Benefit-cost analysis of apiculture farm.
The market of bee products is being expanding in the last years. To make the apicultural farms successful, it requires raw materials, manpower, market but also quality of bee products (K. H. Devkota, 2006). In this context, the aim of the present study is to evaluate the profitability of apicultural farms by implementing the modern management instruments: new technologies, good apicultural practices, and HACCP guide. Benefit-cost analysis was applied to evaluate the apicultural farms of Transylvania. The analyse was made in two situations: 1 st -implementation of the classic methods and 2 nd – implementation of the modern management system (diversification of the products and increase of the quantity). The costs of production were divided in two categories: direct costs and fixed costs.
Benefit-Cost Analysis of Apiculture Enterprise: A Case Study of Jutpani VDC, Chitwan, Nepal
A survey study was conducted to study the benefit-cost analysis of apiculture enterprise in Jutpani VDC, Chitwan district. Data were collected by interviewing randomly selected 18 beekeepers for sample survey. Benefit : Cost (BC) ratio of apiculture was computed by including and excluding the revenue obtained from colony selling. Only 61.11% of beekeepers sold bee colonies for earning income. The study revealed that BC ratios of apiculture were 2.41 and 1.58 in the case of inclusion and exclusion of the income received from the colony selling, respectively. It showed that apiculture industry was running in profit in both cases. In the former case, the BC ratio ranged from 0.97 to 6.22 and about 88.88% beekeepers were in profit. The BC ratio in the later case ranged from 0.43 to 3.41 and about 77.77% beekeepers were in profit. The number of colonies ranged from 2 to 54 with an average of 21.33 colonies per bee farm. In the former case, average annual income was Rs. 70758.33 (US$ 969.29 approximately) per farm and Rs. 49588.31 (US$ 679.29 approximately) in the later case. Likewise, the average income per colony per annum was Rs. 3317.31 (US$ 45.44) and Rs. 1777.65 (US$ 24.35 approximately) in the former and later case, respectively. Key words : Apiculture, benefit-cost ratio, beekeeper

Mathematical Modeling of Scour and Deposition
Electronic computers are opening up the field of sedimentation engineering by permitting the analysis of problems which heretofore have required too much time and effort. Movable stream bed profiles are being calculated in addition to water surface profiles. The initial gradation of sediment material in the stream bed may be prescribed to facilitate the calculation of an armor layer. This gradation is continually changed by the computer program in response to sediment particles being deposited on the stream bed and material on the stream bed being removed to satisfy transport capacity. Hydraulic sorting of sediment by grain size is accomodated. The stream bed does not have to be represented by a single grain size. Retardance of motion because of armor layer is calculated.
