for the data in the Gevrey class $\frac 1 {\gamma}$.
Deep Learning for the Segmentation of Vessels in Retinal Fundus images and its Interpretation

The main goal of this dissertation is to study and analyze different approaches based on deep learning techniques for the segmentation of retinal blood vessels. In order to do so, different design and architectures of CNN's will be studied and analysed, as their results and performance are evaluated and compared with the available algorithms. One other important objective of this work is to study and evaluate the different techniques that have been used for vessel segmentation, such as machine learning, and how these can be combined with the deep learning approaches. By Analyzing the features that the learned models are using to perform classification and combining them with different machine learning techniques (such as Random Forest and SVM Classifiers), another goal is to proposed a solution or set of solutions to perform the retinal vessel segmentation.
Implicit and Explicit Stigma of Mental Illness: Attitudes in an Evidence-Based Practice

Abstract The extent to which explicit and implicit stigma are endorsed by mental health practitioners using evidence-based practices is unknown. The purposes of the current study were to a) examine implicit and explicit biases among Assertive Community Treatment (ACT) staff and b) explore the extent to which biases predicted the use of treatment control mechanisms. Participants were 154 ACT staff from nine states. Overall, the participants exhibited positive explicit and implicit attitudes toward people with mental illness. When modeled using latent factors, greater implicit, but not explicit, bias significantly predicted greater endorsement of restrictive or controlling clinical interventions. Thus, despite overall positive attitudes toward those with mental illness for the sample as a whole, individual differences in provider stigma were related to clinical care. Mental health professionals, and specifically ACT clinicians, should be educated on types of bias and ways in which biases influence clinical interventions.
The Politics of Cutback Management: A Case Study of Interorganizational Relations and Influence Structures During a Local Government Retrenchment Process

Die Konvergenz von Telekommunikation und Datenverarbeitung hat eine globale Expansion von Netzen und Diensten ausgelost, die von einer Deregulierung des Sektors begleitet wurde. Eine Vielzahl heterogener Akteure auf dem Weltmarkt mus die jeweiligen Entwicklungs- und Produktionsaktivitaten ebenso wie das Angebot neuer Dienste koordinieren. Der alte Modus hierarchischer Koordination, der technische, okonomische und politische Steuerung internalisierte und sich in der Ara souveraner Nationalstaaten fruherer Jahrzehnte etablierte, lies sich nicht in eine transnationale Hierarchie transformieren. Koordination beschrankt sich daher auf die Herstellung technischer Kompatibilitat von Systemen der Telekommunikation. Es hat sich ein Netz internationaler und regionaler Standardisierungsgremien herausgebildet, das standig groser wird. Diese Gremien erarbeiten die benotigten Empfehlungen, die eher optional und komplementar als substitutiv sind, was eine Arbeitsteilung anstelle von Konkurrenz begunstigt hat.
Quercetin Curtails Obesity and Dyslipidemia, but Not Insulin Resistance in Long-Term Type 2 Diabetic Male Wistar Rats Fed the High-Fat, High-Sucrose Diet

It is unclear whether the persistence of Type 2 Diabetes (T2D)-associated insulin resistance in Wistar rats is entirely dependent on obesity and dyslipidemia or other factors are involved. We wanted to reveal whether alleviation of obesity and dyslipidemia by quercetin would sufficiently cure the insulin resistance in diabetic Wistar rats. For this purpose, ninety, male Wistar rats were randomized into three experimental groups (n=30): Normal Control (NC) fed chow diet, Diabetic Control (DC) fed High-Fat, High- Sucrose Diet (HFHSD) and diabetic, Quercetin-Treated (QT) fed the HFHSD and gavaged with quercetin at 50 mg.kg-1 bw.day-1. On Days 0, 60 and 120, Body Mass Index (BMI) and Abdominal Circumference:Thoracic Circumference (AC:TC) ratio were measured on ten rats from each group. Rats were then euthanized and fasting blood samples were withdrawn and used to quantify plasma glucose, Triacyclglycerols (TAG), LDL-cholesterol, total cholesterol, C-Reactive Protein (CRP) and insulin concentrations. Insulin resistance score, Relative Pancreatic Weight (RPW, %) and number of islet of Langerhans were also determined. We show that quercetin normalized BMI, AC:TC ratio, RPW (%) and dyslipidemia, and enhanced the islets number of Langerhans in the QT rats on Day 120 relative to the NC rats. In the diabetic DC rats, AC:TC ratio correlated positively with hyperglycemia and negatively with RPW (%). Quercetin lowered, but failed to normalize hyperinsulinemia, insulin resistance score, hyperglycemia and CRP in the QT rats relative to the NC rats suggesting that other factors are involved in the insulin resistance pathogenesis in T2D Wistar rats. Our data also suggest that AC:TC ratio is a predictor of the obesity-induced T2D in Wistar rats.
Academic Performance and the Great Recession 1 E ¤

In this paper we study how the Great Recession a¤ected university students in terms of performance, with a special focus on the dropout probability. To do so, we use individual-level data on a representative sample of university students in Italy in 2007 and 2011. We measure the severity of the recession in terms of increases in adult and youth unemployment rate and we exploit geographical variation to achieve identi cation. On the one hand, an increase in adult male unemployment rate deteriorates the nancial condition of the family, raising the dropout probability. On the other hand, by reducing the opportunity cost of tertiary education, an increase in youth unemployment rate decreases the dropout probability. Focusing on students who were enrolled at the university before the recession we are able to study the e¤ects of the crisis on performance net from any potential e¤ect on enrollment. We nd evidence that overall, university dropout decreased as a result of the Great Recession and that the probability of on-time graduation increased for more motivated students. The e¤ects, however, are considerably heterogeneous across gender and other socio-economic indicators. JEL classi cations: D12, E32, J24
WATER HYACINTH (Eichhornia Crassipes) AS A REMEDIATION TOOL FOR DYE-EFFLUENT POLLUTION

The potential of water hyacinth (Eichhornia crassipes) to remove pollution load of dye waste were investigated. The experiments were carried with the help of 25%, 50%, 75% and 100 % waste water. There was a significant decrease in the pH, TDS, Conductivity, Hardness, DO, BOD, COD and nitrate nitrogen and ammonium nitrogen. It has been concluded that water hyacinth is an efficient plant for treatment of the effluent discharged from the local dye industries.
Assessing the integrated effects of landscape fragmentation on plants and plant communities: the challenge of multiprocess–multiresponse dynamics

When human activities change the landscape, several processes affecting remnant vegetation take place simultaneously: there is less suitable habitat, populations become isolated and the environmental conditions of the fragments frequently shift. Such changes affect vegetation in different ways – populations become smaller, the genetic exchanges between populations decline and species interactions are altered. The combination of processes taking place during fragmentation and their subsequent consequences generate a large variety of responses, positive and negative, among plants and plant communities. To assess the integrated effects of the processes taking place as a result of fragmentation (isolation, edge effects, fragment size and time since fragmentation) on organisms, we conducted a hierarchical meta‐analysis of the studies reporting the effects of landscape fragmentation on plant species and plant communities. Our review included 259 peer‐reviewed journal articles and 990 data entries. We found the frequency of reports of positive and negative responses to fragmentation were comparable but largely variable. Negative effects of fragmentation due to isolation, edge effects and fragment size were significant; but only edge effects and fragment size had significant positive effects. When looking at specific types of responses to isolation, we found negative effects on density, fecundity, colonization, succession rates and species richness, while positive effects were found on fecundity, herbivory/predation and colonization. Positive responses to edge effects were significant for density, fecundity, survival, growth and richness, and significantly negative for density, survival, colonization and richness. Effects of patch size were mostly significant for both positive and negative responses. We also assessed the effects of landscape fragmentation for different attributes of the studied system and found no differences among biomes, vegetation types, functional groups or life stages. Synthesis. Results of this integrated assessment indicate that broad generalizations about the effects of fragmentation on remnant vegetation may not be possible due the large variety of processes and responses associated with fragmentation. Results also identified key knowledge gaps, and areas of research needed to improve assessment and future management of plant species and plant communities in fragmented landscapes (e.g. lag effects, the role of the matrix and the patch quality and integrated effects along life cycles).

Productivity growth in Latin American manufacturing: what role for international trade intensities?

This paper analyzes the relationship between the intensity of international trade flows and labor productivity for 28 industries in the five main economies in the region (Argentina, Brazil, Chile, Colombia and Mexico)using the Arellano-Bond generalized method of moments (GMM)estimator. The results show that international trade flows contributed through various channels to labor productivity growth in the period 1990 to 2008. These channels, which have been developed in the theoretical literature, are export intensity (share of production exported), import penetration (share of domestic demand covered by imports), the diversification of the export basket and intra-industry trade. The estimation also includes several control variables, of which several turn out significant. In addition to estimates for the total manufacturing sector, we also show results for three different groups of manufacturing industries characterized by different factor endowments: natural resource intensive,labor and capital intensive ones.
The STM Images of Pt ( 111 ) ( 3 × 3 ) R 30 ̊ / CO Surface by DFT Calculations

In this work we have performed total-energy calculations of the chemisorption properties and STM images of Pt (111) ( × 3 3 )R30 ̊/CO surface by using the density functional theory (DFT) and the projector-augmented wave (PAW) method. The calculations show that carbon monoxide molecule (CO) adsorbs on FCC site in the Pt (111) ( × 3 3 )R30 ̊ surface is energetically favored by the GGA-PBE XC-functional, this is in agreement with most of the theoretical calculations which is using different XC-functional at the most. However, these results strongly conflicted with the existing experiments. Actually the calculated workfunction for the FCC adsorption is quite different from the experiments while the atop one is in good agreement with experiments. We speculate that the atop adsorption for ( × 3 3 )R30 ̊/CO is favorable for the adsorption case at the most. Furthermore, we have calculated the scanning tunneling microscopy (STM) images for both adsorption geometries and suggest that there should be existed remarkable differences in the STM images. The present work provides a faithful criterion accounting for the local surface geometry in Pt (111) ( × )R30 ̊/CO surface from surface workfunctions and STM images instead of total-energy calculations. 3 3
The Effect of Earnings Announcement on Share Prices in Ghana: A Study of Ghana Stock Exchange

In an efficient market, information is as plentiful and inexpensive, and the market is expected to immediately absorb any information released to the public. This paper examined the effect of earnings announcement on GSE by analyzing changes in share prices for the period from January 2010 to June 2013. The study population was all the listed companies on GSE and 10 companies were selected for the study. Abnormal returns during an event window of 21 days were determined using the event study methodology by employing the market model on data collected about selected companies. Inferential and descriptive statistics were used to test for significant effect of earnings announcement on share prices. The results obtained indicate that the abnormal returns around the earnings announcement were not significant at a 5 % margin of error and the insignificant cumulative average abnormal returns surrounding the event date are inconsistent with EMH. This suggests that the Ghana stock market does not efficiently adjust to earnings information. It is concluded that earnings announcement depicted no major effect on share prices of companies at the time of the announcement as well as immediately after the announcements.

MECHANICAL PROPERTIES OF WASTE PLASTIC BANNER FIBER REINFORCED CONCRETE

The objective of this research is to determine the mechanical properties of the waste-plastic-banner-fiber reinforced concrete: compressive strength, splitting tensile strength, rupture modulus and modulus of elasticity. Concrete mixtures with different proportions of waste plastic banner fiber were produced and tested: 0%, 0.25%, 0.5%, 1.0%, 2.0% of waste plastic banner fiber. The tests showed that the addition of fiber by 0.5% from the total concrete volume will increase the splitting tensile strength by 14.28% and produce the modulus of elasticity as high as 23,025 MPa (up to 12% from the normal mix) and yield the concrete compressive strength of 35.56 MPa (up to 4.95% of the normal mixture). The rupture modulus will increase by 4.11% as the addition of 0.25% of waste plastic banner fiber.
Analytical Solution for Supersonic Flow on a Conical Body of Rounded Triangle Cross Section via the Perturbation Method

3 Abstract: In the present work flow over a conical body with rounded triangle cross section is studied analytically. In supersonic flow, the boundary layer is very thin and the viscous effects are negligible. The viscous terms in Navier Stokes equations are omitted and the governing equations of the problem are the Euler's Equations. The governing equations are simplified due to the geometry of the body. Spherical coordinate is considered for the problem. The Perturbation expansions are applied for flow variables, the governing equations and boundary conditions are also expanded. Applying the perturbation expansions for flow variables and substituting in the governing equations, two systems of equations are obtained. Solving the zero-order and first-order systems of equations the solution for supersonic flow on a cone of rounded triangle cross section is obtained. Results for flow variables for cone of rounded triangle cross section are presented for different semi-vertex angles of the basic circular cone and various Much numbers.
