Today, food safety is a common concern in the world. As main source of food, agricultural products’ also worthy attention. By establishing vertical integration model product supply chain, circulation links products can be reduced, and efficiency quality level improved. This paper assumes that under condition simple fresh products, there only one wholesaler retailer chain. Through analysis econo...

In [1] we introduced and studied for product hypergraphs Hn = Qni=1Hi , where Hi = (Vi; Ei) , the minimal size (Hn) of a partition of Vn =Qni=1 Vi into sets that are elements of En = Qni=1 Ei . The main result was that (Hn) = n Y i=1 (Hi); (1) if the Hi's are graphs with all loops included. A key step in the proof concerns the special case of complete graphs. Here we show that (1) also holds wh...

Packing measures Pg(E) and Hewitt-Stromberg measures νg(E) and their relatives are investigated. It is shown, for instance, that for any metric spaces X, Y and any Hausdorff functions f , g ν(X) ·P(Y ) 6 P(X × Y ). The inequality for the corresponding dimensions is established and used for a solution of a problem of Hu and Taylor: If X ⊆ Rn, then inf{dimPX × Y − dimPY : Y ⊆ R} = lim inf Xn↗X di...

Since insuring agricultural products is one of the effective instruments for risk management in agricultural sector, it can reduce risk avoidance among farmers and increase their competence in using production factors and, consequently, increases their inclination towards investment in agricultural sectors. The purpose of the current study was to investigate the factors influencing policyholder...

Quality evaluation of agricultural and food products is important for processing, inventory control, and marketing. Fruit size and skin delamination are two important quality factors for the date industry, especially for high quality dates such as Medjools. Unlike other near-infrared spectrometric approaches, the developed machine vision system uses reflective near-infrared imaging to evaluate ...

Navel orange is one of the characteristic agricultural products in the middle region of china. The traceability system for navel orange can enhance consumer confidence due to the “stained navel orange” incident. Research on the navel orange traceability chain is the foundation and premise of building the traceability system. Based on the analyses of whole food chain of navel orange from origin ...

An abundance of agricultural by-products have been used to feed dairy and beef cattle in Taiwan, in order to reduce the cost of livestock production. Most farmers are not concerned about the nutrient value of agricultural by-products. They need to be educated on how to utilize by-products properly. Research to improve techniques of preservation and the efficiency of utilization of agricultural ...
