Further evaluation of selected Sarilop (Calimyrna) clones
No full text1st International Symposium on Fig -- JUN 24-28, 1997 -- IZMIR, TURKEYTurkey is the major producer of dried figs. All the production comes from plantations of the Sanlop (=Calimyrna) variety in the western Aegean Region. Although this variety is known to possess a superior dried fruit quality, it is susceptible to ostiole-end cracks, sunscald and has a wide opening which permits the entrance of insects. In order to overcome the quality related problems, a study was started during the period, 1975-1978 to select high performing Sanlop clones in the region (Eroglu, 1982). In 1982, nursery trees of 86 clones were propagated and planted at the Fig Research Institute. Through a project carried out in 1991-1994, 86 clones were evaluated and 10 clones were determined to rank at higher positions and accepted as promising. These clones were further evaluated in 1994-1996 in terms of dried fruit quality, yield and ripening season. Data obtained for three seasons was subjected to a statistical analysis. High deforming clones will be recommended for further studies.Int Soc Hort Sc

Fruit and leaf nutritional status of some fig clones and cultivars and relationships with some sugar fractions
No full text1st International Symposium on Fig -- JUN 24-28, 1997 -- IZMIR, TURKEYPrimary and secondary plant nutrients and sugar fractions were determined in leaf and fruit samples of 10 fig cultigens grown under the same nutritional conditions at the Erbeyli Fig Institute (Aydin/Turkey). The evaluation of the result shows that Ca and Zn contents were at deficiency levels. The dominant sugar fractions were fructose and glucose. Among the investigated cultigens, Goklop, Bursa Black (1), Sarilop (37) were found to exceed the others in terms of fructose and total sugar contents. A significant correlation was determined between fructose, alpha- glucose and total sugar content and leaf Mn that can be attributed to its role in carbohydrate metabolism.Int Soc Hort Sc
Vibration damage trial on some fig cultivars
No full text1st International Symposium on Fig -- JUN 24-28, 1997 -- IZMIR, TURKEYThere is a significant amount of damage to fruits and vegetables during transport. Due to repeated vibration forces skin rupture appears on fruit. In this research, an in-transit vibration simulator was used to determine the extent of damage on fig fruits. In laboratory tests, figs were subjected to different levels of "vibration intensity" for different durations. The effects of duration, box type, vibration intensity and the position of the fruit on fruit damage were determined.Int Soc Hort Sc
Schwarz problem for higher order linear equations in a polydisc
No full textCelebi, Ahmet Okay/0000-0001-5256-1035; Aksoy, Umit/0000-0002-6014-1898In this paper, we discuss the Schwarz boundary value problem for higher order linear complex differential equations in the unit polydisc of C-2. After the relevant preparations, we give the solution for a model equation with homogeneous boundary conditions. Then we obtain the solutions of a linear equation involving Schwarz boundary conditions on the unit polydisc
Changes in Quality of Dried Fig Fruit and Processed Fig Products under Cold and Ambient Storage Conditions
No full text6th International Postharvest Symposium -- APR 08-12, 2009 -- Antalya, TURKEYTurkey has a significant share in the world dried fig (Ficus carica 'Sarilop') trade. Dried fig is generally exported as semi-processed intermediate goods. During the last years, there are attempts to develop new processed products from fig paste. The research was carried out in 2006-2007 to determine the quality changes that limit market life of sun-dried fig fruits destined for direct consumption and sweets prepared from fig paste. Dried fig fruit (manipulated as Lerida type) and two products processed from fig (fig delight with walnut and sesame coated paste) were stored under cold (3 +/- 0.5 degrees C, 55-65% relative humidity) and ambient storage conditions for 12 months. Samples were taken monthly to monitor quality changes and microbial load. Under ambient storage conditions, quality losses started in dried fig and fig delight after 7 months and in sesame coated paste after 8 months of storage due to increased temperatures and lower relative humidity in the spring. Cold storage conditions extended storage ability and no significant changes were observed for a 12 month period.Int Soc Hort Sci (ISHS)TARIS Research and Development Center [AR-GE 2006 I/1]This study was partially funded by the TARIS Research and Development Center under grant AR-GE 2006 I/1
Technical and economic feasibility of seabass fry production according to organic techniques
No full textOver the past few years, consumers have been increasing their awareness about environmental, health and
safety concerns, gradually changing their habits in
favour
of organic food. In Europe, the organic aquaculture
is legislated by Comm
ission Regulation (EC) 710/2009. In Italy, only ten farms are involved in the supply of
certified organic fish and only some pilot projects were carried out for organic farming of different species.
Therefore, the purpose of this research was to evaluate o
rganic technical feasibility and production costs,
comparing them with conventional production. This study contains the first considerations about organic
production and its relative costs for seabass fry, one of the most reared species of the country. Con
version
to organic production naturally involves additional costs concerning the conversion process itself, the
production of a new type of product and the lower output. In fact, results have shown that certification and
feed costs represented the most sig
nificant difference between conventional and organic production.
Economic Performance of Pre-Crops in a Three-Year Rotation Program for Organic Vegetable Production
No full text28th International Horticultural Congress on Science and Horticulture for People (IHC) / International Symposium on Organic Horticulture - Productivity and Sustainability -- AUG 22-27, 2010 -- Lisbon, PORTUGALA four year experiment is being carried out, at Ege University Department of Horticulture, in which three different pre-crops are tested under an organic management system as compared to fallow. The aim of the experiment is to identify the most suitable rotation program for organic vegetable production in Turkey. Vicia sativa (common vetch), Brassica oleracea var. italica (broccoli), Vicia faba 'Sevilla' (faba bean) and fallow are tested as preceding (winter) crops. During the experiment carried out between 2007 and 2009, the main crops were tomato (2007), zucchini (2008) and pepper (2009). Broccoli represented the farmers' choice as a winter vegetable. Vetch (incorporated) and faba bean (partially harvested and incorporated) were selected as legumes well adapted to the regional conditions. Soil fertility was maintained by incorporation of the crop residues at the end of both cycles and addition of organic-certified commercial compost (Bioaktif) and compost tea during the main cycle. All the management, including disease and pest management, was carried out according to the organic regulations valid in Turkey and the EU. During the production seasons, all variable costs and revenue, during both the pre-crop and main crop cycles, were recorded and gross margin calculated for each treatment. Economic analysis showed that broccoli as a pre-crop required the highest variable costs followed by faba bean, vetch and fallow, in all three years. Total revenue was the highest in plots where broccoli was the pre-crop. It is followed by faba bean plots mostly because higher yields were obtained in main crop plots following faba bean. The least profitable was fallow - main crop rotation. Broccoli plants also have some extra benefits like adding a high amount of biomass to soil and suppressing weed growth due to shading and allelopathic effects.Int Soc Hort Sci (ISHS
A Dynamic Subfilter-scale Stress Model for Large Eddy Simulations Based on Physical Flow Scales
No full textWe propose a new definition of the length scale in an eddy-viscosity model for large-eddy simulations (LES). This formulation extends and generalizes a previous proposal [Piomelli, Rouhi and Geurts, Proc. ETMM10, 2014], in which the LES length scale was expressed in terms of the integral length-scale of turbulence determined by the flow characteristics and explicitly decoupled from the simulation grid; this approach was named Integral Length-Scale Approximation (ILSA). As in the original ILSA, the model coefficient was determined by the user, and required to maintain a desired contribution of the unresolved, subfilter scales (SFS) to the global transport. We propose a local formulation (local ILSA) in which the model coefficient is local in space, allowing a precise control over SFS activity as a function of location. This new formulation preserves the properties of the global model; application to channel flow and backward-facing step verifies its features and accuracy
