In many European countries, one of the most complex and widely discussed issues addressed by legal systems with respect to forced selling of limited liability and public limited company shares is the impact of possible statutory restrictions on transfers . Thus, while some authors deny the applicability of such provisions (as a possible avenue for commission of creditor fraud) , others support their validity (on the basis of prevention of possible fraudulent actions affecting interests protected by restrictive causes). In my opinion, a solution must be found in which prosecution of creditor fraud co-exists with respect for the rights scheme. As a general rule, this solution would call for applicability of restrictive clauses to cases of forced selling, regardless of whether such statutory provisions are viewed in terms of order or alienation.

Polycyclic Aromatic Hydrocarbons and other toxic compounds from industrial effluents are noted for their high potency for skin, lung, bladder and gastrointestinal cancers. Increased industrialization, and population growth led to greater production of wastes, Pesticides and PAHs have received attention due to their carcinogenic effects. The main objectives of the study were; to collect base line data on the concentration of PAHs in seawater and sediment from the west coast of India, the concentration of PAHs in certain species of fishes, the comparative levels of PAHs in fish, the influence of sediment characteristics on the concentration of PAH in sediment, changes in PAH concentration in water, sediment and fish, to provide a base line concentration of trace metals in water, sediment and fish, the seasonal changes in content of selected trace metals in water, sediment and fish from the west coast of India. The present study revealed that a predominance of silt and clay at all stations in the off Cochin area. The study has provided comprehensive information available to date for PAHs in seawater, sediment and fishes from the west cost of India especially from the Quilon to Mangalore region.

The thesis deals with different aspects connected with the distribution and toxicity of PHC in crude oils in the aquatic environment and marine molluscs. Information has been gathered and presented on the present status of research in the field based on a thorough review of recent literature. It is seen from the literature that the resident time of PHC becomes lesser and lesser when crude oil is discharged in large quantities into the coastal waters where excess oxygenation light penetration, temperature availability and strong tidal currents persist. This results in the reduction of the onslaught of oil pollution. This probably shows that taxic insult of crude oil in tropical shores will be relatively lesser than that occurring in temperate and boreal waters. However, there is no record of major episodal oil pollution comparable in quantum and extent to that of Torrey Canyon or Amoco Cadiz which prevents a more reliable analysis on the issue. Considerable controversy exists on the method of estimation of PHC in seawater. However, Ultra-violet fluorescence spectroscopy has been widely recommended as an analytical tool for the determination of total hydrocarbons. Similarly representation of values as chrysene equivalents has been recognised as the most reliable method of Quantum representation.

The present investigation has addressed the effects of PHC contaminated culture medium on the morphology, physiology and behaviour of shrimps. The shrimp Metapenaeus dobsoni is an important member of the crustacean animal community abounding the oil contaminated benthic regions of Cochin backwater system. Since it is known that true pollutants can disrupt the sustainability of ecosystems by its effect on species, populations and communities,a representative species was used for the study. The results discussed in this work is bound to help in understanding the ecotoxicant resistance that the animal may display under toxic conditions compared to dynamic steady-state systems in nature.

The present work is a base—|ine attempt to investigate and assess the toxicity of water-accommodated fractions (WAF) of Bombay High crude oil. The experimental animal selected for the present study is a euryhaline teleost, Oreochromis mossambicus (Peters), adapted to fresh water. The fish has been selected on account of its economic valve, abundant availability, experimental feasibility, ease of rearing and maintenance and also because it is one of the commonly cultured species in the South-East Asian countries.

There exists a need for potential microorganism that could facilitate effective bioremediation of crude oil pollutants in the environment. Hence it was desired to isolate a potential bacterium from marine sediment, which often experiences oil pollution and develop a bioprocess for crude oil biodegradation. In the present study the sediment deposits in the beach of Munakkal, Trichur dist, Kerala, collected immediately after the major event Tsunami in 2004 was collected and analyzed by enrichment culture technique towards isolation of potential strains that could degrade crude oil and its fractions. From the results obtained it was found that the sediment deposits harbor several bacteria with potential for degrading hydrocarbons. However, among the strains obtained, isolate no. BTTS 10 showed capabilities for utilizing both alkanes and aromatic hydrocarbons and hence the same was selected for further studies.

In the present study an endeavour has been made to analyse the acute toxicity of WAFs of Bombay High crude and Light Diesel oil on commercially important bivalve species Perna viridis and Perna indica by static bioassay methods. The toxic effects of chemicals in the WAF on the organisms ; their tissues and eventually on rate functions have been elucidated. Marine oil pollution not only affects productivity and quality of marine organisms but also eventually affects the health of human population due to a possible health risk by way of consumption of oil contaminated seafood

Objetivo: Identificar la prevalencia de los factores de riesgo psicosocial intralaboral y extralaboral y su relación con la salud percibida en un grupo de conductores de vehículos del sector de hidrocarburos que trabajan en una empresa de transporte terrestre de Bogotá. Participaron 125 conductores de sexo masculino, que contestaron a una ficha de datos sociodemográfico, los cuestionarios de factores de riesgo psicosociales intralaboral Forma B y extralaboral y cuatro subescalas que conforman el componente de salud mental del cuestionario de calidad de vida SF36 en su versión validada en Colombia. Los resultados demostraron que las variables que conforman el Componente de Salud Mental presentan correlaciones altas y positivas y correlaciones negativas y moderadas con las variables que evalúan los factores de riesgo psicosociales intrala y extralaborales. Se concluye que las correlaciones negativas entre salud mental y factores de riesgo psicosocial intra y extralaborales demuestran la necesidad de realizar acciones de prevención para evitar la ocurrencia de trastornos mentales causados por inadecuadas condiciones psicosociales.

The aim of this research was to identify the criticalcompetence of success of the commercial adviserin a company providing insurance and health services.For this research a sample of 34 commercialadvisers. The sample was divided into four groups(two per product and two per criterion of success).Systematic fi eld observations, interviews of criticalincidents, application of response tests and salesworkshops were used to evaluate the differentialcompetences that the successful advisers wereshowing in relation to the advisers de fi ned as average.The success criteria were based on the generatedcommission performance over the 10 months. Allin all, signi fi cant differences were found betweenthe “successful” and “average” groups. Furthermore,competences that correlate positively with atop sales performance were observed and competencesthat have major level of discrimination betweenthe “successful” and “average” groups wereestablished. Orientation to achievement, planningand management, information search, commercialaggressiveness and strategic vision are the competencesthat were considered to be key in the topperformance of a sales agent or commercial adviser.Additionally, the results in the response testswere analyzed in the four study groups, withoutobserving signi fi cant differences between them,which supports the theoretical framework of thepresent study.
