After mechanical harvesting of 'Concord' grapes was totally implemented, the most time-consuming vineyard operation in Arkansas became pruning. Grape producers complain of decreasing availability of qualified labor for pruning and tieing, and feel that pruning should be the next operation mechanized. Single and double curtain vines were established in a 14-year-old vineyard at the Main Station,...

Consider a mosaic image, the edges of the tesseræ being unrelated to pictorial content. Depending upon grout color, the picture is seen as uninterrupted "behind bars" or divided into tiles by "cracks" as in an ancient oil painting. The phenomenology is explored.

Editorial Hepcidin: inflammation's iron curtain Rheumatologists and their patients are the beneficiaries of a recently identified peptide, hepcidin (Table 1). Isolated from human urine and plasma in the year 2000 [1, 2], hepcidin appears to be the long-sought iron-regulatory hormone responsible for the anaemia of chronic disease [3, 4]. It is more than that: it is an acute-phase reactant, respo...

A new type of intelligent hanger was designed based on single chip and Pro-E software. 3D entity model of actuator and cover curtain mechanism are established by Pro-E. Wings structure of hanger mechanical part was adopted screw rod and motor combination of the lifting mechanism can make the wings outspread and fold, unique cover curtain structure was adopted. Cover curtain rolls up and down th...

In this Letter, we study experimentally a viscous liquid curtain in an annular geometry. Gap and median radius can be varied in such a way that the base of the initially stationary cylindrical curtain is led to oscillate by decreasing the flow rate. Standing and traveling waves in the plane of the annulus are observed and a nontrivial expression linking pulsation to flow rate per surface unit a...

This paper presents a research project named "Automated life-cycle management system for curtain walls in high-rise buildings based on supply chain management," which is jointly performed by the consortium of universities and companies involved in curtain wall design, manufacturing, and construction in Korea. The objective of this research is to improve the efficiency of the current process thr...

Laboratory experiments indicate that an advancing ejecta curtain displaces the atmosphere and creates strong winds that entrain large amounts of fine-grained ejecta. A theoretical model describing the interaction between an atmosphere and the outward moving ejecta curtain allows one to estimate the magnitude and velocity of the winds in the induced ring vortex in order to establish the importan...

— The electrical curtain is an electronic product which is most suitable for the sphere of intelligent home network. It provides the basic feature of intelligent home network such as the followings; various functions, powerful control. It also becomes the ideal technology with inexpensive power-line protocol, energy saving and solar power generation. Generally it is a suitable motor for BLDC to...

This paper describes curtain airbag gas delivery system development work using CFD analysis. The objective of developing gas delivery system was to achieve uniform inflation and reasonable time to position for oblique pole test with 5 %ile female. CFD analysis has been conducted to design gas delivery system of 3 row curtain airbag. The gas delivery system consists of T-diffuser and flexible ga...
