‎two types of properties for linear connections (natural and almost paracontact metric) are discussed in almost paracontact metric geometry with respect to four linear connections‎: ‎levi-civita‎, ‎canonical (zamkovoy)‎, ‎golab and generalized dual‎. ‎their relationship is also analyzed with a special view towards their curvature‎. ‎the particular case of an almost paracosymplectic manifold giv...

in this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (malus domestica) skin and flesh of six iranian cultivars, including: ‘golab kohanz’, ‘sib torsh dirras’, ‘ghara yapragh’, ‘torkman’, ‘ghezel alma’ and ‘abbasi mashhad’, and four commercial cultivars including: ‘golden delicious’, ‘red delicious’, ‘braeburn’ a...

the effects of a nano-emulsion chitosan-based coating on enhancing the shelf-life and quality of golab kohanz apples were studied. the nano-emulsion coating containing chitosan with a concentration of 2000 ppm was applied for coating of golab kohanz apples. coated and uncoated apples were packed in normal packaging cardboards and kept at 2 ± 1 °c with a relative humidity within 80-85%. flesh fi...

the investigations were carried out in 2007 on the fruit of 7 native early-ripening apple cultivars grown in karaj climatic conditions, harvested in two phenological stages of maturity and ripenning. the harvested samples were stored at (0 ± 0.5) c and (85 ± 5) % of humidity. the measured sensorial traits consisted in: aroma, flavor, sweetness, flesh quality and general acceptability achieved ...

The article provides an assessment of the quality fruits promising apple tree hybrids Belarusian selection.
 Promising with a complex economic and biological characteristics (appearance, taste, keeping quality, marketability)
 were identified – 2005-15/2-I (96-41/5 × Golab Kohanz), 2005-16/1-I (Zorka Start), 2006-23/26-II (Nadzejny open
 pollinated). This sampling will be used in...

the internal infections of erwinia amylovora have important roles for disease beginning in the spring and dissemination of inoculum through infected vegetative planting material and nursery trees. in this study, we survey internal infection of erwinia amylovora in symptomless commercial apple cultivars in karaj and damavand cities, using optimized diagnostic methods such as plating on semi sele...

The objective of this study involves the optimise process of a sorting machine for spherical fruits, which are currently manually classified with a low level of efficiency in Iran. An instrumentation system is modelled and fabricated for the development of a fruit sorting machine. Mechanical components and control system are assembled on a chassis for fruit transferring and classifying. A gravi...
