Mydriasis induced hyphema in a patient with rubeosis iridis

Hyphema is the presence of blood in the anterior chamber of the eye. The blood may completely or partially cover the pupil and cause decrease in visual acuity. Other signs and symptoms of hyphema include visible blood in the front of the eye, pain, and sensitivity to light. The most common cause of hyphema is ocular trauma, usually a blunt or lacerating one. Other causes of hyphema include intraocular surgery, eye infections caused by herpes virus, cancer of the eye, artificial lens implants and blood clotting problems such as hemophilia, sickle cell anemia and von Willebrand disease. Hyphema may also occur spontaneously in conditions such as rubeosis iridis, juvenile xanthogranuloma, myotonic dystrophy and iris melanoma. The purpose of this case report is to point to the management of hyphema which occurs after administration of mydriatic drugs

Eleştirel Yaklaşım Bağlamında Teknoloji ve Hegemonya İlişkisini Tartışmak

Teknolojinin günümüzde hızla gelişmesi toplumsal hayatta değişimlere neden olmaktadır. Teknolojiyi kullanan devletler, gruplar ve şirketler onun sağladığı avantajlardan etkin bir biçimde faydalanmaktadırlar. Bunlardan en önemlisi hegemonyadır. Bu makalede teknolojinin toplumları yöneten sınıflar için elverişli bir aygıt olduğu ve hegemonyanın sağlanması için bu araçlardan faydalanıldığı iddia edilmektedir. Teknolojinin ekonomik süreçteki etkisi siyasal ekonomi yaklaşımı ile ortaya konulması amaçlanmıştır. İleri teknoloji düzeninin akılcıl olması ve etrafında şekillenen mantıksal düzen, doğanın kurallarını bir kenara bırakarak ve kendi düzenini ortaya koymasından ötürü gerçekleşmektedir. Kitlesel savaşlar ve kıyımlar eskisi kadar yoktur, onun yerine sömürgeci düzende az gelişmiş yapıları yıkarak kendi mantıksal-sömürgeci düzeninin yerine geçmektedir. Bu yer değiştirme faaliyetinde her şey yukarıdan dayatılarak şekillendirilmektedir. Karşıtlar soğurularak etkisiz hale getirilmekte ve düzene ve sisteme zararsız olarak yeniden düzen içerisinde var olmalarına izin verilmektedir. Teknoloji sayesinde devletler ve çok uluslu şirketler bu evreni medya ile inşa etmektedirler. Teknoloji hâkim sınıfların ellerinde kontrol ve hegemonya sağlamak için kullanılmaktadır. Sonuçta teknoloji sayesinde kapitalist yapının güç, sermaye ve iktidar baskısını insanlara dayattığı ortaya çıkmaktadır

Comparison of Phytochemicals and Antioxidant Capacities of Some Standard and Organically Grown Highbush Blueberries (Vaccinium corymbosum L.)

Blueberries are considered one of the important fruits for health benefits due to their antioxidant capacity and rich natural compounds. In this study, northern highbush blueberry cultivars ‘Brigitta’, ‘Patriot’, ‘Bluecrop’, ‘Darrow’ and ‘Bluejay’ (Vaccinium corymbosum L.) grown in standard and organic conditions in Black Sea Region were compared. Berry weight (g), TSS (%), organic acids (tartaric, ascorbic and citric acid), sugars (fructose and glucose), total phenolic compounds (μg GAE gfw-1), total monomeric anthocyanins (TMA) (μg cy-3-glu gfw-1) and total antioxidant activity (FRAP and TEAC) were determined. Berries were harvested when 75% of the skin color changed into blue color (June 15, 2010). Quantities of ascorbic acid, glucose, total phenolics and TMA changed between 0.015-0.027 g kg-1, 3.79- 4.75 g 100g-1, 1593.3-2362.4 μg GAE gfw-1, 57.7-267.2 μmol TE gta-1 respectively. Total antioxidant activity changed between 3.80-6.51 FRAP μmol TE g fw-1 and 2.32-5.29 TEAC μmol TE g fw-1. While blueberries grown in standard system exhibited higher tartaric acid, citric acid, ascorbic acid, glucose, TEAC and berry weight, blueberries grown organically showed higher total phenolics, TMA, FRAP and malic acid

Spatial interaction modeling of interregional commodity flows

Drawing from both the spatial price equilibrium theoretical framework and the empirical literature on spatial interaction modeling, this paper expands models of interregional commodity flows (CFs) by incorporating new variables and using a flexible Box-Cox functional form. The 1993 US commodity flows survey provides the empirical basis for estimating state-to-state flow models for 16 commodity groups over the 48 continental US states. The optimized Box-Cox specification proves to be superior to the multiplicative one in all cases, while selected variables provide new insights into the determinants of state-to-state CFs

In the study, root length (cm), root surface area (cm2), root diameter (mm), root volume (cm3), root tip number (piece), root branching number (piece), and root intersection number (piece) were determined. Total root length was determined between 330.05 - 595.40 cm (%252339%253BRizellim%252339%253B%252FSO4 and %252339%253BÇeliksu%252339%253B%252F140Ru) and mean root diameter of 2.04 - 3.13 mm (%252339%253BÇeliksu%252339%253B%252F140Ru and %252339%253BRizessi%252339%253B%252F110R). Negative relationships were found between root length and mean root diameter. Among the rootstocks, the highest root surface area was 399.67 cm2, root volume was 29.32 m3, the number of root tips was 1605.75, the number of root forks was 5421.89, and the number of root crossing was 671.61 on 110R rootstock. In all combinations obtained as a result of the study, it was determined that the rootstocks showed good root development and were in harmony with the new foxy grape cultivars

A reduced-uncertainty hybrid evolutionary algorithm for solving dynamic shortest-path routing problem

The need for effective packet transmission to deliver advanced performance in wireless networks creates the need to find shortest network paths efficiently and quickly. This paper addresses a Reduced Uncertainty Based Hybrid Evolutionary Algorithm (RUBHEA) to solve Dynamic Shortest Path Routing Problem (DSPRP) effectively and rapidly. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are integrated as a hybrid algorithm to find the best solution within the search space of dynamically changing networks. Both GA and PSO share context of individuals to reduce uncertainty in RUBHEA. Various regions of search space are explored and learned by RUBHEA. By employing a modified priority encoding method, each individual in both GA and PSO are represented as a potential solution for DSPRP. A Complete statistical analysis has been performed to compare the performance of RUBHEA with various state-of-the-art algorithms. It shows that RUBHEA is considerably superior (reducing the failure rate by up to 50%) to similar approaches with increasing number of nodes encountered in the networks
