Mulch drip irrigation (MDI) technology can effectively solve the problem of insufficient temperature accumulation during pre-fertility period and facilitate efficient supplementation water fertilizer fertility in spring corn planting. Moreover, this local MDI also has impacts on farmland environment. To investigate effect salt environment farmland, a field study cultivation was carried out at W...

A growing number of applications require high capacity, high throughput tertiary storage systems [1] [2]. We are investigating how data striping ideas apply to arrays of magnetic tape drives. Data striping increases throughput and reduces response time for large accesses to a storage system. Striped magnetic tape systems are particularly appealing because many inexpensive magnetic tape drives h...

Measured replay pukes, recorded on Metal Evaporated tape, show a strong asymmetry and dependence on the direction of tape movement. It is found that pulse height and pulse width are unequal for both directions of tape movement. This is attributed to the non longitudinal easy-axis direction which causes differences in headtape geometry for both directions resulting in a different transition widt...

An accurate noncontact method of characterizing Ag-BiSCCO tape is reported, using the trapped field, , of a field-cooled tape. The dimensions of the tape make it possible to calculate in closed form a very simple expression, relating trapped field to transport current. Short lengths of tape, 4 (cm), are used to experimentally confirm the model. The model applies to any length of tape for which ...

The purpose of this study was to measure daily and seasonal evapotranspiration and daily crop coefficient of two common varieties of sunflower (Sirna and Euroflor) via drip-tape irrigation system. For this purpose, the sunflower water use was determined by daily monitoring of soil moisture at the depths of 10, 20, 30, 40 and 60 cm, and the crop evapotranspiration (ETC) was measured using volume...

The friction coefficient is an important parameter in designing magnetic tape transports. We have introduced laser surface texturing to reduce the friction coefficient between guides and magnetic tape. The surface features enhance the formation of an air bearing and hence, reduce the friction coefficient. INTRODUCTION Lateral tape motion (LTM) is defined as the time-dependent motion of the tape...

INTRODUCTION The objective is to evaluate the accuracy of medication dosing and the time to medication administration in the prehospital setting using a novel length-based pediatric emergency resuscitation tape. METHODS This study was a two-period, two-treatment crossover trial using simulated pediatric patients in the prehospital setting. Each participant was presented with two emergent scen...

The purpose of this study was to determine the environmental stability and life expectancies of magnetic media used with certain high density, digital recording tape systems, specifically the IBM 3590 and both Quantum’s Digital Linear Tape (DLT) and Super DLT products. The goal of the study was to compare the tape stabilities and life expectancies of the corresponding tape media and tape storag...

In the mid-1980s, tape storage appeared to be heading toward the graveyard. Storing information on large reels of tape that had to be manually mounted was expensive, inefficient, and prone to human error. In addition, competition from hard disk drives (HDDs) was growing. Data access on HDD was faster because the data was stored in a manner for rapid random access, not linearly as on tape, and H...
