Changes in Chemical and Physical Properties of Pine Tree Substrate and Pine Bark During Long-term Nursery Crop Production
The objective of this study was to evaluate a pine tree substrate (PTS) for decomposition, changes in physical and chemical properties, and substrate carbon dioxide (CO2) efflux (microbial activity) during a long-term production cycle under outdoor nursery conditions. Substrates used in this study were PTS constructed using a 4.76-mm hammer mill screen and aged pine bark (PB). Plastic nursery c...
متن کاملFabrication of suction-cup electrodes for electromyography.
Many kinds of surface electrodes are used today in EMG, the small silver and gold cup being the standard electrode in the United States. A suction-cup surface electrode is rarely used but several years of experience with many kinds of electrodes in our laboratory have led us to the conclusion that this electrode has many practical qualities. The suction-cup electrode has several advantages over...
متن کاملLaboratory Bioassay and Greenhouse Evaluation of a Pine Tree Sub- strate Used as a Container Substrate
Bioassays with tomato and lettuce seeds and three plant experiments with marigold (Tagetes erecta L.) ‘Inca Gold’ were conducted in the laboratory and greenhouse, respectively, in order to investigate possibilities of determining and mitigating the effects of phytotoxins in pine tree substrate (PTS). PTS is produced by grinding loblolly pine tree (Pinus taeda L.) logs, and using as horticultura...
متن کاملModeling of Substrate Noise Impact on a Single-Ended Cascode LNA in a Lightly Doped Substrate (RESEARCH NOTE)
Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...
متن کاملDate Wastes as Substrate for the Production of a-Amylase and Invertase
Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...
