One of the biggest problems, which emerge with the gaining momentum of urbanization, is the loss of identity of cities. New developed areas put pressure on traditional texture and turning them to the irregular areas. In Turkey, this alteration has been come to a common problem of cities that have historical value. It has been seen that new development have the same type of construction and has no respect to city identity. In recent years, the City of Bartın where urbanization has been increased, is in the process of losing its traditional texture. When architecture samples have been started decreasing, unplanned and carelessly done buildings have been started to be dominant on urban texture. In this study, the interaction between new settlement and traditional settlement has been examined; social, cultural and physical typology analyses have been done. The results of analysis compared with contemporary needs, development of plan decisions that reflect identity traditional texture have been aimed to form new settlement models.

Key Words: Urban identity, traditional pattern, Bartın, thypologic analysis, types of modern settlements

The outdoor areas of public institutions that occupy considerably large areas in a city are highly effective on the development and image of a city. Decisions and comments which may have these institutions develop their images; and detect their deficiencies and lead to development projects, are needed. For this, public institutions have become the most effective elements on city development and physical structure. The planning and design of these establishment areas are so important that they be made performed properly. In this aim, questionnaire forms were completed to evaluate the outdoor areas of hospitals, schools university campuses and state lodgings by the subjects who use these establishments.

Key Words: Questionnaire, public institution, use of outdoor area, sufficiency of outdoor area

In the process of Turkish Republic being an EU member, wholesomeness of agricultural products is very important at the pesticide residue concept. The reliability of analytical data produced in the pesticide residue laboratory, and validity of method must be checked with documented evidence. Quality Assurance (QA) and Quality Control (QC) principles are very useful tools for the proving correctness of analytical data. Most of the analytical steps must be controlled in QA/QC system. The purpose of the article reported here was to demonstrate the use of radiotracer technique (14C-pesticide) for some analytical steps such as, the purity/purification of active ingredient, homogenity of sample processing, extraction efficiency (bound residues) cleanup and recovery in QA/QC system.

Key Words: 14C-pesticide, radiotracer technique, quality control/quality assurance

This study was conducted to determine the effects of seed soaking in salicylic acid (10-2 mol/L, 10-4 mol/L, 10-6 mol/L and control) on the growth and some physiological characters in wheat (Triticum aestivum L.) under salinity (8 ds m-1) and non salinity conditions. NaCl reduced the emergence percentage, the growth parameters (shoot and root dry weight), K+/Na+ ratio, osmotic potential and photosynthetic pigments (Chl a, b and carotenoids) contents in wheat seedlings. The emergence percentage was not changed, in contrast, shoot and root dry weight of seedlings, K+/Na+ ratio, photosynthetic pigments (Chl a, b and carotenoids) contents and osmotic potential were increased by salicylic acid treatments under non salinity condition. Seed soaking in SA increased the emergence percentage, osmotic potential, shoot and root dry weight, K+/Na+ ratio, photosynthetic pigments (Chl a, b and carotenoids) contents in the salinity stressed wheat seedlings. These results were indicated that SA has positive effects on plant growth in salinity and non salinity conditions. But the effects of SA was higher on emergenge percentage, K+/Na+ ratio and osmotic potantial in salinity condition compared to non salinity condition was obtained in this study.

Key Words: Salicylic acid, salinity, wheat

Determination of yield potential and combining ability of inbred lines is one of the most important steps in hybrid corn breeding. The objective of this study was to determine the yield potential and the agronomic characters of homozygote dent inbred lines. Thirty lines were topcrossed with the public U.S. inbred line FrMo17 in 2000. F1 hybrids were evaluated in the different yield trials at two locations, Samsun and Tokat, in 2001. Data on combining ability of time to tassel, plant height, ear lenght, number of kernel per ear, 1000-kernel weight and grain yield were investigated. Significant combining ability differences were observed among inbred lines for all traits in both locations. Inbred lines no 15, 16 and 18 had high combining ability in both locations. The highest yielding lines also showed significant positive combining ability effects for plant height, ear lenght and kernel weight. Combining ability was an important selection parameter for these materials.

Key Words : Corn, topcross, combining ability

The term we live in known as conventional is a beginning of the conscious of possibility of risks of depletion. Such reasons like, fossil originated energy sources can be consumed before the time it is guessed, these sources can cause huge and irrevocable catastrophes, they can not be enough to the need of rising energy sources and newly developing technology and for the wish of the developed countries to rise and widen the variety of useable energy, investigators new focused on the searching for new and renewable energy resources. Today, the variety of new and renewable energy sources are increasing, some part gaining value as alternatives of economy, some part of it is still under investigation from its both economic and technical sides and almost everyday, there appears a new source of energy. The most common side of these source are that they do not cause short or long term negative effects. Bio fuels are within the mostly new of these with this aim. The reasons that they can be used in present motor technologies without making any change, as they have a close product to diesel fuel, as it can be gained from both animal and vegetable sources and it has an environment causes investigations to go on this way. It is impossible to use vegetable oils directly to the motors as their high viscosities. So the methods are appliquéd is to solve this problems which.The objective of this research is to determine the feasibility and examine the effect of hazelnut oil methyl and ethyl esters which are produced by transesterification method and blending method used as fuel on the performance and emissions controls of diesel engine. For this purpose, a naturally aspirated, direct injection, single cylinder diesel engine was used. During the test, torque, emissions values and fuel consumption were measured with respect to the engine speed. The brake power, brake specific fuel consumption values are also calculated. Accordingly, hazelnut oil alkyl esters were found to closely similar to those of diesel fuels.

Phytases (myo-inositol hexakisphosphate phosphohydrolase, EC 3.1.3.8) catalyze the release of phosphate from phytate. Several cereal grains, legumes and oilseeds store phoshorus as phytate. Phytases can be produced from plants, animals and microorganisms. Microbial sources, however, are most promising for commercial exploitations and biotechnological applications. The enzyme has been widely used in animal feeding to improve phosphorus nutrition and to reduce phosphorus pollution of animal waste. Phytases have been also used in food industry, preparation of myo-inositol phosphates, paper industry and as a soil amendment. Biotechnology are using for developing new effective phytases with improved properties.

Key Words: Microbial phytase, phytate, feed and food additives, biotechnology
