EFFECT OF WATER ACIDIFICATION ON PERFORMANCE, CARCASS CHARACTERISTIC AND SOME VARIABLES OF INTERMEDIARY METABOLISM IN CHICKS

The effect of water acidification on performance and some biochemical parameters was studied in 100 one day old broiler chicks (Ross 308) divided into control and treatment groups (n = 50) supplied with drinking water supplemented with acidifier (blend of acids) in a concentration of 0.2 % during the whole experimental period. Final body weight, hot carcass yield, abdominal fat pad and metabolic variables in the blood serum except for aspartate aminotranspherase (AST) level which was significantly lower on 35th day (p<0.01), were not affected by the acidifier. Higher weight gain in the treated group due to better feed efficiency was observed in the first phase. Higher feed intake in the third phase of the trial caused higher final feed conversion ratio (p<0.01). Use of the acidifier positively affected bird health status (zero mortality) which was reflected in higher EEI values observed in the treated group on the 35th, as well as 42nd day of the trial.
Influence of host plants on specialist / generalist aphids and on the development of Adalia bipunctata (Coleoptera: Coccinellidae)

The aim of this work was to determine the impact of allelochemicals (glucosinolates/isothiocyanates) from Brassicaceae (Brassica napus and Sinapis alba) at two trophic levels in relation to biological control efficacy. The impact of these plants on aphid Myzus persicae (Sulzer) and Brevicoryne brassicae (L.) and ladybird Adalia bipunctata (L.) biology can be assessed by observation of several developmental parameters: mortality, development duration and adult weight. Sub-lethal toxicity can also be measured through the reproductive parameters of fecundity and/or egg viability. While both specialist and generalist aphids were positively influenced by Brassicaceae species, mixed effects are recorded in ladybird performances following the aphid species/host plant combinations. Significant differences appeared according to aphid host plant and aphid species. This work enhanced the influence of Brassicaceae plants either as cultivated species (B. napus) or as set-aside (S. alba) on both pests and beneficial insects. The allelochemical presence in plants must be taken into account in programs of integrated pest management due to their direct influence on biological control agents.
PALEOCENE-MIDDLE MIOCENE FLEXURAL-MARGIN MIGRATION OF THE NONMARINE LLANOS FORELAND BASIN OF COLOMBIA

A foreland basin is a dynamic system whose depositional systems migrate in response to changes in tectonic uplift patterns, sedimentary filling processes and isostatic rebound of the lithosphere. The Paleocene-middle Miocene foreland system of the Llanos foothills and Llanos basin of Colombia includes regional unconformities, abrupt changes in lithology/stacking patterns and flooding surfaces bounding reservoir and seal units. Here we integrate a systematic biostratigraphic study, stratal architecture and tectonic subsidence analyses, regional seismic profiles, and provenance data to define the diachronism of such surfaces and to document the direction of migration of foreland depozones. In a flexurally-deformed basin, sandstone composition, rates of accommodation and sediment supply vary across and along the basin. We show how a coeval depositional profile in the Llanos foothills-Llanos foreland basin consists of litharenites interbedded with mudstones (seal rock, supplied from the orogenic front to the west) that correlate cratonward with organic-rich mudstones and coal (source rock), and to amalgamated fluvial-estuarine quartzarenites (reservoir rock, supplied from the craton to the east) adjacent to a subaerial forebulge (unconformity). This system migrated northward and eastward during the Paleocene, westward during the early-middle Eocene, and eastward during the Oligocene. In the lower-middle Miocene succession of the Llanos basin, identification of flooding events indicates a westward encroaching of a shallow-water lacustrine system that covered an eastward-directed fluvial-deltaic system. A similar process has been documented in other basins in Venezuela and Bolivia, indicating the regional extent of such flooding event may be related to the onset of Andean-scale mountain-building processes.

Some bounds on convex mappings in several complex variables

The coefficient bounds and the Growth and Distortion Theorems for convex functions in one complex variable are generalized to several variables. The holomorphic mappings studied are defined in the unit ball or some other domain of one of the first three classical types. Each mapping takes its domain onto a convex set in a one-to-one fashion. The coordinate functions of each mapping have multivariable power series about the origin. The best possible upper bounds are found for certain combinations of the coefficients of these power series. In case the domain is the unit disk in the plane, these bounds reduce to the classical coefficient estimates for convex functions. As an application, these coefficient bounds are used to obtain the best possible upper and lower bounds on the growth of the magnitude of each mapping in terms of the magnitude of the independent variable. Also, estimates on the magnitudes of various derivatives of each mapping are found.
A New Computational Method for Optimizing Nonlinear Impulsive Systems

In this paper, we consider a system that evolves by switching between several subsystems of ordinary differential equations. The switching mechanism in this system induces an instantaneous change in the system’s state, which can be controlled through a set of decision parameters. We develop a new computational method, based on nonlinear programming, for optimizing the system parameters and the subsystem switching times. We then successfully apply this method to two interesting examples.

The revolution of globalization, computerization and information technology has entered to Jordanian market. This phenomenon requires company's attention of human element and the acquired knowledge, experience and the development of the so-called concept of intellectual capital. (IC) In this study I used only the human capital as a part of IC. This study aims to exploring the relationship between human capital investment (HCI), and corporate financial performance. This study used an 11 industrial sectors listed of Amman Stock Exchange from 2005to 2011. Correlation analysis tests used in this study and the results indicate the high positive significant relationship between HCI and corporate financial performance related to, ROE , PTBV , log of sales , log of assets , DPS and ICR but no significant relationship between HCI and WCTO. The researcher recommends industrial companies to strengthen and stimulate the concept of human capital in the companies and the need for develop administrative innovation program. For future analysis may be used more sectors listed in market in addition used the all parts of intellectual capital related to structural and physical capital with corporate financial performance.
A microencapsulated blend of organic acids and natural identical flavours reduces necrotic enteritis-associated damages in broiler chickens.

Six-hundred ROSS 308 broilers were allocated in 24 pens divided into 3 experimental groups (d0): the control diet (CTR), the control diet added with Galliacid®S at 300 ppm (GAL S), a microencapsulated blend of organic acids and natural identical flavours (EU patent 1391155B1; Vetagro srl, Italy), and the control diet added with a different blend of organic acids (WSB) added at 300 ppm. Birds were fed a wheat-based diet without coccidiostat and at d9 were inoculated with live vaccinal Eimeria oocysts; at d15 animals were infected with Clostridium perfringens. Mortality was registered and dead animals were analysed for necrotic enteritis (NE) lesions; growth performance of animals was calculated and analysed with 1-way ANOVA, whereas mortality analysis was run with chi-square test. At d21, following challenge, mortality was significantly reduced in the GAL S group (GAL S:21.8%; CTR: 37.4%; WSB: 43.6%; P<0.001). Feed conversion during the challenge period (15-21d) was significantly lower for GAL S than the other groups (GAL S: 2.4; CTR: 3.2; WSB: 4.7. P<0.05). Galliacid®S allowed to improve growth performance in a NE challenge model when compared to a negative control diet and to wider spectrum blend of organic acids.
Application of Synthetic Storm Technique for Diurnal and Seasonal Variation of Slant Path Ka-Band Rain Attenuation Time Series over a Subtropical Location in South Africa

As technology advances and more demands are on satellite services, rain-induced attenuation still creates one of the most damaging effects of the atmosphere on the quality of radio communication signals, especially those operating above 10 GHz. System designers therefore require statistical information on rain-induced attenuation over the coverage area in order to determine the appropriate transmitter and receiver characteristics to be adopted. This paper presents results on the time-varying rain characterization and diurnal variation of slant path rain attenuation in the Ka-band frequency simulated with synthetic storm techniques over a subtropical location in South Africa using 10-year rain rate time-series data. The analysis is based on the CDF of one-minute rain rate; time-series seasonal variation of rain rate observed over four time intervals: 00:00–06:00, 06:00–12:00, 12:00–18:00, and 18:00–24:00; diurnal fades margin; and diurnal variation of rain attenuation. Comparison was also made between the synthesized values and measured attenuation data. The predicted statistics are in good agreement with those obtained from the propagation beacon measurement in the area. The overall results will be needed for an acceptable planning that can effectively reduce the fade margin to a very low value for an optimum data communication over this area.
Optimal Bequest Taxation and Capital Subsidies Over the Life-Cycle

We study optimal bequest and capital taxation over the life-cycle in an OLG model. In this environment, we show that the efficient allocation can be implemented via age-dependent linear taxes/subsidies on capital income and bequests. First, as long as the degree of self-control problem is weakly decreasing with age, optimal bequest taxes are always strictly positive, independent of the assumptions about the degrees of sophistication over the life cycle. Second, we find that capital (savings) should typically be subsidized. In particular, we show that when the degree of self-control problem is weakly increasing, capital subsidies should increase with age, independent of the assumptions about sophistication over the life cycle.
Sex ratio, length-weight and length-length relationships of Amblypharyngodon mola (Cyprinidae) in the Payra River, southern Bangladesh

Sex ratio, length-weight and length-length relationships of Amblypharyngodon mola were studied in the Payra River during February 2016-January 2017. Monthly samples were collected from the small-scale fishers of set bagnet fishery in the Payra River. All specimens were sexed out and standard length (SL), total length (TL), fork length (FL) and body weight (BW) were measured. The overall sex ratio showed no significant difference between sexes. However, the monthly sex ratio was 1:1 for almost all the year, except in June when females were significantly more abundant than males. With regard to the size class, the sex ratio was found to be non-significant up to 4.0 cm TL, however; at 5.0 cm TL the number of male was significantly higher than female and after that the number of female increased significantly than male till the maximum size class. The allometric coefficient ‘b’ of the LWRs between SL vs. BW and FL vs. BW indicated negative allometric growth and isometric growth respectively for both sexes. While TL vs. BW indicated positive allometric growth in males and isometric growth in females. On the other hand, the LWRs for pooled data indicated negative allometric growth, positive allometric growth and isometric growth for SL vs. BW, TL vs. BW and FL vs. BW respectively. The allometric coefficient ‘b’ of the LLRs between SL vs. TL, SL vs. FL and TL vs. FL indicated positive allometric growth, isometric growth and negative allometric growth respectively for both sexes. However, the pooled data shows positive allometric growth between SL vs. TL, negative allometric growth between SL vs. FL and between TL vs. FL. It was concluded that the data generated from the study will form a baseline tool for effective fisheries management and sustainable exploitation of A. mola in the Payra River as well as surrounding waters of Bangladesh.
The Internationalization of Industrial Relations in Europe: Prospects and Problems

European industrial relations are rapidly internationalizing; internationalization, however, is not necessarily de-nationalization. Even as European integration accelerates, national politics and industrial relations will remain the principal arenas for the social regulation of work and employment in Europe. The paper investigates the implications of European industrial relations developing into a multi-level system within which national regimes compete with each other in an integrated international market. In particular, it tries to outline the emerging new peace formula between business and labor in Europe, which is centered on the notion of joint competitiveness, and its consequences for social protection and the regulation of labor markets. Five examples are given for the continuing importance of national industrial relations in integrated Europe: the renewal of tripartite concertation at national level, especially under the pressure of the Maastricht criteria; the likely impact of European Monetary Union on national collective bargaining regimes; the practical consequences of the European Works Councils Directive of 1994; the experience with the Social Dialogue since the Maastricht Treaty; and the Posted Workers Directive, which is discussed as a possible paradigm of the future relationship between European and national social protection in Europe.
Population Status and Habitat Selection of the Endangered Key Largo Woodrat

Abstract Over the last two decades, declines in trap success, stick-nest density and population density estimates have fueled concerns that the federally endangered Key Largo woodrat (KLWR, Neotoma floridana smalli) population is declining. Information on the current population status and habitat selection of KLWR is needed in the recovery of this population. We trapped on 60 (1-ha) randomly-placed grids (20 grids in each of three hardwood hammock age-classes). Grids were trapped from March–September 2002 and April–August 2004. Population estimates for the two trapping periods were 106 (95% ci 30–182) and 40 (95% ci 5–104) individuals, respectively. Greater than 80% of all KLWRs captures occurred in the young hammock age-classes (disturbed after 1971). Young hammocks were characterized by a more open canopy, smaller overstory trees, fewer logs, greater dispersion of overstory trees and a different species composition than old and medium age hammocks (P < 0.024). Contrary to previous research, KLWRs were found to nest in rock piles and garbage piles more than other materials. Results from this study suggest the KLWR population is critically low and management efforts should focus on the creation and restoration of young hammock habitats.
Lifetime Cancer Risk and Hazard Quotient of BTXs Compounds in Iranian Petrochemical and Petroleum Depot Workers

Exposing to the high-level of BTXs concentration can occur in the oil-dependent industries and may cause considerable adverse impacts on the health of employees. The main objective of the present study firstly is determining the exposure of petrochemical and oil depot workers to benzene, toluene, ortho and methyl xylenes, and p-xylene (BTXs), and secondly is estimating the lifetime cancer risk (LCR) and non-carcinogenic risk using the hazard quotient (HQ). This cross-sectional study is conducted on 85 workers at petrochemical (34 subjects) and oil depot (51 subjects) industries of Iran in 2016. In order to determine the exposure concentrations of BTXs, through inhaling way, individual sampling was carried out according to the NIOSH 1501 method. Then, estimating LCR of benzene, and non-carcinogenic risk of benzene, toluene, ortho and methyl xylenes, and p-xylene, using the HQ, has been conducted regards to criteria recommended by USEPA. The mean exposure concentration of benzene among the oil depot workers was higher than the petrochemical workers, but this difference was not statistically significant (P = 0.162). The mean exposure concentration of benzene in the oil depot workers (2.1 ± 2.53 mg/m3) was higher than the occupational exposure limits provided by the American conference of governmental industrial hygienists (ACGIH_TLV = 1.67 mg/m3). The mean concentration of toluene in the exposed workers of the oil depot (46.81 ± 22.43 mg/m3) was higher than the exposed workers of petrochemical (41.83 ± 30.06 mg/m3), but this difference was not statistically significant (P = 0.412). The results of carcinogenic and non-carcinogenic risk assessment revealed high-risk exposure level in the both investigated groups. The mean LCR of benzene in the oil depot workers was higher than the petrochemical workers (1.681E-3 and 1.163E-3, for the oil depot and petrochemical, respectively). The LCR of benzene and HQ of BTXs in the both investigated groups were higher than the reference values. In order to reduce occupational exposure to BTXs in the investigated oil depot and petrochemical, control measures should be taken in the future, as soon as possible.
Management of Ventilator-associated Pneumonia in Paediatric Setting

Ventilator-associated pneumonia (VAP) is the second commonest nosocomial infection in paediatric intensive care units. New definitions about VAP have been proposed recently for better epidemiological study and clinical trials. Management approach is mainly based on adult recommendation because of scanty paediatric studies. Multidrug resistant microorganisms can cause both the early and the late onset VAP. Possible risk factors for VAP include longer duration of ventilation, immunodeficiency, use of immunosuppressive drugs, neuromuscular blockade, genetic syndrome(s), reintubation and transport of critical patients. To have a more reliable diagnosis, quantitative or semi-quantitative bacterial cultures using bronchoscopic or nonbronchoscopic methods should be performed before initiation of the de-escalation therapy, which is the current trend of management. The threshold bacterial count of bronchoalveolar lavage in diagnosing pneumonia is still controversial in Paediatrics. Initial empirical treatment with combination antibiotics therapy providing a broad spectrum cover to decrease the mortality should be considered, which could later be narrowed to single sensitive antibiotic based on bacterial culture. Shorter duration of antibiotic(s) of 8 days is equally effective as the 15-day treatment except in Pseudomonas aeruginosa pneumonia. Good nursing care with utmost infection control practice is the paramount element in the prevention of VAP.

Occult Hepatitis B infection (OBI) in vaccinated groups, a metanalysis

Nowadays, the presence of HBV DNA in the absence of HBsAg; occult hepatitis B infection; (OBI), is a known clinical entity along with the rapid influx of research being conducted on its clinical relevance. Biologists and clinicians alike have a recent-standing interest in this regards. OBI has been described in several clinical settings. However, the data on its prevalence among immunized and non-immunized healthy general population, in particular, among health care workers (HCWs) is ambigous. This review attemps to explore the significance of OBI in vaccinated groups as a special subject. The prevalence of OBI among general population, vaccinated children/general population and health care workers were: 157 (5.2%), 222 (6.7%) and 33 (1.8%), respectively. The prevalence of anti-HBc among OBI-positive subjects were: 64 (40.7%), 133 (82.7%) and 27 (81.8%), respectively. OBI is partly prevalent in general population and in vaccinated individuals, especially in those who born to HBsAg positive mothers. HBV serological surveys are not enough adequate and sensitive to rule out the presence of HBV DNA. For high-risk groups (subjects born to HBsAg mothers, health care workers, isolated anti-HBc, etc) sensitive molecular tests based on real time PCR should be applied for a proper diagnosis.
ON SEMANTIC CONCEPT SIMILARITY METHODS

Semantic matching is important in research areas including databases, e-Business, case-based reasoning (CBR), information retrieval, information integration, web services and natural language processing. In particular, semantic concept matching using taxonomies is an important technique in these areas. We present a survey of semantic concept similarity algorithms that can be used for concept matching in taxonomies. We also propose a new approach that provides a finer concept granularity measure.
