    Cutting parameters of some grape varieties subject to the diameter and age of canes
    (Parlar Scientific Publications, 2019) Esgici R.; Goksd Pekitkan F.; Ozdemir G.; Guzel E.; Sessiz A.
    Grape is an important product for the economy of Turkey and it will continue to play an important role in worldwide grape production due to its large number of varieties, favorable ecological conditions and large production areas. However, pruning and harvesting of grape berries are performed manually with a labor intensive procedure. Therefore, production cost is very high and labor efficiency is low in vineyards. However, pruning and harvesting are the most critical operations in vineyard management. Information regarding the cutting of canes of different grape varieties is very important for a proper harvest machine design as well as the efficient use of energy. In this study, cutting force and cutting energy were measured by considering the factors of grape canes diameter and age of canes. One and two year old grape canes from the Genc Mehmet, Bogazkere and Okuzgozu local varieties were used as experimental material. The canes were obtained from a commercial vineyard in the Diyarbakır province located in southeastern Turkey. Lloyd, LRX plus series, materials testing machine was used for cutting tests. Statistically significant differences were determined between the cutting properties of grape varieties. The cutting force and cutting energy increased with increasing diameter and age of canes. © 2019 Parlar Scientific Publications. All rights reserved.

    Pediatric orbital multifocal cavernous hemangiomas associated with bilateral arachnoid cysts of the middle cranial fossa. Case report and review of the literature
    (2005) Tatli M.; Guzel A.; Keklikci U.; Guzel E.
    Cavernous hemangiomas of the orbit are benign vascular growths that commonly occur in adults and account for 6% of all intraorbital tumors. Multifocal intraorbital cavernous hemangiomas are quite rare. The reported incidence of arachnoid cysts accounts for only 1% of lesions that occupy intracranial space, and they are nearly always sporadic and single. So far, the authors have not encountered any study reporting the coexistence of bilateral arachnoid cysts of the middle cranial fossa and orbital multifocal cavernous hemangiomas. In this report, they describe a 10-year-old boy with such a hemangioma that included the eyelid, conjunctiva, and retrobulbar space. His was the first case of a surgically treated pediatric orbital multifocal cavernous hemangioma associated with bilateral arachnoid cysts of the middle cranial fossa. An association between arachnoid cysts, intracranial cavernous malformations, and bilateral arachnoid cysts and metabolic disorders has been reported. The authors report on the coexistence of orbital multifocal cavernous hemangiomas and bilateral arachnoid cysts of the middle cranial fossa. Based on these observations, they believe that all patients with bilateral temporal arachnoid cysts should be screened for genetic disorders. In addition, the possibility of orbital cavernous malformations should be kept in mind for the follow-up period, and patients should be evaluated for possible symptoms of this condition.
