ABSTRACT
Samples from the designated points in the east of Uluabat Lake were taken and Total Coliform and Escherichia coli were enumerated in these samples by employing Pour-Plate Method. Level of pollution in Uluabat Lake was determined according to the Qualty Classification of Water in Water Pollution Control Regulations. Results indicated that quality of the water at some regions of the lake may be classified as II. ör III. Class whereas, at some regions where fecal contamination is high, it appeared to be IV. Class.

ABSTRACT
In this study, the spiders of a sainfoin (Onobrychis sativa Lam.) field located in Yüzüncü Yıl University Campus were studied. The field is about 4.500 square meler. On 27.4.1995 twelve pitfall traps were set with 5 m intervals into the field, and served weekly until 27.7.1995. The collection was made also with hand aspiratör in order to determine the vegetation fauna. During the study period a total of 502 specimens were captured by pitfall traps while 284 specimens collected by aspirator. 63 species were determîned as belong to 16 families from 567 mature specimens. The most encountered family was Gnaphosidae, followed by Lycosidae and Thomisidae. The most captured species was Xysncus robusta (Hahn). Gnaphosa opaca Hermann, Gnaphosa microps Holn, Zelotes aurantiacus Miller and Cicurina cicur (Fabricius) were recorded first time from Turkey.

ABSTRACT
Wastes which are generated in varying sanitary authorities are called clinical wastes or hospital wastes. Clinical wastes should be handled, transported and disposed off properly for the health of peopie and environment. In this study present clinical waste managemeni in Bursa was studied by conducting polis in 12 pilot areas. Results of the polis indicated that clinical wastes are separated as domestic and infectious, but hazardous chemical wastes are not separated properly. Infectious wastes are disposed off by mixing with domestic solid wastes at present. However a project for the incineration of clinical wastes is being carried out by Bursa Municipality.

ABSTRACT
In this study, the effects of the crude extracts, obtained from Urtica dioica, Hypericum androsaemum, Nerium oleander, Prunus laurocerasus, Aconitum nasutum, Laurus nobilis, Rhododendron caucasicum, Olea europaea, Punica granalum and Daphne glomera on the replİcation of Autographa californica nuciear polyhedrosis virüs (AcNPV) were investigated by determining the concantration of progeny virüs. As a result of this study, we detennined an inhibitory effect on the virüs concentration by utilizing the extract of U, dioica, H. androsaemum, L, nobilis, A. nasutum and R. caucasicum. On the other hand, we found that the crude extracts of N. oleander, P. laurocerasus, P. granatum, O, europaea and D. glomera estracts enhanced the virus concentration significantly.

ABSTRACT
The cases of drops and jets have been searched experimentally for various conditions in trickling filters and a relationship has been found with calculation between the unit flowrates and the specific surface areas. it is found that wastewater effects this relationship. in addition to this another relationship has been found between spherical materials and comered ones with the same specific surface. As a scientifical and economical conclusion, this study otiers some significant advantages such as optimum flow characteristic, optimum specific surface, optimum dimension of support material and increasing removal efficiency for trickling filler.

ABSTRACT
Adana, is the most important city in Çukurova Region from the point of agricultural products, and it has important contributions to the economy of the country with the products of cotton, corn, vegetables and citrus. The control by chemicals which emphasizes the use of pesticides is widely used because of the climatic and ecological characteristics of the region which is suitable for the improvement of diseases and weeds. In this research, the amounts of pesticides used on some important products have been investigated.
