2. The Effect of Water Parameters and Dissolved Minerals on the Hematological Parameters of during Breeding Period Catfish (Silurus glanis)
Abstract In this study, the blood parameters of catfish (Silurus glanis Linnaeus, 1758) inhabiting Çelik Lake (Adıyaman, Turkey) were investigated. The study was conducted between April 2013 and October 2013. After obtaining a blood sample from each catfish has been hematologically analyzed. Then, the water temperature, dissolved oxygen, pH, calcium, magne

3. Physiological quality of Urochloa brizantha seeds submitted to priming with calcium salts
RESUMO O condicionamento fisiológico proporciona vários benefícios, como melhoria no vigor das sementes e redução no grau de dormência. Em sementes de Urochloa brizantha, geralmente, se utiliza nitrato de potássio (KNO3), que é de difícil aquisição. Nesse sentido, os sais de cálcio se destacam, mas é necessário verificar se proporcionam os mesm

5. Effects of in-office bleaching agent combined with different desensitizing agents on enamel
Abstract Objective: To analyze color change, microhardness and chemical composition of enamel bleached with in-office bleaching agent with different desensitizing application protocols. Materials and Methods: One hundred and seventeen polished anterior human enamel surfaces were obtained and randomly divided into nine groups (n = 13). After recording initi

6. Impact of Nitrate and Ammonium ratio on Nutrition and Growth of two Epiphytic Orchids
Abstract Phalaenopsis and Dendrobium do not grow and flower well with 100% ammonium (NH4-N); and there are detailed studies on the effects of nitrate (NO3-N) and ammonium ratios on the flowering, but no information about accumulation of other nutrients and the effects of ammonium toxicity on orchids. For this reason, two experiments were carried out with orc

8. Nitrogen fertilization in top dressing for wheat crop in succession to soybean under a no-till system
ABSTRACT Agricultural intensification to improve wheat yield has increased the demand for nitrogen fertilizers. This study aimed to investigate the wheat response in succession to soybean due to application of nitrogen rates and sources in top dressing, as well as to determine the N rates of maximum technical yield (MTY) and maximum economic yield (MEY). A f

10. Association of swine wastewater and mineral fertilization on black oat production
ABSTRACT Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The o

11. Effect of bleaching agents containing fluoride or calcium on enamel microhardness, roughness and permeability
Abstract Aim: To evaluate the effect of different in-office bleaching agents on the permeability, roughness and surface microhardness of human enamel. Methods: For evaluation of roughness and microhardness, 40 hemi-faces of 20 premolars were subjected to initial roughness (Ra parameter) and microhardness (VHN) measurements. Thirty-two premolar's crowns w

12. Establishment of growth medium and quantification of pollen grains of olive cultivars in Brazil's subtropical areas
ABSTRACT Pollen grain germination in vitro indicates viability and consequently provides information related to fruit set. It also assists in the development of hybrids. Along with a suitable species, a standard culture medium is essential for evaluating pollen viability. It should contain a gelling agent consisting of carbohydrates and enhancer elements as
