Abstract. The paper outlines the main problems related to the technical service of machines and equipment used in dairy farming. The authors analyze the companies that provide their services to dairy farms of various sizes and forms of ownership, ranging from personal subsidiary farms to agricultural holdings. The main disadvantages of technical service of small and medium farms are shown, namely: large number and disunity of individual equipment suppliers; lack of incoming control of products and materials being in contact with milk; inconsistency in a number of cases of the proposed technical and technological solutions and equipment operation modes with the international requirements and other regulatory documents; impossibility of providing qualifi ed consulting, technical, fi nancial, legal and economic support to agricultural producers. The authors propose a structural and logistic model of a regional multifunctional service center for the livestock breeding industry, providing comprehensive technological, technical and operational services related to consulting, training, choosing the best available technologies and appropriate sets of machines. The multifunctional service center is expected to unite the disparate eff orts of regional service companies and dealers, improve the quality of services provided to commodity producers, and raise the level of production on small and medium-size farms.

Aerosol samples were collected in Phoenix, Arizona on eleven dates between July 1989 and April 1990. Elemental compositions were determined for approximately 1000 particles per sample using an electron microprobe with an energy-dispersive x-ray spectrometer. Fine-fraction samples (particle cut size of 1 to 2 μm) were analyzed for each date; coarse-fraction samples were also analyzed for four of the dates.The data were reduced using multivariate statistical methods. Cluster analysis was first used to define 35 particle types. 81% of all fine-fraction particles and 84% of the coarse-fraction particles were assigned to these types, which include mineral, metal-rich, sulfur-rich, and salt categories. "Zero-count" particles, consisting entirely of elements lighter than Na, constitute an additional category and dominate the fine fraction, reflecting the importance of anthropogenic air pollutants such as those emitted by motor vehicles. Si- and Ca-rich mineral particles dominate the coarse fraction and are also numerous in the fine fraction.
