FEASIBILITY OF PACKAGING POTATOES IN INSTITUTIONAL SIZE RETORT POUCHES

Packaging potatoes in institutional size retort pouches is analyzed as a possible market outlet for Michigan potatoes. A two-pronged research approach involves estimation of unit costs of retort pouch potato products (RPP) and an assessment of the market potential for RPP in the food service industry. Break-even costs for a six-pound pouch is estimated to be $2.62 (44¢ per pound), which translates to a likely price disadvantage relative to competing products. Food service operators expressed general satisfaction with existing potato products and will not readily switch to use of retort pouch potato products.Agribusiness,

Soviet automated rendezvous and docking system overview

The Soviets have been performing automated rendezvous and docking for many years. This paper will present an overview and brief history of the Soviet AR&D system, based on the open literature and publicly available sources

SUPPLY MANAGEMENT PROGRAM ALTERNATIVES FOR THE TART CHERRY INDUSTRY

Two interrelated supply problems facing the tart cherry industry are long-run cyclical patterns in industry productive capacity and substantial annual supply fluctuations. Following the termination of a federal marketing order in effect for 14 years, the industry has considered a number of other supply management options. None have been adopted on a broad industry basis. Recent proposals involved formation of a multi-state supply management cooperative and use of a state marketing order in Michigan. Annual supply management alternatives include reserve pool, market allocation, and non-harvest. An orchard removal incentive program was proposed to reduce industry productive capacity.Agribusiness,

Soviet automated rendezvous and docking system overview

The Soviets have been performing automated rendezvous and docking for many years. It has been a reliable mode of resupply and reboost. During the course of the Soviet space program, the autodocking system has evolved. The earlier IGLA system was replaced with the current KURS system. Both systems are radar-based. The variation in strength between antennas is used for computing relative positions and attitudes. The active spacecraft has a transponder. From discussions with Soviet engineers, it seems the docking process can be controlled either from the ground or from the active (docking) spacecraft's onboard computer. The unmanned Progress resupply ships regularly dock with the current MIR Space Station. The Soyuz T spacecraft incorporated the IGLA system, and the later Soyuz TM and Progress M Series spacecraft incorporated the KURS. The MIR Complex has both systems installed. The rear port and the KVANT docking port have the IGLA system installed to support earlier Progress ships that use the IGLA. The first Soyuz TM docking occurred in May of 1986, while the first Progress M docked in September of 1989

Evolutionary plasticity of developmental gene regulatory network architecture

Sea stars and sea urchins evolved from a last common ancestor that lived at the end of the Cambrian, approximately half a billion years ago. In a previous comparative study of the gene regulatory networks (GRNs) that embody the genomic program for embryogenesis in these animals, we discovered an almost perfectly conserved five-gene network subcircuit required for endoderm specification. We show here that the GRN structure upstream and downstream of the conserved network kernel has, by contrast, diverged extensively. Mesoderm specification is accomplished quite differently; the Delta–Notch signaling system is used in radically distinct ways; and various regulatory genes have been coopted to different functions. The conservation of the conserved kernel is thus the more remarkable. The results indicate types of network linkage subject to evolutionary change. An emergent theme is that subcircuit design may be preserved even while the identity of genes performing given roles changes because of alteration in their cis-regulatory control systems

2010 Estimated Cost of Producing Hops in the Yakima Valley, Washington State

The enterprise budget provides estimates of production costs for a well-managed hop enterprise in Yakima Valley, Washington as of 2010. Three producer scenarios are presented to demonstrate how the enterprise budget can be used to evaluate situations in which the producer may find him/herself. An interactive Excel Workbook is developed and detailed instructions are provided to allow users to input their own data or make changes to the existing spreadsheets.enterprise budget, hops, Washington

ROBOSIM, a simulator for robotic systems

ROBOSIM, a simulator for robotic systems, was developed by NASA to aid in the rapid prototyping of automation. ROBOSIM has allowed the development of improved robotic systems concepts for both earth-based and proposed on-orbit applications while significantly reducing development costs. In a cooperative effort with an area university, ROBOSIM was further developed for use in the classroom as a safe and cost-effective way of allowing students to study robotic systems. Students have used ROBOSIM to study existing robotic systems and systems which they have designed in the classroom. Since an advanced simulator/trainer of this type is beneficial not only to NASA projects and programs but industry and academia as well, NASA is in the process of developing this technology for wider public use. An update on the simulators's new application areas, the improvements made to the simulator's design, and current efforts to ensure the timely transfer of this technology are presented
