Effects Of Temperature And Ripening Stage On The Respiration Rate Of Tomatoes, Ali̇ Batu
Effects Of Temperature And Ripening Stage On The Respiration Rate Of Tomatoes, Ali̇ Batu
Turkish Journal of Agriculture and Forestry
The effects of storage temperature and ripening stage on the ripening rate of freshly harvested tomatoes before storage were determined. Respiration was slower in tomatoes harvested at mature green stage of ripening, and the respiration rate increased until the tomatoes reached to the pink and light-red stages of maturity. The maximum CO 2 production occurred in toma-toes harvested at pink, light-red and red stages of maturity, whereas the minimum O 2 consumption occurred in tomatoes harvested at turning, pink and light-red stages of maturity. The highest levels of ethylene were produced by tomatoes harvested at breaking, turning and pink stages …

Comparison Of The Centroid Method And Four Standard Formulas For Estimating Log Volumes, Hakki Yavuz
Turkish Journal of Agriculture and Forestry
Centroid Samling was tested on 21 logs of Ash ( Fraxinus angustifolia subsp. oxycarpa), 38 logs of Spruce ( Picea orien-talis (L.) Link.), and 33 logs of Beech ( Fagus orientalis Lipsky.) all of which were measured in detail. The wolume of each log was estimated using Huber's, Smalian's, Newton, Riecke's, Hosfeld's formulas and Centroid Sampling. These estimates were compared with "true" volume of each log which was determined by aggregating the volumes of measured short sections (1 m.) using Smalian's formula. The mean error of the Centroid estimate of the log volumes was not significant for Fraxinus angustifoliasubsp. oxycarpa, …
Determination Of Hydraulic Performances Of In-Line Emitters, Bülent Özeki̇ci̇, Sefer Bozkurt
Determination Of Hydraulic Performances Of In-Line Emitters, Bülent Özeki̇ci̇, Sefer Bozkurt
Turkish Journal of Agriculture and Forestry
The efficiency of trickle irrigation systems depends directly on the uniformity with which water is discharged from the emission devices throughout the system. Ideally, all emitters in the system should discharge equal amounts of water. One major cause of flow rate difference between two identical emitters from the same manufacturer is the manufacturing variation. In this study, manufacturers' rated discharges and coefficient of manufacturing variation values were compared with tested values for various in-line emitters. Discharge rates from 12 different types of trickle irrigation emitters were collected at six different operating pressure levels. Pressure compensating emitters were tested at 50, …

Exclusive Disjunctions In Indefinite And Maybe Information In Relational Databases, Taflan İ. Gündem
Exclusive Disjunctions In Indefinite And Maybe Information In Relational Databases, Taflan İ. Gündem
Turkish Journal of Electrical Engineering and Computer Sciences
Incorporating indefinite information into databases has been studied extensively. In this paper, we propose a structure called an E-table to represent maybe information and inclusive and exclusive disjunctions. We define the type of redundancies in E-tables and show how to eliminate them. Also we present an extended relational algebra to operate on E-tables. In this paper we expand the concepts and operations defined by Lin and Sunderraman [1] in order to accommodate exclusive disjunctions in relational databases.
