Opis:: The aim of the present study was to examine the effect of natural substances such as garlic extract, grapefruit extract, vermicompost extract, and chitosan on mycelial growth, sclerotia germination, and biological activity of Rhizoctonia. solani. It was found that the tested substances inhibited mycelial growth and sclerotia germination of R. solani. At the lowest experimental concentration, all biological substances, contrary to the fungicide, had a positive effect on the relationship between R. solani and Trichoderma viride.
Celem pracy było zbadanie oddziaływania substancji takich, jak: wyciąg z czosnku, wyciąg z grapefruita, wermikompost i chitozan na wzrost grzybni, kiełkowanie sklerocjów i aktywność biologiczną grzyba Rhizoctonia solani. Stwierdzono, że badane substancje hamowały wzrost grzybni i kiełkowanie sklerocjów R. solani. W najmniejszym badanym stężeniu wszystkie substancje biologiczne, w przeciwieństwie do fungicydu, działały korzystnie na relacje między R. solani i Trichoderma viride.

Tytuł:: Analysis concerning possibilities of reduction of toxic substances and co2 emission by use of dual fuel diesel engines for seagoing ships main propulsion

Opis:: The goal of the paper is to focus the problem of emission of toxic compounds e.g. NOx, SOx and CO2 from seagoing ships to environment. The VI Amendment to Marpol Convention concerning prevention against air pollution by seagoing ships brought into practice in May 19th 2005 forced ship owners to use means for reduction of environment harmful substances emission to atmosphere. Considerable reduction of these harmful substances can be use dual fuel diesel engines for ship propulsion. Dual fuel engines are fuelled by natural gas having methane as main component. Leading producers of marine diesel engines introduced into production diesel engines DF (Dual Fuel) type. These engines can be fuelled alternatively with natural gas or with heavy fuel oil and marine diesel oil. Today the propulsion by diesel engines fuelled with natural gas is the most popular on ships carrying natural gas cargo i.e. LNG carriers (Liquefied Natural Gas Carriers). Natural gas is freight in liquid form under atmospheric pressure in temperature -163 °C. Due to heat penetration into cargo tanks, the liquefied gas evaporates. Evaporated cargo BOF (Boil Off Gas) is used as a fuel in ship diesel engines. However, dual fuel engines are used on other types of ships not only on LNG carriers. A number of seagoing ships fuelled with natural gas are now under construction. For example container ship 9,000 TEU in Japan shipyard Kawasaki Heavy Industries or container ship 14,000 TEU in Korean shipyard Daewoo Shipbuilding & Marine Engineering for company CMA-CGM. Ships fuelled with natural gas e.g. modern ferries are also built by Stocznia Remontowa Shipbuilding in Poland for Norwegian owner. Adaptation of presently operated ships for fuelling with natural gas is also considered.

Opis:: The use of natural and organic fertilizers is increasing, as it makes it possible to use a significant amount of products from the rendering sector and the environment of livestock farming. This translates into the possibility of maintaining the appropriate biological, physical and chemical properties of the soil, and thus directly affects the state of the natural environment, as well as the safety of production of plant origin food (e.g. cereals, vegetables, fruit) and animal origin food, through feed. The threats from the above-mentioned sources should be properly identified, monitored and, after exceeding the critical values due to the achieved risk level, minimized. Many risk factors in this area are already identified and the relevant requirements are laid down in national and European Community law (e.g. on heavy metals, pathogens). An increasing issue is having comprehensive risk assessments of the potential presence of antimicrobial substances and microbial contamination in animal by-products, organic fertilizers, soil improvers and natural fertilizers. Pilot studies in this field were undertaken at the Department of Hygiene of Animal Feedingstuffs of the National Veterinary Research Institute in Puławy.
