To test the effects of fertilizer concentration and growth medium electrical conductivity (EC) on the growth of New Guinea impatiens (Impatiens sp. hybrids or I. platypetala Lindl.), plants of `Selenia' were grown 70 days in a commercial soilless medium and irrigated with solutions of 20N-4.3P-16.6K at concentrations of 0.5, 1.0, 1.5, or 2.0 g·liter-1. In a fifth treatment (“delay”), no fertilizer was applied for the first 14 days after planting, then 0.5 g·liter-1 was applied for the next 14 days, followed by 1.0 g·liter-1 until the end of the experiment. Measurements of shoot dry weight and growth medium EC were made at 14-day intervals. Differences in dry weight between fertilizer treatments became significant (P = 0.0001) 42 days after planting. Over the 70-day experiment, plants grew most with 0.5 g·liter-1 and delay treatments. High fertilizer concentrations (1.5 and 2.0 g·liter-1) caused the most growth suppression and resulted in increasing growth medium EC with time. An EC of ≈1.5 dS·m-1 or higher was associated with suppressed growth beginning 42 days after planting. A mild chlorosis developed on the leaves of some plants at the two highest fertilizer concentrations.

It has been observed that minute amounts of venom from the brown recluse spider, Loxosceles reclusa, are capable of producing cytotoxic changes in cultures of certain mammalian cells (Morgan and Felton, 1965). Since there is little available information concerning the effect of venoms on susceptible cells, we have attempted to characterize, at the electron microscope level, the cytotoxic changes produced by the venom of this spider.Cultures of human epithelial carcinoma cells, strain HeLa, were initiated on sterile, carbon coated coverslips contained in Leighton tubes. Each culture was seeded with approximately 1x105 cells contained in 1.5 ml of a modified Eagle's minimum essential growth medium prepared in Hank's balanced salt solution. Cultures were incubated at 36° C. for three days prior to the addition of venom. The venom was collected from female brown recluse spiders and diluted in sterile saline. Protein determinations on the venom-were made according to the spectrophotometric method of Waddell (1956). Approximately 10 μg venom protein per ml of fresh medium was added to each culture after discarding the old growth medium. Control cultures were treated similarly, except that no venom was added. All cultures were reincubated at 36° C.

Agmenellum quadruplicatum is a unicellular, non-nitrogen-fixing, marine cyanobacterium (blue-green alga). The ultrastructure of this organism, when grown in the laboratory with all necessary nutrients, has been characterized thoroughly. In contrast, little is known of its ultrastructure in the specific nutrient-limiting conditions typical of its natural habitat. Iron is one of the nutrients likely to limit this organism in such natural environments. It is also of great importance metabolically, being required for both photosynthesis and assimilation of nitrate. The purpose of this study was to assess the effects (if any) of iron limitation on the ultrastructure of A. quadruplicatum. It was part of a broader endeavor to elucidate the ultrastructure of cyanobacteria in natural systemsActively growing cells were placed in a growth medium containing 1% of its usual iron. The cultures were then sampled periodically for 10 days and prepared for thin sectioning TEM to assess the effects of iron limitation.

The purpose of the article is to determine the nature, characteristics and keyproblems of the main types of economic and legal instruments for the realizationof foreign direct investment (FDI). the methodological basis of the study is asystematic approach to the processing and compilation of statistics and indicators,as well as methods for their comparison, analysis and synthesis and a method offorecasting decisions on the use of investment potential to increase the attractivenessand volume of FDI attraction. The scientific novelty of the research lies in theanalysis of greenfield and brownfield strategies as the main forms of FDIimplementation, the disclosure of the content and interpretation of data on thereal state of FDI attraction, the search for opportunities to improve the investmentclimate and effective mechanisms for attracting foreign investors. conclusions. Itis confirmed that the investment attractiveness and rating of the country in theinternational market are the main factors for attracting investors. Inaccessibleinfrastructure, inefficient judicial system, high level of corruption and imperfectlegislation are the main obstacles that need to be overcome in order to attractforeign investors’ funds, providing a full package of assistance and support ateach stage of the implementation of investment projects. Greenfield and brownfield(M&A) are the most effective forms of FDI in order to achieve high growth ratesof the domestic economy, improve the level of population well-being andinternationally enter Ukraine. An analysis of the statistics on the effectiveness ofinnovative enterprise development projects, the characteristics of economic andlegal instruments indicate the gradual improvement of the investment climate andthe promotion of FDI inflows into the region’s economy through the implementationof greenfield and brownfield strategies. Examples of effective implementation ofthese strategies in the creation of new enterprises, companies of foreignrepresentation, which are expanding their capacity and entering new domesticmarkets are given. Examples of the brownfield strategy have been analyzed torestart existing and high-quality structural and organizational changes in inefficiententerprises, which have given impetus to improving the economic environment,investment attractiveness of the economy of the region and the country as a whole.
